Definitions

  • the invention relates to a rotary press with at least one pressure roller station which can be fastened on a carrier plate, and to methods for fastening and releasing the pressure roller station.
  • concentric presses have a rotary driven rotor which carries a plurality of pairs of stamps, each pair of stamps being formed by an upper punch and a lower punch, which are adjustable relative to each other.
  • the rotor comprises a die plate in which on a circular ring at regular intervals die openings are provided, in which the upper and lower punches either interact directly, or have the sleeve-shaped configured inserts, which are referred to as dies.
  • dies In these dies or die openings to be processed, or, for example, to a tablet to be pressed material is filled by means of a filling device.
  • the pressing force is transferred according to the illustrated procedure, which is used in particular for the production of a so-called single-layer tablet, by means of the pressure rollers on the pressing tools, in particular the upper and lower punches are referred to as pressing tools.
  • rotary presses are known in which these pressure rollers are present separately from one another, for example at the top on a head piece and at the bottom on a carrier plate in the base of the rotary press.
  • a disadvantage of this separate arrangement of the two pressure rollers is that the pressing forces arising during the pressing process are transmitted directly into both the upper and the lower machine housing.
  • the machine housing of the rotary press for example, consists of a machine base, on which the support plate for the lower pressure roller is located, as well as a head piece, on which the upper pressure roller is attached.
  • the head piece and the machine base are connected to each other, for example, by 2 to 4 Eckholme, the head piece, corner posts and the support plate in the base of the rotary press in the separate arrangement of the pressure rollers must be made very solid and high cost of materials to withstand the pressure forces. This leads to a high weight of the rotary press and high acquisition costs for a potential customer.
  • pressure roller stations include, for example, support columns, which are arranged outside the pitch circle of the rotatable rotor of the rotary press.
  • the support columns contain inside guide and adjustment means for the upper and lower pressure roller, as well as position measuring and pressure measuring systems.
  • the pressure rollers are located in a working position of the pressure roller station exactly on a rotor pitch circle, so that the upper pressure roller acts on the Oberstkov- and the lower pressure roller on the lower punch heads.
  • Modern rotary presses are characterized by the fact that starting from a basic equipment for the production of single-layer tablets by adding appropriate additional modules conversion of the base press can be made to the effect that two-layer, three-layer, or even jacket core tablets can be pressed.
  • additional modules may be, for example, printing stations or pre-press stations.
  • the object of the present invention is to provide a rotary press and method for fastening and releasing a pressure roller station of a rotary press, which do not have the shortcomings and disadvantages of the prior art and in particular a cost, low maintenance and easy-to-use attachment allow pressure roller stations at predetermined positions on the support plate of a rotary press.
  • a rotary press in particular for the production of tablets, with at least one pressure roller station, said at least one Druckrollenstation comprises a holding device and a support plate of the rotary press has at least one recess for receiving the holding device of the Druckrollenstation.
  • a pressure roller station can be provided which comprises a holding device, so that in particular only as many holding devices for the operation of a rotary press have to be provided as printing stations are used. This is advantageously achieved in that the holding device is part of the pressure roller station and is integrated in it.
  • the holding device according to the invention is a clamping device for fixing the pressure roller station in recesses in the carrier plate of the rotary press. It is further preferred that the holding device is present in a production position at least partially disposed in the recesses of the carrier plate.
  • the production position is preferably the position occupied by the pressure roller station when the rotary press is operated in order to produce tablets.
  • the holding device is present in a rotor changing position completely within the pressure roller station, wherein as a rotor change position preferably such a position of the pressure roller station is called, which occupies the Druckrollenstation when a rotor change of the rotary press takes place.
  • the invention represents a departure from the hitherto technically usual, because the experts had previously assumed that holding devices be part of the support plate have to. It was completely surprising that a pressure roller station can be provided which has so much free volume in the lower area facing the carrier plate that a holding device can preferably be received completely inside the lower area of the pressure roller station.
  • the recesses of the carrier plate are formed by openings and / or bores whose diameters correspond to the diameter of the holding device of the pressure roller stations.
  • the recesses are suitable for receiving the holding device of the pressure roller station.
  • the fastening means for example clamping devices, are located regularly in the interior of the recesses within the carrier plate of the rotary press. This is a disadvantage mainly because these provided in the support plate of the rotary press fixtures are complex in construction and / or require their own media supply supplies, resulting in an undesirable weakening of the support plate.
  • innovations in the field of development of the carrier plates of rotary presses are prevented because the space available in the area of a carrier plate is considerably reduced by the presence of a large number of clamping devices.
  • the holding device has locking elements, which in their entirety form an annular locking unit with a variable diameter.
  • the locking unit preferably comprises 2 to 20 locking units.
  • the selection of this number is not an arbitrary choice, but corresponds to the result of previous experiments, which have shown that a locking unit with preferably 2 to 20 locking elements is surprisingly easy to manufacture and to an unexpected stability of attachment of the pressure roller station to the support plate contributes.
  • the locking elements comprise a circumferential spring.
  • the circumferential spring preferably exerts a force inwardly on the locking elements of the locking unit.
  • the direction "inwards” means that the locking elements are pressed in the direction of a central axis of the pressure roller station FIG. 4 shown.
  • the locking element is advantageously pressed into a groove which leads annularly around the interior of the holding device and surrounds pressure pins, by which the movement of an actuating rod is transmitted to the locking elements.

  • the variability of the diameter of the locking unit according to the invention surprisingly allows a particularly stable interaction of the holding device of the pressure roller station with the recesses of the support plate, whereby not only an innovative type of attachment is provided, but a comparison with conventional fastening mechanisms attachment that withstands surprisingly high loads ,
  • the individual locking elements by means of pressure pins, which transmit the up and down movement of a variable-diameter actuating rod on the locking elements, to the outside can be driven, so that the diameter of the locking unit, for example, increases.

It was completely surprising that a variable diameter locking unit could be provided which, in its untensioned condition, has a diameter smaller than the throat diameter, whereby the retaining device can be simply and easily inserted into the recess in the support plate. It was further completely surprising that after the introduction of the holding device in the recess, the diameter of the locking unit can be increased by the interaction of an actuating rod with the locking elements so that the holding device is no longer removed, for example by pulling upwards, from the recess of the carrier plate can be.

It is preferred that the actuating rod cooperate with pressure pins which push the locking elements of the locking unit to the outside.
  • This position is preferably referred to in the sense of the present invention as the first position or spread position of the locking unit.
  • a so-called "unlocked” state is preferably characterized in that the actuating rod is also pressed vertically upward, preferably by the upward movement of a pneumatic piston, whereby an unlocking of the locking elements is achieved.
