Baumer hhs, based in Krefeld, Germany, has introduced the Xcheck DCM (diecutting monitor) – its latest-generation camera system for monitoring product mix-ups in sheet-fed diecutters. This new quality control system can reliably read and decode not only 1D barcodes, but also 2D data matrix and QR barcodes, giving the Xcheck DCM a unique selling point in the market.
Two-dimensional data matrix and QR codes offer the advantage of storing a lot of data in a small area. They take up very little space; for example, on the glue flaps of pharmaceutical or food packaging. Compared to conventional 1D barcodes, they can be of lower contrast and are readable even if parts of the code surface are damaged (max. 30%). They also can be read in any position. These advantages increase reliability in reading the codes, and therefore in the overall process of monitoring product mix-ups.
“Our new SmartCam DCM works with monochrome detection, which permits extremely fast decoding and analysis of 2D codes. If a wrong sheet is detected, the Xcheck DCM can stop the flat-bed diecutter before the sheet reaches the grippers of the feed unit. The machine operator can remove it from the feeder table and immediately restart the diecutting process. In short, the Xcheck DCM rules out the risk of diecutting the wrong sheets and of these blanks advancing to your folder gluer,” said Ralf Scharf, folding carton business development manager at Baumer hhs.
Because the SmartCam DCM is a matrix camera, it can reliably read codes even if sheets are still moving slightly. This means the Xcheck DCM is also suitable for use in the newest diecutters, which are equipped with register systems that position sheets while they are in motion.
The Xcheck DCM can monitor product mix-ups from top or bottom. The latter configuration is required, for instance, when processing blister packs with back printing, pharmaceutical packaging with inside printing or laminated and printed microflute. For these applications, the system can be flexibly adapted to customer needs. The same applies to sheetfed diecutters with dynamic feed systems. Finally, the new camera can easily be integrated in existing diecutters as a standalone system to monitor product mix-ups. In this case, the SmartCam DCM can be flexibly positioned using machine-specific adjustable crosspieces.
