Description

Die Erfindung betrifft eine Taumelsiebmaschine mit einem ortsfesten Untergestell und einem vom Untergestell getragenen Siebaufbau. Es sind zahlreiche Taumelsiebmaschinen aus der Literatur bekannt geworden, siehe zum Beispiel DE 33 43 615, DE 42 36 349, DE 299 01 833 U1.The invention relates to a tumbler screening machine with a stationary Underframe and a sieve structure supported by the underframe. There are numerous tumble screening machines have become known from the literature, see for example DE 33 43 615, DE 42 36 349, DE 299 01 833 U1.

Dokument DE 299 01 833 beschreibt eine Taumelsiebmaschine gemäß Oberbegriff des Anspruchs 1.Document DE 299 01 833 describes a tumbler screening machine according to the preamble of claim 1.

Der Siebaufbau führt im Betrieb eine taumelnde Bewegung aus. Er umfaßt eine Bodenwanne, einen oder mehrere Siebeinsätze, eine entsprechende Anzahl von Zwischenzylindern zwischen zwei einander benachbarten Siebeinsätzen sowie eine Haube. Die Zahl der Siebeinsätze und der Zwischenzylinder hängt von den Fraktionen ab, die man mit einer solchen Maschine erzielen will. Die Siebeinsätze umfassen in bekannter Weise Siebe mit unterschiedlichen Maschenweiten.The sieve assembly makes a wobbling movement during operation. It includes a floor pan, one or more sieve inserts, a corresponding one Number of intermediate cylinders between two adjacent ones Sieve inserts and a hood. The number of sieve inserts and the Intermediate cylinder depends on the fractions that you use with such Machine wants to achieve. The sieve inserts comprise sieves in a known manner with different mesh sizes.

Gewisse Teile der Maschine unterliegen dem Verschleiß, insbesondere die Siebe. Außerdem müssen Wartungsarbeiten durchgeführt werden, abhängig von dem zu behandelnden Gut, das Verschleiß und Verschmutzung nach sich ziehen kann.Certain parts of the machine are subject to wear, especially that Sieves. In addition, maintenance work must be carried out, depending of the goods to be treated, the wear and soiling can pull.

Es ist allen zwangsangetriebenen Taumelsiebmaschinen eigen, daß der schwingende Teil - Bodenwanne, Siebeinsätze, Zwischenzylinder und Haube - während des Betriebes eine taumelnde Bewegung ausführen, hervorgerufen durch den exzentrischen Antrieb und die Neigung des Antriebszapfens des schwingenden Teiles. Die taumelnde Bewegung wird in zwei Ebenen ausgeführt. Dabei sind die verschiedenen Parameter der Taumelbewegung auf das zu behandelnde Gut einstellbar.It is common to all positive driven tumbler screens that the vibrating part - floor pan, sieve inserts, intermediate cylinder and hood - Carry out a wobbling movement during operation due to the eccentric drive and the inclination of the drive pin of the vibrating part. The wobbling movement is on two levels executed. Here are the various parameters of the wobble motion adjustable to the goods to be treated.

Der schwingende Teil ist modular aufgebaut Die Einzelteile müssen zum Zwecke der Inspektion, der Reinigung oder des Siebwechsels von Zeit zu Zeit demontiert werden. Die Demontage besteht darin, daß die die Einzelteile verbindenden Zuganker gelöst und die betreffenden Einzelteile des schwingungsfähigen Siebaufbaus von Hand abgehoben werden.The vibrating part has a modular structure Purposes of inspection, cleaning or changing the screen from time to time be dismantled. The disassembly is that the individual parts connecting tie rod solved and the individual parts of the vibrating sieve structure can be lifted by hand.

In der Praxis versucht man, die manuelle Arbeit zu erleichtern, beispielsweise durch die Anwendung von Seil- oder Kettenzügen. Hierzu ist aber stets eine Anhängevorrichtung notwendig. Diese befindet sich oberhalb der Maschine. Ein Problem besteht dabei in folgendem: der schwingende Teil hat beim Abschalten der Maschine von Fall zu Fall jeweils eine andere Position innerhalb der genannten Ebenen. Die Anhängevorrichtung hingegen befindet sich an ein- und derselben Stelle, in Bezug auf die Vertikalachse des ortsfesten Untergestelles bezogen. Dies bedeutet folgendes: wenn ein Abheben des schwingenden Teiles nach einer gewissen Zeitspanne beabsichtigt ist, so muß der schwingende Teil von Hand immer wieder erneut auf die Anhängevorrichtung ausgerichtet werden.In practice, one tries to make manual work easier, for example by using rope or chain hoists. But there is always one Towbar necessary. This is located above the machine. There is a problem with the following: the vibrating part has the Switch off the machine from case to case in a different position within the levels mentioned. The hitch, however, is in one and the same place, with respect to the vertical axis of the stationary base covered. This means the following: if a Lifting off the vibrating part after a certain period of time is intended, the vibrating part must be repeated again and again by hand be aligned with the hitch.

DE 299 01 833 U1 beschreibt eine Taumelsiebmaschine mit einer Hubeinrichtung, die an dem schwingenden Teil ständig fest installiert ist. Damit wird das Problem gelöst, das sich aus der jeweils unterschiedlichen Position des schwingenden Teiles ergibt.DE 299 01 833 U1 describes a tumbler screening machine with a Lifting device that is permanently installed on the vibrating part. This solves the problem arising from the different Position of the vibrating part results.

Die Lösung hat jedoch gravierende Nachteile:

  • die Hubvorrichtung weist eine erhebliche Masse auf. Diese schwingt beim Betrieb der Maschine stets mit Dabei treten erhebliche dynamische Kräfte auf, die Maschine muß entsprechend dimensioniert werden.
  • bei Betreibern, die mehrere Maschinen im Einsatz haben, wird eine solche Einrichtung für jede einzelne Maschine benötigt
  • die Energiezufuhrleitungen zum schwingenden Teil unterliegen einem erheblichen Verschleiß.
  • der Ein- und Ausbau der Siebeinsätze unterliegt räumlichen Beschränkungen, indem er nur in gewissen Richtungen möglich ist.
  • ein nachträgliches Verstellen der Auslaufposition, etwa durch Verdrehen der Zylinder - ist nicht möglich.
However, the solution has serious disadvantages:
  • the lifting device has a considerable mass. This always vibrates during operation of the machine. Considerable dynamic forces occur, the machine must be dimensioned accordingly.
  • for operators who use several machines, such a facility is required for each individual machine
  • the power supply lines to the vibrating part are subject to considerable wear.
  • the installation and removal of the sieve inserts is subject to space restrictions, as it is only possible in certain directions.
  • a subsequent adjustment of the outlet position, for example by turning the cylinder - is not possible.

Der Erfindung liegt die Aufgabe zugrunde, eine Taumelsiebmaschine anzugeben, die diese Nachteile vermeidetThe invention has for its object a tumble screening machine specify which avoids these disadvantages

Diese Aufgabe wird durch die Merkmale von Anspruch 1 gelöst.This object is solved by the features of claim 1.

Dem gemäß weist die erfindungsgemäße Taumelsiebmaschine eine Hubvorrichtung auf, die am schwingenden Teil der Maschine im Bedarfsfall andockbar ist. Die Hubvorrichtung ist somit nicht ständig mit dem schwingenden Teil der Maschine fest verbunden, sondern wird erst bei Bedarf an diesem schwingenden Teil befestigt, das heißt dann, wenn Wartungs-Reparatur- oder Austauscharbeiten vorzunehmen sind, selbstverständlich im Stillstand.Accordingly, the tumbler screening machine according to the invention has a Lifting device on the vibrating part of the machine if necessary is dockable. The lifting device is therefore not always with the vibrating part of the machine is firmly connected, but is only when necessary attached to this vibrating part, that is when maintenance repair or exchange work, of course in the Standstill.

Dabei kommt als Hubvorrichtung in erster Linie eine pneumatische oder hydraulische Einheit in Betracht, aber auch eine elektromotorische Einheit.The main lifting device is a pneumatic or hydraulic unit into consideration, but also an electromotive unit.

Wählt man eine pneumatische oder hydraulische Hubvorrichtung mit einem Zylinder und einem Kolben, so werden Vorkehrungen getroffen, um den Zylinder leicht und schnell an der Bodenwanne des schwingenden Teiles andocken zu können. In angedocktem Zustand läßt sich der Kolben beziehungsweise eine hieran befestigte Kolbenstange ausfahren, um die darüber befindlichen Teile abzuheben. If you choose a pneumatic or hydraulic lifting device with a Cylinder and a piston, precautions are taken to the Cylinder easily and quickly on the floor pan of the vibrating part to be able to dock. The piston can be docked or extend a piston rod attached to the lift off any parts above.

Auch andere Arten von Hubvorrichtungen sind denkbar, beispielsweise eine teleskopische Einheit. Dabei ist es auch möglich, die Anordnung derart zu treffen, das Siebdecks selektiv abgehoben werden. Hat beispielsweise eine Taumelmaschine fünf Siebdecks, so können die drei unteren in ihrer Normalposition verbleiben, und nur die beiden oberen abgehoben werden.Other types of lifting devices are also conceivable, for example one telescopic unit. It is also possible to arrange the arrangement in this way the screen decks are lifted off selectively. For example, has one Tumbler five screen decks, so the three lower ones in your Normal position remain, and only the top two are lifted off.

Durch die Erfindung wird im einzelnen folgendes erreicht Da die Hubvorrichtung normalerweise, das heißt während des Betriebes, nicht am schwingenden Teil befestigt ist, tritt das oben genannte Problem des Vergrößems der Schwungmasse gar nicht auf. Hieraus folgt, daß die einzelnen Bauteile der Maschine nicht verstärkt werden müssen.In detail, the following is achieved by the invention Since the lifting device normally, i.e. during operation, does not attached to the vibrating part, the above problem of The inertia does not increase at all. It follows that the individual components of the machine do not have to be reinforced.

Ein weiterer Vorteil liegt darin, daß die Hubvorrichtung bei einer Mehrzahl von Taumelsiebmaschinen verwendet werden kann. Anders ausgedrückt: für mehrere Taumelsiebmaschinen braucht nur eine einzige Hubvorrichtung bereitzustehen.Another advantage is that the lifting device with a plurality of Tumbler screens can be used. In other words: for multiple tumbler screens only need a single lifting device stand by.

Ferner braucht beim Andocken der erfindungsgemäßen Hubvorrichtung nicht ein mühsames und zeitraubendes Positionieren von Hand vorgenommen zu werden.Furthermore, does not need when docking the lifting device according to the invention a tedious and time-consuming positioning by hand become.

Die Hubvorrichtung kann auch an vorhandenen Maschinen ohne deren Veränderung angedockt werden. Die Andockstellen sind die Befestigungsstellen der vorhandenen Zuganker.The lifting device can also be used on existing machines without them Change can be docked. The docking points are those Fastening points of the existing tie rods.

Die Erfindung ist anhand der Zeichnung näher erläutert. Darin ist im einzelnen folgendes dargestellt:

Die in Figur 1 gezeigte Taumelsiebmaschine weist ein starres Untergestell 1 auf sowie einen von diesem getragenen, bei Betrieb schwingenden Siebaufbau 2.The tumbler screening machine shown in FIG. 1 has a rigid base frame 1 on and one carried by it and vibrating during operation Sieve structure 2.

Das Untergestell umfaßt unter anderem einen Sockel 1.1, einen Motor 1.2 sowie Gummistäbe 1.3, die einerseits am Sockel 1.1 und andererseits am Siebaufbau 2 angreifen.The base frame includes a base 1.1, a motor 1.2 and rubber rods 1.3, on the one hand on the base 1.1 and on the other hand on Attack sieve assembly 2.

Der Siebaufbau 2 umfaßt eine Bodenwanne 2.1, einen ersten Siebeinsatz 2.2, einen Zwischenzylinder 2.3, einen weiteren Siebeinsatz 2.4, und so weiter, sowie schließlich eine Haube 2.5.The screen structure 2 comprises a floor pan 2.1, a first screen insert 2.2, an intermediate cylinder 2.3, another sieve insert 2.4, and so on, and finally a hood 2.5.

Gemäß der Erfindung ist eine Hubvorrichtung 3 vorgesehen. Diese ist im Normalzustand - das heißt während des Betriebes der Taumelsiebmaschine - von der Maschine entfernt.According to the invention, a lifting device 3 is provided. This is in Normal state - that is, during the operation of the tumbler screening machine - away from the machine.

Die Hubvorrichtung 3 umfaßt als wesentliche Bauteile einen Hubzylinder 3.1 und eine Hubstange 3.2. Es ist eine Halterung 4 vorgesehen. Diese ist einerseits am Wannenboden 2.1 befestigt, andererseits am Hubzylinder 3.1. Im vorliegenden Falle umfaßt die Halterung 4 eine Buchse 4.1, durch die die Hubstange 3.2 hindurchgeführt ist. The lifting device 3 comprises a lifting cylinder 3.1 as essential components and a lifting rod 3.2. A holder 4 is provided. This is on the one hand attached to the tub floor 2.1, on the other hand to the lifting cylinder 3.1. In the present case, the holder 4 comprises a socket 4.1 through which the Lift rod 3.2 is passed.

Die Hubstange 3.2 ist an ihrem oberen Ende über eine Lasche 5.1 mit Steckbolzen 5.2 an der Haube 2.5 fixiert - wohlgemerkt nur dann, wenn die Hubvorrichtung 3 gebraucht wird. Normalerweise, das heißt während des Betriebes der Maschine, sind die genannten Verbindungen zwischen Hubstange 3.2 einerseits sowie Halterung 4 und Lasche 5.1 mit Steckbolzen 5.2 gelöst.The lifting rod 3.2 is at its upper end with a tab 5.1 Pin 5.2 fixed to the hood 2.5 - mind you, only if the Lifting device 3 is needed. Usually, that is during the Operation of the machine, are the connections between Lifting rod 3.2 on the one hand and bracket 4 and bracket 5.1 with plug pins 5.2 solved.

An der Hubstange sind mehrere Schwenkeinrichtungen 6.1 bis 6.4 angelenkt. Jede Schwenkeinrichtung umfaßt eine Schelle, die die Hubstange 3.2 umschließt, femer einen Schwenkarm, zum Beispiel den Schwenkarm 6.1.1 von Schwenkeinrichtung 6.1 sowie eine Stellschraube 6.1.2 zum Fixieren der Schwenkeinrichtung in einer bestimmten Winkelposition. In der Darstellung ist die Schwenkeinrichtung 6.1 derart verschwenkt, daß sie am Zwischenzylinder 2.3 angreift. Wird die Hubstange 3.2 aus dem Hubzylinder 3.1 ausgefahren, so führt dies zu einer Mitnahme von Zwischenzylinder 2.3 sowie allen hierauf ruhenden Bauteilen des Siebaufbaus bis zur Haube 2.5.Several swivel devices 6.1 to 6.4 are articulated on the lifting rod. Each swivel device comprises a clamp which the lifting rod 3.2 encloses also a swivel arm, for example the swivel arm 6.1.1 of swivel device 6.1 and a set screw 6.1.2 for fixing the Swivel device in a certain angular position. In the illustration is the pivoting device 6.1 is pivoted such that it is on the intermediate cylinder 2.3 attacks. If the lifting rod 3.2 is extended from the lifting cylinder 3.1, this leads to entrainment of intermediate cylinder 2.3 and all of it stationary components of the sieve structure up to the hood 2.5.

Die in Figur 2 gezeigte Taumelsiebmaschine ist im Prinzip gleich aufgebaut, wie die in Figur 1 gezeigte. Die Abstände zwischen den einzelnen Schwenkeinrichtungen 6.1 bis 6.4 sind jedoch unterschiedlich groß - siehe die Maße a1 bis a3. Hierdurch wird folgendes bewirkt: greift beispielsweise die untere Schwenkeinrichtung 6.1 am unteren Zwischenzylinder 2.3 an, so werden zwar die darüber liegenden Schwenkeinrichtungen 6.2, 6.3 und 6.4 ebenfalls angehoben, greifen jedoch zunächst noch nicht an den darüber befindlichen Modulen an. Dies geht darauf zurück, daß die Abstände zwischen der Oberkante der einzelnen Schwenkeinrichtung und der Unterkante des nachfolgenden Siebeinsatzes von unten nach oben gesehen zunehmen. Siehe die Maße b1, b2, b3, b4. The tumble screening machine shown in FIG. 2 is constructed in principle in the same way as that shown in FIG. 1. However, the distances between the individual swivel devices 6.1 to 6.4 are of different sizes - see dimensions a 1 to a 3 . This has the following effect: if, for example, the lower swivel device 6.1 engages the lower intermediate cylinder 2.3, the swivel devices 6.2, 6.3 and 6.4 above it are also raised, but initially do not yet attack the modules located above them. This is due to the fact that the distances between the upper edge of the individual pivoting device and the lower edge of the subsequent sieve insert increase from bottom to top. See the dimensions b1, b2, b3, b4.

Bei der in Figur 3 dargestellten Taumelsiebmaschine sind vier angedockte Hubvorrichtungen 3, 13, 23, 33 vorgesehen. Alle vier Hubvorrichtungen arbeiten synchron und wirken auf ein- und dasselbe Modul.In the tumbler screening machine shown in Figure 3 there are four docked Lifting devices 3, 13, 23, 33 are provided. All four lifting devices work synchronously and act on one and the same module.

Dabei ist es vorteilhaft, die Hubvorrichtungen diagonal einander gegenüberliegend anzuordnen, so daß der entsprechende Siebeinsatz nach zwei Seiten zwischen den Hubstangen ausgezogen werden kann. Wie man sieht, lassen sich die einzelnen Hubvorrichtungen auch an jeder anderen Stelle des Umfanges der Zuganker andocken, je nach Position der Ausläufe beziehungsweise sonstiger baulicher Gegebenheiten. Die Ausbaurichtung der Siebeinsätze ist somit nach Bedarf frei wählbar.It is advantageous if the lifting devices are diagonal to each other to be arranged opposite, so that the corresponding sieve insert after two sides between the lifting rods can be pulled out. How one see, the individual lifting devices can also be used on any other Dock the position of the circumference of the tie rods, depending on the position of the outlets or other structural conditions. The expansion direction of the Sieve inserts can thus be freely selected as required.

In Figur 4 erkennt man genauer die Zuordnung von Hubvorrichtung 3 und Taumelsiebmaschine. Der Hubzylinder 3.1 ist dabei an die Bodenwanne 2.1 angedockt Zu diesem Zwecke ist der Hubzylinder mit Schellen 3.1.2, 3.1.3 versehen, die mittels Schrauben rasch und einfach an der Bodenwanne beziehungsweise an einer entsprechenden Lasche angeschraubt werden können.In Figure 4 you can see the assignment of lifting device 3 and Tumbler. The lifting cylinder 3.1 is on the floor pan 2.1 Docked for this purpose the lifting cylinder with clamps 3.1.2, 3.1.3 provided by means of screws on the floor pan quickly and easily or screwed to a corresponding tab can.

Man erkennt eine Schwenkeinrichtung 6.1, die an einem Modul angreift. Die Schwenkeinrichtung 6.1 ruht auf einem Querbolzen 3.2.1, der bei Ausfahren der Hubstange 3.2 die Schwenkeinrichtung 6.1 und damit auch das zugehörende Modul mitnimmt. Siehe Pfeil A.A swivel device 6.1 can be seen, which acts on a module. The Swivel device 6.1 rests on a cross pin 3.2.1, which extends when extending the lifting rod 3.2, the swivel device 6.1 and thus also that associated module. See arrow A.
