Problems solved by technology

[0004] However, in the stacking device of Patent Document 1, fibers in the drum are not sufficiently dismantled, and there is a possibility of clumping.
In this case, unevenness may occur in the fibers ejected from each ejection hole.
As a result, many clusters are mixed in the deposit, or the thickness is uneven, which leads to a decrease in the quality of the deposit.

Abstract

The invention provides a fiber body stacking device and a fiber structure manufacturing device capable of obtaining high-quality deposits. The fiber body stacking device includes: a drum having an opening for releasing a material containing fibers and rotating around a central axis; and a first dispersion member disposed in the drum and at a position unevenly distributed vertically below the central axis, and dispersing the material in the drum. Preferably, the fibrous body stacking device further includes a second dispersion member disposed in the drum and at a position unevenly distributed vertically above the central axis, and dispersing the material in the drum.

Description

technical field [0001] The present invention relates to a fiber body stacking device and a fiber structure manufacturing device. Background technique [0002] In recent years, a sheet manufacturing apparatus realized by a dry method using as little water as possible has been proposed. Regarding the sheet manufacturing apparatus, for example, a stacking device that discharges and deposits a fibrous body, and a method of pressurizing the stack formed by the stacking device to form a sheet are known. As this stacking device, for example, a device having such a configuration as disclosed in Patent Document 1 can be cited. [0003] The stacking device described in Patent Document 1 includes a rotating drum having discharge holes, and a supply unit that supplies fibers into the drum. As the drum rotates, the fibers in the drum are released from the discharge holes and accumulated below. [0004] However, in the stacking device of Patent Document 1, the fibers in the drum are no...
