Numerical control system for water jet loom

Abstract

The invention mainly discloses a numerical control system for a water jet loom, which mainly comprises a singlechip, a contactor module, a photoelectric weft detection module, an encoder module, a weft accumulator module and a diversion valve and thread clamper output module, wherein the contactor module receives control signals of the singlechip and controls the work states of a main shaft motor and a moisture absorption motor of the water jet loom through controlling the opening and the closing of the contactor module, the photoelectric weft detection module comprises a photoelectric probe for detecting the weft thread state, weft thread signals are input into the counter door control end of the singlechip through an amplification circuit, the encoder module collects signals of an encoder arranged on the main shaft of the water jet loom, one path of processed encoding signals is transmitted into the singlechip, the other path of the processed encoding signals is transmitted to an electronic let-off and electronic take-up system of the water jet loom, the weft accumulator module transmits weft accumulation signals in a singlechip onto a weft accumulator, and the diversion valve and thread clamper output module respectively transmit diversion signals and thread clamp signals in the singlechip onto a diversion valve and a thread clamper. The numerical control system disclosed by the invention coordinates the integral work of the main shaft, weft insertion and weft accumulation of the water jet loom through the digital technology, the automation technology is high, and the information feedback is rich.

Description

technical field [0001] The invention relates to the field of water jet looms, in particular to the numerical control system of the water jet loom. Background technique [0002] The water jet loom relies on the water flow with a certain pressure, that is, the friction between a certain jet and the fiber, to carry the weft through the shed, so that the warp and weft are interwoven into a fabric. Water-jet weft insertion has greater friction and traction on weft yarn than air-jet weft insertion, and has less diffusivity, which is suitable for weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. [0003] The mechanical equipment technology of water-jet looms became more and more mature in the 1980s and 1990s. The opening device, weft insertion device, weft feeder, and spindle system in traditional water-jet looms are relatively complete, and each component is independent of each other. electrical connections. The quality of the loom fabri...

AI Technical Summary

Problems solved by technology

The quality of the loom fabric is largely determined by the cooperation of the various components. Traditional mechanical equipment lacks a numerical control system for overall control of the weaving process.
