Abstract

A removing apparatus ( 2 ) includes a first removing section ( 11 ) and a second removing section ( 12 ). The first removing section ( 11 ) includes a rotating disk ( 15 ) and a driven roller ( 16 ). The rotating disk ( 15 ) has a pair of left and right first to fourth left and right removing blades ( 21 ) to ( 24 ) attached thereto. When the rotating disk ( 15 ) rotates in a counterclockwise direction, a coil conductive wire ( 3 ) sandwiched between the rotating disk ( 15 ) and the driven roller ( 16 ) is transferred in a transfer direction. When the rotating disk ( 15 ) rotates in a counterclockwise direction, the left and right side surface portions of the insulating coating ( 4 ) are removed by a blade portion ( 21 b ) of a pair of left and right first left and right removing blades ( 21 ).

First claim

What is claimed is:

1. A removing apparatus which removes an insulating coating from a rectangular conductive wire of a conductor, the conductor having the rectangular conductive wire with a rectangular shape and the insulating coating covering the rectangular conductive wire, the removing apparatus comprising:
a transfer unit configured to transfer the conductor in a predetermined direction; and
a removing unit which has a removing blade which is displaceable so as to remove the insulating coating on a removal target side surface of the conductor from the rectangular conductive wire, the removing unit being configured to displace the removing blade while the transfer unit is transferring the conductor without stopping the transfer of the conductor by the transfer unit, to remove the insulating coating on the removal target side surface from the rectangular conductive wire with an interval of a predetermined pitch in the predetermined direction between removed sections of the insulating coating.

2. The removing apparatus according to claim 1 , wherein
the removing blade is displaceable in an inclination direction inclined with respect to a perpendicular direction perpendicular to the predetermined direction in a plane parallel to the removal target side surface, and
the removing unit displaces the removing blade in the inclination direction so as to abut against the insulating coating on the removal target side surface.

3. The removing apparatus according to claim 2 , wherein
the removing unit comprises a rotating disk, the rotating disk provided with the removing blade, the rotating disk being rotatable and being rotated to displace the removing blade in the inclination direction so as to abut against the insulating coating on the removal target side surface, and
by rotating the rotating disk to rotate the removing blade, the insulating coating on the removal target side surface is removed from the rectangular conductive wire by the removing blade.

4. The removing apparatus according to claim 3 , wherein
the rotating disk transfers the conductor in the predetermined direction with an outer peripheral surface of the rotating disk abutting against a surface other than the removal target side surface of the rectangular conductive wire.

5. The removing apparatus according to claim 2 , wherein
the transfer unit is disposed separately from the removing unit, and comprises a transfer member which transfers the conductor.

6. The removing apparatus according to claim 2 , wherein
the removing unit displaces the removing blade in the inclination direction in a direction along the predetermined direction so as to abut against the insulating coating on the removal target side surface.

7. The removing apparatus according to claim 6 , wherein
the removing blade comprises a blade portion which has a cutting edge for removing the insulating coating and overlaps the insulating coating in a plane parallel to the removal target side surface when displaced in the inclination direction, wherein
a leading end of the blade portion is recessed in a direction opposite to the predetermined direction from a direction orthogonal to the inclination direction on the leading end of the cutting edge when the leading end of the cutting edge is displaced in the inclination direction to abut against the insulating coating, and
a trailing end of the blade portion is recessed in the predetermined direction from the direction orthogonal to the inclination direction on the trailing end of the cutting edge when the leading end of the cutting edge is displaced in the inclination direction to abut against the insulating coating.

8. A removal method of removing an insulating coating from a rectangular conductive wire of a conductor with a rectangular shape, the conductor having the rectangular conductive wire with a rectangular shape and the insulating coating covering the rectangular conductive wire, the removal method comprising:
a transfer step of transferring the conductor in a predetermined direction; and
a removal step of removing the insulating coating on a removal target side surface from the rectangular conductive wire by displacing a removing blade which is displaceable so as to remove the insulating coating on the removal target side surface of the conductor from the rectangular conductive wire while the conductor is being transferred in the transfer step without stopping the transfer of the conductor to remove the insulating coating on the removal target side surface from the rectangular conductive wire with an interval of a predetermined pitch in the predetermined direction between removed sections of the insulating coating.
