Detection of Luminescent Labels on Food Cans with Luminescence Sensors

In the production of canned foods, it must be ensured that every can has a label after the filling process. For this purpose, the labels are given a luminescent marking that is not visible to the naked eye. Two luminescence sensors installed on the side of the conveyor belt detect the presence and correct position of the labels. Different product labels can also be reliably distinguished. If an incorrect label is detected or no label is detected at all, the system automatically ejects this can.

Luminescence Sensors

Luminescence sensors emit UV light at a certain wavelength. If the emitted light strikes a luminescent object, it reflects within a visible wavelength range in accordance with the luminescent substance mounted. The sensors use this effect to make markings on labels visible, for example.
