Bielefeld scientists awarded with the Transferpreis OWL

Decorative veneers beautify our daily live. They are, e.g., covering baseboards and window frames. Up to now, the wrapping of corresponding profiles was a very time consuming process. The setup of the required wrapping machines had to be done manually which could take up to four hours. Scientists of the Cognitronics and Sensor Systems Group at CITEC at Bielefeld University together with the HNI at the University of Paderborn and the wrapping machine manufacturer düspohl developed an automated system to reduce the setup time for the profile wrapping by a factor of 50 to 100. For this innovation the research project "RoboWrap" was awarded with the “Transferpreis OWL 2012”.

On 21st November 2012, the award was bestowed after the four finalists of the competition previously presented their projects to the jury and the audience. After a 45-minute jury session the winner was announced. The Transferpreis Ostwestfalen-Lippe worth 5,000 euros went to the research project "RoboWrap". The project with a total investment volume of 800,000 euros lasted almost two years. 450,000 euros were contributed by the Federal Ministry of Economics. The Cognitronics and Sensor Systems Group (Prof. Dr. Ulrich Rückert) at the Center of Excellence for Cognitive Interaction Technology (CITEC) at Bielefeld University and the research group for Control Engineering and Mechatronics at the Heinz Nixdorf Institute (HNI) at the University of Paderborn as well as the düspohl Maschinenbau GmbH automated the setup process for profile wrapping machines.

Up to now, the system had to be set up manually and readjusted during production to achieve the required quality. This was cost-intensive and time consuming. The newly developed RoboWrap automatically selects the appropriate pressure roll and adjust those optimally according to the current profile. "The set-up time is reduced from up to four hours to two minutes," says Dr. Thorsten Jungeblut from CITEC. Jungeblut together Diplom-Ingenieur Marc Hesse (also CITEC) was responsible for the implementation of a system for the sensor-based measurement of the rolls in the magazines of the machine and the development of an algorithm to derive the optimum roll configuration. They also contributed a graphical user interface for the simple handling of RoboWrap. "The collaboration with the colleagues from the University of Paderborn and the engineering company düspohl was very good and demonstrated the enormous potential of such transfer projects for the region of Ostwestfalen-Lippe," says Jungeblut about the cooperation partners. "Our aim to transfer our research results directly into the machine could be realized," adds his colleague Marc Hesse emphazising the spirit of the Transferpreis. The company düspohl is also very enthusiastic and plans similar cooperation projects for the future.

31 projects had applied for the Transferpreis OWL 2012. Initiators and sponsors of the prize, which was awarded for the fifth time, are the Chambers of Industry and Commerce, the Chamber of Crafts in Ostwestfalen-Lippe, the Initiative für Beschäftigung OWL and the Stiftung Standortsicherung Kreis Lippe. With this price they want to advance the cooperation between industry and science in the region Ostwestfalen-Lippe. Increasing the number of start-ups and keeping young scientists in the region are additional goals. An important criteria for the selection was the economic relevance and the degree of innovation of the project.
