Description

Technical Field

[0001] The utility model relates to the technical field of palletizing equipment, in particular to a turnover box palletizing clamping and fixing device. Background Art

[0002] In the storage warehouse where processed and manufactured products are stored, stacking lifting equipment is needed to move and stack the turnover boxes loaded with products, so as to facilitate the transfer of the turnover boxes. The stacking lifting equipment is mainly composed of a robotic arm and a clamping component. The clamping component is responsible for clamping and fixing the turnover box, while the robotic arm is responsible for moving the clamped turnover box.

[0003] There are many types of clamping assemblies, and their main working principle is to use the clamping plates at both ends to approach each other to clamp the turnover boxes. However, when there are many turnover boxes that need to be moved and they are crowded on the ground, the adjacent turnover boxes are too close, so the two clamping plates responsible for the clamping function are not convenient to insert on both sides of the turnover box for use. If there is no slit on the ground, a type of clamping assembly with supporting forks at the bottom will easily squeeze and push the adjacent turnover boxes when inserted into the bottom of the turnover box, causing inconvenience in use. Therefore, for this kind of complex situation encountered, the existing clamping assembly is not convenient to use, resulting in low efficiency in handling turnover.

[0004] Therefore, in response to the above-mentioned situations encountered in actual processes, first, the turnover boxes are relatively close to each other, and the clamping components of the splint type at both ends are not convenient to insert into the two sides of the turnover boxes for use; second, there are no slits on the ground surface, and the clamping components with supporting forks at the bottom are easy to squeeze and push adjacent turnover boxes when inserted into the bottom of the turnover box, resulting in inconvenience in use and low handling efficiency during the process. A turnover box stacking clamping and fixing device can be designed. By controlling the lifting plate to descend, the triangular card is inserted to expand the gap between the two adjacent turnover boxes, the splint is controlled to cooperate with the lifting plate to clamp the turnover box, and the robotic arm is used to control the turnover box to lift a certain height. The support plate is controlled to push each supporting fork into the bottom of the supporting turnover box, and then subsequent transfer operations are performed to solve the problem of inconvenient clamping of this type of turnover box and improve transfer efficiency.

The supporting fork 12 is prone to squeezing and pushing adjacent turnover boxes when it is inserted into the bottom of the turnover box. The clamping assembly in the device solves this problem well. It is easy to use and has stable clamping, which improves the transfer efficiency of the turnover box. It solves two common problems encountered by existing robotic arms when driving the clamping assembly to transport turnover boxes. First, the turnover boxes are relatively close and crowded, and the clamping assemblies of the type of splints 9 at both ends are not convenient to be inserted into both sides of the turnover box for use. Second, there is no slit on the ground surface, and the supporting fork 12 is prone to squeezing and pushing adjacent turnover boxes when it is inserted into the bottom of the turnover box, resulting in reduced transportation efficiency during the process.
