Abstract

A system for collating a plurality of media including a first bin, a second bin arranged adjacent to the first bin, a collated stack receiver arranged proximate the second bin opposite the first bin, three guides, a movable wall arranged generally perpendicular relative to the three guides, and a pusher. The movable wall is translatable in a process direction. When the guides are positioned in non-retracted locations, a first set of the plurality of media is deposited in the first bin and a second set of the plurality of media is deposited in the second bin, and when the guides are positioned in retracted locations, the pusher moves the first set to the second bin vertically above the second set to form a combined set and moves the combined set to the collated stack receiver. The position of the movable wall varies based on characteristics of the plurality of media.

First claim

What is claimed is:

1. A system for collating a plurality of media comprising:
a first bin;
a second bin arranged adjacent to the first bin;
a collated stack receiver arranged proximate the second bin opposite the first bin;
first, second and third guides, the first and second guides positioned on opposing sides of the first bin, and the second and third guides positioned on opposing sides of the second bin;
a movable wall arranged generally perpendicular relative to the first, second and third guides, the movable wall and the first, second and third guides forming three sides of the first and second bins, the movable wall is translatable in a process direction;
a pusher,
wherein when the first, second and third guides are positioned in non-retracted locations, a first set of the plurality of media is deposited in the first bin and a second set of the plurality of media is deposited in the second bin, and when the first, second and third guides are positioned in retracted locations, the pusher moves the first set to the second bin vertically above the second set to form a first combined set and moves the first combined set to the collated stack receiver, and
wherein a position of the movable wall is varied based on characteristics of the plurality of media.

2. The system of claim 1 further comprising:
a fixed wall arranged generally perpendicular relative to the first, second and third guides,
wherein the fixed wall, the movable wall and the first, second and third guides form four sides of the first and second bins and the position of the movable wall relative to the fixed wall is varied based on characteristics of the plurality of the media.

3. The system of claim 1 wherein the first and second bins each comprises a front portion, a rear portion and a gap separating the front portion and the rear portion, the gap of the first bin is aligned with the gap of the second bin.

4. The system of claim 3 wherein the pusher moves in a cross process direction within the gap.

5. The system of claim 3 wherein the movable wall is secured to the front portion of the first bin and the front portion of the second bin.

6. The system of claim 5 wherein at least one of a width of the gap of the first bin and a width of the gap of the second bin is changed during translation of the movable wall.

7. The system of claim 6 wherein the width of the gap of the first bin is less than the width of the gap of the second bin.

8. The system of claim 5 further comprising:
a fixed wall arranged generally perpendicular relative to the first, second and third guides,
wherein the fixed wall, the movable wall and the first, second and third guides form four sides of the first and second bins, a position of the pusher is maintained in a central location between the fixed wall and the movable wall during translation of the movable wall and the position of the movable wall relative to the fixed wall is varied based on characteristics of the plurality of the media.

9. The system of claim 1 wherein the first and second bins form a continuous surface and the movable wall complimentarily aligns with the continuous surface.

10. The system of claim 9 further comprising:
a fixed wall arranged generally perpendicular relative to the first, second and third guides,
wherein the fixed wall, the movable wall and the first, second and third guides form four sides of the first and second bins, at least one of a distance between a portion of the fixed wall and a portion of the movable wall forming the first bin and a distance between a portion of the fixed wall and a portion of the movable wall forming the second bin is changed during translation of the movable wall, and the distance between the portion of the fixed wall and the portion of the movable wall forming the first bin and/or the distance between the portion of the fixed wall and the portion of the movable wall forming the second bin is varied based on characteristics of the plurality of the media.

11. The system of claim 10 wherein the distance between the portion of the fixed wall and the portion of the movable wall forming the first bin is less than the distance between the portion of the fixed wall and the portion of the movable wall forming the second bin.

12. A method for collating a plurality of media in a system comprising a first bin, a second bin arranged adjacent to the first bin, a collated stack receiver arranged proximate the second bin opposite the first bin, first, second and third guides, the first and second guides positioned on opposing sides of the first bin, and the second and third guides positioned on opposing sides of the second bin, a movable wall arranged generally perpendicular relative to the first, second and third guides, at least one sensor and a pusher, the movable wall and the first, second and third guides forming three sides of the first and second bins, the movable wall is translatable in a process direction, the method comprising:
a) determining a first process direction length of each of a portion of the plurality of media using the at least one sensor; and,
b) positioning the movable wall based on the first process direction length.

13. The method of claim 12 wherein the system further comprises a fixed wall arranged generally perpendicular relative to the first, second and third guides, the fixed wall, the movable wall and the first, second and third guides form four sides of the first and second bins, and the step of positioning the movable wall forms a distance between the fixed wall and the movable wall based on the first process direction length.

14. The method of claim 12 wherein the first and second bins each comprises a front portion, a rear portion and a gap separating the front portion and the rear portion, the gap of the first bin is aligned with the gap of the second bin.

15. The method of claim 14 wherein the movable wall is secured to the front portion of the first bin and the front portion of the second bin.

16. The method of claim 15 wherein at least one of a width of the gap of the first bin and a width of the gap of the second bin is changed during translation of the movable wall.

17. The method of claim 16 wherein the width of the gap of the first bin is less than the width of the gap of the second bin.

18. The method of claim 15 wherein the system further comprises a fixed wall arranged generally perpendicular relative to the first, second and third guides, the fixed wall, the movable wall and the first, second and third guides form four sides of the first and second bins, and a position of the pusher is maintained in a central location between the fixed wall and the movable wall during translation of the movable wall.

19. The method of claim 14 further comprising:
c) positioning the first, second and third guides in non-retracted locations;
d) depositing a first set of the plurality of media in the first bin and a second set of the plurality of media in the second bin;
e) positioning the first, second and third guides in retracted locations;
f) moving the first set with the pusher to the second bin vertically above the second set to form a first combined set; and,
g) moving the first combined set with the pusher to the collated stack receiver,
wherein the pusher moves in a cross process direction within the gap.

20. The method of claim 12 wherein the first and second bins form a continuous surface and the movable wall complimentarily aligns with the continuous surface.
