Description

Vorrichtung zum Auftragen von viskosen Medien  Device for applying viscous media
Die Erfindung betrifft eine Vorrichtung zum Auftragen von viskosen Medien, insbesondere von Klebstoffen, auf ein in Vorlaufrichtung bewegbares Substrat, mit einem Düsenkörper, der eine Mehrzahl von Abgabeöffnungen aufweisende Abgabedüsen umfasst, und mit einer Mehrzahl von Auftragsmodulen, mittels welchen die fluiden Medien intermittierend über die Abgabedüsen auf das Substrat abgebbar sind und welche an dem Düsenkörper angeordnet sind. The invention relates to a device for applying viscous media, in particular adhesives, to a substrate which can be moved in the advancing direction, with a nozzle body comprising a plurality of dispensing nozzles having dispensing openings, and with a plurality of application modules, by means of which the fluid media intermittently over the Dispensing nozzles are deliverable to the substrate and which are arranged on the nozzle body.
Eine derartige Vorrichtung ist beispielsweise aus der DE 103 20 813 B4 bekannt. Bei dieser Vorrichtung sind die Auftragsmodule in einer einzigen, sich quer zur Vorlaufrichtung erstreckenden Reihe dicht an dicht, d.h. mit einander zugewandten Seiten aneinandergrenzend, angeordnet. Jedes Auftragsmodul kommuniziert mit einer in dem Düsenkörper vorgesehenen Abgabedüse. Such a device is known for example from DE 103 20 813 B4. In this apparatus, the application modules are in close proximity to one another in a single row extending transversely to the advancing direction, i.e., in a single row. arranged adjacent to each other with sides facing each other. Each application module communicates with a dispensing nozzle provided in the nozzle body.
Damit mit einer derartigen Vorrichtung im Bedarfsfall das viskose Medium flächig ohne Zwischenräume zwischen den von den einzelnen Abgabedüsen abgegebenen Spuren auf das vorbeibewegte Substrat aufgetragen werden kann, müssen die Abgabeöffnungen eine Breite aufweisen, die zumindest der Breite des Auftragsmoduls entspricht. Die minimale Auftragsbreite ist dann also durch die Baubreite des Auftragsventils limitiert. Auch sind für den Fall, dass die Breite der Ab- gabeöffnung kleiner als die Baubreite der Auftragsmodule ist, die Möglichkeiten zur Erzielung unterschiedlicher Auftragsmuster auf dem Substrat durch dies von den Abgabeöffnungen definierte Auftragsfenster begrenzt. In order for such a device, if necessary, the viscous medium can be applied surface to surface without passing between the output from the individual dispensing nozzles on the moving past substrate, the discharge openings must have a width which corresponds at least to the width of the application module. The minimum application width is then limited by the width of the order valve. Also, in the event that the width of the discharge opening is smaller than the width of the order modules, the possibilities to achieve different job patterns on the substrate limited by this defined by the discharge openings order window.
Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Vorrichtung zum Auf- tragen von viskosen Medien, insbesondere von Klebstoffen zu schaffen, mit welcher eine größere Flexibilität hinsichtlich der Form der Auftragsmuster und kleinere minimale Auftragsbreiten realisiert werden können. The object of the invention is to provide an improved device for applying viscous media, in particular adhesives, with which greater flexibility with regard to the shape of the application pattern and smaller minimum application widths can be realized.
Diese Aufgabe wird durch die in Anspruch 1 wiedergegebene Vorrichtung gelöst. This object is achieved by the reproduced in claim 1 device.
Bei der erfindungsgemäßen Vorrichtung sind die Auftragsmodule in zumindest zwei quer zur Vorlaufrichtung des Substrats zueinander versetzten Reihen angeordnet. Die Breiten der Abgabeöffnungen der Abgabedüsen der einen Reihe der Auftragsmodule kann so schmaler als die Breite des zugehörigen Auftragsmoduls ausgebildet werden, so dass sich bei einer Abgabe von viskosen Medien nur über diese Reihe der Auftragsmodule auf dem Substrat ein streifenförmiger Auftrag ergeben würde. Die Abgabeöffnungen der Abgabedüsen der Auftragsmodule der mindestens zweiten Reihe, die quer zur Vorlaufrichtung des Substrats versetzt gegenüber den Auftragsmodulen der ersten Reihe angeordnet sind, sind zur wahlweisen Erzielung eines flächigen Auftrag in Breitenrichtung derart dimensioniert, dass die über diese Reihe abgegebenen Spuren von viskosen Medien die Zwischenräume zwischen den Spuren der ersten Reihe vollständig ausfüllen. Auch kann zwischen zwei benachbarten Auftragsmodulen einer Reihe ein Montagespalt belassen werden, wodurch die Austauschbarkeit einzelner Auftragsmodule erleichtert ist. In the apparatus according to the invention, the application modules are arranged in at least two rows offset from each other transversely to the direction of advance of the substrate. The widths of the discharge openings of the dispensing nozzles of one row of the application modules can be made narrower than the width of the associated application module, so that a dispensing of viscous media would result in a strip-like application only on this row of application modules on the substrate. The discharge openings of the dispensing nozzles of the order modules of the at least second row, which are arranged transversely to the advancing direction of the substrate offset from the order modules of the first row, are dimensioned for selectively achieving a flat order in the width direction such that the votes on this series traces of viscous media the Completely fill in spaces between the tracks of the first row. Also, a mounting nip can be left between two adjacent application modules of a row, whereby the interchangeability of individual job modules is facilitated.
Sind genau zwei quer zur Vorlaufrichtung des Substrats zueinander versetzte Reihen von Auftragsmodulen vorgesehen, so sind die Reihen vorzugsweise etwa um eine halbe Baubreite eines Auftragsmoduls versetzt angeordnet. Die minimale Breite der Abgabeöffnung kann dann auf die halbe Baubreite, d.h. gegenüber dem Stand der Technik auf die Hälfte reduziert werden. Sind drei Reihen vorgesehen, so wird vorzugsweise der seitliche Versatz zu den Auftragsmodulen der jeweils angrenzenden Reihe sowie die Breite der Abgabeöffnung ein Drittel der Baubreite eines Auftragsmoduls betragen, bei vier Reihen ein Viertel usw.. Grundsätzlich ist es möglich die Reihen von Auftragsmodulen samt zugehöriger Abgabedüsen in Vorlaufrichtung des Substrats hintereinander anzuordnen, so dass bezogen auf die Vorlaufrichtung zuerst die über die Abgabeöffnungen der ersten Reihe abgegebenen, fluiden Medien auf das Substrat auftreffen, dann die über die zweiten Abgabeöffnungen abgegebenen Medien etc. If exactly two rows of application modules offset from one another perpendicular to the advancing direction of the substrate are provided, the rows are preferably arranged offset by approximately half the width of a job module. The minimum width of the discharge opening can then be reduced to half the width, ie, compared to the prior art to the half. If three rows are provided, then preferably the lateral offset to the order modules of each adjacent row and the width of the discharge opening will be one third of the width of a job module, in four rows a quarter, etc. In principle, it is possible to arrange the rows of application modules together with associated delivery nozzles in the feed direction of the substrate one behind the other, so that, based on the advance direction, the fluid media discharged via the delivery openings of the first row strike the substrate first, then the media discharged via the second delivery openings, etc ,
Um einen möglichst gleichmäßigen, flächenhaften Auftrag der viskosen Medien auf dem Substrat auch quer zu dessen Vorlaufrichtung sicherzustellen, ist es je- doch wünschenswert, die von den verschiedenen Reihen der Auftragsmodule abgegebenen Spuren bezogen auf die Vorlaufrichtung des Substrats an derselben Stelle aufzubringen. Bei einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung sind benachbarte Reihen von Auftragsvolumen daher V-förmig zueinander um einen Neigungswinkel geneigt angeordnet. Es ist hierdurch mög- lieh, die Abgabeöffnungen sämtlicher Auftragsmodule auf einer quer zur Vorlaufrichtung verlaufenden Linie anzuordnen. In order to ensure as even a surface as possible application of the viscous media on the substrate transversely to the direction of advance, it is however desirable to apply the tracks emitted by the various rows of the application modules at the same point relative to the advancing direction of the substrate. In a preferred embodiment of the device according to the invention, adjacent rows of application volumes are therefore arranged in a V-shape with respect to one another at an inclination angle. It is thus possible to arrange the discharge openings of all the application modules in a line running transversely to the advance direction.
Der Neigungswinkel zwischen den benachbarten Reihen wird abhängig von der Baugröße der Auftragsmodule regelmäßig möglichst klein gewählt werden. Er liegt bei bevorzugten Ausführungsformen zwischen etwa 30° und 90°. The angle of inclination between the adjacent rows will be selected as small as possible on a regular basis, depending on the size of the order modules. It is in preferred embodiments between about 30 ° and 90 °.
Um die Gleichmäßigkeit des Auftrags quer zur Vorlaufrichtung des Substrats abermals zu verbessern, münden bei einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung die Abgabeöffnungen in einen Kanal, welchen in Flussrichtung der viskosen Medien eine Breitschlitzdüse nachgeschaltet ist. Derartige Breitschlitzdüsen, die beispielsweise aus der zum Stand der Technik genannten DE 103 20 813 B4 für sich genommen vorbekannt sind, glätten die über die einzelnen Abgabeöffnungen abgegebenen Spuren der viskosen Medien und können dafür sorgen, dass die Ränder benachbarter Spuren ineinan- der fließen. In order to further improve the uniformity of the application transversely to the direction of advance of the substrate, in a particularly preferred embodiment of the device according to the invention the discharge openings lead into a channel, which is followed by a slot die in the direction of flow of the viscous media. Such slot dies, which for example are known per se from the prior art DE 103 20 813 B4, smooth the traces of the viscous media emitted via the individual discharge openings and can ensure that the edges of adjacent tracks flow into one another.
Um die erfindungsgemäße Vorrichtung einfacher an verschiedene Auftragsbedingungen anpassen zu können, ist die Breitschlitzdüse vorzugsweise an einem abnehmbar an dem Düsenkörper angeflanschten Breitschlitzdüsenkörper angeord- net. So kann, wenn beispielsweise ein Auftrag fluider Medien in dünneren Schichten gewünscht wird, eine Breitschlitzdüse mit einer kleineren Schlitzbreite eingesetzt werden. In der Zeichnung ist - schematisch - ein Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung dargestellt. Es zeigen: In order to be able to adapt the device according to the invention more easily to different application conditions, the slot die is preferably arranged on a slot nozzle body which is detachably flanged to the nozzle body. net. Thus, if, for example, an order of fluid media in thinner layers is desired, a slot die with a smaller slot width can be used. In the drawing - is shown schematically - an embodiment of a device according to the invention. Show it:

Das als Ganzes mit 100 bezeichnete Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung umfasst fünf Auftragsmodule 1 , 2, 3, 4, 5, von denen die Auf- tragsmodule 1 , 3, 5 bis auf Montagespalte 6 dicht an dicht in einer ersten Reihe 7 angeordnet sind. Die Auftragsmodule 2, 4 sind in einer zweiten Reihe 8, wiederum bis auf einen Montagespalt 9 dicht an dicht, jedoch etwa um die Hälfte der Breite B eines Auftragsmoduls quer zur Vorlaufrichtung V eines vorbeibewegten Substrats S versetzt angeordnet. Die Auftragsmodule können in beliebiger, aus dem Stand der Technik zur intermittierenden Abgabe von viskosen Medien bekannter Weise ausgebildet sein. Sie sind an einem Düsenkörper 10 angebracht, der sich quer zur Vorlaufrichtung V des Substrats S erstreckt. Der Düsenkörper 10 weist hierzu eine erste Montagefläche 1 1 zur Montage der Auftragsmodule 1 , 3, 5 der ersten Reihe 7 sowie eine zweite Montagefläche 12 zur Montage der Auftragsmodule 2, 4 der zweiten Reihe 8 auf. Die Montageflächen 1 1 , 12 sind um einen Winkel Θ von etwa 130° zueinander geneigt, so dass die Auftragsmodule zueinander um einen Winkel φ von etwa 50° geneigt sind. Zur Stabilisierung der beiden Reihen 7, 8 der Auftragsmodule ist ein zwischen den beiden Reihen 7, 8 angeordneter Träger 13 vorgesehen. The exemplary embodiment of a device according to the invention designated as 100 comprises five application modules 1, 2, 3, 4, 5, of which the order modules 1, 3, 5 are arranged close to assembly gaps 6 in close proximity to one another in a first row 7. The application modules 2, 4 are arranged offset in a second row 8, again up to a mounting gap 9 close to each other, but approximately by half the width B of a job module transversely to the feed direction V of a vorbegeschewegten substrate S. The application modules can be formed in any known manner from the prior art for the intermittent delivery of viscous media. They are attached to a nozzle body 10, which extends transversely to the feed direction V of the substrate S. For this purpose, the nozzle body 10 has a first mounting surface 11 for mounting the application modules 1, 3, 5 of the first row 7 and a second mounting surface 12 for mounting the application modules 2, 4 of the second row 8. The mounting surfaces 1 1, 12 are inclined by an angle Θ of about 130 ° to each other, so that the application modules are inclined to each other by an angle φ of about 50 °. To stabilize the two rows 7, 8 of the application modules, a carrier 13 arranged between the two rows 7, 8 is provided.
Der Düsenkörper 10 umfasst Abgabedüsen 14, die jeweils einem Auftragsmodul 1 , 2, 3, 4, 5 zugeordnet sind, so dass das von einem Auftragsmodul abgegebene Medium durch eine Abgabeöffnung 15 der jeweiligen Abgabedüse 14 austritt. Sämtliche Abgabeöffnungen 15 münden auf einer sich quer zur Vorlaufrichtung V des Substrats S erstreckenden Linie L in einen Kanal 16, welchem in Flussrichtung der viskosen Medien eine Breitschlitzdüse 17 nachgeschaltet ist. Letztere ist an einem abnehmbar an dem Düsenkörper 10 angeflanschten Breitschlitzdüsen- körper 18 angeordnet, so dass sie im Bedarfsfalle leicht auswechselbar ist. The nozzle body 10 comprises dispensing nozzles 14 which are each assigned to an application module 1, 2, 3, 4, 5, so that the medium dispensed by an application module exits through a dispensing opening 15 of the respective dispensing nozzle 14. All delivery openings 15 open on a line L extending transversely to the advance direction V of the substrate S into a channel 16, which is followed by a slot die 17 in the direction of flow of the viscous media. The latter is arranged on a flat-slit nozzle body 18, which is detachably flanged to the nozzle body 10, so that it can easily be exchanged if necessary.
Wie bereits weiter oben erwähnt sind die Auftragsmodule 1 , 2, 3, 4, 5 in herkömmlicher Weise ausgebildet. Sie umfassen also elektrisch, elektromagnetisch, pneumatisch, hydraulisch, piezoelektrisch etc. betätigte Ventilanordnungen, mittels welcher von außen beispielsweise über Zuleitungen, die in der Zeichnung nicht dargestellt sind, zugeleitete fluide Medien intermittierend über die Abgabedüsen 14 durch die Abgabeöffnungen 15 abgebbar und mit Hilfe der Breitschlitzdüse 17 auf das Substrat S auftragbar sind. Die den Auftragsmodulen 1 , 2, 3, 4 zugeordneten Abgabeöffnungen 15 können - je nach auf dem vorbeibewegten Substrat aufzubringendem Auftragsmuster - unterschiedliche Öffnungsbreiten quer zur Vorlaufrichtung V des Substrats S aufweisen. Die Öffnungsbreiten müssen lediglich, sofern bereichsweise ein flächiger Linienauftrag gewünscht wird - aneinander angepasst sein. As already mentioned above, the application modules 1, 2, 3, 4, 5 are formed in a conventional manner. They thus include electrically, electromagnetically, pneumatically, hydraulically, piezoelectrically actuated valve arrangements, by means of which, for example via lines, which are not shown in the drawing, fluid media delivered intermittently via the discharge nozzles 14 through the discharge openings 15 and with the help of Slot die 17 can be applied to the substrate S. The dispensing openings 15 assigned to the application modules 1, 2, 3, 4 may have different opening widths transversely to the advance direction V of the substrate S, depending on the application pattern to be applied on the moved-over substrate. The opening widths only have to be adapted to one another, provided that a planar line application is desired in some areas.
In Fig. 1 ist schraffiert ein denkbares Auftragsmuster M dargestellt, wie es mit einer erfindungsgemäßen Vorrichtung realisierbar ist. Hierzu weist die dem Auftragsmodul 1 zugeordnete Abgabeöffnung eine Breite auf, die zu einer Auftragsspur A1 führt. Das Auftragsmodul 2, welches bei dem dargestellten Auftragsbei- spiel kürzer intermittierend betätigt wurde als das Auftragsmodul 1 , ist einer Abgabeöffnung 15 zugeordnet, welche die Auftragsspur A2 bewirkt. Die intermittierende Abgabe des fluiden Mediums über das Auftragsmodul 3 führt zu der Auftragsspur A3, Auftragsmodul 4 erzeugt die Spur A4 und Auftragsmodul 5 entsprechend A5. Aus diesem in Fig. 1 beispielhaft dargestellten Auftragsmuster wird ersichtlich, dass mit Hilfe der erfindungsgemäßen, zwei Reihen 7, 8 an Auftragsmodulen aufweisenden Vorrichtung 100 Auftragsspuren sowohl in bereichsweise flächenhafter, als auch in Spuren geringerer Breite auf ein vorbeibewegtes Substrat aufbringbar sind, als dies mit einer herkömmlichen, lediglich einer Reihe dicht an dicht angeordneter Auftragsmodule möglich wäre. Bezugszeichenliste: In Fig. 1 hatched a conceivable order pattern M is shown, as it is feasible with a device according to the invention. For this purpose, the dispensing opening assigned to the application module 1 has a width which leads to an application track A1. The order module 2, which has been operated intermittently in the illustrated order example as the order module 1, is associated with a delivery opening 15 which effects the application track A2. The intermittent discharge of the fluid medium via the order module 3 leads to the application track A3, order module 4 generates the track A4 and order module 5 corresponding to A5. From this order pattern illustrated by way of example in FIG. 1, it can be seen that with the aid of the apparatus 100 according to the invention having two rows 7, 8 of application modules, application marks can be applied to a moving substrate both in areal extent as well as in tracks of smaller width than with a conventional, only a row tightly arranged order modules would be possible.
