Die Erfindung betrifft einen Mischer mit einem Schwingantrieb für einen beweglich gelagerten Objektträger gemäß dem Oberbegriff von Anspruch 1. Ein solcher Mischer ist z.B. in der Schrift WO-A-91 16 127 offenbart.The invention relates to a mixer with a vibratory drive for a movably mounted slide according to the preamble of claim 1. Such a mixer is e.g. in WO-A-91 16 127.

Mischer sind in verschiedenen Ausführungen bekannt. Mischer mit einem Rührwerk haben den Nachteil, daß sie mechanisch auf die Mikrostruktur des zu rührenden Mediums einwirken und dadurch Zerstörungen, z. B. von biologischen Systeme hervorrufen können. Zu Mischern der eingangs beschriebenen Gattung, die mit Schwingantrieben arbeiten, gehören auch Schüttelbehälter, die in einer bzw., wie in WO-A-91 16 127, in zwei Richtung in eine schwingende Bewegung gesetzt werden, oder rotierende Behälter. Diese Mischer arbeiten bei Frequenzen bis zu ca. 20 Hz. Daneben gibt es Ultraschallmischer, die bei Frequenzen oberhalb von 20 Khz arbeiten.Mixers are known in various designs. mixer with an agitator have the disadvantage that they are mechanical on the microstructure of the medium to be stirred act and thereby destruction, z. B. of biological Systems can cause. To mixers of those described at the beginning Genus that work with vibratory drives also include shaker containers that are in one or, as in WO-A-91 16 127, in two Direction in a swinging movement can be set, or rotating Container. These mixers operate at frequencies up to approx. 20 Hz. There are also ultrasonic mixers, that work at frequencies above 20 kHz.

Aufgabe der Erfindung ist es, einen Mischer der eingangs beschriebenen Gattung anzugeben, der dreidimensionale Schwingbewegungen bei Frequenzen bis zu 20 Khz ausführen kann.The object of the invention is a mixer of the beginning Specify described genus, the three-dimensional Carry out oscillating movements at frequencies up to 20 kHz can.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelost. Ein derartiger Mischer eignet sich insbesondere zum Einsatz in verschiedenen Labors für die verschiedensten Mischzwecke. Da die nach dem Prinzip eines Gleichstrom-Linearmotors ausgebildeten Schwingantriebe jeweils nur in einer räumlichen Richtung arbeiten und nach Frequenz und Amplitude angesteuert werden können, lassen sich die Betriebsparameter des Mischers ohne Schwierigkeiten den jeweiligen Erfordernissen anpassen.This object is achieved by the features of claim 1. Such a mixer is suitable are particularly suitable for use in various laboratories the most diverse mixing purposes. Because the principle a direct current linear motor trained vibratory drives only work in one spatial direction at a time and can be controlled according to frequency and amplitude, can be the operating parameters of the mixer without Adapt difficulties to the respective requirements.

Bevorzugt ist eine Ausführung, bei der die Y-Federn und die X-Federn als Blattfedern ausgebildet sind. Insbesondere können der Y-Rahmen und der X-Rahmen einen rechteckigen bis quadratischen Grundriß aufweisen, wobei ihre zugeordneten Blattfedern jeweils an einander gegenüberliegende Seiten der Rahmen angeschlossen sind. Abgesehen von Federverlusten ist damit eine praktische reibungsfreie Lagerung bzw. Abstützung möglich. Es versteht sich, daß die Federn so ausgelegt seien sollten, daß sie die durch den permanentmagnetischen Fluß des betreffenden Schwingantriebes hervorgerufene Anziehungskraft aufnehmen können, ohne daß dadurch die gewünschte richtungsabhängige Federauslenkung beeinträchtigt wird. An embodiment is preferred in which the Y springs and the X-springs are designed as leaf springs. Especially the Y frame and the X frame can be rectangular to have a square floor plan, with their assigned Leaf springs each on opposite sides Sides of the frame are connected. Except for spring losses is a practical, frictionless storage or support possible. It is understood that the springs should be designed in such a way that the permanent magnetic Flow of the vibratory drive in question attraction can take up without thereby the desired direction-dependent spring deflection is affected.

Beim erfindungsgemäßen Mischer, bei dem der X-Rahmen auf zumindest einer in Z-Richtung auslenkbaren Z-Feder abgestützt ist, die an einen in Z-Richtung beweglichen Z-Rahmen angeschlossen ist, wobei am Z-Rahmen zumindest ein Schwingantrieb angreift ist zur Stabilisierung des Objektträgers der Objektträger über Scharniere mit sich in X-Richtung erstreckende Scharnierachse an eine in Z-Richtung auslenkbare, mit dem Y-Rahmen verbundene Federplatte angeschlossen, wobei an diese Scharniere auch der Z-Rahmen über in Y-Richtung auslenkbare Federbleche angeschlossen ist.In the mixer according to the invention, in which the X frame is at least a Z spring deflectable in the Z direction is supported, connected to a Z-frame that can move in the Z-direction is, at least one oscillating drive on the Z-frame attacks to stabilize the slide the slide over hinges with hinge axis extending in the X direction to a Spring plate deflectable in the Z direction and connected to the Y frame connected, being attached to these hinges the Z frame also has spring plates that can be deflected in the Y direction connected.

Nach bevorzugter Ausführung der Erfindung kann zumindest eine Einrichtung zur Veränderung der Federkonstanten vorgesehen werden. Dabei kann es sich um eine Einrichtung zur zweidimensionalen Veränderung der Federkonstante aus einem einseitig eingespannten Federstab und einer längs des Federstabs verstellbaren Masse handeln, oder um eine Einrichtung zur eindimensionalen Veränderung der Federkonstante aus einem einseitig eingespannten Federstab oder aus einer einseitig eingespannten Blattfeder, der bzw. die in einer parallel dazu verstellbaren Gabel geführt ist, wobei die Gabel in einem neben dem Federstab bzw. der Blattfeder angeordneten Gehäuse geführt und mit einem Stelltrieb, insbesondere Spindeltrieb, verstellbar ist. Die genaue Einstellbarkeit des Resonanzpunktes über die Veränderung der Federkonstanten gestattet es, bei unterschiedlich bewegten Massen des auf dem Objektträgers angeordneten Mediums innerhalb eines bestimmten Bereiches immer mit optimalen Wirkungsgrad zu arbeiten.According to a preferred embodiment of the invention, at least a device for changing the spring constant is provided will. This can be a facility for two-dimensional change of the spring constant from one spring bar clamped on one side and one along the spring bar adjustable mass, or a device for one-dimensional change of the spring constant from a spring bar clamped on one side or from a leaf spring clamped on one side, the or is guided in a fork that can be adjusted parallel to it, the fork in a next to the spring bar or the Leaf spring arranged housing and with a Actuator, especially spindle drive, is adjustable. The exact adjustability of the resonance point over the Changing the spring constant allows it to be different moving masses of the arranged on the slide Medium within a certain range always to work with optimal efficiency.

Im einzelnen kann eine Einrichtung zur eindimensionalen Veränderung der Federkonstante zumindest an einer X-Feder des X-Rahmens angreifen. Bei anderen Ausführungen kann zwischen dem X-Rahmen bzw. dem Y-Rahmen und einer Grundplatte eine Einrichtung zur Veränderung der Federkonstante angeordnet sein, wobei der Federstab an der Grundplatte oder einem damit verbundenen Bauteil eingespannt und in einem Gelenklager des Y-Rahmens geführt ist.In particular, a device for one-dimensional Change the spring constant at least on an X spring of the X frame. With other versions can between the X frame or the Y frame and a base plate a device for changing the spring constant be arranged, the spring rod on the base plate or a connected component and clamped in a hinge bearing of the Y-frame is guided.

Eine Verstellung des Resonanzpunktes in Z-Richtung ist möglich, wenn zwischen dem Z-Rahmen und einer Grundplatte eine Einrichtung zur Veränderung der Federkonstante angeordnet ist, wobei der sich horizontal erstreckende Federstab an der Grundplatte oder einem damit verbundenen Bauteil eingespannt und in einem Gelenklager des Z-Rahmens geführt ist.There is an adjustment of the resonance point in the Z direction possible if between the Z-frame and a base plate arranged a device for changing the spring constant is, the horizontally extending spring rod on the base plate or a component connected to it clamped and in a spherical bearing of the Z-frame is led.

Die Schwingantriebe sollten unabhängig voneinander nach Frequenz, Amplitude und Phase steuer- und/oder regelbar sein. Durch Nachregeln können die richtungsabhängigen Schwingantriebe so eingestellt werden, daß sie immer mit optimalen Wirkungsgrad arbeiten.The vibratory drives should follow independently of each other Frequency, amplitude and phase can be controlled and / or regulated be. By adjusting the directional Vibratory drives can be set so that they are always with work at optimum efficiency.

Wenn ferner eine Einrichtung zum Erfassen der Betriebsparameter der einzelnen Schwingantriebe in Abhängigkeit von der Zeit vorgesehen wird, kann der Mischer auch für weitere Zwecke eingesetzt werden, z. B. zur Viskositätsbestimmung der zu behandelnden Medien. Zu dieser Einrichtung können in die Wicklungen der Schwingantriebe integrierte Meßschleifen oder dergl. und nachgeschaltete Regel- und Steuervorrichtungen gehören. Man kann auch die sich während des Mischens ändernde Viskosität eines Mediums über die Veränderung des Trägheitsmomentes und die sich damit einstellende Verschiebung des Resonanzpunktes erfassen. Der nachzustellende Betrag zumindest eines Betriebsparameters des oder der Schwingantriebe bis zum Auffinden des neuen Resonanzpunktes ist dann ein Maß für die Viskositätsänderung.If further a means for detecting the operating parameters of the individual vibratory drives depending on the time is provided, the mixer can also be used for others Purposes are used, e.g. B. for viscosity determination the media to be treated. About this facility can be integrated in the windings of the vibratory drives Measuring loops or the like. And downstream control and Control devices include. You can also see the while of mixing changing viscosity of a medium about the change in the moment of inertia and the itself thus detecting the shifting of the resonance point. The amount to be adjusted at least one operating parameter the or the vibratory drives until they can be found the new resonance point is then a measure of the change in viscosity.
