Abstract
Description
Die Erfindung bezieht sich auf einen Schwingungserzeuger für insbesondere Rüttelstationen von beispielsweise Steinformmaschinen mit zumindest einem von einem motorischen Antrieb in Rotationsbewegung versetzbaren, eine innere Unwuchtmasse sowie eine äußere Unwuchtmasse umfassenden Unwuchtkörper, wobei zur stufenlosen Unwuchtverstellung die innere Unwuchtmasse und die äußere Unwuchtmasse relativ zueinander verdrehbar sind.The invention relates to a vibration generator for in particular vibrating stations of, for example, stone molding machines with at least one of a motor Drive that can be rotated, an inner unbalanced mass and an unbalanced mass comprising an outer unbalanced mass, whereby the stepless unbalance adjustment inner unbalanced mass and the outer unbalanced mass relative are rotatable to each other.
Bekannte Schwingungserzeuger für Rüttelstationen von Steinformmaschinen haben zwei benachbart angeordnete, einem Rütteltisch zugeordnete Unwuchtkörper mit insgesamt vier Unwuchtmassen (zwei innere sowie zwei äußere Unwuchtmassen). Die vier Unwuchtmassen sind separat gelagert und über vier Drehstrommotoren, die hinsichtlich ihrer Rotationsgeschwindigkeit elektronisch gesteuert und darüber gekoppelt sind, angetrieben. Zur relativen Verstellung einer inneren Unwuchtmasse gegenüber einer äußeren Unwuchtmasse werden steilgängige Spindeln eingesetzt, um eine stufenlose Unwuchtverstellung und damit eine Amplitudenänderung der erzeugten gerichteten Schwingungen vornehmen zu können.Known vibration generator for vibrating stations from Stone molding machines have two adjacent, a total of one unbalance body assigned to a vibrating table four unbalanced masses (two inner and two outer unbalanced masses). The four unbalanced masses are stored separately and via four three-phase motors, with regard to their Rotation speed electronically controlled and coupled over it. For relative adjustment an inner unbalance mass against one steep unbalanced spindles are used, a stepless unbalance adjustment and so an amplitude change of the generated directional To be able to make vibrations.
Der mit einem solchen Schwingungserzeuger einhergehende baulich und konstruktive Aufwand ist erheblich und beeinflußt die Gesamtkosten einer Steinformmaschine- bzw. -anlage erheblich. Die insgesamt notwendigen Teile, insbesondere auch das Erfordernis von vier separaten Antriebseinheiten, beeinflußt den Platzbedarf eines solchen Schwingungserzeugers nachhaltig. Das wirkt sich auch negativ auf die Gesamtabmessungen einer fertigen Steinformmaschine aus.The one associated with such a vibrator structural and constructive effort is significant and influenced the total cost of a stone molding machine or system considerably. The total necessary parts, in particular also the requirement of four separate drive units, affects the space requirement of such Vibration generator sustainable. That also has an effect negative on the overall dimensions of a finished stone molding machine out.
Es ist Aufgabe der vorliegenden Erfindung, einen Schwingungserzeuger der eingangs genannten Art zu schaffen, mit dem die Unwuchtverstellung sicher und exakt durchzuführen ist, der jedoch insgesamt weniger aufwendig baut und einen geringeren Platzbedarf hat.It is an object of the present invention to Vibration generator of the type mentioned at the beginning create with which the unbalance adjustment safely and precisely is to be carried out, but overall less expensive builds and takes up less space.
Zur Lösung dieser Aufgabe zeichnet sich der Schwingungserzeuger der eingangs genannten Art dadurch aus, daß die innere Unwuchtmasse und die äußere Unwuchtmasse jeweils über einen von einer motorischen Zentralantriebseinheit in Antriebsbewegungen versetzbaren Endlosantriebskörper antreibbar sind und zumindest einem Endlosantriebskörper ein Verstellorgan zugeordnet ist, der diesem Endlosantriebskörper zur relativen Verdrehung der inneren Unwuchtmasse und/oder der äußeren Unwuchtmasse eine seiner Antriebsbewegung überlagerte Zusatzbewegung erteilt.The vibration generator excels in solving this task of the type mentioned in that the inner unbalanced mass and the outer unbalanced mass each via one of a motorized central drive unit in Drive movements of displaceable endless drive bodies can be driven are and at least one endless drive body Adjusting member is assigned to this endless drive body for the relative rotation of the inner unbalance mass and / or the outer unbalanced mass of one of its drive movements overlaid additional movement granted.
Bei dem Schwingungserzeuger nach der Erfindung ist nur noch eine motorische Zentralantriebseinheit notwendig, die die Endlosantriebskörper, vorzugsweise Zahnriemen, der inneren und äußeren Unwuchtmasse antreibt. Dazu hat zweckmäßigerweise die motorische Zentralantriebseinheit zwei Ausgänge mit Antriebszahnrädern, so daß die Endlosantriebskörper ohne das Erfordernis aufwendiger elektronischer Steuerungsmittel mit exakt übereinstimmender Geschwindigkeit anzutreiben sind. Über die Endlosantriebskörper der inneren und der äußeren Unwuchtmasse läßt sich die Unwuchtverstellung durchführen, indem durch die Zusatzbewegung eines Endlosantriebskörper bzw. durch gegensinnige Zusatzbewegungen von beiden Endlosantriebskörpern die ansonsten gleichsinnig und mit übereinstimmender Geschwindigkeit rotierenden innere Unwuchtmasse und äußeren Unwuchtmasse relativ zueinander verdreht werden. Die insgesamt erforderlichen Teile unter Einschluß der Antriebsmittel sind gegenüber herkömmlichen Schwingungserzeugern wesentlich reduziert, womit die Gesamtgestehungskosten des Schwingungserzeugers und damit auch einer mit einem solchen Schwingungserzeuger ausgerüsteten Steinformmaschine erheblich reduziert sind. Gleichwohl arbeitet der Schwingungserzeuger außerordentlich zuverlässig und ist insbesondere in einer Ausbildung, bei der sowohl die innere als auch die äußere Unwuchtmasse eine Zusatzdrehbewegung ausführen, deutlich schneller hinsichtlich der einzustellenden Unwucht zu regeln. Der Platzbedarf des Schwingungserzeugers ist ebenfalls außerordentlich positiv beeinflußt, so daß beispielsweise der gesamte Schwingungserzeuger mit seinem Antrieb und allen notwendigen Teilen kompakt und zentral unterhalb eines Rütteltisches in einer Rüttelstation einer Steinformmaschine einzubauen ist.In the vibration generator according to the invention is only still a motorized central drive unit necessary, the the endless drive body, preferably toothed belt, the drives the inner and outer unbalanced mass. To do this conveniently the motorized central drive unit two Outputs with drive gears so that the endless drive body without the need for more elaborate electronic control means with exactly matching Speed must be driven. About the endless drive body the inner and outer unbalance mass the unbalance adjustment can be carried out by the additional movement of an endless drive body or by opposing additional movements of both endless drive bodies the otherwise in the same direction and with the same Speed rotating inner unbalance mass and outer unbalanced mass rotated relative to each other will. The total parts required including the drive means are conventional Vibration generators significantly reduced, resulting in the total production costs of the vibration generator and thus also one equipped with such a vibration generator Stone molding machine are significantly reduced. Nevertheless, the vibrator works extremely well reliable and is particularly in training, in which both the inner and the outer unbalance mass perform an additional rotary movement, clearly faster with regard to the unbalance to be set regulate. The space requirement of the vibration generator is also extremely positively influenced, so that for example the entire vibration generator with its drive and all necessary parts compact and central below a vibrating table in a vibrating station Stone molding machine is to be installed.
Bevorzugtermaßen wird zur Einleitung der Zusatzbewegung die motorische Zentralantriebseinheit translatorisch bewegt bzw. verfahren. Die beiden Endlosantriebsmittel sind von dieser zentralen motorischen Antriebseinheit vorzugsweise gegensinnig angetrieben, jedoch über Umlenkräder und Übergreifen bzw. Untergreifen von Zahnrädern derart geführt, daß einander zugeordnete innere und äußere Unwuchtmassen gleichsinnig rotieren und benachbart dem Schwingungserzeuger angeordnete bzw. vorgesehene Unwuchtkörper gegensinnig rotieren. Wird die motorische Zentralantriebseinheit nunmehr in eine Richtung bewegt, erfährt ein Endlosantriebskörper eine zu seiner Antriebsbewegungsrichtung gleichgerichtete Zusatzbewegung, der andere Antriebskörper jedoch eine zu seiner Antriebsbewegungsrichtung gegensinnig ausgerichtete Zusatzbewegung. Das führt automatisch zu einer überlagerten Winkelverstellung sowohl der inneren als auch der äußeren Unwuchtmasse.It is preferred to initiate the additional movement the motorized central drive unit moves translationally or proceed. The two endless drive means are from this central motor drive unit preferably driven in opposite directions, but via deflection wheels and Overlap or underlap of gears guided in such a way that associated internal and external unbalanced masses rotate in the same direction and adjacent to it Vibration generator arranged or provided imbalance body rotate in opposite directions. Will the motor Central drive unit now moved in one direction, an endless drive body experiences a direction of its drive movement rectified additional movement, the other drive bodies, however, one to its drive movement direction oppositely oriented additional movement. This automatically leads to a superimposed angle adjustment both the inner and outer unbalance mass.
Zweckmäßigerweise sind die inneren Unwuchtmasse und die äußere Unwuchtmasse wie bei bekannten Schwingungserzeugern derart ausgebildet, daß die äußere Unwuchtmasse die innere Unwuchtmasse übergreifen kann. Es ist allerdings ebenfalls möglich, daß z.B. die innere Unwuchtmasse mit der äußeren Unwuchtmasse kämmt.The internal unbalance mass and the are expedient outer unbalance mass as in known vibration generators formed such that the outer unbalanced mass the inner Unbalance mass can spread. However, it is also possible that e.g. the inner unbalance mass with the outer Unbalanced mass combs.

Die in den Fig. 1 und 2 schematisch veranschaulichte
Steinformmaschine hat ein Unterlagebrett 1, auf dem Betonprodukte
hergestellt werden. Das Unterlagebrett 1 liegt
auf einem Rütteltisch 2, dessen vertikale Schwingungen
durch die Rüttelstationen 3 erzeugt werden. Dazu hat die
Rüttelstation 3 einen Schwingungserzeuger mit einem
zentralen Antriebsmotor 4, der horizontal zu verschieben
ist. Der Antriebsmotor 4 hat zu diesem Zweck an beiden
Seiten auf der durchgehenden Antriebswelle Zahnriemenräder,
an denen die beiden Zahnriemen 4.1

Übergreifen/Untergreifen der Zahnräder derart geführt

9 und 10 (inneren Unwuchtmassen/äußeren Unwuchtmassen) antreiben.
Die Zahnriemen 4.1 umschlingen die Zahnscheiben 6
so, daß die vier Unwuchten 7, 8, 9 und 10 trotz der gegenläufigen
Antriebsbewegungen der Zahnriemen 4.1 die für
die Rüttelung richtige Drehrichtung haben. Die Unwuchten 7
und 8 drehen gleichgerichtet, ebenfalls die Unwuchten 9
und 10. Insgesamt sind die Drehrichtungen der Unwuchten 7
und 8 einerseits und die Unwuchten 9 und 10 andererseits
exakt zueinander gegenläufig.The one illustrated schematically in Figs. 1 and 2

Wird nun der Antriebsmotor 4 in Richtung der Pfeile 13
verschoben, so ergibt sich eine Relativbewegung der Zahnriemen
4. 1 in Richtung der Pfeile 14, wodurch - unabhängig
von der Drehung der Motorwellen und der Bewegungsrichtung
5 der Zahnriemen - die Unwuchtmassen relativ
zueinander so verdreht werden, so daß schließlich die Anordnung
gemäß den Fig. 6 und 7 mit maximaler Rüttelkraft
erreicht wird.Now the

kann auch ein Hydraulikzylinder oder ein
anderes geeignetes Element eingesetzt werden.The displacement of the
Alternativ ist es ebenfalls möglich, wie dies Fig. 8 veranschaulicht, z.B. einzelne Umlenkräder derart lageversetzbar anzuordnen, daß die Zusatzbewegung der Zahnriemen über eine Bewegung eines Umlenkrades erfolgt. Gezeigt ist die Abstützung über einen Schwenkebel.Alternatively, it is also possible, as illustrated in FIG. 8, e.g. individual deflection wheels so displaceable to arrange that the additional movement of the timing belt via a movement of a deflection wheel. Is shown the support via a swivel lever.
