GreCon UPU 6000

Delamination Detection with the Ultrasonic Measuring System

The ultrasonic measuring system GreCon UPU 6000 detects inhomogeneities in panel-shaped materials, such as wood based panels, inline. Size and location of defective areas are recorded and visualised. Thus, defective panels can be identified and sorted out in time.
The measuring method supplies reliable results for both thick panels of up to 55 mm thickness and light panels of a density of < 550 kg/m³.
Depending on the required quality, different defect types, such as blows, that allow a graded quality sorting can be configured.

Benefits at a glance

  • Early detection and localisation of hidden defects
  • Prevention of blows by early recognition in the DC trend
  • Realisation of reserve capacities thanks to process trending
  • Higher output by increase in production speed
  • High availability and operational reliability of the system
  • High reliability of measured values because disturbing environmental influences are eliminated by automatic adjustment and an integrated dust accumulation control of the inspection channels

Measuring method

Ceramic transmitters are installed below the material flow. The ultrasonic signal generated by the transmitters penetrates the material and is received and evaluated by the receivers that are installed above the material flow. An attenuation of the received ultrasonic energy is registered as a deviation from the nominal value and indicates a possible weak point.
In order to protect the sound quality against disturbing influences, such as reflections, the wanted signal is protected by protection curtains.

In order to obtain good measuring results, the measuring conditions should be the same for all channels. The operator can check the function of the inspection channels and re-adjust, if necessary, by an electronic adjustment that can be conducted in panel gaps during the production


Software

Principally, all GreCon measuring systems base on the operating system Windows. The easy menu structure, which is almost the same for all measuring systems, makes an intuitive and user-friendly application possible. All relevant data of the products to be measured can be stored in the recipe administration. The measured data can be exported and processed in a customised way by a highly efficient reporting.

UPU 6000

for small installation depth

UPU 6000 ct

for easy maintenance

In the so-called ct-design, the frame construction is divided in the centre. The right and left measuring frames can be separately triggered and moved pneumatically. Thus, maintenance work can be conducted without production interruption. Even escape runs are possible, if required, to protect the channels against damage.

Construction of the system

The inspection channels required for measurement are mounted on a steel frame. The design of the system is individually adapted to the material to be measured and the local conditions. The frame can be equipped with a maximum of 32 inspection channels.

The closed frame concept protects all components, such as cable and air channels, transmitter electronics or compressed air lines, against surrounding environment. A hinged mechanism protects the channels against damage from big blisters.

Process optimisation

With this option, additional parameters, by means of which the operator can counteract the production of blisters and thus reduce the reject rate, are visualised. Instead of 5 colours that are standard, 250 colours are available for the representation of inhomogeneities of the measured panels.

For the improved resolution of measured values, a homogeneous calibration sample is automatically and mechanically placed between transmitter and receiver to be able to conduct the precise adjustment that is required for the resolution of 250 colours.

Furthermore, the system is equipped with an automatic dust accumulation control that is activated at predetermined intervals 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.

Extended working range
An extended range of transmitter and receiver components allows the measurement of special products, such as wood based panels of a thickness of up to 55 mm and a density of 550 kg/m³.

Software

Visualisation

The measured panels are graphically represented in 5 or 250 colours, depending on the configuration of the system. The colour balance provides information on the quality and homogeneity of the panels after pressing.

Quality indicator

A clear indication of the current panel quality is the quality indicator. All measured values of a panel are compressed and represented as a quality key on a scale, similar to a speedometer.

Long-term graphic

To represent the trend of the panel quality, the maximum value, the average value and the minimum value of a panel are shown in a long-term graphic. Influences on the production process, such as moisture and temperature fluctuations or changes in production speed, are understood.

DC long-term graphic (Deviation Control)

The DC value provides information on how homogeneous the panel was produced. The higher the DC value, the more inhomogeneous production, the higher the probability for blisters to occur. The DC value indicates technical problems with glueing, spreading, pressing, or similar upstream processes.
