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.
