A bin sorter for sorting lumber is provided. The bin sorter includes a plurality of bins disposed in a side-by-side configuration. Each bin includes a pair of spaced-apart walls defining a compartment therebetween for receiving lumber. Each compartment has a compartment inlet provided at a top end thereof, and a compartment outlet provided at a bottom end thereof. At least one of the plurality of bins has a support assembly for supporting one or more piles of lumber within the compartment. The support assembly includes a pair of support members having a support base vertically displaceable between the top and bottom ends of the compartment and a support arm connected to the support base and extending within the compartment towards the other support arm. Each support arm is adapted to support a respective pile of lumber or cooperate with one another to support a single pile of lumber.

In a method for separating a sawn timber pack obtained from one trunk into main yield and side cuttings using a separating conveyor, the sawn timber pack is conveyed in a longitudinal direction via an underside transport device of the separating conveyor. While the single- or multi-piece main yield is supported by the transport device, one or more side boards are separated transverse to the conveying direction using gravitational force and/or external forces, whereby lateral retaining elements are briefly opened for release. In order to be able to process trunks with as large a diameter range as possible, the side boards located on opposing sides of the sawn wood pack are separated in two successive separating stages, whereby the lateral retaining elements of the separating conveyor are opened on one side on a respective release side in the successive separating stages.

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.

The present disclosure provides systems, methods and assemblies comprising one or more tapered feed rolls. Tapered feed rolls may be used to change the rate and direction of workpiece travel along a processing line while retaining the workpieces in sequential order. Routing workpiece flow with tapered feed rolls may allow the workpieces to be tracked along one or more processing lines, and may reduce the operational space required for workpiece processing.

An apparatus for separating a sawn timber package cut from a log into main and side products during longitudinal transport thereof, having at least one separating device positioned such that, during a feed motion of the sawn timber package, it engages in a sawing gap between single- or multi-cut main product and side product and deflects the side product in a direction leading away from the main product. Two rotatably mounted conical rollers form the separating device, each having a circumferential separating edge formed by two surfaces of revolution enclosing an acute angle, and the two conical rollers are arranged on both sides of the sawn timber package and oriented such that they engage laterally into the sawing gap with respective separating edges and roll on the main product with their first surface of revolution, while deflecting the side product from the main product with their second surface of revolution.

A lumber cutting and delivery system for use in assembling trusses on a truss table includes a saw for cutting a piece of material into pieces of a truss. A trunk conveyor system receives the pieces cut from the saw. The trunk conveyor system has a first conveying element to transport the pieces over a distance in a travel direction and an ejector for discharging the pieces from the first conveying element in a first discharge direction. A branch conveyor system is configured to receive the pieces discharged from the trunk conveyor system in the first discharge direction. The branch conveyor system has a main conveying element to transport the pieces.
