Description

Technical Field

[0001] The utility model relates to the technical field of palletizers, in particular to a double-column cantilever palletizer. Background Art

[0002] Palletizer is a device that automatically stacks bags, cartons or other packaging materials transported by conveyor into stacks according to the working method required by the customer's process, and transports the stacked materials. In the work of double-column palletizer, it can play a good supporting role for heavy objects during palletizing. However, the existing double-column palletizers generally have the following technical problems:

[0003] The double columns of the double-column palletizer play the main supporting role of gravity in the vertical direction. The double columns are mainly used for lifting objects in the up and down directions, and the movement of the lifting objects in the front and back directions is often achieved by designing a cantilever frame that moves up and down along the double columns. The cantilever frame moves forward and backward to drive the displacement adjustment in the front and back directions. However, when the cantilever frame lifts objects in the up and down directions, the cantilever frame needs to move as a whole relative to the double columns. This method has no problem for the short-term operation of the palletizer, but in the long run, it has great problems. There are many disadvantages. First, after the heavy objects are directly hoisted under the cantilever beam frame, the cantilever beam frame and the double columns are vertically lifted and lowered at 90 degrees. In this way, the gravity under the cantilever beam frame will increase the shear resistance problem at the intersection of the double columns and the cantilever beam frame. Because the cantilever beam frame moves on the double columns instead of being fixedly connected, long-term operation will increase the wear of the intersection of the double columns and the cantilever beam frame. On the one hand, it will reduce the distance conveying accuracy of the palletizer. On the other hand, the overall structural stability of the frame system composed of the double columns and the cantilever beam frame on the palletizer will be unbalanced.

[0004] Based on this, a double-column cantilever palletizer is proposed. Utility Model Content
