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

Embodiment Construction

[0025] The present invention is combined as follows figure 2 The working principle and process will be further explained:

[0026] attached figure 2 This is the cigar wrapper raw material pretreatment process of the present invention. The cigar wrapper raw material is subjected to moisture rejuvenation and industrial fermentation treatment. Collect the tobacco leaf images on the belt in real time; the image processing unit analyzes the outline and size of the tobacco leaves and the position of the veins in the middle of the tobacco leaves in real time. According to the principle of the highest utilization efficiency of cutting the wrapper from the tobacco raw material, the image processing unit optimizes and determines the cutting quantity and cutting path of the wrapper on the tobacco leaf; at the same time, for each target cutting area, extract and analyze its color information and Defect information, classify and identify the quality of the wrapper; the servo motor of t...

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...
