<P>PROBLEM TO BE SOLVED: To provide an automatic winding machine for manufacturing an air-core coil having a laminated structure of a plurality of unit winding portions whose inner circumferential lengths are different. <P>SOLUTION: The automatic winding machine comprises a wound core member 5 rotatably driven by a rotatably driving mechanism and an opposed member 3 provided oppositely to the wound core member 5, and the opposed member 3 comprises an insertion hole 31 into which the wound core member 5 is inserted, a pair of L-shaped winding aid members 32a, 32b covering part of peripheral surface of the wound core member 5 inserted into the insertion hole 31. The winding aid members 32a, 32b are connected to air cylinders 75, 75 respectively, and are reciprocatable between a first position projected from the end surface of the opposed member 3 and a second position housed within the opposed member 3. When respective winding aid members 32a, 32b are at the first position, a wire is wound about the peripheral surface of the winding aid members 32a, 32b, on the other hand when they are at the second position, the wire is wound about the peripheral surface of the wound core member 5. Thus, the air-coil having the laminated structure of the plurality of unit winding portions whose inner circumferential lengths are different is manufactured. <P>COPYRIGHT: (C)2007,JPO&INPIT |
