A sort bin for unloading sorted lumber pieces on a conveyor is disclosed. The sort bin comprises a compartment having first and second spaced-apart walls for containing the lumber pieces in a pile, an entry located at an upper portion of the compartment for introducing lumber pieces, and an exit located at a bottom portion, the conveyor being below the exit and spaced apart therefrom. The sort bin further comprises a support for supporting the pile of lumber pieces contained in the compartment. The support is movable along a course extending between an upper position adjacent to the entry and a lower position below the exit of the compartment; and has side members for preventing a spill of lumber pieces on the conveyor when the support is in its lower position. One of the side members is pivotable between a standard position and an unloading position. Mechanisms are provided to move the support between the upper and lower positions; and to pivot the pivotable side member between the standard position, where a bottom end portion of the pile is held, and the unloading position, where the lumber pieces of the pile are unloaded on the conveyor.
