Paper product production quality intelligent inspection method and system

Abstract

The invention discloses a paper product production quality intelligent inspection method and a system, and the method comprises the steps: firstly calculating the impact degree values of all production quality evaluation indexes of a paper product on the technological performances of a paper product finished product, determining a core evaluation index according to the impact degree values, and determining a core production process corresponding to the core evaluation index; moving detection equipment to perform image acquisition on paper products produced in the core production process beforeentering a next production process, carrying out defect detection on the collected images, then moving the detection equipment to send defect detection information to a mobile quality control terminal, and finally adopting the mobile quality control terminal to analyze the received defect detection information; and regulating and controlling the production equipment of the corresponding production process. According to the method, on the premise of ensuring the process quality of paper products, the process processing capacity, the defect monitoring capacity and the equipment control capacityof a production line are balanced and optimized, and the limited defect monitoring capacity is applied to the most critical detection point.

Description

technical field [0001] This application relates to the technical field of automatic control, in particular to an intelligent inspection method and system for the production quality of paper products. Background technique [0002] The paper product processing industry is one of the important industries in our country. Whether it is corrugated cardboard for packaging boxes or paper towels as sanitary products, they are indispensable and common products in daily life. [0003] In the paper processing industry, in order to ensure the processing quality of paper products, it is necessary to monitor the quality of intermediate products or finished products produced by each processing process. With the increasing demand for quality and function of paper products in society, paper products The processing technology becomes more and more complex, so that paper products with multiple functions (such as pressure resistance, moisture resistance, etc.) can be produced, which also leads t...

Problems solved by technology

[0003] In the paper processing industry, in order to ensure the processing quality of paper products, it is necessary to monitor the quality of intermediate products or finished products produced by each processing process. With the increasing demand for quality and function of paper products in society, paper products The processing technology becomes more and more complex, so that paper products with multiple functions (such as pressure resistance, moisture resistance, etc.) can be produced, which also leads to an increase in processing procedures; at the same time, due to the increasing functional requirements of paper products, the types of paper products Therefore, the same production line needs to have the ability to process multiple types of paper products, which also leads to an increase in the number of processes on the production line and the increase in production equipment

[0004] Under the above circumstances, the current way to ensure the quality of processing is to rely on the experience of operators to check and inspect the quality of paper products in each process, and even for production lines with advanced quality inspection capabilities, the method used is also Quality inspection equipment is installed in all process links for quality inspection, which leads to an increase in the cost of quality inspection, and the current inspection method of quality inspection equipment is to inspect the process parameters of production equipment, and because there are many types of process parameters , and also mixed with various unpredictable interference factors (such as environmental factors), which makes the working conditions extremely complicated, and the real consequences caused by the influence of process parameter fluctuations are difficult to judge, and it is impossible to simply think that a certain parameter has increased It will lead to corresponding defects in paper products, because the fluctuation of other parameters and the influence of environmental factors, equipment factors, human factors and errors need to be considered, so this detection method is complicated and cannot guarantee the accuracy of quality detection results

[0005] Therefore, the increase of the above-mentioned detection cost and the accuracy of the detection results are problems that need to be solved urgently
