In this embodiment, a motor 9 is driven by the power of a battery pack 5, a hydraulic pump 8 is driven by the driving force of the motor 9, and the hydraulic pressure of the hydraulic pump 8 causes a piston 7a in the cylinder section 7 to reciprocate and operate the tool head 3. This is a portable, cordless type power tool 1. Here, in order to make it easier to explain the positional relationship of each part of the power tool 1, the directions are indicated by X, Y, and Z arrows in the figure. The piston 7a reciprocates along the first axis P1. The power tool 1 operates normally in any direction, regardless of the direction in which it is used for work.

The tool head 3 is an example of a compression workpiece, and the power tool 1 is a multi-functional power tool in which the tool head 3 is replaceable.

[0022] Figure 2 is a schematic perspective view of the power tool 1 shown in Figure 1, viewed from the front, and Figure 3 is a schematic perspective view of the power tool 1, viewed from the rear. The main body 2 is housed inside a casing 2a and comprises a cylinder section 7 in which a piston 7a is arranged, an oil tank 6, a hydraulic pump 8 connected to the cylinder section 7 to supply hydraulic fluid from the oil tank 6 to the piston chamber of the cylinder section 7, a motor 9 connected to the hydraulic pump 8 to drive the hydraulic pump 8, and a first control unit 11 that drives and controls the motor 9. As an example, the hydraulic pump 8 is a swash plate type piston pump having a swash plate cam that rotates by the drive shaft of the motor 9. The battery pack 5, which supplies power to the motor 9 and the first control unit 11, is detachably connected to the control adapter 4. The battery pack 5 consists of a secondary battery such as a lithium-ion battery or a nickel-metal hydride battery. The control adapter 4 is detachably connected to the first connection section 2e in the main body 2. The first connection section 2e is connected to the handle 2d of the main body 2. The handle 2d is the grip portion held by the operator, and it is equipped with a start switch 2c. Pressing the start switch 2c makes the motor 9 operational. The first control unit 11 is, for example, a CPU consisting of a single-chip microcontroller.

[0023] The main unit 2 has a first connection part 2e, and the battery pack 5 has a fourth connection part 5b that can be engaged with and disengaged from the first connection part 2e. The control adapter 4 has a second connection part 4a that can be engaged with and disengaged from the first connection part 2e, and a third connection part 4b that can be engaged with and disengaged from the fourth connection part 5b, both provided on opposite sides. As shown in Figure 2, the control adapter 4 is connected to the first connection part 2e of the main unit 2, and the battery pack 5 is connected to the fourth connection part 5b of the control adapter 4.

[0024] The power tool 1 of this embodiment is used for compressing and crimping wires and crimp sleeves, and for compressing and crimping wires and crimp terminals, etc. Figure 8A shows an example of a crimp sleeve 51 among the wiring tools 50 applied to this embodiment, Figure 8B shows an example of a crimp terminal 52 among the wiring tools 50 applied to this embodiment, Figure 8C shows an example of a male die 71 among the processing tools 70 applied to this embodiment, and Figure 8D shows an example of a female die 72 among the processing tools 70 applied to this embodiment.

[0025] The wiring device 50 is equipped with a first identification unit 60 corresponding to first data representing the wiring device itself, and the processing tool 70 is equipped with a second identification unit 80 corresponding to second data representing the processing tool itself. For example, the first identification unit 60 is a first wireless tag, the second identification unit is a second wireless tag, and the recognition unit 20, described later, is an NFC reader.

Alternatively, for example, the first identification unit 60 is a first identification code, the second identification unit 80 is a second identification code, and the recognition unit 20, described later, is a code reader. The identification code is an adhesive sheet with a barcode or QR code (registered trademark) printed on it. This eliminates the need for large-scale equipment investment and enables rational construction management with reduced initial costs.

[0026] Figure 4A is a schematic plan view showing an example of the control adapter 4 according to this embodiment, Figure 4B is a side view of the control adapter 4, and Figure 4C is a bottom view of the control adapter 4. Furthermore, Figure 5A is a schematic perspective view of the control adapter 4 viewed from the front, Figure 5B is a schematic perspective view of the control adapter 4 viewed from the rear, and Figure 5C is a schematic perspective view of the control adapter 4 viewed from the bottom. The control adapter 4 includes a recognition unit 20, a communication unit 14, a second control unit 12, a display unit 13, a GPS circuit 15, and various other circuits. The recognition unit 20, communication unit 14, display unit 13, GPS circuit 15, detection circuit 16, power supply circuit 17, timer 18, and memory 19 are signal-connected to the second control unit 12.

[0027] The recognition unit 20 is configured to acquire first data from a first identification unit 60 located on the wiring device 50 and second data from a second identification unit 80 located on the processing tool 70, and is an NFC reader, for example. The recognition unit 20 is erected on the front side of the control adapter body, and the reader portion of the recognition unit 20 is angled upward, tilted at an angle that makes it easy to acquire the first and second data. An LED 25 for illumination is located above the recognition unit 20, and is positioned to illuminate the wiring device 50 and processing tool 70 as needed for easy visibility. A receptacle 24a for signal connection between an external memory or external signal line and an interface 24 inside the control adapter 4 is located above the recognition unit 20. The receptacle 24a can be made compliant with USB, RS-232C, or other known PC signal connection standards. A power switch 23 is located at the upper side of the control adapter 4. When the power switch 23 is turned ON, the control adapter 4 starts up.

[0028] The communication unit 14 is configured to be able to communicate wirelessly with external devices S. External devices S include mobile information terminals such as smartphones and tablet PCs, and data management servers connected to wireless communication devices. The wireless communication standards used by the communication unit 14 are compatible with external devices S and can be compliant with Bluetooth®, ZigBee®, SIGFOX®, LoRa®, NB-IoT, LPWA, NFC, Wi-Fi®, wireless LAN, and other known wireless communication standards.

[0029] The display unit 13 is configured to display images, and may utilize a liquid crystal display, organic EL display, or the like, and may include an external input function such as a touch panel as needed. A first switch 31 and a second switch 32 are located below the display unit 13. The first switch 31 and the second switch 32 are operated by the operator when changing the operating mode of the control adapter 4.

[0030] The GPS circuit 15 has a GPS receiving function and, as an example, acquires location data based on the location information of the place where the wiring device 50 is processed, and time data based on the time information when the wiring device 50 was processed.

[0031] The second control unit 12 controls the recognition unit 20, the communication unit 14, the display unit 13, the GPS circuit 15, and various other circuits. The second control unit 12 is configured to acquire tool data held by the first control unit 11, and the second control unit 12 and the first control unit 11 are signal-connected by connecting the control adapter 4 to the main unit 2. The second control unit 12 is, for example, a CPU consisting of a one-chip microcontroller.

[0032] Figure 6 is a schematic diagram showing an example of the circuit configuration of the power tool 1 according to this embodiment. The circuit configuration of the power tool 1 will be described below.

[0033] The power tool 1 is used for electrical work such as compressing and crimping electric wires 98 to crimp sleeves 51, compressing and crimping electric wires 98 to crimp terminals 52, and processing wiring devices 50, including other known electric wire terminals and crimping of electric wires together. A pressure sensor 7b that detects the pressure when the tool head 3 processes the wiring device 50 is located in the cylinder chamber of the cylinder section 7, and the output of the pressure sensor 7b is signal-connected to the first control unit 11. A temperature sensor 9a that detects the motor temperature is located in the housing of the motor 9, and the output of the temperature sensor 9a is signal-connected to the first control unit 11. The first connection section 2e of the main body section 2 is signal-connected to the second connection section 4a of the control adapter 4.

[0034] The control adapter 4 is used by being attached to the power tool 1. The recognition unit 20, communication unit 14, display unit 13, GPS circuit 15, detection circuit 16 for detecting the current flowing to the motor 9, power supply circuit 17 for supplying power to the motor 9, timer 18 for holding time data, memory 19 for storing data, interface 24, and LED 25 are signal-connected to the second control unit 12. The first switch 31 and the second switch 32 are used to change the operating mode of the control adapter 4 and are signal-connected to the second control unit 12. The third connection part 4b of the control adapter 4 is signal-connected to the fourth connection part 5b of the battery pack 5.

[0035] The battery pack 5 is used by being attached to the control adapter 4. For example, it is a high-capacity lithium-ion battery made up of many cells, and the DC power supply voltage it can supply is 80 to 240 [V]. The battery pack 5 detects the battery temperature by detecting the resistance value of the thermistor 5a. The thermistor 5a is signal-connected to the second control unit 12.

[0036] The communication unit 14 is configured to be able to wirelessly communicate with an external device S by pairing with it via Bluetooth®. The external device S is, for example, a smartphone, and for example, is configured to have an application program 90 installed on the smartphone for wireless communication with the communication unit 14, which allows access to a data management center corresponding to the type of power tool 1. This makes it easy to perform construction management using the external device S by simply accessing the network as needed and downloading and installing the application program 90 on the communication device. Furthermore, it is easy to update the control data necessary for construction management to the latest version.

[0037] Figure 7 is a schematic flowchart illustrating an example of the operation procedure of the control adapter 4 according to this embodiment. The schematic operation procedure of the control adapter 4 will be described below.

[0038] In step S1, when the power switch 23 is turned ON, the power supply to the motor 9 is cut off. By pressing and holding the first switch 31 and the second switch 32 simultaneously, the second control unit 12 acquires the tool data held by the first control unit 11. If tool data has already been acquired through repetitive work, etc., step S1 is omitted.

[0039] Once tool data is acquired, in step S2A, the second control unit 12 acquires location data from the GPS circuit 15 based on the location information of the place where the wiring device 50 is processed. Once the location data is acquired, the second control unit 12 controls the communication unit 14 and transmits the acquired tool data and location data to the external device S. The transmitted data is stored in the cloud. Note that data transmission at this stage is optional.

[0040] When the worker brings the ID card close to the recognition unit 20, in step S2B, the second control unit 12 controls the recognition unit 20 to acquire worker data from the worker ID card. Once the worker data is acquired, the second control unit 12 controls the communication unit 14 to transmit the acquired worker data to the external device S. The transmitted data is stored in the cloud. Note that data transmission at this stage is optional.

[0041] Once operator data is acquired, the system transitions to tool inspection mode. Subsequently, in step S3, the second control unit 12 controls the first control unit 11 to perform a crimping operation. The pressure of the tool head 3 during crimping is detected by the pressure sensor 7b, and the detected pressure signal is acquired. The crimping operation is performed a specified number of times, for example, three times.

[0042] After the operator performs the crimping operation three times, in step S4, the second control unit 12 calculates an output value based on the pressure signal from the pressure sensor 7b and determines whether the calculated output value is within the appropriate range.

[0043] In step S4, if the second control unit 12 determines, for example, that the output value is within the appropriate range three times in a row, it proceeds to step S5A and sends a signal to the display unit 13, in which step S5A displays the string "IDLE" indicating that the pre-processing state is appropriate. When it is displayed that the pre-processing state is appropriate, the unit enters an operation input waiting state.

[0044] In step S4, if the second control unit 12 determines, for example, that the output value is outside the appropriate range, it transitions to step S5B and sends a signal to the display unit 13. In step S5B, it displays the string "ERROR" indicating an output abnormality before processing. In addition, it displays the following strings depending on the error item. For example, if the output value is NG three times in a row, it displays the string "OUTPUT", if the current value is abnormal, it displays the string "CURRENT", and if the bypass is abnormal, it displays the string "BYPASS". If the first switch 31 is pressed and held while the output is abnormal before processing, it transitions to step S5C, enters a short-range communication enabled state, sends the data log to the external device S, and stops.

[0045] In step S5A, if the first switch 31 is pressed and held while the string "IDLE" indicating that the output value before processing is normal is displayed, the recognition unit 20 enters a data acquisition standby state, the string "READ" is displayed, and the process transitions to step S6A. In step S6A, if, for example, a male die 71 or female die 72 is brought close to the recognition unit 20, the recognition unit 20 acquires the second data, which is the ID of the processing tool 70, and the corresponding size of the processing tool 70 is displayed as a string, and the process transitions to step S6B. In step S6B, if, for example, a crimping sleeve 51 is brought close to the recognition unit 20, the recognition unit 20 acquires the first data, which is the ID of the crimping sleeve 51, and if the crimping sleeve 51 fits the size of the processing tool 70, the string "OK" is displayed after the corresponding size of the processing tool 70, and the process transitions to step S7.

[0046] In step S7, the second control unit 12 compares the acquired first data and second data with the acquired tool data and determines whether the combination data is correct or incorrect based on the wiring device 50, the processing tool 70, and the tool data. If it determines that the combination data is correct, it proceeds to step S8A and sends a signal to the display unit 13. In step S8A, it displays the string "OPERATION" indicating that the pre-processing state as the first state is correct and that processing work is permitted. When permission for processing work is displayed, the system enters an operation input waiting state.

[0047] In step S7, when the second control unit 12 determines that the combination data is incorrect, it sends a first error signal to the display unit 13, and in step S8B, it displays the string "ERROR" indicating an abnormality in the combination before processing. If the first switch 31 is pressed and held while the combination before processing is in an abnormal state, the process transitions to step S8C, short-range communication becomes possible, the data log is sent to the external device S, and the process stops.

[0048] After the operator performs the crimping operation three times, in step S9, the second control unit 12 obtains the processing data from the first control unit 11 when the wiring device 50 has been processed in accordance with the combination data, and then proceeds to step S10.

[0049] In step S10, the second control unit 12 determines whether the acquired processing data is within the appropriate range. If it determines that the processing data is normal, it proceeds to step S11A and sends a signal to the display unit 13. In step S11A, it displays the string "OPERATION" indicating that the post-processing state as the second state is normal and that processing work is permitted to continue. When permission for processing work is displayed, the system enters an operation input waiting state. If the first switch 31 is pressed and held while the processing result is normal, the system proceeds to step S12, short-range communication becomes possible, the data log is sent to the external device S, and the system stops.

[0050] In step S10, when the second control unit 12 determines that the acquired processing data is outside the appropriate range, it sends a second error signal to the display unit 13, and in step S11B, the display unit 13 displays the string "ERROR" indicating an abnormality in the processing data. If the first switch 31 is pressed and held while the processing result is abnormal, the process transitions to step S12, short-range communication becomes possible, the data log is sent to the external device S, and the process stops.

[0051] As an example, Table 1 shows the relationship between the items and management data managed by the second control unit 12 and the display operation of the display unit 13.

[0052] [Table 1]

[0053] As an example, Table 2 shows the relationship between the control operation of the second control unit 12 and the operation mode indicated by the string displayed by the display unit 13.

[0054] [Table 2]

[0055] According to this embodiment, the control adapter 4 and power tool 1 have a configuration that prevents human error, reduces the management burden on workers, and achieves improved construction quality.
