  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. Note that the embodiments described below do not limit the contents of the present invention described in the claims. Further, not all of the configurations described below are necessarily essential configuration requirements of the present invention.

[1. First embodiment]
[1-1. Overall configuration of sheet manufacturing apparatus]
FIG. 1 is a schematic view showing a configuration of a sheet manufacturing apparatus 100 according to a first embodiment to which the present invention is applied.
The sheet manufacturing apparatus 100 corresponds to the fiber raw material regenerating apparatus of the present invention, and executes a regenerating process of fiberizing a raw material containing fibers and regenerating into a new sheet. The sheet manufacturing apparatus 100 manufactures sheets of a plurality of types by disintegrating the raw material in a dry state to form fibers, and then applying pressure, heating, and cutting. Here, by mixing various additives with the fiberized raw material, the bonding strength and whiteness of the sheet can be improved, and functions such as color, smell and flame retardancy can be added according to the application. be able to. In addition, by controlling the density, thickness, size, and shape by the sheet manufacturing apparatus 100 and molding, it is possible to manufacture and sell various types of sheets. As sheets, in addition to sheet-like products such as A4 and A3 printing sheets, cleaning sheets (floor cleaning sheets, etc.), oil stains sheets, toilet cleaning sheets, etc. It is possible to manufacture.

  The sheet manufacturing apparatus 100 includes the feeding unit 10, the crushing unit 12, the defibrating unit 20, the sorting unit 40, the first web forming unit 45, the rotating body 49, the mixing unit 50, the depositing unit 60, the second web forming unit 70, A conveyance unit 79, a sheet forming unit 80, and a cutting unit 90 are provided. The sheet manufacturing apparatus 100 further includes a control device 110 that controls each part of the sheet manufacturing apparatus 100.

  The sheet manufacturing apparatus 100 includes humidifying units 202, 204, 206, 208, 210, and 212 for the purpose of humidifying the raw material and / or humidifying the space in which the raw material moves. The specific configuration of the humidifying units 202, 204, 206, 208, 210, and 212 is arbitrary, and may be a steam type, a vaporization type, a warm air vaporization type, an ultrasonic type, or the like.

  The humidifying units 202, 204, 206, and 208 of the present embodiment are vaporization type or warm air vaporization type humidifiers, and have a filter (not shown) for infiltrating water, and by passing air through the filter, Supply humidified air with high humidity. The humidifying units 210 and 212 of the present embodiment are ultrasonic humidifiers, and have a vibrating unit (not shown) that atomizes water, and supplies mist generated by the vibrating unit.

  The supply unit 10 supplies, to the crushing unit 12, the raw material MA from which the sheet manufacturing apparatus 100 manufactures a sheet. The operation of the supply unit 10 corresponds to the raw material supply process. The raw material MA should just contain a fiber, for example, a paper, a pulp, a pulp sheet, the cloth containing a nonwoven fabric, or textiles etc. are mentioned. The raw material of the sheet manufacturing apparatus 100 may be used, such as waste paper (so-called waste paper), or may be unused. Below, the case where the sheet manufacturing apparatus 100 uses waste paper as a raw material is mentioned as an example, and is demonstrated.

  The supply unit 10 includes a tray (not shown) that accommodates the material MA input by the user, a roller (not shown) that delivers the material MA from the tray, and a motor (not shown) that drives the roller. The supply unit 10 feeds the raw material MA to the crushing unit 12 by the operation of the motor.

  The crushing unit 12 includes a pair of crushing blades 14 for cutting the raw material MA supplied from the supply unit 10, and a chute (also referred to as a hopper) 9 for receiving coarse fragments cut and dropped by the crushing blade 14. Equipped with The crushing unit 12 cuts the raw material MA supplied from the supply unit 10 in the air (that is, in the air) with the crushing blade 14 (also referred to as crushing) in air such as air (i.e., in the air) to form crushing pieces. The crushing part 12 can be made into the structure similar to what is called a shredder, for example. The shape and size of the coarse fragments are arbitrary, as long as they are suitable for the disintegration processing in the disintegration unit 20. For example, the crushing unit 12 cuts the raw material MA into pieces of paper having a size of 1 to several cm square or less. The cut pieces of paper may be, for example, square or rectangular, and need not be limited to the exact shape. The chute 9 has, for example, a tapered shape in which the width gradually narrows in a direction (progressing direction) in which the coarse fragments flow, and is connected to the pipe 2 communicating with the defibrating unit 20. The crushed fragments cut by the crushing blade 14 are collected by the chute 9 and transferred (conveyed) to the defibrating unit 20 through the pipe 2.

  Humidified air is supplied by the humidifying unit 202 to the chute 9 or its vicinity, and the phenomenon that the coarse debris is adsorbed on the inner surface of the chute 9 or the tube 2 by static electricity is suppressed. Further, since the crushed material is transferred to the defibrating unit 20 together with the air of high humidity, the effect of suppressing the adhesion of the defibrated material MB inside the defibrating unit 20 can also be expected. Here, the humidified air may be supplied from the humidifying unit 202 to the crushing blade 14 so as to discharge the raw material MA, or an ionizer may be provided in the crushing unit 12 and the defibrating unit 20 to perform the charge removal.

  The defibrating unit 20 fibrillates the coarse fragments cut by the crusher 12 to generate a defibrated material MB. Here, "disintegrate" refers to disaggregation of a raw material (which refers to coarse fragments and also referred to as a disaggregated material) in which a plurality of fibers are bound into one fiber. The defibrating unit 20 also has a function of separating substances such as resin particles, ink, toner, and anti-smearing agents attached to the raw material from fibers. What passed through the defibrating unit 20 is referred to as "defibrated material". In addition to disentangled fibrils, disentangled objects are resin particles (resin for binding multiple fibers) particles separated from the fibers when disentangling the fibers, ink, toner, etc. It may contain additives such as coloring agents, anti-smear agents, paper strength agents and the like. Moreover, the shape of the component which comprises disentanglement thing MB is string shape and a flat string (ribbon) shape. The fibers contained in the defibrated material MB may not be entangled with other fibers, may be in an independent state, or may be entangled with other fibers in a lumped state (so-called "dama") . The operation of the defibrating unit 20 corresponds to a defibrating process.

The defibrating unit 20 fibrillates in a dry manner. Here, performing processing such as disintegration in a liquid, not in the air but in the atmosphere or the like is called dry processing. The defibrating unit 20 can be configured using, for example, a defibrator such as an impeller mill. Specifically, the defibrating unit 20 includes a rotor (not shown) that rotates at high speed, and a liner (not shown) located on the outer periphery of the rotor. In this configuration, coarse fragments cut in the coarse portion 12 are sandwiched between the rotor of the defibrating portion 20 and the liner to be broken.
In addition, the defibrating unit 20 generates an air flow by the rotation of the rotor. By this air flow, the defibrating unit 20 sucks the coarse fragments from the pipe 2 and conveys the defibrated material MB to the discharge port 24. The defibrated material MB is delivered from the outlet 24 to the pipe 3 and transferred to the processing unit 30 through the pipe 3.

  The processing unit 30 is a device that sorts the defibrated material MB (material to be separated) flowing in from the pipe 3 according to the size, and can also be called a separation device (separator). Specifically, the processing unit 30 separates the defibrated material MB into deinking material MC having a size equal to or greater than a predetermined size, and dust MD that does not satisfy the predetermined size. The dust MD contains particles of the above-described colorant, additives, etc., short fibers not suitable for the production of the sheet S described later, and the like, and is not used for the production of the sheet S. Further, the deinking raw material MC mainly contains fibers, and mainly contains fibers having a length suitable for producing the sheet S. That is, the processing unit 30 separates the defibrated material MB into a deinking raw material MC containing fibers suitable as a raw material for producing the sheet S, and dust MD as the other component.

  In the following description, the vertical (vertical) direction in the installation state of the sheet manufacturing apparatus 100 is indicated by reference signs UP (upper) and DN (lower) in the drawing. The upper UP and the lower DN specify at least the upper and lower sides of the processing unit 30 in the components of the sheet manufacturing apparatus 100. As shown in FIG. 1, since the pipe 3 is connected to the lower side DN of the processing unit 30 and the pipe 4 is connected to the upper side UP, the inside of the processing unit 30 is disintegrated from the lower side DN to the upper side UP The thing MB flows.

  The processing unit 30 is connected to a compressed gas supply unit 220 that supplies compressed gas. The compressed gas supply unit 220 supplies a high pressure compressed gas obtained by compressing a gas such as air to the processing unit 30. The gas supplied by the compressed gas supply unit 220 is air or dry air obtained by removing water from air. The compressed gas supply unit 220 may be configured to supply an inert gas such as nitrogen gas, helium gas, or argon gas, or may be configured to supply another gas. The compressed gas supply unit 220 is, for example, a compressed gas supply device including a gas cylinder (not shown) in which the above-described gas is stored at high pressure, and a pressure reducing device (regulator) that supplies the gas adjusted from the gas cylinder. Also, for example, the compressed gas supply unit 220 is a compressor (compressor) that compresses and supplies air or other gas. The compressed gas supply unit 220 may be a pipe to which high pressure gas is supplied from a compressor installed outside the sheet manufacturing apparatus 100.

The processing unit 30 has a conveying pipe 31 (conveying path, pipe) communicating with the pipe 3 and the pipe 4 and is provided with a separation unit 300 (separation part) for separating the defibrated material MB conveyed by the conveying pipe 31 Configured
In the transport pipe 31, a mesh plate 31C (FIG. 2) functioning as a sieve is disposed. The mesh plate 31C is formed with an opening of a predetermined size as described later. The mesh plate 31 </ b> C is connected to the pipe 5, and the pipe 5 is connected to the collection blower 28 via a dust collection unit 27 described later.

  In the processing unit 30, the separation unit 300 sprays the compressed gas supplied by the compressed gas supply unit 220 onto the defibrated material MB flowing from the tube 3 into the transport tube 31 to make the fibrillated material MB a mesh plate 31C. The component passing through the opening is separated from the component not passing through the opening. Among the components contained in the defibrated material MB, a component which does not pass through the mesh plate 31C, that is, a component having a large size, is sent to the pipe 4 together with the carrier air flowing through the pipe 3 as the deinking material MC. Further, among the components contained in the defibrated material MB, the component passing through the mesh plate 31C, that is, the component having a small size is sent to the pipe 5 as dust MD.

  Therefore, the defibrated material MB that has been defibrated by the defibrating unit 20 is sorted by the processing unit 30 into the deinking material MC and the dust MD, the deinking material MC is sent to the pipe 4, and the dust MD is Sent to

  The dust collection unit 27 connected to the pipe 5 is a filter-type or cyclone-type dust collection device, and separates fine particles from the air flow. The collection blower 28 (suction unit) is a blower that sucks air from the dust collection unit 27, and dust MD is drawn from the processing unit 30 to the pipe 5 by the suction force of the collection blower 28. Sent. The collection blower 28 collects the dust MD sucked through the pipe 5, and the air having passed through the dust collection unit 27 is discharged to the pipe 29 by the collection blower 28.

  The sheet manufacturing apparatus 100 includes a defibrating unit blower 26 that is an air flow generating device. The defibrating unit blower 26 is a blower attached to the pipe 4 to suck air from the processing unit 30 and blow the air to the sorting unit 40. The deinking raw material MC separated by the processing unit 30 is conveyed to the sorting unit 40 by the air flow generated by the defibrating unit blower 26.

  The sorting unit 40 has an inlet 42, and the deinking raw material MC separated and deinked by the processing unit 30 flows into the inlet 42 together with the air flow. The sorting unit 40 sorts the deinked raw material MC flowing into the inlet 42 according to the length of the fiber. Specifically, the sorting unit 40 selects a component including fibers having a size equal to or less than a predetermined size among the components of the deinking raw material MC as a first sorting material, and performs a second sorting of a component including fibers larger than the first sorting material. Sort as a thing. The first sorted product mainly contains the fibers separated by the processing unit 30. The second sorted matter includes, for example, large fibers, unbroken pieces (eg, coarse fragments not sufficiently broken), and the like.

The sorting unit 40 has a drum portion 41 and a housing portion 43 for housing the drum portion 41.
The drum portion 41 is a cylindrical structure having a mesh, and the mesh may be a filter or a screen. For example, it is possible to use a wire mesh, an expanded metal obtained by extending a metal plate with cuts, and a punching metal in which holes are formed in a metal plate by a press machine or the like. The drum unit 41 functions as a sieve by being rotationally driven by a motor (not shown), and sorts the first sorted matter smaller than the mesh size and the second sorted matter larger than the mesh size. That is, by the rotation of the drum unit 41, the first sorted matter falls downward from the mesh of the drum unit 41. The second sorted matter which can not pass through the mesh of the drum unit 41 is led to the discharge port 44 by the air flow flowing into the drum unit 41 from the introduction port 42 and is sent out to the pipe 8.

  The tube 8 is connected to the inside of the drum portion 41 and the tube 2, and the second sorted matter which has flowed from the drum portion 41 into the tube 8 passes through the tube 2 together with the coarse fragments cut by the coarse portion 12 It is led to the inlet 22 of the section 20. Thereby, the second sorted matter is returned to the defibrating unit 20 and subjected to defibration processing.

The first sorted matter sorted by the drum unit 41 disperses in air and descends toward the mesh belt 46 of the first web forming unit 45 located below the drum unit 41.
In addition to the cylindrical or drum-shaped sieve, for example, a flat-plate-like sieve may be driven in the in-plane direction, as long as the sorting unit 40 can sort the first sorting unit and the second sorting unit as sieves. (1) It may be configured to sift a sort or the like.

The first web forming unit 45 includes a mesh belt 46, a roller 47, and a suction unit 48.
The mesh belt 46 is an endless belt and is suspended by three rollers 47 and conveyed by the rollers 47 in a direction indicated by an arrow V1 in the figure. The surface of the mesh belt 46 is constituted by a net in which openings of a predetermined size are arranged. Among the first sorted matter falling from the sorting unit 40, fine particles having a size passing through the mesh of the mesh belt 46 fall below the mesh belt 46. On the other hand, fibers of a size which can not pass through the mesh of the mesh belt 46 are deposited on the mesh belt 46 and conveyed together with the mesh belt 46 in the direction of the arrow V1.

  Thus, the deinking raw material MC defibrillated by the defibrating unit 20 is sorted by the sorting unit 40 into the first sorted matter and the second sorted matter, and the second sorted matter is returned to the defibrated unit 20 . Further, the dust MD is removed from the first sorted matter by the first web forming unit 45. The remainder obtained by removing the dust MD 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 fine particles falling from the mesh belt 46 include relatively small particles and low density among the deinking raw materials MC. For example, the resin, the coloring agent, and the additive taken out from the coarse fragments in the defibrating unit 20 Etc., and correspond to the above-mentioned dust MD. These fine particles are removal materials not used in the production of the sheet S. Since the deinking raw material MC is separated from the dust MD in the processing unit 30, it has a composition that hardly contains the dust MD. When the deinking raw material MC is sucked through the mesh belt 46, the content rate of the dust MD in the deinking raw material MC can be further reduced, and the first web W1 containing fibers with high whiteness can be obtained. it can.

  The suction unit 48 sucks air from below the mesh belt 46. The suction unit 48 is connected to the dust collection unit 27, and the components that have passed through the mesh belt 46 are collected by the dust collection unit 27.

  As described above, the dust collection unit 27 collects the dust MD separated by the processing unit 30 and the dust MD separated by the first web forming unit 45. The air that has passed through the dust collection unit 27 is exhausted by the collection blower 28 via the pipe 29.

  The pipe 29 discharges the air discharged by the collection blower 28 to the inside or the outside of the apparatus of the sheet manufacturing apparatus 100. The air discharged by the collection blower 28 may be sent to, for example, the humidifying units 202, 204, 206, and 208 configured by a vaporization type humidifier. The sheet manufacturing apparatus 100 separates the air that has passed through the defibrating unit 20 and the air that has passed through the sorting unit 40 from the first web W 1 and exhausts the air by the collection blower 28. Therefore, the air flow containing the heat generated in each portion including the defibrating unit 20 can be discharged to the pipe 29 without being sent to the mixing unit 50. Therefore, the effect of exhausting the heat generated in the defibrating unit 101 including the defibrating unit 20 can be expected.

  Further, humidified air is supplied by the humidifying unit 204 to the space including the drum unit 41. By humidifying the first sorted matter by the humidified air, adhesion of the first sorted matter to the mesh belt 46 due to electrostatic force can be weakened, and an effect of facilitating peeling of the first web W1 from the mesh belt 46 can be expected. In addition, the inner wall of the rotating body 49 and the housing portion 43 has an effect of suppressing the adhesion of the first sorted matter by the electrostatic force. Furthermore, the effect of improving the efficiency of suctioning the removed material by the suction unit 48 can be expected.

  In the sheet manufacturing apparatus 100, the configuration for sorting and separating the first sorted matter and the second sorted matter is not limited to the sorting unit 40 including the drum unit 41. For example, a configuration may be adopted in which the deinking raw material MC separated by the processing unit 30 is classified by a classifier. As a classifier, for example, a cyclone classifier, an elbow jet classifier, or an Eddie classifier can be used. Using these classifiers, it is possible to sort and separate the first sort and the second sort. Furthermore, a configuration to separate and remove the relatively small or low density components of the deinking raw material MC (resin particles, coloring agents, additives, etc.) among the components of the deinking raw material by the above-mentioned classifier realizable. For example, fine particles contained in the first sort may be removed from the first sort by the classifier. In this case, the second sorted matter may be returned to, for example, the defibrating unit 20, the removed matter may be collected by the dust collecting unit 27, and the first sorted matter excluding the removed matter may be sent to the pipe 54. . Further, in the sheet manufacturing apparatus 100, the configuration for removing the removal material from the first sorted matter is not limited to the mesh belt 46, and the configuration described above can be used.

  On the downstream side of the sorting unit 40 in the transport path of the mesh belt 46, air containing mist is supplied by the humidifying unit 210. The humidifying unit 210 lowers the mist toward the first web W1 to supply moisture to the first web W1. With this configuration, the amount of water contained in the first web W1 can be adjusted, and adsorption of fibers to the mesh belt 46 due to static electricity can be suppressed.

  The rotating body 49 loosens the fibers of the first web W1 and processes the resin in a state easy to mix in the mixing unit 50 described later. 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 divided by the rotating body 49 to become a subdivided body P. The rotating body 49 has, for example, a plate-like blade and is in the form of a rotating blade that rotates. The subdivisions P are transferred to the mixing unit 50 through the pipe 7.

  Humidified air is supplied to the space including the rotating body 49 by the humidifying unit 206, and adsorption of fibers to the inside of the tube 7 and the rotating body 49 due to static electricity is suppressed. Moreover, the influence by static electricity can be suppressed also in the mixing part 50 by supplying humidified air to the mixing part 50 from the pipe | tube 7. FIG.

  The mixing unit 50 includes an additive supply unit 52 for supplying an additive containing a resin, a pipe 54 through which an air flow containing the subdivision P flows, and a mixing blower 56, and fibers constituting the subdivision P (first sorting Add the resin-containing additives to the

  In the additive supply unit 52, an additive cartridge 52a for accumulating the additive is set. The additive cartridge 52 a may be removable from the additive supply unit 52. The additive supply unit 52 includes an additive removal unit 52b that removes the additive from the additive cartridge 52a, and an additive insertion unit 52c that discharges the additive removed by the additive removal unit 52b to the pipe 54.

  The additive removal unit 52b includes a feeder (not shown) for feeding out the additive consisting of fine powder or fine particles in the inside of the additive cartridge 52a, and removes the additive from part or all of the additive cartridge 52a. The additive removed by the additive removal unit 52b is sent to the additive insertion unit 52c.

  The additive input unit 52c contains the additive extracted by the additive extraction unit 52b. The additive loading unit 52c is provided with a shutter (not shown) that can be opened and closed at a connection with the tube 54, and the additive taken out by the additive removal unit 52b is fed out to the tube 54 by opening the shutter. The shutter of the additive input portion 52c has an effect of preventing the additive from being excessively sucked out of the additive supply portion 52 by the negative pressure generated by the air flow of the pipe 54.

  The additive supplied by the additive supply unit 52 includes a resin that melts by heating to bind 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. In addition, polyphenylene ether, polybutylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyetheretherketone and the like may be used. These resins may be used alone or in combination as appropriate. That is, the additive may contain a single substance, or may be a mixture, and may contain multiple types of particles, each consisting of a single or multiple substances. Further, the additive may be in the form of fiber or powder.

  Further, the additive supplied by the additive supply unit 52 may be a coloring agent for coloring the fibers, aggregation of the fibers, aggregation of the resin or the like depending on the type of the sheet to be manufactured, in addition to the resin for binding the fibers. And a flame retardant to make the fibers and the like hard to burn. Further, the additive not containing a colorant may be colorless or pale to an extent that can be regarded as colorless, or may be white. Additives containing coloring agents (including white and other colors) correspond to so-called coloring materials.

The type and number of additives used by the sheet manufacturing apparatus 100 are arbitrary, and the additive supply unit 52 is mounted with an additive cartridge 52a corresponding to the type of additive to be used. Further, the sheet manufacturing apparatus 100 may use only a part of the additive cartridge 52a mounted to the additive supply unit 52, or may use all of them.
In the present embodiment, six additive cartridges 52 a are attached to the additive supply unit 52 as an example. The six additive cartridges 52a include an additive cartridge 52a containing an additive that is colorless or light enough to be regarded as colorless, and an additive cartridge 52a containing an additive capable of coloring the fibers white. In addition, it includes an additive cartridge 52a that contains an additive capable of coloring the fibers into C (cyan), M (magenta), and Y (yellow) colors.

  The amount by which the additive removal unit 52b removes the additive from each of the additive cartridges 52a is controlled by the control device 110. By controlling the additive supply unit 52 by the control device 110, the sheet manufacturing apparatus 100 operates to manufacture the sheet S without coloring the fibers constituting the subdivided body P, and manufactures the sheet S by coloring the fibers. Can do the Also, by supplying the additive from any one of the additive cartridges 52a, the fibers can be colored in white, C, M, and Y colors. For example, whiteness can be improved by mixing white additives into the fibers. Further, the fibers can be colored in an intermediate color by combining and mixing the additives contained in the plurality of additive cartridges 52a.

  The additive supplied from the additive supply unit 52 is conveyed by the air flow generated by the mixing blower 56 while being mixed with the fibers constituting the subdivided body P, and passes through the inside of the mixing blower 56 through the pipe 54. The subdivisions P are loosened in the process of flowing inside the pipe 7 and the pipe 54 to become finer fibers. The fibers of the subdivision P and the additives are mixed by the action of the air flow generated by the mixing blower 56 and / or the rotating body such as the blades of the mixing blower 56, and the mixture is transferred to the deposition unit 60 through the pipe 54. Ru.

  The mechanism for mixing the first sorted matter and the additive is not particularly limited, and may be stirring with a blade rotating at a high speed, or using rotation of the container like a V-type mixer. These mechanisms may be installed before or after the mixing blower 56.

  The mixture that has passed through the mixing unit 50 is introduced into the inlet 62 of the deposition unit 60. The deposition section 60 loosens the fibers of the mixture and descends to the second web forming section 70 while dispersing in air. Here, when the resin of the additive supplied from the additive supply unit 52 is in the form of fibers, these fibers are also loosened by the deposition unit 60 and descend to the second web forming unit 70.

  The deposition unit 60 includes a drum unit 61 and a housing unit 63 that accommodates the drum unit 61. The drum unit 61 is, for example, a cylindrical structure configured similarly to the drum unit 41, has a mesh similar to that of the drum unit 41, is rotationally driven by a motor, and functions as a sieve. In addition, the "sieve" of the drum part 61 does not need to have a function which screens a specific target object. That is, the “sieve” used as the drum unit 61 means that the mesh unit is equipped with a net, and the drum unit 61 may lower all of the mixture introduced to the drum unit 61.

  The second web forming unit 70 is disposed below the drum unit 61. The second web forming unit 70 includes, for example, a mesh belt 72, a roller 74, and a suction mechanism 76.

  The mesh belt 72 is an endless belt and is suspended by a plurality of rollers 74, and is conveyed in the direction indicated by the arrow V2 in the figure 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, and the surface thereof is formed of a net in which openings of a predetermined size are arranged. Among particles falling from the deposition section 60, fine particles having a size that passes through the mesh of the mesh belt 72 fall below the mesh belt 72. On the other hand, the fibers of a size which can not pass through the mesh of the mesh belt 72 are deposited on the mesh belt 72 and conveyed together with the mesh belt 72 in the direction of the arrow V2. The mesh of the mesh belt 72 is fine and can be sized so as not to pass most of the fibers and particles falling from the drum portion 61. With this configuration, the passing material that has passed through the mesh of the drum unit 61 is deposited on the second web forming unit 70, and the deposit is the second web W2.

  The suction mechanism 76 includes a suction blower 77 provided below the mesh belt 72 and causes the suction mechanism 76 to generate an air flow from the accumulation unit 60 toward the mesh belt 72 by the suction force of the suction blower 77. The suction mechanism 76 suctions the mixture dispersed in the air by the deposition unit 60 onto the mesh belt 72, so that the effect of promoting the formation of the second web W2 can be expected. In addition to the effect of increasing the discharge speed from the deposition unit 60, an effect of preventing the fibers and additives of the deinking raw material MC from being entangled during falling can be expected due to the downflow formed in the falling path of the mixture.

  The suction blower 77 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 collection unit 27, and the removal component contained in the air sucked by the suction mechanism 76 may be collected.

Humidified air is supplied to the space including the drum unit 61 by the humidification unit 208. By humidifying the inside of the deposition unit 60 by this humidified air, adhesion of the fibers and particles to the housing portion 63 by electrostatic force is suppressed, and the fibers and particles are quickly dropped to the mesh belt 72, and the second shape of the preferable shape The web W2 can be formed.
Further, in the conveyance path of the mesh belt 72, air containing mist is supplied to the downstream side of the accumulation unit 60 by the humidification unit 212. As a result, the amount of water contained in the second web W2 is adjusted, and adsorption of fibers to the mesh belt 72 due to static electricity is suppressed.

  The second web W2 formed by the deposition unit 60 and the second web forming unit 70 (web forming step) is separated from the mesh belt 72 by the conveying unit 79 and conveyed to the sheet forming unit 80. The transport unit 79 includes, for example, a mesh belt 79a, a roller 79b, and a suction mechanism 79c.

  The suction mechanism 79 c includes a blower (not shown) and generates an upward air flow on the mesh belt 79 a by the suction force of the blower. By this air flow, the second web W2 is separated from the mesh belt 72 and is attracted to the mesh belt 79a. The mesh belt 79 a is moved by the rotation of the roller 79 b and conveys the second web W 2 to the sheet forming unit 80.

  In the sheet forming unit 80, heat is applied to the fibers of the deinking raw material MC contained in the second web W2 and the additive to mutually bond a plurality of fibers in the mixture through the resin contained in the additive. Put it on. Specifically, the sheet forming unit 80 includes a pressing unit 82 that presses the second web W2, and a heating unit 84 that heats the second web W2 pressed by the pressing unit 82. The pressing unit 82 is constituted by a pair of calendar rollers 85 and 85, and nips and presses the second web W2 with a predetermined nip pressure to densify the second web W2 and transport it toward the heating unit 84. . The heating unit 84 includes a pair of heating rollers 86 and 86, and heats the second web W2 pressed by the calendar rollers 85 and 85 to form a sheet S.

  The cutting unit 90 cuts the sheet S formed by the sheet forming unit 80. The cutting unit 90 according to the present embodiment cuts the sheet S in a direction parallel to the conveyance direction F, and a first cutting unit 92 that cuts the sheet S in a direction intersecting the conveyance direction of the sheet S indicated by the code F in the drawing. And a second cutting portion 94. By cutting at the cutting unit 90, a single-cut sheet S of a predetermined size is formed. The cut sheet S cut by the cutting unit 90 is stored in the discharge unit 96. The discharge unit 96 includes a tray or stacker for storing the manufactured sheets, and the sheet S discharged to the tray can be taken out and used by the user.

  Each part of the sheet manufacturing apparatus 100 described above constitutes a defibrating unit 101 and a regenerating unit 102. The defibrating unit 101 includes at least the feeding unit 10 and the defibrating unit 20, and may include the sorting unit 40 and the first web forming unit 45. The fibrillation processing unit 101 manufactures the first web W1 in which the deinking material MC or the deinking material MC is formed in a web form from the material MA. It is also possible to take out and store the product of the disintegration processing unit 101 from the sheet manufacturing apparatus 100 without transferring it to the rotating body 49. Also, the product may be enclosed in a predetermined package to be in a transportable and tradable form.

  The regenerating unit 102 is a functional unit that regenerates the product manufactured by the disintegrating unit 101 into a sheet S, and the mixing unit 50, the mixing unit 50, the second web forming unit 70, the conveying unit 79, and the sheet forming unit 80. And the cutting part 90, and may include the rotating body 49. In addition, the additive supply unit 52 may be included. In the sheet manufacturing apparatus 100, the defibration processing unit 101 and the regenerating unit 102 may be configured integrally or separately. In this case, the defibration processing unit 101 corresponds to the fiber material regenerating apparatus of the present invention. The regenerating unit 102 corresponds to a sheet forming unit that forms the deinking material MC into a sheet shape. Moreover, it can be said that all of these correspond to the processing unit.

[1-2. Configuration of separation unit]
FIG. 2 is a perspective view of the processing unit 30. FIG. FIG. 3 is a cross-sectional view of the processing unit 30, and shows a cross-sectional view in a cross section perpendicular to the axial center of the tube 23. FIG. 4 is a longitudinal cross-sectional view of the processing unit 30, and shows a cross-sectional view in a cross-section including the axial center of the tube 23. As shown in FIG. The configuration of the processing unit 30 will be described with reference to FIGS. 2 to 4.

  The processing unit 30 (fiber processing apparatus) has a transport pipe 31 and a separation unit 300 attached to the transport pipe 31. The transport pipe 31 is a hollow straight pipe, and the upstream end 31A which is one end of the transport pipe 31 is connected to the pipe 3 and the downstream end 31B which is the other end is connected to the pipe 4 Ru. The fibrillated material MB flows into the inside of the transfer pipe 31 from the pipe 3 together with the transfer air flow FL, and the transfer air flow FL flows out to the pipe 4 from the downstream end portion 31B.

  A mesh plate 31 </ b> C (collection unit, mesh unit) is provided on part of the wall surface of the transfer pipe 31. The mesh plate 31C has an opening 31D of a predetermined size and functions as a sieve. For example, the mesh plate 31 </ b> C is formed in a plate shape having an opening 31 </ b> D, and is fitted into a hole formed in the side wall of the transport pipe 31. In this case, as the mesh plate 31C, for example, a wire mesh, an expanded metal obtained by extending a metal plate with cuts, or a punching metal formed by forming a hole in a metal plate with a press machine or the like can be used.

  The size of the opening 31D is arbitrary, but can be, for example, about 0.1 mm. Further, the shape of the opening 31D is arbitrary, and may be an opening formed as a gap between a plurality of wires or an opening formed in a flat plate like a punching metal. The shape of the opening 31D may be polygonal, circular or elliptical. The size of the opening 31D described above can be defined as the opening width of the longest portion in the opening 31D. The shape of the mesh plate 31C is also arbitrary, and may be rectangular, circular, elliptical, various geometric shapes, or shapes having no symmetry.

  In the transport pipe 31, particles and fibers of a size that can pass through the opening 31 </ b> D pass through the mesh plate 31 </ b> C and come out of the transport pipe 31. Here, a virtual axis located at the center of the transfer pipe 31 is shown by a virtual line in the figure. The virtual axis AX is parallel to the flow direction of the carrier air flow FL in the carrier tube 31.

  The separation unit 300 is attached to the transfer pipe 31 at a position corresponding to the mesh plate 31C in the transfer pipe 31. The separation unit 300 has an outer pipe 310 covering the outer side of the transfer pipe 31, a nozzle head 301 provided on the outer pipe 310, and an exhaust duct 320 communicating with the inside of the outer pipe 310.

The outer pipe 310 is a straight pipe having a diameter larger than that of the transfer pipe 31 and is disposed so that the transfer pipe 31 passes through the inside of the outer pipe 310. Therefore, the transport pipe 31 and the outer pipe 310 constitute a double pipe, and a space 311 is formed between the outer pipe 310 and the discharge duct 320.
The length of the outer pipe 310 in the axial direction AX is shorter than that of the transfer pipe 31. For this reason, the space 311 is opened at the end of the outer tube 310, but the wall 312 is provided on the upstream side of the carrier air flow FL and the wall 313 is provided on the downstream side of the carrier air flow FL so as to close the opening. Be

Further, in the outer pipe 310, an opening 314 is formed at a position facing the mesh plate 31C, and the discharge duct 320 is connected to the opening 314.
Thus, the space 311 formed inside the outer tube 310 is closed by the walls 312 and 313 and the discharge duct 320 and communicates with the inside of the discharge duct 320.
The discharge duct 320 is a hollow pipe connected to the pipe 5.

  In the outer pipe 310, the nozzle head 301 is disposed at a position facing the discharge duct 320 across the virtual axis AX. The nozzle head 301 is disposed to penetrate the inside and the outside of the outer pipe 310, and the tip of the nozzle head 301 penetrates the side wall of the transfer pipe 31 to reach the inside of the transfer pipe 31.

  An air chamber 303 is formed inside the nozzle head 301 (the separated air flow supply unit), and the air chamber 303 communicates with the plurality of nozzles 304 A located in the internal space of the transport pipe 31. The nozzles 304 A are arranged side by side at the tip of the nozzle head 301 to form a nozzle row 304. The arrangement direction of the nozzles 304A is arbitrary, but in the present embodiment, the nozzles 304A are arranged in a direction intersecting with the virtual axis AX to form a nozzle row 304.

  The nozzle 304A is a nozzle that diffuses the gas into the inside of the transfer pipe 31 and blows it out when the air chamber 303 is filled with a high pressure gas. In the nozzle row 304 of the present embodiment, as shown by the arrows in FIGS. 3 and 4 by the plurality of nozzles 304A, a direction extending at an angle θ1 in a plane perpendicular to the virtual axis AX and along the virtual axis AX. The gas is diffused and blown out in the expanding direction at the angle θ2. Here, a range where the gas is blown out from the nozzle array 304 and an air flow is generated is defined as a blowing range 306, and the air flow is indicated by reference numeral 305. That is, in the internal space of the transfer pipe 31, the gas blown out by the nozzle array 304 generates the air flow 305, and the range covered by the air flow 305 is set as the blowing range 306.

  The direction of the air flow 305 is a direction intersecting the transport air flow FL (in other words, a direction intersecting the virtual axis AX). In FIG. 4, the center of the air flow 305 is indicated by a virtual line 305A. In the present embodiment, the air flow center 305A is orthogonal to the virtual axis AX.

  The compressed gas supply pipe 302 is connected to the nozzle head 301. The compressed gas supply pipe 302 is a pipe to which compressed gas is supplied from the compressed gas supply unit 220 (FIG. 1), and is in communication with the air chamber 303. Therefore, the high pressure gas supplied by the compressed gas supply unit 220 is supplied from the compressed gas supply pipe 302 to the air chamber 303, and blown out from the nozzle row 304 into the inner space of the transfer pipe 31 to generate the air flow 305.

  A mesh plate 31 </ b> C is provided on the transport pipe 31 at a position facing the nozzle row 304. Therefore, the air flow 305 reaches the mesh plate 31C, passes through the opening 31D of the mesh plate 31C, and reaches the discharge duct 320. Since the discharge duct 320 is in communication with the pipe 5, the air flow 305 passes through the pipe 5 and reaches the dust collection portion 27 as shown in FIG. 1.

  As described above, the defibrated material MB supplied to the processing unit 30 from the pipe 3 includes fibers of various lengths obtained by fibrillating fibers constituting the raw material MA. These fibers are shown as fibers FB. In addition, the defibrated material MB includes colored or white particles PA which are particles of ink, toner, or additive contained in the raw material MA.

  The defibrated material MB includes dispersed fibers FB and particles PA, and may further include a complex CP in which a plurality of fibers FB are aggregated or entangled. The complex CP includes the damas described above and those smaller than the damas. The composite CP may include particles PA incorporated with the fibers FB. The number of fibers FB constituting the complex CP, the number of particles PA contained in the complex CP, the size of the complex CP, and the like do not matter. In addition, the defibrated material MB may contain coarse fragments or undisintegrated fragments larger than the fibers FB. In this case, the coarse fragments may be taken into the composite CP.

  In the first web forming portion 45, it is easy for the first free web forming portion 45 to have the independently released fiber FB, a state in which the plurality of fibers FB are gently entangled, the free particle PA, or the particle PA attached to the fiber FB Can be separated. That is, in the first web forming unit 45, the fibers FB are deposited on the mesh belt 46, and suction is performed from below the mesh belt 46 by the suction unit 48, thereby recovering the particles PA passing through the processing of the mesh belt 46. The free fibers FB and particles PA can be sorted by the opening of the mesh belt 46, and the particles PA adhering to the fibers FB are pulled away from the fibers FB by the suction force of the suction portion 48.

  On the other hand, it is not easy to take out and separate the particles PA incorporated in the complex CP from the complex CP. In order to take out the particles PA in the complex CP, it is necessary to unravel the fibers FB constituting the complex CP, and further to separate the particles PA from the fibers FB, and it is necessary to exert a strong force on the complex CP. . In addition, in the case where a plurality of complexes CP are assembled to form a larger complex CP, a stronger force is required to break up the complex CP.

The sheet manufacturing apparatus 100 of the present embodiment disentangles the complex CP by the processing unit 30, and removes the particles PA taken in the complex CP.
The processing unit 30 generates an air flow 305 inside the transport pipe 31 by blowing out the compressed gas from the nozzle array 304 of the nozzle head 301. The air flow 305 acts on the defibrated material MB flowing through the transfer pipe 31 together with the transfer air flow FL. In detail, since the air flow 305 flows in a direction intersecting the transport air flow FL, the air flow 305 collides with the complex CP and acts to decompose the complex CP. In addition, the air flow 305 pushes the fibers FB and the composite CP in a direction different from the transport air flow FL, and acts to cause the composite CP and the fibers FB and / or the composite CP and the composite CP to collide. Further, the air flow 305 acts to agitate the defibrated material MB inside the transfer pipe 31. Furthermore, when the air flow 305 directly sweeps the complex CP, the complex CP collides with the side wall of the transport pipe 31, or the air flow 305 stirs the transport air flow FL including the complex CP. It collides with the side wall of the transfer pipe 31. That is, the air flow 305 acts to externally impact the composite CP.

As described above, due to the action of the air flow 305, an external force in a direction different from that of the carrier air flow FL acts on the complex CP, and the complex CP is decomposed. For this reason, particle | grains PA taken in into composite CP will be in the state which can be isolate | separated from fiber FB.
Further, the air flow 305 acts to push the fibers FB and the particles PA transported by the transport air flow FL toward the mesh plate 31C. When the complex CP is disassembled, the fibers FB and the particles PA contained in the complex CP are also flushed by the air flow 305 toward the mesh plate 31C.

As shown in FIG. 3, the mesh plate 31 </ b> C is provided in a range larger than the blowing range 306 in the cross-sectional direction of the transport pipe 31. Further, as shown in FIG. 4, the mesh plate 31 </ b> C is provided in a range larger than the blowing range 306 in the direction of the virtual axis AX.
For this reason, most of the fibers FB, the particles PA, and the composite CP swept by the air flow 305 flow toward the mesh plate 31C. Among these components, a component sized to pass through the opening 31D exits the space 311 through the opening 31D.

  In the space 311, the air flow 321 is generated by the air flow 305 passing through the opening 31D and the suction force of the collection blower 28 (FIG. 1) acting through the pipe 5. The component of the fiber FB that has passed through the opening 31D is transported from the space 311 to the dust collection unit 27 (FIG. 1) by the air flow 321 as dust MD.

  Further, among the components contained in the fiber FB, even if the component having a size not passing through the opening 31D is flowed toward the mesh plate 31C by the air flow 305, the component is collected by the mesh plate 31C and stops in the transport tube 31. These components mainly comprise the fibers FB. These components are transported toward the downstream end 31B by the transport airflow FL, and flow into the pipe 4 as the deinking material MC. The deinking raw material MC is sent to the defibrating unit blower 26 (FIG. 1) through the pipe 4 and conveyed to the sorting unit 40 by the air flow generated by the defibrating unit blower 26.

  As described above, the sheet manufacturing apparatus 100 according to the first embodiment includes the transport pipe 31 that transports the defibrated material MB including the fiber FB by the transport air flow FL, and the separation unit 300 provided in the transport pipe 31. And a processing unit 30 including: Here, the sheet manufacturing apparatus 100 corresponds to a fiber processing apparatus, but the processing unit 30 may correspond to a fiber processing apparatus. The separation unit 300 includes a nozzle row 304 for supplying an air flow 305 for separation, which flows in a direction intersecting the transport air flow FL, to the defibrated material MB transported to the transport pipe 31. Further, the separation unit 300 has an opening 31D which is provided in the transport pipe 31 and discharges the defibrated material MB to the outside of the transport pipe 31, and is provided with a mesh 31C disposed so as to overlap the opening 31D. The meshed 31 C functions as, for example, a collection unit that collects the fibers FB flowed by the separation air flow 305.

  According to this configuration, the defibrated material MB is transported by the transport air flow FL, and the fiber FB is collected by flowing the fiber FB from the transported defibrated material MB by the air flow 305, whereby the fiber FB contained in the defibrated material MB is And fiber FB can be separated from components. As a result, since the air flow 305 intersecting the transport air flow FL can be expected to loosen the dense fibers FB, the fibers FB contained in the defibrated material MB can be separated more reliably from components other than the fibers FB. . Therefore, the fiber FB having a higher degree of whiteness can be taken out from the defibrated material MB.

  The separation unit 300 includes an exhaust duct 320 (duct) communicating with the opening 31D. Therefore, by flowing the air flow after collecting the fibers FB from the defibrated material MB flowed by the air flow 305 to the discharge duct 320, the components other than the fiber FB contained in the defibrated material MB are discharged through the discharge duct 320 Or can be collected. For this reason, it is possible to prevent the component separated from the fiber FB from being mixed again into the fiber FB, and to obtain the fiber FB with higher whiteness.

  Further, the mesh plate 31C is a mesh that collects the fibers FB and allows particles smaller than the fibers FB to flow in the openings 31D. Therefore, the components contained in the defibrated material MB flowed by the air flow 305 can be easily separated according to the size. For this reason, the fiber FB contained in the defibrated material MB and the component smaller in size than the fiber FB can be efficiently separated.

  Moreover, since the nozzle row 304 has the nozzle 304A which blows off the compressed gas to the transport pipe 31, the fiber FB contained in the defibrated material MB can be loosened more reliably. For this reason, fiber FB contained in defibrated material MB can be separated from components other than fiber FB more certainly.

  Further, the nozzle 304A is disposed opposite to the opening 31D in the transport pipe 31, and blows out the compressed gas toward the opening 31D, so components other than the fiber FB contained in the defibrated material MB are directed to the opening by the compressed gas. Can be separated efficiently from the fiber FB.

  Further, since the sheet manufacturing apparatus 100 includes the collection blower 28 (suction unit) for suctioning the gas in the transport pipe 31 from the opening 31 D, components other than the fiber FB contained in the defibrated material MB can be obtained from the transport pipe 31 It can be removed. As a result, it is possible to prevent the component such as the particles PA separated from the fiber FB from being mixed again into the fiber FB, and to obtain the fiber FB with higher whiteness.

  Further, the separation unit 300 includes a plurality of nozzles 304A arranged in the direction intersecting the transport air flow FL in the transport pipe 31. Therefore, the compressed gas can be evenly sprayed from the plurality of nozzles to the defibrated material MB transported in the transport pipe 31, and the fibers FB contained in the deflocculated material MB can be more reliably loosened.

  Further, the transport pipe 31 is constituted by a pipe through which the transport air flow flows, and the separation unit 300 supplies the air flow 305 for separation to the straight pipe portion of the pipe. According to this configuration, the fiber FB can be efficiently extracted from the defibrated material MB transported in the straight pipe portion.

  In addition, the sheet manufacturing apparatus 100 to which the fiber raw material regenerating apparatus of the present invention is applied includes the fibrillation unit 20 that disintegrates the raw material MA containing the fiber FB, and the fibrillated material MB fibrillated by the fibrillation unit 20. And a regenerating unit 102 as a processing unit for processing. The sheet manufacturing apparatus 100 includes, from the defibrating unit 20 to the regenerating unit 102, a transport pipe 31 that transports the defibrated material MB by the transport air flow FL, and a separation unit 300 provided in the transport pipe 31. The separation unit 300 includes a nozzle row 304 for supplying an air flow 305 for separation, which flows in a direction intersecting the transport air flow FL, to the defibrated material MB transported to the transport pipe 31. Furthermore, the transport pipe 31 has an opening 31D for discharging the defibrated material MB out of the transport pipe 31, and is provided with a mesh plate 31C for collecting the fibers FB flowed by the air flow 305.

  With this configuration, the fibrillated material MB obtained by disintegrating the raw material MA is transported by the carrier air flow FL, and the fiber FB is caused to flow from the fibrillated material MB by the air flow 305 and collected. Can be separated from components other than fiber FB. In this configuration, since the separation air flow 305 intersecting the transport air flow FL can be expected to disentangle the densely packed fibers FB, the fibers FB contained in the defibrated material MB are further separated from components other than the fibers FB. It can be separated reliably. Therefore, the fiber FB having higher whiteness can be taken out of the raw material, and the sheet S can be formed.

  Further, the regenerating unit 102 includes a sorting unit 40 as a sampling unit that takes out the processing raw material including at least the fiber FB from the defibrated material MB transported through the transport unit 31 via the separation unit 300. In addition, the regenerating unit 102 includes a sheet forming unit that processes the deinking raw material MC, which is the processing raw material collected by the sorting unit 40, into a sheet. The sheet forming unit includes at least a second web forming unit 70 and a sheet forming unit 80, and may include a cutting unit 90. The sheet forming unit may also include a mixing unit 50 and an additive supply unit 52. In addition, the first web forming unit 45 may be configured to extract the processing raw material attached to the mesh by the suction unit 48 sucking the defibrated material MB through the mesh belt 46 (mesh).

  According to this configuration, it is possible to take out the processing raw material from the defibrated material MB including the fibers FB separated from the components other than the fibers FB by the separation unit 300 and process it into a sheet. Furthermore, since the raw material for processing is collected by suctioning the defibrated material MB through the mesh belt 46, the fiber FB contained in the defibrated material MB passed through the separation unit 300 is smaller in size than the component FB, It can be separated more reliably. Therefore, a high quality sheet S can be obtained using a processing material having higher whiteness.

[2. Second embodiment]
Subsequently, a second embodiment to which the present invention is applied will be described.
FIG. 5 is a longitudinal sectional view of the processing unit 30A of the second embodiment. In the second embodiment described below, the same components as those in the first embodiment are given the same reference numerals, and the description thereof is omitted.

  The processing unit 30A is provided in the sheet manufacturing apparatus 100, instead of the processing unit 30 described in the first embodiment. Similarly to the processing unit 30, the processing unit 30A (fiber processing apparatus) includes the conveyance pipe 31, and the conveyance pipe 31 is provided with the separation unit 300A (separation unit).

  The separation unit 300 </ b> A includes a nozzle head 301, an outer pipe 310, walls 312 and 313, and an exhaust duct 320. Further, the transport pipe 31 is provided with a mesh plate 31C having an opening 31D. These configurations are common to the first embodiment.

  In the separation unit 300A, the nozzle head 301 is installed obliquely to the outer pipe 310. For this reason, the direction of the air flow 305 which the nozzle head 301 blows from the nozzle row 304 is not a direction orthogonal to the virtual axis AX, but has an inclination not 90 degrees with respect to the virtual axis AX, and a direction intersecting the virtual axis AX Become. More specifically, the air flow 305 in the separation unit 300A intersects the virtual axis AX and is inclined so as to face the upstream side of the transport air flow FL.

  In FIG. 5, the air flow center 305A of the separation unit 300A is shown by an imaginary line. The air flow center 305A is inclined with respect to the virtual axis AX, and the direction of the air flow 305 faces the upstream side of the transport air flow FL and the mesh plate 31C side. For example, the air flow center 305A of the air flow 305 is angled with respect to an axis perpendicular to the virtual axis AX (more specifically, an axis included in the same plane as the air flow center 305A and perpendicular to the virtual axis AX) In the configuration having an inclination of θ3, the angle θ3 is more than 0 degrees and less than 90 degrees.

  In such a configuration, the position at which the air flow 305 reaches the mesh plate 31C is a position deviated from the nozzle row 304 in the transport air flow FL. In FIG. 5, the center position of the mesh plate 31C in the direction along the transport air flow FL (that is, the virtual axis AX) is shown as a position P1, and the position of the nozzle row 304 is shown as a position P2.

  In the first embodiment, the center position of the mesh plate 31C in the direction along the virtual axis AX substantially coincides with the position of the nozzle row 304. Such a configuration is advantageous because the area in which the blowout area 306 and the mesh plate 31C overlap is large, and the efficiency of separating the fiber FB and the particle PA by the opening 31D is enhanced.

  In the second embodiment, since the air flow 305 is inclined with respect to the virtual axis AX, the position P2 is at a position offset from the position P1 corresponding to the inclination. That is, the position P2 of the nozzle row 304 is on the downstream side of the transport air flow FL from the position P1 of the mesh plate 31C. The offset amount W at the position P2 corresponds to the inclination of the nozzle head 301 (angle θ3 in the figure). In this case, the blowing range 306 is preferably included in the mesh plate 31C. In other words, the offset amount W is determined such that the overlapping area of the blowing range 306 and the mesh plate 31C is maximized. desirable.

  According to the processing unit 30A of the second embodiment, the same effect as that of the processing unit 30 of the first embodiment described above can be obtained. Furthermore, in the processing unit 30A, the air flow 305 flows in a direction inclined with respect to the transport air flow FL, and flows toward the upstream side of the transport air flow FL. Therefore, the internal space of the transfer pipe 31 is more vigorously stirred by the air flow 305. Further, the air flow 305 collides with a stronger force to the fibers FB, the particles PA, and the composite CP transported by the transportation air flow FL. For this reason, since the air flow 305 has a stronger effect of loosening the complex CP, it can be expected that the effect of removing components other than the fiber FB from the defibrated material MB is further enhanced.

[3. Third embodiment]
Subsequently, a third embodiment to which the present invention is applied will be described.
FIG. 6 is a longitudinal sectional view of the processing unit 30B of the third embodiment. In the third embodiment described below, the same components as those in the first embodiment are given the same reference numerals, and the description thereof is omitted.

  The processing unit 30B is provided in the sheet manufacturing apparatus 100 instead of the processing unit 30 described in the first embodiment. The processing unit 30 </ b> B (fiber processing apparatus) includes a transport pipe 32 and a separation unit 300 </ b> B (separation section) provided in the transport pipe 32.

  The conveying pipe 32 (conveying path) is a pipe connected to the pipe 3 and the pipe 4 in the same manner as the conveying pipe 31, and the disaggregated material MB is supplied from the pipe 3 by the conveying air flow FL. The transfer pipe 32 is a bent pipe while the transfer pipe 31 is a straight pipe in the first embodiment. That is, the processing unit 30B is provided at a position where the transport pipe 32, which is a pipe for transporting the defibrated material MB, is bent.

  In the transport air flow FL, the upstream end 32 </ b> A located on the upstream side of the transport pipe 32 is connected to the pipe 3. Further, the downstream end 32 </ b> B on the downstream side of the transport pipe 32 is connected to the pipe 4. Similar to the first embodiment, the defibrated material MB is supplied from the pipe 3 by the carrier air flow FL, and the deinking material MC from which the particles PA are separated by the separation unit 300B is supplied to the pipe 4.

  The transfer pipe 32 includes a mesh plate 32C. The mesh plate 32C has an opening 32D. The configurations of the mesh plate 32C and the opening 32D are the same as the mesh plate 31C and the opening 31D, except that the transfer pipe 32 is a curved pipe.

  That is, the mesh plate 32C (collection part, mesh part) has an opening 32D and functions as a sieve that separates the components of the defibrated material MB according to the size. The mesh plate 32C may be, for example, a wire mesh, an expanded metal obtained by extending a metal plate with a cut, or a punching metal in which holes are formed in a metal plate by a press machine or the like. Further, the size of the opening 32D is arbitrary, but can be, for example, about 0.1 mm. Further, the shape of the opening 32D is arbitrary, and may be an opening formed as a gap between a plurality of wires or an opening formed in a flat plate like a punching metal. The shape of the opening 32D may be polygonal, circular or elliptical. The size of the opening 32D described above can be defined as the opening width of the longest portion in the opening 32D. The shape of the mesh plate 32C is also arbitrary, and may be rectangular, circular, elliptical, various geometric shapes, or shapes having no symmetry.

  In the separation unit 300B, the configurations of the outer pipe 310, the discharge duct 320, and the nozzle head 301 provided in the outer pipe 310 are the same as those of the separation unit 300 of the first embodiment. The air flow 305 blown out by the nozzle array 304 flows in the curved pipe portion of the transfer pipe 32, but if the blow out area 306 of the air flow 305 overlaps the mesh plate 32C provided in the transfer pipe 32, the other configuration is the same. It can be done.

According to the processing unit 30A according to the third embodiment shown in FIG. 6, the particles PA contained in the defibrated material MB are discharged through the opening 32D by the discharge duct 320 as in the first embodiment described above. The fiber FB can be collected by the mesh plate 32C. Therefore, the same effect as the first embodiment can be expected.
Furthermore, the transport pipe 32 is a pipe through which the transport air flow FL flows, and the separation unit 300B supplies the air flow 305 to the bent portion of the transport pipe 32. According to this configuration, it is possible to efficiently take out the fibers from the defibrated material MB conveyed in the bent portion of the conveyance pipe 32. For example, in the sheet manufacturing apparatus 100, when the space for providing the processing unit 30B is limited, the processing unit 30B can be disposed in the curved pipe portion by applying the configuration of FIG. Therefore, the processing unit 30B is provided so as not to hinder the miniaturization of the sheet manufacturing apparatus 100, and the defibrillator MB can be deinked efficiently by the separation unit 300B.

[4. Fourth embodiment]
Subsequently, a fourth embodiment to which the present invention is applied will be described.
FIG. 7 is a perspective view of the processing unit 30C of the fourth embodiment, and FIG. 8 is a longitudinal sectional view of the processing unit 30C. In the fourth embodiment described below, the same components as those in the first embodiment are given the same reference numerals, and the description thereof is omitted.

  The processing unit 30C is provided in the sheet manufacturing apparatus 100, instead of the processing unit 30 described in the first embodiment. The processing unit 30 </ b> C (fiber processing apparatus) includes a transport pipe 33 and two separation units 300 (separation sections) provided in the transport pipe 33. The configuration of each separation unit 300 is common to the configuration described in the first embodiment.

  The transport pipe 33 (transport path) is a pipe connected to the pipe 3 and the pipe 4 similarly to the transport pipe 31 and passing the defibrated material MB transported from the pipe 3 by the transport air flow FL. The upstream end 33 </ b> A of the transport air flow FL of the transport pipe 33 is connected to the pipe 3. Further, the downstream end 33 </ b> B on the downstream side of the transport air flow FL of the transport pipe 33 is connected to the pipe 4.

  The transfer pipe 33 has a mesh plate 33C having an opening 33D. In FIG. 8, a virtual axis located at the center of the transfer pipe 33 is shown by a virtual line in the figure. The virtual axis AX is parallel to the flow direction of the carrier air flow FL in the carrier tube 33.

  The transport pipe 33 is provided on the two mesh plates 33C and 33E. The mesh plate 33C is positioned upstream of the mesh plate 33E in the transport air flow FL. That is, the transport pipe 33 includes a plurality of mesh plates 33C and 33E arranged along the transport air flow FL. The mesh plates 33C and 33E are mesh portions configured in the same manner as the mesh plate 31C, and have openings 33D and 33F. The openings 33D, 33F are openings through which the particles PA contained in the defibrated material MB can pass, and are shaped and sized so as not to pass the fibers FB.

  In the transport pipe 33, the separation unit 300 is disposed at a position corresponding to the mesh plate 33C and a position corresponding to the mesh plate 33E. The configuration of the separation unit 300 is the same as the configuration described in the first embodiment, and includes the nozzle head 301, the outer pipe 310, the discharge duct 320, and the nozzle row 304. Further, the discharge ducts 320 provided in the two separation units 300 are connected to the pipe 5 respectively. Here, the exhaust duct 320 provided in the two separation units 300 may be joined to one pipe (not shown), and this pipe may be connected to the pipe 5. Also, the compressed gas supply pipe 302 provided in each separation unit 300 is connected to the compressed gas supply unit 220 (FIG. 1).

In the processing unit 30C, the air flow 305 is blown from the nozzle array 304 to the defibrated material MB transported from the tube 3 by the transport air flow FL, thereby disentangling the complex CP contained in the deflocculated material MB and meshing the particles PA. The plates 33C and 33E are discharged to the space 311. The particles PA discharged into the space 311 are discharged from the discharge duct 320 into the pipe 5.
Therefore, with respect to the defibrated material MB passing through the transport pipe 33, each of the two separation units 300 performs a process of decomposing the complex CP by the air flow 305 to separate the particles PA. For this reason, since the separation processing is performed in two steps with respect to the separation unit 300, the deinking raw material MC sent to the pipe 4 through the processing unit 30C contains the fiber FB with high purity, and the whiteness is higher. Can be expected.

  As described above, since the processing unit 30C includes the plurality of separation units 300 arranged in the direction of the carrier air flow FL in the carrier tube 33 for transporting the fibrillated material MB, the fiber FB contained in the fibrillated material MB is Can be separated more reliably from components other than fibers.

[5. Fifth embodiment]
FIG. 9 is a longitudinal sectional view of the separating portion of the fifth embodiment. In the fifth embodiment described below, the same reference numerals are given to configurations common to the first to fourth embodiments and the description will be omitted.

  The processing unit 30D is provided in the sheet manufacturing apparatus 100, instead of the processing unit 30 described in the first embodiment. The processing unit 30D (fiber processing apparatus) includes a conveyance pipe 33, and two separation units 300 (separation parts) provided on the conveyance pipe 33, and 300A. The configuration of the separation unit 300 is the same as the configuration described in the first embodiment. The configuration of the separation unit 300A is the same as the configuration described in the second embodiment with reference to FIG.

  In the transport pipe 33 (transport path), two mesh plates 33C and 33E are provided along the transport air flow FL, as in the configuration described in the fourth embodiment. The processing unit 30D includes the separation unit 300 at a position corresponding to the mesh plate 33C, and includes the separation unit 300A at a position corresponding to the mesh plate 33E.

  In the processing unit 30D, the separation unit 300 sprays the air flow 305 in the direction orthogonal to the virtual axis AX, separates the composite CP from the fibrillated material MB, and discharges it from the mesh plate 33C. Further, the separation unit 300A has an inclination of an angle θ3 with respect to the virtual axis AX, and blows the air flow 305 toward the upstream side of the transport air flow FL onto the disaggregated material MB to separate the particles PA from the disintegrated material MB, Eject from the mesh plate 33E.

  In this configuration, in addition to the effects of the separation unit 300 and the separation unit 300A, it is possible to expect the effect of the processing unit 30D to separate the particles PA from the defibrated material MB with a plurality of separation units 300, 300A. That is, the same effect as the configuration described in the fourth embodiment can be obtained.

  Furthermore, in the processing unit 30D, since the plurality of separation units 300 and 300A supply the air flow 305 for separation in different directions, respectively, the defibrillation products MB transported via the separation units 300 and 300A are different. The air flow 305 in the direction is blown. For this reason, the fiber FB can be separated from components other than the fiber FB more effectively by applying force to the complex CP and the particles PA contained in the defibrated material MB from many directions.

[6. Sixth embodiment]
FIG. 10 is a perspective view of a processing unit 30E of the sixth embodiment, and FIG. 11 is a cross-sectional view of the processing unit 30E of the sixth embodiment. In the sixth embodiment described below, the same components as those in the first to fourth embodiments are given the same reference numerals, and the description thereof will be omitted.

  Similarly to the processing unit 30C (FIGS. 7 and 8), the processing unit 30E (fiber processing apparatus) is configured by providing the transport pipe 33 with a plurality of separation units 300. The two separation units 300 included in the processing unit 30E are arranged in directions rotated relative to each other in a plane perpendicular to the virtual axis AX.

  FIG. 6 is a cross-sectional view in a cross section perpendicular to the virtual axis AX, where A indicates a cross-sectional view of the separation unit 300 located upstream of the carrier air flow FL, and B indicates a position downstream of the carrier air flow FL 6 shows a cross-sectional view of the separation unit 300.

  The cross section shown by A in FIG. 6 and the cross section shown by B in FIG. 6 are parallel to each other, and are shown at positions where they are not rotated with respect to the virtual axis AX. That is, the separation units 300, 300 included in the processing unit 30E are relatively rotated around the virtual axis AX. The mesh plates 33C and 33E provided in the transfer pipe 33 are offset from each other about the imaginary axis AX.

  Therefore, the airflows 305 of the two separation units 300 included in the processing unit 30E are blown from different directions to the defibrated material MB transported by the transport airflow FL.

  In this configuration, by providing a plurality of separation units 300, the effect of being able to effectively separate the particles PA from the fibers FB of the defibrated material MB can be obtained, as in the configuration described in the fourth embodiment.

  Furthermore, in the processing unit 30E, since the plurality of separation units 300 and 300 supply the air flow 305 for separation in different directions, respectively, the defibrillator MB is different with respect to the disaggregated material MB transported via the separation units 300 and 300. The air flow 305 in the direction is blown. For this reason, the fiber FB can be separated from components other than the fiber FB more effectively by applying force to the complex CP and the particles PA contained in the defibrated material MB from many directions.

[7. Seventh embodiment]
FIG. 12 is a view showing the overall schematic configuration of a sheet manufacturing apparatus 100A of the seventh embodiment.
The sheet manufacturing apparatus 100A shown in FIG. 12 is configured to transport the deinking raw material MC processed in the processing unit 30 from the defibrating unit blower 26 to the pipe 54 in the sheet manufacturing apparatus 100 (FIG. 1) . Compared to the sheet manufacturing apparatus 100, the sheet manufacturing apparatus 100A does not include the sorting unit 40, the first web forming unit 45, and the rotating body 49.

  In this configuration, the deinked raw material MC processed by the processing unit 30 is conveyed to the mixing unit 50 through the pipe 54, and the additive is supplied from the additive supply unit 52 to the deinked raw material MC. Then, the deinking material MC and the additive are mixed by the mixing unit 50, and the mixture is formed by the second web forming unit 70 into the second web W2. The subsequent steps are as described above.

According to the sheet manufacturing apparatus 100A, the processing unit 30 separates the dust MD, which is a component not used for manufacturing the sheet S, from the defibrated material MB obtained by disintegrating the raw material MA. Since this process does not use the sorting unit 40 and the first web forming unit 45, it is more space saving and the time required for processing is short. For this reason, the sheet S can be manufactured in a shorter time, and the sheet manufacturing apparatus 100A has an advantage of being easy to miniaturize.
Further, according to the sheet manufacturing apparatus 100A, the same effect as the sheet manufacturing apparatus 100 of the first embodiment can be obtained.

  Here, in place of the processing unit 30, it is of course possible to use the processing units 30A, 30B, 30C, 30D, 30E and the like of the above-described respective embodiments.
