Anti-interference cigarette appearance quality online detection device and method

Abstract

The invention relates to an anti-interference cigarette appearance quality online detection device and method. In terms of the anti-interference cigarette appearance quality online detection device, afirst detection module is mounted on the side surface of a first conveying drum wheel, the first detection module is used for shooting two or more than two photos of one side surface of the same cigarette at different positions, two or more than two photos have an overlapping area, a second detection module is arranged on the side surface of a second conveying drum wheel, the second detection module is used for shooting two or more than two photos of the other side surface of the same cigarette at different positions, and the two or more than two photos have the overlapping area; the detection device further comprises an air blowing device, the air blowing device comprises an air outlet and a ventilation pipeline, and the ventilation pipeline is connected into a cavity where the detectionmodule is installed. The detection device has the beneficial effects that the detection device not only can identify the interference of droplets and sundries, but also can effectively remove defective cigarettes.

Description

technical field [0001] The invention relates to the field of on-line detection of cigarettes, in particular to an anti-interference on-line detection device and method for the appearance quality of cigarettes. Background technique [0002] In the process of modern cigarette production, the production speed is getting faster and faster, and the requirements of enterprises on product quality are becoming more and more strict. Among them, due to machine failure, cigarettes are prone to stains, cigarette paper damage, tobacco stems piercing, poor splicing, no printing, printing position offset, printing ink pollution and other undesirable products. Before machine vision inspection technology was used to detect the appearance of cigarettes, the appearance quality of cigarettes could only be observed manually, and mainly by random inspection. Due to the high production speed of cigarette making machines, it is impossible for humans to find and solve problems in time , causing rel...

AI Technical Summary

Problems solved by technology

The working method of manual random inspection of product quality is also an initial quality inspection method, which is a waste of manpower and material resources, and cannot guarantee that the product quality is fully inspected. The product quality and economic benefits of the enterprise cannot be well guaranteed, and the market competitiveness of the enterprise's products is constrained.

[0003] Based on the development of machine vision technology, some people thought of using cameras to take pictures to judge whether the appearance of cigarettes is defective, so as to replace the technical problem of low efficiency of manual inspection, but the following problems have always existed: 1) When the lens of the camera is attached to debris, then All cigarettes will be identified as defective ones, and all cigarettes will be removed. Driven by the high-speed rotating drum, there will be a lot of droplets and debris, which will be unavoidable; 2) There are inevitably droplets between the camera lens and the cigarette, and the camera will regard the droplets as a defect in the cigarette, thereby rejecting the normal cigarette

Therefore, for a long time, tobacco factories and equipment suppliers have always had a technical prejudice, that is, using cameras to detect the appearance defects of cigarettes online cannot be actually used in cigarette rolling machines, and has been unable to overcome the problem of high false rejection rate
