A circular conveying surface is supported on the rotatable support and is configured to convey articles supported thereon in a conveying direction when driven. One or more input conveyors and one or more output conveyors are positioned about the turntable conveyor. The conveying surface comprises a plurality of rollers that are rotationally driven and include a first set of rollers defining a first rotational surface and a second set of rollers defining a second rotational surface, where the conveying surface is configured to receive an article from a selected one of the inbound conveyors and to discharge the article to a selected one of the outbound conveyors. ## Claims ### Claim 1 A turntable conveyor for conveying articles, said conveyor comprising: a stationary frame; a rotatable support supported on said stationary frame; a first drive system operable to rotate said rotatable support about a vertical axis relative to said stationary frame between at least a first orientation and a second orientation; a conveying surface supported on said rotatable support, said conveying surface configured to convey the articles supported thereon in a conveying direction when driven; a second drive system operable to drive said conveying surface; and said conveying surface forming an inbound direction for receiving an article from a first conveyor when said rotatable support is rotated to the first orientation and forming an outbound direction for conveying the article supported thereon to a second conveyor when said rotatable support is rotated to the second orientation. ### Claim 2 (depends on 1) The turntable conveyor according to claim 1, wherein said first drive system is operable to rotate said rotatable support to a plurality of orientations to form at least one of a plurality of outbound directions or a plurality of inbound directions. ### Claim 3 (depends on 1) The turntable conveyor of claim 1, wherein said conveying surface comprises a plurality of driven rollers. ### Claim 4 (depends on 3) The turntable conveyor of claim 3, wherein the rollers are driven by a drive system supported on the turntable conveyor. ### Claim 5 (depends on 3) The turntable conveyor of claim 3, wherein the conveying surface comprises a circular conveying surface. ### Claim 6 (depends on 5) The turntable conveyor of claim 5, wherein said conveying surface comprises a first conveying surface portion and a second conveying surface portion, wherein the first conveying surface portion is formed of a plurality of rollers and the second conveying surface portion is formed of another plurality of rollers. ### Claim 7 (depends on 3) The turntable conveyor of claim 3, wherein said plurality of rollers includes first and second sets of rollers, said first set of rollers forming inbound rollers when said rotatable support is in said first orientation, and said first set of rollers forming outbound rollers when said rotatable support is in said second orientation. ### Claim 8 (depends on 7) The turntable conveyor of claim 7, wherein said first and second sets of rollers are driven in opposite directions by said second drive system wherein said second set of rollers form inbound rollers when said rotatable support is in said second orientation while said first set of rollers form said outbound direction. ### Claim 9 A conveyor system comprising: a turntable conveyor comprising; a stationary frame; a rotatable support supported on said stationary frame; a first drive system operable to rotate said rotatable support about a vertical axis relative to said stationary frame between at least a first orientation and a second orientation; a conveying surface supported on said rotatable support, said conveying surface configured to convey the articles supported thereon in a conveying direction when driven; a second drive system operable to drive said conveying surface; a plurality of conveyors adjacent to said turntable conveyor and comprising at least one inbound conveyor operable to convey articles to said conveying surface and at least one outbound conveyor operable to receive an article from said conveying surface; wherein said conveying surface forms an inbound direction for receiving an article from one of the at least one inbound conveyors when the conveying surface is rotated into alignment therewith, and wherein said conveying surface forms an outbound direction for conveying the article supported thereon to one of the at least one outbound conveyors when the conveying surface is rotated into alignment therewith. ### Claim 10 (depends on 9) The conveyor system of claim 9, wherein the conveying surface is circular and wherein the conveyors are disposed about a circumference of the conveying surface. ### Claim 11 (depends on 10) The conveyor system of claim 10, wherein the conveying surface comprises a plurality of rollers that are rotationally driven. ### Claim 12 (depends on 11) The conveyor system of claim 11, wherein the rollers are driven by a drive system supported on the turntable conveyor. ### Claim 13 (depends on 11) The conveyor system of claim 11, wherein the rollers comprise a first set of rollers defining a first rotational surface and a second set of rollers defining a second rotational surface, and wherein the first set of rollers are rotationally driven in an opposite rotational direction from the second set of rollers. ### Claim 14 (depends on 13) The conveyor system of claim 13, wherein in a first orientation of the conveying surface the at least one inbound conveyor is aligned with the first set of rollers for receiving an article from the inbound conveyor onto the first rotational surface, and wherein in a rotated second orientation of the conveying surface the first set of rollers is aligned with the at least one outbound conveyor for conveying the article from the first rotational surface to the outbound conveyor. ### Claim 15 (depends on 14) The conveyor system of claim 14, wherein the conveying surface is rotatable into a third orientation in which the at least one inbound conveyor is aligned with the second set of rollers for receiving another article from the inbound conveyor onto the second rotational surface, and wherein in a rotated fourth orientation of the conveying surface the second set of rollers is aligned with the at least one outbound conveyor for conveying the another article from the second rotations surface to the outbound conveyor. ### Claim 16 (depends on 13) The conveyor system of claim 13, wherein the at least one outbound conveyor comprises a plurality of outbound conveyors, and wherein in a first orientation of the conveying surface the at least one inbound conveyor is aligned with the first set of rollers for receiving an article from the inbound conveyor onto the first rotational surface, and wherein the conveying surface is rotatable such that the first set of rollers is alignable multiple ones of the outbound conveyors for selectively conveying the article to a selected one of the outbound conveyors. ### Claim 17 (depends on 16) The conveyor system of claim 16, wherein the at least one inbound conveyor comprises a plurality of inbound conveyors, and wherein the first set of rollers and the second set of rollers are selectively rotatably alignable with the inbound conveyors for receiving an article and are selectively rotatably alignable with the outbound conveyor for discharging the article to a selected one of the outbound conveyors. ### Claim 18 A conveyor system comprising: a turntable conveyor comprising; a stationary frame; a rotatable support supported on said stationary frame; a first drive system operable to rotate said rotatable support about a vertical axis; a circular conveying surface supported on said rotatable support, said conveying surface configured to convey the articles supported thereon in a conveying direction when driven; a plurality of input conveyors adjacent to the turntable conveyor and a plurality of outbound conveyors adjacent to the turntable; wherein the conveying surface comprises a plurality of rollers that are rotationally driven, and wherein the rollers comprise a first set of rollers defining a first rotational surface and a second set of rollers defining a second rotational surface, and wherein the conveying surface is configured to receive an article from a selected one of the inbound conveyors and to discharge the article to a selected one of the outbound conveyors. ### Claim 19 (depends on 18) The conveyor system of claim 18, wherein the first set of rollers are rotationally driven in an opposite rotational direction from the second set of rollers. ### Claim 20 (depends on 19) The conveyor system of claim 19, wherein the rollers are driven by a drive system supported on the turntable conveyor.
