Barcodes on Cans Read by Barcode Raster Scanners

In the packaging industry, barcodes printed on different cans must be reliably scanned. Triggered by a trigger signal, the cylindrical cans are guided past the scanner at a speed of 45 m/min and are detected. If the scanners are optimally aligned to the desired code types, even varying diameters of the passing objects have no influence on the quality of the scan. The more precisely the scanner is aligned to the codes, the smaller the laser line can be set and the advance speed of the cans can be increased.
