NEEDLE ADVANCING/RETRACTING MEANS AND WINDING MACHINE

摘要

[Problem] To provide a needle advancing/retracting means and a series winding-type winding machine comprising said needle advancing/retracting means, wherein the alignment accuracy of a wound coil wire can be maintained at a high level even when a needle is made to circle around magnetic pole teeth at a high speed. [Solution] This needle advancing/retracting means that constitutes a series winding-type winding machine is positioned such that a servo motor for needle advancing/retracting motion is not affected by a mechanism for circling motion. The needle advancing/retracting means is structured such that rotational motion of the servo motor is transmitted by a shaft body and converted to a motion that oscillates an outer cylinder, an intermediate cylinder is positioned between the outer cylinder and an inner cylinder, and a phase difference is produced between the inner cylinder and the outer cylinder due to the oscillating motion that was transmitted only to the outer cylinder.
