The filling chamber (4) is suspended in a flexible manner and with vibration-damping within the machine frame (1) so that no vibrations are transmitted to the machine frame (1), in particular the weighing device (16). <IMAGE>

Description

Die Erfindung betrifft eine Abfülleinrichtung zum Abfüllen von staubförmigem, pulverigem und/oder granuliertem Füllgut in Säcke, insbesondere eine Ventilsackfüllmaschine, mit einem Maschinengestell und daran angeordneter Füllgutkammer mit Druckluftfördereinrichtung zum Austrag des Füllguts in einen daran anschließbaren Sack und mit einer Wägeeinrichtung.The invention relates to a filling device for filling dusty, powdery and / or granulated filling material into bags, in particular a valve bag filling machine, with a machine frame and a filling material chamber arranged thereon with a compressed air conveying device for discharging the filling material into a sack that can be connected to it and with a weighing device.

Derartige Maschinen sind bekannt, beispielsweise unter den Typenbezeichnungen BVP... -EM von der Greif-Werk Maschinenfabrik GmbH hergestellte und vertriebene Brutto-Ventilsackfüllmaschinen. Solche Ventilsackfüllmaschinen dienen zum Abfüllen von pulverförmigem oder granuliertem Füllgut in Papier- und Kunststoffventilsäcke. Das Füllgut wird dabei zunächst in eine Füllgutkammer eingebracht aus der das Füllgut dann über ein Füllrohr in den Ventilsack mittels Druckluft gefördert wird. Die Kammer ist druckdicht abschließbar und weist in der Regel eine Anblasvorrichtung zum Austragen des Füllguts sowie weitere Druckluftvorrichtungen im Bereich der Kammerwände auf, mit denen der Austrag aus der Kammer verbessert wird. Der Ventilsack wird von einem Sackstuhl abgestützt, der an seiner Oberseite schwenkbar am Maschinengestell aufgehängt und an seiner Unterseite mit der Wägeeinrichtung verbunden ist, mit der auch während des Füllvorgangs das Sackgewicht ermittelt werden kann. Über die Wägeeinrichtung wird der Füllvorgang gesteuert.Such machines are known, for example under the type designations BVP ... -EM manufactured and sold by Greif-Werk Maschinenfabrik GmbH gross valve bag filling machines. Valve bag filling machines of this type are used for filling powdered or granulated filling material into paper and plastic valve bags. The filling material is first introduced into a filling material chamber from which the filling material is then conveyed into the valve bag by means of compressed air via a filling tube. The chamber can be closed in a pressure-tight manner and generally has a blowing device for discharging the filling material and further compressed air devices in the region of the chamber walls, with which the discharge from the chamber is improved. The valve sack is supported by a sack chair which is pivotally suspended on the top of the machine frame and is connected on the underside to the weighing device with which the bag weight can also be determined during the filling process. The filling process is controlled via the weighing device.

Der vorbeschriebene Maschinentyp hat sich zum Abfüllen zahlreicher Füllgüter bestens bewährt. Es gibt jedoch Füllgutarten, bei denen die hier ausschließlich zum Einsatz kommende bekannte Druckluftförderung an ihre technischen Grenzen stößt. Insbesondere bei schwierigen Schüttgütern kann dies dazu führen, daß sich beispielsweise der Füllvorgang erheblich verzögert, sich innerhalb der Füllkammer kein kontinuierlicher und gleichmäßiger Materialfluß entwickelt oder sich nicht die erforderliche enge Packungsdichte (luftarmes Befüllen) innerhalb des Sacks einstellt.The machine type described above has proven itself very well for filling numerous filling goods. However, there are types of filling material in which the known compressed air supply used here only reaches its technical limits. In particular with difficult bulk goods, this can lead to the filling process being delayed considerably, for example, no continuous and uniform material flow developing within the filling chamber or the required tight packing density (low-air filling) being established within the sack.

Ausgehend von dem einleitend genannten Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, eine Abfülleinrichtung der vorgenannten Art dahingehend zu verbessern, daß auch schwierige Schüttgüter unter weitgehender Vermeidung der vorerwähnten Schwierigkeiten abfüllbar sind.Starting from the prior art mentioned in the introduction, the invention is therefore based on the object of improving a filling device of the aforementioned type in such a way that even difficult bulk goods can be filled while largely avoiding the aforementioned difficulties.

Gemäß der Erfindung wird dies dadurch gelöst, daß die Füllgutkammer elastisch innerhalb des Maschinengestells aufgehängt und mit einer Vibrationseinrichtung versehen ist, mit der die Kammer in mechanische Schwingungen versetzbar ist. Dadurch, daß die Kammer in mechanische Schwingungen versetzbar ist, wird der Füllgutaustrag aus der Kammer erheblich verbessert, da neben der sonst üblichen ausschließlichen Druckluftförderung aufgrund des durch die Vibrationseinrichtung hervorgerufenen Rütteleffekts eine zusätzliche Gravitationsförderung erreicht wird. Der Rütteleffekt bewirkt zudem, daß das innerhalb der Kammer befindliche Schüttgut nicht verklumpt und in einem gleichmäßigen Massenstrom ausgetragen werden kann. Unterstützt wird dies in an sich bekannter Weise durch die Druckluftfördereinrichtung, die nach Bedarf auch eine Belüftung der Kammerwandungen, insbesondere im Auslaßbereich beinhaltet.According to the invention, this is achieved in that the product chamber is suspended elastically within the machine frame and is provided with a vibration device with which the chamber can be set into mechanical vibrations. The fact that the chamber can be set in mechanical vibrations, the filling material discharge from the chamber is considerably improved, since in addition to the otherwise usual exclusive compressed air delivery due to the vibrating effect caused by the vibration device, additional gravitational support is achieved. The vibrating effect also means that the bulk material inside the chamber cannot clump and can be discharged in a uniform mass flow. This is supported in a manner known per se by the compressed air delivery device, which, if necessary, also includes ventilation of the chamber walls, especially in the outlet area.

Hat man sich bislang stets bemüht, Schwingungen innerhalb des Systems zu vermeiden, insbesondere um die Funktion der Wägeeinrichtung nicht zu beeinträchtigen, so geht die vorliegende Erfindung einen völlig anderen Weg. Sie erzeugt bewußt mechanische Schwingungen, isoliert jedoch das Schwingungssystem, also die Füllkammer innerhalb des Maschinengestells durch entsprechende elastische Lagerung. Auf diese Weise wird die Fülleistung der Einrichtung erhöht, ohne die Wägeeinrichtung nachteilig zu beeinflussen.Until now, efforts have always been made to avoid vibrations within the system, in particular in order not to impair the function of the weighing device, the present invention takes a completely different approach. It deliberately generates mechanical vibrations, but isolates the vibration system, i.e. the filling chamber within the machine frame, by means of appropriate elastic bearings. In this way, the filling capacity of the device is increased without adversely affecting the weighing device.

Die Vibrationseinrichtung kann technisch einfach dadurch realisiert werden, daß an einer Kammerwand ein unwuchtiger Rotationsmotor befestigt wird. Zweckmäßigerweise wird dies ein drehzahlsteuerbarer Motor sein, wobei auch das Unwuchtgewicht veränderbar sein sollte. Dann kann nämlich je nach Erfordernissen sowohl die Schwingungsfrequenz als auch die Schwingungsamplitude entsprechend eingestellt werden. Grundsätzlich können diese Werte in weiten Bereichen variiert werden.The vibrating device can be realized technically simply by attaching an unbalanced rotary motor to a chamber wall. This will expediently be a speed-controllable motor, and the unbalance weight should also be changeable. Then, depending on the requirements, both the oscillation frequency and the oscillation amplitude can be set accordingly. In principle, these values can be varied over a wide range.

Bevorzugt wird die Vibrationseinrichtung an einer Kammerwand angebracht, die das Füllgut nach unten abstützt, so daß der Kontakt zwischen Füllgut und Kammerwand sichergestellt ist, denn gerade dann stellt sich der vorerwähnte positive Effekt ein.The vibration device is preferably attached to a chamber wall, which supports the filling material downwards, so that the contact between the filling material and the chamber wall is ensured, because precisely then the aforementioned positive effect occurs.

Bevorzugt wird die Füllgutkammer über Feder-Dämpfungselemente mit dem Maschinengestellt verbunden, so daß die Kammer möglichst weitgehend vom Maschinengestellt schwingungsisoliert ist und auf das Maschinengestell so wenig wie möglich Schwingungen übertragen werden.The product chamber is preferably connected to the machine frame by means of spring damping elements, so that the chamber is largely insulated from the machine frame as far as possible and vibrations are transmitted to the machine frame as little as possible.

Um auch während des Füllvorgangs eine zuverlässige Gewichtskontrolle und somit eine Steuerung des Füllvorgangs über die Wägeeinrichtung vornehmen zu können ist es wichtig, daß die Füllgutkammer nicht nur vom Maschinengestell, sondern auch von der Wägeeinrichtung schwingungsisoliert ist. Dies ist insbesondere dann ein Problem, wenn quasi im geschlossenen System gefüllt wird, d.h. ein Füllrohr der Abfülleinrichtung in den Sack hineinragt. Für diesen häufig anzutreffenden Fall sieht die Erfindung vor, zwischen Kammerauslaß und diesem Füllrohr einen schwingungsisolierenden Kanalabschnitt vorzusehen. Dies kann in einfacher Weise durch ein Schlauchstück, beispielsweise einen weichen Gummischlauch gebildet sein.In order to be able to carry out a reliable weight control and thus control of the filling process via the weighing device even during the filling process, it is important that the product chamber is not only vibration-isolated from the machine frame but also from the weighing device. This is particularly a problem when filling is practically in a closed system, i.e. a filling tube of the filling device protrudes into the sack. For this frequently encountered case, the invention provides for a vibration-isolating duct section to be provided between the chamber outlet and this filling tube. This can be formed in a simple manner by a piece of hose, for example a soft rubber hose.

Wenn eine geeignete Schwingungsisolierung zwischen Kammerauslaß und dem Füllrohr gebildet ist, kann das Füllrohr fest mit dem Sackstuhl verbunden sein, der bekanntlich Teil der Wägeeinrichtung ist. Insoweit kann dann auf bereits bekannte Konstruktionen zurückgegriffen werden, so daß auch weitgehend Baugruppen dieser bekannten Maschinen zum Einsatz kommen können.If a suitable vibration isolation is formed between the chamber outlet and the filling tube, the filling tube can be firmly connected to the bag chair, which is known to be part of the weighing device. To this extent, already known constructions can then be used, so that largely assemblies of these known machines can also be used.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels erläutert. Es zeigen:

The invention is explained below with reference to an embodiment shown in the drawing. Show it:
Figure 1
in a highly schematic representation, the side view of a valve bag filling machine and partially shown in section
Figure 2
a rear view of the machine shown in Figure 1.

Das Maschinengestell ist in den Figuren mit 1 gekennzeichnet. Es besteht im wesentlichen aus einem in seiner Außenkontur etwa quaderförmigen Rahmen, der aus vier vertikalen Holmen 2 und diese verbindenden horizontalen Holmen 3 aufgebaut ist. Innerhalb dieses Maschinengestells 1 ist eine Füllgutkammer 4 aufgehängt, die in der dargestellten Ausführung rechteckigen Querschnitt hat und deren Wände zu ihrem nach unten und vorne gerichteten Auslaß 5 schräg zulaufen. Das Einfüllen des Füllguts in die Füllgutkammer erfolgt über den an der Oberseite angeordneten Einlaß 6, der in gleicher Weise wie der Auslaß über ein Ventil absperrbar ist. Im Bereich des Einlasses 6 wird dieses Ventil in der Regel durch ein Kegel oder Drehklappenventil gebildet. In der dargestellten Ausführungsform ist der Einlaß 6 über ein Drehklappenventil 7 absperrbar.The machine frame is identified by 1 in the figures. It essentially consists of a frame which is approximately cuboid in its outer contour and which consists of four vertical bars 2 and these connecting horizontal bars 3 is constructed. A filling chamber 4 is suspended within this machine frame 1, which in the embodiment shown has a rectangular cross section and the walls of which taper obliquely to its downward and forward outlet 5. The filling material is filled into the filling material chamber via the inlet 6 arranged at the top, which can be shut off via a valve in the same way as the outlet. In the area of the inlet 6, this valve is generally formed by a cone or rotary flap valve. In the embodiment shown, the inlet 6 can be shut off via a rotary flap valve 7.

Das Auslaßventil ist nicht im einzelnen dargestellt, ebenso nicht die Schüttgutblasvorrichtung, also die Druckluftfördereinrichtung der Maschine. Diese ist in an sich bekannter Weise ausgebildet und braucht daher hier nicht beschrieben zu werden. In Figur 1 ist beispielhaft eine Unterlufteinrichtung 8 für den unteren Kammerboden dargestellt. Es versteht sich, daß derartige Einrichtungen auch in anderen Kammerwänden vorgesehen sein können, wie dies beim einleitend geschilderten Stand der Technik ebenfalls vorgesehen sein kann.The outlet valve is not shown in detail, nor is the bulk material blowing device, that is to say the compressed air delivery device of the machine. This is designed in a manner known per se and therefore need not be described here. In FIG. 1, an under-air device 8 for the lower chamber floor is shown as an example. It is understood that such devices can also be provided in other chamber walls, as can also be provided in the prior art described in the introduction.

Die Füllgutkammer 4 ist über federelastische Dämpfungselemente 9 an der Oberseite des Maschinengestells 1 aufgehängt, so daß mechanische Schwingungen der Füllgutkammer 4 nicht auf das Maschinengestell 1 übertragen werden. Bei der dargestellten Ausführung sind hierzu vier Feder- und Dämpfungselemente 9 vorgesehen, die jeweils im Bereich der oberen Eckpunkte des Maschinengestells 1 gelagert sind.The product chamber 4 is suspended via spring-elastic damping elements 9 on the upper side of the machine frame 1, so that mechanical vibrations of the product chamber 4 are not transmitted to the machine frame 1. In the embodiment shown, four spring and damping elements 9 are provided for this purpose, each of which is mounted in the area of the upper corner points of the machine frame 1.

An der nach hinten und unten weisenden Kammerwand 10 ist ein Elektromotor 11 angebracht, der eine bewußt erzeugte Unwucht aufweist, um so im Betrieb Schwingungen zu erzeugen und auf die Kammerwand 10 zu übertragen. Sämtliche Versorgungsleitungen, insbesondere die pneumatischen Leitungen, die zur Füllgutkammer 4 und deren Aggregate führen, sind elastisch aufgehängt, so daß keine nennenswerte Schwingungsübertragung auf die mit dem Maschinengestell 1 verbundenen Aggregate erfolgt.On the rearward and downward facing chamber wall 10, an electric motor 11 is attached, which has a consciously generated unbalance, so as to generate vibrations during operation and on the To transfer chamber wall 10. All supply lines, in particular the pneumatic lines that lead to the filling chamber 4 and its aggregates, are suspended elastically, so that no significant vibration is transmitted to the aggregates connected to the machine frame 1.

Die Füllgutkammer 4 kann auch im unteren Bereich elastisch dämpfend innerhalb des Maschinengestells 1 abgestützt sein. In der vorliegenden Ausführungsform ist dies nicht der Fall. Der Auslaß 5 der Füllgutkammer 4 ist über einen elastischen Schlauch 12 mit einem Füllrohr 13 verbunden, das wiederum fest mit einem vertikalen Träger 4 verbunden ist, der den Sackstuhl 15 trägt und Teil der (nicht im einzelnen dargestellten) Wägeeinrichtung 16 bildet. Über den Schlauch 12 wird das Füllrohr 13 gegenüber dem Auslaß 5 schwingungsisoliert. Die Wägeeinrichtung 16 ist somit wirkungsvoll schwingungsisoliert und ist in an sich bekannter Weise mit dem Maschinengestell 1 verbunden. Sie dient auch zur Steuerung des Füllvorgangs.The filling chamber 4 can also be supported in the lower region in an elastically damping manner within the machine frame 1. In the present embodiment, this is not the case. The outlet 5 of the product chamber 4 is connected via an elastic hose 12 to a filling tube 13, which in turn is firmly connected to a vertical support 4, which supports the bag chair 15 and forms part of the weighing device 16 (not shown in detail). The filling pipe 13 is vibration-isolated from the outlet 5 via the hose 12. The weighing device 16 is thus effectively vibration-isolated and is connected to the machine frame 1 in a manner known per se. It also serves to control the filling process.

Bezüglich der hier nicht im einzelnen beschriebenen an sich bekannten Konstruktionsdetails wird auf die einleitend zum Stand der Technik erwähnten Maschinen verwiesen.With regard to the construction details known per se, which are not described in detail here, reference is made to the machines mentioned in the introduction to the prior art.
