Description

Gegenstand der Erfindung ist eine Mischvorrichtung mit einer gegenüber einem Grundgestell schwenkbar gelagerten Einrichtung zum Erzeugen eines Mischgutstroms innerhalb eines, ein Festkörpermischgut enthaltenden, eine oberseitige Öffnung aufweisenden Mischbehälters, welche Mischgutstrom-Erzeugungseinrichtung über ein Verschlusselement zum Verschließen der oberseitigen Öffnung des Mischbehälters sowie über ein oder mehrere Anschlussmittel zum Anschließen eines das Mischgut enthaltenden Mischbehälters verfügt. Die Erfindung betrifft ferner eine Mischvorrichtungsanordnung mit einer solchen Mischvorrichtung und einem Mischbehälter.The invention relates to a mixing device with a relative to a base frame pivotally mounted device for generating a Mischgutstroms within a, a solid state mixture containing a top-side opening having mixing container, which Mischgutstrom-generating device via a closure element for closing the upper-side opening of the mixing container and one or more Connection means for connecting a mixing container containing the mix has.

Bei derartigen Mischvorrichtungen handelt es sich um industrielle Mischer, die zum Mischen von Schüttgut, etwa von pulverförmigem Schüttgut, zum Erstellen von Kunststoffgranulatgemischen eingesetzt werden. Ein solcher Mischer ist beispielsweise aus DE 197 08 075 C1 bekannt. Diese vorbekannte Mischvorrichtung verfügt über eine Mischgutstrom-Erzeugungseinrichtung, mit der das innerhalb des Mischbehälters befindliche Mischgut unter Ausbildung eines Mischgutstromes in Bewegung versetzt wird. Der Mischbehälter dieser Mischvorrichtung besteht aus zwei Teilen, wobei der eine Mischbehälterteil das zu mischende Mischgut enthält und der andere Mischbehälterteil der Mischgutstrom-Erzeugungseinrichtung zugeordnet ist. Beide Mischbehälterteile sind zumindest in ihrem aneinander angrenzenden Bereich zylinderförmig konzipiert. Das der Mischgutstrom-Erzeugungseinrichtung zugeordnete Mischbehälterteil verfügt über einen nach außen abragenden Anschlussflansch, an die oberseitige Öffnung des anderen Mischbehälterteils durch pneumatische Drehverschlüsse anschließbar ist. Das andere Mischbehälterteil trägt unterseitig Rollen und kann, wenn nicht an das der Mischgutstrom-Erzeugungseinrichtung zugeordnete Mischbehälterteil angeschlossen, über diese bewegt werden. Das der Mischgutstrom-Erzeugungseinrichtung zugeordnete Mischbehälterteil ist zum Erzeugen eines Mischgutstromes durch ein auf die rückwärtige Außenseite dieses Mischbehälterteils wirkendes Reibrad rotatorisch angetrieben. Eine Durchmischung des in dem aus den beiden Mischbehälterteilen zusammengesetzten Mischbehälters erfolgt somit durch die Drehmitnahme des Mischgutes an der Mischbehälterwand. Zusätzlich können innerhalb des der Mischgutstrom-Erzeugungseinrichtung zugehörigen Mischbehälterteils motorisch angetriebene Dispergierwerkzeuge angeordnet sein. Die Mischgutstrom-Erzeugungseinrichtung dieser vorbekannten Mischvorrichtung ist um eine horizontal liegende Schwenkachse gegenüber einem Grundgestell kippbar, um den Mischbehälter für die Zwecke der Durchmischung in eine über Kopf geneigte Schräglage zu bringen. In dieser Mischlage ist eine größere Innenfläche des aus den beiden Behälterteilen zusammengesetzten Mischbehälters auf das darin befindliche Mischgut zum Erzeugen eines Mischgutstromes in Kontakt gebracht. Bei dieser Mischvorrichtung ist es erforderlich, die Drehbewegung der Mischgutstrom-Erzeugungseinrichtung und damit von dem dieser Einrichtung zugehörigen Mischbehälterteils auf den anderen Mischbehälterteil zu übertragen.Such mixing devices are industrial mixers used for mixing bulk material, such as powdered bulk material, to create plastic granulate mixtures. Such a mixer is for example off DE 197 08 075 C1 known. This previously known mixing device has a Mischgutstrom-generating device with which the mixing material located within the mixing container is set to form a Mischgutstromes in motion. The mixing container of this mixing device consists of two parts, one of the mixing container part containing the mixing material to be mixed and the other mixing container part of the Mischgutstrom-generating device is assigned. Both mixing container parts are designed to be cylindrical, at least in their adjoining region. The Mischbehälterteil assigned to the Mischgutstromgenerator has a projecting outwardly flange, to the top opening of the other Mischbehälterteils is connected by pneumatic screw caps. The other mixing container part carries rollers on the underside and, if not connected to the Mischbehälgengenerator associated Mischbehälterteil be moved over this. The Mischbehälterteil associated with the Mischgutstrom-generating device is rotatably driven to generate a Mischgutstromes by acting on the rear outside of this Mischbehälterteils friction wheel. A mixing of the mixed container composed of the two mixing container parts is thus effected by the rotational drive of the mixed material at the mixing vessel wall. In addition, motor-driven dispersing tools can be arranged within the mixing container part associated with the mixing material flow generating device. The Mischgutstrom-generating device of this prior art mixing device is tiltable about a horizontal pivot axis relative to a base frame to bring the mixing container for the purpose of mixing in an inclined over inclined head. In this mixed layer, a larger inner surface of the mixing container composed of the two container parts is brought into contact with the material to be mixed therein for producing a mixed material flow. In this mixing device, it is necessary to transfer the rotary motion of the mixed material flow generating device and thus of the mixing container part associated with this device to the other mixing container part.

In der Praxis wird eine solche Mischvorrichtung zum Mischen unterschiedlicher Mischgüter eingesetzt, die nacheinander gemischt werden sollen. Diese werden in dem mit Rollen versehenem Mischbehälterteil an die Mischvorrichtung herangefahren, an den mischvorrichtungsseitigen Mischbehälterteil angeschlossen, in die Mischstellung verschwenkt und für eine vorgesehene Zeitdauer in Drehbewegung versetzt. Nach Abschluss des Mischvorganges wird der Mischbehälter in seiner Ausgangslage zurückgeschwenkt und der mit Rollen versehene Mischbehälterteil von dem anderen Mischbehälterteil gelöst und weggefahren. Für den Fall, dass in einem nächsten Mischprozess mit dieser Mischvorrichtung ein anderes Mischgut gemischt werden soll, ist es erforderlich, sämtliche mit dem zuvor gemischten Mischgut in Kontakt befindlichen Teile der Mischgutstrom-Erzeugungseinrichtung zu säubern. Dieses betrifft den der Mischgutstrom-Erzeugungseinrichtung zugehörigen Behälterteil, die Dispergierwerkzeuge sowie die Antriebswelle, auf der die Dispergierwerkzeuge sitzen. Neben einem Reinigen dieser Teile der Mischvorrichtung ist nach Entnahme des gemischten Mischgutes aus dem mit Rollen versehenen Mischbehälterteil auch dieser zu reinigen, bevor in diesen ein anderes zu mischendes Mischgut eingefüllt werden kann. Die bei einem Betrieb einer solchen Mischvorrichtung notwendige Reinigungszeit beträgt ein Vielfaches der eigentlichen Mischzeit. Um eine sorgfältige Reinigung durchzuführen, müssen mitunter zwei Stunden veranschlagt werden. Das Mischen selbst dauert dagegen oftmals nur wenige Minuten.In practice, such a mixing device is used for mixing different blends which are to be mixed successively. These are moved up in the mixing container part provided with rollers to the mixing device, connected to the mixing device side mixing container part, pivoted into the mixing position and set in rotation for a given period of time. After completion of the mixing process, the mixing container is pivoted back to its original position and the mixing container part provided with rollers is detached from the other mixing container part and moved away. In the event that another mix is to be mixed in a next mixing process with this mixing device, it is necessary to clean all parts of the Mischgutstrom-generating device in contact with the previously mixed mix in contact. This relates to the container part associated with the mixed material flow generating device, the dispersing tools and the drive shaft on which the dispersing tools are seated. In addition to cleaning these parts of the mixing device after removal of the mixed mix from the provided with rolls mixing container part and this clean before it can be filled in this another mixed to be mixed. The necessary during an operation of such a mixing device cleaning time is a multiple of the actual mixing time. In order to carry out a thorough cleaning, it may sometimes take two hours to estimate. The mixing itself often only takes a few minutes.

Neben Mischvorrichtungen, wie diese aus der DE 197 08 075 C1 bekannt geworden sind, sind auch solche bekannt, bei denen der Mischgutstrom nicht durch Rotation des Mischbehälters um seine Längsachse, sondern durch innerhalb des ansonsten ruhenden Mischbehälters rotatorisch angetriebene Mischwerkzeuge erzeugt wird. Auch derartige Mischvorrichtungen verfügen über zwei, nach ihrer Verbindung den Mischbehälter bildende Mischbehälterteile. Der zum Reinigen notwendige Aufwand entspricht demjenigen der zuvor beschriebenen Mischvorrichtung.In addition to mixing devices, like these from the DE 197 08 075 C1 have become known, even those are known in which the Mischgutstrom is not generated by rotation of the mixing container about its longitudinal axis, but by within the otherwise stationary mixing container rotationally driven mixing tools. Also, such mixing devices have two, after their connection forming the mixing vessel Mischbehälterteile. The effort required for cleaning corresponds to that of the mixing device described above.

Dokument EP-A-0 648 526 offenbart eine Mischvorrichtung gemäß dem Oberbegriff des Anspruchs 1. Ausgehend von diesem diskutierten Stand der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine eingangs genannte Mischvorrichtung dergestalt weiterzubilden, dass bei dieser insbesondere die Reinigungsarbeiten weniger zeitaufwendig sind.document EP-A-0 648 526 discloses a mixing device according to the preamble of claim 1. Based on this discussed prior art, the invention is therefore the object of developing an aforementioned mixing device in such a way that in this particular cleaning work is less time consuming.

Gelöst wird diese Aufgabe durch eine eingangs genannte, gattungsgemäße Mischvorrichtung mit den Merkmalen des Anspruchs 1, bei der das oder die Anschlussmittel zum Anschließen des Mischbehälters an die Mischgutstrom-Erzeugungseinrichtung funktional von dem Verschlusselement getrennt angeordnet sind und zu diesem Zweck die Mischgutstrom-Erzeugungseinrichtung über eine zumindest ein Kupplungsglied aufweisende Anschlusseinrichtung verfügt, wobei das zumindest eine Kupplungsglied mit Abstand zu dem oberseitigen Öffnungsbereich des Mischbehälters an diesen anschließbar ist.This object is achieved by an aforementioned generic mixing device with the features of claim 1, wherein the one or more connection means for connecting the mixing container to the Mischgutstrom-generating device are arranged functionally separate from the closure element and for this purpose the Mischgutstrom-generating device via a at least one coupling member having connecting device, wherein the at least one coupling member with distance to the upper-side opening portion of the mixing container can be connected thereto.

Bei dieser Mischvorrichtung ist eine räumliche Trennung zwischen dem der Mischgutstrom-Erzeugungseinrichtung zugeordneten Verschlusselement zum Verschließen der oberseitigen Öffnung eines Mischbehälters und dem oder den Anschlussmitteln zum Anschließen des Mischbehälters an die Mischgutstrom-Erzeugungseinrichtung vorgesehen. Zu diesem Zweck verfügt die Anschlusseinrichtung über ein oder mehrere Kupplungsglieder, die mit Abstand zur oberseitigen Öffnung des Mischbehälters an diesen anschließbar sind. Eine Beabstandung der Kupplungsglieder von der oberseitigen Öffnung des Mischbehälters kann in radialer Richtung und/oder in Richtung der Längsachse des Mischbehälters vorgesehen sein. Bei dieser Mischvorrichtung braucht typischerweise über das Verschlusselement kein Drehmoment auf einen daran anzuschließenden Mischbehälter übertragen werden. Dieses erfolgt mit der Anschlusseinrichtung, für den Fall, dass ein Drehmoment von dem Verschlusselement der Mischgutstrom-Erzeugungseinrichtung auf den Mischbehälter übertragen werden soll. Das Verschlusselement als solches kann daher sehr einfach ausgebildet sein. Letztendlich ist es ausreichend, als Verschlusselement eine Platte oder einen Deckel vorzusehen, der unter Zwischenschaltung eines Dichtelementes in die oberseitigen Öffnung des Mischbehälters eingreift. Eine Abdichtung kann im Behälterstutzen erfolgen, so etwa durch Vorsehen einer aufblasbaren, in radialer Richtung gegen die Innenwandung der Öffnung wirkenden aufblasbaren Dichtung. Bei einem derart konzipierten Verschlusselement werden Todräume im Behälter vermieden. Grundsätzlich ebenfalls möglich ist, das Verschlusselement dergestalt zu konzipieren, damit dieses auf der Oberseite eines die Öffnung einfassenden Flansches anliegt, und zwar unter einer durch die Anschlusseinrichtung bereitgestellten Vorspannung. Zu reinigen ist bei einer solchen Mischvorrichtung somit nur noch das hinsichtlich seiner Geometrie typischerweise sehr einfach ausgebildete Verschlusselement und das oder die gegebenenfalls dieses durchgreifenden Mischwerkzeuge. Insbesondere brauchen bei dieser Mischvorrichtung nicht die ansonsten mit dem Mischgut in Kontakt gebrachten Anschlusseinrichtungen gereinigt werden, da diese sich außerhalb und mit Abstand von der oberen Öffnung des Mischbehälters befinden.In this mixing device, a spatial separation between the mixing material flow generating device associated closure element for closing the top opening of a mixing container and the one or more connection means for connecting the mixing container to the Mischgutstrom-generating device is provided. For this purpose, the connection device has one or more coupling members, which are connectable to the top opening of the mixing container at this distance. A spacing of the coupling members from the upper-side opening of the mixing container may be provided in the radial direction and / or in the direction of the longitudinal axis of the mixing container. In this mixing device, typically no torque is needed to be connected thereto via the closure element Mixing container to be transferred. This is done with the connection device, in the event that a torque is to be transmitted from the closure element of the Mischgutstrom-generating device to the mixing container. The closure element as such can therefore be designed very simply. Finally, it is sufficient to provide as a closure element a plate or a lid, which engages with the interposition of a sealing element in the upper-side opening of the mixing container. A seal can be made in the container neck, such as by providing an inflatable, acting in the radial direction against the inner wall of the opening inflatable seal. In a closure element designed in this way, dead spaces in the container are avoided. In principle, it is also possible to design the closure element in such a way that it rests on the upper side of a flange enclosing the opening, specifically under a prestress provided by the connection device. In such a mixing device, therefore, it is only necessary to clean the closure element, which is typically very simple in terms of its geometry, and / or the mixing tool (s), if necessary, which penetrates it. In particular, need not be cleaned in this mixing device otherwise brought into contact with the mix connection means, as they are located outside and at a distance from the upper opening of the mixing container.

Die vorgeschriebene Konzeption des Mischbehälters hat zudem den Vorteil, dass als Mischbehälter grundsätzlich jedweder Behälter eingesetzt werden kann, dessen Öffnung durch das Verschlusselement verschließbar ist und der durch die Anschlusseinrichtung ergriffen werden kann. Somit kann mit dieser Mischvorrichtung auch ein als Schüttgutcontainer konzipierter Behälter als Mischbehälter eingesetzt werden, ohne dass ein Umfüllen des zu mischenden Mischgutes in einen Mischbehälter notwendigen wäre. Dementsprechend entfällt bei einer derartigen Mischvorrichtung auch das Reinigen eines zu dem der Mischvorrichtung zugeordneten Mischbehälterteil komplementären Mischbehälterteils.The prescribed design of the mixing container also has the advantage that as a mixing container basically any container can be used, the opening of which can be closed by the closure element and which can be gripped by the connection device. Thus, with this mixing device, a container designed as a bulk container can also be used as a mixing container without it being necessary to transfer the mixture to be mixed into a mixing container. Accordingly, in such a mixing device, the cleaning of a mixing container part which is complementary to the mixing container part associated with the mixing device also does not occur.

Zum Anschließen eines als Mischbehälter dienenden Behälters an die Mischgutstrom-Erzeugungseinrichtung verfügt die Mischvorrichtung vorzugsweise über zwei oder mehr Anschlussarme mit jeweils einem Kupplungsglied. Das Kupplungsglied jedes Anschlussarmes ist durch einen eigenen oder durch einen gemeinsamen Aktor in seiner durch den Aktor definierten Bewegungsrichtung bewegbar. Das oder die Kupplungsglieder sind vorzugsweise ausgeführt, damit diese einen Absatz des Mischbehälters formschlüssig hintergreifen und damit dieser anschließend durch Betätigen des oder Aktoren an das Verschlusselement der Mischgutstrom-Erzeugungseinrichtung herangeführt werden. Als Aktoren können beispielsweise Spindelhubgetriebe vorgesehen sein, deren Gewindespindel jeweils in einem Anschlussarm angeordnet sind. Anstelle eines Spindelhubgetriebes können neben zahlreichen anderen möglichen Ausgestaltungen zum Anschließen des Mischbehälters an die Mischgutstrom-Erzeugungseinrichtung auch motorisch bewegte Zahnstangen oder preumatisch oder hydraulisch betätigte Zylinder dienen, an denen jeweils ein Kupplungsglied angeschlossen ist. Durch translatorische Bewegen der Zahnstangen werden die das oder die Kupplungsglieder entsprechend bewegt.For connecting a container serving as a mixing container to the Mischgutstrom-generating means, the mixing device preferably has two or more connecting arms, each having a coupling member. The coupling member of each connecting arm is movable by its own or by a common actuator in its direction of movement defined by the actuator. The one or more coupling members are preferably designed so that they engage behind a paragraph of the mixing container form fit and thus this are then brought by pressing the actuator or actuators to the closure element of the Mischgutstrom-generating device. As actuators, for example Spindelhubgetriebe can be provided, the threaded spindle are each arranged in a connecting arm. Instead of a Spindelhubgetriebes also motor-driven racks or preumatisch or hydraulically actuated cylinder can serve in addition to numerous other possible embodiments for connecting the mixing container to the Mischgutstrom-generating device, to each of which a coupling member is connected. By translational movement of the racks the or the coupling members are moved accordingly.

Die Mischgutstrom-Erzeugungseinrichtung kann konzipiert sein, dass das in dem an diese angeschlossenen Mischbehälter befindliche Mischgut durch die Mantelreibung des Mischbehälters erzeugt wird und zu diesem Zweck der Mischbehälter in eine Rotationsbewegung um seine Längsachse versetzt wird. Gleichfalls ist es möglich, eine Mischbewegung im Wege eines Mischgutstromes durch ein oder mehrere, innerhalb des Mischbehälters angeordnete Mischwerkzeuge zu erzeugen. Derartige Mischwerkzeuge sitzen typischerweise auf einer motorisch angetriebenen Welle, die ihrerseits das Verschlusselement entsprechend abgedichtet durchgreift. Bei einer solchen Konzeption sind das oder die Mischwerkzeuge ausgelegt, um durch die oberseitige Öffnung eines das zu mischende Mischgut enthaltenden Behälters - dem Mischbehälter - eingeführt werden zu können. Verfügt ein solcher Mischbehälter als oberseitige Öffnung beispielsweise nur über ein Mannloch, sind das oder die Mischwerkzeuge konzipiert, um durch dieses Mannloch im Zuge des Anschließens dieses Behälters an das Verschlusselement bzw. die Mischgutstrom-Erzeugungseinrichtung hindurchgeführt werden zu können. Wird zum Erzeugen des Mischgutstromes ein vom Durchmesser her größeres Mischwerkzeug als der Durchmesser eines solchen Mannloches benötigt, ist dieses beispielsweise entsprechend klappbar ausgebildet. Bei Vorsehen eines Mischwerkzeugs als Mischwerkzeug können dessen Flügel gegenüber der Mischwerkzeugnabe abklappbar sein. Da bei einer Konzeption einer solchen Mischvorrichtung, insbesondere wenn der Mischgutstrom durch in dem Mischbehälter eingreifende Werkzeuge erzeugt werden soll, der Mischvorgang selbst in einer Überkopfanordnung durchgeführt wird und zu diesem Zweck der Mischbehälter zusammen mit der Mischgutstrom-Erzeugungseinrichtung um eine horizontal liegende Schwenkachse gegenüber einem Grundgestell gekippt wird, braucht die das oder die Mischwerkzeuge tragende Welle nur eine kurze Erstreckung aufzuweisen. Durch das Schwenken der aus Mischbehälter und Mischgutstrom-Erzeugungseinrichtung gebildeten Einheit in ihre Mischstellung befinden sich die Mischwerkzeuge dann in einer unteren, von dem Mischgut bedeckten Position.The mixed material flow generating device can be designed so that the mixing material contained in the mixing container connected thereto is generated by the jacket friction of the mixing container and for this purpose the mixing container is set in a rotational movement about its longitudinal axis. Likewise, it is possible to produce a mixing movement in the way of a Mischgutstromes by one or more, arranged within the mixing vessel mixing tools. Such mixing tools typically sit on a motor-driven shaft, which in turn passes through the closure element in a sealed manner. In such a concept, the mixing tool or tools are designed to be introduced through the top-side opening of a container containing the mixture to be mixed - the mixing container. For example, if such a mixing container has only one manhole as the top opening, the mixing tool or tools are designed to be passed through this manhole in the course of connecting this container to the closure element or the mixed material flow generating device. If a mixing tool of larger diameter than the diameter of such a manhole is required to produce the stream of mixed material, this is designed, for example, correspondingly foldable. With provision of a Mixing tool as a mixing tool whose wings relative to the Mischwerkzeugnabe be folded down. Since, in a conception of such a mixing device, in particular when the mixing material flow is to be generated by engaging in the mixing container tools, the mixing process itself is performed in an overhead arrangement and for this purpose the mixing vessel together with the Mischgutstrom-generating means about a horizontal pivot axis relative to a base frame tilted, the shaft carrying the or the mixing tools need only have a short extension. By pivoting the unit formed from mixing container and Mischgutstrom-generating device into its mixing position, the mixing tools are then in a lower, covered by the mix position.

Nachfolgend ist die Erfindung anhand eines Ausführungsbeispiels unter Bezugnahme auf die beigefügten Figuren beschrieben. Es zeigen:

Eine Mischvorrichtung 1 verfügt über ein Grundgestell 2, an dem mittels eines Schwenkrahmens 3 eine insgesamt mit dem Bezugszeichen 4 gekennzeichnete Mischgutstrom-Erzeugungseinrichtung schwenkbar angelegt ist. Die Mischgutstrom-Erzeugungseinrichtung 4 ist ihrerseits innerhalb des Schwenkrahmens 3 schwenkbar gelagert. Die Schwenkachse der Mischgutstrom-Erzeugungseinrichtung 4 innerhalb des Schwenkrahmens 3 ist mit dem Bezugszeichen 5 gekennzeichnet. Die Schwenkachse des Schwenkrahmens 3 gegenüber dem Grundgestell 2 ist mit dem Bezugszeichen 6 gekennzeichnet. Beide Schwenkachsen 5, 6 sind rechtwinklig zueinander in einer horizontal verlaufend Ebene angeordnet. Mithin ist die Mischgutstrom-Erzeugungseinrichtung 4 kardanisch gegenüber dem Grundgestell 2 gelagert. Das Grundgestell 2 verfügt über zwei Ständer 7, 8, die jeweils als U-förmige Profile ausgeführt sind. In dem Ständer 7 ist ein Getriebemotor 9 angeordnet, durch den der Schwenkrahmen 3 um seine Schwenkachse 6 verschwenkt werden kann. Ein weiterer Getriebemotor 10 dient zum Verschwenken der Mischgutstrom-Erzeugungseinrichtung 4 um die Schwenkachse 5 innerhalb des Schwenkrahmens 3. Durch die Motoren 9, 10 kann die Mischgutstrom-Erzeugungseinrichtung 4 aufgrund ihrer kardanischen Lagerung innerhalb des jeweiligen Bewegungsspielraumes in jede beliebige Raumlage verschwenkt werden.A mixing device 1 has a base frame 2, on which by means of a pivoting frame 3, a mixed material flow generating device, indicated generally by the reference numeral 4, is pivotally mounted. The Mischgutstrom-generating device 4 is in turn pivotally mounted within the swing frame 3. The pivot axis of the Mischgutstrom-generating device 4 within the swing frame 3 is marked with the reference numeral 5. The pivot axis of the swing frame 3 relative to the base frame 2 is marked with the reference numeral 6. Both pivot axes 5, 6 are arranged at right angles to each other in a horizontally extending plane. Consequently, the Mischgutstrom-generating device 4 is gimballed relative to the base frame 2. The base frame 2 has two stands 7, 8, which are each designed as U-shaped profiles. In the stator 7, a gear motor 9 is arranged, through which the swing frame 3 can be pivoted about its pivot axis 6. Another geared motor 10 serves to pivot the Mischgutstrom-generating device 4 about the pivot axis 5 within the swing frame 3. By the motors 9, 10, the Mischgutstrom-generating device 4 can be pivoted due to their gimbal storage within the respective range of motion in any spatial position.

Die Mischgutstrom-Erzeugungseinrichtung 4 verfügt über einen Elektromotor 11, auf dessen Antriebswelle 12 ein propellerartig konzipiertes Mischwerkzeug 13 angeordnet ist. Die Flügel 14, 14.1 des Mischwerkzeuges 13 sind gegenüber der Mischwerkzeugnabe 15 klappbar. In Figur 1 befinden sich sind die Flügel 14, 14.1 in ihrer gegenüber der Mischwerkzeugnabe 15 abgeklappten Lage, in der die Längsachsen der Flügel 14, 14.1 parallel oder in etwa parallel zur Längsachse der Antriebswelle 12 verlaufen. Die radiale Erstreckung des Mischwerkzeuges 13 ist in der in Figur 1 gezeigten Stellung seiner Flügel 14, 14.1 daher wesentlich geringer als in der Benutzungsstellung, in der die Flügel 14, 14.1 ausgeschwenkt sind. Die abklappbare Konzeption der Flügel 14, 14.1 des Mischwerkzeuges 13 gestattet ein Einführen des Mischwerkzeuges 13 in einen Mischbehälter mit einer im Durchmesser relativ kleinen oberen Öffnung, die beispielsweise als Mannloch konzipiert sein kann.The mixed material flow generating device 4 has an electric motor 11, on whose drive shaft 12 a propeller-like designed mixing tool 13 is arranged. The wings 14, 14.1 of the mixing tool 13 are opposite the Mischwerkzeugnabe 15 hinged. In FIG. 1 are located the wings 14, 14.1 in its opposite the Mischwerkzeugnabe 15 folded down position in which the longitudinal axes of the wings 14, 14.1 parallel or approximately parallel to the longitudinal axis of the drive shaft 12. The radial extent of the mixing tool 13 is in the in FIG. 1 shown position of its wings 14, 14.1 therefore much lower than in the use position in which the wings 14, 14.1 are swung. The hinged design of the wings 14, 14.1 of the mixing tool 13 allows insertion of the mixing tool 13 in a mixing container with a relatively small diameter upper opening, which may be designed, for example, as a manhole.

Der Mischgutstrom-Erzeugungseinrichtung 4 ist eine bei dem dargestellten Ausführungsbeispiel zwei Anschlussarme 16, 16.1 aufweisende als Hubeinrichtung konzipierte Anschlusseinrichtung zugeordnet. Die Anschlussarme 16, 16.1 dienen zum Anschließen eines Mischbehälters 17 an die Mischvorrichtung 1. Als Mischbehälter 17 ist bei dem in Figur 1 dargestellten Ausführungsbeispiel ein herkömmlicher Schüttgutcontainer mit eckiger Umfangsgeometrie vorgesehen. Der Mischbehälter 17 verfügt oberseitig über eine als Befüll- und Reinigungsöffnung konzipierte Öffnung 18. Diese dient zum Befüllen des Mischbehälters 17 mit dem zu mischenden Schüttgut, bei dem es sich beispielsweise um Kunststoffgranulate handeln kann. Der Mischbehälter 17 weist des Weiteren eine nicht näher dargestellte unterseitige, mit einem Verschluss versehene Abzugsöffnung auf, über die der Mischbehälter 17 entleert werden kann. Der Mischbehälter 17 verfügt über ein rahmenartig ausgebildetes Mischbehältergestell 19. Das Mischbehältergestell 19 kann stapelbar konzipiert sein. Teil des Mischbehältergestells 19 sind zwei mit Abstand zueinander angeordnete, den unteren Abschluss bei dem dargestellten Ausführungsbeispiel bildende Streben 20, 20.1. Diese sind an allen vier Seiten des Mischbehältergestells 19 angeordnet. Die Streben 20, 20.1 sind mit Abstand zueinander angeordnet und definieren durch ihren Abstand jeweils eine Aufnahme 21, 21.1. Die Aufnahmen 21, 21.1 dienen zur Aufnahme jeweils eines, einem jeden Anschlussarm 16 bzw. 16.1 zugeordneten Kupplungsgliedes 22, 22.1. Der Mischbehälter 17 ist mit seinem Mischbehältergestell 19 und seinen Streben 20, 20.1 zwischen die beiden Anschlussarme 16, 16.1 mit ihren darin angeordneten Kupplungsgliedern 22, 22.1 eingeschoben worden. Die Kupplungsglieder 22, 22.1 sind jeweils angeschlossen an eine Spannstange 23, 23.1, mit denen diese translatorisch mit den Spannstangen 23, 23.1 bewegt werden können. Angetrieben sind die Spannstangen 23, 23.1 jeweils durch einen getrieblich untersetzten Elektromotor 24, 24.1. Die Spannstangen 23, 23.1 sind gehalten und geführt in den U-förmig konzipierten Anschlussarmen 16, 16.1, die zueinander weisend offen ausgeführt sind. Mit der als Hubvorrichtung ausgebildeten Anschlusseinrichtung, können Mischbehälter bzw. Mischbehältergestelle, Container oder andere Behälter, in denen sich zu mischendes Gut befindet, unterschiedlicher Bauhöhe an die Mischgutstrom-Erzeugungseinrichtung 4 angeschlossen werden.The Mischgutstrom-generating device 4 is assigned in the illustrated embodiment, two connecting arms 16, 16.1 designed as a lifting device connecting device. The connecting arms 16, 16. 1 serve to connect a mixing container 17 to the mixing device 1 FIG. 1 illustrated embodiment, a conventional bulk container provided with angular peripheral geometry. The mixing container 17 has on the upper side an opening 18 designed as a filling and cleaning opening. This container serves to fill the mixing container 17 with the bulk material to be mixed, which may be plastic granules, for example. The mixing container 17 further includes a non-illustrated lower side, provided with a closure exhaust port through which the mixing container 17 can be emptied. The mixing container 17 has a frame-like designed mixing container frame 19. The mixing container frame 19 may be designed to be stackable. Part of the mixing container frame 19 are two mutually spaced, forming the lower end in the illustrated embodiment struts 20, 20.1. These are arranged on all four sides of the mixing container frame 19. The struts 20, 20.1 are arranged at a distance from each other and define by their distance in each case a receptacle 21, 21.1. The receptacles 21, 21.1 serve to receive one, each connecting arm 16 or 16.1 associated coupling member 22, 22.1. The mixing container 17 has been inserted with its mixing container frame 19 and its struts 20, 20.1 between the two connecting arms 16, 16.1 with their coupling members 22, 22.1 arranged therein. The coupling members 22, 22.1 are each connected to a tension rod 23, 23.1, with which they can be moved translationally with the tension rods 23, 23.1. The tension rods 23, 23.1 are each driven by a geared geared electric motor 24, 24.1. The tension rods 23, 23.1 are held and guided in the U-shaped connecting arms 16, 16.1, which are designed to be open to each other. With the connecting device designed as a lifting device, mixing containers or mixing container racks, containers or other containers in which the material to be mixed is located can be connected to the mixed material flow generating device 4 of different height.

Die Kupplungsglieder 22, 22.1 hintergreifen somit den Mischbehälter 17 formschlüssig in ihrer Bewegungsrichtung an einem durch den jeweils oberen Streb 20 gebildeten Absatz. Werden die Spannstangen 23, 23.1 zum Anschließen des Mischbehälters 17 an die Mischvorrichtung 1 bzw. die Mischgutstrom-Erzeugungseinrichtung 4 heran bewegt, wird der Mischbehälter 17 in Richtung zur Mischgutstrom-Erzeugungseinrichtung 4 angehoben. Im Zuge dieser Bewegung wird das Mischwerkzeug 13 durch die oberseitige Öffnung 18 in das Innere des Mischbehälters 17 eingeführt. Zum Verschließen der Öffnung 18 des Mischbehälters 17 verfügt die Mischgutstrom-Erzeugungseinrichtung 4 über ein plattenartiges Verschlusselement 25, welches auf dem oberen, flanschartig ausgebildeten Abschluss 26 der Öffnung 18 anliegt, wenn der Mischbehälter 17 bestimmungsgemäß an die Mischgutstrom-Erzeugungseinrichtung 4 angeschlossen ist. Das Verschlusselement 25 liegt sodann, unter einer bestimmten Vorspannung stehend an dem Abschluss 26 der Öffnung 18 an. Bei dem dargestellten Ausführungsbeispiel ist in das Verschlusselement 25 ein Dichtring 27 eingelegt (vgl. Figur 2). Der Mischwerkzeug 13 ist von der zu dem Mischbehälter 17 weisenden Seite Verschlussplatte 25 abragend vorgesehen.The coupling members 22, 22.1 thus engage behind the mixing container 17 in a form-fitting manner in its direction of movement on a shoulder formed by the respective upper strut 20. If the tension rods 23, 23.1 are moved toward the mixing device 1 or the mixed material flow generating device 4 for connecting the mixing container 17, the mixing container 17 is raised in the direction of the mixed material flow generating device 4. In the course of this movement, the mixing tool 13 is inserted through the upper-side opening 18 into the interior of the mixing container 17. For closing the opening 18 of the mixing container 17, the mixed material flow generating device 4 has a plate-like closure element 25 which rests on the upper, flange-shaped closure 26 of the opening 18 when the mixing container 17 is intended connected to the Mischgutstrom-generating device 4. The closure element 25 is then, under a certain bias standing at the end 26 of the opening 18 at. In the illustrated embodiment, a sealing ring 27 is inserted into the closure element 25 (see. FIG. 2 ). The mixing tool 13 is provided protruding from the side facing the mixing container 17 side closure plate 25.

Zum Durchführen des eigentlichen Mischprozesses wird nach Anschließen des Mischbehälters 17 an die Mischgutstrom-Erzeugungseinrichtung 4 der Schwenkrahmen 3 verschwenkt, sodass die Einheit, gebildet aus Mischgutstrom-Erzeugungseinrichtung 4 und Mischbehälter 17, sich in einer Überkopfanordnung befindet. Typischerweise wird der Mischvorgang bei der Mischvorrichtung 1 begonnen, wenn der Schwenkrahmen 3 um 180° geschwenkt worden ist.To carry out the actual mixing process, the swivel frame 3 is pivoted after connecting the mixing container 17 to the Mischgutstrom-generating means 4, so that the unit formed of Mischgutstrom-generating device 4 and mixing container 17, is located in an overhead assembly. Typically, the mixing process is started in the mixing device 1, when the swing frame 3 has been pivoted by 180 °.

Diese Überkopfanordnung ist schematisiert in einem Ausschnitt in Figur 2 gezeigt. Durch die Überkopfanordnung ist das in dem Mischbehälter 17 enthaltene, zu mischende Mischgut auf den zuvor oberen und nunmehr unteren Abschluss des Mischbehälters 17 gefallen, sodass das Mischwerkzeug 13 von Mischgut umgeben ist. Durch die um 180° geschwenkte Anordnung haben sich die Flügel 14, 14.1 schwerkraftbedingt ausgeklappt und sind in dieser, in Figur 2 gezeigten Stellung, durch einen an der Mischwerkzeugnabe 13 angeordneten Anschlag gehalten. Der Mischbehälter 17 ist unter der von der Anschlusseinrichtung bereitgestellten Vorspannung in der in Figur 2 gezeigten Stellung mit dem Abschluss 26 seiner Mündung 18 gegen das plattenartige Verschlusselement 25 bzw. die darin eingelegte Dichtung 27 wirkend gehalten.This overhead arrangement is schematized in a cutout in FIG FIG. 2 shown. Due to the overhead arrangement, the mixture to be mixed contained in the mixing container 17 has fallen to the previously upper and now lower end of the mixing container 17, so that the mixing tool 13 is surrounded by mix. Due to the swung by 180 ° arrangement, the wings 14, 14.1 unfolded by gravity and are in this, in FIG. 2 shown position, held by a arranged on the Mischwerkzeugnabe 13 stop. The mixing container 17 is below the bias voltage provided by the connection device in the in FIG. 2 shown position with the end 26 of its mouth 18 against the plate-like closure member 25 and the inserted therein seal 27 acting.

Zum Starten des Mischvorganges wird der Elektromotor 11 bestromt, sodass das als Propeller 13 ausgebildete Mischwerkzeug in Rotation versetzt wird. Dabei ist vorgesehen, das Mischwerkzeug 13 mit einer solchen Geschwindigkeit anzutreiben, dass das innerhalb des Mischbehälters 17 befindliche Mischgut zur Ausbildung eines Mischgutstromes bewegt wird. Bei Einsatz eines Mischwerkzeuges, wie in den Figuren gezeigt, bildet sich ein Mischthrombus aus.To start the mixing process, the electric motor 11 is energized, so that the mixing tool designed as a propeller 13 is set in rotation. It is provided to drive the mixing tool 13 at such a speed that the mixing material contained within the mixing container 17 is moved to form a Mischgutstromes. When using a mixing tool, as shown in the figures, a Mischthrombus forms.

Figur 3 zeigt den Mischbehälter 17 in seiner Überkopfanordnung und somit in seiner Mischstellung an die Mischgutstrom-Erzeugungseinrichtung 4 angeschlossen, jedoch im Unterschied zu der Darstellung der Figur 2 mit einem Verschlusselement 25' gemäß der Erfindung. Im Unterschied zu dem Verschlusselement 25 ist das Verschlusselement 25' in die Öffnung 18 des Mischbehälters 17 eingreifend konzipiert und zwar dergestalt, dass das in den Behälter 17 eingreifende Abschluss des Verschlusselementes 25' bündig mit dem Innenraum des Behälters abschließt. Das Verschlusselement 25' trägt an seinem in das Behälterinnere weisenden Ende einen in radialer Richtung wirkenden Dichtring 27'. Dieser wirkt gegen die Innenseite der Öffnung des Mischbehälters 17. Zum erleichterten Einführen des Verschlusselementes 25' in die Öffnung 18 des Mischbehälters 17 handelt es sich bei dem Dichtring 27' um eine bezüglich ihrer Dichtwirkung aktivierbare Dichtung, etwa eine pneumatisch oder hydraulisch aktivierbaren Dichtring, wie in dieser Figur vorgesehen. Die Aktivierungseinrichtung zum Aktivieren (Befüllen bzw. Entleeren) des Dichtringes 27 sind in der Figur nicht dargestellt. Bei der in Figur 3 gezeigten Konzeption ist eine Ausbildung von Todräumen vermieden. FIG. 3 shows the mixing container 17 in its overhead arrangement and thus in its mixing position connected to the Mischgutstrom-generating device 4, but in contrast to the representation of FIG. 2 with a closure element 25 'according to the invention. In contrast to the closure element 25, the closure element 25 'is designed to engage in the opening 18 of the mixing container 17 in such a way that the closure of the closure element 25' engaging in the container 17 terminates flush with the interior of the container. The closure element 25 'carries at its pointing into the container interior end acting in the radial direction of a sealing ring 27'. This acts against the inside of the opening of the mixing container 17. For facilitated insertion of the closure element 25 'in the opening 18 of the mixing container 17 is at the sealing ring 27' with respect to their sealing action activatable seal, such as a pneumatically or hydraulically activated sealing ring, such as provided in this figure. The activation device for activating (filling or emptying) of the sealing ring 27 are not shown in the figure. At the in FIG. 3 shown conception of death spaces is avoided.

Im Hinblick auf das Verschlusselement 25' ist darauf hinzuweisen, dass dieses lediglich in Bezug auf seine den unteren Abschluss des Mischbehälters 17 in seiner Figur 3 gezeigten Stellung bildende Seite zu reinigen ist, da sämtliche anderen Abschnitte dieses Verschlusselementes 25' nicht in Kontakt mit dem in dem Mischbehälter 17 befindlichen Mischgut stehen.With regard to the closure element 25 'is to be noted that this is only in relation to its the lower end of the mixing container 17 in his FIG. 3 shown position to clean side is because all other portions of this closure element 25 'are not in contact with the mixture in the mixing container 17 are.

Da es sich bei dem Mischbehälter 17 um einen Schüttgutcontainer handelt, der eine quadratische Querschnittsgeometrie aufweist, ist die Innenkontur dieses Mischbehälters 17 entsprechend quadratisch. Dieses bedeutet, dass der Mischbehälter 17 im Bereich seiner Ecken über Bereiche verfügt, in denen sich Mischgut akkumulieren kann. Dieser Umstand wird bei dem Mischprozess genutzt, um diesen zu verbessern. Die kardanische Aufhängung der Mischgutstrom-Erzeugungseinrichtung 4 und des daran für die Durchführung des Mischprozesses angeschlossenen Mischbehälters 17, erlaubt es, dass der Mischbehälter 17 während des Mischprozesses um die Schwenkachsen 5, 6 verschwenkt werden kann. Auf diese Weise kann der Mischbehälter 17, wie beispielsweise in Figur 3 gezeigt, in unterschiedliche Raumlagen gebracht werden. Die Erzeugung des thrombusartigen Mischstroms im Inneren des Mischbehälters 17 bleibt durch die Rotation des Mischwerkzeuges 13 aufrechterhalten. Das Verschwenken des Mischbehälters 17 hat zur Folge, dass in Abhängigkeit von seiner Raumlage in den Ecken so genannte Mischtodzonen entstehen, in denen Mischgut akkumuliert und zunächst nicht mehr an dem Mischprozess weiter teilnimmt, jedenfalls so lange nicht, bis der Mischbehälter 17 in eine Raumlage gebracht worden ist, dass das in einem solchen Bereich akkumulierte Mischgut schwerkraftbedingt herausfällt. Dieses Herausfallenlassen von in einer solchen Todzone akkumulierten Mischgutes führt zu einer Erzeugung von Querturbulenzen innerhalb des Mischgutstromes, was wiederum den Vorgang des Durchmischens unterstützt. Dieses ausnutzend, kann eine wirksame bestimmungsgemäße Durchmischung auch bei kleineren Drehzahlen des Mischwerkzeuges 13 erfolgen, was sich wiederum günstig auf eine nicht gewünschte Erwärmung sowie ein schonendes Mischen des Mischgutes beim Vorgang des Mischens auswirkt.Since the mixing container 17 is a bulk material container which has a square cross-sectional geometry, the inner contour of this mixing container 17 is correspondingly square. This means that the mixing container 17 in the region of its corners has areas in which mix can accumulate. This circumstance is used in the mixing process to improve it. The cardanic suspension of the mixed material flow generating device 4 and the mixing container 17 connected thereto for carrying out the mixing process, allows the mixing container 17 to be pivoted about the pivot axes 5, 6 during the mixing process. In this way, the mixing container 17, such as in FIG. 3 shown to be placed in different spatial positions. The generation of the thrombus-like mixed flow in the interior of the mixing container 17 is maintained by the rotation of the mixing tool 13. The pivoting of the mixing container 17 has the result that, depending on its spatial position in the corners so-called Mischtodzonen arise in which accumulates and initially no longer participates in the mixing process, at least not until the mixing container 17 brought into a spatial position has been that the accumulated in such a range mix falls by gravity. This dropout of mixed material accumulated in such a dead zone results in the generation of transverse turbulence within the mix stream, which in turn aids the blending process. Utilizing this advantage, effective thorough mixing can take place even at lower rotational speeds of the mixing tool 13, which in turn has a favorable effect on undesirable heating and gentle mixing of the mixed material during the mixing process.

Figur 4 zeigt die Mischvorrichtung 1 mit dem daran angeschlossenen Mischbehälter 17 in einer um die Achsen 5, 6 verschwenkten und gegenüber der Vertikalen geneigten Raumlage. Der Mischbehälter 17 ist, wie in Figur 3 durch die beispielhaft dargestellten Bewegungsbahnen 28 schematisiert gekennzeichnet in alle Richtungen verschwenkbar. Eine Bewegung des Mischbehälters 17 mit der daran angeschlossenen Mischgutstrom-Erzeugungseinrichtung 4 erfolgt in Abhängigkeit von der Innengeometrie des Mischbehälters 17 und/oder dem darin enthaltenen Mischgut. Eine Verstellbarkeit der Raumlage der aus Mischgutstrom-Erzeugungseinrichtung 4 und Mischbehälter 17 gebildeten Einheit erfolgt entsprechend einem vorgegebenen Bewegungsprotokoll. Das Bewegungsprotokoll kann konzipiert sein, dass der Mischbehälter 17 eine konstante Neigung aufweist und um den Schnittpunkt der Schwenkachsen 5, 6 herum bewegt wird. Gleichfalls ist es möglich, mit der Mischvorrichtung 1 den Mischbehälter 17 entlang einer Ebene in eine auch dreidimensional vorgesehene Pendelbewegung zu versetzen. Durch die kardanische Aufhängung kann das Bewegungsprotokoll den jeweiligen Anforderungen entsprechend konzipiert sein und Pendelbewegungen in beliebige Richtungen mit geraden und/oder kreisförmigen Bahnenbewegungen verbinden, wenn gewünscht. FIG. 4 shows the mixing device 1 with the mixing container 17 connected thereto in a about the axes 5, 6 pivoted and inclined relative to the vertical space position. The mixing container 17 is, as in FIG. 3 characterized schematically by the motion paths 28 exemplified in all directions pivotally. A movement of the mixing container 17 with the mixed material flow generating device 4 connected thereto is effected as a function of the internal geometry of the mixing container 17 and / or the mixed material contained therein. An adjustability of the spatial position of the Mischgutstrom-generating device 4 and mixing container 17 formed unit is carried out according to a predetermined movement protocol. The movement protocol may be designed so that the mixing container 17 has a constant inclination and is moved around the intersection of the pivot axes 5, 6. Likewise, it is possible with the mixing device 1 to move the mixing container 17 along a plane in a three-dimensionally provided pendulum movement. The cardanic suspension allows the motion log to be designed to meet the requirements of each, and to associate pendulum motion in any direction with straight and / or circular path motions, if desired.

Nach Beenden des Mischvorganges wird der Mischbehälter 17 in seine Ausgangsposition zurückgeschwenkt und von der Mischgutstrom-Erzeugungseinrichtung 4 durch Lösen der Anschlussmittel getrennt.After completion of the mixing process, the mixing container 17 is pivoted back to its original position and separated from the Mischgutstrom-generating device 4 by loosening the connection means.

Soll anschließend ein Mischgut mit einer anderen Zusammensetzung mit der Mischvorrichtung 1 gemischt werden, braucht lediglich das Verschlusselement 25 und das Mischwerkzeug 13 gereinigt zu werden. Das andere Mischgut wird in seinem Transportcontainer herangeführt, in diesem wie vorstehend beschrieben gemischt und anschließend der weiteren Verwendung zugeführt.If a mixture having a different composition is subsequently mixed with the mixing device 1, only the closure element 25 and the mixing tool 13 need to be cleaned. The other mix is introduced in its transport container, mixed in this as described above and then supplied for further use.

Die vorbeschriebene Aufhängung der Mischgutstrom-Erzeugungseinrichtung macht deutlich, dass an diese grundsätzlich jedes Behältnis, in dem ein zu mischendes Schüttgut enthalten ist, an die Mischgutstrom-Erzeugungseinrichtung 4 angeschlossen werden kann. Insbesondere bedarf es nicht notwendigerweise eines Umfüllens des zu mischenden Mischgutes in einen eigens konzipierten Mischbehälter. Hierbei kann es sich auch um Säcke oder dergleichen handeln. Diese werden für den Vorgang des Mischens an einem entsprechend konzipierten Mischbehältergestell aufgehängt.The above-described suspension of the Mischgutstrom-generating device makes it clear that this basically every container in which a bulk material to be mixed is contained, can be connected to the Mischgutstrom-generating device 4. In particular, it does not necessarily require a transfer of the mixing material to be mixed in a specially designed mixing container. These may also be bags or the like. These are hung for the process of mixing on a suitably designed mixing vessel rack.

Für den Fall, dass der Abstand der Mischwerkzeuge von dem zum Verschließen der Mischbehälteröffnung vorgesehenen Verschlusselement relativ groß ist und/oder für den Fall, dass das oder die Mischwerkzeuge relativ tief in den Mischbehälter eingebracht werden sollen, kann vorgesehen sein, dass die Mischgutstrom-Erzeugungseinrichtung in Richtung der Längsachse der die Werkzeuge tragenden Antriebswelle im Bezug auf den Mischbehälter verstellbar ist. Eine solche Verstelleinheit 29 ist schematisiert in in Figur 5a wiedergegeben. Die Verstelleinheit 29 ist Teil einer im Übrigen nicht näher dargestellten Mischvorrichtung, die ebenso konzipiert ist wie die Mischvorrichtung 1 der Figuren 1 bis 4. Die Verstelleinheit 29 ist an ein Rahmenteil 30 angeschlossen, das um eine der Schwenkachse 5 der Mischvorrichtung 1 entsprechende Schwenkachse 5 schwenkbar ist. Abgebildet in Figur 5a ist die Montageplatte 31 mit dem Elektromotors E, der auf der Montageplatte 31 aufsitzt. Der Elektromotor E treibt die unterseitig aus der Verstelleinheit 29 austretende Antriebswelle 32 an, an deren freiem Ende das oder die Mischwerkzeuge angeordnet sind (in Figuren 5a, 5b nicht dargestellt). Der Elektromotor bildet mit seiner Flanschplatte 31 und einem zylindrischen Führungskörper F eine Baueinheit. Diese vorbeschriebene Baueinheit ist in einem zylindrischen Führungsring 33 in der durch den Doppelblockpfeil gekennzeichneten Richtung verstellbar. Figur 5a zeigt die Verstelleinheit 29 in ihrer abgesenkten Stellung, bei der die auf der Antriebswelle 32 sitzenden Mischwerkzeug am Tiefsten in einen an die Verstelleinheit 29 angeschlossenen Mischbehälter (nicht dargestellt) eingreifen. Angeschlossen an die aus Elektromotor E, Montageplatte 31 und innerhalb des Führungsrings 33 beweglichem Führungskörper F nebst Antriebswelle 32 umfassende Baueinheit sind bei dem dargestellten Ausführungsbeispiel zwei Spindeltriebe 34, 34.1, die für die Verstellung der vorbeschriebenen Baueinheit verantwortlich sind. Die Spindeltriebe 34, 34.1 sind jeweils durch einen Elektromotor (nicht dargestellt) angetrieben. An die gegenüber dem Führungsring 33 verstellbare Montageplatte 31 sind in radialer Richtung zwei sich radial erstreckende Laschen 35, 35.1 vorgesehen, die wiederum an den jeweiligen Spindelantrieb 34 bzw. 34.1 angeschlossen sind. Bei einem Betrieb der Spindeltriebe 34, 34.1 zum Bewegen der verstellbaren Baueinheit gegenüber dem Führungsring 33 wird diese Baueinheit in die ein oder andere Richtung bewegt, je nachdem, in welcher Richtung der Spindelantrieb angetrieben ist. Figur 5b zeigt die Verstelleinheit 29 in ihrer gegenüber der Stellung in Figur 5a angehobenen Stellung. In dieser Stellung sind die auf der Antriebswelle 32 sitzenden Mischwerkzeuge in Richtung zu der Öffnung des Mischbehälter oder je nach Konzeption des Mischbehälters aus diesem herausbewegt worden.In the event that the distance of the mixing tools from the closure element provided for closing the mixing container opening is relatively large and / or in the event that the mixing tool or tools are to be introduced relatively deep into the mixing container, can be provided be that the Mischgutstrom-generating device in the direction of the longitudinal axis of the tool-carrying drive shaft with respect to the mixing container is adjustable. Such an adjustment unit 29 is shown schematically in FIG FIG. 5a played. The adjusting unit 29 is part of a mixing device, not otherwise illustrated, which is designed as well as the mixing device 1 of FIGS. 1 to 4 , The adjusting unit 29 is connected to a frame part 30 which is pivotable about a pivot axis 5 corresponding to the pivot axis 5 of the mixing device 1. Pictured in FIG. 5a is the mounting plate 31 with the electric motor E, which is seated on the mounting plate 31. The electric motor E drives the drive shaft 32 emerging from the adjustment unit 29 on the underside, at the free end of which the mixing tool or tools are arranged (in FIG FIGS. 5a, 5b not shown). The electric motor forms with its flange plate 31 and a cylindrical guide body F a structural unit. This above-described unit is adjustable in a cylindrical guide ring 33 in the direction indicated by the double block arrow direction. FIG. 5a shows the adjustment unit 29 in its lowered position, in which the sitting on the drive shaft 32 mixing tool at the lowest in a mixing unit connected to the adjustment 29 (not shown) engage. Connected to the electric motor E, mounting plate 31 and within the guide ring 33 movable guide body F together with the drive shaft 32 comprehensive unit are in the illustrated embodiment, two spindle drives 34, 34.1, which are responsible for the adjustment of the above-described unit. The spindle drives 34, 34.1 are each driven by an electric motor (not shown). At the opposite the guide ring 33 adjustable mounting plate 31 are two radially extending tabs 35, 35.1 are provided in the radial direction, which in turn are connected to the respective spindle drive 34 and 34.1. In an operation of the spindle drives 34, 34.1 for moving the adjustable unit relative to the guide ring 33, this unit is moved in one or the other direction, depending on the direction in which the spindle drive is driven. FIG. 5b shows the adjusting unit 29 in its opposite to the position in FIG. 5a raised position. In this position, sitting on the drive shaft 32 mixing tools have been moved out in the direction of the opening of the mixing container or depending on the design of the mixing container out of this.

Unter Verwendung einer Verstelleinheit 29 oder einer mit derselben Funktionalität ist es möglich, die Bauhöhe einer Mischvorrichtung, auch eines solchen, wie zu den Figuren 1 bis 4 beschrieben, zu reduzieren. Dieses ermöglicht, dass der notwendige Hub zum Anschließen eines Mischbehälters an das Verschlusselement grundsätzlich nur ein kleineren Hubbetrag ausüben muss, da das Einbringen der Mischwerkzeuge in den Mischbehälter durch die Verstelleinheit zumindest teilweise übernommen werden kann. Gleichermaßen eignet sich das Vorsehen einer solchen Verstelleinheit auch dann, wenn im Unterschied zu dem Mischverfahren, wie zu der Mischvorrichtung der Figur 1 beschrieben, nicht in einer Überkopfstellung gemischt werden soll, sondern für den Mischvorgang der Mischbehälter in seiner ursprünglichen Position, verbleibt, und es sodann erforderlich ist, dass das oder die Mischwerkzeuge bis in den Bereich des Bodens eingefahren werden.Using an adjusting unit 29 or one with the same functionality, it is possible to increase the overall height of a mixing device, even one such as the FIGS. 1 to 4 described, reduce. This allows that the necessary stroke for connecting a mixing container to the closure element basically only has to exercise a smaller amount of lift, since the introduction of the mixing tools can be at least partially taken over by the adjustment in the mixing container. Likewise, the provision of such an adjustment unit is also suitable if, in contrast to the mixing method, as to the mixing device of FIG. 1 described, not to be mixed in an overhead position, but for the mixing process of the mixing container in its original position, remains, and then it is necessary that the mixing tool or are retracted to the area of the bottom.

Es versteht sich, dass das beschriebene Mischwerkzeug mit seinen auch unabhängig von der in diesen Ausführungen konkret beschriebenen Anwendung eingesetzt werden kann.It is understood that the mixing tool described can be used with its independent of the application specifically described in these embodiments.

Ohne den Umfang der Ansprüche zu verlassen, ergeben sich für einen Fachmann zahlreiche weitere Ausgestaltungsmöglichkeiten für die beanspruchte Mischvorrichtung. Beispielsweise können Zentriermittel vorgesehen sein, mit denen die oberseitige Öffnung eines Mischbehälters an die Mischgutstrom-Erzeugungseinrichtung angeschlossen werden können. Bei solchen Zentriermitteln kann es sich beispielsweise auch um solche handeln, die eine konische Verjüngung aufweisen und in die Öffnung des Mischbehälters hineingreifen.Without departing from the scope of the claims, numerous further design possibilities for the claimed mixing device will be apparent to a person skilled in the art. For example, centering means can be provided, with which the top-side opening of a mixing container can be connected to the Mischgutstrom-generating device. Such centering means may, for example, also be those which have a conical taper and reach into the opening of the mixing container.
