It is configured so that the wire 4 is continuously wound around the winding form 151 at a fixed position according to the state.

Next, the operation will be described. First, the wires 4, 4 taken out of the drums 121, 121 of the wire feeders 120, 120 are sent out to the respective guide rollers 135, 135 on the base 170 through the sensors 125, 125, respectively, and the wire rods 4, 135 are fed by the respective guide rollers 135, 135. 4,
4 is sandwiched from above and below, and the wires 4 and 4 are guided to the downstream side in a horizontal state. In this process, first, the windings of the wires 4, 4 on the drums 121, 121 are corrected by sandwiching the wires 4, 4 from the left and right directions by the brake roller 132 and the pressing roller 133. Next, each wire 4,4 whose winding habit has been corrected
Is sent to the respective reverse distortion rollers 140, 140 via the respective levelers 130, 130 and the fixed roller 134, and is applied to the respective wire rods 4, 4 by the respective reverse distortion rollers 140, 140, and is sent to the winding form 151. The starting ends of the wires 4, 4 are fixed to a predetermined number of the winding form 151 by a clamper (not shown). After that, the wire rods 4 and 4
Starts to be wound around the winding form 151.

The winding of the wires 4 and 4 by the winding form 151 is performed as follows. First, when the winding rotation driving motor 153 of the winding machine 150 rotates, the winding 151
Is counterclockwise from the state shown in FIGS. 8 and 9 (FIGS. 8 and 10).
(In the direction indicated by the arrow in FIG. 3) in the horizontal direction to start winding the wires 4 and 4, and the motor 157 for moving the winding machine main body.
Is driven to gradually move the winding machine main body 154 in the direction indicated by the arrow, and the winding position of the wires 4, 4 by the winding form 151 is always maintained at the fixed position P. That is, as the distance between the winding position of the wire 4 and the center O of the winding form 151 gradually increases with the horizontal rotation of the winding form 151, the winding machine main body 154 moves in the direction indicated by the arrow to form the winding form. The take-up position 151 is always kept at the fixed position P without being changed. Then, when the winding die 151 is horizontally rotated counterclockwise by 90 ° to the state shown in FIGS. 10 and 11, the distance between the center O of the winding die 151 and the winding position (fixed position P) is the longest. Further, as the winding form 151 rotates, the winding machine main body moving motor 157 is driven in reverse, and the winding machine main body 154 moves in the direction indicated by the arrow and returns to the position shown in FIG. Is always kept at the fixed position P. At this time, the brake roller 132 is driven to
1, while applying a constant tension to the wire 4 while applying a reverse strain to the wire 4 by the reverse distortion roller 140, and suppressing the springback or the like of the wire 4 by the reverse strain, the wire 4 is moved to FIG. As shown in FIG. When the winding of the wires 4 and 4 is repeated as described above and the wires 4 and 4 are superimposed and wound on the winding form 151, the motor 157 for moving the winding machine main body is driven, and the winding machine main body 154 is moved by the arrow. Move to the indicated direction and set the winding position to the fixed position P
To keep. The coil 160 wound in a predetermined number of turns in this way is solidified by baking in an insulating varnish or the like in the next step.

The above-described control of the winding operation is performed according to a flowchart shown in FIG. That is, the former 1
Winding of the wire 4 by 51 starts (step 1).
At the same time, the counting of the number of windings of the wires 4, 4 is started (step 2). After that, the winding rotary drive motor 15
3 is driven (step 3), and the amount of rotation of the winding form 151 is measured by an encoder with this drive (step 4).
The rotation amount is calculated (step 5). At this time, if the amount of rotation is not recorded, the process returns to step 3; if the amount of rotation is recorded, the process proceeds to step 6. If the amount of rotation of the winding form 151 matches the set value of the winding amount in this step, the form rotation is performed. The driving motor 153 is stopped (Step 7), and the winding of the coil 160 is completed (Step 8). In addition, the winding machine main body moving motor 157 that runs in parallel with the above-mentioned operation is similarly driven in accordance with steps 3A, 4A, and 5A to control the winding machine main body 154.

As described above, according to the present embodiment, the winding machine main body 154 is moved with respect to the reverse distortion rollers 140, 140 installed at fixed positions to set the winding positions of the wires 4, 4 at the fixed positions. Since they did not move from P, the levelers 130, 130 and the reverse distortion rollers 140, 1
No need to lift heavy equipment like 40,
A high-load motor used for the lifting and lowering is not required, so that the apparatus can be manufactured at lower cost as compared with each of the above embodiments, and the reverse distortion rollers 140, 140 and the former 1
51 allows the elliptical coil 160 (see FIG. 12) to be bent at an accurate curvature, and the reverse distortion roller 140 suppresses springback or the like to eliminate drum-shaped swelling, thereby causing variations at each turn. And a stable quality elliptical coil 160 can be formed. Also, according to the present embodiment, the coil 160 after the winding
Is in the horizontal direction, so that the coil 160 can be easily unloaded, which is suitable for line automation.
