  • Patent number: 10556767
    Abstract: A first leading end plate and a first rear end plate are provided at an upper part of a rotary table. When a conductor piece contacts the first leading end plate, a first contact detection sensor detects a contact of the conductor piece, and transmits a contact detection signal to a storage control unit. Upon receiving the contact detection signal, the storage control unit drives an air supply device for a predetermined period to spray air toward the conductor piece from a first air nozzle. The air spray brings the conductor piece into a tilted state with the rear end thereof moved downward. Even when the conductor piece contacts the first leading end plate and rebounds, the rear end thereof contacts an inner wall surface of the first rear end plate, thereby preventing the rear end of the conductor piece from getting over the first rear end plate.

  • Publication number: 20180036920
    Abstract: An insulating sheet is pushed into a first mold portion, and formed in a first shape along a shape of the first mold portion. The insulating sheet of the first shape inside the first mold portion is pushed into the second mold, and is deformed by a front mold portion, a front guide portion, and a bent convex portion of the front mold, and a rear mold portion and a rear guide portion of the rear mold, and is formed in a second shape. The insulating sheet of the second shape is inclined such that the front end portion overlaps the rear end portion in a first direction, and the width in a front-rear direction becomes narrower toward the front and the rear end portions. The insulating sheet inserted in the second mold and formed in the second shape is inserted into a slot of a stator core.

  • Patent number: 6870953
    Abstract: A method sorts out defect-free elements blanked out of a metal sheet for a belt for use in a continuously variable transmission. Each of the elements has a body and a head joined to the body with a pair of recesses defined therebetween. The elements are stacked in a transverse direction thereof into an annular form and bundled together by an assembly of stacked endless metal rings inserted in the recesses into a belt for use in a continuously variable transmission. The elements are inserted into a passage having a predetermined width to sort out and deliver those elements which have passed through the passage to a feed path. Respective images of the elements which have been delivered to the feed path are analyzed while in the feed path to compare the images with a reference element image. Elements which have entrapped foreign matter, outer profile deformations, and defects are rejected from the feed path, and other elements are fed through the feed path.

  • Patent number: 6502441
    Abstract: A blanked plate-like metal member for use as an element of a belt in a continuously variable transmission has an recess including an undercut therein. A stream of a liquid mixed with particle members is ejected toward an edge to be beveled of the recess thereby to bevel the recess. After the edge is beveled by deburring the edge, the recess is finished by removing a bulge formed on an outer surface of the edge by deburring the edge.

  • Patent number: 6290170
    Abstract: A strip guiding device for guiding a strip longitudinally along a feed path has a limiting mechanism for limiting the strip transversely at opposite side edges thereof to cause the strip to pass through a predetermined position in the feed path. The limiting mechanism has a pair of abutment members having respective abutment surfaces for abutting against the side edges of the strip along the feed path. The abutment members are movable in first directions toward and away from the side edges of the strip, and normally urged by a spring assembly to move away from the strip. The limiting mechanism also has a pair of pressing members having respective slanted surfaces held in sliding contact with respective sliding surfaces of the abutment members remote from the abutment surfaces. The pressing members are movable in second directions transverse to the first directions.
