Description

Automatic unloading system

technical field

The utility model relates to an unloading device, in particular to an automatic unloading system, which belongs to the technical field of automatic unloading equipment.

Background technique

At present, feed, grain, oil, food and other industries often use woven bags to package materials. After packaging, they are often transported by trucks. The packaging bags are stacked in the carriage in multiple layers. When they arrive at the unloading point, if they are transported bag by bag, the workload is too large. In order to reduce the labor intensity of workers, forklifts or other automated equipment are used to assist unloading in many occasions. Usually, multiple bags are stacked on the pallet. Usually, four to six bags can be stacked on each layer of the pallet, and multiple layers can be stacked up and down. , so that several packaging bags can be transferred at a time, which greatly improves the work efficiency.

After the packaging bags on the pallet are finished, the empty pallet needs to be returned to the unloading station to be put into use again. Usually, workers are stacked one by one on the shovel arm of the forklift truck. After stacking multiple pieces, they are transported back to the unloading station by the forklift truck. This method of operation has high labor intensity and low degree of automation.
