Abstract

An applicator for curtain-pouring plastics or the like material of pourable consistency in which a base plate contains, inserted in a recess thereof, an applicator die block provided with a slit-shaped pouring orifice. On the base plate there are articulatedly mounted two half shells, forming an applicator head and adapted to be spread apart, and sealed with each other and with the base plate by means of sealing strips. Thus, there is no need for a re-adjustment of the orifice after each opening of the applicator head. Also, the width and/or length of the orifice can be readily changed by exchanging the applicator die block, and the entire structure is simple and of relatively low cost.

Description

Die Erfindung betrifft einen Giesskopf für den Vorhangguss gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a casting head for curtain casting according to the preamble of claim 1.

Ein Giesskopf dieser Art ist Beispielweise aus der Veröffentlichung DE-B-1 190 367 bekannt.A casting head of this type is known, for example, from publication DE-B-1 190 367.

Der Vorhangguss ist heute ein weit verbreitetes Verfahren zur Beschichtung von Objekten aller Art. So wird der Vorhangguss z. B. in der Fotoindustrie bei der Herstellung von fotografischen Materialien, für die Lackierung von Holz- und Metallplatten und neuerdings auch für die Beschichtung von elektrischen Leiterplatten mit z.B. Lötstoplack oder dergleichen eingesetzt.Curtain casting is a widely used process for coating objects of all kinds. B. in the photo industry in the production of photographic materials, for painting wood and metal plates and more recently for the coating of electrical circuit boards with e.g. Solder resist or the like used.

Für das Auftragen von Lackbeschichtungen wird üblicherweise ein Schlitzgiesser verwendet, das ist ein Giesskopf mit einem verstellbaren Gießspalt an seinem unteren Ende, durch den die Beschichtungsmasse dosiert austritt und von dort dann in einem frei fallendem Vorhang auf das zu beschichtende Gut niedersinkt. Ein bekannter solcher Giesskopf besteht aus zwei an ihrem oberen Ende aneinander angelenkten Backen oder Schalen, an deren unteren Enden je eine messerartige Leiste vorgesehen ist, welche Leisten zwischen sich den Gießspalt bilden, wobei die Breite bzw. Weite des Gießspalts durch gegenseitiges Annähern oder Entfernen der beiden Giesskopfschalen reguliert wird. Zum Reinigen des Giesskopfs kann eine der beiden Schalen hochgeklappt und dadurch der Giesskopf geöffnet werden.A slotted caster is usually used for the application of lacquer coatings; this is a casting head with an adjustable casting gap at its lower end through which the coating compound emerges in doses and then sinks down from there onto the material to be coated in a freely falling curtain. A known such casting head consists of two at its upper end hinged to each other jaws or shells, at the lower ends of which a knife-like bar is provided, which bars form the casting gap between them, the width or width of the casting gap by mutual approaching or removing the two casting bowls is regulated. To clean the pouring head, one of the two bowls can be folded up and the pouring head opened.

Dieser bekannte Giesskopf hat diverse schwerwiegende Nachteile. So muss z.B. die Gießspaltweite nach jedem Oeffnen des Giesskopfs neu eingestellt werden, was kritisch und mühsam ist und wobei das Resultat von der Sorgfalt des Bedienungspersonals abhängt. Ferner kann die Spaltbreiteneinstellung nur in Richtung Schliessen arretiert werden, gegen unbeabsichtigtes Oeffnen des Gießspalts besteht keine eindeutige Arretierung. Desweiteren sind die den Gießspalt bildenden Leisten (Giesslippen) bei Beschädigungen nur umständlich auszuwechseln und bedürfen dann jedesmal einer langwierigen und aufwendigen Neujustierung. Weiter kann die Gießspaltlänge nicht ohne weiteres verändert werden. Darüber hinaus hat der bekannte Giesskopf noch den Nachteil bewegter Dichtflächen an den Stirnseiten. Es sind nur geschliffene Dichtflächen vorhanden, bei denen häufig Undichtigkeiten auftreten. Einsickernder Lack härtet aus und führt bei dann erschwertem Oeffnen des Giesskopfs leicht zu Beschädigungen der geschliffenen Flächen. Schliesslich besteht der bekante Giesskopf aus einer schweren Chromstahl-Schweiss-Konstruktion und ist damit relativ teuer in der Herstellung.This well-known pouring head has several serious disadvantages. For example, the casting gap width must be reset after each opening of the casting head, which is critical and tedious and the result depends on the care of the operating personnel. Furthermore, the gap width setting can only be locked in the direction of closing, there is no clear locking against unintentional opening of the casting gap. Furthermore, the strips forming the pouring gap (pouring lips) are only laboriously replaceable in the event of damage and then require a lengthy and time-consuming readjustment each time. Furthermore, the length of the casting gap cannot be changed easily. In addition, the known casting head has the disadvantage of moving sealing surfaces on the end faces. There are only ground sealing surfaces that often leak. Seeping varnish hardens and, if the pouring head is then difficult to open, easily damages the sanded surfaces. Finally, the well-known casting head consists of a heavy chrome steel welded construction and is therefore relatively expensive to manufacture.

Aufgabe der Erfindung ist es daher, einen Giesskopf der zur Rede stehenden Art unter Vermeidung der aufgezählten Mängel der bekannten Giessköpfe so zu verbessern, dass keine Justierung des Gießspalts nach Oeffnung des Kopfs nötig ist, dass der Gießspalt leicht verändert werden kann, und dass Dichtprobleme weitestgehend reduziert werden.The object of the invention is therefore to improve a casting head of the type in question while avoiding the enumerated shortcomings of the known casting heads so that no adjustment of the casting gap after opening the head is necessary, that the casting gap can be easily changed, and that sealing problems largely be reduced.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst. Bevorzugte Ausgestaltungen ergeben sich aus den abhängigen Ansprüchen.According to the invention, this object is achieved by the characterizing features of patent claim 1. Preferred configurations result from the dependent claims.

Im folgenden wird der erfindungsgemässe Giesskopf anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Zeichnungsfigur zeigt einen Vertikalschnitt durch den Giesskopf.The casting head according to the invention is explained in more detail below on the basis of an exemplary embodiment shown in the drawing. The only drawing figure shows a vertical section through the pouring head.

Der dargestellte Giesskopf ist in einem Gestell G montiert. Er umfasst eine Grundplatte 1, zwei Giesskopfschalen 2 und 3 und ein Giesslineal 4 mit einem Gießspalt 41.The casting head shown is mounted in a frame G. It comprises a base plate 1, two casting head shells 2 and 3 and a casting ruler 4 with a casting gap 41.

Die beiden Schalen 2 und 3 sind an ihren einander zugewandten Seiten mit Ausnehmungen versehen, die zusammen zwei miteinander verbundene, langgestreckte Verteilkanäle 21 und 22 bilden. Die beiden Schalen 2 und 3 sind mittels Scharnieren 23 und 33 um zur Längserstreckung des Giesslineals 4 parallele Achsen 24 und 34 schwenkbar an der Grundplatte 1 angelenkt, so dass sie also von der gezeigten Vertikalstellung, in der der Giesskopf geschlossen ist, bis in eine Horizontallage auseinandergeklappt werden können. In dieser Lage ist der Giesskopf geöffnet und das Giesslineal 4, welches lose in einer entsprechenden Ausnehmung 12 der Grundplatte 1 angeordnet ist, kann aus dem Giesskopf entnommen bws. ausgetauscht werden.The two shells 2 and 3 are provided on their mutually facing sides with recesses which together form two elongated distribution channels 21 and 22 which are connected to one another. The two shells 2 and 3 are hinged to the base plate 1 by means of hinges 23 and 33 about axes 24 and 34 which are parallel to the longitudinal extension of the casting ruler 4, so that they therefore move from the vertical position shown, in which the casting head is closed, to a horizontal position can be unfolded. In this position, the casting head is open and the casting ruler 4, which is loosely arranged in a corresponding recess 12 in the base plate 1, can be removed from the casting head or the like. be replaced.

Zur gegenseitigen Abdichtung der beiden Schalen 2 und 3 ist eine Dichtschnur 35 vorgesehen, welche in eine umlaufende Nut 36 in der Dichtfläche 37 der Schale 3 eingelegt ist. Analog erfolgt die Abdichtung gegen das Giesslineal 4 mittels einer weiteren Dichtschnur 45 in einer umlaufenden Nut 46 in der Oberfläche des Giesslineals 4.For the mutual sealing of the two shells 2 and 3, a sealing cord 35 is provided, which is inserted into a circumferential groove 36 in the sealing surface 37 of the shell 3. Analogously, the sealing against the casting ruler 4 takes place by means of a further sealing cord 45 in a circumferential groove 46 in the surface of the casting ruler 4.

Die Zufuhr von Beschichtungsmasse erfolgt über einen Leitungsanschluss 5, der über eine Oeffnung 31 in der rechten Giesskopfschale 3 in den oberen Verteilkanal 21 mündet.The coating material is supplied via a line connection 5, which opens into the upper distribution channel 21 via an opening 31 in the right casting head shell 3.

Die beiden Giesskopfschalen 2 und 3 werden durch Spannklammern 6 zusammengehalten.The two casting head shells 2 and 3 are held together by clamps 6.

Beim erfindungsgemässen Giesskopf kann das Giesslineal, wenn es defekt oder verschmutzt ist, rasch und mühelos ausgetauscht werden, wobei jedes Justieren entfällt, da der Gießspalt im Lineal präzise fest vorgegeben ist. Die Dimensionen des Gießspalts können jederzeit problemlos durch Einlegen eines entsprechenden Giesslineals geändert werden. Da die Abdichtung der einzelnen Teile des Giesskopfs nicht an bewegten Dichtflächen erfolgt, entstehen keine Dichtprobleme. Schliesslich ist die Konstruktion des Giesskopfs einfach und kostengünstig.In the case of the casting head according to the invention, the casting ruler can be replaced quickly and effortlessly if it is defective or soiled, any adjustment being unnecessary, since the casting gap in the ruler is precisely predetermined. The dimensions of the casting gap can easily be changed at any time by inserting an appropriate casting ruler. Since the sealing of the individual parts of the casting head does not take place on moving sealing surfaces, there are no sealing problems. Finally, the design of the pouring head is simple and inexpensive.
