When the wire 4 is attracted to a certain extent, the lower roller 156 of the second wire feeding device 113 is driven in a direction away from the upper roller 142, and then this second wire feeding device 113 is driven in the −Y direction, The above pair of rollers 14
2. Wire 4 comes off from 156. Then, the entire portion of the wire 4 that was on one side of the head chip 3 is suctioned by the first wire suction device 125. In this manner, when one end of the wire 4 is suctioned by the first suction device 125, the sleeve 171 is moved back and the wire 4 is gripped. Next, as shown in FIG. 22 (11), the first table 91 is driven in a direction away from the holder 11 and retreated to a predetermined position. At the same time, the second table 92 is driven in a direction away from the holder 11 and retreated to a predetermined position. Then, the second wire feeding device 113 is rotated 180 degrees in the opposite direction and retreated in the -Y direction to return to the initial state. Next, the first holding member 38 of the holder 11 is rotated to hold the square hole 5 of the head chip 3.
After separating from both sides of the head chip 3, the head chip 3 is rotated 180 degrees in the direction of the arrow, and then the first holding member 38 of the holder 11 is operated again to press against both sides of the square hole 5 of the head chip 3. This prevents the wire 4 wound around the wire from loosening. Next, the first wire feeding device 112 is driven in the +Y force direction to sandwich the wire 4 between its upper and lower rollers 142 and 156. Then, the cutter 164 of the first wire feeding device 112 operates to cut the wire 4.

Next, the first wire feeding device 112 is operated as shown in FIG.
It moves in the direction shown by the arrow in H), rotates 180 degrees on the way, and then moves in the direction approaching the holder 11 as shown in FIG. 22 (+). At the same time, the second wire feeding device 126 moves in the direction of the holder 11, and its sleeve 171 protrudes so that its tip is connected to the square hole of the Rad tip 3.
to face.

In this state, the upper roller 1 of the first wire feeding device 112
42 is rotationally driven to send out the wire 4, and this wire 4 is sucked by the second wire suction device 126.

When the wire 4 is attracted to a certain extent, the lower roller 156 of the first wire feeding device 112 moves away from the upper roller 142, and then is driven in the -Y direction, and the wire 4 is removed from between the upper and lower rollers 142 and 156. It comes off and is sucked into the second wire suction device 126. As a result, the wire 4 is wound twice around the herad tip 3.

In this way, the first. Second wire feeding device 112°11
3 and the wire suction devices 125 and 126, respectively, when the wire 4 is wound around the Herad tip 3 once, one cycle is completed and the state shown in FIG. By repeating such a cycle, the wire 4 is wound around the head chip 3 a predetermined number of times.

In the above embodiment, the holder 11 is arranged so that the axis of rotation for rotating the video head 1 is vertical, but the holder 11 is arranged so that the axis of rotation for rotating the video head 1 is horizontal.
may be placed. In this case, the wire feeding device 112,
Since the direction in which the slack wire 4 is blown away by the movement of the wire 113 is not horizontal but vertical, each blow tube 180 is arranged above and below the wire 4 to blow away the wire 4 and tangle it. All you have to do is to prevent it from twisting or twisting.

Further, it goes without saying that the object to be wound is not limited to the Herad chip 3 of the video head 1.

[Effects of the Invention] As described above, according to the present invention, when the wire is automatically wound around the body to be wound, the wire wound around the body to be wound can be loosened by the holding mechanism. It is now kept in a temporary state. Therefore, the wire can be wound well on the above-mentioned body to be wound without any loosening.
It is possible to prevent the occurrence of defective products.
