• Entwicklung eines Automatisierten Prozesses zum Handhaben und Verschweißen von Bewehrungsstäben
• Inbetriebnahme des Prozesses an einer hochmodernen Roboter Schweißanlage
• Validierung und Evaluation des Prozesses

Motivation:

In concrete construction, reinforcement is required to absorb tensile stresses. For this reason, steel reinforcement bars are usually embedded in the concrete. In 3D concrete printing, new methods are needed for integrating the reinforcement. One approach is to weld small pieces of reinforcement together step by step to build up a steel structure.

Your tasks in this thesis:

• Developing an automated process for handling and welding reinforcing bars
• Commissioning the process on a state-of-the-art robotic welding system
• Validating and evaluating the process

• Entwicklung eines Konzepts zur Regelung eines Betonvolumenstroms mit einem gravimetrischen Messsystem
• Implementierung der Prozessregelung in einer Beckhoff SPS Steuerung
• Validierung und Evaluation der Prozessregelung mit Wasser als Medium

Motivation:

In 3D printing processes, it is very important to strictly monitor and control all process parameters. In the shotcrete 3D printing process, a large number of process parameters are important. Many of these can be measured and controlled using state-of-the-art technology. However, the concrete flow rate presents a challenge. For this reason, a flow measurement system in the form of a scale (gravimetric) has already been developed. It is now important to feed the measurement data from the scale into a process control system within a PLC.

Your tasks for this thesis:

• Developing a concept for controlling a concrete volume flow using a gravimetric measurement system
• Implementing the process control system in a Beckhoff PLC
• Validating and evaluating the process control system using water as the medium
