Definitions

  • the object of the invention is a rotary tableting machine with a rotatably mounted die plate in which the upper punch and lower punch are guided, the position of which is controlled by rails and pressure rollers when the die plate rotates, and the holders have for the lower punch against falling out of the die plate if this is dismantled.
  • the holder for the lower punches consists of a brake ring arranged in the die plate, which presses radially on the shafts of all lower punches, so that they do not need to be individually secured.
  • the brake ring is preferably arranged in a circumferential groove of the die plate, which is connected by openings to the holes for receiving the individual punch shafts, which can be achieved in a simple manner by a corresponding depth of the groove.
  • the new type of brake ring acts on all lower punches to the same extent, for example, when replacing the lower punches with others, it is not only necessary to release a large number of safety devices and then re-adjust a large number of safety devices, but only to loosen the brake band which all lower punches are released at the same time and a subsequent tensioning of the brake band for the simultaneous securing of all lower punches.
  • the brake band or the brake ring is provided with a turnbuckle.
  • the inside of the brake ring carries a wear band, which is preferably made of plastic. This prevents wear of the member transmitting a spring pressure, for which an O-ring is preferably provided, on which pressure can be exerted by an external tensioning band.
  • This arrangement also has the considerable advantage that if the wear band is partially worn, the entire brake ring need only be rotated slightly relative to the previous position, so that new wear band sections rest directly on the shafts of the lower punches.
  • FIG. 1 shows a die plate 1 of a rotary tableting machine in section, in which the upper punch 2 and lower punch 3 are guided so as to be height-adjustable for the production of tablets in die holes 4.
  • a tablet is pressed at a pre-printing and main printing station by pre-printing rollers and main printing rollers, between which there are transition rails or guide rails 5 for the lower punches 3, on which these are supported with their heads 6.
  • a brake ring 7 is provided, which is in a the annular disc 15 surrounding the die plate 1 is of square or rectangular cross section. This groove 15 is machined so deep into the die plate that it is connected by elliptical openings 13 to the bores 8 for receiving the lower punches 3.
  • the brake ring 7 engages in these openings 13 with its internal wear band, which preferably consists of an abrasion-resistant plastic.
  • the wear band 9 is under the pressure of an O-ring 10 made of elastic material such as rubber, which is pressed together by a tension band 11, which is provided with a turnbuckle 12 is for opening and closing the entire brake ring 7.
  • a tension band 11 which is provided with a turnbuckle 12 is for opening and closing the entire brake ring 7.
  • the brake ring 7 is also suitable for preventing vibrations of the lower punches, which occur in particular when the pressure rollers not shown in the drawing overflow.
  • the brake ring is self-adjusting, since pressure is continuously exerted on the wear band 9 from the outside by the O-ring 10, which compensates for partial wear. If, on the other hand, the wear band 9 is exposed to greater wear, the brake ring 7 need only be rotated slightly within the groove 15 and then tightened again in order to be able to continue using it over a longer period of time.
