Automatic stock layout method of insulated paper board

Abstract

The invention discloses an automatic stock layout method of an insulated paper board, which includes the following steps: (1) selecting a rectangular insulated paper board from a part warehouse and extracting relevant information of parts; (2) selecting rectangular plates from a plate warehouse and extracting relevant information of the plates; (3) encoding obtained information to obtain a plurality of solutions; (4) decoding the plurality of solutions one by one by using remaining rectangle filling algorithm to obtain use rate of the solutions; and (5) performing optimization continuously ona stock layout process by using genetic algorithm and outputting an optimum stock layout scheme correspondingly. By means of the automatic stock layout method, process requirements of stock layout ofthe insulated paper board can be met well, and an optimized stock layout scheme can be found fast and efficiently by combining heuristic algorithm and intelligent algorithm, therefore material use rate of enterprises is greatly improved, stock layout time can be shortened greatly, and stock layout efficiency is improved.

Description

technical field [0001] The invention relates to the field of nesting of workpieces, and more specifically, to an automatic nesting method for insulating cardboard. Background technique [0002] With the continuous improvement of social productivity, the scale of production continues to expand, and the consumption of raw materials is also increasing. In the production of many products, the blanks of parts are obtained from plate loading and unloading, and the price of raw materials has risen sharply, which has led to a significant increase in the production cost of enterprises. Rising profits, falling profits, and some companies even suffered losses. my country's manufacturing companies are facing unprecedented challenges. The nesting problem is a common problem encountered in the production practice of metal manufacturing, paper making, glass manufacturing, automobile manufacturing and other manufacturing industries. Effective nesting methods can enable enterprises to optimal...

Problems solved by technology

This traditional production method of manual layout and cutting has obvious disadvantages. Firstly, it causes a large amount of leftover material. There is a serious waste of raw materials in the enterprise; secondly, there is a large backlog of raw materials in the enterprise, and the capital occupation is serious. The reason is that the enterprise cannot achieve the layout budget

In order to ensure continuous production, it is necessary to purchase various types of raw materials as inventory; again, the cutting and blanking production process is in a state of disorder and disorder, and it is difficult to manage the cutting and blanking production process of the sawing machine and shearing machine at regular intervals, resulting in cutting and blanking. The material production efficiency is low, and the plate waste is serious

[0004] Moreover, specifically for the manufacturing process of insulating cardboard in the form of rectangular parts, the existing optimized layout methods often do not take into account the special process requirements of insulating cardboard—the fiber direction, the rectangular shape that can be spliced ​​with each other, and the “one size fits all "(The so-called one-size-fits-all means that the cutting equipment of insulating cardboard, such as band sawing machine and shearing machine, can only be cut along a certain direction during processing until the cutting is completed), so it cannot be applied to the optimal arrangement of insulating cardboard. Sample

Manual layout of insulating cardboard is inefficient and the layout effect is not ideal. Therefore, how to formulate processing requirements that better meet the processing requirements of insulating cardboard and make more effective use of raw materials according to the specific process requirements of insulating cardboard and its own characteristics , significantly lower cost and more efficient nesting method has become an urgent technical demand in the industry
