Package unbundling system

1. An automatic unbundling system, comprising:

an input unit configured to receive polywrapped bundles each including a plurality of items;

a conveyor system configured to transport the polywrapped bundles;

an automatic unwrapping machine configured to receive each of the bundles from the conveyor system and unwrap each of the bundles, including centering and clamping each bundle, wherein the conveyor system then transports the unwrapped plurality of items away from the automatic unwrapping machine; and

a loose stack accumulator configured to receive, combine, and stack the unwrapped plurality of items from successive bundles.

2. The automatic unbundling system of claim 1 , wherein the conveyor system includes a bundle recognition and orientation verification unit that images each plurality of unwrapped items to create respective imaging information, and

wherein the conveyor system transports each plurality of unwrapped items into either the loose stack accumulator or a tray according to the respective imaging information.

3. The automatic unbundling system of claim 2 , further comprising at least one output lane that transports the plurality of items in the tray for further processing.

4. The automatic unbundling system of claim 3 , wherein the further processing includes sorting each of the plurality of items.

5. The automatic unbundling system of claim 1 , further comprising a tray-filling system that places the unwrapped plurality of items in a tray.

6. The automatic unbundling system of claim 1 , further comprising an automatic destrapping machine that automatically removes at least one strap from the bundle.

7. The automatic unbundling system of claim 6 , wherein the bundle is unwrapped before the at least one strap is removed from the bundle.

8. The automatic unbundling system of claim 6 , wherein different portions of the conveyor system transport the bundle to the automatic unwrapping machine and the automatic destrapping machine.

9. The automatic unbundling system of claim 1 , further comprising at least one bundle workstation where an operator can manually remove at least one strap from the bundle.

10. The automatic unbundling system of claim 1 , further comprising at least one bundle workstation where an operator can face, edge, or sort the bundle.

11. The automatic unbundling system of claim 1 , further comprising at least one manual tray filling station where an operator can move the unwrapped plurality of items to a tray.

12. The automatic unbundling system of claim 11 , wherein the manual tray filling station includes a proximity switch that, when activated, causes the automatic unbundling system to index a filled tray and advance an empty tray into a fill position.

13. The automatic unbundling system of claim 1 , further comprising an exception/reject chute that moves bundles that cannot be automatically processed into a position for manual processing.

14. An automatic unbundling system, comprising:

an input unit configured to receive polywrapped bundles each including a plurality of items, wherein the input unit is a container dumper receptacle;

a conveyor system configured to transport the polywrapped bundles;

an automatic unwrapping machine configured to receive each of the bundles from the conveyor system and unwrap each of the bundles, wherein the conveyor system then transports the unwrapped plurality of items away from the automatic unwrapping machine; and

a loose stack accumulator configured to receive, combine, and stack the unwrapped plurality of items from successive bundles.

15. An automatic unbundling system, comprising:

an input unit configured to receive a combination of strapped bundles and polywrapped bundles, each including a plurality of items;

a conveyor system configured to selectively transport the polywrapped bundles to an automatic unwrapping machine and to transport the strapped bundles to an automatic destrapping machine, and configured to transport each unwrapped or destrapped plurality of items away from the respective automatic unwrapping machine and automatic destrapping machine, the conveyor system further configured to transport each unwrapped or destrapped plurality of items to a loose stack accumulator,

wherein the automatic unwrapping machine is configured to receive each of the polywrapped bundles from the conveyor system and unwrap each of the polywrapped bundles, including centering and clamping each bundle,

wherein the automatic destrapping machine is configured to receive each of the strapped bundles from the conveyor system and destrap each of the strapped bundles,

wherein the loose stack accumulator is configured to receive, combine, and stack the unwrapped or destrapped plurality of items from successive bundles, and

wherein the conveyor system transports each unwrapped or destrapped plurality of items to a respective destination determined by imaging information from the respective unwrapped or destrapped plurality of items.

16. The automatic unbundling system of claim 15 , wherein the conveyor system selectively transports the polywrapped bundles and the strapped bundles according to a placement of each bundle on the conveyor system by an operator.

17. A method, comprising:

receiving a polywrapped bundle at an input unit, the bundle including a plurality of items;

transporting the bundle to an automatic unwrapping machine;

automatically unwrapping the bundle using the automatic unwrapping machine, including centering and clamping each bundle;

transporting the unwrapped plurality of items on a conveyor;

receiving, combining, and stacking the unwrapped plurality of items from successive bundles using a loose stack accumulator; and

placing the unwrapped plurality of items in a tray.

18. The method of claim 17 , further comprising destrapping the bundle using an automatic destrapping machine.
