Description

Detailed Description of the Invention (Technical Field) The present invention involves binding knitted or woven fabrics in the form of ropes, performing a treatment such as kneading dyeing, and then returning the fabrics to their original flat state. Screw number 1 used in a torsion straightening device for straightening torsions. Regarding the detector.

(Prior art) This type of torsion straightening device is composed of a series of devices and L7 in combination with a cloth spreading device, but the performance of the 41mm cloth device is often dependent on the torsion straightening device, and the performance of the torsion straightening device is The superiority or inferiority of the torsion detector is determined by the detection sensitivity of the torsion detector.

Conventional torsion detectors use a piece of fabric (
A piece of underarm fabric (called armpit fabric) is sandwiched between two wavy plates that have a triangular wave cedar shape on the inside, and is placed along the running fabric in the same way.
From K, the wavy plate tilts left and right around its support axis.
Some devices use switch elements for detection. But this detector...

In the case of a narrow rope of narrow width or thin fabric, the torque for tilting the corrugated plate from side to side is weak.

If there are many torsions 1, the bu ζ has the disadvantage that it does not adapt to the corrugated plate and becomes undetectable.

In addition, a detector has been devised that detects twist from the movement of the gear by placing a twist [-wa] along the uneven surface of the tooth tip of a spur gear. Since the medium had to remain stationary and the torque was determined by the twist (7 degrees) of the fabric itself, it was not possible to detect a thin rope-like object.

(Object of the Invention) The present invention was invented in view of the above-mentioned situation, and the detector +9 is made highly sensitive, and even in the case of a thin rope-like fabric, the screws can be easily removed. The purpose of the present invention is to provide a torsion detector for a fabric that is restrained in a rope-like manner so as to be able to detect (1ζ).

(Structure of the Invention) In order to achieve the above-mentioned object, 1) a rope-like restraint type! 7-piece of fabric is inserted along the gap of 7, and the tip is completely inserted into both sides. A flat plate having a reflective surface; disposed on both sides of the tip of the flat plate; 11; irradiating the flattened tip; 2. It is equipped with a photoelectric switch that is activated by the reflected light.

In the present invention, when a screw 1t occurs in the fabric, the reflection point on one side of the tip of the flat plate is blocked by the 1.7th groove of the fabric due to the action of the screw 1 (, wa), and therefore -7
Only one of the photoelectric switches is activated, thereby making it possible to detect sagging. Also, by knowing which photoelectric switch is activated, the direction of twist can also be detected.

(Example) Embodiments of the present invention will be explained below based on the drawings.

1 - J,

As shown in the eleventh line 1, the fabric 1 is guided by the drum wheel 2 to a certain point n, and runs in the direction of the arrow 6.

4 flat plates, both sides (1111It is a thin plate with a light reflecting plate on one side, and its tip is placed in the gap between the fabric 1 and the groove)
Insert - J J. Reflective light 711 switches 5a+5b are arranged on both sides of the tip of the flat plate 4, each switch 5a+5b PJ, light running arrow 6a, 6h
It works by reflecting the light. The detection action f will be explained as follows based on FIGS. 2 to 4 when this state is viewed from above.

FIG. 2 and FIG. 6 both show a state in which there is no twist. In Fig. 2, the rope-like diameter of the wide or thick fabric is large, the tip of the flat plate 4 is inserted deeply along the crease gap, and the light reflection point is blocked by the (, 7 wrinkles) of the fabric 1. , both of the photoelectric switches 5a and 5b are not receiving reflected light, and neither switch 5a,
5b is not working either.

Figure 5 shows a rope-shaped piece of thin fabric with a narrow diameter, the tip of the shohei plate 4 shallowly inserted into the crease gap, and the point of reflection of light being drawn in by the wrinkles of the fabric 1. However, both the light heavy switches 5a and 5b are receiving reflected light G', and the switch 5a of Izu fi is in a state G'.
, 51) also operates E, 7.

In this manner, it can be seen that when the screw fl is not present, the output signals of the optical +1j switches 5a and 5b are the same, that is, both are off signals or on signals.

Next, in the 41st case 1t, a state in which the fabric 1 is sagging is shown. When the screw fl is generated, due to the action of "twisting 1° 7 degrees", the tip of the flat shank 4 is centered at 11
．． This causes the cap to shift to either the left or right side. Here, the number is 11, and the state shown in the direction of arrow 7 is shown.

In such a state, light 717. The switch 5a can receive the reflected light, but the light switch 5h can receive the reflected light.
: 1 point is shielded by the wrinkle of cloth cotton 1.

Cannot receive reflected light. Konoda W), Hikari'F1
9 only the switch 5a is activated, and the photoelectric switch 5b is activated.
No rt+ l-2. Therefore, if there is twist, t,1
．． The output signals JF'F of each photoelectric switch 5a, 5b are different. In other words, it can be seen that one signal becomes a -kaba-on signal, and the other becomes an off signal. Furthermore, the direction of twist can also be detected by the on/off signal of -zo.

For this reason, if the output resistors of the optical switches 5a and 5h are connected to the i11 circuit consisting of the logic 1 circuit, the presence or absence of the screw ti and its direction can be automatically detected. What you can do is 1/7.

(1) Achievement of the invention As is clear from the above i(?, clear), the device according to the present invention is capable of detecting the twisting of the fabric.
The chewing motion of the cotton ladle caused by the cotton grain body due to the action of "twisting wrinkles" is configured to be detected by the C wheel switch, so there is no need for torque to move the detection medium as in the conventional technology. Therefore, there are 61 highly sensitive IJP detections. Therefore, as described above, detection is possible regardless of the thickness of the lobed if diameter of the fabric or the twist state.

, ζ et al. 1 The structure of the extractor is also extremely simple.
