The COMPACTplus-XSS/R reliably detects paper rolls and other closed rectangular contours

Leuze: The new COMPACTplus-XSS/R Safety Light Curtains (XSS: eXtended Shape Scanning) are used with roll printing processes. They guard the access area when feeding in rectangular objects, such as paper rolls in the print and paper industry, for example.

Similar to Muting – the properly intended and time-limited suppression of the safety function – the Safety Light Curtain mounted at a tilt detects the paper roll where the rolls are fed in on the basis of its closed rectangular shape, and allows it to pass as an access-allowed object. A person entering the COMPACTplus-XSS/R protective field is detected as an access-denied object on the basis of their contour and their movements, and the dangerous movement is stopped instantly.

This solution reduces the expenses for the user compared with previous Muting solutions, because no separate Muting sensors and Muting indicators are required. A side access guarding with additional testable Single Light Beam Safety Devices is also easy to set up, as the COMPACTplus-XSS/R Receiver also has an integrated type 2 test unit.

Furthermore the COMPACTplus-XSS/R Safety Light Curtain also has a 2-sensor Muting system, whereby a switchover between the shape scanning and the 2-sensor Muting is automatic. The user can therefore freely select which procedure they would prefer to set the safe paper roll feeding up with.

The shape scanning procedure with COMPACTplus-XSS/R Safety Light Curtains isn’t just possible with paper rolls – it is possible with all rectangular objects with closed contours, when transporting palettes in the intra-logistic area, for example. The Safety Light Curtain mounted at a tilt detects the palettes, provided they all have a pre-defined constant shape. If people enter the protective field, the Safety Light Curtain also detects this and switches off the dangerous movement.
