Abstract

An apparatus that substantially improves the stack quality of delivery items in a delivery item sorting machine by ensuring uniformity of the orientation of the delivery items. The apparatus accommodates toolless installation in the delivery item sorting machine and economical manufacturing options. The apparatus substantially prevents delivery item disorientation and undesired departure of delivery items from the sorting machine. The apparatus reduces operator safety concerns, and increases the net speed of delivery item processing.

First claim

What is claimed is:

1. A sorting machine apparatus for orienting a delivery item, the sorting machine apparatus comprising:
a bumper; and
a coupling feature connected to the bumper,
wherein the coupling feature operably couples the sorting machine apparatus with a sorting machine such that the bumper is positioned to align with an upper portion of the delivery item, and
wherein the coupling feature comprises a clip, and the clip comprises:
a semi-rigid arm having a first end and a second end, the first end being substantially curved; and
a rigid wall operably coupled with the semi-rigid arm at the first end.

2. The sorting machine apparatus of claim 1 wherein the bumper and the coupling feature comprise a single structure.

3. The sorting machine apparatus of claim 1 wherein the rigid wall comprises a lip.

4. The sorting machine apparatus of claim 1 wherein the semi-rigid arm comprises a mitre fillet.

5. The sorting machine apparatus of claim 1 wherein the coupling feature comprises a set screw.

6. The sorting machine apparatus of claim 1 comprising a metal material.

7. The sorting machine apparatus of claim 1 comprising a plastic material.

8. The sorting machine apparatus of claim 1 , further comprising:
a tab operably coupled with the bumper, the tab extending from a lower edge of the bumper.

9. The sorting machine apparatus of claim 1 , wherein the bumper includes an angled feature that is configured to guide a paddle away from the sorting machine apparatus.

10. A delivery item sorting machine apparatus coupled with a delivery item sorting machine, the delivery item sorting machine including a series of belts configured to transport at least one delivery item past at least one diverter, the at least one diverter configured to sort the at least one delivery item into an output bin that collects sorted delivery items, the delivery item sorting machine apparatus comprising:
a bumper configured with a spatial extension to the output bin; and
a coupling feature operably securely coupling the bumper with the output bin,
wherein the coupling feature comprises a clip, and the clip comprises:
a semi-rigid arm having a first end and a second end, the first end being substantially curved; and
a rigid wall operably coupled with the semi-rigid arm at the first end.

11. The delivery item sorting machine apparatus of claim 10 further comprising:
a paddle operating cooperatively with the bumper, the paddle and the bumper bounding the at least one delivery item on two sides as the at least one delivery item is directed into the output bin.

12. The delivery item sorting machine apparatus of claim 10 further comprising:
a backstop operably coupled with the output bin, wherein the coupling feature is
configured to create a secure coupling between the bumper and the backstop.

13. The delivery item sorting machine apparatus of claim 10 wherein the rigid wall comprises:
a lip extending towards the semi-rigid arm, the lip being configured to prevent the bumper from becoming disengaged from the output bin.

14. The delivery item sorting machine apparatus of claim 10 wherein the semi-rigid arm comprises:
a fillet extending away from the rigid wall, the fillet configured to aid in installation and removal of the bumper.

15. The delivery item sorting machine apparatus of claim 10 wherein the spatial extension comprises:
a height extension.

16. The delivery item sorting machine apparatus of claim 10 wherein the bumper comprises:
a dampening pad configured to reduce a force transmitted as the at least one delivery item contacts the bumper.

17. The delivery item sorting machine apparatus of claim 10 wherein the coupling feature comprises:
an accommodation for at least one of a bolt, a magnet, a rivet, a pin, an adhesive, or hook-and-eye material.

18. The delivery item sorting machine apparatus of claim 10 , wherein the bumper includes an angled feature that is configured to guide a paddle away from the sorting machine apparatus.

19. The delivery item sorting machine apparatus of claim 10 , wherein the rigid wall comprises a lip.

20. The delivery item sorting machine apparatus of claim 10 , wherein the semi-rigid arm comprises a mitre fillet.
