Your Benefit ■■ Quick and timely recognition of quality deviations ■■ Production control within precise tolerance limits ■■ No excess material required to be added for sanding = reduction of production costs (0.1 mm ~ 0.8 % material) ■■ Display of optimisation potentials after changes in the production (intentional or unintentional) ■■ Measurement data to regulate the press Why GreCon ■■ Customer-specific system design ■■ High innovative capacity: more than 10 % of the employees work in the R & D division ■■ Worldwide customer service network: more than 80 service technicians on duty worldwide...

Design and Construction of the System The innovative frame concept of the thickness gauge includes an optimised frame construction and allows stable measurements using carbon fibre components. An optimum distribution of horizontal forces by a concentric track arrangement was considered and contributes to the high precision. The closed frame protects all components, such as cable and air channels, measuring head electronics and compressed air supply, against damage from surrounding industrial environment. A modification of the conveyor is only necessary in individual cases. Easily accessible inspection...

Measuring Principle A consistent measuring accuracy of the system is ensured by an automatic calibration system. For contact measurement, high-precision rollers contact the material and convert thickness variations into vertical motion within the transducer. The measurement is achieved with an optical element inside the transducer heads. The measuring heads are installed in pairs, opposite each other, above and below the panel to ensure accurate measurements, even during bending or vertical movement of the panel. To protect the measuring heads against mechanical damage, they are equipped with...

Measuring System Analysis (MSA), Type-1 Study Set-Point Positioning GreCon checks the accuracy and repeating accuracy of a DMR 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 measuring heads will stay in their positions after the last measurement. This reduces the mechanical strain of both the panel edges and the measuring heads. The consumption of compressed air is also reduced. Even with compressed air failure, the heads will stay in their last position....

Software Functions ■■ Software The visualisation software of all GreCon measuring systems is based on Windows. The software of the DMR 6000 consists of the following program modules: ■■ Network Connection For the data transmission to higher-ranking process control systems, different network connections, such as OPC or ODBC, are available. Profibus and Profinet are available on demand. Visualisation of raw panel production Visualisation of sanding line ■■ Visualisation The core of the software package is the visualisation software. It records, stores and graphically represents all measured data....

Service GreCon measuring systems are equipped with GreCon online support SATELLITE. This provides safe, simple and fast remote support when there is trouble or to check the system. Each online support is logged and stored in the system‘s history. Optionally, we offer a check of measuring means, in which the standard deviation as well as the accuracy of measured values are determined. Calibration An automatic calibration system ensures consistent measuring accuracy for all measuring principles. The measuring heads are brought together and calibrated. For thickness measurement with ct-frame, calibration...

The DMR 6000 is used in the following 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. ■■ Carbon board ■■ Fibreboard ■■ Gypsum board ■■ Glass fibre board ■■ Rubber ■■ Wood based panels ■■ Insulating cardboard ■■ Plastic boards or endless plastic foils ■■ Solid wood ■■ Mineral fibre ■■ Wet fibreboard ■■ Leather ■■ Linoleum ■■ Pallet blocks ■■ Plexiglass ■■ Plywood ■■ Expanded metal ■■ Insulating...
