Abstract:
1. A lug loader for loading workpieces in a flow direction into the spaced apart lugs on a lugged conveyor wherein the workpieces are transversely oriented relative to the flow direction, the lug loader comprising: an array of pairs of endless conveyors wherein each pair of endless conveyors in said array include first and second endless conveyors which are spaced laterally apart across said flow direction and each are substantially aligned in said flow direction, and wherein said array forms a continuous upper surface in said flow direction for supporting a workpiece translating downstream in said flow direction, said each pair of endless conveyors in said array overlapping adjacent pairs of endless conveyors in said array in said flow direction, wherein at least one of said each pair of endless conveyors in said array include independently actuable first and second drives independently driving corresponding said first and second endless conveyors respectively, wherein, when the workpiece is skewed from its transverse orientation, said first or second drive corresponding to said at least one of said each pair of endless conveyors advances the upstream-most end of the workpiece relative to its downstream-most end to correct the workpiece to an un-skewed position oriented transversely to the flow direction.
