Research on Cigarette Shape Detection based on Dual Channel Acquisition

Abstract

The cigarette shape detection system of cigarette machine is to online detect the unqualified cigarettes with warping, paper sticking, flattening and mouth burst in the high-speed flow cigarettes on the production line, and eliminate them in real time to ensure the product quality of finished cigarettes. At present, the photoelectric technology is adopted for the cigarette shape detection sensor, and the output signal range is analog quantity within 0-15Vdc. According to the field installation error, sensor difference and attenuation in use, the front and rear signal ranges are inconsistent. Corresponding modules are required to adjust the reference voltage and magnification of the front and rear channels and output standard 0-10vdc analog quantity. The current module is installed under the max detection wheel and adjusted through the general potentiometer of the internal circuit board. It is independent of the quality detection system and is far away from the MLP man-machine interface of the quality data display. Therefore, the adjustment process is very inconvenient, the device improves the calibration intelligent level of this part, forms a closed loop with the quality detection system, improves the adjustment accuracy, prolongs the service life, improves the staff work efficiency and facilitates the staff operation.
