"We do vision systems on the market and we contacted several companies. All except the Keyence declined in encountering our speed requirements, which allow a window of only 150 ms to inspect each stack."
"For us, broken biscuits are a serious defect. We do not just increase the perception that our customers have in the quality of our products, but we also want to eliminate the risks of the packages that are improperly sealed because of biscuit pieces that get in the way," explains Fabien Ployon, Manager Production site of Nutrition & Santé in Annonay, France. "We do vision systems on the market and we contacted several companies. All except the Keyence declined in encountering our speed requirements, which allow a window of only 150 ms to inspect each stack."
"We need a detection solution that can handle large amounts of biscuits that are processed every minute, and operate 24 hours. We installed and programmed the vision system CV-5000, with the help of the technical department Keyence. The detection / edge position is performed by two cameras placed about 20 inches above the biscuits in each row. A program must be configured differently for each thirty shapes and sizes transmitted in each row."
"The detection / edge position is only one of 19 with inspection tools available via the vision systems of Keyence CV-5000. Each inspection tool makes it possible to configure a detection application in a fast and simple way. Despite having no previous experience in vision machines, systems CV-5000 were easy to install and use. I took some time to optimize it for our needs, but we are now familiar with it and have since embarked on a process of continuous improvement," adds Ployon. This application of cookies inspection was made ??possible by the processing speed of the CV system -5000 Keyence, one of the independent powerful vision systems on the market. For example, it allows 1 million pixels that are processed at 20.5 ms. Such processing power also makes it possible to perform multiple inspections in the process thanks to its repeatability without parallel (seven times greater than today's standards) and image processing tasks that optimize the accuracy of the inspection.
The CV-5000 series are controlled by a mechanism processing color images at high speed, and a high speed CPU of RISC (Reduced Instruction Set Computer, computer reduced instruction set). Both are supplemented by two DSPs (Digital Signal Processors, Digital Signal Processors) designed specifically for image processing.
All models of HP-5000 series four processors use these to achieve faster processing speed - about twice that of the main models on the market. The system is also equipped with a dual memory buffer that allows input from the next trigger while the image is being processed. "View the system CV-5000 working faster than our lines, gives us a definite edge. It works seven days a week, and we are pleased with its reliability detection and stability," concludes Ployon.
For over 30 years, the Nutrition & Santé was guided by the very simple idea that what we eat affects our health. The Nutrition & Santé Group is present in all distribution channels in key segments and organic and healthy foods. The group has Gerblé, Isostar, Gerlinéa, Milical, Modifast, Pesoforma, Bio Cereal, Soy and other high end brands to increase their exports.
These strengths have consolidated the group as one of the most active in five segments - everyday healthy foods, nutritional products for weight loss, sports nutrition and organic food. In 2011, the group employed 1,100 people at its production sites specialized and operated a distribution network in over 40 countries.
