Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Vorrichtung zum Herauslösen von Teilbereich aus einem bahnartigen Folienmaterial. Das Folienmaterial kann ein Einschicht- oder Mehrschicht-Material sein und beispielsweise auf einem Rollenkörper aufgewickelt vorhanden sein. Von diesem Rollenkörper kann eine derartige Bahn abgezogen und in einem getakteten oder kontinuierlich ablaufenden Arbeitsverfahren bearbeitet wie beispielsweise verformt werden. Entsprechend dem jeweiligen Anwendungsfall kann es erforderlich werden, Teilbereiche aus dem bahnartigen Folienmaterial herauszulösen.The present invention relates to a device for Removing part of a sheet-like film material. The film material can be a single-layer or Be multilayer material and for example on one Roll body may be present coiled. From this reel body such a path can be drawn off and in one clocked or continuous work processes processed such as deformed. Corresponding depending on the application, it may be necessary Detach partial areas from the sheet-like film material.

STAND DER TECHNIKSTATE OF THE ART

Es ist bekannt, aus einem Folienmaterial Teilbereiche herauszustanzen. Je nach Art und Dicke des zu zertrennenden Folienmaterials sowie der Größe und Länge der Stanzlinie können sehr hohe Stanzkräfte erforderlich werden. Die entsprechenden Stanz-Vorrichtungen müssen dann entsprechend kräftig dimensioniert sein. Je schwerer die Stanzvorrichtungen werden, desto weniger geeignet sind sie, während des Stanzvorganges mit der sich in Transportrichtung bewegenden Folienbahn mitbewegt zu werden. Stanzvorrichtung eignen sich daher vorwiegend für stationäre Stanzvorgänge.It is known to use partial areas from a film material punch out. Depending on the type and thickness of the material to be cut Foil material as well as the size and length of the punching line very high punching forces may be required. The corresponding punching devices must then be used accordingly be well dimensioned. The heavier the punching devices the less suitable they are while the punching process with the in the transport direction moving film web to be moved. punching device are therefore primarily suitable for stationary punching processes.

GB-A-618008 offenbart eine Vorrichtung gemäß Oberbegriff des Anspruchs 1. GB-A-618008 discloses an apparatus according to Preamble of claim 1.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine wirtschaftlich günstige Möglichkeit zum Herauslösen von Teilbereichen aus einem bahnartigen Folienmaterial anzugeben, insbesondere auch bei sich bewegendem Folienmaterial.The invention is based on this prior art based on the task of being economically viable Possibility to separate partial areas from one specify sheet-like film material, in particular also in moving foil material.

Diese Erfindung ist durch die Merkmale des Anspruchs 1 gegeben. Weiterbildungen der Erfindung sind Gegenstand von Unteransprüchen.This invention is characterized by the features of claim 1 given. Developments of the invention are the subject of Dependent claims.

Die erfindungsgemäßen Vorrichtungen zeichnen sich dementsprechend dadurch aus, dass eine Schneidkante in einer Wälzbewegung durch die Folienmaterial-Bahn hindurchgedrückt wird. Dies hat den Vorteil, dass die erforderlichen Druckbeziehungsweise Zug-Kräfte zum Zerteilen des Folienmaterials relativ klein sind. Daher können entsprechende Vorrichtungen vergleichsweise schlank und damit leicht ausgebildet werden. Diese Vorrichtungen eignen sich daher gut, während des Trennvorganges beispielsweise mit der sich in Transportrichtung bewegenden Bahn mitbewegt zu werden.The devices according to the invention stand out accordingly from the fact that a cutting edge in a Rolling movement pressed through the film material web becomes. This has the advantage that the required pressure or Tensile forces for cutting the film material are relatively small. Therefore, appropriate devices comparatively slim and therefore easy to train. These devices are therefore well suited during the Separation process, for example, with the in the transport direction moving track to be moved.

Bei einer ersten Art von Vorrichtung, bei der die Schneidkante in einer Wälzbewegung durch die Folienmaterial-Bahn hindurchgedrückt wird, kann die Schneidkante der freie Randbereich einer Messerschneide sein. Ein Druckglied wird dann drückend gegen den Messerrücken dieser Messerschneide so angelegt, dass die Messerschneide mit ihrer Schneidkante nicht gleichzeitig sondern nach und nach durch die Bahn hindurchgedrückt wird. Um die gewünschte Wälzbewegung der Messerschneide zu erzeugen, wird das Druckglied längs des Messerrückens bewegt.In a first type of device in which the Cutting edge in a rolling motion through the film material web is pushed through, the cutting edge of the free Edge area of a knife edge. A pressure member becomes then pushing against the back of this knife edge so that the knife edge with its cutting edge not at the same time but gradually through the train is pushed through. To the desired rolling movement of the To produce knife edge, the pressure member along the Knife back moves.

Um während der Wälzbewegung der Schneidkante sicherzustellen, dass die Folienmaterial-Bahn nicht an der Schneidkante hängenbleibt, kann neben der Messerschneide ein elastisch zusammendrückbares Pufferteil angeordnet werden. Beim Hineinwälzen des jeweiligen Bereiches der Schneidkante drückt sich dieses Pufferteil zusammen und entspannt sich wieder beim Herausbewegen dieses Bereiches der Schneidkante aus der Folienmaterial-Bahn. Beim Entspannen wird die zertrennte Folienmaterial-Bahn von der Schneidkante beziehungsweise Messerschneide weg bewegt. Dadurch wird verhindert, dass sich der zertrennte Bereich der Folienmaterial-Bahn seitlich an der Messerschneide festsetzen kann.To during the rolling movement of the cutting edge ensure that the film material web is not on the The cutting edge can get stuck next to the knife edge be arranged elastically compressible buffer part. When rolling in the respective area of the cutting edge this buffer part compresses and relaxes again when moving out this area of the cutting edge from the film material web. When relaxing, the severed sheet of film material from the cutting edge or knife edge moved away. This will prevents the severed area of the film material web Attach to the side of the knife edge can.

Die Messerschneide kann zu einem in sich geschlossenen Ring geformt sein, um ein wünschenswert vollständiges Herauslösen des jeweiligen Teilbereiches aus der Folienmaterial-Bahn zu ermöglichen. Dieser Messer-schneide-Ring kann zur besseren Handhabung der Vorrichtung an einer Platte anhängend befestigt sein. Dadurch ist es möglich, von oben eine Walze über die Platte drückend entlangrollen zu lassen und dadurch den Messerschneide-Ring umfangsmäßig nacheinander durch die Folienmaterial-Bahn hindurch zu drücken. The knife edge can become a self-contained ring be shaped to provide a desirable complete detachment of the respective sub-area from the film material web enable. This knife-cutting ring can be used for better Handling the device attached to a plate be attached. This makes it possible to have a roller from above to let it roll over the plate and thereby circumferentially through the knife edge ring To push the film material web through.

Bei einer auch in der Zeichnung dargestellten Anwendungsvariante ist die Folienmaterial-Bahn der kragenartige Randbereich eines mit einem flüssigen oder pastenförmigen Füllstoff gefüllten Beutels. In diesem Randbereich ist eine untere Bahn, die zu einem topfartigen Behältnis verformt und mit dem Füllstoff gefüllt ist, mit einer oberen Bahn, die den Deckel dieses topfartigen Behältnisses bildet, füllstoffdicht verbunden. Mehrere derartiger Behältnisse sind gleichzeitig in der von einem Rollenkörper abgezogenen Folienmaterial-Bahn vorhanden. Mit der erfindungsgemäßen Vorrichtung können dann die in einem Bahnbereich vorhandenen mehreren topfartigen Behältnisse aus der Bahn herausgetrennt werden. Während des Trennvorganges wird die Vorrichtung mit der sich fortbewegenden Bahn mitbewegt.In an application variant also shown in the drawing the film material web is the collar-like edge area one with a liquid or pasty Filler filled bag. In this border area there is one lower track, which deforms into a pot-like container and is filled with the filler, with an upper sheet that forms the lid of this pot-like container, filler-tight connected. There are several such containers at the same time in the subtracted from a reel body Foil material web available. With the invention Devices can then be used in a railway area separated several pot-like containers from the web become. During the separation process, the device is connected moving with the moving train.

Bei diesem in der Zeichnung dargestellten Ausführungsbeispiel bestehen die beiden Bahnen, aus denen die Behältnisse hergestellt sind, aus wasserlöslichem Folienmaterial. In this embodiment shown in the drawing consist of the two tracks that make up the Containers are made from water soluble Film material.

Weitere Vorteile und Merkmale der Erfindung sind den in den Ansprüchen ferner angegebenen Merkmalen sowie den in der Zeichnung dargestellten Ausführungsbeispielen zu entnehmen. Further advantages and features of the invention are those in the Claims further specified features as well as in the Drawing shown embodiments can be seen.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS OF CARRYING OUT THE INVENTION

Eine in Fig. 1 ausschnittsweise dargestellte Trennstation 10 ist Teil einer Maschinenanlage, mittels der eine untere Folienbahn 12 und eine obere Folienbahn 14 so behandelt sind, dass die untere Bahn 12 zu topfartigen Behältnissen 16 verformt, mit Füllstoff 18 befüllt und mittels der oberen Bahn 14 verschlossen wurde. Die dadurch entstehende Folienmaterial-Bahn 20 besitzt also voneinander getrennte Bereiche, die topfartige Behältnisse 16 darstellen.A separation station 10 shown in detail in FIG. 1 is part of a machine system by means of which a lower Film web 12 and an upper film web 14 treated in this way are that the lower track 12 to pot-like containers 16 deformed, filled with filler 18 and by means of the upper Lane 14 was closed. The resulting Foil material web 20 thus has separate ones Areas that represent pot-like containers 16.

Die topfartigen Behältnisse 16 sind durch Randbereiche 22 voneinander getrennt. In diesen Randbereichen 22 sind die beiden Bahnen 12, 14 fest miteinander verbunden. Im vorliegenden Fall sind die beiden Bahnen, die wasserlöslich sind, in den Randbereichen 22 miteinander verschweißt. In diesen Randbereichen 22 wird die Folienmaterial-Bahn 20 zertrennt, so dass die topfartigen Behältnisse 16 dann einzeln vorhanden sind. Die im vorliegenden Fall zusammenhängenden Randbereiche 22 stellen ein Abfallprodukt dar.The pot-like containers 16 are defined by edge areas 22 separated from each other. In these edge areas 22 are the two tracks 12, 14 firmly connected. in the In the present case, the two lanes are water-soluble are welded to one another in the edge regions 22. In the film material web 20 becomes these edge regions 22 separated, so that the pot-like containers 16 then are individually present. The related in the present case Edge areas 22 represent a waste product.

Während des Transports der Folienmaterial-Bahn 20 durch die Trennstation 10 wird die Bahn 20 auf einer Transportplatte liegend 24 in Transportrichtung 26 bewegt. Die Transportrichtung 26 steht senkrecht auf der Zeichenebene der Figuren 1 bis 4. Während des Transportes der Transportplatte 24 in Transportrichtung 26 mit im vorliegenden Fall konstanter Geschwindigkeit, was bedeutet, dass auch die Trennstation 10 während des Trennvorganges mit dieser Transportgeschwindigkeit bewegt wird, wandert die Transportplatte 24 über einen maschinellen Unterbau 25. Die Transportplatte 24 besitzt der Anzahl der topfartigen Behältnisse 16 entsprechende Einwölbungen 28, die der Größe und Form der Behältnisse 16 entsprechen. Im Boden einer jeden Einwölbung 28 führt ein Stichkanal 30 zu einem Querkanal 32, der leitungsmäßig mit einem Längskanal 34 verbunden ist. Vom Längskanal 34 führt eine Leitung 36 zu einem Vakuumerzeuger 38. Mit Hilfe des Vakuumerzeugers 38 kann also ein Unterdruck in der Einwölbung 28 erzeugt werden. Bei in den Einwölbungen 28 einsitzender Folienmaterial-Bahn 20, was in Fig. 2 dargestellt ist, wird die Bahn 20 also in den Einwölbungen 28 und damit an der Transportplatte 24 lagefixiert.During the transport of the film material web 20 through the Separation station 10, the web 20 on a transport plate lying 24 moved in the transport direction 26. The direction of transport 26 is perpendicular to the drawing plane of the figures 1 to 4. During the transport of the transport plate 24 in Transport direction 26 with constant in the present case Speed, which means that the separation station 10 during the separation process at this transport speed is moved, the transport plate 24 moves via a mechanical substructure 25. The transport plate 24 has the number of pot-like Containers 16 corresponding vaults 28, the size and shape of the containers 16 correspond. In the bottom one each arch 28 leads to a branch channel 30 Cross channel 32, the line with a longitudinal channel 34th connected is.
