Alignment method and alignment device

Abstract

Provided are an alignment method and an alignment device by which, immediately before aligning, the leg parts of adjacent conductors do not interfere with each other. The alignment method, in which by providing a plurality of coil elements ( 40 ) in an annular shape and moving the plurality of coil elements ( 40 ) in a direction in which the diameter of the annular shape is reduced, the plurality of coil elements ( 40 ) are aligned in a state where turn sections ( 42 ) provided at substantially apex portions are alternately overlapped, wherein the plurality of coil elements ( 40 ) are aligned by moving each of the plurality of coil elements ( 40 ) toward an annularly shaped center, and while doing so, rotating the plurality of coil elements about a rotation axis ( 231 e ) that is parallel to the central axis (C 1 ) of the annular shape.

1 . An alignment method for aligning a plurality of substantially U-shaped electrical conductors in a state in which turn sections provided to a substantially apex portion thereof are alternately overlapped, by arranging the plurality of electrical conductors in an annular shape, and causing the plurality of the electric conductors to move in a direction to reduce the diameter of the annular shape, the method comprising:
 aligning the plurality of the electrical conductors by causing each of the plurality of the electrical conductors to rotate about a shaft that is parallel to a central axis of the annular shape, while causing to move towards the center of the annular shape.   
     
     
         2 . The alignment method according to  claim 1 , wherein each of the plurality of the electrical conductors is arranged in a state rotated by a predetermined angle about the shaft that is parallel to the central axis of the annular shape, when aligning by reducing the diameter of the annular shape. 
     
     
         3 . An alignment device for aligning a plurality of substantially U-shaped electrical conductors in a state in which turn sections provided to substantially apex portions thereof are alternately overlapped, by arranging the plurality of electrical conductors in an annular shape, and causing the plurality of the electric conductors to move in a direction to reduce the diameter of the annular shape, the alignment device comprising:
 a plurality of gripping devices that respectively grip a plurality of the electrical conductors; and   a movement device that causes the plurality of the gripping devices to move towards the center of an annular shape,   wherein each of the plurality of the gripping devices causes the electrical conductor to rotate about a shaft that is parallel to a central axis of annular shape, while moving by way of the movement device.   
     
     
         4 . The alignment device according to  claim 3 , wherein each of the plurality of the gripping devices has a biasing member that biases in the opposite direction to a direction rotating the electrical conductor by a predetermined angle about a shaft that is parallel to the central axis of the annular shape. 
     
     
         5 . The alignment device according to  claim 3 ,
 wherein each of the plurality of the gripping devices has an upper branch that grips the electrical conductor and is capable of rotating about the shaft that is parallel to the central axis of the annular shape, and a pin that is provided to the upper branch and projects on a movement path of the gripping device,   wherein a correction groove that guides the pin is provided on the movement path of the gripping device, and   wherein the upper branch gripping the electrical conductor is made to rotate by the pin being guided in the correction groove.   
     
     
         6 . The alignment device according to  claim 4 ,
 wherein each of the plurality of the gripping devices has an upper branch that grips the electrical conductor and is capable of rotating about the shaft that is parallel to the central axis of the annular shape, and a pin that is provided to the upper branch and projects on a movement path of the gripping device,   wherein a correction groove that guides the pin is provided on the movement path of the gripping device, and   wherein the upper branch gripping the electrical conductor is made to rotate by the pin being guided in the correction groove.
