  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The embodiments described below do not unduly limit the contents of the present invention described in the claims. In addition, not all of the configurations described below are essential constituent requirements of the present invention.

  First, the details of each processing unit in the sheet manufacturing apparatus according to the present embodiment will be described with reference to FIG. 1, and then the arrangement of each processing unit in the sheet manufacturing apparatus will be described with reference to FIGS.

1. Sheet manufacturing apparatus 1.1. Configuration First, a sheet manufacturing apparatus according to the present embodiment will be described with reference to the drawings. FIG. 1 is a diagram schematically illustrating a sheet manufacturing apparatus 100 according to the present embodiment.

  As shown in FIG. 1, the sheet manufacturing apparatus 100 includes a supply unit 10, a manufacturing unit 102, and a control unit 140. The manufacturing unit 102 manufactures a sheet. The manufacturing unit 102 includes a crushing unit 12, a defibrating unit 20, a classifying unit 30, a sorting unit 40, a mixing unit 50, a depositing unit 60, a web forming unit 70, a sheet forming unit 80, and a cutting unit. Part 90.

  The supply unit 10 supplies raw materials to the crushing unit 12. The supply unit 10 is, for example, an automatic input unit for continuously supplying raw materials to the crushing unit 12.

  The crushing unit 12 cuts the raw material supplied by the supply unit 10 into air into pieces. The shape and size of the strip is, for example, a strip of several cm square. In the illustrated example, the crushing unit 12 has a crushing blade 14, and the charged raw material can be cut by the crushing blade 14. As the crushing part 12, a shredder is used, for example. The raw material cut by the crushing unit 12 is received by the hopper 1 and then transferred (conveyed) to the defibrating unit 20 through the pipe 2.

  The defibrating unit 20 defibrates the raw material cut by the crushing unit 12. Here, “defibration” means unraveling a raw material (a material to be defibrated) formed by binding a plurality of fibers into individual fibers. The defibrating unit 20 also has a function of separating substances such as resin particles, ink, toner, and a bleeding inhibitor adhering to the raw material from the fibers.

  What has passed through the defibrating unit 20 is referred to as “defibrated material”. In addition to the defibrated fibers that have been unraveled, the “defibrated material” includes resin particles (resins that bind multiple fibers together), ink, toner, etc. In some cases, additives such as colorants, anti-bleeding materials, and paper strength enhancing agents are included. The shape of the defibrated material that has been unraveled is a string shape or a ribbon shape. The unraveled defibrated material may exist in an unentangled state (independent state) with other undisentangled fibers, or entangled with other undisentangled defibrated material to form a lump. It may exist in a state (a state forming a so-called “dama”).

  The defibrating unit 20 defibrates in a dry manner in the atmosphere (in the air). Specifically, an impeller mill is used as the defibrating unit 20. The defibrating unit 20 has a function of generating an air flow that sucks the raw material and discharges the defibrated material. Thereby, the defibrating unit 20 can suck the raw material together with the airflow from the introduction port 22 by the airflow generated by itself, defibrate it, and transport it to the discharge port 24. The defibrated material that has passed through the defibrating unit 20 is transferred to the classifying unit 30 via the tube 3.

  The classifying unit 30 classifies the defibrated material that has passed through the defibrating unit 20. Specifically, the classifying unit 30 separates and removes relatively small ones or low density ones (resin particles, colorants, additives, etc.) among the defibrated materials. Thereby, the ratio for which the fiber which is a comparatively large or high density thing among defibrated materials can be raised.

As the classification unit 30, an airflow classifier is used. The airflow classifier generates a swirling airflow and separates it according to the difference in centrifugal force depending on the size and density of what is classified, and the classification point can be adjusted by adjusting the speed and centrifugal force of the airflow. it can. Specifically, a cyclone, an elbow jet, an eddy classifier, or the like is used as the classification unit 30. In particular, a cyclone as shown in the figure can be suitably used as the classifying unit 30 because of its simple structure.

  The classification unit 30 includes, for example, an inlet 31, a cylindrical part 32 to which the inlet 31 is connected, an inverted conical part 33 that is located below the cylindrical part 32 and continues to the cylindrical part 32, and an inverted conical part 33. The lower discharge port 34 provided in the lower center of the upper portion and the upper discharge port 35 provided in the upper center of the cylindrical portion 32 are provided.

  In the classification unit 30, the airflow on which the defibrated material introduced from the introduction port 31 is changed into a circumferential motion in the cylindrical unit 32. As a result, centrifugal force is applied to the introduced defibrated material, and the classification unit 30 includes fibers (first classified material) larger than the resin particles and ink particles in the defibrated material, and the defibrated material. Among them, it can be separated into resin particles, colorants, additives, etc. (second classified product) that are smaller than the fibers and have a low density. The first classified product is discharged from the lower discharge port 34 and is introduced into the sorting unit 40 through the pipe 4. On the other hand, the second classified product is discharged from the upper discharge port 35 to the receiving portion 36 through the pipe 5.

  The sorting unit 40 introduces the first classified product that has passed through the classifying unit 30 from the introduction port 42 and sorts the first classified product according to the length of the fiber. As the selection unit 40, for example, a sieve is used. The sorting unit 40 has a net (filter, screen), and includes fibers or particles (those that pass through the net, the first sort) that are smaller than the mesh size included in the first classification, Fibers that are larger than the size of the mesh, undefibrated pieces, and lumps (those that do not pass through the net, second selection) can be separated. For example, the first selection is received by the hopper 6 and then transferred to the mixing unit 50 via the pipe 7. The second selected item is returned to the defibrating unit 20 from the discharge port 44 through the pipe 8. Specifically, the sorting unit 40 is a cylindrical sieve that can be rotated by a motor. For the net of the selection unit 40, for example, a metal net, an expanded metal obtained by extending a cut metal plate, or a punching metal in which a hole is formed in the metal plate by a press machine or the like is used.

  The mixing part 50 mixes the 1st selection thing which passed the selection part 40, and the additive containing resin. The mixing unit 50 includes an additive supply unit 52 that supplies the additive, a pipe 54 that conveys the selected product and the additive, and a blower 56. In the illustrated example, the additive is supplied from the additive supply unit 52 to the pipe 54 via the hopper 9. The tube 54 is continuous with the tube 7.

  In the mixing unit 50, an air flow is generated by the blower 56, and the first selection product and the additive can be mixed and conveyed in the pipe 54. In addition, the mechanism which mixes a 1st selection material and an additive is not specifically limited, It may stir with the blade | wing which rotates at high speed, and uses rotation of a container like a V-type mixer. There may be.

  As the additive supply unit 52, a screw feeder as shown in FIG. 1 or a disk feeder (not shown) is used. The additive supplied from the additive supply unit 52 includes a resin for binding a plurality of fibers. At the time when the resin is supplied, the plurality of fibers are not bound. The resin melts when passing through the sheet forming portion 80 and binds a plurality of fibers.

  The resin supplied from the additive supply unit 52 is a thermoplastic resin or a thermosetting resin. For example, AS resin, ABS resin, polypropylene, polyethylene, polyvinyl chloride, polystyrene, acrylic resin, polyester resin, polyethylene terephthalate, Polyphenylene ether, polybutylene terephthalate, nylon, polyamide, polycarbonate, polyacetal, polyphenylene sulfide, polyether ether ketone, and the like. These resins may be used alone or in combination. The additive supplied from the additive supply unit 52 may be fibrous or powdery.

In addition to the resin that binds the fibers, the additive supplied from the additive supply unit 52 prevents coloring of the fibers and the aggregation of the fibers depending on the type of sheet to be produced. An anti-agglomeration material, a flame retardant for making the fiber and the like difficult to burn may be included. The mixture (mixture of the first classified product and the additive) that has passed through the mixing unit 50 is transferred to the deposition unit 60 via the pipe 54.

  The depositing unit 60 introduces the mixture that has passed through the mixing unit 50 from the introduction port 62, loosens the entangled defibrated material (fibers), and lowers it while dispersing it in the air. Furthermore, when the additive resin supplied from the additive supply unit 52 is fibrous, the deposition unit 60 loosens the entangled resin. Thereby, the deposition unit 60 can deposit the mixture on the web forming unit 70 with good uniformity.

  As the deposition unit 60, a rotating cylindrical sieve is used. The deposition unit 60 has a net, and drops fibers or particles (those that pass through the net) included in the mixture that has passed through the mixing unit 50 that are smaller than the mesh opening size. The configuration of the deposition unit 60 is the same as the configuration of the sorting unit 40, for example.

  It should be noted that the “sieving” of the depositing unit 60 may not have a function of selecting a specific object. That is, the “sieving” used as the depositing unit 60 means that the net is provided, and the depositing unit 60 may drop all of the mixture introduced into the depositing unit 60.

  The web forming unit 70 deposits the passing material that has passed through the deposition unit 60 to form the web W. The web forming unit 70 includes, for example, a mesh belt 72, a tension roller 74, and a suction mechanism 76.

  While moving, the mesh belt 72 accumulates the passing material that has passed through the opening of the accumulation unit 60 (the opening of the mesh). The mesh belt 72 is stretched by a stretching roller 74, and is configured to allow air to pass therethrough. The mesh belt 72 moves as the stretching roller 74 rotates. While the mesh belt 72 continuously moves, the passing material that has passed through the accumulation portion 60 is continuously piled up, whereby the web W is formed on the mesh belt 72. The mesh belt 72 is made of, for example, metal, resin, cloth, or non-woven fabric.

  The suction mechanism 76 is provided below the mesh belt 72 (on the side opposite to the accumulation unit 60 side). The suction mechanism 76 can generate an air flow directed downward (air flow directed from the accumulation unit 60 toward the mesh belt 72). By the suction mechanism 76, the mixture dispersed in the air by the deposition unit 60 can be sucked onto the mesh belt 72. Thereby, the discharge speed from the deposition part 60 can be increased. Furthermore, the suction mechanism 76 can form a downflow in the dropping path of the mixture, and can prevent the defibrated material and additives from being entangled during the dropping.

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

  In the illustrated example, a humidity control unit 78 that adjusts the humidity of the web W is provided. The humidity control unit 78 can adjust the amount ratio of the web W and water by adding water or water vapor to the web W.

The sheet forming unit 80 forms the sheet S by pressurizing and heating the web W deposited on the mesh belt 72. In the sheet forming unit 80, by heating the mixture of the defibrated material and the additive mixed in the web W, the plurality of fibers in the mixture are bound to each other via the additive (resin). Can do.

  As the sheet forming unit 80, for example, a heating roller (heater roller), a hot press molding machine, a hot plate, a hot air blower, an infrared heater, or a flash fixing device is used. In the illustrated example, the sheet forming unit 80 includes a first binding unit 82 and a second binding unit 84, and the binding units 82 and 84 each include a pair of heating rollers 86. Since the binding portions 82 and 84 are configured as the heating roller 86, the web W is continuously conveyed as compared with the case where the binding portions 82 and 84 are configured as a plate-like press device (flat plate press device). Sheet S can be formed. The number of heating rollers 86 is not particularly limited.

  The cutting unit 90 cuts the sheet S formed by the sheet forming unit 80. In the illustrated example, the cutting unit 90 includes a first cutting unit 92 that cuts the sheet S in a direction that intersects the conveyance direction of the sheet S, and a second cutting unit 94 that cuts the sheet S in a direction parallel to the conveyance direction. ,have. The second cutting unit 94 cuts the sheet S that has passed through the first cutting unit 92, for example.

  Thus, a single-sheet sheet S having a predetermined size is formed. The cut sheet S is discharged to the discharge unit 96.

1.2. Arrangement The arrangement of the processing units in the sheet manufacturing apparatus 100 will be described with reference to FIG. FIG. 2 is a plan view of the sheet manufacturing apparatus 100 according to the present embodiment. Since each processing unit of the sheet manufacturing apparatus 100 in FIG. 2 has already been described in “1.1. Configuration”, a duplicate description is omitted.

  In FIG. 2, the side on which the operation unit 141 (control unit 140) is arranged is the front side of the sheet manufacturing apparatus 100. Here, the “front side” of the sheet manufacturing apparatus 100 means a portion in front of the sheet manufacturing apparatus 100.

  As shown in FIG. 2, the sheet manufacturing apparatus 100 has a rectangular outer shape in plan view of the apparatus main body 150 excluding the supply unit 10 and the discharge unit 96, and four first to fourth side walls 150 a to 150 d on four sides thereof. Have The front first side wall 150a is the front surface of the sheet manufacturing apparatus 100 and is disposed to face the rear second side wall 150b. The third side wall 150c and the fourth side wall 150d are arranged so as to connect both ends of the first side wall 150a and both ends of the second side wall 150b. The supply unit 10 and the discharge unit 96 are disposed outside the apparatus main body 150 and are adjacent to the third side wall 150c and the fourth side wall 150d, respectively. In the present embodiment, the first and second side walls 150a and 150b are longer than the third and fourth side walls 150c and 150d, and the apparatus main body 150 is rectangular in plan view. The first to fourth side walls 150a to 150d are substantially rectangular plate-like bodies having the same height, and therefore the apparatus main body 150 is a substantially rectangular parallelepiped.

  The sheet manufacturing apparatus 100 has two transport lines A and B for transporting raw materials or sheets S in the front and rear. The supply unit 10 is disposed adjacent to the outer surface of the third side wall 150c and closer to the second side wall 150b. The rear conveyance line A to which the supply unit 10 is connected is formed by the crushing unit 12, the sorting unit 40, the classifying unit 30, and the defibrating unit 20 on the second side wall 150b side from the third side wall 150c to the fourth side wall 150d. Arranged in order. Then, the front conveyance line B has a stacking unit 60, a mixing unit 50, a sheet forming unit 80 (a pressurizing unit 81, a heating unit 83), and a cutting on the first side wall 150a side from the third side wall 150c to the fourth side wall 150d. The parts 90 are arranged in this order. A discharge unit 96 is connected to the front conveyance line B. The discharge portion 96 is disposed adjacent to the outer surface of the fourth side wall 150d and closer to the first side wall 150a.

  The processing order of each processing unit is as described in “1.1. Configuration”. In FIG. 2, the processing order is indicated by a solid arrow connecting the processing units. Each processing unit will be described in the order of these arrows. In the rear conveyance line A of the sheet manufacturing apparatus 100, the raw material is supplied from the supply unit 10 into the apparatus main body 150, and is crushed at the crushing unit 12 on the third side wall 150c side. To the defibrating unit 20 on the side, defibrated by the defibrating unit 20 to become a defibrated material, the defibrated material is classified by the classifying unit 30 near the center of the apparatus body 150 and becomes a first classified product, The first classified product is sorted by the sorting unit 40 and is sent to the front conveyance line B as the first sorted product. In the front conveyance line B of the sheet manufacturing apparatus 100, the first selection product is mixed with the additive containing the resin in the mixing unit 50 to be a mixture, and the mixture is conveyed to the deposition unit 60 on the third side wall 150c side. It is loosened and deposited on the web forming unit 70 to form a web. The web is conveyed to the sheet forming unit 80 and formed into a continuous sheet, and the continuous sheet is conveyed to the cutting unit 90 on the fourth side wall 150d side to be a cut sheet. And is discharged to a discharge portion 96 outside the apparatus main body 150.

  In the present embodiment, an example in which two lines of conveyance lines are used has been described. However, the present invention is not limited to this, and three or more lines of conveyance lines may be used.

2. Rear Transfer Line The rear transfer line A will be described in detail with reference to FIG. FIG. 3 is a rear view of the sheet manufacturing apparatus 100 according to the present embodiment.

  As shown in FIG. 3, the rear conveyance line A of the sheet manufacturing apparatus 100 includes a supply unit 10 that supplies a raw material containing fibers, a crushing unit 12 that crushes the raw material supplied by the supply unit 10, and a coarse crushing The funnel-shaped hopper 1 which is a receiving part for receiving the coarsely crushed pieces crushed by the part 12, the defibrating part 20 for defibrating the coarsely crushed pieces into the defibrated material, and the crushed pieces from the hopper 1 to the defibrated part 20 And a pipe 2 which is a transport unit.

  The supply unit 10 is detachable from the third side wall 150c of the apparatus main body 150 and supplies the raw material into the apparatus main body 150 from a supply opening 152 that is an opening provided in the third side wall 150c. It is preferable to arrange the supply unit 10 as low as possible in the sheet manufacturing apparatus 100. This is because the sheet manufacturing apparatus 100 can be easily cleaned in this way. For example, when a paper jam occurs during paper feeding, the material with the lower position of the supply unit 10 is easily removed from the supply unit 10. Moreover, if the position of the supply unit 10 is low, for example, the supply unit 10 is slid on the installation floor surface by a caster (not shown), so that it is easy to cope with the material clogged on the apparatus main body 150 side.

  The apparatus main body 150 includes a machine base 150e disposed to face a floor surface of an office or the like in which the sheet manufacturing apparatus 100 is installed, and the first side wall 150a to the fourth side wall 150d so as to rise from both ends of the machine base 150e. (For the first and second side walls 150a and 150b, see FIG. 1) is fixed. On the machine base 150e, the hopper 1, the selection part 40, the blower 37, and the defibrating part 20 are installed in order from the 3rd side wall 150c via the some support stand which is not shown in figure.

  In the sheet manufacturing apparatus 100, the defibrating unit 20 is disposed on one end side of the sheet manufacturing apparatus 100, and the hopper 1 is disposed on the other end side of the sheet manufacturing apparatus 100. As described above, the defibrating unit 20 and the hopper 1 of the sheet manufacturing apparatus 100 are arranged by disposing the defibrating unit 20 on one end side of the sheet manufacturing apparatus 100 and disposing the hopper 1 on the other end side of the sheet manufacturing apparatus 100. Located apart in. Therefore, the noise in the defibrating unit 20 is attenuated in the pipe 2 until it comes out from the opening of the hopper 1, and the noise can be reduced.

Here, the one end side and the other end side of the sheet manufacturing apparatus 100 can be rephrased as the third side wall 150 c side and the fourth side wall 150 d side of the apparatus main body 150. Further, the sheet manufacturing apparatus 100
The one end side and the other end side mean the one end side and the other end side of the intermediate position when the sheet manufacturing apparatus 100 is divided into two equal parts.

  Since the noise can be attenuated as long as the defibrating unit 20 and the hopper 1 are separated from each other, the position where the longest distance can be taken in the sheet manufacturing apparatus 100, that is, the defibrating unit 20 is preferably adjacent to the vicinity of the fourth side wall 150d. The hopper 1 is preferably disposed adjacent to the third side wall 150c.

  The pipe 2 upstream of the defibrating unit 20 has a silencer 21 in the conveying direction of the coarsely crushed pieces. By having the silencer 21, noise generated in the defibrating unit 20 can be reduced.

  One or more silencers 21 may be provided in the middle of the tube 2. The silencer 21 is preferably disposed above the defibrating unit 20, and is preferably disposed in the middle of the pipe 2 extending upward from the defibrating unit 20. Although details of the silencer 21 will be described later, since the silencer 21 has a large number of openings, it is preferably disposed in the middle of the pipe 2 extending in the vertical direction from the defibrating unit 20. This is to prevent the coarse fragments from being caught in the opening of the muffler 21 and closing the opening. Here, the “vertical direction” includes a substantially vertical direction inclined from the vertical direction within a range in which the opening can be prevented from being clogged with coarse fragments, and may be inclined, for example, 45 degrees with respect to the vertical direction.

  The tube 2 is disposed so as to be inclined from below the hopper 1 toward above the defibrating unit 20. By arranging the pipe 2 at an inclination, the length of the pipe 2 can be increased in the apparatus main body 150, and noise can be further attenuated. Moreover, since the pipe 2 can be arranged at an inclination, a part extending upward from the defibrating unit 20 can be provided in a part of the pipe 2, so that the muffling part 21 can be arranged in a part extending upward. .

  It is preferable to make the inclination of the tube 2 as gentle as possible (decrease the gradient). Since the conveyance of the raw material in the pipe 2 is performed by the wind force generated in the defibrating unit 20, the raw material can be easily conveyed by reducing the gradient of the pipe 2. In order to reduce the gradient of the tube 2, the defibrating unit 20 is preferably arranged on the lower side of the sheet manufacturing apparatus 100 as possible, for example, on the machine base 150e. The defibrating unit 20 is installed on the machine base 150e via rubber for vibration isolation. By using the rubber for vibration isolation, the vibration of the defibrating unit 20 can be attenuated, and the noise caused by the vibration transmitted to the machine base 150e can also be reduced. Further, in order to reduce the gradient of the pipe 2, it is preferable to dispose the hopper 1 on the upper side of the sheet manufacturing apparatus 100. However, the height of the hopper 1 is inevitably due to the arrangement of the supply unit 10 described above. Lower position.

  The blower 37 sucks in the defibrated material from the defibrating unit 20 by the air generated in the pipe 3 and conveys the defibrated material to the classifying unit 30.

  The classification unit 30 is, for example, a cyclone, and is obliquely connected via the pipe 4 above the sorting unit 40.

  The selection unit 40 has a sieve 45. The sorting unit 40 sorts the defibrated material that has been defibrated by the defibrating unit 20 into a passing material that passes through the sieve 45 and a non-passing material that does not pass through the sieve 45. In the conveying direction of the coarsely crushed pieces from the hopper 1 to the defibrating unit 20, the sorting unit 40 is disposed between the hopper 1 and the defibrating unit 20. Therefore, by arranging the selection unit 40 in a space formed by arranging the hopper 1 and the defibrating unit 20 apart, it is possible to achieve a highly space-efficient arrangement and reduce noise.

  The sorting unit 40 has a hopper 6 below, and the sorted first sorted product is conveyed to the mixing unit 50 on the front side via the pipe 54.

  Further, the sorting unit 40 includes a discharge port 44 and a pipe 8 that are discharge units that discharge non-passing materials that do not pass through. The discharge port 44 opens to the third side wall 150 c side of the sorting unit 40, and the tube 8 has one end connected to the discharge port 44 and the other end opened onto the hopper 1. The hopper 1 is located at a position where a non-passing object falls by its own weight from the discharge port 44. Therefore, the non-passing matter that has not passed through the sorting unit 40 can be discharged to the hopper 1 by its own weight along the pipe 8 regardless of the conveying force such as the blower.

3. Front Transport Line The front transport line B will be described in detail with reference to FIG. FIG. 4 is a front view of the sheet manufacturing apparatus 100 according to the present embodiment.

  As shown in FIG. 4, the front conveyance line B includes a forming unit 106 that forms the sheet S using at least a part of the defibrated material. The forming unit 106 includes at least a depositing unit 60, a web forming unit 70, and a sheet forming unit 80. More specifically, in the front conveyance line B, the mixing unit 50 that mixes the first defibrated material sent from the rear conveyance line A by the blower 56 is on the machine base 150e near the center of the apparatus main body 150 in the width direction. The stacking unit 60 is disposed above the mixing unit 50 on the third side wall 150c side, and the web W and the sheet S are formed from the bottom of the stacking unit 60 to the fourth side wall 150d side and conveyed. Along the conveyance direction of the web W and the sheet S, the web forming unit 70, the humidity control unit 78, the sheet forming unit 80, and the cutting unit 90 are arranged in this order from the bottom of the stacking unit 60.

  The discharge unit 96 is disposed outside the apparatus main body 150 and adjacent to the fourth side wall 150d, and receives the sheet S discharged from the discharge opening 154 opening in the fourth side wall 150d. For the same reason as the supply unit 10, the discharge unit 96 is preferably arranged as low as possible in the sheet manufacturing apparatus 100. This is because a paper jam may occur during paper discharge.

  The deposition part 60 and the web forming part 70 are arranged on the third side wall 150c side, and the discharge part 96 is arranged on the fourth side wall 150d side, so that the length in the apparatus main body 150 from the third side wall 150c to the fourth side wall 150d is increased. The entire direction can be used for forming the web W and the sheet S.

  As shown in FIGS. 2 and 4, the sheet manufacturing apparatus 100 of this embodiment includes a removal member insertion port 156 and a removal member discharge port 158 for inserting a removal member 200 described later. The removal member insertion port 156 is provided on one end side (the third side wall 150 c side) of the housing (apparatus main body 150) of the sheet manufacturing apparatus 100. In this example, the removal member insertion port 156 is an opening provided in the third side wall 150c, and is opened at a position where the removal member 200 can be placed on the mesh belt 72 from the outside. The removal member discharge port 158 is provided on the other end side (the fourth side wall 150 d side) of the housing (apparatus main body 150) of the sheet manufacturing apparatus 100. In this example, the removal member discharge port 158 is an opening provided in the fourth side wall 150d, and is open to a position where the removal member 200 inserted into the sheet manufacturing apparatus 100 can be taken out.

  As described above, the sheet manufacturing apparatus 100 according to the present embodiment has a configuration in which the sheet S is formed from the configuration in which the raw material for forming the sheet S is the web W in the front conveyance line B (mesh belt 72) (sheet formation). Since the forming portion 106 is arranged in a straight line up to the portion 80), the removing member 200 can be inserted and discharged (inserted) without being bent in the sheet manufacturing apparatus 100. Moreover, since the raw material is in the state of the web W or the sheet S in the conveyance line B, it is a conveyance unit that conveys the deposit (web W) or the sheet S, and the removal member 200 is efficiently inserted into the conveyance unit. can do.

Furthermore, in the sheet manufacturing apparatus 100 of the present embodiment, the stacking unit 60 is located on the side close to the removal member insertion port 156, and the forming unit 106 is located on the side close to the removal member discharge port 158. Therefore, by inserting the removal member 200, it is possible to make contact with most members on the conveyance path for conveying the deposit (web W) or the sheet S.

  In the example shown in the figure, both the removal member insertion port 156 and the removal member discharge port 158 are openings provided in the side wall, but a cover or a lid may be provided in the opening. Furthermore, although not shown, the removal member insertion port 156 and / or the removal member discharge port 158 may be provided with a roller or the like that moves with the removal member 200 interposed therebetween. Further, a sensor for detecting the removing member 200 may be provided in the vicinity of the opening or on the roller, and the sheet manufacturing apparatus 100 may be operated in the cleaning mode based on a signal from the sensor.

  In the sheet manufacturing apparatus 100 of the present embodiment, the removal member discharge port 158 is provided, but the removal member discharge port 158 is not an essential configuration. For example, even if the discharge unit 96 also serves as the removal member discharge port 158. Alternatively, when the removal member 200 is inserted, the discharge portion 96 may be separated from the apparatus main body 150 and the discharge opening 154 may be used as the removal member discharge port 158. As will be described later as a modification, when the removal member 200 is provided in the sheet manufacturing apparatus 100 or when the removal member 200 is inserted from the removal member discharge port 158, the removal member insertion port 156 may not be an essential configuration. is there.

  The operation unit 141 is located above the central region of the first side wall 150a on the front side of the apparatus main body 150, and is disposed at a position that is easy for an operator who operates the sheet manufacturing apparatus 100 to access. The operation unit 141 is disposed on the first side wall 150a omitted in FIG. 4 and includes, for example, a display unit that indicates various processing conditions and the state of each processing unit, and an input unit through which an operator inputs various conditions.

  In addition, in said example, although it was a dry aspect, the wet aspect may be sufficient as the sheet manufacturing apparatus which concerns on this invention. For example, a disaggregation unit (pulper) may be used instead of the defibrating unit 20, a deinking tool may be used instead of the classification unit 30, and a papermaking unit may be used instead of the sheet forming unit 80.

  Further, the sheet S manufactured by the sheet manufacturing apparatus according to the present invention mainly refers to a sheet shape. However, it is not limited to a sheet shape, and may be a board shape or a web shape. The sheet in this specification is divided into paper and non-woven fabric. The paper includes a mode in which pulp or used paper is used as a raw material and is formed into a thin sheet, and includes recording paper for writing and printing, wallpaper, wrapping paper, colored paper, drawing paper, Kent paper, and the like. Non-woven fabrics are thicker or lower in strength than paper, such as general non-woven fabrics, fiber boards, tissue paper (cleaning tissue paper), kitchen paper, cleaners, filters, liquid (waste ink and oil) absorbers, sound absorbing materials, Insulating materials, cushioning materials, mats, etc. The raw material may be plant fibers such as cellulose, chemical fibers such as PET (polyethylene terephthalate) and polyester, and animal fibers such as wool and silk.

4). Cleaning of the sheet manufacturing apparatus The sheet manufacturing apparatus 100 of the present embodiment may be driven in a cleaning mode in which the inside of the apparatus is cleaned by inserting the removal member 200 in addition to the operation mode in which the normal sheet S is manufactured. it can.

In the sheet manufacturing apparatus 100 of the present embodiment, the substance removed from the apparatus by the removing member 200 is mainly an attached matter attached to the above-described transport unit, for example, fiber powder that has fallen off from the web W or the sheet S, Resin (additive) powder. The removal member 200 may remove other deposits. If fiber powder, resin (additive) powder, or the like dropped from the web W or sheet S adheres to the transport path, the transport performance may be reduced. The conveyance performance can be recovered to a good state.

4.1. Removal member As the removal member 200, for example, a cleaning sheet that is passed through a paper conveyance path of various recording apparatuses such as an ink jet printer and removes dirt adhered to a paper conveyance system member such as a paper feed roller and a paper discharge roller. Can be illustrated.

  FIG. 5 schematically shows a state where the removal member 200 is inserted into the sheet manufacturing apparatus 100. In the example of FIG. 5, the insertion path 200 a through which the removal member 200 is inserted is drawn with a one-dot chain line. The insertion path 200a extends from the removal member insertion port 156 onto the mesh belt 72 and continues to the removal member discharge port 158 through the pressurizing unit 81, the heating unit 83, and the cutting unit 90. In the example of FIG. 5, the removal member 200 inserted on the mesh belt 72 from the removal member insertion port 156 is conveyed along the insertion path 200a and is sandwiched between the pressure rollers 85 of the second pressure unit 81b. In addition, a state in which the first binding portion 82 is nipped by the heating roller 86 and moved to the position is depicted. A plurality of removal members 200 may be inserted continuously into the sheet manufacturing apparatus 100, but if at least one of the removal members 200 is inserted, the inside of the apparatus can be cleaned.

  The length of the removal member 200 in the conveyance direction (the direction along the insertion path 200a of the removal member 200) may be longer than the length from the removal member insertion port 156 to the removal member discharge port 158, or by the sheet manufacturing apparatus 100. It may be the same length as the sheet S to be manufactured, or may be longer or shorter than the sheet S. For example, the removing member 200 may have a single-cut shape as the A4 paper size. However, the length of the removal member 200 is the length from the removal member insertion port 156 to the mesh belt 72, and the length from the pressure roller 85 of the second pressure unit 81b to the heating roller 86 of the first binding unit 82. And it is preferable that the length from the heating roller 86 of the 2nd binding part 84 to the removal member discharge port 158 is longer. In this way, since the driving force for moving the removing member 200 is not interrupted in the sheet manufacturing apparatus 100, for example, it is possible to prevent the removing member 200 from stopping in the sheet manufacturing apparatus 100. Moreover, it is preferable that the length of the removal member 200 in the conveyance direction is longer than the sheet S to be manufactured from the viewpoint of suppressing a conveyance failure during insertion.

  The width of the removing member 200 is preferably the same as the width of the pressure roller 85, the heating roller 86, and the mesh belt 72, but may have a narrower width if necessary, and insertion and conveyance may be performed. It may be wider as possible. Further, the thickness of the removing member 200 is not particularly limited, but it is preferable that the thickness is larger than the thickness of the sheet S because pressure is applied more in contact with the conveyance unit.

  The configuration of the removing member 200 is not limited as long as the deposit on the transport unit can be removed. For example, the fabric (fabric), leather, film, paper, and those having an appropriate configuration added to the surface thereof, And so on.

  Hereinafter, as an example of the removing member 200, a sheet-like support having an elastic cleaning layer on one surface and a powder coating layer on the other surface will be described. The removing member 200 may have an adhesive layer on at least a part of the surface.

  The support for the removal member 200 preferably has a certain degree of hardness. In order to remove dirt (fibers, etc.) adhering to the members of the conveying unit by inserting the removing member 200, it is preferable that the target conveying unit is closely adhered to the removing member 200 and buried to some extent. When an elastic cleaning layer is formed on the surface of the support, the conveying unit can be brought into close contact with and buried in the elastic cleaning layer, and the deposit removal efficiency may be improved.

  Examples of the material for forming the support include films such as polyethylene, polypropylene, polystyrene, and polyethylene terephthalate, sheet-like plastic substrates, paper, nonwoven fabric, and resin-coated paper. Among these, a sheet-like plastic substrate, particularly a polyethylene terephthalate film, is particularly suitable as a support forming material.

The elastic cleaning layer provided on one surface of the support is a layer that directly contacts a roller or the like that is a cleaning target of the removing member 200 and scrapes off adhering matter to the component. Specifically, the elastic cleaning layer has a hardness defined by JIS K6400-2 of, for example, 20 to 50 (N / 314 cm ² ). The thickness of the elastic cleaning layer is preferably 10 to 100 μm.

  Examples of the material for forming the elastic cleaning layer include foam. Examples of the foam include a polyurethane foam having a self-foaming property (polyurethane foam). Besides this, rubber, polyvinyl chloride, ethylene-vinyl acetate copolymer, olefin resin, styrene resin, and the like. It is also possible to use a foam composed of a resin having no self-foaming property. Among these foams, polyurethane foam is suitable as a material for forming the elastic cleaning layer. In addition to polyols, chain extenders, polyisocyanate compounds, catalysts, and foaming agents (water), polyurethane foams can be added with foam stabilizers, crosslinking agents, pigments, antioxidants, yellowing inhibitors, etc. It can be obtained by mixing agents and reacting them to control the degree of soft and hard segments that form the polyurethane foam. Specifically, for example, a polyol component and a polyisocyanate compound, which are premixed and stirred with a polyol, a chain extender, a catalyst, a foaming agent, an additive, etc., are mixed and stirred by a molding machine and injected into a mold. And a foaming method.

  When the above-mentioned foam is used as the elastic cleaning layer, a separately manufactured foam is bonded and fixed to the support with an adhesive or the like. Thus, an elastic cleaning layer made of the foam can be formed.

  A powder coating layer may be provided on the other surface of the support. The powder coating layer can function as an anti-slip layer that prevents the removing member 200 from slipping due to frictional force, for example, when the surface of a driven roller or the like is rubbed with an elastic cleaning layer. The powder coating layer contains a powder and a binder. The thickness of the powder coating layer is preferably 0.1 to 5 μm. Examples of the powder include silica, alumina, calcium carbonate, magnesium carbonate, barium sulfate, aluminum oxide, aluminum hydroxide, kaolin, talc, clay, calcined clay, satin white, aluminum silicate, magnesium silicate, titanium dioxide, and zinc oxide. In addition to inorganic pigments such as diatomaceous earth, organic pigments such as acrylic resins, polyolefin resins, microcapsules, urea resins, and melamine resins can be used. In this invention, these 1 type may be used independently and 2 or more types may be used together. Among these, silica is particularly excellent in the anti-slip effect and durability (hardness), and is suitable for the powder coating layer.

  Examples of the binder contained in the powder coating layer together with the powder include starches such as oxidized starch and esterified starch, cellulose derivatives such as carboxymethylcellulose and hydroxyethylcellulose, polyvinyl alcohol and derivatives thereof, polyvinylpyrrolidone, and casein. , Gelatin, soybean protein, styrene-acrylic resin and derivatives thereof, styrene-butadiene latex, acrylic emulsion, vinyl acetate emulsion, vinyl chloride emulsion, urethane emulsion, urea emulsion, alkyd emulsion and derivatives thereof. A seed may be used independently and two or more sorts may be used together. Among these, polyvinyl alcohol and derivatives thereof are particularly excellent as a powder fall-off preventing performance and are suitable as a binder constituting the powder coating layer.

  When a powder coating layer is employed, a coating liquid containing the above components is prepared, and this coating liquid is coated on a support using a known coating method and dried. can do.

  The removing member 200 may have an adhesive portion on a part of its surface. When the adhesive part comes into contact with a conveying part (for example, a roller) on which foreign matter such as dust such as fiber powder or resin powder or foreign matter adheres to the surface, the foreign substance adheres to itself with adhesive force. Even if such a pressure-sensitive adhesive portion is provided on the removing member 200, the deposits can be removed from the object surface.

4.2. Insertion of Removal Member The sheet manufacturing apparatus 100 of the present embodiment has at least a manufacturing mode for manufacturing the sheet S as described above and a cleaning mode for cleaning the inside of the apparatus by the removal member 200. The sheet manufacturing apparatus 100 may have other modes. The removing member 200 is inserted while the sheet manufacturing apparatus 100 is driven in the cleaning mode. The cleaning mode is a mode in which deposits are removed by the removal member 200, and includes a conveying operation in which the removal member 200 is inserted from the removal member insertion port 156 and discharged from the removal member discharge port 158. Therefore, in the cleaning mode, the mesh belt 72 and the rollers of the sheet forming unit 80 may be driven, and other configurations may be controlled to stop. In the cleaning mode, heating of the heating roller 86 may be stopped. In the cleaning mode, the heating roller 86 may be heated as long as the function of the removing member 200 is not impaired, and the function of the removing member 200 is not impaired even for other configurations (for example, the suction mechanism 76). It may be driven by. The cleaning mode is a mode in which each component is operated in a mode different from the manufacturing mode, and is performed in a state where the sheet S is not manufactured (before or after manufacture). In the cleaning mode, the removal member 200 can be transported and other driving units can be prevented from moving, so that, for example, energy consumption can be suppressed.

  The conveyance speed of the removing member 200 in the cleaning mode may be slower than the conveyance speed of the web W or the sheet S in the manufacturing mode for manufacturing the normal sheet S. By doing in this way, the time which the removal member 200 contacts each structure of a conveyance part can be lengthened, and the removal efficiency of a deposit | attachment may improve.

  In the sheet manufacturing apparatus 100 of the present embodiment, cleaning is performed by inserting the removal member 200 at an appropriate timing. For example, by notifying the user of information regarding the operating time of the sheet manufacturing apparatus 100 and / or information regarding the number of sheets S and the number of input raw materials, the user can insert the removal member 200. Also good. Such notification can be performed by, for example, the sheet manufacturing apparatus 100 including a notification unit.

  As a mode of notification performed by the notification unit, for example, prompting the user to insert the removal member 200 by sound, light, display, or the like can be cited. Such a notification unit is, for example, a buzzer, a lamp (LED or the like), a display panel, and the like, and can be appropriately provided in the apparatus main body 150 or the operation unit 141. The notification unit is controlled by the control unit 140.

  The information related to the operating time includes, for example, the time during which the sheet S is manufactured by the sheet manufacturing apparatus 100, and the number of rotations of at least one roller (information corresponding to the operating time of the apparatus can be obtained from the number of rotations). Further, the information regarding the number of sheets S and the number of input raw materials includes the number of manufactured sheets S and the number of used paper used when used paper is used as a raw material. And it can instruct | indicate that the control part 140 generate | occur | produces or acquires such information, and the control part 140 notifies a notification part based on the information concerned.

If the timing of cleaning is notified to the user in this way, the user can be released from management such as periodic cleaning and checking of deposits, and deposits can be more reliably removed. Thereby, the conveyance performance of the web W or the sheet | seat S can be maintained in a favorable state. When the cleaning mode is activated when the user is notified, if the removal member 200 is not inserted from the removal member insertion port 156 by the user, energy is wasted. You may make it wait for the input to the effect that preparation for insertion is completed. Furthermore, from this point of view, a sensor that determines whether or not the removal member 200 is inserted into the removal member insertion port 156 may be provided, and the cleaning mode may be activated according to the detection result of the sensor. Furthermore, a folding tray for inserting the removal member 200 from the correct position may be provided in the sheet manufacturing apparatus 100, and the cleaning mode may be activated by detecting that the tray has been set.

  The sheet manufacturing apparatus 100 may be configured so that the user can perform cleaning at an arbitrary timing. For example, you may comprise the operation part 141 so that the instruction | indication (input for a user performing cleaning) in the cleaning mode can be performed. By such a command (input), the operation of the transport unit in the cleaning mode may be started and the removal member 200 may be inserted. In this way, the sheet manufacturing apparatus 100 can be cleaned at the user's discretion.

5. In the above embodiment, the removal member 200 is inserted from the removal member insertion port 156 and discharged from the removal member discharge port 158. However, the removal member 200 is wound into a folded shape or a roll shape. You may arrange | position in the sheet manufacturing apparatus 100 with the shape formed. In this case, for example, the removal member 200 may be placed on the mesh belt 72 and discharged from the removal member discharge port 158 by activation of the cleaning mode by the user. Furthermore, the removing member 200 to which the adhered matter does not necessarily have to be discharged from the sheet manufacturing apparatus 100, may be wound and collected in the sheet manufacturing apparatus 100, for example. In this case, the removal member discharge port 158 is unnecessary, and a roller for winding is installed in the sheet manufacturing apparatus 100. Furthermore, the recovered removal member 200 may be used a plurality of times.

  If the removal member 200 can be easily distinguished from the sheet S, it can be determined even if it is mixed with the sheet S that is normally manufactured. In such a case, the removal member 200 may be discharged to the discharge unit 96 in the same manner as the sheet S. In this case, the removal member discharge port 158 is unnecessary, and the removal member 200 can be recovered from the discharge portion 96. Further, the discharge unit 96 may be configured to be detachable from the apparatus main body 150, and the removal member 200 may be discharged from the discharge opening 154. The removal member 200 may be cut and discharged by the cutting unit 90 in the same manner as the sheet S.

  In the above embodiment, the mesh belt 72 and the sheet forming unit 80 are cleaned by the removing member 200. However, any one of the mesh belt 72 and the sheet forming unit 80 can be obtained by appropriately changing the arrangement of the components. It is good also as an aspect which cleans one side.

  In the above embodiment, the removal member 200 is inserted from the removal member insertion port 156. However, the removal member 200 is inserted from the removal member discharge port 158 by reversing the conveying direction of the removal member 200 in the insertion path 200a. And you may discharge | emit from the removal member insertion port 156. FIG. In this case, the mesh belt 72, the rollers of the sheet forming unit 80, and the like may be rotated in the opposite direction to the case where the sheet S is manufactured (forward direction). Further, the removal member 200 may be inserted from the removal member insertion port 156 and discharged from the removal member insertion port 156. Similarly, the removal member 200 may be inserted from the removal member discharge port 158 and discharged from the removal member discharge port 158.

In addition, the mesh belt 72, the rollers of the sheet forming unit 80, and the like may be inserted through the removal member 200 while appropriately changing the forward and reverse rotations in the cleaning mode. For example, the removal member 200 is gradually moved downstream in the conveyance direction by making the forward movement distance (movement distance downstream in the conveyance direction) of the belt or roller longer than the backward movement distance (movement distance upstream in the conveyance direction). You may make it convey to. If the reciprocating motion is small, the deposit removal efficiency may be improved.
