[Industrial applications]

The present invention, when changing the parts used in product manufacturing,
The present invention relates to a parts management system capable of automatically performing a change process from a design parts list management subsystem and a production management subsystem.

When manufacturing a certain product in the manufacturing industry,
It is common practice to design the product in the design department and to manufacture the designed product in the production department. However, general characteristics or functions that must be possessed for each part used for a product designed by the design department are specified, but the procurement of the parts is performed by the production department on its own responsibility. It is a target. Further, in some cases, a design change for a product once designed sometimes occurs.
In parts procurement and design changes as described above, the parts used for the designed product may be different between the design department and the production department. this is,
In addition to causing parts arrangement mistakes in the production department, prolonging the double inventory period of the same function and different specifications, causing differences in the performance and quality of manufactured products, unexpected troubles with suppliers This can cause

[Conventional technology]

Conventionally, means for managing parts used for the designed product is built in a computer system. The conventional parts management system constructed in the computer system includes a design parts list management subsystem 60 and a production management subsystem 80 as shown in FIG. In this parts management system, each part used in the product to be manufactured designed in the design parts table management subsystem 60 is stored in one storage area of the disk device 24 shown in FIG. Stored as Table 62. The storage design parts table 62 is provided for each design unit or device. As the structure data, each name data found in the design parts table print example shown in FIG. 7, for example, the figure number 100, first edition design date 102, revision / date 104,
Item 106, selection code 108, number 110, part symbol level 112,
There are a product name 114, an article number 116, a standard number / remarks 118, and the like. The number of revisions in the above-mentioned revision / date 104 column indicates the largest number of revisions for the design parts list, and the standard number and remarks 118
The numerical value on the right side of the column indicates the version number at the time of revision of the relevant section. Then, the stored design parts table 62 is copied to another storage area in the disk device 24 as a design parts table 63 for temporary use via the design parts table transmission processing unit 64, and the design part table for temporary use is copied. The entire system is constructed such that only the parts list 63 can be accessed from the production management subsystem 80. Therefore, the conventional design BOM management subsystem 60
And the production management subsystem 80 operate independently of each other. 66 is a new design processing unit for designing a new product, 68 is a revised design processing unit for performing a design change process on an already-designed product, and 70 is a batch change processing unit for performing a batch change process of a design change target component. , 82 is a design parts table fetch processing unit, 84 is a production arrangement processing unit, 86 is a production arrangement master, 88 is a parts master, and 90 is an inventory management master.

[Problems to be solved by the invention]

As described above, the conventional parts management system includes a design parts list management subsystem 60 and a production management subsystem 80.
Is to operate independently of each other, so if you want to change the parts used in the product to be manufactured in one of the subsystems, you must write a document stating that fact to the subsystem In this method, the change is transmitted from the change originating subsystem to the change receiving subsystem, and information on the parts managed in the change receiving subsystem is provided. Since it takes time to update the data, a difference may occur between the information on the components managed in the change-transmitting subsystem and the information on the components managed in the change-receiving subsystem. You win.

Therefore, the above-described conventional parts management system still has the problem caused by the difference in the used parts between the two departments as described above.

The present invention has been created in view of such problems,
It is an object of the present invention to provide a component management system capable of performing automatic matching processing of a component managed by a design department and a component managed by a production department.

The step S36 in FIG. 3 of the collective change processing unit 40 and the computer system part in FIG. 5 for executing the processing correspond to the component automatic updating means 19 in FIG.

The processing of the present invention configured as described above will be described below.

The basic parts of the new design process, the revised design process, and the batch change process in the component management system of the present invention are the same as those in the related art as described above. Therefore, the writing and the change made to the design parts table 32 by those processes are performed according to the conventional method.

In the registration of the used parts in the design parts table 32 by the new design processing unit 36 (see S1 in FIG. 3), when the part to be used (see S2 in FIG. 3) specifies the old part ( (See Y in S3 in FIG. 3), and displays a message indicating that the use of the old parts is stopped on the screen of the display device 23 of the workstation 21 constituting the design BOM management subsystem 30 (see S4 in FIG. 3). To use new parts.

As described above, in the design of a certain product,
At an arbitrary time after the creation of the component 32, the component replacement instruction processing unit 35 or 52 is started, the old component and the new component are specified (see S11 in FIG. 3), and the old drawing number of the component use target is used. After inputting the new drawing number using the keyboard of the display device 23 or 27 (see S12 in FIG. 3), the design parts table 32 using the old drawing number is searched for the old parts and counted. (Number of old parts used) (See S13 in Fig. 3)
Is registered in the unprocessed counter F5 in the record format in the parts replacement instruction file 39 (S14 in FIG. 3).
reference). For example, see the unprocessed counter F5 in the record format in FIG. In this record format, the value of the changed counter F3 and the value of the change unnecessary confirmation counter F4 are registered as "0", respectively. Therefore, the part replacement processing has not been performed yet and is specified in the design parts table 32. The old part [old part specification (drawing number)] is "2
0 ". When such registration is registered for each of the old part and the new part, the registration date is registered in the registration date registration area F6, and the change deadline is the change deadline registration area F7. Registered in.

Under such a component management situation example, the revision design processing unit 38 is started (see S21 in FIG. 3), and in the revision design process, the presence or absence of a component to be replaced is checked (see FIG. 3). (Refer to S22) (corresponding to the component replacement possibility determination described in claim 1). If there is no part to be replaced (see N of S22 in FIG. 3), the same revision design processing as the conventional one is started (see S28 in FIG. 3). If there is a part to be replaced (Y in S22 in FIG. 3)
Reference), and for each of the target parts, it is checked whether or not the replacement satisfies the design specification condition or the like (S23 in FIG. 3).
reference). The component to be replaced is, for example, a component shown in the record format of FIG.
If the number of objects is three and all of the replacement conditions are satisfied, the changed counter format F3 of the record format corresponding to the part is used before the revision design processing similar to the conventional one using the part is performed. Is increased by "1" (see S25 in FIG. 3). Conversely, when none of the replacement conditions are satisfied, for example, when the production is discontinued or the special parts cannot be changed, the value of the change unnecessary confirmation counter F4 is
Only "1" is added (see S26 in FIG. 3). The changed counter F3 of the record format after the revision design processing for the part whose number of parts to be replaced is 3
Is updated from "0" to "3" as shown in the record format, and the value of the record format change unnecessary confirmation counter F4 corresponding to the part is changed from "0" in the record format to the record format. Updated to "3" as shown. In any of these update processes, the value of the unprocessed counter F5 in the record format is reduced by "1" for each of the parts (see S27 in FIG. 3). The value of the unprocessed counter F5 in the later record format is updated from "20" to "17" as shown in the record format.

The number of cases registered in the unprocessed counter F5 for the same part is 20 as described above, and all of the corresponding parts are subject to part replacement. The remaining one is a changed counter F3 of the record format and a counter F4 which does not need to be changed when the replacement condition is not satisfied.
And the value of the unprocessed counter F5 are updated to “19”, “1”, and “0”, respectively, as shown in the record format.

Such an update process is generated for each component to be replaced.

When the above-described batch change processing unit 40 is started, the conventional batch change process, that is, the designation of the target part (FIG. 3)
S32), target parts table drawing number list display (see S33 in FIG. 3), component replacement possibility selection (corresponding to the component replacement possibility determination described in claim 1) (see S34 in FIG. 3. This is performed in accordance with step S23.), And the part which can be replaced (part of FIG. 3)
In step S35, the old part such as the part name registered in the design parts table 32 is updated to the new part (see S36 in FIG. 3), and the value of the changed counter F3 is changed to the part. In contrast to increasing the number n1 of the parts that can be replaced (Fig. 3
S37), the update process from the old part such as the part name registered in the design parts table 32 to the new part is not performed for the part which cannot be replaced (see N of S35 in FIG. 3). The value of the change unnecessary confirmation counter F4 is increased by the number n2 of the parts that cannot be replaced (see S38 in FIG. 3). Regardless of whether or not the component replacement is possible, the value of the unprocessed counter F5 in the record format corresponding to the specified target component is reduced by the value n1 + n2 (see S39 in FIG. 3).

Even if a certain period of time has passed since the component change was made to the component replacement instruction file as described above (for example, when the change deadline in the record format has come), the corresponding content of the design parts list is still updated. If any of the processing has not been completed, the part change request instruction form creation processing unit 37 is activated (see S41 in FIG. 3). 3 (see S42 in FIG. 3), and outputs from the printer 28 a reminder list of the unprocessed design parts list as the reminder list of the unprocessed design parts table in the old parts specification (see FIG. 3).
S43).

Further, the deletion of the registered data of the component replacement instruction file 39 is performed by switching the entire design parts table by the component replacement instruction processing unit 35 or 52 or after confirming the switching (“0” of the value of the unprocessed counter F5). This is done automatically at the end of the period. This predetermined period is used to give an opportunity to reconsider the use of the part.

The feature of the present invention of the new design processing unit 36 in the above-described embodiment may be another alternative means, for example, a means for notifying a designer who has previously become an old part to an artificial designer. Further, among the part changes made to the above-described parts replacement instruction file, a processing method for a part whose update processing of the corresponding contents of the design parts table has not been completed may employ another reminder method. For example, a system configuration that also serves as a visual or audible alarm and display display may be used.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, a common component replacement instruction file is provided for the design BOM management subsystem and the production management subsystem, and these can be accessed from both subsystems at any time. Since the parts management system was constructed at the same time, it was possible to coordinate the parts data used between the two subsystems, to prevent parts arrangement mistakes that had conventionally occurred, and to reduce the double inventory period of specifications with different functions. Shortening can be achieved.
