Embodiment Construction

[0013] Referring to each figure, the foreign matter removal device used in the removal method of the present invention is mainly composed of four parts: a single-layer processing unit, a detection unit, a removal unit, and a material return unit. or tobacco stems) for identification, removal, and material recovery. The single-layer processing unit carries out material transportation and secondary acceleration to form a thin layer of high-speed tobacco leaves (or tobacco stems); the detection unit includes a CCD camera dot matrix and its image processing system, and integrates a high-illuminance, high-color rendering system lighting system, dot matrix The CCD camera captures the real-time image of the tobacco leaf, sends it to the digital processing unit, performs image processing, recognizes the sundries and calculates the position information of the sundries, controls the opening of the pneumatic solenoid valve, and sprays high-speed, high-pressure airflow from the nozzle to b...

Abstract

The invention relates to a method and a corresponding device for removing foreign bodies in tobacco manufacturing, in particular to a method and device for removing the tobacco foreign bodies based on vision and belongs to the device for removing the foreign bodies based on vision. The method and device are mainly suitable for the impurity removal process of various industrial processing. According to the method and device, firstly a tobacco material is conveyed while being vibrated so that the tobacco material can be dispersed and evenly distributed, then acceleration vibration conveying is conducted so that the material can be subjected to single-layer processing, then the tobacco material enters a constant-speed conveyor belt, real-time images of tobaccos are shot by lattice CCD cameras and transmitted to a digital processing unit for analyzing and processing of grayscale signals of the images, and the positions of the foreign bodies are confirmed; and corresponding solenoid valves on the positions at the time point are controlled to be opened, the conveyed material is laterally blown by compressed air, and the foreign bodies are blown off and fall into foreign body hoppers on the two sides of the belt. According to the method and device, intelligent automatic equipment which integrates light, machinery, electricity and gas is adopted for foreign body removal, foreign body removal is quite reliable, the working efficiency is high, and the percent of pass of cigarettes is increased greatly.

Description

technical field [0001] The invention relates to a method and a corresponding device for removing foreign matter in tobacco manufacturing, which are mainly applicable to the removing process of various industrial processes, and belong to a vision-based foreign matter removing device. Background technique [0002] In my country's tobacco manufacturing enterprises, with the improvement and upgrading of production technology, the degree of automation of production lines is getting higher and higher, and the requirements for product quality are also getting higher and higher. However, in the re-baking and silk-making production lines, there will be some sundries mixed in the tobacco leaves to varying degrees: metal sheets, plastics, paper, rubber, etc. These impurities mixed in the tobacco leaves will affect the quality of the cigarette. In particular, chicken feathers, plastics and other sundries that produce pungent odors after burning are especially concerned by cigarette fac...
