Abstract
Description
Einrichtung zum Füllen eines Behältnisses mit einem körnigen Stoff Device for filling a container with a granular substance
Die Erfindung betrifft, eine Einrichtung zum Füllen eines einseitig offenen Behältnisses mit einem körnigen Stoff, insbesondere eines Formkastens einer Formkombination mit Giesserei formstoff, mit einem Füllbehälter mit Bodenverschluss.The invention relates to a device for filling a container open on one side with a granular substance, in particular a molding box of a mold combination with foundry molding material, with a filling container with a bottom closure.
Zum Füllen eines Behältnisses mit einem körnigen Stoff, insbesondere eines Formkastens mit Giessereiformstoff bei der Herstellung von Giessereiformen, wird vorzugsweise ein Füllbehälter verwendet der mit einem Bodenverschluss ausgerüstet ist, der eine Vielzahl von gleichzeitig betätigbaren Klappen aufweist.For filling a container with a granular substance, in particular a molding box with foundry molding material in the production of foundry molds, a filling container is preferably used which is equipped with a bottom closure which has a plurality of flaps which can be actuated at the same time.
Solche Füllbehälter werden entsprechend dem Füllvolumen der Formkasten mit einer dosierten Menge Formstoff beschickt.Such filling containers are charged with a metered amount of molding material according to the filling volume of the molding box.
Werden nun beim Füllen die Klappen geöffnet, fällt die gesamte Formstoffmasse gleichzeitig in den darunter aufgestellten Formkasten, wobei die fallende Formstoffmasse die Wirkung eines kolbenartigen Verdrängers ausübt. Dadurch wird die im Formkasten eingeschlossene Luft nach den Seiten hin verdrängt und reisst beim Entweichen in die Umgebung, Teile der Formstoffmasse mit. Luft, die dabei nicht entweichen kann, wird von der Sandmasse umschlossen und verhindert damit eine homogene Formstoffüllung des Formkastens, da dabei die einzelnen Formstoffpartikel im Volumen ungleich verteilt sind.If the flaps are now opened during filling, the entire molding material mass simultaneously falls into the molding box below, the falling molding material mass acting as a piston-like displacer. This traps the air trapped in the molding box to the sides displaces and tears away parts of the molding material when it escapes into the environment. Air that cannot escape is enclosed by the sand mass and thus prevents a homogeneous molding material filling of the molding box, since the individual molding material particles are unevenly distributed in volume.
Aus der DE-PS 1 758 414 (Bührer) ist in diesem Zusammenhang eine Einrichtung ersichtlich (Fig. 4) bei welcher über eine Kombination von Füllrahmen und Formkasten ein Füllbehälter gefahren ist. Zur Erweiterung der Füllrahmenöffnung zwecks besserer Füllung, ist hier ein trichterförmiger Rahmen aufgesetzt,der die fallende Formstoffmasse zum Füllrahmen hin leiten soll. Durch die Erveiterung wird wohl die Formstoffmasse praktisch verlustfrei in den Formkasten geleitet, jedoch auch eine grössere Fläche als die des Formkastens abgedeckt. Dadurch kann die im Formkasten befindliche Luft nur schwer entweichen und verhindert damit eine homogene Füllung und stösst beim Entweichen eine beträchtliche Menge Formstoff in die Umgebung. Neben der Belastung der Umgebungsluft durch schwebende Formstoffpartikel ist auch der ausgetragene Formstoff, ein nicht unwesentlicher Verlustfaktor.In this connection, a device can be seen from DE-PS 1 758 414 (Bührer) (FIG. 4) in which a filling container has been moved via a combination of filling frame and molding box. To expand the filling frame opening for better filling, a funnel-shaped frame is placed here, which should guide the falling molding material to the filling frame. As a result of the expansion, the molding material mass is fed into the molding box practically without loss, but also covers a larger area than that of the molding box. As a result, the air in the molding box can escape only with difficulty and thus prevents a homogeneous filling and pushes a considerable amount of molding material into the environment during the escape. In addition to the pollution of the ambient air by floating molding material particles, the discharged molding material is also a not insignificant loss factor.
Die Aufgabe der Erfindung besteht darin, eine Einrichtung zu schaffen, mittels welcher ohne Belastung der Umwelt und auf einfache Weise eine dosierte Menge eines körnigen Stoffes verlustfrei in einen Behälter gebracht werden kann, wobei die durch die fallende Masse verdrängte Luft störungsfrei abgeführt wird.The object of the invention is to provide a device by means of which a metered amount of a granular substance can be easily and without loss into a container without polluting the environment, the air displaced by the falling mass being discharged without interference.

Fig. 1 zeigt in vereinfachter Darstellung eine erfindungs gemässe Einrichtung mit möglicher Verwendung in einer Formanlage.Fig. 1 shows a simplified representation of an inventive device with possible use in a molding system.
Die Einrichtung besteht im wesentlichen aus einem Füllbehälter 1 mit einer oberen Oeffnung 2 und einer unteren Oeffnung 3. An der oberen Oeffnung 2 ist der Füllbehälter 1 mit einem trichterförmigen Kragen 4 versehen, während die untere Oeffnung 3 mit einem Bodenverschluss 5 ausgerüstet ist, der aus einer Mehrzahl von betätigbaren Klappen 6 besteht. Die Seitenwände 7 des Füllbehälters 1 erweitern sich vom Uebergang zum Kragen 4 der oberen Oeffnung 2 konisch zur unteren Oeffnung 3 hin, wodurch ein verbessertes AusfHessen einer Formstoffmasse 8 erzielt wird.The device essentially consists of a filling container 1 with an upper opening 2 and a lower opening 3. At the upper opening 2, the filling container 1 is provided with a funnel-shaped collar 4, while the lower opening 3 is equipped with a bottom closure 5, which consists of a plurality of actuatable flaps 6. The side walls 7 of the filling container 1 widen conically from the transition to the collar 4 of the upper opening 2 towards the lower opening 3, whereby an improved measurement of a molding material mass 8 is achieved.
Den Füllbehälter 1 umschliesst in einem Abstand 10 ein mit dem Füllbehälter 1 verbundener Sehälterrahiπen 9 dessen innere Querschnittsfläche an die Querschnittsfläche eines Füllrahmens 11 angeglichen ist. Der Füllrahiaen 11 ist hierbei mit einem guerschnittsgleichen Formkasten 12 verbunden, der auf einer Modellplatte 13 mit Modell 14 aufliegt. Füllrahmen 11, Formkasten 12 und Modellplatte 13 bilden zusammen eine Form kombination in welche zur Formherstellung eine dosierte Menge der Formstoffmasse 8 eingefüllt wird.The filling container 1 encloses at a distance 10 a Sehalterrahiπen 9 connected to the filling container 1 whose inner cross-sectional area is matched to the cross-sectional area of a filling frame 11. The Füllrahiaen 11 is connected to a cross-section molded box 12 which rests on a model plate 13 with model 14. Filling frame 11, molding box 12 and model plate 13 together form a shape Combination in which a metered amount of the molding material mass 8 is filled for the production of the mold.
Der Abstand 10 zwischen dem Füllbehälter 1 und dem Behälterrahmen 9 ist entsprechend dem verdrängbaren Luftvolumen des Formkastens 12 gewählt. Durch die Anordnung des Abstandes 10 wird die innere horizontale Querschnittsfläche des Füllbehälters 1 geringer als die innere horizontale Querschnittsfläche des Formkastens 12 wodurch die beim Füllen des Formkastens 12 verdrängte Luft über die Querschnittsfläche des Abstandes 10 störungsfrei abfHessen kann.The distance 10 between the filling container 1 and the container frame 9 is selected in accordance with the displaceable air volume of the molding box 12. The arrangement of the distance 10 means that the inner horizontal cross-sectional area of the filling container 1 is smaller than the inner horizontal cross-sectional area of the molding box 12, which means that the air displaced when the molding box 12 is filled can be measured without interference over the cross-sectional area of the distance 10.
Fig. 2 zeigt eine Variante mit einem Füllbehälter 20 dessen obere Oeffnung 21 ebenfalls einen trichterförmigen Kragen 22 aufweist. Die untere Oeffnung 23 ist wiederum mit einem aus betätigbaren Klappen 24 gebildeten 3odenverschluss 25 versehen. Anstelle der Klappen 24 kann auch ein Bodenverschluss verwendet werden der z.B. mit einem Schieber oder dergleichen ausgerüstet ist . Im Füllbehälter 20 ist mindestens ein rohrförmiger Hohlkörper 26 eingesetzt dessen oberes Ende mit einer querschnittsüberdeckenden Abschirmung 27 versehen ist. Der rohrförmige Hohlkörper 26 ist vorteilhaft zum Bodenverschluss hin konisch verengend ausgeführt um der fallenden Formstoffmasse 8 geringstmöglichen Widerstand entgegen zu setzen. Mit gleicher Funktion sind auch die Seitenwändε 28 des Füllbehälters 20 zum Bodenverschluss 25 hin, den horizontalen Raumquerschnitt des Füllbehälters 20 konisch erweiternd, angeordnet. Der rohrförmige Hohlkörper 26 ist annähernd auf den Klappen 24 des Bodenverschlusses 25 aufliegend eingesetzt womit ein möglichst günstiges Abströmen der beim Einfüllen der Formstoffmasse in den Formkasten 12 verdrängten Luft erreichbar ist.Fig. 2 shows a variant with a filling container 20, the upper opening 21 also has a funnel-shaped collar 22. The lower opening 23 is in turn provided with a 3ode closure 25 formed from actuatable flaps 24. Instead of the flaps 24, a bottom lock can also be used, e.g. is equipped with a slide or the like. At least one tubular hollow body 26 is inserted in the filling container 20, the upper end of which is provided with a cross-section-covering shield 27. The tubular hollow body 26 is advantageously designed conically narrowing towards the bottom closure in order to provide the lowest possible resistance to the falling molding material mass 8. With the same function, the side walls 28 of the filling container 20 are also arranged towards the bottom closure 25, conically expanding the horizontal spatial cross section of the filling container 20. The tubular hollow body 26 is used approximately lying on the flaps 24 of the bottom closure 25, with which the most favorable possible outflow of the air displaced when the molding material mass is poured into the molding box 12 can be achieved.
Die innere Querschnittsfläche dieses Füllbehälters 20 ist hierbei annähernd gleich der Querschnittsfläche der zur Deckung bringbaren Kombination von Füllrahmen 11 und Formkasten 12 vorgesehen. Besonders bei grossvolumigen Formkombinationen ist es vorteilhaft, anstelle eines einzelnen rohrförmigen Hohlkörpers 26 mehrere solcher Hohlkörper 26a zu verwenden und diese im Räume des Füllbehälters 20 gezielt einzusetzen. Zweckmässig ist es hierbei, die rohrförmigen Hohlkörper 26a in Fallrichtung parallel zueinander anzuordnen. Dies schliesst jedoch nicht aus, auch Anordnungen zu wählen, bei welchen die rohrförmigen Hohlkörper 26a unterschiedliche Richtungen aufweisen. Ebenso ist es möglich die Wandungen der Hohlkörper 26, 26a perforiert auszubilden.The inner cross-sectional area of this filling container 20 is provided approximately equal to the cross-sectional area of the combination of filling frame 11 and molding box 12 which can be made to coincide. Particularly in the case of large-volume shape combinations, it is advantageous to use a plurality of such hollow bodies 26a instead of a single tubular hollow body 26 and to use them specifically in the spaces of the filling container 20. It is expedient here to arrange the tubular hollow bodies 26a parallel to one another in the direction of fall. However, this does not rule out selecting arrangements in which the tubular hollow bodies 26a have different directions. It is also possible to make the walls of the hollow bodies 26, 26a perforated.
Im Anwendungsbeispiel wird im Funktionsablauf eine erfindungs gemässe Einrichtung in einer Dosierstation "A" von einem Dosierband mit einer bestimmten Menge Formstoff beschickt und anschliessend in die Füllage "B" über die Formkombination von Füllrahmen 11, Formkasten 12 und Modellplatte 13 mit Modell 14 gebracht. Durch Betätigen eines in einem Hubzylinder 15 eingesetzten Hubkolbens 16 wird die auf einer Platte 17 aufgesetzte Formkombination gegen die Fülleinrichtung 1, 9 bzw. 20 angehoben und mit dieser verbunden. Während des Hubvorganges wird zuerst der Formkasten 12 von, diesen tragenden Tragrollen 18 abgehoben und gegen den auf Auflagen 19 ruhenden Füllrahmen 11 geführt. Nach dem Verbinden der Fülleinrichtung 1, 9 bzw. 20 mit der Formkombination 11, 12, 13 werden die Klappen 6 bzw. 24 betätigt um den Bodenverschluss 5 bzw. 25 zu öffnen, so dass die Formstoffmasse 8 in die Formkombination 11, 12, 13 ausfHessen kann. Während des Ausfliessens der Formstoffmasse 8 kann die in der Formkombination 11, 12, 13 befindliche Luft einerseits durch den Querschnitt des Abstandes 10 zwischen Füllbehälter 1 und Behälterrahmen 9, andererseits durch die Hohlkörper 26, 26a ungehindert entweichen, ohne, dass hierbei Formstoffpartikel in die Umgebung gestossen werden.In the application example, a device according to the invention is loaded in the dosing station "A" from a dosing belt with a certain amount of molding material and then brought into the filling position "B" via the shape combination of filling frame 11, molding box 12 and model plate 13 with model 14 in the functional sequence. By actuating a lifting piston 16 inserted in a lifting cylinder 15, the shape combination placed on a plate 17 is raised against the filling device 1, 9 or 20 and connected to it. During the lifting process, the molding box 12 is first lifted off from these carrying rollers 18 and guided against the filling frame 11 resting on supports 19. After connecting the filling device 1, 9 or 20 to the mold combination 11, 12, 13, the flaps 6 or 24 are actuated to open the bottom closure 5 or 25, so that the molding material composition 8 into the mold combination 11, 12, 13 can measure. While the molding material mass 8 is flowing out, the air in the molding combination 11, 12, 13 can escape unhindered on the one hand through the cross section of the distance 10 between the filling container 1 and the container frame 9, and on the other hand through the hollow bodies 26, 26a, without any molding material particles being released into the environment be pushed.
Die Anwendung der beschriebenen Einrichtung ist nicht nur auf das Einfüllen von Giessereiformstoffen beschränkt, sondern kann überall dort eingesetzt werden wo körnige Stoffe in dosierter Menge in einen einseitig offenen Behälter gefüllt werden müssen. The application of the device described is not only limited to the filling of foundry mold materials, but can be used wherever granular materials in dosed amount must be filled in a container open on one side.
