Trays of pump housings are loaded into the system where they are de-stacked and transferred to a pick up position.

The previously unloaded tray is positioned next to this full tray so tested parts can be loaded into it.

A Fanuc 6-axis robot with twin grippers picks parts from the tray and loads one of two leak testing stations.

The robot services the two test stations alternately.

On completion of a full tray the walking beam transfer mechanism indexes trays along with the tray full of good tested parts stacked in the outfeed stacker.

The system allows loading of new pump trays and unloading of tested pumps to occur whilst the machine is running.
