Description

Technical Field

[0001] The present application relates to the field of packaging box palletizing, and in particular to a packaging box palletizing device. Background Art

[0002] A packaging box refers to a box or container used to package, protect and transport goods. After the items are packaged, the packaging boxes are generally stacked and placed, that is, a certain number of packaging boxes are stacked up and down on a pallet to keep the stacked packaging boxes in a neat state as a whole. They are then moved manually or by forklifts. Existing palletizing devices are generally operated by robots or mechanical arms, which sense the placement of the packaging boxes through sensors and grab the packaging boxes by adsorbing the upper surface of the packaging boxes with suction cups.

[0003] Since the sizes of packaging boxes required for different items are different, and the adsorption range of the suction cup at the end of the robot arm is generally in the middle of the upper surface of the packaging box, when the packaging box is larger as a whole, the suction cup may be unstable when adsorbing on the upper surface of the packaging box due to the small adsorption range, causing the adsorbed packaging box to shake as the robot arm moves during stacking, reducing the stability of the suction cup when adsorbing the packaging box, and posing certain safety hazards when stacking the packaging boxes.

[0004] With respect to the above-mentioned related technologies, the inventor believes that the robot arm has a defect of limited suction range of the suction cup when adsorbing and stacking packaging boxes. Therefore, a packaging box stacking device is proposed to solve the above-mentioned problem. Utility Model Content
