Igus RSP for robot guidance

The igus RSP (pneumatic retraction system) adjustable retraction system is designed for secure cable guidance and can be used for large arm sizes and complex movements.

With the RSP, the force is generated by a pneumatic cylinder. The system’s retraction force is adjusted by changing the pressure in the cylinder. The force progression remains constant, which the company claims ensures secure retraction of the energy chain in complicated fillings, with cables and hoses in many positions. The RSP is easily attached to various robot models with compact mounting brackets. The systems come in extension lengths from 500 to 1000 mm.

Several designs of robot chains are available: the closed design is for cable protection in harsh applications, such as those involving spatter welding machines, chips and dirt; the easy version is designed so the cables can be quickly pushed into the chain by hand at any time; and the light version is easily managed and rapidly assembled. The tensile strengths are absorbed by the energy chain to increase the life of the cables and minimise downtime.

For robots whose program sequences are frequently changing, alternating or unpredictable, an optional monitoring system is provided. This is suitable for robots steered by cameras or image acquisition systems. A connection to the robot controller or PLC facilitates monitoring; an early warning signal is given when a predetermined tolerance value is about to be exceeded.

The Triflex R multidimensional moving energy chain is used for power, data and media supply. The construction kit is designed for robot users and has about 250 components to guide cables and hoses securely around difficult geometries.
