Description

Vorrichtung zum Absacken von Schüttgut Bagging device for bulk goods
Die Erfindung betrifft eine Vorrichtung zum Absacken von Schüttgut nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for bagging bulk goods according to the preamble of claim 1.
Es sind bereits Vorrichtungen zum Absacken von Schüttgut bekannt. In derartigen Absackanlagen werden aus Schlauchfolien gebildete Säcke einem Fülltrichter zugeführt, abgefüllt, verschlossen und auf ein Auslaufband abgeführt. Dem Fülltrichter ist ein Produktbehälter zugeordnet, in dem das abzufüllende Schüttgut aufgenommen ist. Üblicherweise ist zwischen dem Produktbehälter und dem Fülltrichter noch eine Waage angeordnet, über die die in den Sack abzufüllende Menge bestimmt wird. Im Bereich der Waage ist bei bekannten Absackanlagen eine Absaugung vorgesehen, die dazu dient, staubförmiges Schüttgut zusammen mit der umgebenden Luft abzusaugen und einem Staubfilter zuzuführen. Diese Staubfilter bestehen üblicherweise aus Tiefenfiltern, d.h. Faserfiltern, die häufig mehrlagig übereinander angeordnet sind.Devices for bagging bulk goods are already known. In bagging systems of this type, bags formed from tubular films are fed to a filling funnel, filled, sealed and discharged onto an outlet belt. A product container is assigned to the hopper, in which the bulk material to be filled is received. A scale is usually arranged between the product container and the filling funnel, by means of which the quantity to be filled into the sack is determined. In known weighing systems, suction is provided in the area of the scales, which serves to extract dust-like bulk material together with the surrounding air and to supply it to a dust filter. These dust filters usually consist of depth filters, i.e. Fiber filters that are often stacked on top of each other.
Da in derartigen Absackanlagen häufig das abzufüllende Schüttgut gewechselt wird, sammelt sich im Tiefenfilter unterschiedliches Material, so daß nach Abreini- gung des Staubfilters in der Regel kein sortenreines Material vorliegt, das den abzufüllenden Produkten wieder zugeführt werden könnte. Der beim regelmäßigen Abreinigen des Staubfilters gewonnene Feststoff muß bei den bekannten Absackanlagen daher regelmäßig verworfen werden.Since the bulk goods to be filled are often changed in such bagging systems, different materials collect in the depth filter, so that after cleaning dust filter there is usually no pure material that could be returned to the products to be filled. The solid obtained during regular cleaning of the dust filter must therefore be regularly discarded in the known bagging systems.
Aufgabe der Erfindung ist es, eine gattungsgemäße Absackanlage von Schüttgut derart weiterzubilden, daß der beim Absacken abgesaugte Schüttgutanteil zumindest zum großen Teil wiedergewonnen werden kann.The object of the invention is to develop a generic bagging system for bulk material in such a way that the bulk material portion sucked off during bagging can be recovered at least in large part.
Diese Aufgabe wird erfindungsgemäß durch die Kombination der Merkmale des Anspruchs 1 gelöst.This object is achieved by the combination of the features of claim 1.
Demnach ist bei einer Vorrichtung zum Absacken von Schüttgut mit einem Produktbehälter zur Aufnahme des Schüttgutes, einem Fülltrichter und einem Staubfilter dem Staubfilter ein Abscheider vorgeschaltet, der über eine Saugleitung mit dem Fülltrichter in Verbindung steht. Der Abscheider ist dann vorzugsweise über eine Förderleitung für das abgeschiedene Schüttgut mit dem Produktbehälter verbunden.Accordingly, in a device for bagging bulk goods with a product container for receiving the bulk goods, a filling funnel and a dust filter, a separator is connected upstream of the dust filter, which is connected to the filling funnel via a suction line. The separator is then preferably connected to the product container via a conveyor line for the separated bulk material.
Gemäß dieser Lösung wird der beim Abfüllen des Schüttguts im Bereich des Schüttrichters entstehende Staub gleich erfasst und über die Saugleitung einem Abscheider, der gemäß einer besonders vorteilhaften Ausgestaltung der Erfindung ein Zyklon sein kann, zugeführt. In dem Abscheider wird der gröbere Feststoffanteil abgeschieden, während der Feinstanteil mit der Luft dem Staubfilter zur Abscheidung in den darin enthaltenen Tiefenfiltern zugeführt wird. Das abgeschiedene Schüttgut wird aus dem Abscheider über eine Förderleitung zum Produktbehälter zurückgeführt, wo dieses sortenrein dem abzufüllenden Schüttgut zugegeben werden kann.According to this solution, the dust which arises during the filling of the bulk material in the area of the hopper is immediately detected and fed via the suction line to a separator, which according to a particularly advantageous embodiment of the invention can be a cyclone. The coarser solid content is separated in the separator, while the very fine content is fed with the air to the dust filter for separation in the depth filters contained therein. The separated bulk material is returned from the separator via a conveyor line to the product container, where it can be added to the bulk material to be filled.
Weitere Vorteile der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen. Einzelheiten und Vorteile der Erfindung ergeben sich weiterhin aus dem anhand der einzigen Figur im folgenden beschriebenen Ausführungsbeispiel.Further advantages of the invention result from the subclaims following the main claim. Details and advantages of the invention emerge continue from the exemplary embodiment described below with reference to the single figure.
In der Figur ist schematisch eine Absackanlage dargestellt.A bagging system is shown schematically in the figure.
Die Absackanlage, die konventionell aufgebaut ist, ist allgemein mit der Bezugszahl 10 versehen. Hier werden von einer Schlauchfolienrolle 12 in ansonsten nicht näher dargestellter Art und Weise Schläuche abgetrennt, die an einem Ende zugeschweißt werden, um so einen Sack zu bilden. Die entsprechenden Säcke werden unter einen Fülltrichter 14 zum Befüllen mit Schüttgut gehängt. Nach Befüllung werden die Säcke 18 in einer Schweißstation verschlossen und anschließend über ein Auslaufband 16 abgeführt. Der Fülltrichter 14 ist Bestandteil der Absackanlage 10. Über dem Fülltrichter ist ein Produktbehälter 22 zur Aufnahme des abzufüllenden Schüttgutes angeordnet. Von dort wird das Schüttgut über eine Waage 24 dem Fülltrichter zum Befüllen der jeweils hier nicht näher dargestellten Säcke 18 zugeführt.The bagging system, which is constructed conventionally, is generally provided with the reference number 10. Here, from a tubular film roll 12, hoses are separated in an otherwise not shown manner, which are welded closed at one end so as to form a sack. The corresponding sacks are hung under a hopper 14 for filling with bulk material. After filling, the bags 18 are closed in a welding station and then removed via an outlet belt 16. The filling funnel 14 is part of the bagging system 10. A product container 22 is arranged above the filling funnel for receiving the bulk material to be filled. From there, the bulk material is fed via a scale 24 to the filling funnel for filling the sacks 18, which are not shown in each case here.
Am Fülltrichter 14 ist eine Absaughaube 26 oberhalb des Bereiches zum Einhängen der Säcke 18 angeordnet. An der Absaughaube 26 schliessen Saugleitungen 28 und 30 an, die in eine gemeinsame Leitung 32 münden. Die Leitung 32 läuft tangential in einen Zyklon 34 ein, der an seinem unteren Ende einen Auffangbehälter 36 zur Aufnahme des abgeschiedenen Schüttgutes aufweist. Von diesem Auffangbehälter 36 führt eine Förderleitung 38 für das abgeschiedene Schüttgut zum Produktbehälter 22. Über diese Förderleitung kann das abgeschiedene Schüttgut dem Produktbehälter 22 sortenrein zugeführt werden.A suction hood 26 is arranged on the filling funnel 14 above the area for hanging the bags 18. Suction lines 28 and 30 connect to the suction hood 26 and open into a common line 32. The line 32 runs tangentially into a cyclone 34 which has at its lower end a collecting container 36 for receiving the separated bulk material. A conveying line 38 for the separated bulk material leads from this collecting container 36 to the product container 22. The separated bulk material can be supplied to the product container 22 by type via this conveying line.
Am oberen Ende des Zyklons 34 ist eine Saugleitung 39 angeschlossen, die die Förderluft und den nicht abgeschiedenen Feinanteil des Schüttguts einem Staubfilter 40 zuführt. Das Staubfilter ist auf der Bühne 20 über Füße 42 aufgeständert. Im Staubfilter sind mehrere Filterschichten übereinander angeordnet. Die gereinigte Luft strömt in Pfeilrichtung A aus dem Staubfilter, während der Feinanteil des Schüttgutes in den Filtermatten zurückgehalten wird. Zum Abreinigen der Filtermatten ist am Staubfilter 40 ein Rüttelmotor 44 angeordnet, der den gesamten Staubfilter in Rüttelbewegungen versetzt, so daß der abgeschiedene Staub teilweise in einen unterhalb des Staubfilters angeordneten Trichter 46 fällt, von dem dieses Abfallmaterial über einen Abfallmaterialauslaß 48 abgezogen werden kann. Da die Filtermatten des Staubfilters 40 nicht bei jedem Produktwechsel ausgetauscht werden sollen, ist es hier nicht zu vermeiden, daß beim Rütteln des Staubfilters 40 unterschiedliches Produkt in den Trichter 46 gelangt, so daß das hier abgezogene Material nicht dem Produktbehälter 22 zugeführt werden kann.At the upper end of the cyclone 34, a suction line 39 is connected, which feeds the conveying air and the non-separated fine fraction of the bulk material to a dust filter 40. The dust filter is raised on stage 20 via feet 42. Several filter layers are arranged one above the other in the dust filter. The cleaned air flows out of the dust filter in the direction of arrow A, while the fine fraction of the bulk material is retained in the filter mats. To clean the filter mats, a vibrating motor 44 is arranged on the dust filter 40, which causes the entire dust filter to vibrate so that the separated dust partially falls into a funnel 46 arranged below the dust filter, from which this waste material can be drawn off via a waste material outlet 48. Since the filter mats of the dust filter 40 are not to be exchanged every time the product is changed, it cannot be avoided here that when the dust filter 40 is shaken, different product gets into the funnel 46, so that the material removed here cannot be fed to the product container 22.
Im hier dargestellten Ausführungsbeispiel ist ein Zyklon 34 als Vorabscheider beschrieben. Je nach Produktspezifikation des Schüttgutes kommen aber auch andere Abscheider, wie Umlenksichter etc. als Vorabscheider in Frage. In the exemplary embodiment shown here, a cyclone 34 is described as a pre-separator. Depending on the product specification of the bulk material, other separators, such as deflection sifters etc., can also be used as pre-separators.
