In-mold Labeler.

摘要

This relates to a label applicator (14) for applying labels (L) to mold cavities (12) of rotating mold units. The label applicator (14) is fixed relative to moving mold units and includes an extensible fluid motor (60) which carries a pick-up head or suction head (70) for moving the suction head in a straight line direction and return. The extensible fluid motor (60) is carried by a shaft (36) for oscillation between a label pick-up position and a label deposit position. The extensible fluid motor (60) is carried by a bracket (52) which, in turn, is carried by a shaft (28) of a rotary drive which is constructed to oscillate between two fixed positions which are spaced apart a preselected angular distance. The rotary drive may be a rotary actuator (18) or an extensible fluid motor. There is incorporated with the rotary actuator (18) a decelerator (32) for rapidly, yet smoothly, decelerating rotation of the bracket (52) carrying the extensible fluid motor (60). Suitable sensor means (M,H) are provided for timing the actuation of the label applicator (14) in accordance with the position of a mold cavity into which a label (L) is to be placed. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.
