Abstract
A device for depositing a wipe-proof and rub-proof marking or code marking, in particular a two-dimensional matrix or line coding onto glass receptacles such as glass ampoules, glass bottles, vials and likewise, comprises a transport means having a drive, with one or more accommodating devices for objects to be inscribed, a laser system arranged at a distance to the transport means with a laser source for producing a laser light beam of a wavelength <380 nm, said laser light beam in operation being directed onto the transport path and defining an impingement point in the region of at least one accommodating means moved along the transport path, means in order to deflect the laser light beam in a first and in a second direction continuously or in certain incremental intervals, and at least one control unit comprising a memory unit and a microprocessor which is in connection with the laser system and the deflection means, for controlling at least the deflection system and the laser system. The device further comprises a transport means designed for the transport of glass receptacles to be marked, along a transport path, a means for detecting or determining at least the position of at…
