Scholle IPN rib stacking machine

A PLC controlled stacking machine for thin ribbed plastic strips nominally 300mm long was designed, manufactured and commissioned. The machine receives strips chopped to length from a continuous extruder at nominally 130 parts per minute, stacks them then loads the stacks into magazines mounted on trolleys. The magazines hold about 3800 strips for the next manufacturing process. The machine includes a two stage accumulator, stack transfer and elevation system, stack insertion to the magazine and an indexing system for the trolleys to align the magazine compartments correctly during transfer.
