Description

Die Erfindung betrifft eine Leimauftrageinrichtung für eine Maschine der Tabak verarbeitenden Industrie, umfassend eine an einer Leimwalze angeordnete Leimkammer, die relativ zu der Leimwalze nachstellbar ist, um Verschleiß einer an der Leimkammer angebrachten Abstreifeinrichtung auszugleichen. Die Erfindung betrifft weiterhin ein entsprechendes Leimauftragverfahren.The invention relates to a glue application device for a machine of the tobacco-processing industry, comprising a glue chamber arranged on a glue chamber, which is adjustable relative to the glue roller to compensate for wear of an attached to the glue chamber stripping. The invention further relates to a corresponding glue application method.

Eine Leimauftrageinrichtung für eine Maschine der Tabak verarbeitenden Industrie, insbesondere eine Filteransetzmaschine, ist beispielsweise aus DE 10 2008 019 434 A1 und EP 2 110 181 A2 bekannt.A glue application device for a machine of the tobacco-processing industry, in particular a filter attachment machine, is for example made DE 10 2008 019 434 A1 and EP 2 110 181 A2 known.

US 4 485 132 betrifft eine Maschine zum Beschichten von Metallstreifen. Die Verstellung einer Abstreifeinrichtung (doctor blade) wird gemessen und anhand dieses Messsignals die Nachstellung der Farbkammer geregelt. US 4,485,132 relates to a machine for coating metal strips. The adjustment of a doctor blade is measured and the adjustment of the ink chamber is regulated on the basis of this measurement signal.

Wenn die Abstreifeinrichtung verschlissen ist, kommt es zu einer Beeinträchtigung der Funktion und gegebenenfalls zu unkontrolliertem Leimauftrag. Unter Umständen kann es zu einem Anschlagen der Leimkammer an der Leimwalze und im schlimmsten Fall zu einer Beschädigung der Leimwalze kommen. Um dies zu verhindern, können kurze Wechselintervalle für die Abstreifeinrichtung vorgesehen werden, was jedoch einen häufigen Stillstand der Maschine mit sich bringt.If the scraper is worn, it will affect the function and possibly uncontrolled glue application. Under certain circumstances, it can come to a striking of the glue chamber on the glue roller and in the worst case to damage the glue roller. To prevent this, short change intervals can be provided for the stripping device, which, however, brings about a frequent standstill of the machine.

Die Aufgabe der Erfindung besteht darin, eine effiziente und funktionssichere Leimauftrageinrichtung bereitzustellen, bei der eine Beschädigung der Leimwalze verhindert werden kann. Die Erfindung löst diese Aufgabe mit den Mitteln der unabhängigen Ansprüche. Mittels der erfindungsgemäßen Erfassung des Verstellwegs der Leimkammer kann der Verschleiß der Abstreifeinrichtung quantitativ in Form eines entsprechenden Wegwerts erfasst werden. Wenn der erfasste Wegwert eine vorgegebene Bedingung erfüllt, die anzeigt, dass der Verschleiß der Abstreifeinrichtung einen bestimmten maximal zulässigen Wert erreicht hat, wird ein Signal ausgegeben, um eine Auswechslung der Abstreifeinrichtung zu veranlassen. Auf diese Weise kann zuverlässig verhindert werden, dass es zu einer Überschreitung des maximal tolerierbaren Verschleißes der Abstreifeinrichtung und infolgedessen zu einem Anschlagen der Leimkammer an der Leimwalze kommt.The object of the invention is to provide an efficient and functionally reliable glue application device in which damage to the glue roller can be prevented. The invention solves this problem with the means of the independent claims. By means of the detection of the adjustment path of the glue chamber according to the invention, the wear of the stripping device can be detected quantitatively in the form of a corresponding path value. When the detected travel value satisfies a predetermined condition indicating that the wear of the scraper has reached a certain maximum allowable value, a signal is issued to cause replacement of the scraper. In this way it can be reliably prevented that it comes to exceeding the maximum tolerable wear of the stripping device and consequently to a striking of the glue chamber on the glue roller.

Erfindungsgemäß wird bei Entnahme einer bestimmten Abstreifeinrichtung, bzw. einer entsprechenden Baueinheit, insbesondere der Leimkammer, der Wegwert zu dieser Abstreifeinrichtung gespeichert. Insbesondere bei der Verwendung einer Mehrzahl von Abstreifeinrichtungen kann vorzugsweise eine entsprechende Mehrzahl von Wegwerten gespeichert werden. Auf diese Weise ist der individuelle Wegwert jeder Abstreifeinrichtung zu einem späteren Zeitpunkt verfügbar; eine aufwändige Bestimmung und Eingabe des aktuellen Verschleißzustandes einer Abstreifeinrichtung kann dadurch vermieden werden. Insbesondere kann beim Einsetzen einer bestimmten Abstreifeinrichtung vorzugsweise ein zu dieser Abstreifeinrichtung gespeicherter Wegwert abgerufen und in der Maschinensteuerung gesetzt werden. Beim Einsetzen einer neuen, unverschlissenen Abstreifeinrichtung wird der Wegwert zweckmäßigerweise auf einen vorbestimmten Wert gesetzt, der einem Nullwert des Verschleißes entspricht. Insbesondere bei der Verwendung einer Mehrzahl von Abstreifeinrichtungen ist es vorteilhaft, ein Kennzeichnungsmittel zur individuellen Kennzeichnung jeder einzelnen Abstreifeinrichtung, bzw. einer entsprechenden Baueinheit, insbesondere der Leimkammer, vorzusehen. Mittels eines vorteilhaften Sensors kann dieses Kennzeichnungsmittel automatisch detektiert und die individuelle Kennzeichnung bestimmt werden, so dass die Maschinensteuerung insbesondere den der Abstreifeinrichtung zugeordneten Wegwert setzen kann, wodurch unbeabsichtigte Fehleinstellungen durch den Bediener vermieden werden können.According to the removal value of a certain stripping, or a corresponding assembly, in particular the glue chamber, the Wegwert stored to this stripping. In particular, when using a plurality of stripping means, preferably a corresponding plurality of displacement values can be stored. In this way, the individual path value of each scraping device is available at a later time; a complex determination and input of the current state of wear of a stripping device can be avoided. In particular, when a certain wiper device is inserted, a path value stored for this wiper device can preferably be called up and set in the machine control. When inserting a new, unworn stripping device, the path value is expediently set to a predetermined value, which corresponds to a zero value of the wear. In particular, when using a plurality of stripping means, it is advantageous to provide a marking means for individual identification of each stripping device, or a corresponding structural unit, in particular the glue chamber. By means of an advantageous sensor, this identification means can be detected automatically and the individual identification can be determined, so that the In particular, the machine control can set the path value assigned to the stripping device, as a result of which unintentional misadjustments by the operator can be avoided.

Die erfindungsgemäße Leimauftrageinrichtung findet vorzugsweise Anwendung in einer Maschine der Tabak verarbeitenden Industrie, in der Beleimung eines Materialstreifens, insbesondere eines Papierstreifens, beispielsweise dem Belagpapier von Filterzigaretten. Die Erfindung kann daher insbesondere in Filteransetzmaschinen zur Herstellung von Filterzigaretten angewendet werden.The glue application device according to the invention is preferably used in a machine of the tobacco-processing industry, in the gluing of a material strip, in particular a paper strip, for example the tipping paper of filter cigarettes. The invention can therefore be applied in particular in filter attachment machines for the production of filter cigarettes.

a schematic representation of a glue application device in a further embodiment.

Der in Fig. 1 gezeigte Ausschnitt einer Filteransetzmaschine 10 zeigt eine Leimauftrageinrichtung 11, die einen Leimtopf 12 und eine Steuereinrichtung 13 umfasst. Der Leimtopf 12, der insbesondere eine auswechselbare Einheit sein kann, umfasst einen Leimbehälter 14, eine in dem Leimbehälter 14 rotierbar gelagerte Leimwalze 15 und eine Leimkammer 16 zum Auftragen von Leim aus einem in der Leimkammer 16 gebildeten Hohlraum 17 auf die Leimwalze 15. Die Leimkammer 16 ist zu diesem Zweck am Umfang der Leimwalze 15 an diese anliegend angeordnet und wird mittels einer Andrückeinrichtung 18, die einen Stößel 19 und eine an einem maschinenfesten Gegenlager 32 abgestützte Krafterzeugungseinrichtung 20 zur Erzeugung einer Andrückkraft umfasst, an die Außenfläche der Leimwalze 15 angedrückt. Die Krafterzeugungseinrichtung 20 ist vorzugsweise ein insbesondere pneumatischer Zylinder, kann jedoch beispielsweise auch eine Feder oder eine elektrisch oder elektromagnetisch betriebene Einrichtung sein. Die Leimkammer 16 wird mittels nicht gezeigter Einrichtungen mit Leim versorgt.The in Fig. 1 shown section of a filter attachment machine 10 shows a glue application device 11, which comprises a glue pot 12 and a control device 13. The glue pot 12, which may in particular be an exchangeable unit, comprises a glue container 14, a glue roller 15 rotatably mounted in the glue container 14 and a glue chamber 16 for applying glue from a cavity 17 formed in the glue chamber 16 to the glue roller 15. The glue chamber 16 is arranged for this purpose on the circumference of the glue roller 15 adjacent to this and is by means of a pressure device 18, which has a plunger 19 and a force-on a machine-fixed counter-bearing 32 force generating device 20 for generating a pressing force, pressed against the outer surface of the glue roller 15. The force generating device 20 is preferably a particular pneumatic cylinder, but may for example be a spring or an electrically or electromagnetically operated device. The glue chamber 16 is supplied with glue by means not shown.

Die rotierende Leimwalze 15 nimmt mittels an ihrer Außenfläche vorgesehenen Näpfchen Leim aus der Leimkammer 16 auf. Überschüssiger Leim wird mittels einer Abstreifeinrichtung, die im vorliegenden Beispiel von zwei Abstreifern 21, 22 bzw. Schabern gebildet ist, abgestreift. Abstreifeinrichtung bezeichnet den gesamten an einer Leimkammer 16 vorgesehenen Satz von Abstreifern 21, 22. In anderen Ausführungsformen kann die Abstreifeinrichtung von nur einem Abstreifer, oder mehr als zwei Abstreifern, gebildet sein. Der von der Leimwalze 15 aufgenommene und aus der Leimkammer 16 heraustransportierte Leim wird an einen am Außenumfang der Leimwalze 15 anliegenden, kontinuierlich geförderten Belagpapierstreifen 23 abgegeben.The rotating glue roller 15 receives glue from the glue chamber 16 by means of cups provided on its outer surface. Excess glue is stripped by means of a stripping device, which in the present example is formed by two scrapers 21, 22 or scrapers. Scraper means the entire set of scrapers 21, 22 provided on a glue chamber 16. In other embodiments, the scraper may be formed by only one scraper, or more than two scrapers. The glue taken up by the glue roller 15 and transported out of the glue chamber 16 is delivered to a continuously conveyed tipping paper strip 23 lying on the outer circumference of the glue roller 15.

Aufgrund des kontinuierlichen Andrückens der Abstreifer 21, 22 an die Leimwalze 15 durch die Andrückvorrichtung 18 unterliegen die Abstreifer 21, 22 einem Reibungsverschleiß. Um den Anpressdruck kontinuierlich aufrechtzuerhalten, ist die Leimkammer 16, beispielsweise über den in dem Leimbehälter verschiebbar gelagerten Stößel 19, insbesondere in Pfeilrichtung, d.h. relativ zur Leimwalze 15 radial, verschiebbar gelagert und wird durch die Andrückvorrichtung 18 mit einer Vorspannung beaufschlagt. Auch eine schwenkbar gelagerte Leimkammer 16 ist denkbar.Due to the continuous pressing of the scrapers 21, 22 to the glue roller 15 by the pressing device 18, the scrapers 21, 22 are subject to frictional wear. In order to maintain the contact pressure continuously, the glue chamber 16, for example via the displaceably mounted in the glue container tappet 19, in particular in the arrow direction, i. mounted radially displaceable relative to the glue roller 15 and is biased by the pressing device 18. Also, a pivotally mounted glue chamber 16 is conceivable.

Die Leimauftrageinrichtung 11 umfasst vorzugsweise eine Messeinrichtung 28 zur Messung des Verschiebungsweges der Leimkammer 16. Die Messeinrichtung 28 umfasst in der in den Figuren gezeigten Ausführungsform eine in fester Verbindung zu der Leimkammer 16 stehende Messfläche 25, die im vorliegenden Beispiel von einer an dem Stößel 19 befestigten Platte 26 gebildet wird. Die Messfläche 25 kann alternativ auch von der Rückseite der Leimkammer 16 oder einer anderen geeigneten Oberfläche gebildet werden. In dem Leimtopf 12 ist weiterhin ein Abstandssensor 27 vorgesehen, der relativ zu dem Leimbehälter 14 feststeht und zur Messung des Abstands zu der Messfläche 25 geeignet ist. Der Abstandssensor 27 kann vorzugsweise ein Wirbelstromsensor oder ein anderer geeigneter Abstandssensor sein. Selbstverständlich kann alternativ der Abstandssensor 27 in fester Verbindung zu der Leimkammer 16 stehen und die Messfläche 25 relativ zu dem Leimbehälter 14 feststehen. Die Messeinrichtung 28 kann allgemein auch in Form eines Messgebers und eines mit dem Messgeber zusammenwirkenden Messnehmers realisiert sein.The glue application device 11 preferably comprises a measuring device 28 for measuring the displacement path of the glue chamber 16. In the embodiment shown in the figures, the measuring device 28 comprises a measuring surface 25 which is fixedly connected to the glue chamber 16 and which in the present example is formed by a plate 26 fastened to the plunger 19. The measuring surface 25 may alternatively also be formed by the rear side of the glue chamber 16 or another suitable surface. In the glue pot 12, a distance sensor 27 is further provided, which is fixed relative to the glue container 14 and is suitable for measuring the distance to the measuring surface 25. The distance sensor 27 may preferably be an eddy current sensor or another suitable distance sensor. Of course, alternatively, the distance sensor 27 may be in fixed connection to the glue chamber 16 and the measuring surface 25 may be fixed relative to the glue container 14. The measuring device 28 can generally also be realized in the form of a measuring transmitter and a sensor cooperating with the measuring transmitter.

Zur Bestimmung des Verschiebungswegs der Leimkammer 16 ist nicht zwingend eine Messeinrichtung 28 erforderlich. Der Verschiebungsweg kann gegebenenfalls auch aus anderweitig verfügbarer Information ermittelt werden. Wenn beispielsweise die Krafterzeugungseinrichtung 20 einen elektrischen Schrittmotor umfasst, kann entsprechende Weginformation direkt von dem Schrittmotor bzw. der Schrittmotorsteuerung an die Steuereinrichtung 13 übermittelt werden.To determine the displacement path of the glue chamber 16, a measuring device 28 is not necessarily required. If appropriate, the displacement path can also be determined from information that is otherwise available. If, for example, the force-generating device 20 comprises an electric stepping motor, corresponding travel information can be transmitted directly from the stepping motor or the stepping motor control to the control device 13.

Das gemessene bzw. ermittelte Abstandssignal wird von dem Abstandssensor 27 an die Steuereinrichtung 13 übermittelt. Die Steuereinrichtung 13 ist insbesondere eine elektronische programmierte Steuerung auf der Grundlage eines Mikroprozessors bzw. Microcontrollers, insbesondere eine SPS-Steuerung. Vorzugsweise ist die Steuereinrichtung 13 in der zentralen Maschinensteuerung realisiert. Es kann sich jedoch beispielsweise auch um eine separate Steuereinheit in dem Leimtopf 12 handeln.The measured or determined distance signal is transmitted from the distance sensor 27 to the control device 13. The control device 13 is in particular an electronic programmed control based on a microprocessor or microcontroller, in particular a PLC control. Preferably the control device 13 is realized in the central machine control. However, it may also be, for example, a separate control unit in the glue pot 12.

In der Steuereinrichtung 13 wird beim Einsetzen eines Leimtopfes 12 mit neuen, unverschlissenen Abstreifern 21, 22 der dann ermittelte Abstandswert d0 als Anfangsabstand in einem Speicherbereich 24 gespeichert. Die im Betrieb ermittelten Abstandswerte d werden laufend oder in definierten Zeitabständen mit dem ermittelten Anfangsabstand d0 verglichen. Als Wegwert W, der den aktuellen Verschleißzustand der Abstreifeinrichtung 21, 22 beschreibt, wird der Betrag der Differenz zwischen dem Anfangsabstand d0 und dem gemessenen Abstand d ermittelt: W=|d0-d|. Der aktuelle Wegwert W wird zweckmäßigerweise in einem Speicherbereich 25 gespeichert. Wenn der Wegwert W einen vorbestimmten Wert Wmax überschreitet, stellt die Steuereinrichtung 13 fest, dass der maximal tolerierbare Verschleiß der Abstreifer 21, 22 erreicht ist, und führt durch Ausgabe eines entsprechenden Signals geeignete Maßnahmen aus. Beispielsweise kann auf einem Bedienterminal 29 ein Hinweis angezeigt werden, dass die Abstreifer 21, 22 erneuert werden müssen. Die Steuereinrichtung 13 kann auch einen Maschinenstopp veranlassen oder eine andere geeignete Maßnahme ausführen.In the control device 13, when a glue pot 12 is inserted with new, unworn scrapers 21, 22, the then determined distance value d0 is stored as a starting distance in a memory area 24. The distance values d determined during operation are compared with the determined initial distance d0 continuously or at defined time intervals. As the path value W, which describes the current state of wear of the stripping device 21, 22, the amount of the difference between the initial distance d0 and the measured distance d is determined: W = | d0-d |. The current path value W is expediently stored in a memory area 25. If the travel value W exceeds a predetermined value Wmax, the control device 13 determines that the maximum tolerable wear of the scrapers 21, 22 has been reached, and carries out suitable measures by outputting a corresponding signal. For example, an indication can be displayed on an operating terminal 29 that the scrapers 21, 22 must be replaced. The controller 13 may also initiate a machine stop or perform another suitable action.

Wenn der Leimtopf 12 aus der Maschine 10 entnommen werden muss, beispielsweise zur Reinigung oder infolge eines Papierrisses, wird der aktuelle Wegwert W der Abstreifeinrichtung 21, 22 in der der Steuereinrichtung 13 in einem entsprechenden Speicherbereich 25 gespeichert. Wenn der Leimtopf 12 mit denselben Abstreifern 21, 22 wieder eingesetzt wird, wird zunächst der Anfangsabstand d0 neu ermittelt. Der dann im Betrieb ermittelte aktuelle Wegwert wird dann zu dem in dem Speicherbereich 25 gespeicherten Wegwert addiert, um den aktuellen Gesamtwegwert der Abstreifeinrichtung 21, 22 zu erhalten und mit dem maximal zulässigen Wegwert Wmax zu vergleichen. Der aktuelle Gesamtwegwert W der Abstreifeinrichtung 21, 22 wird zweckmäßigerweise in dem Speicherbereich 25 gespeichert.When the glue pot 12 has to be removed from the machine 10, for example for cleaning or as a result of a paper tear, the current path value W of the stripping device 21, 22 is stored in the control device 13 in a corresponding memory area 25. When the glue pot 12 is reinserted with the same scrapers 21, 22, the initial distance d0 is first determined again. The then determined during operation current Wegwert then becomes the in the Memory area 25 stored Wegwert added to obtain the current total path value of the stripping device 21, 22 and to compare with the maximum permissible path value Wmax. The current total path value W of the stripping device 21, 22 is expediently stored in the memory area 25.

Wenn ein Leimtopf 12 mit einer neuen, unverschlissenen Abstreifeinrichtung 21, 22 in die Maschine 10 eingesetzt wird, setzt die Steuereinrichtung 13 den zugehörigen aktuellen (Gesamt-)Wegwert in dem Speicherbereich 25 auf Null und ermittelt den Anfangsabstand d0 neu, der dann in dem Speicherbereich 24 gespeichert wird. Beim Einsetzen eines Leimtopfes 12 in die Maschine 10 kann beispielsweise eine Abfrage an den Bediener erfolgen, ob die Abstreifer 21, 22 erneuert wurden. Es ist auch denkbar, dies auf geeignete Weise zu detektieren, um nicht auf die Eingabe eines Bedieners angewiesen zu sein.When a glue pot 12 with a new, unworn stripper 21, 22 is inserted into the machine 10, the controller 13 sets the associated current (total) path value in the memory area 25 to zero and recalculates the initial distance d0, which is then in the memory area 24 is stored. When inserting a glue pot 12 in the machine 10, for example, a query to the operator, whether the scrapers 21, 22 have been renewed. It is also conceivable to detect this in a suitable manner in order not to depend on the input of an operator.

Die Ausführungsform gemäß Figur 2 ist insbesondere geeignet, wenn für die Maschine 10 eine Mehrzahl, hier beispielsweise zwei Leimtöpfe 12 vorgesehen sind. Wenn eine der Leimtöpfe 12 beispielsweise zur Reinigung entnommen wird, kann der andere Leimtopf 12 eingesetzt werden, wodurch die Stillstandzeit der Maschine reduziert werden kann.The embodiment according to FIG. 2 is particularly suitable when a plurality, here for example two glue pots 12 are provided for the machine 10. For example, if one of the glue pots 12 is removed for cleaning, the other glue pot 12 can be used, whereby the downtime of the machine can be reduced.

In dieser Ausführungsform weist der bzw. jeder Leimtopf 12, hier am Leimbehälter 14, ein Kennzeichnungsmittel 30 auf, das eine eindeutige Kennzeichnung des Leimtopfes 12 und damit der dem Leimtopf zugeordneten Abstreifeinrichtung 21, 22 enthält. Das Kennzeichnungsmittel 30 kann beispielsweise ein Transponder oder eine einfache mechanische Kodierung, beispielsweise mittels unterschiedlicher Anordnung eines Stiftes oder dergleichen, sein.In this embodiment, the or each glue pot 12, here on the glue container 14, a marking means 30 which contains a unique identification of the glue pot 12 and thus of the glue pot associated scraper 21, 22. The identification means 30 may be for example a transponder or a simple mechanical coding, for example by means of a different arrangement of a pin or the like.

Die Leimauftrageinrichtung 11 umfasst des Weiteren einen Sensor 31, der zur Ermittlung der in dem Kennzeichnungsmittel 30 gespeicherten Kennzeichnung eingerichtet ist. Im vorliegenden Beispiel kann die Steuereinrichtung mittels des von dem Sensor 31 ausgegebenen Signals feststellen, ob der eine oder der andere der beiden Leimtöpfe 12 in die Maschine eingesetzt ist. Die Steuereinrichtung 13 enthält für jeden der verwendeten Leimtöpfe 12 einen eigenen Speicherbereich 25a, 25b für den entsprechenden aktuellen (Gesamt-)Wegwert Wa, Wb der diesem Leimtopf 12 zugeordneten Abstreifvorrichtung. Auf diese Weise kann der individuelle Verschleiß jeder einem bestimmten Leimtopf 12 zugeordneten Abstreifeinrichtung 21, 22 individuell erfasst, gespeichert und ausgewertet werden.The glue application device 11 further comprises a sensor 31, which is set up to determine the identification stored in the identification means 30. In the present example, the control device can determine, by means of the signal output by the sensor 31, whether one or the other of the two glue pots 12 is inserted into the machine. For each of the glue pots 12 used, the control device 13 contains its own memory area 25a, 25b for the corresponding current (total) path value Wa, Wb of the stripping device assigned to this glue pot 12. In this way, the individual wear of each of a particular glue pot 12 associated stripping device 21, 22 are detected, stored and evaluated individually.

In einer nicht gezeigten Ausführungsform kann das Kennzeichnungsmittel 30 alternativ an der Leimkammer 16 oder der Abstreifeinrichtung 21, 22 angeordnet sein.In an embodiment not shown, the identification means 30 may alternatively be arranged on the glue chamber 16 or the stripping device 21, 22.
