The rotation of J 85 a is caused by a belt 86 to pass through idle pulleys 87, 88, 89, 90 to a driven roller 8 coaxially fixed to the first supply roller 75 of the wire insertion device 56.
The drive rollers 91 and 92 that drive the rollers are rotated. The drive roller 91 is pressed against the driven roller 80 of the wire insertion device 56 by a spring (not shown) at the wire feed-in position shown by the solid line in FIG. It is designed to come into pressure contact with the

Furthermore, on the left side of the wire reversing and inserting device 55, a strainer 96 is provided to clamp and feed the wire during wire feeding, and to correct the bending of the wire. The strainer 93 has a pair of jaws 94,95 (FIG. 11) that can be opened and closed.
The wire is clamped with a predetermined clamping force. Photoelectric detection devices 97 and 98 are provided between the wire reversing and inserting device 55 and the strainer 96 to detect the presence or absence of the wire 2.

Next, the operation of the wire reversing and inserting device 55 will be explained.

The wire insertion device 56 is in the retracted position shown by the solid line in FIG. 10, and in FIG. 12, the pushing lever 96 rotates counterclockwise due to the rotation of a cam (not shown) and presses the front-rear sliding shaft 67. The guide rail 6 together with the longitudinal moving body 65

The fixed cap 773 is inserted into the upper side. At this point, when the wire 2 coincides with the center line of the guide cap 77, the forward and backward moving body 65
A stopper screw 62a whose front end is provided on the support body 62
Although the front-rear movable body 65 stops when it hits, the push-out lever 96 rotates further, and only the front-rear slide shaft 67 moves forward against the compression spring 74. As a result, the tip of the front-rear sliding shaft 67 pushes the second L-shaped lever 86, rotates the first L-shaped lever 81 that engages with it in the clockwise direction, and moves the second supply roller 76 along with the movable base 77b to the position indicated by the chain line. Move it to the closed position shown by the solid line and close it. The wire 2 is thus guided to the guide cap 77 and held by the rollers 75 and 76.

Subsequently, the gripping claws 46, 44 of the wire gripping head 36 open, the gripping head 36 releases the wire 2, and the reciprocating swinging arm 28 reverses, and the reciprocating swinging arm 28, the head support base 61
and the wire gripping head 66 returns to its original position.

Next, the strainer 96 pinches the wire 2, and the air cylinder 16 of the cutter clamp device 8 is activated to cutter 11,
12 cuts the end of the wire, and at the same time, the clamp jaw 16 grips the tip of the wire on the bobbin 1 side. The wire has now been cut to a predetermined length.

Next, the rotation of the motor 85 shown in FIG.
rotates clockwise. As shown in FIG. 10, the driving roller 91 (which is in pressure contact with the workpiece driving roller 80) rotates the driven roller 80 and the first and second supply rollers 75 and 76 that sandwich the wire 2, and the strainer 93 The wire 2 is retracted through the wire 2. At this time, it is recommended to blow air from below and let the wire escape upward to prevent the wire from getting tangled.
When the rotation of the motor 85 reaches 98, the rotation of the motor 85 is stopped, the retraction of the wire is completed, and the tip of the wire 2 is located at the tip of the guide cap 77.

Next, the support body 62 is moved by a predetermined distance to the right by a cam and a link mechanism (not shown), and accordingly, the fixed rank 7
0 rotates, and the support 66a, the first
Then, the wire insertion device 56 consisting of the second supply rollers 75, 76 and the guide cap 77 is rotated counterclockwise about the sleeve 66, and is reversed and moved to the chain line position E in FIG.

As a result, the small diameter side of the guide cap 77 faces in the wire supply direction, and the tip of the guide cap 77 approaches and opposes the winding hole of the core 100 that has been arranged in advance. Subsequently, the motor 85 reverses counterclockwise, and the drive roller 92, which comes into contact with the driven roller 80 by reversing, rotates counterclockwise in FIG. Insert it into the hole. At this time, wire 2
The tip of the guide cap 77 is guided, and the small diameter side of the core 1 is guided by the guide cap 77.
Since it faces the winding hole of core 1000, even if the wire 2 is slightly bent, it is fed straight to the tapered surface, and the wire 2 is reliably inserted into the winding hole of core 1000.

Next, a wire holding device for holding the wire 2 through the core 100 will be explained with reference to FIGS. 15 to 17. This wire holding device consists of two guide rails 102 fixed to the frame 101 parallel to the wire supply line.
．． 10'5; a suction tube 106 having a holding vibrator 105;
6 and a wire gripping roller device 108 attached to a support 107 slidably fitted to the wire gripping roller device 108. The wire gripping roller device 108 includes a pair of upper and lower levers 111 and 112 that are swingably attached to the support body 107 by a shaft 110;
Gripping rollers 113, 114 mounted opposite to the tip
and? Both levers 111 and 112 have springs 115
The rollers 113 and 114 are urged to press against each other. A pair of horizontal rollers 116 and 117 are provided on the support 107, and the support plate 1 is mounted on the frame 101.
The support body 107 is prevented from rotating by sandwiching guide rails 118 which are attached through the guide rails 19 and parallel to the guide rails 102 and 106.

On the other hand, a pair of rollers 120 and 121 are attached to the frame 101 and abut against cam surfaces 122 and 126 formed at the rear of the lever 111 and 112, respectively. Support 10
7 is a spring 124 provided between the movable table 104
15, and is stopped at the position shown by the solid line in FIG. 15. In the illustrated retracted position of the moving table 104, the cam surface 122, 126 hits the roller 120, 121, and the lever 111, 112 opens. Gripping roller 113.114
is slightly away.

Next, the operation of holding the tip of the wire will be explained.

The moving platform 104 moves toward the left in FIG. 15 on the guide rail 102.
When the device starts moving forward along the guide rail 103, the suction tube 106, the support body 107, and the wire gripping roller device 108 also move forward along the guide rail 118.

When the support body 107 comes into contact with the support plate 119, the wire gripping roller device 108 stops and only the suction tube 106 moves forward, and the pair of gripping rollers 116.
114 is pushed open, and the holding pipe 105 stops at a position close to the winding hole of the core 100.

Next, as described above, the wire 2 is inserted into the winding hole of the core 100 by rotation of the driving roller 920, and its tip is inserted into the holding pipe 105 and held. At this time,
A vacuum pump (not shown) is activated and the holding pipe 105 vacuums the wire 2 into the core 100.
The wire can be inserted more reliably into the winding hole. When the wire 2 is inserted by a predetermined length, the moving platform 104 begins to retreat. The holding pipe 105 is connected to the gripping roller 113.11.
4, the gripping rollers 116, 114 grip the wire due to the biasing force of the spring 115. At this point, the vacuum suction is stopped and the moving table 104 is further retreated, causing the wire gripping roller device 108 to retreat and the wire to be pulled out of the winding hole of the core 100 by the gripping rollers 116, 114. The movable table 104 once stops near the retreating end, grips the wire 2 with rollers 142 and 146 of a reversing winding device, which will be described later, and then retreats further to reach the retreating end shown in FIG. Cam surface 122.126 abuts roller 120.121, lever 111.112 opens and gripping roller 116.114
Release the wires apart. Thus, the tip of the wire has passed through the hole in the core and been pulled out. On the other hand, the wire insertion device 56 is reversed and returned to its original position by the operation opposite to that described above, and the push-out lever 9 of FIG.
6 is retracted, and the wire insertion device 56 is also retracted to the retracted position.

Next, a reversal winding device for returning the tip of the penetrated wire 2 to the original insertion side will be described with reference to FIGS. 18 to 20. As shown in FIG. 19, a shaft 131 is rotatably attached to a frame 160, and is reciprocated by power transmitted to a gear 132. axis 161
A driving arm 166 is fixed to the end of the frame 160, and a driven arm 164 is connected to the shaft 161 inside the frame 160.
The top is rotatably mounted. A support shaft 165 extending perpendicular to the wire is fixed to the tip of the drive arm 133, and another support shaft 16 is fixed to the tip of the driven arm 134.
6 ends are fixed. Links 167 and 138 that connect each other are rotatably fitted to both support shafts 135 and 166, and their tips are connected to each other by a shaft 140, and the shaft 1
A torsion spring 141 wound around 40 biases both support shafts 135 and 136 toward each other.

The support shafts 135 and 136 extend to the supply line of the wire 2, and a roller 142 is mounted at the tip thereof so as to sandwich the wire 2 from above and below.
．． 146 is rotatably mounted. In the standby position shown in FIG. 18, the tip of the driven arm 164 hits the stopper 145 shown in FIG. , and are stopped in the position shown in FIG. 18, whereby the links 167, 168 open into an obtuse V-shape and the rollers 142, 146 are separated.

Next, the operation will be explained. In Figure 15, wire 2
When the gripping rollers 116, 114 pull out the wire 2, the rollers 142, 146 are in the position shown in FIG. 17, waiting above and below the drawn wire 2. Following the completion of drawing out the capital, the drive arm 166 begins to rotate counterclockwise in FIG. 18, and the roller 142 comes into contact with the wire 2.
Pick up the dough. When the roller 142 hits the roller 146, both rollers grip the wire, and the roller 146 is lifted from the stopper 145 by the roller 142. From then on, both rollers are rotated as a unit by the rotation of the drive arm 163, and the wire is gripped by both rollers. It stops at position F when it reaches the wire supply line shown in the figure. As a result, the tip of the wire becomes core 1
After passing through the 000 winding insertion hole, rotate 180 degrees and insert the core 1.
This means that it is wrapped around 00. The roller 142 is braked by a spring 146, and in the process of rotation, it winds the frame pressure wire of the core while tensioning the wire. When the winding is completed, a wire holding lever 148 shown in FIGS. 11 and 19 rotates onto the core 100 to hold down the wire on the core frame and prevent the wound wire from loosening. With this, one cycle of wire winding is completed.

In the next cycle, the wire insertion device 56 first advances to grip the wire. Subsequently, the supply rollers 75 and 76 rotate to take in the wire 2, and the tip of the wire 2? Detect and stop. Therefore, the roller 14 in the position shown in FIG.
2.146 returns to the standby position shown in FIG. 18 by rotation of the drive arm 1660. Subsequently, as described above, the wire tip is reversed, inserted into the core hole, suctioned, and reversed and wound again, and thereafter the winding operation is performed in the same manner.

Note that since the wire whose base end is gripped by the gripping members 47 and 50 is removed from the wire supply line as shown by 2a in FIG. 11, there is no problem in the wire supply and winding operation. Further, the holding lever 148 is retracted before the next wire is wound.

〔Effect of the invention〕

As is clear from the above, according to the present invention, the tip of the wire pulled out from the bobbin and cut to a certain length is fixed, reversed, the other end is fed and inserted into the core, the wire is grasped, and the wire is reversed to the wire insertion side. Since the wire is transferred, the wire can be efficiently wound around the core.
