KQ‑VD720 Camera Detection System: Multi‑Function Inline Inspection For Folder Gluer

Many packaging converters rely on manual spot‑checks on folder‑gluer lines, yet human inspectors cannot keep pace with high‑speed runs. Missed glue gaps, print blemishes and unreadable barcodes slip through, bringing rework waste, customer complaints and costly product recalls. The KQ‑VD720 camera detection system addresses these real‑world production headaches with one unified inline vision unit.

Three practical inspection modes cut the need for multiple separate sensors. Template‑based image matching compares every passing carton against a saved good sample, catching glue defects, tape offset and print imperfections. 1D code verification stops product mixing, while 2D code decoding handles QR, DataMatrix and PDF417 for full traceability, well suited for EU pharmaceutical carton requirements.

Built for real‑world workshop conditions, the system completes frame analysis within 10‑20 ms. A minimum shutter of 15 μs prevents motion blur at line speeds up to 400 m/min. It tolerates product vibration from 10‑500 pixels, a common issue on ageing folder gluers. Camera objective distance adjusts from 100 mm to 999 mm, giving installers flexibility for new‑machine fitting or retrofits.

The integrated touch screen simplifies day‑to‑day operation for line operators. Staff store hundreds of product recipes, pull up defect images directly on‑site and export inspection logs without extra programming work. Standard IO outputs connect seamlessly with piston kickers or rotary ejectors, forming a closed‑loop quality workflow to reject non‑conforming cartons automatically.

Unlike single‑function glue or barcode sensors, this vision system merges glue monitoring, print inspection and multi‑code validation in one station. It removes manual sampling burden, stabilises output quality and builds audit‑ready traceability data for food, cosmetic and pharmaceutical packaging jobs.
