The RAM 53 stores component data indicating components and the relationship between the components and the component feeder 40, component arrangement data described later, and the like.

FIG. 4 shows arrangement data PD of components (component feeder 40) necessary for producing a plurality of board types. In FIG. 4, production of a board of the board type to be produced first (hereinafter referred to as production job N). In the production of a board using the parts a, b, c, and d, and in the production of a board of the board type to be produced next (hereinafter referred to as production job N + 1), a, b, d, An example in which a board is produced using e, and a board is produced using the parts a, b, and f in the production of a board of the board type to be produced next (hereinafter referred to as production job N + 2). Is shown.

First, the component feeder 40 that accommodates the components a, b, c, and d used in the first production job N in four slots (for example, 42A to 42D) of the slots 42A to 42E of the component mounter 10. Is determined to be placed. In the next production job N + 1, a, b, d among the parts to be used are common to the production job N, and only e is a different part. Therefore, the parts feeder 40 containing the part e is set in an empty slot (for example, , 42E). Similarly, in the production job N + 2, since only the part f is different from the part used in the production job N + 1, it is determined that the part feeder 40 that accommodates the part f is arranged in the slot 42C.

That is, while the production job N + 1 is being executed, there is no empty slot, but it is possible to remove the component feeder 40 that accommodates the component c used only in the production job N that has already completed production at that time. It is determined that the component feeder 40 accommodating the component f is arranged in the slot 42C from which the component feeder 40 accommodating the component c is removed.

In this way, the arrangement position of the parts feeder 40 in each production job N to N + 2 is determined based on the production plan, and the part arrangement data PD as shown in FIG. 4 is created. Based on the part placement data PD, the controller 50 instructs to place the part feeder 40 containing the parts used in the next production job during the execution of the production job currently being produced. The person mounts the specified component feeder 40 at the determined slot position.

FIG. 5 shows a flowchart executed by the CPU 51 for creating the component arrangement data PD described above. This flowchart is processed prior to executing the first production job N based on the production plan. The The RAM 53 of the control device 50 stores mounting position data indicating which slot 42 of the component supply device 12 is mounted with which type of component feeder 40 is mounted. The component feeder 40 is removed from the slot 42 or rewritten whenever the component feeder 40 is mounted in the slot 42.

First, in step 100, based on the part data stored in the ROM 52 of the control device 50, the difference between the part used in the production job N currently being produced and the part used in the production job N + 1 to be produced next is obtained. Then, a part (part e in FIG. 4) used only in the production job N + 1 to be produced next is calculated. Next, in step 102, the parts feeder 40 that contains parts used only in the production job N + 1 to be produced next is searched.

Next, in step 104, it is determined whether or not there is an empty slot in which the parts feeder 40 that accommodates parts used in the production job N can be placed. In the first production job N, since the slots 42A to 42E of the parts feeder 40 are all empty, the determination result in step 104 is YES, and the parts a to d used in the production job N in the next step 106. Is determined to be placed in the empty slots 42A to 42D of the part feeder 40 (part feeder 40 retrieved in step 102).

Next, in step 108, it is determined whether or not the production job N is the last production job. If the determination result is YES, the process ends. In this case, the determination result is NO. After 1 is added to the production job N (N = N + 1), the process returns to step 100 and the process of step 100 described above is executed.

In this case, since 1 is added to the production job N, in step 100, the difference between the parts used in the next production job N + 1 and the parts used in the next production job N + 2 is obtained. The parts used only in the production job N + 2 (part e in FIG. 4) are calculated, and in step 102, the parts feeder 40 containing the parts used only in the next production job N + 2 is searched.

Next, in step 104, it is determined whether or not there is an empty slot in which the part feeder 40 that accommodates the part e used in the production job N + 1 can be placed. In this case, since the slot 42E is in an empty state, the determination result in step 104 is YES, and in the next step 106, the parts feeder 40 containing the part e used in the production job N + 1 is placed in the empty slot 42E. Decide to do.

In this way, the arrangement position of the component feeder 40 in each production job is determined. However, when determining the arrangement of the component feeder 40 containing the component f used in the production job N + 2, there is no empty slot. The result of determination in step 104 is NO, and the routine proceeds to step 110. In step 110, when the parts feeder 40 used in the production job (N + 1) is left and the parts feeder 40 containing the unused parts is removed, the parts feeder 40 used in the production job N + 2 can be arranged. If the determination result is YES, the process proceeds to step 112. If the determination result is NO, the process proceeds to step 114.

That is, when the parts feeder 40 used in the production job N + 2 is actually placed in the empty slot in the parts supply device 12, the production job N + 1 is being executed. For this reason, if the parts feeder 40 used in the production job N + 2 can be arranged by removing the parts feeder 40 containing the part (c) used in the production job (before N) whose production has already been completed, step 112 is performed. Then, it is determined that the parts feeder 40 that is not used in the production job N + 1 is removed from the slot 42C and replaced with the parts feeder 40 that is used in the production job N + 2.

In other words, in the parts feeder 40 that contains the parts used in the production job N, the parts feeder 40 that is not common to the parts feeder 40 that contains the parts used in the production job N + 1 is replaced with the parts used in the production job N + 2. Among the accommodated component feeders 40, a component feeder 40 that is not common to the component feeder 40 that accommodates components used in the production job N + 1 is arranged in the feeder mounting portion 41.

However, if the determination result in step 110 is NO, in step 114, it is determined that only the component feeders 40 that can be arranged are arranged among the component feeders 40 used in the production job N + 2, and then the process proceeds to step 108. To do. Of the component feeders 40 used in the production job N + 2, the component feeders 40 that could not be arranged are unavoidably arranged after the completion of the production job N + 1.

Step 100 described above constitutes a difference calculation means for obtaining the difference between the part used in the production job (N) currently being produced and the part used in the production job (N + 1) to be produced next. Thus, a search means for searching for a part feeder 40 that contains parts used only in the next production job (N + 1) to be produced based on the difference obtained by the difference calculation means 100 is constructed. An arrangement position determining means for determining an arrangement position so as to arrange the component feeder 40 retrieved by the means 102 in the slot 42 of the component supply apparatus 12 is configured.

Further, after determining the arrangement position of the component feeder 40 in the above-described step 210, the arrangement position of the component feeder 40 between the component mounting machines 10A to 10C so as to balance the production time in the plurality of component mounting machines 10A to 10C. The arrangement position exchanging means for exchanging is configured.

As a result, as shown in FIG. 4, component arrangement data PD on how to arrange the components (component feeder 40) in each production job N, N + 1, N + 2 is created and stored in the RAM 53 of the control device 50. Is done. Based on the part placement data PD, the worker is instructed to place the part feeder 40 when the production job is executed, and the part feeder 40 is replaced.

That is, when the first production job N is executed, the parts feeders 40 containing the parts a to d used in the production job N are respectively inserted into the slots 42A to 42D of the parts supply device 12 as shown in FIG. An operator is instructed to display them by displaying them on the display device 61. Then, during the execution of the first production job N, as shown in FIG. 6B, the component feeder 40 that accommodates the component e used in the production job N + 1 is arranged in the slot 42E of the component supply device 12. Instruct workers. Similarly, during the execution of the next production job N + 1, the part feeder 40 that accommodates the part f used in the production job N + 2 is arranged in the slot 42C of the part supply apparatus 12 as shown in FIG. 6C. Instruct the worker.

As a result, the part feeder 40 used in the next production job N + 1 can be replaced while the production job N currently being produced is being executed. As a result, it is not necessary to change the component feeder 40 when switching the production job, and the production job can be switched only by changing the mounting program, etc., and the component mounter 10 can be stopped by changing the setting. Can be minimized.

Further, even when all of the parts feeders 40 used in the production job N + 1 (N + 2) to be produced next cannot be arranged, when the parts feeder 40 used in the production job N (N + 1) is removed when the production job is changed, Since only a part of the component feeders 40 needs to be replenished, the stoppage of the component mounter 10 due to the setup change can be greatly shortened compared to the conventional case.

If the component feeder 40 containing the components to be used in the next production job (N + 1) is arranged in the slot 42 of the component supply device 12 and there is still an empty slot, the following is further performed. You may make it arrange | position the parts feeder 40 used with the production job (N + 2) produced next.

According to the first embodiment described above, during execution of a production job that is currently being produced, it is used in a production job that is currently being produced out of the component feeders 40 that contain the parts that were used in the production job produced previously. The part feeder 40 containing the parts used in the production job currently being produced out of the parts feeders 40 containing the parts used in the production job to be produced next instead of the parts feeder 40 not common to the parts feeder 40 containing the parts. Since the component feeder 40 that is not common to the feeder is arranged in the feeder mounting portion 41, it is possible to suppress the stop of the component mounting machine 10 due to the changeover of the component feeder 40 when the production job is changed, and to execute the production job currently being produced It is no longer necessary to replace the common part feeder 40 with the part feeder 40 used in the previously produced production job. It is possible to improve the productivity of the component mounting.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, during the execution of the production job N that is currently being produced, the parts feeder 40 that contains the parts to be used in the production job N + 1 to be produced next is arranged in the parts supply device 12. Although it is the same as that of the embodiment, in the mounting line provided with a plurality of component mounters, the arrangement of the component feeders 40 in which the cycle times in the plurality of component mounters are balanced can be realized.

In the second embodiment, as shown in FIG. 7, a plurality of

component mounters

10A, 10B, and 10C each provided with the same component supply device 12 as described in the first embodiment are provided. A substrate transfer device 13 for transferring the substrate B is disposed between the mounting

machines

10A, 10B, and 10C. The component feeders 40 are sequentially arranged in the plurality of slots 42 of the component supply apparatuses 12 of the plurality of

component mounting machines

10A, 10B, and 10C based on the production plan. The production time between 10B and 10C is considered to be optimum (minimum).

FIG. 8A shows the component placement data PD1, and in FIG. 8A, the production jobs N, N + 1 are respectively inserted into the five slots 42A to 42E of the three

component mounting machines

10A, 10B, and 10C. , An example in which component feeders 40 that accommodate components A to M used in N + 2 are sequentially arranged is shown. That is, in the same manner as described in the first embodiment, the component feeder 40 that accommodates the components A, D, G, and J used in the first production job N is replaced with the slots 42A to 42A of the first component mounting machine 10A. It is decided to arrange in 42D. Similarly, in the second and third

component mounting machines

10B and 10C, the component feeder 40 that accommodates the components B, E, and H and the components C, F, and I used in the first production job N is provided in each slot. It is decided to arrange in 42A to 42C.

Subsequently, among the parts used in the next production job N + 1, the part feeder 40 accommodating the part M different from the above is disposed in the

slots

42E and 42D of the first and third

part mounting machines

10A and 10C. Among the parts used in the next production job N + 2, it is determined that the part feeder 40 containing the part K is to be placed in the slot 42D of the second component mounting machine 10B.

When the arrangement of the component feeders 40 necessary for the production jobs N to N + 2 is determined in this way, the production time of each of the component mounting machines 10A to 10C necessary for executing the production jobs N to N + 2 is subsequently determined. That is, the production times TA, TB, and TC obtained by multiplying the cycle time per substrate by the number of substrates produced are calculated for each production job N to N + 2. Of these production times TA, TB, and TC, the longest production times T1, T2, and T3 are obtained for each production job N to N + 2, and the longest production times T1, T2, and T3 are controlled. It is stored in the RAM 53 of the device 50.

That is, when the production time of the second component mounter 10B among the first to third component mounters 10A to 10C is the longest in executing the production job N (N + 1, N + 2), The production time of the second component mounter 10B is stored as the longest production time T1 (T2, T3). Then, a process for optimizing (minimizing) the longest production times T1, T2, and T3 is executed.

FIG. 9 is a flowchart showing a process for optimizing the longest production times T1, T2, and T3. This process is executed following step 108 of the flowchart described above. Steps 100 to 114 are the same as those in the previous embodiment, and will be omitted.

First, in step 200, as described above, the production times TA to TC in all the component mounting machines 10A to 10C are calculated for each of the production jobs N to N + 2, and the longest production times T1 to T3 are calculated as the production jobs N to N, respectively. It is calculated every N + 2 and stored in the RAM 53 of the control device 50.

Next, the process proceeds to step 204 through step 202 described later. In step 204, two component mounters (for example, 10A and 10B) are selected from the plurality of component mounters 10A to 10C, and these two component mounters are selected. One slot (for example, 42A and 42A) is selected from the mounting machines. Thereafter, in step 206, the longest production times T1a and T2a when the two component feeders 40 determined to be arranged in the two slots are replaced as shown in FIG. Judge whether or not to improve. The improvement of the production time means that the longest production time is shortened and the production times of the plurality of component mounting machines 10A to 10C are balanced.

If the decision result in the step 206 is YES, in the next step 208, the component arrangement data PD1 is rewritten to the component arrangement data PD2 as shown in FIG. 8B. However, if it does not decrease (if the determination result is NO), the process returns to step 202 without rewriting the component arrangement data PD1, and in step 204, the combination of the two slots is sequentially changed (for example, 42A and 42B, 42A and 42C...), And the above steps are repeated.

Thus, when it is determined in step 202 that all combinations have been completed, the process proceeds to step 210, and the component placement data PD2 at that time balances the production times of the plurality of component mounters 10A to 10C. For this purpose, it is stored in the RAM 53 of the control device 50 as the best component arrangement data.
