Description

Die vorliegende Erfindung bezieht sich auf Vorrichtungen zum Heben voll Fässern und im speziellen auf Vorrichtungen zum Heben von Fässern oder Behältern mit dem Zweck, viskose Produkte direkt innerhalb ihres Aufbereitungsbehälters aufzuheizen und aus diesein abzupumpen.The present invention relates to devices for lifting full drums and, in particular, to devices for lifting drums or containers with the purpose of heating and pumping viscous products directly within their processing container.

Es sind Vorrichtungen bekannt, bei denen ein Faß oder ein Behälter, in dem sich ein viskoses zur Aufbereitung vorgesehenes Produkt befindet, zwischen zwei pneumatischen Zylindern angeordnet wird, die wiederum eine Pumpenanordnung tragen. Diese Pumpenanordnung besteht aus einer Heizplatte, welche abgesenkt und in das Faß oder den Behälter eingeführt wird und die in Kontakt mit dein Produkt tritt, wobei gleichzeitig die Dichtigkeit zwischen dein Behälter und der Platte gesichert ist. Die Pumpe für das Produkt, welche fest auf der oberen Oberfläche der Platte angeordnet ist, kann entweder eine Kolben- oder eine Zahnradpumpe sein. Im ersten Falle wird die Pumpe durch einen Pneumatik- oder Hydraulikzylinder betätigt. Im zweiten Fall werden die Zahnräder durch einen Elektromotor oder durch einen Hydraulikmotor angetrieben. Die gesamte Baueinheit, bestehend aus Platte, Pumpe und Motor, wird durch die zwei Hydraulikzylinder vertikal bewegt, wobei zur Aufrechterhaltung der Pumpfunktion die Position der Anordnung immer den, Füllstand des Produktes innerhalb des Fasses oder des Behälters entspricht. Das verflüssigte Produkt wird aus dem Behälter abgepumpt und ausgehend von der Pumpe durch eine flexible, beheizte Leiteinrichtung zu einer anderen Maschine oder zu einem Extruder geleitet. Will man die Heizplatte aus dem Faß oder dem Behälter entfernen, so ist es notwendig, komprimierte Luft zwischen die Platte und das in dem Behälter enthaltene Produkt zu leiten, um einen Saugeffekt zu vermeiden.Devices are known in which a drum or a container, in which a viscous product intended for processing is located, is arranged between two pneumatic cylinders, which in turn carry a pump arrangement. This pump assembly consists of a heating plate which is lowered and inserted into the barrel or container and which comes into contact with your product, while at the same time ensuring the tightness between the container and the plate. The pump for the product, which is fixed on the upper surface of the plate, can be either a piston or a gear pump. In the first case, the pump is operated by a pneumatic or hydraulic cylinder. In the second case, the gears are driven by an electric motor or by a hydraulic motor. The entire assembly, consisting of plate, pump and motor, is moved vertically by the two hydraulic cylinders, whereby the position of the arrangement always corresponds to the level of the product inside the barrel or container in order to maintain the pump function. The liquefied product is pumped out of the container and, starting from the pump, through a flexible, heated guide device to another machine or passed to an extruder. If you want to remove the heating plate from the drum or the container, it is necessary to pass compressed air between the plate and the product contained in the container in order to avoid a suction effect.

Diese bekannte Faßhebevorrichtung zur Bearbeitung aufzubereitender Produkte hat verschiedene Nachteile. So besitzt die beschriebene, bekannte Vorrichtung ungeschützte bewegte Teile, die eine Verletzungsgefahr mitsichbringen. Weiterhin ist nachteilig, daß zur Ableitung des behandelten Produktes aus der Pumpe eine flexible Leitung notwendig ist, da hierdurch ein möglicherweise vorhandener Restdruck durch Dilatation der flexiblen Leitung verloren gehen kann. Das Einleiten von komprimierter Luft zur Extraktion der Heizplatte aus dem Behälter mit dem zu behandelnden Produkt birgt ein Sicherheitsproblem, da niemals vollständig sichergestellt sein kann, ob sich beim Verlassen des Behälters durch die Heizplatte nicht noch ein Druckluftpolster zwischen der Platte und dem Produkt befindet, das schlagartig entweicht, wenn die Heizplatte entfernt wird. Weiterhin ist es als nachteilig anzusehen, daß durch den Einsatz von zwei Pneumatikzylindern, die eine Plattform tragen, ein Verkanten der Heizplatte innerhalb des Behälters oder des Fasses eintreten kann, so daß die gesamte Vorrichtung blockiert. Kommt es aus irgendeinem Grunde zu einer Unterbrechung der Druckluftversorgung beim Extrahieren der Heizplatte aus dem Behälter mit dein zu behandelnden Produkt, kann es außerdem zu einem unkontrollierten und daher gefährlichen Absenken der Heizplatte in den Behälter kommen.This known drum lifting device for processing products to be processed has various disadvantages. Thus, the known device described has unprotected moving parts which entail a risk of injury. A further disadvantage is that a flexible line is necessary to discharge the treated product from the pump, since any residual pressure that may be present can be lost as a result of dilation of the flexible line. Introducing compressed air to extract the heating plate from the container with the product to be treated poses a safety problem, since it can never be completely guaranteed whether there is still a compressed air cushion between the plate and the product when the container exits the heating plate suddenly escapes when the heating plate is removed. Furthermore, it is to be regarded as disadvantageous that the use of two pneumatic cylinders, which carry a platform, can cause the heating plate to tilt inside the container or the barrel, so that the entire device is blocked. If for some reason there is an interruption in the compressed air supply when extracting the heating plate from the container with the product to be treated, it can also lead to an uncontrolled and therefore dangerous lowering of the heating plate into the container.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung vorzusehen, die die beschriebenen Nachteile des bekannten Standes der Technik behebt, die jedoch gleichzeitig eine effiziente Behandlung des aufzubereitenden Produktes in einem Behälter zuläßt.The object of the present invention is therefore to provide a device which overcomes the disadvantages of the known prior art described, but which at the same time permits efficient treatment of the product to be processed in a container.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, wobei zweckmäßige Ausführungsformen der Erfindung durch die Unteransprüche gekennzeichnet sind.This object is achieved by the characterizing features of claim 1, expedient embodiments of the invention being characterized by the subclaims.

Gemäß der vorliegenden Erfindung ist eine Vorrichtung vorgesehen, die von einem dem Stand der Technik entgegengesetzten Prinzip ausgeht. Hierbei ist ein Chassis vorgesehen, das sich aus Standelementen, oberen, vorzugsweise horizontalen, Halteelementen sowie aus vertikalen Stützelementen, die auf den Standelementen angeordnet sind und die die Halteelemente tragen, zusammensetzt. An den vertikalen Stützelementen des Chassis sind Leitschienen angeordnet. In diese Leitschienen greifen Halterungen linear entlang der Leitschienen verschiebbar ein, die wiederum einen Hebetisch tragen. Die Anordnung, bestehend aus den in Leitschienen laufenden Halterungen sowie aus dem Hebetisch, wird durch einen Bewegungszylinder, vorzugsweise einen Hydraulikzylinder, der einerseits an dem Chassis und andererseits an dem Hebetisch befestigt ist, auf und ab bewegt, wobei der Bewegungszylinder vorzugsweise zwischen dem Chassis und dem Hebetisch angeordnet ist, so daß die bewegten Teile im Normalfall der Bedienung nicht zugänglich sind.According to the present invention, a device is provided which is based on a principle opposite to the prior art. In this case, a chassis is provided which is composed of stand elements, upper, preferably horizontal, holding elements and vertical support elements which are arranged on the stand elements and which carry the holding elements. Guard rails are arranged on the vertical support elements of the chassis. Holders engage in these guide rails in a linearly displaceable manner along the guide rails, which in turn carry a lifting table. The arrangement, consisting of the brackets running in the guide rails and the lifting table, is moved up and down by a movement cylinder, preferably a hydraulic cylinder, which is attached on the one hand to the chassis and on the other hand to the lifting table, the movement cylinder preferably being arranged between the chassis and the lifting table, so that the moving parts do not normally operate are accessible.

An dem oberen Halteelement des Chassis ist eine aus einer Pumpe sowie einer Heizplatteneinrichtung bestehende Anordnung angebracht, die fest an dem Chassis montiert ist. Die Ausrichtung der Pumpe sowie der Heizplatte korrespondiert mit der Ausrichtung des Hebetisches, so daß in dem Fall, daß auf dein Hebetisch ein Behälter oder ein Faß mit einem zu behandelnden Produkt entsprechend angeordnet ist, beim Aufwärtsfahren des Hebetisches durch den Hydraulikzylinder die Heizplatte in den Behälter oder das Faß einfährt, so daß das Produkt aufbereitet und abgepumpt werden kann.On the upper holding element of the chassis, an arrangement consisting of a pump and a heating plate device is attached, which is fixedly mounted on the chassis. The alignment of the pump and the heating plate corresponds to the orientation of the lifting table, so that in the event that a container or a barrel with a product to be treated is arranged accordingly on your lifting table, the heating plate is moved into the container when the lifting table is moved up by the hydraulic cylinder or retract the barrel so that the product can be processed and pumped out.

An der erfindungsmäßen Faßhebevorrichtung ist weiterhin eine starre Leitung vorgesehen, die das aufbereitete und abgepumpte Produkt von der Pumpenanordnung zu einer weiteren Maschine oder zu einem Extruder leitet.A rigid line is also provided on the drum lifting device according to the invention, which conducts the processed and pumped-out product from the pump arrangement to another machine or to an extruder.

Diese Art voll Faßhebevorrichtung sichert auf vorteilhafte Art und Weise eine vollständige Abdeckung der bewegten Teile, da der Bewegungszylinder nicht zugänglich angeordnet ist, so daß keine ungeschützten und damit gefährlichen bewegten Teile vorhanden sind.This type of fully lifting device advantageously ensures complete coverage of the moving parts, since the movement cylinder is not arranged so that there are no unprotected and therefore dangerous moving parts.

Bei der erfindungsgemäßen Faßhebevorrichtung ist es auf überraschend einfache Art und Weise möglich, am selben Chassis eine zweite Faßhebevorrichtung in symmetrischer Anordnung zur ersten Faßhebeeinrichtung vorzusehen. Weiterhin ist es durch den Einsatz eines Hydraulikzylinders zum Heben und Absenken der Vorrichtung möglich, die Heizplatte aus dem Behälter oder dem Faß mit dem zu behandelnden Produkt zu extrahieren, ohne Druckluft zwischen die Heizplatte und das Produkt zu leiten. So wird auf vorteilhafte Art und Weise vermieden, daß es durch ein Restpolster von Druckluft zwischen Heizplatte und Produkt beim Verlassen der Heizplatte aus dein Behälter zu einem schlagartigen Entweichen der Druckluft kommen kann.In the drum lifting device according to the invention, it is possible in a surprisingly simple manner to provide a second drum lifting device in a symmetrical arrangement with the first drum lifting device on the same chassis. Furthermore, by using a hydraulic cylinder for lifting and lowering the device, it is possible to extract the heating plate from the container or the drum with the product to be treated, without passing compressed air between the heating plate and the product. This advantageously avoids that a residual cushion of compressed air between the heating plate and the product when the heating plate leaves the container can lead to a sudden escape of the compressed air.

Da anstelle von zwei Zylindern, wie im Stand der Technik, nur ein einziger Bewegungszylinder zum Anheben und Absenken des Hebetisches vorgesehen ist, reduziert sich auch der zum Betrieb der Vorrichtung notwendige Aufwand bezüglich der Leitungs- und Schaltanordnung. Da der Hebetisch über Halteelemente in Leitschienen an den vertikalen Stützelementen läuft, wird weiterhin auf vorteilhafte Art und Weise ein Verkanten und damit ein Hängenbleiben der Hebevorrichtung vermieden. Schließlich kann ein unkontrolliertes Absinken und Eintauchen der Heizplatte in das zu behandelnde Produkt durch eine Unterbrechung der Druckluftversorgung, wie im Stand der Technik, ausgeschlossen werden, da im schlimmsten Fall der Hebetisch mit dem Behälter absinken kann, was lediglich zu einer Extraktion der Heizplattenanordnung aus dein Behälter führt.Since instead of two cylinders, as in the prior art, only a single movement cylinder is provided for lifting and lowering the lifting table, the effort required for operating the device with regard to the line and switching arrangement is also reduced. Since the lifting table runs over holding elements in guide rails on the vertical support elements, tilting and thus jamming of the lifting device is further avoided in an advantageous manner. After all, an uncontrolled one Sinking and immersion of the heating plate in the product to be treated can be ruled out by interrupting the compressed air supply, as in the prior art, since in the worst case the lifting table with the container can sink, which only leads to an extraction of the heating plate arrangement from the container.

Durch das Vorsehen einer starren Ableitung von der Pumpenanordnung zu einer weiteren Maschine oder zu einem Extruder werden auf vorteilhafte Art und Weise die Nachteile des Standes der Technik bezüglich einer flexiblen Ableitung vermieden, die darin bestehen, daß durch die Dilatation der flexiblen Ableitung ein möglicherweise vorhandener Restdruck verloren geht.The provision of a rigid discharge from the pump arrangement to a further machine or to an extruder advantageously avoids the disadvantages of the prior art with regard to flexible discharge, which consist in that any residual pressure that may be present due to the dilation of the flexible discharge get lost.

Die erfindungsgemäße Faßhebevorrichtung stellt im Gegensatz zum Stand der Technik also eine erhebliche Verbesserung bezüglich der Sicherheit als auch der Effizienz bei Faßliebevorrichtungen mit Heiz-/Pumpenanordnungen dar.In contrast to the prior art, the drum lifting device according to the invention thus represents a considerable improvement with regard to safety and also efficiency in drum love devices with heating / pump arrangements.

Im folgenden wird unter Bezugnahme auf die einzige vorhandene Zeichnung ein bevorzugtes Ausführungsbeispiel der erfindungsgemäßen Faßhebevorrichtung beschrieben, darin zeigt:
