Estimating the term…
The invention relates to a method for the machine-reading of markings on/in transparent, especially pane-type, marking carriers, especially glass panes, according to which the marking carrier (2) is illuminated with UV light at least during the period of a machine-reading process of a marking, especially by means of a reading device (4), in order to increase the contrast between a marking (5) and the marking carrier (2). The invention also relates to a device for the machine-reading of markings in transparent, especially pane-type, marking carriers, especially glass panes, comprising at least one reading device (4) for markings arranged on/in a marking carrier, and at least one illumination device (4) is provided for increasing the contrast between a marking (5) and the surrounding transparent marking carrier (2) by illuminating the marking carrier (2) with UV light.
1-20. (canceled)
A method for machine-reading of markings on/in transparent, especially pane-type, marking carriers, especially glass panes wherein the markings are created from laser-produced micro cracks and/or metal particles/metal ions in the volume of the marking carrier and at least during the period of a machine-reading and recognition process, especially by means of a reading device, the contrast between the marking and the marking carrier is increased by illumination of the marking carrier with UV light.
An apparatus for machine-reading of marking in transparent, especially pane-type marking carriers, particularly glass panes wherein it has at least one reading The apparatus for markings arranged in/on a marking carrier and is provided with at least one illumination The apparatus in order to increase the contrast between a marking and the surrounding transparent marking carrier by means of UV light exposure.
The apparatus according to claim 15 wherein it comprises at least one roller conveyor table or one roller transfer path for transfer of pane-type marking carriers, especially glass panes, whereby reading and illumination The apparatus are arranged on the roller conveyor table/roller transfer path.
The apparatus according to claim 15 wherein several illumination and reading devices are provided for simultaneous reading of markings of several marking carriers.
The apparatus according to claim 15 wherein at least one illumination and reading device is are arranged between two rollers and/or at the end of a roller conveyor table/roller transfer path.
The apparatus according to claim 15 wherein it comprises an arrangement of several linear reading/illumination devices lying next to each other/in tandem, which in particular can be mounted between two rollers or at the end of a table/path, particularly whereby the arrangement is developed as a strip.
The apparatus according to claim 15 wherein a reading and illumination unit are developed as a structural element.
