Description

[Technical field]

[0001] The present invention relates to an operation management system for managing devices installed in a business establishment such as a factory, a control method for the operation management system, and a control program for the operation management system. [Background technology]

[0002] There have been conventional proposals for efficiently detecting and dealing with abnormalities in devices in factories and the like (for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 2022-149300 Summary of the Invention [Problem to be solved by the invention]

[0004] However, all of these proposals involve costly and complicated systems, making them difficult to implement in small factories and the like. On the other hand, even if the factory is small, when an abnormality occurs in the equipment in which many machines are in operation, it is necessary to quickly discover and resolve the abnormality, which inevitably leads to a problem of a large number of workers in the factory.

[0005] Therefore, the present invention aims to provide an operation management system, an operation management system control method, and an operation management system control program that enable a small number of workers to efficiently manage the operating status of a large number of devices in a business establishment such as a factory without using complex systems, etc.

[0006] The object, according to the present invention, is to provide a business management system including a plurality of machines arranged in a business establishment, a mobile terminal carried by a worker who works on the machines, and a management device capable of communicating with the machines and the mobile terminal, wherein the machines have a warning unit that indicates an abnormal state of operation, and a transmission unit that transmits abnormal state information that is information on the abnormal state to the management device, the management device has a task information generation unit that generates unaccepted task information to be displayed on the mobile terminal based on the abnormal state information of the machines, and the mobile terminal transmits acceptance information to accept the unaccepted task information to the management device. When the acceptance information is sent, the unaccepted task information of the equipment that is the subject of the acceptance information is changed to accepted task information and displayed on the mobile terminal, and the mobile terminal that sent the acceptance information displays a report display section related to the equipment that is the subject of the acceptance information, the report display section having not only completion report information, which is the elimination of the abnormal condition, but also return report information, which is the inability to eliminate the abnormal condition, and when the return report information is sent to the management device, the management device changes the accepted task information of the equipment related to the return report information to unaccepted task information.

[0007] According to the above configuration, the management device has a task information generation unit (task card generation unit, etc.) that generates unaccepted task information (task name on the unaccepted screen, etc.) to be displayed on a mobile terminal based on abnormal status information of the equipment (warp thread breakage, etc.). As a result, information about equipment in an abnormal state is displayed on the mobile device carried by each worker, allowing workers at the business premises to quickly identify which equipment is in an abnormal state. In addition, when any mobile terminal transmits acceptance information to accept unaccepted task information to the management device, the unaccepted task information of the device that is the subject of the acceptance information is changed to accepted task information and displayed on the mobile terminal (e.g., an acceptance screen). As a result, workers who have mobile terminals other than the one that sent the acceptance information are notified that the worker is already on his way to work, thereby preventing the occurrence of an inefficient situation in which multiple workers are heading to one device. In addition, the mobile terminal that has transmitted the underwriting information displays a report display section (report screen or the like) regarding the device that is the subject of the underwriting information. Therefore, the worker using the mobile terminal that transmitted the underwriting information can quickly report the results of the work.

[0008] Furthermore, according to the above configuration, the report display unit has not only completion report information (completion, etc.) which is the elimination of the abnormal condition, but also return report information (return, etc.) which is the inability to eliminate the abnormal condition, and when the return report information is transmitted to the management device, the management device changes the accepted task information of the equipment related to the return report information to unaccepted task information. Therefore, even if a particular worker is unable to resolve the abnormality in the equipment, another worker can quickly move to that equipment. As described above, according to the present invention, even in a business establishment such as a factory, a small number of people can efficiently operate a large number of machines such as looms. In addition, a small number of people can operate a large number of machines (looms, equipment, etc.) efficiently within the business premises.

[0009] Preferably, the task information generation unit of the business management system is characterized in generating task card information including the abnormal state information for each piece of equipment, difficulty level information for resolving the abnormal state, and priority information relative to other pieces of equipment.

[0010] According to the above configuration, the task information generation unit (task card generation unit, etc.) generates task card information including abnormal condition information for each piece of equipment (waiting to be weaved, etc.), difficulty information for resolving the abnormal condition, and priority information in relation to other equipment. Therefore, a worker who visually checks the mobile terminal can easily and quickly determine whether or not he or she is able to resolve the abnormal condition, and can efficiently resolve the abnormal condition of the equipment.

[0011] Preferably, when the completion report information is selected from the report display section displayed on the mobile terminal of the business management system and the completion report information is sent to the management device, related task information regarding the equipment that is the subject of the completion report information can be displayed continuously.

[0012] According to the above configuration, when the completion report information is transmitted to the management device, related task information (unloading, cleaning, etc.) relating to the device that is the subject of the completion report information can be displayed continuously. This allows the equipment to operate more efficiently.

[0013] Preferably, the task card information for all of the equipment at the business establishment of the business management system is configured to be displayed on a large display unit visible to workers working at the business establishment, and on a display unit of a terminal of a manager at the business establishment, and the manager's terminal is configured to be able to instruct the management device to display the task card information on the mobile terminal.

[0014] According to the above configuration, task card information for all of the equipment at the business establishment is displayed on a large display unit (such as a large display) that can be viewed by workers working at the business establishment, and on the display unit of the business establishment's manager's terminal (such as a factory manager's PC). Therefore, workers and managers at the business establishment can always grasp the status of each device.

[0015] Also, according to the above-mentioned configuration, the terminal of the manager is configured to be able to instruct the management device to display the task card on the mobile terminal. Therefore, the manager's terminal can display the task card on the mobile terminal at any time as needed and give instructions on work, etc. Furthermore, workers who receive instructions can work efficiently by acting based on the task cards displayed on their own mobile terminals.

[0016] Preferably, the management device of the business management system has an equipment operation status information storage unit that stores the operation status of the equipment, and a mobile terminal history information storage unit that stores history information of the mobile terminal, and is characterized in that it generates numerical analysis information based on information from the equipment operation status information storage unit and the mobile terminal history information storage unit.

[0017] According to the above configuration, by generating numerical analysis information (such as data for each loom) based on information stored in the equipment operating status information storage unit and the mobile terminal history information storage unit, more appropriate work standards, etc. can be created easily and quickly.

[0018] The object, according to the present invention, is to provide a method for controlling a business management system including a plurality of devices arranged in a business establishment, a mobile terminal carried by a worker who works on the devices, and a management device capable of communicating with the devices and the mobile terminal, wherein a warning unit of the devices indicates an abnormal operation state, a transmission unit of the devices transmits abnormal state information, which is information on the abnormal state, to the management device, and a task information generation unit of the management device displays unaccepted task information on the mobile terminal based on the abnormal state information of the devices, and when the mobile terminal transmits acceptance information to the management device to accept the unaccepted task information, This is achieved by a control method for a business management system, characterized in that the unaccepted task information of the equipment that is the subject of the acceptance information is changed to accepted task information and displayed on the mobile terminal, and the mobile terminal that sent the acceptance information displays a report display section related to the equipment that is the subject of the acceptance information, the report display section having not only completion report information that is the elimination of the abnormal condition, but also return report information that is the inability to eliminate the abnormal condition, and when the return report information is sent to the management device, the management device changes the accepted task information of the equipment related to the return report information to unaccepted task information.

[0019] The object, according to the present invention, is to provide a business management system including a plurality of machines arranged in a business establishment, a mobile terminal carried by a worker who works on the machines, and a management device capable of communicating with the machines and the mobile terminal, the business management system having a function in which a warning unit of the machines indicates an abnormal operation state, a transmission unit of the machines transmits abnormal state information that is information on the abnormal state to the management device, and a task information generation unit of the management device displays unaccepted task information on the mobile terminal based on the abnormal state information of the machines, and when the mobile terminal transmits acceptance information to the management device to accept the unaccepted task information, This is achieved by a control program of a business management system for realizing the following function: the unaccepted task information of a certain device is changed to accepted task information and displayed on the mobile terminal, and the mobile terminal that sent the acceptance information displays a report display section related to the device that is the subject of the acceptance information; the report display section has not only completion report information, which is the elimination of the abnormal condition, but also return report information, which is the inability to eliminate the abnormal condition; and when the return report information is sent to the management device, the management device changes the accepted task information of the device related to the return report information to unaccepted task information.

[0022] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments described below are preferred specific examples of the present invention, and therefore various technically preferable limitations are imposed thereon. However, the scope of the present invention is not limited to these embodiments unless otherwise specified in the following description to the effect that the present invention is limited thereto.

[0023] (Main components of the Loom Management System 1) FIG. 1 is a schematic diagram showing the main configuration of a "business management system" of the present invention, for example, a "loom management system 1." As shown in FIG. 1, the loom management system 1 of this embodiment is a system for efficiently managing the operation of equipment located in a business establishment, such as a loom factory 2, for example, looms (equipment names R01 to S20) that weave woolen fabrics.

[0024] The system 1 includes, for example, a task card management server 10 which is a management device that manages the entire system 1, and has, for example, 40 looms (R01 to S20) arranged in a loom factory 2. FIG. 2 is a diagram showing an example of the arrangement of the looms (R01 to S20) in the loom factory 2 of FIG. As shown in FIG. 2, the weaving factory 2 is configured to be capable of operating a large number of looms, for example, 40 looms (such as R01) simultaneously. In addition, in FIG. 1, only six looms such as R01 are illustrated.

[0025] The system 1 also has a mobile terminal 3 carried by a worker who performs work related to the loom R01 in the loom factory 2, such as a staff member, or an expert related to the loom R01, such as an engineer.

[0026] The system 1 also has a large display unit, such as a large display device 5, which is installed in the weaving factory 2 and shows the operating status of looms R01 and the like in the weaving factory 2, and is installed in a position that is easily visible to staff, engineers, and the like in the weaving factory 2. The system 1 also includes a factory manager's PC 6, which is a computer for a manager of the weaving factory 2, such as the factory manager, and a manager's PC 7, which is a computer for other managers. Furthermore, there is no limit to the number of displays or mobile devices that can be displayed by this system 1, and if the server is placed in the cloud, it will be possible to check and operate abnormal conditions and tasks of looms R01, etc., even from geographically distant locations.

[0027] As shown in Figs. 1 and 2, all of the looms R01 and the like have warning units, such as equipment warning lights 8a to 8f, which are activated when an abnormal state or the like occurs in the looms R01 and the like.

[0028] The task card management server 10, loom R01, mobile terminal 3, factory manager's PC 6, and administrator's PC 7 in Figure 1 each have a computer, including a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a hard disk, etc., and are connected via a bus.

[0029] (Main configuration of task card management server 10) FIG. 3 is a schematic block diagram showing the main configuration of the task card management server 10 of FIG. As shown in Figure 3, the task card management server 10 has a server-side control unit 11, which controls a "server-side communication device 12" for communicating with the outside, a display unit for displaying various information, such as a "server-side display 13," and a "server-side various information input device 14" for inputting various information. The control unit 11 also controls the equipment operation status information storage units shown in Figure 2, such as the "loom operation status information storage unit 15," "special cause judgment unit (program) 16," "task card generation unit (program) 17," "task card change unit (program) 18," "related task selection unit (program) 19," and "history information storage unit 20," which will be described later.

[0030] (Main components of loom R01, etc.) FIG. 4 is a schematic block diagram showing the main configuration of the loom R01 and the like. Since the looms R01 and the like shown in FIG. 1 have the same configuration, the configuration of the loom R01 will be described below as an example. As shown in FIG. 4, the loom R01 has a transmitting unit, for example, a loom-side control unit 101, which has a "loom-side communication device 102" for communicating with other devices, and a "loom-side display 103" for inputting and displaying various information.

[0031] The loom R01 also has a warp supply sensor 105 and a weft supply sensor 106 shown in FIG. 4, which are controlled by the control unit 101. The "warp supply sensor 105" and the "weft supply sensor 106" are disposed in the "warp supply portion" and the "weft supply portion" of the loom R01, respectively. As shown in FIG. 4, the loom R01 also has an "operational state grasping unit (program) 107" and is controlled by the control unit 101. The "operational status grasping unit 107" is configured to determine the presence or absence of an abnormal state such as "warp yarn breakage" or "weft yarn breakage" based on the output signals from the "warp yarn supply sensor 105" and the "weft yarn supply sensor 106", as described below.

[0032] In this embodiment, an example has been described in which the loom R01 is equipped with an "operational status grasping unit 107." However, the present invention is not limited to this, and the "task card management server 10" may also be configured to be equipped with an "operational status grasping unit." In this case, the management server 10 receives output signals from the "warp supply sensor 105" and the "weft supply sensor 106" of the loom R01, and the "operation status grasping unit" judges whether or not there is an abnormal state such as "waiting to weave," "warp broken," or "weft broken." As shown in Figs. 1, 2 and 4, the loom R01 is provided with an equipment warning light 8a.

[0033] (Display 3a of mobile terminal 3, etc.) As shown in FIG. 1, the mobile terminal 3, large display device 5, factory manager's PC 6, and administrator's PC 7 in FIG. 1 each have displays 3a, 5a, 6a, and 7a, for example, which are display units for displaying various information.

[0034] (From raw wool to yarn) In this embodiment, a woolen fabric loom R01 and the like operating in a weaving factory 2 will be taken as an example for explanation, and the "process from raw wool to yarn" will be taken as an example for explanation below. First, in the "pre-spinning process," uniform rovings are made from raw wool, and then in the "spinning process," the yarn is stretched to the desired thickness using a "spinning frame" and twisted to produce "singles." The two yarns are then twisted together to form a two-ply yarn, producing a yarn.

[0035] (Woolen fabric manufacturing process) Next, the process of manufacturing a woolen fabric by putting the produced yarn on a loom R01 or the like will be described. FIG. 5 is a schematic flow chart showing the main steps in the manufacture of woolen fabric. In step (hereinafter referred to as "ST") 1 in FIG. 5, a "work in progress" is executed. In this process, the warp threads are wound with a uniform tension according to the fabric design, such as the number of threads, length, and width, and the warped "warp threads" are set on the loom, such as the R01 loom.

[0036] Next, the process proceeds to ST2, where the "weaving process" is executed. ST2 is the process of combining warp and weft threads to weave, and ends with the production of a woven fabric of a specified length (for example, one bolt of cloth).

[0037] Next, the process proceeds to ST3. In ST3, the "table lowering process" is carried out. In ST3, once a bolt of wool has been produced, it is removed from the loom stand.

[0038] Next, the process proceeds to ST4. In ST4, a "cleaning process" is carried out. In ST4, the looms R01, etc. are cleaned and become "empty looms," completing the entire woolen fabric manufacturing process.

[0039] (Example of operation of the woolen weaving machine management system 1 according to the present embodiment) All 40 looms R01, etc. will be in operation, but in this embodiment, an example will be described below in which an abnormality occurs in four looms (equipment names R02, R03, R04, R05) in the loom factory 2 in Figure 1. Specifically, the example shows a loom (equipment name R02) experiencing an abnormal condition of "warp thread broken" during the weaving process, a loom (equipment name R03) experiencing a state of "waiting to weave" during the in-process process, a loom (equipment name R04) experiencing a "weft thread broken" during the weaving process, and a loom (equipment name R05) experiencing a "warp thread broken" during the weaving process.

[0040] FIG. 6 is a schematic flow chart showing an example in which an abnormal state occurs in a loom (R02, etc.). In ST11, the “operation status grasping unit 107” of each loom (R02, etc.) in FIG. 3 operates to generate information on the presence or absence of abnormal status information such as waiting for weaving for each loom (R02) based on the outputs of the “weaving operation sensor 104”, “warp supply sensor 105”, “weft supply sensor 106”, etc., and transmits the generated abnormal status information to the task card management server 10. Furthermore, each loom (R02, etc.) turns on a corresponding colored light among the "equipment warning lights 8b, etc." installed on each loom (R02, etc.) based on the content of the abnormal state information.

[0041] Specifically, the details are as follows: (For looms (R03, R04)) In the looms (R03, R04), a "weft thread breakage" occurs during the "weaving process", so the "operation status grasping unit 107" operates and, based on the signal from the "weft thread supply sensor 106", determines that the weft thread breakage is an example of abnormal status information, and turns on the "equipment warning light 8d" in Figure 6.

[0042] FIG. 7 is a schematic perspective view showing the facility warning lights 8a (b, c, d, e, f, etc.). As shown in FIG. 7, the entire device is cylindrical and is divided into, for example, three parts. In other words, the top row is yellow Y (hatched from the top right to the bottom left in Figure 6), the middle row is blue B (hatched from the top left to the bottom right in Figure 6), and the bottom row is red R (horizontal lines in Figure 6), and each color emits and rotates independently. Also, yellow Y indicates "broken weft thread," blue B indicates "broken warp thread," and red R indicates "machine trouble."

[0043] In the above-mentioned looms (R03, R04), due to a “weft thread breakage”, the yellow Y light (hatched from the upper right to the lower left of the figure) is turned on and an abnormality signal for “weft thread breakage” is generated and sent to the task card management server 10.

[0044] (For looms (R02, R05)) In the looms (R02, R05), a warp thread breaks during the "weaving process", causing the "operation status grasping unit 107" to operate and, based on the signal from the "warp thread supply sensor 105", determine that the abnormal condition is "warp thread broken". The unit turns on the blue B light in Figure 6 (hatched from the upper left to the lower right of the figure) of the "equipment warning lights 8b, 8e", and generates an abnormal signal for "warp thread broken" and sends it to the task card management server 10.

[0045] In addition, in this embodiment, an example has been described in which the "facility warning lights 8a, etc." are divided into three stages, but the present invention is not limited to this, and the lights may be divided into two stages, four stages, or any other number of stages. In addition, in the present embodiment, the facility warning light 8a and the like are lit up to warn the user, but the present invention is not limited to this, and the warning may be given by flashing lights or a combination of multiple lights.

[0046] Next, the process proceeds to ST12. In ST12, the task card management server 10 stores the "abnormal signal (warp thread breakage, etc.)" received from the loom (R02, etc.) in the loom operation status information storage unit 15, and displays the operation status of each loom (R01, etc.) on the displays 5a, 6a, and 7a of the large display device 5, the factory manager's PC 6, and the administrator's PC 7 in Fig. 1, as well as on the display 3a of the mobile terminal 3, as shown in Fig. 8.

[0047] FIG. 8 is a schematic explanatory diagram showing an example of the operation state information of each loom (R01, etc.) displayed on the display 5a, etc. of the large-scale display device 5. As shown in FIG. As shown in FIG. 8, the operating status information such as "normal operation", "warp thread broken", "weft thread broken", etc. is displayed for each loom (R01, etc.). In this embodiment, the loom (R01) is displayed as "normal operation", the loom (R02) as "warp thread broken", the loom (R03) as "weft thread broken", the loom (R04) as "weft thread broken", the loom (R05) as "warp thread broken", etc.

[0048] Moreover, this operating status information is displayed simultaneously for all looms (R01, etc.), 40 looms (R01, etc.) in this embodiment. Therefore, staff, the factory manager, or the manager who sees the display 5a etc. can instantly grasp the operating status of all the looms (R01 etc.). In particular, since the large display device 5 is installed in a location within the weaving factory 2 where it can be easily seen by many staff members, etc., the staff members within the weaving factory 2 can easily grasp the operating status of all the looms R01, etc.

[0049] In addition, in this embodiment, for looms (R02, etc.) that have a high priority for resolving abnormal conditions, "Priority" is displayed, which is an example of priority information in relation to other looms. Specifically, as shown in FIG. 8, since the "priority" of the "warp thread breakage" of the loom (R02) is high, the display 5a of the large display device 5 etc. displays the loom (R02) as "priority."

[0050] Next, the process proceeds to ST13. In ST13, the task card management server 10 operates the "special cause determination unit (program) 16" in Fig. 3 to determine whether the content of the abnormality signal (such as warp thread breakage) is due to a special cause. Here, "special cause" refers to, for example, a machine shutdown caused by the inspection department, and does not refer to an abnormal condition such as a breakdown of the loom (R01, etc.). Stopping of a loom (R01, etc.) due to such a "special cause" is excluded from the abnormal state since it does not pose any particular problem, and the following process is carried out.

[0051] If in ST13 "the content of the abnormality signal (warp thread breakage, etc.) is not due to a special cause", proceed to ST14. In ST14, a task information generating section of the task card management server 10 in Fig. 3, for example, a "task card generating section (program) 17", operates and displays the "task information" as a "task card" on the display 3a of the mobile terminal 3, as shown in Fig. 9. The task card is also displayed on the displays 5a, 6a, and 7a of the large display device 5, the factory manager's PC 6, and the administrator's PC 7. FIG. 9 is a schematic explanatory diagram showing a "task card" displayed on the display 3a of the mobile terminal 3 or the like.

[0052] In this embodiment, this "task card" includes "task information," which is information requesting a response to a loom (e.g., R02) that has experienced an abnormal condition such as warp thread breakage, and, for example, as shown in FIG. 9, displays the loom equipment name (e.g., R02), task name (e.g., warp thread breakage), task difficulty (an example of difficulty information) (e.g., 1), and "priority (yes or no)."

[0053] The task card also displays a "task status list" that indicates whether the displayed task information is unaccepted task information, such as "unaccepted," accepted task information and accepted information, such as "accepted," "reported," "work status," etc. In Fig. 9, for example, task information "unaccepted" is displayed.

[0054] In this manner, in this embodiment, information about the loom (R02, etc.) in which an abnormal condition has occurred is displayed on each mobile terminal 3 as a "task card," so that each staff member or engineer can easily understand the abnormal condition of the loom (R02, etc.).

[0055] On the other hand, if in ST13 the "special cause judgment unit (program) 16" judges that the abnormal signal from the loom is based on a special cause, the process proceeds to ST14, where the "task card generation unit 17" displays a "task card", which is the abnormality information of the loom, only on the engineer's mobile terminal 3. In this embodiment, in ST14, the "task card", which is abnormality information about the loom, is displayed only on the engineer's mobile terminal 3. However, the present invention is not limited to this, and the card may be sent to a mobile terminal of a staff member other than the engineer. Also, a configuration may be adopted in which the judgment of the special cause judgment unit in ST13 is not performed.

[0056] This allows the abnormal state of the loom to be notified only to the engineers who are able to respond, enabling a quick and appropriate response.

[0057] Next, an example of an operation performed by staff A who has visually checked the "task card" on the mobile terminal 3 in response to abnormality information on a loom (such as R02) will be specifically described below. 10 and 11 are schematic flow charts showing an example of an operation performed by staff A in response to abnormality information of a loom (R02, etc.).

[0058] First, in ST21 of FIG. 10, for example, four "task cards" are displayed on the display 3a of the mobile terminal 3 of staff A as shown in FIG. Specifically, they are "loom (R02), task name (warp thread broken), difficulty level (1), priority level (yes)", "loom (R03), task name (weft thread broken), difficulty level (1), priority level (none)", "loom (R04), task name (weft thread broken), difficulty level (1), priority level (none)", and "loom (R05), task name (warp thread broken), difficulty level (1), priority level (none)".

[0059] Next, the process proceeds to ST22. In ST22, since staff member A is located near the looms (R02, R03, R04, R05) and the difficulty level of the tasks on the task cards is all "1," it is determined that all of the tasks can be solved by staff member A. In addition, since the loom (R02) has a high priority, staff member A selects the loom (R02) task from the four tasks displayed on the task card and decides to head to the loom (R02). Then, select and input (tap) “Accept” which is displayed corresponding to the task of the loom (R02) on the task card in FIG.

[0060] Next, the process proceeds to ST23. In ST23, when the selection input of “Accept” for the loom (R02) is executed on the mobile terminal 3 of staff A, the signal is transmitted to the task card management server 10.

[0061] Next, proceed to ST24. In ST24, the "task card change unit (program) 18" of the task card management server 10 operates to delete and change the task card of the loom (R02) displayed on all mobile terminals 3 from "Not accepted" in FIG. On the other hand, the task card for the loom (R02) is displayed on the staff mobile terminal 3 of staff A in the "Accepting screen" as shown in FIG.

[0062] FIG. 12 is a schematic explanatory diagram showing a task card in the “undertaken” state displayed on the mobile terminal 3. As shown in FIG. In this manner, in this embodiment, other staff members other than staff A can know that a staff member has gone to resolve the abnormality of the loom (R02) in question, which prevents other staff members from going to resolve the abnormality in the same way, thereby enabling the loom factory 2 to be operated efficiently.

[0063] Next, the process proceeds to ST25. In ST25, staff A goes to the loom (R02) and begins the operation to eliminate the abnormal state of "warp thread breakage."

[0064] Next, the process proceeds to ST26. In ST26, when staff A resolves the abnormal condition of "warp thread break" and reports the same, he / she selects (tap) "Report" on the "Task Card" of the loom (R02) on the "Accepting screen" in FIG.

[0065] Next, proceed to ST27. In ST27, the "task card change unit 18" of the task card management server 10 in Fig. 3 operates, and upon receiving a "report" signal for the task card of the loom (R02), a report display unit, for example a report screen, is displayed on the mobile terminal of staff A, as shown in Fig. 13.

[0066] FIG. 13 is a schematic explanatory diagram showing an example of a report screen displayed on the mobile terminal 3. As shown in FIG. As shown in FIG. 13, the report screen specifically displays expert request information such as “Engineer Request,” completion report information such as “Completion,” “False Report,” and “Manual Stop Recovery,” and withdrawal report information such as “Return.” Of these, "Completion" is a report that the abnormal condition has been resolved, and "Resignation" is a report that the abnormal condition cannot be resolved.

[0067] In this manner, in this embodiment, staff A can quickly report to the task card management server 10 information on whether the abnormal state of the loom (R02) has been resolved or cannot be resolved.

[0068] Next, the process proceeds to ST28. In ST28, since staff A in this embodiment has resolved the abnormal state of "warp thread breakage" of the loom (R02), he / she selects and inputs (taps) "Complete" on the "Report screen" in FIG.

[0069] Next, the process proceeds to ST29. In ST29, the "related task selection unit (program) 19" of the task card management server 10 in Fig. 3 operates to refer to the "loom operating state information storage unit 15" of the loom (R02) and determine whether or not there is further "task information."

[0070] In this embodiment, since the production of "one bolt" of woolen fabric on the loom (R02) has been completed, a further task card "Laying the loom" is displayed on the mobile terminal 3 of staff member A. This "table removal" is an example of related task information. Furthermore, this "unloading" refers to the task of "unloading" the woolen fabric from the loom when the weaving of, for example, one bolt of woolen fabric is completed.

[0071] In this manner, in this embodiment, when one "task" is completed, task information related to this completed "task" is successively displayed on the mobile terminals 3 of all staff members, so that the loom (R02) can be operated extremely quickly and efficiently.

[0072] Next, the process proceeds to ST30. In ST30, staff member A selects "Accept" for the task "Unload the Table", and when the task "Unload the Table" is completed, selects "Complete" on the task card on the report screen.

[0073] Next, proceed to ST31. In ST31, the "related task selection unit 19" of the task card management server 10, which has received the completion signal, operates again and refers to the "loom operating state information storage unit 15" of the loom (R02) to determine whether or not there is further task information.

[0074] In this embodiment, since the "unloading" of the loom (R02) is completed in ST30, a task card for the loom (R02), for example, "cleaning", is displayed on the mobile terminals 3 of all staff members.

[0075] Next, the process proceeds to ST32. In ST32, staff member A selects "Accept" for "Cleaning" on the task card for the loom (R02), and when the "Cleaning" task is completed, selects "Complete" on the task card on the report screen.

[0076] In this manner, in this embodiment, tasks can be instructed to staff members in succession for the same loom (R02) with extremely high efficiency.

[0077] Next, the process proceeds to ST33. In ST33, each mobile terminal 3 transmits its history to the task card management server 10, and the task card management server 10 stores the received history information in the "history information storage unit 20".

[0078] In this embodiment, the history information of the mobile terminal 3 is transmitted to the task card management server 10 in a lump sum in ST33, but the present invention is not limited to this, and the history information of the mobile terminal 3 may also be configured to be transmitted to the task card management server 10 each time.

[0079] In addition, in this embodiment, an example has been shown in which staff A is assigned to perform additional tasks related to the loom (R02) in ST29 and ST31, but the present invention is not limited to this, and the additional tasks may be displayed on the mobile terminal 3 of another staff member, and the other staff member may be assigned to execute the tasks.

[0080] On the other hand, if staff A is having difficulty in executing the task of "warp thread break" (resolving the abnormality) of the loom (R02) in ST28 and is unable to complete the task, and therefore needs an "engineer," he or she selects "Request an Engineer" on the report screen in Figure 13. In this case, the task card management server 10 displays on the mobile terminal 3 of the engineer a task card indicating that the task is an "engineer task" that cannot be resolved by the staff.

[0081] Also, when staff A cannot resolve the "warp thread break" of the loom (R02) and cannot decide whether to "request an engineer," he or she selects "return" in FIG. Then, the task card management server 10 changes the "warp broken" status of the loom (R02) from "undertaken" to "not undertaken" and displays it again on each mobile terminal 3.

[0082] Therefore, in this case, the staff members other than staff member A can quickly begin to resolve the abnormal situation.

[0083] In addition, in this embodiment, not only is a "task card" generated on each mobile terminal 3 in response to an abnormal condition signal from each loom (R02, etc.), but a factory manager, for example, can also input a "setup task based on the production plan" or a "stop adjustment task from fabric inspection" from the factory manager's PC or the like to the task card management server, thereby causing a "task card" to be displayed on each mobile terminal 3.

[0084] Furthermore, in this embodiment, the task card management server 10 generates various numerical analysis information based on the data in the "loom operating status information memory unit 15" of the task card management server 10 in Figure 3, which stores the "operating status" of each loom (R01, etc.), and the data in the "history information memory unit 20" stored in each mobile terminal 3. In the present embodiment, the "history information storage unit 20" stores not only the history information of the mobile terminal 2, but also the history information of the factory manager's PC 6, the manager's PC 7, and the like.

[0085] For example, it is possible to generate analytical information that combines "data for each loom (R01, etc.) (time when the loom is empty / time when the loom is left idle for a short period of time, etc.)," ​​"data for each task (amount of tasks generated, time required, etc.)," ​​and "personal data of staff, etc. (type and amount of tasks completed, time required, etc.)."

[0086] This can be used for various process analyses, such as researching staff who are good at specific tasks. In other words, the work results of each staff member can be determined from the type and amount of tasks completed by each staff member and the time required for each task, and this can be used as information for optimal staff allocation and incentives.

[0087] In addition, by knowing the amount of tasks generated for each loom (such as R01) and the time required for them to be generated (for example, "choco-stops (abandoned time)" and "vacant machine time"), the amount of tasks for the entire loom factory 2 can be known. This makes it easier to create work standards.

[0088] As described above, according to this embodiment, many looms (R01, etc.) (equipment) in the loom factory 2 can be operated efficiently with a small number of people. In addition, since the information in the loom operation status information storage unit 15 of the loom (R01, etc.) is displayed on the factory manager's PC 6, etc., the burden on the site supervisor such as the factory manager of the factory can be reduced.

[0089] Furthermore, since tasks are displayed on the mobile terminal 3, staff members can act autonomously, significantly reducing the burden of instructions given by site supervisors.

[0090] In the above-described embodiment, an example has been given in which the invention is realized as an apparatus, but the invention is not limited to this, and the invention may be distributed as a program that can be executed by a computer, stored on a storage medium such as a magnetic disk (e.g., a floppy (registered trademark) disk, a hard disk, etc.), an optical disk (e.g., a CD-ROM, a DVD), a magneto-optical disk (MO), or a semiconductor memory.

[0091] The storage medium may be any medium that can store a program and is computer readable. The storage format of the storage medium is not particularly limited.

[0092] In addition, an OS (operating system), database management software, network software, or other MW (middleware) running on a computer may execute some of the processes for realizing this embodiment based on instructions from a program installed on the computer from a storage medium.

[0093] Furthermore, the storage medium in the present invention is not limited to a medium independent of a computer, but also includes a storage medium that stores or temporarily stores a program downloaded via a LAN, the Internet, or the like.

[0094] Furthermore, the computer in the present invention only needs to execute each process in this embodiment based on a program stored in a storage medium, and may be a device consisting of a single personal computer, etc., or a system in which multiple devices are connected to a network.

[0095] In addition, the computer in this invention is not limited to a personal computer, but also includes an arithmetic processing device, a microcomputer, etc. included in information processing equipment, and is a general term for equipment or devices that can realize the functions of the present invention by a program.

[0096] The above describes the embodiments of the present invention. However, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the claims. The configurations of the above embodiments can be partially omitted or arbitrarily combined in a manner different from the above. [Explanation of symbols]
