Wenigstens einer der Spannteller ist mittels einer Verstelleinrichtung der Mischeinrichtung so verlagerbar, dass der Abstand zwischen den beiden Spanntellern veränderbar ist. Das heißt, dass der Abstand zwischen den beiden Spanntellern bei einer aufeinander zu gerichteten Verlagerungsbewegung, insbesondere zur Halterung eines Mischgutbehälters zwischen den Spanntellern, verkleinerbar ist und dass zum anderen der Abstand zwischen den beiden Spanntellern bei einer voneinander weggerichteten Verlagerungsbewegung vergrößerbar ist. Weiter ist eine Trennwand vorgesehen, die definierte Bauteile der Mischeinrichtung so voneinander trennt, dass die Spannteller der Mischeinrichtung in den Mischraum einragen und die Verstelleinrichtung auf der mischraumabgewandten Seite der Trennwand liegt. Erfindungsgemäß ist vorgesehen, dass die Mischeinrichtung die als Trennscheibe ausgebildete Trennwand aufweist und mit dieser um eine Drehachse drehbar im Inneren des Mischergehäuses gelagert istAccording to

Baueinheiten der Misch- bzw. Verstelleinrichtung erzielt, so dass etwaige aus dem Mischgutbehälter während des Mischens austretende Farbspritzer oder dergleichen zu keinem Verkleben oder zu keiner Verschmutzung der zum Beispiel beweglichen Bauteile der Mischeinrichtung führen können.

Die als Trennscheibe ausgebildete Trennwand kann dabei auf grundsätzlich unterschiedliche Art und Weise ausgebildet sein. Als Materialien können unterschiedlichste Materialien eingesetzt werden, insbesondere zum Beispiel ein Blechmaterial oder aber auch ein Kunststoffmaterial, um nur zwei Beispiele zu nennen. Die Trennwand selbst weist bevorzugt eine abgerundete, insbesondere eine runde oder ovale Außenkontur auf, wodurch sichergestellt ist, dass die zum Beispiel durch eine Trennscheibe gebildete Trennwand bei einer Betätigung der Mischeinrichtung einfach und ohne großen Luft- bzw. Strömungswiderstand in der Trennscheibenebene rotieren kann.The dividing wall designed as a partition can be designed in fundamentally different ways. As materials, a wide variety of materials can be used, in particular, for example, a sheet metal material or even a plastic material, to name just two examples.

Verlagerung wenigstens eines der Spannteller zu ermöglichen, ist gemäß einer besonders bevorzugten Ausgestaltung vorgesehen, dass der wenigstens eine verlagerbare Spannteller einen Spanntellerträger aufweist, an dem der Spannteller verdrehbar gehaltert ist und welcher Spanntellerträger aus dem Mischraum durch eine Schlitzausnehmung in der Trennwand hindurch zu der auf der mischraumabgewandten Seite der Trennwand liegenden Verstelleinrichtung geführt ist. Die trennwandseitige Schlitzausnehmung erstreckt sich dabei in Verlagerungsrichtung des zugeordneten Spanntellerträgers und gibt einen Verlagerungsweg des Spanntellerträgers innerhalb vorgegebener Einstellbereiche frei. In diesem Zusammenhang sei ausdrücklich erwähnt, dass auch bei der erfindungsgemäßen Ausgestaltung ein Spann- bzw. Drehtellerantrieb zum Antrieb wenigstens eines der Spannteller, vorzugsweise Drehteller vorhanden sein kann, wie er beispielsweise in der

Gemäß einer weiteren konkreten Ausgestaltung hierzu kann vorgesehen sein, dass das Abdeckelement relativ zum Spanntellerträger verlagerbar, insbesondere relativ zum Spanntellerträger verschwenkbar oder verdrehbar, an diesem gehaltert ist, wobei am Abdeckelement ein erstes Koppelelement der Zwangsführungseinrichtung angeordnet ist, das mit einem zweiten ortsfesten Koppelelement der Zwangsführungseinrichtung dergestalt mittelbar oder unmittelbar zusammenwirkt, dass das erste Koppelelement bei einer Verlagerung des Spanntellerträgers durch die mittelbar oder unmittelbare Zwangskopplung mit dem zweiten Koppelelement relativ zum Spanntellerträger in eine definierte Abdeckposition verlagerbar ist. Derartige Koppelelemente sind mit wenig Bauteilaufwand realisierbar und erlauben somit eine herstellungstechnisch einfache Ausbildung der Zwangsführungseinrichtung. Besonders bevorzugt ist dabei zum Beispiel das erste Koppelelement am Abdeckelement durch ein Zahnrad oder ein Zahnsegment gebildet, das mit einer das zweite Koppelelement bildenden Zahnstange zusammenwirkt. Ein derartiger Aufbau ist einfach herstellbar und weist eine hohe Funktionssicherheit bei der Betätigung auf.According to a further specific embodiment, it can be provided that the cover is displaceable relative to the clamping plate carrier, in particular relative to the clamping plate carrier pivotable or rotatable, is supported on this, wherein the cover a first coupling element of the forced guidance device is arranged, with a second stationary coupling element of the forced operation device cooperates indirectly or directly, that the first coupling element is displaceable relative to the clamping plate carrier in a defined covering position in a displacement of the tensioner carrier by the direct or indirect positive coupling with the second coupling element. Such coupling elements can be realized with little component effort and thus allow a manufacturing technology simple design of the positive guidance device. Particularly preferably, for example, the first coupling element is formed on the cover by a gear or a toothed segment, which cooperates with a second coupling element forming the rack. Such a structure is easy to manufacture and has a high reliability in the operation.
Gemäß einer weiteren bevorzugten Ausgestaltung ist das Abdeckelement durch eine längliche, insbesondere eine elliptische oder ovale Außenkontur aufweisende Abdeckscheibe gebildet, die an dem Spanntellerträger exzentrisch gelagert ist, und zwar dergestalt, dass die Abdeckscheibe in einer, bezogen auf die Schlitzausnehmung-Längsrichtung, oberen oder unteren Totpunktstellung des Spanntellerträgers mit ihrer Abdeckscheiben-Längsachse in etwa in Schlitzausnehmung-Längsrichtung ausgerichtet ist und dadurch die Abdeckscheibe mit ihrer, bezogen auf die exzentrische Lagerung, längeren Seite den sich von der jeweiligen Spannteller-Totpunktstellung weg zum anderen Totpunkt hin erstreckenden freien Schlitzbereich der Schlitzausnehmung abdeckt. Mit einer derartigen länglichen Ausgestaltung des Abdeckelementes wird der Bauteilaufwand insgesamt vorteilhaft reduziert und in Verbindung mit der Zwangsführungseinrichtung auf einfache Weise sichergestellt, dass stets der gewünschte, insbesondere der vollständige Bereich der freien Schlitzausnehmung abgedeckt ist.According to a further preferred embodiment, the cover is formed by an oblong, in particular an elliptical or oval outer contour having cover plate which is eccentrically mounted on the tensioner carrier, in such a way that the cover in a, relative to the slot recess longitudinal direction, upper or lower Dead center position of the clamping plate carrier is aligned with its cover disc longitudinal axis approximately in Schlitzausnehmung longitudinal direction and thereby covers the cover with their, based on the eccentric bearing, longer side extending from the respective clamping plate dead center position to the other dead point extending free slot area of the slot recess , With such an elongate configuration of the cover element, the component expense is advantageously reduced overall and, in conjunction with the positive guidance device, ensures in a simple manner that the desired, in particular the complete, region of the free slot recess is always covered.
In diesem Zusammenhang ist eine konkrete Ausgestaltung bevorzugt, bei der die längliche, insbesondere elliptische oder ovale, Außenkontur der Abdeckscheibe und/oder die Zwangsführungseinrichtung so ausgebildet ist bzw. sind, dass die Abdeckscheibe bei der Verlagerung des Spanntellerträgers von der einen Totpunktstellung zur anderen Totpunktstellung so verdrehbar ist, dass die Abdeckscheibe in beiden Totpunktstellungen mit ihrer Abdeckscheiben-Längsachse in etwa in Schlitzausnehmung-Längsrichtung ausgerichtet ist und dadurch die Abdeckscheibe mit jeweils ihrer längeren Seite den sich von der jeweiligen Spanntellerträger-Totpunktstellung weg, zum anderen Totpunkt hin erstreckenden freien Schlitzbereich der Schlitzausnehmung abdeckt. Auch in diesem Zusammenhang sei nochmals erwähnt, dass die Abdeckscheibe selbstverständlich so ausgebildet ist, dass zum Beispiel bei solchen Spanntellerträgerpositionen, bei denen, bezogen auf die Schlitzausnehmung-Längsrichtung, ein freier Schlitzbereich sowohl oberhalb als auch unterhalb des Spanntellerträgers ausgebildet ist, beide Bereiche mittels der Abdeckscheibe abgedeckt sein sollen.In this context, a specific embodiment is preferred, in which the elongated, in particular elliptical or oval, outer contour of the cover and / or the positive guide means is or are designed so that the cover so in the displacement of the tensioner carrier from the one dead center to the other dead center is rotatable that the cover is aligned in two dead center positions with its cover disc longitudinal axis approximately in Schlitzausnehmung longitudinal direction and thereby the cover, each with its longer side away from the respective pan carrier Totpunktstellung away, to the other dead point extending free slot area of the slot recess covers. It should also be mentioned again in this context that the cover disk is, of course, designed so that, for example, at such a clamping plate carrier positions, in which, based on the slot recess longitudinal direction, a free slot area both above is formed as well as below the tensioner carrier, both areas should be covered by means of the cover.
Gemäß einer weiteren konkreten Ausgestaltung ist vorgesehen, dass die Zahnstange auf der mischraumabgewandten Seite der Trennwand angeordnet ist und im Wesentlichen parallel und beabstandet dazu wenigstens eine Führungsstange angeordnet ist, wobei sich die wenigstens eine Zahnstange und die Führungsstange zwischen zwei jeweils verlagerbar ausgebildeten Spanntellerträgern erstrecken und die abdeckelementseitigen Zahnräder oder Zahnsegmente im Bereich zwischen den beiden Stangen angeordnet sind. Damit ergibt sich insgesamt ein kompakter Aufbau. Bevorzugt ist weiter vorgesehen, dass an den Stangen, vorzugsweise in einem mittleren Bereich der Längserstreckungsrichtung der Stangen, ein Aufnahmelager für eine Mischerwelle angeordnet und abgestützt ist, mittels welcher Mischerwelle die gesamte Mischeinrichtung, vorzugsweise motorisch angetrieben, im oder gegen den Uhrzeigersinn drehbar ist. Insgesamt lässt sich mit einem derartigen konkreten Aufbau eine mechanisch stabile Anordnung ausbilden, die besonders gut für den rauen Mischbetrieb geeignet ist.According to a further specific embodiment, it is provided that the toothed rack is arranged on the side facing away from the mixing chamber and substantially parallel and spaced therefrom at least one guide rod is arranged, wherein the at least one rack and the guide rod between two each movable displaceable clamping plate carriers extend and the cover element side gears or toothed segments are arranged in the region between the two rods. This results in a total of a compact design. Preferably, it is further provided that a receiving bearing for a mixer shaft is arranged and supported on the rods, preferably in a central region of the longitudinal direction of the rods, by means of which mixer shaft, the entire mixing device, preferably motor driven, is rotatable clockwise or counterclockwise. Overall, with such a concrete structure can form a mechanically stable arrangement, which is particularly well suited for rough mixing operation.
Die Abdeckeinrichtung selbst, die bevorzugt durch eine Abdeckscheibe gebildet ist, liegt gemäß einer besonders bevorzugten konkreten Ausgestaltung in einer flächigen Anlageverbindung an der Trennwand an und ist relativ zu dieser verlagerbar, insbesondere verdrehbar oder verschwenkbar, wie zuvor geschildert. Durch die bevorzugt flächige Anlageverbindung ist sichergestellt, dass keinerlei Mischgut über die Schlitzausnehmung in den mischraumabgewandten Bereich hinter die Trennwand gelangen kann. Grundsätzlich wäre jedoch auch die Ausbildung einer Abdeckeinrichtung möglich, die mit einem definierten Spaltabstand zur Trennwand ausgebildet ist, um Verklebungseffekte der Bauteile zu vermeiden. Auch mit einer solchen Ausgestaltung kann gegebenenfalls zuverlässig eine Verschmutzung der besonders gefährdeten Bereiche der Mischeinrichtung auf der mischraumabgewandten Seite der Trennwand zuverlässig vermieden werden.The covering device itself, which is preferably formed by a cover, according to a particularly preferred specific embodiment in a planar abutment connection to the partition wall and is displaceable relative to this, in particular rotatable or pivotable, as described above. The preferred flat contact connection ensures that no mix can reach beyond the partition wall via the slot recess in the region facing away from the mixing space. In principle, however, the formation of a cover device would be possible, which is formed with a defined gap distance to the partition to avoid adhesion effects of the components. Even with such a configuration can possibly reliably pollution of the Particularly vulnerable areas of the mixing device on the mixing chamber side facing away from the partition wall can be reliably avoided.
Die Verstelleinrichtung selbst weist bevorzugt einen Spindeltrieb mit einer pro verstellbarem Spanntellerträger vorgesehenen Gewindespindel auf, welche Gewindespindel auf der mischraumabgewandten Seite der Trennwand ortsfest und verdrehbar angeordnet ist und auf der mischraumabgewandten Seite der Trennwand mit dem Spanntellerträger bzw. einem dort angeordneten und eine Spindelmutter aufweisenden Spanntellerträger-Lagerelement zur Verstellung des zugeordneten Spanntellerträgers zusammenwirkt. Hierbei kann des Weiteren bevorzugt vorgesehen sein, dass das Spanntellerträger-Lagerelement entlang wenigstens einer Führungsstange verschiebbar gelagert ist, wobei die Führung entlang mehrerer Führungsstangen bevorzugt ist. Mit einem derartigen Spindeltrieb ist eine funktionssichere Verstellung der Spanntellerträger und damit der Spannteller gewährleistet, wobei über den Spindeltrieb zudem auch aufgrund der Selbsthemmung zwischen Gewindespindel und Spindelmutter eine einfach zu bewerkstelligende Festlegung und Halterung der Spanntellerträger in einer einmal eingenommenen Position gewährleistet ist.The adjusting device itself preferably has a spindle drive with a per ver adjustable clamping plate provided threaded spindle, which threaded spindle on the mixing chamber side facing away from the partition is fixed and rotatable and arranged on the mixing chamber side facing away from the partition with the tensioner carrier or a there arranged and a spindle nut having Spanntellerträger- Bearing element cooperates to adjust the associated tensioner carrier. In this case, it can further preferably be provided that the clamping plate carrier bearing element is displaceably mounted along at least one guide rod, wherein the guide along several guide rods is preferred. With such a spindle drive a functionally reliable adjustment of the clamping plate carrier and thus the clamping plate is guaranteed, which is also ensured due to the spindle drive due to the self-locking between the threaded spindle and spindle nut easy to bewerkstelligende fixing and mounting the pan carrier in a once occupied position.
Bevorzugt ist vorgesehen, dass die Trennwand durch eine einfache, leichte Platte ausgebildet ist, die keine tragende Funktion übernimmt. Gemäß einer alternativen Ausgestaltung der vorliegenden Erfindungsidee kann jedoch gegebenenfalls auch vorgesehen sein, dass ein definierter Teil der auf der mischraumabgewandten Seite der Trennwand liegenden Bauteile oder Baueinheiten, insbesondere die Verstelleinrichtung und/oder die zur Mischerbetätigung und/oder zur Betätigung der Verstelleinrichtung erforderlichen Bauteile oder Baueinheiten, wenigstens zum Teil mittelbar und/oder unmittelbar an der Trennwand auf der mischraumabgewandten Seite der Trennwand festgelegt sind. Die Trennwand weist somit in diesem Fall neben ihrer Abschirmfunktion gleichzeitig eine weitere Funktion als Haltemittel für ohnehin im Mischergehäuse vorhandene Bauteile auf. Damit würde sich eine weitere hohe Funktionsintegration erzielen lassen.It is preferably provided that the partition wall is formed by a simple, lightweight plate that does not assume a supporting function. According to an alternative embodiment of the present inventive concept, however, it may also be provided that a defined part of the components or assemblies lying on the side of the partition facing away from the mixing chamber, in particular the adjusting device and / or the components or assemblies required for the mixer operation and / or for the actuation of the adjusting device , at least partially indirectly and / or directly fixed to the partition on the mixing chamber side facing away from the partition. The partition thus has in this case next their shielding function at the same time a further function as a holding means for already existing in the mixer housing components. This would allow a further high functional integration to be achieved.
Gemäß einer besonders bevorzugten konkreten Ausgestaltung wird vorgeschlagen, dass bei zwei verstellbaren Spanntellerträgern zwei separate und voneinander beabstandete Schlitzausnehmungen vorgesehen sind, in denen jeweils ein Spanntellerträger verschiebbar geführt ist. In diesem Fall ist dann die Trennwand mit bezogen auf die Schlitzausnehmungen, gegenüberliegenden, die Schlitzausnehmungen zwischen sich aufweisenden Trennwandbereichen, an jeweils einem Lagerbock angeordnet, an denen das mit den abdeckscheibenseitigen Formschlusselementen, zum Beispiel Zahnrädern oder Zahnsegmenten, zusammenwirkende Formschlussgegenelemente, zum Beispiel eine Zahnstange, jeweils endseitig gelagert ist und/oder an denen die wenigstens eine Führungsstange, entlang der die Spanntellerträgerteile verschiebbar geführt sind, endseitig gelagert ist, wobei bevorzugt vorgesehen ist, dass sowohl die Führungsstangen als auch das Formschlussgegenelement an dem eine Mischerwelle einer Antriebseinheit aufnehmenden Aufnahmelager gehaltert ist. Es versteht sich von selbst, dass hierbei dann auch die Mischereinheit im Mischergehäuse verdrehbar gelagert und gehaltert ist.According to a particularly preferred specific embodiment, it is proposed that two separate and spaced slot recesses are provided in two adjustable clamping plate carriers, in each of which a clamping plate carrier is slidably guided. In this case, then the partition wall with respect to the slot recesses, opposite, the slot recesses between them having partition wall regions, each arranged on a bearing block, which interacts with the cover plate-side form-fitting elements, such as gears or toothed segments positive locking counter-elements, for example a rack each end is mounted and / or on which the at least one guide rod, along which the clamping plate carrier parts are displaceably guided, is mounted end, wherein it is preferably provided that both the guide rods and the positive locking counter-element is mounted on the mixer shaft of a drive unit receiving receiving bearing. It goes without saying that in this case also the mixer unit is rotatably mounted and supported in the mixer housing.
Mit einem derartigen konkreten Aufbau lassen sich hervorragende Mischergebnisse erzielen, ohne dass es zu einer unerwünschten Verschmutzung der zur Betätigung der Mischeinrichtung erforderlichen und im Mischergehäuse angeordneten Bauteile kommt.With such a concrete structure, excellent mixing results can be achieved without undesirable contamination of the components required for actuating the mixing device and arranged in the mixer housing.
