[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire winding device for winding a wire supplied to a twisting machine around a bobbin.

[0002]

2. Description of the Related Art A tubular or basket type twisting machine is one in which wire rods are supplied from a plurality of bobbins and twisted together. For example, in a tubular twisting machine Y as shown in FIG. 1, the wire rods W are pulled from each bobbin 1 and rewound, and the wire rods W to which the tension has been applied pass through the eye plate 2 and are twisted by the dice 3. A brake is applied to the rotating bobbin 1 to apply tension to the wire W.

[0003]

However, if the starting end of the wire wound around the bobbin separates from the bobbin, the wire cannot be tensioned, and the tension of the wire cannot be adjusted by the twisting machine. Therefore, it is impossible to use the wire rod between the die and the bobbin when the wire rod is separated, and the bobbin located farther from the die is wasted more wire rods.
That is, since the starting end of the wire rod is directly fixed to the bobbin, the above-described adverse effects occur.

In view of the above, the present invention has an object of providing a wire rod winding apparatus and a wire winding method capable of effectively using a wire rod wound around a bobbin.

[0006]

According to the means for solving the problems of the present invention, the lead wire L different from the wire W is wound around the empty bobbin 11, and then the lead wire L and the starting end of the wire W are connected to each other. The wire W is wound around the bobbin 11.

Therefore, a bobbin 11 for winding a wire rod rotatably supported by the cradle 10, a bobbin drive means 12 for rotating the bobbin 11, and a lead wire L different from the wire W are guided to the bobbin 11. Guiding means 13, a lead wire winding means 14 for fixing the tip of the lead wire L to the bobbin 11 and winding it, a cutting means 15 for cutting the lead wire L, and a wire W for winding the lead wire L. The connecting means 16 for connecting to the starting end is provided.

[0008]

In the above means for solving the problems, when the empty bobbin 11 is mounted on the cradle 10, the guide wire 13 guides the lead wire L to the peripheral surface of the bobbin 11 and the lead wire L is fixed to the bobbin 11. Then, by rotating the bobbin 11, the lead wire L is wound around the bobbin 11. Next, the lead wire L is cut by the cutting means 15, the tip of the wire rod W is connected to the lead wire L by the connecting means, and the bobbin 11 is rotated to wind the wire rod W.

When the bobbin 11 around which the lead wire L is wound in this way is used in a twisting machine, the lead wire L is unwound even if the wire material W is unwound and all disappears from the bobbin 11, so that the wire material W is rewound. Is in a tensioned state, and the terminal of the wire W can be used.

In this way, the end portion of the lead wire L is bent, and the bent lead wire L is fitted to the tip of the wire material W by the clip 90 to connect the lead wire L and the wire material W. Moreover, by bending the lead wire L,
Since a ring is formed on the lead wire L when they are connected, even if the wire rod W and the lead wire L slip at the connecting portion, the ring becomes a dumb shape and does not unwind, and a strong connection can be performed.

After the connection between the lead wire L and the wire material W is completed, the twisting machine is normally operated, and the wire material W twisted twice is wound around the bobbin 11. When the wire W is fully wound on the bobbin 11, the suction device 82 that has adsorbed the adhesive tape T descends, the wire W is fixed to the bobbin 11 by the adhesive tape T, and the wire chuck 108 grips the wire W. The wire W is cut by the nippers 107. Then, the fully wound bobbin 11 is taken out, the empty bobbin 11 is mounted on the cradle 10, and the lead wire L is wound again as described above.

When the bobbin 11 around which the lead wire L is wound in this way is used in the twisting machine Y, the lead wire L is unwound even if the wire material W is unwound and the bobbin 11 is completely removed. As described above, the wire W can be maintained in a tensioned state, and the wire W can be effectively used until the connecting portion between the wire W and the lead wire L comes close to the eye plate.

The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. For example, a tape may be used instead of the clip as a means for connecting the lead wire and the wire. Also, the material of the lead wire is not limited to polypropylene, but may be a thread, a soft wire, or the like, and the means for fixing the lead wire to the bobbin may be fixed to the flange of the bobbin with adhesive tape, hooked on the flange, or attached to the wheel It may be wound around the bobbin and then wound around the bobbin by guiding it to the peripheral surface of the bobbin.
