An access method for a large-scale printing plate storehouse plate roller access system

Abstract

The invention provides a system and a method for large-scale forme storehouse forme roller storage and taking. The system comprises conveying chains (4) and forme roller frames (1), wherein the conveying chains are connected end-to-end in a forme roller storage framework and are arranged in a vertical and slewing mode, and two ends of each forme roller frame are fixed with the conveying chains. The conveying chains are arranged along guide rails which are enabled to be used as supports for the conveying chains, a motor is used for driving the conveying belts to move circularly in a forward-reversing mode, and displacement sensors (8) used for obtaining information of moving distances and directions of the conveying chains are arranged on routes where the conveying chains pass. The distance of each forme roller frame relative to one or more reference forme roller frames is preset, and the distance between each forme roller frame and each forme roller storage-taking opening and the direction are updated according to change of parameters of distances and directions output by the displacement sensors. By means of the system, digital storage, management and quick and automatic forme roller taking of forme rollers are achieved at the same time, and specified forme rollers can be taken out quickly. According to the system and the method, management procedures are simple, convenient and easy, failure rate is low, and the system and the method are suitable for popularization and use.

Description

technical field [0001] The invention relates to the access management of printing plate rollers in the printing industry, in particular to an access method for a large printing plate warehouse access system. Background technique [0002] Gravure printing has the advantages of high production efficiency, good hue stability, and thick ink layer, so many printed products use the gravure printing process. Since there are many kinds of gravure printing machines, there are differences in width and parameters between them. Therefore, after a set of gravure plate rollers is produced, only one type can be used, and multiple gravure printing machines can be used to print the same For printed matter, it is necessary to make multiple sets of gravure rolls to match the corresponding gravure models; since gravure rolls are generally supplied by multiple suppliers, each supplier has different processes for producing plate rolls, and multiple The supplier supplies the plate roll of the sam...

AI Technical Summary

Problems solved by technology

[0003] In many existing printing workshops with insufficient management, the gravure rolls are randomly stacked, resulting in chaos in the storage of the plate rolls, inconvenient search and access of the plate rolls, and scratches on the roll surface of the plate rolls if you are not careful. Affect the quality of printed products

Once a wrong gravure plate is printed on the machine, it will delay production, cause unnecessary waste of materials and construction time, and increase the cost of the printing factory

[0004] There are also some printing workshops equipped with simple plate roll storage racks, but they lack automatic control devices and are only used for storing gravure plate rolls. Roller storage racks are generally not highly integrated, occupy a large amount of space, and have high space requirements for printing plate storage places
