Description

Technical Field

[0001] The utility model relates to the technical field of ampoule bottle production, in particular to a pallet unloader. Background Art

[0002] In the production and transportation process of ampoules, pallet unloading is a crucial link. The traditional method of unloading ampoule pallets mainly relies on manual operation, that is, workers manually remove the pallets on the sterilization vehicle one by one and then place them in the designated location. However, this manual unloading method has many shortcomings. First, manual unloading is inefficient and cannot meet the needs of large-scale production. With the expansion of the production scale of ampoules, the number of pallets on the sterilization vehicle continues to increase. Manual unloading requires a lot of time and manpower, which seriously restricts the improvement of production efficiency. Secondly, manual unloading has safety hazards. During the unloading process, workers need to frequently bend over, lift and other actions, which can easily cause physical fatigue and injury. At the same time, since the ampoules themselves are relatively fragile, improper manual operation can easily lead to damage to the ampoules, resulting in product losses and safety hazards. In addition, with the continuous improvement of industrial automation and intelligence, more and more companies are beginning to seek automated and intelligent solutions to replace traditional manual operations. In the field of ampoule pallet unloading, although there are some automated unloading equipment, most of them have problems such as complex structure, cumbersome operation and high cost, making it difficult to be widely used.

[0003] Therefore, in response to the above problems, this patent proposes a new type of pallet unloading machine, which aims to achieve efficient and safe unloading of ampoule bottle pallets in an automated and intelligent way. The equipment adopts a liftable unloading conveyor and a tray pushing mechanism to cooperate with each other, which can automatically unload the multi-layer ampoule bottle pallets in the sterilization vehicle one by one and transport them to the designated location, greatly improving the unloading efficiency and safety, and reducing labor costs and product losses. At the same time, the equipment has a simple structure, easy operation, and low cost, and has broad application prospects and market demand. Utility Model Content
