Abstract

In a device for transferring a pallet-mounted electric motor armature to an armature winding formation station, the armature is made rigid with the pallet by members which enable it to be released therefrom, and the frame carrying the winding arms comprises a vertical gripper for gripping the armature and connected to drive means which cause it to rotate about its axis between said winding arms; means are also provided for vertically transferring either the armature alone or the armature rigid with the pallet from the conveyor belt to the winding arm zone in which the armature becomes released from the pallet and secured to the vertical gripper.

Claims

1. A device for transferring a pallet-mounted electric motor armature to an armature winding formation station, comprising a pallet, gripping means mounted on said pallet to releasably grip said armature to said pallet, a frame, spaced rotatable winding arms carried on said frame, rotatable drive means mounted on said frame, a vertical gripper for gripping the armature mounted on said drive means which cause said armature to rotate about an axis between said winding arms and means for vertically moving the armature whereby the armature releases from the pallet and is gripped by said vertical gripper, said gripping means mounted on said pallet to releasably grip said armature defining elastic blocks, a spigot, elastic means and a pin slidably mounted within said spigot and a pulling means, said blocks being interposed between said armature and said spigot and expandible in order to release the armature by the action of said pin sliding in said spigot against said elastic means, said pulling means biasing the pin against said elastic means to release the armature.

2. The device as claimed in claim 1, wherein said vertical gripper is movable vertically in order to grip the upper end of the armature and transfer said armature to between the winding arms, said arms being operated after releasing the armature from the pallet.

3. The device as claimed in claim 1, wherein said vertically moving means contact and raise said pallet in order to transfer the armature between the winding arms, where the vertical gripper grips an upper end of said armature and said armature is released from the pallet.

4. A device for transferring a pallet-mounted electric motor armature to an armature winding formation station, comprising a pallet, gripping means mounted on said pallet for gripping and releasing said armature, thereby holding said armature to said pallet, a frame, spaced rotatable winding arms carried on said frame, rotatable drive means mounted on said frame for rotating said armature about an axis between said winding arms, a vertical gripper mounted on said drive axis for gripping the armature and supporting same between said spaced rotatable winding arms and means for vertically moving the armature including means for contacting and raising said pallet to transfer the armature between the winding whereby the armature is released from the pallet and an upper end of the armature is gripped by said vertical gripper.
