Description

[Technical field]

[0002] With the rapid development of the economy, the problem of insufficient storage space for goods in processing enterprises has become one of the problems that people urgently need to solve, and the use of stereoscopic warehouses has effectively alleviated the phenomenon of insufficient storage space for goods. The pallet stacker is one of the important tools for transferring and storing goods in stereoscopic warehouses. However, the existing pallet stacker only has the function of lifting the height and cannot provide real-time feedback on the height position of the goods. Therefore, it is difficult to adapt to the corresponding shelf height and can only be manually controlled and difficult to achieve automation. In view of this, we propose a pallet stacker structure solution that can automatically adapt to the shelf height. [Summary of the invention]
