Air-jet loom weft way is to use compressed air jet out for traction on the weft, the weft take-off shed, the biggest characteristic of fast speed, high labor productivity, and patterns suitable for plain fabrics, fine fabrics and high-volume special high density fabric production, is not the most advanced weaving machines, the most mature products. Air-jet loom through the warp tension sensor detect the total tension, the CPU control from the opening song by, off, by the axis of the coil diameter changes in warp tension changes occur, to ensure accuracy and to the warp let-off to maintain constant tension. And off by electrical control agencies, according to loom Stop of computer-controlled extension of time to weave axis reversed. As the jet loom of the computer technology and other electronic Jishu, the whole machine of the movement control, especially for automatic control of product quality, Shide jet loom greatly improve production efficiency, product quality Baozhang. Loom also installed a lot of monitoring sensors, making loom with automatic operation and process control functions. Currently domestic electric control system of air-jet weaving all the basicThe requirement has the following features: 1, electronic take-up function; 2, electronic let-off: a single beam, dual-beam two; 3, weft control: 4-color free weft, weft storage methods are the major FDP and IRO fixed length type two; 4 weft control: up to 4 main jet, four shear spray or auxiliary main nozzle, 18 auxiliary jet, a stretch of high and low pressure spray control; 5, electronic dobby: 16 electronic dobby; 6, loom motor control: forward and backward, express, parking, is looking for Wei, anti-find latitude, reactor trip, short-wai, Cheung-wai, breaking through, twisted side, waste yarn break detection, edge detection; 7, width wider, usually to 360 mm, more and more into the latitude rate, generally to 1800 m / min; As the domestic textile and mechanical requirements electric control system, high performance, good stability, easy maintenance, low failure rate, the best can be used to buy back, with a few years not to maintenance, because manufacturers basically no professional electrical maintenance engineer; requirements can adapt to high temperature and humidity, more hairiness and dust, power fluctuationsLarge group of machine interference, long-term work for 24 hours a day, most of the factory conditions are generally less than; short various market very, very strict, but tighter price controls. OMRON jet looms in the overall applications (the right picture shows the air-jet loom control system OMRON physical map), the angle sensor uses OMRON s E6B2-C-type incremental photoelectric encoder, can accurately locate any given loom point of view, control accuracy of 1 degree. The encoder signals the way to the PLC to provide perspective, all the way to the valve control panel to provide angle signal. Controlling part adopts OMRON Corporation CP1H series CP1H-XA40DT-D PLC, the PLC built-in powerful and specific functions and control objects are as follows: [This total of 2, the current is the first1] < < Previous Next > >
