Reading shipping labels at a parcel delivery hub

In parcel delivery hubs and logistics warehouses, accurately reading the shipping labels on a vast number of packages moving at high speeds on conveyors is key to improving throughput. However, barcode reading errors directly lead to missorts and delivery delays, causing manual verification work and becoming a major factor in reduced productivity. Achieving stable reading is particularly challenging on lines where packages of various sizes and orientations are mixed.

KEYENCE's ST Series scan tunnel system was developed to solve these challenges in logistics operations. With its ultra-wide field of view and long focal distance design, a single unit can cover the entire width of a wide conveyor that would have conventionally required multiple units. Combined with its bulk reading function for multiple codes, it instantly and accurately captures barcodes and QR codes on fast-moving packages.

Furthermore, its unique algorithm stably decodes challenging codes, such as those with reflections from vinyl wrapping or faded print, significantly reducing line stoppages due to reading errors. It promotes logistics DX and contributes to improved sorting accuracy and maximized operational efficiency.
