喷气织机中的纬纱行进状态监视方法
摘要：
本发明涉及喷气织机中的纬纱行进状态监视方法，准确地监视纬纱的行进状态。织幅内纬纱传感器被设置在比制动开始时刻(BT)的纬纱前端位置靠近引纬方向上游侧，因此能够不受制动器的制动的影响地把握纬纱的种类、引纬喷嘴以及辅助喷嘴的喷射压力的差异引起的行进状态的差别。因此，能够准确地把握基于织幅内纬纱传感器的纬纱中间到达时刻(IS)与气圈传感器的第三次纬纱解舒时刻(B3)的时刻差(Δ)。纬纱中间到达时刻(IS)与纬纱解舒时刻(B3)的时刻差(Δ)能够监视引纬喷嘴的纬纱解舒性能以及辅助喷嘴的纬纱输送性能的平衡状态，能够有助于压缩空气压力、喷射时刻的控制。
摘要（英）：

There is provided a method for monitoring weft traveling condition in an air jet loom that includes a weft measuring and storing device having a drum, a weft stop pin, and a balloon sensor that detects the release of the weft yarn. The air jet loom further includes a weft insertion nozzle, a plurality of sub-nozzles, a brake, and a weft sensor that is disposed within a width of cloth. The weft sensor is disposed upstream of a position of leading end of the weft yarn corresponding to a brake timing of the brake in weft insertion direction. The weft traveling condition is monitored by grasping a time difference between a weft passage timing given by a weft detection signal generated by the weft sensor and a weft release timing given by a weft release signal generated by the balloon sensor.
