Double Layer Control of Coffee Capsules Before Filling by Laser Distance Sensors Triangulation

When producing capsules for coffee machines, it must be ensured that only one capsule at a time is inserted into the trays of the multi-lane conveyor belt during filling. For this purpose, one precise laser distance sensor triangulation is used per track, which recognizes whether one or more capsules are positioned on top of each other. Eight sensors simultaneously check the eight tracks of the conveyor belt. Due to their material independence, CMOS sensors reliably switch to capsules of a wide range of colors – even on metallic, shiny capsules.
