Device for measurement of returnable packaging e.g. bottles, boxes and in boxes with bottles on transportation devices has virtual illumination surface plane parallel to transportation device

摘要

A cylindrical reflector (6) is arranged parallel at given distance over a transportation device (2) and the cylinder reflector (6) passes an object (9) in its measurements of the quarter circuit radius. A quarter-circular arc (7) with a circuit centre (8) is in the optical axis. Boxes (9) or bottles (10) project on the transportation device (2) and the virtual illumination surface plane is parallel to the transportation device (2).
