Method for improving cutting utilization rate of glass

Abstract

The invention relates to a method for improving the cutting utilization rate of glass. The method is implemented based on the size data of a target glass block and the size and defect data of an original glass sheet, and comprises the following steps: firstly, acquiring glass information, namely the data of a target glass sheet and the data of the original glass sheet, and processing and converting the glass information; and constructing a heuristic glass cutting optimization algorithm. The algorithm fully considers constraints from customers, physical characteristics of glass, insufficient production of float glass and the like, a cutting mode based on decision tree representation is creatively adopted, 1-cut, 1-plate and 1-solution are sequentially generated, and an optimization target is continuously changed through multiple loop iterations, and finally, an optimal cutting scheme is found, which is accurate and efficient.

Description

【Technical field】 [0001] The invention relates to the technical field of glass manufacturing, in particular to a method for improving the utilization rate of glass cutting. 【Background technique】 [0002] Most flat glass is produced by a process called "float". In this process, various powders (sand, soda ash, ...) are melted in a large furnace to form liquid glass, which is then spread over tin baths, cooled and solidified, and then cut into large glass plates. These large glass panels are then stacked on bottom racks and sent to conveyor belts. Generally, large glass sheets need to be cut into smaller rectangular pieces of glass to suit the customer's needs. When cutting large sheets of glass into smaller sheets, both customer-related constraints (orders...) and the physical properties of the glass must be fulfilled. Also, the quality of large glass sheets is not perfect, with inherent defects created during the "float" process. During the cutting process, when the def...

Also, the quality of large glass sheets is not perfect, with inherent defects created during the "float" process

During the cutting process, when the defect is on the cut glass sheet, it is likely to be returned due to loss of quality

In this case, it is necessary to re-cut glass pieces of the same size, which reduces the productivity of the production line. Now a method to improve the utilization rate of glass cutting is proposed.
