Cigar coating raw material pretreatment process based on machine vision

Abstract

A cigar wrapper raw material pretreatment process based on machine vision comprises the steps that tobacco leaf raw materials for making cigar wrappers are subjected to moisture regaining treatment and industrial fermentation, then scattered and spread to a detection belt and then enter an optical detection unit; the unit collects tobacco leaf images in real time, and determines an optimized cigar coat cutting path through tobacco leaf vein position, tobacco leaf size and leaf surface defect characteristic detection; then the tobacco leaves are conveyed to a cutting station, the cutting station receives cutting path information sent by the optical detection unit in real time, a servo motor drives a cutting tool bit to cut the tobacco leaves, and cut eggplant coats are sorted through a mechanical sorting device; and the remaining tailings are fed into a bypass threshing procedure to be treated. According to the process, a machine vision method is adopted for carrying out tobacco appearance detection, cigar wrapper cutting and cigar wrapper classification on tobacco raw materials for manufacturing cigar wrappers, manual operation procedures such as manual stem extraction, manual skin arrangement and manual cutting in an existing pretreatment process are avoided, the cigar wrapper pretreatment processing efficiency can be effectively improved, and the utilization efficiency of the tobacco raw materials is improved.

Description

technical field [0001] The invention relates to the field of tobacco technology, in particular to a machine vision-based pretreatment process for cigar wrappers. Background technique [0002] Cigars are a special kind of tobacco products. Traditional cigars usually refer to full-leaf hand-rolled cigars, that is, the three parts that make up a cigar—the filler, the wrapper and the wrapper are all made from tobacco leaves, and the entire production process is all done by hand. . In addition to the internal quality, high-quality whole-leaf rolled handmade cigars also have very high requirements on the appearance quality, such as smooth appearance, uniform color, no damage, wormholes and disease spots, standard shape, complete structure, etc. [0003] The appearance quality requirements of cigar products are closely related to the quality of their wrappers, especially the pretreatment process of the wrapper tobacco leaves. Tobacco leaf pretreatment before cigar rolling is also...

AI Technical Summary

Problems solved by technology

This pretreatment process has problems such as many manual pretreatment steps, long process flow, and low processing efficiency. At the same time, in the process of manually classifying and cutting wrapper raw materials, there are also inconsistent subjective judgments in the classification process, and the raw material utilization rate in the tobacco leaf cutting process is not high. , wrapper tobacco leaf raw materials are often cut into the tailings treatment, it is difficult to achieve high-value utilization of tobacco leaf resources
