Bulk reading of stacked returnable containers during transport

On conveyor lines in distribution warehouses and factories, the task of reading barcodes on stacked returnable boxes or containers one by one is time-consuming and often becomes a productivity bottleneck. This application dramatically improves the efficiency of logistics processes by reading multiple barcodes and 2D codes affixed to the sides of stacked containers transported at high speed with a single code reader all at once.

What makes this batch reading possible is KEYENCE's SR-5000 Series logistics code reader. With its overwhelmingly wide field of view and long-range performance, it can cover a wide area with a single unit where multiple readers were previously required. It can scan multiple labels at different heights and positions at once. Furthermore, its autofocus function instantly tracks variations in the distance to the containers, enabling stable reading at all times without the hassle of focus adjustment.

This solution accelerates the automation of receiving/shipping management and inspection work, and significantly improves traceability. It also contributes to simplifying the equipment configuration and reducing the risk of line stoppages due to reading errors, providing an optimal solution for productivity improvement.
