Abstract

A fiber material accumulating apparatus which includes a storage section including a porous screen, a supply section which supplies a material containing fibers to the storage section, and a rotating body which is provided inside the storage section and includes a blade which rotates to agitate the material, in which the blade includes an extending portion extending along a rotational axis of the rotating body, and an opening through which the material passes when the blade rotates.

First claim

What is claimed is:

1. A fiber material accumulating apparatus comprising:
a storage section which includes a porous screen;
a supply section which supplies a material containing fibers to the storage section;
a rotating body which is provided inside the storage section and includes a blade which rotates to agitate the material; and
a belt on which the material dispersed via the porous screen accumulates, wherein
the blade includes
an extending portion that includes a longest dimension of the blade extending parallel to a rotational axis of the rotating body,
a plurality of extending portions separated in a direction intersecting the rotational axis, the extending portions including the extending portion, and
an opening through which the material passes when the blade rotates, a gap between the extending portions functioning as the opening.

2. The fiber material accumulating apparatus according to claim 1 , wherein
the extending portions have a plate shape.

3. The fiber material accumulating apparatus according to claim 2 , wherein
the extending portions are disposed such that a thickness direction extends along a radial direction of the rotating body.

4. The fiber material accumulating apparatus according to claim 2 , wherein
the extending portions are disposed such that a thickness direction is oriented to intersect a radial direction of the rotating body.

5. The fiber material accumulating apparatus according to claim 1 , wherein
the extending portions have a round rod shape.

6. The fiber material accumulating apparatus according to claim 1 , wherein
the rotating body rotates in a state of being separated from the porous screen.

7. The fiber material accumulating apparatus according to claim 1 , wherein
the porous screen includes a portion having an arc shape in a cross-sectional view.

8. The fiber material accumulating apparatus according to claim 1 , further comprising:
a housing which covers a portion between the storage section and a belt and in which an opening is formed at a position facing the belt.

9. The fiber material accumulating apparatus according to claim 1 , wherein the belt is a mesh belt, and further comprising:
a suction section provided on a side of the mesh belt opposite to the storage section.

10. A sheet manufacturing apparatus comprising:
the fiber material accumulating apparatus according to claim 1 ; and
a shaping section which shapes accumulated matter formed by the fiber material accumulating apparatus into a sheet shape.
