Conveyor system with multiple robot singulators and buffering conveyor
A conveyor system includes a first robot singulator, a second robot singulator, and a picking area from which parcels of a bulk flow of parcels can be engaged and transferred by the first robot singulator or the second robot singulator. The conveyor system further includes a first place conveyor positioned downstream of the picking area and configured to receive parcels transferred by the first robot singulator. The conveyor system further includes a second place conveyor positioned downstream of the picking area and the first place conveyor, the second place conveyor configured to receive parcels transferred by the second robot singulator and to receive parcels from the first place conveyor. A buffering conveyor is positioned between the first place conveyor and the second place conveyor for regulating a rate at which parcels offloaded by the first place conveyor are transferred to the second place conveyor.

a buffering conveyor positioned between the first place conveyor and the second place conveyor for regulating a rate at which parcels offloaded by the first place conveyor are transferred to the second place conveyor; and
a vision and control subsystem operably connected to the first robot singulator, the second robot singulator, and the buffering conveyor, the vision and control subsystem including
a first camera for acquiring one or more images of the picking area and any parcels located in the picking area, and
a controller including a processor for executing instructions stored in a memory component to (i) receive and process image data corresponding to an initial image of the picking area acquired by the first camera, (ii) selectively communicate instructions to the first robot singulator which cause the first robot singulator to engage and transfer parcels of the bulk flow of parcels positioned in the picking area to the first place conveyor, (iii) selectively communicate instructions to the second robot singulator which cause the second robot singulator to engage and transfer parcels positioned in the picking area to the second place conveyor, and (iv) selectively communicate instructions to the buffering conveyor which cause the buffering conveyor to index and transfer parcels from the first place conveyor to the second place conveyor.

4. The conveyor system according to claim 3 , wherein the first picking area is aligned with the first place conveyor, and wherein the second picking area is aligned with the second place conveyor.
5. The conveyor system according to claim 3 , wherein the first picking area is defined by a first section of a chute, and the second picking area is defined by a second section of the chute.
6. The conveyor system according to claim 1 , wherein parcels are delivered to the first robot singulator and the second robot singulator in a first direction, and wherein the first place conveyor and the second place conveyor receive and transfer parcels away from the first robot singulator and the second robot singulator in a second direction, which is substantially perpendicular to the first direction.
7. The conveyor system according to claim 1 , wherein the buffering conveyor comprises multiple buffering conveyors, with each of the multiple buffering conveyors being independently controlled by the vision and control subsystem to control movement of parcels from the first place conveyor to the second place conveyor.
8. The conveyor system according to claim 1 , and further comprising an additional conveying module incorporated into the second place conveyor which is configured both to convey parcels along a longitudinal axis of the second place conveyor and to selectively convey parcels in a transverse direction relative to the longitudinal axis.
9. A conveyor system, comprising:
a first robot singulator;
a second robot singulator;
a picking area, including a first picking area from which parcels of a bulk flow of parcels can be engaged and transferred by the first robot singulator, and a second picking area from which parcels of the bulk flow of parcels can be engaged and transferred by the second robot singulator;
a first place conveyor positioned downstream of the picking area and configured to receive parcels transferred by the first robot singulator from the first picking area;
a second place conveyor positioned downstream of the picking area and the first place conveyor, the second place conveyor configured to receive parcels transferred by the second robot singulator from the second picking area, and further configured to receive parcels from the first place conveyor; and
a buffering conveyor positioned between the first place conveyor and the second place conveyor for regulating a rate at which parcels offloaded by the first place conveyor are transferred to the second place conveyor.
10. The conveyor system according to claim 9 , and further comprising:
a vision and control subsystem operably connected to the first robot singulator, the second robot singulator, and the buffering conveyor, the vision and control subsystem including
a first camera for acquiring one or more images of the picking area and any parcels located in the picking area, and
a controller including a processor for executing instructions stored in a memory component to (i) receive and process image data corresponding to an initial image of the picking area acquired by the first camera, (ii) selectively communicate instructions to the first robot singulator which cause the first robot singulator to engage and transfer parcels of the bulk flow of parcels positioned in the first picking area to the first place conveyor, (iii) selectively communicate instructions to the second robot singulator which cause the second robot singulator to engage and transfer parcels positioned in the second picking area to the second place conveyor, and (iv) selectively communicate instructions to the buffering conveyor which cause the buffering conveyor to index and transfer parcels from the first place conveyor to the second place conveyor.
