GreCon DML 6000

Contactless inline thickness measurement with laser technology

 

The Thickness Gauge DML 6000 measures the material thickness of solid, soft and humid materials by contactless measuring using laser beams. The measured values can be taken to the very edge of the material. Depending on the requirements, measurements can be made at stationary points or traversing across the whole production width. Traverse measurement allows measurement of a maximum amount of material and clearly shows any linear deformation of the material.

 

Benefits at a glance

  • Rapid and early detection of quality fluctuations
  • Production control
  • No material has to be added for grinding
  • Indication of optimization potentials after production changes
  • Measuring data for production control

Measuring method

The Thickness Gauge DML measures the material thickness of solid, soft and humid materials by contactless measuring using laser beams.
In terms of the measuring principle, measurement against precision rollers is distinguished from difference measurement. When measuring against precision rollers, the material is scanned only from one side and a roller is on the opposite side corresponding to the zero line. The difference measurement determines the thickness of the material by scanning on both sides and calculating both values. The thickness is calculated by triangulation. A laser beam is sent to the material surface and observed by a camera provided beside it. If the distance to the board changes, the observation angle changes too and consequently also the position of the image in the sensor is different. The distance to the measured value can be calculated based on the position of the image. Individual measured values determine the material thickness by offsetting.
Afterwards, every measuring track is shown with the measured value in a graphic on a screen.
The production can be adapted to material saving.

Calibration

The DML 6000 is equipped with a calibration test function. Calibration is done below the production level and ensures consistent measuring accuracy.

SOFTWARE FUNCTIONS AND VISUALISATION

  • The visualization is the core of the software. The recorded measuring data is collected, registered and graphically processed. The easy menu structure which is adapted to all measuring systems makes an intuitive and user-friendly operation possible.

    The ergonomically designed software based on the Windows operating system allows an easy handling of the system by the operator. The recorded measured values are processed and displayed in a clearly structured way.

    Thanks to the visualisation software in modular design, the system can be adapted to your requirements so that the operation of the plant with different applications is possible. Furthermore the surface of the visualisation software can be compiled according to your needs.

  • The measuring data is issued graphically and numerically:

    • Alert if the tolerances are not observed 
    • Display of the position in which the tolerances are not observed 
    • Freely configurable display of numerical parameters as information on the production type or statistics
  • By integration of the raw panel scale, the weight and the average raw density are displayed in the visualisation software in addition to the measured thickness values.

    Oscillating operation
    Use in case of sanding lines. With this function, the measuring tracks are controlled automatically so that those tracks are active between which the panel moves. 

    Pack measurement
    Several panels are measured in a pack. The recorded measured pack values are evaluated per panel.
     

  • The system can be adapted optimally to the different requirements via recipes. The structure of the recipe management is very easy. The input of the panel-specific data enables the operator to start the measurement with only few mouse clicks. The start of a measurement and the necessary selection of a recipe make the integration of the measurement system into the process chain possible.

    All default values of a production type are saved in the recipe management. Besides the production parameters, as e.g. 

    • panel thickness
    • panel width
    • panel length
    • raw density
    • tolerances

    also all measuring-specific parameters are filed under the production type. When the production type is loaded again, all necessary parameters are available again.
     

    • Any panel data is stored in an SQL data base together with the recipe parameters and the measuring results.
    • Display of the position and the scope of the violated tolerances of historical panels.
    • Easy search function via date and time.
    • Export of panel data.
       
  • Individual time-relevant reports as e.g. the shift and month reports can be generated from the data base.

    The graphic presently shown on the screen can be printed out by pressing a button. Furthermore it is possible to print out a numerical report in case of a change of the production types or the shift.

    It is possible to generate different reports automatically and store or print them, as for example:

    • shift report
    • type report
    • graphic repor

    Furthermore it is possible to print out a screen shot of the history for statistical purposes. The data can also be exported from the history management in the standard file format XLS.
