Examples of a robotic de-palletizer and a robotic magazine loader are described herein. The robotic de-palletizer is configured to remove cases (e.g. HSC (half slotted cases) filled with product (e.g. disassembled cartons)) and to place the HSC on one or more conveyors. The conveyor(s) move the full HSC from the “de-palletizing” area to a magazine-loading area for processing by a robotic magazine loader. In one example of the robotic magazine loader, HSC containing unassembled cartons are removed from the conveyor. The contents of the HSC are added to a magazine feeding a carton assembling and filling machinery and the empty HSC is conveyed to a discard location.
