Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a management system for a design parts list that extracts component information from design drawings, and in particular, even if a drawing is revised due to a design change in a child drawing, the top This invention relates to a parts list management method that eliminates the need to revise drawings.

[Conventional technology]

As shown in Fig. 5a, the design drawing has a title block P and a parts composition column Q, and the title block P contains the name of the item in the design drawing ("Bolt Set" in Fig. 5a),
The drawing number "A", version number "01", designer name, date, surface area, weight, etc. are entered, and in the component composition column Q, the item number (in Fig. 5 a), child drawing number "a" are entered. ”,
``b'', the version number of the child drawing number ``01'', ``01'', the number of pieces (for each part, 1 in Figure 5a), etc. are written.

Separately, as shown in FIG. If such a part is constructed, a column for its parts composition is further provided, and the drawing number, version number, designer's name, date, etc. are written in the same way as in the drawing of FIG. 5a.

[Problem to be solved by the invention] In this case, if there is a design change in the child drawing, for example, the material changes, the version number of the child drawing will also change, for example from "01" to "02". , the version number of the parent drawing must be changed accordingly, for example from "01" to "02".

In other words, if the drawing has version numbers for both the parent drawing number (the drawing number in the title block) and the child drawing number (the drawing number of the component item), the component item can be specified in detail, but when the design is changed, the drawing of the component item If you revise it, you will also need to revise the higher-level drawings. Furthermore, when a parts list is created from the above drawings, the number of data items in the parts list increases because information on all revised drawings is input every time a design is changed.

[Means for solving problems]

In a parts list management method that extracts parts information from a drawing database and edits it to manage parts, a first drawing number corresponding to drawing data representing an item composed of multiple parts and each of the above parts are used. a second drawing number corresponding to the drawing data represented; an item data holding unit storing version number data indicating the version number of the data in the first drawing number and the second drawing number; a product configuration data storage unit that stores each drawing number individually in correspondence with each other, a parts list file consisting of a parts list file, an inquiry processing unit that queries the parts list file and outputs the query results, and updated item data. a change processing unit that stores the updated version number in the data holding unit, a parts list access processing unit that accesses the parts list file, and a latest version item that accesses the item data holding unit and searches for the latest version item. When specifying a certain item and inquiring about the parts that make it up, the parts list access processing section accesses the product configuration data holding section and recognizes the parts that make up the item. The present invention is characterized in that data regarding the recognized part, which is specified by the latest version number item search processing part, is extracted from the item data holding part and output.

[Effect]

According to the present invention, a version number is set for a parent drawing number, but no version number is set for a child drawing number written in the component composition column of the parent drawing number, so design changes can be made. There is no need to revise the parent drawing even if the version number of the child drawing is revised due to such reasons. Moreover, when outputting the parts list of the parent drawing number, the latest version of the child drawing number can be automatically output.

〔Example〕

Before describing the configuration of an embodiment of the present invention in detail, its outline will be briefly explained with reference to FIG. 4.

In FIG. 4, when the parent drawing number of the parent drawing 30 is A and the child drawing numbers are a and b, the data for each item (drawing number, version number, etc.) to be used from the title column P and parts composition column Q, i.e. An item file 7-1 in which item data DM-0 is entered and a product configuration file 7-2 indicating that the product with parent drawing number A is composed of products with child drawing numbers a and b are created. Note that a bill of materials is constituted by these item data and product configuration data, and the bill of materials in the present invention means a set of these item data and a set of product configuration data. An item is a general term for individual items (products, assemblies, semi-assembled products, parts, etc.) that are subject to design, manufacturing, and production management. The product configuration file 7-2 contains the version number of the parent drawing number and the number of used products (parts) shown in the child drawing number (a is 1 in Figure 4).
, 2 b), etc. are entered. In this state, when child drawing number a is revised, for example due to material change, as shown in child drawing 31, the revision information of child drawing number a, that is, the latest version number of child drawing number a is "02". This is added to the item file 7-1 and the item data is updated to DM-1. When inquiring about the parts list of drawing number A in this state, first check the latest version number A- from the latest product configuration file 7-2.
By accessing "01" and recognizing that the component parts are a and b, and accessing these a and b from item data DM-1, the version number of a is "02" and the version number of b is Since it can be seen that the number is "01", the parent drawing number A is shown on the display section 32.
It is also possible to obtain necessary data such as the latest version number of child drawing numbers a and b that constitute this.

Next, in the present invention, (1) parts list creation control and (2)
Each of the parts list management controls will be explained.

(1) Parts list creation control First, the drawing data including the title column P and parts composition column Q is stored in the drawing database 1 shown in FIG. The parts information extraction processing section 2 extracts only parts information from these drawing data.
For example, from the data of the parent drawing 30 in Figure 4, the parent drawing number A, its version number 01, and the child drawing numbers a and b of this parent drawing number.
etc., and from the drawing with the child drawing number, its drawing number and version number, and if this drawing further has a parts composition field, its grandchild drawing number, etc. are extracted. The contents of these parts information are checked by the parts information check processing section 3.

This checked parts information is stored in the item file 7-- shown in FIG. 4 by the parts information editing processing section 4.
1 as item data DM-0, and the parent drawing number set processing unit 5 sets it as product configuration data DS-0 in the product configuration file 7-2 shown in FIG. be done. And these item data DM−
0 and product configuration data DS-0 are stored in the parts list file 7 by the item data/product configuration data output processing section 6, and a parts list is created. Now, when the version number of child drawing number a has been updated to "02" as shown in child drawing 31 shown in Figure 4, if you perform the parts list creation process in (1) again, item data will be added. From DM-0 to DM-1.

(2) Parts list management control The parts list file 7 shown in FIG. 3 stores the parts list created in the above (1). When inquiring the parts list 7 by specifying an item having the drawing number A, the drawing number A is input to the inquiry processing section 11 from the terminal device, for example, the display section 32 thereof. As a result, the inquiry processing unit 11 has been set in advance by the user to instruct access to the parts table 7 in, for example, multi-stage expansion mode, and thus requests the parts table access processing unit 15 to perform multi-stage expansion processing. As a result, the parts list access processing unit 15 first reads the item file 7-1, detects the latest version number "01" of the data of drawing number A, and then reads the product configuration file 7-2 for the part of its child drawing number. Recognize that the configuration is a and b. During this processing process, the parts list access processing unit 15 sends the latest version number item search processing unit 16 to find the latest version number items based on the item data read out from the parts list 7 by the parts list access processing unit 15. Request processing to detect from the parts list. As a result, the latest version number item search processing unit 16 detects the point where the figure number changes from the item data DM-1 in FIG. 4, for example, and searches for the figure number and its version number immediately before the change as the latest version number. . In this way, in the example of Figure 4, it is possible to detect that "01" is the latest edition for figure number A, "02" for figure number a, and "01" for figure number b. Can be done. As a result, the inquiry processing unit 11 not only outputs display data for displaying figure numbers A, a, b and their latest versions on the display unit 32 in FIG. 4, but also outputs these data as necessary. It can be printed out using the printer 33.

Next, FIG. 1 shows characteristic parts of the present invention.

The item file stores item data DM regarding drawing numbers A, a, b, a, and b, and the product configuration file stores product configuration data DS, so that drawing number A is composed of child drawing numbers a and b. has been
It can be seen that figure number a is composed of child figure numbers a and b. Here, figure number a has a relationship equivalent to a so-called parent figure number with respect to figure numbers A and B, and figure number A has a relationship equivalent to a so-called parent figure number with respect to figure numbers a and b. (see Figure 1b). Further, the parts list multi-step inquiry circuit 20 performs a multi-step inquiry regarding drawing numbers specified from the item file and the product configuration file. It is composed of a multiple item search processing section 16 and the like.

Now, as shown on the left side of FIG.
When making a query by specifying the product configuration data DS
From this, it can be seen that drawing number A has child drawing numbers a and b, and that child drawing number a further has grandchild drawing numbers a and b. According to the item data DM, the latest version number of drawing A is "01", the latest version number of drawing number a is "01", the latest version number of drawing number b is "02",
It can be seen that the latest version number of figure number A is "02" and the latest version number of figure number B is "03". in this case,
Revised to child drawing number b, grandchild drawing number a, b [b (01) → b
(02), A (01) → A (02), B (01) → B (02)
→B(03)] is performed, and then multi-step matching is performed for figure number A.

Based on these, data as shown on the same display section 32 that was inputted above is eventually output as shown in the lower part of FIG. 1a. Of course, this data can also be printed out using a printer.

〔Effect of the invention〕

According to the invention, for example, the parent drawing 3 shown in FIG.
0, there is no need to enter the version number of the child drawing in the parent drawing, and the latest version of the parts list can be automatically output. Therefore, even if the version number of the lower-order drawing number changes, there is no need to revise the higher-order drawing as in the past, compared to the case where version numbers are set for both the upper-order drawing number and the lower-order drawing number. The number of data items that need to be added when changing the design can be extremely reduced, making it easy to change the design.
