Reading packages of varying heights on a pallet during transport

On automated lines in distribution warehouses and factories, managing cargo on pallets transported by conveyor is a critical issue. In particular, problems such as inconsistent label positions due to varying heights of stacked cardboard boxes, and unstable reading of barcodes and 2D codes due to reflections and wrinkles from stretch film, significantly reduce operational efficiency.

KEYENCE's SR-5000 Series logistics code reader was developed to solve these challenges. By combining a long focal length with the widest field of view in its class, it can cover multiple labels at different heights and front-to-back positions on a pallet with a single unit, without needing to install multiple readers. It achieves stable batch reading without stopping the cargo during transport.

Furthermore, with its proprietary algorithm and advanced image correction functions, it maintains a high reading rate even for challenging codes through stretch film and codes with poor print quality. This reduces the risk of line stoppages due to reading errors, dramatically improves the accuracy of receiving/shipping management and traceability, and contributes to maximizing productivity.
