The future is made of wood - sustainable and energy-efficient. Ultra-modern prefabricated houses, like those of the manufacturer FingerHaus from Frankenberg (Eder), are on the rise. Demand is high in an industry that is booming, but simultaneously being hit by a shortage of skilled employees. The burden on existing staff has to be eased as much as possible so that they can be used exclusively for complex tasks, while the focus remains on maximum quality through high process reliability. In order to meet these challenges, BETH Sondermaschinen GmbH has developed and implemented a comprehensive plant concept that includes both, the semi-automated production of the wooden frameworks and the automated paneling of wall elements. 3D camera systems from phil-vision are used for this purpose. The core element of the system is the robot cell for automated paneling of wall elements. Up to now, the paneling of wall elements made of timber and plasterboard was carried out by employees on assembly tables in the production line, and the subsequent fastening was done with hand-operated staplers.

The wall elements were then transferred to a buffer system. In the future, a 50-meter-long line with a width of approximately 10 meters will offer maximum flexibility for paneling with standard dimensions and special geometries, including feeding and transfer to the next production step. Automated paneling is possible for geometries from 80x250mm to 1250x3000mm.
The different sheets are provided lying on stacks, whereby the sheets for one wall element form a coherent stack. A robot with a vacuum gripping system removes the sheets and positions them precisely on the timber frame. The integrated 3D camera system identifies the sheets. Automatic fastening of the two different panel types is performed by the robot using a clamping device.
The result of the BETH Sondermaschinen GmbH project is a highly precise paneling system that also enables efficient cooperation between employees and robots thanks to intelligently designed safety areas. A central, user-friendly cell control system enables the control of individual processes for maximum flexibility in case of necessary intermediate work steps.
It is worth highlighting the small but important details of this system, which has only been possible through close cooperation with FingerHaus staff on site: existing work processes were analyzed, improvements identified and a customized automation solution was developed. Whether it is the efficient use of the existing production space, the operability of the robot in individual processes for more flexible cooperation with the workers on the machine or simply the fact that process reliability is improved - with this system, FingerHaus' production is state-of-the-art and ideally equipped for the future.
Friedrich Köster, Managing Director of BETH Sondermaschinen GmbH summarizes the cooperation with phil-vision in this project as follows:
"Due to the essential importance of machine vision for the functionality of the entire plant, we were looking for a powerful partner in this field, which we found in phil-vision.The experienced experts provided us with the best possible advice regarding the feasibility of our idea, carried out extensive tests for us and put together the optimum camera technology for us, which proves itself every day in practical use at our customer FingerHaus."
