Label dispensing head for plastic blow molding in-mold labeling system

A dispensing head for an in-mold labeling system for use with a plastic blow molding machine to transfer labels from a pair of label magazines adjacent the blow molding machine to open molds thereof prior to mold closing for blow molding, the dispensing head comprising:

• a head member that is mounted for movement between a supply location adjacent the label magazines and a delivery location between mold members of an open mold;
• a pair of label carriers mounted on the head member for movement between a retracted position and a label transfer position;
• a rotary drive member that is rotatable in response to the blow molding machine operation;
• a lever assembly rotatively driven by the rotary drive member and having a pair of levers that extend from the rotary drive member in generally opposite directions and are adjustable with respect to the rotary drive member independently of each other, and each lever having a cam and follower connection to an associated label carrier such that rotation of the rotary drive member provides movement of the label carriers between the retracted and label transfer positions such that the label carriers are moved from the retracted position to the label transfer position while the dispensing head is in the supply location to receive labels from the label magazines and are then moved back to the retracted position for movement of the dispensing head to the delivery location where the label carriers are again moved to the label transfer position to transfer the labels to an adjacent open mold prior to mold closing for the blow molding.

• a pair of label carriers;
• a pair of spaced and parallel rails that mount the pair of label carriers on the head member for movement between a retracted position and a label transfer position;
• a rotary drive member that is located between the pair of parallel rails and is rotatable in response to the blow molding machine operation;
