<p>In-mold labeling devices for blow molding machines and in particular to label transferring devices which place labels simultaneously in separate sides of the molds. One difficulty with such label application is to keep the label transfer time at a minimum in order to reduce the amount of time that the molds remain open. The device comprises a carriage (40) mounted on a piston rod (32), and a hydraulic cylinder (30) so as to extend the carriage between separated mold sections (16) and retract to between a set of label supply magazines (60). The label magazines are positioned so that a set of opposed carrying cylinders (42a) can extend and pick up the labels on carrying heads (46a) and place the labels in the mold sections. Alternatively, the carrying cylinders are mounted on a pair of extendable, converging clamp arms (70) which clamp onto the molded objects, remove them from the molding area and transport them to other processing stations. In another arrangement, an articulating arm (40), including a vacuum section head (92),and a label supply (100) are mounted on a mold platen (10) so that both the arm and label supply are carried by the platen as it moves to different blow molding stations. The arm moves the head from the label supply to between the molds.</p> |
