Applications
Wherever systems are moved automatically, it is necessary to uniquely determine their respective posi
-
tions. In addition to mechanical measuring sensors, optical methods are particularly well suited for position
determination as they can be used to determine position without mechanical wear and slippage.
Compared to common optical measurement techniques, the Leuze electronic Bar code Positioning
System (BPS) is able to measure a position with absolute sub-millimeter accuracy, i.e. independent of
reference points. As a result, it is able to provide a unique position value at any time. With the highly flexible
and hard-wearing Bar Code Tape (BCB), the system can even be used without problem in systems with
curves or guide tolerances. And this at lengths of up to 10,000 meters.
The product family of Leuze electronic bar code positioning systems convinces with a variety of advan
-
tages:
• The laser simultaneously scans three bar codes and, as a result, is able to determine the position
with sub-millimeter accuracy. The wide reading field makes accurate position determination possible
even in the event of minor damage to the tape.
• With the systems' flexible depth of field, it is also possible to bridge over mechanical deviations.
• Due to the large reading distance combined with the great depth of field, a large opening angle and a
very compact construction, the device is ideally suited for the conveyor and storage technology
market.
• The BPS devices are capable of simultaneously measuring position and speed and are thus also
suitable for control tasks in your automation applications.
• Using a mounting device, the BPS can be mounted with millimeter accuracy with just one screw. If
mounted using a mounting device, a new device is automatically aligned correctly should it be nec
-
essary to exchange a device (easy-mount).
• The unique labeling of the bar code tape allows the system to be put back into operation without
problem even after a brief voltage drop without, e.g., needing to utilize a reference point.
• The Leuze electronic bar code tape is very robust, highly flexible and, thanks to the self-adhesive
back, can be easily integrated into your overall mechanical system. It can be fit optimally to both ver
-
tical as well as horizontal curved paths and thereby reliably facilitates trouble-free and reproducible
measurement at any point in your system with sub-millimeter accuracy.
Typical applications for the BPS include:
• High-bay storage device (see chapter 5.1)
• Telpher line (see chapter 5.2)
• Gantry cranes (see chapter 5.3)
