Description

Die vorliegende Erfindung betrifft eine Klemmvorrichtung für das Klemmen eines Sackabschnitts einer Folienbahn in einer Füllstation einer Sackfüllanlage sowie ein Verfahren für das Klemmen und Füllen eines Sackabschnitts einer Folienbahn in einer Füllstation einer Sackfüllanlage.The present invention relates to a clamping device for clamping a bag section of a film web in a filling station of a bag filling system and to a method for clamping and filling a bag section of a film web in a filling station of a bag filling system.

Sackfüllanlagen sind grundsätzlich bekannt, siehe WO2004/108536 , und werden dafür verwendet, um Sackabschnitte von einer Folienbahn abzulängen und mit einem Schüttgut zu befüllen. Hierfür weist eine bekannte Sackfüllanlage üblicherweise eine Füllstation mit einem Fülltrichter auf, über welchen das Schüttgut in das Innere des Sackabschnitts gelangt. Um sicherzustellen, dass der Sackabschnitt für den Füllvorgang eine definierte Befüllposition aufweist, ist bekannterweise eine Klemmvorrichtung mit zwei Klemmbacken vorhanden. Diese dient dazu, zwischen den beiden Klemmbacken den Sackabschnitt zu halten und dementsprechend relativ exakt zu dem Fülltrichter zu positionieren. Damit wird sichergestellt, dass das eingefüllte Schüttgut den Sackabschnitt nicht in unerwünschter Weise vom Fülltrichter abzieht und entfernt. Für den Weitertransport nach dem Befüllen mittels des Fülltrichters ist üblicherweise eine Greifvorrichtung bekannt, welche seitlich ein Greifen des Sackabschnitts durchführt. Das seitliche Greifen führt dazu, dass unterhalb der haltenden Klemmbacken ebenfalls ein klemmendes Greifen durch die Greifvorrichtung stattfindet.Bag filling systems are generally known, see WO2004 / 108536 , and are used to cut off sack sections of a film web and to fill with a bulk material. For this purpose, a known bag filling usually a filling station with a hopper over which the bulk material passes into the interior of the bag section. To ensure that the bag section for the filling process has a defined filling position, is known to be a Clamping device with two jaws available. This serves to hold the sack portion between the two jaws and accordingly to position relatively accurately to the hopper. This ensures that the filled bulk material does not undesirably pull the bag section off the hopper and remove it. For further transport after filling by means of the hopper usually a gripping device is known, which performs laterally gripping the bag section. The lateral gripping means that below the holding jaws also takes place a clamping gripping by the gripping device.

Nachteilhaft bei bekannten Klemmvorrichtungen ist es, dass das Greifen nur mit relativ großem Aufwand sauber und insbesondere faltenfrei erfolgt. So wird durch das Einfüllen des Schüttguts die jeweilige Folienlage des Sackabschnitts verworfen und zwar in nicht vorhersagbarer Weise. So kann es dazu kommen, dass ein Faltenwurf insbesondere in dem Bereich entsteht, in welchem anschließend ein klemmendes Greifen mithilfe der Greifvorrichtung erfolgen soll. So besteht also die Gefahr, dass die Greifvorrichtung einen Faltenwurf greift und damit eine mechanische Einwirkung auf diesen Faltenwurf erzeugt. Dies kann zu unerwünschter mechanischer Belastung und insbesondere zu einer Fehlstelle im Sackabschnitt, z. B. zu einer Sollbruchstelle, führen. Auch sind solche Faltenabschnitte dazu geneigt, dass die Klemmung nicht in ausreichender Weise an der Greifvorrichtung stattfindet. So wird der Weitertransport nicht in der notwendigen sicheren Weise sichergestellt.A disadvantage of known clamping devices is that the gripping takes place only with relatively great effort clean and especially wrinkle-free. Thus, by filling the bulk material, the respective film layer of the bag section is discarded and indeed in an unpredictable manner. So it can happen that a drape especially in the area arises in which then a clamping gripping should be done using the gripping device. So there is the danger that the gripping device engages a drape and thus produces a mechanical action on this drape. This can lead to unwanted mechanical stress and in particular to a defect in the bag section, z. B. lead to a predetermined breaking point. Also, such wrinkle sections are inclined so that the clamping does not take place sufficiently on the gripping device. Thus, the onward transport is not ensured in the necessary safe manner.

Es ist Aufgabe der vorliegenden Erfindung, die voranstehend beschriebenen Nachteile zumindest teilweise zu beheben. Insbesondere ist es Aufgabe der vorliegenden Erfindung, in kostengünstiger und einfacher Weise eine Reduktion des Faltenrisikos für die Greifvorrichtung zur Verfügung zu stellen. Dies soll insbesondere bei gleichbleibender oder sogar reduzierter Taktzeit dieser Füllstation der Sackfüllanlage erfolgen.It is an object of the present invention to at least partially overcome the disadvantages described above. In particular, it is an object of the present invention to provide a cost-effective and simple way to reduce the risk of wrinkles for the gripping device available. This should be done especially at constant or even reduced cycle time of this filling the bag filling.

Voranstehende Aufgabe wird gelöst durch eine Klemmvorrichtung mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 9. Weitere Merkmale und Details der Erfindung ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen. Dabei gelten Merkmale und Details, die im Zusammenhang mit der erfindungsgemäßen Klemmvorrichtung beschrieben sind, selbstverständlich auch im Zusammenhang mit dem erfindungsgemäßen Verfahren und jeweils umgekehrt, sodass bezüglich der Offenbarung zu den einzelnen Erfindungsaspekten stets wechselseitig Bezug genommen wird bzw. werden kann.The above object is achieved by a clamping device having the features of claim 1 and a method having the features of claim 9. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. Here are features and details that are described in connection with the clamping device according to the invention, of course, also in Connection with the method according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or may be made.

Eine erfindungsgemäße Klemmvorrichtung dient dem Klemmen eines Sackabschnitts einer Folienbahn in einer Füllstation einer Sackfüllanlage. Hierfür weist die erfindungsgemäße Klemmvorrichtung eine erste Klemmbacke und eine relativ zur ersten Klemmbacke bewegbare zweite Klemmbacke für das Klemmen des Sackabschnitts in einem Klemmabschnitt in dessen Kopfbereich auf. Eine erfindungsgemäße Klemmvorrichtung zeichnet sich dadurch aus, dass an der ersten Klemmbacke eine erste Zusatzbacke bewegbar gelagert ist. Dabei ist an der zweiten Klemmbacke eine zweite Zusatzbacke angeordnet, für ein Klemmen des Sackabschnitts an einem Zusatzklemmabschnitt unterhalb des Klemmabschnitts.A clamping device according to the invention serves for clamping a bag section of a film web in a filling station of a bag filling installation. For this purpose, the clamping device according to the invention has a first clamping jaw and a second jaw movable relative to the first clamping jaw for clamping the bag section in a clamping section in its head region. A clamping device according to the invention is characterized in that a first additional jaw is movably mounted on the first jaw. In this case, a second additional jaw is arranged on the second jaw for clamping the bag section at an additional clamping portion below the clamping portion.

In erfindungsgemäßer Weise greift diese Klemmvorrichtung also auf bekannte Klemmvorrichtungen zurück. Die Funktionalität der ersten Klemmbacke und der zweiten Klemmbacke führt dazu, dass diese gegeneinander relativ bewegbar sind. Insbesondere handelt es sich bei der ersten Klemmbacke um eine stationär an der Sackfüllanlage oder der Füllstation angeordnete Klemmbacke. Die zweite Klemmbacke ist bewegbar zur ersten Klemmbacke und damit auch zur Sackfüllanlage und zur Füllstation gelagert. Durch ein Zusammenfahren der beiden Klemmbacken reduziert sich der Klemmspalt zwischen den beiden Klemmbacken. Erreicht diese Breite des Klemmspalts einen Wert unterhalb der Dicke des Sackabschnitts, so erfolgt das Klemmen bzw. die klemmende Befestigung im Klemmabschnitt.In accordance with the invention, this clamping device thus accesses known clamping devices. The functionality of the first jaw and the second jaw results in being relatively movable relative to each other. In particular, the first clamping jaw is a clamping jaw arranged stationarily on the bag filling system or the filling station. The second jaw is movably mounted to the first jaw and thus also to the bag filling and filling station. By a collapse of the two jaws reduces the nip between the two jaws. If this width of the clamping gap reaches a value below the thickness of the bag section, the clamping or the clamping attachment takes place in the clamping section.

Unter dem Kopfbereich des Sackabschnitts ist dabei der Bereich unterhalb der Oberkante, also des Kopfes des Sackabschnitts, zu verstehen. Der Sackabschnitt ist dabei aufrecht stehend in der Sackfüllanlage angeordnet. Das Schüttgut wird von oben nach unten, also in den offenen Bereich im Kopfbereich, eingefüllt. Der gegenüberliegende Abschnitt, also das gegenüberliegende Ende des Sackabschnitts ist als Bodenbereich bzw. als Bodenende gekennzeichnet.Under the head portion of the bag section is the area below the upper edge, so the head of the bag section to understand. The bag section is arranged upright in the bag filling system. The bulk material is filled from top to bottom, ie in the open area in the head area. The opposite section, that is, the opposite end of the bag section is characterized as a bottom region or as a bottom end.

Im Gegensatz zu bekannten Klemmvorrichtungen ist bei einer erfindungsgemäßen Klemmvorrichtung nun eine zusätzliche Zusatzklemmvorrichtung vorgesehen. Diese weist eine erste Zusatzbacke und eine zweite Zusatzbacke auf. Diese beiden Zusatzbacken sind mit der jeweiligen Klemmbacke korreliert und an diesen angeordnet. Entscheidend dabei ist, dass zumindest die erste Zusatzbacke auch bewegbar an der ersten Klemmbacke gelagert ist. Dabei sind die erste Klemmbacke und die erste Zusatzbacke, insbesondere mit Bezug auf die Transportrichtung des Sackabschnitts, von der Füllstation weg und damit dem Sackabschnitt nachgeordnet angeordnet.In contrast to known clamping devices, an additional auxiliary clamping device is now provided in a clamping device according to the invention. This has a first additional jaw and a second additional jaw. These two additional jaws are correlated with the respective jaw and arranged on these. It is crucial that at least the first additional jaw is also movably mounted on the first jaw. In this case, the first clamping jaw and the first additional jaw, in particular with respect to the transport direction of the bag section, away from the filling station and thus arranged downstream of the bag section.

Durch das Vorsehen einer Zusatzklemmvorrichtung mit zwei Zusatzbacken wird ein Zusatzklemmabschnitt unterhalb des Klemmabschnitts möglich. Mit anderen Worten wird der Sackabschnitt an zwei unterschiedlichen Abschnitten, nämlich dem Zusatzklemmabschnitt und dem Klemmabschnitt gehalten, insbesondere geklemmt. Dies führt dazu, dass zwischen diesen beiden Abschnitten, also zwischen dem Klemmabschnitt und dem Zusatzklemmabschnitt, eine definierte Positionierung des Sackabschnitts erfolgt. Der Sackabschnitt wird also in dem Bereich zwischen dem Zusatzklemmabschnitt und dem Klemmabschnitt straff gezogen, sodass etwaige Falten, welche während dem Füllvorgang entstehen würden, überhaupt nicht auftreten. Dabei sind die Zusatzbacken derart ausgebildet, dass sie vorzugsweise bereits zu Beginn oder sogar vor Beginn des Füllvorgangs eine klemmende Befestigung im Zusatzklemmabschnitt erzielen können.By providing an additional clamping device with two additional jaws an additional clamping portion below the clamping portion is possible. In other words, the bag section is held at two different sections, namely the additional clamping section and the clamping section, in particular clamped. As a result, a defined positioning of the bag section takes place between these two sections, that is to say between the clamping section and the additional clamping section. The bag section is thus drawn taut in the area between the additional clamping section and the clamping section, so that any wrinkles that would arise during the filling process, do not occur at all. The additional jaws are designed such that they can preferably already at the beginning or even before the start of the filling process can achieve a clamping attachment in the additional clamping section.

In erfindungsgemäßer Weise wird also bereits das Entstehen des Faltenwurfs vermieden. Ist bereits Faltenwurf entstanden, kann über eine Verwendung der beiden Zusatzbacken, insbesondere ein Glattziehen oder ein Entfernen des Faltenwurfs erfolgen, bevor die nachfolgende Greifvorrichtung für den Abtransport des Sackabschnitts zwischen dem Zusatzklemmabschnitt und dem Klemmabschnitt angreift. Es wird also eine definierte Position und eine definierte faltenfreie Situation für den Sackabschnitt zwischen dem Zusatzklemmabschnitt und dem Klemmabschnitt zur Verfügung gestellt.In accordance with the invention thus already the emergence of the drape is avoided. If wrinkling has already occurred, the use of the two additional jaws, in particular smooth drawing or removal of the drapery, can take place before the subsequent gripping device for removing the bag section between the additional clamping section and the clamping section engages. Thus, a defined position and a defined wrinkle-free situation for the bag section between the additional clamping section and the clamping section is provided.

Bei einer Sackfüllanlage, in welcher eine erfindungsgemäße Klemmvorrichtung zum Einsatz kommt, handelt es sich insbesondere um eine Anlage gemäß dem sogenannten Form, Fill and Seal (FFS)-Verfahren. Hierfür wird ausgehend von einer Vorlagerolle eine Folienbahn als Folienschlauch abgewickelt. Dieses Abwickeln erfolgt vorzugsweise kontinuierlich, sodass dieses anschließend über eine Puffervorrichtung, insbesondere ausgebildet als Tänzervorrichtung, in ein schubweises bzw. taktweises Vorschieben der Folienbahn umgewandelt werden kann. Als Nächstes folgen verschiedene weitere Stationen der Sackfüllanlage. So kann z. B. eine Eckschweißnaht mittels einer Siegelvorrichtung erzeugt werden. Über eine Bodenschweißnahtvorrichtung wird die Bodensiegelnaht erzeugt und es erfolgt gleichzeitig ein Ablängen der Folienbahn in einzelne Sackabschnitte. Ab dieser Station erfolgt ein seitliches Weitertransportieren der jeweiligen Sackabschnitte zur Füllstation, bei welcher die erfindungsgemäße Klemmvorrichtung zum Einsatz kommt. Nachgeordnet in Transportrichtung sind noch eine Kopfnahtsiegelstation sowie eine Kopfnahtkühlstation zur Finalisierung des Sackabschnitts in gefüllter Form angeordnet. Wie bereits zu erkennen ist, ist für den Weitertransport ab der Bodennahtsiegelstation, ab welcher auch ein Ablängen in einzelne Sackabschnitte erfolgt, üblicherweise ein seitlicher Transport mittels einer Vielzahl von Greifvorrichtungen vorgesehen. Diese Greifvorrichtungen sind vorzugsweise im Pendelbetrieb angeordnet und erzeugen den gewünschten Weitertransport von Station zu Station.In a bag filling plant, in which a clamping device according to the invention is used, it is in particular a system according to the so-called form, fill and seal (FFS) method. For this purpose, starting from a Vorlagerolle a film web is handled as a film tube. This unwinding preferably takes place continuously, so that it can then be converted via a buffer device, in particular designed as a dancer device, into a batch-wise or cyclically advancing the film web. Next are various other stations of the bag filling plant. So z. B. a corner weld can be generated by means of a sealing device. The bottom seam is produced by means of a bottom weld seam device and at the same time the film web is cut into individual bag sections. From this station there is a lateral further transport of the respective bag sections to the filling station, in which the clamping device according to the invention is used. Subordinated in the transport direction are still a top seal station and a Kopfnahtkühlstation for finalizing the bag section arranged in a filled form. As can already be seen, a lateral transport by means of a plurality of gripping devices is usually provided for the further transport from the bottom seam sealing station, from which also a cutting into individual bag sections takes place. These gripping devices are preferably arranged in pendulum mode and generate the desired onward transport from station to station.

Neben der Faltenfrage und der damit einhergehenden höheren Sicherheit für den Weitertransport mit der Greifvorrichtung ist insbesondere auch eine geringe oder überhaupt keine Beeinflussung der Taktzeit der jeweiligen Füllstation der Sackfüllanlage zu erkennen. So wird durch die bewegbare Anordnung der ersten Zusatzbacke an der ersten Klemmbacke eine Relativbewegung zwischen der ersten Zusatzbacke und der ersten Klemmbacke möglich. Dabei ist es unerheblich, ob die erste Klemmbacke stationär oder ebenfalls bewegbar an der Füllstation der Sackfüllanlage angeordnet ist. Entscheidend ist die Relativbewegung zwischen erster Zusatzbacke und erster Klemmbacke, die durch die erfindungsgemäße bewegbare Lagerung möglich ist. Da die erste Klemmbacke und damit auch die erste Zusatzbacke vorzugsweise in Transportrichtung des Sackabschnitts dem Sackabschnitt nachgeordnet angeordnet ist, kann die erste Zusatzbacke nach erfolgtem und erfolgreichen Greifen mittels der Greifvorrichtung bereits wegbewegt werden und damit den Weg für die nachfolgende Transportbewegung der Greifvorrichtung frei machen. Diese voranstehende Bewegung der ersten Zusatzbacke kann bereits erfolgen, wenn die erste Klemmbacke sich noch in klemmenden Eingriff mit der zweiten Klemmbacke befindet. So kann bereits vor dem Beenden des Füllvorgangs in der Füllstation die Zusatzklemmvorrichtung und damit die erste Zusatzbacke wegschwenken, um den nachfolgenden Schritt der Transportbewegung der Greifvorrichtung von möglichen Hindernissen frei zu machen. Während bei einem einfachen Anordnen einer festen Zusatzbacke an der Klemmbacke abgewartet werden müsste, bis Klemmbacke und damit auch die Zusatzbacke komplett von der Klemmposition entfernt werden, um die nachfolgende Transportbewegung mit der Greifvorrichtung durchzuführen. Erfindungsgemäß wird also nicht nur der potentielle Faltenwurf und das damit einhergehende Problem behoben, sondern vielmehr auch die Taktzeit der Füllstation reduziert.In addition to the wrinkle issue and the associated higher security for onward transport with the gripping device, in particular, little or no influence on the cycle time of the respective filling station of the bag filling system can be recognized. Thus, a relative movement between the first additional jaw and the first jaw is possible by the movable arrangement of the first additional jaw on the first jaw. It is irrelevant whether the first jaw is arranged stationary or movable at the filling station of the bag filling system. Decisive is the relative movement between the first additional jaw and the first jaw, which is possible by the movable mounting according to the invention. Since the first jaw and thus also the first additional jaw is preferably disposed downstream of the bag section in the transport direction of the bag section, the first additional jaw can already be moved away after successful and successful gripping by means of the gripping device and thus clear the way for the subsequent transport movement of the gripping device. This above movement of the first additional jaw can already take place when the first jaw is still in clamping engagement with the second jaw. Thus, even before the end of the filling process in the filling station, the additional clamping device and thus the first additional jaw swing away to the subsequent step of the transport movement of the gripping device of possible obstacles free. While in a simple arrangement of a fixed additional jaw on the jaw would have to wait until the jaw and thus the additional jaw are completely removed from the clamping position to perform the subsequent transport movement with the gripping device. According to the invention not only the potential drape and the associated problem is solved, but also reduces the cycle time of the filling station.

Die einzelnen Backen, also die Klemmbacken und die Zusatzbacken, können dabei Verlängerungsmöglichkeiten oder Verlängerungselemente aufweisen, welche eine Anpassung an unterschiedliche Sackbreiten aufweisen.The individual jaws, that is, the jaws and the additional jaws, can thereby have extension options or extension elements which have an adaptation to different sack widths.

Vorteilhaft ist es, wenn bei einer erfindungsgemäßen Klemmvorrichtung die erste Klemmbacke stationär zu einem Rahmen der Klemmvorrichtung angeordnet ist. Diese stationäre Ausführungsform bringt eine Reduktion der Komplexität und der Konstruktionsweise mit sich. Dies führt dazu, dass nur die zweite Klemmbacke für die gewünschte Klemmwirkung bewegt werden muss. Auch wird ein reduzierter Platzbedarf für die gesamte Klemmvorrichtung erzielbar. Beispielsweise weist die Füllstation einen Rahmen auf, welcher ein Teil der Klemmvorrichtung oder ein Teil der Füllstation ist. Dies kann auch ein Teil des Rahmengehäuses der gesamten Sackfüllanlage sein. Mit anderen Worten erfolgt die Relativbewegung ausschließlich durch eine Bewegung der zweiten Klemmbacke, um die Klemmfunktionalität zur Verfügung zu stellen. Auch die bewegbare Lagerung der ersten Zusatzbacke an der ersten Klemmbacke wird auf diese Weise weiter vereinfacht, da keine doppelte Relativbewegung zwischen erster Klemmbacke und Rahmen und zwischen erster Zusatzbacke und erster Klemmbacke erfolgen muss. Auch in dieser Hinsicht wird also die Komplexität einer erfindungsgemäßen Klemmvorrichtung durch diese Ausführungsform reduziert.It is advantageous if, in a clamping device according to the invention, the first jaw is arranged stationary to a frame of the clamping device. This stationary embodiment involves a reduction in complexity and construction. This means that only the second jaw must be moved for the desired clamping action. Also, a reduced space requirement for the entire clamping device can be achieved. For example, the filling station has a frame, which is a part of the clamping device or a part of the filling station. This can also be part of the frame housing of the entire bag filling system. In other words, the relative movement takes place exclusively by a movement of the second jaw in order to provide the clamping functionality. The movable mounting of the first additional jaw on the first jaw is further simplified in this way, since no double relative movement between the first jaw and frame and between the first additional jaw and the first jaw must be made. Also in this regard, therefore, the complexity of a clamping device according to the invention is reduced by this embodiment.

Vorteilhaft ist es ebenfalls, wenn bei einer erfindungsgemäßen Klemmvorrichtung zwischen dem Zusatzklemmabschnitt und dem Klemmabschnitt ein Greifabschnitt angeordnet ist für das Greifen des Sackabschnitts zwischen den Klemmbacken und den Zusatzbacken mit einer Greifvorrichtung. Mit anderen Worten sind Zusatzklemmabschnitt und Klemmabschnitt voneinander in definierter Weise beabstandet. Dieser Abstand ist größer oder gleich der entsprechenden Greifbacken einer Greifvorrichtung. Diese Greifbacken können also zwischen Zusatzklemmabschnitt und Klemmabschnitt den Greifabschnitt des Sackabschnitts greifen und klemmend eine Befestigung in temporärer Weise für den Sackabschnitt zur Verfügung stellen. Mit anderen Worten lassen Zusatzklemmabschnitt und Klemmabschnitt durch entsprechende Ausbildung der Zusatzbacken und der Klemmbacken ausreichend Freiraum, um mit den Greifbacken einer Greifvorrichtung in dem Greifabschnitt ein Transportgreifen des Sackabschnitts zu ermöglichen.It is also advantageous if in a clamping device according to the invention between the additional clamping portion and the clamping portion a gripping portion is arranged for gripping the bag portion between the jaws and the additional jaws with a gripping device. In other words, additional clamping portion and clamping portion are spaced from each other in a defined manner. This distance is greater than or equal to corresponding gripping jaws of a gripping device. This gripping jaws can thus grab the gripping portion of the bag section between the additional clamping section and clamping section and provide an attachment in a temporary manner for the bag section in a clamping manner. In other words leave additional clamping section and clamping section by appropriate design of the additional jaws and the jaws sufficient space to allow the gripping jaws of a gripping device in the gripping portion a transport gripping the bag section.

Ebenfalls von Vorteil kann es sein, wenn bei einer erfindungsgemäßen Klemmvorrichtung die zweite Zusatzbacke stationär an der zweiten Klemmbacke angeordnet ist. Auch auf diese Weise kann eine Reduktion der Komplexität einer erfindungsgemäßen Klemmvorrichtung erzielt werden. So wird es möglich, die zweite Zusatzbacke gemeinsam mit der zweiten Klemmbacke zu bewegen. Insbesondere wird eine solche Ausführungsform ausgebildet mit einer stationär angeordneten ersten Klemmbacke, wie sie bereits erläutert worden ist. Eine separate Antriebsvorrichtung für die zweite Zusatzbacke wird auf diese Weise nicht mehr notwendig. Insbesondere sind die zweite Zusatzbacke und die zweite Klemmbacke in Transportrichtung des Sackabschnitts vor dem Sackabschnitt angeordnet.It may also be advantageous if, in a clamping device according to the invention, the second additional jaw is arranged stationarily on the second clamping jaw. In this way, a reduction in the complexity of a clamping device according to the invention can be achieved. So it is possible to move the second additional jaw together with the second jaw. In particular, such an embodiment is formed with a stationary arranged first jaw, as has already been explained. A separate drive device for the second additional jaw is no longer necessary in this way. In particular, the second additional jaw and the second jaw are arranged in the transport direction of the bag section in front of the bag section.

Vorteilhaft ist es weiter, wenn bei einer erfindungsgemäßen Klemmvorrichtung die erste Zusatzbacke und die erste Klemmbacke der zweiten Zusatzbacke und der zweiten Klemmbacke in Transportrichtung des Sackabschnitts in der Sackfüllanlage nachgeordnet sind. Das bedeutet, dass in Laufrichtung des Sackabschnitts, also zuerst die zweite Zusatzbacke und die zweite Klemmbacke und erst anschließend die erste Zusatzbacke und die erste Klemmbacke kommen. Zwischen den jeweiligen Backen ist dann der Sackabschnitt in klemmender Weise angeordnet. Die Transportrichtung ist dabei insbesondere auf eine Greif- und Pendelbewegung einer gesamten Greifvorrichtung der Sackfüllanlage ausgerichtet. So wird beispielsweise nach dem Ablängen eines Sackabschnitts eine Förderbewegung in pendelnder Weise von rechts nach links durchgeführt. Damit kann eine definierte Transportrichtung für den Sackabschnitt in der Sackfüllanlage zur Verfügung gestellt werden. Während des ersten Öffnens und noch während des Befüllens werden auf diese Weise diverse Vorteile erzielt. Insbesondere können die beschriebenen Taktvorteile hinsichtlich der Reduktion bzw. Beibehaltung der Taktzeit für den Füllvorgang durch diese Anordnung der Backen beibehalten werden bzw. erreicht werden.It is also advantageous if in a clamping device according to the invention, the first additional jaw and the first jaw of the second additional jaw and the second jaw are arranged downstream in the transport direction of the bag section in the bag filling. This means that in the direction of the bag section, so first the second additional jaw and the second jaw and only then the first additional jaw and the first jaw come. Between the respective jaws then the bag section is arranged in a clamping manner. The transport direction is oriented in particular to a gripping and oscillating movement of an entire gripping device of the bag filling system. Thus, for example, after the cutting to length of a bag section, a conveying movement is carried out in a pendulum fashion from right to left. Thus, a defined transport direction for the bag section in the bag filling system can be made available. During the first opening and while filling various advantages are achieved in this way. In particular, the described cycle advantages with regard to the reduction or maintenance of the cycle time for the filling process can be maintained or achieved by this arrangement of the jaws.

Vorteilhaft ist es ebenfalls, wenn bei einer erfindungsgemäßen Klemmvorrichtung ein Klemmantrieb für die Bewegung der zweiten Klemmbacke und ein Zusatzantrieb für die Bewegung der ersten Zusatzbacke vorgesehen sind, welche insbesondere unabhängig voneinander steuerbar und/oder regelbar sind. Die Antriebe können hydraulisch, pneumatisch oder auch motorisch ausgebildet sein. Damit wird eine unabhängige Bewegung der ersten Zusatzbacke von der zweiten Klemmbacke möglich. Dies führt zu einer erhöhten und verbesserten Flexibilität und damit zu einer weiteren möglichen Reduktion der Taktzeit. Insbesondere kann bei der Ausführungsform gemäß dem voranstehenden Absatz die erste Zusatzbacke bereits geöffnet werden, während sich die Klemmvorrichtung und damit die zweite Klemmbacke noch in klemmender Position befindet. Damit wird die bereits beschriebene Reduktion der Taktzeit für den Füllvorgang erzielt. Darüber hinaus ist nicht nur die Bewegung, sondern auch die Kraftstärke des Klemmens separat voneinander regelbar. Unnötiger Krafteinfluss auf das Material wird auf diese Weise besonders einfach und kostengünstig vermieden. Selbstverständlich kann für die Regelung und/oder Steuerung auch eine gemeinsame Kontrolleinheit für die beiden separaten Antriebe vorgesehen sein.It is also advantageous if in a clamping device according to the invention a clamping drive for the movement of the second jaw and an additional drive for the movement of the first additional jaw are provided, which in particular independently controllable and / or controllable. The drives can be designed hydraulically, pneumatically or motor. Thus, an independent movement of the first additional jaw of the second jaw is possible. This leads to increased and improved flexibility and thus to a further possible reduction of the cycle time. In particular, in the embodiment according to the preceding paragraph, the first additional jaw already be opened, while the clamping device and thus the second jaw is still in clamping position. This achieves the already described reduction of the cycle time for the filling process. In addition, not only the movement, but also the strength of the clamping can be controlled separately from each other. Unnecessary force on the material is thus avoided in a particularly simple and cost-effective manner. Of course, may be provided for the control and / or control and a common control unit for the two separate drives.

Ebenfalls von Vorteil ist es weiter, wenn bei einer erfindungsgemäßen Klemmvorrichtung die erste Zusatzbacke und/oder die zweite Zusatzbacke über einen Verbindungsabschnitt an der entsprechenden Klemmbacke gelagert sind, wobei der Lagerabschnitt einen zumindest abschnittsweise bogenförmigen Verlauf aufweist, um einen Greifabschnitt für ein Greifen mit einer Greifvorrichtung von der Seite des Sackabschnitts zugänglich zu machen. Dies führt zu einer besonders kostengünstigen und materialsparenden Lagerung der jeweiligen Zusatzbacke an der jeweiligen Klemmbacke. Gleichzeitig wird sichergestellt, dass durch einen bogenförmigen Verlauf von der Seite des Sackabschnitts her kein störendes Bauteil das Greifen mithilfe der Greifvorrichtung verhindert. Der bogenförmige Verlauf ist dabei z. B. im Wesentlichen C-förmig bzw. spiegelverkehrt C-förmig ausgebildet. So wird eine kraftschlüssige Lagerung der jeweiligen Zusatzbacke an der Klemmbacke möglich, ohne die Greifsituation negativ zu beeinflussen. Der jeweilige bogenförmige Verlauf des Lagerabschnitts ist dabei in Richtung der Sackmitte, ausgehend von den beiden seitlichen Enden des Sackabschnitts, versetzt. Vorzugsweise ist der Lagerabschnitt derart ausgebildet, dass für die jeweilige Klemmbacke und die jeweilige Zusatzbacke eine gleiche oder im Wesentlichen gleich lange Klemmlänge bzw. Klemmfläche für gleiche Klemmwirkungen zur Verfügung gestellt werden kann. Der bogenförmige Abschnitt des Lagerabschnitts kann dabei vom Material des Sackabschnitts angehoben oder ebenfalls anliegend zu diesem ausgebildet sein.It is also advantageous if, in a clamping device according to the invention, the first additional jaw and / or the second additional jaw are mounted on a connecting portion on the corresponding jaw, wherein the bearing portion has an at least partially arcuate course to a gripping portion for gripping with a gripping device accessible from the side of the bag section. This leads to a particularly cost-effective and material-saving storage of the respective additional jaw on the respective jaw. At the same time, it is ensured that an interfering component does not prevent gripping by means of the gripping device due to an arcuate course from the side of the bag section. The arcuate course is z. B. substantially C-shaped or mirror inverted C-shaped. Thus, a frictional storage of the respective additional jaw on the jaw is possible without affecting the gripping situation negative. The respective arcuate course of the bearing section is offset in the direction of the bag center, starting from the two lateral ends of the bag section. Preferably, the bearing portion is formed such that for the respective jaw and the respective additional jaw an equal or substantially equal length clamping length or clamping surface for the same clamping effects Can be made available. The arcuate portion of the bearing portion may be raised by the material of the bag portion or may also be formed adjacent to this.

Vorteilhaft ist es weiter, wenn bei einer erfindungsgemäßen Klemmvorrichtung der Klemmabschnitt und der Zusatzklemmabschnitt durch Ausbildung und Anordnung der Klemmbacken und der Zusatzbacken in dem Kopfbereich des Sackabschnitts angeordnet sind, welche sich vom Kopfende des Sackabschnitts weniger als ca. 10 % in Richtung des Bodenendes des Sackabschnitts erstrecken. Das bedeutet, dass im obersten Bereich des Sackabschnitts sowohl die Klemmung als auch die Zusatzklemmung stattfindet. Je weiter oben die erfindungsgemäße Klemmvorrichtung und erfindungsgemäße Funktionalität zur Verfügung stellt, umso weniger Beeinflussung findet für den Füllvorgang für den restlichen Sackabschnitt statt. Insbesondere wird während des Füllvorgangs ein Aufblähen und Auseinanderfalten des Sackabschnitts nur in geringem Maße negativ beeinflusst.It is also advantageous if, in a clamping device according to the invention, the clamping section and the additional clamping section are arranged by forming and arranging the clamping jaws and the additional jaws in the head region of the bag section, which extends from the top end of the bag section less than approximately 10% in the direction of the bottom end of the bag section extend. This means that both the clamping and the additional clamping takes place in the uppermost region of the bag section. The further above the clamping device according to the invention and functionality according to the invention makes available, the less interference takes place for the filling process for the remaining bag section. In particular, during the filling process, inflation and unfolding of the bag section is negatively influenced only to a slight extent.

Ebenfalls Gegenstand der vorliegenden Erfindung ist ein Verfahren für das Klemmen und Füllen eines Sackabschnitts einer Folienbahn in einer Füllstation einer Sackfüllanlage mittels einer Klemmvorrichtung, insbesondere gemäß der vorliegenden Erfindung, aufweisend die folgenden Schritte:

  • Schließen einer ersten Klemmbacke und einer zweiten Klemmbacke für ein Klemmen des Sackabschnitts in einem Klemmabschnitt in dessen Kopfbereich,
  • Schließen einer ersten Zusatzbacke und einer zweiten Zusatzbacke für ein Klemmen des Sackabschnitts in einem Zusatzklemmabschnitt unterhalb des Klemmabschnitts,
  • Start des Füllvorgangs des Füllens des Sackabschnitts,
  • Greifen des Sackabschnitts mit einer Greifvorrichtung in einem Greifabschnitt zwischen dem Zusatzklemmabschnitt und dem Klemmabschnitt,
  • Öffnen der beiden Zusatzbacken.
Likewise provided by the present invention is a method for clamping and filling a bag section of a film web in a filling station of a bag filling installation by means of a clamping device, in particular according to the present invention, comprising the following steps:
  • Closing a first clamping jaw and a second clamping jaw for clamping the bag section in a clamping section in its head region,
  • Closing a first additional jaw and a second additional jaw for clamping the bag section in an additional clamping section below the clamping section,
  • Start of the filling process of filling the bag section,
  • Gripping the bag section with a gripping device in a gripping section between the additional clamping section and the clamping section,
  • Opening the two additional jaws.

Insbesondere durch die Ausbildung der Klemmvorrichtung in erfindungsgemäßer Weise bringt ein erfindungsgemäßes Verfahren die gleichen Vorteile mit sich, wie sie ausführlich erläutert worden sind. So kann während des Füllvorgangs durch das Schließen der Zusatzbacken vor dem Füllvorgang bereits ein Öffnen der Zusatzbacken erfolgen. Der Transportweg für ein nachfolgendes Abtransportieren des gefüllten Sackabschnitts mithilfe der Greifvorrichtung ist auf diese Weise bereits während des Füllvorgangs wieder freigegeben. Die notwendige Taktzeit für diesen Füllvorgang wird auf diese Weise reduziert, da nicht mehr ein Wegschwenken der Zusatzbacken abgewartet werden muss, wenn der Füllvorgang beendet ist. Gleichzeitig wird eine Faltenfreiheit bzw. eine Reduktion eines Faltenrisikos im Greifabschnitt zur Verfügung gestellt. Dies gelingt durch das definierte Glattziehen und Spannen des Sackabschnitts zwischen dem Klemmabschnitt und dem Zusatzklemmabschnitt.In particular, by the formation of the clamping device according to the invention brings a method according to the invention with the same advantages, as they have been explained in detail. Thus, during the filling process by closing the Additional baking prior to filling already done opening the additional jaws. The transport path for a subsequent removal of the filled bag section using the gripping device is released in this way during the filling process again. The necessary cycle time for this filling process is reduced in this way, since no more pivoting away the additional jaws must be awaited when the filling process is completed. At the same time a freedom from wrinkles or a reduction of a wrinkle risk in the gripping portion is provided. This is achieved by the defined smooth drawing and tensioning of the bag section between the clamping section and the additional clamping section.

Ein erfindungsgemäßes Verfahren lässt sich dahingehend weiterbilden, dass zum Öffnen der beiden Zusatzbacken die erste Zusatzbacke, welche in Transportrichtung des Sackabschnitts der zweiten Zusatzbacke nachgeordnet ist, zuerst, insbesondere ausschließlich, bewegt wird. Die Beschleunigung des Taktes erfolgt also hier noch verbessert, da ein Öffnen der ersten Zusatzbacke in Transportrichtung und damit in Laufrichtung des Sackabschnitts erfolgt. Für den Abtransport mithilfe der Greifvorrichtung für den Sackabschnitt spielt insbesondere diese angeordnete erste Zusatzbacke eine wesentliche Rolle, um die Taktzeit der Füllstation der Sackfüllanlage signifikant zu reduzieren.A method according to the invention can be further developed such that the first additional jaw, which is arranged downstream in the direction of transport of the bag section of the second additional jaw, is first, in particular exclusively, moved to open the two additional jaws. The acceleration of the clock is thus still improved here, since an opening of the first additional jaw takes place in the transport direction and thus in the direction of the bag section. For the removal by means of the gripping device for the bag section, in particular, this arranged first additional jaw plays an essential role in order to significantly reduce the cycle time of the filling station of the bag filling system.

Fig. 1 zeigt schematisch eine Sackfüllanlage 100, bei welcher ausgehend von einer rechts angeordneten Vorlagerolle über eine Puffervorrichtung eine Folienbahn 200 abgewickelt wird. Diverse Stationen 170 dienen dazu, eine Bearbeitung der Folienbahn 200 durchzuführen. Dies sind von rechts nach links eine erste Station 170 als Ablängstation mit einer Schneidvorrichtung und Bodennahtsiegelstation, nachfolgend die Füllstation 110, nachfolgend eine Kopfnahtsiegelstation 170 und finalisierend eine Kopfnahtkühlstation als Station 170.

In der Füllstation 110 wird über einen Trichter Schüttgut in den Sackabschnitt 210 eingefüllt. An dieser Stelle ist auch die erfindungsgemäße Klemmvorrichtung 10 mit einer Klemmbackenvorrichtung 20 und einer Zusatzklemmvorrichtung 30 angeordnet. Fig. 1 schematically shows a bag filling plant 100, in which, starting from a right Vorlagerolle via a buffer device, a film web 200 is unwound.

Fig. 2 zeigt in seitlich gedrehter Weise den Sackabschnitt 210 in der Füllstation 110. Nach oben gerichtet ist das Kopfende 214 und nach unten gerichtet das Bodenende 216. Unterhalb des Kopfendes 214 erstreckt sich der Kopfbereich 212 des Sackabschnitts 210. Bei der Ausführungsform der Fig. 2 sind links und rechts jeweils eine erfindungsgemäße Klemmvorrichtung 10 mit jeweils einer Klemmbackenvorrichtung 20 und einer Zusatzklemmvorrichtung 30 vorgesehen. Ebenfalls ist gut zu erkennen, dass zwischen der Klemmbackenvorrichtung 20 und der Zusatzklemmvorrichtung 30 eine Greifvorrichtung 40 den Sackabschnitt 210 greifen kann. Fig. 2 In a laterally rotated manner, the sack portion 210 in the filling station 110 is shown. The head end 214 is directed upwards and the bottom end 216 is directed downwards. Below the head end 214, the head portion 212 of the sack portion 210 extends Fig. 2 are left and right respectively a clamping device 10 according to the invention, each with a jaw device 20 and a Additional clamping device 30 is provided. It can also be clearly seen that a gripping device 40 can grip the bag section 210 between the clamping jaw device 20 and the auxiliary clamping device 30.

In den Fig. 3 und 4 sind schematisch die einzelnen Greifabschnitte zu erkennen. So wird eine Klemmung mittels der Klemmvorrichtung 20 im Klemmabschnitt 26 im Kopfbereich 212 des Sackabschnitts 210 zur Verfügung gestellt. Die Zusatzklemmvorrichtung 30 klemmt in einem Zusatzklemmabschnitt 36 den Sackabschnitt 210. Zwischen den Klemmabschnitt 26 und dem Zusatzklemmabschnitt 36 ist ein Abstand vorgesehen, in welchem der Greifabschnitt 46 für die Greifvorrichtung 40 angeordnet ist. Dies wird insbesondere in der Ansicht der beiden Fig. 3 und 4 deutlich.In the 3 and 4 are schematically recognize the individual gripping sections. Thus, a clamping by means of the clamping device 20 in the clamping portion 26 in the head portion 212 of the bag portion 210 is provided. The auxiliary clamping device 30 clamps the bag section 210 in an additional clamping section 36. Between the clamping section 26 and the additional clamping section 36 there is provided a spacing in which the gripping section 46 for the gripping device 40 is arranged. This is especially true in the view of the two 3 and 4 clear.

Die Fig. 5 bis 10 beschreiben den Vorgang der Klemmung während des Füllvorgangs in der Füllstation 110. So ist hier eine Klemmvorrichtung 10 in der seitlichen Darstellung gezeigt. Diese weist eine Klemmvorrichtung 20 und eine Zusatzklemmvorrichtung 30 auf. Die Klemmvorrichtung 20 ist mit einer stationär zu einem Rahmen 12 ausgebildeten ersten Klemmbacke 22 versehen. Bewegbar rotatorisch gelagert am Rahmen 12 ist eine zweite Klemmbacke 24 vorgesehen, welche auch über einen Klemmantrieb 28 verfügt.The Fig. 5 to 10 describe the process of clamping during the filling process in the filling station 110. Thus, a clamping device 10 is shown in the side view. This has a clamping device 20 and an additional clamping device 30. The clamping device 20 is provided with a stationary to a frame 12 formed first jaw 22. Movable rotatably mounted on the frame 12, a second jaw 24 is provided, which also has a clamping drive 28.

Die Zusatzklemmvorrichtung 30 ist mit einer rotatorisch an der ersten Klemmbacke 22 angeordneten und gelagerten ersten Zusatzbacke 32 versehen. Der Antrieb dieser Rotationsbewegung erfolgt über einen Zusatzantrieb 38. Auf der gegenüberliegenden Seite des Sackabschnitts 210 ist eine zweite Zusatzbacke 34 vorgesehen, welche über einen Lagerabschnitt 50 stationär und damit bewegungsfest relativ an der zweiten Klemmbacke 24 befestigt ist. Auch ist gut die Korrelation zur Transportrichtung T zu erkennen, sodass erste Klemmbacke 22 und die erste Zusatzbacke 32 in Transportrichtung T dem Sackabschnitt 210 nachgelagert sind.The additional clamping device 30 is provided with a rotatably mounted on the first jaw 22 and stored first auxiliary jaw 32. The drive of this rotational movement via an additional drive 38. On the opposite side of the bag portion 210, a second additional jaw 34 is provided, which is fixedly mounted on a bearing portion 50 and thus immobile relative to the second jaw 24. Also, the correlation to the transport direction T can be seen well, so that the first jaw 22 and the first additional jaw 32 are downstream of the bag section 210 in the transport direction T.

In Fig. 5 ist die Startsituation gezeigt, nachdem der Sackabschnitt 210 in die Füllstation 110 eingebracht worden ist. Anschließend erfolgt über den Klemmantrieb 28 ein Schließen der Klemmbacke 22, wie dies die Fig. 6 zeigt. Damit wird automatisch auch die zweite Zusatzbacke 34 in die Position für die Klemmung bewegt. Anschließend erfolgt über den Zusatzantrieb 38 ein Klemmen auch im Zusatzklemmabschnitt 36 durch die Bewegung der ersten Zusatzbacke 32.In Fig. 5 the starting situation is shown after the bag section 210 has been introduced into the filling station 110. Subsequently, via the clamping drive 28, a closing of the jaw 22, as the Fig. 6 shows. This automatically moves the second additional jaw 34 in the position for the clamping. Subsequently, via the Additional drive 38 terminals in the additional clamping section 36 by the movement of the first additional jaw 32nd

In der Position, wie sie die Fig. 7 zeigt, herrscht nun eine faltenfreie und gespannte Positionierung des Sackabschnitts 210 zwischen der Klemmvorrichtung 20 und der Zusatzklemmvorrichtung 30 vor. Nun kann im Abstand zwischen diesen beiden Vorrichtungen 20 und 30 ein Greifen mithilfe der Greifvorrichtung 40 erfolgen, wie dies die Fig. 8 zeigt. Zu diesem Zeitpunkt ist es nun möglich, dass die erste Zusatzbacke 32 bereits öffnet, wie es die Fig. 9 zeigt. Die Befestigung und Klemmung mithilfe der Klemmvorrichtung 20 bleibt hiervon unberührt, sodass die erste Zusatzbacke 32 bereits den Transportweg für eine nachfolgende Pendeltransportbewegung der Greifvorrichtung 40 freigibt. Erst nach Beenden des Füllvorgangs schwenkt auch über den Klemmantrieb 38 die zweite Klemmbacke 24 wieder auf, sodass nunmehr der Sackabschnitt 210 für den Abtransport mithilfe der Greifvorrichtung 40 komplett freigegeben ist.In the position, like the Fig. 7 now shows a wrinkle-free and tense positioning of the bag portion 210 between the clamping device 20 and the auxiliary clamping device 30 before. Now, in the distance between these two devices 20 and 30, a gripping using the gripping device 40 take place, as the Fig. 8 shows. At this time, it is now possible that the first additional jaw 32 already opens, like the Fig. 9 shows. The attachment and clamping by means of the clamping device 20 remains unaffected, so that the first additional jaw 32 already releases the transport path for a subsequent pendulum transport movement of the gripping device 40. Only after completion of the filling process also pivots on the clamping drive 38, the second jaw 24 again, so now the bag section 210 is completely released for removal by means of the gripping device 40.

Fig. 11 zeigt in perspektivischer Darstellung schematisch, wie ein bogenförmiger Verlauf des Lagerabschnitts 50 ausgebildet sein kann. So erfolgt hier die Lagerung zwischen den beiden Backen, also der zweiten Klemmbacke 24 und der zweiten Zusatzbacke 34, über den bogenförmigen Lagerabschnitt 50, welcher hier sogar abgehoben von einem nicht dargestellten Sackabschnitt 210 ausgebildet ist. Fig. 11 shows in perspective view schematically how an arcuate course of the bearing portion 50 may be formed. So here is the storage between the two jaws, so the second jaw 24 and the second additional jaw 34, on the arcuate bearing portion 50, which is here even lifted from a bag section 210, not shown formed.

Die voranstehende Erläuterung der Ausführungsformen beschreibt die vorliegende Erfindung ausschließlich im Rahmen von Beispielen. Selbstverständlich können einzelne Merkmale der Ausführungsformen, sofern technisch sinnvoll, frei miteinander kombiniert werden, ohne den Rahmen der vorliegenden Erfindung zu verlassen.The above explanation of the embodiments describes the present invention solely by way of example.
