In March 1999, the CPS® system was
introduced to conveyor technology. Since then, numerous prodution lines
of various automobile plants and other manufacturing factories have
been equipped with a contactless power supply system. The CPS®
system is used in material handling systems for automobile components
(e.g., engines) or for complete products (e.g., compressors).
Floor skid systems can accomodate
switchpoints or lift stations. All systems are dimensioned so that, if
necessary, additional vehicles can be integrated.
The primary conductor is installed "under
floor," so that crossing traffic of other vehicles (forklifts) is
guaranteed. In many cases, the primary conductor is enclosed in a PVC
profile. Here, the groove of this PVC profile visible from the outside
is not important for power transmission. It is used merely for guiding
the vehicle with the help of a guide roller mounted on the vehicle.
The following features distinguish the
CPS® technology, especially in floor skid conveyors:
- Full functionality even in areas of
curves, switchpoints, and lift stations
- The primary conductor can be installed
out of sight under the floor in any non-metallic floor material.
- The pick-up unit used as the power tap is
mounted on the vehicle for a space-saving configuration.
- For customer-specific power supply for
engines, as well as for the controller and other components (sensors)
on the vehicle, the pick-ups provide different output voltages of 560
VDC and also 24 VDC.
- An integrated, inductive data
transmission, as well as integrated, inductive track guidance, complete
the system. Additional devices along the track, such as data light
barriers, radio transmitters, or guide mechnisms, are then no longer
necessary.
EMC and EMF tested
CPS® components have undergone careful
testing by independent testing laboratories. The system has been tested
for electrical interference emissions, resistance to interference, and
magnetic and electromagnetic fields with respect to worker safety. The
system complies with all conditions in the test regulations.
Permissible values are not exceeded.
Large motion tolerance
The optimum distance between the pick-up
unit and the floor surface is 10-15 mm depending on the configuration.
The horizontal deviation from this position may equal up to +/- 25 mm.
These values permit large motion tolerance for the vehicle and
guarantee reliable power transmission under all operating conditions.
Switchable track sections
For reasons of worker safety or other
operation-specific reasons, track sections must be able to be
deactivated completely. These sections can be switched safely in
the CPS® primary inverter cabinet or directly at the track.
