Apparatus and methods for debarking logs

Abstract

Abstract LOG DEBARKING APPARATUS AND METHODS WHEREIN A LOG TO BE DEBARKED IS PRESENTED TO THE NIP BETWEEN TWO ROTATABLE LOG TURNING MEMBERS AND A TOOTHED DEBARKING MEMBER, THE LOG BEING ROTATED AND SIMULTANEOUSLY MOVED LENGTHWISE TO ENABLE THE DEBARKING MEMBER TO REMOVE BARK FROM THE ENTIRE PERIPHERY OF THE LOG. THE TURNING MEMBERS ARE YIELDABLY, BUT FORCIBLY, MAINTAINED IN ENGAGEMENT WITH THE LOG BY A FLUID PRESSURE CYLINDER, AND THE TURNING MEMBERS ARE CAPABLE OF RELATIVE MOVEMENT TOWARD AND AWAY FROM ONE ANOTHER TO ENABLE LOGS OF IRREGULAR CROSS SECTION TO BE ACCOMMODATED BETWEEN THE TURNING MEMBERS. THE SPEED OF ROTATION OF EACH TURNING MEMBER IS THE SAME WITH ROUND LOGS BUT IS AUTOMATICALLY VARIABLE TO ENABLE THE PERIPHERAL SPEED OF EACH TURNING MEMBER TO CORRESPOND TO THE PERIPHERAL SPEED OF THE LOG AT THE POINT WHERE THE LATTER ENGAGES THE TURNING MEMBERS TO AVOID SLIPPAGE WHEN DEBARKING LOGS OR IRREGULAR SHAPE AND ENSURE THAT BOTH TURNING MEMBERS ARE ALWAYS EXERTING AN EQUAL TORQUE TO ROTATE THE LOG. THE AXES OF ROTATION OF THE TURNING MEMBERS ARE INCLINED TO THE AXIS OF ROTATION OF THE LOG, AND THE AXES OF ROTATION OF THE TURNING MEMBERS ARE AUTOMATICALLY ADJUSTED ACCORDING TO THE DIAMETER OF THE LOG FOR VARYING THE SPEED AT WHICH A LOG IS MOVED LENGTHWISE THROUGH THE MACHINE.
