CUTTING TOOL CONTROL BASED ON LOG POSITION

摘要

Embodiments of techniques and systems for control of cutting tools for logs on a conveyor are described herein. A preferred position may be determined for a log on a conveyor, such as, for example a chain conveyor. The preferred position may be determined based on a scan of the log prior to the log being placed on the conveyor. After the log is placed on the conveyor an initial portion of the log may be scanned by a second scan and the initial portion may be compared to a corresponding portion of the preferred position for the log. Differences may be determined between the scanned portion and the corresponding portion of the preferred position. One or more cutting tools may then be controlled, such as in position and/or orientation, to adjust for the determined differences. Other embodiments are also described and claimed.

主权项

1. A system comprising:
a conveyor configured to convey a log; a first scanner/optimizer configured to:
scan the log; anddetermine an optimized position for the log on the conveyor; one or more log positioning mechanisms configured to controllably rotate and/or position the log for placement of the log on the conveyor; and a second scanner/optimizer configured to:
scan a portion of the log after the log is placed on the conveyor;determine an actual position of the log on the conveyor;compare the scanned portion of the log to a corresponding portion of the optimized position for the log; andcontrol positions and/or orientations of one or more cutting tools or positioners positioned downstream of the second scanner/optimizer, the control being based at least in part on a result of the compare.
