Abstract

To more efficiently distribute food through a feeder.SOLUTION: A management device is used in a component mounting system that includes a component mounting machine having a supply mount portion and a buffer mount portion. When a target feeder to be used in a target job to be executed next or later is pre-distributed to the component mounting machine, the management device determines a delivery destination by giving priority to an empty slot of the buffer mount portion out of an empty slot of the supply mount portion and an empty slot of the buffer mount portion, and controls a working device to pre-distribute the target feeder to the determined delivery destination.SELECTED DRAWING: Figure 8

Description

[Technical field]

[0001] This specification discloses a management device, a management method, and a work device used in a component mounting system. [Background technology]

[0002] Conventionally, a mounting system has been proposed that includes a component mounter including a plurality of mounting receptacles (slots) to which feeders are attached and a mounting section that picks up and mounts components from the feeders attached to the mounting receptacles, and a mobile work device that retrieves the feeders from the mounting receptacles and arranges the feeders to the mounting receptacles (see, for example, Patent Document 1). The component mounter further has a buffer receptacle for temporarily storing the feeders. The mobile work device pre-arranges feeders to be used in the next and subsequent production runs to vacant mounting receptacles or vacant buffer receptacles.

[0003] [Patent Document 1] International Publication No. 2020 / 039544 Summary of the Invention [Problem to be solved by the invention]

[0004] When feeders are pre-arranged to the empty mounting sections, the pre-arrangement is not necessarily performed in the order of earliest use. For example, when it is predicted that some feeders will run out of parts during production, spare feeders containing the same types of parts may be arranged in the empty mounting sections (empty slots) in order to avoid interruptions to production as much as possible. In this case, when many feeders to be used in the next and subsequent productions are attached to the mounting sections and there are no free mounting sections, the mobile work device must first remove the feeders that will not be used in the current production from the mounting sections and then attach the spare feeders to be used in the current production. For this reason, in the conventional method, the arrangement work takes time, and there are cases in which the arrangement of feeders is not efficient.

[0005] The primary objective of the present disclosure is to make feeder distribution more efficient. [Means for solving the problem]

[0006] In order to achieve the above-mentioned main object, the present disclosure has adopted the following means.

[0007] The management device of the present disclosure includes: a component mounter having a supply mount section including a plurality of slots in which feeders are mounted, a buffer mount section including a plurality of slots in which the feeders are mounted, and a mount section that executes a mount job of picking up components supplied from the feeders mounted in the slots of the supply mount section and mounting the components; an operating device capable of performing a feeding operation and a recovery operation of the feeder for each slot of the supply mounting portion and each slot of the buffer mounting portion; A management device for use in a component mounting system comprising: a management control unit that, when a target feeder to be used in a target job to be executed next or later is pre-arranged to the component mounter, determines a destination by giving priority to an empty slot of the buffer mount part out of an empty slot of the supply mount part and an empty slot of the buffer mount part, and controls the work device to pre-arrange the target feeder to the determined destination; The gist of the invention is to provide the following:

[0008] The management device disclosed herein is used in a component mounting system including a component mounter having a supply mount and a buffer mount. When a target feeder to be used in a target job to be executed next or later is pre-arranged to the component mounter, the management device pre-arranges the target feeder to a destination that prioritizes the free slot of the target feeder in the supply mount and the free slot of the buffer mount. This allows the feeder to be pre-arranged to the component mounter while securing a free slot in the supply mount. Therefore, even if a feeder with a higher priority than the target feeder needs to be arranged to the supply mount after the target feeder is pre-arranged, there is no need to remove the already-mounted feeder. This makes it possible to avoid unnecessary removal of the feeder and to arrange the feeder more efficiently. [Brief description of the drawings]

[0010] Next, an embodiment of the present disclosure will be described with reference to the drawings.

[0011] FIG. 1 is a schematic diagram of a component mounting system. FIG. 2 is a schematic diagram of a component mounter and a feeder table. FIG. 3 is a schematic diagram of a feeder. FIG. 4 is a schematic diagram of a loader. FIG. 5 is a block diagram showing the electrical connection relationship of the component mounting system. In FIG. 1, 2, and 4, the left-right direction is the X-axis direction, the front-back direction is the Y-axis direction, and the up-down direction is the Z-axis direction.

[0012] The component mounting system 10 produces a board S on which components are mounted, and includes, as shown in FIG. 1, a printing device 12, a print inspection device 14, a plurality of component mounters 20 (201-206), a mounting inspection device (not shown), a loader 50, a feeder storage 60, and a management device 80 that manages the entire system. The printing device 12 prints solder on the surface of the board S. The print inspection device 14 inspects the state of the solder printed by the printing device 12. The component mounter 20 picks up components supplied from the feeder 30 with a suction nozzle (picking member) and mounts them on the board S. The mounting inspection device inspects the mounting state of the components mounted by the component mounter 20. The printing device 12, the print inspection device 14, the plurality of component mounters 20, and the mounting inspection device are aligned in this order from upstream along the transport direction of the board S to form a production line.

[0013] 2, the component mounter 20 includes a mounting unit 21 on which the feeder 30 is mounted, a board transport device 22 that transports the board S in the X-axis direction, a head 25 that picks up components from the feeder 30 and mounts them on the board S, a head moving device 24 that moves the head 25 in the horizontal direction (X-axis and Y-axis directions), and a mounting control device 29 (see FIG. 5). Although not shown, the head 25 has a suction nozzle that picks up the components and a lifting device that raises and lowers the suction nozzle. The head moving device 24 has a slider 24a to which the head 25 is attached, and moves the slider 24a in the horizontal direction (X-axis and Y-axis directions).

[0014] As shown in FIG. 3, the feeder 30 is a cassette-type tape feeder, and includes a tape reel 32, a tape feeding mechanism 33, a connector 35, and a feeder control device 39 (see FIG. 5). A tape containing components is wound around the tape reel 32. The components are protected by a film covering the surface of the tape. The tape feeding mechanism 33 pulls out the tape from the tape reel 32 and feeds it to a component supply position. The components contained in the tape are exposed at the component supply position by peeling off the film just before the component supply position, and are picked up by the head 25 (suction nozzle). The feeder control device 39 is composed of a known CPU, ROM, RAM, etc., and outputs a drive signal to the tape feeding mechanism 33 (feed motor).

[0015] The mounting section 21 is provided on the front side (front part) of the component mounter 20, and has two areas, an upper area and an lower area, in which the feeder 30 can be set. The upper area is a supply area 21A in which the feeder 30 can supply components to a position (component supply position) from which the head 25 can pick up components, and the lower area is a buffer area 21B in which the feeder 30 is temporarily stored. A feeder table 40 is installed in each of the areas 21A and 21B. As shown in FIG. 2, the feeder table 40 in each of the areas 21A and 21B has a plurality of slots 42 in which the feeder 30 is attached and detached, and a plurality of connectors 45 that are electrically connected to the connectors 35 of the feeder 30 attached to the corresponding slots 42. The feeder 30 containing components to be used in the job (production) being executed is attached to the supply area 21A. Furthermore, if there is an empty slot 42 in the supply area 21A, a spare feeder 30 for supplying the same type of parts in place of a feeder 30 that has run out of parts during production, or a feeder 30 storing parts to be used in a job to be executed next or later, etc. may be installed in the buffer area 21B. The buffer area 21B is used to temporarily store feeders 30 storing parts to be used in a job to be executed next or later, or to temporarily store used feeders 30.

[0016] The component mounter 20 also includes a mark camera 26 and a parts camera 27. The mark camera 26 captures an image of a reference mark attached to the board S from above in order to detect the position of the board S. The parts camera 27 captures an image of a component picked up by the suction nozzle from below in order to detect suction errors and suction deviations.

[0017] The mounting control device 29 is composed of a known CPU 29a, ROM 29b, HDD 29c, RAM 29d, etc. The mounting control device 29 inputs image signals and the like from the mark camera 26 and the parts camera 27. In addition, the mounting control device 29 outputs drive signals to the board transport device 22, the head 25, the head moving device 24, etc.

[0018] The mounting control device 29 is also communicatively connected to a feeder control device 39 of the feeder 30 mounted on the feeder table 40 via connectors 35, 45. When the feeder 30 is mounted, the mounting control device 29 receives feeder information such as the feeder ID, component type, and remaining component count contained in the feeder control device 39 of the feeder 30 from the feeder control device 39. The mounting control device 29 also transmits the received feeder information and the mounting position (slot number) at which the feeder 30 is mounted to the management device 80.

[0019] The CPU 29a of the mounting control device 29 executes a mounting process for mounting a component on the board S. The CPU 29a moves the head 25 to above the component supply position of the feeder 30 by the head moving device 24. Next, the CPU 29a lowers the suction nozzle by the lifting device to have the component sucked by the suction nozzle. The CPU 29a moves the component sucked by the suction nozzle to above the part camera 27 by the head moving device 24, and captures an image of the component by the part camera 27. The CPU 29a processes the captured image of the component to measure the amount of suction deviation of the component, and corrects the mounting position of the component on the board S. Then, the CPU 29a moves the component sucked by the nozzle to above the corrected mounting position by the head moving device 24, and lowers the suction nozzle by the lifting device to mount the component on the board S.

[0020] The feeder storage 60 is incorporated into the production line and is a storage location for temporarily storing a plurality of feeders 30. A feeder table having a plurality of slots 42 and connectors 45 similar to those of the feeder table 40 of the component mounter 20 is installed in the feeder storage 60. The feeder storage 60 is replenished with feeders 30 to be used and used feeders 30 are collected by an automatic guided vehicle (AGV) (not shown) or an operator. When the feeder 30 is attached to the connector 45 of the feeder storage 60, feeder information such as the feeder ID, component type, and remaining number of components included in the feeder 30, and the attachment position (slot number) where the feeder 30 is attached are transmitted to the management device 80.

[0021] As shown in Fig. 1, the loader 50 moves along the line in front of the component mounting system 10 (production line), takes out feeders 30 to be used from a feeder storage 60 and supplies them to each component mounter 20, or collects used feeders 30 from each component mounter 20 and carries them to the feeder storage 60. As shown in Fig. 4, the loader 50 includes a loader moving device 51, a feeder transfer device 53, and a loader control device 59 (see Fig. 5). The loader moving device 51 moves the loader 50 along a guide rail 18 arranged in front of the production line. The loader moving device 51 includes an X-axis motor 52a that drives a drive belt for moving the loader 50, and a guide roller 52b that rolls on the guide rail 18 to guide the movement of the loader 50. The feeder transfer device 53 transfers the feeder 30 between the component mounter 20 and the loader 50 when the loader 50 faces one of the component mounters 20, or transfers the feeder 30 between the feeder storage 60 and the loader 50 when the loader 50 faces the feeder storage 60. The feeder transfer device 53 has a Y-axis slider 55 and a Z-axis motor 56a that moves the Y-axis slider 55 along the Z-axis guide rail 56b. The Y-axis slider 55 includes a clamping section 54 that clamps the feeder 30, and a Y-axis motor 55a that moves the clamping section 54 along the Y-axis guide rail 55b. The Y-axis slider 55 moves up and down by being driven by the Z-axis motor 56a. Feeder transfer device 53 raises Y-axis slider 55 so that Y-axis slider 55 faces feeder table 40 in supply area 21A of component mounter 20 or feeder table 40 in feeder storage 60, and in this state clamps feeder 30 with clamp unit 54 and moves it in the Y-axis direction by Y-axis slider 55, thereby transferring feeder 30 to supply area 21A or feeder storage 60. Feeder transfer device 53 also lowers Y-axis slider 55 so that Y-axis slider 55 faces buffer area 21B of component mounter 20, and in this state clamps feeder 30 with clamp unit 54 and moves it in the Y-axis direction by Y-axis slider 55, thereby transferring feeder 30 to buffer area 21B.The loader control device 59 is composed of a well-known CPU, ROM, RAM, etc., and inputs signals from a position sensor 57 that detects the traveling position and a monitoring sensor 58 that detects the presence or absence of obstacles in the vicinity, and outputs drive signals to the loader moving device 51 and the feeder transfer device 53.

[0022] The management device 80 is a general-purpose computer, and includes a CPU 81, a ROM 82, a HDD 83 (storage device), and a RAM 84, as shown in FIG. 5. An input device 85 such as a keyboard and a mouse, and a display 86 are electrically connected to the management device 80. In addition to the production schedule, the HDD 83 stores various information required for production, such as feeder holding information, job information, and status information. These pieces of information are managed for each component mounter 20. Here, the production schedule is a schedule that determines which components are to be mounted on which board S in which order in each component mounter 20, and how many boards S (products) mounted in this way are to be manufactured. The feeder holding information is information about the feeders 30 held by each component mounter 20 and the feeder storage 60. As shown in FIG. 6, the feeder holding information includes feeder information such as a feeder ID, a component type, and the number of remaining components, and position information such as a device (location) holding the feeder 30 (component) and a mounting position (slot number) of the feeder 30. The job information is information about a mounting process (job) to be executed by each mounter 20. This job information includes the type of board to be produced, the type of component to be mounted, the mounting position for each component, and the placement position (placement position information) of the component to be placed in the supply area 21A for each job. The placement position information of the component indicates the planned placement position (planned slot) of the feeder 30 that accommodates the component, and is managed for each mounter 20. As shown in FIG. 7, the placement position information is stored in association with the execution order of the job and the type of component to be placed for each slot 42 in the supply area 21A. The status information is information that indicates the operation status of each mounter 20. This status information includes in production, in changeover, and in abnormality.

[0023] The management device 80 is connected to the mounting control device 29 by wire so as to be able to communicate with each mounter 20 of the component mounting system 10, and exchanges various information with each mounter 20. The management device 80 receives operation status from each mounter 20 and updates the status information to the latest information. The management device 80 is also connected to the feeder control device 39 of the feeder 30 attached to the feeder table 40 of each mounter 20 via the mounting control device 29 so as to be able to communicate with each other. When the feeder 30 is removed from the mounter 20 or the feeder storage 60, or when the feeder 30 is attached to the mounter 20 or the feeder storage 60, the management device 80 receives the attachment / detachment status from the corresponding mounter 20 or the feeder storage 60, and updates the feeder holding information to the latest information. The management device 80 is also connected to the loader control device 59 by wireless so as to be able to communicate with each other, and exchanges various information with the loader 50. Furthermore, the management device 80 is communicably connected to the control devices of the printing device 12, the print inspection device 14, and the mounting inspection device, and also exchanges various types of information with the corresponding devices.

[0024] Next, the operation of the component mounting system 10 thus configured will be described. In particular, the operation when pre-arranging components (feeders 30 containing those components) to be used in jobs to be executed from the next time onwards will be described. Fig. 8 is a flow chart showing an example of a loader operation instruction routine executed by the CPU 81 of the management device 80. This routine is repeatedly executed at predetermined time intervals.

[0025] When the loader work instruction routine is executed, the CPU 81 first refers to the feeder holding information shown in Fig. 6 to determine whether or not the feeder storage 60 contains parts (feeders 30 containing those parts) to be used in jobs to be executed from the next time onwards (S100). If the CPU 81 determines that there are no applicable parts, it proceeds to S240. On the other hand, if the CPU 81 determines that there are applicable parts, it sets the parts to be distributed this time from among the applicable parts (S110).

[0026] Next, the CPU 81 judges whether or not the scheduled slot of the part to be distributed is available (S120). The scheduled slot is the placement position (slot number) in the supply area 21A where the part used in the job should be placed, and is determined in advance by an optimization program so that the execution of the job using the part is optimized. The judgment in S120 is performed by reading the scheduled slot of the part to be distributed from the part placement information shown in FIG. 7, and judging whether or not another part (feeder 30) is attached to the read scheduled slot based on the feeder possession information shown in FIG. 6. When the CPU 81 judges that the scheduled slot of the part to be distributed is available, it sets the destination of the part to be distributed to the scheduled slot of the part to be distributed (S130).

[0027] When the CPU 81 determines that there is no vacancy in the scheduled slot of the target part, it determines whether there is vacancy in the buffer area 21B of the target component mounter (own machine), which is the component mounter 20 to which the target part is to be delivered, based on the feeder possession information (S140). When the CPU 81 determines that there is vacancy in the buffer area 21B of its own machine, it sets the delivery destination of the target part to any of the vacant slots in the buffer area 21B of its own machine (S150). Note that when there are multiple vacant slots in the buffer area 21B of its own machine, the CPU 81 may set the delivery destination to the vacant slot closest to the scheduled slot of the target part among the multiple vacant slots.

[0028] When the CPU 81 determines that there is no vacant space in the buffer area 21B of the own machine, it determines whether there is vacant space in the supply area 21A of the own machine based on the feeder possession information (S160). When the CPU 81 determines that there is vacant space in the supply area 21A of the own machine, it sets the delivery destination of the part to be distributed to any vacant slot in the supply area 21A of the own machine other than the scheduled slot described above (S170). Note that when there are multiple vacant slots in the supply area 21A of the own machine, the CPU 81 may set the delivery destination to the vacant slot closest to the scheduled slot of the part to be distributed among the multiple vacant slots.

[0029] When the CPU 81 determines that there is no vacant space in the supply area 21A of its own machine, it determines whether there is vacant space in the buffer area 21B of the non-target component mounter (other machine), which is the component mounter 20 that is not the delivery destination of the delivery target component, based on the feeder possession information (S180). When the CPU 81 determines that there is vacant space in the buffer area 21B of the other machine, it sets the delivery destination of the delivery target component to any of the vacant slots in the buffer area 21B of the other machine that is closest to its own machine (S190). Note that when there are multiple vacant slots in the corresponding buffer area 21B, the CPU 81 may set the delivery destination to the vacant slot that is closest to the scheduled slot of the delivery target component among the multiple vacant slots.

[0030] When the CPU 81 determines that there is no vacant space in the buffer area 21B of the other machine, it determines whether there is vacant space in the supply area 21A of the other machine based on the feeder holding information (S200). When the CPU 81 determines that there is vacant space in the supply area 21A of the other machine, it sets the delivery destination of the target part to any of the vacant slots in the supply area 21A of the other machine that is closest to the own machine (S210). Note that, when there are multiple vacant slots in the corresponding supply area 21A, the CPU 81 may set the vacant slot that is closest to the scheduled slot of the target part among the multiple vacant slots as the delivery destination. On the other hand, when the CPU 81 determines that there is no vacant space in the supply area 21A of the other machine, it proceeds to S240 without setting the delivery destination of the target part.

[0031] When the CPU 81 sets the delivery destination of the delivery target parts in this way, it judges whether there are other parts whose delivery destinations have not been determined among the parts corresponding to S100 (S220). When the CPU 81 judges that there are other parts whose delivery destinations have not been determined, it returns to S110 and repeats the process of S110 to S210 to set the next delivery target part from among the corresponding parts and set its delivery destination. On the other hand, when the CPU 81 judges that there are no other parts whose delivery destinations have not been determined, it transmits a delivery command to the loader 50 so that each delivery target part (the feeder 30 containing each delivery target part) is delivered in advance to the delivery destinations set respectively (S230). The loader 50 that has received the delivery command delivers the delivery target parts (the feeder 30 containing the delivery target parts) to the specified delivery destinations.

[0032] Next, the CPU 81 judges whether or not there is a component pre-arranged in a slot other than the scheduled slot of the component of the component that is arranged in the supply area 21A and the buffer area 21B of each mounter 20 (S240). If the CPU 81 judges that there is a component pre-arranged in another slot, it judges whether or not the preceding job using the other component whose scheduled slot overlaps with the component of the component has ended (S250). If the CPU 81 judges that there is no component pre-arranged in a slot other than the scheduled slot or that the preceding job using the component whose scheduled slot overlaps has not ended, it ends this routine.

[0033] On the other hand, when the CPU 81 determines that there is a part pre-arranged in a slot other than the scheduled slot and that the preceding job using the part with which the scheduled slot overlaps has ended, it sets the corresponding part as a part to be moved and sets the destination of the part to be moved to the scheduled slot of the part to be moved, specifies the destination and transmits a placement command (movement command) to the loader 50 (S260), and ends this routine. The loader 50 that receives the movement command collects the used part (feeder 30) used in the preceding job from the scheduled slot and arranges the part to be moved to the scheduled slot. As described above, when there is no vacancy in the scheduled slot of the part itself, the part itself is pre-arranged in an empty slot other than the original scheduled slot. The process of S260 is a process for collecting the used part and moving the part itself to the original scheduled slot when the preceding job ends and the part with which the part itself overlaps has become used. As described above, since the part not arranged in the original scheduled slot is arranged in a slot as close as possible to the scheduled slot, the movement amount of the part can be reduced when the part is moved. This enables the loader 50 to quickly perform the work of moving parts.

[0034] FIG. 9 is an explanatory diagram showing the priority order of pre-distribution locations of components (feeders). In the figure, among six component mounters 201-206, component mounter 203 indicates a target component mounter (own machine), and component mounters 201, 202, 204-206 indicate non-target component mounters (other machines). Pre-distribution of the target components is performed by checking for empty slots in descending order of priority according to a predetermined priority order, and determining the found empty slot as the distribution destination. As shown in the figure, the priority order is determined in the order of scheduled slots of the target components, buffer area 21B of the own machine, supply area 21A other than the scheduled slot of the own machine, buffer area 21B of the other machine, and supply area 21A of the other machine. The closer the buffer area 21B of the other machine is to the own machine, the higher the priority order is set. The closer the supply area 21A of the other machine is to the own machine, the higher the priority order is set. As a result, the parts to be distributed are pre-distributed in the scheduled slots if the scheduled slots are available. Furthermore, the parts to be distributed are pre-distributed in the available slots in the buffer area 21B of the own machine if the scheduled slots are not available. Furthermore, the parts to be distributed are pre-distributed in the available slots other than the scheduled slots in the supply area 21A of the own machine if the buffer area 21B of the own machine is not available. Furthermore, the parts to be distributed are pre-distributed in the available slots in the buffer area 21B of the other machine that is as close to the own machine as possible if the supply area 21 of the own machine is not available. Furthermore, the parts to be distributed are pre-distributed in the available slots in the supply area 21A of the other machine that is as close to the own machine as possible if the buffer areas 21B of none of the other machines are available.

[0035] Here, in this embodiment, when a part shortage is predicted while a job is being executed using the parts arranged in the supply area 21A, a spare feeder 30 containing the same kind of parts is arranged in an empty slot in the supply area 21A. As a result, even if a part of the feeders 30 runs out of parts during execution of a job, the component mounter 20 can avoid interrupting the job by picking up parts from the spare feeder 30. However, if a large number of parts to be used in the next or subsequent jobs are arranged in the supply area 21A, there may be a case where there is no space in the supply area 21A when distributing the spare feeder 30. In this case, the loader 50 must first remove the feeder 30 that is not used in the current job and is blocking the supply area 21A, and then mount the spare feeder 30 used in the current job in the empty slot 42, which results in a wasteful removal work. In this embodiment, when parts (distribution target parts) to be used in the next or subsequent jobs are pre-distributed, the destination of the distribution target parts is set to the buffer area 21B with priority over the supply area 21A and the buffer area 21B of the machine itself. This allows an empty slot to be secured in the supply area 21A of the machine itself. Therefore, even if it becomes necessary to later distribute a feeder 30 having a high priority to the supply area 21A, the time required for the distribution work of the feeder 30 can be shortened, and the distribution of the feeder 30 can be performed efficiently.

[0036] Here, the correspondence between the main elements of this embodiment and the main elements described in the claims will be described. That is, the multiple slots 42 of the supply area 21A of this embodiment correspond to the multiple slots of this disclosure, the component mounter 20 corresponds to the component mounter, the loader 50 corresponds to the work device, and the CPU 81 that executes the loader work instruction routine corresponds to the management control unit. The buffer area 21B corresponds to the buffer.

[0037] It goes without saying that the present disclosure is in no way limited to the above-described embodiment, and can be embodied in various forms as long as it falls within the technical scope of the present disclosure.

[0038] For example, in the above embodiment, when the CPU 81 pre-distributes the parts to be distributed in the supply area 21A or buffer area 21B of the other machine when there is no vacant space in either the supply area 21A or buffer area 21B of the own machine, the CPU 81 pre-distributes the parts to be distributed in the supply area 21A or buffer area 21B of the other machine. However, the CPU 81 may not pre-distribute the parts to be distributed in the supply area 21A or buffer area 21B of the own machine when there is no vacant space in either the supply area 21A or buffer area 21B of the own machine.

[0039] As described above, the management device of the present disclosure is a management device used in a component mounting system including a component mounting machine having a supply mounting part including a plurality of slots to which feeders are attached, a buffer mounting part including a plurality of slots to which the feeders are attached, and a mounting part that executes a mounting job to remove and mount components supplied from the feeders attached to the slots of the supply mounting part, and a work device capable of performing distribution and recovery operations of the feeder for each slot of the supply mounting part and each slot of the buffer mounting part, and is provided with a management control unit that, when a target feeder to be used in a target job to be executed next or later is pre-distributed to the component mounting machine, gives priority to the empty slot of the buffer mounting part out of the empty slots of the supply mounting part and the buffer mounting part as a distribution destination, and controls the work device to pre-distribute the target feeder to the determined distribution destination.

[0040] In the management device disclosed herein, it is possible to secure an empty slot in the supply mounting section while pre-arranging a feeder in the component mounter. Therefore, even if it becomes necessary to arrange a feeder with a higher priority than the target feeder in the supply mounting section after the target feeder has been pre-arranged, it is not necessary to remove the already-attached feeder. Therefore, it is possible to avoid unnecessary feeder removal work and perform feeder arrangement more efficiently.

[0041] In the management device of the present disclosure, the management control unit may control the operation device to pre-distribute the target feeder to the scheduled slot of the target feeder when the scheduled slot to which the target feeder is scheduled to be delivered is available. Pre-distributing the target feeder to the scheduled slot can eliminate the need to move the target feeder when executing a job that uses the target feeder.

[0042] In addition, in the management device of the present disclosure, the component mounting system includes a mounting line on which a plurality of the component mounters are arranged, the operation device is capable of performing the feeder placement and collection operations for each component mounter on the mounting line, and when the target feeder is pre-placed and there is no vacancy in either the supply mounting portion or the buffer mounting portion of the target component mounter that is the component mounter that executes the target job, the management control unit may control the operation device to determine the supply mounting portion or the buffer mounting portion of another component mounter that is different from the target component mounter among the plurality of component mounters that make up the mounting line as the placement destination and pre-place the target feeder to the determined placement destination. In this way, the target feeder can be pre-placed even when there is no vacancy in either the supply mounting portion or the buffer mounting portion of the target component mounter. In this case, when the target feeder is pre-arranged, if there is no vacancy in either the supply mounting portion or the buffer mounting portion of the target component mounter, the management control unit may determine the destination of the feeder by giving priority to the vacant slot of the buffer mounting portion among the vacant slots of the supply mounting portion and the vacant slots of the buffer mounting portion of the other component mounter. In this way, it is possible to secure the vacant slot of the supply mounting portion of the other component mounter. Therefore, even if it becomes necessary to arrange a feeder having a higher priority than the target feeder to the supply mounting portion of the other component mounter after the target feeder is pre-arranged, it is not necessary to remove the already-mounted feeder. Therefore, it is possible to avoid unnecessary feeder removal work and arrange the feeder more efficiently. In these cases, when the target feeder is pre-arranged, if there is no vacancy in either the supply mounting portion or the buffer mounting portion of the target component mounter, the management control unit may determine the destination of the feeder by giving priority to the component mounter closer to the target component mounter among the other component mounters. In this way, even if the target component mounter that uses the target feeder is not available, the target feeder can be pre-arranged.In addition, since the amount of movement required when moving a target feeder that has been pre-distributed to its scheduled slot can be reduced, the changeover work can be completed in a shorter time.
