Next, the vacuum pump (182) is driven to generate suction force in the first suction device (125), and the upper roller (c) of the six arms is driven to rotate, causing the upper roller (c) and the lower roller to rotate. A wire (11) held between the rollers 0 and 0 is fed out for a certain length. The wire (4) fed out by it is connected to the head chip (
8) through the square hole (5) and into the pipe (170) 173.
As shown in FIG. 0, the sleeve (171) of the wire suction device (125) is moved to its retracted position, thereby clamping the wire (4) with the elastic body (174). Thereafter, the first wire feeding device (112) is moved together with the wire suction device (125) to its retracted position, and the head tip (

The wire (4) is wrapped once on the side. In addition, in this second position, the head chip (8) is in a state in which the central axis of the square hole (5) is located parallel to the guide tray Jv (1). and the first holding member (to) of the holding means 7 and 0;
is rotated toward the head chip (3), and its elastic body (end) presses against both sides of the square hole (5) of the head chip (3) to prevent the wire (4) wound here from loosening. . Subsequently, as shown in FIG. 24(c), after the first wire feeding device (112) moves from its first position to its second position with the clamping body (155) open, Clamping body (155
) is in the closed state, and the wire (4) is suctioned by the upper 1:1-5T (142) and lower roller (156) fl! !
'(112) The side ends are clamped. Next, the cutter (164) of the wire feeding device R (112) is activated to cut the wire (4). When the wire (4) is cut, as shown in FIG. , During this time, the wire feeding device (125
) is rotated counterclockwise in FIG. 24(6).

Also, at this time, the nozzle (181) of the blow pipe (180)

The slack wire (4) between the wire feeding device (112) and the wire feeding device (112) is blown away in the horizontal direction.

Therefore, even if the wire (4) becomes slack due to the first wire feeding device (112) approaching the holding means α, the wire (4) is prevented from becoming tangled or twisted. be done. As the first wire feeding device (112) moves, the front end of the wire (4) cut by the cutter (164) of the first wire feeding device (112) is moved as shown in FIG. As shown in
It faces the square hole of the head chip (8). Simultaneously with the movement of the first wire feeding device (112), the second table 04 is driven by the drive motor ee and moved in the direction approaching the holding means 0, and the second table 04 is moved by the X-direction cylinder (128). , the second suction device (126) is driven, and the tip of its sleeve (171) faces the square hole (5) of the head tip (3). In this state, the upper roller (142) of the first feeding device (112) is rotationally driven to feed the wire (4) toward the head chip (3). At the same time, the vacuum bonder (182) is activated to generate suction force in the sleeve (171) of the second suction device (126). Alternatively, the wire (4)
from the feeding device (112) of the head chip (8) to the square hole (
5) and is sucked into the second suction device (126).

When the wire (4) is attracted to a certain extent, the lower roller (156) of the first wire feeding device (112) is driven in a direction away from the upper roller (142), and then the first
The wire feeding device (112) is moved from the second position to the first position, and the wire (4) is removed from the pair of rollers (142) (156). Then, the portion of the wire (4) on the right side of the head tip (3) is completely sucked by the second wire suction device (126).

In this way, one end side of the wire (4) is connected to the second suction device (
126), the sleeve (171) is moved to the retracted position and the wire (core) is gripped by the elastic body (174).Next, as shown in FIG. e is driven in the direction away from the holding means α, and the second feeding device (113) and the second suction device (126) are moved to the retracted position. ) is the head chip (3) and the second
and the suction device fil (126).

Moreover, at the same time, the first table 01 is moved to the holding means 0.
The first feeding device (112
) and suction equipment! (125) is retracted to a predetermined position. During this time, the first feeding device (112) is rotated 180 degrees in the opposite direction to the previous one and returned to its initial position. Subsequently, after rotating the first holding member (to) of the holding means αD and separating it from both sides of the square hole (5) of the head chip (8), the holding means (b) is attached to the head chip (8). 1 counterclockwise from the second position shown to the first position.

actuate to insert the elastic material (A) into the square hole (
5) to prevent loosening of the wire (4) wound here. Next, as shown in FIG. 24 CI), the second wire feeding device (113) is moved from its first position to its second position, and the upper and lower rollers (142),
156), the front end of the wire (4) is held between them. Then, the cutter (164) of the second feeding device (113) is activated and the wire (4) is cut between the feeding device (113) and the second suction device (126). The second wire feeding device (126) is then moved to its forward position and rotated 180 degrees during the movement.

Accordingly, as shown in FIG. 24 σ), the front end of the cut wire (4) faces the square hole (5) of the head chip (3). Also, the first wire feeding device 9 (112) and the first wire suction device (125) are moved to their forward positions, and the sleeve (171) of the suction device protrudes so that its tip faces the square hole (5). do. In this state, the upper loaf (142) of the second wire feeding device (113) is rotationally driven to feed the wire (4).
) is sucked into the first wire suction device (125) through the square hole (5) of the head chip (8).When the wire (4) is suctioned to a certain extent, the second wire under-suck device (113)
), the lower roller F (156) is the upper roller (142)
After being moved in the direction away from the feeding device (113)
is moved to the first position. Thereby, the wire (4)
is removed from between the rollers (142) and (156) and is sucked into the first wire suction device (125). As a result, a wire (4 wires) is attached to one side of the square hole (5
) has been wound twice. By repeating the above-described cycle, a predetermined fixed number of wires (4) are wound around the head chip (3).

Thus, after winding the wire (4) on the negative side of the square hole (5), when winding the wire (4) on the other side of the square hole (5), the wrinkle prevention mechanism (83) is used. Activate. That is, the air cylinder (184a) is operated to perform the operation m a(
184C). Then, the suppression axis (184d)
contacts the wire (4) and pushes down the contacted wire (4). By rotating the holding means 0 in this state, the wire (4) reaches the lower end of the other side of the square hole (5). Therefore, it is possible to prevent the "crossing line" from crossing the square hole (5) in the middle. At this time, the suppression axis (184 east) shown by the imaginary line in FIG. is set so that it reaches in a straight line from the highest position on the negative side of the square hole (5) to the lowest position on the other side.

As described above, according to the winding method of this embodiment, the wire (6) can be automatically wound around the head chip (3) without causing any winding defects.

Therefore, work efficiency and yield can be significantly improved, and the burden on workers is significantly reduced.

In addition, as shown in FIG. 25, the crimp line prevention mechanism (183) has a bifurcated U-shaped support (184e) attached to the tip of the operating shaft (184C), and this support (1
Suppression shaft (184d), (184d) at the tip of 84e)
Even if the wires (6) are connected in parallel to each other and the wires (6) are pressed on both sides of the head chip (8), the same effect as in the above embodiment can be obtained. Further, the crimp line prevention mechanism (183) shown in FIG. 1 may be installed separately on both sides of the head chip (8). Furthermore, the crossing wiring prevention mechanism (183) is not applied when the wire (4) on the other side is transferred from the negative side of the square hole (5), but in the wire winding on the negative side of the square hole (5) immediately before this transition. It may be activated. By doing so, the wire (4) can be wound without protruding above the head chip (3). Furthermore, in the above embodiment, the wire (4) is wound around the video head (1) as it rotates, but the video head (1) is fixed and the wire (4) side is rotated. It can also be applied to a winding method of winding the wire (4) around the video head (1). In this case, the pressing shaft (18
As a material corresponding to 4d), a half-ring shape is preferable. In addition, as the body to be wound, the head chip (8)
Of course, this is not limited to.
