Definitions

  • the invention relates to a tabletting stamp having the features according to the preamble of claim 1.
  • So-called rotary presses are widely used for the production of tablets, particularly in the field of pharmacy or food supplements, in which tabletting punches interact with dies in horizontally arranged tables rotating about a vertical axis of rotation.
  • the tabletting punches are used as upper and lower punches, which follow a revolving movement synchronously with the rotary table and carry out controlled lifting movements.
  • One rotation of the table corresponds to one work cycle, at the beginning of which a die is closed from below with a lower punch. Powder is now poured into the matrix opening from above.
  • the associated upper punch is then lowered.
  • the powder in the die is pressed into a tablet by a pressing process between the upper and lower punches.
  • the fully pressed tablet is ejected by a joint lifting movement of the upper and lower punches, whereupon the aforementioned work cycle begins again.
  • a punch head of the respective tabletting punch is used, which is opposite at the free end of the punch shaft is arranged to the pressing surface.
  • Such a punch head has a circumferential surface, a central mirror surface with a rounded transition area on the side facing away from the shank, and a retraction surface on the side facing the shank.
  • the punch head runs in a cam track, which, depending on the direction of movement, introduces compressive or tensile forces into the tabletting punch via the punch head.
  • the upper and lower punches are initially positioned against one another by means of the cam tracks mentioned in such a way that they enclose a certain amount of powder between their pressing surfaces within the die.
  • the pressing movement now performed with a small pressing stroke is no longer generated by the cam track, but by a pressure roller, which hits the punch head in an entry zone of the transition area and from there rolls over the mirror surface. After the pressing has taken place, a retraction movement takes place by means of the aforementioned cam track.
  • the punch heads are subject to high loads and are therefore exposed to a certain amount of wear. On the one hand, this applies to the interaction between the punch head and cam track, which can become problematic, especially when the punches are stiff. In particular, however, the transition area and the mirror surface are exposed to high surface pressures under the action of the pressure roller. In addition, it has been shown that a certain relative sliding movement is also unavoidable under the high surface pressure mentioned. This is particularly pronounced when non-rotatable axial guidance of the punch is required relative to the turntable or to the associated die. In such a case, the punches rotate with the turntable, while the stationary pressure roller does not perform such a rotary movement. During the rolling process, this also leads to a proportionate sliding movement between the punch head and the pressure roller, which promotes wear under the effect of the high surface pressure.
  • a tableting stamp according to the preamble of claim 1, in the head of which a pressure-receiving element is inserted and held by a pair of magnets.
  • One of the magnets is designed as an electromagnet and its polarity can be reversed.
  • a worn pressure-receiving element can be ejected and replaced with a new one.
  • a tabletting stamp is also described, the stamping head of which is provided with a shock-absorbing insert element.
  • the insert element is loosely inserted with the interposition of a shock-absorbing and self-lubricating liner.
  • the stamp does not have a fall-out safety device, as this function is taken over by the stamp head guide of the entire machine when installed.
  • the invention is based on the object of further developing a generic tableting stamp in such a way that the operating forces that occur can be transmitted reliably and with little wear with a simplified structure.
  • the punch head has a head body and, separately therefrom, a central pressure-receiving element, the head body is rotatably and in particular integrally connected to the shaft.
  • the peripheral surface and the retreat surface are formed on the head body.
  • the pressure-receiving element is rotatably supported in the head body, and the central mirror surface is formed on this pressure-receiving element.
  • the design according to the invention means that a rotatable bearing is only present where pressure forces are introduced from the pressure roller into the punch head.
  • a heavy-duty and structurally simple axial thrust sliding bearing can therefore be used here between the head body and the pressure receiving element; the high pressing forces can hereby be transferred easily and safely.
  • the pressure-receiving element can rotate freely under the action of the pressure roller and thus reduce the sliding friction between the punch head and the pressure roller to a minimum.
  • the pressure roller cannot introduce any torques into the stamps designed according to the invention.
  • the stamps remain essentially free from torsional moments. Any existing feather key guides are relieved, which reduces wear and improves positioning accuracy.
  • the main body of the head which is firmly connected to the shank, continues to exert the function of introducing force from the guide cam track.
  • the tensile forces are introduced at this point when the punch is pulled out of the die, without a rotary bearing being used here.
  • the connection between the head body and the shank allows high tensile forces to be transmitted, even if it is difficult to move, without fear of damage.
  • non-rotatable and in particular one-piece connection of the head body with the shank does not mean that the rest of the punch has to be made in one piece overall.
  • stamps constructed in several parts are also possible, provided that the pressure-receiving element is designed separately from the main body of the head and is mounted such that it can rotate with respect to it.
  • the tabletting die has an axial thrust bearing for the rotatable mounting of the pressure-receiving element in the main body of the head and, separately therefrom, a safety device against falling out.
  • an axial contact surface is formed on the head body and, corresponding thereto, a circumferential annular flange lying against the axial contact surface is formed on the pressure receiving element.
  • a holding magnet is arranged between the head body and the pressure-receiving element to form the fall-out safety device.
  • sufficiently high holding forces can be achieved with little technical effort, with the holding force or axial prestressing force applied by the magnet readily allowing free rotary movement of the pressure receiving element.
  • a receiving space with a floor is formed in the head body, with the holding magnet lying flat on the floor of the receiving space, and with a gap remaining between the holding magnet and the pressure-receiving element. This ensures that a rotational movement of the pressure receiving element is not transmitted to the holding magnet and that the mechanically sensitive holding magnet is not exposed to any frictional forces. In addition, this reduces the axial magnetic holding or prestressing force to such an extent that the pressure-receiving element can be pulled out with a magnet attached directly to its mirror surface and replaced if necessary.
  • the tabletting die has a safety element to form the safety device against falling out, which engages in a circumferential annular groove of a pin of the pressure-receiving element.
  • a mechanical, form-fitting safety device is formed which, on the one hand, generates high holding forces and, on the other hand, allows a free choice of material, even without taking potential magnetic properties into account.
  • the spatial extent of the pressure-receiving element is limited to the central, planar mirror surface, while the remaining sections of the stamping head are formed on the head body.
  • at least a first section of the rounded transition area is also expediently formed on the rotatable pressure-receiving element.
  • the entry zone of the transition area for a pressure roller is formed completely on the pressure receiving element. The result of this is that the pressure roller does not come into contact with the main body of the head during its entire interaction with the tabletting stamp, but only touches the rotatably mounted pressure-receiving element.
  • the pressure-receiving element can therefore bring about compensation during the entire pressure loading phase by means of suitable, automatically brought about rotational movements.
  • FIG. 1 shows a perspective view of the head area of a tabletting stamp 1 according to the invention. It comprises a shaft 2, at one axial end of which a punch head 3 is arranged, and at the opposite axial end of which, not shown here, there is a pressing surface for pressing a tablet. On its side facing away from the shank 2 , the punch head 3 has a central mirror surface 28 that is perpendicular to the longitudinal axis 26 .
  • the stamping head comprises a head body 4 and, separately from the body 4, a central pressure-receiving element 5.
  • the head body 4 is non-rotatably connected to the shank 2, for which purpose a one-piece design of the shank 2 and the head body 4 is provided in the preferred exemplary embodiment shown.
  • the main head body 4 and the pressure-receiving element 5 are positioned coaxially to the longitudinal axis 26 , the pressure-receiving element 5 being mounted in the main head body 4 so as to be rotatable about the longitudinal axis 26 .
  • the pressure-receiving element 5 is freely rotatably movable relative to the assembly of the shaft 2 and the head body 4 .
  • the central mirror surface 8 is formed entirely on the pressure-receiving element 5 and does not extend into the head body 4 .
  • the tabletting stamp 1 and the pressure roller 24 are part of a rotary tablet press, not shown in detail, with the tabletting stamp 1 revolving together with a press table, also not shown.
  • the unit consisting of the shaft 2 and the head body 4 of the tableting punch 1 can be moved axially, but is mounted in a rotationally fixed manner relative to the said press table. With each rotation of the press table, the tabletting stamp follows a circular path and rotates around its longitudinal axis 26 as well. In addition, it is thereby moved revolving relative to the locally fixed pressure roller 24 according to an arrow 29 .
  • the shank 2 immediately adjacent to the punch head 3 initially has a diameter-reduced section 2 ′, from which the punch head 3 widens radially.
  • the largest diameter of the ram head 3 is larger than the diameter of the shank 2.
  • the ram head 3 has a cylindrical circumferential surface 6 running around it.
  • the punch head 3 is provided with a conical retraction surface 7 which extends from the tapered section 2 ′ of the shank 2 to the peripheral surface 6 of the punch head 3 .
  • the central mirror surface 8 next to the central mirror surface 8 is a circumferential, rounded transition area 20 which extends from the peripheral surface 6 to the mirror surface 8 .
  • a parting line 25 is formed between the head base body 4 and the pressure-receiving element 5 rotatably mounted therein, which in the transition area 20 runs in a circle around the longitudinal axis 26 and divides the transition region 20 into a first section 21 associated with the pressure-receiving element 5 and a second section 22 associated with the head base body 4 . Accordingly, in addition to the central mirror surface 8 , at least the first section 21 of the transition area 20 is also formed on the pressure receiving element 5 . However, it can also be expedient for the rounded transition area 20 to be formed completely on the rotatable pressure-receiving element 5 .
  • a run-in zone 23 is formed by a part of the transition area 20, at the edge of which the pressure roller 24 hits the punch head 3 according to a dashed line and also lifts off from it again on the opposite side.
  • the pressure roller 27 rolls along the entry zone 23 and along the mirror surface 8 on the punch head 3 . Since the transition area 20 and also the central mirror surface 8 are located completely on the pressure-receiving element 5 , direct contact between the tabletting stamp 1 and the pressure roller 24 takes place only on the pressure-receiving element 5 . There is no direct contact with the head body 4 .
  • the pressing lifting movement of the tabletting stamp 1 in the direction of arrow 30 generated by the pressure roller 24 is therefore brought about solely by the rolling movement of the pressure roller 24 on the pressure-receiving element 5, with the pressure-receiving element 5 moving during the entire rolling process and during the entire contact with the pressure roller 24 in a rotating evasive movement can rotate freely and automatically about the longitudinal axis 26, whereby undesirable sliding friction between the pressure roller and the surface of the stamp head 3 is reduced to a minimum.
  • the pressure roller 24 does not transmit any axial force, any rotational movement and consequently also no frictional forces to the structural unit made up of the shaft 2 and the head body 4.
  • FIG. 3 shows a perspective exploded view of the tabletting die 1 according to FIG Figures 1, 2 .
  • the shaft 2 and the head body 4 are designed in one piece, with a cylindrical receiving space 15 open towards the head side being formed coaxially with the longitudinal axis 26 in the interior of this structural unit.
  • the opening of the receiving space 15 is surrounded by an annular contact surface 10 which is perpendicular to the longitudinal axis 26 .
  • the annular contact surface 10 is in turn surrounded by a peripheral wall of the head body 4 in the shape of a pot.
  • a holding magnet 14 has a cylindrical shape, is positioned coaxially to the receiving space 15 and has a diameter that matches the receiving space 15 .
  • the pressure-receiving element 5 On its side opposite the mirror surface 8 , the pressure-receiving element 5 has a cylindrical pin 13 .
  • An annular flange 11 extends in the radial direction between the pin 13 and the peripheral wall of the pressure-receiving element 5 perpendicularly to the longitudinal axis 26 , the dimensions of which correspond to the contact surface 10 of the head base body 4 .
  • the diameter of the pin 13 corresponds to the diameter of the holding magnet 14, so that the pin 13 and the holding magnet 4 can be inserted into the receiving space 15 without any significant play, but without jamming. All three parts, namely the structural unit made up of the shaft 2 and the head body 4, the pressure-receiving element 5 and the holding magnet 14 are designed as bodies of revolution with the common longitudinal axis 26 .
  • the pressure receiving element 5 with its larger peripheral surface held centered in the cup-shaped peripheral wall of the head body 4 .
  • the pin 13 protrudes into the receiving space 15 .
  • the annular flange 11 of the pressure receiving element 5 lies flat on the contact surface 10 of the head body 4 .
  • a lubricant (not shown), a sliding disk or a suitable coating can be introduced in between.
  • an axial thrust bearing 9 is thereby formed overall, which allows a rotational movement of the pressure-receiving element 5 relative to the structural unit made up of the head base body 4 and the shaft 2 under axial pressure loading.
  • Said thrust bearing 9 can only absorb compressive forces, but not tensile forces.
  • a safety device 12 is therefore provided, by means of which the pressure-receiving element 5 is prevented from falling out of the head base body 4 .
  • the holding magnet 14 already mentioned above is positioned between the head base body 4 and the pressure-receiving element 5 in relation to the axial direction of the longitudinal axis 26 .
  • the receiving space 15 has a flat base 16 which is perpendicular to the longitudinal axis 26 and on which the holding magnet 14 lies flat.
  • a magnetically attractable material is selected for the structural unit consisting of the shaft 2 and the head body 4 , as a result of which the holding magnet 14 designed as a permanent magnet adheres magnetically to the base 16 .
  • the pressure-receiving element 5 also consists of a magnetically attractable material, so that the pressure-receiving element 5 is attracted in the axial direction by the holding magnet 14 in such a way that its annular flange 11 rests against the contact surface 10 under axial pretension and cannot fall out.
  • a gap 17 remains between the holding magnet 14 and the end face of the pin 13, which allows a free rotary movement of the pressure receiving element 5 relative to the head body 4 solely under the influence of the axial thrust bearing 9 and without friction against the holding magnet 14.
  • the Figures 5 and 6 show a variant of the arrangement according to the exploded view or in longitudinal section 3 and which is not part of the invention.
  • a different form of fall-out safety device 12 is used: On the peripheral surface of the pin 13, a circumferential annular groove 19 is formed.
  • a bore 28 is introduced into the tapered section 2 'of the shaft 2, the bore axis of which runs tangentially to the cylindrical peripheral surface of the receiving space 15 and is at the same axial height as the annular groove 19 in the assembled state of the pressure receiving element 5.
  • the embodiment is consistent with the Figures 5 and 6 with those after the Figures 1 to 4 match.
  • an encapsulation and/or seal in the area of the pressure-receiving element 5 and its fall-out safety device 12 can also be considered in order to increase the possibilities of washing or cleaning improve.
