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.

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 the 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 vaporizer-type or hot-air vaporizer-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 coarse crushing unit 12 cuts (crushes) the raw material supplied by the supply unit 10 with a coarse crushing blade 14 to obtain a coarse 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 a piece of paper having a size of 1 to several cm square or less.

The crushing unit 12 has a chute (hopper) 9 that receives the crushing pieces that are cut by the crushing blade 14 and dropped. 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 rough crushing blade 14 adsorb | sucks to the chute | shoot 9 and 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 this 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 part 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 inlet 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 pipe 8 connects the inside of the drum portion 41 and the pipe 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 (separating unit) includes a mesh belt 46 (separating 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.

The mesh belt 46 moves at a constant speed V1 during the normal operation of manufacturing the sheet S. 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.

Therefore, 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 part 48 through the dust collection part 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.

Therefore, 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 conveyance path of the mesh belt 46, air including 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 W1 accumulated on the mesh belt 46. The first web W 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. .

The configuration of the rotating body 49 is arbitrary, but in the present embodiment, the rotating body 49 can have a rotating blade shape having a plate-shaped blade. 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 1 that is peeled from the mesh belt 46 and is transported to generate the subdivided body P.

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 flows an air stream including the subdivided body P, 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 in the tube 54 while mixing the subdivided body P and the additive. 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 to bind 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.

The subdivided body P descending the pipe 7 and the additive supplied by the additive supply unit 52 are sucked into the pipe 54 and pass through the inside of the mixing blower 56 due to the air flow generated by 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 deposition unit 60 introduces the mixture that has passed through the mixing unit 50 from the introduction port 62, loosens the entangled defibrated material (fibers), and 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.

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 suction mechanism 76 sucks the mixture dispersed in the air by the deposition unit 60 onto the mesh belt 72. 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 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 2 that is soft and swelled with a lot of air 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 includes 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 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 W2 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 pressurizes 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 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 2 pressed by the calendar roller 85 to form the sheet S.

Thus, the second web W 2 formed by the stacking unit 60 is pressurized 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.

In addition, the number of the calender rollers 85 included in the pressing unit 82 and the number of the heating rollers 86 included in the heating unit 84 are not particularly limited.

The cutting unit 90 (cutter unit) cuts the sheet S formed by the sheet forming unit 80. In the present embodiment, the cutting unit 90 cuts the sheet S in 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.

Further, in the above configuration, the

humidifying units

210 and 212 may be configured by one ultrasonic humidifier or may be configured by 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. FIG.

Further, the blower included in the sheet processing apparatus 100 described above is not limited to the defibrating unit blower 26, the collection blower 28, the mixing blower 56, the suction blower 77, and the intermediate blower. For example, it is of course possible to provide a blower for assisting each blower described above in the duct.

[1-6. 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.

7 are steps 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 sends 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 registered in the user DB 511 of the management server 500. Authenticate that it 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.

[1-7. 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. Further, the cover 702a is made of an opaque material. As a result, the waste paper set on the tray 701a cannot be visually recognized, read, and determined from the outside. Accordingly, in a confidential state where the paper cannot be taken out from the tray 701a by the lock mechanism 703a (state B in FIG. 4), a higher confidential state is ensured, and leakage of confidential information can be further prevented.

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 S33 to S40 are processes for temporarily stopping the recycling process of the waste paper for the confidential supply unit 10a and releasing the fixing of the cover 702a. 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.

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.

Thus, 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 has been 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.

Steps S50 to S52 are processes when the waste paper recycling process for the confidential supply unit 10a is completed. In step S50, the control unit 151 transmits data for notifying that the waste paper in the confidential supply unit 10a has run out to the management server 500 (corresponding to a predetermined notification of the present invention).

The management server 500 that has received this data refers to the usage history DB 513 and the user DB 511 to determine whether there is a user ID waiting for use of the first sheet processing apparatus 100a. When there is a user ID waiting for use, an e-mail notifying that the first sheet processing apparatus 100a can be used is sent to the e-mail address stored in association with this user ID. Send to.

In subsequent step S51, the control unit 151 switches the lock mechanism 703a to the open state. This eliminates the need for the user to unlock the cover 702b, thereby improving user convenience.

In the next step S52, the control unit 151 transmits data for notifying the completion of processing to the management server 500 when the waste paper recycling process for the confidential supply unit 10a is completed (to the predetermined notification of the present invention). Equivalent to). 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 “completed”.

[1-8. Recycling of waste paper for non-confidential supply departments]
FIG. 9 is a flowchart of the waste paper recycling process for the non-confidential supply unit. The process according to the flowchart of FIG. 9 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 non-confidential supply unit 10b when the cover 702b is closed by the lock mechanism 703b, so that the user can open and close the cover 702b (see B in FIG. 4). Status).

In step S60 in FIG. 9, the control unit 151 determines whether or not the waste paper recycling process for the confidential supply unit 10a is being executed. Then, the control unit 151 repeats the process of step S60 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 has not been executed, the control unit 151 proceeds to step S61 to perform the waste paper recycling process for the non-security supply unit 10b. Start.

When the paper recycling process for the confidential supply unit 10a is being executed by the process of step S60, the paper recycling process for the non-security supply unit 10b is not started. As a result, the waste paper set in the confidential supply unit 10a (the waste paper for which quick processing is desired because of its high density) is changed to the waste paper set for the non-confidential supply unit 10b (the waste paper with low density). Prior to processing, it is processed.

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.

Thus, when the waste paper recycling process for the confidential supply unit 10a is started or restarted after the waste paper recycling process for the non-confidential supply unit 10b is started in step S61, the non-confidential supply is performed. The waste paper recycling process for the section 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.

In subsequent step S64, the control unit 151 determines whether or not waste paper remains in 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 S65, the control unit 151 transmits to the management server 500 data for notifying that there is no waste paper in the non-confidential supply unit 10b. Then, 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 second sheet processing apparatus 100b of the corresponding user in the usage history DB 513 to “complete”.

[2. Sheet Processing Apparatus in Second Embodiment]
FIG. 10 is a schematic diagram illustrating the overall configuration of the sheet processing apparatus according to the second embodiment. FIG. 11 is a flowchart of processing according to the sensitivity of the sheet.

Referring to FIG. 10, the sheet processing apparatus 800 in the second embodiment is a shredder. The sheet processing apparatus 800 includes a supply unit 850 (corresponding to a first setting unit of the present invention) on which waste paper Pa (corresponding to a sheet of the present invention) is set, and a waste paper Pa supplied from the supply unit 850. A first transport path 810, a second transport path 811 and a third transport path 812 are provided.

Drive rollers

801, 802, 803, 804, and 805 are provided in the first transport path 810. A driving roller 806 is provided in the second conveyance path 811, and a driving roller 807 is provided in the third conveyance path 812.

Further, the sheet processing apparatus 800 cuts the waste paper supplied from the image pickup unit 815 and the second transport path 811 that captures the waste paper Pa transported through the first transport path 810 with the first level of fineness. One cutting part 820 is provided. Further, the sheet processing apparatus 800 includes a second cutting unit 821 that cuts the waste paper supplied from the third conveyance path 812 to a second level (a level finer than the first level).

The waste paper that is not cut is discharged from the first transport path 810 to the plain paper box 830 as it is. The waste paper Pb cut by the first cutting unit 820 is discharged to the level 1 box 831, and the waste paper Pc cut by the second cutting unit 821 is discharged to the level 2 box 832. Further, the sheet processing apparatus 800 includes a control device 860 that controls the overall operation of the sheet processing apparatus 800.

Here, the first conveyance path 810, the second conveyance path 811, the third conveyance path 812, the driving rollers 801 to 807, the first cutting unit 820, and the second cutting unit 821 constitute the sheet processing unit of the present invention. The

The supply unit 850 has a configuration (corresponding to the set state switching unit of the present invention) that switches between a confidential state and a non-confidential state, similarly to the

supply units

10a and 10b of the first embodiment described above. Here, the cover 850a is formed of an opaque material. Therefore, the confidential state is a state in which the waste paper Pa fixed with the cover 850a closed cannot be taken out, and is not visible from the outside. Further, the non-confidential state is a state in which the cover 850a is released from being fixed, so that the waste paper Pa can be taken out, and when the cover 850a is opened or the waste paper Pa is taken out, the waste paper Pa is visually recognized, read, It is in a state where discrimination is possible.

Further, the control device 860 includes a main processor, a memory, various interfaces, and the like, similar to the control device 110 of the first embodiment described above. The control device 860 controls the overall operation of the sheet processing apparatus 800 and the authentication unit 861 that performs user authentication by executing a control program for the sheet processing apparatus 800 stored in the memory by the main processor. It functions as the control unit 862.

Further, like the control device 110, the control unit 862 includes a card reader 864 (corresponding to the operation unit of the present invention) used for user authentication and a communication unit 863 for performing communication via a communication network. I have.

When the authentication unit 861 authenticates that the user of the sheet processing apparatus 800 is a specific user (a user permitted to use the sheet processing apparatus 800), the control unit 862 sets the supply unit 850 as a confidential state and discards it. Separate paper discharge.

The control unit 862 images the waste paper Pa supplied from the supply unit 850 to the first conveyance path 810 by the imaging unit 815 in step S80 of FIG. In subsequent step S81, the control unit 862 performs image recognition processing such as OCR (Optical Character Reader) and determines the sensitivity of the information written on the waste paper Pa. Specifically, for example, the control unit 151 determines “sensitive” when a character, symbol, or figure that directly indicates that confidential information such as “confidential” printed on the waste paper Pa is recognized. When a character, symbol, or figure indicating a specific object such as a name, product name, development code, address, or the like such as “OO” is recognized, it is determined as “sensitive”. Further, the control unit 862 determines “no sensitivity” when these characters, symbols, and figures are not recognized. Here, the sensitivity detection unit of the present invention is configured by the configuration in which the imaging unit 815 and the control unit 862 perform image recognition processing to determine the sensitivity.

In subsequent step S82, the control unit 862 determines the presence / absence of confidential information on the waste paper Pa. If the confidential information is present (high confidentiality or low confidentiality), the control unit 862 proceeds to step S83 and has no confidentiality. Sometimes the process proceeds to step S95.

In step S83, the control unit 862 determines whether or not the “confidentiality is high”. If the “confidentiality is high”, the control unit 862 proceeds to a process in step S90 and transfers the waste paper Pa from the third conveyance path 812 to the second. The second cutting unit 821 is supplied to perform level 2 cutting processing (cutting processing finer than level 1). In subsequent step S 91, the control unit 862 discharges the waste paper Pc cut by the level 2 cutting process to the level 2 box 832.

On the other hand, when it is determined in step S83 that “confidentiality is low”, the control unit 862 advances the processing to step S84, supplies the waste paper Pa from the second conveyance path 811 to the first cutting unit 820, and performs level 1 processing. Cutting process (cutting process rougher than level 2) is performed. In step S85, the control unit 862 discharges the waste paper Pb cut by the level 1 cutting process to the level 1 box 831.

Further, in step S95, the control unit 862 discharges the waste paper Pa determined to have no sensitivity from the first transport path 810 to the plain paper box 830 without performing a cutting process.

Thus, the control unit 862 changes the processing content (no cutting, level 1 cutting, level 2 cutting) according to the sensitivity of the waste paper Pa. As a result, the amount of waste paper subjected to the cutting process by the second cutting unit 821 is reduced as compared with the case where the second cutting unit 821 uniformly performs the level 2 cutting process on all the waste paper. be able to. For this reason, it is possible to process the “confidentiality high” waste paper more quickly.

In the second embodiment, as in the first embodiment described above, the communication unit 863 may communicate with the management server to manage the user and the usage information of the sheet processing apparatus 800. Further, even when the authentication unit 861 does not authenticate the user, the supply unit 850 may be set in a confidential state to process the waste paper.

For example, the supply unit 10a may be a confidential supply unit, and the supply unit 10b may be a non-confidential supply unit. In this case, while the waste paper is set in the supply unit 10a, the waste paper regeneration process for the supply unit 10b is prohibited, and the waste paper regeneration process for the supply unit 10a has priority. Executed.

Further, when the power supply to the sheet processing apparatus 100 is interrupted due to a power failure or the like with the cover 702a of the supply unit 10 locked by the lock mechanism 703a, the lock mechanism 703a is maintained in the locked state. It is good also as a structure. According to this configuration, when a power failure or the like occurs, it is possible to prevent the cover 702a from being unlocked and the paper set on the tray 701a to be visually recognized and taken out.

Further, as the sheet processing apparatus of the present invention, the sheet processing apparatus 100 that performs defibration by a dry method is shown. However, as the sheet processing apparatus of the present invention, an apparatus that processes sheets using various reproduction methods is adopted. Can do.

In addition, although the user ID recorded on the ID card is used as the user identification information of the present invention, the user's biological information (fingerprint, iris, etc.) may be used.
