Robots: Innovations in energy and data supply

igus has several new developments in power and data supply for robotic equipment on show at the Automatica in Munich. The company has developed a new universal module called Triflex RS, specifically for robotic applications in very cramped conditions. The multi-axis robotic energy chain Triflex RS is always guided parallel and close to the robot arm, preventing a loop forming or cables becoming strained at the robot head. The low-profile module can be mounted directly to the existing fastening points on the robot. The moving end of energy chain is attached to the sixth axis with a mounting bracket. This system allows general movements, so no specific programming is required. Thanks to its compact design, the system can even be used if there is a valve cluster or distributor box on the third axis.

Alongside the new developments in spring rod modules, there are also new special protective jackets now available. They protect the energy chain from liquid metal splashes or other materials. These are important in hot conditions such as in foundries, or for paint or sealing applications. The protective jackets are pulled over the energy chain and held by a Velcro fastener or elastic, thus ensuring the chain's long service life.

Energy supply on the seventh axis

igus have developed the energy chain E4.1 for safe energy supply on the seventh axis. It allows high flexibility and robustness in all applications. Assembly times can be reduced by up to 80 percent thanks to improved opening and separating bridges. A quick-locking feature ensures little force is needed for opening and closing, even for very fully loaded chains. Special design, including the “tongue and groove” link joint improves the self-supporting length by more than 20 percent. The tongue and groove” joint ensures very high rigidity even with strong lateral forces.
