Safety at high speed with igus e-chain in linear motor robots

Twice as fast and half as heavy: this is what makes the linear motor
robot from Fibro Läpple Technology (FLT) different from other solutions. In
order for the linear robot to be able to get production up and running quickly
and reliably, a compact, durable and quiet energy supply was required. A
side-mounted igus energy chain system with pre-harnessed chainflex cables
proved to be the optimal solution.

Linear robots are the automation tool of choice for machine or press
loading, order picking and high-bay warehouse loading or even for transport and
handling tasks. Due to the demands of production for faster, more intelligent
and economically profitable solutions, Fibro Läpple Technology has developed a
linear robot that helps maximise production performance.

Featuring a new carbon design, the linear motor robot saves up to 50% in
weight compared to conventional solutions. The weight reduction enables twice
the speed, accelerations of up to 26m/s_ and twice the positioning accuracy.
Instead of a rack and pinion drive, the designers chose a linear motor because
it allows very high dynamics.

An unsupported igus energy chain from the E4.1 series ensures secure
energy supply for the z-axis. The integration of a suitable energy chain
solution in the compact installation space of the x-axis was a challenge
because a classic gliding or unsupported solution was out of the question due
to the high forces.

“Together with igus, we, therefore, decided on a side-mounted energy chain,”
explains Boris Bind, Head of Mechanical Design and Development at Fibro Läpple

Complete energy supply system
directly from a single source

An E4.1 series energy chain is used with additional sliding elements
that further reduce wear. The designers also chose igus’ pre-harnessed
chainflex cables – so-called ready cables – that are specifically designed for
use in the energy chain; thanks to extensive testing in the company’s own
3,800-square-metre test laboratory, the cables come with a guarantee of 36
months. The complete system is housed in a special guide trough, which further
minimises noise and increases the reliability of the system.

All igus products are available from Treotham.
