The production of wood-based panels is a complex process where even the smallest details can determine whether a product is rejected or moves on for further processing. Edge quality, in particular, is a critical aspect of the overall product. Faulty edges not only affect the appearance but can also lead to future issues, such as moisture seeping through cracks, compromising the stability of the component. This type of defect can be costly, often resulting in expensive replacements.
The fully automatic edge inspection system GreCon EDGEINSPECT not only identifies these defective edges at an early stage, but above all distinguishes between real break-outs, quality deviations within the tolerance range or deceptive elevations such as dust or glue residues. Now, leaving the selection and assessment of the quality of wood-based materials has got so easy with EDGEINSPECT. One can easily rely on meaningful values as well as more than 40 years of industry experience from the measurement technology specialist Fagus-GreCon!
Reliable detection by means of laser
Classically at home in the edge banding of a furniture or door manufacturer, GreCon EDGEINSPECT consists of up to two combinable laser compact sensors.
1) EDGEINSPECT uses a laser compact sensor to look from the underside of the panel over the round edge to the make-up. Accordingly, a visible edge is defined by the customer.
2) EDGEINSPECT looks at the component with two laser compact sensors and thus detects two edges – i.e. also potential defects on the bottom and top side.
In this way, GreCon EDGEINSPECT reliably detects the most diverse types of defects such as edge chipping, missing or too short edges as well as dents. EDGEINSPECT also reliably monitors the adherence to the gap dimensions between the edge banding and the board as well as the detection of open glue joints.
Three dimensions for the perfect all-round view
Comparable systems on the market often rely on interpreting camera-based intensity images to assess edge quality. However, this approach presents challenges in practice, particularly with color-textured surfaces, as these systems must distinguish between intentional design variations—such as those found in different kitchen styles—and actual defects. Achieving this distinction requires manual input and training by employees, and constant adjustments must be made whenever production processes change.
GreCon laser compact sensors, on the other hand, measure the complete three-dimensional geometry of a component in the ongoing production process – they do not interpret images, but measure the wooden panel for elevations, depths as well as width and thus assess potential sources of error on the basis of precise environmental data.
This means:
Even in competition with comparable, laser-based measuring methods, GreCon EDGEINSPECT is more than a nose ahead of other systems – thanks to its intelligent exposure control.
It provides you with reliable edge inspection without the need for manual adjustments – even with constantly changing surfaces with different colours and brightness differences. Thanks to its intelligent exposure adjustment, even black and white checkerboard patterns do not pose any major challenges for GreCon EDGEINSPECT when it comes to defect detection – a real revolution for your production process!
