A system and method for feeding tobacco leaves

Abstract

The invention relates to the technical field of tobacco leaf processing, in particular to a tobacco leaf feeding system and method, comprising: a silo, wherein a controllable bottom plate is arranged in the silo, on which the tobacco leaves are placed; a laser projection lamp, the laser projection lamp is arranged in a The top of the silo projects a laser projection pattern to the top of the silo at a preset angle; the image sensor is used to collect the top view image of the silo; the suction device is used to suck and move the tobacco leaves to the processing equipment; the controller is used for according to the The top view image calculates the attitude of the tobacco leaves, controls the bottom plate to adjust the height and / or angle, and controls the suction device for suction. The beneficial effect of the present invention is that: by setting the laser projection lamp and the image sensor, the height and the inclination of the current uppermost layer of tobacco leaves can be calculated more accurately, and by setting the bottom plate with adjustable height and angle, it is possible to adjust the height and angle of the tobacco leaves when grabbing. The compensation of the height and the inclination angle of the tobacco leaves avoids the problems of insufficient height of the tobacco leaves or the existence of inclination angles in the prior art, which leads to the failure of grabbing.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf processing, in particular to a tobacco leaf feeding system and method. Background technique [0002] As an important economic crop, tobacco leaves have higher economic added value than grain. The quality of tobacco leaves determines its economic value. There is usually a big difference in the economic value of high-quality tobacco leaves and low-quality tobacco leaves. Therefore, when tobacco leaves are harvested, they often need to be graded. After the grading is completed, the corresponding processing procedures need to be carried out according to the different grades of the tobacco leaves, so as to form finished cigarettes of different prices to meet the market demand for products of different levels. Under normal circumstances, when the tobacco leaves are graded, they will be stacked in the silo according to the grade of the tobacco leaves. When the tobacco leaves need to be processed, ...

AI Technical Summary

Problems solved by technology

These phenomena have caused many difficulties for the grabbing and feeding of tobacco leaves.

For example, because the tobacco leaves are prone to curling after being roasted, the lower tobacco leaves are exposed, and other tobacco leaves are easily caught when grasping, causing the problem of unstable grasping of the tobacco leaves; when the tobacco leaves are offset, grasping may occur Not enough tobacco leaves, causing empty feeding problems; or because the tobacco leaves are tilted, the grasping is unstable, and the tobacco leaves fall during the movement, or even mixed into other grades of silos

These problems will directly lead to the failure of the tobacco leaf feeding process to meet the corresponding process requirements, thereby affecting the quality of finished cigarettes.
