Definitions

  • the invention relates to a method for applying metered amounts of powdered lubricant or separating agent to the claimed surfaces of pressing tools in tableting machines.
  • Rotary tableting machines such as are described, for example, in EP 0 572 816, have a die plate which is driven to rotate about a vertical axis and which contains die holes arranged on a circle.
  • Upper and lower stamps are assigned to the die holes circulate synchronously with the die plate and press powdered material filled into the die holes into the die hole.
  • the stamps are actuated by suitable control cams in order to either open the die holes or to carry out the pressing process.
  • the lower ram When filling in a filling station, the lower ram is in a lower position in the die hole, while the upper ram is at a distance from the die plate.
  • a lubricant or separating agent is required to prevent the tablet from sticking to the pressing tool and excessive friction when the tablets are ejected from the die holes. It is known to use magnesium stearate as the powdery release agent. From DE 38 11 261 it has also become known to use finely divided liquids in gases.
  • Another possibility is to apply the lubricant to the die bore and lower punch, for example by pulsed blowing, as described in DE 38 11 260.
  • a Venturi nozzle is placed directly in front of the punch and the die opening in a tabletting machine.
  • a controlled supply of compressed air ensures that so-called powder packets are ejected onto the stressed surfaces.
  • the known device is relatively complex, in particular with regard to the control and involves the risk that too much sliding material is released, which then undesirably settles on the surfaces adjacent to the die hole and the punch shafts.
  • the known method can only be carried out at relatively low speeds.
  • the invention has for its object to provide a method for applying metered amounts of powdered lubricant and release agent to the claimed surfaces of pressing tools in tableting machines, which requires a minimal amount of lubricant and release agent and works effectively even at very high speeds.
  • the separating agent is continuously blown onto the stressed areas during operation of the tabletting machine, and excess separating agent is continuously sucked off in the areas adjacent to the stressed areas.
  • the separating agent is continuously applied to the punches and into the die bore, so that there is no upper limit with regard to the speed.
  • the amount of lubricant applied to the stressed surfaces is metered and can be kept very small.
  • excess release agent that does not get onto the stressed surfaces and spreads more or less "cloud-like" above the die plate is sucked off, so that they actually affect the stressed Areas or the amount of release agent deposited on the tablet is extremely small, preferably less than 0.02%, based on the substance to be compressed.
  • the lubricant and release agent is used in precisely dosed amounts e.g. swirled in a Venturi nozzle, from which it is then directed to a suitable blowing nozzle in the tabletting machine.
  • a suitable blowing nozzle in the tabletting machine.
  • a kind of swirl chamber effect is achieved in the die hole, enhanced by suction through a suitable suction nozzle.
  • a homogeneous, very low coating of the die wall and the stamp press surfaces is obtained.
  • the reduction of lubricants and release agents in the tablets has the further advantage that the desired tablet hardness can be achieved with a considerably reduced compression pressure. This results in less tool wear and a shorter disintegration time of the tablets. Finally, the reduction of the lubricant and release agent also reduces the corresponding material expenditure for this.
  • So-called double rotary machines are known in which the manufacture of a tablet takes place in half an orbit of the die plates. Accordingly, two filling stations are assigned to the die plate.
  • the possibility of applying lubricant provided in the direction of travel in front of the respectively not used filling device is activated and the possibility of application arranged in front of the used filling station is deactivated. This prevents lubricant from being sprayed onto the material in the die holes.
  • a blowing nozzle is arranged above the die disk at a short distance from it, with a lower nozzle opening aligned with the orbit of the die holes and a nozzle opening aligned with the orbit of the upper punches.
  • the nozzle openings are preferably formed as radially arranged slots which can have approximately the length of the diameter of a die hole.
  • the lower suction opening has a smaller one Distance to the die plate as the lower blow nozzle opening. Excess material can thereby be effectively sucked off from the surface of the die plate in order to prevent material build-up on the die plate.
  • the distance between the upper suction opening and the upper stamp must be set larger so that no material adhering to the upper stamp is sucked off and coating of the stamp shaft is avoided.
  • the blowing nozzle is preferably arranged upstream of the suction nozzle.
  • the single figure shows a section through a die plate in the area of an upper and a lower punch with a device according to the invention.
  • a die plate 10 of a tabletting machine (not shown in the following) can be seen, which has die holes arranged on a circle, one of which can be seen at 12.
  • An upper punch 14 and a lower punch 15 are assigned to the die hole 12. They interact in a known manner with the die plate 10, as described, for example, in EP 0 572 816 and move in the direction of the arrows shown.
  • EP 0 572 816 the die plate 10 of a tabletting machine
  • a stationary blowing nozzle 16 with a lower nozzle opening 18 and an upper nozzle opening 19.
  • the nozzle openings 18, 19 are slot-like and extend radially with respect to the die plate 10, so that they can extend approximately over the diameter of the die hole 12 .
  • the tube-like or box-like nozzle 16 is connected to a Venturi nozzle, not shown, in which gaseous medium, for example air and a pulverulent release agent and lubricant, for example magnesium stearate, are mixed homogeneously.
  • the air-release agent mixture is introduced under pressure into the blowing nozzle 16 and emerges from the upper and lower nozzle openings 19, 18 according to the arrows shown, namely against the pressing surface of the upper punch 14 and against the walls of the die hole 12 and the pressing surface of the Lower punch 15.
  • a suction nozzle 20 is arranged in a stationary manner, one wall of which is formed by the associated wall of the blowing nozzle 16. It is box-shaped in cross section and connected to a vacuum source, not shown. It has an upper suction opening 22 and a lower suction opening 24.
  • the distance A is between the lower The opening 24 and the upper side of the die plate 10 are relatively small, in any case smaller than the distance between the lower nozzle opening 18 and the die plate 10. It is, for example, only 0.5 mm.
  • the distance B between the pressing surface of the upper punch 14 and the nozzle opening 19 or the upper suction opening 22 is somewhat larger and is, for example, 1.5 mm, the same value as the distance between the lower nozzle opening 18 and the die plate 10.
  • the excess mixture of air and powdered release agent is sucked in through the blowing nozzle 20, as shown by the corresponding arrows. Therefore, no substance can be deposited on the die plate 10, not even on the shaft of the upper punch 14.
  • the distances mentioned and the nozzle openings as well as the air quantity and the air pressure or the quantity of the lubricant are matched to one another in such a way that only a minimal quantity the stressed surfaces of the pressing tools is applied and all excess material is removed via the suction nozzle 20. From there, it is taken to a suitable disposal together with the material dust from the tabletting machine.
