Abstract

PURPOSE:To represent the plural parts of similarity or the same shape on one drawing together with a parts table by storing parts designing information on a parts designing information table and using the drawing parametric- displayed as the drawing. CONSTITUTION:For parts designing information table fetching processing 12, parts input information fetched into an electronic computer is stored in a parts designing information table 19. For summing up processing 15, the stored information is pulled out and when the parts of the same drawing number and the same mold number exist in it, the summing up of the number of the whole is executed and is add-stored in the table 19 and parts design is prepared. For designing information output control processing 16, parts designing information is pulled out of the table 19 and only when the plural kinds of the parts designing information of the same drawing number exist in it, control processing is executed so that the whole parts designing information may be outputted on the one drawing. Thus, a designing manday, a drawing manday and a parts table preparing manday can be reduced broadly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a processing method for automatically creating a parts list using an electronic computer, a graphic output device, and a visual display device.

[Conventional technology]

Manufacturing a product requires many drawings and a bill of materials for the parts that make up the product. Conventionally, when a product is designed by hand, a bill of materials is created manually based on product or component design information written in drawings. Furthermore, when designing a product using a CAD system, a bill of materials is created by manually inputting a large amount of design information for manufacturing the product as input data.

In addition, in the processing method for automatically creating a parts list proposed in Japanese Patent Application Laid-Open No. 63-219075, parts list information is imported from the parts list data database, drawing information is imported from the graphic database based on the parts list information, and the parts list information is created. By automatically adding parts and issuing a bill of materials, the design and drafting man-hours and time required are reduced, and work errors are eliminated.

The former method of manually drawing a design or inputting data requires a large amount of design man-hours, drafting man-hours, or number of inputs, and there are problems in that it is easy for the operator to make operational errors.

On the other hand, although the latter improves the above-mentioned drawbacks to some extent, it still poses a problem when the number of parts increases in a complex product. That is, as the number of drawings increases, a large number of drawing man-hours are required for manufacturing, parts arrangement, management, etc. Particularly many similar or identical parts,
It is even more difficult to manage parts where only part of the machining dimensions change each time.

[Problem to be solved by the invention]

The present invention solves the problems described above, such as the large amount of man-hours required to create a bill of materials manually and the possibility of drawing errors on the part of the operator, and facilitates drawing or design work. The first purpose of this invention is to provide a method for automatically creating a parts list.

A second object of the present invention is to reduce the increasing number of drawings and provide efficient parts drawings in the conventional automatic parts list creation processing system.

[Means to solve the problem]

The present invention has the following means to achieve the above object.

That is, input part input information is stored in a part design information table, product information registered in advance based on the part input information is extracted and additionally stored in the part design information table, and stored in the part design information table. The drawing number registered in advance is extracted based on the information stored in the part design information table, and is additionally stored in the part design information table, and the same parts are totaled based on the information stored in the part design information table, and the total number of parts is calculated. is additionally stored in the parts design information table, a parametrically displayed parts diagram registered in advance is selected, and the part design information stored in the parts design information table is written and output at a predetermined position of the parts diagram. Parts list automatic creation processing method % formula % Part design information consisting of input part input information, pre-registered product information, drawing number obtained from the drawing number master file, number of parts obtained from aggregation, and fixed values. By using a drawing that is stored in a parts design information table and parametrically displayed as a drawing, it is possible to represent a plurality of parts that are similar or have the same shape together with a parts list on one drawing. In this way, what was conventionally represented as multiple drawings can be represented as one drawing. Further, since the part design information stored on the part design information table is displayed as a table on the drawing, efficient processing in terms of manufacturing, parts arrangement, and management becomes possible.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings. The embodiment shown here shows an automatic parts list creation processing method for creating a box by sheet metal processing.

FIG. 1 is a block diagram showing an embodiment of the automatic parts list creation processing method of the present invention. In this figure, the input information importing process 11 performs a process of importing into the computer the part input information of the parts constituting the product or all the parts attached to the product instructed by the visual display input device 24. Here, the input information is design information that specifies parts that cannot be obtained from product information.

Next, a component design information table import process 12 performs a process of storing the component input information imported into the computer into a component design information table 19 whose details are shown in FIG.

In various parts design processing 13, product information is extracted from the product information file 20 registered in advance based on the part input information, part processing data is created, and the created part processing data is added to the part design information table 19. Remember. Through the processing up to this point, information that can be used to design the part, such as the model number and processing method obtained from the number of dimensions and the part name, is created. The information stored in the component design information table 19 is shown in FIG. In this figure, 31 is a column showing the part name, 32 is a column showing the drawing number stored in later processing, 33 is a column showing the model number, 34 to 40 are columns storing the dimensions of each part, and 41 is the number. This is a column that represents

As shown by the paddle 42, each piece of information is obtained as input information, obtained from product information, or obtained as a fixed value.

The next drawing number search process 14 is the part design information table 1.
9, the stored information is extracted, the drawing number corresponding to each part is searched and selected from the drawing number master file 21 based on the information, and the drawing number is added to the column 32 of the parts design information table 19 and stored. Perform processing.

A totaling process 15 extracts the information stored from the parts design information file 19, and if there are parts with the same drawing number and the same model number, the total number is totaled and additionally stored in the parts design information table 19. If there are no identical items, no aggregation processing is performed and no processing is performed. The information stored in the component design information table 19 in this manner will be referred to as component design information.

The design information output control process 16 includes the component design information table 1.
9, part design information is extracted, and only when there are multiple types of part design information with the same drawing number, a second control process is performed to output all the part design information on one drawing. FIG. 3 is an example of screen output, and in this case, four types of part design information having the same drawing number are displayed in the parts list. If there are 6 or more types but less than 10 types, another drawing with the same drawing number will be prepared, and the 6th to 1st drawing will be added to that drawing.
The 0th part design information is output. In this process, up to 5 types of part design information are output to one drawing, and when 5 types are exceeded, the information is output to the next drawing with the same drawing number, and thereafter, when 5 types are exceeded, the drawings are output one by one in the same way. We will carry out processing to increase the number of

The design information coordinate processing 17 performs processing for determining coordinate values for outputting part design information on a part diagram based on the information obtained in the previous processing, the design information output control processing 16. In the embodiment, the drawing number is extracted from the part design information table 19, and since there is an output coordinate value specific to the part drawing, the output coordinate value is determined based on the drawing number.

The design information output process 18 generates a parts design to be output to the parts list of the parts drawing based on the information in the design information output control process 16, the information in the design information coordinate process 17, and the information from the parts design information table 19. The information is output to the drawing file 23, the parts drawing data is extracted from the parts drawing file 22 using the drawing number as a search key, and the processing is performed to output it to the drawing file 23.

Therefore, the drawing data is extracted from the drawing file 23,
A parts diagram/parts list 26 is created from the graphic output bag W25.

The parts diagram data registered in the parts diagram file 22 is
As shown in FIG. 3, drawings designed using parametric representation are registered. In addition, a parts table frame is created for each parts diagram.
