A system’s standstill costs time, money and nerves. To reduce downtimes
and to avoid damages, igus GmbH offers with PPDS advanced and PPDS pro
Condition-Monitoring-Systems to monitor shifting forces at energy chains.
Machine stoppages can’t always be
fully avoided – even with most extensive precautionary measures. When energy
supply systems are open, parts or tools can fall into the chain and block the
motion. The possible consequence: Damages that require partial or complete
replacement of the chain and the guided cables. In these cases to keep damages
to a minimum , igus offers the appropriated “Push Pull Force Detection System”
(PPDS) for such applications. igus could tremendously reduce the space
requirement due to the use of state-of-the-art electronic components: previous
and partly clumsy switchboxes for evaluation units of shrink about 2/3 in size
and price. With it the “brain of the energy chain” now becomes cost-effective
standard equipment.
Reliable prevention of damages
It has been ten years since igus
introduced the first PPDS. Its function: The PPDS monitors occurring shifting
forces at energy chains. If something blocks the motion, shifting forces
increase. From a firmly defined threshold value, PPDS sends a signal to the
system control to stop all motors. This avoids severe damages at the energy
chains and the cables. The field of application of the PPDS family starts at
travels of 10 meters and reaches up to plants with travels of 500 meters and
more.
Compact monitoring of the state for all sizes
To monitor ways between 10 and 100
meters, the especially cheap PPDS basic is part of the igus program since 2012.
It registers shifting forces via two small sensors that are located between the
connecting element of the energy chain and the towing arm. The evaluation unit
PPDS.EU.01 displays the forces, records occurring exceedance of the limit
values and in case of emergency – sends the signal to the machine control. A
complete system inclusively sensors, evaluation unit and connection cable is
available from stock.
For travels of 100 meters and more,
the floating moving ends are used to compensate lateral tolerances during the
floating end drive. For this purpose igus provides the PPDS advanced with a
special sensor variant. This allows reliable monitoring of shifting forces also
in this case. In the heavy-duty area with its very long travels and high
additional loads, igus offers the PPDS pro. It is particularly designed for the
application, controls shifting forces on the basis of position dependent limit
values. Previously an evaluation for the systems advanced and pro, clumsy
switchboxes were used, whereas today thanks to smart electronics, a compact
unit of the protection class IP65 – smaller than a DIN A4 sheet – overtakes
this task.

supply systems are blocked shifting values increase. The new and compact
evaluation unit igus PPDS.EU.01 signals the status at all travel distances so
that all motors can be stopped via the system control. (Source: igus GmbH)
