Description

Technical Field

[0001] The utility model relates to the field of palletizers, in particular to an automatic palletizing device. Background Art

[0002] With the development of science, automated machinery has gradually replaced manual labor in various fields. Among them, there are relatively mature machines for conveying and stacking of cut sheets.

[0003] However, the disadvantages of this type of equipment are relatively significant. The problems include the low integration of the stacking device. The implementation of stacking generally includes the support of materials and short-distance transportation, material grabbing, carrying and grabbing material displacement, and placement of the grabbed objects. The stacking devices in the prior art are often relatively simple in functionality, and the intermediate links often involve manual participation, which affects the construction efficiency, and the safety is also uneven. Secondly, the current stacking device has a problem of unstable movement stroke in the material grabbing and subsequent work sections. The transportation based on the plate generally relies on electric suction cups, that is, adsorption-type grabbing, and the stability of its stroke directly affects the transportation safety of the plate. The second is that the mechanical mechanism is generally unreasonable. The stacking action involves lifting and lowering actions in the walking unit. At present, the implementation of this action generally relies on electric, pneumatic or hydraulic push rod mechanisms. It is inevitable that setbacks will occur at the starting and end points of the stroke, which is also not conducive to controlling the operation safety of the overall equipment.
