Adjustable Tray Rack

Abstract

A machine to sort documents includes a stacker having a tier of the plurality of pockets and a magazine positioned at one end of the stacker. A first transport and a second transport operably associated with the magazine are configured to carry the documents through the stacker. Once the sorted documents are at the end of the machine, there is a tray system operably associated with the machine to allow the user to store the resulting sorted documents from the machine.

What is claimed is: 
     
         1 . A tray system to store documents, the tray system comprising:
 a first row of a plurality of removable trays associated with a first scheme;   a second row of a plurality of removable trays associated with a second scheme;   a lift subsystem operably associated with the first row and the second row, the lift subsystem being adapted to raise and lower the first row and the second row; and   a drive subsystem operably associated with the lift subsystem, the drive subsystem being adapted to drive the lift subsystem;   wherein the tray system allows switching between the first row and the second row.   
     
     
         2 . The tray system of  claim 1 , the lift subsystem comprising:
 a first gear;   a second gear; and   a chain rotatably coupled to the first gear and the second gear.   
     
     
         3 . The tray system of  claim 1 , further comprising:
 a manual switch.   
     
     
         4 . The tray system of  claim 1 , further comprising:
 a switch configured to be remotely controlled by a computer.   
     
     
         5 . The tray system of  claim 1 , further comprising:
 a first position; and   a second position;   wherein the first row and second row are moved between the first position and the second position to limit access.   
     
     
         6 . The tray system of  claim 5 , further comprising:
 a blockout panel adjacent to the first position.   
     
     
         7 . A tray system to store sorted documents, comprising:
 a mail sorting machine;   a first shelf associated with a first scheme;   a second shelf associated with a second scheme;   a lift subsystem configured for raising and lowering the first shelf and the second shelf;   a drive subsystem configured for driving the lift subsystem; and   a control subsystem.   
     
     
         8 . The tray system of  claim 7 , the lift subsystem comprising:
 a first gear;   a second gear; and   a chain rotatably coupled to the first gear and the second gear.   
     
     
         9 . The tray system of  claim 7 , the control subsystem comprising:
 a switch operably associated with the lift subsystem.   
     
     
         10 . The tray system of  claim 9 , wherein the switch is controlled by the mail sorting machine based upon which scheme the mail sorting machine is processing. 
     
     
         11 . The tray system of  claim 7 , further comprising:
 a blocked position; and   an accessible position;   wherein the first shelf and second shelf are moved between the blocked position and the accessible position to limit access.   
     
     
         12 . The tray system of  claim 11 , further comprising:
 a panel adjacent to the blocked position.   
     
     
         13 . A automated shelving system, comprising:
 a first shelf;   a second shelf;   a lifting system operably associated with the first shelf and with the second shelf, the lifting system configured to move the first shelf between an exposed position and a hidden position;   a drive subsystem operably associated with the lifting system; and   a control subsystem configured for controlling the lifting system.   
     
     
         14 . The automated shelving system of  claim 13 , further comprising:
 a blockout panel, wherein the blockout panel is configured for blocking access to shelves located in the hidden position.   
     
     
         15 . The automated shelving system of  claim 13 , the lifting system comprising:
 a first gear;   a second gear; and   a chain rotatably coupled to the first gear and the second gear.   
     
     
         16 . The automated shelving system of  claim 13 , the control subsystem comprising:
 a switch operably associated with the lifting system;   wherein the switch is configured to be remotely controlled by a computer.   
     
     
         17 . The automated shelving system of  claim 13 , the control subsystem comprising:
 a switch operably associated with the lifting system;   wherein the switch is configured to be controlled a user.   
     
     
         18 . The automated shelving system of  claim 16 , wherein the computer is in control of a mail sorting machine.
