Ausgehend von diesem Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, die Handhabung von Beleimungseinrichtungen der Tabak verarbeitenden Industrie beim Einsatz an Maschinen der Tabak verarbeitenden Industrie, insbesondere Filteransetzmaschinen, zu verbessern, wobei insbesondere auf einfache Weise der Sauberkeitsgrad erhöht werden soll. Diese Aufgabe wird gelöst durch die Merkmale des Anspruchs 1.Based on this state of the art, the object of the present invention is to improve the handling of gluing devices in the tobacco processing industry when used on machines in the tobacco processing industry, in particular filter attaching machines, in particular to increase the degree of cleanliness in a simple manner. This object is achieved by the features of claim 1.
Bei einer Einrichtung zum Auftragen von Leim auf einen Materialstreifen der Tabak verarbeitenden Industrie mit einem in einem Gehäuse angeordneten Leimauftragungsorgan, insbesondere Rasterwalze, wobei mittels einer mit dem Gehäuse verbundenen Zuführleitung Leim zum Gehäuse oder Leimauftragungsorgan gefördert wird oder ist und/oder wobei mittels einer mit dem Gehäuse verbundenen Abführleitung Leim aus dem Gehäuse abgefördert wird oder ist, ist vorgesehen, dass in der Zuführleitung wenigstens eine Fließsperreinrichtung vorgesehen ist, derart, dass ein Fließen oder Rückfließen des in der Zuführleitung geförderten oder förderbaren Leims verhindert oder reduziert wird oder ist und/oder in der Abführleitung wenigstens eine Fließsperreinrichtung vorgesehen ist, derart, dass ein Fließen oder Rückfließen des in der Abführleitung geförderten oder förderbaren Leims verhindert oder reduziert wird oder ist.In a device for applying glue to a strip of material in the tobacco processing industry with a glue application element arranged in a housing, in particular an anilox roller, glue being conveyed to the housing or glue application element by means of a feed line connected to the housing or is and / or where glue is or is conveyed away from the housing by means of a discharge line connected to the housing, it is provided that at least one flow stop device is provided in the feed line, such that a flow or backflow of the glue conveyed or conveyable in the feed line is or is prevented or reduced and / or at least one flow blocking device is provided in the discharge line, such that a flow or backflow of the glue conveyed or conveyable in the discharge line is or is prevented or reduced.
Hierbei ist vorgesehen, dass während eines Produktionsstopps einer Maschine der Tabak verarbeitenden Industrie, insbesondere Filteransetzmaschine, ein Beleimungsapparat, der ein äußeres Gehäuse und in dem Gehäuse ein Leimauftragungsorgan, beispielsweise in Form einer Rasterwalze, aufweist, komplett von der Maschine entnommen bzw. entfernt wird, wobei hierzu die Zuführleitung und/oder die Abführleitung lösbar mit dem Gehäuse des Beleimungsapparates gekoppelt sind, wodurch unter Verwendung der Fließsperreinrichtungen ein unkontrolliertes Austreten von Leim aus dem Gehäuse bzw. Leimtopf des Beleimungsapparates oder aus der Zuführleitung und/oder der Abführleitung an den, insbesondere offenen, Verbindungsstellen verhindert wird. Da kein Leim aus den Leitungen oder aus dem Gehäuse aufgrund der vorgesehenen Leimfließsperreinrichtungen an den Verbindungsstellen austritt, wird die Sauberkeit im Bereich des Beleimungsapparates an der Maschine deutlich erhöht. Somit wird auch die Maschine sauber gehalten und die Handhabung des Beleimungsapparates verbessert.It is provided here that during a production stop of a machine in the tobacco processing industry, in particular a filter attachment machine, a gluing apparatus, which has an outer housing and a glue application element, for example in the form of an anilox roller, is completely removed from the machine, for this purpose, the supply line and / or the discharge line are detachably coupled to the housing of the gluing apparatus, whereby an uncontrolled leakage of glue from the housing or glue pot of the gluing apparatus or from the supply line and / or the discharge line to the, in particular open, , Joints is prevented. Since no glue escapes from the lines or from the housing due to the glue flow blocking devices provided at the connection points, the cleanliness in the area of the gluing apparatus on the machine is significantly increased. This also keeps the machine clean and improves the handling of the gluing apparatus.
Vorzugsweise ist die Fließsperreinrichtung in der Zuführleitung zwischen einer Pumpe, insbesondere Druckpumpe, und dem Gehäuse und/oder ist die Fließsperreinrichtung in der Abführleitung zwischen einer Pumpe, insbesondere Saugpumpe, und dem Gehäuse angeordnet. Hierbei sind die Pumpe der Zuführleitung und die Pumpe der Abführleitung außerhalb des Gehäuses, d.h. gehäuseextern, und insbesondere auf der Maschinenseite der Maschine, angeordnet.The flow stop device is preferably arranged in the supply line between a pump, in particular a pressure pump, and the housing and / or the flow stop device is arranged in the discharge line between a pump, in particular a suction pump, and the housing. Here, the pump of the feed line and the pump of the discharge line are arranged outside the housing, ie outside the housing, and in particular on the machine side of the machine.
Darüber hinaus zeichnet sich eine Weiterbildung dadurch aus, dass die Fließsperreinrichtung als eine, insbesondere mit einem gegenüber dem Leitungsquerschnitt der Zuführleitung oder der Abführleitung ausgebildeten, Verengung oder als Leitungsverengungseinrichtung ausgebildet ist. Durch eine gezielte Verengung des Durchflussquerschnitts in der Zuführleitung und/oder in der Abführleitung wird ebenfalls ein Fließen oder ein Zurückfließen des Leims in den Versorgungsleitungen verhindert.In addition, a further development is characterized in that the flow barrier device is designed as a constriction, in particular with a constriction or a line constriction device, which is configured with respect to the line cross-section of the supply line or the discharge line. A targeted narrowing of the flow cross-section in the supply line and / or in the discharge line also prevents the glue from flowing or flowing back into the supply lines.
Dazu ist weiterhin vorgesehen, dass die Leitungsverengungseinrichtung als Fließsperrscheibe oder als, vorzugsweise steuerbares oder regelbares, Ventil ausgebildet ist. Hierbei ist die Fließsperrscheibe vorzugsweise elastisch, wobei die Fließsperrscheibe selbstöffnend ausgebildet ist, so dass bei Anlegen eines Förderdrucks oder Saugdrucks Leim durch die Sperrscheibe unter Förderung des Leims hindurchtritt, während beim Abschalten des Förderdrucks die Sperrscheibe selbsttätig den Durchtritt oder den Austritt von Leim an der Sperrscheibe verhindert. Hierzu ist beispielsweise die Fließsperrscheibe als elastische Scheibe mit einem oder mehreren Schlitzen ausgebildet. Ein Fließen des Leims in den Versorgungsleitungen, d.h. in der Zuführleitung und in der Abführleitung kann auch durch ein schaltbares oder einstellbares Ventil erreicht werden, so dass vor Entnahme des Beleimungsapparates das Ventil geschlossen wird bzw. ist, so dass in den Versorgungsleitungen kein Leim gefördert wird, wodurch auch kein Leim an der Trennstelle der Versorgungsleitung bzw. der Zuführleitung und der Abführleitung aus dem Gehäuse oder den Leitungen austritt.For this purpose, it is further provided that the line constriction device is designed as a flow barrier disk or as a preferably controllable or regulatable valve. In this case, the flow barrier disk is preferably elastic, the flow barrier disk being designed to be self-opening, so that when a delivery pressure or suction pressure is applied, glue passes through the locking disk while conveying the glue, while when the conveying pressure is switched off, the locking disk automatically allows glue to pass through or exit the locking disk prevented. For this purpose, for example, the flow barrier disk is designed as an elastic disk with one or more slots. A flow of the glue in the supply lines, ie in the supply line and in the discharge line, can also be achieved by a switchable or adjustable valve, so that the valve is or is closed before the gluing apparatus is removed, so that no glue is conveyed in the supply lines , whereby no glue emerges from the housing or the lines at the point of separation of the supply line or the supply line and the discharge line.
Des Weiteren ist in einer bevorzugten Ausführungsform vorgesehen, dass die Zuführleitung und/oder die Abführleitung jeweils wenigstens eine, vorzugsweise am Gehäuse des Leimauftragungsorgans angeordneten, Leitungskupplung bzw. Verbindungsstutzen aufweist, wobei vorzugsweise die Fließsperreinrichtung im Bereich der Leitungskupplung oder in der Leitungskupplung ausgebildet ist. Beispielsweise verfügt das Gehäuse des Leimauftragungsorgans über Verbindungsstutzen, die mit der Zuführleitung und/oder der Abführleitung gekoppelt werden, wobei die Fließsperreinrichtung beispielsweise in Form eines Ventils ausgebildet ist, wobei das Ventil bei Abziehen des Beleimungsapparates von der Maschine geschlossen wird und beim Einsetzen an der Maschine und Verbindung mit der Zuführleitung und/oder der Abführleitung geöffnet wird oder ist.Furthermore, it is provided in a preferred embodiment that the supply line and / or the discharge line each have at least one line coupling or connecting piece, preferably arranged on the housing of the glue application element, the flow blocking device preferably being formed in the area of the line coupling or in the line coupling. For example, the housing of the glue applicator has connecting stubs that are coupled to the supply line and / or the discharge line, the flow stop device being designed, for example, in the form of a valve, the valve being closed when the gluing apparatus is removed from the machine and when it is inserted on the machine and the connection to the supply line and / or the discharge line is or is open.
Bevorzugterweise weisen die Leitungskupplung der Zuführleitung und/oder die Leitungskupplung der Abführleitung jeweils einen, vorzugsweise am Gehäuse des Leimauftragungsorgans nach außen ragenden, Stutzen bzw. Verbindungsstutzen auf, so dass der Beleimungsapparat bzw. das Gehäuse des Beleimungsapparates bei der Montage an der Maschine auf einfache Weise mit den Leimversorgungsleitungen verbunden bzw. gekoppelt wird oder ist. Entsprechend ist auch bei der Demontage des Beleimungsapparates von der Maschine ein sicheres Entkoppeln von den Leimversorgungsleitungen möglich.The line coupling of the supply line and / or the line coupling of the discharge line preferably each have a nozzle or connection piece, preferably protruding outward on the housing of the glue application member, so that the gluing apparatus or the housing of the gluing apparatus can be easily installed on the machine is or is connected or coupled to the glue supply lines. Correspondingly, safe decoupling from the glue supply lines is also possible when dismantling the gluing apparatus from the machine.
In einer Ausgestaltung weisen die Stutzen bzw. die Verbindungsstutzen am Gehäuse entsprechende Fließsperreinrichtungen auf, um ein Heraustropfen oder ein ungewolltes Austreten von Leim aus den Stutzen, beispielsweise während der Demontage, zu verhindern.In one embodiment, the nozzles or the connecting nozzles on the housing have corresponding flow-blocking devices in order to prevent glue from dripping out or inadvertently escaping from the nozzles, for example during dismantling.
Überdies ist es günstig, wenn die Fließsperreinrichtung als in oder an der Zuführleitung angeordnete Unterdruckquelle ausgebildet ist, so dass Leim in der Zuführleitung entgegen der in der Zuführleitung vorgesehenen Fließrichtung des Leims gefördert wird oder förderbar ist, oder wenn die Fließsperreinrichtung als in oder an der Abführleitung angeordnete Unterdruckquelle ausgebildet ist, so dass Leim in der Abführleitung in die in der Abführleitung vorgesehenen Fließrichtung des Leims, vorzugsweise bei unterbrochener oder angehaltener Leimzufuhr in der Zuführleitung, gefördert wird oder förderbar ist.In addition, it is advantageous if the flow barrier device is designed as a vacuum source arranged in or on the supply line, so that glue is conveyed or can be conveyed in the supply line against the direction of flow of the glue provided in the supply line, or if the flow barrier device is in or on the discharge line arranged vacuum source is formed so that glue is conveyed or can be conveyed in the discharge line in the direction of flow of the glue provided in the discharge line, preferably with an interrupted or stopped glue supply in the supply line.
Hierdurch ist es beispielsweise möglich, dass Leim von der Kupplungsstelle in der Zuführleitung bzw. in der Abführleitung zurückgezogen wird, wodurch entsprechend eine Fließsperreinrichtung ausgebildet ist. Durch ein mit Unterdruck bewegtes Zurückziehen des Leims an der Kontaktstelle der Kupplung bzw. an der Verbindungsstelle wird ein Heraustropfen des Leims ebenfalls verhindert.This makes it possible, for example, for glue to be withdrawn from the coupling point in the supply line or in the discharge line, whereby a flow barrier device is formed accordingly. By pulling back the glue at the contact point of the coupling or at the connection point, moving with negative pressure, the glue is also prevented from dripping out.
Ferner ist bei einem Verfahren zum Betreiben einer Einrichtung zum Auftragen von Leim auf einen Materialstreifen der Tabak verarbeitenden Industrie mit einem in einem Gehäuse angeordneten Leimauftragungsorgan, insbesondere Rasterwalze, wobei mittels einer mit dem Gehäuse verbundenen Zuführleitung Leim zum Gehäuse oder Leimauftragungsorgan gefördert wird und/oder wobei mittels einer mit dem Gehäuse verbundenen Abführleitung Leim aus dem Gehäuse abgefördert wird, wobei das Gehäuse mit der Zuführleitung und/oder der Abführleitung lösbar koppelbar ist, vorgesehen, dass vor Entkopplung des Gehäuses mit der Zuführleitung Leim aus der Zuführleitung und/oder aus dem Gehäuse mittels einer Unterdruckquelle abgesaugt wird und/oder vor Entkopplung des Gehäuses mit der Abführleitung Leim aus der Abführleitung und dem Gehäuse entfernt wird.Furthermore, in a method for operating a device for applying glue to a strip of material in the tobacco processing industry with a glue application element arranged in a housing, in particular an anilox roller, glue being conveyed to the housing or glue application element by means of a feed line connected to the housing and / or wherein glue is conveyed out of the housing by means of a discharge line connected to the housing, the housing being releasably connectable to the feed line and / or the discharge line, it is provided that before decoupling the housing with the feed line glue from the feed line and / or from the housing by means of a vacuum source is sucked off and / or glue is removed from the discharge line and the housing before the housing is decoupled from the discharge line.
Hierbei ist vorgesehen, dass vor einer Demontage des Beleimungsapparates von einer Maschine bzw. vor einer Entfernung des Gehäuses des Leimauftragungsorgans oder der Beleimungsvorrichtung Leim aus dem Gehäuse und Leim in der Zuführleitung bzw. in der Abführleitung aus diesen wenigstens teilweise entfernt wird, so dass nach der Entfernung bzw. dem Absaugen des Leims aus den Leitungen und/oder dem Gehäuse während der Demontage des Beleimungsapparates kein Leim aus den entsprechenden Einrichtungen und den Verbindungsstellen heraustropft, wodurch eine saubere Entnahme des Beleimungsapparates möglich wird.It is provided that before dismantling the gluing apparatus from a machine or before removing the housing of the glue applicator or the gluing device, glue from the housing and glue in the supply line or in the discharge line is at least partially removed, so that after the Removal or suction of the glue from the lines and / or the housing during the dismantling of the gluing apparatus, no glue drips out of the corresponding devices and the connection points, whereby a clean removal of the gluing apparatus is possible.
Darüber hinaus ist es zusätzlich oder alternativ in einer Ausgestaltung des Verfahrens möglich, dass nach Kopplung des Gehäuses des Beleimungsapparates mit der Abführleitung die Abführleitung und das Gehäuse mit Leim, insbesondere vor dem Auftrag von Leim auf einen Materialstreifen, befüllt werden. Dadurch, dass eine leere Abführleitung und ein leeres Gehäuse vor der Inbetriebnahme der Maschine bzw. der Beleimung eines Materialstreifens der Tabak verarbeitenden Industrie Leim in die Abführleitungen und das Gehäuse eingebracht wird, wird nach Inbetriebnahme der Maschine bzw. des Beleimungsapparates erreicht, dass sich wenig oder keine Luft in dem Leim, der aus dem Gehäuse über die Abführleitung abgeleitet wird, befindet.Furthermore, in one embodiment of the method it is additionally or alternatively possible that after coupling the housing of the gluing apparatus to the discharge line, the discharge line and the housing are filled with glue, in particular before glue is applied to a strip of material. The fact that an empty discharge line and an empty housing is introduced into the discharge lines and the housing before the machine or the gluing of a strip of material of the tobacco processing industry glue is put into operation means that after the machine or the gluing apparatus has been put into operation, little or no there is no air in the glue that is discharged from the housing via the discharge line.
Weiterhin ist bei einer Einrichtung zum Auftragen von Leim auf einen Materialstreifen der Tabak verarbeitenden Industrie mit einem in einem Gehäuse angeordneten Leimauftragungsorgan, insbesondere Rasterwalze, wobei mittels einer mit dem Gehäuse verbundenen Zuführleitung Leim zum Leimauftragungsorgan gefördert wird oder ist und/oder wobei mittels einer mit dem Gehäuse verbundenen Abführleitung Leim aus dem Gehäuse abgefördert wird oder ist, vorgesehen, dass in der Zuführleitung zum Gehäuse zwischen einer ersten Förderpumpe bzw. Druckpumpe und dem Gehäuse zwei, insbesondere steuerbare, Ventile, vorzugsweise vor dem Eingang zum Gehäuse, vorgesehen sind und in der Abführleitung zwischen dem Gehäuse und einer zweiten Förderpumpe bzw. Saugpumpe zwei, insbesondere steuerbare, Ventile vorgesehen sind.Furthermore, in a device for applying glue to a strip of material of the tobacco processing industry with a glue application element arranged in a housing, in particular an anilox roller, glue is or is conveyed to the glue application element by means of a supply line connected to the housing and / or wherein by means of a Housing connected discharge line glue is or is removed from the housing, provided that two, in particular controllable, valves are provided in the supply line to the housing between a first feed pump or pressure pump and the housing, preferably in front of the inlet to the housing, and two, in the discharge line between the housing and a second feed pump or suction pump, in particular controllable valves are provided.
Durch die Verwendung von wenigstens zwei schaltbaren Ventilen in der Zuführleitung und in der Abführleitung wird einerseits ein sicherer Betrieb eines Beleimungsapparates während der Produktion von Produkten an einer Maschine der Tabak verarbeitenden Industrie erreicht, da zuverlässig bei Schaltung der Ventile in Durchlassrichtung Leim über die Zuführleitung mittels der Druckpumpe gefördert wird und gleichzeitig aus der Abführleitung über die in Durchlassstellung geschalteten Ventile und einer ausgangsseitig der zweiten angeordneten Saugpumpe Leim aus dem Gehäuse abgesaugt wird. Darüber hinaus wird eine tropffreie Entnahme bzw. Demontage des Beleimungsapparates von der Maschine erreicht, wenn die vier Ventile in Sperrstellung geschaltet sind, so dass ein Heraustropfen oder ein Nachlaufen von Leim in der Zuführleitung bzw. in der Abführleitung vermieden wird.By using at least two switchable valves in the supply line and in the discharge line, on the one hand, a reliable operation of a gluing apparatus is achieved during the production of products on a machine in the tobacco processing industry, since glue is reliably used when the valves are switched in the flow direction via the supply line Pressure pump is conveyed and at the same time glue is sucked out of the housing from the discharge line via the valves switched in the open position and an output side of the second suction pump. In addition, a drip-free removal or dismantling of the gluing apparatus from the machine is achieved when the four valves are switched to the blocking position, so that a dripping out or an overflow of glue in the supply line or in the discharge line is avoided.
Darüber hinaus ist es in einer weiteren Ausgestaltung der Einrichtung möglich, dass zwischen zwei Ventilen der Zuführleitung und zwischen zwei Ventilen der Abführleitung eine Verbindungsleitung zwischen der Zuführleitung und der Abführleitung vorgesehen ist, wodurch eine Art Bypassleitung zwischen der Zuführleitung und der Abführleitung erreicht wird.In addition, in a further embodiment of the device it is possible that a connecting line is provided between the supply line and the discharge line between two valves of the supply line and between two valves of the discharge line, whereby a type of bypass line is achieved between the supply line and the discharge line.
Es ist weiterhin vorteilhafterweise vorgesehen, dass in der Verbindungsleitung zwischen den zwei Ventilen der Zuführleitung und zwischen den zwei Ventilen der Abführleitung in der Verbindungsleitung ein, insbesondere steuerbares, Ventil angeordnet ist. Dadurch ist es möglich, dass durch entsprechende Schaltung der Ventile in der Zuführleitung und der Abführleitung sowie in der dazwischen angeordneten Verbindungsleitung über die bereits vorhandene Druckpumpe und die ebenfalls vorhandene Saugpumpe nach Einsetzen des Beleimungsapparates an der entsprechenden Stelle der Maschine der Tabak verarbeitenden Industrie ein Teil der Abführleitung und nach der Montage des Beleimungsapparates befüllt wird, wobei in diesem Fall das erste am Gehäuse ausgangsseitige Ventil der Abführleitung in Durchlassstellung geschaltet ist, während das zweite Ventil der Abführleitung in Sperrstellung ist, so dass Leim von der Druckpumpe über das erste ausgangsseitige Ventil der Zuführleitung und über das in Durchlassstellung sich befindende Ventil der Verbindungsleitung zur Abförderleitung gefördert wird, wobei das erste ausgangsseitige Ventil in der Abführleitung ebenfalls in Durchlassstellung ist, während das eingangsseitige Ventil am Gehäuse zur Saugpumpe in Sperrstellung sich befindet. Nach der Platzierung des Beleimungsapparates an der Maschine werden die Ventile in der Zuführleitung und der Abführleitung in Durchlassstellung geschaltet, während das Ventil in der Verbindungsleitung zwischen der Zuführleitung und der Abführleitung in Sperrstellung sich befinden. Zur Ausbildung eines Leimkreislaufes ist dabei die Druckpumpe im Zuführkreis und die Saugpumpe im Abführkreis mit einem gemeinsamen Leimvorrat verbunden, so dass von der Druckpumpe Leim aus dem Leimvorrat gefördert wird, während die Saugpumpe über die Abführleitung den aus dem Gehäuse des Leimauftragungsorgan entfernten Leim dem Leimvorrat zuführt.It is also advantageously provided that in the connecting line between the two valves of the supply line and between the two valves of the discharge line in the connecting line a, in particular controllable, valve is arranged. This makes it possible, by switching the valves in the supply line and the discharge line as well as in the connecting line between them via the already existing pressure pump and the suction pump, which is also present, to part of the tobacco processing industry after the gluing apparatus has been inserted at the corresponding point on the machine Drainage line and is filled after assembly of the gluing apparatus, in which case the first valve on the outlet side of the drainage line on the housing is switched to the open position, while the second valve of the drainage line is in the blocking position, so that glue from the pressure pump via the first output-side valve of the supply line and is conveyed via the valve in the open position of the connecting line to the discharge line, the first outlet-side valve in the discharge line also being in the open position, while the inlet-side valve on the housing to the suction pump in S. is locked. After the gluing apparatus has been placed on the machine, the valves in the supply line and the discharge line are switched to the open position, while the valve in the connecting line between the supply line and the discharge line is in the blocking position. To form a glue circuit, the pressure pump in the supply circuit and the suction pump in the discharge circuit are connected to a common glue supply, so that the pressure pump delivers glue from the glue supply, while the suction pump feeds the glue removed from the housing of the glue application unit to the glue supply via the discharge line .
Zur Entnahme des Beleimungsapparates mit dem Gehäuse wird das an der Druckpumpe erste ausgangsseitige Ventil in Sperrstellung geschaltet, während das zweite Ventil in Durchlassstellung ist. Ferner ist im Abführleitungskreis das am Gehäuse ausgangsseitige erste Ventil in Sperrstellung, während in der Abführleitung das zweite Ventil an der Eingangsseite der Saugpumpe angeordnete Ventil in Durchlassstellung ist, wobei das in der Verbindungsleitung zwischen der Zuführleitung und der Abführleitung angeordnete Ventil ebenfalls in Durchlassstellung ist, so dass vor der Entnahme des Beleimungsapparates Leim aus der Zuführleitung und dem Beleimungsapparat durch Anlegen eines Unterdrucks über die Saugpumpe abgeführt wird.To remove the gluing apparatus with the housing, the first outlet-side valve on the pressure pump is switched to the blocking position, while the second valve is in the open position. Further In the discharge line circuit, the first valve on the outlet side of the housing is in the blocking position, while in the discharge line the second valve arranged on the input side of the suction pump is in the open position, the valve arranged in the connecting line between the supply line and the discharge line also being in the open position, so that Before removing the gluing apparatus, glue is removed from the supply line and the gluing apparatus by applying a negative pressure via the suction pump.
Bei der Entnahme bzw. Demontage des Beleimungsapparates von der Produktionsmaschine der Tabak verarbeitenden Industrie, beispielsweise Filteransetzmaschine, befinden sich die Ventile der Zuführleitung und das Ventil in der Verbindungsleitung in Sperrstellung, während bei eingeschalteter Saugpumpe die Ventile an der Abführleitung in Durchlassstellung sind, so dass Leim aus dem Gehäuse des Beleimungsapparates abgepumpt wird. Dies erfolgt bevorzugterweise für eine vorbestimmte Zeit, um eine vorbestimmte Leimmenge aus dem Gehäuse des Beleimungsapparates zu entnehmen. Zur Entnahme befinden sich alle Ventile in Sperrstellung, wobei in diesem Fall beide Pumpen, d.h. sowohl Druckpumpe als auch Saugpumpe, ausgeschaltet sind.When removing or dismantling the gluing apparatus from the production machine of the tobacco processing industry, for example a filter attachment machine, the valves of the supply line and the valve in the connecting line are in the blocking position, while when the suction pump is switched on, the valves on the discharge line are in the open position, so that glue is pumped out of the housing of the gluing apparatus. This is preferably done for a predetermined time in order to remove a predetermined amount of glue from the housing of the gluing apparatus. All valves are in the blocking position for removal, in which case both pumps, i.e. both pressure pump and suction pump, are switched off.
Überdies wird ein geschlossener Leimkreislauf an einer Maschine dadurch ausgebildet, dass die Druckpumpe bzw. die erste Förderpumpe eingangsseitig mit einem Leimvorrat und/oder die Saugpumpe bzw. zweite Förderpumpe ausgangsseitig mit einem Leimvorrat verbunden sind, wobei insbesondere bevorzugterweise die Druckpumpe und die Saugpumpe mit demselben Leimvorrat verbunden sind.In addition, a closed glue circuit is formed on a machine in that the pressure pump or the first feed pump is connected on the input side to a glue store and / or the suction pump or second feed pump is connected to a glue store on the output side, the pressure pump and the suction pump being particularly preferably connected to the same glue store are connected.
Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1 und weitergebildet durch eine Einrichtung zum Auftragen von Leim auf einen Materialstreifen der Tabak verarbeitenden Industrie mit einem in einem Gehäuse angeordneten Leimauftragungsorgan, insbesondere Rasterwalze, wobei mittels einer mit dem Gehäuse verbundenen Zuführleitung Leim zum Gehäuse oder Leimauftragungsorgan gefördert wird oder ist und/oder wobei mittels einer mit dem Gehäuse verbundenen Abführleitung Leim aus dem Gehäuse abgefördert wird oder ist, wobei die Abführleitung mit einem Leimvorrat verbunden ist, wobei die Abführleitung mit einer, vorzugsweise in dem Leimvorrat angeordneten, Luftabscheideeinrichtung ausgebildet ist, um im abgeförderten Leim enthaltene Luftbläschen aus dem Leim abzuscheiden, die dadurch weitergebildet wird, dass die Luftabscheideeinrichtung als Steigrohr im Leimvorrat angeordnet ist, so dass der in der Abführleitung zurückfließende Leim durch ein Steigrohr in den Leimvorrat eingeleitet wird. Durch die Verwendung einer Luftabscheideeinrichtung im ausgebildeten Leimkreislauf für den Beleimungsapparat wird auf zuverlässige Weise Luft aus dem Leim entfernt, wobei bevorzugterweise die Abscheidung der Luft in Folge von Schwerkraft erfolgt.The object is achieved by the features of claim 1 and further developed by a device for applying Glue on a strip of material in the tobacco processing industry with a glue application element arranged in a housing, in particular an anilox roller, whereby glue is or is conveyed to the housing or glue application element by means of a feed line connected to the housing and / or where glue is removed from the housing by means of a discharge line connected to the housing Housing is or is conveyed away, wherein the discharge line is connected to a glue supply, wherein the discharge line is designed with an air separation device, preferably arranged in the glue supply, in order to separate air bubbles contained in the discharged glue from the glue, which is further developed by the air separation device is arranged as a riser pipe in the glue supply, so that the glue flowing back in the discharge line is introduced into the glue supply through a riser pipe. The use of an air separation device in the glue circuit formed for the gluing apparatus removes air from the glue in a reliable manner, the air being preferably separated out as a result of gravity.
Ferner wird die Einrichtung vorteilhafterweise dadurch weitergebildet, dass im unteren Bereich des Steigrohrs und im Bereich der Verbindung der Abführleitung mit dem Leimvorrat eine Leimentnahmestelle außerhalb des Steigrohrs vorgesehen ist, die mit der Zuführleitung zum Zuführen von Leim zum Leimauftragungsorgan verbunden ist. Dadurch ist es möglich, dass an einer Öffnung des Leimvorrates rückgeführter Leim über die Abführleitung in den Leimvorrat eingebracht wird und gleichzeitig unter Verwendung des Steigrohrs die Luft oder Luftbläschen im zurückgeführten Leim abgeschieden werden, wobei zudem an derselben Kontaktstelle mit dem Leimvorrat bzw. an der Öffnung ebenfalls eine Entnahmestelle vorgesehen ist, wobei der zu entnehmende Leim im unteren Bereich des Steigrohrs entnommen wird.Furthermore, the device is advantageously developed in that in the lower area of the riser pipe and in the area of the connection between the discharge line and the glue supply a glue take-off point is provided outside the riser pipe, which is connected to the feed line for feeding glue to the glue application element. This makes it possible for glue that is returned to an opening in the glue supply to be introduced into the glue supply via the discharge line and, at the same time, using the riser pipe to separate out the air or air bubbles in the returned glue, and at the same point of contact with the glue supply or at the opening a removal point is also provided, the glue to be removed being removed in the lower region of the riser pipe.
Außerdem ist ein Gehäuse eines Leimauftragungsorgans, der Tabak verarbeitenden Industrie mit einem im Gehäuse angeordneten Leimauftragungsorgan, insbesondere Rasterwalze, vorgesehen, wobei an der Außenseite des Gehäuses eine Verbindungskupplung zum Verbinden einer Zuführleitung zum Zuführen von Leim in das Gehäuse vorgesehen ist, wobei unterhalb der Verbindungskupplung ein Auffangbehälter angeordnet ist und/oder an der Außenseite des Gehäuses eine Verbindungskupplung zum Verbinden einer Abführleitung zum Abführen von Leim aus dem Gehäuse vorgesehen ist, wobei unterhalb der Verbindungskupplung ein Auffangbehälter angeordnet ist. Durch die Verwendung von Auffangbehältern unterhalb der Verbindungskupplungen wird ein zuverlässiger Tropfschutz bei der Entnahme eines Beleimungsapparates am Gehäuse des Apparates erreicht.In addition, a housing of a glue application device of the tobacco processing industry with a glue application device arranged in the housing, in particular an anilox roller, is provided, with a connection coupling for connecting a feed line for feeding glue into the housing being provided on the outside of the housing, with a coupling below the connection coupling A collecting container is arranged and / or a connection coupling is provided on the outside of the housing for connecting a discharge line for discharging glue from the housing, a collecting container being arranged below the connection coupling. By using collecting containers below the connection couplings, a reliable drip protection is achieved when removing a gluing device from the housing of the device.
Ferner ist bei einem Gehäuse des Leimauftragungsorgans der Tabak verarbeitenden Industrie mit einem im Gehäuse angeordneten Leimauftragungsorgan, insbesondere Rasterwalze, ein Sensor oberhalb des Gehäusebodens vorgesehen ist, wobei mittels des Sensors auf berührungslose Weise das Niveau von Leim im Gehäuse erfasst wird. Dadurch, dass das Leimniveau über dem Gehäuseboden auf berührungslose Weise ermittelt wird, wird während des Betriebs eines Leimauftragungsorgans an einer Maschine der Tabak verarbeitenden Industrie das Niveau zuverlässig und direkt überwacht, da der Sensor auf die freie Oberfläche des Leims gerichtet ist, so dass das Leimniveau im Gehäuse nicht seitlich an den Wandflächen des Gehäuses überwacht wird, wodurch aufgrund der Adhäsion des zähflüssigen Leims keine zuverlässige Niveaumessung möglich ist.Furthermore, a sensor is provided above the bottom of the housing in a housing of the glue application element of the tobacco processing industry with a glue application element arranged in the housing, in particular an anilox roller, the level of glue in the housing being detected in a contactless manner by means of the sensor. Because the glue level above the housing base is determined in a contactless manner, the level is reliably and directly monitored during the operation of a glue applicator on a machine in the tobacco processing industry, since the sensor is aimed at the free surface of the glue, so that the glue level in the housing is not monitored on the side of the wall surfaces of the housing, which means that no reliable level measurement is possible due to the adhesion of the viscous glue.
Dazu ist weiter vorgesehen, dass der Sensor als Ultraschallsensor ausgebildet ist, wobei mittels des Sensors ein erzeugtes Ultraschallmesssignal von oben, vorzugsweise vertikal, auf die freie Oberfläche des Leims im Gehäuse bzw. über dem Gehäuseboden gerichtet ist oder wird.For this purpose, it is also provided that the sensor is an ultrasonic sensor is formed, wherein by means of the sensor an ultrasonic measurement signal generated is directed from above, preferably vertically, onto the free surface of the glue in the housing or above the housing base.
Dazu wird gemäß einer vorteilhaften Ausgestaltung vorgeschlagen, dass ein Leitkanal am Ultraschallsensor angeordnet ist, so dass das Ultraschallmesssignal im Leitkanal zu einer Austrittsseite des Leitkanals geführt wird oder ist, wobei an der Austrittsseite das Ultraschallmesssignal von oben, insbesondere vertikal, auf die Oberfläche des Leims bzw. den Boden des Gehäuses gerichtet ist oder wird. Dabei kann der Leitkanal mit dem Sensor, vorzugsweise lösbar, an der Einkoppelseite des Ultraschallmesssignals verbunden sein. Die Position des Sensors kann hierbei beliebig gewählt werden; entscheidend ist, dass das an der Austrittsseite des Leitkanals austretende Ultraschallmesssignal oberhalb des Leims im Gehäuse bzw. über dem Gehäuseboden vertikal nach unten gerichtet ist.For this purpose, it is proposed according to an advantageous embodiment that a guide channel is arranged on the ultrasonic sensor so that the ultrasonic measurement signal in the guide channel is or is guided to an exit side of the guide channel, with the ultrasonic measurement signal from above, in particular vertically, onto the surface of the glue or on the exit side the bottom of the housing is or will be directed. The guide channel can be connected to the sensor, preferably releasably, on the coupling side of the ultrasonic measurement signal. The position of the sensor can be chosen arbitrarily; The decisive factor is that the ultrasonic measurement signal emerging on the outlet side of the guide channel is directed vertically downwards above the glue in the housing or above the housing base.
Außerdem ist weiterhin vorgesehen, dass der Sensor an der Gehäuseoberseite entsprechend angeordnet ist.It is also provided that the sensor is arranged accordingly on the top of the housing.
Ferner ist vorgesehen, dass mittels einer mit dem Gehäuse verbundenen Zuführleitung Leim zum Gehäuse oder Leimauftragungsorgan gefördert wird oder ist.It is further provided that glue is or is conveyed to the housing or glue application member by means of a supply line connected to the housing.
Ferner wird die Aufgabe gelöst durch eine Maschine der Tabak verarbeitenden Industrie, insbesondere Filteransetzmaschine, die mit einer voranstehend beschriebenen Einrichtung zum Auftragen von Leim auf einen Materialstreifen der Tabak verarbeitenden Industrie, wobei zur Vermeidung von Wiederholungen auf die voranstehenden Ausführungen ausdrücklich verwiesen wird.Furthermore, the object is achieved by a machine of the tobacco processing industry, in particular a filter attachment machine, which is equipped with an above-described device for applying glue to a strip of material in the tobacco processing industry, reference being expressly made to the above statements to avoid repetition.
