Abstract

A system includes a forming funnel, a cutting element, and a fusing device. The forming funnel has divergent surfaces arranged to receive a mailer in an insertion direction between the divergent surfaces. The forming funnel includes a slot that constrains the mailer after the mailer is inserted between the divergent surfaces. The cutting element cuts off a portion of the mailer and to forms a cut end of the mailer as the mailer is moved through the slot in a sliding direction. The fusing device applies pressure to an exterior of the cut end of the mailer and applies heat to the cut end of the mailer as the mailer is moved through the slot. The pressure and the heat applied by the fusing device cause portions of the cut end to fuse together to close the mailer.

First claim

What is claimed is:

1. A system comprising:
a forming funnel comprising divergent surfaces arranged to receive a mailer in an insertion direction between the divergent surfaces, wherein the forming funnel includes a slot configured to constrain the mailer after the mailer is inserted between the divergent surfaces;
a cutting element configured to cut off a portion of the mailer and to form a cut end of the mailer as the mailer is moved through the slot in a sliding direction; and
a fusing device configured to apply pressure to an exterior of the cut end of the mailer as the mailer is moved through the slot and to apply heat to the cut end of the mailer as the mailer is moved through the slot, wherein the pressure and the heat applied by the fusing device cause portions of the cut end to fuse together to close the mailer.

2. The system of claim 1 , wherein the insertion direction is substantially perpendicular to the sliding direction.

3. The system of claim 1 , wherein the fusing device further comprises:
a first set of rollers on a first side of the slot, wherein the first set of rollers is configured to contact a first side of the exterior of the cut end of the mailer as the cut end of the mailer is moved through the slot; and
a second set of rollers on a second side of the slot, wherein the second set of rollers is configured to contact a second side of the exterior of the cut end of the mailer as the cut end of the mailer is moved through the slot;
wherein the first and second sets of rollers are configured to apply the pressure to the exterior of the cut end of the mailer.

4. The system of claim 3 , wherein the fusing device further comprises:
a conveying system configured to convey the cut end of the mailer through the at least a portion of the slot that includes the first and second sets of rollers.

5. The system of claim 4 , wherein the conveying system includes a continuous band arranged to pass along the first set of rollers.

6. The system of claim 5 , further comprising a driving system configured to drive the continuous band.

7. The system of claim 6 , wherein the mailer is configured to be inserted into the forming funnel manually and moved in the sliding direction manually until the cut end of the mailer reaches the continuous band, and wherein the driving of the continuous band moves the mailer in the sliding direction through the first and second sets of rollers.

8. The system of claim 3 , wherein the exterior of the cut end of the mailer include a first ply of paper on the first side of the exterior of the cut end and a second ply of paper on the second side of the exterior of the cut end, wherein an inner surface of each of the first and second plies of paper has an air cellular material adhered thereto.

9. The system of claim 8 , wherein the pressure and the heat applied to the cut end of the mailer causes at least a portion of the air cellular material on the first ply of paper to fuse with at least a portion of the air cellular material on the second ply of paper.

10. The system of claim 8 , wherein the portions of the cut end fused together to close the mailer include a heat seal in the air cellular material on the first and second plies of paper, wherein the heat seal is formed by the pressure and the heat applied by the fusing device.

11. The system of claim 1 , wherein the fusing device further comprises:
an upper heating element configured to apply heat to an upper side of the cut end of the mailer; and
a lower heating element configured to apply heat to a lower side of the cut end of the mailer.

12. The system of claim 11 , wherein the fusing device further comprises:
an upstream set of nip rollers located upstream of the upper and lower heating elements, wherein the upstream set of nip rollers are configured to apply pressure to the cut end of the mailer before the cut end of the mailer passes between the upper and lower heating elements; and
a downstream set of nip rollers located downstream of the upper and lower heating elements, wherein the downstream set of nip rollers are configured to apply pressure to the cut end of the mailer after the cut end of the mailer passes between the upper and lower heating elements.

13. The system of claim 1 , further comprising a back cover, wherein the back cover covers portions of a back of the forming funnel, and wherein the back cover does not cover the slot in the forming funnel.

14. The system of claim 13 , wherein the back cover covers portions of the slot in the fusing device.

15. The system of claim 1 , further comprising:
a labelling mechanism configured to apply a shipping label to the mailer after the portion of the mailer has been cut off by the cutting element.

16. The system of claim 15 , wherein the shipping includes shipping information based on dimensions of the mailer after the portion of the mailer has been cut off by the cutting element.

17. A method of preparing a mailer for shipment, the method comprising:
receiving, into a slot of a forming funnel, a mailer that has an object placed therein, wherein the mailer is capable of being inserted through the slot until a size of the object prevents the mailer from being further inserted through the slot;
cutting off, by a cutting element as the mailer is slid through the slot in a sliding direction, a portion of the mailer to form a trimmed mailer having a cut end;
closing, by a fusing device, the cut end of the trimmed mailer as the trimmed mailer is further slid through the slot in the sliding direction;
identifying, by a computing device, one or more dimensions of the trimmed mailer;
determining, by a computing device, shipping information for the trimmed mailer, wherein the shipping information is determined based on the identified one or more dimensions of the trimmed mailer; and
printing or applying, by a labelling mechanism, the shipping information on the trimmed mailer.

18. The method of claim 17 , further comprising:
scanning, by a scanning device, an identifier of a packing list; and
identifying, by the computing device, a weight of the objected based on the identifier of the packing list.

19. The method of claim 18 , further comprising:
scanning, by a scanning device, an identifier of a mailer type of the mailer;
identifying, by the computing device, a density of the mailer based the identifier of the packing list; and
calculating a weight of the trimmed mailer based on the density of the mailer and the identified one or more dimensions of the trimmed mailer.

20. The method of claim 19 , further comprising:
calculating, by the computing device, a weight of a package that includes the object and the trimmed mailer based on the weight of the object and the weight of the trimmed mailer.

21. The method of claim 20 , further comprising:
sensing, by a dimension sensor, a height of the trimmed mailer; and
calculating, by the computing device, total dimensions of the trimmed mailer based on the sensed height of the trimmed mailer and the identified one or more dimensions of the trimmed mailer.

22. The method of claim 21 , further comprising:
calculating, by the computing device, a dim weight of the trimmed mailer based on the total dimensions of the trimmed mailer.

23. The method of claim 22 , wherein determining the shipping information includes comparing the weight of the package to the dim weight of the trimmed mailer.
