Definitions

  • the present invention relates to a fastener-feeding device for a power driven tacker referred to in the preamble of claim 1.
  • Fastener supply device for power operated Eintreibella, such. B. screwdrivers have to attach to a substrate on a head part, the leadership of fasteners such. As screws, before and during the driving operation.
  • This headboard can, for. B. be part of a fastener magazine or a fastener transport device, which can be placed on a flange of a tacker.
  • the disadvantage here is that the jaw elements are usually completely opened only by the head of the screw widened with respect to the shaft, wherein the forces necessary for the complete opening of the jaws are of the diameter and the geometry depend on the screw heads.
  • the opening behavior of the jaw elements is therefore different for different screw types.
  • the object of the present invention is to provide a fastener supply device for a power driven tacker, in which, regardless of the type of fastener to be driven in a uniform opening behavior of the jaw members and a good guidance of the screws is achieved.
  • actuating means are arranged on the jaw elements, which can be actuated via control means on the first unit for pivoting the jaw members from the closed position to the open position.
  • the first unit is designed as a housing.
  • the control means are formed as inner surfaces of the housing.
  • the control means can be provided without additional components in a technically simple manner.
  • the actuating means are designed as projections, which in each case protrude in a direction away from the tool axis of the jaw elements.
  • the actuating means can thereby interact in a simple manner with the control means on the first unit when the second unit is pushed in a driving operation in the first unit.
  • the projections of the first unit have facing ramps to dome-shaped rising flanks, whereby tilting or entanglement and a high expenditure of force during pivoting of the jaw elements via the control means is avoided.
  • FIGS 1 to 3 show a generally designated 10 fastener supply means according to the invention which is releasably fixed with a coupling portion 14 on a flange 41 of a power driven Eintreib mars 40 only indicated in the figures.
  • the partially reproduced tacking device is designed as an electrically operated screwdriver.
  • the fastener supply device 10 is designed as a screw magazine with integrated transport mechanism 32 for the transport of a screw magazine strip 30.
  • In the fastener-supply device 10 designed as a screw driving tool 13 is guided, which can be rotationally actuated via the power driven tacker 40.
  • the fastener supply device 10 has a first assembly 11, which includes the coupling portion 14 and which is formed here as a guide housing, and a second unit 19, which is displaceably held on the first unit 11, on.
  • the second structural unit 19 carries the transport mechanism 32 and guides the screw magazine strip 30.
  • the second structural unit 19 has a head part 20 which can be attached with an end face 18 to a substrate U.
  • two jaw elements 21, 22 are arranged laterally of a tool axis A defined by the driving tool 13.
  • These jaw elements 21, 22 are pivotably held on pivot bearing 25 on the head part 20 and have at their end face 18 facing the ends of jaws 23 which in a closed position 16, which is shown in FIG. 1, a fastening means 31, such as a screw, can hold and lead.
  • the jaws 23 of the jaw members 21, 22 do not necessarily have to be seamless abut each other, but may have a small distance from each other depending on the shaft thickness of the fastening means 31, which they lead.
  • the jaw elements 23 each have a part of a guide channel 29 for guiding the fastening means 31, through which the fastening means 31 can be passed.
  • the jaw elements 21, 22 are elastically acted upon by spring elements 26, which are supported on the one hand on the jaws 23 and on the other hand on projections 27 on the head part 20 in the direction of the closed position 16.
  • actuating means 24 designed as projections are arranged, which in each case protrude from the jaw elements 21, 22 in a direction away from the tool axis A.
  • the first unit 11 facing flanks 15 of the actuating means 24 are formed ramping or dome-shaped rising.
  • control means 12 are arranged, which are formed by inner walls of the unit 11 and against which the actuating means 24 are movable with their flanks 15.
  • the second unit 12 is moved into the first unit 11 in the direction of the arrow 33.
  • the actuating means 24 run on the jaw members 21, 22 with their ramps or dome-shaped rising flanks 15 against the control means 12 on the first unit 11 and are offset by this contact in the direction of the tool axis A.
  • the jaw elements 21, 22 pivot from their closed position 16 into an open position 17, in which the jaws 23 no longer guide and release the fastening means 31.
  • the jaws 23 are then located at a greater distance to the tool axis A, as in its closed position 16. The process of moving apart of the jaws 23 takes place before the fastener 31 is completely screwed into the substrate U.
