Definitions

  • the invention relates to a coin press, with a machine frame, an embossing drive for plunger and embossing die, an ejector embossing die, against which the embossing die can be pressed with the interposition of the embossing blank and to which part is yieldable, a drive for the ejector movement of the ejector embossing die and a device for feeding the Embossing blank and for removing the finished part.
  • Such a coin stamping press is known from EP-A-0 101 590.
  • the embossing drive takes place by means of a triangular lever known per se, driven by a crankshaft via a central bearing, which is articulated with its rear rocker arm bearing on a handlebar and via this on the frame side and with its front rocker arm bearing via a push rod on the tappet.
  • This oscillation system is designed such that pivot points and articulation points in their positions relative to one another enable a circular movement which is at least approximated for the push rod in its pivot point on the tappet at the time it passes through the rear dead center.
  • the arrangement mentioned makes it possible to control the linear movement of the plunger in such a way that there is sufficient time to remove a minted coin from the minting tool between two minting processes and to insert a new coin blank.
  • a disadvantage of the known coin minting press is that the described embossing drive takes up a relatively large amount of space, especially when it is to be used in presses which pressures of more than 200 t should exert on the coin blank. Since these forces also act on the embossing drive, the individual components of the same must be appropriately dimensioned so that the individual components must be relatively large.
  • the present invention is therefore based on the object of eliminating the present disadvantages of the prior art, in particular providing a coin embossing press which has the smallest possible height and less play within the embossing drive.
  • Another advantage of the coin embossing press according to the invention is the reduction in the play of the embossing drive, since it has significantly fewer joints than is the case with known coin embossing presses, so that the overall game, which is composed of the game in the individual joints, is reduced . This reduction in play is particularly noticeable with frequent load changes, as is the case with fast-running coin minting presses.
  • a shaft 3 is provided in the machine frame 1 of a coin press 2, which is driven by a motor 6 via a flywheel 4 and a belt transmission 5.
  • a double cam 7 is placed, which is part of a cam mechanism 8.
  • the cam mechanism 8 also has a rocker arm 9, which is provided with two arms, on each of which a cam roller 10 is attached, the cam rollers 10 abutting the double cam disc 7 and scanning them.
  • the rocker arm 9 is connected in an articulated manner to a knee joint transmission 12 via a pressure plate 11.
  • the knee joint transmission 12 has an upper pressure plate 13 and a lower pressure plate 14, which are connected to one another at one point and are articulated together with the pressure plate 11.
  • the upper pressure plate 13 is articulated at one end to the plunger 15 of the minting press 2, the plunger 15 being linearly displaceable in a suitable plunger guide 16.
  • the other end of the lower pressure plate 14 is articulated to the machine frame 1.
  • the plunger in turn is connected to a plunger tool 17 arranged above the plunger 15, into which the coin blanks are inserted from a feed drum 18 via a feed station 19 into a turret plate 20, which is provided with a stepping gear mechanism.
  • An upper tool 21 is provided above the plunger tool 17 for simultaneously embossing the front and back of the coin.
  • FIGS. 2 to 4 show in an enlarged representation the combination of the cam mechanism 8 and the knee joint mechanism 12 already described in connection with FIG. 1.
  • rocker arm 9 has at its end facing the knee joint mechanism 8 a further bolt 23, wherein the pressure bracket 11 is articulated on the bolt 23, which, as already mentioned, establishes a connection to the knee joint mechanism 12.
  • Both the side of the pressure plate 11 facing away from the cam mechanism 8 and also one end of the upper pressure plate 13 and the lower pressure plate 14 are connected to one another in an articulated manner on a bolt 24.
  • a tool clamping 27 for an embossing die 28 is provided on the plunger 15.
  • plunger 15 moves in accordance with the movement diagram shown in FIG. 5.
  • the tappet 15 carries out an embossing stroke in a range from approximately 60 ° crank angle to 300 ° crank angle.
  • the plunger 15 is not raised at all, so that the plunger 15 also during this time all the tools attached to it stand still and during this time a new coin blank can be brought into the minting station of the coin embossing press by the feed drum 18, the feed station 19 and the turret plate 20 (see FIG. 1). A new stamping process can then take place.
  • FIG 6 schematically shows an overall view of the gear combination used comprising the cam mechanism 8 and the knee joint mechanism 12.
  • the dash-dotted lines illustrate the deflected position of the knee joint mechanism 8.
  • the double cam disc is graphically divided into three areas, with the solid line showing the movement of the plunger 15 upwards, i.e. when an embossing stroke is carried out, while the dashed line symbolizes the movement of the plunger 15 downwards, i.e. the return stroke, and where the dash-dotted line represents the area in which the plunger 15 maintains its position, ie the area in which a minted coin is removed and a new coin blank is inserted into the minting tool.
  • the overall height of the entire coin press 2 can be significantly reduced in a simple manner.
  • the arrangement described has the advantage that in the main power flow of the embossing drive, that is, from the machine frame 1 via the Bolt 24 through the knee joint gear 12 to the plunger 15, compared to the prior art, significantly fewer articulation points are contained, so that a better power transmission is possible.
  • the arrangement described can, for example, reduce the working height of the minting press at a pressure of 300 t from approximately 1900 mm to approximately 1400 mm.
