1. Embodiment 1-1. Overview of Management System 1 The production management device manages a plurality of production lines that mount components on circuit boards to produce circuit board products, and a plurality of storages that store a plurality of types of components supplied to the production lines. . In the present embodiment, as shown in FIG. 1, the production control device 50 is connected to other production control devices 50 so as to be communicable, and cooperates to form a control system for overall control of production. The management system 1 enables a plurality of production management apparatuses 50 forming a network to use mutual information. In addition, below, a "circuit board" is simply called 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 apparatuses in the direction of substrate transport (horizontal direction in FIG. 2). Each of the plurality of production apparatuses is communicably connected to each other and to a host computer (hereinafter referred to as "host PC") in which the production management apparatus 50 is installed. A production line 10 includes a printer 11 , a plurality of component mounters 14 and a reflow oven 16 .

The printing machine 11 prints paste-like solder on the mounting positions of the components on the loaded board. Each of the plurality of component mounters 14 mounts components on the solder of the board 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 for soldering.

In this way, the production line 10 sequentially conveys the substrates to each production apparatus, executes production processing including inspection processing, and produces substrate products. 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, 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

1-3. Mounting Process by Component Mounting Machine 14 The component mounting machine 14 executes a mounting process of mounting a component 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 a control program generated in advance, information output from various sensors, and recognition processing results obtained by image processing. . A control program used for the mounting process is generated based on the production plan M1 (see FIG. 2) and product information M2.

In addition, the component mounting machine 14 manages the remaining number of a plurality of components supplied to the component mounting machine 14 so as not to run out of components in the executed mounting process. The component mounter 14 requests the host PC to replenish components when, for example, the remaining number of components of a predetermined type is below a certain level. When the operator replenishes the parts accordingly, the mounting process in the part mounting machine 14 is continued.

In addition, the supply of the above parts includes the supply of a carrier tape in which a large number of parts are accommodated at predetermined intervals, the supply of a stick in which a plurality of parts are arranged in a line in a linear main body, and the supply of a plurality of parts. Includes replacement of bulk cases that have been received in pieces. The supply of the carrier tape includes splicing for connecting the tip of the carrier tape for supply to the trailing end of the carrier tape currently in use, replacement or supply of the supply reel on which the carrier tape is wound, and the like. .

1-4. Configuration of Storage Warehouse 20 Storage warehouse 20 stores many types of parts according to the storage form of the parts. Component storage forms include reels, sticks, bulk cases, and the like, as described above. The storage 20 includes a storage shelf 21, a work table 22, a transport device 23, and a control device 24, as shown in FIG. 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 holds the reels and the like in line.

The work table 22 is temporarily placed with parts to be stored in or delivered from the stocker 20 . The transport device 23 transports components between a predetermined storage position on the storage shelf 21 and the work table 22 . The conveying device 23 grasps a reel or the like at a predetermined storage position and reads an identification code attached to the reel or the like, for example, to check whether the part is correct or not when the part is delivered. After that, the conveying device 23 places the held reel or the like on the work table 22 .

The control device 24 stores storage information indicating the storage position of each part in the storage shelf 21 together with the part information such as the identification code, the type of the part, the remaining number, the storage form, and the expiration date for the parts stored in the storage box 20 . have. The control device 24 controls the operation of the conveying device 23 and appropriately updates the part information and storage information in order to, for example, deliver parts of a predetermined type or store parts to be used later.

The stocker 20 described above has a function of automatically stocking and unloading parts as described above, and is of a type with a high level of automation. On the other hand, there are types of other storages that do not have the function of transporting parts and have a low level of automation. The type of storage with a low level of automation includes those that guide storage locations and update various information based on part information and storage information, and those that only determine the presence or absence of parts and do not have a function to recognize storage locations. and are included.

Here, the production line 10 is associated with one or a plurality of stockers 20 that store parts used for production by the production line 10 . In other words, when a plurality of production lines 10 and a plurality of storages 20 are installed in the same building, the parts scheduled to be supplied to each of the plurality of production lines 10 are mixed and stored in the plurality of storages 20. Instead, they are stored in a storehouse 20 that is associated with the production line 10 on a one-to-one or one-to-many basis. Such association is set in advance in consideration of the convenience based on the distance between the production line 10 and the stocker 20 and the manageability of the parts in the control device 24 of the stocker 20 .

Also, the stocker 20 is installed, for example, on the same floor or building as the associated production line 10 . The plurality of stockers 20 are appropriately replenished with parts from a parts warehouse (not shown) that stores a large amount of parts purchased from a parts supplier, for example. The replenishment from the parts warehouse to the stocker 20 is based on the production plan M1, the product information M2, the inventory information of the parts warehouse, etc. It is done by

1-5. Overview of Production Control Device 50 In this embodiment, the production control device 50 constitutes the control system 1 together with 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 storage warehouses 20 installed on the same floor, and a host communicatively connected thereto. Built in PC.

When any one of the production lines 10 is requested to replenish parts of a predetermined type, the production control device 50 responds to the request from the storage box 20 corresponding to the requested production line 10. Manage to issue parts. Specifically, the production control device 50 first inquires about the number of stocks of the predetermined type of parts in the corresponding stocker 20 . Next, the production control device 50 confirms that the stocker 20 is sufficiently replenished with parts and has inventory that satisfies the required number, and instructs the stocker 20 to take out the parts.

As described above, in a normal operation state, the production control device 50 confirms the inventory in the storage warehouse 20 associated with a request for parts replenishment from the production line 10 and issues a part delivery command. . However, due to reasons such as insufficient replenishment of parts in the stocker 20, the stock of the requested parts may not be available in the associated stocker 20, or the required number may not be met. Then, in the conventional production management, the operator is required to replenish the associated stocker 20 with the parts or directly replenish the requested production line 10 with the parts.

By the way, even when different types of substrate products are produced in a plurality of production lines 10, the same component type may be used for production. Then, for example, the requested parts may be stored in the storehouse 20 installed on the same floor, although they are not associated with the production line 10 that requested the parts supply.

Maintaining the relationship between the production line 10 and the storage warehouse 20 is important from the viewpoint of production management. On the other hand, under the circumstances described above, it may be more effective from the viewpoint of maintaining production efficiency to have the requested production line 10 take out the parts from the incompatible storage warehouse 20 . Therefore, the production management device 50 of the present embodiment employs the following configuration in order to coordinate the plurality of production lines 10 and the plurality of stockers 20 and guide the delivery of parts more appropriately.

1-6. Location of Production Line 10 and Storage Warehouse 20 As shown in the rightmost column of FIG. ). Each of the multiple divisions (N1, N2, N3, ...) is a country (A, B, ...), a region in the country (C1, C2, C3, ...), a facility established in the region (PL1, PL2, PL3, . . . ), buildings (B11, B12, B13, . , D12, D13, . . . ).

For example, the first section N1 in which the production line 10 having the identification code (La11) is installed includes the first country A, the region C1, the facility PL1, the building B11, the floor F1, It is indicated by six location compartments such as the installation area D11. Here, the "facility" provided in the area includes a factory, a manufacturing site, etc., and is composed of one or more buildings. The above section is an arbitrary set value. For example, when the "facility" consists of one building, either the facility or the building may be included as the location section.

The production control device 50 quantifies the location of the production line 10 and the stocker 20 by setting the division information M3 as described above for each country, for example. This makes it possible to evaluate the commonality of the location classifications of the production line 10 and the stocker 20 . Also, by setting the relationship of each element in each location category, for example, by setting the distance between each element of "building" (B11, B12, B13, ...) as the relationship, The distance between the installed production line 10 and the stocker 20 can be calculated.

In the following, the most extensive category (“Country (A, B, . . . )” in the above example) among the plurality of location categories is the highest location category. Also, the plurality of location divisions become narrower from left to right in FIG. The installation area (D11, D12, D13, . . . ) among the plurality of location segments is the narrowest segment and is positioned at the lowest position segment.

In addition, the thick frame in FIG. 3 indicates the combination of the production line 10 and the stocker 20 that are associated with each other. For example, on the floor F1 of the building B11 of the facility PL1, there is a storage 20 (Sa13) associated with two production lines 10 (La11, La12) and a storage facility associated with one production line 10 (La14). A warehouse 20 (Sa15) is installed. Under normal operating conditions, supply of parts to the production line 10 and storage of parts left over from production processing by the production line 10 are carried out between the production line 10 and the storage box 20 surrounded by a thick frame in FIG. Completed by exchanging parts at

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

By recognizing the progress of production processing in the production line 10 , the production management device 50 can grasp the remaining number of parts supplied to the plurality of component mounting machines 14 in the production line 10 . Furthermore, the production management device 50 can estimate when parts will run out based on the type of product to be produced and the number of parts required for the type of product. Therefore, in addition to the component mounter 14 of the production line 10 sending a request for parts supply to the host PC as described above, there are cases where the production control device 50 incorporated in the host PC issues a request for parts supply as necessary. be.

The retrieval unit 52 receives a request to supply a predetermined type of parts to any one of a plurality of production lines 10, and retrieves the inventory of the requested parts in the stocker 20 corresponding to the production line 10 that has made the request. is not sufficient, search one or more stockrooms 20 from which the requested parts can be shipped. In other words, if there is a shortage of parts inventory in the storage warehouse 20 associated with the production line 10 that requested the parts supply, the search unit 52 searches for, for example, the non-corresponding storage warehouse 20 installed on the same floor. An attempt is made to detect a storage warehouse 20 from which parts can be delivered according to the request, among the non-compliant storage warehouses 20 installed in other buildings.

Here, all the stockers 20 that constitute the management system 1 and are communicably connected to the production management device 50 can be searched by the search unit 52 . In this embodiment, when searching for the storage warehouse 20 from which the requested parts can be delivered, the search unit 52 searches for a plurality of location categories that indicate the section in which the requested production line 10 is installed, and a common location category. A search is made for the storage warehouses 20 from which the requested parts can be delivered in order from one or a plurality of storage warehouses 20 having the largest number of parts. As a result, it is possible to reduce the processing load such as the search processing by the search unit 52 .

Here, the parts supplied from the stocker 20 to the production line 10 are removed from the feeder or the like and returned to the stocker 20 again if they remain after being used in the production process. In this way, the remaining parts used in the production process that has already been completed on the production line 10 or the remaining parts used in the production process that is scheduled to be completed at a certain time are currently supplied to the production line 10. Although there is, it is likely to be stored in the storage warehouse 20 associated with the production line 10 .

In addition, the production management device 50 can recognize the degree of progress of production processing in the production line 10, etc., as described above. Using this, the search unit 52, when searching for the stocker 20 from which the requested parts can be delivered, retrieves a plurality of parts used in production processes that have finished or are scheduled to finish on a plurality of production lines 10. Remaining parts supplied to the production line 10 are regarded as parts stored in a plurality of stockers 20 respectively corresponding to a plurality of production lines 10, and are included in search targets.

The above-mentioned "supplied state" in the production line 10 means a state in which components are loaded in a feeder or the like and set in the component supply device of the component mounting machine 14, or a state in which the above-mentioned feeder or the like is set in the component supply device. This includes a state in which the components are loaded on a delivery trolley, and a state in which a plurality of feeders, etc. are set on a device pallet that holds the feeders, etc. so that they can be set on the component supply device all at once. By regarding such residual parts as parts in a preliminary storage state and making them search targets, it is possible to search for parts of a predetermined type more extensively.

The guide unit 53 guides one or more storages 20 based on the search result of the search unit 52 . Various modes are assumed for the guide processing of the repository 20 based on the search result by the guide unit 53 . Details of each aspect of the guidance process will be described later. Further, in the present embodiment, the guiding unit 53 is configured to select a storage warehouse 20 (hereinafter, also referred to as an "alternative storage warehouse 20T") from which a requested part is delivered out of the plurality of storage warehouses 20. , if the level of automation of the alternative storage 20T is high and parts can be automatically delivered, the alternative storage 20T is instructed to deliver the requested parts.

According to such a configuration, the guide unit 53 automatically sends out a delivery command to the alternative storage 20T, so that the delivery operation in the alternative storage 20T is started earlier. In addition, the operator can omit the task of sending out a delivery command to the designated storage warehouse 20, and can head to the storage warehouse 20 designated as the storage warehouse 20 from which parts can be shipped.

1-8. Processing for Responding to Request for Parts Supply The processing for responding to requests for parts supply by the production control device 50 will be described with reference to FIGS. 3 to 7. FIG. Here, it is assumed that each production line 10 is executing production processes for producing various board products. Further, it is assumed that the part information and the storage information are appropriately updated in each stocker 20 each time the parts are received and delivered.

When there is a request to supply parts of a predetermined type to any one of the plurality of production lines 10, the production control device 50 executes processing for responding to the parts supply request, as shown in FIG. do. A request for parts replenishment is made by the parts mounter 14 of the production line 10 or the production control device 50 that monitors the progress of the production process. Hereinafter, the production line 10 that has requested the supply of parts will be referred to as a "requested line 10R".

The production control device 50 first determines whether or not the inventory of the requested parts is sufficient in the stocker 20 associated with the request line 10R (step 10 (hereinafter, "step" is abbreviated as "S"). )). When the inventory of parts is sufficient (S10: Yes), the production control device 50 omits the search processing (S20) described later and executes the guidance processing of the stocker 20 (S30). On the other hand, if the parts inventory is not sufficient (S10: No), the search unit 52 searches for one or a plurality of storage containers 20 (hereinafter also referred to as "substitution candidates 20H") that are candidates for the replacement storage container 20T. A search process is executed to attempt detection (S20).

In the present embodiment, the search process (S20) by the search unit 52 employs a method of gradually expanding the search target until the alternative candidate 20H is detected. Specifically, as shown in FIG. 5, the search unit 52 first acquires a section in which the request line 10R is installed (S21). For example, if the required line 10R is the first production line (La11) shown in the top row of FIG. D11).

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

Subsequently, the search unit 52 searches for the replacement candidate 20H in the set search target (S23). Specifically, it is determined whether or not the requested component type 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 requested component type 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, in the stocker 20 (Sa15) installed in the search target range (floor F1), the requested part is not stored and the part cannot be taken out. Thus, 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 section (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 a search target range as a current value.

Subsequently, the search unit 52 searches again for the replacement 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 requested part type in the storage 20 (Sa22) installed in the same building B11. Determine whether or not More precisely, the storages 20 installed in the same building B11 include the storages 20 (Sa15) installed on the same floor F1 previously set as the search target range, but the search (S23 ) is excluded.

As described above, until the replacement candidate 20H is detected, the search target range is set one by one to the higher location categories (S22). Then, the search unit 52 searches for the replacement candidates 20H based on whether or not the requested part type is stored in the one or more storages 20 newly added to the search targets by the search target setting process. (S23). By repeating the above-described processing, the search unit 52 detects alternative candidates 20H in order from one or a plurality of storages 20 having many location categories in common with a plurality of location categories indicating the section in which the request line 10R is installed. try

When one or a plurality of alternative candidates 20H are detected (S24: Yes), the search unit 52 ends the search process for the alternative candidates 20H. In addition, for the parts stored in the storage warehouse 20 installed in the set search target range, the production processing that has been completed or the production that is scheduled to be completed in the one or more production lines 10 associated with the storage warehouse 20 Remaining parts that have been used for processing and have been supplied to the production line 10 are included.

Specifically, when searching for the replacement candidates 20H, the search unit 52 first acquires the progress of production processing in one or a plurality of production lines 10 installed in the range to be searched, and obtains the respective remaining parts. Dividing out. Then, the search unit 52 searches for the remaining parts assuming that they are stored in the storage box 20 (S23).

It should be noted that when determining the remaining parts, the search unit 52 may first determine whether or not the requested part type has been used for the production process in one or a plurality of production lines 10 . When determining that the requested 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 remaining part. Thereby, the search unit 52 can efficiently identify the remaining parts.

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

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

The above-mentioned "priority" is the priority of guidance set for each of a plurality of stockers 20 for the production line 10 that requested. Specifically, the priority is set to at least one of the distance between the request line 10R and each of the plurality of storages 20, the number of parts in stock or expiration dates in the storages 20, and the automation level of shipping processing in the plurality of storages 20. set based on

More specifically, for example, when the priority is set based on the distance between the request line 10R and each of the plurality of storage containers 20, the alternative candidate 20H with the shortest distance from the request line 10R is the alternative storage container 20T. is specified. 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 where 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.

Also, when the priority is set based on the number of parts in stock, the alternative candidate 20H that stores the part with the larger number of parts in stock or the part 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 replacement candidate 20H storing the one with the shorter expiration date is designated as the replacement storage 20T.

When the priority is set based on the automation level of shipping processing in a plurality of storage warehouses 20, a substitute candidate 20H with a high automation level and capable of automatically shipping parts is designated as the substitute storage warehouse 20T. . The priority of guidance may be set by taking into consideration various elements such as the distance and the number of items in stock as described above. The priority of guidance is preset by, for example, the manager of the production control device 50 and recorded in the priority information M4 (see FIG. 2).

On the other hand, if 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 section 53 guides the alternative storage box 20T designated in S312 and S313 (S314). Specifically, the guide unit 53 guides the operator by displaying on a terminal viewable by the operator that the requested parts are stored in the alternate storage 20T. Further, if there is sufficient inventory in the stocker 20 associated with the request line 10R (S10: Yes), the search processing (S20) is omitted and the substitute candidate 20H is 0 (S311 : 0), and guides the stocker 20 associated with the request line 10R (S314).

In addition, when guiding the alternative storage 20T as described above, the guiding unit 53 also provides information on 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. , and the required time for picking it up may also be provided. Further, the guidance unit 53 may also provide information such as the number of parts in stock, expiration date, appearance of parts (reel, etc.) according to the request in the alternative storage 20T in the above guidance.

After that, if the alternative storage warehouse 20T or the like can automatically take out the parts (S315: Yes), the guidance unit 53 guides the alternative storage warehouse 20T or the like (S314) as described above, The storehouse 20T or the like is instructed to take out the requested parts (S316). As a result, for example, the guide unit 53 automatically sends out a delivery command to the alternative storage 20T, so that the delivery operation in the alternative storage 20T is started earlier. In addition, the operator can omit the task of sending out a delivery command to the designated alternative storage warehouse 20T.

On the other hand, if the automation level of the alternative storage warehouse 20T or the like is low and the parts cannot be automatically shipped (S314: No), the guidance unit 53 skips sending the shipping instruction to the alternative storage warehouse 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 replacement candidates 20H that can deliver the requested part (S311: Yes), the One alternative candidate 20H is designated and guided (S312, S313). As a result, it is possible to reduce the burden on the operator and speed up the replenishment of parts.

1-8-2. Second Aspect of Guidance Processing In the second aspect of the guidance processing, as shown in FIG. 7, the guidance section 53 first determines whether or not there is a replacement candidate 20H in the result of the search processing (S20) (S321). If there is one or more alternative candidates 20H in the search processing result (S321: Yes), one or more alternative candidates 20H are guided to be selectable (S322). Specifically, the guiding unit 53 displays a list of alternative candidates 20H on a terminal that can be viewed by the operator. At this time, if the result of the search process (S20) includes a plurality of alternative candidates 20H, the guidance unit 53 displays a list according to the respective priorities. In other words, the guiding 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 their priorities.

In addition, in the list display of the plurality of substitution candidates 20H, the guiding unit 53 displays the installation position of the substitution candidate 20H, the movement route to the installation position, and the location based on the location section in which each of the plurality of substitution candidates 20H is installed. You may also provide guidance on the required time when going to Furthermore, the guidance unit 53 may also provide guidance on the number of parts in stock, the expiration date, the appearance of parts (reels, etc.), etc., for the parts requested in the replacement candidate 20H in the above list display.

Next, for example, when the operator selects the alternative candidate 20H (S323), the guiding unit 53 designates the selected alternative candidate 20H as the alternative storage 20T (S324). Note that even when there is only one alternative candidate 20H included in the result of the search process (S20), the guide unit 53 may similarly display that alternative candidate 20H (S322) and designate it as the alternative storage box 20T. A selection is accepted to confirm with the operator whether or not (S323).

Subsequently, the guide unit 53 guides the alternative storage box 20T designated in S324 (S325). Specifically, the guide unit 53 guides the operator by displaying on a terminal viewable by the operator that the requested parts are stored in the alternate storage 20T. At this time, the guiding unit 53 may also provide information such as the installation position of the alternative storage container 20T and the moving distance to the installation position as various information regarding the alternative storage container 20T. Further, if there is sufficient inventory in the stocker 20 associated with the request line 10R (S10: Yes), the search processing (S20) is omitted and the substitute candidate 20H is 0 (S321 : No), the storage 20 associated with the request line 10R is guided (S325).

After that, the guide unit 53 is set to automatically send out a delivery command when the storage 20 to which the alternative storage 20T or the like has been guided can automatically release the parts (S326: Yes). It is determined whether or not there is (S327). Whether the delivery command is sent automatically or manually is set in advance by, for example, the manager of the production control device 50 and stored in the storage unit 51 as setting information. If the setting is made to automatically send out the delivery command (S327: Yes), the guiding section 53 commands the substitute storage 20T or the like to deliver the requested parts (S328). .

On the other hand, if the automation level of the alternative storage 20T or the like is low and parts cannot be automatically shipped (S326: No), or if a setting is made to manually send a shipping command (S327: No), The guidance unit 53 omits sending out a delivery command to the alternative storage warehouse 20T or the like, and terminates the guidance processing. According to the configuration of the second aspect of the guidance process as described above, it is possible to guide the alternative candidate 20H while reflecting the priority, and allow the operator to specify the alternative storage box 20T. As a result, the operator can designate the alternative stocker 20T according to the production status and the like.

In the first mode and the second mode described above, one or more alternative candidates 20H are detected in the search results of the search process (S20). On the other hand, if the replacement candidate 20H is not detected despite the execution of the search process (S20), the guidance unit 53 provides guidance to that effect, for example. The stocker 20 is replenished with parts, or the request line 10R is guided to replenish the parts directly.

In addition, in the process of responding to the request for parts replenishment as described above, if the inventory of parts is not sufficient in the stocker 20 associated with the request line 10R (S10: No), the parts are removed from the guided alternative stocker 20T. is replenished, the parts that were scheduled to be used in the alternate storage 20T will be used for unscheduled production processing. In this case, it is predicted that parts will run short in the alternative storage 20T in the future.

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

2. Effect of the Configuration of the Embodiment According to the production management device 50 described above, when the inventory of the requested parts is not sufficient in the stocker 20 corresponding to the request line 10R requesting the supply of the parts (S10: No), other A search is made for a substitute candidate 20H for the stocker 20 associated with the production line 10 of (S20).

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

3. Modified Aspects of the Embodiments In the embodiments, the production control device 50 has been exemplified as being incorporated in the 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 that is communicably connected to a plurality of production devices and a host PC that constitute the existing production line 10 . Accordingly, the production control device 50 may be installed for each building, each facility, each region, or each country, and may be configured to integrally manage the production lines 10 and storage warehouses 20 for each of these categories.
