  • Patent number: 6367360
    Abstract: Apparatus (10) for trimming a blow molding (12) includes a rotary trimming assembly (16) rotatively mounted and driven on a trimmer head (14). The trimming assembly (16) includes a tube (18) of a rotary member (46) aligned with the blow molding such that operation of an actuating mechanism (20) provides cam actuated movement of a knife holder (48) to perform the trimming which allows the trimmed off blow molding portion to move through the tube (18) away from the trimmed blow molding in preparation for the next trimming cycle. A vacuum source (36) draws a vacuum within a conduit (34) connected to the tube (18) to provide the movement of the trimmed off blow molding portion away from the trimmer head.

  • Patent number: 6186767
    Abstract: A dispensing head (36) for an in-mold labeling system includes a lever assembly (106) rotatively driven by a rotary drive member (74) and having a pair of levers (108) that are adjustable with respect to the rotary drive member independently of each other. Each lever (108) has a cam and follower connection (112) to an associated label carrier (38) such that rotation of the rotary drive member (74) provides movement of the label carriers (38) between retracted and label transfer positions.

  • Patent number: 6183238
    Abstract: 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 second cam mechanisms (48, 66) respectively driven by the servomotors to move a dispensing head (36) between supply and delivery locations and to move a label 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 second electrical servomotors (46,64) in coordination with the machine operation but independently of each other.

  • Patent number: 5167968
    Abstract: Apparatus (30) for finishing a blow molding (24) is disclosed as including a rotary head (42) on which a first knife holder (44) is provided for mounting a knife (46) for radial movement with respect to the rotational axis (A). A second knife holder is mounted in a diametrically opposite relationship to the first knife holder and actuated so as to maintain a balanced relationship during rotation of the rotary head. An actuating mechanism (48) actuates the knife holder (44) to move the knife (46) radially inward with respect to the rotational axis (A) during rotation of the head (42) to cut the blow molding received thereby and thereby provide finishing that removes excess material. The actuating mechanism (42) is preferably constructed as a cam actuator (50) including a cam follower (56) and a cam (58) that operate after a first portion (52) of the rotary head (42) is stopped from continued axial movement as a second portion (54) of the rotary head continues to be moved axially during the rotation.

  • Patent number: 5067890
    Abstract: An in-mold label supply system (20) for a plastic blow molding machine (22) has particular utility for use with rotary wheel type blow molding and includes a hopper assembly (68) including a feed hopper (70) for positioning discrete sheet-like labels (72) in a vertical feed stack (74). A feeder (76) of the system includes a feed member (78) that selectively grips the lowermost label (72) of the feed stack (74) to provide delivery thereof to a conveyor (80) for conveyance to the blow molding machine (22) where a label dispenser (82) transfers the label (72) to a mold (24) of the machine for placement within a mold cavity section (28). A gate (104) of the feeder (76) cooperates with the feed member (78) to permit only the lowermost label (72) to be fed from the feed stack (74) to the conveyor (80). The feed member (78) is preferably embodied by a feed roller (114) to which pressurized gas and a vacuum are alternately fed to control the label feeding.
