Definitions

  • the invention relates to a wrapping device for fasteners according to the preamble of claim 1.
  • a knock-in device of the type mentioned at the outset is known, in which the chopping knife is connected to the punch and detaches the protruding empty end of the holding belt on each knock-in stroke.
  • This end of the tether then falls onto the surface of the workpiece and, if it is not removed, can be pressed into the workpiece from the mounting surface of the cylinder base, so that this surface is damaged.
  • the impact ram is subject to high acceleration forces, so that the attachment between the impact ram and the chopping knife is very susceptible to failure, and breaking off the chopping knife can lead to unpleasant interruptions in work.
  • the invention is therefore based on the object of providing an impact device of the type mentioned at the outset in which the empty tether can be reliably and reliably removed.
  • the chopping knife can be operated both manually and by means of a compressed air piston connected to it, which in turn can be triggered by a suitable, manually actuated feeler valve.
  • a pressure impact piston 2 with impact ram 3 is slidably mounted in a housing 1.
  • a cylinder base 4 is connected to the housing 1, in the ejection channel 5 of which the fastening means, i.e. e.g. the nail 6 is provided and from there can be driven into a workpiece, not shown, with the ram 3.
  • the nails 6 are connected to a nail strip 6 by a holding belt 7 and are stored in a drum magazine 8 in a spiral roll. From there, they are fed to the discharge channel 5 via a conveyor shaft 9 by means of a conveyor device 10 and made available for the next stroke.
  • a guide sleeve 15 is fastened to the cylinder base 4 in the vicinity of the outlet slot 13 with screws 14, in which a chopping knife 16 is slidably mounted.
  • the cutting edge 17 of chopping knife 16 moves perpendicular to the feed shaft 9 via the outlet slot 13.
  • a compression spring 19 is arranged in a longitudinal bore 18 of the chopping knife 16 and pushes the chopping knife away from the outlet slot 13 in the rest position. It is held in its rest position by a pin 20 connected to it, which engages in a groove 21 of the guide sleeve 15.
  • the guide sleeve 15 is surmounted by an actuating pin 22, with which the wrapping device thus hits a suitable surface, e.g. can be pushed against the workbench or workpiece that the chopping knife 16 moves in the direction of the conveyor shaft 9 and detaches the empty tether 7.
  • the chopping knife 16 can be connected to a compressed air piston 23 which is displaceably mounted in a compressed air cylinder 25 connected to the guide sleeve 24.
  • Compressed air cylinder 25 is connected via a compressed air line 26 to a tactile valve, not shown, by means of which the chopping knife can be triggered again after being actuated by hand.
