Provided is a veneer sorting control device including: a sorting condition setting unit 11 that sets sorting conditions for each of a plurality of kinds of defects so as to sort a veneer into a plurality of quality ranks; a defect detection unit 13 that detects the plurality of kinds of defects with respect to each of a plurality of pieces of veneer image data acquired from an image storage unit 100; a quality rank sorting unit 14 that sorts a plurality of the veneers into a plurality of quality ranks in correspondence with the sorting conditions which are set and defect detection states; a first totalization unit 15 that totalizes the number or a number ratio of the veneers in the plurality of quality ranks which are sorted; and a display control unit 17 that displays the totalization result on a screen. The number of the veneers sorted into the plurality of quality ranks can be confirmed by a simulation using the veneer image data stored in the image storage unit 100.

A log feeding apparatus for feeding a log to first and second cutting spindles is provided, in which a log is fed to a second receiving position when centering spindles have reached a second delivery position that is away from the second receiving position downstream in the direction of log transport by a distance equal to or greater than an assumed maximum diameter of the log. That is, a new log is transported to the second receiving position by placing sections when the log held between the centering spindles reaches a position that will avoid contact with the new log. As a result, the time can be reduced for transporting the log to the cutting spindles.
