Description

Vorrichtung zum Befüllen flexibler SchüttgutbehalterDevice for filling flexible bulk containers
Die Erfindung betrifft eine Vorrrchtung flexidler Schüttgutbehälter.The invention relates to a device flexidler bulk container.
Bei üblichen Vorrichtungen zum Berüllen von Säcken und dergleichen, die ein Wiegen der eingefüllten Schüt tgutmenge vorsehen, ist die Waage entweder auf dem Boden aufgestellt oder in den Boden eingelassen. Im ersten Fall wird wegen der Bauhöhe der Waage zum Abnehmen des auf dieser stehenden schweren gefüllten Schüttgutbehältes im allgemeinen ein teurer Gabelstapler benötigt. Im zweiten Fall ist wegen der Fugen, die durch die in den Boden eingelassene Waage entstehen, eine Reinigung der Befüllvorrichtung und des umliegenden Bodens erschwert, was insbesondere dann unerwünscht ist, wenn unter hygienisch einwandfreien Bedingungen gearbeitet werden muß. Aufgabe der Erfindung ist es, hier Abhilfe zu schaffen und eine Befüllvorrichtung für flexible Schüttgutbehälter vorzusehen, von der der Schüttgutbehälter nach dem Befüllen mit einfachen Mitteln, beispielsweise einem Handwagen, abgenommen werden kann, ohne daß eine im Boden versenkte Waage vorgesehen ist.In conventional devices for filling bags and the like, which provide for weighing the filled amount of bulk material, the scale is either set up on the floor or embedded in the floor. In the first case, because of the height of the scales, an expensive forklift is generally required to remove the heavy filled bulk container standing on it. In the second case, cleaning of the filling device and the surrounding floor is made more difficult because of the joints caused by the scales embedded in the floor, which is particularly undesirable if work has to be carried out under hygienically perfect conditions. The object of the invention is to remedy this situation and to provide a filling device for flexible bulk containers, from which the bulk container can be removed after filling with simple means, for example a handcart, without a scales sunk in the floor is provided.
Hierzu schlägt die Erfindung eine Vorrichtung zum Befüllen flexibler Schüttgutbehälter vor, welche eine im oberen Bereich eines Standgestells oder an einem Hängegestell montierte Waage, an der Lastaufnahme der Waage hängende obere Trägermittel zum Anhängen eines flexiblen Schüttgutbehälters in einem oberen Bereich desselben, an der Lastaufnahme der Waage hängende untere Trägermittel zum Abstützen des flexiblen Schüttgutbehälters von unten, eine an der Lastaufnahme der Waage angebrachte Hubvorrichtung für die oberen und unteren Trägermittel zum Bewegen derselben zwischen einer Stellung, in der die unteren Trägermittel den Boden berühren, und einer Stellung, in der die unteren Trägermittel vom Boden abgehoben sind, und ein an der Lastaufnahme der Waage angebrachtes Füllrohr zum Befüllen des flexiblen Schüttgutbehälters von oben aufweist.To this end, the invention proposes a device for filling flexible bulk goods containers, which has an upper support means for hanging a flexible bulk goods container in an upper area of the same, attached to the load receptacle of the scales, mounted in the upper area of a stand frame or on a hanging frame hanging lower support means for supporting the flexible bulk goods container from below, a lifting device for the upper and lower support means attached to the load carrier of the balance for moving the same between a position in which the lower support means touch the ground and a position in which the lower support means are lifted off the floor and have a filling tube attached to the load receiver of the scale for filling the flexible bulk material container from above.
Zum Befüllen werden mittels der Hubvorrichtung die oberen und unteren Trägermittel mit dem daran hängenden bzw. darauf abgestützten Schüttgutbehälter so weit angehoben, daß auch die unteren Trägermittel nich t mehr auf dem Boden aufstehen . In diesem Hängezustand wird der Schüttgutbehälter durch das Füllrohr, an dem der Schüttgutbehälter mit seiner Füllöffnung bzw. seinem Füllstutzen befestigt ist, befüllt und die Füllmenge mittels der Waage gemessen, Nach dem Befüllen werden die oberen und unteren Trägermittel mittels der Hubvorrichtung wieder abgesenkt, bis die unteren Trägermittel auf dem Boden aufstehen, wonach der gefüllte Schüttgutbehälter wegen der möglichen niedrigen Bauhöhe der unteren Trägermittel mittels eines einfachen Handwagens von der Befüllvorrichtung abgenommen werden kann. Da während des Befüllens der Schüttgutbehälter durch die unteren Trägermittel von unten abgestützt war, wurde ein Ausbauchen des Schüttgutbehälters nach unten beim Befüllen vermieden, so daß der Schüttgutbehälter nach Abnahme von der Befüllvorrichtung auch von alleine steht. Nach einer bevorzugten Ausgestaltung der Erfindung weist die Befüllvorrichtung ferner ein vom Füllrohr durchsetztes längenveränderliches rohrartiges Element auf, welches im Bereich seines waagenseitigen Endes am Füllrohr befestigt und im Bereich seines schuttgutbehälterseitigen Endes an den oberen Trägermitteln befestigt und an den zu füllenden Schüttgutbehälter anschließbar ist.For filling, the upper and lower carrier means with the suspended or supported bulk container are raised so far by means of the lifting device that the lower carrier means no longer stand on the ground. In this hanging state, the bulk container is filled through the filling pipe to which the bulk container with its filling opening or its filler neck is attached, and the filling quantity is measured by means of the scales.After filling, the upper and lower carrier means are lowered again using the lifting device until the stand the lower carrier means on the floor, after which the filled bulk container can be removed from the filling device by means of a simple handcart due to the possible low overall height of the lower carrier means. Because during filling the bulk container the lower carrier means was supported from below, bulging of the bulk container downward during filling was avoided, so that the bulk container also stands by itself after removal from the filling device. According to a preferred embodiment of the invention, the filling device furthermore has a tube-like element, variable in length and penetrated by the filling tube, which is fastened to the filling tube in the region of its end on the balance side and fastened to the upper carrier means in the region of its end on the side of the bulk material container and can be connected to the bulk material container to be filled.
Hierdurch wird erreicht, daß der Anschluß der Befüllöffnung bzw. des Füllstutzens des Schüttgutbehälters an die Befüllvorrichtung immer und das Lösen von dieser nach dem Befüllen oftmals in normaler Greifhöhe, ohne das Vorsehen einer besonderen Bühne, durch hinreichendes Absenken der oberen Trägermittel mittels der Hubvorrichtung durchgeführt werden kann. Dies gilt hinsichtlich des Lösens selbst übermannshoher flexibler Schüttgutbehälter deshalb, weil diese bei einem hinreichenden Absenken der oberen Trägermittel mittels der Hubvorrichtung teilweise in sich zusammensinken bzw. sich im oberen Bereich niederdrücken lassen, da das Füllrohr, das mit seinem unteren Ende die maximale Füllhöhe bestimmt, immer mit einer gewissen Länge in das Behälterinnere hineinragt, so daß der Schüttgutbehälter oberhalb des Füllrohrendes leer bleibt.This ensures that the connection of the filling opening or the filler neck of the bulk container to the filling device always and the release of this after filling is often carried out at normal gripping height, without the provision of a special platform, by sufficient lowering of the upper carrier means by means of the lifting device can. This applies to the loosening of even taller flexible bulk containers because, when the upper carrier means are lowered sufficiently by the lifting device, they partially collapse or can be depressed in the upper area, since the filling tube, which determines the maximum filling height with its lower end, always protrudes with a certain length into the interior of the container so that the bulk container above the end of the filling tube remains empty.
Zur Anpassung an verschiedene Ausbildungen bzw. Längen des Füllstutzens des flexiblen Schüttgutbehälters ist gemäß einer bevorzugten Ausgestaltung der Erfindung vorgesehen, daß die Befestigung des längenveränderlichen rohrartigen Elements an den oberen Trägermitteln mit vertikaler Justierbarkeit des schuttgutbehälterseitigen Endes des rohrartigen Elements bezüglich der oberen Trägermittel gegeben ist. Gemäß, einer weiteren bevorzugten Ausgestaltung der Erfingung umfaßt das längenveränderliche rohrartige Element einen Faltenbalg. Dieser vereint auf einfache Weise die Längenveränderlichkeit mit einer Staubdichtigkeit.In order to adapt to different designs or lengths of the filler neck of the flexible bulk material container, it is provided according to a preferred embodiment of the invention that the length-adjustable tubular element is attached to the upper carrier means with vertical adjustability of the end of the tubular element on the bulk material container side with respect to the upper carrier means. According to a further preferred embodiment of the invention, the variable-length tubular element comprises a bellows. This combines length variability with dust tightness in a simple way.
Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist zwischen dem Füllrohr und dem dieses umgebenden rohrartigen Element ein Ringraum vorhanden, in welchem ein das rohrartige Element durchsetzender Entlüftungsstutzen mündet. Durch diesen Entlüftungsstutzen kann die vom Schüttgut verdrängte Luft aus dem Schüttgutbehälter entweichen. Bei geeignetem Anschluß des Entlüftungsstutzens, etwa an einen Absaugventilator mit Entstaubungsfilter ist auf dieseAccording to a further preferred embodiment of the invention, an annular space is present between the filling tube and the tube-like element surrounding it, in which an air vent connecting through the tube-like element opens. The air displaced by the bulk material can escape from the bulk material container through this vent. With a suitable connection of the ventilation socket, for example to a suction fan with dust filter, this is on
Weise gleichzeitig sichergestellt, daß mit der entweichenden Luft mitgeführtes Schüttgut zu keiner Verschmutzung der Umgebung der Befüllvorrichtung führt. Im folgenden wird eine bevorzugte Ausführungsform der Erfindung anhand der beigefügten Zeichnung beschrieben. Auf dieser zeigtWay at the same time ensured that bulk material carried with the escaping air does not lead to contamination of the surroundings of the filling device. A preferred embodiment of the invention is described below with reference to the accompanying drawing. On this shows
Fig. 1 die Vorrichtung in einem Zustand während der Befüllüng des Schüttgutbehälters, undFig. 1 shows the device in a state during the filling of the bulk container, and
Fig. 2 die Vorrichtung in einer Stellung zur Abnhame eines gefüllten oder zur Anbringung eines zu füllenden Schüttgutbehälters.Fig. 2 shows the device in a position for removing a filled or for attaching a bulk container to be filled.
Gemäß den Figuren 1 und 2 weist die Vorrichtung zum Befüllen flexibler Schüttgutbehälter eine auf einem auf dem Fußboden stehenden Gestell 20 oben angebrachte Waage 1 mit einem Kreiszeigerkopf 24 zur Gewichtsanzeige auf, auf deren Lastaufnahme bzw. Lastträgerteil 2 eine elektrische Hubvorrichtung 3 aufgebaut ist. An der Hubvorrichtung hängt an Drahtseilen 4 ein oberer Tragrahmen 5, an dem über weitere Drahtseile oder Ketten 6 ein unterer Tragrahmen 7 hängt.According to FIGS. 1 and 2, the device for filling flexible bulk material containers has a scale 1 mounted on a frame 20 standing on the floor at the top with a circular pointer head 24 for weight display, on the load holder or load carrier part 2 of which an electrical lifting device 3 is constructed. On the lifting device, an upper support frame 5 is attached to wire ropes 4, on which a lower support frame 7 is suspended via further wire ropes or chains 6.
Ein einen Einfüllstutzen 9 aufweisender Schüttgutbehälter 8 ist in seinem oberen Bereich mit Hilfe von SchlaufenA bulk container 8 having a filler neck 9 is in its upper region with the help of loops
10 am oberen Tragrahmen 5 an dort vorgesehenen Haken 22 eingehängt, und liegt mit seinem Boden direkt, oder indirekt über eine Palette 11, auf dem unteren Tragrahmen 7 auf.10 hung on the upper support frame 5 on the hooks 22 provided there, and lies with its bottom directly or indirectly via a pallet 11, on the lower support frame 7.
Am Lastträgerteil 2 der Waage 3 ist ferner, etwa zentral zu den beiden Tragrahmen ein vertikales Füllrohr 12 angebracht, durch das das Schüttgut etwa aus einem Vorratsbehälter in den flexiblen Schüttgutbehälter eingefüllt wird und das zur Anpassung an verschiedene Behältergrößen oder Füllstutzenmaße höhenverstellbar ist. In einem mittleren Bereich des Füllrohres 12 ist über einen Ring 13 ein das Füllrohr umgebender Faltenbalg 14 mit seinem oberen Ende staubdicht am Füllrohr befestigt, zum Beispiel angeschweißt. Am unteren Ende des Faltenbalgs befindet sich ein Rohrstutzen 15, an dem der Füllstutzen 9 des Schüttgutbehälters 8 beispielsweise mit Hilfe einer Schnellsackklemme 16 befestigbar ist.On the load carrier part 2 of the scale 3, a vertical filling tube 12 is also attached, approximately centrally to the two support frames, through which the bulk material is filled, for example from a storage container, into the flexible bulk material container and which is height-adjustable to adapt to different container sizes or filler neck dimensions. In a central area of the filler tube 12, a bellows 14 surrounding the filler tube is fastened with its upper end to the filler tube in a dustproof manner, for example welded on. At the lower end of the bellows there is a pipe socket 15, to which the filler socket 9 of the bulk material container 8 can be fastened, for example with the aid of a quick bag clamp 16.
Der obere Tragrahmen 5 weist ein Aufnahmekonstruktion 17 für den Rohrstutzen 15 des Faltenbalgs 14 auf, über die der Rohrstutzen 15 mit dem oberen Tragrahmen 5 verbunden ist. Ein Absenken und Anheben des oberen Tragrahmens 5 bewirkt dann ein Ausdehnen bzw. Zusammenschieben des Faltenbalgs 14. Die Aufnahmekonstruktion 17 für den Rohrstutzen 15 ist zur Anpassung an verschiedene Füllstutzenmaße des Schüttgutbehälters bezüglich des oberen Tragrahmens 5 höhenverstellbar. Im Ring 13 ist ein Entlüftungsrohrstutzen 18 vorgesehen, der in einen zwischen dem Füllrohr 12 und dem Faltenbalg 14 vorhandenen Ringraum mündet und über den während des Befüllvorgangs eine Abfuhr der aus dem Schüttgutbehälter durch das Schüttgut verdrängten Luft möglich ist. Bei Anschluß des Entlüftungsrohrstutzens, etwa über einen Schlauch, an einen Absaugventilator mit Staubfilter ist auf diese Weise auch für ein staubfreies Arbeiten ohne Verschmutzung der Umgebung der Befüllstation gesorgt.The upper support frame 5 has a receiving structure 17 for the pipe socket 15 of the bellows 14, via which the pipe socket 15 is connected to the upper support frame 5. A lowering and lifting of the upper support frame 5 then causes the bellows 14 to expand or collapse. The receiving structure 17 for the pipe socket 15 is height-adjustable with respect to the upper support frame 5 in order to adapt to different filler neck dimensions of the bulk material container. In the ring 13, a vent pipe socket 18 is provided, which opens into an annular space between the filling pipe 12 and the bellows 14 and via which a removal of the air displaced from the bulk material container by the bulk material is possible during the filling process. When the ventilation pipe socket is connected, for example via a hose, to a suction fan with a dust filter, this also ensures dust-free working without contamination of the surroundings of the filling station.
In dem in Fig. 1 gezeigten Befüll- und Wiegezustand der Vorrichtung sind die beiden Tragrahmen 5 und 7 durch die elektrische Hubvorrichtung, welche durch eine durch einen Elektromotor betriebene Seilwinde gebildet ist, vermittels der Drahtseile 4 und der Drahtseile bzw. Ketten 6 so weit angehoben, daß auch der untere Tragrahmen 7 frei hängt. Die Länge der Drahtseile bzw. Ketten 6 ist veränderbar, und durch eine entsprechende Anpassung dieser Länge ist erreicht, daß im angehobenen Zustand der am oberen Tragrahmen 5 angehängte Behälter in efoagestreckt am unteren Tragrahmen 7 unmittelbar oder mittelbar über die Palette 11 aufruht.In the filling and weighing state of the device shown in FIG. 1, the two support frames 5 and 7 are raised so far by means of the wire cables 4 and the wire cables or chains 6 by the electrical lifting device, which is formed by a cable winch operated by an electric motor that the lower support frame 7 hangs freely. The length of the wire ropes or chains 6 can be changed, and a corresponding adjustment of this length ensures that in the raised state the container attached to the upper support frame 5 is directly or indirectly rested on the lower support frame 7 in the stretched state via the pallet 11.
In der in Fig. 2 gezeigten Behälterwechselstellung vor bzw. nach dem Befüllen des flexiblen Schüttgutbehälters sind mit Hilfe der Hubvorrichtung 3 die Tragrahmen 5 und 7 abgesenkt, wobei der untere Tragrahmen 7 auf dem Boden aufliegt und der obere Tragrahmen 5 unter Streckung des Faltenbalgs 14 so tief liegt, daß die Befestigungsstelle des Schüttgutbehälters 8 am Rohrstutzen 15 bequem vom Boden aus erreichbar ist. In dieser Stellung sind beim Abnehmen eines gefüllten Schüttgutbehälters die Schlaufen 10 auch zugentlastet, so daß sie ohne Schwierigkeiten von den Haken 22 des oberen Tragrahmens 7 gelöst werden können und der Behälter beispielsweise mit Hilfe eines einfachen Sackwagens vom flachen unteren Tragrahmen 7 abtransportiert werden kann.In the container change position shown in FIG. 2 before or after filling the flexible bulk material container, the support frames 5 and 7 are lowered with the aid of the lifting device 3, the lower support frame 7 resting on the floor and the upper support frame 5 stretching the bellows 14 in this way is low that the attachment point of the bulk container 8 on the pipe socket 15 is easily accessible from the ground. In this position, the loops 10 are also relieved of strain when removing a filled bulk goods container, so that they can be easily detached from the hooks 22 of the upper support frame 7 and the container can be removed from the flat lower support frame 7, for example with the aid of a simple sack trolley.
Bei einer Ausführungsform der Befüllvorrichtung ohne Faitenbalg bzw. längenveränderliches rohrartiges Element wird der Füllstutzen 9 des Schüttgutbehälters 8 etwa mittels einer Schnellsackklemme 16 direkt am Füllrohr 12 befestigt. Dies bedeutet, daß eine Bedienungsperson, unter Umständen unter Zuhilfenahme einer Bühne, den Füllstutzen 9 erst vom Füllrohr 12 lösen muß, bevor ein gefüllter Schüttgutbehälter 8 mittels derIn one embodiment of the filling device without bellows or tube-like element variable in length, the filler neck 9 of the bulk material container 8 is fastened directly to the filling tube 12 by means of a quick-sack clamp 16. This means that an operator, possibly with the aid of a platform, must first remove the filler neck 9 from the filler pipe 12 before a filled bulk goods container 8 can be opened by means of the
Hubvorrichtung 3 abgesenkt werden kann. Ebenso muß auch ein zu befüllender leerer Schüttgutbehälter bereits in der Höhe am Füllrohr 12 angebracht werden, in der sich die Befestigungsstelle während des Befüllvorgangs befinden soll. Lifting device 3 can be lowered. Likewise, an empty bulk container to be filled must also be attached to the filling pipe 12 at the height at which the fastening point is to be located during the filling process.
