摘要:
An automatic rotary transfer apparatus and method for conveying a plurality of lightweight articles, such as empty bottles, at a high speed and, optionally, providing at least one additional function, such as de-flashing, trimming, or inspecting, in a single rotation of the rotary transfer apparatus. The apparatus includes a carriage ring having an outer perimeter defining a plurality of cavities spaced along the outer perimeter. Each cavity is adapted to receive a single article. A drive assembly indexes and rotates the carriage ring about a central axis of rotation and is synchronized to a continuous stream of the plurality of articles from an upstream operation, such as blow molding. The apparatus may further include a modification device, such as a de-flasher or trimmer, and an inspection station with a sensor for discharging damaged or imperfect articles, which performs the functions in a single rotation of the carriage ring.

A method for trimming a rectangular container and an apparatus trimming a rectangular container are provided, by which an appropriate cut surface with a possible crack or burr suppressed can be obtained when a rectangular container is trimmed. When a punch cutter 6 is initially allowed to cut into a rectangular tubular portion 10 of an untrimmed rectangular container 1a, the punch cutter 6 is inclined relative to a thickness direction of a cut area of the rectangular tubular portion 10, and then, the punch cutter 6 is circumferentially moved along a trim line TL on the rectangular tubular portion 10 to cut the rectangular tubular portion 10.

A flash removing punch pin is provided with a rotating mechanism wherein a flange is formed on an upper end portion on an outer circumference side portion of a cutting edge portion, and a plurality of grooves are formed in the axis center direction to the side of a casting part from the flange. An inner portion is slidably inserted into an inner cover, and the inner portion and a processing portion are moved by a spring cylinder in a direction to be separated from each other. The spring cylinder is compressed when the punch pin is in proximity to the casting part, and then the flange of the punch pin contacts a flange portion of the casting part. When the inner portion slides into the inner cover, the processing portion rotates along the axis with the inner portion.

A machine (10) for blow molding containers (100). The machine (10) has a stationary flow head (26) located proximate a turntable (12) on which molds (16) are mounted. A dwell cam mechanism (110, 120, 132) on the turntable causes the molds to accelerate ahead of the turntable, stop under the flow head to receive a parison (31), then accelerate to catch up with the turntable. This sequence allows the turntable to rotate continuously. Blow pins (30) mounted on the turntable inject gas into the molds to blow mold the parison while traveling a first path (144). Paddles (142) grip the molded containers and travel a second path (146) radially outward from the first path. The containers blow-molded from the parisons at a first station (18) are retained on the turntable after the turntable completes one full revolution and again passes the first station.
摘要:
A method of cutting or trimming a plastic body ejected from a blow mold that is especially suitable for high-output production lines. A log conveyor is continuously moved along a path. The body to be trimmed is placed between holders carried by the conveyor and trimmed by rotating the holders as the conveyor moves past a trim knife extending along the path.

An apparatus for cutting a plastic blow molded body ejected from a blow mold, the apparatus includes spaced holders rotatable about a common axis. Each holder receives an end of a plastic body. A first drive rotates the holders about the axis. A second drive moves the holders and plastic body against a trim knife to cut the body. The holders start and stop rotation with the body at a predetermined orientation with respect to the common axis.

An apparatus for trimming a plastic blow molded log having a neck offset to a side of the log and extending along an axis. The apparatus includes spaced holders that receive the ends of the log. A first drive rotates the holders about the neck axis and a second drive moves the holders and log against a trim knife to trim the neck.

A blade for trimming flash from a plastic container. The blade includes a blade body having a first side end, a second side end, a front end and a rear end, the blade body including a blade edge at the front end of the blade body between the first and second side ends, a depression on the blade body formed between the first and second side ends and encompassing the blade edge, a first sidewall formed between the depression and the first side end of the blade body, and a second sidewall formed between the depression and the second side end of the blade body.

A process for cutting hollow molded plastic parts uses two knife cuttings in sequence. A first knife blade (42) is pressed on an uncut hollow molded plastic part for cutting therethrough with a guillotine blade action to form an access hole (46, 48) in the plastic part (10). The plastic part (10) may be secured onto a clamp (34, 36) for the first guillotine blade action. An outer support clamp (50, 52) is then secured about the plastic part with an outer side of the support clamp being positioned in proximity to the finished cut edge (65) of a finished plastic part. A mandrel (54) is inserted into the access hole (46, 48) of the part. The inner end of the mandrel is axially spaced from the outer side of the support clamp to allow a thin knife blade therebetween. A thin knife blade (62, 64) then cuts off the rough edge (47) to provide a finished cut edge (65) in the plastic part axially interposed between the outer side of the support clamp and the inner mandrel.
摘要:
A head trimmer machine for cutting off excess material from a cylindrical portion of a blow molded bottle includes a fixture, a spindle rotatably mounted in the fixture, a cutting head attached to the spindle for rotation therewith, a cutter mounted to the cutting head, and a vacuum source for collecting the trimmed material by suction. The cutting head has a central passage so that it can fit down over the head of the blow molded bottle. The cutter is supported in the cutting head for movement between retracted and extended positions. In the extended position, the cutter extends into the central passage of the cutting head to cut the head or other excess material from the neck of the bottle as the cutting head turns. The spindle includes a central passage aligned with the central passage of the cutting head and the excess material is removed by being drawn through these passages by a gaseous flow created by the vacuum source. Movement of the cutter can be pneumatically controlled by a pair of air pistons located on the cutting head, with the air pistons receiving pneumatic control signals from an outside source via rotational pneumatic couplings between the fixture and spindle.
