Description

Die Erfindung betrifft eine Maschine der tabakverarbeitenden Industrie mit einer Papierzufuhreinheit zum Zufuhren von Papier zu einer Verarbeitungseinheit, die zum Umhüllen eines stabförmigen Produkts mit dem Papier vorgesehen ist, wobei die Maschine eine Beleimungseinheit zum Beleimen des Papiers an einer Beleimungsposition des Papierlaufs aufweist, sowie ein entsprechendes Papierbeleimungsverfahren.The invention relates to a machine in the tobacco processing industry with a paper feed unit for feeding paper to a processing unit for wrapping a rod-shaped product is provided with the paper, the machine a gluing unit for gluing the paper at a gluing position of the Has paper run, as well as a corresponding paper gluing process.

Aus der DE 198 06 673 A1 ist die Verwendung eines Belagpapiers bekannt, das eine bereits beim Papierhersteller aufgetragene Klebstoffschicht aufweist. In der Filteransetzmaschine wird die Klebstoffschicht durch Zuführung von Wasser aktiviert. Dies wird dadurch bewirkt, daß das übliche Beleimungswerk des Filteransetzers lediglich Wasser enthält.From DE 198 06 673 A1 the use of a covering paper is known, the one already has an adhesive layer applied by the paper manufacturer. In the filter attachment machine the adhesive layer is activated by adding water. This is caused by the fact that the usual gluing unit of the filter piecer only Contains water.

Aus der EP 1 269 870 A1 geht ein Filteransetzer hervor, bei dem ein Heizelement hinter dem Beleimungswerk angeordnet ist. Mit dem Heizelement wird das beleimte Belagpapier auf einen Feuchtegehalt von 4 % oder weniger getrocknet. Der Feuchtegehalt des Papiers kann vor und hinter dem Heizelement mittels entsprechender Feuchtesensoren gemessen und die Heizleistung des Heizelements in Abhängigkeit der Ausgangssignale der Feuchtesensoren geregelt werden.EP 1 269 870 A1 shows a filter attachment in which a heating element is behind the gluing unit is arranged. With the heating element the glued covering paper dried to a moisture content of 4% or less. The moisture content of the Paper can be placed in front of and behind the heating element using appropriate moisture sensors measured and the heating power of the heating element depending on the output signals the humidity sensors are regulated.

Wenn die Klebkraft des beleimten Papiers nicht optimal ist, kann dies zu Problemen insbesondere in der Verarbeitungseinheit führen. Dies gilt beispielsweise, wenn die Klebkraft nicht ausreicht, um eine hinreichende Verklebung des Papiers zu bewirken. Derartige Probleme können zu unerwünschten Ausfallzeiten führen.If the adhesive strength of the glued paper is not optimal, this can lead to problems lead in particular in the processing unit. This applies, for example, if the Adhesive power is not sufficient to ensure that the paper is adequately bonded. Such problems can lead to unwanted downtime.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Maschine bereitzustellen, bei der Probleme aufgrund nicht optimaler Klebkraft des beleimten Papiers reduziert sind. The object of the present invention is to provide a machine in the case of problems due to non-optimal adhesive strength of the glued paper reduced are.

Die Klebkraft des beleimten Papiers in der Verarbeitungseinheit hängt empfindlich von der Feuchte des Papiers ab. Die Feuchte des Papiers kann einerseits je nach Papierqualität, Transport- oder Lagerbedingungen oder weiterer Umstände schwanken, wobei derartige Schwankungen auch nur sporadisch auftreten können. Andererseits liegt die übliche Feuchte des vom Papierhersteller gelieferten Papiers häufig unterhalb eines optimalen Feuchtebereichs. Durch die erfindungsgemäße Befeuchtung des Papiers kann daher die Klebkraft des Papiers in der nachfolgenden Verarbeitungseinheit verbessert werden, so daß Probleme und Ausfallzeiten aufgrund nicht optimaler Klebkraft des beleimten Papiers reduziert werden können. Entscheidend für den Erfolg der Erfindung ist dabei die Anordnung der Befeuchtungseinrichtung vor der Beleimungsposition. Die Anordnung eines Teils der Papierzufuhreinrichtung "vor" oder "nach" einem anderen Teil der Papierzufuhreinrichtung bedeutet im Rahmen dieser Anmeldung eine entsprechende Anordnung bezogen auf die Zufuhrrichtung des Papiers. Entsprechendes gilt für eine Anordnung eines Teils der Papierzufuhreinrichtung "zwischen" zwei anderen Teilen der Papierzufuhreinrichtung.The adhesive strength of the glued paper in the processing unit depends on the moisture of the paper. The moisture content of the paper can vary depending on the paper quality, Transport or storage conditions or other circumstances fluctuate, such Fluctuations can only occur sporadically. On the other hand, the usual one Moisture of the paper supplied by the paper manufacturer is often below an optimum Humidity range. By moistening the paper according to the invention can therefore the adhesive strength of the paper is improved in the subsequent processing unit, so that problems and downtimes due to non-optimal adhesive strength of the glued Paper can be reduced. It is crucial for the success of the invention the arrangement of the moistening device before the gluing position. The order part of the paper feed device "before" or "after" another part of the Paper feed means in the context of this application a corresponding Arrangement based on the paper feed direction. The same applies to one Arrangement of a part of the paper feed device "between" two other parts of the Paper feeder.

Die Erfindung ist insbesondere anwendbar auf Belagpapier zum Verbinden von Filtern und Tabakstöcken in einem Filteransetzer einer Zigarettenproduktionsmaschine; auf Zigarettenpapier zum Umhüllen von Tabaksträngen in einer Strangeinheit einer Strangmaschine; sowie auf Filterumhüllungspapier für Zigarettenfilter in einer Filterherstellungsmaschine.The invention is particularly applicable to covering paper for connecting filters and tobacco sticks in a filter applicator of a cigarette production machine; on Cigarette paper for wrapping tobacco rods in one unit Rod machine; and on filter wrapping paper for cigarette filters in a filter manufacturing machine.

A control or regulation preferably takes place the amount of humidification depending on one or more humidity sensors output signal by means of a corresponding control device.

Zu diesem Zweck weist die Papierzufuhreinheit zweckmäßigerweise einen vor der Befeuchtungseinrichtung angeordneten ersten Feuchtesensor zur Messung der Papierfeuchte auf, wobei die Befeuchtungsmenge in der Regel um so höher ist, je niedriger die gemessene Feuchte ist. Zur genauen Regelung der Papierfeuchte auf den gewünschten Wert ist vorzugsweise ein zwischen der Befeuchtungseinrichtung und der Beleimungsposition angeordneter zweiter Feuchtesensor vorgesehen. Weiterhin kann vorzugsweise ein nach der Beleimungsposition angeordneter dritter Feuchtesensor vorgesehen sein, um eine Regelung in Abhängigkeit der Feuchte des beleimten Papiers vornehmen zu können. Durch eine kontinuierliche online-Regelung kann eine Unterbrechung der Produktion vermieden werden.For this purpose, the paper feed unit expediently has one in front of the Moisture device arranged first moisture sensor for measuring the paper moisture on, whereby the amount of humidification is usually higher, the lower the measured humidity.
