Abstract

The invention discloses a method for automatically sorting and classifying paper, and belongs to a quality detection and sorting method of a paper making process. The purpose is to provide the method that paper is decomposed into a single piece of paper to detect the appearance quality, and the single piece of detected paper is classified and respectively counted by adopting a linking automatic equipment, and then sorted the ream output or the quire output. The method mainly comprises the following steps: quires of flat paper are outputted by utilizing a paper conveying machine in the form of a single piece of flat paper; at the outlet end of the paper conveying machine, the appearance quality of the paper is detected by utilizing a computer visual processing system; the appearance quality of the paper is detected by utilizing a computer visual processing system; the paper is counted and selected; the ream and the quire are sorted to qualified paper; reams or quires of paper are outputted. The invention can be suitable for the quality detection and the sorting and the classifying of various pieces of paper in the paper making production.

Description

technical field [0001] The invention belongs to a quality detection and sorting method of a papermaking process, in particular to a method for automatic sorting of paper products. Background technique [0002] In the current domestic papermaking process of the paper industry, especially in the production process of banknote paper, it is not possible to realize the production of flat paper into single sheets, and then carry out the quality inspection of individual sheets, and then automatically sort and sort according to the test results. . [0003] Domestic banknote paper factories mainly rely on manual counting and delineation, and rely on imported counting machines to count and confirm the addition and deletion of paper. [0004] Some manufacturers in foreign countries, including my country, use paper machine laser online inspection system to inspect the appearance quality of paper products, but in terms of its effect, the inspection ability cannot eliminate Class A and C...
