Abstract

A film peeling method for a film-coated flat wire that is performed by a film peeling device including: a rotational holder that can rotationally convey in a perpendicular direction to a rotational axis; a positioning mechanism that positions a film-coated flat wire in a longitudinal direction; and a working section that is provided in plural, aligned at specified intervals, and works an end portion of the film-coated flat wire, the method includes: holding the film-coated flat wire that is cut in a specified length in advance by the rotational holder; rotationally conveying the film-coated flat wire that is held by the rotational holder in the perpendicular direction to the rotational axis; positioning the conveyed film-coated flat wire by the positioning mechanism; and working the end portion of the film-coated flat wire by the working section.

First claim

What is claimed is:

1. A film peeling method for a film-coated flat wire performed by a film peeling device including:
a rotational holder that can rotationally convey the film-coated flat wire in a perpendicular direction to a rotational axis of the film-coated flat wire;
a positioning mechanism that positions the film-coated flat wire in a longitudinal direction; and
a working section that is provided in plural and aligned at specified intervals to peel an end portion of the film-coated flat wire,
the method comprising:
cutting the film-coated flat wire to a specified length;
holding the film-coated flat wire that is cut in the specified length in advance by the rotational holder;
rotationally conveying the film-coated flat wire that is held in the holding step by the rotational holder in the perpendicular direction to the rotational axis of the film-coated flat wire, the film-coated flat wire is perpendicularly conveyed with respect to the longitudinal direction thereof;
positioning the conveyed film-coated flat wire by the positioning mechanism; and
peeling the end portion by the working section.

2. The film peeling method for a film-coated flat wire according to claim 1 , wherein the rotational holder includes plural rotational holders that are connected annularly to one another.

3. A film peeling method for a film-coated flat wire performed by
a film peeling device including:
a rotational holder that can rotationally convey the film-coated flat wire in a perpendicular direction to a rotational axis of the film-coated flat wire;
a positioning mechanism that positions the film-coated flat wire in a longitudinal direction; and
a working section that is provided in plural and aligned at specified intervals to peel an end portion of the film-coated flat wire,
the method comprising:
cutting the film-coated flat wire to a specified length;
holding the film-coated flat wire that is cut in the specified length in advance by the rotational holder;
rotationally conveying the film-coated flat wire that is held in the holding step by the rotational holder in the perpendicular direction to the rotational axis;
positioning the conveyed film-coated flat wire by the positioning mechanism; and
peeling the end portion by the working section,

wherein the positioning and the peeling are each performed at least three times, a first surface that includes one side of an outer periphery of a cut surface that is formed when the film-coated flat wire is cut perpendicularly to the longitudinal direction, first positioning includes positioning the first surface at a 45 degree incline relative to a conveyance surface on which the film-coated flat wire is conveyed by the rotational holder, first working includes peeling the end portion of the film-coated flat wire in the working section to form a second surface, second positioning includes positioning by which the first surface is inclined for 45 degrees to the conveyance surface by the rotational holder, second working includes peeling the end portion of the film-coated flat wire in the working section to form a third surface that is perpendicular to the second surface that is formed in the first working, third positioning includes positioning by which a lateral surface of the film-coated flat wire is in parallel with the conveyance surface by the rotational holder, and third working includes peeling the end portion of the film-coated flat wire in the working section to form a fourth surface that is angled at 45 degrees with respect to the second surface and the third surface,
wherein the first, second, and third workings are each performed at least three times.

4. The film peeling method of claim 3 , the film peeling device further including:
a rotational holder that can rotationally convey the wire in a direction that is perpendicular to a rotational axis of the film-coated flat wire;
a positioning mechanism that positions the film-coated flat wire in a longitudinal direction; and
a working section that is provided in plural and aligned at specified intervals to peel an end portion of the film-coated flat wire,
the method comprising:
cutting the film-coated flat wire to a specified length;
holding the film-coated flat wire that is cut in the specified length in advance by the rotational holder;
rotationally conveying the film-coated flat wire that is held in the holding step by the rotational holder in the direction that is perpendicular to the rotational axis;
positioning the conveyed film-coated flat wire by the positioning mechanism;
peeling the end portion by the working section,
holding the film-coated flat wire by the rotational holder such that the first surface faces the conveyance surface after the third working; and
crushing the end portion of the film-coated flat wire in one direction to crush a burr that is produced on the film-coated flat wire by peeling in the working section.
