Abstract

The invention provides a kind of weft control device which can be used as weft control device to precisely and easily control on the delivering length of the weft. The device comprises the weft length detection device composed of measuring roller and pinch roller, the weft delivering device composed of gripper and nozzle; and the weft reaching sensor at the weft reaching position of the weaving machine. The feature is that the weft control device applies the following steps: memorizing the real measured value of weft reaching detected by the weft reaching sensor; calculating the average of weft reaching values by a certain shuttle engagement number; and, comparing the average reaching values and the predetermined reference targeted values; and, with the comparing result from the last step to control the weft length measuring device.

When the difference between the average arrival value Dh and the target value Dm is large (for example, 10 ° or more), the timing of the pinch stick lb 0N timing Dn / Df is changed. By repeating the above control, the weft yarn sending length can always be kept constant. The present invention is set to: compare the average arrival value of the weft yarn measured at the weft yarn to the reed position with the reference target value; according to the comparison As a result, the operation of the measuring stick or pinch stick is controlled by the weft length measuring control unit, so that it is not necessary to require human hands as in the conventional device, and the weft yarn sending length can be adjusted automatically and correctly. In addition, since the average value calculated from a certain number of shuttles is used as a comparative measurement value, it is possible to mitigate sudden abnormal changes in weft insertion, and it is possible to implement constant and stable adjustments.
