Fiber structure manufacturing apparatus

A fiber structure manufacturing apparatus, comprising:

• a defibrated material supplying unit that supplies a defibrated material obtained by defibrating a material that contains fibers;
• a resin supplying unit that supplies resin fibers;
• a mixing unit that produces a mixture by mixing the defibrated material with the resin fibers;
• an accumulation unit that produces an accumulated material by causing the mixture to accumulate;
• a shape molding unit that produces a fiber structure by performing shape molding of the accumulated material;
• and
• a control unit that controls operation of the resin supplying unit, wherein
• the resin supplying unit includes
• a fragmenting unit that produces resin fiber fragments by performing fragmentation of a cotton-like lump of the resin fibers,
• a reservoir unit that stores the resin fiber fragments, and
• a measurement unit that measures a weight or volume of the resin fiber fragments discharged from the reservoir unit, and
• based on a measurement result of the measurement unit, the control unit adjusts an amount of discharging the resin fiber fragments from the reservoir unit.
