E-CHAIN RETRACTION SYSTEM ENSURES SAFE OPERATION OF ROBOTS

18-04-2019

Industrial robots must work dynamically and quickly in production, so safe and compact guidance of cables and hoses is required. If an e-chain forms a loop in the robot’s work area, it can damage the cables and hoses and lead to machine failure. For this reason, igus has now developed the new low-cost TR.RSEL retraction system, which guides the e-chain in a line on the robot, ensuring trouble-free and fail-safe operation.

Industrial robots for assembling vehicle parts in the automotive industry, for example, work with high rotations and many fast movements. Users rely on e-chains to ensure that cables for data, pneumatic and energy supply are safely guided on the robot. Triflex R e-chains from igus, available through Treotham, are specially designed for industrial robotics and adapt to their three-dimensional movements. 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 robot’s energy supply. For this reason, igus has developed the cost-effective triflex RSEL retraction system for its e-chains, to ensure that they are kept as compact as possible on the robot’s arm. The system prevents the hanging energy supply system from affecting or blocking the robot’s movements, even in highly dynamic applications.

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