Disclosure of Invention

Problems to be solved by the invention

However, the printing apparatus is not assumed to include both the recovery plate and the supply device. Since the recovery plate and the supply device function in a common work area, there is a problem that components interfere with each other.

The present disclosure has been made in view of the above problems, and a main object thereof is to provide a supply unit, a printing apparatus, and a method of controlling a printing apparatus, which can prevent interference between components.

Means for solving the problems

In order to achieve the above-described main object, the supply unit, the printing apparatus, and the method for controlling the printing apparatus disclosed in the present specification adopt the following means.

That is, the supply unit of the present disclosure is used for a printing apparatus that supplies a viscous fluid, and the printing apparatus includes: a print head that performs printing processing of the viscous fluid on a printing object using a screen mask; and a recovery unit having a recovery member that comes into contact with the screen mask to recover and move the viscous fluid, and a recovery moving unit that moves the recovery member in a predetermined printing direction, wherein the supply unit includes: a supply unit having a fitting unit capable of fitting and releasing a cartridge containing the viscous fluid; a driving unit that moves the supply unit in a supply operation direction; a detection section; and a supply section detection section that detects whether or not the supply section is located in a passage space where the collection section does not contact the supply section, based on a position of the detection member.

In the supply unit, whether the supply portion is located in the passage space where the collection portion does not contact the supply portion is detected based on the position of the detection member. Therefore, in the supply unit, the supply unit can be operated in the passage space where no physical disturbance occurs when the collection unit is operated. Therefore, the components of the collection unit and the supply unit can be prevented from interfering with each other. Here, examples of the "printing target" include a substrate on which a device is mounted, a three-dimensional object, and the like. The "viscous fluid" includes solder paste, conductive paste, adhesive, and the like.

Fig. 7 is an explanatory diagram of the printing section 24, the supply unit 40, and the recovery section 60 as viewed from the side. Fig. 8 is a block diagram showing an electrical connection relationship of the printing apparatus 11. The mounting system 10 is a system for mounting a component on the substrate S, for example. The mounting system 10 includes a printing apparatus 11, a mounting apparatus 12, and a management computer (PC) 90. The mounting system 10 is configured as a mounting line in which a plurality of mounting devices 12 for mounting components on the substrate S are arranged downstream of the printing device 11. In the present embodiment, the left-right direction (X axis), the front-rear direction (Y axis), and the up-down direction (Z axis) are as shown in fig. 1 to 7 and 11.

The mounting device 12 is a device for mounting components on the substrate S on which the viscous fluid such as solder paste is printed by the printing device 11. The management PC90 is a device that manages information of each device of the installation system 10. The management PC90 manages the progress status of each device in the installation line. Each device in the installation system 10 exchanges information with the management PC90, and acquires information such as the progress status of other devices.

The printing apparatus 11 is an apparatus that applies (prints) solder paste as a viscous fluid to a substrate S as a printing object below via a pattern hole formed in a screen mask M by pressing the solder paste on the screen mask M into the pattern hole using a squeegee 27. Examples of the "printing target" include a substrate S on which components are mounted, a three-dimensional object, and the like. The "viscous fluid" includes solder paste, conductive paste, adhesive, and the like. Here, the substrate S and the solder paste will be described as an example. The printing apparatus 11 includes a main body 14, a control unit 20 (see fig. 8), a printing unit 24, a mask unit 28, a substrate processing unit 30, a cleaning unit 32, an imaging unit 35, a supply unit 40 as a supply unit, and a recovery unit 60. The control unit 20 is a microprocessor including a CPU21 as a center, and controls the entire printing apparatus 11.

The printing unit 24 is a unit disposed at an upper stage of the printing apparatus 11, and prints a viscous fluid on the substrate S using the screen mask M. The printing unit 24 includes a print head 25, a print moving unit 26, a squeegee elevating unit, and a squeegee 27. The printing moving unit 26 moves the printing head 25 in a predetermined printing direction (in this case, the front-rear direction), and includes a slider that moves along a guide formed in the front-rear direction, and a motor that drives the slider. The printing moving unit 26 has a linear encoder, not shown, and can grasp the position of the print head 25. The squeegee 27 is disposed on the lower surface side of the print head 25 and is moved up and down by a squeegee raising and lowering unit. The printing portion 24 has two blades 27 used in the front-rear direction, respectively. The printing unit 24 can be connected to and disconnected from the supply unit 40, and the printing moving unit 26 moves the supply unit 40 together with the print head 25. The supply unit 40 does not include a moving unit such as a motor, but is coupled to the printing unit 24 by a coupling unit 46 and moved in the front-rear direction between the supply area and the standby area by the printing moving unit 26 (see fig. 7). The engaging member 23 is a member connected to the supply unit 40 via a connection portion 46 provided in the supply unit 40 (see fig. 7). The engaging member 23 is provided with an insertion hole into which the fixing rod of the connecting portion 46 is inserted.

The mask portion 28 is disposed between the printing portion 24 and the substrate processing portion 30 in the vertical direction, and is a unit that fixedly holds the screen mask M. The mask portion 28 includes a mask fixing portion 29. The mask fixing unit 29 positions and supports the screen mask M in a horizontal posture. The substrate processing unit 30 is a unit including: the substrate S is carried in below the mask unit 28, and the carried-in substrate S is positioned and supported so as to be in contact with and separated from the screen mask M. The substrate processing unit 30 includes: a substrate conveying unit 31 for conveying the substrate S in the left-right direction; a substrate support member that supports the substrate S from below; and a support lifting unit for lifting and lowering the substrate support member and the entire substrate processing unit 30. The printing apparatus 11 includes a substrate processing unit 30 that transports the fixed substrate S in two passes. The cleaning unit 32 is a unit that is disposed between the mask unit 28 and the substrate processing unit 30 in the vertical direction and performs a cleaning process of cleaning the rear surface of the screen mask M by the cleaning member 33. The cleaning member 33 is exemplified by cleaning paper. The imaging unit 35 includes a camera 36 that images the substrate S and the screen mask M. The control unit 20 performs alignment of the screen mask M and the substrate S based on the captured image.

The supply unit 40 is a unit that is disposed above the mask portion 28 so as to be movable to the same height as the printing portion 24, and supplies the solder paste contained in the cartridge 51 onto the screen mask M. In the cartridge 51, a storage container 52 containing solder paste is disposed inside thereof, and pressurized air is supplied thereto to eject the solder paste to the outside. The supply unit 40 is disposed in front of the print head 25 (see fig. 7). As shown in fig. 2, the supply unit 40 includes a mounting portion 41, a limiting wall portion 42, a driving portion 43, a cover member 44, a fixing mechanism 45, a supply portion detection portion 48, and a detection member 47 (see fig. 4). The mounting portion 41, the regulating wall portion 42, and the cartridge 51 constitute a supply portion 50 that is moved by the driving portion 43. The supply unit 50 is disposed below a unit case 49 formed in the left-right direction of the apparatus, and is moved in the supply operation direction (left-right direction) by a drive unit 43 disposed in the unit case 49. The fitting portion 41 is used to fit the cartridge 51 or to release the fitting of the cartridge 51. A snap lock having a hook and a rotating lever is disposed on the cartridge 51, and the cartridge 51 is assembled and fixed to the assembly portion 41 by the snap lock. The restricting wall 42 is a wall member that covers the cartridge 51 and restricts contact with the inside of the printing apparatus 11. The restricting wall portion 42 is a member that prevents a part of the body of the operator, some members, and the like from entering the inside of the device having a structure that operates when the door member 16 is opened. The driving portion 43 moves the cartridge 51 mounted to the mounting portion 41 in the feeding operation direction together with the regulating wall portion 42. The driving unit 43 includes a driving roller to which a motor is connected, a driven roller, and a belt stretched in the left-right direction between the driving roller and the driven roller. The attachment portion 41 and the regulating wall portion 42 are fixed to the belt, and the attachment portion 41 and the regulating wall portion 42 are moved in the feeding operation direction by driving the belt. The cover member 44 covers the front and upper sides of the unit case 49, and protects the driving unit 43 and the like. The fixing mechanism 45 is a mechanism for fixing the supply unit 50 at the standby position, and is composed of a fixing stay and a hook member engaged with the tip of the fixing stay (see fig. 3). The connection portion 46 connects and disconnects the supply unit 40 and the printing portion 24 (printing moving portion 26), and includes a fixing rod and an air cylinder that moves the fixing rod up and down (see fig. 7).

As shown in fig. 4, the detecting member 47 is a plate-like member whose longitudinal direction is the feeding operation direction. The detecting member 47 is disposed at the upper center of the supply unit 50 that moves in the supply operation direction, and moves in the supply operation direction together with the supply unit 50. The detection means 47 is a means for detecting whether or not the supply unit 50 is present in a predetermined non-interference region (passage space) in the supply operation direction by the supply unit detection unit 48. The detection member is formed to have a length L (see fig. 11) in the supply operation direction in which the supply unit 50 moves within a range in which the supply unit 50 does not contact the collection unit 60 (see fig. 5 to 8). The supply portion detection portion 48 is a non-contact sensor in which a detection space through which the detection member 47 passes is formed. The supply section detector 48 is disposed in a unit case 49 as a fixed member that does not move in the supply operation direction. The supply section detector 48 outputs a signal when the detector 47 is present in the detection space. The supply section detection section 48 includes two sensors, i.e., a detection sensor 48a and a detection sensor 48 b. The supply unit detection unit 48 is a sensor that detects whether or not the supply unit 50 is located in a passage space where the collection unit 60 does not contact the supply unit 50, based on the position of the detection member 47, and will be described in detail later.

The supply section detector 48 is disposed at a predetermined position of the unit case 49 corresponding to the center of the collection member 61 or the center of the passage space. For example, when the detection member 47 is positioned on the right side in fig. 4 and the left end portion of the detection member 47 is separated from the detection sensor 48a, the supply portion detection unit 48 outputs a signal only from the detection sensor 48 b. Similarly, the supply section detector 48 outputs a signal only from the detection sensor 48a when the detection member 47 is positioned on the left side in fig. 4 and the right end portion of the detection member 47 is separated from the detection sensor 48 b. When the detection member 47 is separated from the supply section detection section 48, no signal is output, and when the detection member 47 is present in the detection space of the detection sensors 48a and 48b, signals are output from both sensors. In this way, the supply section detection section 48 can grasp the approximate position and state of the supply section 50 based on the output signals from the two detection sensors 48a and 48 b.

The recovery portion 60 is a unit that recovers the solder roller remaining on the screen mask M to the recovery member 61 by the squeegee 27. The printing apparatus 11 includes two recovery units 60a and 60b, and corresponds to one-way printing and two-way printing. Here, the recovery units 60a and 60b are collectively referred to as the recovery unit 60. The recovery unit 60 includes a recovery member 61 and a recovery moving unit 62. The recovery member 61 is a member that comes into contact with the screen mask M, mounts the solder roller thereon, and recovers and moves the solder roller. The recovery member 61 is a thin plate-like member having a longitudinal direction in the feeding operation direction, and tapered surfaces are formed on both sides in the printing direction to facilitate transfer of the solder roll to and from the screen mask M (see fig. 5). The recovery moving unit 62 supports the recovery member 61 and moves it in a predetermined printing direction (front-back direction). The collection moving unit 62 includes a support member 63, an elevating unit 64, and a driving unit 65. The support member 63 is a member that moves along a guide 66 formed in the printing direction, and supports the lifting unit 64. The elevating portion 64 is a columnar member having a cylinder formed therein. The elevating portion 64 has an upper end fixed to the support member 63 and a lower end side into which a support rod to which the recovery member 61 is fixed is inserted. Pressurized air, not shown, is supplied to the elevating section 64, and the support rod is moved up and down to move the recovery member 61 up and down. The driving unit 65 includes a driving roller to which a motor is connected, a driven roller, and a belt stretched over the driving roller and the driven roller in the front-rear direction. A support member 63 is fixed to the belt, and the support member 63 is moved in the printing direction by driving the belt. A linear encoder, not shown, is formed along the guide 66 in the recovery unit 60, so that the position of the recovery member 61 in the printing direction can be grasped. Although not shown, the recovery unit 60 is provided with an origin sensor for detecting the origin of the recovery unit 60, a contact prevention sensor for preventing the recovery units 60a and 60b from coming into contact with each other, an end sensor for detecting that the recovery unit 60 has reached the end of the movement range, and the like.

Here, the positional relationship among the printing unit 24, the supply unit 40, and the recovery unit 60 will be described. As shown in fig. 6, the blade 27 of the printing portion 24 is formed to be shorter than the lateral width of the collecting member 61, and when it is located at the raised position, it does not interfere with (come into contact with) the collecting portion 60 even if it moves beyond the collecting member 61. On the other hand, as shown in fig. 6 (a), when the supply unit 50 moves backward in a state where the cartridge 51 can be replaced, it comes into contact with the support member 63, the elevating unit 64, the support rod, and the like of the collection moving unit 62. On the other hand, as shown in fig. 6 (B), when the supply portion 50 is located in the passage space formed between the collection moving portions 62, the supply portion does not contact the collection portion 60 regardless of the height of the collection member 61. Since the supply unit 40 and the recovery unit 60 perform operations above the screen mask M, for example, in an interference area where the supply unit 50 and the recovery unit 60 may interfere with each other and a supply area where the solder paste is supplied from the supply unit 50 as shown in fig. 7, there is a problem that they contact each other if they are operated without limitation. In the printing apparatus 11, the supply unit 50 is controlled using the detection member 47 and the supply unit detection unit 48 so that the supply unit 50 does not contact the collection unit 60, which will be described in detail later.

Next, the operation of the printing apparatus 11 configured as above, and the operation of the first printing process will be described. Fig. 9 is a flowchart showing an example of a print processing routine executed by the CPU21 of the control unit 20. This routine is stored in the storage unit of the control unit 20 and executed as the operator inputs the start of the printing process. When executing this routine, the CPU21 causes the substrate processing section 30 to convey the fixed substrate S (S100), causes the imaging section 35 to read the reference marks of the substrate S and the screen mask M, aligns the substrate S and the screen mask M (S110), and causes the printing section 24 to execute the printing process (S120). In the printing process, the print head 25 is moved, and a viscous fluid (here, solder paste) is supplied onto the substrate S disposed on the lower surface of the screen mask M by the squeegee 27. At this time, when the viscous fluid (solder roller) on the screen mask M after the previous printing process is not at the current printing start position, the CPU21 places the viscous fluid on the recovery member 61 of the recovery unit 60 and moves the viscous fluid to the printing start position by the recovery moving unit 62, and then performs printing by the squeegee 27. The substrate S after the printing process is transported to the next apparatus by the substrate processing unit 30. Next, the CPU21 determines whether or not the timing is to supply the viscous fluid (S130). This determination can be made, for example, based on whether or not a predetermined supply time has elapsed after the printing process time. The determination can also be made by detecting the size (amount) of the viscous fluid on the screen mask M. When the timing for supplying the viscous fluid is S130, the CPU21 executes the process of supplying the viscous fluid (S140). After S140 or when the supply timing of the viscous fluid is not at S130, the CPU21 determines whether or not the cleaning timing of the screen mask M is the timing (S150). This determination can be made, for example, based on whether or not a predetermined cleaning time has elapsed after the printing process time. When it is the timing for cleaning the screen mask M, the cleaning process of the screen mask M by the cleaning portion 32 is executed (S160). After S160 or when the timing for cleaning the screen mask M is not reached in S150, the CPU21 determines whether or not the production process of the substrate S is completed (S170), and if the production process of the substrate S is not completed, the processes from S100 onward are executed. On the other hand, when the production process of the substrate S is completed in S170, the routine is ended.

Next, the operation of the supply processing performed by the supply unit 40 in S140 will be described. Fig. 10 is a flowchart showing an example of a viscous fluid supply processing routine executed by the CPU21 of the control unit 20. This routine is stored in the storage unit of the control unit 20, and executed in S140 of the print processing routine. When executing this routine, the CPU21 couples the printing unit 24 to the supply unit 40 (S200), and determines whether or not the supply unit detection unit 48 has detected the detection member 47 based on the signal input from the supply unit detection unit 48 (S210). When the detection member 47 is not detected, the CPU21 moves the supply unit 50 in the supply operation direction by the drive unit 43 so that the supply unit detection unit 48 detects the detection member 47 (S220). When the supply unit 50 is located at the standby position, which is the initial position, the CPU21 moves the supply unit 50 toward the center where the supply unit detection unit 48 is disposed, based on the value of the linear encoder of the drive unit 43. Next, the CPU21 determines whether or not the supply unit 40 is in an interference region (see fig. 7) where interference with the collection unit 60 occurs, based on the value of the linear encoder of the print moving unit 26 (S230). When the supply unit 40 is not in the interference area, the CPU21 moves the supply unit 40 toward the supply area in the printing direction by the printing movement unit 26 (S240) and executes the processing after S210 because the supply unit 50 and the recovery unit 60 do not interfere with each other. That is, the CPU21 tilts the supply unit 50 so that the supply unit 50 does not contact the recovery unit 60 before the supply unit 40 reaches the interference region, thereby shortening the movement time of the supply unit 50.

On the other hand, when the supply section detector 48 detects the detection member 47 in S210, the CPU21 moves the supply unit 40 to the supply position where the viscous fluid (solder roll) is located (S250). When the solder roll is positioned on the screen mask M, the screen mask M becomes the supply position, and when the solder roll is positioned on the recovery member 61, the recovery member 61 becomes the supply position. Next, when the supply unit 40 reaches the supply position, the CPU21 moves the supply unit 50 in the supply operation direction (S260), and pressurizes the cartridge 51 to supply the viscous fluid to the viscous fluid (S270). Next, the CPU21 determines whether the output signal from any one of the detection sensors of the supply section detection section 48 is no longer input, that is, whether the end of the detection member 47 has deviated from one of the detection sensors (S280). When the output signal from any one of the detection sensors is no longer input, the CPU21 determines that the end of the detection member 47 has deviated from one of the detection sensors, that is, the supply unit 50 has reached the end side of the passage space, stops the continued movement of the supply unit 50, and changes the supply operation direction to move the supply unit 50 (S290). Fig. 11 is an explanatory diagram of the supply process by the supply unit 50, where fig. 11 (a) shows a state in which the supply unit 50 is moved to the left side and only the output signal of the detection sensor 48a is obtained, and fig. 11 (B) shows a state in which the supply unit 50 is moved to the right side and only the output signal of the detection sensor 48B is obtained. As shown in fig. 11, the CPU21 can reciprocate the supply unit 50 in the passage space that does not interfere with the collection unit 60 based on the output signal from the supply unit detection unit 48. Further, in the printing apparatus 11, even if the supply unit 50 moves beyond the state shown in fig. 11 (a) and 11 (B) and the output signals from the two detection sensors cannot be obtained, a predetermined margin is provided so that the supply unit 50 does not contact the collection unit 60.

After S290, or when the output signals from the two detection sensors are still obtained in S280, the CPU21 determines whether the supply of the viscous fluid is completed (S300). This determination can be made by whether or not the viscous fluid is supplied within a predetermined time. Alternatively, the determination may be performed by measuring the amount of the viscous fluid on the screen mask M. When the supply of the viscous fluid is not completed, the CPU21 executes the processing after S260. That is, the CPU21 executes the process of discharging the viscous fluid while reciprocating the supply unit 50 in the passage space, based on the output signal of the supply unit detection unit 48, until the supply of the viscous fluid is completed. On the other hand, when the supply of the viscous fluid is completed in S300, the CPU21 moves the supply unit 50 of the supply unit 40 to the standby position by the print moving unit 26 and the driving unit 43, releases the connection of the connection unit 46 (S310), and ends the routine. In S310, the CPU21 restricts the movement of the supply unit 50 in the supply operation direction within the disturbance region in order to obtain an output signal from at least one detection sensor of the supply unit detection unit 48, and when the supply unit 40 reaches the outside of the disturbance region, the restriction is terminated and the supply unit 50 is tilted to the standby position.

Here, the correspondence relationship between the components of the present embodiment and the components of the present disclosure is clarified. The cartridge 51 of the present embodiment corresponds to a cartridge, the mounting portion 41 corresponds to a mounting portion, the supply portion 50 corresponds to a supply portion, the drive portion 43 corresponds to a drive portion, the detection member 47 corresponds to a detection member, and the supply portion detection portion 48 corresponds to a supply portion detection portion. The screen mask M corresponds to a screen mask, the substrate S corresponds to a printing target, the solder paste corresponds to a viscous fluid, the collecting member 61 corresponds to a collecting member, the collecting moving unit 62 corresponds to a collecting moving unit, and the collecting unit 60 corresponds to a collecting unit. The unit case 49 corresponds to a fixing member, the control unit 20 corresponds to a control unit, the print head 25 corresponds to a print head, and the printing unit 24 corresponds to a printing unit. In the present embodiment, the supply unit of the present disclosure and the control method of the printing apparatus of the present disclosure are disclosed by the description of the printing apparatus 11.

The supply unit 40 of the present embodiment described above includes: a supply unit 50 having a mounting unit 41, the mounting unit 41 being capable of mounting a cartridge 51 containing solder paste as a viscous fluid and releasing mounting of the cartridge 51; a driving unit 43 for moving the supply unit 50 in the supply operation direction; a detection section 47; and a supply section detection section 48 that detects whether or not the supply section 50 is located in a passage space where the collection section 60 does not contact the supply section 50, based on the position of the detection member 47. In the supply unit 40, since the supply unit 50 can be operated in the passage space where physical interference does not occur when the collection unit 60 is operated, interference between the components of the collection unit 60 and the supply unit 50 can be prevented. The detection member 47 is formed to have a length L in the supply operation direction in which the supply unit 50 moves within a range in which the supply unit 50 does not contact the collection unit 60. In the supply unit 40, since the supply unit 50 is driven in a range in which the detection signal from the supply unit detection unit 48 is output, interference with the collection unit 60 can be prevented, and therefore, interference between the members can be easily prevented by the shape of the detection member 47. Further, the detection member 47 is disposed in the supply portion 50 that moves in the supply operation direction, and the supply portion detection portion 48 is disposed in the unit case 49 that is a fixed member that does not move in the supply operation direction. In terms of wiring, it is preferable that the supply unit detection unit 48 be disposed in the unit case 49 in accordance with the relationship between the supply unit detection unit 48 and an output line for outputting a signal, a power supply line, and the like.

In the interference region where the recovery unit 60 physically interferes with the supply unit 50, the control unit 20 controls the driving unit 43 to move the supply unit 50 in the supply operation direction in the passage space so that the supply unit detection unit 48 detects the detection member 47. In the supply unit 40, the components can be prevented from interfering with each other by the control of the control unit 20. Further, the supply unit detection unit 48 is configured by a plurality of detection sensors, and the control unit 20 controls the drive unit 43 so that the supply unit 50 moves in the supply operation direction in the passage space in a state where all the detection sensors detect the detection member 47, and controls the drive unit 43 so that the supply unit 50 stops continuing movement when any one of the detection sensors in the supply unit detection unit 48 does not detect the detection member 47. In the supply unit 40, by using the supply section detection unit 48 having a plurality of detection sensors, more reliable control and more detailed control can be performed. When the detection member 47 is not detected by any of the detection sensors of the supply section detection sections 48, the driving section 43 is controlled to change the moving direction of the supply section 50 based on the position of the supply section detection section 48 where the detection member 47 is not detected. In the supply unit 40, the movement control of the supply unit 50 including the movement direction of the supply unit 50 can be performed by using the plurality of detection sensors 48a and 48 b. For example, although it is conceivable to control the movement of the supply unit 50 using a linear encoder of the drive unit 43, it is preferable to directly detect the supply unit 50 using the supply unit detection unit 48 because more reliable control can be performed.

In addition, the control unit 20 controls the driving unit 43 so that the supply unit 50 moves in the direction in which the supply unit detection unit 48 detects the detection member 47, in a state in which the supply unit detection unit 48 does not detect the detection member 47. In the supply unit 40, interference between the components can be more reliably prevented. Further, the control unit 20 moves the supply unit 50 in the direction in which the supply unit detection unit 48 detects the detection member 47, by using the position information of the supply unit 50 of the linear encoder. In the supply unit 40, the supply unit 50 can be moved in a more reliable direction by using the positional information of the supply unit 50. The printing moving unit 26 moves the printing head 25 having the squeegee 27 for performing the printing process and the supply unit 40. In the printing apparatus 11, the moving section of the supply unit 40 also serves as the moving section of the print head 25, and therefore the structure can be further simplified.

The supply unit, the printing apparatus, and the method for controlling the printing apparatus of the present disclosure are not limited to the above embodiments, and may be implemented in various forms as long as they fall within the technical scope of the present disclosure.

For example, in the above embodiment, the detection member 47 is formed to have the length L in the supply operation direction in which the supply unit 50 moves in the range in which the supply unit 50 does not contact the collection unit 60, but is not particularly limited thereto. The detection member 47 may have any shape as long as it can detect whether or not the supply unit 50 is located in a passage space where the collection unit 60 does not contact the supply unit 50. In the above embodiment, one detection member 47 is used, but two or more detection members may be used as long as it can detect whether or not the supply unit 50 is located in the passage space where the collection unit 60 does not contact the supply unit 50.

In the above embodiment, the detection member 47 is disposed in the supply portion 50 that moves in the supply operation direction, and the supply portion detection portion 48 is disposed in the unit case 49 that does not move in the supply operation direction, but the present invention is not particularly limited as long as it can detect whether or not the supply portion 50 is located in the passage space where the collection portion 60 does not contact the supply portion 50. For example, the supply section detector 48 may be disposed in the supply section 50 that moves in the supply operation direction, and the detector 47 may be disposed in the unit case 49 that does not move in the supply operation direction. For the sake of wiring, the supply section detector 48 is preferably disposed on a fixed member that does not move in the supply operation direction.

In the above embodiment, the supply section detection unit 48 has two detection sensors 48a and 48b, but is not particularly limited thereto, and may have three or more detection sensors. The supply section detection section 48 may have one detection sensor. When the supply unit detection unit 48 includes one detection sensor, it is possible to detect whether or not the supply unit 50 is in the passage space, although it is not possible to obtain a margin for detection or detection in the moving direction of the supply unit 50. In the above embodiment, the detection member 47 is disposed at the center of the supply unit 50, and the supply unit detection unit 48 is disposed above the center of the collection member 61 (passage space), but may be disposed at a position other than the center of each part as long as it can detect that the supply unit 50 is located in the passage space.

In the above embodiment, the control unit 20 stops the continuous movement of the supply unit 50 and changes the movement direction when one of the output signals disappears after the output signals from both the detection sensors 48a and 48b are acquired, but the present invention is not particularly limited to this, and the control unit may stop the continuous movement of the supply unit 50 and change the movement direction when one of the output signals from both the detection sensors 48a and 48b disappears after the output signal from one of the detection sensors 48a and 48b disappears. In the supply unit 40, the detection member 47 and the supply section detection section 48 can be used to prevent the interference between the collection section 60 and the supply section 50.

In the above embodiment, the control unit 20 causes the supply unit 50 to be inclined before the supply unit 40 reaches the interference area, but the present invention is not particularly limited to this, and for example, the supply unit 50 may be moved in the supply operation direction, and the print moving unit 26 may move in the printing direction after the supply unit detection unit 48 detects the detection member 47. In the supply unit 40, although it takes a long time to move, the interference between the supply unit 50 and the recovery unit 60 can be more reliably prevented.

In the above embodiment, the printing moving section 26 moves the printing section 24 and the supply unit 40, but the present invention is not particularly limited thereto, and the supply unit 40 may be moved by a moving section different from the printing moving section 26. In this printing apparatus, although the number of moving units increases, interference between the recovery unit 60 and the supply unit 50 can be prevented. In the above embodiment, the driving portion 43 moves the supply portion 50 including the regulating wall portion 42 in the supply operation direction, but is not particularly limited thereto, and the movement of the regulating wall portion 42 may be omitted, or the regulating wall portion 42 itself may be omitted. In the supply unit 40, when the supply portion 50 does not have the restriction wall portion 42, the movement distance in the supply operation direction of the cartridge 51 can be further secured.

In the above embodiment, the recovery unit 60 includes the two recovery members 61 of the recovery units 60a and 60b, but is not particularly limited thereto, and only one recovery member 61 may be provided. With at least one recovery member 61, recovery of the viscous fluid, unidirectional printing, and the like at the time of replacement of the screen mask M can be performed.

Although the present disclosure has been described as the printing apparatus 11 including the supply unit 40 in the above embodiment, the present disclosure is not particularly limited thereto, and may be used only as the supply unit 40 or as a control method of the printing apparatus 11.

The supply unit, the printing apparatus, and the method for controlling the printing apparatus according to the present disclosure may be configured as follows. For example, in the supply unit of the present disclosure, the detection member may be formed to have a length in the supply operation direction in which the supply portion moves within a range in which the supply portion does not contact the collection portion. In this supply unit, since the supply unit is driven within a range in which the detection signal from the supply unit detection unit is output, the interference between the members can be easily prevented by the shape of the detection member.

In the supply unit of the present disclosure, the detection member may be disposed in the supply portion that moves in the supply operation direction, the supply portion detection portion may be disposed in a fixing member that does not move in the supply operation direction, or the detection member may be disposed in a fixing member that does not move in the supply operation direction, and the supply portion detection portion may be disposed in the supply portion that moves in the supply operation direction. In addition, the supply unit detection unit is preferably disposed on the fixed member in a relationship in which an output line for outputting a signal, a power supply line, and the like are connected to the supply unit detection unit.

In the supply unit of the present disclosure, the supply unit may include a control unit that controls the drive unit to move the supply unit in the supply operation direction in the passage space in a disturbance region where the collection unit physically interferes with the supply unit, so that the supply unit detection unit detects the state of the detection member. In the supply unit, the components can be prevented from interfering with each other by the control of the control unit.

In the supply unit of the present disclosure including a control unit, the supply unit detection unit may be provided in plurality, the control unit may control the drive unit to move the supply unit in the supply operation direction in the passage space in a state where all of the plurality of supply unit detection units detect the detection member, and the control unit may control the drive unit to stop the continuous movement of the supply unit when one of the plurality of supply unit detection units does not detect the detection member. In this supply unit, more reliable control and more detailed control can be performed by using a plurality of supply section detection sections. Alternatively, the control unit may control the drive unit to move the supply unit in the supply operation direction in the passage space in a state where all of the plurality of supply unit detection units detect the detection member, and may control the drive unit to change the movement direction of the supply unit based on a position of the supply unit detection unit in which the detection member is not detected, when the detection member is not detected by any of the plurality of supply unit detection units.

In the supply unit of the present disclosure including a control unit, the control unit may control the drive unit to move the supply unit in a direction in which the supply unit detection unit detects the detection member, in a state in which the supply unit detection unit does not detect the detection member. In this supply unit, interference between the components can be prevented more reliably. In the supply unit, the control unit may move the supply unit in a direction in which the supply unit detection unit detects the detection member, using the position information of the supply unit.

The printing device of the present disclosure includes: a print head that performs a printing process of a viscous fluid on a printing object using a screen mask; a recovery unit having a recovery member that comes into contact with the screen mask to recover and move the viscous fluid, and a recovery moving unit that moves the recovery member in a predetermined printing direction; a supply unit comprising any one of the above supply units; a supply moving unit that moves the supply unit between a standby area where the supply unit stands by and a supply area where the viscous fluid is supplied; and a control unit that controls the drive unit so that the supply unit moves in the passage space in the supply operation direction and controls the supply moving unit so that the supply unit moves in the interference region, in a state where the supply unit detection unit detects the detection member in the interference region where the collection unit and the supply unit physically interfere with each other in the supply region.

In this printing apparatus, since the supply unit is provided, it is possible to prevent the components of the recovery unit and the supply unit from interfering with each other. Further, the printing apparatus can obtain an effect according to the aspect adopted by any one of the supply units.

In the printing apparatus of the present disclosure, the supply moving unit may be a printing head having a squeegee for moving the viscous fluid on the screen mask to perform the printing process. In this printing apparatus, the supply moving unit of the supply unit also serves as a print head, and therefore the structure can be further simplified.

In the control method of a printing apparatus according to the present disclosure, the printing apparatus includes: a print head that performs a printing process of a viscous fluid on a printing object using a screen mask; a recovery unit having a recovery member that comes into contact with the screen mask to recover and move the viscous fluid, and a recovery moving unit that moves the recovery member in a predetermined printing direction; a supply unit including a supply unit having a mounting unit to which a cartridge accommodating the viscous fluid can be mounted and which releases the mounting of the cartridge, a drive unit which moves the supply unit in a supply operation direction, a detection member which detects whether or not the supply unit is located in a passage space where the recovery unit does not contact the supply unit, based on a position of the detection member, and a supply unit detection unit; and a supply moving unit that moves the supply unit between a standby area where the supply unit stands by and a supply area where the viscous fluid is supplied, wherein the control method includes: in an interference area where the recovery unit and the supply unit physically interfere with each other in the supply area, the drive unit is controlled to move the supply unit in the passage space in the supply operation direction so that the supply unit detection unit detects the detection member, and the supply moving unit is controlled to move the supply unit in the supply area.

In the same manner as the supply unit and the printing apparatus, the method of controlling the printing apparatus can prevent the components of the recovery unit and the supply unit from interfering with each other. In the method of controlling the printing apparatus, various modes of the supply unit and the printing apparatus may be adopted, and steps for realizing the functions of the supply unit and the printing apparatus may be added.
