Description
Die vorliegende Erfindung betrifft eine Mischvorrichtung zum Vermischen von flüssigen, fließfähigen oder pulverförmigen Materialien, mit einem drehbar gelagerten ersten Bauteil, mit einem drehbar an dem ersten Bauteil gelagerten zweiten Bauteil, mit einer Antriebseinrichtung zur Erzeugung einer Drehbewegung des ersten Bauteils, und mit einer Umlenkeinrichtung zur Übertragung und Umlenkung einer Drehbewegung des ersten Bauteils auf das zweite Bauteil, derart, daß eine Drehrichtung des ersten Bauteils entgegengesetzt zu der Drehrichtung des zweiten Bauteils ist.The present invention relates to a mixing device for mixing liquid, flowable or powdery materials, with a rotatably mounted first component, with a rotatably mounted on the first component second component, with a drive device for generating a rotational movement of the first component, and with a deflection device for Transmission and deflection of a rotational movement of the first component to the second component, such that a direction of rotation of the first component is opposite to the direction of rotation of the second component.
Eine solche Mischvorrichtung ist aus dem Stand der Technik (z.B. JP-A-63310629) zum Vermischen von Pasten mit Pasten, Pasten mit Pulvern oder Pulver mit Pulvern usw. bekannt. Typische Einsatzgebiete solcher Mischvorrichtungen zum Stand der Technik sind die Anmischung von Dichtstoffen und Beschichtungsmitteln (wie zum Beispiel Silikonen, Polyurethanen und Acrylaten), Lacken, Druckfarben und Pigmenten sowie das Vermischen von Ein-, Zwei- oder Multikomponenten Produkten in flüssiger oder pastöser Form.Such a mixing apparatus is known in the art (e.g., JP-A-63310629) for blending pastes with pastes, pastes with powders or powders with powders, and the like. Typical applications of such prior art mixing devices are the admixture of sealants and coating agents (such as silicones, polyurethanes and acrylates), paints, printing inks and pigments as well as the mixing of one-, two- or multi-component products in liquid or pasty form.
Solche Mischvorrichtungen des Standes der Technik sind kompakt ausgebildet, teilweise mobil und an wechselnden Standorten einsetzbar. Die Mischvorrichtungen sind zudem ohne Ausnahme nur für Substanzmengen zwischen 5 g und 300 g geeignet. Größere Mengen können mit Mischvorrichtungen der Eingangs genannten Art nicht verarbeitet werden. Ein Grund dafür ist, daß die Umlenkung der Drehrichtung, also die Initiierung einer zueinander entgegengesetzten Drehbewegung der beiden drehbar gelagerten Bauteile, über ein Wellengelenk erfolgt. Aufgrund des für den Stand der Technik relevanten Anwendungsbereichs müssen die Mischvorrichtungen zum Beispiel in Zahnarztpraxen, Dentallabors und dergleichen einsatzfähig sein. Die Mischvorrichtungen sind daher in Bezug auf ihre Größe, auf ihr Gewicht und somit auch in Bezug auf ihr Wellengelenk auf ein bestimmtes Maß beschränkt. Eine Auslegung der Mischvorrichtung des Standes der Technik für größere Verarbeitungsmengen hätte die Folge, daß auf die für solche Mischvorrichtungen zur Verfügung stehenden Wellengelenke eine zu große Kraftwirkung ausgeübt würde, welche diese schnell zerstören. Die Auswahl größerer Wellengelenke wiederum würde zu sehr großen Mischvorrichtungen führen, welche aus diesem Grunde nicht für jeden Einsatzort geeignet wären.Such mixing devices of the prior art are compact, partially mobile and can be used in changing locations. The mixing devices are also without exception only for substance quantities between 5 g and 300 g suitable. Larger quantities can not be processed with mixing devices of the type mentioned above. One reason for this is that the deflection of the direction of rotation, that is, the initiation of a mutually opposite rotational movement of the two rotatably mounted components, via a universal joint. Because of the area of application relevant to the prior art, the mixing devices must be able to be used, for example, in dental practices, dental laboratories and the like. The mixing devices are therefore limited to a certain extent in terms of their size, their weight and thus also with respect to their shaft joint. An interpretation of the prior art mixing apparatus for larger amounts of processing would have the consequence that too much force would be exerted on the shaft joints available for such mixing devices, which destroy them quickly. The choice of larger joints in turn would be very large Mixing devices lead, which would not be suitable for this reason for every job site.
Ein weiterer, mit dem Einbau von Wellengelenken verbundene Nachteil ist, daß ein Anstellwinkel zwischen dem ersten Bauteil und dem zweiten Bauteil nur um 8 Grad veränderbar ist. Der Anstellwinkel übt aber einen Einfluß auf die Mischwirkung aus. Aus diesem Grunde kann über den begrenzten Einstellwinkel auch nur ein begrenzter Einfluß auf die Mischwirkung ausgeübt werden.Another disadvantage associated with the installation of shaft joints is that an angle of attack between the first component and the second component can only be changed by 8 degrees. The angle of attack exerts an influence on the mixing effect. For this reason, only a limited influence on the mixing effect can be exerted on the limited setting angle.
Darüber hinaus hat eine Mischvorrichtung zum Stand der Technik auch den Nachteil, daß eine Geschwindigkeitsregulierung der Drehgeschwindigkeit des ersten Bauteils und des zweiten Bauteils nur sehr aufwendig durchzuführen ist.In addition, a mixing device of the prior art also has the disadvantage that a speed regulation of the rotational speed of the first component and the second component is very expensive to perform.
Die Aufgabe der vorliegenden Erfindung ist, eine Mischvorrichtung zum Vermischen von flüssigen, fließfähigen oder pulverförmigen Materialien der Eingangs genannten Art so weiter zu bilden, daß diese unabhängig von ihrer Größe für nahezu beliebig große Verarbeitungsmengen geeignet ist und die Mischwirkung in Abhängigkeit an die zu mischenden Materialien in einfacher Weise beeinflußt werden kann.The object of the present invention is to form a mixing device for mixing liquid, flowable or powdery materials of the type mentioned so on that it is suitable regardless of their size for almost any large amounts of processing and the mixing effect depending on the materials to be mixed can be influenced in a simple manner.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Umlenkeinrichtung wenigstens ein axiales Umlenkelement und wenigstens ein radiales Umlenkelement aufweist, die über ein flexibles Riemenelement untereinander und mit der Antriebseinrichtung und dem zweiten Bauteil wirkverbunden sind.The object is achieved in that the deflection device has at least one axial deflecting element and at least one radial deflecting element, which are operatively connected via a flexible belt element with each other and with the drive device and the second component.
Durch die erfindungsgemäße Ausbildung der Umlenkeinrichtung ist es möglich, eine Umlenkung einer Drehbewegung auch relativ großen Gewichten auf dem zweiten Bauteil dauerhaft und betriebssicher durchzuführen. Die einzelnen Bauteile können robust ausgebildet werden und in Ihrer Anordnung bedarfsweise variiert werden, um nahezu beliebige Kraftwirkungen ohne Störung der Betriebsfunktion aufzunehmen. Weiterhin ist es durch eine geeignete Anordnung der einzelnen Bauelemente der Umlenkeinrichtung zueinander und durch Wahl ihrer jeweiligen Ausbildung möglich, im Rahmen einfacher physikalischer Überlegungen die Drehgeschwindigkeiten des ersten und des zweiten Bauteils und somit der Relativgeschwindigkeiten zueinander zu variieren.The inventive design of the deflection, it is possible to perform a deflection of a rotational movement and relatively large weights on the second component permanently and reliable. The individual components can be made robust and, if necessary, can be varied in their arrangement in order to absorb virtually any force effects without disturbing the operating function. Furthermore, it is possible by a suitable arrangement of the individual components of the deflection device to each other and by choosing their respective training to vary the rotational speeds of the first and second component and thus the relative velocities to each other within simple physical considerations.
Darüber hinaus ist durch eine geeignete Anordnung der einzelnen Bauteile der Umlenkeinrichtung möglich, einen Anstellwinkel zwischen dem ersten Bauteil und dem zweiten Bauteil nahezu beliebig zwischen 0 und 90° auszubilden, um dadurch Einfluß auf eine zu erzielende Mischwirkung auszuüben.In addition, by a suitable arrangement of the individual components of the deflection device is possible to form an angle between the first component and the second component almost anywhere between 0 and 90 °, thereby exerting influence on a mixing effect to be achieved.
Weitere Vorteile ergeben sich aus den Merkmalen der Unteransprüche 2 bis 12.Further advantages result from the features of the subclaims 2 to 12.

Zur Festlegung ist aber auch jedes andere im Stand der Technik bekannte Befestigungsmittel verwendbar.On the
Der Dreharm 5 kann eine beliebige Grundform haben. In der vorliegenden Ausführungsform hat der Dreharm 5 zwei Schenkel 5.1 und 5.2. Der Schenkel 5.1 erstreckt sich in einer vertikalen Ebene durch die Drehachse D1 mit einer Hauptachse in einem Winkel, dem sogenannten Anstellwinkel, zwischen 0 und 90° radial zur Drehachse D1 der Welle 7. An einer entsprechend angewinkelten, und senkrecht zu der vertikalen Ebene ausgerichteten Oberfläche 5.3 des Schenkels 5.1 ist ein zweites Bauteil 11 drehbar gelagert und weist eine Drehachse D2 auf.The rotary arm 5 may have any basic shape. In the present embodiment, the rotary arm 5 has two legs 5.1 and 5.2. The leg 5.1 extends in a vertical plane through the axis of rotation D1 with a major axis at an angle, the so-called Angle of attack, between 0 and 90 ° radially to the axis of rotation D1 of the shaft 7. At a correspondingly angled, and oriented perpendicular to the vertical plane surface 5.3 of the leg 5.1, a
Das zweite Bauteil 11 ist als Mischbecher zur Aufnahme eines Mischgutes ausgebildet. Aufgrund der Winkelstellung des Schenkels 5.1 ergibt sich eine Winkelbeziehung zwischen der Drehachse D1 des ersten Bauteils 5 und der Drehachse D2 des zweiten Bauteils 11. Der Umfang des zweiten Bauteils 11 ist bodenseitig, das heißt, an dem Ende des zweiten Bauteils 11, welches der Oberfläche 5.3 des Schenkels 5.1 entgegen gerichtet ist, als Keilriemenscheibe 13 ausgebildet und ist somit drehfest mit dem zweiten Bauteil 11 verbunden. Die Keilriemenscheibe 13 hat einen zur Drehachse D2 konzentrische, radiale Wirkfläche 13 mit keilförmigen Vertiefungen.The
An dem Dreharm 5 ist auf der Seite des Schenkels 5.1 ein erstes axiales Umlenkelement 15 angeordnet, welches drehbar an dem Dreharm 5 gelagert ist. Die Drehachse des ersten Umlenkelements 15 verläuft in der vorliegenden Ausführungsform parallel zur Drehachse D1. Das erste Umlenkelement 15 hat eine zu seiner Drehachse konzentrische, radiale glatte Wirkfläche 15.1, welche in einer horizontalen Ebene mit der Wirkfläche 9.1 der Keilriemenscheibe 9 liegt. In Figur 1 liegt nicht sichtbar, hinter dem ersten axialen Umlenkelement 15 ein zweites axiales Umlenkelement 15, das genauso wie das erste axiale Umlenkelement 15 ausgebildet ist und in der gleichen Beziehung zu der Keilriemenscheibe 9 und deren Wirkfläche 9.1 liegt. Die beiden Umlenkelemente 15 sind symmetrisch zu der Keilriemenscheibe 9 angeordnet. In einer Draufsicht stellt eine gedachte Verbindung zwischen den Drehachsen der beiden Umlenkelemente 15 und der Drehachse D1 ein gleichseitiges Dreieck dar, wobei die gedachte Verbindung zwischen den beiden Drehachsen der Umlenkelemente 15 eine Grundseite dieses Dreiecks bildet.On the rotary arm 5, a first axial deflecting
An der Unterseite des Dreharms 5 im Bereich des Schenkels 5.2 ist auch ein radiales Umlenkelement 17 angeordnet. Das radiale Umlenkelement 17 hat eine in der vorliegenden Ausführungsform im wesentlichen horizontale Drehachse und eine dazu konzentrische, radiale, glatte Wirkfläche. Die radiale Wirkfläche trifft an einer Stelle eine gedachte horizontale Mittelebene der Wirkfläche 9.1 der Keilriemenscheibe 9. In Fig. 1 ist direkt hinter dem radialen Umlenkelement 17, auf der anderen Seite des Dreharms 5, ein zweites axiales Umlenkelement 17 angeordnet. Auch dieses zweite axiale Umlenkelement 17 ist genauso ausgebildet, wie das dargestellte axiale Umlenkelement 17 und steht in der gleichen Beziehung zu der Keilriemenscheibe 9 und deren Wirkfläche 9.1. Die beiden radialen Umlenkelemente 17 sind symmetrisch zu der Drehachse D1 angeordnet.At the bottom of the rotary arm 5 in the region of the leg 5.2 and a
In Fig. 2 ist schematisch der Umlenkmechanismus dargestellt. Der Umlenkmechanismus wird durch eine Umlenkeinrichtung gebildet, die sich in der vorliegenden Ausführungsform aus der erste Keilriemenscheibe 9, den zwei axialen Umlenkelementen 15, den zwei radialen Umlenkelementen 17 und der Keilriemenscheibe 13 zusammensetzt. Die vorgenannten Bauteile der Umlenkeinrichtung sind über ein als Keilriemen ausgebildetes flexibles Riemenelement 19 miteinander wirkverbunden. Der endlos ausgebildete Keilriemen 19 greift mit seinen Keilen in die Vertiefungen der Wirkfläche 9.1 der Keilriemenscheibe 9 ein, verläuft mit seiner glatten Unterseite um einen Teilumfang der Wirkflächen 15.1 der beiden axialen Umlenkelemente 15 und, ebenfalls mit seiner glatten Seite, um einen Teilumfang der Wirkfläche 17.1 der radialen Umlenkelemente 17 und schließlich mit seiner Keilseite um einen Teilumfang der Wirkfläche 13.1 der Keilriemenscheibe 13. Mit Drehung des Dreharms 5 um die Drehachse D1 wird die Drehbewegung über die Umlenkeinrichtung auf das zweite Bauteil 11, den Mischbecher, in einer entgegen gesetzte Drehbewegung übertragen.In Fig. 2, the deflection mechanism is shown schematically. The deflection mechanism is formed by a deflection device which in the present embodiment comprises the first V-belt pulley 9, the two
In Figur 2 sind die Drehachsen D1 und D2 in ihrer Winkelbeziehung zueinander und die Durchmesser der Bauteile der Umlenkeinrichtung dargestellt. Durch eine geeignete Wahl der Winkelbeziehung zwischen D1 und D2 und durch eine geeignete Wahl der Durchmesser, können, je nach Mischgut, unterschiedliche Drehgeschwindigkeiten eingestellt werden, ohne daß sich das grundlegende Bauprinzip verändert. Mit der beschriebenen Umlenkeinrichtung gemäß vorliegender Erfindung erfolgt regelmäßig eine Untersetzung der Drehgeschwindigkeit des ersten Bauteils 5 zum zweiten Bauteil 11. Es ist theoretisch aber auch möglich in geeigneten Fällen die Umlenkeinrichtung so zu gestalten, daß eine Übersetzung erfolgt. Es ist auch möglich, daß die Umlenkeinrichtung mehr als zwei axiale und/oder radiale Umlenkelemente 15, 17 aufweist. Auch können zwischen den axialen Umlenkeichrichtungen 15 und den radialen Umlenkeinrichtungen 17 und zwischen den radialen Umlenkeinrichtungen 17 und der Keilriemenscheibe 13 weitere Umlenkeinrichtungen vorgesehen sein, deren Wirkflächen Winkelpositionen zwischen denjenigen der Wirkflächen 15.1, 17.1 und 13.1 annehmen, um den Keilriemen 19 führend zu stützen.In Figure 2, the axes of rotation D1 and D2 are shown in their angular relationship to each other and the diameter of the components of the deflection device. By a suitable choice of the angular relationship between D1 and D2 and by a suitable choice of the diameter, depending on the mix, different rotational speeds can be set without changing the basic design principle.
