[Function] In the wire feeding device configured as described above, when the wire in a wound state accommodated and supported in the tray is pulled out via the guide member, the guide member unwinds the wire according to the drawing speed. rotated in the direction The rotational speed of the guide member is detected by the detection means, the motor is driven to rotate based on the detected data, the saucer is synchronously rotated in the same direction as the guide member at the same speed, and the wire is untwisted.

[Example] Hereinafter, an example of a wire rod feeding device embodying the present invention will be described in detail based on the drawings.

As shown in FIGS. 1 to 3, the device main body 1 is formed into a substantially box-like shape with an open bottom, and a bottom M3 having a plurality of legs 2 is attached to the bottom opening. The bearing body 4 is fitted and fixed into a mounting hole 6 on the upper surface of the apparatus main body 1 by a plurality of screws 5, and a rotating shaft 7 is rotatably inserted and supported inside the bearing body 4. The driven pulley 8 is fitted and supported by the rotating shaft 7 so as to be relatively rotatable, and a drawer guide tube 9 having a tapered shape is fixed to the upper surface of the driven pulley 8 by a plurality of screws 10 and a presser plate 11.

The saucer 12 is removably fitted into the drawer guide tube 9 at a cylindrical fitting portion 13 in the center, and a wire W such as a wound electric wire is accommodated and supported on the upper surface thereof. 〃Id member 14
is screwed and fixed to the upper end of the rotating shaft 7 above the drawer guide cylinder 9, and a plurality of guide rods 15 for guiding the wire W drawn out from the receiving tray 12 are provided to protrude in the radial direction.

A motor 16 capable of forward and reverse rotation is fitted and fixed into a mounting hole 18 on the top surface of the device main body 1 with a plurality of screws 17, and a drive pulley 20 is mounted on a motor shaft 19 at the top. The belt 21 is installed between the drive pulley 20 and the driven pulley 8, and when the motor 16 is rotated, the drawer guide tube 9 and the tray 12 are rotated via the drive pulley 20, the belt 21, and the driven pulley 8. be done.

The detection plate 22 is attached to the lower end of the rotating shaft 7 with a nut 23 or the like within the apparatus main body 1.

First and second 7-point sensors 24.2 as detection means
Reference numeral 5 denotes light emitting elements 2 which are disposed close to each other at a predetermined interval within the main body 1 of the apparatus, and which face vertically across the rotation locus of the detection plate 22.
6 and a light receiving element 27, respectively.

Then, when the rotating shaft 7 is rotated in the 412I clockwise direction via the guide member 14 as the wire W is drawn out, detection signals are output in the order of the first photo sensor 24 → the second photo sensor 25. It is detected that the rotation direction of the rotation shaft 7 is clockwise, and the rotation direction of the rotation shaft 7 is detected based on the number of detection signals generated from the first photo sensor 24.
rotation speed is detected. Furthermore, when the rotating shaft 7 is rotated counterclockwise, a detection signal is output in the order of the second photo sensor 25 → the first photo sensor 24, thereby indicating that the rotating direction of the rotating shaft 7 is counterclockwise. At the same time, the number of rotations of the rotating shaft 7 is detected based on the number of detection signals generated by the second photo sensor 25. Based on this detection result, the rotation of the motor 16 is controlled via a control circuit (not shown), so that the drawer guide tube 9 and the tray 12 are rotated in synchronization with the guide member 14 in the same direction and at the same speed.

It is introduced and set into a processing device such as a wire cutting device (not shown). In this state, when the wire W is pulled out from above the tray 12 as the processing device operates, the guide member 14 is rotated in the unwinding direction in accordance with the speed at which the wire W is pulled out. The rotational direction and rotational speed of the guide member 14 are detected by the photosensors 24, 25, and the motor 16 is rotationally driven based on the detected data, so that the saucer 12 and the drawer guide cylinder 9 are moved in the same direction as the guide member 14 at the same speed. are rotated synchronously.
