題がある。(Prior Art) Conventionally, as means for detecting rope-like torsion in running fabric, for example, the amount and direction of torsion can be detected by bringing the tip of a flat or rod-shaped torsion detection rod into contact with the torsion along the torsion. There is a known method of detecting and activating a twist corrector, but in the case of thin fabrics, it is easy to damage the fabric, and the twisted part has a thin rope shape, so the detection torque is weak and insufficient. If the amount is large, there is a problem in that it is difficult to fit into the detection rod, making detection difficult or impossible.

とができる。 As shown in FIG. 2, a half mirror 5 is placed on the rear side of the lens 4 which is arranged parallel to the traveling fabric W with a required distance therebetween, and is angled approximately 45 degrees from the position parallel to the lens. At the same time, when the two light receiving elements 8 and 9 are arranged in a straight line or in parallel in the manner shown in the same figure, and when the running fabric W is irradiated with light from the light source 1 in this state, the twisted portion 2 of the fabric is
The light rays that hit the convex part are reflected. This reflected light beam 3 is focused by a lens 4 and irradiated onto a half mirror 5, and transmitted light beam 6 and reflected light beam 7 at the half mirror
is projected and imaged onto the light receiving elements 8 and 9. At this time, if the twist angle is 45 degrees with respect to the axial direction of the fabric W, the light receiving element 8 that has passed through the half mirror 5
The upper image 10 remains as it is, but the image 11 on the light receiving element 9 reflected by the half mirror 5 forms an angle of 90 degrees with the image 10 on the light receiving element 8, so both light receiving elements 8, 9 are arranged in parallel as shown, the image 10 on the light-receiving element 8 will be parallel to the light-receiving element, while the image 11 on the light-receiving element 9 will be perpendicular to the light-receiving element. That is, the direction of the torsion of the fabric can be detected by the angles of both images projected onto both light receiving elements, and in this case, the images of the torsion of the fabric can be simultaneously captured by both light receiving elements 8 and 9. Therefore, there is no time delay and detection accuracy can be maintained at a good level.

2 and 13 to produce output voltages e 1 and e 2 , and further, these output voltages e 1 and e 2 are amplified by operational amplifier 14
Then, the equation e 0 = e 1 − e 2 is calculated to generate an output voltage e 0 , and this output voltage e 0 is further amplified to operate a separately arranged twist straightening device (not shown). It is something.

出精度を著しく向上できるものである。(Effects of the Invention) The present invention uses a photoelectric detection means to detect the torsion of the fabric, so there is no need to touch the fabric at all, and therefore the detection rod can be brought into direct contact with the fabric to detect the torsion. It is possible to reliably solve the problem of damage to the fabric, deterioration of detection accuracy due to insufficient detection torque, or difficulty or inability to detect, which is the case with conventional means that Since a unique method of using a half mirror was adopted in this method, the accuracy of detecting the amount and direction of twist in the fabric can be significantly improved.
