Abstract

A plank positioning mechanism is adapted to move planks traveling in a
traveling
direction on a conveyor. The plank positioning mechanism comprises a conveying

means traveling parallel to the conveyor; and a plurality of paddle assemblies

mounted equidistant to the conveying means perpendicular to the traveling
direction. The paddle assemblies comprise a movable part; and a motor adapted
to drive the movable part perpendicular to the conveyor, Thereby, the movable
part
is adapted to thrust the plank perpendicular to its traveling direction as the
paddle
assembly travel parallel to the board.

Abstract

A pivotable log saw is movable between an operating position and a maintenance position. The saw includes: a housing; a turntable pivotably mounted to the housing to rotate around an axis; a saw arm pivotably mounted to the turntable to rotate around another axis; an arm-driving motor mounted to the turntable, the arm-driving motor being connected to the saw arm and controlling slope of the saw arm; a blade-driving motor mounted to the saw arm, a saw blade mounted to the saw arm, and connection between the blade-driving motor and the saw blade wherethrough the blade-driving motor drives rotation of the saw blade; and a locking mechanism adapted, in a locked position, to lock the turntable in the operating position, and, in an unlocked position, allows the turntable to rotate in a maintenance position.

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. The controller also has at least one output for sending independent control signals to the motorized blocking fingers respectively, in response to the detecting signals, for moving the respective blocking fingers for which a lumber presence is detected from a blocking to an unblocking position, and otherwise keeping the respective motorized blocking fingers in their blocking position.
