FIG. 2 is a configuration diagram showing a schematic configuration of the paper recycling apparatus 100 provided in the paper recycling printing system 1000 according to the present embodiment. As shown in FIG. 2, the paper recycling apparatus 100 includes a control unit 120, a used paper supply unit 100a, and a manufacturing unit 110 as a paper recycling unit. The manufacturing unit 110 manufactures the printed recycled paper Pr1 or the recycled paper Pr2. The manufacturing unit 110 includes a crushing unit 10, a defibrating unit 20, a sorting unit 30, a first web forming unit 40, a rotating body 45, a mixing unit 50, a depositing unit 60, and a second web forming unit. 70, a sheet forming unit 80, and a cutting unit 90.

The used paper supply unit 100 a supplies the used paper Pu to the crushing unit 10. The used paper supply unit 100a is, for example, an automatic input unit for continuously inputting used paper Pu to the crushing unit 10. The used paper Pu supplied by the used paper supply unit 100a is not limited to used paper, and may be any paper including fibers such as pulp sheets.

The crushing unit 10 cuts the used paper Pu supplied by the used paper supply unit 100a into pieces by cutting in the air. The shape and size of the strip is, for example, a strip of several cm square. In the illustrated example, the crushing unit 10 has a crushing blade 11, and the charged raw material can be cut by the crushing blade 11. As the crushing part 10, a shredder can be used, for example. The used paper Pu cut by the crushing unit 10 is received by a hopper 21 provided in the defibrating unit 20 and then transferred (conveyed) to the defibrating device unit 23 through the tube 22.

The defibrating device unit 23 defibrates the raw material cut by the crushing unit 10. Here, “defibrating” in the present specification refers to unwinding the used paper Pu as a material to be defibrated formed by binding a plurality of fibers into one fiber. The defibrating device section 23 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.

The material that has passed through the defibrating device 23 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 defibrating unit 23 performs defibrating in a so-called dry method in the atmosphere (in the air) without using a solvent, water, or the like. Specifically, an impeller mill is used as the defibrating device unit 23. The defibrating device unit 23 has a function of generating an air current that sucks the raw material and discharges the defibrated material. Thereby, the defibrating apparatus unit 23 can suck the raw material together with the airflow from the introduction port 23a by the airflow generated by itself, defibrate, and transport the defibrated material to the discharge port 23b. The defibrated material that has passed through the defibrating device unit 23 is transferred to the sorting unit 30 via the pipe 31. In addition, as the airflow for transporting the defibrated material from the defibrating device unit 23 to the sorting unit 30, an airflow generated in the defibrating device unit 23 may be used, or an airflow generating device such as a blower is provided, Airflow may be used.

The sorting unit 30 introduces the defibrated material defibrated by the defibrating unit 20 through the pipe 31 into the sorting device unit 33 from the introduction port 32 and sorts the defibrated material according to the length of the fiber. As the sorting device unit 33, for example, a sieve is used. The sorting device section 33 has a net (filter, screen), fibers or particles smaller than the mesh size of the mesh (one that passes through the mesh, the first sort), and fibers larger than the mesh size of the mesh. And undefibrated pieces and lumps (those that do not pass through the net, second sort). For example, the first selection is transferred to the mixing unit 50 via the pipe 44. The second selected item is returned to the defibrating unit 20 from the discharge port 34 via the pipe 35. Specifically, the sorting device unit 33 is a cylindrical sieve that is rotationally driven by a motor. As the net of the sorting unit 33, 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.

1st web formation part 40 conveys the 1st sorting thing which passed sorting part 30 to mixing part 50. The first web forming unit 40 includes a mesh belt 41, a stretching roller 42, and a suction unit (suction mechanism) 43.

The suction unit 43 can suck the first sorted material dispersed in the air through the opening (opening of the mesh) of the sorting unit 30 onto the mesh belt 41. The first sorted matter is sucked from the sorting unit 30 by the suction unit 43 and is deposited on the moving mesh belt 41 to form the web V. The basic configuration of the mesh belt 41, the stretching roller 42, and the suction unit 43 is the same as the mesh belt 71, the stretching roller 72, and the suction unit (suction mechanism) 73 of the second web forming unit 70 described later. .

The web V is formed in a soft and swelled state with a lot of air by passing through the sorting unit 30 and the first web forming unit 40. The web V deposited on the mesh belt 41 is put into the pipe 44 and conveyed to the mixing unit 50.

The rotating body 45 can cut the web V before the web V is conveyed to the mixing unit 50. In the illustrated example, the rotator 45 includes a base 45a and a protrusion 45b protruding from the base 45a. The protrusion 45b has, for example, a plate shape. In the illustrated example, four protrusions 45b are provided, and the four protrusions 45b are provided at equal intervals. When the base 45a rotates in the direction R, the protrusion 45b can rotate around the base 45a. By cutting the web V by the rotating body 45, for example, it is possible to reduce fluctuations in the amount of defibrated material per unit time supplied to the deposition unit 60 described later.

The mixing unit 50 mixes the first sorted product that has passed through the sorting unit 30 and is conveyed by the first web forming unit 40 with the binder resin powder. The mixing unit 50 includes a powder supply device 51 that supplies the binder resin powder, a pipe 52 that conveys the first selected material and the binder resin powder, and a blower 53. The tube 52 is continuous with the tube 44.

In the mixing unit 50, an air stream is generated by the blower 53 and can be conveyed while mixing the first selected material and the binder resin powder supplied from the powder supply device 51 in the pipe 52. . The binder resin powder supplied from the powder supply device 51 includes a resin capable of binding a plurality of fibers. At the time when the resin is supplied, the plurality of fibers are not bound. The resin binds the plurality of fibers by melting when passing through a sheet forming portion 80 described later. Note that the mechanism for mixing the first selected product and the binder resin powder is not particularly limited.

The binder resin powder supplied from the powder supply device 51 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 as a mixture as appropriate.

The binder resin powder supplied from the powder supply device 51 includes, in addition to the resin that binds the fibers, a colorant for coloring the fibers and the fiber according to the type of the sheet to be manufactured. An aggregation inhibitor for preventing aggregation, a flame retardant for making fibers difficult to burn, and the like may be included. The mixture of the first selected product and the binder resin powder that has passed through the mixing unit 50 is transferred to the deposition unit 60 via the tube 54.

The deposition unit 60 introduces the mixture that has passed through the mixing unit 50 into the deposition device unit 62 from the introduction port 61, loosens the entangled fibers of the defibrated material, and lowers the fibers while dispersing them in the air. Furthermore, when the resin of the binder resin powder supplied from the powder supply device 51 is in a fibrous form, the deposition device unit 62 loosens the entangled resin fibers. Thereby, the deposition unit 60 can deposit the mixture on the second web forming unit 70 with good uniformity.

As the deposition unit 62, a cylindrical sieve having a rotating net is used, and fibers or particles contained in the mixture that has passed through the mixing unit 50 are smaller than the opening size of the mesh of the sieve, that is, fibers that can pass through the net. Or let the particles pass. The configuration of the deposition unit 60 is, for example, the same as the configuration of the sorting unit 30.

It should be noted that the “sieving” of the deposition device unit 62 may not have a function of selecting a specific object. In other words, the “sieving” used as the deposition apparatus unit 62 means that a net is provided, and all of the mixture introduced into the deposition apparatus unit 62 may be allowed to pass through.

The second web forming unit 70 deposits the passing material that has passed through the depositing unit 60 to form the web W. The second web forming unit 70 includes, for example, a mesh belt 71, a tension roller 72, and a suction unit (suction mechanism) 73.

The mesh belt 71 accumulates the passing material that has passed through the opening (opening of the mesh) of the accumulation unit 60 while moving. The mesh belt 71 is stretched by a stretching roller 72, and is configured to allow air to pass therethrough. The mesh belt 71 moves continuously as the stretching roller 72 rotates. The passing material that has passed through the accumulation unit 60 descends on the mesh belt 71 that moves continuously, whereby the web W is formed on the mesh belt 71.

The suction part 73 is provided below the mesh belt 71 (on the opposite side to the accumulation part 60 side). The suction unit 73 can generate an airflow directed downward (airflow directed from the accumulation unit 60 to the mesh belt 71). Thereby, the discharge speed | rate of the passing material from the deposition part 60 can be enlarged.

As described above, by passing through the deposition part 60 and the second web formation part 70 (web formation process), the web W in a soft and swelled state containing a large amount of air is formed. The web W deposited on the mesh belt 71 is conveyed to the sheet forming unit 80. In the illustrated example, a humidity control unit 74 that adjusts the humidity of the web W is provided. The humidity control unit 74 can add water or water vapor to the web W to adjust the quantity ratio of the web W to water.

The sheet forming unit 80 pressurizes and heats the web W deposited on the mesh belt 71 to form the sheet S. In the sheet forming unit 80, by applying heat to the mixture of the defibrated material and the binder resin powder mixed in the web W, a plurality of fibers in the mixture are bound to each other via the binder resin powder. Can be worn.

The sheet forming unit 80 includes a pressurizing unit 81 that pressurizes the web W and a heating unit 82 that heats the web W pressed by the pressurizing unit 81. The pressurizing unit 81 includes a pair of

calendar rollers

81 a and 81 b and applies pressure to the web W. The web W is pressed to reduce its thickness, and the density of the web W is increased. The heating unit 82 includes a pair of

heating rollers

82a and 82b. The sheet W is formed by heating the web W pressed by the

calendar rollers

81a and 81b by the

heating rollers

82a and 82b, melting the resin, and binding the fibers. Here, the pressure applied to the web W by the

calendar rollers

81 a and 81 b of the pressurizing unit 81 can be higher than the pressure applied to the web W by the

heating rollers

82 a and 82 b of the heating unit 82. The number of

calendar rollers

The cut single-sheet printed recycled paper Pr1 or recycled paper Pr2 is discharged to the recycled paper discharge section 100b also shown in FIG. 1, and is transported and stored in the recycled paper cassette 300 as the first storage section. Note that the paper recycling method is not limited to the above-described method, and for example, a method of physically removing a recording medium called toner attached to the surface of the recording medium may be used, or a so-called wet method. May be.

FIG. 3 is an external perspective view showing an example of a specific form of the printing apparatus 200. As shown in FIG. 3, a new paper cassette 310 is loaded in the first cassette loading section 200a provided in the printing apparatus 200, and a recycled paper cassette 300 is loaded in the second cassette loading section 200b. The In addition, illustration of the sheet | seat stored in cassette 300,310 to illustrate is abbreviate | omitted.

A new paper cassette 310 in which new paper Pn is stored or a recycled paper cassette 300 in which recycled paper Pr is stored is mounted in the printing apparatus 200, and predetermined printing is executed to obtain a printed matter Pp. When there is no storage paper in the new paper cassette 310 or the recycled paper cassette 300 selected during execution of printing, the new paper cassette 310 in which the new paper Pn is stored is newly purchased and prepared in advance by human hands. Printing can be resumed by replenishing the new paper cassette 310 with paper. However, in the paper recycling printing system 1000 according to the present embodiment, the recycled paper Pr to be replenished in the recycled paper cassette 300 is stored in the paper recycling apparatus 100 in which the recycled paper Pr formed (manufactured) by the paper recycling apparatus 100 is stored. The mounted recycled paper cassette 300 can be detached from the paper recycling apparatus 100 and mounted on the second cassette mounting portion 200b of the printing apparatus 200.

Accordingly, when there is no recycled paper Pr in the recycled paper cassette 300 attached to the printing apparatus 200, when the required amount of recycled paper Pr is not formed and stored in the recycled paper cassette 300 attached to the paper recycling apparatus 100, Printing is suspended until the required amount of recycled paper Pr is manufactured and the stored recycled paper cassette 300 is loaded into the printing apparatus 200. When the recycled paper Pr is manufactured in advance and held as stock, the empty recycled paper cassette Pr may be replenished with the recycled paper Pr in the same manner as the new paper Pn.

FIG. 4 is a cross-sectional view showing a schematic configuration of the recycled paper cassette 300 described above. The recycled paper cassette 300 shown in FIG. 4 is in a state of being mounted on the cassette mounting portion 100c of the paper recycling apparatus 100, and in this example, an optical sensor is used as the storage amount detection means. The storage amount detection means is not limited to an optical type, and known storage amount detection means such as a storage amount detection means using a lever provided with a microswitch can be used.

As shown in FIG. 4, the recycled paper Pr formed by the paper recycling apparatus 100 is discharged toward the recycled paper cassette 300 from the recycled paper discharge unit 100b. The recycled paper cassette 300 and the paper recycling apparatus 100 are configured with a first sensor S1 and a second sensor S2 as supply detection means for recycled paper Pr arranged to face each other.

When the recycled paper cassette 300 is mounted on the paper recycling apparatus 100, the first sensor S1 and the second sensor S2 are arranged in order from the recycled paper discharge unit 100b. The first sensor S <b> 1 includes a first light emitting unit 101 provided in the paper recycling apparatus 100 and a first light receiving unit 301 provided in the recycled paper cassette 300. Similarly, the second sensor S <b> 2 includes a second light emitting unit 102 provided in the paper recycling apparatus 100 and a second light receiving unit 302 provided in the recycled paper cassette 300.

The recycled paper Pr discharged toward the recycled paper cassette 300 passes through the detection area A of the first sensor S1 that is first disposed at a position close to the recycled paper discharge unit 100b. Accordingly, the sensor light L1 emitted from the first light emitting unit 101 is blocked by the recycled paper Pr, and the light blocking signal of the first light receiving unit 301 is stored in the storage unit 303 provided in the recycled paper cassette 300. The storage unit 300 includes a memory and a CPU. The CPU rewrites the storage amount stored in the memory based on the signals from the first sensor S1, the second sensor S2, and the maximum storage amount detection means. Then, the recycled paper Pr passes through the detection area B of the second sensor S2. Accordingly, the sensor light L2 emitted from the second light emitting unit 102 is blocked by the recycled paper Pr, and the light blocking signal of the second light receiving unit 302 is stored in the storage unit 303 provided in the recycled paper cassette 300.

In the storage unit 303, the recycled paper Pr is supplied to the recycled paper cassette 300 from the outside by receiving the light blocking signal from the first light receiving unit 301 first and then receiving the light blocking signal from the second light receiving unit 302. Judge that it was done. That is, the first sensor S1 and the second sensor S2 constitute a supply detection means for recycled paper Pr. Then, based on the supply detection information that the recycled paper Pr has passed by the first sensor S1 and the second sensor S2 as the supply detection means, the storage amount (storage) of the recycled paper Pr already stored in the storage unit 303 is stored. 1 (sheet) is added to (number of sheets). The first sensor S1 and the second sensor S2 may be reflective optical sensors.

The storage information including the storage amount information of the recycled paper Pr stored in the storage unit 303 is transmitted by the transmission unit 304 to the reception unit 104 included in the paper reproduction device 100 and stored in the control unit 105 of the paper reproduction device 100. The control unit 105 manufactures, for example, manufactures recycled paper Pr based on the acquired storage information including the storage amount information of the recycled paper Pr in the recycled paper cassette 300 and the recycled paper manufacturing instruction set in the paper recycling apparatus 100. Continuation, interruption, cancellation, etc. are controlled. Note that, in this example, wired transmission by connection between the external terminal 305 of the recycled paper cassette 300 disposed opposite to the external terminal 103 disposed in the cassette mounting unit 100c of the paper recycling apparatus 100 is illustrated. Information transmission by wireless communication between the transmission unit 304 and the reception unit 104 may be used. The transmission unit 304 is controlled by the CPU of the storage unit 300 and transmits the storage amount information to the reception unit 104 by serial communication. The receiving unit 104 is controlled by the control unit 105 and receives storage amount information from the transmission unit 304 by serial communication. The control unit 105 includes a memory and a CPU, and controls the paper reproducing device.

The recycled paper cassette 300 is preferably provided with a means for detecting the maximum storage amount of recycled paper Pr. As the maximum storage amount detection means, although not shown, a known mechanical sensor (for example, a lever + microswitch system) or an optical sensor can be used. When the maximum storage amount detection means detects that the recycled paper Pr supplied and stored in the recycled paper cassette 300 has reached the maximum storage amount, the storage amount information in the storage unit 303 is rewritten with the maximum storage amount information, and the transmission unit 304 further. As a result, the maximum storage amount information in which the maximum amount of recycled paper Pr is stored in the attached recycled paper cassette 300 is transmitted to the control unit 105 of the paper recycling device 100, and the paper recycling device 100 reproduces the recycled paper Pr. Supply to the paper cassette 300 is stopped.

By providing the maximum storage amount detection means, for example, when the recycled paper cassette 300 is loaded into the paper recycling apparatus 100, the recycled paper is directly refilled by a human hand, and stored in the storage unit 303. Even if a difference occurs between the stored amount and the actual stored amount, the stored amount stored in the storage unit 303 can be corrected to an accurate value when the maximum stored amount is reached. Further, it is possible to prevent the recycled paper Pr from being supplied to the recycled paper cassette 300 beyond the maximum storage amount.

FIG. 5 shows a state in which the recycled paper cassette 300 is attached to the printing apparatus 200. In a state where the recycled paper cassette 300 is mounted on the second cassette mounting portion 200b of the printing apparatus 200 illustrated in FIG. 5, the printing apparatus 200 includes the sensor light L3 toward the second light receiving unit 302 provided in the recycled paper cassette 300. Are provided, and a third light emitting unit 201 that emits the sensor light L4 toward the first light receiving unit 301 is provided. The third light emitting unit 201 and the second light receiving unit 302 constitute a third sensor S3, and the fourth light emitting unit 202 and the first light receiving unit 301 constitute a fourth sensor S4.

The third sensor S3 and the fourth sensor S4 are arranged with the fourth sensor S4 and the third sensor S3 in the order closer to the paper supply path 210c of the paper transport path 210 in a state of being mounted on the printing apparatus 200. Yes.

When the recycled paper cassette 300 in which the recycled paper Pr is stored is loaded in the printing apparatus 200 and a printing command selected using the recycled paper Pr as a recording medium is given to the printing apparatus 200, one sheet is taken out by the sheet take-out means 210b. Recycled paper Pr is discharged from the recycled paper cassette 300 toward the paper supply path 210c. Then, when the recycled paper Pr passes through the detection area C of the third sensor S3 first, the sensor light L3 emitted from the third light emitting unit 201 is blocked by the recycled paper Pr, and the second light receiving unit 302 The light blocking signal is stored in the storage unit 303 provided in the recycled paper cassette 300. Then, the recycled paper Pr passes through the detection area D of the fourth sensor S4. Thus, the sensor light L4 emitted from the fourth light emitting unit 202 is blocked by the recycled paper Pr, and the light blocking signal of the first light receiving unit 301 is stored in the storage unit 303 provided in the recycled paper cassette 300.

The storage unit 303 receives the light blocking signal from the second light receiving unit 302 first, and then receives the light blocking signal from the first light receiving unit 301, whereby the recycled paper Pr stored in the recycled paper cassette 300 is stored. It is determined that the recycled paper cassette 300 is supplied to the outside. That is, the third sensor S3 and the fourth sensor S4 constitute a carry-out detection unit for the recycled paper Pr. Based on the carry-out detection information that the recycled paper Pr has passed by the third sensor S3 and the fourth sensor S4 as the carry-out detection means, the storage amount (the number of stored sheets) of the recycled paper Pr stored in the storage unit 303 ) Is subtracted from 1 (sheet). The third sensor S3 and the fourth sensor S4 may be reflective optical sensors.

The storage information including the storage amount information of the recycled paper Pr stored in the storage unit 303 is transmitted to the reception unit 204 provided in the printing apparatus 200 by the transmission unit 304 and stored in the control unit 205 of the printing apparatus 200. The control unit 205 controls continuation, interruption, cancellation, etc. of printing based on the acquired storage information including the storage amount information of the recycled paper Pr in the recycled paper cassette 300 and the printing command set in the printing apparatus 200. The Further, when the storage amount of the recycled paper Pr is smaller than a predetermined amount, a warning for prompting the preparation of the recycled paper Pr can be displayed on the display unit of the printing apparatus 200 (not shown). As a result, the paper recycling apparatus 100 can be operated to produce a required amount of recycled paper Pr in advance, and printing is interrupted for a long time even when the recycled paper cassette 300 loaded in the printing apparatus 200 becomes empty. The recycled paper Pr can be replenished without any problems. In this example, wired transmission by connection between the external terminal 305 and the external terminal 203 arranged to face each other is illustrated, but information by wireless communication between the transmission unit 304 and the reception unit 204 is illustrated. It may be a transmission.

Further, it is preferable that the recycled paper cassette 300 is provided with a no-paper detecting means for detecting that the recycled paper Pr stored in the recycled paper cassette 300 attached to the printing apparatus 200 has run out. Although not shown in the drawing, a known mechanical sensor (for example, lever + microswitch system) or an optical sensor can be used as the paper absence detecting means.

When the sheet absence detecting means detects that there is no stored amount of recycled paper Pr in the recycled paper cassette 300, the storage amount information in the storage unit 303 is rewritten with no sheet information, that is, “0 sheets”, and the transmission unit 304 further prints the printing device. Information indicating no storage amount of the storage amount “0” of the recycled paper Pr is transmitted to the control unit 205 of 200, and printing is interrupted.

By providing the paper out detection means, even if a difference occurs between the storage amount of the recycled paper Pr stored in the storage unit 303 of the recycled paper cassette 300 and the actual storage amount of the recycled paper Pr, the paper is surely out of stock, Can be detected. Further, the storage amount stored in the storage unit 303 at that time can be corrected to an accurate value. As a case where there is a difference between the storage amount of the recycled paper Pr stored in the storage unit 303 and the actual storage amount of the recycled paper Pr, for example, the recycled paper Pr from the recycled paper cassette 300 attached to the printing apparatus 200 is used. For example, it may be taken out directly by a human hand.
