ABSTRACT:
A stacking packaging machine and a process for stacking and packaging resilient workpieces. The workpieces are usually rolled paper products. The machine is comprised of an input conveyor, an elevator, cams, workpiece holders, a packaging film feeder and an output conveyor. A first group of workpieces is placed upon the elevator by the input conveyor and the elevator is lowered. The workpiece holders are brought into place. A second group of workpieces are fed into the holders and held above the first group. The elevator begins to rise and the second group of workpieces are released. The stacked workpieces rise on the elevator toward the output conveyor. Packaging film is fed over the stacked workpieces. The film drapes over the workpieces as they rise preventing any workpieces from falling off the stack. The workpieces enter the output conveyor and are moved to final processing. The timing of the whole sequence is controlled by the cams.
