Description

Die Erfindung betrifft eine Vorrichtung und ein Verfahren zum Beleimen einer in einer Förderrichtung kontinuierlich bewegten Hüllmaterialbahn in einer Maschine der Tabak verarbeitenden Industrie, umfassend mindestens eine Leimdüse zum Auftragen von Leim auf die Hüllmaterialbahn.The invention relates to a device and a method for gluing a continuously moving in a conveying direction Hüllmaterialbahn in a machine of the tobacco processing industry, comprising at least one glue nozzle for applying glue to the Hüllmaterialbahn.

Eine derartige Beleimungseinrichtung ist beispielsweise aus der DE 10 2006 038 973 A1 bekannt.Such a gluing device is for example from the DE 10 2006 038 973 A1 known.

Bei einer Maschine der Tabak verarbeitenden Industrie können am Ort einer Beleimungsvorrichtung unerwünschte oder kontrollierte Abweichungen in der seitlichen Lage der Hüllmaterialbahn auftreten. Beispielsweise ist es bekannt, die seitliche Lage zweier Hüllmaterialbahnen in einer Doppelstrangmaschine mittels einer Spreizeinheit kontrolliert zu verstellen, um im Bereich der Zusammenführung der Hüllmaterialbahnen mit den Tabaksträngen eine Sollpositionierung der Hüllmaterialbahnen zu erreichen. Aufgrund der damit verbundenen seitlichen Lageänderung der Hüllmaterialbahnen verschiebt sich die Lage der Leimnähte auf den Hüllmaterialbahnen, was im ungünstigen Fall zu einer Beeinträchtigung der Leimverbindung und bei einem räumlich getrennten Leimauftrag beispielsweise zu einer Überlappung von Kalt- und Heißleimnaht führen kann.In a machine of the tobacco-processing industry, unwanted or controlled deviations in the lateral position of the wrapping material web may occur at the location of a gluing device. For example, it is known to adjust the lateral position of two wrapping material webs in a double-stranding machine in a controlled manner by means of a spreader unit in order to achieve a desired positioning of the wrapping material webs in the area of the merging of the wrapping material webs with the tobacco strands. Due to the associated lateral change in position of the Hüllmaterialbahnen the position of the glue lines on the Hüllmaterialbahnen shifts, which can lead to an adverse effect on the glue connection and a spatially separated glue application, for example, to an overlap of cold and hot glue.

Die Aufgabe der Erfindung besteht darin, eine Beleimungsvorrichtung und ein Beleimungsverfahren bereitzustellen, bei denen ein positionsgenauer Leimauftrag auf die Hüllmaterialbahn sichergestellt ist.The object of the invention is to provide a gluing device and a gluing method in which a positionally accurate glue application is ensured on the Hüllmaterialbahn.

Die Erfindung löst diese Aufgabe mit den Merkmalen der unabhängigen Ansprüche. Mittels der gesteuerten Verstelleinrichtung kann die Leimdüse jederzeit in einer zu der Hüllmaterialbahn seitlichen Richtung so verstellt bzw. nachgestellt werden, dass die Leimnaht trotz einer seitlichen Lageabweichung der Hüllmaterialbahn jederzeit an der gleichen seitlichen Position auf die Hüllmaterialbahn aufgetragen wird, so dass eine Beeinträchtigung der Leimverbindung zuverlässig vermieden werden kann.The invention solves this problem with the features of the independent claims. By means of the controlled adjusting device, the glue nozzle can be adjusted or adjusted at any time in a lateral direction to the wrapping material that the glue seam is applied at any time at the same lateral position on the Hüllmaterialbahn despite a lateral positional deviation of the Hüllmaterialbahn, so that an impairment of the glue connection reliable can be avoided.

Die Verstelleinrichtung kann vorteilhaft mittels einer in einer zu der Hüllmaterialbahn seitlichen Richtung angeordneten Linearführung für die Leimdüse realisiert werden.The adjusting device can advantageously be realized by means of a linear guide for the glue nozzle arranged in a direction lateral to the wrapping material web.

In Maschinen mit einer Mehrzahl von Leimdüsen für eine Mehrzahl von Hüllmaterialbahnen, beispielsweise in Doppelstrangmaschinen, kann es vorteilhaft sein, wenn für jede Leimdüse eine unabhängig steuerbare Verstelleinrichtung vorgesehen ist. Damit sind unterschiedliche Lageabweichungen der einzelnen Hüllmaterialbahnen individuell kompensierbar.In machines with a plurality of glue nozzles for a plurality of wrapping material webs, for example in double-strand machines, it can be advantageous if an independently controllable adjusting device is provided for each glue nozzle. This allows different positional deviations of the individual Hüllmaterialbahnen be individually compensated.

Wenn eine seitliche Verstellung der Hüllmaterialbahn mittels einer Verstelleinheit vorgesehen ist, kann die Verstelleinrichtung vorzugsweise in Abhängigkeit von der Verstellung der Hüllmaterialbahn gesteuert sein. Die Beleimungsrichtung ist zweckmäßigerweise in der Förderrichtung hinter der Verstelleinheit für die Hüllmaterialbahn angeordnet, um deren Einfluss kompensieren zu können. Dabei kann die Verstelleinrichtung vorzugsweise separat von der Verstelleinheit betätigbar bzw. angetrieben sein. Alternativ kann die Verstelleinrichtung mit der Verstelleinheit für die Hüllmaterialbahn mechanisch gekoppelt sein. In diesem Fall ist ein gemeinsamer Antrieb ausreichend und eine Abstimmung zwischen separaten Antrieben für die Verstelleinrichtung und die Verstelleinheit ist entbehrlich.If a lateral adjustment of the wrapping material web is provided by means of an adjusting unit, the adjusting device can preferably be controlled as a function of the adjustment of the wrapping material web. The gluing direction is expediently arranged in the conveying direction behind the adjustment unit for the wrapping material web in order to be able to compensate for its influence. In this case, the adjusting device can preferably be actuated or driven separately from the adjusting unit. Alternatively, the adjustment with be mechanically coupled to the adjusting unit for the Hüllmaterialbahn. In this case, a common drive is sufficient and a vote between separate drives for the adjustment and the adjustment is unnecessary.

Vorzugsweise ist die Verstelleinrichtung in Abhängigkeit eines von einer Messeinrichtung zur Messung eines räumlichen Parameters der Hüllmaterialbahn ausgegebenen Meßsignals gesteuert. Der räumliche Parameter kann beispielsweise die seitliche Lage einer Hüllmaterialbahn, insbesondere im Bereich der Zusammenführung von Hüllmaterialbahn und Produktstrang, eine seitliche Lageabweichung, aber beispielsweise auch die Breite einer Teilbahn bei einer Mehrzahl von Hüllmaterialbahnen sein. Die Steuerung der Verstelleinrichtung kann in direkter Abhängigkeit von dem Meßsignal erfolgen. Alternativ kann es sich vorzugsweise um eine indirekte Abhängigkeit handeln, wenn eine Verstelleinheit für die Hüllmaterialbahn in Abhängigkeit von dem Meßsignal verstellt und die Verstelleinrichtung für die Leimdüse entsprechend nachgestellt wird.The adjusting device is preferably controlled as a function of a measuring signal output by a measuring device for measuring a spatial parameter of the wrapping material web. The spatial parameter can be, for example, the lateral position of a wrapping material web, in particular in the region of the combination of wrapping material web and product strand, a lateral positional deviation, but also, for example, the width of a part of web with a plurality of wrapping material webs. The control of the adjustment can be done in direct dependence on the measurement signal. Alternatively, it can preferably be an indirect dependency if an adjusting unit for the wrapping material web is adjusted as a function of the measuring signal and the adjusting device for the glue nozzle is readjusted accordingly.

Die Erfindung ist generell anwendbar auf sämtliche in der industriellen Produktion von stabförmigen Tabakartikeln, insbesondere Zigaretten, verwendeten Hüllmaterialbahnen. Eine bevorzugte Anwendung betrifft die Beleimung von Hüllmaterialbahnen in Strangmaschinen, insbesondere Papierbahnen zur Umhüllung von Tabakstöcken oder Filtern. Eine weitere denkbare Anwendung betrifft die Beleimung von Belagpapier in einer Filteransetzmaschine.The invention is generally applicable to all wrapping material webs used in the industrial production of rod-shaped tobacco articles, in particular cigarettes. A preferred application relates to the gluing of Hüllmaterialbahnen in extruding machines, especially paper webs for wrapping tobacco rods or filters. Another conceivable application relates to the gluing of tipping paper in a filter tipping machine.

Die erfindungsgemäße seitliche Verstellung der Leimdüsen erfolgt fortlaufend im Betrieb der Maschine. Die Erfindung ist damit abgrenzbar gegenüber nur in Stillstandszeiten der Maschine betätigbare Einrichtungen für Lagejustierungen der Leimdüsen, die beispielsweise bei einem Formatwechsel regelmäßig erforderlich sind. Mit derartigen Justiereinrichtungen kann der Erfolg der Erfindung nicht erzielt werden.The lateral adjustment of the glue nozzles according to the invention takes place continuously during operation of the machine. The invention is thus delimitable against only operable in downtime of the machine facilities for positional adjustments Glue nozzles, which are regularly required, for example, during a format change. With such adjusting the success of the invention can not be achieved.

Die Tabakstrangmaschine 10 zeigt in dem Ausschnitt gemäß den Figuren 1a, 1b zwei Papierbahnen 11a, 11b, die in einer mittels Pfeilen angedeuteten Förderrichtung durch die als Doppelstrangmaschine ausgebildete Tabakstrangmaschine 10 gefördert werden. Die Papierbahnen 11a, 11b durchlaufen in der Förderrichtung eine insbesondere als Spreizeinheit ausgebildete Papierverstelleinheit 12 zur Lageverstellung der Papierbahnen 11a, 11b mittels einer nicht näher gezeigten Walzenanordnung und eine Kaltbeleimungsvorrichtung 14 mit zwei Düsen 15a, 15b zur Erzeugung von Unterstützungs-Leimnähten auf den Papierbahnen 11a, 11b. Die Papierbahnen 11a, 11b werden dann nach einer Umlenkrollenanordnung 27 mit den Tabaksträngen 18a, 18b zur Umhüllung derselben zusammengeführt. Die Maschine 10 kann eine weitere Beleimungsvorrichtung 16 umfassen. In der Ausführungsform gemäß Fig. 1a ist beispielsweise eine Heißbeleimungsvorrichtung 16 mit Heißbeleimungsdüsen 17a, 17b zur Erzeugung entsprechender Heißleimnähte auf den Papierbahnen 11a, 11b in Förderrichtung hinter der Umlenkrollenanordnung 27 angeordnet. Im Ausführungsbeispiel gemäß Figur 1b ist eine weitere Beleimungsvorrichtung 16 mit Leimdüsen 17a, 17b zwischen der Kaltbeleimungsvorrichtung 14 und der Umlenkrollenanordnung 27 vorgesehen.The tobacco rod machine 10 shows in the cutout according to the FIGS. 1a . 1b two paper webs 11a, 11b, which are conveyed in a direction indicated by arrows conveying direction through the trained as a double-strand machine tobacco rod machine 10 become. The paper webs 11a, 11b pass through in the conveying direction a Papierverstelleinheit 12 in particular designed as a spreading unit for positional adjustment of the paper webs 11a, 11b by means of a roller assembly not shown in detail and a Kaltbeleimungsvorrichtung 14 with two nozzles 15a, 15b for generating support glue seams on the paper webs 11a, 11b. The paper webs 11a, 11b are then brought together after a deflection roller assembly 27 with the tobacco strands 18a, 18b for wrapping the same. The machine 10 may include another glueing device 16. In the embodiment according to Fig. 1a For example, a Heißbeleimungsvorrichtung 16 with Heißbeleimungsdüsen 17a, 17b for generating corresponding hot glue seams on the paper webs 11a, 11b arranged downstream of the Umlenkrollenanordnung 27 in the conveying direction. In the embodiment according to FIG. 1b a further gluing device 16 with glue nozzles 17a, 17b is provided between the cold gluing device 14 and the deflecting roller arrangement 27.

Im Bereich der Zusammenführung der Papierbahnen 11a, 11b mit den Tabaksträngen 18a, 18b sind Sensoren 19a, 19b zur Bestimmung insbesondere der seitlichen Lage der Papierbahnen 11a, 11b angeordnet. Seitlich bedeutet dabei in einer Richtung, die quer bzw. senkrecht zu der Förderrichtung und parallel zu der Hüll- bzw. Papierbahnebene verläuft. Die Sensoren 19a, 19b sind mit einer elektronischen Steuereinrichtung 20 verbunden, die beispielsweise in einer SPS-Steuerung der Maschine 10 realisiert sein kann. Die Steuereinrichtung 20 ist mit der Papierverstelleinheit 12 verbunden, was in den Figuren 1a, 1b nur schematisch gezeigt ist. Anhand der Meßsignale von den Sensoren 19a, 19b steuert bzw. regelt die Steuereinrichtung 20 die Stellorgane 13a, 13b der Papierverstelleinheit 12 im Betrieb der Maschine 10 individuell so an, dass die Papierbahnen 11a, 11b im Bereich der Zusammenführung mit den Tabaksträngen 18a, 18b jederzeit ihre Solllage einnehmen.In the area of merging the paper webs 11a, 11b with the tobacco strands 18a, 18b, sensors 19a, 19b are arranged for determining, in particular, the lateral position of the paper webs 11a, 11b. In this case, lateral means in a direction which runs transversely or perpendicular to the conveying direction and parallel to the envelope or paper web plane. The sensors 19a, 19b are connected to an electronic control device 20, which may be realized, for example, in a PLC control of the machine 10. The controller 20 is connected to the Papierverstelleinheit 12, which in the FIGS. 1a . 1b only shown schematically. Based on the measurement signals from the sensors 19a, 19b, the control device 20 controls or regulates the actuators 13a, 13b of the Papierverstelleinheit 12 individually in the operation of the machine 10 so that the paper webs 11a, 11b in the region of the merger with the tobacco strands 18a, 18b always assume their desired position.

Die Lageverstellung der Papierbahnen 11a, 11b durch die Papierverstelleinheit 12 würde ohne weitere Maßnahmen dazu führen, dass die durch die Beleimungsvorrichtung 14 aufgetragene Kaltleimnaht entsprechende Schwankungen ihrer seitlichen Lage auf den Papierbahnen 11a, 11b aufweisen würde. Gleiches gilt im Ausführungsbeispiel der Figur 1b für die durch die Beleimungsvorrichtung 16 aufgetragene Beleimung. In dem Ausführungsbeispiel gemäß Figur 1a könnte die Schwankung der Kaltleimnaht dazu führen, dass die Kaltleimnaht und die Heißleimnaht unerwünscht überlappen.The positional adjustment of the paper webs 11a, 11b by the Papierverstelleinheit 12 would lead without further action to the fact that applied by the gluing device 14 cold glue seam corresponding fluctuations of their lateral position on the paper webs 11a, 11b would have. The same applies in the embodiment of FIG. 1b for the gluing applied by gluing device 16. In the embodiment according to FIG. 1a The variation of the cold glue seam could cause the cold glue seam and the hot glue seam to overlap undesirably.

Um dem entgegenzuwirken, ist eine Verstelleinrichtung zum kontinuierlichen Verstellen insbesondere der Kaltleimdüsen 15a, 15b in seitlicher Richtung während des Betriebs der Maschine 10 vorgesehen. Dies wird im Folgenden anhand der Figuren 2 bis 6 für die Kaltbeleimungsvorrichtung 14 erläutert. In der Ausführungsform gemäß Figur 1b weist die Beleimungseinrichtung 16 vorzugsweise eine entsprechende Verstelleinrichtung auf. Im Übrigen ist die Erfindung selbstverständlich auch auf einzelne Kalt- und/oder Heißbeleimungsvorrichtungen anwendbar.To counteract this, an adjusting device for continuously adjusting in particular the cold glue nozzles 15a, 15b in the lateral direction during operation of the machine 10 is provided. This will be explained below on the basis of FIGS. 2 to 6 for the Kaltbeleimungsvorrichtung 14 explained. In the embodiment according to FIG. 1b the gluing device 16 preferably has a corresponding adjusting device. Incidentally, the invention is of course also applicable to individual cold and / or Heißbeleimungsvorrichtungen.

Die Leimdüsen 15a, 15b sind jeweils auf einem Träger 22a, 22b montiert. Die Träger 22a, 22b sind mittels Linearführungen 23 seitlich zu den Papierbahnen 11a, 11b unabhängig voneinander verschiebbar geführt. Die Verschieberichtung ist in den Figuren 2, 3 und 6 mittels Doppelpfeilen verdeutlicht. Zur unabhängigen Verschiebung der Träger 22a, 22b und damit der Leimdüsen 15a, 15b sind entsprechende Aktuatoren, hier elektrische Antriebe 25a, 25b und davon angetriebene Drehspindeln 24a, 24b, vorgesehen. Die Verwendung anderer elektrischer oder pneumatischer Aktuatoren ist möglich. Die Verschiebung wird durch die Steuereinrichtung 20 gesteuert, die eine geeignete Steuerverbindung zu den Aktuatoren 25a, 25b aufweist. Die Verschiebung wird dabei zweckmäßigerweise so gesteuert, dass die Leimdüsen 15a, 15b bei einer Verstellung der Papierbahnen 11a, 11b durch die Papierverstelleinheit 12 nachgeführt werden, so dass die seitliche Lage der Leimnähte auf den Papierbahnen 11a, 11b unabhängig von einer seitlichen Verschiebung der Papierbahnen durch die Papierverstelleinheit 12 konstant gehalten wird.The glue nozzles 15a, 15b are each mounted on a support 22a, 22b. The carriers 22a, 22b are guided by means of linear guides 23 laterally to the paper webs 11a, 11b displaced independently. The direction of displacement is in the Figures 2 . 3 and 6 illustrated by double arrows. For independent displacement of the carriers 22a, 22b and thus of the glue nozzles 15a, 15b are corresponding actuators, in this case electric drives 25a, 25b and rotary spindles 24a driven therefrom, 24b, provided. The use of other electric or pneumatic actuators is possible. The displacement is controlled by the controller 20, which has a suitable control connection to the actuators 25a, 25b. The displacement is expediently controlled so that the glue nozzles 15a, 15b are tracked by the Papierverstelleinheit 12 during an adjustment of the paper webs 11a, 11b, so that the lateral position of the glue seams on the paper webs 11a, 11b regardless of a lateral displacement of the paper webs through the Papierverstelleinheit 12 is kept constant.

Zum Reinigen der Leimdüsen 15a, 15b können diese im Stillstand der Maschine mittels eines linearen Verschiebemittels 26 in einer Richtung senkrecht zu der Hüllmaterial- bzw. Papierbahnebene vom Papier weg und wieder zurück verschoben werden.To clean the glue nozzles 15a, 15b, they can be moved away from the paper and back again by means of a linear displacement means 26 in a direction perpendicular to the wrapping material or paper web plane when the machine is at a standstill.
