Abstract

A fibrous material accumulating apparatus includes a dispersing section which disperses a material containing fibers, a belt which accumulates the dispersed material, and a suction section provided on a side of the belt opposite to the dispersing section, in which the dispersing section includes a storage section including a screen, a supply section which supplies the material to the storage section, and a rotating body which is provided inside the storage section and agitates the material supplied into the storage section, and the storage section includes a communicating port which causes an inside and an outside of the storage section to communicate with each other and is provided at a different position from the screen.

Claims (34)

1. A fibrous material accumulating apparatus comprising:

a dispersing section which disperses a material containing fibers;

a belt which accumulates the dispersed material; and

a suction section provided on a side of the belt opposite to the dispersing section, wherein

the dispersing section includes

a storage section including a screen,

a supply section which supplies the material to the storage section, and

a rotating body which is provided inside the storage section and agitates the material supplied into the storage section,

the storage section includes a plurality of communicating ports which causes an inside and an outside of the storage section to communicate with each other and is provided at a different position from the screen,

the plurality of communicating ports are aligned along an axis parallel to a rotational axis of the rotating body,

the plurality of communicating ports are located above the rotating body in a first direction, and

the plurality of communication ports are offset from the rotational axis on only one side of the rotational axis in a second direction perpendicular to the rotational axis and the first direction.

2. The fibrous material accumulating apparatus according to claim 1 , wherein

the plurality of communicating ports supplies air along a rotational direction of the rotating body.

3. The fibrous material accumulating apparatus according to claim 1 , wherein

air supplied from the plurality of communicating ports is introduced through suction of the suction section.

4. The fibrous material accumulating apparatus according to claim 1 , wherein

the plurality of communicating ports is provided on a more distal side than the supply section with respect to a rotational center of the rotating body in plan view of the dispersing section.

5. The fibrous material accumulating apparatus according to claim 1 , wherein

the supply section supplies the material along a rotational direction of the rotating body.

6. The fibrous material accumulating apparatus according to claim 1 , wherein

the screen has an arc shape which protrudes toward the belt side.

7. The fibrous material accumulating apparatus according to claim 1 , wherein

the rotating body rotates in a state of being separated from the screen.

8. The fibrous material accumulating apparatus according to claim 1 , wherein

the dispersing section includes a housing which covers a portion between the storage section and the belt and which includes an opening at a position facing the belt.

9. The fibrous material accumulating apparatus according to claim 1 , wherein

the storage section includes a holding member which holds the screen, and

the plurality of communicating ports is provided in the holding member.

10. The fibrous material accumulating apparatus according to claim 4 , wherein

an outlet of the supply section overlaps the rotating body in the plan view of the dispersing section.

11. A sheet manufacturing apparatus comprising:

the fibrous material accumulating apparatus according to claim 1 ; and

a shaping section which shapes a web formed by the fibrous material accumulating apparatus into a sheet shape.
