Dort wird ein Hüllmaterialstreifen durch Abzugswalzen von einer Vorratsrolle abgezogen und von zwei umlaufenden Saugbändern, die den Streifen gleichzeitig an seinen beiden Rändern mit Saugluft ergreifen, durch eine Querschneideinrichtung hindurch zwei weiteren Saugbandförderern zugeführt, die jedes mit einem der ersten Saugbänder fluchten und den Streifen ebenfalls an dessen Rändern mit Saugluft erfassen. Sobald ein Abschnitt des Materialstreifens von ausreichender Länge die Schneideinrichtung passiert hat, wird er von dem Streifen abgetrennt und um eine Packung gefaltet, indem diese quer gegen den Hüllmaterialabschnitt und mit diesem zusammen weiter in eine Falttasche eines Faltrevolvers geschoben wird. Bei dieser Vorrichtung hat sich gezeigt, daß beim Übergang von einem Förderer zum folgenden Falten in dem Hüllmaterialstreifen und Störungen des Folienlaufs nicht mit der notwendigen Sicherheit ausgeschlossen werden können. Dadurch können sich fehlerhafte oder unansehnliche Verpackungen ergeben.A device of the type specified at the beginning for conveying a strip of wrapping material in the form of a thin plastic film in a transfer or insertion station, in which a section of the wrapping material separated from the strip during insertion a pack of cigarettes in a pocket of a folding revolver around the pack is laid around, is described in DE 38 00 432 A1 (= US 4 999 967). There a wrapping material strip is pulled off a supply roll by take-off rollers and of two all-round suction belts that hold the strip at the same time Grip both edges with suction air, through a cross cutter fed two further suction belt conveyors, each with one of the first Suction tapes are aligned and the strip also at its edges with suction air capture. Once a section of the strip of material is of sufficient length the Has passed cutting device, it is separated from the strip and by one Pack folded by this against the wrapping material section and with this is pushed further together into a folding pocket of a folding turret. With this device it has been shown that when moving from a conveyor to the following folding in the wrapping material strip and disturbances in the film run cannot be excluded with the necessary security. Thereby defective or unsightly packaging can result.

Eine andere Vorrichtung zum Fördern eines Hüllmaterialstreifens in eine Einschubstation ist durch die EP 545 265 A2 bekannt. Diese Schritt zeigt einen ersten Förderer mit drei parallelen, umlaufenden Saugbändern, die zwischen zwei den Hüllmaterialstreifen seitlich einschneidenden Messern angeordnet sind.

Die Förderrichtung verläuft von unten nach oben, so daß jeder gerade vom Hüllmaterialstreifen abgetrennte Abschnitt frei an den Sauggreifern herabhängt. Dadurch fehlt im Bereich des zweiten Förderers, wo der Hüllmaterialabschnitt für das Herumfalten um eine Packung bereitgehalten wird, eine sichere Streifenführung.Another device for conveying a strip of wrapping material into an insertion station is known from EP 545 265 A2. This step shows a first sponsor with three parallel, all-round suction tapes, which between two the wrapping material strips laterally cutting knives are arranged. The suction tapes pass the beginning of the strip to two the front corners of the strip gripping suction grippers on the side next to the conveyor path of the wrapping material strip circumferential drive belts are attached and the strip on Pull the beginning of the strip into a push-in station. The conveying direction runs from below upwards, so that each section just separated from the wrapping material strip is free hanging on the suction pads. As a result, in the area of the second conveyor, where the wrapping material section is ready for folding around a package is a secure strip guide.

Der Erfindung liegt die Aufgabe zugrunde eine weitere Vorrichtung der eingangs beschriebenen Art anzugeben. Gelöst wird diese Aufgabe bei einer Vorrichtung der eingangs angegebenen Art erfindungsgemäß dadurch, daß das erste Fördermittel das Hüllmaterial etwa mittig erfassend und zum zweiten Fördermittel hin fördernd ausgebildet ist. Durch diese Ausbildung und Anordnung des ersten Fördermittels wird die Faltenbildung im Hüllmaterialstreifen im kritischen Übergabebereich zwischen dem ersten und dem zweiten Förderer unterbunden und es wird der Folienlauf in diesem Abschnitt der Folienzuführung erheblich verbessert.The invention has for its object another device of the beginning Specify the type described.

Die Vorrichtung nach der Erfindung bietet in besonderem Maße den Vorteil eines störungsfreien Folienlaufs im Übergabebereich zwischen zwei Förderern und einer weitestgehend falten- und knitterfreien Übergabe eines Hüllmaterialstreifens von einem vorangehenden Förderer auf einen folgenden. Dabei wirken sich die Maßnahmen nach der Erfindung besonders günstig auf die Zuführung dünner Folie, wie beispielsweise Polypropylenfolie oder Aluminiumfolie, zu einer Einschubstation in einer Packmaschine der tabakverarbeitenden Industrie aus. The device according to the invention offers the advantage of a particular degree trouble-free film run in the transfer area between two conveyors and one Largely wrinkle-free and crease-free transfer of a wrapping material strip from a previous sponsor to a following. The measures have an effect according to the invention particularly cheap on the supply of thin film, such as for example polypropylene film or aluminum film, to an insertion station in a packaging machine from the tobacco processing industry.

Die Erfindung wird nun anhand der Zeichnung näher erläutert.The invention will now be explained in more detail with reference to the drawing.

Die einzige Figur zeigt eine Ansicht eines Ausführungsbeispiels einer Vorrichtung nach der Erfindung in einer schematischen, perspektivischen Ansicht. The single figure shows a view of an embodiment of a device according to the invention in a schematic, perspective view.

Die Zeichnung zeigt als Ausführungsbeispiel der Vorrichtung nach der Erfindung eine Fördereinrichtung zum Zuführen eines Hüllmaterialstreifens 1 in eine Überführungsstation 2, in welcher ein Abschnitt 3 vom Hüllmaterial zum Zwecke des Einhüllens mit einer Packung 4 vereinigt wird.The drawing shows an embodiment of the device according to the invention a conveyor for feeding a wrapping material strip 1 into a transfer station 2, in which a section 3 of the wrapping material for the purpose of Envelope is combined with a pack 4.

Bei dem Hüllmaterial 1 handelt es sich im dargestellten Fall beispielsweise um eine dünnwandige Kunststoffolie aus Polypropylen, die als Aroma- und Klimaschutz außen um die ansonsten fertigen Zigarettenpackungen 4 herumgewickelt wird. Der Hüllmaterialstreifen wird durch eine Abzugseinrichtung, die im dargestellten Fall aus zwei Abzugswalzen 6a und 6b besteht, in Pfeilrichtung 7 von einer nicht dargestellten Vorratsrolle abgezogen und einer Fördervorrichtung übergeben, die aus einem ersten Fördermittel 8 und einem stromab anschließenden zweiten Fördermittel 9 besteht.In the case shown, the wrapping material 1 is, for example, one thin-walled plastic film made of polypropylene, used as aroma and climate protection is wrapped around the outside of the otherwise finished cigarette packs 4. Of the Wrapping material strips through a take-off device, which in the case shown consists of two take-off rollers 6a and 6b, in the direction of arrow 7 from one not shown Pulled off the supply roll and passed it to a conveyor, which made a first funding 8 and a downstream second funding 9 exists.

Als erstes Fördermittel 8 ist ein umlaufendes luftdurchlässiges Saugband 11 vorgesehen, dessen Fördertrum in der Förderebene des Hüllmaterialstreifens 1 etwa in der Mitte zwischen dessen Seitenrändern parallel zur Förderrichtung verläuft. Mit einer Unterdruckkammer 12 wird an das Fördertrum des Saugbandes 11 ein Saugzug angelegt, mit dem der Hüllmaterialstreifen 1 am Saugband 11 gehalten wird. Die Saugkammer ist mit einer nicht gezeigten Unterdruckquelle verbunden. Angetrieben wird das Saugband 11 über einen Zahnriemen 13 von einem Motor 14, der auch das Walzenpaar 6a, 6b antreibt, so daß die Fördergeschwindigkeit der Abzugswalzen gleich der des Saugbandes 11 ist.A circumferential air-permeable suction belt 11 is provided as the first conveying means 8, whose conveyor run in the conveyor plane of the wrapping material strip 1 approximately in the middle between its side edges runs parallel to the conveying direction. With a vacuum chamber 12 is a suction train on the conveyor strand of the suction belt 11 with which the wrapping material strip 1 is held on the suction belt 11. The suction chamber is connected to a vacuum source, not shown. Driven is the suction belt 11 via a toothed belt 13 by a motor 14, the also drives the pair of rollers 6a, 6b, so that the conveying speed of the Take-off rollers is equal to that of the suction belt 11.

Auf das Saugband 11 folgt stromab das zweite Fördermittel 9, das zwei Saugbänder 16 und 17 aufweist. Die Fördertrume der Saugbänder 16 und 17 erfassen den Hüllmaterialstreifen 1 mit Saugzug parallel an seinen Rändern und bewegen ihn in Förderrichtung in die Übenführungsstation 2. Der für die Erzeugung des Saugzuges erforderliche Unterdruck wird mittels Unterdruckkammern 18 und 19, die ebenfalls mit einer nicht dargestellten Unterdruckquelle verbunden sind, an die Saugbänder gelegt. Ein separater Motor 21 treibt die Saugbänder 16 und 17 unabhängig vom Saugband 11 an.Downstream of the suction belt 11 is the second conveyor 9, the two suction belts 16 and 17. Record the conveying dreams of the suction belts 16 and 17 the wrapping material strip 1 with suction parallel to its edges and move him in the conveying direction in the practice guide station 2. The for the generation of the Vacuum required vacuum is by means of vacuum chambers 18 and 19, which are also connected to a vacuum source, not shown, to which Suction tapes placed. A separate motor 21 drives the suction belts 16 and 17 independently from the suction belt 11.

Die Anordnung des Saugbandes 11 des ersten Fördermittels 8 in der Mitte zwischen den Seitenrändern des Hüllmaterialstreifens 1 bewirkt überraschenderweise eine falten- und knitterfreie Übergabe der Hüllmaterialfolie an die Bänder 16 und 17 des zweiten Fördermittels 9 und verhindert Störungen des Laufs des Hüllmaterialstreifens in diesem Übergangsbereich zwischen dem ersten und dem zweiten Fördermittel. Damit werden die Nachteile der Falten- und Knitterbildung der bekannten Fördereinrichtung mit einem ersten Fördermittel mit zwei den Hüllmaterialstreifen an beiden Rändern ergreifenden Saugbändern vermieden. Zur Erklärung der Verbesserung des Laufs des Hüllmaterialstreifens in diesem Übergabebereich wird angenommen, daß bei der bekannten Vorrichtung Fluchtungsfehler der aufeinanderfolgenden Saugbänder und Schlupfdifferenzen zu den Laufstörungen des Materialstreifens führen. Die erfindungsgemäß vorgeschlagene Ausbildung des ersten Fördermittels 8 als versetzt in der Mitte zwischen den Rändern des Hüllmaterialstreifens verlaufendes Saugband hilft diesen Nachteilen wirksam ab.The arrangement of the suction belt 11 of the first conveyor 8 in the middle between the side edges of the wrapping material strip 1 surprisingly causes a wrinkle-free and wrinkle-free transfer of the wrapping material film to the belts 16 and 17 of the second conveying means 9 and prevents disturbances in the running of the wrapping material strip in this transition area between the first and the second funding. The disadvantages of the formation of folds and creases are thus known Conveyor device with a first conveyor with two the wrapping material strips Avoiding suction tapes on both edges avoided. To explain the improvement the run of the wrapping material strip in this transfer area assumed that in the known device misalignment of the successive Suction tapes and slip differences to the running disturbances of the material strip to lead. The inventive design of the first Conveyor 8 as offset in the middle between the edges of the wrapping material strip running suction belt effectively remedies these disadvantages.

Dem Übergabebereich zwischen dem ersten Fördermittel 8 und dem zweiten Fördermittel 9 ist eine Schneideinrichtung 22 mit einem Querschneider 23 und einem feststehenden Gegenmesser 24 zugeordnet, die vom Hüllmaterialstreifen 1 Zuschnitte 3 vorgegebener Länge abtrennen.The transfer area between the first funding 8 and the second funding 9 is a cutting device 22 with a cross cutter 23 and a fixed counter knife 24 assigned by the wrapping material strip 1 Cut off blanks 3 of the specified length.

Zum Aufreißen der Hüllfolie vor dem Öffnen einer Packung 4 sind üblicherweise sogenannte Aufreißbändchen vorgesehen. Ein Einschnitt im Hüllmaterial markiert dabei den Anfang des Aufreißbändchens. Zum Einbringen eines solchen Einschnittes sind entsprechende Schneidmittel 26 vorgesehen, die beispielsweise aus einer Schneidwalze 27 und einer Gegenrolle 28 bestehen. Die Schneidwalze 27 ist am Umfang mit einem nicht dargestellten U-profilierten Messer versehen, das in den Hüllmaterialstreifen einen U-förmigen Einschnitt einbringt. Die Schneidwalze 27 und der Querschneider 23 sind von einem gemeinsamen Motor 29 angetrieben.To open the wrapping film before opening a package 4 are usually so-called tear tapes provided. An incision in the wrapping material is marked the beginning of the tear tape. For making such an incision Corresponding cutting means 26 are provided, which for example consist of a cutting roller 27 and a counter roller 28 exist. The cutting roller 27 is provided on the circumference with a U-shaped knife, not shown, which in creates a U-shaped incision in the wrapping material strip.

Entlang dieser Packungsbahn werden mit einem hin und her bewegbaren Schieber 32 die Packungen 4 nacheinander in Pfeilrichtung 33 gegen den Hüllmaterialabschnitt 3 und weiter durch ein als Rechteck angedeutetes Mundstück 34 hindurch in eine Falttasche eines nicht gezeigten Faltrevolvers eingeschoben, wobei der Hüllmaterialabschnitt 3 mitgenommen und U-förmig um die Packung 4 herumgelegt wird. In der Falttasche des Faltrevolvers werden dann die weiteren erforderlichen Faltvorgänge ausgeführt. Weitere Einzelheiten der hier beschriebenen Vorrichtung und dieser Faltvorgänge, die nicht Gegenstand der vorliegenden Erfindung sind, sind der DE 38 00 432 A1 (= US-PS 4 999 967) zu entnehmen, auf die hier ausdrücklich Bezug genommen wird.In the transfer station 2 one in the drawing crosses with dash-dotted lines Lines indicated packing line 31 the conveying path of the wrapping material strip 1. Be moved back and forth along this packing line with a Slide 32 the packs 4 one after the other in the direction of arrow 33 against the wrapping material section 3 and further by a mouthpiece 34 indicated as a rectangle inserted into a folding pocket of a folding turret, not shown, the wrapping material section 3 being carried along and being U-shaped around the pack 4 is put around.
