  However, in each of Patent Document 1, Patent Document 2, and Patent Document 3, when changing the color of a sheet in the apparatus, for example, the color change may cause a color mixture that is not desired by the user. There is no disclosure about reducing undesired color mixing. Further, when a mixed color sheet that is not desired by the user is generated, there is a problem that the sheet manufactured by the sheet manufacturing apparatus is wasted.

  An object of the present invention is to provide a fiber raw material recycling apparatus that can reduce color mixing that is not desired by the user when changing the selection of color materials when changing the color of a sheet, and waste caused by this color mixing. .

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as follows.

And in this mixing part, the defibrated material containing material and each color material can be mixed uniformly.

  In the fiber raw material recycling apparatus of the present invention, the mixing unit is disposed between the color material supply unit and the drum, and the colors of the different colors are arranged before the color material is supplied to the drum. It is preferable that the materials are mixed.

  Accordingly, when a plurality of color materials are selected by the color material selection unit, the defibrated material-containing material and each color material are supplied to the mixing unit. And the defibrated material containing material and each color material can be uniformly mixed in the mixing part at the earliest possible stage.

  In the fiber raw material recycling apparatus of the present invention, it is preferable that the drum also serves as the mixing unit.

  Thereby, when a plurality of color materials are selected by the color material selection unit, the defibrated material-containing material and each color material are supplied to the drum, that is, the mixing unit. When the drum is operated, the defibrated material-containing material and each color material can be uniformly mixed in the drum while being loosened.

Preferably, the mixing unit houses the plurality of drums, the color material is discharged from the plurality of drums together with the material, and the color materials of different colors are mixed with each other.

  Thereby, when a plurality of color materials are selected by the color material selection unit, the defibrated material-containing material and the selected color material are supplied to each drum. The defibrated material-containing material and the color material in each drum are sufficiently loosened and discharged by the operation of the drum, and can be uniformly mixed with other color materials in the mixing section.

In the fiber raw material reproduction apparatus of the present invention, the color material supply unit has a flow path through which the color materials of different colors pass independently,
Preferably, the color material selection unit includes a switching unit that is provided in each of the flow paths and switches between passing of the color material and stopping of the color material.

  Thereby, the sheet manufacturing apparatus can take the color material supply state in which the color material is supplied and the supply stop state in which the supply of the color material is stopped. As a result, a sheet having the selected color material is obtained in the color material supply state, and a sheet in which the color material is omitted is obtained in the supply stop state.

  In the fiber raw material reproduction | regeneration apparatus of this invention, it is preferable to provide the removal part which removes the residue in the said drum.

  As a result, even if the selected color material is changed, the color material before the change can be removed from the drum, so that the color material before the change and the color material after the change are changed by the user in the drum. Undesired color mixing can be prevented. Further, it is possible to prevent the waste of the sheet due to the color mixture.

<First Embodiment>
FIG. 1 is a schematic side view showing a first embodiment when the fiber raw material recycling apparatus of the present invention is applied to a sheet manufacturing apparatus. FIG. 2 is a vertical cross-sectional view showing a dispersion section and its surroundings included in the sheet manufacturing apparatus shown in FIG. FIG. 3 is a vertical cross-sectional view of a region [A] surrounded by a one-dot chain line in FIG. FIG. 4 is a vertical cross-sectional view showing a dispersion section provided in the sheet manufacturing apparatus shown in FIG. FIG. 5 is a block diagram of a main part of the sheet manufacturing apparatus shown in FIG. In the following, for convenience of explanation, the upper side in FIGS. 1 to 4 (the same applies to FIGS. 6 to 11) is referred to as “upper” or “upper”, and the lower side is referred to as “lower” or “lower”. In the following, for convenience of explanation, as shown in FIG. 1, the three axes orthogonal to each other are referred to as an x axis, a y axis, and a z axis. Further, the xy plane including the x axis and the y axis is horizontal, and the z axis is vertical. The direction in which the arrow in each direction is directed is called “positive”, and the opposite direction is called “negative”.

  As shown in FIG. 1, a sheet manufacturing apparatus (fiber material recycling apparatus) 100 is an apparatus that manufactures a sheet S. This sheet manufacturing apparatus 100 introduces at least one defibrated material-containing material (mixture M7) including defibrated material M3 obtained by defibrating paper as raw material M1, and disperses it in the air to loosen it ( In the present embodiment, the dispersion unit 18 having one cylindrical drum unit (drum) 181, the color material supply unit 3 capable of supplying a plurality of different color materials CM into the drum unit (drum) 181, A color material selection unit 4 that can select supply of each color material CM from the color material supply unit 3 to the inside of the drum unit (drum) 181.

  According to the present invention, as described later, in the sheet manufacturing apparatus 100, a desired color material CM (for example, “color material CM (C)”) can be selected by the color material selection unit 4. . The selected color material CM (C) is independent, that is, a state in which mixing with the color material CM of another color (color material CM (Y) or color material CM (M)) is reduced. Thus, it can be supplied up to the target portion (for example, the drum portion 181).

  In addition, after the color material CM (C), instead of the color material CM (C), for example, when the selection is changed to the color material CM (Y), the color material CM (Y) is changed to the color material CM. The drum portion 181 can be supplied in a state where mixing with (C) and the color material CM (M) is prevented.

  As described above, in the sheet manufacturing apparatus 100, the color mixture that is not desired by the user when the selection of the color material CM is changed (in the above case, the color material CM (Y) after selection, the color material CM (C), or the color material) is selected. Color mixing with CM (M)) can be reduced.

  In addition, when color mixing that is not desired by the user occurs, the sheet S may generally be wasted, but the sheet manufacturing apparatus 100 prevents color mixing that is not desired by the user as described above. By being configured in this way, it is possible to prevent the sheet S from being wasted.

  As shown in FIG. 1, the sheet manufacturing apparatus 100 includes a raw material supply unit 11, a crushing unit 12, a defibrating unit 13, a sorting unit 14, a first web forming unit 15, and a subdividing unit 16.

In addition, the sheet manufacturing apparatus 100 includes a blower 261, a blower 262, and a blower 263.

  Further, as shown in FIG. 5, the units included in the sheet manufacturing apparatus 100 (for example, the driving unit 187 of the dispersing unit 18, the driving unit 194 of the second web forming unit 19, the driving unit 412 of the color material selecting unit 4) are provided. The control unit 28 is electrically connected. The operations of these units are controlled by the control unit 28. The control unit 28 includes a CPU (Central Processing Unit) 281 and a storage unit 282. For example, the CPU 281 can make various determinations and various commands.

Further, the control unit 28 may be built in the sheet manufacturing apparatus 100 or may be provided in an external device such as an external computer. The external device may be connected to the sheet manufacturing apparatus 100 via a cable or the like, wirelessly connected, or connected to the sheet manufacturing apparatus 100 via a network (for example, the Internet), for example. . Further, the CPU 281 and the storage unit 282 may be integrated as a single unit, for example, or the CPU 281 is built in the sheet manufacturing apparatus 100, and the storage unit 282 is an external device such as an external computer. The storage unit 282 may be built in the sheet manufacturing apparatus 100, and the CPU 281 may be provided in an external device such as an external computer.

  Moreover, in the sheet manufacturing apparatus 100, a raw material supply process, a crushing process, a defibrating process, a sorting process, a first web forming process, a dividing process, a mixing process, a loosening process, and a second web forming process. The process, the sheet forming process, and the cutting process are executed in this order. In the sheet manufacturing apparatus 100, a color material supply process can also be executed.

Hereinafter, the configuration of each unit will be described.
The raw material supply part 11 is a part which performs the raw material supply process which supplies the raw material M1 to the crushing part 12. FIG. As this raw material M1, it is a sheet-like material containing a fiber (cellulose fiber). The cellulose fiber is not particularly limited as long as it is mainly composed of cellulose as a compound (cellulose in a narrow sense) and has a fibrous form, and may contain hemicellulose and lignin in addition to cellulose (cellulose in a narrow sense). Good. Moreover, the raw material M1 does not ask | require a form, such as a woven fabric and a nonwoven fabric. The raw material M1 may be, for example, recycled paper manufactured (regenerated) by defibrating paper or waste paper, or synthetic paper YUPO paper (registered trademark).

  The crushing unit 12 is a part that performs a crushing step of crushing the raw material M1 supplied from the raw material supply unit 11 in the air (in the air) or the like. The crushing unit 12 has a pair of crushing blades 121 and a chute (hopper) 122.

  The pair of crushing blades 121 rotate in directions opposite to each other, so that the raw material M1 can be roughly crushed between them, that is, can be cut into a roughly crushed piece M2. The shape and size of the coarsely crushed pieces M2 are preferably suitable for the defibrating process in the defibrating unit 13, and are preferably small pieces having a side length of 100 mm or less, for example, 10 mm or more and 70 mm or less. It is more preferable that

  The chute 122 is disposed below the pair of crushing blades 121 and has, for example, a funnel shape. Thereby, the chute | shoot 122 can receive the crushing piece M2 which was crushed by the crushing blade 121 and fell.

  In addition, a humidifying unit 231 is disposed adjacent to the pair of crushing blades 121 above the chute 122. The humidifying unit 231 humidifies the coarse fragments M2 in the chute 122. This humidifying unit 231 has a filter (not shown) containing moisture, and a vaporization type (or a warm air vaporization type) that supplies humidified air with increased humidity to the coarse fragments M2 by allowing air to pass through the filter. It consists of a humidifier. By supplying the humidified air to the roughly crushed pieces M2, it is possible to suppress the roughly crushed pieces M2 from adhering to the chute 122 and the like due to static electricity.

  The chute 122 is connected to the defibrating unit 13 via a tube (flow path) 241. The coarsely crushed pieces M2 collected on the chute 122 pass through the pipe 241 and are conveyed to the defibrating unit 13.

  The defibrating unit 13 is a part that performs a defibrating step of defibrating the coarsely crushed pieces M2 in the air, that is, dry. By the defibrating process in the defibrating unit 13, the defibrated material M3 can be generated from the coarsely crushed pieces M2. Here, “defibration” means to loosen the coarsely crushed piece M2 formed by binding a plurality of fibers into one fiber. Then, the unraveled material becomes the defibrated material M3. The shape of the defibrated material M3 is linear or strip-shaped. Further, the defibrated material M3 may exist in a state where they are entangled and formed into a lump, that is, in a state of forming a so-called “dama”.

  In the present embodiment, for example, the defibrating unit 13 is configured by an impeller mill having a rotor that rotates at a high speed and a liner that is positioned on the outer periphery of the rotor. The coarsely crushed pieces M2 flowing into the defibrating unit 13 are defibrated by being sandwiched between the rotor and the liner.

  Further, the defibrating unit 13 can generate a flow of air (airflow) from the crushing unit 12 toward the sorting unit 14 by rotation of the rotor. Thereby, the coarsely crushed pieces M2 can be sucked into the defibrating unit 13 from the pipe 241. In addition, after the defibrating process, the defibrated material M3 can be sent out to the sorting unit 14 via the pipe (flow path) 242.

  A blower 261 is installed in the middle of the pipe 242. The blower 261 is an airflow generation device that generates an airflow toward the sorting unit 14. Thereby, sending out of the defibrated material M3 to the sorting unit 14 is promoted.

  The sorting unit 14 is a part that performs a sorting step of sorting the defibrated material M3 according to the length of the fiber. In the sorting unit 14, the defibrated material M3 is sorted into a first sorted product M4-1 and a second sorted product M4-2 that is larger than the first sorted product M4-1. The first selected item M4-1 has a size suitable for the subsequent manufacture of the sheet S. The average length is preferably 100 μm or more and 10 mm or less. On the other hand, the second selected product M4-2 includes, for example, those in which defibration is insufficient or those in which defibrated fibers are excessively aggregated.

  The sorting unit 14 includes a drum unit 141 and a housing unit 142 that houses the drum unit 141.

The drum portion 141 is a sieve that is formed of a cylindrical mesh body and rotates around its central axis. The defibrated material M3 flows into the drum portion 141. And, by rotating the drum part 141, the defibrated material M3 smaller than the mesh opening is selected as the first selected material M4-1, and the defibrated material M3 having a size larger than the mesh opening is Sorted as second sort M4-2. In addition, the shape of the drum part 141 is not limited to a cylindrical thing, For example, polygonal cylinder shapes, such as a triangle, a quadrangle | tetragon, a hexagon, and an octagon, may be sufficient.
The first selected item M4-1 falls from the drum unit 141.

  On the other hand, the second selected item M4-2 is sent out to a pipe (flow path) 243 connected to the drum unit 141. The pipe 243 is connected to the pipe 241 on the opposite side (downstream side) from the drum portion 141. The second selection M4-2 that has passed through the pipe 243 merges with the coarsely crushed pieces M2 in the pipe 241 and flows into the defibrating unit 13 together with the coarsely crushed pieces M2. Thereby, the 2nd selection thing M4-2 is returned to the defibrating part 13, and is defibrated with the coarsely crushed piece M2.

  Moreover, the 1st selection thing M4-1 from the drum part 141 falls, disperse | distributing in air | atmosphere, and goes to the 1st web formation part (separation part) 15 located under the drum part 141. FIG. The 1st web formation part 15 is a part which performs the 1st web formation process which forms the 1st web M5 from the 1st selection thing M4-1. The first web forming unit 15 includes a mesh belt (separation belt) 151, three stretching rollers 152, and a suction unit (suction mechanism) 153.

  The mesh belt 151 is an endless belt, and the first sorted matter M4-1 is deposited thereon. The mesh belt 151 is wound around three tension rollers 152. And the 1st selection thing M4-1 on the mesh belt 151 is conveyed downstream by the rotational drive of the tension roller 152. FIG.

  The 1st selection thing M4-1 is the magnitude | size beyond the opening of the mesh belt 151. FIG. As a result, the first selected item M4-1 is restricted from passing through the mesh belt 151, and thus can be deposited on the mesh belt 151. Moreover, since the 1st selected material M4-1 is conveyed on the downstream side with the mesh belt 151, depositing on the mesh belt 151, it forms as the layered 1st web M5.

  Moreover, there exists a possibility that dust, dust, etc. may be mixed in the 1st selection thing M4-1. Dust and dust may be generated by crushing or defibration, for example. And such dust and dust will be collect | recovered by the collection | recovery parts 27 mentioned later.

  The suction unit 153 can suck air from below the mesh belt 151. Thereby, the dust and dust which passed the mesh belt 151 can be attracted | sucked with air.

  The suction unit 153 is connected to the collection unit 27 via a tube (flow path) 244. The dust sucked by the suction unit 153 is collected by the collection unit 27.

  A tube (flow path) 245 is further connected to the collection unit 27. A blower 262 is installed in the middle of the pipe 245. By the operation of the blower 262, a suction force can be generated in the suction portion 153. Thereby, formation of the 1st web M5 on the mesh belt 151 is accelerated | stimulated. The first web M5 is one from which dust, dust, etc. have been removed. In addition, dust and dirt pass through the tube 244 and reach the collection unit 27 by the operation of the blower 262.

  The housing part 142 is connected to the humidifying part 232. The humidifying unit 232 includes a vaporizing humidifier similar to the humidifying unit 231. Thereby, humidified air is supplied into the housing part 142. The humidified air can humidify the first selected item M4-1, and thus it is possible to suppress the first selected item M4-1 from adhering to the inner wall of the housing part 142 by electrostatic force.

  A humidifying unit 235 is disposed on the downstream side of the sorting unit 14. The humidifying unit 235 is composed of an ultrasonic humidifier that sprays water. Thereby, moisture can be supplied to the first web M5, and thus the moisture content of the first web M5 is adjusted. By this adjustment, adsorption of the first web M5 to the mesh belt 151 due to electrostatic force can be suppressed. Accordingly, the first web M5 is easily peeled from the mesh belt 151 at a position where the mesh belt 151 is folded back by the stretching roller 152.

  On the downstream side of the humidifying part 235, the subdividing part 16 is arranged. The subdividing portion 16 is a portion that performs a cutting step of dividing the first web M5 peeled from the mesh belt 151. The subdivision portion 16 includes a propeller 161 that is rotatably supported and a housing portion 162 that houses the propeller 161. Then, the first web M5 can be divided by the rotating propeller 161. The divided first web M5 becomes a subdivided body M6. Further, the subdivided body M6 descends in the housing portion 162.

  The housing part 162 is connected to the humidifying part 233. The humidifying unit 233 is configured by a vaporizing humidifier similar to the humidifying unit 231. Thereby, humidified air is supplied into the housing portion 162. The humidified air can also prevent the subdivided body M6 from adhering to the inner walls of the propeller 161 and the housing portion 162 due to electrostatic force.

  A mixing unit 17 is disposed on the downstream side of the subdivision unit 16. The mixing part 17 is a part which performs the mixing process which mixes the subdivided body M6 and resin P1. The mixing unit 17 includes a resin supply unit 171, a pipe (first flow path) 172, and a blower 173.

  The pipe 172 connects the subdivided portion 16 and the dispersing portion 18 and is a flow path through which the mixture M7 of the subdivided body M6 and the resin P1 passes.

  In the middle of the pipe 172, a resin supply unit 171 is connected. The resin supply unit 171 has a screw feeder 174. By rotating the screw feeder 174, the resin P1 can be supplied to the pipe 172 as powder or particles. The resin P1 supplied to the pipe 172 is mixed with the subdivided body M6 to become a mixture M7.

  The resin P1 binds the fibers in a later step. For example, a thermoplastic resin, a curable resin, or the like can be used, but a thermoplastic resin is preferably used. Examples of the thermoplastic resin include AS resin, ABS resin, polyethylene, polypropylene, polyolefin such as ethylene-vinyl acetate copolymer (EVA), modified polyolefin, acrylic resin such as polymethyl methacrylate, polyvinyl chloride, polystyrene, and polyethylene. Polyesters such as terephthalate and polybutylene terephthalate, nylon 6, nylon 46, nylon 66, nylon 610, nylon 612, nylon 11, nylon 12, nylon 6-12, nylon 6-66 and other polyamides (nylon), polyphenylene ether, polyacetal , Polyether, polyphenylene oxide, polyether ether ketone, polycarbonate, polyphenylene sulfide, thermoplastic polyimide, polyether imide, aromatic polymer Liquid crystalline polymers such as esters, various thermoplastic elastomers such as styrene, polyolefin, polyvinyl chloride, polyurethane, polyester, polyamide, polybutadiene, trans polyisoprene, fluororubber, chlorinated polyethylene, etc. 1 type selected from these, or 2 or more types can be used in combination. Preferably, as the thermoplastic resin, polyester or one containing the same is used.

  In addition to the resin P1, what is supplied from the resin supply unit 171 is, for example, an aggregation inhibitor for suppressing aggregation of fibers and aggregation of the resin P1, a flame retardant for making fibers difficult to burn, A paper strength enhancing agent for enhancing the paper strength of the sheet S may be included. Or you may supply from the resin supply part 171 what was previously included in the resin P1 (composite).

  A blower 173 is installed in the middle of the pipe 172 on the downstream side of the resin supply unit 171. The subdivided body M6 and the resin P1 are mixed by the action of a rotating part such as a blade of the blower 173. Further, the blower 173 can generate an air flow toward the dispersion unit 18. With this air flow, the sub-divided body M6 and the resin P1 can be stirred in the pipe 172. Thereby, the mixture M7 can flow into the dispersion | distribution part 18 in the state to which the subdivision M6 and resin P1 were disperse | distributed uniformly. Further, the subdivided body M6 in the mixture M7 is loosened in the process of passing through the tube 172, and becomes finer fibrous.

  In the sheet manufacturing apparatus 100, the resin P is configured to be supplied from the resin supply unit 171, but is not limited thereto. For example, the resin P may be stored in advance in a storage unit 31 described later, and may be supplied to the drum unit 181 through the channel (second channel) 32 together with the color material CM. When the supply from the resin supply unit 171 is stopped, the resin contained in the color material CM may be used as the resin P instead.

  The dispersion unit 18 is a part that performs a step of depositing the mixture M7 on the mesh belt 191 (separation belt). The dispersion unit 18 includes a drum unit 181 and a housing unit 182 that houses the drum unit 181.

The drum portion 181 is a sieve that is formed of a cylindrical mesh body and rotates about its central axis O ₁₈₁ . The mixture M7 flows into the drum portion 181. As the drum portion 181 rotates, fibers or the like smaller than the mesh openings in the mixture M7 can pass through the drum portion 181. At that time, the mixture M7 is loosened.

Note that the drum unit 181 may rotate in one direction around the central axis O ₁₈₁ , or may alternately rotate (swing) in the opposite direction around the central axis O ₁₈₁ , or a combination of these rotations. It may be one that performs. In addition, the drum unit 181 is not limited to a rotating, for example, may be one that reciprocates along a direction intersecting the central axis O ₁₈₁ direction or central axis O _181, from the central axis O ₁₈₁ You may rock | fluctuate centering on the separated position.

  Then, the mixture M7 loosened by the drum unit 181 falls while being dispersed in the air, and travels toward the second web forming unit 19 located below the drum unit 181. The 2nd web formation part 19 is a part which performs the 2nd web formation process which forms the 2nd web M8 from the mixture M7. The second web forming unit 19 includes a mesh belt (separation belt) 191, a tension roller 192, and a suction unit (suction mechanism) 193.

  The mesh belt 191 is an endless belt, and the mixture M7 is deposited thereon. The mesh belt 191 is wound around four stretching rollers 192. And the mixture M7 on the mesh belt 191 is conveyed downstream by the rotational drive of the tension roller 192.

  Further, most of the mixture M7 on the mesh belt 191 has a size larger than the mesh opening of the mesh belt 191. As a result, the mixture M7 is restricted from passing through the mesh belt 191, and can therefore be deposited on the mesh belt 191. Moreover, since the mixture M7 is conveyed on the downstream side with the mesh belt 191 while being deposited on the mesh belt 191, it is formed as a layered second web M8.

  The tension roller 192 is connected to a drive unit 194 having a drive source such as a motor, a transmission, and the like, and can be rotated at a predetermined rotation speed by the operation of the drive unit 194. The operation of the drive unit 194 is controlled by the control unit 28 (see FIG. 5). For example, the rotation speed of the stretching roller 192 can be made variable (set in multiple stages).

  The suction unit 193 can suck air from below the mesh belt 191. As a result, the mixture M7 can be sucked onto the mesh belt 191. Therefore, the deposition of the mixture M7 on the mesh belt 191 is promoted.

  A tube (flow path) 246 is connected to the suction unit 193. A blower 263 is installed in the middle of the pipe 246. By the operation of the blower 263, a suction force can be generated at the suction portion 193.

  The housing part 182 is connected to the humidifying part 234. The humidifying unit 234 includes a vaporizing humidifier similar to the humidifying unit 231. Thereby, humidified air is supplied into the housing portion 182. The inside of the housing part 182 can be humidified by the humidified air, so that the mixture M7 can be prevented from adhering to the inner wall of the housing part 182 by electrostatic force.

  A humidification unit 236 is disposed on the downstream side of the dispersion unit 18. The humidifying unit 236 is configured by an ultrasonic humidifier similar to the humidifying unit 235. Thereby, moisture can be supplied to the second web M8, and thus the moisture content of the second web M8 is adjusted. By this adjustment, adsorption of the second web M8 to the mesh belt 191 due to the electrostatic force can be suppressed. Thereby, the second web M8 is easily peeled from the mesh belt 191 at a position where the mesh belt 191 is folded back by the stretching roller 192.

  In addition, it is preferable that the moisture amount (total moisture amount) added to the humidification part 231-the humidification part 236 is 0.5 mass part or more and 20 mass parts or less with respect to 100 mass parts of materials before humidification, for example.

  The pressurizing unit 201 includes a pair of calendar rollers 203, and can pressurize the second web M8 between the calendar rollers 203 without heating (without melting the resin P1). Thereby, the density of the 2nd web M8 is raised. Then, the second web M8 is conveyed toward the heating unit 202. One of the pair of calendar rollers 203 is a main driving roller driven by the operation of a motor (not shown), and the other is a driven roller.

  The heating unit 202 includes a pair of heating rollers 204, and can apply pressure while heating the second web M8 between the heating rollers 204. By this heating and pressing, the resin P1 is melted in the second web M8, and the fibers are bound to each other through the melted resin P1. Thereby, the sheet S is formed. The sheet S is conveyed toward the cutting unit 21. One of the pair of heating rollers 204 is a main driving roller driven by the operation of a motor (not shown), and the other is a driven roller.

  A cutting unit 21 is disposed on the downstream side of the sheet forming unit 20. The cutting unit 21 is a part that performs a cutting process of cutting the sheet S. The cutting unit 21 includes a first cutter 211 and a second cutter 212.

  The second cutter 212 cuts the sheet S in a direction parallel to the conveying direction of the sheet S on the downstream side of the first cutter 211.

  By cutting the first cutter 211 and the second cutter 212 in this manner, a sheet S having a desired size can be obtained. The sheet S is further conveyed downstream and accumulated in the stock unit 22.

  Now, the sheet manufacturing apparatus 100 is configured to be able to manufacture a colored sheet S. Hereinafter, this configuration and operation will be described.

  As described above, the dispersion unit 18 performs a process of loosening the mixture M7 which is a mixture of the subdivided body M6 (defibrated material M3) and the resin P1. As a result, the mixture M7 is uniformly removed in the air, that is, the state of being intertwined into a lump is eliminated, falls while being dispersed, and accumulates on the mesh belt 191 of the second web forming unit 19. .

  Moreover, the inflow port 183 into which the mixture M7 flows in is connected to the both ends of the drum part 181 respectively. Each inflow port 183 has, for example, an annular shape, a cylindrical shape, or a circular tube shape, and is inserted inside each end portion of the drum portion 181. Each inflow port 183 communicates with the pipe 172 on the downstream side. Accordingly, the mixture M7 that has passed through the pipe 172 can flow into the drum portion 181 through each inflow port 183.

  Further, the lower side of the housing portion 182 that houses the drum portion 181 is open toward the mesh belt 191. Accordingly, the mixture M7 that has passed through the opening 181a of the drum unit 181 can fall on the mesh belt 191 and be accumulated.

  As shown in FIG. 2, a second web forming unit 19 (deposition unit) is provided on the lower side (outer peripheral side) of the drum unit 181. The second web forming portion 19 is a portion where the mixture M7 that has passed through the opening 181a of the drum portion 181 is deposited. Then, the mixture M7 as a deposit deposited on the second web forming unit 19 becomes a layered second web M8.

  As described above, the second web forming unit 19 includes the mesh belt 191 on which the second web M8 is deposited and transports the second web M8. The mesh belt 191 has a plurality of through holes 191a formed so as to penetrate in the thickness direction. Note that the shape of the through hole 191a in plan view is not particularly limited, and for example, a circular shape, an elliptical shape, an oval shape, a polygonal shape, or the like is preferable. In addition, the size of the through hole 191a in plan view is not particularly limited. For example, when the through hole 191a is circular, the diameter is preferably 0.02 mm or more and 2 mm or less, and 0.05 mm or more and 1 mm or less. It is more preferable that Moreover, when the through-hole 191a is circular, it is preferable that a diameter is 0.5 mm or more and 5 mm or less, and it is more preferable that it is 2 mm or more and 3 mm or less. Moreover, it does not specifically limit as a formation method of the through-hole 191a, For example, the method by machining, such as punching, can be used. Further, among machining, a method by laser machining or etching can also be used. Further, as the mesh belt 191, a resin net, a metal net, or an expanded metal can be used.

  As shown in FIGS. 1 and 2, the color material supply unit 3 is disposed on the upstream side of the drum unit 181 of the dispersion unit 18. The color material supply unit 3 is a part that performs a color material supply process of supplying the color material CM selected by the color material selection unit 4 to the drum unit 181 of the dispersion unit 18.

  There are a plurality of different color materials CM. In this embodiment, as an example, at least three color materials CM having different colors are listed. These three color materials CM are pigments having chromatic colors, for example, cyan (C), yellow (Y), and magenta (M). Hereinafter, the cyan color material CM is referred to as “color material CM (C)”, the yellow color material CM is referred to as “color material CM (Y)”, and the magenta color material CM is referred to as “color material CM (M)”. There is. Note that the color of each color material CM is not limited to cyan, yellow, and magenta.

  As shown in FIG. 2, the color material supply unit 3 includes a storage unit 31 that stores the color material CM (C), the color material CM (Y), and the color material CM (M) independently, and each storage unit 31. And a flow path 32 connected to the. Each storage unit 31 and each flow path 32 have the same configuration except that the color material CM supplied to the drum unit 181 is different, and hence is connected to one storage unit 31 and the storage unit 31 below. The flow path 32 will be described representatively.

  As shown in FIG. 3, the storage part 31 is comprised with the hollow body which has the storage space 311 which stores the color material CM inside. The storage unit 31 is detachably loaded into a loading unit 33 provided in the sheet manufacturing apparatus 100. In this loaded state, the storage space 311 of the storage unit 31 communicates with the flow path 32. Thereby, the color material CM can flow into the flow path 32.

  The storage unit 31 is preferably a cartridge. Thereby, when the storage unit 31 becomes empty, that is, when the color material CM is used up, it can be replaced with a new storage unit 31. In the sheet manufacturing apparatus 100, the remaining amount of the color material CM in the storage unit 31 is detected by a remaining amount detection unit (not shown).

  As shown in FIG. 2, the flow path 32 is connected to the storage part 31 on the upstream side and connected to the inflow port 183 of the dispersion part 18 on the downstream side. Accordingly, the color material CM can pass through the flow path 32 independently from the storage unit 31 to the inflow port 183, that is, in a state where mixing with the other color material CM is prevented.

  The flow path 32 is configured by, for example, a pipe 321. The pipe 321 includes a branch pipe 323 and a branch pipe 324 that are branched into two via a branch portion 322. The branch pipe 323 can be connected to one inflow port 183 of the two inflow ports 183, and the branch pipe 324 can be connected to the other inflow port 183. Thereby, the storage part 31 and each inflow port 183 are connected via the flow path 32. In the drum portion 181, the mixture M7 and the color material CM can merge, and thus a mixture M7 ′ including the mixture M7 and the color material CM is generated.

  The color material selection unit 4 selectively supplies each color material CM from the color material supply unit 3 to the drum unit 181.

  As described above, the color material supply unit 3 includes the flow paths 32 through which the color materials CM of different colors pass independently. As shown in FIG. 2, the color material selection unit 4 includes a switching unit 41 that is provided in each flow path 32 and switches between the passage of the color material CM and the stop of the passage. Thereby, the sheet manufacturing apparatus 100 can take the color material supply state in which the color material CM is supplied and the supply stop state in which the supply of the color material CM is stopped. Thereby, the sheet S having the selected color material CM is obtained in the color material supply state, and the sheet S from which the color material CM is omitted is obtained in the supply stop state.

  As shown in FIG. 3, the switching unit 41 is a screw feeder, and includes a screw 411 that is concentrically inserted into the flow path 32 (tube 321), and a drive unit 412 that rotationally drives the screw 411. Yes.

  By rotating the screw 411, the color material CM can be pulled out from the storage unit 31 and pushed out toward the downstream side as it is. Thereby, the color material CM can pass through the flow path 32 and reach the drum portion 181. Further, when the rotation of the screw 411 is stopped, the extrusion of the color material CM is also stopped.

  The drive unit 412 is configured by, for example, a motor. Further, as shown in FIG. 5, the drive unit 412 is electrically connected to the control unit 28. As a result, the operation of the drive unit 412 is controlled by the control unit 28, so that the number of rotations of the screw 411 can be made variable. The supply amount and supply speed of the color material CM can be adjusted depending on the number of rotations of the screw 411. Therefore, for example, a sheet S having a desired color shade can be obtained. Note that the operation information of the drive unit 412 is previously input and stored in the control unit 28 via an input unit such as a keyboard or a touch panel (not shown).

  The color material selection unit 4 having the above-described configuration can selectively supply the color material CM. As a result, any one of the color material CM (C), the color material CM (Y), and the color material CM (M) is supplied to the drum unit 181 alone, or the color material CM (C), the color material At least two color materials CM of the material CM (Y) and the color material CM (M) can be combined and supplied to the drum unit 181. Further, when the color materials CM are combined, the mixing ratio of the color materials CM can be adjusted by changing the rotational speed of the screw 411.

  In addition, the switching part 41 is not limited to a screw feeder, For example, you may have a belt conveyance mechanism.

  As shown in FIG. 2, the sheet manufacturing apparatus 100 includes a mixing unit 5 that mixes color materials CM selected by the color material selection unit 4 and having different colors. In the present embodiment, the drum unit (drum) 181 also serves as the mixing unit 5.

When a plurality of color materials CM are selected by the color material selection unit 4, the mixture M7 and each color material CM are supplied as a mixture M7 ′ to the drum unit 181, that is, the mixing unit 5. Then, when the drum portion 181 rotates around the central axis O ₁₈₁ , the mixture M <b> 7 and each color material CM can be uniformly mixed in the drum portion 181 while being loosened.

  As shown in FIG. 2, the drum portion (drum) 181 has a plurality of openings 181a as discharge portions for discharging the color material CM together with the mixture M7 (defibrated material-containing material).

  The sheet manufacturing apparatus 100 forms a second web M8 (web) using the mixture M7 (defibrated material-containing material) that has been unwound and processed by the dispersing unit 18 (unraveling process) (second web forming unit 19 (web)). Web forming unit). Specifically, the sheet manufacturing apparatus 100 is disposed on the downstream side of the drum unit (drum) 181, and the mixture M7 (defibrated material-containing material) discharged through the opening 181a (discharge unit) and each color material CM. That is, the second web forming unit 19 (web forming unit) is formed to form the second web M8 (web) by the mixture M7 ′. Thereby, based on the 2nd web M8, it can manufacture the color sheet | seat S which has the color which the color of each color material CM mixed. Further, by adjusting the mixing ratio of the color materials CM as described above, a sheet S rich in gradation can be manufactured even with the same color mixture. When any one of the color material CM (C), the color material CM (Y), and the color material CM (M) is supplied to the drum unit 181 alone, cyan, yellow, or magenta single color The sheet S can also be manufactured. Thus, the sheet manufacturing apparatus 100 can manufacture the sheet S having a desired color. Further, if the sheet manufacturing apparatus 100 stops the supply of the color material CM, the sheet S in which the color is omitted can be manufactured.

  In the sheet manufacturing apparatus 100 configured as described above, the color material selection unit 4 can select a desired color material CM (for example, “color material CM (C)”). Then, the selected color material CM (C) is independent, that is, in a state where mixing with the color material CM of another color (color material CM (Y) or color material CM (M)) is prevented. The drum portion 181 (inflow port 183) can be supplied.

  Further, instead of the color material CM (C), for example, when the selection is changed to the color material CM (Y), the color material CM (Y) is used as the color material CM (C) or the color material CM (M). The drum portion 181 can be supplied in a state where mixing with the drum portion is prevented.

  As described above, in the sheet manufacturing apparatus 100, the color mixture that is not desired by the user when the selection of the color material CM is changed (in the above case, the color material CM (Y) after selection, the color material CM (C), or the color material) is selected. Color mixing with CM (M) can be prevented.

  In addition, when color mixing that is not desired by the user occurs, the sheet S may generally be wasted, but the sheet manufacturing apparatus 100 prevents color mixing that is not desired by the user as described above. By being configured in this way, it is possible to prevent the sheet S from being wasted.

  As shown in FIG. 4, the sheet manufacturing apparatus 100 includes a removing unit 6 that removes residues in the drum unit (drum) 181. The removal unit 6 includes a plate-like squeegee 61 that extends along the y direction and contacts the inner peripheral portion 181b of the drum portion 181. The position and posture of the squeegee 61 are kept constant regardless of the rotation of the drum unit 181. Residue adhering to the inner peripheral portion 181b of the drum portion 181 is scraped off by the squeegee 61 when the drum portion 181 rotates. The scraped residue is discharged from, for example, a discharge port (not shown) communicating with the drum portion 181. Examples of the residue include a mixture M7 'containing a color material CM.

  Even if the selected color material CM is changed by the removing unit 6 having such a configuration, the color material CM before the change can be removed from the drum unit 181. Thereby, it is possible to prevent the color material CM before the change and the color material CM after the change from being mixed in the drum unit 181 which is not desired by the user. Further, it is possible to prevent the sheet S from being wasted due to this color mixture.
