Research and Development of Automatic Sawn Timber Defect Removal Line

Abstract

The article is devoted to the current problem of processing wood scraps with defects, which are products of the sawmill and wood processing industries. Modern wood trimming optimization lines using marking devices and laser scanners of the wood surface do not provide high accuracy in determining the location of defects and are quite expensive. The line for automatic removal of defects in lumber developed by the authors uses technical means of optical scanning of the surface of a wood blank and an ultrasonic detector that detects defects hidden in the body of the blank, which allows them to be cut with high accuracy.
