A fixed guide roller 93 is attached to the right end of the upper edge of the front surface of the support plate 74, and three straightening rollers 94 are attached to different heights at the center of the front surface in the left-right direction.

A movable guide roller 95 is attached to the tip of the guide arm 76. The base of the guide arm 76 is integrally provided with an enlarged arm 96 extending in a direction substantially opposite to the direction of the guide arm 76 and having a length of about 5 times the guide arm. Two winding diameter detecting microphotosensors 97 are attached to the tip of the expanding arm 96 side by side in the moving direction thereof. Then, a vertical gauge plate 98 is arranged along these microphoto sensor movement paths. The gauge plate 98 extends along an arc centered around the swing center of the expansion arm 96 and is a microphoto sensor.
It has an arcuate part on the left edge that goes into the working part of 97. A large number of through-hole slits 99 are provided at a constant pitch in this arc-shaped portion.

Referring to FIG. 8, if the pitch of the slits 99 is P1 and the mounting pitch of the two photosensors 97 is P2, P2 is a dimension that is not an integral multiple of P1, for example P1.
When P is 5 mm, P2 is 29 mm. Therefore, the two photosensors 97 are not operated at the same time, and the two photosensors 97 do not operate at the pitch P1 of the slits 99.
The two photosensors 97 are alternately activated each time half of the above is moved.

Next, the winding operation will be described. First, the bobbin B is supported on the winding shaft 27. The guide table backward limit detection micro photo sensor 85 and the guide table forward limit detection micro photo sensor 86 are positioned according to the width of the bobbin B supported by the winding shaft 27. The wire W is pulled out from the supply section S1, wound around the fixed guide roller 93 and the three correction rollers 94 in sequence, and then the tip end is wound around the bobbin B. Then, to abut the movable guide roller 95 from above the wire W between the straightening roller 94 and the bobbin B.

When the take-up shaft motor 54 is operated with the guide table 75 positioned at the backward limit, the bobbin B is rotated and the rotary shaft of the rotary encoder 58 is rotated. When the bobbin B is rotated, the wire W
While being wound up, at the same time, the guide base motor 91 is operated to move the guide base 75 forward. In order for the wire rod W to be wound around the bobbin B in an aligned state, the rotation speed of the bobbin B and the forward movement speed of the guide table 75 must be synchronized. This is because the guide table 75 is rotated during one rotation of the bobbin B. This is achieved by servo-controlling the guide table motor 91 based on the detection signal of the rotary encoder 58 so that the wire is sent by a pitch equal to the diameter of the wire. Thus, the bobbin B and the wire W
Will be wound up one after the other.

When the guide table 75 moves to the forward limit, the guide table forward limit detection microphotosensor 86 detects it, and the guide table motor 91 is reversed based on the detection signal.
This time, the wire rod is wound around the bobbin from front to back.

As the wire W is wound on the bobbin B, the winding diameter gradually increases. Then, the moving path of the wound wire W from the straightening roller 94 to the bobbin B is gradually changed, and the movable guide roller 95 is pushed up by the wire W. Then, the guide arm 76 is swung upward, and conversely, the expansion arm 96 is swung downward. As a result, the two winding diameter detecting microphotosensors 97 move from top to bottom along the arcuate portion of the gauge plate 98, and each time the two sensors 97 pass through the light-transmitting slit 99, Two sensors 97
Outputs a detection signal. The detection signal of the sensor 97 is counted by a counter (not shown). Therefore, the count value of the counter increases as the winding diameter increases.

The rotation speed of the winding shaft 27 is controlled so that the speed of the wire W to be wound is always constant, regardless of the winding diameter. For that purpose, the correspondence between the winding diameter and the counter value may be obtained in advance, and the rotation speed of the winding shaft motor 54 may be controlled based on the current counter value.

When the speed of the wound wire W is constant,
When the front-back direction of the wound wire W is reversed, double winding as shown in FIG. 9a is prevented from occurring.

If the above-mentioned double winding is to occur, the wire W about to be double wound will have
The winding force indicated by arrow F0 in FIG.
As indicated by arrow F1 on b, the component force of the winding force acts on the bobbin B in the direction to move it in the axial direction. as a result,
By compressing one of the double-winding prevention compression springs 43, the movable base 24 is moved together with the bobbin B, and there is no possibility of double winding.
