Exit roll for an image forming device
View Patent ↗An exit roll for use in an image forming device. The exit roll may include a body and a kicker section each configured to mount to a shaft. The kicker section may include a plurality of fingers spaced around the periphery. Each of the fingers may include a first section that is substantially parallel to the shaft, and a second section that extends outward way from the shaft. The fingers may be flexible in an upwards and downwards direction into and away from the shaft. The exit roll is constructed to move media sheets out of the exit port and away from the image forming device.
1. A device to move a media sheet within an image forming device comprising:
a shaft;
a body mounted on the shaft and having an outer surface with a substantially constant radius;
a kicker section in contact with the body, the kicker section having a plurality of fingers each comprising a base that extends substantially axially away from the body, and an extension at a distal end of the base and extending substantially radially outward from the base;
each of the fingers being radially flexible between a first position that extends radially outward beyond the outer surface of the body, and a second position that is substantially at the same radial position away from the shaft as the outer surface of the body.
2. The device of claim 1 , wherein the body and the kicker section are a single piece.
3. The device of claim 1 , wherein the plurality of fingers are grouped in pairs with gaps separating each of the finger pairs.
4. The device of claim 3 , further comprising a void positioned within each of the finger pairs, the void extends through at least a portion of the base.
5. The device of claim 4 , wherein the void is positioned off-center within each of the finger pairs.
6. The device of claim 1 , wherein the extension forms an angle of about 90 degrees with the base.
7. The device of claim 1 , wherein the extension comprises first and second corners with the first corner having a greater height than the second corner.
8. The device of claim 1 , wherein a radius of the kicker section formed at the extension is less than the body.
9. The device of claim 8 , wherein a centerpoint of each of the plurality of fingers is positioned radially and angularly away from a body centerpoint.
10. A roll to move a media sheet along a media path within an image forming device comprising:
a plurality of fingers each having a first section extending substantially parallel to the media path, and a second section positioned along a peripheral edge of the first section and extending outward from the first section in a direction away from the media path;
each of the fingers having a continuous outer edge extending between a first edge and a second edge with the first edge having a greater height than the second edge.
11. The roll of claim 10 , wherein the second section extends substantially perpendicularly outward from the first section.
12. The roll of claim 10 , further comprising a body positioned proximate to the roll, the body having a substantially smooth exterior surface.
13. The roll of claim 12 , wherein each of the fingers is flexible between a first position with a diameter of the fingers being greater than the body, and a second position with the diameter of the fingers being substantially equal to the body.
14. The roll of claim 10 , wherein each of the fingers is grouped into pairs comprising a first finger and a second finger, a void is positioned between the first and second fingers.
15. The roll of claim 14 , further comprising a gap positioned between a first finger pair and a second finger pair, the gap being larger than the void.
16. A device for moving a media sheet within an image forming device comprising:
a shaft;
a body mounted on the shaft and having an outer surface with a substantially constant radius;
a kicker section in contact with the body, the kicker section having a plurality of paired fingers spaced about the periphery, each of the paired fingers comprising two bases that extend substantially axially away from the body, and two extensions at a distal end of the bases and extending substantially radially outward from the bases;
each of the paired fingers being radially flexible between a first position that extends radially outward beyond the outer surface of the body, and a second position that is substantially at a same radial position away from the shaft as the outer surface of the body.
17. The device of claim 16 , wherein a centerpoint of each finger is angularly and radially offset from a body centerpoint.
18. The device of claim 16 , wherein each of the extensions comprise a leading edge and a reverse edge, the leading edge having a greater height than the reverse edge.
19. The device of claim 16 , further comprising a void positioned within each of the paired fingers, the void extending through at least each of the two bases.
20. The device of claim 16 , further comprising a gap position between each of the paired finger, the gap extending a distance inward from a peripheral edge beyond the two extensions and through a majority of the two bases.
