  • the invention further relates to a method for operating such a tool device or implement.
  • the hand-held power tool is, for example, a hand-held tacker, as disclosed in German Offenlegungsschriften DE 10 2006 000 517 A1 and DE 10 2006 035 460 A1.
  • the hand tool or implement may also be a hand-held device, as disclosed in German Patent DE 33 10 371 C1.
  • German Offenlegungsschrift DE 101 56 218 A1 discloses a hand-held or semi-stationary power tool with a device for storing machine-related data and with a device for detecting load conditions during operation of the power tool device and for converting the specific load states into the memory device storable load data, wherein a internal or external processor-controlled means for processing the load data, obtaining a service prediction and predicting the remaining no-break operating time, or issuing a fault message.
  • the object of the invention is to further simplify the operation of hand-held or semi-stationary tool devices or implements and / or to extend their service intervals or service life.
  • the object is in a hand-held or semi-stationary tool or implement, with a housing in which at least one mechanical actuator is arranged, which emits noise during operation of the power tool or work device, for example in the form of structure-borne noise, achieved in that the tool device at least a device for detecting occurring during operation of the power tool or implement noise comprises.
  • acoustic monitoring of the hand-held or semi-stationary tool or implement is made possible by detecting noises, in particular sound signals, at at least one selected location. As a result, damage to device components starting independently of a user can be reliably detected.
  • a preferred embodiment of the hand-held or semi-stationary power tool or implement is characterized in that the means for detecting occurring during operation of the power tool or implement noise comprises at least one microphone.
  • the microphone is preferably a relatively small component that can be easily accommodated in an existing housing of the hand-held or semi-stationary power tool or implement.
  • a further preferred exemplary embodiment of the hand-held or semi-stationary tool device or working device is characterized in that the device for detecting noises occurring during operation of the tool device or working device comprises at least one force sensor and / or a vibration sensor and / or a strain sensor.
  • the force sensor and / or the vibration sensor and / or the strain sensor are / is advantageously arranged in or on the housing such that the noises, in particular sound signals, are detected directly or in the vicinity of their point of origin. As a result, even smaller changes, especially operating noise, can be detected quickly and safely.
  • Another preferred embodiment of the hand-held or semi-stationary tool or implement is characterized in that several Means are provided for detecting occurring during operation of the power tool or implement noise at different locations in or on the housing.
  • the different locations may be determined, for example, by relatively simple measurements in the operation of the hand-held or semi-stationary tool or implement.
  • a further preferred exemplary embodiment of the hand-held or semi-stationary tool device or implement is characterized in that a device for detecting noises occurring during operation of the tool device or implement is arranged in a front / rear end region of the tool device or implement.
  • the tool or implement for example, is a bolt gun.
  • a bolt gun for example, includes a mechanical ram that is jerked with a relatively large force in a rear end portion of the bolt gun. The plunger releases the force or acceleration in the front end region of the bolt setting device to a bolt or nail which emerges with the aid of the plunger against a bolt setting end of the bolt setting device and is driven into a base.
  • the hand-held or semi-stationary power tool or implement is characterized in that the tool or implement is designed as a nailer, hand-held tacker or bolt gun.
  • the bolt gun can be a combustion-powered, a pneumatic or an electrically driven bolt gun.
  • the above-mentioned object is alternatively or additionally achieved by evaluating and using the noises detected by the device during operation of the power tool or implement in order, for example, to damage device components detect. As a result, unwanted consequential damage can be prevented.
  • a preferred embodiment of the method is characterized in that several device components are monitored simultaneously. With a microphone advantageously several device components can be monitored, which generate different noises during operation of the tool device or implement.
  • a further preferred embodiment of the method is characterized in that a user in the operation of the power tool or implement information about a fault in the operation of the power tool or implement are displayed immediately. The corresponding information is advantageously visually displayed.
  • a corresponding display device is attached, for example, on the outside of the housing of the implement or tool device.
  • a further preferred exemplary embodiment of the method is characterized in that the tool device is deactivated if a significant disturbance is detected during operation of the tool device or working device. This easily prevents a tool or implement from being used after a fault has occurred.
  • an inventive implement or tool device 1 with a housing 5 and a handle 6 is shown simplified in longitudinal section.
  • the tool device or implement 1 is an electrically driven bolt gun 3.
  • the invention is also applicable to combustion-powered or pneumatic bolt guns.
  • the invention in other tools or implements, such as drills, can be used.
  • the bolt setting device 3 is used for driving fasteners into a (not shown) underground.
  • the fasteners are acted upon and accelerated in the housing 5 by means of a mechanical actuator 8 by a mechanical plunger with a relatively large force.
  • the thus acted upon with force and acceleration fasteners exit at a setting end 10 of the housing 5.
  • the fasteners used are provided via a device-internal magazine 14, which is mounted in the vicinity of the setting end 10 of the tool or implement 1. From the magazine 14, the fasteners, preferably individually, automatically removed and provided at the setting end 10.
  • the energy required to drive the fastening elements into the substrate is released via the mechanical actuating device 8 in a front region 11 of the housing 5 to the respective fastening element.
  • the energy required to drive the fastening elements into the substrate is provided electrically.
  • the energy needed to drive the fasteners into the ground may also be provided in the rear area 12 in a fuel tank.
  • the energy required to drive the fasteners into the ground can be provided pneumatically.
  • the tool device or implement 1 comprises a device 20 for detecting noises occurring during operation of the tool device or implement 1, for example in the form of structure-borne noise.
  • the sound detection device 20 comprises a microphone 21 and a microphone 22.
  • the microphone 21 is arranged in the front region 11 of the bolt setting device 3. In this case, the microphone 21 is arranged in the vicinity of a front end of a plunger of the mechanical actuator 8.
  • the microphone 22 is arranged in the rear region 12 of the bolt setting device 3. In this case, the microphone 22 is disposed in the vicinity of a rear end of the plunger of the mechanical actuator 8.
  • the microphone 21 is connected via a line 23 to an evaluation unit 25.
  • the microphone 22 is connected via a line 24 to the evaluation unit 25. With the microphones 21 and 22 3 sound signals are detected in the front area 11 and in the rear portion 12 of the bolt setting device. The evaluation of these sound signals takes place in the central evaluation unit 25.
  • the central evaluation unit 25 is housed together with a controller 30 in a lower end of the handle 6 of the bolt setting device 3.
  • the evaluation unit 25 is operated with a software that is fixed depending on the device.
  • the software determines the parameters required for the function for a specific device type. This provides the advantage that an individual training phase for the respective device type can be omitted.
  • a disturbance in the operation of the bolt setting device 3 can be detected with the aid of the sound signals provided by the microphones 21 and 22.
  • the detected fault is visually displayed to a user of the bolt setting device 3 directly via a display device 26.
  • the information that there is a fault can alternatively or additionally be transmitted acoustically to the user, for example via suitable warning tones.
  • the display device 26 is connected via a line to the central evaluation unit 25.
  • the controller 30 is also connected to the evaluation unit 25. Via the signal line 32 and the controller 30, the bolt setting device 3 can also be deactivated automatically in the event of a significant failure. This prevents in a simple manner that the bolt-driver 3 is used further if there is a significant disturbance.
  • the invention provides, inter alia, the advantage that the required circuit complexity is relatively low.
  • the central evaluation unit 25 can be made very small.
  • the small dimensions of the evaluation unit 25 allow a simple way of integration into the housing 5. It can be advantageously dispensed with additional external modules or connection cable.
  • a corresponding evaluation program enables a reliable differentiation of differences in the handling and real or significant disturbances in the operation of the billet setting device 3.
