Description

Repeated detection and removal device of cigarette strip vision

Technical Field

The utility model belongs to the technical field of the electric automated inspection of tobacco, specifically speaking relates to a repeated detection removing devices of cigarette strip vision.

Background

The existing visual appearance detection device for the cigarette sticks is used for shooting and detecting a plurality of surfaces or parts of the cigarette sticks by a plurality of cameras, but for each surface or part of the cigarette sticks, one camera is used for shooting one surface or part of the cigarette stick once, taking one image, processing one image and analyzing the image to obtain whether the surface or part is qualified. For a detection surface or part of the cigarette strip, information obtained by one image is too little, and when various interferences, errors, partial unclear images and the like occur in the processes of shooting, transmission, processing and the like of the images, the detection result is inaccurate and unreliable.

A camera is used for shooting one surface or part of the cigarette rod, processing and analyzing an image and a primary image, the obtained image and information are limited, the detection algorithm is limited, the detection result obtained in many times cannot determine whether the cigarette rod is qualified, and the qualified or unqualified result is provided finally.

For example: the characteristics of the transparent pull line, the transparent packaging paper, certain trademark printing and the like have certain invisibility, and the images at certain angles show unclear or no display, which is difficult to detect, but can be clear after the angles are changed. Even if the shooting angle is selected and compared during design, installation and debugging, the cigarette sticks can irregularly jump due to the vibration, the unevenness and the like of the conveying belt; random deformation can occur to the drawing line, the transparent packaging paper, the trademark paper and the like, most of deformation sizes are within an allowable range, but the variation range of shooting angles of the drawing line is large, and invisible features to be detected are unclear or not clear in an acquired image frequently. For reliable product quality, only the tobacco strips can be removed, so that a high false removal rate is caused, and otherwise, if the detection precision is reduced for reducing the false removal rate, unqualified products cannot be reliably detected and removed.
