Patent ID: 7849894

Claim:
A log rotation system comprising: an optimizer configured to identify an optimized rotational position of a log to be processed; a conveyor configured to convey the log in a first direction, the optimizer disposed proximal to the conveyor; an applicator operatively coupled to the conveyor, the applicator configured to apply a position indicator to a rearward portion of the log in a predetermined orientation to indicate a reference rotational position of the log; a log rotator disposed downstream of the optimizer, the log rotator configured to controllably rotate the log as the log is conveyed in the first direction; a primary rotational detector disposed upstream of the log rotator and downstream of the applicator, the primary rotational detector positioned to detect a current orientation of the position indicator during, after or during and after a first rotation of the log by the log rotator and while at least a portion of the log is within the log rotator; and a controller communicatively coupled to the primary rotational detector, the optimizer, and the log rotator, the controller configured to receive data from the optimizer and the primary rotational detector, control the first rotation of the log by the log rotator based at least on the optimized rotational position and the reference rotational position, the reference rotational position being set based on the predetermined orientation of the position indicator, determine, based at least on the current orientation of the position indicator detected by the primary rotational detector, a first rotational difference between a current rotational position of the log during or after the first rotation and the optimized rotational position identified by the optimizer, and initiate a corrective action to compensate for said first rotational difference.
