Abstract
Description
Technical Field
[0001] The utility model relates to the field of cigarette making equipment, and more particularly to a cigarette box self-positioning system. Background Art
[0002] The carton unpacking machine is a special equipment developed to support the automation of tobacco production logistics. Compared with other similar equipment, it has the characteristics of small footprint, low power consumption, simple operation, and high success rate of unpacking. It can flexibly realize the rational layout of the tobacco factory's tobacco production process, improve production efficiency, reduce workers' labor intensity, and improve the working environment. It has become a key equipment connecting the raw tobacco leaf formula library with tobacco production and has been widely used in domestic cigarette factories.
[0003] Before cigarette cases enter the pack opening (unpacking) machine for case turnover, a manually operated lifting vehicle places the cigarette cases on a roller conveyor and sends them to the case turnover machine. Since it is difficult for manually operated lifting vehicles to hold cigarette cases, it is difficult to accurately place the cigarette cases on the roller conveyor in a horizontal position. This mainly causes the following problems:
[0004] 1. The crooked cigarette boxes often get stuck in the rolling track of the box turning machine during the process of moving, and cannot enter the turning process, causing the equipment to stop;
[0005] 2. When placing the cigarette boxes on the truck, they often fall directly onto the sides of the roller conveyor, causing damage to the equipment;
[0006] 3. The tilted cigarette box is stuck between the two sides of the roller conveyor, causing damage to the cigarette box. When the box is opened, a large amount of tobacco leaves will fall out and the amount of tobacco leaves will increase.
[0007] 4. The crooked cigarette box is stuck in the roller of the carton turning machine and needs to be manually straightened before entering the next process. The cigarette box currently used in our factory weighs 200kg. The cigarette box stuck in the roller of the carton turning machine, due to its own weight and the friction of the roller, generally requires at least two operators to push the cigarette box, which is time-consuming and labor-intensive, and creates unsafe factors.
