You can choose from a wide range of mixing ratios.

Dank einer einfach zu bedienenden Füllstation kann das Auftraggerät einfach, sicher und ohne Lufteinschluss wiederbefüllt werden. Die Füllstation erlaubt durch ihre einfache Handhabung ein schnelles und sicheres Wiederbefüllen des Auftraggerätes. Dieses System ist ideal für die Anwendung bei großer Mobilität und hoher Dosiersicherheit.Thanks to an easy-to-use filling station, the applicator can be refilled easily, safely and without air entrapment. The filling station allows a quick and safe refilling of the applicator due to its easy handling. This system is ideal for use with high mobility and high dosing safety.

Ein Auftraggerät mit seiner Düse, vorzugsweise als Mischdüse für Zweikomponentenklebstoff- und Dosieranwendungen, ist wesentlicher Bestandteil der Erfindung.An applicator with its nozzle, preferably as a mixing nozzle for two-component adhesive and dosing applications, is an integral part of the invention.

An dieses Auftraggerät des vorher beschriebenen Systems wird nun die erfindungsgemäße Lösung der Faltdüse am Ende der gegebenen Düse des Auftraggerätes angeschlossen.At this applicator of the system described above, the inventive solution of the folding nozzle is now connected at the end of the given nozzle of the applicator.

Das gegebene Auftraggerät besitzt eine Düse, welche zum Auftragen der entsprechenden Stoffe dienlich ist. Dabei ist es möglich, eine Einkomponentenkleb- bzw. Zweikomponentenkleb- und Dichtstoffanwendung zu realisieren. Wird eine Zweikomponentenvariante gewählt, wird die jeweilige Komponente in der Düse gemischt und am Ende der Düse auf das zu bearbeitende Material aufgetragen.The given applicator has a nozzle, which is useful for applying the corresponding substances. It is possible to realize a Einkomponentenkleb- or Zweikomponentenkleb- and sealant application. If a two-component variant is selected, the respective component is mixed in the nozzle and applied to the material to be processed at the end of the nozzle.

Erfindungswesentlich ist nun, dass an dieser Düse des Auftraggerätes eine Faltdüse als Aufsatz am Ende der Düse des Auftraggerätes angeschlossen wird. Erfindungswesentlich ist dabei, dass diese Faltdüse aus einem Stück besteht. Dieser Vorteil ist dahingehend wesentlich, dass bei der Herstellung dieser Faltdüse, welche als Wegwerfartikel angefertigt wird, ein einziges Spritzgießwerkzeug notwendig ist, was den Vorteil gegenüber dem Stand der Technik darstellt.Essential to the invention is now that at this nozzle of the applicator a folding nozzle is attached as an attachment at the end of the nozzle of the applicator. Essential to the invention is that this folding nozzle consists of one piece. This advantage is essential in that in the manufacture of this folding nozzle, which is made as a disposable article, a single injection mold is necessary, which is the advantage over the prior art.

Die Faltdüse hat in ihrer Mitte ein Mittelstück, worauf entsprechende Düsen als Austrittsdüsen angeordnet sind. Die Größe des Mittelstückes und der dazugehörigen Austrittsdüsen ist je nach Anwendungsfall variabel. Über die gegebenen Knickkanten an der Seite des Mittelstückes kann man nun die Faltdüse an die vorhandene Düse des Auftraggerätes formschlüssig und dicht anschließen. Dabei wird die Düse des Auftraggerätes bis zum Anfang einer Verteil- und Druckausgleichskammer der Faltdüse eingelegt und über vorhandene Abdichtstege eingerastet. Durch das Umfalten der Faltdüse wird nun über eine gegebene Rasterkante mit vorhandenen Rastern auf dem gegenüberliegenden Ansatzstück der Faltdüse ein festes Einrasten dieser durchgeführt.The folding nozzle has in its center a center piece, whereupon corresponding nozzles as outlet nozzles are arranged. The size of the center piece and the associated outlet nozzles is variable depending on the application. About the given creases on the side of the center piece you can now connect the folding nozzle to the existing nozzle of the applicator form-fitting and tight. In this case, the nozzle of the applicator is inserted to the beginning of a distribution and pressure equalization chamber of the folding nozzle and engaged via existing Abdichtstege. Due to the folding over of the folding nozzle, a fixed snap-in of the folding nozzle is now carried out on a given raster edge with existing rasters on the opposite extension piece of the folding nozzle.

Die vorhandenen ineinander tauchenden Dichtstege und die vorgegebenen Abdichtstege garantieren eine entsprechende Dichtheit, um einen Austritt der durch Druck beinhalteten Komponenten zu verhindern. Durch Betätigen des Auftraggerätes über die Düse und den Aufsatz als Faltdüse kann nun über die vorhandenen Austrittsdüsen ein entsprechender Auftrag der Komponenten auf einem Werkstoff etc. ausgeführt werden. Wichtig ist dabei, dass die gegebenen ineinander tauchenden Dichtstege in einen jeweils vorhandenen Führungssteg auf einer Seite der Faltdüse eingreifen und somit eine Dichtheit der Faltdüse als Aufsatz und der Düse des Auftraggerätes gegeben ist.The existing dipping sealing webs and the predetermined sealing webs guarantee a corresponding tightness, in order to prevent leakage of the components contained by pressure. By pressing the applicator on the nozzle and the attachment as Faltdüse now a corresponding order of the components on a material, etc. can be performed on the existing outlet nozzles. It is important that the given dipping sealing webs engage in a respective existing guide web on one side of the folding nozzle and thus a tightness of the folding nozzle is given as an attachment and the nozzle of the applicator.

Des Weiteren ist bei der Düse in einem bestimmten Abstand vor dem Austritt eine Ringfeder gegeben, worin schlüssig jeweils eine Ringnut in den Ansatzstücken eingreift. Somit wird auch die Dichtheit zwischen der Düse und der Faltdüse erhöht.Furthermore, in the nozzle at a certain distance before exiting an annular spring is given, in which a respective annular groove in the Engaging pieces. Thus, the tightness between the nozzle and the folding nozzle is increased.

Die Verteil- und Druckausgleichskammer der Faltdüse dient zur Erzeugung einer dichtenden Vorspannung, um einen Auftrag der Komponenten aus den Austrittsdüsen ohne Luftzufuhr zu gewährleisten.The distribution and pressure compensation chamber of the folding nozzle is used to create a sealing bias to ensure an order of the components from the outlet nozzles without air supply.

Nachstehend wird die Erfindung an einem Ausführungsbeispiel näher erläutert.The invention will be explained in more detail using an exemplary embodiment.

Des Weiteren wird eine Abdichtung durch das Zusammenklappen der Faltdüse 1 hervorgerufen über die ineinander tauchenden Dichtstege 11 und 11'. Dazu dient ein jeweiliger in der rechten Seite der Verteil- und Druckausgleichskammer 8 gegebener Führungssteg 9 gemäß Unteransicht der Figur 4. Klappt man nun die Faltdüse 1 über die Düse 2 des Auftraggerätes zusammen, umschließen die Abdichtstege 12 und 13 des jeweiligen Ansatzstückes mit Raster 4 und des Ansatzstückes mit Rasterkante 4' den Zwischenraum zwischen der Düse 2 und der Verteil- und Druckausgleichskammer 8. Gleichzeitig wird über die ineinander tauchenden Dichtstege 11 und 11' sowie den Führungssteg 9 innerhalb der Verteil- und Druckausgleichskammer 8 eine Abdichtung der Faltdüse 1 vor Austritt der Komponenten bei Druckbeaufschlagung garantiert. Beim Zusammenklappen der Faltdüse 1 sind ein Ansatzstück mit Raster 4 und ein Ansatzstück mit Rasterkante 4' mit einer Rasterkante 6 gegeben, womit ein einfaches Zusammenklappen über das Ende der Düse 2 des Auftraggerätes möglich ist. Auf Grundlage der vorhandenen Dichtungselemente Abdichtsteg 12, Abdichtsteg 13, ineinander tauchender Dichtsteg 11 und 11' und Führungssteg 9 ist eine absolute Dichtheit des Komponentenmediums bei Druckbeaufschlagung und Ausspritzen über die Austrittsdüsen 3 gegeben.Furthermore, a seal is caused by the folding of the folding nozzle 1 via the dipping sealing webs 11 and 11 '. Serves a respective in the right side of the distribution and pressure compensation chamber 8 given guide bar 9 according to the bottom view of FIG. 4 , If you fold now the folding nozzle 1 on the nozzle 2 of the applicator, enclose the Abdichtstege 12 and 13 of the respective lug with grid 4 and the extension piece with raster edge 4 'the space between the nozzle 2 and the distribution and pressure equalization chamber 8. At the same time the intermeshing sealing webs 11 and 11 'and the guide web 9 within the distribution and pressure equalization chamber 8, a seal of the folding nozzle 1 before discharge of the components when pressurized guaranteed. When folding the folding nozzle 1 an attachment piece with grid 4 and an extension piece with raster edge 4 'are given with a raster edge 6, whereby a simple folding over the end of the nozzle 2 of the applicator is possible. On the basis of the existing sealing elements Abdichtsteg 12, Abdichtsteg 13, dive into each other sealing web 11 and 11 'and guide web 9 is an absolute tightness of the component medium when pressurized and ejection through the outlet nozzles 3 given.

Wesentlich ist auch weiterhin, dass die Dichtheit erreicht wird, indem eine vorhandene Ringfeder 14 auf der Düse 2 in einem bestimmten Abstand von dem Austritt der Düse 2 gegeben ist. Diese Ringfeder 14 und eine vorhandene Ringnut 15 sind an dem jeweiligen Ansatzstück mit Raster 4 und Ansatzstück mit Rasterkante 4' vorhanden. Beim Aufsetzen der Faltdüse 1 auf die Düse 2 wird über die jeweilige Ringfeder 14 der Düse 2 und die jeweilige Ringnut 15 des Ansatzstückes mit Raster 4 und des Ansatzstückes mit Rasterkante 4' die Faltdüse 1 mit der Düse 2 dicht verbunden.It is also essential that the tightness is achieved by an existing annular spring 14 on the nozzle 2 at a certain distance from the Outlet of the nozzle 2 is given. This annular spring 14 and an existing annular groove 15 are present at the respective end piece with grid 4 and extension piece with raster edge 4 '. When placing the folding nozzle 1 on the nozzle 2, the folding nozzle 1 is connected to the nozzle 2 via the respective annular spring 14 of the nozzle 2 and the respective annular groove 15 of the extension piece with grid 4 and the extension piece with raster edge 4 '.

Aus der Figur 2 ist ersichtlich, wie die entsprechenden Raster 5 und die Rasterkante 6 des jeweiligen Ansatzstückes mit Raster 4 und Ansatzstückes mit Rasterkante 4' verbunden sind. Dabei ist eine einfache Klemmrastung vorteilhaft. Die an das Ansatzstück mit Raster 4 und an das Ansatzstück mit Rasterkante 4' anbindende Verteil- und Druckausgleichskammer 8 kann je nach Anwendungsfall und Größe definiert werden. Daraufhin wird auch das entsprechende Mittelstück 10 so angepasst, dass eine verschiedene Anzahl von Austrittsdüsen 3 oder auch eine andere Austrittsdüsenform - wie ein langes Rechteck oder ein Schwingungsaustritt - möglich sind.From the FIG. 2 It can be seen how the corresponding grid 5 and the grid edge 6 of the respective extension piece with grid 4 and extension piece with grid edge 4 'are connected. In this case, a simple clamping lock is advantageous. Depending on the application and size, the distribution and pressure compensation chamber 8 connecting to the attachment piece with the grid 4 and to the attachment piece with the grid edge 4 'can be defined. Then, the corresponding centerpiece 10 is adapted so that a different number of outlet nozzles 3 or another outlet nozzle shape - such as a long rectangle or a vibration outlet - are possible.

Erfindungswesentlich ist hierbei beschrieben, dass die Anwendung einer Faltdüse 1 einfach und praktisch ausgeführt ist. Vorteilhaft ist dabei, dass die Faltdüse 1 aus einem einzigen Stück besteht und über die entsprechenden Knickkanten 7 und 7' um eine vorhandene Düse 2 eines Auftraggerätes fest und dicht verschlossen werden kann.Essential to the invention is described here that the application of a folding nozzle 1 is simple and practical. It is advantageous that the folding nozzle 1 consists of a single piece and can be firmly and tightly closed about the corresponding creasing edges 7 and 7 'to an existing nozzle 2 of a job unit.
