Top-side reading

Are you facing challenges with reading barcodes or QR codes on the top surface of cardboard boxes on conveyors in logistics warehouses or production lines? For fast-moving workpieces or when boxes are placed inconsistently, reading errors can be a major cause of decreased productivity.

In this application, a fixed-mount code reader is installed above the conveyor to automatically read codes on the top surface of incoming items. This leads to significant efficiency improvements and labor savings in incoming/outgoing inspections and sorting operations.

Utilizing KEYENCE's ST Series scan tunnel system, in particular, solves conventional problems. The ST Series is characterized by its combination of a wide reading area that can cover the entire width of the conveyor with a single unit and a long focal distance that requires no focus adjustment. Therefore, stable top-side reading is possible even if the box size or placement varies.

Furthermore, it supports high-speed lines and has a function to read multiple codes at once, significantly reducing takt time. This also eliminates the need for operators to align the boxes, contributing to a reduced workload. It is strong against challenging codes, such as those under vinyl or with poor print quality, ensuring traceability with a high reading rate and improving logistics quality.
