Description

Die Erfindung bezieht sich auf eine Einrichtung zum Ausstreifen und Zusammendrücken des freien Überstandes über dem Fullgut von befüllten Säcken bei nach innen gefalteten Seitenwänden, mit zwei in der Ebene der Sacköffnung bzw. einer zu dieser parallelen Ebene, sowie in einer zu dieser senkrechten Ebene bewegbaren Paaren von in den geöffneten Sack eingreifenden Fingern, wobei die Finger eines jeden Paares in Querrichtung der Sacköffnung voneinander beabstandet sind, und mit zwei gegenläufig zueinander bewegbaren Stäben oder Schwertern, die von der Außenseite des Sackes her zwischen die Finger eines jeden Paares der in den Sack, gegebenenfalls zu beiden Seiten eines verschließbaren Fülltrichters einer Sackfülleinrichtung, eingreifenden Finger einschiebbar sind.The invention relates to a device for stripping and compressing the free excess over the full material of filled sacks with inwardly folded side walls, with two in the plane of the sack opening or a plane parallel to this, and in a pair movable to this vertical plane of fingers engaging in the opened sack, the fingers of each pair being spaced apart from one another in the transverse direction of the sack opening, and with two rods or swords which can be moved in opposite directions and which extend from the outside of the sack between the fingers of each pair of those in the sack, if necessary, engaging fingers can be inserted on both sides of a closable filling funnel of a bag filling device.

Bei bekannten derartigen Einrichtungen, wie in der GB-A-2038763 beschrieben und im Oberbegriff des Anspruches 1 berücksichtigt, werden die Finger eines jeden Paares von Fingern nach dem Einführen in die Sacköffnung gemeinsam gegen die Seitenwand des Sackes zu bewegt, wobei die beiden Paare von Fingern gegenläufgig bewegt werden. Dabei kommt es zu einem Ausspannen des Überstandes des befüllten Sackes, wonach dann die Schwerter zwischen die Finger eingeschoben werden und dadurch die nach innen gerichtete Falte in beiden Seitenwänden des Sackes hergestellt wird.In known devices of this type, as described in GB-A-2038763 and taken into account in the preamble of claim 1, the fingers of each pair of fingers are moved together against the side wall of the sack after insertion into the sack opening, the two pairs of Fingers are moved in opposite directions. This causes the protrusion of the filled sack to be stretched out, after which the swords are then inserted between the fingers, thereby producing the inward fold in both side walls of the sack.

Dabei ergibt sich jedoch der Nachteil, daß die Finger eines jeden Paares von Fingern in Querrrichtung der Sacköffnung bzw. in Richtung der Seitenwände des Sackes nur einen relativ geringen Abstand voneinander haben können um eine entsprechend starke Ausbildung der Falten der Seitenwände im überstand des Sackes sicherzustellen. Dadurch kann es aber vorkommen, daß eine Falte im Bereich des Überganges zu den gefalteten Seitenwändes des Sackes, insbesondere bei breiteren Säcken, nicht ordnungsgemäß ausgesteift wird und es beim anschließenden Zusammenpressen der Vorder- und Rückseite des Sacküberstandes zur Ausbildung von Quetschfalten kommt, die beim abschließenden Verschließen des Sackes, insbesondere wenn dies durch Vernähen oder Verschweißen erfolgt, erhebliche Probleme mit sich bringen.However, there is the disadvantage that the fingers of each pair of fingers in the transverse direction of the bag opening or in the direction of the side walls of the bag can only have a relatively small distance from one another in order to ensure a correspondingly strong formation of the folds of the side walls in the projection of the bag. However, this can result in a fold in the area of the transition to the folded side walls of the sack, in particular in the case of wider sacks, not being properly stiffened and in the subsequent pressing together of the front and back of the sack protrusion, which leads to the formation of pinch folds, which in the end Sealing the bag, especially if this is done by sewing or welding, can cause considerable problems.

Ziel der Erfindung ist es, diese Nachteile zu vermeiden und eine Einrichtung der eingangs erwähnten Art vorzuschlagen, bei der ein sicheres Ausstreifen des Sacküberstandes gewährleistet ist.The aim of the invention is to avoid these disadvantages and to propose a device of the type mentioned in the introduction, in which a secure stripping of the sack overhang is ensured.

Erfindungsgemäß wird dies dadurch erreicht, daß die Finger eines jeden Paares von in den Sack eingreifenden Fingern exzentrisch an gegenläufig verdrehbaren Scheiben angeordnet sind.According to the invention this is achieved in that the fingers of each pair of fingers engaging in the bag are arranged eccentrically on disks which can be rotated in opposite directions.

Durch diese Maßnahmen ist es möglich, die Finger im Bereich der Ecken der Sacköffnung in diese eingreifen zu lassen und durch entsprechendes Verdrehen der Finger den Sack im gesamten Eckbereich der Sacköffnung auszustreifen, so daß sämtliche Falten sicher geglättet werden.These measures make it possible for the fingers to engage in the corners of the sack opening and to strip out the sack in the entire corner area of the sack opening by turning the fingers accordingly, so that all folds are reliably smoothed out.

Nach einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, daß die in den Sack eingreifenden Finger aus gegebenenfalls dreieckig zugeschnittenen dünnen Platten oder Blechen gebildet sind.According to a further embodiment of the invention, it can be provided that the fingers engaging in the sack are formed from thin plates or sheets which may be cut into triangles.

Dies ermöglicht es, in Verbindung mit der Verdrehung der Finger, die Vorder- und Rückseite des zu verschließenden Sackes allein schon durch die Bewegung der Finger einander sehr stark anzunähern und in eine für das endgültige Verschließen sehr günstige Lage zu bringen, wobei während der Herstellung der Falten in den Querwänden eine exakte Führung der Wände des Sackes durch die Finger gegeben ist.This makes it possible, in connection with the twisting of the fingers, to bring the front and back of the sack to be closed very close to one another simply by the movement of the fingers and to bring them into a position which is very favorable for the final closing, while the Folding in the transverse walls gives an exact guidance of the walls of the sack by the fingers.

Bei einer bevorzugten Ausführungsform der Erfindung kann vorgesehen sein, daß jeder in einen Sack eingreifende Finger um einen Winkel von mehr als 180°, vorzugsweise um einen Winkel von 270° drehbar ist, wobei in der Endstellung die Finger eines Paares zueinander parallel stehen und den minimalen Abstand voneinander aufweisen.In a preferred embodiment of the invention it can be provided that each finger engaging in a sack can be rotated through an angle of more than 180 °, preferably through an angle of 270 °, the fingers of a pair being parallel to one another in the end position and the minimum Have a distance from each other.

Dies ermöglicht es, die Finger eines jeden Paares so zu bewegen, daß diese im Zuge der Drehung der sie haltenden Scheiben, zuerst ihren gegenseitigen Abstand in Querrichtung der Sacköffnung vergrößern und dadurch den Sack ausspannen und anschließend eine Endstellung einnehmen, in der die Finger eines jeden Paares von Fingern einen Abstand einnehmen, der ausreicht, um die Schwerter bequem zwischen die Finger einschieben zu können, wobei die Seitenwände in Falten gelegt werden und die Vorder- und Rückseite des Sackes einander stark angenähert werden. Dies ermöglicht es auch, das freie Ende des Sacküberstandes mit einsprechenden Klemmeinrichtungen zu erfassen, wonach der Sack durch Vernähen oder Verschweißen verschlossen werden kann.This makes it possible to move the fingers of each pair in such a way that, as the discs holding them rotate, first increase their mutual distance in the transverse direction of the sack opening and thereby unclamp the sack and then assume an end position in which the fingers of each pair of fingers are at a distance which is sufficient to be able to insert the swords comfortably between the fingers, the side walls wrinkled and the front and back of the sack are closely approximated. This also makes it possible to grasp the free end of the sack protrusion with corresponding clamping devices, after which the sack can be closed by sewing or welding.

Weiters kann vorgesehen sein, daß die die Finger eines Paares tragenden Scheiben drehfest mit Zahnrädern verbunden sind, die miteinander kämmen und von denen eines mit einem Antrieb verbunden ist.Furthermore, it can be provided that the disks carrying the fingers of a pair are connected in a rotationally fixed manner to gearwheels which mesh with one another and one of which is connected to a drive.

Damit wird auf einfache Weise eine schlupffreie Mitnahme der Finger in einander entgegengesetzten Drehrichtungen sichergestellt, wodurch auch ein sehr exakter Ablauf der Herstellung der Seitenfalten in den Querwänden des Überstandes eines befüllten Sackes und optimale Vorbereitung desselben zum endgültigen Verschließen gewahrleistet ist.This ensures a slip-free entrainment of the fingers in opposite directions of rotation, which also ensures a very precise production of the side gussets in the transverse walls of the overhang of a filled sack and optimal preparation of the same for final closure.

Bei einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß für den Antrieb der die Finger haltenden Scheiben bzw. der mit diesen drehfest verbundenen Zahnräder eine mit einem Druckmedium beaufschlagbare Zylinder-Kolbenanordnung vorgesehen ist.In a particularly preferred embodiment of the invention it is provided that a cylinder-piston arrangement which can be acted upon with a pressure medium is provided for driving the disks holding the fingers or the gears connected to them in a rotationally fixed manner.

Auf diese Weise kann die Beschleunigung der Finger sehr einfach an die jeweiligen Gegebenheiten angepaßt und damit eine entsprechende Schonung des Sackes erreicht werden.In this way, the acceleration of the fingers can be very easily adapted to the particular circumstances and the bag is protected accordingly.

Die Erfindung wird nun anhand der Zeichnung näher erläutert. Dabei zeigen:

  • Fig. 1 und 2 eine Sackfülleinrichtung mit einer erfindungsgemäßen Einrichtung, die in der linken Hälfte der Fig. 1 in Ruhe- und in der rechten Hälfte in einer in einen Sack eingreifenden Arbeitsstellung dargestellt ist, und
  • Fig. 3 bis 5 schematisch die erfindungsgemäße Einrichtung in verschiedenen Phasen des Bewegungsablaufes in Draufsicht.
The invention will now be explained in more detail with reference to the drawing. Show:
  • 1 and 2 a bag filling device with a device according to the invention, which in the left half of the Fig. 1 is shown in rest and in the right half in a working position engaging in a bag, and
  • Fig. 3 to 5 schematically, the device according to the invention in different phases of the movement in plan view.

In dem Gestell 1 der Sackfülleinrichtung ist in bekannter Weise ein verschließbarer Fülltrichter 2 mit Klemmeinrichtungen 3 samt den Sackspreizern 4 gehalten. Auf den Säulen 5 des Gestelles 1 ist ein Schlitten 6 verschiebbar gehalten, auf dem zwei Schwerter 7 schwenkbar gehalten sind, die über Zylinder-Kolbeneinrichtungen 8 bewegbar sind. Weiters sind an diesem Schlitten 6 Antriebe, die durch Zylinder-Kolbeneinrichtungen 12 gebildet sind, angeordnet, die zur Betätigung von in die Sacköffnung einführbaren Fingern 9, 9′ dienen.In the frame 1 of the bag filling device, a closable filling funnel 2 with clamping devices 3 together with the bag spreaders 4 is held in a known manner. On the columns 5 of the frame 1, a carriage 6 is slidably held, on which two swords 7 are pivotally held, which can be moved via cylinder-piston devices 8. Furthermore, 6 drives, which are formed by cylinder-piston devices 12, are arranged on this carriage, which serve to actuate fingers 9, 9 'which can be inserted into the bag opening.

Diese Finger 9, 9′ sind aus einer relativ dünnen Platte hergestellt und im wesentlichen dreieckig ausgebildet. Mit ihrem einen Ende sind diese Finger 9 an der Mantelfläche einer drehbar gehaltenen Scheibe 10 befestigt, wobei diese im Bereich der Verbindung mit dem Finger eine Abflachung 10′ aufweist.These fingers 9, 9 'are made of a relatively thin plate and essentially triangular. With one end, these fingers 9 are attached to the outer surface of a rotatably held disc 10, which has a flattening 10 'in the region of the connection with the finger.

Jede Scheibe 10 ist drehfest mit einem Zahnrad 11 verbunden, wobei die Zahnräder 11 eines Paares von Fingern 9 miteinander kämmen. Eines dieser Zahnräder 11 eines Paares von Fingern 9, 9′ kämmt mit einem Zahnsegment 14, an dem eine Zylinder-Kolbenanordnung 12 exzentrisch angreift, die an dem Schlitten 6 abgestützt ist.Each disc 10 is rotatably connected to a gear 11, the gears 11 of a pair of fingers 9 meshing with each other. One of these gears 11 of a pair of fingers 9, 9 'meshes with a toothed segment 14 on which a cylinder-piston arrangement 12 engages eccentrically, which is supported on the carriage 6.

Weiters ist an dem Gestell 1 noch eine Sack-Zuführeinrichtung 13 gehalten, die eine Zuführung der leeren Säcke von einem seitlich liegenden Stapel zum verschließbaren Fulltrichter 2 ermöglicht.Furthermore, a sack feed device 13 is also held on the frame 1, which enables the empty sacks to be fed from a laterally lying stack to the closable full hopper 2.

Wesentlich für die Erfindung sind die beiden Schwerter 7 und die beiden Paare von Fingern 9, 9′, die in der unteren Stellung des Schlittens 6 in den geöffneten Sack 15 im Bereich des über dem Füllgut gelegenen Überstandes des Sackes in diesen eingreifen.Essential to the invention are the two swords 7 and the two pairs of fingers 9, 9 ', which engage in the lower position of the carriage 6 in the open bag 15 in the region of the excess of the sack overlying the contents of the bag.

Nach dem Einführen der Paare von Fingern 9, 9′ in die Sacköffnung nehmen die Finger 9, 9′ und die Schwerter 7 die in der Fig. 3 gezeigte Stellung ein, wobei der Sack 15 noch von dem verchließbaren Fülltrichter 2 und der dieser zugeordneten Klemmeinrichtung 3 gehalten ist. Nach dem Einführen der Finger 9, 9′ in den Sack 15 wird die Klemmung zwischen dem verschließbaren Fülltrichter 2 und der Klemmeinrichtung 3 gelöst, und der gefüllte Sack fällt auf die nicht dargestellte Unterlage. Gleichzeitig werden die beiden Paare von Fingern 9 durch die Zylinder-Kolbenanordnungen 12 in gegenläufigen Richtungen verdreht, wobei die Schließung des verschließbaren Fülltrichters 2 eingeleitet wird.After the insertion of the pairs of fingers 9, 9 'into the bag opening, the fingers 9, 9' and the swords 7 assume the position shown in FIG. 3, the bag 15 still being closed by the lockable hopper 2 and the clamping device associated therewith 3 is held. After insertion of the fingers 9, 9 'in the bag 15, the clamping between the closable hopper 2 and the clamping device 3 is released, and the filled bag falls on the pad, not shown. At the same time, the two pairs of fingers 9 are rotated in opposite directions by the cylinder-piston arrangements 12, the closure of the closable filling funnel 2 being initiated.

Dabei werden die Finger 9, 9′ in Richtung zur Vorder- bzw. Rückwand des Sackes 15 gedreht und kommen mit diesen in Kontakt, wodurch allfällige Falten in den Wänden des Sackes ausgestreift werden. Gleichzeitig werden auch die beiden Schwerter 7 gegeneinander bewegt, und sie beginnen, die Falten der Seitenwände des Sackes einzudrücken, wie dies in der Fig. 4 dargestellt ist, die eine Zwischenstellung der Finger 9, 9′ und der Schwerter 7 zeigt.The fingers 9, 9 'are rotated in the direction of the front or rear wall of the bag 15 and come into contact with them, whereby any folds in the walls of the bag are stripped. At the same time, the two swords 7 are moved against each other, and they begin to press in the folds of the side walls of the bag, as shown in Fig. 4, which shows an intermediate position of the fingers 9, 9 'and the swords 7.

Während des Weiterdrehens der Finger 9, 9′ streifen diese an den Seitenwänden entlang, wobei die Schwerter 7 weiter gegeneinander bewegt werden und die Falten der Seitenwände weiter eindrücken. In der aus der Fig. 5 ersichtlichen Stellung sind die beiden Finger 9, 9′ eines jeden Paares parallel zueinander ausgerichtet und weisen den minimalen Abstand voneinander auf, wobei die Schwerter 7 zwischen die Finger 9, 9′ eines jeden Paares eingreifen.While turning the fingers 9, 9 'graze them along the side walls, the swords 7 are moved further against each other and press the folds of the side walls further. In the position shown in FIG. 5, the two fingers 9, 9 'of each pair are aligned parallel to one another and have the minimum distance from one another, the swords 7 engaging between the fingers 9, 9' of each pair.

Nach Erreichen der Endstellung der Finger 9, 9′ und Schwerter 7 wird der Schlitten 6 wieder hochgefahren und werdun die Schwerter und Finger in die Ausgangslage zurückgestellt.After reaching the end position of the fingers 9, 9 'and swords 7, the carriage 6 is raised again and the swords and fingers will be returned to the starting position.
