Patent ID: 7870879

Claim:
An automated saw system for cutting a crooked piece of lumber having a width, the saw system comprising: a saw support; a saw mounted on the support for cutting a piece of lumber at a cutting location; a cutting stroke piston operatively connected to the saw for movement of the saw in a cutting stroke to cut the piece of lumber; a conveyor located relative to the saw for feeding the piece of lumber to the saw along a conveyor axis, the saw and the conveyor being arranged so that the piece of lumber fed to the saw is cut through the piece's width; a sensor mounted on the saw system relative to the saw for detecting a deviation amount by which the piece of lumber deviates from an idealized straight piece of lumber; a controller in communication with the sensor and one of the saw and the conveyor, the controller adjusting the position of one of the saw and the piece of lumber on the conveyor in response to the detected deviation amount so that the piece of lumber is cut through the piece's width to correspond to a cut of the idealized straight piece of lumber; and an adjuster operatively connected to the controller and the saw for varying a position of the saw relative to the conveyor in an adjustment direction along an axis substantially perpendicular to the conveyor axis and extending vertically in a plane substantially perpendicular to a horizontal plane including the conveyor axis, the varying of position by the adjuster being independent of the cutting stroke movement of the saw by the cutting stroke piston.
