  • Patent number: 4873813
    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.

  • Patent number: 4835940
    Abstract: An apparatus for closing bottles by means of closure caps, such as, crown caps or the like, including a closing machine, a closing member rotating together with a bell-type centering or guard member along the periphery of the closing machine. A spring-biased pressure die is mounted in the closing member so as to be movable in axial direction. A cap transfer station is arranged at one point of the cycle of rotation of the closing machine. The position of the centering member with a cap support member is adjustable relative to the pressure die during the movement. The centering member and cap support member, when in the cap transfer position, are fixedly supported on the closing member by means of the pressure die and/or by means of control members of the centering member.

  • Patent number: 4821490
    Abstract: This invention relates to closing an open end of a pailette containing a biological element. The invention includes heating a dose of thermo-plastic material to a flowable condition and injecting the dose into the cold open end of the paillettes so that the material adheres to the inner wall of the paillette and solidifies to form a stable plug closing the end. The thermo-plastic material is preferably in the form of solid sticks. A valve in closing apparatus opens and closes communication with a reservoir containing the thermo-plastic material under pressure and defines a pre-determined volume for the dose. The invention is especially applicable to the production of paillettes for use in artificial insemination.

  • Patent number: 4807423
    Abstract: The present invention relates to a device for feeding covers to a continuously operating container closing machine. The device makes it possible continuously to feed covers to closure tools which revolve in a circular path and during their rotary movement descend, for the closing, onto containers moved past below the closing station, so that the closure tools place and close the covers on the containers. For the transfer of the covers, a cover guide path is moved over a certain region of the rotary movement of the closure tool synchronously and in alignment with the closure tools so that the covers can be delivered during this phase to the closure tool.

  • Patent number: 4793118
    Abstract: The invention generally relates to a method for ordering a coherent packaging line for storing in storage units or for intermediate buffering during a packaging process, wherein prior to the cutting into product portions, the packaging line discharged at the full process speed is wound onto winding plates and the winding formed is intermediately stored, so that then further process stages can be performed thereon, e.g. a singling or cutting at a random time and at a random process speed. The apparatus performing the method has a winding plate drive and winding plates drivable by it for winding a coherent packaging line, together with a supply mechanism for supplying empty winding plates to the winding plate drive and a conveying means for supplying a packaging line to the winding plates. Several supply means can be associated with one winding plate drive.

  • Patent number: 4790124
    Abstract: An article packaging apparatus with a cylindrical cassette having a tube made of resin fitted on the outer peripheral surface thereof is mounted below a charging station for charging articles. Heated press heads for heating and fusing the resin tube are arranged below the cassette. The heated press heads are moved from a standby position remote from the resin tube to a clamping position for clamping the tube. The heated press heads are then lowered a predetermined distance from the clamping position in order to pull the resin bag and move the heated press heads to a fusing position for fusing said tube. The heated press heads are lowered a short distance from the fusing position and the heated press heads are moved to a separating position for separating an individual bag from the resin tube.

  • Patent number: 4785611
    Abstract: Apparatus, particularly, for packing egg cartons into wire baskets includes a movable tray for delivering cartons to a basket filling station where the cartons are lowered into the basket. Tines support the cartons after the movable tray is withdrawn and a movable press urges the cartons downwardly onto the tines while the tines move downwardly. The sequence is repeated and layers of cartons are progressively added to fill the basket. A sensor determines when the baskets are full and removes full baskets and replaces new baskets for filling. The basket filling station is fed from multiple filling trays fed by multiple conveyors.
