The fourth accommodating portion 104 is an option that is appropriately added and can be omitted.

FIG. 2 is a schematic diagram showing the configuration of the sheet manufacturing unit 101.
The sheet manufacturing unit 101 includes a supply unit 10, a crushing unit 12, a defibrating unit 20, a sorting unit 40, a first web forming unit 45, a rotating body 49, a mixing unit 50, a depositing unit 60, a second web forming unit 70, The transport unit 79, the sheet forming unit 80, the cutting unit 90, and the sorting unit 95 are provided.

Further, the sheet manufacturing apparatus 100 includes humidifying units 202, 204, 206, 208, 210 and 212 for the purpose of humidifying the raw material and/or humidifying the space where the raw material moves. Specific configurations of the humidifying units 202, 204, 206, 208, 210, 212 are arbitrary, and examples thereof include a steam type, a vaporizing type, a warm air vaporizing type, and an ultrasonic type.

In the present embodiment, the humidifiers 202, 204, 206, 208 are constituted by vaporizers or warm air vaporizers. That is, each of the humidifying units 202, 204, 206, and 208 has a filter (not shown) that partially moistens water, and supplies humidified air with increased humidity by passing air through the filter. Further, the humidifying units 202, 204, 206, 208 may include a heater (not shown) that effectively increases the humidity of the humidified air.

In addition, in the present embodiment, the humidifying section 210 and the humidifying section 212 are configured by an ultrasonic humidifier. That is, the humidifying sections 210 and 212 have a vibrating section (not shown) that atomizes water, and supplies mist generated by the vibrating section.

The supply unit 10 supplies the raw material to the crushing unit 12. The raw material from which the sheet manufacturing apparatus 100 manufactures a sheet may be any as long as it contains fibers, and examples thereof include paper, pulp, a pulp sheet, cloth including non-woven fabric, and woven fabric. This embodiment exemplifies a configuration in which the sheet manufacturing apparatus 100 uses waste paper as a raw material.

The crushing unit 12 crushes the raw material supplied by the supplying unit 10 with a crushing blade 14 to form a crushed piece (a crushed material). The coarse crushing blade 14 is a blade for roughly crushing the raw material in the air (in the air) or the like. The coarse crushing unit 12 includes a pair of coarse crushing blades 14 for performing coarse crushing with the raw material sandwiched between them, and a drive unit for rotating the coarse 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 process in the defibration unit 20. For example, the crushing unit 12 crushes the raw material into pieces of paper having a size of 1 to several cm square or smaller.

The coarse crushing section 12 has a chute (also referred to as a hopper) 9 that receives coarse crushed pieces that are roughly crushed by the coarse crushing blade 14 and fall. The chute 9 has, for example, a taper shape in which the width gradually narrows in the direction in which the coarsely crushed pieces flow (the direction in which the coarsely crushed pieces move), and functions as a guide unit that receives and collects the coarsely crushed pieces that diffuse below the coarse crushing blade 14. .. The chute 9 is connected to a pipe 2 communicating with the defibrating unit 20, and the pipe 2 forms a conveying path for conveying the raw material (coarse fragments) crushed by the crushing blade 14 to the defibrating unit 20. To do. The coarsely crushed pieces are collected by the chute 9 and transferred (conveyed) to the defibrating unit 20 through the tube 2. As a result, the pipe 2 functions as a discharge unit for discharging the coarsely crushed pieces collected by the chute 9.

Humidified air is supplied by the humidifying unit 202 to the chute 9 of the crushing unit 12 or the vicinity of the chute 9. As a result, it is possible to suppress the phenomenon that the roughly crushed material roughly crushed by the crushing blade 14 is adsorbed to the chute 9 or the inner surface of the tube 2 due to static electricity. Further, since the coarsely crushed material coarsely crushed by the coarsely crushing blade 14 is transferred to the defibrating unit 20 together with humidified (high humidity) air, an effect of suppressing adhesion of defibrated substances inside the defibrating unit 20. Can be expected. Further, the humidifying unit 202 may be configured to supply humidified air to the coarsely crushing blade 14 to remove the charge of the raw material supplied by the supply unit 10.

The defibrating unit 20 defibrates the coarsely crushed material crushed by the crushing unit 12. More specifically, the defibrating unit 20 defibrates the coarsely crushed pieces crushed by the crushing unit 12 as a raw material to generate a defibrated material. Here, "to disintegrate" means to disintegrate the raw material (the material to be disintegrated) formed by binding a plurality of fibers into individual fibers. The defibrating unit 20 also has a function of separating substances such as resin particles, ink, toner, and anti-bleeding agent attached to the raw material from the fibers.

What has passed through the defibrating unit 20 is referred to as a “defibrated material”. "Disentangled material" includes, in addition to disentangled disentangled fibers, resin particles (resin for binding a plurality of fibers) separated from the fibers when disentangled, ink, toner, etc. In some cases, additives such as the colorant, anti-bleeding agent, and paper strengthening agent are included. The shape of the disentangled defibrated material is a string shape or a ribbon shape. The disentangled defibrated material may exist in a state not entangled with other defibrated defibrated material (independent state), or entangled with other defibrated defibrated material to form a lump. It may exist in the state of becoming (a state of forming a so-called “damage”).

The defibrating unit 20 performs defibration by a dry method. Here, performing the treatment such as defibration in air (in air) or the like, not in liquid, is referred to as a dry method. In this embodiment, the defibrating unit 20 uses an impeller mill. Specifically, the defibrating unit 20 includes a toler (not shown) that rotates at a high speed, and a liner (not shown) located on the outer circumference of the roller. The coarsely crushed pieces coarsely crushed by the coarse crushing unit 12 are sandwiched between the rotor and the liner of the defibrating unit 20 to be defibrated. The defibrating unit 20 generates an airflow by the rotation of the rotor. By this air flow, the defibrating unit 20 can suck the coarsely crushed material, which is a raw material, from the tube 2 and convey the defibrated material to the discharge port 24. The defibrated material is sent out from the outlet 24 to the pipe 3, and transferred to the sorting unit 40 via the pipe 3.

In this way, the defibrated material generated in the defibration unit 20 is conveyed from the defibration unit 20 to the sorting unit 40 by the airflow generated by the defibration unit 20. Further, in the present embodiment, the sheet manufacturing apparatus 100 includes the defibrating unit blower 26 that is an airflow generating device, and the defibrated material is conveyed to the sorting unit 40 by the airflow generated by the defibrating unit blower 26. The defibrating unit blower 26 is attached to the tube 3, sucks air together with the defibrated material from the defibrating unit 20, and blows the air to the sorting unit 40.

The sorting unit 40 has an inlet 42 through which the defibrated material defibrated by the defibrating unit 20 from the tube 3 flows in together with the airflow. The sorting unit 40 sorts the defibrated material introduced into the introduction port 42 according to the length of the fiber. Specifically, the sorting unit 40 sets a defibrated product having a predetermined size or less among the defibrated products defibrated by the defibrating unit 20 as a first selected product, and a defibrated product larger than the first selected product. Is selected as the second selected product. The first sorted material includes fibers, particles, and the like, and the second sorted material is, for example, large fibers, unfibrillated pieces (coarse pieces that have not been sufficiently defibrated), and defibrated fibers aggregate, or Including entangled balls.

In the present embodiment, the selection unit 40 has a drum unit 41 (sieve unit) and a housing unit 43 (cover unit) that accommodates the drum unit 41.
The drum portion 41 is a cylindrical sieve that is rotationally driven by a motor. The drum portion 41 has a net (filter, screen) and functions as a sieve. With this mesh, the drum portion 41 sorts a first sorted product having a smaller mesh opening (opening) and a second sorted product having a larger mesh opening. As the net of the drum portion 41, for example, a wire net, an expanded metal obtained by extending a notched metal plate, or a punching metal having holes formed in the metal plate by a press machine or the like can be used.

The defibrated material introduced into the introduction port 42 is sent into the inside of the drum portion 41 together with the airflow, and the rotation of the drum portion 41 causes the first sorted material to drop downward from the mesh of the drum portion 41. The second sorted matter that cannot pass through the mesh of the drum portion 41 is flowed by the airflow flowing into the drum portion 41 from the introduction port 42, guided to the discharge port 44, and sent out to the pipe 8.
The pipe 8 connects the inside of the drum portion 41 and the pipe 2. The second sorted material flowing through the pipe 8 flows through the pipe 2 together with the coarsely crushed pieces crushed by the crushing unit 12, and is guided to the inlet 22 of the defibrating unit 20. As a result, the second sorted material is returned to the defibrating unit 20 and defibrated.

Further, the first sorted matter sorted by the drum portion 41 passes through the mesh of the drum portion 41 and is dispersed in the air, and is distributed to the mesh belt 46 of the first web forming portion 45 located below the drum portion 41. Descend towards.

The first web forming unit 45 (separation unit) includes a mesh belt 46 (separation belt), a roller 47, and a suction unit 48 (suction mechanism). The mesh belt 46 is an endless belt, is suspended by three rollers 47, and is conveyed in the direction indicated by the arrow in the figure by the movement of the rollers 47. The surface of the mesh belt 46 is formed of a net having openings of a predetermined size. Of the first sorted matter descending from the sorting section 40, fine particles having a size that can pass through the mesh are dropped below the mesh belt 46, and fibers having a size that cannot pass through the mesh are deposited on the mesh belt 46 to form a mesh. The belt 46 is conveyed in the direction of the arrow. The fine particles that fall from the mesh belt 46 include those that are relatively small or have a low density (resin particles, coloring agents, additives, etc.) among the defibrated materials, and are not used by the sheet manufacturing apparatus 100 for manufacturing the sheet. It is a thing.

The mesh belt 46 moves at a constant speed V1 during the normal operation of manufacturing a sheet. Here, “during normal operation” refers to an operation other than during execution of start control and stop control of the sheet manufacturing apparatus 100, which will be described later, and more specifically, the sheet manufacturing apparatus 100 manufactures sheets of desired quality. It refers to while
Therefore, the defibrated material that has been defibrated by the defibrating unit 20 is sorted by the sorting unit 40 into the first sorted material and the second sorted material, and the second sorted material is returned to the defibrated portion 20. Further, the removed material is removed from the first sorted material by the first web forming unit 45. The remainder of the first sorted material after removing the removed material is a material suitable for manufacturing a sheet, and this material is deposited on the mesh belt 46 to form the first web W1.

The suction unit 48 sucks air from below the mesh belt 46. The suction unit 48 is connected to the dust collecting unit 27 via the pipe 23. The dust collector 27 is a filter-type or cyclone-type dust collector, and separates fine particles from the air stream. A collection blower 28 (separation suction unit) is installed downstream of the dust collection unit 27, and the collection blower 28 functions as a dust collection suction unit that sucks air from the dust collection unit 27. Further, it is discharged to the outside of the sheet manufacturing apparatus 100 via a pipe 29 discharged from the collection blower 28.

In this configuration, the collection blower 28 sucks air from the suction portion 48 through the dust collecting portion 27. In the suction section 48, the fine particles passing through the mesh of the mesh belt 46 are sucked together with the air and sent to the dust collecting section 27 through the tube 23. The dust collecting unit 27 separates and accumulates the fine particles that have passed through the mesh belt 46 from the air flow.

Therefore, the fibers obtained by removing the removed material from the first sorted material are accumulated on the mesh belt 46 to form the first web W1. The collection blower 28 sucks, whereby the formation of the first web W1 on the mesh belt 46 is promoted, and the removed matter is promptly removed.

Humidified air is supplied to the space including the drum portion 41 by the humidifying portion 204. The humidified air humidifies the first sorted material inside the sorting unit 40. This weakens the adhesion of the first sorted matter to the mesh belt 46 due to the electrostatic force and facilitates the peeling of the first sorted matter from the mesh belt 46. Further, it is possible to prevent the first sorted matter from adhering to the rotating body 49 and the inner wall of the housing portion 43 by the electrostatic force. Further, the suction unit 48 can efficiently suck the removed substance.

In the sheet manufacturing apparatus 100, the configuration for selecting and separating the first defibrated material and the second defibrated material is not limited to the selection unit 40 including the drum unit 41. For example, the defibrated material that has been defibrated by the defibrating unit 20 may be classified by a classifier. As the classifier, for example, a cyclone classifier, an elbow jet classifier, or an eddy classifier can be used. By using these classifiers, it is possible to sort and separate the first sorted product and the second sorted product. Further, by the above classifier, it is possible to realize a configuration in which the removed substances including relatively small defibrated substances and low defibrated substances (resin particles, coloring agents, additives, etc.) are separated and removed. For example, the fine particles contained in the first sorted material may be removed from the first sorted material by a classifier. In this case, the second sorted matter may be returned to, for example, the defibrating unit 20, the removed matter may be collected by the dust collecting section 27, and the first sorted matter excluding the removed matter may be sent to the pipe 54. ..

Air containing mist is supplied to the downstream side of the sorting unit 40 in the transport path of the mesh belt 46 by the humidifying unit 210. The mist, which is fine particles of water generated by the humidifying section 210, descends toward the first web W1 and supplies moisture to the first web W1. As a result, the amount of water contained in the first web W1 is adjusted, and the adsorption of fibers to the mesh belt 46 due to static electricity can be suppressed.

The sheet manufacturing apparatus 100 includes a rotating body 49 that divides the first web W1 accumulated on the mesh belt 46. The first web W<b>1 is separated from the mesh belt 46 at the position where the mesh belt 46 is folded back by the roller 47 and is divided by the rotating body 49.

The first web W1 is a soft material in which fibers are deposited to form a web shape, and the rotating body 49 unravels the fibers of the first web W1 and processes the resin into a state where it is easy to mix the resin in the mixing unit 50 described later. ..

The configuration of the rotating body 49 is arbitrary, but in the present embodiment, the rotating body 49 can have a rotating blade shape having plate-shaped blades and rotating. The rotating body 49 is arranged at a position where the first web W<b>1 separated from the mesh belt 46 and the blade come into contact with each other. Due to the rotation of the rotating body 49 (for example, rotation in the direction indicated by the arrow R in the drawing), the blades collide with the first web W1 separated from the mesh belt 46 and conveyed to be divided, and the subdivided body P is generated.
The rotating body 49 is preferably installed at a position where the blades of the rotating body 49 do not collide with the mesh belt 46. For example, the distance between the tips of the blades of the rotating body 49 and the mesh belt 46 can be set to 0.05 mm or more and 0.5 mm or less. In this case, the rotating body 49 prevents the mesh belt 46 from being damaged without damaging the mesh belt 46. The 1 web W1 can be efficiently divided.

The subdivided body P divided by the rotating body 49 descends inside the tube 7 and is transferred (conveyed) to the mixing section 50 by the airflow flowing inside the tube 7.
Humidifying air is supplied to the space including the rotating body 49 by the humidifying unit 206. As a result, it is possible to suppress the phenomenon that the fibers are adsorbed to the inside of the tube 7 and the blades of the rotating body 49 due to static electricity. Further, since air with high humidity is supplied to the mixing section 50 through the pipe 7, the influence of static electricity can be suppressed also in the mixing section 50.

The mixing unit 50 includes an additive supply unit 52 that supplies an additive containing a resin, a pipe 54 that communicates with the pipe 7, and through which an air flow containing the subdivided body P flows, and a mixing blower 56.
The subdivided body P is a fiber obtained by removing the removed material from the first sorted material that has passed through the sorting unit 40 as described above. The mixing unit 50 mixes the fiber forming the subdivided body P with an additive containing a resin.

In the mixing section 50, an air flow is generated by the mixing blower 56, and the subdivided body P and the additive are conveyed while being mixed in the pipe 54. Further, the subdivided body P is loosened in the process of flowing inside the pipe 7 and the pipe 54, and becomes finer fibrous.

The additive supply unit 52 (resin accommodating unit) is connected to an additive cartridge (not shown) that accumulates the additive, and supplies the additive inside the additive cartridge to the pipe 54. The additive cartridge may be detachable 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 temporarily stores the additive made of fine powder or fine particles inside the additive cartridge. The additive supply unit 52 has a discharge unit 52a (resin supply unit) that sends the once-stored additive to the pipe 54.

The discharge unit 52a includes a feeder (not shown) that sends the additive stored in the additive supply unit 52 to the pipe 54, and a shutter (not shown) that opens and closes the pipe line that connects the feeder and the pipe 54. .. When this shutter is closed, the pipe line or the opening connecting the discharge part 52a and the pipe 54 is closed, and the supply of the additive from the additive supply part 52 to the pipe 54 is cut off.

While the feeder of the discharge part 52a is not operating, the additive is not supplied from the discharge part 52a to the pipe 54, but when a negative pressure is generated in the pipe 54, the feeder of the discharge part 52a is stopped. However, the additive may flow to the pipe 54. By closing the discharge part 52a, the flow of such an additive can be reliably interrupted.

The additive supplied by the additive supply unit 52 contains a resin for binding a plurality of fibers. The resin contained in the additive is a thermoplastic resin or a thermosetting resin, and examples thereof include AS resin, ABS resin, polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylic resin, polyester resin, polyethylene terephthalate, polyphenylene ether, and polyphenylene ether. Butylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like. These resins may be used alone or in an appropriate mixture. That is, the additive may include a single substance, may be a mixture, and may include 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 fiber or powder.
The resin contained in the additive is melted by heating to bind the plurality of fibers to each other. Therefore, the fibers are not bound to each other in a state where the resin is mixed with the fibers and is not heated to a temperature at which the resin melts.

In addition to the resin that binds the fibers, the additive supplied by the additive supply unit 52 may be a colorant for coloring the fibers, agglomeration of the fibers or a resin depending on the type of the sheet S to be manufactured. It contains a coagulation inhibitor for suppressing coagulation and a flame retardant for making fibers and the like difficult to burn. Further, the additive containing no colorant may be colorless, or may be a light color that can be regarded as colorless, or may be white.

Due to the air flow generated by the mixing blower 56, the subdivided body P that descends in the pipe 7 and the additive supplied by the additive supply unit 52 are sucked into the pipe 54 and pass through the inside of the mixing blower 56. By the action of the air flow generated by the mixing blower 56 and/or the action of the rotating part such as a blade of the mixing blower 56, the fibers constituting the subdivided body P and the additive are mixed, and the mixture (the first selected product and the additive) is mixed. Mixture) is transferred to the deposition section 60 through the pipe 54.

The mechanism for mixing the first selection product and the additive is not particularly limited, and may be a stirring device using a blade that rotates at high speed, or a device that uses the rotation of a container such as a V-type mixer. There may be, and these features may be installed before or after the mixing blower 56.

The deposition unit 60 deposits the defibrated material defibrated by the defibration unit 20. More specifically, the deposition unit 60 introduces the mixture that has passed through the mixing unit 50 from the introduction port 62, loosens the entangled defibrated material (fibers), and disperses the defibrated material (fibers) in the air. Furthermore, when the additive resin supplied from the additive supply unit 52 is fibrous, the deposition unit 60 loosens the entangled resin. Thereby, the deposition unit 60 can deposit the mixture on the second web forming unit 70 with good uniformity.

The deposition unit 60 includes a drum unit 61 (drum) and a housing unit 63 (covering unit) that houses the drum unit 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. Due to this mesh, the drum portion 61 allows fibers and particles having a smaller mesh opening (opening) to pass through and lowers from the drum portion 61. The configuration of the drum portion 61 is the same as the configuration of the drum portion 41, for example.

The “sieve” of the drum unit 61 does not have to have a function of selecting a specific object. That is, the “sieve” used as the drum portion 61 means that it has a net, and the drum portion 61 may drop all the mixture introduced into the drum portion 61.

The second web forming unit 70 is arranged below the drum unit 61. The second web forming unit 70 deposits the passing material that has passed through the depositing unit 60 to form a second web W2 (a deposit). The second web forming unit 70 includes, for example, a mesh belt 72 (belt), a roller 74, and a suction mechanism 76.

The mesh belt 72 is an endless belt, is suspended by a plurality of rollers 74, and is conveyed in the direction indicated by the arrow in the figure by the movement of the rollers 74. The mesh belt 72 is made of, for example, metal, resin, cloth, or non-woven fabric. The surface of the mesh belt 72 is composed of a net having openings of a predetermined size. Among the fibers and particles falling from the drum portion 61, the fine particles having a size that can pass through the mesh are dropped below the mesh belt 72, and the fibers having a size that cannot pass through the mesh are accumulated on the mesh belt 72. It is conveyed together with 72 in the arrow direction. The mesh belt 72 moves at a constant speed V2 during the operation of manufacturing the sheet S.

The mesh of the mesh belt 72 is fine, and the mesh belt 72 may have a size that does not allow most of the fibers and particles falling from the drum portion 61 to pass through.
The suction mechanism 76 is provided below the mesh belt 72 (on the side opposite to the deposition unit 60 side). The suction mechanism 76 includes a suction blower 77, and the suction force of the suction blower 77 can generate a downward airflow (an airflow toward the mesh belt 72 from the deposition unit 60) in the suction mechanism 76.

The suction mechanism 76 sucks the mixture dispersed in the air by the deposition unit 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 discharging speed from the deposition unit 60 can be increased. Further, the suction mechanism 76 can form a downflow in the dropping path of the mixture, and can prevent the defibrated material and the additives from being entangled with each other during the fall.
The suction blower 77 (deposition suction unit) may discharge the air sucked from the suction mechanism 76 to the outside of the sheet manufacturing apparatus 100 through a collection filter (not shown). Alternatively, the air sucked by the suction blower 77 may be sent to the dust collecting unit 27, and the removed substances contained in the air sucked by the suction mechanism 76 may be collected.

Humidified air is supplied to the space including the drum portion 61 by the humidifying portion 208. This humidified air can humidify the inside of the deposition unit 60, suppress the adhesion of fibers and particles to the housing unit 63 due to electrostatic force, and quickly drop the fibers and particles onto the mesh belt 72. Two webs W2 can be formed.

As described above, the second web W2 that contains a large amount of air and is soft and inflated is formed through the deposition section 60 and the second web forming section 70 (web forming step). The second web W2 deposited on the mesh belt 72 is conveyed to the sheet forming unit 80.

In the transport path of the mesh belt 72, the humidifying section 212 supplies air containing mist to the downstream side of the deposition section 60. As a result, the mist generated by the humidifying section 212 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 manufacturing apparatus 100 is provided with a transport unit 79 that transports the second web W2 on the mesh belt 72 to the sheet forming unit 80. The transport unit 79 has, for example, a mesh belt 79a, a stretching roller 79b, and a suction mechanism 79c.

The suction mechanism 79c includes a blower (not shown), and generates an upward airflow on the mesh belt 79a by the suction force of the blower. This air flow sucks the second web W2. As a result, the second web W2 is separated from the mesh belt 72 and adsorbed to the mesh belt 79a. The mesh belt 79a moves by the rotation of the stretching roller 79b, and conveys the second web W2 to the sheet forming unit 80. The moving speed of the mesh belt 72 and the moving speed of the mesh belt 79a are, for example, the same. In this way, the transport unit 79 peels the second web W2 formed on the mesh belt 72 from the mesh belt 72 and transports it.

The sheet forming unit 80 forms the sheet S from the deposits deposited by the depositing unit 60. More specifically, the sheet forming unit 80 pressurizes and heats the second web W2 accumulated on the mesh belt 72 and conveyed by the conveying unit 79 to form the sheet S. In the sheet forming unit 80, heat is applied to the fibers of the defibrated material included in the second web W2 and the additive, so that the plurality of fibers in the mixture are bound to each other via the additive (resin). ..

The sheet forming unit 80 includes a pressing unit 82 that presses the second web W2, and a heating unit 84 that heats the second web W2 pressed by the pressing unit 82.
The pressurizing unit 82 includes a pair of calender rollers 85, and presses the second web W2 by sandwiching it with a predetermined nip pressure. The thickness of the second web W2 is reduced by being pressed, and the density of the second web W2 is increased. One of the pair of calender rollers 85 is a drive roller driven by a pressure unit drive motor (not shown), and the other is a driven roller. The calendar roller 85 conveys the second web W<b>2, which has a high density due to the pressure, toward the heating unit 84.

The heating unit 84 can be configured using, for example, a heating roller (heater roller), a hot press molding machine, a hot plate, a warm air blower, an infrared heater, and a flash fixing device. In the present embodiment, the heating section 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 sandwiches the second web W2 pressed by the calender roller 85 and applies heat to form a sheet denoted by reference symbol S in FIG.
In this way, the second web W2 formed in the deposition unit 60 is pressed and heated in the sheet forming unit 80 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 unit 90.
The number of calender rollers 85 included in the pressing unit 82 and the number of heating rollers 86 included in the heating unit 84 are not particularly limited.

The cutting unit 90 (cutter unit) cuts the sheet S formed by the sheet forming unit 80. In the present embodiment, the cutting unit 90 cuts the sheet S in the direction parallel to the conveyance direction F, and the first cutting unit 92 that cuts the sheet S in the direction intersecting the conveyance direction of the sheet S indicated by the symbol F in the drawing. And a second cutting portion 94. The second cutting unit 94 cuts the sheet S that has passed through the first cutting unit 92, for example.

The cutting unit 90 forms a single-cut sheet S having a predetermined size. The cut single-cut sheet S is discharged to the sorting unit 95. The sorting unit 95 is a sorting mechanism that sorts and conveys the sheet S to each of the storage units 103.

In the above configuration, the crushing unit 12 first crushes the raw material and the sheet S is manufactured from the crushed raw material. However, for example, the sheet S may be manufactured by using the fiber as the raw material. Is also possible.
For example, the fiber which is equivalent to the defibrated material that has been defibrated by the defibrating unit 20 may be used as a raw material and can be put into the drum unit 41. Further, it is preferable that the same fiber as the first sorted material separated from the defibrated material is used as a raw material and can be put into the tube 54. In this case, the sheet S can be manufactured by supplying fibers obtained by processing used paper or pulp to the sheet manufacturing apparatus 100.

FIG. 3 is a schematic diagram showing the configuration of the housing portion 103.
The storage unit 103 has a storage unit main body 103H into which the sheets S are loaded from above and stacks and stores the sheets S, and separates the lowest sheet S′ one by one and conveys it to the guide 103G. The guide 103G forms a conveyance path between the accommodation unit 103 and the printing apparatus 105.
The housing body 103H includes a bottom plate portion 103T (bottom wall portion) on which the sheets S are stacked and placed, and a wall portion 103K (side wall portion) rising from the periphery of the bottom plate portion 103T. The wall portion 103K is provided with a discharge port 103W for discharging the lowest sheet S toward the guide 103G. In addition, a roller 103R that comes into contact with the lowest sheet S'from below is provided.

Each roller 103R of the 1st-3rd accommodating part 103A-103C is rotationally driven by the 1st-3rd accommodating part drive motor 343A-343C (FIG. 4), and the lowest sheet|seat S is sent out toward the guide 103G ( Discharge). The guide 103G is provided with a transport mechanism (not shown) for transporting the sheet S to the printing device 105, and the transport mechanism transports the sheet S to the printing device 105. When the accommodation unit 103 and the printing apparatus 105 are close to each other, the roller 103R alone may be used to convey the printing apparatus 105. Further, instead of the roller 103R, a belt may be used to feed the lowest sheet S.

In addition, the accommodation portion 103 includes a pressing member 103P that comes into contact with the uppermost sheet S in the accommodation portion main body 103H from above. The pressing member 103P is urged downward by an urging member 103S such as a spring, and presses the sheet S in the housing portion main body 103H toward the roller 103R. As a result, the lowest sheet S is held in contact with the roller 103R, and the sheet S can be appropriately fed by the roller 103R.

According to the accommodating portion 103, the sheets S can be discharged in the manufacturing order. That is, the accommodating portion 103 discharges the sheet S by a so-called FIFO (First In First Out). Further, it is possible to simultaneously supply the sheet S from the sheet manufacturing unit 101 to the accommodation unit 103 and discharge the sheet S from the accommodation unit 103. Therefore, it is possible to reduce the waiting time on the printing device 105 side until the sheet S is supplied to the printing device 105.

FIG. 4 is a block diagram showing the configuration of the control system of the sheet manufacturing apparatus 100.
The sheet manufacturing apparatus 100 includes a control device 110 having a main processor 111 that controls each unit of the sheet manufacturing apparatus 100.
The control device 110 includes a main processor 111, a ROM (Read Only Memory) 112, and a RAM (Random Access Memory) 113. The main processor 111 is an arithmetic processing unit such as a CPU (Central Processing Unit), and controls each part of the sheet manufacturing apparatus 100 by executing a basic control program stored in the ROM 112. The main processor 111 may be configured as a system chip including peripheral circuits such as the ROM 112 and the RAM 113 and other IP cores.

The ROM 112 stores the program executed by the main processor 111 in a nonvolatile manner. The RAM 113 forms a work area used by the main processor 111, and temporarily stores a program executed by the main processor 111 and data to be processed.

The non-volatile storage unit 120 stores programs executed by the main processor 111 and data processed by the main processor 111. The non-volatile storage unit 120 stores, for example, setting data 121 and display data 122. The setting data 121 includes data for setting the operation of the sheet manufacturing apparatus 100. For example, the setting data 121 includes data such as characteristics of various sensors included in the sheet manufacturing apparatus 100 and threshold values used in the process of the main processor 111 detecting an abnormality based on detection values of the various sensors.

Further, the setting data 121 includes manufacturing start date and time (schedule) set by an operator who operates the sheet manufacturing apparatus 100, manufacturing conditions (density (basis weight) of the sheet S, shape (size, thickness), color, manufacturing amount. (Manufacturing number) etc.) and information for specifying each of the distribution conditions of the distribution unit 95.
As the sorting condition, sorting based on the type of the sheet S (basis weight, size, thickness, or color), sorting based on the printing order of the sheet S, or the like is applied. In the case of sorting based on the type of the sheet S, for example, among the A4 size sheets S, the sheet S having a grammage value A is stored in the first storage portion 103A, and the sheet S having a grammage value B is stored in the first storage unit 103A. The sheet S having the grammage value C is stored in the third storage portion 103C.

Here, it is conceivable that the printing apparatus 105 may want to print a book bound by using sheets S having different grammage or colors for the cover and the contents. In such a case, it is conceivable to set the sorting based on the printing order of the sheet S. For example, the sheets S are manufactured in the page order (printing order) of a bookbinding and housed in the specific housing section 103 in the manufacturing order (=page order). Then, the sheets S accommodated in the specific accommodation unit 103 are sequentially supplied to the printing apparatus 105 in the manufacturing order, so that the printing can be performed in the page order of bookbinding. The distribution condition is not limited to the above and may be set appropriately.
The setting data 121 also includes information on the set remaining amount that defines the minimum remaining amount of each accommodation unit 103. The value of the set remaining amount is, for example, information set by an operator who operates the sheet manufacturing apparatus 100. The value of the set remaining amount is information used in “automatic sheet replenishment control” shown in FIG. 6 described later.

The display data 122 is screen data displayed by the main processor 111 on the display panel 116 (FIG. 4). The display data 122 is, for example, data for displaying an operating state of the sheet manufacturing apparatus 100, various set values, a warning display, and the like. The display data 122 may be fixed image data, or may be data for setting a screen display for displaying data generated or acquired by the main processor 111.

The touch sensor 117 detects a touch (contact) operation or a pressing operation. The touch sensor 117 is composed of, for example, a pressure sensing type or a capacitance type sensor having a transparent electrode, and is arranged so as to overlap the display surface of the display panel 116. When detecting an operation, the touch sensor 117 outputs operation data including an operation position and the number of operation positions to the main processor 111. The main processor 111 detects an operation on the display panel 116 based on the output of the touch sensor 117 and acquires the operation position. The main processor 111 implements a GUI (Graphical User Interface) operation based on the operation position detected by the touch sensor 117 and the display data 122 being displayed on the display panel 116.

The control device 110 is connected to a sensor installed in each part of the sheet manufacturing apparatus 100 via a sensor I/F (Interface) 114. The sensor I/F 114 is an interface that acquires a detection value output by the sensor and inputs the detection value to the main processor 111. The sensor I/F 114 may include an A/D (Analog/Digital) converter that converts an analog signal output by the sensor into digital data. Further, the sensor I/F 114 may supply a drive current to each sensor. Further, the sensor I/F 114 may include a circuit that acquires the output value of each sensor according to the sampling frequency specified by the main processor 111 and outputs the output value to the main processor 111.

The sensor I/F 114 is connected with a used paper remaining amount sensor 301, a first accommodation portion remaining amount sensor 303A, a second accommodation portion remaining amount sensor 303B, and a third accommodation portion remaining amount sensor 303C.
The used paper remaining amount sensor 301 detects the remaining amount of used paper that is the raw material of the sheet S. The used paper remaining amount sensor 301 notifies the shortage of used paper when the detected remaining amount of used paper falls below a set value.
The first accommodation portion remaining amount sensor 303A detects the amount of the sheets S accommodated in the first accommodation portion 103A. Further, the second accommodation portion remaining amount sensor 303B detects the amount of the sheets S accommodated in the second accommodation portion 103B. In addition, the third accommodation portion remaining amount sensor 303C detects the amount of the sheets S accommodated in the third accommodation portion 103C. Hereinafter, when it is not necessary to distinguish between the first to third accommodating section remaining amount sensors 303A to 303C, they are referred to as accommodating section remaining amount sensors 303.

The control device 110 gives a notification when the amount (remaining amount) of the sheet S detected by each accommodation unit remaining amount sensor 303 reaches a predetermined amount. Also, the control device 110 automatically manufactures and replenishes the sheet S of the type stored in the storage section 103, which has become less than the set remaining amount, into the storage section 103 (see " Automatic sheet replenishment control”) is executed.

The above configuration is an example, and for example, the sheet manufacturing apparatus 100 may include other sensors, and the control device 110 may be able to acquire the detection values of these sensors. For example, the sheet manufacturing apparatus 100 includes a sensor that detects the remaining amount of the additive in the additive supply unit 52, a sensor that detects the amount of water in a tank (not shown) in which the sheet manufacturing apparatus 100 stores humidifying water, and the like. May be. Further, the sheet manufacturing apparatus 100 may include a sensor that detects the temperature, air volume, and wind speed of the air flowing inside the sheet manufacturing apparatus 100.

The control device 110 is connected to each drive unit included in the sheet manufacturing apparatus 100 via a drive unit I/F (Interface) 115. The drive unit included in the sheet manufacturing apparatus 100 is a motor, a pump, a heater, or the like.
In the drive unit I/F 115, the supply unit 10, the crushing unit 12, the defibration unit 20, the additive supply unit 52, the blower 315, the humidification unit 316, the drum drive unit 317, and the belt drive are controlled by the control device 110. The part 318 and the dividing part 319 are connected.
The supply unit 10 includes a drive unit such as a motor that rotates a roller (not shown) included in the supply unit 10. The defibrating unit 20 includes a drive unit such as a motor that rotates a rotor (not shown) included in the defibrating unit 20. The additive supply unit 52 includes a motor that drives a screw feeder that discharges the additive in the discharge unit 52a, and a drive unit such as a motor and an actuator that opens and closes the discharge unit 52a. The blower 315 includes a defibrating unit blower 26, a collection blower 28, a mixing blower 56, a suction blower 77, and the like. Each of these blowers may be individually connected to the drive unit I/F 115. The humidifying section 316 includes the humidifying sections 202, 204, 206, 208, 210, 212 and the like.

The drum driving unit 317 includes a driving unit such as a motor that rotates the drum unit 41. The belt drive unit 318 includes a drive unit such as a motor that drives the mesh belt 46 and a motor that drives the mesh belt 72.
The dividing unit 319 includes a driving unit such as a motor that rotates the rotating body 49. Further, a heater, a vaporization type humidifier, a mist type humidifier, etc. for heating the heating roller 86 may be connected to the drive unit I/F 115. Moreover, you may connect the water supply pump which supplies water to each humidifier to the drive part I/F115.

Further, the drive unit I/F 115 is connected to the pressurizing unit 82, the heating unit 84, the distribution unit 95, the first storage unit drive motor 343A, the second storage unit drive motor 343B, and the third storage unit drive motor 343C. It The first storage unit drive motor 343A drives the roller 103R of the first storage unit 103A. The second housing drive motor 343B drives the roller 103R of the second housing 103B. The third accommodation unit drive motor 343C drives the roller 103R of the third accommodation unit 103C. The control device 110 controls the start, stop, and rotation speed of the rotation of the first to third housing drive motors 343A to 343C. Hereinafter, when it is not necessary to distinguish between the first to third accommodation unit drive motors 343A to 343C, they are referred to as accommodation unit drive motors 343.

FIG. 5 is a flowchart showing the basic operation of the sheet manufacturing apparatus 100.
The control device 110 can start the operation shown in FIG. 5 after the power of the sheet manufacturing apparatus 100 is turned on and the start-up sequence is executed. As shown in FIG. 5, when the manufacturing instruction is input, or when the preset manufacturing start date and time is reached (step S1A; YES), the control device 110 starts manufacturing the sheet S (step S2A). ..

A manufacturing start instruction can be input to the control device 110 via the operation panel such as the touch sensor 117, and the manufacturing start date and time, manufacturing conditions, and the like can be set. The manufacturing conditions include the density (basis weight), shape (size, thickness), color, and manufacturing amount (number of manufactured sheets) of the sheet S.
Further, when the manufacturing instruction is not input or when the manufacturing start date and time has not been reached (step S1A; NO), the control device 110 temporarily ends the processing shown in FIG. 5 and executes the processing of step S1A with a time interval. To do. Alternatively, the process of step S2A and the subsequent steps may be executed by using the input of the manufacturing instruction as a trigger.

In step S2A, the control device 110 operates the respective parts of the sheet manufacturing unit 101 to manufacture the sheet S. In this case, the control device 110, for example, adjusts the speed V2 of the mesh belt 72 of the second web forming unit 70, adjusts the speed V1 of the mesh belt 46, and/or adjusts the amount of fibers to be lowered from the drum unit 61. By performing the above, the density of the sheet S is controlled. The control device 110 also controls the color of the sheet S by controlling the type and amount of the colorant added by the additive supply unit 52. Further, the control device 110 controls the size of the sheet S by the cutting unit 90 and controls the thickness of the sheet S by the pressing unit 82. Thereby, the sheet S according to the preset manufacturing conditions is manufactured.

The manufactured sheet S is discharged to the sorting unit 95. The control device 110 sorts the sheets S discharged to the sorting unit 95 into the storage units 103 according to preset sorting conditions (step S3A). As a result, the sheets S are stored in the storage units 103 for each type or printing order. Further, the control device 110 is provided with a counting sensor (not shown) that counts the sheets S, or a configuration that counts the number of times of cutting of the cutting unit 90 and the like, and can specify the manufacturing amount (number of manufactured sheets) of the sheets S.

Subsequently, the control device 110 determines whether or not the manufacturing of the sheet S is to be ended (step S4A), and when the manufacturing is to be ended, the operation of each part of the sheet manufacturing unit 101 is stopped (step S5A). The case of ending the production is, for example, the case where the production amount of the sheet S reaches the amount according to the production condition, the production stop is instructed through the touch sensor 117, or the production stop date and time is reached. .. As described above, the sheet S is manufactured so as to match the manufacturing conditions, and the manufactured sheet S is sorted and stored in each of the storage units 103 according to the sorting condition. The above is the basic operation of the sheet manufacturing apparatus 100.

The control device 110 can execute “automatic sheet replenishment control” that controls the type of the sheet S to be manufactured according to the remaining amount of the sheet S stored in each storage unit 103.
FIG. 6 is a flowchart showing the automatic sheet replenishment control.
The control device 110 can start the operation shown in FIG. 6 after the power of the sheet manufacturing apparatus 100 is turned on and the start-up sequence is executed. As shown in FIG. 6, the control device 110 determines whether or not the remaining amount of each accommodation unit 103 is less than a preset remaining amount based on the remaining amount detected by each accommodation unit remaining amount sensor 303. (Step S1B). The set remaining amount may be the same or different in the first to third accommodating portions 103A to 103C.

When the remaining amount of any of the accommodation units 103 is less than the set remaining amount (step S1B; YES), the control device 110 identifies the type of the sheet S corresponding to the accommodation unit 103 that does not satisfy the set remaining amount, and the sheet S The production amount of S is specified (step S2B).
The specification of the type of the sheet S in this case is to specify the information other than the production amount in the manufacturing conditions of the sheet S. For example, the sorting condition of the sheet S is referred to, and the shortage of the sheets S To specify density, shape, color, etc. In addition, the specification of the production amount of the sheet S is to specify a value that makes the remaining amount of the accommodation unit 103 exceed the set remaining amount, and for example, the remaining amount detected by the accommodation unit remaining amount sensor 303. Based on the above, the value (the number of sheets) that satisfies the set remaining amount is set. In this way, the manufacturing conditions of the sheet S to be manufactured are set.
Further, when there are a plurality of accommodation units 103 that do not satisfy the set remaining amount, the manufacturing conditions of the sheet S are set for each accommodation unit 103.

Next, the control device 110 starts manufacturing the sheet S according to the specified manufacturing conditions (step S3B). When there are a plurality of accommodation units 103 that do not satisfy the set remaining amount, the production of the sheet S corresponding to any one of the accommodation units 103 is started, and after the production is completed, the sheets corresponding to the other accommodation units 103 are completed. Production of S begins. For example, the manufacturing of the sheet S of the type corresponding to the accommodation unit 103 having a large shortage with respect to the set remaining amount is started. Alternatively, the manufacturing of the sheet S of the type corresponding to the preset priority is started. As a result, it is possible to suppress a situation in which a plurality of types of sheets S are collectively manufactured for each sheet of the same type and the manufacturing conditions frequently change during manufacturing.
On the other hand, when the control device 110 determines in step S1B that all the storage units 103 satisfy the set remaining amounts (step S1B; NO), the process illustrated in FIG. 6 is ended, and a time interval is added to step S1B. Execute the process.

In step S3B, the control device 110 controls each part of the sheet manufacturing unit 101 to manufacture the sheet S according to the manufacturing conditions, as in step S2A. Further, the control device 110 sorts the manufactured sheets S into the corresponding storage portions 103 according to the sorting conditions and stores them (step S4B).

Subsequently, the control device 110 determines whether or not the manufacturing of the sheet S is to be ended (step S5B), and when the manufacturing is to be ended, the operation of each part of the sheet manufacturing unit 101 is stopped (step S6B). The case where the production is ended is the case where the production amount of the sheet S reaches the target amount. As described above, when the remaining amount of any of the accommodation units 103 becomes less than the set remaining amount, the sheet S accommodated in the accommodation unit 103 is automatically manufactured and accommodated in the accommodation unit 103.

It should be noted that the set remaining amount may be a value common to each of the storage units 103 or may be a different value. For example, when the sheet S, which is considered to be frequently used, is stored in the first storage unit 103A, the set remaining amount corresponding to the first storage unit 103A is larger than the set remaining amount corresponding to the other storage units 103B and 103C. It is possible to set it to a value.
In this case, if the accommodable capacities of the respective accommodating portions 103 are the same, if the paper is used evenly from the full state, the remaining amount of the sheets S accommodated in the first accommodating portion 103A is first set to the remaining amount. This is less than the limit, and the sheets S accommodated in the first accommodating portion 103A can be preferentially manufactured. The above is the automatic sheet replenishment control.

FIG. 7 is a flowchart showing the basic operation of the printing device 105.
The control unit 105A of the printing apparatus 105 can start the operation illustrated in FIG. 7 after the power of the printing apparatus 105 is turned on and the activation sequence is executed.
When the print data is input (received), the control unit 105A determines whether the supply destination of the sheet to be printed is the sheet manufacturing apparatus 100 (storage unit 103) or the fourth storage unit 104 (step S2C).
Here, in determining whether the supply destination of the sheet to be printed is the accommodation unit 103 or the fourth accommodation unit 104, information indicating the supply destination of the sheet is included in the print data, and the control unit 105A based on the information. May be applied. Alternatively, a method in which the control unit 105A makes a determination based on the sheet information (for example, the size) of the print target included in the print data may be applied. The print data includes the content of general print data, that is, the print content, the type (for example, size) of the sheet S to be printed, and the print amount (the number of printed sheets).

When the sheet supply destination is the sheet manufacturing apparatus 100 (accommodation unit 103) (step S2C; YES), the control unit 105A can specify the print target sheet S and the print amount (the number of prints) included in the print data. The information is transmitted to the sheet manufacturing apparatus 100 as print target information (step S3C). After that, when the sheet S is supplied from the sheet manufacturing apparatus 100 (step S4C; YES), the control unit 105A starts printing on the sheet S (step S5C). As a result, an image based on the print data is printed on the sheet S manufactured by the sheet manufacturing apparatus 100.

On the other hand, when the sheet S is not supplied (step S4C; NO), the control unit 105A waits until the sheet S is supplied. However, it is preferable to execute a predetermined notification process when the waiting time exceeds a preset allowable time. For example, if the sheet manufacturing apparatus 100 cannot manufacture the sheet S to be printed due to a shortage of used paper or the like, the notification process is executed at a timing when the standby time exceeds the allowable time. An appropriate time may be set as the allowable time.

When it is determined in step S2C that the sheet supply destination is the fourth container 104 (step S2C; NO), the controller 105A requests the fourth container 104 for a sheet to be printed (step S10C). , The process proceeds to step S4C. Therefore, when the sheet is supplied from the fourth container 104 (step S4C; YES), the controller 105A starts printing on the sheet (step S5C). When printing a plurality of sheets continuously, the printing process is repeated for each sheet (steps S4C and S5C).

After starting the printing, the control unit 105A determines whether or not the printing is to be ended (step S6C), and when the printing is to be ended, the operation of each unit of the printing apparatus 105 is stopped (step S7C). The case of ending the printing is, for example, the case of completing all the printing based on the print data. In this way, the printing apparatus 105 can print using the sheet S manufactured by the sheet manufacturing apparatus 100 or the sheet stored in the fourth storage unit 104.
The fourth accommodating unit 104 may be a paper feeder built in the printing apparatus 105 or a paper feeder externally connected to the printing apparatus 105.
Further, in step S1C, when the control device 110 does not input the print data (step S1C; NO), the process shown in FIG. 7 is ended, and the process of step S1C is executed with a time interval. Alternatively, the input of print data may be used as a trigger to execute the processing from step S2C.

FIG. 8 is a flowchart showing the operation of the sheet manufacturing apparatus 100 when the print target information (step S3C in FIG. 7) is acquired from the printing apparatus 105.
As illustrated in FIG. 8, when the control device 110 inputs (receives) print target information (step S1D; YES), the control unit 110 determines whether to print the sheet S based on the print target sheet S and the print amount specified by the print target information. It is determined whether manufacturing is necessary (step S2D).

Whether or not the sheet S needs to be manufactured is determined based on the remaining amount of the containing portion 103.
Specifically, the control device 110 determines that the manufacturing of the sheet S is unnecessary when the sheet S to be printed is stored in any one of the storage units 103 in the print amount or more (step S2D; NO).
In this case, the control device 110 starts control of feeding the sheet S to be printed, which is stored in the storage unit 103, to the printing device 105 (step S3D). Next, the control device 110 determines whether or not to finish feeding the paper (step S4D). When the control unit 105A supplies the printing target sheet S to the printing apparatus 105 by the printing amount, it determines that the feeding is ended (step S4D; YES), and stops the feeding (step S5D).

In step S2D, the control device 110 needs to manufacture the sheet S when the remaining amount of the accommodation unit 103 of the accommodation units 103 in which the sheet S to be printed is accommodated is small (when the printing amount is not satisfied). (Step S2D; YES). Further, the control device 110 determines that the production of the sheet S is necessary even when the sheet S to be printed is not accommodated in all the accommodating portions 103 (step S2D; YES).

However, even if the sheet S to be printed is not accommodated in all the accommodating portions 103, if another sheet S is accommodated in all the accommodating portions 103, even if the sheet S to be printed is manufactured, It is difficult to immediately supply the sheet S to the printing apparatus 105 from each accommodation unit 103. Therefore, when the sheet S to be printed is not accommodated in any of the accommodating sections 103 and the two accommodating sections 103 are empty, the control device 110 It is preferable to determine that the sheet S needs to be manufactured.
In addition, when the condition that one of the accommodation units 103 is empty is not satisfied, it is preferable that the control device 110 perform a notification process that prompts the user to empty any of the accommodation units 103. Then, when any of the accommodating portions 103 becomes empty, the control device 110 may shift to the process of step S6D described later.

When determining that the production of the sheet S is necessary (step S2D; YES), the control device 110 shifts to the processing of step S6D, specifies the insufficient sheet S as the sheet to be produced, and secures the insufficient number of sheets. Specify the production volume. The target production amount may be the same as the number of deficient sheets, or may be set to a number larger than the number of deficient sheets.
Next, the control device 110 starts the production of the sheet S to be produced (step S7D), and distributes the produced sheet S to the accommodating portions 103 according to the distribution conditions (step S8D). As a result, the manufactured sheet S is stored in the storage unit 103 that should store the sheet S to be printed.

In addition, the control device 110 starts the control of feeding the sheet S to be printed to the printing device 105 via the containing portion 103 (step S9D). In the present configuration, as shown in FIG. 3, the accommodation unit 103 ejects the sheet S by the FIFO, so that the sheet S can be supplied to and ejected from the accommodation unit 103 at the same time, and the manufactured sheet S can be quickly ejected. Can be supplied to the printing device 105. Therefore, it is possible to reduce the waiting time for printing, and there is no need for complicated control for controlling the supply and discharge of the sheet S at different timings.

Subsequently, the control device 110 determines whether or not the manufacturing of the sheet 2 is to be ended (step S10D), and when the manufacturing is to be ended, the operation of each part of the sheet manufacturing unit 101 is stopped (step S11D). The case of ending the production is, for example, the case where the production amount of the sheet S reaches the target production amount.
Further, the control device 110 determines whether or not to finish feeding the sheet 2 (step S12D), and when the feeding is finished, stops the operation of the accommodating unit 103 and stops the feeding (step S13D). ). The case of ending the sheet feeding is a case where the number of sheets S corresponding to the printing amount is supplied to the printing apparatus 105. As described above, when the sheet S to be printed is insufficient, the insufficient sheet S is manufactured and can be fed to the printing apparatus 105.

As described above, the sheet manufacturing apparatus 100 according to the present embodiment distributes the manufactured sheet S to the sheet manufacturing unit 101 that manufactures a plurality of types of sheets S under the predetermined conditions by the sorting unit 95, and stacks the sheets by type. And a plurality of accommodating portions 103 for accommodating. The sheet manufacturing apparatus 100 also includes a roller 103R (sheet feeding unit) that feeds the lowest sheet stored in each of the storage units 103. Then, the control device 110 of the sheet manufacturing apparatus 100 drives the roller 103R so as to feed out the sheet S to be fed among the lowest sheets S stored in the storage portions 103. The control device 110 can be regarded as a part of the sheet feeding unit.

According to this configuration, the manufactured sheets S can be sorted and stored in the plurality of storage units 103 according to various criteria such as the type or the printing order, and the manufactured sheets S can be stored according to the side on which they are used. is there. Accordingly, various sheets S accommodated in the accommodating portion can be immediately supplied to the printing apparatus 105, and the waiting time for printing can be reduced.

In addition, it is preferable that the sheet manufacturing apparatus 100 is installed in an office or the like where used paper that is suitable as a raw material of the sheet S is generated and the sheet S is used. This makes it possible to perform recyclable printing and paper recycling in the office.
Further, since various sheets S are stored in the respective storage portions 103, the manufacturing time of the sheets S is less likely to be restricted by the usage time of the sheets S (time zone of printing). For example, when the sheet manufacturing apparatus 100 is installed in an office, the sheet S is manufactured during a time period when there are few people in the surroundings, and a sufficient number of sheets S are provided during a time period when there are many people (a time zone where many prints are made). It can be supplied to the printing apparatus 105. It is also possible to manufacture the sheet S and store it in each of the storage units 103 during a time when the electricity rate is low.

In addition, since each accommodation unit 103 discharges the sheet S by a so-called FIFO, the sheet S is discharged in the manufacturing order, and the old sheet S does not remain. Moreover, since the sheet S can be supplied to and discharged from the storage unit 103 at the same time, complicated control is unnecessary and the waiting time for printing can be reduced.

Further, the sheet manufacturing unit 101 can manufacture the sheets S having different density (basis weight), size, and/or color. This makes it easier to meet the demands of the side using the sheet S.
Further, the raw material of the sheet S may not be particularly limited as long as it can be manufactured. Further, the supply unit 10 may have a configuration capable of supplying various raw materials so that the sheet manufacturing unit 101 can manufacture sheets S having different raw materials. As a result, the sheet 2 can be manufactured with a raw material (raw material) that meets the needs of the side using the sheet S.

The sheet manufacturing unit 101 also includes a defibrating unit 20 that defibrates the crushed raw material in air, and a web forming unit that deposits defibrated material defibrated by the defibrating unit 20 to form a web. 45 and 70, and a sheet forming unit 80 that forms the sheet S from the web. As a result, the sheet manufacturing unit 101 is configured as a dry type, and compared to a case where the sheet manufacturing unit 101 is configured as a so-called wet type, water-related equipment can be unnecessary or simplified, and it is suitable for installation in an office or the like.

Further, the sheet manufacturing system 1 includes a sheet manufacturing apparatus 100 and a printing apparatus 105 (printing section) that prints on the sheet S fed from each accommodation section 103 of the sheet manufacturing apparatus 100. As a result, as described above, the waiting time for printing is reduced, the situation in which the sheet S having an old manufacturing history remains is suppressed, and the sheet manufacturing system 1 that can easily respond to the request of the side using the sheet S is provided. it can.

Further, the printing device 105 of the sheet manufacturing system 1 may be appropriately changed within a range in which the number of the printing devices 105 is smaller than that of the plurality of storage units 103. According to this configuration, various sheets S accommodated in the plurality of accommodating portions 103 can be printed by the small number of printing devices 105, and the sheet manufacturing system 1 can be easily made compact. This is also suitable for installation in an office or the like. When the installation space is not restricted, the number of printing devices 105 may be the same as or larger than the number of storage units 103.

In addition, although the case where the manufactured sheet S is used for printing is illustrated in the present embodiment, it may be used for other than printing. When used for other than printing, another device that uses the sheet S may be provided instead of the printing device 105 or in addition to the printing device 105. When another device is provided, the basic operation of the device may be similar to the flowchart shown in FIG. 7. For example, in step S3C shown in FIG. 7, information (use target information) that specifies the use target sheet S and the use amount (use number) is transmitted to the sheet manufacturing apparatus 100, and in steps S5C to S7C, printing is replaced. You can start and stop using it.

Further, as shown in FIG. 6, the sheet manufacturing apparatus 100 of the present embodiment determines the type of the sheet S manufactured by the sheet manufacturing unit 101 based on the remaining amount of the sheets S stored in the plurality of storage units 103. The control device 110 for controlling is provided. According to this configuration, various sheets S can be stored in the plurality of storage portions 103 with a sufficient remaining amount. Therefore, various sheets S can be used (printed) promptly, and the sheets S to be used can be preferentially automatically replenished. As a result, restrictions on the use of the manufactured sheet S can be reduced, and in particular, the waiting time until the use can be reduced.

Moreover, as shown in FIG. 8, the control device 110 determines the type of the sheet S manufactured by the sheet manufacturing unit 101 based on the print target information (use target information) that is information that can specify the printing of the sheet S. Control. Accordingly, the sheet S to be printed can be easily specified, and the sheet S consumed by printing can be preferentially automatically replenished.
Further, the control device 110 specifies the print amount based on the print target information, and controls the production amount of the sheet manufacturing unit 101 based on the print amount. As a result, the sheet S can be manufactured in an amount corresponding to the printing amount, and the appropriate amount can be automatically replenished.

As a result, for example, when printing a larger number of sheets than the number of sheets accommodated in the accommodating unit 103, the production of the sheets S can be started at an early stage, and the shortage of the sheets S used for printing can be easily resolved. This makes it possible to efficiently reduce the waiting time until printing. Further, since the print target information is obtained from the print data to the printing apparatus 105, the print target sheet S and the print amount can be accurately specified.

Note that the sheet manufacturing system 1 is configured to be capable of accepting an interrupt from a user-side device such as interrupt printing from the printing device 105 or an interrupt from an operator who operates the sheet manufacturing device 100 or the printing device 105. Good. When the interrupt is accepted, the interrupt may be input as information that can specify the use of the sheet S, and the type of the sheet S manufactured by the sheet manufacturing unit 101 may be controlled based on this information. Specifically, the operation in which step S1D of the flowchart shown in FIG. 8 is a process of determining whether or not an interrupt is accepted may be executed.

In general, when an interruption occurs, it is considered that the priority is high, and thus the sheet S having the high priority can be preferentially automatically replenished. Here, the information (use side identification information) input to the control device 110 when an interruption occurs includes information indicating interruption printing and information that can identify the type and usage amount of the sheet S to be printed. It is preferable. With this configuration, the type and amount of the sheet S used for interruption can be specified, and appropriate manufacturing can be facilitated.

Further, when the sheet S accommodated in any of the accommodating units 103 does not satisfy the set remaining amount (predetermined remaining amount), the control device 110 manufactures the sheet S that does not satisfy the set remaining amount in the sheet manufacturing unit 101. Let As a result, the sheets S with a small remaining amount can be preferentially automatically replenished.

(Second embodiment)
FIG. 9 is a diagram showing a sheet manufacturing system 1 according to the second embodiment. In the following description, the same parts as those in the first embodiment will be designated by the same reference numerals, description thereof will be omitted, and different parts will be described.
This sheet manufacturing system 1 has a take-out containing section 103D for containing a predetermined sheet S manufactured by the sheet manufacturing section 101 so that the user can take it out. The user can take out the sheet S from the take-out accommodating section 103D and set it in an arbitrary printing device or the like for use.
For example, when the sheet manufacturing system 1 is placed in an office, the printing device exists at a position apart from the sheet manufacturing system 1. By providing the take-out accommodating portion 103D, various users can use the recycled sheet S in a printing device existing at a distant position, and the utilization of the sheet S can be promoted.

The take-out accommodating portion 103D having this configuration is not connected to the printing apparatus 105 in the sheet manufacturing system 1, but is configured as a take-out stacker. The storage unit 103D for taking out may have the same configuration as the other storage units 103A to 103C or may have a different configuration. The take-out accommodating section 103D may also be connected to the printing device 105. In this configuration, a take-out accommodating portion remaining amount sensor 303D that detects the amount of sheets S accommodated in the take-out accommodating portion 103D is provided, and the control device 110 causes the take-out accommodating portion 103D based on the detection result of the sensor 303D. It is configured to be able to detect the remaining amount of sheets inside.

In the sheet manufacturing system 1, since the sheets S stored in the take-out storing portion 103D are used for printing by a large number of printing devices, the sheets S are likely to be emptied in a relatively short period of time.
Therefore, the control device 110 executes the automatic replenishment control of the sheet shown in FIG. 6 only for the take-out accommodating section 103D that is a specific accommodating section. That is, in step S1B shown in FIG. 6, the control device 110 determines whether or not the remaining amount of the take-out accommodating section 103D is less than a preset remaining amount based on the detection result of the take-out accommodating section remaining amount sensor 303D. judge. As a result, when the remaining amount of the take-out accommodating portion 103D becomes less than the set remaining amount, the sheet S accommodated in the take-out accommodating portion 103D is manufactured and automatically replenished.

The control shown in FIG. 6 is not performed for the other accommodation units 103A to 103C, and the administrator or the like who manages the sheet manufacturing system 1 appropriately manufactures the sheets S to be accommodated in the other accommodation units 103A to 103C. Let
In this way, it is possible to efficiently avoid the situation where the remaining amount of the specific accommodation section (accommodation section 103D for extraction) becomes empty. Note that the specific accommodation unit is not limited to the extraction accommodation unit 103D, and may be other accommodation units 103A to 103C, or the plurality of accommodation units 103 may be specified accommodation units.

(Third Embodiment)
The third embodiment is different from the first embodiment in that the sheet manufacturing unit 101 is an electrostatic type.
FIG. 10 is a schematic diagram showing a main part of the sheet manufacturing unit 101 of the third embodiment.
The sheet manufacturing unit 101 performs a post-treatment to electrostatically transfer the fiber-containing material as a raw material onto the conveyor belt 401 (transfer target) and adjust the surface properties so as to appropriately form an ink receiving layer on the fiber-containing material. Thus, the sheet S is manufactured.
The sheet manufacturing unit 101 includes a supply unit 410 that supplies a fiber-containing material, a carrier 420 (second carrier) that supports the supplied fiber-containing material, and a conveyor belt to which the carried fiber-containing material is electrostatically transferred. It has 401 and the post-processing part 430 which performs post-processing.

In the sheet manufacturing unit 101, the fiber-containing material is electrostatically transferred from the carrier 420 to the transfer target (conveying belt 401). Accordingly, it is possible to prevent variations in the amount of the fiber-containing material attached to the transfer target (conveying belt 401), that is, the fiber-containing material adheres to the transfer target (conveying belt 401) without excess or deficiency. As a result, the sheet S obtained from the fiber-containing material can be stably manufactured with a uniform thickness.

The fiber-containing material used as a raw material is composed of a composite containing cellulose fibers and a hydrophobic material that covers at least a part of the cellulose fibers, and is heated under pressure by the post-treatment unit 430 to receive ink. A layer is formed.
Cellulose fibers may be derived from cellulosic products such as used paper or virgin pulp, and fibers containing cellulose are widely applicable. For example, cellulose fibers obtained by defibrating waste paper can be used.

The hydrophobic material binds the cellulose fibers together to form a porous ink receiving layer. The hydrophobic material adjusts the balance between hydrophobicity and hydrophilicity of the ink receiving layer, suppresses excessive wetting and spreading of the ink when the ink is applied to the sheet S, and has excellent ink absorbability. Becomes In addition, the hydrophobic material coats the cellulose fibers and stabilizes the charging properties of the composite. Thereby, the ink receiving layer can be preferably formed by electrostatic coating. As the hydrophobic material, for example, a thermoplastic resin or a curable resin can be used.
Further, the hydrophobic material may include 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. 10, the supply unit 410 stores a storage unit 412, a stirrer 413 (agitator), a roller 414, a first carrier 415, and a blade 416 in a housing unit 411.
The storage section 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 section 412, and charges the fiber-containing material by friction during stirring. This fiber-containing material is supplied to the first carrier 415 by the rotation of the roller 414. The first carrier 415 has a potential difference with the roller 414, and the fiber-containing material is electrostatically attached. The blade 416 adjusts the thickness (adhesion amount) of the fiber-containing material attached to the first carrier 415 to adjust the thickness of the sheet to a predetermined thickness (thin film), and electrically charges the fiber-containing material by friction.

The carrier 420 has a potential difference between the carrier 420 and the first carrier 415, and the fiber-containing material electrostatically adheres to the carrier 420. The carrier 420 is a rotating roller member, and transfers the fiber-containing material carried on the carrier 420 to the conveyor belt 401.
Around the carrier 420, a charging unit 422 that charges the outer peripheral surface 421 of the carrier 420 and an exposure unit 423 that adjusts the potential of the outer peripheral surface 421 are provided. Further, around the carrier 420, a transfer unit 424 that transfers the fiber-containing material to the conveyor belt 401 by an electrostatic force generated by a potential difference between the carrier 420 and the carrier 420 is provided.

Further, the transfer unit 424 pressurizes the fiber-containing material transferred onto the conveyor belt 401 between the carrier 420 and the carrier 420 to make the thickness of the fiber-containing material uniform and adjust the ink receiving layer to have a uniform thickness.
The conveyor belt 401 is an endless belt, and is conveyed by a plurality of rollers 402. The surface of the conveyor belt 401 to which the fiber-containing material is transferred is preferably made of a resin having medium/high resistance (volume resistivity 107 to 1011 Ω·cm). Such a constituent material is not particularly limited, and for example, a material in which carbon black is kneaded in a fluororesin can be used. As a result, the powder of the fiber-containing material is transferred to the conveyor belt 401 due to the potential difference, and electrostatically held on the conveyor belt 401 more easily.

The post-processing unit 430 includes a leveling processing unit 431 that smoothes the surface of the fiber-containing material transferred onto the conveyor belt 401, a pressure processing unit 432 that presses the fiber-containing material, and a semi-solidifying surface of the fiber-containing material. The solidification processing unit 433 and the ink receiving layer solidifying unit 434 that solidifies the ink receiving layer formed of the layered fiber-containing material are provided. The leveling processing unit 431 has a leveling roller 435 of which at least the outer peripheral surface is a metal surface, smoothes the surface of the fiber-containing material by the leveling roller 435, and at the same time with respect to the fiber-containing material via the ground wire 436. Remove electricity.

The pressure processing unit 432 bonds the fiber-containing materials to each other by the pressure applied by the pressure roller 437 to make the density uniform. The semi-solidification processing unit 433 has a chamber 438 made of a heat insulating material and a heater 439 provided in the chamber 438, and semi-solidifies the surface of the fiber-containing material by heating with the heater 439.

The ink receiving layer solidifying section 434 includes a solidifying roller 440 and a heater 441 provided in the solidifying roller 440. The solidifying roller 440 is heated by energizing the heater 441, and the solidifying roller 440 heats the ink receiving layer. Meanwhile, the ink receiving layer is pressed in the direction of decreasing the layer thickness. As a result, the thermoplastic resin in the ink receiving layer is melted, and after the molten thermoplastic resin has passed through the solidifying roller 440, it is naturally cooled, bound, and solidified. In this way, the fiber-containing material, that is, the sheet S, having the ink receiving layer solidified without excess or deficiency, that is, the sheet S is manufactured.
A blower fan (not shown), a cutting unit 90 (not shown), a sorting unit 95 (not shown), and the like are provided downstream of the post-processing unit 430 to promote separation of the sheet S from the transport belt 401.

Compared with the sheet manufacturing unit 101 of the first embodiment, the sheet manufacturing unit 101 does not require defibration, selection, suction, web formation, etc., and therefore the sheet S manufacturing time can be shortened easily. Therefore, when the control or the like shown in FIG. 6 or FIG. 8 is executed, it becomes easier to reduce the waiting time required until the manufactured sheet S is used (printed). Therefore, it becomes easier to further reduce restrictions on the use of the manufactured sheet S.
Also, like the first embodiment, this sheet manufacturing unit 101 is also a dry type that does not use water as much as possible, so that water-related equipment can be eliminated or simplified, and it is suitable for installation in an office or the like.

It should be noted that each of the above-described embodiments is merely a specific mode for carrying out the present invention described in the claims, does not limit the present invention, and all the configurations described in the respective embodiments are the present invention. It is not limited to be an essential configuration requirement of. Further, the present invention is not limited to the configuration of each embodiment, and can be implemented in various modes without departing from the gist thereof.

Further, the sheet manufacturing apparatus 100 is not limited to the sheet S, and may be configured to manufacture a board-shaped or web-shaped product made of a hard sheet or laminated sheets. Further, the property of the sheet S is not particularly limited, and may be paper that can be used as recording paper for writing or printing (for example, so-called PPC paper), wallpaper, wrapping paper, colored paper, drawing paper, Kent paper. And so on. When the sheet S is a non-woven fabric, it may be a general non-woven fabric as well as a fiber board, a tissue paper, a kitchen paper, a cleaner, a filter, a liquid absorbent, a sound absorber, a cushioning material, a mat, or the like.

Further, in each of the embodiments, the case where the dry type sheet manufacturing unit 101 is provided has been described, but the present invention is not limited to this. For example, you may make it have a sheet manufacturing part which manufactures a sheet by what is called a wet papermaking method which throws a fiber-containing raw material into water and disaggregates and re-fabricates a fiber.
Further, the use side device that uses the sheet S manufactured by the sheet manufacturing apparatus 100 is not limited to the printing device 105, and devices that can use the sheet S can be widely applied.

It is not limited to the configuration in which the specified hardware resource is arranged. The program to be executed may be stored in the non-volatile storage unit or another storage device (not shown).
