摘要:
A carton conveyor means for receiving cartons directly from a carton erecting and forming machine, and conveying the cartons along a linear path through a series of work stations for filling and sealing the cartons. The conveyor includes a pair of roller chains. Each of the roller chains has attached thereto a plurality of spaced apart metal lug carrier clips which are detachably mounted on the chain. A non-metallic conveyor lug is assembled to each of the lug carrier clips in a snap-in-fashion. The conveyor lugs function to transport the cartons along a pair of carton support rails. The conveyor lugs also function as guide means and bearing means for supporting the conveyor chains.

A preform locator and blow air valve apparatus, for use in a stretch pin assembly in a blow molding machine that produces hollow thermoplastic articles, which functions as a positive blow air shut-off valve means in the absence of a preform in a mold assembly. A tubular valve body is mounted in a stretch pin assembly, with a longitudinally movable blow air nozzle means slidably mounted in the valve body for carrying the preform and locating and sealing the preform against a shoulder in a mold assembly on a blow molding machine. A stretch pin is slidably mounted longitudinally through the blow air nozzle means for stretching a preform mounted on the nozzle means. A blow air passage means is operatively formed through the tubular valve body and blow air nozzle means for admitting blow air under pressure into a preform located in the mold assembly, by said blow air nozzle means, for blowing the preform into a finished article. The blow air nozzle means is moved by mechanical means into an initial position for loading a preform thereon. The blow air nozzle means is movable toward the mold assembly by either a mechanical means or a pneumatic means. The blow air nozzle means is moved a first distance toward the mold to locate and seal a preform in a mold assembly, and in the absence of a preform on the blow air nozzle means, the blow air nozzle means is moved a second distance, whereby it functions as a valve to close the blow air passage means to prevent loss of high pressure blow air and the resultant high noise levels.
摘要:
A bottom end closure for a liquid-carrying paperboard container, wherein particular diagonal and sloped score lines are formed on the inner closure panels by modified sealing jaws, such that, upon being engaged by the sealing jaws, the score lines enhance the formation of a concave shape to the bottom end closure. The result is that the filled container will sit flat and stand erect, without any interfering downward bulging.
摘要:
An article transfer station for transferring articles from a first conveyor to a second conveyor whereby the station can be selected to be either a station at which articles are carried through a predetermined angle about a substantially vertical axis while changing their orientations by the angle or a station at which articles are carried through the angle about the vertical axis without changing their orientations.

A carton squaring mechanism in a carrier for effectuating and maintaining a four-sided side-seamed open-topped carton in a squared configuration. The carrier includes a plurality of compartments, wherein adjacent compartments are separated by a pair of spaced-apart, laterally oriented, parallel fixed guides, a first off-center guide secured to one side of the carrier so as to be positioned closely adjacent to one of one pair of parallel guides and perpendicular to the planes of the latter. Each of the fixed guides has downwardly converging lower edges formed thereon for piloting the carton into the compartment. Each carton is first squared by engagement with oppositely disposed side rails, and then maintained square by the above referenced guides.
摘要:
A machine including a single power source for asynchronously operating dual indexing conveyors. The single power source is a reversible servo unit operatively connected to gear sets and one-way clutches to drive the conveyors. Alternately, the power source is a uni-directional rotating driver with linkage means to reciprocally move a rack operatively connected to gear sets with one-way clutches or ratchets and pawls.

A carton score line breaker assembly for breaking four end closure panels. The assembly includes two oppositely disposed pairs of breaker elements for, in turn, breaking the two oppositely disposed panels inwardly. Both pairs of elements are continuously rotating.

A four-armed pour spout fitment applicator adaptable to rotating two of the arms into open-topped cartons and applying flanged pour spout fitments outwardly through openings in a pair of adjacent carton top panels, while the other two arms are adapted to substantially receive two additional fitments transferred thereto by two air cylinders. External ultrasonic sealers have horns serving to engage the outer panel surfaces to seal the flanges of the fitments to the inner surfaces of the top panels around the openings.

摘要:
An adjustable container return device for use with a lift arm of a variable stroke lifter system for lifting variable height containers. The return device includes a vertically oriented rod threadedly movable at its bottom end relative to the lift arm; a laterally extending member operatively connected to the top end of the rod for vertical movement therewith; a retention mechanism operatively connected to said rod for retaining the laterally extending member in a selected radial direction so as to extend across an upper edge of an adjacent container; and an actuator mechanism for rotating the rod while permitting the rod to slidably move longitudinally, and thereby threadedly raising and lowering the rod relative to the lift arm, such that the laterally extending member accommodates different height containers.
