Definitions
- the invention relates to an application and a method for checking documents.
- Test methods are not used in high-speed processing machines.
- a test for example of banknotes with a hologram authenticity feature, is within one
- diffraction-optically effective layers consist of a metallized layer. This metallization layer is electrically conductive. The electrical conductivity changes according to the layer thickness.
- the diffraction-optically effective layer has a discontinuous metallization layer and / or partially metallic layers and / or zones of metallic layers in different planes.
- Various measuring methods are known which demonstrate electrical conductivity. In practice, the contactless, capacitive measuring method has proven to be practical.
- the capacitive coupling between the transmitter and receiver and the transmission of energy between the transmitter and receiver are carried out by Bridging an electromagnetic field exploited by electrically conductive safety materials.
- Subsequent evaluation electronics compare the signal image of the test object with the corresponding reference signals. The comparison provides a classifying signal for further processing. Accordingly, for example, a document recognized as a false certificate could be sorted out by stopping the test device.
- the signal pattern depends on the structure of the metallized layer of the diffraction-optical layer. If the diffraction-optically active layers have a discontinuous metallization layer, then several segments of the metallization layer have different electrical conductivities. Practice has shown that these different conductivities affect the signal pattern.
- additional authenticity features into demetalized segments within discontinuous metallization layers and / or partially metallic layers and / or between zones of metallic layers in different levels, these features and the electrical conductivity can be checked at the same time.
- an authenticity signal of another sensor for authenticity determination is logically linked to the sensor for measuring the electrical conductivity.
- At the output of the evaluation electronics there is a signal that classifies the diffraction-optically effective layer for further processing.
- This additional authenticity feature has fluorescent, phosphorescent or light absorbing properties or differs from its surroundings by different magnetic properties. Accordingly, an optical or magnetic sensor is used.
- a sensor carrier is preferably used to reduce detection and measurement errors used. This sensor carrier takes all sensors for the detection of authenticity features
- the sensor carrier is compact
- Test facility is located inside processing machines, so none
- Fig. 1 shows a schematic section through a processing machine
- 2a shows a schematic section through a hologram with demetalized segments
- FIG. 3 a schematic section through a hologram with discontinuous
- FIG. 4a shows a schematic section through a hologram with a UV authenticity feature Fig. 4b voltage-time diagram of the evaluation signal of the electrical
- the test method according to the invention provides that the corresponding sensors are installed in banknote counting machines at suitable positions.
- the sensors for detecting the electrical conductivity are designed such that the entire banknote path width is monitored, so that the sensor can check the banknotes in a position-neutral manner.
- Optical or mechanical sensors detect the presence of a banknote and supply a reference signal for the time control of the test device 4.
- the sensors for checking the authenticity of the hologram are also activated thereby.
- the position of the hologram on the banknote can be determined by recording the entire time window from the beginning of the banknote to the end thereof. 1 shows how the test device 4 is arranged in the transport path of the banknote.
- the banknote counting machine includes a feed wheel 1, transport wheels 2, a banknote guiding device 3 and a checking device 4.
- FIG. 2a shows a schematic section through a hologram with a carrier layer 11 and a partially metallic layer 12.
- the partially metallic layer 12 contains several demetallized segments 13.
- the associated evaluation signal is shown in FIG. 2b in a voltage-time diagram.
- 3 a shows a schematic section through a hologram with a carrier layer 11 and a discontinuous metallization layer 14.
- the discontinuous Metallization layer 14 contains segments 15, 16, 17, 18, 19 with different electrical conductivity.
- 3b shows the associated evaluation signal in a voltage-time diagram.
- FIG. 4a shows a schematic section through a hologram with a carrier layer 11 and a discontinuous metallization layer 20.
- the discontinuous metallization layer 20 contains demetallized segments 21 and additional authenticity checking features. These authenticity features are fluorescent colors 22, which are excited during the test by means of UV light and detected by means of photosensors.
- the additional authenticity check features are preferably located within the demetallized segments 21.
- FIG. 4b the associated evaluation signal of the capacitively operating sensor that checks the electrical conductivity is shown in a voltage-time diagram.
- 4c shows the course of the evaluation signal of the photosensor in a voltage-time diagram.
