6-sided reading before a shoe sorter

On high-speed sorting lines in logistics warehouses and e-commerce centers, especially in the process before a shoe sorter, it is essential to read barcodes on conveyed cardboard boxes instantly and accurately. However, labels are often placed in inconsistent locations—such as the top, side, or front—and reading errors leading to line stoppages and missorts have been a major obstacle to improving productivity.

The solution to this problem is a '6-sided reading (multi-sided reading)' system, where barcode readers are installed on the top, bottom, and sides of the conveyor to capture codes from all angles. By reliably reading 1D/2D codes on any surface without stopping the conveyor, sorting accuracy and throughput are dramatically improved.

KEYENCE's ST Series scan tunnel system is ideal for building this system. A single unit can cover an extremely wide area, allowing a scan tunnel to be constructed with fewer units than conventional systems. This contributes to space savings and reduced installation costs. It achieves blur-free, bulk reading of multiple codes even on fast-moving workpieces. Furthermore, it is equipped with advanced correction functions that enable stable reading even under adverse conditions, such as wrinkled or faded labels and reflections from vinyl wrapping. 6-sided reading using the ST Series maximizes the capabilities of material handling equipment, achieving automation of logistics processes and enhanced traceability.
