Enhancing transparency, quality and utilisation by integrating quality assessment systems in a networked production.

The decisive economic factors in timber processing are product quality and production utilisation. Quality assessment systems integrated in the production process increase the automation level and, simultaneously, optimise utilisation.

Optimised cutting in networked production

KALLFASS has developed an interface concept that networks different software systems in a production line, thus enabling direct communication between individual processes. For example, the wane scanner installed in the sorting system determines board dimensions such as length, width, thickness and possibly quality, identifies flaws such as knotholes or wane and transmits these measurement results as cutting information directly to the KALLFASS trimmer saw. Trimmer saws normally only work with preconfigured grid lengths, but adding equipment to the system such as a servo-controlled, flexible zero stop upstream of the trimmer can cut out flaws with great precision while minimising the loss of wood.

As an alternative to scanning, the KALLFASS assessment chain conveyor can be used for a manual quality assessment of timber. Each board is individually accommodated and rotated through 180° before being deposited again on the conveyor. The operator can observe the timber from all sides and assign a characteristic.
