Based on the product information 43a and the preparation plan 43b, the preparation instruction unit 41 of the preparation work management device 7 includes a work terminal T possessed by the worker W who performs the preparation work, parts related to the production work (work processing), and the like. A preparation instruction 43c for instructing the preparation work is created on the preparation work body such as the transport vehicle V that conveys the members. The created preparation instruction 43c is stored in the preparation storage unit 43, and is transmitted to the corresponding work terminal T and the transport vehicle V by the preparation radio communication unit 7a.

Further, the preparation instruction 43c is transmitted to the placement work support device 4 (preparation work body) by the preparation communication unit 40. Further, the preparation communication unit 40 transmits the created preparation instruction 43c to the production control device 3. The number issuing unit 11 of the production control device 3 associates the received preparation instruction 43c with the order number based on the production order information 15a, and stores the order number based on the production order information 15a in the management storage unit 15 as the preparation instruction information 15c (see FIG. 4). That is, the preparation instruction information 15c is given to the preparation instruction 43c for instructing the preparation work body (work terminal T, transport vehicle V, arrangement work support device 4) for the preparatory work for processing the work (parts are mounted on the substrate). Information (order number) that identifies is linked.

As a method of associating the work-identifying information (order number) with the preparation instruction 43c, a unique number for identifying the work may be added to the preparation instruction 43c, or a conversion table is held and the information is virtually linked. You may attach it. The information that identifies the work (order number) and the unique number that identifies the work may not be the same but may be different.

In FIG. 3, the preparation record collection unit 42 of the preparation work management device 7 collects the preparation record 43d from the preparation work bodies such as the work terminal T, the transport vehicle V, and the arrangement work support device 4, and stores the preparation record 43d in the preparation storage unit 43. .. For example, as the preparation record 43d, the work of removing the tape feeder and parts from the trolley 5 as the external setup work, the work of storing, and the work of installing the work are prepared in the preparation instruction 43c. The information to be specified is associated and stored. Further, the preparation record 43d may include information on the worker W who has performed the external setup work.

The information acquisition unit 10 of the production control device 3 associates the received preparation record 43d with an order number based on the production order information 15a, and stores the received preparation record information 15e in the management storage unit 15 (see FIG. 4). That is, in the preparation record information 15e, the information (order number) for specifying the work is associated with the preparation record 43d of the preparation work body (work terminal T, transport vehicle V, arrangement work support device 4) for the work (board). ing.

In FIG. 3, the progress management unit 12 of the production control device 3 includes a progress difference calculation unit 12a as an internal processing unit. The progress difference calculation unit 12a calculates the progress difference between the production plan 23g and the production record 34d based on the production plan information 15f and the production record information 15d. For example, the progress difference calculation unit 12a specifies the progress difference between the planned and actual date and time when the board is collected by the board recovery devices M8 of the component mounting lines L1 to L3 by the order number and the board number. Calculated for each. Similarly, the progress difference calculation unit 12a calculates the progress difference between the preparation plan 23h and the preparation record 43d based on the preparation plan information 15g and the preparation record information 15e.

The progress management unit 12 manages the production progress of the substrate (work) based on the calculated progress difference. For example, the progress management unit 12 indicates that the progress is smooth when the progress difference between the production plan 23g and the production record 34d is within a predetermined difference, or when the progress difference between the preparation plan 23h and the preparation record 43d is within a predetermined difference. to decide. Further, the progress management unit 12 determines that the progress difference between the production plan 23g and the production record 34d is larger than the predetermined difference (production delay), or the progress difference between the preparation plan 23h and the preparation record 43d is larger than the predetermined difference (preparation). (Delay), it is judged that the progress is delayed and the plan needs to be revised.

In the progress management unit 12, even if the production record 34d is ahead of the production plan 23g and the preparation record 43d for the next production (lot) is progressing smoothly, the trolley 5 to be replaced cannot be prepared in time. If there is a possibility that any of the component mounting lines L1 to L3 will stop before the start of production, it is determined that the plan needs to be revised. That is, the progress management unit 12 not only shows the progress difference between the production plan 23g and the production record 34d and the progress difference between the preparation plan 23h and the preparation record 43d, but also the relative progress difference between the production record 34d and the preparation record 43d having the same order number. Judge whether or not the plan needs to be revised.

In FIG. 3, when the progress management unit 12 determines that the progress management unit 12 needs to revise the plan, the instruction changing unit 14 of the production control device 3 instructs the production planning device 6 to revise the production plan and the preparation plan. At that time, the information transmission unit 13 transmits the production record information 15d and the preparation record information 15e necessary for modifying the plan to the production plan planning device 6. The planning communication unit 20 of the production planning device 6 stores the received production record information 15d and preparation record information 15e in the planning storage unit 23 as the production record 23i and the preparation record 23j. The planned communication unit 20 may acquire the production record 23i from the line management devices B1, B2 or B3, and the preparation record 23j from the preparation work management device 7.

In addition to the order information 23a, the product information 23b, the line configuration information 23c, the member information 23d, and the trolley information 23e, the correction plan planning unit 22 of the production plan planning device 6 has a production record 23i and a preparation record 23j. A simulation is executed based on the above, and a modified production plan 23k and a modified preparation plan 23m are created (planned). The created modified production plan 23k and modified preparation plan 23m are stored in the planning storage unit 23. For example, in the modified production plan 23k, the production order of the component mounting lines L1 to L3 and lots X1 to X10 for producing the mounting board is changed (modified). Further, in the correction preparation plan 23m, the number of workers W, the order of the preparation work, the trolley groups Z1 to Z6 to be prepared, and the like are changed (updated).

In FIG. 3, the planning communication unit 20 transmits the created correction production plan 23k and correction preparation plan 23m to the production control device 3. The number issuing unit 11 of the production control device 3 associates the received correction production plan 23k and the correction preparation plan 23m with the order number based on the production order information 15a, and manages and stores the correction production plan information 15h and the correction preparation plan information 15i. Store in 15. As a result, the production progress of the lot whose plan has been revised in the production control device 3 is managed based on the revised production plan information 15h and the revised preparation plan information 15i.

Further, the planning communication unit 20 transmits the created modified production plan 23k to the line management device B1, B2 or B3 in charge. The off-line communication unit 30 of the line management device B1, B2 or B3 in charge stores (updates) the received modified production plan 23k as the production plan 34b in the line storage unit 34. As a result, the line management device B1, B2 or B3 in charge executes the management of the production work based on the modified production plan 34b. Further, the planning communication unit 20 transmits the created correction preparation plan 23m to the preparation work management device 7. The preparation communication unit 40 of the preparation work management device 7 stores (updates) the received correction preparation plan 23m in the preparation storage unit 43 as the preparation plan 43b. As a result, the preparatory work management device 7 manages the preparatory work based on the modified preparatory plan 43b.

In this way, the progress management unit 12 of the production control device 3 identifies the work (board) with the production instruction information 15b, the preparation instruction information 15c, the production record information 15d, and the preparation record information 15e acquired by the information acquisition unit 10. Manage the production progress of the work by associating it with the information to be used. Then, the instruction changing unit 14 of the production control device 3 issues a plan change instruction to the production planning device 6 based on the progress difference, so that the production work body (parts mounting device M3) by each of the line management devices B1 to B3 is issued. The production instruction 34c to the production equipment including M6 or the preparation instruction 43c to the preparation work body (work terminal T, transport vehicle V, arrangement work support device 4) by the preparation work management device 7 is changed.

Next, an example of production progress management by the production control device 3 will be described with reference to FIGS. 6 and 7. FIG. 6 is an explanatory diagram of an example of the smooth production progress of the mounting board based on the production plan and the preparation plan drafted by the component mounting system 1. FIG. 7 is an explanatory diagram of an example in which a delay occurs in the production progress of the mounting board based on the production plan and the preparation plan devised by the component mounting system 1. 6 and 7 show the situations of the present time 1 in which the production progress has progressed and the current state 2 in which the production progress has further progressed, respectively, with respect to the planned production plan 23 g and the preparation plan 23h shown in FIG. The shaded area in the figure indicates that the production work or preparatory work has been completed (partially completed).

In FIG. 6, at present, the production progress of the lot X2 being produced on the component mounting line L1 is ahead of the production plan of 23 g. Further, the production progress of the lot X3 during the production work on the component mounting line L2 is slightly behind the production plan of 23 g. Further, the production of the lot X1 on the component mounting line L3 has been completed according to the production plan of 23 g. Further, in the preparation area As, the preparatory work of the preparatory work numbers Y1 to Y4 is completed, and the preparatory work of the preparatory work number Y5 is proceeding according to the preparatory plan 23h. Therefore, the progress management unit 12 determines that all the production work and the preparatory work are in good condition based on the progress difference calculated by the progress difference calculation unit 12a.

In FIG. 7, at present 2, the production work of lot X5 on the component mounting line L1 and lot X6 on the component mounting line L2 is proceeding according to the production plan 23 g. In addition, the preparatory work is progressing according to the preparatory plan 23h, and the preparatory work for the bogie group Z1 of the preparatory work number Y7 has been completed. However, the production work of the lot X4 on the component mounting line L3 is significantly delayed from the production plan of 23 g. The next planned preparatory work is the preparatory work for the bogie group Z4 to be removed from the component mounting line L3 after the production of the lot X4 is completed, but the preparatory work number is due to the delay in the production work of the lot X4. The preparatory work for Y8 cannot be started.

Therefore, the production of the lot X8, which is carried out by attaching the bogie group Z4 after the preparatory work of the preparatory work number Y8 to the component mounting line L1, cannot be started. Therefore, the progress management unit 12 determines that the plan needs to be revised based on the progress difference of the component mounting line L3, and the instruction change unit 14 issues a change instruction to the production planning device 6. The correction plan planning unit 22 changes the preparation work, for example, from the dolly group Z4 to the dolly group Z2 or the dolly group Z3 stored in the preparation area As. Create (plan) a modified production plan 23k to accompany it.

Next, with reference to FIG. 9, another embodiment of the component mounting system 1 (progress management system) will be described. FIG. 9 is an explanatory diagram of another example of the data structure used in the component mounting system 1 (progress management system) of another embodiment of the present disclosure. In another embodiment, the production planning device 6 associates the order number with the production plan 23g and the preparation plan 23h and transmits them to the line management devices B1 to B3 and the preparation work management device 7 (progress). It is different from the management system). That is, the planning unit 21 of the production planning apparatus 6 associates the created production plan 23g and the preparation plan 23h with the order number included in the order information 23a and stores them in the planning storage unit 23.

The planning communication unit 20 of the production planning device 6 transmits the production plan 23g associated with the order number to the line management devices B1 to B3, and transmits the preparation plan 23h associated with the order number to the preparation work management device 7. .. Each of the off-line communication units 30 of the line management devices B1 to B3 transmits the production instruction 34c and the production record 34d to the production control device 3 in association with the order number included in the production plan 23g. The preparation communication unit 40 of the preparation work management device 7 associates the preparation instruction 43c and the preparation record 43d with the order number included in the preparation plan 23h and transmits the order number to the production control device 3.

The data structure including the preparation record information 15e, which is the preparation record 43d, is based on the production instruction information 15b, the preparation instruction information 15c, the production record information 15d, and the preparation record information 15e by the progress management system (parts mounting system 1). , Used in the process of identifying the work production progress and managing the work production progress. As a result, the progress status of the entire production floor F can be easily grasped.

Although omitted in the above description for the sake of brevity, the placement work support device 4 may integrate the preparation instructions 43c for a plurality of works and instruct the worker W. For example, it may be more efficient to perform preparatory work in parallel for a plurality of works whose production start times are close to each other. In this case, if an order number is associated with each of the preparatory work performed by the worker W, it is possible to manage which work is smooth or delayed among the preparatory work of each of the plurality of works. be able to.

Further, also in the line management devices B1 to B3, the production instructions 34c for a plurality of workpieces may be integrated and instructed to the component mounting lines L1 to L3. For example, the component mounting devices M3 to M6 are provided with two lanes for transporting the workpieces in parallel, and the production work may be performed in parallel on the workpieces of different types in the respective lanes. In such a case, if the order number is associated with the production instruction 34c given to each work by the component mounting devices M3 to M6, which of the plurality of works is in good condition is delayed. You can manage if you are there.

Although the placement work was explained as the preparatory work, the following work may be included in the preparatory work in addition to the placement work. That is, the work of removing the screen mask from the storage shelf, the work of removing the solder adhering to the screen mask after use, the work of removing the parts necessary for production from the storage shelf, and the remaining number of parts used for production. For counting work, returning used parts used for production to storage shelves (including automatic warehouses and humidity control warehouses), moving the trolley 5 used for production to a specific position in the preparation area As, and production. The work of returning the used trolley 5 to the preparation area As and moving it to the storage position for storage until the next use, the work of preparing the suction nozzle used for production, and the work of storing the suction nozzle used in production in the storage shelf (nozzle storage).

The work of collecting the solder for use in the next production may be included.

In addition, these works can be divided into pre-preparation work performed before production and post-preparation work performed after production depending on the dependency before and after production. Placement work is an example of work that has pre-production dependencies. One of the operations that has a dependency after production is the operation of removing the solder adhering to the screen mask after use. In addition, for work that has or does not have a dependency relationship both before and after production, pre-preparation work and post-preparation work are set according to the part type to be produced, the production floor F, and the worker W, and the pre-preparation work and the post-preparation work are set.

Instead of using the dolly 5, the transport vehicle V may transport the magazine that stores the members. That is, in the preparation area As, the preparatory work for preparing the members in the magazine instead of the carriage 5 may be performed.

In the above, the management of the production progress of the mounting board has been described by taking the component mounting lines L1 to L3 for mounting the components on the board as an example of the production line, but the management of the production progress is not limited to this. For example, the production line may be a semiconductor production line that manufactures semiconductors. Further, it may be an assembly production line for assembling electrical equipment. It may also be a food processing line that produces processed food products.

Although the term pre-preparation work was used above, pre-production work and pre-production work may be used as synonymous terms. In addition, although the term post-preparation work has been used above, post-production work and post-production work may be used as synonymous terms.
