In order to implement the mode of the invention

Hereinafter, embodiments will be described in detail with reference to the drawings. The following embodiments do not limit the scope of the claims, and all combinations of features described in the embodiments are not necessarily essential to the invention. Two or more of the plurality of features described in the embodiments may be combined as desired. The same or similar components are denoted by the same reference numerals, and redundant description thereof is omitted. In each drawing, the X direction and the Y direction are horizontal directions, and the Z direction is a vertical direction.

< manufacturing System >

Fig. 1 is a plan view schematically showing a manufacturing system 1 according to an embodiment of the present invention. The manufacturing system 1 is a system for manufacturing a rotation assembly by attaching a plurality of mounted members to the rotation main body portion 21. In the present embodiment, the blade 22 (see fig. 2) as the attached member is attached to the rotary body 21. The rotary assembly 2 (see fig. 13B) manufactured by the manufacturing system 1 can be used as a component of an aircraft engine or a turbine generator, for example. In the present embodiment, the manufacturing system 1 includes a table 10 on which a tray 3 accommodating blades 22 is placed; a transfer device 11 for transferring the blade 22; a measuring device 12 for measuring a physical quantity of the blade 22; and a mounting device 13 for mounting the blade 22 to the rotary body 21. In addition, the manufacturing system 1 includes a control device 15 that generally controls these devices. The structure of each device will be described later.

< vane and tray >

Fig. 2 is a perspective view schematically showing the structure of the blade 22. The blade 22 is a mounted member mounted to the rotating main body portion 21 in the manufacturing system 1. For example, the blade 22 is constructed from a heat resistant alloy (e.g., nickel-base superalloy, titanium-aluminum alloy), a Ceramic Matrix Composite (CMC), or the like. In the case of the present embodiment, the blade 22 includes a root portion 221, a flange portion 222, an airfoil portion 223, and an identifier 224.

The root portion 221 is configured to be engageable with the groove 211 of the rotary body 21. The engaged portion 2211 on the lower side of the root 221 engages with the engaging groove 2111 of the groove 211 shown in fig. 13A and 13B, thereby restricting movement of the blade 22 in the radial direction (vertical direction in fig. 13B) and the rotational axis direction (horizontal direction in fig. 13B) with respect to the rotary body 21. The wing portions 223 constitute so-called rotor blades of the rotation assembly 2. Further, flange portion 222 defines the interval between wing portions 223. When the plurality of blades 22 are arranged in parallel in the circumferential direction of the rotary body 21, the flange portions 222 of the adjacent blades 22 are brought into contact with each other, and the interval between the wing portions 223 is maintained at a predetermined value. The identifier 224 is an identifier for identifying each blade 22. As the identifier 224, for example, a two-dimensional code such as a barcode or a QR code (registered trademark) can be used.

Fig. 3 is a perspective view schematically showing the structure of the tray 3. The tray 3 is a receiving member that can receive the blade 22 as a member to be attached. The tray 3 includes a plurality of blade housing portions 31, a held portion 32, and an identifier 33.

The plurality of blade housing portions 31 can house the blades 22, respectively. The plurality of blade housing portions 31 are configured to house the blades 22 one by one in one direction or in a direction intersecting the one direction. The held portion 32 is a portion held by the tray holding portion 111 of the transfer device 11 when the transfer device 11 transfers the tray 3. The identifier 33 is an identifier for identifying each tray 3. As the identifier 33, the same identifier as the identifier 224 can be used. The identifier 33 can be read by a reading unit 115 (described later) of the transfer device 11, and the identifier 33 of the tray 3, the position of the blade housing portion 31, and the identifier 224 of the blade 22 are stored in the tray housing information storage portion 1262a (described later) in association with each other. In addition, the blade housing portion 31 is provided with symbols only in a part thereof, and other symbols are omitted, in view of easy visibility.

< placing stage >

Fig. 4 is a schematic perspective view showing the table 10 of fig. 1. The table 10 is a table for temporarily placing the tray 3 in advance. In the present embodiment, the table 10 includes a mounting member 101 for mounting the tray 3 thereon, and a mounting area of the mounting member 101 is divided into a supply area 102, a standby area 103, and a collection area 104.

The supply area 102 is an area where the tray 3 transferred from the outside of the manufacturing system 1 is placed. That is, in the present embodiment, the tray is supplied to the area where the blade 22 is accommodated in the tray 3. In the supply area 102, a positioning member 1021 for positioning the tray 3 is provided. The positioning member 1021 extends upward from the placing member 101 to a position that greatly exceeds the height of the tray 3 by one amount. This enables the supply area 102 to load a plurality of trays 3. The tray 3 supplied to the supply area 102 may be in an empty state in which the blades 22 are not accommodated.

The standby area 103 is an area for allowing the tray 3 accommodating the blade 22 measured by the measuring device 12 to stand by. The standby area 103 has a space larger than the supply area 102 and the collection area 104 so that a plurality of trays 3 are not mounted and can be placed in parallel in the horizontal direction. In the present embodiment, the standby region 103 may be disposed in a rectangular shape so as to be placed in parallel in the X direction and the Y direction. Thus, the identifier 33 of the tray 3 and the identifier 224 of the blade 22 can be read by the reading unit 115 (described later) of the transfer device 11 located above the tray 3 placed on the standby area 103. Note that, as the tray 3 to be kept on standby in the standby area 103, an empty tray 3 in which the blades 22 are not accommodated in the plurality of blade accommodating portions 31 may be placed.

In the standby area 103, a positioning member 1031 for positioning the tray 3 is provided. Further, the tray 3 accommodating the blade 22 before measurement may be placed on the standby area 103. Here, the positioning member 1031 is marked only on a part thereof in view of easy visibility, and other marks are omitted.

The recovery area 104 is an area where the tray 3 transferred to the outside of the manufacturing system 1 is placed. That is, the tray 3 to be collected is placed on the collection area 104. The tray 3 that has become empty is transferred to the mounting device 13 by the stored blade 22, and is transferred to the collection area 104 by the transfer device 11. The tray 3 placed on the collection area 104 may be in a state in which the blades 22 are accommodated. Further, in the collection area 104, a positioning member 1041 for positioning the tray 3 is provided. Positioning member 1041 extends upward from placing member 101 to a position that greatly exceeds the height of tray 3 by one amount. This enables the supply area 102 to load a plurality of trays 3. Further, by providing the supply area 102 and the recovery area 104, the trays 3 can be sequentially supplied and recovered, and the manufacturing system 1 can be continuously operated.

See also figure 1. In the present embodiment, the measuring device 12 is provided on a first side 103a (right side in fig. 1) of the table 10, and the mounting device 13 is provided on a second side 103b (lower side in fig. 1) different from the first side 103 a. In addition, a portion of a third side 103c (left side in fig. 1) of the table 10, which is different from the first side 103a and the second side 103b, is defined as a supply area 102 and a collection area 104. In this way, the measurement device 12 and the mounting device 13 are disposed adjacent to the standby area 103 of the table 10. The transfer device 11 supplies the area 102, the collection area 104, the measurement device 12, and the mounting device 13 over the area, and transfers the tray 3 or the blade 22 to and from the upper side of each of them. Therefore, the moving distance of the tray 3 and the blade 22 is reduced, and the manufacturing system 1 can efficiently perform manufacturing.

< transfer device >

Fig. 5 is a schematic perspective view of the transfer device 11 in fig. 1. The transfer device 11 is a device for transferring the blade 22 between the table 10 and the measurement device 12 and between the table 10 and the mounting device 13. In the present embodiment, the transfer device 11 is a so-called gantry-type orthogonal robot, and is provided above the table 10, the measurement device 12, and the mounting device 13 so as to be movable in the horizontal direction and the vertical direction. In the present embodiment, the transfer device 11 includes a tray holding unit 111, a blade holding unit 112, a horizontal moving unit 113, a vertical moving unit 114, a reading unit 115, a support unit 117, and a control unit 116 (described later). As the configuration of the transfer device 11, for example, another well-known device such as a vertical articulated robot may be used.

The tray holding portion 111 holds the tray 3. In the case of the present embodiment, the tray holding portion 111 includes a pair of plate-shaped members 1111, 1111 each having a hook portion 1112. By moving these plate-like members 1111 and 1111 in parallel in the direction of separating from each other (the direction of arrow 5A), the hook portions 1112 and 1112 are hooked on the hooked portions (not shown) of the held portion 32 of the tray 3, and the tray 3 is held. The structure in which the tray holding portion 111 holds the tray 3 is exemplified, and another structure such as a structure in which the tray holding portion 111 grips a part of the tray 3 may be adopted.

The blade holding unit 112 (transfer holding means) holds the blade 22. In the case of the present embodiment, 2 blade holding portions 112, 112 are provided, each having a pair of gripping members 1121, 1121 capable of gripping the wing-shaped portion 223 of the blade 22. The blade holding portion 112 holds the blade 22 by moving the pair of gripping members 1121, 1121 in parallel in the direction (the direction of arrow 5B) away from each other by moving the gripping wing-shaped portions 223. In the case of the present embodiment, the 2 blade holding portions 112, 112 can hold the blades 22 one by one.

In the present embodiment, the tray holding portion 111 and the blade holding portion 112 are supported by a support portion 117 provided at the tip (lower end) of the vertically moving portion 114. The support portion 117 includes a fixing portion 117a attached to the tip (lower end) portion of the vertical moving portion 114; and a rotating portion 117b configured to be rotatable with respect to the fixed portion 117 a. In the present embodiment, one of the fixing portions 117a is fixed to the tip (lower end) portion of the vertical moving portion 114, and the other is configured to be able to rotate the rotating portion 117 b. The rotation axis of the rotation unit 117b is an inclined axis Ta inclined downward by 45 degrees with respect to the vertical axis Va of the vertical movement unit 114, and the rotation unit 117b rotates about the inclined axis Ta. The rotating portion 117b is rotatably supported by the fixing portion 117a, and the tray holding portion 111 is formed at one portion inclined by 45 degrees in one direction (horizontal direction) with respect to the inclined axis Ta, and the blade holding portion 112 is formed at the other portion inclined by 45 degrees in the other direction (vertical direction) with respect to the inclined axis Ta.

Therefore, although the pair of gripping members 1121, 1121 is oriented in the horizontal direction in fig. 5, the pivoting portion 117b of the support portion 117 pivots in the direction (arrow 5C) about the tilting axis Ta, so that the positions of the tray holding portion 111 and the blade holding portion 112 are changed, and the lower blade 22 or the tray 3 in the vertical direction of the vertical movement portion 114 can be arbitrarily gripped for transfer depending on the purpose of transfer. In the present embodiment, the transfer device 11 includes 2 blade holding portions 112. This enables the transfer device 11 to efficiently perform the replacement work of the blade 22.

The horizontal moving unit 113 is configured to move the tray holding unit 111 and the blade holding unit 112 in the horizontal direction (X direction and Y direction in the drawing). The horizontal movement portion 113 includes a pair of rail members 1131, 1131 extending in the X direction; 1132 provided astride the pair of rail members 1131, 1131 and movable in the X direction; and a Y moving body 1133 movable in the Y direction on the X moving body 1132.

The pair of rail members 1131, 1131 are provided with an interval in the Y direction and support the X moving member 1132, and define the moving ranges of the tray holding portion 111 and the blade holding portion 112. In the present embodiment, the pair of rail members 1131, 1131 extend in the X direction over the entire area of the table 10 and a part of the measurement device 12, and are provided at intervals in the Y direction so that the entire area of the table 10 and a part of the mounting device 13 are located therebetween. Thus, the tray holding portion 111 and the blade holding portion 112 can be moved over the entire area of the table 10, a part of the measuring apparatus 12, and a part of the mounting apparatus 13.

The X moving member 1132 is configured to move the tray holding portion 111 and the blade holding portion 112 in the X direction. For example, the X moving member 1132 includes a driving source (not shown) such as an electric motor. The X moving member 1132 moves the tray holding portion 111 and the blade holding portion 112 in the X direction by engaging a pinion mechanism coupled to an output shaft of the electric motor with a rack mechanism provided on the rail member 1131.

The Y moving body 1133 is configured to move the tray holding portion 111 and the blade holding portion 112 in the Y direction. For example, the Y moving body 1133 includes a drive source (not shown) such as an electric motor. The Y moving member 1133 moves the tray holding portion 111 and the blade holding portion 112 in the Y direction by engaging a pinion mechanism coupled to an output shaft of the electric motor with a rack mechanism provided in the X moving member 1132. The structures of the X moving object 1132 and the Y moving object 1133 are not limited to the above-described structures, and well-known structures may be employed.

The vertical movement portion 114 is configured to move the tray holding portion 111 and the blade holding portion 112 in the vertical direction (Z direction). For example, the vertical moving unit 114 includes a driving source (not shown) such as an electric motor, and moves the tray holding unit 111 and the blade holding unit 112 in the Z direction by a ball screw mechanism, a rack and pinion mechanism, and the like. The structure of the vertical movement portion 114 is not limited to the above-described structure, and a known structure can be adopted.

The reading unit 115 reads the identifier 33 of the tray 3 and the identifier 224 of the blade 22. This allows the tray 3 and the blade 22 to be transferred and determined.

In the present embodiment, the upper side of the table 10, the upper side of a part of the measuring device 12, and the upper side of a part of the mounting device 13 are the moving ranges of the tray holding portion 111 and the blade holding portion 112 of the transfer device 11, but the moving ranges may be designed appropriately. For example, the entire table 10, the measurement device 12, and the mounting device 13 may be used as the movement range of the tray holding portion 111 and the blade holding portion 112 of the transfer device 11.

In the present embodiment, as will be described later, the transfer device 11 transfers the blade 22 between the platform 10 and the measuring device 12 via the tray 3, and directly transfers the blade 22 between the platform 10 and the mounting device 13. However, the transfer device 11 may be configured to directly transfer the blade 22 between the platform 10 and the measurement device 12, or may be configured to transfer the blade 22 between the platform 10 and the mounting device 13 via the tray 3.

< measuring apparatus >

Fig. 6 is a schematic perspective view of the measurement device 12 of fig. 1, and fig. 7 is a schematic plan view of the measurement device 12. The measuring device 12 is a device for measuring a physical quantity of the blade 22. In the present embodiment, the measurement device 12 is provided adjacent to the stand 10 on the standby area 103 side. In the present embodiment, the measurement device 12 includes a placement unit 121; a robot 122; a rotary table 123; a measurement unit 124; a base portion 125 supporting them; and a control unit 126 (described later).

The mounting unit 121 is provided for waiting for the blade 22 before and after measurement, and includes a mounting table 1211 on which the tray 3 accommodating the blade 22 before and after measurement is mounted; and a positioning mechanism 1212 that performs positioning of the tray 3. In the present embodiment, the mounting table 1211 is provided in the measurement device 12 so as to face the table 10. This reduces the distance between the placing unit 121 and the table 10, thereby enabling efficient transfer of the tray 3.

The positioning mechanism 1212 includes a regulating member for regulating the positions of the four corners of the tray 3; and a displacement unit 1213 that can displace 1 of the restriction member. When the displacement unit 1213 is displaced in the direction of arrow 7A in the figure in a state where the tray 3 is placed on the placement table 1211, the tray 3 abuts against each regulating member, and the position of the tray 3 on the placement table 1211 is determined.

The robot 122 transfers the blade 22 between the placement unit 121 and the rotary table 123. In the present embodiment, the robot 122 is a vertical articulated robot, and a holding portion 1221 capable of holding the blade 22 is provided at the tip end thereof. Thus, the robot 122 can replace the blade 22 supported by the blade support member 1232 (described later) and the different blade 122 at the replacement position N1 on the turntable 123. In the present embodiment, the robot 122 is a vertical articulated robot, but a horizontal articulated robot or another well-known industrial robot may be used.

The rotary table 123 mounts the blades 22 transferred from the mounting portion 121 by the robot 123 one by one, and is provided movably to a measurement unit 124 disposed around the rotary table 123. The blade 22 placed on the rotary table 123 is moved to the measuring devices of the measuring unit 124 by the rotational movement of the rotary table 123, and thus the measurements by the measuring devices are sequentially performed. The rotary table 123 includes a circular plate-like member 1231 rotatably supported; and a plurality of blade support portions 1232 arranged at predetermined intervals on a circle 123r concentric with the shaft 123c that becomes the center of the plate-like member 1231.

The plate-like member 1231 is rotatable about an axis that becomes the center of the plate-like member 1231 in the arrow 7B direction of fig. 7 by a driving mechanism 1235 such as a motor. By intermittently operating the plate-like member 123, the blade support portion 1232 can be moved and stopped at the measurement position by the measurement unit 124. The blade support member 1232 is a support member that supports the blade 22, and a plurality of blade support members are provided, each of which can support the blade 22. In the present embodiment, 8 blade support members 1232 are arranged at equal intervals on the peripheral edge 1236 of the plate-like member 1231. However, the number thereof may be designed appropriately. In addition, the blade support member 1232 is provided with symbols only in a part thereof in view of easy visibility, and other symbols are omitted.

The measurement unit 124 is configured to measure various physical quantities of the blade 22. The measurement unit 124 includes a reader 1241, a dimension measurement device 1242, a weight measurement device 1243, and a temperature measurement device 1244, and these measurement devices are arranged so that the blade 22 supported by the rotary table 123 can be measured. Hereinafter, these may be collectively referred to as the measuring instruments 124 a. The measurement unit 124 includes a transfer mechanism 1245 that transfers the blade between the weight measuring device 1243 and the rotary table 123.

The reader 1241 reads an identifier 224 (for example, a two-dimensional code such as a QR code (registered trademark) or a barcode) given to the blade 22 in advance. Thus, each blade 22 can individually manage various physical quantities to be measured. For example, the reader 1241 is a bar code reader.

Dimension measuring device 1242 measures a dimension measurement portion that becomes dimension L of blade 22 (dimension L in fig. 3) set in advance. The dimension L corresponds to a circumferential dimension when the blade 22 is attached to the rotary body 21. Then, based on the dimension L, the blade 22 attached to the rotating body 21 is selected. For example, sizer 1242 can also include a camera. Further, the dimension measuring device 1242 may take an image of the blade 22 from above with a camera, analyze image data thereof, and calculate the dimension. Further, for example, the size measuring device 1242 may be a laser type length measuring sensor or the like.

Weight measuring device 1243 measures the weight of blade 22. From the viewpoints of high efficiency of the turbine (improvement in gas fluidity, improvement in combustion efficiency, and the like), suppression of vibration, and the like, it is desirable to suppress the positional deviation between the center of gravity of the rotating assembly 2 and the rotation axis thereof when the blades 22 are attached to the rotating body 21. Therefore, the blades 22 need to be arranged in a well-balanced manner in the circumferential direction of the rotary body 21 based on the weight measured by the weight measuring device 1243.

The transfer mechanism 1245 includes a grip portion 1245a for gripping the blade 22, and the blade can be transferred between the weight measuring device 1243 and the rotary table 123 by the grip portion 1245 a. The grip 1245a is movable in the Y direction and the Z direction by a drive source not shown.

Temperature measurement 1244 measures the temperature of blade 22. Thereby, the value of the dimension L can be modified in consideration of the thermal expansion of the blade 22. For example, the temperature measuring device 1244 may be a non-contact infrared radiation thermometer.

In the present embodiment, as shown in fig. 7, the measurement regions P2 to P4 and the reading region P1 of each measurement instrument 124a are located at equal intervals on the movement path of the blade support member 1232. That is, the measurement regions P2 to P4 and the reading region P1 are located at equal intervals along the edge of the plate-like member 1231 of the turntable 123. Therefore, each blade 22 is measured every time the plate-like member 1231 rotates 90 degrees.

In the case of the present embodiment, as described above, 8 blade support members 1232 are arranged at equal intervals along the edge of the plate-like member 1231. When every other 4 of the 8 blade support members 1232 are located at the measurement positions M1 to M4, 1 of the remaining 4 blade support members 1232 located therebetween is located at the replacement position N1. Thus, the robot 122 can replace the blade 22 after measurement (measured) and the blade 22 before measurement (not measured) during the measurement by each measuring instrument. Therefore, the measurement device 12 can perform measurement and replacement of the blade 22 efficiently by rotating and stopping the plate-like member 1231 by 45 degrees each time.

The base portion 125 is provided to support each component of the measuring apparatus 12. The base portion 125 includes a placement support portion 1251 for supporting the placement portion 121; a measurement support 1252 for supporting the measurement unit 124; and a transfer support portion 1253 for supporting the robot 122 for transferring the blade 22. Accordingly, since the relative positions of the placement unit 121, the measurement unit 124, and the robot 122 are already determined, the work can be performed accurately. Further, by arbitrarily setting the heights of the respective support portions, the height of the tray 3 placed on the placement portion 121, the height of the blade support member 1232 provided on the rotary table 123, and the height most suitable for transfer of the blade 22 by the robot 122 are set, and transfer efficiency of the blade 22 can be improved.

< mounting apparatus >

Fig. 8 is a schematic plan view showing the mounting device 13. The attachment device 13 is a device for attaching the blade 22 measured by the measuring device 12 to the rotating body 21. The mounting device 13 is provided adjacent to the standby area 103 of the table 10. This enables the transfer device 11 to efficiently transfer the blade 22 measured by the measuring device 12 to the mounting device 13. The mounting device 13 includes a placement unit 131, a robot 132, a rotating body measuring unit 133, a rotating body support unit 134, and a control unit 135 (described later). Further, the robot includes a base 136 having the placement unit 131, the robot 132, the rotor measurement unit 133, and the rotor support unit 134 integrated therewith.

The mounting portion 131 is configured to mount the blade 22 attached to the rotary body 21. In the present embodiment, the mounting unit 131 is disposed on the table 10 side. This can shorten the moving distance of the transfer device 11 when transferring the blade 22 between the standby area 103 and the placement unit 131, and can efficiently transfer the blade 22.

In the case of the present embodiment, the placing section 131 includes a plurality of conveyance bodies 1311, a moving unit 1312, a limiting unit 1313, and a reading unit 1314. The reading unit 1314 has, for example, the same configuration as the reader 1241 of the measurement device 12, and reads the identifier 224 given to the blade 22 in advance. The reader 1241 is, for example, a barcode reader.

Each of the plurality of carriers 1311 includes a blade mounting portion 1311b on which the blade 22 is mounted, and a protruding portion 1311a for limiting movement of the carrier 1311 by a limiting unit 1313. In addition, the blade support member 1232 is provided with symbols only in a part thereof in view of easy visibility, and other symbols are omitted.

The moving unit 1312 includes a loop-shaped path portion R in which the plurality of conveyance bodies 1311 move cyclically. That is, the plurality of carriers 1311 are mounted on the annular path portion R. For example, the moving means 1312 may be a roller conveyor belt forming the endless path portion R, or may be another conveyor belt or a well-known conveying mechanism.

In the present embodiment, a placement section S1 including the placement position R1 and a mounting section S2 including the removal position R2 are provided in the path portion R of the moving means 1312. The placement section S1 is a section where the transfer device 11 can transfer the blade 22 between the table 10 and the conveyance body 1311. The mounting section S2 is a section in which the robot 132 can transfer the blade 22 mounted on the rotating body 21 between the rotating body 21 and the conveyor 1311. For example, when the reading unit 1314 reads the identifier 224 of the blade 22 at the attachment position R2 and the read identifier 224 matches the identifier 224 of the blade 22 to be attached, the robot 132 may grip the blade 22. The mounting section S1 and the mounting section S2 may be designed appropriately according to the configuration of the transfer device 11 and the robot 132.

The limiting unit 1313 is a unit that limits the movement of the conveyance body 1311 by the moving unit 1312. The restricting unit 1313 restricts movement of the conveyor 1311, for example, when the transfer device 11 places the blade 22 on an empty conveyor 1311, when the robot 132 grips the blade 22 attached to the rotating body 21 from the conveyor 1311, or the like. In addition, the movement of the conveyance body 1311 is also restricted when the reading unit 1314 reads the identifier 224 of the blade 22.

Fig. 9A is a view in the direction of 8B in fig. 8, and shows a state in which the movement of the conveyor 1311 is not restricted by the restricting unit 1313 (a state in which the restricting unit 1313 and the conveyor 1311 are not in contact). Fig. 9B is a view in the direction of 8B in fig. 8, and shows a state in which the restricting unit 1313 restricts the movement of the conveyor 1311 (a state in which the restricting unit 1313 and the conveyor 1311 are in contact). The base 1313b of the restriction unit 1313 supports the restriction member 1313a so as to be displaceable in the vertical direction. When the carrier 1311 is movable (fig. 9A), the restricting member 1313a is displaced upward and positioned on the movement path of the protruding portion 1311a, and the protruding portion 1311a of the carrier 1311 abuts against the restricting member 1313a, thereby restricting the movement of the carrier 1311 (fig. 9B). The configuration of the limiting means 1313 is an example, and another configuration may be adopted. For example, the restriction member 1313a may also be provided so as to be displaceable in a direction perpendicular to the moving direction of the moving unit 1311.

In the present embodiment, the configuration in which the placement unit 131 includes the moving means 1312 has been described as an example, but the placement unit 131 may not include the moving means 1311. For example, the carrier may be a self-propelled carrier constituting a driving mechanism for movement.

Refer to fig. 10 and 11 together. Fig. 10 is a view in the direction 8A of fig. 8, and fig. 11 is a view in the direction 8A, showing only the rotary body 21. In the case of the present embodiment, the rotary body 21 is supported by the rotatable rotary body support portion 134, and the rotary body measuring portion 133 is provided so that the physical quantity of the rotary body 21 can be measured.

Here, the rotary body 21 will be described. The rotary body 21 constitutes a main body of the rotary assembly 2 (see fig. 13B), and rotates about the rotation axis Z1. In the present embodiment, the rotary body 21 includes a circumferential surface, and the circumferential surface is provided with mounting portions M1 to M3 to which the blades 22 are mounted. In the case of the present embodiment, the mounting portions M1-M3 are grooves formed continuously on a circumference set around the rotation axis Z1. Although the mounting portion M1 is described below as an example, the rotary member measuring portion 133 can perform the same measurement as the mounting portions M2 and M3. In addition, in the case where the mounting portions M1 to M3 are not particularly distinguished, there is a case where they are simply referred to as mounting portions M. In the present embodiment, the case where the rotating assembly 2 includes the mounting portions M1 to M3 as an integral structure is described as an example, but the rotating assembly 2 is not limited to this. For example, the rotation assembly may be configured by combining a disk body having a hole in the center thereof through which the rotation shaft body is inserted. Specifically, the rotary body 22 may be configured such that mounting portions M2, M1, and M3 including insertion ports 2112 (described later) are formed on the outer peripheries of the 3 disk bodies, respectively, and the rotary shaft bodies are fitted into the respective holes of the 3 disk bodies.

The rotating body measuring unit 133 performs measurement related to the rotating body 21. In the present embodiment, the rotating body measuring unit 133 includes a circumferential length measuring unit 1330 and a gap measuring unit 1335.

The circumferential length measuring section 1330 measures a physical quantity related to the circumferential length of the mounting section M1 of the rotary body 21. In the present embodiment, the mounting portion M1 is a groove formed in the circumferential direction of the rotary body 21, and the circumferential length measuring section 1330 measures the diameter D1 of the groove. From the measurement results, the circumferential length of the mounting portion M1 was calculated. The circumference measurement unit 1330 includes camera units 1331a and 1331b and illuminations 1332a and 1332 b. The camera units 1331a and 1331b are provided with a moving mechanism that moves the respective cameras in an axial direction (height direction) parallel to the rotation axis Z1. This allows the moving mechanism to move the respective cameras to the position optimum for imaging (measurement) of the mounting portion M, and to perform imaging (measurement). Further, by moving the respective cameras in the axial direction, the cameras can be moved to the positions optimum for imaging (measurement) of the mounting portions M2 and M3 having different heights in the axial direction, and the diameters of the respective grooves can be measured. The height in the axial direction can be calculated and obtained by setting a reference of the moving mechanism with reference to a mounting surface on which the rotation support portion 134 of the rotating body 21 is mounted, for example.

The camera units 1331a, 1331b can capture images of both ends of the rotary body 21 when the mounting portion M1 is viewed from the side, as shown in fig. 10. In other words, the camera unit 1331a captures an image of a portion of the mounting portion M1 when viewed from the side, and acquires information regarding the position thereof. The camera unit 1331b images the other portion of the circumference of the groove of the mounting portion M1, which is at a position symmetrical to the rotation axis Z1 of the rotary body 21, and acquires information about the position. Then, the distance of the diameter D1 is calculated based on the acquired positions of the one portion and the other portion.

The illuminations 1332a, 1332b are provided to face the camera units 1331a, 1331b, respectively, and illuminate the imaging ranges of the camera units 1331a, 1331b from the facing sides, respectively. The illumination 1332a, 1332b may be LED illumination, for example. By irradiating the camera units 1331a and 1331b with light from the light sources in the opposite directions by the illuminations 1332a and 1332b, the ridge line of the rotor body portion 21 supported by the rotor support portion 134 disposed therebetween can be made clear.

See also figure 12. Fig. 12 is a view schematically showing the mounting portion M1 in a state where the blade 22 is mounted. The gap measuring section 1335 measures the arrangement of the blades 22 attached to the mounting section M1. For example, the gap measuring section 1335 measures a physical quantity related to the gap between the mounted members. In the present embodiment, the clearance measuring section 1335 measures the clearance amount g between the blade 22c that is first attached (the 2 nd blade 22 from the top in fig. 12) and the blade 22 that is finally attached (the 3 rd blade 22 from the top in fig. 12) after an arbitrary number of blades 22 have been attached along the attachment section M1.

The gap measurement unit 1335 includes a camera unit 1336 and illumination 1337. The camera unit 1336 includes a moving mechanism for moving the camera in an axial direction parallel to the rotation axis Z1. The camera unit 1336 captures (measures) the gap amount g, and calculates the gap amount g by analyzing the captured image. The illumination 1337 illuminates the shooting area of the camera unit 1336. For example, illumination 1337 may also be LED illumination. The camera unit 1336 includes a moving mechanism for moving the camera in an axial direction parallel to the rotation axis Z1. The moving mechanism can thereby move the camera to an imaging position optimum for measurement of the physical quantity relating to the gap between the mounted members and perform imaging. Further, by moving the camera in the axial direction, the gap amount g can be measured by imaging at an optimum position for measuring the physical amount related to the gap between the members to be attached of the blades 22 attached to the attachment portions M2 and M3 having different heights in the axial direction. The height in the axial direction can be calculated and obtained by setting a reference of the moving mechanism with reference to a mounting surface on which the rotation support portion 134 of the rotating body portion 21d is mounted, for example.

In the present embodiment, the configurations of the circumferential length measuring section 1330 and the gap measuring section 1335 are exemplified, and for example, the circumferential length and the gap may be measured by a laser type length measuring sensor or the like. In addition, other well-known measurement methods may be used.

The robot 132 mounts the blade 22 to the rotating body 21. In the present embodiment, the robot 132 is a vertical articulated robot having the same configuration as the robot 122 of the measurement device 12, but may be another well-known industrial robot.

Here, the blade 22 is mounted by the robot 132. Fig. 13A and 13B are referred to together with fig. 11. Fig. 13A is a sectional view taken along line I-I of fig. 11, and is a schematic view showing a state in which the blade 22 is inserted into the insertion port 2112 of the mounting portion M. Fig. 13B is a sectional view taken along line II-II of fig. 11, and shows a state in which the blade 22 is inserted into the mounting portion M and engaged (mounted state). In the case of the present embodiment, the robot 132 inserts the blade 22 from the insertion port 2112 of the mounting portion M (fig. 13A) and slides in the circumferential direction, so that the blade 22 at the position of the insertion port 2112 moves to a position offset in the circumferential direction (fig. 13B). By repeating this operation in sequence, the robot 132 completes the mounting of all the blades 22 to the mounting portion M. At this time, if the respective blades 22 are arranged close to each other, the last blade 22 and the first blade 22 are adjacent to each other when the last blade 22 is attached. The circumference of the mounting portion M of the rotating main body portion 22 is set so that some clearance is generated between the two blades 22. The gap measuring section 1335 measures the gap amount g of some of the gaps.

The base portion 136 supports each component of the mounting device 13. A support arrangement portion 1361 for arranging the rotor support portion 134 is provided in the base portion 136; a circumferential length measurement arrangement unit 1362 for arranging and supporting the circumferential length measurement unit 1330; and a gap measurement arrangement portion 1363 for arranging and supporting the gap measurement portion 1335. Since these are integrally provided at an arbitrary height on the base portion 136, the relative positions thereof can be specified, and accurate measurement can be performed by the circumferential length measuring section 1330 and the gap measuring section 1335. Moreover, the movement of the blade 22 between the conveyor 1311 and the rotor body 21 by the robot 132 can be performed efficiently.

< control Structure >

Fig. 14 is a schematic diagram showing the hardware configuration of the entire manufacturing system 1. In the present embodiment, the control device 15 is connected to each of the transfer device 11, the measurement device 12, and the mounting device 13, and controls the operation of the entire manufacturing system 1. The control device 15 includes a processing unit 151, a storage unit 152, and an interface unit 153, which are connected to each other by a bus 154.

The processing unit 151 is a processor represented by, for example, a CPU, and executes a program stored in the storage unit 152. The storage unit 152 includes, for example, a RAM (memory), a ROM (read only memory), a hard disk, and stores various data in addition to the program executed by the processing unit 152. The interface unit 153 is provided between the processing unit 151 and an external device, and is, for example, a communication interface or an I/O (input/output) interface. The host computer 4 is a control device that manages and controls the entire production facility in which the manufacturing system 1 is installed.

Fig. 15 is a schematic diagram showing a hardware configuration of the transfer device 11. In the present embodiment, the control unit 116 is connected to other elements constituting the transfer device 11, and controls the operation of the transfer device 11. The control unit 116 includes a processing unit 1161, a storage unit 1162, and an interface unit 1163, which are connected to each other by a bus 1164.

The processing unit 1161 is a processor represented by, for example, a CPU, and executes a program stored in the storage unit 1162. The storage unit 1162 includes, for example, a RAM (memory), a ROM (read only memory), a hard disk, and the like, and stores various data in addition to the program executed by the processing unit 1161. The interface unit 1163 is provided between the processing unit 1161 and an external device (such as the control device 15), and is, for example, a communication interface or an I/O (input/output) interface.

The processing unit 1161 can communicate with the control device 15 via the interface unit 1163, and can operate the respective elements of the transfer device 11 in response to an instruction from the control device 15. For example, when there is an instruction to transfer the tray 3 in the supply area 103 to the placement unit 121 of the measurement device 12, the processing unit 1161 operates the horizontal movement unit 113 and the vertical movement unit 114 to move the tray holding unit 111, hold the tray 3, and transfer the tray 3 to the placement unit 121.

In the case of the present embodiment, the storage part 1162 includes a tray position information storage part 1162a as a storage area in which data can be stored. The tray position information storage 1162a is a storage area for managing the position where the tray 3 is placed, and includes "tray identification information" and "position information" as stored information.

The "tray identification information" is information for identifying each tray 3. For example, the processing unit 1161 reads the identifier 33 of the tray 3 by the reading unit 115 of the transfer device 11, and obtains "tray identification information". The "position information" is information indicating where the tray 3 is placed on the manufacturing system 1. For example, the position information is assigned to each placement position of the standby area 103 of the table 10, the supply area 102, the collection area 104, the placement portion 121 of the measurement device 12, and the like. When the tray 3 is placed at any one of the placement positions, the processing unit 1161 stores the "tray identification information" in the tray position information storage unit 1162a in association with the "position information" of the place where the tray 3 is placed. Thus, the tray position information storage 1162a can manage the position of each tray 3.

Fig. 16 is a schematic diagram showing the hardware configuration of the measurement device 12. In the present embodiment, the control unit 126 is connected to each element of the measurement device 12, and controls the operation of the measurement device 12. The control unit 126 includes a processing unit 1261, a storage unit 1262, and an interface unit 1263, which are mutually connected by a bus 1264.

The processing unit 1261 is a processor represented by, for example, a CPU, and executes a program stored in the storage unit 1262. The storage unit 1262 includes, for example, a RAM (memory), a ROM (read only memory), a hard disk, and the like, and stores various data in addition to the program executed by the processing unit 1261. The interface unit 1263 is provided between the processing unit 1261 and an external device (such as the control device 15), and is, for example, a communication interface or an I/O (input/output) interface.

The processing unit 1261 can communicate with the control device 15 via the interface unit 1263, and operates the respective elements of the measurement device 12 in response to an instruction from the control device 15. When there is an instruction from the control device 15 to measure the physical quantity of the blade 22 placed on the placement unit 121, the processing unit 1261 causes the robot 122 to sequentially transfer the blades 22 from the tray 3 placed on the placement unit 121 to the rotary table 123. The processing unit 1261 intermittently rotates the rotating table 123 and moves and stops the blade 22 to the measurement position of the measurement unit 124. Then, the measurement unit 124 measures the blade 22 moved to the measurement position. Further, if the tray 3 is transferred to the mounting portion 121 by the transfer device 11, the processing unit 1261 operates the positioning mechanism 1212 to position the tray 3.

The storage unit 1262 includes a tray storage information storage unit 1262a and a blade information storage unit 1262b as a storage area in which data can be stored.

The tray storage information storage portion 1262a is a storage area for managing information of the blades 22 stored in the tray 3, and includes "tray identification information" (described above), "storage symbol", and "blade identification information" as stored information.

The "housing symbol" is a symbol that is assigned to each of the plurality of blade housing portions 31 in the tray 3, and is information for identifying which blade housing portion 31 of the tray 3a certain blade 22 is housed in. Further, "blade identification information" is information for identifying each blade 22. For example, the control unit 1261 causes the reader 1241 to read the identifier 224 of the blade 22, thereby acquiring "blade identification information". The processing unit 1261 can manage the blades 22 stored in the tray 3 by storing the "storage symbol" and the "blade identification information" in the tray storage information storage unit 1262a in association with each other.

The blade information storage unit 1262 is a storage area for managing measurement information of each blade, and includes "blade identification information" (described above) and "measurement information" as stored information.

The "measurement information" is information related to the physical quantity of the blade 22 measured by the measurement device 12. In the present embodiment, the "measurement information" includes the weight, size, and temperature of each blade 22. The processing unit 1261 can manage the physical quantities of the respective blades 22 by storing them in the blade information storage unit 1262b in association with the "blade identification information".

Fig. 17 is a schematic diagram showing a hardware configuration of the mounting device 13. In the present embodiment, the control unit 135 is connected to each element of the mounting device 13 and controls the operation of the mounting device 13. The control unit 135 includes a processing unit 1351, a storage unit 1352, and an interface unit 1353, which are mutually connected by a bus 1354.

The processing unit 1351 is a processor represented by, for example, a CPU, and executes a program stored in the storage unit 1352. The storage portion 1352 includes, for example, a RAM (memory), a ROM (read only memory), a hard disk, and stores various data in addition to the program executed by the processing portion 1351. The interface portion 1353 is provided between the processing portion 1351 and an external device (such as the control device 15), and is, for example, a communication interface or an I/O (input/output) interface.

The processing unit 1351 can communicate with the control device 15 via the interface unit 1353, and can operate each element of the attachment device 13 in response to an instruction from the control device 15. For example, when there is a request to acquire information on the circumferential length of the rotary body 21 from the control device 15, the circumferential length measuring unit 1330 is caused to measure the circumferential length of the rotary body 21. When there is an instruction to attach the blade from the control device 15, the robot 132 is caused to attach the blade 22 based on information stored in the arrangement information storage portion 1352b (described later). After the mounting, the gap measuring section 1335 measures the gap and determines the state of the gap.

In the present embodiment, the storage portion 1352 includes an attachment portion information storage portion 1352a, an arrangement information storage portion 1352b, and a gap information storage portion 1352c as storage areas in which data can be stored. The mounting portion information storage portion 1352a is a storage area for managing information of the mounting portion M of the rotating body portion 21, and includes "mounting portion identification information", "circumferential length", and "height" as stored information and the like.

The "mounting part identification information" is information for identifying each mounting part M. The "circumferential length" is the circumferential length of the mounting portion M measured by the circumferential length measuring section 1330 of the mounting device 13. The "height" is the height of the mounting portion M measured by the circumferential length measuring section 1330. The processing unit 1351 stores the information in the mounting unit information storage unit 1352a in association with each other, thereby managing the information for each mounting unit M of the rotating body 21.

The arrangement information storage portion 1352b is a storage area for managing the installation information of the arrangement of the blades 22 installed in the installation portion M, and includes "arrangement information", "arrangement position", and "blade identification information" (described above) as the stored information. The "arrangement position" is information on the position of the blade 22 in the circumferential direction of the mounting portion M. For example, the "arrangement position" may be a relative position with respect to the insertion port 2112, or may be an attachment number. The "arrangement information" is information on each arrangement position of which blade 22 is attached to the attachment portion M, and the "blade identification information" and the "arrangement position" are associated with each other. Thus, the arrangement information storage portion 1352b can manage which blade 22 is arranged at which position of the mounting portion M.

The clearance information storage portion 1352c is a storage area for managing the clearance of the adjacent blade 22 after the blade 22 is attached to the attachment portion M, and includes "attachment portion identification information" (described above), "arrangement information", "clearance", and "determination result" as stored information.

The "gap" is a gap between the adjacent blades 22 measured by the gap measuring section 1335 of the mounting device 13. The "determination result" is a determination result of whether or not the measured gap amount g of the gap is within a range of a preset allowable value. By storing them in association with "configuration information", it is possible to gradually accumulate information as to whether the configuration of the blade 22 is appropriate.

The 9 storage unit 152 of the control device 15 may store information stored in each of the storage unit 1162 of the transfer device 11, the storage unit 1262 of the measurement device 12, and the storage unit 1352 of the mounting device 13. Further, various information may be stored in the host computer 4 by communication between the control device 15 and the host computer 4. In this case, the processing unit 151 of the control device 15 may request data from each device, and the processing unit of each device may transmit the target data to the processing unit 151 based on the request of the processing unit 151 of the control device 15. Similarly, the control device 15 can communicate with the host computer 4 to transmit and receive data to and from the target.

< operation of System >

Fig. 18 is a flowchart showing an example of the process of mounting the blade 22 by the manufacturing system 1. Each step is realized by operating any one or a plurality of devices constituting the manufacturing system 1 based on an instruction from the processing unit 151. For example, the flowchart starts when the tray 3 is transferred from the outside of the manufacturing system 1 to the supply area 102 of the table 10.

In S1801, the transfer device 11 transfers the trays 3 placed on the supply area 102 based on the instruction from the processing unit 151. At this time, the transfer device 11 transfers the tray 3 based on the processing of fig. 19. If it is confirmed that the transfer device 11 has transferred the tray 3 to the placement unit 121, the processing unit 151 proceeds to S1802.

In S1802, the measurement device 12 measures the blade 22 in the storage tray 3 based on an instruction from the processing unit 151. As for details, this is illustrated by fig. 20. If it is confirmed that the measurement by the measurement device 12 is completed, the processing unit 151 proceeds to the processing of S1803.

In S1803, the transfer device 11 transfers the tray 3 placed on the placement unit 121 with the measured blade 22 stored therein to the standby area 103 based on the instruction from the processing unit 151. If it is confirmed that the transfer device 11 has transferred the tray 3 to the standby area 103, the processing unit 151 proceeds to S1804.

In S1804, the attachment device 13 attaches the blade 22 based on the instruction from the processing unit 151. In this step, the circumferential length of the rotary body 21 is measured, the attached blade 22 is selected, and the selected blade 22 is transferred, but details thereof will be described with reference to fig. 20.

At 1805, the transfer device 11 transfers the empty tray 3 to the collection area 104 based on an instruction from the processing unit 151. The processing unit 151, if confirming that the transfer by the transfer device 11 is completed, ends the flowchart.

In the above description, although the series of flows has been described with a focus on one of 1 tray 3, the processing for the next tray 3 may be performed before all the processing for 1 tray 3 is completed. That is, while the blade 22 is being attached by the attachment device 13, the measurement device 12 may perform the respective processes in parallel so as to measure the next blade 22. This enables efficient mounting work.

Fig. 19 is a flowchart showing details of the processing in S1801, and is a flowchart showing an example of the processing in the processing unit 1161 of the transfer device 11. For example, the flowchart is realized by the processing unit 1161 of the transfer device 11 reading and executing the program stored in the storage unit 1162. For example, in the present flowchart, if the tray 3 is supplied to the supply area 104 from outside the manufacturing system 1, the processing unit 1161 of the transfer device 11 receives a transfer instruction from the processing unit 151 of the control device 15, and then the process is started.

In S1901, the processing unit 1161 checks whether another tray 3 is placed on the placing unit 121 to be transferred. When another tray 3 is placed on the placement portion 121, the process proceeds to S1902, and the tray 3 is transferred to the standby area 103, and the process proceeds to S1903. The processing in S1902 may not be executed depending on the states of the standby area 103 and the placement unit 121 (see the broken line in fig. 19). At this time, the processing unit 1161 may read the identifier 33 of the tray 3 by the reading unit 115, and store the identification information of the tray 3 and the position information of the position where the tray 3 is placed in the tray position information storage unit 1162 a. On the other hand, if no other tray 3 is placed on the placement portion 121, the process proceeds to S1905, where the tray 3 is transferred to the placement portion 121, and the process proceeds to S1906.

In S1903, the processing unit 1161 again confirms whether another tray 3 is placed on the placing portion 121 serving as the transfer destination. That is, the processing unit 1161 checks whether the mounting unit 121 is empty. When no other tray 3 is placed on the placement portion 121, the process proceeds to S1904, and the processing unit 1161 transfers the tray 3 to the placement portion 121, and the process proceeds to S1906. Note that, in the processing of S1904, if the processing of S1902 is not omitted, the tray 3 is transferred from the standby area 103 to the placement unit 121 in S1901, and the tray 3 is transferred from the supply area 104 to the placement unit 121 when the processing of S1902 is performed. On the other hand, when another tray 3 is placed on the placement portion 121, the process of S1903 is repeated.

In S1906, the processing unit 1161 transmits information to the effect that the tray 3 has been transferred to the placement unit 121 to the control device 15, and the flowchart ends. At this time, the processing unit 1161 may collectively transmit the identification information of the trays 3 to the control device 15.

< operation of measuring apparatus >

Fig. 20 is a flowchart showing details of the process of S1802, and is a flowchart showing an example of the process of the processing unit 1261 of the measurement device 12. For example, the flowchart is realized by the processing unit 1261 of the measurement apparatus 12 reading and executing a program stored in the storage unit 1262. For example, in the present flowchart, the processing unit 1261 starts when it receives a measurement instruction from the processing unit 151 of the control device 15.

In S2001, the processing unit 1261 transfers the blade 22 to the rotary table 123 by the robot 122. In the present embodiment, the robot 122 transfers the blade 22 to the support 1232 of the rotation number 123.

In S2002 to S2005, the processing unit 1261 reads the identifier 224 by the reader 1241, measures the size by the size measuring device 1242, measures the weight by the weight measuring device 1243, and measures the temperature by the temperature measuring device 1244, respectively. At this time, the processing unit 1261 moves the blade 22 to the reading position and each measurement location every time the rotating table 123 rotates by a predetermined angle.

In S2006, the processing unit 1261 generates and stores the blade information to be stored in the blade information storage unit 1262b based on the acquired blade identification information and the measurement information. Specifically, the information measured in S2002 to S2005 is temporarily stored in a predetermined storage unit each time, and the blade information is completed in S2006.

In S2007, the processing unit 1261 checks whether or not an unmeasured blade 22 is present in the tray 3. When there is an unmeasured blade 22, the processing unit 1261 proceeds to S2008, and after the measured blade 22 mounted on the rotating table 123 is replaced with the unmeasured blade 22 stored in the tray 3 by the robot 122, returns to S2002. On the other hand, if there is no unmeasured blade 22, the processing unit 1261 proceeds to S2009, transfers the blade 22 placed on the turntable 123 to the tray 3 on the placement unit 121, and proceeds to S2010.

In S2010, the processing unit 1261 generates information to be stored in the tray storage information storage unit 1262a based on the identification information of the tray 3 and the identification information of the blade 22. Then, in S2011, the processing unit 1261 requests the control device 15 to transfer the tray 3, and ends the processing.

In the above example, the operation of the measuring apparatus 12 was described focusing on 1 blade 22, but the processing may be performed in parallel for a plurality of blades 22.

< operation of mounting apparatus >

Fig. 21 is a flowchart showing details of the process of S1804, and is a flowchart showing an example of the process of the processing unit 1351 of the mounting apparatus 12. For example, the flowchart is realized by the processing unit 1351 of the measurement apparatus 12 reading and executing a program stored in the storage unit 1352. For example, the flowchart starts if the processing unit 1351 receives an installation instruction from the processing unit 151 of the control device 15.

In S2101, the processing unit 1351 measures the circumferential length of the rotating body 21 by the circumferential length measuring unit 1330. Then, in S2102, the processing unit 1351 acquires information stored in the tray storage information storage unit 1262a and the blade information storage unit 1262b in the measurement device 12 via the control device 15.

In S2103, the processing unit 1351 generates the arrangement information. The processing unit 1351 determines the selection and arrangement of the blades 22 to be attached, based on the circumferential length of the rotating body 21 and the measured size and weight of each blade 22. For example, the processing unit 1351 selects and arranges the blades so that the displacement of the center of gravity is small after the installation and the gap amount g of the gap after all the blades 22 are installed is an allowable value. The processing in S2103 is performed based on the information received by the host computer 4 after receiving the information prepared in advance. In S2104, the selected blade 22 is requested to the control unit 15 so as to be transferred to the mounting unit 131.

In S2105, the processing unit 1351 checks whether or not the blade 22 to be mounted is mounted on the mounting unit 131. The processing unit 1351 proceeds to S2106 when the blade 22 to be attached is mounted, and repeats the processing of S2105 until the mounting is stopped when the blade is not mounted.

Here, for example, if the processing unit 151 of the control device 15 receives the transfer request of S2104 from the processing unit 1351, it instructs the transfer device 11 to transfer the target blade 22 to the placement unit 131. The transfer device 11 transmits transfer completion information to the processing unit 151 if transfer of the blade 22 is completed. Then, if the transfer completion information is received, the processing unit 151 transmits information indicating that the transfer operation of the blade 22 is completed to the processing unit 1351 of the mounting apparatus 13. Upon receiving this information, the processing unit 1351 confirms that the blade 22 is mounted in S2103.

In S2106, the processing unit 1351 attaches the blade 22 to the rotating body 21 by the robot 132. The processing unit 1351 sequentially attaches the blades 22 based on the generated arrangement information, and proceeds to S2107 if the attachment is completed.

In S2107, the processing unit 1351 performs gap measurement by the gap measurement unit 1335. In the present embodiment, the gap amount g of the gap between the first attached blade 22 and the last attached blade 22 is measured. After the measurement, the processing unit 1351 proceeds to the process of S2108.

In S2108, the processing unit 1351 checks whether or not the gap amount of the gap measured in S2107 is within the allowable range. If the allowable value is out of range, the processing unit 1351 replaces the blade 22 with the robot 132 in S2109, and returns to S2107. On the other hand, if the allowable value is within the range, the processing unit 1351 proceeds to S2110, and the rotary assembly 2 is taken out from the rotary support 134 by a transfer means not shown, and the processing is terminated. When there are a plurality of mounting portions M in the rotary body 21, the rotary assembly 2 is removed after the mounting of the blades 22 to all the mounting portions M is completed.

As described above, according to the manufacturing system 1 of the present embodiment, the blades 22 can be automatically attached to the rotary body 21 without depending on the operator, and the rotary assembly 2 can be efficiently manufactured. Further, according to the measuring apparatus 12 of the present embodiment, since the measurement can be performed by the measuring unit 124 while the blade 22 is placed on the placing section 121 and is in standby, the measurement of the blade 22 can be performed efficiently. Further, according to the mounting device 13 of the present embodiment, the appropriate blade 22 can be mounted based on the circumferential length of the rotary body 21.

< other embodiment >

In the above embodiment, the blade 22 is transferred in a flow such as the platform 10, the measurement device 12, the platform 10, and the attachment device 13, but the blade 22 may be transferred from the measurement device 12 to the attachment device 13 without passing through the platform 10. That is, the transfer device 11 may directly transfer the blade 22 whose measurement has been completed by the measurement device 12 to the mounting device 13.

In the above embodiment, the robot 132 of the mounting device 13 is inserted into the blades 22 in order from the insertion port 2112 of the rotating body 21. However, the blade 22 may be attached from any position of the attachment portion M.

Fig. 22 is a schematic perspective view showing a blade 50 according to another embodiment. The blade 50 is configured such that the transverse width length L2 of the root 501 is shorter than the groove width of the mounting portion M. Thereby, the blade 50 shown in fig. 22 can be inserted into the groove of the mounting portion M in the insertion direction of the arrow Id. After the blade 50 is inserted, the blade 50 can be attached to the attachment portion M in the correct direction by rotating the blade 50 by 90 degrees in the rotation direction of the arrow Rd. That is, the engaged portion 5011 on the lower side of the root 501 of the blade 50 engages with the engagement groove 2111 (see fig. 13B) of the mounting portion M.

According to the blade 50 of the present embodiment, the attachment device 13 can attach the blade 50 from an arbitrary position of the attachment portion M while rotating the rotor support portion 124. Therefore, it is not necessary to form the insertion port 2112 (see fig. 11) in the mounting portion M.

As described above, in the embodiment of the present invention, the manufacturing system 1 used when the blades 22 and 50 are attached to the groove of the rotating body 21 to manufacture the rotating assembly 2 has been described, but the present invention is not limited to this. For example, the present invention may be used as a disassembly system for disassembling the blades 22 and 50 from the rotating assembly 2 to which the blades 22 and 50 are attached, or may be used as an inspection system for replacing a worn blade 22 or 50 with a new blade 22 or 50.

The present invention is not limited to the above-described embodiments, and various modifications and changes can be made within the scope で of the present invention.
