Griffin Lumber, Cordele, Ga., is upgrading its Lineal High Grader (LHG) with Deep Learning technology to detect knots and pith.

The LHG was installed at Griffin in 2007, and since then it has been providing accurate grades and facilitating the production of MSR/MEL products. The upgrade is scheduled to be completed in the second quarter of 2020.

As part of the modernization, the hardware will be updated to ensure continued performance and reliability of the LHG for years to come. A scan tunnel will shield the sensors from debris, new LED light bars utilize higher intensity light for more accurate defect detection, ethernet-based laser profile and vision sensors provide faster data transfer for improved defect detection, and new GPU computers afford the highest speed decision processing and Deep Learning functionality.

The WinTally sorter management system will also be upgraded to the latest software platform. WinTally works hand-in-hand with the LHG to manage the products the mill is producing.
