Description

1. Grundlagen1. Basics

Materialien ( z.B. Aufschüttungen, Böden, Fundamente, Frischbeton) können durch Wechselkräfte, die über vibrierende Massen eingeleitet werden, verdichtet werden.Materials (e.g. fillings, floors, foundations, fresh concrete) can by alternating forces that vibrate over masses be initiated, condensed.

Wie gut die Wirkung der eingeleiteten Kräfte im Hinblick auf die Verdichtung ist, hängt davon ab, wie gut Frequenz und Hub der "vibrierenden Wirkmasse" auf den Zustand (physikalische Eigenschaften) der zu verdichtenden Masse abgestimmt sind.How good the effect of the forces introduced in terms of on the compression depends on how good frequency and stroke of the "vibrating active mass" on the state (physical properties) of the mass to be compressed are coordinated.

Nachdem sich typischerweise der Zustand (d.h. die physikalischen Eigenschaften wie Dichte, Elastizität usw.) der zu verdichtenden Materialien während der Bearbeitung ändert, ist eine optimale Wirkung des Verdichtungsgerätes während der gesamten Bearbeitung nur dann zu erreichen, wenn eine entsprechende Anpassung der Arbeitsweise des Gerätes an den Zustand des zu bearbeitenden Materials während der Bearbeitungszeit stattfindet. After the state (i.e. the physical Properties such as density, elasticity etc.) of the to be compacted Changing materials during machining is an optimal one Effect of the compactor during the entire processing can only be achieved if a corresponding adjustment of the Operation of the device to the state of the to be processed Material takes place during the processing time.  

Sind die jeweilige Betriebsart (Frequenz, Hub, Exzenter, Kräfte) und die nötigen physikalischen Eigenschaften des Gerätes bekannt, so können über eine Messung des Verhaltens (Antwort) des Gerätes auf oder in dem zu verdichtenden Material indirekt über Formeln und Kennlinien (Material-Typ) die aktuellen physikalischen Eigenschaften des bearbeiteten Materials errechnet werden.Are the respective operating mode (frequency, stroke, eccentric, forces) and the necessary physical properties of the device known, so by measuring the behavior (answer) of the device on or in the material to be compacted indirectly the current ones via formulas and characteristic curves (material type) physical properties of the processed material can be calculated.

Dies öffnet die Möglichkeit, einer Anpassung der Arbeitsweise des Verdichtungsgeräts an den jeweiligen Zustand des zu verdichtenden Materials, ohne Messungen in dem zu bearbeiteten Material vornehmen zu müssen. This opens up the possibility of adapting the way of working of the compactor to the respective state of the compacting material, without measurements in the processed Need to make material.  

2. Stand der Technik2. State of the art

Heute werden im Allgemeinen verschiedene Vibrations-Gerätetypen zur Verdichtung unterschiedlicher Materialien angeboten.Today there are generally different types of vibration devices offered to compact different materials.

Das heißt, die Geräte sind auf jeweils eine durchschnittliche Eigenschaft der zu bearbeitenden Materialien eingestellt. An manchen hochentwickelten Geräten läßt sich von Hand die Einstellung von Frequenz und Hub verändern.That said, the devices are average on each Property of the materials to be processed set. On some sophisticated devices, the Change the setting of frequency and stroke.

Eine Messung der erreichten Verdichtung wird im bearbeiteten Material gemessen. A measurement of the compression achieved is being processed Material measured.  

3. Beschreibung der Erfindung3. Description of the invention

Die Erfindung hat das Ziel durch Ausnutzung physikalischer Zusammenhänge und die Anwendung modernster Technologie neue Geräteeigenschaften zu erreichen - hier für Vibrations-Verdichtungs-Geräte.The invention has the goal of exploiting physical Connections and the use of the latest technology to achieve new device properties - here for Vibration compaction equipment.

Die Erfindung bezieht sich auf eine Vorrichtung zur automatischen Anpassung der Arbeitsweise von Vibratoren zur Materialverdichtung an den jeweiligen Zustand des zu verdichtenden Materials.The invention relates to a device for automatic adjustment of the way vibrators work Material compaction to the respective state of the to be compacted Materials.

Die Vorrichtung besteht aus einer Kombination von Sensoren, Mikroprozessor und Effectoren, die im Gerätesystem eingebaut sind.The device consists of a combination of sensors, Microprocessor and effectors built into the device system.

Die Sensoren liefern:The sensors deliver:

  • a) den Betriebszustand des Gerätes (Drehzahl, Hub etc.)a) the operating state of the device (Speed, stroke etc.)
  • b) die dynamische Antwort der Bearbeitungsfläche im Kontakt mit dem zu bearbeitenden Material.b) the dynamic response of the processing area in the Contact with the material to be processed.

Der Mikroprozessor wird vor dem Einbau mit den physikalischen Kenndaten des Gerätes, den nötigen Formeln und den Kennlinien der verschiedenen Materialtypen programmiert, er ist dann in der Lage aus dem Materialtyp, dem Betriebszustand des Gerätes und dem dynamischen Antwort-Signal den Zustand (Dichte, Elastizität) des Materials zu errechnen.The microprocessor is connected to the physical one before installation Characteristic data of the device, the necessary formulas and the characteristic curves of the different material types programmed, it is then in the location from the material type, the operating state of the device and the dynamic response signal the state (density, elasticity) to calculate the material.

Über die Effectoren ist dann eine Anpassung der Arbeitsweise (Frequenz, Hub, etc.) des Gerätes möglich mit dem Ziel optimaler Wirkungseinleitung in das Material.The effector is then an adjustment of the working method (Frequency, stroke, etc.) of the device possible with the goal more optimal Initiation of effects into the material.

Über eine "Glättungseinrichtung" werden sprunghafte Änderungen vermieden. Abrupt changes are made via a "smoothing device" avoided.  

Durch diese ständige Anpassung der Arbeitsweise an die sich ändernden Eigenschaften des Materials, wird eine optimale Verdichtung in der kürzest möglichen Zeit erreicht.By constantly adapting the way of working to yourself changing properties of the material will be optimal Compression achieved in the shortest possible time.

Der bearbeitete Materialtyp ist am Gerät einzustellen, wenn das Gerät für mehrere Materialtypen einsetzbar ist.The processed material type must be set on the device if that Device can be used for several types of material.

Zusätzlich können an der Vorrichtung folgende Funktionen bereitgestellt werden:In addition, the following functions can be performed on the device to be provided:

  • - Vorwahl eines bestimmten Verdichtungsgrades (Anzeige wenn erreicht)- Preselection of a certain degree of compaction (Display when reached)
  • - Abruf/Anzeige des erreichten Verdichtungsgrades- Call / display of the degree of compaction achieved
  • - Eingabe neuer Materialkenndaten (Tastatur, PROM-Stecker)- Enter new material data (Keyboard, PROM connector)
