ABSTRACT:
An apparatus and method for applying tubular labels to a product container at a labeling station including a reciprocally movable labeling assembly. The assembly is adjustably secured to carriage that is mounted for reciprocating movement at the labeling station. A drive system including a drive cam defining an asymetrical profile is operatively coupled to the carriage by a lever arrangement including a cam follower driven by the drive cam. The profile of the drive cam is configured to have a steep rise and a gradual drop so that the average speed at which the labeling assembly is driven through a label applying strobe is substantially less than the speed at which the assembly is driven through a return stroke thus reducing the stress applied to the label as it is installed. A fluid pressure operated actuator pressurized to a first predetermined pressure exerts a biasing force on the lever to urge the cam follower into contact with the drive cam. A sensor monitors the contact between the follower and cam and de-energizes the drive system and arrests rotation of the drive cam in the event loss of contact between the follower and the cam is sensed. The fluid pressure operated actuator can also be pressurized to a second predetermined pressure in order to drive the carriage to a retracted position. An indexing cam is co-driven with the carriage drive cam and operates a bottle advancing mechanism in synchronization with the labeling assembly.
