Determination of log stability

摘要

Embodiments of techniques and systems for log stability determination are described. A log position optimizer may be configured to identify one or more rest positions for a log to be conveyed on a sharp chain. The rest positions may be identified based on identification of contact points where the sharp chain may contact the log that have no intervening contact points that prevent stable contact between the log and the sharp chain. A preferred rest position may be selected out of the identified rest positions. The preferred rest position may be selected based on determination of which contact points are stable or unstable. This determination may be made for each contact point in a cross-sectional plane of the log. The log position optimizer may then control a log positioning mechanism to position the log in the selected rest position. Other embodiments are also described and claimed.

主权项

1. A log handling system comprising:
one or more log positioning mechanisms configured to controllably rotate and/or position the log for placement onto a conveyor; and an optimizer configured to
identify, based on a scan of the log, a plurality of potential rest positions for the log on the conveyor, wherein each of the potential rest positions is at least partially defined by a corresponding pair of contact points along the log, and each of the contact points represents a potential point of contact with the conveyor;determine a predicted stability of the log on the conveyor in one or more of the potential rest positions,select a preferred rest position from among the one or more potential rest positions based at least in part on the predicted stability of the log on the conveyor in the preferred rest position, andcontrol the one or more log positioning mechanisms to position the log in the preferred rest position.
