Stacking and unstacking device

According to the stacking and unstacking device, after material bag placing information of a pallet area is obtained through a camera, a computer can process the information and position coordinate information of the most flat area of the surface of a material bag to be clamped, and therefore a clamping jaw assembly is controlled to move to the area to conduct accurate material bag adsorption and clamping operation. And the conditions of bag falling and stack collapse are avoided, and good unstacking operation is achieved. Besides, the buffering device can provide a buffering function in the process that the suction cup presses the material belt downwards, the function of the suction cup can be achieved, the function of a pressing plate with the buffering function can also be achieved, products in the material bag are prevented from being crushed due to the fact that the downward pressing force is too large, and meanwhile it can be guaranteed that the material bag cannot move. 本实用新型涉及一种码拆垛装置，通过相机获取到栈板区域的物料袋摆放
