Label detection

When packaging drugs, correct labeling is an important criterion. Among other things, serialisation data and barcodes must be applied correctly to the label to enable subsequent logistics processes and goods issue in the pharmacy.

To check the complete and correct positioning of the label, the smart colourSENSOR CFO100 colour sensors from Micro-Epsilon are used. These check the presence and correct position of the labels. For this purpose, the CFS4-F30/90-M sensor is mounted in the labeling machine at a distance of 5 mm above the boxes. The sensor receives the light and passes it on to the controller of the colour measuring system via the optical fibre where the signal is evaluated.

The digital switching output of the controller passes the OK/NOK value directly to the machine control system. If the sensor detects that labels are missing or have been applied incorrectly, the faulty packs are sorted out directly by machine and then relabeled.

The smart, accurate colourSENSORs from Micro-Epsilon impress with their high colour accuracy and repeatability. Since they precisely detect the packages at high belt speeds and enable reworking on the fly, they are ideal for 100% inline inspection. Up to 320 colours in 254 colour groups can be taught in the controller. Operation is intuitive via the web interface. The sensor system for precise label detection (item number 10235596) consists of the CFO100 controller and the CFS4-F30/90 sensor. This combination impresses both by the high accuracy and the attractive price-performance ratio.
