  • the tableting material is pressed into openings and/or bores in the matrix disk to form compacts, whereby the matrix disk can be part of a rotating rotor.
  • the rotor rotates about a rotor axis, the rotor axis preferably being designed perpendicular to a preferably flat rotor surface and/or rotor underside and the rotor axis preferably being arranged centrally, i.e. centrally, within the rotor.
  • chamber filling shoes In order to fill the tabletting material into the openings and/or bores, filling devices are used, with so-called chamber filling shoes or motor-operated filling devices being described in the prior art, for example.
  • Chamber filling shoes are characterized in that the tableting material reaches the area of the matrix disk due to gravity.
  • an outlet pipe can be used for this, with the outlet of the tabletting material
  • controlled with a gate valve or a rotary valve and/or can be limited.
  • the use of chamber filling shoes is particularly advantageous when tabletting material with good flow and filling properties is to be pressed into compacts and/or tablets.
  • impellers can be arranged, with which the tableting material is transported to the die bores. In this way, a good filling result can be achieved even for pressed material that flows poorly.
  • the filling devices known from the prior art can be fastened within the tableting machine, for example, with the aid of a metal frame and/or a filling shoe clamping plate.
  • the filling shoe clamping plate can preferably also be referred to as a filling shoe clamping plate, with the terms "filling shoe clamping plate” and "filling shoe plate” in the sense of the invention preferably being used as a generic term for both terms.
  • the filling shoe clamping plate is adjusted to the matrix disk of the rotor of the tabletting machine in such a way that the filling shoe plate is aligned plane-parallel to the matrix plate and is at a distance from the matrix disk.
  • This distance can be, for example, in the range of 0.1 - 0.3 mm.
  • the filling device is 0.1 - 0.3 mm higher than the die plate of the rotary press.
  • This distance can be adjusted using adjusting means and/or adjusting elements, with a particular concern of the present invention being to simplify and optimize the setting and/or adjustment of the filling shoe clamping plate and/or the filling device, the previous setting and/or adjustment being carried out by
  • a particular concern of the present invention being to simplify and optimize the setting and/or adjustment of the filling shoe clamping plate and/or the filling device, the previous setting and/or adjustment being carried out by
  • the installation of conventional filling devices in tableting machines is very time-consuming and labor-intensive.
  • proper adjustment of the filling shoe plate requires a lot of experience, patience and sensitivity on the part of the operator.
  • Both the frame of the chamber filling device and the housing of the motor-operated filling device can be attached to the filling shoe clamping plate, the holder of which is preferably attached to the machine housing or the machine base in a stationary manner relative to the rotating rotor of the rotary press.
  • the underside of the filling devices When assembled, the underside of the filling devices must under no circumstances touch the rotating die disk, otherwise the die disk and/or the filling shoe plate could be damaged. If the filling devices are attached to the filling shoe clamping plate, the underside of the filling device must face the die disk preferably be both aligned plane-parallel and have a uniform distance from the matrix plate of, for example, 0.1 - 0.3 mm.
  • the filling shoe clamping plate can be connected to the tabletting machine, for example with the aid of clamping and/or adjusting screws, the connection being realized on the tabletting machine side by an adjusting plate of a holder, for example of the metal frame.
  • adjustment elements such as spindles, screws and/or lock nuts can be used.
  • the disadvantage of using such conventional adjusting elements as part of the arrangement and fastening of the filling device within the tabletting machine is that these conventional adjusting elements can influence each other in their effect.
  • Setting and/or adjusting the filling shoe clamping plate is not easy and is also very time-consuming, since when the position of one adjusting element is adjusted, the positions of the other adjusting elements are often automatically adjusted as well.
  • the adjusting elements ensure, in particular, adjustments of the filling shoe clamping plate and/or the filling device in different spatial directions, these directions preferably being referred to as parameters in the sense of the invention.
  • a filling shoe clamping plate has an optimal setting and/or adjustment in all but one parameter. If one of the mutually influencing adjustment elements is then adjusted in order to optimize the setting of the filling shoe clamping plate and to make it more favorable for all parameters, it can happen that the setting for the other parameters is worsened and in the sum and in the overall view of all parameters worse result is obtained than before. It is an object of the present invention to avoid the occurrence of such situations.
  • a further concern of the present invention is that an optimization of the filling shoe position relative to the matrix plate can be carried out, particularly when the tableting machine is running.
  • the term “filling shoe position” preferably includes the adjustment and/or fastening of the filling shoe clamping plate and/or the filling device.

  • the filling shoe plate is very well adjusted or there is an optimal distance between the underside of the filling device and the die plate. This means in particular that the filling shoe plate has a uniformly small distance from the rotating die plate. An adjustability of the filling shoe position relative to the die plate while the tableting machine is in operation cannot be achieved by conventionally fastening the filling device or the filling shoe clamping plate with the adjustment elements mentioned.
