The same information or different information may be displayed on the first terminal device 400a and the second terminal device 400b, respectively.

[0020] The collection bag G can transportably store a plurality of pieces of paper C generated by the waste paper shredder 200. The collection bag G stores the amount of pieces of paper C measured by the mass sensor 229 provided in the waste paper shredder 200. The mass sensor 229 will be described later. The user of the waste paper shredder 200 may transfer the plurality of pieces of paper C generated by the waste paper shredder 200 from the storage box 223 to the collection bag G. The user of the waste paper shredder 200 may directly store the plurality of pieces of paper C in the collection bag G in the waste paper shredder 200 by attaching the collection bag G to the storage box 223. The collection bag G containing the plurality of pieces of paper C is transported by the carrier B.

[0021] The carrier B transports the collection bag G containing the plurality of pieces of paper C to the first company A1. The first company A1 owns the sheet manufacturing apparatus 100.

The first carrier B1 or the second carrier B2 may transport the collection bag G of the second company A2 and the collection bag G of the third company A3 to the first company A1. The transportation form of the collection bag G is set as appropriate.

[0023] FIG. 2 shows a schematic configuration of the sheet manufacturing apparatus 100. The sheet manufacturing apparatus 100 regenerates pieces of paper C such as waste paper into sheets in a dry method. The sheet manufacturing apparatus 100 is not limited to being dry and may be wet. Here, the dry method is a method of regenerating the sheet without performing the regeneration of the sheet P in a liquid and performing the regeneration of the sheet in the air such as the atmosphere.

[0024] Figure 2 shows coordinate axes orthogonal to each other as the X1 axis, Y1 axis, and Z1 axis, respectively. The direction pointed by the arrow corresponding to each axis is the + direction, and the direction opposite to the + direction is the - direction. The Z1 axis is a virtual axis along the vertical direction, where the +Z1 direction indicates upward and the -Z1 direction indicates downward. The -Z1 direction is the direction in which gravity acts. Inside the sheet manufacturing apparatus 100, the front in the conveyance direction of raw materials, web W, and sheet P, etc. may be indicated as downstream, and the front in the direction opposite to the conveyance direction may be indicated as upstream. For the sake of illustration, the sizes of each member are different from the actual ones.

[0025] The sheet manufacturing apparatus 100 includes a first unit group 101, a second unit group 102, and a third unit group 103. The first unit group 101, the second unit group 102, and the third unit group 103 are supported by a frame (not shown). Figure 2 shows the direction in which the piece of paper C, sheet P, slit piece S, and unnecessary end materials, etc. move with white arrows.

[0026] The sheet manufacturing apparatus 100 regenerates the sheet P from the piece of paper C. In the sheet manufacturing apparatus 100, when viewed from the side in the -X1 direction, the first unit group 101, the third unit group 103, and the second unit group 102 are arranged from the -Y1 direction toward the +Y1 direction.

[0027] The piece of paper C is conveyed from the first unit group 101 to the second unit group 102 through the first pipe 21 that crosses inside the third unit group 103. The piece of paper C is defibrated, etc. in the second unit group 102 to become fibers and then becomes a mixture containing a binder, etc. The mixture is conveyed to the third unit group 103 through the third pipe 24. The mixture is formed into the web W in the third unit group 103 and then formed into the belt-like sheet P. The belt-like sheet P is cut in the first unit group 101 to become the sheet P.

[0028] The first unit group 101 includes a buffer tank 13, a metering supply unit 15, a confluence unit 17, and a first pipe 21. In the first unit group 101, the buffer tank 13, the metering supply unit 15, the confluence unit 17, and the first pipe 21 are arranged in order from upstream to downstream. The first unit group 101 includes a first cutting unit 81, a second cutting unit 82, a tray 91, and a crushing unit 95. The first cutting unit 81 and the second cutting unit 82 cut the strip-shaped sheet P into a sheet P with a predetermined shape. The first unit group 101 further includes a water supply unit 67. The water supply unit 67 is configured as a water storage tank as an example. The water supply unit 67 supplies humidifying water to each of a first humidifying unit 65 and a second humidifying unit 66 described later through a water supply pipe (not shown).

[0029] The paper pieces C are put into the buffer tank 13 from the raw material inlet 11. The paper pieces C contain fibers such as cellulose and are, for example, shredded waste paper pieces. Humidified air is supplied into the buffer tank 13 from the second humidifying unit 66 provided in the third unit group 103.

[0030] The paper pieces C to be defibrated are temporarily stored in the buffer tank 13 and then conveyed to the metering supply unit 15 according to the operation of the sheet manufacturing apparatus 100. The sheet manufacturing apparatus 100 may be provided with a shredding mechanism for shredding the paper pieces C and the like upstream of the buffer tank 13.

[0031] The metering supply unit 15 includes a weighing device 15a and a supply mechanism (not shown). The weighing device 15a weighs the mass of the paper pieces C. The supply mechanism supplies the paper pieces C weighed by the weighing device 15a to the downstream confluence unit 17. The metering supply unit 15 weighs the paper pieces C to a predetermined mass by the weighing device 15a and supplies the paper pieces C of the predetermined mass to the downstream confluence unit 17 by the supply mechanism.

[0032] Digital and analog weighing mechanisms are applicable to the weighing device 15a. As the weighing device 15a, physical sensors such as load cells, spring scales, and balances are used. It is preferable that a load cell is used as the weighing device 15a. The predetermined mass at which the weighing device 15a weighs the paper pieces C is, for example, about several grams to several tens of grams.

[0033] Known technologies such as a vibratory feeder can be applied to the supply mechanism. The supply mechanism may be a configuration included in the meter 15a.

[0034] The weighing and supply of the paper pieces C in the metering supply unit 15 are batch processes. The supply of the paper pieces C from the metering supply unit 15 to the confluence unit 17 is carried out intermittently. The metering supply unit 15 may have a plurality of meters 15a. When the plurality of meters 15a operate with a predetermined time difference, the weighing efficiency is improved.

[0035] In the confluence unit 17, the shredded pieces of the slit pieces S supplied from the crushing unit 95 are confluent and mixed with the paper pieces C supplied from the metering supply unit 15. The slit pieces S and the crushing unit 95 will be described later. The paper pieces C mixed with the shredded pieces flow from the confluence unit 17 into the first pipe 21.

[0036] The first pipe 21 conveys the paper pieces C from the first unit group 101 to the second unit group 102 by an air flow generated by a blower (not shown).

[0037] The second unit group 102 includes a defibrating unit 31 which is a dry defibrator, a separating unit 32, a second pipe 23, a mixing unit 33, and a third pipe 24. In the second unit group 102, the defibrating unit 31, the separating unit 32, the second pipe 23, the mixing unit 33, and the third pipe 24 are arranged in order from upstream to downstream. The second unit group 102 has a fourth pipe 25 connected to the separating unit 32, a recovery unit 35, a compressor 38, and a power supply unit 39.

[0038] The paper pieces C conveyed through the first pipe 21 flow into the defibrating unit 31. The defibrating unit 31 dry-defibrates the paper pieces C supplied from the metering supply unit 15 into fibers. Known defibrating mechanisms can be applied to the defibrating unit 31.

[0039] The fiber disintegrating unit 31 includes, for example, a stator and a rotor. The stator has a substantially cylindrical inner surface. The rotor is installed inside the stator and rotates along the inner surface of the stator. The paper piece C is sandwiched between the inner surface of the stator and the rotor. The paper piece C is disintegrated by the shearing force generated between the inner surface of the stator and the rotor. In the fiber disintegrating unit 31, the entangled fibers contained in the paper piece C are unraveled. The fibers contained in the paper piece C are conveyed to the separating unit 32.

[0040] The separating unit 32 separates the disintegrated fibers. The separating unit 32 removes components unnecessary for the production of the sheet P from the fibers. The separating unit 32 separates the fibers into relatively long fibers and relatively short fibers. The relatively short fibers may cause a decrease in the strength of the sheet P. The separating unit 32 separates and removes the relatively short fibers. The separating unit 32 separates and removes colorants, additives, etc. contained in the paper piece C. Known techniques such as the disk mesh method can be applied to the separating unit 32.

[0041] Inside the separating unit 32, air humidified by the second humidifying unit 66 of the third unit group 103 is supplied.

[0042] The fibers from which relatively short fibers etc. have been removed are conveyed to the mixing unit 33 via the second pipe 23. Unnecessary components such as relatively short fibers and colorants are discharged to the recovery unit 35 via the fourth pipe 25.

[0043] The mixing unit 33 mixes a binder etc. with the fibers in the air to generate a mixture. The mixing unit 33 includes a flow path through which the fibers are conveyed, a fan, a hopper, a supply pipe, and a valve. The flow path, fan, hopper, supply pipe, and valve are not shown.

[0044] The hopper communicates with the flow path of the fibers via the supply pipe. The valve is provided in the supply pipe between the hopper and the flow path. The hopper supplies a binder such as starch into the flow path. The valve adjusts the mass of the binder supplied from the hopper to the flow path. The mixing ratio of the fibers and the binder is adjusted by the valve.

[0045] The mixing unit 33 may be configured to supply materials other than the binder. As an example, the mixing unit 33 is provided with a configuration for supplying a coloring material, an additive, or the like.

[0046] The fan of the mixing unit 33 generates an air flow. Due to the air flow generated by the fan, the mixing unit 33 mixes the binder and the like in the air while transporting the fibers downstream to generate a mixture. The mixture flows from the mixing unit 33 into the third pipe 24.

[0047] The recovery unit 35 includes a filter (not shown). The filter filters out unnecessary components such as relatively short fibers transported by the air flow in the fourth pipe 25.

[0048] The compressor 38 generates compressed air. In the filter of the recovery unit 35, clogging may occur due to fine particles or the like among the unnecessary components. It is possible to blow the compressed air generated by the compressor 38 onto the filter to blow off the attached particles and clean the filter.

[0049] The power supply unit 39 includes a power supply device that supplies power to each component of the sheet manufacturing apparatus 100. The power supply device is not shown. The power supply unit 39 distributes the power supplied from the outside to each component of the sheet manufacturing apparatus 100.

[0050] The third unit group 103 deposits and compresses a mixture containing fibers generated from the paper pieces C, and regenerates it into a belt-shaped sheet P that is recycled paper. The third unit group 103 includes a deposition unit 50, a first transport unit 61, a second transport unit 62, a first humidifying unit 65, a second humidifying unit 66, a drainage unit 68, a forming unit 70, and a cleaning device 40. The third unit group 103 corresponds to an example of a papermaking unit.

[0051] In the third unit group 103, the deposition unit 50, the first transport unit 61, the second transport unit 62, the first humidifying unit 65, the forming unit 70, and the cleaning device 40 are arranged in order from upstream to downstream. The second humidifying unit 66 is arranged below the first humidifying unit 65.

[0052] The depositing section 50 deposits a mixture containing the separated fibers in the air to generate a web W. The depositing section 50 includes a drum member 53, a blade member 55 installed inside the drum member 53, a housing 51 that houses the drum member 53, and a suction section 59. The mixture is taken into the inside of the drum member 53 from the third pipe 24.

[0053] Below the depositing section 50, a first conveying section 61 is arranged. The first conveying section 61 has a mesh belt 61a and five tensioning rollers that tension the mesh belt 61a. The suction section 59 faces the drum member 53 across the mesh belt 61a along the Z1 axis.

[0054] The blade member 55 is arranged inside the drum member 53. The blade member 55 is rotationally driven by a motor (not shown). The drum member 53 is a semi-cylindrical sieve. A net having the function of a sieve is provided on the lower surface of the drum member 53. The drum member 53 allows particles such as fibers and mixtures smaller than the mesh size of the sieve net to pass from the inside to the outside of the drum member 53.

[0055] The mixture is agitated by the blade member 55 rotating inside the drum member 53 and is discharged to the outside of the drum member 53. Humidified air from the second humidifying section 66 is supplied to the inside of the drum member 53.

[0056] The suction section 59 is arranged below the drum member 53. The suction section 59 sucks the air inside the housing 51 through a plurality of holes in the mesh belt 61a. The plurality of holes in the mesh belt 61a allow air to pass through but make it difficult for fibers, binders, etc. contained in the mixture to pass through. The mixture discharged to the outside of the drum member 53 is sucked downward together with the air. The suction section 59 is a known suction device such as a blower.

[0057] The mixture is dispersed in the air inside the housing 51 and deposited on the upper surface of the mesh belt 61a by gravity and the suction of the suction section 59. When the mixture is deposited on the upper surface of the mesh belt 61a, the web W is formed.

[0058] The mesh belt 61a is an endless belt. The mesh belt 61a is stretched by five stretching rollers. The mesh belt 61a rotates counterclockwise in a plan view from the -X1 direction due to the rotation of the stretching rollers. A mixture continuously accumulates on the mesh belt 61a, and the web W is formed. The web W contains a relatively large amount of air and is soft and swollen. The first conveying unit 61 conveys the formed web W downstream by the rotation of the mesh belt 61a.

[0059] The second conveying unit 62 conveys the web W downstream of the first conveying unit 61, replacing the first conveying unit 61. The second conveying unit 62 peels the web W from the upper surface of the mesh belt 61a. The second conveying unit 62 conveys the peeled web W toward the forming unit 70. The second conveying unit 62 is disposed upstream of the -Y1 direction end of the mesh belt 61a above the conveying path of the web W. The second conveying unit 62 and the mesh belt 61a are arranged to partially overlap along the Z1 axis.

[0060] The second conveying unit 62 has a transport belt (not shown), a plurality of rollers, and a suction mechanism. The transport belt is provided with a plurality of holes through which air passes. The transport belt is stretched by a plurality of rollers and rotates by the rotation of the rollers.

[0061] The second conveying unit 62 sucks the upper surface of the web W to the lower surface of the transport belt by the negative pressure generated by the suction mechanism. By rotating the transport belt while the web W is adsorbed, the web W is conveyed downstream.

[0062] The first humidifying unit 65 humidifies the web W containing fibers deposited in the deposition unit 50 of the third unit group 103. The first humidifying unit 65 is, for example, a mist-type humidifier. The first humidifying unit 65 supplies mist M from below to the web W conveyed by the second conveying unit 62 for humidification. The first humidifying unit 65 is disposed below the second conveying unit 62. The first humidifying unit 65 faces the web W conveyed by the second conveying unit 62. A known humidifying device such as an ultrasonic type can be applied to the first humidifying unit 65.

[0063] When the web W is humidified with the mist M, the function as a binder for starch is promoted. The strength of the sheet P is improved. Since the first humidifying unit 65 humidifies the web W from below, the droplets derived from the mist M are prevented from falling onto the web W. Since the first humidifying unit 65 humidifies the web W from the opposite side of the contact surface between the transport belt and the web W, the adhesion of the web W to the transport belt is reduced. The second conveying unit 62 conveys the web W to the forming unit 70.

[0064] The forming unit 70 forms the web W containing fibers into a belt-shaped sheet P by heating and pressing. The forming unit 70 has a first forming roller 71 and a second forming roller 72. Each of the first forming roller 71 and the second forming roller 72 incorporates an electric heater. Each of the first forming roller 71 and the second forming roller 72 can raise the temperature of the roller surface.

[0065] The first forming roller 71 and the second forming roller 72 are substantially columnar members. The rotation axes of the first forming roller 71 and the second forming roller 72 are arranged along the X1 axis. The first forming roller 71 is disposed above the conveyance path of the web W. The second forming roller 72 is disposed below the conveyance path of the web W. A gap corresponding to the thickness of the sheet P to be manufactured is provided between the first forming roller 71 and the second forming roller 72.

[0066] The first forming roller 71 and the second forming roller 72 are rotationally driven by a forming roller drive motor (not shown). The web W is sandwiched between the first forming roller 71 and the second forming roller 72 and is fed downstream while being heated and pressed. The web W continuously passes through the forming section 70 and is press-formed while being heated. By using the first forming roller 71 and the second forming roller 72, the heating and pressing of the web W are efficiently performed.
