DETAILED DESCRIPTION OF THE INVENTION

[0009] 1. Sheet recycling system configuration As shown in FIG. 1, the sheet recycling system 1 according to the embodiment includes a sheet recycling device 11, a terminal device 10, and a server 60.

[0010] These devices that make up the sheet recycling system 1 can communicate with each other via a network NW. The network NW may be a LAN (Local Area Network), which is a communication network within a limited area such as a premises, or a WAN (Wide Area Network), which is the Internet. Furthermore, each of these devices is assigned a unique communication address, for example, an IP address (Internet Protocol Address), and communication can be performed by specifying the IP address of the communication destination. These devices can communicate using protocols such as HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure).

[0011] The terminal device 10 is, for example, a smartphone, a tablet terminal, a computer, etc. The terminal device 10 includes a control unit 10a, a communication unit 10b, a storage unit 10c, and an input / output unit 10d. The control unit 10a comprehensively controls each unit of the terminal device 10. The control unit 10a is configured to include a CPU (Central Processing Unit). The CPU is also called a processor.

[0012] The storage unit 10c includes a memory such as a flash ROM (Read Only Memory), which is a rewritable nonvolatile memory, and a RAM (Random Access Memory), which is a volatile memory. The control unit 10a reads out a program stored in the flash ROM of the storage unit 10c and executes it using the RAM of the storage unit 10c as a working area. The storage unit 10c of the terminal device 10 also stores a web browser, etc. The control unit 10a can read out the web browser from the storage unit 10c and execute it.

[0013] The communication unit 10b of the terminal device 10 includes a circuit capable of communicating with the network NW wirelessly or via a wired connection. The communication unit 10b can communicate with other devices constituting the sheet recycling system 1 via the network NW. Although the terminal device 10 transmits and receives data to and from a communication destination using the communication unit 10b, the following description will omit the transmission and reception using the communication unit 10b for the sake of simplicity. Also, the communication unit 10b communicates via the network NW, but the following description will omit the transmission and reception using the network NW.

[0014] The input / output unit 10d of the terminal device 10 is a user interface, such as a touch panel display, and includes a display panel serving as an output unit that displays various information, and a detection panel serving as an input unit. The detection panel is configured to be overlaid on the display panel, and detects the operation of a person's finger using a method such as a capacitance method, a resistive film method, or an optical method. In the input / output unit 10d, the input unit may be a keyboard or a mouse, and the output unit may be a stand-type liquid crystal display.

[0015] The server 60 includes a server control unit 60a, a server communication unit 60b, a server storage unit 60c, and a server input / output unit 60d. These components of the server 60 are almost the same as the components of the terminal device 10 described above, so a description of the same components will be omitted and the explanation will focus on the differences.

[0016] The server storage unit 60c of the server 60 also stores various web pages. In response to a request from another device, the server control unit 60a can read and provide a web page from the server storage unit 60c. At this time, the server control unit 60a can also calculate and provide values ​​requested by the other device. Note that web pages are written in, for example, a markup language. In this way, the server 60 also functions as a so-called Web server. In this case, the other devices function as so-called Web clients.

[0017] When the server 60 sends and receives data to and from the communication destination, it does so via the network NW using the server communication unit 60b. However, as in the case of the terminal device 10, the following description will omit the sending and receiving via the network NW using the server communication unit 60b.

[0018] The sheet recycling device 11 has a sheet recycling board 88. The sheet recycling board 88 is configured to include a sheet recycling control unit 11a, a sheet recycling communication unit 11b, a sheet recycling storage unit 11c, and a sheet recycling input / output unit 11d. These components of the sheet recycling device 11 are almost the same as those of the terminal device 10 described above, so a description thereof will be omitted.

[0019] When the sheet regenerating device 11 sends and receives data to and from the communication destination, it does so via the network NW using the sheet regenerating communication unit 11b. However, as in the case of the terminal device 10, the following description will omit the sending and receiving via the network NW using the sheet regenerating communication unit 11b.

[0020] 2. Structure of the sheet recycling device As shown in Fig. 2, the sheet recycling device 11 is a device that recycles raw materials such as waste paper M into single-sheet shaped sheets S in a so-called dry method. The recycling of sheets S in the sheet recycling device 11 is also referred to as manufacturing, and recycling into sheets S is also referred to as papermaking. The raw materials may contain various fibers and various fiber materials, but the following description will be given using waste paper M as an example. In the embodiment, the dry method means that the recycling of waste paper M into sheets S is carried out in air such as the atmosphere, rather than in a liquid.

[0021] In the following, the waste paper M will be described as moving from upstream to downstream in the sheet recycling device 11 while sequentially changing form from fine fragments P1, first sorted material P2, first pile V1, second pile V2, mixture V3, first web W1, second web W2, and sheet S. The sheet recycling device 11 is configured by arranging, from upstream to downstream, components such as a shredding section 12, a defibrating section 71, a sorting section 72, a first web forming section 73, a rotating body 76, an additive supply section 77, a mixing section 78, a deposition section 79, a second web forming section 80, a humidifying section 83, a pressurizing and heating section 84, a cutting section 85, a tray 86, and a sensor 87, as the waste paper M to sheets S move.

[0022] Furthermore, the sheet recycling device 11 is configured to include the above-mentioned sheet recycling board 88. The sheet recycling control unit 11a mounted on the sheet recycling board 88 can read and execute programs such as firmware stored in the sheet recycling storage unit 11c, and control each part of the sheet recycling device 11.

[0023] In the shredding section 12 of the sheet recycling device 11, the waste paper M accumulated in the accumulation section 90 is dropped into a shredding hopper 92 and shredded by a pair of shredding blades 93 into shredded pieces P1. The fine fragments P1 are dropped into a hopper 70 of the sheet recycling device 11, defibrated in a defibrating unit 71, and transported to a sorting unit 72. The defibrating unit 71 is a so-called impeller mill, which untangles the fibers of the fine fragments P1 and defibrates them. The defibrating unit 71 can also generate an airflow toward the sorting unit 72, and transports the defibrated fine fragments P1 to the sorting unit 72.

[0024] The sorting unit 72 is configured, for example, with a rotatable cylindrical metal sieve. The sorting unit 72 passes the first sorted material P2, which is fibers or particles smaller than the mesh size of the sieve, and drops it onto the mesh belt 74 of the first web forming unit 73. On the other hand, the sorting unit 72 returns the second sorted material P3, which is fibers or particles larger than the mesh size of the sieve, to the defibrating unit 71 again to be defibrated.

[0025] The first sorted material P2 that has passed through the sorting section 72 is sucked into the first suction section 75 of the first web forming section 73 below, and is deposited on the mesh belt 74, becoming a first deposit V1. The first pile V1 is transported by the mesh belt 74 and cut into pieces of a predetermined length by the rotor 76 to become the second pile V2. The additive supply unit 77 has an additive cartridge (not shown) that contains the additive R. The additive supply unit 77 adds the additive R to the second pile V2. The additive cartridge is a consumable item and is supplied by the manufacturer of the sheet recycling device 11 or the like.

[0026] The additive R includes a resin such as a thermoplastic resin or a thermosetting resin as a binder. These resins can be melted by heating to bond multiple fibers together. The additive R can also include a colorant, an agglomeration inhibitor to suppress agglomeration of the fibers and resin, and a flame retardant. The color of the colorant may be, for example, yellow, magenta, cyan, white, plain colorless, etc. In addition, by adjusting the types and amounts of components contained in the additive R, the strength and thickness of the recycled sheet S can be changed. The sheet recycling control unit 11a of the sheet recycling board 88 can detect the remaining amount of additive R in the additive cartridge by a remaining amount sensor (not shown).

[0027] The second deposit V2 and the additive R are mixed into a mixture V3 by a mixer 78. The mixer 78 is, for example, a blower, and can generate an airflow toward the depositing section 79. The deposition unit 79 is configured, for example, with a rotatable cylindrical metal sieve. The mixture V3 conveyed to the deposition unit 79 is sucked through the openings in the mesh of the sieve of the deposition unit 79 into the second suction unit 82 of the second web forming unit 80 below, allowing it to fall evenly.

[0028] The dropped mixture V3 is deposited on the mesh belt 81 of the second web forming section 80 and becomes the first web W1. The first web W1 transported by the mesh belt 81 has its moisture content adjusted by the humidifying section 83, and is then heated and pressurized by the pressurizing and heating section 84 to become the second web W2. The pressurizing and heating unit 84 is configured to pressurize the first web W1 and then heat it, for example. The pressurizing and heating unit 84 is configured by, for example, a pair of calender rollers that pressurize the first web W1 and a pair of heating rollers.

[0029] The binder contained in the first web W1 melts and bonds the fibers together by the pressurizing and heating section 84. At this time, the moisture contained in the first web W1 evaporates after the temperature rises, and the thickness of the first web W1 decreases, thereby increasing the fiber density. The second web W2 is cut into sheets S of a predetermined size, such as A4, by a cutting section 85 and stored in a tray 86.

[0030] The tray 86 is provided with a sensor 87 capable of detecting the weight of the sheet S. The sensor 87 is a weight sensor, such as a so-called load cell or pressure sensor. The sheet recycling control unit 11a of the sheet recycling board 88 can detect the weight of the sheets S using the sensor 87 and calculate the number of sheets S that have been recycled.

[0031] As will be described later, there are multiple types of sheets S to be recycled, which differ in size, color, strength, thickness, etc. Specifically, the weight of each sheet S based on these combinations is stored in the sheet recycling storage unit 11c. The sheet recycling control unit 11a can identify the type of sheet S and calculate the number of recycled sheets S based on the weight of the sheet S detected by the sensor 87 and the weight of each sheet S read from the sheet recycling storage unit 11c. At this time, the sheet recycling control unit 11a may identify the average or most common type of sheet S in the recycling and calculate the number.

[0032] 3. Control method of sheet regeneration system A control method for the sheet recycling system 1 will be described with reference to Fig. 3. In practice, the control unit 10a of the terminal device 10, the server control unit 60a of the server 60, and the sheet recycling control unit 11a of the sheet recycling board 88 of the sheet recycling device 11 each perform their own processing. For the sake of brevity, the following description will omit the execution of each control unit.

[0033] As described above, the sheet recycling device 11 recycles sheets S from waste paper M (S101), and transmits sheet recycling information related to the recycling of sheets S to the server 60 (S102). The server 60 stores the received sheet recycling information in the server storage unit 60c. For example, the sheet recycling information is the amount of sheets S recycled by the sheet recycling device 11, and includes information on the number of sheets S recycled, which is the sheet recycling amount. Furthermore, for example, the sheet recycling information may include the amount of water consumed by the humidifying unit 83 of the sheet recycling device 11. Furthermore, for example, the sheet recycling information may include the power consumption when the sheet recycling device 11 recycles the sheets S from the waste paper M.

[0034] It is preferable that the sheet recycling device 11 transmits the sheet recycling information even without a request from the server 60, that is, it transmits the sheet recycling information by so-called push transmission. The server 60 does not need to request the sheet recycling information by monitoring the timing when the sheet recycling device 11 regenerates the sheet S. The sheet reproduction device 11 stores the URL (Uniform Resource Locator) of the server 60 in a sheet reproduction storage unit 11c. The sheet reproduction device 11 can read and access the URL of the server 60 from the sheet reproduction storage unit 11c and communicate with the server 60. The same applies to the terminal device 10. At this time, the sheet recycling device 11 may execute a stored communication application to communicate with the server 60. The sheet recycling device 11 may also communicate with the server 60 using the acquired web page. The same applies to the terminal device 10.

[0035] The user of the terminal device 10 operates the input / output unit 10d to request display information from the terminal device 10 to the server 60 (S103). The server 60 generates display information based on the sheet regeneration information read from the server storage unit 60c (S104) and transmits the display information to the terminal device 10 (S105).

[0036] At this time, in response to a request from the terminal device 10, the server 60 can refer to the server storage unit 60c, perform calculations in response to the request, and generate display information. The terminal device 10 displays the received display information through the input / output unit 10d (S106). The user of the terminal device 10 can visually confirm the requested display information through the input / output unit 10d.

[0037] The terminal device 10 stores an application for displaying display information in the storage unit 10c, and the terminal device 10 reads out and executes the application from the storage unit 10c based on a user's operation. The display information is configured, for example, as a web page. The terminal device 10 can acquire the web page from the server 60 and display it on the screen using the input / output unit 10d.

[0038] It should be noted that the sheet regenerating device 11 may display the display information instead of the terminal device 10. In this case, the user of the sheet recycling device 11 operates the sheet recycling input / output unit 11d to request display information from the sheet recycling device 11 to the server 60. The server 60 generates display information and transmits it to the sheet recycling device 11. The sheet recycling device 11 can display the received display information using the sheet recycling input / output unit 11d. The user of the sheet regenerating device 11 can visually confirm the requested display information through the sheet regenerating input / output unit 11d.

[0039] 4.Display information 4 to 7 show "first screen SA" to "fourth screen SD" that are respectively displayed by the terminal device 10 via the input / output unit 10d based on the received display information "first display information SSA" to "fourth display information SSD." Each screen is also a web page acquired from the server 60. The same applies to the case where the sheet recycling device 11 displays the information.

[0040] As described above, the terminal device 10 requests display information from the server 60. When making the request, the user of the terminal device 10 operates the input / output unit 10d. Specifically, from the menu displayed to the right of the "first screen SA" shown in FIG. 4, the user specifies "Results SA2," which indicates monthly results, as the subject to be "displayed" in the "first display information SSA," and specifies "FY2023SA3," which is the "fiscal year 2023" from April 2023 to March 2024, as the "target period," which is the predetermined period to be displayed. In addition, the user of the terminal device 10 operates the input / output unit 10d and, from the menu displayed at the top of the "first screen SA", specifies the "target number TA1", which is the value related to the number of sheets S to be reproduced, as "20,000 sheets" as the "target value" related to the reproduction of sheets S. The terminal device 10 transmits the specified "Actual result SA2", "FY2023SA3", and "Target number TA1" to the server 60 and requests display information.

[0041] As described above, the sheet recycling device 11 can detect the weight of the recycled sheets S using the sensor 87 and calculate the number of recycled sheets S. The sheet recycling device 11 sequentially transmits the calculated number of sheets S to the server 60 as sheet recycling information related to the recycling of the sheets S. In the example of FIG. 4, the sheet recycling device 11 identifies the type of sheets S that are averagely or most frequently recycled, and calculates the number of recycled sheets S based on the identified type of sheets S.

[0042] The server 60 sequentially receives sheet recycling information from the sheet recycling device 11 and stores it in the server storage unit 60c. The server 60 can read the sheet recycling information from the server storage unit 60c and calculate the "monthly recycled sheet number SA1," which is the number of recycled sheets S per month corresponding to the received "FY2023SA3" and "actual result SA2." The server 60 can also calculate the "average number of sheets per month UA1," which is the average number of sheets S recycled per month. In the example of Fig. 4, the current time is the middle, end, or beginning of September, and the "average number of sheets per month UA1" from April to September is shown.

[0043] The server storage unit 60c of the server 60 stores, for example, a first coefficient that converts the amount of carbon dioxide (CO2) generated when one of the predetermined sheets S is recycled. The server memory unit 60c also stores a second coefficient that converts the amount of CO2 generated when producing one sheet of paper corresponding to a specified sheet S using a general wet papermaking method that is different from the sheet recycling device 11 of this embodiment.

[0044] The server 60 reads the first coefficient from the server storage unit 60c, and can calculate the first amount of CO2 generated in the sheet recycling device 11 according to the "target number TA1" of the received sheets S, which is "20,000 sheets." In addition, the server 60 can read the second coefficient from the server memory unit 60c and calculate the second amount of CO2 generated in accordance with the ``target number TA1'' of the received sheets S, which is ``20,000 sheets,'' in a typical wet papermaking method. In these cases, the server 60 simply multiplies each coefficient by the "target number TA1."

[0045] The server 60 can calculate the CO2 reduction amount as the "environmental effect value TA3" by subtracting the first CO2 amount from the second CO2 amount. This CO2 reduction amount is the amount of CO2 that can be reduced when the number of sheets S corresponding to the "target number of sheets TA1" is recycled by the sheet recycling device 11 of this embodiment compared to when paper is produced by a general wet papermaking method, and is referred to as the carbon dioxide reduction amount or the CO2 emission reduction amount. In this way, the server 60 can convert the amount of CO2 reduction by the sheet recycling device 11 into an "environmental effect value TA3" from the "target number TA1" of the received sheets S. Here, the amount of CO2 reduction, which is the "environmental effect value TA3", is shown as "XXX kg". As will be described later, the environmental effect value that can be converted by the server 60 can include at least one of the amount of CO2 reduction, the amount of wood reduction, and the amount of water reduction.

[0046] As described above, the server 60 can generate the "monthly recycled sheet count SA1" based on the sheet recycling information received from the sheet recycling device 11, the "actual results SA2" and "FY2023SA3" received from the terminal device 10, etc. Then, the server 60 can include the "monthly recycled sheet count SA1" as graph information in the "first display information SSA" and transmit it to the terminal device 10. At this time, the "target number line GA1" indicating the received "target number TA1" can be included in the graph information of the "monthly recycled number of sheets SA1." Furthermore, the server 60 can also include the "monthly average number UA1" in the "first display information SSA" and transmit it to the terminal device 10.

[0047] Furthermore, the server 60 can predict and calculate the number of recycled sheets S for a future period using the "monthly average number UA1" generated based on the sheet recycling information. Specifically, for the future period from October onwards within the specified period "FY2023SA3", the server 60 can use the "average number of sheets per month UA1" to determine the number of sheets S to be reproduced from October onwards, and include this in the display information and send it to the terminal device 10.

[0048] In this way, the server 60 can convert the received “target number TA1” into an “environmental effect value TA3”, include it in the “first display information SSA” together with the above-mentioned information, and transmit it to the terminal device 10. The terminal device 10 receives the "first display information SSA" including these, and can display it as the "first screen SA" by the input / output unit 10d.

[0049] Furthermore, the user of the terminal device 10 can operate the input / output unit 10d to specify "350 kg" as the "target environmental effect value TA2" from the menu displayed at the top of the "first screen SA." The "target environmental effect value TA2" is a "target value" for recycling the sheet S, and is the amount of reduced CO2, which is a value related to the environmental effect value that can be reduced when recycling the sheet S compared to a typical wet papermaking method. As shown in FIG. 4, only one of the "target number TA1" and the "target environmental effect value TA2" can be designated by using so-called radio buttons. The terminal device 10 can transmit the designated "target environmental effect value TA2" to the server 60 and request display information.

[0050] In this case, the server 60 can use the first coefficient to calculate a third amount of CO2 generated per sheet of the predetermined number of recycled sheets S. The server 60 can also use the second coefficient to calculate a fourth amount of CO2 generated per sheet of paper corresponding to the predetermined sheet S produced by a general wet papermaking method. The server 60 subtracts the third CO2 amount from the fourth CO2 amount. As a result, the server 60 can calculate the CO2 reduction amount per sheet S when the sheet S is recycled by the sheet recycling device 11 of this embodiment compared to when paper is produced by a general wet papermaking method.

[0051] The server 60 can convert this into the "number of recycled sheets TA4" by dividing the calculated CO2 reduction amount per sheet S by the received "target environmental effect value TA2" of "350 kg" CO2 reduction amount. The "number of recycled sheets TA4" is the number of recycled sheets S that must be recycled to reach the "target environmental effect value TA2" of "350 kg" CO2 reduction amount. In this way, the server 60 can convert the target amount of CO2 reduction, which is the received "target environmental effect value TA2," into the number of sheets S to be recycled as the "number of recycled sheets TA4." Here, the number of sheets S to be recycled, which is the "number of recycled sheets TA4," is shown as "XXXX sheets."

[0052] The server 60 can convert the received "target environmental effect value TA2" into "number of recycled sheets TA4", include it in "first display information SSA", and transmit it to the terminal device 10. The terminal device 10 receives the "first display information SSA" including the "number of recycled sheets TA4" and can display it as the "first screen SA" by the input / output unit 10d. In this case, the target value is the "target environmental effect value TA2", which is a value related to the environmental effect value, and the server 60 converts the received target value into the "number of recycled sheets TA4", which is the number of recycled sheets S, and can include the "number of recycled sheets TA4" in the display information and send it to the terminal device 10. The target value can be a target environmental effect value relating to at least one of the amount of carbon dioxide reduction (the amount of CO2 reduction), the amount of wood reduction, and the amount of water reduction. Based on the received target environmental effect value, the server 60 can convert it into the number of recycled sheets S instead of the above-mentioned environmental effect value, include it in the display information, and send it to the terminal device 10.

[0053] Next, Fig. 5 shows the "second screen SB" which is a screen displaying the "second display information SSB". Below, the differences from the "first screen SA" which displays the "first display information SSA" in Fig. 4 will be mainly explained. The user of the terminal device 10 operates the input / output unit 10d to specify the "model" to be targeted for the sheet recycling device 11, "model MB1," from the menu displayed in the upper left position of the "second screen SB" shown in FIG. 5. Here, "model MB1" is a model name such as "YYY." The sheet recycling device 11 can regenerate multiple types of sheets S for each model. Next to the specified "Target number of sheets TB1" of "20,000 sheets," a "pull-down menu MB2" is displayed that allows the selection of "sheet type TB5," which is the type of sheet S that corresponds to "model MB1." "Sheet type TB5" is the type of sheet S that can be recycled by the model name "YYY." Here, it is assumed that "blank paper, plain paper, A4" is selected for "sheet type TB5."

[0054] As described above, when the sheet recycling device 11 recycles the sheet S, it adds the additive R from the additive supply unit 77. By adjusting the types and amounts of components such as colorants and resins contained in the additive R, it is possible to change the color, strength, thickness, etc. of the sheet S to be recycled. In addition, the cutting unit 85 can recycle the sheet S into a predetermined size. In the example of FIG. 5 where "sheet type TB5" is "blank paper, plain paper, A4", the color of the sheet S to be recycled is set to white, the strength and thickness to plain paper level, and the size to A4.

[0055] The terminal device 10 sends the "target number TB1", which is a value related to the number of sheets S to be reproduced, and the "sheet type TB5", which is sheet specification information specifying the type of sheet S, to the server 60, and requests display information including the "environmental effect value TB3". The "sheet type TB5" of the sheet S corresponds to the "model MB1" of the sheet recycling device 11. In other words, the "sheet type TB5" is information that specifies the type of sheet S that can be recycled in accordance with the "model MB1" specified for the sheet recycling device 11.

[0056] For example, the server 60 can calculate the fifth amount of CO2 generated in accordance with the "target number of sheets TB1" of "20,000 sheets" when the "sheet type TB5" is "blank paper, plain paper, A4" using the following formula: Recycled weight of sheet S = "Target number of sheets TB1" x α 5. CO2 amount = recycled weight of sheet S × β α is a coefficient based on the "sheet type TB5" and the like, and β is a coefficient based on the production capacity, power consumption, and the like determined by the sheet recycling device 11. α is determined, for example, according to the color, strength, thickness, size, and the like of the sheet S to be recycled. In this case, the value of α increases as the strength, thickness, or size increases. In addition, the color of the sheet S to be recycled is related to the type of colorant, and can be a factor that changes the value of α, just like the strength, etc.

[0057] The server 60 stores in the server storage unit 60c α corresponding to the "sheet type TB5" and β corresponding to the "model MB1" of the sheet recycling device 11, and is able to perform the above calculations. α×β can also be a third coefficient, following the first and second coefficients described above. The server 60 reads the third coefficient, α×β, from the server storage unit 60c, and can calculate the fifth amount of CO2 generated by the sheet recycling device 11 according to the "target number TB1" of 20,000 sheets of sheets S whose "sheet type TB5" corresponds to "blank paper, plain paper, A4." α×β is also the amount of CO2 generated per recycled sheet of sheets S corresponding to "sheet type TB5."

[0058] Furthermore, the server storage unit 60c also stores a fourth coefficient that converts the amount of CO2 emitted when one sheet of paper corresponding to "sheet type TB5" is produced using a typical wet papermaking method. The server 60 reads the fourth coefficient from the server memory unit 60c and can calculate the sixth amount of CO2 generated by a typical wet papermaking method based on the "target number of sheets TB1" of "20,000 sheets" for paper whose "sheet type TB5" corresponds to "blank paper, plain paper, A4."

[0059] The server 60 can calculate the amount of CO2 reduction by the sheet recycling device 11 as the "environmental effect value TB3" by subtracting the fifth amount of CO2 from the sixth amount of CO2. This CO2 reduction amount is the amount of CO2 that can be reduced when the sheet S is recycled using the sheet recycling device 11 of this embodiment, compared to when the number of sheets equivalent to the "target number of sheets TB1" is produced using a general wet papermaking method, when the "sheet type TB5" is "white paper, plain paper, A4". In this way, when the "sheet type TB5" is "blank paper, plain paper, A4," the server 60 can convert the "target number of sheets TB1" of sheets S into the amount of CO2 reduction as the "environmental effect value TB3." In other words, the server 60 can convert the "environmental effect value TB3" based on the received "target number of sheets TB1" and "sheet type TB5."

[0060] The server 60 transmits the converted "environmental effect value TB3" to the terminal device 10, including the converted "second display information SSB". The terminal device 10 receives the "second display information SSB" including the "environmental effect value TB3" and can display it as the "second screen SB." Here, the terminal device 10 displays the amount of CO2 reduction, which is the "environmental effect value TB3," as "XXX kg." Note that the "Actual results SB2" and "FY2023SB3", "Number of recycled sheets per month SB1", "Average number of sheets per month UB1", etc. in Figure 5 are the same as those in Figure 4 above, so explanations will be omitted. The "Target number line GA1" may differ depending on the "sheet type TB5", so it is not shown in Figure 5, but it can also be displayed when the "sheet type TB5" is "blank paper, plain paper, A4", for example.

[0061] In addition, the terminal device 10 can specify the "target environmental effect value TB2," which is a value related to the environmental effect value that can be reduced when recycling the sheet S, as "350 kg" as the "target value" related to the recycling of the sheet S, select the "sheet type TB6," send it to the server 60, and request display information. Specifically, the "target environmental effect value TB2" is the amount of CO2 that can be reduced when recycling sheet S using the sheet recycling device 11 compared to a typical wet papermaking method when the "sheet type TB6" is "white paper, plain paper, A4." It is assumed that "sheet type TB6" is selected from "pull-down menu MB3", and in this example, "blank paper, plain paper, A4" is selected.

[0062] The server 60 can use the third coefficient, which is α×β, to calculate the seventh amount of CO2 generated per recycled sheet of sheet S when the specified "sheet type TB6" is "white paper, plain paper, A4." The server 60 can also use the fourth coefficient to calculate the eighth amount of CO2 generated per sheet of paper manufactured by a general wet papermaking method when the "sheet type TB6" is "white paper, plain paper, A4." The server 60 subtracts the seventh CO2 amount from the eighth CO2 amount. As a result of this subtraction, the server 60 can calculate the CO2 reduction amount per sheet when the sheet S is recycled by the sheet recycling device 11 of this embodiment compared to when the paper is produced by a general wet papermaking method when the "sheet type TB6" is "white paper, plain paper, A4."

[0063] The server 60 can convert this into the "number of recycled sheets TB4" by dividing the calculated CO2 reduction amount per sheet by the received "target environmental effect value TB2," which is the amount of CO2 reduction "350 kg." The "number of recycled sheets TB4" is the number of recycled sheets S required to reach the "target environmental effect value TB2" of reduced CO2 emissions of "350 kg" in the sheet recycling device 11 when the "sheet type TB6" is "blank paper, plain paper, A4."

[0064] In this way, the server 60 can convert the amount of CO2 reduction, which is the "target environmental effect value TB2," into the number of sheets S to be recycled as the "number of recycled sheets TB4" according to the specified "sheet type TB6." Here, when the "sheet type TB6" is "blank paper, plain paper, A4," the "number of recycled sheets TB4," which is the number of sheets S to be recycled, is shown as "XXXX sheets." That is, the server 60 can convert the received "sheet type TB6" and "target environmental effect value TB2" into "number of recycled sheets TB4" and include the "number of recycled sheets TB4" in the display information and send it to the terminal device 10.

[0065] Next, Fig. 6 shows the "third screen SC" which is a screen displaying the "third display information SSC." The following mainly explains the differences from the "first screen SA" which displays the "first display information SSA" in Fig. 4. The user of the terminal device 10 operates the input / output unit 10d, and from the menu displayed to the right of the "third screen SC" shown in Figure 6, specifies "Cumulative SC2", which indicates the monthly cumulative total, as the object to be "displayed" in the "third display information SSC", and specifies "CY2023SC3", which is the "calendar year 2023" from January 2023 to December 2023, as the "target period", which is the specified period to be displayed. The terminal device 10 transmits the specified "cumulative SC2" and "CY2023SC3" to the server 60 and requests display information.

[0066] The server 60 can read the sheet recycling information from the server memory unit 60c and calculate the "monthly cumulative recycled sheet count SC1," which is the cumulative recycled number of sheets S per month corresponding to the received "CY2023SC3" and "cumulative SC2." The server 60 can include the "monthly cumulative number of recycled sheets SC1" as graph information in the "third display information SSC" and transmit it to the terminal device 10.

[0067] Furthermore, the server 60 can calculate the "average number of sheets recycled per month UC1," which is the average number of sheets S recycled per month, the "predicted number of sheets recycled for this month UC2," which is the predicted number of sheets S recycled for the current month, and the "predicted environmental effect value for this month UC3," which is the predicted environmental effect value for sheets S for the current month, from the "cumulative number of sheets recycled per month SC1," which includes past data. The server 60 can tally up the past "cumulative number of recycled sheets per month SC1" and predict and calculate the "predicted number of sheets for this month UC2" and the "predicted environmental effect value for this month UC3." In the example of FIG. 6, the current time is the middle of November, the end of November, or the beginning of December, and the current month is November. The server 60 may calculate the "predicted environmental effect value for this month UC3" using the "average number of sheets per month UC1."

[0068] The server 60 also aggregates the past "monthly cumulative recycled sheet count SC1" based on the sheet recycling information, and can predict and calculate the predicted number of recycled sheets S for the future period of the predetermined period "CY2023SC3" from the current month onwards. The server 60 can include the predicted recycled number of sheets S for the current month onwards in the graph information for the "monthly cumulative recycled sheet count SC1" as a "cumulative forecast line GC1." The server 60 can also predict and calculate a "cumulative target line GC2," which is the cumulative target number of sheets added with the "target number TC1," and include this in the graph information. The server 60 may use the "monthly average number UC1" to calculate the "current month's predicted number UC2," "current month's predicted environmental effect value UC3," "cumulative predicted line GC1," and "cumulative target line GC2."

[0069] The server 60 can transmit "third display information SSC" including this graph information to the terminal device 10. The terminal device 10 can display the received "third display information SSC" as a "third screen SC." 6, the "target number TC1," "target environmental effect value TC2," "environmental effect value TC3," and "number of recycled sheets TC4" are the same as those in FIG. 4, and therefore will not be described.

[0070] Next, Fig. 7 shows the "fourth screen SD" which is a screen displaying the "fourth display information SSD". The following mainly explains the differences with the "second screen SB" in Fig. 5 and the "third screen SC" in Fig. 6. The server 60 can predict and calculate the predicted number of sheets S to be recycled from the current month onwards based on the past "cumulative number of recycled sheets per month SD1," and can calculate the "predicted annual number UD4," which is the predicted number of sheets S to be recycled for the year.

[0071] In addition, the server 60 can predict and calculate the predicted environmental effect value of the sheets S from the current month onwards based on the past "cumulative number of recycled sheets per month SD1," and can predict and calculate the "predicted annual environmental effect value UD5," which is the predicted environmental effect value of the sheets S for the year. The server 60 may use the "monthly average number of sheets UD1" to calculate the "annual predicted number of sheets UD4" and the "annual predicted environmental effect value UD5." The server 60 can transmit the "fourth display information SSD" including the "annual predicted number UD4" and the "annual predicted environmental effect value UD5" to the terminal device 10, and the terminal device 10 can receive these and display them as the "fourth screen SD."

[0072] In addition, in Figure 7, "Model MD1", "Pull-down menu MD2" and "Pull-down menu MD3", "Sheet type TD5" and "Sheet type TD6", "Target number TD1", "Environmental effect value TD3", "Target environmental effect value TD2", and "Number of sheets recycled TD4" are the same as in Figure 5, so their explanation will be omitted. In addition, in Figure 7, "Cumulative SD2", "CY2023SD3", "Cumulative number of recycled sheets per month SD1", "Average number of sheets per month UD1", "Predicted number of sheets for this month UD2", "Predicted environmental effect value for this month UD3", and "Cumulative forecast line GD1" are the same as in Figure 6, so their explanation will be omitted.

[0073] As described above, the sheet recycling system 1 according to the embodiment includes a sheet recycling device 11 that recycles sheets S from waste paper M, a server 60 that receives sheet recycling information related to the recycling of sheets S from the sheet recycling device 11 and generates display information, and a terminal device 10 that receives and displays the display information from the server 60. The terminal device 10 transmits a target value for recycling the sheet S to the server 60 and requests display information. The server 60 converts the received target value into an environmental effect value, and transmits the environmental effect value to the terminal device 10 together with the display information.

[0074] In the above example, the server 60 converted the received target number of sheets S into the amount of CO2 reduction compared to a typical wet papermaking method. The server 60 also converted the target number of sheets S into the target amount of CO2 reduction. The server memory unit 60c of the server 60 can also store, for example, the respective coefficients related to the amount of wood and the amount of water used when recycling each specified sheet S, and the respective coefficients related to the amount of wood and the amount of water used when manufacturing one sheet of paper corresponding to the specified sheet S using a typical wet papermaking method.

[0075] The server 60 can read these coefficients from the server storage unit 60c and convert them in the same way as in the case of the CO2 reduction amount described above. That is, the server 60 can convert the received target number of sheets S into the amount of wood reduction and the amount of water reduction compared to a typical wet papermaking method. The server 60 can also convert the target number of sheets S from the target amount of wood reduction and the target amount of water reduction. The amount of wood reduction is also called the amount of forest resources saved, and the amount of water reduction is also called the amount of water consumption reduction. In this way, the environmental effect value that can be converted and displayed can include at least one of the amount of CO2 reduction, the amount of wood reduction, and the amount of water reduction. As a result, when the sheet recycling system 1 recycles waste paper M into sheets S, the user of the terminal device 10 can visually confirm the effect on the environment according to the target, which is highly convenient.

[0076] The above describes the embodiments in detail with reference to the drawings, but the specific configurations are not limited to these embodiments, and may be changed, replaced, deleted, etc., as long as they do not deviate from the gist of the present invention.

[0077] For example, when the sheet recycling device 11 recycles sheets S from waste paper M or the like, the server 60 may not need to use any wood. Also, the server 60 may use the amount of water consumed by the humidifying unit 83 of the sheet recycling device 11 to determine the amount of water used when recycling the sheets S. The amount of water consumed by the humidifying unit 83 is included in the sheet recycling information. The server 60 may also use the amount of water consumed by the humidifying unit 83 of the sheet recycling device 11 as the amount of water used when recycling the sheet S. The amount of water consumed by the humidifying unit 83 is included in the sheet recycling information. The server 60 may also calculate the amount of CO2 generated using the power consumption when the sheet S is recycled from waste paper M or the like in the sheet recycling device 11. This power consumption is included in the sheet recycling information.

[0078] In the above example, the sheet recycling device 11 calculates the number of sheets S to be recycled and the like from the weight of the sheets S detected by the sensor 87. The server 60 may receive information on the weight of the sheets S as sheet recycling information from the sheet recycling device 11, calculate the number of recycled sheets S instead of the sheet recycling device 11, and generate the above-mentioned display information.
