The entire disclosures of Japanese Patent Application Nos. 2016-129815, 2016-151021, and 2017-120285 are hereby incorporated herein by reference.
The present invention relates to a paper sheet recycling and printing apparatus, a printing apparatus, and a paper sheet recycling apparatus.
Paper recycling has been widely generalized from the viewpoint of resource utilization, but in the past, industrial manufacturing of a recycled paper sheet from an accumulated waste paper sheet was employed. In recent years, however, a technique and apparatus for forming a document printed and discarded in a business office into a recycled paper sheet in a business office and inserting the recycled paper sheet as a printing paper sheet to a printing machine have been disclosed (refer to Japanese Unexamined Patent Application Publication Nos. 7-175384, 10-171318, and 2008-33034).
Each of the inventions disclosed in Japanese Unexamined Patent Application Publication Nos. 7-175384, 10-171318, and 2008-33034 is a combined apparatus that supplies a recycled paper sheet directly to a printing apparatus from an apparatus for recycling a paper sheet on which the printing is finished, that is, a so-called waste paper sheet, and recycling of the waste paper sheet and printing onto the recycled paper sheet can be continuously performed.
The method of recycling the waste paper sheet in the apparatuses disclosed in Japanese Unexamined Patent Application Publication Nos. 7-175384, 10-171318, and 2008-33034 manufactures a recording target medium on which new printing is possible by physically removing a recording medium which is called a toner that adheres to a surface of the recording target medium (paper sheet). Contrary to this, a small-sized apparatus has been suggested in which the waste paper sheet is pulverized to a fibrous form and a new paper sheet can be manufactured, but in this case, it is possible to stabilize the quality of the recycled paper sheet and obtain high productivity by continuously inserting the waste paper sheet to be inserted into a recycling step and by continuously operating the apparatus.
By the continuous operation of the above-described apparatus, the recycled paper sheets are continuously supplied from the recycling apparatus to a paper sheet tray and the like of the printing apparatus. Meanwhile, since the printing apparatuses are normally used intermittently, when the recycled paper sheets stored in the paper sheet tray are held by paper sheet pickup means for printing, substantially at the same time, there may be a case where the recycled paper sheet is supplied from the recycling apparatus to the paper sheet tray. In this case, there is a concern of occurrence of jamming caused by paper sheet complication of two paper sheets.
In addition, in the inventions disclosed in Japanese Unexamined Patent Application Publication Nos. 7-175384, 10-171318, and 2008-33034, the recycled paper sheet is supplied as a paper sheet for printing to the printing apparatus, but there is also a case where, for the use other than the printing, the recycled paper sheet, such as a recycled paper sheet to be supplied for the printing of another printing machine or a paper sheet for handwritten memo, is supplied as it is. At this time, in the inventions disclosed in Japanese Unexamined Patent Application Publication Nos. 7-175384, 10-171318, and 2008-33034, the recycled paper sheet recycled by the apparatus is stored in a paper sheet cassette or the paper sheet tray of a printing paper sheet supply section as a paper sheet for printing to the printing apparatus. Therefore, in a case of providing the recycled paper sheet for the use other than the printing, the printing apparatus is stopped, the paper sheet recycling apparatus is further stopped, and after this, the necessary quantity of the recycled paper sheets is taken out from the paper sheet cassette or the paper sheet tray. In other words, there is a problem that the printing apparatus or the paper sheet recycling apparatus is stopped, and the working efficiency remarkably deteriorates.
According to this, the printing apparatus or the paper sheet recycling apparatus is stopped, and the working efficiency remarkably deteriorates. Here, the present invention is to provide a paper sheet recycling and printing apparatus that prevents occurrence of jamming due to the paper sheet complication, can continuously operate a paper sheet recycling apparatus, and can manufacture a recycled paper sheet that is not to be supplied for printing while operating a printing apparatus.
The present invention has been made to solve at least a part of the above-described problems, and an object thereof is to obtain a paper sheet recycling and printing apparatus that can continuously operate a paper sheet recycling apparatus by storing a recycled paper sheet and can manufacture the recycled paper sheet that is not to be supplied for printing while operating a printing apparatus.

According to the above-described application example, the controls of the paper sheet recycling apparatus and the paper sheet recycling and printing system are performed by the setting section which sets the type of the paper sheet, that is, whether the recording target medium to be supplied for the printing is “new paper sheet” or “recycled paper sheet manufactured under the first condition”, or a print instruction, such as “perform the printing of a log mark or the like on the recycled paper sheet manufactured under the second condition”.
According to the paper sheet recycling apparatus of the above-described application example, the determining section performs determination based on the setting of the setting section.
According to the above-described application example, in the paper sheet recycling apparatus of this application example provided in the paper sheet recycling and printing system in which the recycled paper sheet is manufactured under a plurality of conditions different from each other by the paper sheet recycling section, based on the setting information of the manufactured recycled paper sheet set in the setting section, it is possible to transport the predetermined paper sheet including the recycled paper sheet to the storage section or the printed material storage section, and to store the paper sheet in the storage section or the printed material storage section.
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The storage section 300 includes a paper sheet storage section 310 in which the new paper sheet Pn is stored, a first recycled paper sheet storage section 320 in which the printing recycled paper sheet Pr1 is stored, and a second recycled paper sheet storage section 330 in which the recycled paper sheet Pr2 is stored. In addition, an aspect in which the paper sheet recycling and printing apparatus 1000 illustrated in
A recycled paper sheet supply section 200 is provided between the paper sheet recycling section 100 and the storage section 300. The recycled paper sheet supply section 200 includes recycled paper sheet transport means 210 (not illustrated in detail), first recycled paper sheet supply means 221 that serves as a first recycled paper sheet supply section which supplies the printing recycled paper sheet Pr1 to the first recycled paper sheet storage section 320, and second recycled paper sheet supply means 222 that serves as a second recycled paper sheet supply section which supplies the recycled paper sheet Pr2 to the second recycled paper sheet storage section 330. The waste paper sheet Pu is inserted into the paper sheet recycling section 100 from a waste paper sheet supply section 100a provided in the paper sheet recycling section 100, and the recycled printing recycled paper sheet Pr1 or recycled paper sheet Pr2 are delivered to a recycled paper sheet insertion port 210a provided in the recycled paper sheet supply section 200 from a recycled paper sheet discharge section 100b.
The printing recycled paper sheet Pr1 inserted into the recycled paper sheet insertion port 210a is transported to the first recycled paper sheet supply means 221 by the recycled paper sheet transport means 210 and is transported and stored in the first recycled paper sheet storage section 320. In addition, the recycled paper sheet Pr2 is transported to the second recycled paper sheet supply means 222 by the recycled paper sheet transport means 210 and is transported and stored in the second recycled paper sheet storage section 330. A determining section (not illustrated) provided in the setting section 700 determines whether the recycled paper sheet inserted into the recycled paper sheet insertion port 210a is the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2, and as described above, when it is determined that the printing recycled paper sheet Pr1 is inserted, the printing recycled paper sheet Pr1 is transported to the first recycled paper sheet storage section 320, and when it is determined that the recycled paper sheet Pr2 is inserted, the recycled paper sheet Pr2 is transported to the second recycled paper sheet storage section 330.
The determining section determines that the printing recycled paper sheet Pr1 is inserted into the recycled paper sheet insertion port 210a in a case where creation information (condition for manufacturing the recycled paper sheet) of the recycled paper sheet in the paper sheet recycling section 100 input into the setting section 700, for example, a manufacturing command (first condition) of the printing recycled paper sheet Pr1 is issued, and the printing recycled paper sheet Pr1 is transported to the first recycled paper sheet supply means 221 via the recycled paper sheet transport means 210 and stored in the first recycled paper sheet storage section 320. In addition, the determining section determines that the recycled paper sheet Pr2 is inserted into the recycled paper sheet insertion port 210a in a case a manufacturing command (second condition) of the recycled paper sheet Pr2 is issued, and the recycled paper sheet Pr2 is transported to the second recycled paper sheet supply means 222 via the recycled paper sheet transport means 210 and stored in the second recycled paper sheet storage section 330. The manufacturing command (first condition) for manufacturing the printing recycled paper sheet Pr1 is a manufacturing condition in which texture of the paper (degree of uniformity of the fiber structure), thickness, hardness and rigidity, color, sheet characteristics and the like are in a desired form appropriate for a printing use. Therefore, the recycled paper sheet (printing recycled paper sheet Pr1) manufactured under the first condition and the recycled paper sheet manufactured under the second condition (recycled paper sheet Pr2) have texture of the paper (degree of uniformity of the fiber structure), thickness, hardness and rigidity, color, sheet characteristics and the like which are different from each other.
The paper sheet recycling and printing apparatus 1000 is provided with a transport section 400 between the storage section 300 and the printing section 500. The new paper sheet Pn or the printing recycled paper sheet Pr1 is taken out by the transport section 400 from the paper sheet storage section 310 in which the new paper sheet Pn is stored, and the first recycled paper sheet storage section 320 in which the printing recycled paper sheet Pr1 is stored which are provided in the storage section 300, and is transported to the printing section 500. Meanwhile, from the second recycled paper sheet storage section 330 which is provided in the storage section 300 and in which the recycled paper sheet Pr2 that is not to be supplied for the printing is stored, for example, the operator (person) directly takes out the stored recycled paper sheet Pr2.
As described above, the recycled paper sheet Pr2 may be various forms, such as, a recycled paper sheet that is not to be supplied for the printing, for example, a recycled paper sheet to be supplied for the printing of another printing machine, or a paper sheet for handwritten memo. Further, in the paper sheet recycling section 100 to be described later, it is also possible to manufacture a color recycled paper sheet since coloring is possible in the paper sheet recycling section 100 not being limited to a colorless (white) recycled paper sheet, and it is possible to provide the recycled paper sheet not only for the printing but also for various uses other than the printing, such as decoration or origami. Accordingly, the recycled paper sheet Pr2 is not supplied to the printing section 500 provided in the paper sheet recycling and printing apparatus 1000, and a supply path to be supplied in the second recycled paper sheet storage section 330 which can be taken out from the outside is set.
The transport section 400 includes first taking-out means 411 for taking out the new paper sheet Pn from the paper sheet storage section 310 and second taking-out means 412 for taking out the printing recycled paper sheet Pr1 from the first recycled paper sheet storage section 320. The new paper sheet Pn taken out by the first taking-out means 411 or the printing recycled paper sheet Pr1 taken out by the second taking-out means 412 is transported to a paper sheet supply section 400a of the transport section 400 by transport means 420 (not illustrated in detail). The transport means 420 of the transport section 400 is configured of, for example, rollers and belts.
The transport section 400 supplies the new paper sheet Pn from the paper sheet storage section 310 or the printing recycled paper sheet Pr1 from the first recycled paper sheet storage section 320 to a paper sheet taking-in section 500a from the paper sheet supply section 400a, predetermined recording information is printed in the printing section 500, and the printed material Pp is discharged from a printed material discharge section 500b. The printed material Pp discharged from the printed material discharge section 500b is discharged and stored in the printed material storage section 600 and taken out from the paper sheet recycling and printing apparatus 1000 by the operator (person). In addition, in the present embodiment, the printing section 500 and the printed material storage section 600 are illustrated as independent configuration elements, but the printed material storage section 600 may be integrally configured in the printing section 500.
The waste paper sheet supply section 100a supplies the waste paper sheet Pu to the coarse crushing section 10. The waste paper sheet supply section 100a is, for example, an automatic inserting section for continuously inserting the waste paper sheet Pu to the coarse crushing section 10. The waste paper sheet Pu supplied by the waste paper sheet supply section 100a is not limited to the waste paper sheet, and may be any paper sheet containing fibers, for example, a pulp sheet.
In the coarse crushing section 10, the waste paper sheet Pu supplied by the waste paper sheet supply section 100a is cut into pieces by cutting in the air. The shape or size of the pieces is, for example, several cm square. In the example illustrated in the drawing, the coarse crushing section 10 has a coarse crushing blade 11, and the coarse crushing blade 11 can cut the inserted raw material. As the coarse crushing section 10, for example, a shredder can be used. The waste paper sheet Pu cut by the coarse crushing section 10 is transferred (transported) to a defibrating apparatus section 23 via a pipe 22 after being received by a hopper 21 provided in the defibrating section 20.
The defibrating apparatus section 23 defibrates the raw material cut by the coarse crushing section 10. Here, a term “defibrate” in the present specification means to disentangle the fibers of the waste paper sheet Pu that serves as a defibration target formed by binding a plurality of fibers, one by one. The defibrating apparatus section 23 also has a function of separating substances, such as resin particles, ink, toner, or bleed inhibitor, that adhere to the raw material, from the fibers.
The material that has passed through the defibrating apparatus section 23 is referred to as “defibrated material”. There is also a case where “defibrated material” includes not only disentangled defibrated material fibers but also resin (resin for binding a plurality of fibers) particles separated from the fibers when disentangling the fibers, a coloring material, such as ink or toner, or additives, such as bleed inhibitor or paper strength enhancer.
The defibrating apparatus section 23 performs the defibration in a so-called dry type in the atmosphere (in the air) without using a solvent, water or the like. Specifically, as the defibrating apparatus section 23, an impeller mill is used. The defibrating apparatus section 23 has a function of generating an airflow that suctions the raw material and discharges the defibrated material. Accordingly, the defibrating apparatus section 23 can suction the raw material together with the airflow from an introduction port 23a by the airflow generated by the defibrating apparatus section 23 itself, perform defibration processing, and transport the defibrated material to a discharge port 23b. The defibrated material that has passed through the defibrating apparatus section 23 is transferred to the sorting section 30 via a pipe 31. In addition, the airflow for transporting the defibrated material from the defibrating apparatus section 23 to the sorting section 30 may use the airflow generated in the defibrating apparatus section 23, or may use the airflow by providing an airflow generating apparatus, such as a blower.
The sorting section 30 introduces the defibrated material defibrated by the defibrating section 20 through the pipe 31 into a sorting apparatus section 33 from the introduction port 32 and sorts the defibrated material according to the length of the fiber. For example, a sieve is used as the sorting apparatus section 33. The sorting apparatus section 33 has a mesh (filter, screen) and can divide the defibrated material into fibers or particles (fibers or particles that have passed through the mesh, that is, a first sorted material) smaller than an aperture of the mesh, and particles, undefibrated pieces, or dams (particles, pieces, or dams that do not pass through the mesh, that is, a second sorted material) larger than the aperture of the mesh. For example, the first sorted material is transferred to the mixing section 50 via a pipe 44. The second sorted material is returned from a discharge port 34 to the defibrating section 20 via a pipe 35. Specifically, the sorting apparatus section 33 is a cylindrical sieve which is rotationally driven by a motor. As the mesh of the sorting apparatus section 33, for example, a wire mesh, an expanded metal obtained by stretching a metal plate with a cut, and a punching metal having a hole formed in a metal plate by a press machine or the like are used.
The first web forming section 40 transports the first sorted material that has passed through the sorting section 30 to the mixing section 50. The first web forming section 40 includes a mesh belt 41, a stretching roller 42, and a suction section (suction mechanism) 43.
The suction section 43 can suction the first sorted material dispersed in the air passing through an opening (mesh opening) of the sorting section 30 onto the mesh belt 41. The first sorted material is suctioned from the sorting section 30 by the suction section 43, is deposited on the moving mesh belt 41, and forms a web V. The basic configuration of the mesh belt 41, the stretching roller 42, and the suction section 43 is the same as that of the mesh belt 71, a stretching roller 72, and a suction section (suction mechanism) 73 of the second web forming section 70 to be described later.
By passing through the sorting section 30 and the first web forming section 40, the web V is formed in a state of containing a large amount of air and being softly bulged. The web V deposited on the mesh belt 41 is inserted into the pipe 44 and transported to the mixing section 50.
The rotating body 45 can cut the web V before the web V is transported to the mixing section 50. In the illustrated example, the rotating body 45 has a base portion 45a and a protrusion portion 45b that protrudes from the base portion 45a. The protrusion portion 45b has, for example, a plate-like shape. In the illustrated example, four protrusion portions 45b are provided, and the four protrusion portions 45b are provided at equivalent intervals. As the base portion 45a rotates in a direction R, the protrusion portion 45b can rotate around the base portion 45a. By cutting the web V with the rotating body 45, for example, it is possible to reduce fluctuation in the amount of the defibrated material per unit time supplied to the depositing section 60 to be described later.
The mixing section 50 passes through the sorting section 30 and mixes the first sorted material transported by the first web forming section 40 and a binder resin powder with each other. The mixing section 50 includes a powder supply device 51 for supplying the binder resin powder, a pipe 52 for transporting the first sorted material and the binder resin powder, and a blower 53. The pipe 52 is continuous with the pipe 44.
In the mixing section 50, the airflow is generated by the blower 53, and the first sorted material and the binder resin powder supplied from the powder supply device 51 can be transported in the pipe 52 while being mixed with each other. The binder resin powder supplied from the powder supply device 51 contains a resin capable of binding a plurality of fibers. At the time when the resin is supplied, the plurality of fibers is not bound. The resin bonds the plurality of fibers by melting when passing through the sheet forming section 80 to be described later. In addition, the mechanism for mixing the first sorted material and the binder resin powder with each other is not particularly limited.
The binder resin powder supplied from the powder supply device 51 is a thermoplastic resin or a thermosetting resin, and examples thereof include 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 an appropriate mixture thereof.
In addition, as the binder resin powder supplied from the powder supply device 51, in addition to the resin for binding the fibers, in accordance with the type of the sheet to be manufactured, a coloring agent for coloring the fibers, a coagulation preventing agent for preventing coagulation of fibers, a flame retardant for making fibers and the like unlikely to burn, and the like, may be included. The mixture of the first sorted material and the binder resin powder that has passed through the mixing section 50 is transferred to the depositing section 60 via the pipe 54.
The depositing section 60 introduces the mixture that has passed through the mixing section 50 from an introduction port 61 into a depositing apparatus section 62, disentangles the intertwined fibers of the defibrated material, and descends while dispersing in the air. Furthermore, in a case where the resin of the binder resin powder supplied from the powder supply device 51 is fibrous, the depositing apparatus section 62 disentangles the intertwined resin fibers. Accordingly, the depositing section 60 can deposit the mixture uniformly on the second web forming section 70.
As the depositing apparatus section 62, a cylindrical sieve having a rotating mesh is used, and allows fibers or particles smaller than the opening of the sieve of the mesh which are contained in the mixture that has passes through the mixing section 50, that is, fibers or particles that can pass through the mesh, pass therethrough. The configuration of the depositing section 60 is, for example, the same as the configuration of the sorting section 30.
In addition, the “sieve” of the depositing apparatus section 62 may not have a function of sorting a specific target. In other words, the “sieve” used as the depositing apparatus section 62 means that the mesh is provided, and may allow all of the mixtures introduced into the depositing apparatus section 62 pass therethrough.
The second web forming section 70 deposits the passing material that has passed through the depositing section 60 and forms a web W. The second web forming section 70 includes, for example, the mesh belt 71, the stretching roller 72, and the suction section (suction mechanism) 73.
While moving, the mesh belt 71 deposits the passing material that has passed through the opening (opening of the mesh) of the depositing section 60. The mesh belt 71 is configured to be stretched by the stretching roller 72, and to make the air pass therethrough while the passing material is unlikely to pass therethrough. The mesh belt 71 continuously moves as the stretching roller 72 rotates. As the passing material that has passed through the depositing section 60 descends and is accumulated on the continuously moving mesh belt 71, the web W is formed on the mesh belt 71.
The suction section 73 is provided below the mesh belt 71 (on a side opposite to the depositing section 60 side). The suction section 73 can generate a downwardly directed airflow (airflow from the depositing section 60 to the mesh belt 71). Accordingly, it is possible to increase a discharge speed of the passing material from the depositing section 60.
As described above, by passing through the depositing section 60 and the second web forming section 70 (web forming step), the web W is formed in a state of containing a large amount of air and being softly bulged. The web W deposited on the mesh belt 71 is transported to the sheet forming section 80. In addition, in the illustrated example, a humidity control section 74 which controls humidity of the web W is provided. In the humidity control section 74, water or water vapor can be added to the web W and the amount ratio between the web W and water can be adjusted.
The sheet forming section 80 pressurizes and heats the web W deposited on the mesh belt 71 and forms a sheet S. In the sheet forming section 80, a plurality of fibers in the mixture can be bound to each other via the binder resin powder by applying heat to the mixture of the defibrated material and the binder resin powder mixed in the web W.
The sheet forming section 80 includes a pressurizing section 81 for pressurizing the web W and a heating section 82 for heating the web W pressurized by the pressurizing section 81. The pressurizing section 81 is configured with a pair of calendar rollers 81a and 81b and applies pressure to the web W. The thickness of the web W is reduced by being pressurized, and the density of the web W is increased. The heating section 82 includes a pair of heating rollers 82a and 82b. The sheet S is formed by heating the web W pressurized by the calendar rollers 81a and 81b with the heating rollers 82a and 82b and binding the fibers by melting the resin. Here, the pressure applied to the web W by the calendar rollers 81a and 81b of the pressurizing section 81 can be set higher than the pressure applied to the web W by the heating rollers 82a and 82b of the heating section 82. In addition, the number of the calendar rollers 81a and 81b or the heating rollers 82a and 82b is not particularly limited.
The cutting section 90 cuts the sheet S formed by the sheet forming section 80. In the illustrated example, the cutting section 90 includes a first cutting section 91 for cutting the sheet S in a direction intersecting the transport direction of the sheet S, and a second cutting section 92 for cutting the sheet S in a direction parallel to the transport direction, for example, a roller cutter. For example, the second cutting section 92 cuts the sheet S that has passed through the first cutting section 91. By passing through the cutting section 90, the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2 of a cut form having a predetermined size cut from the sheet S is formed. The cut printing recycled paper sheet Pr1 of the cut form or the recycled paper sheet Pr2 is discharged to the recycled paper sheet discharge section 100b illustrated in
Regarding the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2 manufactured by the above-described paper sheet recycling section 100, the printing recycled paper sheet Pr1 is supplied by the recycled paper sheet supply section 200 as described in
(Printing Section Operation Confirmation)
When the paper sheet recycling section 100 is started based on the instruction input into the setting section 700, a printing section operation confirming step (S10) for confirming whether or not the printing section 500 is in operation is executed. In a case where the printing section 500 is in an operating state, the printing operation based on a print command received from the outside or instructed from the setting section 700 is not paused in the middle and is continued until the printing is completed. In other words, in a case where the printing section 500 is in operation (YES), the paper sheet recycling section 100 is placed in a standby state for starting the recycling operation of the paper sheet.
(Stop of Receiving Print Instruction from Outside)
In a case where the printing section 500 does not receive the print command or the printing is completed, that is, in the printing section operation confirming step (S10), when it is confirmed that the printing section 500 is not in operation (NO), the print instruction receiving stopping step (S11) is executed such that the printing section 500 does not receive the print command. In other words, so-called offline is achieved. Accordingly, in the setting section 700, an indication, such as “printing section offline” or “printing cannot be input because the recycled paper sheet is currently being manufactured” is displayed on a display section (not illustrated) and guides the operator (person).
(Recycled Paper Sheet Manufacturing)
When the printing section 500 becomes offline (S11), the paper sheet recycling and printing apparatus 1000 shifts to a recycled paper sheet manufacturing step (S12) for manufacturing the recycled paper sheet. In the recycled paper sheet manufacturing step (S12), either one of the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2 is manufactured from the waste paper sheet Pu in the paper sheet recycling section 100 illustrated in
(Determination of Type of Manufactured Recycled Paper Sheet)
A manufactured recycled paper sheet type determining step (S13) is a step for determining whether the recycled paper sheet manufactured in the recycled paper sheet manufacturing (S12) step is the printing recycled paper sheet Pr1 to be supplied for the printing or the recycled paper sheet Pr2 that is not to be supplied for the printing based on the setting information of the setting section 700.
(Supply of Second Recycled Paper Sheet Storage Section)
When it is determined that the recycled paper sheet manufactured by the paper sheet recycling section 100 is the recycled paper sheet Pr2 that is not to be supplied for the printing in the manufactured recycled paper sheet type determining step (S13), the recycled paper sheet Pr2 is supplied to the second recycled paper sheet storage section 330 (S141).
(Confirmation of Supply Amount of Second Recycled Paper Sheet Storage Section)
When the recycled paper sheet Pr2 is supplied to the second recycled paper sheet storage section 330 (S141), a supply amount confirming step (S151) of the second recycled paper sheet storage section 330 for confirming whether or not the manufacturing quantity of the recycled paper sheets Pr2 set by the setting section 700, that is, the quantity of the recycled paper sheets Pr2 supplied to the second recycled paper sheet storage section 330 is the quantity set by the setting section 700, is executed. In addition, in a case where the set quantity has not been reached (NO), the recycled paper sheet manufacturing step (S12) is continued.
(Supply of First Recycled Paper Sheet Storage Section)
Meanwhile, when it is determined that the recycled paper sheet manufactured by the paper sheet recycling section 100 is the printing recycled paper sheet Pr1 to be supplied for the printing in the manufactured recycled paper sheet type determining step (S13), the printing recycled paper sheet Pr1 is supplied to the first recycled paper sheet storage section 320 (S142).
(Confirmation of Supply Amount of First Recycled Paper Sheet Storage Section)
When the printing recycled paper sheet Pr1 is supplied (S142) to the first recycled paper sheet storage section, a supply amount confirming step (S152) of the first recycled paper sheet storage section for confirming whether or not the manufacturing quantity of the printing recycled paper sheets Pr1 set by the setting section 700, that is, the quantity of the printing recycled paper sheets Pr1 supplied to the first recycled paper sheet storage section 320 is the quantity set by the setting section 700, is executed. In addition, in a case where the set quantity has not been reached (NO), the recycled paper sheet manufacturing step (S12) is continued.
(Start of Standby for Receiving Print Instruction from Outside)
In the supply amount confirming step (S151) of the second recycled paper sheet storage section or the supply amount confirming step (S152) of the first recycled paper sheet storage section, when the set quantity of the recycled paper sheets is supplied to the second recycled paper sheet storage section 330 or the first recycled paper sheet storage section 320 (YES), the offline state is canceled, a print instruction receiving standby starting step (S16) from the outside is executed, a message indicating that the printing is possible is displayed in the setting section 700 or the printing section 500. In addition, the manufacturing of the recycled paper sheet in the paper sheet recycling section 100 is stopped.
Next, a flowchart of
(Printing Paper Sheet Selection)
As illustrated in
(First Recycled Paper Sheet Storage Section Storage Amount Confirmation)
When the printing recycled paper sheet Pr1 is selected (YES) in the printing paper sheet selecting step (S20), a first recycled paper sheet storage section storage amount confirming step (S21) for confirming whether or not the printing recycled paper sheet Pr1 is stored in the first recycled paper sheet storage section 320 in which the printing recycled paper sheet Pr1 is stored, is executed. When it is confirmed that at least one printing recycled paper sheet Pr1 is stored (YES), the process shifts to the next printing recycled paper sheet taking-out step (S22).
(Printing Recycled Paper Sheet Taking-Out)
The printing recycled paper sheet taking-out step (S22) is a step for taking out the printing recycled paper sheet Pr1 from the first recycled paper sheet storage section 320 and transporting the printing recycled paper sheet Pr1 to the paper sheet taking-in section 500a of the printing section 500 by the transport section 400. In addition, a printing step (S200) for discharging the printing recycled paper sheet Pr1 transported to the paper sheet taking-in section 500a to the printed material discharge section 500b as the printed material Pp after the predetermined printing is performed by the printing section 500, and storing the printing recycled paper sheet Pr1 in the printed material storage section 600, is executed.
(Printing Quantity Confirmation)
When the printing step (S200) is executed, a printing quantity confirming step (S211) for confirming whether or not the printing quantity based on the printing command has been reached, is executed. When the printing quantity based on the print command has been reached (YES), the printing is completed. In a case where the printing quantity has not been reached (NO), the process shifts to the first recycled paper sheet storage section storage amount confirming step (S21), and printing on the printing recycled paper sheet Pr1 is continued.
(Printing Paper Sheet Reselection)
In a case where it is confirmed that the printing recycled paper sheet Pr1 is not stored (NO) in the step of the above-described first recycled paper sheet storage section storage amount confirming step (S21), a printing paper sheet reselecting step (S23) is executed. In the printing paper sheet reselecting step (S23), selection is performed as to whether to perform the predetermined printing on either the new paper sheet Pn or the printing recycled paper sheet Pr1.
As means for the selection, the operator (person) performs determination from “there is no remaining printing recycled paper sheet Pr1” or “determination of continuation or cancellation of printing” displayed on the display section or the like provided in the paper sheet recycling and printing apparatus 1000, but in this example, it is described that printing is continued. In order to continue the printing, by performing the printing on the new paper sheet Pn in which it is easy to replenish the paper sheets to be supplied for the printing (YES) or without selecting the new paper sheet Pn (NO), the paper sheet recycling section 100 selects whether to continue the printing after manufacturing and storing the printing recycled paper sheet Pr1 in the first recycled paper sheet storage section 320.
When the printing on the new paper sheet Pn (YES) is selected in the printing paper sheet reselecting step (S23), the printing is continued based on the flow in which (NO) to be described later, that is, the new paper sheet Pn, is selected in the printing paper sheet selecting step (S20). Meanwhile, in a case where the new paper sheet Pn is not selected (NO), a shifting step (S24) to the manufacturing flow of the printing recycled paper sheet Pr1 based on the manufacturing flow of the recycled paper sheet illustrated in
At this time, as described in the manufacturing flow of the recycled paper sheet illustrated in
Meanwhile, in a case where the printing recycled paper sheet Pr1 is not selected (NO) in the printing paper sheet selecting step (S20), the new paper sheet Pn stored in the paper sheet storage section 310 is selected. When the new paper sheet Pn is selected, a new paper sheet storage amount confirming step (S30) for confirming the presence or absence of the stored new paper sheet Pn stored in the paper sheet storage section 310, is executed. When it is confirmed that the new paper sheet Pn is stored (YES) in the new paper sheet storage amount confirming step (S30), the taking-out (S31) of the new paper sheet Pn from the paper sheet storage section 310 is executed, and the new paper sheet Pn is supplied to the printing section 500. Then, the printing step (S200) and a printing quantity confirming step (S212) are executed.
In a case where the new paper sheet Pn is not stored in the paper sheet storage section 310 (NO) in the new paper sheet storage amount confirming step (S30), the operator (person) is warned by warning means (not illustrated) and the process shifts to the step (S32) for standing by for replenishing the paper sheet storage section 310 with the new paper sheet Pn. Then, when the paper sheet storage section 310 is replenished with the new paper sheet Pn, the printing is restarted.
In the printing quantity confirming step (S212), in a case where the printing quantity based on the printing command has not been reached (NO), the process shifts to the new paper sheet storage amount confirming step (S30), and then, each step up to the printing step (S200) is executed.
In both of the printing quantity confirming step (S211) in the flow of the printing onto the printing recycled paper sheet Pr1 and the printing quantity confirming step (S212) in the flow of the printing onto the new paper sheet Pn, when the printing quantity based on the printing command has been reached (YES), the printing is completed.
As described above, in the paper sheet recycling and printing apparatus 1000 according to the present embodiment, as illustrated in
The recycled paper sheet Pr2 that is not to be supplied for the printing may be various forms, such as, a recycled paper sheet to be supplied for the printing of another printing machine, or a paper sheet for handwritten memo. Furthermore, the above-described paper sheet recycling section 100 can also perform coloring in the paper sheet recycling section 100 not being limited to a colorless (white) recycled paper sheet, and can also manufacture the color recycled paper sheet, and thus, it is possible to provide the recycled paper sheet not only for the printing but also for various uses other than the printing, such as decoration or origami. Therefore, regarding the recycled paper sheet Pr2 manufactured in the paper sheet recycling section 100, by making it possible to directly take out the stored recycled paper sheet Pr2 from the second recycled paper sheet storage section 330 without passing through the printing section 500, in the printing section 500, it is possible to take out the desired recycled paper sheet Pr2 from the paper sheet recycling and printing apparatus 1000 without interrupting the printing executed in the printing section 500 using the new paper sheet Pn or the printing recycled paper sheet Pr1.

Between the storage section 300 and the printing section 500, the transport section 400 for transporting and supplying the new paper sheet Pn or the printing recycled paper sheet Pr1 that is stored in the storage section 300 and serve as the recording target medium to the printing section 500, is provided.
The transport section 400 includes: paper sheet acquiring means 410 for picking up the desired paper sheet from the paper sheet storage section 310 in which the new paper sheet Pn is stored or the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 in which the printing recycled paper sheet Pr1 is stored; and the paper sheet transport means 420 (not illustrated in detail) for transporting the paper sheet picked up by the paper sheet acquiring means 410 to the paper sheet supply section 400a.
The paper sheet acquiring means 410 is driven by the driving means that serves as the transport switching means (not illustrated) at the position at which the paper sheet storage section 310 in which the new paper sheet Pn is stored or the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 in which the printing recycled paper sheet Pr1 is stored are disposed by a paper sheet selection command from the printing section 500, and can pick up a desired paper sheet.
The printing recycled paper sheet Pr1 or the new paper sheet Pn supplied from the paper sheet supply section 400a of the transport section 400 is taken into the apparatus from the paper sheet taking-in section 500a of the printing section 500, and is discharged to the printed material discharge section 500b that serves as the recording target medium discharge section as the printed material Pp on which the desired recording information is printed. In addition, the printing section 500 is not particularly limited as long as the printing section 500 forms the printed material Pp by making toner or ink of the recording medium adhere to the surface of the recording target medium, such as a so-called laser printer or an ink jet printer.
The waste paper sheet supply section 100a supplies the waste paper sheet Pu to the coarse crushing section 10. The waste paper sheet supply section 100a is, for example, an automatic inserting section for continuously inserting the waste paper sheet Pu to the coarse crushing section 10. The waste paper sheet Pu supplied by the waste paper sheet supply section 100a is not limited to the waste paper sheet but may be any paper sheet containing fibers, for example, a pulp sheet.
In the coarse crushing section 10, the waste paper sheet Pu supplied by the waste paper sheet supply section 100a is cut into pieces by cutting in the air. The shape or size of the pieces is, for example, several cm square. In the example illustrated in the drawing, the coarse crushing section 10 has the coarse crushing blade 11, and the coarse crushing blade 11 can cut the inserted raw material. As the coarse crushing section 10, for example, a shredder can be used. The waste paper sheet Pu cut by the coarse crushing section 10 is transferred (transported) to the defibrating apparatus section 23 via the pipe 22 after being received by the hopper 21 provided in the defibrating section 20.
The defibrating apparatus section 23 defibrates the raw material cut by the coarse crushing section 10. Here, a term “defibrate” in the present specification means to disentangle the fibers of the waste paper sheet Pu that serves as a defibration target formed by binding a plurality of fibers, one by one. The defibrating apparatus section 23 also has a function of separating substances, such as resin particles, ink, toner, or bleed inhibitor, that adhere to the raw material, from the fibers.
The material that has passed through the defibrating apparatus section 23 is referred to as “defibrated material”. There is also a case where “defibrated material” includes not only disentangled defibrated material fibers but also resin (resin for binding a plurality of fibers) particles separated from the fibers when disentangling the fibers, a coloring material, such as ink or toner, or additives, such as bleed inhibitor or paper strength enhancer.
The defibrating apparatus section 23 performs the defibration in a so-called dry type in the atmosphere (in the air) without using a solvent, water or the like. Specifically, as the defibrating apparatus section 23, an impeller mill is used. The defibrating apparatus section 23 has a function of generating an airflow that suctions the raw material and discharges the defibrated material. Accordingly, the defibrating apparatus section 23 can suction the raw material together with the airflow from the introduction port 23a by the airflow generated by the defibrating apparatus section 23 itself, perform defibration processing, and transport the defibrated material to the discharge port 23b. The defibrated material that has passed through the defibrating apparatus section 23 is transferred to the sorting section 30 via the pipe 31. In addition, the airflow for transporting the defibrated material from the defibrating apparatus section 23 to the sorting section 30 may use the airflow generated in the defibrating apparatus section 23, or may use the airflow by providing an airflow generating apparatus, such as a blower.
The sorting section 30 introduces the defibrated material defibrated by the defibrating section 20 through the pipe 31 into the sorting apparatus section 33 from the introduction port 32 and sorts the defibrated material according to the length of the fiber. For example, a sieve is used as the sorting apparatus section 33. The sorting apparatus section 33 has a mesh (filter, screen) and can divide the defibrated material into fibers or particles (fibers or particles that have passed through the mesh, that is, a first sorted material) smaller than an aperture of the mesh, and particles, undefibrated pieces, or dams (particles, pieces, or dams that do not pass through the mesh, that is, a second sorted material) larger than the aperture of the mesh. For example, the first sorted material is transferred to the mixing section 50 via the pipe 44. The second sorted material is returned from the discharge port 34 to the defibrating section 20 via the pipe 35. Specifically, the sorting apparatus section 33 is a cylindrical sieve which is rotationally driven by a motor. As the mesh of the sorting apparatus section 33, for example, a wire mesh, an expanded metal obtained by stretching a metal plate with a cut, and a punching metal having a hole formed in a metal plate by a press machine or the like are used.
The first web forming section 40 transports the first sorted material that has passed through the sorting section 30 to the mixing section 50. The first web forming section 40 includes the mesh belt 41, the stretching roller 42, and the suction section (suction mechanism) 43.
The suction section 43 can suction the first sorted material dispersed in the air passing through an opening (mesh opening) of the sorting section 30 onto the mesh belt 41. The first sorted material is suctioned from the sorting section 30 by the suction section 43, is deposited on the moving mesh belt 41, and forms the web V. The basic configuration of the mesh belt 41, the stretching roller 42, and the suction section 43 is the same as that of the mesh belt 71, the stretching roller 72, and the suction section (suction mechanism) 73 of the second web forming section 70 to be described later.
By passing through the sorting section 30 and the first web forming section 40, the web V is formed in a state of containing a large amount of air and being softly bulged. The web V deposited on the mesh belt 41 is inserted into the pipe 44 and transported to the mixing section 50.
The rotating body 45 can cut the web V before the web V is transported to the mixing section 50. In the illustrated example, the rotating body 45 has the base portion 45a and the protrusion portion 45b that protrudes from the base portion 45a. The protrusion portion 45b has, for example, a plate-like shape. In the illustrated example, four protrusion portions 45b are provided, and the four protrusion portions 45b are provided at equivalent intervals. As the base portion 45a rotates in the direction R, the protrusion portion 45b can rotate around the base portion 45a. By cutting the web V with the rotating body 45, for example, it is possible to reduce fluctuation in the amount of the defibrated material per unit time supplied to the depositing section 60 to be described later.
The mixing section 50 passes through the sorting section 30 and mixes the first sorted material transported by the first web forming section 40 and a binder resin powder with each other. The mixing section 50 includes the powder supply device 51 for supplying the binder resin powder, the pipe 52 for transporting the first sorted material and the binder resin powder, and the blower 53. The pipe 52 is continuous with the pipe 44.
In the mixing section 50, the airflow is generated by the blower 53, and the first sorted material and the binder resin powder supplied from the powder supply device 51 can be transported in the pipe 52 while being mixed with each other. The binder resin powder supplied from the powder supply device 51 contains a resin capable of binding a plurality of fibers. At the time when the resin is supplied, the plurality of fibers is not bound. The resin bonds the plurality of fibers by melting when passing through the sheet forming section 80 to be described later. In addition, the mechanism for mixing the first sorted material and the binder resin powder with each other is not particularly limited.
The binder resin powder supplied from the powder supply device 51 is a thermoplastic resin or a thermosetting resin, and examples thereof include 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 an appropriate mixture thereof.
In addition, as the binder resin powder supplied from the powder supply device 51, in addition to the resin for binding the fibers, in accordance with the type of the sheet to be manufactured, a coloring agent for coloring the fibers, a coagulation preventing agent for preventing coagulation of fibers, a flame retardant for making fibers and the like unlikely to burn, and the like, may be included. The mixture of the first sorted material and the binder resin powder that has passed through the mixing section 50 is transferred to the depositing section 60 via the pipe 54.
The depositing section 60 introduces the mixture that has passed through the mixing section 50 from the introduction port 61 into the depositing apparatus section 62, disentangles the intertwined fibers of the defibrated material, and descends while dispersing in the air. Furthermore, in a case where the resin of the binder resin powder supplied from the powder supply device 51 is fibrous, the depositing apparatus section 62 disentangles the intertwined resin fibers. Accordingly, the depositing section 60 can deposit the mixture uniformly on the second web forming section 70.
As the depositing apparatus section 62, a cylindrical sieve having a rotating mesh is used, and allows fibers or particles smaller than the opening of the sieve of the mesh which are contained in the mixture that has passes through the mixing section 50, that is, fibers or particles that can pass through the mesh, pass therethrough. The configuration of the depositing section 60 is, for example, the same as the configuration of the sorting section 30.
In addition, the “sieve” of the depositing apparatus section 62 may not have a function of sorting a specific target. In other words, the “sieve” used as the depositing apparatus section 62 means that the mesh is provided, and may allow all of the mixtures introduced into the depositing apparatus section 62 pass therethrough.
The second web forming section 70 deposits the passing material that has passed through the depositing section 60 and forms the web W. The second web forming section 70 includes, for example, the mesh belt 71, the stretching roller 72, and the suction section (suction mechanism) 73.
While moving, the mesh belt 71 deposits the passing material that has passed through the opening (opening of the mesh) of the depositing section 60. The mesh belt 71 is configured to be stretched by the stretching roller 72, and to make the air pass therethrough while the passing material is unlikely to pass therethrough. The mesh belt 71 continuously moves as the stretching roller 72 rotates. As the passing material that has passed through the depositing section 60 descends and is accumulated on the continuously moving mesh belt 71, the web W is formed on the mesh belt 71.
The suction section 73 is provided below the mesh belt 71 (on a side opposite to the depositing section 60 side). The suction section 73 can generate a downwardly directed airflow (airflow from the depositing section 60 to the mesh belt 71). Accordingly, it is possible to increase a discharge speed of the passing material from the depositing section 60.
As described above, by passing through the depositing section 60 and the second web forming section 70 (web forming step), the web W is formed in a state of containing a large amount of air and being softly bulged. The web W deposited on the mesh belt 71 is transported to the sheet forming section 80. In addition, in the illustrated example, the humidity control section 74 which controls humidity of the web W is provided. In the humidity control section 74, water or water vapor can be added to the web W and the amount ratio between the web W and water can be adjusted.
The sheet forming section 80 pressurizes and heats the web w deposited on the mesh belt 71 and forms the sheet S. In the sheet forming section 80, a plurality of fibers in the mixture can be bound to each other via the binder resin powder by applying heat to the mixture of the defibrated material and the binder resin powder mixed in the web W.
The sheet forming section 80 includes the pressurizing section 81 for pressurizing the web W and the heating section 82 for heating the web W pressurized by the pressurizing section 81. The pressurizing section 81 is configured with the pair of calendar rollers 81a and 81b and applies pressure to the web W. The thickness of the web W is reduced by being pressurized, and the density of the web W is increased. The heating section 82 includes the pair of heating rollers 82a and 82b. The sheet S is formed by heating the web W pressurized by the calendar rollers 81a and 81b with the heating rollers 82a and 82b and binding the fibers by melting the resin. Here, the pressure applied to the web W by the calendar rollers 81a and 81b of the pressurizing section 81 can be set higher than the pressure applied to the web W by the heating rollers 82a and 82b of the heating section 82. In addition, the number of the calendar rollers 81a and 81b or the heating rollers 82a and 82b is not particularly limited.
The cutting section 90 cuts the sheet S formed by the sheet forming section 80. In the illustrated example, the cutting section 90 includes the first cutting section 91 for cutting the sheet S in a direction intersecting the transport direction of the sheet S, and the second cutting section 92 for cutting the sheet S in a direction parallel to the transport direction, for example, a roller cutter. For example, the second cutting section 92 cuts the sheet S that has passed through the first cutting section 91. By passing through the cutting section 90, the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2 of a cut form having a predetermined size cut from the sheet S is formed. The cut printing recycled paper sheet Pr1 of the cut form or the recycled paper sheet Pr2 is discharged to the recycled paper sheet discharge section (second recycled paper sheet storage section) 100b illustrated in
Regarding the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2 formed by the above-described paper sheet recycling section 100, the printing recycled paper sheet Pr1 is supplied to and stored in any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 by the recycled paper sheet supply section 200 as described in
In this manner, from the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324, one recycled paper sheet storage section (first recycled paper sheet storage section) to which the printing recycled paper sheet Pr1 is supplied by the recycled paper sheet supply section 200, and one recycled paper sheet storage section (first recycled paper sheet storage section) from which the recycled paper sheet Pr is taken out by the transport section 400, are selected.
In addition, in the following description, one recycled paper sheet storage section (first recycled paper sheet storage section) selected from the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 from which the printing recycled paper sheet Pr1 is taken out by the transport section 400, is set as a predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A. Meanwhile, one recycled paper sheet storage section (first recycled paper sheet storage section) selected from the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 to which the printing recycled paper sheet Pr1 is supplied by the recycled paper sheet supply section 200, is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B.
(Manufactured Recycled Paper Sheet Selection)
When the operation of the paper sheet recycling section 100 is started, firstly, the manufactured recycled paper sheet selection (S1) is executed. The manufactured recycled paper sheet selection (S1) is a step for selecting whether the recycled paper sheet formed by the paper sheet recycling section 100 is the printing recycled paper sheet Pr1 to be supplied for the printing or the recycled paper sheet Pr2 that is not to be supplied for the printing. When the manufacturing of the printing recycled paper sheet Pr1 is selected in the manufactured recycled paper sheet selection (S1), the process shifts to setting (S10) of the recycled paper sheet storage section (first recycled paper sheet storage section) which is the next step.
(Setting of Predetermined First Recycled Paper Sheet Storage Section)
When the manufacturing of the printing recycled paper sheet Pr1 is selected in the manufactured recycled paper sheet selection (S1), the setting (S10) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) is executed. As described above, the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A indicates one recycled paper sheet storage section (first recycled paper sheet storage section) which is selected from the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 and from which the printing recycled paper sheet Pr1 is taken out by the transport section 400. In other words, among the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324, one recycled paper sheet storage section (first recycled paper sheet storage section) in which the printing recycled paper sheet Pr1 can be transported to the printing section 500 is set as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A. In addition, when the operation of the paper sheet recycling section 100 is started, when the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A has already been set, it is not necessary to reset the paper sheet storage section.
In the paper sheet recycling and printing apparatus 1000 according to the present embodiment illustrated in
(Setting of Another First Recycled Paper Sheet Storage Section)
Next, the setting (S11) of another recycled paper sheet storage section (another first recycled paper sheet storage section) in which, among the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 323, and 324 except for the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A (322), one recycled paper sheet storage section (first recycled paper sheet storage section) in which the printing recycled paper sheet Pr1 supplied from the recycled paper sheet recycling section 100 and transported by the recycled paper sheet supply section 200 is stored is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, is executed.
Among the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 323, and 324 except for the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A (322), the recycled paper sheet storage section (first recycled paper sheet storage section) in which the printing recycled paper sheet Pr1 is not stored is selected as another recycled paper sheet storage section (another recycled paper sheet storage section) 32B. In the present embodiment, the recycled paper sheet storage section (first recycled paper sheet storage section) 321 is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B and the printing recycled paper sheet Pr1 is supplied.
In addition, when setting another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, it is not necessary to select the recycled paper sheet storage section (first recycled paper sheet storage section) in which there is no printing recycled paper sheet Pr1. For example, in a case where the recycled paper sheet storage section (first recycled paper sheet storage section) which has already reached the maximum storage amount of the printing recycled paper sheets Pr1 has been excluded from options, and further, there is no recycled paper sheet storage section (first recycled paper sheet storage section) which is empty without the printing recycled paper sheet Pr1, even when the printing recycled paper sheet Pr1 is stored, it is possible to select another recycled paper sheet storage section among the recycled paper sheet storage sections (first recycled paper sheet storage sections) having a region in which the new printing recycled paper sheet Pr1 can be stored. In the paper sheet recycling and printing apparatus 1000 illustrated in the present embodiment, in order to supply the printing recycled paper sheet Pr1 to the recycled paper sheet storage section (first recycled paper sheet storage section) 321 as illustrated in
(Recycled Paper Sheet Supply)
When another recycled paper sheet storage section (another first recycled paper sheet storage section) is set (S11), the supply (S12) of the printing recycled paper sheet from the first recycled paper sheet supply means (recycled paper sheet storage and supply means) 221 of the recycled paper sheet supply section 200 to the set another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, is executed.
(Printing Recycled Paper Sheet Storage Amount Detection)
When the printing recycled paper sheet Pr1 is supplied to another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, the recycled paper sheet storage among detection (S13) in another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B is performed. In the printing recycled paper sheet storage amount detection (S13), in a case where the maximum storage amount is not satisfied, that is, NO, the printing recycled paper sheet supply (S12) is performed again. However, in a case where the maximum storage amount has been reached, that is, YES, the process shifts to the next resetting (S14) of another recycled paper sheet storage section (another first recycled paper sheet storage section).
(Resetting of Another First Recycled Paper Sheet Storage Section)
When the recycled paper sheet storage section (first recycled paper sheet storage section) 321 illustrated in
In a case where both or any one of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 323 and 324 have the region in which the printing recycled paper sheet Pr1 can be stored (YES), the process shifts to the setting (S11) of another recycled paper sheet storage section (another first recycled paper sheet storage section), and the printing recycled paper sheet Pr1 is stored in the newly set another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B. However, in a case where there is no region in which the printing recycled paper sheet Pr1 can be stored, that is, in a case where the maximum storage amount has been reached (NO), in any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 323 and 324, it is confirmed (S15) whether or not the paper sheet recycling and printing apparatus 1000 receives a manufacturing instruction of the recycled paper sheet Pr2 that is not to be supplied for the printing, and when the manufacturing instruction of the recycled paper sheet Pr2 is not received (NO), the paper sheet recycling section 100 is stopped, and the supply of the printing recycled paper sheet Pr1 is paused. Meanwhile, in a case where the paper sheet recycling and printing apparatus 1000 receives the manufacturing instruction of the recycled paper sheet Pr2 (YES), the process shifts to the supply (S20) of the recycled paper sheet Pr2 that is to be described later and not to be supplied for the printing to the recycled paper sheet discharge.
In addition, in a case where the process shifts to the step of confirmation (S15) of the manufacturing instruction of the recycled paper sheet Pr2 before stopping the paper sheet recycling section 100, not only the paper sheet recycling section 100 is stopped by the above-described flow, but also the paper sheet recycling section 100 is stopped in the following case. For example, in a case where the planned forming quantity of the printing recycled paper sheet Pr1 with respect to the paper sheet recycling section 100 is input into the control section in advance and the planned forming quantity has been reached, the process shifts to the step (815) of the manufacturing instruction of the recycled paper sheet Pr2 before stopping the paper sheet recycling section 100, and shifts to the stop of the paper sheet recycling section 100. Otherwise, in a case where all of the waste paper sheets Pu that serve as the raw material supplied to the waste paper sheet supply section 100a is consumed, the process shifts to the step of confirming (S15) the manufacturing instruction of the recycled paper sheet Pr2 before stopping the paper sheet recycling section 100, and the paper sheet recycling section 100 is stopped or paused while the waste paper sheet Pu is supplied again.
As described above, since any of the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 provided in the recycled paper sheet storage unit 320 is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B to which the printing recycled paper sheet Pr1 is supplied, even when the paper sheet recycling section 100 is continuously operated, the printing recycled paper sheet Pr1 formed by the paper sheet recycling section 100 is supplied to any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324, and can be stored therein.
In other words, in the paper sheet recycling section 100 provided in the paper sheet recycling and printing apparatus 1000 according to the present embodiment described with reference to
In addition, from the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324, from the recycled paper sheet storage section (first recycled paper sheet storage section) except for the recycled paper sheet storage section (first recycled paper sheet storage section) (first recycled paper sheet storage section 322 of
In the manufactured recycled paper sheet selection (S1) illustrated in
(Recycled Paper Sheet Pr2 Quantity Confirmation)
By the supply of the recycled paper sheet Pr2 to the recycled paper sheet discharge section (second recycled paper sheet storage section) 600 (S20), the recycled paper sheet Pr2 is supplied to and stored in the recycled paper sheet discharge section (second recycled paper sheet storage section) 600. Then, the recycled paper sheet Pr2 quantity confirmation (S21) for confirming whether or not the manufacturing quantity of the recycled paper sheets Pr2 instructed to the paper sheet recycling and printing apparatus 1000 has already been reached, is executed.
In the recycled paper sheet Pr2 quantity confirmation (S21), in a case where the designated quantity has not been reached (NO), the supply (S20) of the recycled paper sheet Pr2 to recycled paper sheet discharge section (second recycled paper sheet storage section) 600, is executed. However, in the recycled paper sheet Pr2 quantity confirmation (S21), in a case where the designated quantity has been reached (YES), it is confirmed whether or not the paper sheet recycling and printing apparatus 1000 has received the manufacturing instruction of the printing recycled paper sheet Pr1 to be supplied for the printing (S22), and when the manufacturing instruction of the printing recycled paper sheet Pr1 is not received (NO), the paper sheet recycling section 100 is stopped and the supply of the recycled paper sheet Pr2 is paused. Meanwhile, in a case where the paper sheet recycling and printing apparatus 1000 receives the manufacturing instruction of the printing recycled paper sheet Pr1 (YES), the process shifts to the setting (S10) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) in the supply flow of the printing recycled paper sheet Pr1, and the supply flow of the above-described printing recycled paper sheet Pr1 is executed.
The recycled paper sheet formed in the paper sheet recycling section 100 provided in the paper sheet recycling and printing apparatus 1000 according to the present embodiment includes the printing recycled paper sheet Pr1 to be supplied for the printing and the recycled paper sheet Pr2 that is not to be supplied for the printing according to the use. In addition, the printing recycled paper sheet Pr1 is supplied to any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 provided in the recycled paper sheet storage section 320 by the recycled paper sheet supply section 200 and is stored therein, and the recycled paper sheet Pr2 is supplied to and stored in the recycled paper sheet discharge section (second recycled paper sheet storage section) 600.
Next, a flowchart of
(Printing Paper Sheet Selection)
As illustrated in
(Selection Information Acquisition of First Recycled Paper Sheet Storage Section)
When the printing recycled paper sheet Pr1 is selected (YES) in the printing paper sheet selection (S30), the selection information acquisition (S31) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A is executed, and the information on which one of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 is set as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A is acquired.
The predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A described with reference to
(Recycled Paper Sheet Storage Amount Confirmation)
From the information acquired in the selection information acquisition (S31) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section), that is, the information indicating that the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A is the recycled paper sheet storage section (first recycled paper sheet storage section) 322, the recycled paper sheet storage amount confirmation (S32) for confirming the presence or absence of the printing recycled paper sheet Pr1 of the recycled paper sheet storage section (first recycled paper sheet storage section) 322 is performed. When it is confirmed that at least one printing recycled paper sheet Pr1 is stored (YES), the process shifts to the next recycled paper sheet taking-out.
(Recycled Paper Sheet Taking-Out)
The printing recycled paper sheet taking-out (S33) in which the printing recycled paper sheet Pr1 is taken out from the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A and is transported to the paper sheet taking-in section 500a of the printing section 500 by the transport section 400, is executed. In addition, the predetermined printing is executed (S200) by the printing section 500 with respect to the printing recycled paper sheet Pr1 transported to the paper sheet taking-in section 500a, and the printing recycled paper sheet Pr1 is discharged to the printed material discharge section 500b as the printed material Pp.
(Printing Quantity Confirmation)
When the printing is executed (S200), printing quantity confirmation (S210) for confirming whether or not the printing quantity commanded by the print command has been reached, is performed. Then, when it is confirmed that the predetermined quantity of the printed materials Pp is obtained, the printing is completed.
In the above-described recycled paper sheet storage amount confirmation (S32), in a case where it is confirmed that the printing recycled paper sheet Pr1 is not stored (NO) in the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A in which the printing recycled paper sheet Pr1 is confirmed in the selection information acquisition (S31) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) in the previous step, the resetting (S34) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A is performed.
(Resetting of Predetermined First Recycled Paper Sheet Storage Section)
When it is confirmed that the printing recycled paper sheet Pr1 is not stored in the recycled paper sheet storage section (first recycled paper sheet storage section) 322 set in the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A, the resetting (S34) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) is executed, and except for the recycled paper sheet storage section (first recycled paper sheet storage section) 321 set in the above-described another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 323 and 324 provided in the recycled paper sheet storage unit 320 is set as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A again.
In addition, as described with reference to the above-described
Regarding which of the recycled paper sheet storage sections (first recycled paper sheet storage section) 323 and 324 is to be set as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A, the invention is not particularly limited as long as the printing recycled paper sheet Pr1 is stored. For example, the recycled paper sheet storage section (first recycled paper sheet storage section) with a large storage amount of the printing recycled paper sheets Pr1 may be selected, or may be selected and instructed by the operator (person). In addition, although not illustrated, in a case where the printing recycled paper sheet Pr1 is not stored in all of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324, the operator (person) is warned by the warning means (not illustrated), and the printing is completed.
When the new predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A is set by the resetting (S34) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section), the process shifts to the selection information acquisition (S31) of the first recycled paper sheet storage section (first recycled paper sheet storage section), and the steps after the recycled paper sheet storage amount confirmation (S32) are executed.
Meanwhile, in a case where the printing recycled paper sheet Pr1 is not selected (NO) in the printing paper sheet selection (S30), the paper sheet storage section 310 in which the new paper sheet Pn is stored is selected. When the paper sheet storage section 310 is selected, the new paper sheet storage amount confirmation (S40) for confirming the presence or absence of the stored new paper sheet Pn stored in the paper sheet storage section 310, is performed. When it is confirmed that the new paper sheet Pn is stored (YES) in the new paper sheet storage amount confirmation (S40), the taking-out (S41) of the new paper sheet Pn from the paper sheet storage section 310 is performed, and the new paper sheet Pn is supplied to the printing section 500. Then, the printing (S200) and the printing quantity confirmation (S210) are executed.
Meanwhile, in a case where the new paper sheet Pn is not stored in the paper sheet storage section 310 (NO), the operator (person) is warned by warning means (not illustrated) and the paper sheet storage section 310 is replenished with the new paper sheet Pn (S42). In addition, when the paper sheet recycling and printing apparatus 1000 receives the command, such as a print restart command, the printing is restarted.
In addition, in the printing quantity confirmation (S210), in a case where the printing quantity based on the printing command has not been reached (NO), the process shifts to the recycled paper sheet storage amount confirming (S32) step in the flow of selecting the printing recycled paper sheet Pr1 as the printing paper sheet, and then the steps up to the next printing (S200) are executed. Similarly, in the flow in which the new paper sheet Pn is selected as the printed paper sheet, the process shifts to the new paper sheet storage amount confirming (S40) step, and then the steps up to the printing (S200) are executed.
Above, in the paper sheet recycling and printing apparatus 1000 according to the described present embodiment, as the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 are provided in the recycled paper sheet storage unit 320 as illustrated in
Furthermore, when one of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 323, and 324 except for the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A, that is, the recycled paper sheet storage section (first recycled paper sheet storage section) 322 in the example of the setting of the present embodiment, is reset (step S34) as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A again, any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 323 and 324 further except for another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B to which the printing recycled paper sheet Pr1 formed in the paper sheet recycling section 100 is supplied and the recycled paper sheet storage section (first recycled paper sheet storage section) 321 in the example of the setting of the present embodiment, is reset as another recycled paper sheet storage section (first recycled paper sheet storage section) 32B. Therefore, when the printing recycled paper sheet Pr1 transported from the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A to the printing section 500 is taken out, there is no case where the supply of the printing recycled paper sheet Pr1 from the paper sheet recycling section 100 overlaps the taking-out. Therefore, it is possible to prevent occurrence of jamming at the time of paper feeding to the printing section 500.
As illustrated in
In addition, in the paper sheet recycling and printing apparatus 1100 illustrated in
The recycled paper sheet supply section 700 transports any of the printing recycled paper sheet Pr1 formed by the paper sheet recycling section 100 and the recycled paper sheet Pr2 that is not to be supplied for the printing to the storage section 800. Then, the transport section 900 can transport any of the new paper sheet Pn, the printing recycled paper sheet Pr1, or the recycled paper sheet Pr2 stored in the storage section 800 to the printing section 500.
The recycled paper sheet supply section 700 for transporting the printing recycled paper sheet Pr1 or the recycled paper sheet Pr2 formed in the paper sheet recycling section 100 to the storage section 800 includes the recycled paper sheet transport means 710 and the recycled paper sheet supply means 720 (not illustrated in detail). The waste paper sheet Pu is inserted into the paper sheet recycling section 100 from the waste paper sheet supply section 100a provided in the paper sheet recycling section 100, and the recycled printing recycled paper sheet Pr1 or recycled paper sheet Pr2 are delivered to the recycled paper sheet insertion port 710a provided in the recycled paper sheet supply section 700 from the recycled paper sheet discharge section (second recycled paper sheet storage section) 100b.
In a case where the printing recycled paper sheet Pr1 is inserted into the recycled paper sheet insertion port 710a, the recycled paper sheet transport means 710 is switched to transport the printing recycled paper sheet Pr1 to the recycled paper sheet supply means 720 by the driving section that serves as the supply section switching means (not illustrated). The recycled paper sheet supply means 720 moves such that the printing recycled paper sheet Pr1 can be supplied to any of the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 provided in the printing recycled paper sheet storage unit 820 provided in the storage section 800 by the driving means that serves as the storage section switching means (not illustrated), and stores the printing recycled paper sheet Pr1 therein. In the present embodiment, an aspect in which the printing recycled paper sheet Pr1 is stored in the printing recycled paper sheet storage section (first recycled paper sheet storage section) 821 is exemplified.
Between the storage section 800 and the printing section 500, the transport section 900 for transporting and supplying the new paper sheet Pn or the printing recycled paper sheet Pr1 that is stored in the storage section 800 and serves as the recording target medium or the recycled paper sheet Pr2 to the printing section 500, is provided.
The transport section 900 includes: paper sheet acquiring means 910 for picking up the desired paper sheet from the paper sheet storage section 810 in which the new paper sheet Pn is stored, the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 in which the printing recycled paper sheet Pr1 is stored, or the recycled paper sheet storage section 830 (second recycled paper sheet storage section) in which the recycled paper sheet Pr2 is stored; and the paper sheet transport means 920 (not illustrated in detail) for transporting the paper sheet picked up by the paper sheet acquiring means 910 to the paper sheet supply section 900a.
The paper sheet acquiring means 910 is driven by the driving means that serves as the transport switching means (not illustrated) at the position at which the paper sheet storage section 810 in which the new paper sheet Pn is stored, the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 in which the printing recycled paper sheet Pr1 is stored, or the recycled paper sheet storage section 830 (second recycled paper sheet storage section) in which the recycled paper sheet Pr2 is stored are disposed, by the paper sheet selection command from the printing section 500, and can pick up a desired paper sheet.
The printing recycled paper sheet Pr1 supplied from the paper sheet supply section 900a of the transport section 900 or the new paper sheet Pn is taken into the apparatus from the paper sheet taking-in section 500a of the printing section 500, and is discharged to the printed material discharge section 500b as the printed material Pp on which the desired recording information is printed. In addition, in a case where the recycled paper sheet Pr2 is taken into the printing section 500, the instruction of no printing information is sent from the apparatus control section and is discharged to the printed material discharge section 500b in a state without printing, that is, in a state of the recycled paper sheet Pr2. In other words, in the paper sheet recycling and printing apparatus 1100 according to the present embodiment, as the recycled paper sheet discharge section (second recycled paper sheet storage section) 600 provided in the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment, the printed material discharge section 500b of the printing section 500 is disposed. In addition, the printing section 500 is not particularly limited as long as the printing section 500 is an apparatus that forms the printed material Pp by making toner or ink of the recording medium adhere to the surface of the recording target medium, such as a so-called laser printer or an ink jet printer.
In addition, in the following description, one printing recycled paper sheet storage section (first recycled paper sheet storage section) selected from the plurality of printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 from which the printing recycled paper sheet Pr1 is taken out by the transport section 900, is set as the predetermined printing recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A. Meanwhile, one printing recycled paper sheet storage section (first recycled paper sheet storage section) selected from the plurality of printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 from which the printing recycled paper sheet Pr1 is supplied by the recycled paper sheet supply section 700, is set as another printing recycled paper sheet storage section (another first recycled paper sheet storage section) 32B.
(Manufactured Recycled Paper Sheet Selection)
When the operation of the paper sheet recycling section 100 is started, firstly, the manufactured recycled paper sheet selection (S1) is executed. The manufactured recycled paper sheet selection (S1) is a step for selecting whether the recycled paper sheet formed by the paper sheet recycling section 100 is the printing recycled paper sheet Pr1 to be supplied for the printing or the recycled paper sheet Pr2 that is not to be supplied for the printing. When the manufacturing of the printing recycled paper sheet Pr1 is selected in the manufactured recycled paper sheet selection (S1), the process shifts to setting (S50) of the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) which is the next step.
(Setting of Predetermined First Recycled Paper Sheet Storage Section)
When the manufacturing of the printing recycled paper sheet Pr1 is selected in the manufactured recycled paper sheet selection (S1), the setting (S50) of the predetermined first recycled paper sheet storage section is executed. As described above, the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A indicates one printing recycled paper sheet storage section (first recycled paper sheet storage section) which is selected from the plurality of printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 and from which the printing recycled paper sheet Pr1 is taken out by the transport section 900. In other words, among the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824, one printing recycled paper sheet storage section (first recycled paper sheet storage section) in which the printing recycled paper sheet Pr1 can be transported to the printing section 500 is set as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A. In addition, when the operation of the paper sheet recycling section 100 is started, when the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A has already been set, it is not necessary to reset the paper sheet storage section.
In the paper sheet recycling and printing apparatus 1100 according to the present embodiment illustrated in
(Setting of Another First Recycled Paper Sheet Storage Section)
Next, the setting (S51) of another first recycled paper sheet storage section in which, among the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 823, and 824 except for the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A (822), one printing recycled paper sheet storage section (first recycled paper sheet storage section) in which the printing recycled paper sheet Pr1 supplied from the recycled paper sheet recycling section 100 and transported by the recycled paper sheet supply section 700 is stored is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, is executed.
Among the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 823, and 824 except for the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A (822), the printing recycled paper sheet storage section (first recycled paper sheet storage section) in which the printing recycled paper sheet Pr1 is not stored is selected as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B. In the present embodiment, the printing recycled paper sheet storage section (first recycled paper sheet storage section) 821 is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B and the printing recycled paper sheet Pr1 is supplied.
In addition, when setting another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, it is not necessary to select the printing recycled paper sheet storage section (first recycled paper sheet storage section) in which there is no printing recycled paper sheet Pr1. For example, in a case where the printing recycled paper sheet storage section (first recycled paper sheet storage section) which has already reached the maximum storage amount of the printing recycled paper sheets Pr1 has been excluded from options, and further, there is no printing recycled paper sheet storage section (first recycled paper sheet storage section) which is empty without the printing recycled paper sheet Pr1, even when the printing recycled paper sheet Pr1 is stored, it is possible to select another recycled paper sheet storage section among the recycled paper sheet storage sections (first recycled paper sheet storage sections) having a region in which the new printing recycled paper sheet Pr1 can be stored. In the paper sheet recycling and printing apparatus 1100 illustrated in the present embodiment, in order to supply the printing recycled paper sheet Pr1 to the printing recycled paper sheet storage section (first recycled paper sheet storage section) 821 as illustrated in
(Recycled Paper Sheet Supply)
When another recycled paper sheet storage section (another first recycled paper sheet storage section) is set (S51), the supply (S52) of the printing recycled paper sheet from the recycled paper sheet supply means 720 of the recycled paper sheet supply section 700 to the set another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, is executed.
(Printing Recycled Paper Sheet Storage Amount Detection)
When the printing recycled paper sheet Pr1 is supplied to another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B, the printing recycled paper sheet storage among detection (S53) in another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B is performed. In the printing recycled paper sheet storage amount detection (S53), in a case where the maximum storage amount is not satisfied, that is, NO, the printing recycled paper sheet supply (S52) is performed again. However, in a case where the maximum storage amount has been reached, that is, YES, the process shifts to the next resetting (S54) of another recycled paper sheet storage section (another first recycled paper sheet storage section).
(Resetting of Another First Recycled Paper Sheet Storage Section)
When the printing recycled paper sheet storage section (first recycled paper sheet storage section) 821 illustrated in
In a case where both or any one of the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 823 and 824 have the region in which the printing recycled paper sheet Pr1 can be stored (YES), the process shifts to the setting (S51) of another recycled paper sheet storage section (another first recycled paper sheet storage section), and the printing recycled paper sheet Pr1 is stored in the newly set another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B. However, in a case where there is no region in which the printing recycled paper sheet Pr1 can be stored, that is, in a case where the maximum storage amount has been reached (NO), in any of the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 823 and 824, it is confirmed (S55) whether or not the paper sheet recycling and printing apparatus 1100 receives a manufacturing instruction of the recycled paper sheet Pr2 that is not to be supplied for the printing, and when the manufacturing instruction of the recycled paper sheet Pr2 is not received (NO), the paper sheet recycling section 100 is stopped, and the supply of the printing recycled paper sheet Pr1 is paused. Meanwhile, in a case where the paper sheet recycling and printing apparatus 1100 receives the manufacturing instruction of the recycled paper sheet Pr2 (YES), the process shifts to the supply (S60) of the recycled paper sheet Pr2 that is to be described later and not to be supplied for the printing to the recycled paper sheet storage section.
In addition, in a case where the process shifts to the step of confirmation (S55) of the manufacturing instruction of the recycled paper sheet Pr2 before stopping the paper sheet recycling section 100, not only the paper sheet recycling section 100 is stopped by the above-described flow, but also the paper sheet recycling section 100 is stopped in the following case. For example, in a case where the planned forming quantity of the printing recycled paper sheet Pr1 with respect to the paper sheet recycling section 100 is input into the control section in advance and the planned forming quantity has been reached, the process shifts to the step (S55) of the manufacturing instruction of the recycled paper sheet Pr2 before stopping the paper sheet recycling section 100, and shifts to the stop of the paper sheet recycling section 100. Otherwise, in a case where all of the waste paper sheets Pu that serve as the raw material supplied to the waste paper sheet supply section 100a are consumed, the process shifts to the step of confirming (S55) the manufacturing instruction of the recycled paper sheet Pr2 before stopping the paper sheet recycling section 100, and the paper sheet recycling section 100 is stopped or paused while the waste paper sheet Pu is supplied again.
As described above, since any of the plurality of printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824 provided in the printing recycled paper sheet storage unit 820 is set as another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B to which the printing recycled paper sheet Pr1 is supplied, even when the paper sheet recycling section 100 is continuously operated, the printing recycled paper sheet Pr1 formed by the paper sheet recycling section 100 is supplied to any of the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824, and can be stored therein.
In other words, in the paper sheet recycling section 100 which is illustrated in
In addition, from the plurality of printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 822, 823, and 824, from the printing recycled paper sheet storage section (first recycled paper sheet storage section) except for the printing recycled paper sheet storage section (first recycled paper sheet storage section) 822 set as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A, another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B (printing recycled paper sheet storage section (first recycled paper sheet storage section) 821 in the example of the present embodiment) is set as the printing recycled paper sheet storage section (first recycled paper sheet storage section) to which the printing recycled paper sheet Pr1 is supplied and in which the printing recycled paper sheet Pr1 is stored, and accordingly, it is possible to prevent a case where the taking-out of the printing recycled paper sheet Pr1 transported to the printing section 500 and the supply of the printing recycled paper sheet Pr1 from the paper sheet recycling section 100 overlap each other, that is, a so-called paper sheet complication, and to prevent occurrence of jamming.
Next, the flowchart of
As illustrated in
(Recycled Paper Sheet Storage Amount Confirmation)
The recycled paper sheet storage amount confirmation (S70) in which it is confirmed whether or not the designated storage amount of the recycled paper sheets Pr2 to be discharged is stored in the recycled paper sheet storage section 830 of the storage section 800, is executed. Here, in a case where the recycled paper sheet Pr2 of the designated storage amount is stored in the recycled paper sheet storage section 830 (YES), the process shifts to the next printing section passage (S71).
(Printing Section Passage)
In the printing section passage (S71), the printing section 500 is passed, but the printing is not performed at this time. Then, the recycled paper sheet Pr2 that is not to be printed is discharged to the printed material discharge section 500b.
(Recycled Paper Sheet Pr2 Quantity Confirmation)
In addition, it is confirmed whether or not the designated quantity of the recycled paper sheets Pr2 is discharged to the printed material discharge section 500b in the printing section passage (S71) step by the recycled paper sheet Pr2 quantity confirmation (S72). In a case where, the designated quantity has not been reached (NO), the process shifts to the printing section passage (S71) and is repeated until the designated discharge quantity of the designated recycled paper sheets Pr2 is achieved. However, in a case where the designated quantity has been reached (YES), the discharge of the recycled paper sheet Pr2 to the printed material discharge section 500b is stopped.
In a case where the recycled paper sheet Pr2 is not stored in the recycled paper sheet storage section 830 (NO) in the above-described recycled paper sheet storage amount confirmation (S70), the recycled paper sheet Pr2 is supplied to the recycled paper sheet storage section 830 until reaching the designated quantity of the recycled paper sheets Pr2.
As described above, the paper sheet recycling and printing apparatus 1100 according to the present embodiment can discharge the recycled paper sheet Pr2 that is not to be supplied for the printing to the printed material discharge section 500b provided in the printing section 500. Accordingly, since there is no case where a dedicated discharge section of the recycled paper sheet Pr2 is provided, it is possible to further simplify the configuration of the paper sheet recycling and printing apparatus 1100, and to reduce the apparatus cost.
Further, as illustrated in
As an eighth embodiment, the printing apparatus 2000 provided with the storage section 300 including the recycled paper sheet storage unit 320 will be described. In addition, the printing apparatus 2000 according to the present embodiment has an aspect in which the paper sheet recycling section 100 of the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment is configured as a paper sheet recycling apparatus 2100 that serves as an independent apparatus and is incorporated in a paper sheet recycling and printing system 10000. Therefore, the same reference numerals will be given to the same configuration elements as those of the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment, and the description thereof will be omitted.
More specifically, in the printing apparatus 2000 according to the present embodiment, the printing section 500, the transport section 400, the storage section 300, and the recycled paper sheet supply section 200 have the same reference numerals as those of the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment.
As illustrated in
The discharged printing recycled paper sheet Pr1 or recycled paper sheet Pr2 is transported to the recycled paper sheet insertion port 210a of the recycled paper sheet supply section 200 via the supply transport section 230. Then, the transported recycled paper sheet Pr1 is supplied to and stored in any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 provided in the recycled paper sheet storage unit 320 by the first recycled paper sheet supply means (recycled paper sheet storage and supply means) 221 of the recycled paper sheet supply section 200. Meanwhile, the recycled paper sheet Pr2 that is not to be supplied for the printing is supplied to and stored in the recycled paper sheet storage section (second recycled paper sheet storage section) 600 by the second recycled paper sheet supply means (recycled paper sheet discharge and supply means) 222.
The supply transport section 230 is provided in the recycled paper sheet supply section 200, but is disposed to be detachable from the paper sheet recycling apparatus 2100. In this manner, as the paper sheet recycling apparatus 2100 and the printing apparatus 2000 are configured to be separable at the position of the supply transport section 230, it is possible to easily exchange only the paper sheet recycling apparatus 2100, and to easily perform maintenance and management of the paper sheet recycling and printing system 10000.
In addition, in the printing apparatus 2000 according to the present embodiment, since a flow for supplying the printing recycled paper sheet Pr1 supplied from the paper sheet recycling apparatus 2100 to the recycled paper sheet storage unit 320 and a flow for supplying the recycled paper sheet Pr2 to the recycled paper sheet discharge section (second recycled paper sheet storage section) 600 are the same as those of the flowchart illustrated in

In other words, in the paper sheet recycling and printing system 10000 illustrated in
As a ninth embodiment, the paper sheet recycling apparatus 3000 provided with the storage section 300 including the recycled paper sheet storage unit 320 and the recycled paper sheet discharge section (second recycled paper sheet storage section) 600 will be described. In addition, the paper sheet recycling apparatus 3000 according to the present embodiment has an aspect in which the printing section 500 of the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment is configured as the printing apparatus 3100 that serves as an independent apparatus and is incorporated in the paper sheet recycling and printing system 20000. Therefore, the same reference numerals will be given to the same configuration elements as those of the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment, and the description thereof will be omitted.
More specifically, in the paper sheet recycling apparatus 3000 according to the present embodiment, the paper sheet recycling section 100, the recycled paper sheet supply section 200, the storage section 300, and the transport section 400, are the same configuration elements as those of the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment.
As illustrated in
Between the transport section 400 and the printing apparatus 3100, the new paper sheet Pn or the printing recycled paper sheet Pr1 of the recording target medium discharged from the paper sheet supply section 400a is transported to the paper sheet taking-in section 3100a of the printing apparatus 3100 by the supply transport section 430 provided in the transport section 400.
The supply transport section 430 is disposed separably between the paper sheet recycling apparatus 3000 and the printing apparatus 3100, and can easily exchange the printing apparatus 3100. In other words, in the paper sheet recycling and printing system 20000, the printing apparatus 3100 is an apparatus that is easily applied to an appropriate printing apparatus according to work, for example, from a laser printer to an ink jet printer or a printing apparatus having a faster printing speed, or from a monochrome printer to a color printer.

The paper sheet recycling and printing system 20000 including the paper sheet recycling apparatus 3000 according to the present embodiment may be a paper sheet recycling and printing system in which the recycled paper sheet discharge section (second recycled paper sheet storage section) 600 provided in the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment is provided, the recycled paper sheet Pr2 that is not to be supplied for the printing is stored in the recycled paper sheet discharge section 600, the recycled paper sheet storage section 600 functions as the taking-out section of the recycled paper sheet Pr2, but the storage section 800 according to the seventh embodiment is provided.
In other words, in the paper sheet recycling and printing system 20000 illustrated in
As described above, in the paper sheet recycling and printing apparatus 1000 according to the sixth embodiment, the paper sheet recycling and printing apparatus 1100 according to the seventh embodiment, the paper sheet recycling and printing system 10000 including the printing apparatus 2000 according to the eighth embodiment, and the paper sheet recycling and printing system 20000 including the paper sheet recycling apparatus 3000 according to the ninth embodiment, as the plurality of recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 322, 323, and 324 are provided in the recycled paper sheet storage unit 320 as illustrated in
Furthermore, when one of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 321, 323, and 324 except for the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A, that is, the recycled paper sheet storage section (first recycled paper sheet storage section) 322 in the example of the setting of the present embodiment, or one of other printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 821, 823, and 824 except for the printing recycled paper sheet storage section (first recycled paper sheet storage section) 822, is reset (step S34) as the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A, any of the recycled paper sheet storage sections (first recycled paper sheet storage sections) 323 and 324 further except for another recycled paper sheet storage section (another first recycled paper sheet storage section) 32B to which the printing recycled paper sheet Pr1 formed in the paper sheet recycling section 100 or the paper sheet recycling apparatus 2100 and the recycled paper sheet storage section (another first recycled paper sheet storage section) 321 in the example of the setting of the above-described embodiment, or any of the printing recycled paper sheet storage sections (first recycled paper sheet storage sections) 823 and 824 further except for the printing recycled paper sheet storage section (first recycled paper sheet storage section) 821, is reset as another recycled paper sheet storage section (first recycled paper sheet storage section) 32B. Therefore, when the printing recycled paper sheet Pr1 transported from the predetermined recycled paper sheet storage section (predetermined first recycled paper sheet storage section) 32A to the printing section 500 or the printing apparatus 3100 is taken out, there is no case where the supply of the printing recycled paper sheet Pr1 from the paper sheet recycling section 100 or the paper sheet recycling apparatus 2100 overlaps the taking-out. Therefore, it is possible to prevent occurrence of jamming at the time of paper feeding to the printing section 500 or the printing apparatus 3100.
Further, in the paper sheet recycling section 100, it is possible to form the printing recycled paper sheet Pr1 to be supplied for the printing and the recycled paper sheet Pr2 that is not to be supplied for the printing. Since at least two types of recycled paper sheets (printing recycled paper sheet Pr1 and recycled paper sheet Pr2) are used differently, and in particular, the recycled paper sheet Pr2 is simply used as the recycled paper sheet cut form, and in the paper sheet recycling and printing apparatus 1000 and the paper sheet recycling and printing systems 10000 and 20000 according to the above-described embodiments, the recycled paper sheet discharge section (second recycled paper sheet storage section) 600 is provided, and accordingly, it is possible to easily take out the recycled paper sheet Pr2.
In addition, in the paper sheet recycling and printing apparatus 1100, even when the recycled paper sheet Pr2 is supplied from the transport section 900 to the printing section 500, the taking-out section of the printed material Pp and the recycled paper sheet Pr2 in the apparatus can be used commonly by discharging the paper sheets to the printed material discharge section 500b without printing, and it is possible to provide ease of taking out the paper sheet.
