Winding device and winding method for edgewise coil

A winding device for an edgewise coil including a first coil portion having a cylindrical shape and a second coil portion having a cylindrical shape connected to the first coil portion through a connecting wire, comprising:

• a bending mechanism for bending, in a direction within a horizontal plane, a rectangular wire fed from a wire supply source in a horizontal direction;
• a feed mechanism for feeding a preset length of the rectangular wire from the wire supply source toward the bending mechanism;
• a coil guide for supporting an edgewise coil, from below, the edgewise coil being formed by alternately repeating the feeding operation for the rectangular wire by the feed mechanism and the bending operation for the rectangular wire by the bending mechanism, the edgewise coil being lowered under its own weight;
• and
• a coil-guide moving mechanism for moving the coil guide following movement of the edgewise coil by the feeding operation of the feed mechanism, and for moving the coil guide while rotating the coil guide following the movement of the edgewise coil by the bending operation of the bending mechanism,
• wherein the coil guide comprises:
• a guide column to be brought into engagement with an inner circumference of the first coil portion;
• a base plate on which the guide column stands vertically;
• a guide base which is provided on the base plate so that an upper surface of the guide base is located above an upper surface of the base plate, the second coil portion being to be placed on the upper surface of the guide base.
