[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a storage device and a fiber structure manufacturing device of the present invention will be described in detail based on preferred embodiments shown in the accompanying drawings.

[0011] In Figures 2, 3 and 4, an x-axis, a y-axis and a z-axis that are orthogonal to each other are shown. Hereinafter, the upper side (+z-axis side) of Figures 1, 2, 3 and 4 may be referred to as "upper" or "upper side", and the lower side (-z-axis side) of Figures 1, 2, 3 and 4 may be referred to as "lower" or "lower". Also, Figure 1 is a schematic diagram, and the positional relationship, orientation, size, etc. of each part of the fiber structure manufacturing apparatus 100 are not limited to those shown in the figure.

[0012] In addition, in Fig. 1, the direction in which the coarse fragments M2, the defibrated material M3, the first sorted material M4-1, the second sorted material M4-2, the first web M5, the finely divided bodies M6, the mixture M7, the second web M8, and the sheet S are transported, i.e., the direction indicated by the arrow, is also referred to as the transport direction. The tip side of the arrow in Fig. 1 is also referred to as the "downstream side" in the transport direction, and the base side of the arrow in Fig. 1 is also referred to as the "upstream side" in the transport direction.

[0013] The fiber structure manufacturing apparatus 100 shown in FIG. 1 is an apparatus for manufacturing a fiber structure that manufactures a sheet S, which is an example of a fiber structure, from a raw material M1, which is waste paper such as used copy paper.

[0014] The fiber structure manufactured by the fiber structure manufacturing apparatus 100 is not limited to the sheet S, and may be, for example, a block shape, a cup shape, a rod shape, a cylinder shape, a ring shape, a frame shape, or other irregular shapes. The shape and structure of the fiber structure depend on the configuration of the molding unit 20 described later, etc.

[0015] As shown in FIG. 1, the fiber structure manufacturing apparatus 100 includes a raw material supply section 11, a coarse crushing section 12, a defibrating section 13, a sorting section 14, a first web forming section 15, a fine dividing section 16, a mixing section 17, a dispersion section 18, a second web forming section 19, a molding section 20, a cutting section 21, a stock section 22, a powder collecting device 3, a compressor 4, and a storage device 5.

[0016] The fiber structure manufacturing apparatus 100 also includes a humidifier section 231, a humidifier section 232, a humidifier section 233, a humidifier section 234, a humidifier section 235, and a humidifier section 236. In addition, the fiber structure manufacturing apparatus 100 also includes a blower 261, a blower 262, and a blower 263.

[0017] In addition, in the fiber structure manufacturing apparatus 100, a raw material supplying process, a coarse crushing process, a defibrating process, a sorting process, a first web forming process, a dividing process, a mixing process, a loosening process, a second web forming process, a sheet forming process, and a cutting process are carried out in this order. In addition, a powder collecting process is carried out so as to overlap with these processes in time.

[0018] The configuration of each part will be described below. The raw material supplying section 11 is a section that performs a raw material supplying step of supplying the raw material M1 to the crushing section 12. The raw material M1 is a sheet-like material made of a fiber-containing material including cellulose fibers. The cellulose fibers may be fibrous and contain cellulose as a compound as the main component, and may contain hemicellulose and lignin in addition to cellulose. The raw material M1 may be in any form, such as woven fabric or nonwoven fabric. The raw material M1 may be, for example, recycled paper produced by disintegrating waste paper and regenerating it, or synthetic paper such as Yupo paper (registered trademark), or it may not be recycled paper.

[0019] The crushing unit 12 is a section that performs a crushing step of crushing the raw material M1 supplied from the raw material supply unit 11 in air such as the atmosphere. The crushing unit 12 has a pair of crushing blades 121 and a chute 122.

[0020] The pair of crushing blades 121 rotate in opposite directions to each other, and can crush the raw material M1 between them, that is, cut it into crushed pieces M2. The shape and size of the crushed pieces M2 are preferably suitable for defibration processing in the defibration unit 13. Examples of the shape of the crushed pieces M2 include small pieces with a square planar shape, rectangular pieces, and particularly small pieces with a strip shape. The size of the crushed pieces M2 is preferably small pieces with an average side length of 100 mm or less, and more preferably small pieces with an average side length of 3 mm or more and 70 mm or less. The shape of the small pieces may be other than square or rectangular. The thickness is preferably 0.07 mm or more and 0.10 mm or less.

[0021] The chute 122 is disposed below the pair of crushing blades 121 and has, for example, a cone or funnel shape. This allows the chute 122 to receive the coarsely crushed pieces M2 that have been crushed by the crushing blades 121 and dropped.

[0022] Moreover, above the chute 122, a humidifying section 231 is disposed adjacent to the pair of coarse crushing blades 121. The humidifying section 231 humidifies the coarsely crushed pieces M2 in the chute 122. This humidifying section 231 is configured as an evaporation type humidifier that has a moisture-containing filter (not shown) and supplies humidified air with increased humidity to the coarsely crushed pieces M2 by passing air through the filter. By supplying the humidified air to the coarsely crushed pieces M2, it is possible to suppress adhesion of the coarsely crushed pieces M2 to the chute 122 and the like due to electrostatic forces.

[0023] The chute 122 is connected to the defibrating unit 13. The coarse fragments M2 collected by the chute 122 are sent to the defibrating unit 13.

[0024] The defibrating unit 13 is a section that performs a defibrating process in which the coarsely crushed pieces M2 are defibrated in the air, i.e., in a dry manner. The defibrating process in this defibrating unit 13 makes it possible to generate a defibrated material M3 from the coarsely crushed pieces M2. Here, "defibrating" refers to untangling the coarsely crushed pieces M2, which are made up of multiple fibers bound together, into individual fibers. This untangled material becomes the defibrated material M3. The shape of the defibrated material M3 is linear or band-like. The defibrated material M3 may also be present in a state where it is entangled with other pieces to form a mass, that is, in a state where it forms so-called "lumps."

[0025] In addition, the defibrating unit 13 can generate an air flow toward the sorting unit 14, i.e., an airflow, by the rotation of a rotor (not shown). This allows the coarse fragments M2 to be introduced from the pipe 241 to the upstream side of the defibrating unit 13, and after defibration processing, the defibrated material M3 can be sent to the sorting unit 14 via the pipe 242.

[0026] A pipe 242 is connected to the downstream side of the defibrating unit 13. A blower 261 consisting of, for example, a turbo fan is installed midway through the pipe 242. The blower 261 is an airflow generating device that generates an airflow toward the sorting unit 14. This promotes the introduction of the coarsely crushed pieces M2 into the defibrating unit 13 and the sending out of the defibrated material M3 to the sorting unit 14. Due to its structure, the defibrating unit 13 smoothly passes through and is defibrated, and the operation of the blower 261 installed downstream of the defibrating unit 13 promotes the passage of the coarsely crushed pieces M2 within the defibrating unit 13 and the defibrating process. The blower 261 may be installed upstream of the defibrating unit 13.

[0027] The sorting unit 14 is a section that performs a sorting process in which the defibrated material M3 is sorted according to the fiber length. In the sorting unit 14, the defibrated material M3 is sorted into a first sorted material M4-1 and a second sorted material M4-2 having a fiber length longer than that of the first sorted material M4-1. The first sorted material M4-1 has a size suitable for the subsequent production of the sheet S. On the other hand, the second sorted material M4-2 includes, for example, material that is insufficiently defibrated or material in which defibrated fibers are excessively aggregated.

[0028] The sorting section 14 has a drum 141 and a housing section 142 that houses the drum 141.

[0029] The drum 141 is a sieve composed of a cylindrical mesh body and rotates around its central axis. The defibrated material M3 flows into this drum 141. Then, as the drum 141 rotates, the defibrated material M3 smaller than the mesh opening is sorted as the first sorted material M4-1, and the defibrated material M3 larger than the mesh opening is sorted as the second sorted material M4-2.

[0030] The first sorted item M4-1 falls from the drum 141. Meanwhile, the second sorted material M4-2 is sent to a pipe 243 connected to the drum 141. The end of the pipe 243 opposite the drum 141, i.e., the downstream end, is connected midway through the pipe 241. The second sorted material M4-2 that passes through this pipe 243 merges with the coarsely crushed pieces M2 inside the pipe 241 and flows into the defibrating section 13 together with the coarsely crushed pieces M2. As a result, the second sorted material M4-2 is returned to the defibrating section 13 and is defibrated together with the coarsely crushed pieces M2.

[0031] The first selected object M4-1 that has fallen from the drum 141 falls while being dispersed in the air, and heads toward the first web forming unit 15 located below the drum 141. The first web forming unit 15 is a section that carries out a first web forming step of forming a first web M5 from the first selected object M4-1. The first web forming unit 15 has a mesh belt 151, three tension rollers 152, and a suction unit 153.

[0032] The mesh belt 151 is an endless belt on which the first sorted material M4-1 is accumulated. The mesh belt 151 is wound around three tension rollers 152. As the tension rollers 152 rotate, the first sorted material M4-1 on the mesh belt 151 is transported downstream.

[0033] The size of the first sorted material M4-1 is equal to or larger than the mesh size of the mesh belt 151. This restricts the passage of the first sorted material M4-1 through the mesh belt 151, and therefore the first sorted material M4-1 can be piled up on the mesh belt 151. Furthermore, the first sorted material M4-1 is transported downstream together with the mesh belt 151 while being piled up on the mesh belt 151, and is formed as a first web M5.

[0034] The first sorted object M4-1 may contain foreign matter such as dust, dirt, paper powder, and broken pieces of fiber. Foreign matter such as dust, dirt, paper powder, and broken pieces of fiber are collectively referred to as waste powder. The waste powder may be generated, for example, by crushing in the crushing section 12 or defibrating in the defibrating section 13. Powder H resulting from such waste powder is separated from the first sorted object M4-1 in the first web forming section 15 and is collected and recovered by the powder collecting device 3 described below. By separating and removing the waste powder from the first sorted object M4-1, the quality of the sheet S to be manufactured can be improved.

[0035] The suction unit 153 is a suction mechanism that sucks air from below the mesh belt 151. This makes it possible to suck the powder H that has passed through the mesh belt 151 together with the air.

[0036] The suction unit 153 is connected to the powder collector 3 via a pipe 245. The powder H, which is waste powder, sucked by the suction unit 153 is collected in the powder collector 3 via the pipe 245.

[0037] A blower 262 is installed in the middle of the pipe 245. By operating the blower 262, a suction force can be generated in the suction section 153. This promotes the formation of the first web M5 on the mesh belt 151. The first web M5 has the powder H removed, improving the quality of the material. In addition, by operating the blower 262, the powder H is transferred through the pipe 245 to the powder collector 3 and collected.

[0038] The housing part 142 is connected to the humidifier part 232. The humidifier part 232 is configured with an evaporative humidifier. This allows humidified air to be supplied into the housing part 142. The first sorted object M4-1 can be humidified by this humidified air, and therefore, the first sorted object M4-1 can be prevented from adhering to the inner wall of the housing part 142 due to electrostatic force.

[0039] A humidifying section 235 is disposed downstream of the sorting section 14. The humidifying section 235 is configured with an ultrasonic humidifier that sprays water. This allows moisture to be supplied to the first web M5, and thus the moisture content of the first web M5 is adjusted. This adjustment makes it possible to suppress adhesion of the first web M5 to the mesh belt 151 due to electrostatic force. As a result, the first web M5 is easily peeled off from the mesh belt 151 at the position where the mesh belt 151 is folded back by the tension roller 152.

[0040] The segmentation unit 16 is disposed downstream of the humidification unit 235. The segmentation unit 16 is a section that performs a segmentation step of segmenting the first web M5 peeled off from the mesh belt 151. The segmentation unit 16 has a rotatably supported propeller 161 and a housing portion 162 that houses the propeller 161. The rotating propeller 161 can segment the first web M5. The segmented first web M5 becomes segmented bodies M6. The segmented bodies M6 move down inside the housing portion 162.

[0041] The housing part 162 is connected to the humidifier part 233. The humidifier part 233 is configured by an evaporation type humidifier. This allows humidified air to be supplied into the housing part 162. This humidified air can also prevent the fragmented bodies M6 from adhering to the propeller 161 and the inner wall of the housing part 162 due to electrostatic force.

[0042] A mixing section 17 is disposed downstream of the subdivision section 16. The mixing section 17 is a section in which a mixing step is performed to mix the subdivision bodies M6 with an additive. The mixing section 17 has an additive supply section 171, a pipe 172, and a blower 173.

[0043] The pipe 172 connects the housing portion 162 of the subdivision portion 16 and the housing 182 of the dispersion portion 18, and is a flow path through which the mixture M7 of the subdivision bodies M6 and the additive passes.

[0044] An additive supply unit 171 is connected to the middle of the pipe 172. The additive supply unit 171 has a housing portion 170 in which an additive is accommodated, and a screw feeder 174 provided in the housing portion 170. By rotation of the screw feeder 174, the additive in the housing portion 170 is pushed out from the housing portion 170 and supplied into the pipe 172. The additive supplied into the pipe 172 is mixed with the fragmented bodies M6 to become a mixture M7.

[0045] Here, examples of additives supplied from the additive supply unit 171 include a binder that bonds fibers together, a colorant for coloring fibers, an aggregation inhibitor for inhibiting aggregation of fibers, a flame retardant for making fibers less flammable, a paper strength enhancer for enhancing the paper strength of the sheet S, and the like, and one or more of these can be used in combination. In the following, as an example, a case where the additive is a binder P1 will be described. By including the binder P1 that bonds fibers together in the additive, the strength of the sheet S can be increased.

[0046] Examples of the binder P1 include natural product-derived components such as starch, dextrin, glycogen, amylose, hyaluronic acid, kudzu, konjac, potato starch, etherified starch, esterified starch, natural gum paste, fiber-derived paste, seaweed, and animal protein, as well as polyvinyl alcohol, polyacrylic acid, and polyacrylamide, and one or more selected from these can be used in combination, but natural product-derived components are preferred, and starch is more preferred. In addition, various polyolefins, acrylic resins, thermoplastic resins such as polyvinyl chloride, polyester, and polyamide, and various thermoplastic elastomers can also be used.

[0047] A blower 173 is installed in the pipe 172 downstream of the additive supply unit 171. The action of a rotating part such as a blade of the blower 173 promotes mixing of the fragmented bodies M6 and the binder P1. The blower 173 can generate an airflow toward the dispersion unit 18. This airflow can agitate the fragmented bodies M6 and the binder P1 in the pipe 172. As a result, the mixture M7 is transported to the dispersion unit 18 in a state in which the fragmented bodies M6 and the binder P1 are uniformly dispersed. The fragmented bodies M6 in the mixture M7 are loosened in the process of passing through the pipe 172, becoming finer fibrous.

[0048] The blower 173 is electrically connected to the control device 28, and the operation thereof is controlled by the control device 28. By adjusting the airflow rate of the blower 173, the amount of air sent into the drum 181 can be adjusted.

[0049] Although not shown in the figure, the end of pipe 172 on the drum 181 side is branched into two, and the branched ends are each connected to an inlet port (not shown) formed on the end face of drum 181.

[0050] 1 is a section that performs a disintegration process for disintegrating and releasing entangled fibers in the mixture M7. The dispersion section 18 has a drum 181 that introduces and releases the defibrated mixture M7, and a housing 182 that houses the drum 181.

[0051] The drum 181 is a sieve that is composed of a cylindrical mesh body and rotates around its central axis. As the drum 181 rotates, fibers and the like of the mixture M7 that are smaller than the mesh openings can pass through the drum 181. At that time, the mixture M7 is loosened and discharged together with air. That is, the drum 181 functions as a discharge section that discharges the material including fibers.

[0052] The drum 181 is connected to a drive source (not shown) and rotates by a torque output from the drive source. The drive source is electrically connected to the control device 28, and the operation of the drive source is controlled by the control device 28.

[0053] Furthermore, the housing 182 is connected to the humidifier 234. The humidifier 234 is configured as an evaporative humidifier. This allows humidified air to be supplied into the housing 182. The inside of the housing 182 can be humidified by this humidified air, and therefore, it is also possible to prevent the mixture M7 from adhering to the inner wall of the housing 182 due to electrostatic force.

[0054] Furthermore, the mixture M7 discharged from the drum 181 falls while being dispersed in the air, and heads toward the second web forming unit 19 located below the drum 181. The second web forming unit 19 is a section where a second web forming step is carried out in which the mixture M7 is deposited to form a second web M8, which is a deposit. The second web forming unit 19 has a mesh belt 191, a tension roller 192, and a suction unit 193.

[0055] The mesh belt 191 is a mesh member, and in the illustrated configuration, is configured as an endless belt. The mixture M7 dispersed and discharged by the dispersion unit 18 is accumulated on the mesh belt 191. The mesh belt 191 is wound around four tension rollers 192. The mixture M7 on the mesh belt 191 is transported downstream by the rotational drive of the tension rollers 192.

[0056] In the illustrated configuration, the mesh belt 191 is used as an example of the mesh member, but the present invention is not limited to this, and the mesh member may be, for example, a flat plate-like member.

[0057] Moreover, most of the mixture M7 on the mesh belt 191 has a size equal to or larger than the mesh openings of the mesh belt 191. This prevents the mixture M7 from passing through the mesh belt 191, and therefore the mixture M7 can be accumulated on the mesh belt 191. Moreover, while being accumulated on the mesh belt 191, the mixture M7 is transported downstream together with the mesh belt 191, and is formed as a second web M8.

[0058] The mixture M7 may contain foreign matter, such as dust, dirt, paper powder, and cut pieces of fibers, that is, waste powder. The waste powder may be generated by stirring, mixing, loosening, and the like in the subdivision section 16, the mixing section 17, and the dispersion section 18. In addition, waste powder that has not been completely removed from the first sorted material M4-1 in the first web forming section 15 may remain in the mixture M7. Such powder H due to waste powder is separated from the mixture M7 in the second web forming section 19 and is collected and recovered by the powder collecting device 3 described below. By separating and removing the waste powder from the mixture M7, the quality of the sheet S to be manufactured can be improved.

[0059] The suction unit 193 is a suction mechanism that sucks air from below the mesh belt 191. This allows the mixture M7 to be sucked onto the mesh belt 191, thereby facilitating the accumulation of the mixture M7 on the mesh belt 191.

[0060] The suction unit 193 is connected to the powder collector 3 via a pipe 246. The powder H, which is waste powder, sucked by the suction unit 193 is collected in the powder collector 3 via the pipe 246.

[0061] A blower 263 is installed in the middle of the pipe 246. By operating this blower 263, a suction force can be generated in the suction section 193. This promotes the formation of the second web M8 on the mesh belt 191. This second web M8 has the powder H removed, improving the quality of the material. In addition, by operating the blower 263, the powder H is transferred through the pipe 246 to the powder collector 3 and collected.

[0062] 1, powder collector 3 is a device that collects powder H (waste powder) sucked by suction unit 153 and suction unit 193, and includes housing 31 and filter 32 installed in housing 31. Tubes 245 and 246 are connected to housing 31, and powder H is introduced into housing 31 via tubes 245 and 246 and collected by filter 32.

[0063] A humidifying section 236 is disposed downstream of the dispersion section 18. The humidifying section 236 is configured with an ultrasonic humidifier similar to the humidifying section 235. This allows moisture to be supplied to the second web M8, and thus the moisture content of the second web M8 is adjusted. This adjustment makes it possible to suppress adhesion of the second web M8 to the mesh belt 191 due to electrostatic force. This allows the second web M8 to be easily peeled off from the mesh belt 191 at the position where the mesh belt 191 is folded back by the tension roller 192.

[0064] The total amount of moisture added from the humidifying units 231 to 236 is preferably, for example, 0.5 parts by mass to 20 parts by mass with respect to 100 parts by mass of the material before humidification.

[0065] A forming unit 20 is disposed downstream of the second web forming unit 19. The forming unit 20 is a section where a sheet forming process is performed to form a sheet S, which is a fiber structure, from the second web M8. The forming unit 20 has a pressurizing unit 201 and a heating unit 202.

[0066] The pressurizing unit 201 has a pair of calender rollers 203, and can pressurize the second web M8 between the calender rollers 203 without heating it. This increases the density of the second web M8. When heating, the degree of heating is preferably such that the binder P1 is not melted. Then, the second web M8 is transported toward the heating unit 202. One of the pair of calender rollers 203 is a driven roller driven by the operation of a motor (not shown), and the other is a driven roller.

[0067] The heating section 202 has a pair of heating rollers 204, and can apply pressure to the second web M8 while heating it between the heating rollers 204. This heating and pressurization melts the binder P1 in the second web M8, and the fibers are bound to each other via the molten binder P1. This forms a sheet S. Then, this sheet S is transported toward the cutting section 21. Note that one of the pair of heating rollers 204 is a driven roller driven by the operation of a motor (not shown), and the other is a driven roller.

[0068] The cutting unit 21 is disposed downstream of the forming unit 20. The cutting unit 21 is a portion that performs a cutting step of cutting the sheet S. The cutting unit 21 has a first cutter 211 and a second cutter 212.

[0069] The first cutter 211 cuts the sheet S in a direction intersecting the conveying direction of the sheet S, particularly in a direction perpendicular to the conveying direction.

[0070] The second cutter 212 is disposed downstream of the first cutter 211 and cuts the sheet S in a direction parallel to the conveying direction of the sheet S. This cutting is performed to remove unnecessary portions on both side edges of the sheet S in the width direction, thereby adjusting the width of the sheet S.

[0071] A sheet S having a desired shape and size is obtained by such cutting by the first cutter 211 and the second cutter 212. Then, this sheet S is conveyed further downstream and accumulated in the stock unit 22.

[0072] Each of the components of the fiber structure manufacturing apparatus 100 is electrically connected to a control device 28. The operation of each of these components is controlled by the control device 28.

[0073] As shown in FIG. 1, the control device 28 includes a control unit 281, a storage unit 282, and a communication unit 283.

[0074] The control unit 281 has at least one processor and executes various programs stored in the storage unit 282. For example, a CPU (Central Processing Unit) can be used as the processor. The control unit 281 also has various functions, such as a function to control the driving of each part of the fiber structure manufacturing apparatus 100 related to sheet manufacturing, such as a function to control the driving of the blower 261.

[0075] The storage unit 282 stores, for example, programs related to sheet manufacturing. The communication unit 283 is composed of, for example, an I / O interface, and communicates with each unit of the fiber structure manufacturing apparatus 100. In addition, the communication unit 283 has a function of communicating with a computer or server (not shown), for example, via a network.

[0076] The control device 28 may be built into the fiber structure manufacturing apparatus 100, or may be provided in an external device such as an external computer. Furthermore, the control unit 281 and the memory unit 282 may, for example, be integrated into one unit, or the control unit 281 may be built into the fiber structure manufacturing apparatus 100 and the memory unit 282 may be provided in an external device such as an external computer, or the memory unit 282 may be built into the fiber structure manufacturing apparatus 100 and the control unit 281 may be provided in an external device such as an external computer.

[0077] 1, the compressor 4 generates compressed air used in the manufacturing process of the sheet S and supplies it to predetermined locations of the fiber structure manufacturing apparatus 100. Specifically, the compressor 4 generates compressed air and supplies the generated compressed air to each of the raw material supply section 11, the coarse crushing section 12, the sorting section 14, the dispersing section 18, the molding section 20, and the cutting section 21.

[0078] The supply conditions, such as the supply timing and supply amount of compressed air, are different for each of the raw material supply section 11, the crushing section 12, the screening section 14, the dispersion section 18, the forming section 20 and the cutting section 21.

[0079] In the raw material supplying section 11, compressed air is intermittently sprayed toward the raw material M1 by an air nozzle (not shown). This allows the raw material supplying section 11 to peel off overlapping raw material M1 and supply it sheet by sheet.

[0080] In the crushing unit 12, compressed air is intermittently sprayed by an air nozzle (not shown) toward the inner surface of the chute 122. This allows the crushed pieces M2 adhering to the inner surface of the chute 122 to be peeled off and supplied to the defibrating unit 13.

[0081] In the screening unit 14, compressed air is intermittently sprayed by an air nozzle (not shown) toward the inner surface of the drum 141. This causes the defibrated material M3 adhering to the inner surface of the drum 141 to be peeled off and dispersed from the drum 141.

[0082] In the dispersion section 18, compressed air is intermittently sprayed by an air nozzle (not shown) toward the inner surface of the drum 181. This causes the mixture M7 adhering to the inner surface of the drum 181 to be peeled off and dispersed from the drum 181.

[0083] In the forming unit 20, compressed air is intermittently sprayed by an air nozzle (not shown) toward the calender roller 203 and the heating roller 204. This makes it possible to remove paper powder adhering to the calender roller 203 and the heating roller 204.

[0084] In the cutting unit 21, compressed air is intermittently sprayed by an air nozzle (not shown) toward the first cutter 211 and the second cutter 212. This makes it possible to remove paper powder adhering to the first cutter 211 and the second cutter 212.

[0085] The compressor 4 may be a volumetric type such as a reciprocating type or a rotary type, or a turbo type such as an axial flow type or a centrifugal type. Regardless of the type, the compressor 4 generates heat during operation. In order to stably generate compressed air, the compressor 4 needs to be cooled.

[0086] Although the raw material supply section 11, the crushing section 12, the sorting section 14, the dispersion section 18, the shaping section 20, and the cutting section 21 have been given as examples of "predetermined sections" to which the compressor 4 supplies compressed air, the present invention is not limited thereto, and it is sufficient that compressed air is supplied to at least one of these sections. Furthermore, the compressor 4 may be configured to supply compressed air to sections other than the raw material supply section 11, the crushing section 12, the sorting section 14, the dispersion section 18, the shaping section 20, and the cutting section 21.

[0087] As shown in Figures 2 and 3, the storage device 5 has a first storage tool 6 that stores the compressor 4, and a second storage tool 7 that stores the first storage tool 6. The storage device 5 has a function of dissipating heat generated by the operation of the compressor 4. That is, the storage device 5 cools the compressor 4 with the first air A1 that is taken in, and exhausts the second air A2 that has been used for cooling and has been heated. The storage device 5 also has a soundproofing function against noise caused by the operation of the compressor 4.

[0088] The first storage device 6 has a first casing 61 and a first air guide member 62 . The first casing 61 is formed of a rectangular box, and has a first storage section 63, a first intake port 64, and a first exhaust port 65. The first casing 61 also has a top plate 611, a bottom plate 612, and four side walls 613, 614, 615, and 616. The top plate 611, the bottom plate 612, and the four side walls 613, 614, 615, and 616 each have a flat plate shape.

[0089] The top plate 611 and the bottom plate 612 are parallel to the xy plane and face each other in the z-axis direction. The top plate 611 is located on the +z-axis side, and the bottom plate 612 is located on the -z-axis side. The side walls 613 and 614 are parallel to the yz plane and face each other in the x-axis direction. The side walls 613 are first walls and are located on the +x-axis side, and the side walls 614 are located on the -x-axis side. The side walls 615 and 616 are parallel to the xz plane and face each other in the y-axis direction. The side walls 615 are located on the +y-axis side, and the side walls 616 are located on the -y-axis side.

[0090] Such a first casing 61 can be made of various metal materials such as aluminum, stainless steel, copper alloys, and various plastic materials. When the first casing 61 is made of a metal material, there are advantages in that sufficient strength is ensured and that heat dissipation is excellent.

[0091] The first storage section 63 is an internal space that stores the compressor 4. That is, the space surrounded by a top plate 611, a bottom plate 612, and four side walls 613, 614, 615, and 616 constitutes the first storage section 63.

[0092] The first intake port 64 is a circular opening that takes in air to be supplied to the compressor 4. Hereinafter, the air taken into the first storage section 63 from the first intake port 64 will be referred to as the first air A1. In this embodiment, the first air A1 is the atmosphere. The first intake port 64 is provided in the side wall 613. It is provided in the center of the side wall 613 in the y-axis direction and at a position offset toward the -z-axis side from the center in the z-axis direction.

[0093] The first air A1 is taken in through the first intake port 64 and then used to cool the compressor 4. However, without being limited thereto, all or a part of the first air A1 may be used to generate compressed air by the compressor 4 after being taken in through the first intake port 64.

[0094] The first exhaust port 65 is a circular opening that exhausts air (hereinafter referred to as "second air A2") that is hotter than the first air A1.

[0095] The first exhaust port 65 is provided in the side wall 613. The first exhaust port 65 is provided in the center of the side wall 613 in the y-axis direction and in a position shifted toward the +z-axis side from the center in the z-axis direction. That is, the first exhaust port 65 is provided on the +z-axis side of the first intake port 64.

[0096] The second air A2 is air used to cool the compressor 4. In other words, it is air warmed by heat transferred from the compressor 4, and has a higher temperature than the first air A1. The difference in temperature between the second air A2 and the first air A1 is, for example, about 5°C or more and 70°C or less.

[0097] The intake of the first air A1 from the first intake port 64 and the exhaust of the second air A2 are performed by the operation of a blower (not shown) installed in the first storage section 63. That is, the blower forms an airflow that cools the compressor 4 with the first air A1, generates the second air A2 containing the heat of the compressor 4, and exhausts it. Note that such a blower may be installed outside the first casing 61.

[0098] Although not shown, the first casing 61 has a first insertion hole for inserting a pipe for introducing air to be supplied to the compressor 4 and a second insertion hole for inserting a pipe for discharging the compressed air generated by the compressor 4. The first insertion hole and the second insertion hole may be formed in any of the wall portions of the top plate 611, the bottom plate 612, and the four side walls 613, 614, 615, and 616.

[0099] The opening shapes and installation positions of the first intake port 64 and the first exhaust port 65 are not limited to the configuration shown in the figure, and may be of any shape and in any position.

[0100] In this manner, the first casing 61 has the side wall 613 as a flat plate-like first wall portion, and the first intake port 64 and the first exhaust port 65 are provided in the side wall 613. This allows other structures to be placed close to or on the outer surfaces of the walls other than the side wall 613, for example, the top plate 611, the bottom plate 612, and the side walls 614, 615, and 616. This increases the degree of freedom in the layout of the device components, and also allows the device as a whole to be made more compact.

[0101] As shown in FIG. 3, the first air guide member 62 is connected to the first exhaust port 65, and guides the second air A2 discharged from the first exhaust port 65 away from the first intake port 64 and discharges it.

[0102] The first air guide member 62 is composed of a hollow plate-like member extending in the y-axis direction, and has a flow path 620 extending in the y-axis direction inside. This first air guide member 62 functions as a duct that guides the second air A2 discharged from the first exhaust port 65 and discharges it at a desired position.

[0103] An opening 621 is formed in a portion on the -y-axis side of the surface on the -x-axis side of the first air guide member 62. The opening 621 communicates with the flow path 620. The opening 621 is connected to the first exhaust port 65.

[0104] An opening 622 is formed in a portion on the +y-axis side of the surface on the +x-axis side of the first air guide member 62. The opening 622 is in communication with the flow path 620.

[0105] The second air A2 discharged from the first exhaust port 65 is discharged to the outside through the opening 621, the flow path 620, and the opening 622 in this order. The first air guide member 62 allows the second air A2 discharged from the first exhaust port 65 to be guided away from the first intake port 64 and discharged. In this embodiment, the second air A2 discharged from the first exhaust port 65 can be guided away from the first intake port 64 to the +y-axis side and discharged. Therefore, it is possible to prevent or suppress the second air A2 discharged from the first exhaust port 65 from being directly sucked in through the first intake port 64. As a result, the compressor 4 can be well cooled and the compressor 4 can stably generate compressed air.

[0106] As described above, the storage device 5 stores the compressor 4 that supplies compressed air used in the manufacture of the sheet S, which is an example of a fiber structure. The storage device 5 also includes a first storage section 63 that stores the compressor 4, a first casing 61 having a first intake port 64 that takes in the first air A1 supplied to the compressor 4, and a first exhaust port 65 that exhausts the second air A2 that is hotter than the first air A1, and a first storage tool 6 having a first air guide member 62 that is connected to the first exhaust port 65 and guides the second air A2 exhausted from the first exhaust port 65 away from the first intake port 64 and exhausts it. This makes it possible to prevent the second air A2 exhausted from the first exhaust port 65 from being directly sucked in through the first intake port 64. This makes it possible to cool the compressor 4 well, and to stably generate and supply compressed air by the compressor 4.

[0107] The fiber structure manufacturing apparatus 100 also includes a raw material supply section 11 that supplies raw material M1, which is an example of a fiber-containing material, a second web forming section 19 that is a deposition section that deposits defibrated material M3 of the raw material M1 to produce a second web M8 as a deposit, a forming section 20 that molds the second web M8 to produce a sheet S, which is an example of a fiber structure, a compressor 4 that supplies compressed air used in manufacturing the sheet S, and a storage device 5 that stores the compressor 4, and the storage device 5 stores the compressor 4. The storage device 5 also includes a first storage section 63 for storing the compressor 4, a first casing 61 having a first intake port 64 for taking in the first air A1 supplied to the compressor 4, and a first exhaust port 65 for exhausting the second air A2 having a higher temperature than the first air A1, and a first storage tool 6 having a first air guide member 62 connected to the first exhaust port 65 and guiding the second air A2 discharged from the first exhaust port 65 away from the first intake port 64 and discharging it. This makes it possible to prevent the second air A2 discharged from the first exhaust port 65 from being directly drawn in through the first intake port 64. This allows the compressor 4 to be cooled well, and the compressed air to be generated and supplied stably by the compressor 4. As a result, the sheet S can be manufactured more stably and well.

[0108] The first air guide member 62 has an end (one end) on the -y-axis side connected to the first exhaust port 65, and an opening 622 formed at an end (the other end) on the +y-axis side is entirely located outside the side wall 613 in a plan view of the side wall 613 (when viewed from the x-axis direction). This allows the second air A2 discharged from the first exhaust port 65 to be guided and discharged farther away from the first intake port 64. This allows the compressor 4 to be cooled more effectively, and the compressor 4 to generate compressed air more stably.

[0109] In addition, a portion of the opening 622 may be positioned at a position overlapping with the side wall 613 when viewed in a plan view, or the entire opening 622 may be positioned at a position overlapping with the side wall 613 when viewed in a plan view.

[0110] Further, the present invention is not limited to the above configuration, and the direction in which the first air guiding member 62 moves the second air A2 away from the first air inlet 64 may be any direction. For example, a configuration in which the second air A2 is guided and discharged so as to move away from the first air inlet 64 toward the -y axis side, a configuration in which the second air A2 is guided and discharged so as to move away from the first air inlet 64 toward the +z axis side, a configuration in which the second air A2 is guided and discharged so as to move away from the first air inlet 64 toward the -z axis side, a configuration in which the second air A2 is guided and discharged so as to move away from the first air inlet 64 toward the +x axis side, and a configuration in which the second air A2 is guided and discharged so as to move away from the first air inlet 64 toward the -x axis side may be employed. Further, any combination of these configurations may be used.

[0111] Further, the first air guiding member 62 may be capable of adjusting the direction in which the second air A2 is discharged. An example of the conditions under which the functions and effects of the first air guiding member 62 are more significantly exhibited will be described. As shown in FIG. 3, when the center-to-center distance between the first air inlet 64 and the first air outlet 65 is L1, and the center-to-center distance between the first air inlet 64 and the opening 622 is L2, it is sufficient that L1 < L2, preferably L1 / L2 ≤ 0.75, and more preferably 0.02 ≤ L1 / L2 ≤ 0.6.

[0112] As described above, one end portion (the end portion on the -y axis side) of the first air guiding member 62 is connected to the first air outlet 65, and the other end portion (the end portion on the +y axis side) has the opening 622. In the present embodiment, at least a part, and in fact all, of the opening 622 is located outside the side wall 613 in a plan view of the side wall 613 serving as the first wall portion. Thereby, the second air A2 discharged from the first air outlet 65 can be guided and discharged so as to move away from the first air inlet 64. Therefore, the compressor 4 can be cooled better, and the generation and supply of compressed air by the compressor 4 can be performed more stably.

[0113] The first air guide member 62 may be installed so as to be displaceable or changeable in its installation position with respect to the first casing 61. As a first example, the first air guide member 62 can be configured to be expandable and contractible in the y-axis direction, and the position of the opening 622 changes due to this expansion and contraction, resulting in a change in the center-to-center distance L2. As a second example, the first air guide member 62 can be installed so as to be rotatable about a rotation axis parallel to the x-axis passing through the center of the opening 621, and the rotation of the first air guide member 62 changes the position of the opening 622, resulting in a change in the center-to-center distance L2.

[0114] 2, the second storage device 7 has a function of storing the first storage device 6 storing the compressor 4, as well as other parts, devices, wiring, piping, etc. The second storage device 7 also has a soundproofing function against noise caused by the operation of the compressor 4. The storage device 5 can exhibit excellent soundproofing function due to the synergistic effect of the first storage device 6 and the second storage device 7.

[0115] The first storage device 6 is stored in the second storage device 7 such that the surface on the +x-axis side of the first air guide member 62 is in close contact with the inner surface of the side wall 713 of the second storage device 7. However, this is not limited to the configuration, and the first storage device 6 may be stored in the second storage device 7 such that the surface on the +x-axis side of the first air guide member 62 is separated from the inner surface of the side wall 713 of the second storage device 7.

[0116] The second storage device 7 has a second casing 71 and a second air guide member 72. The second casing 71 is formed of a rectangular parallelepiped box, and has a second storage section 73, a second intake port 74, and a second exhaust port 75. The second casing 71 also has a top plate 711, a bottom plate 712, and four side walls 713, 714, 715, and 716. The top plate 711, the bottom plate 712, and the four side walls 713, 714, 715, and 716 are each flat.

[0117] The top plate 711 and the bottom plate 712 are parallel to the xy plane and face each other in the z-axis direction. The top plate 711 is located on the +z-axis side, and the bottom plate 712 is located on the -z-axis side. The side walls 713 and 714 are parallel to the yz plane and face each other in the x-axis direction. The side walls 713 are second walls and are located on the +x-axis side, and the side walls 714 are located on the -x-axis side. The side walls 715 and 716 are parallel to the xz plane and face each other in the y-axis direction. The side walls 715 are located on the +y-axis side, and the side walls 716 are located on the -y-axis side.

[0118] The second casing 71 can be made of various metal materials such as aluminum, stainless steel, copper alloys, etc., or various plastic materials. When the second casing 71 is made of a metal material, there is an advantage that sufficient strength is ensured and heat dissipation is excellent. The materials of the first casing 61 and the second casing 71 may be the same or different.

[0119] The second storage section 73 is an internal space that stores the first storage tool 6, other parts, devices, wiring, piping, etc. In other words, the space surrounded by the top plate 711, the bottom plate 712, and four side walls 713, 714, 715, and 716 is the second storage section 73. Examples of other devices that can be stored in the second storage section 73 include the powder collector 3, ? ?, etc.

[0120] Although not shown, the second casing 71 may have insertion holes corresponding to the first and second insertion holes described above, and insertion holes for inserting wiring, piping, etc. for devices to be stored in other than the first storage device 6. These insertion holes may be formed in any of the walls of the top plate 711, the bottom plate 712, and the four side walls 713, 714, 715, and 716.

[0121] The second intake port 74 is a circular opening provided in the side wall 713. It is provided in the center of the side wall 713 in the y-axis direction and in a position offset toward the -z-axis side from the center in the z-axis direction. The second intake port 74 communicates with the first intake port 64 and takes in the first air A1. The first air A1 taken in from the second intake port 74 is supplied to the inside of the first casing 61 via the first intake port 64.

[0122] The second intake port 74 is disposed in a position and shape such that it encompasses the first intake port 64 in a plan view of the side wall 713 (when viewed from the x-axis direction) or overlaps with most of the first intake port 64. However, this configuration is not limited, and the second intake port 74 may be disposed offset from the first intake port 64 in a plan view of the side wall 713. In this case, although not shown, it is preferable to have a connection member that connects the first intake port 64 and the second intake port 74.

[0123] The second exhaust port 75 is provided in the side wall 713. The second exhaust port 75 is provided in the side wall 713 on the +z-axis side of the second air intake port 74 and on the +y-axis side of the second air intake port 74. The second exhaust port 75 communicates with the opening 622 of the first air guide member 62. The second air A2 exhausted from the first exhaust port 65 passes through the opening 621 of the first air guide member 62, the flow path 620, the opening 622, and the second exhaust port 75 in this order, and is discharged to the outside.

[0124] 2, the second air guide member 72 is connected to the second exhaust port 75 and is installed on the +x-axis side surface of the side wall 713 so as to cover the second exhaust port 75. The second air guide member 72 guides the second air A2 discharged from the second exhaust port 75 away from the second intake port 74 and discharges it.

[0125] The opening shapes and installation positions of second intake port 74 and second exhaust port 75 are not limited to the configuration shown in the figure, and may be of any shape and in any position.

[0126] As shown in FIG. 4, the second air guide member 72 is made of a plate-shaped member and has a plurality of (ten in this embodiment) air vents 721 made of through holes, and a plurality of (ten in this embodiment) air guide plates 722.

[0127] The ventilation holes 721 extend in the z-axis direction and are arranged side by side in the y-axis direction and spaced apart from each other.

[0128] One air guide plate 722 is provided for each ventilation opening 721. The air guide plate 722 is curved or bent so as to cover the +z-axis side, the -z-axis side, and the -y-axis side of the ventilation opening 721. That is, the air guide plate 722 forms an opening that opens to the +y-axis side.

[0129] Each ventilation opening 721 communicates with the second exhaust port 75, and can change the exhaust direction (wind direction) of the second air A2 exhausted from the second exhaust port 75 to the +y-axis side. This makes it possible to prevent the second air A2 exhausted from the second exhaust port 75 from being directly sucked in from the second intake port 74. As a result, the compressor 4 can be well cooled, and compressed air can be stably generated by the compressor 4.

[0130] The second storage device 7 is not limited to the above configuration, and for example, the second casing 71 may not have a top plate 711. The second casing 71 may be missing all or part of any of the side walls 713, 714, 715, and 716. Furthermore, the second casing 71 may be made entirely or partly of a breathable material such as a frame-like material or a mesh-like material.

[0131] Thus, the storage device 5 includes the second storage 7 having the second casing 71 including the second storage section 73 for storing the first storage 6, the second intake port 74 communicating with the first intake port 64, and the second exhaust port 75 communicating with the first exhaust port 65 via the first air guide member 62. This provides a synergistic effect with the first storage 6, for example providing better soundproofing.

[0132] Further, the second casing 71 has a side wall 713 as a flat plate-shaped second wall portion, and the second intake port 74 and the second exhaust port 75 are provided in the side wall 713. This allows other structures to be placed close to or on the outer surfaces of the walls other than the side wall 713, for example, the top plate 711, the bottom plate 712, and the side walls 714, 715, and 716. This increases the degree of freedom in the layout of the device components, and also allows the device as a whole to be made more compact.

[0133] The second storage device 7 may be omitted. Even in this case, since the first air guide member 62 is provided, the second air A2 discharged from the first exhaust port 65 can be guided away from the first intake port 64 and discharged.

[0134] The second storage device 7 also includes a second air guide member 72 that is connected to the second exhaust port 75 and guides the second air A2 discharged from the second exhaust port 75 away from the second intake port 74. This makes it possible to prevent the second air A2 discharged from the second exhaust port 75 from being directly drawn in through the second intake port 74. This makes it possible to effectively cool the compressor 4 and stably generate and supply compressed air by the compressor 4. As a result, the sheet S can be manufactured more stably and satisfactorily.

[0135] Furthermore, the configuration is not limited to the above, and the direction in which the second air guide member 72 guides the second air A2 away from the second intake port 74 may be any direction. For example, any of the following may be used: a configuration in which the second air A2 is guided away from the second intake port 74 toward the -y axis side and discharged; a configuration in which the second air A2 is guided away from the second intake port 74 toward the +z axis side and discharged; a configuration in which the second air A2 is guided away from the second intake port 74 toward the -z axis side and discharged; a configuration in which the second air A2 is guided away from the second intake port 74 toward the +x axis side and discharged; and a configuration in which the second air A2 is guided away from the second intake port 74 toward the -x axis side and discharged. Any combination of these configurations may also be used.

[0136] The second air guide member 72 may be capable of adjusting the direction in which the second air A2 is discharged. For example, the installation angle of the air guide plate 722 may be changeable, or the second air guide member 72 itself may be installed to be rotatable about an axis of rotation parallel to the x-axis passing through the center of the opening 622. Moreover, the second air guide member 72 itself may be omitted.
