Winding device for wire material with rectangular section
View Patent ↗Wire winding is performed while a guide member is regulating a winding position of a regular-square wire (for example, while moving the wire member in an axial direction in accordance with the number of winding (turns) of the rectangular cross section wire member) such that a side surface of the regular-square wire already wound on an outer periphery of a cylindrical part of a bobbin closely adheres to a side surface of the regular-square wire about to be wound. Thus, it is possible to form a coil having an excellent characteristic by winding the regular-square wire on the without making a gap.
1. A wire-winding apparatus for continuously winding a rectangular cross section wire member or a circular cross section wire member on a bobbin or a bobbin-less winding jig, the apparatus comprising:
a rotational drive part for holding and rotating the bobbin or the bobbin-less winding jig; and
an axial-direction drive part for moving a first driven member in an axial direction of the bobbin or the bobbin-less winding jib in synchronism with the rotation of the drive part, and three-dimensionally moving a second driven member independently upon the first driven member,
wherein the first driven member and the second driven member are brought into contact with the rectangular cross section wire member or the circular cross section wire member.
2. The wire-winding apparatus according to claim 1 , wherein the second driven member is a guide member for guiding the rectangular cross section wire member or the circular cross section wire member to wind on an outer periphery of the wound portion of the bobbin or the bobbin-less winding jig.
3. The wire-winding apparatus according to claim 2 , further comprising a holding mechanism for holding and cutting the rectangular cross section wire member or the circular cross section wire member, and the guide member moves integrally with the holding mechanism.
4. A wire-winding apparatus comprising:
first holding means for holding a wire source side of a rectangular cross section wire member;
second holding means three-dimensionally moving independently upon the first holding means, for holding an end side of the rectangular cross section wire member;
a rotational drive part for holding and rotating the bobbin or the bobbin-less winding jig; and
drive means for moving the first holding means and the second holding means, and the bobbin or the bobbin-less winding jig relatively with each other while maintaining the direction of the rectangular cross section wire member of the wire source side held by the first holding means and the direction of the rectangular cross section wire member of the end side held by the second holding means.
5. The wire-winding apparatus according to claim 4 , wherein the second holding means performs a binding operation of the rectangular cross section wire member after the first holding means and the second holding means, and the bobbin or the bobbin-less winding jig are relatively moved and at least one side surface of the rectangular cross section wire member is contacted with the bobbin or the bobbin-less winding jig.
6. The wire-winding apparatus according to claim 4 , wherein the second holding means is a cut-and-hold mechanism.
7. The wire-winding apparatus according to claim 4 , wherein the first holding means includes a pulley.
