Description

[Technical field]

[0001] The present invention relates to a component replacement system that collects and replenishes component suppliers in a component supply unit, and a component mounting system including the same. [Background technology]

[0002] The component mounting system includes a component mounter that mounts components on a substrate such as a printed circuit board. The component mounter includes a component supply unit in which a plurality of component supply tools such as feeders that supply components are arranged, and a head unit that mounts the components supplied by the component supply tools onto the substrate. In the component mounter, a component supply tool that has run out of components or the like is collected from the component supply unit, and a new component supply tool is replenished to the component supply unit in response to the collection.

[0003] Patent Document 1 discloses a supplying device that supplies a component supplying tool to a component mounter in response to collection of the component supplying tool from the component mounter. The supplying device includes a traveling body that travels between a component storage and the component mounter, a moving platform that is movably provided on the traveling body, and a supplying unit mounted on the moving platform. When the supplying device is positioned so as to face the component storage by the traveling body, an operator transfers the component supplying tool from the component storage to the supplying unit. As a result, a plurality of component supplying tools of different component types are arranged in the supplying unit. In this state, when the supplying device is positioned so as to face the component supplying unit of the component mounter by the traveling body, the component supplying tool is exchanged between the component supplying unit and the supplying unit while the moving platform is moving.

[0004] In the supply device disclosed in Patent Document 1, when a part supply tool is transferred from a part storage to a supply unit, the arrangement of the multiple part supply tools in the supply unit is not taken into consideration. Therefore, when multiple part supply tools are arranged in the supply unit, the movement amount of the moving platform may increase when the part supply tool is replaced between the part supply unit and the supply unit. In this case, there is a risk that the efficiency of replacing the part supply tools in the part supply unit may decrease. [Prior art documents] [Patent documents]

[0011] Hereinafter, a component replacement system and a component mounting system according to an embodiment of the present invention will be described with reference to the drawings.

[0012] [Overall configuration of component mounting system] The component mounting system 1 shown in FIG. 1 is a system for producing a component mounting board in which components such as electronic components are mounted on a board such as a printed circuit board. The component mounting system 1 includes a production system 2 and a component replacement system 3. The production system 2 includes a production management device 2A and at least one component mounter 2B. In the production system 2, the production management device 2A and the component mounter 2B are connected to each other so that data can be communicated. The component replacement system 3 includes a storage management device 4A, at least one storage device 4, an exchange management device 5A, and at least one component replacement device 5. In the component replacement system 3, the storage management device 4A and the storage device 4 are connected to each other so that data can be communicated, and the exchange management device 5A and the component replacement device 5 are connected to each other so that data can be communicated. In addition, the component mounting system 1 includes an integrated management device 1A that is connected to each of the production management device 2A, the storage management device 4A, and the exchange management device 5A so that data can be communicated. The integrated management device 1A, the production management device 2A, the storage management device 4A, and the exchange management device 5A are each configured by, for example, a microcomputer.

[0013] In the component mounting system 1, production plan data D1 is transmitted from the integrated management device 1A to the production management device 2A. When the production management device 2A receives the production plan data D1, the component mounter 2B produces component mounting boards in accordance with the production plan data D1. The production management device 2A manages the production of component mounting boards by the component mounter 2B. The production management device 2A transmits production status data D2 indicating the status of production of component mounting boards by the component mounter 2B to the integrated management device 1A.

[0014] Based on the production status data D2 transmitted from the production management device 2A, the integrated management device 1A recognizes the expected time of component shortage associated with the production of component mounting boards in the component mounter 2B, the type of components that have run out, etc. Then, based on the recognition result, the integrated management device 1A generates supply plan data D3 indicating a supply plan for components to the component mounter 2B. The integrated management device 1A transmits the generated supply plan data D3 to each of the storage management device 4A and the exchange management device 5A.

[0015] When the storage management device 4A receives the supply plan data D3, the worker prepares component supply tools for supplying components used in the component mounter 2B based on the supply plan data D3. The worker replenishes the prepared component supply tools in the storage device 4. The storage device 4 stores multiple component supply tools of different component types in a state where they are arranged in a predetermined direction. The storage management device 4A manages the storage status of the component supply tools in the storage device 4.

[0016] When the replacement management device 5A receives the supply plan data D3, the component replacement device 5 takes in the component supply tool from the storage device 4 and replaces the component supply tool with the component mounter 2B. The replacement management device 5A manages the operation of the component replacement device 5.

[0017] [Detailed configuration of the production system] As described above, in the production system 2, when the production management device 2A receives the production plan data D1 transmitted from the integrated management device 1A, the component mounter 2B produces component mounting boards according to the production plan data D1. This component mounter 2B will be described with reference to FIG. 2. In the following, the directional relationship will be described using XYZ orthogonal coordinate axes. The X-axis direction and the Y-axis direction are mutually orthogonal on the horizontal plane, and the Z-axis direction is a direction extending vertically and orthogonal to both the X-axis direction and the Y-axis direction.

[0018] The component mounter 2B is a device that mounts components on a board to produce a component-mounted board. A solder paste pattern is printed on the board before the component is mounted by the component mounter 2B. The component mounter 2B includes a mounter main body 21, a transport conveyor 22, a component supply unit 23, and a head unit 26.

[0019] The mounter body 21 is a housing having an internal space in which each part constituting the component mounter 2B is disposed. The transport conveyor 22 extends in the Y-axis direction and is disposed in a substantially central region inside the mounter body 21. The transport conveyor 22 transports the board in the Y-axis direction. The head unit 26 mounts components on the board transported by the transport conveyor 22. The head unit 26 takes out components from the feeder 25 disposed in the component supply unit 23, and mounts the taken-out components on the board. The head unit 26 is equipped with a plurality of suction nozzles 261. The suction nozzle 261 is a holder capable of suctioning and holding the components. The suction nozzle 261 can be connected to any one of a negative pressure generator, a positive pressure generator, and the atmosphere via an electric switching valve. That is, the suction nozzle 261 can suction and hold the components by supplying negative pressure to the suction nozzle 261, and then the suction and holding of the components is released by supplying positive pressure thereto.

[0020] The component supply unit 23 is disposed in an end region in the X-axis direction of the mounting machine body 21. The component supply unit 23 has an upper frame 231, a lower frame 232, and a rear frame 233 for forming a plurality of supply support parts 24 that support the feeder 25 that supplies components in an insertable and removable manner. The upper frame 231 is a plate-like frame extending in the X-axis direction and the Y-axis direction. The upper frame 231 is disposed at one end of the mounting machine body 21 in the X-axis direction so that a region portion on one end side of the upper frame 231 in the X-axis direction is exposed to the outside from the mounting machine body 21 and a region portion on the other end side of the upper frame 231 in the X-axis direction is accommodated inside the mounting machine body 21. The lower frame 232 is a plate-like frame extending in the X-axis direction and the Y-axis direction, and is disposed on the lower side of the upper frame 231 in the Z-axis direction so as to face the upper frame 231. The lower frame 232 has a protruding part 2321 protruding upward in the Z-axis direction in a region portion on the other end side of the X-axis direction that is accommodated inside the mounting machine body 21. The rear frame 233 is a plate-shaped frame that extends in the Y-axis and Z-axis directions, and is positioned inside the mounting machine main body 21 closer to the center of the mounting machine main body 21 than the other ends of the upper frame 231 and the lower frame 232 in the X-axis direction.

[0021] Each of the multiple supply support parts 24 supports the feeder 25 in a removable manner in the component supply unit 23. In the component supply unit 23, the multiple supply support parts 24 are arranged side by side in the Y-axis direction. By inserting the feeder 25 into each of such supply support parts 24, the multiple feeders 25 are arranged side by side in the Y-axis direction.

[0022] The feeder 25 is a component supplying tool that supplies components. The component supplying method of the feeder 25 is not particularly limited as long as the feeder 25 is configured to be able to supply components. For example, a tape feeder that supplies components using a tape as a carrier, a tray feeder that supplies components by moving a tray on which the components are placed, or a stick feeder that supplies components stored in a cylindrical stick while pushing the components out of the stick may be used as the feeder 25. A bulk feeder to which a bulk cassette that stores bulk components formed by a collection of multiple components is detachably attached may also be used as the feeder 25.

[0023] The following describes a case where a tape feeder is used as the feeder 25. The feeder 25 supplies components by feeding a component storage tape PT capable of storing a plurality of components. The component storage tape PT is made up of a carrier tape PT1 having a plurality of storage sections for storing components, and a cover tape PT2 joined to the carrier tape PT1 so as to cover the storage sections. The feeder 25 includes a feeder main body 251, a reel support section 252, a tape feeding section 254, and a recovery section 255.

[0024] A tape-feeding path 253 is formed in the feeder body 251. The tape-feeding path 253 is a path along which the component storage tape PT is fed, and has a component removal section 2531 between the upstream end and downstream end in the feeding direction of the component storage tape PT. The reel support section 252 is disposed on the upstream end side of the tape-feeding path 253 in the feeder body 251. The reel support section 252 supports a reel around which the component storage tape PT is wound.

[0025] The tape feeding unit 254 is formed of, for example, a sprocket, and is disposed in the vicinity of the component removal unit 2531 of the tape feeding path 253. The tape feeding unit 254 feeds out the component storage tape PT from the reel supported by the reel support unit 252, and feeds out the component storage tape PT along the tape feeding path 253. The operation of the tape feeding unit 254 is controlled by a control circuit mounted on the control board 259. In the component storage tape PT fed along the tape feeding path 253, the cover tape PT2 is peeled off from the carrier tape PT1 upstream of the component removal unit 2531. This exposes the components on the carrier tape PT1 at the component removal unit 2531. The components exposed on the carrier tape PT1 can be removed by the head unit 26. That is, the head unit 26 removes the components supplied by the feeder 25 from the component removal unit 2531.

[0026] The cover tape PT2 peeled off from the carrier tape PT1 upstream of the component removal unit 2531 is collected by the collection unit 255. The collection unit 255 is composed of, for example, a pair of rollers that contact each other. In this case, the collection unit 255 collects the cover tape PT2 in accordance with the rotation of the pair of rollers. The cover tape PT2 collected by the collection unit 255 is stored in a collection box 2551.

[0027] The carrier tape PT1 after the components are removed by the head unit 26 is sent out from the feeder 25 via the downstream end of the tape-feeding path 253 by the feeding operation of the tape-feeding section 254. The carrier tape PT1 sent out from the feeder 25 is cut to a predetermined length by the tape cutter 23A arranged in the vicinity of the protruding portion 2321 of the lower frame 232 in the component supply unit 23.

[0028] As shown in FIG. 2, the feeder 25 has an upper positioning pin 256, a lower positioning pin 257, and a feeder side connector 258. The upper positioning pin 256 and the lower positioning pin 257 are pins provided so as to protrude from one end of the feeder body 251 in the X-axis direction. The upper positioning pin 256 and the lower positioning pin 257 are arranged at an interval from each other in the Z-axis direction at one end of the feeder body 251 in the X-axis direction, and the upper positioning pin 256 is located above the lower positioning pin 257. One end of the feeder body 251 in the X-axis direction has a stepped portion recessed toward the other side in the X-axis direction from the portion where the upper positioning pin 256 and the lower positioning pin 257 are provided. A feeder side connector 258 is provided at the stepped portion at one end of the feeder body 251 in the X-axis direction. The feeder side connector 258 is a connector electrically connected to a control board 259.

[0029] A plurality of supply support parts 24 for supporting the feeders 25 so as to be insertable and removable are formed on the upper frame 231, the lower frame 232, and the rear frame 233 of the component supply unit 23. Each supply support part 24 includes an upper holding rail 241, a lower holding rail 242, an upper pin insertion hole 243, a lower pin insertion hole 244, and a unit side connector 245.

[0030] A plurality of upper holding rails 241 are formed lined up in the Y-axis direction so as to extend in the X-axis direction on the lower surface of upper frame 231. Upper holding rails 241 are rail members that guide the upper ends of feeders 25 when feeders 25 move when inserted into or removed from supply support portion 24. A plurality of lower holding rails 242 are formed lined up in the Y-axis direction so as to extend in the X-axis direction on the upper surface of lower frame 232. Lower holding rails 242 are rail members that guide the lower ends of feeders 25 when feeders 25 move when inserted into or removed from supply support portion 24.

[0031] The upper pin insertion holes 243 are holes formed in a line in the Y-axis direction at the upper end of the rear frame 233. The upper pin insertion holes 243 allow the upper positioning pins 256 of the feeder 25 to pass through when the feeder 25 is inserted into the supply support part 24. On the other hand, when the feeder 25 is removed from the supply support part 24, the upper positioning pins 256 are released from being inserted into the upper pin insertion holes 243. The lower pin insertion holes 244 are holes formed in a line in the Y-axis direction at the lower end of the rear frame 233. The lower pin insertion holes 244 allow the lower positioning pins 257 of the feeder 25 to pass through when the feeder 25 is inserted into the supply support part 24. On the other hand, when the feeder 25 is removed from the supply support part 24, the lower positioning pins 257 are released from being inserted into the lower pin insertion holes 244. The feeder 25 is positioned with respect to the supply support portion 24 by inserting the upper positioning pin 256 into the upper pin insertion hole 243 and inserting the lower positioning pin 257 into the lower pin insertion hole 244 .

[0032] The unit side connectors 245 are provided in a line in the Y-axis direction on the protruding portion 2321 of the lower frame 232, and are electrically connected to a control portion of the component mounter 2B. The unit side connectors 245 are connected to the feeder side connectors 258 of the feeder 25 when the feeder 25 is inserted into the supply support portion 24.

[0033] When component mounter 2B produces component-mounted boards, multiple types of components are mounted on each board. Furthermore, different types of components are mounted on different types of boards. For this reason, multiple feeders 25 of different component types are arranged in the Y-axis direction in component supply unit 23 while being supported by supply supports 24. In this case, multiple feeders 25 are supported by each supply support 24 in component supply unit 23 so that the arrangement is optimized based on the mounting efficiency of components on the board by head unit 26. Specifically, the arrangement of multiple feeders 25 in component supply unit 23 is set so that the movement amount of head unit 26 is as small as possible when mounting components on the board.

[0034] [Detailed configuration of parts replacement system] As described above, in the component replacement system 3, the storage management device 4A and the replacement management device 5A receive the supply plan data D3 transmitted from the integrated management device 1A. The supply plan data D3 is data indicating a supply plan of the feeder 25 to the component supply unit 23 of the component mounter 2B. As shown in FIG. 1, the supply plan data D3 is data in which component type information D31, supply support part position information D32, and supply completion time information D33 are associated with each other. The component type information D31 is information indicating the type of components stored in a feeder 25 to be collected that is predicted to need to be collected due to a component shortage, among the multiple feeders 25 supported by each supply support part 24 of the component supply unit 23. The supply support part position information D32 is information indicating the position of a supply support part 24 of a collection source that supports the feeder 25 to be collected, among the multiple supply support parts 24 in the component supply unit 23. The supply completion time information D33 is information indicating a target time for completing the collection of the feeder 25 to be collected from the collection source supply support part 24 and for completing the supply of the feeder 25 to the collection source supply support part 24. The target time indicated by the supply completion time information D33 is set, for example, to one hour before a predicted time when the feeder 25 to be collected will run out of parts or the like.

[0035] As shown in FIG. 3, the storage management device 4A is connected to the storage device 4 so as to be able to communicate data with it. The storage device 4 is disposed at a position away from the component mounter 2B in the X-axis direction, and is a device that stores the feeders 25 for replenishing the component mounter 2B. The storage device 4 includes a storage device main body 41 and a storage unit 42. The storage device main body 41 is a housing having an internal space in which the storage unit 42 is disposed. The storage unit 42 has a plurality of storage support parts 421 disposed within the storage device main body 41. The plurality of storage support parts 421 are constituted by rails extending in the X-axis direction, and are arranged so as to be aligned in the Y-axis direction. The plurality of storage support parts 421 support a plurality of feeders 25 of different component types so as to be insertable and removable. In the storage unit 42, the feeders 25 are inserted into the respective storage support parts 421, so that the plurality of feeders 25 are arranged aligned in the Y-axis direction.

[0036] 3, seven storage support parts 421a-421g are arranged in order from one end to the other end in the Y-axis direction in the storage unit 42. An operator inserts the feeders 25 into each of the storage support parts 421a-421g in the storage unit 42. In the storage unit 42, of the seven storage support parts 421a-421g, five storage support parts 421a-421e respectively support feeders 25 of different component types, and storage support parts 421f, 421g in the specific area 422 on the other end side in the Y-axis direction are support parts that do not support feeders 25.

[0037] The storage management device 4A generates storage management data D4 shown in FIG. 3 based on the supply plan data D3 transmitted from the integrated management device 1A. The storage management data D4 is data for managing the storage status of the feeders 25 in the storage units 42 of the storage device 4. The storage management data D4 is data in which work completion time information D41 and storage array data D42 are associated with each other. The work completion time information D41 is information indicating a target time for a worker to complete the work of inserting the supply feeders 25 into each of the storage supports 421a to 421g of the storage unit 42. The target time indicated by the work completion time information D41 is set to, for example, one hour before the target time indicated by the supply completion time information D33 included in the supply plan data D3.

[0038] The storage arrangement data D42 is data indicating an arrangement of the supply feeders 25 supported and stored by each of the storage supports 421a to 421g in the storage unit 42. The storage arrangement data D42 is data in which component type information D421, feeder identification information D422, and storage support position information D423 are associated with each other. The component type information D421 is information indicating the type of component stored in the supply feeder 25. The component type indicated by the component type information D421 included in the storage arrangement data D42 matches the component type indicated by the component type information D31 included in the supply plan data D3. The feeder identification information D422 is information for identifying the supply feeders 25 supported by each of the storage supports 421a to 421g. The storage support position information D423 is information indicating the position in the storage unit 42 of the storage support parts 421a to 421g that support the supply feeders 25.

[0039] When the storage management device 4A generates the storage management data D4, the worker stores the components of the component type indicated by the component type information D421 and prepares the feeder 25 identified by the feeder identification information D422. Then, the worker performs an operation of inserting the prepared feeder 25 into the storage support section 421 at the position indicated by the storage support section position information D423 among the multiple storage supports 421a to 421g so as to arrive in time for the target time indicated by the work completion time information D41. The worker may also perform an operation of inserting the prepared feeder 25 into the storage support section 421 at any position in the storage unit 42. In this case, when the worker inserts the feeder 25 into each of the storage supports 421a to 421g, the storage support section position information D423 is registered in the storage arrangement data D42.

[0040] 3, in the storage unit 42, the storage support part 421a supports the feeder 25C, the storage support part 421b supports the feeder 25A, the storage support part 421c supports the feeder 25B, the storage support part 421d supports the feeder 25D, and the storage support part 421e supports the feeder 25E. And the storage support parts 421f and 421g in the specific area 422 on the other end side in the Y-axis direction in the storage unit 42 do not support the feeder 25.

[0041] In the part replacement system 3, the storage management device 4A may be incorporated in the storage device 4. That is, the storage device 4 may include a storage unit 42 arranged in a storage device main body 41, and the storage management device 4A.

[0042] As shown in FIG. 4, the replacement management device 5A is connected to the component replacement device 5 so as to be able to perform data communication. The component replacement device 5 is a working robot capable of moving within an area between the storage device 4 and the component mounter 2B. When the component replacement device 5 is disposed at a position facing the storage device 4, it performs an operation of extracting the feeder 25 for supply from each of the storage support parts 421a to 421g of the storage unit 42 and taking it inside. When the component replacement device 5 is disposed at a position facing the component mounter 2B, it performs an operation of extracting the feeder 25 from the supply support part 24 of the collection source that supports the feeder 25 to be collected in the component supply unit 23 and collecting it inside, and also performs an operation of inserting the feeder 25 to be supplied into the supply support part 24 of the collection source to supply it.

[0043] The part replacement device 5 includes a replacement device main body 51 and an operation unit 52. The replacement device main body 51 is a housing having an internal space in which the operation unit 52 is disposed. The operation unit 52 includes a moving table 53, an arm unit 54, and a hand unit 55. The operation unit 52 is a unit including a moving mechanism such as a ball screw mechanism for moving the moving table 53, the arm unit 54, and the hand unit 55, a driving motor serving as a driving source for the moving mechanism, and a control board for controlling the driving of the driving motor.

[0044] The movable base 53 has a plate-like shape extending in the X-axis direction and the Y-axis direction, and a plurality of exchange support parts 531 are provided on the upper surface thereof. The plurality of exchange support parts 531 are formed by rails extending in the X-axis direction, and are arranged on the movable base 53 so as to be aligned in the Y-axis direction. The plurality of exchange support parts 531 support the feeder 25 to be exchanged between the supply support part 24 of the component supply unit 23 and the storage support part 421 of the storage unit 42 so as to be insertable and removable. In the movable base 53, the feeder 25 is inserted into each exchange support part 531, so that the plurality of feeders 25 are aligned in the Y-axis direction. In the example shown in FIG. 4, six exchange support parts 531a to 531f are aligned in order from one end of the movable base 53 in the Y-axis direction to the other end. The movable base 53 is movable within a predetermined allowable movement range 532 in the Y-axis direction, which is the arrangement direction of the plurality of exchange support parts 531a to 531f, within the exchange device main body 51.

[0045] The arm unit 54 is movable in the space above the movable table 53 in the exchange device main body 51 in the Y-axis direction, which is the arrangement direction of the multiple exchange support parts 531a to 531f. The hand unit 55 is a gripping body that is movably attached to the arm unit 54 and can grip the feeder 25. The hand unit 55 is movable relative to the arm unit 54 in the X-axis direction along which the multiple exchange support parts 531a to 531f extend. The hand unit 55 moves in the Y-axis direction in the space above the movable table 53 in the exchange device main body 51 in conjunction with the movement of the arm unit 54, and also moves in the X-axis direction relative to the arm unit 54. The hand unit 55 moves in the X-axis direction relative to the arm unit 54 while gripping the feeder 25, thereby moving the feeder 25 so that the feeder 25 is inserted into or removed from each of the exchange support parts 531a to 531f on the movable table 53.

[0046] When the part replacement device 5 is disposed at a position facing the storage device 4 and the operating unit 52 is disposed facing the storage unit 42, the moving platform 53 moves in the Y-axis direction within a predetermined allowable movement range 532 so that the destination exchange support part 531, which is the destination of the feeder 25 to be transferred, faces the source storage support part 421 that supports the feeder 25 to be transferred from the storage unit 42 to the moving platform 53. The arm part 54 moves in the Y-axis direction so that the hand part 55 is positioned above the destination exchange support part 531. Then, the hand part 55 moves from the storage device 4 side to the part replacement device 5 side along the X-axis direction while holding the feeder 25 to be transferred. In this case, the feeder 25 to be transferred is removed from the source storage support part 421 in the storage unit 42 and moved to the destination exchange support part 531 on the moving platform 53 and inserted therein. By sequentially repeating the movements of the movable stage 53, the arm unit 54, and the hand unit 55, a plurality of feeders 25 to be supplied with different types of components are aligned in the Y-axis direction on the movable stage 53.

[0047] When the component replacement device 5 is disposed at a position facing the component mounter 2B and the operation unit 52 is disposed facing the component supply unit 23, the moving table 53 moves in the Y-axis direction within a predetermined allowable movement range 532 so that the exchange support part 531 at the destination of the feeder 25 to be collected faces the supply support part 24 at the source that supports the feeder 25 to be collected from the component supply unit 23 to the moving table 53. The arm part 54 moves in the Y-axis direction so that the hand part 55 is located above the exchange support part 531 at the destination. Then, the hand part 55 moves from the component mounter 2B side to the component replacement device 5 side along the X-axis direction while holding the feeder 25 to be collected. In this case, the feeder 25 to be collected is extracted from the supply support part 24 at the source in the component supply unit 23 and moved to and inserted into the exchange support part 531 at the destination on the moving table 53. As a result, the feeder 25 to be collected in the component supply unit 23 is collected on the moving table 53.

[0048] Further, the movable base 53 moves in the Y-axis direction within a predetermined allowable movement range 532 so that the exchange support part 531 of the supply source, which supports the feeder 25 to be supplied from the movable base 53 to the supply support part 24 of the collection source in the component supply unit 23, faces the supply support part 24 of the collection source. The arm part 54 moves in the Y-axis direction so that the hand part 55 is located above the exchange support part 531 of the supply source. Then, the hand part 55 moves from the component replacement device 5 side to the component mounter 2B side along the X-axis direction while holding the feeder 25 to be supplied. In this case, the feeder 25 to be supplied is extracted from the exchange support part 531 of the supply source on the movable base 53, and moved to and inserted into the supply support part 24 of the collection source in the component supply unit 23. As a result, the feeder 25 to be supplied on the movable base 53 is supplied into the component supply unit 23 so as to be replaced with the feeder 25 to be collected.

[0049] 4, the part replacement device 5 further includes a detection unit 56 and a notification unit 57. The detection unit 56 is a unit that detects the feeder 25 inserted into each of the replacement support parts 531a to 531f on the movable table 53 in response to the movement of the hand part 55. The detection unit 56 detects feeder identification information for identifying the feeder 25. The notification unit 57 is a unit that is attached to the outer surface of the replacement device main body 51 and notifies various types of information.

[0050] The replacement management device 5A is a device that manages the operation of the part replacement device 5. The replacement management device 5A includes a control unit 5A1 and a storage unit 5A2. The control unit 5A1 generates replacement management data D5 shown in Fig. 4 based on the supply plan data D3 transmitted from the integrated management device 1A. The replacement management data D5 generated by the control unit 5A1 is stored in the storage unit 5A2.

[0051] The replacement management data D5 is data for managing the operation of the operating unit 52 of the part replacement apparatus 5. The replacement management data D5 is data in which replacement completion time information D51, supply support part position information D52, and mobile table arrangement data D53 are associated with each other.

[0052] The replacement completion time information D51 is information indicating a target time for completing the operations of the operating unit 52, which are to arrange a plurality of feeders 25 to be supplied on the movable table 53, to retrieve feeders 25 to be retrieved from the component supply unit 23 onto the movable table 53, and to supply the feeders 25 to be supplied on the movable table 53 to the component supply unit 23. The target time indicated by the replacement completion time information D51 is set to a time falling within a predetermined allowable range centered on the target time indicated by the supply completion time information D33 included in the supply plan data D3.

[0053] The supply support part position information D52 is information that indicates the position of the supply support part 24, which is the recovery source and supports the feeder 25 to be recovered in the component supply unit 23. The position indicated by the supply support part position information D52 matches the position indicated by the supply support part position information D32 included in the supply plan data D3.

[0054] The movable table arrangement data D53 is data showing the arrangement of a plurality of types of feeders 25 to be supplied on the movable table 53. The movable table arrangement data D53 is data in which component type information D531, feeder identification information D532, and exchange support unit position information D533 are associated with each other. The component type information D531 is information showing the type of components contained in the feeder 25 to be supplied to the component supply unit 23 after being transferred onto the movable table 53, which is a feeder 25 to be transferred from the storage unit 42 to the movable table 53. The component type shown in the component type information D531 included in the movable table arrangement data D53 is consistent with the component type shown in the component type information D31 included in the supply plan data D3. The feeder identification information D532 is information for identifying the feeder 25 to be transferred from the storage unit 42 to the movable table 53, which is a feeder to be supplied to the component supply unit 23 after being transferred onto the movable table 53. The exchange support part position information D533 is information that indicates the position on the mobile table 53 of the exchange support part 531, which is the source of supply and supports the feeder 25 to be transferred from the storage unit 42 to the mobile table 53 and which is to be supplied to the component supply unit 23 after being transferred onto the mobile table 53.

[0055] The control unit 5A1 generates the movable carriage arrangement data D53 so that the arrangement of the feeders 25 to be replenished on the movable carriage 53 is optimized based on the efficiency of the exchange of the feeders 25 between the movable carriage 53 and the component supply unit 23, while taking into consideration that the target time indicated by the exchange completion time information D51 falls within an allowable range with respect to the time indicated by the supply completion time information D33. In this case, the arrangement of the feeders 25 to be replenished indicated by the movable carriage arrangement data D53 is an arrangement in which the target time indicated by the exchange completion time information D51 falls within an allowable range, and the amount of movement of the movable carriage 53 when the feeders 25 are exchanged between the movable carriage 53 and the component supply unit 23 falls within a predetermined target range and is as small as possible.

[0056] The control unit 5A1 generates the movable carriage arrangement data D53, for example, according to the following procedure. First, the control unit 5A1 confirms the arrangement of the feeders 25 in the storage unit 42 based on the storage management data D4, and also confirms the arrangement of the feeders 25 on the movable carriage 53 based on the detection result of the detection unit 56. The control unit 5A1 also confirms the component types and number of the feeders 25 to be collected in the component supply unit 23 based on the supply plan data D3. As a result, the control unit 5A1 identifies component type information D531 and feeder identification information D532 corresponding to the feeder 25 to be supplied.

[0057] Next, the control unit 5A1 checks the position of the supply support part 24 of the collection source that supports the feeder 25 to be collected in the component supply unit 23 based on the supply plan data D3. Then, the control unit 5A1 sets the supply order when the feeders 25 to be collected are replaced with the feeder 25 to be collected and replenished, so that the movement amount of the moving table 53 is within the target range and is as small as possible, while taking into consideration that the target time indicated by the exchange completion time information D51 falls within an allowable range for the time indicated by the supply completion time information D33. In this case, the supply order of the feeders 25 to be collected does not necessarily match the order of the earliest target time indicated by the supply completion time information D33. In other words, the supply order of the feeders 25 to be collected does not necessarily match the order of the earliest predicted time when the feeder 25 to be collected will run out of parts, etc.

[0058] For example, assume that the third feeder 25 is arranged between the first feeder 25 and the second feeder 25 in the component supply unit 23 in order of the earliest predicted time when a component shortage will occur. In this case, if the supply order of the feeders 25 to be supplied is set in order of the earliest predicted time when a component shortage will occur, when supplying to the second feeder 25 after supplying to the first feeder 25, the moving table 53 will pass the position of the third feeder 25 and move to the position of the second feeder 25. For this reason, the movement amount of the moving table 53 becomes large. Therefore, the control unit 5A1 sets the supply order of the feeders 25 to be supplied in the order of the first feeder 25, the third feeder 25, and the second feeder 25 so that the movement amount of the moving table 53 becomes small.

[0059] Next, the control unit 5A1 sets, for the multiple exchange support parts 531a-531f on the movable base 53, an exchange support part 531 as a recovery destination for recovering the feeder 25 to be recovered without supporting the feeder 25 to be replenished, and an exchange support part 531 as a supply source for supporting the feeder 25 to be replenished. At this time, the control unit 5A1 sets the positions of the exchange support parts 531 as the recovery destination and the supply source depending on whether the number of feeders 25 to be recovered is half or less of the number of exchange support parts 531a-531f on the movable base 53 or not.

[0060] When the number of feeders 25 to be collected exceeds half the number of exchange support parts 531a-531f on the movable base 53, as shown in the first example of Fig. 4, the control unit 5A1 sets the exchange support part 531a on the movable base 53 at the most one side in the Y axis direction as the support part to be collected, and sets the exchange support parts 531b-531f arranged on the other side in the Y axis direction with respect to the exchange support part 531a as the support parts of the supply source supporting the feeders 25A-25E to be replenished. At this time, the control unit 5A1 sets the positions of the exchange support parts 531b-531f of the supply source corresponding to each of the feeders 25A-25E to be replenished so that the feeders 25A-25E to be replenished are arranged in order of replenishment from one side to the other in the Y axis direction. As a result, the control unit 5A1 identifies exchange support part position information D533 indicating the position of the exchange support part 531a of the collection destination and the positions of the exchange support parts 531b to 531f of the supply source that support the feeders 25A to 25E to be supplied.

[0061] On the other hand, when the number of feeders 25 to be collected is less than half the number of exchange support parts 531a-531f on the movable base 53, as shown in the second example of Fig. 4, the control unit 5A1 sets the exchange support parts 531a, 531c, 531e of the collection destination and the exchange support parts 531b, 531d, 531f of the supply source supporting the feeders 25A-25C to be replenished to be alternately arranged in the Y-axis direction on the movable base 53. At this time, the control unit 5A1 sets the positions of the exchange support parts 531b, 531d, 531f of the supply source corresponding to each of the feeders 25A-25C to be replenished to be arranged in the order of replenishment from one side to the other in the Y-axis direction. As a result, the control unit 5A1 identifies exchange support part position information D533 indicating the positions of the exchange support parts 531a, 531c, and 531e of the collection destination and the positions of the exchange support parts 531b, 531d, and 531f of the supply source that support the feeders 25A to 25C to be supplied.

[0062] The control unit 5A1 can generate movable table arrangement data D53 indicating the arrangement of the feeders 25 to be replenished on the movable table 53 based on the component type information D531, feeder identification information D532, and exchange support part position information D533 identified as described above.

[0063] In the part replacement system 3, the replacement management device 5A including the control unit 5A1 may be incorporated in the part replacement device 5. That is, the part replacement device 5 may include an operation unit 52, a detection unit 56, a notification unit 57, and the replacement management device 5A, which are arranged in a replacement device main body 51.

[0064] [Control of the operating unit by the control unit] The control unit 5A1 controls the operation of the operating unit 52 of the part replacement device 5 based on the storage arrangement data D42 included in the storage management data D4 and the replacement management data D5 including the mobile table arrangement data D53. The control unit 5A1 moves the mobile table 53, the arm unit 54, and the hand unit 55 of the operating unit 52 by sending a control signal based on the storage arrangement data D42 and the replacement management data D5 to the control board of the operating unit 52.

[0065] (Array processing) When the part replacement device 5 is disposed at a position facing the storage device 4, and the operating unit 52 is disposed facing the storage unit 42, the control unit 5A1 performs an arrangement process in which the feeders 25 to be transferred in the storage unit 42 are moved onto the movable table 53, and the feeders 25 to be replenished are arranged on the movable table 53. This arrangement process will be described with reference to Figs. 5 to 9. The arrangement process shown in Figs. 5 to 9 is based on the movable table arrangement data D53 such that the arrangement of the feeders 25 to be replenished on the movable table 53 becomes the arrangement shown in the first example of Fig. 4.

[0066] The control unit 5A1 confirms the positions of the storage support parts 421a-421e of the transfer source that support the feeders 25A-25E of the transfer target in the storage unit 42, based on the storage arrangement data D42. The control unit 5A1 also confirms the positions of the exchange support parts 531b-531f of the transfer destination on the transfer table 53 corresponding to the feeders 25A-25E of the transfer target, based on the moving table arrangement data D53. Then, the control unit 5A1 moves the moving table 53, the arm part 54, and the hand part 55 so that the feeders 25A-25E of the transfer target supported by the storage support parts 421a-421e of the transfer source in the storage unit 42 move to the exchange support parts 531b-531f of the transfer destination on the moving table 53, and the arrangement of the feeders 25A-25E on the moving table 53 becomes the arrangement indicated by the moving table arrangement data D53.

[0067] At this time, the control unit 5A1 judges whether or not there is a feeder 25 to be processed in the specific feeder movement process shown in FIG. 5 among the feeders 25A-25E to be transferred in the storage unit 42. In the example of FIG. 5, the feeder 25C to be transferred supported by the storage support part 421a in the storage unit 42 is the feeder 25 to be processed in the specific feeder movement process. When the moving platform 53 is moved within the allowable movement range 532, if the exchange support part 531d of the transfer destination on the moving platform 53 does not face the storage support part 421a of the transfer source that supported the feeder 25C to be transferred in the storage unit 42, the control unit 5A1 performs the specific feeder movement process. In the specific feeder movement process, the control unit 5A1 moves the moving platform 53, the arm part 54, and the hand part 55 so that the feeder 25C to be transferred moves from the storage support part 421a of the transfer source to the storage support part 421f in the specific area 422 via the exchange support part 531a. When it is impossible to move the movable table 53 so that the destination exchange support section 531d faces the source storage support section 421a due to a restriction on the movement range of the movable table 53, the control unit 5A1 moves the feeder 25C to be transferred from the source storage support section 421a to the storage support section 421f in the specific area 422 via the exchange support section 531a.

[0068] Specifically, the control unit 5A1 moves the moving platform 53 in the Y-axis direction within the allowable movement range 532 so that the exchange support part 531a faces the storage support part 421a of the transfer source that supports the feeder 25C to be transferred. Next, the control unit 5A1 moves the arm part 54 in the Y-axis direction so that the hand part 55 is positioned above the exchange support part 531a. Then, the control unit 5A1 moves the hand part 55, while holding the feeder 25C to be transferred, from the storage device 4 side to the part exchange device 5 side along the X-axis direction. As a result, the feeder 25C to be transferred is removed from the storage support part 421a of the transfer source in the storage unit 42, and moved to and inserted into the exchange support part 531a on the moving platform 53.

[0069] Next, the control unit 5A1 moves the moving platform 53 in the Y-axis direction within the allowable movement range 532 so that the exchange support part 531a supporting the feeder 25C to be transferred faces the storage support part 421f in the specific area 422. Next, the control unit 5A1 moves the arm part 54 in the Y-axis direction so that the hand part 55 is positioned above the exchange support part 531a that has been moved to a position facing the storage support part 421f. Then, the control unit 5A1 moves the hand part 55 along the X-axis direction from the part exchange device 5 side to the storage device 4 side while holding the feeder 25C to be transferred. As a result, the feeder 25C to be transferred is removed from the exchange support part 531a on the moving platform 53 and moved to and inserted into the storage support part 421f in the specific area 422 of the storage unit 42.

[0070] When the specific feeder movement process is completed, the control unit 5A1 repeats the first arrangement movement process and the second arrangement movement process shown in FIGS. 6 to 8 until the arrangement of the feeders 25A to 25E on the moving stage 53 becomes the arrangement indicated by the moving stage arrangement data D53.

[0071] In the first arrangement movement process, the control unit 5A1 moves the moving platform 53 in the Y-axis direction within the allowable movement range 532 so that the exchange support part 531b of the transfer destination faces the storage support part 421b of the transfer source that supports the feeder 25A to be transferred. Next, in the second arrangement movement process, the control unit 5A1 moves the arm part 54 in the Y-axis direction so that the hand part 55 is positioned above the exchange support part 531b of the transfer destination. Then, the control unit 5A1 moves the hand part 55, while holding the feeder 25A to be transferred, from the storage device 4 side to the part replacement device 5 side along the X-axis direction. As a result, the feeder 25A to be transferred is removed from the storage support part 421b of the transfer source in the storage unit 42, and moved to and inserted into the exchange support part 531b of the transfer destination on the moving platform 53.

[0072] The control unit 5A1 also performs the first arrangement movement process and the second arrangement movement process on the feeder 25B to be transferred, in the same manner as in the case of the feeder 25A described above. As a result, the feeder 25B to be transferred is removed from the storage support part 421c of the transfer source in the storage unit 42, and moved to the exchange support part 531c of the transfer destination on the moving platform 53 and inserted therein.

[0073] The control unit 5A1 performs the first arrangement movement process and the second arrangement movement process described below for the feeder 25C to be transferred that has been moved to the storage support part 421f in the specific area 422 of the storage unit 42. In the first arrangement movement process, the control unit 5A1 moves the moving platform 53 in the Y-axis direction within the allowable movement range 532 so that the exchange support part 531d of the transfer destination faces the storage support part 421f in the specific area 422 that supports the feeder 25C to be transferred. Next, in the second arrangement movement process, the control unit 5A1 moves the arm part 54 in the Y-axis direction so that the hand part 55 is positioned above the exchange support part 531d of the transfer destination. Then, the control unit 5A1 moves the hand part 55 in the X-axis direction from the storage device 4 side to the part replacement device 5 side while holding the feeder 25C to be transferred. As a result, the feeder 25C to be transferred is removed from the storage support portion 421f in the specific area 422 of the storage unit 42, and moved to the transfer destination exchange support portion 531d on the moving platform 53 and inserted therein.

[0074] The control unit 5A1 also performs the first arrangement movement process and the second arrangement movement process on the feeders 25D and 25E to be transferred, in the same manner as in the case of the feeders 25A and 25B described above. As a result, the feeders 25D and 25E to be transferred are removed from the storage support parts 421d and 421e of the transfer source in the storage unit 42, and moved to the exchange support parts 531e and 531f of the transfer destination on the moving platform 53 and inserted therein.

[0075] By the first arrangement movement process and the second arrangement movement process of the control unit 5A1, the feeders 25A-25E to be transferred are removed from the storage support parts 421a-421e of the storage unit 42 as the transfer source, and moved to and inserted into the exchange support parts 531b-531f of the transfer destination on the transfer table 53. By repeatedly performing the first arrangement movement process and the second arrangement movement process by the control unit 5A1 for each of the multiple feeders 25A-25E to be transferred, the arrangement of the feeders 25A-25E on the transfer table 53 can be made into the arrangement indicated by the transfer table arrangement data D53.

[0076] As described above, in the arrangement process of moving the feeders 25 from the storage support section 421 of the storage unit 42 to the exchange support section 531 of the movable table 53 and arranging them on the movable table 53, the control unit 5A1 moves the movable table 53, the arm section 54, and the hand section 55 so that the arrangement of the feeders 25 on the movable table 53 becomes the arrangement indicated by the movable table arrangement data D53. The movable table arrangement data D53 is data indicating the arrangement of the feeders 25 on the movable table 53, which is set so that the movement amount of the movable table 53 when the feeders 25 are exchanged between the supply support section 24 of the component supply unit 23 and the exchange support section 531 of the movable table 53 falls within a target range and is as small as possible. Therefore, when the feeders 25 are exchanged between the component supply unit 23 and the movable table 53 in a state where a plurality of feeders 25 are arranged on the movable table 53 according to the movable table arrangement data D53, the movement amount of the movable table 53 can be kept within the target range. This makes it possible to improve the efficiency of exchange of the feeders 25 between the component supply unit 23 and the movable table 53.

[0077] 9, when the second array movement process of the control unit 5A1 is being performed, the detection unit 56 detects the feeder 25X transferred to the destination exchange support section 531f on the moving table 53. In this case, the control unit 5A1 judges whether the feeder 25X detected by the detection unit 56 matches the feeder 25E to be placed on the destination exchange support section 531f based on the moving table array data D53. If they do not match, the control unit 5A1 outputs an error command signal S1 to the notification unit 57 to command notification of error information SS1. The notification unit 57 can notify the error information SS1 based on the error command signal S1 output from the control unit 5A1.

[0078] When the control unit 5A1 outputs the error command signal S1, it moves the hand unit 55 so that the feeder 25X corresponding to the error command signal S1 moves from the exchange support unit 531f on the movable table 53 to the storage support unit 421e of the transfer source in the storage unit 42. In this case, the feeder 25X corresponding to the error command signal S1 is returned from the movable table 53 to the storage unit 42. This makes it possible to prevent the arrangement of the feeders 25 on the movable table 53 from becoming different from the movable table arrangement data D53.

[0079] Furthermore, when the control unit 5A1 outputs the error command signal S1, the control unit 5A1 excludes the feeder 25X corresponding to the error command signal S1 from the processing target of the exchange process described below in which the feeder 25 is exchanged between the component supply unit 23 and the moving table 53. Specifically, the control unit 5A1 deletes the component type information D531 and the feeder identification information D532 related to the feeder 25X corresponding to the error command signal S1 in the exchange management data D5. In this case, the feeder 25X corresponding to the error command signal S1 is excluded from the processing target of the exchange process in which the feeder 25 is exchanged between the component supply unit 23 and the moving table 53. This makes it possible to prevent the feeder 25X corresponding to the error command signal S1 from being supplied to the component supply unit 23.

[0080] In addition, when the control unit 5A1 outputs the error command signal S1, it outputs an alternative preparation request signal S2 requesting the preparation of a feeder 25E to replace the feeder 25X corresponding to the error command signal S1. The alternative preparation request signal S2 output from the control unit 5A1 is input to the integrated management device 1A. In response to the input of the alternative preparation request signal S2, the integrated management device 1A updates the supply plan data D3 and transmits an alternative preparation command signal S3 to the storage management device 4A. The alternative preparation command signal S3 is a signal that commands the preparation of an alternative feeder 25E indicated by the alternative preparation request signal S2. When the storage management device 4A receives the alternative preparation command signal S3, it notifies, for example, information indicating that the preparation of an alternative feeder 25E is necessary. This allows, for example, an operator to prepare a feeder 25E to replace the feeder 25X corresponding to the error command signal S1 and replenish the prepared feeder 25E in the storage unit 42.

[0081] The control unit 5A1 does not have to output the replacement preparation request signal S2. In this case, for example, the worker can prepare a feeder 25E to replace the feeder 25X corresponding to the error command signal S1 based on the error information SS1 notified by the notification unit 57, and replenish the storage unit 42 with the prepared feeder 25E.

[0082] (Exchange process) When the component replacement device 5 is disposed at a position facing the component mounter 2B, and the operation unit 52 is disposed facing the component supply unit 23, the control unit 5A1 performs replacement processing. In the replacement processing, the control unit 5A1 moves the movable stage 53, the arm unit 54, and the hand unit 55 so that the feeder 25 moves and is replaced between the component supply unit 23 and the movable stage 53 based on the replacement management data D5. In the replacement processing, the control unit 5A1 moves the movable stage 53, the arm unit 54, and the hand unit 55 so that the feeder 25 is replaced between the component supply unit 23 and the movable stage 53 according to the order of arrangement of the feeders 25 to be supplied on the movable stage 53, that is, the supply order, which is indicated by the movable stage arrangement data D53 included in the replacement management data D5. This replacement processing will be described with reference to FIG. 10 and FIG. 11. In FIG. 10 and FIG. 11, the feeder 25A to be collected from the component supply unit 23 to the movable stage 53 is indicated by hatching.

[0083] Based on the supply support part position information D52 included in the replacement management data D5, the control unit 5A1 checks the position of the recovery source supply support part 24b that supports the feeder 25A to be recovered in the component supply unit 23. Also, based on the movable carriage arrangement data D53, the control unit 5A1 checks the position of the replacement support part 531b of the supply source on the movable carriage 53 of the feeder 25A to be replenished in response to the recovery of the feeder 25A to be recovered. In the replacement process, the control unit 5A1 repeatedly performs the recovery process shown in Fig. 10 and the supply process shown in Fig. 11.

[0084] In the collection process, the control unit 5A1 performs a first collection movement process and a second collection movement process. In the first collection movement process, the control unit 5A1 moves the moving table 53 in the Y-axis direction within the range of the allowable movement range 532 so that the exchange support part 531a of the collection destination faces the supply support part 24b of the collection source that supports the feeder 25A to be collected. Next, in the second collection movement process, the control unit 5A1 moves the arm part 54 in the Y-axis direction so that the hand part 55 is positioned above the exchange support part 531a of the collection destination. Then, the control unit 5A1 moves the hand part 55 in the X-axis direction from the component mounter 2B side to the component replacement device 5 side while holding the feeder 25A to be collected. As a result, the feeder 25A to be collected is extracted from the supply support part 24b of the collection source in the component supply unit 23 and moved to the exchange support part 531a of the collection destination on the moving table 53 for collection.

[0085] In the supply process, the control unit 5A1 performs a first supply movement process and a second supply movement process. In the first supply movement process, the control unit 5A1 moves the moving table 53 in the Y-axis direction within the range of the allowable movement range 532 so that the exchange support part 531b of the supply source supporting the feeder 25A to be supplied faces the supply support part 24b of the recovery source to be the supply destination. Next, in the second supply movement process, the control unit 5A1 moves the arm part 54 in the Y-axis direction so that the hand part 55 is located above the exchange support part 531b of the supply source. Then, the control unit 5A1 moves the hand part 55 in the X-axis direction while holding the feeder 25A to be supplied from the component replacement device 5 side to the component mounter 2B side. As a result, the feeder 25A to be supplied is removed from the exchange support part 531b of the supply source on the moving table 53 and moved to the supply support part 24b of the recovery source in the component supply unit 23 for supply.

[0086] In the component mounting system 1, the component replacement system 3 increases the efficiency of replacement of the feeders 25 between the component supply unit 23 and the movable table 53. In this case, the feeders 25A to be collected due to a shortage of components or the like are efficiently collected from the component supply unit 23, and the feeders 25A to be replenished are efficiently replenished to the component supply unit 23 in response to the collection.

[0087] The above-mentioned specific embodiment mainly includes the invention having the following configuration.

[0088] A component replacement system according to one aspect of the present invention is a system for replenishing a component supplying tool to a component supplying unit in response to retrieval of the component supplying tool from the component supplying unit in which a plurality of supply support parts for supporting and storing the component supplying tools for supplying components to be mounted on a board are arranged in a predetermined direction. The component replacement system includes a storage unit in which a plurality of storage support parts for supporting and storing a plurality of the component supplying tools of different component types are arranged in a predetermined direction, an operation unit including a moving platform in which a plurality of exchange support parts for supporting the component supplying tools to be exchanged between the supply support parts and between the storage support parts are arranged in a predetermined direction and which is movable in the arrangement direction of the plurality of exchange support parts, a gripper for gripping the component supplying tool and moving relative to the moving platform to move the component supplying tool, and a control unit for controlling the operation unit. When the operation unit is arranged opposite to the component supplying unit, the control unit performs an exchange process for moving the moving platform and the gripper so that the component supplying tool is moved and exchanged between the plurality of supply support parts and the plurality of exchange support parts. In addition, when the operating unit is positioned opposite the storage unit, the control unit performs an arrangement process, as a pre-processing step of the replacement process, in which the multiple types of part supply tools supported on the multiple storage support parts are moved to the multiple replacement support parts, and the arrangement of the multiple types of part supply tools on the mobile table is arranged as indicated by predetermined arrangement data to keep the movement amount of the mobile table in the replacement process within a target range.

[0089] According to the above-mentioned component replacement system, in an arrangement process in which the component supply tools are moved from the storage support part of the storage unit to the exchange support part of the mobile table and arranged on the mobile table, the control unit moves the mobile table and the gripper so that the arrangement of the component supply tools on the mobile table becomes the arrangement indicated by the arrangement data. The arrangement data is data indicating the arrangement of the component supply tools on the mobile table, which is set so that the movement amount of the mobile table in the exchange process in which the component supply tools are exchanged between the supply support part of the component supply unit and the exchange support part of the mobile table falls within a target range. Therefore, when the component supply tools are exchanged between the component supply unit and the mobile table in a state in which a plurality of component supply tools are arranged on the mobile table according to the arrangement data, the movement amount of the mobile table can be kept within the target range. This makes it possible to increase the exchange efficiency of the exchange of the component supply tools between the component supply unit and the mobile table.

[0090] In the above-mentioned part replacement system, in the arrangement process, the control unit may perform a first movement process of moving the mobile table so that a destination support part, among the multiple exchange support parts, to which the part supply tool to be transferred will be transferred faces a source support part, among the multiple storage support parts, that supports the part supply tool to be transferred from the storage unit to the mobile table, and a second movement process of moving the gripper so that the part supply tool to be transferred moves from the source support part to the destination support part after the first movement process.

[0091] In this aspect, the component supply tool to be transferred is removed from the storage support part of the storage unit as the transfer source and moved to the exchange support part on the transfer platform as the transfer destination by the first movement process and the second movement process of the control unit, and is inserted. The first movement process and the second movement process by the control unit are repeatedly performed corresponding to each of the multiple component supply tools to be transferred, so that the arrangement of the component supply tools on the transfer platform can be made into the arrangement indicated by the arrangement data.

[0092] In the above-mentioned part replacement system, in the storage unit, among the plurality of storage support parts, a support part within a specific area is a support part that does not support the part supply tool, and the moving platform is movable within a predetermined allowable movement range in the arrangement direction of the plurality of replacement support parts. Then, when the destination support part does not face the source support part when the moving platform is moved within the allowable movement range, the control unit moves the moving platform and the gripper so that the part supply tool to be transferred moves from the source support part to the support part within the specific area via the replacement support part.

[0093] In this embodiment, when it is impossible to move the mobile table so that the destination exchange support part faces the source storage support part due to a restriction placed on the movement range of the mobile table, the component supply tool to be transferred is moved from the source storage support part to the storage support part within a specific area via the exchange support part.

[0094] In the above-mentioned part replacement system, when the part supply tool to be transferred is moved to a support part within the specific area, the control unit may, in the first movement process, move the moving table so that the destination support part faces the support part within the specific area, and, in the second movement process, move the gripper so that the part supply tool to be transferred supported by the support part within the specific area is moved to the destination support part.

[0095] In this aspect, the part supply tool to be transferred, which has been moved to the storage support section within a specific area of ​​the storage unit, is extracted from the storage support section within the specific area by the first movement process and the second movement process of the control unit, and moved to the exchange support section on the moving table to which it is to be transferred, and inserted.

[0096] The above-mentioned part replacement system may further include a detection unit that detects the part supply tool to be transferred that has been transferred to the destination support part in the second movement process, and an alarm unit that notifies various information. In this case, the control unit determines whether the part supply tool detected by the detection unit matches the part supply tool to be placed on the destination support part based on the arrangement data, and outputs an error command signal to the alarm unit to command the alarm unit to notify error information if they do not match.

[0097] In this aspect, when the part supply tool transferred to the destination exchange support part on the moving table does not match the part supply tool that should be placed on the destination support part based on the arrangement data, the alarm unit can alarm error information based on the error command signal output from the control unit.

[0098] In the above-mentioned part replacement system, the control unit may move the gripper so that the part supply tool to be transferred corresponding to the error command signal moves from the destination support part to the source support part.

[0099] In this embodiment, the component supply tool corresponding to the error command signal is returned from the movable table to the storage unit, thereby preventing the arrangement of the component supply tools on the movable table from becoming different from the arrangement data.

[0100] In the above-mentioned part replacement system, the control unit may exclude the part supply tool to be transferred that corresponds to the error command signal from the part supply tool to be processed in the replacement process.

[0101] In this embodiment, the component supply tool corresponding to the error command signal is excluded from the processing target of the exchange process in which the component supply tool is exchanged between the component supply unit and the moving table, thereby making it possible to prevent the component supply tool corresponding to the error command signal from being supplied to the component supply unit.

[0102] In the above-mentioned part replacement system, the control unit may output an alternative preparation request signal for requesting preparation of a part supply tool to replace the part supply tool to be transferred corresponding to the error command signal.

[0103] In this embodiment, the control unit outputs a replacement preparation request signal, whereby, for example, an operator can prepare a component supply tool to replace the component supply tool corresponding to the error command signal and replenish the storage unit with the prepared component supply tool.

[0104] A component mounting system according to another aspect of the present invention includes a component supply unit having a plurality of supply support parts arranged in a predetermined direction supporting component supply tools that supply components, a head unit that mounts components supplied by the component supply tools supported by the supply support parts onto a substrate, and the above-described component replacement system that replenishes the component supply tools to the component supply unit in response to recovering the component supply tools from the component supply unit.

[0105] According to this component mounting system, the component replacement system improves the efficiency of replacement of component supply tools between the component supply unit and the moving table. In this case, a component supply tool to be collected due to a shortage of components or the like is efficiently collected from the component supply unit, and a component supply tool to be replenished is efficiently replenished to the component supply unit in response to the collection.

[0106] As described above, according to the present invention, it is possible to provide a component replacement system capable of increasing the efficiency of replacement of component supply tools in a component supply unit, and a component mounting system including the same.
