Reading items on a hanger conveyance system while in motion

In Garment on Hanger (GOH) systems in the apparel industry and cleaning plants, reading barcodes on tags attached to moving clothes is a critical challenge for automation. Glare from vinyl packaging and misalignment of tags due to swaying during transport would cause reading errors with conventional code readers, leading to stoppages of automated sorting lines and shipping mistakes.

KEYENCE's SR-5000 Series logistics code reader was developed to solve these problems. Its ultra-wide field of view and great depth of field allow a single unit to cover a large area. Even if the tag positions vary on the conveyor, it instantly captures the code without refocusing. Furthermore, its unique image correction algorithm accurately restores code information even under adverse conditions such as reflections through vinyl, wrinkles, and faded print. It captures fast-moving objects without fail, achieving extremely stable reading.

This high-precision reading technology dramatically improves the automation of inspection and sorting processes and reduces human error. It is a solution that contributes significantly to labor savings, productivity improvements, and the realization of reliable traceability management in logistics warehouses.
