Description

Die Erfindung betrifft eine Vorrichtung zum Auftragen von Leim auf Bereiche von Papier- oder Kunststoffbahnen oder von Papier- oder Kunststoffbahnabschnitten zur Herstellung von Säcken, vorzugsweise von Papiersäcken, nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Reinigen einer solchen Vorrichtung nach dem Oberbegriff des Anspruchs 6.The invention relates to a device for applying glue to areas of paper or plastic webs or paper or plastic web sections for the production of sacks, preferably of paper sacks, according to the preamble of claim 1 and a method for cleaning such a device according to the preamble of the claim 6th

Eine eingangs erwähnte Vorrichtung ist in der Anmeldung DE 103 09 893 ausführlich beschrieben. Bei der Herstellung von Papiersäcken müssen verschiedene Bestandteile mit Klebstoff versehen werden. Zunächst wird aus einer Bahn oder mehreren Bahnen, die zunächst eine - oft mehrlagige - Bahn bilden, ein Schlauch gebildet, wobei in Längsrichtung eine oder mehrere Leimspuren auf die Bereiche der Bahn aufgetragen werden, die anschließend mit anderen Bereichen der Bahn überlappt werden (so genannte Schlauchbildung). Die Bahnen können aus Papier und/oder Kunststoff bestehen. Aus dem gebildeten Schlauch werden Schlauchstücke vereinzelt, an die später Böden angeformt werden, wobei zur Verklebung der Böden wiederum Klebstoff auf Teile dieser Schlauchstücke aufzutragen ist. Als Klebstoff wird häufig Stärkeleim verwendet. In den folgenden Teilen dieser Anmeldung wird daher anstelle des Wortes Klebstoff auch das Wort Leim verwendet, ohne dass dabei der Gegenstand der Erfindung eingeschränkt ist.An initially mentioned device is in the application DE 103 09 893 described in detail. In the manufacture of paper bags, various components must be provided with adhesive. First, a tube is formed from one or more webs which initially form a web, often multi-ply, wherein one or more glue tracks are applied in the longitudinal direction to the regions of the web which are subsequently overlapped with other regions of the web (so-called webs) tube formation). The webs may be made of paper and / or plastic. From the tube formed pieces of tubing are isolated, are molded to the later soils, in turn, for the bonding of the floors adhesive is applied to parts of these pieces of hose. As an adhesive, starch glue is often used. In the following parts of this application, therefore, instead of the word adhesive, the word glue is also used without limiting the subject matter of the invention.

In der DE 103 09 893 wird nun vorgeschlagen, anstelle von seit Jahrzehnten verwendeten Klebstoffauftragswalzen, die formatabhängige Klischees tragen, Vorrichtungen zu verwenden, die das formatmäßige Auftragen des Klebstoffs mittels Leimventile durchführen. Durch zeitlich passendes Ansteuern einzelner Ventile kann das aufgetragene Format beeinflusst werden. Solche Vorrichtungen umfassen oft eine Düseneinheit mit mehreren Leimaustrittsöffnungen und Leimzuführleitungen zu diesen Leimaustrittsöffnungen. Weiterhin sind die Leimventile an dieser Düseneinheit angeordnet, über die die Leimzuführleitungen und damit die Leimaustrittsöffnungen selektiv mit Leim versorgbar sind. Die Düseneinheit umfasst zudem zumindest eine Leimkammer, mit der der Leim bereitstellbar ist. Über weitere Leimleitungen ist der Leim aus der Leimkammer an die einzelnen Leimventile heranführbar. Die Düseneinheit ist oft zweiteilig aufgebaut, wobei in einer Düsenplatte in der Regel die Leimaustrittsöffnungen und Leimzuführleitungen eingebracht sind. Der Düsenkopf trägt oft die Leimventile sowie die Leimkammer.In the DE 103 09 893 It is now proposed to use, instead of adhesive applicator rollers used for decades, the format-dependent clichés, devices that format the application of the adhesive by means of glue valves. By timed control of individual valves, the applied format can be influenced. Such devices often include a nozzle assembly having a plurality of glue exit ports and glue delivery lines to these glue exit ports. Furthermore, the glue valves are arranged on this nozzle unit, via which the glue supply lines and thus the glue outlet openings can be selectively supplied with glue. The nozzle unit also comprises at least one glue chamber, with which the glue can be provided. Via additional glue lines, the glue from the glue chamber can be brought to the individual glue valves. The nozzle unit is often constructed in two parts, wherein in a nozzle plate usually the glue outlet openings and Leimzuführleitungen are introduced. The nozzle head often carries the glue valves as well as the glue chamber.

Eine der in der DE 103 09 893 offenbarte Einrichtung ähnliche Vorrichtung kann auch zum Erzeugen der Leimspuren vor der Schlauchbildung verwendet werden.One of the in the DE 103 09 893 The device similar to that disclosed may also be used to produce the glue streaks prior to tube formation.

Da der sowieso schon sehr zähflüssige Leim eintrocknen kann, ist eine rechtzeitige Reinigung der Leim führenden Komponenten, insbesondere der Leimventile, unabdingbar. Daher umfasst die genannte Vorrichtung einen Anschluss für ein Reinigungsfluid, wie beispielsweise Wasser. Wird das Format der zu produzierenden Säcke umgestellt, so muss die Vorrichtung vollständig gereinigt werden, um insbesondere die Ventile, die bei der folgenden Produktionscharge nicht benötigt werden, zu säubern, so dass sie funktionsfähig bleiben. Dazu wird das Reinigungsfluid in die Leimkammer eingeführt, so dass diese und die sich daran anschließenden Leim führenden Komponenten gespült werden können.Since the already very viscous glue can dry out, a timely cleaning of the glue-leading components, in particular of the glue valves, is indispensable. Therefore, said device comprises a connection for a cleaning fluid, such as water. If the format of the bags to be produced is changed, the device must be completely cleaned in order, in particular, to clean the valves, which are not needed in the following production batch, so that they remain functional. For this purpose, the cleaning fluid is introduced into the glue chamber, so that these and the adjoining glue leading components can be flushed.

Diese vollständige Reinigung ist jedoch zeitraubend und damit teuer, da in dieser Zeit keine Produktion erfolgen kann. Zudem ist die Reinigung von Ventilen, die im Anschluss wieder zum Leimauftrag verwendet werden, überflüssig.However, this complete cleaning is time-consuming and therefore expensive, since no production can take place during this time. In addition, the cleaning of valves, which are then used again for the glue application, superfluous.

Die Druckschrift US 2003/0080205 A1 zeigt eine Vorrichtung, bei der eine von der Leimkammer unabhängige Fluidkammer vorgesehen ist, mit welcher das Reinigungsfluid zuführbar ist. Der Anschluss für das Reinigungsfluid ist nun nicht mehr, wie aus dem Stand der Technik bekannt, an der Leimkammer, sondern an der Fluidkammer angeordnet. Damit ist es nun nicht mehr notwendig, die zum Teil erhebliche Leimmenge aus der Leimkammer zu entnehmen, um Teile der Leim führenden Teile zu reinigen. Bereits diese Möglichkeit führt dazu, dass das Reinigen einzelner Leim führender Teile schneller als im Stand der Technik erfolgt, so dass Zeit und damit Kosten einsparbar sind.The publication US 2003/0080205 A1 shows a device in which an independent of the glue chamber fluid chamber is provided, with which the cleaning fluid is supplied. The connection for the cleaning fluid is no longer, as known from the prior art, arranged on the glue chamber, but on the fluid chamber. Thus, it is no longer necessary to remove the sometimes considerable amount of glue from the glue chamber to clean parts of the glue leading parts. Already this possibility leads to the fact that the cleaning of individual glue of leading parts takes place faster than in the state of the art, so that time and thus costs can be saved.

Auch die Druckschriften EP 0 844 068 A2 und EP 2 163 312 A1 zeigen separate Fluidzuführleitungen.Also the pamphlets EP 0 844 068 A2 and EP 2 163 312 A1 show separate fluid supply lines.

Die Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung vorzuschlagen, mit der ein Eintritt von Leim in die Fluidleitungen und/oder die Fluidkammer verhinderbar ist..The object of the present invention is to propose a device with which an entry of glue into the fluid lines and / or the fluid chamber can be prevented.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Demnach beinhaltet jede Fluidleitung ein Rückschlagventil.The object is solved by the features of claim 1. Accordingly, each fluid line includes a check valve.

In einer besonders bevorzugten Ausgestaltung sind Fluidleitungen vorgesehen, welche in Leimleitungen oder in Leimzuführleitungen münden. Damit ist es möglich, das Reinigungsfluid von der Fluidkammer aus an die Leim führenden Teile heranzuführen, wobei dies insbesondere im Bereich der Ventile erfolgt. Um die Leim führenden Teile zu reinigen, wird die Leimkammer hydraulisch verschlossen und das Reinigungsfluid unter Druck gesetzt. Münden die Fluidleitungen in den Leimzuführleitungen, so können die auf diese Weise auf einfache und schnelle Weise alle Leimaustrittsöffnungen, also die Stellen des Leimleitungssystems, die mit der Außenluft in Kontakt treten, gereinigt werden. Stromaufwärts des Leimleitungssystems verbleibt der Leim in den Leim führenden Teile, jedoch gelangt keine Außenluft an den Leim, was zum Festtrocknen des Leims führen würde. Das Reinigen dieser recht kurzen Leim führenden Teile kann sehr schnell erfolgen. Es braucht keinerlei Leim entnommen werden.In a particularly preferred embodiment, fluid lines are provided, which open in glue lines or in Leimzuführleitungen. It is thus possible to introduce the cleaning fluid from the fluid chamber to the parts which carry the glue, this taking place in particular in the area of the valves. To clean the glue-carrying parts, the glue chamber is closed hydraulically and the cleaning fluid is pressurized. Münden the fluid lines in the glue supply, so the way in a simple and fast way all glue outlet openings, so the points of the Leimleitungssystems, which come into contact with the outside air, are cleaned. Upstream of the glue line system, the glue remains in the glue-carrying parts, but no outside air gets to the glue, which would lead to solid-drying of the glue. Cleaning this very short glue leading parts can be done very quickly. It needs no glue to be taken.

Münden die Fluidleitungen jedoch in die Leimleitungen und wird dann das Reinigungsfluid unter Druck gesetzt, so werden die Ventile und die diesem Ventil zugehörigen Leim führenden Teile gereinigt, die geöffnet sind. Es ist also ein Reinigen von Ventile möglich, die beispielsweise für einen folgenden Auftrag nicht benötigt werden. Eine solche Reinigung kann sogar dann erfolgen, wenn ein neuer Auftrag bereits begonnen wurde. Eine Produktionsunterbrechung zum Zwecke der Reinigung Leim führender Teile ist damit nicht mehr notwendig.However, the fluid lines in the glue lines and then the cleaning fluid is pressurized, the valves and the glue associated with this valve are cleaned leading parts that are open. So it is possible to clean valves that are not needed, for example, for a subsequent order. Such cleaning can be done even if a new job has already been started. A production interruption for the purpose of cleaning glue leading parts is therefore no longer necessary.

In einer weiteren bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass jedem Leimventil zumindest eine Fluidleitung zugeordnet ist, wobei die Fluidleitung in der das Ventil mit Leim versorgenden Leimleitung mündet. Alternativ kann die Fluidleitung in der Leimzuführleitung (zwischen Ventil und Leimaustrittsöffnung) münden. Unabhängig von der Anordnung der Mündung ist es wichtig, jedem Ventil eine Fluidleitung zuzuordnen, so dass ein selektives Reinigen eines einzelnen Ventils und/oder der jeweils diesem Ventil zugeordneten Leim führenden Leitungen möglich ist.In a further preferred embodiment of the invention it is provided that each glue valve is associated with at least one fluid line, wherein the fluid line opens in the glue line supplying the valve with glue. Alternatively, the fluid line in the Leimzuführleitung (between valve and Leimaustrittsöffnung) open. Regardless of the location of the orifice, it is important to associate a fluid line with each valve so that selective cleaning of a single valve and / or lines carrying the glue associated therewith is possible.

Gegenstand der Erfindung ist weiterhin ein Verfahren zum Reinigen einer erfindungsgemäßen Vorrichtung, wie sie oben beschrieben ist. Dabei wird das Reinigungsfluid mit einer von der Leimkammer unabhängigen Fluidkammer zugeführt. Dabei wird das Reinigungsfluid durch ein Rückschlagventil geführt.The invention further provides a method for cleaning a device according to the invention, as described above. In this case, the cleaning fluid is supplied with a separate from the glue chamber fluid chamber. The cleaning fluid is passed through a check valve.

In einer weiteren Ausführungsform des genannten Verfahrens ist vorgesehen, dass die Leimkammer gegen Zufluss von Reinigungsfluid hydraulisch geschlossen wird. Dadurch wird verhindert, dass das Reinigungsfluid im Mündungsbereich der Fluidleitung in die Leim führenden Leitungen stromaufwärts gelangt und das Fluid sich mit dem Leim vermischt.In a further embodiment of said method, it is provided that the glue chamber is hydraulically closed against inflow of cleaning fluid. This prevents the cleaning fluid in the mouth region of the fluid line from entering the glue-carrying lines upstream and the fluid mixing with the glue.

Vorteilhaft ist, dass einzelne Ventile, die gereinigt werden sollen, geöffnet werden. Dieses Öffnen erfolgt bevorzugt, wenn das Reinigungsfluid unter Druck gesetzt wird.It is advantageous that individual valves that are to be cleaned, are opened. This opening preferably occurs when the cleaning fluid is pressurized.

Weiterhin ist es vorteilhaft, wenn die Vorrichtung zum Auftragen von Leim vor dem Reinigen aus einer Betriebsposition, in der Leim auf Bereiche von Papier-oder Kunststoffbahnen oder Papier- oder Kunststoffbahnabschnitten zur Herstellung von Papiersäcken aufgetragen wird, in eine Reinigungsposition bewegt wird. In dieser Reinigungsposition kann insbesondere eine Einrichtung zum Auffangen und/oder Ableiten des Fluids und/oder des ausgespülten Leims vorgesehen sein, beispielsweise eine Auffangwanne.Furthermore, it is advantageous if the device for applying glue before cleaning is moved from an operating position, in which glue is applied to areas of paper or plastic webs or paper or plastic web sections for producing paper sacks, into a cleaning position. In this cleaning position, in particular a device for collecting and / or discharging the fluid and / or the flushed glue may be provided, for example a collecting trough.

In einer besonders bevorzugten Ausführungsform ist vorgesehen, das Reinigungsfluid mit einem Druck von mehr als 10 bar, vorzugsweise mehr als 20 bar beaufschlagt wird. Auf diese Weise kann eine zügige und insbesondere auch gründliche Reinigung erfolgen.In a particularly preferred embodiment, it is provided that the cleaning fluid is subjected to a pressure of more than 10 bar, preferably more than 20 bar. In this way, a quick and especially thorough cleaning can be done.

Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor.Further embodiments of the invention will become apparent from the description and the claims.

Es ist auch möglich, die Bahn über mehrere Führungswalzen zu führen und die Vorrichtung 1 zwischen zwei Walzen anzuordnen, so dass die Vorrichtung an einer Stelle auf die Bahn wirkt, an der sie frei geführt wird. In diesem Fall ist es einfacher, im Bereich der Bahn, insbesondere seitlich der Bahn, Auffangelemente anzuordnen, die das Fluid-/Leimgemisch während der Produktion auffangen.The device for applying glue 1 acts against a counter-pressure cylinder 3, via which a web 2 can be guided. The web 2 can be multi-layered. It is also possible to guide the web over a plurality of guide rollers and to arrange the device 1 between two rollers, so that the device acts at a location on the web, where it is guided freely. In this case, it is easier to arrange collecting elements in the area of the web, in particular laterally of the web, which collect the fluid / glue mixture during production.

Die Vorrichtung 1 umfasst eine Düseneinheit 4, die mehrere Bestandteile umfasst. Zunächst ist die Düsenplatte 5 zu nennen, die mehrere, über diese Düsenplatte verteilte Leimaustrittsöffnungen 6 umfasst, aus welchen Leim austreten und auf die Bahn 2 auftreffen kann. Die Verteilung der Leimaustrittsöffnungen 6 über die Düsenplatte kann den Erfordernissen entsprechend vorgesehen werden. In der angesprochenen Querklebung einer Schlauchmaschine können Leimaustrittsöffnungen einzeln nebeneinander quer zur Transportrichtung der Bahn 2 angeordnet sein.The device 1 comprises a nozzle unit 4 comprising a plurality of components. First mention should be made of the nozzle plate 5 which comprises a plurality of glue outlet openings 6 distributed over this nozzle plate, from which glue can emerge and strike the web 2. The distribution of the glue outlet openings 6 via the nozzle plate can be provided according to the requirements. In the mentioned transverse bonding of a hose machine, glue outlet openings can be arranged individually next to one another transversely to the transport direction of the web 2.

Die Düsenplatte 5 ist an einem Düsenkopf 7 befestigt, der aus einem oder mehreren Einzelteilen bestehen kann. Im gezeigten Beispiel ist ein Düsenkopf dargestellt, der aus den drei Teilen 7a, 7b und 7c besteht. Der Düsenkopf kann im nicht dargestellten Maschinengestell oder an daran befestigten Komponenten gelagert sein. Weiterhin sind an dem Düsenkopf 7 mehrere Leimventile 8 angeordnet, von denen jedoch nur eines dargestellt ist. Schließlich stehen mit dem Düsenkopf 7 noch ein oder mehrere als Leimkanäle 9 bezeichnete Leimkammern in Verbindung. Im gezeigten Ausführungsbeispiel ist hiervon nur ein Leimkanal 9 gezeigt, der als Bohrung in den Teil 7b des Düsenkopfes 7 eingebracht ist.The nozzle plate 5 is attached to a nozzle head 7, which may consist of one or more individual parts. In the example shown, a nozzle head is shown, which consists of the three parts 7a, 7b and 7c. The nozzle head may be mounted in the machine frame, not shown, or components attached thereto. Furthermore, a plurality of glue valves 8 are arranged on the nozzle head 7, but only one of which is shown. Finally, with the nozzle head 7 still one or more known as glue channels 9 glue chambers in combination. In the embodiment shown hereof only one glue channel 9 is shown, which is introduced as a bore in the part 7b of the nozzle head 7.

Der Leimfluss erfolgt nun wie folgt: Über einen nicht gezeigten Anschluss, der mittels Pumpen aus einem Leimreservoir gespeist wird, gelangt Leim in den Leimkanal 9. Hiervon zweigen Leimleitungen 10 ab, wobei jedem Leimventil 8 vorteilhafterweise zumindest eine eigene Leimleitung zugeordnet ist. Mit diesem Leimventil 8 ist der Leimstrom unterbrechbar und herstellbar. Bei geöffnetem Leimventil 8 strömt der Leim weiter durch die Leimzuführleitung 11, die sich durch das Bauteil 7a weiter bis zur Leimaustrittsöffnung 6 fortsetzt.The glue flow is now as follows: Via a connection, not shown, which is fed by means of pumps from a glue reservoir, glue passes into the glue channel 9. From this branch glue lines 10, wherein each glue valve 8 is advantageously associated with at least one own glue line. With this glue valve 8, the glue stream can be interrupted and produced. When the glue valve 8 is open, the glue continues to flow through the glue feed line 11, which continues through the component 7a to the glue outlet opening 6.

In die Leimleitung 10 mündet mit einer Mündung 14 eine Fluidleitung 12, die ihren Startpunkt in der Fluidkammer 13 findet. Diese Fluidkammer 13 ist im gezeigten Ausführungsbeispiel außerhalb des Düsenkopfes 7 angeordnet, kann aber, ähnlich wie der Leimkanal 9, in ihm integriert sein. die Fluidkammer 13 und der Leimkanal 9 sind vorteilhafterweise parallel zueinander angeordnet.In the glue line 10 opens with a mouth 14, a fluid line 12, which finds its starting point in the fluid chamber 13. This fluid chamber 13 is arranged in the embodiment shown outside of the nozzle head 7, but may, similar to the glue channel 9, be integrated in it. the fluid chamber 13 and the glue channel 9 are advantageously arranged parallel to one another.

Nahe der Mündung 14 ist in der Fluidleitung 12 ein Rückschlagventil 15 vorgesehen, welches sowohl ein Einströmen des Leims in die Fluidleitung 12 und in die Fluidkammer 13 als auch ein Zurückströmen des Reinigungsfluids, welches meist mit Leim vermischt ist, verhindert. Die Figur 5 zeigt Einzelheiten eines für die genannten Zwecke besonders bevorzugten Rückschlagventils.Near the mouth 14, a check valve 15 is provided in the fluid line 12, which prevents both an influx of the glue into the fluid line 12 and into the fluid chamber 13 and a backflow of the cleaning fluid, which is usually mixed with glue. The FIG. 5 shows details of a particularly preferred for the purposes purposes check valve.

Unterhalb der Düseneinheit 4 ist eine Auffangwanne 16 vorgesehen, die an einem geeigneten Bauteil befestigt ist und beispielsweise auf diese Weise mit dem nicht gezeigten Maschinengestell verbunden ist. Die Düseneinheit 4 kann um nicht gezeigte Lager geschwenkt werden, so dass die Leimaustrittsöffnungen oberhalb der Auffangwanne 16 positionierbar sind (so genannte Reinigungsposition), um etwa ein Auffangen des Fluid-/Leimgemisches während des Reinigungsvorgangs zu gewährleisten. In oder an der Auffangwanne 16 kann zudem ein Reinigungselement wie etwa ein Schwamm vorgesehen sein, mit dem sich an der Oberfläche der Düsenplatte 5 im Bereich der Leimaustrittsöffnung 6 ansammelnder Leim und/oder Reinigungsfluid abgestreift werden kann.Below the nozzle unit 4, a drip pan 16 is provided, which is attached to a suitable component and is connected for example in this way with the machine frame, not shown. The nozzle unit 4 can be pivoted about bearings, not shown, so that the glue outlet openings are positioned above the sump 16 (so-called cleaning position) to ensure about a collection of the fluid / glue mixture during the cleaning process. In addition, a cleaning element, such as a sponge, can be provided in or on the drip pan 16, with which the glue and / or cleaning fluid accumulating on the surface of the nozzle plate 5 in the area of the glue outlet opening 6 can be scraped off.

Die Figur 2 zeigt nun noch einmal die in Figur 1 gezeigte Anordnung der Leitungen 10, 11, 12, 14, Kammern 9, 13 und Ventile 8, 15 in schematischer Darstellung.The FIG. 2 shows again the in FIG. 1 shown arrangement of the lines 10, 11, 12, 14, chambers 9, 13 and valves 8, 15 in a schematic representation.

Die Figur 3 zeigt eine gegenüber der in der Figur 2 gezeigten Situation abgewandelte Anordnung der Funktionselemente 8- 15. Hier ist die Mündung 14 nicht in der Leimleitung 10, sondern in der Leimzuführleitung 11 angeordnet. Damit werden die zu reinigenden Leitungsabschnitte und damit die Reinigungszeit kurz gehalten.The FIG. 3 shows one opposite to the one in the FIG. 2 Here, the mouth 14 is not arranged in the glue line 10, but in the glue supply 11. Thus, the line sections to be cleaned and thus the cleaning time are kept short.

Die Figur 4 zeigte eine weitere schematische Darstellung einer erfindungsgemäßen Vorrichtung, mit der der bereits mehrfach verwendete Begriff "hydraulisch schließen" näher erläutert werden soll. Die bereits anhand der Figuren 1 bis 3 erläuterten Komponenten der Vorrichtung sind auch in der Figur 4 mit gleichen Bezugszeichen versehen worden. Zusätzlich finden sich in dieser Figur 4 eine Zulaufleitung 20 zur Leimkammer 9, in der ein weiteres Ventil 21 angeordnet ist. Selbstverständlich kann sich das Ventil auch direkt an der Leimkammer 9 befinden und von der Zulaufleitung 20 gespeist werden. Auf gleiche Weise ist in oder an der Zulaufleitung 22 zur Fluidkammer 13 ein Ventil 23 angeordnet.The FIG. 4 showed a further schematic representation of a device according to the invention, with which the already repeatedly used term "hydraulically close" to be explained in more detail. The already on the basis of FIGS. 1 to 3 explained components of the device are also in the FIG. 4 have been provided with the same reference numerals. In addition, you will find in this FIG. 4 a supply line 20 to the glue chamber 9, in which a further valve 21 is arranged. Of course, the valve can also be located directly on the glue chamber 9 and fed by the feed line 20. In the same way, a valve 23 is arranged in or on the feed line 22 to the fluid chamber 13.

Beide Ventile 21, 23 sind als Schaltventile ausgebildet, mit denen der Zufluss zu den Kammern 9, 13 herstellbar oder unterbrechbar ist. Im Produktionsbetrieb ist das Ventil 21 geöffnet und das Ventil 23 geschlossen, so dass der Leim der Leimkammer 9 zugeführt und von dort über die bereits beschriebenen Leitungen und Ventile zu Leimaustrittöffnungen 6 geführt wird. Der Leim dabei kann das Rückschlagventil 15 nicht passieren und gelangt daher nicht in die Fluidkammer 13.Both valves 21, 23 are designed as switching valves, with which the inflow to the chambers 9, 13 can be produced or interrupted. In production operation, the valve 21 is opened and the valve 23 is closed, so that the glue is fed to the glue chamber 9 and from there via the lines and valves already described to glue outlet openings 6. The glue thereby can not pass the check valve 15 and therefore does not reach the fluid chamber 13.

Soll nun jedoch ein bestimmtes Ventil 8 und die dazu gehörigen Leitungen 10 und 11 sowie zugehörige Leimaustrittsöffnung 6 gereinigt werden, so wird das Ventil 21 und alle nicht zu reinigenden Ventile 8 geschlossen oder geschlossen gehalten. Das oder die zu reinigenden Ventile 8 sowie das Ventil 23 werden nun geöffnet, so dass das Reinigungsfluid nun in die Leitung 12 bis zur Mündung 14 gelangt. Da der Weg in Richtung der Leimkammer 9 nun aufgrund der geschlossenen Ventile versperrt ist, drückt das Reinigungsfluid durch das Ventil 8 und die Leitung 11 zur Leimaustrittsöffnung und tritt dort aus, wobei es den in diesen Teilen befindlichen Leim herausdrückt. Der Weg in Richtung der Leimkammer 9, der für das Reinigungsfluid versperrt ist, wird dabei als "hydraulisch geschlossen" bezeichnet.However, if now a particular valve 8 and the associated lines 10 and 11 and associated glue outlet opening 6 are cleaned, the valve 21 and all not to be cleaned valves 8 is kept closed or closed. The one or more to be cleaned valves 8 and the valve 23 are now opened, so that the cleaning fluid is now in the line 12 to Mouth 14 arrives. Since the path in the direction of the glue chamber 9 is now blocked due to the closed valves, the cleaning fluid presses through the valve 8 and the line 11 to the glue outlet and exits there, pushing out the glue present in these parts. The path in the direction of the glue chamber 9, which is blocked for the cleaning fluid, is referred to as "hydraulically closed".

Die Figur 5 zeigt nun Einzelheiten einer bevorzugten Ausführungsform des Rückschlagventils. In dem Ventilgehäuse 24 befindet sich eine Pfanne 25, die mit einer nicht sichtbaren Öffnung versehen ist, über die das Fluid von der Fluidkammer 13 in das Gehäuse einströmen kann. Dabei wird die Kugel 26 angehoben. Gelangt nun eine Flüssigkeit in Richtung der Fluidkammer 13 strömend in das Ventilgehäuse 24, so wird die Kugel 26 in die Pfanne 25 gedrückt, so dass diese die Öffnung verschließt und die Flüssigkeit nicht in die Fluidkammer 13 gelangen kann. Ist der Druckunterschied zwischen der Flüssigkeit und dem Fluid in der Fluidkammer vergleichsweise gering, so kann es passieren, dass die Öffnung in der Pfanne 25 durch die Kugel nicht ausreichend und/oder nicht schnell genug verschlossen wird. Um das Verschließen insbesondere schneller erfolgen zu lassen, wirkt auf die Kugel eine Federkraft, welche in Richtung der Pfanne 25 gerichtet ist. Diese Federkraft kann durch ein beliebiges Federelement aufgebracht werden. Im gezeigten Ausführungsbeispiel ist dies eine einfache Feder 27, die sich auf ihrer der Kugel abgewandten Seite an geeigneten Abstützelementen 28 abstützen kann. Bezugszeichenliste 1 Vorrichtung zum Auftragen von Leim 2 Bahn 3 Gegendruckzylinder 4 Düseneinheit 5 Düsenplatte 6 Leimaustrittsöffnung 7 Düsenkopf 7a, b, c Teile des Düsenkopfes 8 Leimventile 9 Leimkanäle 10 Leimleitung 11 Leimzuführleitung 12 Fluidleitung 13 Fluidkammer 14 Mündung 15 Leimventil 16 Auffangwanne 17 18 19 20 Zulaufleitung 21 Ventil 22 Zulaufleitung 23 Ventil 24 Ventilgehäuse 25 Pfanne 26 Kugel 27 Feder 28 Abstützelement The FIG. 5 now shows details of a preferred embodiment of the check valve. In the valve housing 24 is a pan 25 which is provided with a non-visible opening through which the fluid from the fluid chamber 13 can flow into the housing. In this case, the ball 26 is raised. Now, if a liquid in the direction of the fluid chamber 13 flows into the valve housing 24, the ball 26 is pressed into the pan 25, so that it closes the opening and the liquid can not get into the fluid chamber 13. If the pressure difference between the liquid and the fluid in the fluid chamber is comparatively low, it may happen that the opening in the pan 25 is not adequately and / or not closed fast enough by the ball. In order to make the closing in particular faster, acts on the ball, a spring force which is directed in the direction of the pan 25. This spring force can be applied by any spring element. In the embodiment shown, this is a simple spring 27, which can be supported on its side facing away from the ball on suitable support elements 28. <B> LIST OF REFERENCES </ b> 1 Device for applying glue 2 train 3 Impression cylinder 4 nozzle unit 5 nozzle plate 6 glue outlet 7 nozzle head 7a, b, c Parts of the nozzle head 8th glue valves 9 glue channels 10 glue line 11 Leimzuführleitung 12 fluid line 13 fluid chamber 14 muzzle 15 glue valve 16 drip tray 17 18 19 20 supply line 21 Valve 22 supply line 23 Valve 24 valve housing 25 pan 26 Bullet 27 feather 28 supporting
