GreCon DMR 6000

Contact inline thickness measurement

The contact-type inline thickness measurement GreCon DMR 6000 measures the thickness of panel materials as e.g. MDF, OSB or chipboards and other materials as leather, caoutchouc, plastics or insulating paper. Available for different applications. With closed O-frame as standard use. With ct-measuring frame for an installation into endless production lines or very short product cycles.

BENEFITS AT A GLANCE

Increase of the material efficiency by reduction of the grinding allowance = reduction of the production costs

Makes a continuous quality control of the produced material possible

Connection of panels and mass per unit area scale possible to determine the raw density

Automatic calibration in smallest panel gaps to compensate the influences from the environment

Feedback of the measured value to adjust the press controluction control

Accessibility for maintenance also during production and calibration in the endless line by the ct-measuring frame.

DESIGN OF THE SYSTEM

The measuring tracks of the inline thickness measurement DMR 6000 are mounted to a stable measuring frame.The measuring tracks are distributed transversally to the production sense and can be shifted by simply loosening the screws manually. Measuring head types adapted to the applications are available depending on the material to be measured. Measuring heads with set point positioning make an almost complete measurement of the panel materials in production sense possible. The position of the measuring heads from the previous panel is maintained with this version of the measuring head. The necessary stroke of the measuring heads is hereby reduced and the measurement can start much faster. The life of the measuring heads is increased. The installation of the measuring frame is usually possible without extensive reconstruction efforts of the roller conveyor or the conveying unit. The control console is mounted directly onto the measuring frame and can also be installed in a distance to the system, if necessary. The ct-measuring frame is provided for an installation into the endless line; however it can also be installed at places where an access for maintenance purposes during production must be possible. The C-brackets can be moved out of the production line laterally in case of the ct-measuring frame. In case of tight spaces, the inline thickness measuring unit DMR 6000 can also be built in with the early blow detection UPU 6000.

MEASURING METHOD

The measured values are recorded by contact. Different measurement set-ups are available:

Differential measuring procedure with to measuring heads which are arranged opposite each other:

  • The measured material is scanned from both sides.
    The two measured values are offset against each other.
  • Thus, vibrations or any unevenness of the panels do not influence the measurement result.
  • The automatic calibration makes a consistent repeatability possible.
  • This measurement is reasonable in case of rough surfaces if the vertical position of the measured material varies or if the measured material is bent.

Differential measurement procedure with a measuring head and a stationary measuring roll as reference plane:

  • The measured material is scanned from one side. A stationary measuring roll on the other side is used as reference plane.
  • The measurement is appropriate for very thin materials which can be led in a smooth manner

SOFTWARE FUNCTIONS AND VISUALISATION

  • General

    The visualisation 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.

  • Measured Data

    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.
  • Special Function of Different System

    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 the 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.

  • Recipe Management

    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.

  • Database
    • 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.
    •  
  • Report Function

    • 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 report

      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.
