[0033] In addition, in the execution areas of various processes included in the sewing production line SL, an operator OP who executes the corresponding operation process is arranged. The operator OP has a terminal 10 configured to be attachable and detachable to the body. The terminal 10 constitutes an example of a terminal that detects the physical condition management information of the operator OP who works in the sewing production line SL. For example, the terminal 10 is constituted by a wearable terminal, but is not limited thereto. Hereinafter, the terminal 10 will be described as the wearable terminal 10. In Figure 1 it shows a case where only the operator OP in the sewing process 4 is loaded with the wearable terminal 10, but the wearable terminal 10 can also be loaded on the operator OP arranged in various processes other than the sewing process 4.

[0034] The wearable terminal 10 is loaded on the wrist or the like of the operator OP and is configured to be able to detect the biological information of the operator OP.

For example, the display unit 43 displays an operation screen for operating the portable terminal 40, a product number ID read by the identification information reader unit 46 described later, an operator ID, etc. The input unit 44 receives inputs such as operation instructions from the operator. For example, the input unit 44 receives from the operator an instruction to read the operator ID and the product number ID. In addition, Figure 3 in this case, the display unit 43 and the input unit 44 are configured to be independent of each other, but this is not limited thereto. For example, it may also be a structure that combines the functions of the display unit 43 and the input unit 44 through a touch panel or the like.

[0044] The I / F unit 45 constitutes an interface between an external terminal and the control unit 41. A sewing machine 9 is connected to the I / F unit 45. Information between the cutting machine and the portable terminal 40 is exchanged via the I / F unit 45. For example, the operation information in the drive unit 97 of the sewing machine 9 and the production data in the sewing machine 9 are output to the portable terminal 40. The identification information reader unit 46 reads, in a non-contact manner, the operator ID in the ID card carried by the operator, the product number ID in the RFID tag attached to the fabric, etc. The communication unit 47 communicates with the management server 8, etc. via the network NW2 of the sewing management system 1. For example, the communication unit 47 sends the operator ID, product number ID read via the identification information reader unit 46, and the operation information of the sewing machine 9 received via the I / F unit 45, etc. to the management server 8.

[0045] Having the above-described structure, the portable terminal 40 receives the operation information of the sewing machine 9 via the I / F unit 45. In addition, the portable terminal 40 reads, in response to an instruction from the input unit 44, the operator ID in the ID card carried by the operator, the product number ID in the RFID tag attached to the fabric, etc. These cutting piece numbers, operator ID, and product number ID are output to the management server 8 via the communication unit 47.

[0046] The portable terminals 30, 50, 60, and 70 for the cutting process 3, the finishing process 5, the inspection process 6, and the packaging process 7 are connected via the I / F unit to different objects and communicate different information with the connected objects.

For example, the display unit 13 displays an operation screen for operating the wearable terminal 10, the operator ID read by the identification information reader unit 15 described later, and the like. The input unit 44 receives inputs such as operation instructions from the operator OP. For example, the input unit 14 receives an instruction to read the operator ID from the operator OP. In addition, in Figure 4 , the display unit 13 and the input unit 14 are provided as independent structures, but it is not limited thereto. For example, it may be a structure that combines the functions of the display unit 13 and the input unit 14 through a touch panel or the like.

[0049] The identification information reader unit 15 reads the operator ID and the like in the ID card carried by the operator OP in a non-contact manner. The sensor unit 16 detects the biological information and activity amount information of the operator OP on which it is mounted. Here, it is assumed that the sensor unit 16 detects the body temperature, heart rate, and blood pressure of the operator OP as biological information, and can also detect the number of steps of the operator OP as activity amount information. The communication unit 17 communicates with the management server 8 and the like via the network NW2 of the sewing management system 1. For example, the communication unit 17 sends the operator ID read by the identification information reader unit 15, the biological information and activity amount information of the operator OP detected by the sensor unit 16 to the management server 8.

[0050] Having the structure described above, the wearable terminal 10 reads the operator ID in the ID card carried by the operator through the identification information reader unit 15 in response to an instruction from the input unit 14. In addition, the wearable terminal 10 detects the biological information and activity amount information of the operator OP through the sensor unit 16 in response to an instruction from the input unit 14 or at a predetermined time. These operator ID, biological information, etc. are output to the management server 8 via the communication unit 17.

[0051] The management server 8 manages the information output from the devices in various processes. These information are used as information for managing the production in the sewing production line SL. Hereinafter, for the sake of convenience of explanation, these information are referred to as "production management information". The management server 8 manages these production management information in units of products sewn through the sewing production line SL or in units of components constituting the products. In addition, the management server 8 manages the information output from the wearable terminal 10. These information are used as information for managing the physical condition of the operator (physical condition management information). The management server 8 manages the physical condition management information for each operator. Moreover, the management server 8 estimates the sewing skills of the operator based on the production management information, and estimates the production capacity of the operator based on the physical condition management information. And the management server 8 analyzes the sewing quality and production efficiency in the sewing production line SL in accordance with these estimation results. In addition, the production management information and physical condition management information managed by the management server 8 are described later.

[0052] Figure 5 is a block diagram showing the structure of the management server 8 constituting the sewing management system 1 according to the present embodiment. As Figure 5 shown, the management server 8 includes: a control unit 81 that controls the entire server; and a storage unit 82, a display unit 83, an input unit 84, a communication unit 85, a form management unit 86, and a form storage unit 87, which are connected to the control unit 81.

The storage unit 82 stores the programs executed by the control unit 81 and serves as a working area for the control unit 81.

[0053] The display unit 83 displays the information required for the operation of the management server 8. For example, the display unit 83 displays an operation screen for operating the management server 8, an analysis result screen, etc., and the analysis result screen is used to display the analysis result of the sewing production line SL based on the production management information. The input unit 84 receives inputs such as operation instructions from the manager of the management server 8. For example, the input unit 84 receives an analysis instruction for the sewing production line SL from the manager. In addition, in Figure 5In this case, the display unit 83 and the input unit 84 are configured to be independent of each other, but are not limited thereto. For example, the functions of the display unit 83 and the input unit 84 may also be combined by a touch panel or the like.

[0054] The communication unit 85 communicates with the devices of various processes of the sewing production line SL via the network NW2 of the sewing management system 1. For example, the communication unit 85 receives production management information including the operator ID and the operation information in the drive unit 97 from the portable terminal 40 of the sewing process 4. In addition, the communication unit 85 communicates with the wearable terminals 10 of various processes of the sewing production line SL via the network NW2 of the sewing management system 1. For example, the communication unit 85 receives physical condition management information including the operator ID and the biological information from the wearable terminal 10 of the sewing process 4.

[0055] The form management unit 86 generates a production management information form based on the production management information received by the communication unit 85, and manages the production management information. In addition, the form management unit 86 generates a physical condition management information form based on the physical condition management information received by the communication unit 85, and manages the production management information. The form storage unit 87 stores the production management information form and the physical condition management information form generated by the form management unit 86. The form storage unit 87 stores the sewing skill form described later.

[0056] Here, refer to Figure 6 and Figure 7 An example of the production management information form and the physical condition management information form stored in the form storage unit 87 will be described. Figure 6 FIG. is an explanatory diagram of an example of the production management information form 600 stored in the form storage unit 87 of the management server 8 according to the present embodiment. Figure 7 FIG. is an explanatory diagram of an example of the physical condition management information form 700 stored in the form storage unit 87 of the management server 8 according to the present embodiment. In addition, regarding the registration contents of the production management information form 600 and the physical condition management information form 700 stored in the form storage unit 87, they are not limited to Figure 6 , Figure 7 the contents shown, and can be appropriately changed.

[0057] In Figure 6In the production management information table 600 shown, production management information related to product numbers ID (TP01 to TP03) is registered. This product number ID is associated with a component of a T-shirt as a product. For example, the product number IDs "TP01", "TP02", and "TP03" are respectively associated with sewing operations corresponding to the "body", "sleeves", and "collar" of the T-shirt as a product. In the product number ID "TP01", an operation of sewing the front body and the back body is associated. In the product number IDs "TP02" and "TP03", operations of sewing the sleeves and the collar to the front and back body parts are respectively associated. The content of these product number IDs is determined based on information from the PC in the specification generation process 2 and registered based on information from the portable terminal 30 in the cutting process 3.

[0058] In addition, in the production management information table 600, as standard data, standard sewing time is registered, and as standard parameter 1 (parameter 1), standard sewing speed is registered. In standard parameter 1, "TS3" representing a fast sewing time, "TS1" representing a slow sewing time, and "TS2" representing a sewing time in between them are set. In addition, in standard parameter 2, "NS3" representing a fast sewing speed, "NS1" representing a slow sewing speed, and "NS2" representing a sewing speed in between them are set. The content of these standard parameters 1 and 2 is registered based on information from the PC in the specification generation process 2.

[0059] In the production management information table 600, production management information in the case where sewing operations are performed by three different operators using three different sewing machines 9 is registered for each of the product number IDs "TP01", "TP02", and "TP03". Operator IDs (OP1 to OP3) are respectively associated with the three operators. Sewing machine IDs (M1 to M3) are respectively associated with the three sewing machines 9. These operator IDs and sewing machine IDs are preset by the manager of the sewing management system 1 etc. and registered based on information from the sewing machine 9 in the sewing process 4.

[0060] And, in the production management information table 600, the actual sewing time in the sewing machine 9 is registered as operation data 1, and the actual sewing speed in the sewing machine 9 is registered as operation data 2. In addition, the content registered in operation data 1 and 2 is the same as that of standard parameters 1 and 2 respectively. That is, "TS1", "TS2", or "TS3" is registered as the sewing time, and "NS1", "NS2", or "NS3" is registered as the sewing speed. The content of these operation data 1 and 2 is registered based on information from the sewing machine 9 in the sewing process 4.

[0061] Also, the position information of the operator of the sewing machine 9 is registered in the production management information table 600. The content registered in the position information is, for example, registered based on how far it is separated in the east-west-north-south directions with reference to the position of the position detection device 48 provided in the sewing process 4. For example, in the production management information with the number #2, "N1: E1" is registered. This indicates that the operator has moved to a position that is separated 1 block to the north and 1 block to the east from the position of the position detection device 48. Here, "block" refers to a unit of a pre-determined distance. Similarly, in the production management information with the number #6, "N2: W2" is registered. This indicates that the operator has moved to a position that is separated 2 blocks to the north and 2 blocks to the west from the position of the position detection device 48. The content of these position information is registered based on the information from the position detection device 48 in the sewing process 4. In addition, regarding the method for detecting the position of the operator, the movement can also be detected (estimated) by a position detection sensor such as GPS provided in the wearable terminal.

[0062] Also, the production quantity data, inspection result (number of non-conforming products) data, problem (error) data, and completion date and time data of the product (sewn product) are registered in the production management information table 600. The number of products that have been sewn by the sewing machine 9 is registered in the production quantity data, and the inspection result of the product is registered in the inspection result data. The actual number of pieces of the product is registered in the former, and for example, the non-conforming rate (or qualified rate) is registered in the latter. In addition, the number of occurrences of problems in the sewing machine 9 is registered in the problem data, and the date and time when the packaging operation is completed is registered in the completion date and time data. The actual number of occurrences of problems in the sewing machine 9 (for example, feeding error of the sewn product, needle movement error) is registered in the former. The production quantity data is registered based on the information of the sewing machine 9 from the sewing process 4. The content of the inspection result data and the problem data is registered based on the information of the portable terminal 60 from the inspection process 6. The content of the completion date and time data is registered based on the information of the portable terminal 70 from the packaging process 7.

[0063] In Figure 6In the production management information table 600 shown, as shown in numbers #1 to #3, it can be seen that in the product number ID "TP01", three different operators (operators of OP1 to OP3) used three different sewing machines 9 (M01 to M03) to perform the sewing operation of the same process (ST1). In addition, it can be seen that the operators of OP1 and OP2 actually performed the sewing operation with the sewing time of TS3 and the sewing speed of NS3 relative to the sewing time (TS2) and sewing speed (NS2) set in standard parameters 1 and 2. On the other hand, it can be seen that the operator of OP3 actually performed the operation with the sewing time of TS1 and the sewing speed of NS1 relative to the sewing time (TS2) and sewing speed (NS2) set in sewing parameters 1 and 2. These representative sewing times and sewing speeds are different depending on the operator.

[0064] In addition, it can be seen that the operators of OP1 and OP3 did not move from the reference position (the setting position of the position detection device 48), while the operator of OP2 moved 1 block from the reference position to the northeast. In addition, it can be seen that the production data of the products of the operators of OP1, OP2 and OP3 are 100 pieces, 80 pieces and 60 pieces respectively. In addition, it can be seen that the number of unqualified products in the inspection results of the operators of OP1 and OP2 is "0", while the number of unqualified products in the inspection results of OP3 is "3". In addition, it can be seen that no problems occurred in the sewing machines 9 of M01 and M02, while 10 problems occurred in the sewing machine 9 of M03. In addition, it can be seen that the completion time of the products involved by the operator of OP1 is the earliest (11:15 on December 3, 2018), followed by the completion time of the products involved by the operators of OP2 and OP3 (11:30 and 11:45 on the same day, respectively).

[0065] Here, refer to Figure 1 , Figure 5 and Figure 6, the registration method of the production management information described above with respect to the production management information table 600 will be described. For example, in the sewing process 4, if the operator reads the product number ID and the operator ID through the identification information reader unit of the portable terminal 40, these information are output as production management information to the management server 8 and recorded in the storage unit 82. At this time, the sewing machine ID of the sewing machine 9 connected to the portable terminal 40 is also output to the management server 8 and recorded in the storage unit 82. In addition, information such as sewing data and standard parameters output from the specification generation process 2 are also recorded in the storage unit 82. If the product number ID, process ID, operator ID, and sewing machine ID are recorded in the storage unit 82, the form management unit 86 calls the standard parameters 1 and 2 based on the product number ID and registers this information in the production management information table 600. Thus, the product number ID, standard parameter 1, standard parameter 2, operator ID, and sewing machine ID are registered in the production management information table 600.

[0066] Moreover, in the sewing process 4, if the actual sewing operation is performed, the operation data and production data associated with the sewing operation are output to the management server 8 and recorded in the storage unit 82. In addition, the position information of the operator is output from the position detection device 48 in the sewing process 4 to the management server 8 and recorded in the storage unit 82. If they are recorded in the storage unit 82, the form management unit 86 registers the operation data, production data, and the position information of the operator in the production management information table 600. Thus, the operation data 1, operation data 2, the position information of the operator, and the production data are registered in the production management information table 600.

[0067] Also, in the inspection process 6, if the product (sewn product) is inspected, the inspection result data of the product and the problem data in the sewing machine 9 are output from the portable terminal 60 to the management server 8 and recorded in the storage unit 82. If they are recorded in the storage unit 82, the form management unit 86 registers the inspection result data and the problem data in the production management information table 600. Thus, the inspection result data and the problem data are registered in the production management information table 600.

[0068] Also, in the packaging process 7, if the sewing product is packaged, the completion date and time data are output from the portable terminal 70 to the management server 8 and recorded in the storage unit 82. If the completion date and time data are recorded in the storage unit 82, the form management unit 86 registers the completion date and time data in the production management information table 600. Thus, the completion date and time data are registered in the production management information table 600. The entire production management information of the production management information table 600 shown above is registered in the above manner. Figure 6 All the production management information of the production management information table 600 shown is registered.

[0069] In Figure 7In the physical condition management information table 700 shown, biological information (body temperature, heart rate, blood pressure), activity amount information (number of steps), working hours, and rest times of the operator corresponding to each measurement date and time are registered in association with the operator ID. In addition, in the physical condition management information table 700, the physical condition status of the operator obtained by determining these biological information, activity amount information, working hours, and rest times as determination factors is registered.

[0070] In Figure 7 In the physical condition management information table 700 shown, a situation where physical condition management data of the operator with the operator ID "OP1" from 9:00 on June 10, 2019 to 17:00 on June 14, 2019 is registered is shown. In the physical condition management information table 700, biological information, etc. are measured at predetermined fixed times. Specifically, biological information, etc. are measured at 9:00, which is the start time of work in the morning every day, 13:00, which is the start time of work in the afternoon, and at 2-hour intervals after 13:00. The working hours record the elapsed time since 9:00. In addition, the rest times are recorded by counting the rest at lunch, the rest from 15:15 to 15:30, and the rest from 17:30 to 18:00.

[0071] In the physical condition status, multiple levels (level S, A, B, C, D) are registered by comprehensively judging the registered contents of the determination factors. Level S indicates the best physical condition state of the operator. Moreover, in the order of levels A, B, C, D, it indicates that the physical condition of the operator is gradually deteriorating. In addition, regarding the levels of the physical condition status, it is not limited to these, and can be appropriately changed.

[0072] Here, regarding the determination method of the physical condition status, the body temperature and heart rate are taken as examples for explanation. For example, in the physical condition management information table 700, when the body temperature of the operator is 36.5° - 36.8°, it is set as level S. And it is stipulated that when the body temperature is 36.9° - 37.2°, it is lowered by 1 level, when the body temperature is 37.3° - 37.6°, it is lowered by 2 levels, and when the body temperature is greater than or equal to 37.7°, it is lowered by 3 levels. In addition, when the heart rate of the operator is 60 - 69 beats per minute, it is set as level S. And it is stipulated that when the heart rate is 70 - 79 beats per minute, it is lowered by 1 level, when the heart rate is 80 - 89 beats per minute, it is lowered by 2 levels, and when the heart rate is greater than or equal to 90 beats per minute, it is lowered by 3 levels. In the physical condition management information table 700, these factors are comprehensively judged to set the level of the physical condition status.

[0073] For example, in the physical condition management information form 700, in the physical condition management data at #4, the body temperature is 37.0°, and the heart rate is 60 beats. Therefore, with respect to the body temperature, the level is decreased by 1 level, and the physical condition status becomes level A. In the physical condition management data at #13, the body temperature is 37.0°, and the heart rate is 70 beats. Therefore, with respect to the body temperature, the level is decreased by 1 level, and with respect to the heart rate, the level is decreased by 1 level, and the physical condition status becomes level B.

[0074] Similarly, in the physical condition management data at #17, the body temperature is 37.5°, and the heart rate is 70 beats. Therefore, with respect to the body temperature, the level is decreased by 2 levels, and with respect to the heart rate, the level is decreased by 1 level, and the physical condition status becomes level C. In the physical condition management data at #18, the body temperature is 37.7°, and the heart rate is 70 beats. Therefore, with respect to the body temperature, the level is decreased by 3 levels, and with respect to the heart rate, the level is decreased by 1 level, and the physical condition status becomes level D. In the physical condition management data at #22, the body temperature is 37.0°, and the heart rate is 90 beats. Therefore, with respect to the body temperature, the level is decreased by 1 level, and with respect to the heart rate, the level is decreased by 3 levels, and the physical condition status becomes level D.

[0075] Here, for the sake of convenience of explanation, the case of only referring to the body temperature and heart rate in the determination method of the physical condition status is described. In the actual determination method of the physical condition status, other determination factors are also associated for determination. For example, the physical condition status is determined corresponding to the high or low blood pressure of the operator, the length of working hours, and the number of times of obtaining rest time. Thus, the physical condition status corresponding to the operator's physical condition can be further managed on the physical condition management information form 700.

[0076] Here, referring to Figure 8 and Figure 9 , the registration method of the above-mentioned physical condition management data with respect to the physical condition management information form 700 is described. Figure 8 and Figure 9 are flowcharts for explaining an example of the registration process of the physical condition management information according to the present embodiment with respect to the physical condition management information form 700 in the management server 8. In addition, in Figure 8 and Figure 9 , for the sake of convenience of explanation, the process of registering biological information as the physical condition management information is described. In addition, the process of registering the activity amount information as the physical condition management information is the same as that of the biological information, so it is omitted.

[0077] In Figure 8 , the process of accumulating the physical condition management information (biological information) before registering the physical condition management data into the physical condition management information form 700 is shown. On the other hand, in Figure 9In this, a process of registering physical condition management information including the physical condition state is shown based on a determination reference value set according to the accumulated physical condition management information. In addition, in Figure 8 and Figure 9 a situation where biological information is measured by the wearable terminal 10 at a predetermined measurement time is shown.

[0078] As Figure 8 shown, in the wearable terminal 10, the control unit 11 determines whether there is an instruction to start measuring the biological information (physical condition management information) of the operator (step (hereinafter referred to as “ST”) 801). For example, the control unit 11 determines whether an instruction to start measurement is received from the operator via the input unit 14. In addition, the control unit 11 may also determine that it is an instruction to start measuring biological information when the operator ID is read in via the identification information reader unit 15. In the case where an instruction to start measuring biological information is not detected (ST801: No), the control unit 11 continues the determination process of ST801.

[0079] In the case where an instruction to start measuring biological information is detected (ST801: Yes), the control unit 11 determines whether the current time has reached a predetermined measurement time (ST802). Here, 9:00, 13:00, and every two hours after 13:00 are set as the measurement times. The control unit 11 determines the measurement time corresponding to the time information measured by a timing unit (not shown). In the case where the current time has not reached the measurement time (ST802: No), the determination process of ST802 is repeated until it is reached.

[0080] In the case where the current time has reached the measurement time (ST802: Yes), the control unit 11 instructs the sensor unit 16 to acquire biological information. If this instruction is received, the sensor unit 16 acquires biological information (ST803). If the sensor unit 16 acquires biological information, the control unit 11 outputs the biological information acquired via the communication unit 17 and the measurement time of this biological information to the management server 8 (ST804). In the management server 8, this biological information is stored in the storage unit 82. If biological information is stored in the storage unit 82, the table management unit 86 registers it in the physical condition management information table 700 (ST805).

[0081] After outputting the biological information and the measurement time, the control unit 11 of the wearable terminal 10 determines whether there is an instruction to end the measurement of the biological information of the operator OP (ST806). For example, the control unit 11 determines whether an instruction to end the measurement is received from the operator via the input unit 14. In the case where an instruction to end the measurement of the biological information is not detected (ST806: No), the control unit 11 returns the process to ST802 and repeats the processes after ST802. Moreover, if an instruction to end the measurement of the biological information is detected after repeating the processes of ST802 to ST806 (ST806: Yes), the control unit 11 ends Figure 8 the cumulative process of the series of biological information (physical condition management data) shown.

[0082] As described above, in the physical condition management information table 700, the biological information of the operator is continuously registered. If the biological information of the operator is registered, then as Figure 9 shown, the manager of the management server 8 sets a reference value (hereinafter referred to as "judgment reference value") for judging the physical condition state of the operator based on the biological information of the operator registered in the above manner (ST901). For example, preferably, in the judgment reference value, reference values that can separate the physical condition states are set in multiple stages (for example, Figure 7 the five stages of S, A to D shown). In addition, regarding the judgment of the physical condition of the operator based on the biological information, it is also possible to perform the judgment using artificial intelligence (AI) or the like according to a plurality of conditions including the biological information.

[0083] In the state where the judgment reference value of the physical condition state is set in the management server 8 as described above, the biological information (physical condition management data) of the operator is measured. The measurement of the biological information is common to the Figure 8 flow shown. That is, in the state where the judgment reference value of the physical condition is set, it is determined whether there is an instruction to start measuring the biological information (ST801). If it becomes the measurement time (ST802), the biological information is acquired (ST803), and the acquired biological information and the like are output to the management server 8 (ST804) and recorded in the management server 8 (ST805).

[0084] If the biological information and the like output from the wearable terminal 10 are recorded, the table management unit 86 of the management server 8 determines the physical condition state of the operator based on the biological information, and records the determined physical condition state in the physical condition management information table 700 (ST902). Thus, in the physical condition management information table 700, the physical condition state of the operator is registered in association with the biological information of the operator and the measurement time thereof.

[0085] After outputting the biological information and the measurement time, the control unit 11 of the wearable terminal 10 determines whether there is an instruction to end the measurement of the operator's biological information (ST903). For example, the control unit 11 determines whether an instruction to end the measurement is received from the operator via the input unit 14. In the case where an instruction to end the measurement of the biological information is not detected (ST903: No), the control unit 11 returns the process to ST802 and repeats the processes after ST802. Moreover, if an instruction to end the measurement of the biological information is detected after repeating the processes of ST802 to ST804 and ST903 (ST903: Yes), the control unit 11 ends Figure 9 the registration process of the series of biological information (physical condition management information) shown.

[0086] Based on Figure 9 the processes shown, in the sewing management system 1, after being instructed to start the measurement of the biological information, the measurement of the biological information is continued until the measurement is instructed to end, and the biological information and the like are continuously registered in the physical condition management information table 700. In addition, here, the case of registering the biological information as the physical condition management information has been described, but as the activity amount information, the number of steps of the operator can be detected, or the working time and the number of breaks of the operator can be counted. By registering these information, for example, Figure 7 the physical condition management information shown is registered in the physical condition management information table 700.

[0087] In the sewing management system 1 according to the present embodiment, the management server 8 estimates the sewing skills of the operator based on the production management information registered in the production management information table 600, and estimates the production capacity of the operator based on the physical condition management information registered in the physical condition management information table 700. Moreover, the sewing quality and production efficiency in the sewing production line SL are analyzed according to these estimation results. Next, with reference to Figure 10 the analysis process in the management server 8 as described above will be described. Figure 10 is a flowchart for explaining the analysis process in the management server 8 according to the present embodiment.

[0088] As Figure 10As shown, in the management server 8, the control unit 81 monitors whether production management information is always received from the devices of various processes of the sewing management system 1 (ST1001). When production management information is not received from the devices of various processes (ST1001: No), the control unit 81 continues this monitoring operation. In addition, the content of the production management information determined in ST1001 is preset in the management server 8 by the manager of the sewing management system 1 or the like in advance.

[0089] On the other hand, if production management information is received from the devices of various processes (ST1001: Yes), the form management unit 86 registers this production management information in the production management information form 600 (ST1002). Under the control of the control unit 81, the production management information is recorded in the storage unit 82 via the communication unit 85. Here, the form management unit 86 registers the production management information stored in the storage unit 82 in various items of the production management information form 600 based on the product number ID.

[0090] After registering the production management information in the production management information form 600, the control unit 81 monitors whether operator's physical condition management information is received from the wearable terminals 10 of various processes of the sewing management system 1 (ST1003). When the physical condition management information is not received from the wearable terminal 10 (ST1003: No), the control unit 81 returns the process to ST1001 and repeats the processes of ST1001 and subsequent steps.

[0091] On the other hand, if the physical condition management information is received from the wearable terminal 10 (ST1003: Yes), the form management unit 86 registers this physical condition management information in the physical condition management information form 700 (ST1004). Under the control of the control unit 81, the physical condition management information is recorded in the storage unit 82 via the communication unit 85. Here, the form management unit 86 registers the physical condition management information stored in the storage unit 82 in various items of the physical condition management information form 700 based on the operator ID.

[0092] Here, the case where production management information is received and registered in the production management information form 600 (ST1001, ST1002), and then physical condition management information is received and registered in the physical condition management information form 700 (ST1003, ST1004) has been described. However, the order of the reception process and registration process of these management information can also be reversed, or these processes can be performed in parallel.

[0093] During the continuous registration of production management information and physical condition management information, the control unit 81 determines whether it has received an analysis instruction for sewing quality and production efficiency in the sewing production line SL from the manager via the input unit 84 (ST1005). If it has not received the analysis instruction for sewing quality and production efficiency (ST1005: No), the control unit 81 continues this determination operation. During the continuation of this determination operation, the production management information and the physical condition management information are further continuously registered in the production management information table 600 and the physical condition management information table 700.

[0094] If it has received the analysis instruction for sewing quality and production efficiency (ST1005: Yes), the control unit 81 estimates the sewing skills of the operator based on the production management information registered in the production management information table 600 (ST1006). The sewing skills are estimated by comprehensively observing the operator's ability to use various sewing machines, ability to handle various processes, etc. Here, the estimation of the sewing skills for one process will be described. The sewing skills estimated in ST1006 indicate how many products meeting the specified standards can be sewn within a pre-specified time.

[0095] Here, consider the case of estimating the sewing skills of the operator using the production management information with numbers #1 to #3 registered in the production management information table 600 as an example. In this case, the control unit 81 is based on Figure 6 the content of the production management information shown, and estimates that the sewing skills of the operators of OP1 and OP2 are greater than or equal to a certain level. On the other hand, it is estimated that the sewing skills of the operator of OP3 are lower than a certain level.

[0096] For example, the control unit 81 can estimate the sewing skills of the operator based on the content of the operation data 1 and 2 registered in the production management information table 600 (more specifically, the content of the operation data 1 and 2 compared with the standard parameters 1 and 2). In this case, OP1 and OP2 performed operations with the content of the operation data 1 and 2 (TS3, NS3) relative to the content of the standard parameters 1 and 2 (TS2, NS2), while OP3 performed operations with the content of the operation data 1 and 2 (TS1, NS1) relative to the content of the standard parameters 1 and 2 (TS2, NS2). Therefore, the control unit 81 estimates that the sewing skills of the operators of OP1 and OP2 are greater than or equal to a certain level. On the other hand, it is estimated that the sewing skills of the operator of OP3 are lower than a certain level.

[0097] In addition, the control unit 81 can estimate the sewing skills of the operator based on the inspection results of the products of the operator registered in the production management information table 600. In this case, the number of non-conforming products in the inspection results of the products of the operators of OP1 and OP2 is "0", while the number of non-conforming products in the inspection results of the products of the operator of OP3 is "3". Therefore, the control unit 81 estimates that the sewing skills of the operators of OP1 and OP2 are greater than or equal to a certain level. On the other hand, it is estimated that the sewing skills of the operator of OP3 are lower than a certain level. The sewing skills of the operator estimated based on the inspection results of the products can represent the quality (sewing quality) of the products sewn by the operator.

[0098] Moreover, the control unit 81 can estimate the sewing skills of the operator based on the production quantity data registered in the production management information table 600. In this case, the production quantity data of the products of the operators of OP1, OP2, and OP3 are 100 pieces, 80 pieces, and 60 pieces respectively. Therefore, the control unit 81 estimates that in the order of OP1, OP2, and OP3, the sewing skills of the operators decrease in turn. The sewing skills of the operator estimated based on the production quantity data of the products can represent the work efficiency of the operator.

[0099] In addition, when estimating the sewing skills of the operator as described above, the control unit 81 preferably considers the problem data (the number of occurrences of problems that occurred in the sewing machine 9) of the sewing machine 9 determined by the sewing machine ID. For example, by considering the influence of the problem data of the sewing machine 9 on the production quantity data and the inspection result data, the normal sewing skills of the operator can be accurately estimated.

[0100] In the above description, for the sake of convenience of explanation, it has been described that the sewing skills of the operator are greater than or equal to a certain level or lower than a certain level. That is, the case where the sewing skills of the operator are estimated in two stages is shown. However, the estimation criteria for the sewing skills of the operator are not limited to this. In order to accurately estimate the sewing skills of the operator, it is preferably numerically valued according to the benchmarks of multiple stages determined in advance as an implementation manner. In this case, the sewing skills of the operator are numerically valued by comprehensively judging the contents of various production management information included in the production management information table 600.

[0101] For example, consider using the value of the production quantity data in the production management information to add or subtract points according to the content of each item. For example, when reducing the sewing time of the standard parameters 1 and 2 and increasing the sewing speed, points are added respectively (for example, 5 points are added). On the other hand, when increasing the sewing time and decreasing the sewing speed, points are subtracted respectively (for example, 5 points are subtracted). In addition, points are added or subtracted according to the number of non-conforming products in the inspection result data. And the value of the problem data is added points corresponding to that value.

[0102] In the case of adding and subtracting points in the above-described manner, the sewing skills of the operators of OP1, OP2, and OP3 are obtained respectively in the following manner.

[0103] (Sewing skill of the operator of OP1)

[0104] 100 (production data) + 10 (changes in setting parameters 1 and 2) + 0 (inspection result data) + 0 (problem data) = 100

[0105] (Sewing skill of the operator of OP2)

[0106] 80 (production data) + 10 (changes in setting parameters 1 and 2) + 0 (inspection result data) + 0 (problem data) = 80

[0107] (Sewing skill of the operator of OP3)

[0108] 60 (production data) - 10 (changes in setting parameters 1 and 2) - 3 (inspection result data) + 10 (problem) = 57

[0109] Therefore, in this case, it is presumed that the sewing skill of OP1 is the highest, the sewing skill of OP2 is the second highest, and the sewing skill of OP3 is the third highest. The sewing skills presumed in the above-described manner are registered in the sewing skill table 1100 (refer to Figure 11 ). As Figure 11 shown, in the sewing skill table 1100, the sewing skills (more specifically, the values corresponding to the sewing skills) are registered in association with the operator ID and the process ID.

[0110] After the sewing skills of the operators are presumed, the control unit 81 presumes the production capacity of the operator based on the presumed sewing skills of the operator and the current physical condition status of the operator registered in the physical condition management information table 700 (ST1007). The production capacity of the operator can be presumed, for example, by multiplying the value representing the sewing skills of the above-described operator (hereinafter, appropriately referred to as "sewing skill value") by a coefficient corresponding to the physical condition status (hereinafter, appropriately referred to as "status coefficient").

[0111] For example, when the physical condition is "S", "1.2" can be set in the state coefficient; when the physical condition is "A", "1.0" can be set in the state coefficient; when the physical condition is "B", "0.8" can be set in the state coefficient; when the physical condition is "C", "0.6" can be set in the state coefficient; and when the physical condition is "D", "0.4" can be set in the state coefficient. As described above, by multiplying the sewing skill value by the state coefficient, the production capacity of the operator can be accurately estimated according to the physical condition of the operator.

[0112] Moreover, after estimating the production capacity of the operator OP, the control unit 81 analyzes the sewing quality of the sewing production line SL (ST1008). For example, the control unit 81 comprehensively judges the sewing skill of the operator estimated in ST1006 to analyze the sewing quality of the sewing production line SL. For example, the control unit 81 can analyze the sewing quality of the sewing production line SL by considering the above sewing skill values of the operators arranged in the sewing production line SL. If the sewing skill value of the operator is greater than or equal to the specified value, the control unit 81 can analyze that the sewing quality in the sewing production line SL is high; on the other hand, if the sewing skill value is lower than the specified value, the control unit 81 can analyze that the sewing quality in the sewing production line SL is low.

[0113] In addition, when analyzing the sewing quality of the sewing production line SL, as a preferred embodiment, it is preferable to directly multiply the production management information by a coefficient that increases the value of the item representing the sewing quality (for example, the value of the inspection result data). In this case, the sewing quality in the sewing production line SL can be analyzed more accurately.

[0114] After analyzing the sewing quality of the sewing production line SL, the control unit 81 analyzes the production efficiency of the sewing production line SL (ST1009). For example, the control unit 81 comprehensively judges the production capacity of the operator estimated in ST1007 to analyze the operation efficiency of the sewing production line SL. For example, the control unit 81 can analyze the operation efficiency of the sewing production line SL by adding the value representing the production capacity of the operator arranged in the sewing production line SL (production capacity value). If the production capacity value of the operator is greater than or equal to the specified value, the control unit 81 can analyze that the operation efficiency in the sewing production line SL is high; on the other hand, if the production capacity value is lower than the specified value, the control unit 81 can analyze that the operation efficiency in the sewing production line SL is low.

[0115] In addition, when analyzing the operation efficiency of the sewing production line SL, it is preferable as an implementation mode to directly multiply the production management information by a coefficient that increases the value of an item indicating the operation efficiency (for example, the value of production quantity data). In this case, the operation efficiency in the sewing production line SL can be analyzed more accurately.

[0116] By displaying the above analysis results on the display unit 83, the manager of the management server 8 can confirm the analysis results of the sewing quality and production efficiency in the sewing production line SL. Moreover, it is possible to identify the parts with low sewing quality and production efficiency in the sewing production line SL corresponding to the analysis results. Thereby, the manager can implement countermeasures such as reallocating operators or training sewing skills to improve the sewing quality and production efficiency.

[0117] In addition, as an implementation mode, when displaying the analysis results on the display unit 83, it is preferable to change the color scheme of the operator's icon based on the physical condition status of the operators arranged in each process of the sewing production line SL. For example, the icon can be set to green when the physical condition status is "S", and set to blue, yellow, pink, and red when the physical condition status is "A", "B", "C", and "D" respectively. By changing the color scheme of the operator's icon as described above, it is possible to intuitively grasp the physical condition of the operator and also the status of the production efficiency in the sewing production line SL.

[0118] As described above, in the sewing management system 1 according to the present embodiment, for each process of producing products sewn by the sewing production line SL, the production management information including the operator ID and the operation information of the sewing machine 9 is managed, and the physical condition management information is managed for each operator. Moreover, the sewing skills of the operator are estimated based on this production management information, and the production capacity of the operator is estimated based on the physical condition management information. Thereby, by setting the personnel allocation in the sewing production line SL, etc., the sewing quality and production efficiency in the sewing production line SL can be improved.

[0119] In addition, the timing for setting the personnel allocation in the sewing production line SL, etc. can be the timing when the production capacity of the operator decreases. Alternatively, the personnel allocation can be set based on the trend that can be judged from the accumulated data. In addition, based on the accumulated data, using artificial intelligence (AI), etc., the personnel allocation can be set in advance before the production capacity decreases according to the omen of the decrease in the production capacity of the operator.

[0120] Specifically, in the sewing management system 1, the management server 8 determines the physical condition state of the operator based on the physical condition management information, adjusts the sewing skills of the operator according to the physical condition state, and thereby estimates the production capacity of the operator. According to this structure, the sewing skills are adjusted according to the physical condition state determined based on the physical condition management information, and thereby the production capacity of the operator is estimated. Thus, it is possible to accurately estimate the production capacity corresponding to the physical condition of the operator.

[0121] In addition, in the sewing management system 1, the wearable terminal 10 detects the biological information of the operator as an example of the physical condition management information. The management server 8 determines the physical condition state of the operator corresponding to the biological information detected by the wearable terminal 10. Thus, it is possible to accurately determine the physical condition state corresponding to the biological information of the operator.

[0122] Moreover, in the sewing management system 1, the wearable terminal 10 detects the activity amount information of the operator as an example of the physical condition management information. The management server 8 determines the physical condition state of the operator corresponding to the activity amount information detected by the wearable terminal 10. Thus, it is possible to accurately determine the physical condition state corresponding to the activity amount information of the operator.

[0123] In addition, according to the sewing management system 1, on the basis of being able to improve the sewing quality and production efficiency in the sewing production line SL, it is also possible to improve the management efficiency of the business management of the operators working in the sewing production line SL. In Figure 6 the production management information table 600 shown, and Figure 7 the physical condition management information table 700 shown, contents related to the contribution degree in business made by the operator are registered. Specifically, the production capacity of the operator obtained by Figure 10 ST1007 is content directly related to the contribution degree in business. As an implementation manner, it is preferably to judge the salary treatment of the operator, whether to take a vacation, etc. based on these information.

[0124] The technology of the present invention is not limited to the above-mentioned embodiments and modification examples, and various changes, replacements, and deformations can be made without departing from the main idea of the technical idea. And if the technical idea of the present invention can be realized by other means through technological progress or derived other technologies, then that method can be used for implementation. Therefore, the claims cover all embodiments that can be included within the scope of the technical idea of the present invention.

[0125] For example, in the above-described embodiment, the case where the portable terminal 40 connected to the sewing machine 9 reads the operator ID and the product number ID has been described. However, the structure for reading the operator ID and the product number ID is not limited thereto and can be appropriately changed. For example, the sewing machine 9 may also have a structure for reading the operator ID and the product number ID. In addition, in the above-described embodiment, the communication unit 47 for communicating with the management server 8 and the like via the network NW2 of the sewing management system 1 is provided in the portable terminal 40, but the communication unit may also be provided in the sewing machine 9. In addition, in the above-described embodiment, the portable terminals 30, 50, 60, and 70 are configured to be included in various processes constituting the sewing production line SL, but it may also be configured such that when equipment such as a cutting machine, a pressing machine, and an inspection machine used in various processes has a communication function for communicating with the management server 8 and the like via the network, the portable terminals are not provided.

[0126] In addition, in the above-described embodiment, the case where the production management information is managed in units of processes of components constituting the product corresponding to the product number ID through the production management information table has been described. However, the method of managing the production management information is not limited thereto and can be appropriately changed. For example, the production management information may be managed in units of processes of the product corresponding to the product number ID associated with the product.

[0127] Furthermore, in the above-described embodiment, the case where the management server 8 is connected to the network NW2 of the sewing production line SL of the sewing factory SP1 has been described. However, the structure of the management server 8 is not limited thereto and can be appropriately changed. For example, the management server 8 may also be connected to the network NW1 connecting a plurality of sewing factories. In addition, the function of the management server 8 may also be provided in the cloud. In addition, the management server 8 is not limited to being independently configured for the sewing production line SL. For example, the function may also be provided in the PC arranged in the execution area of the specification generation process 2.

[0128] In addition, in the above-described embodiment, the case where the terminal 10 for detecting the physical condition management information of the operator is constituted by the wearable terminal 10 has been described. The case where the body temperature, heart rate, blood pressure, etc. of the operator are detected as the biological information detected by the wearable terminal 10 has been described. As the biological information detected by the terminal 10 (wearable terminal 10), the brain wave may also be detected. By detecting the brain wave, for example, the mental state of the operator can be determined. Thereby, it is possible to determine uneasiness, excitement, etc. felt by the operator. As a result, it is possible to determine the physical condition of the operator including the mental state, and it is possible to more accurately estimate the production ability of the operator.

[0129] In addition, in the above-described embodiment, the case where the operator ID is read from the ID card carried by the operator as identification information has been described, but the operator may also be identified by face authentication, fingerprint authentication, etc. of the operator.

[0130] Further, in the above-described embodiment, the case where the identification information is read by the identification information reader unit 46 of the portable terminal 40 has been described, but the reading of the identification information is not limited to the portable terminal 40, and may also be performed by the sewing machine 9. Figure 12 It is a block diagram showing the structure of the sewing machine 9' included in the sewing management system according to the modification example of the present embodiment. In Figure 12 Regarding the structure common to Figure 2 the same reference numerals are given. As Figure 12 shown, on the basis of the structure shown in Figure 2 the sewing machine 9' further includes an identification information reader unit 98 and a communication unit 99.
