Description

Die Erfindung betrifft eine Fülleinrichtung für Säcke, insbesondere Seitenfaltensäcke aus Papier, mit einem in den geöffneten Sack einfahrbaren Füllstutzen, mit Klemmeinrichtung zum Andrücken der' Innenseiten der Säcke an die Außenseiten des Füllstutzens.The invention relates to a filling device for bags, in particular gusseted bags made of paper, with a filler neck that can be moved into the open bag, with a clamping device for pressing the ' inside of the bags against the outside of the filler neck.

Die Fülleinrichtungen dieser Art werden in unterschiedlichen Ausführungsformen bereits seit längerem für das Abfüllen von staubigen Gütern verwendet. Solche Fülleinrichtungen werden dabei jeweils für einen bestimmten Papiersackquerschnitt ausgelegt. Dies hat zur Folge, daß der Verwender der Füllanlage jeweils auf einen bestimmten Sackquerschnitt mit vorgegebener Länge und Breite festgelegt ist.The filling devices of this type have been used in different embodiments for a long time for the filling of dusty goods. Such filling devices are each designed for a specific paper bag cross section. The consequence of this is that the user of the filling system is in each case fixed to a specific sack cross section with a predetermined length and width.

Der Erfindung liegt die Aufgabe zugrunde, eine Fülleinrichtung der als bekannt vorausgesetzten Art so auszubilden, daß sie auch für unterschiedliche Sackquerschnitte vorzugsweise mit unterschiedlichen Querschnittsbreiten verwendbar ist.The invention is based on the object of designing a filling device of the type known to be known so that it can also be used for different sack cross sections, preferably with different cross section widths.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß dadurch, daß zumindest an einer Seite des Füllstutzens ein wahlweise einsetzbares, den Außenumfang des Füllstutzen vergrößerndes Beilagestück vorgesehen ist, das im eingesetzten Zustand mit seiner Innenseite an der Außenseite des Füllstutzens und mit seiner Außenseite an der Innenseite des Sacks anliegt, wobei die Klemmeinrichtung zum wahlweisen Andrücken der benachbarten Sackwand an die Außenseite des Beilagestücks oder des Füllstutzens ausgebildet ist.This object is achieved according to the invention in that, at least on one side of the filler neck, an optional insert piece is provided which enlarges the outer circumference of the filler neck, which in the inserted state rests with its inside on the outside of the filler neck and with its outside on the inside of the sack , wherein the clamping device is designed to selectively press the adjacent bag wall against the outside of the insert piece or the filler neck.

Eine derartige Fülleinrichtung erlaubt die Verwendung unterschiedlicher Säcke mit unterschiedlichen Querschnitten. Üblicherweise werden die Säcke in der Sackbreite, also im Bereich der Seitenfalten verändert. Durch die Wahl unterschiedlich großer Beilagestücke können entsprechend unterschiedliche Sackformate verarbeitet werden.Such a filling device allows the use of different bags with different cross sections. The sacks are usually changed in their sack width, i.e. in the area of the gussets. By choosing different sized inserts, different bag formats can be processed.

Es hat sich als zweckmäßig erwiesen, daß die Klemmeinrichtung zum Zentrum des Füllstutzens weisende elastische Dichtbereiche aufweist.It has proven to be expedient for the clamping device to have elastic sealing areas pointing towards the center of the filler neck.

Gemäß einem weiteren Vorschlag der Erfindung weist auch das Beilagestück zum Zentrum des Füllstutzens weisende elastische Dichtbereiche auf.According to a further proposal of the invention, the shim also has elastic sealing areas facing the center of the filler neck.

Dabei sind die elastischen Dichtbereiche zweckmäßigerweise horizontal verlaufende Dichtleisten.The elastic sealing areas are expediently horizontal sealing strips.

Als besonders vorteilhaft hat sich eine Ausführungsform erwiesen, bei der das Beilagestück um eine horizontale Achse schwenkbar am Füllstutzen gelagert ist. Bei dieser Ausführung kann das Beilagestück in äußerst einfacher Weise wahlweise eingeschwenkt und damit wirksam oder ausgeschwenkt und damit unwirksam sein.An embodiment has proven to be particularly advantageous in which the insert piece is pivotally mounted on the filler neck about a horizontal axis. In this embodiment, the insert piece can be swiveled in in an extremely simple manner and thus be effective or swiveled out and thus ineffective.

Schließlich wird erfindungsgemäß vorgeschlagen, daß das Beilagestück an einer der beiden Längsseiten des Füllstutzens vorgesehen ist. Bei einer solchen Ausführungsform sind die Abdichteinrichtungen der drei übrigen Seiten lageunveränderlich ebenso ausgebildet, wie bei den bisher bekannten, im Format nicht verstellbaren Füllanlagen.Finally, it is proposed according to the invention that the insert piece is provided on one of the two long sides of the filler neck. In such an embodiment, the sealing devices of the three remaining sides are designed to be unchangeable in position, as is the case with the previously known filling systems which are not adjustable in format.

Nachstehend wird eine bevorzugte Ausführungsform der Erfindung anhand der Zeichnung im einzelnen beschrieben. Es zeigen :

  • Figur 1 eine Seitenansicht auf die schematisch dargestellte Fülleinrichtung mit einem im Querschnitt rechteckigen Fülltrichter, gesehen von der schmalen Seite,
  • Figur 2 einen Schnitt entlang Ebene 11-11 gemäß Figur 1,
  • Figur 3 die Fülleinrichtung mit ausgeschwenktem Paßstück in einer zu Figur 1 analogen Seitenansicht,
  • Figur 4 einen Schnitt entlang Ebene IV-IV gemäß Figur 3.
A preferred embodiment of the invention is described in detail below with reference to the drawing. Show it :
  • FIG. 1 shows a side view of the schematically illustrated filling device with a filling funnel with a rectangular cross section, seen from the narrow side,
  • FIG. 2 shows a section along plane 11-11 according to FIG. 1,
  • FIG. 3 shows the filling device with the fitting swung out in a side view analogous to FIG. 1,
  • FIG. 4 shows a section along plane IV-IV according to FIG. 3.

Ein feststehendes inneres Füllrohr 1 wird an seinem unteren Ende von einem Füllstutzen 2 umgriffen, der in Richtung des Doppelpfeils 3 aufwärts und abwärts verfahrbar ist. Durch das feststehende Füllrohr 1 und den verfahrbaren Füllstutzen 2 wird das Füllgut in den Sack 8, der als Seitenfaltensack mit gestaffelter Verschlußklappe ausgebildet ist, eingefüllt.A fixed inner filler pipe 1 is gripped at its lower end by a filler neck 2, which can be moved up and down in the direction of the double arrow 3. The filling material is filled into the sack 8, which is designed as a gusseted sack with a staggered closure flap, through the fixed filling tube 1 and the movable filling nozzle 2.

Am Füllstutzen 2 ist um eine horizontale Achse 4 verschwenkbar an einem Halter 5 ein Beilagestück 6 angeordnet. Dieses Beilagestück 6 dient zur bei Bedarf erfolgenden Vergrößerung des Außenquerschnitts des Füllstutzens 2. Das Beilagestück 6 kann verwendet werden, wenn ein Sack mit einem größeren Querschnitt, im vorliegenden Fall mit einer größeren Breite verwendet werden soll, als er üblicherweise zum Format des Füllstutzens 2 paßt.On the filler neck 2, an insert 6 is arranged on a holder 5 so as to be pivotable about a horizontal axis 4. This insert 6 serves to enlarge the outer cross section of the filler neck 2 if necessary. The insert piece 6 can be used when a sack with a larger cross section, in the present case with a larger width, is to be used than it usually fits the format of the filler neck 2 .

Das Beilagestück 6 liegt im Zustand gemäß Figur 1 mit seiner Innenseite 6a an der Außenseite 2a des Füllstutzens 2 an. Eine dichtende Gummileiste 7 verhindert einen Staubaustritt zwischen dem unteren Ende des Füllstutzens 2 und der Innenseite 6a des Beilagestücks 6.In the state according to FIG. 1, the insert 6 lies with its inside 6a on the outside 2a of the filler neck 2. A sealing rubber strip 7 prevents dust from escaping between the lower end of the filler neck 2 and the inside 6a of the insert piece 6.

Der Sack 8 liegt an der gemäß Figur 1 linken Seite und an dem schmalen, die Seitenfalten aufweisenden Stirnseiten unmittelbar am Füllstutzen 2 an. Das Andrücken des Seitenfaltensacks unmittelbar an den Füllstutzen 2 erfolgt über die feststehende Gummileiste 19 sowie über die in einer horizontalen Ebene verschwenkbaren Klemmleisten 22 bzw. 22', die um vertikale Achsen 23 bzw. 23' verschwenkbar sind mit Hilfe von Gabelköpfen 24 und 24', die an den Enden von Kolbenstangen einer doppelseitig wirkenden Kolben-Zylinder-Einheit sitzen.The sack 8 lies directly on the filler neck 2 on the left side according to FIG. 1 and on the narrow end faces which have the side folds. The gusset bag is pressed directly onto the filler neck 2 via the fixed rubber strip 19 and via the clamping strips 22 and 22 'which can be pivoted in a horizontal plane and which can be pivoted about vertical axes 23 and 23' with the aid of fork heads 24 and 24 ', which sit at the ends of piston rods of a double-acting piston-cylinder unit.

Die Dichtung an der gemäß Figur 1 rechten langen Seite des Sacks erfolgt mit Hilfe des Klemmzylinders 21, der über die Gummileiste 20 den Sack 8 zwischen Cummiieiste 20 und äußerer Seite 6b des Beilagestücks 6 festklemmt.The seal on the long right side of the sack according to FIG. 1 takes place with the aid of the clamping cylinder 21, which clamps the sack 8 between the rubber strip 20 and the outer side 6b of the insert piece 6 via the rubber strip 20.

Die Kolben-Zylinder-Einheiten 15 und 16, die zu beiden Seiten des Füllstutzens 2 vorgesehen sind, betätigen über Kolbenstangen 13 und 14 um die Achsen 11 und 10a verschwenkbare Öffnungsgreifer 9 und 10. Die Öffnungsgreifer 9 und 10 ziehen die ensprechenden Sackbereiche gegen elastische Widerlager 17 und 18.The piston-cylinder units 15 and 16, which are provided on both sides of the filler neck 2, operate via piston rods 13 and 14, pivotable opening about the axes 11 and 10a grippers 9 and 10. The opening grippers 9 and 10 pull the corresponding bag areas against elastic abutments 17 and 18.

Bei der Darstellung gemäß Figur 3 ist das Beilagestück 6 aufwärts weggeschwenkt, so daß in dieser Position der Sack gefüllt wird, der dem Querschnitt des Füllstutzens entspricht.In the illustration according to FIG. 3, the insert piece 6 is pivoted away upward, so that in this position the sack is filled which corresponds to the cross section of the filler neck.

Es ist möglich, unterschiedliche Beilagestücke vorzusehen, um unter Beibehaltung eines vorgegebenen Füllstutzens 2 Säcke mit unterschiedlichen Querschnitten befüllen zu können.It is possible to provide different insert pieces in order to be able to fill 2 sacks with different cross sections while maintaining a given filler neck.

Die Klemmeinrichtung 20, 21 wird bei dem gezeigten Ausführungsbeispiel in zwei unterschiedliche Positionen verfahren, nämlich entweder in die in Figur 1 dargestellte Position für einen Sack größerer Breite oder in die in Figur 3 gezeigte Position für einen Sack geringerer Breite. Nachdem die Dichtleisten 19 und 20 in ihren Endpositionen liegen, wird der Füllstutzen 2, der an seinem unteren Ende konisch ausgebildet ist, abwärts bis zu seiner endgültigen Klemmposition gefahren. In dieser endgültigen Klemmposition drückt der konische Bereich des Füllstutzens 2 den Sack 8 gegen die elastisch ausgebildeten Klemmleisten 19 und 20. Danach kann das Einschwenken der seitlichen Klemmleisten 22 und 22' erfolgen.In the exemplary embodiment shown, the clamping device 20, 21 is moved into two different positions, namely either into the position shown in FIG. 1 for a sack of greater width or into the position shown in FIG. 3 for a sack of smaller width. After the sealing strips 19 and 20 are in their end positions, the filler neck 2, which is conical at its lower end, is moved down to its final clamping position. In this final clamping position, the conical region of the filler neck 2 presses the sack 8 against the elastically designed clamping strips 19 and 20. The lateral clamping strips 22 and 22 'can then be swiveled in.

Das Beilagestück 6 ist über einen lediglich in Figur 3 schematisch dargestellten Stellzylinder 30 in die Einsetzlage gemäß Figur 1 verschwenkbar.The insert 6 can be pivoted into the inserted position according to FIG. 1 by means of an actuating cylinder 30 which is only shown schematically in FIG. 3.

Durch eine Programmsteuerung, welche die verschiedenen Stellmotoren 21, 15, 16 und 30 beeinflußt, kann ein Formatwechsel programmgesteuert erfolgen. Es genügt also in diesem Fall eine einzige Verstellhandlung, beispielsweise ein Knopfdruck des Bedienungsmannes, um von dem laufenden Format auf das zweite mögliche Format umzustellen. Die Umstellung erfolgt also in allerkürzester Zeit und stellt praktisch keinen Aufwand dar.A program control, which influences the various servomotors 21, 15, 16 and 30, can be used to change the format in a program-controlled manner. In this case, a single adjustment action, for example the operator pressing a button, is sufficient to switch from the current format to the second possible format. The changeover takes place in the shortest possible time and is practically no effort.
