The setting unit 700 enables an operator (person) to input operation settings, and is a controller with a display device having a touch panel and the like. The setting unit 700 includes a CPU, a ROM, and a RAM. To control.

The storage unit 300 includes a paper storage unit 310 that stores new paper Pn, a first recycled paper storage unit 320 that stores printed recycled paper Pr1, and a second recycled paper storage unit that stores recycled paper Pr2. 330. In the paper recycling printing apparatus 1000 shown in FIG. 1, a paper storage unit 310 that stores new paper Pn, a first recycled paper storage unit 320 that stores printed recycled paper Pr1, and a second storage that stores recycled paper Pr2. Although the form provided with the recycled paper storage part 330 and one each is illustrated, it is not limited to this, You may provide multiple, respectively.

A recycled paper supply unit 200 is provided between the paper recycling unit 100 and the storage unit 300. The recycled paper supply unit 200 includes a recycled paper transport unit 210 (not shown in detail) and a first recycled paper supply unit as a first recycled paper supply unit that supplies the printed recycled paper Pr1 to the first recycled paper storage unit 320. 221 and a second recycled paper supply unit 222 as a second recycled paper supply unit that supplies the recycled paper Pr2 to the second recycled paper storage unit 330. Used paper Pu is fed into the paper recycling unit 100 from the used paper supply unit 100a provided in the paper recycling unit 100, and the regenerated printed recycled paper Pr1 or recycled paper Pr2 is recycled from the recycled paper discharge unit 100b to the recycled paper supply unit 200. It is delivered to the paper slot 210a.

The printed recycled paper Pr1 put into the recycled paper slot 210a is transported to the first recycled paper supply means 221 by the recycled paper transport means 210, and transported and stored in the first recycled paper storage section 320. The recycled paper Pr2 is transported to the second recycled paper supply means 222 by the recycled paper transport means 210, and is transported and stored in the second recycled paper storage unit 330. Whether the recycled paper loaded into the recycled paper slot 210a is the printed recycled paper Pr1 or the recycled paper Pr2 is determined by a determination unit (not shown) included in the setting unit 700, and the printed recycled paper Pr1 is loaded as described above. If it is determined that the recycled recycled paper Pr1 is conveyed to the first recycled paper storage unit 320 and the recycled paper Pr2 is determined to be loaded, the recycled paper Pr2 is transferred to the second recycled paper storage unit 330. It is conveyed to.

The determination unit outputs information for creating recycled paper (conditions for producing recycled paper) in the paper reproducing unit 100 input to the setting unit 700, for example, a production command (first condition) for printing recycled paper Pr1. In this case, it is determined that the printed recycled paper Pr1 is loaded into the recycled paper loading slot 210a, and the printed recycled paper Pr1 is conveyed to the first recycled paper supply means 221 via the recycled paper conveying means 210. It is stored in the first recycled paper storage unit 320. In addition, when the production command (second condition) for the recycled paper Pr2 is issued, the determination unit determines that the recycled paper Pr2 is loaded into the recycled paper insertion port 210a, and the recycled paper transporting unit. The recycled paper Pr <b> 2 is conveyed to the second recycled paper supply unit 222 via 210 and stored in the second recycled paper storage unit 330. The production command (first condition) for producing the printed recycled paper Pr1 is that the paper texture (the degree of fiber texture leveling), thickness, hardness / hardness, color, sheet characteristics, etc. are suitable for printing applications. It is a manufacturing condition which becomes a thing. Accordingly, the recycled paper (printed recycled paper Pr1) manufactured under the first condition and the recycled paper (recycled paper Pr2) manufactured under the second condition have a paper texture (degree of fiber texture leveling), thickness, Hardness / hardness, color, sheet characteristics, etc. are different.

The paper recycling printing apparatus 1000 includes a transport unit 400 between the storage unit 300 and the printing unit 500. The storage unit 300 includes a paper storage unit 310 that stores new paper Pn, and a first recycled paper storage unit 320 that stores printed recycled paper Pr1. Pr1 is taken out and conveyed to the printing unit 500. On the other hand, from the second recycled paper storage unit 330 that stores the recycled paper Pr2 that is not used for printing provided in the storage unit 300, the stored recycled paper Pr2 is directly taken out from the outside by, for example, an operator (person). .

As described above, the recycled paper Pr2 can be used in various forms, such as recycled paper that is used for printing by another printing machine, or paper for handwritten memos. Further, the paper recycling unit 100 described later is not limited to colorless (white) recycled paper, and can be colored in the paper recycling unit 100, so that colored recycled paper can be manufactured and printed. It can be provided for various uses other than printing, for example, for decoration purposes and for origami. Therefore, the recycled paper Pr2 is not supplied to the printing unit 500 provided in the paper recycling printing apparatus 1000, and a supply path to be supplied to the second recycled paper storage unit 330 that can be taken out from the outside is set.

The transport unit 400 includes a first take-out unit 411 that takes out a new paper Pn from the paper storage unit 310, and a second take-out unit 412 that takes out the printed recycled paper Pr1 from the first recycled paper storage unit 320. . The new paper Pn taken out by the first take-out means 411 or the printed recycled paper Pr1 taken out by the second take-out means 412 is transported to the paper supply section 400a of the transport section 400 by the transport means 420 not shown in detail. . The transport unit 420 of the transport unit 400 is configured to include, for example, a roller or a belt.

The transport unit 400 supplies a new paper Pn from the paper storage unit 310 or a printed recycled paper Pr1 from the first recycled paper storage unit 320 to the paper take-in unit 500a from the paper supply unit 400a. Is printed, and the printed material Pp is discharged from the printed material discharging unit 500b. The printed material Pp discharged from the printed material discharging unit 500b is discharged and stored in the printed material storage unit 600, and is taken out from the paper recycling printing apparatus 1000 by an operator (person). In this embodiment, the printing unit 500 and the printed material storage unit 600 are illustrated as independent configurations, but the printed material storage unit 600 may be integrated with the printing unit 500.

FIG. 2 is a configuration diagram showing a schematic configuration of the paper reproduction unit 100 provided in the paper reproduction printing apparatus 1000 according to the present embodiment. As shown in FIG. 2, the paper recycling unit 100 includes a used paper supply unit 100a, a manufacturing unit 110, and a control unit 120. 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 S 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

81a and 81b and

heating rollers

82a and 82b is not particularly limited.

The cutting unit 90 cuts the sheet S formed by the sheet forming unit 80. In the example shown in the figure, the cutting unit 90 cuts the sheet S in a direction parallel to the first cutting unit 91 that cuts the sheet S in a direction that intersects the conveyance direction of the sheet S, for example, a roller cutter or the like. A second cutting portion 92. The second cutting unit 92 cuts the sheet S that has passed through the first cutting unit 91, for example. By passing through the cutting unit 90, a single-size printed recycled paper Pr1 or recycled paper Pr2 cut from the sheet S is formed. The cut single-sheet printed recycled paper Pr1 or recycled paper Pr2 is discharged to the recycled paper discharge unit 100b also shown in FIG. Note that the paper recycling method is not limited to the above-described method, and various paper recycling methods such as a method of physically removing a recording medium called toner attached to the surface of the recording medium and a wet paper recycling method are available. Techniques can be employed.

The printed recycled paper Pr1 or recycled paper Pr2 manufactured by the paper recycling unit 100 described above is supplied to the first recycled paper storage unit 320 by the recycled paper supply unit 200 as described with reference to FIG. The recycled paper Pr2 is supplied to and stored in the second recycled paper storage unit 330. When the printing unit 500 selects the printed recycled paper Pr1 as the recording medium, the printed recycled paper Pr1 is taken out from the first recycled paper storage unit 320 by the transport unit 400, and a predetermined quantity is transported to the printing unit 500. The

FIG. 3 is a flowchart showing a flow of supplying the printed recycled paper Pr1 manufactured in the paper recycling unit 100 to the first recycled paper storage unit 320 or the recycled paper Pr2 to the second recycled paper storage unit 330.

(Printing section operation check)
When the paper reproducing unit 100 is started based on an instruction input to the setting unit 700, a printing unit operation confirmation step (S10) for confirming whether the printing unit 500 is in operation is executed. When the printing unit 500 is in the operating state, the printing operation based on the print command command received from the outside or instructed from the setting unit 700 is continued until the printing is completed without pausing. That is, when the printing unit 500 is in operation (YES), the paper reproduction unit 100 enters a standby state for starting the paper reproduction operation.

(Stop accepting external print instructions)
When the printing unit 500 has not received a print command command or when printing has been completed, that is, in the printing unit operation confirmation step (S10), it is confirmed that the printing unit 500 is not operating (NO). The printing unit 500 executes a print instruction reception stop step (S11) so as not to receive a print command. That is, it becomes what is called offline. As a result, the setting unit 700 displays a display such as “printing unit offline” or “printing cannot be performed because recycled paper is currently being manufactured” on a display unit (not shown), and is guided to an operator (person). .

(Recycled paper manufacturing)
When the printing unit 500 goes offline (S11), the paper recycling printing apparatus 1000 proceeds to a recycled paper manufacturing step (S12) for manufacturing recycled paper. In the recycled paper manufacturing step (S12), either the printed recycled paper Pr1 or the recycled paper Pr2 is manufactured from the used paper Pu by the setting of the setting unit 700 in the paper recycling unit 100 shown in FIG.

(Production recycled paper type judgment)
In the manufactured recycled paper type determining step (S13), the recycled paper manufactured in the recycled paper manufacturing (S12) step based on the setting information of the setting unit 700 is the printed recycled paper Pr1 used for printing or the playback not used for printing. In this step, the paper Pr2 is determined.

(Supply to the second recycled paper storage unit)
If it is determined in the manufactured recycled paper type determination step (S13) that the recycled paper manufactured by the paper recycling unit 100 is recycled paper Pr2 that is not subjected to printing, the recycled paper Pr2 is sent to the second recycled paper storage unit 330. Is supplied (S141).

(Confirmation of supply amount of second recycled paper storage unit)
When the recycled paper Pr2 is supplied to the second recycled paper storage unit 330 (S141), the number of manufactured recycled papers Pr2 set by the setting unit 700, that is, the recycled paper supplied to the second recycled paper storage unit 330. A supply amount confirmation step (S151) of the second recycled paper storage unit 330 is performed in which it is confirmed whether the amount of Pr2 is the number set by the setting unit 700. If the set quantity has not been reached (NO), the recycled paper manufacturing step (S12) is continued.

(Supply to the first recycled paper storage unit)
On the other hand, if it is determined in the manufactured recycled paper type determination step (S13) that the recycled paper manufactured by the paper recycling unit 100 is the printed recycled paper Pr1 used for printing, the printed recycled paper Pr1 is the first recycled paper. It is supplied to the storage unit 320 (S142).

(Confirmation of supply amount of first recycled paper storage unit)
When the printed recycled paper Pr1 is supplied to the first recycled paper storage unit (S142), the number of printed recycled paper Pr1 set by the setting unit 700, that is, the printing supplied to the first recycled paper storage unit 320 is printed. A supply amount confirmation step (S152) of the first recycled paper storage unit is performed in which it is confirmed whether the quantity of the recycled paper Pr1 is the number set by the setting unit 700. If the set quantity has not been reached (NO), the recycled paper manufacturing step (S12) is continued.

(Starts accepting external print instructions)
In the supply amount confirmation step (S151) of the second recycled paper storage unit or the supply amount confirmation step (S152) of the first recycled paper storage unit, the set number of recycled papers is the second recycled paper storage unit 330. Alternatively, when supplied to the first recycled paper storage unit 320 (YES), the offline state is canceled, and an external print instruction reception standby start step (S16) is executed, and the setting unit 700 or the printing unit 500 is informed. A display indicating that printing is possible is displayed. Then, the production of recycled paper in the paper recycling unit 100 stops.

Next, a flowchart of FIG. 4 shows a flow of transporting and supplying the new paper Pn stored in the storage unit 300 or the printed recycled paper Pr1 to the printing unit 500 to produce the printed material Pp.

(Print paper selection)
As shown in FIG. 4, printing is started based on print information when a control unit provided in the paper reproduction printing apparatus 1000 receives a print command command for starting printing. First, a printing paper selection step (S20) to be printed is executed. Based on the print command command or the print information, it is determined and selected whether the print paper is the print recycled paper Pr1 or the new paper Pn.

(First recycled paper storage unit storage amount confirmation)
If the printed recycled paper Pr1 is selected (YES) in the printed paper selection step (S20), it is confirmed whether the printed recycled paper Pr1 is stored in the first recycled paper storage unit 320 in which the printed recycled paper Pr1 is stored. A first recycled paper storage unit storage amount confirmation step (S21) is executed. If it is confirmed that at least one printed recycled paper Pr1 is stored (YES), the process proceeds to the next printed recycled paper take-out step (S22).

(Removal of printed recycled paper)
The printed recycled paper take-out step (S22) is a step in which the printed recycled paper Pr1 is taken out from the first recycled paper storage unit 320 and conveyed to the paper take-in unit 500a of the printing unit 500 by the conveying unit 400. The printing recycled paper Pr1 conveyed to the paper take-in section 500a is subjected to predetermined printing by the printing section 500, and is then discharged as a printed material Pp to the printed material discharge section 500b and stored in the printed material storage section 600 (S200). ) Is executed.

(Print quantity confirmation)
When the printing step (S200) is executed, a printing quantity confirmation step (S211) is executed to check whether the printing quantity based on the printing command has been reached. If the printing quantity based on the printing command has been reached (YES), printing is terminated. If the print quantity has not been reached (NO), the process proceeds to the first recycled paper storage unit storage amount confirmation step (S21), and printing on the printed recycled paper Pr1 is continued.

(Reselect printing paper)
In the step of the above-mentioned first recycled paper storage unit storage amount confirmation step (S21), when it is confirmed that the printed recycled paper Pr1 is not stored (NO), the printing paper reselection step (S23) is executed. . In the printing paper reselecting step (S23), it is selected whether to perform predetermined printing on either the new paper Pn or the printed recycled paper Pr1.

As a means for selection, an operator (person) determines from “printed recycled paper Pr1 remaining amount”, “decision of continuation or cancellation of printing”, and the like displayed on a display unit provided in the paper recycling printing apparatus 1000. In this example, it is assumed that printing is continued. In order to continue printing, printing is performed on a new paper Pn that can be easily replenished with paper to be printed (YES) or the new paper Pn is not selected (NO), and the paper recycling unit 100 selects the printed recycled paper Pr1. It is selected whether to continue printing through manufacture and storage in the first recycled paper storage unit 320.

When printing (YES) is selected on the new paper Pn in the printing paper reselecting step (S23), printing is performed based on the flow (NO) in the printing paper selection step (S20) described later, that is, the new paper Pn is selected. Will continue. On the other hand, when the new paper Pn is not selected (NO), a transition step (S24) to the production flow of the printed recycled paper Pr1 is executed based on the above-described recycled paper production flow shown in FIG.

At this time, as described in the recycled paper manufacturing flow shown in FIG. 3, the printing unit 500 is in an offline state and waits until the manufactured printed recycled paper Pr1 is stored in the first recycled paper storage unit 320. When the printed recycled paper Pr1 is stored in the first recycled paper storage unit 320, the process proceeds to the above-described printed recycled paper take-out step (S22). It should be noted that the production quantity of the printed recycled paper Pr1 is specified in the print command when the production quantity of the printed recycled paper Pr1 is designated to the setting unit 700 when (NO) is selected in the printing paper reselecting step (S23). There is no particular limitation as to whether or not the remaining amount of printing is produced with respect to the printed quantity.

On the other hand, if the print recycled paper Pr1 is not selected (NO) in the printing paper selection step (S20), the new paper Pn stored in the paper storage unit 310 is selected. When a new paper Pn is selected, a new paper storage amount confirmation step (S30) for confirming whether or not the new paper Pn stored in the paper storage unit 310 is stored is executed. In the new paper storage amount confirmation step (S30), when it is confirmed that the new paper Pn is stored (YES), the new paper Pn is taken out from the paper storage unit 310 (S31), and the new paper Pn is obtained. Supplied to the printing unit 500. Then, a printing step (S200) and a printing quantity confirmation step (S212) are executed.

In the new paper storage amount confirmation step (S30), if the new paper Pn is not stored in the paper storage unit 310 (NO), the operator (person) is warned by warning means (not shown) and the paper storage unit 310 is informed. The process proceeds to a step of waiting for a new sheet Pn to be replenished (S32). When new paper Pn is replenished to the paper storage unit 310, printing is resumed.

Note that when setting the other recycled paper storage unit (other first recycled paper storage unit) 32B, the recycled paper storage unit (first recycled paper storage unit) without the printed recycled paper Pr1 is not always selected. Absent. For example, a recycled paper storage unit (first recycled paper storage unit) that has already reached the maximum storage amount of the printed recycled paper Pr1 is excluded from the options, and the recycled paper storage unit that is empty without the printed recycled paper Pr1. In the absence of the (first recycled paper storage unit), even if the printed recycled paper Pr1 is stored, the recycled paper storage unit (the first recycled paper storage unit Pr1 having a region where the printed recycled paper Pr1 can be newly stored) Recycle paper storage unit). In the paper recycling printing apparatus 1000 exemplified in this embodiment, the recycled paper storage is performed such that the printed recycled paper Pr1 is supplied to the recycled paper storage unit (first recycled paper storage unit) 321 as shown in FIG. The device control unit (not shown) recognizes that the unit (first recycled paper storage unit) 321 is another recycled paper storage unit (other first recycled paper storage unit) 32B, and the storage unit switching means performs the first operation. Recycled paper supply means (recycled paper storage and supply means) 221 is driven to a position of a recycled paper storage section (first recycled paper storage section) 321.

(Recycled paper supply)
When another recycled paper storage unit (other first recycled paper storage unit) is set (S11), it is recycled to the set other recycled paper storage unit (other first recycled paper storage unit) 32B. The supply of the printed recycled paper (S12) is executed from the first recycled paper supply means (recycled paper storage and supply means) 221 of the paper supply unit 200.

(Detection of stored amount of recycled printed paper)
When the printed recycled paper Pr1 is supplied to the other recycled paper storage unit (other first recycled paper storage unit) 32B, the recycled paper in the other recycled paper storage unit (other first recycled paper storage unit) 32B. Storage amount detection (S13) is performed. In the print recycled paper storage amount detection (S13), if the maximum storage amount is not reached, that is, NO, the print recycled paper supply (S12) is performed again. However, when the maximum storage amount has been reached, that is, YES, the process proceeds to the next resetting (S14) of the other recycled paper storage unit (other first recycled paper storage unit).

(Resetting the other first recycled paper storage unit)
A recycled paper storage unit (first recycled paper storage unit) 321 illustrated in FIG. 12 in the present embodiment, which is set in another recycled paper storage unit (another first recycled paper storage unit) 32B, When the maximum storage amount of the printed recycled paper Pr1 is reached, the other recycled paper storage unit (the other first recycled paper storage unit) is reset (S14). That is, in the present embodiment, the recycled paper storage unit (predetermined first recycled paper storage unit) 32A from which the printed recycled paper Pr1 conveyed to the printing unit 500 described above is taken out (predetermined first recycled paper storage unit) 32A. Recycled paper storage unit (first recycled paper storage unit) 322 and other recycled paper storage unit (other first recycled paper storage unit) 32B that has reached the maximum storage amount of printed recycled paper Pr1 (first recycled paper storage unit) Recycled paper storage unit (first recycled paper storage unit) 323 and 324 except for the recycled paper storage unit (first recycled paper storage unit) 321 and the other recycled paper storage unit. It is determined whether or not (other first recycled paper storage unit) 32B can be set.

Not exclusively. For example, a printed recycled paper storage unit (first recycled paper storage unit) that has already reached the maximum storage amount of the printed recycled paper Pr1 is excluded from the options, and the printed recycled paper is empty without the printed recycled paper Pr1. In the absence of the storage unit (first recycled paper storage unit), even if the printed recycled paper Pr1 is stored, the recycled paper storage unit (the first recycled paper storage unit Pr1) having an area where the printed recycled paper Pr1 can be newly stored. 1 recycled paper storage unit). In the paper recycling printing apparatus 1100 exemplified in this embodiment, as shown in FIG. 16, the printing recycling is performed so that the printing recycled paper Pr1 is supplied to the printing recycled paper storage unit (first recycled paper storage unit) 821. A device control unit (not shown) recognizes that the paper storage unit (first recycled paper storage unit) 821 is another recycled paper storage unit (other first recycled paper storage unit) 32B, and is regenerated by the storage unit switching means. The paper supply means 720 is driven to the position of the printed recycled paper storage unit (first recycled paper storage unit) 821.

(Recycled paper supply)
When another recycled paper storage unit (other first recycled paper storage unit) is set (S51), it is recycled to another set recycled paper storage unit (other first recycled paper storage unit) 32B. Printing recycled paper supply (S52) is executed from the recycled paper supply means 720 of the paper supply unit 700.

(Detection of stored amount of recycled printed paper)
When the printed recycled paper Pr1 is supplied to the other recycled paper storage unit (other first recycled paper storage unit) 32B, the printing reproduction in the other recycled paper storage unit (other first recycled paper storage unit) 32B. Paper storage amount detection (S53) is performed. In the print recycled paper storage amount detection (S53), when the maximum storage amount is not reached, that is, NO, the print recycled paper supply (S52) is performed again. However, when the maximum storage amount is reached, that is, YES, the process proceeds to the next resetting (S54) of the other recycled paper storage unit (other first recycled paper storage unit).

(Resetting the other first recycled paper storage unit)
A print recycled paper storage unit (first recycled paper storage unit) 821 illustrated in FIG. 16 in the present embodiment, which is set in another recycled paper storage unit (another first recycled paper storage unit) 32B. When the maximum storage amount of the printed recycled paper Pr1 is reached, the other recycled paper storage unit (the other first recycled paper storage unit) is reset (S54). That is, in the present embodiment, the printed recycled paper storage unit set in the predetermined recycled paper storage unit (predetermined first recycled paper storage unit) 32A from which the printed recycled paper Pr1 conveyed to the printing unit 500 described above is taken out. (First recycled paper storage unit) 822 and other recycled paper storage unit (other first recycled paper storage unit) 32B, a printed recycled paper storage unit (first recycled paper storage unit Pr1 that has reached the maximum storage amount of printed recycled paper Pr1) Of the recycled paper storage unit) 821 and the printed recycled paper storage unit (first recycled paper storage unit) 823, 824 except for one printed recycled paper storage unit (first recycled paper storage unit) It is determined whether or not it can be newly set as the recycled paper storage unit (another first recycled paper storage unit) 32B.

If any of the printed recycled paper storage units (first recycled paper storage units) 823, 824 or one of them has a storage area for the printed recycled paper Pr1 (YES), another recycled paper storage unit (other The process proceeds to the setting (S51) of the first recycled paper storage unit), and the printed recycled paper Pr1 is stored in the newly set other recycled paper storage unit (another first recycled paper storage unit) 32B. However, if there is no storable area in any of the printed recycled paper storage units (first recycled paper storage units) 823, 824, that is, the maximum storage amount has been reached (NO), the recycled paper Pr2 not used for printing It is confirmed whether the paper reproduction printing apparatus 1100 has received a production instruction (S55). If no production instruction for the recycled paper Pr2 is received (NO), the paper reproduction unit 100 stops and the supply of the printed reproduction paper Pr1 is suspended. To do. On the other hand, if the paper recycling printing apparatus 1100 has received an instruction to manufacture recycled paper Pr2 (YES), the process proceeds to supply of recycled paper Pr2 not to be described later to the recycled paper storage unit (S60). .

When the process proceeds to the step of confirming the production instruction for the recycled paper Pr2 (S55) before the stop of the paper regeneration unit 100, not only the stop of the paper regeneration unit 100 by the above-described flow but also the following case The paper reproducing unit 100 stops. For example, when the scheduled amount of printing recycled paper Pr1 is input to the paper recycling unit 100 in advance to the control unit and reaches the scheduled molding amount, an instruction for manufacturing recycled paper Pr2 before the stop of the paper recycling unit 100 is issued. The process proceeds to the confirmation (S55) step, and the sheet reproducing unit 100 is stopped. Alternatively, when all of the used paper Pu as the raw material supplied to the used paper supply unit 100a has been consumed, the process proceeds to the step of confirming the production instruction for the recycled paper Pr2 (S55) before the stop of the paper recycling unit 100. The paper recycling unit 100 is stopped or paused until the used paper Pu is supplied again.

As described above, one of the plurality of print recycled paper storage units (first recycled paper storage units) 821, 822, 823, and 824 included in the printed recycled paper storage unit 820 is supplied with the printed recycled paper Pr1. Since the recycled paper storage unit (another first recycled paper storage unit) 32B is set, even if the paper recycling unit 100 is continuously operated, the printed recycled paper Pr1 formed by the paper recycling unit 100 is printed recycled paper. It can be supplied to any one of the storage units (first recycled paper storage units) 821, 822, 823, and 824 and can be stored.

That is, in the paper recycling unit 100 shown in FIG. 13 provided in the paper recycling printing apparatus 1100 according to the present embodiment, a plurality of printing reproductions are performed in the printing recycled paper storage unit 820 in order to obtain printing recycled paper Pr1 with more stable quality. A paper storage unit (first recycled paper storage unit) 821, 822, 823, and 824 is provided so that the paper recycling unit 100 can be operated continuously for a longer time.

Also, printing set in a predetermined recycled paper storage unit (predetermined first recycled paper storage unit) 32A from a plurality of printed recycled paper storage units (first recycled paper storage unit) 821, 822, 823, and 824 Printed recycled paper storage unit (first recycled paper storage unit) for supplying and storing printed recycled paper Pr1 from the printed recycled paper storage unit (first recycled paper storage unit) excluding the recycled paper storage unit (first recycled paper storage unit) 822 Set as another recycled paper storage unit (another first recycled paper storage unit) 32B (in the example of this embodiment, a printed recycled paper storage unit (first recycled paper storage unit) 821) as the recycled paper storage unit) By doing so, when the printed recycled paper Pr1 conveyed to the printing unit 500 is taken out, the supply of the printed recycled paper Pr1 from the paper recycling unit 100 can be prevented from being overlapped, so that the occurrence of jamming can be prevented. can do.

Next, a flow of the recycled paper Pr2 not used for printing formed in the paper recycling unit 100 being discharged to the recycled paper discharge unit (second recycled paper storage unit) 600 is shown in the flowchart of FIG.

As shown in FIG. 18, the flow of transporting and supplying the recycled paper Pr2 stored in the storage unit 800 in the paper recycling printing apparatus 1100 according to the present embodiment to the printing unit 500 and discharging the non-printed recycled paper Pr2 is as follows. First, the recycled paper Pr2 formed in the paper recycling unit 100 is supplied to the recycled paper storage unit 830 of the storage unit 800.

(Recycled paper storage amount confirmation)
A recycled paper storage amount confirmation (S70) is performed in which it is confirmed whether or not the designated amount of recycled paper Pr2 to be discharged is stored in the recycled paper storage unit 830 of the storage unit 800. If the designated amount of recycled paper Pr2 is stored in the recycled paper storage unit 830 (YES), the process proceeds to the next printing unit pass (S71).

(Passed by the printing department)
In the printing section passage (S71), the printing section 500 is allowed to pass, but at this time, printing is not performed. Then, the recycled paper Pr2 that is not printed is discharged to the printed material discharge unit 500b.

(Recycled paper Pr2 quantity confirmation)
Then, through the recycled paper Pr2 quantity confirmation (S72), it is confirmed whether or not the recycled paper Pr2 discharged to the printed material discharge section 500b in the printing section passage (S71) step has a designated quantity. When the designated quantity is not reached (NO), the process proceeds to the printing section passing (S71), and the process is repeated until the designated recycled paper Pr2 is discharged. However, when the designated quantity is reached (YES), the discharge of the recycled paper Pr2 to the printed material discharge unit 500b is stopped.

In the recycled paper storage amount confirmation (S70) described above, when the recycled paper Pr2 is not stored in the recycled paper storage unit 830 (NO), the recycled paper Pr2 is supplied to the recycled paper storage unit 830 until the designated quantity is reached. .
