Low-Flow Palletizer loads cartons at ground level by arranging and then feeds the cartons into a stacking platform that can be elevated. Then the cartons will be stacked layer by layer on the pallet by vertical movement. Since the stacking platform will be elevated once after stacking every layer. The higher the stacking height is, the longer the duration of movement it takes. Therefore, the speed of a Low-Flow Palletizer will be lower than that of a High-Flow one. However, due to lower height for the carton feeding and carton arranging for Low-Flow Palletizer, it will be more convenient for the Conveyor interlocking and troubleshooting.
