[First Embodiment]
1. 1. Overall Configuration FIG. 1 is a schematic diagram showing the configuration of the sheet manufacturing apparatus 100 according to the first embodiment to which the present invention is applied.
The sheet manufacturing apparatus 100 according to the present embodiment dry-deflate used used paper such as confidential paper as a raw material to form fibers, and then pressurizes, heats, and cuts the new paper. It is a device suitable for manufacturing. By mixing various additives with the fibrous raw material, it is possible to improve the bond strength and whiteness of paper products and add functions such as color, scent, and flame retardancy according to the application. May be good. In addition, by controlling the density, thickness, and shape of the paper, we can manufacture paper of various thicknesses and sizes according to the application, such as standard size office paper such as A4 and A3, and business card paper. be able to.

The seat manufacturing apparatus 100 includes a manufacturing unit 102 (seat manufacturing unit) and a control device 110. The manufacturing unit 102 manufactures the sheet. The manufacturing unit 102 includes a supply unit 10, a coarse crushing unit 12, a defibration 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 transport unit. A portion 79, a sheet forming portion 80, and a cutting portion 90 are provided.

Further, the sheet manufacturing apparatus 100 includes humidifying portions 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. The specific configurations of the humidifying portions 202, 204, 206, 208, 210, and 212 are arbitrary, and examples thereof include a steam type, a vaporization type, a warm air vaporization type, and an ultrasonic type.

In the present embodiment, the humidifying portions 202, 204, 206, and 208 are composed of a vaporization type or warm air vaporization type humidifier. That is, the humidifying portions 202, 204, 206, and 208 have a filter (not shown) for moistening water, and by passing air through the filter, humidified air with increased humidity is supplied. Further, the humidifying portions 202, 204, 206 and 208 may be provided with heaters (not shown) that effectively increase the humidity of the humidified air.

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

The supply unit 10 supplies the raw material to the coarse crushing unit 12. The raw material for producing the sheet by the sheet manufacturing apparatus 100 may be any material containing fibers, and examples thereof include paper, pulp, pulp sheet, cloth containing non-woven fabric, and woven fabric. In this embodiment, the configuration in which the sheet manufacturing apparatus 100 uses used paper as a raw material is illustrated.

The supply unit 10 includes, for example, a plurality of stackers 11 (accommodation units) for accommodating used paper (raw materials). Recycled paper is piled up and accumulated in each stacker 11. 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 loading device that selects one of a plurality of stackers 11 and sends the used paper from the selected stacker 11 to the coarse crushing unit 12. The stacker 11 selected by the supply unit 10 is designated by the control of the control device 110.

The crushing unit 12 cuts (coarsely) the raw material supplied by the supply unit 10 with the crushing blade 14 to make coarse crushed pieces. The coarse crushing blade 14 cuts the raw material in the air (in the air) or the like. The rough crushing portion 12 includes, for example, a pair of rough crushing blades 14 for cutting by sandwiching a raw material and a driving portion for rotating the rough crushing blade 14, and can have the same configuration as a so-called shredder. The shape and size of the coarsely crushed pieces are arbitrary, and may be suitable for the defibration treatment in the defibration portion 20. For example, the coarsely crushed portion 12 cuts the raw material into pieces of paper having a size of 1 to several cm square or less.

The crushed portion 12 has a chute (hopper) 9 that receives the crushed pieces that are cut by the crushing blade 14 and fall. The chute 9 has, for example, a tapered shape in which the width gradually narrows in the direction in which the coarse crushed pieces flow (the direction in which the coarse crushed pieces travel). Therefore, the chute 9 can receive a large number of coarse fragments. A pipe 2 communicating with the defibration portion 20 is connected to the chute 9, and the pipe 2 forms a transport path for transporting the raw material (coarse crushed piece) cut by the coarse crushing blade 14 to the defibration portion 20. .. The coarsely crushed pieces are collected by the chute 9 and transferred (transported) to the defibration section 20 through the tube 2.

Humidified air is supplied by the humidifying unit 202 to the chute 9 or the vicinity of the chute 9 included in the coarsely crushed unit 12. As a result, it is possible to suppress the phenomenon that the coarsely crushed material cut by the coarsely crushed blade 14 is adsorbed on the inner surface of the chute 9 or the pipe 2 by static electricity. Further, since the coarsely crushed material cut by the coarsely crushed blade 14 is transferred to the defibration portion 20 together with the humidified (high humidity) air, it also has the effect of suppressing the adhesion of the defibrated material inside the defibration portion 20. You can expect it. Further, the humidifying unit 202 may be configured to supply humidified air to the coarse crushing blade 14 to eliminate static electricity from the raw material supplied by the supply unit 10. Further, static electricity may be removed by using an ionizer together with the humidifying unit 202.

The defibration section 20 defibrate the coarsely crushed product cut by the coarse crushing section 12. More specifically, the defibration section 20 defibrate the raw material (coarse crushed piece) cut by the coarse crushing section 12 to produce a defibrated product. Here, "defibrating" means unraveling a raw material (defibrated material) formed by binding a plurality of fibers into individual fibers. The defibration unit 20 also has a function of separating substances such as resin particles, ink, toner, and bleeding inhibitor adhering to the raw material from the fibers.

A product that has passed through the defibration section 20 is called a "defibration product". "Fibers" include, in addition to the unraveled defibrated fibers, resin grains (resin for binding multiple fibers) separated from the fibers when the fibers are unraveled, ink, toner, etc. It may also contain additives such as a colorant, an anti-bleeding agent, and a paper strength enhancer. The shape of the unraveled defibrated product is a string shape or a ribbon shape. The unraveled defibrated product may exist in an unentangled state (independent state) with other unraveled fibers, or may be entangled with other unraveled defibrated products to form a lump. It may exist in a state (a state forming a so-called "dama").

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

In this way, the defibrated product produced by the defibrating section 20 is conveyed from the defibrating section 20 to the sorting section 40 by the air flow generated by the defibrating section 20. Further, in the present embodiment, the sheet manufacturing apparatus 100 includes a defibration section blower 26 which is an air flow generator, and the defibrated product is conveyed to the sorting section 40 by the air flow generated by the defibration section blower 26. The defibration section blower 26 is attached to the tube 3, sucks air from the defibration section 20 together with the defibrated material, and blows air to the sorting section 40.

The sorting unit 40 has an introduction port 42 through which the defibrated product defibrated by the defibrating unit 20 flows from the tube 3 together with the air flow. The sorting unit 40 sorts the defibrated products to be introduced into the introduction port 42 according to the length of the fibers. Specifically, among the defibrated products defibrated by the defibrating unit 20, the sorting unit 40 uses a defibrated product having a predetermined size or less as the first defibrated product, and is larger than the first defibrated product. Is selected as the second selection product. The first sort contains fibers, particles, etc., and the second sort includes, for example, large fibers, undefibrated pieces (coarse crushed pieces that are not sufficiently defibrated), and defibrated fibers that are aggregated or entangled. Including lumps and the like.

In the present embodiment, the sorting unit 40 has a drum unit 41 (sieving unit) and a housing unit (covering unit) 43 for accommodating 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 (sieve). According to the mesh, the drum portion 41 sorts the first selection smaller than the size of the mesh opening (opening) and the second selection larger than the mesh opening (opening) of the mesh. As the net of the drum portion 41, for example, a wire mesh, an expanded metal obtained by stretching a metal plate having a cut, 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 product introduced into the introduction port 42 is sent into the inside of the drum portion 41 together with the air flow, and the first sorted product falls downward from the mesh of the drum portion 41 due to the rotation of the drum portion 41. The second sorting material that cannot pass through the mesh of the drum portion 41 is flowed by the air flow flowing into the drum portion 41 from the introduction port 42, guided to the discharge port 44, and sent out to the pipe 8.
The pipe 8 connects the inside of the drum portion 41 and the pipe 2. The second sort product flowing through the pipe 8 flows through the pipe 2 together with the coarsely crushed pieces cut by the coarse crushing portion 12, and is guided to the introduction port 22 of the defibrating portion 20. As a result, the second sorted product is returned to the defibration section 20 and defibrated.

Further, the first sorted product sorted by the drum portion 41 is dispersed in the air through the mesh of the drum portion 41 and is attached to the mesh belt 46 of the first web forming portion 45 located below the drum portion 41. Descent towards.

The first web forming portion 45 (separation portion) includes a mesh belt 46 (separation belt), a roller 47, and a suction portion (suction mechanism) 48. The mesh belt 46 is an endless belt, which 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 composed of a net in which openings of a predetermined size are lined up. Of the first sorted material that descends from the sorting unit 40, fine particles of a size that passes through the mesh fall below the mesh belt 46, and fibers of a size that cannot pass through the mesh are deposited on the mesh belt 46 to form a mesh. It is conveyed in the direction of arrow V1 together with the belt 46. The fine particles falling from the mesh belt 46 include relatively small defibrated products and low densities (resin particles, coloring agents, additives, etc.), and are not used by the sheet manufacturing apparatus 100 for manufacturing the sheet S. It is a remover.

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

Here, the operation operation is an operation other than the execution of the start control and the stop control of the seat manufacturing apparatus 100, which will be described later, and more specifically, the seat manufacturing apparatus 100 manufactures the seat S having a desirable quality. Point while doing.
Therefore, the defibrated product that has been defibrated by the defibrating unit 20 is sorted into a first sorted product and a second sorted product by the sorting unit 40, and the second sorted product is returned to the defibrating unit 20. In addition, the removed product is removed from the first sorted product by the first web forming unit 45. The remainder after removing the removed material from the first sort is a material suitable for producing 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 collector) via the pipe 23. The dust collector 27 separates the fine particles from the air flow. 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 to the outside of the sheet manufacturing apparatus 100 through the pipe 29.

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

Therefore, the fibers from which the removed material has been removed from the first selected material are deposited on the mesh belt 46 to form the first web W1. The suction by the collection blower 28 promotes the formation of the first web W1 on the mesh belt 46, and the removed material is quickly removed.

Humidified air is supplied to the space including the drum portion 41 by the humidifying portion 204. The first sorted product is humidified inside the sorting unit 40 by this humidified air. As a result, the adhesion of the first sorted product to the mesh belt 46 due to the electrostatic force can be weakened, and the first sorted product can be easily peeled off from the mesh belt 46. Further, it is possible to prevent the first sorted object from adhering to the inner wall of the rotating body 49 or the housing portion 43 due to the electrostatic force. In addition, the suction unit 48 can efficiently suck the removed material.

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

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

The sheet manufacturing apparatus 100 includes a rotating body 49 that divides the first web W1 deposited on the mesh belt 46. The first web W1 is separated from the mesh belt 46 at a position where the mesh belt 46 is folded back by the roller 47, and is separated by the rotating body 49.

The first web W1 is a soft material in which fibers are deposited to form a web shape, and the rotating body 49 loosens the fibers of the first web W1 and processes the resin in a mixing portion 50 so that the resin can be easily mixed.

The configuration of the rotating body 49 is arbitrary, but in the present embodiment, it can have a rotating blade shape having plate-shaped blades and rotating. The rotating body 49 is arranged at a position where the first web W1 peeling from the mesh belt 46 and the blade come into contact with each other. Due to the rotation of the rotating body 49 (for example, the rotation in the direction indicated by the arrow R in the drawing), the blades collide with the first web W1 that is separated from the mesh belt 46 and conveyed, and the blades collide with each other to divide the rotating body 49, 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 does not damage the mesh belt 46. 1 Web W1 can be divided efficiently.

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

The mixing unit 50 includes an additive supply unit 52 that supplies an additive containing a resin, a pipe 54 that communicates with the pipe 7 and allows an air flow containing the subdivision P, and a mixing blower 56. The subdivision 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 subdivision P. The additive acts, for example, as a binder that binds the fibers together.
In the mixing unit 50, an air flow is generated by the mixing blower 56, and the subdivision P and the additive are mixed and conveyed in the pipe 54. Further, the subdivision P is loosened in the process of flowing inside the pipe 7 and the pipe 54 to become a finer fibrous form.

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 inside the additive cartridge 501 to the pipe 54. The additive cartridge 501 mounted on the additive supply unit 52 may be provided with a configuration for replenishing 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 contains 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 admixture. That is, the additive may contain a single substance, may be a mixture, and may contain a plurality of types of particles each composed of a single substance or a plurality of substances. Further, the additive may be in the form of fibers or in the form of powder.

The resin contained in the additive melts by heating and binds a plurality of fibers to each other. Therefore, 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.
The additives supplied by the additive supply unit 52 include a resin for binding the fibers, a colorant for coloring the fibers depending on the type of the sheet to be manufactured, and agglomeration of the fibers and agglomeration of the resin. It may contain a coagulation inhibitor for suppressing the amount of heat, and a flame retardant for making fibers and the like hard to burn. In addition, the additive that does not contain a colorant may be colorless, or may be light in color so that it can be regarded as colorless, or may be white.

Due to the air flow generated by the mixing blower 56, the subdivision P descending the pipe 7 and the additive supplied by the additive supply unit 52 are sucked into the inside of the pipe 54 and pass through the inside of the mixing blower 56. The airflow generated by the mixed blower 56 and / or the action of rotating parts such as blades of the mixed blower 56 mix the fibers constituting the subdivision P and the additive, and this mixture (first selection and addition). The mixture with the material) is transferred to the deposit 60 through the pipe 54.

The mechanism for mixing the first sorted product and the additive is not particularly limited, and may be agitated by blades rotating at high speed, or may use the rotation of the container like a V-type mixer. These mechanisms may be installed before or after the mixing blower 56.

The depositing portion 60 deposits the defibrated product defibrated by the defibrating portion 20. More specifically, the depositing portion 60 introduces the mixture that has passed through the mixing portion 50 from the introduction port 62, loosens the entangled defibrated products (fibers), and causes the mixture to fall while being dispersed in the air. Further, when the resin of the additive supplied from the additive supply unit 52 is fibrous, the deposition unit 60 loosens the entangled resin. As a result, the depositing portion 60 can uniformly deposit the mixture on the second web forming portion 70.

The stacking portion 60 has a drum portion 61 and a housing portion (covering portion) 63 for accommodating the drum portion 61. The drum portion 61 is a cylindrical sieve that is rotationally driven by a motor. The drum portion 61 has a net (filter, screen) and functions as a sieve (sieve). Through this mesh, the drum portion 61 allows fibers and particles having a smaller mesh opening (opening) to pass through and is lowered from the drum portion 61. The configuration of the drum portion 61 is, for example, the same as the configuration of the drum portion 41.

The "sieve" of the drum portion 61 may not have a function of selecting a specific object. That is, the "sieve" used as the drum portion 61 means that the drum portion 61 is provided with a net, and the drum portion 61 may drop all of the mixture introduced into the drum portion 61.

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

The mesh belt 72 is an endless belt, is suspended by a plurality of rollers 74, and is conveyed in the direction indicated by the arrow V2 in the drawing by the movement of the rollers 74. The mesh belt 72 is made of, for example, metal, resin, cloth, non-woven fabric, or the like. The surface of the mesh belt 72 is composed of a net in which openings of a predetermined size are lined up. Of the fibers and particles falling from the drum portion 61, fine particles of a size that passes through the mesh fall below the mesh belt 72, and fibers of a size that cannot pass through the mesh are deposited on the mesh belt 72, and the mesh belt It is conveyed in the direction of the arrow together with 72. The mesh belt 72 moves at a constant speed V2 during the operation for manufacturing the seat S. The driving operation is as described above.

The moving speed V2 of the mesh belt 72 can be regarded as the speed at which the second web W2 is conveyed, and the speed V2 can be said to be the conveying speed of the second web W2 on 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 falling from the drum portion 61 do not pass through.
The suction mechanism 76 is provided below the mesh belt 72 (on the side opposite to the deposition portion 60 side). The suction mechanism 76 includes a suction blower 77, and the suction force of the suction blower 77 can generate a downward airflow (airflow from the deposit portion 60 toward the mesh belt 72) in the suction mechanism 76.

The suction mechanism 76 sucks the mixture dispersed in the air by the deposit 60 onto the mesh belt 72. As a result, the formation of the second web W2 on the mesh belt 72 can be promoted, and the discharge rate from the deposition portion 60 can be increased. Further, the suction mechanism 76 can form a downflow in the fall path of the mixture, and can prevent the defibrated products and additives from being entangled during the fall.
The suction blower 77 (deposition suction unit) may discharge the air sucked from the suction mechanism 76 to the outside of the sheet manufacturing apparatus 100 through a collection filter (not shown). Alternatively, the air sucked by the suction blower 77 may be sent to the dust collecting unit 27 to collect the removed material contained in the air sucked by the suction mechanism 76.

Humidified air is supplied to the space including the drum portion 61 by the humidifying portion 208. The inside of the deposition portion 60 can be humidified by this humidified air, the adhesion of fibers and particles to the housing portion 63 due to electrostatic force is suppressed, and the fibers and particles are quickly dropped onto the mesh belt 72, and the shape of the first is preferable. 2 Web W2 can be formed.

As described above, the second web W2 in a soft and swollen state containing a large amount of air is formed by passing through the deposition portion 60 and the second web forming portion 70 (web forming step). The second web W2 deposited on the mesh belt 72 is conveyed to the sheet forming portion 80.

In the transport path of the mesh belt 72, air containing mist is supplied to the downstream side of the depositing portion 60 by the humidifying portion 212. As a result, the mist generated by the humidifying portion 212 is supplied to the second web W2, and the amount of water contained in the second web W2 is adjusted. As a result, it is possible to suppress the adsorption of fibers to the mesh belt 72 due to static electricity.

The suction mechanism 79c includes an intermediate blower 318 (FIG. 3), and the suction force of the intermediate blower 318 generates an upward air flow in the mesh belt 79a. This air flow sucks the second web W2, and the second web W2 is separated from the mesh belt 72 and attracted to 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 portion 80.
In this way, the transport unit 79 peels off the second web W2 formed on the mesh belt 72 from the mesh belt 72 and transports the second web W2.

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) who operates the seat manufacturing apparatus 100 to perform the operation.

The operation screen 160 of FIG. 5 is displayed by the display panel 116 after the power of the seat manufacturing apparatus 100 is turned on, and continues while the seat manufacturing apparatus 100 manufactures the seat S or in the standby state described later. It may be displayed.

An operation instruction unit 161, a cartridge information display unit 162, a seat setting unit 163, and a notification unit 164 are arranged on the operation screen 160. The operation instruction unit 161 and the seat setting unit 163 form a GUI for the 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, a stop instruction button 161b, an interruption instruction button 161c, and a standby instruction button 161d that function as buttons (operation units) for instructing the operation of the seat manufacturing apparatus 100.

The sheet setting unit 163 has 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 the conditions of the sheet S manufactured by the sheet manufacturing apparatus 100.

Each operation unit arranged in the operation instruction unit 161 and the seat setting unit 163 may be installed in the housing of the seat manufacturing apparatus 100 as a physical button. In this embodiment, as an example, an example in which each of the above operation units is provided as a GUI (icon) by the display panel 116 and the touch sensor 117 will be described.

The color setting unit 163a is an operation unit for designating the color of the sheet S. In the example of FIG. 5, the user operates the color setting unit 163a to select the color of the sheet S from a plurality of preset colors by the 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 of the additive cartridge 501 mounted on the additive supply unit 52 according to the selected color. Determine the proportion of each additive when The drive control unit 156 determines the amount of the additive supplied from each additive cartridge 501 based on the type of the additive 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 and the thickness of a plurality of preset steps can be selected from the pull-down menu. The control unit 150 acquires the thickness selected by the operation of the thickness setting unit 163b by the operation detection unit 153. The drive control unit 156 determines the thickness of the second web W2 to be deposited on the mesh belt 72 in the deposition unit 60 and / or the load applied to the second web W2 by the pressurizing unit 82 according to the selected thickness. Determine the conditions of. 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 operating conditions of the pressurizing unit drive motor 335, and the like in accordance with the determined conditions.

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

Further, in the sheet setting unit 163, in addition to the above-mentioned buttons, a button for specifying the number of sheets S to be manufactured and a button for specifying the size (size) of the sheet S may be arranged, and other sheets may be arranged. A button for designating the condition relating to S may be arranged.

The start instruction button 161a is a button for instructing the start of manufacturing of the sheet S. The start instruction button 161a is operated, for example, after the conditions related to the seat S are specified by the operation of the seat setting unit 163, and instructs the start of production of the seat S based on the specified conditions. If the seat setting unit 163 is provided with a default specified value in advance and the start instruction button 161a is operated while the seat 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 the stop of the operation of the sheet manufacturing apparatus 100. In addition to the display panel 116, the housing of the sheet manufacturing apparatus 100 may be provided with a power switch (not shown) for turning on / off the power of the seat manufacturing apparatus 100. In this case, the stop instruction button 161b functions as a button for instructing the stop of the seat manufacturing apparatus 100, but the stop instruction button 161b may be configured to instruct the power off of the seat manufacturing apparatus 100. When the sheet manufacturing apparatus 100 stops manufacturing the seat S by operating the stop instruction button 161b, the condition related to the seat S set by the seat setting unit 163 is cleared, and the default designated value (initial value) is restored.

The interrupt instruction button 161c temporarily stops the production of the sheet S while the sheet production apparatus 100 is executing the production of the sheet S. When the interruption instruction button 161c is operated and the sheet manufacturing apparatus 100 stops manufacturing the seat S, the conditions related to the seat S set by the seat setting unit 163 are retained. When the start instruction button 161a is operated in this state, the control unit 150 starts (restarts) the production of the seat S according to the same conditions as before the interruption instruction button 161c is operated by the sheet production apparatus 100.

The standby instruction button 161d is a button for instructing the transition to the standby state, which will 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 called a "job". The job refers to the operation of the sheet setting unit 163 or the operation of manufacturing the sheet S under the conditions specified by the default value. Specifically, from the start of the operation in response to the operation of the start instruction button 161a until the production of the number of sheets S specified by the operation of the sheet setting unit 163 is completed, or the operation of the stop instruction button 161b. The operation until it is stopped by is called a job. When the number of sheets S to be manufactured is specified, the end of the job is clearly specified. If the stop instruction button 161b is operated without specifying the number of sheets S, or if the stop instruction button 161b is operated before the production of the specified number of sheets S is completed, there is no prior setting. , The job ends. When the interruption instruction button 161c is operated, the sheet manufacturing apparatus 100 interrupts the job, but does not end the job. Therefore, when the start instruction button 161a is operated after the production of the sheet S is stopped in response to the operation of the interruption instruction button 161c, the sheet production apparatus 100 resumes the production 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 if the start instruction button 161a is operated thereafter, the job continues.

The cartridge information display unit 162 is a display unit that displays information about the additive cartridge 501 mounted (set) on the additive supply unit 52. The cartridge information display unit 162 displays an image imitating the additive cartridge 501, corresponding to the number of additive cartridges 501 that can be mounted on 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 by text or an image corresponding to the image of each additive cartridge 501. .. When the number of additive cartridges 501 mounted on the additive supply unit 52 is less than the number that can be mounted, the image corresponding to the additive cartridge 501 that is not mounted is displayed blank.

The notification unit 164 is a display area in which the content to be notified to the user is displayed by 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 in particular, 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, the temperature data "Th11" is acquired from IC521 of the yellow (YELLOW in the figure) additive cartridge 501. Further, "Th12" is acquired from IC521 of the additive cartridge 501 of Magenta, and "Th13" is acquired from IC521 of the additive cartridge 501 of cyan (CYAN). Further, "Th14" is acquired from IC521 of the white (WHITE) additive cartridge 501, and "Th15" is acquired from IC521 of the plain (PLAY) additive cartridge 501. Th11, Th12, Th13, Th14, and Th15 are numerical values or codes indicating specific temperatures or temperature ranges, respectively. These temperatures are set so that the resin contained in each additive is melted in an appropriate state in the heating unit 84, the fibers are adhered with a preferable strength, and good color development is obtained. When manufacturing the sheet S, the control unit 150 specifies the additive to be used for manufacturing the sheet S, and then the control unit 150 heats the sheet S based on the temperature data read from the IC 521 of the additive cartridge 501 containing the specified additive. The heating temperature of 84 is set. As a result, the second web W2 can be heated at an appropriate temperature in the heating unit 84, and a high-quality sheet S can be produced. The specific temperature of Th11 to Th15 differs depending on the specific properties of the additive, but it is higher than the so-called room temperature because the additive is rarely melted at a temperature close to room temperature. For example, it is not uncommon for temperatures to exceed 100 degrees Celsius.

The drive control unit 156 of the control unit 150 (FIG. 4) uses the additives among the additive cartridges 501 mounted on the additive supply unit 52 based on the contents input on the operation screen 160 (FIG. 5). Identify the cartridge 501. Specifically, the type of additive (for example, color) to be used is determined based on the color specified by the operation of the color setting unit 163a of the sheet setting unit 163 and the type of the raw material specified by the operation of the raw material setting unit 163c. Identify and identify the additive cartridge 501 containing the identified type of additive. Further, the drive control unit 156 obtains the amount of the additive supplied from the specified additive cartridge 501 per unit time, and sets the 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 temperature data can be read from the IC 521, for example, when the power of 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 the data from the detected IC 521. Further, when the data acquisition unit 155 detects that the additive cartridge 501 is mounted, 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 the identification information that identifies the IC 521. The identification information of the IC 521 is, for example, an ID unique to the IC 521, 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, under the control of the drive control unit 156, the data acquisition unit 155 may read the temperature data by the IC reading unit 119 at any time.

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

When a plurality of types of additives are selected based on the input of the operation screen 160, the heating control unit 157 acquires the temperature data corresponding to each additive, and determines 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, it is assumed that 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 temperature data Th11 and temperature data Th13, and the heating temperature is based on the temperature data Th13, which is the higher temperature. To determine. In this method, when a plurality of types of additives are used, heating is performed according to the additives that require heating at a higher temperature, so that all the additives are heated to a temperature higher than the required temperature. Therefore, it is possible to prevent the quality of the sheet S from deteriorating due to insufficient heating. Further, the heating control unit 157 may determine the heating temperature based on a plurality of temperature data, reflecting the ratio of the amount of the plurality of types of additives used.

By the way, the seat manufacturing apparatus 100 starts manufacturing the seat S by operating the operation screen 160 by the user, and can receive an input related to the seat S on the operation screen 160 during the operation of manufacturing the seat S. Specifically, after the manufacturing unit 102 starts the job based on the input on the operation screen 160 and before the job is completed, the input on the operation screen 160 can be accepted. The input (new input) received here includes the input regarding the color, thickness, and raw material of the sheet S by the sheet setting unit 163. When the operating conditions of the manufacturing unit 102 related to the manufacturing of the sheet S are changed from the new input during the manufacturing of the sheet S (during the execution of the job), the control unit 150 changes to the conditions 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 operating conditions 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 showing an example of an operating state of the sheet manufacturing apparatus 100.
In the figure, the supply unit refers to the supply unit 10, for example, the state of the paper feed motor 315. The crushed portion refers to the crushed portion 12, for example, the state of the crushed portion drive motor 311. The defibration section refers to the defibration section 20, specifically, the state of the defibration section drive motor 313, but the defibration section 20 may be in an operating state including the state of the defibration section blower 26. The sorting unit refers to the sorting unit 40, specifically, the state of the drum drive motor. The first web forming unit refers to the first web forming unit 45, and specifically refers to the state of the belt drive motor 327, but the operating state of the first web forming unit 45 may be included including the state of the collection blower 28. The rotating body refers to the rotating state of the dividing portion drive motor 329 that drives the rotating body 49.

The mixing unit refers to the state of the mixing unit 50, specifically, the operating state of the additive supply motor 317 and the mixing blower 56 that drive the additive supply unit 52. The depositing portion refers to the depositing portion 60, and specifically refers to the operating state of the drum drive motor 331 that moves the drum portion 61. The second web forming portion refers to the second web forming portion 70, specifically, the operating state of the belt drive motor 333, but may be the operating state of the second web forming portion 70 including the suction blower 77. The pressurizing unit refers to the pressurizing unit 82, specifically, the operating state of the pressurizing unit drive motor 335, but may include a load state 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. Further, the cutting portion refers to the cutting portion 90, specifically, the operating state of the cutting portion drive motor 351. However, the cutting portion 90 may include the operating state of the transport unit (not shown) that conveys the sheet S. The discharge unit refers to an operating state of a transport unit (not shown) that transports the sheet S to the discharge unit 97. The humidifying heater refers to the state of the humidifying heater 345.

Further, FIG. 7 shows a state of control in which the control unit 150 drives each unit without being limited to the energized state of each drive unit. For example, ON / OFF for heating of the heating unit 84 does not indicate ON / OFF of energization of the heater 339, but indicates whether or not the control unit 150 controls for heating by the heater 339. Therefore, even if there is a moment when the heater 339 is not actually energized, the operating state is ON while the control unit 150 controls for heating by the heater 339. The same applies to other drive units.

In FIG. 7, the state in which the manufacturing unit 102 manufactures the sheet S at the heating temperature T1 is shown as “during continuous operation (temperature T1)”, and the state in which the sheet S is manufactured at the heating temperature T2 is “during continuous operation (temperature)”. It is shown as "T2)". Further, the operating state during the change of the heating temperature from the temperature T1 to the temperature T2 is shown as "at the time of temperature change".
As shown in FIG. 7, each drive unit of the manufacturing unit 102 is maintained ON not only during “continuous operation (temperature T1)” and “continuous operation (temperature T2)” but also during “temperature change”. NS. The manufacturing unit 102 supplies additives to the raw material supplied by the supply unit 10, the defibrated product defibrated by the defibration unit 20, the first web W1, the subdivision P, and the subdivision P when the temperature is changed. In part 52, the mixture containing the additives, the second web W2, and the sheet S are continuously conveyed. Further, the manufacturing unit 102 continuously executes the processing for these even when the temperature is changed.

FIG. 8 is a timing chart showing an operation example of the sheet manufacturing apparatus 100, and in particular, shows a change in the temperature of the heating roller 86. The vertical axis of FIG. 8 shows the temperature of the heating roller 86. This temperature is, for example, the temperature detected by the temperature sensor 309. 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, the temperature pattern G shows a temperature change when the heating temperature is changed from T1 to a temperature T2 higher than the temperature T1 under the control of the heating control unit 157. The time t1 is a timing at which the condition input by the operation of the seat setting unit 163 is determined, and is, for example, a timing at which the start instruction button 161a is operated after the operation of the seat setting unit 163. The time t2 is the timing at which the heating temperature, that is, the temperature of the heating roller 86 reaches the temperature T2. That is, the period TE1 from the time t1 to the 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 the period TE1 is heated at a temperature lower than the set temperature. .. Therefore, the sheet S that has passed through the heating unit 84 during the period TE1 may have properties different from those of the set type of sheet S. For example, when the type of additive to be added is changed by the additive supply unit 52 at time t1, the heating temperature T2 suitable for the changed additive is set at time t1. It is desirable that the sheet S containing the modified additive be heated at the temperature T2.

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

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

FIG. 9 is a schematic view 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.
Reference numeral M in the figure indicates a mixture in which the additive is mixed with the subdivision P by the additive supply unit 52. The mixture M, the second web W2, and the sheet S are generically referred to as an object to be transported FM.

FIG. 9 shows a plurality of stages PR1, PR2, PR3, PR4, PR5, PR6, PR7, and PR11 in the manufacturing process of the sheet S. Step PR1 is a step in which the additive is mixed with the subdivision P by the additive supply unit 52. The step PR11 is a step of depositing the mixture M on the mesh belt 72, the step PR2 indicates the start of the step PR11, and the step PR3 indicates the end of the step PR11. The step PR4 is a step in which the pressurizing section 82 pressurizes the second web W2 to form the sheet S, and the step PR5 is a step in which the heating section 84 heats the sheet S. Step PR6 is a step of cutting the sheet S at the first cutting section 92, and step PR7 is a step of cutting the sheet S at the second cutting section 94. Although the deposition process of the mixture M is continuously performed, the completion of the deposition process corresponding to the length of one sheet S is shown as step PR3 in FIG. 9 for convenience of understanding. Further, before the stage PR2, the mixture M is conveyed inside the pipe 54 by the air flow and is not in the shape of a sheet or a web, but is shown in a strip shape in FIG. 9 for convenience of understanding.

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 the step PR1. At this time, between the stages PR1 to PR7, there is an FM to be transported containing the additive before the change. Among the FM to be transported, the sheet S existing between the stages PR5 to the stage PR7 contains the additive before the change and is heated at the heating temperature T1 suitable for the additive before the change. Satisfy the quality of the sheet S of. On the other hand, the material to be transported FM located between the stages PR1 to the stage PR5 contains the material before the 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 either the type of the sheet S before or after the change.

The control unit 150 displays the FM to be transported 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 in the stage after the stage PR5 at this timing, and the sheet S. Distinguish from materials in stages prior to stage PR1. Specifically, the length of the section L1 or the transport 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, in response to the change in the type of the sheet S by the input of the operation screen 160, the type and amount of the additive are changed according to the type of the changed sheet S, and the additive is added after the change. The heating temperature is changed based on the temperature data according to the type of object. Therefore, the type and amount of the additive added by the additive supply unit 52 and the setting of the heating temperature are changed almost at the same time. 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 changes the temperature of the heating roller 86. Requires different times and may not always start or end at the same time. Therefore, the control performed by the control unit 150 with respect to these timings will be described.

10 and 11 are schematic views showing changes in the sheets 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, reference numerals B1, B2, and B3 refer to specific positions on the sheet S. Reference numeral B1 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 numeral 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 before the change (for example, the temperature T1) 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 heating temperature T2.

Focusing on the additive, the position B3 indicates the position on the sheet S containing the material located in the step 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 containing the additive before the change and the sheet S22 containing the additive after the change.

As described above, when the type of the sheet S to be produced is changed, both the type and / or the 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 required: (1) containing the set additive and (2) being heated at the set heating temperature.

As shown in FIG. 10, when the timing at which the temperature of the heating unit 84 changes and the timing at which the additive supply unit 52 switches the additive do not match, the sheet manufacturing apparatus 100 has the above-mentioned (1) and (2). Distinguish between the sheet S that satisfies both conditions and the other sheet 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. Therefore, the seat S before the position B1 is the type of seat S before the change (hereinafter referred to as the seat 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 seat S after the position B2 is the changed type of seat S (hereinafter referred to as the seat S2).
On the other hand, in the sheet S3 between positions B1 and B2, the consistency 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. Therefore, the sheet manufacturing apparatus 100 uses 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 of changing the additive in the additive supply unit 52 is later than the timing of completing the change of the heating temperature of the heating unit 84. In this example, position B3 is located before position B2. Therefore, 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 to B3 is designated as the sheet S2. Distinguished.

By controlling the discharge switching unit 903 of the discharge unit 97, the drive control unit 156 can discharge, for example, the sheets S1, S2, and S3 to different discharge trays 902 and accommodate them. The positions B1, B2, and B3 on the seat S can be specified by the control unit 150 based on the timing at which the control unit 150 controls and the transport speed of the second web W2 and the seat S. Therefore, the drive control unit 156 can specify the sheet S to be discharged before and after the positions B1, B2, and B3 in the discharge unit 97 by controlling the discharge switching unit 903, and can switch the sheet S by the discharge switching unit 903. can.

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

When the power of the seat manufacturing apparatus 100 is turned on (step ST11), the display control unit 152 causes the display panel 116 to display the operation screen 160 (step ST12). The operation detection unit 153 detects an operation on the operation screen 160 by the user, performs a process of accepting 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 contents 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 process executed in step ST14 is shown in detail in FIG.
The control unit 150 specifies the additive cartridge 501 to be used among the additive cartridges 501 mounted on the additive supply unit 52 based on the operation content acquired in step ST13 (step ST31). For example, the type of additive to be used is specified based on the color specified by the operation of the color setting unit 163a of the sheet setting unit 163 and the type of the raw material specified by the operation of the raw material setting unit 163c, and the specified type of additive is specified. The additive cartridge 501 containing the additive is identified. Further, the control unit 150 obtains the amount of the additive per unit time supplied from the specified additive cartridge 501, and sets the conditions for operating the additive supply motor 317.

The control unit 150 acquires the 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, an example of determining the heating temperature based on the temperature data read from the IC 521 of the additive cartridge 501 accommodating the additive to be used has been described, but it 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 unit 150 may set the temperature on the higher side of the highest temperature of the temperature data corresponding to the additive to be used and the heating temperature corresponding to the raw material as the heating temperature.

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

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. Further, the activation sequence includes initialization of the operation of each drive unit connected to the drive unit I / F 115, and control of shifting each drive unit to a state in which the production of the seat S can be started. In this activation sequence, the control unit 150 switches the power supply of the heater 339 to ON and starts the temperature rise. Further, the control unit 150 switches the power supply of the humidifying heater 345 to ON and starts raising the temperature.

The control unit 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 it has not reached the heating temperature (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 seat S, that is, a job. (Step ST17).

After the start of manufacturing the sheet S, the control unit 150 detects an input that causes a change in the operating conditions of the manufacturing unit 102 by operating the operation screen 160 (step ST18).
Specifically, the control unit 150 detects an input for changing the type of the seat S on the operation screen 160. If this input is not provided (step ST18; No), the control unit 150 determines whether or not the job has been completed (step ST19). For example, when the number of sheets S to be manufactured in step ST13 is specified and the production 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 the stop sequence to shift the sheet manufacturing apparatus 100 to the stopped state (step ST20). In the stop sequence, each drive unit of the manufacturing unit 102 is stopped.

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

Further, when the input regarding the type of the sheet S is detected by the operation of the sheet setting unit 163 during the execution of the job (step ST18; Yes), the control unit 150 changes the operating conditions of the manufacturing unit 102. (Step ST21).

The condition change process executed in step ST21 is shown in detail in FIG.
The operation detection unit 153 performs a process of accepting an input by a user's operation and acquires an operation content (step ST41).

The control unit 150 specifies the additive cartridge 501 to be used among the additive cartridges 501 mounted on the additive supply unit 52 based on the operation content acquired by the operation detection unit 153 in step ST41 (step ST42). .. This process is the same as in step ST31. The control unit 150 acquires the 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 in 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 in step ST33. For example, the control unit 150 may determine the heating temperature according to the raw material supplied from the supply unit 10, as described in step ST33.

The control unit 150 changes the setting of the operating conditions of the manufacturing unit 102 based on the type of cartridge specified in step ST42, the amount of additives supplied from each cartridge, and / or the heating temperature determined in step ST44 ( Step ST45).

Here, the control unit 150 determines whether or not the setting related to the material has been 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 the material is changed (step ST46; Yes), the control unit 150 causes the additive supply to be executed by reflecting the changed setting regarding the supply of the additive from the additive supply unit 52 (step). ST47). In step ST47, the change in 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 at which the supply of the additive is changed (step ST48), and proceeds to step ST49. In step ST48, the control unit 150 stores, for example, data indicating the timing of the change in the storage unit 140. Further, for example, the counting of the elapsed time from the change may be started. When it is determined in step ST45 that the setting related to the material has not been changed (step ST46; No), the control unit 150 shifts to step ST49.

In step ST49, the control unit 150 determines whether or not the setting regarding the heating temperature of the heating unit 84 has been changed in step ST45 (step ST49). When the setting regarding 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 unit 150 records the timing at which the temperature change is started (step ST51). In step ST51, the control unit 150 stores, for example, data indicating the timing of the change in the storage unit 140. Further, for example, the counting of the elapsed time from the start of the 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 waits while the temperature does not reach the heating temperature (step ST52; No). 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 ST52; Yes), the control unit 150 records the timing at which the temperature change is completed (step ST53), and returns to FIG. In step ST53, the control unit 150 stores, for example, data indicating the timing of the change in the storage unit 140. Further, for example, the counting of the elapsed time from the end of the change may be started. Further, when it is determined that the setting regarding the heating temperature of the heating unit 84 has not been changed (step ST49; No), the process returns to FIG.

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

FIG. 15 is a flowchart showing emission 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 the temperature change start recorded in step ST51, and the recording of the temperature change end timing 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 discharging 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. Identify the location 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, the control unit 150 specifies the timing for switching the discharge tray 902 by the discharge switching unit 903 based on the timing determined in step ST63 (step ST64).

When the timing determined in step ST63 does not match the timing at which the sheet S is cut by the cutting unit 90, the control unit 150 specifies the switching timing in step ST64 so that the sheet S3 does not mix with the sheet S1 and the sheet S2. .. 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 deviate from the cutting position where the cutting portion 90 cuts the sheet S. More specifically, it means that one 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 portion 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 accommodated in the discharge tray 902 accommodating the sheet S1. Similarly, the control unit 150 specifies the switching timing so that the mixed sheet is not accommodated in the discharge tray 902 accommodating the sheet S2. The control unit 150 may accommodate 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 the 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 process. If 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 sheet or the discharge tray 902 containing the sheet S3 to the supply unit 10 or the coarse crushing unit 12. You may. Further, the discharge tray 902 containing the mixed sheet and the sheet S3 may be notified to the user by the notification unit 164 or the like.

As described above, in the sheet manufacturing apparatus 100 of the first embodiment, the manufacturing unit 102 that manufactures the sheet S, the operation detecting unit 153 that receives the input of the type of the sheet S manufactured by the manufacturing unit 102, and the operation screen 160. And. The sheet manufacturing apparatus 100 has a control unit 150 that sets the 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. The control unit 150 changes the operating conditions of the manufacturing unit 102 when the operation detection unit 153 receives a new input of the type of the sheet S while the seat S is being manufactured by the manufacturing unit 102. Here, the control unit 150 changes the operating conditions according to the type of the sheet S based on the new input received by the operation detection unit 153, and continues the production of 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 accepted in the state where the sheet S is being manufactured, and the seat is seated. The operating conditions for manufacturing S can be changed, and the manufacturing of sheet S can be continued. Therefore, the type of the sheet S to be manufactured can be quickly changed without stopping the operation of manufacturing the sheet S.

The manufacturing unit 102 has a heating unit 84 that heats a material containing fibers and a binder. The control unit 150 sets the temperature of the heating unit 84 as an 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. Thereby, in the apparatus for manufacturing the sheet S by heating the material, the temperature at which the heating is performed while the sheet S is being manufactured can be changed. Therefore, the type of the sheet S can be changed by changing the heating temperature without stopping the operation of manufacturing the sheet S.

The manufacturing unit 102 includes a plurality of stackers 11 containing raw materials containing fibers for each type, and a supply unit 10 for supplying the raw materials from the stackers 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 corresponds to the set type of raw material. The temperature of the heating unit 84 is set. Thereby, the raw material used for manufacturing the sheet S can be changed while the sheet S is being manufactured. Therefore, it is possible to change the type of the sheet S accompanied by the change of the raw material without stopping the operation of manufacturing the sheet S.

The manufacturing unit 102 has a plurality of additive cartridges 501, each containing a different type of binder. The control unit 150 sets one or more additive cartridges 501 to be used as the 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. 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. As a result, in the apparatus for manufacturing the sheet S using the additive (binding material) according to the type of the sheet S to be manufactured, the additive is changed in the state where the sheet S is being manufactured, and the changed additive is used. At the same time, the heating temperature can be changed. Therefore, it is 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. As a result, when the sheet S is produced using a plurality of additives, the additives can be heated at an appropriate temperature, and a high-quality sheet S can be produced.

The control unit 150 sets the operating conditions 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 conditions 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 seat S is being manufactured by the manufacturing unit 102. .. When the production of the sheet S is continued based on the changed operating conditions, the control unit 150 uses the first type (sheet S1) and the second type (sheet S2) of the sheet S manufactured by the manufacturing unit 102. The sheet S (sheet S3) different from the above is 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 conditions for manufacturing the sheet S are changed, the sheet S different from the type corresponding to the input can be distinguished. Therefore, by distinguishing a sheet S having a property different from that of the designated sheet S, such as a sheet S manufactured between the start of the change and the completion of the change, it is easy to obtain a sheet S having a desired quality. Can be taken out.

The manufacturing unit 102 can execute a transport operation for transporting the material related to the manufacture of the sheet S. The control unit 150 sets the operating conditions 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 transfer operation. The input is a new input. As a result, the operating conditions can be changed according to the input during the transfer operation of transporting the material related to the manufacture of the sheet S.

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

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

The sheet manufacturing apparatus 101 has a configuration in which a winding unit 98 is provided in place of the cutting unit 90 and the discharging unit 97. Except for this difference, the sheet manufacturing apparatus 100 described in the first embodiment has the same configuration as that of the sheet manufacturing apparatus 100. Therefore, the common configuration is designated by the same reference numerals and the description thereof will be omitted.

The manufacturing unit 102a (sheet manufacturing unit) included in the sheet manufacturing apparatus 101 does not include the cutting unit 90. Therefore, the sheet S pressurized and heated by the sheet forming unit 80 is discharged from the manufacturing unit 102a in an uncut state. The sheet manufacturing apparatus 101 includes a winding unit 98 that winds up the uncut sheet S.

The take-up portion 98 includes a take-up roll 911 that winds up the sheet S, and tension rollers 912, 913, and 914 that remove the slack of the sheet S between the take-up roll 911 and the sheet forming portion 80. The tension rollers 912 and 914 are rotatably installed in the transport path of the sheet S, and a tension roller 913 installed so as to give a predetermined tension to the sheet S is arranged between the tension rollers 912 and 914. The tension roller 913 is movable relative to the tension rollers 912 and 914, and is tampered with by an urging means such as a spring to give tension to the seat S.

Further, a marking portion 99 is arranged between the sheet forming portion 80 and the tension rollers 912, 913, and 914.

The marking unit 99 adds a mark (image, symbol, character, etc.) to a predetermined position on the front surface or the back surface of the sheet S by means such as ink or embossing. Specifically, it has an additional portion (not shown) that contacts the sheet S to add a mark, and an actuator or the like (not shown) that presses the additional portion against the sheet S. For example, the marking unit 99 attaches a mark that can be identified by visible light with ink. Alternatively, the marking portion 99 may be marked with a material that is indistinguishable from visible light and emits fluorescence when exposed to ultraviolet light. In the direction orthogonal to the transport direction F of the sheet S, the position where the marking portion 99 adds the mark is arbitrary, for example, it can be an end position, and is a position cut off by the cutting portion 90 (FIG. 1). You may.

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) to rotate and take up the seat S. The take-up motor is connected to the control device 110 by the drive unit I / F 115 (FIG. 4) and rotates under the control of the control unit 150. The take-up roll 911 is rotated by a take-up 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 steps ST61 and ST62 of FIG.

The control unit 150 determines the timing at which the boundary specified in step ST62 passes through the marking unit 99 (step ST81). The control unit 150 controls the actuator or the like of the marking unit 99 to add a mark at the timing specified in step ST62. As a result, in the sheet S, a mark is added by the marking portion 99 to each of the boundary between the sheet S1 and the sheet S3 and the boundary between the sheet S3 and the sheet S2. After the necessary mark is added, the control unit 150 ends the discharge control. If 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 notify the user by the notification unit 164 or the like at the timing when the mark is added by the marking unit 99.

Similar to the sheet manufacturing apparatus 100, the sheet manufacturing apparatus 101 according to the second embodiment is applied with the sheet manufacturing apparatus and the control method of the sheet manufacturing apparatus of the present invention, and the same effect as that of the sheet manufacturing apparatus 100 can be obtained. .. Then, in the sheet manufacturing apparatus 101, in the configuration in which the sheet S is wound without being cut, the wound sheet S can be given a mark indicating the boundary between the sheets S1, S2, and S3. Thereby, in the sheet S wound on the winding roll 911, the part corresponding to the type set by the operation screen 160 can be specified.

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