Design and Application of Cigarette Maker’s Online Inspection System for Cigarette Appearance

Abstract

In order to solve the problem that the continuous appearance inspection of the online product of the single-piece can not be carried out during the process, the online appearance inspection system of the cigarette-making unit was designed according to the running characteristics of the machine. The device is mainly composed of a camera control unit, a light source control unit, a signal processing unit and a data communication unit. The system first obtains the cigarette machine production status and single cigarette segmentation signals of continuous cigarettes through an axis encoder. The light source control unit and camera control unit work together to obtain images of a single cigarette at different stations, and perform realtime calculation and integration through the signal processing unit. After the shaft encoder, the processed signal is aligned with the cigarette, and finally the rejection is performed through the rejection valve. The ZJ17 rolling unit and cigarette products with a diameter of 5.4mm, a total length of 84mm, a cigarette length of 54mm, and a filter length of 30mm were tested. The results showed that the online appearance inspection system of the cigarette unit of the rolling unit had a detection accuracy rate of ⩾ 98%, missed rejection rate ⩽ 2%, false rejection rate ⩽ 2%. The device realizes the continuous detection of the appearance of the single product of the spliced product online, and opens up new ideas for the quality assurance of the appearance of the spliced product.
