Description

Tools and power tools

The present invention relates to a tool including a mechanism for informing a mechanical state and a power tool.

In the conventional electric power tool, the light is blinking, the LED is blinking, or the buzzer is sounded to inform the state of the machine (for example, the residual amount of the consumables or an error, etc.) (see, for example, Patent Document 1).

[Patent Document 1] Japanese Patent Laid-Open Publication No. 2009-184075

However, when using an LED or a buzzer as before, there is an operator who has not noticed the notification because of the work environment. For example, when it is an LED, it is difficult to understand the problem of the lighting state in a bright working environment such as an outdoor house. Moreover, when it is a buzzer, there is a problem that it is difficult to hear sound in an operating environment with a high noise level.

When the operator does not notice the continuous operation, the work efficiency is lowered, or the risk of mechanical failure is increased. For example, even if the residual amount of the consumables is told that the operator has not noticed the notification, there is a time when the consumables are exhausted and the operation is interrupted or must be remade. Moreover, when the operator does not notice the abnormality of the mechanical high temperature or the motor lock, the risk of mechanical failure increases. Further, when the operator does not notice that the battery residual amount is lowered, the battery pack is used in an overdischarged state, which may cause a decrease in battery life.

Here, the present invention will provide an operator who can easily notice the information notification tool and the power tool as a subject even in a work environment where the work environment or the noise level is high.

The present invention has been developed to solve the above problems, and is a portable tool or a power tool in which a grip is held for use, and includes a vibration generating device that generates vibration in order to notify the state of the machine.
[Effect of the invention]

As described above, the present invention includes a vibration generating device that generates vibration in order to inform the state of the machine. Therefore, even in a work environment with a bright working environment or a high noise level, the operator can take notice of the vibration of the vibration generating device and notice the information. Moreover, by using the vibration, the operator directly feels the sense of disobedience, so the notification can be noticed sensorily.

Embodiments of the present invention will be described with reference to the drawings. Further, in the following description, the electric power tool 10 will be described by taking an example of a driving tool for ejecting a fastener (in the present embodiment, a staple type in the present embodiment) from the ejection opening 20a. However, the driving tool is merely an example of the electric power tool 10. The power tool 10 of the present invention can be applied at least as long as the portable power tool 10 is held by the grip 21, and the type of the power tool 10 is not particularly limited.

The electric power tool 10 of the present embodiment is covered with a casing 11 as shown in Fig. 1 . The power tool 10 includes an output portion 20, a grip 21, a magazine 23, a motor housing portion 24, and a battery assembly portion 25.

The output unit 20 houses a portion of a driver (not shown) for driving a fastener. The actuator is slidable in the longitudinal direction of the output portion 20. At the tip end of the output portion 20, an injection port 20a is opened, and the fastener before being punched directly in front of the injection port 20a is in standby. When the trigger 22 described later is operated and the driver slides in the direction of the ejection opening 20a, the fastener that stands by directly in front of the ejection opening 20a is driven by the driver to be ejected from the ejection outlet 20a, and is driven into the driven material. .

The grip 21 is a rod-shaped portion that is held by the operator when the power tool 10 is used. This grip 21 is connected so as to be substantially orthogonal with respect to the output portion 20. In detail, the grip 21 is connected to the rear side of the output unit 20 when the output unit 20 is viewed in the direction in which the fastener is driven. Here, the grip 21 is provided with a trigger 22 for actuating the power tool 10. The trigger 22 is disposed at a position where the index finger can be hooked after the operator holds the grip 21. When the operator pulls the trigger 22 to operate, the micro switch 22a (refer to FIG. 2) built in the grip 21 is turned ON. When the micro switch 22a is turned ON, the electric signal is transmitted to the control board 27, and by the control board 27, the motor 24a is driven and controlled, and the electric power tool 10 is actuated, and the fastener is driven.

Further, inside the grip 21, a vibration generating device that generates vibration in order to notify the state of the machine is disposed. The vibration generating device of the present embodiment is configured by attaching a weight to a rotating shaft of the vibration motor 35. The configuration of the counterweight is installed with a center of gravity offset with respect to the rotating shaft of the vibration motor 35, and when the vibration motor 35 rotates, the vibration is applied by the counterweight to generate vibration.

As shown by the arrow in Fig. 3, the vibration motor 35 is configured to vibrate in a direction orthogonal to the direction of the axial direction of the grip 21. In other words, the rotation shaft of the vibration motor 35 is arranged substantially in parallel with respect to the axial direction of the grip 21. With this configuration, the vibration is easily transmitted to the hand holding the grip 21.

The magazine 23 is used to load the fastener. In the present embodiment, the fastening fastener that connects the fasteners into a rod shape can be loaded into the magazine 23. The magazines 23 are connected so as to be substantially orthogonal with respect to the output unit 20, and are arranged substantially in parallel with respect to the grip 21. In detail, the magazine 23 is connected to the front position of the output unit 20 when the output unit 20 is viewed in the direction in which the fastener is driven. The tip end of the magazine 23 is in the interior and communicates with the output portion 20 to supply a fastener to the tip end of the output portion 20 (near the ejection opening 20a).

The motor housing portion 24 is provided adjacent to the magazine 23, and as shown in Fig. 3, the motor 24a is housed. The motor 24a is used to activate the driving source of the electric power tool 10. The rotation of the motor 24a is controlled by a control board 27 which will be described later. In the present embodiment, the motor 24a is rotated, and the driver performs the driving operation while the actuator is returned to the standby position.

Further, on the inner side surface (the surface facing the grip 21) of the motor housing portion 24, a light guiding portion 30 for guiding the light of the light source 28 to be described later is provided. The light guiding portion 30 is formed of a transparent or translucent resin, and the light incident on the light source 28 causes the incident light to diffuse inside, and the light can be emitted from the surface. Thereby, the light of the light source 28 is easily visually recognized by the operator.

The battery assembly portion 25 is used for a portion where the battery pack 26 can be attached or detached. The battery assembly portion 25 is provided at a lower end of the grip 21 (an end portion on the opposite side of the output portion 20). In other words, the output portion 20 is connected to the end of one side of the grip 21, and the battery assembly portion 25 is connected to the other end.

Further, in the present embodiment, the battery pack 26 is slidably attached to the lower surface of the battery assembly portion 25. Although not specifically illustrated, a latch body is provided on the upper surface of the battery pack 26, and the latch system is engaged with the lower surface of the battery assembly portion 25, whereby the battery pack 26 is mounted to the power tool 10. on. When the battery pack 26 is mounted on the electric power tool 10, the battery pack 26 and the electric power tool 10 are electrically connected, and the electric power stored in the battery pack 26 can be used by the electric power tool 10.

In this battery assembly portion 25, a control board 27 for controlling the operation of the electric power tool 10 is built in. As shown in Fig. 3, the control substrate 27 has a surface facing the grip 21 side, and the inner surface faces the battery pack 26 side. On the surface facing the grip 21 side, various electronic components are assembled, for example, a light source 28 composed of an LED or a sound source composed of a buzzer is assembled. Further, a terminal for electrically connecting to the battery pack 26 is provided on the inner surface facing the battery pack 26 side.

Further, the light source 28 assembled on the control board 27 is illuminated by the controller in order to inform the state of the machine. Further, the sound source assembled to the control board 27 is output to the controller in order to inform the state of the machine. Further, as described above, the vibration motor 35 vibrates in order to inform the state of the machine. In this way, the electric power tool 10 of the present embodiment is a plurality of notification means including the vibration motor 35, the light source 28, and the sound source, and can notify the state of the machine.

The plurality of notification mechanisms informs, for example, the state of the residual amount of the fastener, the state of charge of the battery pack 26, the temperature state of the battery pack 26, or the abnormal state of the machine. Moreover, the notification of the residual amount state of the fastener is performed when the residual amount of the fastener in the magazine 23 is detected to be small. Further, the notification of the state of charge of the battery pack 26 is performed when the remaining amount of charge of the battery pack 26 is detected to be small. Further, the notification of the temperature state of the battery pack 26 is performed when the battery composition is detected to be high temperature. Further, the notification of the abnormal state of the machine is a notification that is executed after the mechanical abnormality of the machine is detected to be high temperature or the motor 24a is locked.

In this way, in the present embodiment, the plurality of notification mechanisms are included, and the plurality of notification contents (the residual amount state of the fastener, the state of charge of the battery pack 26, and the abnormal state of the machine) are included. In this aspect, it is also possible to automatically switch between the use of the plural notification mechanism in response to the notification content.

For example, as shown in FIG. 4(a), when the content is "A" (for example, the notification of the residual amount state of the fastener), the light or the flashing light source 28 can also be used for notification, and the sound source and the vibration motor 35 can be used. Not moving. Moreover, when the content is "B" (for example, the notification of the state of charge of the battery pack 26), the sound may be outputted from the sound source for notification in addition to the light or flashing light source 28, and the vibration motor 35 is not activated. . Further, when the content is "C" (for example, the notification of the abnormal state of the machine), the sound may be output from the sound source in addition to the light or the flashing light source 28, and the vibration vibration motor 35 may be used for notification.

In this way, if the notification mechanism corresponding to the notification content is different, which state is notified by the notification mechanism, the state of the machine can be grasped. Further, the aspect shown in the fourth diagram (a) is merely an example, and of course, the combination of the notification means or the setting of the notification content can be arbitrarily set.

Further, when the state of the machine is notified, it is also possible to manually switch which of the plurality of notification mechanisms is used by operating a switch or the like included on the body of the electric power tool 10.

For example, as shown in FIG. 4(b), the light source 28, the sound source, and the vibration motor 35 may be switched to or not used by the operator. At this time, it is also possible to provide a switch that can operate the switching light source 28, the sound source, and the ON/OFF of the vibration motor 35. For example, when the light source 28 is turned ON and the vibration motor 35 is turned off, when the power tool 10 informs the state of a certain machine, the light source 28 and the sound source are used for notification, and the vibration motor 35 is not activated.

In this way, if it is manually switched whether or not the plural notification mechanism is used, the notification mechanism can be selected according to the preference of the operator or the work environment. Further, in the example shown in FIG. 4(b), ON‧OFF may be selected for all the notification mechanisms. However, the present invention is not limited thereto, and only one of the notification mechanisms may be selected to be ON‧OFF. . For example, the light source 28 and the sound source may always be ON, and only the vibration motor 35 may be switched ON/OFF.

Further, in the above embodiment, the vibration motor 35 or the sound source is built in the electric power tool 10. However, the embodiment of the present invention is not limited thereto, and the vibration motor 35 or the sound source may be built in the external terminal 40 that is wirelessly connected to the electric power tool 10. That is, as shown in FIG. 4(c), the external terminal 40 such as a mobile phone having the vibration motor 35 or the sound source built therein and the electric power tool 10 are wirelessly connected using a Bluetooth (registered trademark) interface or the like. Further, when the state of the machine is notified, the power tool 10 wirelessly outputs a signal to the external terminal 40, and the external terminal 40 that receives the signal vibrates the vibration motor 35 of the external terminal 40. Further, the external terminal 40 that receives the signal can also output sound from the sound source of the external terminal 40 in conjunction with vibration or instead of vibration. According to this configuration, the state of the machine can be notified by shaking the external terminal 40 around the operator (or outputting sound from the sound source of the external terminal 40).

As described above, according to the present embodiment, it includes a vibration generating device (vibration motor 35) that vibrates in order to notify the mechanical state. According to this configuration, even in the environment where it is difficult to notice the notification by the light source 28 or the sound source, that is, even in a bright working environment or a work environment with a high noise level, the operator can borrow The vibration of the vibration generating device, notice the notification of the information. Moreover, by using the vibration, the operator has a sense of sense of violation, so that the sensation can be noticed.

Further, since the vibration generating device is disposed inside the grip 21, the vibration can be directly applied to the operator's hand, and the operator can easily notice the notification.

Further, the arrangement is such that the vibration generating means vibrates in the direction of the substantially orthogonal direction with respect to the axial direction of the grip 21, whereby the vibration is easily transmitted to the hand holding the grip 21, and the operator can easily notice .

Further, the vibration generating means is preferably disposed to contact the inside of the grip 21 of the operator's palm when the operator holds the grip 21. By arranging the inside of the position where the palm is in contact, the operator can easily notice the vibration of the vibration generating device in comparison with the inner side of the position where the fingertip is placed. For example, as shown in FIG. 2, when the axial direction of the grip 21 is approximately orthogonal to the output direction of the electric power tool 10 (the direction in which the fastener is driven), the vibration motor 35 is disposed when viewed in the output direction of the electric power tool 10 It is closer to the front side than the center of the grip 21, whereby the vibration generated by the vibration motor 35 can be easily transmitted to the operator.

Further, it includes a light source 28 that is illuminated to notify the mechanical state, and a plurality of notification mechanisms that are composed of at least two of the vibration motor 35, the light source 28, and the sound source, and the sound source that is output controlled for notifying the mechanical state. The status of the machine can be informed. When based on this configuration, the operator can easily notice the notice by using the plural notification mechanism.

Further, in the above embodiment, the notification mechanism includes the vibration motor 35, the light source 28, and the sound source. However, the present invention is not limited thereto, and may not include the light source 28 or one of the sound sources. Further, the notification means other than the above three may be included.
Further, in the above-described embodiment, the vibration generating device (vibrating motor 35) is provided on the electric power tool 10 that uses the motor 24a as the driving source. However, the present invention is not limited thereto, and may be driven by different driving. A vibration generating device is provided on the tool of the source.
For example, Fig. 5 shows a pneumatic tool 45 of Modification 1. The pneumatic tool 45 shown in this modification 1 is a nailing machine that uses compressed air to drive the driving mechanism. When the vibration generating device is provided on the pneumatic tool 45, for example, the vibration generating device can be used to notify the remaining amount of consumables such as fasteners, or the notification of the abnormality of the tool, the notification when the safety device is activated, and the like. .
Moreover, in the pneumatic tool 45, the grip 21 is used as a pressure vessel, and therefore, the vibration motor 35 is preferably disposed near the grip 21 (e.g., across the boundary between the grip 21 and the output portion 20).
Also, the pneumatic tool 45 generally does not use electrical power. Therefore, although a battery for driving the vibration motor 35 is necessary, the vibration motor 35 for transmitting information is small and sufficient, so that a small battery is sufficient, and a vibration including the vibration motor 35 and the battery can be mounted. A device is produced. In this way, even if an electrical tool is not used, a vibration generating device can be mounted.
Further, Fig. 6 shows a gas burning type nailer 46 according to the second modification. The tool shown in this modification 2 drives the nailing machine of the driving mechanism by the combustion pressure of the gas. When the vibration generating device is provided in the gas burning type nailing machine 46, for example, the vibration generating device can be used to notify the remaining amount of consumables such as fasteners, or the notification that the residual amount of the battery is small, and the tool abnormality. The notification, the notification that the safety device has been activated, etc.
Further, in the gas burning type nailer 46, a battery for driving a fan for fuel agitation or an ignition device is mounted, so that it is not necessary to add a battery for driving the vibration motor 35. Therefore, the vibration generating device can be mounted without increasing the size of the tool.
Further, in the above-described embodiment, an example in which a vibration generating device (vibration motor 35) is provided in a tool using a consumable such as a fastener is described. However, the present invention is not limited thereto and may not be used. A vibration generating device is provided on the tool of the consumable.
For example, Fig. 7 shows an impact driver 47 of Modification 3. In the impact driver 47 of the third modification, the rotational energy of the switching motor 24a is the striking force and the rotational force, and is transmitted to the driver head 48 attached to the tip end of the output portion 20, whereby the screw or the bolt is locked. As shown by the impact driver 47, even if a tool for consumables such as a fastener is not used, by providing a vibration generating device, for example, the vibration generating device can be used to notify the abnormality of the tool, the notification that the safety device has been actuated, and the like.
