Abstract

PURPOSE:To manufacture a building model in a short time with high efficiency and high precision at a low cost by providing a cutting plotter which clips a part development figure from a sheet and effects grooving along a fold line according to the program command of a computer. CONSTITUTION:Data corresponding to the part development figure of a building is inputted to a computer 4 by means of a digitizer 1. The part development figure is displayed by a display device 2, and after it is confirmed that the development figure is correct, the part development figure is printed on a sheet 5. From the printed sheet 5, clipping of the part development figure, grooving along a fold line, and pasting on a paste margin are effected by means of a cutting plotter 3. Without effecting printing of the part development figure on the sheet 5, the part development figure may be clipped immediately by the cutting plotter 3 after it is confirmed that the part development figure displayed on the display device 2 is correct.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to an automatic cutting system for building models.

[Conventional technology]

BACKGROUND ART A building model (hereinafter referred to as a cardboard model) is sometimes created using corrugated paper as a preliminary work for constructing a building such as a house. Conventionally, the procedure for producing a cardboard model is to print a developed part diagram on paper by processing input data corresponding to a developed part diagram of a building on a computer, and then use the printed paper as the outline of the developed part diagram. They had to manually cut out parts along the lines, manually add grooves to the polygonal lines of the parts development diagram, and manually add glue to the glue margins of the parts development diagram.

[Problem to be solved by the invention]

However, manual cutting, grooving, gluing, and other operations require skill, making it difficult to maintain a high degree of stiffness, and requiring a long time, resulting in inefficiency and high prices.

This invention was made in view of the above circumstances, and aims to automate a series of operations ranging from the process of inputting data corresponding to the exploded parts diagram into a computer to the processes of cutting out, grooving, and gluing the exploded parts diagram. An object of the present invention is to provide an automatic cutting system for building models that can efficiently produce high-precision building models at low cost in a short period of time.

[Means to solve the problem]

The automatic cutting system for building models according to the present invention includes a digitizer that inputs various information on exploded drawings of building parts into a computer, a display device that displays the input exploded drawings of parts, and a cutting system that cuts from paper according to program instructions from the computer. The present invention is characterized by the use of a cutting plotter that performs cutting out of the exploded view of the parts, grooving along polygonal lines, and the like.

[For production]

The automatic cutting system for a building model according to the present invention is implemented, for example, in the following steps.

A digitizer inputs data corresponding to an exploded view of parts of a building into a computer and processes it, and as a result, an exploded view of the parts is printed on paper such as cardboard, and the exploded view of the parts is displayed on a display device. Ru. After confirming the exploded part diagram displayed on the display device, a cutting plotter operated by computer program commands cuts out the exploded part diagram from the printed paper, and at the same time grooves along the fold lines and glues the glue margin. be exposed.

〔Example〕

The present invention will be explained in detail below.

FIG. 1 shows a digitizer 1, a display device 2, a cutting plotter 3, etc. used to implement an automatic cutting system.

The digitizer 1 is used to input data corresponding to an exploded view of parts of a building into the computer 4. The display device 2 is used to display data input into the computer 4 by the digitizer 1, and after confirming that the exploded view of the parts displayed by the display device 2 is correct, the exploded view of the parts is displayed on a sheet of paper. printed. It is possible to print a developed part diagram on paper by replacing the canter of the cutting plotter 3 with a pen, but it is of course also possible to prepare a separate pen block and print with it. It is. The cutting plotter 3 is used to cut out an exploded view of parts from a sheet of paper 5, create grooves along fold lines, and add glue to the glue margin based on program commands from a computer 4. This cutting plotter 3 has a horizontal member 6 that moves in the X-axis direction and a vertical member 7 that moves in the Y-axis direction, and the horizontal member 6 moves in the X-axis direction and the vertical member 7 moves in the Y-axis direction. By combining this with the movement of , it is now possible to cut straight lines and curves extending in all directions with high precision. In addition, the cutter plotter 3 has a cutter in its vertical member 7, as well as
The gluing jig and the above-mentioned pen can be easily attached or replaced as needed.

Enter data corresponding to a developed part diagram of a building into the computer 4 using the digitizer 1, display the developed part diagram on the display device 2, and after confirming that it is correct, print the developed part diagram on paper 5. Then, from the printed paper 5, a cutting plotter 3 is used to cut out an exploded view of the parts, create grooves along the fold lines, and add glue to the glue margin. Instead of printing the exploded parts diagram on the paper 5, the exploded parts diagram may be cut out using the cutting plotter 3 immediately after confirming that the exploded parts diagram displayed on the display device 2 is correct. Further, when it is already known that the input data to the computer and the corresponding exploded parts diagram are correct, it is possible to omit checking the correctness of the exploded parts diagram on the display device.

When implementing such an automatic cutting system for exploded drawings of building parts, work efficiency can be improved by connecting multiple cutting plotters 3 to the computer 4, dividing the cutting work by part, and cutting each part at the same time. This improves efficiency and enables efficient model production. In addition, it is effective to securely fix the paper 5 to the cutting plotter 3 in order to cut out highly accurate exploded diagrams of parts, and for this purpose, the paper 5 must be suctioned or adhered to the fixing base 8. is desirable.

When the cutting plotter 3 makes grooves along the mountain fold lines and valley fold lines on the exploded view of the component, if the level of the cutting edge of the cutter is automatically adjusted, grooves are made while the cutting plotter 3 automatically adjusts the level of the cutting edge. When using a cutting plotter 3 that does not have such an automatic adjustment function, the paper 5
Adjust the depth of the cut groove made by the cutter by stacking two sheets. Note that it is desirable to spread a mat under the paper 5 to facilitate canting. When cutting out multiple parts at the same time as mentioned above, it is easier to assemble in the later process by assigning the same number or coloring to the joints of each part to associate them with each other. There are some advantages. In addition, by replacing the cutter of Cutting Profiler 3 with colored ink, it becomes possible to color-code each part such as the floor bones and wall parts in the exploded view of the parts, thereby eliminating the need for coloring work after assembly. It becomes like this. Note that by enabling manual operation of the cutting plotter 3, cutting errors can be quickly dealt with.

FIG. 2 shows an example in which the outer wall of a general house is divided into two exploded views of 41 parts and cut out. In the same figure, 1
0 indicates an opening such as a window or a doorway, 11 indicates a kerf forming a mountain fold line, and 12 indicates a kerf forming a valley fold line. Fig. 3 shows a building model (c) created by combining two types of parts exploded views (a).

〔Effect of the invention〕

As explained above, according to the present invention, a series of operations from the process of inputting data corresponding to the exploded parts diagram into a computer to the processes of cutting out, grooving, and gluing the exploded parts diagram can be automated, and the process can be completed in a short time. This makes it possible to efficiently produce high-precision building models at low cost.
