Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet material collecting and managing device used for collecting one or a plurality of plate-shaped products of different sizes from one rectangular plate-shaped material. is there.

[0002]

2. Description of the Related Art For example, when a product of a smaller size than a square (square or rectangular) material (for example, a steel plate) having a flaw is cut out, it is necessary to avoid the flaw. In the case of performing such work, conventionally, the measurement of a product order for a material is manually performed from the end of the material (this is to leave an area that can be effectively used even a little), and one or more products are We are cutting out (collecting) orders.

In the above description, a steel plate is taken as an example,
Other than this, it is common to all sheet-shaped materials such as glass plate, metal plate, resin plate, and apparel. In addition, depending on the product, there may be cases where the reason for sampling and removal is the reason for flaws or other than flaws (for example, wrinkles, unevenness, bending, bubbles, inclusion of foreign matter, discoloration, deterioration, etc.).

[0004]

However, in the above-mentioned prior art, since the method of measuring the product order for the sheet-shaped material is planned manually, the work efficiency is low and the yield of the collection is low. There is a limit to improvement.

It is an object of the present invention to automate the work when collecting at least one plate-shaped product of different size from one rectangular sheet-shaped material and to improve the yield of collection. To provide a collection management device.

[0006]

In order to achieve the above object, the present invention is for collecting at least one sheet product having a size smaller than the sheet material from one square sheet material. When creating the sampling data, the maximum size in the defect-free area of the material is determined based on the product order data, the data of the sheet material to be divided, and the position and shape data of the defects of the sheet material. The sheet product which can be taken is selected and divided, and the remaining area is provided with a processing means for making a new sheet material to be divided.

Further, when the sheet product is selected, it is judged whether or not the unusable area due to the defect is within the allowable range so that the unused area generated in the sheet material is minimized, and the processing is executed. I am trying to do it.

Further, in order not to use the processed data by mistake, the data relating to the sheet material before the division for which the sheet product has been collected is erased from the storage medium.

[0009]

[Function] According to the above-mentioned means, the product order data from the customer or the like, the sheet material to be divided (the sheet material of the division source)
Based on the data and the position and shape data of defects such as flaws that the sheet material has, sheet products are automatically produced from the sheet material so that the unused area is minimized and the product does not include defective portions. The process of dividing (collecting) is performed. Therefore, the sampling with the highest yield is automatically performed without manual work.

When the sheet product is collected from the original sheet material, it is desirable that the sheet product is cut out so that the unused area is minimized. Therefore, by determining whether or not the unusable area including the defect is within the allowable range and executing the processing, the unused area can be minimized.

Further, by erasing the data relating to the sheet material before the division for which the sheet product has been collected from the storage medium, the processed data will not be erroneously used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a flow chart showing a processing example of a sheet material collecting and managing apparatus according to the present invention, and FIG. 2 is a block diagram showing a principle configuration of the sheet material collecting and managing apparatus. 3 to 5 are explanatory views showing a sampling method according to the present invention. In addition, in the following, a steel plate will be described as an example.

As shown in FIG. 2, the sheet material collection management device 1 is connected to the material cutting device 2 through a line 3 (a telephone line, a dedicated communication line, etc.). The material cutting device 2 includes a table and a cutting blade for vertically and horizontally cutting a material, and the cutting position is determined by the sheet material collection management device 1. The sheet material collection management device 1 also includes a general-purpose CPU 4 that controls the drive unit of the material cutting device 2 and an AI (Artificial Int) for performing the processing shown in FIG.
elligence) CPU 5 is provided, and a language such as Lisp can be used for the software.

Next, the processing of FIG. 1 executed by the AICPU 5 will be described with reference to FIGS. In addition, S in FIG. 1 represents a step.

First, the sheet material sampling management device 1 includes product order data (specification contents, etc.), material data (materials, size, quality, etc.), defect data indicating which part has a defect such as a defect.
(S101). Then, the first material is used as the only divided material (S102). This is to select a material that meets the specifications and has a larger size than the ordered product as the material to be cut (divided).

Then, it is judged whether or not there is a combination as shown in FIG. 3 for a certain divided material 6 (S).
3). If there is, a certain product order 7 is defective (X in the figure
If there is a product order 7 that can be sampled without the (mark) 8 and the remaining dimensions in each of the vertical and horizontal directions after the sampling are within the predetermined allowable dimensions, the divided material 6
Further, the product order 7 (shaded portion) is collected, and the divided material 6 that has been collected is erased (S104). Then, the divided material 6 has been used and there is no space for collecting products other than the product order 7, so it is deleted from the data.

If the combination shown in FIG. 3 does not exist, as shown in FIG. 4, another product order 10 can be collected from another divided material 9 without any defect, and the vertical length after the collection can be obtained. Then, it is judged whether or not there is a product order 10 in which the remaining dimension in any of the horizontal directions is within a predetermined allowable dimension or less (S105). To collect. Then, since the small pieces (corresponding to the remaining length in the vertical direction) after collection are so small that they cannot be reused, the divided material 11 is deleted from the data
A rectangular plate having a side remaining larger than the allowable dimension as one side is defined as a new division material 12 (including the defect 8 in this example) (S106).

If the combination shown in FIG. 4 does not exist, it is judged whether or not the combination shown in FIG. 5 exists (S107), and if it exists, as shown in FIG. The order 14 is collected and the collected divided material is deleted. Then, the two rectangular plates made from the remaining divided materials are used as new divided materials 15 and 16 (S10).
8). If it does not exist, the process ends.

If there is no product order that can be collected from the divided material by performing the above processing, all the processing is ended. If there are product orders that can be collected, the process returns to step 103 and the subsequent processing is repeatedly executed. . Then, based on the result of the above processing, the material cutting device 2 is driven,
The product order is cut out (collected).
