The carrier tape is provided with a plurality of component storage portions for storing the components 120 along the supply direction of the tape 122 at substantially equal intervals. The tape 122 holds a predetermined number of parts 120 and is wound around a reel 123.

  The reel 123 is configured to be mounted on the component mounting apparatus 100 while being held by the tape feeder 121. Further, the reel 123 is stored in a storage place such as a shelf when it is not used by the component mounting apparatus 100. The reel 123 manages the number of reels in stock for each type of component 120 to be held, including the number of reels used for component mounting and the number of stored reels.

  The head unit 20 has a function of sucking and mounting the component 120 supplied from the tape feeder 121 via the suction nozzle 21 on the substrate 110. Further, as shown in FIG. 2, the head unit 20 is configured to be movable in the X direction along a head unit support portion 30 extending in the X direction. The head unit support portion 30 is configured to be movable in the Y direction along a pair of fixed rail portions 40 provided on the base 10 and extending in the Y direction. Thereby, the head unit 20 is configured to be able to move on the base 10 in the XY plane. The head unit 20 is provided with six suction nozzles 21 arranged in a row in the X direction so as to protrude downward. The suction nozzle 21 is configured to be able to suck and hold the component 120 supplied from the tape feeder 121 at the tip.

  The component mounting apparatus 100 includes a mounting control processing unit 50. The mounting control processing unit 50 is configured to control component mounting work based on an instruction from the control device 200 (see FIG. 1). Specifically, the mounting control processing unit 50 includes a CPU that executes logical operations, a ROM (Read Only Memory) that stores programs for controlling the CPU, and a RAM that temporarily stores various data during operation of the apparatus. (Random Access Memory). Further, the mounting control processing unit 50 is configured to control servo motors (not shown) that individually drive the substrate transport conveyor 11 and the head unit 20 in accordance with a program stored in the ROM.

  Here, in the first embodiment, the control apparatus 200 is connected to two component mounting apparatuses 100 as shown in FIG. The control device 200 is configured by a PC (personal computer). Further, the control device 200 is configured to control the mounting operation of the component 120 on the substrate 110 by the two component mounting devices 100 respectively provided on the two substrate manufacturing lines. Specifically, the control device 200 is configured to determine the order of board production (mounting of the component 120 on the board 110) by the component mounting apparatus 100. That is, the control device 200 is configured to determine the order of manufacturing for each type of substrate.

  Specifically, the control device 200 is configured so as to preferentially consider the low inventory quantity of the reels 123 and to determine the order of board production using the components 120 of the reels 123 with a relatively small inventory quantity. ing. That is, the control device 200 is configured so as to preferentially consider the small inventory quantity of the reels 123 and to determine the order of board production using the components 120 of the reels 123 with the smallest inventory quantity.

  In addition, when manufacturing different types of boards by the component mounting apparatus 100, the control device 200 preferentially considers the small number of inventory of the reels 123, and the components 120 of the reels 123 that have a relatively small number of inventory. The order of manufacturing two or more types of substrates each using the above is determined so that the setup for mounting the reel 123 to the component mounting apparatus 100 can be made common. In addition, as a setup in the case of manufacturing a board | substrate with the component mounting apparatus 100, the operation | work which mounts the reel 123 holding the component 120 required for manufacture of a board | substrate to the component mounting apparatus 100 is performed. Further, in the case where the setup for manufacturing two or more types of substrates is made common, the reels 123 holding the necessary types of components 120 for each type of substrate to be manufactured are first mounted on the component mounting apparatus 100. Work to be done.

  For example, as shown in FIG. 5, when three types of substrates of type A, type B, and type C are manufactured, the types of components 120 necessary for manufacturing the substrate of type A are component a, component b, and component c, part e, and part i, and the types of parts 120 necessary for manufacturing the substrate of type B are part b, part c, part d, part g, and part h. Further, the types of the parts 120 necessary for manufacturing the substrate of the type C are the parts b, d, e, f and j. Then, when the substrate of the product type A and the substrate of the product type C are manufactured by common setup as in the example shown in FIG. 7, before the manufacture of the substrate of the product type A and the product type C, the substrate of the product type A and the product type C is manufactured. A reel 123 holding a component 120 of all necessary types (component a, component b, component c, component d, component e, component f, component j and component i) is mounted on the component mounting apparatus 100. Further, after the manufacture of the substrate of the product type A and the product C and before the manufacture of the substrate of the product type B, the types (parts b, c, c, d, g and h) required for the manufacture of the product B The reel 123 holding the component 120 is mounted on the component mounting apparatus 100 while being replaced. In this way, by sharing the setup, it is possible to reduce the number of setups. Thereby, it is possible to reduce the work by an operator. It is also possible to reduce the total substrate manufacturing time.

  Next, a setup group creation process performed by the control device 200 will be described with reference to FIGS.

  First, in step S1 shown in FIG. 3, the control device 200 reads target substrate data. Specifically, based on the mounting program, the control device 200 determines the types of required parts 120 of the target board (type A, type B, and type C), the number of required parts 120, and the number of boards to be manufactured. Read data about. In step S2, the control device 200 acquires target component information. Specifically, the control device 200, based on the mounting program, for each type of target component (required component 120) as shown in FIG. Information about the number and the number of parts 120 used for manufacturing is acquired. For example, in the case of the part a, the number of reels in stock is 2, the number of types of boards used for manufacturing is 1, and the number of parts 120 used for manufacturing is 600.

  In step S3, the control device 200 performs priority component weighting processing. Specifically, as shown in FIG. 4, the control device 200 determines the number of target part inventory reels in step S <b> 3 a. In addition, the control device 200 gives priority to a component 120 having a small number of stock reels. For example, in the example shown in FIG. 6, the part 120 having the smallest number of inventory reels and one type (part e, part g, and part j) is given priority. Next, priority is given to the part 120 of the type (part a, part f, part h, and part i) whose inventory reel number is two. Next, the part 120 of the type (part c and part d) whose inventory reel number is 3 is given priority. Finally, priority is given to the part 120 of the type (part b) whose inventory reel number is four.

  In step S3b, the control device 200 determines the number of types of boards on which the target component is used for manufacturing. In addition, the control device 200 gives priority to the type of component 120 that has a large number of types of substrates that are used for manufacturing the target component. For example, in the example shown in FIG. 6, among the same priority order types (part e, part g, and part j), the two types (parts e) of parts 120 having the largest number of types of boards used for manufacturing are selected. Prioritize. Therefore, the priority order of the component 120 of the type of the component e is first. Next, priority is given to the component 120 of the type (component g and component j) of which the number of types of substrates used for manufacturing is one. Similarly, the control device 200 determines the priority of the part 120 of the same priority order based on the number of inventory reels.

  In step S3c, the control device 200 determines the number of points used for manufacturing the target component. In addition, the control device 200 gives priority to the type of component 120 having a large number of points used for manufacturing the target component. For example, in the case of the example shown in FIG. 6, among the types (parts g and j) in the same priority order, the part 120 of the type (part g) having the highest number of points used for manufacturing the target part is given priority. Therefore, the priority order of the part 120 of the part g type is second, and the priority order of the part 120 of the part j type is third. Similarly, the control device 200 determines the priority of the parts 120 of the same priority order based on the number of stock reels and the number of board types.

  In step S3d, the control device 200 records the priority for each type of target component in a memory (not shown).

  In step S4 of FIG. 3, the control device 200 arranges for each type of component 120 based on the priority order of the type of component stored in the memory. Specifically, the control device 200 performs a common board manufacturing setup, and distributes and arranges the components 120 for each group of the common setup. In other words, the control device 200 arranges the components 120 so that the board manufacturing process using the components 120 of a high priority type is shared. For example, in the case of the example shown in FIG. 6, the control device 200 is configured as shown in FIG. 7 so as to share the production setup of the boards (type A and type C) using the component e having the highest priority. The parts 120 are arranged. In addition, the control device 200 arranges the components 120 so that the production of the substrate of the product type B is performed independently.

  Thereafter, as shown in FIG. 3, the control device 200 determines whether or not the number of parts arranged is larger than the number of inventory reels in step S <b> 5. The number of parts arranged is the total number of parts 120 arranged in each setup group. For example, in the example shown in FIG. 7, the part a is used only in the types A and C, and the number arranged is one. The part b is used for both the types A and C and the type B, and the number of parts b is two.

  When the number of component arrangements is greater than the number of inventory reels, the control device 200 outputs an error, returns to step S1, changes the conditions, and repeats steps S1 to S5 until the number of component arrangements is equal to or less than the number of inventory reels. . On the other hand, when the number of parts arranged is equal to or less than the number of inventory reels, the control device 200 ends the setup group creation process.

  In the first embodiment, as described above, a board (mounting board) using the component 120 of the reel 123 with a relatively small inventory quantity (stock reel quantity) in consideration of the low inventory quantity of the reel 123 as a priority. ) Can be preferentially determined in order to manufacture the boards using the components 120 of the reels 123 with a relatively small number of stocks. When manufacturing substrates, reels 123 with a relatively small number of inventory can be allocated to manufacture of each substrate and used efficiently. Thereby, the inventory number of the reels 123 can be minimized.

  In the first embodiment, as described above, the control device 200 preferentially considers the small inventory quantity of the reels 123, and manufactures a board using the component 120 of the reels 123 with the smallest inventory quantity. Configure to determine the order. As a result, the order of manufacturing the boards using the parts 120 of the reels 123 with the smallest inventory number can be determined with priority, so the reels 123 with the smallest inventory quantity can be obtained while minimizing the inventory quantity of the reels 123. The production of the substrate using the component 120 can be performed with the highest priority.

  Further, in the first embodiment, as described above, when the control device 200 manufactures different types of boards using the component mounting device 100, the inventory of the reels 123 is preferentially taken into consideration and the inventory is reduced. The order of manufacturing two or more types of boards using the components 120 of the reel 123 with a relatively small number is determined in an order in which the setup for mounting the reel 123 on the component mounting apparatus 100 can be made common. . As a result, the reels 123 with a relatively small number of stocks can be used in common for the production of two or more types of substrates. Therefore, a plurality of types of substrates can be formed using the parts 120 of the reels 123 with the minimum necessary number of stocks. It can be manufactured easily.

  In the first embodiment, as described above, when there are a plurality of reels 123 having the same small number of inventory, the control device 200 is preferentially considered in terms of the number of types of boards used. The manufacturing order of the boards using the component 120 having a relatively small number of stocks and a relatively large number of types of boards to be used is determined. As a result, it is possible to preferentially share the board manufacturing setup using the parts 120 having a relatively large number of types of boards to be used. Therefore, it is easy to use the parts 120 of the reel 123 having the minimum necessary number of stocks. A substrate can be manufactured.

(Second Embodiment)
Next, a component mounting system 1 according to a second embodiment of the present invention will be described with reference to FIGS. 5, 6 and 8 to 11. In the second embodiment, unlike the first embodiment, a configuration in which the order of substrate manufacturing is adjusted between two substrate manufacturing lines and determined will be described.

  Here, in the second embodiment, the control device 200 preferentially considers the small inventory number of the reels 123 so that the time for using the components 120 of the reels 123 with relatively small inventory numbers does not overlap. The two component mounting apparatuses 100 (two substrate manufacturing lines) are configured to determine the order of manufacturing the substrate (mounting substrate). Specifically, the control device 200 makes a board manufacturing plan for each component mounting apparatus 100 (board manufacturing line), and then manufactures a board between the component mounting apparatuses 100 (between each board manufacturing line). The order is determined and adjusted.

  In addition, the control device 200 preferentially considers the small inventory quantity of the reels 123, so that the order of manufacturing the boards using the relatively large number of components 120 of the reels 123 with a relatively small inventory quantity becomes faster. It is configured to be determined. For example, in the case of the example shown in FIGS. 5 and 6, in the manufacture of the type A substrate, one type (part e) of the parts whose inventory number of the reels 123 is 1 is used. In the manufacture of the type B substrate, one type (part g) of the parts whose inventory number of reels 123 is 1 is used. Further, in the production of the substrate of the type C, two types (part e and part j) of the parts whose inventory number of the reel 123 is 1 are used. In this case, the control device 200 determines the order of manufacturing the substrate of the product type C that uses a relatively large number (two types) of the components 120 of the reels 123 with a relatively small number of stocks (two types).

  Next, with reference to FIG. 8, the manufacturing plan planning process performed by the control device 200 will be described.

  In step S <b> 11, the control device 200 acquires the number of inventory reels of the component 120. Specifically, the control device 200 acquires the inventory number of the reels 123 managed based on the mounting program. In step S <b> 12, the control device 200 determines the number of types of the parts 120 having the inventory reel number of 1. Specifically, the control device 200 determines, for each type of board to be manufactured, the manufacture of a board of a type in which many types of parts 120 with the number of inventory of the reel 123 being used are used.

  In step S13, the control device 200 plans the manufacture of the substrate. Specifically, the control device 200 makes a board production plan for each board production line (first line and second line). In addition, the control device 200 plans so that the order of manufacturing the types of boards in which the types of parts 120 having the inventory number of the reels 123 of 1 are used is advanced. For example, in the case of the example shown in FIG. 10, in the first line, the production of the board of the product type AAA, in which the parts 120 with the number of stocks of the reels 123 of 1 are most frequently used, is planned in the first order. . In the second line, the production of the substrate of the product type VVV in which the component 120 having the inventory number of one reel 123 is most frequently used is planned to be in the first order.

  In step S14, the control device 200 estimates manufacturing start / end times based on the manufacturing plan. For example, as in the example shown in FIG. 10, in the first line, the production start / end times of each of the product type AAA, the product type BBB, the product type CCC, and the product type DDD are estimated. For example, in the case of the product type AAA, the manufacturing start time is 9:00 including the setup time, and the manufacturing end time is 9:50. Further, in the second line, the production start / end times of the product type VVV, the product type XXX, the product type YYY, and the product type ZZZ are estimated. For example, in the case of the product type VVV, the manufacturing start time is 9:00 including the setup time, and the manufacturing end time is 10:20.

  In step S15 of FIG. 8, the control device 200 determines whether or not the planning of all the board production lines has been completed. If the plan is not completed, the process returns to step S13, and a board production plan for the board production line for which the plan is not completed is made. On the other hand, if the plan is completed, the control device 200 ends the production plan planning process.

  Next, a manufacturing plan adjustment process performed by the control device 200 will be described with reference to FIG.

  When the manufacturing plan planning process ends, in step S21, the control device 200 selects a manufacturing plan to be compared. Specifically, the control device 200 selects a manufacturing plan for a substrate manufacturing line having manufacturing plans that are performed in the same time zone. Here, the control device 200 selects the production plan in the first line and the production plan in the second line. In step S <b> 22, the control device 200 determines whether there is a part 120 that is used repeatedly at the same time. If there is no redundantly used part 120, the control device 200 ends the manufacturing plan adjustment process.

  If there is a part 120 that is used redundantly, in step S23, the control device 200 determines, for each type of part 120, whether or not the total number of reels 123 that are used is larger than the number of reels 123 in stock. That is, when there are parts 120 that are used redundantly at the same time, it is determined whether the reels 123 of the parts 120 to be used are sufficient. If the total number of reels 123 used is equal to or less than the number of inventory reels, the control device 200 ends the manufacturing plan adjustment process.

  If the total number of reels 123 used is larger than the number of inventory reels, in step S24, the control device 200 acquires the usage time zone of the parts 120 that are used redundantly. For example, in the case of the example shown in FIG. 10, the parts 120 with the number of stock reels of 1 are redundantly used for the product type BBB and the product type VVV. In this case, the control device 200 acquires a time zone from 9:50 to 10:20 as a usage time zone of the component 120 that is used redundantly. In step S25, the control device 200 estimates the manufacturing time. In the case of the example shown in FIG. 10, the control device 200 estimates that the manufacturing time of the product type BBB is 30 minutes from 9:50 to 10:20, and the manufacturing time of the product type VVV is from 9:00 to 10 Estimated to be 80 minutes up to 20 minutes.

  In step S26, the control device 200 replaces the manufacturing plan. Specifically, the control device 200 changes the order in which the boards are manufactured so that the time for using the component 120 of the reel 123 with the inventory number 1 does not overlap. For example, in the example illustrated in FIG. 10, the control device 200 switches the order of the production of the substrate of the type AAA on the first line and the production of the substrate of the product BBB. Further, the control device 200 switches the order of the manufacture of the substrate of the second line type XXX and the manufacture of the substrate of the type VVV. Thus, as shown in FIG. 11, the time for manufacturing the first line type BBB and the time for manufacturing the second line type VVV are adjusted so as not to overlap. Thereafter, the control device 200 ends the manufacturing plan adjustment process.

  In addition, the other structure of 2nd Embodiment is the same as that of the said 1st Embodiment.

  As described above, also in the configuration of the second embodiment, as in the first embodiment, the parts of the reel 123 with a relatively small inventory quantity are preferentially considered in consideration of the small inventory quantity of the reel 123. By providing the control device 200 that determines the order of manufacturing substrates (mounting substrates) using 120, the number of inventory of the reels 123 can be minimized.

  In the second embodiment, as described above, the control device 200 preferentially considers the small inventory quantity of the reels 123 and takes time to use the components 120 of the reels 123 with a relatively small inventory quantity. The order of board production by the plurality of component mounting apparatuses 100 is determined so as not to overlap. As a result, the reels 123 having a relatively small number of inventory can be prevented from being simultaneously used by the plurality of component mounting apparatuses 100, so that a plurality of types can be obtained by using the components 120 of the reel 123 having the minimum necessary number of inventory. The substrate can be efficiently manufactured.

  In the second embodiment, as described above, the control device 200 preferentially considers the small inventory quantity of the reels 123 and relatively moves the parts 120 of the reels 123 with relatively small inventory quantities. The structure is such that the order of manufacturing the frequently used substrates is determined earlier. This makes it possible to complete the production of substrates using a relatively large number of reels 123 with a relatively small number of inventory at a time, so that the reels 123 with a relatively small number of inventory can be easily combined with a plurality of component mounting apparatuses 100 at the same time. It can be prevented from being used.

  The remaining effects of the second embodiment are similar to those of the aforementioned first embodiment.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiments but by the scope of claims for patent, and further includes all modifications within the meaning and scope equivalent to the scope of claims for patent.

  For example, in the first and second embodiments, the example of the configuration in which the reel around which the tape holding the component is wound is used as the component holding portion of the present invention, but the present invention is not limited to this. In the present invention, a tray or the like holding a component may be used as the component holding unit.

  In the first and second embodiments, the component mounting system has two board manufacturing lines, and one example of a configuration in which one component mounting apparatus is provided in one board manufacturing line is shown. It is not limited to this. In the present invention, the component mounting system may have one or three or more board production lines. Moreover, the structure which provides a some component mounting apparatus in one board | substrate production line may be sufficient.

  Moreover, although the control apparatus 200 (control part) showed the example which shares the setup of manufacture of two types of board | substrates in the said 1st Embodiment, this invention is not limited to this. In the present invention, the control unit may share a setup for manufacturing three or more types of substrates.

  Further, in the second embodiment, the example of the configuration in which the substrate production plan is made without sharing the setup is shown, but the present invention is not limited to this. In the present invention, a substrate production plan may be made by making the setup common for each substrate production line. Further, the setup may be shared while adjusting the order of manufacturing the substrates between the substrate manufacturing lines.

  In the first and second embodiments, for the sake of convenience of explanation, the processing of the control device (control unit) of the present invention has been described using a flow-driven flowchart that performs processing in order along the processing flow. The present invention is not limited to this. In the present invention, the processing operation of the control unit may be performed by event-driven (event-driven) processing that executes processing in units of events. In this case, it may be performed by a complete event drive type or a combination of event drive and flow drive.
