Coding system

Abstract

The invention discloses a coding system, which includes: a horizontal positioning device, used to identify the horizontal marking information of paper, and generate coding horizontal position data according to the horizontal marking information; a vertical positioning device, used to identify the The longitudinal marking information of the paper, generating the longitudinal position data of the inkjet code according to the longitudinal marking information; the quality detection device, used to detect the quality of the paper, and generating the quality detection data of the paper; the inkjet printing device, used in the The position of the paper corresponding to the coding horizontal position data and the coding vertical position information data, and the identification code corresponding to the quality inspection data is printed. Therefore, the inkjet coding system of the present invention can detect the quality of the paper, and then print the quality identification code on the position where the paper should be printed according to the specific situation, thereby realizing convenient and effective marking, and improving the production quality and quality of the paper. management level.

Description

technical field [0001] The invention relates to a coding system for communication, in particular to a coding system for printing quality identification codes and information identification codes. Background technique [0002] In the copying of ordinary paper, the single paper cannot be separated before the paper is cut into single sheets, and the number of sheets does not matter, so it is impossible to track and manage the single sheets during the paper machine copying process, and For some special anti-counterfeiting papers (such as banknote paper, valuable certificate paper, high-grade anti-counterfeiting civil paper, etc.), the individual sheets can be distinguished, so the paper information of the individual sheets during the copying process can be tracked manage. [0003] However, in the production process of these special anti-counterfeit papers, it is difficult to mark and even more difficult to remove when paper defects are found. For example, the existing quality c...

Problems solved by technology

[0003] However, in the production process of these special anti-counterfeiting papers, it is difficult to mark and even more difficult to remove when paper defects are found. For example, the existing quality control system (Quality Control System, QCS) detects problematic paper Unable to mark; the laser punching mark of the CCD online detection system is too small and too narrow, difficult to find, inconvenient to identify, and can only be manually identified and removed; in addition, it is impossible to accurately manage the single sheet of paper in the production process; As far as the factory is concerned, it is not convenient to give feedback because there is no mark when giving paper quality feedback

[0004] Therefore, the existing system cannot carry out convenient and effective marking according to the specific conditions of the paper
