Abstract
A rotary body including a drum and a wire support member winds a wire by rotation. A spacer is provided on the rotary body and is displaceable to a first position and a second position in the rotary body. When the spacer is in the first position, the wire is wound on the rotary body not via the spacer, and hence the wire is wound with the first diameter. When the spacer is in the second position, position, the wire is wound on the rotary body via the spacer, and hence the wire is wound with a second diameter larger than the first diameter.
Claims3
A wire winding device comprising:
- a rotary body that winds a wire by rotation;
- and
- a spacer provided on the rotary body and displaceable to a first position and a second position in the rotary body, wherein
- when the spacer is in the first position, the wire is wound on the rotary body not via the spacer, and hence the wire is wound with a first diameter,
- when the spacer is in the second position, the wire is wound on the rotary body via the spacer, and hence the wire is wound with a second diameter larger than the first diameter,
- the rotary body includes a support member including a U shape holding and supporting the wound wire in a direction parallel to a rotary shaft of the rotary body,
- when the spacer is in the first position, the wire is wound inside the support member not via the spacer,
- when the spacer is in the second position, the wire is wound inside the support member via the spacer,
- the support member including the U shape includes a pair of walls holding the wire in a direction parallel to the rotary shaft of the rotary body, and a bottom supporting the wire from a side of the rotary shaft of the rotary body,
- the pair of walls includes a movable side wall and a fixed side wall,
- the movable side wall is displaceable from a third position holding the wire to a fourth position different from the third position,
- when the movable side wall is in the fourth position, the wire wound on the rotary body can be removed from the rotary body by moving in a direction parallel to the rotary shaft of the rotary body,
- the spacer has a top surface and a bottom surface opposed to the top surface,
- the top surface support the wire when the spacer is in the second position, and
- the bottom surface abuts against the bottom of the support member when the spacer is in the second position.

A wire winding device comprising:
- a rotary body that winds a wire by rotation;
- a spacer provided on the rotary body and displaceable to a first position and a second position in the rotary body;
- an additional spacer provided on the rotary body and displaceable to the first position and the second position in the rotary body;
- a rotary shaft coupled between the spacer and the additional spacer at proximal ends of the spacer and the additional spacer;
- and
- a rod member coupled between the spacer and the additional spacer at distal ends of the spacer and the additional spacer, wherein
- when the spacer is in the first position, the wire is wound on the rotary body not via the spacer, and hence the wire is wound with a first diameter,
- when the spacer is in the second position, the wire is wound on the rotary body via the spacer, and hence the wire is wound with a second diameter larger than the first diameter,
- the rotary body includes a support member including a U shape holding and supporting the wound wire in a direction parallel to a rotary shaft of the rotary body,
- when the spacer is in the first position, the wire is wound inside the support member not via the spacer,
- when the spacer is in the second position, the wire is wound inside the support member via the spacer,
- the support member including the U shape includes a pair of walls holding the wire in a direction parallel to the rotary shaft of the rotary body, and a bottom supporting the wire from a side of the rotary shaft of the rotary body,
- the pair of walls includes a movable side wall and a fixed side wall,
- the movable side wall is displaceable from a third position holding the wire to a fourth position different from the third position,
- when the movable side wall is in the fourth position, the wire wound on the rotary body can be removed from the rotary body by moving in a direction parallel to the rotary shaft of the rotary body, and
- when the spacer and the additional spacer are in the second position, the fixed side wall is located between the spacer and the additional spacer and is located between the rotary shaft and the rod member.
