Abstract

A diverter assembly to transport a substrate along a transport path includes a plurality of sets of idle rollers and at least one support member. Each set of idle rollers may include a longitudinal axis and a plurality of respective idle rollers disposed along the respective longitudinal axis. Each idle roller of adjacent sets of idle rollers may be in a staggered arrangement with each other. The at least one roller support member may rotatably support the respective sets of idle rollers. The plurality of sets of idle rollers may be in a circumferential arrangement with each other.

First claim

What is claimed is:

1. A diverter assembly to transport a substrate along a transport path usable with an image forming system, the diverter assembly comprising:
at least three rows of idle rollers disposed on a circumference around a reference longitudinal axis, the at least three rows of idle rollers comprising:
a first set of idle rollers disposed along a first longitudinal axis and spaced apart from each other;
a second set of idle rollers disposed along a second longitudinal axis and spaced apart from each other; and
a third set of idle rollers disposed along a third longitudinal axis and spaced apart from each other;

wherein the rollers of the second set of idle rollers are in a staggered arrangement with respective idle rollers of the first set of idle rollers and the third set of idle rollers such that rollers in adjacent sets overlap with each other in a direction around the circumference; and
at least one roller support member to rotatably support the first, second, and third set of idle rollers; and
wherein the substrate travels along the transport path outside the circumference around which are arranged the first, second, and third sets of idle rollers.

2. The diverter assembly according to claim 1 , further comprising:
a fifth set of idle rollers disposed along a fifth longitudinal axis and spaced apart from each other; and
a fourth set of idle rollers disposed along a fourth longitudinal axis and spaced apart from each other, each one of the fourth set of idle rollers are in a staggered and circumferentially overlapping arrangement with each one of the respective idle rollers of the third set of idle rollers and the fifth set of idle rollers; and
wherein the first, second, third, fourth and fifth sets of idle rollers are in a circumferential arrangement with each other and are supported by the at least one roller support member.

3. The diverter assembly of claim 2 , wherein the staggered arrangement of the first, second, third, fourth and fifth sets comprises a quincunx staggered arrangement.

4. The diverter assembly according to claim 1 , wherein each one of the first, second, and third sets of idle rollers includes at least three idle rollers.

5. The diverter assembly according to claim 4 , wherein each one of the first, second, and third sets of idle rollers includes five idle rollers.

6. The diverter assembly according to claim 1 , wherein the each one of the idle rollers of the first, second, and third sets of idle rollers is substantially a same size.

7. The diverter assembly according to claim 6 , wherein a distance of space between adjacent idle rollers along a corresponding longitudinal axis is smaller than a longitudinal length of the respective adjacent idle rollers.

8. The diverter assembly according to claim 1 , wherein each one of the idle rollers comprises plastic.

9. An image forming system, comprising:
a main support member;
a fluid applicator unit to form an image on a substrate; and
at least one diverter assembly to transport a substrate along a transport path, comprising:
a plurality of sets of idle rollers, each set of idle rollers having a longitudinal axis and a plurality of respective idle rollers disposed along the respective longitudinal axis, the sets of idle rollers being disposed on a circumference around a reference longitudinal axis;
each idle roller of adjacent sets of idle rollers is in a staggered arrangement with each other such that rollers in adjacent sets overlap with each other in a direction around the circumference; and
at least one roller support member to rotatably support the respective sets of idle rollers and to couple a respective idle roller to the main support member; and
wherein the substrate travels along the transport path outside the circumference along the outer surface of the circumferentially arranged plurality of sets of idle rollers.

10. The image forming system according to claim 9 , wherein the plurality of sets of idle rollers includes at least three sets of idle rollers.

11. The image forming system according to claim 10 , wherein the plurality of sets of idle rollers includes five sets of idle rollers.

12. The image forming system according to claim 9 , wherein each one of the plurality of sets of idle rollers includes at least three idle rollers.

13. The image forming system according to claim 12 , wherein each one of the plurality of sets of idle rollers includes five idle rollers.

14. The image forming system according to claim 9 , wherein each one of the idle rollers of the plurality of idle rollers is substantially a same size.

15. The diverter assembly of claim 9 , wherein the staggered arrangement of the plurality of sets of idle rollers comprises a quincunx staggered arrangement.

16. The image forming system according to claim 9 , wherein a distance of space between adjacent idle rollers along a corresponding longitudinal axis is smaller than a longitudinal length of the respective adjacent idle rollers.

17. The image forming system according to claim 9 , wherein the at least one roller support member of the plurality of sets of roller support members further comprises sheet metal and each one of the idle rollers includes plastic.

18. The image forming system according to claim 9 , wherein each one of the idle rollers includes tapered ends.

19. The image forming system according to claim 9 , wherein the at least one diverter assembly includes a plurality of diverter assemblies.

20. A diverter assembly to transport a substrate along a transport path usable with an image forming system, the diverter assembly comprising:
a first set of idle rollers disposed along a first longitudinal axis and spaced apart from each other;
a second set of idle rollers disposed along a second longitudinal axis and spaced apart from each other;
a third set of idle rollers disposed along a third longitudinal axis and spaced apart from each other;
a fourth set of idle rollers disposed along a fourth longitudinal axis and spaced apart from each other;
a fifth set of idle rollers disposed along a fifth longitudinal axis and spaced apart from each other, wherein the five sets of idle rollers are disposed on a circumference around a reference longitudinal axis and rollers in adjacent sets are staggered so as to overlap with each other in a direction around the circumference; and
at least one roller support member to rotatably support the first, second, third, fourth and fifth sets of idle rollers; and
wherein the first, second, third, fourth and fifth sets of idle rollers are in a circumferential arrangement with each other equidistant from the reference longitudinal axis wherein the substrate travels along the transport path outside the circumference on which are arranged the sets of idle rollers, and
wherein a distance of space between adjacent idle rollers along a corresponding longitudinal axis is smaller than a longitudinal length of the respective adjacent idle rollers, and
wherein the staggered arrangement of the first, second, third, fourth and fifth sets of idle rollers comprises a quincunx staggered arrangement.
