Description

Die Erfindung betrifft eine Vorrichtung zum Befüllen und Verschließen einseitig offener, vorzugsweise mit Seitenfalten versehener, Säcke nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for filling and closing unilaterally open, preferably provided with gusseted, bags according to the preamble of claim 1.

Eine derartige Vorrichtung ist beispielsweise aus der EP 290 879 A2 oder der DE 93 01 355 U bekannt. Die dort vorbeschriebene Vorrichtung weist jeweils eine einen Füllstutzen aufweisende Füllstation zum Befüllen der Säcke beispielsweise mit Granulat oder staubförmigem Füllgut auf. Es sind jeweils verschiedene Greifer zum Antransport der leeren Säcke, Halten der Säcke in der Füllstation und zum Abtransport der befüllten Säcke in der Vorrichtung vorgesehen. Unterhalb der Füllstation ist ein Förderband zum Abstützen und zum Transport der befüllten Säcke von der Füllstation weg vorhanden. Dieses Förderband weist ein zumindest um zwei Umlenkrollen laufenden Trum auf. Zum Verdichtung des Füllgutes dient ein Rüttler, der Rüttelbleche umfasst, die sich von den Seitenkanten des Obertrums des Förderbandes in Richtung zu dessen Mitte erstrecken. Da die Bleche oberhalb des Obertrums angeordnet sind, ist zwischen den Blechen ausreichend Platz vorgesehen, so dass die auf dem Trum des Förderbandes angeordneten Stollen Bewegungsfreiheit genießen. Da ein solcher Rüttler daher nur auf die Außenbereiche des Sackes wirkt, kommt es nur zu einer sehr ungleichmäßigen Befüllung desselbigen.Such a device is known for example from EP 290 879 A2 or DE 93 01 355 U. The above-described device has in each case one filling station having a filling station for filling the bags, for example with granules or dusty filling material. There are provided in each case different grippers for transporting the empty bags, holding the bags in the filling station and for transporting the filled sacks in the device. Below the filling station there is a conveyor belt for supporting and transporting the filled sacks away from the filling station. This conveyor belt has a run around at least two pulleys. For compacting the contents serves a vibrator comprising Rüttelbleche extending from the side edges of the upper run of the conveyor belt towards the center. Since the sheets are arranged above the upper strand, sufficient space is provided between the sheets, so that the arranged on the run of the conveyor belt cleats enjoy freedom of movement. Since such a vibrator therefore acts only on the outer areas of the bag, it comes only to a very uneven filling desselbigen.

Bei den bekannten Vorrichtungen werden im einem Bereich vor der Füllstation an den von einer Vorratsrolle abgezogenen thermoplastischen Schlauch die Bodenschweißnähte angebracht. Wenn die Vorrichtung nun mit hoher Taktzahl betrieben wird, ist die Bodennaht zu dem Zeitpunkt, zu dem der Sack an die Füllstation übergeben wird und dort befüllt wird, noch nicht ausgekühlt und hat ihre Endfestigkeit noch nicht erlangt. Beim schlagartigen Befüllen des Sackes über den Fülltrichter und die damit schlagartige Beanspruchung der Bodennaht, kann diese, insbesondere in dem Bereich zwischen den Rüttelblechen, aufplatzen. Hierdurch kann es zu einem unerwünschten Stillstand der Maschine kommen.In the known devices, the bottom welds are attached in an area in front of the filling station to the withdrawn from a supply roll thermoplastic hose. When the device is now operated at a high number of cycles, the bottom seam at the time when the bag is transferred to the filling station and is filled there, has not yet cooled and has not yet reached its final strength. When suddenly filling the bag over the hopper and the sudden impact of the bottom seam, this can, especially in the area between the Rüttelblechen burst. This can lead to an undesirable stoppage of the machine.

Auch aus der EP 468 376 A1 ist bereits eine Einrichtung zum Befüllen von Säcken bekannt, bei der unterhalb der Befülleinrichtung ein Förderband angeordnet ist. Ein Teil dieses Förderbandes ist abschwenkbar. Auf diesem Teil ruht zunächst der leere Sack mit unten umgeschlagenem Ende auf, so dass die Naht beim ersten Befüllschuss nicht übermäßig belastet wird. Während des weiteren Befüllvorganges wird der unterhalb des Sackes befindliche Teil des Bandes nach unten abgeschwenkt, so dass sich der Boden ausbilden kann. Nachdem dies geschehen ist, schwenkt auch weiterhin dieser Teil des Bandes rhythmisch nach unten und nach oben, um das Füllgut zu verdichten. Hierdurch ergibt sich insbesondere bei Verwendung von dünnwandigem Sackmaterial der Nachteil, dass das Material im Bereich der oberen Haltezange sehr hoch belastet und gedehnt wird, so dass der Sack beschädigt werden kann. Ein weiterer Nachteil dieser Einrichtung ist darin zu sehen, dass relativ große Massen für den Rüttel- und Verdichtvorgang bewegt werden müssen.A device for filling sacks is also known from EP 468 376 A1, in which a conveyor belt is arranged below the filling device. Part of this conveyor belt can be swung off. On this part, the empty bag initially rests with the end turned down, so that the seam is not excessively loaded during the first filling shot. During the further filling process, the part of the band located below the bag is swiveled downwards, so that the bottom can form. After this is done, this part of the band continues to swing rhythmically down and up to condense the contents. This results in particular when using thin-walled bag material, the disadvantage that the material in the region of the upper holding forceps is charged and stretched very high, so that the bag can be damaged. Another disadvantage of this device is the fact that relatively large masses must be moved for the shaking and compacting process.

Aufgabe der Erfindung ist es, eine gattungsgemäße Vorrichtung zu schaffen, mit der sowohl eine einwandfreie Bodenausbildung während des Befüllvorgangs gewährleistet ist und zum anderen sichergestellt wird, dass eine einwandfreie Verdichtung erreicht werden kann, ohne große Massen zu bewegen.The object of the invention is to provide a generic device, with both a proper soil formation is ensured during the filling and on the other hand, it is ensured that proper compression can be achieved without moving large masses.

Erfindungsgemäß wird diese Aufgabe ausgehend von einer gattungsgemäßen Vorrichtung durch die zusätzlichen Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Demnach ist das Förderband im Bereich unterhalb der Füllstation durch Verschwenken der Umlenkrolle absenkbar und wieder anhebbar. Unter dem Obertrum des Förderbandes ist im Bereich der Füllstation zusätzlich ein Rüttler angeordnet. Durch diese Ausgestaltung des Förderbandes ist folgender schonender Befüllvorgang des in der Füllstation gehaltenen Sackes möglich. Zunächst wird der unbefüllte Sack mit der noch nicht ausgekühlten Bodennaht in die Füllstation eingehängt, wobei die Greifer der Füllstation den Sack an seinem offenen Ende ergreifen. Das verschlossene Ende des liegt dabei auf dem unterhalb der Füllstation angeordneten Obertrum des Förderbandes, wobei der Abstand von der Füllstation bis zu dem Obertrum des Förderbandes geringer ist als die Länge des unbefüllten Sackes. Das untere Ende des noch nicht gefüllten Sackes liegt daher abgeknickt auf dem Obertrum des Förderbandes. Bei der Befüllung des Sackes wird nun der Füllschlag dadurch gedämpft, daß er auf den Boden des Förderbandes schlägt und den eventuell noch nicht vollständig ausgehärteten Schweißbereich in der Bodennaht nicht schlagartig belastet. Nachdem diese dämpfende Vorfüllung erreicht ist, ergibt sich nun aber das Problem, eine gute Bodenausbildung des Sackes zu erreichen. Hierzu wird nun die an diesem Ende des Förderbandes angeordnete Umlenkrolle abgesenkt. Um das Füllgut zu verdichten, wird das Förderband über den unter dem Obertrum im Bereich der Füllstation angeordneten Rüttler in eine Rüttelbewegung versetzt, um dem Sackboden entsprechende Rüttlestöße zur Verdichtung des Füllmaterials zu erteilen.This object is achieved on the basis of a generic device by the additional features of the characterizing part of Claim 1 solved. Accordingly, the conveyor belt in the area below the filling station by pivoting the deflection roller can be lowered and raised again. Under the upper run of the conveyor belt, a vibrator is additionally arranged in the region of the filling station. By means of this embodiment of the conveyor belt, the following gentle filling process of the bag held in the filling station is possible. First, the Unfilled bag hung with the not yet cooled bottom seam in the filling station, the gripper of the filling station grab the bag at its open end. The closed end of the lies on the arranged below the filling station upper run of the conveyor belt, wherein the distance from the filling station to the upper run of the conveyor belt is less than the length of the unfilled bag. The lower end of the not yet filled bag is therefore bent on the upper run of the conveyor belt. When filling the bag, the filling shock is now damped by the fact that it strikes the bottom of the conveyor belt and the possibly not fully cured welding area in the bottom seam is not charged abruptly. After this damping pre-filling is achieved, but now there is the problem of achieving a good bottom formation of the bag. For this purpose, the deflecting roller arranged at this end of the conveyor belt is lowered. In order to compact the filling material, the conveyor belt is placed in a shaking motion via the vibrator arranged below the upper strand in the region of the filling station, in order to give the bag bottom corresponding crushing joints for compacting the filling material.

Das Wesen der Erfindung liegt darin, daß eine Kombination zwischen einem abschwenkbaren Förderbandteil und einem Rüttler beziehungsweise Vibrator unterhalb des Obertrums geschaffen wird. Grundsätzlich ist zwar das Vorsehen von derartigen Rüttlern oder Vibratoren bei Ausführungen bekannt, bei denen mit Abstand zueinander angeordnete Rollen anstelle eines Förderbandes vorgesehen werden. Bei diesen beabstandet voneinander angeordneten Rollen steht allerdings keine ununterbrochene Auflagefläche für den Sack zur Verfügung. Gerade beim Vorsehen von voneinander beabstandeten Rollen als Auflagefläche bestünde aber die Gefahr, daß ein nicht oder nur teilweise befüllter Sack mit seinem Bodenteil zwischen diese Rollen gerät und sich dort auf irgendeine Art und Weise verklemmt.The essence of the invention is that a combination between a swing-away conveyor belt part and a vibrator or vibrator is created below the upper run. In principle, although the provision of such vibrators or vibrators in embodiments is known in which spaced rollers are provided instead of a conveyor belt. In these spaced-apart rollers, however, there is no uninterrupted bearing surface for the bag available. Especially when providing spaced-apart rollers as a bearing surface but there is a risk that a not or only partially filled bag with its bottom part between these roles and get jammed there in some way.

Vorteilhafte Ausgestattungen der Erfindung ergeben sich aus den auf den Hauptanspruch zurückbezogenen Unteransprüchen.Advantageous Ausgestattungen of the invention will become apparent from the back to the main claim dependent claims.

Demnach kann die Umlenkrolle über ein pneumatisch oder hydraulisch antreibbares Hebelgestänge verschwenkbar sein.Accordingly, the deflection roller can be pivoted via a pneumatically or hydraulically driven lever linkage.

Während die Umlenkrolle des Förderbandes periodisch heb- und absenkbar ist, kann dem Sackboden während des Befüllens eine niederfrequente Rüttelbewegung aufgeprägt werden, wie dies zuvor schon beschrieben wurde.While the deflection roller of the conveyor belt is raised and lowered periodically, the bag bottom can be impressed during filling a low-frequency shaking movement, as previously described.

Auf dem Förderband können querverlaufende Stollen angeordnet sein. Der Abstand zwischen den Stollen ist so gewählt, daß zwischen diesen ein gefüllter Sack aufgenommen werden kann. Sind derartige querverlaufende Stollen vorhanden, ergibt sich das Problem, daß die über ein Transportgreiferpaar antransportieren leeren Sackabschnitte bei der Übergabe in die Füllstation, d.h. an die Greifer der Füllstation, mit ihrem unten frei hängenden Ende gegen die Stollen schlagen und daß dadurch das freie Ende sich nicht richtig auf das Förderband zwischen den Stollen ablegt. Daher kann nach einer bevorzugten Lösung der Erfindung entgegen der Transportrichtung der von den Greifern in die Füllstation antransportieren Säkke vor und oberhalb des Förderbandes eine quer zur Transportrichtung verlaufende Stange angeordnet sein, über die die Säcke derart ziehbar sind, daß sie sich durch eine gezielte Schwenkbewegung mit dem Sackboden zwischen zwei Stollen des Förderbandes ablegen.On the conveyor belt transverse lugs can be arranged. The distance between the studs is chosen so that a filled bag can be received between them. If such transverse studs are present, there is the problem that the empty bag sections to be transported by means of a pair of transporting grapples, when transferred to the filling station, i. at the gripper of the filling station, with its free hanging down end beat against the studs and that thereby the free end does not lie properly on the conveyor belt between the studs. Therefore, according to a preferred solution of the invention against the transport direction of transporting the grippers in the filling Säkke before and above the conveyor belt extending transversely to the transport direction rod can be arranged over which the sacks are pulled so that they by a targeted pivoting movement Put the bag bottom between two lugs of the conveyor belt.

Das gesamte Förderband kann höhenverstellbar im Maschinengestell gelagert sein. Hierdurch ist eine Anpassung an ein unterschiedliches Format der Säcke problemlos möglich.The entire conveyor belt can be height-adjustable stored in the machine frame. As a result, an adaptation to a different format of the bags is easily possible.

Wie bereits in der EP 290 879 A2 beschrieben, ist eine Vorrichtung zum Befüllen und Verschließen einseitig offener Säcke, wie sie hier im einzelnen beschrieben wird, Teil einer Anlage zum Herstellen von Säcken, Befüllen der Säcke mit Füllgut und zum Abtransport der befüllten Säcke.As already described in EP 290 879 A2, a device for filling and closing unilaterally open bags, as described in detail here, is part of a system for producing sacks, filling the bags with filling material and for transporting the filled sacks.

Die Fig. 1 zeigt die Gesamtansicht einer derartigen Anlage zum Herstellen von Säcken, Befüllen der Säcke mit einem Füllgut und zum Abtransport der gefüllten Säcke. Die gesamte Anlage ist mit 10 bezeichnet. Von einer Vorratsrolle 12 wird ein mit Seitenfalten versehener Schlauch aus thermoplastischem Kunststoff 14 abgezogen und einer ersten Schweißstation 16 zum Ausbilden der Bodennaht zugeführt. Die entsprechend mit der Bodennaht versehenen und mittels eines an sich bekannten Messers abgetrennten Sackabschnitte werden über Greiferpaare 18, 20 einer Füllstation 22 zugeführt. Dort wird der jeweilige Sackabschnitt 24 von stationären Füllgreifern erfaßt und gehalten.Fig. 1 shows the overall view of such a system for producing sacks, filling the bags with a product and for transporting the filled bags. The entire system is designated 10. From a supply roll 12 a gusseted hose made of thermoplastic material 14 is withdrawn and fed to a first welding station 16 for forming the bottom seam. The correspondingly provided with the bottom seam and separated by means of a known knife bag sections are fed via gripper pairs 18, 20 of a filling station 22. There, the respective bag portion 24 is detected and held by stationary Füllgreifern.

Mit seinem freien Ende 26 liegt der Sack 24 auf dem Obertrum 28 eines Förderbandes 30, das unterhalb der Füllstation 22 beginnt.With its free end 26 of the bag 24 is located on the upper strand 28 of a conveyor belt 30, which begins below the filling station 22.

Das Förderband 30 ist höhenverstellbar angeordnet. Der Tragbalken des Förderbandes 30 hat in seiner Mitte eine horizontale Konsole mit Führungsbacken, die zwischen in der Fig. 2 dargestellten Führungen 32 gleitend geführt sind. Um das Förderband 30 heben und senken zu können, ist ein Getriebemotor 34 mit einer antreibbaren Spindel 36 vorhanden, über die die stufenlose Höhenanpassung des Förderbandes erfolgen kann. Die Höhenanpassung des Förderbandes ist zur Anpassung an unterschiedliche Formate, d.h. Längen, der Säcke 24 notwendig.The conveyor belt 30 is arranged vertically adjustable. The support beam of the conveyor belt 30 has in its center a horizontal bracket with guide jaws which are slidably guided between guides 32 shown in FIG. In order to raise and lower the conveyor belt 30, a geared motor 34 is provided with a drivable spindle 36, via which the continuous height adjustment of the conveyor belt can take place. The height adjustment of the conveyor belt is to adapt to different formats, i. Lengths of sacks 24 necessary.

Das hier dargestellte Förderband 30 weist querverlaufende Stollen 38 auf, die den Transport der mit Schüttgut befüllten Säcke 24 erleichtern sollen.The conveyor belt 30 shown here has transverse lugs 38, which should facilitate the transport of bags filled with bulk material 24.

Wie insbesondere der Fig. 2 zu entnehmen ist, ist die Umlenkrolle 40 an dem freien Ende des Förderbandes 30, das unter der Füllstation liegt, abschwenkbar. Die Umlenkrolle 40 ist in nicht näher dargestellter Art und Weise seitlich über Seitenbleche gelagert. Diese Seitenbleche sind um ein Schwenklager 42 (vgl. Fig. 2) verschwenkbar. Die Verschwenkung erfolgt über eine Pneumatikkolbenzylinderanordnung 44, die über einen Schwenkhebelmechanismus 46, der um einen Drehpunkt 48 gelagert ist, die Umlenkrolle 40 verschwenken kann.As can be seen in particular from FIG. 2, the deflection roller 40 can be pivoted away at the free end of the conveyor belt 30 which lies below the filling station. The guide roller 40 is mounted in a manner not shown laterally over side plates. These side panels are pivotable about a pivot bearing 42 (see Fig. 2). The pivoting takes place via a pneumatic piston cylinder arrangement 44, which can pivot the deflection roller 40 via a pivot lever mechanism 46, which is mounted about a pivot point 48.

Die einzelnen Schritte des Befüllens des Sackes 24 werden anhand der Fig. 2-4 erläutert.The individual steps of filling the bag 24 will be explained with reference to FIGS. 2-4.

In Fig. 2 ist ein Sack 24 von dem Greiferpaar 50 in der Füllstation 22 erfaßt. Das untere Ende 26 mit der noch nicht voll ausgehärteten Schweißnaht (hier nicht dargestellt) liegt abgeknickt auf dem Obertrum 28 des Förderbands 30 auf. Das intermittierend bewegbare Förderband steht in dieser Phase still. In der Füllstation wird der Sack 24 nunmehr in an sich bekannter Weise befüllt. Das Füllgut wird aufgrund der Anordnung des Sackes 24, die zuvor beschrieben wurde, nicht unmittelbar die Bodenschweißnaht voll beanspruchen. Allerdings wird sich der Sackboden in dieser Anordnung nicht wunschgemäß ausbilden.In Fig. 2, a bag 24 is detected by the gripper pair 50 in the filling station 22. The lower end 26 with the not yet fully cured weld (not shown here) is bent on the upper run 28 of the conveyor belt 30 on. The intermittently movable conveyor belt is stationary in this phase. In the filling station, the bag 24 is now filled in a conventional manner. Due to the arrangement of the bag 24, which has been described above, the filling material does not immediately fully stress the bottom weld seam. However, the bag bottom will not form as desired in this arrangement.

Daher wird, wie in Fig. 3 dargestellt, über das Gestänge 46 die Umlenkrolle 40 und damit das gesamte Ende des Förderbandes 30 nach unten hin abgeschwenkt, so daß der sich füllende Sack 48 frei nach unten hängt. Während des Abschwenkens des Förderbandes 30 wird das Obertrum 28 durch eine Umlenkrolle 52 unterstützt. Anschließend wird noch während des Befüllvorganges, wie in Fig. 4 dargestellt, das Förderband wieder in die Ausgangsstellung zurückgeschwenkt. Das Hin- und Herschwenken des abschwenkbaren Endes des Förderbandes 30 kann periodisch wiederholt werden, um das Schüttgut im Sack 24 zu verdichten. Zur intensiveren Verdichtung des Schüttgutes ist zusätzlich ein von seiner Bauweise her als solches bekannter Rüttler 54 unterhalb des Obertrums 28 des Förderbandes 30 angeordnet, über den höherfrequente Rüttelbewegungen auf den Sackboden ausgeübt werden können, wie dies anhand der Fig. 4 verdeutlicht ist. Nach Befüllen des Sacks 24 wird dieser von einem anderen Transportgreiferpaar in bekannter Weise erfaßt und zu einer Schweißstation zum Verschließen der offenen Seite transportiert. Während dieser Verfahrbewegung wird das Förderband 30 zum Transport des Sackes fortbewegt.Therefore, as shown in Fig. 3, via the linkage 46, the guide roller 40 and thus the entire end of the conveyor belt 30 is pivoted downwards, so that the filling bag 48 is hanging freely down. During the pivoting of the conveyor belt 30, the upper strand 28 is supported by a deflection roller 52. Subsequently, during the filling process, as shown in Fig. 4, the conveyor belt is pivoted back to the starting position. The swinging back and forth of the swing-away end of the conveyor belt 30 can be repeated periodically to compress the bulk material in the bag 24. For more intensive compaction of the bulk material, a vibrator 54, known from its design as such, is additionally arranged below the upper run 28 of the conveyor belt 30, via which higher-frequency vibrating movements are exerted on the bottom of the bag can be, as illustrated with reference to FIG. 4. After filling the bag 24 this is detected by another pair of transport gripper in a known manner and transported to a welding station for closing the open side. During this movement, the conveyor belt 30 is moved to transport the bag.

In den Fig. 1 und 2 ist eine quer zur Transportrichtung des zur Füllstation antransportierten Sackes 24 angeordnete Stange 56 vorhanden. Über diese Stange wird der mit dem Greiferpaar 20 zurFüllstation bewegte Sack 24 gezogen. Das über die Stange 56 gezogene Ende des Sacks 24 schwingt während des Transports zur Füllstation zwischen zwei Stollen 38 des Transportbandes 30, so daß sich das Ende 26 des Sackes 24 ohne am Stollen 38 anzustoßen glatt im Zwischenraum zwischen den zwei Stollen 38, wie dies in den Fig. 1 und 2 dargestellt ist, ablegt.In FIGS. 1 and 2, a rod 56 arranged transversely to the transport direction of the bag 24 transported to the filling station is provided. About this rod of moving with the gripper pair 20 to the filling station bag 24 is pulled. The pulled over the rod 56 end of the bag 24 vibrates during transport to the filling station between two lugs 38 of the conveyor belt 30 so that the end 26 of the bag 24 without abutting the lug 38 smoothly in the space between the two lugs 38, as shown in Figs. 1 and 2 is shown, stores.

Das untere Trum des Förderbandes legt sich während des Abschwenkens des Förderbandes an den Unterstützungsrollen 53 an.The lower run of the conveyor belt abuts against the support rollers 53 during the pivoting of the conveyor belt.
