The increasing demand for flexible production capacity in modern chemical plants indicates that the intelligent and automatic production mode has become inevitable. Industrial robots have become an important role in the upgrading of large manufacturing enterprises. In some cases where the environment is harsh and manual operation is not possible, the manipulator can complete the specified procedure instead of manual operation under the control of the established procedure without being limited by time and harsh environment. Such as handling, loading and unloading, grinding, spraying, packaging, etc.
Among them, palletizing robot is one of the most widely used scenarios at present, and occupies a large market share in the industrial robot market.
Especially with the development of artificial intelligence, big data, sensors, machine vision and other information technologies, it has promoted the "industry 4.0" process of the food industry. In the food production, the popularity of intelligent equipment is getting higher and higher. The palletizing robot has greatly alleviated the manual problems in the packaging link of production enterprises and improved the automation level of the whole production line.
Palletizing robot is one of the packaging equipment with a high degree of intelligence at present. It operates flexibly and accurately, is fast and efficient, has high stability, and can greatly reduce the labor intensity. In recent years, the advantages of palletizing robot have become increasingly prominent, and its application scenarios in the food industry are also expanding.
According to industry data, the sales volume of palletizing robots in 2017 was about 43000 units, a year-on-year increase of 33%. It is expected that the market sales volume will exceed 100000 units in 2020, and the market scale is expected to exceed 16.5 billion yuan. In today's huge market sales of robots, palletizing robots account for more than 30%. These data show that the palletizing robot is not only a hot spot in the market, but also a major force in the development of the robot industry in the food industry.
Compared with manual palletizing, palletizing robot has outstanding advantages.
First of all, the equipment has a large operating range and good safety performance. In a straight line, only one motor is used, so the stacking effect is very good.
Secondly, it has strong applicability. Because of the high level of intelligence, when the size, volume, shape of the product and the overall dimension of the pallet change, it is only necessary to make a slight modification on the touch screen, which will not affect the normal production of the production line.
Nowadays, there are not only a large number of palletizing robots, but also a very rich variety of equipment. According to the intelligent level, it can be divided into robot palletizer and mechanical palletizer; According to the working mode: magnetic stacking, side pushing stacking machine, servo stacking, robot stacking machine, etc. Different types of palletizing robots can cope with different working scenarios, and enterprises can choose according to their needs.
The working system of the palletizing robot includes controller, programmer, robot gripper, pallet conveying, positioning equipment and palletizing mode software. Some quilt are also equipped with automatic weighing, labeling and other functions to realize multi-functional integrated operation. Now, with the efforts of technicians, the key parts of the palletizing robot, such as the base, waist, hip, wrist and end actuator, are being optimized, and the overall structural performance continues to improve.
In addition, high intelligence, miniaturization and automatic obstacle avoidance have become the research hotspots in the research field of palletizing robot. On the basis of further integrating the advantages of people and machines, the movement of manipulator, electric slide rail and moving slider is further optimized to achieve higher speed and stable work efficiency.
