Manual handling and palletizing can no longer meet the production needs of enterprises. Stackers are widely used in packaging machinery industry. Cooperative stacker has the advantages of simple structure, small volume, light weight, fast speed, safety, energy saving, beautiful appearance, etc. The power of the whole machine is smaller than that of the traditional stacker, which can save a lot of electric energy every year. And it can greatly shorten the length of the production line, reduce the number of equipment, and simplify the process.

The labor intensity of manual stacking is high, and the turnover rate of post labor is high, which has a serious impact on production management. With the development of science and technology, the appearance of automatic stacker saves time and energy for product stacking, and can better help enterprises to complete transportation tasks.

The disadvantages of manual palletizing of cooperative palletizing robot are pointed out: the palletizing form is irregular, the palletizing is often reversed, and there are potential safety hazards. In the loading process, due to the irregular stacking form, the loading capacity is low and the transportation cost is high. Low stacking efficiency and high labor cost.

The future intelligent factory is created by the harmonious coexistence of people and machines. It requires robots to cooperate with humans and complete different tasks with humans. This includes not only the traditional tasks of "people can't do it, people don't want to do it, and people can't do it well", but also complex tasks that can reduce human labor intensity and improve the quality of human life

Because manual handling and palletizing cannot meet the needs of industrial production, the R&D and production of full-automatic and full-automatic handling and palletizing machines continue to accelerate. The structure of the fully automatic handling and palletizing machine is mainly composed of the power distribution cabinet, the main stacking behavior, the bag shaping and beautification, the bag body transmission, the pallet collection, the filling, handling and palletizing.

In recent years, a variety of warehouse automation machines and equipment have appeared in China. How to use automated machines to improve the efficiency of warehousing operations and reduce labor seems to be the concern of the warehousing industry at this stage. From process planning to software and hardware design, the specific conditions of the construction site should be fully considered. The invention can improve the limit under complex scenes and achieve efficient operation

Most of the operations performed by the cooperative palletizing robot are grasping and placing operations, that is, the robot grabs materials from the conveyor belt and places them on the designated position on the pallet along the motion path. Therefore, according to the position relationship between the robot and the conveyor belt and tray when it completes stacking, and considering the obstacles in the movement process, the "door" shaped movement track is selected. It should be noted that when the robot end effector completes the stacking of cartons at different positions on the pallet, the trajectory is in the shape of a "door", and the coordinates of the trajectory end point are different only because the positions of cartons on the pallet are different.

Collaborative robots are used in the process of sorting out enterprise related emergencies, and can complete collaborative work that can only be completed by multiple people at a faster speed. This kind of robot is suitable for enterprises with gradual development of industrialization and scale, and can solve many difficult and complex problems. So what should enterprises pay attention to in the early stage of selecting cooperative robots?
