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).

An in-mold label dispenser for a blow molding machine including at least one mold having mold sections movable between open and closed positions, and the mold sections including cavity sections which cooperatively define a cavity in which the blow molding is performed with the mold sections in the closed position and which permit ejection of a molded part in the open position, the label dispenser comprising: a label magazine for storing labels; a base; a dispensing head mounted on the base for movement along a first path from adjacent the label magazine to between the mold sections of the mold in the open position; a label carrier mounted on the dispensing head for movement along a second path transverse to the first path between retracted and extended positions; and a dispensing head and label carrier drive mechanism, said drive mechanism having an input that is mounted on the base and driven in association with the movement of the mold of the blow molding machine, said drive mechanism including a first solid mechanical drive that extends from the base to the dispensing head, said first solid mechanical drive having an input driven by the input of the drive mechanism to move the dispensing head in association with the movement of the mold, said drive mechanism also including a second solid mechanical drive that extends from the base to the label carrier, said second solid mechanical drive having an input driven by the input of the drive mechanism to move the label carrier in association with the movement of the mold, and said drive mechanism through the input thereof driving the inputs of the first and second solid mechanical drives actuating movement of the dispensing head and label carrier in association with the movement of the mold during a cyclical operation that: (a) initially moves the label carrier from the retracted position to the extended position with the dispensing head adjacent the label magazine such that the label carrier receives a label from the magazine, (b) thereafter moves the label carrier to the retracted position with the label thereon and also moves the dispensing head to between the mold sections of the mold in the open position, (c) subsequently moves the label carrier to the extended position to deposit the label on one of the mold sections within the cavity section thereof, and (d) finally moves the label carrier back to the retracted position and moves the dispensing head from between the mold sections back to adjacent the label magazine in preparation for the next cycle.
