Progressive modularity assortment system with high and low capacity bins
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 closed 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.
1. A removable modular sort bin for use in a stacker section of a mail sorting system, the modular sort bin comprising:
a tray for receiving mail pieces selectively diverted from a transport path of the stacker section;
an integral transport assembly at a rear end of the tray comprising a motor and a transport belt driven by the motor; and
a coupling, for operatively positioning and detachably securing the removable modular sort bin, including the tray, motor and transport belt, along the transport path of the stacker section, in a position where the driven transport belt cooperates with opposing elements of the stacker section to move mail pieces along the transport path and the tray receives the selectively diverted mail pieces.
2. The bin of claim 1 , wherein the coupling comprises:
a latch member adapted to secure the tray to a base support of the stacker section; and
a bin locating slot adapted to properly position the bin in the stacker section of the mail sorting system.
3. The bin of claim 1 , wherein the transport assembly comprises:
a main transport motor;
a main transport belt, driven by the main transport motor, for facilitating mail piece transport along a portion of the transport path;
a tray entry belt able to move diverted mail pieces into the tray; and
a counting and tracking sensor for sensing mail pieces.
4. The bin of claim 1 , further comprising a diverter mounted on the sort bin module, for selectively diverting mail pieces from the transport path to an opposing sort bin module.
5. A removable sort bin module for use in a stacker section of a mail sorting system, the sort bin module comprising:
a tray for receiving mail pieces selectively diverted from a transport path of the stacker section;
an integral transport assembly at a rear end of the tray comprising a motor and a transport belt driven by the motor for cooperation with an element of an opposing sort bin module mounted on a side of the transport path opposite the sort bin module, to move mail pieces along the transport path between the sort bin modules;
a diverter mounted on the sort bin module, for selectively diverting mail pieces from the transport path to the opposing sort bin module; and
a coupling, for operatively positioning and detachably securing the sort bin module, including the tray, motor and transport belt, along the transport path across from the opposing sort bin module.
6. The sort bin module of claim 5 , wherein the coupling comprises:
a latch member adapted to secure the tray to a base support of the stacker section; and
a bin locating slot adapted to properly position the bin in the stacker section.
7. The sort bin module of claim 5 , wherein, when activated to divert a mail piece, the diverter extends downstream and somewhat across the transport path toward the opposing sort bin module.
