Problems solved by technology

There are two disadvantages in this method: firstly, the data of the entire batch of removed materials is only the total data, and the results of manual sampling and visual inspection are completely based on the operator’s experience, and there is no accurate component composition data. The content is unknown, and there is a lack of data basis for lean management; secondly, manual sampling requires on-site operators to sample regularly, which increases the workload

Embodiment Construction

[0020] Such as figure 1 , Tobacco shredded air selection and stalk quality online inspection system includes material thinning machine 1, camera 2, light source 3, mounting bracket 4, electrical control box 5, processor 6.

[0021] The material thinning machine 1 is used for thinning the mixture of stems and shredded tobacco to a certain extent. The camera 2 and the light source 3 are fixed on the mounting bracket 4, the camera 3 is used to capture images, and the light source 3 is used to ensure the light intensity required for image quality. The electrical control device 5 is used for logical control such as starting and stopping of the material thinning machine 1 with the material entering, camera 2 taking pictures or recording, and light source 3 turning on or off. The processor 6 processes the image information, calculates and outputs the weight ratio of the stem stick and shredded tobacco.

[0022] Combine below figure 2 Explain the detection principle of the system:...

Abstract

The invention discloses an online detection method and system for winnowing stem-picking quality in tobacco primary processing production, the system comprises a camera which obtains an image of a mixture of picked stem slivers and tobacco shreds after winnowing; and a processor which analyzes to obtain the area proportion of the sliver and the tobacco shreds on the surface of the material, and calculates and outputs the weight proportion of the sliver and the tobacco shreds in combination with the surface density ratio data of the sliver and the tobacco shreds. Online automatic real-time detection of stem picking quality is realized, weight proportion data of stem slivers and tobacco shreds in the picked object can be outputted in real time, and a real-time basis is provided for adjustment of the winnowing effect; meanwhile, the dependence of winnowing equipment operation and effect judgment on operators is reduced, the intelligent operation degree of a production line can be improved, and the labor intensity is reduced.

Description

technical field [0001] The invention relates to quality detection of winnowing and stalk picking in tobacco shred production. Background technique [0002] In tobacco shred processing, it is necessary to use flexible winnowing equipment to separate the stems in shredded tobacco online. The separated stem stick generally contains a certain amount of shredded tobacco, and this part of shredded tobacco is directly discarded. Removing the shredded tobacco content in the stem will directly affect the shred yield and material cost of shredded production. At present, most of the silk-making lines control the total amount of the removed stems, and the cut tobacco content in the removed stems is mainly controlled by the production personnel to conduct sampling and visual inspection during production, and adjust the effect of flexible winnowing according to the sampling results. There are two disadvantages in this method: firstly, the data of the entire batch of removed materials is...
