Abstract

PURPOSE:To obtain a winding machine to perform automatically winding work by inserting a fine wire into a fine penetrating hole without depending on man's hands by a method wherein a wire feed part on one side out of a pair of wire feed parts provided with wire driving mechanisms is provided transference freely relatively to the other wire feed part and a winding body. CONSTITUTION:When a wire 20 reaches the taper type part of the second guide hole 8 of a first wire feed part A, movable bodies 4, 5 are separated to be released mutually according to the open-and-close mechanism of a second wire feed part B. Thereupon the second wire feed part B is returned to the original position directly under the first wire feed part A according to a transfer part, and the movable bodies 4, 5 are closed. Namely, the guide hole 8, the penetrating hole of the first wire feed part A and the first guide hole 7 of the second wire feed part B are arranged coaxially approaching mutually. When the guide rollers 12a, 12b of the first and the second wire feed parts A, B are rotated, the wire 20 is inserted in the penetrating hole through the guide hole 8 of the first wire feed part A, and reaches the guide hole 7 of the second wire feed part B. As a result, a loop 29 is formed, and the loop thereof is wound around a winding body C. Winding work is performed by repeating the same process hereafter.

The rotation may be transmitted, for example, by a gear mechanism without using the ring flI. Furthermore, the guide rollers are not limited to one pair, and may be provided in series or in multiple stages depending on the case. Furthermore, the other of the pair of guide rows 2 may be formed of a flat plate. Furthermore, in order to form the guide holes (71, (81), grooves (7a), (7b), (8a), (8b) of the same size are formed in each of the movable bodies (4), (51). Alternatively, a groove may be carved only on one side to form a guide hole.

Furthermore, in the above embodiment, the moving section presses the second wire feeding section (B) to move relative to the wound body (C) and the first wire feeding section (A). There are, but
On the contrary, the second wire feeding part (B) is fixed and the wire to be wound (
