Abstract

A modular bin or pocket has an integrated transport assembly and mail piece diverter assembly and is usable in a bin stacker section in mail handling and sorting systems. The modular bin is individually removable, interchangeable and replaceable from the bin stacker sections of the mail processing system to allow for repair or maintenance of malfunctioning bins leading to reduced down time of the mail processing system. The modular bin further enables vertical and/or horizontal progressive modularity, i.e., vertical and/or horizontal expansion, of the bin stacker sections of the mail processing system which allows for cost-effective expansion of mail handling systems. Further, there is disclosed a tray management system and a tier diverter system that are usable in mail handling systems that use the modular bin with double sided bin stacker sections or single sided bin stacker sections with or without a turnaround section.

Claims

1. A modular stacker section for use in a mail sorting system, the modular stacker section comprising:

a frame;

one or more base supports attached to the frame providing a horizontal arrangement of a plurality of bin attachment points; and

a plurality of sort bin modules operatively positioned and detachably secured at the bin attachment points, each of the sort bin modules comprising;

(a) a tray for receiving mail pieces diverted from a transport path of the stacker section;

(b) a motor;

(c) a belt driven by the motor; and

(d) a coupling for operatively positioning and detachably securing the sort bin module to one of the bin attachment points,

wherein the belts of the sort bin modules participate in moving mail pieces along the transport path of the stacker section, and wherein;

at least one of the sort bin modules has a tray of a first size providing a first capacity to receive mail pieces;

at least one other sort bin module has a tray of a second size larger than the first size so as to provide a second capacity to receive a larger number of mail pieces than the first capacity; and

each attachment point is compatible with the sort bin modules of the first and second capacities.

2. The modular stacker section of claim 1, wherein the attachment points and coupling enable any sort bin module of the first size and any sort bin module of the second size to be detachably secured to any of the bin attachment points.

3. A vertical stacker section for use in a mail sorting system, the vertical stacker section comprising a first tier and a second tier, wherein:

the first tier comprises;

a bottom base support system,

a first modular bin attached to the bottom base support system, and

a second modular bin attached to the bottom base support system; and

the second tier is located above the first tier, and the second tier comprises;

a mounting post attached to the bottom base support system,

a tier base support attached to the mounting post,

a third modular bin attached to the tier base support, and

a fourth modular bin attached to the tier base support, wherein

wherein each modular bin includes a latching member for operatively positioning the bin and securing the modular bin.

4. The vertical stacker section of claim 3, wherein the base support system comprises:

an adjustable support for leveling the base support system with respect to a supporting floor;

a transport roller for rolling trays inside of the base support system; and

a slide tray for storing mail.

5. The vertical stacker section of claim 3, further comprising a third tier located above the second tier, and wherein the third tier comprises:

an additional mounting post attached to the tier base support of the second tier,

an additional tier base support attached to the additional mounting post,

a fifth modular bin attached to the additional tier base support, and

a sixth modular bin attached to the additional tier base support.

6. The vertical stacker section of claim 3, further comprising an upper rack configuration located above the second tier, wherein the upper rack configuration comprises:

a) one or more additional mounting posts attached to the tier base support of the second tier,

b) an upper rack support base attached to at least one of the one or more additional mounting posts, and

c) an upper rack attached to the upper rack support base.

7. The vertical stacker section of claim 3, wherein the base support system comprises a slide tray for storing mail.

8. The vertical stacker section of claim 3, wherein each of the modular bins may be modularly interchanged with any of the other modular bins.

9. A vertical stacker section for use in a mail sorting system, the vertical stacker section comprising a first tier and a second tier, wherein:

the first tier comprises;

a bottom base support system,

a first modular bin attached to the bottom base support system, and

a second modular bin attached to the bottom base support system; and

the second tier is located above the first tier, and the second tier comprises;

a mounting post attached to the bottom base support system,

a tier base support attached to the mounting post,

a third modular bin attached to the tier base support, and

a fourth modular bin attached to the tier base support, wherein each modular bin comprises;

(a) a tray for receiving mail pieces diverted from a transport path of the stacker section;

(b) a transport assembly comprising a motor and a belt driven by the motor; and

(c) a flange with a slot and a hole, wherein the slot and the hole are configured for attachment to the bottom base support, and also configured for attachment to the base support for the second tier.

10. A vertical stacker section for use in a mail sorting system, the vertical stacker section comprising a first tier and a second tier, wherein:

the first tier comprises;

a bottom base support system,

a first modular bin attached to the bottom base support system, and

a second modular bin attached to the bottom base support system, and

the second tier is located above the first tier, and the second tier comprises;

a mounting post attached to the bottom base support system,

a tier base support attached to the mounting post,

a third modular bin attached to the tier base support, and

a fourth modular bin attached to the tier base support,

wherein at least one modular bin has a tray of a first size, and at least one modular bin has a tray of a second size larger than the first size.

11. A vertically modular stacker section for use in a mail sorting system, the stacker section comprising:

a first sort bin tier, comprising;

a) a bottom base support system, having a horizontal arrangement of points for attachment of sort bins; and

b) a first plurality of sort bins for receiving sorted mail pieces, attached to the points of the horizontal arrangement of the bottom base support system;

a second sort bin tier, comprising;

1) a plurality of mounting posts;

2) a tier base support attached to the mounting posts, having a horizontal arrangement of points for attachment of sort bins; and

3) a second plurality of sort bins for receiving sorted mail pieces, attached to the points of the horizontal arrangement of the tier base support;

fasteners for modularly attaching the mounting posts of the second sort bin tier to the base support system of the first sort bin tier, to attach the second sort bin tier to and above the first sort bin tier; and

one or more conveyor paths for conveying mail pieces to the first and second sort bins,

wherein each of the second plurality of sort bins is a modular sort bin, configured for attachment to and detachment from any of the points of the horizontal arrangement of the tier base support.

12. The stacker section of claim 11, wherein:

each of the first plurality of sort bins is a modular sort bin, configured for attachment to and detachment from any of the points of the horizontal arrangement of the bottom base support system.
