Definitions

  • the invention relates to a rotary tableting machine with a die plate rotatably mounted in a housing and connected to a drive shaft, in which upper and lower punches are guided, the position of which is controlled during the circulation of the die plate by stationary curves which are provided with holders.
  • the object of the invention is to significantly improve the relationship between the production times and the downtimes due to a retrofitting and cleaning of the machine parts by a novel design of the tableting machine.
  • the holders of the curves are connected by releasable connecting means to fixed machine parts or housing parts and by drivers to the die plate in such a way that after loosening the connecting means Die plate must be lifted off the drive shaft together with the upper and lower punches and the curves.
  • the rotor must be completely equipped with the punches and curves outside the press and cleaned or converted, while the press can be used by using a similar or the same kit, which was already cleaned before the first kit was removed and equipped for the new production has been.
  • this has the advantage that the largest part of the necessary cleaning and upgrading work is to be carried out in addition to production, ie during this, so that the set-up time and cleaning time are shifted to the manufacturing time.
  • a support arm can be arranged on the housing of the tableting machine for the removal and transport of the structural unit, which, after loosening the connecting means, detects the structural unit, lifts it out of the machine and displaces it in order to use another structural unit.
  • the rotary tablet machine shown in the drawing has a rotatably mounted die plate 6, which is provided with a multiplicity of dies 11, which are arranged evenly distributed over the circumference.
  • tablet material is pressed together to produce the tablets by lower ram 7 and upper ram 8, which are adjustably held in associated bores in the die plate.
  • the lower punches 7 are advanced by a rail-like control cam 9 with control slots 50 and the upper punches 8 are delivered by a control cam 10 with a slot 50.
  • the die plate 6 is mounted in a fixed housing 4.
  • a drive shaft 1 is provided which is rotatably held in the housing 4 by bearings 2 and 3.
  • This to Drive shaft 1 is connected by driver 5 to the die plate 6, which are designed in the manner of a feather key.
  • a clamping screw 30 is provided, which extends from above through the die plate 6 down into the shaft 1, to which it is connected by a thread 31.
  • the head of the screw 30 is supported on a clamping sleeve 87 which is screwed to the die plate 6.
  • the die plate 6 rotates and with it the lower and upper punches 7 and 8 around the axis of the drive shaft 1, the punches arrive at the pressing station 96 shown on the right in FIG. 1, at which they pass through a lower pressure roller 20 and an upper pressure roller 21 are set in the position in which a single tablet is pressed within the pressing chamber 80.
  • the curve 9 is connected by a screw 84 to a curve holder 14, which is connected to the machine housing 4 in a fixed but detachable manner by means of screws 40.
  • the curve 10 for the control of the upper punch 8 is connected to a curve holder 15 by screws 84.
  • This curve holder 15 is also connected to the fixed machine housing 4 by screws 40, which are not visible in FIG. 1, because they lie in the plane which is perpendicular to the plane of the drawing as a section plane.
  • the cylinder 42 is detachably connected to the fixed housing by screws 40.
  • the brackets 14 and 15 for the control cams 9 and 10 connected to them have bores 18 in which there are pins 12 which extend in annular grooves 19 of the die plate 6.
  • This arrangement makes it possible to lift the die plate 6 together with the lower punch 7 and the upper punch 8 and the control cams 9 and 10 as a common structural unit from the drive shaft 1 and to exchange them for a similar structural unit.
  • the shaft 22 of this pressure roller is preferably arranged such that it can be adjusted in height, so that the pressure roller 21 is first raised slightly until the assembly can be raised slightly and then swung out sideways. With this lifting, however, it should be avoided that the stamps located in the area of the printing station 96 and not held there by the curves 9 and 10 fall out of the die plate. Therefore, supports 60 and 61 are provided in this area for holding the heads of the lower punch 7 and upper punch 8.
  • the pivotable support arm provided for the transport of the complete structural unit is designed telescopically in order to be able to offset the structural unit in a straight line when pivoting about the axis 98.
  • a support arm instead of such a support arm, of course, other constructions are also possible, such as rails or devices that can be operated automatically.
