Prospective Technicians Develop New Drive Station at KELLER

For many years now KELLER HCW/DE has been offering pupils and students the chance to carry out project work, internships or research for their thesis under ideal working conditions in an internationally renowned mechanical engineering company. 

„Our specialised departments particularly promote professional performance and commitment shown by pupils and students“, explains J. Schröter, Head of Electrical Engineering, Automation and Process Technology at KELLER. „We develop future-oriented solutions for the ceramic industry in close cooperation with universities and universities of applied sciences. With our KELLER K-matic system we set new standards for automated processes in the heavy clay industry“. As a part of their two-years’ vocational training to become a state-certified technician in information and automation technology at the German Vocational School of the Osnabrück Administrative District, three students, A. Thomann, L. Heseding and D. Forstmann, completed their project work at KELLER in Ibbenbüren-Laggenbeck. From February to March 2013 the group worked two days per week at KELLER HCW. The project titled „Design of a drive station for customer training with Siemens S7 PLC and SEW drive technology“ was successfully completed. U. Wiewel, Head of Technical Training in the Electrical Engineering Department supervised the project team on behalf of KELLER. A mobile training wall shows two drive systems which KELLER frequently uses in its plants. These systems can be alternately controlled from an operating panel on the control cabinet. A touch panel, also located on the control cabinet, continuously displays the current motor values. The necessary visualisation was also created by the project team. In addition, the motors can also be operated by a PLC control system. All inputs required for motor control are made on the touch panel. To comply with safety issues, the installation is provided with an emergency stop facility that shuts off power to the motors. The customer training aims at providing the operating personnel with the know-how they need for maintenance purposes, and, if necessary, with the knowledge to enhance the control programs of their plant. Therefore, the training wall is of modular design where individual equipment can easily be exchanged and thus the installation and the training itself can always be kept up to date. (6/2013)
