るという欠点があった。However, in this conventional device, as compared with the steps (a gap A in FIG. 5) of the winding stages 7a, 7b, 7c, 7d of the front winding frame 7, the winding stages 6a, 6b, 6c,
The step difference of 6d (for example, the interval B in FIG. 5) is larger. This is the winding stage 7a, 7b, 7c of the front reel 7.
Since 7d is formed corresponding to the predetermined gap of the blade 3a of the coil insertion jig 3, it is not possible to make a large step between them, and in order to secure the required loop length of the coil, Winding stages 6a, 6b, 6c, 6d of the rear reel 6
This is because it is necessary to make a large difference in level. For this reason,
When the electric wire 1 crossed from the lower winding stage to the upper winding stage, it was easier to cross the winding frame 7 on the front side than the winding frame 6 on the rear side. When the electric wire 1 crosses the upper winding stage by the front winding frame 7, the electric wire 1 is obliquely inserted into the blade 3a of the coil insertion jig 3,
Winding failure occurs. Therefore, conventionally, when the electric wire 1 is passed from the lower winding stage to the upper winding stage, the rotation of the flyer 2 is reduced, and when the flyer 2 comes to the rear reel 6, the reels 6 and 7 are moved one stage. I tried to lower it so that I could cross it. However, since the flyer 2 is decelerated, the winding speed is reduced.

The rear bobbin 6 and the front bobbin 7 are attached to a support plate 23 fixed to the shaft 22. In this case, the front reel 7 is fixed at a position where the coil insertion jig 3 arranged below is inserted into the insertion hole 7e described above, and the rear reel 6 faces the front reel 7 and The mounting position on the support plate 23 is changed so that the distance to the front reel 7 can be adjusted. The reels 6 and 7 attached to the support plate 23 move up and down together with the support plate 23 as the shaft 22 slides up and down. Further, in the groove 7f of the front winding frame 7, a lever 24 for sequentially dropping the wound coils downward is inserted.

A, 7b, 7c and 7d are sequentially wound from the lower stage.
Then, the coils wound in each stage are sequentially dropped downward by the lever 24, thereby inserting the coils into the coil insertion jig 3. In this case, for example, the bottom winding stage 6
After the electric wire 1 is wound around a and 7a, the shaft 22 is lowered while the flyer 2 is positioned on the rear reel 6, and the reels 6, 7 are
Is lowered, and in the rear winding frame 6, the electric wire is extended to the winding stage 6b one level higher. At this time, as shown in FIG.
The portion from the winding stage 6a to the winding stage 6b above it is formed into a curved surface shape that gradually expands with a gentle curvature (large R), and the recess is formed between the electric wire 1 and the winding stage 6b above. Since the wire 6b 'is formed, the electric wire 1 can be passed over without being caught by the upper winding stage 6b. In the same manner, when the winding stages 6b to 6c and 6c to 6d are crossed, the windings can be reliably crossed without catching the upper winding stage. On the other hand, the winding stages 7a, 7b, 7c of the front winding frame 7,
Since 7d is formed to have a sharp curvature (small R) so as to stand up a corner, the electric wire 1 is prevented from crossing the upper winding stage by the front winding frame 7. Further, in the present invention, since the winding stages of the respective winding frames 6 and 7 are formed in a curved surface shape whose diameter is reduced downward, when the electric wire 1 is wound, the electric wire 1 is sequentially displaced downward. The electric wires 1 can be aligned and wound without providing the coil push rod 13 as shown in FIGS.
