Abstract

A sorting system configured to sort materials by size, and/or weight is disclosed herein. The sorting system is configured to operate in a smaller footprint as compared with conventional sorting systems. For instance, a main sorting track of sorting system is configured to deliver sorted material to either side of the main sorting track. Additionally, the sorting system is configured to reduce mechanical damage imparted on the material to be sorted by sorting system by a sliding and/or rolled delivery. Aspects of the sorting system may be mounted on a mobile platform.

Claims

1. A sorting system comprising:

a main sorting track comprising a plurality of hinged members, wherein a subset of said plurality of hinged members passively pivot to deliver sorted material to a location on either side of the main sorting track, wherein each hinged member of the plurality of hinged members may pivot to either side of the main sorting track, wherein the subset of the plurality of hinged members, which are configured to work in tandem, is determined based on at least one of the sensed leading edge of a material to be sorted and a sensed trailing edge of the material to be sorted, wherein the subset of the plurality of hinged members are slaved together via programing based on at least one of the sensed leading edge of the material to be sorted and the sensed trailing edge of the material to be sorted.

2. The sorting system of claim 1, wherein each hinged member of the plurality of hinged members is coupled to a pivot structure at a single pivot location.

3. The sorting system of claim 2, wherein the pivot structure is coupled to an anchor chain structure, wherein adjacent anchor chain structures are coupled together to form a drive belt.

4. The sorting system of claim 1, further comprising stationary guide rails to orient a position of each hinged member of the plurality of hinged members.

5. The sorting system of claim 4, further comprising a pivoting guide track system to orient each hinged member of said subset of the plurality of hinged members in a pivoted orientation.

6. The sorting system of claim 5, wherein the pivoting guide track system is fixed in a stationary position along the main sorting track.

7. The sorting system of claim 1, wherein the hinged members comprise an elongated V shaped top surface.

8. The sorting system of claim 1, wherein the sorting system is configured to sort materials based on at least one of a size and a weight of the material.

9. The sorting system of claim 1, further comprising a flanking conveyor belt adjacent to a side of the main sorting track.

10. The sorting system of claim 9, wherein said flanking conveyor belt operates in an opposite direction than the direction of operation of the main sorting track.

11. The sorting system of claim 9, wherein the main sorting track and the flanking conveyor belt are mounted on a mobile platform configured to be towed by a vehicle.

12. The sorting system of claim 1, further comprising a delivery conveyor belt in line with and in communication with the main sorting track, wherein the delivery conveyor belt comprises targets for placing materials to be sorted.

13. The sorting system of claim 12, wherein the targets are outlined by a series of raised deformable tabs.

14. The sorting system of claim 1, wherein a sensor senses the leading edge and the trailing edge of the material to be sorted.

15. A mobile sorting system comprising;

a main sorting track comprising a plurality of hinged members, wherein a subset of the plurality of hinged members deliver sorted material to a location on either side of the main sorting track via passively pivoting on an axis, wherein each hinged member of the plurality of hinged members may pivot to either side of the main sorting track, wherein a subset of the plurality of hinged members, which are configured to work in tandem, is determined based on at least one of a sensed leading edge of a material to be sorted and a sensed trailing edge of the material to be sorted, wherein the subset of plurality of hinged members are slaved together via programing based on at least one of the sensed leading edge of the material to be sorted and the sensed trailing edge of a material to be sorted; and

a mobile platform, wherein the main sorting track is integrally coupled to the mobile platform.

16. The mobile sorting system of claim 15, wherein the mobile platform is configured to be towed by a vehicle.

17. The mobile sorting system of claim 15, further comprising a flanking conveyor belt integrally coupled to the mobile platform, wherein the flanking conveyor belt is located adjacent to a side of the main sorting track.
