Definitions

  • the invention relates to a tacker according to the preamble of claim 1.
  • a mechanical energy store means any component that can absorb and temporarily store mechanical energy.
  • it may be a gas spring or preferably an elastically deformable Act solid.
  • an elastically deformable solid are inter alia coil springs, coil springs, disc springs, torsion bars, elastic bands of an elastomer or the like to understand.
  • each retractable nail, bolt or screw understood.
  • the propellant gas in preferred embodiments is air, in particular ambient air. But it can also be gases such as air, nitrogen or carbon dioxide from a pressure reservoir or to reaction gases from a combustion.
  • the energy store comprises an elastically deformable solid.
  • Such energy storage generate little heat loss and can be well combined with respect to their spring constants for combination with the gas space.
  • the energy store comprises a rubber-elastic membrane, wherein the membrane forms the further wall portion.
  • the energy store comprises a piston as a further wall section and a spring, wherein the piston is supported against the spring.
  • the advantages of mechanical springs, in particular metal springs can be used with regard to their small installation space and the high possible spring constants.
  • the piston is movable in the same direction of movement as the piston of the energy transmission element. This allows a Particularly simple design of the remaining housing wall of the gas space, for example as a simple or stepped cylinder.
  • the drive gas is conveyed into the gas space by means of a compressor, which is preferably integrated in the housing.
  • a compressor which is preferably integrated in the housing.
  • the compressor preferably comprises an electric drive, wherein the electric drive is particularly preferably driven by an accumulator as an energy source. This allows a wireless device, while the high energy densities of modern batteries can be used at the same time.
  • the drive-in device according to the invention Fig. 1 comprises a hand-held housing 1, in which a power transmission element 2 is accommodated with a drive device 3.
  • the drive device comprises a gas space 7, which can be filled by means of a compressor 9 with a drive gas at a defined pressure.
  • the energy transmission element 2 comprises a drive element 2a in the form of a substantially cylindrical plunger. In a front region of the tacker, a damping stop 4 for the energy transmission element 2 is arranged.
  • Fasteners are received in a magazine 5.
  • a feed mechanism (not shown)
  • a fastener is in each case transported into a chamber, from where it is accelerated by the action of the drive member 2a and driven through a mouth part into a workpiece (not shown).
  • the driving member 2 a is connected to a piston 2 b of the power transmission element 2, wherein the piston 2 b is guided in a cylinder 6.
  • the gas space 7 can be filled with a drive gas, in the present case compressed air, under an overpressure relative to the external pressure.
  • the gas space 7 is enclosed by a rigid wall section which also comprises a pressure-side part of the cylinder 6, the movable piston 2b as the first variable wall section and a rubber-elastic membrane 8 as the second variable wall section.
  • the elastomeric membrane 8 expands depending on the pressure or degree of filling of the gas space 7 against an inherent material tension. As a result, it forms a mechanical energy storage in which energy is stored in addition to the energy in the pressurized gas. To avoid overstretching of the membrane, it is surrounded by a rigid housing wall 1a, against which it can rest at maximum expansion.
  • the compressor 9 is driven by an electric drive, for example a rotating electric motor in conjunction with an oscillating mechanism.
  • the power source of the electric drive is an accumulator 10 provided on the housing 1.
  • the membrane 8 from a relaxed state (dashed line in FIG Fig. 1 ) in an expanded and tensioned state (solid line in Fig. 8).
  • the device can be triggered if necessary, which is done by an electromechanical release of the previously held energy transfer element 2.
  • the piston 2b is accelerated forward by the applied pressure. Since the membrane initially relaxes, the gas pressure is only slightly reduced, at least in a first movement section.
  • Fig. 2 shows by means of a diagram the relationship between pressure and volume in the gas space 7.
  • the effect of the elastic membrane is a good constancy of the gas pressure, as long as the membrane is in an at least partially tensioned state.
  • the energy transmission element 2 After driving in the fastening means, the energy transmission element 2 is reset by a return spring (not shown) in the starting position and locked. Finally, the refilling of the gas space 7 takes place through the compressor 9.
  • a further piston 11 is provided instead of the rubber-elastic membrane 8, which is movably guided in a rear, shaped as a cylinder 12 portion of the gas space 7 and so forms a to the piston 2b further variable wall portion of the gas space 7.
  • the piston 11 is guided gas-tight against the cylinder 12, wherein the cylinder 12 on which the outside of the piston 11 is freely connected to the atmosphere.
  • the piston 11 is also supported on a plurality of springs 13, which in the present case are coil springs made of metal. In embodiments not shown are torsion, spiral or leaf springs made of metal or Kunsstoff or an elastomer.
  • springs 13 shown schematically, which act depending on the position of the piston as tension springs or as compression springs.
  • the springs 13 can be arranged inside and / or outside the gas space 7. By an at least partial arrangement within the gas space can be saved particularly effective space.
  • the function of the driving device according to the second embodiment is analogous to the first embodiment with the difference that the springs instead of the membrane material form the further mechanical energy storage. It moves the piston 11 increases in pressure in the gas space against the force of the springs 13, so that the gas space increases as in the first embodiment.
