The user takes out the paper supplied to the paper discharge unit 96 and uses it.

  The control device 110 is configured by a main processor, a memory, various interfaces and the like, details of which will be described later. The control device 110 controls the overall operation of the sheet processing apparatus 100 and the authentication unit 150 that performs user authentication processing by executing a control program for the sheet processing apparatus 100 stored in the memory on the main processor.

[2. Structure of mechanical part]
FIG. 2 is a schematic diagram illustrating a configuration of a mechanism unit of the sheet processing apparatus 100. Referring to FIG. 2, the sheet processing apparatus 100 improves the bond strength and whiteness of paper products, colors, fragrances and the like according to the use by mixing various additives with the fiberized raw material. In addition, functions such as flame retardancy may be added. In addition, by controlling the density, thickness, and shape of the paper, various thicknesses and sizes of paper such as A4 and A3 office paper and business card paper can be manufactured.

  The sheet processing apparatus 100 includes a supply unit 10a, 10b, 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 stacking unit 60, and a second web forming unit. 70, a conveyance unit 79, a sheet forming unit 80, a cutting unit 90, and a paper discharge unit 96. Here, the roughening unit 12, the defibrating unit 20, the sorting unit 40, and the like constitute the defibrating unit 200 shown in FIG. The reproduction unit 250 shown in FIG. 1 includes the first web forming unit 45, the rotating body 49, the mixing unit 50, the stacking unit 60, the second web forming unit 70, the conveying unit 79, the sheet forming unit 70, the cutting unit 90, and the like. Is configured. The defibrating unit 200 and the reproducing unit 250 constitute a sheet processing unit of the present invention.

  The sheet processing 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 examples thereof include a steam type, a vaporization type, a hot air vaporization type, and an ultrasonic type.

  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, and 208 have a filter (not shown) that infiltrates water, and supplies humidified air with increased humidity by allowing air to pass through the filter.

  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 units 10 a and 10 b supply raw materials to the crushing unit 12. The raw material which the sheet processing apparatus 100 manufactures a sheet should just contain a fiber, for example, paper, pulp, a pulp sheet, the cloth containing a nonwoven fabric, or a textile fabric etc. are mentioned. In this embodiment, a configuration in which the sheet processing apparatus 100 uses waste paper as a raw material is illustrated. In the present embodiment, the supply units 10 a and 10 b include a tray that accumulates and accumulates waste paper, and the waste paper is sent from the tray to the crushing unit 12.

  The crushing unit 12 cuts (crushes) the raw material supplied by the supply unit 10 with a crushing blade 14 into a crushing piece. The rough crushing blade 14 cuts the raw material in the air (in the air) or the like. The crushing unit 12 includes, for example, a pair of crushing blades 14 that are cut with a raw material interposed therebetween, and a drive unit that rotates the crushing blades 14, and can have a configuration similar to 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 cuts the raw material into pieces of paper having a size of 1 to several cm square or less.

  The crushing unit 12 includes a chute (hopper) 9 that receives the crushing pieces that are cut by the crushing blade 14 and fall. The chute 9 has, for example, a taper shape in which the width gradually decreases in the direction in which the coarsely crushed pieces flow (the traveling direction). Therefore, the chute 9 can receive many coarse fragments. 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) cut by the crushing blade 14 to the defibrating unit 20. . The coarsely crushed pieces are collected by the chute 9 and transferred (conveyed) through the tube 2 to the defibrating unit 20.

  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 that the crushed material cut | judged with the crushed blade 14 adsorb | sucks to the chute | shoot 9 or the inner surface of the pipe | tube 2 by static electricity can be suppressed. In addition, since the crushed material cut by the pulverizing blade 14 is transferred to the defibrating unit 20 together with humidified (high humidity) air, the effect of suppressing adhesion of the defibrated material inside the defibrating unit 20 is also achieved. I can expect. 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. Moreover, you may neutralize using an ionizer with the humidification part 202. FIG.

  The defibrating unit 20 defibrates the crushed material cut by the crushing unit 12. More specifically, the defibrating unit 20 defibrates the raw material (crushed pieces) cut by the crushing unit 12 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 that have been unraveled, the “defibrated material” includes resin particles (resins that bind multiple fibers together), ink, toner, etc. In some cases, additives such as colorants, anti-bleeding agents, paper strength enhancers and the like are included. 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 undisentangled fibers, or entangled with other undisentangled defibrated material to form a lump. 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 an impeller mill. Specifically, the defibrating unit 20 includes a rotor (not shown) that rotates at high speed, and a liner (not shown) that is positioned on the outer periphery of the rotor. The coarsely crushed pieces cut by the coarse pulverization unit 12 are sandwiched between the rotor of the defibrating unit 20 and the liner 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. Furthermore, in the present embodiment, the sheet processing 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 attached to the pipe 3, sucks air from the defibrating unit 20 together with the defibrated material, and blows it 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 or particles, and the second selection includes, for example, large fibers, undefibrated pieces (crushed pieces that have not been sufficiently defibrated), and defibrated fibers agglomerated or entangled. Including tama etc.

  In the present embodiment, the sorting unit 40 includes a drum unit (sieving unit) 41 and a housing unit (covering unit) 43 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 coarsely crushed pieces cut by the coarse crushing section 12 and is guided to the introduction port 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 (separation unit) includes a mesh belt 46 (separation belt), a roller 47, and a suction unit (suction mechanism) 48. 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 relatively small ones and low density ones (resin particles, colorants, additives, etc.) among the defibrated materials, and the sheet processing apparatus 100 does not use them for the production of the sheet S. It is a removed product.

  During the normal operation of manufacturing the sheet S, the mesh belt 46 moves at a constant speed V1. Here, the normal operation is an operation excluding the start control and stop control of the sheet processing apparatus 100 to be described later, and more specifically, the sheet processing apparatus 100 manufactures a sheet S having a desirable quality. It points to while doing.

  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 obtained by removing the removed material from the first selection is a material suitable for manufacturing the sheet S, 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 fine particles from the air current. A collection blower 28 (separation suction unit) is installed downstream of the dust collection unit 27, and the collection blower 28 sucks air from the dust collection unit 27. Further, the air discharged from the collection blower 28 is discharged out of the sheet processing apparatus 100 through the pipe 29.

  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. Thereby, the adhesion of the first selection to the mesh belt 46 due to the electrostatic force can be weakened, and the first selection can be easily separated from the mesh belt 46. Furthermore, it can suppress that the 1st selection object adheres to the inner wall of the rotary body 49 or 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 processing 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 products including relatively small ones having a low density (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 processing 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 W <b> 1 that is peeled from the mesh belt 46 and is transported, 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 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 (transfer blower).

  The subdivided body P is a fiber obtained by removing the removed material 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 composed 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, or polyethylene terephthalate. Alternatively, polyphenylene ether, polybutylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like. These resins may be used alone or in combination. 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 and binds a plurality of fibers. 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 fiber, the additive supplied by the additive supply unit 52 includes a colorant for coloring the fiber, fiber aggregation, and resin aggregation depending on the type of sheet to be manufactured. It may also contain a coagulation inhibitor for suppressing odor, and a flame retardant for making the 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 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 (covering unit) 63 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 (web formation part) 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. Further, the moving speed of the mesh belt 72 can be controlled by the control device 110 (FIG. 1). During the normal operation of manufacturing the sheet S, the mesh belt 72 moves at a constant speed V2. The normal operation is as described above.

  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 to the outside of the sheet processing 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 processing apparatus 100 is provided with a conveyance unit 79 that conveys the second web W <b> 2 on the mesh belt 72 to the sheet forming unit 80. The conveyance unit 79 includes, for example, a mesh belt 79a, a 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, and 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 by pressurizing and heating the second web W <b> 2 deposited on the mesh belt 72 and conveyed by the conveying unit 79. 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. The pressurizing unit 82 includes a pressurizing unit driving motor 332 (FIG. 4). One of the pair of calendar rollers 85 is a driving roller driven by the pressurizing unit driving motor 332, and the other is a driven roller. The calendar roller 85 is rotated by the driving force of the pressurizing unit driving motor 332 and conveys the second web W <b> 2 that has become dense due to 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 heats the second web W <b> 2 pressed by the calendar roller 85 to form the sheet S.

  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.

  The heating unit 84 includes a heating unit drive motor 331 (FIG. 4). One of the pair of heating rollers 86 is a driving roller driven by a heating unit driving motor 331, and the other is a driven roller. The heating roller 86 is rotated by the driving force of the heating unit driving motor 331 and 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.

  Thus, a single-sheet sheet S having a predetermined size is formed. The cut single sheet S is discharged to the paper discharge unit 96. The paper discharge unit 96 includes a tray or stacker on which sheets S of a predetermined size are placed.

  In the above configuration, the humidifying units 202, 204, 206, and 208 may be configured by a single vaporizing humidifier. In this case, the humidified air generated by one humidifier may be branched and supplied to the crushing unit 12, the housing unit 43, the pipe 7, and the housing unit 63. This configuration can be easily realized by branching and installing a duct (not shown) for supplying humidified air. Of course, the humidifying sections 202, 204, 206, and 208 can be configured by two or three vaporizing humidifiers.

  Moreover, in the said structure, the humidification parts 210 and 212 may be comprised with one ultrasonic humidifier, and may be comprised with two ultrasonic humidifiers. For example, the air containing the mist which one humidifier produces | generates can be set as the structure branched and supplied to the humidification part 210 and the humidification part 212.

[6. Operation of sheet processing apparatus]
FIG. 7 is a flowchart showing the operation of the sheet processing apparatus 100 (100a, 100b). Since the configuration and operation of the first sheet processing apparatus 100a and the second sheet processing apparatus 100b are the same, the operation of the first sheet processing apparatus 100a will be described below.

  Steps S <b> 1 to S <b> 3 and step S <b> 10 in FIG. 7 are processes performed by the authentication unit 150. When the authentication unit 150 accepts a user authentication operation by inserting an ID card into the card reader 130 in step S1, the authentication unit 150 proceeds to step S2. In step S2, authentication unit 150 determines whether there is an empty supply unit (whether at least one of supply units 10a and 10b is empty).

  And the authentication part 150 advances a process to step S3, when there exists an empty supply part. If there is no empty supply unit, the authentication unit 150 proceeds to step S10, displays a guide screen such as “Please wait until there is no paper currently being processed” on the display panel 116, and proceeds to step S1. Proceed with the process.

  In step S3, the authentication unit 150 transmits the user ID read from the ID card to the management server 500 to request user authentication. Here, the data of the user ID transmitted from the first sheet processing apparatus 100a to the management server 500 corresponds to determination request data for requesting determination as to whether or not the user of the present invention is a specific user.

  The management server 500 refers to the user DB 511 for the user ID received from the first sheet processing apparatus 100a, and determines whether or not the use of the first sheet processing apparatus 100a is permitted. The configuration for performing this determination corresponds to the determination unit of the present invention. If the use of the first sheet processing apparatus 100a is permitted, the management server 500 returns data indicating “authentication OK”, and if the use of the first sheet processing apparatus 100a is not permitted, the management server 500 returns “ Data indicating “authentication NG” is returned. Here, the data indicating “authentication OK” and the data indicating “authentication NG” correspond to the determination result data of the present invention.

  The authentication unit 150 determines whether the data indicating “authentication OK” or the data indicating “authentication NG” is received from the management server 500, and the user is permitted to use the first sheet processing apparatus. Authenticates whether the user is a specific user.

  Subsequent step S4 and subsequent steps are processing by the control unit 151. In step S4, the control unit 151 determines whether or not the waste paper is set in the supply unit 10a or the supply unit 10b and the cover 702a or the cover 702b is closed, in the paper detection units 705a and 705b and the open / close detection units 704a and 704b. Recognize based on the detection signal. Then, when the control unit 151 recognizes that the paper is set in the supply unit 10a or the supply unit 10b and the cover 702a or the cover 702b is closed, the process proceeds to step S5.

  In step S5, the control unit 151 determines whether or not the authentication by the authentication unit 150 is successful in step S3. When the authentication is successful (when the user is a specific user), the process proceeds to step S6. Then, in step S6, the control unit 151 sets the supply unit (the supply unit 10a or the supply unit 10b) on which the user has set the paper as a confidential supply unit (a supply unit that feeds paper while maintaining a confidential state). . In subsequent step S7, the control unit 151 executes a waste paper recycling process (a process according to a flowchart of FIG. 8 described later) for the confidential supply unit.

  On the other hand, when the authentication by the authentication unit 150 fails in step S3 (when the user is not a specific user), the control unit 151 advances the process from step S5 to step S20. Then, in step S20, the control unit 151 turns the supply unit (the supply unit 10a or the supply unit 10b) on which the user has set paper into a non-confidential supply unit (a supply unit that feeds paper while maintaining a non-confidential state). Set. In subsequent step S21, the control unit 151 executes a waste paper recycling process (a process according to a flowchart of FIG. 9 described later) for the non-confidential supply unit.

[7. Reproduction processing for the confidential supply department]
FIG. 8 is a flowchart of the reproduction process targeted at the security supply unit. The process according to the flowchart of FIG. 8 is executed by the control unit 151. Here, a case where the supply unit 10a is selected as a confidential supply unit will be described. Hereinafter, the supply unit 10a is also referred to as a confidential supply unit 10a.

  In step S30, the control unit 151 locks the cover 702a of the confidential supply unit 10a with the lock mechanism 703a. As a result, the confidential state in which the waste paper set on the tray 701a cannot be visually recognized and the paper cannot be taken out from the tray 701a is set (state B in FIG. 4).

  In the subsequent step S31, the control unit 151 starts the waste paper recycling process for the confidential supply unit 10a. In step S32, the control unit 151 determines whether or not the residual paper remains in the confidential supply unit 10a. The determination is made based on the detection signal. The control unit 151 proceeds to step S33 when the waste paper remains in the security supply unit 10a, and proceeds to step S50 when the waste paper does not remain in the security supply unit 10a.

  Steps S <b> 33 to S <b> 40 are processes for temporarily stopping the waste paper recycling process for the security supply unit 10 a and releasing the cover 702 a from being fixed. In step S33, the control unit 151 performs the same user (the user who has started the waste paper recycling process for the confidential supply unit 10a) through a new authentication operation (the authentication operation in steps S1 and S3 in FIG. 7 described above). It is determined whether or not is authenticated.

  Then, the control unit 151 proceeds to step S34 when the same user is authenticated, and proceeds to step S32 when the same user is not authenticated. In step S34, the control unit 151 temporarily stops feeding from the confidential supply unit 10a, and in step S35, the cover 702a is released from being locked by the lock mechanism 703a, and the cover 702a is opened and closed. To do.

  As a result, the user who is authenticated as the same user can open the cover 702a, add waste paper to the tray 701a, check the remaining amount of waste paper, and the like. When the opening / closing detection unit 704a detects that the cover 702a is opened in step S36, the control unit 151 transmits data notifying that the cover 702a is opened to the management server 500 in step S37. In the management server 500 that has received this data, the usage information storage unit 510 changes the usage status of the first sheet processing apparatus 100a of the corresponding user in the usage history DB 513 to “suspended”.

  In the next step S38, the control unit 151 determines whether or not the cover 702a of the confidential supply unit 10a is closed based on the detection signal of the open / close detection unit 704a. Then, the control unit 151 proceeds to step 39 when the cover 702a is closed, and fixes the state where the cover 702a is closed by the lock mechanism 703a and returns it to the confidential state.

  In subsequent step S40, the control unit 151 transmits data notifying that the cover 702a is closed to the management server 500. In the management server 500 that has received this data, the usage information storage unit 510 changes the usage status of the first sheet processing apparatus 100a of the corresponding user in the usage history DB 513 to “processing”. Then, in step S41, the control unit 151 resumes paper feeding from the security supply unit 10a and proceeds to step S32.

[8. Recycling of waste paper for non-confidential supply departments]
FIG. 8 is a flowchart of the waste paper recycling process for the non-confidential supply unit. The process according to the flowchart of FIG. 8 is executed by the control unit 151. Here, a case where the supply unit 10a is selected as a confidential supply unit and the supply unit 10b is selected as a non-confidential supply unit will be described. Hereinafter, the supply unit 10b is also referred to as a non-confidential supply unit 10b.

  The control unit 151 does not fix the closed state of the cover 702b by the lock mechanism 703b for the non-confidential supply unit 10b, so that the user can open and close the cover 702b even during the waste paper recycling process. Yes (state B in FIG. 4).

  In step S60 of FIG. 9, the control unit 151 determines whether or not a waste paper recycling process for the confidential supply unit 10a is being executed. The control unit 151 repeats the process of step S60 and enters a standby state when the waste paper recycling process for the confidential supply unit 10a is being executed. On the other hand, when the waste paper recycling process for the confidential supply unit 10a is not executed, the process proceeds to step S61, and the waste paper recycling process for the non-security supply unit 10b is started.

  When the waste paper recycling process for the confidential supply unit 10a is executed by the process of step S60, the waste paper recycling process for the non-security supply unit 10b is not started. Thus, the waste paper set in the confidential supply unit 10a (the waste paper on which confidential information is printed and the confidential information is desired to be promptly processed) is discarded in the non-confidential supply unit 10b. Prior to (discarded paper without confidential information), it is processed with priority. In this case, the security supply unit 10a corresponds to the first set unit of the present invention, and the non-security supply unit 10b corresponds to the second set unit of the present invention.

  In step S62, the control unit 151 determines whether or not the waste paper recycling process for the confidential supply unit 10a is being executed. When the waste paper recycling process for the confidential supply unit 10a is being executed, the control unit 151 proceeds to step S70 and performs the waste paper recycling process for the non-security supply unit 10b. Interrupt.

  As a result, after the waste paper regeneration process for the non-confidential supply unit 10b is started in step S61, when the waste paper regeneration process for the confidential supply unit 10a is started or restarted, in step S70. Then, the waste paper recycling process for the non-confidential supply unit 10b is interrupted. Therefore, the waste paper set in the security supply unit 10a is processed with priority.

  On the other hand, when it is determined in step S62 that the waste paper recycling process for the confidential supply unit 10a is not being executed, the control unit 151 proceeds to step S63, and the waste paper recycling process for the non-security supply unit 10b is performed. Continue. Here, through the processing of step S60, and steps S62 and S70, the waste paper recycling process for the confidential supply unit 10a is prioritized over the waste paper recycling process for the non-security supply unit 10b. The processing corresponds to priority processing control of the present invention.

  In subsequent step S64, the control unit 151 determines whether or not waste paper remains on the tray 701b of the non-confidential supply unit 10b based on the detection signal of the paper detection unit 705b. The control unit 151 proceeds to step S62 when the waste paper remains in the tray 701b of the non-confidential supply unit 10b, and proceeds to step S65 when the waste paper does not remain in the tray 701b.

  In step S <b> 65, the control unit 151 transmits data for notifying that there is no waste paper in the security supply unit 10 b to the management server 500. When the waste paper recycling process for the non-confidential supply unit 10b is completed, the control unit 151 transmits data for notifying the completion of the process to the management server 500 in step S65. In the management server 500 that has received these data, the usage information storage unit 510 changes the usage information of the corresponding first sheet processing apparatus 100a of the user in the usage history DB 513 to “complete”.
