Description

  The present invention relates to a tool, and more specifically, detects the tool energization time and the actual number of hits to determine the maintenance time of the tool, and notifies the user when it is determined that maintenance is necessary.

  In the construction of housings, exteriors, and interiors of residential buildings, pneumatic tools and electric tools that continuously supply fasteners such as screws and nails are widely used. The parts that make up these tools have a predetermined durability, but as the number of hits on the fastener increases and the energization time of the motor elapses, the tip of the driver wears or the driver piston The impact absorbing effect of the bumper that absorbs the impact may be reduced. Therefore, for example, when the actual number of tool hits reaches several hundred thousand times, maintenance work such as overhaul is performed to replace the failed part. Furthermore, seizure of the air motor is prevented by periodically lubricating.

  In order to know the maintenance time, it is necessary to know the actual number of times the tool is hit and the energization time of the motor. As a tool for grasping the actual number of times the tool is hit, a tool including a proximity sensor that detects the reciprocating motion of the driver, and a counting circuit that counts the number of times the tool is hit based on a detection signal detected by the proximity sensor. Proposed. The actual number of hits of the tool counted by the counting circuit is displayed on the liquid crystal display device (see Patent Document 1). Thereby, the user can determine whether it is a maintenance time by reading the actual number of hits displayed on the liquid crystal display device.

JP 09-174460 A

  However, the tool disclosed in Patent Document 1 has the following problems. That is, since the actual number of times the tool is hit is only displayed on the liquid crystal display device, it is necessary for the user to determine whether or not it is a maintenance time. For this reason, the user himself / herself must grasp the actual number of hits that require maintenance, and may erroneously determine the maintenance time or forget the maintenance time due to the user's forgetfulness. When the maintenance time of the tool has passed, there is a problem that other parts are affected and the number of failure points increases, resulting in an extra part replacement cost.

Accordingly, the present invention is to solve the above problems, its object is to provide a Engineering tools for notifying accurately and reliably user maintenance timing.

In order to solve the above-described problem, the tool according to the present invention is a tool that strikes a stop by a striking mechanism driven by compressed air, and stops the striking motion by detecting an impact generated in the moving direction of the striking mechanism. The actual hit detection means by an acceleration sensor attached to the tool body so as to be perpendicular to the tool driving direction, and the number of actual hits of the tool obtained from the actual hit detection means, and a preset tool Storage means for storing the reference maintenance information, control means for determining whether or not the tool body is in a maintenance period based on a comparison result between the actual number of hits and the reference maintenance information, and the tool body is in a maintenance period If it is determined, with the tool body by a light emission signal corresponding to the content and notification means for notifying the user that a maintenance time, announcements Stage, the individual information of the tools stored in the storage means, characterized in that it is transmitted to the information processing apparatus by the light emitting signal.

  In the tool of the present invention, the maintenance information of the tool body is detected by the detecting means. The maintenance information is, for example, the actual number of times of hitting when the tool body is a pneumatic tool, and the number of times of actual hitting, the energization time of the motor, the number of battery replacements, etc. when the tool body is an electric power tool. The detected maintenance information is supplied to the control means.

  The control unit compares the maintenance information with reference maintenance information (threshold value) stored in advance in the storage unit. The reference maintenance information includes, for example, the actual number of times of hitting that serves as a reference when warning the part replacement time due to the durability of the tool, the number of times of oiling that requires oiling, and the like. The control means determines whether or not the tool body is in a maintenance period based on the comparison result. For example, when the maintenance information exceeds or exceeds the standard maintenance, it is determined that maintenance is necessary. Information based on the determination result is supplied to the notification means.

  The notifying means notifies the user that the tool body is in a maintenance period based on the determination result of the control means. For example, when the notification means is constituted by a light emitting unit, this light emitting unit is caused to flash and emit light to notify the user to that effect. If the notification means is constituted by a speaker, the fact is notified to the user by voice or buzzer sound. Thereby, the user can grasp | ascertain the components replacement | exchange time and lubrication time of a tool, before each component of a tool reaches | attains durability time by notification of a notification means.

  Here, the maintenance in the present invention refers to general maintenance, inspection, management, repair, etc. of tools such as hover hole and air motor lubrication performed when the tool reaches the specified actual number of times of hitting and the specified energization time. It includes the work of.

  According to the present invention, the control means determines the maintenance time of the tool based on the maintenance information, and the notification means notifies the maintenance time based on the determination result, so that the user can grasp the maintenance time of the tool reliably and accurately. can do. As a result, it is possible to prevent overload of the maintenance time, and it is possible to prevent the expansion of the part failure part by performing the part maintenance in advance.

[First Embodiment]
Embodiments of the present invention will be described below with reference to the drawings.
<Configuration of pneumatic tool>
FIG. 1 is a diagram illustrating a configuration example of a pneumatic tool 10A according to an embodiment of the present invention.
The pneumatic tool 10A includes a tool body 12 and a control board 50A. The tool body 12 includes a striking mechanism (not shown), a nose part 24, a contact part 26, and a screw tightening mechanism (not shown). The striking mechanism includes a striking cylinder, a striking piston slidably provided in the striking cylinder, and a driver bit integrally coupled to the striking piston. As shown in FIG. 1, when the trigger 16 is operated, compressed air is supplied from the air chamber 20 storing the compressed air into the striking cylinder, and the driver bit is driven. The air chamber 20 is formed inside the grip portion 18.

  The nose part 24 has an injection port for injecting a screw (stopper) onto the member to be tightened. The contact portion 26 as a safety device is slidably disposed on the nose portion 24 and urged so as to protrude toward the screw driving side, and the configuration of the trigger 16 is effective only when the contact portion 26 is pressed. It is comprised so that it may become.

  The screw tightening mechanism tightens and operates the driver bit by the power of the air motor. That is, almost simultaneously with the start of the operation of the striking mechanism, a part of the compressed air flowing from the air chamber 20 shown in FIG. 1 is supplied to the air motor 22 to rotate the driver bit around its axis. Then, the screw located at the injection port is fastened to a tightening member (not shown) such as a gypsum board by the rotating driver bit.

  The tool body 12 has a storage box 32 for storing a control board 50A that controls the maintenance time (part replacement time) of the tool body 12. The storage box 32 is provided in a space between the upper front portion of the magazine 30 and the lower front portion of the air motor 22.

  FIG. 2 is a diagram illustrating a configuration example of the control board 50A. As shown in FIG. 2, the control board 50A includes a board body 52, a memory unit 48, a control unit (tool control means) 54, a plurality of interfaces (insertion ports, hereinafter referred to as I / F) 68, a battery 66, a sensor unit 64, and a light emitting unit 62. The information processing apparatus 100 connected to the I / F 68 of the control board 50A will be described later.

  The substrate body 52 is a base body made of a material such as polyimide on which a wiring pattern (not shown) is formed, and is disposed inside the housing box 32 (see FIG. 1) of the tool body 12. The I / F 68 is provided at each corner of the main surface 52 a of the substrate body 52. The control unit 54 is composed of a microcomputer, and counts the actual number of hits of the tool body 12 and determines the maintenance time of the tool body 12.

  The memory unit 48 is an example of a storage unit, and includes a nonvolatile semiconductor memory (for example, a flash memory). The memory unit 48 stores maintenance information of the tool body 12. The maintenance information includes, for example, the cumulative actual hit count of the pneumatic tool 10A, the reference actual hit count as a reference when warning the maintenance timing, the reference lubrication count as a reference when warning the lubrication timing, and the pneumatic tool. Data such as a manufacturing number and manufacturing date / time of 10A are stored. The memory unit 48 may be integrated into the control unit 54.

  The battery 66 has a button shape and is disposed inside the tool body 12 (see FIG. 1). One end of a lead wire 66 a is connected to the battery 66, and the other end of the lead wire 66 a is connected to the substrate body 52 via the I / F 68. The battery 66 is configured to supply power to the control unit 54 and the like only when actual hitting of the tool body 12 is detected by the sensor unit 64. Thereby, the consumption of the battery 66 is reduced, and the number of replacements of the battery 66 can be reduced. Further, the use of the battery 66 can reduce the weight of the pneumatic tool 10A.

  The sensor unit 64 is an example of a detection unit, and includes, for example, an impact sensor or an acceleration sensor. One end of a lead wire 64 a is connected to the sensor unit 64, and the other end of the lead wire 64 a is connected to the substrate body 52 via the I / F 68. The sensor part 64 is accommodated in the accommodation box 32 such that the flat part 64b is perpendicular to the driving direction D (see FIG. 1) of the tool body 12. Thereby, the actual hit of the tool body 12 can be accurately detected. As a method for detecting the actual number of hits of the tool body 12, a sensor (switch) is attached to the trigger 16 and the contact portion 26 shown in FIG. Thus, the actual number of hits of the tool body 12 may be detected.

  The light emitting unit 62 is an example of a notification unit and a light emitting unit, and includes, for example, an LED or the like, and is attached to a position below the grip unit 18 of the tool body 12 (upper surface portion of the air motor 22) (see FIG. 1). One end of a lead wire 62 a is attached to the light emitting unit 62, and the other end of the lead wire 62 a is connected to the substrate body 52 via the I / F 68. Thereby, even when the pneumatic tool 10A is tilted and used in any direction such as a ceiling surface, a floor surface, or a wall surface, the user can easily visually recognize the light emission of the light emitting unit 62. The light emitting unit 62 can be attached to a position other than those described above as long as the user can visually recognize it.

  Next, a block configuration of the pneumatic tool 10A including the control board 50A will be described. FIG. 3 is a diagram showing a block configuration of the pneumatic tool 10A. As shown in FIG. 3, the sensor unit 64 of the pneumatic tool 10 </ b> A detects a shock or acceleration when the tool main body 12 is actually hit, generates a detection signal, and generates the detection signal as a control unit 54 and Supply to each of the batteries 66. The battery 66 generates electric power based on the supplied detection signal and supplies it to the control unit 54.

  The controller 54 includes a CPU (Central Processing Unit) 56, a ROM (Read Only Memory) 58, and a RAM (Random Access Memory) 60. The ROM 58 stores various programs for determining the maintenance time of the tool body 12, data necessary for processing, and the like. The RAM 60 is mainly used as a work area for various processes, such as temporarily storing and holding data obtained when the CPU 56 performs various processes. The CPU 56 executes a program stored in the ROM 58 to control maintenance warning and management of the tool body 12.

  After being activated by the power supplied from the battery 66, the control unit 54 determines whether the detection signal supplied from the sensor unit 64 is actual hit or non-actual hit. As a determination method, for example, a threshold value (voltage value) is stored in the ROM 58 in advance, and this threshold value is compared with the value of the detection signal (voltage value). . Further, the determination may be made based on the length of the duration of the detection signal. The control unit 54 counts the detection signal determined to be an actual hit, and generates a control signal for causing the light emitting unit 62 to emit light when the counted cumulative actual hit count exceeds a predetermined reference maintenance count. The light is supplied to the light emitting unit 62.

  The light emitting unit 62 emits light in a predetermined pattern based on the control signal supplied from the control unit 54, and warns the user that the tool body 12 is in a maintenance period. At this time, for example, when warning about the oiling time, the blinking pattern may be advanced, and when warning about the maintenance time such as overhaul, warning may be performed later than the flashing pattern of the oiling time. As a result, the user can easily identify what kind of warning is the content. The notification means may be a speaker that outputs a sound or a buzzer sound instead of the light emitting unit 62.

  When the maintenance information such as the actual number of hits stored in the memory unit 48 of the control board 50A is read by the information processing apparatus 100 described later, the control unit 54 reads the maintenance information stored in the memory unit 48 and reads the read maintenance information. A transmission signal based on the information is generated and supplied to the light emitting unit 62.

  The light emitting unit 62 converts the transmission signal supplied from the control unit 54 into a blinking signal (light emission signal) using infrared rays, and transmits (emits) the converted blinking signal. As the blinking signal, for example, a signal modulated by a carrier frequency is used.

<Operation of pneumatic tool>
Next, an example of the operation of the control unit 54 when warning the maintenance time of the pneumatic tool 10A will be described. FIG. 4 is a flowchart showing the operation of the control unit 54 when warning the maintenance time of the pneumatic tool 10A.

  In step S <b> 10, the control unit 54 detects the detection signal supplied from the sensor unit 64. In the control unit 54, it is determined from the waveform of the detection signal supplied from the sensor unit 64 whether actual hitting or non-actual hitting (blank hitting, etc.). In this example, it is assumed that the detection signal supplied from the sensor unit 64 is an actual hit. If a detection signal is detected, the process proceeds to step S20.

  In step S <b> 20, the control unit 54 updates the actual number of hits stored in advance in the memory unit 48. When the detection signal is supplied from the sensor unit 64, the control unit 54 reads the actual hit count from the memory unit 48, and adds +1 (increment) to the read actual hit count value to update the actual hit count. The updated actual hit count is stored again in the memory unit 48 as the cumulative actual hit count. After updating the actual number of hits, the control unit 54 proceeds to step S30.

  In step S30, the control unit 54 compares the cumulative actual number of times of hitting with a preset number of times of lubrication (reference maintenance information), and determines whether or not the actual number of times of hitting has exceeded the number of times of oiling. The control unit 54 reads the updated cumulative number of hits and the pre-stored number of lubrication times (threshold value) from the memory unit 48, and compares the cumulative number of actual shots and the number of times of lubrication. When the number of lubrication is set to 2000, for example, it is determined whether or not the updated cumulative actual number of hits exceeds 2000. The control unit 54 proceeds to step S32 shown in FIG. 5 when it is determined that the cumulative actual number of times exceeds the number of lubrication, and proceeds to step S40 when it is determined that the cumulative actual number of times is less than the number of lubrication.

  FIG. 5 is a flowchart showing the operation of the control unit 54 when the oiling timing is warned. In step S <b> 32, the control unit 54 performs a warning process to warn the user that the lubrication work is necessary when it is determined that the cumulative actual number of times of hammering has exceeded the number of lubrication. In the warning process, the control unit 54 supplies a control signal for causing the light emitting unit 62 to emit and blink, thereby causing the light emitting unit 62 to emit and blink in a predetermined pattern. The time for blinking the light emitting unit 62 can be arbitrarily set.

  In step S <b> 34, the control unit 54 compares the “cumulative actual driving number” with “the number of lubrication times + 10 times” and determines whether the “cumulative actual driving number” exceeds “the number of oiling times + 10 times”. As a result, the light emitting unit 62 blinks only during “+10 times” after the cumulative number of actual hits reaches the number of lubrication, so that the user can be surely noticed by the light emitting unit 62 during this time. For example, when the number of times of lubrication is set to 2000 times, the light emitting unit 62 blinks until the cumulative actual number of hits reaches 2010 times. The cumulative actual number of hits to be added is not limited to “+10”. For example, if the number of times greater than “+10 times” is added, the user can be warned that the lubrication work is necessary for a long actual number of times after the cumulative actual number of times of hitting reaches the specified number of times of oiling. If the control unit 54 determines that the “cumulative actual number of hits” exceeds “the number of lubrication times + 10”, the control unit 54 proceeds to step S36. On the other hand, if it is determined that the “cumulative actual number of hits” is less than “the number of times of lubrication + 10”, the process returns to step S10 and the detection signal is detected again.

  In step S36, the control unit 54 updates the numerical value of the number of times of lubrication. The control unit 54 reads out the number of times of lubrication from the memory unit 48. For example, when the number of times of lubrication is set to 2000 times, the number of times of lubrication is updated to 4000 times, and the updated number of times of lubrication is stored in the memory unit 48. To do. Thereby, when the cumulative number of actual hits reaches 4000 times, the light emitting unit 62 blinks again. Note that the newly set number of times of lubrication may be set so that the interval of the number of times of lubrication becomes shorter as the cumulative actual number of shots increases in consideration of aging deterioration. If the numerical value of the number of times of lubrication is updated, control part 54 will progress to Step S38.

  In step S38, the control unit 54 performs warning cancellation processing. In the warning canceling process, the control unit 54 causes the light emitting unit 62 to blink only for a predetermined time, and then stops the light emitting unit 62 from blinking. When the light emission stops, the process returns to step S10.

  Returning to FIG. 4, in step S <b> 40, the control unit 54 compares the cumulative actual hit count with a preset maintenance count (reference maintenance information) and determines whether the actual hit count exceeds the lubrication count. For example, if the maintenance count is set to 200,000 times, it is determined whether or not the updated actual hit count has exceeded 200,000 times. If the actual number of hits exceeds the number of maintenances, the process proceeds to step S42 shown in FIG. On the other hand, if the actual number of hits is less than the number of maintenances, the process returns to step S10 to detect the detection signal again.

  FIG. 6 is a flowchart showing the operation of the control unit 54 when a maintenance time is warned. Operations common to those in FIG. 5 will be described in a simplified manner. In step S42, the control unit 54 performs a warning process that warns the user that an overhaul operation is necessary. In the warning process, the control unit 54 supplies a control signal for causing the light emitting unit 62 to emit and blink, and causes the light emitting unit 62 to emit and blink in a predetermined pattern.

  In step S <b> 44, the control unit 54 compares “cumulative actual number of hits” with “maintenance number + 10 times” and determines whether “cumulative actual number of hits” exceeds “maintenance number + 10 times”. Thereby, since the light emitting unit 62 blinks only during “+10 times” after the cumulative number of actual hits reaches the number of maintenance times, the user can surely notice the warning by the light emitting unit 62 during this time. For example, when the number of maintenance times is set to 200,000 times, the light emitting unit 62 blinks until the cumulative actual hit number reaches 200,010 times. If the control unit 54 determines that the “cumulative actual number of hits” exceeds the “maintenance number + 10”, the process proceeds to step S46. On the other hand, if it is determined that the “cumulative actual hit count” is less than “maintenance count + 10”, the process returns to step S10 to detect the detection signal again.

  In step S46, the control unit 54 updates the numerical value of the maintenance frequency. The control unit 54 reads the maintenance frequency from the memory unit 48. If the maintenance frequency is set to 200,000 times, for example, the control unit 54 updates the maintenance frequency to double to 400,000 times, and updates the updated maintenance frequency to the memory unit 48. To remember. Thereby, when the cumulative number of actual hits reaches 400,000 times, the light emitting unit 62 blinks again. The control unit 54 proceeds to step S48 after updating the numerical value of the maintenance count.

  In step S48, the control unit 54 performs a warning cancellation process. In the warning cancellation process, the control unit 54 causes the light emitting unit 62 to blink only for a predetermined time, and then stops the light emitting unit 62 from blinking. When the warning cancellation process is completed, the process returns to step S10, and the detection signal is detected again. By such an operation of the control unit 54, when the actual number of hits reaches the prescribed number of times of lubrication or maintenance, the light emitting unit 62 blinks and warns, so that the user can accurately grasp the maintenance time.

  As described above, according to the present embodiment, when the cumulative actual number of hits of the pneumatic tool 10A reaches the preset maintenance count or lubrication count, the light emitting unit 62 flashes and emits light. Since the tool 10A warns that it is a maintenance time, the user can grasp the tool maintenance time reliably and accurately. As a result, it is possible to prevent overloading of the maintenance time, and it is possible to prevent the expansion of parts failure parts by repairing parts in advance. As a result, there is no need for extra costs such as repair.

The light receiving unit 124 receives the blinking signal (see FIG. 3) emitted from the light emitting unit 62 on the pneumatic tool 10A side, and converts the received blinking signal into an electrical signal. Then, the light receiving unit 124 performs processing such as amplification on the blinking signal converted into the electrical signal and supplies the signal to the control unit 1 30 .

  Here, the configuration of the blinking signal emitted from the light emitting unit 62 will be described.

For example, the end signal is set to be in an on state for a period of 1 ms, and then to be in an off state for a period of 16 ms or more. .

  Returning to FIG. 8, the control unit 130 includes a CPU 132, a ROM 134, and a RAM 136. The control unit 130 performs a decoding process by extracting the carrier frequency component of the blinking signal supplied from the light receiving unit 124 and generates an image signal based on the maintenance information.

<Usage example of information processing device>
Next, a usage example of the information processing apparatus 100 will be described. FIG. 10A is a diagram illustrating a usage example of the information processing apparatus 100, and FIG. 10B is an enlarged view of a main part S thereof.

  As shown in FIGS. 10A and 10B, when the cumulative actual number of hits is read from the pneumatic tool 10A, first, the power button 106 of the apparatus main body 102 is pressed to turn on the information processing apparatus 100 (see FIG. 10A). (See FIG. 8). Then, the cover member 122 of the receiving device 120 is pressed against (or brought close to) the tool body 12 so as to surround the light emitting portion 62 of the tool body 12. When the cover member 122 is pressed against the tool main body 12, a switch (not shown) provided on the tool main body 12 side is pressed to cause the light emitting portion 62 of the tool main body 12 to flash. Or, by removing the fasteners such as screws and nails, the memory 48 or the ROM 58 recognizes the impact waveform of the blank shot, and when the blank shot is generated several times in succession, the light emission blinks. The flashing light is turned on by an operation that cannot occur. With such an operation, the actual number of times the pneumatic tool 10 </ b> A is hit is read from the tool body 12 and displayed on the display unit 104 of the information processing apparatus 100.

Conventionally, when reading such actual hit count from the pneumatic tool 10A, these information is stored in the storage device of the engineering tool body 12, check how information has been very difficult. Therefore, through the wire to the substrate of the engineering tool body 12 to connect the fixture, but also how to get information from the substrate has been proposed, the substrate is taken out in this case by decomposing Engineering instrument body 12, the substrate There was a problem in that work efficiency was poor because the wire of the jig had to be connected to the upper connector.

  On the other hand, according to the present embodiment, since the maintenance information such as the actual number of hits is emitted using the light emitting unit 62 for warning the maintenance time of the tool body 12, the tool body 12 is disassembled and controlled. There is no need to take out the substrate 50A, and the working efficiency can be greatly improved. Accordingly, for example, in sales activities for selling tools to customers, the information processing apparatus 100 is brought to the customer, and maintenance information such as the actual number of hits is read from the customer's tools, so that the parts replacement time of the tools, etc. Can be judged on the spot, and this can lead to sales promotion of tools.

[Third Embodiment]
Next, the case where the electric tool 10B is used instead of the pneumatic tool 10A described above will be described. In addition, the same code | symbol is attached | subjected to the component which is common in the pneumatic tool 10A demonstrated in 1st Embodiment mentioned above, control board 50A, etc., and detailed description is abbreviate | omitted.

<Configuration of power tool>
FIG. 11 is a diagram showing a block configuration of an electric tool 10B according to the third embodiment. The electric tool 10B includes a control board 50B, a battery 66, a light emitting unit 62, a sensor unit 64, a motor 70, and a battery 72. The control board 50B includes a control unit 54 including a CPU 56, a ROM 58, and a RAM 60, a memory unit 48, a timer unit 142, and a plurality of I / Fs 68.

  The memory unit 48 is composed of a non-volatile semiconductor memory, and the memory unit 48 includes a maintenance time, an actual number of times of hitting, and a number of lubrication times as a reference for warning the motor energizing time of the electric tool 10B and the maintenance time of the electric tool 10B. Etc. are stored.

  The motor 70 is connected to the control unit 54 via the I / F 68, and supplies a drive signal generated when the motor 70 is rotationally driven by a trigger operation to the control unit 54. Further, the motor 70 supplies a stop signal generated when the rotational driving of the motor 70 is stopped to the control unit 54. The control unit 54 supplies a control signal based on each of the drive signal and the stop signal supplied from the motor 70 to the timer unit 142.

  The timer unit 142 measures the motor energization time based on the control signal supplied from the control unit 54. The measured motor energization time is added to the motor energization time already stored in the memory unit 48 and stored in the memory unit 48 again. That is, the accumulated motor energization time is stored in the memory unit 48.

  The battery 72 is connected to the control unit 54 and the motor 70 via the I / F 68. The control unit 54 counts the number of replacements of the battery 72, triggered by the operation when the battery 72 is attached to or removed from the electric tool 10B.

  In the electric power tool 10B configured as described above, a motor 70 is built in a housing (not shown). When the trigger is pulled, the motor 70 is operated, and the driver bit is rotated by the motor 70 via the rotation drive transmission unit. Perform screwing work.

<Operation of the power tool>
Next, an example of the operation when warning the maintenance time of the electric tool 10B will be described. FIG. 12 is a flowchart showing the operation of the power tool 10B.

  In step S100, the control unit 54 detects an ON operation of the motor. The control unit 54 detects the ON state of the motor based on the drive signal supplied from the motor 70 and supplies the control signal based on the drive of the motor 70 to the timer unit 142. In step S110, the timer unit 142 starts measuring the motor energization time based on the control signal supplied from the control unit 54, and proceeds to step S120.

  In step S120, the control unit 54 detects a detection signal based on the actual hitting of the electric power tool 10B supplied from the sensor unit 64, and proceeds to step S130. In step S <b> 130, the control unit 54 updates the actual hit count stored in advance in the memory unit 48. When the update of the actual hit count is completed, the process proceeds to step S140. In step S140, the control unit 54 updates the energization time of the motor. The detailed operation of this process will be described later.

  In step S150, the control unit 54 compares the cumulative actual number of times of hitting with a preset number of times of lubrication, and determines whether or not the actual number of times of hit exceeds the number of times of lubrication. When it is determined that the cumulative actual number of hits has exceeded the number of times of lubrication, the control unit 54 performs steps S32 to S38 shown in FIG. On the other hand, if it is determined that the cumulative actual number of hits is less than the number of lubrications, the process proceeds to step S160.

  In step S160, the control unit 54 compares the cumulative actual number of hits with a preset maintenance number, and determines whether or not the cumulative actual number of hits exceeds the number of lubrication. If the actual number of hits exceeds the number of maintenances, steps S42 to S48 shown in FIG. 6 are performed. On the other hand, if the actual number of hits is less than the number of maintenances, the process proceeds to step S170.

  In step S170, the control unit 54 compares the motor energization time with a preset maintenance time to determine whether the motor energization time has exceeded the maintenance time. The control unit 54 reads the updated motor energization time from the memory unit 48 and the maintenance time (threshold value) stored in advance, and compares the motor energization time with the maintenance time. When it is determined that the motor energization time has exceeded the maintenance time, the control unit 54 proceeds to step S172 shown in FIG. 13, and when it is determined that the motor energization time is less than the maintenance time, the control unit 54 returns to step S100.

  FIG. 13 is a flowchart showing the operation of the electric power tool 10B when the maintenance time is warned. In step S172, when the controller 54 determines that the motor energization time has exceeded the maintenance time, it performs a warning process to warn the user that maintenance work is necessary. In the warning process, the control unit 54 supplies a control signal for causing the light emitting unit 62 to emit and blink, and causes the light emitting unit 62 to emit and blink in a predetermined pattern.

  In step S174, the control unit 54 compares “motor energization time” with “maintenance time + 10 times” and determines whether “motor energization time” exceeds “maintenance time + 10 times”. Thereby, since the light emitting unit 62 blinks only during “+10 times” after the motor energization time reaches the maintenance time, the user can surely notice the warning by the light emitting unit 62 during this time. If the control unit 54 determines that the “motor energization time” has exceeded “maintenance time + 10 times”, the control unit 54 proceeds to step S176. On the other hand, if it is determined that the “motor energization time” is less than “maintenance time + 10 times”, the process returns to step S100.

  In step S176, the control unit 54 updates the numerical value of the maintenance time. After updating the maintenance time value, the control unit 54 proceeds to step S178.

  In step S178, the control unit 54 performs warning cancellation processing. In the warning cancellation process, the control unit 54 causes the light emitting unit 62 to blink only for a predetermined time, and then stops the light emitting unit 62 from blinking. When the warning cancellation process is completed, the process returns to step S100. By such an operation of the control unit 54, when the motor energization time reaches the specified maintenance time, the light-emitting unit 62 is blinked to give a warning, so that the user can accurately grasp the maintenance time.

  FIG. 14 is a flowchart showing detailed operations of steps S110 and S140 described above. In step S200, when the timer unit 142 detects energization of the motor, the timer unit 142 adds the motor energization time M_time. In step S210, the control unit 54 determines whether or not the motor energization time M_time has passed a predetermined update time, in this example, 60 seconds.

In step S220, when the control unit 54 determines that the motor energization time M_time has passed a predetermined update time, the control unit 54 reads the motor total energization time Total_M_time from the memory unit 48.
In step S230, the control unit 54 adds the total motor energization time Total_M_time, and updates the total motor energization time Total_M_time stored in the memory unit 48 in step S240.

  As described above, according to the present embodiment, as in the first embodiment, when the cumulative actual number of hits of the electric tool 10B reaches a preset number of maintenance times or lubrication times, When the time reaches the maintenance time, the light emitting unit 62 flashes and flashes to warn that the power tool 10B is in the maintenance time, so that the user can grasp the tool maintenance time reliably and accurately. As a result, it is possible to prevent overloading of the maintenance time, and it is possible to prevent the expansion of parts failure parts by repairing parts in advance.
