Abstract

A device for dispensing flowing media, in particular hot-melt adhesives, cold adhesive, lubricants, paints or the like, in a metered manner, comprises a deposition head having numerous flowing-media feed ducts opening to a boundary surface thereof, and at least one deposition module mounted on the boundary surface and comprising a nozzle head to deposit the flowing media in a particular pattern, such as spots, beads or the like, on a moving substrate. The device comprises at least two mounting pins projecting from the boundary surface and passing through and beyond boreholes of the deposition module. At least one clamping element acting, at least indirectly, on the deposition module is provided in end zones of the mounting pins which project from the deposition module. Affixation or exchange of the deposition module is thus significantly simplified by slipping the deposition module onto the mounting pins and fastening the clamping element.

Description

Die Erfindung betrifft eine Vorrichtung zur dosierten Abgabe von strömenden Medien, insbesondere Schmelzkleber, Kaltleim, Schmierstoffe, Farben od. dgl., mit einem Auftragskopf, der eine Begrenzungsfläche aufweist, in der zahlreiche, für ein strömendes Medium vorgesehene Zuführungskänale münden, und mindestens einem an der Begrenzungsfläche angeordneten Auftragsmodul, welches mit einem Düsenkopf zur Aufbringung von Klebepunkten, Klebelinien od. dgl. auf einem vorbeibewegten Substrat versehen ist.The invention relates to a device for metered delivery of flowing media, in particular hot melt adhesive, cold glue, lubricants, colors od. Like., With an applicator head, which has a boundary surface, in the numerous, provided for a flowing medium supply channels open, and at least one the boundary surface arranged application module, which od with a nozzle head for applying adhesive dots, adhesive lines. The like. Is provided on a moving past substrate.

Eine derartige Vorrichtung ist aus dem druckschrift-EP-A-0719591 bekannt, bei der die Auftragsmodule jeweils mit zwei Zylinderkopfschrauben an den der Versorgung des Auftragsmoduls dienenden Auftragskopf befestigt werden kann.Such a device is known from the document EP-A-0719591, in which the application modules can be attached in each case with two cylinder head screws to the order of the supply of the application module application head.

Dieses prinzipiell kostengünstige System hat jedoch den Nachteil, daß beim Wechsel der Auftragsmodule - der zum Zwecke der Verlängerung der Maschinenstellstandszeiten im heißen Zustand geschieht - es immer wieder vorkommt, daß Klebstoff aus dem Leimkanal tropft und in die Aufnahmegewinde der Zylinderkopfschrauben fließt. Da dieser Klebstoff mit der Zeit verbrennt, bildet er eine harte Kruste, die beim nächsten Auftragsmodulwechsel die Gängigkeit des Gewindes beeinträchtigt und das Montieren des Auftragsmoduls erschwert.However, this principle cost-effective system has the disadvantage that when changing the job modules - which happens for the purpose of extending the Maschinenstellstandszeiten in the hot state - it happens again and again that adhesive drips from the glue channel and flows into the receiving thread of the cylinder head bolts. As this adhesive burns over time, it forms a hard crust which, at the next job module change, impairs the thread's ease of movement and makes it difficult to mount the job module.

Darüber hinaus müssen bei der Montage der Auftragsmodule vom Montagepersonal die Gewinde mit den Schrauben ertastet werden, um die genaue Montageposition zu finden. Dies ist insbesondere bei heißen Zustand der Vorrichtung schwierig. Auch kann es dabei immer wieder passieren, daß Schrauben in die Maschine fallen und so verloren gehen bzw. erst Ersatzschrauben beschafft werden müssen.In addition, when installing the job modules from the assembly staff, the thread with the Keys are sensed to find the exact mounting position. This is difficult especially when the device is hot. It can also happen over and over again that screws fall into the machine and go so lost or replacement screws must be procured.

Letztendlich können die Gewinde so beschädigt sein, daß eine Befestigung eines neuen Auftragsmoduls nicht mehr möglich ist, so daß der gesamte Auftragskopf aus der Maschine ausgebaut und neue Zylinderkopfschrauben eingesetzt werden müssen. Dies bedeutet dann einen längeren Produktionsausfall.Finally, the threads can be damaged so that attachment of a new job module is no longer possible, so that the entire application head removed from the machine and new cylinder head bolts must be used. This then means a longer production downtime.

Ausgehend von dem oben geschilderten Stand der Technik besteht nun die Aufgabe der Erfindung darin, eine neue Vorrichtung zur dosierten Abgabe von strömenden Medien zu entwickeln, bei der die Auftragsmodul-Befestigung bzw. der Austausch deutlich vereinfacht wird.Based on the above-described prior art, the object of the invention is now to develop a new device for metered delivery of flowing media, in which the order module attachment or replacement is significantly simplified.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1, insbesondere den Merkmalen des Kennzeichenteils, wonach die Begrenzungsfläche mit mindestens zwei Aufnahmebolzen versehen ist, die durch Bohrungen des Auftragsmodul hindurchgreifen und daß auf die aus dem Auftragsmodul hervorragenden Endbereichen der Aufnahmebolzens wenigstens mittelbar ein gegen das Auftragsmodul wirkendes Spannelement angeordnet ist.The solution of this problem arises from the features of claim 1, in particular the features of the characterizing part, according to which the boundary surface is provided with at least two locating pins which pass through holes of the application module and that at least indirectly from the order module outstanding end portions of the locating pin against the order module acting clamping element is arranged.

Die erfindungsgemäße Vorrichtung hat zunächst einmal den wesentlichen Vorteil, daß die zur Befestigung der Aufnahmebolzen im Auftragskopf vorgesehenen Gewinde bei Wechsel des Auftragsmoduls nicht gelöst werden müssen und sie somit einerseits keinem Verschleiß durch Montagevorgänge ausgesetzt sind und andererseits auch nicht durch ausfließenden Klebstoff beschädigt werden können. Auch kann durch einfaches Aufschieben des Auftragsmoduls auf die fest am Auftragskopf angeordneten Aufnahmebolzen bereits eine sichere Vormontagestellung erreicht werden, wobei dann durch Betätigung des Spannelementes eine unverrückbare Befestigung garantiert wird.The device according to the invention has, first of all, the significant advantage that the threads provided for fastening the locating bolts in the application head do not have to be loosened when the application module is changed, and thus on the one hand no wear due to assembly operations are exposed and on the other hand can not be damaged by leaking adhesive. Also can be achieved by simply pushing the job module on the fixedly arranged on the application head receiving bolt already a safe pre-assembly, in which case an immovable attachment is guaranteed by pressing the clamping element.

Auf vorteilhafte Weise kann auch zwischen dem Spannelement und dem Auftragsmodul eine beide Endbereiche der Aufnahmebolzen erfassende Widerlagerplatte angeordnet sein.In an advantageous manner, an abutment plate which detects both end regions of the locating bolt can also be arranged between the tensioning element and the application module.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Endbereiche der Aufnahmebolzen jeweils mit einem Spannkopf versehen, der einen gegenüber einer vorgelagerten Eingriffsnut erweiterten Durchmesser aufweist, wobei die für die Widerlagerplatte vorgesehenen Eingriffsnut mit einem gegenüber dem Aufnahmebolzen verringerten Durchmesser versehen ist und daß die Widerlagerplatte als Schiebeplatte ausgebildet ist, die zur Aufnahme der Endbereiche der Aufnahmebolzen in Schwerkraftrichtung verlaufende Langlöcher aufweist, die entgegen der Schwerkraftrichtung einen ersten Bereich mit einem Durchmesser aufweisen, der einen den Durchmesser des Spannkopfes übersteigenden Durchmesser aufweist, während in Schwerkraftrichtung in einem zweiten Bereich der Durchmesser der Langlöcher nur geringfügig größer ist als der Durchmesser des Bolzens im Bereich der Eingriffsnut.In a preferred embodiment of the invention, the end portions of the locating pins are each provided with a clamping head having an enlarged diameter relative to an upstream engaging groove, the engagement groove provided for the abutment plate being provided with a reduced diameter relative to the locating pin and the abutment plate being formed as a sliding plate is, which has for receiving the end portions of the locating bolt in the direction of gravity extending slots having against the direction of gravity a first region having a diameter having a diameter of the clamping head diameter exceeding, while in the direction of gravity in a second region of the diameter of the slots only slightly greater than the diameter of the bolt in the region of the engagement groove.

Bei dieser Ausführungsform ist die Widerlagerplatte auf vorteilhafte Weise so ausgebildet, daß sie im nicht verspannten Zustand die Vormontageposition sichert und im verspannten Zustand eine Verspannung der als Schiebeplatte ausgebildeten Widerlagerplatte erreicht wird.In this embodiment, the abutment plate is advantageously designed so that it secures the pre-assembly in the non-tensioned state and in clamped state, a tension of the sliding plate formed as an abutment plate is achieved.

Bei einer besonders bevorzugten Ausführungsform der Erfindung wird das Spannelement aus einer in einer Gewindebohrung der Widerlagerplatte/Schiebeplatte angeordneten Druckschraube gebildet, die sich an einer Außenfläche des Auftragsmoduls abstützt.In a particularly preferred embodiment of the invention, the clamping element is formed from a pressure screw arranged in a threaded bore of the abutment plate / sliding plate, which is supported on an outer surface of the application module.

Bei dieser Ausführungsform kann lediglich durch eine halbe Umdrehung der Druckschraube der notwendige Andruck des Auftragsmoduls an den Auftragskopf erzeugt werden.In this embodiment, only by a half turn of the pressure screw the necessary pressure of the application module can be generated to the application head.

Weitere Vorteile der Erfindung ergeben sich aus den nachfolgenden Ansprüchen sowie aus der Beschreibung eines Ausführungsbeispiels. Es zeigen:

  • Fig. 1 eine Schnittdarstellung eines Auftragskopfes einschließlich Auftragsmodul,
  • Fig. 2 eine perspektivische Teildarstellung eines Auftragskopfes mit zahlreichen Auftragsmodulen gemäß Fig. 1,
  • Fig. 3 Explosionsdarstellung einer Befestigungsvorrichtung für das Auftragsmodul,
  • Fig. 4 eine Stirnansicht von Auftragskopf und Auftragsmodulen im befestigten Zustand.
Further advantages of the invention will become apparent from the following claims and from the description of an embodiment. Show it:

In den Zeichnungen ist eine Vorrichtung zur dosierten Abgabe von strömenden Medien insgesamt mit der Bezugsziffer 10 bezeichnet.In the drawings, a device for the metered delivery of flowing media is designated overall by the reference numeral 10.

Eine derartige Vorrichtung 10 weist einen Auftragskopf 11 und mindestens ein Auftragsmodul 12 auf, welches mit einem Düsenkopf 13 versehen ist.Such a device 10 has an application head 11 and at least one application module 12, which is provided with a nozzle head 13.

In der Fig. 1 ist die Vorrichtung 10 im einzelnen dargestellt, wobei nur diejenigen Elemente nachfolgend beschrieben werden sollen, die einen Bezug zur Erfindung aufweisen. Die Zuführung des über das Auftragsmodul 12 kontrolliert abzugebenen Leimes erfolgt zunächst über einen Filterblock 14 und einem Verbindungskanal 15 zum Druckverteilungskanal 16, der über einen weiteren Kanal 17 mit einem Hauptverteilungskanal 18 verbunden ist. Vom Hauptverteilungskanal 18 gehen zahlreiche Leimführungskanäle 19 ab, die in einer zum Auftragsmodul 12 weisenden Begrenzungsfläche 20 münden. Die Mündungsbereiche der Leimzuführungskanäle 19 korrespondieren nach der Befestigung der Auftragsmodule 12 mit entsprechenden, nicht dargestellten Leimzuführungskanälen im Auftragsmodul 12.In Fig. 1, the device 10 is shown in detail, wherein only those elements are to be described below, which have a relation to the invention. The feed of the glue to be delivered via the application module 12 is initially effected via a filter block 14 and a connecting channel 15 to the pressure distribution channel 16, which is connected via a further channel 17 to a main distribution channel 18. From the main distribution channel 18, there are numerous glue guide channels 19, which terminate in a boundary surface 20 facing the application module 12. The mouth regions of the glue supply channels 19 correspond to the attachment of the application modules 12 with corresponding glue supply channels (not shown) in the order module 12.

Damit der in der Vorrichtung 10 verwendete Heißleim immer eine gleichmäßige und ausreichend hohe Temperatur aufweist, ist im Bereich der vorher beschriebenen Leimzuführung eine Heizpatrone 21 angeordnet. Darüber hinaus ist unterhalb der Leimzuführung ein Lufterhitzer 22 vorhanden, der die notwendige erwärmte Sprühluft zur Verfügung stellt.In order for the hot glue used in the device 10 to always have a uniform and sufficiently high temperature, a heating cartridge 21 is arranged in the region of the previously described glue feed. In addition, an air heater 22 is provided below the glue supply, which provides the necessary heated spray air available.

Letztendlich erkennt man in der Fig. 1 eine Befestigungsvorrichtung 23 die im einzelnen noch nachfolgend beschrieben werden soll.Finally, one recognizes in Fig. 1, a fastening device 23 which will be described in detail below.

In der Fig. 2 ist die Vorrichtung 10 ausschnittweise perspektivisch dargestellt. Man erkennt, daß am Auftragskopf 11 bereits vier Auftragsmodule 12 mittels Befestigungsvorrichtungen 23 befestigt sind, wobei an der fünften Befestigungsposition zwei Aufnahmebolzen 24 zu erkennen sind, die in Gewindebohrungen 25 der Begrenzungsflächen 20 angeordnet sind. Zum Erreichen einer Vormontagestellung kann nun das Auftragsmodul 12 aufgrund im letzteren vorhandener, jedoch nicht dargestellter Bohrungen auf die Aufnahmebolzen 24 aufgeschoben werden.2, the device 10 is shown in fragmentary perspective view. It can be seen that four application modules 12 are already attached to the application head 11 by means of fastening devices 23, wherein two locating bolts 24 can be seen at the fifth fastening position, which are arranged in threaded bores 25 of the boundary surfaces 20. In order to achieve a pre-assembly position, the application module 12 can now be slid onto the locating bolts 24 due to the boreholes 24 present in the latter, but not shown.

Zur Erläuterung der Befestigung des Auftragsmoduls 12 am Auftragskopf 11 werden zunächst die in Fig. 3 dargestellten Einzelteile der Befestigungsvorrichtung 23 eingehend beschrieben. Die Befestigungsvorrichtung 23 weist zunächst die vorgenannten Aufnahmebolzen 24 auf. An dem zur Begrenzungsfläche 20 weisenden Endbereich ist der Aufnahmebolzen 24 mit einem Gewinde 26 sowie einem Anschlagring 27 versehen. Daran anschließend ist ein Distanzstück 28, welches eine nicht dargestellte Bohrung des Auftragsmoduls 12 durchgreift, eine Eingriffsnut 29 für eine Schiebeplatte 30 sowie ein Spannkopf 31 vorhanden. Der Aufnahmebolzen 24 weist im Bereich der Eingriffnut 29 einen Durchmesser d1 und im Bereich des Spannkopfes 31 einen Durchmesser d2 auf.To explain the attachment of the application module 12 on the application head 11, the individual parts of the fastening device 23 shown in Fig. 3 will first be described in detail. The fastening device 23 initially has the aforementioned locating bolts 24. At the end face facing the boundary surface 20, the locating pin 24 is provided with a thread 26 and a stop ring 27. This is followed by a spacer 28 which passes through a bore, not shown, of the application module 12, an engagement groove 29 for a sliding plate 30 and a clamping head 31 is present. The locating pin 24 has a diameter d 1 in the area of the engagement groove 29 and a diameter d 2 in the area of the clamping head 31.

Des weiteren weist die Befestigungsvorrichtung 23 die Schiebeplatte 30 auf, die in ihrem oberen Bereich (s. Fig. 2) mit zwei beabstandeten Langlöcher 32 für die Aufnahmebolzen 24 versehen ist, zwischen denen eine Gewindebohrung 33 für eine mit einem Innensechskant versehene Druckschraube 34 angeordnet ist. Oberhalb der Gewindebohrung 33 ist darüber hinaus noch eine Bohrung 35 für einen Führungsstift 36 vorhanden.Furthermore, the fastening device 23 has the sliding plate 30, which is provided in its upper region (see Fig. 2) with two spaced slots 32 for the locating pins 24, between which a threaded bore 33 is arranged for a pressure screw 34 provided with a hexagon socket , Above the threaded bore 33 is still a bore 35 for a guide pin 36 is present.

Die Langlöcher 32 weisen in ihrem oberen Bereich einen Durchmesser d3 auf, der geringfügig größer als der Durchmesser d2 des Spannkopfes 31 ist, während der Durchmesser d4 des unteren Bereiches der Langlöcher 32 kleiner ist als der Durchmesser d2 des Spannkopfes (31) und etwas größer als der Durchmesser d1 im Bereich der Eingriffnut 29. Die Begründung für diese verschiedenen Durchmesserverhältnisse wird nachfolgend noch gegeben.The slots 32 have in their upper region a diameter d 3 , which is slightly larger than the diameter d 2 of the clamping head 31, while the diameter d 4 of the lower portion of the slots 32 is smaller than the diameter d 2 of the clamping head (31). and slightly larger than the diameter d 1 in the region of the engagement groove 29. The reason for these different diameter ratios will be given below.

Unterhalb der Langlöcher 32 sind letztendlich noch zwei Langlöcher 37 angeordnet, die zur Aufnahme von Schulterschrauben 38 dienen, welche durch Befestigung an einer Außenfläche 39 des Auftragsmoduls 12 einen definierten Bewegungsspalt für die Schiebeplatte 30 zur Verfügung stellen. Mit Hilfe dieser Schulterschrauben 38 wird die vertikal verlaufende Schiebeplatte 30 unverlierbar am Auftragsmodul 12 gehalten. Des weiteren greift der Führungsstift 36 in eine Nut 40 der Außenfläche 39 ein und sorgt so für eine zusätzliche Führung der Schiebeplatte 30.Below the elongated holes 32 two slots 37 are finally arranged, which serve to receive shoulder screws 38, which provide a defined movement gap for the sliding plate 30 by attachment to an outer surface 39 of the application module 12. With the help of these shoulder screws 38, the vertically extending slide plate 30 is held captive on the application module 12. Furthermore, the guide pin 36 engages in a groove 40 of the outer surface 39 and thus provides additional guidance of the sliding plate 30.

Wenn nun - wie in Fig. 2 dargestellt - ein Auftragsmodul 12 am Auftragskopf 11 befestigt werden soll, kann das mit einer Schiebeplatte 30 versehene Auftragsmodul 12 zunächst auf die Aufnahmebolzen 24 soweit aufgeschoben werden, daß die Spannköpfe 31 aus der Schiebeplatte 30 im Bereich des Durchmessers d3 herausragen. In dieser Stellung ist zunächst einmal eine sichere Vormontageposition erreicht.If, as shown in FIG. 2, an application module 12 is to be fastened to the application head 11, the application module 12 provided with a sliding plate 30 can first be pushed onto the mounting bolts 24 to such an extent that the clamping heads 31 move out of the sliding plate 30 in the region of the diameter d 3 protrude. In this position, a safe pre-assembly position is initially reached.

Wenn man nun die Schiebeplatte 30 entgegen der Schwerkraft nach oben bewegt erreicht der Spannkopf 31 sowie die Eingriffnut 29 den Bereich des Durchmessers d4 des Langloches 32, wodurch der Spannkopf 31 die Funktion eines Widerlagers erhält. Dies ist insofern von Bedeutung, als das dann als nächster Schritt die Druckschraube 34 beispielsweise durch eine halbe Umdrehung in Richtung der Außenfläche 39 des Auftragsmoduls 12 bewegt wird und eine Verspannung der Schiebeplatte 30 bei gleichzeitiger Anpressung des Auftragsmoduls 12 an die Begrenzungsfläche 20 des Auftragskopfes 11 herbeiführt (s. Fig. 4). Nunmehr ist eine unverrückbare Befestigung des Auftragsmoduls 12 erreicht, die jedoch jederzeit durch Lösen der Druckschraube 34 wieder aufgehoben werden kann.If one now moves the sliding plate 30 upwards against gravity, the clamping head 31 reaches and the engagement groove 29 the region of the diameter d 4 of the elongated hole 32, whereby the chuck 31 receives the function of an abutment. This is important insofar as the next step, the pressure screw 34 is moved for example by a half turn in the direction of the outer surface 39 of the application module 12 and causes a distortion of the sliding plate 30 with simultaneous pressing of the application module 12 to the boundary surface 20 of the applicator head 11 (see Fig. 4). Now an immovable attachment of the application module 12 is reached, however, can be canceled at any time by loosening the pressure screw 34 again.
