The storage shape calculation device 1 can be realized by a computer or the like. The storage shape calculation device 1 is connected to a graphic creation and editing device 2 for designing a product. Products (eg, products such as paper containers) made by the figure creation / editing device 2
Is read for calculating the storage shape.

[0008] In the storage device 14, a development pattern of a plurality of products, an ID number assigned to each development pattern, a storage shape pattern for storing the development pattern in an accumulation box, An arithmetic expression required to obtain a specific storage shape (folded shape) using this storage shape pattern, and a registered storage shape file 101 storing parameters and the like required for processing the arithmetic expression are stored in advance as a database. It is stored. The ID numbers are provided to individually identify a plurality of developed view patterns. As data for identifying the development pattern,
A pattern name or the like may be set in addition to the ID number. The storage shape pattern is provided for each development pattern. FIG. 4 shows an example of the data configuration of the registered storage shape file 101.

The calculation processing unit 10 is realized by a microprocessor such as a computer, for example, and reads a design development diagram of a product designed by the graphic creation / editing device 2 and displays the design development diagram on the display device 13;
A plurality of developed view patterns in the registered shape file 101 are read, and a developed view pattern reading means 102 for displaying on the display device 13 and, among the displayed developed view patterns, a developed view pattern similar to a design developed view are designated. Thereby, the storage shape pattern reading means 103 for reading the storage shape pattern corresponding to the developed pattern together with the arithmetic expression and the parameter, and the parameter setting means 104 for setting the value of the read parameter by input from the input device 11 And a storage shape generating means 105 for generating a specific storage shape using an arithmetic expression based on the set parameter values. The calculation processing unit 10 achieves the functions of the various units by a program stored in a storage unit (not shown).

The figure creating / editing apparatus 2 is realized by CAD or the like. The design development diagram of the product created by the figure creation / editing device 2 is stored in the storage device 14. FIG. 3 shows an example of a design development diagram of a specific product 30. The graphic creation / editing device 2 does not necessarily need to be connected to this device. For example, a design development diagram of a product created by the graphic creation / editing device 2 is stored in a storage medium such as a floppy disk, and the storage is performed. You may make it read into the storage shape calculation apparatus 1 through a medium.

Next, the operation of the storage shape calculation device according to the first embodiment will be described with reference to the flowchart of FIG. First, in accordance with a command input from the input device 11, a design development diagram of a product created by the graphic creation and editing device 2 and stored in the storage device 14 is read by the design development diagram reading means 100 (step 201). Then, the design development view of the read product is displayed on the display device 13 as shown in FIG. Next, a plurality of developed view patterns in the registered storage shape file 101 are read by the developed view pattern reading means 102 (step 20).
2). The developed view pattern is displayed on the display device 13 in the same manner as the design developed view. In addition, the displayed design development view and the development view pattern are displayed together on the display device 13 so that the shapes of the two can be compared with each other. Next, the design development diagram displayed on the display device 13 and the development diagram pattern are compared to select a development diagram pattern similar to the design development diagram of the product.
By inputting a D number from the input device 11, a development pattern is designated (step 203). Then
The storage shape pattern corresponding to the specified developed view pattern is read by the storage shape pattern reading means 102 from the registered storage shape file 101 together with the arithmetic expression and parameters (step 204). The read storage shape pattern and parameters are displayed on the display device 13.
FIG. 5 shows a display example of this storage shape pattern. In this embodiment, the surface 31 of the developed pattern shown in FIG.
The surface 32 is bent inward (side of the surface 33) at each side 35. Here, the parameters are the minimum dimensions of each part required to specify the storage shape pattern. In the present embodiment, the widths of the surfaces 31, 32, and 33 are the parameters A,
In B and C, the height is given by a parameter D, and each is given as a parameter table as shown in FIG.

An arithmetic expression to be read is an expression for generating a specific storage shape by specifying the coordinates and dimensions of the storage shape pattern based on the specific values after the above-mentioned parameters are set. It is. For example, as shown in FIG. 7, an equation (P1A0, P2E0, etc.) that defines the intersection coordinates of each side of the storage shape, and an equation (L1) that generates the side based on the defined intersection coordinates P0 P3, L2
P3, P4, etc.). Also, regarding the arithmetic expression, FIG.
As shown in FIG. 7, when there is another parameter required for generating a specific storage shape, there is an arithmetic expression (a in FIG. 7) for calculating the value of this parameter.

After the stored shape pattern, the arithmetic expression, and the parameters are read, the values of the parameters read by the parameter setting means 104 are set. Parameter A
Since the values of .about.D are determined in advance in the product development diagram shown in FIG. 3, the values are set for each parameter (step 205). The setting of this value may be performed automatically by reading the value from the design development diagram, or may be set via the input device 11. As for the values of the other parameters E required for specifying the storage shape, the values of the parameters B and C set above are substituted into an arithmetic expression for calculating E (E = BC shown in FIG. 7). Automatically calculated. As a result, the parameter E is added to the parameter table as shown in FIG.

After the parameter values have been set, arithmetic processing is executed based on the set values to generate a storage shape (step 206). More specifically, the parameter setting means sets the parameter value, A = 20, B = 4
When 0, C = 10, D = 40, and E = 30 are set, as shown in FIG. 7, equations for defining coordinates based on parameters, for example, equations such as P1A0 and P2E0 are executed. , Each intersection coordinate of the read stored shape pattern is defined. For example, as shown in FIG. 9, the intersection coordinates P1 (2
0,0), P2 (30,0) and P3 (40,0) are defined. It should be noted that, among the coordinate definition expressions, for the expression (P0) to which a value is given in advance, the value is used as it is regardless of parameters. After each intersection coordinate is defined, an expression for generating a side based on the intersection coordinates is then executed, for example, as shown in FIG. 7, an expression L1 P0 P3 or the like is executed to generate each side. Here, the expression L1 P0 P3 means that the side L1 of the start point P0 and the end point P3 is generated. For example, intersection coordinates P0 (0,0,0) defined as shown in FIG.
0) and P3 (40, 0), an edge L1 is generated. Then, each side is generated by another side definition formula, and a storage shape is generated.

The generated storage shape is displayed on the display device 13 as shown in FIG. 11 (step 207). In addition, the generated storage shape data (P0 to P6, L1 to L6)
Are stored in the registered storage shape file 101 in association with the base design development diagram (step 208). By doing so, it can be used as new data from the next time.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments.
