Abstract:
Embodiments provide methods, systems, and apparatuses for loading workpieces in a flow direction into the spaced apart lugs on a lugged conveyor with the workpieces oriented transverse to the flow direction. The lug loader includes an array of pairs of endless conveyors configured to convey workpieces toward a lugged conveyor. The first and second endless conveyors of each pair are spaced laterally apart across the flow direction and aligned substantially in the flow direction. The array can form a continuous or discontinuous transport surface. Some pairs of endless conveyors in the array may overlap one or more other pairs of endless conveyors in the array. At least one pair of endless conveyors in the array may include two or more endless conveyors that are independently driven at different speeds and/or in different directions to de-skew a workpiece.
Abstract:
A board unscrambler for sorting a plurality of boards comprises a frame having an entrance and an exit. The frame comprises a U-shaped accumulator near the entrance and an upwardly substantially longitudinal slope connecting the U-shaped accumulator portion to the exit. The board unscrambler further comprises a powered conveyor which substantially adopts the shape of the frame, comprising driving chains and a plurality of spaced apart catches mounted on the driving chains for mating with and displacing the boards along the frame from the U-shaped accumulator portion toward the exit. Accordingly, the board unscrambler features accumulation capability, thereby increasing efficiency and regulating performance.
Abstract:
A wood board feeding system for positioning in a parallel orientation longitudinal pieces of lumber. It comprises a feeding conveyor assembly configured to receive and convey the longitudinal pieces of lumber over a conveying area in a conveying direction. The feeding conveyor assembly comprises a first conveyor sub-assembly and a second conveyor sub-assembly, both comprising a conveyor for conveying the longitudinal pieces of lumber about one of their ends and a motor driving the conveyor at a conveying speed. The first conveyor and the second conveyor are disposed side-by-side with respect to the conveying direction, thereby the first conveyor sub-assembly and the second conveyor sub-assembly position a respective one of the two opposite ends of the longitudinal pieces of lumber.
Abstract:
Embodiments provide an electric lug loader system. An electric lug loader may include a shaft assembly rotatably mounted to a frame that extends across a flow path. The shaft assembly may have shafts arranged radially around, and parallel to, the rotational axis of the shaft assembly, clamp members arranged along each of the shafts, support members arranged radially around the rotational axis and across the flow path, and electric drives coupled to the shafts. Conveyors may be coupled with the frame and spaced apart across the flow path upstream and/or downstream of the shaft assembly. Additional drives may be coupled with the shaft assembly and the conveyors. A controller may be configured to synchronize the drives to engage successive workpieces between the clamp members and the support members and deposit the workpieces onto a lugged conveyor. Other embodiments provide related methods and systems.

Abstract:
An installation for separating and singulating non-uniform postal articles of the small parcel or packet type comprises a platform for temporarily storing a pile of loosely placed postal articles, a vision system adapted to form digital images of the pile of loose postal articles, which pile is static on the platform, a data-processing unit adapted to use these digital images to identify a postal article to be singulated, i.e. an article that has a pickup face that is not covered by any other postal article, the unit being suitable for delivering data indicating the three-dimensional position, the facing direction, and the dimensions of the pickup face, and a pneumatic pickup head of a robotized arm that is controlled on the basis of the data to lift up the postal article to be singulated via its pickup face, and to deposit the postal article on a deposition zone that is off the platform.
Abstract:
The present disclosure relates to a system and method of a sorter and a method for sorting wood pieces and for guiding them to a conveyor. This type of sorter comprises a lower frame, a receiving deck for wood pieces, and a feeder for detaching a wood piece from the receiving deck. Said feeder comprises a controller for supporting the wood piece during movement directed to it and transferring it substantially vertically from the receiving deck. In that case the control means is traversed by at least two bearers controlled by an actuator for producing the vertical movement of the wood piece. The bearers are arranged to project from an outer surface of the controller by an amount of projection that is adjustable during lifting. The feeder further comprises a measuring unit for detecting a wood piece of a given diameter (e.g., the largest or larger cross-sectional diameter) on the bearers and for controlling the projection of the bearers to a position corresponding to this given diameter.

Abstract:
A railroad tie stacker arrangement includes means for conveying ties to a tie accumulation deck to form a layer of parallel ties, means for conveying the layer of parallel ties onto a stack accumulation lift, and means for lowering the stack accumulation lift as each successive layer of ties is deposited onto the lift.
