IPC: H02K15/04
Filed: 1979-04-20
Abstract: PURPOSE: To automatically align and wind a piece of wire around a smoothing armature core by  moving wire guides in synchronization with the progress of the winding operation.   
     CONSTITUTION: A piece of wire 5 is drawn from a bush 21 through a main shaft 11, and the tip  of the wire is fixed at a specified position. Wire guides 34 are opposed so as to hold an armature  core 8, and the shaft 11 is rotated. When the winding operation begins, the shaft 11 is advanced  by the length of the diameter of the wire 5 for every one rotation of the flyer in synchronization  with the rotation of the shaft 11. A slider 24 is advanced by a specified amount with respect to the shaft 11. The movement of the slider 24 is transmitted through a mechanism; and a pair of wire  guides move in the direction of the shaft of an iron core 8, then, separated, and move along the  outer surface of the iron core 8. Thus, the wire 5 is aligned with and wound around the iron core.  After winding of one layer has completed, only the slider 24 is advanced, and the distance to the  iron core is widened by the length of the diameter of the wire 5. Then, the main shaft 11 and the  slider 24 are moved backward and the wire is wound to form the second layer. At this time, the  wire guides 34 perform the reverse movement, and the wire is aligned with and wound around  the outer surface of the iron core 8. In this way, the winding operation is automatically performed.
