Wire winding device and wire winding method

A wire winding method for performing a wire winding by using a device having:

• a rotary plate rotationally driven by a driving mechanism;
• a pair of columnar members respectively provided on the rotary plate so as to be movable along a straight line, the straight line extending orthogonal to a rotation center axis of the rotary plate;
• winding cores respectively attached to the pair of columnar members;
• and
• a holding mechanism configured to change and hold respective distances from the rotation center axis of the rotary plate to the pair of columnar members, the holding mechanism having:
• a movable plate provided on the rotation center axis of the rotary plate, the movable plate being movable along a direction of the rotation center axis of the rotary plate,
• a pair of wedge members having inclined surfaces facing the pair of columnar members, the pair of wedge members being provided on both side surfaces of the movable plate such that the rotation center axis of the rotary plate is positioned between the pair of wedge members, and
• a wedge moving mechanism configured to move the pair of wedge members together with the movable plate along the direction of the rotation center axis of the rotary plate;
• the method comprising:
• a step of adjusting a gap distance between the pair of columnar members, and
• a subsequent step of, while holding respective distances from the rotation center axis of the rotary plate to the pair of columnar members so as to become same with each other by the holding mechanism, winding a wire rod around the winding cores by rotating the rotary plate, the winding cores being rotated together with the pair of columnar members.
