Optical safety barrier enclosure for a print machine comprises optical transmitter and receiver each with a housing, one at least of which is mounted using an adapter that permits compensation of the tolerances of beam optics

摘要

Optical barrier enclosure for a print machine (1) has at least an optical transmitter and at least a receiver each with a housing and optical elements for creating optical paths (2.0-2.9) around the print machine. An adapter is provided for mounting of at least the transmitter or receiver housing, so that tolerances due to the optical elements are compensated and the optical axes of the optical elements that form the optical paths are optimally aligned.
