Background

The unstacker belongs to one of more important devices in the packaging machinery industry, and is mainly used for splitting an empty glass bottle stack or a pop can stack so as to facilitate the cleaning and filling operation of a rear section; glass bottles and pop-top cans required by most beverage enterprises are generally purchased from outsourcing, and rarely produced by themselves; the distance between a can making plant or a bottle making plant and a beverage enterprise is far, the bottle stacks or the can stacks need to be transported for a long distance, and the bottle stacks or the can stacks are easy to incline and move in the transportation process and the loading and unloading process; in addition, the appearance countries of the glass bottles have no unified requirement, the shapes are different, a plurality of bottle types adopt the appearance design with big heads and small bottoms for the purpose of attractive design, the appearance is attractive, but the stability is poor, the bottles are easy to fall, and the unstacking process is easier to fall and damage.

The traditional unstacking method is characterized in that a bottle pushing mechanism is matched with a hydraulic lifting platform, single-layer cans or glass bottles are pushed to a chain network cable, then single-row output is formed by a turntable sorting platform, and finally the single-row output enters a bottle washing machine; however, as the pit is required to be dug when the hydraulic lifting platform is installed, the use environment of the hydraulic lifting platform is limited by floors, and when a bottle falls, the hydraulic lifting platform is not easy to clean and the hydraulic pressure in the pit is not easy to maintain; in addition, the appearance factors of a plurality of glass bottles are not considered during design, so that the bottles are seriously turned during unstacking, and the cost is wasted for a plurality of beverage enterprises.
