Inline Thickness Measurement for Quality Assurance with Laser Technology

DML 6000

Your Benefit

  • Fast and early detection of fluctuations in quality
  • Production control within restricted tolerance limits
  • No material required to be added for sanding = reduction of production costs (0.1 mm ~ 0.8 % material)
  • Display of optimisation potentials after changes in production (desired or undesired)
  • Measuring data to regulate the press

ct-Frame

To achieve continuous system availability, the DML 6000 can be equipped with a ct-frame. Maintenance, diagnostics and repairs can be conducted during the running production. Additionally, the mobile construction of the system allows an escape run in case of big blisters and thus prevents the measuring system from being damaged.

Measuring System Analysis (MSA), Type-1 Study

GreCon checks the accuracy and repeating accuracy of a DML 6000 during the internal system check after the system is built. The measurement capability of the system is a calculation of statistical quality parameters based on the measured results. The operator can repeat this procedure at any time after installation and start-up of the measuring system thus providing a reproducible system check.

User-Friendly, Simple, Robust and Accurate

High availability, operational reliability and, above all, consistent measuring quality are ensured by the calibration with integrated self-diagnosis system and the construction of the system. This leads to high confidence in the system and acceptance by the operator. The MSA ensures that the displayed information constitutes a reliable basis for the monitoring and optimisation of the production process.

Edge Sanding Monitoring

The edge sanding monitoring separately evaluates the beginning and the end of a sanded panel according to recipe-specific values. The results are transferred to the PLC by OPC via the data table.

Combination with other Measuring Systems

Since the thickness gauge is a modular system, it is possible to change the measuring requirements at any time. The system can be combined with the Ultrasonic Measuring System UPU 6000 and a Board Scale to provide a quality assurance station. This combination is primarily used after continuous presses.

Applications

  • After the Press

In the wood based industry, thickness gauges are combined with GreCon Ultrasonic Measuring Systems UPU 6000 and Board Scales to a quality assurance station. Data is recorded and evaluated by one central visualisation computer.

  • Sanding Line

A combination of up to three thickness gauges is used for final quality control in the sanding line. For example: a 1-track thickness gauge is installed before the calibration sander, a 2-track system after the calibration sander and a 3-, 5- or 7-track system after the finishing sander. Besides quality control, the measured data can be used to adjust the sanders to the desired thickness values.
