Visual Detection & Reject Systems

Nowadays, more and more factories adopt Laser Marking machines, or inkjet printers, to improve product traceability. No doubt that equipment can realize automatic coding, marking, and labeling on the production line with high speed. However, double-checking is indispensable to prevent labeling errors. Randomly inspection manually could be a high risk for FMCG manufacturers, since the hundreds and thousands of items run on high-speed production lines every minute.

DANA developed a system to solve this problem. It includes a Vision Inspection system and a Reject system. Every barcode or QR code and other markings will be caught by a high-speed camera and verified. The Reject system can remove the unqualified piece instead of manually operating it.

We call it the fully automatic page-turning inkjet coding system. It integrates an industrial control system, a page-turner, marking equipment, inspection and rejection, and material collection into one unit. It is specifically designed and developed for the page-by-page coding of products such as food and drug packaging, medical devices, etc. It is suitable for various packaging materials like boxes, paper, labels, cards, plastic bags, etc., meeting the needs for page feeding, printing, engraving, and coding.

The machine's operation process is simple and efficient: firstly, the page-turner automatically separates stacked products into single pages and conveys them to the coding area; then, either the inkjet printer or the laser marking machine prints barcodes, QR codes, production dates, and other information on the products; subsequently, the integrated vision inspection system immediately conducts quality checks to ensure the readability and correctness of each code; products that do not meet the standards are automatically rejected, ensuring only those that comply with the standards proceed to the next production stage or enter the market.

Launching this system not only improves production efficiency but also significantly reduces the risk of product recalls and damage to brand reputation due to labeling errors. This fully automatic page-turning inkjet Coding Machine is a great help for enterprises pursuing efficient production and high-quality control.
