Description

TECHNISCHES GEBIETTECHNICAL AREA

Die Erfindung betrifft ein Verfahren zur Umwandlung einer kontinuierlichen rotatorischen Bewegung in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende translatorische Bewegung, eine Anwendung des Verfahrens, eine Vorrichtung zur Durchführung des Verfahrens, eine Einbaubohle eines Strassenfertigers umfassend eine solche Vorrichtung sowie einen Strassenfertiger mit der Einbaubohle gemäss den Oberbegriffen der unabhängigen Patentansprüche.The invention relates to a method for converting a continuous rotary motion into a translational motion that continuously reverses with respect to its direction of movement, an application of the method, a device for carrying out the method, a screed of a road paver comprising such a device and a paver with the screed according to FIGS Preambles of the independent claims.

STAND DER TECHNIKSTATE OF THE ART

Die Umwandlung einer kontinuierlichen rotatorischen Bewegung in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende translatorische Bewegung stellt ein in der Technik häufig anzutreffendes Bedürfnis dar. Dies unter anderem deshalb, weil mechanische Energie heute in vielen Fällen am besten mittels kontinuierlich rotierender Kraftmaschinen, z.B. Verbrennungs-, Hydraulik- oder Elektromotoren, in rotatorischer Form zur Verfügung gestellt werden kann und sodann, wenn damit eine sich fortlaufend widerholende translatorische Arbeit verrichtet werden soll, entsprechend umgewandelt werden muss.The conversion of a continuous rotational motion into a translational motion continuously reversing in its direction of motion is a need frequently encountered in the art. This is because, among other things, mechanical energy is best achieved in many cases by means of continuously rotating power machines, e.g. Combustion, hydraulic or electric motors, can be provided in rotary form and then, if so that a repetitive repetitive translational work is to be performed, must be converted accordingly.

So stellt sich zum Beispiel bei Einbaubohlen von Strassenfertigern, mit welchen die frisch ausgelegte Asphaltdecke vor dem Überwalzen vorverdichtet wird, die Aufgabe, die fortlaufende Aufwärts- und Abwärtsbewegung der Stampferleiste der Einbaubohle möglichst verlustfrei und mit einer einfachen und robusten mechanischen Lösung aus einer von einem Elektro- oder Hydraulikmotor bereitgestellten kontinuierlichen Rotationsbewegung abzuleiten und dabei eine möglichst gleichmässige Belastung des Antriebsmotors zu erreichen. Zudem ist es wünschenswert, dass der Hub der Stampferleiste eingestellt werden kann, um verschiedenen Einbausituationen/Asphaltdicken optimal Rechnung tragen zu können, wobei es weiter von Vorteil ist, wenn der untere Totpunkt beim Verstellen unverändert bleibt.Thus, for example, in screeds of asphalt pavers, with which the freshly designed asphalt surface is pre-compacted before rolling over, the task, the continuous upward and downward movement of the tamper strip of the screed loss as possible and with a simple and robust mechanical solution from one of an electric - or hydraulic motor provided to dissipate continuous rotational movement, while a uniform possible load on the drive motor to reach. In addition, it is desirable that the stroke of the tamper bar can be adjusted in order to optimally take into account different installation situations / asphalt thicknesses, it being further advantageous if the bottom dead center remains unchanged during adjustment.

Aus EP 2 325 391 A1 ist eine Einbaubohle bekannt, bei welcher die Stampferleiste von Pleuel angetrieben wird, welche auf einer Exzenterwelle gelagert und durch Rotation der Welle aufwärts- und abwärts bewegt werden. Die Exzentrizität der Exzenter der Exzenterwelle kann durch Drehrichtungsumkehr der Exzenterwelle geändert werden. Diese Einbaubohle weist den Nachteil auf, dass sie eine komplizierte Exzenterwelle aufweist, welche aufwendig in der Herstellung und im Unterhalt ist. Zudem kann bei dieser Einbaubohle der Hub der Stampferleiste nicht stufenlos eingestellt werden, sondern lediglich zwischen zwei Hüben gewählt werden.Out EP 2 325 391 A1 a screed is known in which the tamper bar is driven by connecting rods, which are mounted on an eccentric shaft and moved by rotation of the shaft up and down. The eccentricity of the eccentric of the eccentric shaft can be changed by reversing the direction of rotation of the eccentric shaft. This screed has the disadvantage that it has a complicated eccentric shaft, which is expensive to manufacture and maintain. In addition, in this screed, the stroke of the tamper bar can not be adjusted continuously, but only be chosen between two strokes.

Aus DE 10 2006 046 250 A1 ist eine Einbaubohle bekannt, bei welcher die Stampferleiste über eine Lasche, welche an einem Ende eines schwenkbaren Hebels angelenkt ist, angetrieben wird. Der Hebel wird über einen Kurbelzapfen einer Antriebswelle, welcher in ein Langloch im Hebel eingreift und bei Rotation der Antriebswellen in dem Langloch hin und her läuft, um eine Schwenkachse herum hin und her geschwenkt, wodurch die Lasche und mit dieser die Stampferleiste aufwärts und abwärts geschwenkt wird. Der Hub der Stampferleiste lässt sich durch Veränderung des Abstands zwischen der Rotationsachse der Antriebswelle und der Schwenkachse stufenlos einstellen. Diese Einbaubohle weist den Nachteil auf, dass sie ein kompliziertes Hebelwerk aufweist, welches aufwendig in der Herstellung und im Unterhalt ist, und innerhalb welchem grosse Kräfte auftreten, was zu Verformungen und erhöhtem Verschleiss führen kann. Insbesondere die Hin- und Herbewegung des Kurbelzapfens innerhalb des Langlochs ist verschleissanfällig und kann schnell zu erhöhtem Spiel im Mechanismus führen.Out DE 10 2006 046 250 A1 For example, a screed is known in which the tamper strip is driven by a tab which is hinged to one end of a pivotable lever. The lever is pivoted about a pivot pin of a drive shaft, which engages in a slot in the lever and runs in rotation of the drive shafts in the slot back and forth around a pivot axis around, whereby the tab and with this the tamper bar pivoted upwards and downwards becomes. The stroke of the tamper bar can be adjusted continuously by changing the distance between the axis of rotation of the drive shaft and the pivot axis. This screed has the disadvantage that it has a complicated lever mechanism, which is expensive to manufacture and maintain, and within which large forces occur, which can lead to deformation and increased wear. In particular, the reciprocating motion of the crankpin within the Slotted hole is susceptible to wear and can quickly lead to increased play in the mechanism.

Die zuvor erwähnten Einbaubohlen weisen zudem den Nachteil auf, dass der Antriebsmotor bei jeder Umdrehung einer ausgeprägten Lastspitze ausgesetzt wird, was abträglich für dessen Lebensdauer ist.The screeds mentioned above also have the disadvantage that the drive motor is exposed to a pronounced peak load at each revolution, which is detrimental to its life.

Aus EP 0 374 428 A1 ist eine Einbaubohle mit einer ersten Stampferleiste zur Vorverdichtung und einer zweiten Stampferleiste zur Nachverdichtung bekannt, welche an den freien Enden eines doppelseitigen Hebels befestigt sind, der über ein von einer Exzenterwelle angetriebenes Pleuel um eine Schwenkachse herum hin und her geschwenkt wird und damit eine abwechselnde Aufwärts- und Abwärtsbewegung der beiden Stampferleisten bewirkt. Die Exzentrizität der Exzenterwelle ist einstellbar und damit der Hub der Stampferleisten. Auch wenn bei dieser Einbaubohle der zuletzt genannte Nachteil der zuvor erwähnten Einbaubohlen abgeschwächt wird, da der Antriebsmotor bei jeder Umdrehung zwei Lastspitzen ausgesetzt wird, so weist diese Einbaubohle doch den Nachteil auf, dass zwei hintereinandergeschaltete Stampferleisten schwierig zu bedienen und in vielen Fällen nicht wünschenswert sind, ganz davon abgesehen, dass sie einen sehr aufwändigen und hochspezifischen Aufbau der Einbaubohle erfordern, was weitere Nachteile mit sich bringt.Out EP 0 374 428 A1 is a screed with a first tamper strip for precompression and a second tamping strip for densification are known, which are secured to the free ends of a double-sided lever which is pivoted about a driven by an eccentric shaft connecting rod about a pivot axis around and thus an alternate upward - And downward movement of the two Stampferleisten causes. The eccentricity of the eccentric shaft is adjustable and thus the stroke of the tamper bars. Even if this screed the last-mentioned disadvantage of the aforementioned screeds is weakened, since the drive motor is exposed to two load peaks at each revolution, so this screed but has the disadvantage that two successive tamper bars difficult to use and are not desirable in many cases not to mention that they require a very complex and highly specific construction of the screed, which brings further disadvantages.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Es stellt sich deshalb die Aufgabe, hier eine technische Lösung zur Verfügung zu stellen, welche die zuvor beschriebenen Nachteile des Standes der Technik nicht aufweist oder zumindest teilweise vermeidet.It is therefore the object to provide a technical solution that does not have the disadvantages of the prior art described above or at least partially avoids.

Diese Aufgabe wird durch die Gegenstände der unabhängigen Patentansprüche gelöst.This object is solved by the subject matters of the independent claims.

Gemäss diesen betrifft ein erster Aspekt der Erfindung ein Verfahren zur Umwandlung einer kontinuierlichen rotatorischen Bewegung in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende translatorische Bewegung. Das Verfahren umfasst die Schritte:

  1. a) Erzeugen einer kontinuierlichen Rotationsbewegung eines ersten Bauteils in einer ersten Rotationsrichtung um eine erste Rotationsachse herum;
  2. b) Umwandeln der kontinuierlichen Rotationsbewegung des ersten Bauteils über eine erste Kopplungsanordnung in eine sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung eines zweiten Bauteils um eine zweite Rotationsachse herum; und
  3. c) Umwandeln der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Bauteils über eine zweite Kopplungsanordnung in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung eines dritten Bauteils, derart, dass ein erster der Umkehrpunkte der sich fortlaufend umkehrenden Translationsbewegung des dritten Bauteils jeweils dann erreicht wird, wenn das zweite Bauteil eine bestimmte rotatorische Position zwischen den beiden Umkehrpunkten seiner sich fortlaufend umkehrenden Rotationsbewegung einnimmt.
In accordance with these, a first aspect of the invention relates to a method for converting a continuous rotational motion into a relative one their direction of motion continuously reversing translational movement. The method comprises the steps:
  1. a) generating a continuous rotational movement of a first component in a first rotational direction about a first axis of rotation around;
  2. b) converting the continuous rotational movement of the first component via a first coupling arrangement into a rotational movement of a second component that continuously reverses with respect to its rotational direction about a second axis of rotation; and
  3. c) converting the rotational movement of the second component that continuously reverses with respect to its rotational direction via a second coupling arrangement into a translational movement of a third component that continuously reverses its direction of movement such that a first one of the reversal points of the continuously reversing translational movement of the third component is then achieved when the second component assumes a certain rotational position between the two reversal points of its continuously reversing rotational movement.

Mit anderen Worten wird also eine kontinuierliche Rotationsbewegung eines ersten Bauteils über eine erste Kopplungsanordnung in eine sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung (Hin- und Herschwenkbewegung) eines zweiten Bauteils umgewandelt und diese sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung über eine zweite Kopplungsanordnung in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung eines dritten Bauteils umgewandelt. Dies erfolgt derart, dass ein erster der Umkehrpunkte der sich fortlaufend umkehrenden Translationsbewegung des dritten Bauteils jeweils dann vorliegt, wenn das zweite Bauteil eine bestimmte rotatorische Position zwischen den beiden Umkehrpunkten seiner sich fortlaufend umkehrenden Rotationsbewegung einnimmt. Der zweite Umkehrpunkt der sich fortlaufend umkehrenden Translationsbewegung des dritten Bauteils liegt jeweils dann vor, wenn das zweite Bauteil sich in einem der beiden Umkehrpunkte seiner sich fortlaufend umkehrenden Rotationsbewegung befindet. Auf diese Weise ergibt sich bei jeder vollständigen Umdrehung (360°) des ersten Bauteils eine zweifache Hin- und Herbewegung des dritten Bauteils.In other words, therefore, a continuous rotational movement of a first component is converted via a first coupling arrangement into a rotational movement (reciprocating motion) continuously reversing with respect to its rotational direction of a second component and this rotating rotational direction continuously reversing rotational movement via a second coupling arrangement in a with respect to their direction of movement continuously reversing translational movement of a third component converted. This is done such that a first of the reversal points of the continuously reversing translational movement of the third component is present in each case when the second component occupies a specific rotational position between the two reversal points of its continuously reversing rotational movement. The second turning point of itself continuously reversing translational movement of the third component is in each case when the second component is in one of the two reversal points of its continuously reversing rotational movement. In this way, every two complete revolutions (360 °) of the first component results in a double back and forth movement of the third component.

Durch das erfindungsgemässe Verfahren wird es unter anderem möglich, die fortlaufende Aufwärts- und Abwärtsbewegung der Stampferleiste einer Einbaubohle eines Strassenfertigers relativ verlustarm und mit einer einfachen und robusten mechanischen Lösung aus einer von einem Antriebsmotor bereitgestellten kontinuierlichen Rotationsbewegung abzuleiten, bei einer relativ gleichmässigen Belastung des Antriebsmotors.The method according to the invention makes it possible, inter alia, to derive the continuous upward and downward movement of the tamper strip of a screed of a paver with relatively little loss and with a simple and robust mechanical solution from a continuous rotational movement provided by a drive motor, with a relatively uniform loading of the drive motor.

In einer bevorzugten Ausführungsform des Verfahrens erfolgt das Umwandeln der sich fortlaufend umkehrenden Rotationsbewegung des zweiten Bauteils in die sich fortlaufend umkehrende Translationsbewegung des dritten Bauteils derart, dass der erste Umkehrpunkt der sich fortlaufend umkehrenden Translationsbewegung des dritten Bauteils jeweils dann erreicht wird, wenn das zweiten Bauteil eine genau mittig zwischen den beiden Umkehrpunkten seiner sich fortlaufend umkehrenden Rotationsbewegung liegende rotatorische Position einnimmt. Hierdurch wird erreicht, dass der zweite Umkehrpunkt der fortlaufend umkehrenden Translationsbewegung des dritten Bauteils, welcher jeweils dann vorliegt, wenn das zweiten Bauteil einen der beiden Umkehrpunkte seiner sich fortlaufend umkehrenden Rotationsbewegung einnimmt, immer am gleichen Ort zu liegen kommt, so dass die Amplitude der fortlaufend umkehrenden Translationsbewegung des dritten Bauteils bei jeder Hin- und Herbewegung identisch ist.In a preferred embodiment of the method, the continuously reversing rotational movement of the second component is converted into the consecutively reversing translational movement of the third component such that the first reversal point of the continuously reversing translational movement of the third component is achieved when the second component engages located exactly in the middle between the two reversal points of its continuously reversing rotational movement lying rotational position. This ensures that the second reversal point of the continuously reversing translational movement of the third component, which is present in each case when the second component occupies one of the two reversal points of its continuously reversing rotational movement, always comes to rest at the same location, so that the amplitude of the continuous reversing translational movement of the third component in each reciprocation is identical.

Mit Vorteil wird das Umwandeln der kontinuierlichen Rotationsbewegung des ersten Bauteils in die sich fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils dadurch bewerkstelligt, dass ein erstes Kopplungselement, welches über einen exzentrisch zur ersten Rotationsachse angeordneten Kurbelzapfen mit dem ersten Bauteil und über einen exzentrisch zur zweiten Rotationsachse angeordneten ersten Kopplungszapfen mit dem zweiten Bauteil verbunden ist, durch die kontinuierliche Rotationsbewegung des ersten Bauteils über den Kurbelzapfen in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung versetzt wird und mittels dieser Translationsbewegung über den ersten Kopplungszapfen die sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils bewirkt. Auf diese Weise lässt sich diese Umwandlung durch eine einfache und robuste mechanische Zwangskopplung mit einem hohen mechanischen Wirkungsgrad erreichen.Advantageously, the conversion of the continuous rotational movement of the first component into the continuously reversing rotational movement of the second component is accomplished by a first coupling element, which is connected via an eccentric to the first axis of rotation arranged crank pin with the first component and an eccentric to the second axis of rotation arranged first coupling pin with the second component, offset by the continuous rotational movement of the first member via the crank pin in a direction of movement with respect to continuously reversing translational movement is caused and by means of this translational movement over the first coupling pin which with respect to its rotational direction continuously reversing rotational movement of the second component. In this way, this conversion can be achieved by a simple and robust mechanical positive coupling with a high mechanical efficiency.

Bevorzugterweise wird dabei die Exzentrizität des Kurbelzapfens eingestellt oder so verändert, und zwar bevorzugterweise während der Rotationsbewegung des ersten Bauteils, dass die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des ersten Kopplungselement eine gewünschte Amplitude aufweist. Hierdurch lässt sich Einfluss auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils nehmen und damit auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils.Preferably, the eccentricity of the crank pin is adjusted or changed so, preferably during the rotational movement of the first component, that with respect to their direction of rotation continuously reversing translational movement of the first coupling element has a desired amplitude. As a result, it is possible to influence the amplitude of the rotational movement of the second component, which is continuously reversing with respect to its direction of movement, and thus the amplitude of the translational movement of the third component, which continuously reverses with respect to its direction of movement.

Dies kann beispielsweise durch Drehrichtungsumkehr des ersten Bauteils erfolgen, z.B. derart, dass der Kurbelzapfen durch Drehrichtungsumkehr des ersten Bauteils entlang einer Bahnkurve am ersten Bauteil verschoben wird auf eine Position, welche einen andere Abstand zur Rotationsachse des ersten Bauteils aufweist als seine vorherige Position. Auf diese Weise lässt sich eine Veränderbarkeit der Exzentrizität mit einfachen Mitteln realisieren.This can be done for example by reversing the direction of rotation of the first component, for example, such that the crank pin is shifted by reversing the direction of rotation of the first component along a trajectory on the first component to a position which has a different distance from the axis of rotation of the first component than its previous position. In this way a variability of the eccentricity can be realized with simple means.

Alternativ oder ergänzend ist es dabei auch bevorzugt, dass die Exzentrizität des ersten Kopplungszapfens so eingestellt oder verändert wird, bevorzugterweise während der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Bauteils, dass diese Rotationsbewegung eine gewünschte Amplitude aufweist. Hierdurch lässt sich ebenfalls Einfluss auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils nehmen.Alternatively or additionally, it is also preferred that the eccentricity of the first coupling pin is adjusted or changed, preferably during the rotational movement of the second component that continuously reverses with respect to its rotational direction, that this rotational movement has a desired amplitude. As a result, it is likewise possible to influence the amplitude of the translational movement of the third component that is continuously reversing with regard to its direction of movement.

In noch einer weiteren bevorzugten Ausführungsform des Verfahrens wird das Umwandeln der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Bauteils in die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des dritten Bauteils dadurch bewerkstelligt, dass ein zweites Kopplungselement, welches mit dem dritten Bauteil verbunden ist und über einen exzentrisch zur zweiten Rotationsachse angeordneten zweiten Kopplungszapfen mit dem zweiten Bauteil verbunden ist, durch die sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils über den zweiten Kopplungszapfen in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung versetzt wird und mittels dieser Translationsbewegung die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des dritten Bauteils bewirkt. Auf diese Weise lässt sich diese Umwandlung durch eine einfache und robuste mechanische Zwangskopplung mit einem hohen mechanischen Wirkungsgrad erreichen.In yet another preferred embodiment of the method, the conversion of the rotational movement of the second component, which is continuously reversing with respect to its rotational direction, into the translational movement of the third component that continuously reverses with respect to its direction of movement is accomplished by a second coupling element, which is connected to the third component and is arranged connected via an eccentric to the second axis of rotation arranged second coupling pin with the second component, is offset with respect to its rotational direction continuously reversing rotational movement of the second component via the second coupling pin in a direction of movement with respect to constantly reversing translational movement and by means of this translational movement with respect to their direction of movement continuously reversing translational movement of the third component causes. In this way, this conversion can be achieved by a simple and robust mechanical positive coupling with a high mechanical efficiency.

Bevorzugterweise wird die Exzentrizität des zweiten Kopplungszapfens so eingestellt bzw. verändert, bevorzugterweise während der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Elements, dass die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des zweiten Kopplungselement eine gewünschte Amplitude aufweist. Hierdurch lässt sich ebenfalls Einfluss auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils nehmen.Preferably, the eccentricity of the second coupling pin is adjusted or changed, preferably during the rotational movement of the second element that continuously reverses with respect to its direction of rotation, that the translational movement that continuously reverses with respect to its direction of movement of the second coupling element has a desired amplitude. As a result, it is likewise possible to influence the amplitude of the translational movement of the third component which is continuously reversing with regard to its direction of movement.

Dabei ist es weiter bevorzugt, dass die Längsachsen des ersten und des zweiten Kopplungszapfens zusammenfallen. Insbesondere für den Fall, dass der erste Kopplungszapfen und der zweite Kopplungszapfen dabei von einem gemeinsamen Kopplungszapfen gebildet sind, ergibt sich der Vorteil, dass ein besonders einfacher Aufbau möglich wird.It is further preferred that the longitudinal axes of the first and the second coupling pin coincide. In particular, for the case that the first coupling pin and the second coupling pin are formed by a common coupling pin, there is the advantage that a particularly simple structure is possible.

Alternativ ist es bevorzugt, dass die Längsachsen des ersten und des zweiten Kopplungszapfens nicht zusammenfallen. Auf diese Weise können sie unterschiedliche Exzentrizitäten aufweisen und gegebenenfalls bezüglich ihrer Exzentrizität unabhängig voneinander eingestellt bzw. verändert werden.Alternatively, it is preferable that the longitudinal axes of the first and second coupling pins do not coincide. In this way, they can have different eccentricities and optionally set or changed independently of one another with respect to their eccentricity.

Ist das zweite Kopplungselement starr mit dem dritten Bauteil verbunden, was bevorzugt ist, so ergibt sich eine besonders einfache und verlustfreie Kopplung zwischen diesen Komponenten.If the second coupling element is rigidly connected to the third component, which is preferred, the result is a particularly simple and lossless coupling between these components.

Ein zweiter Aspekt der Erfindung betrifft die Anwendung des Verfahrens gemäss dem ersten Aspekt der Erfindung zur Erzeugung einer fortlaufenden Aufwärts- und Abwärtsbewegung der Stampferleiste einer Einbaubohle eines Strassenfertigers, und zwar bevorzugterweise während der Erstellung einer Asphaltdecke. Bei derartigen Anwendungen kommen die Vorteile der Erfindung besonders deutlich zum Tragen.A second aspect of the invention relates to the use of the method according to the first aspect of the invention for producing a continuous upward and downward movement of the tamping strip of a screed of a paver, preferably during the preparation of an asphalt surface. In such applications, the advantages of the invention are particularly evident.

Dabei ist es bei dieser Anwendung weiter bevorzugt, dass die Exzentrizität des Kurbelzapfens, die Exzentrizität des ersten Kopplungszapfens und/oder die Exzentrizität des zweiten Kopplungszapfens eingestellt bzw. verändert wird oder werden, zur Einstellung des Hubs der Stampferleiste, insbesondere derart, dass dessen unterer Totpunkt unverändert bleibt und dessen oberer Totpunkt eingestellt bzw. verändert wird. Auf diese Weise lässt sich der Hub der Stampferleiste auf verschieden dicke Asphaltdecken einstellen.It is further preferred in this application that the eccentricity of the crank pin, the eccentricity of the first coupling pin and / or the eccentricity of the second coupling pin is set or changed or to adjust the stroke of the tamper strip, in particular such that its bottom dead center remains unchanged and its top dead center is set or changed. In this way, the stroke of the tamper bar can be adjusted to different thickness asphalt pavements.

Ein dritter Aspekt der Erfindung betrifft eine Vorrichtung zur Durchführung des Verfahrens gemäss dem ersten Aspekt der Erfindung. Die Vorrichtung umfasst ein erstes Bauteil, welches derartig gelagert ist, dass es eine kontinuierliche Rotationsbewegung in einer ersten Rotationsrichtung um eine erste Rotationsachse herum vollführen kann, ein zweites Bauteil, welches derartig gelagert ist, dass es eine sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung um eine zweite Rotationsachse herum vollführen kann und ein drittes Bauteil, welches derartig gelagert ist, dass es eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung vollführen kann.A third aspect of the invention relates to an apparatus for carrying out the method according to the first aspect of the invention. The device comprises a first component, which is mounted such that it can perform a continuous rotational movement in a first rotational direction about a first axis of rotation, a second component, which is mounted such that there is a with respect to their rotational direction continuously reversing rotational movement about a second rotational axis can perform around and a third component, which is mounted such that it can perform a with respect to their direction of rotation continuously reversing translational movement.

Das erste Bauteil und das zweite Bauteil sind mittels einer ersten Kopplungsanordnung mechanisch derartig miteinander gekoppelt, dass eine kontinuierliche Rotationsbewegung des ersten Bauteils in der ersten Rotationsrichtung um die erste Rotationsachse herum eine sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils um die zweite Rotationsachse herum bewirkt.The first component and the second component are mechanically coupled to one another by means of a first coupling arrangement in such a way that a continuous rotational movement of the first component in the first rotational direction about the first rotational axis causes a rotational movement of the second component continuously reversing with respect to its rotational direction about the second rotational axis ,

Das zweite Bauteil und das dritte Bauteil sind mittels einer zweiten Kopplungsanordnung mechanisch derartig miteinander gekoppelt, dass die sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des dritten Bauteils bewirkt, und zwar derart, dass ein erster der Umkehrpunkte der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils jeweils dann vorliegt, wenn das zweite Bauteil eine bestimmte rotatorische Position zwischen den beiden Umkehrpunkten seiner sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung einnimmt.The second component and the third component are mechanically coupled to one another by means of a second coupling arrangement in such a way that the rotational movement of the second component with respect to its rotational direction causes a translational movement of the third component that continuously reverses with respect to its direction of movement Inversion points of the translational movement of the third component, which continuously reverses with regard to its direction of movement, are present in each case when the second component has a specific rotational position between the two reversal points of its relative points its rotational direction continuously reversing rotational movement occupies.

Mit der erfindungsgemässen Vorrichtung ist es unter anderem möglich, die fortlaufende Aufwärts- und Abwärtsbewegung der Stampferleiste einer Einbaubohle eines Strassenfertigers relativ verlustarm und mit einer einfachen und robusten mechanischen Lösung aus einer von einem Antriebsmotor bereitgestellten kontinuierlichen Rotationsbewegung abzuleiten, bei einer relativ gleichmässigen Belastung des Antriebsmotors.With the device according to the invention it is possible, inter alia, to derive the continuous upward and downward movement of the tamper strip of a screed of a road paver with relatively little loss and with a simple and robust mechanical solution from a continuous rotational movement provided by a drive motor, with a relatively uniform loading of the drive motor.

Mit Vorteil ist dabei die zweite Kopplungsanordnung derartig ausgebildet, dass der erste Umkehrpunkt der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils jeweils dann erreicht wird, wenn das zweite Bauteil eine exakt mittig zwischen den beiden Umkehrpunkten seiner sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung liegende rotatorische Position einnimmt. Hierdurch wird erreicht, dass der zweite Umkehrpunkt der sich fortlaufend umkehrenden Translationsbewegung des dritten Bauteils, welcher jeweils dann erreicht ist, wenn das zweiten Bauteil einen der beiden Umkehrpunkte seiner sich fortlaufend umkehrenden Rotationsbewegung erreicht, immer am gleichen Ort zu liegen kommt, so dass die Amplituden der beiden Translationsbewegungen des dritten Bauteils, welches dieses während einer Umdrehung (360°) des ersten Bauteils vollführt, identisch sind.Advantageously, the second coupling arrangement is designed in such a way that the first reversal point of the translational motion of the third component, which is continuously reversing with respect to its direction of motion, is achieved when the second component has a rotational movement that is exactly centered between the two reversal points of its rotational direction rotatory position occupies. This ensures that the second reversal point of the continuously reversing translational movement of the third component, which is achieved in each case when the second component reaches one of the two reversal points of its continuously reversing rotational movement, always comes to rest at the same location, so that the amplitudes the two translational movements of the third component, which performs this during one revolution (360 °) of the first component, are identical.

In einer bevorzugten Ausführungsform der Vorrichtung umfasst die erste Kopplungsanordnung ein erstes Kopplungselement, welches über einen exzentrisch zur ersten Rotationsachse angeordneten Kurbelzapfen mit dem ersten Bauteil und über einen exzentrisch zur zweiten Rotationsachse angeordneten ersten Kopplungszapfen mit dem zweiten Bauteil verbunden ist, derart, dass das erste Kopplungselement durch die kontinuierliche Rotationsbewegung des ersten Bauteils über den Kurbelzapfen in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung versetzt wird und durch diese Translationsbewegung über den ersten Kopplungszapfen die sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils bewirkt. Auf diese Weise lässt sich das Umwandeln der kontinuierlichen Rotationsbewegung des ersten Bauteils in die sich fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils durch eine einfache und robuste mechanische Zwangskopplung mit einem hohen mechanischen Wirkungsgrad erreichen.In a preferred embodiment of the device, the first coupling arrangement comprises a first coupling element, which is connected to the first component via a crank pin arranged eccentrically to the first rotation axis and to the second component via a first coupling pin arranged eccentrically to the second rotation axis, such that the first coupling element by the continuous rotational movement of the first component via the crank pin into a With respect to their direction of movement continuously reversing translational movement is offset and causes by this translational movement over the first coupling pin which with respect to their rotational direction continuously reversing rotational movement of the second component. In this way, the conversion of the continuous rotational movement of the first component into the continuously reversing rotational movement of the second component can be achieved by a simple and robust mechanical positive coupling with a high mechanical efficiency.

Bevorzugterweise ist dabei die Exzentrizität des Kurbelzapfens einstellbar oder veränderbar, und zwar bevorzugterweise während der Rotationsbewegung des ersten Bauteils in der ersten Rotationsrichtung, so dass die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des ersten Kopplungselement bezüglich ihrer Amplitude einstellbar bzw. veränderbar ist. Hierdurch lässt sich Einfluss auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils nehmen und damit auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils.Preferably, the eccentricity of the crank pin is adjustable or changeable, preferably during the rotational movement of the first component in the first rotational direction, so that with respect to their direction of rotation continuously reversing translational movement of the first coupling element is adjustable or variable with respect to their amplitude. As a result, it is possible to influence the amplitude of the rotational movement of the second component, which is continuously reversing with respect to its direction of movement, and thus the amplitude of the translational movement of the third component, which continuously reverses with respect to its direction of movement.

In einer bevorzugten Ausführungsform kann dies durch Drehrichtungsumkehr des ersten Bauteils erfolgen, z.B. derart, dass der Kurbelzapfen durch Drehrichtungsumkehr des ersten Bauteils entlang einer Bahnkurve am ersten Bauteil auf eine Position verschoben wird, welche einen anderen Abstand zur Rotationsachse des ersten Bauteils aufweist als seine vorherige Position. Auf diese Weise lässt sich eine Einstellbarkeit bzw. Veränderbarkeit der Exzentrizität mit einfachen Mitteln realisieren.In a preferred embodiment, this can be done by reversing the direction of rotation of the first component, e.g. such that the crank pin is displaced by reversing the direction of rotation of the first component along a trajectory on the first component to a position which is at a different distance from the axis of rotation of the first component than its previous position. In this way, an adjustability or variability of the eccentricity can be realized with simple means.

Alternativ oder ergänzend ist es dabei auch bevorzugt, dass die Exzentrizität des ersten Kopplungszapfens einstellbar oder veränderbar ist, bevorzugterweise während der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Bauteils, so dass sich die bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils in ihrer Amplitude einstellen bzw. verändern lässt. Hierdurch lässt sich ebenfalls Einfluss auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils nehmen.Alternatively or additionally, it is also preferred that the eccentricity of the first coupling pin is adjustable or variable, preferably during the rotation direction continuously reversing rotational movement of the second component, so that can be set or change in their amplitude with respect to their direction of rotation continuously reversing rotational movement of the second component in its amplitude. As a result, it is likewise possible to influence the amplitude of the translational movement of the third component which is continuously reversing with regard to its direction of movement.

In einer weiteren bevorzugten Ausführungsform der Vorrichtung umfasst die zweite Kopplungsanordnung ein zweites Kopplungselement, welches mit dem dritten Bauteil verbunden ist und über einen exzentrisch zur zweiten Rotationsachse angeordneten zweiten Kopplungszapfen mit dem zweiten Bauteil verbunden ist, derart, dass das zweite Kopplungselement durch die sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung des zweiten Bauteils über den zweiten Kopplungszapfen in eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung versetzt wird und durch diese Translationsbewegung die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des dritten Bauteils bewirkt. Auf diese Weise lässt sich das Umwandeln der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Bauteils in die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des dritten Bauteils durch eine einfache und robuste mechanische Zwangskopplung mit einem hohen mechanischen Wirkungsgrad erreichen.In a further preferred embodiment of the device, the second coupling arrangement comprises a second coupling element, which is connected to the third component and is connected to the second component via a second coupling pin arranged eccentrically to the second rotation axis, such that the second coupling element is characterized by the second coupling element Rotation direction continuously reversing rotational movement of the second component is offset via the second coupling pin in a translational motion with respect to their direction of successively reversing translational movement and by means of this translational movement which causes with respect to their direction of movement continuously reversing translational movement of the third component. In this way, the conversion of the rotational movement of the second component which continuously reverses with respect to its rotational direction into the translational movement of the third component that continuously reverses with respect to its direction of movement can be achieved by a simple and robust mechanical positive coupling with a high mechanical efficiency.

Bevorzugterweise ist die Exzentrizität des zweiten Kopplungszapfens einstellbar oder veränderbar, bevorzugterweise während der sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung des zweiten Elements, so dass die sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung des zweiten Kopplungselement bezüglich ihrer Amplitude einstellbar bzw. veränderbar ist. Hierdurch lässt sich ebenfalls Einfluss auf die Amplitude der sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrenden Translationsbewegung des dritten Bauteils nehmen.Preferably, the eccentricity of the second coupling pin is adjustable or changeable, preferably during the rotation direction continuously reversing rotational movement of the second element, so that with respect to their direction of rotation continuously reversing translational movement of the second coupling element is adjustable or variable with respect to their amplitude. This leaves also influence the amplitude of the translational motion of the third component that is continuously reversing with respect to its direction of movement.

Dabei ist es weiter bevorzugt, dass die Längsachsen des ersten und des zweiten Kopplungszapfens zusammenfallen. Insbesondere für den Fall, dass der erste Kopplungszapfen und der zweite Kopplungszapfen dabei von einem gemeinsamen Kopplungszapfen gebildet sind, ergibt sich ein besonders einfacher Aufbau.It is further preferred that the longitudinal axes of the first and the second coupling pin coincide. In particular, for the case that the first coupling pin and the second coupling pin are formed by a common coupling pin, there is a particularly simple structure.

Alternativ ist es dabei bevorzugt, dass die Längsachsen des ersten und des zweiten Kopplungszapfens nicht zusammenfallen. Auf diese Weise können sie unterschiedliche Exzentrizitäten aufweisen bzw. gegebenenfalls bezüglich ihrer Exzentrizität unabhängig voneinander eingestellt oder verändert werden.Alternatively, it is preferred that the longitudinal axes of the first and the second coupling pin do not coincide. In this way, they can have different eccentricities or optionally adjusted or changed independently of one another with respect to their eccentricity.

Ist das zweite Kopplungselement starr mit dem dritten Bauteil verbunden, was bevorzugt ist, so ergibt sich eine besonders einfache und verlustfreie Kopplung zwischen diesen Komponenten.If the second coupling element is rigidly connected to the third component, which is preferred, the result is a particularly simple and lossless coupling between these components.

WEGE ZUR AUSFÜHRUNG DER ERFINDUNGWAYS FOR CARRYING OUT THE INVENTION

Fig. 1 zeigt eine stark vereinfachte Darstellung einer ersten erfindungsgemässen Vorrichtung zur Erzeugung der fortlaufenden Aufwärts- und Abwärtsbewegung der Stampferleiste 4 der Einbaubohle eines Strassenfertigers. Fig. 1 shows a greatly simplified representation of a first inventive device for generating the continuous upward and downward movement of the tamper strip 4 of the screed of a paver.

Wie zu erkennen ist, weist die Vorrichtung eine kreisrunde Kurbelscheibe 1 (anspruchsgemässes erstes Bauteil) mit einem Kurbelzapfen 6 auf, welche im bestimmungsgemässen Betrieb von einem Motor (nicht dargestellt) in Rotation versetzt wird, derart, dass sie eine kontinuierliche Rotationsbewegung R1 im Uhrzeigersinn (anspruchsgemässe erste Rotationsrichtung) um eine durch ihr Zentrum verlaufende Rotationsachse X1 (anspruchsgemässe erste Rotationsachse) herum vollführt.As can be seen, the apparatus comprises a circular crank disk 1 (first component according to the claims) with a crank pin 6 which is set in rotation during normal operation by a motor (not shown) in such a way that it drives a continuous clockwise rotation R1 (FIG. Claimed first rotational direction) around a running through its center axis of rotation X1 (claim the first axis of rotation) performs around.

Über den Kurbelzapfen 6, welcher exzentrisch zur Rotationsachse X1 an der Kurbelscheibe 1 angeordnet ist, ist ein erstes Ende einer ersten Kopplungsstange 2 (anspruchsgemässes erstes Kopplungselement) an der Kurbelscheibe 1 angelenkt, deren zweites Ende über einen ersten Kopplungszapfen 8 an einer kreisrunden Pendelscheibe 3 (anspruchsgemässes zweites Bauteil), welche schwenkbar um eine durch ihr Zentrum verlaufende Rotationsachse X2 (anspruchsgemäss zweite Rotationsachse) gelagert ist, angelenkt ist, derart, dass die kontinuierliche Rotationsbewegung R1 der Kurbelscheibe 1 eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung T2 der ersten Kopplungsstange 2 bewirkt und diese Translationsbewegung T2 der ersten Kopplungsstange 2 wiederum eine sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung R2 der Pendelscheibe 3 um ihre Rotationsachse X2 herum bewirkt, also ein Hin- und Herschwenken R2 der Pendelscheibe 3 um ihre Rotationsachse X2 herum. Hierzu ist der Kopplungszapfen 8 exzentrisch zur Rotationsachse X2 an der Pendelscheibe 3 angeordnet.Via the crank pin 6, which is arranged eccentrically to the rotation axis X1 on the crank disc 1, a first end of a first coupling rod 2 (claims first coupling element) is hinged to the crank disc 1, the second end via a first coupling pin 8 on a circular pendulum disc 3 (Fig. Anspruchgemässes second component), which is pivotally mounted about an axis of rotation extending through its center X2 (according to the second axis of rotation) is articulated, such that the continuous Rotation movement R1 of the crank disk 1 causes a translational movement T2 of the first coupling rod 2 which is continuously reversing with respect to its direction of movement and this translational movement T2 of the first coupling rod 2 in turn causes a rotational movement R2 of the pendulum disc 3 about its axis of rotation X2, ie an outward rotation, with respect to its rotational direction and pivoting R2 of the pendulum disk 3 around its axis of rotation X2. For this purpose, the coupling pin 8 is arranged eccentrically to the rotation axis X2 on the pendulum disc 3.

Ebenfalls exzentrisch zur Rotationsachse X2 angeordnet an der Pendelscheibe 3 ist ein zweiter Kopplungszapfen 5, über welchen ein erstes Ende einer zweiten Kopplungsstange 9 (anspruchsgemässes zweites Kopplungselement) an der Pendelscheibe 3 angelenkt ist, deren zweites Ende starr mit der in einer Führungsanordnung 7 vertikal verschiebbar geführten Stampferleiste 4 (anspruchsgemässes drittes Bauteil) der Einbaubohle verbunden ist, und zwar derart, dass die sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrende Rotationsbewegung R2 der Pendelscheibe 3 eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung T3 der zweiten Kopplungsstange 9 und über diese eine sich bezüglich ihrer Bewegungsrichtung fortlaufend umkehrende Translationsbewegung T1 der Stampferleiste 4 in vertikaler Richtung bewirkt, also eine fortlaufende Aufwärts- und Abwärtsbewegung T1 der Stamperleiste 4. Dabei ist der untere Totpunkt (unterer Umkehrpunkt) der fortlaufenden Aufwärts- und Abwärtsbewegung T1 jeweils dann erreicht, wenn die Pendelscheibe 3 eine rotatorische Position einnimmt, welche in der Mitte zwischen den beiden Umkehrpunkten ihrer sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung R2 liegt. Der obere Totpunkt (oberer Umkehrpunkt) der fortlaufenden Aufwärts- und Abwärtsbewegung T1 der Stampferleiste 4 ist jeweils dann erreicht, wenn sich die Pendelscheibe 3 in einem der beiden Umkehrpunkte ihrer sich bezüglich ihrer Rotationsrichtung fortlaufend umkehrenden Rotationsbewegung R2 befindet.Also arranged eccentrically to the rotation axis X2 on the pendulum disk 3 is a second coupling pin 5, via which a first end of a second coupling rod 9 (claims second coupling element) is hinged to the pendulum disc 3, the second end rigidly guided in a guide assembly 7 vertically displaceable Ramming bar 4 (claims third component) of the screed is connected, in such a way that with respect to their rotational direction continuously reversing rotational movement R2 of the pendulum disc 3 with respect to their direction of successively reversing translational movement T3 of the second coupling rod 9 and on this one with respect to their direction of movement continuously reversing translational movement T1 of the tamper strip 4 in the vertical direction causes, ie a continuous upward and downward movement T1 of the stamper strip 4. Here, the bottom dead center (lower reversal point) is the continuous n upward and downward movement T1 respectively achieved when the pendulum disc 3 assumes a rotational position, which lies in the middle between the two reversal points of their rotational direction with respect to their rotational direction continuously reversing R2. The top dead center (upper reversal point) of the continuous upward and downward movement T1 of the tamper strip 4 is in each case achieved when the pendulum disc 3 is located in one of the two reversal points of their rotational direction R2, which is continuously reversing with respect to their direction of rotation.

Die Exzentrizitäten des Kurbelzapfens 6 und/- oder des ersten Schwenkzapfens 8 sind einstellbar bzw. veränderbar, um eine Einstellung bzw. Veränderung des Hubes der Stampferleiste 4 ohne eine Veränderung des unteren Totpunktes zu ermöglichen.The eccentricities of the crank pin 6 and / or the first pivot pin 8 are adjustable or variable to allow adjustment or change in the stroke of the tamper strip 4 without a change in the bottom dead center.

Fig. 2 zeigt eine stark vereinfachte Darstellung einer zweiten erfindungsgemässen Vorrichtung zur Erzeugung der fortlaufenden Aufwärts- und Abwärtsbewegung der Stampferleiste 4 der Einbaubohle eines Strassenfertigers, welche sich von der in Fig. 1 dargestellten lediglich dadurch unterscheidet, dass das zweite Ende der ersten Kopplungsstange 2 und das erste Ende der zweiten Kopplungsstange 9 über einen gemeinsamen Kopplungszapfen 5, 8 an der Pendelscheibe 3 angelenkt sind. Um eine Einstellung bzw. Veränderung des Hubes der Stampferleiste 4 ohne eine Veränderung des unteren Totpunktes zu ermöglichen, ist hier die Exzentrizität des Kurbelzapfens 6 einstellbar bzw. veränderbar.
