A plurality of types of components are mounted on each substrate PP. Furthermore, the types of components to be mounted are different for each type of substrate PP. Therefore, in the mounting machine 2, in order to produce component-mounted boards corresponding to a plurality of types of boards PP, the number of feeders 24F corresponding to the types of components used for the production is required. The plurality of feeders 24F may be arranged directly in the component supply section 24, or may be arranged in the component supply section 24 using a component supply unit 24U as shown in FIG.

Setup work is performed by an operator or a work robot. The setup work is roughly divided into an internal setup work performed on the mounting machine 2 and an external setup work performed outside the mounting machine 2 . When the internal setup work is being performed for the mounting machine 2, the production of component-mounted boards by the mounting machine 2 is temporarily put on standby until the internal setup work is completed. On the other hand, since the external setup work is performed outside the mounting machine 2, it is possible to continue production of component-mounted boards by the mounting machine 2 even during the external setup work.

For multiple types of boards PP, the higher the degree of commonality of the types of parts to be mounted, the more advantageous the production efficiency when the same feeder arrangement is used. Grouping is preferred. For example, substrates PP having a high degree of commonality in the types of components to be mounted exceeding a predetermined value may be included in the same pre-registration group.

The pre-registration group information RGI is information in which group type information RG1, registered board type information RG2, mounting program RG3, and evaluation element information RG4 are associated with each other.

Also, "board R" indicated by registered board type information RG2 belongs to "group G5" indicated by group type information RG1. Thus, there may be situations where the same type of substrate belongs to different groups. However, in such a case, the implementation program RG3 and the evaluation element information RG4 associated with the group type information RG1 are different.

The mounting program RG3 indicates a mounting program used in the mounter 2 to mount a component on the board indicated by the registered board type information RG2, and is registered board type information belonging to the pre-registered group indicated by the group type information RG1. It is set for each substrate indicated by RG2. Even if the board indicated by the registered board type information RG2 is the same, if the group type indicated by the group type information RG1 is different, the contents of the program indicated by the mounting program RG3 are different. Referring to FIG. 5, the mounting program for "Board A", "Board B", "Board C", and "Board D" indicated by the registered board type information RG2, " "PGA1", "PGB1", "PGC1" and "PGD1" indicated by implementation program RG3 associated with group G1" and "PGA2", "PGB2" and "PGC2" associated with "group G2" , and “PGD2” differ in program content. Similarly, regarding the mounting programs for "board O" and "board R" indicated by registered board type information RG2, "PGO3" and "PGO3" indicated by mounting program RG3 associated with "group G3" indicated by group type information RG1. "PGR3" differs in program content from "PGO4" associated with "group G4" and "PGR5" associated with "group G5".

Information related to the control includes, for example, the mounting position of each component on the board, the arrangement position within the component supply unit 24 of the feeder 24F that supplies each component to be mounted on the board, and the information used when mounting the component on the board. The information includes the arrangement of the mounting heads 251 in the head unit 25, the order of mounting the components by the mounting heads 251, and the like.

In the mounting machine 2, the component mounting operation by the head unit 25 having the plurality of mounting heads 251 is executed according to the mounting program indicated by the mounting program RG3. Regarding the component mounting operation on the "board A" indicated by the registered board type information RG2 belonging to the "group G1" indicated by the group type information RG1, the operation according to "PGA1" indicated by the mounting program RG3 is taken as an example. The explanation is as follows. When the “board A” is conveyed by the conveyor 23 , each mounting head 251 in the head unit 25 picks up components from the plurality of feeders 24</b>F arranged in the component supply section 24 simultaneously or continuously. After that, the operation of moving the head unit 25 onto the “board A” and sequentially mounting the components continues until all the components are mounted on the “board A”, in the component mounting order indicated by the mounting program “PGA1”. is repeated according to

Referring to FIG. 5, the cycle times for "Board A", "Board B", "Board C", and "Board D" indicated by the registered board type information RG2 are calculated according to the group type information RG1. While the cycle times indicated by the cycle time information RG41 associated with the "group G1" are "30", "40", "50" and "60", the cycle time information RG41 associated with the "group G2" The cycle times indicated by are "60", "50", "40" and "30". In this case, in "group G1", the cycle times of "substrate A", "substrate B", "substrate C" and "substrate D" are set to increase in this order. , the production efficiency increases in the opposite order of the cycle time. That is, it can be said that "group G1" is a pre-registered group in which production efficiency of "substrate A" is emphasized the most. On the other hand, in "group G2", the cycle times of "substrate A", "substrate B", "substrate C" and "substrate D" are set to decrease in this order. , the production efficiency increases in the same order as the cycle time. That is, it can be said that "group G2" is a pre-registered group in which production efficiency of "substrate D" is given the highest priority.

Similarly, regarding the cycle times for "board O" and "board R" indicated by registered board type information RG2, the cycle time indicated by cycle time information RG41 associated with "group G3" indicated by group type information RG1 is In contrast to "30" and "60", the cycle time indicated by the cycle time information RG41 associated with "group G4" is "20" and the cycle time information RG41 associated with "group G5" is The indicated cycle time is "30".

Similarly, FIG. 8B shows the production planning procedure corresponding to the production request information PRI of FIG. 7B, and FIG. 8C shows the production planning procedure corresponding to the production request information PRI of FIG. 7C.

First, referring to FIG. 8A, a procedure for creating a production plan corresponding to the production request information PRI of FIG. 7A will be described. When the production request acquisition unit 452 acquires the production request information PRI of FIG. 7A, the production plan creation unit 453 reads the pre-registered group information RGI of FIG. Then, the production plan creation unit 453 creates a group that includes all of "board A", "board B", "board D", "board O" and "board R" indicated by the production request board type information PR1. A combination pattern of the pre-registered groups indicated by the seed information RG1 is created based on the registered board seed information RG2.

The evaluation value is calculated for each of CP1 to CP4. Then, the production planning unit 453 selects the combination pattern with the smallest calculated evaluation value as the attention combination pattern ACP.

For example, assume that the evaluation value is the total production time TPT. In the production request information PRI of FIG. 7A, among the "board A", "board B" and "board D" indicated by the production request board type information PR1, the production quantity of "board A" is the smallest at "10". , and the number of production of "substrate D" is extremely large at "100". Therefore, when comparing "group G1" and "group G2" as pre-registered groups to which "board A", "board B", and "board D" belong, the cycle time indicated by the cycle time information RG41 is the number of production units. "Group G2", which is the smallest for "board D" with a large number of "board D" and places the highest priority on the production efficiency of this "board D", is selected as a pre-registered group that constitutes the attention combination pattern ACP. On the other hand, in the production request information PRI of FIG. 7A, the production numbers of "board O" and "board R" indicated by the production request board type information PR1 are both "20", which is not so large. Therefore, when comparing the "group G3" as the pre-registered group to which the "substrate O" and the "substrate R" belong to and the combination of the "group G4" and the "group G5", the "substrate O" and the "substrate R" are grouped together, the "group G3" in which the number of setups SN is small and the setup work time ST is small is selected as a pre-registered group constituting the combination pattern ACP of interest. Therefore, the production plan creation unit 453 selects the third combination pattern CP3, which is a combination of "group G2" and "group G3", as the attention combination pattern ACP, corresponding to the production request information PRI of FIG. 7A.

When the selection of the attention combination pattern ACP of FIG. 8A is completed in response to the production request information PRI of FIG. 7A, the production plan creating unit 453 creates the production plan information PPI of FIG. 9 indicating the production plan.

When the production request acquisition unit 452 acquires the production request information PRI of FIG. 7B, the production plan creation unit 453 reads the pre-registered group information RGI of FIG. Then, the production plan creation unit 453 creates a group that includes all of "board A", "board B", "board D", "board O" and "board R" indicated by the production request board type information PR1. A combination pattern of the pre-registered groups indicated by the seed information RG1 is created based on the registered board seed information RG2.

A fourth combination pattern CP4 made up of a combination with "group G5" is created.

When the creation of the first to fourth combination patterns CP1 to CP4 is completed, the production plan creation unit 453 creates combination patterns based on the evaluation element information RG4 of the pre-registered group information RGI and the production quantity information PR2 of the production request information PRI. The evaluation value is calculated for each of CP1 to CP4. Then, the production planning unit 453 selects the combination pattern with the smallest calculated evaluation value as the attention combination pattern ACP.

For example, assume that the evaluation value is the total production time TPT. In the production request information PRI of FIG. 7B, among the "board A", the "board B" and the "board D" indicated by the production request board type information PR1, the production quantity of the "board D" is the smallest at "10". , and the number of production of "substrate A" is "100", which is extremely large. Therefore, when comparing "group G1" and "group G2" as pre-registered groups to which "board A", "board B", and "board D" belong, the cycle time indicated by the cycle time information RG41 is the number of production units. The "group G1" in which the production efficiency of the "substrate A" is most emphasized is selected as the pre-registered group that constitutes the combination pattern ACP of interest. On the other hand, in the production request information PRI of FIG. 7B, the production numbers of "board O" and "board R" indicated by the production request board type information PR1 are both "200", which is extremely large. For this reason, when comparing "group G3" as a pre-registered group to which "substrate O" and "substrate R" belong, and the combination of "group G4" and "group G5", cycle time information is more than setup work time ST. Priority is given to the cycle time indicated by RG41. That is, the combination of "group G4" and "group G5" whose cycle time is short for "substrate O" and "substrate R" with large production numbers is selected as a pre-registered group constituting the attention combination pattern ACP. Accordingly, the production plan creation unit 453 creates the second combination pattern CP2, which is a combination of "group G1", "group G4", and "group G5", in correspondence with the production request information PRI of FIG. 7B. Selected as ACP.

When the selection of the attention combination pattern ACP of FIG. 8B is completed in response to the production request information PRI of FIG. 7B, the production plan creating unit 453 creates the production plan information PPI of FIG. 10 indicating the production plan. In the production planning information PPI of FIG. 10, the order of production of "board A", "board B" and "board D" belonging to "group G1" constituting the attention combination pattern ACP of FIG. 8B is "1", "2". and "3", the production order of "board O" belonging to "group G4" is set to "4" and the production order of "board R" belonging to "group G5" is set to "5". . The production plan information PPI created by the production plan creation unit 453 is output (displayed) by the output unit 43 and transmitted to the mounting control device 3 via the data communication unit 41 . Upon receiving the production plan information PPI, the mounting control device 3 controls operations related to production of component-mounted boards in the mounter 2 based on the production plan information PPI.

Next, referring to FIG. 8C, a procedure for creating a production plan corresponding to the production request information PRI of FIG. 7C will be described. When the production request acquisition unit 452 acquires the production request information PRI of FIG. 7C, the production plan creation unit 453 reads the pre-registered group information RGI of FIG. Based on the requested production board type information PR1 and the registered board type information RG2, the production plan creating unit 453 determines whether or not there is a new board that is not registered in the registered board type information RG2. Since the production request board type information PR1 of the production request information PRI in FIG. 7C includes "board S", "board T" and "board U" which are not registered in the registered board type information RG2, 2, the production planning unit 453 grasps these "board S", "board T" and "board U" as new boards.

Then, the production plan creation unit 453 determines all of the "board A", "board B", "board D", "board O" and "board R" except for the new board indicated by the production request board type information PR1. is created based on the registered board type information RG2. In the example shown in FIG. 8C , the production plan creation unit 453 creates a first combination pattern CP1 consisting of a combination of “group G1” and “group G3” and “group G1” and “group G3” as combination patterns of pre-registered groups. A second combination pattern CP2 consisting of a combination of "G4" and "group G5", a third combination pattern CP3 consisting of a combination of "group G2" and "group G3", and "group G2" and "group G4". A fourth combination pattern CP4 made up of a combination with "group G5" is created.

When the creation of the first to fourth combination patterns CP1 to CP4 is completed, the production plan creation unit 453 creates combination patterns based on the evaluation element information RG4 of the pre-registered group information RGI and the production quantity information PR2 of the production request information PRI. The evaluation value is calculated for each of CP1 to CP4. Then, the production planning unit 453 selects the combination pattern with the smallest calculated evaluation value as the attention combination pattern ACP.

For example, assume that the evaluation value is the total production time TPT. In the production request information PRI of FIG. 7C, among the "board A", the "board B" and the "board D" indicated by the production request board type information PR1, the production quantity of the "board A" is the smallest at "10". , and the number of production of "substrate D" is extremely large at "100". Therefore, when comparing "group G1" and "group G2" as pre-registered groups to which "board A", "board B", and "board D" belong, the cycle time indicated by the cycle time information RG41 is the number of production units. "Group G2", which is the smallest for "board D" with a large number of "board D" and places the highest priority on the production efficiency of this "board D", is selected as a pre-registered group that constitutes the attention combination pattern ACP. On the other hand, in the production request information PRI of FIG. 7C, the production numbers of "board O" and "board R" indicated by the production request board type information PR1 are both "20", which is not so large. Therefore, when comparing the "group G3" as the pre-registered group to which the "substrate O" and the "substrate R" belong to and the combination of the "group G4" and the "group G5", the "substrate O" and the "substrate R" are grouped together, the "group G3" in which the number of setups SN is small and the setup work time ST is small is selected as a pre-registered group constituting the combination pattern ACP of interest. Therefore, the production plan creation unit 453 selects the third combination pattern CP3, which is a combination of "group G2" and "group G3", as the attention combination pattern ACP, corresponding to the production request information PRI of FIG. 7C.

In this case, the production planning unit 453 determines that the new "board S", "board T" and "board U" belong to the "group G2", and creates a new "group G2" including the new board. G2A” will be created. The production plan creation unit 453 creates pre-registered group information RGI for the new "group G2A".

The production plan information PPI created by the production plan creation unit 453 is output (displayed) by the output unit 43 and transmitted to the mounting control device 3 via the data communication unit 41 . Upon receiving the production plan information PPI, the mounting control device 3 controls operations related to production of component-mounted boards in the mounter 2 based on the production plan information PPI.

Next, the operation of the production planning device 4 will be described with reference to the flow chart of FIG. First, when the data communication unit 41 receives the production request information PRI, the production request acquisition unit 452 acquires the production request information PRI (step s1). Next, the production plan creation unit 453 sets search limit conditions and search continuation conditions based on the command regarding condition setting at the time of production plan creation input via the input unit 42 (step s2). The search limit condition is a condition indicating a limit on the number of pre-registered group combination patterns to be created. The search continuation condition indicates a condition for continuing the creation of combination patterns after the number of created combination patterns reaches the search limit condition. The search continuation conditions include the evaluation value calculation total time, the maximum number of search trials, and the degree of achievement of the evaluation value target. The evaluation value calculation total time indicates the total evaluation value calculation time for all combination patterns created so as to satisfy the search restriction conditions. The maximum number of search trials indicates the allowable maximum number of search repetitions for one set of combination patterns that satisfy the search restriction conditions. The evaluation value target achievement level indicates the achievement level of the evaluation values of all the combination patterns created so as to satisfy the search restriction conditions with respect to the target value.

When the production request acquisition unit 452 acquires the production request information PRI, the production plan creation unit 453 reads the pre-registered group information RGI from the group database 441 . Based on the registered board type information RG2, the production plan creation unit 453 creates a combination pattern of the pre-registered groups indicated by the group type information RG1 that includes all of the boards indicated by the production request board type information PR1. (step s3). At this time, the production plan creating unit 453 creates N combination patterns indicated by the search restriction conditions.

When the creation of N combination patterns based on the search restriction conditions is completed, the production plan creation unit 453 creates combinations based on the evaluation element information RG4 of the pre-registered group information RGI and the production quantity information PR2 of the production request information PRI. The evaluation values of the patterns are sequentially calculated (step s4). When the evaluation value of one combination pattern is improved (YES in step s5), the production plan creation unit 453 determines that the evaluation value of one combination pattern is higher than the evaluation value of the previous combination pattern. is smaller, the one combination pattern is selected as a combination pattern of interest ACP (step s6), and then the process proceeds to step s7. On the other hand, if the evaluation value of one combination pattern is not improved (NO in step s5), the production planning unit 453 skips step s6 and shifts the process to step s7.

In step s7, the production plan creating unit 453 determines whether or not the calculation of the evaluation values of the N combination patterns indicated by the search restriction conditions has been completed. If calculation of the evaluation values for the N combination patterns has not been completed (NO in step s7), each process from step s4 to step s6 is repeated. On the other hand, when the calculation of the evaluation values of the N combination patterns is completed (YES in step s7), the production plan creation unit 453 determines whether or not to continue the search based on the search continuation condition. (step s8). For example, when at least one of the evaluation value calculation total time, the maximum search trial count, and the evaluation value target achievement level as the search continuation condition does not reach the target value, the production plan creation unit 453 It is determined to continue the search, and each process from step s3 to step s7 is repeated. When it is determined not to continue the search (NO in step s8), the production plan creation unit 453 determines whether or not the new board is included in the production request board type information PR1 of the production request information PRI. (step s9). If the production request board type information PR1 does not include a new board, the production plan creation unit 453 shifts the process to step s10. If a new board is included in the production request board type information PR1, the production plan creation unit 453 executes grouping processing for the new board (step s91), and then proceeds to step s10.

At step s10, the production plan creating section 453 creates production plan information PPI indicating a production plan corresponding to the production request information PRI, based on the combination pattern ACP of interest selected in the process of step s6. The production plan information PPI created by the production plan creation section 453 is transmitted to the mounting control device 3 via the data communication section 41 . Upon receiving the production plan information PPI, the mounting control device 3 controls operations related to production of component-mounted boards in the mounter 2 based on the production plan information PPI.

As described above, according to the production plan creation device 4 according to the present embodiment, the production request information PRI including the production request board type information PR1 and the production quantity information PR2 regarding the board to be produced is sent to the production request acquisition unit. 452. Then, the production plan creating unit 453 creates a production plan corresponding to the production request information PRI based on the pre-registered group information RGI related to the pre-registered group indicating groups of multiple types of substrates. At this time, the production plan creation unit 453 selects a combination pattern that satisfies a predetermined condition for the evaluation value related to the production efficiency of the mounting machine 2 from among the combination patterns of the pre-registered groups indicated by the pre-registered group information RGI, and selects the combination pattern of interest ACP. , the production plan information PPI indicating the production plan is created. In other words, the production plan creating unit 453 does not create groups of a plurality of types of substrates and execute arithmetic processing such as analyzing the optimization of the feeder arrangement or the like for each group, as in the conventional technology. The production plan creation unit 453 uses the pre-registered group information RGI that has been registered in advance as it is to perform calculations for creating combination patterns of pre-registered groups and calculations for selecting the attention combination pattern ACP from among the combination patterns. It stops at executing the arithmetic processing including. For this reason, the processing time of the arithmetic processing of the production plan creating section 453 is greatly shortened compared to the arithmetic processing of analyzing the optimization of the feeder arrangement and the like for each group. As a result, in the mounting machine 2 that produces component-mounted boards corresponding to multiple types of boards, it is possible to improve overall production efficiency, including shortening the time required for arithmetic processing of the production planning device 4. becomes.

Further, the component mounting system 1 according to the present embodiment includes the production plan creating device 4 described above. According to this component mounting system 1, in the mounting machine 2 that produces component-mounted boards corresponding to a plurality of types of boards, overall production efficiency is improved, including reduction in the time required for arithmetic processing of the production plan creation device 4. Improvements can be made.
