The motion
plastics specialist igus has developed a lightweight and cost-effective concept
for the automatic retraction of energy chains allowing further advances in
robotics. Besides carrying energy, data and media cables, industrial robots
nowadays also frequently carry supply hosesfor rivets or screws. The new
triflex RSE system prevents looping of the energy chain, allowing these
materials to be safely supplied to the end of the robot arm.
The triflex R series has been
designed by igus specifically for highly dynamic industrial robotic
applications and as a multi-axis energy chain it can move in all directions in
space. The universal triflex chains made from high-performance plastics work in
even the most demanding industrial environments, are easy to install and can quickly
be filled with cables from the outside. They also have high tensile and torsion
strength. "However, since nowadays it is not only just electrical and
pneumatic cables that are conducted on the robot, but also often supply hoses
for bolts, rivets or screws, tight bends or hanging loops can sometimes cause
problems," says Jörg Ottersbach, industry manager for robotics at igus.
"Any reduction in the minimum allowable bend radius of the supply hoses can
lead to a fault, reducing the efficiency of the process. - In the worst case a
rivet or a screw gets stuck in the supply hose, which then leads to a plant
standstill." With its linear retraction of the e-chain, the triflex RSE
retraction system offers an efficient and cost-effective solution that requires
no curve, spring rods or deflecting rollers.
Sleek design with direct control on
the robot
The extremely light system is based
on the proven lubrication and maintenance free drylin linear guide from igus,
where a moving carriage transports the chain on a retraction distance of up to
600 millimetres. Elastic cords pull back the extended chain automatically. Thus
the looping of the energy chain is prevented. In this way the service life can
be significantly increased.
The self-guiding retraction system
is designed for the enclosed or snap open triflex chain versions TRC, TRE and
TRCF in sizes from 60 to 125 millimetres in diameter. They are retained by
means of a mounting bracket and a glide-through bracket on the system, which in
turn can be easily fitted to a variety of robot types. Since the triflex RSE
directly guides and controls the e-chain on the robot and no other deflections
are needed, the required length of the cable and chain is reduced. For this
reason triflex RSE is not only space-saving and light, but is also a
cost-effective solution.
