Abstract

PURPOSE:To realize an efficient working process and the economic manufacture of a sheeting product, in which the yield of a material is set to be maximum, by arranging plural kinds of different products in optimum on the prescribed material and generating NC data which makes the die change of a working to be minimum. CONSTITUTION:Inputted product data which are to be worked is read from a storage part 2, and the products of the same material and plate thickness are selected, whereby the products are selected in the order of less die change frequency. The threshold of the change frequency is set in several steps in consideration of the time of the working and a die change process, and product groups are selected for respective steps. Then, the product group for the steps of the selected threshold are laid out on the material of a regular size in such a way that the yield becomes maximum, and a prescribed decision value is provided for the yields of all the layouts after products 21-23 arranged on the material of the regular size 20. A decision whether they reach the decision value is executed. When the decision value is satisfied, they are stored in a storage part 2. Thus, optimum product arrangement in which the die change process is minimum and the yield is maximum can be obtained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a product array processing device, and in particular, it is used to predetermine a large number of different products to be processed in sheet metal processing using a numerical control (hereinafter referred to as NC) device. This invention relates to a product array processing device that efficiently takes out materials of size.

[Conventional technology]

Since 1; C, this type of product array processing apparatus has generally created array information by allocating a plurality of processed products of the same type onto a single material plate of a predetermined size.

Furthermore, when processing the same type of processed product, it is necessary to replace dozens of different processing dies. Therefore, different types of products are produced by sheet metal processing with a high yield from predetermined length materials, and a process plan is manually created to minimize the need for mold replacement.

[Problem to be solved by the invention]

The above-mentioned conventional product array processing device does not waste multiple types of materials when specifying the required number of different types of products to be processed, or when allocating similar types of products to one material cup. This method has the disadvantage of producing more products in stock than necessary. Furthermore, creating a rational process plan manually has the disadvantage of requiring a large amount of man-hours.

[Means to solve the problem]

The product array processing device of the present invention is a product array processing device for arranging different kinds of products when manufacturing a large number of different kinds of products from fixed-length materials in sheet metal processing, and the drawing number and quantity of each of the many different kinds of products to be processed. an input means for inputting a designation code such as, a storage means for storing data such as materials, molds used, dimensions, etc. of each of the large number of different products; Based on the data read from the means, mold change minimum processing data for grouping a large number of different types of products to be processed for each predetermined mold change frequency and the mold change minimum processing data are combined into one element. The apparatus further comprises a processing means for creating product arrangement data such that the product arrangement on the standard length material has a maximum yield, and an output means for displaying and printing the data of the processing means after being stored in the storage means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. The product array processing apparatus 10 of the embodiment shown in FIG. Product material.

A storage unit 2 that stores master data files such as plate thickness, shape dimensions, and sheet metal processing molds used, and also stores processing results, and optimally arranges products on specified length materials, and
It is comprised of a processing section 3 that performs arithmetic processing for minimum mold replacement, and an output section 4 that displays and prints the processing results, such as the product layout on the standard length material, yield determination values, and the like. Also,
The control device 5 reads the sheet metal processing data from the product array processing device 10 and drives the sheet metal processing device 6 to perform optimal sheet metal processing with less loss of standard length material and fewer sheet metal mold changes. The layout diagram in FIG. 3 shows A and B on the standard length material 20 obtained in this example.

An example of the layout of C, D, and E products 21 to 25 is shown.

Next, the operation of the processing section 3 of this embodiment will be explained. FIG. 2 shows a flowchart of the operating procedure of the processing section 3.

First, product data to be machined input from the keyboard 1 is read out from the storage section 2, and products of the same material and plate thickness are selected. Further, as shown in FIG. 3, products having the same size Q are selected (step 5-1). Next, these selected products are selected in the order of products that do not require mold replacement, that is, products with fixed molds, and products whose molds are replaced less frequently. The threshold for this replacement frequency is the processing time.

Several steps are set in consideration of the mold exchange process, and a product group is selected for each step (step S
-2>6 Next, in step S, the product group for each step of the threshold value selected in step S2 is placed on the standard size material to maximize the yield of the standard size material 20 as shown in FIG. (Step 5-3). In this case, the number of products to be manufactured is also calculated and the optimal arrangement is set. Next, a fixed determination value is set for the yield of all layouts after the products 21 to 23 arranged on the standard length material 20, and it is determined whether this determination value has been reached (step 5-4). If the determination value is satisfied, the data is stored in the storage unit 2 as layout data of a mold processed product corresponding to one mold replacement frequency (step 5-5). If the yield judgment value has not been reached, an alarm is displayed (step S-4).
A).

The procedure of steps S-2 to S-4 is repeated for each mold replacement frequency setting value to create data. Therefore, for example, product groups A, B, and C are product groups that use fixed molds, and product groups D and E are product groups that require less frequent mold replacement, such that the mold replacement process is minimized, and A product arrangement of f&appropriate that maximizes the yield can be obtained. Next, when the product arrangement work using the same standard-length materials is completed, the same procedure is performed for standard-length materials of different materials and thicknesses.

〔Effect of the invention〕

As explained above, the NC-type product arrangement processing apparatus of the present invention optimally arranges a plurality of different products on a predetermined material, and creates NC data that minimizes mold replacement during processing. This has the effect of realizing economical manufacturing of sheet metal processed products with efficient processing steps and maximum material yield.
