There is provided a dispersion device including: a supply section having a supply pipe for supplying a material containing fibers together with air, and a chamber that has a first swirl flow forming portion forming a first swirl flow of the air containing the material and a second swirl flow forming portion communicating with the first swirl flow forming portion and forming a second swirl flow in a direction opposite to the first swirl flow of the air containing the material and that is coupled to the supply pipe; a dispersion section that has a casing formed with a discharge port for discharging the material, stirs the material in the casing, and discharges and disperses the material from the discharge port into air; and a coupling section having a communication port through which the first swirl flow forming portion and the second swirl flow forming portion communicate with the casing.

Dispersion device and accumulation device

A fibrous body accumulating device includes an accumulating section including a drum that introduces and releases a material including fibers, a detection section detecting a presence of the material in the drum, and an estimation section estimating an amount of the material in the drum based on a detection frequency at which the detection section detects the material. The fibrous body accumulating device further includes a storage section in which a calibration curve showing a relationship between the detection frequency and the amount of the material in the drum is stored, and the estimation section calculates information on the detection frequency and estimates the amount of the material in the drum with reference to the calibration curve.
