[0002] In factory logistics transportation, a turnover vehicle is often used to transfer empty containers from a line operation to a storage area, and logistics personnel need to manually carry the containers one by one to the turnover vehicle, which is low in work efficiency and high in labor intensity. The existing technology uses mechanized turnover equipment to transfer stacked containers, such as the Chinese utility model patent with the application number CN201921461157.9 and the application name "Automatic unstacking and stacking equipment for turnover box conveying line". It includes a cabinet and a controller, and the top of the cabinet is provided with a driving motor. One pair of sides of the cabinet is respectively provided with a first passage and a second passage, and the first passage and the second passage are used as a passage for the turnover box conveying line.

The controller is connected with the driving motor to control the working state of the driving motor. The controller is also connected with a sensing device for detecting whether there is a container to be stacked on the turnover box conveying line in the cabinet.

[0003] The patent uses a mechanical arm above the turnover box to grab the turnover box, which realizes the stacking of different turnover boxes and increases the height of the entire production line. In addition, the mechanical arm also increases the cost of the entire turnover vehicle, so a small-size and low-cost stacking turnover vehicle is needed. UTILITY MODEL CONTENT
