Definitions

  • the invention relates to a closable filling device for filling bulk goods from flexible bulk goods containers, in particular a filling mandrel.
  • a flexible bulk goods container is a large sack made of fabric or plastic fabric, which is known as a big bag. In order to completely empty the bigbag quickly, it is usually lifted and the bottom surface cut open with a knife. In order to be able to dose the emptying, filling devices in the form of a mandrel are known, which are pierced with their point first into the plastic fabric from below so that they penetrate as far as the bulk material. The bulk material can be emptied from the flexible bulk material container through openings in the filling device, the filling device having a closure mechanism in order to be able to start and stop the emptying.
  • the DE602004001709T2 shows a gate valve which is present between two rigid disk-shaped elements. At least one of the disk-shaped elements is to be attached to a rigid container. The gate valve cannot form a standing surface for the device, since it is enclosed between the rigidly connected disk-shaped elements.
  • the DE102006057760B3 discloses a linear connector and liner filler that does not have a gate valve.
  • the FR2895728A3 shows a filling device in the form of a filling mandrel for big bags.
  • the filling mandrel has a cylindrical hollow body, at the upper end of which several struts converge to form a point. At a distance from the struts, the filling mandrel has barbs which protrude from the cylindrical hollow body.
  • the cylindrical hollow body has openings above the barbs.
  • the cylindrical hollow body has a closure, which is formed from two adjacent plates, the upper plate being firmly connected to the cylindrical hollow body and having a central opening and the lower plate being designed over the entire surface and pivotable on the upper one with a threaded bolt Plate is attached.
  • the tip of the filling spike is inserted into the big bag until the barbs penetrate the big bag. Then the filling mandrel is pulled back a little so that the barbs rest against the fabric of the big bag from the inside. Bulk material can now penetrate into the cylindrical hollow body between the struts and through the openings above the barbs.
  • the closure is opened by pivoting the lower plate around the threaded bolt and the bulk material passes down through the cylindrical hollow body. Both plates are provided with handles so that the swivel movement can be carried out by hand.
  • the disadvantage is the mounting of the lower plate on the threaded bolt, since the nut or the head of the threaded bolt protrudes from the lower plate and thus the filling mandrel is not level on the ground.
  • the EP 2937291 A1 shows an extension of the device of FIG FR 2895728 A3 around a filling spout, which, if necessary, can be screwed onto the upper plate from below when the filling mandrel is already inserted. Otherwise, the devices are identical, with neither the filling mandrel nor the filling spout having a satisfactory footprint.
  • the above-mentioned devices are used by placing them with the lower plate of the closure on the floor and lowering the flexible bulk material container or big bag from above onto the filling mandrel.
  • the protruding bolt does not provide a level stand.
  • great forces act on the filling mandrel, which can lead to one of the handles, usually the one on the top plate, breaking off.
  • the lower plate can be pushed downwards away from the upper plate, so that bulk material can unintentionally escape or unfavorably high moments act on the bolt and the lower plate, which can lead to damage can.
  • the object on which the invention is based is to improve filling devices for flexible bulk material containers so that the damage mentioned is avoided.
  • a preferred improvement measure according to the invention consists in attaching at least one of the handles to the respective plate so that it can pivot, so that it can be folded away upwards. If too great a moment acts on the handle when the flexible bulk goods container is placed on, it will fold up before damage can occur.
  • the upper plate preferably has an at least approximately square circumference, with the lower plate in the closed state of the filling device covering at least the lower opening area of the upper plate and the corner areas of the at least approximately square circumference and the lower plate being provided with the structure at least in these corner areas , which forms the base and / or four legs of the filling device.
  • the lower plate and the upper plate of the filling device with a structure so that both plates form a common lower surface on which the filling device stands, with the head or the nut of the bolt of the pivoting mechanism not over this common lower surface the upper and lower plate protrudes and the upper plate or its handle at a distance from the contact surface with the lower plate has at least one locking projection, the lower plate being held in the closed state between this locking projection and the contact surface.
  • At least two locking projections are preferably present which hold the lower plate on the upper plate in the closed state. These locking projections preferably have an angle of at least 90 ° to 135 ° to each other and to the bolt (e.g. an angle of 120 ° or 90 ° and 135 ° twice), based on the center of the opening of the hollow body, so that the lower plate is held in the closed position at three spaced points distributed around the circumference of the opening.
  • a handle is attached to each of the upper plate and lower plate, each of which extends approximately horizontally away from the respective plate, the lower surface of the respective handle not protruding downward beyond the standing surface of the filling device.
  • the measure according to the invention to fasten at least one of the levers or handles pivotably on the respective plate so that it can be folded away upwards can also be implemented independently of the other improvements according to the invention, so that the filling device known from the prior art only has at least one Folding handles is improved.

  • the hollow body 2 has barbs 9 on the outside, which are made of elastic material, so that these are pressed downwards against the hollow body 2 when piercing through the tissue of the big bag so as not to block the opening in the tissue enlarge. If the barbs 9 are moved completely through the tissue, they return to their starting position and spread when they are pulled back against the inside of the tissue. A little above the barbs 9 there are openings 10 in the lateral surface of the hollow body 2 in order to enable the big bag to be emptied almost completely. Alternatively, it would also be possible to attach the barbs 9 further up on the hollow body 2 in order to be able to dispense with the openings 10, as in the alternative embodiment of FIG Fig. 5 is illustrated.
  • the barbs 9, known from the prior art, are in the form of strips of resilient elastic material and are guided inward through slots in the hollow body 2 and fastened above the slots on the inside of the hollow body 2 by rivets.

Ein flexibler Schüttgutbehälter ist ein großer Sack aus Stoff- oder Kunststoffgewebe, welcher unter der Bezeichnung Bigbag bekannt ist. Um den Bigbag schnell vollständig zu entleeren, wird dieser meist angehoben und dessen Bodenfläche mit einem Messer aufgeschnitten. Um die Entleerung dosieren zu können, sind Abfüllvorrichtungen in Form eines Dorns bekannt, welche mit ihrer Spitze voran von unten in das Kunststoffgewebe eingestochen werden, sodass diese bis zum Schüttgut eindringen. Das Schüttgut kann durch Öffnungen in der Abfüllvorrichtung aus dem flexiblen Schüttgutbehälter entleert werden, wobei die Abfüllvorrichtung einen Verschlussmechanismus aufweist, um die Entleerung starten und stoppen zu können.A flexible bulk goods container is a large sack made of fabric or plastic fabric, which is known as a big bag. In order to completely empty the bigbag quickly, it is usually lifted and the bottom surface cut open with a knife. In order to be able to dose the emptying, filling devices in the form of a mandrel are known, which are pierced with their point first into the plastic fabric from below so that they penetrate as far as the bulk material. The bulk material can be emptied from the flexible bulk material container through openings in the filling device, the filling device having a closure mechanism in order to be able to start and stop the emptying.

Die DE602004001709T2 zeigt einen Absperrschieber, welcher zwischen zwei starren scheibenförmigen Elementen vorliegt. Zumindest eines der scheibenförmigen Elemente ist an einem starren Behälter zu befestigen. Der Absperrschieber kann keine Standfläche der Vorrichtung bilden, da dieser zwischen den starr verbundenen scheibenförmigen Elementen eingeschlossen ist.The DE602004001709T2 shows a gate valve which is present between two rigid disk-shaped elements. At least one of the disk-shaped elements is to be attached to a rigid container. The gate valve cannot form a standing surface for the device, since it is enclosed between the rigidly connected disk-shaped elements.

Die DE102006057760B3 offenbart eine Linearanschlussvorrichtung und Linerbefüllvorrichtung, welche keinen Absperrschieber aufweist.The DE102006057760B3 discloses a linear connector and liner filler that does not have a gate valve.

Die FR2895728A3 zeigt eine Abfüllvorrichtung in Form eines Abfülldorns für Bigbags. Der Abfülldorn hat einen zylindrischen Hohlkörper, an dessen oberen Ende mehrere Streben zu einer Spitze zusammenlaufen. Beabstandet zu den Streben weist der Abfülldorn Widerhaken auf, welche vom zylindrischen Hohlkörper abstehen. Oberhalb der Widerhaken weist der zylindrische Hohlkörper Öffnungen auf. Am unteren Ende weist der zylindrische Hohlkörper einen Verschluss auf, welcher aus zwei aneinanderliegenden Platten gebildet ist, wobei die obere Platte fest mit dem zylindrischen Hohlkörper verbunden ist und eine zentrale Öffnung aufweist und die untere Platte vollflächig ausgeführt ist und mit einem Gewindebolzen schwenkbar an der oberen Platte befestigt ist. Der Abfülldorn wird mit der Spitze in den Bigbag eingestochen, bis die Widerhaken in den Bigbag eindringen. Dann wird der Abfülldorn etwas zurückgezogen, sodass die Widerhaken von innen am Gewebe des Bigbag anliegen. Schüttgut kann nun zwischen den Streben und durch die Öffnungen oberhalb der Widerhaken in den zylindrischen Hohlkörper eindringen. Durch Schwenken der unteren Platte um den Gewindebolzen wird der Verschluss geöffnet und das Schüttgut gelangt durch den zylindrischen Hohlkörper nach unten. Beide Platten sind mit Griffen versehen, um die Schwenkbewegung per Hand ausführen zu können. Nachteilig ist die Lagerung der unteren Platte am Gewindebolzen, da die Mutter bzw. der Kopf des Gewindebolzens unten von der unteren Platte vorsteht und somit der Abfülldorn nicht eben am Boden steht. Zudem nachteilig ist, dass bei geschlossenem Verschluss die untere Platte nur am Gewindebolzen gehalten ist und somit die Gewichtskraft des Schüttguts auf die Platte ein starkes Moment ausübt, wodurch das dem Gewindebolzen gegenüberliegende Ende der Platte nach unten gedrückt wird, was eine erhebliche Belastung oder gar Verformung der unteren Platte ergibt. Beziehungsweise sind die bekannten Verschlüsse aufgrund der unzulänglichen Abstützung bei feinem Schüttgut wie Sand oder Salz nicht ausreichend dicht.The FR2895728A3 shows a filling device in the form of a filling mandrel for big bags. The filling mandrel has a cylindrical hollow body, at the upper end of which several struts converge to form a point. At a distance from the struts, the filling mandrel has barbs which protrude from the cylindrical hollow body. The cylindrical hollow body has openings above the barbs. At the lower end, the cylindrical hollow body has a closure, which is formed from two adjacent plates, the upper plate being firmly connected to the cylindrical hollow body and having a central opening and the lower plate being designed over the entire surface and pivotable on the upper one with a threaded bolt Plate is attached. The tip of the filling spike is inserted into the big bag until the barbs penetrate the big bag. Then the filling mandrel is pulled back a little so that the barbs rest against the fabric of the big bag from the inside. Bulk material can now penetrate into the cylindrical hollow body between the struts and through the openings above the barbs. The closure is opened by pivoting the lower plate around the threaded bolt and the bulk material passes down through the cylindrical hollow body. Both plates are provided with handles so that the swivel movement can be carried out by hand. The disadvantage is the mounting of the lower plate on the threaded bolt, since the nut or the head of the threaded bolt protrudes from the lower plate and thus the filling mandrel is not level on the ground. Another disadvantage is that when the closure is closed, the lower plate is only held on the threaded bolt and thus the weight of the bulk material is applied to the plate exerts a strong moment, whereby the end of the plate opposite the threaded bolt is pressed downwards, which results in a considerable load or even deformation of the lower plate. Or the known closures are not sufficiently tight due to the inadequate support for fine bulk material such as sand or salt.

Die EP 2937291 A1 zeigt eine Erweiterung der Vorrichtung der FR 2895728 A3 um einen Füllstutzen, welcher bei Bedarf bei bereits eingestochenem Abfülldorn von unten an die obere Platte geschraubt werden kann. Ansonsten sind die Vorrichtungen ident, wobei weder der Abfülldorn noch der Füllstutzen eine zufriedenstellende Standfläche aufweisen.The EP 2937291 A1 shows an extension of the device of FIG FR 2895728 A3 around a filling spout, which, if necessary, can be screwed onto the upper plate from below when the filling mandrel is already inserted. Otherwise, the devices are identical, with neither the filling mandrel nor the filling spout having a satisfactory footprint.

In der Praxis werden die oben genannten Vorrichtungen verwendet, indem diese mit der unteren Platte des Verschlusses auf den Boden gestellt werden und der flexible Schüttgutbehälter bzw. Bigbag von oben auf den Abfülldorn heruntergesenkt wird. Durch den überstehenden Bolzen ist kein ebener Stand gegeben. Beim Herabsenken des Bigbags wirken große Kräfte auf den Abfülldorn, was dazu führen kann, dass einer der Griffe, meist jener der oberen Platte abbricht. Zudem besteht das Problem, dass bei Anheben des Bigbags samt Dorn die untere Platte nach unten von der oberen Platte weggedrückt werden kann, sodass Schüttgut ungewollt entweichen kann, bzw. ungünstig hohe Momente auf den Bolzen und die untere Platte wirken, was zu einer Beschädigung führen kann. Zudem werden volle oder teilentleerte flexible Schüttgutbehälter bzw. Bigbags oft mit noch eingesetzten Abfüllvorrichtungen am Boden abgestellt, wobei die bekannten Abfüllvorrichtungen nur mäßig dafür geeignet sind und wodurch vermehrt Beschädigungen auftreten können. Dies ist auch bei bekannten Abfüllvorrichtungen von Mehrweg-Bigbags bzw. flexiblen Mehrweg-Schüttgutbehälter der Fall.In practice, the above-mentioned devices are used by placing them with the lower plate of the closure on the floor and lowering the flexible bulk material container or big bag from above onto the filling mandrel. The protruding bolt does not provide a level stand. When the big bag is lowered, great forces act on the filling mandrel, which can lead to one of the handles, usually the one on the top plate, breaking off. In addition, there is the problem that when the big bag and the mandrel are lifted, the lower plate can be pushed downwards away from the upper plate, so that bulk material can unintentionally escape or unfavorably high moments act on the bolt and the lower plate, which can lead to damage can. In addition, full or partially emptied flexible bulk goods containers or big bags are often parked on the floor with filling devices still in use, the known filling devices being only moderately suitable for this and which can lead to increased damage. This is also the case with known filling devices for reusable big bags or flexible reusable bulk goods containers.

Die der Erfindung zu Grunde liegende Aufgabe besteht darin, Abfüllvorrichtungen für flexible Schüttgutbehälter zu verbessern, sodass die genannten Schäden vermieden werden.The object on which the invention is based is to improve filling devices for flexible bulk material containers so that the damage mentioned is avoided.

Zum Lösen der Aufgabe wird eine Abfüllvorrichtung gemäß Anspruch 1 vorgeschlagen.To achieve the object, a filling device according to claim 1 is proposed.

Eine bevorzugte erfindungsgemäße Verbesserungsmaßnahme besteht darin, zumindest einen der Griffe schwenkbar an der jeweiligen Platte zu befestigen, sodass dieser nach oben hin wegklappbar ist. Sollte beim Aufsetzen des flexiblen Schüttgutbehälters ein zu großes Moment auf den Griff wirken, klappt dieser nach oben, bevor es zu einer Beschädigung kommen kann. Bevorzugt weist die obere Platte einen zumindest annähernd quadratischen Umfang auf, wobei die untere Platte im geschlossenen Zustand der Abfüllvorrichtung zumindest die untere Öffnungsfläche der oberen Platte und die Eckbereiche deren zumindest annähernd quadratischen Umfangs abdeckt und die untere Platte zumindest in diesen Eckbereichen mit der Struktur versehen ist, welche die Standfläche und/oder vier Standbeine der Abfüllvorrichtung bildet.A preferred improvement measure according to the invention consists in attaching at least one of the handles to the respective plate so that it can pivot, so that it can be folded away upwards. If too great a moment acts on the handle when the flexible bulk goods container is placed on, it will fold up before damage can occur. The upper plate preferably has an at least approximately square circumference, with the lower plate in the closed state of the filling device covering at least the lower opening area of the upper plate and the corner areas of the at least approximately square circumference and the lower plate being provided with the structure at least in these corner areas , which forms the base and / or four legs of the filling device.

Bevorzugt wird vorgeschlagen die untere Platte und die obere Platte der Abfüllvorrichtung mit einer Struktur zu versehen, sodass beide Platten eine gemeinsame untere Fläche bilden, auf welcher die Abfüllvorrichtung steht, wobei der Kopf bzw. die Mutter des Bolzens des Schwenkmechanismus nicht über diese gemeinsame untere Fläche der oberen und unteren Platte ragt und die obere Platte oder deren Griff beabstandet zur Berührungsfläche mit der unteren Platte zumindest einen Verriegelungsvorsprung aufweist, wobei die untere Platte im geschlossenen Zustand zwischen diesem Verriegelungsvorsprung und der Berührungsfläche gehalten ist.It is preferably proposed to provide the lower plate and the upper plate of the filling device with a structure so that both plates form a common lower surface on which the filling device stands, with the head or the nut of the bolt of the pivoting mechanism not over this common lower surface the upper and lower plate protrudes and the upper plate or its handle at a distance from the contact surface with the lower plate has at least one locking projection, the lower plate being held in the closed state between this locking projection and the contact surface.

Bevorzugt sind zumindest zwei Verriegelungsvorsprünge vorhanden, welche die untere Platte im geschlossenen Zustand an der oberen Platte halten. Bevorzugt weisen diese Verriegelungsvorsprünge zueinander und zum Bolzen einen Winkel von zumindest je 90° bis 135° auf (z.B. je ein Winkel von 120° oder einmal 90° und zweimal 135°), bezogen auf den Mittelpunkt der Öffnung des Hohlkörpers, sodass die untere Platte in geschlossener Position an drei beabstandeten, über den Umfang der Öffnung verteilten Punkten gehalten ist.At least two locking projections are preferably present which hold the lower plate on the upper plate in the closed state. These locking projections preferably have an angle of at least 90 ° to 135 ° to each other and to the bolt (e.g. an angle of 120 ° or 90 ° and 135 ° twice), based on the center of the opening of the hollow body, so that the lower plate is held in the closed position at three spaced points distributed around the circumference of the opening.

Erfindungsgemäß ist an der oberen Platte und unteren Platte jeweils ein Griff angebracht, welche sich jeweils in etwa horizontal von der jeweiligen Platte weg erstrecken, wobei die untere Fläche des jeweiligen Griffs nach unten hin nicht über die Standfläche der Abfüllvorrichtung ragt.According to the invention, a handle is attached to each of the upper plate and lower plate, each of which extends approximately horizontally away from the respective plate, the lower surface of the respective handle not protruding downward beyond the standing surface of the filling device.

Die erfindungsgemäße Maßnahme zumindest einen der Hebel bzw. Griffe schwenkbar an der jeweiligen Platte zu befestigen, sodass dieser nach oben hin wegklappbar ist, kann auch unabhängig von den anderen erfindungsgemäßen Verbesserungen umgesetzt werden, sodass die aus dem Stand der Technik bekannte Abfüllvorrichtung lediglich mit zumindest einem Klappgriffen verbessert wird. In diesem Fall kann natürlich die zuvor beschriebene erstgereihte erfindungsgemäße Lösung der verbesserten Standfläche zusätzlich vorgesehen werden, um die Abfüllvorrichtung weiter zu verbessern.The measure according to the invention to fasten at least one of the levers or handles pivotably on the respective plate so that it can be folded away upwards can also be implemented independently of the other improvements according to the invention, so that the filling device known from the prior art only has at least one Folding handles is improved. In this case, the above-described first-tier solution according to the invention of the improved standing area can of course also be provided in order to further improve the filling device.

Die Fig. 1 bis 4 zeigen alle denselben besonders bevorzugten erfindungsgemäßen Abfülldorn 1. Der Abfülldorn 1 weist einen Hohlkörper 2 auf, welcher bevorzugt einen zylindrischen Mantel aufweist. Am oberen Ende des Hohlkörpers 2 verlaufen mehrere Streben 3 zu einer Spitze zusammen. Aus Stabilitätsgründen und aufgrund der Fertigung im Kunststoff-Spritzgussverfahren haben sich vier gleichmäßig über den Umfang des Zylinders verteilte Streben 3 als technisch bedingt günstigste Variante herausgestellt, da drei Streben 3 eine sehr aufwendige Spritzgussform erforderlich machen würden. Am unteren Ende geht der Hohlkörper 2 in die obere Platte 4 über, welche außen an den Zylinder anschließt und die innere Öffnung des Hohlkörpers 2 bevorzugt zur Gänze offen lässt. Der Hohlkörper 2, die obere Platte 4 und die die Spitze bildenden Streben 3 werden bevorzugt als monolithischer Kunststoffkörper im Spritzgussverfahren gefertigt.The Figs. 1 to 4 all show the same particularly preferred filling mandrel 1 according to the invention. The filling mandrel 1 has a hollow body 2, which preferably has a cylindrical jacket. At the upper end of the hollow body 2, several struts 3 run to a point together. For reasons of stability and because of the production in the plastic injection molding process, four struts 3 evenly distributed over the circumference of the cylinder have proven to be the technically most favorable variant, since three struts 3 would require a very complex injection mold. At the lower end, the hollow body 2 merges into the upper plate 4, which connects to the outside of the cylinder and preferably leaves the inner opening of the hollow body 2 completely open. The hollow body 2, the upper plate 4 and the struts 3 forming the tip are preferably manufactured as a monolithic plastic body in an injection molding process.

Um die untere Öffnung des Hohlkörpers 2 bzw. der oberen Platte 4 verschließbar zu machen, ist eine schwenkbare untere Platte 5 vorgesehen. Die obere Platte 4 ist mit einem Griff 6 versehen und die untere Platte 5 ist mit einem Griff 7 versehen, welche im geschlossenen Zustand des Verschlusses bevorzugt diametral gegenüber liegen. Die obere Platte 4 und die untere Platte 5 weisen je eine Bohrung auf, durch welche der Bolzen 8 verläuft, wobei der Bolzen 8 in zumindest einer dieser Bohrungen schwenkbar gehalten ist. Die untere Platte 5 kann um die Achse des Bolzens 8 geschwenkt werden, um die Öffnung des Hohlkörpers 2 nach unten hin frei zu geben, wie in Fig. 3 zu erkennen ist.In order to make the lower opening of the hollow body 2 or the upper plate 4 closable, a pivotable lower plate 5 is provided. The upper plate 4 is provided with a handle 6 and the lower plate 5 is provided with a handle 7, which in the closed state of the closure are preferably diametrically opposite. The upper plate 4 and the lower plate 5 each have a bore through which the bolt 8 runs, the bolt 8 being held pivotably in at least one of these bores. The lower plate 5 can be pivoted about the axis of the bolt 8 in order to free the opening of the hollow body 2 downwards, as in FIG Fig. 3 can be seen.

Zwischen den Streben 3 und der oberen Platte 4 weist der Hohlkörper 2 außen Widerhaken 9 auf, welche aus elastischem Material bestehen, sodass diese beim Einstechen durch das Gewebe des Bigbags nach unten hin an den Hohlkörper 2 angedrückt werden, um die Öffnung im Gewebe nicht zu vergrößern. Werden die Widerhaken 9 vollständig durch das Gewebe bewegt, gehen diese in ihre Ausgangsposition zurück und spreizen sich beim Zurückziehen gegen die Innenseite des Gewebes. Etwas oberhalb der Widerhaken 9 sind Öffnungen 10 in der Mantelfläche des Hohlkörpers 2 vorhanden, um eine nahezu restlose Entleerung des Bigbags zu ermöglichen. Alternativ wäre es auch möglich, die Widerhaken 9 weiter oben am Hohlkörper 2 anzubringen, um auf die Öffnungen 10 verzichten zu können, wie in der alternativen Ausführungsvariante der Fig. 5 veranschaulicht ist. Die Widerhaken 9 liegen, nach dem Stand der Technik bekannt, als Streifen aus nachgiebigem elastischem Material vor und werden durch Schlitze im Hohlkörper 2 nach innen geführt und oberhalb der Schlitze an der Innenseite des Hohlkörpers 2 durch Nieten befestigt. Als Material eignet sich relativ fester Gummi. Erfindungsgemäß können gemäß Fig. 5 die Widerhaken 9 als Federstahlplättchen ausgeführt sein, welche einen Knick mit spitzem Winkel aufweisen und unterhalb der Schlitze an der Innenseite des Hohlkörpers 2 durch Nieten oder Schrauben befestigt sind, wodurch die Distanz zwischen den Widerhaken 9 zur oberen Öffnungsfläche des Hohlkörpers verringert werden kann, um die Vorrichtung einfacher, kleiner und somit materialsparend und kostengünstiger fertigen zu können.Between the struts 3 and the upper plate 4, the hollow body 2 has barbs 9 on the outside, which are made of elastic material, so that these are pressed downwards against the hollow body 2 when piercing through the tissue of the big bag so as not to block the opening in the tissue enlarge. If the barbs 9 are moved completely through the tissue, they return to their starting position and spread when they are pulled back against the inside of the tissue. A little above the barbs 9 there are openings 10 in the lateral surface of the hollow body 2 in order to enable the big bag to be emptied almost completely. Alternatively, it would also be possible to attach the barbs 9 further up on the hollow body 2 in order to be able to dispense with the openings 10, as in the alternative embodiment of FIG Fig. 5 is illustrated. The barbs 9, known from the prior art, are in the form of strips of resilient elastic material and are guided inward through slots in the hollow body 2 and fastened above the slots on the inside of the hollow body 2 by rivets. Relatively solid rubber is suitable as a material. According to the invention, according to Fig. 5 the barbs 9 are designed as spring steel plates, which have a kink with an acute angle and are attached below the slots on the inside of the hollow body 2 by rivets or screws, whereby the distance between the barbs 9 to the upper opening surface of the hollow body can be reduced to the Device easier to manufacture, smaller and thus material-saving and more cost-effective.

Die wesentliche erfindungsgemäße Verbesserung betrifft den Verschluss bzw. die Bodenfläche des Abfülldorns 1. Erfindungsgemäß ist vorgesehen, die obere Platte 4 mit einer Struktur 11 zu versehen, welche einen Teil der Standfläche des Abfülldorns 1 bildet. Ebenso ist erfindungsgemäß vorgesehen, die untere Platte 5 mit einer Struktur 12 zu versehen, welche ebenfalls einen Teil der Standfläche des Abfülldorns 1 bildet. Der Kopf des Bolzens 8 ragt maximal bis zur Standfläche vor und ist bevorzugt in einer Aussparung der Struktur 12 aufgenommen. Wie insbesondere in Fig. 3 gut zu erkennen ist, ist es ausreichend die Strukturen 11 und 12 als Stege am Rand der jeweiligen Platte 4, 5 auszuführen. Alternativ kann bei der unteren Platte 5 nahezu die gesamte Fläche mit der Struktur 12 versehen werden, mit Ausnahme der Aussparung für den Kopf des Bolzens 8 und je einer Aussparung für die Verriegelung pro Verriegelungsvorsprung 13. Die Struktur 11 ist so an der oberen Platte 4 angeordnet, dass diese die Schwenkbewegung der oberen Platte 4 nicht beeinträchtigt. Der Umfang der oberen Platte 4 ist dazu größer ausgeführt als jener der unteren Platte 5. Eine besonders gute Standfestigkeit ergibt sich, wenn die durch die Strukturen 11 und 12 gebildete Standfläche einen annähernd quadratischen Umfang aufweist. Die Unterseiten der Griffe 6, 7 können mit der Standfläche eine ebene Fläche bilden, also mit den Strukturen 11, 12 koplanar abschließen. Wie in der alternativen Ausgestaltung der Fig. 5 dargestellt, können die Unterseiten der Griffe 6, 7 auch nach oben hin beabstandet von der Standfläche sein.The essential improvement according to the invention relates to the closure or the bottom surface of the filling mandrel 1. According to the invention, the upper plate 4 is provided with a structure 11 which forms part of the standing surface of the filling mandrel 1. Likewise is According to the invention, it is provided that the lower plate 5 is provided with a structure 12 which also forms part of the standing surface of the filling mandrel 1. The head of the bolt 8 protrudes at most up to the standing surface and is preferably received in a recess in the structure 12. As in particular in Fig. 3 As can be clearly seen, it is sufficient to design the structures 11 and 12 as webs on the edge of the respective plate 4, 5. Alternatively, almost the entire surface of the lower plate 5 can be provided with the structure 12, with the exception of the recess for the head of the bolt 8 and one recess for the locking per locking projection 13. The structure 11 is thus arranged on the upper plate 4 that this does not affect the pivoting movement of the upper plate 4. For this purpose, the circumference of the upper plate 4 is made larger than that of the lower plate 5. A particularly good stability results when the standing surface formed by the structures 11 and 12 has an approximately square circumference. The undersides of the handles 6, 7 can form a flat surface with the standing surface, that is to say terminate coplanar with the structures 11, 12. As in the alternative embodiment of the Fig. 5 shown, the undersides of the handles 6, 7 can also be spaced upwards from the base.

Erfindungsgemäß weist der Verschluss einen Verriegelungsvorsprung 13 auf, welcher Teil der oberen Platte 4 ist, oder an dieser befestigt ist. Der Verriegelungsvorsprung 13 ist so angebracht, dass dieser bei geschlossenem Verschluss die unter Platte 5 gegen die obere Platte 4 hält. Der Verriegelungsvorsprung 13 weist dazu einen plattenförmigen Abschnitt auf, dessen obere Fläche beabstandet zur oberen Platte 4 vorliegt und dessen untere Fläche bevorzugt koplanar mit der Standfläche bzw. der Struktur 11 liegt. Beim Schließen gelangt die untere Platte 5 mit ihrem Randreich in den Spalt zwischen Verriegelungsvorsprung 13 und oberer Platte 4 und weist in diesem Randbereich bevorzugt eine Fase 16 oder Abrundung auf, um dies zu erleichtern. Der Verriegelungsvorsprung 13 liegt, auf die untere Öffnung des Hohlkörpers 2 bezogen, bevorzugt in etwa diametral gegenüber dem Bolzen 8. Für den Fall, dass die obere Platte 4 zwei Verriegelungsvorsprünge 13 aufweist, schließen diese, auf die untere Öffnung des Hohlkörpers 2 bezogen, bevorzugt zueinander und zum Bolzen 8 einen Winkel von je etwa 120° ein. In der dargestellten Ausführungsvariante der Fig. 1-4 ist ein Verriegelungsvorsprung 13 vorhanden, welcher einen Winkel von ca. 135° zum Bolzen 8 aufweist und einen Winkel von ca. 135° zum Griff 7 aufweist, da auch der Griff 7 bzw. die untere Platte 5 im Bereich des Griffes 7 einen Verriegelungsvorsprung 14 aufweist, welcher die obere Platte 4 im geschlossenen Zustand übergreift. Der Griff 7 weist zum Bolzen 8 einen Winkel von ca. 90° auf. Auf diesen Verriegelungsvorsprung 14 kann verzichtet werden, wenn in diesem Bereich, bzw. wie zuvor erwähnt im Winkel von 120° zum Bolzen 8 ein zweiter Verriegelungsvorsprung 13 an der oberen Platte 4 vorgesehen ist.According to the invention, the closure has a locking projection 13 which is part of the upper plate 4 or is attached to it. The locking projection 13 is attached so that it holds the lower plate 5 against the upper plate 4 when the lock is closed. For this purpose, the locking projection 13 has a plate-shaped section, the upper surface of which is at a distance from the upper plate 4 and the lower surface of which is preferably coplanar with the standing surface or the structure 11. When closing, the edge region of the lower plate 5 enters the gap between the locking projection 13 and the upper plate 4 and in this edge region preferably has a chamfer 16 or a rounded portion in order to facilitate this. The locking projection 13 is, with respect to the lower opening of the hollow body 2, preferably approximately diametrically opposite the bolt 8. In the event that the upper plate 4 has two locking projections 13, these preferably close with respect to the lower opening of the hollow body 2 to each other and to the bolt 8 an angle of about 120 ° each. In the illustrated variant of the Fig. 1-4 there is a locking projection 13 which has an angle of approx. 135 ° to the bolt 8 and an angle of approx. 135 ° to the handle 7, since the handle 7 or the lower plate 5 also has a locking projection 14 in the area of the handle 7 has, which engages over the upper plate 4 in the closed state. The handle 7 has an angle of approximately 90 ° to the bolt 8. This locking projection 14 can be dispensed with if a second locking projection 13 is provided on the upper plate 4 in this area or, as mentioned above, at an angle of 120 ° to the bolt 8.

Da die untere Platte 5 im geschlossenen Zustand an drei Punkten, bestehend aus dem Bolzen 8, dem Verriegelungsvorsprung 13 und dem Verriegelungsvorsprung 14 (oder einem zweiten Verriegelungsvorsprung 13) an der oberen Platte 4 gehalten wird, ergibt sich ein stabiler und zuverlässiger Verschluss des Abfülldorns 1.Since the lower plate 5 in the closed state at three points, consisting of the bolt 8, the locking projection 13 and the locking projection 14 (or a second The locking projection 13) is held on the upper plate 4, resulting in a stable and reliable closure of the filling mandrel 1.

Eine weitere erfindungsgemäße Verbesserung besteht darin, zumindest einen der Griffe 6, 7 bevorzugt den Griff 6 klappbar zu befestigen. Wie dargestellt ist Griff 6 schwenkbar über einen Bolzen 15 zwischen zwei parallelen Laschen im Übergangsbereich zwischen der oberen Platte 4 und dem Hohlkörper 2 befestigt. Der Griff 6 kann dabei in der unteren Position auf der oberen Platte 4 aufliegen und gegen die Gewichtskraft oder gegen eine Federkraft, beispielsweise einer Scharnierfeder, nach oben schwenkbar sein. Der Griff 6 kann alternativ auch in der unteren Position einrasten und mit etwas Widerstand nach oben hin aus dieser Position gedrückt werden. Durch den Klappmechanismus wird verhindert, dass der Griff 6 bei zu starker Beanspruchung bricht.Another improvement according to the invention consists in attaching at least one of the handles 6, 7, preferably the handle 6, in a foldable manner. As shown, the handle 6 is pivotably attached via a bolt 15 between two parallel tabs in the transition area between the upper plate 4 and the hollow body 2. The handle 6 can rest in the lower position on the upper plate 4 and can be pivoted upwards against the force of weight or against a spring force, for example a hinge spring. Alternatively, the handle 6 can also snap into the lower position and be pressed upwards out of this position with some resistance. The folding mechanism prevents the handle 6 from breaking when it is used too heavily.

Griff 7 ist entsprechend an der unteren Platte 5 befestigt. Erfindungsgemäß jedoch sind Griff 7 und die untere Platte 5 als monolithischer Kunststoffkörper im Spritzgussverfahren gefertigt. Die obere und untere Platte 4, 5 werden bevorzugt bereits im Spritzgussverfahren mit der jeweiligen Struktur 11, 12 versehen. Weniger bevorzugt kann die Struktur 11, 12, insbesondere die Struktur 11, nachträglich angebracht werden, beispielsweise in Form von mehreren Standfüßen an die Platte 4, 5 geschraubt, genagelt, genietet oder geklebt werden. Ein Standfuß kann beispielsweise mit dem Bolzen 8 gegen die untere Platte 5 fixiert werden, oder kann Bestandteil des Kopfs des Bolzens 8 sein. Wie in den Fig. 6 und 7 veranschaulicht ist, können die Strukturen 11 und 12 in Form von drei Standfüßen zur Ausbildung eines Dreibeins angebracht oder im Spritzgussverfahren gefertigt werden, wobei die unteren Flächen der drei Standfüße die Standfläche des Abfülldorns 1 bilden. Die in den Standfüßen dargestellten Rillen können dazu verwendet werden, um mit einer Federschlauchschelle einen Stoff- oder Gewebe-Schlauch oder einen Sack anzuklemmen. Bevorzugt weist der Schlauch bzw. der Sack dazu einen Saum um seine Öffnung auf, in welchen die Federschlauchklemme oder ein ähnlicher geschlitzter Drahtring eingenäht ist. Besonders bevorzugt kann so ein kurzer Stoffschlauchabschnitt schnell befestigt werden, an welchen ein Füllrohr anschließt, wodurch das Füllrohr vorteilhaft unabhängig vom Abfülldorn 1 aufgrund des flexiblen Stoffabschnitts geschwenkt werden kann. Die Standfüße können auch Gewinde aufweisen, an welchen ein Aufsatz oder ein Füllstutzen angeschraubt werden kann.Handle 7 is correspondingly attached to the lower plate 5. According to the invention, however, the handle 7 and the lower plate 5 are manufactured as a monolithic plastic body in an injection molding process. The upper and lower plates 4, 5 are preferably provided with the respective structure 11, 12 in the injection molding process. Less preferably, the structure 11, 12, in particular the structure 11, can be attached subsequently, for example screwed, nailed, riveted or glued to the plate 4, 5 in the form of several feet. A stand can be fixed against the lower plate 5 with the bolt 8, for example, or it can be part of the head of the bolt 8. As in the Figures 6 and 7 As is illustrated, the structures 11 and 12 can be attached in the form of three feet to form a tripod or manufactured using the injection molding process, the lower surfaces of the three feet forming the footprint of the filling mandrel 1. The grooves shown in the feet can be used to clamp a fabric hose or a sack with a spring hose clamp. For this purpose, the hose or the sack preferably has a hem around its opening into which the spring hose clamp or a similar slotted wire ring is sewn. Particularly preferably, a short fabric hose section can be quickly attached to which a filling tube is connected, whereby the filling tube can advantageously be pivoted independently of the filling mandrel 1 due to the flexible fabric section. The feet can also have threads to which an attachment or a filler neck can be screwed.

Die beanspruchten erfindungsgemäßen technischen Merkmale der beschriebenen Ausführungsvarianten können im Rahmen des fachmännischen Handelns beliebig kombiniert werden. Der beanspruchte Schutzumfang richtet sich ausschließlich nach der im unabhängigen Anspruch definierten Merkmalskombination.The claimed technical features according to the invention of the embodiment variants described can be combined as desired within the scope of professional action. The claimed scope of protection is based exclusively on the combination of features defined in the independent claim.

Die Fig. 8 bis 11 zeigen alle denselben besonders bevorzugten erfindungsgemäßen Abfülldorn 1. Der Abfülldorn 1 weist einen Hohlkörper 2 auf, welcher bevorzugt einen zylindrischen Mantel aufweist. Am oberen Ende des Hohlkörpers 2 verlaufen mehrere Streben 3 zu einer Spitze zusammen. Am unteren Ende geht der Hohlkörper 2 in die obere Platte 4 über, welche außen an den Zylinder anschließt und die innere Öffnung des Hohlkörpers 2 bevorzugt zur Gänze offen lässt. Der Hohlkörper 2, die obere Platte 4 und die die Spitze bildenden Streben 3 werden bevorzugt als monolithischer Kunststoffkörper im Spritzgussverfahren gefertigt.The Figs. 8-11 all show the same particularly preferred filling mandrel 1 according to the invention. The filling mandrel 1 has a hollow body 2, which preferably has a cylindrical jacket. At the upper end of the hollow body 2, several struts 3 run to a point together. At the lower end, the hollow body 2 merges into the upper plate 4, which connects to the outside of the cylinder and preferably leaves the inner opening of the hollow body 2 completely open. The hollow body 2, the upper plate 4 and the struts 3 forming the tip are preferably manufactured as a monolithic plastic body in an injection molding process.

Um die untere Öffnung des Hohlkörpers 2 bzw. der oberen Platte 4 verschließbar zu machen, ist eine schwenkbare untere Platte 5 vorgesehen. Die obere Platte 4 ist mit einem Griff 6 versehen und die untere Platte 5 ist mit einem Griff 7 versehen, welche im geschlossenen Zustand des Verschlusses bevorzugt diametral gegenüber liegen. Die obere Platte 4 und die untere Platte 5 weisen je eine Bohrung auf, durch welche der Bolzen 8 verläuft, wobei der Bolzen 8 in zumindest einer dieser Bohrungen schwenkbar gehalten ist. Die untere Platte 5 kann um die Achse des Bolzens 8 geschwenkt werden, um die Öffnung des Hohlkörpers 2 nach unten hin frei zu geben, wie in Fig. 10 zu erkennen ist.In order to make the lower opening of the hollow body 2 or the upper plate 4 closable, a pivotable lower plate 5 is provided. The upper plate 4 is provided with a handle 6 and the lower plate 5 is provided with a handle 7, which in the closed state of the closure are preferably diametrically opposite. The upper plate 4 and the lower plate 5 each have a bore through which the bolt 8 runs, the bolt 8 being held pivotably in at least one of these bores. The lower plate 5 can be pivoted about the axis of the bolt 8 in order to free the opening of the hollow body 2 downwards, as in FIG Fig. 10 can be seen.

Die wesentliche erfindungsgemäße Verbesserung betrifft den Verschluss bzw. die Bodenfläche des Abfülldorns 1. Erfindungsgemäß ist vorgesehen, die untere Platte 5 mit einer Struktur 12 zu versehen, welche zumindest einen Teil der Standfläche des Abfülldorns 1 bildet. Der Kopf des Bolzens 8 ragt maximal bis zur Standfläche vor und ist bevorzugt in einer Aussparung der Struktur 12 aufgenommen. Wie insbesondere in Fig. 10 gut zu erkennen ist, ist es ausreichend die Struktur 12 als Stege am Rand der unteren Platte 5 auszuführen. Alternativ kann bei der unteren Platte 5 nahezu die gesamte Fläche mit der Struktur 12 versehen werden, mit Ausnahme der Aussparung für den Kopf des Bolzens 8. Eine besonders gute Standfestigkeit ergibt sich, wenn die durch die Struktur 12 gebildete Standfläche einen annähernd quadratischen Umfang aufweist. Wie in Fig. 10 veranschaulicht ist, kann die Struktur 11 am Griff 6 der oberen Platte 4 vorliegen, sodass der Griff 6 der oberen Platte 4 einen Teil der Standfläche bildet, wobei dieser bei starker Hebelwirkung (beispielsweise wenn der Schüttgutbehälter schräg abgesetzt wird oder beim Absetzen schwingt) über das Scharniergelenk nach oben wegklappt, bevor er bricht. Wäre der Griff 6 monolithisch mit dem Hohlkörper 2 verbunden, so müsste beim Abbrechen des Griffs 6 zudem nachteilig der gesamte Spritzgussteil ersetzt werden. In einer Ausführungsvariante kann die Struktur 11 am Griff 6 im geschlossenem Zustand die untere Platte 5 überragen, wobei in diesem Fall die untere Platte 5 im Bereich der diese überlappenden Struktur 11 des Griffs 6 keine Struktur 12 aufweist oder eine Fase 16 oder Abrundung aufweisen kann, wodurch die Struktur 11 am Griff 6 einen Verriegelungsvorsprung 13 für die untere Platte 5 bildet. Die Struktur 11 bzw. der Verriegelungsvorsprung 13 des Griffs 6 ist dabei bevorzugt so ausgeführt, dass das Aufwärtsklappen des Griffes 6 nicht behindert wird, beispielsweise kann die Struktur 11 dazu an ihrer dem Boden zugewandten Kante eine Rundung aufweisen.The main improvement according to the invention relates to the closure or the bottom surface of the filling mandrel 1. According to the invention, the lower plate 5 is provided with a structure 12 which forms at least part of the standing surface of the filling mandrel 1. The head of the bolt 8 protrudes at most up to the standing surface and is preferably received in a recess in the structure 12. As in particular in Fig. 10 As can be clearly seen, it is sufficient to design the structure 12 as webs on the edge of the lower plate 5. Alternatively, almost the entire surface of the lower plate 5 can be provided with the structure 12, with the exception of the recess for the head of the bolt 8. Particularly good stability results when the standing surface formed by the structure 12 has an approximately square circumference. As in Fig. 10 is illustrated, the structure 11 can be on the handle 6 of the upper plate 4, so that the handle 6 of the upper plate 4 forms part of the standing surface, with this when there is a strong leverage (for example when the bulk goods container is set down at an angle or swings when set down) over the The hinge joint folds up before it breaks. If the handle 6 were monolithically connected to the hollow body 2, then if the handle 6 were broken off, the entire injection-molded part would also have to be disadvantageously replaced. In one embodiment, the structure 11 on the handle 6 can project beyond the lower plate 5 in the closed state, in which case the lower plate 5 does not have a structure 12 in the area of the overlapping structure 11 of the handle 6 or can have a bevel 16 or rounding, whereby the structure 11 on the handle 6 forms a locking projection 13 for the lower plate 5. The structure 11 or the locking projection 13 of the handle 6 is preferably designed in such a way that the upward folding of the handle 6 is not hindered, for example the structure 11 can have a rounding on its edge facing the floor.

Wie in den Fig. 8 bis 11 zu erkennen ist, ist der Verriegelungsvorsprung 14 bevorzugt zweigeteilt ausgeführt, wobei die beiden Teile des Verriegelungsvorsprungs 14 seitlich vom Griff 7 abragen und die obere Platte 4 beabstandet zueinander jeweils seitlich vom Griff 7 übergreifen. Bevorzugt weist die untere Platte 5 im Bereich der beiden Teile des Verriegelungsvorsprungs 14 jeweils eine korrespondierende Aussparung auf, sodass das Schließen des Abfülldorns 1 leicht und zuverlässig funktioniert. Bevorzugt weist die obere Platte 4 einen annähernd rechteckigen bzw. bevorzugt quadratischen Umfang auf, wobei die untere Platte 5 im geschlossenen Zustand zumindest die Öffnung der oberen Platte 4 und die Eckbereiche des zumindest annähernd quadratischen Umfangs abdeckt und zumindest in diesen Eckbereichen mit einer Struktur 12 versehen ist, welche die Standfläche bzw. vier Standbeine des Abfülldorns 1 bildet. Durch die Ausgestaltung der Standfläche als Vieleck, insbesondere als Drei- oder Viereck, ergibt sich eine wesentliche Verbesserung gegenüber runden, bzw. kreisförmigen Standflächen. Als annähernd quadratischer Umfang ist insbesondere auch der dargestellte Umfang mit abgerundeten Ecken zu verstehen, bei welchem die Seitenkanten des Quadrats zudem nach außen gewölbt sind. Allgemeiner ausgedrückt hat die Standfläche des Abfülldorns 1, bzw. die Form der Struktur 12 eine andere als kreisförmige Form.As in the Figs. 8-11 As can be seen, the locking projection 14 is preferably designed in two parts, the two parts of the locking projection 14 protruding laterally from the handle 7 and the upper plate 4 spaced apart from one another laterally overlapping the handle 7. The lower plate 5 preferably has one each in the area of the two parts of the locking projection 14 Corresponding recess so that the closing of the filling mandrel 1 works easily and reliably. The upper plate 4 preferably has an approximately rectangular or preferably square circumference, the lower plate 5 in the closed state at least covering the opening of the upper plate 4 and the corner areas of the at least approximately square circumference and being provided with a structure 12 at least in these corner areas is, which forms the base or four legs of the filling mandrel 1. The design of the standing area as a polygon, in particular as a triangle or square, results in a significant improvement over round or circular standing areas. An approximately square circumference is to be understood in particular as the illustrated circumference with rounded corners, in which the side edges of the square are also curved outward. In more general terms, the standing surface of the filling mandrel 1 or the shape of the structure 12 has a shape other than circular.

Durch die um den Umfang verlaufende Struktur 12 wird die Steifigkeit bzw. der Biegewiderstand der unteren Platte 5 erhöht, sodass ein Durchbiegen der unteren Platte 5 verhindert wird.The structure 12 running around the circumference increases the rigidity or the bending resistance of the lower plate 5, so that bending of the lower plate 5 is prevented.

In den Fig. 12 und 13 ist eine weitere Ausführungsvariante einer erfindungsgemäßen Abfüllvorrichtung gezeigt, bei welcher am Hohlkörper 2 keine Streben 3, keine Widerhaken 9 und keine Öffnungen 10 vorhanden sind. Der Hohlkörper 2 weist einen Vorsprung 17 auf, welcher um den Umfang des Hohlkörpers 2 verläuft, also durch eine sprunghafte Vergrößerung des Außenumfangs des Hohlkörpers 2 gebildet ist. Der Vorsprung 17 befindet sich bevorzugt unmittelbar am oberen Ende des Hohlkörpers 2. Die anderen vorhandenen Teile der Vorrichtung, nämlich die obere Platte 4, untere Platte 5, der bevorzugt klappbarer Griff 6, der Griff 7, der Bolzen 8 und die Struktur 12 können wie dargestellt ident zu der vorherigen Ausführungsvariante ausgeführt sein. Die erfindungsgemäße Ausführungsvariante der Fig. 12 bis 13 wird anders als der Abfülldorn 1 nicht durch die Hülle eines Schüttgutbehälters gestochen, sondern in der verschließbaren Öffnung eines flexiblen Mehrweg-Schüttgutbehälters 18 platziert.In the Figures 12 and 13 Another embodiment of a filling device according to the invention is shown in which no struts 3, no barbs 9 and no openings 10 are present on the hollow body 2. The hollow body 2 has a projection 17 which runs around the circumference of the hollow body 2, that is to say is formed by a sudden increase in the outer circumference of the hollow body 2. The projection 17 is preferably located directly at the upper end of the hollow body 2. The other existing parts of the device, namely the upper plate 4, lower plate 5, the preferably foldable handle 6, the handle 7, the bolt 8 and the structure 12 can as shown to be identical to the previous variant. The inventive variant of the Figs. 12 to 13 Unlike the filling mandrel 1, it is not pierced through the shell of a bulk goods container, but is placed in the closable opening of a flexible reusable bulk goods container 18.

Das Anschließen eines Mehrweg-Schüttgutbehälters 18 an die erfindungsgemäße Abfüllvorrichtung ist in Fig. 14 veranschaulicht. Der Mehrweg-Schüttgutbehälter 18 weist an seinem unteren Ende ein offenes Ende auf, welches üblicherweise mit einem geringeren Querschnitt vorliegt als der darüber liegende Bereich des Mehrweg-Schüttgutbehälters 18. Wie mit gestrichten Linien dargestellt, ist das offene Ende verschlossen, beispielsweise abgebunden mit einem Band 19.The connection of a reusable bulk goods container 18 to the filling device according to the invention is shown in FIG Fig. 14 illustrated. The reusable bulk material container 18 has an open end at its lower end, which is usually present with a smaller cross section than the area of the reusable bulk material container 18 located above it. As shown with dashed lines, the open end is closed, for example tied with a tape 19th

Um den Mehrweg-Schüttgutbehälters 18 zu entleeren, wird das Band 19 geöffnet und das Schüttgut entweicht durch das offene Ende.In order to empty the reusable bulk material container 18, the belt 19 is opened and the bulk material escapes through the open end.

Die erfindungsgemäße Abfüllvorrichtung kann verwendet werden, um den Inhalt des Mehrweg-Schüttgutbehälters 18 dosiert zu entleeren. Dazu wird beim noch geschlossenen Mehrweg-Schüttgutbehälter 18 der Hohlkörper 2 unterhalb des Bandes 19 in das offene Ende eingeführt, wonach dieses außen am Hohlkörper 2 fixiert wird, bevorzugt mit einer Rohrschelle bzw. einem Spannring 20, welcher in Fig. 14 gepunktet dargestellt ist. Der Spannring 20 kann vorteilhaft über einen Hebel 21 geschlossen bzw. geöffnet werden, um das Anbringen und Lösen werkzeuglos zu ermöglichen.The filling device according to the invention can be used to empty the contents of the reusable bulk goods container 18 in a metered manner. For this purpose, when the returnable bulk goods container 18 is still closed, the hollow body 2 is inserted below the belt 19 into the open end, after which it is fixed on the outside of the hollow body 2, preferably with a pipe clamp or a Clamping ring 20, which in Fig. 14 is shown dotted. The clamping ring 20 can advantageously be closed or opened via a lever 21 in order to enable attachment and detachment without tools.

Ist der Spannring 20 geschlossen, fixiert dieser das Gewebe des offenen Endes des Mehrweg-Schüttgutbehälters 18 von außen gegen den Hohlkörper 2, wobei der Vorsprung 17 verhindert, dass der Spannring 20 vom Hohlkörper 2 rutschen kann. In diesem Zustand kann das Band 19 gelöst werden, sodass das Schüttgut des geöffneten Mehrweg-Schüttgutbehälters 18 (gepunktet dargestellt) durch den Hohlkörper 2 bis zur unteren Platte 5 gelangt und an dieser anliegt. Durch Schwenken der unteren Platte 5 um den Bolzen 8, kann die erfindungsgemäße Abfüllvorrichtung geöffnet und Material aus dem Mehrweg-Schüttgutbehälter 18 dosiert entnommen werden. Vorteilhaft gegenüber bekannten transportablen, manuellen Dosiervorrichtungen zur Entnahme von Material aus einem Mehrweg-Schüttgutbehälter 18 ist, dass die erfindungsgemäße Abfüllvorrichtung eine verbesserte Standfestigkeit und bevorzugt zumindest einen klappbaren Griff 6 aufweist, sodass ein voller oder teilentleerter Mehrweg-Schüttgutbehälter 18 mitsamt der erfindungsgemäßen Abfüllvorrichtung am Boden abgestellt werden kann, ohne eine Beschädigung der Abfüllvorrichtung zu riskieren. Insbesondere für landwirtschaftliche Betriebe ist dies besonders vorteilhaft, da die Mehrweg-Schüttgutbehälter 18, beispielsweise Bigbags, meist mit einem Stapler oder Frontlader angehoben werden, wobei nach Abstellen des Bigbags mitsamt der erfindungsgemäßen Abfüllvorrichtung, der Stapler oder Frontlader sofort für andere Aufgaben zur Verfügung steht. Ein aufwendiges Entfernen der Dosiervorrichtungen vom vollen oder teilentleerten Bigbag kann also unterbleiben.If the clamping ring 20 is closed, it fixes the tissue of the open end of the reusable bulk goods container 18 from the outside against the hollow body 2, the projection 17 preventing the clamping ring 20 from slipping off the hollow body 2. In this state, the belt 19 can be loosened so that the bulk material of the opened reusable bulk material container 18 (shown in dotted lines) passes through the hollow body 2 to the lower plate 5 and rests against it. By pivoting the lower plate 5 around the bolt 8, the filling device according to the invention can be opened and material can be removed from the reusable bulk goods container 18 in a metered manner. The advantage over known transportable, manual dosing devices for removing material from a reusable bulk goods container 18 is that the filling device according to the invention has improved stability and preferably at least one foldable handle 6, so that a full or partially emptied reusable bulk material container 18 together with the filling device according to the invention is on the floor can be turned off without risking damage to the filling device. This is particularly advantageous for agricultural businesses, since the reusable bulk material containers 18, for example big bags, are usually lifted with a forklift or front loader, with the forklift or front loader being immediately available for other tasks after the big bag and the filling device according to the invention have been placed. A laborious removal of the dosing devices from the full or partially emptied big bag can therefore be omitted.
