Patent ID: 8522423

Claim:
A device for feeding and attaching corrective elements for unbalance correction to rotors having a rotor axis, comprising at least one attachment device adapted to be positioned longitudinally to the rotor axis and including a receptacle for receiving a corrective element attachable to the outer circumference of the rotor, a stationary supply unit supplying corrective elements measured for the individual unbalance correction, and a feeding device adapted to feed supplied corrective elements to the attachment device, said feeding device including a transfer shuttle having a receptacle for receiving a corrective element and being capable of performing reciprocating movements between the supply unit and the attachment device on a guideway parallel to the rotor axis by means of a controllable motion drive mechanism, the transfer shuttle including a loading device configured for performing an active loading operation by extracting the corrective element from the receptacle of the transfer shuttle and inserting it into the receptacle of the attachment device, wherein the loading device is driven to perform an active loading operation by means of the controllable motion drive mechanism of the transfer shuttle.
