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 Doms bekannt, welche Abfüllvorrichtungen 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 A flexible bulk container is a large sack made of fabric or plastic fabric, which is known under the name Bigbag. In order to quickly empty the big bag completely, it is usually lifted and the bottom surface cut open with a knife. In order to be able to meter the emptying, filling devices in the form of a dome are known, which filling devices are inserted with their tips first into the plastic fabric from below so that they penetrate into the bulk material. The bulk material can be removed from the flexible through openings in the filling device

Die FR2895728A3 zeigt eine Abfüllvorrichtung in Form eines Abfülldoms für Bigbags. Der Abfülldom hat einen zylindrischen Hohlkörper, an dessen oberen Ende mehrere Streben zu einer Spitze The FR2895728A3 shows a filling device in the form of a filling dome for big bags. The filling dome has a cylindrical hollow body, at the upper end of which several struts form a tip
zusammenlaufen. Beabstandet zu den Streben weist der Abfülldom 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 aneinanderhegenden Platten gebildet ist, wobei die obere Platte fest mit dem zylindrischen converge. At a distance from the struts, the filling dome 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 adjoining plates, the upper plate being fixed to the cylindrical one
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 Abfülldom wird mit der Spitze in den Bigbag eingestochen, bis die Widerhaken in den Bigbag eindringen. Dann wird der Abfülldom 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. Hollow body is connected and has a central opening and the lower plate is designed over the entire surface and is pivotally attached to the upper plate with a threaded bolt. The filling dome is inserted into the big bag with the tip until the barbs enter the big bag. Then the filling dome is pulled back a little so that the barbs rest against the inside of the fabric of the big bag. Bulk material can now enter the cylindrical hollow body between the struts and through the openings above the barbs. By swiveling the lower plate around the threaded bolt, the closure is opened and the bulk material goes down through the cylindrical hollow body. Both plates are equipped with handles so that the swivel movement can be carried out by hand.
Die EP 2937291 Al zeigt eine Erweiterung der Vorrichtung der FR 2895728 A3 um einen Füllstutzen, welcher bei Bedarf bei bereits eingestochenem Abfülldom von unten an die obere Platte geschraubt werden kann. Ansonsten sind die Vorrichtungen ident, wobei weder der Abfülldom noch der Füllstutzen eine zufriedenstellende Standfläche aufweisen. EP 2937291 A1 shows an extension of the device of FR 2895728 A3 by a filler neck, which can be screwed onto the upper plate from below if the filling dome is already inserted. The devices are otherwise identical, with neither the filling dome nor the filling nozzle having a satisfactory footprint.
Die WO 2018009952 Al zeigt einen Abfülldom mit einer verbesserten Standfläche, um Beschädigungen im Bereich der Platten oder der Griffe des Verschlusses zu vermeiden. Während die Vorrichtung der EP 2937291 Al und der FR 2895728 A3 geschweißte Vorrichtungen aus Blech zu sein scheinen, handelt es sich bei den Teilen der Vorrichtung der WO 2018009952 Al um Kunststoffteile. Aufgabe der gegenständlichen Erfindung ist es, einen verbesserten Abfülldom bereit zu stellen. WO 2018009952 A1 shows a filling dome with an improved standing area in order to avoid damage in the area of the plates or the handles of the closure. While the device of EP 2937291 Al and FR 2895728 A3 seem to be welded devices made of sheet metal, the parts of the device of WO 2018009952 Al are plastic parts. The object of the present invention is to provide an improved filling dome.

Fig. 3 zeigt einen erfmdungsgemäßen Abfülldom. Die folgenden Absätze beschreiben anhand der Fig. 1- 2 die bereits bekannten Merkmale des Abfülldoms 1. 3 shows a filling dome according to the invention. The following paragraphs describe the already known features of the filling dome 1 with reference to FIGS. 1-2.
Der Abfülldom 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 Stabibtätsgründen und aufgrund der bevorzugten 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 offenlässt. Der Hohlkörper 2, die obere Platte 4 und die die Spitze bildenden Streben 3 werden bevorzugt als monolithischer Kunststoffkörper im Spritzgussverfahren gefertigt. Die geringen Rundungen, welche am oberen Rand des Hohlkörpers 2 an den Streben 3 vorliegen, sind dem Spritzgussverfahren geschuldet. The filling dome 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 together to form a tip. For reasons of stability and because of the preferred production in the plastic injection molding process, four struts 3, which are evenly distributed over the circumference of the cylinder, have proven to be the most technically advantageous 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 preferred as monolithic Plastic body made by injection molding. The slight curves that are present on the struts 3 at the upper edge of the hollow body 2 are due to the 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. 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 are preferably diametrically opposite in the closed state of the closure. The upper plate 4 and the lower plate 5 each have a bore through which the bolt 8 runs, the bolt 8 being pivotally held in at least one of these bores. The lower plate 5 can be pivoted about the axis of the bolt 8 in order to expose the opening of the hollow body 2 downwards.
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. Die 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 they are pressed downwards against the hollow body 2 by the tissue of the big bag so as not to close the opening in the tissue enlarge. If the barbs 9 are moved completely through the tissue, they go back to their starting position and spread back against the inside of the tissue. A little above the barb 9 there are openings 10 in the lateral surface of the hollow body 2 in order to enable an almost complete emptying of the big bag. 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. The
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. Die Widerhaken 9 können aber auch mittels Schraube und Mutter fixiert werden. Als Material eignet sich relativ fester Gummi. Barbs 9 are known from the prior art as strips of resilient elastic material and are guided inwards by slots in the hollow body 2 and fastened above the slots on the inside of the hollow body 2 by rivets. The barbs 9 can also be fixed by means of a screw and nut. Relatively solid rubber is suitable as the material.
Es kann vorgesehen sein, die obere Platte 4 mit einer Struktur zu versehen, welche einen Teil der Standfläche des Abfülldoms 1 bildet. Alternativ oder zusätzlich kann vorgesehen sein, die untere Platte 5 mit einer Struktur zu versehen, welche einen Teil der Standfläche des Abfülldoms 1 bildet. Der Kopf des Bolzens 8 ragt maximal bis zur Standfläche vor und ist bevorzugt in einer Aussparung der Struktur der unteren Platte 5 aufgenommen. Es ist ausreichend die Strukturen als Stege am Rand der jeweiligen Platte 4, 5 auszuführen. Alternativ kann bei der unteren Platte 5 nahezu die gesamte Fläche mit einer Struktur versehen werden, mit Ausnahme der Aussparung für den Kopf des Bolzens 8. Eine besonders gute Standfestigkeit ergibt sich, wenn die durch die Struktur gebildete Standfläche einen annähernd quadratischen Umfang aufweist. Die Unterseiten der Griffe 6, 7 können mit der Standfläche eine ebene Fläche bilden, also mit der Struktur koplanar abschließen. It can be provided that the upper plate 4 is provided with a structure which forms part of the standing area of the filling dome 1. Alternatively or additionally, provision can be made for the lower plate 5 to be provided with a structure which forms part of the standing surface of the filling dome 1. The head of the bolt 8 projects at most up to the standing surface and is preferably received in a recess in the structure of the lower plate 5. It is sufficient to design the structures as webs on the edge of the respective plate 4, 5. Alternatively, in the case of the lower plate 5, almost the entire surface can be provided with a structure, with the exception of the recess for the head of the bolt 8. A particularly good stability is obtained if the base surface formed by the structure 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 they can be coplanar with the structure.
Zumindest einer der Griffe 6, 7 bevorzugt der Griff 6 kann klappbar befestigt sein. Wie dargestellt ist Griff 6 schwenkbar über einen Bolzen zwischen zwei parallelen Laschen 11 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 Schamierfeder, 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. Eine besonders gute Standfestigkeit ergibt sich, wenn die durch die Struktur gebildete Standfläche der unteren Platte 5 einen annähernd quadratischen Umfang aufweist. 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 versehen ist, welche die Standfläche bzw. vier Standbeine des Abfülldoms 1 bildet. Durch die At least one of the handles 6, 7, preferably the handle 6, can be fastened in a foldable manner. As shown, handle 6 is pivotally attached via a bolt between two parallel tabs 11 in the transition region 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 upward against the weight or against a spring force, for example a hinge spring. Alternatively, the handle 6 can also snap into the lower position and be pushed upwards out of this position with some resistance. The folding mechanism prevents the handle 6 from breaking when the load is too high. A particularly good stability results if the base surface of the lower plate 5 formed by the structure has an approximately square circumference. The upper plate 4 preferably has an approximately rectangular or preferably square circumference, the lower plate 5 in the closed state covering at least the opening of the upper plate 4 and the corner regions of the at least approximately square circumference and being provided with a structure at least in these corner regions , which forms the base or four pillars of the filling dome 1. Through the
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 Abfülldoms 1, bzw. die Form der Struktur eine andere als kreisförmige Form. Designing the stand area as a polygon, in particular as a triangle or quadrangle, results in a significant improvement over round or circular stand areas. An approximately square circumference is also to be understood in particular as the circumference shown with rounded corners, in which the side edges of the square are also curved outwards. Expressed more generally, the footprint of the filling dome 1 or the shape of the structure has a shape other than circular.
Durch die um den Umfang verlaufende Struktur wird die Steifigkeit bzw. der Biegewiderstand der unteren Platte 5 erhöht, sodass ein Durchbiegen der unteren Platte 5 verhindert wird. The structure 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.
Wie aus den Fig. 3 bis 6 ersichtlich ist, besteht die erfindungsgemäße Verbesserung darin, an den Streben 3, welche die Spitze des Abfülldoms 1 ausbilden, zusätzliche Querstreben 12 vorzusehen. Von jeder Strebe 3 ragt zumindest eine Querstrebe 12 ab, welche mit ihrer unteren Kante 13 am Hohlkörper 2 anliegt, bevorzugt in diesen übergeht. Jede Querstrebe 12 liegt mit einer nach oben innen geneigt verlaufenden Kante 14 an der jeweiligen Strebe 3 an. Die Streben 3 sind jeweils flächige bzw. As can be seen from FIGS. 3 to 6, the improvement according to the invention consists in providing additional cross struts 12 on the struts 3 which form the tip of the filling dome 1. At least one cross strut 12 protrudes from each strut 3, which abuts the hollow body 2 with its lower edge 13, preferably merging into the latter. Each cross strut 12 bears against the respective strut 3 with an edge 14 which slopes upwards inwards. The struts 3 are flat or
plattenförmige Elemente, deren Fläche radial ausgerichtet sind. Jede Strebe 3 ist über eine senkrechte Außenkante 15 mit der Innenfläche 16 des Hohlkörpers 2 verbunden. Jede Strebe 3 verläuft ausgehend vom Hohlkörper 2 nach oben und nach innen geneigt, sodass sich die Streben 3 am oberen Ende des Abfülldoms 1 unter Ausbildung einer Spitze treffen.
