Technical Field

The present invention relates to a component replenishment management system that manages replenishment of component storage members to a component supply device attached to a mounting machine that mounts components onto a substrate, and a component mounting system provided with the component replenishment management system.

Background

A mounting machine for mounting electronic components (hereinafter, simply referred to as "components") on a substrate such as a printed circuit board to produce a mounted substrate includes a component supply device capable of mounting a component housing member housing the components. When the mounting machine produces the mounted substrate, the operator performs a replacement adjustment operation of mounting the component storage members necessary for production on the component supply device or the like according to the production plan of the mounted substrate, and then starts the production. In the production of the mounted substrate, in order to avoid the production stop of the mounted substrate due to the component supply stop of the component supply device, an operator performs the replenishment work of the component accommodating member to the component supply device according to the component consumption amount generated along with the production of the mounted substrate.

For example, patent document 1 discloses a technique for improving the efficiency of replenishment work performed by an operator. In the technique disclosed in patent document 1, a process of predicting a time period in which component supply interruption of a plurality of component supply devices (feeders) attached to respective mounting machines is predicted is executed in a component mounting line in which the mounting machines are arranged, and a process of performing a replenishment job by a dispensing operator in the component supply interruption prediction time period is executed.

Disclosure of Invention

However, in the technique disclosed in patent document 1, the supply timing for supplying the component storage member to each component supply device is individually set. Therefore, if the component supplying devices are replenished at replenishment timings that are individually set, the worker needs to go to the mounting machine with the component supplying device at a high frequency, and runs east and west among the mounting machines. As a result, the load of the replenishment work by the operator increases.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a component replenishment management system capable of reducing a load of a worker for replenishing a component housing member of a component supply device, and a component mounting system including the component replenishment management system.

A component replenishment management system according to an aspect of the present invention manages replenishment of component storage members to each of a plurality of component supply apparatuses provided in a mounting machine that mounts components on a board to produce a mounted board, the component supply apparatuses being capable of mounting a plurality of component storage members in which components are stored, the component replenishment management system comprising: an acquisition unit configured to acquire a management start time indicating a start time of management of replenishment of the component storage member for each of the plurality of component supply devices; a setting unit that sets a specific period from the management start time to a specific time after a predetermined specific time has elapsed; a component supply monitoring unit that monitors a supply state of components in each of the plurality of component supply devices, and determines a resupply possible time, which is a time at which a preceding component accommodating member, which has first been subjected to component supply, of the plurality of component accommodating members becomes a component supply-disconnection state and a new component accommodating member can be replenished, for each of the plurality of component supply devices; and a replenishment target specifying unit that specifies the component supply device whose replenishment possible timing is a timing earlier than the specific timing as a component replenishment target device to be replenished by the new component housing member in the specific period.

Detailed Description

Hereinafter, a component replenishment management system and a component mounting system according to an embodiment of the present invention will be described with reference to the drawings.

[ integral Structure of component mounting System ]

Fig. 1 is a diagram schematically showing a configuration of a component mounting system 1 according to an embodiment of the present invention. The component mounting system 1 includes a mounting machine 2, a component replenishment management system 3, a mounting machine operation management device 4, a production schedule management device 5, and a replacement adjustment management device 6. In the component mounting system 1, the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the mounting change adjustment management apparatus 6 are management apparatuses that are connected to the component replenishment management system 3 so as to be capable of data communication and that manage production of the mounted substrates by the mounting machine 2. In the component mounting system 1, a plurality of mounting machines 2 are arranged in parallel. In the example shown in fig. 1, 4 mounting machines 2 are arranged in parallel.

< Structure of mounting machine >

First, the structure of the mounter 2 will be described with reference to fig. 2. Fig. 2 is a plan view showing the structure of the mounter 2. In the following, the directional relationship will be described using XY orthogonal coordinate axes. One direction side in the X-axis direction is referred to as "+ X side", and the other direction side opposite to the one direction side in the X-axis direction is referred to as "-X side". One direction side in the Y axis direction is referred to as "+ Y side", and the other direction side opposite to the one direction side in the Y axis direction is referred to as "-Y side".

The mounter 2 mounts components on a substrate P to produce a mounted substrate. The mounting machine 2 includes a main body frame 21, a transfer beam 22, a conveyor 23, a component supply unit 24, a head unit 25, a first drive mechanism 26, and a second drive mechanism 27.

The main body frame 21 is a structure in which the respective parts constituting the mounting machine 2 are arranged, and is formed in a substantially rectangular shape in a plan view viewed from a direction orthogonal to both the X-axis direction and the Y-axis direction. The conveyor 23 extends in the X-axis direction and is disposed on the main body frame 21. The conveyor 23 conveys the substrate P in the X-axis direction. The substrate P is conveyed by the conveyor 23 and positioned at a predetermined working position (a mounting position where components are mounted on the substrate P).

The component supply units 24 are arranged in 2 locations in the X-axis direction, that is, 4 locations in total, in the + Y side and-Y side region portions in the Y-axis direction of the main body frame 21. The component supply unit 24 is used to supply components to be mounted on the substrate P, and includes a plurality of component supply devices 241. The component supplying device 241 is a device capable of mounting a component housing member housing components. In the present embodiment, the component supplying apparatus 241 is a tape feeder configured to wind a component storage tape that stores components at predetermined intervals around a reel as a component storage member and to feed the component storage tape from the reel.

Tape feeders are generally roughly classified into a splice type feeder and an automatic loading type feeder (AF). The splice feeder is configured to attach 1 reel, and to connect the leading end portion of a preceding component storage tape and the distal end portion of a succeeding component storage tape by bonding them with a splice tape or the like in order to transit from the component storage tape to the succeeding component storage tape before the component storage tape is fed out from the reel and becomes a component break. That is, in the splicing feeder, since the splicing work with the splicing tape or the like is performed before the feeding of the component storage tape from 1 reel is completed and the component is cut, the timing of feeding the reel on which the subsequent component storage tape is wound is limited to the point of time when the feeding of the preceding component storage tape is completed.

On the other hand, the AF is configured to be able to mount a plurality of reels, and when the feeding of the component storage tape from a preceding reel of the plurality of reels on which the component storage tape that has been supplied first (hereinafter referred to as a "preceding component storage tape") is wound is completed, the component storage tape is automatically fed from a subsequent reel on which the subsequent component storage tape is wound without performing the splicing operation. That is, in AF, the timing of replenishment of a new reel is not limited to the point in time when feeding of a component storage tape from a preceding reel on which a preceding component storage tape is wound is completed, and there is a degree of freedom in comparison with a splice feeder.

In the present embodiment, although a tape feeder provided in component supply unit 24 may be a combination of a splice feeder and AF, a plurality of AF capable of mounting a plurality of reels as component storage members are provided as component supply device 241. The component supply device 241 configured by this AF will be referred to as "AF 241" hereinafter. Details of the AF241 will be described later.

The movable beam 22 extends in the X-axis direction, and is supported by the main body frame 21 so as to be movable in a predetermined movement direction (Y-axis direction). A head unit 25 is mounted on the travel beam 22. The head unit 25 is mounted on the transfer beam 22 so as to be movable in the X-axis direction. That is, the head unit 25 can move in the Y-axis direction along with the movement of the transfer beam 22, and can move in the X-axis direction along the transfer beam 22. The head unit 25 is movable between the component supply unit 24 and a predetermined working position of the substrate P conveyed by the conveyor 23, takes out components from the component supply unit 24, and mounts the taken-out components on the substrate P.

The first drive mechanism 26 is disposed at the + X side and-X side ends of the main body frame 21. The first drive mechanism 26 is a mechanism that moves the transfer beam 22 in the Y-axis direction. The first drive mechanism 26 is configured to include, for example, a drive motor, a ball screw extending in the Y-axis direction and coupled to the drive motor, and a ball nut disposed on the travel beam 22 and screwed to the ball screw. The first drive mechanism 26 having such a configuration moves the movable beam 22 in the Y-axis direction by the ball nut moving forward and backward along the ball screw in accordance with the rotational drive of the ball screw by the drive motor.

The second drive mechanism 27 is disposed on the travel beam 22. The second driving mechanism 27 is a mechanism that moves the head unit 25 in the X-axis direction along the transfer beam 22. The second drive mechanism 27 is configured to include, for example, a drive motor, a ball screw extending in the X-axis direction and coupled to the drive motor, and a ball nut disposed on the head unit 25 and screwed into the ball screw, similarly to the first drive mechanism 26. The second drive mechanism 27 having such a configuration moves the head unit 25 in the X-axis direction by the ball nut moving forward and backward along the ball screw in accordance with the rotational drive of the ball screw by the drive motor.

< Structure of device supply section having AF >

Next, the structure of the element supply unit 24 including the AF241 will be described in detail with reference to fig. 3 to 7. Fig. 3 is a diagram schematically showing the configuration of the component supply unit 24 in the mounting machine 2. Fig. 4 to 6 are explanatory diagrams of the component supply operation in the AF241 of the component supply section 24. Fig. 7 is a perspective view showing the component housing tape 243 of the AF241 mounted in the component supply section 24.

The component supply units 24 arranged at 4 positions of the main body frame 21 are formed by arranging a plurality of AFs 241 on the carriage 242. The AF241 can mount a plurality of reels 2420 around which the component storage tape 243 is wound.

Before describing the structure of the AF241, the element housing tape 243 is described with reference to fig. 7. The component accommodation tape 243 is composed of a carrier tape 2431 and a cover tape 2434. The carrier tape 2431 is a tape in which a plurality of component accommodating portions 2433 for accommodating components E are arranged at predetermined intervals. Further, the carrier tape 2431 has a conveying force transmission hole 2432 arranged at a predetermined interval at one end portion in the width direction, and the conveying force transmission hole 2432 is fitted to teeth of a first sprocket 2412A and a second sprocket 2413A in AF241 to be described later and is transmitted with a conveying force for feeding out the component storage tape 243 by the first sprocket 2412A and the second sprocket 2413A. Cover tape 2434 is a tape that is attached to carrier tape 2431 so as to cover component housing 2433.

As shown in fig. 3, AF241 is mounted on feeder mounting portion 2417A provided in component supply portion 24. Specifically, component supply unit 24 is provided with feeder attachment unit 2417A and reel support unit 2419. Feeder attachment portion 2417A is provided with a plurality of grooves 2417B arranged at fixed intervals in the X-axis direction and extending parallel to each other in the Y-axis direction, and a fixed base 2417C extending in the X-axis direction at a position forward of grooves 2417B. AF241 is provided in each groove 2417B, and each AF241 is fixed to a fixed base 2417C. Thus, in the component supply section 24, a plurality of AFs 241 are provided in parallel on the carriage 242.

Reel supporting portion 2419 is located at the lower rear side of feeder attachment portion 2417A, and supports first reel holder 2419A and second reel holder 2419B that rotatably support reel 2420 in a state of being separated from each other in the vertical direction. A component storage tape 243 is wound around a reel 2420 supported by each of the first reel holder 2419A and the second reel holder 2419B.

AF241 includes feeder main body 2411. AF241 is fixed to stationary stage 2417C in a state where feeder main body 2411 is inserted (set) in groove 2417B. A first sprocket 2412A constituting a first tape feeding unit 2412 and a second sprocket 2413A constituting a second tape feeding unit 2413 separated from the first sprocket 2412A in the Y axis direction so as to be apart from the reel support unit 2419 are rotatably supported by the feeder main body 2411. Each of the first sprocket 2412A and the second sprocket 2413A includes a plurality of teeth arranged at predetermined intervals in the circumferential direction. The teeth of the first sprocket 2412A and the second sprocket 2413A can be fitted into the transmission force transmission holes 2432 of the carrier tape 2431 formed in the component storage tape 243.

The component storage tape 243 wound around the reel 2420 supported by each of the first reel holder 2419A and the second reel holder 2419B is guided to the first sprocket 2412A and the second sprocket 2413A while being guided by a guide roller 2418 disposed at the upper end of the reel support portion 2419. The component storage tape 243 in which the transmission force transmission hole 2432 is fitted to the teeth of the first sprocket 2412A and the second sprocket 2413A is fed by the rotation of the first sprocket 2412A and the second sprocket 2413A, and the component E is taken out at the component supply position P1.

AF241 further includes a tape support member 2414 detachably fixed to the rear end portion of feeder main body 2411, an operation input unit 2415 disposed on the upper surface of the rear portion of feeder main body 2411, and first and second tape detection sensors 2416A and 2416B.

As shown in fig. 3, tape support member 2414 divides the rear end portion of tape travel passage 2414A through which component storage tape 243 travels inside feeder main body 2411 into upper and lower 2 passages (upper passage 2414AA, lower passage 2414AB), and supports component storage tape 243 passing through upper passage 2414AA from the lower side. Specifically, the rear end portion of the tape passage 2414A is formed in a shape that extends in the vertical direction from the front toward the rear. Tape supporting member 2414 is inserted into tape running passage 2414A from the rear of feeder main body 2411, and is detachably fixed to feeder main body 2411. Thus, the rear end portion of the tape travel passage 2414A is divided into an upper passage 2414AA and a lower passage 2414AB by the tape support member 2414.

The first tape detection sensor 2416A and the second tape detection sensor 2416B are provided in a state facing the tape travel path 2414A, and detect the presence or absence of the component storage tape 243 passing through the tape travel path 2414A. More specifically, the first tape detection sensor 2416A is provided at a position forward of the point of confluence between the upper passage 2414AA and the lower passage 2414AB and facing the tape travel passage 2414A from below. On the other hand, the second tape detection sensor 2416B is provided at a position facing the upper passage 2414AA from above, and detects the presence or absence of the component storage tape 243 in the upper passage 2414 AA.

The operation input unit 2415 is used for the operator to feed and reverse the component storage tape 243 as necessary.

Hereinafter, the element supply operation of the AF241 configured as described above will be described with reference to fig. 3 to 6. First, as a preparation operation, the worker attaches reel 2420 on which previous component storage tape 243 is wound to first reel holder 2419A on the lower layer of reel support portion 2419, and inserts the distal end portion of component storage tape 243 wound on reel 2420 into upper passage 2414AA from the rear of feeder main body 2411. Thus, the distal end portion of the preceding component storage tape 243 is supported by the tape support member 2414 in a state of being fitted to the first sprocket 2412A. Thereafter, the operator operates operation input unit 2415 to input an instruction to rotate first sprocket 2412A, feed component storage tape 243, and fit the distal end portion of component supply tape 243 to second sprocket 2413A.

When the preparation work is completed, the component supply operation of the AF241 is started. In AF241, second sprocket 2413A rotates, thereby feeding out component housing tape 243. Further, the first sprocket 2412A is configured to be able to idle, and in this case, the component storage tape 243 can be fed out only by rotating the second sprocket 2413A.

Next, in a state where previous component storage tape 243 is being fed from reel 2420, the operator removes tape support member 2414 from feeder main body 2411. When the tape supporting member 2414 is removed, as shown in fig. 3, the component storage tape 243 is displaced to the bottom surface of the tape travel path 2414A due to its own weight. This releases the engagement of the preceding element accommodating belt 243 with the first sprocket 2412A. At this time, since the component storage tape 243 is fitted to the second sprocket 2413A, even if the fitting to the first sprocket 2412A is released, the component storage tape 243 is continuously fed by the rotation of the second sprocket 2413A.

Next, in a state where preceding component storage tape 243 is being fed from reel 2420, the worker mounts tape support member 2414 to feeder main body 2411, and moves reel 2420 on which preceding component storage tape 243 is wound from first reel holder 2419A on the lower layer to second reel holder 2419B on the upper layer, as shown in fig. 4. Next, in a state where previous component storage tape 243 is being fed out from reel 2420 supported by second reel holder 2419B on the upper stage, the worker attaches reel 2420 around which subsequent component storage tape 243 is wound to first reel holder 2419A on the lower stage as shown in fig. 5, and inserts the distal end portion of component storage tape 243 into upper passage 2414AA from the rear of feeder main body 2411. Thereby, the distal end portion of the subsequent component storage tape 243 is supported by the tape support member 2414 in a state of being fitted to the first sprocket 2412. In this way, the reel 2420 around which the subsequent component tape 243 is wound can be mounted without causing a component break in the preceding component tape 243 wound around the reel 2420.

Thereafter, when the leading component storage tape 243 is completely drawn out from the reel 2420 supported by the second reel holder 2419B on the upper stage and the presence of the leading component storage tape 243 is detected as being absent when the trailing end thereof passes the position of the second tape detection sensor 2416B as shown in fig. 6, the feeding of the following component storage tape 243 from the reel 2420 supported by the first reel holder 2419A on the lower stage is automatically started. Then, the operator removes the reel 2420 that has been disconnected from the second reel holder 2419B on the upper stage, and moves the reel 2420 around which the subsequent component storage tape 243 is wound from the first reel holder 2419A on the lower stage to the second reel holder 2419B on the upper stage. At this time, the operator can supply a new reel on which the component storage tape 243 is wound to the AF 241. A new reel replenished to AF241 is set to the first reel holder 2419A on the lower layer by the operator. Here, the replenishment timing of the new reel is determined by the component replenishment management system 3, and is not limited to the point in time when the reel 2420 on which the preceding component storage tape 243 is wound becomes the component supply/disconnection point.

Further, in a state shown in fig. 5 in which the preceding component storage tape 243 is fed out from the reel 2420 supported by the second reel holder 2419B on the upper stage and the distal end portion of the succeeding component storage tape 243 wound around the reel 2420 supported by the first reel holder 2419A on the lower stage is inserted into the upper passage 2414AA, a new reel cannot be mounted. On the other hand, in the state shown in fig. 6 in which the preceding component storage tape 243 is completely pulled out from the reel 2420 supported by the second reel holder 2419B on the upper stage and the subsequent component storage tape 243 is automatically started to be fed out from the reel 2420 supported by the first reel holder 2419A on the lower stage, a new reel can be mounted.

[ Structure of component replenishment management System ]

The component replenishment management system 3 is a system that manages replenishment of reels as component storage members to each of the plurality of AFs 241 provided in the component supply section 24. The component replenishment management system 3 is configured to perform "concentrated replenishment" in which the reel replenishment operation is performed in a concentrated manner to the AF241 capable of replenishing the reel at the same replenishment timing, in order to reduce the burden of the replenishment operation performed by the operator.

< first embodiment >

Fig. 8 is a block diagram showing the configuration of the component replenishment management system 3 according to the first embodiment. Hereinafter, the component replenishment management system 3 according to the first embodiment will be referred to as a "first component replenishment management system 3". As shown in fig. 1, the first component replenishment management system 3 is connected to the mounting machine operation management apparatus 4, the production plan management apparatus 5, and the replacement adjustment management apparatus 6 so as to be capable of data communication. The first component replenishment management system 3 includes, for example, a microcomputer, and as shown in fig. 8, includes a data communication unit 31, an operation unit 32, a display unit 33, and a control unit 34.

The operation unit 32 includes a touch panel, a numeric keypad, a start key, a setting key, and the like, and accepts operations and various settings of the first component replenishment management system 3 by an operator. The display unit 33 displays the determination result information generated by the replenishment target determination unit 347 and the like of the control unit 34, which will be described later. The data communication unit 31 is an interface circuit for realizing data communication with the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the replacement adjustment management apparatus 6. The data communication unit 31 acquires information transmitted from the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the replacement adjustment management apparatus 6, and supplies the acquired information to the control unit 34. The data communication unit 31 is supplied with the determination result information generated by the replenishment target determination unit 347 or the like from the control unit 34, and transmits (outputs) the determination result information to the mounting machine operation management apparatus 4, the production plan management apparatus 5, and the replacement adjustment management apparatus 6.

Here, the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the replacement adjustment management apparatus 6 connected to the first component replenishment management system 3 in a manner capable of data communication will be described.

The mounting machine operation management device 4 is a device that is provided close to a production line on which substrates of the mounting machine 2 are mounted, and manages mounting operations of the mounting machine 2. The mounting machine operation management device 4 is constituted by a microcomputer, for example. The operator of the production line operates the mounting machine operation management device 4 to control the mounting operation of the mounting machine 2. The mounter operation management apparatus 4 transmits, to the first component replenishment management system 3, component remaining amount information on the total remaining amount of components E stored in the component storage tape 243 wound around the reels 2420 of each reel holder of the first reel holder 2419A and the second reel holder 2419B mounted on each AF241, by an operation of the production line operator. The information on the number of remaining components transmitted from the mounting machine operation management apparatus 4 is input to the first component replenishment management system 3 via the data communication unit 31. The component remaining amount information may be transmitted from the replacement adjustment management apparatus 6 described later. The mounting machine operation management apparatus 4 receives the identification result information generated by the replenishment target identification unit 347 or the like described later and transmitted from the first component replenishment management system 3 via the data communication unit 31. The production line operator performs the operation of replenishing the reel of AF241 based on the determination result information input to the mounting machine operation management device 4.

The production plan management device 5 is a device for managing a production plan for producing the mounted substrate by the mounting machine 2. The production plan management device 5 is constituted by a microcomputer, for example. The production plan management device 5 transmits production plan information on a production plan of the mounted substrate to the first component replenishment management system 3 by an operation of an operator who makes the production plan. Fig. 9 is a diagram for explaining production plan information JH1 transmitted from the production plan management apparatus 5 and input to the first component replenishment management system 3. Production plan information JH1 is information containing at least element required number information JH143 and cycle time information JH 144. The required number of elements information JH143 is information on the required number (number/piece) of elements E required for production of 1-piece mounting substrate. The cycle time information JH144 is information on the time (seconds/chip) required for mounting the element E when producing 1 chip of the mounted substrate.

Specifically, as shown in fig. 9, production plan information JH1 is information in which substrate information JH11 for specifying a substrate P for production of a mounted substrate, production quantity information JH12 indicating the production quantity of the mounted substrate, production order information JH13 indicating the production order of the mounted substrate, and used element information JH14 relating to an element E used when the mounted substrate is produced are associated with each other. The used component information JH14 is information in which component identification information JH141 for identifying the component E, component type identification information JH142 for identifying the component E, the required number of components information JH143, and the cycle time information JH144 are associated with each other. The required number of components information JH143 is set for each component identified by the component identification information JH 141. The cycle time information JH144 is set for each substrate specified by the substrate information JH 11. Referring to fig. 9, for 1 "substrate a" identified by the substrate information JH11, the value of the cycle time indicated by the cycle time information JH144 is the same value ("AAA 1") for each element ("IA 1", "IA 2") identified by the element identification information JH141, and is set to a value corresponding to the substrate if the substrate is different.

The mounting/replacement adjustment management device 6 is a device for managing mounting/replacement adjustment work required for production of the mounted substrate by the mounting machine 2. The reloading adjustment management device 6 is constituted by, for example, a microcomputer, and outputs reloading adjustment information necessary for reloading adjustment work. The worker performs the replacement adjustment work based on the output information from the replacement adjustment management device 6. The reloading adjustment management device 6 transmits reloading adjustment information to the first component replenishment management system 3 by an operation of an operator. Fig. 10 is a diagram for explaining the reloading adjustment information JH2 transmitted from the reloading adjustment management apparatus 6 and input to the first component replenishment management system 3. The reloading adjustment information JH2 may be information including element remaining amount information JH 24. As described above, the remaining component number information JH24 is information on the total remaining component number of components E stored in the component storage tape 243 wound around the reel 2420 of each of the first reel holder 2419A and the second reel holder 2419B mounted on each AF241, and is transmitted from the mounter operation management apparatus 4 in the present embodiment as the remaining component number information JH 24.

Specifically, as shown in fig. 10, replacement adjustment information JH2 is information in which substrate information JH11, carriage identification information JH21, feeder identification information JH22, reel identification information JH23, component identification information JH141, remaining component number information JH24, and remaining component number warning value information JH25 are associated with each other. The carriage identification information JH21 is information for identifying the carriage 242 in which the plurality of AFs 241 are arranged in parallel in the component supply unit 24. Feeder identification information JH22 is information for identifying AF 241. The reel identification information JH23 is information for identifying the reels 2420 of the respective reel holders of the first and second reel holders 2419A and 2419B mounted in the AF 241. The remaining component number warning value information JH25 is information indicating that the total remaining component number indicated by the remaining component number information JH24 is a predetermined value (remaining component number warning value) to which a warning should be given, before the component E stored in the component storage tape 243 wound on the reel 2420 of each of the first reel holder 2419A and the second reel holder 2419B becomes a component supply/disconnection.

The control Unit 34 of the first component replenishment management system 3 is configured by a CPU (Central Processing Unit), a ROM (Read Only Memory) storing a control program, a RAM (Random Access Memory) serving as a work area of the CPU, and the like. The control unit 34 controls the data communication unit 31, the operation unit 32, and the display unit 33 by the CPU executing a control program stored in the ROM, and generates various kinds of determination result information on reel replenishment to each of the plurality of AFs 241 provided in the component supply unit 24. As shown in fig. 8, the control unit 34 includes a communication control unit 341, an operation control unit 342, a display control unit 343, an acquisition unit 344, a setting unit 345, an element supply monitoring unit 346, a replenishment target determination unit 347, a replenishment time determination unit 348, and a recommendation start time determination unit 349.

The communication control unit 341 controls data communication with the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the replacement adjustment management apparatus 6 by the data communication unit 31. The operation control portion 342 controls the operation portion 32. The display control unit 343 controls the display operation of the information by the display unit 33.

[ control actions relating to component replenishment in first component replenishment management system ]

The configuration of the control unit 34 will be described with reference to fig. 8 and 11. Fig. 11 is a diagram for explaining a control operation of the first component replenishment management system 3. Fig. 11 shows an example of producing a mounting substrate by supplying components from 7 AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G of the plurality of AFs 241 provided in parallel on the cart 242 of each component supply section 24. Note that, it is assumed that a tape feeder other than AF241 is also provided in parallel in the component supply unit 24. As described above, the splice feeder is configured to mount 1 reel. In the splice feeder, before the component storage tape is fed out from the reel in advance and becomes disconnected, a splicing operation of connecting the tip end portion of the preceding component storage tape and the distal end portion of the succeeding component storage tape is required in order to transit from the component storage tape to the succeeding component storage tape. The AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G may be arranged in the component supply unit 24 of the same mounting machine 2, or may be arranged in the component supply units 24 of different mounting machines 2.

The acquisition unit 344 acquires a management start time TS indicating a start time of management of reel replenishment for each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G. The acquisition unit 344 may acquire the time when the production of the mounted board is started as the management start time TS, or may acquire the time when the instruction information instructing the start of the management is input as the management start time TS when the instruction information is input via the operation unit 32. In the present embodiment, the acquisition unit 344 acquires the time when the instruction information is input via the operation unit 32 as the management start time TS.

The setting unit 345 sets a specific period TW1 from the management start time TS to a specific time TT after a predetermined specific time has elapsed. The setting unit 345 sets a predetermined management period TW2 having the specific time TT as the latest time (hereinafter referred to as "latest time") within the specific period TW 1. The specific time used when the setting unit 345 sets the specific period TW1 and the time interval of the management period TW2 are input by the operator via the operation unit 32. The specific time is set to an arbitrary time such as 60 minutes, for example. The specific time may be set so that the time at which the splicing operation on the splice feeder is estimated to occur is in the vicinity of the specific time TT. In this case, the operator can perform the splicing operation to the splice feeder together with the supply operation to the reel of AF241 during the management period TW2 with reference to the specific time TT, which will be described later in detail.

The component supply monitoring unit 346 monitors the supply status of the components E in each of the plurality of AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G. The component supply monitoring unit 346 determines a resupply possible time at which a new reel can be replenished for each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G. The replenishment possible timing is a timing at which the reel 2420 on which the preceding component storage tape 243, which has previously been supplied with the component, is wound in the reels 2420 attached to the respective reel supports of the first reel support 2419A and the second reel support 2419B among the plurality of AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G becomes disconnected. When the previous reel 2420 becomes the element supply-disconnection, the new reel can be replenished.

In addition, the element supply monitoring part 346 determines the remaining number warning timing for each of the plurality of AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G. The remaining number warning timing is a timing at which the total remaining number of components of the component storage tape 243 wound on the reels 2420 of the respective reel holders mounted on the first reel holder 2419A and the second reel holder 2419B reaches a prescribed component remaining number warning value.

The component supply monitoring unit 346 determines the replenishable time and the remaining quantity warning time based on the information JH24 on the remaining quantity of components from the mounting machine operation management apparatus 4 (or the reloading adjustment management apparatus 6), the production schedule information JH1 from the production schedule management apparatus 5, and the reloading adjustment information JH2 from the reloading adjustment management apparatus 6, which are information supplied from the data communication unit 31 to the control unit 34.

Specifically, the component supply monitoring unit 346 first subtracts the remaining number of components on the reel 2420 on which the subsequent component tape 243 is wound from the total remaining number of components indicated by the remaining component number information JH24 to obtain the remaining number of components on the reel 2420 on which the preceding component tape 243 is wound. The component supply monitoring unit 346 divides the required number of components, indicated by the component required number information JH143, required for production of 1 mounted substrate, identified by the component identification information JH141, by the mounting time of the components for production of 1 mounted substrate, determined for each substrate by the substrate information JH11 indicated by the cycle time information JH144, and obtains the number of used components per 1 second. Then, the component supply monitoring unit 346 determines the replenishment available time by dividing the remaining number of components on the reel 2420 on which the preceding component storage tape 243 is wound by the number of used components per 1 second. On the other hand, the component supply monitoring unit 346 determines the remaining number warning time by dividing the number of components obtained by subtracting the component remaining number warning value indicated by the component remaining number warning value information JH25 from the total number of components remaining indicated by the component remaining number information JH24 by the number of used components per 1 second.

In addition, the total remaining number of elements represented by element remaining number information JH24 is reduced each time an element is taken out by head unit 25. When the reel 2420 on which the preceding component storing tape 243 is wound becomes a component supply break and a new reel is replenished with AF241A, 241B, 241C, 241D, 241E, 241F, 241G, the total component remaining number is updated by adding the number of components (the initially set number) stored in the component storing tape 243 wound on the new reel to the total component remaining number that changes each time a component is taken out by the head unit 25, which will be described later in detail. The number of components (initial set number) housed in the component housing tape 243 wound around the new reel is stored in the ROM or the like of the control unit 34 for each component identified by the component identification information JH 141. When a reel on which the component storage tape 243 in use is wound is replenished as a new reel, the initial set number stored in the ROM or the like of the control unit 34 is rewritten with the actual number of components stored in the component storage tape 243.

In the example shown in fig. 11, the replenishment availability time and the remaining amount warning time determined by the element supply monitoring unit 346 and associated with each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G will be described below.

A resuppliable time T1 is determined for AF 241A. The replenishment possible time T1 of the AF241A is a time earlier than the bit timing TT and earlier than the earliest time (hereinafter referred to as "earliest time") of the management period TW2, and includes a time period before the earliest time of the management period TW2 in the specific period TW 1. The remaining number warning time of the AF241A is not shown in fig. 11, and includes a time period TW3 later than the timing TT.

A resuppliable time T2 is determined for AF 241B. The replenishment possible time T2 of the AF241B is a time earlier than the bit timing TT and later than the earliest time of the management period TW2, and is included in the management period TW 2. The remaining number warning time of the AF241B is not shown in fig. 11, and includes a time period TW3 later than the timing TT.

A resuppliable time T3 is determined for AF 241C. The replenishment possible time T3 of the AF241C is a time earlier than the bit timing time TT and later than the earliest time of the management period TW2, is included in the management period TW2, and is a time later than the replenishment possible time T2 of the AF 241B. The remaining number warning time of the AF241C is not shown in fig. 11, and includes a time period TW3 later than the timing TT.

The replenishment availability time of AF241D is not shown in fig. 11. The replenishment possible time of the AF241D is a time earlier than the bit timing TT and earlier than the management start time TS, and is included in a time period before the management start time TS. The remaining number warning timing T6 is determined for AF 241D. The remaining number warning time T6 of the AF241D is a time later than the bit timing TT and includes a time period TW3 later than the bit timing TT.

A resuppliable time T4 is determined for AF 241E. The replenishment possible time T4 of the AF241E is a time later than the bit timing TT, and includes a time period TW3 later than the bit timing TT. The remaining number warning timing of AF241E is not shown in fig. 11. The remaining-amount warning time of the AF241E is a time later than the replenishable time T4 and includes a time period TW3 later than the bit timing TT.

A resuppliable time T5 is determined for AF 241F. The replenishment possible time T5 of the AF241F is a time later than the bit timing TT, and includes a time period TW3 later than the bit timing TT. The resupply possible time T5 of the AF241F is later than the resupply possible time T4 of the AF 241E. The remaining number warning timing of AF241F is not shown in fig. 11. The remaining-amount warning time of the AF241F is a time later than the replenishable time T5 and includes a time period TW3 later than the bit timing TT.

A resuppliable time T6 is determined for AF 241G. The replenishment possible time T6 of the AF241G is a time later than the bit timing TT, and includes a time period TW3 later than the bit timing TT. The resupply possible time T6 of the AF241G is later than the resupply possible time T5 of the AF 241F. The remaining number warning timing of AF241G is not shown in fig. 11. The remaining-amount warning time of the AF241G is a time later than the replenishable time T6 and includes a time period TW3 later than the bit timing TT.

Next, the replenishment target specification unit 347 specifies AF241 whose replenishment possible time is earlier than the positioning time TT as the component replenishment target device to be replenished on the new reel of the management period TW2 in the specific period TW 1. In the example shown in fig. 11, the replenishment target specification unit 347 specifies all AFs 241A, 241B, 241C, and 241D whose replenishment possible times are earlier than the bit timing TT as the element replenishment target devices.

In the first component replenishment management system 3, the replenishment target specification unit 347 sets, as the component replenishment target devices, all AFs 241A, 241B, 241C, and 241D that can replenish new reels in the management period TW3 within the specific period TW1 with reference to the specific time TT. Accordingly, the "collective replenishment" for collectively performing the replenishment work of the reels by the operator can be performed with respect to the AFs 241A, 241B, 241C, and 241D capable of replenishing new reels during the management period TW2 in the specific period TW 1. Therefore, the operator can perform "collective replenishment" of the new reel using the specific time TT as a reference of the specific period TW1 as a criterion of the work start time of the replenishment work. Therefore, the frequency of the operator going to the mounting apparatus 2 with the AF241 attached thereto can be reduced, and the load of the replenishment work performed by the operator can be reduced.

Next, the replenishment timing determination unit 348 determines the replenishment timing TH of the new reel in the management period TW2 in the same specific period TW1 for the AFs 241A, 241B, 241C, and 241D determined as the device to be replenished by the replenishment target determination unit 347. Thus, the operator can perform the replenishment work of a new reel to the AFs 241A, 241B, 241C, and 241D specified as the component replenishment target devices at the same replenishment timing TH.

More specifically, the replenishment timing determination unit 348 identifies the target device whose replenishment possible time is the time later than the earliest time of the management period TW2 among the AFs 241A, 241B, 241C, and 241D determined as the device replenishment target devices by the replenishment target determination unit 347. In the example shown in fig. 11, AF241B at a resupply possible time T2 later than the earliest time of the management period TW2 and AF241C at a resupply possible time T3 are recognized as the target devices. The replenishment timing determination unit 348 determines, as the attention replenishable time, a replenishment possible time T3 that is the latest time of the replenishment possible times T2 and T3 corresponding to the AFs 241B, 241C as the attention target devices. Then, the replenishment timing determination unit 348 determines, as the replenishment timing TH, any time between the replenishment possible time T3 and the specific time TT, which are determined as the attention replenishable time, within the specific period TW 1.

The time period between the replenishable time T3 as the noticed replenishable time and the specific time TT is a time period during which all AFs 241A, 241B, 241C, 241D specified as the component replenishment target devices by the replenishment target specifying unit 347 can be replenished with new reels, the replenishable time being a time earlier than the specific time TT. That is, the time period between the resupply possible time T3, which is the attention resupply possible time, and the specific time TT is a time period during which "collective replenishment" can be performed in which replenishment work for new reels of the AF241A, 241B, 241C, and 241D, which are the device subject to component replenishment, is concentrated. The replenishment timing determination unit 348 determines an arbitrary timing between the replenishment possible timing T3, which is the target replenishment possible timing, and the specific timing TT as the replenishment timing TH for the reels of the AFs 241A, 241B, 241C, 241D, which are the devices to be component replenished. Thus, the operator can perform the replenishing operation of the reels of the AF241A, 241B, 241C, 241D as the device to be replenished at an arbitrary replenishing timing TH between the replenishing possible time T3 as the attention replenishing possible time and the specific time TT.

In the example shown in fig. 11, the replenishment timing determination unit 348 determines a replenishment possible time T3, which is a target replenishment possible time, in the management period TW2 in the specific period TW1 as the replenishment timing TH. As described above, the time period between the resupply possible time T3, which is the attention resupply possible time, and the specific time TT is a time period during which "collective replenishment" can be performed in which replenishment work for new reels of the AF241A, 241B, 241C, and 241D, which are the device subject to component replenishment, is concentrated. The resupply possible time T3, which is the notable resupply possible time, is the earliest time in the period in which "intensive replenishment" is possible. By setting the resupply possible time T3 as the target resupply possible time as the replenishment timing TH for the reels of the AFs 241A, 241B, 241C, and 241D as the device to be replenished, the operator can perform "concentrated replenishment" with time being sufficient.

Next, the recommendation start time determination unit 349 determines the next recommendation start time TNS recommended as the start time of the next replenishment management in the time period TW3 after the bit timing TT. In the example shown in fig. 11, the recommended start time specification unit 349 specifies the start time of the next replenishment management for the remaining AFs 241E, 241F, and 241G, of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G, excluding the AFs 241A, 241B, 241C, and 241D as the device to be replenished.

The recommendation start time specification unit 349 specifies the earliest time T4 among the supplyable times T4, T5, and T6 corresponding to the AFs 241E, 241F, and 241G other than the device to be replenished as the next recommendation start time TNS. Further, recommendation start time specification unit 349 may be configured to specify specific time TT as next recommendation start time TNS. The recommendation start time determination unit 349 generates determination result information indicating a determination result of the next recommendation start time TNS. The determination result information is displayed on the display section 33 controlled by the display control section 343. The identification result information is supplied to the data communication unit 31, and is transmitted from the data communication unit 31 to the mounting machine operation management device 4, the portable terminal device carried by the operator, or the component library terminal device disposed in the component library storing the reel or the like to be mounted in the AF241 under the control of the communication control unit 341. The mounting machine operation management device 4, the portable terminal device, and the component library terminal device display the inputted determination result information. The operator can grasp the next recommended start time TNS, which is the start time of the next replenishment management, after the specific time TT by checking the determination result information displayed on the display unit 33 or the like. After grasping the next recommended start time TNS, the operator can predict the timing of the next replenishment job for the AFs 241E, 241F, 241G by adding a predetermined specific time to the next recommended start time TNS. This makes it easy for the operator to plan the replenishment work.

When the operator who grasps the next recommended start time TNS from the confirmation determination result information inputs instruction information instructing the start of management of the AFs 241E, 241F, 241G via the operation unit 32, the acquisition unit 344 acquires the time at which the instruction information is input as the management start time. When the acquisition unit 344 acquires the management start time for the AFs 241E, 241F, 241G according to the instruction information via the operation unit 32, the aforementioned operations of each of the setting unit 345, the component supply monitoring unit 346, the replenishment target determination unit 347, the replenishment time determination unit 348, and the recommendation start time determination unit 349 are repeated. The acquisition unit 344 may automatically acquire the next recommended start time TNS as a management start time for starting the supply management of the reels of the AFs 241E, 241F, and 241G. When the acquisition unit 344 automatically acquires the next recommended start time TNS as the management start time for the AFs 241E, 241F, 241G, the above-described operations of each of the setting unit 345, the component supply monitoring unit 346, the replenishment target determination unit 347, the replenishment timing determination unit 348 and the recommended start time determination unit 349 are automatically repeated.

The replenishment target specification unit 347 generates replenishment specifying result information indicating a result of specifying the component replenishment target device. The replenishment determination result information generated by the replenishment target specification unit 347 may be added with information on the replenishment time TH specified by the replenishment time specification unit 348 and information on the next recommended start time TNS specified by the recommended start time specification unit 349. Fig. 12 is a diagram for explaining replenishment determination result information JH3 generated by the replenishment target specification unit 347 of the first component replenishment management system 3.

The replenishment determination result information JH3 is information including replenishment period information JH31, replenishment quantity information JH32, and replenishment element information JH 33. The replenishment timing information JH31 is information indicating the result of determination by the replenishment timing determination unit 348 of the replenishment timing TH. The replenishment quantity information JH32 is information indicating the total number of new reels replenished to the AFs 241A, 241B, 241C, 241D as the component replenishment target devices specified by the replenishment target specification unit 347.

The replenishment-component information JH33 is information on new reels to be replenished to the AFs 241A, 241B, 241C, 241D as the component replenishment target devices specified by the replenishment-target specifying unit 347. As shown in fig. 12, the supply component information JH33 is information in which the mounter type identification information JH331, the component supply unit position information JH332, the carriage identification information JH21, the feeder identification information JH22, the component identification information JH141, and the component type identification information JH142 are associated with each other. The mounter type identification information JH331 is information for identifying the mounters 2 with the AFs 241A, 241B, 241C, and 241D. The component supply section position information JH332 is information for specifying the arrangement position of the component supply sections 24 provided with the AFs 241A, 241B, 241C, and 241D in the mounter 2.

The replenishment determination result information JH3 is displayed on the display unit 33 controlled by the display control unit 343. The replenishment confirmation result information JH3 is supplied to the data communication unit 31, and is transmitted from the data communication unit 31 to the mounting machine operation management apparatus 4 under the control of the communication control unit 341. Based on the replenishment determination result information JH3 input to the mounting machine operation management apparatus 4, the production line operator can perform the replenishment work for the reel of the AF 241.

[ Special control actions in the first element replenishment management System ]

There are sometimes the following: as shown in fig. 13, all of the resupply possible times T1, T2, and T3 of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G determined by the element supply monitoring unit 346 are times later than the bit timing time TT. In this case, the replenishment target specification unit 347 determines that there is no component replenishment target device that is a replenishment target for a new reel within the management period TW2 with reference to the specific time TT. Then, the replenishment target specification unit 347 generates "there is no element replenishment target device. "and the like as replenishment determination result information. The message information is displayed on the display unit 33 and transmitted to the mounting machine operation management apparatus 4 via the data communication unit 31. The operator of the production line can know, based on the message information, that there is no replenishment work based on the specific time TT.

In addition, there are cases where: as shown in fig. 14, there is AF241 whose remaining number warning timing determined by the component supply monitoring unit 346 is earlier than the management period TW 2. With respect to the example shown in fig. 14, the replenishment availability time and the remaining amount warning time determined by the element supply monitoring unit 346 and associated with each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G will be described below.

A resuppliable time T1 is determined for AF 241A. The replenishment possible time T1 of the AF241A is a time earlier than the bit timing time TT and earlier than the earliest time of the management period TW2, and includes a time period earlier than the earliest time of the management period TW2 in the specific period TW 1. The remaining number warning time of the AF241A is not shown in fig. 14, and includes a time period TW3 after the specific time TT.

A resuppliable time T3 is determined for AF 241B. The replenishment possible time T3 of the AF241B is a time earlier than the bit timing TT and later than the earliest time of the management period TW2, and is included in the management period TW 2. The remaining number warning time of the AF241B is not shown in fig. 14, and includes a time period TW3 later than the timing TT.

A resuppliable time T4 is determined for AF 241C. The replenishment possible time T4 of the AF241C is a time earlier than the bit timing time TT and later than the earliest time of the management period TW2, is included in the management period TW2, and is a time later than the replenishment possible time T3 of the AF 241B. The remaining number warning time of the AF241C is not shown in fig. 14, and includes a time period TW3 later than the timing TT.

The replenishable time of AF241D is not shown in fig. 14. The replenishment possible time of the AF241D is a time earlier than the bit timing TT and earlier than the management start time TS, and is included in a time period before the management start time TS. The remaining number warning timing T2 is determined for AF 241D. The remaining-amount warning time T2 of the AF241D is a time earlier than the earliest time of the management period TW 2.

A resuppliable time T5 is determined for AF 241E. The replenishment possible time T5 of the AF241E is a time later than the bit timing TT, and includes a time period TW3 later than the bit timing TT. The remaining number warning timing of AF241E is not shown in fig. 14. The remaining-amount warning time of the AF241E is a time later than the replenishable time T5 and includes a time period TW3 later than the bit timing TT.

A resuppliable time T6 is determined for AF 241F. The replenishment possible time T6 of the AF241F is a time later than the bit timing TT, and includes a time period TW3 later than the bit timing TT. The remaining number warning timing of AF241F is not shown in fig. 14. The remaining-amount warning time of the AF241F is a time later than the replenishable time T6 and includes a time period TW3 later than the bit timing TT.

A resuppliable time T7 is determined for AF 241G. The replenishment possible time T7 of the AF241G is a time later than the bit timing TT, and includes a time period TW3 later than the bit timing TT. The remaining number warning timing of AF241G is not shown in fig. 14. The remaining-amount warning time of the AF241G is a time later than the replenishable time T7 and includes a time period TW3 later than the bit timing TT.

In this way, when the remaining number warning time T2 earlier than the management time TW2 is included in the specific time period TW1, the replenishment target specification unit 347 specifies AF241A, 241B, 241C, and 241D whose replenishment possible time is earlier than the bit timing time TT as the first component replenishment target device and the second component replenishment target device separately. The replenishment target specification unit 347 specifies, as the first component replenishment target devices, the AF241A at the replenishment possible time T1 earlier than the remaining number warning time T2 and the AF241D corresponding to the remaining number warning time T2. The replenishment target specification unit 347 also specifies the AFs 241B and 241C corresponding to the replenishment possible times T3 and T4 within the management period TW2 as the second device replenishment target apparatuses.

The replenishment timing determination unit 348 determines the first replenishment timing TH1 of the new reel in the same period earlier than the remaining number warning time T2 for the AFs 241A, 241D determined as the first component replenishment target device by the replenishment target determination unit 347. Thus, the operator can perform the reel replenishment work for AFs 241A and 241D determined as the first component replenishment target devices at the same first replenishment timing TH1 at a time earlier than the remaining number warning time T2. The replenishment timing determination unit 348 also determines the second replenishment timing TH2 of the new reel in the same management period TW2 for the AFs 241B and 241C determined as the second device replenishment target apparatuses by the replenishment target determination unit 347. Thus, the operator can perform the reel replenishment work for the new reels at the same second replenishment timing TH2 for the AFs 241B, 241C determined as the second element replenishment target devices.

As shown in fig. 14, when the remaining number warning time T2 earlier than the management time TW2 is included in the specific time period TW1, the replenishment target specification unit 347 generates "a replenishment job requiring a high urgency to be performed at a time earlier than the management time period with reference to the specific time. "and the like as replenishment determination result information. The message information is displayed on the display unit 33 and transmitted to the mounting machine operation management apparatus 4 via the data communication unit 31. The operator of the production line can grasp, based on the message information, that the job of replenishment at the first replenishment period TH1 earlier than the management period TW2 is required to be performed in addition to the job of replenishment at the second replenishment period TH2 within the management period TW 2.

[ variation of control operation of first component replenishment management System ]

Fig. 15 and 16 are diagrams for explaining a first modification of the operation of determining the replenishment time by the replenishment time determination unit 348 of the first component replenishment management system 3. The replenishment timing determination unit 348 may be configured to determine the same specific time TT within the specific period TW1 as the replenishment timing TH for the AFs 241A, 241B, 241C, and 241D determined as the device replenishment target apparatuses by the replenishment target determination unit 347. When replenishment timing determination unit 348 performs an operation of determining specific time TT as replenishment timing TH, setting unit 345 may set only specific period TW1 without setting management period TW2 described above. The setting unit 345 may be configured to set the above-described management period TW2 in advance, and set the time interval of the management period TW2 to "0 (zero)" when the replenishment timing determination unit 348 performs an operation of determining the specific time point TT as the replenishment timing TH. The operator can perform the replenishing operation on the reels of the AFs 241A, 241B, 241C, and 241D as the device to be replenished with the specific time TT as a reference of the specific period TW1 as the replenishing timing TH.

In addition, when there is an AF241 capable of replenishing a new reel at the management start time TS, the replenishment timing determination unit 348 may be configured to set the replenishment timing for the new reel of the AF241 to the management start time TS. In the example shown in fig. 16, the replenishment timing determination unit 348 sets the management start time TS as the replenishment timing for the AF241D that can replenish a new reel at the management start time TS.

Fig. 17 is a diagram for explaining a second modification of the operation of determining the replenishment time by the replenishment time determination unit 348 of the first component replenishment management system 3. As described above, the replenishment timing determination unit 348 identifies the target device whose replenishment possible time is the time later than the earliest time of the management period TW2 among the AFs 241A, 241B, 241C, and 241D determined as the device replenishment target devices by the replenishment target determination unit 347. In the example shown in fig. 17, AF241B at a resupply possible time T2 later than the earliest time of the management period TW2 and AF241C at a resupply possible time T3 are recognized as the target devices. The replenishment timing determination unit 348 determines, as the attention replenishable time, a replenishment possible time T3 that is the latest time of the replenishment possible times T2 and T3 corresponding to the AFs 241B, 241C as the attention target devices. Then, the replenishment timing determination unit 348 determines, as the replenishment timing TH, any time between the replenishment possible time T3 and the specific time TT, which are determined as the attention replenishable time, within the management period TW 2. Thus, the operator can perform the replenishing operation of the reels of the AF241A, 241B, 241C, 241D as the device to be replenished at an arbitrary replenishing timing TH between the replenishing possible time T3 as the attention replenishing possible time and the specific time TT.

< second embodiment >

Fig. 18 is a block diagram showing the configuration of the component replenishment management system 3A according to the second embodiment. Hereinafter, the component replenishment management system 3A according to the second embodiment will be referred to as a "second component replenishment management system 3A". The second component replenishment management system 3A is connected to the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the replacement-installation adjustment management apparatus 6 so as to be capable of data communication, in the same manner as the first component replenishment management system 3 described above. The second component replenishment management system 3A includes, for example, a microcomputer, and as shown in fig. 18, includes a data communication unit 31A, an operation unit 32A, a display unit 33A, and a control unit 34A.

The data communication unit 31A, the operation unit 32A, and the display unit 33A of the second component replenishment management system 3A are configured similarly to the data communication unit 31, the operation unit 32, and the display unit 33 of the first component replenishment management system 3, and therefore, the description thereof is omitted.

The control unit 34A of the second component replenishment management system 3A is configured by a CPU, a ROM storing a control program, a RAM used as a work area of the CPU, and the like. The control unit 34A controls the data communication unit 31A, the operation unit 32A, and the display unit 33A by the CPU executing the control program stored in the ROM, and generates various kinds of determination result information on reel replenishment to each of the plurality of AFs 241 provided in the component supply unit 24. As shown in fig. 18, the control unit 34A includes a communication control unit 341A, an operation control unit 342A, a display control unit 343A, an acquisition unit 344A, a setting unit 345A, an element supply monitoring unit 346A, a replenishment target determination unit 347A, a replenishment timing determination unit 348A, and an adjustment unit 349A.

The communication control unit 341A controls data communication with the mounting machine operation management apparatus 4, the production schedule management apparatus 5, and the replacement adjustment management apparatus 6 by the data communication unit 31A. The operation control portion 342A controls the operation portion 32A. The display control unit 343A controls the display operation of the information by the display unit 33A.

[ control actions relating to component replenishment in second component replenishment management System ]

The configuration of the control unit 34A will be described with reference to fig. 18 and 19. Fig. 19 is a diagram for explaining a control operation of the second component replenishment management system 3A. Fig. 19 shows an example of producing a mounting substrate by supplying components from 7 AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G of the plurality of AFs 241 provided in parallel on the cart 242 of each component supply section 24. Note that, it is assumed that a tape feeder other than AF241 is also provided in parallel in the component supply unit 24. The AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G may be arranged in the component supply unit 24 of the same mounting machine 2, or may be arranged in the component supply units 24 of different mounting machines 2.

The acquisition unit 344A acquires a management start time TS indicating a start time of management of reel replenishment for each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G.

The setting unit 345A sets a target period TW0 for replenishment management of a new reel to each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G later than the management start time TS. The target period TW0 is a period based on, for example, the total production time required for production of 1 substrate type in production of the mounted substrate by the mounting apparatus 2, the total production time required for production of 1 production lot of 1 substrate type, and the like, and the operator inputs the target period TW0 via the operation unit 32A. The setting unit 345A divides the target period TW0 into a plurality of specific periods TW11, TW12, TW13, TW14, and TW15 at predetermined specific time intervals. The specific time defining the time interval of each specific period TW11, TW12, TW13, TW14, and TW15 is input by the operator via the operation unit 32A, and is set to an arbitrary time such as 60 minutes, for example. Hereinafter, the first specific period TW11, the second specific period TW12, the third specific period TW13, the fourth specific period TW14, and the fifth specific period TW15 are referred to in chronological order from the beginning to the end. In the present embodiment, the setting unit 345A sets the time intervals of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 to be constant.

Then, the setting unit 345A sets predetermined management periods TW21, TW22, TW23, TW24, and TW25 for each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15. Each of the management periods TW21, TW22, TW23, TW24, and TW25 is a period in which the latest specific time TT1, TT2, TT3, TT4, and TT5 of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 are the latest time. The time intervals of the management periods TW21, TW22, TW23, TW24, and TW25 are input by the operator via the operation unit 32. Hereinafter, the management period TW21 corresponding to the first specific period TW11 is referred to as a "first management period TW 21", and the specific time point TT1 is referred to as a "first specific time point TT 1". Similarly, the second to fifth specific periods TW22, TW23, TW24, TW25 are referred to as second to fifth management periods TW12, TW13, TW14, TW15, and are referred to as second to fifth specific times TT2, TT3, TT4, TT 5.

The component supply monitoring unit 346A monitors the supply status of the components E in each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, 241G. The component supply monitoring unit 346A determines a resupply possible time and a remaining number warning time at which a new reel can be replenished for each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G. The component supply monitoring unit 346A determines the replenishment possible time and the remaining quantity warning time based on the component remaining quantity information JH24 from the mounting machine operation management apparatus 4 (or the replacement adjustment management apparatus 6), the production plan information JH1 from the production plan management apparatus 5, and the replacement adjustment information JH2 from the replacement adjustment management apparatus 6, which are information provided from the data communication unit 31A to the control unit 34A. The specific determination method of the replenishment availability time and the remaining amount warning time by the component supply monitoring unit 346A using the remaining amount information JH24 and the like is the same as that of the component supply monitoring unit 346 described above.

When the replenishment timing determination unit 348A, which will be described later, determines the replenishment timing for each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G for a new reel, the component supply monitoring unit 346A determines the replenishment possible timing and the remaining number warning timing as described below. That is, when the replenishment timing is determined within a certain period, the component supply monitoring unit 346A determines replenishment possible timings and remaining quantity warning timings for other certain periods later in time series than the certain period, as if a new reel is replenished at the replenishment timing. More specifically, when determining the replenishment possible time and the remaining number warning time using the total remaining number of components indicated by the remaining number of components information JH24, the component supply monitoring unit 346A updates the total remaining number of components according to the replenishment timing. For example, when the replenishment period is determined in the first specific period TW11, the component supply monitoring unit 346A assumes that a new reel is replenished at the replenishment period. Then, the component supply monitoring unit 346A updates the total component remaining number by adding the number of components (initial set number) stored in the component storage tape 243 wound on the new reel to the total component remaining number. The element supply monitoring unit 346A uses the updated total remaining number of elements to determine the replenishment possible time and the remaining number warning time for the second to fifth specific periods TW12, TW13, TW14, and TW15 that are later in time series than the first specific period TW 11.

In the example shown in fig. 19, the replenishment availability time and the remaining amount warning time determined by the element supply monitoring unit 346A and associated with each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G will be described below.

A resuppliable time T1 is determined for AF 241A. The replenishment possible time T1 of the AF241A is a time included in the first specific period TW11, which is earlier than the first specific time TT1 and earlier than the earliest time of the first management period TW 21. Further, it is considered that a new reel is replenished at the first replenishment timing TH1 within the first specific period TW11 specified by the replenishment timing specifying unit 348A described later, and the second replenishment possible time T8 is specified for AF 241A. The second resupply time T8 of the AF241A is a time included in the fifth specific period TW15 and earlier than the fifth specific time TT5 and earlier than the earliest time of the fifth management period TW 25.

The replenishment possible time T2 of the AF241B is included in the first management period TW21 of the first specific period TW11, and is a time earlier than the first specific time TT1 and later than the earliest time of the first management period TW 21. Further, it is considered that a new reel is replenished at the first replenishment timing TH1 within the first specific period TW11 specified by the replenishment timing specifying unit 348A described later, and the second replenishment possible time T9 is specified for AF 241B. The second resupply time T9 of the AF241B is included in the fifth management period TW25 of the fifth specific period TW15, and is a time earlier than the fifth specific time TT5 and later than the earliest time of the fifth management period TW 25. The remaining number warning timing of AF241B is not shown in fig. 19 and is included in a later period than the fifth specific timing TT 5.

A resuppliable time T3 is determined for AF 241C. The replenishment possible time T3 of the AF241C is included in the first management period TW21 of the first specific period TW11, and is a time earlier than the first specific time TT1 and later than the earliest time of the first management period TW 21. The resupply possible time T3 of the AF241C is later than the resupply possible time T2 of the AF 241B. The remaining number warning timing of AF241C is not shown in fig. 19 and is included in a later period than the fifth specific timing TT 5.

The replenishment availability time of AF241D is not shown in fig. 19. The replenishment possible time of the AF241D is a time earlier than the first specific time TT1 of the first specific period TW11 and earlier than the management start time TS, and is included in a period before the management start time TS. Further, it is considered that a new reel is replenished at the first replenishment timing TH1 within the first specific period TW11 specified by the replenishment timing specifying unit 348A described later, and the second replenishment possible time T7 is specified for AF 241D. The second resupply time T7 of the AF241D is a time included in the fourth specific period TW14 and earlier than the fourth specific time TT4 and earlier than the earliest time of the fourth management period TW 24. Also, the remaining number warning timing T10 is determined for the AF 241D. The remaining-amount warning time T10 of the AF241D is included in the fifth management period TW25 of the fifth specific period TW15, and is a time earlier than the fifth specific time TT5 and later than the earliest time of the fifth management period TW 25.

A resuppliable time T4 is determined for AF 241E. The replenishment possible time T4 of the AF241E is a time included in the third specific period TW13, which is earlier than the third specific time TT3 and earlier than the earliest time of the third management period TW 23. The remaining number warning timing of AF241E is not shown in fig. 19 and is included in a later period than the fifth specific timing TT 5.

A resuppliable time T5 is determined for AF 241F. The replenishment possible time T5 of the AF241F is a time included in the third specific period TW13, which is earlier than the third specific time TT3 and earlier than the earliest time of the third management period TW 23. The remaining number warning timing of AF241F is not shown in fig. 19 and is included in a later period than the fifth specific timing TT 5.

A resuppliable time T6 is determined for AF 241G. The replenishment possible time T6 of the AF241G is included in the third management period TW23 of the third specific period TW13, and is a time earlier than the third specific time TT3 and later than the earliest time of the third management period TW 23. The remaining number warning timing of AF241G is not shown in fig. 19 and is included in a later period than the fifth specific timing TT 5.

Next, the replenishment target specification unit 347A specifies the component replenishment target device that is the replenishment target of the new reel for each of the first to fifth management periods TW21, TW22, TW23, TW24, and TW25 of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15. The replenishment target specification unit 347A specifies, as the element replenishment target device, all AFs 241 whose replenishment possible times are earlier than the first to fifth specific times TT1, TT2, TT3, TT4, and TT5 for each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

In the example shown in fig. 19, the replenishment target specification unit 347A specifies, for the first specific period TW11, all of the AFs 241A, 241B, 241C, and 241D whose replenishment possible times are earlier than the first specific time TT1 as the component replenishment target devices to be replenished from the new reel in the first management period TW 21. In the second specific period TW12, since there is no AF241 whose replenishment possible time is earlier than the second specific time TT2, the replenishment target specification unit 347A determines that there is no component replenishment target device to be replenished as a new reel in the second management period TW 22.

In the third specific period TW13, the replenishment target specification unit 347A specifies all of the AFs 241E, 241F, and 241G whose replenishment possible times are earlier than the third specific time TT3 as the component replenishment target devices to be replenished by the new reel in the third management period TW 23. In the fourth specific period TW14, the replenishment target specification unit 347A specifies all AFs 241D whose replenishment possible times are earlier than the fourth specific time TT4 as the component replenishment target devices to be replenished by new reels in the fourth management period TW 24. In the fifth specific period TW15, the replenishment target specification unit 347A specifies all AFs 241A and 241B whose replenishment possible times are earlier than the fifth specific time TT5 as the component replenishment target devices to be replenished by new reels in the fifth management period TW 25.

In the second component replenishment management system 3A, the replenishment target specifying unit 347A specifies the component replenishment target device that is the replenishment target of the new reel for each of the first to fifth management periods TW21, TW22, TW23, TW24, and TW25 of the plurality of first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 that are divided at time intervals of the predetermined specific time. Accordingly, the AF241 capable of supplying the reel during the first to fifth management periods TW21, TW22, TW23, TW24, and TW25 of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 can be "collectively supplied" in which the supply work of the reel by the operator is collectively performed. Therefore, the load of the replenishment work by the operator can be reduced. Since the time intervals of the specific periods TW11, TW12, TW13, TW14, and TW15 are set to be constant by the setting unit 345A, the operator can periodically perform the operation of replenishing the reel of the component replenishment target device at constant time intervals.

Next, the replenishment timing determination unit 348A determines the replenishment timing of the same new reel for the AF241 determined as the component replenishment target device by the replenishment target determination unit 347A for each of the first to fifth management periods TW21, TW22, TW23, TW24, and TW25 of the first to fifth management periods TW21, TW22, TW23, TW24, and TW 25. The replenishment timing determination unit 348A determines the replenishment timing for each of the first to fifth management periods TW21, TW22, TW23, TW24, and TW25 in the same manner as the replenishment timing determination unit 348 described above.

In the example shown in fig. 19, replenishment period determination unit 348A determines as the replenishment period any time point within first to fifth management periods TW21, TW22, TW23, TW24, and TW25 of first to fifth management periods TW21, TW22, TW23, TW24, and TW25, respectively. The replenishment timing determination unit 348A determines the first replenishment timing TH1 for the AFs 241A, 241B, 241C, 241D as the device to be replenished as the replenishment timing in the first management period TW21 of the first specific period TW 11. The replenishment timing determination unit 348A determines that there is no device to be replenished corresponding to the second specific period TW12, based on the determination result obtained by the replenishment target determination unit 347A, that the replenishment timing is not determined in the second management period TW 22. The replenishment timing determination unit 348A determines the second replenishment timing TH2 for the AFs 241E, 241F, and 241G as the device to be replenished as the replenishment timing in the third management period TW23 of the third specific period TW 13. The replenishment timing determination unit 348A determines the third replenishment timing TH3 for the AF241D as the device to be replenished as the replenishment timing in the fourth management period TW24 of the fourth specific period TW 14. The replenishment timing determination unit 348A determines the fourth replenishment timing TH4 for the AFs 241A, 241B as the device to be replenished as the replenishment timing in the fifth management period TW25 of the fifth specific period TW 15.

[ variation of control operation of second element replenishment management System ]

Fig. 20 is a diagram for explaining a first modification of the control operation of the second component replenishment management system 3A. The replenishment timing determination unit 348A of the second component replenishment management system 3A may be configured to determine the first to fifth specific time points TT1, TT2, TT3, TT4, TT5 in the first to fifth specific time periods TW11, TW12, TW13, TW14, TW15 as the replenishment timing. When replenishment timing determination unit 348A performs an operation of determining specific times TT1, TT2, TT3, TT4, and TT5 as replenishment timings, setting unit 345A may set only first to fifth specific periods TW11, TW12, TW13, TW14, and TW15, without setting management periods TW21, TW22, TW23, TW24, and TW25 described above. The setting unit 345A may be configured to set the above-described management periods TW21, TW22, TW23, TW24, and TW25 in advance, and set the time intervals of the management periods TW21, TW22, TW23, TW24, and TW25 to "0 (zero)" when the replenishment period determination unit 348A performs an operation of determining the specific times TT1, TT2, TT3, TT4, and TT5 as replenishment periods. The operator can perform the replenishment work for the reel of the component replenishment target device with the first to fifth specific time points TT1, TT2, TT3, TT4, TT5 as replenishment timings, which are references of the first to fifth specific time periods TW11, TW12, TW13, TW14, and TW 15.

In the example shown in fig. 20, the replenishment timing determination unit 348A sets the first specific time TT1 as the first replenishment timing TH1 for the AFs 241A, 241B, 241C, 241D as the device to be replenished in the first specific period TW 11. The replenishment timing determination unit 348A determines that there is no device to be replenished corresponding to the second specific period TW12, based on the determination result obtained by the replenishment target determination unit 347A, that the replenishment timing is not determined in the second specific period TW 12. The replenishment timing determination unit 348A sets the third specific time TT3 as the second replenishment timing TH2 for the AFs 241E, 241F, and 241G as the device to be replenished in the third specific period TW 13. The replenishment timing determination unit 348A sets the fourth specific time TT4 as the third replenishment timing TH3 for the AF241D as the device to be replenished in the fourth specific period TW 14. The replenishment timing determination unit 348A sets the fifth specific time TT5 as a fourth replenishment timing TH4 for the AFs 241A and 241B as the device to be replenished in the fifth specific period TW 15.

Fig. 21 is a diagram for explaining a second modification of the control operation of the second element replenishment management system 3A. The operation unit 32A of the second element replenishment management system 3A may be configured to receive an input operation of command information related to setting of the time interval of each specific period, which is used when the setting unit 345A divides the target period TW0 into a plurality of specific periods. In this case, the time intervals of the specific periods may be the same or different.

The setting unit 345A sets a target period TW0 for replenishment management of a new reel to each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G later than the management start time TS. The setting unit 345A sets the time interval of each of the plurality of specific periods based on the instruction information about the setting of the time interval of the specific period input via the operation unit 32A. In the example shown in fig. 21, the time intervals of the respective specific periods TW11, TW12, and TW13 are set to be different. The setting unit 345A divides the target period TW0 into a plurality of first to third specific periods TW11, TW12, and TW13 at set time intervals. Then, the setting unit 345A sets the first to third management periods TW21, TW22, and TW23 for each of the first to third specific periods TW11, TW12, and TW 13.

When the setting unit 345A sets the first to third management periods TW21, TW22, and TW23, the component supply monitoring unit 346A determines a replenishment possible time and a remaining number warning time at which a new reel can be replenished for each of the AFs 241A, 241B, 241C, 241D, 241E, 241F, and 241G. Next, the replenishment target specification unit 347A specifies the component replenishment target device to be replenished on the new reel for each of the first to third management periods TW21, TW22, and TW 23. Then, the replenishment timing determination unit 348A determines the replenishment timing of the same new reel for each of the first to third management periods TW21, TW22, and TW23 with respect to the AF241 determined as the component replenishment target device by the replenishment target determination unit 347A.

As described above, the operator can specify the time intervals of the specific periods of the first to third specific periods TW11, TW12, and TW13 via the operation unit 32A.

In the example shown in fig. 19 to 21, the setting unit 345A performs the operation of dividing the entire period of the target period TW0 into a plurality of specific periods at the management start time TS, but may be configured to automatically perform the operation of sequentially setting the specific periods in the middle of the target period TW 0. For example, the setting unit 345A may be configured to sequentially set the next specific period for each specific time that is the latest time of the specific period.

In the second component replenishment management system 3A, the replenishment target specification unit 347A generates replenishment specification result information indicating the specification result of the component replenishment target device for each of the plurality of specific periods. The replenishment-target specifying unit 347A may add information on the replenishment timing specified by the replenishment-timing specifying unit 348A to the replenishment-determination-result information generated. Fig. 22 is a diagram for explaining replenishment determination result information JH4 generated by the replenishment target determination unit 347A of the second component replenishment management system 3A.

Replenishment determination result information JH4 is information including replenishment period information JH41, replenishment quantity information JH42, feeder identification information JH22, component identification information JH141, and component type identification information JH 142. The replenishment timing information JH41 is information indicating the replenishment timing for each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 specified by the replenishment timing specification unit 348A. The replenishment quantity information JH42 is information indicating the total number of new reels replenished to the AF241, which is the component replenishment target device specified by the replenishment target specification unit 347A, for each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

Feeder identification information JH22, component identification information JH141, and component type identification information JH142 indicate information on a new reel to be replenished to AF241, which is the component replenishment target device specified by replenishment target specification unit 347A, for each of first to fifth specified periods TW11, TW12, TW13, TW14, and TW 15.

The replenishment determination result information JH4 is displayed on the display unit 33A controlled by the display control unit 343A. The replenishment confirmation result information JH4 is supplied to the data communication unit 31A, and is transmitted from the data communication unit 31A to the mounting machine operation management apparatus 4 under the control of the communication control unit 341A. Based on the replenishment determination result information JH4 input to the mounting machine operation management apparatus 4, the production line operator can perform the replenishment work for the reel of the AF 241. Note that replenishment confirmation result information JH4 of the example shown in fig. 22 displayed on display unit 33A or the like is confirmation result information when setting unit 345A divides the entire period of target period TW0 into a plurality of specific periods at management start time TS, and executes the above-described operations of element supply monitoring unit 346A, replenishment target confirmation unit 347A, and replenishment timing confirmation unit 348A in accordance with the divided periods. After the replenishment confirmation result information JH4 is displayed on the display unit 33A or the like, the setting unit 345A may set a next specific period in sequence for each specific time that is the latest time of the specific period in the middle of the target period TW0, for example, and may sequentially perform the above-described operations of the element supply monitoring unit 346A, the replenishment target specifying unit 347A, and the replenishment timing specifying unit 348A in accordance with the set specific period, and the confirmation result information for each operation may be sequentially displayed on the display unit 33A or the like. In addition, there are also cases where: after the replenishment determination result information JH4 is displayed on the display unit 33A or the like, the supply status of the elements in the element supply device monitored by the element supply monitoring unit 346A changes, and the determination results of the replenishment target determination unit 347A and the replenishment time determination unit 348A change accordingly. In this case, the above-described operations of the component supply monitoring unit 346A, the replenishment target specifying unit 347A, and the replenishment time specifying unit 348A may be executed during the target period TW0, for example, at the specific time or the like which is the latest time of the specific period, and replenishment confirmation result information updated in accordance with the execution of the operations may be displayed on the display unit 33A or the like.

The second element replenishment management system 3A according to the present embodiment may be configured to include an adjustment unit 349A as shown in fig. 18. The adjusting unit 349A performs the replenishment quantity adjusting process of adjusting the quantity of the device replenishment target apparatuses in each of the plurality of specific periods determined by the replenishment target determining unit 347A. The operation of the adjusting unit 349A will be described with reference to fig. 23. Fig. 23 is a diagram for explaining an operation of the adjusting unit 349A of the second element replenishment management system 3A.

The replenishment amount adjustment process by the adjustment unit 349A will be described assuming that the replenishment target specification unit 347A specifies the element replenishment target device for each of the plurality of specific periods as in the example shown in fig. 19 described above before the replenishment amount adjustment process is performed by the adjustment unit 349A. The adjusting unit 349A first calculates the number of the element replenishment target devices determined by the replenishment target determining unit 347A for each of the plurality of first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

In the example shown in fig. 19, the replenishment target specification unit 347A specifies the 4 AFs 241A, 241B, 241C, and 241D as the device to be replenished in the first management period TW21 of the first specific period TW 11. Therefore, the adjustment unit 349A calculates "4" as the number of the element replenishment target devices of the first specific period TW 11. The replenishment target specification unit 347A determines that there is no device to be replenished in the second management period TW22 of the second specific period TW 12. Therefore, the adjusting unit 349A calculates "0 (zero)" as the number of the element replenishment target devices of the second specific period TW 12. The replenishment target specification unit 347A specifies the 3 AFs 241E, 241F, and 241G as the element replenishment target devices in the third management period TW23 of the third specific period TW 13. Therefore, the adjustment unit 349A calculates "3" as the number of the element replenishment target devices of the third specific period TW 13. The replenishment target specification unit 347A specifies 1 AF241D as the device to be replenished in the fourth management period TW24 of the fourth specific period TW 14. Therefore, the adjustment unit 349A calculates "1" as the number of the element replenishment target devices of the fourth specific period TW 14. The replenishment target specification unit 347A specifies the 2 AFs 241A, 241B as the device to be replenished during the fifth management period TW25 of the fifth specific period TW 15. Therefore, the adjustment unit 349A calculates "2" as the number of the element replenishment target devices of the fifth specific period TW 15.

The adjusting unit 349A performs replenishment quantity adjusting processing for adjusting the quantity of the device to be replenished in each of the plurality of first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 based on the calculation result. In the replenishment quantity adjustment processing, the adjustment unit 349A compares the quantity of the device to be replenished in each of the specific periods adjacent in time series. More specifically, adjusting unit 349A compares the number of device replenishment target apparatuses between first specific period TW11 and second specific period TW12, between second specific period TW12 and third specific period TW13, between third specific period TW13 and fourth specific period TW14, and between fourth specific period TW14 and fifth specific period TW15, which are adjacent in time series.

Then, the adjusting unit 349A performs the replenishment quantity adjustment processing of the component replenishment device that allocates a part of the component replenishment device in the first notable specific period as the replenishment target for the new reel in the second notable specific period, when the number of the component replenishment devices is larger than the predetermined reference number in the first notable specific period earlier in the time series order and the number of the component replenishment devices is smaller than the reference number in the second notable specific period later in the time series order by comparing the numbers of the component replenishment devices. The predetermined reference number is, for example, an average value of the total number of the element replenishment target devices in each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15. The adjusting unit 349A does not perform the replenishment quantity adjusting process when the remaining quantity warning time is included in a third observation specific period adjacent to the second observation specific period on a later side in the time series from among the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

The replenishment amount adjustment process by the adjustment unit 349A is specifically described below with reference to fig. 19 and 23.

The adjusting unit 349A compares the number of the element replenishment target devices between the first specific period TW11 and the second specific period TW12 adjacent in time series. The device to be replenished during the first specific period TW11 (first target specific period) that is earlier in the time series is AF241A, 241B, 241C, and 241D, and the number thereof is "4" which is greater than a predetermined reference number (for example, the average value is 2). On the other hand, the number of device replenishment target devices in the second specific period TW12 (second attention specific period) that is later in the time series is "0" which is less than the predetermined reference number (for example, the average value is 2) (see fig. 19). In this case, the adjusting unit 349A allocates a part of the device to be replenished (2 AF241A and 241B) in the first specific period TW11 (the first target specific period) as the device to be replenished of a new reel in the second specific period TW12 (the second target specific period) (see fig. 23). Thus, the load of the replenishment work for the reel of the component replenishment target device specified by the replenishment target specifying unit 347A is balanced for each of the plurality of first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

The adjustment unit 349A compares the number of the device replenishment target apparatuses between the second specific period TW12 and the third specific period TW13 that are adjacent in time series. The number of device replenishment target devices in the second specific period TW12 (first attention specific period) that is earlier in the time series is "0" which is less than a predetermined reference number (for example, the average value is 2). On the other hand, the device to be replenished during the third specific period TW13 (second attention specific period) that is later in time series is AF241E, 241F, 241G, and the number thereof is "3" which is greater than a predetermined reference number (for example, the average value is 2) (see fig. 19). In this case, the adjusting unit 349A does not perform the replenishment quantity adjusting process.

The adjusting unit 349A compares the number of the element replenishment target devices between the third specific period TW13 and the fourth specific period TW14 adjacent in time series. The device to be replenished during the third specific period TW13 (the first attention specific period) that is earlier in the time series is AF241E, 241F, 241G, and the number thereof is "3" which is greater than a predetermined reference number (for example, the average value is 2). On the other hand, the device to be replenished in the fourth specific period TW14 (second attention specific period) that is later in time series is AF241D, and the number thereof is "1" that is less than the predetermined reference number (for example, the average value is 2). However, the remaining number of warning times T10 is included in a fifth specific period TW15 (third target specific period) adjacent to the fourth specific period TW14 (second target specific period) on the later side in the time series. In this case, the adjusting unit 349A does not perform the replenishment quantity adjusting process.

In the replenishing operation of the device to be replenished with elements during the fourth specific period TW14 (second attention specific period), the replenishing operation performed on AF241D including the remaining number of warning times T10 during the fifth specific period TW15 (third attention specific period) adjacent to the fourth specific period TW14 on the later side in time series is required to be a highly urgent operation. In this way, if the surplus warning time T10 is included in the fifth specific period TW15 (the third target specific period) and it is expected that the replenishment operation in the fourth specific period TW14 (the second target specific period) will be a highly urgent operation, the adjustment unit 349A does not perform the replenishment quantity adjustment process. Thus, a part of the device to be replenished during the third specific period TW13 (the first target specific period) is not allocated to the fourth specific period TW14 (the second target specific period). Therefore, the operator can perform the replenishment work with high urgency mainly in the fourth specific period TW14 (the second attention specific period).

The adjusting unit 349A compares the number of the element replenishment target devices between the fourth specific period TW14 and the fifth specific period TW15 adjacent in time series. The element replenishment target device in the fourth specific period TW14 (first attention specific period) that is earlier in time series is AF241D, and the number thereof is "1" which is less than a predetermined reference number (for example, the average value is 2). On the other hand, the device to be replenished during a fifth specific period TW15 (second attention specific period) that is later in time series is AF241A, 241B, and the number thereof is "2" which is the same as the predetermined reference number (for example, the average value is 2). In this case, the adjusting unit 349A does not perform the replenishment quantity adjusting process.

In the second component replenishment management system 3A, the adjustment unit 349A generates adjustment result information indicating the adjustment result of the number of component replenishment target devices for each of the plurality of specific periods. Fig. 24 is a diagram for explaining adjustment result information JH5 generated by adjustment unit 349A.

Adjustment result information JH5 is information including replenishment timing information JH51, replenishment quantity information JH52, feeder identification information JH22, component identification information JH141, and component type identification information JH 142. The replenishment timing information JH51 is information indicating the replenishment timing for each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW15 determined by the replenishment timing determination unit 348A after the replenishment quantity adjustment process by the adjustment unit 349A. The replenishment quantity information JH52 is information indicating the total number of new reels replenished to the AF241 after the replenishment quantity adjustment processing by the adjustment unit 349A for each of the first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

Feeder identification information JH22, component identification information JH141, and component type identification information JH142 indicate information on a new reel to be replenished to AF241 after the replenishment quantity adjustment processing by adjustment unit 349A for each of first to fifth specific periods TW11, TW12, TW13, TW14, and TW 15.

The adjustment result information JH5 is displayed on the display unit 33A controlled by the display control unit 343A. The adjustment result information JH5 is supplied to the data communication unit 31A, and is transmitted from the data communication unit 31A to the mounting machine operation management apparatus 4 under the control of the communication control unit 341A. Based on the adjustment result information JH5 input to the mounting machine operation management device 4, the production line operator can perform the operation of replenishing the reel of the AF 241.

The component replenishment management system and the component mounting system according to the embodiment of the present invention have been described above, but the present invention is not limited to this, and for example, the following modified embodiment can be adopted.

In the above-described embodiment, the AF241 configured by the tape feeder capable of mounting the reel 2420 on which the component storing tape 243 is wound has been described as the component supplying apparatus attached to the mounting machine 2, but the present invention is not limited to such a configuration. The component supplying apparatus may be any apparatus as long as it can mount a plurality of component housing members housing components, and may be, for example, a tray feeder (tray feeder) to which a plurality of trays (pallet) each including a tray (tray) on which components are placed can be mounted, or a rod feeder (stick feeder) to which a plurality of rods housing components can be mounted.

< first modified embodiment >

Fig. 25 is a diagram showing a tray feeder 1000 as a component supply device according to a first modification. The tray feeder 1000 is provided to the component supply section 24 of the mounter 2. A plurality of tray feeders 1000 may be provided in parallel in the component supply section 24. The tray feeder 1000 is configured to be able to supply components while holding the components on the tray 1004. At least one tray TR holding a plurality of components is placed on the tray 1004. The tray TR has a rectangular shape in a plan view, and a plurality of component accommodation portions are provided in a matrix on an upper surface thereof. The element receiving portions receive elements at equal intervals. The plurality of trays 1004 configured in this manner are stored in each of the first magazine 1003A and the second magazine 1003B.

The first magazine 1003A and the second magazine 1003B function as component housing members that house a plurality of trays 1004 on which trays TR holding components are placed. The first bin 1003A and the second bin 1003B are independently movable in the vertical direction in the housing 1001. The tray 1004 accommodated in the first magazine 1003A and the second magazine 1003B is moved to a table 1002 provided to protrude outward from the cover 1001 when producing the mounted substrate, thereby supplying components while being held on the tray 1004.

In the production of the mounted substrate, even if the components held in the tray 1004 stored in the first magazine 1003A are disconnected, the components are supplied while being held in the tray 1004 by moving the tray 1004 stored in the second magazine 1003B to the table 1002. At this time, during production of the mounted substrate, the operator can take out the first magazine 1003A, which is a component break, from the cover 1001 and can supply the tray feeder 1000 with a new magazine. Here, the management of replenishment of a new magazine of the tray feeder 1000 is performed by the first component replenishment management system 3 or the second component replenishment management system 3A. The replenishment management by the first component replenishment management system 3 will be described below.

In the first component replenishment management system 3, the replenishment target specification unit 347 specifies, as the component replenishment target devices, all of the tray feeders 1000 capable of performing replenishment of new magazines within the management period set by the setting unit 345 with reference to the specific time. Thus, the tray feeder 1000, which can replenish a new magazine during a management period, can perform "concentrated replenishment" in which the replenishment work of the magazines by the operator is concentrated. Therefore, the operator can perform "collective replenishment" of the new magazine with the specific time as a reference of the management period as a criterion of the work start time of the replenishment work. Therefore, the load of the replenishment work by the operator can be reduced.

The replenishment timing determination unit 348 determines a replenishment timing of a new magazine in the same management period for the tray feeder 1000 determined by the replenishment target determination unit 347 as the component replenishment target device. This allows the operator to perform a new magazine replenishment operation at the same replenishment timing with respect to the tray feeder 1000 identified as the component replenishment target device.

< second modified embodiment >

Fig. 26 is a diagram showing a tray feeder 2000 as a component supply device according to a second modification. Tray feeder 2000 is provided to component supply section 24 of mounter 2. A plurality of tray feeders 2000 may be provided in parallel in the component supply section 24. The tray feeder 2000 is configured such that 1 magazine 2003 is movable in the up-down direction within the cover body 2001. The magazine 2003 accommodates a plurality of first trays 2004, a plurality of second trays 2005, and a plurality of third trays 2006.

At least one first tray TR1 holding a plurality of components is placed on each first tray 2004. The elements held in the first tray TR1 are the same kind of elements in each first tray 2004. Similarly, at least one second tray TR2 holding a plurality of components is placed on each second tray 2005. The elements held in the second tray TR2 are the same kind of elements in each second tray 2005. However, the types of the components held in the second tray TR2 are different from the types of the components held in the first tray TR 1. In each third tray 2006, at least one third tray TR3 holding a plurality of elements is placed. The components held in the third tray TR3 are of the same kind in each third tray 2006. However, the types of components held in the third tray TR3 are different from the types of components held in the first tray TR1 and the second tray TR2, respectively.

The first tray 2004, the second tray 2005, and the third tray 2006 each have a function as a component storage member that places trays TR1, TR2, and TR3 holding a plurality of components thereon. Each of the first tray 2004, the second tray 2005, and the third tray 2006 housed in the magazine 2003 moves to a stage 2002 provided to protrude outward from the cover body 2001 when producing the mounted substrates, thereby supplying the components in a state of being held in trays TR1, TR2, and TR 3.

In the production of the mounted substrate, even if the component held on the first tray TR1 placed on one first tray 2004 among the plurality of first trays 2004 becomes disconnected, the other first trays 2004 are moved to the stage 2002, and the component is supplied while being held on the first tray TR 1. At this time, during production of the mounted substrate, the operator can take out the first tray 2004 that has been disconnected by the component feeder from the cover body 2001 and supply a new first tray to the tray feeder 2000. Similarly, in the production of the mounted substrates, even if the components held in the second tray TR2 placed on one second tray 2005 of the plurality of second trays 2005 are disconnected, the other second trays 2005 are moved to the stage 2002, and the components are supplied while being held in the second tray TR 2. At this time, during production of the mounted substrate, the worker can take out the second tray 2005 to be the component cut from the cover 2001 and supply a new second tray to the tray feeder 2000. In the production of the mounting substrate, even if the component held in the third tray TR3 placed on one third tray 2006 among the plurality of third trays 2006 is disconnected, the other third tray 2006 is moved to the stage 2002, and the component is supplied while being held in the third tray TR 3. At this time, during production of the mounted substrate, the operator can take out the third tray 2006 that has been disconnected by the component feeder from the cover 2001 and can supply a new third tray to the tray feeder 2000.

In addition, in tray feeder 2000, the number of first trays 2004, second trays 2005, and third trays 2006 may be different from each other. In such a case, the number of supplies for a new tray filled with the same components differs among the respective trays of the first tray, the second tray, and the third tray. Further, the number of components to be replenished in the tray may be changed depending on the total remaining number of components of the component type corresponding to the tray when a new tray is replenished.

Here, the management of replenishment of new trays to the tray feeder 2000 is performed by the first component replenishment management system 3 or the second component replenishment management system 3A. The replenishment management by the first component replenishment management system 3 will be described below.

In the first component replenishment management system 3, the replenishment target specification unit 347 specifies, as the component replenishment target devices, all tray feeders 2000 capable of performing replenishment of new trays within the management period set by the setting unit 345 with reference to the specific time. Thus, the tray feeder 2000, which can supply a new tray during the management period, can perform "collective replenishment" in which the replenishment work of the tray by the operator is collectively performed. Therefore, the operator can perform "collective replenishment" of the new pallet using the specific time as a reference for the management period as a standard of the work start time of the replenishment work. Therefore, the load of the replenishment work by the operator can be reduced.

The replenishment timing determination unit 348 determines a replenishment timing of a new tray in the same management period for the tray feeder 2000 determined by the replenishment target determination unit 347 as the component replenishment target device. This allows the operator to perform a new tray replenishment operation at the same replenishment timing with respect to tray feeder 2000 identified as the component replenishment target device.

< third modified embodiment >

Fig. 27 is a diagram showing a lever feeder 3000 as a component supply device according to a third modification. The lever feeder 3000 is provided in the component supply section 24 of the mounting machine 2. A plurality of rod feeders 3000 can be provided in parallel in the component supply section 24. The lever feeder 3000 is configured to supply the components E stored in a cylindrical rod 3009 as a component storage member while pushing out the components E from the rod 3009. The lever feeder 3000 includes a frame body 3001, a lever base 3002 provided on an upper portion of the frame body 3001, a first chuck 3003, a second chuck 3004, a component pushing mechanism 3005, a guide frame 3006, a pair of guide rails 3007, and a conveyor 3008.

The frame body 3001 has a hollow box shape with an open upper portion. The lever block 3002 is disposed inside the upper portion of the frame body 3001. The plurality of rods 3009 can be placed on the rod table 3002 in a stacked state. The first chuck 3003 can simultaneously hold the tip end portions of the rods 3009 other than the lowermost layer among the plurality of rods 3009 on the rod table 3002. Similarly, the second chuck 3004 can hold the rear end portions of the rods 3009 other than the lowermost layer among the plurality of rods 3009 on the rod table 3002 at the same time.

The element pushing mechanism 3005 pushes the element E forward from the lowermost lever 3009 of the plurality of levers 3009 on the lever base 3002. A guide frame 3006 is fixed to the front portion of the frame body 3001, and a pair of guide rails 3007 are supported by the guide frame 3006. Further, a conveyor 3008 is provided between the pair of guide rails 3007. The component E pushed forward by the component pushing mechanism 3005 is conveyed along the pair of guide rails 3007 by the conveyor 3008. Thereby, the component E received in the rod 3009 is supplied to the component supply position.

When the lowermost rod 3009 is disconnected with the component supply operation, the first and second chucks 3003, 3004 hold the rods 3009 other than the lowermost layer. In this state, the lever table 3002 is displaced to the support release position where the support of the lever 3009 is released, and thus only the lowermost lever 3009 falls by its own weight to the inner bottom of the frame body 3001. After discarding the component broken bar 3009, the bar table 3002 is returned to the supporting position of the bar 3009, and the first and second chucks 3003, 3004 are opened, whereby the remaining bar 3009 is placed on the bar table 3002, and the component E is supplied from the next (lowermost) bar 3009.

In the production of the mounted substrate, when the rod 3009 to be disconnected from the component falls to the inner bottom of the frame body 3001, the worker can supply a new rod to the rod feeder 3000.

In addition, in each of the plurality of lever feeders 3000, the number of the levers 3009 that store the components E of the same component type may be different for each lever feeder 3000. In such a case, the number of supplies for new bars filled with the same components is different in each bar feeder 3000. Further, the number of rods to be replenished may vary depending on the number of remaining components of the whole of the component type when a new rod is replenished.

Here, the management of the new bar replenishment to the bar feeder 3000 is performed by the first element replenishment management system 3 or the second element replenishment management system 3A. The replenishment management by the first component replenishment management system 3 will be described below.

In the first component replenishment management system 3, the replenishment target specifying unit 347 specifies, as the component replenishment target devices, all the bar feeders 3000 capable of performing replenishment of new bars within the management period set by the setting unit 345 with reference to the specific timing. Thus, the lever feeder 3000, which can supply new levers during the management period, can perform "collective supply" in which the supply work of the levers by the operator is collectively performed. Therefore, the operator can perform "collective replenishment" of the new pole using the specific time as a reference for the management period as a standard of the work start time of the replenishment work. Therefore, the load of the replenishment work by the operator can be reduced.

The replenishment timing determination unit 348 determines a replenishment timing of a new lever in the same management period for the lever feeder 3000 determined by the replenishment target determination unit 347 as the component replenishment target device. This allows the operator to perform a new rod replenishment operation at the same replenishment timing for the rod feeder 3000 identified as the component replenishment target device.

< fourth modified embodiment >

Fig. 28 is a diagram showing a lever feeder 4000 as a component supply device according to a fourth modification. The lever feeder 4000 is provided in the component supply section 24 of the mounter 2. A plurality of rod feeders 4000 may be provided in parallel in the component supply section 24.

The lever feeder 4000 has the same basic structure as the lever feeder 3000 described above. Rod feeder 4000 includes a first magazine 4009 that houses a plurality of rods 4011 containing components E in a stacked state and a second magazine 4010 that houses a plurality of rods 4012 containing components E in a stacked state. The element E received in the rod 4011 and the element E received in the rod 4012 are of the same kind. The first magazine 4009 and the second magazine 4010 function as a component housing member that houses a plurality of rods 4011 and 4012 housing components E. In the example shown in fig. 28, the rods 4012 accommodated in the second magazine 4010 are placed in a stacked state on a rod table 4002 disposed inside the upper portion of the frame body 4001, and the rods 4011 accommodated in the first magazine 4009 are arranged above the rod table in a stacked state.

In the lever feeder 4000, the component pushing mechanism 4005 pushes the component E forward from the lowermost lever 4012 among the plurality of levers 4012 stored in the second magazine 4010 arranged below on the lever table 4002. The component E pushed forward by the component pushing mechanism 4005 is conveyed by the conveyor 4008 along a pair of rails 4007 supported by the guide frame 4006. Thereby, the component E received in the rod 4012 is supplied to the component supply position.

When the lowermost rod 4012 becomes a component supply breakage in accordance with the component supply operation, the first and second chucks 4003, 4004 hold the rods 4012 other than the lowermost layer in the second magazine 4010 and all the rods 4011 in the first magazine 4009. In this state, the lever table 4002 is displaced to a support release position where the support of the levers 4011 and 4012 is released, and thus only the lever 4012 at the lowermost layer in the second magazine 4010 is dropped to the inner bottom of the frame main body 4001 by its own weight. Further, after discarding the rod 4012 in which the component is broken, the rod table 4002 is returned to the supporting position of the rods 4011, 4012, and the first and second chucks 4003, 4004 are opened, whereby the remaining rods 4011, 4012 are placed on the rod table 4002, and the component E is supplied from the next (lowermost) rod 4012 in the second magazine 4010.

In the production of the mounted substrate, when all the rods 4012 in the second magazine 4010 become the component supply-disconnection, the components E are supplied from the rods 4011 in the first magazine 4009. When all the rods 4012 in the second magazine 4010 become component supply-disconnected, the operator can supply a new magazine with the rod feeder 4000. Here, the management of replenishment of the new magazine of the rod feeder 4000 is performed by the first component replenishment management system 3 or the second component replenishment management system 3A. The replenishment management by the first component replenishment management system 3 will be described below.

In the first component replenishment management system 3, the replenishment target specifying unit 347 specifies, as the component replenishment target devices, all the bar feeders 4000 capable of performing replenishment of new magazines within the management period set by the setting unit 345 with reference to the specific timing. Thus, the lever feeder 4000, which can supply a new magazine during the management period, can perform "collective supply" in which the supply work of the magazines by the operator is collectively performed. Therefore, the operator can perform "collective replenishment" of the new magazine with the specific time as a reference of the management period as a criterion of the work start time of the replenishment work. Therefore, the load of the replenishment work by the operator can be reduced.

Further, replenishment timing determination unit 348 determines a replenishment timing of a new magazine in the same management period for lever feeder 4000 determined as the component replenishment target device by replenishment target determination unit 347. This allows the operator to perform a new magazine replenishment operation at the same replenishment timing for the lever feeder 4000 specified as the component replenishment target device.

< fifth modified embodiment >

In each component supply section 24 of the mounting machine 2, 2 or more types of component supply devices having different component supply systems may be arranged. For example, it is assumed that AF241 is provided in parallel in the first component supply section 24, a plurality of patch feeders are provided in parallel in the second component supply section 24, a plurality of tray feeders 1000 and 2000 are provided in parallel in the third component supply section 24, and a plurality of rod feeders 3000 and 4000 are provided in parallel in the fourth component supply section 24 among the 4 component supply sections 24 of the mounter 2.

The replenishment management of the new component storage members of the AF241, the tray feeders 1000 and 2000, and the lever feeders 3000 and 4000 is performed by the first component replenishment management system 3 or the second component replenishment management system 3A. The replenishment management by the first component replenishment management system 3 will be described below.

In the first component replenishment management system 3, the replenishment target specification unit 347 specifies, as the component replenishment target devices, all of the component supply devices capable of performing replenishment of new component storage members within the management period set by the setting unit 345 with reference to the specific timing. Thus, the AF241, the tray feeders 1000 and 2000, and the lever feeders 3000 and 4000, which can supply new component storage members during the management period, can perform "collective supply" in which the supply work of the component storage members by the operator is collectively performed. Therefore, the operator can perform "collective replenishment" of the new component storage members using the specific time as a reference for the management period as a criterion of the work start time of the replenishment work. Therefore, the load of the replenishment work by the operator can be reduced.

The replenishment timing determination unit 348 determines the replenishment timing of a new component storage member in the same management period for the component supply device determined by the replenishment target determination unit 347 as the component replenishment target device. Thus, the operator can perform a new component storage member replenishment operation at the same replenishment timing for AF241, tray feeders 1000 and 2000, and lever feeders 3000 and 4000 which are specified as the component replenishment target devices.

Further, when the specific time for specifying the specific time is set to a time at which the splicing work on the splice feeder is estimated to occur in the vicinity of the specific time, the worker can perform the splicing work on the splice feeder together with the replenishment work on AF241, tray feeders 1000 and 2000 and rod feeders 3000 and 4000 in the management period with the specific time as a reference.

The above embodiments mainly include the inventions having the following technical means.

A component replenishment management system according to an aspect of the present invention manages replenishment of component storage members to each of a plurality of component supply apparatuses provided in a mounting machine that mounts components on a board to produce a mounted board, the component supply apparatuses being capable of mounting a plurality of component storage members in which components are stored, the component replenishment management system comprising: an acquisition unit configured to acquire a management start time indicating a start time of management of replenishment of the component storage member for each of the plurality of component supply devices; a setting unit that sets a specific period from the management start time to a specific time after a predetermined specific time has elapsed; a component supply monitoring unit that monitors a supply state of components in each of the plurality of component supply devices, and determines a resupply possible time, which is a time at which a preceding component accommodating member, which has first been subjected to component supply, of the plurality of component accommodating members becomes a component supply-disconnection state and a new component accommodating member can be replenished, for each of the plurality of component supply devices; and a replenishment target specifying unit that specifies the component supply device whose replenishment possible timing is a timing earlier than the specific timing as a component replenishment target device to be replenished by the new component housing member in the specific period.

According to this component replenishment management system, the replenishment target specifying unit specifies the component supply device to be replenished with the new component storage member in the specific period set by the setting unit among the component supply devices. Here, the specific period set by the setting unit is a period from the management start time acquired by the acquisition unit to a specific time after a predetermined specific time has elapsed, and is a period based on the specific time. The replenishment target specifying unit specifies, as a component replenishment target device to be replenished with a new component housing member during the specific period, a component supplying device whose replenishment possible timing is a timing earlier than the specific timing.

In this way, the component replenishment management system specifies, as a component replenishment target device, a component supply device capable of replenishing new component storage members in a specific period with reference to a specific time. Thus, the operator can collectively perform "collective replenishment" which is a task of replenishing the component storage members in the component supply device capable of replenishing the component storage members in a predetermined period. Therefore, the operator can perform "collective replenishment" of the component storage members with the specific time as a reference of the specific period as the work start time of the replenishment work. Therefore, the frequency of the operator going to the mounting machine with the component supply device can be reduced, and the load of the replenishment work performed by the operator can be reduced.

The component replenishment management system described above may further include: and a replenishment timing determination unit configured to determine a replenishment timing of a new component housing member in the same specific period for all the component replenishment target devices determined by the replenishment target determination unit.

In this configuration, the replenishment timings for the component storage means of all the component replenishment target devices specified by the replenishment target specification unit are the same replenishment timing during the specified period. This allows the operator to perform the component storage member replenishment work for the component replenishment target device at the same replenishment timing.

In the component replenishment management system described above, the replenishment timing determination unit may determine a target replenishment possible time that is the latest time among the replenishment possible times corresponding to the component replenishment target devices, and determine an arbitrary time between the target replenishment possible time and the specific time as the replenishment timing.

The time period between the noticed resupply time and the specific time is a time period in which the component storage means can be replenished to all the component replenishment target devices whose resupply time is earlier than the specific time. That is, the time period between the noticed resupply time and the specific time is a time period during which the operator can collectively perform the "collective replenishment" of the component storage members to the component replenishment target apparatus. The replenishment timing determination unit determines an arbitrary timing between the target replenishment possible timing and the specific timing as a replenishment timing for replenishing the component storage means to the component replenishment target device. This enables the operator to perform the operation of replenishing the component storage means to the component replenishment target device at an arbitrary replenishment timing between the notable replenishing-possible timing and the specific timing.

In the component replenishment management system described above, the setting unit may be configured to set a predetermined management period having a latest time as the specific time within the specific period, and the replenishment timing specifying unit may identify a target device whose replenishment possible time is later than the earliest time of the management period among the component replenishment target devices, specify the latest time among the replenishment possible times corresponding to the target device as the target replenishment possible time, and specify the target replenishment possible time within the management period as the replenishment timing.

As described above, the time period between the noticed resupply time and the specific time is a time period during which the operator can collectively perform the "collective replenishment" of the component storage members in the component replenishment target apparatus. The eye-on resupply time is the earliest time in the period in which "intensive replenishment" is possible. By specifying such a notice replenishment timing as a replenishment timing for replenishing the component storage means to the component replenishment target device, the operator can perform "concentrated replenishment" with time being sufficient.

In the component replenishment management system described above, the replenishment timing determination unit may determine the specific time as the replenishment timing.

In this configuration, the operator can perform the operation of replenishing the component storage member to the component replenishment target device with the specific timing as the replenishment timing.

The component replenishment management system described above may further include: a recommendation start time specifying unit that specifies a next recommendation start time recommended as a start time of a next replenishment management in a period of time after the specific time; wherein the recommended start time determining unit determines, as the next recommended start time, the earliest time among the resupply possible times corresponding to the remaining component supply apparatuses, from among the plurality of component supply apparatuses, other than the component replenishment target apparatus.

In this configuration, the operator can grasp the next recommended start time, which is the start time of the next replenishment management, after the specific time. After grasping the next recommended start time, the operator can predict the timing of the next replenishment job by adding a predetermined specific time to the next recommended start time. This makes it easy for the operator to plan the replenishment work.

In the above-described component replenishment management system, the setting unit may divide a period to be subjected to replenishment management of the component storage means after the management start time into a plurality of specific periods at intervals of the specific time, and the replenishment target specifying unit may specify the component replenishment target device for each of the plurality of specific periods.

In this configuration, the replenishment target specifying unit specifies the component replenishment target device to be replenished by the new component storage means for each of a plurality of specific periods divided at specific time intervals. Thus, the operator can collectively perform "collective replenishment" of the component storage members by the component supply device capable of replenishing the component storage members for each of the plurality of specific periods.

In the component replenishment management system described above, the setting unit may set the time interval to be constant for each of the plurality of specific periods.

In this configuration, the operator can periodically perform the component storage member replenishing operation on the component replenishing object apparatus at regular time intervals.

The component replenishment management system described above may further include: an operation unit that receives an input operation of instruction information related to setting of the time interval in the specific period; wherein the setting unit sets the time interval in each of the plurality of specific periods based on the instruction information.

In this configuration, the operator can specify the time interval in each of the plurality of specific periods through the operation unit. This makes it easy for the operator to plan the component storage member replenishment work for the component replenishment target device.

The component replenishment management system described above may further include: an adjustment unit that calculates the number of the component supply target devices specified by the supply target specification unit for each of the plurality of specific periods, and adjusts the number of the component supply target devices for each of the plurality of specific periods based on a result of the calculation; wherein, regarding the number of the component replenishment target devices in each of the specific periods adjacent in time series, when the number of first specific periods of interest earlier in time series is larger than a predetermined reference number and the number of second specific periods of interest later in time series is smaller than the reference number, the adjusting section performs the replenishment number adjustment processing of the component replenishment target device that allocates a part of the component replenishment target devices in the first specific periods of interest as replenishment targets of new component housing means in the second specific periods of interest.

In this configuration, the adjusting unit performs the replenishment quantity adjusting process of adjusting the quantity of the device replenishment target apparatuses for each of the plurality of specific periods. The adjusting unit performs the replenishment quantity adjusting process when the number of the device replenishment target apparatuses in each of the specific periods adjacent in time series is greater than a predetermined reference number in a first specific period of interest earlier in time series and is less than the reference number in a second specific period of interest later in time series. In the replenishment quantity adjustment processing, the adjustment unit allocates a part of the device to be replenished in the first specific attention period as the device to be replenished in the second specific attention period. This makes it possible to equalize the load of the component accommodating member replenishment work performed on the component replenishment target device for each of a plurality of specific periods.

In the component replenishment management system described above, the component supply monitoring unit may determine, for each of the plurality of component supply devices, a remaining number warning timing at which a total remaining number of components stored in the plurality of component storage means reaches a predetermined remaining number warning value, and the adjusting unit may not perform the replenishment amount adjustment process when the remaining number warning timing is included in a third notable specific period adjacent to the second notable specific period in chronological order.

In the replenishing operation to the component replenishing apparatus in the second specific attention period, the replenishing operation to the component replenishing apparatus including the remaining number of warning timings in the third specific attention period adjacent to the second specific attention period on the later side in the time series becomes a highly urgent operation, and a careful operation is required. In this way, when the remaining number warning time is included in the third attention specific period and it is expected that the replenishment work in the second attention specific period will become a highly urgent work, the adjustment unit does not perform the replenishment number adjustment process. Thus, a part of the device to be replenished in the first predetermined period of attention is not distributed to the second predetermined period of attention. Therefore, the operator can perform the highly urgent replenishing operation with emphasis on the second attention specifying period.

Another aspect of the present invention relates to a component mounting system including: a mounting machine which is provided with a plurality of component supply devices capable of mounting a plurality of component housing members housing components and mounts the components on a substrate to produce a mounted substrate; and the component replenishment management system described above that manages replenishment of the component storage members to each of the plurality of component supply devices.

According to this component mounting system, since the component replenishment management system capable of reducing the load of the replenishment work performed by the operator is provided, the component supply stop of the component supply device due to the delay of the replenishment work performed by the operator can be avoided as much as possible in the production of the mounted boards. Therefore, the reduction of the production efficiency of the mounted substrate can be prevented.

As described above, according to the present invention, it is possible to provide a component replenishment management system capable of reducing a load of a component storage member replenishment operation performed by an operator to a component supply device, and a component mounting system including the component replenishment management system.
