Abstract

Apparatus and method for applying tubular labels to empty or filled product containers at a labeling station including a reciprocally moveable labeling assembly and a container advancing mechanism including a pair of confronting, rotatable star wheels. The star wheels include arms for engaging and holding a container to be labeled at a label applying position. The star wheels operate to stabilize the container until the labeling applying assembly engages the container. The star wheels then move out of the labeling station to provide clearance for the label applying assembly. A cam drive system is utilized to both reciprocate the label applying assembly and the star wheel mechanism. Sensors monitor torque in the star wheels and terminate operation should excessive torque be encountered. An additional star wheel and associated guide are used to advance a container from either an inline or side conveyor to a container presenting position. Movement and/or position of the guide is monitored by a detent mechanism which releases the guide should a jam occur. Movement of the guide causes termination of apparatus operation.
