Abstract
A pneumatic apparatus for withdrawing and recycling goods from defective blister packages on a blister packaging machine comprising a housing which is positioned on the blister packaging machine between the detection station and the sealing station and having a plurality of transversely spaced-apart open chambers in the bottom thereof. A plurality of air valves are connected to a high air pressure source and to the blister package machine detection station, and each air valve corresponds to a respective chamber in the bottom of the housing. A plurality of air venturi nozzles are provided wherein each air venturi nozzle is fluidly connected at its air pressure input end to a corresponding air valve and chamber. Each nozzle comprises a goods transportation conduit connected to its air exhaust exhaust end so the air venturi nozzle will create a partial vacuum in the chamber fluidly connected thereto and a pressurized air flow in the goods transportation conduit at the air exhaust end thereof when the air valve corresponding thereto is opened. Upon receiving a signal from the detection station, the pneumatic goods recycling apparatus will pneumatically withdraw the goods from predeterm…
