DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for aligning and winding wires.
The diameter of an enameled wire, a plated wire, etc.
Alignment winding method of wire material applicable to wire material of 5mmφ or more
It is about .

2. Description of the Related Art A conventional wire winding method for a wire is a winding method in which a wire is wound on a bobbin while the wires are in contact with each other or a gap winding method in which a predetermined gap is opened between the wires. Was adopted. In order to perform the alignment winding, as shown in FIG. 2, the distance between the wire 1 having the outer diameter d and the bobbin 3 having the length L of the body 32 is L = (n + 1 /
2) The relational expression of d must be satisfied. (N is the number of turns of the wire) Therefore, if the above expression is not satisfied, a gap g of about 1 to 5% of the outer diameter of the wire must be provided between the wires to obtain (n + 1/2) (d + g). was there. Here, the gap g satisfies the relational expression 0.01d <g <0.05d.

A conventional example for aligning and winding wires is shown in FIG.
3 (a), the traverse guide 2 (roll) is arranged at a position where the traverse guide 2 (roll) does not contact the bobbin flanges 31, 31, or the pulley guide 4 is arranged as shown in FIG. 3 (b). There is an example in which a wire is guided by using.

[0004]

According to the above conventional example, the traverse guide 2 and the pulley guide 4 are (d +
g), the gap g between the wires wound around the bobbin body 32 is not accurately maintained even if the wire is accurately moved at the pitch of g).
Accurate aligned winding could not be performed. In pursuit of this cause, the position of the traverse guide (roll or pulley) is far away from the body of the bobbin, so the moving distance of the traverse guide and the moving distance of the part where the wire is wound around the bobbin body are different. It turned out to be.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and to form an aligned winding of a wire capable of forming a predetermined gap between the wires when winding the wire on a bobbin. It is to provide a method .

[0006]

According to the present invention, there is provided a method of aligning and winding a wire rod on a bobbin body by means of a traverse guide traversing at a predetermined pitch between both flanges of a bobbin in parallel with a bobbin rotation axis. In the method of aligning and winding the wire, the wire length of the bobbin with respect to the wire having the outer shape d, the number n of the wire wound on the circumference of the body and the gap g between the wires are set.
Satisfies the relational expression of L = (n + 1/2) (d + g)
On the bobbin body and close the wire to the winding direction
Wind the wire with the auxiliary guide extending along
By traversing to the position just before the touching part
While leaving a gap of 1-5% of the wire outer diameter between the wires.
And performing et regular winding. According to this method, when the wire is wound around the bobbin body to form the first layer, the wire is traversed until immediately before the wire comes into contact with the body.
The gap between lines can be
It will be possible to open exactly by the numerical value .

[0008]

FIG. 1 shows a preferred embodiment of an apparatus for carrying out the method for aligning and winding wires according to the present invention. Reference numeral 1 denotes an enameled wire serving as a wire rod, which is wound around the body 32 of the bobbin 3 via the traverse guide 2 (roll) → the auxiliary guide 5 (roll) while forming a gap.

Thus, the traverse guide 2 is provided on the bobbin 3
Guides the enamel wire 1 from a position where the enamel wire 1 does not hit the flanges 31 of the bobbin. However, one auxiliary guide 5 can traverse the bobbin body 32 at a position immediately before the portion where the enamel wire is wound and in contact with the bobbin body 32. If the traverse guide 2 and the auxiliary guide 5 are traversed in a fixed relationship, they can be aligned and wound with a fixed gap.

The auxiliary guide 5 is supported by a cylinder 6 so as to be able to advance and retreat with respect to the bobbin on a tangent to the bobbin body 32. Therefore, after the auxiliary guide 5 is retracted by the cylinder 6 so that the auxiliary guide 5 does not hit the flanges 31 of the bobbin, the second and subsequent layers of wire may be wound.

[0011]

As described above, the winding method of the present invention as described above.
According to the method , in addition to the traverse guide, an auxiliary guide that guides the bobbin body close to the traverse guide is used, so that the aligned winding with the gap of the wire rod can be accurately performed according to the traverse pitch.
