PLASTIC BLOW MOLDING IN-MOLD LABELING SYSTEM

摘要

An in-mold labeling system for use with a rotary blow molding machine (10) includes first and second electrical servomotors (46, 64) and first and seco nd cam mechanisms (48, 66) respectively driven by the servomotors to move a dispensing head (36) between supply and delivery locations and to move a lab el carrier (38) on the dispensing head between retracted and label transfer positions independently of each other. A sensor (92) of the system senses rotation of a rotary wheel (12) of the machine to operate first and second electrical controllers (84, 86) that respectively operate the first and seco nd electrical servomotors (46, 64) in coordination with the machine operation b ut independently of each other.
