Abstract

An in-mold label dispenser (22) for a blow molding machine is disclosed as including a dispensing head (56) mounted for rectilinear movement along a first axis A between a label magazine (48) and an open mold (28) and having a label carrier (58) mounted on the dispensing head for rectilinear movement between retracted and extended positions along a second axis B transverse to the first axis A. Rectilinear movement of the dispensing head (56) along the first axis A and coordinated extending and retracting rectilinear movement of the label carrier (58) along axis B transfers a label (50) from the magazine (48) to the mold (28) in preparation for the blow molding operation. The label dispenser (22) has particular utility when provided with a pair of the label carriers (58) to simultaneously transfer a pair of labels (50) to the open mold (28) within the confined space limitations involved. A drive linkage (66) is driven by a first gear unit (72) to reciprocally move the dispensing head (56), while a second gear unit (106) rotatably drives elongated supports (92) which mount the dispensing head (56) for its rectilinear movement and drive cams (108) that move the label carriers (58). Both the first and second gear units (72,106) are driven by a common input (156) to coordinate the movement of the dispensing head (56) with the movement of the label carriers (58).
