<p>A board edging infeed optimization system is described. The infeed system is equipped with a conveyor which transversely advances the board, a conventional optical scanning station, and a computer which calculates a longitudinal reference datum line and a preferred edging path for the board and places movable positioning pegs at a predetermined distance away from the preferred edging path. A novel mechanism is used to seize and transport the board further along the path by the predetermined distance so that the board's longitudinal reference datum line is placed colinear with the preferred infeed line into the edging device. The novel mechanism is characterized by the use of rotatable eccentric arm which sequentially advance and retract movable clamping jaws. After the board is placed along its preferred infeed line, grip rollers can longitudinally feed it into the edging device. If required, friction shoes may be installed directly above the general location of the positioning pegs to ensure that the advancing boards will sequentially come to rest in abutment with the positioning pegs and will not bounce or slide out of position. The eccentric arm assembly can optionally be provided with fluid operated telescopic arms which can be quickly adjusted to allow the infeed optimization system to selectively feed boards to a plurality of adjacent edging devices.</p> |
