Abstract: A lumber transfer system for transferring pieces of lumber comprising a feeding conveyor having a conveying surface for receiving the pieces of lumber; a plurality of grasping assemblies spaced apart transversely along the conveying surface, each one of the grasping assemblies comprising a grasping finger able to be positioned independently for either grasping a piece of lumber located upstream from the grasping assembly and moving it, or preventing it from grasping a piece of lumber; a detection system for detecting a presence of a piece of lumber and producing signals; and a controller controlling the grasping assemblies for the grasping fingers to be positioned independently. The lumber transfer system is therefore able to have only grasping fingers responsible to grasp the piece of lumber to be in a grasping position.

Abstract: A lumber transfer system and a method for individually transferring lumbers from a feeding conveyor to an outfeed conveyor. Detectors are used for monitoring a lumber presence along a corridor on a longitudinal conveying surface. Motorized blocking fingers located about the corridor and transversally spaced along the conveying surface are provided and are configured for moving between blocking and unblocking positions. A controller is also provided, the controller having at least one input for receiving detecting signals from the detectors respectively, the detecting signals of the detectors being respectively associated to the motorized blocking fingers.
