Description

Background technique

Cable racks are devices used to support cables, usually made of metal materials, with high strength and stability, and are mainly used for indoor and outdoor cable installation; cable racks are usually installed on walls, ceilings, and floors, and used with other devices such as cable troughs, steel structures, cable trays, etc. There are many types of cable racks, including hanging, wall-mounted, ground-mounted, etc., which can be selected for use according to actual needs. When cable racks need to be transported or stored and the quantity is large, in order to facilitate handling and storage, the cable racks will be stacked and stored.

Conventional palletizing equipment is mostly a mechanical gripper mechanism. Palletizing equipment with a mechanical gripper structure mostly adopts a falling placement operation from top to bottom when palletizing cable racks. Due to the irregularity of the cable racks, traditional mechanical grippers are likely to cause the cable racks to flip and swing when clamping them, which is likely to cause damage to some high-precision cable racks, thereby increasing the transportation loss of the cable racks.

The use principle of the palletizing equipment of the present invention is as follows:

First, before starting the palletizing equipment, the data is entered into the control platform of the palletizing equipment according to the relevant parameters of the palletizing position, and then the motors of the palletizing equipment are powered on, and then the palletizing equipment is started, and the palletizing clamping assembly is driven up and down by the first linear motor on the lifting bracket 1, and the palletizing clamping assembly is driven to move on the horizontal plane by the second linear motor on the first sliding bracket 2 and the third linear motor on the second sliding bracket 3, and the palletizing clamping assembly is controlled to move above the cable bracket to be clamped;

At the same time, the steering motor in the steering motor box 9 is controlled to make the stacking clamping assembly parallel to the two sides of the cable bracket, and then the transmission box 11 drives the first screw rod 13 in the clamping control box 5 to rotate, so that the two second sliders 19 on the first screw rod 13 in the clamping control box 5 move away synchronously, and the second slider 19 drives the clamping block 6 to separate, and then the stacking clamping assembly continues to descend, and stops descending when the bottom end of the clamping block 6 is close to the bottom end of the cable bracket;

Then, the clamping control box 5 controls the clamping blocks 6 to approach each other to clamp the cable bracket. When the cable bracket is clamped and pressed, the rubber strip 24 on the side of the rotating wheel 20 contracts. The contracted rubber strip 24 can better clamp the cable bracket to prevent the cable bracket from slipping or falling.

In order to cope with a variety of cable supports, a support block 21 is extended outward from the bottom of the clamping block 6. The equidistant convex structure of the contraction support block 21 can drive the cable support placed on the transmission roller support to move upward. The transmission roller support is equidistantly provided with spaced rollers, and the intervals cooperate with the convex structure of the support block 21, so that the clamping block 6 can be conveniently clamped from the bottom of the cable support. The pressing block 10 arranged below the clamping control box 5 can not only limit the cable support whose length is less than the length of the clamping block 6, but also move down to press down the overly long cable support to prevent the overly long cable support from slipping due to unstable center of gravity. The rotating wheel 20 arranged at the side end of the clamping block 6 can better adjust the stacking position of the cable support to avoid affecting the subsequent stacking. At the same time, when the cable support is adjusted horizontally by the rotating wheel 20, the oil-soaked cotton pad on the support block 21 can be used to oil the bottom of the cable support back and forth to prevent rust.

Finally, the stacking clamping assembly moves the cable holder to the specified position and changes the stacking direction in sequence according to the number of stacking layers. Then the stacking clamping assembly descends to a certain height, and the clamping block 6 releases the cable holder. After the cable holder falls, the stacking clamping assembly will continue to clamp and stack the cable holder according to the instructions of the control platform, and the stacking of the cable holder is completed.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
