[0003] Existing palletizing devices are all fixed in one area and need to be manually transported to a nearby area for palletizing. When the distance between the transport site and the palletizing site is too far, the operator needs to move the clamping device back and forth to work, which greatly affects the work effect. In addition, the palletizing device can only palletize in one direction at a time. When changing the working direction, the direction of the device needs to be turned, which is very troublesome.
