Abstract
A sheet manufacturing apparatus that shortens the time until the apparatus stops is provided. The sheet manufacturing apparatus has a sieve unit having at least part of material defibrated in a defibration process introduced thereto, moving at a first speed, and passing defibrated material through multiple openings disposed in the main section thereof; and a forming unit forming a sheet using precipitate that past through the openings of the sieve unit; the sheet manufacturing apparatus stopping the sieve unit with defibrated material that was introduced stored inside the sieve unit when production by the sheet manufacturing apparatus stops.
Claims4
A sheet manufacturing apparatus comprising:
- a sieve unit which has at least part of material defibrated in a defibration process introduced thereto, and includes a plurality of openings through which the defibrated material passes and which are disposed in the main section of the sieve unit;
- a belt on which precipitate that has passed through the openings of the sieve unit is deposited to form a sheet;
- a defibrator that performs the defibration process to defibrate the material and is arranged upstream relative to the sieve unit in a conveyance direction of the material;
- and
- a control unit including a CPU and a memory, and configured to control the sieve unit and the belt, the control unit being configured to move the sieve unit at a first speed, wherein
- the control unit
- receives from the memory an instruction on stop of manufacturing the sheet at the sheet manufacturing apparatus, and
- based on the instruction, controls the sieve unit to stop movement of the sieve unit with defibrated material that was introduced stored inside the sieve unit and the defibrator to stop defibration of the material after controlling the sieve unit to stop the movement of the sieve unit.
