ROBOTICS & HANDLING Retraction system for energy chains

Dec 30, 2019

igus has developed a retraction system for energy chains that ensures fail-safe operation of robots in modern factories

igus recently developed the triflex R e-chains that are specially designed for industrial robotics and adapt to the three-dimensional movements of robots. However, with the growing diversity in automated production technology, it is necessary to guide not only electrical and pneumatic cables, but also hoses for bolts, rivets and screws. Since these hoses are not compatible with tight bend radii, a retraction system is required for the energy supply of the robot. For this reason, the company has developed a new, cost-effective retraction system triflex RSEL for its energy chains. This ensures that the e-chain is kept as compact as possible on the robot arm. The system prevents the hanging energy supply system from affecting or blocking the movements of the robot, even in highly dynamic applications. In the worst case, looping would damage the energy chain, the cables and hoses inside it, leading to machine failure.

Due to its standard dimensions and its very compact design, the new retraction system can be mounted directly on the 3rd axis of all common types of robots. This means that all existing triflex R series such as TRC, TRE and TRCF can be quickly and easily converted. The fixed end of the energy chain can be freely selected by the new system. Another advantage by using the linear retraction system is – the user saves additional cable length and associated costs, since no deflection is required. The triflex RSEL is available from igus as a variant with two elastomer bands in sizes 70 or 85.
