[0025] [Computer System] FIG. 2 is a hardware configuration diagram showing a management controller 6 according to an embodiment. The management controller 6 includes a computer system 1000. The computer system 1000 includes a processor 1001 such as a CPU (Central Processing Unit), a main memory 1002 including a non-volatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory), a storage 1003, and an interface 1004 including an input / output circuit. The functions of the management controller 6 are stored in the storage 1003 as a computer program. The processor 1001 reads the computer program from the storage 1003, expands it in the main memory 1002, and executes processing according to the computer program. The computer program may be distributed to the computer system 1000 via a network.

[0026] 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.

[0027] [Management equipment and sewing machines] 3 is a functional block diagram showing the management device 3 and the sewing machine 2 according to the embodiment. As shown in FIG. 3, the management controller 6 has a normal operation time calculation unit 61, a corrected operation time calculation unit 62, an operation data acquisition unit 63, and an output unit 64.

[0028] The normal operation time calculation unit 61 calculates a normal operation time indicating the time required for a normal operation in which an operator sews the sewing object 100 using the sewing machine 2. The normal operation time calculation unit 61 calculates the normal operation time for each of the multiple sewing machines 2. The normal operation time corresponds to so-called standard time. The normal operation time (standard time) refers to the time required when working in an optimal manner and under optimal conditions. The standard time includes operation time and slack time. The operation time refers to the time required when a worker with standard proficiency works in a standard operating procedure, manner, and conditions. The slack time refers to additional time that appears irregularly or accidentally when performing the work, and time that compensates for a decrease in production due to other factors. The normal operation time may be the accumulated value of the normal operation time for one sewing machine 2.

[0029] The correction work time calculation unit 62 calculates a correction work time indicating the time required for a worker to use the sewing machine 2 to correct the sewing object 100 after normal work has been performed. When there are multiple sewing machines 2 performing correction work, the correction work time calculation unit 62 calculates the correction work time for each of the multiple sewing machines 2. The correction work time corresponds to the standard time required for correction. The correction work time may be a cumulative value of the correction work time for one sewing machine 2.

[0030] The operation data acquiring unit 63 acquires operation data transmitted from the sewing machine controller 8 of the sewing machine 2. The operation data acquiring unit 63 acquires operation data of each of the multiple sewing machines 2.

[0031] The output unit 64 outputs the normal work time calculated in the normal work time calculation unit 61 and the corrected work time calculated in the corrected work time calculation unit 62. In the embodiment, the output unit 64 outputs the normal work time and the corrected work time to the display device 4.

[0032] [Calculation of normal working hours] When normal work is performed on the sewing object 100, an identification tag 101 is attached to the sewing object 100. The identification tag 101 is attached to the sewing object 100 in order to identify the sewing object 100 on which normal work is performed. In the following description, the identification tag 101 attached to the sewing object 100 in order to identify the sewing object 100 on which normal work is performed is appropriately referred to as the normal tag 101.

[0033] When normal work is started on the sewing object 100, the normal tag 101 is identified by the identification device 9. When starting normal work on the sewing object 100, the worker operates a start button provided on the operation panel 7 and causes the identification device 9 to read the normal tag 101 attached to the sewing object 100. After the identification device 9 reads the normal tag 101, the worker starts normal work. The worker makes preparations for sewing the sewing object 100 and sews the sewing object 100 using the sewing machine 2. After the normal work is completed, the worker operates an end button provided on the operation panel 7 and causes the identification device 9 to read again the normal tag 101 attached to the sewing object 100.

[0034] The sewing machine controller 8 transmits to the management controller 6 operation data generated by operating the operation panel 7, and first identification data indicating the identification data of the normal tag 101 by the identification device 9. The management controller 6 transmits operation data generated by operating the start button of the operation panel 7, the first identification data of the normal tag 101 read into the identification device 9 at the start of normal work, operation data generated by operating the end button of the operation panel 7, and the first identification data of the normal tag 101 read into the identification device 9 at the end of normal work.

[0035] The normal work time calculation unit 61 calculates the normal work time based on the first identification data when the identification device 9 identifies the normal tag 101. The normal work time calculation unit 61 can calculate the normal work time based on the first identification data of the normal tag 101 read into the identification device 9 at the start of the normal work and the first identification data of the normal tag 101 read into the identification device 9 at the end of the normal work. In other words, the normal work time calculation unit 61 can calculate the normal work time based on the difference between the time when the normal tag 101 is read into the identification device 9 together with the operation of the start button on the operation panel 7 and the time when the normal tag 101 is read into the identification device 9 together with the operation of the end button on the operation panel 7.

[0036] The normal operation time is calculated for each of the first process (first sewing machine 2A), the second process (second sewing machine 2B), and the third process (third sewing machine 2C).

[0037] The normal operation time calculation unit 61 may calculate the normal operation time based on the operation data acquired by the operation data acquisition unit 63. As described above, the operation data of the sewing machine 2 includes the operating conditions of the sewing machine 2. The operating conditions of the sewing machine 2 include the drive time of the sewing machine motor. The normal operation time calculation unit 61 may calculate the drive time of the sewing machine motor during normal operation as the normal operation time.

[0038] [Calculation of corrective work hours] After normal work has been performed, the sewing object 100 is inspected by an inspector in an inspection process. If a defect is found in the sewing object 100 in the inspection process, it is returned to the sewing process for correction work. When correction work is performed on the sewing object 100, an identification tag 102 is attached to the sewing object 100. The sewing object 100 with the identification tag 102 attached is returned to the sewing process. The identification tag 102 is attached to the sewing object 100 in order to identify the sewing object 100 that will be corrected. In the following description, the identification tag 102 attached to the sewing object 100 in order to identify the sewing object 100 that will be corrected will be referred to as the correction tag 102 as appropriate.

[0039] For example, if a defect caused by the work in the first process is found, the sewing object 100 with the correction tag 102 attached is returned to the first process (first sewing machine 2A). If a defect caused by the work in the second or third process is found, the sewing object 100 with the correction tag 102 attached is returned to the second process (second sewing machine 2B) or third process (third sewing machine 2C). FIG. 1 shows an example in which the sewing object 100 with the correction tag 102 attached is returned to the second process (second sewing machine 2B).

[0040] When correction work is started on the sewing object 100, the correction tag 102 is identified by the identification device 9. When starting correction work on the sewing object 100, the worker operates a start button provided on the operation panel 7 and causes the identification device 9 to read the correction tag 102 attached to the sewing object 100. After the identification device 9 reads the correction tag 102, the worker starts the correction work. The worker makes arrangements for correcting the sewing object 100, or corrects the sewing object 100 using the sewing machine 2. After the correction work is completed, the worker operates an end button provided on the operation panel 7 and causes the identification device 9 to read again the correction tag 102 attached to the sewing object 100.

[0041] The sewing machine controller 8 transmits to the management controller 6 the operation data generated by operating the operation panel 7, and second identification data indicating the identification data of the correction tag 102 by the identification device 9. The management controller 6 transmits the operation data generated by operating the start button of the operation panel 7, the second identification data of the correction tag 102 read into the identification device 9 at the start of the correction work, the operation data generated by operating the end button of the operation panel 7, and the second identification data of the correction tag 102 read into the identification device 9 at the end of the correction work.

[0042] The correction work time calculation unit 62 calculates the correction work time based on the second identification data when the identification device 9 identifies the corrected tag 102. The correction work time calculation unit 62 can calculate the correction work time based on the second identification data of the corrected tag 102 read into the identification device 9 at the start of the correction work and the second identification data of the corrected tag 102 read into the identification device 9 at the end of the correction work. In other words, the correction work time calculation unit 62 can calculate the correction work time based on the difference between the time when the corrected tag 102 is read into the identification device 9 together with the operation of the start button on the operation panel 7 and the time when the corrected tag 102 is read into the identification device 9 together with the operation of the end button on the operation panel 7.

[0043] When there are a plurality of sewing processes (sewing machines 2) in which correction work is performed, the correction work time is calculated for each of the plurality of sewing processes (sewing machines 2).

[0044] The correction work time calculation unit 62 may calculate the correction work time based on the operation data acquired by the operation data acquisition unit 63. As described above, the operation data of the sewing machine 2 includes the operating conditions of the sewing machine 2. The operating conditions of the sewing machine 2 include the driving time of the sewing machine motor. The correction work time calculation unit 62 may calculate the driving time of the sewing machine motor in the correction work as the correction work time.

[0045] [Sewing management method] 4 is a flowchart showing a sewing management method according to the embodiment. The normal operation time calculation unit 61 judges whether or not the first identification data of the normal tag 101 is received (step S1). When it is judged that the first identification data is received in step S1 (step S1: Yes), the normal operation time calculation unit 61 calculates the normal operation time based on the first identification data (step S2). The first identification data is transmitted from the sewing machine controller 8 to the management controller 6 at the start of the normal operation and the end of the normal operation. The normal operation time calculation unit 61 can calculate the normal operation time based on the first identification data received at the start of the normal operation and the first identification data received at the end of the normal operation.

[0046] The correction work time calculation unit 62 determines whether or not the second identification data of the correction tag 102 has been received (step S3). When it is determined in step S3 that the second identification data has been received (step S3: Yes), the correction work time calculation unit 62 calculates the correction work time based on the second identification data (step S4). The second identification data is transmitted from the sewing machine controller 8 to the management controller 6 at the start of the correction work and at the end of the correction work. The correction work time calculation unit 62 can calculate the correction work time based on the second identification data received at the start of the correction work and the second identification data received at the end of the correction work.

[0047] The output unit 64 generates output data based on the normal work time calculated in step S2 and the corrected work time calculated in step S4 (step S5). The output unit 64 outputs the output data to the display device 4 (step S6). In the embodiment, the output data includes display data to be displayed on the display device 4.

[0048] If it is determined in step S1 that the first identification data has not been received (step S1: No), the output data is generated without calculating the normal operation time. If it is determined in step S3 that the second identification data has not been received (step S3: No), the output data is generated without calculating the corrected operation time.

[0049] 5 is a diagram showing an example of display data displayed on the display device 4 according to the embodiment. As shown in FIG. 5, the output unit 64 causes the display device 4 to display the normal work time and the corrected work time. In the example shown in FIG. 5, the output unit 64 causes the display device 4 to display a bar graph showing the relationship between the normal work time and the corrected work time. The manager can recognize the relationship between the normal work time and the corrected work time based on the display data displayed on the display device 4.

[0050] The output unit 64 causes the display device 4 to display the normal work time and the corrective work time for each of the multiple sewing machines 2. Based on the display data displayed on the display device 4, the manager can recognize the relationship between the normal work time and the corrective work time for each of the multiple sewing machines 2.

[0051] The output unit 64 may cause the display device 4 to display the normal work time and the corrected work time for each of a plurality of workers.

[0052] [effect] As described above, according to the embodiment, the sewing management system 1 includes a normal operation time calculation unit 61 that calculates a normal operation time indicating the time required for the normal operation of sewing the sewing object 100 by the worker using the sewing machine 2, a correction operation time calculation unit 62 that calculates a correction operation time indicating the time required for the worker to correct the sewing object 100 using the sewing machine 2 after the normal operation, and an output unit 64 that outputs the normal operation time and the correction operation time. Since not only the time required for the normal operation but also the time required for the correction operation is calculated, the manager can recognize the total operation time including the normal operation time and the correction operation time. The manager can recognize the proportion of the correction operation time in the total operation time. Therefore, the manager can appropriately set up a production plan for sewn products.

[0053] A normal tag 101 for identifying the sewing object 100 on which normal work is performed is attached to the sewing object 100. A correction tag 102 for identifying the sewing object 100 on which correction work is performed is attached to the sewing object 100. The sewing machine 2 has an identification device 9 for identifying the normal tag 101 and the correction tag 102. The normal work time calculation unit 61 can calculate the normal work time based on first identification data when the identification device 9 identifies the normal tag 101. The correction work time calculation unit 62 can calculate the correction work time based on second identification data when the identification device 9 identifies the correction tag 102. In addition, each of the normal tag 101 and the correction tag 102 includes product number data of the sewing object 100, and display data showing the relationship between the product number, the normal work time, and the correction work time is displayed on the display device 4, so that the administrator can manage the normal work time and the correction work time for each product number.

[0054] A plurality of sewing machines 2 are provided. The output unit 64 causes the display device 4 to display the relationship between normal work time and correction work time for each of the plurality of sewing machines 2. The manager can manage the normal work time and correction work time for each sewing machine 2. Furthermore, the relationship between normal work time and correction work time is displayed on the display device 4 for each of the plurality of workers, so that the manager can manage the normal work time and correction work time for each worker. The manager can judge the ability of the worker and determine the remuneration for the worker based on the relationship between the worker and the normal work time and the correction work time. The manager may judge that the shorter the correction work time, the higher the ability of the worker. The manager may increase the remuneration for the worker based on the shorter the correction work time.

[0055] [Another embodiment] In the above-described embodiment, the correction work time calculation unit 62 may calculate the frequency of correction work in a predetermined period (for example, one day or one week). The correction work time calculation unit 62 may calculate the frequency of correction work for each sewing machine 2 or for each worker.

[0056] In the above-described embodiment, at the start of normal work and correction work, the start button on the operation panel 7 is operated and the identification tag (101, 102) is read by the identification device 9, and at the end of normal work and correction work, the end button on the operation panel 7 is operated and the identification tag (101, 102) is read by the identification device 9. It is sufficient for the management controller 6 to recognize the start and end of the normal work and correction work, and the operation panel 7 does not need to be operated.
