The
"Triflex R" robot accessory package from the German energy chain
expert, igus GmbH, Cologne
Corrugated hoses can kink and tear. That is why igus developed the 3D
energy chain "Triflex R" for robot producers and users. It is
available in three designs. The first is a closed version to protect the cables
on rough applications, such as welding spatters, chips, and dirt. The second is
the "Easy" version in which the cables are simply pressed into the
chain by hand, finally an easy to handle and install "Light" version
is available.
Guiding
the cables around difficult geometries.
The multi-dimensional, movable robot chain can have its length adjusted
at any time thanks to its modular construction. It can be either shortened or
lengthened at any place. It achieves its high tensile strength using the “ball
and socket” joint. The individual elements are not connected to each other
using extra steel cables similar, but with a simple connection like a trailer
tow bar. This ball and socket design ensures mobility in every direction. It is
possible to turn about +/- 10° per link in the chain. This makes it much easier
to guide the cables around difficult geometries.
No
tangles, no stress with cables
In addition, there is a defined freedom of movement in all three
dimensions. The bending radius is the same in every direction, which also
reduces stress on the chain itself, as well as the cables, and hoses. In
addition, the use of spring-rod modules generates a directed pre-tension. This
makes it possible to create a system where the chain is suspended and doesn’t
get caught up in the working area. igus also offers a "Triflex RS"
set specially for robot applications with limited installation space. This
version guides the energy chain parallel to the robot arm to save space. It can
be mounted directly on all attachment points on the robot. Finally, protectors,
quick attachment systems, and attachment modules for nearly any robot complete
the wide product range.

Extremely fast exchanges of cables: "Triflex R" energy chain,
shown here in the "Easy" version. The cables are simply pressed into
the chain by hand and are always accessible from the outside. This reduces
maintenance and overhaul work and reduces the downtime of the robot.
New bolt connection ("C version"). Here the links of the chain
are connected using a spherical plain bearing for form fitting power
transmission.

Also new:
additional connections ("B version") for up to four times as much
radius stability. The ball and socket connection was altered for this design.
Cables
are easily accessible
igus presented two central innovations for its "Easy" version
at the "Automatica" Exhibition. The "Easy" version allows
the cables and hoses – which are simply pressed into the energy chain – to be
easily visible and accessible from the outside. This makes it possible to very
quickly replace individual cables or the entire hose/cable package if service
is needed. This solution shortens the time needed for maintenance and overhauls
and thus reduces the downtime for the robot.
New:
50 percent higher tensile strength
Firstly, the "Easy Triflex R" is now
available in size 125 with a pinned connection (the so-called "C
version"). This
permits simple installation and removal of the links in the chain. The
connection of the links of the chain is made using a spherical plain bearing –
spherical cap and locking pin – which ensures form fitting power transmission.
The linear tensile force absorption has been increased to 4,000 N. The energychain can now compensate for even greater torsion forces.
New:
four times as stable
Secondly, the "Easy Triflex R" is now available with a further
improved attachment system (the so-called "B version"). This provides
up to four times as much radius stability so that even higher forces can be
absorbed for complicated and restricted movements of the robot arm while still
protecting the cables. The ball and socket connection was altered in the design
for extremely rough applications with high accelerations and very high speeds.
The quadruple increase in the bending radius stability has been demonstrated in
numerous company tests at the igus-Technicum
Center in Cologne
