Process and system for automatically cleaning tobacco boxes

Abstract

The invention relates to a process and a system for automatically cleaning tobacco boxes. The process comprises the following steps of: conveying the tobacco boxes to a cleaning system, detecting the bottom of the boxes by a visual detector (5) to judge whether the tobacco boxes need cleaning or not, and identifying the positions of residual materials in the boxes; directly sending the tobacco boxes not needing cleaning out of the cleaning system, and conveying the tobacco boxes needing cleaning to a tobacco box turning station; turning the tobacco boxes by 90 to 150 DEG by a tilter (6) so that openings face a cleaning robot (7); stretching a cleaning claw (7c-2) of the cleaning robot (7) into the boxes for cleaning, cleaning the residual materials to a residual material belt conveyor (8), and then conveying the residual materials to a recycling box (9); turning and resetting the cleaned tobacco boxes by the tilter, and sending the tobacco boxes back to a visual detector station for rechecking; and sending the tobacco boxes qualified in the rechecking out of the cleaning system, and conveying unqualified tobacco boxes to the tilting station again for secondary cleaning or directly conveying the unqualified tobacco boxes to a manual cleaning station for cleaning. The process and the system can complete automatic cleaning of the tobacco boxes for storing shredded leaves and sliced leaves.

Description

technical field [0001] The invention relates to the technical field of a process and system for detecting residual materials inside a storage box of tobacco leaves or shredded leaves and automatically cleaning them. Background technique [0002] In order to ensure the cleanliness of the inside of the box in the tobacco industry, it is necessary to clean the inside of the box after use or before use. Due to the large volume of the box, manual cleaning is required. It is more complicated, labor-intensive and has artificial unsafe factors. Therefore need a kind of system that can automatically clean the inside of the casing. In order to improve production efficiency and production quality, avoid repeated cleaning of clean boxes, or ensure that the cleaned boxes are clean, it is also necessary to test the cleanliness of the boxes. In addition, the materials stored in the box may be of different brands. When cleaning and recycling, it is necessary to classify and recycle the re...

Problems solved by technology

[0003] At present, for the large-scale boxes that store tobacco leaves, tobacco sheets and other materials, the internal cleaning method is mainly manual cleaning. Although some auxiliary tools, such as vacuum cleaners, are also used during cleaning, they are all based on manual cleaning. High labor intensity, it is difficult to realize automatic operation

In response to this deficiency, some industries currently use industrial robots to complete the automatic cleaning inside the box, but the robots used are generally multi-joint general-purpose robots, which have high investment costs, complex technologies, and low work efficiency.

Moreover, the function of the cleaning tool is too simple, mainly to install a brush or a brush roller on the end claw of the robot. During use, it is inevitable that the brush will shed hair. In some industries with food-grade cleanliness requirements Not available

In addition, these devices lack an effective residual material detection device, and cannot effectively detect the cleanliness inside the box. They can only clean all the boxes, which reduces the working efficiency of the system. At the same time, it is impossible to clean the cleaned boxes. Re-inspection, it is difficult to reliably ensure that the bins that have been cleaned and put back into service are clean

In addition, the existing cleaning system does not have the function of automatic classification and recycling of residual materials, which limits the effective recycling of residual materials
