Paper extraction mechanism with high-accuracy single-piece adsorption function, and control method thereof

Abstract

The invention discloses a paper extraction mechanism with a high-accuracy single-piece adsorption function. The paper extraction mechanism with the high-accuracy single-piece adsorption function comprises a tray, a motor, a controller, a vacuumizer, a vacuum electromagnetic valve, a vacuum flow distributor, a vacuum adsorption disc, a paper movement device, a vacuum pressure sensor, an air compressor, a compressed air flow distributor, a blowing head, a proximity switch and a microswitch, wherein the components are combined into an automatic system. The invention further discloses a control method of the paper extraction mechanism, wherein high-accuracy adsorption for a single piece of paper is realized. According to the paper extraction mechanism with the high-accuracy single-piece adsorption function, and the control method thereof, adsorption of the vacuum adsorption disc for a single piece of paper in one process can be guaranteed, so that the problem of adsorbing two pieces of paper or a plurality of pieces of paper is avoided, and the control accuracy and working efficiency of paper extraction are increased; and moreover, the invariable uppermost position of a paper pile is guaranteed, so that the automation level of the field of paper extraction and conveying is further increased. The paper extraction mechanism with the high-accuracy single-piece adsorption function, andthe control method thereof are especially applicable to extraction working for thin paper with the size of 40g / m<2>-100g / m<2>.

Description

technical field [0001] The invention relates to a paper extracting mechanism, in particular to a paper extracting mechanism with a high-precision single-sheet adsorption function and a control method thereof. Background technique [0002] The paper conveying mechanism is used in industrial production to extract the paper from the paper pile and then send it to the standby position. For example, in the production process of the packaging box, the face paper needs to be sent to the box body for pasting. [0003] The paper extraction mechanism is an important part of the paper conveying mechanism. How to quickly, non-destructively and single-sheet extract paper and realize automatic control is an important problem to be solved in paper conveying, so the performance of the paper extracting mechanism is very critical. [0004] The traditional paper extraction mechanism mostly adopts the vacuum adsorption method, which can realize rapid and non-destructive extraction of paper and ...

Problems solved by technology

[0006] However, when the above-mentioned printing paper layered extracting device extracts thin papers with low weight, due to the certain natural suction between adjacent two or more thin papers and the suction effect of the suction cup, it is easy to suck double or multiple sheets. Thin paper phenomenon requires human intervention and reduces work efficiency
