Then, the wire insertion device 56 consisting of the second supply rollers 75, 76 and the base 77 is rotated counterclockwise around the sleeve 66, and is reversed and moved to the chain line position E in Figure @10. As a result, the small diameter side of the cap 77 faces in the wire supply direction, and the tip of the cap 77 approaches and opposes the winding hole of the core 1000, which has been placed on the wire supply line in advance.

Subsequently, the motor 85 reverses counterclockwise, and the drive roller 9 comes into contact with the driven roller 80.
2 is rotated counterclockwise in FIG. 10, and the tip of the wire 2 is inserted into and passed through the hole of the core 100. At this time, the tip of the wire 2 is guided to the base 77, and the small diameter side of the wire 2 is guided to the core 1.
Since it faces the winding hole of core 1000, even if the wire 2 is slightly bent, it will be fed over the tapered surface and the wire 2 will be reliably inserted into the winding hole of core 1000.

Although not directly related to the present invention, the mechanism constituting the winding device of this embodiment will be described below.

First, a wire holding device that holds the wire 2 through the core 100 will be described with reference to FIGS. 15 to 17. This wire holding device consists of two guide rails 102 fixed to a frame 101 parallel to the wire 2 supply line.

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 a pair of gripping rollers 116 and 114 are released at the tip of the holding pipe 105.
is pushed open and stopped at a position where the holding pipe 105 approaches 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 drive roller 920, and its tip is inserted into the holding pipe 105 and held there. At this time, a vacuum pump (not shown) is activated to apply vacuum through the holding pipe 105, thereby making it possible to insert the wire 2 into the winding hole of the core 100 more reliably. wire 2
When the movable table 104 is inserted a predetermined length, the movable table 104 begins to retreat. The holding pulp 105 is held by the gripping rollers 116, 114
When the wire is released rearward from the wire, the gripping rollers 116 and 114 grip the wire by the biasing force of the spring 115. At this point, the vacuum suction is stopped, and the moving table 104 is further retreated, so that the wire gripping roller device 108 is retracted, and the wire 2 is gripped by the gripping rollers 113 and 114, and the core 1 is
The wire will be pulled out from the winding hole 00. 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 move the lever 1 to the retreating end shown in FIG.
The cam surfaces 122 and 123 of 11 and 112 are the rollers 120.
121, the levers 111, 112 open and the first gripping rollers 113, 114 move away to release the wire. 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 moved back by opening the second supply roller 76 and the movable cap 77b as the push lever 96 shown in FIG. is reversed and returned to its original position.

Next, the reversal winding method 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 161 is rotatably attached to a frame 160, and is reciprocated by power transmitted to a gear 162. axis 161
A driving arm 166 is fixed to the end of the frame 160, and a driven arm 134 is attached to the inside of the frame 160 so as to be rotatable on a shaft 131. A support shaft 165 extending perpendicular to the wire is fixed to the tip of the drive arm 163, and another support shaft 166 is fixed to the tip of the driven arm 134.
The ends of are fixed. Links 137 and 138 that connect to each other are rotatably fitted to both support shafts 135 and 136, and their tips are connected to each other by a shaft 140.
The torsion spring 141 wound around 0 is attached to both support shafts 1
35 and 136 are urged toward each other. The support shafts 135 and 136 extend to the supply line of the wire 2, and rollers 142.
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, 143 are separated.

Next, the operation will be explained. In Figure 15, wire 2
When the gripping rollers 113 and 114 pull out the wire 2, the rollers 142 and 143 are in the position shown in FIG. 15 and are waiting above and below the pulled out wire 2. Following the completion of the withdrawal, the drive arm 163 begins to rotate counterclockwise in FIG. 18, and the roller 142 comes into contact with the wire 2.
lift this up. When the roller 142 hits the roller 143, the wire is gripped by both rollers, and the roller 143 is lifted up 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 1330, and as shown in FIG. It stops at position F when it reaches the wire supply line. 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, the wire is wound around the core frame while tensioning the wire. When the winding is completed, the wire restrainer <-148 shown in FIGS. 2 and 19 rotates onto the core 100 to restrain the wire on the frame of the core 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, detect the tip of the wire 2, and stop. Therefore, the rollers 142, 143 located at the positions indicated by F in FIGS. 10 and 18 return to the standby position shown in FIG. 18 by rotation of the drive arm 166. 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 held by the base end fixing device 49 has come off the wire supply line as shown in FIG. Further, the holding lever 148 is set at 5 so as to be retracted before the next wire is wound and attached.

〔Effect of the invention〕

As is clear from the above, according to the present invention, it is possible to automatically pull out the wire with a bobbin and cut it to a certain length, and also to feed the wire efficiently without causing any slack in the wire. It is something that can be done.
