Dipl. Ing. Kai Vogel Kai is director, co-owner and founder of Viprotron GmbH located in Pfungstadt / Germany. Since 2004 his company is well known for innovative glass quality scanning technologies. Viprotron is today the leading supplier for high performance inspection systems for the architectural glass processing industry. Their Quality Scanner 3D devices “Made in Germany” are installed worldwide in all big and leading glass processing players.
There are currently more than 300 of our scanner systems operating in the glass industry worldwide, actively providing reliable quality control. The innovative image processing systems are installed by us and are adapted to the local individual processes within the production line. Once installed the systems ensure a high quality within glass production and processing, as well as saving time and money through the optimization of the production process. Most importantly, they allow our customers to succeed in the continuously increasing quality expectation of their market.
This efficient quality control machine is incorporated directly after glass washing and detects reliably all different types of glass defects – Making it ideal for a profitable glass production and processing. The Quality Scanner reliably detects bubbles, scratches, fine streaks and hairline scratches, at the same time it ignores dust or smallest dirt contamination. The machine consists of up to three, independently operating detection channels. Each channel scans the glass from a different angle and under different light circumstances, while it is being transported at top speed through the Quality Scanner.
The device is positioned in the cutting area, and identifies defects in unwashed glass. Already cut glass with defects can be taken out of production, before it is processed any further, or with the help of a reoptimization of the cutting plan waste areas or possibly small glasses can be positioned on the defects.
This range of performance makes the ECO Scanner ideal for the control of e.g. grinded glass directly after having passed a washer. So it secures a good glass quality or the chance to scrap defected glass before adding more value to it. Due to the mentioned high degree of standardization and a revolutionary working principle a price level has become achievable, which is far below the modular Quality Scanner series. In dissected production structures a central control of of glasses is impossible. Due to the price level of the single devices it is possible to implement quite a few scanners with a total investment still allowing a quick payback.
Anisotropies, also known as iridescence, present as dark circles, spots or stripes in the glass that are visible in polarized light, from certain angles or through polarized sunglasses. The visual effect is caused by different tensions in the glass, mostly resulting from the tempering process. As option in addition to measuring anisotropies, the scanner can detect white haze on the glass, which can be caused by dust, rollers or other factors in the furnace. The haze detection allows operators to know exactly where they must rework the glass to ensure a clean surface before sending it to the next processing stage or the customer.
At the same time, the machine documents all quality relevant results. This efficient final quality control can be integrated within the tempered glass production as well as at the end of the insulated glass production line. This allows you to further reduce your claim costs, secure your in time delivery and to be always prepared for the worst case scenario.
Furthermore, through the exact, visual localization of the defects, it is practically impossible for your employees to overlook the defect, as the LED-based Defect-positioning indicator is integrated directly into the inspection area.
The sensor can also be used for single panes to correct wrongly positioned glass in time.
