  • Publication number: 20220081145
    Abstract: A semi-automatic case handling machine includes a case holding and forming section with laterally movable spaced apart walls, bottom major flap kickers movable with the walls, and a bottom minor flap kicker movable axially. A case sealing section of the machine includes a bottom taper for taping bottom major flaps, an upper taper for taping upper major flaps, the upper taper movable vertically, and a pair of spaced apart conveyors for moving cases past the bottom taper and the upper taper for taping, wherein the spaced apart conveyors are movable laterally. An adjustment system includes a memory storing a plurality of machine set ups, wherein each machine set up includes data corresponding to (i) lateral positions for the spaced apart walls, the spaced apart bottom major flap kickers and the spaced apart conveyors, (ii) axial position for the bottom minor flap kicker and (iii) vertical position for the upper taper.

  • Patent number: 7555874
    Abstract: A case sealing apparatus includes a frame structure including a case conveyance path extending from a case infeed station to a case outfeed station. First and second side conveying units extend between the infeed station and the outfeed station. The first and second side conveying units are moveable toward and away from the conveyance path for engaging opposite sides of cases to move cases of various widths from the infeed station toward the outfeed station. A lower tape head assembly is positioned along the conveyance path to apply tape to case bottoms. The lower tape head assembly is movable between a lowered position for taping and a raised position for changing tape. An upper tape head assembly is positioned along the conveyance path to apply tape to case tops. The upper tape head assembly is vertically movable to accommodate cases of various heights. A control system controls movement of the first and second side conveying unit, the upper tape head assembly and the lower tape head assembly.
