Abstract
A sheet manufacturing apparatus 1 includes a quantitative feeder unit 15 that measures a predetermined amount of a raw material C and feeds the measured raw material C, a defibration unit 31 that defibrates the raw material C fed from the quantitative feeder unit 15 into fibers, a third unit group 103 that deposits and compresses the fibers and forms the fibers into a sheet, a first frame F1 to which the quantitative feeder unit 15 is fixed, and a second frame F2 that is separated from the first frame F1 and to which the defibration unit 31 is fixed.
Claims2
A sheet manufacturing apparatus for manufacturing a sheet comprising:
- a quantitative feeder unit including
- a physical sensor or a balance that measures a predetermined amount of a raw material and
- a vibratory feeder that feeds the measured raw material;
- a defibration unit that includes a stator and a rotor and that defibrates the raw material fed from the quantitative feeder unit;
- a separator that separates fibers from the defibrated raw material by removing constituents that are not required to manufacture the sheet;
- a filter that filters out the constituents;
- a compressor that generates compressed air and cleans the filter by blowing the compressed air to the filter;
- a sheet forming unit including a belt on which the fibers are deposited and a pair of rollers that compresses the fibers that have been deposited to form the fibers into a sheet;
- a first frame to which the quantitative feeder unit is fixed;
- and
- a second frame that is separated from the first frame, to which the defibration unit is fixed, and in which the separator, the filter, and the compressor are installed.
