Description

Technical Field

[0001] The utility model relates to the field of palletizers, in particular to a walking mechanism of an automatic palletizer. 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 biggest problem is that the movement of its traveling mechanism is not stable enough. The conveying of plates relies on electric suction cups, that is, adsorption-type grabbing. The stability of its travel directly affects the transportation safety of plates. The second is that the mechanical mechanism is generally unreasonable. The stacking action will involve lifting and lowering actions in the traveling 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 point and end point of the travel, which is also not conducive to controlling the operation safety of the overall equipment. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an automatic palletizer walking mechanism with a more reasonable structure, which can ensure the smooth operation of the walking mechanism itself and provide smooth travel support for the rise or fall of the plate grabbing mechanism.

[0005] The equipment includes a frame, which is the assembly base of the equipment;

[0006] The frame includes a frame top plate, on which a plate grabbing unit power mechanism is arranged; track running wheels with the same rotation direction are arranged at the four corners of the frame top plate;

[0007] The bottom of the frame top plate is provided with a frame bottom plate through multiple connecting rods, the frame bottom plate is a rectangular frame, and track tugs are provided at the four corners of the bottom plate;

[0008] Preferably, the rotation direction of the rail tug is consistent with that of the rail traveling wheel, and the distance between the rail tug and the rail traveling wheel is set corresponding to the rail height.

[0009] The effect achieved by this is that the track running wheel fits on the track surface, and the track tug fits on the bottom surface of the track, and the two form a full lock on the running track;

[0010] During implementation, the equipment is set on the track of the palletizer frame, and the frame part is driven by the synchronous belt to move, thereby achieving the effect of its lateral and stable displacement.

[0011] A lifting rail assembly pipe is inserted into the frame, and a locking wheel is arranged on the lifting rail assembly pipe.

[0012] The effect achieved by this is that, during implementation, a guide rail is passed through the lifting rail assembly tube, and the guide rail is fixedly connected to the plate grabbing unit;

[0013] The plate grabbing unit is connected to the power mechanism of the plate grabbing unit through a sling. When the power mechanism is started, the plate grabbing unit is lifted up, and the guide rail is restricted by the lifting rail assembly tube and the locking wheel, so that the lifting and lowering action of the plate grabbing unit is smooth and stable.

[0014] The beneficial effect of the utility model is that the utility model solves the problem of the stability of the walking unit before the stroke in the plate grabbing structure of the prior art. Through a simple structure, the frame part ensures the stability of its own lateral displacement stroke, and at the same time, through the lifting rail assembly tube, guide rail and locking wheel group, provides structural support for a smooth lifting stroke for the lifting of the plate grabbing unit.
