Abstract
Description
【Technical Field】 【0001】 The present invention relates to a production management device, a production management method, and a production system for managing the production of a substrate on which components are mounted. 【Background Art】 【0002】 In a production line for producing a substrate on which components are mounted, in order to improve the productivity of the substrate, it is known to connect a plurality of mounters in the conveyance direction of the substrate. Each mounter has a plurality of feeder mounting parts to which a feeder for supplying components to be mounted on the substrate is detachably attached. Each mounter mounts the components supplied by the feeders attached to each feeder mounting part on the substrate. 【0003】 When producing substrates of a plurality of types of substrate types in a production line, the components used in production may differ for each substrate type. Therefore, every time the substrate type is switched, it is necessary to perform an exchange operation of exchanging the feeders used for component supply for each feeder mounting part of each mounter. 【0004】 Patent Document 1 discloses a technique for determining the arrangement position of feeders for each feeder mounting part of each mounter in consideration of the feeder exchange operation accompanying the switching of substrate types. In the technique disclosed in Patent Document 1, after determining the arrangement position of the feeders for each feeder mounting part of each mounter, the arrangement positions of the feeders are interchanged between the mounters so as to balance the cycle time or production time in each mounter. 【Prior Art Documents】 【Patent Documents】 【0005】 【Patent Document 1】 Japanese Patent No. 6267127 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0006】 In production lines with multiple mounting machines connected together, as the number of connected machines increases, the number of work locations required for feeder replacement for each mounting machine when switching between board types tends to increase. In this case, the number of movements to work locations for replacement work with each board type change increases, and the distance traveled between work locations also increases, leading to a problem of decreased work efficiency for replacement work. When the work efficiency of replacement work with each board type change decreases, there is a higher possibility that the replacement work will not be completed within the board type changeover period, and the production of the next board will be stopped, which may reduce the productivity of the boards. 【0007】 The object of the present invention is to provide a production management device, a production management method, and a production system that can improve the work efficiency of feeder replacement work associated with switching substrate types in a production line in which multiple mounting machines are connected. [Means for solving the problem] 【0008】 A production management device according to one aspect of the present invention is a device for managing the production of multiple types of substrates in a production line in which multiple mounting machines, each having a plurality of feeder mounting sections on which feeders for supplying components to be mounted on substrates are detachably mounted, are connected in the transport direction of the substrates. The production management device includes a component classification unit that classifies the components used in the production of multiple types of substrates in the production line into a common component group, which represents a set of components used in common for all types of substrates, and a plurality of individual component groups, each representing a set of components used individually for each type of substrate; and a mounting position determination unit that determines the mounting position of a common feeder group, which represents a set of feeders used for supplying components belonging to the common component group, and determines the mounting position of a plurality of individual feeder groups, each representing a set of feeders used for supplying components belonging to each of the plurality of individual component groups, for a plurality of feeder mounting sections of each of the plurality of mounting machines. The mounting position determination unit distributes the mounting positions of the feeders belonging to the common feeder group to each of the multiple mounting machines, and concentrates the mounting positions of the feeders belonging to each of the multiple individual feeder groups to a portion of the multiple mounting machines for each individual feeder group. 【0009】 According to this production management system, the mounting position of feeders for supplying components used in the production of circuit boards in a production line consisting of multiple connected mounting machines is determined for each feeder mounting section of each mounting machine. In this process, the production management system determines the mounting position of a common feeder group for supplying common component groups used in common across multiple circuit board types, as well as the mounting positions of multiple individual feeder groups for supplying multiple individual component groups used individually for each circuit board type. In this case, with the feeders belonging to the common feeder group and the feeders belonging to each individual feeder group mounted on the respective feeder mounting sections of each mounting machine, circuit boards of multiple circuit board types are produced on the production line. When switching between circuit board types produced on the production line, it is not necessary to replace the feeders belonging to the common feeder group, but it is necessary to replace the feeders belonging to the individual feeder groups with the individual feeder groups corresponding to the circuit board type being produced. Therefore, the mounting position of the feeders belonging to each individual feeder group on each mounting machine affects the feeder replacement work associated with switching between circuit board types. 【0010】 Therefore, the production management system distributes the mounting positions of feeders belonging to a common feeder group across multiple mounting machines, while consolidating the mounting positions of feeders belonging to each of multiple individual feeder groups onto a portion of the multiple mounting machines for each individual feeder group. By consolidating the mounting positions of feeders belonging to individual feeder groups in this way, the number of work locations required for replacement work targeting individual feeder groups each time the substrate type changes can be reduced compared to when the mounting positions are distributed. As a result, the number of movements to work locations for replacement work each time the substrate type changes is reduced, and the distance traveled during replacement work is also shortened, making it possible to improve the work efficiency of feeder replacement work associated with substrate type changes. Therefore, it is possible to suppress the cessation of substrate production on the production line due to feeder replacement work and suppress the decrease in substrate productivity. 【0011】 In the above-described production management device, the mounting position determination unit may divide the multiple feeder mounting sections of each of the multiple mounting machines into a plurality of first mounting sections and a plurality of second mounting sections, determine the plurality of the aforementioned first mounting sections as mounting positions for the feeders belonging to the common feeder group, and determine the plurality of the aforementioned second mounting sections as mounting positions for the feeders belonging to the individual feeder group. 【0012】 In this embodiment, at each feeder mounting section of each mounting machine, feeders belonging to a common feeder group are mounted at the first mounting section, and feeders belonging to individual feeder groups are mounted at the second mounting section, and production of multiple types of substrates is carried out on the production line. In this case, since there are multiple second mounting sections at each feeder mounting section of each mounting machine, which serve as mounting positions for individual feeder groups, it is possible to consolidate the mounting positions of multiple feeders on the mounting machine even when there are multiple feeders belonging to individual feeder groups. This makes it possible to effectively improve the work efficiency of feeder replacement work when switching substrate types. 【0013】 The above-described production management device may further include a work management unit that manages replacement work, which involves replacing the individual feeder groups attached to the second mounting section of each of the multiple mounting machines, as work performed each time the type of substrate produced on the production line is changed. In this case, the mounting position determination unit may determine the mounting position of each of the multiple individual feeder groups for each of the second mounting sections of the multiple mounting machines, such that the work position of the replacement work is displaced from upstream to downstream in the transport direction each time the type of substrate is changed. 【0014】 In this embodiment, when a feeder replacement operation is performed for a group of individual feeders mounted on the second mounting section of the mounting machine in conjunction with a change in substrate type, the work position for the replacement operation is displaced from upstream to downstream in the substrate transport direction each time the substrate type is changed. In this case, the travel distance during the replacement operation can be shortened compared to when the work position for the replacement operation is displaced in multiple directions, including the opposite direction of the transport direction. This makes it possible to effectively improve the work efficiency of the feeder replacement operation in conjunction with a change in substrate type. 【0015】 In the above-described production management device, the mounting position determination unit recognizes the order of use of the multiple individual feeder groups based on the production order of the multiple substrate types, and may consolidate the mounting positions of the multiple individual feeder groups targeting the second mounting section of each of the multiple mounting machines, with the individual feeder groups with higher usage order being located on the mounting machine located upstream in the transport direction compared to the individual feeder groups with lower usage order. 【0016】 In this embodiment, the production management device concentrates the individual feeder groups, which are positioned for the second mounting section of each mounting machine, on mounting machines located upstream in the substrate transport direction from the lower-ranking individual feeder groups, based on the production order of the substrate types. In this case, when feeder replacement work is performed for the individual feeder groups mounted on the second mounting section of the mounting machine due to a change in substrate type, the work position for the replacement work can be shifted from upstream to downstream in the substrate transport direction each time the substrate type is changed. This makes it possible to shorten the travel distance during replacement work, thereby effectively improving the work efficiency of feeder replacement work due to substrate type changes. 【0017】 In the production management device described above, the work management unit may output work request information requesting the execution of the replacement work during the substrate type changeover period, which is from the end of production of one substrate type to the start of production of the next substrate type. 【0018】 In this embodiment, work request information is output during the substrate type changeover period. In this case, the operator or work robot can check the work request information and perform the feeder replacement work during the substrate type changeover period. 【0019】 In the above-described production management device, the mounting position determination unit may adjust the number of feeders belonging to the individual feeder group that are consolidated into a portion of the multiple mounting machines, such that the work time for the replacement operation is less than or equal to the production time required for the production of the substrate. 【0020】 In this embodiment, the production management device adjusts the number of aggregated feeders when consolidating feeders belonging to individual feeder groups at the mounting machine, within a range where the work time for replacement work on individual feeder groups associated with switching substrate types is less than or equal to the production time of substrates on the production line. In this case, adjusting to increase the number of aggregated feeders makes it possible to improve the work efficiency of feeder replacement work associated with switching substrate types. On the other hand, adjusting to decrease the number of aggregated feeders makes it possible to improve the productivity of substrates on the production line by gently distributing the mounting positions of feeders belonging to individual feeder groups to each mounting machine, within a range where the work time for replacement work is less than or equal to the production time. 【0021】 The production management method according to another aspect of the present invention is a method for managing the production of substrates for a plurality of substrate types in a production line in which a plurality of mounters having a plurality of feeder mounting parts to which feeders for supplying components mounted on the substrates are detachably mounted are connected in series in the conveyance direction of the substrates. This production management method classifies the components used in the production of the substrates for each of the plurality of substrate types in the production line into a common component group indicating a set of components commonly used for all the substrate types and a plurality of individual component groups respectively indicating a set of components individually used for each substrate type, and performs a component classification process. For each of the plurality of feeder mounting parts of each of the plurality of mounters, a mounting position determination process is performed to determine the mounting position of a common feeder group indicating a set of feeders used for supplying the components belonging to the common component group, and to determine the mounting positions of a plurality of individual feeder groups respectively indicating a set of feeders used for supplying the components belonging to each of the plurality of individual component groups. In the mounting position determination process, the mounting positions of the feeders belonging to the common feeder group are dispersed among each of the plurality of mounters, and the mounting positions of the feeders belonging to each of the plurality of individual feeder groups are aggregated in a part of the plurality of mounters for each individual feeder group. 【0022】 In addition, a production system according to another aspect of the present invention includes a production line in which a plurality of mounters having a plurality of feeder mounting parts to which feeders for supplying components mounted on substrates are detachably mounted are connected in series in the conveyance direction of the substrates, and the above-described production management device that manages the production of the substrates for each of the plurality of substrate types in the production line. 【Advantages of the Invention】 【0023】 As described above, according to the present invention, it is possible to provide a production management device, a production management method, and a production system that can improve the work efficiency of the feeder replacement work accompanying the switching of the substrate type in a production line in which a plurality of mounters are connected in series. 【Brief Description of the Drawings】 【0024】 [Figure 1]It is a diagram schematically showing the configuration of a production system to which a production management apparatus according to an embodiment of the present invention is applied.

The production system PS comprises a production line PL and a production management device 1. The production line PL is a component mounting line for producing substrates B on which components A are mounted. The production management device 1 is a device that manages the production of substrates B for each of several types of substrates BT1 to BT6 in the production line PL. In the following description, the production line PL will sequentially produce substrates B of six types of substrates BT1 to BT6. The production management device 1 then manages the production of substrates B of six types of substrates BT1 to BT6 in the production line PL. 【0027】 In the production line PL, the printing press PM, the print inspection machine PIM, multiple mounting machines 2, the reflow machine RM, and the board inspection machine BIM are arranged in tandem on the board transport path TP that transports boards B, from upstream to downstream in the board transport direction H1, and are connected to each other. At the upstream end of the production line PL, there is a loader LD that loads boards B into the printing press PM, and at the downstream end, there is an unloader ULD that removes the finished boards B from the board inspection machine BIM. 【0028】 The PM printer prints solder paste, such as solder paste, onto substrate B using a screen printing method, for example. The PM printer is equipped with a printing unit PU for printing solder paste onto substrate B. The printing unit PU captures an image of substrate B, and based on this image, it recognizes FID (fiducial) marks and the size of substrate B, moves over substrate B, and prints solder paste onto substrate B. 【0029】 The Printed Inspection Machine (PIM) inspects whether the position, amount, and height of the solder paste printed on substrate B are correct. The Printed Inspection Machine (PIM) is equipped with a Printed Inspection Unit (PIU) that inspects the printing condition of the solder paste on substrate B. The Printed Inspection Unit (PIU) captures an image of substrate B on which the solder paste is printed, and based on this image, it moves above substrate B while recognizing the FID mark and the size of substrate B, and inspects the printing condition of the solder paste on substrate B. 【0030】 Multiple mounting machines 2 are connected to each other on the substrate transport path TP of the production line PL. In the following description, the multiple mounting machines 2 are assumed to consist of three machines: the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C. The three first mounting machines 2A, the second mounting machine 2B, and the third mounting machine 2C are arranged in tandem on the substrate transport path TP, from upstream to downstream in the substrate transport direction H1, and are connected to each other. Each mounting machine 2, the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C, mounts components A onto a substrate B on which solder paste has been printed. Details of each mounting machine 2 will be described later. 【0031】 The reflow machine RM heats the circuit board B on which component A is mounted in each mounting machine 2 to melt the solder and fix component A to the circuit board B. 【0032】 The BIM (Band Inspection Machine) is a device that inspects a circuit board B on which component A is mounted, and is positioned at the downstream end of the circuit board transport direction H1 in the production line PL. The BIM inspects for misalignment, lead misalignment, component lifting, mounting omissions, soldering defects, and foreign matter inclusion of component A on circuit board B. The BIM is equipped with a BIU (Band Inspection Unit) for inspecting circuit board B. The BIU captures images of circuit board B and acquires the captured images. Based on these captured images, it moves above circuit board B, recognizing the FID marks on circuit board B, the size of circuit board B, and the position of component A on circuit board B, and inspects for misalignment of component A, etc. 【0033】 [Detailed configuration of the implementation unit] The first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C will be described in detail with reference to Figure 2. In the following, directional relationships will be explained using the XYZ Cartesian coordinate axes. The X-axis and Y-axis directions are mutually orthogonal on the horizontal plane, and the Z-axis direction is a vertical direction that is orthogonal to both the X-axis and Y-axis directions. 【0034】 Each mounting machine 2 comprises a mounting machine body 21, a transport conveyor 22, a parts supply unit 23, and a head unit 26. 【0035】 The mounting machine body 21 is a housing having an internal space in which the various parts constituting the mounting machine 2 are arranged. The transport conveyor 22 extends in the Y-axis direction and is located in the approximately central region inside the mounting machine body 21. The transport conveyor 22 transports the substrate B in the Y-axis direction, which is the same direction as the substrate transport direction H1. The head unit 26 mounts components A onto the substrate B transported by the transport conveyor 22. The head unit 26 takes components A from the feeder 25 located in the component supply unit 23 and mounts the taken components A onto the substrate B. The head unit 26 is equipped with a plurality of suction nozzles 261. The suction nozzles 261 are holders capable of adsorbing and holding components A. The suction nozzles 261 can communicate with a negative pressure generator, a positive pressure generator, or the atmosphere via an electric switching valve. In other words, when negative pressure is supplied to the suction nozzle 261, the suction nozzle 261 becomes able to hold part A by suction, and then when positive pressure is supplied, the suction holding of part A is released. 【0036】 The component supply unit 23 is positioned in the X-axis direction end region of the mounting machine body 21. The component supply unit 23 has an upper frame 231, a lower frame 232, and a rear frame 233 for forming a plurality of feeder mounting sections 24a to 24k on which feeders 25 for supplying component A are detachably mounted. The upper frame 231 is a plate-shaped frame that extends in the X-axis direction and the Y-axis direction. The upper frame 231 is positioned at one end of the mounting machine body 21 in the X-axis direction such that a portion of the region on one end in the X-axis direction is exposed outward from the mounting machine body 21, while a portion of the region on the other end in the X-axis direction is housed inside the mounting machine 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 positioned below the upper frame 231 in the Z-axis direction and opposite to the upper frame 231. The lower frame 232 has a projection 2321 that protrudes upward in the Z-axis direction from the region on the other end in the X-axis direction that is housed inside the mounting machine body 21. The rear frame 233 is a plate-shaped frame that extends in the Y-axis and Z-axis directions, and is positioned closer to the center of the mounting machine body 21 than the other ends of the upper frame 231 and lower frame 232 in the X-axis direction. 【0037】 Each of the multiple feeder mounting sections 24a to 24k is detachably fitted with a feeder 25 in the parts supply unit 23. In the parts supply unit 23, the multiple feeder mounting sections 24a to 24k are arranged in the Y-axis direction. By fitting a feeder 25 to each of these feeder mounting sections 24a to 24k, multiple feeders 25 are arranged in the Y-axis direction. In the following description, it is assumed that the parts supply unit 23 has 11 feeder mounting sections 24a to 24k. 【0038】 The feeder 25 is configured to supply parts, but the method of supplying parts is not particularly limited. Examples of feeders 25 include a tape feeder that supplies parts A using tape as a carrier, a tray feeder that supplies parts A by moving a tray on which parts A are placed, and a stick feeder that supplies parts A stored in a cylindrical stick by pushing them out of the stick. 【0039】 The following describes the case where a tape feeder is used as the feeder 25. The feeder 25 supplies parts A by discharging a parts storage tape PT capable of storing multiple parts A. The parts storage tape PT consists of a carrier tape PT1 having multiple storage sections for storing parts, and a cover tape PT2 joined to the carrier tape PT1 so as to cover the storage sections. The feeder 25 includes a feeder body 251, a reel support section 252, a tape discharging section 254, and a retrieval section 255. 【0040】 The feeder body 251 has a tape delivery path 253. The tape delivery path 253 is the path through which the component storage tape PT is delivered, and has a component removal section 2531 between the upstream end and the downstream end in the delivery direction of the component storage tape PT. The reel support section 252 is located on the upstream end side of the tape delivery path 253 in the feeder body 251. The reel support section 252 supports the reel on which the component storage tape PT is wound. 【0041】 The tape delivery unit 254 is composed of, for example, a sprocket and is located near the component removal unit 2531 of the tape delivery path 253. The tape delivery unit 254 unwinds the component storage tape PT from a reel supported by the reel support unit 252 and delivers the unwinded component storage tape PT along the tape delivery path 253. The operation of the tape delivery unit 254 is controlled by a control circuit mounted on the control board 259. As the component storage tape PT is delivered along the tape delivery path 253, the cover tape PT2 is peeled off from the carrier tape PT1 upstream of the component removal unit 2531. As a result, component A is exposed on the carrier tape PT1 at the component removal unit 2531. Component A exposed on the carrier tape PT1 can be removed by the head unit 26. In other words, the head unit 26 removes component A supplied by the feeder 25 from the component removal unit 2531. 【0042】 Upstream of the parts removal section 2531, the cover tape PT2 that has been peeled off from the carrier tape PT1 is collected by the collection section 255. The collection section 255 is composed of, for example, a pair of rollers that are in contact with each other. In this case, the collection section 255 collects the cover tape PT2 in accordance with the rotation of the pair of rollers. The cover tape PT2 collected by the collection section 255 is stored in the collection box 2551. 【0043】 After component A is removed by the head unit 26, the carrier tape PT1 is fed outward from the feeder 25 via the downstream end of the tape feed path 253 by the feed operation of the tape feed unit 254. The carrier tape PT1 fed outward from the feeder 25 is cut to a predetermined length by the tape cutter 23A located near the protrusion 2321 of the lower frame 232 in the component supply unit 23. 【0044】 As shown in Figure 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 that protrude from one end of the feeder body 251 in the X-axis direction. The upper positioning pin 256 and the lower positioning pin 257 are spaced apart from each other in the Z-axis direction at one end of the feeder body 251 in the X-axis direction, with the upper positioning pin 256 positioned above the lower positioning pin 257. The end of the feeder body 251 in the X-axis direction has a stepped portion that is recessed on the other side in the X-axis direction relative to the portion where the upper positioning pin 256 and the lower positioning pin 257 are provided. The feeder-side connector 258 is provided on this stepped portion at the end 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. 【0045】 Multiple feeder mounting sections 24a to 24k, to which the feeder 25 is detachably attached, are formed on the upper frame 231, lower frame 232, and rear frame 233 of the parts supply unit 23. Each feeder mounting section 24a to 24k 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. 【0046】 Multiple upper holding rails 241 are formed on the lower surface of the upper frame 231, extending in the X-axis direction and arranged in the Y-axis direction. The upper holding rails 241 are rail members that guide the upper end of the feeder 25 when it is moved to and from the feeder mounting portions 24a to 24k. Multiple lower holding rails 242 are formed on the upper surface of the lower frame 232, extending in the X-axis direction and arranged in the Y-axis direction. The lower holding rails 242 are rail members that guide the lower end of the feeder 25 when it is moved to and from the feeder mounting portions 24a to 24k. 【0047】 The upper pin insertion holes 243 are multiple holes formed in the upper end of the rear frame 233, aligned in the Y-axis direction. The upper pin insertion holes 243 allow the insertion of the upper positioning pin 256 of the feeder 25 when the feeder 25 is mounted on the feeder mounting sections 24a to 24k. On the other hand, when the feeder 25 is removed from the feeder mounting sections 24a to 24k, the insertion of the upper positioning pin 256 into the upper pin insertion holes 243 is released. The lower pin insertion holes 244 are multiple holes formed in the lower end of the rear frame 233, aligned in the Y-axis direction. The lower pin insertion holes 244 allow the insertion of the lower positioning pin 257 of the feeder 25 when the feeder 25 is mounted on the feeder mounting sections 24a to 24k. On the other hand, when the feeder 25 is removed from the feeder mounting sections 24a to 24k, the insertion of the lower positioning pin 257 into the lower pin insertion holes 244 is released. The feeder 25 is positioned relative to the feeder mounting sections 24a to 24k by inserting the upper positioning pin 256 into the upper pin insertion hole 243 and the lower positioning pin 257 into the lower pin insertion hole 244. 【0048】 The unit-side connectors 245 are provided in multiple locations along the Y-axis direction on the protrusions 2321 of the lower frame 232 and are connectors that are electrically connected to the control unit of the mounting machine 2. The unit-side connectors 245 are connected to the feeder-side connectors 258 of the feeder 25 when the feeder 25 is mounted on the feeder mounting sections 24a to 24k. 【0049】 [Detailed configuration of the production control system] The production management device 1 manages the production of substrates B for each of the multiple substrate types BT1 to BT6 in a production line PL, which is composed of multiple mounting machines 2: a first mounting machine 2A, a second mounting machine 2B, and a third mounting machine 2C. The production management device 1 is composed of a processor that operates by loading a predetermined program. As shown in Figure 1, the production management device 1 includes a component classification unit 11, a mounting position determination unit 12, a production processing unit 13, and a work management unit 14 as functional configurations for performing various processes to manage the production of substrates B in the production line PL. 【0050】 The various processes performed by the production management device 1 will be explained with reference to Figures 3 to 8. The production management device 1 executes various processes of a production management method that manages the production of substrate B for each of the multiple substrate types BT1 to BT6 in the production line PL by having the parts classification unit 11 perform parts classification processing, the mounting position determination unit 12 perform mounting position determination processing, the production processing unit 13 perform production processing, and the work management unit 14 perform work management processing. 【0051】 (Regarding parts classification processing) The component classification process of the component classification unit 11 will be explained with reference to Figures 3, 4, and 5. The total number of component types AT01 to AT42 of component A used in the production of board B for each of the multiple board types BT1 to BT6 in the production line PL is usually greater than the total number of feeder mounting sections 24a to 24k in the three mounting machines 2: the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C. In the following explanation, it will be assumed that there are 42 types of component types AT01 to AT42 of component A used in the production of board B in the production line PL, which is greater than the total number of feeder mounting sections 24a to 24k in the three mounting machines 2, which is "33 = 11 × 3". 【0052】 The component classification unit 11 classifies the 42 types of component A, AT01 to AT42, into a common component group AGA, which represents a set of component A used in common by all six types of boards BT1 to BT6, and multiple individual component groups AGB1 to AGB6, which represent sets of component A used individually for each of the six types of boards BT1 to BT6. In the multiple individual component groups AGB1 to AGB6, the set of component A used individually for board type BT1 is designated as the first individual component group AGB1, the set of component A used individually for board type BT2 is designated as the second individual component group AGB2, the set of component A used individually for board type BT3 is designated as the third individual component group AGB3, the set of component A used individually for board type BT4 is designated as the fourth individual component group AGB4, the set of component A used individually for board type BT5 is designated as the fifth individual component group AGB5, and the set of component A used individually for board type BT6 is designated as the sixth individual component group AGB6. 【0053】 In the example shown in Figure 4, the common component group AGA includes 24 types of component A, numbered AT01 to AT24. The number of these 24 types of component A belonging to the common component group AGA is greater than the number of feeder mounting sections 24a to 24k in one mounting machine 2 ("11"), and less than the total number of feeder mounting sections 24a to 24k in three mounting machines 2 ("33"). 【0054】 Furthermore, in the example shown in Figure 5, the first individual component group AGB1 includes three types of component A, AT25 to AT27. The number of these three types of component A belonging to the first individual component group AGB1 is less than the number of each feeder mounting section 24a to 24k in one mounting machine 2, which is "11". The second individual component group AGB2 includes three types of component A, AT28 to AT30. The number of these three types of component A belonging to the second individual component group AGB2 is less than the number of each feeder mounting section 24a to 24k in one mounting machine 2, which is "11". The third individual component group AGB3 includes three types of component A, AT31 to AT33. The number of parts A of the three types of parts AT31 to AT33 belonging to this third individual parts group AGB3 is less than the number of "11" for each feeder mounting section 24a to 24k in one mounting machine 2. The fourth individual parts group AGB4 includes parts A of three types of parts AT34 to AT36. The number of parts A of the three types of parts AT34 to AT36 belonging to this fourth individual parts group AGB4 is less than the number of "11" for each feeder mounting section 24a to 24k in one mounting machine 2. The fifth individual parts group AGB5 includes parts A of three types of parts AT37 to AT39. The number of parts A of the three types of parts AT37 to AT39 belonging to this fifth individual parts group AGB5 is less than the number of "11" for each feeder mounting section 24a to 24k in one mounting machine 2. The sixth individual parts group AGB6 includes parts A of three types of parts AT40 to AT42. The number of component A of the three component types AT40 to AT42 belonging to this sixth individual component group AGB6 is less than the number of "11" in each feeder mounting section 24a to 24k of one mounting machine 2. 【0055】 (Regarding the process of determining the mounting position, production process, and work management process) The mounting position determination process of the mounting position determination unit 12 will be explained with reference to Figures 3, 6, 7, and 8. The mounting position determination unit 12 determines the mounting position of the common feeder group FGA, which is a collection of 24 feeders 25 used to supply parts A of 24 types of parts AT01 to AT24 belonging to the common parts group AGA, for each feeder mounting section 24a to 24k of the three mounting machines 2: the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C. Furthermore, the mounting position determination unit 12 determines the mounting position of the first individual feeder group FGB1, which represents a set of three feeders 25 used to supply parts A of three types of parts AT25 to AT27 belonging to the first individual parts group AGB1; determines the mounting position of the second individual feeder group FGB2, which represents a set of three feeders 25 used to supply parts A of three types of parts AT28 to AT30 belonging to the second individual parts group AGB2; and mounts the third individual feeder group FGB3, which represents a set of three feeders 25 used to supply parts A of three types of parts AT31 to AT33 belonging to the third individual parts group AGB3. The position is determined, and the mounting position of the fourth individual feeder group FGB4, which represents a collection of three feeders 25 used to supply parts A of three types of parts AT34 to AT36 belonging to the fourth individual part group AGB4, is determined, the mounting position of the fifth individual feeder group FGB5, which represents a collection of three feeders 25 used to supply parts A of three types of parts AT37 to AT39 belonging to the fifth individual part group AGB5, is determined, and the mounting position of the sixth individual feeder group FGB6, which represents a collection of three feeders 25 used to supply parts A of three types of parts AT40 to AT42 belonging to the sixth individual part group AGB6 is determined. 【0056】 With the mounting positions of the 24 feeders 25 belonging to the common feeder group FGA determined, and the mounting positions of the three feeders 25 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6 determined, the production processing unit 13 performs production processing to sequentially produce substrate B for each of the six substrate types BT1 to BT6 on the production line PL. 【0057】 When switching between substrate types BT1 to BT6 for substrate B produced on the production line PL, feeder 25 belonging to the common feeder group FGA does not need to be replaced. However, feeders 25 belonging to the first individual feeder group FGB1, second individual feeder group FGB2, third individual feeder group FGB3, fourth individual feeder group FGB4, fifth individual feeder group FGB5, and sixth individual feeder group FGB6, respectively, need to be replaced by an operator or work robot to change them to the individual feeder group corresponding to the substrate types BT1 to BT6 being produced. Therefore, the mounting positions of the feeders 25 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, respectively, on the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C, respectively, affect the feeder 25 replacement work associated with switching between substrate types BT1 to BT6. 【0058】 Therefore, the mounting position determination unit 12 evenly distributes the mounting positions of the 24 feeders 25 belonging to the common feeder group FGA, with 8 feeders each in the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C. Then, the mounting position determination unit 12 concentrates the mounting positions of the 3 feeders 25 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, in a portion of the mounting machines 2 of the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C for each individual feeder group. Consolidating each individual feeder group into a portion of the first mounting machine 2A, second mounting machine 2B, and third mounting machine 2C includes consolidating each individual feeder group into one mounting machine 2 from among the first mounting machines 2, or, for example, if the number of connected mounting machines 2 is three or more, consolidating each individual feeder group into two mounting machines 2 that are adjacent to each other in the substrate transport direction H1. 【0059】 Specifically, we assume a case where the total number of feeders 25 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, respectively, "18 = 3 × 6", is greater than "9 = 33 - 24", which is obtained by subtracting the total number of feeders 25 belonging to the common feeder group FGA, "24", from the total number of feeder mounting sections 24a to 24k in the three mounting machines 2, the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C, "33 = 11 × 3". In this case, the mounting position determination unit 12 divides the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6 into the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, which are the targets for initial mounting, to be mounted on the feeder mounting sections 24a to 24k of the three mounting machines 2, the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C, respectively, from the initial stage of production of substrate B in the production line PL, and the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, which are the targets for replacement work for these initial mounting targets. 【0060】 In this case, the mounting position determination unit 12 determines the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, and based on the production order of the six types of substrates BT1 to BT6 in the production line PL, the first three (the same number as the number of connected mounting machines 2) are targeted for initial mounting, while the lower three are targeted for replacement work: the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6. 【0061】 Then, the mounting position determination unit 12 concentrates the three feeders 25 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, and the third individual feeder group FGB3, which are the targets for initial mounting, into the first mounting machine 2A, the three feeders 25 belonging to the second individual feeder group FGB2 into the second mounting machine 2B, and the three feeders 25 belonging to the third individual feeder group FGB3 into the third mounting machine 2C. Furthermore, the mounting position determination unit 12 consolidates the three feeders 25 belonging to the fourth individual feeder group FGB4 into the first mounting machine 2A as targets for replacement work for the first individual feeder group FGB1, the three feeders 25 belonging to the fifth individual feeder group FGB5 into the second mounting machine 2B as targets for replacement work for the second individual feeder group FGB2, and the three feeders 25 belonging to the sixth individual feeder group FGB6 into the third mounting machine 2C as targets for replacement work for the third individual feeder group FGB3. 【0062】 As described above, by consolidating the mounting positions of the feeders 25 belonging to each of the first individual feeder group FGB1, second individual feeder group FGB2, third individual feeder group FGB3, fourth individual feeder group FGB4, fifth individual feeder group FGB5, and sixth individual feeder group FGB6, the number of work locations required for replacement work targeting each individual feeder group for each switching of substrate types BT1 to BT6 can be reduced compared to the case where the mounting positions are dispersed. In other words, if the mounting positions of the three feeders 25 belonging to each of the six individual feeder groups are evenly distributed across the three mounting machines 2, then the replacement work needs to be performed at a total of nine work locations: three for the first individual feeder group FGB1 and the fourth individual feeder group FGB4, three for the second individual feeder group FGB2 and the fifth individual feeder group FGB5, and three for the third individual feeder group FGB3 and the sixth individual feeder group FGB6, each corresponding to the three mounting machines 2. 【0063】 In contrast, if three feeders 25 are grouped separately for each of the six individual feeder groups, as shown in Figure 3, the exchange work only needs to be performed at a total of three work locations: one work location each for the exchange work between the first individual feeder group FGB1 and the fourth individual feeder group FGB4, one work location each for the exchange work between the second individual feeder group FGB2 and the fifth individual feeder group FGB5, and one work location each for the exchange work between the third individual feeder group FGB3 and the sixth individual feeder group FGB6. This reduces the number of moves to the work location for the exchange work each time the substrate type BT1 to BT6 is switched, and also shortens the distance traveled during the exchange work, thereby improving the work efficiency of the feeder 25 exchange work associated with the switching of substrate types BT1 to BT6. As a result, it is possible to suppress the cessation of production of substrate B on the production line PL due to the feeder 25 exchange work and suppress the decrease in the productivity of substrate B. 【0064】 In accordance with the mounting position determination result by the mounting position determination unit 12, the 24 feeders 25 belonging to the common feeder group FGA and the 3 feeders 25 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, and the third individual feeder group FGB3, respectively, which are the initial mounting targets, are mounted on the respective feeder mounting sections 24a to 24k of the three mounting machines 2, the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C. With these mounted, the production processing unit 13 performs production processing to sequentially produce substrates B for each of the six substrate types BT1 to BT6 on the production line PL. 【0065】 While the production processing unit 13 is performing production processing, the work management unit 14 performs work management processing to manage the replacement work of replacing the first individual feeder group FGB1, the second individual feeder group FGB2, and the third individual feeder group FGB3, which are to be initially installed, with the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, which are to be replaced, as shown in Figure 3. In this case, the work management unit 14 outputs work request information J1 requesting the implementation of the replacement work during the substrate type BT1 to BT6 switching period SP, which is from the end of production of one substrate type BT1 to BT6 until the start of production of the next substrate type BT1 to BT6. 【0066】 Specifically, the work management unit 14 outputs work request information J1 requesting the execution of an exchange operation between the first individual feeder group FGB1 and the fourth individual feeder group FGB4, with the first mounting machine 2A as the working position, during the transition period SP between substrate type BT1 and substrate type BT2. The work management unit 14 also outputs work request information J1 requesting the execution of an exchange operation between the second individual feeder group FGB2 and the fifth individual feeder group FGB5, with the second mounting machine 2B as the working position, during the transition period SP between substrate type BT2 and substrate type BT3. Furthermore, the work management unit 14 outputs work request information J1 requesting the execution of an exchange operation between the third individual feeder group FGB3 and the sixth individual feeder group FGB6, with the third mounting machine 2C as the working position, during the transition period SP between substrate type BT3 and substrate type BT4. In this case, the operator or work robot can perform the feeder 25 exchange operation during the transition period SP between substrate types BT1 to BT6 by confirming the work request information J1. 【0067】 Furthermore, in the mounting position determination process, the mounting position determination unit 12 may divide the feeder mounting sections 24a to 24k of the three mounting machines 2, the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C, into a plurality of first mounting sections 24A and a plurality of second mounting sections 24B, as shown in Figure 3. In the example shown in Figure 3, the mounting position determination unit 12 designates eight feeder mounting sections 24a to 24h as first mounting sections 24A and three feeder mounting sections 24i to 24k as second mounting sections 24B. The mounting position determination unit 12 then determines the mounting positions of the eight first mounting sections 24A in each of the three mounting machines 2's feeder mounting sections 24a to 24k as mounting positions for feeders 25 belonging to the common feeder group FGA, and the three second mounting sections 24B as mounting positions for the feeders 25 of the first individual feeder group FGB1, second individual feeder group FGB2, third individual feeder group FGB3, fourth individual feeder group FGB4, fifth individual feeder group FGB5, and sixth individual feeder group FGB6. 【0068】 Specifically, the mounting position determination unit 12 determines the mounting positions of eight first mounting sections 24A in each feeder mounting section 24a to 24k of the first mounting machine 2A as mounting positions for feeders 25 belonging to the common feeder group FGA, and the mounting positions of three second mounting sections 24B as mounting positions for feeders 25 belonging to the first individual feeder group FGB1 and the fourth individual feeder group FGB4, respectively. Furthermore, the mounting position determination unit 12 determines the mounting positions of eight first mounting sections 24A in each feeder mounting section 24a to 24k of the second mounting machine 2B as mounting positions for feeders 25 belonging to the common feeder group FGA, and the mounting positions of three second mounting sections 24B as mounting positions for feeders 25 belonging to the second individual feeder group FGB2 and the fifth individual feeder group FGB5, respectively. Furthermore, the mounting position determination unit 12 determines the mounting positions of the eight first mounting sections 24A in each feeder mounting section 24a to 24k of the third mounting machine 2C as mounting positions for feeders 25 belonging to the common feeder group FGA, and the three second mounting sections 24B as mounting positions for feeders 25 belonging to the third individual feeder group FGB3 and the sixth individual feeder group FGB6, respectively. In this case, since there are multiple second mounting sections 24B that become mounting positions for individual feeder groups in each feeder mounting section 24a to 24k of the three mounting machines 2, even if there are multiple feeders 25 belonging to individual feeder groups, it is possible to consolidate the mounting positions of these multiple feeders 25 for each mounting machine 2. This makes it possible to effectively improve the work efficiency of feeder 25 replacement work associated with switching between substrate types BT1 to BT6. Furthermore, in each of the three mounting machines 2, the positions of the feeder mounting sections 24a to 24k that constitute the first mounting section 24A do not need to be continuous with the substrate transport direction H1. Similarly, the positions of the feeder mounting sections that constitute the second mounting section 24B do not need to be continuous with the substrate transport direction H1. For example, in each of the three mounting machines 2, the feeder mounting sections 24a, 24c to 24f, and 24h to 24j may constitute the first mounting section 24A, and the feeder mounting sections 24b, 24g, and 24k may constitute the second mounting section 24B. 【0069】 Furthermore, as shown in Figure 3, the mounting position determination unit 12 may determine the mounting position of each individual feeder group with respect to the second mounting section 24B of each of the three mounting machines 2 such that the working position for replacement work related to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6 is displaced from upstream to downstream in the substrate transport direction H1 each time the substrate type BT1 to BT6 is switched. In the example shown in Figure 3, the working position for replacement work between the first individual feeder group FGB1 and the fourth individual feeder group FGB4 is the first mounting machine 2A, the working position for replacement work between the second individual feeder group FGB2 and the fifth individual feeder group FGB5 is the second mounting machine 2B, and the working position for replacement work between the third individual feeder group FGB3 and the sixth individual feeder group FGB6 is the third mounting machine 2C. Therefore, the work positions for the three replacement operations are displaced in the order of the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C, moving from upstream to downstream in the substrate transport direction H1. When the work position for the replacement operation is displaced in this way, moving from upstream to downstream in the substrate transport direction H1, the travel distance during the replacement operation can be shortened compared to when the work position for the replacement operation is displaced in multiple directions, including the opposite direction of the substrate transport direction H1. This makes it possible to effectively improve the work efficiency of the feeder 25 replacement operation associated with switching between substrate types BT1 to BT6. 【0070】 Furthermore, as shown in Figure 3, the mounting position determination unit 12 may recognize the usage order of the first individual feeder group FGB1, second individual feeder group FGB2, third individual feeder group FGB3, fourth individual feeder group FGB4, fifth individual feeder group FGB5, and sixth individual feeder group FGB6 based on the production order of substrate types BT1 to BT6, and determine the mounting position of each individual feeder group on the three mounting machines 2 based on that usage order. In other words, the mounting position determination unit 12 may concentrate the individual feeder groups with higher usage order on the mounting machine 2 located upstream in the substrate transport direction H1 compared to the individual feeder groups with lower usage order, for the mounting positions of each individual feeder group targeting the second mounting section 24B of each of the three mounting machines 2. 【0071】 In this case, the mounting position determination unit 12 concentrates the feeders 25 belonging to the first individual feeder group FGB1, which has the highest usage order, at the first mounting machine 2A located at the upstream end of the substrate transport direction H1, among the first individual feeder group FGB1, second individual feeder group FGB2, and third individual feeder group FGB3 that are the targets for initial mounting. The mounting position determination unit 12 then concentrates the feeders 25 belonging to the second individual feeder group FGB2, which has the second highest usage order, at the second mounting machine 2B, which is adjacent to the first mounting machine 2A on the downstream side of the substrate transport direction H1, and concentrates the feeders 25 belonging to the third individual feeder group FGB3, which has the third highest usage order, at the third mounting machine 2C located at the downstream end of the substrate transport direction H1. Furthermore, the mounting position determination unit 12 consolidates the mounting position of the fourth individual feeder group FGB4, which is the target of replacement work for the first individual feeder group FGB1, to the first mounting machine 2A, the same as the first individual feeder group FGB1; consolidates the mounting position of the fifth individual feeder group FGB5, which is the target of replacement work for the second individual feeder group FGB2, to the second mounting machine 2B, the same as the second individual feeder group FGB2; and consolidates the mounting position of the sixth individual feeder group FGB6, which is the target of replacement work for the third individual feeder group FGB3, to the third mounting machine 2C, the same as the third individual feeder group FGB3. In this case, when feeder 25 replacement work is performed for individual feeder groups mounted on the second mounting section 24B of the three mounting machines 2 in conjunction with switching between substrate types BT1 to BT6, the work position for the replacement work can be displaced from upstream to downstream in the substrate transport direction H1 each time the substrate type BT1 to BT6 is switched. This makes it possible to shorten the travel distance during replacement work, thereby effectively improving the work efficiency of replacing the feeder 25 when switching between substrate types BT1 to BT6. 【0072】 (Regarding variations in the process for determining the mounting position) A modified example of the mounting position determination process performed by the mounting position determination unit 12 in the production management device 1 will be explained with reference to Figures 9, 10, and 11. 【0073】 In the above embodiment, the mounting position determination unit 12 was described as consolidating three feeders 5 belonging to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6 into one mounting machine 2 for each individual feeder group, but the embodiment is not limited to this. 【0074】 The mounting position determination unit 12 may recognize the work time WT for the replacement work related to the first individual feeder group FGB1, the second individual feeder group FGB2, the third individual feeder group FGB3, the fourth individual feeder group FGB4, the fifth individual feeder group FGB5, and the sixth individual feeder group FGB6, and the production time PTT for the substrate B in the production line PL, and determine the mounting position for each individual feeder group on each mounting machine 2 based on these times. The work time WT for the replacement work is expressed as the sum of the time spent by the operator or work robot performing the replacement work and the travel time during the replacement work. The production time PTT for the substrate B in the production line PL is expressed as the time obtained by multiplying the cycle time required to produce one substrate B for each substrate type BT1 to BT6 by the target production number of substrate B in the three mounting machines 2: the first mounting machine 2A, the second mounting machine 2B, and the third mounting machine 2C. 【0075】 The mounting position determination unit 12 adjusts the number of feeders to be consolidated for each of the three individual feeder groups FGB1, FGB2, FGB3, FGB4, FGB5, and FGB6, within a range where the working time WT for the replacement work is less than or equal to the production time PTT for the substrate B, when consolidating the three feeders 25 belonging to each individual feeder group into a portion of the three mounting machines 2. 【0076】 In other words, the mounting position determination unit 12 adjusts the number of aggregated feeders when aggregating the three feeders 25 belonging to the first individual feeder group FGB1 and the fourth individual feeder group FGB4 around the first mounting machine 2A, within a range where the work time WT for the exchange work between the first individual feeder group FGB1 and the fourth individual feeder group FGB4 during the switching period SP between substrate type BT1 and substrate type BT2 is less than or equal to the production time PTT for substrate B of substrate type BT1. In this case, by adjusting the number of aggregated feeders relative to the first mounting machine 2A to three for each of the three feeders 25 belonging to the first individual feeder group FGB1 and the fourth individual feeder group FGB4, the work position for the exchange work between the first individual feeder group FGB1 and the fourth individual feeder group FGB4 becomes only the first mounting machine 2A, making it possible to improve the work efficiency of the exchange work. On the other hand, in the three feeders 25 belonging to the first individual feeder group FGB1 and the fourth individual feeder group FGB4, respectively, as shown in Figures 9 and 10, by adjusting the number of aggregated feeders to the first mounting machine 2A to two and the remaining one to the second mounting machine 2B adjacent to the first mounting machine 2A, it becomes possible to improve the productivity of substrate B of substrate type BT1 by gently distributing the mounting positions of the three feeders 25 belonging to the first individual feeder group FGB1 and the fourth individual feeder group FGB4 relative to the first mounting machine 2A and the second mounting machine 2B, within a range where the work time WT for replacement work is less than or equal to the production time PTT. 【0077】 Furthermore, the mounting position determination unit 12 adjusts the number of aggregated feeders when aggregating the three feeders 25 belonging to the second individual feeder group FGB2 and the fifth individual feeder group FGB5, centered around the second mounting machine 2B, within a range where the work time WT for the exchange work between the second individual feeder group FGB2 and the fifth individual feeder group FGB5 during the switching period SP between substrate type BT2 and substrate type BT3 is less than or equal to the production time PTT for substrate B of substrate type BT2. In this case, by adjusting the number of aggregated feeders for the second mounting machine 2B to three for each of the three feeders 25 belonging to the second individual feeder group FGB2 and the fifth individual feeder group FGB5, the work position for the exchange work between the second individual feeder group FGB2 and the fifth individual feeder group FGB5 becomes limited to the second mounting machine 2B, thereby increasing the work efficiency of the exchange work. On the other hand, in the three feeders 25 belonging to the second individual feeder group FGB2 and the fifth individual feeder group FGB5, respectively, as shown in Figures 9 and 10, by adjusting the number of aggregating feeders to the second mounting machine 2B to two and the remaining one to the first mounting machine 2A adjacent to the second mounting machine 2B, it becomes possible to improve the productivity of substrate B of substrate type BT2 by gently distributing the mounting positions of the three feeders 25 belonging to the second individual feeder group FGB2 and the fifth individual feeder group FGB5 relative to the second mounting machine 2B and the first mounting machine 2A, within a range where the work time WT for replacement work is less than or equal to the production time PTT. 【0078】 Furthermore, the mounting position determination unit 12 adjusts the number of aggregated feeders when aggregating the three feeders 25 belonging to the third individual feeder group FGB3 and the sixth individual feeder group FGB6 around the third mounting machine 2C, within a range where the work time WT for the exchange work between the third individual feeder group FGB3 and the sixth individual feeder group FGB6 during the switching period SP between substrate type BT3 and substrate type BT4 is less than or equal to the production time PTT for substrate B of substrate type BT3. In this case, by adjusting the number of aggregated feeders relative to the third mounting machine 2C to three for each of the three feeders 25 belonging to the third individual feeder group FGB3 and the sixth individual feeder group FGB6, as shown in Figure 11, the work position for the exchange work between the third individual feeder group FGB3 and the sixth individual feeder group FGB6 becomes limited to the third mounting machine 2C, thereby increasing the work efficiency of the exchange work. On the other hand, by adjusting the number of aggregated feeders for the third mounting machine 2C to be reduced, in the case of the three feeders 25 belonging to the third individual feeder group FGB3 and the sixth individual feeder group FGB6, respectively, it is possible to improve the productivity of substrate B of substrate type BT3 by gently distributing the mounting positions of the three feeders 25 belonging to the third individual feeder group FGB3 and the sixth individual feeder group FGB6 to the third mounting machine 2C and the adjacent second mounting machine 2B, within a range where the working time WT for replacement work is less than or equal to the production time PTT.
