Development of Check up System for Picking Mechanism on Water Jet Looms

Abstract

A check up system for picking mechanism on water jet looms is developed. This system catches the signal of water jet pressure with a pressure sensor, and detects the open-close of a clamper with a clamper sensor respectively, and measures such values as water jet pressure, jetting angle and flight start angle of weft yarn etc. As these measured results, this system can find the best condition of picking mechanism for weaving.This system is available for preventive maintenance of picking mechanism, and contributes to decrease loom stoppage and poor condition of weft flying resulting in improvement of flexible manufacturing.
