[0004] [Patent Document 1] Japanese Patent Application Publication No. 2017-216379 Summary of the Invention [Problem to be solved by the invention]

[0005] The self-propelled part supply device disclosed in Patent Document 1 does not take into consideration the arrangement of the storage containers in the storage container storage unit, which can make it difficult to accurately retrieve storage containers from the storage container holding device to the storage container storage unit and replenish storage containers from the storage container storage unit to the storage container holding device.

[0006] An object of the present invention is to provide a component replacement system that can accurately collect and replenish component supply members for a plurality of component supply units, and a component mounting system equipped with the same. [Means for solving the problem]

[0007] According to one aspect of the present invention, a component replacement system supplies supply components to be replenished in response to the recovery of recovered components as component supply components to be recovered from a plurality of component supply units each having an arrangement of a plurality of mounting portions capable of mounting the component supply components that supply components to be mounted on a circuit board. The component replacement system includes a replacement device having a support unit having an arrangement of a plurality of supports capable of supporting the recovered components and the supply components, and an operation unit that performs a series of replacement operations to recover the recovered components and replenish the supply components between the plurality of component supply units and the support unit, and a replacement management device that performs, as processes for managing the operation of the replacement device, a management data generation process that generates support arrangement data indicating the arrangement of the recovered components and the supply components in the support unit, and a replacement process that causes the operation unit to perform the replacement operation based on the support arrangement data. In the management data generation process, the replacement management device performs a selection process to select multiple recovery components to be recovered from the part supply components attached to each of the attachment portions of the multiple part supply units, an extraction process to extract a predetermined number of the recovery components from the multiple recovery components selected in the selection process as extracted recovery components, and a setting process to set the positions of the recovery support components that support the extracted recovery components and the supply support components that support the supply components corresponding to the extracted recovery components, within the workable range in which the replacement work can be performed by the work unit, using the support component that is positioned opposite the attachment portion on the multiple part supply units to which the extracted recovery components are attached as a reference position, at the multiple support components of the support unit, and record the setting results in the support arrangement data, and repeats the extraction process and the setting process until a predetermined termination condition is met.

[0008] In this part replacement system, the replacement management device performs a management data generation process to generate support arrangement data indicating the arrangement of recovered parts and supply parts in the support unit of the replacement device, and a replacement process to cause the operating unit of the replacement device to perform replacement work based on the support arrangement data. In the management data generation process, the replacement management device selects multiple recovered parts to be recovered from the component supply parts attached to the respective attachment portions of the multiple component supply units, and extracts a predetermined number of extracted and recovered parts from the multiple recovered parts. The replacement management device then sets the positions of the recovery support parts that support the extracted and recovered parts and the supply support parts that support the supply parts corresponding to the extracted and recovered parts, on the multiple support portions of the support unit, and records the setting results in the support arrangement data.

[0009] The positions of the recovery support portion and the supply support portion on the support unit recorded in the support arrangement data are set within an operable range in which the replacement operation by the working unit can be performed, with the support portion at a position facing the mounting portion on the component supply unit to which the extraction and recovery member is attached set as the reference position. In this case, when the working unit performs the replacement operation based on the support arrangement data through the replacement process after the management data generation process by the replacement management device, it is possible to accurately recover the recovery member from the recovery source mounting portion of the component supply unit facing the support portion at the reference position of the support unit to the recovery support portion of the support unit, and it is also possible to accurately supply the supply member from the supply support portion of the support unit to the recovery source mounting portion as a supply destination.

[0010] In the above-described part replacement system, the support unit may be movable within a predetermined movement range in the arrangement direction of the plurality of support parts relative to each of the plurality of part supply units. In this case, the replacement management device, in the setting process, sets the positions of the recovery support part and the replenishment support part within a range in which the movement range is set as the workable range relative to the reference position for the plurality of support parts of the support unit.

[0011] In this aspect, the positions of the recovery support portion and the supply support portion on the support unit are set within the movement range of the support unit relative to the reference position. In this case, when the working unit performs replacement work based on the support arrangement data, when the recovery support portion faces the recovery source mounting portion of the component supply unit due to movement within the movement range of the support unit, it is possible to accurately recover the recovery member from the recovery source mounting portion to the recovery support portion. On the other hand, when the support unit moves within the movement range so that the supply support portion faces the recovery source mounting portion of the component supply unit, it is possible to accurately supply the supply member from the supply support portion to the recovery source mounting portion as a supply destination.

[0012] In the above-mentioned part replacement system, the replacement management device may, in the setting process, set the positions of the recovery support section and the supply support section for the multiple support sections of the support unit, giving priority to positions close to the center position in the arrangement direction within a range in which the movement range relative to the reference position is the workable range.

[0013] In this embodiment, the positions of the recovery support portion and the supply support portion on the support unit are set to positions close to the center of the arrangement direction within the movement range of the support unit with respect to the reference position. In this case, even if the reference positions facing the attachment portions of the recovery sources on the support unit are biased toward the end positions in the arrangement direction due to uneven positions of the attachment portions of the recovery sources to which the recovery members are attached in the multiple component supply units, the positions of the recovery support portion and the supply support portion on the support unit can be set to target a relatively large number of recovery members attached to the attachment portions of the recovery sources.

[0014] In the above-mentioned part replacement system, the replacement management device may, in the setting process, set the positions of the recovery support section and the supply support section for the multiple support sections of the support unit, giving priority to positions closest to the reference position within a range in which the movement range relative to the reference position is the workable range.

[0015] In this aspect, the positions of the recovery support section and the supply support section on the support unit are set with priority given to positions closest to the reference position within the movement range of the support unit relative to the reference position. In this case, when the working unit performs replacement work based on the support array data, the amount of movement within the movement range of the support unit can be made as small as possible. This makes it possible to improve the efficiency of the replacement work.

[0016] In the above-mentioned part replacement system, the replacement management device may, in the extraction process, sort the multiple recovered parts selected in the selection process in order of recovery priority, and extract a predetermined number of the recovered parts with the highest priority as the extracted recovered parts.

[0017] In this aspect, in the setting process after the extraction process by the replacement management device, the positions of the collection support section and the supply support section in the support unit can be set by giving priority to the collection member with the highest collection priority.

[0018] In the above-described part replacement system, the replacement device may be movable along a movement path that passes through each of the plurality of part supply units. In this case, in the setting process, the replacement management device recognizes the work order of the replacement work to be performed by the work unit corresponding to a predetermined number of the extraction and recovery members according to the order in which the replacement device moving along the movement path arrives at each of the plurality of part supply units, and sets the positions of the recovery support unit and the supply support unit in the work order of the extraction and recovery members.

[0019] In this aspect, in the setting process by the replacement management device, the positions of the recovery support section and the supply support section in the support unit can be set in the order of replacement work performed by the work unit, taking into account that the replacement device moves along a movement path.

[0020] In the above-mentioned parts replacement system, when the replacement management device repeatedly performs each of the extraction process and the setting process, it may use a predetermined allowable processing time as the termination condition, and terminate the repetition of each of the processes when the allowable processing time has elapsed, thereby terminating the management data generation process and outputting the support array data at that time.

[0021] In this aspect, the replacement management device repeatedly performs the extraction process and the setting process in the management data generation process until the allowable processing time has elapsed. In this case, in the replacement process after the management data generation process, the replacement management device can cause the working unit to perform the replacement work based on the support arrangement data in which the setting results of each position of the recovery support part and the supply support part of the support unit set in the setting process until the allowable processing time has elapsed.

[0022] In the above-mentioned parts replacement system, when the replacement management device repeatedly performs each of the extraction process and the setting process, it may use a predetermined allowable load weight of the support unit as the termination condition, and terminate the repetition of each process when the expected load weight when the recovery member is supported on the recovery support section and the supply member is supported on the supply support section set in the setting process reaches the allowable load weight, thereby terminating the management data generation process and outputting the support arrangement data at that time.

[0023] In this aspect, the replacement management device repeatedly performs the extraction process and the setting process in the management data generation process until the expected load weight when it is assumed that the recovery member and the supply member are supported by the support unit reaches the allowable load weight. In this case, in the replacement process after the management data generation process, the replacement management device can cause the working unit to perform the replacement work based on the support arrangement data that records the setting results of each position of the recovery support part and the supply support part of the support unit that were set in the setting process until the expected load weight reaches the allowable load weight.

[0024] In the above-mentioned parts replacement system, when the replacement management device repeatedly performs each of the extraction process and the setting process, it may terminate the management data generation process by ending the repetition of each process when the setting of each position of the recovery support unit and the supply support unit in the setting process is completed for all of the multiple recovery members selected in the selection process, and output the support arrangement data at that time.

[0025] In this aspect, the replacement management device terminates the repetition of the extraction process and the setting process in the management data generation process when the setting of the positions of the recovery support section and the supply support section in the support unit is completed for all of the multiple recovery members selected in the selection process.

[0026] In the above-mentioned part replacement system, the replacement management device may perform a confirmation process after the management data generation process is completed and before performing the replacement process, to confirm the total work time required for the work unit to complete all of the replacement work based on the support arrangement data.

[0027] In this aspect, before performing the replacement process, the replacement management device can confirm the total work time required for the work unit to complete all replacement work based on the support arrangement data generated in the management data generation process.

[0028] A component mounting system according to another aspect of the present invention includes a plurality of component supply units each having an array of a plurality of mounting sections capable of mounting component supply members that supply components to be mounted on a board, and the above-described component replacement system that replenishes supply members to be replenished in response to recovering recovery members as the component supply members to be recovered from the plurality of component supply units. [Effects of the Invention]

[0029] As described above, according to the present invention, it is possible to provide a component replacement system that can accurately collect and replenish component supply members for multiple component supply units, and a component mounting system equipped with the same.

DETAILED DESCRIPTION OF THE INVENTION

[0031] 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.

[0032] [Overall configuration of component mounting system] 1 is a diagram schematically illustrating the configuration of a component mounting system 100 to which a component replacement system 6S according to an embodiment of the present invention is applied. The component mounting system 100 is a system that produces mounted boards on which components such as electronic components are mounted on a board such as a printed circuit board. The component mounting system 100 includes a production system 1S and a component replacement system 6S.

[0033] The production system 1S includes a production line 1L that produces mounted boards and a production management device 1M. The production line 1L includes at least a plurality of mounting machines 2 arranged in the board transport direction. The production line 1L can produce mounted boards by mounting components on boards using the plurality of mounting machines 2. FIG. 1 shows the production line 1L arranged with four mounting machines 2: a first mounting machine 2A, a second mounting machine 2B, a third mounting machine 2C, and a fourth mounting machine 2D. Note that the production line 1L may include a printer 1 that prints solder paste on the boards, located upstream of the plurality of mounting machines 2 in the board transport direction, and a reflow furnace 4 that performs reflow processing, located downstream of the plurality of mounting machines 2 in the transport direction. In addition, a first inspection machine 3 that inspects the mounted board before the reflow process may be placed at a position between the mounting machine 2 and the reflow furnace 4 in the conveying direction of the board, and a second inspection machine 5 that inspects the mounted board after the reflow process may be placed at a position downstream of the reflow furnace 4.

[0034] The production management device 1M is connected to each of the plurality of mounting machines 2 so as to be able to perform data communication with the respective mounting machines 2. The production management device 1M is configured by, for example, a personal computer, and manages the plurality of mounting machines 2.

[0035] The part replacement system 6S includes at least one replacement device 7, a replacement management device 7M, at least one storage device 8, and a storage management device 8M. In the part replacement system 6S, the replacement device 7 and the replacement management device 7M are connected to enable data communication, and the storage device 8 and the storage management device 8M are connected to enable data communication. The replacement management device 7M and the storage management device 8M are configured, for example, by personal computers. The replacement management device 7M manages the replacement device 7. The storage management device 8M manages the storage device 8.

[0036] The component mounting system 100 also includes an integrated management device UM connected to each of the production management device 1M, the exchange management device 7M, and the storage management device 8M so as to be capable of data communication. The integrated management device UM is configured by, for example, a personal computer.

[0037] In the component mounting system 100, production plan data D1 is transmitted from the integrated management device UM to the production management device 1M. When the production management device 1M receives the production plan data D1, the multiple mounting machines 2 produce mounted boards in accordance with the production plan data D1. The production management device 1M manages the production of mounted boards by the multiple mounting machines 2. The production management device 1M transmits production status data D2 indicating the status of production of mounted boards by the multiple mounting machines 2 to the integrated management device UM.

[0038] Based on the production status data D2 transmitted from the production management device 1M, the integrated management device UM recognizes the predicted time of component shortages and the types of components that have run out associated with the production of mounted boards by the multiple mounting machines 2. Then, based on the recognition results, the integrated management device UM generates component replacement plan data D3 that indicates a replacement plan for component supply members to be replenished in response to the collection of component supply members for the multiple mounting machines 2. The integrated management device UM transmits the generated component replacement plan data D3 to each of the replacement management device 7M and the storage management device 8M.

[0039] When the storage management device 8M receives the part replacement plan data D3, the worker or work robot prepares supply materials indicating the part supply materials to be supplied to the multiple mounting machines 2 based on the part replacement plan data D3. The worker or work robot replenishes the prepared supply materials in the storage device 8. The storage device 8 stores multiple supply materials of different component types in a state where they are arranged in a predetermined direction in the storage unit 81. The storage management device 8M manages the storage status of the supply materials in the storage unit 81 of the storage device 8.

[0040] When the replacement management device 7M receives the part replacement plan data D3, the replacement device 7 takes in supply parts from the storage device 8 and performs a series of replacement operations to supply supply parts to the multiple mounting machines 2 in response to the collection of collection parts indicating the part supply parts to be collected. The replacement management device 7M manages the operation of the replacement device 7.

[0041] [Detailed configuration of the production system] As described above, in the production system 1S, when the production management device 1M receives production plan data D1 transmitted from the integrated management device UM, the multiple mounting machines 2 produce mounted boards in accordance with the production plan data D1. This mounting machine 2 will be described with reference to FIG. 2. Note that, below, directional relationships will be described using XYZ orthogonal coordinate axes. The X-axis and Y-axis directions are orthogonal to each other on a horizontal plane, and the Z-axis direction is a direction extending vertically and orthogonal to both the X-axis and Y-axis directions.

[0042] The plurality of mounting machines 2 are devices that mount components on a board to produce a mounted board. Each of the plurality of mounting machines 2 includes a mounting machine main body 21, a transport conveyor 22, a component supply unit 23, and a head unit 26.

[0043] The mounter main body 21 is a housing having an internal space in which the components of the mounter 2 are arranged. The transport conveyor 22 extends in the Y-axis direction and is arranged in an approximately central region inside the mounter main body 21. The transport conveyor 22 transports boards in the Y-axis direction. The head unit 26 mounts components on the boards transported by the transport conveyor 22. The head unit 26 retrieves components from feeders 25 arranged in the component supply unit 23 and mounts the retrieved components on the boards. The head unit 26 is equipped with multiple suction nozzles 261. The suction nozzles 261 are holders capable of suctioning and holding components. The suction nozzles 261 can be connected to a negative pressure generator, a positive pressure generator, or the atmosphere via an electric switching valve. In other words, supplying negative pressure to the suction nozzles 261 enables the suction nozzles 261 to suction and hold components, and then supplying positive pressure releases the suction and holding of the components.

[0044] The component supply unit 23 is disposed in an end region of the mounter main body 21 in the X-axis direction. The component supply unit 23 has an upper frame 231, a lower frame 232, and a rear frame 233 for forming a plurality of mounting sections 24 to which feeders 25 for supplying components can be attached. The upper frame 231 is a plate-like frame extending in the X-axis and Y-axis directions. The upper frame 231 is disposed at one end of the mounter main body 21 in the X-axis direction so that a region on one end side of the upper frame 231 in the X-axis direction is exposed to the outside from the mounter main body 21 and a region on the other end side of the upper frame 231 in the X-axis direction is housed inside the mounter main body 21. The lower frame 232 is a plate-like frame extending in the X-axis and Y-axis directions and is disposed below the upper frame 231 in the Z-axis direction so as to face the upper frame 231. The lower frame 232 has a protrusion 2321 that protrudes upward in the Z-axis direction in a region on the other end side of the lower frame 232 in the X-axis direction that is housed inside the mounter main 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.

[0045] A feeder 25 is detachably attached to each of the multiple mounting sections 24 in the component supply unit 23. In the component supply unit 23, the multiple mounting sections 24 are arranged side by side in the Y-axis direction. By inserting a feeder 25 into each of such mounting sections 24, the multiple feeders 25 are arranged side by side in the Y-axis direction.

[0046] Feeder 25 is a component supply member that supplies components. There are no particular limitations on the component supply method of feeder 25, as long as it is configured to be able to supply components. For example, feeder 25 can be 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 by pushing them out of the stick.

[0047] The following describes a case where a tape feeder is used as feeder 25. Feeder 25 supplies components by feeding out component storage tape PT, which can store multiple components. Component storage tape PT consists of carrier tape PT1, which has multiple storage compartments for storing components, and cover tape PT2, which is joined to carrier tape PT1 so as to cover the storage compartments. Feeder 25 includes a feeder main body 251, a reel support section 252, a tape feeding section 254, and a recovery section 255.

[0048] 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 of the component storage tape PT in the feeding direction. 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.

[0049] The tape feeding unit 254 is formed of, for example, a sprocket, and is arranged near the component take-out unit 2531 of the tape feed 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 the component storage tape PT along the tape feed 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 feed path 253, the cover tape PT2 is peeled off from the carrier tape PT1 upstream of the component take-out unit 2531. This exposes the components on the carrier tape PT1 in the component take-out unit 2531. The components exposed on the carrier tape PT1 can be taken out by the head unit 26. That is, the head unit 26 takes out the components supplied by the feeder 25 from the component take-out unit 2531.

[0050] 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 configured, for example, with a pair of rollers that abut against 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.

[0051] After the components are taken out by the head unit 26, the carrier tape PT1 is fed outward 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 fed outward from the feeder 25 is cut to a predetermined length by the tape cutter 23A arranged near the protrusion 2321 of the lower frame 232 in the component supply unit 23.

[0052] As shown in FIG. 2 , feeder 25 has upper positioning pin 256, lower positioning pin 257, and feeder-side connector 258. Upper positioning pin 256 and lower positioning pin 257 are pins provided to protrude from one end of feeder body 251 in the X-axis direction. Upper positioning pin 256 and lower positioning pin 257 are arranged at one end of feeder body 251 in the X-axis direction, spaced apart from each other in the Z-axis direction, with upper positioning pin 256 located above lower positioning pin 257. One end of feeder body 251 in the X-axis direction has a stepped portion recessed toward the other side in the X-axis direction relative to the portion where upper positioning pin 256 and lower positioning pin 257 are provided. Feeder-side connector 258 is provided at the stepped portion at one end of feeder body 251 in the X-axis direction. Feeder-side connector 258 is a connector electrically connected to control board 259.

[0053] The multiple mounting sections 24, to which the feeders 25 are attached, are formed on the upper frame 231, the lower frame 232, and the rear frame 233 of the component supply unit 23. Each mounting section 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.

[0054] A plurality of upper holding rails 241 are formed side by side in the Y-axis direction and 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 end of feeder 25 when feeder 25 moves to be inserted into or removed from mounting portion 24. A plurality of lower holding rails 242 are formed side by side in the Y-axis direction and 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 end of feeder 25 when feeder 25 moves to be inserted into or removed from mounting portion 24.

[0055] The upper pin insertion holes 243 are holes formed in a row in the Y-axis direction at the upper end of the rear frame 233. The upper pin insertion holes 243 allow upper positioning pins 256 of the feeder 25 to pass through when the feeder 25 is inserted into the mounting portion 24. On the other hand, when the feeder 25 is removed from the mounting portion 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 row in the Y-axis direction at the lower end of the rear frame 233. The lower pin insertion holes 244 allow lower positioning pins 257 of the feeder 25 to pass through when the feeder 25 is inserted into the mounting portion 24. On the other hand, when the feeder 25 is removed from the mounting portion 24, the lower positioning pins 257 are released from being inserted into the lower pin insertion holes 244. The feeder 25 is positioned relative to the mounting unit 24 by inserting the upper positioning pins 256 into the upper pin insertion holes 243 and the lower positioning pins 257 into the lower pin insertion holes 244 .

[0056] The unit-side connectors 245 are provided in a plurality of rows in the Y-axis direction on the protruding portion 2321 of the lower frame 232, and are connectors that are electrically connected to the control unit of the mounting machine 2. 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 mounting portion 24.

[0057] When mounting boards using the multiple mounting machines 2, 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 for different types of components are mounted in the mounting sections 24 and arranged in the Y-axis direction within the component supply unit 23 of each of the multiple mounting machines 2. In this case, the multiple feeders 25 are mounted in the mounting sections 24 within the component supply unit 23 so as to be arranged in an optimized manner based on the efficiency with which components are mounted on the board by the head unit 26. Specifically, the arrangement of the multiple feeders 25 within the component supply unit 23 of each of the multiple mounting machines 2 is set so as to minimize the amount of movement of the head unit 26 when mounting components on the board.

[0058] [Detailed configuration of parts replacement system] As described above, in the component replacement system 6S, the component replacement plan data D3 transmitted from the integrated management device UM is received by the replacement management device 7M and the storage management device 8M. The component replacement plan data D3 is data indicating a replacement plan for the collection and replenishment of feeders 25 for each component supply unit 23 of the first mounting machine 2A, the second mounting machine 2B, the third mounting machine 2C, and the fourth mounting machine 2D as multiple mounting machines 2. As shown in FIG. 1 , the component replacement plan data D3 is data in which component type information D31, mounting unit position information D32, and replacement period information D33 are associated with each other. The component type information D31 is information indicating the type of components stored in feeders 25 as recovery components to be recovered that are predicted to need to be recovered due to component shortages, etc., among the feeders 25 attached to each mounting unit 24 of each component supply unit 23. The mounting part position information D32 is information that indicates the position of the source mounting part 24 to which the feeder 25 serving as the collection member to be collected is attached, among the multiple mounting parts 24 in each component supply unit 23. The replacement period information D33 is information that indicates a target value of the replacement period at which the entire series of replacement work of supplying the feeder 25 serving as the supply member to be supplied from the source mounting part 24 to the supply destination is completed in response to the collection of the feeder 25 serving as the collection member to be collected from the source mounting part 24.

[0059] The component replacement system 6S will be described with reference to FIGS. 1 and 3. First, in the storage unit 81 of the storage device 8, feeders 25 are stored in an arranged state as supply materials to be supplied to each component supply unit 23 of the first mounting machine 2A, the second mounting machine 2B, the third mounting machine 2C, and the fourth mounting machine 2D based on the component replacement plan data D3. The feeders 25 as supply materials stored in the storage unit 81 of the storage device 8 are feeders to be supplied in exchange for feeders 25 as recovery materials attached to the attachment units 24 of the recovery sources indicated by the attachment unit position information D32 included in the component replacement plan data D3, and are capable of supplying components of the component types indicated by the component type information D31. The storage management device 8M manages the storage status of the feeders 25 as supply materials in the storage unit 81 of the storage device 8.

[0060] The replacement management device 7M is connected to the replacement device 7 so as to be able to communicate data with it. The replacement device 7 is movable along a movement path R, with a predetermined waiting area as its start point RS and end point RE, passing through a storage unit 81 of the storage device 8 and each of the component supply units 23 of the first mounting machine 2A, the second mounting machine 2B, the third mounting machine 2C, and the fourth mounting machine 2D. When the replacement device 7 is positioned at position P1 opposite the storage unit 81 on the movement path R, it removes feeders 25 as supply materials from the storage unit 81 and takes them in. When the replacement device 7 is positioned at position P2 opposite each of the component supply units 23 on the movement path R, it removes feeders 25 as recovery materials to be recovered from each of the component supply units 23 and recovers them inside, and inserts feeders 25 as recovery materials to be replenished into each of the component supply units 23 to perform the replacement of the feeders 25.

[0061] The exchange device 7 includes an exchange device main body 71, a support unit 72, and an operating unit 73. The exchange device main body 71 is a housing having an internal space in which the support unit 72 and the operating unit 73 are disposed. The support unit 72 has a plate-like shape extending in the X-axis and Y-axis directions, and has multiple support parts 721 provided on its upper surface. The multiple support parts 721 are configured with rails extending in the X-axis direction and are arranged on the support unit 72 so as to be aligned in the Y-axis direction. The multiple support parts 721 support the feeders 25 to be exchanged between each component supply unit 23 and the storage unit 81 so that they can be inserted and removed. In the support unit 72, the feeders 25 are inserted into the respective support parts 721, so that the multiple feeders 25 are aligned in the Y-axis direction. In the example shown in FIG. 3, eleven support parts 721a to 721k are aligned in order from one end of the support unit 72 to the other end in the Y-axis direction.

[0062] The support unit 72 is movable within a predetermined movement range MR in the Y-axis direction, which is the arrangement direction of the plurality of support portions 721a to 721k, within the exchange device main body 71. The movement range MR of the support unit 72 is set to, for example, the width of five support portions 721 in the arrangement direction of the plurality of support portions 721a to 721k. In this case, for example, when the support portion 721f at the center position CP in the arrangement direction of the plurality of support portions 721a to 721k of the support unit 72 is used as a reference, the movement range MR of the support unit 72 is the range from support portion 721d to support portion 721h, which is the two support portions on either side of support portion 721f in the arrangement direction.

[0063] The working unit 73 takes in the supply member feeders 25 from the storage unit 81 to the support unit 72, and also performs a series of replacement operations, such as retrieving the retrieved member feeders 25 and replenishing the supply member feeders 25, between each component supply unit 23 and the support unit 72. The workable range WR in which the replacement operation by the working unit 73 can be performed coincides with the movement range MR of the support unit 72 in the arrangement direction of the multiple support portions 721a to 721k on the support unit 72.

[0064] The working unit 73 includes an arm portion 731 and a hand portion 732. The arm portion 731 is movable in the space above the support unit 72 in the exchanger main body 71 in the Y-axis direction, which is the arrangement direction of the multiple support portions 721a to 721k. The hand portion 732 is movably attached to the arm portion 731 and is capable of gripping a feeder 25. The hand portion 732 is movable relative to the arm portion 731 in the X-axis direction, along which the multiple support portions 721a to 721k extend. The hand portion 732 moves in the Y-axis direction in conjunction with the movement of the arm portion 731 in the space above the support unit 72 in the exchanger main body 71, and also moves in the X-axis direction relative to the arm portion 731. The hand portion 732 moves in the X-axis direction relative to the arm portion 731 while gripping the feeder 25, thereby moving the feeder 25 so that the feeder 25 is inserted into or removed from each of the support portions 721a to 721k on the support unit 72.

[0065] When the exchange device 7 is located at position P1 on the movement path R facing the storage unit 81, the support unit 72 faces the storage unit 81. In this state, the support unit 72 moves in the Y-axis direction within a predetermined movement range MR so that a supply support portion serving as a support portion 721 supporting the feeder 25 faces a storage position of the feeder 25 as a supply member in the storage unit 81. The arm portion 731 moves in the Y-axis direction so that the hand portion 732 is positioned above a supply support portion of the multiple support portions 721 on the support unit 72. Then, the hand portion 732 moves along the X-axis direction from the storage device 8 side to the exchange device 7 side while holding the feeder 25 as a supply member. In this case, the feeder 25 as a supply member is removed from the storage unit 81, moved to the supply support portion on the support unit 72, and inserted therein. By sequentially repeating the movements of the support unit 72, the arm portion 731, and the hand portion 732, a plurality of feeders 25 as supply members are arranged side by side in the Y-axis direction on the support unit 72.

[0066] When the exchange device 7 is located at position P2 on the movement path R facing each component supply unit 23, the support unit 72 faces each component supply unit 23. In this state, the support unit 72 moves in the Y-axis direction within a predetermined movement range MR so that a recovery support portion serving as a support portion 721 supporting a feeder 25 faces a recovery source mounting portion 24 to which the feeder 25 is attached as a recovery member in each component supply unit 23. The arm portion 731 moves in the Y-axis direction so that the hand portion 732 is positioned above a recovery support portion of the multiple supports 721 on the support unit 72. Then, the hand portion 732 moves along the X-axis direction from the mounting machine 2 side to the exchange device 7 side while holding the feeder 25 as a recovery member. In this case, the feeder 25 as a recovery member is removed from the recovery source mounting portion 24 in each component supply unit 23 and moved to and inserted into the recovery support portion on the support unit 72. As a result, the feeders 25 serving as recovery members in each component supply unit 23 are recovered onto the support unit 72.

[0067] Furthermore, the support unit 72 moves in the Y-axis direction within a predetermined movement range MR so that the supply support portion supporting the feeder 25 as a supply member faces the mounting portion 24 from which the feeder 25 is to be collected. The arm portion 731 moves in the Y-axis direction so that the hand portion 732 is positioned above the supply support portion of the multiple support portions 721 on the support unit 72. Then, the hand portion 732 moves along the X-axis direction from the exchange device 7 side to the mounting machine 2 side while holding the feeder 25 as a supply member. In this case, the feeder 25 as a supply member is extracted from the supply support portion on the support unit 72 and moved to and inserted into the mounting portion 24 from which the feeder 25 is to be collected in each component supply unit 23. As a result, the feeder 25 as a supply member on the support unit 72 is replenished into each component supply unit 23 so as to be replaced with the feeder 25 as a collected member.

[0068] The exchange management device 7M manages the operation of the exchange device 7. The exchange management device 7M includes a processing unit 7M1 configured by a processor, and a storage unit 7M2.

[0069] As shown in the flowchart of FIG. 4, the processing unit 7M1 performs the following processes to manage the operation of the exchange device 7: a plan data acquisition process S1, a management data generation process S2, confirmation processes S3 and S4, an arrangement process S5, and an exchange process S6.

[0070] In the plan data acquisition process S1, the processing unit 7M1 acquires the part replacement plan data D3 including the part type information D31, the mounting part position information D32, and the replacement period information D33 from the integrated management device UM.

[0071] In the management data generation process S2, the processing unit 7M1 generates replacement management data D4 shown in Fig. 5 based on the part replacement plan data D3. The replacement management data D4 generated by the processing unit 7M1 is stored in the storage unit 7M2. The replacement management data D4 is data for managing the operation of the replacement device 7. The replacement management data D4 includes mounting part position information D41 and support arrangement data D42.

[0072] The mounting unit position information D41 is information indicating the position of the mounting unit 24 to which the feeder 25 serving as the collection member to be collected is attached in each of the component supply units 23 of the first mounting machine 2A, the second mounting machine 2B, the third mounting machine 2C, and the fourth mounting machine 2D. The position indicated by the mounting unit position information D41 matches the position indicated by the mounting unit position information D32 included in the component replacement plan data D3. In the example shown in FIG. 5, of the multiple mounting units 24a to 24k in the component supply unit 23 of the first mounting machine 2A, the feeder 25A serving as the collection member is attached to the mounting unit 24b, and the feeder 25B serving as the collection member is attached to the mounting unit 24j. Of the multiple mounting units 24a to 24k in the component supply unit 23 of the second mounting machine 2B, the feeder 25C serving as the collection member is attached to the mounting unit 24a. Of the multiple mounting parts 24a to 24k in the component supply unit 23 of the third mounting machine 2C, feeder 25D as a collecting member is mounted in mounting part 24a, and feeder 25E as a collecting member is mounted in mounting part 24h. Of the multiple mounting parts 24a to 24k in the component supply unit 23 of the fourth mounting machine 2D, feeder 25F as a collecting member is mounted in mounting part 24k.

[0073] The support arrangement data D42 is data that indicates the arrangement of the feeders 25 as collection members and supply members in the support unit 72 of the exchange device 7. In other words, the support arrangement data D42 is data that indicates the positions of the collection support parts that support the feeders 25 as collection members and the supply support parts that support the feeders 25 as supply members in the multiple support parts 721a to 721k of the support unit 72. In the example shown in Figure 5, among the multiple support parts 721a to 721k of the support unit 72, the positions of the recovery support parts are as follows: support part 721b is set as the recovery support part for recovery member feeder 25D, support part 721c is set as the recovery support part for recovery member feeder 25C, support part 721d is set as the recovery support part for recovery member feeder 25A, support part 721f is set as the recovery support part for recovery member feeder 25E, support part 721h is set as the recovery support part for recovery member feeder 25B, and support part 721i is set as the recovery support part for recovery member feeder 25F. Furthermore, among the multiple support portions 721a to 721k of the support unit 72, the positions of the supply support portions are set as follows: support portion 721a is set as the supply support portion for supply member feeder 25D, support portion 721b is set as the supply support portion for supply member feeder 25C, support portion 721c is set as the supply support portion for supply member feeder 25A, support portion 721g is set as the supply support portion for supply member feeder 25E, support portion 721i is set as the supply support portion for supply member feeder 25B, and support portion 721j is set as the supply support portion for supply member feeder 25F.

[0074] The management data generation process S2 performed by the processing unit 7M1 will be described in detail later.

[0075] The processing unit 7M1 performs confirmation processes S3 and S4 after completing the management data generation process S2 and before performing the arrangement process S5 and replacement process S6. In these confirmation processes S3 and S4, the processing unit 7M1 confirms the total work time TT required for the work unit 73 of the replacement device 7 to complete all replacement work based on the replacement management data D4. The total work time TT is the estimated total time it takes for the replacement device 7 to move from the start point RS along the movement path R, perform replacement work on each component supply unit 23 of the first mounter 2A, the second mounter 2B, the third mounter 2C, and the fourth mounter 2D, and then return to the end point RE. In other words, the total work time TT is the sum of the estimated travel time of the replacement device 7 along the movement path R, the estimated work time of the replacement device 7 at position P1 opposite the storage unit 81 on the movement path R, and the estimated work time of the replacement device 7 at position P2 opposite each component supply unit 23 on the movement path R.

[0076] In the confirmation processes S3 and S4, the processing unit 7M1 determines whether the total work time TT is within the range of the replacement cycle TC indicated in the replacement cycle information D33 included in the part replacement plan data D3. The replacement cycle TC is a target period for the replacement device 7 to move from the start point RS along the movement path R, complete all replacement work, and then return to the end point RE. If the total work time TT based on the replacement management data D4 generated in the management data generation process S2 does not fall within the range of the replacement cycle TC, the processing unit 7M1 returns to the management data generation process S2 and regenerates the replacement management data D4. On the other hand, if the total work time TT is within the range of the replacement cycle TC, the processing unit 7M1 stores the generated replacement management data D4 in the storage unit 7M2 and proceeds to the arrangement process S5.

[0077] With the exchange device 7 positioned at position P1 facing the storage unit 81 of the storage device 8 on the movement path R, the processing unit 7M1 performs arrangement processing S5 based on the exchange management data D4, as shown in Fig. 6. In the arrangement processing S5, the processing unit 7M1 moves the support unit 72, the arm portion 731, and the hand portion 732 based on data relating to the position of the supply support portion in the support arrangement data D42 included in the exchange management data D4, and arranges the feeders 25A to 25F as supply members on the support unit 72.

[0078] 6, the support unit 72 moves in the Y-axis direction within a predetermined movement range MR so that the support portion 721c serving as a supply support portion supporting the feeder 25A faces the storage position of the feeder 25A serving as a supply member in the storage unit 81. The arm portion 731 moves in the Y-axis direction so that the hand portion 732 is positioned above the support portion 721c on the support unit 72. Then, the hand portion 732 moves along the X-axis direction from the storage device 8 side to the exchange device 7 side while holding the feeder 25A serving as a supply member. As a result, the feeder 25A serving as a supply member is removed from the storage unit 81 and moved to and inserted into the support portion 721c serving as a supply support portion on the support unit 72. As the movement of the support unit 72, arm portion 731 and hand portion 732 is repeated in this manner, on the support unit 72, feeder 25A as a supply member is supported by support portion 721c, feeder 25B is supported by support portion 721i, feeder 25C is supported by support portion 721b, feeder 25D is supported by support portion 721a, feeder 25E is supported by support portion 721g, and feeder 25F is supported by support portion 721j.

[0079] When the exchange device 7 is positioned at position P2 on the movement path R facing the component supply units 23 of the first mounter 2A, the second mounter 2B, the third mounter 2C, and the fourth mounter 2D with the feeders 25A-25F as supply members arranged on the support unit 72, the processing unit 7M1 performs exchange processing S6 based on the exchange management data D4, as shown in FIG. 7. In exchange processing S6, the processing unit 7M1 confirms the positions of the mounting units 24 to which the feeders 25 as collection members are attached in each component supply unit 23 based on the mounting unit position information D41 included in the exchange management data D4, and also confirms the positions of the collection support unit and the supply support unit in the support unit 72 based on the support arrangement data D42. The processing unit 7M1 then moves the support unit 72, the arm unit 731, and the hand unit 732 to perform an exchange operation to exchange the feeders 25 between the support unit 72 and each component supply unit 23.

[0080] In the example shown in FIG. 7 , the support unit 72 moves in the Y-axis direction within a predetermined movement range MR so that the support portion 721d serving as a recovery support portion supporting the feeder 25A serving as a recovery member faces the recovery source mounting portion 24b to which the feeder 25A serving as a recovery member in the component supply unit 23 of the first mounter 2A is mounted. The arm portion 731 moves in the Y-axis direction so that the hand portion 732 is positioned above the support portion 721d serving as a recovery support portion on the support unit 72. Then, the hand portion 732 moves along the X-axis direction from the first mounter 2A side to the replacement device 7 side while holding the feeder 25A serving as a recovery member. In this case, the feeder 25A serving as a recovery member is removed from the recovery source mounting portion 24b in the component supply unit 23 and moved to and inserted into the support portion 721d serving as a recovery support portion on the support unit 72. As a result, the feeder 25A serving as a recovery member in the component supply unit 23 is recovered onto the support unit 72.

[0081] The support unit 72 also moves in the Y-axis direction within a predetermined movement range MR so that the support portion 721c serving as a supply support portion supporting the feeder 25A of the supply member faces the mounting portion 24b of the collection source. The arm portion 731 moves in the Y-axis direction so that the hand portion 732 is positioned above the support portion 721c serving as a supply support portion on the support unit 72. The hand portion 732 then moves along the X-axis direction from the exchange device 7 side to the first mounter 2A side while holding the feeder 25A as the supply member. In this case, the feeder 25A as the supply member is removed from the support portion 721c serving as a supply support portion on the support unit 72 and moved to and inserted into the mounting portion 24b of the collection source in the component supply unit 23. As a result, the feeder 25A as the supply member on the support unit 72 is supplied into the component supply unit 23 so as to be replaced with the feeder 25A as the collection member.

[0082] [Details of the management data generation process of the exchange management device] The management data generation process S2 performed by the processing unit 7M1 of the exchange management device 7M will be described in detail with reference to FIGS.

[0083] As described above, in the management data generation process S2, the processing unit 7M1 generates replacement management data D4 including mounting part position information D41 and support arrangement data D42 based on the part replacement plan data D3. In this management data generation process S2, the processing unit 7M1 performs a selection process S21, an extraction process S22, a recognition process S23, and a setting process S24.

[0084] In the selection process S21, the processing unit 7M1 selects a plurality of feeders 25 as recovery members to be recovered from among the feeders 25 mounted on each mounting portion 24 of each component supply unit 23 of the first mounting machine 2A, the second mounting machine 2B, the third mounting machine 2C, and the fourth mounting machine 2D, based on mounting portion position information D32 included in the component replacement plan data D3. Then, the processing unit 7M1 generates mounting portion position information D41 related to the plurality of feeders 25 as the selected recovery members.

[0085] 9, the processing unit 7M1 selects as collection members feeders 25A and 25B attached to mounting portion 24b and mounting portion 24j of the component supply unit 23 of the first mounting machine 2A, feeder 25C attached to mounting portion 24a of the component supply unit 23 of the second mounting machine 2B, feeder 25D and feeder 25E attached to mounting portion 24a and mounting portion 24h of the component supply unit 23 of the third mounting machine 2C, and feeder 25F attached to mounting portion 24k of the component supply unit 23 of the fourth mounting machine 2D. At this time, the processing unit 7M1 selects the multiple feeders 25A to 25F as collection members in collection priority order PO, which indicates the order of collection priority, such as the earliest expected time of component shortage. The collection priority order PO of the selected feeders 25A to 25F is assumed to be feeder 25C, feeder 25A, feeder 25E, feeder 25D, feeder 25B, and feeder 25F in order from top to bottom.

[0086] In an extraction process S22 following the selection process S21, the processing unit 7M1 extracts a predetermined number of feeders 25 as extraction / recovery members from among the multiple feeders 25A-25F selected in the selection process S21 as recovery members. The predetermined number can be set to any number equal to or greater than 1. In the example shown in FIG. 9, the predetermined number is set to "2." The processing unit 7M1 also sorts the multiple feeders 25A-25F selected in the selection process S21 as recovery members in order of recovery priority PO and extracts the two feeders 25C and 25A with the highest recovery priority PO as extraction / recovery members. In this case, in a setting process S24 following the extraction process S22 by the processing unit 7M1, the positions of the recovery support portion and the supply support portion of the support unit 72 can be set with priority given to the feeders 25 with the highest recovery priority PO as recovery members.

[0087] In a recognition process S23 after the processing unit 7M1 has extracted the two feeders 25C and 25A with the highest collection priority order PO as the extracted and collected components, the processing unit 7M1 recognizes the work order WO of the replacement work to be performed by the working unit 73 corresponding to the two feeders 25C and 25A as the extracted and collected components, in accordance with the order in which the replacement device 7 moving along the movement path R arrives at each component supply unit 23. In the example shown in Fig. 9, the processing unit 7M1 recognizes that the feeder 25A attached to the attachment portion 24b of the component supply unit 23 of the first mounting machine 2A is higher in the work order WO than the feeder 25C attached to the attachment portion 24a of the component supply unit 23 of the second mounting machine 2B.

[0088] In setting process S24 following recognition process S23, the processing unit 7M1 sets the positions of the collection support part and the supply support part of the support unit 72 in the work order WO for two feeders 25A and 25C as extraction and recovery members, as shown in Fig. 10, and records the setting result in support arrangement data D42. In this case, taking into consideration that the exchange device 7 moves along the movement path R, the positions of the collection support part and the supply support part of the support unit 72 can be set in the work order WO of the replacement work performed by the working unit 73. In other words, the processing unit 7M1 sets the positions of the collection support part and the supply support part of the support unit 72 for feeder 25A, which is higher in the work order WO, and then sets the positions of the collection support part and the supply support part of the support unit 72 for feeder 25C.

[0089] Specifically, when setting the positions of the recovery support portion and the supply support portion of the support unit 72 for the feeder 25A as the extraction and recovery member, the processing unit 7M1 recognizes the support portion 721b, among the multiple supports 721a-721k of the support unit 72, that is positioned opposite the mounting portion 24b to which the feeder 25A is mounted on the component supply unit 23 of the first mounter 2A as the reference position SP. Then, the processing unit 7M1 sets the supports 721a, 721b, 721c, and 721d within the movement range MR of the support unit 72, which corresponds to the workable range WR of the working unit 73, relative to the reference position SP as setting candidates, and from the setting candidates, sets the support portion 721d as the recovery support portion supporting the feeder 25A as the extraction and recovery member, and sets the support portion 721c as the supply support portion supporting the feeder 25A of the supply member corresponding to the extraction and recovery member. The processing unit 7M1 records the setting results in the support arrangement data D42.

[0090] Next, when setting the positions of the recovery support portion and the supply support portion in the support unit 72 for feeder 25C as an extraction and recovery member lower in the work order WO than feeder 25A, the processing unit 7M1 recognizes, among the multiple support portions 721a to 721k of the support unit 72, the support portion 721a located opposite the mounting portion 24a to which feeder 25C is mounted on the component supply unit 23 of the second mounting machine 2B as the reference position SP. Then, among the supports 721a, 721b, and 721c within the movement range MR of the support unit 72 relative to the reference position SP, the processing unit 7M1 excludes from the setting candidates support 721d that has already been set as a recovery support for the feeder 25A that is higher in the work order WO, but includes support 721c that has already been set as a supply support, and sets support 721c as the recovery support supporting feeder 25C of the extraction and recovery member, and sets support 721b as the supply support supporting feeder 25C of the supply member corresponding to the extraction and recovery member. The processing unit 7M1 records the setting results in the support arrangement data D42.

[0091] The positions of the recovery support portion and the supply support portion on the support unit 72 recorded in the support arrangement data D42 are set within the movement range MR of the support unit 72, which corresponds to the workable range WR within which the replacement work by the working unit 73 can be performed, with the support portion 721 at a position facing the mounting portion 24 to which the extraction and recovery member is attached on the component supply unit 23 as the reference position SP. In this case, when the working unit 73 performs the replacement work based on the support arrangement data D42 in the replacement process S6 after the management data generation process S2 by the processing unit 7M1, it is possible to accurately recover the recovery member feeder 25 from the recovery source mounting portion 24 of the component supply unit 23 facing the support portion 721 at the reference position SP of the support unit 72 to the recovery support portion of the support unit 72, and it is also possible to accurately supply the supply member feeder 25 from the supply support portion of the support unit 72 to the recovery source mounting portion 24 as the supply destination.

[0092] Furthermore, the positions of the recovery support portion and the supply support portion on the support unit 72 are set within the movement range MR of the support unit 72 with respect to the reference position SP. In this case, when the working unit 73 performs replacement work based on the support arrangement data D42, when the support unit 72 moves within the movement range MR so that the recovery support portion faces the recovery source mounting portion 24 of the component supply unit 23, it is possible to accurately recover the recovery material feeder 25 from the recovery source mounting portion 24 to the recovery support portion. On the other hand, when the support unit 72 moves within the movement range MR so that the supply support portion faces the recovery source mounting portion 24 of the component supply unit 23, it is possible to accurately supply the supply material feeder 25 from the supply support portion with the recovery source mounting portion 24 as the supply destination.

[0093] Furthermore, in the setting process S24, when setting the positions of the recovery support section and the supply support section in the support unit 72 in the work sequence WO for the two feeders 25A and 25C as extraction and recovery members, the processing unit 7M1 may set the positions of the recovery support section and the supply support section by prioritizing positions close to the central position CP in the arrangement direction of the multiple support sections 721a to 721k within the movement range MR of the support unit 72 relative to the reference position SP, as shown in Figure 10.

[0094] Specifically, when setting the positions of the recovery support portion and the supply support portion in the support unit 72 for the feeder 25A as the extraction and recovery member, the processing unit 7M1 sets support portions 721a, 721b, 721c, and 721d within the movement range MR of the support unit 72 relative to the reference position SP as setting candidates, and from these setting candidates, sets support portion 721d closest to the central position CP as the recovery support portion supporting the feeder 25A of the extraction and recovery member, and sets support portion 721c adjacent to support portion 721d as the supply support portion supporting the feeder 25A of the supply member corresponding to the extraction and recovery member.

[0095] Next, when setting the positions of the recovery support portion and the supply support portion in the support unit 72 for feeder 25C as an extraction and recovery member that is lower in the work order WO than feeder 25A, the processing unit 7M1 excludes support portion 721d that has already been set as a recovery support portion for feeder 25A, which is higher in the work order WO, from the setting candidates among support portions 721a, 721b, and 721c within the movement range MR of the support unit 72 relative to the reference position SP, but includes support portion 721c that has already been set as a supply support portion, and sets support portion 721c closest to the central position CP as the recovery support portion that supports feeder 25C of the extraction and recovery member, and sets support portion 721b adjacent to support portion 721c as the supply support portion that supports feeder 25C of the supply member corresponding to the extraction and recovery member.

[0096] In this way, the positions of the recovery support parts and supply support parts on the support unit 72 are set with priority to positions close to the center position CP in the arrangement direction within the movement range MR of the support unit 72 with respect to the reference position SP. In this case, even if the reference positions SP facing the respective recovery source mounting parts 24 in the support unit 72 are biased toward the end positions in the arrangement direction due to bias in the positions of the recovery source mounting parts 24 to which the recovery member feeders 25 are attached in each component supply unit 23, the positions of the recovery support parts and supply support parts on the support unit 72 can be set for the relatively large number of recovery member feeders 25 attached to the respective recovery source mounting parts 24.

[0097] Furthermore, in the setting process S24, when setting the positions of the recovery support section and the supply support section in the support unit 72 in the work sequence WO for the two feeders 25A and 25C as extraction and recovery members, the processing unit 7M1 may set the positions of the recovery support section and the supply support section by prioritizing positions close to the reference position SP within the movement range MR of the support unit 72 relative to the reference position SP, as shown in Figure 13.

[0098] Specifically, when setting the positions of the recovery support portion and the supply support portion in the support unit 72 for the feeder 25A as the extraction and recovery member, the processing unit 7M1 sets support portions 721a, 721b, 721c, and 721d within the movement range MR of the support unit 72 relative to the reference position SP as setting candidates, and from these setting candidates, sets support portion 721b closest to the reference position SP as the recovery support portion supporting the feeder 25A of the extraction and recovery member, and sets support portion 721a adjacent to support portion 721b within the movement range MR as the supply support portion supporting the feeder 25A of the supply member corresponding to the extraction and recovery member.

[0099] Next, when setting the positions of the recovery support portion and the supply support portion in the support unit 72 for feeder 25C as an extraction and recovery member that is lower in the work order WO than feeder 25A, the processing unit 7M1 excludes from the setting candidates, among the support portions 721a, 721b, and 721c within the movement range MR of the support unit 72 relative to the reference position SP, support portion 721b that has already been set as a recovery support portion for feeder 25A, which is higher in the work order WO, but includes support portion 721a that has already been set as a supply support portion, and sets support portion 721a closest to the reference position SP as the recovery support portion that supports feeder 25C of the extraction and recovery member, and sets support portion 721c within the movement range MR as the supply support portion that supports feeder 25C of the supply member corresponding to the extraction and recovery member.

[0100] In this way, the positions of the recovery support section and the supply support section on the support unit 72 are set with priority to positions closest to the reference position SP within the movement range MR of the support unit 72 with respect to the reference position SP. In this case, when the working unit 73 performs replacement work based on the support array data D42, the amount of movement within the movement range MR of the support unit 72 can be made as small as possible. This makes it possible to improve the efficiency of the replacement work.

[0101] As shown in the flowchart of FIG. 8, the processing unit 7M1 repeatedly performs the extraction process S22, the recognition process S23, and the setting process S24 after the selection process S21 until a predetermined termination condition is met.

[0102] The processing unit 7M1 determines whether or not the setting of the positions of the collection support parts and supply support parts has been completed in the setting process S24 for all of the multiple collection member feeders 25A-25F selected in the selection process S21 (step S25). When the setting of all of the multiple collection member feeders 25A-25F selected in the selection process S21 has been completed (YES in step S25), the processing unit 7M1 ends the repetition of the extraction process S22, the recognition process S23, and the setting process S24, thereby ending the management data generation process S2, and outputs replacement management data D4 including the support array data D42 at that time.

[0103] The processing unit 7M1 also determines whether the expected load weight when the collection member feeder 25 is supported by the collection support section and the supply member feeder 25 is supported by the supply support section set in the setting process S24 reaches the allowable load weight LW (step S26), using the predetermined allowable load weight LW of the support unit 72 as an end condition. When the expected load weight reaches the allowable load weight LW (YES in step S26), the processing unit 7M1 ends the repetition of the extraction process S22, the recognition process S23, and the setting process S24, thereby ending the management data generation process S2, and outputs the replacement management data D4 including the support array data D42 at that time. In this case, in the replacement process S6 following the management data generation process S2, the processing unit 7M1 can cause the work unit 73 to perform replacement work based on the support arrangement data D42 which records the setting results of each position of the recovery support section and supply support section of the support unit 72 set in the setting process S24 until the expected load weight reaches the allowable load weight LW.

[0104] The processing unit 7M1 also determines whether the allowable processing time PT has elapsed since the start of the management data generation process S2, using a predetermined allowable processing time PT as an end condition (step S27). When the allowable processing time PT has elapsed (YES in step S27), the processing unit 7M1 ends the management data generation process S2 by ending the repetition of the extraction process S22, the recognition process S23, and the setting process S24, and outputs replacement management data D4 including the support array data D42 at that time. In this case, in the replacement process S6 following the management data generation process S2, the processing unit 7M1 can cause the working unit 73 to perform the replacement work based on the support array data D42 that records the setting results of the positions of the collection support portion and the supply support portion of the support unit 72 that were set in the setting process S24 before the allowable processing time PT has elapsed.

[0105] With reference to Figures 11 and 12, we will explain how the processing unit 7M1 repeatedly performs the extraction process S22, the recognition process S23 and the setting process S24 for two feeders 25A and 25C as extraction and recovery members after setting the positions of the recovery support section and the supply support section in the support unit 72.

[0106] In extraction processing S22, processing unit 7M1 extracts two feeders 25E and 25D, which have the next highest collection priority order PO after feeder 25A and feeder 25C, as extracted and collected components. Then, in recognition processing S23, processing unit 7M1 recognizes the work order WO of the replacement work to be performed by working unit 73 corresponding to the two feeders 25E and 25D as extracted and collected components. In the example shown in Figure 11, processing unit 7M1 recognizes that feeder 25D attached to attachment portion 24a of component supply unit 23 of third mounting machine 2C has a higher work order WO than feeder 25E attached to attachment portion 24h of component supply unit 23 of third mounting machine 2C. Furthermore, the processing unit 7M1 recognizes that the work order WO of the replacement work performed by the work unit 73 corresponding to feeder 25A, feeder 25C, feeder 25D and feeder 25E is, from top to bottom, feeder 25A, feeder 25C, feeder 25D, feeder 25E.

[0107] In the setting process S24 following the recognition process S23, the processing unit 7M1 sets the positions of the recovery support section and the supply support section in the support unit 72 in the work order WO for the two feeders 25D and 25E as extraction and recovery members, and records the setting results in the support arrangement data D42.

[0108] Specifically, when setting the positions of the recovery support portion and supply support portion in the support unit 72 for feeder 25D as an extraction and recovery member, the processing unit 7M1 takes into consideration the set support portions 721 of support portions 721a, 721b, and 721c within the movement range MR of the support unit 72 relative to the reference position SP, sets support portion 721b closest to the central position CP as the recovery support portion supporting feeder 25D as the extraction and recovery member, and sets support portion 721a adjacent to support portion 721b within the movement range MR as the supply support portion supporting feeder 25D as the supply member corresponding to the extraction and recovery member. The processing unit 7M1 records the setting results in support arrangement data D42.

[0109] Next, when setting the positions of the recovery support portion and supply support portion of the support unit 72 for feeder 25E as an extraction and recovery member that is lower in the work order WO than feeder 25D, the processing unit 7M1 takes into consideration the set support portions 721 of support portions 721f, 721g, 721h, 721i, and 721j within the movement range MR of the support unit 72 relative to the reference position SP, sets support portion 721f closest to the central position CP as the recovery support portion supporting feeder 25E as the extraction and recovery member, and sets support portion 721g adjacent to support portion 721f within the movement range MR as the supply support portion supporting feeder 25E as the supply member corresponding to the extraction and recovery member. The processing unit 7M1 records the setting results in support arrangement data D42.

[0110] With reference to Figure 12, we will explain the case where the processing unit 7M1 repeatedly performs the extraction process S22, the recognition process S23 and the setting process S24 for the two feeders 25D and 25E as extraction and recovery members after setting the positions of the recovery support section and the supply support section in the support unit 72.

[0111] In extraction processing S22, processing unit 7M1 extracts two feeders 25B and 25F, which have the next highest collection priority order PO after feeders 25D and 25E, as extracted and collected components. Then, in recognition processing S23, processing unit 7M1 recognizes the work order WO of the replacement work to be performed by working unit 73 corresponding to two feeders 25B and 25F as extracted and collected components. In the example shown in Fig. 11, processing unit 7M1 recognizes that feeder 25B attached to mounting portion 24j of component supply unit 23 of first mounting machine 2A is higher in work order WO than feeder 25F attached to mounting portion 24k of component supply unit 23 of fourth mounting machine 2D. In addition, the processing unit 7M1 recognizes that the work order WO of the replacement work performed by the work unit 73 corresponding to feeder 25A, feeder 25B, feeder 25C, feeder 25D, feeder 25E and feeder 25F is, from top to bottom, feeder 25A, feeder 25B, feeder 25C, feeder 25D, feeder 25E, feeder 25F.

[0112] In the setting process S24 following the recognition process S23, the processing unit 7M1 sets the positions of the recovery support section and the supply support section in the support unit 72 in the work order WO for the two feeders 25B and 25F as extraction and recovery members, and records the setting results in the support arrangement data D42.

[0113] Specifically, when setting the positions of the recovery support portion and supply support portion in the support unit 72 for feeder 25B as an extraction and recovery member, the processing unit 7M1 takes into consideration the set support portions 721 of support portions 721h, 721i, 721j, and 721k within the movement range MR of the support unit 72 relative to the reference position SP, sets support portion 721h closest to the central position CP as the recovery support portion supporting feeder 25B of the extraction and recovery member, and sets support portion 721i adjacent to support portion 721h within the movement range MR as the supply support portion supporting feeder 25B of the supply member corresponding to the extraction and recovery member. The processing unit 7M1 records the setting results in support arrangement data D42.

[0114] Next, when setting the positions of the recovery support portion and the supply support portion of the support unit 72 for feeder 25F as an extraction and recovery member that is lower in the work order WO than feeder 25B, the processing unit 7M1 takes into consideration the set support portions 721 of support portions 721i, 721j, and 721k within the movement range MR of the support unit 72 relative to the reference position SP, sets support portion 721i closest to the central position CP as the recovery support portion supporting feeder 25F of the extraction and recovery member, and sets support portion 721j adjacent to support portion 721i within the movement range MR as the supply support portion supporting feeder 25F of the supply member corresponding to the extraction and recovery member. The processing unit 7M1 records the setting results in support arrangement data D42.

[0115] As described above, by repeatedly performing the extraction process S22, the recognition process S23 and the setting process S24 by the processing unit 7M1, it is possible to set the positions of the recovery support section and the supply support section in the support unit 72 for as many recovery member feeders 25A to 25F as possible.
