PURPOSE: To provide a pneumatic apparatus for withdrawing and recycling goods from defective blister packages on a blister packaging machine. CONSTITUTION: This pneumatic apparatus is disposed between inspecting and sealing stations on the blister packaging machine and equipped with a housing 12 with a plurality of transversely spaced chambers at its bottom face. A plurality of pneumatic valves 14 are connected to a high-pressure air source and the inspecting station of goods packaging machine and each pneumatic valve 14 has corresponded to each chamber at the bottom face of the housing 12. A plurality of air venturi nozzles 20 have fluidly been connected to corresponding air valves 14 and chambers at their air pressure inlets. Each nozzle has a goods transport conduit connected to its air exhaust end, causing the air venturi nozzle 20 makes partial vacuum in the chamber fluidly connected to this nozzle, when the air valve 14 corresponding to this nozzle is opened, and produces pressured air flow in the goods transport conduit at its exhaust end.
