An in-line handle leak tester built around a Bosch pallet transfer system.  The system uses a Beckhoff embedded PC as a controller.  Four handles are tested at one time using a pneumatic "bang-bang" mechanism.  Rejects are dropped onto a small roller conveyor.

 

Though relatively simple mechanically, this project broke new ground in terms of error handling and recovery, earning high praise from the customer relative to their other systems.
