Abstract

A cleaning apparatus includes a cleaning roller configured to rotate about a first rotation axis to clean a component to which paper dust is attached, the cleaning roller having a first area and a second area that is adjacent to the first area in a direction along the first rotation axis and to which more paper dust is attached than to the first area, and a remover configured to rotate about a second rotation axis extending in a direction different from the first rotation axis and configured to come in contact with at least a portion of the second area to remove the paper dust from the second area.

First claim

What is claimed is:

1. A fiber structure manufacturing apparatus, comprising:
an accumulation unit including a belt on which a fiber-containing material is accumulated to form an accumulation;
a forming unit disposed downstream relative to the accumulation unit in a transport direction of the accumulation, the forming unit including a pressure portion, the pressure portion applying a pressure to the accumulation to form a sheet-like object containing fiber; and
a cleaning apparatus disposed below the pressure portion, the cleaning apparatus including
a cleaning roller configured to rotate about a first rotation axis to clean the pressure portion to which paper dust is attached, the first rotation axis extending the first direction, the cleaning roller having a first area and a second area that is adjacent to the first area in the first direction and to which more paper dust is attached than to the first area, and
a remover configured to rotate about a second rotation axis, the second rotation axis extending in a second direction different from the first direction, the remover being configured to come in contact with at least a portion of the second area to remove the paper dust from the second area.

2. The fiber structure manufacturing apparatus according to claim 1 , wherein the pressure portion is further configured to transport the sheet-like object containing fiber, and
the second area corresponds to a position of an end portion in a direction intersecting a transportation direction of the sheet-like object.

3. The fiber structure manufacturing apparatus according to claim 2 , wherein the first area is located at a middle in a longitudinal direction of the cleaning roller and the second area is located at both first and second end portions in the longitudinal direction of the cleaning roller, the longitudinal direction is the first direction, and
the remover is defined by a first remover and a second remover, the first remover and the second remover being provided for the first and second end portions of the cleaning roller, respectively.

4. The fiber structure manufacturing apparatus according to claim 3 , wherein the first remover and the second remover are configured to rotate in opposite directions.

5. The fiber structure manufacturing apparatus according to claim 1 , further comprising:
a driver configured to rotate the remover; and
a controller electrically connected to the driver and configured to control the driver.

6. The fiber structure manufacturing apparatus according to claim 5 , wherein the controller is configured to control the driver to cause the remover to alternate rotation and suspension.

7. The fiber structure manufacturing apparatus according to claim 1 , wherein the remover has a plate-like shape.

8. The fiber structure manufacturing apparatus according to claim 1 , further comprising a cleaner that is disposed next to the remover in the second direction and is configured to clean the remover.

9. The fiber structure manufacturing apparatus according to claim 8 , wherein the cleaner includes a contact member that directly comes in contact with the remover to clean the remover.

10. The fiber structure manufacturing apparatus according to claim 8 , wherein the cleaner includes a vibrator that is coupled to the remover and is configured to vibrate the remover.

11. The fiber structure manufacturing apparatus according to claim 2 , wherein the cleaning roller is a brush roller.
