Development Status of Palletizing Robot Control System

robot technology was used in palletizing tasks as early as 1970. The earliest use of palletizing technology in industrial sites was Japan and Sweden. Later, with the advancement of advanced technologies such as computer technology and servo motion control technology, Germany, Sweden, Japan, the United States and other countries have developed rapidly in the field of industrial robot research, and their robot technology related to palletizing has also made comprehensive progress. , The palletizing robots developed by companies such as ABB in Sweden, KUKA in Germany, and FANUC in Japan have come out one after another.

The IRB series palletizing robots developed by ABB, from the earliest IRB6, to the 1RB460, to the IRB760 robot, adopt a 4-axis structure and are equipped with ABB's special motion control software QuickMoveTM and TrueMoveTM to achieve precise positioning of the target, repeatable positioning accuracy It can reach 0.05mm, its load running speed can reach 880 cycles/hour, the maximum load capacity can reach 450kg, and the working range can reach 3.2m. Great progress has been made in all aspects and is used in many fields. ;

The KR300-2PA palletizing robot developed by KUKA has a 5-axis structure and uses the KR C2 control system to perform high-speed and high-load palletizing work. Within 0.08mm, it can ensure the stability and reliability of operation, and its life can reach ten to fifteen years.

The M-2000iA palletizing robot produced by FANUC in Japan is a 6-axis robot. It adopts advanced R-30iA control device for control operation. Its maximum handling load can reach 1350kg, its movable range can reach 6.2m, and its work efficiency can reach 1800 bag/hour, and at the same time using advanced control system, the performance of the whole machine has been greatly improved.

Compared with the palletizing robots manufactured by ABB, KUKA, FANUC, etc. abroad, we must admit that there is still a gap in the development level of domestic robots. Universities and scientific research units have successively made major breakthroughs in many key technologies such as software, hardware design and manufacturing, control, and kinematics of robots. With the advancement of robot technology, the development of palletizing robots has also achieved good results.

The two-degree-of-freedom Cartesian coordinate palletizing robot successfully developed by Harbin Institute of Technology and applied in the actual working environment, its handling speed can reach 800 bags/hour, and the repeat positioning accuracy is ±0.2mm: Shenyang Xinsong is a domestic robot The representative of the research and development level, the SRM160A/300A series palletizing robot developed by it, optimizes the control system and structure, improves the rigidity of the manipulator, its load capacity can reach 300kg, and its working range is 3.15m, which can meet the palletizing requirements of various occasions. Work applications; there are also TPR series palletizing robots jointly developed by Shanghai Wodi Technology and Shanghai Jiaotong University, whose working speed can reach 1600 bags/hour, which meets the needs of palletizing functions.

Palletizing robots drive the development of conjugation technology

The palletizing robots we see in the movie cannot walk and dance. The "humanoid" robot is a multi-disciplinary automation equipment integrating advanced technologies such as machinery, electronics, control, computers, sensors, and artificial intelligence. It can replace manual work in simple and repetitive work, not only can improve production efficiency, ensure product quality, and promote industrial technology upgrading.

Using industrial palletizing robots is also an effective way for companies to reduce labor costs. Grab the packaged goods, move them to the designated position, put them down and tidy, automatically encode them on the pallet, and repeat picking up, shifting, putting down, and picking up again. Different from the mechanical palletizer, when the volume, shape, etc. of the item changes, it only needs to be slightly modified on the touch screen. It can be widely used in the handling, disassembly and placement of production lines of liquor, beverages, petrochemicals, and pharmaceuticals. From packaging bags to cartons and barrels of materials, from stacking one product to a variety of different products, it is more efficient and adaptable.

In recent years, in the Pearl River Delta, Jiangsu, Zhejiang and other densely populated areas of manufacturing enterprises, industrial robots have begun to replace labor with industrial robots in operations in monotonous, frequent operations, gluing, welding and other dangerous and harsh environments such as palletizing, loading and unloading materials, and packaging. Manufacturing companies in the Pearl River Delta use robots.

The annual growth rate reaches 30% to 60%. Tengyang Intelligence believes that the technology of industrial palletizing robots is becoming more and more mature, and the focus is on the scale and industrialization of industrial palletizing robots. In the future, it will develop rapidly in the direction of standardization, light weight and intelligence.

The gradual standardization of the functional parts of the palletizing robot and the combination of modules can reduce the manufacturing cost and the reliability of the lifting rod, reduce the weight and installation space, and make it possible for more enterprises to purchase and use.

The factory palletizing work is very tiring, with more labor and high wages. Due to the emergence of palletizing robots, more and more enterprises, logistics, food, petrochemical industries, and palletizing robots play an increasingly important role. Accurately and effectively complete the palletizing operation, and can reduce labor intensity and improve product quality.
