Steel Coil Labeling System (Robot, Gantry and Hot-Coil Tag Options) | Packway, Shenzhen, China

Packway's Steel Coil Labeling System prints and applies identification labels to steel coils automatically. It is offered in three versions: a six-axis robot unit, a gantry (fixed-station) unit and a high-temperature hanging tag unit for hot rolling lines.

The robot version uses 3D vision to find each coil and correct the label position, then checks the printed label with a code reader. The gantry version suits single-specification, high-volume lines, while the tag version fits hot coils where paper labels cannot be used.

Key Features

• Six-axis robot handles coils of different diameters and heights
• Thermal transfer or direct thermal printing of coil number, specification, weight and QR code
• 3D vision positioning and correction on the robot version
• Code reader checks each label after application; failed labels trigger an alarm, then reprint and reapply
• Fencing, emergency stop and PLC or robot controller for safe operation
• Metal tags (stainless steel or aluminium) for hot rolling lines instead of paper labels
• Optional high-temperature insulation on the robot version

Frequently Asked Questions

• Which version suits mixed coil sizes? The six-axis robot version, which adapts to different coil diameters and heights and labels the end face, side face or radially.
• Which version is fastest? The gantry version runs at 0–8 pieces/min, up to 480 coils/hour, at a fixed station.
• Can it label hot coils? Yes, the hanging tag version applies stainless steel or aluminium tags on hot rolling lines at 550–800°C.
• What should I send for a quotation? Send the coil diameter and height range, coil weights, line temperature, label or tag type and size, labelling positions, target coils per hour, and any MES or data interface needs.
