Abstract:
A rotatable saw unit for optimized log breakdown of a workpiece fed from an infeed conveyor comprising:a saw unit immediately downstream of said infeed conveyor cooperating with said infeed conveyor for sawing said workpiece as said workpiece is translated by said infeed conveyor into said saw unit, said saw unit including at least one saw aligned for said sawing of said workpiece in at least one plane corresponding to said at least one saw and generally parallel to a longitudinal infeed axis of said infeed conveyor, said infeed conveyor for translating said workpiece in a downs direction along said longitudinal infeed axis, said workpiece lying on said infeed conveyor substantially parallel to said longitudinal infeed axis, at least one scanner positioned along said infeed conveyor for sensing orientation of said workpiece relative to said longitudinal infeed axis and for generating corresponding orientation data, an optimizing processor for processing said orientation data and for determining an optimized sawing orientation of said at least one plane relative to said longitudinal infeed axis, a saw unit positioner for selective rotating of said saw unit about a saw unit rotation axis so as to rotate said at least one saw into said optimized sawing orientation prior to said sawing of said workpiece for sawing of said workpiece in said optimized sawing orientation, wherein said saw unit rotation axis is co-axial with said longitudinal infeed axis.
