DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for winding a wire such as an ultra-fine rectangular copper wire.

[0002]

2. Description of the Related Art Conventionally, as a wire winding device of this type, as shown in FIG. 6, a bobbin B is wound and rotated, and the bobbin B or traverse T is reciprocated in the axial direction, and is sequentially fed via a guide roller R. There is known a structure in which an incoming wire W is wound around a bobbin B in cooperation with the traverse T.

[0003]

However, in the case of the conventional structure described above, for example, when the wire is a round wire, this does not occur so much. However, when the cross section is a rectangular wire having a rectangular cross section, the shape is a factor. As shown in FIG. 7, the wire W may be wound up while riding on the wire, and therefore, in the case of a flat wire, especially the aligned winding is required. There is an inconvenience that twisting or the like occurs.

2 is a traverse, 3 is a guide member, and 4 is a separating mechanism. In this case, a moving table 5 is provided on a machine table (not shown) so as to be reciprocally movable in the axial direction of the bobbin B by a motor (not shown). A swing shaft 6 is swingably supported on the movable base 5 by a bearing base 7, a gear 8 is fixed to the rear end of the swing shaft 6, and a swing motor 9 is mounted on the movable base 5 for swinging. A gear 10 meshing with the gear 8 is fixed to the main shaft of the motor 9, while a base end of the swing arm 11 is fixed to a tip of the swing shaft 6, and a straddle 12 is fixed to a tip of the swing arm 11. And the traverse 2 is attached to the swing arm 11.

In this case, the guide member 3 includes a pair of guide plates 3a.
3b, each end of which is attached to the straddling portion 12 of the swing arm 11 by an attachment shaft 13. A gap between the pair of guide plates 3a and 3b is slightly larger than the outer diameter of the wire W. S is formed, and a wire W, which is sequentially sent from the wire drawing machine or the like to the traverse 2 and the bobbin B, is inserted through the passing gap S and is arranged, and a pair of guide plates 3a is provided.
-It is configured to guide the wire W in a sandwiched state by 3b.

Reference numeral 14 denotes a detection mechanism, in which a photoelectric sensor is used, and a light projector 14a and a light receiver 14b are arranged to face the straddle section 12, and the light transmitter 14a and the light receiver 14b
Is detected by the wire L wound around the bobbin B being interrupted by the wire L that reaches the bobbin B.

In this case, the swing motor 9 rotates in response to the winding state signal from the detecting mechanism 14, and the gear 8
The swinging shaft 6 rotates through the gear 10 and the swinging arm 6 swings away by the rotation of the swinging shaft 6 to maintain a constant distance between the guide member 3 and the wound wire W. It is configured to

In this embodiment, the wire W is sequentially fed to the rotating bobbin B as shown in FIG. Will be wound up by the cooperative action of.

At this time, a pair of guide plates 3a.
3b, the wire W from the traverse to the bobbin is guided in a sandwiched state, so that the wire W
Can be wound in an aligned state, and even if the wire W is a flat wire, occurrence of bending or twisting can be suppressed, and a good winding operation can be performed.

Further, at this time, the detecting mechanism 14 sequentially detects the winding state of the wire W, and receives a signal from the detecting mechanism 14 to follow the winding state of the wire by the separating mechanism 4 so that the guide member 3 is gradually increased. Since it moves outward, it is possible to not only prevent contact between the guide member 3 and the wire W, but also to achieve a good wire guide operation.

The present invention is not limited to the structure shown in the above embodiment. For example, in the above embodiment, the bobbin B is fixed and the traverse 2 reciprocates in the axial direction. The present invention can also be applied to a structure in which the traverse 2 is fixedly arranged and the bobbin B reciprocates in the axial direction.
