A plurality of cradles 202 are provided at equally spaced positions along the circumferential direction of the cage disk 201. The number of the cradles 202 is the maximum number of the flat wire enameled wires that can be mounted on the dislocation electric wire manufacturing apparatus.

Each of these cradles 202 has a wire bobbin 203 mounted rotatably about its own axis and held by a planetary gear mechanism so as to maintain a constant horizontal position.

Each of the plurality of wire bobbins 203 is wound with a flat wire enameled wire 204, and the flat wire enameled wire 204 is sent out at the time of manufacturing a displaced electric wire.

Are passed into the transposition head 208 of the transposition mechanism 207, where they are sequentially transposed and twisted to form a transposed twisted flat enamel wire 209.

D. Kraft paper winding work The flat rectangular enamel wire dislocation stranded wire 209 obtained here is turned into a displaced electric wire by winding kraft paper or the like around the outer periphery by a kraft paper winding mechanism (not shown), and wound by a winding mechanism (not shown). It is supposed to be.

FIG. 2 is a cross-sectional view showing a state in which a plurality of flat wire enameled wires are rearranged (rearranged) in a very short length range for each fixed length, that is, a transposition work is performed. FIG.

In FIG. 2, reference numerals 204-1 to 204-7 are flat wire enameled wires.

That is, this dislocation electric wire is composed of seven elementary rectangular enameled wires 204-1 to 204-7.

Then, these seven elementary flat rectangular enameled wires 2
04-1 to 204-7 are sequentially transposed clockwise through the steps of FIGS. 2A to 2D.

First, looking at the dislocated electric wire in the state of FIG. 2 (a), the wire flat enameled wire 204-1 is located on the right side from the top.
Wire flat enamel wire 204-2, wire flat enamel wire 2
04-3 are arranged side by side, and a wire flat enamel wire 204-4 and a wire flat enamel wire 20
4-5, a wire flat enamel wire 204-6, and a wire flat enamel wire 204-7 are arranged.

Next, in the displaced electric wire in the state of FIG. 2A, the constituent flat rectangular enameled wire 204-7 is pushed in the direction A to be displaced to obtain the displaced electric wire in the state of FIG. 2B.
In other words, the displaced electric wire in the state of FIG. 2B is obtained by transposing the wire flat enamel wire 204-7 of the displaced electric wire in the state of FIG.

Next, in the displaced electric wire in the state of FIG. 2B, the constituent flat rectangular enameled wire 204-4 is pushed in the direction B to be displaced to obtain the displaced electric wire in the state of FIG. 2C.
That is, the dislocated electric wire in the state of FIG. 2C is obtained by transposing the wire flat enamel wire 204-4 of the dislocated electric wire in the state of FIG. 2B upward.

Next, in the displaced electric wire in the state of FIG. 2C, the constituent flat rectangular enameled wire 204-3 is pushed in the direction C to be displaced to obtain the displaced electric wire in the state of FIG. 2D.
In other words, the dislocated electric wire in the state of FIG. 2D is obtained by transposing the wire flat enameled wire 204-3 of the dislocated electric wire in the state of FIG. 2C to the left.

As described above, the positions of the seven elementary flat rectangular enameled wires 204-1 to 204-7 are sequentially switched. Such a dislocation is performed every predetermined length.

The dislocation operation is performed by assembling the seven flat wire enameled wires 204-1 to 204-7, that is, the periphery of the flat enameled wire dislocation twisted wire 209 shown in FIG. While being regulated by a wire guide (not shown), the seven wire flat enamel wires 204-1 to 204 from the four directions of arrow A, arrow B, arrow C, and arrow D in FIG.
-7 is sequentially applied with a dislocation force. The seven flat wire enameled wires 204-1 to 204-7 to which the dislocation force is sequentially applied in this way sequentially move in the X and Y directions orthogonal to the side surfaces of the flat wire enameled wire dislocation twisted wire 209 shown in FIG. And they are sequentially transposed by them.

The pressing position and the pressing force of the wire guide (not shown) are related to the degree of bending of the seven wire-shaped enamel wires 204-1 to 204-7 to be transposed and the quality of transposition workability. In other words, the bent shape of the flat wire enameled wire, the length of the dislocation portion, etc. are determined by the distance between the position where the dislocation force is applied to the flat wire enameled wire and the wire guide position, and the strength of the pressing force applied to the wire guide. It depends on the situation. Among these factors, the factor that greatly affects the dislocation shape is the interval between the position at which the dislocation force is applied and the position pressed by the strand guide.

That is, in order to sharpen the dislocation bending (reducing the bending angle) of the displaced wire rectangular enameled wire, it is necessary to approach the position where the dislocation force is applied and the position where the dislocation force is pressed by the guide. Conversely, in order to moderate the dislocation bending (increase the bending angle) of the displaced flat wire enameled wire, it is necessary to keep the position at which the dislocation force is applied and the position pressed by the guide away from each other.

[0033]

However, the strand guides of the conventional apparatus for manufacturing dislocated electric wires have been arranged at the same position. Further, the pressing force is adjusted so as not to cause any damage to the displaced flat wire enameled wire.

In other words, the pressing force of the wire guide (not shown) of the transposition mechanism 207 of the conventional apparatus for manufacturing a transposed electric wire as shown in FIG. 3 can be changed, but the position of the wire guide must be changed. Could not.

As described above, in the conventional dislocation wire manufacturing apparatus, since the displacement is adjusted only by adjusting the pressing force, the dislocation shape of the dislocation wire obtained by dislocation is gentle, and as a result, the dimensional accuracy of the dislocation wire decreases. was there. Furthermore, when attempting to increase the transposition work speed only by increasing the pressing force, the large pressing force causes frequent damage to the enamel coating of the flat wire enameled wire, thereby increasing the productivity of the target dislocated wire. Could not be improved. In addition, the displaced wire thus obtained has a disadvantage that the finished dimensions are large, thereby deteriorating bending resistance and coil winding workability.

For this reason, the conventional dislocation wire manufacturing apparatus cannot form an appropriate dislocation bending of the flat wire enameled wire according to the size of the flat wire enameled wire and the length of the dislocation pitch. .

The present invention has been made in view of such a point, and an object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to change the size of the displaced wire flat enameled wire and its dislocation pitch. The method of manufacturing a displaced wire and a method for manufacturing a displaced wire, which can accurately transfer a flat wire enameled wire, thereby significantly improving the dimensional accuracy, bending resistance, coil winding workability and productivity of the transferred wire. It is to provide a manufacturing apparatus.

[0038]
