Further, a belt 34 is applied to a pulley 31 provided on the fryer 24 and a pulley 33 of a motor 32 fixed to an elevating plate 25, and the flyer 24 is rotated around the group of winding frames 11 to wind the electric wire 23.

Reference numeral 35 indicates a pulley for guiding the electric wire 23 provided on the mounting board 5.

A cylinder 36 is also suspended on the side opposite to the fryer on the mounting board 5, and upper and lower plates 39 are attached to the piston rod 37 on which a large number of coil insertion guide plates 38 are arranged and suspended in a circular manner. A cylinder 41 for raising and lowering the molding push piece 40 that fits into each coil insertion guide plate 38 is provided, and the molding push piece 40 is fixed to the piston rod 42 thereof.

Reference numeral 43 denotes a guide tube for the upper and lower plates 39 suspended from the mounting board 5, into which the rods 44 erected on the upper and lower plates 30 enter.
A piston rod 48 of a cylinder 47 attached to the periphery of the turntable 4 is fixed to an L-shaped piece 46' suspended from the entrance/exit plate 46, and the winding frame 11 is slightly moved up and down.

The coil forming guide plate 10 has an upper edge 49 curved in an arc shape and has a stepped portion 15 below it, and the coil insertion guide plate 38 has a lower edge 50 curved in an arc shape and has a stepped portion 51 on the inner sealing edge. It is.

Next, the operating state of the present invention will be explained.

First, turn the turntable 4 to remove the winding frame 1 without winding.
1 under the flyer 24, and the winding frame 11 with completed winding.
is positioned below the coil insertion guide plate 38 group.

On the other hand, the flyer 24 is lowered to wind the electric wire 23 around the winding frame 11 in series, and while the flyer is rotated, the flyer 24 is gradually raised again while winding.

Then, the winding wire 23 is cut when winding is completed.

After completing the winding, the winding frame 11 located directly below the group of coil insertion guide plates 38 is lowered by the upper and lower plates 39, and the coil insertion guide plate 38 enters inside the coil 23' as shown in FIG. The step 51 matches the step 15 of the coil forming guide plate 10, and then the armature 14 rises and fits into the steps 15 and 51.
