Definitions

  • the application relates to a device for driving a fastening element into a substrate.
  • Such devices usually have a piston for transmitting energy to the fastening element.
  • the energy required for this must be made available in a very short time, which is why, for example, with so-called spring nailers, a spring is initially tensioned, which suddenly transfers the tensioning energy to the piston during the driving process and accelerates it onto the fastening element.
  • the energy with which the fastening element is driven into the substrate is limited at the top in such devices, so that the devices cannot be used arbitrarily for all fastening elements and every substrate. It is therefore desirable to provide driving devices which can transfer sufficient energy to a fastener. Examples are from the WO03053638A1 , WO02051592A1 or US2009179062A1 known.

  • the motor should be accelerated quickly from standstill by reversing the direction of rotation with each cycle.
  • the energy source the battery
  • a lithium-ion battery Li-Ion battery
  • the electrical voltage of the battery drops when power is drawn from it. As the voltage drops, less voltage is available to the motor and therefore no arbitrarily high speeds can be achieved.

  • the device sequence looks as follows in one exemplary embodiment.
  • the user puts the device into operation by inserting the battery and operating the hand switch.
  • the control device checks whether all necessary signals (such as battery and electronics temperatures, voltages, battery type, etc.) are in a valid state and whether the device is ready for use. It is preferably in a relaxed position, the basic state. When starting, the control therefore assumes a relaxed state of the mechanical energy store.
  • the spindle nut is in the rear position. At this point, the nut sensor detects the position of the spindle nut, i.e. the information as to whether the spindle nut is in the rear position. If this is not the case, an attempt is made to move to this position.
  • the mechanical energy storage device is tensioned (motor rotated in tensioning direction).
  • the user triggers a settlement.
  • the device is immediately returned to its basic state. In order to achieve the fastest possible cycles, the device is immediately brought back into the tensioned state. A subsequent settlement is thus possible again. If the user does not want to carry out any further settlement, he releases the hand switch and the mechanical energy storage device is automatically relaxed. When relaxing, the stored energy is used to accelerate the tensioning mechanism back.
  • the control device must control the motor in such a way that it dissipates the unnecessary energy or feeds it back into the energy source.
  • the spindle nut When tensioning, the spindle nut is moved from the rear position to a front position. The state of the spindle nut signal changes. This information is saved as Reference value is taken and from this signal onwards a defined number of commutation steps (revolutions) is rotated and the position of the spindle nut on the spindle is continuously calculated based on these steps. While the motor is operated against the spring, the device status is monitored (such as main switch, current, voltage, temperatures, speed). Plausibility checks are preferably carried out during this. For example, it is checked whether the roll holder signal has changed as desired after a third of the clamping stroke or whether the latch is still closed as desired. If parameters or states are detected as incorrect, the device is released and an error message is displayed. Such errors are based, for example, on insufficient battery voltage or speed, excessively high temperature, immobile roll holder or the like.
  • the power to the motor is preferably regulated depending on the voltage applied to the battery contacts and / or the intermediate circuit.
  • the full power is given to the motor until the voltage has dropped to a defined value, for example 12 V. If this value is reached, the control reduces the power and regulates to this voltage value.
  • a current limiting control is also used, which ensures that a predetermined current strength is not exceeded.
  • the pressure signal is changed and the device control starts a time window of, for example, six seconds, in which a setting must take place or the device is lifted off again, otherwise the device is transferred to the relaxed state.
  • This function prevents a clamping point in the device, such as a jammed fastener guide, from causing the device to remain in a state that is ready to be triggered and thus enables it to settle without being pressed against the ground.
  • the latch is opened and the latch signal is changed.
  • the control device checks after changing the Latch signal whether the reel holder signal is also changed within a defined time, such as 100 ms. This sequence of signals provides information as to whether a settlement has been triggered (opening the pawl) and whether the piston and thus the reel seat have come to the relaxed position. If this sequence is not adhered to, for example because the fastening element is jammed and the mechanical energy storage device is not relaxed, the control device detects this, brings the device into the relaxed state and issues an error message.
  • the piston must be moved back into the coupling device as quickly as possible for an optimized process. This is done by driving the motor and thus the spindle in the return direction. For this, only a small amount of work is required by the motor in relation to tensioning. It is therefore possible to regulate the engine speed.
  • the control device continuously monitors the motor position signals or commutation steps and uses this to calculate the current position of the spindle nut on the spindle. This position is processed in order to allow the reset to take place as long as possible at high speed and to reduce it only shortly before reaching the pawl due to a short circuit in a generator mode.
  • the control device is provided to tension the mechanical energy store again as quickly as possible.
  • the control device does not start the renewed tensioning until it has been detected that the device has meanwhile been lifted from the ground and thus a fastening element has been able to move from the magazine into the fastener guide.
  • the mechanical energy storage is released and the control is deactivated.
  • Deactivating the controller reduces the power consumption of the control to a minimum ( ⁇ 1 mA) and thus does not drain the battery unnecessarily. Error states or service appointments are stored in the control device so they can be read out and the user is informed preferably via an optical and / or acoustic interface.
