    Color Sensor for Label Inspections

Medication packaging must be properly labelled. Imprinted are serialization data, the bar code and additional information. The correct positioning of the label is also important. Therefore, smart colorSENSOR CFO100 sensors from Micro-Epsilon are used for absolutely reliable label inspection. The colorSENSOR CFO enable 100% quality control and ensure smooth processes in the labeling of pharmaceutical packaging. For this measurement task, the sensor is positioned at a distance of 5 mm above the boxes in the labeling machine. The sensor receives the light and passes it on to the controller of the color measuring system via the optical fiber where the signal is evaluated. The digital switching output of the controller passes the OK/NOK value directly to the machine control system. If labels are missing or in the wrong position, the medication packaging is immediately sorted out by the machine and relabeled. 

Measurement at high speed

The advantages of Micro-Epsilon color sensors are their high color accuracy and repeatability. Therefore, they are ideal for 100% inline control. Even at high belt speeds, they measure precisely and allow rework during operation. Up to 320 colors in 254 color groups can be taught. Operation is easy via the web-based interface. The sensor system also offers an attractive price-performance ratio.
