AUTOMATIC WINDING START TERMINAL PROCESSING AND WINDING METHOD FOR WIRE ROD AND AUTOMATIC WIRE WINDING MACHINE WITH WINDING START TERMINAL PROCESSING MECHANISM

摘要

PURPOSE: To smoothly wind a wire rod while preventing a winding wore from damage by temporarily stopping a wire rod winding start end onto a winding drum, and cutting off a terminal part of the winding start end, so as to reduce a contact range of a winding start end part with the winding wire wound or a bobbin. ;CONSTITUTION: When a bobbin 2 is arranged in a winding position (b) by a bobbin transfer mechanism 4, a bobbin rotating mechanism 5 is driven, and by advancing a set flange 5c, the bobbin 2 is interposed between the set flange 5c and a rotary drive flange 5b, and set to a fixed position. A winding start end part 1a of a wire rod 1 is interposed between a side plate 2b of the bobbin 2 and the rotary drive flange 5b. Under this condition, the bobbin 2 is rotated in a plurality of times to temporarily wind the wire rod 1 onto a winding drum 2a of the bobbin 2, and the winding start end part 1a of the wire rod 1 is retained onto the winding drum 2a and temporarily stopped. Then by temporarily rotating the bobbin 2 stopped, a terminal part of the winding start end part 1a, protruded from a temporary winding 1b, is cut off by actuating a winding start terminal cutoff mechanism 6. Then the bobbin 2 is rotated again, and a full bobbin is formed.;COPYRIGHT: (C)1994,JPO
