The UPU 6000 has integrated blow detection for final quality control and sorting of the measured panels. If blows occur, their size and location is clearly represented. The defective panels are marked, and a signal is given to allow them to be identified for rejection. Different blow definitions allow a graded quality sorting.
With the quality of the measuring results dependent on consistent conditions during measurement, the GreCon Ultrasonic Measuring System is equipped with an adjustment function. The inspection channels can be checked and re-adjusted. The electronic adjustment can be conducted in panel gaps during the production.
Get the maximum out of your production with the process optimisation option. With this option, the resolution of the measured data is increased so that influences affecting the production process can be detected even faster.
The improved resolution of measured values requires a special method to adjust the inspection channels: A defined reference sample, which guarantees an exact adjustment is required for the resolution of 250 colours and placed between transmitter and receiver.
The system is equipped with an automatic dust accumulation control which is activated at predetermined intervals after calibration. This is done in the gap between two panels and does not disturb the measuring process. If the values of an inspection channel strongly deviate from the reference value, a warning signal is sent to the operator. If the degree of dust accumulation exceeds the limiting value, the next maintenance interval is indicated to the operator.
Using the high-resolution trend analysis calculation from the measured values, the plant operator is able to prevent the production of blister or blown panels. This way, the production of rejects can be avoided and the production speed increased. The signal detected by the ultrasonic receivers is influenced by changes in important process parameters, such as press factors, density or material moisture. These process parameters directly influence the quality of a panel.
