Abstract: A universal packer unfolds folded open side container blanks into fully opened containers and side loads them with complements of articles. The blanks are metered by a supply station and are propelled downstream to an unfolding station. The container flaps are spread apart, and expander arms enter the interior of each blank, thereby starting to unfold it. Erector arms strike the partially opened blank at the trailing edge thereof and push the trailing edge downward relative to the blank leading edge, thereby continuing the unfolding process. Drop lug assemblies emerge from under the blank trailing panel and pivot from a horizontal to a vertical attitude while in contact with the blank trailing panel, thereby completely unfolding the blank. Simultaneously with blank unfolding, a pair of grouper mechanisms forms the complements from a mass of the articles. The complements are propelled downstream in unison and aligned with the open containers.

Abstract: A mechanism packaging tape cassettes in cardboard sleeves including a controlled cassette guideway which advances cassettes to a packaging station and a controlled loading track which advances sleeves to the packaging station for positioning on the cassettes. The guideway may either receive cassettes from an incoming belt or a hopper. A pusher mechanism advances the cassettes to the packaging station while a retractable stop insures proper location of the cassette. The cassette is slightly raised above the surface of the guideway to be properly positioned for receiving the enclosing sleeve. The loading track includes a hopper to receive collapsed sleeves. The sleeves are released one-at-a-time into the loading track where a sleeve pusher advances the sleeves one-at-a-time into a die defined by opposed channels. The channels are spaced such that the continued pushing of the sleeve therethrough causes it to assume its appropriate rectangular configuration.

Abstract: Plates mounted on support structure of a machine for packaging articles in sleeve-type carriers act as guides for the moving articles and as detectors of article jams which occur inside open sleeves prior to the closing of the end panel flaps of the sleeves. The plates are mounted for movement toward and away from the moving carrier sleeves and are biased inwardly toward the path of movement of the carrier sleeves. When a jam occurs the pressure of articles moving outwardly of the sleeve causes the plate to pivot away from contact with a sensor, thereby automatically shutting down the machine. The plate extends to the flap closing area so as to detect jams at any point between the loading station and the flap closing station.

Abstract: A machine for feeding a collapsed beverage can carrier sleeve to a flight bar conveyor and introducing the sleeve in fully open condition to the pocket of the conveyor. After leaving the feed rolls the collapsed carrier sleeve is moved through a fixed guide by lugs on a movable chain. The end flaps on the upwardly facing side panel are held in place on the guide while the end flaps on the downwardly facing side panel are moved downwardly by a fixed cam surface. The substantially opened sleeve is then either given a final kick by rotating arms or is propelled by the feed lugs to accelerate it into the pocket while at the same time fully straightening and opening the sleeve. The carton dimension corresponding to the length of the pocket is the same as the length of the pocket, resulting in more pockets per conveyor length and permitting operation at slower conveyor speeds.

Abstract: An apparatus and method by which a single operator, at a single station, can pack pre-counted slugs of flat folded cartons, or trays, in one or more layers, in corrugated cases for discharge to a case taper several times faster than with manual packing by several operators. The "flats" are advanced in a longitudinal path on a secondary apron of a stacker, erect on one edge, pre-counted and divided into slugs, so that the single operator can slide each slug longitudinally past a one-way back stop onto a transfer table. The slug may be turned on its longitudinal axis by the operator for inspection and then compressed longitudinally by a ram against the back stop. The operator has already been presented with a single, flat, tubular case, from a stack of such cases, with the leading flaps folded back, and has manually erected the case and inserted it in a case gripper preferably poised above the table, thereby closing the minor bottom closure flaps.

Abstract: A machine for feeding beverage cans to open-ended carrier sleeves of varying capacities. When loading relatively small carrier sleeves, inboard conveyors and associated metering screws feed groups of cans to a flight bar conveyor which moves the groups through the open ends of the carrier sleeves. When loading relatively large carrier sleeves, outboard conveyors and associated metering screws are also operated after first replacing the inboard screws with screws able to separate cans into larger groups, the same size as those formed by the outboard screws. This arrangement feeds larger groups of cans which are then fed to the larger carrier sleeves. In one embodiment each conveyor comprises a longer upstream conveyor and a shorter downstream conveyor spaced a short distance therefrom to allow the flight bars to travel through the space between the conveyors when moving from the end of their upward run to the beginning of their horizontal downstream run.

Abstract: Apparatus is provided for opening folded open side carton blanks. The apparatus includes a first conveyor system for stripping blanks from a supply thereof at a first speed and for propelling the blanks downstream to a second conveyor system operating at a second speed greater than the first speed to accelerate the blanks and propel them to an unfolding station. The carton lower layer flaps are bent angularly downward. A pair of paddles having inclined leading edges rotate in horizontal planes to penetrate the space between the carton upper and lower layers and to lift the upper layer above the lower layer. The paddles also have bottom surfaces for holding the blank lower layer downwardly. The paddle tips travel at a faster speed than the second conveyor, so the tips slide forwardly to contact and push the blank leading panel forwardly to further unfold the flank.

Abstract: A case packer for loading open side cases and trays with generally upright articles includes apparatus for controlling the location of the case flaps during the loading operation.
