Label Detection
PRIMARY PACKAGING
In high‑speed labeling machines, reliable detection of printed contrast marks is essential for accurate label positioning in primary packaging processes. Variations in label design, color, material or machine speed can easily result in missed marks, incorrect label placement and increased scrap.
A contrast sensor continuously monitors the moving label web and reliably detects the contrast difference between the mark and its background. The resulting fast and stable signal triggers label dispensing, cutting or wrapping at exactly the right moment. This ensures consistent labeling accuracy, faster format changes, stable operation at high speed, reduced downtime, and improved OEE in packaging machines.
Key benefits
-
Accurate and repeatable label positioning
Reliable mark detection ensures labels are consistently applied in the correct position, minimizing misalignment, rejects and rework. -
Stable performance at high speeds
Fast response times enable dependable operation in modern labeling machines with very high throughput, without missed marks or timing drift. -
Robust detection on challenging materials
Contrast‑based sensing delivers stable signals even on glossy films, printed liners or low‑contrast label designs, preventing false triggers and unplanned stops. -
Fast and flexible format changes
Simple adjustment to different marks, colors and label layouts reduces setup time and supports frequent product changeovers. -
Improved OEE and process reliability
Fewer labeling errors, less waste and reduced unplanned downtime directly contribute to higher productivity and more predictable packaging performance.
