UPU 4000 Bond Analyzer and Blow Detector

 

The GreCon Ultrasonic Measuring System is the optimum measuring system to produce high quality wood based panels at optimized cost. At the same time, blisters can be avoided thanks to the integrated blow detection system.

Using the trend calculation from the measured values, the plant operator is able to prevent the production of blister panels. This way, the production of rejects can be avoided. The signal detected by the ultrasonic receivers is influenced by changes in important process parameters, such as press settings, density or material moisture. These process parameters directly influence the quality of a panel. The degree of glue cure is a measure of ultrasound absorption. The higher the degree of glue cure, the lower the absorption of the ultrasound by the panel.

Besides the parameters to optimize the production process, the UPU presents an integrated blow detection for final quality control and classification 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.

Principle

Ultrasonic transmitters and receivers scan passing panels, and a central processor provides on-line monitoring, statistical analysis and warning alarms for production defects.

The transmitter generates ultrasonic pulses, sending them through the panel from below. When a blow appears in the panel, the ultrasonic waves are weakened due to the reflection of the signal occurring inside the panel. This considerable energy reduction is immediately recognized as a quality defect.

The Visualization Computer Display data, combined with other production data, can reveal additional optimization potential.

In a production run the measured data can be easily traced or analyzed over time. The visualization computer will produce a similar graphic display for the operator. This data, combined with other production data, can reveal additional optimization potential.

CT-Frame Option
The Visualization Computer Display data, combined with other production data, can reveal additional optimization potential.

New CT-Frame provides continuous system availability. One side of the CT-Frame moves sideways out of the production run to provide access for maintenance and calibration while the other side continues to measure panel board quality. Additionally the CT-Frame provides for an emergency escape run in case of big blisters in the panel board thus preventing damage to the measuring system.
