The computer program may be distributed to the computer system 1000 via a network.

[0025] Similarly, each of the sewing machine controller 8 and the information terminal 11 includes a computer system having a processor, a main memory, a storage, and an interface.

[0026] [Management device, sewing machine and information terminal] FIG. 3 is a functional block diagram showing the management device 3, the sewing machine 2, and the information terminal 11 according to the embodiment. As shown in FIG. 3, the information terminal 11 includes a terminal controller 12, a display device 13 such as a flat panel display, an input device 14 such as a touch panel, and an identification device 15. The input device 14 generates input data by being operated by an inspector. The input device 14 may be operated by an operator or a manager. The terminal controller 12 transmits the input data generated by the operation of the input device 14 to the management controller 6. The identification device 15 outputs identification data indicating the identification result of the identification tag 101 by the identification device 15. The terminal controller 12 transmits identification data indicating the identification result of the identification tag 101 by the identification device 15 to the management controller 6. The display device 13 displays guidance data indicating the inspection items and inspection method of the sewing object 100 transmitted from the management controller 6.

[0027] The management controller 6 includes a correlation data storage unit 61 and an output unit 62 .

[0028] The correlation data storage unit 61 stores correlation data indicating a relationship between a plurality of sewing processes for sewing the sewing object 100 using the sewing machine 2 and an inspection level for an inspection process of the sewing object 100 performed after the sewing process. The correlation data is determined in advance. The correlation data is input to the management controller 6 from, for example, the input device 5. For example, an administrator operates the input device 5 to store the correlation data in the correlation data storage unit 61.

[0029] In the embodiment, the correlation data indicates the relationship between the sewing process, the inspection process, the sewing object 100, and the inspection level. As described with reference to FIG. 1, in the embodiment, the sewing process includes a first process, a second process, and a third process. The inspection process includes an intermediate inspection and a final inspection. The intermediate inspection may include, for example, a first intermediate inspection for inspecting the sewing object 100 after the first process, and a second intermediate inspection for inspecting the sewing object 100 after the second process. The sewing object 100 includes a first sewing object 100A and a second sewing object 100B.

[0030] In the embodiment, the inspection level refers to the tolerance for the target value (target state) of the sewing object 100. When the tolerance is small, the inspection level is high (strict). When the tolerance is large, the inspection level is low (loose). For example, when a target position of a stitch is set, the inspection level is the tolerance for the amount of deviation of the stitch from the target position. When the inspection level is high, the tolerance for the amount of deviation is small. When the inspection level is low, the tolerance for the amount of deviation is large. As an example, when the inspection level is high, the tolerance for the amount of deviation is 0.5 mm. When the inspection level is high, if the amount of deviation exceeds 0.5 mm, the sewing object 100 is determined to be defective. When the inspection level is low, the tolerance for the amount of deviation is 2.0 mm. When the inspection level is low, if the amount of deviation exceeds 0.5 mm but is equal to or less than 2.0 mm, the sewing object 100 is determined to be good. When the amount of deviation exceeds 2.0 mm, the sewing object 100 is determined to be defective.

[0031] The output unit 62 causes the display device 13 of the information terminal 11 to display an inspection level suited to the inspection process. The display device 13 is an example of an output device that outputs an inspection level suited to the inspection process. As described above, an identification tag 101 for identifying the sewing object 100 is attached to the sewing object 100. The output unit 62 causes the display device 13 to display the inspection level based on the identification data of the identification tag 101 by the identification device 15 and the correlation data stored in the correlation data storage unit 61.

[0032] [Correlation Data] FIG. 4 is a diagram showing an example of correlation data according to an embodiment. As shown in FIG. 4, in the embodiment, the correlation data shows the relationship between the sewing object 100, the inspection process performed after the sewing process, the inspection item in the inspection process, and the inspection level. The sewing object 100 includes a first sewing object 100A for manufacturing a T-shirt and a second sewing object 100B for manufacturing a Y-shirt. The inspection process includes a first intermediate inspection performed after the first process, a second intermediate inspection performed after the second process, and a final inspection performed after the third process. The inspection items include item A, item B, and item C. As an example, item A is the amount of deviation of the stitch from the target position. Item B is the amount of fraying of the thread. Item C is the amount of deviation of the overlapping fabrics. The inspection levels are level 1, which is the lowest, level 2, which is the next lowest, and level 3, which is the highest.

[0033] For example, the inspection level of the final inspection is high. For example, if the first or second sewing process is a process for manufacturing a lining, the inspection level of the first intermediate inspection or the second intermediate inspection may be low since the lining is a part that is not visible after the sewn product is completed. The manager sets the inspection level according to the inspection process carried out after the sewing process. The manager creates correlation data as shown in FIG. 4, which indicates the relationship between the sewing object 100, the inspection process carried out after the sewing process, the inspection items in the inspection process, and the inspection level. The manager operates the input device 5 to store the created correlation data in the correlation data storage unit 61.

[0034] [Sewing management method] 5 is a flowchart showing a sewing management method according to an embodiment. Hereinafter, as an example, a sewing management method when the first sewing object 100A is subjected to a first intermediate inspection will be described. An inspector who performs the first intermediate inspection carries a first information terminal 11A.

[0035] The first sewing object 100A that has completed the first process is sent to the first intermediate inspection. An inspector reads the first identification tag 101A attached to the first sewing object 100A with the identification device 15 of the first information terminal 11A. The terminal controller 12 transmits identification data indicating the identification result of the first identification tag 101A by the identification device 15 to the management controller 6. In the embodiment, an identifier (ID) is attached to each of the multiple information terminals 11. The terminal controller 12 transmits the ID data of the first information terminal 11A to the management controller 6. The management controller 6 acquires the identification data of the first identification tag 101A and the ID data of the first information terminal 11A transmitted from the first information terminal 11A (step S1).

[0036] The first information terminal 11A is the information terminal 11 used for the first intermediate inspection. It is predetermined that the first information terminal 11A will be used for the first intermediate inspection. The management controller 6 can recognize that the first sewing object 100A will be subjected to the first intermediate inspection by acquiring the ID data of the first information terminal 11A. That is, the management controller 6 can recognize that the inspection process of the first sewing object 100A is the first intermediate inspection by acquiring the ID data of the first information terminal 11A.

[0037] The output unit 62 transmits an inspection level suited to the inspection process of the first sewing object 100A to the first information terminal 11A based on the identification data of the identification tag by the identification device 15 and the correlation data stored in the correlation data storage unit 61 (step S2). The terminal controller 12 of the first information terminal 11A causes the display device 13 to display the correlation data corresponding to the first sewing object 100A and the first intermediate inspection transmitted from the management controller 6.

[0038] FIG. 6 is a diagram showing an example of correlation data displayed on the display device 13 of the first information terminal 11A according to the embodiment. As shown in FIG. 6, the display device 13 displays correlation data corresponding to the first sewing object 100A and the first intermediate inspection among the correlation data shown in FIG. 4. The inspector inspects the first sewing object 100A while checking the correlation data displayed on the display device 13. In the first intermediate inspection, the inspector inspects the first sewing object 100A for the inspection items A, B, and C. The inspection level of the A item is level 2, the inspection level of the B item is level 1, and the inspection level of the C item is level 1. The inspector inspects the first sewing object 100A for each of the A item, B item, and C item according to the specified inspection level.

[0039] The sewing management method when the first sewing object 100A is subjected to the first intermediate inspection has been described above. The same applies when the first sewing object 100A is subjected to the second intermediate inspection and final inspection, and the same applies when the second sewing object 100B is subjected to the first intermediate inspection, the second intermediate inspection, and the final inspection.

[0040] [effect] As described above, in the embodiment, the sewing management system 1 includes a correlation data storage unit 61 that stores correlation data indicating the relationship between a plurality of sewing processes for sewing the sewing object 100 using the sewing machine 2 and an inspection level for an inspection process of the sewing object performed after the sewing process, and an output unit 62 that outputs the inspection level corresponding to the inspection process to the display device 13, which is an output device.

[0041] According to the embodiment, the sewing object 100 is properly inspected in each of the multiple inspection processes. If the inspection level of each of the multiple inspection processes is uniformly high, the productivity of the sewn product will decrease if the inspection process or inspection item, which may be inspected at a low inspection level, is inspected strictly. If the inspection level of each of the multiple inspection processes is uniformly low, the inspection process or inspection item, which requires a high inspection level, is inspected laxly, resulting in the production of a defective sewn product. By determining the inspection level according to each of the multiple inspection processes and inspection items, proper inspection is performed. In addition, the inspection level is displayed on the display device 13 as guidance data, so that variation in the inspection level depending on the inspector is suppressed.

[0042] In the embodiment, the correlation data indicates the relationship between the inspection process, the sewing object 100, and the inspection level. This allows an appropriate inspection to be performed according to the sewing object 100. Also, in the embodiment, the correlation data indicates the relationship between the inspection process, the inspection item in the inspection process, the sewing object 100, and the inspection level. This allows an appropriate inspection to be performed according to the inspection item.

[0043] An identification tag 101 for identifying the sewing object 100 is attached to the sewing object 100. The output unit 62 outputs an inspection level based on the correlation data and the identification data of the identification tag 101 by the identification device 15. As a result, the correlation data matched to the sewing object 100 is displayed on the display device 13. [Explanation of symbols]
