Zalando deploys real time barcode readers

The new reader has been able to measurably increase the reading rate on the linear sorter. The image-based devices reduce extra work by means of RTM (a real-time monitoring function) and increase the efficiency of article picking.

Zalando has added four stationary image-based Cognex DataMan 503 barcode readers to the linear sorter at the item picking warehouse. These are intended for reading differently oriented barcode labels in rapid succession. The DataMan 503 devices achieve higher reading rates than systems that are only laser-based, especially with difficult codes.

Laser-based systems generally do not have monitoring and analysis options to introduce optimisation measures, for instance, in case of diminishing print quality. On the other hand, with RTM all important parameters are visible immediately, says Cognex.

RTM is used for determining reading rate and enables automatic analysis using image processing algorithms of Cognex, thus facilitating troubleshooting and contributing to optimisation of the processes.
