Vision technology has a crucial role to play in offering manufacturers in the food industry a competitive advantage. One important area is packaging, where both the quality of the packaging itself and the markings on it need to be checked. TriVision, based in Odense, Denmark, has developed two vision-based systems featuring vision components supplied by STEMMER IMAGING, which provide 100% inspection of packaging at the manufacturing stage and of the final product.
Europe's leading machine vision technology supplier STEMMER IMAGING ended its business year 2016/17 on 30 June 2017 with a turnover of 88.7 million euros and an exchange rate adjusted growth of 6 percent. After 44 years, the company's founder Wilhelm Stemmer is handing the company over to proven successors.
At the end of the financial year 2016/17, AL-KO AG acquired 75.04% of the shares in STEMMER IMAGING GmbH from the company's founder Wilhelm Stemmer. In the following interview, Wilhelm Stemmer and the two newly appointed managing directors Christof Zollitsch and Martin Kersting explain the reasons for taking this step.
Optics and illumination play a critical role in optimising the imaging conditions for machine vision measurement. Even the seemingly simple act of adjusting the iris (aperture) of a lens affects several parameters in the imaging system. There are a number of ways of adjusting the iris, but the Precise-iris (or P-iris) method offers significant benefits.
The Munich-based AL-KO AG, parent company of the internationally active AL-KO KOBER SE, has as of today acquired 75.04% of the shares in STEMMER IMAGING GmbH from the company's founder Wilhelm Stemmer. The successful management team acquired a share of 24.96% in the company as part of the transaction.
Inspection is a critical component of HACCP programs in the food industry. Hyperspectral imaging now provides a powerful complementary approach for the machine vision engineer. Its ability to identify differences in the chemical composition of organic materials opens up major new possibilities for detecting impurities in food products. Most importantly, systems are now available that operate in real time, allowing them to be used on high speed production lines.
Lighting solutions have become a lot more flexible with the recent advances in LED technology. Not only do you have much finer control of them, but the way you can control them is a lot more advanced too.
In the first of our three part series we’ll be looking into simply plugging in a light, some of the differences between LEDs and Fluorescents, and using lights that have built in drivers and controllers.
