[0004] However, in such a recycled sheet production system, although the history is managed in the management server, the traceability of the produced sheets is low. As such, there is a demand for improving the convenience. [Means for solving the problem]

[0005] A recycled sheet production system that solves the above problems comprises a detection unit that detects the type of material contained in raw materials for manufacturing sheets; a defibrating unit that generates fibers by defibrating the raw materials for manufacturing sheets; a sheet manufacturing unit that manufactures sheets by depositing a mixture of fibers generated by the defibrating unit and a treatment agent; a printing unit that prints on sheets manufactured by the sheet manufacturing unit; a history acquisition unit that acquires, as history, sheet constituent components based on the type of material contained in the raw materials detected by the detection unit and the sheet manufacturing conditions for manufacturing sheets by the sheet manufacturing unit; and a registration unit that registers the sheet constituent components acquired by the history acquisition unit in association with the sheet manufacturing conditions, and the printing unit prints, in a designated area of ​​the sheet, an access address for accessing the sheet constituent components and the sheet manufacturing conditions registered by the registration unit.

[0006] A recycled sheet production method that solves the above problem involves one or more computers detecting the type of material contained in the raw materials used to produce the sheet, generating fibers by defibrating the raw materials used to produce the sheet, depositing a mixture of the generated fibers and a processing agent onto the fibers to produce a sheet, printing on the sheet, acquiring sheet constituent components based on the type of material contained in the raw materials and the manufacturing conditions for the produced sheet as a history, registering the sheet constituent components and the sheet manufacturing conditions in correspondence with each other, and printing an access address for accessing the sheet constituent components and the sheet manufacturing conditions in a specified area of ​​the sheet.

[0007] A program for solving the above problem causes one or more computers to detect the type of material contained in raw materials for manufacturing a sheet, generate fibers by defibrating the raw materials for manufacturing the sheet, manufacture a sheet by depositing a mixture of the generated fibers and a treatment agent, print on the sheet, obtain sheet constituent components based on the type of material contained in the raw materials and the manufacturing conditions of the manufactured sheet as a history, register the sheet constituent components and the sheet manufacturing conditions in correspondence with each other, and print an access destination for accessing the sheet constituent components and the sheet manufacturing conditions in a specified area of ​​the sheet.

[0051] <Data Structure of Setting Storage Unit 21A> 1 and 2, the management storage unit 21 includes a setting storage unit 21A. The setting storage unit 21A stores a recommended setting database. The recommended setting database is a database that stores the correspondence between recommended settings and each setting item. The setting items may include sheet constituent components, sheet manufacturing conditions, printing conditions, drying conditions, and post-processing conditions.

[0052] In this way, the setting memory unit 21A stores the correspondence between the recommended components of the sheet constituents, the recommended settings of the sheet manufacturing conditions, the recommended settings of the printing conditions, the recommended settings of the drying conditions, and the recommended settings of the post-processing conditions.

[0053] The recommended settings are estimated by referencing the recommended settings database. More specifically, when the user specifies the settings of sheet constituent components and printing conditions, the recommended settings of sheet manufacturing conditions, the recommended settings of drying conditions, and the recommended settings of post-processing conditions are estimated based on the settings of sheet constituent components and printing conditions. When the user specifies the settings of sheet constituent components and sheet manufacturing conditions, the recommended settings of printing conditions, the recommended settings of drying conditions, and the recommended settings of post-processing conditions are estimated based on the settings of sheet constituent components and sheet manufacturing conditions.

[0054] As a specific example of the recommended settings database, the number of layers of a sheet, the thickness of a sheet, and the unevenness of a sheet may be associated with the position of a liquid ejection head as a printing condition, thereby enabling printing under the recommended printing conditions for the sheet to be manufactured.

[0055] The sheet manufacturing conditions, such as the base color of the sheet, the heating temperature of the sheet, and the weight of the material of the sheet, may be associated with the printing conditions, such as the color correction and the liquid ejection amount, thereby enabling printing under the recommended printing conditions for the sheet to be manufactured.

[0056] The positions of the seams in the nonwoven fabric sheet and the holes in the sheet may be associated with the printing range as a printing condition, thereby enabling control so that printing is performed in an appropriate printing range.

[0057] The amount of sheet elongation as a sheet manufacturing condition may be associated with sheet elongation correction as a printing condition, thereby enabling printing to be performed under printing conditions recommended for the amount of sheet elongation.

[0058] The raw materials as the sheet constituent components may be associated with the liquid ejection amount as the printing condition, thereby enabling printing under printing conditions suitable for the raw materials as the sheet constituent components.

[0059] The moisture content of the dough of the sheet as the sheet production condition may be associated with the drying time and drying temperature as the drying conditions, thereby allowing the sheet to be dried under the drying conditions recommended for the sheet to be produced.

[0060] The sheet manufacturing conditions, such as the sheet thickness, the sheet elongation amount, and the type of material on the outermost surface of the sheet, may be associated with the tumble processing time as a post-processing condition, thereby enabling the sheet to be post-processed under the post-processing conditions recommended for the sheet being manufactured.

[0061] The type of material of the outermost surface of the sheet may be associated with the post-processing conditions of the coating process as the sheet manufacturing conditions, thereby enabling post-processing of the sheet to be performed under the post-processing conditions recommended for the manufactured sheet.

[0062] <Data Structure of History Storage Unit 21B> 1 and 3, the management storage unit 21 includes a history storage unit 21B. A history database is stored in the history storage unit 21B. The history database is a database for managing the manufacturing history.

[0063] The manufacturing history database associates a management ID, a user ID, an access destination, a password, and a manufacturing history. The management ID is information for managing the manufacturing history. The user ID is identification information for the user who manufactures the sheet. The access destination and password are information for accessing the manufacturing history corresponding to the management ID.

[0064] In this way, when production including sheet production, printing on the sheet, drying of the sheet, and post-processing of the sheet is performed, the production history corresponding to the management ID is stored in a cumulative manner in the history storage unit 21B. When authentication is successfully performed using the access destination and password, the production history stored in the history storage unit 21B can be accessed.

[0065] <Access destination image 93 and password image 94> As shown in FIG. 4, recycled cloth 90, which is an example of a sheet, has a first region 91 and a second region 92. The recycled cloth 90 is transported in a conveying direction D, which intersects with the width direction X of the recycled cloth 90. The first region 91 is a region located at the center of the recycled cloth 90 in the width direction X. The second region 92 is a region located on the end 90A side of the recycled cloth 90 in the width direction X. The second region 92 is a region of the recycled cloth 90 that is difficult to use as fabric.

[0066] An image specified by the user is printed in the first area 91 by the printing device 14. An image specified by the user is not printed in the second area 92 by the printing device 14. In addition to the image specified by the user, an access destination image 93 and a password image 94 are printed in the second area 92 by the printing device 14. The area where the access destination image 93 and the password image 94 are printed corresponds to an example of a predetermined area.

[0067] The access destination image 93 is an image that indicates the access destination to the manufacturing history of the recycled cloth 90. The access destination image 93 may be a two-dimensional code. The access destination image 93 may include an image that indicates an administration ID corresponding to the manufacturing history of the recycled cloth 90. The password image 94 is an image that indicates a password that enables access to the manufacturing history of the recycled cloth 90.

[0068] The access destination image 93 and the password image 94 are printed at an interval of distance d1 in the transport direction D. That is, the printing unit 46 prints the access destination and the password at a predetermined interval indicated by the distance d1 in the transport direction D.

[0069] <Various processing> Various processes will now be described. The processes executed by the control device 11 and the management server 12 will be described below. In particular, the processes will be described focusing on the printing device 14 as a representative of the control device 11, and the processes executed by the sheet manufacturing device 13, the drying device 15, and the post-processing device 16 will be described focusing on the differences.

[0070] <Settings control process> The setting control process will be described with reference to Fig. 5. The setting control process is a process that is executed by the control device 11 and the management server 12 at predetermined intervals.

[0071] As shown in FIG. 5, in step S10, the printing control unit 40 of the printing device 14 determines whether a recommendation request has been issued. A recommendation request is a request issued by a user. The recommendation request may be input from the printing input unit 43. A recommendation request is a request for recommended settings to the management server 12.

[0072] If the print control unit 40 determines that a recommendation request has not been issued, the process proceeds to step S13. If the print control unit 40 determines that a recommendation request has been issued, the process proceeds to step S11.

[0073] In step S11, the print control unit 40 executes a request target determination process. In this process, the print control unit 40 may determine a target for which recommended settings are requested in response to a user instruction. The print control unit 40 may determine one or more targets for which recommended settings are requested in response to a user instruction.

[0074] As a specific example, the print control unit 40 may determine sheet production conditions as the target for the recommended settings request in response to a user instruction. The print control unit 40 may determine printing conditions as the target for the recommended settings request in response to a user instruction. The print control unit 40 may determine sheet production conditions, drying conditions, and post-processing conditions as the target for the recommended settings request in response to a user instruction. The print control unit 40 may determine printing conditions, drying conditions, and post-processing conditions as the target for the recommended settings request in response to a user instruction.

[0075] In step S12, the print control unit 40 executes a recommendation request transmission process. The print control unit 40 transmits a recommendation request to the management server 12. The recommendation request may include various settings and conditions determined as targets for the request for recommended settings.

[0076] As a specific example, when the print control unit 40 determines that the sheet manufacturing conditions are the target of the recommended settings request, it acquires the sheet constituent components, printing condition settings, drying condition settings, and post-processing condition settings, excluding the sheet manufacturing conditions. The print control unit 40 may acquire the sheet constituent components, drying condition settings, and post-processing condition settings through communication with the sheet manufacturing apparatus 13, the drying apparatus 15, and the post-processing apparatus 16. The print control unit 40 generates a recommendation request that includes the acquired sheet constituent components, printing condition settings, drying condition settings, and post-processing condition settings, as well as information that the sheet manufacturing conditions are the target of the recommended settings request.

[0077] When the print control unit 40 determines that the printing conditions are the target of the recommended settings request, it acquires the sheet constituent components, sheet manufacturing condition settings, drying condition settings, and post-processing condition settings, excluding the printing conditions. The print control unit 40 may acquire the sheet constituent components, sheet manufacturing condition settings, drying condition settings, and post-processing condition settings through communication with the sheet manufacturing apparatus 13, the drying apparatus 15, and the post-processing apparatus 16. The print control unit 40 generates a recommendation request that includes the acquired sheet constituent components, sheet manufacturing condition settings, drying condition settings, and post-processing condition settings, as well as information that the printing conditions are the target of the recommended settings request.

[0079] When the print control unit 40 determines that the post-processing conditions are the target of the recommended settings request, it acquires the sheet constituent components, the sheet manufacturing condition settings, the printing condition settings, and the drying condition settings, excluding the post-processing conditions. The print control unit 40 may acquire the sheet constituent components, the sheet manufacturing condition settings, and the drying condition settings through communication with the sheet manufacturing apparatus 13 and the drying apparatus 15. The print control unit 40 generates a recommendation request that includes the acquired sheet constituent components, the sheet manufacturing condition settings, the printing condition settings, and the drying condition settings, and a statement that the post-processing conditions are the target of the recommended settings request.

[0080] In the management server 12, in step S50, the management control unit 20 determines whether a recommendation request has been received from the printing device 14. If the management control unit 20 determines that a recommendation request has not been received from the printing device 14, it terminates the setting control process. If the management control unit 20 determines that a recommendation request has been received from the printing device 14, it proceeds to step S51.

[0081] In step S51, the management control unit 20 executes a recommended request acquisition process. In this process, the management control unit 20 receives the sheet constituent components and various condition settings included in the recommended request from the printing device 14, and thereby acquires the sheet constituent components and various condition settings.

[0082] In detail, the management control unit 20 acquires the sheet constituent components when the sheet constituent components detected by the sheet manufacturing apparatus 13 are included in the recommendation request. The management control unit 20 acquires the settings of the sheet manufacturing conditions when the recommendation request includes the settings of the sheet manufacturing conditions for the sheet manufactured by the sheet manufacturing apparatus 13. The management control unit 20 acquires the settings of the printing conditions when the recommendation request includes the settings of the printing conditions for printing on the sheet by the printing device 14. The management control unit 20 acquires the settings of the drying conditions when the recommendation request includes the settings of the drying conditions for drying the sheet by the drying device 15. The management control unit 20 acquires the settings of the post-processing conditions when the recommendation request includes the settings of the post-processing conditions for post-processing the sheet by the post-processing device 16.

[0083] In step S52, the management control unit 20 executes a recommended setting determination process. In this process, the management control unit 20 determines recommended settings corresponding to the requested setting items based on the settings included in the recommendation request. In particular, the management control unit 20 determines recommended settings by referencing the recommended setting database and reading out recommended settings corresponding to the settings included in the recommendation request for each requested setting item.

[0084] In this way, the management control unit 20 determines the recommended settings based on the recommended settings database and the settings received from the printing device 14. In other words, the management control unit 20 determines the recommended settings based on the correspondence between various conditions and the settings received from the printing device 14.

[0085] The management control unit 20 determines recommended settings for sheet manufacturing conditions based on at least one of the sheet constituent components, printing condition settings, drying condition settings, and post-processing condition settings. The management control unit 20 determines recommended settings for printing conditions based on at least one of the sheet constituent components, sheet manufacturing condition settings, drying condition settings, and post-processing condition settings. The management control unit 20 determines recommended settings for drying conditions based on at least one of the sheet constituent components, sheet manufacturing condition settings, printing condition settings, and post-processing condition settings. The management control unit 20 determines recommended settings for post-processing conditions based on at least one of the sheet constituent components, sheet manufacturing condition settings, printing condition settings, and drying condition settings.

[0086] As a specific example, the management control unit 20 refers to the recommended settings database and determines recommended settings corresponding to the settings of sheet constituent components and printing conditions as recommended settings for sheet manufacturing conditions, recommended settings for drying conditions, and recommended settings for post-processing conditions. The management control unit 20 refers to the recommended settings database and determines recommended settings corresponding to the settings of sheet constituent components and sheet manufacturing conditions as recommended settings for printing conditions, recommended settings for drying conditions, and recommended settings for post-processing conditions.

[0087] In step S53, the management control unit 20 executes a recommended settings transmission process. In this process, the management control unit 20 transmits recommended settings to the printing device 14 that sent the recommendation request. As a result, the management control unit 20 provides various recommended settings to the control device 11.

[0088] In the printing device 14, in step S13, the print control unit 40 determines whether or not recommended settings have been received from the management server 12. If the print control unit 40 determines that recommended settings have not been received from the management server 12, it ends the setting control process. If the print control unit 40 determines that recommended settings have been received from the management server 12, it proceeds to step S14.

[0089] In step S14, the print control unit 40 determines whether or not the user has issued a permission instruction. If the print control unit 40 determines that the user has not issued a permission instruction, it ends the setting control process. If the print control unit 40 determines that the user has issued a permission instruction, it proceeds to step S15.

[0090] In step S15, the print control unit 40 executes a recommended setting process. In this process, the print control unit 40 controls to set the received recommended settings. Specifically, when the print control unit 40 receives the recommended settings for the sheet manufacturing conditions, the print control unit 40 controls to set the recommended settings for the sheet manufacturing conditions through communication with the sheet manufacturing apparatus 13. As a result, the sheet manufacturing unit 37 manufactures sheets based on the recommended settings for the sheet manufacturing conditions in response to instructions from the user.

[0091] When the print control unit 40 receives the recommended settings of the printing conditions, it controls the print unit 46 to set the recommended settings of the printing conditions, so that the print unit 46 prints an image on a sheet based on the recommended settings of the printing conditions in response to an instruction from the user.

[0092] When the print control unit 40 receives the recommended settings for the drying conditions, it controls the drying unit 55 to set the recommended settings for the drying conditions through communication with the drying device 15. As a result, the drying unit 55 dries the sheet based on the recommended settings for the drying conditions in response to an instruction from the user.

[0093] When the print control unit 40 receives the recommended settings of the post-processing conditions, it controls the post-processing unit 16 to set the recommended settings of the post-processing conditions through communication with the post-processing unit 16. As a result, the post-processing unit 65 performs post-processing of the sheet based on the recommended settings of the post-processing conditions in response to instructions from the user.

[0094] In this way, when the conditions for providing recommended settings are met, the management control unit 20 provides the recommended settings to the control device 11. The conditions for providing recommended settings are met when a recommendation request is received from the printing device 14.

[0095] In detail, when the conditions for providing recommended settings are met, the management control unit 20 provides the sheet manufacturing device 13 with recommended settings for the sheet manufacturing conditions. When the conditions for providing recommended settings are met, the management control unit 20 provides the printing device 14 with recommended settings for the printing conditions.

[0096] <History control processing> The history control process will be described with reference to Fig. 6. The history control process is a process that is executed by the control device 11 and the management server 12 at predetermined intervals.

[0097] As shown in FIG. 6, in the printing device 14, in step S20, the print control unit 40 determines whether the history transmission condition is met. The history transmission condition may be met for each sheet production lot, or for each sheet to be produced. The history transmission condition may be met before the start of production of the sheet production lot, during production, or after production is completed. In other words, the history transmission condition may be met before the start of sheet production, during production, or after production is completed. The history transmission condition may be met before printing on the sheet starts, during production, or after production is completed. The history transmission condition may be met before drying of the sheet starts, during production, or after production is completed. The history transmission condition may be met before post-processing of the sheet starts, during production, or after production is completed.

[0098] If the print control unit 40 determines that the history transmission condition is not met, it ends the history control process. If the print control unit 40 determines that the history transmission condition is met, it proceeds to step S21.

[0099] In step S21, the print control unit 40 executes a history transmission process. In this process, the print control unit 40 acquires the manufacturing history. Specifically, the print control unit 40 acquires the sheet constituent components detected by the detection unit 35 as the manufacturing history through communication with the sheet manufacturing apparatus 13. The print control unit 40 acquires the sheet manufacturing conditions as the manufacturing history through communication with the sheet manufacturing apparatus 13. The print control unit 40 acquires the printing conditions as the manufacturing history from the print storage unit 41. The print control unit 40 acquires the drying conditions as the manufacturing history through communication with the drying device 15. The print control unit 40 acquires the post-processing conditions as the manufacturing history through communication with the post-processing device 16. The print control unit 40 transmits the acquired manufacturing history to the management server 12.

[0100] In the management server 12, in step S60, the management control unit 20 determines whether or not the manufacturing history has been received from the printing device 14. If the management control unit 20 determines that the manufacturing history has not been received from the printing device 14, it terminates the history control process. If the management control unit 20 determines that the manufacturing history has been received from the printing device 14, it proceeds to step S61.

[0101] In step S61, the management control unit 20 executes a history acquisition process. In this process, the management control unit 20 receives the manufacturing history from the printing device 14, thereby acquiring the manufacturing history.

[0102] Specifically, the management control unit 20 acquires, as the manufacturing history, the sheet constituent components detected in the sheet manufacturing apparatus 13 and the manufacturing conditions of the sheet manufactured by the sheet manufacturing apparatus 13. The management control unit 20 acquires, as the manufacturing history, the printing conditions under which the sheet is printed by the printing device 14. The management control unit 20 acquires, as the manufacturing history, the drying conditions under which the sheet is dried by the drying device 15. The management control unit 20 acquires, as the manufacturing history, the post-processing conditions under which the sheet is post-processed by the post-processing device 16.

[0103] In step S62, the management control unit 20 executes a history registration process. In this process, the management control unit 20 acquires from the management storage unit 21 the user ID of the user who uses the printing device 14 that transmitted the manufacturing history. The management control unit 20 generates a management ID, an access destination, and a password. The management control unit 20 associates the management ID, user ID, access destination, password, and manufacturing history and registers them in the history storage unit 21B.

[0104] In this way, the management control unit 20 associates the management ID, sheet constituent components, sheet manufacturing conditions, printing conditions, drying conditions, and post-processing conditions, and registers them as manufacturing history. The management control unit 20 also associates the management ID, access destination, and password, and registers them. As a result, the management control unit 20 associates the manufacturing history, access destination, and password, and registers them.

[0105] In step S63, the management control unit 20 executes an access destination transmission process. In this process, the management control unit 20 transmits the access destination and password associated with the manufacturing history to the printing device 14. As a result, when the conditions for providing the access destination are met, the management control unit 20 provides the access destination and password to the printing device 14.

[0106] In the printing device 14, the print control unit 40 receives the access destination and the password. When printing an image on a sheet, the print control unit 40 prints an access destination image 93 and a password image 94 in a predetermined area on the sheet based on the access destination and the password.

[0107] In this way, the printing unit 46 prints the access destination and password for accessing the manufacturing history in a predetermined area on the sheet. In particular, the printing unit 46 prints the access destination and password in a predetermined area on the sheet at predetermined intervals in the conveyance direction D.

[0108] <History provision process> The history providing process will be described with reference to Fig. 7. The history providing process is a process that is executed by the terminal device and the management server 12 at predetermined intervals.

[0109] 7, in the terminal device, in step S30, the terminal control unit determines whether the history request transmission condition is met. The history request transmission condition may be met in response to a user instruction. In particular, the terminal control unit may determine that the history request transmission condition is met by capturing an access destination image 93 printed on a sheet and entering a password in response to a user instruction.

[0110] If the terminal control unit determines that the history request transmission condition is not met, the process proceeds to step S32. If the terminal control unit determines that the history request transmission condition is met, the process proceeds to step S31.

[0111] In step S31, the terminal control unit executes a history request transmission process. In this process, the terminal control unit transmits a history request to the management server 12. The history request includes an access destination and a password input in response to a user instruction. The history request may also include information for communicating with the terminal device.

[0112] In the management server 12, in step S70, the management control unit 20 determines whether or not a history request has been received from the terminal device. If the management control unit 20 determines that a history request has not been received from the terminal device, it terminates the history providing process. If the management control unit 20 determines that a history request has been received from the terminal device, it proceeds to step S71.

[0113] In step S71, the management control unit 20 determines whether authentication has been successful based on the received access destination and password. If the management control unit 20 determines that authentication has not been successful, it ends the history providing process. If the management control unit 20 determines that authentication has been successful, it proceeds to step S72.

[0114] In step S72, the management control unit 20 executes a history provision control process. In this process, the management control unit 20 transmits the manufacturing history corresponding to the access destination and password to the terminal device. This allows the management control unit 20 to provide the manufacturing history to the terminal device.

[0115] In the terminal device, in step S32, the terminal control unit determines whether or not the manufacturing history has been received from the management server 12. If the terminal control unit determines that the manufacturing history has not been received from the management server 12, it terminates the history providing process. If the terminal control unit determines that the manufacturing history has been received from the management server 12, it proceeds to step S33.

[0116] In step S33, the terminal control unit executes a history display process. In this process, the terminal control unit displays the manufacturing history on the terminal display unit. This allows the manufacturing history to be confirmed by accessing the access destination printed in a predetermined area on the sheet.
