LUMBER LOADING SYSTEM AND METHOD FOR SIMULTANEOUS LOADING AND LONGITUDINAL DISPLACEMENT OF SUCCESSIVE LUMBER PIECES USING SAME

摘要

A lumber loading system for transferring lumber pieces. The lumber loading system comprises a driving shaft rotating about a longitudinal axis; at least one lumber piece grasping assembly operatively connected to the driving shaft and rotating about the longitudinal axis; and a longitudinal positioning system connected to the at least one lumber piece grasping assembly. The at least one lumber piece grasping assembly is displaceable along the longitudinal axis and is operative to initially grasp a section of a corresponding lumber piece extending longitudinally substantially parallel to the longitudinal axis, temporarily maintain the section of the lumber piece and subsequently release the lumber piece. The longitudinal positioning system moves each one of the at least one lumber piece grasping assembly independently along the longitudinal axis, during rotation thereof about the longitudinal axis. A method for simultaneous loading and longitudinal displacement of successive lumber pieces is also provided.
