The construction industry is considered as one of the largest consumers of resources worldwide. Therefore, new environmental friendly production processes in the construction industry are crucial for climate protection in the coming years. Additive manufacturing with wood offers a promising solution. Individual Layer Fabrication is considered as a new additive manufacturing process with wood. In this process, objects are constructed by laminating individually contoured wood-based panels. The production of the wood-based panels is automated, but the panels are manually stacked and glued together. This causes potential errors and is timeconsuming. In order to auto-mate these two process steps, an end effector is needed that can take over the handling and the lamination task.
The aim of this thesis was to develop such an end effector. The individual tasks of the end effector were separately worked on. Handling is considered as one of the main tasks of end effectors. Ac-cordingly, a large number of grippers are offered in practice. A vacuum gripping system is suited best for handling the wood-based panels. During the development of the handling system, different vacuum gripping systems were first developed and examined. Based on this investigation, a flow gripper was chosen. Due to the high volume flow of the flow gripper, plates of individual geo-metry as well as plates with particularly rough surfaces can be handled. The development of the application device for automated adhesive application was carried out in short iteration cycles. For this purpose, a first application device with the time-pressure dosing method was developed, tested and then optimised. A pull-back valve was integrated into the final application device to enable reproducible adhesive application. The system properties of the application device were then examined in more detail.
Both systems were attached to the guide gear of a gantry robot. The resulting end effector enables automated handling and lamination. The application of the end effector is limited to aligned fullsurface panels.
