1. 1. Embodiment 1-1. Outline of the management system 1 The production control device manages a plurality of production lines for producing board products by mounting parts on a circuit board and a plurality of storages for storing a plurality of types of parts supplied to the production lines. .. In the present embodiment, as shown in FIG. 1, the production control device 50 is connected to another production control device 50 in a communicable manner to cooperate with each other to form a management system for overall management of production. The management system 1 makes it possible for a plurality of production control devices 50 constituting the network to use mutual information. In the following, the "circuit board" is simply referred to as a "board".

1-2. Configuration of Production Line 10 As shown in FIG. 2, the production line 10 is configured by installing a plurality of production devices in the substrate transport direction (left-right direction in FIG. 2). Each of the plurality of production devices is connected to each other so as to be able to communicate with each other and to communicate with a host computer (hereinafter, referred to as "host PC") in which the production control device 50 is incorporated. The production line 10 includes a printing machine 11, a plurality of component mounting machines 14, and a reflow furnace 16.

The printing machine 11 prints the paste-like solder at the mounting position of the component on the carried-in substrate. Each of the plurality of component mounting machines 14 mounts components on the solder of the substrate conveyed from the upstream side of the production line 10. The mounting process by the component mounting machine 14 will be described later. The reflow furnace 16 heats the substrate conveyed from the upstream side of the production line 10 to melt the solder on the substrate and perform soldering.

In this way, the production line 10 sequentially conveys the substrate to each production apparatus, executes the production process including the inspection process, and produces the substrate product. The configuration of the production line 10 can be appropriately added or changed according to, for example, the type of substrate product to be produced. For example, in the production line 10, for example, a buffer device for temporarily holding a substrate to be transported, a substrate supply device, a substrate reversing device, various inspection devices, a shield mounting device, an adhesive coating device, an ultraviolet irradiation device, etc. are appropriately installed. Can be done.

1-3. Mounting process by the component mounting machine 14 The component mounting machine 14 executes a mounting process for mounting components on a substrate as a production process. In the mounting process, the component mounting machine 14 controls the operation of the mounting head that holds the component based on the control program generated in advance, the information output from various sensors, the result of the recognition process by image processing, and the like. .. The control program used for the mounting process is generated based on the production plan M1 (see FIG. 2) and the product information M2.

Further, the component mounting machine 14 manages the remaining number of a plurality of parts supplied to the component mounting machine 14 so that the parts will not be cut off in the executed mounting process. The component mounting machine 14 requests the host PC to replenish the components when, for example, the remaining number of components of a predetermined type becomes a certain amount or less. The operator replenishes the parts in accordance with this, so that the mounting process in the parts mounting machine 14 is continued.

The above-mentioned parts can be replenished by replenishing a carrier tape in which a large number of parts are housed at predetermined intervals, replenishing a stick in which a plurality of parts are housed in a row in a linear main body, and a plurality of parts. Includes replacement of bulk cases housed in pieces. Note that the replenishment of the carrier tape includes splicing in which the tip of the replenishment carrier tape is connected to the rear end of the carrier tape currently in use, replacement or replenishment of the replenishment reel around which the carrier tape is wound, and the like. ..

1-4. Configuration of storage 20 The storage 20 stores a large number of types of parts according to the storage form of the parts. The housing form of the parts includes a reel, a stick, a bulk case, and the like as described above. As shown in FIG. 2, the storage 20 includes a storage shelf 21, a work table 22, a transport device 23, and a control device 24. The storage shelf 21 is formed according to the storage form of the parts. The storage shelf 21 is configured so that individual reels and the like can be sorted, and the reels and the like are arranged and held.

The work table 22 is temporarily placed with parts to be stored or delivered to the storage 20. The transport device 23 transports parts between a predetermined storage position on the storage shelf 21 and the work table 22. When the parts are delivered, the transport device 23 grips the reel or the like at a predetermined storage position and reads, for example, the identification code attached to the reel or the like to confirm the correctness of the parts. After that, the transport device 23 places the held reel or the like on the work table 22.

For the parts stored in the storage 20, the control device 24 provides the storage information indicating the storage position of each part on the storage shelf 21 together with the part information such as the identification code, the part type, the remaining number, the storage form, and the expiration date. Have. The control device 24 controls the operation of the transport device 23 and updates the component information and the storage information as appropriate, for example, in order to deliver a predetermined type of component or store a component scheduled to be used later.

The storage 20 is a type with a high level of automation, which has a function of automatically warehousing and unloading parts as described above. On the other hand, other storages do not have a function of transporting parts and have a low level of automation. The type of storage with a low level of automation is one that guides the storage position and updates various information based on the parts information and storage information, and one that does not have the function of recognizing the storage position only by determining the presence or absence of parts. And are included.

Here, the production line 10 is associated with one or more storage units 20 for storing parts used for production by the production line 10. That is, when a plurality of production lines 10 and a plurality of storages 20 are both installed in the same building, the parts to be supplied to each of the plurality of production lines 10 are mixedly stored in the plurality of storages 20. Instead, it is stored in the storage 20 which is associated with the production line 10 on a one-to-one or one-to-many basis. Such an association is preset in consideration of convenience based on the distance between the production line 10 and the storage 20 and the manageability of parts in the control device 24 of the storage 20.

Further, the storage 20 is installed on the same floor or building as the associated production line 10, for example. Parts are appropriately replenished in the plurality of storages 20 from, for example, a parts warehouse (not shown) that stores a large amount of parts purchased from a parts supplier. For replenishment from the parts warehouse to the storage 20, the replenishment time and the type of parts to be replenished are specified based on the production plan M1, product information M2, inventory information of the parts warehouse, etc., and the operator stores the parts in the storage 20. It is done by doing.

1-5. Outline of the production control device 50 In the present embodiment, the production control device 50 constitutes the management system 1 together with the other production control devices 50 as described above. More specifically, as shown in FIG. 2, the production control device 50 manages a plurality of production lines 10 and a plurality of storages 20 installed on the same floor, and is a host communicably connected to these. It is built into the PC.

When any one of the plurality of production lines 10 is requested to be replenished with parts of a predetermined type, the production control device 50 responds to the request from the storage 20 corresponding to the requested production line 10. Manage parts to be shipped. Specifically, the production control device 50 first inquires about the number of parts in stock of a predetermined type in the corresponding storage 20. Next, the production control device 50 confirms that the storage 20 is sufficiently replenished with parts and has an inventory satisfying the required number, and instructs the storage 20 to deliver the parts.

As described above, in the normal operation state, the production control device 50 confirms the inventory in the associated storage 20 and issues a parts delivery command in response to the request for parts supply by the production line 10. .. However, due to reasons such as the storage 20 not being sufficiently replenished with parts, the associated storage 20 may not have the required parts in stock or may not meet the required number. Then, in the conventional production control, the operator is required to replenish the parts in the associated storage 20 or directly replenish the parts in the requested production line 10.

By the way, even when different types of substrate products are produced on a plurality of production lines 10, the parts types used for the production may be common. Then, for example, although it is not associated with the production line 10 that has requested the supply of parts, the parts corresponding to the request may be stored in the storage 20 installed on the same floor.

Maintaining the relationship between the production line 10 and the storage 20 associated with the production line 10 is important from the viewpoint of production control. On the other hand, under the above circumstances, it may be more effective to have the parts delivered from the non-compliant storage 20 to the requested production line 10 from the viewpoint of maintaining production efficiency. Therefore, the production control device 50 of the present embodiment adopts the following configuration in order to more appropriately guide the delivery of parts by linking the plurality of production lines 10 and the plurality of storages 20.

1-6. Locations of Production Line 10 and Storage 20 As shown in the rightmost column of FIG. 3, each of the plurality of production lines 10 and the storage 20 is different from each other (N1, N2, N3, ... ) Is installed. Each of the plurality of sections (N1, N2, N3, ...) Is a country (A, B, ...), a region in the country (C1, C2, C3, ...), A facility provided in the region. (PL1, PL2, PL3, ...), the buildings that make up the facility (B11, B12, B13, ...), the floors in the building (F1, F2, ...), and the installation area on the floor (D11). , D12, D13, ...) By at least three or more location categories.

For example, the first section N1 in which the production line 10 having the identification code (La11) is installed has the first country A, the area C1, the facility PL1, the building B11, the floor F1, as shown in the uppermost part of FIG. It is indicated by six locations such as the installation area D11. Here, the "facility" provided in the area includes a factory, a factory, etc., and is composed of one or more buildings. The above-mentioned section is an arbitrary setting value, and for example, when the "facility" is composed of one building, one of the facility or the building may be included as the location classification.

The production control device 50 quantifies the locations of the production line 10 and the storage 20 by setting the above-mentioned division information M3 for each country, for example. This makes it possible to evaluate the commonality of the location classifications of the production line 10 and the storage 20. Further, by setting the relationship of each element in each location classification, for example, by setting the distance between each element (B11, B12, B13, ...) Of the "building" as a relationship, these can be set. It is possible to determine the distance between the installed production line 10 and the storage 20.

In the following, the broadest category among the plurality of location categories (“country (A, B, ...)” In the above example) will be the highest level of the location category. Further, the plurality of location divisions become narrower from the left to the right in FIG. The installation area (D11, D12, D13, ...) Of the plurality of location divisions is the narrowest division and is located at the lowest position of the location division.

The thick frame in FIG. 3 shows the combination of the associated production line 10 and the storage 20. For example, on the floor F1 of the building B11 of the facility PL1, the storage 20 (Sa13) associated with the two production lines 10 (La11, La12) and the storage associated with the one production line 10 (La14) are stored. A warehouse 20 (Sa15) is installed. Under normal operating conditions, the supply of parts to the production line 10 and the storage of the parts left over from the production process by the production line 10 are between the production line 10 surrounded by the thick frame in FIG. 3 and the storage 20. It is completed by exchanging parts in.

1-7. Configuration of Production Control Device 50 As shown in FIG. 2, the production control device 50 includes a storage unit 51, a search unit 52, and a guide unit 53. The storage unit 51 is composed of a hard disk, a flash memory, or the like. Setting data such as production plan M1, product information M2, and partition information M3 (see FIG. 3) is stored in the storage unit 51. The production plan M1 is information indicating the target production number for each product type to be produced. The product information M2 is information in which the component type and the number of components required for the production of the substrate product are recorded for each product type.

The production control device 50 can grasp the remaining number of replenished parts of the plurality of component mounting machines 14 of the production line 10 by recognizing the progress of the production process in the production line 10. Further, the production control device 50 can estimate the time when the parts are cut off based on the product type to be produced and the number of parts required for the product type. Therefore, the request for parts supply may be made to the host PC by the parts mounting machine 14 of the production line 10 as described above, or may be made as necessary by the production control device 50 incorporated in the host PC. is there.

The search unit 52 is requested to supply parts of a predetermined type to any one of the plurality of production lines 10, and the inventory of the parts corresponding to the request is in the storage 20 corresponding to the requested production line 10. If is not sufficient, search for one or more vaults 20 capable of delivering the requested parts. That is, when the inventory of parts is insufficient in the storage 20 associated with the production line 10 that has requested the supply of parts, the search unit 52 may use, for example, a non-compliant storage 20 installed on the same floor. Among the non-compliant storage 20 installed in another building, an attempt is made to detect a storage 20 capable of delivering parts according to a request.

Here, all the storage units 20 that constitute the management system 1 and are communicably connected to the production control device 50 can be searched by the search unit 52. In the present embodiment, when the search unit 52 searches for the storage 20 capable of delivering the parts according to the request, the search unit 52 has a common location classification as a plurality of location classifications indicating a section in which the requested production line 10 is installed. Search is performed for the storage 20 capable of delivering the parts according to the request in order from one or a plurality of storages 20 having the largest number. As a result, it is possible to reduce the processing load of the search process and the like by the search unit 52.

Here, the parts supplied from the storage 20 to the production line 10 are removed from the feeder or the like and returned to the storage 20 again when they are left over after being used for the production process. In this way, the residual parts used in the production process that has already been completed in the production line 10 or the residual parts used in the production process that is scheduled to be completed at a certain time are now in a state of being replenished in the production line 10. However, it is expected to be stored in the storage 20 associated with the production line 10.

Further, as described above, the production control device 50 can recognize the progress of the production process on the production line 10. Utilizing this, the search unit 52 is used for a plurality of production processes that have been completed or are scheduled to be completed in a plurality of production lines 10 when searching for a storage 20 that can deliver parts in response to a request. The residual parts supplied to the production line 10 are regarded as parts stored in the plurality of storages 20 corresponding to each of the plurality of production lines 10 and included in the search target.

In the "replenished state" of the production line 10, the parts are loaded in the feeder or the like and set in the parts supply device of the parts mounting machine 14, and the feeder or the like is set in the parts supply device. Therefore, the state of being loaded on the delivery carriage and the state of being set on the device pallet holding the feeders and the like so that a plurality of feeders and the like can be set at the same time on the parts supply device are included. By regarding such a residual part as a part in a preliminary storage state and targeting the search, it is possible to search for a predetermined type of part more broadly.

The guide unit 53 guides one or more storage units 20 based on the result of the search by the search unit 52. Various modes are assumed for the guidance processing of the storage 20 based on the search result by the guidance unit 53. Details of each aspect of the guidance process will be described later. Further, in the present embodiment, the guide unit 53 is a case where the storage 20 (hereinafter, also referred to as “alternative storage 20T”) for delivering the parts corresponding to the request from the plurality of storage 20 is designated. If the automation level of the alternative storage 20T is high and parts can be automatically delivered, the alternative storage 20T is instructed to deliver the parts as requested.

According to such a configuration, since the guidance unit 53 automatically sends a delivery command to the alternative storage 20T, the start time of the delivery operation in the alternative storage 20T is accelerated. Further, the operator can omit the work of sending the delivery command to the designated storage 20, and can go to the storage 20 designated as the storage 20 capable of delivering the parts.

1-8. Processing for Responding to Requests for Parts Replenishment Processing for responding to requests for parts replenishment by the production control device 50 will be described with reference to FIGS. 3 to 7. Here, it is assumed that each production line 10 is executing a production process for producing various substrate products. Further, it is assumed that the parts information and the storage information are appropriately updated in each storage 20 each time the parts are received and delivered.

When any one of the plurality of production lines 10 is requested to supply parts of a predetermined type, the production control device 50 executes a process of responding to the request for parts supply as shown in FIG. To do. The request for parts supply is made by the parts mounting machine 14 of the production line 10 or the production control device 50 that monitors the progress of the production process. In the following, the production line 10 for which parts supply is requested will be referred to as “request line 10R”.

The production control device 50 first determines whether or not the inventory of the parts corresponding to the request is sufficient in the storage 20 associated with the request line 10R (step 10 (hereinafter, "step" is referred to as "S"). It is written as)). When the inventory of the parts is sufficient (S10: Yes), the production control device 50 omits the search process (S20) described later and executes the guidance process of the storage 20 (S30). On the other hand, when the inventory of parts is insufficient (S10: No), the search unit 52 uses one or a plurality of storage units 20 (hereinafter, also referred to as “alternative candidate 20H”) as candidates for the alternative storage 20T. A search process for attempting detection is executed (S20).

In the search process (S20) by the search unit 52, in the present embodiment, a method of gradually expanding the search target until the alternative candidate 20H is detected is adopted. Specifically, as shown in FIG. 5, the search unit 52 first acquires the section in which the request line 10R is installed (S21). For example, when the request line 10R is the first production line (La11) shown in the uppermost stage of FIG. 3, the section N1 of the request line 10R has a plurality of location divisions (A, C1, PL1, B11, F1, F1,). It is shown by D11).

Next, the search unit 52 executes the search target setting process (S22). Specifically, the search unit 52 sets the variable K indicating the range of the search target to the location classification (floor F1) one higher than the lowest (installation area D11) of the section N1 of the request line 10R as an initial value. Substitute. As a result, the variable K indicates the floor F1 as the current value as the search target range.

Subsequently, the search unit 52 searches for the alternative candidate 20H in the set search target (S23). Specifically, it is determined whether or not the parts type corresponding to the request is stored in the storage 20 installed in the search target range (floor F1) indicated by the variable K. That is, since the variable K indicates the floor F1 as the search target range, it is determined whether or not the parts type corresponding to the request is stored in the storage 20 (Sa15) installed on the same floor F1. ..

The search unit 52 determines whether or not one or more alternative candidates 20H have been detected (S24). For example, the parts corresponding to the request are not stored in the storage 20 (Sa15) installed in the above search target range (floor F1), and the parts cannot be delivered. As described above, when the alternative candidate 20H is not detected (S24: No), the search unit 52 executes the search target setting process again (S22). Specifically, the search unit 52 substitutes the location category (building B11) one level higher than the current value (floor F1) in the section N1 of the request line 10R. As a result, the variable K indicates the building B11 as the current value as the search target range.

Subsequently, the search unit 52 searches again for the alternative candidate 20H in the set search target (S23). Specifically, since the variable K indicates the building B11 as the search target range, the search unit 52 stores the parts types according to the request in the storage 20 (Sa22) installed in the same building B11. Determine if it has been done. To be precise, the storage 20 installed in the same building B11 includes the storage 20 (Sa15) installed in the same floor F1 which was previously searched, but has already been searched (S23). ) Is executed, the storage 20 is excluded.

As described above, the range of the search target is set to the higher location category one by one until the alternative candidate 20H is detected (S22). Then, the search unit 52 determines the alternative candidate 20H based on whether or not the parts type corresponding to the request is stored in one or more storage units 20 newly added to the search target by the search target setting process. Is searched (S23). By repeating the above processing, the search unit 52 detects alternative candidate 20H in order from one or more storage units 20 having many location categories in common with the plurality of location categories indicating the section in which the request line 10R is installed. Try.

When one or more alternative candidates 20H are detected (S24: Yes), the search unit 52 ends the search process for the alternative candidates 20H. For the parts stored in the storage 20 installed in the set search target range, the production processing or the production scheduled to be completed in the one or more production lines 10 associated with the storage 20 Includes residual parts that have been used for processing and have been replenished to the production line 10.

Specifically, when searching for the alternative candidate 20H, the search unit 52 first acquires the progress of production processing in one or a plurality of production lines 10 installed in the search target range, and each residual component. To find out. Then, the search unit 52 searches as if the residual parts are stored in the storage 20 (S23).

In addition, when determining the residual parts, the search unit 52 may first determine whether or not the parts type corresponding to the request is used in the production process in one or a plurality of production lines 10. When the search unit 52 determines that the required part type has been used in the production process, the search unit 52 may determine whether or not the part of that type corresponds to the residual part. As a result, the search unit 52 can efficiently determine the residual parts.

As shown in FIG. 4, after the search process (S20) for the alternative candidate 20H is executed as described above, the guide process by the guide unit 53 is executed (S30). The guide unit 53 guides one or more storage units 20 (alternative candidate 20H) based on the result of the search by the search unit 52. Here, the guide unit 53 may apply a plurality of types of modes as the guide process. Here, two types of guidance processing will be illustrated.

1-8-1. First Aspect of Guidance Process In the first aspect of the guidance process, the guide unit 53 first determines the number of alternative candidates 20H in the result of the search process (S20), as shown in FIG. 6 (S311). When the number of alternative candidates 20H in the result of the search process is plural (S311: plural), the guide unit 53 designates the alternative candidate 20H having the highest priority as the alternative storage 20T (S312).

The above-mentioned "priority" is a guidance priority set for each of the plurality of storages 20 for the requested production line 10. Specifically, the priority should be at least one of the distance between the request line 10R and the plurality of vaults 20, the number of parts in stock or the expiration date in the vault 20, and the automation level of the shipping process in the plurality of vaults 20. Set based on.

More specifically, for example, when the priority is set based on the distance between the request line 10R and the plurality of storages 20, the alternative storage 20H having the shortest distance from the request line 10R is the alternative storage 20T. Is specified in. For example, when a plurality of storages 20 (Sb12, Sc12) installed in different buildings (B12, B13) of the same facility (PL1) are alternative candidates 20H, the building in which the request line 10R is installed. The storage 20 (Sb12) installed in the building (B12) closer to (B11) is designated as the alternative storage 20T.

When the priority is set based on the number of parts in stock, the alternative candidate 20H for storing the one with the larger number of stocks or the one closer to the required number of parts is designated as the alternative storage 20T. When the priority is set based on the expiration date of the part, the alternative candidate 20H for storing the one with the closest expiration date is designated as the alternative storage 20T.

When the priority is set based on the automation level of the shipping process in the plurality of storages 20, the alternative storage 20H, which has a high automation level and can automatically issue parts, is designated as the alternative storage 20T. .. The priority of guidance may be set in consideration of each factor such as the distance and the number of stocks as described above. The priority of the guidance is set in advance by, for example, the manager of the production control device 50, and is recorded in the priority information M4 (see FIG. 2).

On the other hand, when the number of alternative candidates 20H in the result of the search process (S20) is 1 (S311: 1), this alternative candidate 20H is designated as the alternative storage 20T (S313). Subsequently, the guide unit 53 guides the alternative storage 20T designated in S312 and S313 (S314). Specifically, the guide unit 53 guides by displaying on a terminal that can be viewed by the operator that the parts corresponding to the request are stored in the alternative storage 20T. Further, when the storage 20 associated with the request line 10R has sufficient inventory (S10: Yes), the search process (S20) is omitted, and the alternative candidate 20H is 0, the guide unit 53 (S311). : 0), the storage 20 associated with the request line 10R is guided (S314).

Further, when the guide unit 53 guides the alternative storage 20T as described above, the guide unit 53 sets the installation position of the alternative storage 20T and the movement route to the installation position based on the location classification in which the alternative storage 20T is installed. , You may also guide the time required when you go to pick it up. Further, in the above guidance, the guide unit 53 may guide the number of parts in stock, the expiration date, the appearance of the parts (reel, etc.), etc., according to the request in the alternative storage 20T.

After that, when the alternative storage 20T or the like can automatically issue the parts (S315: Yes), the guide unit 53 is added to the guidance (S314) of the alternative storage 20T or the like as described above, and substitutes. Instruct the storage 20T and the like to deliver the parts according to the request (S316). As a result, for example, the guide unit 53 automatically sends a delivery command to the alternative storage 20T, so that the start time of the delivery operation in the alternative storage 20T is accelerated. Further, the operator can omit the work of sending the delivery command to the designated alternative storage 20T.

On the other hand, when the automation level of the alternative storage 20T or the like is low and parts cannot be automatically delivered (S314: No), the guide unit 53 omits sending a delivery command to the alternative storage 20T or the like and performs guidance processing. finish. According to the configuration of the first aspect of the guidance process as described above, even if there are a plurality of alternative candidates 20H capable of delivering the parts according to the request (S311: Yes), the parts are automatically set according to the preset priority. One alternative candidate 20H is designated and guided (S312, S313). As a result, the load on the operator can be reduced and the replenishment of parts can be speeded up.

1-8-2. Second Aspect of Guidance Process In the second aspect of the guidance process, as shown in FIG. 7, the guide unit 53 first determines whether or not there is an alternative candidate 20H in the result of the search process (S20) (S321). When there is one or more alternative candidates 20H in the result of the search process (S321: Yes), one or a plurality of alternative candidates 20H can be selected and guided (S322). Specifically, the guide unit 53 displays a list of alternative candidates 20H on a terminal that can be viewed by the operator. At this time, when the result of the search process (S20) includes a plurality of alternative candidates 20H, the guide unit 53 displays a list according to the priority of each. That is, the guide unit 53 rearranges and displays the plurality of alternative candidates 20H in descending order of priority, or displays the plurality of alternative candidates 20H together with the priority.

Further, in the list display of the plurality of alternative candidate 20Hs, the guide unit 53 sets the installation position of the alternative candidate 20H, the movement route to the installation position, and the picking based on the location classification in which each of the plurality of alternative candidates 20H is installed. You may also guide the time required when you go to. Further, the guide unit 53 may guide the number of parts in stock, the expiration date, the appearance of the parts (reel, etc.), etc. according to the request in the alternative candidate 20H in the above list display.

Next, when the guide unit 53 accepts, for example, the operator's selection of the alternative candidate 20H (S323), the guide unit 53 designates the selected alternative candidate 20H as the alternative storage 20T (S324). In addition, when there is only one alternative candidate 20H included in the result of the search process (S20), the guide unit 53 may display the alternative candidate 20H (S322) and designate it as the alternative storage 20T. The selection is accepted so as to confirm with the operator whether or not (S323).

Subsequently, the guide unit 53 guides the alternative storage 20T designated in S324 (S325). Specifically, the guide unit 53 guides by displaying on a terminal that can be viewed by the operator that the parts corresponding to the request are stored in the alternative storage 20T. At this time, the guide unit 53 may also guide the installation position of the alternative storage 20T, the moving distance to the installation position, and the like as various information regarding the alternative storage 20T. Further, when the storage 20 associated with the request line 10R has sufficient inventory (S10: Yes), the search process (S20) is omitted, and the alternative candidate 20H is 0, the guide unit 53 (S321). : No), guide the storage 20 associated with the request line 10R (S325).

After that, the guide unit 53 is set to automatically send a delivery command when the storage 20 that has provided guidance such as the alternative storage 20T can automatically deliver the parts (S326: Yes). Whether or not it is determined (S327). Whether to send the delivery command automatically or manually is set in advance by the manager of the production control device 50, and is stored in the storage unit 51 as setting information. When the delivery command is set to be automatically sent (S327: Yes), the guide unit 53 instructs the alternative storage 20T or the like to issue the parts in response to the request (S328). ..

On the other hand, when the automation level of the alternative storage 20T or the like is low and parts cannot be automatically delivered (S326: No), or when the delivery command is set to be sent manually (S327: No), The guide unit 53 omits sending a delivery command to the alternative storage 20T or the like, and ends the guidance process. According to the configuration of the second aspect of the guidance process as described above, the operator can specify the alternative storage 20T while guiding the alternative candidate 20H reflecting the priority. As a result, the alternative storage 20T can be designated according to the production status or the like at the discretion of the operator.

In the first and second aspects described above, it is assumed that one or more alternative candidates 20H are detected in the search result of the search process (S20). On the other hand, when the alternative candidate 20H is not detected even though the search process (S20) is executed, the guide unit 53 provides guidance to that effect and is associated with the request line 10R. Instruct the storage 20 to replenish the parts or the request line 10R to replenish the parts directly.

Further, in the process of responding to the request for parts supply as described above, the inventory of parts is insufficient in the storage 20 associated with the request line 10R (S10: No), and the parts are sent from the guided alternative storage 20T. Will be used for unscheduled production processing of the parts that were planned to be used in the alternative storage 20T. Then, it is predicted that there will be a shortage of parts in the alternative storage 20T in the future.

Therefore, when parts are replenished using the alternative storage 20T, the production control device 50 records, for example, that fact and replenishes the parts delivered to the alternative storage 20T from the parts warehouse at an appropriate timing. You may be guided to do so. As a result, the storage state of the alternative storage 20T can be suitably restored while preventing the production from being stopped due to the shortage of parts.

2. 2. Effect of the configuration of the embodiment According to the above-mentioned production control device 50, when the inventory of the parts according to the request is not sufficient in the storage 20 corresponding to the request line 10R requesting the supply of parts (S10: No), etc. The alternative candidate 20H is searched for the storage 20 associated with the production line 10 of the above (S20).

As a result, one of the detected alternative candidates 20H can be designated as the alternative storage 20T, and the parts requested from the alternative storage 20T can be delivered and replenished. In this way, the production control device 50 can manage the inventory of parts as a whole by linking the plurality of production lines 10 and the plurality of storages 20. Therefore, the production control device 50 can more appropriately guide the delivery of parts.

3. 3. Modifications of the Embodiment In the embodiment, the production control device 50 illustrates an embodiment incorporated in a host PC provided for each floor. On the other hand, the production control device 50 may be an external device of the host PC. For example, the production control device 50 may be configured as a dedicated device communicably connected to a plurality of production devices and host PCs constituting the existing production line 10. As a result, the production control device 50 may be installed for each building, each facility, each region, or each country, and the production line 10 and the storage 20 may be centrally managed for each of these categories.
