The fourth storage unit 104 enables sheet paper having a size different from that of the storage unit 103 or a sheet of the same size to be fed. The printing apparatus 105 is an ink jet printer, for example. The printing apparatus 105 may be an electrophotographic printing apparatus such as a laser printer.
In addition, the 4th accommodating part 104 is an option added suitably, and can be abbreviate | 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 deposition unit 60, a second web forming unit 70, A transport unit 79, a sheet forming unit 80, a cutting unit 90, and a 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 a space in which the raw material moves. Specific configurations of the humidifying units 202, 204, 206, 208, 210, and 212 are arbitrary, and include a steam humidifier, a vaporizing humidifier, a hot air vaporizing humidifier, an ultrasonic humidifier, and the like. .

  In the present embodiment, the humidifying units 202, 204, 206, and 208 are configured by a vaporization type or warm air vaporization type humidifier. That is, the humidifying units 202, 204, 206, 208 have a filter (not shown) that partially wets the water, and supplies humidified air with increased humidity by allowing air to pass through the filter. Further, the humidifying units 202, 204, 206, and 208 may include a heater (not shown) that effectively increases the humidity of the humidified air.

  Moreover, in this embodiment, the humidification part 210 and the humidification part 212 are comprised with an ultrasonic humidifier. In other words, the humidifying units 210 and 212 have a vibrating unit (not shown) that atomizes water and supplies mist generated by the vibrating unit.

  The supply unit 10 supplies raw materials to the crushing unit 12. The raw material from which the sheet manufacturing apparatus 100 manufactures a sheet may be anything as long as it contains fibers, and examples thereof include paper, pulp, pulp sheet, cloth including nonwoven fabric, and woven fabric. In the present embodiment, a configuration in which the sheet manufacturing apparatus 100 uses waste paper as a raw material is illustrated.

  The crushing unit 12 crushes the raw material supplied by the supply unit 10 with a crushing blade 14 to obtain a crushing piece (crushed material). The crushing blade 14 is a blade for crushing the raw material in the air (in the air) or the like. The crushing unit 12 includes a pair of crushing blades 14 that crush the raw materials and a driving unit that rotates the crushing blades 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 defibrating process in the defibrating unit 20. For example, the crushing unit 12 crushes the raw material into paper pieces having a size of 1 to several cm square or less.

  The crushing unit 12 has a chute (also referred to as a hopper) 9 that receives the crushing pieces that are crushed by the crushing blade 14 and fall. The chute 9 has, for example, a tapered shape whose width gradually narrows in the direction (advancing direction) of the coarse fragments, and functions as a guide portion that receives and collects the coarse fragments that diffuse under the coarse blade 14. . The chute 9 is connected to a tube 2 communicating with the defibrating unit 20, and the tube 2 forms a conveying path for conveying the raw material (crushed pieces) 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) through the tube 2 to the defibrating unit 20. As a result, the tube 2 functions as a discharge part for discharging the coarse fragments collected by the chute 9.

  Humidified air is supplied by the humidifying unit 202 to the chute 9 included in the crushing unit 12 or in the vicinity of the chute 9. Thereby, the phenomenon in which the coarsely crushed material crushed by the coarse pulverizing blade 14 is attracted to the chute 9 or the inner surface of the tube 2 by static electricity can be suppressed. Moreover, since the coarsely crushed material which the coarsely pulverized blade 14 crushed is transferred to the defibrating unit 20 together with humidified (high humidity) air, the effect of suppressing adhesion of the defibrated material in the defibrating unit 20 is achieved. Can also be expected. Moreover, the humidification part 202 is good also as a structure which supplies humidified air to the rough crushing blade 14, and neutralizes the raw material which the supply part 10 supplies.

  The defibrating unit 20 defibrates the crushed material that has been crushed by the crushing unit 12. More specifically, the defibrating unit 20 performs a defibrating process using the crushed pieces crushed by the crushing unit 12 as raw materials to generate a defibrated material. Here, “defibration” means unraveling a raw material (a material to be defibrated) 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 a bleeding inhibitor adhering to the raw material from the fibers.

  What has passed through the defibrating unit 20 is referred to as “defibrated material”. In addition to the defibrated fibers, the defibrated material includes resin (resin for binding multiple fibers), ink, toner, etc. separated from the fibers when the fibers are unwound In some cases, it may contain additives such as colorants, anti-bleeding agents, and paper strength enhancers. The shape of the defibrated material that has been unraveled is a string shape or a ribbon shape. The unraveled defibrated material may exist in an unentangled state (independent state) with other untangled defibrated materials, or entangled with other untwisted defibrated materials. It may exist in a state (a state forming a so-called “dama”).

  The defibrating unit 20 performs defibration by a dry method. Here, performing a process such as defibration in the air (in the air), not in the liquid, is called dry. In the present embodiment, the defibrating unit 20 uses a defibrator such as an impeller mill. Specifically, the defibrating unit 20 includes a torler (not shown) that rotates at high speed, and a liner (not shown) that is positioned on the outer periphery of the roller. The coarsely crushed pieces crushed by the crushing unit 12 are sandwiched between the rotor and the liner of the defibrating unit 20 and defibrated. The defibrating unit 20 generates an air flow by the rotation of the rotor. With this airflow, the defibrating unit 20 can suck the crushed pieces, which are raw materials, from the tube 2 and convey the defibrated material to the discharge port 24. The defibrated material is sent out from the discharge port 24 to the tube 3 and transferred to the sorting unit 40 through the tube 3.

  Thus, the defibrated material generated in the defibrating unit 20 is conveyed from the defibrating unit 20 to the sorting unit 40 by the air flow generated by the defibrating unit 20. Further, in the present embodiment, the sheet manufacturing apparatus 100 includes a defibrating unit blower 26 that is an airflow generation 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 a blower that is attached to the tube 3 and sucks air from the defibrating unit 20 together with the defibrated material, and blows air to the sorting unit 40.

  The sorting unit 40 has an inlet 42 through which the defibrated material defibrated from the tube 3 by the defibrating unit 20 flows together with the airflow. The sorting unit 40 sorts the defibrated material to be introduced into the introduction port 42 according to the length of the fiber. Specifically, the sorting unit 40 uses a defibrated material having a size equal to or smaller than a predetermined size among the defibrated material defibrated by the defibrating unit 20 as a first selected material, and a defibrated material larger than the first selected material. Is selected as the second selection. The first selection includes fibers, particles, or the like, and the second selection includes, for example, large fibers, undefibrated pieces (crushed pieces that have not been sufficiently defibrated), defibrated fibers agglomerated, or Includes entangled lumps.

In this embodiment, the sorting unit 40 includes a drum unit 41 (sieving unit) and a housing unit 43 (covering 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. Based on the mesh, the drum unit 41 sorts a first selection smaller than the mesh opening (opening) and a second selection larger than the mesh opening. As the net of the drum portion 41, for example, a metal net, an expanded metal obtained by extending a cut metal plate, or a punching metal in which a hole is 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 drum portion 41 together with the air current, and the first selected material falls downward from the mesh of the drum portion 41 by the rotation of the drum portion 41. The second selection that cannot pass through the mesh of the drum portion 41 is caused to flow by the airflow flowing into the drum portion 41 from the introduction port 42, led to the discharge port 44, and sent out to the pipe 8.
The tube 8 connects the inside of the drum portion 41 and the tube 2. The second selection flowed through the pipe 8 flows through the pipe 2 together with the crushed pieces crushed by the crushing section 12 and is guided to the inlet 22 of the defibrating section 20. As a result, the second selected item is returned to the defibrating unit 20 and defibrated.

  In addition, the first selection material selected by the drum unit 41 is dispersed in the air through the mesh of the drum unit 41 and is applied to the mesh belt 46 of the first web forming unit 45 located below the drum unit 41. Descent towards.

  The first web forming unit 45 (separating unit) includes a mesh belt 46 (separating 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 drawing by the movement of the rollers 47. The surface of the mesh belt 46 is constituted by a net in which openings of a predetermined size are arranged. Among the first selections descending from the selection unit 40, fine particles having a size that passes through the meshes fall below the mesh belt 46, and fibers of a size that cannot pass through the meshes accumulate on the mesh belt 46, and mesh. It is conveyed along with the belt 46 in the direction of the arrow. Fine particles falling from the mesh belt 46 include those that are relatively small or low in density (resin particles, colorants, additives, etc.) among the defibrated material, and are not removed by the sheet manufacturing apparatus 100 for use in sheet manufacturing. It is a thing.

The mesh belt 46 moves at a constant speed V1 during a normal operation for manufacturing a sheet. Here, the normal operation is an operation excluding the execution of start control and stop control of the sheet manufacturing apparatus 100, which will be described later. More specifically, the sheet manufacturing apparatus 100 manufactures a sheet having a desired quality. While you are.
Accordingly, the defibrated material that has been defibrated by the defibrating unit 20 is sorted into the first sorted product and the second sorted product by the sorting unit 40, and the second sorted product is returned to the defibrating unit 20. Further, the removed material is removed from the first selected material by the first web forming unit 45. The remainder after removing the removed matter from the first selection is a material suitable for manufacturing the 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 part 48 is connected to the dust collecting part 27 via the pipe 23. The dust collecting unit 27 is a filter type or cyclone type dust collecting device, and separates the fine particles from the air flow. 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 out of the sheet manufacturing apparatus 100 through a pipe 29 discharged by the collection blower 28.

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

  Accordingly, the first web W1 is formed on the mesh belt 46 by depositing fibers obtained by removing the removed material from the first selected material. By the suction of the collection blower 28, the formation of the first web W1 on the mesh belt 46 is promoted, and the removed material is quickly removed.

  Humidified air is supplied to the space including the drum unit 41 by the humidifying unit 204. The humidified air is humidified in the sorting unit 40 by the humidified air. This weakens the adhesion of the first selected item to the mesh belt 46 due to the electrostatic force, and facilitates the separation of the first selected item from the mesh belt 46. Furthermore, it can suppress that the 1st selection thing adheres to the inner wall of the rotary body 49 and the housing part 43 with an electrostatic force. In addition, the removal object can be efficiently sucked by the suction portion 48.

  In the sheet manufacturing apparatus 100, the configuration for sorting and separating the first defibrated material and the second defibrated material is not limited to the sorting unit 40 including the drum unit 41. For example, you may employ | adopt the structure which classifies the defibrated material processed by the defibrating unit 20 with a classifier. As the classifier, for example, a cyclone classifier, an elbow jet classifier, or an eddy classifier can be used. If these classifiers are used, it is possible to sort and separate the first sort and the second sort. Furthermore, the above classifier can realize a configuration in which removed objects including relatively small ones or low density ones (resin particles, colorants, additives, etc.) among the defibrated materials are separated and removed. For example, it is good also as a structure which removes the microparticles | fine-particles contained in a 1st selection material from a 1st selection material by a classifier. In this case, for example, the second sorted product may be returned to the defibrating unit 20, the removed product is collected by the dust collecting unit 27, and the first sorted product excluding the removed product may be sent to the pipe 54. .

  In the transport path of the mesh belt 46, air containing mist is supplied by the humidifying unit 210 to the downstream side of the sorting unit 40. The mist that is fine particles of water generated by the humidifying unit 210 descends toward the first web W1 and supplies moisture to the first web W1. Thereby, the amount of moisture contained in the first web W1 is adjusted, and 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 W <b> 1 accumulated on the mesh belt 46. The first web W <b> 1 is peeled off from the mesh belt 46 at a position where the mesh belt 46 is turned 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 accumulated to form a web shape, and the rotating body 49 loosens the fibers of the first web W1 and processes it into a state in which the resin can be easily mixed by the mixing unit 50 described later. .

Although the structure of the rotating body 49 is arbitrary, in this embodiment, it can be made into the rotating feather shape which has a plate-shaped blade | wing and rotates. The rotating body 49 is disposed at a position where the first web W1 peeled off from the mesh belt 46 and the blades are in contact with each other. Due to the rotation of the rotating body 49 (for example, the rotation in the direction indicated by the arrow R in the figure), the blade collides with the first web W1 which is peeled from the mesh belt 46 and conveyed, 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 tip of the blade 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 causes the mesh belt 46 to be damaged without being damaged. One web W1 can be divided efficiently.

The subdivided body P divided by the rotating body 49 descends inside the tube 7 and is transferred (conveyed) to the mixing unit 50 by the airflow flowing inside the tube 7.
Further, humidified air is supplied to the space including the rotating body 49 by the humidifying unit 206. Thereby, the phenomenon that fibers are adsorbed by static electricity to the inside of the tube 7 and the blades of the rotating body 49 can be suppressed. In addition, since high-humidity air is supplied to the mixing unit 50 through the pipe 7, the influence of static electricity can also be suppressed in the mixing unit 50.

The mixing unit 50 includes an additive supply unit 52 that supplies an additive containing a resin, a tube 54 that communicates with the tube 7 and through which an airflow including the subdivided body P flows, and a mixing blower 56.
The subdivided body P is a fiber obtained by removing the removed matter from the first sorted product that has passed through the sorting unit 40 as described above. The mixing unit 50 mixes an additive containing a resin with the fibers constituting the subdivided body P.

  In the mixing unit 50, an air flow is generated by the mixing blower 56, and is conveyed while mixing the subdivided body P and the additive in the pipe 54. Moreover, the subdivided body P is loosened in the process of flowing through the inside of the tube 7 and the tube 54, and becomes a finer fiber.

  The additive supply unit 52 (resin storage unit) is connected to an additive cartridge (not shown) that accumulates the additive, and supplies the additive inside the additive cartridge to the tube 54. The additive cartridge may be configured to be detachable from the additive supply unit 52. Moreover, you may provide the structure which replenishes an additive to an additive cartridge. The additive supply unit 52 temporarily stores an additive consisting of fine powder or fine particles inside the additive cartridge. The additive supply unit 52 includes a discharge unit 52a (resin supply unit) that sends the additive once stored to the pipe 54.

  The discharge unit 52 a 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 a pipeline that connects the feeder and the pipe 54. . When this shutter is closed, the pipe line or opening connecting the discharge part 52a and the pipe 54 is closed, and supply of the additive from the additive supply part 52 to the pipe 54 is cut off.

  In the state where the feeder of the discharge unit 52a is not operating, the additive is not supplied from the discharge unit 52a to the tube 54. However, when a negative pressure is generated in the tube 54, the feeder of the discharge unit 52a is stopped. Even so, the additive may flow to the tube 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 includes a resin 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 combination as appropriate. That is, the additive may contain a single substance, may be a mixture, or may contain a plurality of types of particles each composed of a single substance or a plurality of substances. The additive may be in the form of a fiber or powder.
The resin contained in the additive is melted by heating to bind the plurality of fibers to each other. Accordingly, 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.

  In addition to the resin that binds the fibers, the additive supplied by the additive supply unit 52 includes a colorant for coloring the fibers, a fiber agglomeration, and a resin depending on the type of the sheet S to be manufactured. It contains an aggregation inhibitor for suppressing aggregation and a flame retardant for making fibers difficult to burn. Moreover, the additive which does not contain a colorant may be colorless or light enough to be considered colorless, or may be white.

  Due to the air flow generated by the mixing blower 56, the subdivided body P descending the tube 7 and the additive supplied by the additive supply unit 52 are sucked into the tube 54 and pass through the mixing blower 56. The fibers constituting the subdivided body P and the additive are mixed by the air flow generated by the mixing blower 56 and / or the action of the rotating part such as the blades of the mixing blower 56, and this mixture (the first sort and the additive) ) Is transferred to the deposition section 60 through the tube 54.

  In addition, the mechanism which mixes a 1st selection material and an additive is not specifically limited, It may stir with the blade | wing which rotates at high speed, and uses rotation of a container like a V-type mixer. These mechanisms may be installed before or after the mixing blower 56.

  The depositing unit 60 deposits the defibrated material defibrated by the defibrating unit 20. More specifically, the depositing 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 lowers it while dispersing it 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 accumulation unit 60 includes a drum unit 61 (drum) and a housing unit 63 (covering unit) that accommodates the drum unit 61. The drum unit 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 the mesh, the drum portion 61 allows fibers and particles having a smaller mesh opening (opening) to pass through and lowers the drum portion 61 from the drum portion 61. The configuration of the drum unit 61 is the same as the configuration of the drum unit 41, for example.

  In addition, the “sieving” of the drum unit 61 may not have a function of selecting a specific object. That is, the “sieving” used as the drum part 61 means a thing provided with a net, and the drum part 61 may drop all of the mixture introduced into the drum part 61.

  A second web forming unit 70 is disposed below the drum unit 61. The 2nd web formation part 70 accumulates the passing material which passed the accumulation part 60, and forms the 2nd web W2 (deposit). The 2nd web formation part 70 has the mesh belt 72 (belt), the roller 74, and the suction mechanism 76, for example.

  The mesh belt 72 is an endless belt, is suspended on a plurality of rollers 74, and is conveyed in the direction indicated by the arrow in the drawing 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 configured by a net having openings of a predetermined size. Among the fibers and particles descending from the drum unit 61, fine particles having a size that passes through the mesh drops to the lower side of the mesh belt 72, and fibers having a size that cannot pass through the mesh are deposited on the mesh belt 72. 72 is conveyed in the direction of the arrow. During the operation of manufacturing the sheet S, the mesh belt 72 moves at a constant speed V2.

The mesh of the mesh belt 72 is fine and can be sized so that most of the fibers and particles descending from the drum portion 61 are not allowed to pass through.
The suction mechanism 76 is provided below the mesh belt 72 (on the side opposite to the accumulation unit 60 side). The suction mechanism 76 includes a suction blower 77, and can generate an air flow (an air flow directed from the accumulation portion 60 toward the mesh belt 72) downward to the suction mechanism 76 by the suction force of the suction blower 77.

The mixture dispersed in the air by the deposition unit 60 is sucked onto the mesh belt 72 by the suction mechanism 76. Thereby, formation of the 2nd web W2 on the mesh belt 72 can be accelerated | stimulated, and the discharge speed from the deposition part 60 can be enlarged. Furthermore, the suction mechanism 76 can form a downflow in the dropping path of the mixture, and can prevent the defibrated material and additives from being entangled during the dropping.
The suction blower 77 (deposition suction unit) may discharge the air sucked from the suction mechanism 76 out 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 matter contained in the air sucked by the suction mechanism 76 may be collected.

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

  As described above, the second web W <b> 2 in a state of containing a large amount of air and softly bulging is formed by passing through the depositing unit 60 and the second web forming unit 70 (web forming step). The second web W2 deposited on the mesh belt 72 is conveyed to the sheet forming unit 80.

  In the conveyance path of the mesh belt 72, air containing mist is supplied by the humidifying unit 212 to the downstream side of the deposition unit 60. Thereby, the mist which the humidification part 212 produces | generates is supplied to the 2nd web W2, and the moisture content which the 2nd web W2 contains is adjusted. Thereby, adsorption | suction etc. of the fiber to the mesh belt 72 by static electricity can be suppressed.

  The sheet manufacturing apparatus 100 is provided with a conveyance unit 79 that conveys the second web W2 on the mesh belt 72 to the sheet forming unit 80. The conveyance unit 79 includes, 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. Thus, the second web W2 is separated from the mesh belt 72 and is adsorbed by 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 the same, for example. Thus, the conveyance unit 79 peels and conveys the second web W2 formed on the mesh belt 72 from the mesh belt 72.

  The sheet forming unit 80 forms the sheet S from the deposit accumulated in the accumulation unit 60. More specifically, the sheet forming unit 80 pressurizes and heats the second web W2 deposited 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, thereby binding the plurality of fibers in the mixture to each other via the additive (resin). .

The sheet forming unit 80 includes a pressurizing unit 82 that pressurizes the second web W2 and a heating unit 84 that heats the second web W2 pressurized by the pressurizing unit 82.
The pressurizing unit 82 includes a pair of calendar rollers 85 and presses the second web W2 with a predetermined nip pressure. The second web W2 is reduced in thickness by being pressurized, and the density of the second web W2 is increased. One of the pair of calendar rollers 85 is a driving roller driven by a pressurizing unit driving motor (not shown), and the other is a driven roller. The calendar roller 85 conveys the second web W <b> 2 having a high density by pressurization 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 hot air blower, an infrared heater, and a flash fixing device. 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 pressed by the calendar roller 85, and forms a sheet indicated by a symbol S in FIG.
As described above, the second web W <b> 2 formed by the stacking unit 60 is pressed and heated by the sheet forming unit 80 to become a sheet S.

One of the pair of heating rollers 86 is a driving roller driven by a heating unit driving 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 calendar rollers 85 provided in the pressurizing unit 82 and the number of heating rollers 86 provided 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 a direction parallel to the conveyance direction F, and a first cutting unit 92 that cuts the sheet S in a direction that intersects with the conveyance direction of the sheet S indicated by a 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 sheet S having a predetermined size. The cut single 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 storage unit 103.

In the above configuration, the crushing unit 12 first crushes the raw material, and the sheet S is produced from the crushed raw material. For example, the sheet S is produced using fibers as the raw material. Is also possible.
For example, the structure which can be thrown into the drum part 41 by using the fiber equivalent to the defibrated material which the defibrating part 20 defibrated may be sufficient. Moreover, what is necessary is just to set it as the structure which can be thrown into the pipe | tube 54 by using the fiber equivalent to the 1st selection thing isolate | separated from the defibrated material as a raw material. In this case, the sheet S can be manufactured by supplying fibers processed from waste paper or pulp to the sheet manufacturing apparatus 100.

FIG. 3 is a schematic diagram showing the configuration of the accommodating portion 103.
The storage unit 103 has a storage unit main body 103H in which the sheets S are loaded from above and stores the sheets S in a stacked manner, and separates the lowest sheet S ′ one by one and conveys it to the guide 103G. The guide 103 </ b> G forms a conveyance path between the storage unit 103 and the printing apparatus 105.
The housing part main body 103H includes a bottom plate part 103T (bottom wall part) on which the sheets S are stacked and placed, and a wall part 103K (side wall part) rising from the periphery of the bottom plate part 103T. The wall 103K is provided with a discharge port 103W through which the lowest sheet S is discharged toward the guide 103G. The accommodating portion 103 includes a roller 103R that comes into contact with the lowest sheet S ′ from below.

  Each of the rollers 103R of the first to third storage units 103A to 103C is rotationally driven by first to third storage unit drive motors 343A to 343C (FIG. 4), and feeds the lowest sheet S toward the guide 103G ( Discharge). The guide 103G is provided with a conveyance mechanism (not shown) for conveying the sheet S to the printing apparatus 105, and the sheet S is conveyed to the printing apparatus 105 by the conveyance mechanism. The roller 103R constitutes a supply unit together with the first storage unit drive motor 343A, the second storage unit drive motor 343B, and the third storage unit drive motor 343C. In addition, when the accommodating part 103 and the printing apparatus 105 adjoin, you may convey to the printing apparatus 105 only with the roller 103R. Further, the storage unit 103 may include a belt instead of the roller 103R, and the belt S may be configured to feed out the lowest sheet S.

  The accommodating portion 103 includes a pressing member 103P that comes into contact with the uppermost sheet S in the accommodating 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 main body 103H toward the roller 103R. Accordingly, the lowest sheet S is held in contact with the roller 103R, and the sheet S can be appropriately fed out by the roller 103R.

  According to the storage unit 103, the sheets S can be discharged in the order of manufacture. That is, the storage unit 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 storage unit 103 and discharge the sheet S from the storage unit 103. Therefore, the waiting time on the printing apparatus 105 side until the sheet S is supplied to the printing apparatus 105 can be reduced.

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 a 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 programs executed by the main processor 111 and data to be processed.

  The nonvolatile storage unit 120 stores a program executed by the main processor 111 and data processed by the main processor 111. The nonvolatile 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 processing in which the main processor 111 detects an abnormality based on detection values of the various sensors.

The setting data 121 includes a 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, and manufacturing amount. (Manufactured number) and the like, and information for identifying the sorting conditions of the sorting unit 95 are included.
As the sorting condition, sorting based on the type of 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 basis weight of the value A is stored in the first storage unit 103A, and the sheet S having a basis weight of the value B is stored in the first sheet S. The sheet S having a basis weight of value C is accommodated in the first accommodating portion 103A and accommodated in the third accommodating portion 103C.

Here, there may be a case where a book that is bound using a sheet S having a different basis weight or color between the cover and the contents is desired to be printed by the printing apparatus 105. In such a case, it is conceivable to set the sorting based on the printing order of the sheets S. For example, the sheets S are manufactured in the page order (printing order) of a certain bookbinding and stored in the specific storage unit 103 in the manufacturing order (= page order). Then, by sequentially supplying the sheets S stored in the specific storage unit 103 to the printing apparatus 105 in the order of manufacture, printing can be performed in the page order of bookbinding. The distribution conditions are not limited to the above, and may be set as appropriate.
The setting data 121 also includes information on the set remaining amount that defines the minimum remaining amount of each storage unit 103. The value of the set remaining amount is information set by an operator who operates the sheet manufacturing apparatus 100, for example. The value of the set remaining amount is information used in “automatic sheet replenishment control” shown in FIG.

  The display data 122 is screen data that the main processor 111 displays on the display panel 116 (FIG. 4). The display data 122 is data for displaying, for example, the operation state of the sheet manufacturing apparatus 100, various set values, warning display, and the like. The display data 122 may be fixed image data, or 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 press operation. The touch sensor 117 is configured by, for example, a pressure sensing type or electrostatic capacitance type sensor having a transparent electrode, and is disposed on the display surface of the display panel 116. When the touch sensor 117 detects an operation, the touch sensor 117 outputs operation data including the 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 an 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 from 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 from the sensor into digital data. 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 acquired value to the main processor 111.

The sensor I / F 114 is connected to a used paper remaining amount sensor 301, a first accommodating portion remaining amount sensor 303A, a second accommodating portion remaining amount sensor 303B, and a third accommodating 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 storage unit remaining amount sensor 303A detects the amount of the sheet S stored in the first storage unit 103A. The second storage unit remaining amount sensor 303B detects the amount of the sheet S stored in the second storage unit 103B. The third storage unit remaining amount sensor 303C detects the amount of the sheet S stored in the third storage unit 103C. Hereinafter, the first to third storage unit remaining amount sensors 303 </ b> A to 303 </ b> C are referred to as a storage unit remaining amount sensor 303 when there is no need to particularly distinguish them.

  The control device 110 performs notification when the amount (remaining amount) of the sheets S detected by the respective accommodation unit remaining amount sensors 303 reaches a predetermined amount. In addition, the control device 110 automatically manufactures and replenishes the storage unit 103 for the types of sheets S stored in the storage unit 103 that are less than the set remaining amount (see “ Automatic sheet replenishment control ") is executed.

  The above configuration is an example. For example, the sheet manufacturing apparatus 100 may have other sensors, and the control device 110 may be able to acquire detection values of these sensors. For example, the sheet manufacturing apparatus 100 includes a sensor that detects the remaining amount of 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 humidification water, and the like. May be. In addition, the sheet manufacturing apparatus 100 may include a sensor that detects the temperature, the air volume, and the 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 part with which the sheet manufacturing apparatus 100 is provided is a motor, a pump, a heater, etc.
The drive unit I / F 115 includes, as control targets of the control device 110, a supply unit 10, a crushing unit 12, a defibrating unit 20, an additive supply unit 52, a blower 315, a humidification unit 316, a drum drive unit 317, and a belt drive. 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) provided 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 feeds 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 unit 316 includes humidifying units 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 driving unit 318 includes driving units 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. In addition, a heater, a vaporizing humidifier, a mist humidifier, or the like that heats the heating roller 86 may be connected to the driving 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 driving unit I / F 115 is connected to the pressurizing unit 82, the heating unit 84, the sorting unit 95, the first storage unit drive motor 343A, the second storage unit drive motor 343B, and the third storage unit drive motor 343C. The The first storage unit drive motor 343A drives the roller 103R of the first storage unit 103A. The second storage unit drive motor 343B drives the roller 103R of the second storage unit 103B. The third storage unit drive motor 343C drives the roller 103R of the third storage unit 103C. The control device 110 controls the start, stop, and rotation speed of the rotations of the first to third housing portion drive motors 343A to 343C. Hereinafter, the first to third housing portion drive motors 343A to 343C will be referred to as housing portion drive motors 343 when there is no need to distinguish between them.

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 sheet manufacturing apparatus 100 is turned on and the startup sequence is executed. As shown in FIG. 5, when a manufacturing instruction is input or when a preset manufacturing start date and time is reached (step S1A; YES), the control device 110 starts manufacturing the sheet S (step S2A). .

The control device 110 can receive a manufacturing start instruction, set a manufacturing start date and time, a manufacturing condition, and the like via an operation panel such as the touch sensor 117. The manufacturing conditions are the density (basis weight), shape (size, thickness), color, manufacturing amount (number of manufactured sheets), and the like of the sheet S.
Further, when the manufacturing instruction is not input or when the manufacturing start date / time is not reached (step S1A; NO), the control device 110 temporarily ends the process shown in FIG. 5 and executes the process of step S1A with a time interval. To do. Or you may comprise so that the process after step S2A may be performed by using the input of a manufacturing instruction as a trigger.

  In step S <b> 2 </ b> A, the control device 110 manufactures the sheet S by operating each part of the sheet manufacturing unit 101. In this case, for example, the control device 110 adjusts at least one of the adjustment of the speed V2 of the mesh belt 72 of the second web forming unit 70, the adjustment of the speed V1 of the mesh belt 46, and the adjustment of the amount of fibers lowered from the drum unit 61. By controlling this, the density of the sheet S is controlled. Moreover, the control apparatus 110 controls the color of the sheet | seat S by controlling the kind and quantity of the coloring agent which the additive supply part 52 adds. In addition, 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 pressurizing unit 82. As a result, the sheet S is manufactured in accordance with preset manufacturing conditions.

  The manufactured sheet S is discharged to the sorting unit 95. The control device 110 distributes the sheet S discharged to the distribution unit 95 to each storage unit 103 in accordance with a preset distribution condition (step S3A). Thereby, the sheet S is accommodated in each accommodating unit 103 for each type or for each printing order. In addition, the control device 110 includes a counting sensor (not shown) that counts the sheets S, or a configuration that counts the number of cuttings of the cutting unit 90 and the like, and can specify the production amount (manufactured number) of the sheets S.

  Subsequently, the control device 110 determines whether or not to complete the production of the sheet S (step S4A), and when the production is finished, stops the operation of each unit of the sheet production unit 101 (step S5A). The case where the production is finished is a case where the production amount of the sheet S reaches an amount according to the production conditions, a case where production stop is instructed via the touch sensor 117, or a case where the production stop date / time is reached. . As described above, the sheet S is manufactured so as to meet the manufacturing conditions, and the manufactured sheet S is distributed and stored in the storage units 103 according to the distribution conditions. The above is the basic operation of the sheet manufacturing apparatus 100.

The control device 110 can execute “automatic sheet replenishment control” for controlling 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 automatic sheet replenishment control.
The control device 110 can start the operation shown in FIG. 6 after the sheet manufacturing apparatus 100 is turned on and the startup sequence is executed. As shown in FIG. 6, the control device 110 determines whether or not the remaining amount of each storage unit 103 is less than a preset remaining amount based on the remaining amount detected by each storage unit remaining amount sensor 303. (Step S1B). Note that the set remaining amount may be the same value or a different value in the first to third accommodation units 103A to 103C.

When any remaining amount in the storage unit 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 storage unit 103 that does not satisfy the set remaining amount, and the sheet The production amount of S is specified (step S2B).
The specification of the type of the sheet S in this case is to specify information excluding the production amount other than the production amount among the production conditions of the sheet S. For example, referring to the sorting condition of the sheet S, etc. It is to specify the density, shape and color. The specification of the production amount of the sheet S is to specify a value that makes the remaining amount of the storage unit 103 a remaining amount exceeding the set remaining amount. For example, the remaining amount detected by the storage unit remaining amount sensor 303 Is set to a value (the number of sheets) that satisfies the set remaining amount. In this way, the manufacturing conditions for the sheet S to be manufactured are set.
When there are a plurality of storage units 103 that do not satisfy the set remaining amount, the manufacturing conditions for the sheet S are set for each storage 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 storage units 103 that do not satisfy the set remaining amount, the manufacture of the sheet S corresponding to one of the storage units 103 is started, and after the manufacture is completed, the sheet corresponding to another storage unit 103 is started. Started manufacturing S. For example, the manufacture of the sheet S of the type corresponding to the storage unit 103 having a large shortage with respect to the set remaining amount is started. Alternatively, the production of a sheet S of a type corresponding to a preset priority is started. Accordingly, a plurality of types of sheets S are manufactured together for each of the same type of sheets, and a situation in which the manufacturing conditions frequently change during manufacturing can be suppressed.
On the other hand, if it is determined in step S1B that all the accommodating units 103 satisfy the set remaining amount (step S1B; NO), the control device 110 ends the process shown in FIG. 6 and sets the time interval in step S1B. Execute the process.

  In step S3B, the control device 110 manufactures the sheet S in accordance with the manufacturing conditions by controlling each part of the sheet manufacturing unit 101 as in step S2A. Further, the control device 110 distributes and stores the manufactured sheet S in the corresponding storage unit 103 according to the distribution condition (step S4B).

  Subsequently, the control device 110 determines whether or not the production of the sheet S is finished (step S5B), and when the production is finished, the operation of each part of the sheet production unit 101 is stopped (step S6B). When the production is finished, the production amount of the sheet S reaches the target amount. As described above, when the remaining amount of any of the storage units 103 is less than the set remaining amount, the sheet S stored in the storage unit 103 is automatically manufactured and stored in the storage unit 103.

Note that the set remaining amount may be a common value for each storage unit 103 or may be a different value. For example, when a sheet S that 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 accommodation capacity of each accommodation unit 103 is the same, the remaining amount of the sheet S accommodated in the first accommodation unit 103A is initially set as the remaining amount when the paper is used evenly from the full state. Thus, the sheet 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 apparatus 105.
The control unit 105A of the printing apparatus 105 can start the operation illustrated in FIG. 7 after the printing apparatus 105 is turned on and the startup sequence is executed.
When the print data is input (received) (step S1C), the control unit 105A determines whether the sheet to be printed is supplied to the sheet manufacturing apparatus 100 (the storage unit 103) or the fourth storage unit 104 (step S1C). S2C). The sheet supply destination refers to a destination to which a sheet used by the printing apparatus 105 is supplied by manufacturing or manual feeding by the sheet manufacturing apparatus 100, and in another expression, a sheet supply source to the printing apparatus 105.
Here, whether or not the supply destination of the sheet to be printed is the storage unit 103 or the fourth storage unit 104 is determined by including information indicating the supply destination of the sheet 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 determines based on sheet information (for example, size) to be printed included in the print data may be applied. Note that the print data includes general print data contents, that is, information such as print contents, the type (for example, size) of the sheet S to be printed, and the print amount (number of printed sheets).

  When the sheet supply destination is the sheet manufacturing apparatus 100 (accommodating unit 103) (step S2C; YES), the control unit 105A can specify the sheet S to be printed and the print amount (number of prints) included in the print data. Information is transmitted to the sheet manufacturing apparatus 100 as print target information (step S3C). For example, the control unit 105A transmits print target information including information specifying the type of the sheet S to be printed and information indicating the print amount. Further, for example, the control unit 105 </ b> A sets information specifying the storage unit that stores the sheet S to be printed and the print amount among the first storage unit 103 </ b> A, the second storage unit 103 </ b> B, and the third storage unit 103 </ b> C. The print target information including the information to be displayed may be transmitted. Thereafter, 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 standby time exceeds a preset allowable time. For example, when the sheet manufacturing apparatus 100 cannot manufacture the sheet S to be printed due to a shortage of remaining used paper, 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.

  In the determination in step S2C, when the control unit 105A determines that the sheet supply destination is the fourth storage unit 104 (step S2C; NO), the control unit 105A requests the fourth storage unit 104 for a sheet to be printed (step S10C). The process proceeds to step S4C. For this reason, when a sheet is supplied from the fourth storage unit 104 (step S4C; YES), the control unit 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 printing, the control unit 105A determines whether or not to end printing (step S6C). When printing is to be ended, the operation of each unit of the printing apparatus 105 is stopped (step S7C). The case of ending printing is, for example, a case where printing based on print data has been completed. 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 storage unit 104 may be a paper feeder built in the printing apparatus 105 or a paper feeder externally connected to the printing apparatus 105.
In step S1C, when no print data is input (step S1C; NO), control device 110 ends the process shown in FIG. 7 and executes the process of step S1C with a time interval. Or you may comprise so that the process after step S2C may be performed by input of print data as a trigger.

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 print target information is input (received) (step S1D; YES), the control device 110 determines the sheet S based on the print target sheet S and the print amount specified by the print target information. It is determined whether or not manufacturing is necessary (step S2D).

Whether or not the sheet S needs to be manufactured is determined based on the remaining amount of the storage unit 103.
Specifically, the control device 110 determines that the manufacture of the sheet S is unnecessary when the sheet S to be printed is stored in any of the storage units 103 for a printing amount or more (step S2D; NO).
In this case, the control device 110 starts control to feed the printing target sheet S stored in the storage unit 103 to the printing device 105 (step S3D). Next, the control device 110 determines whether or not to end paper feeding (step S4D). When the sheet S to be printed is supplied to the printing apparatus 105 by the printing amount, the control unit 105A determines that the paper feeding is finished (step S4D; YES), and stops the paper feeding (step S5D).

  In step S <b> 2 </ b> D, the control device 110 needs to manufacture the sheet S when the remaining amount of the storage unit 103 that stores the sheet S to be printed is small (when the print amount is not satisfied) among the storage units 103. (Step S2D; YES). Further, the control device 110 determines that the sheet S needs to be manufactured even when the sheet S to be printed is not stored in all the storage units 103 (step S2D; YES).

However, even when the sheets S to be printed are not stored in all the storage units 103, if another sheet S is stored in all the storage units 103, even if the sheets S to be printed are manufactured, It is difficult to supply the sheet S from the storage units 103 to the printing apparatus 105 immediately. For this reason, the control device 110 is satisfied when the two conditions that the sheet S to be printed is not stored in any of the storage units 103 and one of the storage units 103 is empty are satisfied. However, it is preferable to determine that manufacture of the sheet S is necessary.
Note that, when the condition that any of the storage units 103 is empty is not satisfied, it is preferable that the control device 110 performs a notification process that prompts the user to empty any of the storage units 103. Then, when any of the storage units 103 becomes empty, the control device 110 may shift to the process of step S6D described later.

When it is determined that the sheet S needs to be manufactured (step S2D; YES), the control device 110 proceeds to the process of step S6D, specifies the insufficient sheet S as a manufacturing target sheet, and secures the insufficient number of sheets. Specify production volume. The target production amount may be the same as the shortage number or may be set to a larger number than the shortage number.
Next, the control device 110 starts manufacturing the sheet S to be manufactured (step S7D), and distributes the manufactured sheet S to the storage unit 103 according to the distribution condition (step S8D). Thus, the manufactured sheet S is accommodated in the accommodating portion 103 that should accommodate the sheet S to be printed.

  Further, the control device 110 starts control to feed the sheet S to be printed to the printing device 105 via the storage unit 103 (step S9D). In this configuration, as shown in FIG. 3, the storage unit 103 discharges the sheet S by FIFO, so that the supply and discharge of the sheet S to the storage unit 103 can be performed at the same time, and the manufactured sheet S can be quickly Can be supplied to the printing apparatus 105. Accordingly, it is possible to reduce the waiting time for printing, and complicated control for controlling the supply and discharge of the sheet S at different timings is unnecessary.

Subsequently, the control device 110 determines whether or not the production of the sheet 2 is finished (step S10D), and when the production is finished, stops the operation of each part of the sheet production unit 101 (step S11D). The case where the production is finished is a 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). When the feeding is finished, the operation of the storage unit 103 is stopped and the feeding is stopped (step S13D). ). The case where the paper feeding is ended 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 can be manufactured and fed to the printing apparatus 105.

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

  According to this configuration, the manufactured sheet S can be distributed and stored in the plurality of storage units 103 according to various standards such as type or printing order, and can be stored according to the side on which the manufactured sheet S is used. is there. Thereby, 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.

The sheet manufacturing apparatus 100 is preferably installed in an office or the like where waste paper suitable for the raw material of the sheet S is generated and the sheet S is used. This enables recyclable printing and paper recycling in the office.
In addition, since various sheets S are stored in the storage units 103, the manufacturing time of the sheets S is not easily restricted by the use time (the time zone for printing) of the sheets S. For example, when the sheet manufacturing apparatus 100 is installed in an office, the sheets S are manufactured in a time zone where there are few people, and sufficient sheets S are provided in a time zone where there are many people (a time zone where there is a lot of printing). It can be supplied to the printing apparatus 105. It is also possible to manufacture the sheet S and store it in each storage unit 103 at a time when the electricity rate is low.

  Further, since each storage 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. In addition, since the sheet S can be supplied to and discharged from the storage unit 103 at the same time, complicated control is not required and the printing waiting time can be reduced.

Further, the sheet manufacturing unit 101 can manufacture sheets S that are different in at least one of density (basis weight), size, and color. Thereby, it becomes easy to respond to the request of the side using the sheet S.
Moreover, the raw material of the sheet | seat S does not need to be specifically limited in the range which can be manufactured. Furthermore, 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 of different raw materials. As a result, the sheet 2 can be manufactured using a raw material (raw material) that meets the demands of the side using the sheet S.

  Further, the sheet manufacturing unit 101 includes a defibrating unit 20 that defibrates the coarsely crushed raw material in the air, and a web forming unit that deposits the defibrated material that has been defibrated by the defibrating unit 20 to form a web. 45 and 70, and the sheet formation part 80 which forms the sheet | seat S from a web. Thereby, compared with the case where the sheet manufacturing unit 101 is configured as a dry type and is configured as a so-called wet type, water-related facilities can be unnecessary or simplified, which 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 unit, processing unit) that performs printing on the sheet S fed out from each storage unit 103 of the sheet manufacturing apparatus 100. As a result, as described above, the sheet waiting time for printing is reduced, the situation in which the sheet S having an old manufacturing history remains, and the sheet manufacturing system 1 that can easily respond to the request from the side using the sheet S is provided. it can.

  Further, the printing apparatus 105 of the sheet manufacturing system 1 may be appropriately changed within a range where the number of the printing apparatuses 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 units 103 can be printed by a small number of printing apparatuses 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 limited, the number of printing apparatuses 105 may be the same as or more than the number of storage units 103.

  In the present embodiment, the case where the manufactured sheet S is used for printing is exemplified, but it may be used for other than printing. When used for purposes other than printing, another device that uses the sheet S may be provided instead of 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. For example, in step S3C shown in FIG. 7, information (usage target information) for specifying the sheet S to be used and the usage amount (number of used sheets) is transmitted to the sheet manufacturing apparatus 100, and instead of printing in steps S5C to S7C. You can start and stop using it.

  Further, as shown in FIG. 6, the sheet manufacturing apparatus 100 according to the present embodiment determines the type of the sheet S that the sheet manufacturing unit 101 manufactures based on the remaining amount of the sheet S stored in the plurality of storage units 103. A control device 110 for controlling is provided. According to this configuration, various sheets S can be stored in the plurality of storage units 103 with a sufficient remaining amount. Therefore, it is possible to quickly respond to the use (printing) of various sheets S, and to automatically replenish the sheets S to be used preferentially. Thereby, the restrictions regarding the use of the manufactured sheet S can be reduced, and in particular, the waiting time until use can be reduced.

In addition, as shown in FIG. 8, the control device 110 determines the type of the sheet S that the sheet manufacturing unit 101 manufactures based on the print target information (use target information) that is information that can specify the printing of the sheet S. Control. Thereby, the sheet S to be printed can be easily specified, and the sheet S consumed by printing can be automatically replenished with priority.
In addition, the control device 110 specifies a printing amount based on the print target information, and controls the manufacturing amount of the sheet manufacturing unit 101 based on the printing amount. Thereby, the sheet S can be manufactured in an amount corresponding to the printing amount, and an appropriate amount can be automatically replenished.

  Thus, for example, when printing a larger amount than the number of sheets stored in the storage unit 103, the manufacture of the sheet S can be started at an early stage, and the shortage of the sheets S used for printing can be easily resolved. As a result, the waiting time until printing can be efficiently reduced. 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 able to accept an interrupt from a user device such as interrupt printing from the printing apparatus 105 or an interrupt from an operator who operates the sheet manufacturing apparatus 100 or the printing apparatus 105. Also good. When an 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, an operation in which step S1D of the flowchart shown in FIG. 8 is a process for determining whether or not an interrupt is accepted may be executed.

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

  Further, the control device 110 manufactures a sheet S that does not satisfy the set remaining amount in the sheet manufacturing unit 101 when the sheet S stored in any of the storage units 103 does not satisfy the set remaining amount (predetermined remaining amount). Let Thereby, the sheet S with a small remaining amount can be automatically replenished with priority.

(Second Embodiment)
Next, the second embodiment will be described. In the second embodiment described below, the configuration of each part of the sheet manufacturing system 1 is the same as that of the first sheet manufacturing system 1 embodiment. For this reason, about each structure which is common in 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 9 is an explanatory diagram of the operation of the sheet manufacturing system 1 in the second embodiment. Reference numerals P <b> 11, P <b> 12, and P <b> 13 in FIG. Reference numeral P <b> 21 indicates processing executed by the sheet manufacturing unit 101, the control device 110, and the printing device 105 (processing unit).

  In the sheet manufacturing system 1, the automatic replenishment control described with reference to FIG. 6 is performed on each of the first storage unit 103A, the second storage unit 103B, and the third storage unit 103C of the storage unit 102. For example, in the automatic replenishment control process P11 for the first storage unit 103A, the control device 110 performs a remaining amount detection P12A for detecting the remaining amount of the sheet S in the storage unit 103, and based on the result of the remaining amount detection P12A, the sheet S is manufactured and discharged into the first housing portion 103A. Similarly, the control device 110 executes the automatic replenishment control processes P12 and P13 for the second storage unit 103B and the third storage unit 103C, detects the remaining amount of the sheet S, and manufactures the sheet S. To do. Although not shown, automatic replenishment control is also performed on the fourth storage unit 104.

  In the sheet manufacturing system 1, the sheet S is supplied from the storage unit 103 of the storage unit 102 to the printing apparatus 105 by the printing process P <b> 21 and is printed on the sheet S by the printing apparatus 105. The printing process P21 can be executed for any of the first storage unit 103A, the second storage unit 103B, and the third storage unit 103C, and FIG. 9 shows an example in which the print processing P21 is performed on the first storage unit 103A.

  The sheet manufacturing system 1 can execute the automatic replenishment control processing P11, P12, and P13 at an arbitrary timing during the operation of the sheet manufacturing system 1. For example, when the control device 110 constantly executes a process for detecting the remaining amount of the sheet S (remaining amount detection P12A) and the remaining amount is less than a preset remaining amount (step S1B; YES), the sheet S is manufactured. can do.

  In the sheet manufacturing system 1, the printing process P <b> 21 can be executed at an arbitrary timing during the operation of the sheet manufacturing system 1. That is, when the printing apparatus 105 receives print data from an external apparatus (not shown) such as a personal computer (step S1C), the printing process P21 can be started based on the print data.

  In the sheet manufacturing system 1, the automatic replenishment control processing P11, P12, P13 and the printing processing P21 can be executed asynchronously without adjusting the execution timing of the mutual processing. That is, it is not necessary to synchronize the timing for executing the automatic replenishment control process P11, P12 or P13 and the timing for executing the printing process P21. Further, the process of printing on the sheet S of the second storage unit 103B and the process of printing on the sheet S of the third storage unit 103C can be executed asynchronously with the automatic replenishment control processes P11, P12, and P13.

  Furthermore, in the sheet manufacturing system 1, the printing process P21 executed asynchronously and the automatic replenishment control processes P11, P12, and P13 can be appropriately linked. Specifically, an interrupt process P31 can be generated for the automatic replenishment control processes P11, P12, and P13 in response to the printing apparatus 105 consuming the sheet S by the print process P21. The interruption process P31 is a process executed in association with the execution of the printing process P21. In response to the decrease of the sheet S by the printing process P21, the sheet S is quickly printed by the automatic replenishment control processes P11, P12, and P13. It is a process to make. In the interrupt processing P31, the control device 110 detects the remaining amount detection P12A for the automatic replenishment control processing P11, P12, and P13 when the remaining amount of the sheet S in the storage unit 103 is smaller than the printing amount printed by the printing device 105. Regardless of the result, an instruction is given to start production of the sheet S. Thereby, manufacture and replenishment of the sheet S can be started before the amount of the sheet S in the storage unit 103 is significantly reduced. The sheet S can be replenished more quickly than when the printing apparatus 105 executes the printing process P21 and the sheet S is manufactured after the remaining amount of the sheet S actually decreases.

FIG. 10 is a sequence diagram showing the operation of the sheet manufacturing system 1 in the second embodiment.
As described above, the sheet manufacturing unit 101 can execute the operation of supplying the sheet S to the storage unit 102 asynchronously with the operation of printing by the printing apparatus 105. Specifically, the sheet manufacturing unit 101 can execute the automatic replenishment control process in step ST1, can also perform the automatic replenishment control process in step ST2, and the same is true at other timings (eg, step ST4). The printing apparatus 105 can execute the printing process before, after or during the automatic replenishment control process. In this case, when the printing apparatus 105 transmits information to be printed and requests paper feeding (step ST3), the sheet manufacturing unit 101 supplies the sheet S from the storage unit 102 to the printing apparatus 105 in response to the request. (Step ST5).

FIG. 11 is a flowchart showing the operation of the printing apparatus 105 according to the second embodiment.
The operation shown in FIG. 11 is executed by the printing apparatus 105 instead of the operation shown in FIG. When the print data is input (received) (step S1E), the control unit 105A uses the information that can specify the print target sheet S and the print amount (number of prints) included in the print data as print target information to manufacture the sheet. It transmits to the apparatus 100 (step S2E). The operation in step S2E corresponds to the operation in step ST3 in FIG.

  Here, the control unit 105A determines whether or not information indicating the remaining amount of the type of sheet S included in the print target information has been notified from the sheet manufacturing apparatus 100 (step S3E). When the remaining amount is notified (step S3E; YES), the control unit 105A acquires the notified remaining amount (step S4E) and determines whether the sheet S is supplied (step S5E). When the remaining amount of the sheet S is not notified (step S3E; NO), the control unit 105A determines whether or not the sheet S is supplied (step S5E).

  While the sheet S is not supplied (step S5E; NO), the control unit 105A stands by. When the sheet S is supplied from the sheet manufacturing apparatus 100 (step S5E; YES), the control unit 105A controls the print head and the like to start printing on the supplied sheet S (step S6E). The subsequent operations (steps S7E to S8E) are the same as steps S6C to S7C in FIG.

  FIG. 12 is a flowchart showing the operation of the sheet manufacturing apparatus 100 according to the second embodiment, and shows the operation when the sheet manufacturing apparatus 100 acquires print target information (step S2E in FIG. 11) from the printing apparatus 105. The operation shown in FIG. 12 is executed by the sheet manufacturing apparatus 100 instead of the operation shown in FIG.

The control device 110 starts an automatic replenishment control process (corresponding to P11, P12, and P13 in FIG. 9) at the start of the operation in FIG. 12 (step S1F).
When the print target information is not input (received) (step S2F; NO), the control device 110 ends this process. Further, when the printing target information is input (received) (step S2F; YES), the control device 110 detects the remaining amount of the printing target sheet S specified by the printing target information (step S3F). This remaining amount is the remaining amount detected by the sensor in the storage unit 103 that stores the type of sheet S specified by the print target information. The control device 110 notifies the printing device 105 of the detected remaining amount of the sheet S (step S4F).

  The control device 110 compares the remaining amount of the sheet S detected in step S3F with the print amount specified by the print target information received in step S2F, and determines whether or not the remaining amount of the sheet S is less than the print amount. Is determined (step S5F).

When the remaining amount of the sheet S is less than the printing amount (step S5F; YES), the control device 110 performs automatic replenishment control processing for the sheet S used for printing, that is, the type of sheet S specified by the received print target information. Then, an interrupt is executed (step S6F). The content of the interruption is an instruction to manufacture the sheet S even if the remaining amount of the sheet S detected by the sensor is greater than or equal to the set remaining amount for the storage unit 103 that stores the type of sheet S specified by the print target information. Information. Here, the sensor refers to the remaining sheet S of the type specified by the print target information among the first storage unit remaining amount sensor 303A, the second storage unit remaining amount sensor 303B, and the third storage unit remaining amount sensor 303C. One or more sensors that detect the amount.
Thereafter, the control device 110 starts feeding the sheet S from the storage unit 102 to the printing device 105 (step S7F).
If the remaining amount of the sheet S is equal to or greater than the printing amount (step S5F; NO), the control device 110 starts feeding without interrupting the automatic replenishment control process (step S7F).

  The subsequent operations in steps S8F to S9F are the same as those in steps S4D to S5D (FIG. 8).

  In the operation described with reference to FIGS. 11 and 12, the process (steps S4F, S3E to S4E) in which the sheet manufacturing apparatus 100 notifies the printing apparatus 105 of the remaining amount of the sheet S may be omitted.

  A sheet manufacturing system 1 according to the second embodiment includes a sheet manufacturing apparatus 100 that manufactures a plurality of types of sheets S, and a storage unit 103 that stacks and stores the sheets S manufactured by the sheet manufacturing apparatus 100. In addition, the sheet manufacturing system 1 includes a supply unit that feeds out the lowest sheet S among the sheets S stored in the storage unit 103. Further, the sheet manufacturing system 1 includes a printing apparatus 105 that processes the sheet S fed from the storage unit 103 by the supply unit.

  As a result, the sheet S is manufactured by the sheet manufacturing apparatus 100 and stacked and stored, and the lowest sheet S among the stored sheets S can be fed to the printing apparatus 105 and used. According to this configuration, since the lowermost sheet S stored in the storage unit 103 is fed out, the supply (storage) and discharge of the sheet S to the storage unit 103 can be performed at the same time. It can be used in the order of manufacture in a first-in first-out (FIFO) mode. For this reason, the manufactured sheet S can be processed promptly, complicated control is unnecessary, and the waiting time on the use side can be reduced. Therefore, it is possible to reduce restrictions on the use of the manufactured sheet S with a configuration capable of manufacturing the sheet S.

  In addition, the sheet manufacturing apparatus 100 executes automatic replenishment control for manufacturing the sheet S corresponding to the remaining amount of the sheet S stored in the storage unit 103. The printing apparatus 105 requests the supply of the sheet S by the supply unit, and executes a printing process on the sheet S fed out by the supply unit in response to the request. Here, the execution timing of the automatic replenishment control and the printing process can be determined independently of each other. For this reason, the operation | movement which manufactures the sheet | seat S and replenishes the accommodating part 103, and the process using the sheet | seat S can be performed at an independent timing, and the restrictions regarding utilization of the manufactured sheet | seat S can be reduced further.

  In addition, the sheet manufacturing apparatus 100 executes automatic replenishment control for manufacturing the sheet S corresponding to the remaining amount of the sheet S stored in the storage unit 103. The printing apparatus 105 requests the supply of the sheet S by the supply unit, and print processing for the sheet S fed out by the supply unit in response to the request is at least one of before, after, and during execution of the automatic replenishment control. It can be executed at two or more timings. Accordingly, since the sheet S stored in the storage unit 103 can be used before, after, or during the operation of manufacturing the sheet S and replenishing the storage unit 103, there are restrictions on the use of the manufactured sheet S. It can be further reduced.

  Further, the sheet manufacturing apparatus 100 detects the remaining amount of the sheet S stored in the storage unit 103 in the automatic replenishment control, and manufactures the sheet S when the detected remaining amount of the sheet S is less than a set amount. . Further, when the printing apparatus 105 starts the printing process, the sheet S corresponds to the amount of the sheet S consumed in the process even if the remaining amount of the sheet S detected by the automatic replenishment control is equal to or larger than the set value. Manufacturing. As a result, in addition to the operation of manufacturing and replenishing the sheet S when the remaining amount of the sheet S is low, the sheet S is manufactured when the sheet S in the storage unit 103 is used. Thus, the sheet S can be quickly manufactured. Accordingly, the shortage of the sheet S can be prevented, and restrictions on the use of the manufactured sheet S can be further reduced.

  Further, the printing apparatus 105 outputs print target information including information indicating the type of the sheet S used for printing and information indicating the printing amount. The sheet manufacturing apparatus 100 manufactures the sheet S based on the printing amount specified by the print target information output from the printing apparatus 105 and the remaining amount of the sheet S in the storage unit 103. Accordingly, when printing is performed on the sheet S stored in the storage unit 103, the sheet S is manufactured based on the printing amount and the remaining amount of the sheet S in the storage unit 103. Can be prevented. Therefore, restrictions on the use of the manufactured sheet S can be further reduced.

(Third embodiment)
FIG. 13 is a view showing a sheet manufacturing system 1 according to the third embodiment. In the following description, the same parts as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and different parts are described.
The sheet manufacturing system 1 includes a takeout storage unit 103D that allows a user to freely take out a predetermined sheet S manufactured by the sheet manufacturing unit 101. The user can take out the sheet S from the take-out storage unit 103D and set it in an arbitrary printing apparatus or the like.
For example, when the sheet manufacturing system 1 is disposed in an office, the printing apparatus is also present at a position away from the sheet manufacturing system 1. By providing the take-out storage unit 103D, various users can use the recycled sheet S in a printing apparatus that exists at a distant position, and the use of the sheet S can be promoted.

  The take-out accommodating portion 103D of this configuration is not connected to the printing apparatus 105 in the sheet manufacturing system 1 and is configured as a take-out stacker. This take-out accommodating portion 103D may have the same configuration as the other accommodating portions 103A to 103C, or may have a different configuration. Further, the take-out accommodating unit 103 </ b> D may also be connected to the printing apparatus 105. In this configuration, a take-out storage unit remaining amount sensor 303D that detects the amount of the sheet S stored in the take-out storage unit 103D is provided. Based on the detection result of the sensor 303D, the control device 110 controls the take-out storage unit 103D. The remaining amount of the sheet can be detected.

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

Further, the control shown in FIG. 6 is not performed for the other storage units 103A to 103C, and an administrator who manages the sheet manufacturing system 1 manufactures the sheet S stored in the other storage units 103A to 103C as appropriate. Let
In this way, it is possible to efficiently avoid a situation in which the remaining amount of the specific storage unit (the extraction storage unit 103D) becomes empty. In addition, a specific accommodating part is not limited to the accommodating part 103D for extraction, Other accommodating parts 103A-103C may be sufficient, and the several accommodating part 103 may be made into a specific accommodating part.

(Fourth embodiment)
The fourth embodiment differs from the first embodiment in that the sheet manufacturing unit 101 is electrostatic.
FIG. 14 is a schematic diagram illustrating a main part of the sheet manufacturing unit 101 of the fourth embodiment.
The sheet manufacturing unit 101 performs post-processing for electrostatically transferring the fiber-containing material as a raw material to the transport belt 401 (transfer target) and adjusting 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 carries the supplied fiber-containing material, and a conveyor belt on which the supported fiber-containing material is electrostatically transferred. 401 and a post-processing unit 430 that 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). Thereby, it is possible to prevent variation 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 including cellulose fibers and a hydrophobic material covering at least a part of the cellulose fibers, and is heated by pressure by the post-processing unit 430, thereby receiving ink. A layer is formed.
Cellulose fibers may be derived from cellulose products such as waste paper, or may be derived from 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 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 repelling of the ink when the ink is applied to the sheet S, and has excellent ink absorption It becomes. In addition, the hydrophobic material coats the cellulose fibers and stabilizes the charging characteristics of the composite. Thereby, an ink receiving layer can be suitably 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 charging characteristics or a colorant for adjusting the color of the sheet S.

The storage part 412 stores the 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 the rotation of the roller 414. The first carrier 415 has a potential difference with the roller 414, and the fiber-containing material adheres electrostatically. The blade 416 adjusts the thickness (attachment amount) of the fiber-containing material adhering to the first carrier 415 to adjust the sheet shape to a predetermined thickness (thin film), 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 adheres electrostatically. The carrier 420 is a rotating roller member, and transfers the fiber-containing material carried on the carrier 420 to the conveyance 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, a transfer unit 424 that transfers the fiber-containing material to the transport belt 401 by an electrostatic force generated by a potential difference with the support body 420 is provided around the support body 420.

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

  The post-processing unit 430 includes a leveling processing unit 431 that smoothes the surface of the fiber-containing material transferred to the conveyor belt 401, a pressure processing unit 432 that pressurizes the fiber-containing material, and a semi-solidifying surface of the fiber-containing material. A solidification processing unit 433 and an ink receiving layer solidifying unit 434 that solidifies an ink receiving layer composed of a layered fiber-containing material are provided. The leveling treatment unit 431 includes a leveling roller 435 having at least an outer peripheral surface of a metal surface, smoothes the surface of the fiber-containing material by the leveling roller 435, and applies to the fiber-containing material via the ground wire 436. Perform static elimination.

  The pressure processing unit 432 combines the fiber-containing materials by pressurization with the pressure roller 437 and uniformizes the density. The semi-solidification processing unit 433 includes 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 unit 434 includes a solidifying roller 440 and a heater 441 provided in the solidifying roller 440, heats the solidifying roller 440 by energizing the heater 441, and heats the ink receiving layer by the solidifying roller 440. However, the ink receiving layer is pressurized 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 solidification roller 440, for example, it is naturally cooled, bound, and solidified. In this manner, the fiber-containing material 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 that facilitate the separation of the sheet S from the conveyance belt 401 are provided downstream of the post-processing unit 430.
