The Automation Level Of Foreign Air Jet Looms At Present

Since the first introduction of 12 air-jet looms (Tsudakoma) ZA200 by the Shanghai weaving Research Institute in 1982 for the purpose of weaving the relevant varieties, the study of domestic air-jet looms has been conclusive on the two types of jet weft insertion technology, which are using gas supply pipes separately and using the special reed relay to spray centralized gas supply. Up to now, there are nearly 10 factories in nearly 6 countries, and about 32 different types of air-jet looms are about 110 thousand.

In the overall technical level, the main control system of foreign air jet looms is generally controlled by 32 computers. Other auxiliary movement systems such as main jet, auxiliary spray, draft nozzle and solenoid valve, such as weft insertion control system, electronic let off and take-up system, and opening system, can be effectively controlled. It can collect, monitor, set up and adjust various process parameters in real time, and has the function of fault diagnosis. Through the Internet, industrial Ethernet and fieldbus, loom remote networking control and management can be realized.

The highest speed of imported air-jet looms can reach 800 R / min at home, and the weft insertion rate exceeds 1500 m / min. The loom has high mechanical and electrical integration and good reliability.

In recent years, the number of imported 15 thousand air-jet looms has been introduced annually, accounting for nearly 85% of China's air-jet loom Market.

Although the introduction of a large number of models, but the number of imports is mainly concentrated in Japan's Tsuda Ko (Tsudakoma) company, Japan TOYOTA (Toyota) and Belgian Picanol (three companies) products; also introduced some of Italy Somet and Germany's Dornier products.
