Igus has unveiled a new, low cost, lightweight version of its multi-axis Energy Chain for robotic applications. The original, Triflex R enclosed , was introduced just over a year ago by igus and is currently used by companies including Bayer and Daimler Chrysler.
Due to its round-shaped design, Triflex R glides around the outer contour of a robot, without becoming hooked in and jammed.Triflex R is available in four sizes and performs even complex multi-axis handling tasks reliably.
The modular, lightweight, long-life Energy Chain has been developed for a wide range of different applications. These include tool changers, calibration and automatic image processing equipment, laser, adhesive or handling applications, which often involve inserting large numbers of thin initiator cables.
Shortening and lengthening optionsUsers can shorten and lengthen the Energy Chain at virtually any point. David Chapman, Managing Director at igus UK, explains, This not only guarantees variability, it means there is no waste whatsoever, which is just one benefit of this extremely light and thus cost-optimised 3D energy supply system.
Triflex R light also does not need any additional reinforcements, such as steel ropes.Tension-proof thanks to designThe so-called trailer design principle guarantees a high degree of tension resistance and works the same as an automotive trailer coupling.
Once locked in place, ball and ball socket form an extremely mobile connection, which combines smooth movements in all three axes and an optimum flow of force. Chapman explains:
The Energy Chain has to be able to follow specific handling movements in all axes over a long time. Longitudinal axis torsion of up to +/- 380° per metre is possible. Thanks to the durable inner fastening points, Triflex R light provides a minimum bending radius (radii: 58, 87, 110 and 145 mm), which means cables can easily cope with both radial and torsional movements.
This, coupled with its smooth, inner contour, results in a significant reduction in cable stress and prolonged cable service life.
Thanks to the EasyChain principle developed by igus - an opening the cables are simply pushed in to - the Energy Chain is easy to fill. The cables are inserted quickly through elastic, easy to open brackets and can be pulled out again manually in the same way.
After the cables have been inserted, the overlapping brackets automatically return to their initial position. For users, this quick assembly and dismantling method means time is saved and costs are thereby indirectly reduced.
One crucial advantage of the new modular Energy Chain is all the cables remain visible over their complete length, making regular inspection much easier.If jamming occurs, the spot affected can quickly be localised inside the hose.
The connecting elements for Triflex R also fit the new light version (complete with integrated strain relief and intermediate fastening devices), as does the heat protection hose (protects from welding and metal splashes up to 600° Celsius) and other components.
The enclosed version of Triflex R was awarded the iF Design Award 2004. The new Triflex R light could well mean another industry prize is in the pipeline for Igus.
