Waste powder recovery device and image forming device
A waste powder recovery device includes: a recovery container that houses waste powder and has an inlet through which the waste powder is received; and a conveying component that is cantilever-supported in such a way as to swing freely inside the recovery container, the conveying component having a first conveying section with which the waste powder brought in through the inlet is conveyed with a first conveying force within the recovery container, and a second conveying section with which the waste powder is conveyed with a second conveying force that is larger than the first conveying force.
1. A waste powder recovery device comprising:
a recovery container that houses waste powder and has an inlet through which the waste powder is received; and
a conveying component that is cantilever-supported in such a way as to swing freely inside the recovery container, the conveying component having a first conveying section with which the waste powder brought in through the inlet is conveyed with a first conveying force within the recovery container, and a second conveying section with which the waste powder is conveyed with a second conveying force that is larger than the first conveying force.
2. The waste powder recovery device according to claim 1 ,
wherein the conveying component has a spiral blade, is rotationally driven, and thereby conveys the waste powder.
3. The waste powder recovery device according to claim 2 ,
wherein, in the first conveying section, a pitch of the spiral blade is wider than in the second conveying section.
4. The waste powder recovery device according to claim 3 ,
wherein the first conveying section is formed in a range including a position below the inlet from a cantilever-supported base end of the conveying component.
5. The waste powder recovery device according to claim 2 ,
wherein, in the first conveying section, a pitch of the spiral blade is two or more times wider than in the second conveying section.
6. The waste powder recovery device according to claim 2 ,
wherein the first conveying section is formed in a range including a position below the inlet from a cantilever-supported base end of the conveying component.
7. The waste powder recovery device according to claim 1 ,
wherein the first conveying section is formed in a range including a position below the inlet from a cantilever-supported base end of the conveying component.
8. The waste powder recovery device according to claim 1 ,
wherein the conveying component has a shaft body, and the spiral blade is formed integrally with the shaft body with a gap being maintained therebetween.
9. The waste powder recovery device according to claim 1 ,
wherein the conveying component is formed using a synthetic resin.
10. An image forming device comprising:
a first conveying component that conveys waste powder recovered from an image forming component that forms a toner image; and
a second conveying component that causes the waste powder to drop toward the waste powder recovery device according to claim 1 .
11. A waste powder recovery device comprising:
a recovery container that houses waste powder and has an inlet through which the waste powder is received; and
a conveying component that is cantilever-supported in such a way as to swing freely inside the recovery container, the conveying component having a first conveying section with which the received waste powder is conveyed with a first conveying force and piled up according to a first deposition profile within the recovery container, and a second conveying section with which the waste powder is conveyed with a second conveying force that is larger than the first conveying force and piled up according to a second deposition profile that is higher than the first deposition profile.
12. The waste powder recovery device according to claim 11 ,
wherein the conveying component has a spiral blade, is rotationally driven, and thereby conveys the waste powder.
13. The waste powder recovery device according to claim 12 ,
wherein, in the first conveying section, a pitch of the spiral blade is wider than in the second conveying section.
14. The waste powder recovery device according to claim 13 ,
wherein the first conveying section is formed in a range including a position below the inlet from a cantilever-supported base end of the conveying component.
15. The waste powder recovery device according to claim 12 ,
wherein, in the first conveying section, a pitch of the spiral blade is two or more times wider than in the second conveying section.
16. The waste powder recovery device according to claim 12 ,
wherein the first conveying section is formed in a range including a position below the inlet from a cantilever-supported base end of the conveying component.
17. The waste powder recovery device according to claim 11 ,
wherein the first conveying section is formed in a range including a position below the inlet from a cantilever-supported base end of the conveying component.
18. The waste powder recovery device according to claim 11 ,
wherein the conveying component has a shaft body, and the spiral blade is formed integrally with the shaft body with a gap being maintained therebetween.
19. The waste powder recovery device according to claim 11 ,
further comprising a detection component that detects whether or not the waste powder that has piled up according to the second deposition profile within the recovery container has reached a predetermined height.
20. The waste powder recovery device according to claim 15 ,
wherein the detection component is arranged at a height that is reached by the waste powder when the waste powder substantially fills the recovery container, and that is reached by the waste powder when the waste powder that has piled up according to the first deposition profile substantially reaches the inlet.
