Sideways sheet feeder and methods

1. A method for processing a series of sheets, the method comprising:

advancing, using an upper advancing mechanism, a batch of sheets from an upper feeder tray directly to a lower feeder tray positioned below and adjacent the upper feeder tray;

advancing a first sheet of the series of sheets from the lower feeder tray in a first direction to an alignment mechanism;

reading a first identification code from the first sheet;

advancing the first sheet in a second direction to an accumulator, wherein the second direction is substantially perpendicular to the first direction;

advancing a second sheet of the series of sheets from the lower feeder tray in the first direction to the alignment mechanism;

reading a second identification code from the second sheet; and

comparing the first identification code read from the first sheet with the second identification code read from the second sheet.

2. The method of claim 1 , further comprising advancing the second sheet in the second direction to match with the first sheet in the accumulator, if the second identification code corresponds with the first identification code.

3. The method of claim 2 , wherein advancing each sheet to the alignment mechanism comprises aligning the sheet with an alignment plate of the alignment mechanism.

4. The method of claim 2 , wherein advancing each sheet to the alignment mechanism comprises advancing a bottom sheet of a sheet stack to the alignment mechanism.

5. The method of claim 2 , wherein advancing each sheet to the alignment mechanism comprises verifying that a single sheet at a time is advanced to the alignment mechanism.

6. The method of claim 2 , wherein advancing each sheet to the alignment mechanism comprises verifying that each sheet is fully advanced to the alignment mechanism and is aligned within the alignment mechanism.

7. The method of claim 2 , wherein advancing each sheet to the accumulator comprises contacting each sheet with a friction wheel.

8. The method of claim 7 , wherein the friction wheel is in operative association with a rotary solenoid.

9. The method of claim 1 , wherein the identification code of each sheet comprises a bar code.

10. The method of claim 1 , wherein the identification code of each sheet comprises a set number identifier and a sequence number identifier.

11. The method of claim 1 , wherein reading the identification code comprises scanning the identification code with a laser scanner.

12. A system for processing a series of sheets, the system comprising:

an alignment mechanism comprising an alignment plate;

an upper feeder tray;

a lower feeder tray positioned below and adjacent the upper feeder tray;

an upper advancing mechanism that is configured to advance a batch of sheets from the upper feeder tray directly to the lower feeder tray;

a first advancing mechanism that is configured to individually advance each sheet of the series of sheets in a first direction from the lower feeder tray to the alignment mechanism;

a second advancing mechanism that is configured to individually advance each sheet of the series of sheets in a second direction from the alignment mechanism to an accumulator, wherein the second direction is substantially perpendicular to the first direction;

a sensor that is configured to read an identification code from each sheet of the series of sheets; and

a processor configured to compare a first identification code read from a first sheet of the series of sheets with a second identification code read from a second sheet of the series of sheets and to control operation of the first and second advancing mechanisms based on sensor readings of the identification codes.

13. The system of claim 12 , wherein the alignment mechanism comprises an alignment plate.

14. The system of claim 12 , further comprising a count sensor configured to verify that a single sheet at a time is advanced to the alignment mechanism.

15. The system of claim 12 , further comprising an orientation sensor configured to verify that each sheet is fully advanced to the alignment mechanism and is aligned within the alignment mechanism.

16. The system of claim 12 , wherein the second advancing mechanism comprises a friction wheel adapted to contact a sheet disposed in the alignment mechanism upon instructions from the processor.

17. The system of claim 16 , wherein the friction wheel is in operative association with a rotary solenoid.

18. The system of claim 12 , wherein the sensor comprises a laser scanner.

19. A computer program product for processing a series of sheets, the program product comprising:

code for advancing a batch of sheets from an upper feeder tray directly to a lower feeder tray positioned below and adjacent the upper feeder tray;

code for advancing a first sheet of the series of sheets from the lower feeder tray in a first direction to an alignment mechanism;

code for reading a first identification code from the first sheet;

code for advancing the first sheet in a second direction to an accumulator, wherein the second direction is substantially perpendicular to the first direction;

code for advancing a second sheet of the series of sheets from the lower feeder tray in the first direction to the alignment mechanism;

code for reading a second identification code from the second sheet;

code for comparing the first identification code read from the first sheet with the second identification code read from the second sheet; and

a computer-readable medium for storing the codes.

20. The computer program product of claim 19 , further comprising code for advancing the second sheet in the second direction to match with the first sheet in the accumulator, if the second identification code corresponds with the first identification code.
