Precise detection of print marks

Wrapping machines use packaging materials on a roll, e.g. films. To cut these in the correct location, the cutting position is indicated by a print mark on the film. To ensure optimal sensor operation and to avoid scrap when changing over the foil, it is important to be able to quickly and precisely adjust the sensor at foil changeover. The KTS Prime smart sensor continuously checks for correct alignment of the sensor with the print marks during changeover, and reports the current alignment quality via the integrated display and also via IO-Link to a panel attached to the machine. This enables the correct adjustment of the sensor to be continuously monitored during machine operation.
