Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Entlee­ren eines Fasses mit hochviskosem Inhalt mit einem Preßkol­ben, welcher in das Faß einpreßbar ist.The invention relates to a device for emptying a barrel with a highly viscous content with a plunger which can be pressed into the barrel.

Das Entleeren von Fässern oder ähnlichen Gebinden, welche mit hochviskosen Stoffen, beispielsweise einer Silikonpaste gefüllt sind, erfolgt üblicherweise dadurch, daß ein Preß­kolben in das geöffnete Faß eingedrückt wird. Durch Leitun­gen in dem Preßkolben kann der hochviskose Stoff aus dem Faß ausgepreßt und gefördert werden. Es ist auch möglich, als Teil des Preßkolbens oder anstelle des Preßkolbens zur Ent­leerung des Fasses dessen Deckel in den Innenraum des Fasses einzudrücken.The emptying of drums or similar containers, which are filled with highly viscous substances, for example a silicone paste, usually takes place in that a plunger is pressed into the opened drum. The highly viscous substance can be pressed out of the barrel and conveyed through lines in the plunger. It is also possible, as part of the plunger or instead of the plunger to empty the barrel, to press its cover into the interior of the barrel.

In Abhängigkeit von der Viskosität des zu entleerenden Stof­fes ist ein erheblicher Druck erforderlich, um diesen in die Rohrleitung zu pressen. Daraus ergibt sich, daß das Faß wäh­rend des Entleerungsvorganges sehr hohen mechanischen Anfor­derungen ausgesetzt ist.Depending on the viscosity of the substance to be emptied, considerable pressure is required to press it into the pipeline. It follows that the barrel is exposed to very high mechanical requirements during the emptying process.

Aus Gewichts- und Kostengründen werden Fässer üblicherweise sehr dünnwandig ausgebildet und besitzen eine Stabilität, welche gerade ausreichend ist, um eine Beschädigung des Fas­ses während des Transportes zu vermeiden. Für die beim Ent­leeren des Fasses auftretenden Belastungen ist dieses jedoch nicht ausgelegt. Beispielsweise bestehen derartige Fässer aus Kunststoff oder Pappe.For weight and cost reasons, barrels are usually very thin-walled and have a stability that is just sufficient to avoid damaging the barrel during transport. However, this is not designed for the loads that occur when emptying the drum. For example, such barrels are made of plastic or cardboard.

Um zu verhindern, daß das Faß durch den hohen Entleerungs­druck platzt, ist es aus dem Stand der Technik bekannt, ge­teilte metallische Manschetten oder Halbschalen, beispiels­weise aus Blech um das Faß zu legen und dieses dadurch zu ummanteln und abzustützen. Als nachteilig erweist es sich dabei, daß das Anbringen und Verschließen dieser Halbschalen oder Manschetten sehr aufwendig ist und ein beträchtliches Maß an Handarbeit erfordert. Weiterhin erweist es sich als nachteilig, daß die Manschetten oder Halbschalen in exakter Weise an die Außenabmessungen des Fasses angepaßt werden müssen, so daß bei einer Vorrichtung, auf welcher unter­schiedlichste Faßgrößen entleert werden sollen eine Vielzahl derartiger Blechmanschetten oder Halbschalen benötigt wer­den.In order to prevent the barrel from bursting due to the high emptying pressure, it is known from the prior art to place split metallic sleeves or half-shells, for example made of sheet metal, around the barrel and thereby to coat and support it. It turns out to be disadvantageous the fact that the attachment and closing of these half-shells or cuffs is very complex and requires a considerable amount of manual work. Furthermore, it proves to be disadvantageous that the sleeves or half-shells have to be adapted exactly to the outer dimensions of the drum, so that a plurality of such metal sleeves or half-shells are required in a device on which the most varied drum sizes are to be emptied.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, welche bei einfachem Aufbau und einfacher, betriebssicherer Anwendbarkeit die Entleerung von Fässern unterschiedlicher Größe ermöglicht und dabei insbesondere automatisierbar anwendbar ist.The invention has for its object to provide a device of the type mentioned, which allows the emptying of drums of different sizes with a simple structure and simple, reliable application and is particularly applicable automated.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß das Faß auf einem Drehtisch aufsetzbar ist und daß zur Umschlingung des Fasses an dem Drehtisch ein Endbereich eines Umschlin­gungselementes befestigt ist, welches auf einer Trommel auf- und abspulbar ist.According to the invention the object is achieved in that the barrel can be placed on a turntable and that an end region of a looping element is fastened to the barrel on the turntable and can be wound and unwound on a drum.

Die erfindungsgemäße Vorrichtung zeichnet sich durch eine Reihe erheblicher Vorteile aus. Da das Faß auf dem Drehtisch aufsetzbar ist, ist es möglich, dieses mittels des Umschlin­gungselementes vollständig zu umschlingen und an seinem Aus­senumfang abzustützen. Da das Umschlingungselement flexibel ist, kann es sich den jeweiligen Außenkonturen des Fasses anpassen. Es ist deshalb nicht erforderlich, die Vorrichtung für unterschiedliche Formen und Abmessungen von Fässern um­zurüsten, vielmehr können diese in beliebiger Abfolge ent­leert werden. Somit lassen sich insbesondere auch Abmes­sungstoleranzen und/oder geringfügige Beschädigungen des ge­füllten Fasses ausgleichen.The device according to the invention is distinguished by a number of considerable advantages. Since the barrel can be placed on the rotary table, it is possible to completely wrap it around by means of the looping element and to support it on its outer circumference. Since the wrapping element is flexible, it can adapt to the respective outer contours of the barrel. It is therefore not necessary to retrofit the device for different shapes and dimensions of barrels, rather they can be emptied in any order. In this way, dimensional tolerances and / or minor damage to the filled barrel can also be compensated for.

Da das flexible Umschlingungselement auf einer Trommel auf- und abspulbar ist, kann die Umschlingung und Freigabe des Fasses automatisiert werden, ohne daß hierzu weitere Hand­ griffe eines Bedienungspersonales erforderlich wären.Since the flexible wrapping element can be wound and unwound on a drum, the wrapping and releasing of the barrel can be automated without any further hand handles of an operator would be required.

Erfindungsgemäß kann das flexible Umschlingungselement in Form eines Seiles, eines Drahtbandes oder eines aus Einzel­elementen bestehenden, kettenartigen Umschlingungselementes ausgebildet sein.According to the invention, the flexible wrapping element can be designed in the form of a rope, a wire band or a chain-like wrapping element consisting of individual elements.

Bevorzugterweise ist zwischen der Trommel und dem Drehtisch ein Führungselement für das Umschlingungselement angeordnet, um dessen vertikale Führung sicherzustellen. Hierdurch wird erreicht, daß das Umschlingungselement in zueinander benach­barten Lagen auf der Außenfläche des Fasses aufgewickelt wird. Die einzelnen Lagen des Umschlingungselementes können direkt aneinander grenzend oder zueinander beabstandet sein.A guide element for the wrapping element is preferably arranged between the drum and the rotary table in order to ensure its vertical guidance. This ensures that the wrapping element is wound in mutually adjacent layers on the outer surface of the barrel. The individual layers of the wrapping element can be directly adjacent to one another or spaced apart.

Das Führungselement umfaßt bevorzugterweise eine höhenver­stellbare Spindelmutter, wobei es günstig ist, wenn die Spindelmutter mittels einer Gewindespindel bei jeder Umdre­hung des Drehtisches um im wesentlichen die Breite des Um­schlingungselementes höhenveränderbar ist. Es wird hierdurch automatisiert erreicht, daß das Umschlingungselement in ge­ordneter Weise auf dem Außenumfang des Fasses aufgerollt bzw. von diesem abgerollt wird.The guide element preferably comprises a height-adjustable spindle nut, it being favorable if the spindle nut can be changed in height by essentially the width of the looping element by means of a threaded spindle with each revolution of the turntable. It is hereby achieved automatically that the wrapping element is rolled up in an orderly manner on the outer circumference of the barrel or is unwound from it.

Der Drehtisch und die Gewindespindel sind bevorzugterweise miteinander antriebsverbunden, beispielsweise über einen Zahnradtrieb. Diese Ausgestaltungsform ermöglicht es auch, mittels nur eines einzigen Motors sowohl den Drehtisch als auch die Gewindespindel anzutreiben.The turntable and the threaded spindle are preferably drive-connected to one another, for example via a gear drive. This embodiment also makes it possible to drive both the turntable and the threaded spindle by means of a single motor.

Um zu verhindern, daß der Drehtisch bei dem Einpressen des Preßkolbens beschädigt wird und um insbesondere Beschädigun­gen der Lagerung des Drehtisches und dessen Antriebes zu vermeiden, ist vorgesehen, daß der Drehtisch axial bewegbar an einem Grundgestell gelagert ist und mittels eines elasti­schen Vorspannelementes von einer Auflagefläche des Grundge­stelles weg vorgespannt ist. Ohne axiale Preßkraft des Preß­kolbens 9 läßt sich somit der Drehtisch frei drehen, während bei Aufbringen einer Kraft durch den Preßkolben der Dreh­tisch gegen die Auflagefläche des Grundgestelles gedrückt wird. Hierdurch wird gleichzeitig verhindert, daß sich der Drehtisch und damit das Faß während des Auspreßvorganges drehen und daß dabei möglicherweise das flexible Umschlin­gungselement gelockert wird.In order to prevent the turntable from being damaged when the plunger is pressed in, and in particular to avoid damaging the storage of the turntable and its drive, it is provided that the turntable is mounted on a base frame so as to be axially movable and by means of an elastic prestressing element from a bearing surface of the Base frame is biased away. Without an axial pressing force of the plunger 9, the turntable can thus rotate freely while when a force is applied by the plunger, the turntable is pressed against the supporting surface of the base frame. This at the same time prevents the turntable and thus the barrel from rotating during the squeezing process and possibly the flexible wrap element being loosened in the process.

Um sicherzustellen, daß das Faß in geeigneter Weise auf dem Drehtisch befestigt ist, ist vorgesehen, daß zumindest eine lösbare Haltebacke an dem Drehtisch gelagert ist. Diese dient dazu, das Faß zu greifen und an dem Drehtisch zu ver­riegeln, beispielsweise durch Eingriff der Haltebacke in einen Bodenflansch oder einen Verstärkungsrand des Fasses 1. Die Haltebacke wird bevorzugterweise mittels eines Druckmit­telzylinders betätigt, es ist insbesondere günstig, wenn zwei Haltebacken vorgesehen sind.In order to ensure that the barrel is fastened in a suitable manner on the turntable, it is provided that at least one releasable holding jaw is mounted on the turntable. This serves to grip the barrel and lock it on the rotary table, for example by engaging the holding jaw in a base flange or a reinforcing edge of the barrel 1. The holding jaw is preferably actuated by means of a pressure medium cylinder, it is particularly advantageous if two holding jaws are provided.

Die Trommel, auf welcher das flexible Umschlingungselement aufgewickelt bzw. von welcher es abspulbar ist, ist bevor­zugterweise mit einem separaten Antriebsmotor betriebsver­bunden, weiterhin ist es besonders günstig, wenn die Trommel mit Bremsmitteln versehen ist. Es kann hierbei auch der An­triebsmotor als Bremse dienen, um eine ausreichende Spannung des Umschlingungselementes bei der Umwicklung des Fasses zu gewährleisten.The drum, on which the flexible wrap element is wound or from which it can be unwound, is preferably operationally connected to a separate drive motor; furthermore, it is particularly advantageous if the drum is provided with braking means. In this case, the drive motor can also serve as a brake in order to ensure sufficient tension of the wrapping element when wrapping the barrel.

Im folgenden wird die Erfindung anhand eines Ausführungsbei­spieles in Verbindung mit der Zeichnung beschrieben. Dabei zeigt:

  • Fig. 1 eine Seitenansicht, teils im Schnitt, der erfin­dungsgemäßen Vorrichtung und
  • Fig. 2 eine Draufsicht auf die in Fig. 1 gezeigte Vorrich­gung.
The invention is described below using an exemplary embodiment in conjunction with the drawing. It shows:
  • Fig. 1 is a side view, partly in section, of the device according to the invention and
  • Fig. 2 is a plan view of the device shown in Fig. 1.

In den Fig. 1 und 2 ist ein im wesentlichen zylindrisches Faß 1 dargestellt, welches mit einem dicht abschließenden Boden versehen ist, welcher mittels eines Verstärkungsrandes 3 mit dem zylindrischen Teil des Fasses 2 verbunden ist. Das Faß 1 ist in einem geöffneten Zustand dargestellt, die Fig. 1 zeigt oberhalb des Fasses in strichpunktierter Linie einen Preßkolben 9, welcher in den Innenraum des Fasses 1 einpreß­bar ist. Der Preßkolben 9 ist, wie aus dem Stand der Technik bekannt, mit zumindest einer Ausnehmung versehen, durch wel­che der Inhalt des Fasses 1 nach oben ausströmen kann, wenn der Kolben 9 in das Faß 1 eingepreßt wird.1 and 2, an essentially cylindrical barrel 1 is shown, which with a tightly fitting Bottom is provided, which is connected by means of a reinforcing edge 3 to the cylindrical part of the barrel 2. The barrel 1 is shown in an open state, FIG. 1 shows a plunger 9 above the barrel in a dash-dotted line, which can be pressed into the interior of the barrel 1. The plunger 9, as is known from the prior art, is provided with at least one recess through which the contents of the barrel 1 can flow out when the piston 9 is pressed into the barrel 1.

Die erfindungsgemäße Vorrichtung umfaßt ein Grundgestell 8, auf welchem ein um eine vertikale Achse drehbarer Drehtisch 2 gelagert ist. Der Drehtisch 2 umfaßt an seinem unteren Ende eine Welle 5, welche mittels Lagern 6 und 7 an dem Grundgestell 8 gelagert ist.The device according to the invention comprises a base frame 8 on which a turntable 2 rotatable about a vertical axis is mounted. The turntable 2 comprises at its lower end a shaft 5 which is mounted on the base frame 8 by means of bearings 6 and 7.

Der die Lager 6 und 7 aufnehmende Bereich des Grundgestelles 8 ist mit einer oberen Auflagefläche 13 versehen, gegen wel­che eine Unterfläche 10 des Drehtisches 2 in Anlage bringbar ist. Hierzu ist die Welle 5 axial verschiebbar gelagert und wird mittels eines Paares von Tellerfedern 11,12 nach oben vorgespannt. In dem in Fig. 1 gezeigten Zustand ist der Drehtisch 2 frei drehbar, durch eine Druckaufbringung mit­tels des Preßkolbens 9 wird der Drehtisch 2 gegen die Vor­spannkraft der Tellerfedern 11,12 nach unten verschoben, so daß die Unterfläche 10 gegen die Auflagefläche 13 anliegt. Hierdurch wird eine weitere Drehung des Drehtisches 2 blok­kiert. Gleichzeitig erfolgt eine Entlastung der Lager 6,7, um zu verhindern, daß diese durch den Axialdruck des Preß­kolbens 9 beschädigt oder zerstört werden.The area of the base frame 8 receiving the bearings 6 and 7 is provided with an upper bearing surface 13, against which a lower surface 10 of the rotary table 2 can be brought into contact. For this purpose, the shaft 5 is axially displaceable and is biased upwards by means of a pair of disc springs 11, 12. In the state shown in Fig. 1, the turntable 2 is freely rotatable, by applying pressure by means of the plunger 9, the turntable 2 is moved downward against the biasing force of the plate springs 11, 12 so that the lower surface 10 bears against the bearing surface 13. As a result, a further rotation of the turntable 2 is blocked. At the same time, the bearings 6, 7 are relieved in order to prevent them from being damaged or destroyed by the axial pressure of the plunger 9.

Das untere Ende der Welle 5 ist mit einem Zahnrad 16 be­triebsverbunden, welches mit einem Antriebszahnrad 15 kämmt, welches wiederum auf der Abtriebswelle eines an dem Grund­gestell 8 gelagerten Motors 14 sitzt. Mittels des Motors 14 ist somit der Drehtisch 2 drehbar.The lower end of the shaft 5 is operatively connected to a gear 16 which meshes with a drive gear 15, which in turn is seated on the output shaft of a motor 14 mounted on the base frame 8. The turntable 2 can thus be rotated by means of the motor 14.

Wie insbesondere aus Fig. 2 ersichtlich ist, sind an dem Drehtisch 2 zwei Haltebacken 4 gelagert, welche schwenkbar sind, um das Faß 1 bzw. dessen Verstärkungsrand 3 zu ergrei­fen oder freizugeben. Die Verschwenkung der Haltebacken 4 erfolgt um die Schwenklager 33. An den freien Schenkein der Haltebacken 4 sind über Bolzen 34 jeweils Schenkel 35 ge­lenkig angelenkt. Einer der Schenkel 35 ist mit einem Kolben 36 verbunden, welcher in einem Druckmittelzylinder 29 ver­schiebbar ist, während der andere Schenkel 35 direkt mit dem Druckmittelzylinder 29 verbunden ist. Eine Verschiebung des Kolbens 36, welcher mittels einer Feder 30 vorgespannt ist, führt somit zu einer Verschwenkung der beiden Haltebacken 4.As can be seen in particular from FIG. 2, the The rotary table 2 has two holding jaws 4 which are pivotable in order to grip or release the barrel 1 or its reinforcing edge 3. The pivoting of the holding jaws 4 takes place around the pivot bearing 33. Legs 35 are articulated in each case via bolts 34 to the free legs of the holding jaws 4. One of the legs 35 is connected to a piston 36 which is displaceable in a pressure medium cylinder 29, while the other leg 35 is connected directly to the pressure medium cylinder 29. A displacement of the piston 36, which is biased by a spring 30, thus leads to a pivoting of the two holding jaws 4.

Eine Druckmittelbeaufschlagung des Druckmittelzylinders 29 erfolgt über eine Öffnung 28, welche über eine nicht darge­stellte Leitung mit einer Bohrung 27 des Drehtisches 2 ver­bunden ist. Die Bohrung 27 mündet in eine zentrische Bohrung 26 in der Welle 5 des Drehtisches. Am unteren Ende der zen­trischen Bohrung 26 ist eine seitliche Bohrung 37 an der Welle 5 vorgesehen, welche in einen Ringkanal 38 mündet, welcher mit einer Bohrung 25 in Verbindung steht. Über die Bohrung 25 ist Druckmittel von einer nicht gezeigten Pumpe zuführbar bzw. Druckmittel ableitbar, um den Druckmittelzy­linder 29 zu betätigen.A pressure medium is applied to the pressure medium cylinder 29 via an opening 28 which is connected to a bore 27 of the rotary table 2 via a line (not shown). The bore 27 opens into a central bore 26 in the shaft 5 of the turntable. At the lower end of the central bore 26, a lateral bore 37 is provided on the shaft 5, which opens into an annular channel 38 which is connected to a bore 25. Pressure medium can be supplied from a pump (not shown) or pressure medium can be discharged via the bore 25 in order to actuate the pressure medium cylinder 29.

Bei dem gezeigten Ausführungsbeispiel bewirkt die Feder 30, daß die Haltebacken 4 nach außen in eine gelöste Stellung vorgespannt sind, wenn kein Druckmittel in dem Innenraum des Druckmittelzylinders 29 eingepreßt wird. Hierdurch erfolgt eine automatische Freigabe des Fasses 1 bei einem Nachlassen des Fluiddrucks.In the exemplary embodiment shown, the spring 30 causes the holding jaws 4 to be biased outwards into a released position when no pressure medium is pressed into the interior of the pressure medium cylinder 29. As a result, the barrel 1 is automatically released when the fluid pressure decreases.

An dem Grundgestell 8 ist weiterhin drehbar eine vertikale Gewindespindel 18 gelagert, welche an ihrem unteren Ende ein Zahnrad 17 trägt, welches mit dem Zahnrad 16 kämmt, so daß die Gewindespindel 18 bei einer Drehung des Drehtisches 2 ebenfalls in Drehung versetzt wird. Das Grundgestell 8 um­faßt oberhalb der Lager 39,40 der Gewindespindel, welche in einem zylindrischen Ansatz 41 des Grundgestelles 8 ange­ bracht sind, eine Kulissenführung 20, in welcher verschieb­bar eine Spindelmutter 19 geführt ist, die mit der Gewinde­spindel 18 in Eingriff ist. Eine Drehung der Gewindespindel 18 führt somit zu einer Verschiebung der Spindelmutter 19 in der Kulissenführung 20.On the base frame 8, a vertical threaded spindle 18 is also rotatably mounted, which carries at its lower end a gear 17 which meshes with the gear 16 so that the threaded spindle 18 is also rotated when the turntable 2 rotates. The base frame 8 comprises above the bearing 39, 40 of the threaded spindle, which is in a cylindrical extension 41 of the base frame 8 are brought, a link guide 20 in which a spindle nut 19 is slidably guided, which is in engagement with the threaded spindle 18. A rotation of the threaded spindle 18 thus leads to a displacement of the spindle nut 19 in the link guide 20.

Die Spindelmutter 19 lagert Führungsrollen 21,22, durch wel­che ein flexibles Umschlingungselement 23 durchleitbar ist. Das freie Ende des Umschlingungselementes 23 ist bei 42 an dem Drehtisch 2 befestigt.The spindle nut 19 supports guide rollers 21, 22 through which a flexible wrap element 23 can be passed. The free end of the wrapping element 23 is attached to the turntable 2 at 42.

Wie in den Fig. 1 und 2 gezeigt, ist an dem Grundgestell 8 benachbart zu der Gewindespindel 18 eine Trommel 24 drehbar gelagert, welche über ein Getriebe 31 mit einem Motor 32 be­triebsverbunden ist. Der Motor 32 kann sowohl zum Antrieb der Trommel 24 beim Aufwickeln des Umschlingungselementes 23 als auch als Bremse beim Abwickeln des Umschlingungselemen­tes 23 dienen.As shown in FIGS. 1 and 2, a drum 24 is rotatably mounted on the base frame 8 adjacent to the threaded spindle 18 and is operatively connected to a motor 32 via a gear 31. The motor 32 can serve both to drive the drum 24 when winding the wrapping element 23 and as a brake when unwinding the wrapping element 23.

Das elastische Umschlingungselement kann beispielsweise in Form eines Stahlseiles, eines Stahlbandes oder eines Glie­derelementes ausgebildet sein. Die Steigung der Gewindespin­del 18 sowie die Übersetzung der Zahnräder 16 und 17 sind so ausgebildet, daß bei einer vollständigen Drehung des Dreh­tisches 2 die Spindelmutter 19 im wesentlichen um den Betrag der Dicke des Umschlingungselementes 23 nach oben bzw. nach unten verschoben wird.The elastic wrap element can be designed, for example, in the form of a steel cable, a steel band or a link element. The pitch of the threaded spindle 18 and the translation of the gears 16 and 17 are designed such that when the turntable 2 is rotated completely, the spindle nut 19 is shifted up or down essentially by the amount of the thickness of the wrapping element 23.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, vielmehr ergeben sich für den Fachmann im Rahmen der Erfindung vielfälte Abwandlungs- und Modifikationsmög­lichkeiten.The invention is not limited to the exemplary embodiment shown, rather there are various modification and modification possibilities for the person skilled in the art within the scope of the invention.
