6-sided reading on a multi-level sorter

In the high-speed conveyance process of multi-level sorters in logistics warehouses and production lines, barcode reading errors are a major cause of reduced throughput. The solution is an automated system that installs multiple code readers on the top, bottom, and sides of the conveyor to read all six sides of an item at once, regardless of its orientation.

This application utilizes KEYENCE's ST Series scan tunnel system. With its ultra-wide field of view and long focal distance, the ST Series can cover a wide area with a single unit, handling various sizes of cardboard boxes, small bags, and irregularly shaped packages on the conveyor. Furthermore, its high-speed shutter and unique algorithm reliably capture codes on fast-moving workpieces, significantly reducing sorting takt time. It achieves stable reading of challenging codes, such as those under vinyl or with poor print quality, preventing shipping errors and contributing to improved traceability. This is a solution that strongly promotes logistics DX and labor savings in factories.
