Abstract

The dynamic package sortation device includes a track for handling a plurality of packages is provided. At least one conveyor extends away from the track towards at least two shipping containers. The at least one conveyor is extendable and retractable for dispensing the packages into a first shipping container of the at least two shipping containers and a second condition for dispensing the packages into a second shipping container of the at least two shipping containers. A controller is provided for providing an instruction to move the at least one conveyor between the first condition and the second condition based on a trigger.

First claim

What is claimed is:

1. A sortation device comprising:
a track for handling a plurality of packages;
a plurality of conveyors extending at angles away from the track towards respective sets of containers, each set of containers including at least two shipping containers;
a plurality of swing gates for redirecting the packages from the track onto the plurality of conveyors;
at least one conveyor of the plurality of conveyors being extendable from a first condition for dispensing the packages that are redirected from the track onto the at least one conveyor into a first shipping container of the at least two shipping containers in the respective set of containers and a second condition for dispensing the packages that are redirected from the track onto the at least one conveyor into a second shipping container of the at least two shipping containers in the respective set of containers;
a controller providing an instruction to move the at least one conveyor between the first condition and the second condition based on a trigger.

2. The sortation device as set forth in claim 1 wherein the at least one conveyor includes a first belt and a second belt and wherein at least one of the first and second belts can be moved relative to the other of the first and second belts.

3. The sortation device as set forth in claim 2 wherein the first belt is an upper belt and the second belt is a lower belt that is located vertically below the upper belt.

4. The sortation device as set forth in claim 3 wherein the lower belt can move from a first position that is directly below the upper belt and a second position with the lower belt extending past the upper belt.

5. The sortation device as set forth in claim 4 wherein the lower belt includes at least two pulleys that are operably coupled with at least one pulley track that guides the movement of the lower belt relative to the upper belt.

6. The sortation device as set forth in claim 1 , wherein the first and second shipping containers are arranged adjacent one another in a direction of extension of the at least one conveyor.

7. The sortation device as set forth in claim 1 , wherein the swing gates that are located along the track, and wherein the swing gates are able to articulate between a non-deflecting position and a deflecting position, and wherein the swing gates can deflect the packages from the track to the conveyors when the swing gates are in the deflecting position.

8. A method of dispensing a plurality of packages into a plurality of shipping containers, comprising the steps of:
preparing a track and a plurality of conveyors that extend at angles away from the track towards respective sets of shipping containers, each of the sets of shipping containers including a first shipping container and a second shipping container;
guiding the plurality of packages along the track;
deflecting at least one of the packages from the track onto a first conveyor of the plurality of conveyors and then into the first shipping container of the respective set of shipping containers;
extending the first conveyor; and
deflecting at least one of the packages onto the first conveyor and then into the second shipping container of the respective set of shipping containers.

9. The method as set forth in claim 8 wherein the first conveyor includes a first belt and a second belt, and wherein
the step of extending the first conveyor includes moving one of the first and second belts relative to the other of the first and second belts.

10. The method as set forth in claim 9 wherein the first belt is an upper belt and the second belt is a lower belt, and wherein
the step of extending the first conveyor includes moving the lower belt from a retracted position vertically below the upper belt to an extended position where the lower belt extends outwardly past an end of the upper belt.

11. The method as set forth in claim 10 wherein the lower belt includes at least two pulleys that are disposed along at least one pulley track and wherein movement of the lower belt involves moving the at least two pulleys along the at least one pulley track.

12. The method as set forth in claim 8 wherein each of the plurality of conveyors is extendable and retractable and is configured to deposit packages into one shipping container when in a retracted condition and into another shipping container when in an extended condition.

13. The method as set forth in claim 12 wherein the plurality of conveyors can be extended and retracted independently of one another.

14. The method as set forth in claim 8 further including the step of determining with a controller if a trigger event has occurred and wherein the step of extending the at least one conveyor takes place in response to the controller determining that the trigger event has occurred.

15. The method as set forth in claim 14 wherein the trigger event is a predetermined time.

16. A package sortation assembly, comprising:
a main track for handling a plurality of packages;
a plurality of sets of shipping containers, the plurality of sets of shipping containers including at least two shipping containers arranged adjacent one another;
a plurality of conveyors that are spaced apart from one another along the main track, the conveyors extending at angles relative to the main track from the main track towards respective ones of the sets of shipping containers, the conveyors being individually extendable and retractable;
a plurality of swing gates for redirecting the packages from the main track onto the plurality of conveyors; and
a controller in communication with the plurality of conveyors and configured to selectively extend and retract the conveyors to control which shipping containers in the sets the packages are dispensed into.

17. The package sortation assembly as set forth in claim 16 wherein each conveyor of the plurality of conveyors includes a first belt and a second belt and wherein at least one of the first and second belts can be moved relative to the other of the first and second belts.

18. The package sortation assembly as set forth in claim 17 wherein the first belt is an upper belt and the second belt is a lower belt that is located vertically below the upper belt.

19. The package sortation assembly as set forth in claim 18 wherein the lower belt can move from a first position that is directly below the upper belt and a second position with the lower belt extending past the upper belt.
