Abstract

The invention relates to a gluing device for covering sheets for connecting filter plugs and cigarettes, use being made of a transfer roller which is provided with an impression and intended for transferring a corresponding glue pattern onto the covering-paper web. The aim is to improve the glue transfer. This is achieved by a supply chamber (3) which is kept under superatmospheric pressure with the glue and through which the transfer roller (2) runs. In this arrangement, use is made of a glue pump (22) which is controlled, in terms of its delivery capacity, in dependence on the speed of rotation of the transfer roller. The impression is thus more or less overfilled, in dependence on the speed of rotation, with glue such that the latter, after the passage of a doctor blade (8), expands up to an application zone (13), and extends out of the impression, to such an extent that reliable contact with the paper web (19) is ensured. <IMAGE>

Description

Die Erfindung betrifft eine Leimauftragvorrichtung zum Auftragen flüssigen Leims, insbesondere in Form eines Leimbildes, auf eine Bahn aus Papier, Kunststoff, Karton oder dergleichen, mit einer Leim aus einer Vorratskammer in einer Gravur aufnehmenden und den Leim in einer Auftragzone in Zusammenwirkung mit einer Gegenwalze aus der Gravur auf die Bahn auftragenden Übertragungswalze.The invention relates to a glue application device for applying liquid glue, in particular in the form of a glue pattern, to a web of paper, plastic, cardboard or the like, with a glue from a storage chamber in an engraving and the glue in an application zone in cooperation with a counter roller the engraving on the transfer roller applying the web.

Eine Vorrichtung der oben bezeichneten Art wird bevorzugt als Bestandteil einer Filteransetzmaschine für Zigaretten eingesetzt. Sie soll flüssigen Leim, vorzugsweise wässrigen Polyvinylacetatleim, fortlaufend auf einen Belagpapierstreifen auftragen, der anschließend in Belagblättchen zum Verbinden von Tabakstöcken und Filterstopfen zerschnitten wird. Darüber hinaus können mit einer derartigen Vorrichtung aber auch fließfähige Massen der unterschiedlichsten Art auf Bahnen fortlaufend aufgetragen werden.A device of the type described above is preferably used as part of a filter attachment machine for cigarettes. It is intended to continuously apply liquid glue, preferably aqueous polyvinyl acetate glue, to a topping paper strip, which is then cut into topping sheets for connecting tobacco sticks and filter plugs. In addition, with such a device, flowable masses of the most varied types can also be continuously applied to webs.

Der Erfindung liegt die Aufgabe zugrunde, bei allen Betriebszuständen einer derartigen Maschine einen einwandfreien Leimauftrag bzw. ein einwandfreies Leimbild auf dem Belagpapierstreifen zu erzeugen.The invention has for its object to produce a perfect glue application or a perfect glue pattern on the covering paper strip in all operating conditions of such a machine.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorratskammer an eine Leimzufuhrleitung angeschlossen ist, in die ein einen Überdruck in der Vorratskammer aufrechterhaltendes Förderorgan integriert ist.
Um zu erreichen, daß auch bei höheren Walzendrehzahlen der in die Walzengravur mit Überdruck eingedrückte Leim sich auf der Wegstrecke vom Auslauf der Walze aus dem Vorratsbehälter bis zur Auftragzone an der Papierbahn in der dafür zur Verfügung stehenden kürzeren Zeit wieder entspannt und die Bahn benetzt, wird außerdem vorgeschlagen, daß das Förderorgan als in Abhängigkeit von der Drehzahl der Übertragungswalze gesteuerte Pumpe ausgebildet ist.
Dabei ist nach einer Weiterbildung der Pumpe zweckmäßigerweise ein bei ansteigender Walzendrehzahl die Förderleistung erhöhendes und bei abfallender Walzendrehzahl die Förderleistung der Pumpe verminderndes Steuermittel zugeordnet. Auf diese Weise wird der Leim bzw. die von ihm eingeschlossene Luft in der Walzengravur derart komponiert, daß er sich in der entsprechend zur Verfügung stehenden Zeit bis zur Übertragung an die Papierbahn soweit entspannt, daß er die Bahnoberfläche mit Sicherheit benetzt.
Zweckmäßigerweise ist zur Kontrolle der Druckverhältnisse in der Vorratskammer diese mit einem Drucküberwachungsanschluß versehen.
Eine drehzahlabhängige gezielte Überfüllung der Walzengravur wird nach einer Weiterbildung unterstützt und vollendet, indem die Vorratskammer an der Austrittsseite der Übertragungswalze gegen deren Mantelfläche durch einen Schaber abgedichtet ist, welcher den bis zum Auslauf aus der Vorratskammer zusätzlich an der Oberfläche der Übertragungswalze haftenden Leimüberschuß abstreicht.
Um den in der Vorratskammer befindlichen, von der Übertragungswalze nicht abgeförderten überschüssigen Leim im Förderkreislauf zu halten, ist außerdem vorgesehen, daß die Vorratskammer an der Eintrittsseite der Übertragungswalze relativ zu deren Mantelfläche eine in einen Sammelbehälter einmündende Spaltöffnung aufweist, aus dem dann der Leimüberschuß in einen den Kreislauf schließenden Hauptsammelbehälter zurückgeführt wird.This object is achieved in that the storage chamber is connected to a glue supply line, in which a conveying member maintaining an overpressure in the storage chamber is integrated.
In order to ensure that, even at higher roller speeds, the glue pressed into the roller engraving with overpressure relaxes in the shorter time available on the path from the outlet of the roller from the storage container to the application zone on the paper web and wets the web, It is also proposed that the conveyor is designed as a pump controlled as a function of the speed of the transfer roller.
According to a further development of the pump, a control means which increases the delivery rate when the roller speed increases and which reduces the delivery rate of the pump when the roller speed falls is expediently assigned. In this way, the glue or the air enclosed by it is composed in the roller engraving in such a way that it relaxes in the time available until it is transferred to the paper web to such an extent that it wets the web surface with certainty.
To control the pressure conditions in the storage chamber, it is expediently provided with a pressure monitoring connection.
A speed-dependent, targeted overfilling of the roller engraving is supported and completed according to a further development in that the storage chamber on the outlet side of the transfer roller is sealed against its outer surface by a scraper, which wipes off the excess glue which adheres to the surface of the transfer roller until it leaves the storage chamber.
In order to keep the excess glue in the supply circuit, which is not conveyed away by the transfer roller, in the conveyor circuit, it is also provided that the supply chamber on the inlet side of the transfer roller has a gap opening opening into a collecting container relative to its outer surface, from which the excess glue then flows into one the main collection container closing the circuit is returned.

Der mit der Erfindung erzielte Vorteil besteht darin, daß der von der Maschinendrehzahl und damit von der Walzendrehzahl der Übertragungswalze abhängige Kammerdruck bzw. Leimdruck in jedem Betriebszustand der Maschine so hoch ist, daß immer eine entsprechende Überfüllung der Gravur erzeugt wird, derart, daß sich nach dem Passieren des Schabers oder Rakels der Leim in jedem Fall soweit wieder entspannt, daß er aus der Gravur herausragt bzw. herausquillt und dabei mit Sicherheit auf das Belagpapier übertragen wird.The advantage achieved by the invention is that the chamber pressure or glue pressure, which is dependent on the machine speed and thus on the roll speed of the transfer roll, is so high in every operating state of the machine that there is always one appropriate overfilling of the engraving is produced, such that after passing the scraper or squeegee, the glue in any case relaxes again to such an extent that it protrudes or swells out of the engraving and is thereby reliably transferred to the base paper.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.

Einer am Walzenmantel mit einer Gravur 1 versehenen Leim-Übertragungwalze 2 ist eine Leim-Vorratskammer 3 zugeordnet, in welche die um eine Achse 4 in Richtung des Pfeils 6 rotierende Übertragungswalze 2 im Bereich einer unterseitigen Spaltöffnung 7 in Drehrichtung eintritt und im Bereich eines oberseitigen Schabers oder Rakels 8 austritt.
Die Spaltöffnung 7 stellt eine Verbindung zwischen der Vorratskammer 3 und einem unteren Sammelbehälter 9 dar, welcher wiederum über eine Rücklaufbohrung 11 mit einem Leimreservoir 12 verbunden ist.
Im Bereich einer Leimauftragszone 13 wirkt die Übertragungswalze 2 mit einer um eine Achse 14 in Pfeilrichtung 16 rotierenden Gegenwalze 17 zusammen, zwischen denen eine in Förderrichtung 18 durchlaufende, zu beleimende Papierbahn 19 geführt ist.
An die Vorratskammer 3 ist eine Leimzufuhrleitung 21 angeschlossen, in die ein Förderorgan in Form einer Leimpumpe 22 integriert ist, welche Leim aus dem Leimreservoir 12 derart in die Vorratskammer 2 pumpt, daß darin immer ein Überdruck aufrecherhalten wird. Zur Überwachung dieses Überdrucks ist die Vorratskammer 3 mit einem Drucküberwachungsanschluß 23 versehen.
Die Drehzahl bzw. die Förderleistung der Pumpe 22 wird in Abhängigkeit von der Maschinengeschwindigkeit, in diesem Fall einer Filteransetzmaschine der Tabakindustrie bzw. von der Drehzahl der Übertragungswalze 2 durch ein Steuermittel 24 derart gesteuert, daß bei ansteigender Drehzahl der Übertragungswalze 2 die Förderleistung der Pumpe 22 und damit der Druck in der Vorratskammer 3 erhöht wird und bei abfallender Walzendrehzahl die Pumpendrehzahl und damit die Förderleistung vermindert wird.
Zu diesem Zweck ist das Steuermittel 24 steuerungsmäßig mit einem Vergleichsglied 26 verbunden, welchem ein Signal eines Drehzahlgebers 27 der Übertragungswalze 2 über einen Drehzahl/Spannungswandler 28 sowie ein Drucksignal aus der Vorratskammer 3 über einen Druck/Spannungswandler 29 zugeführt wird. Das Vergleichs- bzw. Differenzsignal des Vergleichsgliedes 26 aktiviert das Steuermittel 24 zu einer Erhöhung oder Verminderung der Pumpendrehzahl und damit zu einer entsprechenden Veränderung des Kammerdrucks in der Vorratskammer 3.
Auf diese Weise werden die Zwischenräume der Gravur 1 bei jeder Walzendrehzahl immer mit einem entsprechenden Überdruck derart überfüllt, daß nach dem Abstreifen des Leimüberschusses durch den Schaber 8 der unter Überdruck in der Gravur verbliebene Leim sich bis zur Auftragszone 13 soweit radial entspannt, daß eine einwandfreie Kontaktierung mit der Papierbahn in allen Drehzahlbereichen der Übertragungswalze 2 erfolgt.
Nicht aus der Vorratskammer 3 abgeförderter Leimüberschuß wird über die Spaltöffnung 7 in den Sammelbehälter 9 und über dessen Rücklaufbohrung 11 in das Leimreservoir 12 und damit in den Förderkreislauf zurückgeführt.A glue transfer roller 2, which is provided with an engraving 1 on the roller shell, is assigned a glue storage chamber 3, into which the transfer roller 2 rotating about an axis 4 in the direction of arrow 6 enters in the area of a gap opening 7 on the underside and in the area of an upper-side scraper or squeegee 8 emerges.
The gap opening 7 represents a connection between the storage chamber 3 and a lower collecting container 9, which in turn is connected to a glue reservoir 12 via a return bore 11.
In the area of a glue application zone 13, the transfer roller 2 interacts with a counter roller 17 rotating about an axis 14 in the direction of the arrow 16, between which a paper web 19 which is to be glued and runs in the conveying direction 18 is guided.
A glue supply line 21 is connected to the storage chamber 3, into which a conveying element in the form of a glue pump 22 is integrated, which pumps the glue from the glue reservoir 12 into the storage chamber 2 in such a way that an overpressure is always maintained therein. To monitor this overpressure, the storage chamber 3 is provided with a pressure monitoring connection 23.
The speed or the delivery rate of the pump 22 is controlled as a function of the machine speed, in this case a filter attachment machine of the tobacco industry or the speed of the transfer roller 2, by a control means 24 such that the delivery rate of the pump 22 increases as the speed of the transfer roller 2 increases and so that the pressure in the storage chamber 3 is increased and when the roller speed drops, the pump speed and thus the delivery rate is reduced.
For this purpose, the control means 24 is connected in terms of control to a comparison element 26 which receives a signal from a speed sensor 27 of the transfer roller 2 via a Speed / voltage converter 28 and a pressure signal from the storage chamber 3 via a pressure / voltage converter 29 is supplied. The comparison or difference signal of the comparison member 26 activates the control means 24 to increase or decrease the pump speed and thus to a corresponding change in the chamber pressure in the storage chamber 3.
In this way, the interstices of the engraving 1 are always overfilled with a corresponding overpressure at each roller speed in such a way that after the excess glue is scraped off by the scraper 8, the glue remaining under overpressure in the engraving relaxes radially to the application zone 13 to such an extent that a perfect one Contact is made with the paper web in all speed ranges of the transfer roller 2.
Excess glue not removed from the storage chamber 3 is returned via the gap opening 7 into the collecting container 9 and via its return bore 11 into the glue reservoir 12 and thus into the conveying circuit.
