The management system 800 is a management system in a certain facility and includes a machine tool 2, an IC card 3, a card reader 4, a server 1, and a smartphone 5. There may be a plurality of these devices.

(Machine tool 2)
The machine tool 2 is a device for processing a material, an intermediate product or the like, and is a device that consumes consumables and operates. An object to be processed by the machine tool 2 is called a work. The consumable item is, for example, cutting oil (coolant liquid), lubricating oil, or the like, which is necessary for operating the machine tool 2, or used to produce a higher quality product using the machine tool 2. It is an article.

The machine tool 2 may acquire its own operation data and send the operation data to the server 1. Here, the operation data is data including at least operation status information indicating an actual operation status of the machine tool 2. Specifically, the operation data is information on the date and time when the machine tool 2 machined a work, the machining time of one workpiece, the type of the workpiece to be machined, the machining record (production record) of the workpiece, the machine tool 2 Status information (for example, information indicating a state such as normal operation or whether any error has occurred) and the like. Since the machining program differs depending on the type of workpiece to be machined, the operation data may include the name of the machining program as information defining the “type of workpiece to be machined”.

When the machine tool 2 has a CNC (Computer Numerical Control) device that drives the components of the machine tool 2 such as a spindle and a tool rest by numerical control, the CNC device 6 of the machine tool 2 interfaces with the machine control unit 20. The (I/F) 22, the machine display unit 25, and the machine storage unit 26 may be included.

The machine control unit 20 executes various processes of the machine tool 2. The machine control unit 20 changes (updates) the machining program stored in the machine storage unit 26, for example. Each time the machine control unit 20 updates the machining program, the machine control unit 20 may notify the server 1 of information indicating the changed machining program (for example, the name of the machining program).

The machine storage unit 26 stores various data necessary for operating the machine tool 2. For example, the machine storage unit 26 stores a machining program for machining a work. The machining program is data that defines a method of machining a workpiece in the machine tool 2. Further, for example, the machine storage unit 26 also temporarily or non-temporarily stores the operation data of the machine tool 2.

The I/F 22 is a communication interface that controls communication between the machine tool 2 and other devices. The I/F 22 transmits the operation data stored in the machine storage unit 26 to the server 1 via the network 7 in response to a command from the machine control unit 20.

The machine display unit 25 is a display device that displays the operating status of the machine tool 2, measurement data, or the like.

(IC card 3)
The IC card 3 is a kind of device for recording the attendance of employees. In the present embodiment, a unique identifier (card ID) is assigned to each IC card 3, and each employee has one IC card 3 each. Thereby, the employee having the IC card 3 can be specified from the card ID. In other words, in this embodiment, the card ID is synonymous with the identifier of each employee. The IC card 3 includes an I/F 31, a card storage unit 32, and a card control unit 30.

The I/F 31 is a communication interface that controls communication between the IC card 3 and the card reader 4. The I/F 31 performs contact or non-contact communication with the card reader 4 to exchange information. The card storage unit 32 stores various data used in the IC card 3. For example, the card storage unit 32 stores a card ID.

The card control unit 30 centrally controls the IC card 3. For example, the card control unit 30 writes information to the card storage unit 32 or reads information from the card storage unit 32. When the I/F 31 establishes communication with the card reader 4, the card control unit 30 reads the card ID from the card storage unit 32 and sends it to the card reader 4 via the I/F 31.

(Card reader 4)
The card reader 4 is a kind of device for recording the attendance of employees and is a device for reading the information of the IC card 3. The card reader 4 includes a reader control unit 40, a detection unit 41, an I/F 43, a reader storage unit 45, and a reader timing unit 46.

The detection unit 41 is a communication interface that controls communication between the card reader 4 and the IC card 3. The detection unit 41 performs contact or non-contact communication with the I/F 31 of the IC card 3 and transmits/receives information. For example, when the detection unit 41 establishes communication with the IC card 3, the detection unit 41 authenticates the IC card 3 and receives the card ID of the IC card 3. The detection unit 41 sends the received card ID to the reader control unit 40.

The reader input unit 42 receives an input operation on the card reader 4. The reader input unit 42 is realized by a physical button or a touch sensor, for example. The reader display unit 44 is a display device that displays various types of information. The reader input unit 42 and the reader display unit 44 may be integrally configured as a touch panel.

The reader timing unit 46 measures time. The reader timing unit 46 measures the time when the detection unit 41 receives the card ID of the IC card 3, that is, the acquisition time of the card ID, and notifies the reader control unit 40.

The reader control unit 40 centrally controls the card reader 4. For example, the reader control unit 40 acquires the card ID read by the detection unit 41, and creates information in which the card ID is associated with the acquisition time of the card ID received from the reader timing unit 46. The reader control unit 40 transmits the information to the server 1 via the I/F 43 as a record of attendance time (attendance record) or a record of attendance time (attendance record).

The reader control unit 40 may determine whether the information in which the acquired card ID and the acquisition time of the card ID are associated with each other is the attendance record or the attendance record according to the acquisition time. For example, when the card ID acquisition time is in the morning, the reader control unit 40 may use the above-mentioned information including the card ID as the attendance record. Further, for example, when the card ID acquisition time is in the afternoon, the reader control unit 40 may use the above-mentioned information including the card ID as a work-out record. Alternatively, the reader control unit 40 may determine whether the information including the acquired card ID is the attendance record or the attendance record according to the input operation performed on the reader input unit 42.

Further, the reader control unit 40 may not associate the card ID read by the detection unit 41 with the acquisition time of the card ID. In this case, the reader control unit 40 transmits, for example, information including only the card ID, or information including the card ID and the division of attendance and leaving to the server 1. Then, the server control unit 10 (described later) of the server 1 associates the time measured by the server clock unit 13 (described later) with the card ID and records it in the attendance management DB 123 as a record of attendance or a record of attendance. As a result, the card ID and the acquisition time of the card ID in the server 1 are associated with each other and recorded in the attendance management DB 123. If the information transmitted by the card reader 4 does not include the above-mentioned classification of attendance or departure, the server control unit 10 records the card ID and the acquisition time according to the acquisition time of the card ID. It is also possible to decide whether to record as or as a leave record.

The I/F 43 is a communication interface that controls communication between the card reader 4 and the server 1. The I/F 43 transmits the information indicating the attendance record (attendance record information) or the information indicating the attendance record (attendance record information) acquired by the reader control unit 40 to the server 1 via the network 7.

The reader storage unit 45 stores various data used by the card reader 4. The reader storage unit 45 temporarily or non-temporarily stores the attendance record and the attendance record, for example.

The replenishment timing DB 122 is a DB that stores information related to replenishment or replacement of consumables in the machine tool 2. The replenishment timing DB 122 includes at least information indicating the replenishment timing of the machine tool 2.

The replenishment timing DB 122 is updated by the server control unit 10 every time the information on the item “scheduled machine stop time” in the machine operation DB 121 is updated. The replenishment timing DB 122 is updated each time the timing specifying unit 102, which will be described later, calculates the replenishment timing. Further, the replenishment timing DB 122 is updated every time the server control unit 10 receives a notification of exchange completion, which will be described later, from the smartphone 5.

FIG. 3 is a diagram showing an example of the data structure of the replenishment timing DB 122. As an example, FIG. 3 shows data of the replenishment timing DB 122 at 9:10 am on October 4, 2018. In the illustrated example, the replenishment timing DB 122 includes four items (four lines) of "machine tool ID", "previous replenishment time", "replenishment timing", and "necessity of replacement of consumables", and "machine tool ID". Is a data table in which information in other rows is associated with information in other rows.

The “machine tool ID” item stores the identifier of the machine tool 2. The item "previous replenishment time" stores information indicating the time when the consumable item was replenished last time. The information of the item is updated by the server control unit 10 when the notification of exchange completion is received from the smartphone 5. Information indicating the replenishment timing is stored in the item “replenishment timing”.

The item "Necessity of Consumables Replacement" stores information indicating the necessity of replacement of consumables on that day (October 4, 2018 in the illustrated example). If the date and time of the replenishment timing is before the scheduled machine stop time of each machine tool 2, it is necessary to replenish or replace consumables before the machine is stopped. Therefore, in this case, "necessary" is recorded in the item "necessity of replacement of consumables". On the other hand, when the date and time of the replenishment timing is after the scheduled machine stop time of each machine tool 2, it is not necessary to replenish or replace consumables before the machine is stopped. Therefore, in this case, "unnecessary" is recorded in the "necessity of consumables replacement" item.

The attendance management DB 123 includes, for example, seven items (7 lines) of “employee”, “attendance schedule”, “attendance record”, “attendance schedule”, “attendance record”, “next attendance schedule”, and “terminal identifier”. )including. The attendance management DB 123 is a data table in which the information of other employees is associated with the information of the "employee" row, and one row shows information about one employee.

The “employee” item stores an identifier of an employee whose attendance is managed by the management system 800.

In the item “scheduled attendance”, information indicating scheduled attendance date and time of each employee is stored. An employee whose item is “vacation” is a day off (October 4, 2018 in the illustrated example) which does not work all day. The “attendance record” item stores attendance records of each employee. Employees whose items are blank are not on the day of work.

The item “Scheduled to leave” stores information indicating the scheduled date and time of leaving each employee. An employee whose item is “vacation” is a day off (October 4, 2018 in the illustrated example) which does not work all day. The predetermined vacation, change of work time, and change of work time can be registered in advance by each employee by input operation to the card reader 4 or by using another system or another external device. The attendance management DB 123 is updated each time the registration is performed. The item of “record of leaving work” stores the leaving record of each employee. Employees whose items are blank are not on leave for the day.

The item “Scheduled to go to work next time” stores information indicating the date and time when each employee is scheduled to go to work next time. The information of the item is updated every time the attendance record is updated, based on a predetermined rule or a manned operation schedule recorded in the factory operation schedule DB 124.

Information indicating the identifier of the smartphone 5 owned by each employee is stored in the “terminal identifier” item. The identifier of the smartphone 5 may be, for example, a phone number, a mail address, a MAC address, a serial number, etc. of the smartphone 5.

(Plant operation schedule DB124)
FIG. 5 is a diagram showing an example of the data structure of the factory operation schedule DB 124. The factory operation schedule DB 124 is information indicating a daily schedule when the production line operates in a state where employees are present (a manned state). The factory operation schedule DB 124 stores at least the date and time and the date and time of the manned operation schedule at the date and time. In the illustrated example, the factory operation schedule DB 124 includes two items (two lines) of “date/time/shift” and “manned operation schedule”.

The item “date/time/shift” stores date and time and information indicating the type of factory shift at the date and time. The item “scheduled manned operation” stores information indicating a time zone in which the factory operates with employees (manned state) at each date and time. In addition, a blank section in the "Manned operation schedule" column indicates that the production line operates unmanned or the production line is completely stopped.

That is, when the production line does not operate unattended, the information in the factory operation schedule DB 124 is synonymous with the operation schedule of the production line. In this case, the information on the item “scheduled machine stop time” in the machine operation DB 121 described above may be obtained in consideration of the information on the item “planned manned operation” in the factory operation plan DB 124. Specifically, the machine stop scheduled time may be obtained on the assumption that the machine tool 2 is stopped during the time period other than the time period indicated by the item.

(Configuration of server control unit 10)
The server control unit 10 centrally controls the server 1. The server control unit 10 includes an information acquisition unit 101, a timing identification unit 102, a notification target person identification unit 103, and a notification instruction unit 104.

The information acquisition unit 101 acquires information necessary for various processes of the server control unit 10 from another device connected to the network 7 via the I/F 11. For example, the information acquisition unit 101 receives operation data from the machine tool 2. When the information acquisition unit 101 receives the operation data, the server control unit 10 updates the machine operation DB 121 of the server storage unit 12 according to the data. Further, for example, the information acquisition unit 101 receives the attendance record and the attendance record from the card reader 4. When the information acquisition unit 101 receives the attendance record and the attendance record, the server control unit 10 updates the attendance management DB 123 of the server storage unit 12 according to the data. Further, for example, the information acquisition unit 101 receives the exchange completion notification (described later) from the smartphone 5. When the information acquisition unit 101 receives the exchange completion notification, the server control unit 10 updates the replenishment timing DB 122 of the server storage unit 12.

The information acquisition unit 101 also acquires information necessary for various processes of the server control unit 10 from the server storage unit 12. For example, the information acquisition unit 101 acquires the machine operation DB 121 and the replenishment timing DB 122 from the server storage unit 12 and sends them to the timing identification unit 102. The information acquisition unit 101 also acquires the attendance management DB 123 from the server storage unit 12 and sends it to the notification target person identification unit 103.

The timing specifying unit 102 calculates the replenishment timing. The timing specifying unit 102 records the calculated replenishment timing in the replenishment timing DB 122 of the server storage unit 12.

In the present embodiment, the timing specifying unit 102 calculates the replenishment timing of all machine tools 2 once a day at a predetermined time before the operation start date and time of each day indicated by the factory operation schedule DB 124. I will. However, the calculation timing of the replenishment timing is not limited to this, and may be appropriately set according to the consumption speed of the consumables in the machine tool 2 and the like. For example, the timing specifying unit 102 may specify the replenishment timing at a predetermined time once a week. Further, the timing specifying unit 102 may calculate the replenishment timing by using some processing as a trigger. Specifically, the timing identifying unit 102 may calculate the replenishment timing at the timing when the machine operation DB 121 is updated. Further, the calculation timing of the replenishment timing may be different for each machine tool 2.

The timing specifying unit 102 calculates the replenishment timing based on the machine operation DB 121 acquired by the information acquisition unit 101, that is, using at least one of the operation schedule information and the operation status information that may be included in the machine operation DB 121. For example, based on the machining program executed by each machine tool 2, the consumption degree or consumption amount of consumables when machining one workpiece (that is, the consumption degree or consumption amount of consumables per workpiece) The timing specifying unit 102 estimates. Then, the timing specifying unit 102 calculates the replenishment timing when the workpiece is continuously processed from the estimated consumption degree or consumption amount. The timing specifying unit 102 records the calculated replenishment timing of each device in the replenishment timing DB 122.

Note that the consumption level or consumption amount of the consumable item per work may be determined in advance. For example, the degree of consumption or the amount of consumption of consumables per work of each machine tool 2 may be recorded in advance in the machine storage unit 26 or the machine operation DB 121 by an employee. When the consumption level or the consumption amount of the consumable item per work is recorded in the machine storage unit 26, the machine tool 2 transmits the consumption level or the consumption amount to the server 1 together with the operation data to the server control unit 10. The timing specifying unit 102 calculates the replenishment timing when the workpiece is continuously processed from the consumption degree or consumption amount received from the machine tool 2 or recorded in the machine operation DB 121.

In addition, when the production line does not operate unattended, the timing specifying unit 102 may calculate the replenishment timing in consideration of the information of the item “attended operation scheduled” in the factory operation schedule DB 124. Specifically, the replenishment timing may be calculated assuming that the consumables do not decrease because the machine tool 2 does not operate in the time zone other than the time zone indicated by the item.
The notification target person identification unit 103 identifies an employee (notification target person) to whom a notification is sent. Based on the attendance information, the notification target person identifying unit 103 predicts that among the employees of the manufacturing line, the employees who are expected to be working at the replenishment timing of the consumables necessary for the operation of each of the machine tools 2 included in the manufacturing line. Determine whether a member exists. Then, when there is an employee who is working, the employee is specified as the notification target person. It should be noted that the notification target person may be one person or plural persons. For example, the notification target person specifying unit 103 may set all the employees who are working as notification target people.

The notification target person specifying unit 103 also specifies the smartphone 5 of the specified notification target person. Specifically, the notification target person identification unit 103 reads a terminal identifier corresponding to the notification target person from the attendance information. The notification target person identification unit 103 notifies the notification instruction unit 104 of the terminal identifier.

Note that the notification target person specifying timing of the notification target person specifying unit 103 is not particularly limited as long as it is after the timing specifying unit 102 calculates the replenishment timing. For example, the notification target person specifying unit 103 may be determined according to the scheduled work time of each employee in today's attendance management DB 123 or according to the operation schedule for today in the factory operation schedule DB 124.

The notification instruction unit 104 transmits an output instruction of the consumption notification to the smartphone 5. The notification instructing unit 104 is notified by the notification target person specifying unit 103 of the terminal identifier of the smartphone 5 corresponding to the notification target person of each device. The notification instruction unit 104 transmits a consumption notification output instruction to the smartphone 5 having the specified terminal identifier when the time supplied from the server timing unit 13 reaches the specific time before the replenishment timing of each device. In addition, when the smartphone 5 receives the consumption notification output instruction from the server 1, it is desirable to output the consumption notification without delay. As a result, the smartphone 5 owned by the notification subject can be made to output the consumption notification at the specific time.

The content of the output instruction transmitted by the notification instruction unit 104 is not particularly limited. For example, the output instruction may include an image, text data, voice data, or the like to be output as the consumption notification. Further, the output instruction may include the identifier or name of the device when the replenishment timing comes. Further, the output instruction may be a simple instruction command for the smartphone 5.

It should be noted that the notification instruction unit 104 may transmit the output instruction to the smartphone 5 having the terminal identifier when the notification target person identification unit 103 notifies the notification target person of the terminal identifier. In other words, the notification instruction unit 104 may send the output instruction to the smartphone 5 without waiting until the specific time arrives. In this case, the output instruction includes information indicating the specific time. The smartphone 5 measures the time with the timekeeping section of its own device and outputs a consumption notification when the specific time comes. In this case, the server clock 13 is not essential in the server 1.

Further, the method of determining the specific time described above is not particularly limited. For example, the specific time may be predetermined for each device, or may be determined by referring to the replenishment timing of the replenishment timing DB 122 every time the notification instruction unit 104 is notified of the terminal identifier. Further, the specific time may be determined by calculating backward from the replenishment timing for each device. In the present embodiment, the notification instruction unit 104 determines that one hour before the replenishment timing is the output time of the consumption notification.

(Smartphone 5)
The smartphone 5 is a terminal device carried by each employee. The smartphone 5 includes a terminal control unit 50, a terminal input unit (input unit) 51, an I/F (reception unit, transmission unit) 52, a terminal storage unit 53, and a terminal display unit (output unit) 54. Including.

The terminal input unit 51 is an input device for receiving an input operation of the user of the smartphone 5. The terminal display unit 54 is a display device that displays various types of information. The terminal input unit 51 and the terminal display unit 54 may be integrally configured. In the present embodiment, the smartphone 5 is assumed to include a touch panel in which the terminal input unit 51 and the terminal display unit 54 are integrally configured.

The I/F 52 is a communication interface that controls communication between the smartphone 5 and the server 1. The I/F 52 receives the notification information from the server 1 via the network 7 and sends it to the terminal control unit 50.

The terminal storage unit 53 stores various data used by the smartphone 5. The terminal storage unit 53 also stores a terminal identifier that is a unique identifier of each smartphone 5. The terminal storage unit 53 may store the employee identifier associated with the smartphone 5.

The terminal control unit 50 comprehensively controls the smartphone 5. The terminal control unit 50 causes the terminal display unit 54 to output (display) the consumption notification based on the output instruction received from the server 1. When the terminal control unit 50 receives the output instruction, it is desirable to output the consumption notification without delay.

However, when the output instruction includes information indicating the specific time, that is, when the server 1 does not monitor whether or not the specific time comes, the consumption notification is not output immediately, but
The terminal control unit 50 monitors whether or not the specific time has come, and outputs a consumption notification when the specific time comes.

Further, when the input unit accepts a predetermined input operation, the terminal control unit 50 transmits an exchange completion notification indicating that the consumable item has been replenished or exchanged to the server 1 via the I/F 52.

<<Processing flow of server 1>>
FIG. 6 is a flowchart showing an example of the flow of processing when the server 1 specifies a notification target person of a wear notification for a machine tool 2 and causes the smartphone 5 to output the wear notification.

The information acquisition unit 101 of the server 1 acquires at least one of the operation schedule information and the operation status information from the machine operation DB 121 of the server storage unit 12 (S300). The information acquisition unit 101 sends the acquired information to the timing identification unit 102.

The timing specifying unit 102 calculates the replenishment timing based on at least one of the operation schedule information and the operation status information (S301). The timing specifying unit 102 records the replenishment timing of each machine tool 2 in the replenishment timing DB 122. The processing from S300 to S301 is executed once a day for all machine tools 2 at a predetermined time. Subsequent processing may be executed at different timings for each machine tool 2, or may be executed at the same timing.

The information acquisition unit 101 acquires the attendance information of the employee from the attendance management DB 123 (S302). The notification target person identifying unit 103 determines, based on the attendance information, whether or not there is an employee at work at the replenishment timing transmitted from the timing identifying unit 102 (S303). For example, the notification target person identifying unit 103 regards an employee whose scheduled work time or work time is a time before the replenishment timing and whose scheduled work time is a time after the replenishment timing as “work at the time of the replenishment timing. Medium employee”.

When there is an employee who is working (YES in S303), the notification target person identification unit 103 identifies the employee who is working as a notification target person (S304). The number of notified persons may be one or plural. Next, the notification target person identification unit 103 identifies the smartphone 5 of the notification target person who has been identified by referring to the attendance information (S305). The notification target person identification unit 103 notifies the notification instruction unit 104 of the terminal identifier.

When notified of the terminal identifier, the notification instruction unit 104 waits until the time (that is, the current time) supplied from the server timing unit 13 reaches the specific time (that is, one hour before the replenishment timing) (NO in S306). ). When the specific time has come (YES in S306), the notification instruction unit 104 transmits an output instruction of the consumption notification to the notification target person's smartphone 5 (S307).

In addition, when the employee who is working does not exist (it is NO at S303), the notification target person identification part 103 may identify another employee or manager as a notification target person (S308). The person to be notified in this case may be determined regardless of whether he is working or not. Even if another employee or manager is specified as the notification target person, the processing after S305 is the same.

According to the above processing, the consumption notice is output before the replenishment timing to the employees who are expected to be working at the replenishment timing of the machine tool 2, that is, the consumables can be exchanged or replenished. can do. Therefore, an appropriate person can be urged to replenish or replace consumables used for operating the machine tool 2.

(Specific example of consumption notification)
FIG. 7 is a diagram illustrating an example of the consumption notification displayed on the terminal display unit 54 of the smartphone 5. The consumption notification includes, for example, information L1 that prompts replenishment, information L2 that indicates the work schedule of the employee who owns the smartphone 5, machine tool 2 that should replace the consumable item, and information L3 that indicates the replenishment deadline. .. Further, the terminal display unit 54 may display a replenishment button B1 for notifying the server 1 that the consumable item has been replenished or replaced, as well as the consumption notification.

When the employee executes an input operation of pressing the replenishment button B1, the terminal control unit 50 receives the input operation. When the terminal control unit 50 receives the input operation, the terminal control unit 50 transmits an exchange completion notification indicating that the consumable item has been replenished or exchanged to the server 1 via the I/F 52. As a result, it is possible to notify the information processing apparatus that the employee has confirmed the notification and that the consumable item has been replenished or replaced. By pressing the replenishment button B1, the “previous replenishment time” in the replenishment timing DB 122 is updated.

It should be noted that the consumption notification may be output not only by screen display, but also by combining various output means that the smartphone 5 may have, such as voice, light, and vibration.

[Embodiment 2]
Another embodiment of the present invention will be described below. For convenience of description, members having the same functions as the members described in the above embodiment will be designated by the same reference numerals, and the description thereof will not be repeated.

<<Main configuration of management system 900>>
FIG. 8 is a diagram showing an outline of the management system 900 according to the second embodiment and a main configuration of each device. The management system 900 differs from the management system 800 according to the first embodiment in that the server storage unit 12 of the server 1 includes a person-in-charge DB 125 and that the server control unit 10 includes a device-in-charge identifying unit 105. In addition to the function of the information acquisition unit 101, the information acquisition unit (person in charge information acquisition unit) 106 in the management system 900 has a function of acquiring the person DB 125 from the server storage unit 12 and sending it to the equipment specifying unit 105. ..

(DB125 in charge)
FIG. 9 is a diagram showing an example of the data structure of the person-in-charge DB 125. The person-in-charge DB 125 is a DB of information (person-in-charge information) indicating persons in charge of each machine tool 2 on the manufacturing line. The person-in-charge DB 125 is data defined in advance and stored in the server storage unit 12. In the illustrated example, one column of the person-in-charge DB 125 shows the person-in-charge information for one machine tool 2.

In the illustrated example, the person-in-charge DB 125 includes three items (3 lines) of “machine tool ID”, “main charge”, and “sub charge”, and the information of the “machine tool ID” line indicates another line. 2 is a data table in which the information of (1) is associated.

The “machine tool ID” item stores the identifier of the machine tool 2. The "main charge" and "sub charge" items store the identifiers of the employees who are the main charge and the sub charge of each machine tool 2, respectively. Here, the term “mainly in charge” refers to an employee who gives priority to the operation and management of the machine tool 2. On the other hand, the sub-charge indicates an employee who prioritizes the operation and management of the machine tool 2 after the main charge. In other words, it can be said that the items “main charge” and “sub charge” in the contact information indicate the priority of each contact.

In addition, the card ID of the IC card 3 associated with the employees who are the main charge and the sub charge of the machine tool 2 may be stored in the items of the “main charge” and the “sub charge”, respectively. If each employee is associated with the smartphone 5 on a one-to-one basis, the items “main charge” and “sub charge” are assigned to the employee who is the main charge and the sub charge of the machine tool 2, respectively. The terminal identifier of the associated smartphone 5 may be stored.

Further, one employee may be the main charge and the sub-charge of a plurality of machine tools 2. Further, three or more persons in charge may be set for one machine tool 2. In that case, it is preferable that the priority of each person in charge is set. For example, the person with the highest priority is set as the main person, the person with the second highest priority is the sub-person, the person with the third highest priority is the worker, and the three persons are It may be set in the person-in-charge DB 125. In addition, an administrator who manages the plurality of machine tools 2 may be set separately from the person in charge.

(Device identification unit 105)
The in-charge device identification unit 105 identifies the machine tool 2 (in-charge device) to which each employee is in charge (main charge or sub charge) based on the charge information in the charge DB 125. The assigned device identification unit 105 notifies the notification target person identification unit 103 of the identified person.

<<Processing flow of server 1>>
FIG. 10 is a flowchart showing an example of the flow of processing when the server 1 according to the present embodiment identifies the notification target person of the wear notification regarding the machine tool 2 and causes the smartphone 5 to output the wear notification. Note that the processes of S350 to S353 of FIG. 10 are the same as the processes of S300 to S303 of FIG. 6, and thus the description thereof will not be repeated.

When there is an employee who is predicted to be working at the time of the replenishment timing (YES in S353), the notification target person identification unit 103 causes the assigned device identification unit 105 to identify the machine tool 2 of the employees who are working. Instruct them to confirm that the person in charge is included. The in-charge device identification unit 105 refers to the in-charge information about the employee who is working from the person-in-charge DB 125 (S354), and determines whether the employee who is working includes the person in charge of the machine tool 2. (S355 and S360). At this time, the assigned device identification unit 105 first determines whether or not the main employee in charge of the machine tool 2 is included in the employees who are working (S355).

When the employee who is working includes the main person in charge (YES in S355), the in-charge device identification unit 105 sends information identifying the main person in charge to the notification target person identification unit 103. Upon being notified of the main person in charge by the device-in-charge identifying section 105, the notification target person identification unit 103 identifies the main person in charge as the notification target person (S356).

On the other hand, when the employee who is working does not include the main person in charge (NO in S355), the device identifying unit 105 in charge determines whether the employee who is working includes the subperson in charge (S360). .. When the sub-charge is included (YES in S360), the assigned device identification unit 105 sends information identifying the sub-assignment to the notification target person identification unit 103. The notification target person specifying unit 103, upon being notified of the sub charge by the assigned device specifying unit 105, specifies the sub charge person as the notification target person (S361). The processing after the notification target person specifying unit 103 specifies the notification target person, that is, the processing of S357 to S359 is the same as the processing of S305 to S307 of FIG.

If there is an employee who is working, but is neither the primary person in charge nor the sub-person (NO in S355 and S360), or if there is no employee in duty (NO in S353), the person to be notified The identifying unit 103 may identify another employee or manager as a notification target person (S362). Even when another employee or manager is specified as the notification target person, the processing after S357 is the same.

In addition, when the notification target is another employee or manager who is working, the notification instruction unit 104 may transmit the output instruction to the smartphone 5 multiple times. That is, the consumption notification may be output multiple times on the smartphone 5. It is difficult for other employees or managers to recognize that the consumables need to be replenished or replaced because they are different from the original responsibility of the machine tool 2. In such a case, by outputting the consumption notification from the smartphone 5 a plurality of times, it is possible to more strongly urge the supply or replacement of the consumable item.

According to the above processing, regarding the machine tools 2 included in the production line, the person in charge (main person or sub person) of each machine tool 2 is working, that is, it is possible to replace or replenish consumables. If predicted, a notification can be output to the person in charge. Therefore, it is possible to urge more appropriate personnel to replenish or replace consumables for each device on the manufacturing line.

Further, according to the above-described processing, the notification is output to the main person in charge, that is, the person having the highest priority among the persons in duty at the replenishment timing for each device. As a result, for each machine tool 2 on the manufacturing line, it is possible to encourage more appropriate personnel to replenish or replace consumables.

[Embodiment 3]
In the management system 900, when the attendance record of an employee is updated, the notification target person identification unit 103 of the server 1 has replenished the equipment in charge of the employee before the scheduled date and time for the employee to leave. In this case, the employee may be specified as the notification target person for the device in charge. The third embodiment of the present invention will be described below.

FIG. 11 is a sequence diagram showing a flow of processing executed by the card reader 4 and the server 1 according to this embodiment. In the following examples, unless otherwise stated, the card reader 4 determines whether the employee having the card ID read from the IC card 3 has gone to work or has left the office, depending on the time of day when the card reader 4 communicated with the IC card 3. Will be determined.

When the detection unit 41 of the card reader 4 detects that the IC card 3 has been touched (approximated or contacted) in a predetermined time period (YES in S400), the reader control unit 40 of the card reader 4 causes the IC card 3 to operate. The card ID is received from and the attendance record of the employee corresponding to the card ID is created. The reader control unit 40 transmits attendance record information to the server 1 (S401). The information acquisition unit 106 of the server 1 receives the attendance record information (S402). The information acquisition unit 106 updates the attendance record of the employee indicated by the information in the attendance management DB 123 based on the received attendance record information (S403).

When the attendance record is updated, the assigned device identification unit 105 identifies the assigned device of the employee (attendance employee) whose attendance record is updated. Then, the notification target person identifying unit 103 reads out the replenishment timing of the equipment in charge of the attending employee and the attendance information of the attending employee, which are recorded in the replenishment timing DB 122. The notification target person identifying unit 103 determines whether or not the replenishment timing is before today's scheduled departure time of the attending employee (S404). When the replenishment timing is before today's scheduled departure time of the attending employee (YES in S404), the notification target person identifying unit 103 identifies the attending employee as the notification target person. Then, the notification instruction unit 104 specifies the smartphone 5 of the notification target person (S405), and when the specific time comes (YES in S406), transmits an output instruction to the smartphone 5 (S407). The processing contents of S405 to S407 are the same as the processing contents of S305 to S307 of FIG.

According to the above processing, it is possible to specify whether or not the employee is the notification target person, triggered by the fact that the person in charge of each device actually goes to work. Then, when the employee is the notification target person, a consumption notification is output to the employee at a specific time. As a result, it is possible to reliably output the notification to the employees who are at work.

[Embodiment 4]
In the management system 900, the notification target person specifying unit (absentee specifying unit) 103 of the server control unit 10 specifies an employee whose attendance time record is not updated even after the scheduled attendance time as an absentee. Good. Further, the assigned device identification unit 105 may identify the machine tool 2 that is the assigned device of the absentee based on the information about the assigned person. Then, when the replenishment timing of the machine tool 2 which is the device in charge of the absentee is before the scheduled departure date and time of the absentee, the notification target person identifying unit 103 assigns other employees other than the absentee to the machine tool 2 May be specified as the notification target person. The “scheduled leave date/time of the absentee” is the scheduled leave date/time when the absentee has been working according to the scheduled attendance date/time. Specifically, the "scheduled leave time of the absentee" is the date and time indicated by the "Scheduled leave" item in the attendance management DB 123 of the absentee. Further, the “absent person” in the present embodiment is used to refer to an employee who has not come to work even after the attendance time as described above, and for example, a late person who has come to work one hour after the attendance time. Also, until the attendance, for convenience sake, it will be treated as "absent person".

(Process flow)
FIG. 12 is a flowchart showing an example of the flow of processing executed by the server 1 according to this embodiment. Whether the notification target person identification unit 103 of the server control unit 10 updates the attendance record of each employee by the time (scheduled attendance time) indicated by the scheduled attendance date and time stored in the attendance management DB 123 for each employee. It is monitored whether or not (S500). For the employee whose attendance record has been updated by the scheduled attendance time (YES in S500), the notification target person identifying unit 103 executes the processes described in the first to third embodiments, and thus the special process described in the present embodiment is performed. Not performed. On the other hand, regarding the employee whose attendance record has not been updated by the scheduled attendance time (NO in S500), the notification target person identifying unit 103 determines that the employee is absent (S501). When an absentee occurs, the assigned device identification unit 105 identifies the assigned device of the absentee. Then, the notification target person identification unit 103 determines whether or not the device replenishment timing of the device in charge of the absentee is before today's scheduled leave time of the absentee, which is indicated by the attendance management DB 123 (S502). ..

When the replenishment timing of the absentee's device in charge is not before the today's scheduled departure time of the absentee (NO in S502), it is predicted that the absentee's absence will not be affected. In this case, the notification target person identification unit 103 does not perform any particular process. On the other hand, when the replenishment timing of the device in charge of the absentee is before the scheduled time when the absentee leaves work today (YES in S502), the in-charge device identifying unit 105 identifies the sub-assignee of the device and identifies the notification target person. Report to section 103. The notification target person identifying unit 103 reads the attendance management DB 123 and refers to the attendance information of the sub-person in charge (S503).

From the attendance information, the notification target person identifying unit 103 determines whether or not the deputy person is working at the time of the replenishment timing (S504). When the sub-charger is working at the time of the replenishment timing (YES in S504), the notification target person identification unit 103 specifies the sub-charger as the notification target person (S505). On the other hand, when the deputy person is not working at the time of replenishment timing (NO in S504), the notification target person specifying unit 103 specifies another employee or manager who is working as a notification target person (S509).

Then, the notification instruction unit 104 identifies the notification target person's smartphone 5 (S506), and when the specified time comes (YES in S507), transmits an output instruction to the smartphone 5 (S508). The processing contents of S506 to S508 are the same as the processing contents of S305 to S307 of FIG.

Note that when another employee or manager who is working at S509 is the notification target person, the notification instruction unit 104 may transmit the output instruction to the smartphone 5 multiple times. That is, the consumption notification may be output multiple times on the smartphone 5. It is difficult for other employees or managers to recognize that the consumables need to be replenished or replaced because they are different from the original responsibility of the machine tool 2. In such a case, by outputting the consumption notification from the smartphone 5 a plurality of times, it is possible to more strongly urge the supply or replacement of the consumable item.

According to the above configuration, when the timing of the device in charge comes while the employee is absent, a notification prompting supplementation or replacement of consumables is output to the terminal device of the sub-person or another employee. Accordingly, even when an employee is absent, it is possible to inform other employees who are working that the consumables of the equipment of the absentee should be replenished or replaced.

It should be noted that even for an employee who has come to work after the scheduled work date and time, that is, a late person who is unexpectedly late, the above-mentioned processing for the absentee may be performed when the scheduled work date and time has passed. In this case, if the late person comes to work before the specific time (or the timing at which the server 1 sends the output instruction to the smartphone 5), the consumption notification is triggered by recording the attendance record in the attendance management DB 123. (In other words, the notification target person may be changed so as to be transmitted to the original person in charge of the machine tool 2). For example, when the late person comes to work later, the series of processes shown in FIG. 10 of the third embodiment may be executed. As a result, when the timing of replenishing the device in charge arrives before the scheduled departure time of the late person, the smartphone 5 of the late person can output the consumption notification.

[Embodiment 5]
In the management system 900, the notification target person identifying unit 103 of the server control unit 10 determines that when the employee's leaving record is updated, the timing of replenishment of the equipment in charge of the employee is the next scheduled attendance of the employee. If it is before the date and time, another employee who is working may be specified as the notification target person of the device in charge.

(Process flow)
FIG. 13 is a sequence diagram showing a flow of processing executed by the card reader 4 and the server 1 according to this embodiment. When the detection unit 41 of the card reader 4 detects that the IC card 3 is touched (approximated or contacted) in a predetermined time period (YES in S600), the reader control unit 40 of the card reader 4 reads the card from the IC card 3. The ID is received, and a leave record of the employee corresponding to the card ID is created. The reader control unit 40 transmits information indicating the record of leaving work (leave record information) to the server 1 (S601). The information acquisition unit 106 of the server 1 receives the leaving record information (S602). The information acquisition unit 106 updates the attendance record of the employee indicated by the information in the attendance management DB 123 based on the received attendance record information (S603).

When the attendance record is updated, the assigned device identification unit 105 identifies the assigned device of the employee (leaved employee) whose attendance record is updated. Then, the notification target person specifying unit 103 reads out the replenishment timing of the device in charge of the retired employee and the attendance information of the retired employee, which are recorded in the replenishment timing DB 122. The notification target person identifying unit 103 determines whether or not the replenishment timing is before the next scheduled attendance date/time of the leaving employee (S604).

When the replenishment timing is after the scheduled departure date and time of the leaving employee (NO in S604), the server 1 does not execute the process described below. This is because if the replenishment timing is after the scheduled departure date and time of the retired employee, it is sufficient to output the consumption notification after the next attendance at work. On the other hand, when the replenishment timing is before today's scheduled departure time of the retired employee (YES in S604), the notification target person identification unit 103 determines that the factory operation schedule of the factory operation schedule DB 124 and each employee of the attendance management DB 123 are included. The attendance information is referred to (S605). The notification target person identifying unit 103 further determines whether or not the replenishment timing of the device in charge of the leaving employee is before another employee's scheduled attendance (S606). When the timing of replenishment of the device in charge of the leaving employee is before the attendance schedule of another employee (YES in S606), the notification target person identifying unit 103 identifies the leaving employee as the notification target person, and the leaving employee. The terminal identifier of the smartphone 5 is transmitted to the notification instruction unit 104.

Then, the notification instruction unit 104 immediately transmits the immediate notification output instruction to the smartphone 5 of the leaving employee (S607). Here, the immediate notification is a type of notification that prompts replenishment or replacement of consumables. Further, “immediately” means that the output instruction is transmitted to the smartphone 5 without delay as soon as it is created, without waiting until a specific time arrives as in the first embodiment. Upon receiving the output instruction from the notification instruction unit 104, the terminal control unit 50 of the smartphone 5 outputs an immediate notification from the terminal display unit 54.

(Example of immediate notification output)
FIG. 14 is a diagram illustrating an example of the immediate notification displayed on the terminal display unit 54 of the smartphone 5. The immediate notification includes, for example, information L4 that prompts replenishment, information L5 that indicates the machine tool 2 whose consumable item should be replaced, and the replenishment deadline. Note that the information L4 that prompts replenishment may be the same as or different from L1 in FIG. Further, the replenishment button B1 may be displayed on the terminal display unit 54 together with the consumption notification. The function of the supplement button B1 is the same as the function of the supplement button B1 in the consumption notification according to the first embodiment.

On the other hand, when the replenishment timing of the device in charge of the leaving employee is not before the attendance schedule of another employee (NO in S606), that is, it can be predicted that the other employee is in attendance at the replenishment timing of the device in charge. In this case, the notification target person specifying unit 103 specifies an employee other than the leaving employee as a notification target person (S608). In this case, the notification instruction unit 104 does not send the output instruction of the immediate notification, but sends the normal output instruction of the consumption notification. Specifically, the notification target person identifying unit 103 and the notification instructing unit 104 perform the same processing as S305 to S307 in FIG. 6 of the first embodiment as S609 to S611.

According to the above process, when the replenishment timing for the device in charge of a certain employee arrives from the time when the employee leaves work to the next scheduled work time, another employee who is predicted to be working during that time Members can be the notification target. Thus, even when the timing comes after the person in charge of a certain device has already left the office, other employees who are working can be informed that the consumables of the device should be replenished or replaced.

Further, according to the above processing, when the employee arrives at the timing of the device in charge while no other employee is working, the employee immediately outputs an immediate notification from his/her terminal device. It As a result, it is possible to prevent the operation of the device from being stopped due to exhaustion of consumables during the period when no one is present.

Note that the processing from S604 onward in FIG. 13 may be performed not at the time when the employee's leaving record is updated, but at a predetermined time (for example, one hour) before the scheduled leaving time of each employee. As a result, each employee can replenish or replace the consumables of his/her own equipment while working.

Even if the replenishment timing is after the scheduled departure date and time of the retired employee (NO in S604), the notification-targeted person identification unit 103 determines whether the replenishment timing is from the next scheduled attendance date and time to the replenishment timing time. If the time is within the predetermined time, the processing of S605 and S606 or S608 may be executed as in the case of YES in S604. Then, the notification instruction unit 104 may cause the smartphone 5 to output an immediate notification by executing the process of S607. Thus, when the replenishment timing comes within a predetermined time (for example, 5 minutes or the like, which is an extremely short time) from the employee's attendance, it is possible to notify in advance at the time of leaving before that time. As a result, it is possible to prevent replenishment leakage or replacement leakage of consumables.

[Sixth Embodiment]
In the management system 900, the notification instruction unit 104 of the server control unit 10 transmits an immediate notification output instruction to the notification target person when the output time (specific time) of the consumption notification is before the attendance time of the notification target person. You may.

(Process flow)
FIG. 15 is a sequence diagram showing a flow of processing executed by the card reader 4 and the server 1 according to this embodiment. Note that the processing of S700 to S703 in the figure is the same as the processing of S400 to S403 in the third embodiment, and thus the description thereof will not be repeated.

When the attendance record is updated, the assigned device identification unit 105 identifies the assigned device of the attending employee. Then, the notification target person identification unit 103 determines whether or not the attendance time of the attending employee is after the output time (that is, the specified time) of the consumption notification of the device in charge (S704). When the attendance time of the attending employee is after the output time of the consumption notification of the device in charge (YES in S704), the notification target person identifying unit 103 identifies the attending employee as the notification target person. Then, the notification instruction unit 104 immediately transmits an immediate notification output instruction to the smartphone 5 of the leaving employee (S705).

On the other hand, when the attendance time of the attending employee is before the output time of the consumption notification of the device in charge (NO in S704), the notification instruction unit 104 does not issue the output instruction of the immediate notification, and the server 1 ends the process. ..

According to the above process, if the specific time has passed when the employee comes to work, the smartphone 5 can immediately output the notification. Thereby, even when there is no time from the time of work to the time when the consumable supplies should be replenished or replaced, the employee can be surely notified that the consumable supplies need to be replenished or replaced.

[Modification]
<<Remaining Consumables Detection>>
The machine tool 2 of the management system 800 or the management system 900 may measure the remaining amount of the consumable item of the machine tool 2 using a sensor such as a float sensor and send the measured remaining amount to the server 1. Then, the timing specifying unit 102 of the server 1 may specify the replenishment timing when the remaining amount of the consumable item detected by the sensor is equal to or less than the first predetermined amount. As a result, the replenishment timing is specified according to the actual remaining amount of the consumable item, so that the employee can be prompted to replenish or replace the consumable item at a more appropriate timing.

≪Modification of replenishment button≫
The server 1 related to the management system 800 and the management system 900 may receive the exchange completion notification from the machine tool 2 instead of the smartphone 5. Specifically, when the remaining amount of the consumable item is measured by the sensor such as the float sensor in the machine tool 2, the machine control unit 20 determines that the remaining amount of the consumable item measured by the sensor is equal to or more than the second predetermined amount. In such a case, it may be determined that the consumable item has been replenished or replaced, and the replacement completion notification may be transmitted to the server 1.

In this case, transmission of the exchange completion notification from the smartphone 5 to the server 1 is not essential. Therefore, when the consumption notification or the immediate notification is displayed on the terminal display unit 54, the display of the supplement button B1 shown in FIGS. 7 and 14 is not essential.

In addition, when the consumable item of the machine tool 2 is lubricating oil, a sensor for detecting that the lubricating oil has fallen below a first predetermined amount and a sensor for detecting that the lubricating oil has been replenished up to a second predetermined amount or more. Both may be provided in the machine tool 2.

≪Process sharing in each device≫
The smartphone 5 in the management system 800 or the management system 900 may also have a function as the IC card 3. For example, contactless communication of the smartphone 5 or the like may be used to perform communication between the smartphone 5 and the card reader 4 when the smartphone 5 is brought close to the detection unit 41 of the card reader 4. Then, by the communication, the employee identifier or the terminal identifier stored in the terminal storage unit 53 of the smartphone 5 may be transmitted from the smartphone 5 to the card reader 4. In this case, the IC card 3 is not essential in the management system 800.

The calculation of the replenishment timing may be performed by the machine tool 2 instead of the server 1. In this case, the machine operation DB 121 and the machining program 122 are stored in the machine storage unit 26, and the machine control unit 20 of the machine tool 2 has the function of the timing specifying unit 102.

Further, the server 1 in the management system 800 or the management system 900 is a database server having the server storage unit 12, and the information acquisition unit 101 or 106 of the terminal control unit 50, the timing identification unit 102, the device identification unit 105 in charge, and the notification target person. The processes of the identifying unit 103 and the notification instructing unit 104 may all be executed by the terminal control unit 50 of the smartphone 5. In this case, the smartphone 5 of each employee calculates the replenishment timing of the machine tool 2 handled by the owner of the own terminal at a specific timing, and determines whether the owner is the notification target person. Then, when the owner is the notification target person, the notification setting information is created in the own device and the notification setting is executed.

Further, in the management system 800 or the management system 900, the device for recording the attendance of the employee is not limited to the IC card 3 and the card reader 4 described above. For example, without using the IC card 3, biometric information authentication of each employee such as face authentication or fingerprint authentication is performed by an authentication device to identify each employee, and the time at the time of identification is set to the work time or the work leave. It may be the time. In addition, the management system 800 or the management system 900 is an apparatus for recording attendance of employees, and is an operating state of the smartphone 5, position information received by a GPS receiver included in the smartphone 5, or a signal such as a beacon. May be included in the receiver. Then, the position of each employee is specified from the data received by the receiver, and depending on the position (for example, whether or not the employee is near the manufacturing line), the employee's attendance and leaving work. May be specified.

Further, the management system 800 or the management system 900 may include, instead of the smartphone 5, a device (small programmable display device or the like) that has an output means and that can be carried by an employee. In this case, the device outputs a consumption notification or an immediate notification instead of the smartphone 5.

A program (machining program) for operating each of the machine tools 2 constituting the equipment is stored in the storage unit in each device, but the program may be stored in the server storage unit 12 of the server 1. .. In this case, a plurality of programs of a plurality of devices are stored in the server storage unit 12, and the programs necessary for the work processing from the server 1 to each device are stored according to the type of the work processed by the equipment. And the program is stored in each device.
