Patent ID: 8561464

Claim:
A method for correcting an unbalance on a vehicle wheel including a rim and a tire, by adhesive-bonding at least one corrective element to an attachment surface on an inside of the rim, comprising the following steps: measuring the unbalance of the vehicle wheel in an unbalance measuring station, and producing correction data indicative of an amount of weights and attachment locations of corrective elements relative to two correction planes, and diameters of attachment surfaces in the cavity of the rim; rotating the vehicle wheel in the unbalance measuring station into a defined angular position and transmitting the defined angular position and the correction data to a control device for controlling an applicator head of a balancing station, the applicator head including two mounts for receiving the corrective elements; transferring the vehicle wheel from the unbalance measuring station to a balancing station by means of a gripper arranged on a handling device, said gripper gripping the tire of the vehicle wheel on its outside and centrally locating and holding the vehicle wheel in the balancing station; loading a corrective element which has one side coated with an adhesive and exhibits the weight amount determined in the unbalance measuring station into each one of the mounts of the applicator head of the balancing station; axially moving the vehicle wheel and/or the applicator head and rotating the applicator head, each in dependence upon the control device, in such a way that a first corrective element in the cavity of the wheel rim reaches the first correction plane and the first attachment location on the attachment surface, and fastening the first corrective element by pressing its adhesive-coated side against an attachment surface of the rim; axially moving the vehicle wheel and/or the applicator head and rotating the applicator head, each in dependence upon the control device, in such a way that the second corrective element reaches the attachment location in the second correction plane where it is attached by being pressed against the vehicle wheel, and transferring the balanced vehicle wheel from the balancing station to an outgoing conveyor unit for further transportation and handing-over the balanced vehicle wheel to the outgoing conveyor unit by the gripper on the handling device.
