Germany's Warsteiner Brewery enlisted the help of BHV-Automation to develop a system to track beer kegs throughout the filling process with the capability of 100% accurate code reading. To do so, the system utilized Cognex DataMan barcode readers. This article, which was published on April 1, explains that in the automated process, a label printer first applies an adhesive label with a Data Matrix code to the bottom of an empty keg. After this, a Cognex DataMan 302X ID reader reads the printed label on the keg. DataMan barcode readers allow Data Matrix codes to be read from 10-, 15-, 20-, 30-, and 50-liter kegs that vary in distance from the barcode reader.
