This application is a U.S. National stage application of International Patent Application No. PCT/JP2017/020662, filed on Jun. 2, 2017, which claims priority under 35 U.S.C. § 119(a) to Japanese Patent Application No. 2016-129816, filed in Japan on Jun. 30, 2016. The entire disclosure of Japanese Patent Application No. 2016-129816 is 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.
However, the method of recycling the waste paper sheet in the apparatuses disclosed in Japanese Unexamined Patent Application Publication Nos. 7-75384, 10-171318, and 2008-33034 forms 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 formed, 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.
In other words, 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.
This is because an abnormal state is determined in the printing apparatus, the printing apparatus is stopped, and the work efficiency remarkably deteriorates. Here, a paper sheet recycling and printing apparatus which prevents complication with the recycled paper sheet which is supplied to the printing apparatus and is already stored therein, that is, so-called occurrence of jamming, while continuously operating the paper sheet recycling apparatus and storing the recycled paper sheet.

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, and a recycled paper sheet storage unit 320 in which the recycled paper sheet Pr is stored. In this example, the recycled paper sheet storage unit 320 includes the plurality of recycled paper sheet storage sections 321, 322, 323, and 324 including the recycled paper sheet storage section 321 to which the recycled paper sheet Pr formed in the paper sheet recycling section 100 is supplied and in which the recycled paper sheet Pr is stored; the recycled paper sheet storage section 322 in which the recycled paper sheet Pr supplied to the printing section 500 is stored; and the recycled paper sheet storage sections 323 and 324 which stand by in a state where the recycled paper sheet Pr is stored, as illustrated in the drawing.
In addition, in 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 is provided with recycled paper sheet transport means 210 (not illustrated in detail) and recycled paper sheet supply means 220. 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 paper sheet Pr which has been recycled is 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 recycled paper sheet Pr inserted into the recycled paper sheet insertion port 210a is transported to the recycled paper sheet supply means 220 by the recycled paper sheet transport means 210. The recycled paper sheet supply means 220 moves such that the recycled paper sheet Pr can be supplied to any of the recycled paper sheet storage sections 321, 322, 323, and 324 provided in the recycled paper sheet storage unit 320 by driving means that serves as the supply switching means (not illustrated), and stores the recycled paper sheet Pr therein. In the present embodiment, an aspect in which the recycled paper sheet Pr is stored in the recycled paper sheet storage section 321 is illustrated.
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 recycled paper sheet Pr 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 321, 322, 323, and 324 in which the recycled paper sheet Pr 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 a 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 321, 322, 323, and 324 in which the recycled paper sheet Pr is stored are disposed by a paper sheet selection command from the printing section 500, and can pick up a desired paper sheet.
The recycled paper sheet Pr supplied from the paper sheet supply section 400a of the transport section 400 or the new paper sheet Pn is taken into the apparatus from a paper sheet taking-in section 500a of the printing section 500, and is discharged to a printed material discharge section 500b as a 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 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 a 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 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 calender 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 calender 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 calender 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 calender 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 recycled paper sheet Pr of a cut form having a predetermined size cut from the sheet S is formed. The cut recycled paper sheet Pr of the cut form is discharged to the recycled paper sheet discharge section 100b illustrated in
The recycled paper sheet Pr formed by the above-mentioned paper sheet recycling section 100 is supplied to any of the recycled paper sheet storage sections 321, 322, 323, and 324 provided in the recycled paper sheet storage unit 320 by the recycled paper sheet supply section 200 and is stored therein, as described in
In this manner, from the plurality of recycled paper sheet storage sections 321, 322, 323, and 324, one recycled paper sheet storage section to which the recycled paper sheet Pr is supplied by the recycled paper sheet supply section 200 and one 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 which is selected from the plurality of recycled paper sheet storage sections 321, 322, 323, and 324 and to which the recycled paper sheet Pr is supplied by the recycled paper sheet supply section 200 is referred to as a second recycled paper sheet storage section 32B. Meanwhile, one recycled paper sheet storage section which is selected from the plurality of recycled paper sheet storage sections 321, 322, 323, and 324 and from which the recycled paper sheet Pr is taken out by the transport section 400 is referred to as a first recycled paper sheet storage section 32A.
(Setting of First Recycled Paper Sheet Storage Section)
When the operation of the paper sheet recycling section 100 is started, firstly, the setting (S10) of the first recycled paper sheet storage section is executed. As described above, the first recycled paper sheet storage section 32A indicates one recycled paper sheet storage section which is selected from the plurality of recycled paper sheet storage sections 321, 322, 323, and 324 and from which the recycled paper sheet Pr is taken out by the transport section 400. In other words, among the recycled paper sheet storage sections 321, 322, 323, and 324, one recycled paper sheet storage sections in which the recycled paper sheet Pr can be transported to the printing section 500, is set in the first recycled paper sheet storage section 32A. In addition, when the operation of the paper sheet recycling section 100 is started, when the 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 Second Recycled Paper Sheet Storage Section)
Next, the setting (S11) of the second recycled paper sheet storage section in which, among the recycled paper sheet storage sections 321, 323, and 324 except for the first recycled paper sheet storage section 32A (recycled paper sheet storage section 322), one recycled paper sheet storage section in which the recycled paper sheet Pr supplied from the recycled paper sheet recycling section 100 and supplied by the recycled paper sheet supply section 200 is stored is set as the second recycled paper sheet storage section 32B, is executed.
Among the recycled paper sheet storage sections 321, 323, and 324 except for the first recycled paper sheet storage section 32A (recycled paper sheet storage section 322), the recycled paper sheet storage section in which the recycled paper sheet Pr is not stored is selected as the second recycled paper sheet storage section 32B. In the present embodiment, the recycled paper sheet storage section 321 is set as the second recycled paper sheet storage section 32B and the recycled paper sheet Pr is supplied.
In addition, when setting the second recycled paper sheet storage section 32B, it is not necessary to select the printing recycled paper sheet storage section in which there is no recycled paper sheet Pr. For example, in a case where the recycled paper sheet storage section which has already reached the maximum storage amount of the recycled paper sheet Pr has been excluded from options, and further, there is no recycled paper sheet storage section in which there is no recycled paper sheet Pr, even when the recycled paper sheet Pr is stored, it is possible to select the recycled paper sheet storage section having a region in which the new recycled paper sheet Pr can be stored. In the paper sheet recycling and printing apparatus 1000 illustrated in the present embodiment, in order to supply the recycled paper sheet Pr to the printing recycled paper sheet storage section 321 as illustrated in
(Recycled Paper Sheet Supply)
When the second recycled paper sheet storage section is set (S11), the supply (S12) of the recycled paper sheet from the recycled paper sheet supply means 220 of the recycled paper sheet supply section 200 to the set second recycled paper sheet storage section 32B, is executed.
(Recycled Paper Sheet Storage Amount Detection)
When the recycled paper sheet Pr is supplied to the second recycled paper sheet storage section 32B, the recycled paper sheet storage among detection (S13) in the second recycled paper sheet storage section 32B is performed. In the recycled paper sheet storage amount detection (S13), in a case where the maximum storage amount is not satisfied, that is, NO, the 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 the second recycled paper sheet storage section.
(Resetting of Second Recycled Paper Sheet Storage Section)
When the recycled paper sheet storage section 321 illustrated in
In a case where both or any one of the recycled paper sheet storage sections 323 and 324 have the region in which the recycled paper sheet Pr can be stored (YES), the process shifts to the setting (S11) of the second recycled paper sheet storage section, and the recycled paper sheet Pr is stored in the newly set second recycled paper sheet storage section 32B. However, in a case where there is no region in which the recycled paper sheet Pr 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 323 and 324, the paper sheet recycling section 100 is stopped, and the supply of the recycled paper sheet Pr is paused.
In addition, stopping of paper sheet recycling section 100 is not only stopping of the paper sheet recycling apparatus according to the above-described flow, but also stopping of the paper sheet recycling apparatus in the following cases. For example, in a case where the planned forming quantity of the recycled paper sheet Pr 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 paper sheet recycling apparatus is stopped. 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 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 321, 322, 323, and 324 provided in the recycled paper sheet storage unit 320 is set as the second recycled paper sheet storage section 32B to which the recycled paper sheet Pr is supplied, even when the paper sheet recycling section 100 is continuously operated, the recycled paper sheet Pr formed by the paper sheet recycling section 100 is supplied to any of the 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 321, 322, 323, and 324, from the recycled paper sheet storage section except for the recycled paper sheet storage section (recycled paper sheet storage section 322 in the example of the present embodiment) set as the first recycled paper sheet storage section 32A, the second recycled paper sheet storage section 32B (recycled paper sheet storage section 321 in the example of the present embodiment) is set as the recycled paper sheet storage section to which the recycled paper sheet Pr is supplied and in which the recycled paper sheet Pr is stored, and accordingly, it is possible to prevent a case where the taking-out of the recycled paper sheet Pr transported to the printing section 500 and the supply of the recycled paper sheet Pr from the paper sheet recycling section 100 overlap each other, that is, a so-called paper sheet complication, and to prevent occurrence of jamming.

(Printing Paper Sheet Selection)
As illustrated in
(Selection Information Acquisition of First Recycled Paper Sheet Storage Section)
When the recycled paper sheet Pr is selected (YES) in the printing paper sheet selection (S20), the selection information acquisition (S21) of the first recycled paper sheet storage section is executed, and the information on which one of the recycled paper sheet storage sections 321, 322, 323, and 324 is set as the first recycled paper sheet storage section 32A is acquired.
As described in
(Recycled Paper Sheet Storage Amount Confirmation)
From the information acquired in the selection information acquisition (S21) of the first recycled paper sheet storage section, that is, the information indicating that the first recycled paper sheet storage section 32A is the recycled paper sheet storage section 322, the recycled paper sheet storage amount confirmation (S22) for confirming the presence or absence of the recycled paper sheet Pr of the recycled paper sheet storage section 322 is performed. When it is confirmed that at least one recycled paper sheet Pr is stored (YES), the process shifts to the next recycled paper sheet taking-out.
(Recycled Paper Sheet Taking-Out)
The recycled paper sheet taking-out (S23) in which the recycled paper sheet Pr is taken out from the 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 recycled paper sheet Pr transported to the paper sheet taking-in section 500a, and the recycled paper sheet Pr 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 (S22), in a case where it is confirmed that the recycled paper sheet Pr is not stored (NO) in the first recycled paper sheet storage section 32A in which the recycled paper sheet Pr is confirmed in the selection information acquisition (S21) of the first recycled paper sheet storage section in the previous step, the resetting (S24) of the first recycled paper sheet storage section 32A is performed.
(Resetting of First Recycled Paper Sheet Storage Section)
When it is confirmed that the recycled paper sheet Pr is not stored in the recycled paper sheet storage section 322 set in the first recycled paper sheet storage section 32A, the resetting (S24) of the first recycled paper sheet storage section is executed, and except for the recycled paper sheet storage section 321 set in the above-described second recycled paper sheet storage section 32B, any of the recycled paper sheet storage sections 323 and 324 provided in the recycled paper sheet storage unit 320 is set as the first recycled paper sheet storage section 32A again.
In addition, as described with reference to the above-described
Regarding which one of the recycled paper sheet storage sections 323 and 324 is to be set as the first recycled paper sheet storage section 32A, the invention is not particularly limited as long as the recycled paper sheet Pr is stored. For example, the recycled paper sheet storage section with a large storage amount of the recycled paper sheets Pr may be selected, or may be selected and instructed by the operator (person). In addition, although not illustrated, in a case where the recycled paper sheet Pr is not stored in all of the 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 first recycled paper sheet storage section 32A is set by the resetting (S24) of the first recycled paper sheet storage section, the process shifts to the selection information acquisition (S21) of the first recycled paper sheet storage section, and the steps after the recycled paper sheet storage amount confirmation (S22) are executed.
Meanwhile, in a case where the recycled paper sheet Pr is not selected (NO) in the printing paper sheet selection (S20), 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 (S30) for confirming the presence or absence of the new paper sheet Pn stored in the paper sheet storage section 310, is performed. When it is confirmed (YES) that the new paper sheet Pn is stored in the new paper sheet storage amount confirmation (S30), the taking-out (S31) 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 (S32). 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 (S22) step in the flow of selecting the recycled paper sheet Pr 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 (S30) 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 321, 322, 323, and 324 are provided in the recycled paper sheet storage unit 320 as illustrated in
