ABSTRACT:
An automatic assembly system for assembly of transformer laminated cores of the type having three parallel legs and two yokes. The laminations are stacked in a simple or complex configuration on a movable support frame on tracks, which receives the core laminations at a lamination loading station from four movable platforms on independent tracks. The platforms are grouped circumferentially about the support frame at four lamination feed positions while it is at the lamination loading station and have thereon stacked corresponding core laminations that are to be stacked on the support frame in a proper sequence and position order for forming a transformer laminated core. The system has four travelling gantry cranes that are on independent tracks and are each provided with a pick-up frame having suction cups arranged thereon for lifting the laminations individually from corresponding platforms at the four lamination feed positions and depositing them on the support frame in a properly stacked relationship. The individual cranes have the pick-up frame thereof movable laterally horizontally on trolleys on the individual cranes so that the laminations can be deposited in the core complex figuration. The support frame is cyclically movable form the lamination loading station to a remote station for removal of a completed transformer core therefrom and is then returned to the lamination loading station for forming of a next transformer laminated core thereon. The movable platforms are cyclically moved from their lamination feed positions to individual lamination loading positions where they are loaded with corresponding lamination and returned to their corresponding lamination feed positions for successively forming the individual transformer laminated cores.
