Description

  The present invention relates to an assignment device, a production system, an assignment method, and a program used in an assignment device for assigning a feeder to a feeder bank of a mounting device.

  Generally, in a component mounting apparatus, a plurality of feeders are arranged side by side on an arrangement table called a feeder bank. Various components are sequentially sent from each feeder to the pickup position of the mounting head, and the components are mounted on the board by moving the mounting head between each feeder and the board. By the way, the assignment of the feeder to the feeder bank is determined according to the production program for each board inputted to the host computer as the assignment device. The feeder mounted on the board is specified in the production program for each board, and the feeder used for each production program is different.

  2. Description of the Related Art Conventionally, a method of allocating a feeder capable of efficiently executing a plurality of production programs has been known (for example, see Patent Document 1). In the method of allocating a feeder described in Patent Document 1, after a plurality of production programs are registered in a reservation file of a host computer and clustered as one program, the same cluster is used even if the substrate is changed and the production program is changed. In this example, the feeder assignment is optimized so that the work of replacing the feeder does not occur. The optimized reservation file is notified from the host computer to the mounting apparatus, and the feeder is attached to the feeder bank in accordance with the feeder arrangement of the reservation file before the operation of the mounting apparatus.

  According to the feeder allocation method described in Patent Literature 1, each feeder used in a plurality of production programs can be efficiently allocated to each cluster of the reservation file. However, if it is necessary to add a new production program to the optimized reservation file (cluster) due to a change in the production plan, etc., the feeder arrangement of the reservation file is re-optimized and changes significantly from the existing feeder arrangement Could be As a result, there is a problem that the arrangement of the feeders in the feeder bank is changed and replacement work of the feeders occurs, and the number of work steps increases, and the work load of the operator increases.

  The present invention has been made in view of the above, and is used in an allocating apparatus, a production system, an allocating method, and an allocating apparatus capable of optimally allocating a feeder when a new production program is added without increasing an operator's work load. The purpose is to provide a program that can be used.

The allocating device of the present invention is an allocating device that allocates a feeder used in the production program to a feeder bank of a mounting device that mounts components supplied from the feeder on the substrate based on the production program, and A storage unit storing a reservation file including a cluster obtained by integrating a plurality of different production programs, and an allocating unit allocating a feeder used in the plurality of production programs to the feeder bank for each of the clusters, When a new production program is added to the file, the allocating unit assigns priority to the feeder arrangement of the existing cluster , allocates a feeder used in the new production program to the feeder bank, and The new production program is stored in the feeder bank in which the feeder arrangement is set. A determining unit that determines whether a feeder to be used can be allocated; and if the determining unit determines that the feeder used in the new production program cannot be allocated, the new file is added to the reservation file. A new cluster is generated for a production program, the new production program is added to the new cluster, and the allocating unit changes the feeder arrangement of the existing cluster and the new cluster to a feeder of the existing cluster. It is characterized in that reassignment is performed so as to minimize the change in arrangement .

An allocation method according to the present invention is an allocation method for allocating a feeder used in a production program to a feeder bank of a mounting apparatus that mounts components supplied from a feeder on a board based on a production program, and Generating a cluster in which a plurality of different production programs are integrated for each type of substrate, and allocating a feeder used in the plurality of production programs to the feeder bank for each of the clusters. In the step of allocating to the feeder bank, when a new production program is added to the reservation file, a feeder used in the new production program is allocated to the feeder bank by giving priority to a feeder arrangement of an existing cluster. The feeder arrangement of the existing cluster is set The feeder bank further includes a step of determining whether or not a feeder used in the new production program can be assigned, and in the determining step, the feeder used in the new production program cannot be assigned. If it is determined, a new cluster is generated in the reservation file for the new production program, the new production program is added to the new cluster, and the assigning step includes: Is re-assigned to minimize the change of the feeder arrangement of the existing cluster .

According to these configurations, even if a new production program is added to an existing cluster in the reservation file, the feeder arrangement of the existing cluster has priority. Therefore, the feeders used in the new production program can be assigned to the feeder banks without significantly changing the feeder arrangement with respect to the current feeder banks. The work of replacing the feeder can be minimized, and the work load on the operator can be reduced. In this way, feeders can be assigned to feeder banks in consideration of the operator's workload. Further, by replacing the feeder bank to which the feeders of the existing cluster are attached with the feeder bank to which the feeders of the new cluster are attached, the work load on the operator can be reduced. Further, even when a new production program is added to a new cluster, it is possible to minimize the work of replacing an operator when switching from an existing cluster to a new cluster, thereby reducing the work load.

  In the above-mentioned allocating device, a search unit is provided for searching the reservation file for an existing cluster that uses at least one of the same feeders as the new production program, and the new cluster is searched for in the existing cluster searched by the search unit. The program is added. According to this configuration, since the feeders used in the existing cluster are also used in the new production program, the increase in the number of feeders due to the addition of the new production program can be minimized.

  In the above-mentioned allocation device, the feeder bank in which the feeder arrangement of the existing cluster is set, further includes a determination unit that determines whether a feeder used in the new production program can be allocated, and the determination unit includes: When it is determined that the feeders used in the new production program can be assigned, the allocating unit replaces the feeders used in the new production program with the feeders without changing the feeder arrangement of the existing clusters. Assign to bank. According to this configuration, the feeders used in the new production program can be assigned to the feeder banks without changing the feeder arrangement of the existing cluster.

  A production system according to the present invention includes the allocating device described above and a mounting device having a feeder bank to which a feeder is allocated by the allocating device. According to this configuration, a feeder can be assigned to the feeder bank of the mounting apparatus in consideration of the work load of the operator.

  Hereinafter, a production system according to the present embodiment will be described with reference to the accompanying drawings. FIG. 1 is a schematic diagram of a production system according to the present embodiment. FIG. 2 is a diagram illustrating an example of feeder assignment according to a comparative example. In the following production system, a modular type mounting device will be described as an example, but the present invention is not limited to this, and can be appropriately changed. For example, the present invention is also applicable to a rotary type mounting device.

  As shown in FIG. 1, in a production system 1 according to the present embodiment, each mounting device 2 and a host computer 3 are connected by a wired or wireless connection, and a plurality of mounting devices 2 are integrally managed by a host computer 3. It is configured to be. Each mounting device 2 downloads a production program from the host computer 3 every time the substrate W to be mounted changes, and mounts components (not shown) supplied from a feeder (supply device) 4 on the substrate W based on the production program. I do. The production program is different for each type of the substrate W, and includes data on the mounting position of the component on the substrate W, the type of the component, the type of the feeder 4, and the like.

  At a substantially center of the base 21 of the mounting apparatus 2, a board transport unit 22 is provided along the X-axis direction. The board transport unit 22 carries in and positions the board W before component mounting below the mounting head 23 from one end in the X-axis direction, and unloads the board W after component mounting from the other end in the X-axis direction. Further, an exchange carriage 25 on which a feeder bank 24 is installed is connected to the mounting apparatus 2, and a number of feeders 4 are attached to the feeder bank 24 side by side along the substrate transport unit 22. The exchange trolley 25 can be separated from the mounting device 2, and a large number of feeders 4 can be replaced together with the feeder bank 24 at a time by exchanging the exchange trolley 25.

  A tape reel (not shown) is detachably mounted on the feeder 4, and a carrier tape in which a number of components are packaged is wound around the tape reel. The feeder 4 sequentially feeds out components toward a transfer position where the component is picked up by the mounting head 23 by rotation of the tape reel. At the transfer position of the mounting head 23, the cover tape on the surface is peeled off from the carrier tape, and components in the pocket of the carrier tape are exposed to the outside. The feeder 4 is not limited to a tape feeder, but may be any of a bulk feeder, a stick feeder, and a stack stick feeder.

  An XY moving unit 26 that moves the mounting head 23 in the X-axis direction and the Y-axis direction is provided on the base 21. The XY moving section 26 has a pair of Y-axis tables 27 extending in the Y-axis direction and an X-axis table 28 extending in the X-axis direction. The pair of Y-axis tables 27 are supported by supporting portions (not shown) provided at four corners of the base 21, and the X-axis table 28 is mounted on the pair of Y-axis tables 27 so as to be movable in the Y-axis direction. Have been. The mounting head 23 is mounted on the X-axis table 28 so as to be movable in the X-axis direction. The mounting head 23 is horizontally moved by the X-axis table 28 and the Y-axis table 27 so that the components picked up from the feeder 4 can be transferred onto the substrate W. At the desired position.

  In the production system 1 configured as described above, different production programs are registered in the host computer 3 for each substrate W according to a production plan, and a reservation file F (see FIG. 2) including a plurality of production programs is generated. The production program is read from the reservation file F into the mounting device 2, and components are mounted on the substrate W based on the production program. At this time, a cluster in which a plurality of production programs are integrated is set in the reservation file F, and the assignment of a large number of feeders 4 used in each production program to the feeder bank 24 is determined for each cluster.

  For example, as shown in FIG. 2A, when a plurality of production programs ae are registered as one cluster in the reservation file F, the arrangement of the feeders 4A-4E in the feeder bank 24 is optimized. That is, the components used in the production programs ae are selectively supplied from the feeders 4A-4E, and the layout of the feeders 4A-4E is determined so as to increase the line tact during the mounting process. Therefore, even if the production program is changed by switching the mounting target substrate W, the mounting process by the mounting apparatus 2 can be continued without the operator performing the work of replacing the feeder 4 within the same cluster. ing.

  By the way, as shown in FIG. 2B, when a new production program is added to the existing cluster of the reservation file F due to a change in the production plan or the like, the feeder 4X used only by the new production program is added to the feeder bank 24. There is a need to. In the host computer 3 (see FIG. 1), the assignment is determined in consideration of the line tact, so that the arrangement of the feeders 4A to 4E is automatically changed with the addition of the feeders 4X. For this reason, every time a new production program is added to an existing cluster, replacement work of the feeder 4 by the operator occurs, and the number of man-hours increases, and the operator's work load increases.

  Therefore, in the present embodiment, a new production program is added while giving priority to the feeder arrangement of the existing cluster in consideration of the operator's work load spent on the replacement work of the feeder 4. As a result, it is possible to add the feeders 4 used in the new production program to the feeder bank 24 without significantly affecting the current feeder arrangement. In the present embodiment, the host computer 3 is exemplified as the allocating device. However, the allocating device only needs to be capable of allocating a feeder used in the production program. It may be configured.

  Hereinafter, the detailed configuration of the host computer will be described with reference to FIG. FIG. 3 is a block diagram of the host computer according to the present embodiment. Note that the block diagram of the host computer shown in FIG. 3 is simplified for explaining the present invention, and it is assumed that the host computer has a configuration that is normally provided.

  As shown in FIG. 3, the host computer 3 determines the feeder arrangement for the feeder bank 24 of the mounting apparatus 2 according to a plurality of production programs, and includes a registration unit 31, an integration unit 32, an allocation unit 33, and a search unit 34. , A determination unit 35, a notification unit 36, and a storage unit 37. The registration unit 31 registers a plurality of different production programs for each type of the substrate W in the reservation file F of the storage unit 37. In this case, the reservation file F is generated by the dedicated application, and a plurality of production programs are registered in the reservation file F by the registration unit 31 by an input from the operator. Thereby, the mounting process based on the plurality of production programs is reserved in the reservation file F.

  The integration unit 32 integrates a plurality of production programs registered in the reservation file F as a cluster. In this case, when a predetermined number of production programs are registered in the reservation file F, these production programs are clustered so as to constitute one program. The cluster is set so that the mounting apparatus 2 can execute a plurality of production programs without rearranging or exchanging the feeders 4 even when the type of the substrate W changes. In the reservation file F, a plurality of production programs registered by the registration unit 31 are reserved in a clustered state. In this way, the storage unit 37 stores the reservation file F including the cluster obtained by integrating a plurality of production programs different for each type of the substrate W.

  The allocating unit 33 allocates the feeders 4 used in a plurality of production programs to the feeder bank 24 for each cluster of the reservation file F. For the production program of the existing cluster in the reservation file F, the allocation of the feeder 4 is determined in consideration of the line tact. For a new production program added to an existing cluster in the reservation file F due to a change in the production plan or the like, the allocation of the feeders 4 is determined by giving priority to the feeder arrangement of the existing cluster over the line tact. The details of the method of allocating the feeders 4 used in the new production program will be described later.

  When a new production program is added to the reservation file F, the search unit 34 searches the reservation file F for an existing cluster that uses the same feeder 4 as the new production program. Thus, since the feeders 4 used in the existing cluster are also used in the new production program, the increase of the feeders 4 due to the addition of the new production program is minimized. When the same feeder 4 as the new production program is searched for in a plurality of existing clusters, a cluster having a large number of common feeders is selected. If the number of common feeders is the same, the line tact becomes high. A new program is added to the cluster.

  The determination unit 35 determines whether or not the feeder 4 used in the new production program can be assigned to the feeder bank 24 in which the feeder arrangement of the existing cluster searched by the search unit 34 is set. When the determining unit 35 determines that the feeder 4 of the new production program can be assigned, the new production program is added to the existing cluster. When the determination unit 35 determines that the feeder 4 of the new production program cannot be assigned, a new cluster for the new production program is generated in the reservation file F, and the new production program is added to the new cluster. You.

  When a new cluster is generated, the feeder arrangement of the existing cluster and the new cluster may be reassigned so as to minimize the change of the feeder arrangement of the existing cluster. In this case, the allocating unit 33 partially changes the feeder arrangement of the existing clusters to create an empty space in the feeder bank 24, and allocates a new production program feeder 4 to the empty space in the feeder bank 24. The change of the feeder arrangement of the existing cluster is suppressed to a minimum so as not to cause a large replacement work in consideration of the work load of the operator.

  The notification unit 36 notifies the mounting device 2 of the production program and the allocation information of the feeder 4. Note that the registration unit 31, the integration unit 32, the allocation unit 33, the search unit 34, the determination unit 35, the notification unit 36, and the storage unit 37 of the host computer 3 are configured by a processor, a memory, and the like that execute various processes of each unit. I have. The memory is constituted by one or a plurality of storage media such as a ROM (Read Only Memory) and a RAM (Random Access Memory) depending on the application. In the memory, in addition to the production program registered in the reservation file F, a program for causing the host computer 3 to execute an allocation process described later is stored.

  With reference to FIGS. 4 to 7, a method of allocating feeders to feeder banks will be described. FIG. 4 is a diagram showing an example of a feeder allocation state according to the present embodiment. 5 to 7 are diagrams illustrating an example of a feeder assignment method according to the present embodiment. It is assumed that each cluster of the reservation file shown in FIGS. 4 to 7 has been optimized.

  As shown in FIG. 4, a plurality of production programs are registered in the reservation file F for each cluster. In cluster 1, five production programs ae are registered, and in cluster 2, three production programs fh are registered. In the feeder bank 24 at this time, in the cluster 1, feeders 4B, 4C, 4D, 4E, and 4A are set in order from the left with both ends of the feeder bank 24 being spaced by one slot. In the cluster 2, feeders 4F, 4C, 4D, and 4G are set in order from the left with a left end of the feeder bank 24 in the drawing left one slot. A new production program x, y is scheduled to be added to the reservation file F.

  As shown in FIG. 5, when adding a new production program x to the reservation file F, clusters 1 and 2 including any of the feeders 4B, 4D, and 4F used in the new production program x are searched. . Then, it is determined whether all of the feeders 4B, 4D, and 4F can be assigned to the clusters 1 and 2. In cluster 1, feeders 4B and 4D are used, and empty slots for feeders 4F remain in feeder bank 24. Also in the cluster 2, the feeders 4F and 4D are used, and an empty slot for the feeder 4B remains in the feeder bank 24.

  Therefore, it is possible to add a new production program x to each of the clusters 1 and 2. In this case, a new production program x is added to the cluster 1 having the highest line tact. Note that the line tact is obtained by a simulation of the mounting process in the mounting apparatus 2 or the like. Thus, the feeders 4B, 4D, and 4F used in the new production program x can be assigned to the feeder bank 24 without changing the feeder arrangement of the existing cluster. Therefore, it is only necessary to attach the feeder 4F to the feeder bank 24, and the work load of the operator can be reduced.

  As shown in FIG. 6, when a new production program y is added to the reservation file F, a cluster 1 including any of the feeders 4E, 4H, and 4I used in the new production program y is searched. Then, it is determined whether all of the feeders 4E, 4H, and 4I can be assigned to the cluster 1. In the cluster 1, the feeder 4E is used, but there are not enough empty slots for the feeders 4H and 4I. Therefore, a new cluster is generated after the clusters 1 and 2 in the reservation file F, and a new production program y is added to the new cluster.

  Thus, the feeders 4E, 4H, and 4I used in the new production program y can be assigned to the feeder bank 24 without changing the assignment of the feeders 4 of the existing clusters 1 and 2. The production program y of the new cluster is executed after the production program of the existing clusters 1 and 2 ends. At this time, if there is a spare exchange cart, the spare exchange cart may be used for a new cluster. By attaching the feeders 4E, 4H, and 4I in advance to the feeder bank 24 of the spare exchange cart, the entire feeder bank 24 can be exchanged simply by replacing the exchange cart used in the existing cluster 2 with the spare exchange cart. . Therefore, it is only necessary to replace the exchange trolley, and the work load on the operator can be reduced.

  As shown in FIG. 7, when new production programs x and y are added to the reservation file F, the feeder arrangement of the existing clusters 1 and 2 is partially changed, and the new production programs are added to the existing clusters 1 and 2. x and y may be added. In this case, as described above, the new production program x is added to the existing cluster 1, and the feeder 4F is assigned to the leftmost slot in the feeder bank 24 in the figure. Next, the cluster 2 and the new cluster feeder 4 are allocated so that the feeder arrangement of the cluster 1 is not changed. At this time, the feeder arrangement of the subsequent cluster is determined so as to succeed the feeder arrangement of the previous cluster as much as possible.

  In this case, a plurality of allocation patterns are generated for the cluster 2 and the new cluster based on the feeder arrangement of the cluster 1. Among the plurality of allocation patterns, the allocation pattern that minimizes the number of exchanges of the feeder 4 is set in the cluster 2 and the new cluster. Thus, the feeders 4E, 4H, and 4I used in the new production program y can be allocated to the feeder bank 24 by slightly changing the existing feeder arrangement. Therefore, the work of replacing the feeder 4 with the feeder bank 24 can be minimized, and the work load of the operator can be reduced.

  With reference to FIG. 8, a method of allocating feeders when a new production program is added to the reservation file will be described. FIG. 8 is an example of a flowchart of the feeder assignment method according to the present embodiment. Note that the following method of adding a new production program is an example, and a part of the process can be appropriately changed or omitted.

  As shown in FIG. 8, when a new program is registered in the reservation file, an existing cluster using the same feeder 4 (see FIG. 1) as the new production program is searched (step S01). Next, it is determined whether all the feeders 4 used in the new program can be allocated to the feeder bank 24 (see FIG. 1) in which the feeder arrangement of the existing cluster is set (step S02). In this case, it is determined whether the assignment is possible based on the vacancy of the feeder bank 24 in the existing cluster and the feeder 4 used in each production program of the existing cluster.

  If the feeder 4 of the new production program can be assigned to an existing cluster (Yes in step S02), it is determined whether there are a plurality of existing clusters that can be assigned (step S03). If there are a plurality of existing clusters that can be assigned (Yes in step S03), a new production program is added to a cluster having a higher line tact among the plurality of existing clusters (step S04). Then, the feeder 4 used in the new production program is allocated to the feeder bank 24 of the existing cluster without changing the feeder arrangement of the existing cluster (step S05).

  If there is only one existing cluster that can be assigned (No in step S03), a new production program is added to the existing cluster (step S06). Then, the feeders 4 used in the new production program are allocated to the feeder banks 24 of the existing cluster without changing the feeder arrangement of the existing cluster (step S07). On the other hand, in step S02, when the feeder 4 of the new production program cannot be assigned to the existing cluster (No in step S02), a new cluster is generated for the new production program (step S08).

  When a new cluster is generated, a new production program is added to the new cluster (Step S09). Then, the feeders 4 used in the new production program are allocated to the feeder banks 24 of the new cluster without changing the feeder arrangement of the existing cluster (step S10). Next, it is determined whether or not the feeder arrangement of the cluster in the reservation file F (see FIG. 2) is to be optimized again (step S11). If the feeder arrangement is not optimized again (No in step S11), the processing is terminated. When re-optimizing the feeder arrangement (Yes in step S11), the feeder arrangement of the existing cluster and the new cluster is re-assigned so as to minimize the change in the feeder arrangement of the existing cluster (step S12).

  As described above, in the host computer 3 according to the present embodiment, even if a new production program is added to an existing cluster in the reservation file F, the feeder arrangement of the existing cluster has priority. Therefore, the feeders 4 used in the new production program can be assigned to the feeder bank 24 without significantly changing the current feeder arrangement with respect to the feeder bank 24. The work of replacing the feeder 4 can be minimized, and the work load on the operator can be reduced. Thus, the feeder 4 can be assigned to the feeder bank 24 in consideration of the operator's work load.

  The present invention is not limited to the above embodiment, and can be implemented with various modifications. In the above embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited thereto, and can be appropriately changed without departing from the effects of the present invention. In addition, the present invention can be appropriately modified and implemented without departing from the scope of the object of the present invention.

  For example, in the present embodiment, the search unit 34 may be configured to search for a cluster that uses at least one feeder 4 that is the same as the new production program. For example, a cluster that uses three or more feeders 4 that are the same as the new production program may be searched, or a cluster that uses only one feeder 4 that is the same as the new production program may be searched.

  In the present embodiment, the determination unit 35 determines whether or not the feeder 4 used in the new production program can be assigned based on the availability of the feeder bank 24 in the existing cluster. The configuration is not limited. The determination unit 35 may determine whether or not the feeder 4 can be assigned in consideration of other conditions such as the specifications of the feeder 4 irrespective of the availability of the feeder bank 24.

  Further, in the present embodiment, when re-optimizing the feeder arrangement between the existing cluster and the new cluster, a configuration in which a plurality of allocation patterns are generated has been described. However, the present invention is not limited to this configuration. For example, a learning unit may be provided in the host computer 3 so that the learning unit learns the assignment of the feeders 4 to optimize the optimal feeder arrangement.

  Further, in the present embodiment, the host computer 3 is configured to include the search unit 34 for searching for a cluster and the determination unit 35 for determining whether or not the feeder 4 can be allocated. However, the present invention is not limited to this configuration. The host computer 3 may not include the search unit 34 and the determination unit 35.

  Further, in the present embodiment, the substrate W is not limited to a printed substrate, and may be a flexible substrate mounted on a jig substrate.

  As described above, the present invention has the effect of optimizing the allocation of feeders by adding a new production program without increasing the work load of the operator. The present invention is useful for an assignment device that assigns a feeder, a production system, an assignment method, and a program used in the assignment device.
