Sorting system
A sorting system includes one or a plurality of transporter units, at least one loading station for loading a parcel onto transporter units, a plurality of destination stations, and a network of paths, each path including at least one track, the network including a plurality of junctions where at least two of the paths intersect. Each transporter unit is controllable to travel along the paths of the network of paths and to continue travelling along one of the at least two paths at a junction. A controller is configured to calculate a route within the network of paths between a loading station and a selected destination station, and to control the transporter unit to travel along the calculated route.
1. A sorting system comprising:
one or a plurality of transporter units;
at least one loading station for loading a parcel onto a transporter unit of the one or a plurality of transporter units;
a plurality of destination stations;
a network of paths, the network of paths comprising:
at least one thoroughfare path;
a plurality of distribution paths, the plurality of destination stations being distributed along each distribution path of the plurality of distribution paths;
each path of the network of paths comprising at least one track and including a plurality of junctions where at least two of the paths intersect, each transporter unit being controllable to travel along the paths of the network of paths and to continue travelling along one of said at least two paths at a junction of the plurality of junctions;
wherein each distribution path comprises two ends, a first end intersecting a thoroughfare path, and a second end terminating in a connecting loop;
wherein each intersection between two intersecting paths or between a path and a junction forms an acute angle opening toward a new direction of travel, configured to divert transporter units from an existing direction of travel to a new direction of travel; and
a controller configured to calculate a route within the network of paths between a loading station of said at least one loading station and a selected destination station of the plurality of destination stations, and to control the transporter unit to travel along the calculated route.
2. The system of claim 1 , wherein the network of paths comprises paths on at least two levels at different heights, and wherein the plurality of junctions comprises at least one vertical junction between a path one of the levels and a path on another of the levels.
3. The system of claim 2 , wherein the vertical junction comprises an elevator.
4. The system of claim 1 , wherein a loading station of said at least one loading station is located at an end of the thoroughfare path.
5. The system of claim 1 , wherein each distribution path of the plurality of distribution paths is located at an end of a thoroughfare path of a grid of intersecting thoroughfare paths.
6. The system of claim 5 , wherein a loading station of said at least one loading station is located at a distal end of a distribution path of the plurality of distribution paths.
7. The system of claim 1 , further comprising a reader configured to read a label on the parcel.
8. The system of claim 7 , wherein the controller is configured to select a destination station for delivery of the parcel based on contents of the label.
9. The system of claim 1 , wherein a destination station of the plurality of destination stations comprises a bin or sack.
10. The system of claim 1 , wherein the transporter unit comprises a vehicle that is configured to travel on the network of paths.
11. The system of claim 1 , wherein the network of paths is configured to enable travel of the transporter unit in a single direction along each track of said at least one track.
12. The system of claim 11 , wherein a path of the network of paths comprises two tracks, wherein the direction of travel along one of the two tracks is opposite the direction of travel along the other track of the two tracks.
13. The system of claim 12 , wherein the two tracks terminate in a loop that enables the transporter unit to travel from one of the two tracks to the other.
14. The system of claim 1 , wherein a junction of the plurality of junctions comprises a roundabout.
15. The system of claim 1 , wherein the network of paths comprises a parking area for parking at least one transporter unit.
16. The system of claim 1 , wherein the network of paths comprises a maintenance area to enable maintenance on a transporter unit.
17. The system of claim 1 , wherein the controller is configured to detect a location of the transporter unit on the network of paths.
18. The system of claim 1 , wherein the controller is configured to calculate the route such that a travel time of the transporter unit along the network of paths from the loading station to the selected destination station is minimized.
19. The system of claim 1 , wherein a path of the network of paths comprises a peripheral path that surrounds other paths of the network of paths.
