Description

Die Erfindung betrifft ein Mischgerät zum Mischen von sich in einem Behälter befindenden fliessfähigen Massen, mit einem Dreharm, auf dem wenigstens ein Behälterträger mit Behälter peripher mit zum Zentrum des Dreharms geneigter Rotationsachse angeordnet ist und einem Antrieb zum Erzeugen einer Drehbewegung des Dreharms sowie einer Drehbewegung des Behälterträgers um seine Rotationsachse entgegengesetzt der Drehrichtung des Dreharms.The invention relates to a mixing device for mixing those located in a container flowable masses, with a swivel arm on which at least one Container carrier with peripheral container inclined to the center of the rotating arm Axis of rotation is arranged and a drive for generating a rotary movement of the rotating arm and a rotary movement of the container carrier around its Rotation axis opposite to the direction of rotation of the rotating arm.

In vielen Bereichen der Industrie, des Handwerks und des Handels stellt sich das Problem, eine Vielzahl von Anmischungen schnell und jederzeit zur Verfügung zu haben, um damit verschiedene Arbeiten durchführen zu können. Der Industrie, dem Handwerk und dem Handel sowie aus Gründen der Lagerstabilität ist es wirtschaftlich und technisch unmöglich, die Vielzahl der erforderlichen Anmischungen, sei es in bezug auf Sonderfarben oder bestimmte Zusammensetzungen zu bevorraten. Meist werden deshalb Standardmassen gekauft und, je nach Bedarf, entsprechend modifiziert. Dies geschieht durch Zugabe von Farbpasten, Füllstoffen, Weichmachern, Vernetzern, Katalysatoren usw.This is the case in many areas of industry, trade and commerce Problem, a variety of mixes available quickly and at all times in order to be able to carry out various tasks. The industry, the It is craft and trade as well as for reasons of storage stability economically and technically impossible, the multitude of required Mixtures, be it in relation to special colors or certain ones Stock compositions. This is why standard masses are usually used bought and modified as needed. This is done by adding of color pastes, fillers, plasticizers, crosslinking agents, catalysts, etc.

Bei den Anmischungen kann es sich um ein- und mehrkomponentige, flüssige und pastöse Massen handeln, die heute als Kleber, Verguss-, Abguss-, Beschichtungs- oder Dichtmasse im Einsatz sind. Derartige Massen reagieren in der Regel nach dem Applizieren zu festen, gel- oder gummiartigen Produkten. Speziell mehrkomponentige Massen müssen vor der Applizierung gut gemischt werden.The blends can be single and multi-component, liquid and pasty masses, which today act as glue, casting, pouring, coating or Sealant are in use. Such masses usually react the application to solid, gel or rubber-like products. Specifically multicomponent masses must be mixed well before application.

Insbesondere zum Einsatz im Dentalbereich sind Mischgeräte zum Erzeugen derartiger Anmischungen bekannt, welche einen um eine Achse rotierenden Dreharm aufweisen, wobei auf diesem Dreharm im Umfangsbereich ein zum Zentrum des Dreharmes geneigter Behälterträger angeordnet ist, der ebenfalls um seine Rotationsachse, jedoch entgegengesetzt der Drehrichtung des Dreharmes angetrieben ist.Mixing devices are particularly suitable for use in the dental field of such mixtures are known, which rotate around an axis Have rotary arm, with a rotary arm in the circumferential area to Center of the rotary arm inclined container carrier is arranged, which also around its axis of rotation, but opposite to the direction of rotation of the rotating arm is driven.

Die WO 92/06777 zeigt und beschreibt eine als "Planeten-Zentrifugalmischer" bezeichnete Vorrichtung, bei der auf einem um eine senkrechte Rotationsachse drehbaren Dreharm in diametral gegenüberliegenden Bereichen im wesentlichen zylindrische Mischbehälter angeordnet sind, die sich ihrerseits um schräg zur Rotationsachse geneigte Achsen drehen. In der Beschreibung wird ausgeführt, daß es mit dieser Vorrichtung möglich sei, zwei verschiedene Mischungen gleichzeitig herzustellen oder eine Mischung in zwei Portionen zu unterteilen.WO 92/06777 shows and describes a "planetary centrifugal mixer" designated device in which on a around a vertical axis of rotation rotatable swivel arm in diametrically opposite areas essentially cylindrical mixing containers are arranged, which in turn rotate about axes inclined to the axis of rotation. In the description states that it is possible with this device, two different ones Prepare mixtures at the same time or a mixture in two To divide portions.

Die DE-OS 20 01 301 offenbart eine ähnliche Vorrichtung, zeigt jedoch auch eine Ausführungsform, bei der auf einem Dreharm in radialem Abstand zur Rotationsachse des Dreharmes nur ein geneigter Mischbehälter angeordnet ist. Zum Ausgleich der auf den Mischbehälter ausgeübten Fliehkräfte wird an der gegenüberliegenden Seite des Dreharmes ein Gegengewicht in Verbindung mit einer radial einstellbaren Madenschraube vorgesehen.DE-OS 20 01 301 discloses a similar device, but also shows an embodiment in which on a rotary arm at a radial distance from Rotation axis of the rotating arm only arranged an inclined mixing container is. To compensate for the centrifugal forces exerted on the mixing container, a counterweight is connected to the opposite side of the rotary arm provided with a radially adjustable grub screw.

Die EP-A 0 402 668 zeigt eine Vorrichtung mit nur einem Mischbehälter auf der einen Seite der Rotationsachse eines Dreharms und einer als Block schematisch dargestellten Unwucht-Ausgleichsmasse auf der gegenüberliegenden Seite des Dreharms, bezogen auf die Rotationsachse.EP-A 0 402 668 shows a device with only one mixing container one side of the axis of rotation of a rotating arm and one schematically as a block Imbalance compensation mass shown on the opposite Side of the rotating arm, related to the axis of rotation.

Der Erfindung liegt die Aufgabe zugrunde, ein Mischgerät zu schaffen, dessen Auswuchtelement derart ausgebildet ist, dass ein Ausgleich des Massenschwerpunktes bei jeder Drehzahl des Dreharmes herrscht, so dass das Unwuchtverhalten verhindert wird. The invention has for its object to provide a mixer, the Balancing element is designed such that a balance of the center of gravity at every speed of the rotating arm, so that the unbalance behavior is prevented.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß auf dem Dreharm diametral gegenüber dem Behälterträger ein Gehäuse fest angebracht ist, das ebenfalls schräg zur Rotationsachse des Dreharms geneigt angeordnet ist, und daß sich in dem Gehäuse eine aktive Ausgleichsmasse befindet, die in bezug auf Dichte und Volumen so gewählt ist, daß die resultierenden Fliehkräfte des Behälterträgers mit Behälter einerseits und des Gehäuses mit aktiver Ausgleichsmasse andererseits im Gleichgewicht stehen.According to the invention the object is achieved in that on the rotary arm diametrically a housing is firmly attached to the container carrier, which is also inclined to the axis of rotation of the rotating arm, and that there is an active balancing mass in the housing which is related on density and volume is chosen so that the resulting centrifugal forces the container carrier with container on the one hand and the housing with active Balance mass on the other hand are in balance.

Durch die Anordnung einer aktiven Ausgleichsmasse erfolgt ein Auswuchten des Mischgerätes. Somit entstehen bei der Betriebsdrehzahl und während der Beschleunigungsphase keine Auswuchtprobleme.By arranging an active The mixing device is balanced out. Thus arise at the Operating speed and no balancing problems during the acceleration phase.

Zweckmässigerweise liegt die aktive Ausgleichsmasse auf dem gleichen Durchmesser wie der Behälterträger mit Behälter. In einem solchen Fall sind beide auf dem Dreharm angeordneten Behälter gleich schwer ausgebildet und einander diametral gegenüberliegend angeordnet. The active one expediently lies Leveling compound on the same diameter as the container carrier Container. In such a case, both are arranged on the swivel arm Containers of equal weight and diametrically opposite each other arranged.

Die aktive Ausgleichsmasse wird durch ein in einem Gehäuse angeordnetes fliessfähiges Medium gebildet. Ein derartiges Gehäuse ist drehfest bzw. starr an dem Dreharm angeordnet. Das Gehäuse erfährt somit nur die Drehung des Dreharmes und kann aus Platzgründen wesentlich kleiner ausgebildet sein. Das Volumen der Ausgleichsmasse kann gegenüber der zu mischenden Masse kleiner sein, wenn die Ausgleichsmasse eine höhere Dichte aufweist, als die aktive Masse. Eine derartige aktive Ausgleichsmasse hält den Dreharm bei sich ändernden Drehzahlen während der An- und Auslaufphase und bei konstanten Drehzahlen im ausgewuchteten Zustand. Durch die Verlagerung des Massenschwerpunktes dieses Mediums bei unterschiedlichen Drehzahlen wird der Dreharm ausgewuchtet. Speziell im konstanten Drehzahlbereich während des Mischvorganges wird auf diese Weise darauf geachtet, dass die Auswuchtung während der Mischzeit bei konstanter Drehzahl optimal ist.The active balancing mass is in a housing arranged flowable medium formed. Such a housing is non-rotatable or rigidly arranged on the rotary arm. The housing only experiences rotation of the rotary arm and can be made much smaller for reasons of space. The Volume of the balancing mass can be smaller compared to the mass to be mixed be when the balancing mass has a higher density than the active mass. Such an active balancing mass keeps the rotating arm from changing Speeds during the start and stop phase and at constant speeds in balanced state. By shifting the center of gravity of this Medium at different speeds, the rotating arm is balanced. Specifically in the constant speed range during the mixing process In this way, care was taken to ensure that the balance was constant during the mixing time Speed is optimal.

Vorteilhafterweise ist das fliessfähige Medium kleinkörniges Schüttgut. Kleinkörniges Schüttgut besitzt die Eigenschaften, sich fliessartig bewegen zu können, um auf diese Art den Massenschwerpunkt allmählich zu verlagern.The flowable medium is advantageously small-grain bulk material. Grainy Bulk goods have the properties of being able to move smoothly in order to this way of gradually shifting the center of gravity.

Die Erfindung wird anhand eines Ausführungsbeispiels näher erläutert.

The invention is explained in more detail using an exemplary embodiment.
Fig. 1
shows a schematic representation of a mixing device according to the invention with container carrier and housing partially cut;

Das in der Fig. 1 dargestellte Mischgerät weist einen als Drehplatte 2 ausgebildeten Dreharm auf, auf dem ein Behälterträger 1 mit Behälter 4 und ein Gehäuse 3 angeordnet sind, wobei das Gehäuse 3 dem Behälterträger 1 mit Behälter 4 diametral gegenüberliegt. Sowohl der Behälterträger 1, der Behälter 4 als auch das Gehäuse 3 sind schräg zueinander angeordnet. Die Neigung um den Winkel A des Behälterträgers 1 und des Gehäuses 3 gegenüber einer Senkrechten, bezogen auf die horizontal angeordnete Drehplatte 2, kann beispielsweise 35° betragen. Je nach Mischvorgang und abhängig von der zu mischenden Masse liegt dieser Winkel A etwa zwischen 15° und 45°.The mixing device shown in FIG. 1 has a rotary plate 2 Swivel arm on which a container carrier 1 with container 4 and a housing 3rd are arranged, the housing 3 the container carrier 1 with container 4th diametrically opposite. Both the container carrier 1, the container 4 and that Housing 3 are arranged obliquely to each other. The inclination by the angle A of the Container carrier 1 and the housing 3 with respect to a vertical, based on the horizontally arranged rotating plate 2 can be, for example, 35 °. Depending on Mixing process and depending on the mass to be mixed is this angle A approximately between 15 ° and 45 °.

Der Behalterträger 1 mit Behälter 4 ist gegenüber der Drehplatte 2 derart gelagert, dass eine Rotation des Behälterträgers 1 um seine eigene Achse stattfinden kann. Eine entsprechende Lagereinrichtung 5 ist fest mit der Drehplatte 2 verbunden. Der Behälterträger 1 weist eine nicht dargestellte Antriebswelle auf, die mit einem Winkelgetriebe 6 zusammenwirkt, welches von einem auf der Unterseite der Drehplatte 2 angeordneten Zahnriementrieb 7 angetrieben wird. Dieser Zahnriementrieb 7 steht in Verbindung mit einem ersten Abtrieb des Getriebes 8, das dem Antriebsmotor 9 vorgelagert ist. Das Getriebe 8 besitzt einen zweiten Abtrieb mit einer anderen Drehzahl wie der erste Abtrieb und dient dem Antrieb der Drehplatte 2, die für den Mischvorgang in Drehbewegung versetzt werden muss.The container carrier 1 with the container 4 is mounted relative to the rotary plate 2 in such a way that that the container carrier 1 can rotate about its own axis. A corresponding bearing device 5 is firmly connected to the rotary plate 2. Of the Container carrier 1 has a drive shaft, not shown, which with a Angular gear 6 cooperates, which one on the underside of the rotary plate 2 arranged toothed belt drive 7 is driven. This timing belt drive 7 is in connection with a first output of the transmission 8, which the Drive motor 9 is upstream. The transmission 8 has a second output a different speed than the first output and serves to drive the rotary plate 2, which must be rotated for the mixing process.

Der auf der Drehplatte 2 angeordnete Behälterträger 1 mit Behälter 4 führt während des Mischvorganges eine Rotationsbewegung aus, die allerdings gegenläufig zur Drehrichtung der Drehplatte 2 ist. Die Drehzahlen des Behälterträgers 1 und der Drehplatte 2 sind unterschiedlich. Während des Mischvorganges dreht sich die Drehplatte 2 etwa doppelt so schnell wie der Behälterträger 1.The arranged on the rotary plate 2 container carrier 1 with container 4 leads during of the mixing process from a rotational movement, which, however, in the opposite direction Direction of rotation of the rotating plate 2 is. The speeds of the container carrier 1 and Turntable 2 are different. The turns during the mixing process Turntable 2 about twice as fast as the container carrier 1.

Das auf der Drehplatte 2 angeordnete Gehäuse 3 ist über einen Zwischenflansch 3c mit der Drehplatte 2 starr verbunden.The housing 3 arranged on the rotary plate 2 is via an intermediate flange 3c rigidly connected to the rotary plate 2.

Das ganze Mischgerät wird von einem Gestell 10 gehalten. Aus Sicherheitsgründen ist die gesamte rotierende Drehplatte 2 während des Mischvorganges mit einer aufklappbaren Haube 11 abgedeckt. Mittels eines nicht dargestellten Sicherheitsschalters wird die Inbetriebnahme des Mischgerätes verhindert, so lange die Haube 11 geöffnet ist.The entire mixing device is held by a frame 10. For safety reasons is the entire rotating turntable 2 during the mixing process with a hinged hood 11 covered. By means of a safety switch, not shown commissioning of the mixer is prevented as long as the hood 11 is open.

Der Behälterträger 1 ist im wesentlichen auf den Durchmesser des Behälters 4 abgestimmt. Entsprechend abgestimmte, nicht dargestellte Einsätze machen es möglich, in einen grossen Behälterträger 1 auch kleinere Behälter 4 einzusetzen. Der in der Fig. 1 dargestellte Behälter 4 trägt einen abnehmbaren Deckel 4c. The container carrier 1 is essentially of the diameter of the container 4 Voted. Appropriately coordinated inserts, not shown, do it possible to use smaller containers 4 in a large container carrier 1. The container 4 shown in FIG. 1 carries a removable lid 4c.

Da sich die in dem Behälter 4 befindliche Masse 4a während des Mischvorganges in jene Richtung verlagert, in die die Fliehkraft wirkt, muss darauf geachtet werden, dass der Behälter mit entsprechend wenig Masse 4a angefüllt wird, so dass nicht allzuviel Masse 4a während des Mischvorganges gegen den Deckel 4c des Behälters 4 drückt.Since the mass 4a in the container 4 is in during the mixing process the direction in which the centrifugal force acts must be taken into account that the container is filled with correspondingly little mass 4a, so that not too much mass 4a during the mixing process against the lid 4c Container 4 presses.

Das dem Behälterträger 1 diametral gegenüberliegende Gehäuse 3 ist bezüglich der Höhe des Behälterträgers 1 derart angeordnet, dass der Massenschwerpunkt der sich in dem Gehäuse 3 befindlichen Ausgleichsmasse 3a während des Mischvorganges auf gleicher Höhe zu liegen kommt, wie der Massenschwerpunkt der zu mischenden Masse 4a im Behälter 4. Die Ausgleichsmasse 3a in dem Gehäuse 3 besteht aus einem fliessfähigen Medium, das im vorliegenden Falle aus kleinkörnigen Bleikugeln besteht. Die Masse 4a sowie die Ausgleichsmasse 3a bilden während des Mischvorganges paraboloide Oberflächen 4d, 3d.The housing 3 diametrically opposite the housing 3 is in relation to the Height of the container carrier 1 arranged such that the center of gravity of the located in the housing 3 balancing mass 3a during the Mixing process is at the same level as the center of gravity the mass to be mixed 4a in the container 4. The balancing mass 3a in the Housing 3 consists of a flowable medium, which in the present case small-grained lead balls. The mass 4a and the balancing mass 3a form parabolic surfaces 4d, 3d during the mixing process.

Abhängig von dem Gewicht bzw. der Dichte der zu mischenden Masse 4a muss die Ausgleichsmasse 3a über die Dichte abgestimmt werden, so dass einerseits über das Füllvolumen der entsprechende Massenschwerpunkt erreicht wird und andererseits über die Dichte ein Ausgleich der Masse 4a, 3a stattfindet. Bei Inbetriebnahme des Mischgerätes muss das ganze System ausgewuchtet sein.Depending on the weight or density of the mass 4a to be mixed, the Compensating mass 3a to be matched to the density, so that on the one hand over the filling volume the corresponding center of mass is reached and on the other hand A compensation of the mass 4a, 3a takes place via the density. When starting up of the mixer, the entire system must be balanced.

Das Gehäuse 3 ist mit einem abnehmbaren Deckel 3b versehen, so dass die Ausgleichsmasse 3a entsprechend der zu mischenden Masse 4a angepasst werden kann.The housing 3 is provided with a removable cover 3b, so that the Compensating mass 3a can be adjusted according to the mass 4a to be mixed can.
