Reading stacked barcodes on a reel by presenting it to the reader

Improving the efficiency of reel picking and product verification tasks on electronics manufacturing lines and in warehouses is a significant challenge. In particular, the task of an operator reading multi-level barcodes or multiple QR codes on a reel while holding it is time-consuming and often becomes a productivity bottleneck.

The KEYENCE logistics code reader, SR-5000 Series, provides an effective solution to this challenge. By installing the reader as shown in the image, operators can complete hands-free reading simply by 'presenting' the reel in front of the reader. The SR-5000 Series boasts an ultra-wide field of view and overwhelming reading depth, instantly recognizing codes over a wide area without requiring precise positioning. It reliably reads even moving reels, so there is no need to stop work.

Furthermore, it can read multiple codes, such as multi-level barcodes and various codes printed on a label, all at once, significantly reducing work time. This 'presentation reading' verification system prevents human error, improves traceability for parts replenishment on SMT lines and inventory management, and greatly contributes to the productivity of the entire factory.
