Definitions
- the invention relates to a bag filling machine with an electronic weighing device, which has a force transducer acted upon by a bag chair column, and with a bag chair guide, which consists of two upper and lower parallel bars, which are arranged on both sides of the bag chair column and whose two bearing points are designed as rod ends.
- Such a bag filling machine is known from DE-PS 27 04 138.
- links with rod ends for example self-aligning ball bearings
- certain manufacturing tolerances in the manufacture of the links can be compensated.
- D a for an electronic scale the displacement of the bag chair is only a few millimeters, is given a sufficiently good approximation to a vertical movement of the bag chair column.
- wishbones are provided, which engage the sack chair column in the upper and lower area and prevent a possible tilting movement.
- the wishbones Since the wishbones have a fixed length, they hinder somewhat the vertical movement of the sack chair column, as made possible by the parallel brackets. This can adversely affect the weighing process.
- the invention is therefore based on the object of designing a sack filling machine of the type mentioned at the outset in such a way that a tilting movement of the sack chair column between the parallel cores is reliably prevented and yet there is no impairment of the vertical movement of the sack chair column.
- Sack filling machines which are provided for filling valve sacks have a filling tube which can be inserted into the sack valve.
- the filling tube is regularly inclined downwards, for example by 20 ° with respect to the horizontal. It has been shown that a measurement error occurs during the filling process, during which the weighing process takes place continuously. Studies have shown that this measurement error is due to the fact that the filling material coming from the filling tube hits the side wall of the sack at approximately the angle of the filling tube. This creates a vertical force component that falsifies the weighing result.
- the parallel bars are ker parallel to an inclined filling tube.
- the parallel links are also inclined downwards at an angle of 20 °.
- the force transducer can still be aligned horizontally so that its measuring direction is aligned perpendicular.
- the force transducer can also be oriented in such a way that its measuring direction is oriented perpendicular to the parallel core, so that in the example mentioned it is tilted 20 ° from the vertical. This leads to the sensor measuring only one weight component, namely the weight multiplied by cos 20 °. To get the exact measurement result, the electronics of the balance must multiply the measurement result by 1 / cos 20 °.
- a fixed machine frame 1 is shown in broken lines. At the rear end of the machine frame 1 connected to pin 2 are formed as a spherical bearing G elenkkexcellent 3 of upper parallel links 4 and lower parallel links 5 is attached. The other ends of the parallel links are connected to an upper axle 6 or lower axle 7 via corresponding joint heads 3. In the middle of the axes 6, 7, sleeves 8 are arranged, which enclose a bag chair column 9 and hold it firmly.
- the upper parallel link 4 are connected by a rigid coupling rod 10 and the lower parallel link 5 by a rigid coupling rod 11.
- the coupling rod 10 or 11 thus forms a rigid frame with the associated parallel link core 4 or 5, which prevents the axes 6, 7 from tilting sideways out of the plane formed by the parallel link 4 or 5. This also prevents the bag chair column 9 from tilting.
- the parallel links 4,5 are inclined 20 ° downward from the horizontal. This inclination corresponds to the inclination of the filling tube (not shown) of the bag filling machine.
- this has a rectangular frame 12, the upper cross bar of which is connected to a force transducer 13.
- the frame 12 is inclined forwards from the vertical by 20 ° so that it is perpendicular to the planes formed by the parallel links 4 and 5, respectively.
- the force transducer 13 is oriented such that its effective measuring direction is oriented perpendicular to the links 4 and 5 - and thus also perpendicular to the upper crossbar of the frame 12.
- the force transducer 13 is formed by a bending rod, which is attached to the machine frame 1 parallel to the parallel core 4 or 5.
- the parallel links 4 and 5 are parallel to the filling tube of the bag filling machine and parallel to the longitudinal axis of the bending rod serving as a force transducer 13.
- the force transducer 13 does not measure the weight G of the filled bag, but a weight component G cos 20 °.
- the evaluation electronics is therefore set so that it multiplies the weight measured by the force transducer 13 by the constant factor 1 / cos 20 °. In this way, the correct absolute value is determined by the weighing device.

Abstract
Description
Die Erfindung betrifft eine Sackfüllmaschine mit einer elektronischen Wägeeinrichtung, die einen von einer Sackstuhlsäule beaufschlagten Kraftaufnehmer aufweist,und mit einer Sackstuhlführung, die aus je zwei oberen und unteren Parallellenkern besteht, die jeweils beidseitig der Sackstuhlsäule angeordnet sind und deren beide Lagerstellen als Gelenkköpfe ausgebildet sind.The invention relates to a bag filling machine with an electronic weighing device, which has a force transducer acted upon by a bag chair column, and with a bag chair guide, which consists of two upper and lower parallel bars, which are arranged on both sides of the bag chair column and whose two bearing points are designed as rod ends.
Eine derartige Sackfüllmaschine ist durch die DE-PS 27 04 138 bekannt. Durch die Verwendung von Lenkern mit Gelenkköpfen, beispielsweise Pendelkugellagern, können gewisse Fertigungstoleranzen bei der Herstellung der Lenker kompensiert werden. Da bei einer Elektronikwaage die Auslenkung des Sackstuhls nur wenige Millimeter beträgt, ist eine ausreichend gute Annäherung an eine lotrechte Bewegung der Sackstuhlsäule gegeben. Zur Vermeidung einer Kippbewegung der Sackstuhlsäule zwischen den Parallellenkern sind Querlenker vorgesehen, die im oberen und unteren Bereich der Sackstuhlsäule an dieser angreifen und eine eventuelle Kippbewegung verhindern.Such a bag filling machine is known from DE-PS 27 04 138. By using links with rod ends, for example self-aligning ball bearings, certain manufacturing tolerances in the manufacture of the links can be compensated. D a for an electronic scale, the displacement of the bag chair is only a few millimeters, is given a sufficiently good approximation to a vertical movement of the bag chair column. To avoid a tilting movement of the sack chair column between the parallel links, wishbones are provided, which engage the sack chair column in the upper and lower area and prevent a possible tilting movement.
Da die Querlenker eine feste Länge aufweisen, behindern sie etwas die vertikale Bewegung der Sackstuhlsäule, wie sie von den Parallellenkern ermöglicht wird. Hierdurch kann es zu einer Beeinträchtigung des Wägevorganges kommen. Since the wishbones have a fixed length, they hinder somewhat the vertical movement of the sack chair column, as made possible by the parallel brackets. This can adversely affect the weighing process.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Sackfüllmaschine der eingangs erwähnten Art so auszubilden, daß eine Kippbewegung der Sackstuhlsäule zwischen den Parallellenkern sicher verhindert wird und dennoch keine Beeinträchtigung der Vertikalbewegung der Sackstuhlsäule erfolgt.The invention is therefore based on the object of designing a sack filling machine of the type mentioned at the outset in such a way that a tilting movement of the sack chair column between the parallel cores is reliably prevented and yet there is no impairment of the vertical movement of the sack chair column.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeweils die oberen und unteren Parallellenker durch eine Koppelstange starr miteinander verbunden sind.This object is achieved in that the upper and lower parallel links are rigidly connected to each other by a coupling rod.
Durch diese überraschend einfache Maßnahme gelingt es, die Vorteile der Kompensation von Fertigungsungenauigkeiten durch die Gelenkköpfe beizubehalten und dennoch eine seitliche Kippbewegung sicher zu verhindern. Dabei bleibt die Vertikalbewegung der Sackstuhlsäule nach Wegfall der Querlenker völlig ungestört.By this surprisingly simple measure succeeds, the benefits of the compensation of manufacturing inaccuracies by the G elenkköpfe maintain and yet to prevent lateral tilting safe. The vertical movement of the sack chair column remains completely undisturbed after the wishbones are removed.
Sackfüllmaschinen, die zur Befüllung von Ventilsäcken vorgesehen sind, weisen eine in das Sackventil einführbare Füllröhre auf. Zum Zwecke der möglichst vollständigen Entleerung der Füllröhre nach dem Befüllvorgang für den einzelnen Sack ist die Füllröhre regelmäßig schräg nach unten geneigt, beispielsweise um 20° gegenüber der Horizontalen. Es hat sich gezeigt, daß beim Füllvorgang, währenddessen der Wägevorgang kontinuierlich stattfindet, ein Meßfehler entsteht. Untersuchungen haben ergeben, daß dieser Meßfehler darauf zurückzuführen ist, daß das Füllgut aus der Füllröhre kommend unter etwa dem Winkel der Füllröhre gegen die Seitenwand des Sackes prallt. Dabei wird eine lotrechte Kraftkomponente erzeugt, die das Wägeergebnis verfälscht.Sack filling machines which are provided for filling valve sacks have a filling tube which can be inserted into the sack valve. For the purpose of emptying the filling tube for the individual sack as completely as possible after the filling process, the filling tube is regularly inclined downwards, for example by 20 ° with respect to the horizontal. It has been shown that a measurement error occurs during the filling process, during which the weighing process takes place continuously. Studies have shown that this measurement error is due to the fact that the filling material coming from the filling tube hits the side wall of the sack at approximately the angle of the filling tube. This creates a vertical force component that falsifies the weighing result.
In einer bevorzugten Ausführungsform stehen die Parallellenker parallel zu einer schrägstehenden Füllröhre. In dem Beispiel der um 20° nach unten geneigten Füllröhre stehen somit auch die Parallellenker in einem Winkel von 20° nach unten geneigt. Dabei kann der Kraftaufnehmer dennoch horizontal ausgerichtet sein, so daß seine Meßrichtung lotrecht ausgerichtet ist.In a preferred embodiment, the parallel bars are ker parallel to an inclined filling tube. In the example of the filling tube inclined downwards by 20 °, the parallel links are also inclined downwards at an angle of 20 °. The force transducer can still be aligned horizontally so that its measuring direction is aligned perpendicular.
In einer weiteren Ausführungsform kann der Kraftaufnehmer jedoch auch so ausgerichtet sein, daß seine Meßrichtung senkrecht zu den Parallellenkern ausgerichtet ist, somit in dem genannten Beispiel um 20° aus der Lotrechten gekippt ist. Dies führt dazu, daß der Meßaufnehmer nur eine Gewichtskomponente mißt, nämlich das Gewicht multipliziert mit cos 20°. Um zu dem exakten Meßergebnis zu kommen, muß die Elektronik der Waage das Meßergebnis mit 1/cos 20° multiplizieren.In a further embodiment, however, the force transducer can also be oriented in such a way that its measuring direction is oriented perpendicular to the parallel core, so that in the example mentioned it is tilted 20 ° from the vertical. This leads to the sensor measuring only one weight component, namely the weight multiplied by cos 20 °. To get the exact measurement result, the electronics of the balance must multiply the measurement result by 1 / cos 20 °.
Durch die schräggestellten Parallellenker erzeugt das während der Befüllung auf die Seitenwand aufprallende Füllgut nun eine Kraft, die in Richtung der Längsachse der Parallellenker gerichtet ist. Diese Kraft beeinflußt daher den wägevorgang nicht. In dieser Ausführungsform läßt sich eine außerordentlich gute reproduzierbare Meßgenauigkeit erreichen. Die ggfs. notwendige Multiplikation mit 1/cos 20° durch die Elektronik stellt kein Problem dar.Due to the inclined parallel links, the filling material hitting the side wall during filling now generates a force that is directed in the direction of the longitudinal axis of the parallel links. This force therefore does not affect the weighing process. In this embodiment, extremely good reproducible measurement accuracy can be achieved. The necessary multiplication by 1 / cos 20 ° by the electronics is not a problem.
Die Erfindung soll im folgenden anhand eines in der Zeichnung dargestellten-Ausführungsbeispiels näher erläutert werden.The invention will be explained below with reference to an embodiment shown in the drawing.
In der Zeichnung ist ein fester Maschinenrahmen 1 gestrichel dargestellt. An mit dem hinteren Ende des Maschinenrahmens 1 verbundenen Zapfen 2 sind als Pendelkugellager ausgebildete Gelenkköpfe 3 von oberen Parallellenkern 4 und unteren Parallellenkern 5 angebracht. Die anderen Enden der Parallellenker sind über entsprechende Gelenkköpfe 3 mit einer oberen Achse 6 bzw. unteren Achse 7 verbunden. In der Mitte der Achsen 6,7 sind Hülsen 8 angeordnet, die eine Sackstuhlsäule 9 umschließen und fest halten. Die oberen Parallellenker 4 sind durch eine starre Koppelstange 10 und die unteren Parallellenker 5 durch eine starre Koppelstange 11 miteinander verbunden. Die Koppelstange 10 bzw. 11 bildet mit den zugehörigen Parallellenkern 4 bzw. 5 somit einen starren Rahmen, der ein seitliches Kippen der Achsen 6,7 aus der durch die Parallellenker 4 bzw. 5 gebildeten Ebene heraus verhindert. Somit wird auch ein Kippen der Sackstuhlsäule 9 verhindert.In the drawing, a fixed machine frame 1 is shown in broken lines. At the rear end of the machine frame 1 connected to
In dem dargestellten Ausführungsbeispiel sind die Parallellenker 4,5 um 20° nach unten aus der Horizontalen geneigt. Diese Neigung entspricht der Neigung der (nicht dargestellten) Füllröhre der Sackfüllmaschine. Am oberen Ende der Sackstuhlsäule 9 weist diese einen rechteckigen Rahmen 12 auf, dessen oberer Querbalken mit einem Kraftaufnehmer 13 verbunden ist. Der Rahmen 12 ist aus der Vertikalen um 20° nach vorn geneigt, so daß er senkrecht zu der durch die Parallellenker 4 bzw. 5 gebildeten Ebenen steht.In the illustrated embodiment, the
Der Kraftaufnehmer 13 ist so ausgerichtet, daß seine wirksame Meßrichtung senkrecht zu den Lenkern 4 bzw. 5 - und somit auch senkrecht zu dem oberen Querbalken des Rahmens 12 - ausgerichtet ist. In dem dargestellten Ausführungsbeispiel ist der Kraftaufnehmer 13 durch einen Biegestab gebildet, der parallel zu den Parallellenkern 4 bzw. 5 an dem Maschinenrahmen 1 befestigt ist.The
Somit ergibt sich, daß in dem dargestellten Ausführungsbeispiel die Parallellenker 4 bzw. 5 parallel zu der Füllröhre der Sackfüllmaschine und parallel zur Längsachse des als Kraftaufnehmer 13 dienenden Biegestabs stehen.It follows that in the illustrated embodiment, the
Es ist ohne weiteres ersichtlich, daß bei dieser Anordnung der Kraftaufnehmer 13 nicht das Gewicht G des gefüllten Sackes, sondern eine Gewichtskomponente G cos 20° mißt. Die Auswertungselektronik wird daher so eingestellt, daß sie das von dem Kraftaufnehmer 13 gemessene Gewicht mit dem konstanten Faktor 1/cos 20° multipliziert. Auf diese Weise wird der richtige Absolutwert durch die Wägeeinrichtung ermittelt.It is readily apparent that in this arrangement the
