Definitions

  • the invention relates to a rotary tableting machine with a rotatably mounted die plate, in which the upper and lower punches are guided, the position of which is controlled in pressure stations by pressure rollers, which are height-adjustable and have a drive for them.
  • the aim is to design the training so that it is possible to retrofit a machine for the subsequent manufacture of another type of tablet as well as for cleaning individual machine parts as quickly as possible so that the downtimes are only short.
  • the die plates can be removed from the side of the machine together with the lower and upper punches for replacement.
  • Such is, however, hampered by the pressure rollers which are provided at the printing stations, in particular when two printing stations are provided, as is already customary in high-performance machines.
  • each printing station is subdivided into a pre-printing station and a main printing station, each of which has an upper pressure roller and a lower pressure roller, so that a total of eight pressure rollers are present in two diametrically opposite printing stations.
  • the object of the invention is to design a printing station in such a way that its essential components can be detached from the machine as a structural unit or structural units, so that, if necessary, they can also be exchanged for other uniform units and thereby shorten the downtimes of the machine or also to simplify the complete removal of a die plate.
  • a pressure roller is mounted in a bearing block which is connected to the housing of its drive.
  • a bearing block of the pressure roller is preferably provided with a receiving flange which is slidably held in a guide of the housing by the drive for the pressure roller, so that, for example for disassembling the die plate, only a partial displacement of the pressure roller for releasing the die plate is possible during its dismantling is.
  • the pre-pressure and main pressure stations can be designed uniformly and independently of one another and can be detached from the tabletting machine as structural units, ie they can be serviced at a remote location, so that in the meantime they have to be replaced by identical ones Parts.
  • the rotary tableting machine shown in the drawing has a rotating die plate 2, which is provided with a plurality of die holes 4 which are evenly distributed over the circumference and in which tablets are pressed.
  • the compression takes place by means of upper punches 10 and lower punches 12, which are guided in bores of the die plate 2, at the so-called pressing stations.
  • the two press stations are divided into a pre-printing station and a main printing station.
  • Each printing station has an upper pressure roller 6 and a lower pressure roller 7, each of which is held on a shaft 8.
  • the shafts 8 are adjustable in height by a drive which is detachably fastened to the fixed machine housing 14.
  • a pressure roller 6 is held in a bearing block 18, which is provided with a linear guide 20, which is adjustable in height on a column 22.
  • the column 22 is supported by a receiving flange 24 which is detachably connected to the drive housing 28 for the height adjustment of the pressure roller 6.
  • the drive housing 28 is provided with a rail-like guide 30 which cooperates with a rail-like, approximately dovetail-shaped counter-guide at the bottom of the receiving flange such that the receiving flange 24 together with the column 22, the linear guide 20, the bearing block 18 and thus the pressure roller 6 radially adjusted to the die plates can and can be completely detached from the drive housing 28 according to the arrow 50.
  • a partial radial adjustment is advantageous if the die plate 2 together with the upper punches 10 and the lower punches 12 is to be pivoted out of the machine for the purpose of cleaning or replacing them, since in such a case the pivoting-out movement is not impeded by a pressure roller 6. which is in their working position.
  • a complete separation of the pressure roller 6 with its bearing block 8 and its linear guide 20 from the drive housing takes place when the pressure roller with its storage is to be processed, for example for the purpose of maintenance. After such a complete detachment, there is also the possibility of detaching the drive housing 28 with its components as a self-contained structural unit from the tabletting machine and, if necessary, of exchanging it for the same structural unit in order to save time.
  • the components of the drive in the housing 28 include a height-adjustable spindle 38 for the adjustment of the pressure roller 6.
  • the adjustment is carried out via a worm wheel 34 which interacts with a worm 36.
  • the adjustment can be carried out manually or mechanically.
  • the spindle 38 carries a force measuring device 40 with a pressure mushroom 42, on which the bearing block 18 is supported directly or indirectly.
  • the countless cable connections for measuring and controlling the device are connected to the housing 28 via a limit switch 44.
  • the adjusting spindle 38 is raised according to FIG. 4 so that the receiving flange 24 can be pulled out of the guide 30 together with the bearing block 18 according to arrow 50.
