Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a component arrangement method used when using an NC laser cutting device, an NC gas cutting device, etc.

(Prior Art) Conventionally, when cutting various types of parts from a flat material using an NC laser cutting device, an NC gas cutting device, etc., as a method for arranging parts, first, an interactive method with a computer is used. Create graphic data for one part by inputting graphic element information such as a line segment, two arcs, etc., repeat this process to create multiple types of graphic data, and then create the graphic data for material collection. A commonly used method is to create part placement data by sequentially specifying parts and displaying them on the screen, and then moving the figures of each part on the screen through interactive input with a computer.

(Problems to be Solved by the Invention) According to the method described above, when the types and quantities of parts to be nested are relatively small, an operator can easily obtain component placement data with high yield. can be created. However, when there are many types and quantities of parts to be taken, and multiple materials must be used to take all the parts, it takes a lot of time to create high-yield part placement data. It had the disadvantage of requiring

Therefore, the seventh object of the present invention is to automatically create parts equipment data with a yield of 155 in a short time even for a large number of parts of such a large variety and quantity that multiple types of materials must be used. Provides a method for arranging parts.

[Configuration of the Invention (Means for Solving Problems)] The present invention provides a shape master updating/shape recognition means for recognizing the approximate shape of a part and registering it as shape data in a computer;
Intermediate file creation means that extracts information such as materials and quantities necessary for manufacturing products and registered graphic data and stores them in an intermediate file, and shapes of parts other than rectangular parallelepipeds among the graphic data stored in the intermediate file. packing means for collectively changing the data into rectangular shape data with a minimum area;
A nesting means that selects materials based on elements such as material and plate thickness from the graphic data compiled by this packing means and automatically arranges them for material collection, and displays the results of the arrangement by this means. The present invention is characterized by comprising a placement result display means for displaying the result on the device.

(Function) According to the above means, the computer automatically creates part arrangement data for material collection, so when there are many types and quantities of parts, it takes multiple materials to take all the parts. Even when it is necessary to use this method, high-yield component placement data can be created within a short period of time.

(Example) An example of the present invention will be described below with reference to the drawings. The computer 1 is roughly divided into a figure master update/shape recognition means 2 and an automatic nesting means 3. Then, the automatic nesting means 3 includes the intermediate file creation means 4.
, a packing means 5 , a nesting means 6 , and an arrangement result display means 7 .

On the other hand, between each means there is a graphic element file 8, a graphic data file 9, a component configuration file 10, and an intermediate file 1.
1 and a board refile 12.

The graphic element file 8 stores graphic element information such as line segments, two circular arcs, etc. representing the shape of a newly created component for each component. Further, the graphic data file 9 stores graphic element information of parts registered in the past and graphic data in which the shapes are recognized as basic shapes such as triangles, rectangular trapezoids, etc. Furthermore, the parts configuration file 10 stores component configuration data such as materials and quantities of parts that make up the product.

The intermediate file 11 stores nesting shape data showing the shapes of all parts manufactured this time as rectangular parallelepipeds, and data such as the material and quantity of each part. In addition, the board cutting aisle 12 stores arrangement data such as the position of parts arranged for each material, the yield in each direction, and the like on large plates of material having different dimensions.

Now, the figure master update/shape recognition means 2 reads the figure element information of the newly created part from the figure element file 8, and converts the figure element information into basic shapes such as triangles, rectangular parallelepipeds, trapezoids, etc. that have the minimum area. The graphic element information and the graphic data are registered in the graphic data file 9.

When the type and number of products to be produced this time are entered into the computer in an interactive manner, the intermediate file creation means 4 creates a parts configuration file containing information such as the number and type of parts required to produce those products. 10 and outputs the part creation information obtained by multiplying it by the number of units to an intermediate file 11. At the same time, the intermediate file creation means 4 stores the graphic data of various parts to be produced this time in a graphic data file 9.
, and output it to the intermediate file 11.

The packing means 5 reads figure data and number data from the intermediate file 11, extracts parts whose figure data has a basic shape other than a rectangular parallelepiped, and whose production quantity is a plurality, and extracts the figures of these plural parts. The data is changed so as to be automatically arranged so that it can be recognized as rectangular parallelepiped graphic data with the minimum area, and the modified rectangular parallelepiped graphic data is output to the intermediate file 11.

The nesting means 6 reads the part preparation information such as material and thickness stored in the intermediate file 11 and the figure data, and selects the material of the large plate according to the material and thickness set in advance in the nesting means B. The material to be used is determined from among the material data of
Layout for material picking is automatically performed based on the graphic data from , and parts placement data is output to the board cutting file 12 each time material picking for one large board is completed.

When the nesting means 6 completes the arrangement for collecting the amulet, the arrangement result display means 7 reads out the arrangement data and the graphic data from the temporary collection file 12 and the graphic data file 9, respectively, and displays the layout diagram. In addition to the layout drawing, the placement result display means 7 displays a yield display and a blanked parts list including the type and quantity of the placed parts.

Then, cutting of the material is performed based on the arrangement displayed on the arrangement result display means 7.

According to the method described above, by inputting the graphical element information of the part to be created into the graphical element file 8, and inputting the type of product to be produced this time, such as the number of two units, etc. into the intermediate file creation means 4, the material collection for the large plate material can be performed Because this process is performed automatically and high-yield component placement data is created, a high yield can be achieved in a significantly shorter time than with the conventional method in which parts are placed while moving shapes on the screen using operator operations. It is possible to create component placement data.

[Effects of the Invention] As is clear from the above description, the present invention provides a computer with a figure master update/shape recognition means for recognizing the approximate shape of a part and registering it as figure data, and a material necessary for manufacturing a product. , ・An intermediate file creation means that extracts information such as quantity and registered graphic data and stores it in an intermediate file, and a minimum area of the graphic data of parts other than rectangular parallelepipeds among the graphic data stored in the intermediate file. A packing means changes the shape data into rectangular parallelepiped shape data, and the shape data compiled by this packing means selects materials based on elements such as material and plate thickness and automatically arranges them for material collection. Since it is characterized by comprising a nesting means and a placement result display means for displaying the placement result by this means on a display device, it is possible to use a large variety of materials in such a large number that multiple types of materials must be used. This has the excellent effect of automatically creating high-yield component placement data even for parts in a short period of time.
