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. The control system includes one or more of a multi-size case mode, a case size lock mode and a tape change mode.
