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. This transmission of the movement of an actuating rod and the exertion of the force of the rotating spring on the locking elements advantageously lead to the fact that the diameter of the locking unit can change.
- 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.
- the individual locking elements of the locking unit in the extended state cooperate with projections within the recesses of the carrier plate of the rotary press, wherein these projections are preferably designed so that they allow a secure attachment of the pressure roller station in the extended state of the locking elements. It is preferred for the purposes of the invention to refer to these projections preferably as a clamping collar or clamping flange, wherein said terms are used synonymously.
- a recess in the carrier plate preferably has such a projection in the upper area facing the pressure roller station, the projection preferably representing a region of the reduced diameter recess. Within the meaning of this invention, this region may also be referred to as bottleneck. 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.
- the locking unit is designed to be height-adjustable, wherein the height adjustment by means of an actuating rod is realized, the center, or centrally is arranged in the annular locking unit.
- "Height adjustable” in the sense of this invention means that the locking unit is designed to be movable in particular in the vertical direction and can be moved up or down.
- the spatial direction "down" in the context of this invention from the viewpoint of the pressure roller station preferably for a movement of the locking unit in the direction of the carrier plate of the rotary press, when the pressure roller station is usually arranged on the carrier plate of the rotary press.
- such a movement is preferably referred to as a "downward movement" of the locking unit or of the actuating rod.
- the locking unit passes into the recesses of the carrier plate by a downward movement of the holding device.
- the spatial direction "upwards” in the sense of this invention preferably denotes an upward movement of the holding device into the interior of the pressure roller station, ie preferably in the direction of the pressure rollers preferably belonging to the pressure roller station. This is especially true when the holding device is present in the recesses of the carrier plate.
- the movement of the locking unit that is, its height adjustment, realized by means of an actuating rod.
- the previous comments on the spatial directions are preferably related to the Druckrollenstation. It is preferred that, from the perspective of the carrier plate, the spatial direction "upward” is characterized by a movement in the direction of the pressure roller station and / or the rotary press. The upper side of the carrier plate is thus preferably facing the rotary press and the pressure roller station.
- the actuating rod is arranged centrally or centrally in the pressure roller station.
- Centered in the sense of this invention means that the actuation axis is arranged substantially axially symmetrically about a central axis of the pressure roller station, wherein the term “substantially” is not unclear to the average person skilled in the art because he knows that pressure roller stations usually have a rectangular or circular base surface, wherein for such basic shapes usually a mean axis of symmetry can be determined.
- the actuating rod has a diameter tapering towards the lower end of the actuating rod.
- the actuating rod comprises an upper and a lower region, the upper region in particular having a circular base surface which corresponds to the inner diameter of a pressure roller station.
- the inner region of the pressure roller station which preferably serves to receive the actuating rod and whose diameter preferably corresponds to the diameter of the actuating rod, is preferably formed by a hydraulic cylinder, this hydraulic cylinder preferably comprising a two-part piston consisting of an inner and outer piston includes. It is preferred that the movement of the actuating rod is realized by means of at least this hydraulic connection.
- the actuating rod consists of a lower portion, which initially consists of a tapered portion and merges into a region of constant radius towards the lower end of the actuating rod, wherein this constant radius of the lower portion is smaller than the diameter of the Operating rod in the upper area.
- the diameter of the locking unit is maximum in a first position and minimal in a second position, wherein the diameter of the locking unit is variable by means of an actuating rod.
- the locking elements of the locking unit are pressed by the actuating rod to the outside. It is preferred that this happens when the region of the actuating rod is in contact with the locking elements, which has the largest diameter of the actuating rod. 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. It is preferred that the locking elements even in the unlocked state engage in the projection of the recess of the carrier plate.
- the unlocked state is, for example, in FIG. 3 shown.
- the locking elements are gradually relieved by a preferably stepwise raising of the actuating rod.
- it is provided in a first position that the pressure exerted by the locking elements, for example on the inner wall of the recesses in the carrier plate, is reduced.
- the pressure roller station in this position, can be rotated about its own axis, wherein a displacement or removal of the Druckrollenstation from the recess, for example, effectively prevented that the locking unit is still below a clamping collar in the recess of the support plate.
- a second position in the sense of this invention is preferably provided after an upward movement of the actuating rod when, at the level of the pressure pins arranged between the locking elements and the actuating rod, the area of the actuating rod is present which has a reduced diameter compared to the upper region of the actuating rod , It is preferred that in this second position no direct contact between the actuating rod and the pressure pins of the locking elements is given, so that the locking elements are preferably no longer against the inner walls of the Recesses are pressed. It is particularly preferred that in this position, the locking elements are released and pressed by the spring force of the rotating spring in a position with a minimum diameter.
- this position is referred to in the sense of the present invention second position or "released" position of the locking unit.
- Tests have shown that the pressure roller station in this position, the inventive holding device can be moved out of the recesses of the support plate surprisingly simple and without unwanted mechanical contact.
- the locking unit has its minimum diameter in the released state, which corresponds in particular to the diameter of the constriction formed by the projection.
- This state of the locking unit with minimum diameter is preferably referred to as dissolved state and is in FIG. 4 shown.
- the locking elements of the locking unit in the first position are pressed against an inner wall of the recess of the carrier plate. It is preferred that the inner walls of the recess are formed by a straight wall. In the first position or spread position of the locking elements, the fastening of the pressure roller station is preferably carried out by the spreading pressure, which exert the locking elements on the inner wall of the recess.
- the inner wall of the recess is provided, for example with a projection, wherein the inner diameter of the recess in the region of this projection is smaller than in the remaining region of the recess and this projection in the context of the invention preferably referred to as a clamping collar or clamping flange becomes. It was quite surprising that the provision of protrusions within the recesses enabled effective attachment of the pressure roller station within the recess.
- the diameter of the locking unit in the second position is smaller than the diameter of the recesses of the carrier plate. It is preferred that the locking elements leave the spread position (first position) due to the spring force exerted by the rotating spring. This advantageously reduces the Diameter of the locking unit and the locking elements are no longer in contact with the inner wall of the recess.
- the holding device is completely in the interior of the pressure roller station. It is preferred to refer to this position in the sense of the invention as a "rotor change position". Preferably, the holding device in this position does not protrude beyond the lower end of the pressure roller station, whereby advantageously a displaceability and pivotability of the pressure roller station is ensured. It was completely surprising that a holding device with a locking unit can be made so compact that it can be completely absorbed by the pressure roller station and terminates flush with the pressure roller station in the lower area. This is advantageously achieved by the cooperation and engagement of the components of the holding device with the receiving pressure roller station, whereby it is achieved that the holding device can be introduced in the limited space available in the pressure roller station.
