Function> The head is mounted on the mounting device, and the position of the head is determined by the positioning means.

Grip the wire with the wire gripping hand of the wire feeding device,
The wire gripping hand moving mechanism moves the wire gripping hand a predetermined distance toward the mounting device. The insertion device is
It is moved in front of the wire gripping hand by the conveyance device, descends, and grips the wire with the rollers. Cut the tip of the gripped wire. The insertion device is moved to the position of the loading device by the transport device, and the wire tip is directed toward the head.

The insertion device 3o is moved in front of the wire gripping hand 21 (in the direction of arrow B in FIG. 1) by a ball screw 44 and a guide shaft 45 when the moving motor 46 of the conveyance device 40 is driven, and is moved by air for vertical movement. It is lowered by the cylinder 42 and grips the wire 1 by the rollers 35,36. Next, the wire 1 is cut between the insertion device 30 and the wire gripping hand 21 using a cutter (not shown). Thereafter, the insertion device 30 is moved to the position of the loading device IO by the transport device 40, and the wire tip is directed toward the head 80.

The roller 35.3 is then driven by the roller drive motor 37.

Then, the wire 1 is sent out by the rollers 35, 36, and the air inlet 303 of the air insertion block 33, 34 is fed out.
The compressed air supplied to the is injected from around the tip of the wire 1 in the direction of movement of the wire 1 through the differential user section 300 and the differential user section outlet 304, and this air flow causes the wire 1 to be inserted into the core hole 83 to perform the suction operation. It is sucked into the suction nozzle 51 as shown in FIG.

Next, the suction nozzle 51 is slid one step by the one-step sliding drive source 52, and the return hand gripping hand 7
1, the wire l is held between the head 80 and the tip of the suction nozzle 51 as shown in FIG. 1θ.

After this, the insertion device 30 drives the cylinder 39 to release the gripped wire l. The suction nozzle 51 is slid two steps by the two-step sliding drive source 53, and the return hand gripping hand 71 is moved in the pull-out direction. Then, by driving the pad opening/closing drive source 62, the return hand gripping hand 71 and the head 80 are moved as shown in FIG.
The wire l between them is gripped by the positioning pad 61.

Thereafter, the positioning pad 61 is lowered one step by the first step sliding drive source 63 as shown in FIG. 12, and the return hand gripping hand 71 is rotated in the direction of arrow C by the return hand gripping hand rotation motor 73. As a result, the wire 1 is inserted into the slit 84 of the head 80 through the ends of the head cover 15 closed by the drive source for opening and closing the head cover. The head cover 15 is provided to prevent the wire l from being pulled out from the slit 84 at this time. However, when the return hand gripping hand 71 is rotated, the insertion device 30 is released upward by the vertical movement air cylinder 42 of the conveyance device 40. Wire l is slit 84
After the wire 1 is inserted into the wire, the return hand moving motor 75 drives the ball screw 74 to move the wire 1 held by the return hand gripping hand 71 in the direction of the wire feeding device 20, thereby winding one turn. End the line.

The winding after the second turn is as shown in Figure 13.
- The wire 1 held by the return hand gripping hand 71, that is, the head 80 and the return hand gripping hand F7
The rollers 35 and 36 of the insertion device 30, which are lowered by the vertical movement air cylinder 42, grip the wire 1 which is stretched between the wire 1 and the core hole 8 of the wire 1 described above.
By repeating the insertion into the slit 84 and the insertion into the slit 84, the winding work can be performed.

This completes the winding of the double azimuth type core onto the first channel. Such winding is also carried out to the second channel to complete one head.

As described above, according to this embodiment, since the winding to the head 80 can be performed mechanically, the efficiency of the winding work can be improved.
