Abstract
A case magazine and case stripper part of a case opening, loader sealer machine, including longitudinal case slide rails for supporting a vertical stack of unopened, horizontal, flat folded cases, pusher assemblies mounted on a carriage that is longitudinally reciprocated by an endless chain drive to remove the lowermost case from the stack and push the lowermost case forwardly along the slide rails as the carriage moves forwardly, vertical stack support brackets located adjacent the corners of the stack extending upwardly from adjacent the elevation of the slide rails, and being mounted to be selectively adjustably positioned longitudinally and transverse relative one another, and case lifter assemblies mounted on the stack support brackets for elevating that part of the stack that is located vertically above the slide rails more than a preselected distance, automatically allowing the elevated part of the stack to bear against that part of the stack still supported by the slide rails, and thereafter elevate that part of the stack that is located more than a preselected distance above the slide rails. Each case lifter assembly includes a vertical piston cylinder combination that as the combination is operated towards its retracted position, the gripper plate and pad are moved upwardly thereby and are cammed into abutting relationship with horizontally adjacent cases for elevating cases from the part of the stack therebeneath.
