DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiments and modifications. Various modifications other than the following embodiments and modifications are possible according to the design, etc., as long as they do not deviate from the technical idea of ​​the present disclosure.

[0013] (Embodiment) Hereinafter, a tool system, a processing method, a program, and a tool device according to the present embodiment will be described with reference to FIGS. 1 to 6. FIG.

[0014] (1) Overview Fig. 1 is a schematic block diagram of a tool system 3 according to the present embodiment. Fig. 2 is a schematic system configuration diagram of the tool system 3 according to the present embodiment.

[0015] A tool system 3 of the present embodiment includes a tool device 1 and an information management device 2, as shown in FIGS.

[0016] As shown in FIG. 1 and FIG. 3, the tool device 1 is a tool for business operators to be used in, for example, a factory or a construction site. As shown in FIG. 1, the tool device 1 has a tool unit 13, an acquisition unit 19, and a transmission unit 15. The tool unit 13 is driven by a power source and performs a specific operation OP100 (see FIG. 6) on a work object. The specific operation OP100 corresponds to, for example, performing an operation of fastening a work object (such as a steel plate) to a fastening member with a plurality of fastening members (such as screws and bolts) according to a design drawing or a work instruction manual. The tool device 1 is, for example, an electric impact driver that fastens by rotating the fastening members to apply an impact force. Note that the tool device 1 is not limited to an electric impact driver, and may be an electric impact wrench, or may be an electric drill driver or an electric torque wrench that does not apply an impact force. Also, the tool device 1 is not limited to an electric tool, and may be, for example, an air tool driven by compressed air (such as a driver or a nail driver).

[0017] The acquisition unit 19 acquires the work information D1 including information for identifying the work interval time T5 (see FIG. 6) between a first work OP1 (see FIG. 6) included in the specific work OP100 and a second work OP2 (see FIG. 6) that follows the first work OP1 and is included in the specific work OP100. In this embodiment, the first work OP1 and the second work OP2 are included in the specific work OP100 and have the same work content (for example, tightening a screw). However, the first work OP1 and the second work OP2 may have different work content, for example, the first work OP1 may be tightening a screw and the second work OP2 may be loosening a screw.

[0018] The transmission unit 15 transmits the work information D1 to the information management device 2. In this embodiment, the transmission unit 15 is used, but is not limited to this configuration. The tool device 1 may also include a communication unit capable of mutual communication with the information management device 2.

[0019] As shown in FIG. 1, the information management device 2 has a receiving unit 22 that receives the work information D1 from the tool device 1. In this embodiment, the work information D1 includes information for identifying the work interval time T5. Specifically, the work information D1 is information corresponding to each of a plurality of individual tasks (first task OP1, second task OP2) included in a specific task OP100 (see FIG. 6), and includes at least one of the time when the worker started the work in the corresponding individual task and the fastening torque value in the corresponding task. In this embodiment, the work information D1 is information corresponding to each of a plurality of individual tasks included in a specific task OP100, and includes both the time when the worker started the work in the corresponding individual task and the fastening torque value in the corresponding task. For example, the work information D1 corresponding to the first task OP1 includes the time when the worker started the work in the first task OP1 and the fastening torque value in the first task OP1. The work information D1 corresponding to the second task OP2 includes the time when the worker started the work in the second task and the fastening torque value in the second task. Here, the pass / fail judgment result will be described. 1, the tool device 1 has a measuring unit 14. The measuring unit 14 measures a tightening torque value and stores it in a memory unit 16 of the tool device 1. The tool device 1 also includes the tightening torque value in work information D1 and transmits it from the transmitting unit 15 to the information management device 2. In this embodiment, the information management device 2 has a judging unit 215. The judging unit 215 judges whether the tightening work is good or bad based on the tightening torque value received by the receiving unit 22. The pass / fail judgment result includes, for example, a judgment result on the pass / fail of the tightening work.

[0020] The information management device 2 has a display unit 23 that displays at least one of the task interval time T5 based on the task information D1 and attribute information related to the worker based on the task information D1. The display unit 23 may display the task interval time T5 or may display the attribute information related to the worker. Alternatively, the display unit 23 may display both the task interval time T5 and the attribute information related to the worker. Here, the attribute information of the worker is, for example, information related to the proficiency of the worker inferred from the task interval time T5. If the task interval time T5 is shorter than a predetermined time, it is presumed that the worker is proficient in a specific task OP100, and "Level 1" is displayed. If the task interval time T5 is longer than the predetermined time, it is presumed that the worker is not proficient in the specific task OP100, and "Level 2" or the like is displayed. In other words, it can be said that the attribute information of the worker is a display method that does not include a time notation. The attribute information may be a work evaluation other than the proficiency. In this embodiment, as an example, of the task interval time T5 and the attribute information, only the task interval time T5 is displayed as shown in FIG. 5.

[0021] The information management device 2 is a portable device including a display unit 23. The portable device is, for example, a smartphone 4 or a tablet computer. In this embodiment, the information management device 2 is described as being a smartphone 4. In the following, the information management device 2 is described on the assumption that it is carried by a worker who works using the tool device 1. However, the information management device 2 may also be carried by, for example, a manager who manages the work tasks of the worker.

[0022] (2) Composition 1, the tool device 1 includes a control unit 11, an operation unit 12, a tool unit 13, a measurement unit 14, a transmission unit 15, a storage unit 16, and a power supply unit 17. Furthermore, the tool device 1 includes a body 100 as shown in FIG.

[0023] The body 100 accommodates or holds therein the tool unit 13, the control unit 11, the operation unit 12, the tool unit 13, the measurement unit 14, the transmission unit 15, the storage unit 16, and the power supply unit 17. The body 100 includes a cylindrical body portion 101 and a grip portion 102 that protrudes radially from the circumferential surface of the body portion 101 (see FIG. 3). An output shaft 133 of the tool unit 13 protrudes from one end side in the axial direction of the body portion 101. A battery pack 103 that houses the power supply unit 17 in a resin case is detachably attached to the grip portion 102 (the lower end in FIG. 2).

[0024] The control unit 11 can be realized by, for example, a computer system including one or more processors (microprocessors) and one or more memories. That is, the one or more processors execute one or more programs (applications) stored in one or more memories to function as the control unit 11. Here, the programs are pre-recorded in the memory of the control unit 11, but they may be provided via a telecommunication line such as the Internet, or recorded in a non-transitory recording medium such as a memory card. The control unit 11 has an acquisition unit 19 as shown in FIG. 1. That is, the control unit 11 has a function as the acquisition unit 19.

[0025] The operation unit 12 includes a trigger switch 121 provided on the grip portion 102. When the trigger switch 121 is operated, an operation signal having a magnitude proportional to the pull amount (operation amount) of the trigger switch 121 is input to the control unit 11.

[0026] The tool unit 13 includes a motor 131, an impact mechanism 132, an output shaft 133, and a drive circuit that controls the rotation of the motor 131 in response to a control signal input from the control unit 11. The output shaft 133 is provided with a socket 134 to which a bit (e.g., a driver bit) suited to a member to be worked on is detachably attached. The rotation of the rotating shaft of the motor 131 is transmitted to the output shaft 133 via the impact mechanism 132. If the output torque is equal to or lower than a predetermined level, the impact mechanism 132 is configured to reduce the rotation of the rotating shaft of the motor 131 and transmit it to the output shaft 133. If the output torque exceeds the predetermined level, the impact mechanism 132 is configured to apply an impact force to the output shaft 133 to screw in a screw or bolt of a fastening member. The motor 131 and the impact mechanism 132 are housed in the body unit 101.

[0027] The measurement unit 14 measures the tightening force applied by the tool unit 13. The measurement unit 14 measures the torque applied to the output shaft 133 with a magnetostrictive torque sensor 135 attached to the output shaft 133, and obtains the tightening force from the measurement value of the torque sensor 135. Note that the measurement unit 14 may measure the number of strikes applied to the output shaft 133 by the impact mechanism 132 with a vibration sensor, and obtain the tightening force from the number of strikes.

[0028] The transmitter 15 is a communication interface for communicating with the information management device 2 by wireless communication. The wireless communication is assumed to be wireless communication conforming to standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power wireless (specified low-power wireless) that does not require a license. The transmitter 15 may communicate with the information management device 2 via a public line network 6 such as the Internet.

[0029] The storage unit 16 is composed of a ROM (Read Only Memory), a RAM (Random Access Memory), etc. In the storage unit 16, individual identification information assigned to the tool device 1 used by the worker carrying the information management device 2 may be registered.

[0030] Power supply unit 17 is housed in battery pack 103. Power supply unit 17 includes a rechargeable battery, and is configured so that the rechargeable battery in power supply unit 17 is charged by connecting battery pack 103 removed from grip 102 to a charger. Power supply unit 17 supplies the electric circuit including control unit 11 and motor 131 with the power required for operation using the power stored in the rechargeable battery.

[0031] As shown in FIG. 6, the acquisition unit 19 acquires (generates) work information D1 including information for identifying a work interval time T5 between a first work OP1 included in a specific work OP100 and a second work OP2 subsequent to the first work OP1 and included in the specific work OP100. The acquisition unit 19 measures time using a timer. Here, the information included in the work information D1 includes the time when the first work OP1 was started. Furthermore, the information included in the work information D1 includes the fastening torque value measured by the measurement unit 14. As shown in FIG. 6, the work of the worker may continue from the first work OP1 to a second work OP2 subsequent to the first work OP1, a third work OP3 subsequent to the second work OP2, and so on. In this case, for example, as shown in FIG. 6, when a predetermined time (e.g., 30 minutes) has elapsed between the third work OP3 and the fourth work OP4, the acquisition unit 19 stops acquiring information related to the work information D1. That is, when a predetermined time T3 has elapsed since the last measurement and output of the fastening torque value, a timeout occurs, and the acquisition unit 19 stops acquiring the work information D1 including information for identifying the work interval time T5. For example, if a pass / fail judgment is not made on the fastening work in the next work (e.g., the fourth work OP4) included in the specific work OP100 until the predetermined time T3 has elapsed since a pass / fail judgment was made on the fastening work in one work (e.g., the third work OP3) included in the specific work OP100, the acquisition unit 19 stops acquiring the work information D1. As shown in Fig. 6, when there is no work OP0 before the first work OP1 and when the predetermined time T3 has elapsed and a timeout occurs, the work interval time T5 is displayed as 0 seconds on the display unit 23.

[0032] Next, the information management device 2 will be described.

[0033] The information management device 2 is a mobile terminal (e.g., a tablet computer or a smartphone) carried by a worker who uses the tool device 1. In this embodiment, the information management device 2 is described as a smartphone 4 (see FIG. 5). The information management device 2 is carried by the worker while the worker is performing work using the tool device 1, and is configured to manage the content of the work performed by the worker using the tool device 1. In this embodiment, the content of the work includes a work interval time T5 and a work operation time T4.

[0034] As shown in FIG. 1, the information management device 2 includes a signal processing unit 21, a receiving unit 22, a display unit 23, an operation unit 24, a sound output unit 25, and a storage unit 26.

[0035] The receiving unit 22 is a communication module that performs wireless communication in the same communication method as the transmitting unit 15 of the tool device 1. In this embodiment, the transmitting unit 15 of the tool device 1 is registered as a slave in the receiving unit 22 that serves as the master, and wireless communication is performed between the transmitting unit 15 and the receiving unit 22. Therefore, as an example, the tool device 1 and the information management device 2 used by the same worker are configured not to communicate with the tool device 1 and the information management device 2 of other workers within the communication range. In the tool system 3 of this embodiment, wireless communication is performed between the tool device 1 and the information management device 2, but the communication between the tool device 1 and the information management device 2 is not limited to wireless communication and may be wired communication. In this embodiment, the receiving unit 22 receives the work information D1 from the tool device 1, but the information management device 2 may be provided with a communication unit that can communicate with each other.

[0036] The display unit 23 is composed of a thin display such as a liquid crystal display or an organic EL (Electro Luminescence) display, and the display contents are controlled by the signal processing unit 21. The display unit 23 displays the operation interval time T5 based on the operation information D1. In this embodiment, the operation interval time T5 corresponds to the interval from when a pass / fail judgment result of the fastening torque based on the fastening torque value is output each time one operation (e.g., the first operation OP1) included in the specific operation OP100 is completed until when a pass / fail judgment result of the next operation (e.g., the second operation OP2) is output, and is displayed as time.

[0037] An example of a screen displayed by the display unit 23 is shown in FIG. 5. As shown in FIG. 5, instruction information is displayed in the display area A1 of the display unit 23 of the information management device 2. Specifically, as shown in the display area A1 of FIG. 5, a tool ID (column A10), a work location (column A11), materials used (column A12), a work name (column A13), torque setting (column A14), speed control (column A15), work date and time (column A16), and the like are displayed. The tool ID in the column A10 corresponds to the ID of a mutually authenticated tool. The work location in the column A11 corresponds to the place where the worker performs the work using the tool device 1. The materials used in the column A12 corresponds to the type of screws or bolts used by the worker in the work. In FIG. 5, "mtgold01" is displayed. The work name in the column A13 is the name of the work performed by the worker. For example, screw tightening work, and is displayed as "wnstart02" in FIG. 5. The torque setting in column A14 corresponds to the torque setting value of the tool device 1. The speed control in column A15 indicates whether or not speed control is enabled. The work date and time in column A16 indicates the work date and time of the worker. The display unit 23 displays columns A10 to A16 as an example, but is not limited to these displays, and there may be other displays as instruction information in addition to these displays, or there may be less displays than these displays.

[0038] As shown in FIG. 5, the display unit 23 displays the contents showing the work status in the display area A2 as an example. For example, in the case of screw tightening work, the total number of screws is displayed in the column A20, the number of OK screws is displayed in the column A21, the number of NG screws is displayed in the column A22, the work operation time T4 is displayed in the column A23, and the work interval time T5 is displayed in the column A24. The total number of screws in the column A20 corresponds to the total number of screws that the worker has tightened up to the present in a specific work OP100. For example, in FIG. 5, the total number is 1234 screws (pcs). The number of OK screws in the column A21 corresponds to the number of screws that have been judged as OK (judged as non-defective) out of the total number of screws that the worker has tightened up to the present. For example, in FIG. 5, the number of OK screws is 1000 screws (pcs). The number of NG screws in the column A22 corresponds to the number of screws that have been judged as NG (judged as defective) out of the total number of screws that the worker has tightened up to the present. For example, in FIG. 5, the number of NG screws is 234 screws (pcs). The operation operation time T4 in the column A23 corresponds to the time from the start of the operation to the output of the pass / fail judgment result when the worker tightens one screw. For example, in FIG. 5, the operation interval time is 58 seconds. In this embodiment, the operation interval time T5 in the column A24 corresponds to the time from the output of the pass / fail judgment result of the first operation OP1 to the output of the pass / fail judgment result of the second operation OP2 following the first operation OP1. For example, in FIG. 5, the operation interval time T5 is 798 seconds. As an example shown in FIG. 5, the display unit 23 displays columns A20 to A24, but the display is not limited to these displays, and there may be other displays as the operation status besides these displays, or there may be less displays than these displays.

[0039] 5, as an example, the display unit 23 displays a button A30 indicating the end of work in the display area A3. When the worker finishes the work for the day, this button A30 is pressed, and the work information D1 for the day stored in the memory unit 26 of the information management device 2 is acquired by the management device 7 via the public line network 6 and stored therein.

[0040] The operation unit 24 is, for example, a touch switch provided on a thin display constituting the display unit 23, and outputs a signal according to the operation to the signal processing unit 21.

[0041] The sound output unit 25 includes a speaker and a drive unit that drives the speaker. The sound output unit 25 outputs a notification sound such as a beep or a melody sound, or a voice message in response to a control signal input from the signal processing unit 21.

[0042] The storage unit 26 includes a ROM, a RAM, and an electrically rewritable non-volatile memory such as an EEPROM (Electrically Erasable and Programmable Read Only Memory).

[0043] The storage unit 26 may be a built-in memory, or may be a memory card removably connected to a card slot provided in the information management device 2. The storage unit 26 may also be stored in an external storage device (for example, a storage unit of the management device 7 connected to the information management device 2 via the public line network 6).

[0044] The signal processing unit 21 may be realized by, for example, a computer system including one or more processors (microprocessors) and one or more memories. In other words, the one or more processors execute one or more programs (applications) stored in one or more memories to function as the control unit 11. Here, the programs are pre-recorded in the memory of the control unit 11, but may be provided via a telecommunication line such as the Internet or recorded in a non-transitory recording medium such as a memory card. In this embodiment, the acquisition unit 212, the calculation unit 213, the determination unit 215, and the tool information acquisition unit 216 are realized by the arithmetic function of the processor.

[0045] The acquiring unit 212 acquires, from the tool device 1 via the receiving unit 22, work information D1 including information for identifying an operation interval time between a first operation included in a specific operation OP100 and a second operation subsequent to the first operation and included in the specific operation OP100. In this embodiment, the work information D1 is acquired by the acquiring unit 212 from the transmitting unit 15 of the tool device 1 via the receiving unit 22 of the information management device 2 every time a worker completes an operation such as a first operation and a second operation. In this embodiment, the work information D1 includes a start time of the worker's operation and a measured value of the fastening torque measured by the measuring unit 14.

[0046] The calculation unit 213 calculates the task interval time T5 and the task operation time T4 from the task information D1 acquired by the acquisition unit 212 (see FIG. 6). The task operation time T4 corresponds to the difference in time between the time T2 at which the judgment unit 215 outputs the pass / fail judgment result for one task (individual task) included in the specific task OP100 and the task start time T1 of that task, as shown in FIG. 6. The calculation unit 213 stores the calculation result in the storage unit 26. Here, the task information D1 includes the time at which the individual task started (i.e., the task start time T1 of the individual task) and the fastening torque value of the corresponding task. The time at which the individual task started (the task start time T1) is used to calculate the task operation time T4. That is, the task information D1 includes information for identifying the task operation time T4, which is the time required for an individual task included in the specific task OP100.

[0047] The judgment unit 215 judges whether the fastening is good or bad based on the fastening torque value. The judgment unit 215 receives the fastening torque value measured by the measuring unit 14 of the tool device 1 via the transmission unit 15 of the tool device 1 and the reception unit 22 of the information management device 2. The judgment unit 215 judges, for example, whether the fastening of the screw and the bolt is good or bad based on the received fastening torque value. For example, if the fastening torque value does not reach a predetermined value, the judgment unit 215 judges the fastening as "NG" as a faulty fastening. Also, if the fastening torque value reaches a predetermined value, the fastening is judged as "OK". The judgment result of the judgment unit 215 on the fastening is stored in the memory unit 26, and the display unit 23 displays the number of OK in the column A21, the number of NG in the column A22, and the total number in the column A20. These numerical values ​​are added up in real time and displayed each time a good or bad judgment result is obtained.

[0048] The tool information acquisition unit 216 acquires tool information regarding the specifications of the tool device 1 (such as the product number of the tool device 1 and information on the bit selected to match the screw to be tightened) from the tool device 1 associated with the information management device 2.

[0049] Furthermore, the information management device 2 has a function of communicating with a management device 7 via a public line network 6 such as the Internet. The management device 7 is configured with a server or the like. The server here is assumed to be one server device, but may be configured with multiple server devices, or such devices may form a cloud (cloud computing). Furthermore, at least a part of the functions of the information management device 2 (for example, the function of the determination unit 215) may be provided in the management device 7.

[0050] The specific operation OP100 corresponds to an operation performed in one day, for example. The specific operation OP100 may correspond to an operation performed over several hours, several days, one week, or one month. When the worker presses a button A30 labeled "End of Operation" in the display area A3 of the screen shown in FIG. 5 at the end of the day's work, the work information D1 for the day is stored in the management device 7 via the public line network 6. The management device 7 analyzes, for example, where the worker is spending time on the work based on the acquired data. Therefore, the management device 7 can analyze the work information D1 to improve the efficiency of the work and the process. For example, by looking at the analysis information, the manager who manages the work can determine that there is a problem with the settings of the tool device 1 when the work operation time T4 is longer than that of other workers. The manager can also determine that the worker's skill needs to be improved when the work interval time is long, even though there is no problem with the work operation time T4.

[0051] (3) Operation Next, the operation of the tool system 3 will be described with reference to Fig. 4 to Fig. 6. In the following, the operation of tightening a screw to fix a steel plate will be described as an example.

[0052] When the worker turns on the power of the smartphone 4, which is the information management device 2, and the tool device 1, the information management device 2 authenticates the tool device 1 and starts the management work related to the work (S1 in FIG. 4). In a state where the information management device 2 authenticates the tool device 1, the information management device 2 displays the instruction information displayed in the display area A1 in FIG. 5 (S2 in FIG. 4). Next, the information management device 2 transmits the setting value of the tool device 1 to the tool device 1 (S3 in FIG. 4). The tool device 1 stores the setting value in the storage unit 16 (S4 in FIG. 4). Next, the worker performs the screw tightening work using the tool device 1 (S5 in FIG. 4). At this time, the acquisition unit 19 acquires the start time at the time when the screw tightening work is started. Specifically, the acquisition unit 19 acquires the time when the worker pulls the trigger switch 121 (work start time T1) and registers it in the storage unit 16.

[0053] The measuring unit 14 of the tool device 1 measures the tightening torque value (measured value) and stores it in the memory unit 16. For example, when the measuring unit 14 records the highest tightening torque value and determines that the worker has completed the screw tightening work, the transmitting unit 15 transmits it to the information management device 2 as work information D1 including the work start time T1 and the tightening torque value (tightening force) (S7 in FIG. 4). When the receiving unit 22 of the information management device 2 receives the work information D1 including the work start time T1 and the tightening torque value, it registers it in the memory unit 26 (S8 in FIG. 4). The judging unit 215 judges the quality of the screw tightening work using the tightening torque value and registers the quality judgment result in the memory unit 26 (S9 in FIG. 4). In this case, if the tightening torque value is within a predetermined range of values, the judging unit 215 judges that the work is good, that is, OK, and if the tightening torque is not within the predetermined range of values, it judges that the work is bad, that is, NG. Moreover, the acquiring unit 212 acquires the time when the pass / fail judgment result is output (time T2 when the pass / fail judgment result is output) (S10 in FIG. 4), and registers it in the storage unit 26 (S11 in FIG. 4).

[0054] Next, the calculation unit 213 of the signal processing unit 21 calculates the operation operation time T4 by referring to the operation start time T1 acquired from the tool device 1 and the time T2 acquired in S10 of FIG. 4 (S12 of FIG. 4). Specifically, the operation operation time T4 is specified by calculating the difference between the time T2 at which the pass / fail judgment result in S10 of FIG. 4 is output and the operation start time T1 in S6 of FIG. 4. Also, as shown in FIG. 6, when the pass / fail judgment result for the first operation OP1 is output and the pass / fail judgment result for the second operation OP2 subsequent to the first operation OP1 is also output, it becomes possible to calculate the operation interval time T5. That is, the transmission unit 15 of the tool device 1 transmits the first information corresponding to the first operation OP1 and the second information corresponding to the second operation OP2 to the information management device 2 as the operation information D1. The first information is information including the operation start time T1 for the first operation OP1 and the measured value of the fastening torque. The second information includes the operation start time T1 for the second operation OP2 and the measured value of the fastening torque.

[0055] The calculation unit 213 specifies the operation interval time T5 by calculating the difference between the time T2 at which the pass / fail judgment result corresponding to the second operation OP2 stored in S10 of FIG. 4 was output and the time T2 at which the pass / fail judgment result corresponding to the first operation OP1 was output (S13 of FIG. 4). The worker repeats S5 to S13 of FIG. 4 to repeat the operation. When the work for one day is completed, the worker presses the button A30 indicating the completion of the work provided in the display area A3 of the screen of the display unit 23 of the information management device 2, and the information management device 2 ends the management work (S14 of FIG. 4). At this time, the information management device 2 transmits all the operation data stored in the storage unit 26 to the management device 7 via the public line network 6. The management device 7 saves all the operation data transmitted from the information management device 2 (S15 of FIG. 4).

[0056] (4) Advantages As described above, the tool system 3 includes the tool device 1 and the information management device 2. The tool device 1 includes the tool unit 13, the acquisition unit 19, and the transmission unit 15. The tool unit 13 is driven by a power source (power supply unit 17) and performs a specific operation OP100 on a work target. The acquisition unit 19 acquires work information D1 including information for identifying an operation interval from a first operation OP1 included in the specific operation OP100 to a second operation OP2 following the first operation and included in the specific operation OP100. The transmission unit 15 transmits the work information D1. The information management device 2 includes a reception unit 22 that receives the work information D1 from the tool device 1.

[0057] According to this configuration, the tool system 3 can specify the operation interval time T5, and can improve the work efficiency. For example, it is possible to grasp which of the multiple operations (first operation OP1, second operation OP2) included in a specific operation OP100 the worker is taking time to perform. In this case, by combining the operation interval time T5 with the pass / fail judgment result, it becomes possible to evaluate, for example, that a worker who has a short operation interval time T5 but many fail (fastening failure) judgment results lacks skills. This can lead to improvements in the process, and can improve the work efficiency.

[0058] (5) Variations The following are examples of modified examples. The modified examples described below can be applied in appropriate combination with the above-described embodiment.

[0059] The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. In addition, the same function as the tool system 3 according to the above embodiment may be embodied in a processing method, a computer program, or a non-transitory recording medium having a computer program recorded thereon.

[0060] Specifically, the processing method according to one embodiment includes an acquisition step and a transmission step. The acquisition step acquires work information D1 including information for identifying an operation interval time T5 between a first operation OP1 and a subsequent second operation OP2 included in a specific operation OP100 performed on a work target by a tool unit 13 driven by a power source. The transmission step transmits the work information D1 to the information management device 2.

[0061] The processing method according to the embodiment includes a receiving step in which the tool unit (13) driven by the power source receives, from the tool device 1, work information D1 including information for identifying an operation interval time T5 between a first operation OP1 and a subsequent second operation OP2 included in a specific operation OP100 to be performed on a work target.

[0062] Moreover, a program according to an embodiment is a program for causing one or more processors to execute any one of the above processing methods.

[0063] Modifications of the above embodiment are listed below. The modifications described below can be combined as appropriate and applied. Hereinafter, the above embodiment may be referred to as a "basic example."

[0064] The tool system 3 in the present disclosure includes a computer system. The computer system is mainly composed of a processor and a memory as hardware. The function of the tool system 3 in the present disclosure is realized by the processor executing a program recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, may be provided through an electric communication line, or may be provided by being recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as IC or LSI referred to here are called by different names depending on the degree of integration, and include integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Furthermore, a field-programmable gate array (FPGA) that is programmed after the manufacture of the LSI, or a logic device that can reconfigure the connection relationship inside the LSI or reconfigure the circuit partition inside the LSI, can also be adopted as a processor. The electronic circuits may be integrated in one chip or distributed across multiple chips. The multiple chips may be integrated into one device, or may be distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

[0065] (5-1) Variation 1 In the basic example, the information management device 2 is configured to display the task interval time T5 based on the task information D1, but is not limited to this configuration. The display unit 23 may display attribute information related to the worker. For example, the attribute information related to the worker is displayed based on the task interval time T5, with a worker with a short task interval time T5 being displayed as "Level 1" indicating a high level of proficiency, and a worker with a long task interval time T5 being displayed as "Level 2" indicating a low level of proficiency. In other words, the attribute related to the worker corresponds to displaying the content corresponding to the task interval time T5 in a display method different from the time display. In addition, both the task interval time T5 and the attribute information related to the worker may be displayed on the display unit 23.

[0066] (5-2) Variation 2 In the basic example, the information management device 2 is configured to have the determination unit 215, the acquisition unit 212, and the calculation unit 213, but is not limited to this configuration. The tool device 1A according to the modified example 2 may be configured to have the determination unit 5 and the acquisition unit 19 as shown in FIG. 7. In this case, the determination unit 5 starts the determination when a predetermined condition is satisfied. The acquisition unit 19 may measure the time from the output of the pass / fail determination result, which is the result of the pass / fail determination performed by the determination unit 5 for the first operation OP1, to the output of the pass / fail determination result for the next second operation OP2 as the operation interval time T5. In this case, the control unit 11 stores the operation interval time T5 in the storage unit 16 and transmits the operation information D1 including the operation interval time T5 to the information management device 2 via the transmission unit 15. The display unit 23 of the information management device 2 displays the operation interval time T5 included in the received operation information D1. Here, the predetermined condition for starting the determination is, for example, the measurement unit 14 measuring the maximum value of the tightening torque value.

[0067] (5-3) Variation 3 In the basic example, the operation interval time T5 is a time measured from the output of the pass / fail judgment result, which is a result of the pass / fail judgment performed by the judgment unit 215, until the output of the next pass / fail judgment result, but is not limited to this configuration. The operation interval time T5 may be a time from a first time point when the tool unit 13 starts an operation related to the first operation OP1 to a second time point when the tool unit 13 starts an operation related to the second operation OP2. Even in this case, the operation interval time T5 may be measured by the acquisition unit 19 of the tool device 1 or calculated by the calculation unit 213 of the information management device 2.

[0068] Here, when a predetermined time T3 has elapsed between acquiring information about the first operation OP1 and acquiring information about the second operation OP2, the acquisition unit 19 of the tool device 1 stops acquiring the work information D1 including information for identifying the operation interval time T5. For example, the information about the first operation OP1 is the time (first time point) when operation related to the first operation OP1 started, and the information about the second operation OP2 is the time (second time point) when operation related to the second operation OP2 started. Alternatively, the information about the first operation OP1 is the time when a pass / fail judgment result for the first operation OP1 was output, and the information about the second operation OP2 is the time when a pass / fail judgment result for the second operation OP2 was output.

[0069] (5-4) Variation 4 In the basic example, the operation operation time T4 is calculated by the calculation unit 213 of the information management device 2, but the present invention is not limited to this configuration. The acquisition unit 19 of the tool device 1 may acquire the operation information D1 including the operation operation time T4. In this case, the tool device 1 may have a determination unit, and the acquisition unit 19 may acquire information regarding the time from the time when the worker pulls the trigger switch 121 of the tool unit 13 to the time when the determination unit 5 outputs a pass / fail determination result based on the torque measurement value.

[0070] (5-5) Variation 5 In the basic example, the transmission unit 15 transmits the first information corresponding to the first task OP1 and the second information corresponding to the second task OP2 as task information D1 to the information management device 2 at different times. However, the transmission unit 15 may be configured to transmit the first information and the second information together as task information D1 to the information management device 2.

[0082] According to this embodiment, the time from a first point in time when the tool unit (13) starts operating for a first operation (OP1) to a second point in time when the tool unit (13) starts operating for a second operation (OP2) is defined as the operation interval time (T5), and information on the operation interval time (T5) can be acquired in the tool device (1), which is highly convenient.

[0083] In the tool system (3) according to the seventh aspect, in any of the first to sixth aspects, the acquisition unit (19) stops acquiring work information (D1) including information for identifying the work interval time (T5) when a predetermined time (T3) has elapsed between acquiring information about the first work (OP1) and acquiring information about the second work (OP2).

[0084] According to this embodiment, when the predetermined time (T3) has elapsed, the acquisition unit (19) stops acquiring the work information (D1), and thus it is possible to acquire the work information (D1) that reflects the actual work interval time (T5). This improves the accuracy of the work information (D1), and thus improves the work efficiency.

[0085] In the tool system (3) according to the eighth aspect, in any of the first to seventh aspects, the work information (D1) includes information for identifying the work operation time (T4), which is the time required by the worker to use the tool section (13) to perform individual tasks (first task OP1, second task OP2) included in a specific task (OP100).
