Abstract

A transfer mechanism for transferring armature forms between a supply pallet and an armature winding machine comprises a turret plate rotatable through 180° angles for presenting opposite margins thereof successively to said supply pallet and said winding machine. In operation, the supply pallet is indexed to receive wound armature forms held by a first armature gripping mechanism mounted on said turret plate and to supply unwound armature forms to said first gripping mechanism. As these events occur, the turret plate supports a second armature gripping mechanism which presents unwound armature forms to the winding machine. The winding machine has winding guide members cooperating with semicircular spaces located in a post projecting upwardly from a mounting plate supporting the turret plate to support the unwound armature forms in position for the winding of coils thereon. The armature gripping mechanisms include means to rotate the armature forms and also includes means to appropriately position the wire being wound for tang connections. After such coil winding, the turret plate is rotated 180° so that the wound armatures gripped by the second gripping mechanism can be returned to the supply pallet and unwound armatures can be simultaneously transferred by the first gripping mechanism for presentation to the winding machine.

Claims

1. Apparatus for transferring armature forms between a mechanism for supplying said forms and a machine for winding said forms which comprises:

a turret plate disposed between said supply mechanism and said winding machine,

first armature gripping means, said turret plate having first means supporting said first armature gripping means for movement along said turret plate,

second armature gripping means, said turret plate having second means supporting said second armature gripping means for movement along said turret plate,

means for moving said first armature gripping means along said turret plate toward one margin of said turret plate and oppositely toward the center of said turret plate,

means for moving said second armature gripping means along said turret plate toward another margin of said turret plate and oppositely toward the center of said turret plate,

each said armature gripping means comprising a collet mechanism and means for operating said collet mechanism,

and means for rotating said turret plate from a first position, wherein said first armature gripping means when moved toward said one margin is located adjacent said supply mechanism and said second armature gripping means when moved toward said other margin is located adjacent said winding machine, to a second position reversing the positions of said first and second armature gripping means and for reversely rotating said turret plate to return said first and second gripping means to the first-mentioned position so that said armature gripping means can be used to grip an unwound armature form from said supply mechanism, position said unwound armature form adjacent said winding machine and return to said supply mechanism by repeated operation of said turret plate rotating means.

2. The apparatus of claim 1 wherein said supply mechanism includes means for receiving a wound armature form after being wound at said winding machine.

3. The apparatus of claim 2 wherein said supply mechanism includes a pallet having spaced bores for holding said unwound and wound armature forms.

4. The apparatus of claim 1 wherein said armature gripping means further comprise means for indexing the armatures gripped thereby, said indexing means comprising means for rotating said collet mechanisms, there being one collet mechanism rotating means for each said armature gripping means.

5. Apparatus for transferring armature forms between a mechanism for supplying and receiving said forms and a machine for winding such forms which comprises:

a turret plate extending between said mechanism and said winding machine, said turret plate having opposite margins,

first armature gripping means supported on said turret plate for movement toward one of said margins,

second armature gripping means supported on said turret plate for movement toward the other of said margins,

means for rotating said turret plate 180°

from a first position wherein said one margin is disposed proximal said mechanism and said other margin is disposed proximal said winding machine to a second position wherein the positions of said margins are reversed,

and first and second actuator means for moving said first and second gripping means, respectively, inwardly away from said margins for the rotation of said turret plate and outwardly toward said margins following rotation of said turret plate

so that, following rotation of said turret plate to said first position, said first actuator means moves said first armature gripping means toward said one margin for gripping an armature form and said second actuator moves said second armature gripping means toward said other margin to support an armature form for winding by said winding machine, and,

following rotation of said turret plate to said second position, said first actuator means moves said first gripping means toward said one margin to present the armature form gripped thereby for winding by said winding machine and said second actuator means moves said second gripping means toward said other margin to return to said mechanism the wound armature form supported thereby.

6. In an armature winding assembly:

an armature winding machine,

means to supply armature forms for winding,

a turret plate mounted for rotation about an axis disposed between said winding machine and said supply means,

first armature gripping means disposed on said turret plate to one side of said axis,

second armature gripping means disposed on said turret plate to an opposite side of said axis,

said turret plate having slide means supporting said first and second armature gripping means,

means for advancing said first armature gripping means along said slide means toward a margin of said turret plate and means for advancing said second armature gripping means along said slide toward another margin of said turret plate,

each said armature gripping means comprising a collet mechanism and means for operating said collet mechanism,

and means for rotating said turret plate about said axis

from a first position wherein said first armature gripping means when moved toward said one margin is located adjacent said supply means and said second armature gripping means when moved toward said other margin is located adjacent said winding machine

to a second position reversing the positions of said first and second armature gripping means

and for reversely rotating said turret plate to return said first and second armature gripping means to the first position

so that, by repeated operations of said rotating means, said armature gripping means can each be used successively to grip an unwound armature from said supply means, support said unwound armature for winding adjacent said winding machine, and then return the wound armature to said supply means.

7. The armature winding assembly of claim 6 including upwardly projecting post means adjacent said winding machine, said post means having plural semicircular spaces therein, said winding machine having plural winding guides, one for each said semicircular space, for cooperating with said semicircular spaces to support armature forms for the winding of wire thereon by said winding machine, said semicircular spaces and said winding guides alternately supporting armature forms received from said first and second armature gripping means.
