Abstract: A transport device includes a transport pipe for transporting a material to be transported having at least one of a sheet piece, a fiber, and a powder, and a blower for generating an air flow in the transport pipe, the transport device transports the material to be transported by the air flow, in which the transport pipe has an introduction port into which the material to be transported is introduced, the air flow has a velocity difference in a direction orthogonal to a direction of the air flow in the transport pipe, and the introduction port is provided on a side where a velocity of the air flow is lower.

Abstract: A defibration treatment apparatus including a feeding hole through which a material is fed, a rotator that rotates about a rotational central axis, a fixed member that covers at least a portion of the rotator, and a discharge opening that discharges a defibrated object obtained by defibrating the material between the rotator and the fixed member. In the defibration treatment apparatus, the rotator includes a plurality of rotary blades that extend in directions away from the rotational central axis, at least a portion of the fixed member is configured of a screen including a plurality of openings, the screen is disposed at a position corresponding to an outer rotational circumference of the rotator, and a discharge path in communication with the discharge opening is provided along the screen and on a side opposite the rotator with respect to the screen.

Abstract: A separation device includes a first ejection unit that ejects a material containing a fiber together with gas and supplies the material onto a first surface of the mesh, a first suction unit that sucks a part of the material supplied onto the first surface, a second ejection unit that ejects gas toward a second surface, and a second suction unit that sucks and collects, the material that does not pass through the mesh by the first suction unit and remains on the first surface. Q1<Q2 and Q3<Q4, where a flow rate of gas ejected from the first ejection unit is Q1, a flow rate of gas sucked by the first suction unit is Q2, a flow rate of gas ejected from the second ejection unit is Q3, and a flow rate of gas sucked by the second suction unit is Q4.

Abstract: A separation device includes a rotating member that has a mesh having a first surface and a second surface in a front and back relationship and a protruding member provided on the first surface side of the mesh, a supply unit that supplies a material containing a fiber onto the first surface of the mesh, a suction unit that is provided on the second surface side of the mesh and configured to suck a part of the material supplied onto the first surface, and a collection unit that collects the material deposited on the first surface.

Abstract: A separation device includes a separation unit that has a first ejection unit having a first ejection port for depositing a material containing a fiber on a first surface, and a first suction unit having a first suction port for sucking from the first surface toward a second surface so that at least a part thereof overlaps the first ejection port, a second suction unit provided at a position different from the first ejection port and having a second suction port for sucking from the second surface toward the first surface, a detection unit that detects information on foreign matter contained in the material ejected from the first ejection port, an input unit that inputs a detection result of the detection unit, and a control unit that controls a separation condition in the separation unit based on the information input to the input unit.

Abstract: A sheet manufacturing apparatus includes an impeller mill, a first sieve, a first belt, a rotary body, a second sieve, a second belt, and a heating roller. The impeller mill defibrates a raw material containing fiber and discharges a defibrated material. The first sieve screens the defibrated material by causing the defibrated material to pass through a first net. The defibrated material passing through the first sieve is deposited on the first belt to form a web. The rotary body has a protrusion radially protruded from a rotation center and divides the web by rotation to form a subdivided body. The second sieve refines the subdivided body by causing the subdivided body to pass through the second net to form a web. The refined subdivided body is deposited on the second belt to form a web. The heating roller heats the web from the second belt to form a sheet.
