Description

DEVICE FOR CARRYING A COMPONENT OF A TABLETING MACHINE, AND THE USE OF IT AND A METHOD OF ADJUSTING A POSITION OF A COMPONENT OF A TABLETING MACHINE

In a first aspect, the invention relates to a device for carrying a component of a tablet machine, the device comprising as components an upper part, an intermediate element and a lower part. In further aspects, the invention relates to a tabletting machine comprising a described device and a method and a use of the device for setting a position of a component of a tableting machine. With the proposed device, in particular the filling shoe clamping plate of a tablet machine and thus preferably the position of the filling device above the die plate, preferably at the machine device, but also during operation of the rotary press, can be easily, quickly and reproducibly adjusted so that the loss of material is minimal.

It is known in the prior art that pellets or tablets can be produced with tableting machines, which are formed, for example, as rotary presses. In a rotary tablet press, the tablets are produced in the openings or bores of a die plate by compressing the tablet material from which the tablet will later be made between an upper punch and a lower punch to form a pellet. The tableting material is pressed into pellets in openings and / or bores in the die plate, it being possible for the die plate to be part of a rotating rotor. It is preferred in the sense of the invention that the rotor rotates around a rotor axis, the rotor axis preferably being 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.

In order to fill the tableting material into the openings and / or bores, filling devices are used, so-called chamber filling shoes or motor-driven filling devices, for example, being described in the prior art. Chamber filling shoes are characterized in that the tableting material reaches the area of the die plate due to the force of gravity. For example, an outlet pipe can be used for this, with the outlet of the tableting material being regulated, for example, with a gate valve or a rotary valve and / or can be limited. The use of chamber filling shoes is particularly advantageous when tableting material with good flow and filling properties is to be pressed into pellets and / or tablets.

In motor-operated filling devices, for example, impellers with which the tableting material is transported to the die bores can be arranged. In this way, a good filling result can also be achieved for poorly flowing press material. The filling devices known from the prior art can, for example, be fastened inside the tablet machine with the aid of a metal frame and / or a filling shoe clamping plate. Depending on the specific fastening method, the filling shoe clamping plate can preferably also be referred to as a filling shoe clamping plate, the terms “filling shoe clamping plate” and “filling shoe plate” in the context of the invention preferably being used as a generic term for both terms. Usually the filling shoe clamping plate is adjusted to the die plate of the rotor of the tablet machine so that the filling shoe plate is aligned plane-parallel to the die plate and is at a distance from the die plate. This distance can be in the range of 0.1-0.3 mm, for example. In particular, the filling device is 0.1-0.3 mm higher than the die plate of the rotary tablet press. This distance can be adjusted with adjusting means and / or adjusting elements, whereby it is a particular concern of the present invention to simplify and optimize the setting and / or adjustment of the filling shoe clamping plate and / or the filling device, whereby the previous setting and / or Adjustment by installing conventional filling devices in tablet machines is very time-consuming and labor-intensive. In particular, proper adjustment of the filling shoe plate requires a lot of experience, patience and a sure instinct on the part of the operator.

Both the frame of the chamber filling device and the housing of the motor-driven filling device can be attached to the filling shoe clamping plate, the holder of which is preferably fixed to the rotating rotor of the rotary press on the machine housing or the machine base. In the assembled state, the bottom of the filling devices must never touch the rotating die plate, otherwise the die plate 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 plate preferably be aligned both plane-parallel and have a uniform distance from the die plate of, for example, 0.1-0.3 mm.

The filling shoe clamping plate can, for example, be connected to the tableting machine with the help of clamping and / or adjusting screws, the connection being realized on the part of the tableting machine by an adjusting plate of a holder, for example the metal frame. In addition, adjustment elements such as spindles, screws and / or lock nuts can be used. The disadvantage of using such conventional adjusting elements in the context of the arrangement and fastening of the filling device within the tableting machine is that these conventional adjusting elements can mutually influence one another in their effect. In other words: The setting and / or adjustment of the filling shoe clamping plate is not easy and also very time-consuming, since when adjusting the position of an adjusting element, the positions of the other adjusting elements are often automatically adjusted. The adjusting elements ensure, in particular, adjustments of the filling shoe clamping plate and / or the Füllvorrich device in different spatial directions, these directions in the sense of the invention being preferably referred to as parameters.

It can happen that a filling shoe clamping plate has an optimal setting and / or adjustment in all parameters except for 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 as a result and in total and in the overall view of all Parameter a worse result is obtained than before. It is an object of the present invention to avoid such situations from occurring.

Another concern of the present invention is that the filling shoe position can be optimized with respect to the die plate, especially when the tablet machine is running. In the context of the invention, the term “filling shoe position” preferably includes the setting and / or fastening of the filling shoe clamping plate and / or the filling device. With the ability to adjust the filling shoe clamping plate and / or the filling device during operation In addition, the tableting machine can advantageously minimize the loss of material that necessarily occurs during an adjustment or readjustment. The extent of the loss of material can, for example, be checked optically by performing a visual check of the surface of the die plate. If this appears bright like a mirror and in particular no powder and no material streaks can be seen on the die plate, 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 is at a uniformly small distance from the rotating die plate. A divisibility of the filling shoe position relative to the die plate while the tableting machine is in operation cannot be achieved by the conventional fastening of the filling device or the filling shoe clamping plate with the aforementioned adjusting elements.

It would therefore be desirable to be able to provide a device which eliminates the disadvantages mentioned and allows an easily manageable and precise setting of the filling plate relative to the die with little construction effort. In the known state of the art, there are no adequate solutions to date:

DE 41 33 761 A1 proposes a holder for the spatial alignment of an object and comprises a lower receiving block, a central pivot plate and an upper holding plate. The contact surfaces between the swivel plate and the holding plate are preferably each configured as sections of a cylinder jacket with respect to two right-angled axes. By loosening or tightening mirror-symmetrical adjusting screws, tilting or swiveling movements in the order of magnitude of 1/100 mm around the respective axes should be enabled. A use of the holder for aligning components of a tablet press is not disclosed.

US 650644 A discloses a pivotable or tiltable holder in a machine vice. For this purpose, an attachment on a work table is proposed with a lower plate and concave or convex segments lying on top of one another. The angle of inclination can be adjusted by means of a screw with a spiral thread become. CN 205 364 626 U also does not describe any use of the holder for aligning components of a tablet press.

CN 201 645 875 U describes a cleaning device for pressing smaller tablets with a measuring head whose outer diameter is matched to the die holes to be cleaned. The cutter head is attached to a guide rod which is connected to a handle via a universal joint. The joint is a universal joint. A component of the tablet press to be cleaned itself is not aligned by the joint.

CN 201 645 875 U discloses a three-point fine adjustment for a filling device in a rotary press, which is intended to enable a more precise alignment of a lower surface of the filling device with the die plate. For this purpose, a holder is suggested, which is supported on three support columns. Each of the support columns has fine adjustments and convex or concave spherical surfaces at the upper end. During installation, the filling device with its base plate is attached to the three support columns. This is intended to achieve a 3-point fine adjustment which allows the angle of inclination and height to be adjusted in relation to the die plate. The disadvantage is an increased construction effort and the necessary setting of three separate support columns.

It is therefore the object of the present invention to provide a device which does not have the disadvantages and deficiencies of the prior art. One object of the invention is in particular to simplify the setting and / or adjustment of the filling shoe clamping plate and / or the filling device. Another task of the invention is that the filling shoe clamping plate and / or the filling device can be readjusted and / or adjusted while the tablet machine is in operation, to minimize the loss of material when setting the distance between the die plate and the filling device, as well as an optical one Possibility to test the functioning and / or the quality of the filling shoe position.

Description of the invention:

The object is achieved by the features of the independent claims. Advantageous embodiments of the invention are described in the dependent claims. According to the invention, a device for carrying a component of a tablet machine is provided, the device comprising as components an upper part, an intermediate element and a lower part. The device is characterized in that the upper part, the intermediate element and the lower part are arranged one above the other and the contacting surfaces of the components are each designed to be corresponding, so that the upper part and the intermediate element are designed to be slidable to one another in a first spatial direction and the intermediate element and Lower part are designed to be slidable to one another in a second spatial direction. The spatial directions are defined by two pivot axes lying essentially perpendicular to one another in one plane or preferably coincide with these.

In the context of the invention, it is particularly preferred that the component of the tableting machine is a filling shoe clamping plate, a filling shoe clamping plate and / or a filling device. In the following, therefore, a filling shoe plate or a filling device is predominantly referred to. But it is also preferred that other than these components of a tablet machine can be attached to the proposed device. For the purposes of the invention, it is preferred that the device is suitable for carrying and / or receiving the component of the tableting machine. In the context of the invention, it can also be preferred that the component is attached to the tablet machine with the device or that the proposed device forms a storage device for the component of the tablet machine. Preferably, the device can also be viewed as a holding device for a tableting machine component, the device preferably being set up to set and / or adjust the location and / or position of the component of the tableting machine in space. This ability results in particular from the proposed structure of the device and the slidable zueinan the designed arrangement of the components of the device, the movability of the components to each other is made possible in two different spatial directions, which is in particular due to the corresponding shaping of the one facing Surfaces of the components is guaranteed. The tablet machine can particularly preferably be a rotary press. In a particularly preferred aspect, the invention therefore relates to a tabletting machine comprising a rotor, a die plate with die cavities, a filling device for filling the die cavities and a device for carrying the filling device, the device comprising an upper part, an intermediate element and a lower part as components , wherein the upper part, the intermediate element and the lower part are arranged one above the other and the contacting surfaces of the compo nents are each designed correspondingly, so that the upper part and the intermediate element are designed to be slidable to one another in a first spatial direction and the intermediate element and lower part in a second spatial direction zuei nander are designed to slide and the filling device is installed on a filling shoe clamping plate, which is attached to the upper part of the device and an adjustment and / or adjustment of the filling shoe clamping plate relative to the Matri center disc allowed.

In the context of the invention, it is particularly preferred that the proposed device supports the filling shoe plate and / or the filling device in two intersecting pivot axes, the pivot axes preferably being essentially perpendicular to one another. For the purposes of the invention, it can be particularly preferred that a center of gravity of the component of the tableting machine is preferably located below the point of intersection of the pivot axes. This preferably leads to the fact that the component of the tabletting machine does not follow the inclination of its surroundings. It was completely surprising that the proposed device can be used to provide a device with which the adjustment is made much easier and with which the filling shoe position can be set with respect to the die plate, especially when the tablet machine is running.

For the purposes of the invention, it is preferred that the upper part of the device has a surface and a cylindrical underside, the upper side of the upper part being in particular flat. A flat top side is preferably characterized in the sense of the invention in that the flat top side is suitable for carrying and / or receiving a plate-shaped object. For example, the flat top of the upper part of the proposed device can preferably be used for the filling shoe plate to be placed on it. Incidentally, the person skilled in the art knows what a flat top is like. For the purposes of the invention, it is preferred to use the terms “top side” and “surface” synonymously. It is further preferred in the context of the invention that the upper part has a cylindrical underside. In the context of the invention, this preferably means that the lower region of the upper part of the device is designed like a partial region of a round cylinder. The bottom is preferably formed by a curved outer wall. In addition, the lower outer edges of the upper part can run in the shape of an arc of a circle or represent a section of a circle. In other words, the underside of the upper part of the device is crescent-shaped. This implies that there is an outward curvature of the preferably cylindrical underside, with an “outward curvature” in the sense of the invention preferably being referred to as a “convex” configuration of the underside.

It is within the meaning of the invention that a virtual pivot axis can be derived from the cylinder-shaped underside of the upper part of the device. This pivot axis can preferably coincide with the first spatial direction in which the upper part and the intermediate element of the device can be designed to slide relative to one another. In the context of the invention, this preferably means that the upper part of the device is designed so that it can move about this pivot axis, the pivot axis preferably representing an axis of rotation of this movement.

This movement of the upper part of the proposed device is preferably referred to as movement “in a first spatial direction” within the meaning of the invention. In a preferred embodiment of the invention, the pivot axis can be derived from the partially cylindrical shape of the upper part when, for example, a virtual central axis is placed through the partial cylinder that has been supplemented to form a complete cylinder. It is particularly preferred that this virtual pivot axis can be derived from the preferably partially circular arc-shaped outer edge of the underside of the upper part of the device or from the preferably cylindrical outer wall of the upper part. It is preferred in the context of the invention if this pivot axis, which is determined, for example, by the shape of the underside of the upper part of the device, is associated with a y-axis and / or this pivot axis coincides with the first spatial direction.

It is preferred that this movement of the upper part is supported by the shape of the upper side of the intermediate element, the intermediate element preferably having a cylindrical upper side which is in particular designed to accommodate the lower side of the upper part of the proposed device. This ability is described in the sense of the invention in that the top of the intermediate element and the bottom of the upper part are designed to correspond to one another.

In the context of the invention, it is particularly preferred that the shape of the underside of the upper part corresponds to a shape of the surface of the intermediate element. This advantageously makes it possible for the upper part and the intermediate element to be designed such that they can slide relative to one another in a first spatial direction. In the context of the present invention, the intermediate element preferably has an inwardly curved upper side, which in the context of the invention is preferably referred to as a “concave” upper side or curvature, the preferred correspondence between the upper side of the intermediate element and the lower side of the upper part is achieved by the concave design of the top of the intermediate element and the correspondingly convex design of the bottom of the upper part.

According to the invention, it is further preferred that the upper side of the intermediate element and the lower side of the upper part are designed similarly to the components of a ball joint, whereby in this analogy the intermediate element represents the joint socket and the upper part represents the joint head, the upper part is preferably set up to move in the cavity of the Zwischenele element, in particular to rotate therein. It is particularly preferred in the context of the present invention, the pivot axes in the To lay the die table level. It is most preferred that one of the pivot axes intersects the rotor axis.

It is further preferred that the intermediate element has a cylindrical top side and a cylindrical bottom side. It is particularly preferred that the upper side of the intermediate element is concave and the lower side of the intermediate element is convex. It is particularly preferred that the bulges do not run at the same distance from each other and, for example, reflect the shape of evenly sagging railroad tracks, but it is much more preferred in the context of the invention that the respective lowest points of the preferably concave top and the preferably convex from formed underside are arranged rotated by essentially 90 ° to each other. If the preferably concave upper side and the preferably convex underside of the intermediate element were theoretically supplemented to form round cylinders, the central axes running through the middle of the cylinders would preferably run perpendicular to one another and lie in a spatial plane.

It is preferred in the context of the invention that the shape of the underside of the intermediate element corresponds to a shape of the surface of the lower part. Since it is achieved by that the intermediate element and the lower part are designed to be slidable to each other, the movement to each other preferably represents a Drehbe movement, which in the context of the invention is preferably a Dre hung in a second spatial direction, which is preferably with a x-axis of the device coincides. The x and y axes are preferably formed essentially perpendicular to one another, the x and y axes preferably lying in a plane which is, for example, parallel to and / or identical to the plane of the die table of the tableting machine. It is preferred in the context of the invention that this x-axis represents a pivot axis for the movement of the intermediate element in the lower part of the device, the pivot axis or its spatial arrangement preferably being derived from the preferably circular shape of the upper side of the lower part of the device is. For example, the pivot axis can be thought of as a virtual central axis through the partial cylinder that is complemented to form a complete cylinder, that of the underside of the intermediate element is formed and which preferably corresponds to the top of the bottom of the device.

For the purposes of the invention, it is preferred that the axes of the cylinders enclose an essentially right angle with one another in a first spatial direction and in a second spatial direction. In the context of the invention, the pivot axes are preferably also referred to as “axes of the cylinder surfaces”, “axes of rotation” or “cylinder axes”. It is preferred in the context of the invention that the device enables a component of a tablet machine to be pivoted, preferably about the pivot axes.

These swivel axes are preferably virtual swivel axes, the term “virtual swivel axis” in the context of the invention preferably being understood in such a way that the swivel axes do not necessarily exist against each other and are designed to be visible and / or tangible. The invention preferably comprises at least one, preferably virtual, pivot axis, and in the context of the invention the presence of two or three pivot axes may also be preferred. It is most preferred if there are two pivot axes.

According to the invention, it is particularly preferred that the component of the tableting machine to be pivoted and / or adjusted can be brought into an advantageous position by rotating the components of the device, preferably regardless of whether other components or other components are in this position term obstacles to the attachment of an actually existing "axis" - for example in the form of another component of the tablet machine - stands in the way. This is particularly preferred when the component of the tableting machine to be swiveled and / or to be adjusted is formed by a clamping plate for filling devices. For the purposes of the invention, it is particularly preferred to place the pivot axes in the plane of the die table, in particular in such a way that one of the pivot axes intersects the rotor axis. In the context of the invention, this preferably means that the pivot axis which intersects the rotor axis is preferably arranged radially to the rotor, with another pivot axis preferably perpendicular this and approximately tangential to a pitch circle of the die plate can be arranged.

In a preferred embodiment of the invention, the mutually touching surfaces of the upper part, the intermediate element and the lower part are designed correspondingly to one another so that the pivotable upper part is assigned a pivot axis which corresponds to a first spatial direction and the intermediate element is pivotable about a pivot axis which corresponds to the second spatial direction. Such pivot axes can be ensured, for example, as described above, by appropriate coordination of corresponding, cylindrical upper and lower sides of the components.

In this way, it is advantageously possible to set an inclination of the filling shoe clamping plate, an inclination in particular about a radial and / or a tangential axis, preferably based on the rotor, being able to be set. The ability to adjust the inclination of the filling shoe clamping plate can in particular be achieved without the other parameters being influenced and without an undesirable translational movement being initiated at the same time. Due to the preferred attachment of adjusting elements, such as spindles and / or scaling, the setting can preferably be carried out in a parameter-wise, precise, targeted and reproducible manner. In addition, it can be preferred in the context of the invention to use high-precision displacement measuring systems and / or motorized drive means in order to further optimize, automate and, in particular, simplify the setting of the inclination parameters.

In the context of the invention, it is particularly preferred to use closed components so that the proposed device can be inserted particularly well into a GMP-compliant overall solution.

It is therefore particularly preferred that the invention relates to a device for carrying a filling shoe plate and / or filling device, the device comprising an upper part, a lower part and an intermediate element, the upper part having a flat surface and a cylindrical underside and the intermediate element a cylindrical top and a cylindrical bottom having, the axes of the cylinders lying in a first spatial direction and in a second spatial direction to one another, the spatial directions enclosing a substantially right angle with one another, the shape of the underside of the upper part corresponding to a shape of the surface of the intermediate element and the upper part and the intermediate element are designed to be slidable in a first spatial direction to one another, and wherein the shape of the underside of the intermediate element corresponds to a shape of the surface of the lower part and the inter mediate element and the lower part are designed to be slidable to one another in a second spatial direction.

According to the invention, it is particularly preferred that the upper side of the lower part and the lower side of the intermediate element are designed in a manner similar to the components of a ball and socket joint, with the lower part representing the joint socket and the intermediate element representing the joint head and the intermediate element in addition is set up to move in a cavity of the lower part, which is preferably formed by the concave upper side of the lower part, in particular to rotate therein.

The components of the devices are advantageously secured at the same time in a form-fitting manner against undesired lifting off. The axes of the cylinder surfaces are preferably arranged essentially perpendicular to one another and in a spatial plane. In the context of the invention, it is preferred that the axes of the cylinder surfaces form virtual pivot axes of the device, the device in a preferred embodiment of the invention being able to assume the functionality of a joint and / or a rocking device. It is preferred in the context of the invention that the device can be designed variably through a suitable choice and arrangement of the cylinder axes and / or the cylinder radii and can be flexibly adapted to different needs.

In a preferred embodiment of the invention, the device comprises adjusting elements such as adjusting spindles and / or scales. As a result, the operability and reproducibility of the setting and / or adjustment of the component of the tableting machine to be adjusted can advantageously be improved. The scales can be arranged, for example, on the side surfaces of the components of the device, it preferably being height scales with a Information in the millimeter or micrometer range or an angle scale with information in the angle or sub-angle range.

The adjusting spindles can be, for example, tissue spindles or fine tissue spindles with which particularly fine adjustments can advantageously be achieved and / or adjusted. The adjustment of the spindles can be done manually, for example. The adjustment can, however, also take place with the aid of adjustment wheels with an integrated position indicator and / or by motor.

In a further embodiment of the invention, it is preferred that the device comprises disc springs. The plate springs can preferably be in the form of plate spring packages. The plate springs are preferably used to eliminate and / or reduce play between the components of the device and / or parts of the tabletting machine. In the context of the invention, it is particularly preferred that the plate springs are set up to permanently pre-tension the device. It is particularly preferred within the meaning of the invention that the play between the three components of the proposed device, namely the upper part, lower parts and intermediate element, is eliminated by means of two sets of cup springs given before.

It is also preferred that the device comprises tensioning elements. The provision of tensioning elements is advantageous in order to enable subsequent tensioning of the device and / or its components. It is preferred in the context of the invention that the device comprises at least one tensioning element, the tensioning elements in the context of the invention preferably also being referred to as tensioning devices. It is particularly preferred if the clamping devices are arranged essentially perpendicular to the device and / or the adjusting elements in order to avoid a subsequent adjustment of the position during clamping in a particularly effective manner.

The device can further comprise a height adjustment of the filling device underside relative to the matrix plate, which can be present, for example, in a support column of the proposed device. The height adjustment can in particular be designed as a mechanical cal height adjustment. In the context of the invention, it is preferred that the height adjustment can be used to set a distance, in particular a height distance, between the underside of the filling shoe plate and the surface of the die plate. The proposed device preferably enables components, ie components of a tablet machine, to be pivoted about defined “virtual axes”. In the context of the invention, this means in particular that the pivot axes themselves do not have to be represented by components, but rather the pivot axes can preferably be arranged in almost any position outside the device. In the context of the invention, it is also preferred if the pivot axes are “placed” in another component of the tableting machine without actually having “axes” - in the form of components - to be present there. In this way, the proposed device advantageously makes it possible to set a horizontal inclination of a clamping plate and preferably to define two clear-term, fixed and mutually perpendicular pivot axes at the height of the matrix.

In particular, a device is provided with which the inclination of the component of the tablet machine that is carried and / or picked up by the device can be changed successively about defined axes without the other parameters having to be influenced and without at the same time a displacement of the component of the tabletting machine is effected. In the context of the invention, a shift is preferably also referred to as a translational movement. In particular, the dreaded "tumbling movement" of the filling shoe clamping plate is avoided particularly effectively by the proposed invention, which is often problematic with conventional holders for filling shoe clamping plates, which usually work with a three-point support, adjustment and clamping, especially when an adjustment of the filling shoe plate is made at one point. This disadvantage can be attributed to the fact that in these conventional systems the respective pivot axis does not lie in the plane into which the filling shoe plate is to be pivoted. The present invention provides a remedy, in particular, in that the pivot axes advantageously each keep their point of intersection during adjustment, which takes place in particular independently of the two pivot angles and / or their position in space. This means that when one or the other parameter is adjusted, there is no undesirable "wobbling movement" of the filling shoe clamping plate or other machine parts. The invention is described below with the aid of an exemplary embodiment: The proposed device is based on components that are designed to slide on one another on cylindrical contact surfaces. At the same time, the components are preferably secured against lifting in a form-fitting manner. The axes of the cylinder surfaces can expediently be arranged perpendicular to one another in a plane. The axes of the cylinder surfaces preferably form “virtual” pivot axes of the device. By choosing and arranging the cylinder axes and radii, the swivel geometry of the device can be variably designed and adapted to various structural requirements within the tablet machine.

The proposed device can be fastened in a tablet machine with the lower part on a support column, wherein a manual or motorized height adjustment can be integrated within the support column. The proposed Vorrich device and the support column can be arranged on the carrier plate of the tablet machine, this unit preferably being used to hold the clamping plate on which a filling device can be attached. With the proposed device, the filling device attached to the clamping plate can be adjusted radially and axially to the surface of the die plate in a simple and reproducible manner.

The desired height distance between the underside of the filling shoe plate and the surface of the die plate is implemented in fine steps, manually or by motor, using the height adjustment integrated in the filling shoe support.

In the case of a tabletting machine for the production of tablets and other compacts, the press material is filled into the bores of the press dies with the aid of a filling device, which is preferably located above the die plate. The filling device is preferably plane-parallel to the die plate with a variable small distance above the die plate. This position of the filling device results preferably from the setting and / or adjustment of the filling shoe clamping plate on which the filling device is attached. The filling shoe clamping plate is attached to the proposed device. This device preferably has two pivot axes in the x and y directions, which can be essentially perpendicular to one another. It may also be preferred that with the upper Pivoting plane, the device about the x-axis is preferably aligned radially to the die plate. In addition, the proposed device can be aligned in the y-axis preferably tangential to the die with the lower pivot plane. In the context of the invention, it is also preferred that the adjustment about the pivot axes is carried out manually with adjusting spindles, a scale being able to be provided for reproducible adjustment. It can furthermore be preferred that handwheels with integrated scales are also used for the adjustment and / or that the adjustment can be carried out by a motor. Preferably, the position can be secured with a clamping device after the adjustment, wherein the clamping device can preferably also be referred to as a clamping device or clamping element in the context of the invention. The device can preferably be attached to a support column, with a sensitive manual height adjustment being able to be integrated into the support column. For the purposes of the invention, it is particularly preferred that the height adjustment is motorized.

It was completely surprising that the proposed device enables the swiveling of tablet machine components about defined “virtual” - that is not necessarily representational - axes. The present invention thus deliberately turns away from devices from the prior art in which the setting of the inclinations of a filling shoe clamping plate in a tablet machine has so far been accomplished by at least three vertically arranged adjusting elements. This can be, for example, spindles, screws and lock nuts. These adjustment elements can disadvantageously influence each other in their effect, that is, not every element is used exclusively to set a parameter assigned to it, but the adjustment elements can influence, for example, several or all degrees of freedom of the tablet animal machine component to be pivoted and / or adjusted.

Furthermore, the proposed device surprisingly avoids an undesirable translational movement of the tableting machine component. This can be caused by the fact that in conventional holding and adjusting devices, which are known from the prior art, the pivot axes lie outside the plane of the die table, which is disadvantageous can lead to the fact that the pivot axes can shift in space depending on the actuated adjusting element. As a result, in addition to the desired rotary movement of the tableting machine component, a predominantly horizontal, undesired translational movement is often generated, with the component being often additionally fixed and / or braced in the same direction as the setting, so that the setting result is undesirably through the subsequent fixation and / or tensioning is subsequently influenced, as a result of which an adjustment or setting of the filling shoe plate or the filling device once achieved can be lost again. This is advantageously achieved, in particular, in that the pivot axes each maintain their point of intersection during adjustment.
