And output control means 103 for outputting the pasted shape to the printer 12, the display device 13, and the like. The calculation processing unit 10 achieves the functions of the various means described above by a program stored in a storage unit (not shown). The pasting shape calculation unit 102 stores the product 40 such as a paper container in a stacking box (folding shape, etc.) and the product 40.
The pasted shape including the final assembled shape is calculated. The storage device 14 stores the development view data of the product 40 created by the graphic creation / editing device 2 and the graphic data indicating the pasted shape 60 of the product 40.

The plane figure data generating means 101 divides the developed pattern data that has been read into planes (bottom, side, etc.) having individual closed areas as minimum units, and a plane dividing section 201 for each plane. And a surface data generation unit 202 that generates surface data. Paste shape calculation means 1

The graphic creation / editing apparatus 2 is realized by CAD or the like. The development drawing data of the product 40 created by the graphic creation / editing device 2 is stored in advance in the storage device 1
Store in 4. FIG. 4 shows an example of specific developed view data of the product 40. Here, a developed view of the product 40 is shown as graphic data. Further, the graphic creation / editing apparatus 2 does not necessarily have to be connected to this apparatus. For example, the development drawing data of the product 40 created by the graphic creating / editing apparatus 2 is stored in a storage medium such as a floppy disk, and You may make it read in the pasting shape calculation apparatus 1 through a storage medium.

Next, the operation of the pasted shape calculating apparatus according to the first embodiment described above will be described with reference to the flowchart of FIG. First, in order to read the development view data of the product 40 created by the graphic creation / editing device 2 stored in the storage device 14, the graphic number (or the expansion) attached to the development view data of the product 40 at the time of storage from the input device 11 is used. A data name or the like for identifying the figure data is input (step 301). By inputting the figure number, the development drawing data of the product corresponding to the figure number is read from the storage device 14 into the information reading means 100 (step 302). Further, the development drawing data of the product 40 read from the storage device 14 is displayed on the display device 13 in a state as shown in FIG. 4, for example. Next, when the development drawing data of the product 40 is read, the surface dividing unit 2 of the surface graphic data generating means 101 based on the development drawing data.
At 01, it is divided into surfaces (bottom surface, side surface, etc.) with each closed region as the minimum unit (step 303). Next, for each divided surface, as shown in FIG. 4, data with surface numbers (for example, 1, 2, 3, etc.) and side numbers (for example, a, b, c, etc.) as shown in FIG. ) And the surface number of the adjacent surface (in the case of the surface 6 of FIG. 4, the surface number of the adjacent surface is 2,
7, 10, and 5) are included in the surface data generation unit 20 of the surface graphic data generation unit 101.
2 (step 304).

After the surface data having such a data structure is generated, next, a side to be a reference for folding the development view data is designated and input (step 305). For this instruction, for example, as shown in FIG. 6A, a mouse or the like is used to click an arbitrary side of the development view on the screen as a reference side, or the above-mentioned surface number and side number of the surface data are input. It is performed by inputting from the device 11. By this instruction, the reference side number is input. Further, it can be confirmed that the input reference side is selected by a method such as displaying the solid line changed to a wavy line as shown in FIG. 6B or displaying the line segment in a different color. To do so. In this embodiment, the side b of the surface 6 is designated and input. After the reference side (side b of the face 6) is selected, the face to be bent next is designated and input (step 306). The method of designating this surface is the same as the method of designating the reference side (side b of surface 6) described above. Further, when designating the surface, first, as shown in FIG. 6B, the surface on the folding side (the surface 6 including the reference side b) is designated. The reference side data and the surface data on the side to be bent are sent to the next-stage pasting shape calculation means 102 together with the development view data.
Next, when the surface 6 to be bent is instructed, this surface 6
The faces (face 2, face 5, face 10) adjacent to are automatically selected by the folding face determination unit 203. However, with respect to the surface 7, a reference side (side b of the surface 6) with respect to the bending side surface 6
There is a rule that is not selected because it is on the opposite side of. That is, the surface 7 is not selected here because it is the surface on the side that is not bent. After this selection, the same operation is performed on the faces 2 and 10 selected as the faces to be further bent. That is, when the surface 2 is designated, the adjacent surface 1 is selected, and when the surface 10 is designated, the surface 13 adjacent to the surface 13 is selected. By doing so, all the surfaces located on the side to be bent on the reference side (side b of the surface 6) are determined (step 30).
7). The selection of the reference side and bending surface described above is
All are performed based on the surface data generated previously. When the surface to be bent is determined, the shape calculation unit 204 uses the reference side (side b of the surface 6) as shown in FIG.
The shape when the determined surface (surfaces 1, 2, 5, 6, 10, 13) is bent is calculated (step 308). As for the shape after bending, the shape after bending is displayed by superimposing the surface to be bent on the surface that can be bent. This post-processing is calculated by repeatedly executing the processing from step 305 to step 308 until the paste shape to be calculated is obtained. The calculated pasted shape is output by a printer or the like (step 31).
0). The development drawing data created by CAD etc. is not suitable for the bending process of the surface because the whole data structure is one unit.
Therefore, special data processing is required, and this processing is extremely complicated. In the pasting shape calculation device of this embodiment,
While reading the development view data, the development view data is divided into individual surfaces to automatically generate surface data. Then, by using the generated surface data, the folding process of the development view can be easily performed.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not necessarily limited to the above embodiments. In the above-mentioned embodiment, the storage shape when storing the product 40 in the stacking box was calculated,
The final assembly shape of the product 40 may be calculated. The calculated assembly shape 70 is shown in FIG. When calculating the assembly shape 70, in addition to the above-described calculation process (steps 301 to 309), after instructing the bending angle of the surface and the like, the processed data is converted into a three-dimensional form to assemble the product 40. The shape may be displayed.
