Abstract:
1. A motor-plate unit for rotary labelling machines comprising: a motor for a plate of a labelling machine, said motor including: a housing provided with one or more connecting portions for connecting the motor to a carrousel of the labelling machine; a motor shaft being pivotally supported within the housing; a coupling flange having a first end connected to said motor shaft and a second end that can be connected to said plate, wherein the motor shaft is hollow, defining a through opening to allow alignment means or other accessories to have access to the plate through the motor, the motor-plate unit further comprising a plate suitable to support a container to be labelled, said plate being connected to the coupling flange of said motor, said plate having a central through opening aligned with the through opening of the hollow shaft, a first bearing supporting the shaft-flange unit within the housing in the vicinity of the coupling flange, and one or more second bearings supporting the shaft-flange unit within the housing in a position opposite the first bearing relative a rotor connected to the motor shaft, wherein the shaft-flange unit comprises a first abutment flange which is axially abutted against the first bearing and a second abutment flange which is axially abutted against the second bearing in the opposite direction to the first abutment flange, and wherein the housing comprises a first abutment shoulder which is axially abutted against the first bearing in the opposite direction to the first abutment flange and a second abutment shoulder which is axially abutted against the second bearing in a direction opposite the second abutment flange, such as to axially lock the shaft-flange unit relative to the housing.
