The position of an article is transferred by adopting an AGV transfer robot, and the article is inevitably required to be loaded and unloaded. If the article is loaded and unloaded manually, on one hand, the labor cost is increased, and on the other hand, the production automation planning is not facilitated; if mechanical equipment is adopted for loading and unloading articles, some AGV carrying robots are independent loading and unloading equipment and have high cost, and some AGV carrying robots are integrated with loading and unloading mechanisms, such as a manipulator clamping jaw applied to piece placing equipment disclosed in CN 106737801B.
