Description

Die Erfindung betrifft eine Verarbeitungsvorrichtung für Folienbeutel umfassend mehrere nebeneinander angeordnete Beutelaufnahmen, die jeweils zum Aufnehmen und Transportieren eines Folienbeutels ausgebildet sind, und mehrere in Transportrichtung hintereinander angeordnete Paare gegenüberliegender Rampen, entlang derer die Beutelaufnahmen im Betrieb geführt transportiert werden, wobei der Abstand gegenüberliegender Rampen die Breite der Beutelaufnahmen definiert. So eine Vorrichtung ist z.B. aus dem Dokument EP 2 113 462 A1 bekannt.The invention relates to a processing device for film bag comprising a plurality of juxtaposed bag receptacles, each formed for receiving and transporting a film bag, and a plurality of successively arranged in the transport direction pairs of opposite ramps along which the bag receptacles are guided in operation, wherein the distance of opposite ramps Width of the bag holders defined. Such a device is eg from the document EP 2 113 462 A1 known.

Eine Verarbeitungsvorrichtung für Folienbeutel, beispielsweise eine Füllmaschine, erfordert prozessbedingt, dass das Öffnungsmaß der Folienbeutel entlang der Transportstrecke geändert wird. Beispielsweise sind Folienbeutel bei der Zuführung in die Beutelaufnahme flach und maximal breit. Für eine optimale Befüllung sollen die Folienbeutel hingegen unter der Dosierung maximal geöffnet sein. Diese Unterschiede im Öffnungsmaß werden über die seitlich der angeordneten Rampen eingestellt. Da die Beutelbreite sich in Transportrichtung ändern soll, müssen mehrere in Transportrichtung hintereinander angeordnete Rampen verwendet werden. Die Rampen werden jeweils vor der Inbetriebnahme separat manuell entsprechend dem jeweils einzustellenden Öffnungsmaß in den unterschiedlichen Prozessbereichen eingestellt. Neben den verschiedenen Einstellungen für das geeignete Öffnungsmaß müssen die Rampen auch separat manuell eingestellt werden, wenn ein Formatwechsel bei den Folienbeuteln eine andere Kastenbreite erforderlich macht. Das Einstellen der Kastenbreite ist aufgrund der zahlreichen Stellglieder mit einem großen Aufwand verbunden.A processing device for foil bags, for example a filling machine, requires, as a result of the process, that the opening dimension of the foil bags be changed along the transport path. For example, foil bags are flat and maximally wide when fed into the bag receptacle. For optimum filling, however, the film bags should be maximally open under the dosage. These differences in opening size are set via the side of the arranged ramps. Since the bag width is to change in the transport direction, several in the transport direction successively arranged ramps must be used. The ramps are each set manually before commissioning separately according to the particular opening size to be set in the different process areas. In addition to the different settings for the appropriate opening size, the ramps must also be set manually separately if a format change in the film bags requires a different box width. Setting the box width is associated with a great deal of effort due to the numerous actuators.

Es ist also Aufgabe der Erfindung, eine Verarbeitungsvorrichtung für Folienbeutel bereit zu stellen, die eine vereinfachte Anpassung an das Folienformat und das Öffnungsmaß der Folienbeutel ermöglicht.It is therefore an object of the invention to provide a processing device for film bag, which allows a simplified adaptation to the film size and the opening dimension of the film bag.

Das Problem wird dadurch gelöst, dass die Verarbeitungsvorrichtung eine Verstelleinrichtung umfasst, die zum automatischen Verstellen des Abstands quer zur Transportrichtung zwischen gegenüberliegenden Rampen ausgebildet ist.The problem is solved in that the processing device comprises an adjusting device, which is designed for automatically adjusting the distance transversely to the transport direction between opposite ramps.

Unter Verstellen des Abstandes kann auch verstanden werden, dass die Rampen zueinander schräg gestellt werden. In diesem Fall ändert sich der Abstand quer zur Transportrichtung nicht entlang der gesamten Rampen.By adjusting the distance can also be understood that the ramps are mutually inclined. In this case, the distance across the transport direction does not change along the entire ramps.

Die Verarbeitungsvorrichtung kann beispielsweise Behandlungseinrichtungen umfassen und Folienbeutel können von Magazinen zu den verschiedenen Behandlungseinrichtungen transportiert werden, wo diese zum Beispiel mit einem Produkt gefüllt oder verschlossen werden können.For example, the processing device may include treatment devices, and foil bags may be transported from magazines to the various processing devices where they can be filled or closed with a product, for example.

Das automatische Verstellen kann beispielsweise mittels Motoren, beispielsweise Elektromotoren, und gegebenenfalls Kopplungs- und Übersetzungselementen und/oder Steuerungselemente erfolgen.The automatic adjustment can be done for example by means of motors, such as electric motors, and optionally coupling and translation elements and / or control elements.

Ein manuelles Einstellen der Abstände ist damit nicht mehr nötig, was eine vereinfachte Anpassung an das Folienformat und das Öffnungsmaß der Folienbeutel ermöglicht.A manual setting of the distances is thus no longer necessary, which allows a simplified adaptation to the film size and the opening dimension of the foil bag.

Ein Paar gegenüberliegende Rampen können insbesondere derart ausgebildet und angeordnet sein, dass die beiden Rampen gleich lang und entlang der Transportrichtung nicht gegeneinander versetzt sind.A pair of opposed ramps may in particular be designed and arranged such that the two ramps are of equal length and not offset from one another along the transport direction.

Das Verstellen des Abstands zwischen zwei gegenüberliegenden Rampen erfolgt durch ein Verstellen der Position mindestens einer der beiden Rampen. Vorzugsweise erfolgt das Verstellen des Abstands, indem beide gegenüberliegenden Rampen in entgegengesetzte Richtungen quer zur Transportrichtung verschoben werden. Der Vorteil ist, dass dann beim Umstellen der Abstände kein Versatz quer zur Transportrichtung auftritt.The adjustment of the distance between two opposite ramps by adjusting the position of at least one of the two ramps. Preferably, the adjustment of the distance takes place by both opposite ramps are moved in opposite directions transverse to the transport direction. The advantage is that then when changing the distances no offset occurs transversely to the transport direction.

Die Rampen können jeweils unabhängig voneinander einstellbar sein. Das heißt, dass die Positionen verschiedener Rampen individuell eingestellt werden können bzw. dass nicht zwangsläufig alle Rampen gleich eingestellt werden müssen.The ramps can each be independently adjustable. This means that the positions of different ramps can be set individually or that not all ramps have to be set the same.

Die Rampen können einteilig gestaltet sein oder aus mehreren Segmenten, die untereinander mit Drehgelenken verbunden sind, bestehen. Die Rampen oder Rampensegmente können parallel oder zur Transportrichtung geneigt verlaufen.The ramps can be designed in one piece or consist of several segments, which are interconnected with swivel joints exist. The ramps or ramp segments may run parallel or inclined to the transport direction.

Mehrere Rampen können mit einer gemeinsamen Verstelleinrichtung gekoppelt sein. Die Versteileinrichtung kann einen Antrieb zum gemeinsamen Verstellen mehrerer mit der Verstelleinrichtung gekoppelter Rampen umfassen, insbesondere für mehrere hintereinander angeordnete Rampen.Several ramps may be coupled to a common adjustment device. The adjusting device may comprise a drive for the common adjustment of a plurality of ramps coupled to the adjusting device, in particular for a plurality of ramps arranged one behind the other.

Insbesondere können alle Rampen auf einer Seite mit einer ersten gemeinsamen Verstelleinrichtung gekoppelt sein und alle Rampen auf der anderen Seite können mit einer zweiten gemeinsamen Verstelleinrichtung gekoppelt sein. Die beiden Verstelleinrichtungen können einen gemeinsamen Antrieb oder separate Antriebe umfassen.In particular, all ramps on one side may be coupled to a first common adjustment device and all the ramps on the other side may be coupled to a second common adjustment device. The two adjusting devices may comprise a common drive or separate drives.

Mit einer gemeinsamen Verstelleinrichtung gekoppelte Rampen können durch individuelle, insbesondere mechanische, Koppelung unabhängig voneinander verstellbar sein.Ramps coupled to a common adjusting device can be adjusted independently of one another by individual, in particular mechanical, coupling.

Für mehrere hintereinander angeordnete Rampen kann also ein gemeinsamer Antrieb vorgesehen sein, mit dem die jeweilige Position jeder Rampe quer zur Transportrichtung individuell eingestellt werden kann.For a plurality of successively arranged ramps so a common drive can be provided with which the respective position of each ramp can be adjusted individually to the transport direction.

Somit werden die Anzahl der Antriebe und Steuerungselemente reduziert, so dass eine vereinfachte Anpassung der Vorrichtung an das Folienformat und das Öffnungsmaß der Folienbeutel möglich ist.Thus, the number of drives and control elements are reduced, so that a simplified adaptation of the device to the film size and the opening dimension of the film bag is possible.

Alternativ oder zusätzlich kann die Verstelleinrichtung mehrere Antriebe umfassen, die jeweils eine oder mehrere Rampen verstellen und mit einer zentralen Steuereinrichtung derart verbunden sind, dass sie im Betrieb von dieser gesteuert werden. Dies ermöglicht eine besonders feine Abstimmung und Anpassung der Kastenbreite, beispielsweise für ungewöhnliche Beutelformate.Alternatively or additionally, the adjusting device may comprise a plurality of drives, which each adjust one or more ramps and are connected to a central control device in such a way that they are controlled by the latter during operation. This allows a particularly fine tuning and adjustment of the box width, for example, for unusual bag formats.

Die Verstelleinrichtung kann eine, insbesondere parallel zur Transportrichtung angeordnete, Verstellstange umfassen, die mittels mehrerer Stellglieder mit mehreren hintereinander angeordneten Rampen gekoppelt ist. Die Stellglieder können beispielsweise in Form von Kulissen ausgebildet sein.The adjusting device may comprise an adjusting rod, which is arranged in particular parallel to the transport direction and which is coupled by means of a plurality of actuators to a plurality of ramps arranged one behind the other. The actuators may be formed, for example in the form of scenes.

Die Stellglieder können insbesondere derart ausgebildet sein, dass eine Bewegung der Verstellstange parallel zur Transportrichtung in eine Bewegung der Rampen quer zur Transportrichtung übersetzt wird. Andere Freiheitsgrade der Bewegung der Rampen und der Verstellstange können optional gesperrt sein. Eine Rampe kann entlang ihrer gesamten Länge gleich weit quer zur Transportrichtung verschoben werden. Es ist auch möglich, dass nur ein Teil einer Rampe quer zur Transportrichtung verschoben wird oder dass verschiedene Bereiche der Rampe unterschiedlich weit verschoben werden. So kann beispielsweise eine Schrägstellung erfolgen.The actuators may in particular be designed such that a movement of the adjusting rod is translated parallel to the transport direction in a movement of the ramps transversely to the transport direction. Other degrees of freedom of movement of the ramps and the adjustment rod may optionally be disabled. A ramp can be moved along its entire length equally far transversely to the transport direction. It is also possible that only a part of a ramp is moved transversely to the transport direction or that different areas of the ramp are moved differently far. For example, an inclination can occur.

Die Verstellstange kann an der den Beutelaufnahmen abgewandten Seite mehrerer hintereinander angeordneten Rampen und parallel zu den Rampen angeordnet sein. Die Verstellstange kann einstückig ausgebildet sein oder aus mehreren aneinander befestigten Stangen bestehen.The adjusting rod may be arranged on the side facing away from the bag receptacles of a plurality of successively arranged ramps and parallel to the ramps. The adjusting rod may be formed in one piece or consist of several rods attached to each other.

Die Verarbeitungsvorrichtung kann Führungselemente umfassen, die derart ausgebildet und mittels denen die Verstellstange und die Rampen derart geführt sind, dass die Verstellstange nur parallel zur Transportrichtung bewegbar ist und die Rampen mindestens, insbesondere nur, quer zur Transportrichtung bewegbar sind. Als Führungselemente können Elemente verwendet werden, mit bzw. auf denen die Rampen bzw. Verstellstange gelagert sind. Alternativ oder zusätzlich können die Stellglieder Elemente aufweisen, die ebenfalls als Führungselemente dienen.The processing device may comprise guide elements which are formed and by means of which the adjusting rod and the ramps are guided such that the adjusting rod is movable only parallel to the transport direction and the ramps are movable at least, in particular only, transversely to the transport direction. As guide elements elements can be used be, with or on which the ramps or adjustment are stored. Alternatively or additionally, the actuators may comprise elements which also serve as guide elements.

Die Verstelleinrichtung kann derart ausgebildet sein, dass die Positionen der Rampen quer zur Transportrichtung und ihre Ausrichtungen durch Verstellen der Position der Verstellstange parallel zur Transportrichtung eingestellt werden.The adjusting device can be designed such that the positions of the ramps transversely to the transport direction and their orientations are adjusted by adjusting the position of the adjusting rod parallel to the transport direction.

Die Stellglieder können derart ausgebildet sein, dass ihre Übersetzung begrenzt, wie weit die Rampen quer zur Transportrichtung bewegt werden können. Die Positionsverstellung quer zur Transportrichtung bzw. eine Änderung der Ausrichtung (beispielsweise Schrägstellung) hängt also von den für die jeweilige Rampe oder Rampenabschnitt verwendeten Stellgliedern ab. Die Stellglieder können derart ausgebildet sein, dass die Position diskret oder kontinuierlich verstellt wird.The actuators may be designed so that their translation limits how far the ramps can be moved transversely to the transport direction. The position adjustment transversely to the transport direction or a change in orientation (for example, inclined position) thus depends on the actuators used for the respective ramp or ramp section. The actuators can be designed such that the position is discretely or continuously adjusted.

Die Verstelleinrichtung kann derart ausgebildet sein, dass verschiedene Rampen oder Rampenabschnitte mittels Stellgliedern mit unterschiedlicher Übersetzung mit der Verstellstange gekoppelt sind. Die Verstelleinrichtung kann so ausgebildet sein, dass die Positionen der Rampen, insbesondere quer zur Transportrichtung, und deren Ausrichtung gemäß der Übersetzung der jeweiligen Stellglieder, eingestellt werden, insbesondere durch Verstellen der Position der Verstellstange.The adjusting device can be designed such that different ramps or ramp sections are coupled by means of actuators with different translation with the adjusting rod. The adjusting device can be designed so that the positions of the ramps, in particular transversely to the transport direction, and their orientation according to the translation of the respective actuators, are adjusted, in particular by adjusting the position of the adjusting rod.

An einer Rampe können mehrere Stellglieder mit unterschiedlichen Stellgrößen angreifen. In diesem Fall wird die Rampe an verschiedenen Stellen in unterschiedlichem Maß quer zur Transportrichtung verschoben. So kann sie beispielsweise von einer Stellung parallel zur Transportrichtung in eine Schrägstellung gebracht werden. In diesem Fall ist die Länge der Rampe in Laufrichtung veränderlich und kann vorzugsweise bei der Verstellung kompensiert werden.On a ramp several actuators can attack with different variables. In this case, the ramp is moved at different locations in different degrees transversely to the transport direction. Thus, it can be brought, for example, from a position parallel to the transport direction in an inclined position. In this case, the length of the ramp is variable in the direction of travel and can preferably be compensated during the adjustment.

Pro Rampe kann mindestens ein Führungselement ortsfest gelagert sein. Bei Rampen bzw. Rampensegmenten, die immer parallel verlaufen sollen, können alle angreifenden Führungselemente ortsfest und nicht rotierbar ausgeführt sein. Bei nicht oder nicht immer parallel verlaufenden Rampen bzw. Rampensegmenten sind die von der oben beschriebenen Längenänderung betroffenen Führungselemente drehbar gelagert, jedoch nicht verschiebbar. Darüber hinaus ist dann auch die Anbindung der entsprechenden Stellelemente an die Rampen drehbar. Alternativ können die Führungselemente ortsfest und nicht rotierbar sein und es kann eine zusätzliche Führung zur Anbindung an die Rampen vorgesehen sein.Per ramp, at least one guide element can be stored stationary. In ramps or ramp segments, which should always be parallel, all attacking guide elements can be made stationary and not rotatable. When not or not always parallel ramps or ramp segments concerned by the above-described change in length guide elements are rotatably mounted, but not displaced. In addition, then the connection of the corresponding control elements to the ramps is rotatable. Alternatively, the guide elements can be stationary and not rotatable, and an additional guide for connection to the ramps can be provided.

Die Verstelleinrichtung kann einen bzw. den Antrieb umfassen, der derart ausgebildet ist, dass er die Verstellstange direkt antreibt und diese parallel zur Transportrichtung bewegt. Wie oben erwähnt kann alternativ oder zusätzlich für eine oder mehrere Rampen ein eigener Antrieb vorgesehen sein, der diese direkt antreibt und verstellt.The adjusting device may comprise one or the drive which is designed such that it drives the adjusting rod directly and moves it parallel to the transport direction. As mentioned above, alternatively or additionally, one or more ramps may be provided with a dedicated drive which directly drives and adjusts them.

Eine Reihe von Beutelaufnahmen kann beispielsweise folgendermaßen gebildet werden. An einem ersten Querbalken sind mehrere Halteelemente nebeneinander befestigt, die jeweils ein Greifelement, beispielsweise in Form einer Klammer, und Seitenstützelement mit Aufnahmen umfasst, wobei die Öffnung aller Klammern und alle Aufnahmen in die gleiche Richtung weisen. An einem zweiten Querbalken sind genauso viele Halteelemente befestigt wie an dem ersten Querbalken. Ihre Aufnahmen und Klammern weisen in die entgegengesetzte Richtung wie die des ersten Querbalkens. Die beiden Querbalken sind im Betrieb derart parallel zueinander und quer zur Transportrichtung angeordnet, dass die Halteelemente kammartig angeordnet werden. Das heißt, dass ihre Aufnahmen und Greifelemente aufeinander zu weisen und dass je ein Halteelement des ersten Querbalkens und ein Halteelement des zweiten Querbalkens Teil der gleichen Beutelaufnahme sind. Jedem Paar von Halteelementen kann ein Boden zum Stützen der Beutel von unten zugeordnet sein.For example, a series of bag receptacles may be formed as follows. On a first cross bar a plurality of retaining elements are fastened side by side, each comprising a gripping element, for example in the form of a clip, and side support member with recordings, wherein the opening of all staples and all recordings have in the same direction. On a second crossbar as many retaining elements are attached as on the first crossbar. Their recordings and brackets point in the opposite direction as the first crossbeam. During operation, the two transverse beams are arranged parallel to one another and transversely to the transport direction in such a way that the holding elements are arranged in a comb-like manner. This means that their receptacles and gripping elements face each other and that each one holding element of the first crossbar and one holding element of the second crossbar are part of the same bag receptacle. Each pair of retaining elements may be associated with a bottom for supporting the bags from below.

Der erste Querbalken wird im Betrieb entlang mehrerer hintereinander liegender Rampen in Transportrichtung geführt und der zweite Querbalken wird im Betrieb entlang der Rampen synchron mit dem ersten Querbalken geführt. Indem eine oder beide Rampen eines Paars von ersten und zweiten Rampen quer zur Transportrichtung so verschoben werden, dass sich der Abstand der an den entsprechenden Querbalken befestigten Halteelemente ändert, wird die Breite der Beutelaufnahmen geändert. So können die Beutelaufnahmen an unterschiedliche Beutelformate angepasst werden oder das Öffnungsmaß der Beutel kann eingestellt werden.The first crossbar is guided in operation along several consecutive ramps in the transport direction and the second crossbar is guided in operation along the ramps synchronously with the first crossbar. By displacing one or both ramps of a pair of first and second ramps transversely to the transport direction such that the distance of the holding elements attached to the respective crossbar changes, the width of the bag receivers is changed. Thus, the bag receivers can be adapted to different bag formats or the opening size of the bag can be adjusted.

Die Beutelaufnahmen können beispielsweise wie in der EP 2 113 462 A1 ausgebildet sein.The bag receptacles, for example, as in the EP 2 113 462 A1 be educated.

Figur 1 zeigt eine Draufsicht auf eine erste Ausführungsform einer Verarbeitungsvorrichtung 1 für Folienbeutel 2. Bei den Folienbeuteln handelt es sich um Folienbeutel, die an einer Seite (der Oberseite) offen und an allen anderen Seiten verschlossen sind. Die der Oberseite gegenüberliegende Seite der Folienbeutel wird als Boden bezeichnet. Die offene Oberseite weist im Transport nach oben, der Boden nach unten. Hier sei angemerkt, dass der Folienbeutel im Bodenbereich derart gefaltet sein kann, dass bei einem Auffalten des Folienbeutels ein Standboden entsteht. Die Folienbeutel können beispielsweise im flachen Zustand rechteckig sein. FIG. 1 shows a plan view of a first embodiment of a processing apparatus 1 for foil pouch 2. The foil pouches are foil pouches which are open on one side (the top) and closed on all other sides. The top side opposite side of the foil bag is referred to as the bottom. The open top points in the transport up, the ground down. It should be noted here that the foil bag can be folded in the bottom area in such a way that when the foil bag unfolds, a floor is produced. The foil pouches can be rectangular, for example when flat.

Die Figur zeigt beispielhaft ein Magazinsystem 3 mit nebeneinander angeordneten Folienbeutelmagazinen in Form von Magazinschächten. Im Betrieb werden Folienbeutel von oben in die Magazinschächte gestapelt und unten entnommen. Der Schritt, in dem die Folienbeutel aus den Folienbeutelmagazinen an die Beutelaufnahmen übergeben werden, umfasst, dass aus allen Magazinschächten gleichzeitig je ein Folienbeutel an je eine Beutelaufnahme übergeben wird. Das Übergeben erfolgt maschinell, beispielsweise mittels eines hier nicht gezeigten Saugmechanismus. Es kann jedoch auch eine beliebige andere Bestückung der Beutelaufnahmen erfolgen. Die gleichzeitig bestückten Beutelaufnahmen bilden eine Reihe nebeneinander angeordneter Beutelaufnahmen. Die bestückten Beutelaufnahmen werden nebeneinander synchron in Transportrichtung 5 bewegt. Das heißt, die Reihe von Beutelaufnahmen ist quer zur Transportrichtung angeordnet. Die Beutelaufnahmen können somit gleichzeitig nebeneinander angeordnete Folienbeutel transportieren.The figure shows an example of a magazine system 3 with juxtaposed foil bag magazines in the form of magazine shafts. In operation, foil bags are stacked from above into the magazine shafts and removed below. The step in which the foil bags are transferred from the foil bag magazines to the bag receptacles comprises that a foil bag is transferred to each bag receptacle from all the magazine wells at the same time. The transfer is done by machine, for example by means of a suction mechanism not shown here. However, it can also be done any other placement of the bag receptacles. The simultaneously loaded bag receivers form a row of juxtaposed bag receivers. The stocked bag receivers are synchronously moved in the transport direction 5 side by side. That is, the row of bag receptacles is arranged transversely to the transport direction. The bag receivers can thus simultaneously transport juxtaposed foil bags.

Die Beutelaufnahmen umfassen Halteelemente. Jedes Halteelement umfasst ein Greifelement in Form einer Klammer 6a und ein Seitenstützelement (hier nicht gezeigt). Dieses kann eine Aufnahme aufweisen, die beispielsweise eine schlitzförmige, nach oben, unten und zu den Folienbeuteln hin offene Führung sein kann. Die Führung kann, wie hier gezeigt, abgeschrägte Wände oder alternativ parallel stehende Wände aufweisen. Im Betrieb werden die Folienbeutel von oben in die Führungen eingeführt und sind dann darin seitlich gestützt. Durch die Aufnahmeelemente wird eine seitliche Bewegung der Folienbeutel und in diesem Beispiel auch eine Bewegung in bzw. gegen die Transportrichtung beschränkt. Die Beutel werden hier beispielsweise von unten durch einen Boden der Aufnahme gestützt, können jedoch alternativ auch durch höhenverstellbare Stützelemente gestützt werden. Die Klammern greifen die Folienbeutel seitlich an deren oberen Ende und können diese beim hängenden Transport halten und beispielsweise auch verschließen.The bag receivers comprise holding elements. Each retaining element comprises a gripping element in the form of a clamp 6a and a side support element (not shown here). This may have a receptacle, which may be, for example, a slot-shaped, up, down and to the foil bags open guide. The guide may, as shown here, have slanted walls or alternatively parallel walls. In operation, the foil bags inserted from above into the guides and are then laterally supported therein. By the receiving elements a lateral movement of the foil bag and in this example, a movement in or against the transport direction is limited. The bags are supported here, for example, from below by a bottom of the receptacle, but can alternatively be supported by height-adjustable support elements. The brackets grip the foil bag laterally at the upper end and can hold them during hanging transport and, for example, also close.

Die Abstände der Halteelemente sind verstellbar und werden entsprechend der Breite b der jeweils verarbeiteten Folienbeutel eingestellt. Bei der Übergabe aus den Folienbeutelmagazinen sind die Folienbeutel flach und haben somit ihre maximale Breite. Die Halteelemente sind zu diesem Zeitpunkt in einem Abstand b angeordnet, der etwa der maximalen Breite entspricht, vorzugsweise in einem Abstand, der etwas breiter ist als die maximalen Breite, so dass die Folienbeutel problemlos in die Beutelaufnahmen eingeführt und in diesen sicher seitlich gestützt werden können. Auf dem Transportweg kann optional der Abstand der Halteelemente reduziert werden. Dadurch können die Folienbeutel an ihrer Oberseite geöffnet werden, zum Beispiel, um eine Flüssigkeit einzufüllen.The distances between the holding elements are adjustable and are adjusted according to the width b of each processed foil bag. When transferring from the foil bag magazines, the foil bags are flat and thus have their maximum width. The holding elements are arranged at this time at a distance b which corresponds approximately to the maximum width, preferably at a distance which is slightly wider than the maximum width, so that the film bag can be easily inserted into the bag receptacles and securely supported laterally in these , On the way to transport optionally the distance of the holding elements can be reduced. This allows the foil pouches to be opened at their top, for example, to fill a liquid.

An einem ersten Querbalken 7a sind mehrere Halteelemente, deren Aufnahmen und Klammern in die gleiche Richtung weisen nebeneinander befestigt. An einem zweiten Querbalken 7b sind genauso viele Halteelemente befestigt wie an dem ersten Querbalken. Ihre Aufnahmen und Klammern weisen jedoch in die entgegengesetzte Richtung. Die Querbalken sind im Betrieb derart parallel zueinander und quer zur Transportrichtung angeordnet, dass die Halteelemente kammartig angeordnet werden. Das heißt, dass ihre Aufnahmen und Klammern aufeinander zu weisen und dass je ein Halteelement des ersten Querbalkens und ein Halteelement des zweiten Querbalkens Teil der gleichen Beutelaufnahme sind.At a first crossbar 7a are a plurality of retaining elements whose receptacles and brackets in the same direction have side by side. On a second crossbar 7b as many retaining elements are attached as on the first crossbar. Their recordings and brackets, however, point in the opposite direction. During operation, the transverse beams are arranged parallel to one another and transversely to the transport direction in such a way that the holding elements are arranged in a comb-like manner. This means that their receptacles and brackets face each other and that each holding element of the first crossbar and a holding element of the second crossbar are part of the same bag receptacle.

In der Figur sind mehrere erste Querbalken und zweite Querbalken gezeigt. Ein oder mehrere erste Querbalken werden im Betrieb entlang mehrerer hintereinander liegender Rampen 8a, die in diesem Beispiel parallel zur Transportrichtung angeordnet sind geführt. Die zweiten Querbalken werden im Betrieb entlang gegenüberliegenden Rampen 8b synchron mit den ersten Querbalken geführt. In der Figur sind mehrere Paare von ersten Rampen und zweiten Rampen, die in Transportrichtung hintereinander angeordnet sind, gezeigt. Gegenüberliegende Rampen haben den Abstand d. Es sei angemerkt, dass die Rampen auch zueinander und/oder zur Transportrichtung schräggestellt sein oder werden können. Die Rampen sind jeweils quer zur Transportrichtung verschiebbar angeordnet. Beim Führen der Querbalken mittels der Rampen liegt eine derartige Koppelung vor, dass die Querbalken und entsprechend die Halteelemente quer zur Transportrichtung verschoben werden, wenn die Rampe quer zur Transportrichtung verschoben wird. Indem eine oder beide Rampen eines Paars von ersten und zweiten Rampen quer zur Transportrichtung so verschoben werden, dass sich der Abstand der an den entsprechenden Querbalken befestigten Halteelemente ändert, wird die Breite der Beutelaufnahmen geändert. So können die Beutelaufnahmen an unterschiedliche Beutelformate angepasst werden oder das Öffnungsmaß der Beutel kann eingestellt werden. Vorzugsweise werden beide der gegenüberliegenden Rampen um den gleichen Weg in entgegengesetzte Richtung verstellt. So kommt es nicht zu einem Versatz der Transportstrecken quer zur Transportrichtung.In the figure, a plurality of first cross bars and second cross bars are shown. One or more first transverse beams are guided in operation along a plurality of successive ramps 8a, which are arranged parallel to the transport direction in this example. The second crossbars are guided in operation along opposite ramps 8b in synchronism with the first crossbars. In the figure, a plurality of pairs of first ramps and second ramps, which are arranged one behind the other in the transport direction, are shown. Opposite ramps have the distance d. It should be noted that the ramps can also be inclined to one another and / or to the direction of transport. The ramps are each arranged displaceably transversely to the transport direction. When guiding the crossbars by means of the ramps, such a coupling is present that the transverse bars and correspondingly the holding elements transversely be moved to the transport direction when the ramp is moved transversely to the transport direction. By displacing one or both ramps of a pair of first and second ramps transversely to the transport direction such that the distance of the holding elements attached to the respective crossbar changes, the width of the bag receivers is changed. Thus, the bag receivers can be adapted to different bag formats or the opening size of the bag can be adjusted. Preferably, both of the opposing ramps are displaced in the opposite direction by the same path. Thus, there is no offset of the transport paths transverse to the transport direction.

Die Verarbeitungsvorrichtung umfasst zwei Verstelleinrichtungen, die so ausgebildet sind, dass jeweils die Position verschiedener Rampen durch Verstellen der Verstelleinrichtung gleichzeitig und zugleich individuell bzw. unabhängig voneinander einstellbar ist.The processing device comprises two adjusting devices, which are designed such that the position of different ramps can be adjusted simultaneously by adjusting the adjusting device and at the same time individually or independently of one another.

Die Verstelleinrichtungen in diesem Beispiel umfassen jeweils mehrere Stellglieder 11 und eine Verstellstange 12, wobei die Stellglieder je eine Rampe und die Verstellstange koppeln. Die Verstellstange ist in diesem Beispiel an der den Querstangen bzw. den Beutelaufnahmen abgewandten Seite mehrerer hintereinander angeordneten Rampen angeordnet, kann jedoch auch an einer anderen Position angeordnet sein. Zudem ist die Verstellstange parallel zur Transportrichtung angeordnet, kann jedoch alternativ auch anders ausgerichtet sein, solange die geeigneten Übersetzungselemente verwendet werden. In diesem Beispiel sind sowohl den ersten als auch den zweiten Rampen Verstellstangen zugeordnet. Dies muss jedoch nicht der Fall sein, denn zum Verstellen der Breite der Beutelaufnahmen genügt es, wenn die Rampen auf einer Seite der Transportstrecke aufeinander zu oder voneinander weg bewegt, insbesondere quer zur Transportrichtung verschoben, werden. Die Verstellstange kann einstückig ausgebildet sein oder aus mehreren aneinander befestigten Stangen bestehen.The adjusting devices in this example each comprise a plurality of actuators 11 and an adjusting rod 12, wherein the actuators each couple a ramp and the adjusting rod. The adjusting rod is arranged in this example on the transverse rods or the bag receptacles facing away from a plurality of successively arranged ramps, but may also be arranged at a different position. In addition, the adjusting rod is arranged parallel to the transport direction, but may alternatively be oriented differently, as long as the appropriate translation elements are used. In this example, adjustment rods are associated with both the first and second ramps. However, this need not be the case, because to adjust the width of the bag receptacles, it is sufficient if the ramps on one side of the transport path to each other or moved away from each other, in particular transversely to the transport direction, are. The adjusting rod may be formed in one piece or consist of several rods attached to each other.

Die hintereinander angeordneten Rampen sind über die Stellglieder mit der Verstellstange gekoppelt. Die Stellglieder sind derart ausgebildet, dass eine Bewegung der Verstellstange parallel zur Transportrichtung in eine Bewegung der Rampe quer zur Transportrichtung übersetzt wird. Es sei angemerkt, dass eine Schrägstellung der Rampen erfolgen kann, wenn Stellglieder mit unterschiedlichen Übersetzungen entlang einer Rampe angreifen.The successively arranged ramps are coupled via the actuators with the adjusting rod. The actuators are designed such that a movement of the adjusting rod is translated parallel to the transport direction in a movement of the ramp transversely to the transport direction. It should be noted that an inclination of the ramps can occur when actuators with different translations attack along a ramp.

Wie weit die Rampen quer zur Transportrichtung bewegt (und/oder gegebenenfalls schräggestellt) werden, hängt von den verwendeten Stellgliedern ab. Wenn der Öffnungsgrad in Transportrichtung zunehmen soll, können für aufeinanderfolgende Rampen Stellglieder mit unterschiedlicher Übersetzung verwendet werden. So können die Positionen der Rampen durch ein Verstellen der Position der Verstellstange unabhängig voneinander, gemäß den jeweiligen Stellgliedern, eingestellt werden. Die Stellglieder können beispielsweise in Form von Kulissen ausgebildet sein.How far the ramps are moved transversely to the direction of transport (and / or possibly tilted) depends on the actuators used. If the opening degree in the direction of transport is to increase, actuators with different ratios can be used for successive ramps. Thus, the positions of the ramps can be adjusted independently of one another by adjusting the position of the adjusting rod according to their respective positions Actuators to be adjusted. The actuators may be formed, for example in the form of scenes.

Figur 1b zeigt einen geöffneten Folienbeutel, hier in Form eines Standbodenbeutels, bei dem oben eine Öffnung entsteht und unten ein Boden aufgefaltet wird, wenn er seitlich zusammengeschoben wird. Figur 1c zeigt eine Schrägansicht der ersten Ausführungsform. FIG. 1b shows an open foil bag, here in the form of a stand-up pouch, in which an opening is formed above and below a bottom is unfolded when it is pushed together laterally. Figure 1c shows an oblique view of the first embodiment.

Figur 2 zeigt eine Seitenansicht des in Figur 1c angedeuteten Bereichs, in dem eine Verstellstange 12, eine Rampe mit einem flächigen Endstück 16, ein Antrieb 17, ein Übersetzungsmechanismus 18 im Detail gezeigt sind. Eine Schrägansicht eines solchen Bereichs ist in Figur 3 gezeigt. Der Antrieb, der in diesem Beispiel ortsfest, beispielsweise an einem Gestell, angeordnet ist, treibt die Verstellstange an und bewegt sie parallel zur Transportrichtung. Über einen Übersetzungsmechanismus 18, beispielsweise ein Getriebe, wird die Bewegung des Antriebs zudem in eine Bewegung der Rampe übersetzt, so dass die Rampe quer zur Transportrichtung bewegt wird, wenn der Antrieb betätigt wird. Der Übersetzungsmechanismus setzt an dem flächigen Endstück 16 der Rampe an. Die Übertragung der Bewegung der Verstellstange erfolgt also in diesem Bereich nicht nur durch die Stellglieder sondern zusätzlich durch den Übersetzungsmechanismus 18. Dies bewirkt an dem Endstück der Rampe eine Stabilisierung. Diese Ausführung ist vorteilhaft, da so das Öffnungsmaß bis zur Stelle an der die Beutelausgabe stattfindet definiert ist, was am Scheitelpunkt der Umlenkung stattfindet. FIG. 2 shows a side view of the in Figure 1c indicated area in which an adjusting rod 12, a ramp with a flat end piece 16, a drive 17, a transmission mechanism 18 are shown in detail. An oblique view of such a region is in FIG. 3 shown. The drive, which is stationary in this example, for example, on a frame, drives the adjusting rod and moves it parallel to the transport direction. Via a transmission mechanism 18, for example a transmission, the movement of the drive is also translated into a movement of the ramp, so that the ramp is moved transversely to the transport direction when the drive is actuated. The translation mechanism starts at the flat end 16 of the ramp. The transmission of the movement of the adjusting rod thus takes place in this area not only by the actuators but in addition by the translation mechanism 18. This causes stabilization at the tail end of the ramp. This embodiment is advantageous because it defines the opening dimension up to the point at which the bag dispensing takes place, which takes place at the apex of the diversion.

Figur 4 zeigt eine Detailansicht zweier Rampen, einer Verstellstange und einiger Stellglieder, die in der obigen Ausführungsform verwendet werden können. Im Folgenden werden die Stellglieder im Detail beschrieben. Natürlich kann in der obigen Ausführungsform auch ein anderes Stellglied verwendet werden. FIG. 4 shows a detailed view of two ramps, an adjusting rod and some actuators that can be used in the above embodiment. In the following, the actuators will be described in detail. Of course, another actuator may be used in the above embodiment.

Wie hier zu erkennen ist, ist ein Element 13 mit einer länglichen Aussparung 13a positionsfest an der Verstellstange befestigt. Die Aussparung ist im Betrieb auf der Oberseite des Elements und bezogen auf die Transportrichtung schräg angeordnet. Mit anderen Worten weist sie eine bezogen auf die Transportrichtung geneigte Ausrichtung auf. Dabei kann sie beispielsweise um 1° bis 60°, insbesondere 5° bis 45° insbesondere, 10 bis 30° geneigt sein. Ein Verbindungselement 14 ist an einem ersten Ende positionsfest und drehbar an einer Rampe befestigt. Das andere (zweite) Ende ist in der Aussparung derart gelagert, in diesem Fall von oben eingehängt, dass es in der Aussparung verschoben werden kann. Dabei ist die Form der Aussparung und des zweiten Endes derart gewählt, dass eine Drehbewegung des zweiten Endes in der Aussparung gesperrt wird. Das Verbindungselement ist in einem ortsfest angeordneten Führungselement 15 gelagert, das eine Bewegung des Verbindungselements und somit auch der Rampe in vertikaler Richtung und parallel zur Transportrichtung sperrt. Die Verstellstange ist derart gelagert, dass eine vertikale Bewegung und eine Bewegung quer zur Transportrichtung gesperrt sind. Somit ist die Verstellstange nur parallel zur Transportrichtung bewegbar und die Rampe ist nur quer zur Transportrichtung bewegbar. Es sei angemerkt, dass die Rampe nicht nur verschiebbar sondern auch schrägstellbar sein kann, wie oben erläutert. Die Länge und Neigung der Aussparung definieren die Übersetzung des Stellglieds.As can be seen here, an element 13 with an elongated recess 13a fixed in position fixed to the adjusting rod. The recess is in operation on the top of the element and arranged obliquely relative to the transport direction. In other words, it has a direction inclined with respect to the transport direction. It may, for example, be tilted by 1 ° to 60 °, in particular 5 ° to 45 ° in particular, 10 to 30 °. A connecting element 14 is fixed in position at a first end and rotatably mounted on a ramp. The other (second) end is supported in the recess, in this case hooked from above, that it can be moved in the recess. The shape of the recess and the second end is selected such that a rotational movement of the second end is locked in the recess. The connecting element is mounted in a fixedly arranged guide element 15, which is a movement of the connecting element and thus also the ramp in vertical direction and parallel to the transport direction locks. The adjusting rod is mounted such that a vertical movement and a movement are locked transversely to the transport direction. Thus, the adjusting rod is movable only parallel to the transport direction and the ramp is movable only transversely to the transport direction. It should be noted that the ramp can be not only displaceable but also tiltable, as explained above. The length and inclination of the recess define the translation of the actuator.

Bei langen Rampen sind vorzugsweise mehrere solche Stellglieder vorgesehen, da sonst ein unkontrolliertes Kippen der Rampe zur Transportrichtung auftreten kann.For long ramps, several such actuators are preferably provided, since otherwise an uncontrolled tilting of the ramp can occur to the transport direction.

Es versteht sich, dass alternativ zu der oben beschriebenen Koppelung das Element 13 mit der länglichen Aussparung auch an der Rampe und das Verbindungselement an der Verstellstange befestigt werden können. Außerdem kann statt des Elements mit der Aussparung ein anderes Element zur Übersetzung der Bewegung verwendet werden.It is understood that as an alternative to the coupling described above, the element 13 with the elongated recess can also be attached to the ramp and the connecting element to the adjusting rod. In addition, instead of the element with the recess, another element can be used to translate the movement.

Die Funktionsweise einer Rampenverstellung mit einer oben beschriebenen Vorrichtung ist wie folgt: Wird die Verstellstange mittels des Antrieb entlang der Transportrichtung verschoben, so nimmt sie das Element 13 mit der länglichen Aussparung 13a mit. Da das Verbindungselement in der Aussparung gelagert ist, wird es zu einer Bewegung gezwungen. Aufgrund der zur Transportrichtung geneigten Ausrichtung der Aussparung und da das Verbindungselement in der Richtung parallel zur Transportrichtung nicht mit bewegt werden kann, da es durch das Führungselement in dieser Richtung gesperrt wird, wird es in diesem Beispiel quer zur Transportrichtung verschoben. Dabei wird es durch das Führungselement geführt. Durch die feste Verbindung mit der Rampe nimmt das Verbindungselement die Rampe mit.The operation of a ramp adjustment with a device described above is as follows: If the adjusting rod is displaced by the drive along the transport direction, so it takes the element 13 with the elongated recess 13 a with. Since the connecting element is mounted in the recess, it is forced to move. Due to the inclined direction of the transport direction alignment of the recess and since the connecting element in the direction parallel to the transport direction can not be moved, since it is locked by the guide member in this direction, it is moved in this example transverse to the transport direction. It is guided by the guide element. Due to the fixed connection with the ramp, the connecting element takes with the ramp.

Die oben beschriebene Ausführungsform ermöglicht, mit nur einem Antrieb und geeigneten Übersetzungselementen mehrere hintereinander angeordnete Rampen zusammen mit genau einem Antrieb aber dennoch unabhängig voneinander zu verstellen.The embodiment described above makes it possible, with only one drive and suitable translation elements, to adjust a plurality of successively arranged ramps together with exactly one drive but nevertheless independently of one another.

Es sei angemerkt, dass in Fällen, in denen eine Schrägstellung einer Rampe vorgesehen ist, vorzugsweise entlang der Rampe verschiedene Stellglieder angeordnet sind, von denen mindestens eines ortsfest und nicht rotierbar und andere ortsfest und rotierbar angeordnet und drehbar an der Rampe befestigt sind.It should be noted that in cases in which an inclination of a ramp is provided, preferably along the ramp, various actuators are arranged, of which at least one stationary and not rotatable and others are arranged stationary and rotatable and rotatably mounted on the ramp.

Figur 5 zeigt eine zweite Ausführungsform einer Verarbeitungsvorrichtung für Folienbeutel. Die Vorrichtung ist im Prinzip wie die Vorrichtung in Figur 1 ausgebildet. Hier sind jedoch den Rampen eigenen Stellantriebe 9 zugeordnet. In diesem Beispiel erfolgt das Verschieben jeder der Rampen jeweils mittels eines eigenen Stellantriebs entlang einer Stange 10 oder einer Schiene. FIG. 5 shows a second embodiment of a processing device for foil bag. The device is in principle like the device in FIG. 1 educated. Here, however, the ramp own actuators 9 are assigned. In this example, each of the ramps is displaced by means of its own actuator along a bar 10 or a rail.

Die Stellantriebe sind in diesem Beispiel mit einer gemeinsamen Steuereinrichtung 9a verbunden, die die Stellantriebe ansteuert.The actuators are connected in this example with a common control device 9a, which controls the actuators.

In den oben beschriebenen Ausführungsformen sind vorzugsweise ein oder mehrere Gestelle vorgesehen, die lediglich der Übersichtlichkeit halber nicht dargestellt sind. An diesem Gestell bzw. diesen Gestellen sind die Führungselemente 15 und/oder der Antrieb 17 befestigt und es bzw. sie dienen zur Lagerung der Rampen und der Verstellstangen.In the embodiments described above, one or more racks are preferably provided, which are not shown for the sake of clarity. At this frame or these racks, the guide elements 15 and / or the drive 17 are fixed and it or they are used to support the ramps and the adjusting rods.
