Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The embodiments described below do not limit the contents of the present invention described in the claims. Moreover, not all of the configurations described below are essential constituent requirements of the present invention.

(First Embodiment)
FIG. 1 is a diagram showing a configuration of a sheet manufacturing system 1 according to the first embodiment.
In the sheet manufacturing system 1 described in the present embodiment, for example, used waste paper (sheet) such as confidential paper as a raw material is defibrated by a dry method to be fiberized, and then pressurized, heated, and cut. It is a suitable device for producing new paper. By mixing various additives with the fibrous raw material, it is possible to improve the bond strength and whiteness of paper products and add functions such as color, scent, and flame retardancy according to the application. May be good. In addition, by controlling the density, thickness, and shape of the paper and molding it, it is possible to manufacture paper of various thicknesses and sizes according to the application, such as A4 and A3 office paper and business card paper.

The sheet manufacturing system 1 includes a first device 100A and a second device 100B. The first device 100A and the second device 100B are separate devices and can operate independently of each other.
The first apparatus 100A is an apparatus (also referred to as a coarse crushing / defibration apparatus or a defibration apparatus) for producing defibrated fibers by coarsely crushing and defibrating used paper as a raw material. It has a coarse crushing unit 12, a defibration unit 20, a sorting unit 30, and a fiber processing unit 40. The second device 100B is a device for manufacturing a sheet using defibrated fibers as a raw material (also referred to as a sheet manufacturing device or a sheet manufacturing section), and is a fiber supply section 45, an additive mixing section 50, a deposition section 60, and a sheet forming section. It has a 70 and a cutting portion 90.

The supply unit 10 supplies the raw material to the coarse crushing unit 12. The raw material may be any material containing fibers, and examples thereof include paper, pulp, pulp sheets, cloths containing non-woven fabrics, and woven fabrics. In this embodiment, a configuration using used paper as a raw material is illustrated. The supply unit 10 is, for example, an automatic loading unit having a tray (paper feed tray) on which used paper is placed and continuously feeding the used paper placed on the tray into the coarse crushing unit 12.

The crushed portion 12 (shredded portion) coarsely crushes (shreds) the raw material supplied by the supply unit 10 with the crushing blade 14 into coarsely crushed pieces (hereinafter referred to as coarsely crushed products). The crushed product is in the same state as a shredder piece shredded with a so-called shredder. The coarse crushing blade 14 is a blade for coarsely crushing a raw material in the air (in the air) or the like. The crushing unit 12 includes a pair of crushing blades 14 for coarsely crushing the raw material, and a driving unit for rotating the crushing blade 14, and can have the same configuration as a so-called shredder. The shape and size of the coarsely crushed pieces are arbitrary, and may be suitable for the defibration treatment in the defibration portion 20. For example, the crushing unit 12 coarsely crushes the raw material into pieces of paper having a size of 1 to several cm square or less.
The raw material coarsely crushed by the crushing section 12 is received by the hopper 1 and then transferred (conveyed) to the defibrating section 20 via the pipe 2.

The defibration section 20 defibrate the coarsely crushed product crushed by the coarse crushing section 12. More specifically, the defibration section 20 defibrate the raw material (crude product) coarsely crushed by the defibration section 12 to produce defibrated fibers. Here, "defibrating" means unraveling a raw material (defibrated material) formed by binding a plurality of fibers into individual fibers. The defibration unit 20 also has a function of separating substances such as resin particles, ink, toner, and bleeding inhibitor adhering to the raw material from the fibers.

A product that has passed through the defibration section 20 is called a "defibration product". In addition to the defibrated fibers that have been unraveled, the "defibrated product" includes resin grains (resin for binding multiple fibers) separated from the fibers when the fibers are unraveled, ink, toner, etc. It may also contain additives such as colorants, anti-bleeding agents, and paper strength enhancers. The shape of the unraveled defibrated fiber is a string shape or a ribbon shape. The unraveled defibrated fibers may exist in an unentangled state (independent state) with other unraveled defibrated fibers, or may be entangled with other unraveled defibrated fibers to form a lump. It may exist in a state where it has become (a state in which a so-called "dama" is formed).

The defibration section 20 performs defibration in a dry manner. Here, performing a process such as defibration in the air (in the air) or the like, not in a liquid, is referred to as a dry method. In the present embodiment, the defibration section 20 uses an impeller mill. Specifically, the defibration unit 20 includes a rotor that rotates at high speed (not shown) and a liner (not shown) located on the outer periphery of the rotor. The coarsely crushed pieces crushed by the crushed portion 12 are sandwiched between the rotor and the liner of the defibrating portion 20 and defibrated.

The defibration unit 20 generates an air flow by rotating the rotor. Due to this air flow, the defibrating section 20 sucks the coarse crushed pieces as a raw material from the introduction port 22 of the pipe 2 and conveys the defibrated product to the discharge port 24. The defibrated product is sent out from the discharge port 24 to the pipe 3 and transferred to the sorting unit 30 via the pipe 3. As the airflow for transporting the defibrated product from the defibration unit 20 to the sorting unit 30, the airflow generated by the defibration unit 20 may be used, or an airflow generator such as a blower is provided to provide the airflow. You may use it.

The sorting unit 30 has an introduction port 32 into which a defibrated product containing defibrated fibers defibrated by the defibrating unit 20 flows from the tube 3 together with the air flow. The sorting unit 30 sorts the defibrated products to be introduced into the introduction port 32 according to the length of the fibers. Specifically, the sorting unit 30 sorts the defibrated products having a size smaller than or equal to a predetermined size as the first sorted product and the defibrated products larger than the first sorted product as the second sorted product. .. The first selection contains small particles and the like in addition to the defibrated fibers, and the second selection includes, for example, large fibers, undefibrated pieces (coarse crushed pieces that are not sufficiently defibrated), and defibrated fibers. Includes lumps and the like that are aggregated or entangled.

In the present embodiment, the sorting unit 30 has a drum unit 31 (sieve unit), a housing unit 33 (covering unit) for accommodating the drum unit 31, and a first web forming unit 35. The drum portion 31 is a cylindrical sieve that is rotationally driven by a motor. The drum portion 31 has a net (filter, screen) and functions as a sieve (sieve). According to the mesh, the drum portion 31 selects a first sorter having a size smaller than the mesh opening (opening) of the mesh and a second sorter having a size larger than the mesh opening (opening) of the mesh. The net of the drum portion 31 is, for example, a wire mesh, an expanded metal obtained by stretching a metal plate having a cut, or a punching metal in which a hole is formed in the metal plate by a press machine or the like.

The defibrated product introduced into the introduction port 32 is sent into the inside of the drum portion 31 together with the air flow, and the first sorted product falls downward from the mesh of the drum portion 31 due to the rotation of the drum portion 31. The second sorting material that cannot pass through the mesh of the drum portion 31 is flowed by the air flow flowing into the drum portion 31 from the introduction port 32, guided to the discharge port 34, and sent out to the pipe 8.
The pipe 8 connects the inside of the drum portion 31 and the pipe 2. The second sort product flowing through the pipe 8 is supplied to the pipe 2 together with the coarsely crushed pieces coarsely crushed by the crushing unit 12, and is guided to the introduction port 22 of the defibration unit 20. As a result, the second sorted product is returned to the defibration section 20 and defibrated.

Further, the first sorted product sorted by the drum portion 31 is dispersed in the air through the mesh of the drum portion 31, and is attached to the mesh belt 36 of the first web forming portion 35 located below the drum portion 31. Descent towards.

The first web forming portion 35 (separation portion) includes a mesh belt 36 (separation belt), a roller 37, and a suction portion 38 (suction mechanism). The mesh belt 36 is an endless belt, which is suspended on three rollers 37, and is conveyed in the direction indicated by the arrow in the drawing by the rotation of each roller 37. The surface of the mesh belt 36 is composed of a net in which openings of a predetermined size are lined up. Of the first sorted material that descends from the sorting unit 30, fine particles of a size that passes through the mesh fall below the mesh belt 36, and fibers (defibration fibers) of a size that cannot pass through the mesh are the mesh belt 36. It is deposited on the mesh belt 36 and transported in the direction of the arrow together with the mesh belt 36. The fine particles falling from the mesh belt 36 include relatively small and low-density defibrated products (resin particles, coloring agents, additives, etc.), and are removed by the sheet manufacturing system 1 not used for sheet manufacturing. It is a thing.

The mesh belt 36 moves at a constant speed V1 during the normal operation of the first device 100A. Here, the term “normal operation” means that the first device 100A is in operation except when it is started and when it is stopped. Therefore, the defibrated product that has been defibrated by the defibrating section 20 is sorted into a first sorted product and a second sorted product by the sorting section 30, and the second sorted product is sorted through the tube 4 through the defibrating section 20. Returned to. In addition, the removed product is removed from the first sorted product by the first web forming unit 35. The rest after removing the removed material from the first sort is defibrated fibers suitable for producing a sheet, and the defibrated fibers are deposited on the mesh belt 36 to form the first web W1.

The suction unit 38 sucks air from below the mesh belt 36. The suction force of the suction unit 38 promotes the formation of the first web W1 on the mesh belt 36, and the removed material is quickly removed.

In the first device 100A, the configuration for sorting and separating the first defibrated product and the second defibrated product is not limited to the sorting unit 30 including the drum unit 41. For example, a configuration may be adopted in which the defibrated product processed by the defibrating unit 20 is classified by a classifier. As the classifying machine, for example, a cyclone classifying machine, an elbow jet classing machine, and an eddy classifier can be used. By using these classifiers, it is possible to sort and separate the first sort and the second sort. Further, the above-mentioned classifier can realize a configuration in which the debris containing relatively small or low-density defibrated products (resin particles, coloring agents, additives, etc.) is separated and removed.

The first device 100A includes a rotating body 39 that divides the first web W1 deposited on the mesh belt 36. The first web W1 is separated from the mesh belt 36 at a position where the mesh belt 36 is folded back by the roller 37, and is separated by the rotating body 39.

The configuration of the rotating body 39 is arbitrary, but in the present embodiment, it can have a rotating blade shape having plate-shaped blades and rotating. The rotating body 39 is arranged at a position where the first web W1 peeling from the mesh belt 36 and the blade come into contact with each other. Due to the rotation of the rotating body 39 (for example, the rotation in the direction indicated by the arrow R in the drawing), the blades collide with the first web W1 that is separated from the mesh belt 36 and conveyed, and the blades are divided and subdivided.
The rotating body 39 is installed at a position where the blades of the rotating body 39 do not collide with the mesh belt 36. For example, the distance between the tip of the blade of the rotating body 39 and the mesh belt 36 can be set to 0.05 mm or more and 0.5 mm or less. In this case, the rotating body 39 does not damage the mesh belt 36. 1 Web W1 can be divided efficiently.

The first web W1 divided by the rotating body 39 is supplied to the fiber processing unit 40 through the pipe 7. The fiber processing unit 40 is a device that makes the defibrated fiber into a portable form by performing a process of accommodating the first web W1 made of the defibrated fiber in the cartridge 200 (container). For example, a filling device for filling the cartridge 200 with defibrated fibers by an air blowing method, or a press-fitting device for press-fitting (filling) the defibrated fibers into the cartridge 200 with a conveyor such as a screw is applied to the fiber processing unit 40. be able to.
In this way, the first device 100A is a coarse crushing device for coarsely crushing used paper as a raw material containing fibers, a defibrating device for defibrating the coarse crushed material, and a fiber processing device for accommodating the defibrated fibers in the cartridge 200. It is configured as a device that is integrally equipped with. Hereinafter, for convenience of explanation, when the first device 100A is functionally described, it is appropriately described as "coarse crushing / defibration device".

The cartridge 200 is a container that can hold the defibrated fibers filled inside without flowing out, and can be easily carried by the user. The cartridge 200 may be a rigid metal container or a resin container, or a flexible container such as a bag.

The fiber processing unit 40 has a discharge unit 42 that allows the cartridge 200 containing the defibrated fibers to be freely taken out from the outside and discharged. Thereby, the user can easily take out the cartridge 200 and carry it to the second device 100B. The user is a person who uses the sheet manufacturing system 1, and may be a person who uses only a part of the functions of the sheet manufacturing system 1. For example, the user is a person who is at the installation location of the first device 100A (a person who works in an office described later, etc.), a person who operates, maintains, manages, etc. Workers, etc.

In this configuration, since the defibrated fibers are housed in the cartridge 200, the defibrated fibers can be carried while preventing the defibrated fibers from scattering and suppressing the mixing of foreign substances. Further, the filling rate of the defibrated fiber in the cartridge 200 can be easily increased by setting the pressure or the negative pressure when the defibrated fiber is stored (filled) in the cartridge 200. The pressure in this case is set to a value that does not hinder the production of the sheet in the second device 100B, and is set to a value at which the defibrated fiber can be taken out by the fiber supply unit 45 described later, for example.

The fiber processing unit 40 may be an apparatus (vacuum packing apparatus) for accommodating (filling) the defibrated fibers in the bag body by using the vacuum packing technique. In the case of vacuum packing, the filling rate of defibrated fibers can be further increased.
The fiber processing unit 40 is not limited to a device for accommodating the defibrated fiber in a container such as a cartridge 200 or a bag, and may be a device for processing the defibrated fiber in a state having shape retention. Specifically, a compression processing device that compresses the defibrated fiber into a plate shape by a roller or the like may be applied to the fiber processing unit 40, or the defibrated fiber may be formed into a rectangular parallelepiped shape, a spherical shape, or the like depending on a mold or the like. A compression molding apparatus for compression molding into a predetermined three-dimensional shape may be applied.

When the defibrated fibers are hardened into a plate shape, they can be easily stacked and moved together. Further, by solidifying the defibrated fibers into a predetermined three-dimensional shape such as a rectangular shape or a spherical shape, it becomes easy to put them in a storage case such as a box, which also makes it easy to move them together. In this case, by making the shape and size easy for the user to grasp by hand, it becomes easy to carry the defibrated fiber and to supply the second device 100B to the supply port 46. Since the cartridge 200 is not used, the configuration related to the cartridge 200 becomes unnecessary, and the configuration can be easily simplified. It should be noted that the defibrated fibers may be hardened to such an extent that they have shape retention, and the method is not limited to the method of uniformly hardening the whole, and only a part (for example, only the outer peripheral portion) may be hardened. In addition, water may be added to facilitate hardening.

In the second device 100B, the fiber supply unit 45 has a supply port 46 to which the defibrated fibers in a portable form are supplied. When the defibrated fiber is housed in the cartridge 200, the supply port 46 is configured to detach the cartridge 200. The fiber supply unit 45 takes out the portable defibrated fiber from the cartridge 200 set in the supply port 46 and discharges it to the pipe 8.
For example, a device for discharging the defibrated fibers in the cartridge 200 by blowing air or suction, or a device for scraping out the defibrated fibers in the cartridge 200 can be applied to the fiber supply unit 45. Further, a device may be applied to the fiber supply unit 45 by opening the lower part of the cartridge 200 and taking out the defibrated fiber by using gravity.

The fiber supply unit 45 preferably has a configuration in which the portable defibrated fiber is subdivided so that the additive mixing unit 50 can easily mix the additives. For example, when the fiber supply unit 45 scrapes out the defibrated fibers in the cartridge 200, it is preferable that the defibrated fibers are divided and subdivided by scraping. Further, when the fiber supply unit 45 discharges the defibrated fibers in the cartridge 200 by blowing air or suction, the defibrated fibers can be subdivided by the air flow.

Further, when the fiber processing unit 40 hardens the defibrated fibers to the extent that they have shape retention without using the cartridge 200, the hardened defibrated fibers (portable defibrated fibers) are supplied to the supply port 46. Is thrown into. In this case, the fiber supply unit 45 loosens the hardened defibrated fibers, and then uses, for example, ventilation or suction, scrapes out the introduced defibrated fibers, transports the belt, or uses gravity. The defibrated fibers can be discharged into the tube 8 by doing so.

The defibrated fiber discharged into the tube 8 is supplied to the additive mixing section 50. The additive mixing unit 50 generates an air flow in the pipe 8 for flowing the defibrated fibers discharged from the fiber supply unit 45 and the additive supply unit 52 for supplying the additive containing the resin to the additive mixing unit 50. A mixed blower 56 is provided.
In the additive mixing unit 50, an air flow is generated by the mixing blower 56, and the defibrated fiber and the additive are conveyed while being mixed in the pipe 8 and the pipe 9 connected to the downstream of the mixing blower 56. Further, the defibrated fibers are further loosened in the process of flowing through the tubes 8 and 9, and become finer fibrous.

The additive supply unit 52 (resin storage unit) is connected to an additive cartridge (not shown) that stores additives, and supplies the additives inside the additive cartridge to the pipe 8. The additive cartridge may have a structure that can be attached to and detached from the additive supply unit 52. Further, the additive cartridge may be provided with a configuration for replenishing the additive. The additive supply unit 52 is, for example, a device that temporarily stores an additive composed of fine particles or fine particles inside an additive cartridge, and supplies the stored additive to the pipe 8 using a screw feeder or the like.

The additive supplied by the additive supply unit 52 contains a resin such as a binder for binding a plurality of fibers. The resin contained in the additive is a thermoplastic resin or a thermosetting resin, for example, AS resin, ABS resin, polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylic resin, polyester resin, polyethylene terephthalate, polyphenylene ether, poly. Butylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like. These resins may be used alone or in admixture. That is, the additive may contain a single substance, may be a mixture, and may contain a plurality of types of particles each composed of a single substance or a plurality of substances. Further, the additive may be in the form of fibers or in the form of powder.
The resin contained in the additive melts by heating and binds a plurality of fibers to each other. Therefore, in a state where the resin is mixed with the fibers and not heated to a temperature at which the resin melts, the fibers are not bound to each other.

Further, the additive supplied by the additive supply unit 52 is, in addition to the binder, a colorant for coloring the fiber depending on the type of the sheet to be manufactured, and for suppressing the aggregation of the fiber and the aggregation of the resin. It may contain a coagulation inhibitor, a flame retardant for making fibers and the like hard to burn. In addition, the additive that does not contain a colorant may be colorless, or may be light in color so that it can be regarded as colorless, or may be white.

The mechanism for mixing the defibrated fiber and the additive is not particularly limited, and may be agitated by blades rotating at high speed, or may utilize the rotation of the container like a V-type mixer. These mechanisms may be installed before or after the mixing blower 56.

The depositing portion 60 deposits the defibrated product defibrated by the defibrating portion 20. More specifically, the depositing portion 60 introduces the mixture that has passed through the additive mixing portion 50 from the introduction port 62, loosens the entangled defibrated products (defibrated fibers), and causes the mixture to fall while being dispersed in the air. Further, when the resin of the additive supplied from the additive supply unit 52 is fibrous, the deposition unit 60 loosens the entangled resin. As a result, the depositing portion 60 can uniformly deposit the mixture on the sheet forming portion 70.

The stacking portion 60 has a drum portion 61 (drum) and a housing portion 63 (covering portion) for accommodating the drum portion 61. The drum portion 61 is a cylindrical sieve that is rotationally driven by a motor. The drum portion 61 has a net (filter, screen) and functions as a sieve (sieve). Through this mesh, the drum portion 61 allows fibers and particles having a smaller mesh opening (opening) to pass through and is lowered from the drum portion 61. The configuration of the drum portion 61 is, for example, the same as the configuration of the drum portion 31.

The "sieve" of the drum portion 61 may not have a function of selecting a specific object. That is, the "sieve" used as the drum portion 61 means that the drum portion 61 is provided with a net, and the drum portion 61 may drop all of the mixture introduced into the drum portion 61.

The sheet forming portion 70 has a second web forming portion 71, a pressing portion 82, and a heating portion 84. The second web forming portion 71 is arranged below the drum portion 61 and deposits the passing material that has passed through the depositing part 60 to form the second web W2 (deposit). The second web forming portion 71 has a mesh belt 72 (belt), a roller 74, and a suction mechanism 76.

The mesh belt 72 is an endless belt, which is suspended on a plurality of rollers 74 and is conveyed in the direction indicated by the arrow in the drawing by the rotation of the rollers 74. The mesh belt 72 is made of, for example, metal, resin, cloth, non-woven fabric, or the like. The surface of the mesh belt 72 is composed of a net in which openings of a predetermined size are lined up. Of the fibers and particles falling from the drum portion 61, fine particles of a size that passes through the mesh fall below the mesh belt 72, and fibers of a size that cannot pass through the mesh are deposited on the mesh belt 72, and the mesh belt It is conveyed in the direction of the arrow together with 72. The mesh belt 72 moves at a constant speed V2 during the operation of manufacturing the sheet.

The mesh of the mesh belt 72 is fine and can be sized so that most of the fibers and particles falling from the drum portion 61 do not pass through.
The suction mechanism 76 is provided below the mesh belt 72 (on the side opposite to the deposition portion 60 side). The suction mechanism 76 can generate a downward airflow (airflow from the deposit portion 60 toward the mesh belt 72) by the suction force of the suction blower (not shown).

The suction mechanism 76 sucks the mixture dispersed in the air by the deposit 60 onto the mesh belt 72. As a result, the formation of the second web W2 on the mesh belt 72 can be promoted, and the discharge rate from the deposition portion 60 can be increased. Further, the suction mechanism 76 can form a downflow in the fall path of the mixture, and can prevent the defibrate and additives from being entangled during the fall.

As described above, the second web W2 in a soft and swollen state containing a large amount of air is formed by passing through the deposition portion 60 and the second web forming portion 71 (web forming step). The second web W2 deposited on the mesh belt 72 is conveyed to the sheet forming portion 70.
In the transport path of the mesh belt 72, air containing mist is supplied to the downstream side of the depositing portion 60 by the humidifying portion 78. As a result, the mist generated by the humidifying portion 78 is supplied to the second web W2, and the amount of water contained in the second web W2 is adjusted. As a result, it is possible to suppress the adsorption of fibers to the mesh belt 72 due to static electricity.

The sheet forming portion 70 forms the sheet S by pressurizing and heating the second web W2 deposited on the mesh belt 72 and conveyed by the conveying portion 79 by the pressing portion 82 and the heating portion 84. By applying heat to the fibers of the defibrated product contained in the second web W2 and the additive, a plurality of fibers in the mixture are bound to each other via the additive (resin).
The pressurizing unit 82 is composed of a pair of calendar rollers 85, and pressurizes the second web W2 by sandwiching it with a predetermined nip pressure. When the second web W2 is pressurized, its thickness is reduced and the density of the second web W2 is increased. One of the pair of calendar rollers 85 is a drive roller driven by a pressurizing unit drive motor (not shown), and the other is a driven roller. The calendar roller 85 conveys the second web W2, which has become dense due to pressurization, toward the heating unit 84.

The heating unit 84 can be configured by using, for example, a heating roller (heater roller), a heat press molding machine, a hot plate, a hot air blower, an infrared heater, and a flash fuser. In the present embodiment, the heating unit 84 includes a pair of heating rollers 86. The heating roller 86 is heated to a preset temperature by a heater installed inside or outside. The heating roller 86 applies heat across the second web W2 pressurized by the calendar roller 85 to form a sheet represented by reference numeral S in FIG.
In this way, the second web W2 formed by the depositing portion 60 is pressurized and heated by the sheet forming portion 70 to become the sheet S.

One of the pair of heating rollers 86 is a drive roller driven by a heating unit drive motor (not shown), and the other is a driven roller. The heating roller 86 conveys the heated sheet S toward the cutting portion 90.
The number of calendar rollers 85 included in the pressurizing unit 82 and the number of heating rollers 86 included in the heating unit 84 are not particularly limited.

The cutting portion 90 (cutter portion) cuts the sheet S formed by the sheet forming portion 70. In the present embodiment, the cutting portion 90 cuts the first cutting portion 92 that cuts the sheet S in the direction intersecting the conveying direction of the sheet S indicated by the reference numeral F in the drawing, and the sheet S in the direction parallel to the conveying direction F. It has a second cutting portion 94 to be formed. The second cutting portion 94 cuts, for example, the sheet S that has passed through the first cutting portion 92.

The cut portion 90 forms a sheet S of a predetermined size such as A4 size. The cut sheet S of a single sheet is discharged to the discharge unit 96. The discharge unit 96 includes a paper discharge tray for discharging sheets S of a predetermined size, or a stacker for accumulating the sheets S.
In this way, the second device 100B is a fiber supply device that supplies the defibrated fibers in the cartridge 200, that is, a portable defibrated fiber, and a sheet that manufactures the sheet S using the defibrated fibers. It is configured as an apparatus integrally equipped with a manufacturing apparatus (sheet manufacturing unit). Hereinafter, for convenience of explanation, when the second device 100B is functionally described, it is appropriately described as "seat manufacturing device".

FIG. 2 is a block diagram showing a configuration including a control system of the sheet manufacturing system 1.

The control device 101A is a computer system composed of a main processor, a ROM, a RAM, and the like. In the control device 101A, each part (supply part 10, coarse crushing part 12, defibration part 20, sorting part 30, and press-fitting) of the first device 100A is executed by the main processor executing a basic control program stored in the ROM. Unit 40) is controlled. The operation unit 102A inputs various instructions to the first device 100A. The operation unit 103A has, for example, an operation switch or a touch panel.

The control device 101A can control each part of the first device 100A after the power of the first device 100A is turned on and the start-up sequence is executed. In this case, the control device 101A sets the production start instruction of the first web W1 (defibration fiber), the production conditions (production amount of the first web W1 and the like), the production start date and time (schedule), and the like via the operation unit 102A. Can accept input. Then, the control device 101A operates each part of the first device 100A when a manufacturing instruction is input or when a preset manufacturing start date and time is reached. As a result, the used paper can be roughly crushed and defibrated to produce the first web W1, and the cartridge 200 filled with the first web W1 can be discharged.

The display unit 103A displays various information related to the first device 100A under the control of the control device 101A. The display unit 103A is, for example, a liquid crystal display device. The remaining amount sensor 104A detects the remaining amount of the raw material (waste paper) in the first device 100A, and outputs the detection result to the control device 101A. The remaining amount sensor 104A is not limited to one, and may be plural. The remaining amount sensor 104A of the present configuration includes at least a sensor that detects the remaining amount of used paper in the supply unit 10.

When the control device 101A detects that the remaining amount of the used paper (raw material) remaining in the supply unit 10 has fallen below the set value by the remaining amount sensor 104A, the control device 101A performs a notification process for notifying the shortage of the used paper. The notification process includes display on the display unit 103A, audio output by an audio output unit (not shown), and the like. When the first device 100A is connected to an external device (for example, a PC (personal computer) operated by a user) via a communication network, there is a shortage of used paper in the external device (to the supply unit 10). Replenishment of used paper) may be notified.

Further, the remaining amount sensor for detecting the remaining amount of the coarsely crushed material in the coarsely crushed portion 12 may be further provided. In this case, when the control device 101A detects that the remaining amount of the coarsely crushed material has fallen below the set value by the remaining amount sensor 104A, the supply unit 10 supplies the used paper to the coarsely crushed part 12, and the coarsely crushed part It may be coarsely crushed to 12. By always securing the crushed product, the crushed product can be immediately supplied to the defibration unit 20 at the start of production of the first web W1, and the first web W1 can be produced quickly.

Further, the control device 101A records the operation history of the first device 100A in a memory (not shown), and performs a measurement process for measuring the amount of recycled paper processed, which indicates the amount of fiber processed, based on the operation history. The operation history is, for example, information in which the amount of used paper supplied by the supply unit 10 (number of sheets supplied) is associated with the date and time of supply. Further, in this configuration, the control device 101A counts the amount of used paper supplied (number of sheets supplied) by the supply unit 10 based on the operation history, and records this counted value as the amount of used paper processed in a memory (not shown).

The measurement process is not limited to this method, and a method capable of measuring the amount of recycled paper processed can be widely applied. For example, using a sensor that measures flow rate, weight, distance, etc., the amount of defibrated fibers defibrated by the defibrating section 20, the amount of crushed material crushed by the crushing section 12, the first web W1 The production amount of the waste paper or the amount of fibers filled in the cartridge 200 may be measured, and the measurement result may be used as the waste paper processing amount. Further, the number (number of times) of the cartridges 200 discharged by the first device 100A may be counted, and the counting result may be used as the amount of used paper processed. The control device 101A can notify the user and the like of the amount of used paper processed by displaying the amount of used paper processed on the display unit 103A.

As shown in FIG. 2, the second device 100B also has the control device 101B, the operation unit 102B, the display unit 103B, and the remaining amount sensor 104B in the same manner as the first device 100A, and controls the control device 101B. Below, it can operate independently.
The control device 101B is a computer system composed of a main processor, a ROM, a RAM, and the like. In the control device 101B, by executing the basic control program stored in the ROM by the main processor, each part of the second device 100B (fiber supply part 45, additive mixing part 50, deposit part 60, sheet forming part 70, And the cutting part 90) are controlled. The operation unit 102B inputs various instructions to the second device 100B. The operation unit 103B has, for example, an operation switch or a touch panel.

The control device 101B can control each part of the second device 100B after the power of the second device 100B is turned on and the start-up sequence is executed. In this case, the control device 101B is instructed to start manufacturing the sheet S, manufacturing conditions (density (basis weight), shape (size, thickness), color, manufacturing quantity (number of manufactured sheets) of the sheet S) via the operation unit 102B. Etc.), production start date and time (schedule), etc. can be accepted. Then, the control device 101B manufactures the sheet S by operating each part of the second device 100B when a manufacturing instruction is input or when a preset manufacturing start date and time is reached.

Here, the control device 101B adjusts the density of the sheet S by, for example, adjusting the speed V2 of the mesh belt 72 of the sheet forming portion 70 and adjusting the amount of fibers lowered from the drum portion 61. Control. Further, the control device 101B controls the color of the sheet S by controlling the type and amount of the colorant added by the additive supply unit 52 (FIG. 1). Further, the control device 101B controls the size of the sheet S by the cutting portion 90, and controls the thickness of the sheet S by the pressurizing portion 82. As a result, the sheet S is manufactured according to the preset manufacturing conditions.

The display unit 103B displays various information related to the second device 100B under the control of the control device. The display unit 103B is, for example, a liquid crystal display device. The remaining amount sensor 104B detects the remaining amount of the raw material in the second device 100B and / or the remaining amount of the manufactured sheet S, and outputs the detection result to the control device 101B. The remaining amount sensor 104B of this configuration is a remaining amount sensor that detects the remaining amount of the first web W1 (defibrated fiber) in the cartridge 200 mounted on the fiber supply unit 45 (hereinafter referred to as the remaining amount of the cartridge 200). At least has.

When the control device 101B detects that the remaining amount of the cartridge 200 has fallen below the set value by the remaining amount sensor 104B, the control device 101B performs a notification process for notifying the shortage of the remaining amount of the cartridge 200. The notification process includes display on the display unit 103B, audio output by an audio output unit (not shown), and the like. When the second device 100B is connected to an external device via a communication network, the external device may be notified of the shortage of fibers (raw materials) (replacement of the cartridge 200).

Further, the remaining amount sensor for detecting the remaining amount of the sheet S remaining in the discharge unit 96 may be further provided. In this case, when the control device 101B detects that the remaining amount of the sheet S remaining in the discharge unit 96 is less than the set value by the remaining amount sensor, the control device 101B performs a notification process for notifying the shortage of the sheet S. May be good. This notification process may be any of display, voice output, and notification to an external device, as described above.

Further, the control device 101B records the operation history of the second device 100B in a memory (not shown), and performs a measurement process for measuring the sheet production amount indicating the fiber processing amount based on the operation history. The operation history is, for example, information in which the number of sheets S manufactured and the date and time of manufacture are associated with each other. Further, in this configuration, the control device 101B counts the manufactured amount (manufactured number of sheets) of the sheet S based on the operation history, and records this counted value as the sheet manufactured amount in a memory (not shown). The control device 101B can notify the user and the like of the sheet production amount by displaying the sheet production amount on the display unit 103A. Instead of the method of measuring the number of sheets to be manufactured, the amount of fibers taken out from the cartridge 200 or the amount of the second web W2 to be manufactured may be measured.

As described above, since the first device 100A and the second device 100B can operate independently, it is not necessary to arrange them in the same place. Further, the first device 100A and the second device 100B are configured by a dry type that does not require a large-scale water facility. As a result, water-related equipment can be unnecessary or simplified as compared with the case where the raw material containing the fiber is put into water and the fiber is dissociated and re-made by a wet method (wet papermaking method, etc.). The degree of freedom is high.
For example, the second device 100B, which is a sheet manufacturing device, can be placed in an office where there is a demand for the sheet S, and the first device 100A, which is a coarse crushing / defibrating device, can be placed in the backyard (FIG. 2). This arrangement is referred to as an arrangement pattern A.

The office is an area where office work is mainly performed, and the backyard is an area where office work is not mainly performed, for example, a warehouse or a work place. An office is an area in which a relatively large number of machines require a sheet S, such as a relatively large number of printing devices that can use the sheet S as a printing medium.

In the case of the arrangement pattern A, the user brings the used paper generated in the office or the like to the backyard and sets it in the supply unit 10 of the first device 100A. Next, the user operates the first device 100A to coarsely crush and defibrate the used paper to produce the first web W1, and discharge the cartridge 200 filled with the first web W1. For example, the user can immediately make the confidential paper unreadable by setting the confidential document to be disposed of (hereinafter referred to as confidential paper) in the first device 100A and operating the device 100A.
In this way, the user can dispose of the used paper in the backyard and procure the defibrated fiber which is the raw material of the sheet S. In addition, it is possible to avoid the situation where vibration and noise due to coarse crushing and defibration are generated in the office.

The user then moves to the office with the cartridge 200 and sets the cartridge 200 in the fiber supply section 45 of the second device 100B. Then, by operating the second device 100B, the user can manufacture the sheet S from the first web W1 in the cartridge 200 as a raw material.
After that, the user can start printing on the sheet S by setting the manufactured sheet S in a printing device (not shown) in the office. That is, the sheet S required for printing can be manufactured on demand. If there is a manufactured sheet S in the discharge unit 96 of the second device 100B, if the sheet S is set in the printing device, the user can use the sheet S without waiting for the sheet S to be manufactured. Printing is possible using the sheet S.
This makes it possible to recycle used paper generated in offices and the like, and to dispose of confidential paper.

In the arrangement pattern A, since the second device 100B, which is a sheet manufacturing device, is arranged in the office, which is an area where the sheet S is used, the user can easily use the sheet S. Further, since the first device 100A for coarse crushing and defibration is arranged in the backyard, vibration and noise associated with coarse crushing and defibration are a problem as compared with the case where the first device 100A is arranged in the office. It doesn't become. In addition, since used paper such as confidential paper is only moved between the office and the backyard, it is advantageous in preventing leakage of confidential paper as compared with the case of requesting an external recycler to dispose of the used paper.
Therefore, the arrangement pattern A makes it possible to procure the manufactured sheet S in the office, and it is possible to avoid a situation in which vibration or noise due to coarse crushing, defibration, or the like is generated in the office.

The backyard as a place for arranging the sheet manufacturing system 1 may be a part of the office. For example, an area where the number of printing devices is relatively small or no printing device is present, or an area where the number of people who use the sheet S is relatively small can be widely applied. For example, when the office space constituting one room of a building is divided into a plurality of areas, the first device 100A is arranged in the area where the demand for the seat S is relatively high in each area, and the seat S is relatively located. The second device 100B may be arranged in an area where the demand is low.

Further, the arrangement is not limited to the arrangement pattern A, and an arrangement other than the arrangement pattern A is also possible. FIG. 3 is a diagram showing an example of a plurality of arrangement patterns.
In the arrangement pattern B shown in FIG. 3, the first device 100A and the second device 100B are arranged in the office. In this case, the user coarsely crushes and defibrates used paper such as confidential paper by the first device 100A arranged in the office. Therefore, the confidential paper can be made unreadable without being taken out of the office, which is advantageous in preventing the leakage of confidential paper. Further, when the seat S is required, the user can manufacture the seat S on demand by the second device 100B without moving from the office.

For example, the user stores the cartridge 200 discharged from the first device 100A, and when the defibrated fiber which is the raw material of the second device 100B becomes insufficient, the stored cartridge 200 is stored in the second device 200. Set in device 100B. As a result, the recycling of used paper can be completed only in the office.
Further, since the first device 100A and the second device 100B operate independently of each other, the devices 100A and 100B can be arranged at different places in the office. For example, in the office, the first device 100A can be arranged at a place away from the user, and the second device 100B can be arranged at a place close to the user or the printing device. In this case, the vibration and noise caused by the first device 100A are less likely to affect the user, and the user can procure the sheet S from the nearby second device 100B.

As described above, the arrangement pattern B is advantageous when the manufactured sheet S can be procured in the office while giving priority to the prevention of leakage of confidential information. The arrangement pattern B is arranged when the noise and vibration are reduced to the extent that the first device 100A can be used in the office, or when there is a place in the office where vibration and noise are unlikely to be a problem. Is suitable for.

In the arrangement pattern C shown in FIG. 3, the first device 100A is arranged in the office and the second device 100B is arranged in the backyard. In this case, as in the arrangement pattern B, the user can make the confidential paper unreadable without taking it out of the office, which is advantageous in preventing the leakage of the confidential paper. Further, the cartridge 200 containing the defibrated fiber obtained by the first device 100A is carried to the backyard by the user.

Then, the user moves to the backyard when manufacturing the sheet S and procures the cartridge 200 containing the defibrated fiber. The user can then set the defibrated fibers in a second device 100B located in the backyard and activate the second device 100B to produce the sheet S.
As described above, the arrangement pattern C is suitable for cases such as suppressing reduction of office space and effective use of the backyard while giving priority to prevention of leakage of confidential information.

As described above, the sheet manufacturing system 1 utilizes a defibrating section 20, a fiber processing section 40 that makes the defibrated fibers defibrated by the defibrating section 20 into a portable form, and a portable defibrated fiber. A second device 100B (sheet manufacturing unit) for manufacturing the sheet S is provided. Since the defibrated defibrated fibers are made portable, the second device 100B can be separated from the defibrated portion 20 and the fiber processing portion 40. Therefore, the second device 100B and / or the defibration section 20 and the like can be easily arranged in an office or the like where used paper as a material is generated and there is a demand for the manufactured sheet.

For example, if the vibration or noise caused by defibration is large enough to cause a problem in the office, only the second device 100B should be placed in the office to prevent the vibration or noise caused by defibration from occurring in the office. Can be done. Further, when the vibration and noise due to defibration are relatively small, the second device 100B is arranged in the office, and the defibration unit 20 is arranged in the office where vibration and noise are less likely to be a problem. It is possible to deal with it.

Further, since the fiber processing unit 40 accommodates the defibrated fiber in a container such as a cartridge 200 or a bag body, the defibrated fiber can be easily handled and the defibrated fiber can be easily carried.
Further, when the fiber processing unit 40 processes the defibrated fiber into a state having shape retention, a container such as a cartridge 200 becomes unnecessary, and the apparatus configuration can be easily simplified. In this case, by treating the defibrated fibers into any of a plate shape, a rectangular parallelepiped shape, and a spherical shape, effects such as facilitating the movement of the defibrated fibers together can be expected. When the defibrated fibers are stored in a container such as a cartridge 200 or a bag, the defibrated fibers may be processed into any of a plate shape, a rectangular parallelepiped shape, and a spherical shape. In this case, effects such as easy insertion into the cartridge 200 can be expected. Further, the shape of the container may be any of a plate shape, a rectangular parallelepiped shape, and a spherical shape.

Further, when the fiber processing unit 40 vacuum-packs the defibrated fibers into a portable form, the filling rate of the defibrated fibers can be efficiently increased and the defibrated fibers can be easily handled. .. Here, since the defibration section 20 is a dry type, it is not necessary to provide a water supply / drainage facility for defibration. Further, since water is not used, the process of accommodating the defibrated fibers in a container such as a cartridge 200 or vacuum-packing the defibrated fibers is easier than in the case where the defibrated portion is wet.

The mode in which the defibrated fiber is made portable is not limited to the above-mentioned form. For example, a binder for binding fibers may be contained in the defibrated fiber and then supplied to the fiber processing unit 40 so that the defibrated fiber in the portable form contains the binder. This eliminates the need to prepare a binder in the second device 100B. Further, the portable defibrated fiber may contain a material other than the binder, for example, a colorant, an agglutination inhibitor, a flame retardant, or the like. For example, a part or all of the structure of the additive supply unit 52 can be provided on the upstream side of the fiber processing unit 40 (that is, the side of the first device 100A).

Further, since the sheet manufacturing system 1 is composed of a first device 100A having a defibration section 20 and a second device 100B for manufacturing the sheet S, the second device 100B is arranged in an office or the like. , The first device 100A can be arranged in a place where vibration and noise due to defibration do not matter.
Moreover, since the first device 100A and the second device 100B can operate independently, the degree of freedom in their arrangement and operation is improved, and the sheet can be manufactured on demand.

In this case, the control device 111C can receive inputs such as a production start instruction of the coarse crushed product, a production condition (production amount of the crushed product, etc.), a production start date and time (schedule), and the like via the operation unit 112C. Then, when the production instruction is input or the production start date and time reached the preset production start date and time, the control device 111C operates each part of the third device 110C to coarsely crush the used paper, and the crushed material is produced. The filled cartridge 210 is ejected.

You may.

Further, the control device 111C records the operation history of the third device 110C in a memory (not shown), and performs a measurement process for measuring the amount of recycled paper processed, which indicates the amount of fiber processed, based on the operation history. The operation history is, for example, information in which the amount of used paper supplied by the supply unit 10 (number of sheets supplied) is associated with the date and time of supply. Further, in this configuration, the control device 111A counts the amount of used paper supplied (number of sheets supplied) by the supply unit 10 based on the operation history, and records this counted value as the amount of used paper processed in a memory (not shown). The measurement process is not limited to this method, and a method capable of measuring the amount of recycled paper processed can be widely applied.

The coarse crushed material supply unit 45A has a supply port 46A to which the cartridge 210 can be attached and detached, and takes out the crushed material from the cartridge 210 set in the supply port 46A and supplies it to the defibration unit 20. The defibration section 20, the sorting section 30, and the fiber processing section 40 are the same as those of the first apparatus 100A of the first embodiment. Hereinafter, for convenience of explanation, when the first device 110A is functionally described, it is appropriately described as "defibration device".

Further, the first device 110A has a control device 111A, an operation unit 112A, a display unit 113A, and a remaining amount sensor 114A, and can operate independently under the control of the control device 111A. The control device 111A is a computer system composed of a main processor, a ROM, a RAM, and the like. The control device 111A executes each part (crude material supply part 45A, defibration part 20, sorting part 30, fiber processing part 40) of the first device 110A by executing the basic control program stored in the ROM by the main processor. To control. The operation unit 112A inputs various instructions to the first device 110A.

In this case, the control device 111A sets the production start instruction of the first web W1 (defibration fiber), the production conditions (the production amount of the first web W1 and the like), the production start date and time (schedule), and the like via the operation unit 112A. Can accept input. Then, the control device 111A operates each part of the first device 110A when a manufacturing instruction is input or when a preset manufacturing start date and time is reached. As a result, the used paper can be defibrated to produce the first web W1, and the cartridge 200 filled with the first web W1 can be discharged.

The display unit 113A displays various information related to the first device 110A under the control of the control device 111A. The remaining amount sensor 114A detects the remaining amount of the fiber as a raw material in the first device 110A, and outputs the detection result to the control device 111A. The remaining amount sensor 114A detects, for example, the remaining amount of the crushed material in the cartridge 210 mounted on the crushed material supply unit 45A.

When the control device 111A detects that the remaining amount of the coarse crushed material in the first device 110A is less than the set value by the remaining amount sensor 114A, the control device 111A notifies the shortage of the crushed material (for example, replacement of the cartridge 210). I do. The notification process includes display on the display unit 113A, audio output by an audio output unit (not shown), and the like. When the first device 110A is connected to an external device (for example, a PC operated by a user) via a communication network, the external device may be notified of the shortage of coarse crushed material.

Further, the control device 111A records the operation history of the first device 110A in a memory (not shown), and performs a measurement process for measuring the amount of recycled paper processed, which indicates the amount of fiber processed, based on the operation history. The operation history is, for example, information in which the amount of defibrated fibers defibrated by the defibrating unit 20 is associated with the date and time of defibration. Further, in this configuration, the control device 111A counts the amount of defibrated fibers based on the operation history, and records the counted value as the amount of used paper processed in a memory (not shown). The amount of defibrated fibers can be measured by using, for example, a sensor that measures the flow rate, weight, distance, etc., and the production amount of the first web W1 or the amount of fibers filled in the cartridge 200 is solved. It may be measured as the amount of fiber fibers (waste paper processing amount). The control device 111A can notify the user and the like of the used paper processing amount by displaying the used paper processing amount on the display unit 113A.

The second device 100B is the same as that of the first embodiment.
In the present embodiment, since the first device 110A, the second device 100B, and the third device 110C constituting the sheet manufacturing system 1 can operate independently, it is not necessary to arrange them in the same place. Further, since each of the devices 110A, 100 and 110C is configured by a dry type that does not require a large-scale water facility, water-related equipment can be unnecessary or simplified as compared with the case of a wet configuration, and an office or the like can be used. Easy to install in.
For example, the second device 100B, which is a sheet manufacturing device, is arranged in an office where there is a demand for the sheet S, and the third device 110C, which is a coarse crushing device, is also arranged in an office where used paper to be crushed is generated. NS. In addition, the first device 110A, which is a defibrating device, is arranged in the backyard (FIG. 4). This arrangement is referred to as an arrangement pattern D.

In the case of the arrangement pattern D, the user can coarsely crush the used paper such as confidential paper by the third device 110C arranged in the office. Therefore, the confidential paper can be made unreadable without being taken out of the office, which is advantageous in preventing the leakage of confidential paper. Further, the crushed product obtained by the third device 110C is carried to the backyard by a user or the like.
As a result, the user can procure the cartridge 210) containing the coarsely crushed material in the backyard, and obtain the cartridge 200 containing the defibrated fiber by the second device 110B arranged in the backyard. In this case, since the defibration is performed in the backyard, the situation where vibration and noise due to the defibration are generated in the office is avoided.

The user can then move to the office with the cartridge 200 containing the defibrated fibers obtained in the backyard and have the sheet S manufactured by the second device 100B located in the office. By setting the manufactured sheet S in the printing device in the office, the user can immediately start printing on the sheet S.

In the arrangement pattern D, used paper such as confidential paper is roughly crushed in the office, which is advantageous in preventing leakage of confidentiality, and since the sheet S is manufactured in the office, the sheet S can be easily manufactured on demand. It becomes easy to use the sheet S for printing. In addition, since the defibration is performed in the backyard, it is possible to avoid the situation where vibration and noise due to the defibration are generated in the office.
In general, since dry defibration uses an impeller mill or the like, vibration and noise are likely to be larger than in the case of coarse crushing. In the arrangement pattern D, it is possible to improve the convenience of the office user while avoiding the influence of vibration and noise at the time of defibration on the office.

Further, the crushed product obtained by the third device 110C is carried to the backyard by a user or the like.

The user can procure the coarsely crushed material in the backyard and obtain the defibrated fiber which is the raw material of the sheet S by the second device 110B arranged in the backyard. Since the second device 100B, which is a sheet manufacturing device, is also arranged in the backyard, the defibrated fiber can be easily set in the second device 100B to manufacture the sheet S. Therefore, the user can easily procure the seat S in the backyard.

The arrangement pattern E is advantageous for preventing leakage of confidential materials, and since the defibration and sheet production are performed in the backyard, vibration and noise associated with the defibration can be prevented from being generated in the office.

Further, the arrangement pattern C'shown in FIG. 5 is similar to the arrangement pattern C when the sheet manufacturing system 1 is composed of two devices 100A and 100B. That is, the third device 110C and the first device 110A, which are coarse crushing devices, are arranged in the office, and the second device 100B, which is a sheet manufacturing device, is arranged in the backyard.

That is, the third device 110C can be placed in a place where used paper is generated in the office, and the first device 110A can be placed in a place in the office where the influence of vibration and noise is small.

(Third Embodiment)
FIG. 6 is a block diagram showing a configuration including a control system of the seat manufacturing system 1 according to the third embodiment.
The third embodiment is different from the second embodiment in that the first device 110A and the second device 100B of the second embodiment are composed of one device (hereinafter, the fourth device) 120A. .. The same parts as those in the above embodiments are designated by the same reference numerals, the description thereof will be omitted, and the different parts will be described in detail.
The fourth device 120A includes a coarsely crushed material supply unit 45A, a defibration unit 20, a sorting unit 30, an additive mixing unit 50, a depositing unit 60, a sheet forming unit 70, and a cutting unit 90. That is, the fourth device 120A functions as a device for performing defibration and sheet production. Hereinafter, for convenience of explanation, when the fourth device 120A is functionally described, it is appropriately described as "defibration / sheet manufacturing device".

Further, the fourth device 120A has a control device 121A, an operation unit 122A, a display unit 123A, and a remaining amount sensor 124A, and can operate independently under the control of the control device 121A. The control device 121A is a computer system composed of a main processor, a ROM, a RAM, and the like. The control device 121A executes each part (crude material supply part 45A, defibration part 20, sorting part 30, additive mixing part 50) of the fourth device 120A by executing the basic control program stored in the ROM by the main processor. , The depositing portion 60, the sheet forming portion 70, and the cutting portion 90) are controlled. The operation unit 122A inputs various instructions to the fourth device 120A.

The control device 121A can control each part of the fourth device 120A after the power of the fourth device 120A is turned on and the activation sequence is executed. In this case, the control device 121A via the operation unit 122A gives an instruction to start manufacturing the sheet S, manufacturing conditions (density (basis weight) of the sheet S, shape (size, thickness), color, manufacturing quantity (number of manufactured sheets)). Etc.), production start date and time (schedule), etc. can be accepted. Then, when the manufacturing instruction is input or the manufacturing start date and time reached the preset manufacturing start date and time, the control device 121A solves the coarse crushed material in the cartridge 210 by operating each part of the fourth device 120A. Sheet S is produced from defibrated fibers according to the production conditions.

The display unit 123A displays various information related to the fourth device 120A under the control of the control device 121A. The remaining amount sensor 124A detects the remaining amount of the raw material and / or the manufactured sheet S in the fourth device 120A, and outputs the detection result to the control device 121A. The remaining amount sensor 124A of this configuration detects, for example, the remaining amount of the crushed material in the cartridge 210 mounted on the crushed material supply unit 45A.

When the control device 121A detects that the remaining amount of the coarse crushed material in the fourth device 120A is less than the set value, the control device 121A performs a notification process for notifying the shortage of the crushed material (for example, replacement of the cartridge 210). The notification process includes display on the display unit 123A, audio output by an audio output unit (not shown), and the like. When the fourth device 120A is connected to another device (for example, a PC operated by a user) via a communication network, the other device may be notified of the shortage of coarse crushed material.

Further, the control device 121A records the operation history of the fourth device 120A in a memory (not shown), and performs a measurement process for measuring the sheet production amount indicating the fiber processing amount based on the operation history. The operation history is, for example, information in which the number of sheets S manufactured and the date and time of manufacture are associated with each other. Further, in this configuration, the control device 121A counts the manufactured amount (manufactured number of sheets) of the sheet S based on the operation history, and records this counted value as the sheet manufactured amount in a memory (not shown). The control device 121A can notify the user and the like of the sheet production amount by displaying the sheet production amount on the display unit 123A. Instead of the method of measuring the number of sheets to be manufactured, the amount of coarsely crushed material taken out from the cartridge 210 or the amount of second web W2 manufactured may be measured.

For example, the third apparatus 110C, which is a coarse crushing apparatus, is arranged in the office, and the fourth apparatus 120A, which is a defibration / sheet manufacturing apparatus, is arranged in the backyard (see FIG. 6). This arrangement is referred to as an arrangement pattern E'.
The arrangement pattern E'is similar to the arrangement pattern E when the sheet manufacturing system 1 is composed of three devices 110C, 110A, and 100B.
In the case of the arrangement pattern E', the user can coarsely crush the used paper such as the confidential paper by the third device 110C arranged in the office, which is advantageous in preventing the leakage of the confidential paper. Further, the crushed product produced by the third device 110C is carried to the backyard by a user or the like.

The user can procure the coarsely crushed material in the backyard and have the sheet S manufactured by the fourth device 120A arranged in the backyard. This has the same effect as the arrangement pattern E, that is, it is advantageous in preventing the leakage of confidential information, and since the defibration and sheet manufacturing are performed in the backyard, vibration and noise associated with the defibration are not generated in the office. You can get the effect of being able to do it.

For example, in an office where the amount of seats produced is small, it becomes easy to take measures such as stopping the arrangement of the second device 100B or moving the second device 100B to another office. In addition, it becomes easy to take measures such as moving the first device 100A to a position close to the office where the amount of sheets manufactured is large. Further, when a printing device is arranged in each office, even if the printing amount in each office is grasped and the first device 100A is moved to a position close to the office where the printing amount is large, the first device 100A may be moved. good.

(Fifth Embodiment)
FIG. 8 is a diagram showing an outline configuration of the sheet manufacturing system 1 according to the fifth embodiment.
A fifth embodiment allows the sheet S to be coarsely crushed and defibrated in a plurality of offices X1, X2, X3. Hereinafter, the points different from the first embodiment will be described.
The first device 100A, which is a crushing / defibrating device, is arranged in each of the offices X1, X2, and X3. Further, the second device 100B, which is a sheet manufacturing device, is arranged in the backyard. That is, the fifth embodiment is an arrangement corresponding to the above-mentioned arrangement pattern C.

In each of the offices X1, X2, and X3, a collection box 11 for collecting used paper is arranged in each office. Further, FIG. 8 shows a PC used by the user of each office X1 to X3 (indicated by reference numerals 1X, 2X and 3X in FIG. 8) and a user for printing in each office X1 to X3. A printing device (indicated by reference numerals 1Y, 2Y, and 3Y in FIG. 8) is shown. The PCs 1X, 2X, 3X and the printing devices 1Y, 2Y, and 3Y are communicably connected via the communication network NW. The communication network NW is a wired or wireless communication network, and a known communication network can be widely applied.

As shown in FIG. 8, since the first device 100A, which is a coarse crushing / defibrating device, is arranged in each of the offices X1, X2, and X3, the user can coarsely crush used paper such as confidential paper in the office. And can be defibrated, which is advantageous in preventing the leakage of confidential information. Further, since the collection box 11 is arranged in each of the offices X1, X2, and X3, the used paper collected in the collection box 11 can be roughly crushed and defibrated in the office by the first device 100A. ..

Further, as shown by an arrow in FIG. 8, the cartridge 200 discharged from the first device 100A is carried to the backyard and set in the second device 100B arranged in the backyard to manufacture the sheet S. Used for. Then, the manufactured sheet S is carried from the backyard to the offices X1, X2, and X3, and is set in the printing devices 1Y, 2Y, and 3Y of the offices X1, X2, and X3. As a result, the print data from the PCs 1X, 2X, and 3X of the offices X1 to X3 can be printed on the sheet S.

In this way, while the used paper can be coarsely crushed and defibrated in each office X1, X2, X3, the second device 100B, which is a sheet manufacturing apparatus, can be shared by the users of each office X1, X2, X3. .. Therefore, the number of the second devices 100B can be reduced while obtaining the effect of the arrangement pattern C.

As described above, in the first device 100A arranged in each office X1, X2, X3, the control device 101A measures the amount of recycled paper processed indicating the amount of coarse crushing and defibration. By confirming the amount of these sheets produced by the user or the like, the amount of used paper processed in each office X1, X2, X3 can be compared. This comparison result provides useful information for improving the arrangement of the first device 100A. For example, in an office where the amount of used paper processed is small, it becomes easy to take measures such as stopping the arrangement of the first device 100A or moving the first device 100A to another office. Further, it is possible to move the second device 100B to a position close to the office where the amount of used paper processed is large.

(Sixth Embodiment)
The sixth embodiment is different from the first embodiment in that the second apparatus 100B, which is a sheet manufacturing apparatus, has a printing unit 1Z for printing on the sheet S.
FIG. 9 is a block diagram showing a configuration including a control system of the second device 100B of the sixth embodiment. The second device 100B is provided with a sheet supply mechanism (not shown) that supplies the sheet S discharged to the discharge unit 96 to the printing unit 1Z, and the printing unit 1Z can print on the manufactured sheet S.

Further, the second device 100B is provided with a communication unit 105B for communicating with an external device (PC1X, 2X, 3X, etc. in the example of FIG. 9) via the communication network NW. The control device 101B of the second device 100B receives print data from external devices such as PC1X, 2X, 3X, etc. by the communication unit 105B. Then, when the print data is received, the control device 101B performs print control for printing the print image corresponding to the print data on the sheet S by the print unit 1Z. According to this configuration, the installation efficiency of the equipment is improved as compared with the case where a separate printing device is arranged.

Here, when the control device 101B receives the print data as the print start instruction, the control device 101B may manufacture the sheet S by using the print start instruction as a trigger.
FIG. 10 is a flowchart showing an operation example when the sheet S is manufactured by using the print start instruction as a trigger.
When the control device 101B receives the print data (corresponding to the print start instruction) (step S1D; YES), the control device 101B determines whether or not the sheet S needs to be manufactured based on the print amount specified by the print data (step S2D). ).

Whether or not the sheet S needs to be manufactured is determined based on the remaining amount of the sheet S remaining in the discharge unit 96. For example, the control device 101B is configured to be able to detect the remaining amount of the sheet S remaining in the discharging unit 96 by the remaining amount sensor 104B, and when the remaining amount of the sheet S is equal to or more than the printing amount, the production of the sheet S is unnecessary. (Step S2D; NO). In this case, the control device 101B starts the control of feeding the sheet S remaining in the discharge unit 96 to the printing unit 1Z (step S3D). Next, the control device 101B determines whether or not to end the paper feeding (step S4D). When the control device 101B supplies the sheet S to be printed to the printing unit 1Z by the amount to be printed, the control device 101B determines that the paper feeding is finished (step S4D; YES), and stops the paper feeding (step S5D).

In step S2D, when the sheet S remaining in the ejection unit 96 is less than the print amount (when the print amount is not satisfied), the control device 101B determines that the sheet S needs to be manufactured (step S2D; YES). Even if the remaining amount of the sheet S is equal to or more than the printing amount, if it is less than the preset remaining amount, it may be determined that the sheet S needs to be manufactured. When it is determined that the production of the sheet S is necessary (step S2D; YES), the control device 101B shifts to the process of step S6D, sets the insufficient sheet S as the sheet to be manufactured, and secures the shortage number of sheets. To identify. The target production amount may be the same as the insufficient number of sheets, or may be set to a larger number than the insufficient number of sheets. Next, the control device 101B starts manufacturing the sheet S to be manufactured (step S7D).

The control device 101B determines whether or not to end the production of the sheet S (step S8D), and when the production is finished, stops the operation of each part of the second device 100B (step S9D). The case where the production is terminated is a case where the production amount of the sheet S reaches the target production amount and the like.
Subsequently, the control device 101B starts the control of feeding the manufactured sheet S to the printing unit 1Z via the discharging unit 96 (step S10D). Further, the control device 101B determines whether or not to end the paper feeding of the sheet S (step S11D), and when the paper feeding is finished, stops the paper feeding control (step S12D). The case of ending the paper feeding is a case where the number of sheets S corresponding to the printing amount is supplied to the printing unit 1Z. As described above, when the sheet S to be printed is insufficient, the insufficient sheet S can be manufactured and fed to the printing unit 1Z.

In this way, since the sheet S is manufactured by using the print start instruction as a trigger, the sheet S can be manufactured on demand in response to the print start instruction. Moreover, since it is determined whether or not to manufacture the sheet S based on the remaining amount of the sheet S, the sheet S can be appropriately and automatically replenished according to the remaining amount of the sheet S. Further, since the second device 100B, which is a sheet manufacturing device, and the printing unit 1Z are integrated, the sheet S can be manufactured and the printed sheet S can be smoothly printed. It should be noted that printing on the sheet S may be performed in parallel while manufacturing the sheet S.

In the sixth embodiment, the second device 100B may be configured to electrostatically manufacture the sheet S.
FIG. 11 is a schematic view showing a main part (hereinafter, referred to as a sheet manufacturing part 75) when the sheet S is manufactured by the electrostatic type.
The sheet manufacturing unit 75 manufactures the sheet S by electrostatically transferring the fiber-containing material that is the raw material of the sheet S to the transport belt 401 (transferred body) and performing a post-treatment for adjusting the surface texture.
The sheet manufacturing unit 75 includes a supply unit 410 for supplying the fiber-containing material, a carrier 420 (second carrier) for supporting the supplied fiber-containing material, and a transport belt on which the supported fiber-containing material is electrostatically transferred. It has 401 and a post-processing unit 430 that performs post-processing.

In the sheet manufacturing unit 75, the fiber-containing material is electrostatically transferred from the carrier 420 to the transferee (conveyor belt 401). As a result, it is possible to prevent the amount of the fiber-containing material adhering to the transferred body (conveying belt 401) from varying, that is, the fiber-containing material adheres to the transferred body (conveying belt 401) in just proportion. As a result, the sheet S obtained from the fiber-containing material can be stably produced with a uniform thickness.

The fiber-containing material as a raw material is composed of a composite containing cellulose fibers and a hydrophobic material covering at least a part of the cellulose fibers, and is pressurized and heated by the post-treatment unit 430 to obtain the sheet S. Is formed.
The cellulose fiber may be derived from a cellulose product such as used paper or virgin pulp, and fibers containing cellulose can be widely applied. For example, cellulose fibers obtained by defibrating used paper can be used.

The hydrophobic material forms the sheet S by binding the cellulose fibers to each other. In addition, the hydrophobic material coats the cellulose fibers and stabilizes the charging properties of the complex. Thereby, the sheet S can be suitably formed by electrostatic coating. As the hydrophobic material, for example, a thermoplastic resin, a curable resin, or the like can be used.
Further, the hydrophobic material may contain a charge control agent (charge control agent) for obtaining desired charge characteristics, or a colorant for adjusting the color of the sheet S.

As shown in FIG. 11, the supply unit 410 houses the storage unit 412, the stirrer 413 (agitator), the roller 414, the first carrier 415, and the blade 416 in the housing unit 411.
The storage unit 412 stores a fiber-containing material containing a cellulose fiber and a thermoplastic resin. The stirrer 413 stirs the fiber-containing material in the storage unit 412, and charges the fiber-containing material by friction during stirring. This fiber-containing material is supplied to the first carrier 415 by rotation of the roller 414. The first carrier 415 has a potential difference with the roller 414, and the fiber-containing material is electrostatically adhered to the first carrier 415. The blade 416 adjusts the thickness (adhesion amount) of the fiber-containing material attached to the first carrier 415 to form a sheet having a predetermined thickness (thinning), and charges the fiber-containing material by friction.

The carrier 420 has a potential difference with the first carrier 415, and the fiber-containing material is electrostatically attached. The carrier 420 is a rotating roller member, and the fiber-containing material supported on the carrier 420 is transferred to the transport belt 401.
Around the carrier 420, a charging portion 422 that charges the outer peripheral surface 421 of the carrier 420 and an exposed portion 423 that adjusts the potential of the outer peripheral surface 421 are provided. Further, around the carrier 420, a transfer unit 424 for transferring the fiber-containing material to the transport belt 401 by the electrostatic force generated by the potential difference between the carrier 420 and the carrier 420 is provided.

Further, the transfer unit 424 pressurizes the fiber-containing material transferred to the transport belt 401 with the carrier 420 to adjust the thickness of the fiber-containing material to a uniform thickness. The transport belt 401 is composed of an endless belt and is conveyed by a plurality of rollers 402. The transport belt 401 is preferably made of a resin having a medium / high resistance (volume resistivity 107 to 1011 Ω · cm) on the surface on which the fiber-containing material is transferred. Such a constituent material is not particularly limited, and for example, a material obtained by kneading carbon black with a fluororesin can be used. As a result, the powder of the fiber-containing material is transferred to the transport belt 401 by a potential difference, and it becomes easier to electrostatically hold the powder on the transport belt 401.

The post-treatment section 430 includes a leveling treatment section 431 that smoothes the surface of the fiber-containing material transferred to the transport belt 401, a pressure treatment section 432 that pressurizes the fiber-containing material, and a semi-solidification section that semi-solidifies the surface of the fiber-containing material. It includes a solidification processing unit 433 and a solidification unit 434 that solidifies the layered fiber-containing material.
