Detecting black cartons on a black conveyor belt

Description

In one particular application, matt black cartons with a thickness of approximately 2 mm are located on a black, rubber conveyor belt. A suitable sensor is to detect printed cartons from a distance of 20 mm above the conveyor belt. Important in the choice of sensor was very good background suppression and color independence.

Solution

The HRTL 3B diffuse reflection light scanner is used. This scanner ideally satisfies the requirements and reliably detects the matt black cartons.
