Description

Production system

This specification discloses the production system.

Conventionally, in a mounting system such as mounting a component on a board, a system for determining whether or not a production plan can be executed is known (see, for example, Patent Document 1). In this system, the feeder unit determines whether the remaining number of those parts is sufficient based on the type and quantity of parts to be mounted, and predicts the need for maintenance of the feeder unit that supplies the parts. By determining the possibility of shortage, the feasibility of executing the production plan is determined.

By the way, there is a system in which an execution system that executes production such as the above-mentioned mounting system and a plan creation system that creates a production plan are separately configured. In such a configuration, it is difficult for the planning system to grasp the status of the members used for production such as the feeder unit and make the above-mentioned judgment, so that it is not possible to create an appropriate plan. There is. In that case, even if it becomes clear that the number of remaining parts is insufficient or the need for maintenance is found during the execution of production, the parts that need to be supplied may not be prepared in time, which may affect the production.

In the production system of the present disclosure, the execution system executes a simulation of the production process based on the production schedule of the substrate to derive the supply timing at which the parts need to be supplied during the production process. In addition, the planning system creates a plan for the preparation process for preparing the members to be supplied in time for the derived supply timing. Therefore, if the member to be supplied is prepared according to the preparation process, the member can be supplied in time for the supply timing. Therefore, it is possible to prevent the production from being affected by the delay in the supply of the members and to create an appropriate plan for the production as planned.

The following is a description of the processing of the APS system 20 and the mounting system 30 of the production system 1 thus configured. FIG. 3 is a sequence showing an example of processing of the APS system 20 and the mounting system 30. The processing of the APS system 20 is executed by the APS management device 21, and the processing of the mounting system 30 is executed by the mounting management device 31. First, the APS system 20 transmits the production information based on the production schedule generated by the ERP system 10 to the mounting system 30 (S100). Further, the APS system 20 transmits an instruction for deriving the supply timing of the feeder 70 required in the mounting process based on the production information to the mounting system 30 (S110).

FIG. 4 is an explanatory diagram showing an example of production information. As shown in the figure, the production information defines the order name (for example, WO1), the number of boards SN which is the number of boards produced, the number of parts which is the planned number of parts P to be mounted per board, and the like. .. The number of parts is determined for each part type, for example, the number of parts Na of the part type A and the number of parts Nb of the part type B, and the total number of parts PN is determined. Although not shown, the production information includes the arrangement position of each component on the substrate S and the like. In S100, the number of boards SN, the type of parts to be mounted, the number of parts N, and the like are included in the production information and transmitted.

When the mounting system 30 receives the production information and the instruction for deriving the supply timing of the feeder 70 from the APS system 20, the mounting system 30 acquires the feeder information of each feeder 70 attached to the mounting device 50 (S200). FIG. 5 is an explanatory diagram showing an example of feeder information. Note that FIG. 5 illustrates feeder information of one mounting device 50, but similar feeder information is acquired for each mounting device 50. As shown in the figure, for each feeder 70 set in each slot of the supply unit 53 of the mounting device 50, the component type, identification information, the remaining number R of the component P, the number of feeds F, and the like are acquired. The control unit (not shown) of each feeder 70 decrements the remaining number R by a value of 1 and increments the feed count F by a value of 1 each time the feeder 70 supplies the component P. The mounting control unit 51 can acquire the remaining number R and the number of feeds F via communication with the control unit of each feeder 70, and the mounting management device 31 of the mounting system 30 obtains the remaining number R and the number of feeds F. Obtained from the mounting control unit 51. The feeder 70 is determined to require maintenance based on the fact that the number of feeds F has reached a predetermined reference number of times (predetermined value), and maintenance by the worker M or maintenance by the maintenance device is performed.

Next, the mounting system 30 executes a simulation of the mounting process based on the production information and the feeder information (S210). Further, the mounting system 30 derives the supply timing and the recovery timing of the feeder 70 due to the out of parts by executing the simulation (S220), and derives the supply timing and the recovery timing of the feeder 70 due to the maintenance (S230). FIG. 6 is an explanatory diagram showing an example of the derivation result of the mounting system 30. Here, in the simulation of S210, the transfer time to the arrangement position of each component P supplied from the feeder 70 is based on the component type and the number of components, the arrangement position of each component, the component type and slot position of the feeder 70, and the like. A cycle time CT for mounting a component having the number of components PN on one substrate S is calculated. Further, the mounting system 30 calculates the process time of the production order (for example, WO1) by multiplying the cycle time CT per board S by the number of boards SN (see FIG. 6). Each timing of t1 to t10 in FIG. 6 is a relative timing with the start of the mounting process as a reference (t1). It is assumed that the mounting system 30 stores the production record of the board S in association with the production information, and when the production record related to the newly received production information is stored, the cycle time based on the production record is stored. CT may be used, or the calculated cycle time CT may be adjusted based on the production results.

Further, in the simulation, it is determined whether or not a feeder 70 that is out of parts is generated based on the component type and the number of components N per substrate S and the component type and the remaining number R of each feeder 70. To. Further, for the feeder 70 which is out of parts, the estimated time from the start of the mounting process to the out of parts is calculated based on the cycle time CT. In S220, the mounting system 30 derives the estimated time as the supply timing of the new feeder 70 due to the out-of-parts (for example, t4 in FIG. 6), and also derives the recovery timing to collect the out-of-parts feeder 70 (for example, t4 in FIG. 6). For example, t5 in FIG.

Further, in the simulation, the component type and the number of components N per board S, the component type and the feed count F of each feeder 70, the scheduled feed count based on the component count N, and the maintenance reference count are used. , It is determined whether or not the feeder 70 that requires maintenance is generated. For the feeder 70 that requires maintenance, the estimated time from the start of the mounting process to the need for maintenance is calculated based on the cycle time CT. In S230, the mounting system 30 derives the estimated time as the supply timing of the new feeder 70 associated with maintenance (for example, t7 in FIG. 6), and also derives the recovery timing at which the feeder 70 requiring maintenance should be recovered. (For example, t8 in FIG. 6).

If the mounting system 30 determines that the feeder 70 of the required component type is not set based on the feeder information (for example, component type D in FIG. 6), the mounting process determines the supply timing of the feeder 70 of that component type. (For example, t1 in FIG. 6). Further, if there is an unnecessary component type feeder 70 to be recovered with the supply of the feeder 70, the mounting system 30 derives the recovery timing (for example, t2 in FIG. 6). The mounting system 30 transmits the simulation results such as the supply timing, the recovery timing, and the process time derived in this way to the APS system 20 (S250).

The APS system 20 creates a plan for the preparation process of the feeder 70 by reflecting the supply timing received from the mounting system 30 so as to back-calculate each work time required for supplying the feeder 70 (S120). FIG. 7 is an explanatory diagram showing an example of a plan for the preparation process of the APS system 20. As shown in the figure, the working time includes the taking-out time (a) for taking out the reel 75 from the storage device 60, the carrying time (b) for transporting the reel 75 to the work area A2, and the assembly for assembling the reel 75 to the feeder 70. There is a time (c) and a transportation time (d) for transporting the feeder 70 to the production area A1. The APS system 20 sets the timing of each work by back-calculating each work time (d), (c), (b), (a) from the supply timing (see the arrow in FIG. 7). Further, the APS system 20 determines the start date and time (T5 in FIG. 7), which is the start date and time of the order WO1 (t1 in FIG. 6), based on the production status of the mounting system 30, and the start date and time and each set. Each work date and time T1 to T14 is determined based on the work timing.

Further, the APS system 20 reflects various times associated with the collection of the feeder 70 in the preparation plan from the collection timing received from the mounting system 30 (S130). As shown in FIG. 7, the collection time (e) for collecting the feeder 70 from the production area A1 to the work area A2, the time (f) for maintenance in the work area A2 as necessary, and the time from the feeder 70 in the work area A2. The transportation time (g) for transporting the removed reel 75 to the storage area A3 and storing it in the storage device 60 is reflected in the preparation plan. The maintenance time (f) is reflected when the feeder 70 that requires maintenance is collected. The APS system 20 instructs the worker M to work on the preparatory process by displaying (outputting) the plan of the preparatory process thus created on the display unit 27 or the like (S140), and ends the process. The worker M can prepare the feeder 70 in time for the supply timing by preparing the necessary feeder 70 based on the plan of the preparation process displayed on the display unit 27. In addition to the display unit 27, the plan for the preparation process may be displayed on other display units such as the operation panel 58 of the mounting device 50, the operation panel 62 of the storage device 60, and the display unit of the mobile terminal of the worker M. ..

Here, the correspondence between the constituent elements of the present embodiment and the constituent elements of the present invention will be clarified. The implementation system 30 of the present embodiment corresponds to the execution system of the present disclosure, the APS system 20 corresponds to the planning system, and the production system 1 corresponds to the production system.

In the production system 1 described above, the mounting system 30 executes a simulation of the mounting process based on the production schedule of the substrate S to derive the supply timing of the feeder 70 (reel 75). In addition, the APS system 20 creates a preparatory process plan for preparing the feeder 70 in time for the derived supply timing. Therefore, if the feeder 70 to be supplied is prepared according to the preparation process, the supply of the feeder 70 can be made in time for the supply timing. Therefore, it is possible to prevent the supply delay of the feeder 70 from causing an influence such as waiting for supply of parts.

Further, the APS system 20 calculates back from the supply timing the take-out time when the reel 75 is taken out from the storage device 60, the transportation time when the reel 75 is transported, the assembly time when the reel 75 is assembled to the feeder 70, and the like. Create a plan for the preparation process by reflecting on. Therefore, the time required for preparing the feeder 70 (reel 75) can be reflected in the plan of the preparation process without excess or deficiency, and the feeder 70 can be reliably supplied at the supply timing.

Further, the mounting system 30 derives the timing of component shortage as the supply timing by executing a simulation using the remaining number R of the components of the feeder 70 and the number of components N to be mounted. Therefore, it is possible to reliably prevent the production from being affected by the shortage of parts.

Further, the mounting system 30 derives the maintenance timing of the feeder 70 as the supply timing by executing the simulation using the feed count F of the feeder 70 and the scheduled feed count based on the number of components N to be mounted. Therefore, it is possible to reliably prevent the production from being affected by maintenance.

Further, since the APS system 20 creates a plan for the preparation process including the collection of the feeder 70, the recovery of the feeder 70 can be efficiently performed according to the preparation process. In addition, maintenance and other operations can be reliably performed before the collected feeder 70 is used next time.

It should be noted that the present disclosure is not limited to the above-described embodiment, and it goes without saying that the present disclosure can be carried out in various embodiments as long as it belongs to the technical scope of the present disclosure.

For example, in the above-described embodiment, both the timing of parts shortage and the timing of maintenance are set as supply timings, but the present invention is not limited to this, and the preparation process is planned with either one (for example, the timing of parts shortage) as the supply timing. You may create it. Further, regarding maintenance, the timing before the timing when maintenance is required may be the supply timing of the feeder 70.

FIG. 8 is a sequence showing the processing of the APS system 20 and the mounting system 30 of the modified example. In the modified example, the same process as that of the embodiment is assigned the same step number, and the description thereof will be omitted. In this modification, when the APS system 20 receives the feeder supply timing from the mounting system 30, the supply timing and the recovery timing of the feeder 70 for maintenance are set at the start of mounting (S115), and the subsequent processing is executed. That is, the start timing of the mounting process prior to the original maintenance timing is defined as the supply timing and the recovery timing. As a result, the feeder 70, which requires maintenance during the mounting process, can be prepared and replaced in advance before the start of the mounting process. Therefore, it is not necessary to prepare the feeder 70 for maintenance during the mounting process, so that the burden of the preparation work during the mounting process can be reduced.

Further, for example, the processing of this modification may be performed when the maintenance timing of the feeder 70 overlaps with the timing of parts shortage or the timing of maintenance of another feeder 70. That is, when the maintenance timing does not overlap with other supply timings, the maintenance timing is set as the supply timing without changing, and when the maintenance timing overlaps with other supply timings, the start timing of the mounting process, etc. The preparation process may be planned so that the supply timing is set before the maintenance timing.

In the above-described embodiment, the maintenance timing is determined based on the number of times the member is used, such as the number of feeds F of the feeder 70, but the present invention is not limited to this, and the maintenance timing may be determined based on the usage time of the member.

In the above-described embodiment, the preparation process plan includes the time required for collecting the feeder 70 and the maintenance associated with the collection, but the time required for preparing the feeder 70 is not limited to this (the upper item in FIG. 7). It is not necessary to create a plan for the preparation process and include the time required for collection (items in the lower part of FIG. 7).

In the above-described embodiment, the production system 1 includes three systems, an ERP system 10, an APS system 20, and a mounting system 30, but the production system 1 is not limited thereto. The production system 1 is provided with at least an execution system for executing the production process of the substrate S using production members and a plan creation system for creating plans for various processes based on the production schedule of the substrate S. good. For example, the production system 1 may include a planning system including the functions of the ERP system and the functions of the APS system, and the mounting system 30.

In the above-described embodiment, the worker M has performed the work of the preparation process, but the present invention is not limited to this. For example, when the production system 1 is configured to automatically perform the preparation work of the feeder 70 (reel 75) by an automatic guided vehicle, an automatic assembly device, or the like, each control unit of the automatic guided vehicle or the automatic assembly device. You may send the plan of the preparatory process to etc. to perform the work.

Here, the production system of the present disclosure may be configured as follows. In the production system of the present disclosure, the planning system has a time for taking out the member to be supplied from a predetermined storage unit for storing the member and a time for performing work for making the member usable in the execution system. And the time for transporting the member to the execution system may be reflected so as to be calculated back from the supply timing to create a plan for the preparation process. By doing so, the time required for the preparation of the members can be reflected in the plan of the preparation process without excess or deficiency, so that the members can be reliably supplied at the supply timing.

In the production system of the present disclosure, the member is a member that accommodates a plurality of parts mounted on the substrate and sequentially sends out and supplies the parts, and the execution system is a balance of the parts housed in the member. By executing the simulation using the number and the planned number of parts to be mounted based on the production schedule, the timing at which the member runs out during the production process may be derived as the supply timing. By doing so, it is possible to surely prevent the production from being affected even if the parts of the members are cut off during the production process.

In the production system of the present disclosure, the member is a member that requires maintenance when the number of times of use or the time of use reaches a predetermined value, and the execution system has the number of times of use or the time of use of the member and the production schedule. By executing the simulation using the planned number of times of use or the scheduled time of use of the member based on the above, the timing at which maintenance of the member is required during the production process may be derived as the supply timing. By doing so, even if maintenance of the members is required during the production process, it is possible to surely prevent the production from being affected.

In the production system of the present disclosure, the planning system prepares the parts requiring maintenance during the production process in time for the start timing of the production process before the derived supply timing. It may be used to create a process plan. In this way, the parts that require maintenance during the production process can be prepared and replaced in advance before the start of the production process. Therefore, since it is not necessary to replace the members during the production process due to maintenance, the burden of the preparatory work during the production process can be reduced.

In the production system of the present disclosure, the planning system creates a plan for the preparatory process, including collection of the members that are no longer needed in the execution system because they are replaced with the members supplied at the supply timing. You may do it. By doing so, the members can be efficiently collected according to the preparation process. In addition, it is possible to proceed with work such as maintenance of the members before the collected members are supplied next time.

This disclosure can be used for a production system including a production process execution system and a process planning system.
