BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the electric wire detecting device of the present invention will be described. In FIG. 1, the kink detection roller 1
3a is a wire take-out roller 12 from the wire winding drum 10.
The electric wire 11 which is fed out via a and 12b is rotated to come into contact with the electric wire 11 to detect the kink state of the electric wire 11. Inner contact 15
a is an electric wire provided near the kink detection roller 13a
It is pushed and bent by the kink portion of 1. Outer contactor 1
6a is provided close to and parallel to the inner contactor 15a,
Due to the bending of the inner contactor 15a, the inner contactor 15a
Contact with. In the kink electric wire detection device according to the second aspect, the kink detection roller 13a and the inner contactor 15a are provided.
And a second detection device including a first detection device including an outer contactor 16a and a kink detection roller 13b provided in parallel with each other to detect a kink condition of the electric wire 11, an inner contactor 15b, and an outer contactor 16b. And a detection signal 2 obtained from the first and second detection devices.
4, 25 are detected by the kink signal detectors 24A, 20B, and the arithmetic processor 22 connected to the kink signal detectors 20A, 20B calibrates the time difference to calculate the truth and output the kink signal 27.

That is, FIG. 1 shows a configuration of an embodiment of the present invention, which is an embodiment of an electric wire drawing device having a kink detecting device 23. The electric wire drawing device of FIG. 1 includes an electric wire winding drum 10, an electric wire 11 drawn out from the electric wire winding drum 10, electric wire take-out rollers 12a and 12b for stabilizing the drawn-out position of the drawn electric wire 11, and a kink. Kink detection rollers 13a, 13 for detecting the portion 7
b and the inner contacts 15a, 15 for catching the kink portion 7
b and outer contacts 16a, 16b, and fulcrums 18a, 1 for stabilizing the operation of the contacts 15a, 16a.
8b, springs 14a and 14b, adjustment grooves 17a and 17b for adjusting the positions of the contactors 16a and 16b, and detection signals 24 and 25 generated by contact between the contactors 15a and 16a or the contactors 15b and 16b. , A kink signal detector 20A, 20B for detecting a signal, and an arithmetic processor 22 for confirming that the kink portion 7 is generated at the same position.
And a straightening roller 19 for straightening the distortion of the electric wire 11.

FIG. 2 shows a case in which no kink has occurred in the electric wire passing through the electric wire take-out rollers 12a and 12b, and FIG. 3 shows a case in which a kink has occurred. In the case of FIG. 3, the kink detection roller 13a is shown. Sandwiched between the contact 15a and
