ABSTRACT:
A method and an apparatus for automatically detecting the approximate percentage of humidity in predetermined types of lumber cut to specific lengths. A conveyor is provided for conveying individual pieces of cut lumber to a weighing station which consists of platforms on which individual pieces of lumber are conveyed. One or more weighing cells are associated with the platforms for detecting the weight of the piece of lumber thereon. A control circuit is connected to the weighing cell and also to sensors which detect a predetermined length of the lumber pieces and the cross-sectional dimension thereof, and receives information signals therefrom to identify and classify the individual lumber pieces in accordance with one or more reference signals related to selected humidity content weight(s) of the lumber pieces. The apparatus compares the apparent density with selectable density(ies) used as criterium for sorting.
