Armature winding apparatus with improved armature loading and unloading mechanism
First Claim
1. Apparatus for successively winding armatures each having an armature core and a commutator mounted on an armature shaft, comprising a set of opposing chucks positioned at an armature winding station and having means for gripping the core of each armature, means including a rotatable flyer for winding wire coils on said armature core at said winding station, a turret having a plurality of angularly disposed armature shaft gripping members, means supporting said turret for rotary indexing on a generally horizontal axis in a step-by-step manner, each of said shaft gripping members having means for releasably gripping an end portion of each armature shaft with the armature projecting in a cantilever manner outwardly from said gripping member, means for moving said turret for successively transferring each said gripping member and the corresponding armature from an armature receiving station to a circumferentially spaced armature unloading station through said armature winding station, means for successively supplying unwound armatures and their corresponding shafts to said shaft gripping members at said receiving staton, and means for successively removing the armature shafts of wound armatures from sad gripping members at said unloading station.

Abstract
An armature winding machine supports a combined armature loading and unloading mechanism which includes a turret supported by a carriage for rotary indexing movement on a horizontal axis. The carriage is supported for horizontal linear movement by a set of guide rods projecting outwardly from the winding machine, and the carriage and turret are moved between inner and outer positions by actuation of a fluid cylinder. The turret includes a set of annularly arranged gripping members which successively grip the unwound armatures supplied from a vertically moveable magazine located above the turret. While each unwound armature is being transferred to the winding station by the turret, a wound armature is simultaneously transferred by the turret to an unloading station where it is released from its gripping member. The turret automatically indexes in response to linear movement of the carriage.

- 12. In armature winding apparatus including means for winding wire coils on an unwound armature including an armature core mounted on an armature shaft, an improved mechanism for successively loading unwound armatures into the armature winding means and for simultaneously unloading wound armatures from said winding means, said mechanism comprising a turret having a plurality of angularly arranged gripping members each adapted to grip the shaft of an armature, a carriage supporting said turret for rotaty indexing movement, means for indexing said turret in a step-by-step manner for successively transferring each gripping member from an armature receiving station to a circumferentially spaced armature unloading station through an armature winding station adjacent said winding means, means for successively supplying armatures to said gripping members at said armature receiving staton, means supporting said carriage for movement of said turret between an extended position adjacent said winding means to provide for inserting each armature axially into said winding means and a retracted position for indexing said turret with armatures being carried by said gripping members, and means for successively removing wound armatures from said gripping members at said aramture unloading station.
