Abstract

An impeller member, a cleaning apparatus utilizing the impeller member, and an electrostatographic reproducing machine utilizing the cleaning apparatus are provided for cleaning particulate material from the surface of a re-usable image retaining member and for transporting and storing the particulate material. The cleaning apparatus includes a cleaning device for removing the material from the surface of the image retaining member and a storage device for storing the material removed by the cleaning device. A transport device for transporting the material from the cleaning device to the storage device includes an impeller member having a first portion extending from an end thereof for moving the particulate material transversely of the storage device and a second portion of the member adjacent to the first portion for moving the material rearwardly into the storage device.

Claims

1. An impeller member for use in a reproduction machine for receiving particulate material from a source thereof at a first position, and for transporting said material into a receiving means at a second and different position, said impeller member having a first portion extending from an end thereof having means for moving said material transversely of said receiving means, said first portion comprising an auger which moves said material axially inwardly of said member, said member having a second portion adjacent said first portion, said second portion having means for moving said material into said receiving means, said second portion of said member comprising a paddle.

2. An apparatus as in claim 1 wherein said paddle has a square cross-section.

3. An apparatus for cleaning, transporting and storing particulate material from the surface of a reusable image retaining member including:

a cleaning means for removing said material from said surface;

storage means for storing said material removed by said cleaning means; and

transport means for transporting said material from said cleaning means to said storage means;

the improvement wherein, said transport means includes an impeller member having a first portion extending from an end thereof, having means for moving said material transversely of said storage means and a second portion of said member adjacent said first portion, said second portion having means for moving said material into said storage means.

4. An apparatus as in claim 3, further including a housing for supporting said cleaning means, said transport means and said storage means, said housing including a pair of spaced apart opposing said walls and wherein said first portion of said member comprises an auger which moves said material inwardly of the side walls of said housing.

5. An apparatus as in claim 4, wherein said second portion comprises a paddle.

6. An apparatus as in claim 5, wherein said storage means comprises a sump and further including flexible wall means cooperatively engaging said impeller member for retaining said particulate material in said sump.

7. An apparatus as in claim 6, wherein said sump has a configuration with uneven volume, wherein the sump volume is greater on a first side than on a second and opposing side of said sump, and wherein said auger portion is arranged to transport said material from said second side to said first side.

8. An apparatus as in claim 7, wherein said paddle has a square cross-section and wherein said member includes a cylindrical flange positioned at the transition between said auger portion and said paddle portion.

9. An apparatus as in claim 5, wherein the outside diameter of said auger portion is greater than the width of said square, and wherein said wall means comprises a unitary strip like member engaging both said auger and paddle portions of said member.

10. In an electrostatographic reproducing apparatus including an image retaining member;

means for forming an electrostatic image on a surface of said member;

means for developing said electrostatic image by the application of particulate material thereto;

means for transferring said developed image to a sheet of final support material; and

means for cleaning residual particulate material from said surface following transfer, said cleaning means including means for removing said material from said surface, storage means for storing said material removed by said cleaning means, and transport means for transporting said material from said cleaning means to said storage means;

the improvement wherein, said transport means includes an impeller member having a first portion extending from an end thereof having means for moving said material transversely of said storage means and a second portion of said member adjacent said first portion, said second portion having means for moving said material into said storage means.

11. An apparatus as in claim 10, further including a housing for supporting said cleaning means, said transport means and said storage means, said housing including a pair of spaced apart opposing side walls and wherein said first portion of said member comprises an auger which moves said material inwardly of the side walls of said housing.

12. An apparatus as in claim 11, wherein said second portion comprises a paddle.

13. An apparatus as in claim 12, wherein said storage means comprises a sump and further including flexible wall means cooperatively engaging said impeller member for retaining said particulate material in said sump.

14. An apparatus as in claim 13, wherein said sump has a configuration with uneven volume, wherein the sump volume is greater on a first side than on a second and opposing side of said sump, and wherein said auger portion is arranged to transport said material from said second side to said first side.

15. An apparatus as in claim 14, wherein said paddle has a square cross-section and wherein said member includes a cylindrical flange positioned at the transition between said auger portion and said paddle portion.

16. An apparatus as in claim 15, wherein the outside diameter of said auger portion is greater than the width of said square, and wherein said wall means comprises a unitary strip like member engaging both said auger and paddle portions of said member.
