Abstract

Disclosed are various embodiments for a singulator that has a port for diverting items. An item is received on at least one conveyor segment of a singulator. The item is transported using the at least one conveyor segment to a side wall of the singulator. The item is transported using the at least one conveyor segment through a port in the side wall of the singulator.

Claims

1. A system, comprising:

a singulator that comprises;

a side wall having a slot that forms an opening in the side wall, the slot having a horizontal length that is greater than a vertical height associated with the slot;

a guard that covers a portion of the slot in the side wall and restricts access to the singulator through the slot; and

at least one conveyor segment configured to;

transport a first packaged product along at least a portion of the at least one conveyor segment using a plurality of driven rollers having a plurality of axes that are skewed relative to the side wall;

transport the first packaged product along the side wall past the slot to an end of the at least one conveyor segment;

transport a second packaged product along at least a portion of the at least one conveyor segment using the plurality of driven rollers; and

transport the second packaged product through the slot in the side wall.

2. The system of claim 1, wherein the system further comprises a container that receives the second packaged product after the second packaged product is transported through the slot in the side wall.

3. The system of claim 1, wherein the guard comprises a material that is transparent to light.

4. The system of claim 1, wherein:

the side wall further comprises an additional slot that forms an additional opening in the side wall; and

the conveyor is configured to transport a third item through the additional slot.

5. The system of claim 1, wherein the slot comprises a round end.

6. The system of claim 1, wherein the singulator further comprises a reinforcement panel that is attached to the side wall.

7. The system of claim 1, wherein a bottom edge of the slot in the side wall is substantially level with a top surface of the plurality of driven rollers.

8. The system of claim 1, wherein the singulator is configured to align the first packaged product with a plurality of additional packaged products in a single row.

9. The system of claim 1, wherein the guard comprises at least one of a door or a flap that covers the slot that forms the opening in the side wall.

10. The system of claim 1, wherein the slot comprises a vertical height configured to allow the second packaged product, but not the first packaged product, to be transported through the slot.

11. A system, comprising:

a singulator that comprises;

a side wall having a slot that forms an opening in the side wall, the slot having a horizontal length that is greater than a vertical height associated with the slot;

a guard that covers a portion of the slot in the side wall and restricts access to the singulator through the slot; and

at least one conveyor segment configured to;

receive a first packaged product;

transport the first packaged product to be positioned against the side wall by at least forcing the first packaged product along at least a portion of the at least one conveyor segment using a plurality of driven rollers having a plurality of axes that are skewed relative to the side wall;

transport the first packaged product along the side wall past the slot to an end of the at least one conveyor segment;

receive a second packaged product;

transport the second packaged product to be positioned against the side wall by at least forcing the second packaged product along the at least a portion of the at least one conveyor segment using the plurality of driven rollers;

transport the second packaged product along the side wall to the slot; and

transport the second packaged product through the slot part instead of to the end of the at least one conveyor segment; and

a container positioned proximate to the side wall and adjacent to the slot, the container being configured to receive the second packaged product after the second packaged product is transported through the slot in the side wall.

12. The system of claim 11, further comprising a conveyor path positioned proximate to the end of the singulator, the conveyor path being configured to:

receive the first packaged product from the singulator; and

transport the first packaged product to a scanning station.

13. The system of claim 11, wherein the guard comprises a door that covers the slot.

14. The system of claim 11, wherein the guard comprises a flap that covers the slot that forms the opening in the side wall.

15. The system of claim 14, wherein the flap comprises at least one of a polycarbonate panel or an acrylic panel.

16. A method, comprising:

receiving a first packaged product on at least one conveyor segment of a singulator;

transporting the first packaged product to a side wall of the singulator by at least forcing the first packaged product along at least a portion of the at least one conveyor segment using a plurality of driven rollers having a plurality of axes that are skewed relative to the side wall;

transporting, using the at least one conveyor segment, the first packaged product through a slot that forms an opening in the side wall, the slot having a horizontal length that is greater than a vertical height associated with the slot, the slot having a guard that covers a portion of the slot in the side wall and restricts access to the singulator through the slot;

receiving a second packaged product on the at least one conveyor segment of the singulator;

transporting the second packaged product to the side wall of the singulator by at least forcing the second packaged product along the at least a portion of the at least one conveyor segment using the plurality of driven rollers having the plurality of axes that are skewed relative to the side wall;

transporting, using the at least one conveyor segment, the second packaged product along the side wall; and

transporting, using the at least one conveyor segment, the second packaged product past the slot to an end of the at least one conveyor segment.

17. The method of claim 16, further comprising transporting, using the at least one conveyor segment, the first packaged product along the side wall of the singulator prior to transporting the first packaged product through the slot.

18. The method of claim 16, further comprising transporting the second packaged product from the end of the at least one conveyor segment to a scanning station.

19. The method of claim 16, further comprising receiving the first packaged product in a container that is located below the side wall of the singulator.

20. The method of claim 16, wherein a thickness of the first packaged product is less than or equal to a vertical height of the slot.
