Description

Technical Field

[0002] Currently, in the field of automated production equipment in the food industry, the market is dominated by two types of machines: tray loading machines and tray unloading machines. These machines have high operating costs and cannot automatically move baking trays from the conveyor line to the trolley or vice versa. Manual handling remains a significant need, hindering efficient continuous operation and preventing 24-hour uninterrupted operation. They are unsuitable for high-intensity, repetitive work scenarios. Furthermore, the lack of detection equipment during tray loading and unloading leads to inaccurate tray positioning, frequent misalignment or tipping, and a lack of integration with ovens, cooling lines, and packaging machines, resulting in incomplete production processes and long intervals between processes. Therefore, it is necessary to design a new tray loading and unloading device to solve these problems. Summary of the Invention
