[First Embodiment]
1. Overall Configuration FIG. 1 is a schematic diagram showing a configuration of a sheet manufacturing apparatus 100 according to a first embodiment to which the present invention is applied.
The sheet manufacturing apparatus 100 described in the present embodiment, for example, after used fiber such as confidential paper as a raw material is defibrated and fiberized by dry process, and then pressurized, heated and cut to obtain new paper. It is an apparatus suitable for manufacturing. By mixing various additives with the fiberized raw material, it is possible to improve the bond strength and whiteness of paper products and add functions such as color, fragrance, and flame resistance according to the application. Also good. In addition, by controlling the density, thickness, and shape of the paper, it is possible to manufacture paper of various thicknesses and sizes according to the application, such as office paper and business card paper of standard sizes such as A4 and A3. be able to.

The sheet manufacturing apparatus 100 includes a manufacturing unit 102 (sheet manufacturing unit) and a control device 110. The manufacturing unit 102 manufactures a sheet. The manufacturing unit 102 includes a supply unit 10, a crushing unit 12, a defibrating unit 20, a sorting unit 40, a first web forming unit 45, a rotating body 49, a mixing unit 50, a depositing unit 60, a second web forming unit 70, and a conveyance. A part 79, a sheet forming part 80, and a cutting part 90.

Also, the sheet manufacturing apparatus 100 includes

humidifying units

202, 204, 206, 208, 210, and 212 for the purpose of humidifying the raw material and / or humidifying the space 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 wets water, and supplies humidified air with increased humidity by allowing air to pass through the filter. Further, the

humidifying units

202, 204, 206, and 208 may include a heater (not shown) that effectively increases the humidity of the humidified air.

Moreover, in this embodiment, the humidification part 210 and the humidification part 212 are comprised with an ultrasonic humidifier. In other words, the

humidifying units

210 and 212 have a vibrating unit (not shown) that atomizes water and supplies mist generated by the vibrating unit.

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

The supply unit 10 includes, for example, a plurality of stackers 11 (accommodating units) that accommodate used paper (raw materials). In each stacker 11, old paper is accumulated and accumulated. For example, in the supply unit 10, used paper can be stored in different stackers 11 for each type. The supply unit 10 includes an automatic feeding device that selects any one of the plurality of stackers 11 and sends used paper from the selected stacker 11 to the crushing unit 12. The stacker 11 selected by the supply unit 10 is specified by the control of the control device 110.

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 raw crushed pieces cut by the crushing unit 12 are sandwiched between the rotor and the liner of the defibrating unit 20 and defibrated. The defibrating unit 20 generates an air flow by the rotation of the rotor. With this airflow, the defibrating unit 20 can suck the crushed pieces, which are raw materials, from the tube 2 and convey the defibrated material to the discharge port 24. The defibrated material is sent out from the discharge port 24 to the tube 3 and transferred to the sorting unit 40 through the tube 3.

Thus, the defibrated material generated in the defibrating unit 20 is conveyed from the defibrating unit 20 to the sorting unit 40 by the air flow generated by the defibrating unit 20. Further, in the present embodiment, the sheet manufacturing apparatus 100 includes a defibrating unit blower 26 that is an airflow generation device, and the defibrated material is conveyed to the sorting unit 40 by the airflow generated by the defibrating unit blower 26. The defibrating unit blower 26 is 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 41 (sieving unit) 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 part 41, for example, a metal net, an expanded metal obtained by stretching 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 (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 together with the belt 46 in the direction of arrow V1. The fine particles falling from the mesh belt 46 include defibrated materials that are relatively small or low in density (resin particles, colorants, additives, etc.), and the sheet manufacturing apparatus 100 does not use them for manufacturing the sheet S. It is a removed product.

The mesh belt 46 moves at the speed V1 during the driving operation for manufacturing the sheet S. The conveyance speed V1 of the mesh belt 46 and the start and stop of conveyance by the mesh belt 46 are controlled by the control device 110.

Here, the operation operation is an operation excluding the start control and stop control of the sheet manufacturing apparatus 100 described later, and more specifically, the sheet manufacturing apparatus 100 manufactures a sheet S having a desired 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 unit 48 is connected to the dust collection unit 27 (dust collection device) via the tube 23. The dust collection unit 27 separates the fine particles from the airflow. A collection blower 28 is installed downstream of the dust collection unit 27, and the collection blower 28 functions as a dust collection suction unit that sucks air from the dust collection unit 27. Further, the air discharged from the collection blower 28 is discharged out of the sheet manufacturing 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 is possible to suppress the first selected item from adhering to the rotating body 49 and the inner wall of the housing part 43 due to the electrostatic force. In addition, the removal object can be efficiently sucked by the suction portion 48.

In the sheet manufacturing apparatus 100, the configuration for sorting and separating the first defibrated material and the second defibrated material is not limited to the sorting unit 40 including the drum unit 41. For example, you may employ | adopt the structure which classifies the defibrated material processed by the defibrating unit 20 with a classifier. As the classifier, for example, a cyclone classifier, an elbow jet classifier, or an eddy classifier can be used. If these classifiers are used, it is possible to sort and separate the first sort and the second sort. Furthermore, the above classifier can realize a configuration in which removed 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 manufacturing apparatus 100 includes a rotating body 49 that divides the first web W1 deposited 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 the resin in a state where the resin can be easily mixed in the mixing unit 50.

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 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 a resin, a tube 54 that communicates with the tube 7 and through which an airflow including the subdivided body P flows, and a mixing blower 56. The subdivided body P is a fiber obtained by removing the removed 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. The additive acts, for example, as a binder that binds the fibers.
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.

As shown in FIG. 2, an additive cartridge 501 (cartridge) for accumulating additives is detachably attached to the additive supply unit 52. The additive supply unit 52 supplies the additive in the additive cartridge 501 to the pipe 54. A configuration may be provided in which the additive cartridge 501 mounted on the additive supply unit 52 is replenished with the additive. The configuration of the additive supply unit 52 will be described later with reference to FIG.

The additive contained in the additive cartridge 501 and supplied by the additive supply unit 52 includes a resin for binding a plurality of fibers. The resin contained in the additive is a thermoplastic resin or a thermosetting resin. For example, AS resin, ABS resin, polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylic resin, polyester resin, polyethylene terephthalate, polyphenylene ether, poly Butylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like. These resins may be used alone or in combination. 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.

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 action of the air flow generated by the mixing blower 56 and / or the rotating part such as the blades of the mixing blower 56, and this mixture (the first sort and the addition) is mixed. Mixture) 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 deposits the defibrated material that has been defibrated by the defibrating unit 20. More specifically, the depositing unit 60 introduces the mixture that has passed through the mixing unit 50 from the introduction port 62, loosens the entangled defibrated material (fibers), and lowers it while dispersing it in the air. Furthermore, when the additive resin supplied from the additive supply unit 52 is fibrous, the deposition unit 60 loosens the entangled resin. Thereby, the deposition unit 60 can deposit the mixture on the second web forming unit 70 with good uniformity.

The accumulation unit 60 includes a drum unit 61 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 accumulates the passage thing which passed the accumulation part 60, and forms the 2nd web W2. The 2nd web formation part 70 has the mesh belt 72, the roller 74, and the suction mechanism 76, for example. The deposition unit 60 and the second web forming unit 70 correspond to a web forming unit. The drum portion 61 corresponds to a sieve portion, and the second web forming portion 70 (particularly, the mesh belt 72) corresponds to a deposition portion.

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 V2 in the drawing by the movement of the rollers 74. The mesh belt 72 is made of, for example, metal, resin, cloth, or non-woven fabric. The surface of the mesh belt 72 is configured by a net having openings of a predetermined size. Among the fibers and particles descending from the drum unit 61, fine particles having a size that passes through the mesh drops to the lower side of the mesh belt 72, and fibers having a size that cannot pass through the mesh are deposited on the mesh belt 72. 72 is conveyed in the direction of the arrow. During the driving operation for manufacturing the sheet S, the mesh belt 72 moves at a constant speed V2. The driving operation is as described above.

The moving speed V2 of the mesh belt 72 can be regarded as a speed at which the second web W2 is conveyed, and the speed V2 can be referred to as a conveying speed of the second web W2 in the mesh belt 72.

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

The mixture dispersed in the air by the deposition unit 60 is sucked onto the mesh belt 72 by the suction mechanism 76. Thereby, formation of the 2nd web W2 on the mesh belt 72 can be accelerated | stimulated, and the discharge speed from the deposition part 60 can be enlarged. Furthermore, the suction mechanism 76 can form a downflow in the dropping path of the mixture, and can prevent the defibrated material and additives from being entangled during the dropping.
The suction blower 77 (deposition suction unit) may discharge the air sucked from the suction mechanism 76 out of the sheet manufacturing apparatus 100 through a collection filter (not shown). Alternatively, the air sucked by the suction blower 77 may be sent to the dust collecting unit 27 and the removed matter contained in the air sucked by the suction mechanism 76 may be collected.

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

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

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

The sheet manufacturing apparatus 100 is provided with a transport unit 79 that transports 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 an intermediate blower 318 (FIG. 3), and generates an upward airflow on the mesh belt 79a by the suction force of the intermediate blower 318. 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 roller 79b, and conveys the second web W2 to the sheet forming unit 80.
Thus, the conveyance unit 79 peels and conveys the second web W2 formed on the mesh belt 72 from the mesh belt 72.

The sheet forming unit 80 forms the sheet S from the deposit accumulated in the accumulation unit 60. More specifically, the sheet forming unit 80 forms the sheet S by pressurizing and heating the second web W2 (deposit) deposited on the mesh belt 72 and conveyed by the conveying unit 79. In the sheet forming unit 80, the fibers of the defibrated material included in the second web W2 and the additive are heated to bind the plurality of fibers in the mixture to each other via the additive (resin). .

The calendar roller 85 is rotated by the driving force of the pressurizing unit driving motor 335 and conveys the second web W 2 having a high density 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 heater. 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. One of the pair of heating rollers 86 is a driving roller driven by a heating unit driving motor 337 (FIG. 3), and the other is a driven roller. The heating roller 86 heats the sheet S pressed by the calendar roller 85 to form the sheet S. The heating roller 86 is rotated by the driving force of the heating unit driving motor 337 and conveys the 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.

Further, in the process of manufacturing the sheet S by the sheet manufacturing apparatus 100, the boundary between the second web W2 and the sheet S is arbitrary. In the present embodiment, in the sheet forming unit 80 that processes the second web W 2 and forms it on the sheet S, the second web W 2 is pressed by the pressing unit 82, and the second web pressed by the pressing unit 82 is used. Further, the sheet heated by the heating unit 84 is called a sheet S. In other words, a sheet in which fibers are bound by an additive is referred to as a sheet S. The sheet S is conveyed to the cutting unit 90.

The cutting unit 90 cuts the sheet S formed by the sheet forming unit 80.

FIG. 5 is a diagram showing an example of a screen displayed by the display panel 116, and shows an operation screen 160 for a user (operator) operating the sheet manufacturing apparatus 100 to perform an operation.

The operation screen 160 of FIG. 5 is displayed on the display panel 116 after the sheet manufacturing apparatus 100 is turned on, and continues while the sheet manufacturing apparatus 100 manufactures the sheet S or in a standby state to be described later. May be displayed.

The operation screen 160 includes an operation instruction unit 161, a cartridge information display unit 162, a sheet setting unit 163, and a notification unit 164. The operation instruction unit 161 and the sheet setting unit 163 constitute a GUI for a user to perform an operation. By displaying the operation screen 160 on the display panel 116, the touch sensor 117 constitutes a reception unit together with the operation detection unit 153 (FIG. 4).

The operation instruction unit 161 includes a start instruction button 161a that functions as a button (operation unit) for instructing the operation of the sheet manufacturing apparatus 100, a stop instruction button 161b, an interruption instruction button 161c, and a standby instruction button 161d.

The sheet setting unit 163 includes a color setting unit 163a, a thickness setting unit 163b, and a raw material setting unit 163c that function as buttons (operation units) for instructing conditions of the sheet S manufactured by the sheet manufacturing apparatus 100.

The operation units arranged in the operation instruction unit 161 and the sheet setting unit 163 may be installed in the casing of the sheet manufacturing apparatus 100 as physical buttons. In the present embodiment, as an example, an example will be described in which each operation unit is provided as a GUI (icon) using the display panel 116 and the touch sensor 117.

The color setting unit 163a is an operation unit for designating the color of the sheet S. In the example of FIG. 5, when the user operates the color setting unit 163a, the color of the sheet S can be selected from a plurality of preset colors by a pull-down menu. The control unit 150 acquires the color selected by the operation of the color setting unit 163a by the operation detection unit 153. The drive control unit 156 uses the type of additive to be used and a plurality of types of additives among the additives in the additive cartridge 501 mounted on the additive supply unit 52 corresponding to the selected color. The proportion of each additive is determined. The drive control unit 156 determines the amount of additive to be supplied from each additive cartridge 501 based on the type of additive to be used and the ratio of each additive when a plurality of types of additives are used. The additive supply motor 317 is controlled based on the determined amount.

The thickness setting unit 163b is an operation unit for designating the thickness of the sheet S. In the example of FIG. 5, when the user operates the thickness setting unit 163b, the thickness of the sheet S can be selected from a plurality of preset thicknesses by a pull-down menu. The control unit 150 obtains the thickness selected by the operation of the thickness setting unit 163b by the operation detection unit 153. The drive control unit 156 corresponds to the selected thickness, the thickness of the second web W2 deposited on the mesh belt 72 in the deposition unit 60, and / or the load applied to the second web W2 by the pressurization unit 82, and the like. Determine the conditions. The drive control unit 156 controls the rotation speed of the drum drive motor 331, the rotation speed of the belt drive motor 333, the operation condition of the pressure unit drive motor 335, and the like according to the determined conditions.

The raw material setting unit 163c is an operation unit for designating a raw material used for manufacturing the sheet S. In the example of FIG. 5, when the user operates the material setting unit 163c, the type of the material of the sheet S can be selected from a plurality of preset types by a pull-down menu. The raw materials that can be selected by the raw material setting unit 163 c are raw materials that the supply unit 10 stores in the stacker 11. That is, the selection in the raw material setting unit 163 c corresponds to the selection of the stacker 11 that feeds out the raw material in the supply unit 10. The control unit 150 acquires the raw material selected by the operation detection unit 153 by operating the raw material setting unit 163c. The drive control unit 156 selects the stacker 11 that stores the selected raw material, and controls the paper feed motor 315 so that the raw material is supplied from the selected stacker 11.

In addition to the above-described buttons, the sheet setting unit 163 may include a button for specifying the number of sheets S to be manufactured and a button for specifying the size (size) of the sheet S. A button for designating a condition related to S may be arranged.

The start instruction button 161a is a button for instructing the start of manufacturing the sheet S. For example, the start instruction button 161 a is operated after a condition related to the sheet S is designated by an operation of the sheet setting unit 163, and instructs the start of manufacture of the sheet S based on the designated condition. In the sheet setting unit 163, a default specified value is provided in advance, and when the start instruction button 161a is operated in a state where the sheet setting unit 163 is not operated, the sheet manufacturing apparatus 100 sets the default specified value. Based on this, the production of the sheet S may be started.

The stop instruction button 161b is a button for instructing to stop the operation of the sheet manufacturing apparatus 100. The casing of the sheet manufacturing apparatus 100 may be provided with a power switch (not shown) for turning on / off the power of the sheet manufacturing apparatus 100 separately from the display panel 116. In this case, the stop instruction button 161b functions as a button for instructing to stop the sheet manufacturing apparatus 100. However, the stop instruction button 161b may be configured to instruct power-off of the sheet manufacturing apparatus 100 using the stop instruction button 161b. When the sheet manufacturing apparatus 100 stops manufacturing the sheet S by operating the stop instruction button 161b, the condition relating to the sheet S set by the sheet setting unit 163 is cleared, and the default designated value (initial value) is restored.

The interruption instruction button 161c temporarily stops the production of the sheet S while the sheet production apparatus 100 is producing the sheet S. When the interruption instruction button 161c is operated and the sheet manufacturing apparatus 100 stops manufacturing the sheet S, the condition relating to the sheet S set by the sheet setting unit 163 is held. In this state, when the start instruction button 161a is operated, the control unit 150 starts (restarts) production of the sheet S according to the same conditions as before the interruption instruction button 161c is operated by the sheet manufacturing apparatus 100.

The standby instruction button 161d is a button for instructing a shift to a standby state to be described later in a state where the sheet manufacturing apparatus 100 is not manufacturing the sheet S, that is, in a stopped state.

A series of operations for manufacturing the sheet S by the sheet manufacturing apparatus 100 is referred to as a “job”. The job refers to an operation of manufacturing the sheet S having a condition designated by an operation of the sheet setting unit 163 or a default value. Specifically, from the start of the operation in response to the operation of the start instruction button 161a until the completion of the production of the number of sheets S designated by the operation of the sheet setting unit 163, or the operation of the stop instruction button 161b The operation up to stopping by is called a job. When the number of sheets S to be manufactured is designated, the end of the job is clearly specified. When the stop instruction button 161b is operated without specifying the number of sheets S, or when the stop instruction button 161b is operated before the manufacture of the specified number of sheets S is completed, there is no setting in advance. The job ends. When the interruption instruction button 161c is operated, the sheet manufacturing apparatus 100 interrupts the job but does not end it. For this reason, when the start instruction button 161a is operated after the manufacture of the sheet S is stopped in accordance with the operation of the interruption instruction button 161c, the sheet manufacturing apparatus 100 resumes the manufacture of the sheet S, specifically, the interruption. The sheet S is manufactured under the same conditions as before the operation of the instruction button 161c. That is, the interruption instruction button 161c temporarily stops the job, but the job continues if the start instruction button 161a is operated thereafter.

The cartridge information display unit 162 is a display unit that displays information about the additive cartridge 501 mounted (set) in the additive supply unit 52. The cartridge information display unit 162 displays an image simulating the additive cartridge 501 corresponding to the number of additive cartridges 501 that can be attached to the additive supply unit 52. In the cartridge information display unit 162, information indicating the color of the additive and the remaining amount of the additive contained in the additive cartridge 501 is displayed as text or an image corresponding to each image of the additive cartridge 501. . When the number of additive cartridges 501 attached to the additive supply unit 52 is smaller than the number that can be attached, an image corresponding to the additive cartridge 501 that is not attached is displayed as a blank.

The notification unit 164 is a display area in which the content notified to the user is displayed as text or an image. The notification unit 164 displays, for example, a message requesting replacement of the additive cartridge 501.

FIG. 6 is a diagram showing an example of data read from the IC by the IC reading unit 119, and particularly shows an example of temperature data of the additive. In the example shown in FIG. 6, the additive cartridge 501 is distinguished by the color of the additive contained in the additive cartridge 501. In this example, temperature data “Th11” is acquired from the IC 521 of the yellow (YELLOW in the drawing) additive cartridge 501. Further, “Th12” is acquired from the IC 521 of the magenta additive cartridge 501, and “Th13” is acquired from the IC 521 of the cyan additive cartridge 501. Further, “Th14” is acquired from the IC 521 of the white (WHITE) additive cartridge 501, and “Th15” is acquired from the IC 521 of the plain (PLAIN) additive cartridge 501. Th11, Th12, Th13, Th14, and Th15 are numerical values and codes indicating specific temperatures or temperature ranges, respectively. These temperatures are temperatures set in the heating unit 84 so that the resin contained in each additive is melted in an appropriate state, the fibers are bonded with a preferable strength, and good color development is obtained. When the sheet S is manufactured, the control unit 150 specifies the additive used for manufacturing the sheet S, and then, based on the temperature data read from the IC 521 of the additive cartridge 501 containing the specified additive, A heating temperature of 84 is set. Thereby, the 2nd web W2 can be heated in suitable temperature in the heating part 84, and the high quality sheet | seat S can be manufactured. Although the specific temperature of Th11 to Th15 varies depending on the specific properties of the additive, the additive is not practically melted at a temperature close to room temperature, and thus is higher than the so-called room temperature. For example, it is not uncommon for the temperature to exceed 100 degrees Celsius.

The drive control unit 156 of the control unit 150 (FIG. 4) uses an additive to be used from among the additive cartridges 501 attached to the additive supply unit 52 based on the contents input on the operation screen 160 (FIG. 5). The cartridge 501 is specified. Specifically, based on the color specified by the operation of the color setting unit 163a of the sheet setting unit 163 and the type of raw material specified by the operation of the raw material setting unit 163c, the type (for example, color) of the additive to be used is selected. Identify and identify an additive cartridge 501 containing the identified type of additive. Further, the drive control unit 156 obtains the amount of additive per unit time supplied from the specified additive cartridge 501 and sets conditions for operating the additive supply motor 317.

The drive control unit 156 acquires the temperature data read from the IC 521 by the data acquisition unit 155, and acquires the temperature data of the additive cartridge 501 to be used.

The reading of the temperature data from the IC 521 can be performed, for example, when the sheet manufacturing apparatus 100 is turned on, or when the additive cartridge 501 is replaced or mounted. When the power of the sheet manufacturing apparatus 100 is turned on, the data acquisition unit 155 detects the presence or absence of the IC 521 by the IC reading unit 119 and reads data from the detected IC 521. Further, when the data acquisition unit 155 detects the mounting of the additive cartridge 501, the IC reading unit 119 reads data from the detected IC 521. The data acquisition unit 155 temporarily stores the read data in the storage unit 140 (or RAM 113) or the like in association with identification information for identifying the IC 521. The identification information of the IC 521 is, for example, an ID unique to the IC 521, is information stored in the storage area of the IC 521, and can be read by the IC reading unit 119 together with various data such as temperature data.

The drive control unit 156 can acquire temperature data corresponding to the additive cartridge 501 designated or selected based on the input of the operation screen 160 from the data acquired by the data acquisition unit 155 and temporarily stored. Further, the data acquisition unit 155 may read temperature data by the IC reading unit 119 at any time under the control of the drive control unit 156.

The heating control unit 157 determines a setting value of the heating temperature in the heating unit 84 based on the temperature data. The heating temperature is a target temperature of the heating roller 86 in the first state in which the sheet S is manufactured. The heating control unit 157 temporarily stores the determined heating temperature in the storage unit 140 (or the RAM 113) or the like as the operating condition of the manufacturing unit 102.

When a plurality of types of additives are selected based on the input on the operation screen 160, the heating control unit 157 acquires temperature data corresponding to each additive, and sets the heating temperature based on the acquired plurality of temperature data. decide. For example, the heating control unit 157 determines the highest temperature among the acquired plurality of temperature data as the heating temperature.
As an example, a case is assumed in which the relationship shown in the following formula (1) is established in the temperature data of each additive shown in FIG.
Th11 <Th12 <Th13 <Th14 <Th15 (1)

For example, when a yellow additive and a cyan additive are used, the heating control unit 157 acquires the temperature data Th11 and the temperature data Th13, and the heating temperature based on the temperature data Th13 which is the higher temperature among them. To decide. In this method, when a plurality of types of additives are used, heating is performed in accordance with an additive that requires heating at a higher temperature, so that all the additives are heated to a necessary temperature or higher. For this reason, the quality degradation of the sheet S due to insufficient heating can be prevented. Further, the heating control unit 157 may determine the heating temperature based on a plurality of temperature data, reflecting the ratio of the usage amount of the plurality of types of additives to be used.

By the way, the sheet manufacturing apparatus 100 can start manufacturing the sheet S by the user operating the operation screen 160, and can receive an input regarding the sheet S through the operation screen 160 during the operation of manufacturing the sheet S. Specifically, after the manufacturing unit 102 starts a job based on the input on the operation screen 160, the input on the operation screen 160 can be accepted before the job is completed. The input received here (new input) includes input related to the color, thickness, and raw material of the sheet S by the sheet setting unit 163. When the operating condition of the manufacturing unit 102 related to the manufacture of the sheet S is changed from the new input during the manufacture of the sheet S (during the execution of the job), the control unit 150 changes to the condition corresponding to the new input. I do.

As an example of changing the operating conditions, the control unit 150 can change the heating temperature of the heating unit 84. In this case, the control unit 150 changes the operation condition without stopping the execution of the job, which is the operation in which the manufacturing unit 102 manufactures the sheet S.

FIG. 7 is a diagram illustrating an example of an operation state of the sheet manufacturing apparatus 100.
In the drawing, the supply unit indicates the supply unit 10, for example, the state of the paper feed motor 315. The crushing unit indicates the crushing unit 12, for example, the state of the crushing unit driving motor 311. The defibrating unit refers to the defibrating unit 20, and specifically refers to the state of the defibrating unit drive motor 313, but may include the operating state of the defibrating unit 20 including the state of the defibrating unit blower 26. The selection unit indicates the selection unit 40, specifically, the state of the drum drive motor. The first web forming unit indicates the first web forming unit 45 and specifically indicates the state of the belt drive motor 327, but may include the operation state of the first web forming unit 45 including the state of the collection blower 28. The rotator indicates the rotation state of the dividing portion drive motor 329 that drives the rotator 49.

The accumulation unit refers to the accumulation unit 60, and specifically refers to the operation state of the drum drive motor 331 that moves the drum unit 61. The second web forming unit refers to the second web forming unit 70, specifically the operation state of the belt drive motor 333, but may be the operation state of the second web forming unit 70 including the suction blower 77. The pressurizing unit refers to the pressurizing unit 82, and specifically refers to the operating state of the pressurizing unit driving motor 335, but may include the state of the load applied by the pressurizing unit 82. The heating unit refers to the heating unit 84, and specifically refers to the operating state of the heating unit drive motor 337 and the state of the heater 339, respectively. The cutting unit refers to the cutting unit 90, and specifically refers to the operation state of the cutting unit drive motor 351, but may include the operation state of a conveyance unit (not shown) that conveys the sheet S in the cutting unit 90. The discharge unit indicates an operation state of a conveyance unit (not shown) that conveys the sheet S to the discharge unit 97. Further, the humidifying heater refers to the state of the humidifying heater 345.

Further, FIG. 7 is not limited to the energized state of each drive unit, but shows a control state in which the control unit 150 drives each unit. For example, ON / OFF for heating of the heating unit 84 indicates whether the control for the heating by the heater 339 is being performed by the control unit 150 rather than ON / OFF of the energization to the heater 339. For this reason, even if there is a moment when the heater 339 is not actually energized, the operation state is ON while the control unit 150 performs control for heating by the heater 339. The same applies to other drive units.

In FIG. 7, a state in which the manufacturing unit 102 manufactures the sheet S at the heating temperature T1 is indicated as “continuous operation (temperature T1)”, and a state in which the sheet S is manufactured at the heating temperature T2 is “continuous”. "During operation (temperature T2)". Further, the operation state during the change of the heating temperature from the temperature T1 to the temperature T2 is indicated as “at the time of temperature change”.
As shown in FIG. 7, not only “at the time of continuous operation (temperature T1)” and “at the time of continuous operation (temperature T2)” but also “at the time of temperature change”, each drive unit of the manufacturing unit 102 is maintained ON. The The manufacturing unit 102 supplies additives to the raw material supplied by the supply unit 10, the defibrated material defibrated by the defibrating unit 20, the first web W 1, the subdivided body P, and the subdivided body P when “temperature change”. The conveyance of the mixture in which the additive is mixed in the unit 52, the second web W2, and the sheet S is continuously executed. In addition, the manufacturing unit 102 continuously performs the processing for these even when “temperature change”.

FIG. 8 is a timing chart showing an operation example of the sheet manufacturing apparatus 100, and particularly shows a change in the temperature of the heating roller 86. The vertical axis in FIG. 8 indicates the temperature of the heating roller 86. This temperature is a temperature detected by the temperature sensor 309, for example. The horizontal axis shows the passage of time.

The temperature T1 on the vertical axis is a temperature suitable for manufacturing the sheet S, and is a target temperature set by the heating control unit 157 according to the conditions of the sheet S to be manufactured. The temperature T2 is a temperature set by the heating control unit 157 as a target temperature for maintaining the temperature of the heating roller 86 in the second state. On the other hand, T0 is the ambient temperature of the place where the sheet manufacturing apparatus 100 is installed.

In the timing chart of FIG. 8, a temperature pattern G indicates a temperature change when the heating temperature is changed from the temperature T1 to a temperature T2 higher than the temperature T1 under the control of the heating control unit 157. The time t1 is the timing when the condition input by the operation of the sheet setting unit 163 is confirmed, for example, the timing when the start instruction button 161a is operated after the operation of the sheet setting unit 163. Time t2 is timing when the heating temperature, that is, the temperature of the heating roller 86 reaches the temperature T2. That is, the period TE1 from time t1 to time t2 is the time required to realize the set condition.

In the period TE1 of FIG. 8, since the temperature of the heating roller 86 is lower than the temperature T2, the sheet S heated by the heating roller 86 in this period TE1 is heated at a lower temperature than the set temperature. . For this reason, the sheet S that has passed through the heating unit 84 in the period TE1 may have a different property from the set type of sheet S. For example, when the type of additive added by the additive supply unit 52 is changed at time t1, a temperature T2, which is a heating temperature suitable for the additive after change, is set at time t1. The sheet S containing the changed additive is desirably heated at a temperature T2.

Therefore, when the heating temperature of the heating unit 84 is changed, the sheet manufacturing apparatus 100 distinguishes the sheets S manufactured until the heating temperature of the heating unit 84 reaches the set temperature after the change.

Also, when the type and amount of the additive are changed at time t1, it takes time until the sheet S containing the changed additive is discharged to the discharge unit 97. When the sheet manufacturing apparatus 100 changes the type and amount of the additive to be mixed in the additive supply unit 52, the sheet discharged before the sheet S containing the changed additive is discharged from the discharge unit 97. S is distinguished.

FIG. 9 is a schematic diagram of the manufacturing process of the sheet S of the sheet manufacturing apparatus 100 and shows the process from the addition of the additive by the additive supply unit 52 to the discharge.
A symbol M shown in the figure indicates a mixture in which an additive is mixed into the subdivided body P in the additive supply unit 52. The mixture M, the second web W2, and the sheet S are collectively referred to as a conveyed object FM.

FIG. 9 shows a plurality of stages PR1, PR2, PR3, PR4, PR5, PR6, PR7, PR11 in the manufacturing process of the sheet S. The stage PR1 is a stage in which the additive is mixed with the subdivided body P in the additive supply unit 52. Stage PR11 is a process of depositing the mixture M on the mesh belt 72, stage PR2 indicates the start of stage PR11, and stage PR3 indicates the end of stage PR11. Stage PR4 is a stage in which the pressure unit 82 pressurizes the second web W2 to form the sheet S, and stage PR5 is a stage in which the sheet S is heated by the heating unit 84. Step PR6 is a step of cutting the sheet S by the first cutting unit 92, and step PR7 is a step of cutting the sheet S by the second cutting unit 94. In addition, although the deposition process of the mixture M is performed continuously, the end of the deposition process corresponding to the length of one sheet S is illustrated as a stage PR3 in FIG. 9 for convenience of understanding. Prior to stage PR2, the mixture M is transported through the tube 54 by an air flow and is not in the form of a sheet or web, but for convenience of understanding, the mixture M is illustrated in the form of a band in FIG.

When the drive control unit 156 changes the type and / or amount of the additive mixed in the additive supply unit 52 based on the input to the operation screen 160, the type and amount of the additive are changed in step PR1. At this time, the transported object FM including the additive before the change exists between the stages PR1 to PR7. Of the transported object FM, the sheet S existing between the stage PR5 to the stage PR7 contains the additive before the change and is heated at the temperature T1 suitable for the additive before the change. Satisfies the quality of the sheet S. On the other hand, the to-be-conveyed object FM located between the stages PR1 to PR5 includes the material before change and is not heated by the heating unit 84. When the transported object FM is discharged as the sheet S, the quality of the sheet S may not satisfy both the type of the sheet S before and after the change.

The control unit 150 converts the conveyed object FM existing in the section L1 between the stages PR1 to PR5 at the timing of changing the type and amount of the additive, the sheet S existing at the stage after the stage PR5 at this timing, and A distinction is made from materials in a stage prior to stage PR1. Specifically, the length of the section L1 or the conveyance time corresponding to the length of the section L1 is included in the setting data 121 and stored in advance.

In the sheet manufacturing apparatus 100, the type and amount of the additive are changed corresponding to the type of the sheet S after the change in response to the change of the type of the sheet S by the input of the operation screen 160, and the addition after the change Corresponding to the type of object, the heating temperature is changed based on the temperature data. For this reason, the setting of the kind and amount of the additive added in the additive supply unit 52 and the setting of the heating temperature are changed almost simultaneously. However, the drive control unit 156 operates the supply adjustment unit 52b of the additive supply unit 52 to change the type and amount of the additive, and the heating control unit 157 performs a series of processes to change the temperature of the heating roller 86. Require different times and do not necessarily start or end at the same time. Therefore, control performed by the control unit 150 for these timings will be described.

10 and 11 are schematic views showing changes in the sheet manufactured by the sheet manufacturing apparatus 100. FIG. 10 shows the sheet S discharged from the manufacturing unit 102, and FIG. 10A shows the correspondence between the timing at which the heating temperature of the heating unit 84 changes and the type of the sheet S. FIG. 10B shows the correspondence between the timing at which the additive added by the additive supply unit 52 changes and the type of the sheet S.

In FIG. 10, symbols B1, B2, and B3 indicate specific positions on the sheet S. Reference numeral B 1 indicates the position of the sheet S that has passed through the heating unit 84 at the timing when the heating control unit 157 starts changing the heating temperature of the heating unit 84. Reference sign B2 indicates the position of the sheet S that has passed through the heating unit 84 at the timing when the change in the heating temperature of the heating unit 84 is completed.

Therefore, the position B1 is a boundary between the sheet S11 heated at the heating temperature (for example, temperature T1) before the change and the sheet S13 heated at a heating temperature higher than the temperature T1 and lower than the temperature T2. Further, the position B2 is a boundary between the sheet S13 heated at a heating temperature lower than the temperature T2 and the sheet S12 heated at the temperature T2.

Focusing on the additive, position B3 indicates the position on the sheet S including the material positioned in the stage PR1 (FIG. 9) at the timing when the additive supply unit 52 changes the type and amount of the additive. The position B3 is a boundary between the sheet S21 including the additive before the change and the sheet S22 including the additive after the change.

As described above, when the type of the sheet S to be manufactured is changed, both the type and / or amount of the additive and the heating temperature of the heating unit 84 need to be changed. In order to realize the preferable quality of the sheet S, two conditions are necessary: (1) containing a set additive, and (2) heating at a set heating temperature.

As shown in FIG. 10, when the timing at which the temperature of the heating unit 84 changes does not coincide with the timing at which the additive supply unit 52 switches the additive, the sheet manufacturing apparatus 100 performs the above (1) and (2). A sheet S satisfying both conditions is distinguished from other sheets S.
In the example of FIG. 10, before the position B1 (downstream side), the heating temperature corresponds to the sheet S11, and the additive corresponds to the sheet S21. Accordingly, the sheet S before the position B1 is the type of sheet S before the change (hereinafter referred to as the sheet S1).

Further, after the position B2 (upstream side), the heating temperature corresponds to the sheet S12, and the additive corresponds to the sheet S22. Therefore, it can be said that the sheet S after the position B2 is the type of sheet S after the change (hereinafter referred to as the sheet S2).
On the other hand, in the sheet S3 between the positions B1 and B2, the coincidence between the type of additive and the temperature is unknown, and both the conditions (1) and (2) are not satisfied. In particular, the condition (2) is not satisfied. For this reason, the sheet manufacturing apparatus 100 sets the sheet S3 as a different type of sheet from the sheets S1 and S2.

FIG. 11 shows the sheet S discharged from the manufacturing unit 102 as in FIG. 10, and FIG. 11A shows the correspondence between the timing at which the heating temperature of the heating unit 84 changes and the type of the sheet S. FIG. 11B shows the correspondence between the timing at which the additive added by the additive supply unit 52 changes and the type of the sheet S.
The example shown in FIG. 11 shows an example in which the timing at which the additive is changed in the additive supply unit 52 is after the timing at which the heating temperature of the heating unit 84 is changed. In this example, the position B3 is located before the position B2. Accordingly, it is the sheet S1 before the position B1 and the sheet S2 before the position B3 that satisfy both the conditions (1) and (2), and the sheet between the positions B1 and B3 is the sheet S2. Differentiated.

The drive control unit 156 can control the discharge switching unit 903 of the discharge unit 97 to discharge, for example, the sheets S1, S2, and S3 to different discharge trays 902 and store them. The positions B1, B2, and B3 on the sheet S can be specified by the control unit 150 based on the timing at which the control unit 150 performs control and the conveyance speed of the second web W2 and the sheet S. Accordingly, the drive control unit 156 can control the discharge switching unit 903 to identify the sheet S discharged before and after the positions B1, B2, and B3 in the discharge unit 97, and perform switching by the discharge switching unit 903. it can.

FIG. 12 is a flowchart showing the operation of the sheet manufacturing apparatus 100. FIGS. 13, 14 and 15 are flowcharts showing the operation of the sheet manufacturing apparatus 100, and particularly show the processing of FIG. 12 in detail.

When the sheet manufacturing apparatus 100 is powered on (step ST11), the display control unit 152 displays the operation screen 160 on the display panel 116 (step ST12). The operation detection unit 153 detects an operation on the operation screen 160 by the user, performs a process of receiving an input by this operation, and acquires the operation content (step ST13).

The control unit 150 sets the operating conditions of the sheet manufacturing apparatus 100 based on the operation content acquired by the operation detection unit 153 in step ST13 by the functions of the drive control unit 156 and the heating control unit 157 (step ST14).

The processing executed in step ST14 is shown in detail in FIG.
Based on the operation content acquired in step ST13, the control unit 150 identifies the additive cartridge 501 to be used among the additive cartridges 501 mounted on the additive supply unit 52 (step ST31). For example, based on the color specified by the operation of the color setting unit 163a of the sheet setting unit 163 and the type of raw material specified by the operation of the raw material setting unit 163c, the type of additive to be used is specified, and the specified type The additive cartridge 501 containing the additive is specified. Further, the control unit 150 obtains the amount of additive per unit time supplied from the identified additive cartridge 501 and sets conditions for operating the additive supply motor 317.

The control unit 150 acquires temperature data read by the IC reading unit 119 from the IC 521 mounted on the additive cartridge 501 specified in step ST31 (step ST32).

The control unit 150 determines the heating temperature of the heating unit 84 based on the temperature data acquired in step ST32 (step ST33).
In step ST33, when a plurality of types of additives are used, the control unit 150 acquires temperature data corresponding to each additive, and determines the heating temperature based on the acquired plurality of temperature data.

In step ST33, the example in which the heating temperature is determined based on the temperature data read from the IC 521 of the additive cartridge 501 containing the additive to be used has been described, but corresponds to the raw material specified by the raw material setting unit 163c. The heating temperature may be set. For example, for each type of raw material, the heating temperature of the heating unit 84 suitable for the raw material may be included in the setting data 121 and stored in advance. In this case, the control unit 150 acquires the heating temperature corresponding to the raw material specified by the raw material setting unit 163c from the setting data 121. The control part 150 should just set the temperature of the higher side among the highest temperature among the temperature data corresponding to the additive to be used, and the heating temperature corresponding to a raw material to a heating temperature.

The control unit 150 sets the heating temperature determined in step ST33 as an operating condition of the manufacturing unit 102 (step ST34). The set operating conditions are stored in the storage unit 140, for example.

Returning to FIG. 12, the control unit 150 executes the activation sequence (step ST15). In the activation sequence, the control unit 150 executes processing for initializing various sensors connected to the sensor I / F 114 and starting detection. The activation sequence includes initialization of the operation of each driving unit connected to the driving unit I / F 115 and control for shifting each driving unit to a state where the manufacture of the sheet S can be started. In this activation sequence, the control unit 150 switches the power source of the heater 339 to ON and starts temperature increase. In addition, the control unit 150 switches the power source of the humidifying heater 345 to ON and starts temperature increase.

The controller 150 determines whether or not the temperature of the heater 339 has reached the heating temperature set in step ST14, which is the target temperature (step ST15), and while the heating temperature has not been reached (step ST15; No). ,stand by. During this standby, the control unit 150 can of course control other drive units.

When it is determined that the temperature of the heater 339 has reached the target temperature (step ST15; Yes), the control unit 150 shifts the operating state of the sheet manufacturing apparatus 100 to the first state and starts manufacturing the sheet S, that is, starts a job. (Step ST17).

After starting the manufacture of the sheet S, the control unit 150 detects an input that causes a change in the operating condition of the manufacturing unit 102 by an operation on the operation screen 160 (step ST18).
Specifically, the control unit 150 detects an input for changing the type of the sheet S through the operation screen 160. If there is no input (step ST18; No), the control unit 150 determines whether or not the job is completed (step ST19). For example, when the number of sheets S to be manufactured is specified in step ST13 and the manufacturing of the specified number of sheets S is completed, the job is completed. The job is also completed when the stop instruction button 161b is operated.

If the job is not completed (step ST19; No), the control unit 150 returns to step ST18. When the job is completed (step ST19; Yes), the control unit 150 executes a stop sequence and shifts the sheet manufacturing apparatus 100 to a stop state (step ST20). In the stop sequence, each drive unit of the manufacturing unit 102 is stopped.

Note that the stop sequence executed in step ST20 can be executed as an interrupt process when the stop instruction button 161b is operated.

In addition, when an input regarding the type of the sheet S is detected by operation of the sheet setting unit 163 during the execution of the job (step ST18; Yes), the control unit 150 changes the operating condition of the manufacturing unit 102. Is performed (step ST21).

The condition changing process executed in step ST21 is shown in detail in FIG.
The operation detection unit 153 performs a process of receiving an input by a user operation, and acquires operation contents (step ST41).

Based on the operation content acquired by the operation detection unit 153 in step ST41, the control unit 150 identifies the additive cartridge 501 to be used among the additive cartridges 501 attached to the additive supply unit 52 (step ST42). . This process is the same as step ST31. The control unit 150 acquires temperature data read by the IC reading unit 119 from the IC 521 mounted on the additive cartridge 501 specified in step ST42 (step ST43). This process is the same as step ST32.

The control unit 150 determines the heating temperature of the heating unit 84 based on the temperature data acquired in step ST43 (step ST44). This process is the same as step ST33. For example, the control part 150 may determine heating temperature according to the raw material supplied from the supply part 10, as demonstrated by step ST33.

Based on the type of cartridge specified in step ST42 and the amount of additive supplied from each cartridge and / or the heating temperature determined in step ST44, the controller 150 changes the setting of the operating condition of the manufacturing unit 102 ( Step ST45).

Here, the control unit 150 determines whether or not the setting related to the material is changed in step ST45 (step ST46). Specifically, the material includes an additive added by the additive supply unit 52 and a raw material supplied from the supply unit 10.
When the setting regarding a material is changed (step ST46; Yes), the control part 150 reflects the setting changed regarding supply of the additive from the additive supply part 52, and performs supply of an additive (step). ST47). In step ST47, the change of the setting regarding the type and amount of the additive is reflected, and the supply based on the changed setting is started.
The control unit 150 records the timing when the supply of the additive is changed (step ST48), and proceeds to step ST49. In step ST48, the control unit 150 causes the storage unit 140 to store data indicating the change timing, for example. For example, you may start counting the elapsed time after making a change. When it determines with the setting regarding material not having been changed by step ST45 (step ST46; No), the control part 150 transfers to step ST49.

In step ST49, the control unit 150 determines whether or not the setting related to the heating temperature of the heating unit 84 has been changed in step ST45 (step ST49). When the setting relating to the heating temperature is changed (step ST49; Yes), the control unit 150 controls the heater 339 to start the temperature change of the heating roller 86 (step ST50). Here, the control part 150 records the timing which started the temperature change (step ST51). In step ST51, for example, the control unit 150 causes the storage unit 140 to store data indicating the change timing. Further, for example, counting of the elapsed time from the start of temperature change may be started.

The control unit 150 determines whether or not the temperature of the heater 339 has reached the target temperature (step ST52), and stands by while not reaching the heating temperature (step ST52; No). During this standby, the control unit 150 can of course control other drive units.
When it determines with the temperature of the heater 339 having reached target temperature (step ST52; Yes), the control part 150 records the timing which temperature change was complete | finished (step ST53), and returns to FIG. In step ST53, the control unit 150 causes the storage unit 140 to store data indicating the change timing, for example. Further, for example, counting of the elapsed time from the end of the change may be started. Moreover, when it determines with the setting regarding the heating temperature of the heating part 84 not having been changed (step ST49; No), it returns to FIG.

Returning to FIG. 12, the control unit 150 starts the discharge control (step ST22), and proceeds to step ST19. As shown in FIGS. 10 and 11, the discharge control is performed by changing the type of sheet S1 before the change, the type of sheet S2 after the change, and a sheet S3 of a type different from the sheets S1 and S2 into the discharge unit. 97 is a control for accommodating the paper in different discharge trays 902.

FIG. 15 is a flowchart showing the discharge control in detail.
The control unit 150 acquires data indicating each timing recorded in the process shown in FIG. 14 (step ST61). Specifically, the recording of the timing of changing the supply of the additive recorded in step ST48, the recording of the timing of starting the temperature change recorded in step ST51, and the timing of the end of the temperature change recorded in step ST53. Get a record.

The control unit 150 identifies the boundaries of the sheets S1, S2, and S3 discharged from the cutting unit 90 to the discharge unit 97 based on the data acquired in step ST61 (step ST62). For example, the control unit 150 identifies the positions B1, B2, and B3 shown in FIGS. 10 and 11, and based on these positions, the boundary between the sheet S1 and the sheet S3, and the boundary between the sheet S3 and the sheet S2. Specify the position of.

The control unit 150 determines the timing at which the boundary specified in step ST62 passes through the cutting unit 90 (step ST63). Further, based on the timing determined in step ST63, the control unit 150 identifies the timing for switching the discharge tray 902 by the discharge switching unit 903 (step ST64).

When the timing determined in step ST63 does not coincide with the timing of cutting the sheet S by the cutting unit 90, the control unit 150 specifies the switching timing so that the sheet S3 is not mixed into the sheet S1 and the sheet S2 in step ST64. . This timing mismatch means that the boundary between the sheet S1 and the sheet S3 and the boundary between the sheet S3 and the sheet S2 are shifted from the cutting position where the cutting unit 90 cuts the sheet S. More specifically, it means that the cut sheet S includes both the sheet S1 and the sheet S3. The same applies to the boundary between the sheet S3 and the sheet S2.

Among the sheets S cut by the cutting unit 90, the sheet S including both the sheet S1 and the sheet S3 and the sheet S including both the sheet S3 and the sheet S2 are referred to as mixed sheets. The control unit 150 specifies the switching timing so that the mixed sheet is not stored in the discharge tray 902 that stores the sheet S1. Similarly, the control unit 150 specifies the switching timing so that the mixed sheet is not stored in the discharge tray 902 that stores the sheet S2. The control unit 150 may store the mixed sheet in the same discharge tray 902 as the sheet S3. Further, the control unit 150 may control the discharge unit 97 so that the mixed sheet is accommodated in a discharge tray 902 different from any of the sheets S1, S2, and S3.

The control unit 150 controls the discharge switching unit 903 to switch the discharge tray 902 at the timing specified in step ST64 (step ST65). After switching the discharge tray 902 corresponding to both the boundary between the sheet S1 and the sheet S3 and the boundary between the sheet S3 and the sheet S2, the control unit 150 ends this processing. Further, when the stop sequence (step ST20) is executed before step ST65, the discharge control is stopped in the stop sequence.

Here, the sheet manufacturing apparatus 100 may be configured to supply the mixed sheet or the sheet S3 from the supply unit 10. Specifically, the control unit 150 includes a mechanism for returning the sheet S from the discharge tray 902 containing the mixed sheets or the discharge tray 902 containing the sheet S3 to the supply unit 10 or the crushing unit 12. May be. Further, the user may be notified of the discharge tray 902 in which the mixed sheet or the sheet S3 is accommodated by the notification unit 164 or the like.

As described above, the sheet manufacturing apparatus 100 according to the first embodiment includes the manufacturing unit 102 that manufactures the sheet S, the operation detection unit 153 that receives the input of the type of the sheet S manufactured by the manufacturing unit 102, and the operation screen 160. With. The sheet manufacturing apparatus 100 includes a control unit 150 that sets operating conditions of the manufacturing unit 102 according to the type of the sheet S based on the input received by the operation detection unit 153 and causes the manufacturing unit 102 to manufacture the sheet S. When the operation detection unit 153 receives a new input of the type of the sheet S while the manufacturing unit 102 manufactures the sheet S, the control unit 150 changes the operating condition of the manufacturing unit 102. Here, the control unit 150 changes the operation condition according to the type of the sheet S based on the new input received by the operation detection unit 153 and continues manufacturing the sheet S.

According to the sheet manufacturing apparatus 100 of the present invention and the sheet manufacturing apparatus 100 to which the control method of the sheet manufacturing apparatus 100 is applied, a new input of the type of the sheet S is received while the sheet S is manufactured, and the sheet The operating conditions for manufacturing S can be changed and the manufacturing of the sheet S can be continued. For this reason, the type of the sheet S to be manufactured can be quickly changed without stopping the operation for manufacturing the sheet S.

The manufacturing unit 102 includes a heating unit 84 that heats a material including fibers and a binder. The control unit 150 sets the temperature of the heating unit 84 as an operation condition of the manufacturing unit 102 according to the type of the sheet S based on the input received by the operation detection unit 153. Thereby, in the apparatus which manufactures the sheet | seat S by heating a material, the temperature which heats in the state which manufactures the sheet | seat S can be changed. For this reason, it is possible to change the type of the sheet S accompanying the change of the heating temperature without stopping the operation of manufacturing the sheet S.

The manufacturing unit 102 includes a plurality of stackers 11 that contain raw materials including fibers for each type, and a supply unit 10 that supplies the raw materials from the stacker 11. The control unit 150 sets the type of raw material supplied from the supply unit 10 as the operating condition of the manufacturing unit 102 according to the type of the sheet S based on the input received by the operation detection unit 153, and according to the set type of raw material The temperature of the heating unit 84 is set. Thereby, in the state which manufactures the sheet | seat S, the raw material used for manufacture of the sheet | seat S can be changed. For this reason, it is possible to change the type of the sheet S accompanying the change of the raw material without stopping the operation of manufacturing the sheet S.

The manufacturing unit 102 includes a plurality of additive cartridges 501 each containing different types of binders. The control unit 150 sets one or more additive cartridges 501 to be used as the operating condition of the manufacturing unit 102 according to the type of the sheet S based on the input received by the operation detection unit 153. The control unit 150 acquires temperature data from the set additive cartridge 501 and sets the temperature of the heating unit 84 based on the acquired temperature data. Thereby, in the apparatus which manufactures sheet | seat S using the additive (binding material) according to the kind of sheet | seat S to manufacture, an additive is changed in the state which manufactures the sheet | seat S, and it is changed to the changed additive. The temperature at which the heating is performed can be changed. For this reason, it becomes possible to change the type of the sheet S accompanied by the change of the additive without stopping the operation of manufacturing the sheet S, and even when the additive is changed, the heating can be appropriately performed. High-quality sheet S can be manufactured.

The control unit 150 can set a plurality of additive cartridges 501 as operating conditions of the manufacturing unit 102. When the temperature data is acquired from each of the set plurality of additive cartridges 501, the control unit 150 sets the temperature of the heating unit 84 based on the temperature data indicating the highest temperature among the acquired temperature data. Thereby, when manufacturing the sheet | seat S using a some additive, an additive can be heated at appropriate temperature and the high quality sheet | seat S can be manufactured.

The control unit 150 sets the operating condition of the manufacturing unit 102 according to the first type of the sheet S based on the input received by the operation detection unit 153. The control unit 150 changes the operating condition of the manufacturing unit 102 according to the second type of the sheet S based on the new input received by the operation detection unit 153 while the sheet S is manufactured by the manufacturing unit 102. . When the manufacture of the sheet S is continued based on the changed operation condition, the control unit 150 includes the first type (sheet S1) and the second type (sheet S2) among the sheets S manufactured by the manufacturing unit 102. Different sheets S (sheets S3) are distinguished. In other words, the intermediate sheet S during the transition from the first type of sheet S to the second type of sheet S can be identified. Thereby, when the operating condition for manufacturing the sheet S is changed, the sheet S different from the type corresponding to the input can be distinguished. For this reason, for example, a sheet S having a desired quality can be easily obtained by distinguishing a sheet S having a property different from the designated sheet S, such as a sheet S manufactured between the start of the change and the completion of the change. Can be taken out.

The manufacturing unit 102 can execute a transport operation for transporting a material related to the manufacture of the sheet S. The control unit 150 sets the operation condition of the manufacturing unit 102 according to the first type of the sheet S based on the input received by the operation detection unit 153, and then receives the operation detection unit 153 during the carrying operation. The input is a new input. Thereby, during the execution of the conveying operation for conveying the material related to the manufacture of the sheet S, the operation condition can be changed according to the input.

The control unit 150 includes at least one of the material for manufacturing the sheet S and the processing conditions for processing the sheet S according to the type of the sheet S based on the input received by the operation detection unit 153. Set such conditions. Thereby, according to the input, conditions including at least one of the material for manufacturing the sheet S and the processing conditions for processing the sheet S can be set, and the conditions can be changed while the operation for manufacturing the sheet S is continued.

[Second Embodiment]
FIG. 16 is a schematic diagram showing a configuration of a sheet manufacturing apparatus 101 according to the second embodiment to which the present invention is applied. FIG. 17 is a flowchart illustrating the operation of the sheet manufacturing apparatus according to the second embodiment.

The sheet manufacturing apparatus 101 includes a winding unit 98 instead of the cutting unit 90 and the discharge unit 97. Except for this difference, since it has the same configuration as the sheet manufacturing apparatus 100 described in the first embodiment, the same configuration is denoted by the same reference numeral and description thereof is omitted.

The manufacturing unit 102a (sheet manufacturing unit) included in the sheet manufacturing apparatus 101 does not include the cutting unit 90. Accordingly, the sheet S pressed and heated by the sheet forming unit 80 is discharged from the manufacturing unit 102a without being cut. The sheet manufacturing apparatus 101 includes a winding unit 98 that winds the uncut sheet S.

The winding unit 98 includes a winding roll 911 that winds up the sheet S, and

tension rollers

912, 913, and 914 that remove slack of the sheet S between the winding roll 911 and the sheet forming unit 80. The

tension rollers

912 and 914 are rotatably installed in the conveyance path of the sheet S, and the tension roller 913 is disposed between the

tension rollers

912 and 914 so as to apply a predetermined tension to the sheet S. The tension roller 913 is relatively movable with respect to the

tension rollers

912 and 914, and is improperly applied by an urging means such as a spring to apply tension to the sheet S.

Further, a marking unit 99 is disposed between the sheet forming unit 80 and the

tension rollers

912, 913, and 914.

The marking unit 99 adds marks (images, symbols, characters, etc.) to predetermined positions on the front or back surface of the sheet S by means such as ink or embossing. Specifically, it includes an adding portion (not shown) that adds a mark by contacting the sheet S, and an actuator or the like (not shown) that presses the adding portion against the sheet S. For example, the marking unit 99 attaches a mark that can be identified by visible light using ink. Or the marking part 99 may add a mark with the material which does not distinguish with visible light but emits fluorescence, when ultraviolet light is irradiated. In the direction orthogonal to the conveyance direction F of the sheet S, the position where the marking unit 99 adds a mark is arbitrary, and can be, for example, an end position, which is a position cut off by the cutting unit 90 (FIG. 1). May be.

The marking unit 99 is connected to the control device 110 by the drive unit I / F 115 (FIG. 4), operates under the control of the control unit 150, and adds a mark at a timing designated by the control unit 150.

Further, the take-up roll 911 is driven by a take-up motor (not shown) and rotates to take up the sheet S. The take-up motor is connected to the control device 110 by a drive unit I / F 115 (FIG. 4) and rotates under the control of the control unit 150. The winding roll 911 is rotated by a winding motor when the manufacturing unit 102a manufactures the sheet S and conveys the raw material.

The operation of the sheet manufacturing apparatus 101 of the second embodiment is the same as the operation of the sheet manufacturing apparatus 100 described above, but is different in the discharge control described with reference to FIG. 15, and will be described with reference to FIG.

In the discharge control shown in FIG. 17, the control unit 150 executes the same processing as in step ST 61 and step ST 62 in FIG. 15.

The control unit 150 determines the timing at which the boundary specified in step ST62 passes the marking unit 99 (step ST81). The control unit 150 controls the actuator and the like of the marking unit 99 to add a mark at the timing specified in step ST62. Thus, in the sheet S, marks are added by the marking unit 99 to the boundary between the sheet S1 and the sheet S3 and the boundary between the sheet S3 and the sheet S2. After the necessary marks are added, the control unit 150 ends the discharge control.
