Abstract
A sheet manufacturing apparatus includes a defibrator configured to produce defibrated material, a feedstock supply unit, a monitoring device, and a cleaning device. The feedstock supply unit includes a conveyance device configured to convey feedstock, a storage device configured to accumulate the feedstock conveyed from the conveyance device and supply the feedstock to the defibrator, and a measuring device configured to measure a state of the feedstock accumulated on the storage device. The monitoring device is configured to predict stopping of conveyance of the feedstock by the feedstock supply unit and activate the cleaning device when a conveyance speed of the feedstock by the feedstock supply unit becomes slower than during normal operation. The cleaning device is configured to execute on at least one of the conveyance device and the storage device a cleaning process that preemptively prevents the stopping of conveyance.
