Definitions

  • the invention relates to an attachment machine for buttons, hooks, eyes or the like. with a lower punch and a movable upper punch, which is attached to the lower end of a first plunger, with which a second plunger, which is telescopically displaceable, cooperates, which is driven by the machine drive, e.g. is applied via a rocker arm, the two plungers being connected to one another in a pressure-locking manner via an attenuator.
  • Attaching machines of this type have become known through obvious prior use. They are used to attach buttons, hooks, eyelets, trademarks or the like. Applications on clothing, leather goods, etc. The applications can be in one part or in several parts. In principle, the attachment is done by riveting between the lower stamp and the upper stamp. Depending on the resistance to deformation of the articles to be fastened and above all on the thickness of the carrier material (fabric, leather or the like), the compressive force with which the upper punch acts on the lower punch must be set. In a known machine, this is done by adjusting the ram stroke. To do this, a rocker arm on a control cam or the pivot point of a rocker arm must be adjusted. Because of the changed stroke, it is then necessary to assign Adjustment of the tappet or stamp-side receptacles for the individual parts of the articles to be attached is also new. This is complex and should be avoided with the invention.
  • the invention is therefore based on the object, starting from a piecing machine of the type outlined in the preamble of claim 1, to make it easier to adjust the pressure force with which the upper punch presses against the lower punch.
  • the damping member consists of a damping adjustable shock absorber comprising cylinder and piston with piston rod, the maximum stroke of which is greater than the tappet stroke.
  • the ram stroke can always be kept constant regardless of the materials used. In any case, it is smaller than the maximum stroke of the shock absorber, which consequently cannot be stopped.
  • the damping is adjusted accordingly depending on the desired pressure force. If a high pressure is required, the damping is adjusted accordingly. If, due to the tolerance being exceeded, the riveting process is not completed when the highest set pressure force occurs, the shock absorber acts as an overload regulator.
  • the attenuator does not consist of one adjustable disc spring package column.
  • the subject of the invention is always a damped coupling of the telescopically displaceably arranged two plungers. This has the further advantage that the riveting process itself takes place with a smooth course.
  • the piston rod of the shock absorber is preferably connected to one plunger and the cylinder to the other plunger in a pressure-resistant and tensile-proof manner.
  • the oscillating movement initiated on the second tappet is therefore transmitted to the other tappet via the shock absorber arrangement both on the outward stroke and on the return stroke, taking into account the possible play of movement between the piston rod and the cylinder.
  • the cylinder of the shock absorber can be screwed into an internal thread section of the second tappet with an external thread section.
  • the shock absorber has an adjusting ring which can be actuated from the outside through a window arranged in the first tappet.
  • An adjusting pin can also be attached to the adjusting ring, which differs from one of the minimal damping corresponding end position can be pivoted slightly up to the other end position corresponding to the maximum damping.
  • a first plunger 13 is mounted so that it can be raised and lowered in the vertical direction.
  • an upper punch 14 is attached.
  • a pair of pliers 15 is assigned to it, with which a button or button top is temporarily held and fed to a lower punch, not shown.
  • the stamp level designated 16 in the rest position is always the same, regardless of the pressure force to be adjusted to match the different materials. As a result, the feed for the buttons or button tops to the pliers 15 never needs to be changed.
  • a second plunger 17 is telescoped longitudinally slidably added.
  • This second plunger 17 is in a tension and pressure connection with a drive bracket 18, which can be attached, for example, to a rocker arm of the machine drive.
  • the first plunger 13 is connected to the second plunger 17 via a shock absorber 19.
  • the cylinder 20 of the shock absorber 19 is provided with an external thread section 21 which is screwed into a corresponding internal thread 22 of a hollow section of the second plunger 17.
  • the piston rod 23 dips into a blind hole 24 of the first plunger 13 and is fastened here by means of a screw, of which only the center line 25 is indicated.
  • Reference numeral 32 schematically indicates an anti-rotation device between the plungers 13 and 17.
  • the damping of the shock absorber 19 can be changed with the aid of an adjusting ring 26, on which there is a radial adjusting lever 27.
  • the setting acts on a throttle inside the hydraulic shock absorber 19.
  • the mode of operation of the shock absorber 19 is best understood from the description of a work cycle.
  • the rest position of the machine is shown in Fig. 1.
  • the drive tab 18 is moved down from its highest position. Because no reaction force initially acts on the first plunger 13, the second plunger 17 takes the first plunger 13 downward with the movement via the shock absorber 19.
  • the damping is adjusted tion force of the shock absorber 19 by means of adjusting ring 26 or adjusting lever 27.
  • a window is provided in the arrangement area of the adjusting ring 26 within the tubular section of the first plunger 13, which opening is indicated schematically in FIG. 1 and designated by 31.
  • a plier opener 29 in conjunction with a machine-fixed stop 28 is used for clock control of the pliers 15 articulated on the pliers holder 30.
  • the pliers 15 opens (Fig. 2) as soon as the button or the like. sits on the material.
  • the upper punch 14 then moves further downward relative to the pliers 15 to produce the riveting against the lower punch, not shown.
