Definitions

  • the invention relates to a device for the production of compacts, preferably a tablet machine, according to the preamble of claim 1.
  • a filling shoe for a tablet machine has become known in which the filling shoe is arranged on a base in a small portion above the die plate.
  • a vertical plate of the base has a vertical slot through which a Locking screw is guided, which cooperates with a threaded bore of a plate of the filling shoe to adjust the filling shoe by hand at a predetermined distance from the die plate.
  • a filling shoe has become known, which can be brought by means of servo motors in a predetermined position on a die table of a powder press. The filling shoe rests on the die table and is moved back and forth between a filling position and a waiting position.
  • the object of the invention is to remedy the aforementioned maladministration.
  • the dosage should be further improved and the occurrence of black spots on the surface of the compact or tablet should be minimized.
  • the bottom plate of the filling shoe is mounted on a height-adjustable base via a motor arranged in the machine frame.
  • a measuring device is provided, via which the distance between the bottom plate of the filling shoe and the surface of the rotating die plate is measured.
  • an output device for the measured values can serve here.
  • the gap width can be ensured by means of a control loop in which the gap width is adjustable as a controlled variable, even if height differences occur during the rotational movement of the rotating die plate.
  • FIGURE shows a schematic schematic diagram of an embodiment of the present invention.
  • a machine frame 12 In a machine frame 12 is a die plate 14 via a motor, not shown here in the direction of arrow a in stepwise rotation displaceable. By this stepwise rotation each a not shown here compression chamber (die) is brought to receive the contents to be pressed in their receiving position.
  • the receiving position is defined by a stationary filling shoe 16, over which the product to be pressed is introduced.
  • a filling shoe 16 may be used, for example, a well-known in the art Rhackeriel spallschuh.
  • the filling shoe 16 is on a base plate 18 on a sock! 20 is mounted so that it is positioned in the manner shown in the figure to the rotating die plate 14. In this partially overlapping position results in a gap 22, the width of which depends on the distance between the underside of the bottom plate 18 of the filling shoe 16 and the surface of the rotating die plates 14.
  • a high-precision servo motor 15 in the double arrow direction b is adjustable. In this case, the rotational movement of the servo motor 15 can be transmitted by any gear on the base 20.
  • the servo motor 15 and the transmission are designed so that a Setting the width of the gap 22 to 100th mm is possible
  • the width of the gap 22 can be measured here in a manner not shown in detail in the figure by means of a measuring device and represented graphically by means of an output device.
  • the respectively optimally set values can be detected reproducibly.
  • the values can also be stored in an electronic memory.
  • the width of the gap 22 can also serve as a control variable of a control loop. In this way, an optimal distance between the filling shoe 16 and the die plate 14 can be adjusted, based on empirical values for certain feedstocks to be pressed in a machine otherwise known in its design.
