Description

Technical Field

[0001] The present invention relates to a component mounting system including a replenishing device for replenishing a feeder to a component supply unit of a component mounter.

Background Art

[0002] A component mounting system includes a plurality of mounting lines including a component mounter for mounting components on a substrate such as a printed circuit board. In the mounting line, the component mounter includes a component supply unit in which feeders for supplying components are arranged, and a head unit for mounting the components supplied by the feeders on the substrate. In the component mounter, when a feeder with component depletion or the like occurs is collected from the component supply unit, a new feeder is replenished to the component supply unit in response to the collection.

[0003] Patent Document 1 discloses a component mounting system including a replenishing device for replenishing a feeder to each component mounter in response to collection of feeders from a plurality of component mounters. The replenishing device includes a traveling body that travels between a component storage and each component mounter, a moving table movably provided on the traveling body, and a replenishing unit mounted on the moving table. When the replenishing device is arranged so as to face the component storage by traveling of the traveling body, the operator transfers the feeder from the component storage to the replenishing unit. Thereby, the feeders are arranged in the replenishing unit. In this state, when the replenishing device is arranged so as to face each component supply unit of each component mounter by traveling of the traveling body, the feeder is replenished from the replenishing unit to each component supply unit while the moving table moves.

[0004] In the component mounting system disclosed in Patent Document 1, each component mounter is arranged linearly along the conveyance direction of the substrate, and the component storage is arranged at a position spaced apart from each component mounter in the conveyance direction. In this case, the moving time when the replenishing device moves from the component storage to each component mounter becomes longer as it goes downstream in the conveyance direction of the substrate. For the component mounter located far from the component storage, the moving time of the replenishing device becomes longer, the efficiency of replenishing the feeder by the replenishing device decreases, and there is a risk that the replenishment of the feeder cannot be completed within the replenishment allowable time.

Embodiments for Carrying Out the Invention

[0010] Hereinafter, a component mounting system according to an embodiment of the present invention will be described with reference to the drawings.

[0011] The component mounting system 1 shown in FIG. 1 is a system for producing a component mounting substrate on which components such as electronic components are mounted on a substrate such as a printed circuit board. The component mounting system 1 includes a plurality of mounting lines 2 including a component mounter 2B, a first storage device 3, a second storage device 4, a replenishment device 5, and a management device 6.

[0012] [Regarding the mounting line] Each of the plurality of mounting lines 2 is installed in a predetermined production area AR1 and includes a plurality of component mounters 2B arranged along the conveyance direction of the substrate. The plurality of mounting lines 2 are installed in the production area AR1 so as to be arranged at a predetermined interval from each other in a direction intersecting the conveyance direction of the substrate. FIG. 1 shows an example in which a total of eight mounting lines 2, namely, the first mounting line 2A1, the second mounting line 2A2, the third mounting line 2A3, the fourth mounting line 2A4, the fifth mounting line 2A5, the sixth mounting line 2A6, the seventh mounting line 2A7, and the eighth mounting line 2A8, are arranged side by side in a direction intersecting the conveyance direction of the substrate.

[0013] Regarding each component mounter 2B in the plurality of mounting lines 2, it will be described with reference to FIG. 2. Hereinafter, regarding the direction relationship, it will be described using the XYZ orthogonal coordinate axes. The X-axis direction and the Y-axis direction are orthogonal to each other on the horizontal plane, and the Z-axis direction extends in the vertical direction orthogonal to both the X-axis direction and the Y-axis direction. The conveyance direction of the substrate between the component mounters 2B in the mounting line 2 coincides with the Y-axis direction.

[0014] The component mounter 2B is a device that mounts components on a substrate to produce a component-mounted substrate. Before mounting components by the component mounter 2B, a solder paste pattern is printed on the substrate. The component mounter 2B includes a mounter main body 21, a conveying conveyor 22, a component supply unit 23, and a head unit 26.

[0015] The mounter main body 21 is a housing having an internal space in which each part constituting the component mounter 2B is arranged. The conveying conveyor 22 extends in the Y-axis direction and is arranged in a substantially central region inside the mounter main body 21. The conveying conveyor 22 conveys the substrate in the Y-axis direction. The head unit 26 mounts components on the substrate conveyed by the conveying conveyor 22. The head unit 26 takes out components from a feeder 25 arranged in the component supply unit 23 and mounts the taken-out components on the substrate. A plurality of suction nozzles 261 are attached to the head unit 26. The suction nozzle 261 is a holder capable of sucking and holding components. The suction nozzle 261 can communicate with any one of a negative pressure generator, a positive pressure generator, and the atmosphere via an electric switching valve. That is, by supplying negative pressure to the suction nozzle 261, it becomes possible to suck and hold the component by the suction nozzle 261, and then, by supplying positive pressure, the suction and holding of the component are released.

[0016] The component supply unit 23 is arranged in the end region in the X-axis direction of the mounter main 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 portions 24 that support a feeder 25 for supplying components in an insertable and removable manner. The upper frame 231 is a plate-shaped frame that extends in the X-axis direction and the Y-axis direction. One end region of the upper frame 231 in the X-axis direction is exposed outward from the mounter main body 21, and the other end region in the X-axis direction is arranged at one end portion in the X-axis direction of the mounter main body 21 so as to be accommodated inside the mounter main body 21. The lower frame 232 is a plate-shaped frame that extends in the X-axis direction and the Y-axis direction, and is arranged so as to face the upper frame 231 on the lower side in the Z-axis direction with respect to the upper frame 231. The lower frame 232 has a protruding portion 2321 that protrudes upward in the Z-axis direction in the region portion on the other end side in the X-axis direction that is accommodated inside the mounter main body 21. The rear frame 233 is a plate-shaped frame that extends in the Y-axis direction and the Z-axis direction, and is arranged at a position closer to the center of the mounter main body 21 than the other end in the X-axis direction of the upper frame 231 and the lower frame 232 inside the mounter main body 21.

[0017] Each of the plurality of supply support portions 24 supports the feeder 25 in an insertable and removable manner in the component supply unit 23. In the component supply unit 23, the plurality of supply support portions 24 are arranged so as to be aligned in the Y-axis direction. By inserting the feeder 25 into each such supply support portion 24, the plurality of feeders 25 are arranged side by side in the Y-axis direction.

[0018] Feeder 25 is a component feeder for supplying components. The component supply method of the feeder 25 is not particularly limited as long as it is configured to be able to supply components. As the feeder 25, 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 components are placed, a stick feeder that supplies components while pushing out the components stored in a cylindrical stick, etc. can be adopted. Also, a bulk feeder to which a bulk cassette containing components in a bulk state in which a plurality of components are assembled is detachably attached may be adopted as the feeder 25.

[0019] Hereinafter, the case where a tape feeder is adopted as the feeder 25 will be described. The feeder 25 supplies components by sending out a component storage tape PT that can store a plurality of components. The component storage tape PT is composed of a carrier tape PT1 provided with a plurality of storage parts for storing components and a cover tape PT2 joined to the carrier tape PT1 so as to cover the storage parts. The feeder 25 includes a feeder body 251, a reel support part 252, a tape sending part 254, and a recovery part 255.

[0020] A tape sending path 253 is formed in the feeder body 251. The tape sending path 253 is a path through which the component storage tape PT is sent out, and has a component taking-out part 2531 between the upstream end and the downstream end in the sending direction of the component storage tape PT. The reel support part 252 is arranged on the upstream end side of the tape sending path 253 in the feeder body 251. The reel support part 252 supports a reel around which the component storage tape PT is wound.

[0021] The tape feeding unit 254 is composed of, for example, sprockets and is arranged near the component extraction section 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 sends out the fed-out 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 sent out along the tape feeding path 253, the cover tape PT2 is peeled off from the carrier tape PT1 upstream of the component extraction section 2531. As a result, the components are exposed on the carrier tape PT1 at the component extraction section 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 extraction section 2531.

[0022] The cover tape PT2 peeled off from the carrier tape PT1 upstream of the component extraction section 2531 is recovered by the recovery unit 255. The recovery unit 255 is composed of, for example, a pair of rollers in contact with each other. In this case, the recovery unit 255 recovers the cover tape PT2 according to the rotation of the pair of rollers. The cover tape PT2 recovered by the recovery unit 255 is accommodated in the recovery box 2551.

[0023] After the components are taken out by the head unit 26, the carrier tape PT1 is sent out outward from the feeder 25 through the downstream end of the tape feeding path 253 by the feeding operation of the tape feeding unit 254. The carrier tape PT1 sent out outward from the feeder 25 is cut to a predetermined length by a tape cutter 23A arranged near the protruding portion 2321 of the lower frame 232 in the component supply unit 23.

[0024] Also, 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 portion of the feeder body 251 in the X-axis direction. The upper positioning pin 256 and the lower positioning pin 257 are arranged at intervals in the Z-axis direction at one end portion of the feeder body 251 in the X-axis direction, and the upper positioning pin 256 is located on the upper side of the lower positioning pin 257. One end portion of the feeder body 251 in the X-axis direction has a stepped portion recessed on the other side in the X-axis direction with respect to the portion where the upper positioning pin 256 and the lower positioning pin 257 are provided. The feeder-side connector 258 is provided at the stepped portion at one end portion of the feeder body 251 in the X-axis direction. The feeder-side connector 258 is a connector that is electrically connected to the control board 259.

[0025] A plurality of supply support portions 24 for supporting the feeder 25 in an insertable and removable manner are formed on the upper frame 231, the lower frame 232, and the back frame 233 in the component supply unit 23. Each supply support portion 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.

[0026] A plurality of upper holding rails 241 are formed side by side in the Y-axis direction so as to extend in the X-axis direction on the lower surface of the upper frame 231. The upper holding rail 241 is a rail member that guides the upper end of the feeder 25 during the movement when inserting and removing the feeder 25 with respect to the supply support portion 24. A plurality of lower holding rails 242 are formed side by side in the Y-axis direction so as to extend in the X-axis direction on the upper surface of the lower frame 232. The lower holding rail 242 is a rail member that guides the lower end of the feeder 25 during the movement when inserting and removing the feeder 25 with respect to the supply support portion 24.

[0027] The upper pin insertion holes 243 are a plurality of holes formed side by side in the Y-axis direction at the upper end of the back frame 233. The upper pin insertion holes 243 allow the upper positioning pins 256 of the feeder 25 to be inserted when the feeder 25 is inserted into the supply support portion 24. On the other hand, when the feeder 25 is withdrawn from the supply support portion 24, the insertion of the upper positioning pins 256 into the upper pin insertion holes 243 is released. The lower pin insertion holes 244 are a plurality of holes formed side by side in the Y-axis direction at the lower end of the back frame 233. The lower pin insertion holes 244 allow the lower positioning pins 257 of the feeder 25 to be inserted when the feeder 25 is inserted into the supply support portion 24. On the other hand, when the feeder 25 is withdrawn from the supply support portion 24, the insertion of the lower positioning pins 257 into the lower pin insertion holes 244 is released. The feeder 25 is positioned with respect to the supply support portion 24 when the upper positioning pins 256 are inserted into the upper pin insertion holes 243 and the lower positioning pins 257 are inserted into the lower pin insertion holes 244.

[0028] The unit-side connectors 245 are a plurality of connectors provided side by side in the Y-axis direction at the protruding portions 2321 of the lower frame 232 and are electrically connected to the control unit 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.

[0029] During the production of the component mounting substrate in the component mounter 2B, a plurality of types of components are mounted on each substrate. Furthermore, the types of components mounted differ for each type of substrate. For this reason, a plurality of feeders 25 with different component types are arranged in the Y-axis direction while being supported by the supply support portions 24 within the component supply unit 23. In this case, the plurality of feeders 25 are supported by each supply support portion 24 within the component supply unit 23 so as to form an optimized arrangement based on the component mounting efficiency of the head unit 26 with respect to the substrate. Specifically, the arrangement of the plurality of feeders 25 within the component supply unit 23 is set such that the movement amount of the head unit 26 during component mounting on the substrate is minimized.

[0030] [Regarding the First Storage Device] As shown in FIG. 1, the first storage device 3 is installed in a preparation area AR2 adjacent to the production area AR1. The preparation area AR2 is an area adjacent to the production area AR1 in the X-axis direction intersecting the Y-axis direction, which is the substrate conveyance direction between the component mounters 2B. In the preparation area AR2, an operator or a work robot prepares a supply feeder 25 for replenishing each component supply unit 23 of the component mounters 2B in the plurality of mounting lines 2. The operator or the work robot replenishes the prepared supply feeder 25 to the first storage device 3. The first storage device 3 stores a plurality of feeders 25 with different component types in an arranged state in a predetermined direction. At a position adjacent to the first storage device 3 within the preparation area AR2, a first recovery device 30 is installed. The first recovery device 30 is a device for accommodating the feeder 25 from which component shortage or the like has occurred, recovered from each component mounter 2B. Note that FIG. 1 shows an example in which one first storage device 3 and one first recovery device 30 are installed in the preparation area AR2, but the number of installations is not limited thereto. A plurality of first storage devices 3 and a plurality of first recovery devices 30 may be installed in the preparation area AR2.

[0031] In a state where the first storage device 3 is installed in the preparation area AR2, the plurality of mounting lines 2 are installed in the production area AR1 such that the separation distances from the first storage device 3 are different from each other. Hereinafter, in the first to eighth mounting lines 2A1 to 2A8 as a plurality of mounting lines 2 arranged in the X-axis direction intersecting the Y-axis direction, which is the substrate conveyance direction between the component mounters 2B, the first to third mounting lines 2A1 to 2A3 with a separation distance from the first storage device 3 less than a predetermined distance are referred to as the first specific mounting line 2, and the fourth to eighth mounting lines 2A4 to 2A8 with a separation distance from the first storage device 3 equal to or greater than the predetermined distance are referred to as the second specific mounting line 2. Among the first to eighth mounting lines 2A1 to 2A8, the first mounting line 2A1 belonging to the first specific mounting line 2 has the shortest separation distance from the first storage device 3, and the eighth mounting line 2A8 belonging to the second specific mounting line 2 has the longest separation distance from the first storage device 3.

[0032] The first storage device 3 will be described with reference to FIG. 3. The first storage device 3 includes a first storage device main body 31 and a first storage unit 32.

The plurality of first storage support parts 321 are constituted by rails extending in the X-axis direction and are arranged side by side in the Y-axis direction. The plurality of first storage support parts 321 support a plurality of feeders 25 of different component types in an insertable and removable manner. In the first storage unit 32, when the feeders 25 are inserted into the respective first storage support parts 321, the plurality of feeders 25 are arranged side by side in the Y-axis direction.

[0033] In the example shown in FIG. 3, seven first storage support parts 321a to 321g are arranged in order from one end to the other end in the Y-axis direction in the first storage unit 32. The first storage support parts 321a to 321g support the feeders 25A to 25G respectively. The insertion of the feeders 25 into the respective first storage support parts 321a to 321g in the first storage unit 32 is performed by an operator or a work robot in the preparation area AR2. On the other hand, the extraction of the feeders 25 from the respective first storage support parts 321a to 321g in the first storage unit 32 is performed by the replenishment device 5 described later from the production area AR1 side.

[0034] [Regarding the second storage device] As shown in FIG. 1, the second storage device 4 is installed at a position separated from a plurality of mounting lines 2 in the production area AR1. Specifically, the second storage device 4 is installed at a position separated from the plurality of mounting lines 2 in the Y-axis direction, which is the substrate conveyance direction between the component mounters 2B. The second storage device 4 is installed at a position closer to the second specific mounting line 2 than the first storage device 3, where the separation distance from the first storage device 3 is equal to or greater than a predetermined distance. That is, the second storage device 4 is installed at a position closer to the second specific mounting line 2 than the first storage device 3 with respect to the fourth to eighth mounting lines 2A4 to 2A8 belonging to the second specific mounting line 2. The second storage device 4 stores a plurality of feeders 25 with different component types in a state arranged in a predetermined direction. At a position adjacent to the second storage device 4 within the production area AR1, a second recovery device 40 is installed. The second recovery device 40 is a device for accommodating the feeders 25 from which component shortages or the like have occurred and recovered from each component mounter 2B. In FIG. 1, an example in which one second storage device 4 and one second recovery device 40 are installed in the production area AR1 is shown, but the number of installations is not limited to this. A plurality of second storage devices 4 and a plurality of second recovery devices 40 may be installed in the production area AR1.

[0035] The second storage device 4 will be described with reference to FIG. 4. The second storage device 4 includes a second storage device main body 41 and a second storage unit 42. The second storage device main body 41 is a housing having an internal space in which the second storage unit 42 is disposed. The second storage unit 42 has a plurality of second storage support portions 421 disposed within the second storage device main body 41. The plurality of second storage support portions 421 are constituted by rails extending in the X-axis direction and are arranged side by side in the Y-axis direction.

In the second storage unit 42, when the feeders 25 are inserted into the respective second storage support portions 421, the plurality of feeders 25 are arranged side by side in the Y-axis direction.

[0036] In the example shown in FIG. 4, seven second storage support parts 421a to 421g are arranged in order from one end to the other end in the Y-axis direction in the second storage unit 42. Among the seven second storage support parts 421a to 421g, five second storage support parts 421a to 421e are support parts for supporting the feeders 25 respectively, and the second storage support parts 421f and 421g in a specific area 422 on the other end side in the Y-axis direction are support parts used when the management device 6 described later performs a support position change process. Note that FIG. 4 shows an example in which feeders 25H to 25K are respectively supported by the second storage support parts 421a to 421d. Insertion of the feeder 25 into each of the second storage support parts 421a to 421g in the second storage unit 42, and extraction of the feeder 25 from each of the second storage support parts 421a to 421g are performed by the replenishment device 5 described later in the production area AR1.

[0037] [Regarding the replenishment device] As shown in FIG. 1, the replenishment device 5 is a robot movable in the production area AR1 at each position facing each component mounter 2B, the first storage device 3, the first recovery device 30, the second storage device 4, and the second recovery device 40 in a plurality of mounting lines 2 respectively. The replenishment device 5 performs an operation of extracting the feeder 25 from each of the first storage support parts 321a to 321g of the first storage unit 32 and taking it into the interior in a state of moving to a position facing the first storage device 3. The replenishment device 5 performs an operation of inserting and extracting the feeder 25 with respect to each of the second storage support parts 421a to 421g of the second storage unit 42 in a state of moving to a position facing the second storage device 4. The replenishment device 5 performs an operation of extracting the feeder 25 to be recovered from the supply support part 24 that supports the feeder 25 to be recovered in each component supply unit 23 and recovering it into the interior in a state of moving to each position facing each component mounter 2B, and at the same time, performs an operation of inserting and replenishing the feeder 25 to be replenished with the replenished supply support part 24 as the replenishment destination. Further, the replenishment device 5 performs an operation of moving the feeder 25 to be recovered, which has been recovered into the interior, to the first recovery device 30 or the second recovery device 40 in a state of moving to a position facing the first recovery device 30 or the second recovery device 40.

[0038] The supply device 5 will be described with reference to FIG. 5. The supply device 5 includes a supply device main body 51, an operation unit 52, and a supply unit 53. The supply device main body 51 is a housing having an internal space in which the operation unit 52 and the supply unit 53 are arranged.

[0039] The supply unit 53 is a unit that supports a plurality of feeders 25 recovered from each component supply unit 23 of each component mounting machine 2B and supplies the feeders 25 to each component supply unit 23. The supply unit 53 has a plate-like shape extending in the X-axis direction and the Y-axis direction, and a plurality of supply support portions 531 are provided on its upper surface. The plurality of supply support portions 531 are constituted by rails extending in the X-axis direction and are arranged on the supply unit 53 so as to be aligned in the Y-axis direction. The plurality of supply support portions 531 support the feeder 25 that is exchanged between the supply support portion 24 of each component supply unit 23, the first storage support portion 321 of the first storage unit 32, and the second storage support portion 421 of the second storage unit 42 in an insertable and removable manner. In the supply unit 53, when the feeder 25 is inserted into each supply support portion 531, the plurality of feeders 25 are arranged side by side in the Y-axis direction. In the example shown in FIG. 5, six supply support portions 531a to 531f are arranged in order from one end to the other end in the Y-axis direction in the supply unit 53. The supply unit 53 is movable within a predetermined allowable movement range 532 in the Y-axis direction, which is the arrangement direction of the plurality of supply support portions 531a to 531f, within the supply device main body 51.

[0040] The operation unit 52 is a unit that performs an operation of moving the feeder 25 with respect to the replenishment unit 53. The operation unit 52 includes an arm part 54 and a hand part 55.

The hand part 55 moves in the Y-axis direction in the space above the replenishment unit 53 within the replenishment device main body 51 as the arm part 54 moves, and also moves in the X-axis direction with respect to the arm part 54. The hand part 55 moves the feeder 25 in the X-axis direction with respect to the arm part 54 while gripping the feeder 25 so that the feeder 25 is inserted into and removed from each of the replenishment support parts 531a to 531f on the replenishment unit 53.

[0041] When the replenishment device 5 is arranged at a position facing the first storage device 3, in a state where the replenishment unit 53 is arranged opposite to the first storage unit 32, the replenishment unit 53 moves in the Y-axis direction within a predetermined allowable movement range 532 so that the replenishment support part 531 at the replenishment source that supports the feeder 25 to be replenished faces the first storage support part 321 that supports the feeder 25 to be replenished to the component supply unit 23. The arm part 54 moves in the Y-axis direction so that the hand part 55 is positioned above the replenishment support part 531 at the replenishment source. Then, the hand part 55 moves from the first storage device 3 side to the replenishment device 5 side along the X-axis direction while gripping the feeder 25 to be replenished. In this case, the feeder 25 to be replenished moves so as to be withdrawn from the first storage support part 321 in the first storage unit 32 and is inserted into the replenishment support part 531 at the replenishment source on the replenishment unit 53.

[0042] Similarly, when the supply device 5 is arranged at a position facing the second storage device 4, in a state where the supply unit 53 is arranged to face the second storage unit 42, the supply unit 53 moves in the Y-axis direction within a predetermined allowable movement range 532 such that the supply support portion 531 at the supply source for supporting the feeder 25 to be supplied faces the second storage support portion 421 that supports the feeder 25 to be supplied. The arm portion 54 moves in the Y-axis direction such that the hand portion 55 is positioned above the supply support portion 531 at the supply source. Then, the hand portion 55 moves from the side of the second storage device 4 toward the side of the supply device 5 along the X-axis direction while gripping the feeder 25 to be supplied. In this case, the feeder 25 to be supplied moves so as to be withdrawn from the second storage support portion 421 in the second storage unit 42 and is inserted into the supply support portion 531 at the supply source on the supply unit 53.

[0043] When the supply device 5 is arranged at a position facing each component mounter 2B, in a state where the supply unit 53 is arranged to face each component supply unit 23, the supply unit 53 moves in the Y-axis direction within a predetermined allowable movement range 532 such that the supply support portion 531 at the collection destination for the feeder 25 to be collected from the component supply unit 23 to the supply unit 53 faces the supply support portion 24 at the collection source that supports the feeder 25 to be collected. The arm portion 54 moves in the Y-axis direction such that the hand portion 55 is positioned above the supply support portion 531 at the collection destination. Then, the hand portion 55 moves from the side of the component mounter 2B toward the side of the supply device 5 along the X-axis direction while gripping the feeder 25 to be collected. In this case, the feeder 25 to be collected moves so as to be withdrawn from the supply support portion 24 at the collection source in the component supply unit 23 and is inserted into the supply support portion 531 at the collection destination on the supply unit 53. As a result, the feeder 25 to be collected in the component supply unit 23 is collected onto the supply unit 53.

[0044] Further, the supply unit 53 moves in the Y-axis direction within a predetermined allowable movement range 532 such that the supply support portion 531 of the replenishment source that supported the feeder 25 to be replenished faces the supply support portion 24 that becomes the replenishment destination of the feeder 25 to be recovered in the component supply unit 23. The arm portion 54 moves in the Y-axis direction such that the hand portion 55 is positioned above the supply support portion 531 of the replenishment source. Then, the hand portion 55 moves from the side of the supply device 5 toward the side of the component mounter 2B along the X-axis direction while gripping the feeder 25 to be replenished. In this case, the feeder 25 to be replenished moves so as to be withdrawn from the supply support portion 531 of the replenishment source on the supply unit 53 and is inserted into the supply support portion 24 of the replenishment destination within the component supply unit 23. Thereby, the feeder 25 to be replenished on the supply unit 53 is replenished into the component supply unit 23 so as to be exchanged with the feeder 25 to be recovered.

[0045] [Regarding the management device] The management device 6 is configured by, for example, a microcomputer and is connected to each of the component mounter 2B, the first storage device 3, the second storage device 4, and the supply device 5 so as to be capable of data communication. The management device 6 is a device that manages the recovery of the feeder 25 to be recovered from each component supply unit 23 of each component mounter 2B and the replenishment of the feeder 25 to be replenished to each component supply unit 23.

[0046] As shown in the flowchart of FIG. 6, the management device 6 performs a production status recognition process S1, a list creation process S2, a setting process S3, a data generation process S4, a feeder arrangement process S5, a transfer process S7, a support position change process S8, and a temporary placement process S9.

[0047] [Production status recognition process] In the production status recognition process S1, the management device 6 acquires production status data D1 indicating the production status of the component mounting substrate by each component mounter 2B from each component mounter 2B. As shown in FIG. 7, the production status data D1 is data including serial number information D11, substrate name information D12, current production quantity information D13, supply support unit position information D14, feeder identification information D15, component identification information D16, component remaining quantity information D17, and remaining quantity threshold information D18. The serial number information D11 is information indicating the serial number of each component mounter 2B. The substrate name information D12 is information indicating the name of the substrate that is the current production target in each component mounter 2B. The current production quantity information D13 is information indicating the current production quantity of the substrate in each component mounter 2B. The supply support unit position information D14 is information indicating the position of the supply support unit 24 in the component supply unit 23 of each component mounter 2B. The feeder identification information D15 is information for identifying the type of the feeder 25 supported by the supply support unit 24 at the position indicated by the supply support unit position information D14. The component identification information D16 is information for identifying the type of the component supplied by the feeder 25 indicated by the feeder identification information D15. The component remaining quantity information D17 is information indicating the remaining quantity of the component indicated by the component identification information D16 in the feeder 25 indicated by the feeder identification information D15. The remaining quantity threshold information D18 is information indicating the threshold of the remaining quantity of the component for which a warning or the like should be notified before the component held in the feeder 25 indicated by the feeder identification information D15 runs out of components.

[0048] In the production status data D1 shown in FIG. 7, the feeder 25 of "F01" indicated by the feeder identification information D15, which is supported by the supply support unit 24a indicated by the supply support unit position information D14, is a tape feeder of the automatic loading type. The tape feeder of the automatic loading type can mount a plurality of reels around which a component storage tape containing components is wound. In the tape feeder of the automatic loading type, when the feeding of the component storage tape from the preceding reel around which the component storage tape for which component supply is performed first is wound is completed among the plurality of reels, the component storage tape is automatically fed from the succeeding reel around which the succeeding component storage tape is wound.

[0049] Also, in the production status data D1 shown in FIG. 7, for the supply support parts 24b, 24c, 24d indicated by the supply support part position information D14, the feeders 25 of "F02", "F03", "F04" indicated by the feeder identification information D15 are respectively supported. Each of the feeders 25 of "F02", "F03", "F04" supplies the parts of "P02" with the same part identification information D16. In this case, for example, when the feeder 25 of "F02" runs out of parts, the feeders 25 of "F03" and "F04" can supply the parts.

[0050] Also, in the production status data D1 shown in FIG. 7, the feeder identification information D15, the part identification information D16, the remaining part number information D17, and the remaining number threshold information D18 are not associated with the supply support part 24e indicated by the supply support part position information D14. In this case, the supply support part 24e indicated by the supply support part position information D14 is in a state of not supporting the feeder 25.

[0051] In the example shown in FIG. 7, the production status data D1 is data indicating the production status at the current time when the substrate of substrate name "B01" is produced in the production quantity "N01" by the component mounter 2B with the serial number "M01". And the production status data D1 is data indicating to what extent the remaining number of parts indicated by the remaining part number information D17 is with respect to the remaining number threshold indicated by the remaining number threshold information D18 for the feeders 25 supported by each of the supply support parts 24a to 24j arranged in the component supply unit 23 of the component mounter 2B with the serial number "M01". The management device 6 can recognize to what extent the remaining number of parts in the feeders 25 supported by each of the supply support parts 24a to 24j arranged in the component supply unit 23 is with respect to the remaining number threshold based on each production status data D1 corresponding to each component mounter 2B.

[0052] <List creation process> When the production status data D1 is acquired from each component mounting machine 2B, the management device 6 performs a list creation process S2. The list creation process S2 of the management device 6 will be described with reference to FIG. 8.

[0053] In the list creation process S2, based on each production status data D1 corresponding to each component mounting machine 2B, for each of the plurality of supply support parts 24a to 24j arranged in each component supply unit 23 of each component mounting machine 2B, the management device 6 calculates a predicted value of the time required until the remaining number of parts in the feeder 25 supported by each supply support part 24a to 24j reaches the remaining number threshold value. Then, based on the calculated predicted value, the management device 6 performs a process S21 of calculating a replenishment allowable time T1 indicating the allowable time until a new feeder 25 is replenished for each supply support part 24a to 24j.

[0054] Next, based on the replenishment allowable time T1 corresponding to each supply support part 24a to 24j in each component supply unit 23 of each component mounting machine 2B, the management device 6 performs a process S22 of recognizing the replenishment priority order of the feeder 25 for each supply support part 24a to 24j. At this time, in each supply support part 24a to 24j, the management device 6 recognizes the supply support part 24 with a higher replenishment priority order of the feeder 25 as the one with a shorter replenishment allowable time T1.

[0055] Next, the management device 6 determines, in each supply support unit 24a to 24j in each component supply unit 23 of each component mounter 2B, in order from the supply support unit 24 with the highest priority for replenishing the feeder 25 based on the replenishment allowable time T1, whether the feeder 25 can be replenished. At this time, for the supply support unit 24 that supports the tape feeder of the automatic loading method, the management device 6 determines that the feeder 25 can be replenished when the sending of the component storage tape from the preceding reel among the plurality of reels in the feeder 25 is completed and the sending of the component storage tape from the subsequent reel is in progress. In addition, when there are a plurality of supply support units 24 each supporting a plurality of feeders 25 capable of supplying the same type of component, the management device 6 determines that the supply support unit 24 supporting the feeder 25 whose remaining component count has reached the remaining count threshold can replenish the feeder 25. Further, for the supply support unit 24 that does not support the feeder 25, the management device 6 determines that the feeder 25 can be replenished when the supply of components from the supply support unit 24 is planned in the production plan of the component mounting substrate. Also, for the supply support unit 24 in which the supply of components of a type different from the current components is planned in the production plan of the component mounting substrate, the management device 6 determines that the feeder 25 can be replenished.

[0056] Then, the management device 6 performs a process S23 of specifying, in each supply support unit 24a to 24j in each component supply unit 23 of each component mounter 2B, in order from the supply support unit 24 with the highest priority for replenishing the feeder 25 based on the replenishment allowable time T1, the supply support unit 24 in a state where the feeder 25 can be replenished as the supply support unit 24 to which the replenishment of the feeder 25 to be replenished is requested as the replenishment destination.

[0057] Furthermore, based on each production status data D1 corresponding to each component mounter 2B, the management device 6 determines, for each supply support unit 24a to 24j in each component supply unit 23, that the supply support unit 24 that supports the feeder 25, which is not currently in need of replenishment but is assumed to have a high replenishment frequency, is to be transferred from the first storage unit 32 to the second storage unit 42, and identifies the supply support unit 24 as the replenishment destination of the transfer feeder 25. For example, the management device 6 recognizes the priority order of replenishment of the transfer feeder 25 using, as an index, the number of components supplied per unit time in the supply support unit 24. At this time, the management device 6 recognizes that the supply support unit 24 with a higher number of components supplied per unit time has a higher priority for replenishment of the transfer feeder 25. The management device 6, for each supply support unit 24a to 24j in each component supply unit 23, excluding the supply support unit 24 to which the feeder 25 to be replenished, which is specified in priority order based on the replenishment allowable time T1, is replenished, sequentially identifies the supply support unit 24 as the replenishment destination of the transfer feeder 25 starting from the supply support unit 24 with the largest number of components supplied per unit time. At this time, the management device 6 recognizes that the supply support unit 24 with a higher number of components supplied per unit time within a predetermined period from the current time has a higher priority for replenishment of the transfer feeder 25.

[0058] Note that the management device 6 may preferentially set, as the replenishment destination of the transfer feeder 25, the component supply unit 23 corresponding to the fourth to eighth mounting lines 2A4 to 2A8 belonging to the second specific mounting line 2 among the first to eighth mounting lines 2A1 to 2A8 as the plurality of mounting lines 2, the distance from the first storage device 3 of which is equal to or greater than a predetermined distance. That is, the management device 6 preferentially identifies, as the supply support unit 24 of the replenishment destination of the transfer feeder 25, the supply support unit 24 within the component supply unit 23 that supplies a large number of components per unit time within a predetermined period from the current time and corresponds to the second specific mounting line 2. Further, the management device 6 sets the priority order of replenishment of the transfer feeder 25 to be lower than the priority order of replenishment of the feeder 25 to be replenished.

[0059] Based on the production status data D1 corresponding to each component mounting machine 2B, when identifying the feeder 25 to be replenished and the supply support unit 24 at the replenishment destination corresponding to the transfer feeder 25, the management device 6 performs a process S24 of checking the location list L1 shown in FIG. 8. The location list L1 is data that shows, as a list, the feeders 25 supported by each of the first storage support parts 321a to 321g in the first storage unit 32 of the first storage device 3, each of the second storage support parts 421a to 421g in the second storage unit 42 of the second storage device 4, and each of the replenishment support parts 531a to 531f in the replenishment unit 53 of the replenishment device 5. The location list L1 shows the current support status of the feeder 25 in each support part of the first storage unit 32, the second storage unit 42, and the replenishment unit 53. The location list L1 includes key information DA, replenishment destination information DB, and possession information DC.

[0060] The key information DA indicates the basic information of each unit such as the first storage unit 32, the second storage unit 42, and the replenishment unit 53. The key information DA includes unit name information DA1 indicating the unit name of each unit and support part position information DA2 indicating the position of the support part in each unit. The possession information DC indicates information regarding the feeder 25 supported by the support part at the position indicated by the support part position information DA2 in the unit with the unit name indicated by the unit name information DA1. The possession information DC includes feeder identification information DC1 for identifying the type of the feeder 25 supported by each support part in each unit and part identification information DC2 for identifying the type of the parts supplied by the feeder 25. The replenishment destination information DB indicates information regarding the replenishment destination when replenishing the feeder 25 supported by the support part at the position indicated by the support part position information DA2 in the unit with the unit name indicated by the unit name information DA1. The replenishment destination information DB includes serial number information DB1 indicating the serial number of each component mounter 2B, supply support part position information DB2 indicating the position of the supply support part 24 in the component supply unit 23 of each component mounter 2B, feeder identification information DB3 for identifying the type of the feeder 25 supported by the supply support part 24 at the position indicated by the supply support part position information DB2, and part identification information DB4 for identifying the type of the parts supplied by the feeder 25 indicated by the feeder identification information DB3.

[0061] The location list L1 including the key information DA, the replenishment destination information DB, and the possession information DC indicates that the feeder 25 indicated by the possession information DC is currently supported by each support part in each unit such as the first storage unit 32, the second storage unit 42, and the replenishment unit 53 indicated by the key information DA. Further, the location list L1 indicates that the feeder 25 indicated by the possession information DC is replenished to the replenishment destination indicated by the replenishment destination information DB.

[0062] Based on the production status data D1, the management device 6 extracts, as feeders 25 scheduled to be stored in the first storage unit 32, the feeders 25 of the replenishment targets to be replenished to the supply support unit 24 of the replenishment destination and the transfer feeders 25 that are not registered in the location list L1 among the feeders 25. The management device 6 generates work instruction data D2 in the data generation process S4 described below so that the extracted feeders 25 are replenished to the first storage unit 32.

[0063] Based on the location list L1 and the above extraction result, the management device 6 performs a process S25 of specifying the storage source where the feeders 25 of the replenishment targets to be replenished to the supply support unit 24 of the replenishment destination and the transfer feeders 25 are stored, or the storage source scheduled to store them, in each component supply unit 23 of each component mounter 2B. Then, the management device 6 performs a process S26 of creating a replenishment preparation list LA in which the supply support unit 24 of the replenishment destination in each component supply unit 23 of each component mounter 2B is associated with the first storage support unit 321 and the second storage support unit 421 that support the feeders 25 of the replenishment targets and the transfer feeders 25 in the first storage unit 32 and the second storage unit 42.

[0064] As shown in FIG. 8, the replenishment preparation list LA is data that shows, as a list, the replenishment destination information DB, the storage source information DD, and the replenishment target information DE in association with each other. The replenishment destination information DB is information indicating the replenishment destinations of the feeders 25 to be replenished and the feeders 25 for transfer in each component supply unit 23 of each component mounter 2B. This replenishment destination information DB is associated with the priority order of replenishment of the feeders 25 to be replenished and the feeders 25 for transfer. Similar to the location list L1, the replenishment destination information DB includes serial number information DB1 indicating the serial number of each component mounter 2B, supply support unit position information DB2 indicating the position of the supply support unit 24 in the component supply unit 23 of each component mounter 2B, feeder identification information DB3 for identifying the type of feeder 25 supported by the supply support unit 24 at the position indicated by the supply support unit position information DB2, and component identification information DB4 for identifying the type of component supplied by the feeder 25 indicated by the feeder identification information DB3. The storage source information DD is information indicating the storage source where the feeders 25 to be replenished and the feeders 25 for transfer are stored, or the storage source where they are to be stored. The storage source information DD includes unit name information DD1 indicating the unit name where the feeders 25 to be replenished and the feeders 25 for transfer are stored, or are to be stored, in the first storage unit 32 and the second storage unit 42, and support unit position information DD2 indicating the position of the support unit that supports the feeders 25 to be replenished and the feeders 25 for transfer in the storage unit indicated by the unit name information DD1. The replenishment target information DE is information regarding the feeders 25 to be replenished and the feeders 25 for transfer. The replenishment target information DE includes feeder identification information DE1 for identifying the types of the feeders 25 to be replenished and the feeders 25 for transfer, and component identification information DE2 for identifying the types of components supplied by the feeders 25 to be replenished and the feeders 25 for transfer.

[0065] The replenishment preparation list LA in which the replenishment source information DB, the storage source information DD, and the replenishment target information DE are associated indicates that the feeder 25 to be replenished and the transfer feeder 25 indicated by the replenishment target information DE are stored in the storage source indicated by the storage source information DD and are to be replenished to the replenishment source indicated by the replenishment source information DB. In the replenishment preparation list LA shown in FIG. 8, the feeders 25 of "FA21", "FA22", and "FA23" indicated by the replenishment target information DE are respectively supported by the first storage support portions 321a, 321b, and 321c of the first storage unit 32 indicated by the storage source information DD, and are replenished to the supply support portions 24a, 24b, and 24c in the component supply unit 23 of the component mounter 2B with the serial number "M02" indicated by the replenishment source information DB. Further, in the replenishment preparation list LA shown in FIG. 8, the feeder 25 of "FA31" indicated by the replenishment target information DE is supported by the second storage support portion 421c of the second storage unit 42 indicated by the storage source information DD, and is replenished to the supply support portion 24c in the component supply unit 23 of the component mounter 2B with the serial number "M03" indicated by the replenishment source information DB. Note that, in the replenishment preparation list LA shown in FIG. 8, as the replenishment priority of the feeder 25, the first, second, and third priorities are respectively set for the supply support portions 24a, 24b, and 24c in the component supply unit 23 of the component mounter 2B with the serial number "M02" indicated by the replenishment source information DB, and the fourth priority is set for the supply support portion 24c in the component supply unit 23 of the component mounter 2B with the serial number "M03" indicated by the replenishment source information DB.

[0066] Based on the replenishment preparation list LA, the management device 6 can recognize the supply support portion 24 of the replenishment destination to which the feeder 25 to be replenished and the transfer feeder 25 should be replenished in each component supply unit 23 of each component mounter 2B in the plurality of mounting lines 2, together with the replenishment priority, and can recognize the first storage support portion 321 and the second storage support portion 421 that support the feeder 25 to be replenished and the transfer feeder 25 in the first storage unit 32 and the second storage unit 42.

[0067] <Setting process> When the supply preparation list LA is created, the management device 6 performs setting processing S3. The setting processing S3 of the management device 6 will be described with reference to FIGS. 9 and 10.

[0068] In the setting process S3, the management device 6 sets the supply support part 531 that is the recovery destination of the feeder 25 to be recovered from each component supply unit 23 of each component mounter 2B in the plurality of supply support parts 531a to 531f in the supply unit 53 of the supply device 5. In the example shown in FIGS. 9 and 10, the management device 6 sets the supply support part 531a in the supply unit 53 as the supply support part of the recovery destination. Also, in the setting process S3, based on the supply preparation list LA, the management device 6 sets the supply support part 531 that is the supply source for supporting the feeder 25 to be supplied in the plurality of supply support parts 531a to 531f in the supply unit 53 in association with the supply support part 24 at the supply destination in each component supply unit 23 of each component mounter 2B.

[0069] In the setting process S3, the management device 6 sets the supply support part 531 of the supply source in the supply unit 53 of the supply device 5 in the order of the priority of supply of the feeder 25 to be supplied in association with the supply support part 24 at the supply destination in each component supply unit 23 of each component mounter 2B. At this time, as shown in FIG. 9, the management device 6 assumes that the supply unit 53 moves within the allowable movement range 532 with respect to the component supply unit 23, recognizes the position range PR in which the supply support part 531 of the supply destination can face the supply support part 24 in the plurality of supply support parts 531a to 531f, and sets the supply support part 531 of the supply source based on the position range PR.

[0070] In the example shown in FIG. 9, the management device 6 recognizes, among the plurality of supply support parts 531a to 531f in the supply unit 53, the position range PR that can face the supply support part 24a of the supply destination of the feeder 25A to be replenished with the highest priority, and sets the supply support part 531b within the position range PR as the supply support part of the supply source that supports the feeder 25A. When there are a plurality of candidates within the position range PR as the supply support part 531 of the supply source that supports the feeder 25A, the management device 6 sets the supply support part 531 that is closer to the central position in the Y-axis direction within the position range PR as the supply support part 531 of the supply source. Similarly, the management device 6 recognizes, among the plurality of supply support parts 531a to 531f in the supply unit 53, the position range PR that can face the supply support part 24b of the supply destination of the feeder 25B to be replenished with the second highest priority, and sets the supply support part 531c within the position range PR as the supply support part of the supply source that supports the feeder 25B. Further, the management device 6 recognizes, among the plurality of supply support parts 531a to 531f in the supply unit 53, the position range PR that can face the supply support part 24c of the supply destination of the feeder 25C to be replenished with the third highest priority, and sets the supply support part 531d within the position range PR as the supply support part of the supply source that supports the feeder 25C.

[0071] Based on the setting result of the setting process S3, the management device 6 can recognize the supply support part 531a of the collection destination that is the collection destination of the feeder 25 to be collected in the supply unit 53 of the supply device 5. Further, based on the setting result of the setting process S3, the management device 6 associates the supply support parts 24a, 24b, 24c of the supply destinations to supply the feeders 25A, 25B, 25C to be replenished in the component supply unit 23, and can recognize the supply support parts 531b, 531c, 531d of the supply sources that support the feeders 25A, 25B, 25C to be replenished in the supply unit 53 of the supply device 5.

[0072] When the replenishment support unit 531 of the replenishment source in the replenishment unit 53 of the replenishment device 5 is set in the order of the priority of replenishment of the feeder 25 to be replenished, as shown in FIG. 10, as the priority becomes lower, a situation where the replenishment support unit 531 of the replenishment source cannot be set within the position range PR appears. In the example shown in FIG. 10, among the plurality of replenishment support units 531a to 531f in the replenishment unit 53, the replenishment support units 531b, 531c, 531d within the position range PR that can face the supply support unit 24c of the replenishment destination of the feeder 25K whose priority is the fourth are set as the replenishment support units of the replenishment sources that support the feeders 25A, 25B, 25C. In this case, the replenishment support unit 531 of the replenishment source that supports the feeder 25K cannot be set within the position range PR. In this case, the management device 6 sets the replenishment support unit 531e outside the position range PR with respect to the supply support unit 24c of the replenishment destination as the replenishment support unit of the replenishment source that supports the feeder 25K, and adds out-of-range information J1 to the replenishment support unit 531e of the replenishment source.

[0073] When the setting of the replenishment support units 531b, 531c, 531d, 531e of the replenishment sources that support the feeders 25A, 25B, 25C, 25K to be replenished is completed, the management device 6 determines whether there are any remaining replenishment support units among the plurality of replenishment support units 531a to 531f in the replenishment unit 53, excluding the replenishment support unit 531a of the collection destination and the replenishment support units 531b, 531c, 531d, 531e of the replenishment sources. When the number of feeders 25A, 25B, 25C, 25K to be replenished is less than the number of replenishment support units 531a to 531f in the replenishment unit 53, there will be remaining replenishment support units. In the example shown in FIG. 10, the replenishment support unit 531f in the replenishment unit 53 becomes the remaining replenishment support unit. In this case, the management device 6 sets the remaining replenishment support unit 531f in the replenishment unit 53 as the transfer support unit that supports the transfer feeder 25E.

[0074] <Data generation process> As shown in FIG. 6, when the replenishment preparation list LA is created in the list creation process S2 and the setting for each replenishment support unit 531 in the replenishment unit 53 is completed in the setting process S3, the management device 6 performs a data generation process S4 for generating the work instruction data D2 and the control data D3.

[0075] The work instruction data D2 is data for instructing the work of replenishing the feeder 25 that is not registered in the location list L1 among the feeders 25 to be replenished to the supply support unit 24 at the replenishment destination specified based on the production status data D1 and the feeder 25 for transfer to the first storage unit 32 of the first storage device 3. An operator or a work robot performs the work of preparing the replenishment feeder 25 in the preparation area AR2 based on the work instruction data D2, and performs the work of inserting the prepared replenishment feeder 25 into a predetermined first storage support unit 321 in the first storage unit 32. When the feeder 25 is inserted into the first storage support unit 321 in the first storage unit 32, the information regarding the first storage support unit 321 is recorded in the location list L1. That is, the location list L1 is updated each time the feeder 25 is inserted into the first storage support unit 321 of the first storage unit 32 based on the work instruction data D2.

[0076] The control data D3 is data related to the control of the replenishment device 5. The management device 6 controls the replenishment device 5 based on the control data D3, and performs an exchange process S6 including a feeder arrangement process S5, a recovery process S61, and a replenishment process S62, a transfer process S7, a support position change process S8, and a temporary placement process S9 described later. The control data D3 includes movement path data D31 shown in FIG. 11. The movement path data D31 is data indicating the movement path when the replenishment device 5 moves within the production area AR1. The movement path of the replenishment device 5 includes a first path RT1, a second path RT2, and a third path RT3. The first path RT1 indicates the path along which the replenishment device 5 moves between the position facing the first storage device 3 and the first recovery device 30 and the position facing each component mounter 2B on the first to eighth mounting lines 2A1 to 2A8. The second path RT2 indicates the path along which the replenishment device 5 moves between the position facing the second storage device 4 and the second recovery device 40 and the position facing each component mounter 2B on the first to eighth mounting lines 2A1 to 2A8. The third path RT3 indicates the path along which the replenishment device 5 moves between the position facing the first storage device 3 and the first recovery device 30 and the position facing the second storage device 4 and the second recovery device 40 via the position facing each component mounter 2B on the first to eighth mounting lines 2A1 to 2A8.

[0077] For each of the first to eighth mounting lines 2A1 to 2A8, the management device 6 selects a movement route of the supply device 5 in the production area AR1 based on the required supply quantity and the supply capacity of the supply device 5, and generates control data D3 including movement route data D31 indicating the selected movement route. The required supply quantity indicates, for each of the first to eighth mounting lines 2A1 to 2A8, the total number of supply support parts 24 of the replenishment destinations where replenishment of the feeders 25 is required in each component supply unit 23 of each component mounter 2B. The management device 6 recognizes the required supply quantity based on the number of supply support parts 24 of the replenishment destinations of the feeders 25 to be replenished included in the supply preparation list LA. The supply capacity of the supply device 5 indicates, for each of the first to eighth mounting lines 2A1 to 2A8, the total number of feeders 25 that can be replenished by the supply device 5 within a predetermined supply allowable time T1. The management device 6 sets the supply capacity of the supply device 5 in consideration of the movement time of the supply device 5 along the movement route. That is, the management device 6 sets the supply capacity of the supply device 5 for each of the first route RT1, the second route RT2, and the third route RT3 as the movement route of the supply device 5.

[0078] In the first to eighth mounting lines 2A1 to 2A8, for the first specific mounting line 2 with a separation distance from the first storage device 3 less than a predetermined distance and the second specific mounting line 2 with a separation distance from the first storage device 3 greater than or equal to the predetermined distance, the supply capacity for each movement route of the supply device 5 is different. For example, as shown in FIG. 11, in the first mounting line 2A1 belonging to the first specific mounting line 2 and having the shortest separation distance from the first storage device 3, the supply capacity corresponding to the first route RT1 and the supply capacity corresponding to the second route RT2 are substantially the same value, and the supply capacity corresponding to the third route RT3 is smaller than the supply capacity corresponding to the first route RT1 and the second route RT2. On the other hand, in the eighth mounting line 2A8 belonging to the second specific mounting line 2 and having the longest separation distance from the first storage device 3 and being close to the second storage device 4, the supply capacity corresponding to the second route RT2 is larger than the supply capacity corresponding to the first route RT1, and the supply capacity corresponding to the third route RT3 is smaller than the supply capacity corresponding to the first route RT1.

[0079] When the replenishment required quantity is greater than or equal to the replenishable quantity corresponding to the third route RT3, the management device 6 selects the first route RT1 or the second route RT2 as the movement route of the replenishment device 5 based on the magnitude relationship between the replenishable quantity corresponding to the first route RT1 and the replenishable quantity corresponding to the second route RT2, and generates control data D3 including movement route data D31 indicating the selected movement route. On the other hand, when the replenishment required quantity is less than the replenishable quantity corresponding to the third route RT3, the management device 6 selects the third route RT3 as the movement route of the replenishment device 5, and generates control data D3 including movement route data D31 indicating the selected third route RT3.

[0080] Specifically, when the replenishment required quantity at the current time of the first specific mounting line 2 (for example, the first mounting line 2A1) is less than the replenishable quantity corresponding to the third route RT3, the management device 6 selects the third route RT3 as the movement route of the replenishment device 5 corresponding to the first specific mounting line 2. In this case, the number of replenishment support parts 531 in the replenishment source within the replenishment unit 53 that supports the feeder 25 to be replenished, which is set corresponding to the first specific mounting line 2 based on the replenishment preparation list LA in the setting process S3, is consistent with the replenishment required quantity of the first specific mounting line 2 at the current time. And when the third route RT3 is selected corresponding to the first specific mounting line 2, the management device 6 sets the replenishment support part 531 that supports the feeder 25 for transfer in the replenishment unit 53 in the setting process S3. Thereby, assuming that in the future time point after the current time, the replenishment required quantity of the second specific mounting line 2 (for example, the eighth mounting line 2A8) becomes larger than the replenishable quantity corresponding to the first route RT1, the feeder 25 for transfer can be pre-transferred from the first storage unit 32 to the second storage unit 42. In this case, when the replenishment required quantity of the second specific mounting line 2 becomes larger than the replenishable quantity corresponding to the first route RT1, the management device 6 selects the second route RT2 as the movement route of the replenishment device 5 corresponding to the second specific mounting line 2. Thereby, the feeder 25 for transfer pre-transferred to the second storage unit 42 can be replenished to each component supply unit 23 of each component mounting machine 2B in the second specific mounting line 2.

[0081] <Feeder Arrangement Process> When generating the control data D3, the management device 6 controls the replenishment device 5 based on the control data D3 and performs the feeder arrangement process S5. The feeder arrangement process S5 of the management device 6 will be described with reference to FIGS. 12 and 13.

[0082] When the movement path data D31 included in the control data D3 indicates the first path RT1 and the third path RT3, as shown in FIG. 12, the management device 6 controls the replenishment device 5 and moves the replenishment device 5 so that the replenishment unit 53 is disposed at a position facing the first storage unit 32 of the first storage device 3. With the replenishment unit 53 disposed at a position facing the first storage unit 32, the management device 6 moves the replenishment target feeders 25A, 25B, 25C supported by the first storage support portions 321a, 321b, 321c of the first storage unit 32 so that they are disposed at the replenishment source replenishment support portions 531b, 531c, 531d in the replenishment unit 53, and moves the replenishment unit 53 within the allowable movement range 532 and operates the operation unit 52 including the arm portion 54 and the hand portion 55. Further, the management device 6 moves the transfer feeder 25E supported by the first storage support portion 321e of the first storage unit 32 so that it is disposed at the replenishment support portion 531f as the transfer support portion in the replenishment unit 53, and moves the replenishment unit 53 within the allowable movement range 532 and operates the operation unit 52 including the arm portion 54 and the hand portion 55.

[0083] Specifically, the management device 6 performs a first arrangement movement process of moving the supply unit 53 within the allowable movement range 532 so that the supply support parts 531b, 531c, 531d of the supply source face the first storage support parts 321a, 321b, 321c that support the feeders 25A, 25B, 25C to be supplied. Then, the management device 6 moves the arm part 54 so that the hand part 55 is positioned above the supply support parts 531b, 531c, 531d of the supply source, and then performs a second arrangement movement process of moving the hand part 55 holding the feeders 25A, 25B, 25C to be supplied from the first storage device 3 side to the supply device 5 side. As a result, the feeders 25A, 25B, 25C to be supplied move so as to be withdrawn from the first storage support parts 321a, 321b, 321c in the first storage unit 32 and are inserted into the supply support parts 531b, 531c, 531d of the supply source on the supply unit 53.

[0084] Also, in the first arrangement movement process, the management device 6 moves the supply unit 53 within the allowable movement range 532 so that the supply support part 531f as a transfer support part faces the first storage support part 321e that supports the transfer feeder 25E. Then, in the second arrangement movement process, the management device 6 moves the arm part 54 so that the hand part 55 is positioned above the supply support part 531f as a transfer support part, and then moves the hand part 55 holding the transfer feeder 25E from the first storage device 3 side to the supply device 5 side. As a result, the transfer feeder 25E moves so as to be withdrawn from the first storage support part 321e in the first storage unit 32 and is inserted into the supply support part 531f on the supply unit 53.

[0085] When the movement path data D31 included in the control data D3 indicates the second path RT2, as shown in FIG. 13, the management device 6 controls the replenishment device 5 and moves the replenishment device 5 so that the replenishment unit 53 is disposed at a position facing the second storage unit 42 of the second storage device 4. With the replenishment unit 53 disposed at a position facing the second storage unit 42, the management device 6 allows the replenishment unit 53 to move within the allowable movement range 532 and operates the operation unit 52 including the arm unit 54 and the hand unit 55 so that the feeder 25K to be replenished supported by the second storage support portion 421d of the second storage unit 42 moves and is disposed on the replenishment support portion 531e of the replenishment source in the replenishment unit 53.

[0086] Specifically, the management device 6 performs a first arrangement movement process of moving the replenishment unit 53 within the allowable movement range 532 so that the replenishment support portion 531e of the replenishment source faces the second storage support portion 421d that supports the feeder 25K to be replenished. Then, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the replenishment support portion 531e of the replenishment source, and then performs a second arrangement movement process of moving the hand unit 55 holding the feeder 25K to be replenished from the second storage device 4 side to the replenishment device 5 side. As a result, the feeder 25K to be replenished moves so as to be extracted from the second storage support portion 421d in the second storage unit 42 and is inserted into the replenishment support portion 531e of the replenishment source on the replenishment unit 53.

[0087] <Replacement process> In the supply unit 53 of the supply device 5, a supply support part 531a of the collection destination for the feeder 25 to be collected is set. When the feeders 25 are arranged in the supply support parts 531b to 531f, the management device 6 performs an exchange process S6 including a collection process S61 and a supply process S62. When performing the exchange process S6, the management device 6 controls the supply device 5 and moves the supply device 5 so that the supply unit 53 is arranged at a position facing the component supply unit 23 of the component mounter 2B. When the movement path data D31 included in the control data D3 indicates the first path RT1 and the third path RT3, the management device 6 moves the supply device 5 from a position facing the first storage unit 32 of the first storage device 3 to a position facing the component supply unit 23 of the component mounter 2B. On the other hand, when the movement path data D31 included in the control data D3 indicates the second path RT2, the management device 6 moves the supply device 5 from a position facing the second storage unit 42 of the second storage device 4 to a position facing the component supply unit 23 of the component mounter 2B. The exchange process S6 of the management device 6 will be described with reference to FIGS. 14 and 15.

[0088] As shown in FIG. 14, the management device 6 performs a collection process S61 of moving the supply unit 53, the arm unit 54, and the hand unit 55 so that the feeders 25A, 25B, and 25C to be collected, which are supported by the supply support parts 24a, 24b, and 24c of the collection source in the component supply unit 23, move and are collected by the supply unit 53. Also, as shown in FIG. 15, the management device 6 moves the supply unit 53, the arm unit 54, and the hand unit 55 so that the feeders 25A, 25B, and 25C to be supplied, which are supported by the supply support parts 531b, 531c, and 531d of the supply source in the supply unit 53, move to the supply support parts 24a, 24b, and 24c of the supply destination after the feeders 25A, 25B, and 25C to be collected are extracted in the component supply unit 23, and performs a supply process S62. At this time, the management device 6 performs the collection process S61 and the supply process S62 so that the feeders 25A, 25B, and 25C to be supplied are supplied to the component supply unit 23 in response to the collection of the feeders 25A, 25B, and 25C to be collected according to the supply priority indicated by the supply preparation list LA.

[0089] Specifically, in the recovery process S61, the management device 6 performs a first recovery movement process and a second recovery movement process. In the first recovery movement process, the management device 6 moves the supply unit 53 within the allowable movement range 532 so that the supply support unit 531a at the recovery destination faces the supply support unit 24a at the recovery source that supports the feeder 25A to be recovered corresponding to the feeder 25A to be replenished with the highest replenishment priority. Next, in the second recovery movement process, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the supply support unit 531a at the recovery destination. Then, the management device 6 moves the hand unit 55 holding the feeder 25A to be recovered from the component mounter 2B side to the supply device 5 side. As a result, the feeder 25A to be recovered moves so as to be withdrawn from the supply support unit 24a at the recovery source in the component supply unit 23 and is recovered by the supply support unit 531a at the recovery destination on the supply unit 53.

[0090] When the feeder 25A to be recovered is recovered by the supply support unit 531a at the recovery destination, the management device 6 performs a replenishment process S62. In the replenishment process S62, the management device 6 performs a first replenishment movement process and a second replenishment movement process. In the first replenishment movement process, the management device 6 moves the supply unit 53 within the allowable movement range 532 so that the supply support unit 531b at the replenishment source that supports the feeder 25A to be replenished with the highest replenishment priority faces the supply support unit 24a at the replenishment destination. Next, in the second replenishment movement process, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the supply support unit 531b at the replenishment source. Then, the management device 6 moves the hand unit 55 holding the feeder 25A to be replenished from the supply device 5 side to the component mounter 2B side. As a result, the feeder 25A to be replenished moves so as to be withdrawn from the supply support unit 531b at the replenishment source on the supply unit 53 and is replenished to the supply support unit 24a at the replenishment destination in the component supply unit 23.

[0091] When the feeder 25A to be replenished is replenished to the supply support part 24a of the replenishment destination, the replenishment support part 531b in the replenishment unit 53 becomes an empty state where the feeder 25 is not supported. In this case, the management device 6 performs a recovery process S61 of the feeder 25B to be recovered corresponding to the feeder 25B to be replenished with the second highest replenishment priority, with the empty replenishment support part 531b as the recovery destination. As a result, the feeder 25B to be recovered moves so as to be withdrawn from the supply support part 24b of the recovery source in the component supply unit 23 and is recovered to the empty replenishment support part 531b that becomes the recovery destination on the replenishment unit 53. When the feeder 25B to be recovered is recovered to the replenishment support part 531b, the management device 6 performs a replenishment process S62 of the feeder 25B to be replenished with the second highest replenishment priority. As a result, the feeder 25B to be replenished moves so as to be withdrawn from the replenishment support part 531c of the replenishment source on the replenishment unit 53 and is replenished to the supply support part 24b of the replenishment destination in the component supply unit 23.

[0092] When the feeder 25B to be replenished is replenished to the supply support part 24b of the replenishment destination, the replenishment support part 531c in the replenishment unit 53 becomes an empty state where the feeder 25 is not supported. In this case, the management device 6 performs a recovery process S61 of the feeder 25C to be recovered corresponding to the feeder 25BC to be replenished with the third highest replenishment priority, with the empty replenishment support part 531c as the recovery destination. As a result, the feeder 25C to be recovered moves so as to be withdrawn from the supply support part 24c of the recovery source in the component supply unit 23 and is recovered to the empty replenishment support part 531c that becomes the recovery destination on the replenishment unit 53. When the feeder 25C to be recovered is recovered to the replenishment support part 531c, the management device 6 performs a replenishment process S62 of the feeder 25C to be replenished with the third highest replenishment priority. As a result, the feeder 25C to be replenished moves so as to be withdrawn from the replenishment support part 531d of the replenishment source on the replenishment unit 53 and is replenished to the supply support part 24c of the replenishment destination in the component supply unit 23.

[0093] As described above, when the management device 6 performs the replacement process S6 including the feeder arrangement process S5, the recovery process S61, and the supply process S62 based on the required supply quantity and the supplyable quantity of the supply device 5, the management device 6 can select a plurality of movement paths including the first path RT1, the second path RT2, and the third path RT3 as the movement path of the supply device 5. That is, when the supply device 5 supplies the feeder 25 to be supplied to each component supply unit 23 of each component mounter 2B, the degree of freedom in selecting the movement path of the supply device 5 can be increased. Thereby, it becomes possible to improve the supply efficiency of the feeder 25 to each component supply unit 23 of each component mounter 2B in the first to eighth mounting lines 2A1 to 2A8 as a plurality of mounting lines 2.

[0094] <Transfer process> When the movement path data D31 included in the control data D3 indicates the third path RT3 and the transfer feeder 25E is arranged on the supply support portion 531f as the transfer support portion of the supply unit 53 in the feeder arrangement process S5, the management device 6 performs the transfer process S7. The transfer process S7 of the management device 6 will be described with reference to FIG. 16.

[0095] With the transfer feeder 25E arranged on the supply support portion 531f as the transfer support portion of the supply unit 53, the management device 6 moves the supply device 5 so that the supply unit 53 is arranged at a position facing the second storage unit 42 of the second storage device 4. With the supply unit 53 arranged at a position facing the second storage unit 42, the management device 6 moves the supply unit 53, the arm unit 54, and the hand unit 55 so that the transfer feeder 25E supported by the supply support portion 531f of the supply unit 53 moves and is supported by the second storage support portion 421e at a predetermined position in the second storage unit 42, and performs the transfer process S7.

[0096] Specifically, in the transfer process S7, the management device 6 performs a first transfer movement process and a second transfer movement process. In the first transfer movement process, the management device 6 moves the replenishment unit 53 within the allowable movement range 532 so that the replenishment support unit 531f supporting the transfer feeder 25E faces the second storage support unit 421e at the transfer destination. Next, in the second transfer movement process, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the replenishment support unit 531f. Then, the management device 6 moves the hand unit 55 holding the transfer feeder 25E from the replenishment device 5 side to the second storage device 4 side. As a result, the transfer feeder 25E moves so as to be withdrawn from the replenishment support unit 531f on the replenishment unit 53 and is transferred to the second storage support unit 421e at the transfer destination within the second storage unit 42. Thereby, when the number of replenishment requests is smaller than the number of replenishable units corresponding to the third route RT3 and the movement route data D31 included in the control data D3 indicates the third route RT3, the feeder 25E stored in the first storage unit 32 of the first storage device 3 can be used as the transfer feeder 25E and replenished to the second storage unit 42 of the second storage device 4.

[0097] As described above, the first to eighth mounting lines 2A1 to 2A8 as the plurality of mounting lines 2 are installed such that the distances from the first storage device 3 are different. Further, the second storage device 4 is installed at a position closer to the first storage device 3 than the first storage device 3 with respect to the fourth to eighth mounting lines 2A4 to 2A8 belonging to the second specific mounting line 2 whose distance from the first storage device 3 is a predetermined distance or more. In this case, when replenishing the feeder 25 to be replenished to the component supply unit 23 corresponding to the fourth to eighth mounting lines 2A4 to 2A8 by the replenishment device 5, selecting the second route RT2 rather than the first route RT1 as the movement route of the replenishment device 5 can shorten the movement distance of the replenishment device 5. Thereby, it becomes possible to improve the replenishment efficiency of the feeder 25 to the component supply unit 23 corresponding to the fourth to eighth mounting lines 2A4 to 2A8.

[0098] In this case, among the plurality of feeders 25 stored in the second storage unit 42, the feeders 25 replenished to the component supply units 23 corresponding to the fourth to eighth mounting lines 2A4 to 2A8 are frequently taken out from the second storage unit 42. Therefore, in the setting process S3, when the management device 6 sets a transfer support unit that supports the feeder 25 for transfer from the first storage unit 32 to the second storage unit 42, the component supply units 23 corresponding to the fourth to eighth mounting lines 2A4 to 2A8 are preferentially set as the replenishment destinations of the transfer feeder 25. Thereby, the feeder 25 replenished to the component supply units 23 corresponding to the fourth to eighth mounting lines 2A4 to 2A8 can be transferred from the first storage unit 32 to the second storage unit 42 as the transfer feeder 25 and replenished to the second storage unit 42.

[0099] <Support position change process> As shown in FIG. 10 above, when the management device 6 sets the supply support unit 531e outside the position range PR as the supply support unit of the supply source for the supply support unit 24c of the replenishment destination, the management device 6 adds the out-of-range information J1 to the supply support unit 531e of the supply source. Even if the supply unit 53 moves within the allowable movement range 532 with respect to the component supply unit 23, the supply support unit 531e of the supply source with the out-of-range information J1 added thereto is not arranged at a position facing the supply support unit 24c of the replenishment destination. In this case, the feeder 25K to be replenished supported by the supply support unit 531e of the supply source with the out-of-range information J1 added thereto in the supply unit 53 cannot be replenished to the supply support unit 24c of the replenishment destination in the component supply unit 23.

[0100] Therefore, the management device 6 performs a support position change process S8 shown in FIGS. 17 and 18. In the support position change process S8, with the feeder 25K to be replenished supported by the replenishment support unit 531e of the replenishment source with the out-of-range information J1 added, the management device 6 moves the replenishment device 5 so that the replenishment unit 53 is disposed at a position facing the second storage unit 42. Then, the management device 6 moves the replenishment unit 53, the arm unit 54, and the hand unit 55 so that the feeder 25K to be replenished moves to the replenishment support unit 531d within the position range PR via the second storage unit 42.

[0101] Specifically, in the support position change process S8, the management device 6 performs a first change movement process, a second change movement process, a third change movement process, and a fourth change movement process.

[0102] In the first change movement process, the management device 6 moves the replenishment unit 53 within the allowable movement range 532 so that the replenishment support unit 531e of the replenishment source with the out-of-range information J1 added faces the second storage support unit 421f within the specific area 422 in the second storage unit 42. Next, in the second change movement process, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the replenishment support unit 531e of the replenishment source with the out-of-range information J1 added. Then, the management device 6 moves the hand unit 55 holding the feeder 25K to be replenished from the side of the replenishment device 5 to the side of the second storage device 4. As a result, the feeder 25K to be replenished moves so as to be withdrawn from the replenishment support unit 531e on the replenishment unit 53 and is supported by the second storage support unit 421f within the second storage unit 42.

[0103] Next, in the third change movement process, the management device 6 moves the replenishment unit 53 within the allowable movement range 532 so that the replenishment support unit 531d within the position range PR in the replenishment unit 53 faces the second storage support unit 421f that supports the feeder 25K to be replenished in the supply support unit 24c at the replenishment destination. Next, in the fourth change movement process, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the replenishment support unit 531d within the position range PR. Then, the management device 6 moves the hand unit 55 holding the feeder 25K to be replenished from the side of the second storage device 4 to the side of the replenishment device 5.

[0104] As a result, in the replenishment unit 53 of the replenishment device 5, the feeder 25K to be replenished, which was supported by the replenishment support unit 531e of the replenishment source with the out-of-range information J1 added, can be moved via the second storage unit 42 to the replenishment support unit 531d within the position range PR that can face the supply support unit 24c at the replenishment destination. Then, the feeder 25K to be replenished, which has been moved to the replenishment support unit 531d within the position range PR, can be replenished to the supply support unit 24c at the replenishment destination in the component supply unit 23.

[0105] <Temporary placement process> As shown in FIG. 19, in the first to eighth mounting lines 2A1 to 2A8 as a plurality of mounting lines 2, there may be a case where the non-permission information J2 that disallows replenishment of the feeder 25K to be replenished to the component supply unit 23 is output from the component mounter 2B. When the management device 6 acquires the non-permission information J2 in a state where the replenishment device 5 has moved to a position facing the component supply unit 23, the management device 6 moves the replenishment device 5 to a position facing the second storage unit 42 and performs the temporary placement process S9.

[0106] In the temporary placement process S9, the management device 6 moves the replenishment unit 53, the arm unit 54, and the hand unit 55 so that the feeder 25K to be replenished corresponding to the non-permission information J2 moves from the replenishment unit 53 to the second storage unit 42.

[0107] Specifically, the management device 6 moves the replenishment unit 53 within the allowable movement range 532 so that the replenishment support unit 531d that supports the feeder 25K to be replenished corresponding to the non-permission information J2 faces the second storage support unit 421d at a predetermined position in the second storage unit 42. Next, the management device 6 moves the arm unit 54 so that the hand unit 55 is positioned above the replenishment support unit 531d. Then, the management device 6 moves the hand unit 55 in the state of gripping the feeder 25K to be replenished from the replenishment device 5 side to the second storage device 4 side. As a result, the feeder 25K to be replenished corresponding to the non-permission information J2 can be temporarily placed in the second storage unit 42.

[0108] Note that the above-described specific embodiments mainly include inventions having the following configurations.

[0109] A component mounting system according to one aspect of the present invention includes a component mounter having a component supply unit that supports a plurality of feeders for supplying components to be mounted on a substrate, a plurality of mounting lines installed in a predetermined production area, a first storage unit installed in a preparation area adjacent to the production area for storing a plurality of the feeders, a second storage unit installed at a position spaced apart from the plurality of mounting lines in the production area for storing a plurality of the feeders, a replenishment unit that is movable within the production area to positions respectively facing each of the component supply units of the plurality of mounting lines, the first storage unit, and the second storage unit, and that supports a plurality of the feeders to be replenished to each of the component supply units, and an operation unit that performs an operation of moving the feeders with respect to the replenishment unit. The component mounting system further includes a management device that manages replenishment of the feeders to be replenished to each of the component supply units. The management device controls the replenishment device and performs a feeder arrangement process of operating the operation unit so that the feeders to be replenished stored in the first storage unit or the second storage unit move to the replenishment unit and are arranged therein with the replenishment device moved to positions respectively facing the first storage unit or the second storage unit, and a replenishment process of operating the operation unit so that the feeders to be replenished arranged in the replenishment unit move to and are replenished to each of the component supply units with the replenishment device moved to positions respectively facing each of the component supply units.

[0110] According to this component mounting system, the feeders replenished to the respective component supply units of the component mounters on the plurality of mounting lines installed in the production area are stored in a first storage unit installed in a preparation area adjacent to the production area, and are also stored in a second storage unit installed at a position separated from the plurality of mounting lines in the production area. Further, in the production area, a replenishment device capable of freely moving within the production area is arranged. This replenishment device includes a replenishment unit that supports a plurality of feeders to be replenished to the respective component supply units, and an operation unit that performs an operation of moving the feeders with respect to the replenishment unit. Then, the management device controls the replenishment device to perform a feeder placement process and a replenishment process, whereby the feeders are replenished to the respective component supply units of the component mounters.

[0111] In the feeder placement process, the management device operates the operation unit so that the feeder to be replenished stored in the first storage unit or the second storage unit moves and is arranged in the replenishment unit with the replenishment device moved to each position facing the first storage unit or the second storage unit. As a result, the feeder to be replenished to the respective component supply units of the component mounters moves from the first storage unit or the second storage unit to the replenishment unit of the replenishment device and is arranged in the replenishment unit. On the other hand, in the replenishment process, the management device operates the operation unit so that the feeder to be replenished arranged in the replenishment unit moves and is replenished to the respective component supply units with the replenishment device moved to the position facing the respective component supply units. As a result, the feeders to be replenished are replenished to the respective component supply units of the component mounters.

[0112] When the management device performs the feeder arrangement process and the replenishment process, as the movement path of the replenishment device, it can select a plurality of movement paths including a path for moving the replenishment device between each component supply unit of each component mounter and the first storage unit, and a path for moving the replenishment device between each component supply unit and the second storage unit. That is, when replenishing the feeder to be replenished to each component supply unit by the replenishment device, the degree of freedom in selecting the movement path of the replenishment device can be increased. Thereby, it becomes possible to improve the replenishment efficiency of the feeder to each component supply unit of each component mounter in a plurality of mounting lines.

[0113] In the above component mounting system, each of the component supply units may have a plurality of supply support portions arranged in a predetermined direction and supporting the feeder, and the replenishment unit may have a plurality of replenishment support portions arranged in a predetermined direction and supporting the feeder. In this case, as a pre-process of the feeder arrangement process and the replenishment process, the management device determines a supply support portion of the replenishment destination where replenishment of the feeder to be replenished is requested among the plurality of supply support portions in each component supply unit, and the first storage unit and the second storage unit. A list creation process for creating a replenishment preparation list associating the storage unit storing the feeder to be replenished, and based on the replenishment preparation list, a replenishment source replenishment support portion for supporting the feeder to be replenished among the plurality of replenishment support portions in the replenishment unit is set in association with the supply support portion of the replenishment destination in each component supply unit. And a setting process.

[0114] In this mode, the management device performs a list creation process and a setting process as pre - processing for the feeder arrangement process and the replenishment process. In the list creation process, the management device creates a replenishment preparation list in which the supply support section of the replenishment destination where replenishment of the feeder to be replenished is requested in each component supply unit of each component mounter is associated with the storage unit that stores the feeder to be replenished in the first storage unit and the second storage unit. Based on the replenishment preparation list, the management device can recognize the supply support section of the replenishment destination where the feeder to be replenished should be replenished in each component supply unit, and can also recognize the storage unit of the storage source that stores the feeder to be replenished in the first storage unit and the second storage unit.

[0115] On the other hand, in the setting process, the management device, based on the replenishment preparation list, associates and sets the supply support section of the replenishment source that supports the feeder to be replenished in the replenishment unit of the replenishment device with the supply support section of the replenishment destination within each component supply unit. Based on the setting result of the setting process, the management device can recognize the supply support section of the replenishment source that supports the feeder to be replenished in the replenishment unit of the replenishment device in association with the supply support section of the replenishment destination where the feeder to be replenished should be replenished in each component supply unit.

[0116] In the above-described component mounting system, when the number of feeders to be replenished is less than the number of replenishment support parts in the replenishment unit, in the setting process, the management device may set the remaining replenishment support parts excluding the replenishment source support part among the plurality of replenishment support parts in the replenishment unit as transfer support parts for supporting the feeders for transfer from the first storage unit to the second storage unit. In this case, in the feeder arrangement process, the management device operates the operation unit so that the feeder to be replenished stored in the first storage unit or the second storage unit moves and is supported by the replenishment source support part, and also operates the operation unit so that the transfer feeder stored in the first storage unit moves and is supported by the transfer support part. Further, in the replenishment process, the management device operates the operation unit so that the feeder to be replenished supported by the replenishment source support part moves and is replenished to the supply support part of the replenishment destination. Then, in a state where the replenishment device is moved to a position facing the second storage unit, the management device performs a transfer process of operating the operation unit so that the transfer feeder supported by the transfer support part moves to the second storage unit.

[0117] There may be a case where the number of feeders to be replenished, which requires replenishment for each component supply unit of each component mounting machine, is less than the number of replenishment support parts in the replenishment unit of the replenishment device. In this case, in the setting process, the management device sets, as a transfer support part for supporting the transfer feeders from the first storage unit to the second storage unit, the remaining replenishment support parts excluding the replenishment source support part among the plurality of replenishment support parts in the replenishment unit. When the transfer support part is set in the replenishment unit of the replenishment device in this way, the management device operates the operation unit so that the transfer feeders stored in the first storage unit move and are supported by the transfer support part in the feeder arrangement process. Then, the management device performs a transfer process of operating the operation unit so that the transfer feeders supported by the transfer support part move to the second storage unit in a state where the replenishment device is moved to a position facing the second storage unit. Thereby, when the number of feeders to be replenished is less than the number of replenishment support parts in the replenishment unit of the replenishment device, the feeders stored in the first storage unit can be replenished to the second storage unit as transfer feeders.

[0118] In the above component mounting system, the plurality of mounting lines are installed such that the distances from the first storage unit are different from each other, and the second storage unit may be installed at a position closer to the first storage unit than the first storage unit for a specific mounting line whose distance from the first storage unit is equal to or greater than a predetermined distance. In this case, in the setting process, the management device preferentially sets, as the replenishment destination of the transfer feeders, the component supply unit corresponding to the specific mounting line among each of the component supply units corresponding to the plurality of mounting lines.

[0119] In this aspect, a plurality of mounting lines are installed such that the distances from the first storage unit are different from each other, and the second storage unit is installed closer to a specific mounting line having a distance from the first storage unit equal to or greater than a predetermined distance than the first storage unit. In this case, when replenishing the feeder to be replenished to the component supply unit corresponding to the specific mounting line by the replenishing device, as the movement path of the replenishing device, the path of moving the replenishing device between the component supply unit and the second storage unit is selected rather than the path of moving the replenishing device between the component supply unit and the first storage unit, so that the moving distance of the replenishing device can be shortened. Thereby, it becomes possible to improve the replenishing efficiency of the feeder to the component supply unit corresponding to the specific mounting line.

[0120] In this case, among the plurality of feeders stored in the second storage unit, the feeder replenished to the component supply unit corresponding to the specific mounting line is taken out from the second storage unit with a high frequency. Therefore, in the setting process, when setting the transfer support unit that supports the feeder for transfer from the first storage unit to the second storage unit, the management device preferentially sets the component supply unit corresponding to the specific mounting line as the replenishment destination of the feeder for transfer. Thereby, the feeder replenished to the component supply unit corresponding to the specific mounting line can be transferred from the first storage unit to the second storage unit as the feeder for transfer and replenished to the second storage unit.

[0121] In the above-described component mounting system, the replenishment unit may be movable within a predetermined allowable movement range in the arrangement direction of the plurality of replenishment support parts. In this case, in the setting process, the management device assumes that the replenishment unit moves within the allowable movement range with respect to each component supply unit, recognizes the position range in which the replenishment support parts can face the supply support part of the replenishment destination among the plurality of replenishment support parts, and when the replenishment support part outside the position range with respect to the supply support part of the replenishment destination is set as the replenishment support part of the replenishment source, range-out information is added to the replenishment support part of the replenishment source. Further, in the replenishment process, the management device moves the replenishment unit within the allowable movement range so that the replenishment support part of the replenishment source without the addition of the range-out information faces the supply support part of the replenishment destination, and then operates the operation unit so that the feeder to be replenished supported by the replenishment support part of the replenishment source moves and is replenished to the supply support part of the replenishment destination. Then, with the feeder to be replenished supported by the replenishment support part of the replenishment source to which the range-out information is added, the management device moves the replenishment device to a position facing the second storage unit, and performs a support position change process of operating the operation unit so that the feeder to be replenished moves to the replenishment support part within the position range via the second storage unit.

[0122] In this mode, in the replenishment device, the replenishment unit is movable within a predetermined allowable movement range in the arrangement direction of the plurality of replenishment support parts. In this case, in the setting process, the management device recognizes the position range in which the replenishment support parts can face the supply support part of the replenishment destination, assuming that the replenishment unit moves within the allowable movement range with respect to the component supply unit. Then, when the management device sets a replenishment support part outside the position range as the replenishment source support part with respect to the supply support part of the replenishment destination, it adds out-of-range information to the replenishment source support part. The replenishment source support part with the out-of-range information added thereto will not be arranged at a position facing the supply support part of the replenishment destination even if the replenishment unit moves within the allowable movement range with respect to the component supply unit. In this case, it is not possible to replenish the feeder to be replenished, which is supported by the replenishment source support part with the out-of-range information added thereto in the replenishment unit, to the supply support part of the replenishment destination in the component supply unit.

[0123] Therefore, the management device performs a support position change process of moving the replenishment device to a position facing the second storage unit in a state where the feeder to be replenished is supported by the replenishment source support part with the out-of-range information added thereto, and operating the operation unit so that the feeder to be replenished moves to the replenishment support part within the position range via the second storage unit. As a result, in the replenishment unit of the replenishment device, the feeder to be replenished, which was supported by the replenishment source support part with the out-of-range information added thereto, can be moved via the second storage unit to the replenishment support part within the position range where it can face the supply support part of the replenishment destination. Then, the feeder to be replenished that has been moved to the replenishment support part within the position range can be replenished to the supply support part of the replenishment destination in the component supply unit.

[0124] In the above component mounting system, when the management device acquires non-permission information that prohibits replenishment of the feeder to be replenished disposed in the replenishment unit in a state where the replenishment device has moved to a position facing each component supply unit, the management device moves the replenishment device to a position facing the second storage unit, and may perform a temporary placement process of operating the operation unit so that the feeder to be replenished corresponding to the non-permission information moves from the replenishment unit to the second storage unit.

[0125] In a plurality of mounting lines, non-permission information that prohibits replenishment of the feeder to be replenished to the component supply unit may be output from the component mounter. When the non-permission information is acquired in a state where the replenishment device has moved to a position facing the component supply unit, the management device moves the replenishment device to a position facing the second storage unit, and performs a temporary placement process of operating the operation unit so that the feeder to be replenished corresponding to the non-permission information moves from the replenishment unit to the second storage unit. Thereby, the feeder to be replenished corresponding to the non-permission information can be temporarily placed in the second storage unit.

[0126] As described above, according to the present invention, it is possible to provide a component mounting system capable of improving the replenishment efficiency of feeders for each component mounter in a plurality of mounting lines.
