How it works:

From the spiral conveyor parts are moving onto the MRW camera conveyor belt where they are scanned by the MRW linescan camera. Separation and minimum distances are ensured.
Bottoms on "the back" are marked as GOOD, bottoms on "the belly" are marked as BAD.

Next the bottoms pass another test station. A Keyence vision sensor acquires the color determination and examines the longitudinal orientation on the basis of the printed pattern.
In order to cope with the difficult reflective properties of the workpieces, an additional special coaxial illumination was used.

Too close successive workpieces, "belly bottoms" are then blown back into the bowl feeder.
Parts in wrong longitudinal orientation are turned by the turning station.

At the end of the belt the bottoms move into the customers machine.

Always the correct type of part, always in correct orientation...
