Abstract

In paint application devices which operate according to the infusion principle, the liquid flowing over an overflow weir is retained in an upstream liquid reservoir. Said liquid then flows over the overflow weir and over the subsequent guiding surface. In the event of high application quantities of 50 L/m/Min and more, there is a risk that the liquid layer may detach itself from the guiding surface in the region of the overflow weir. Said overflow weir is thus enveloped over the working width, a height-adjustable deviation block with a downwardly pointing edge determining the volume running over the guiding surface.

Description

VORRICHTUNG ZUM AUFBRINGEN EINER ÜBER DIE ARBEITSBREITE GLEICHMASSIG DICKEN FLÜSSIGKEITSSCHICHT AUF EINE WARENBAHNDEVICE FOR APPLYING A WORKING WIDE SAME LIQUID LIQUID LAYER TO A TRACK

Die Erfindung bezieht sich auf eine Vorrichtung zum Aufbringen einer über die Arbeitsbreite gleichmäßig dicken, laminar fließenden Flüssigkeitsschicht großer Breite auf eine kontinuierlich vorbewegte Warenbahn mit einem Flüssigkeitsvorratsraum, der einerseits durch eine schräg zur Horizontalen aufwärts gerichtete und über die Arbeitsbreite sich erstreckende Stauwand begrenzt ist, der in Fließrichtung der Flüssigkeit ein Überlaufwehr sowie eine sich an das Überlaufwehr anschließende Leitfläche folgt, von deren unterm Rand der übergelaufene Flüssigkeitsfilm auf die Warenbahn abläuft, und der vorzugsweise andererseits mit Abstand zur Stauwand darüber durch eine Gegenstauwand begrenzt ist, wobei der Flüssigkeitsvorratsraum einen Flüssigkeitszulaufbereich aufweist,The invention relates to a device for applying a uniformly thick over the working width, laminar flowing liquid layer of large width on a continuously advancing web with a liquid reservoir, which is bounded on the one hand by an obliquely to the horizontal upward and over the working width extending stowage, the an overflow weir follows in the direction of flow of the fluid and a guide surface adjoins the overflow weir, from the lower edge of which the overflowed liquid film drains onto the material web, and which is preferably delimited at a distance from the stowage wall by an opposing stowage wall, the liquid reservoir having a fluid inlet region,

Eine Vorrichtung dieser Art ist durch die EP-A-0 753 357 bekannt. Sie zeichnet sich durch einen gleichmäßigen Flüssigkeitsauftrag auf die vorlaufende Warenbahn aus. Dies gilt zunächst für jede Menge einer aufzutragenden Farbe. Es hat sich aber gezeigt, dass bei größeren Auftragsmengen, dass bei notwendig dicken Flüssigkeitsschichten der Druck der Zuführpumpen so groß sein muss, dass sich an dem Überlaufwehr eine Abrisskante bildet. Die Flüssigkeit schießt über das Überlaufwehr hinweg, ein gleichmäßiger Flüssigkeitsauftrag über die Arbeitsbreite der Leitfläche ist nicht mehr möglich. Dieses Problem der immer größer werdenden Kinematik gegenüber der wirksamen Schwerkraft wurde bei Auftragsmengen zwischen 50 und 200 l/m/Min festgestellt. Selbstverständlich gilt dies auch bei noch höheren Auftragsmengen. Der Erfindung liegt die Aufgabe zugrunde, eine Auftragsvorrichtung anfangs genannter Art derart weiterzuentwickeln, dass jedes Volumen pro Zeiteinheit gleichmäßig verteilt über die Arbeitsbreite aufgetragen werden kann.A device of this kind is known from EP-A-0 753 357. It is characterized by a uniform application of liquid to the leading web. This applies initially to any amount of a color to be applied. However, it has been found that for larger application quantities, the thickness of the feed pumps must be so great that the overflow weir forms a spoiler edge. The liquid shoots over the overflow weir, a uniform liquid application over the working width of the guide surface is no longer possible. This problem of ever-increasing kinematics versus effective gravity has been found at application rates of between 50 and 200 l / m / min. Of course, this also applies to even higher order quantities. The invention has for its object to further develop an applicator device initially mentioned such that each volume per unit time can be applied evenly distributed over the working width.

Zur Lösung der gestellten Aufgabe ist nach der Erfindung vorgesehen, dass dem Überlaufwehr oder der Leitfläche über die ganze Länge der Arbeitsbreite ein die Durchflussmenge begrenzender Umlenkblock mit Abstand zugeordnet ist. Damit ist erreicht, dass die in Richtung des Überlaufwehres vorschießende Flüssigkeit durch den Umlenkblock gebremst, umgelenkt und damit gezwungen wird, in einer von dem justierbaren Umlenkblock vorausbestimmten Dicke an der Leitfläche herabzufließen.To achieve the object is provided according to the invention that the overflow weir or the guide surface over the entire length of the working width, a flow rate limiting deflection block is assigned at a distance. This ensures that the advancing in the direction of the overflow weir fluid is braked by the Umlenkblock, deflected and thus forced to flow down in a predetermined by the adjustable deflection block thickness of the guide surface.

Nach der EP-A-0 753 357 ist innerhalb des Flüssigkeitsvorratsraumes ein Verteilkamm angeordnet, der die zum Überlaufwehr fließende Flüssigkeit beruhigend, vergleichmäßigend beeinflussen soll. Im Zusammenhang mit dem nach der Erfindung vorgesehenen, den Durchflussbereich in der Schichtdicke über die Arbeitsbreite begrenzenden Umlenkblock ist es zweckmäßig, auch die freien Enden dieses Kamms kurvenförmig auszubilden, derart dass sie sich über die Überlaufkante bis hin zur Ebene der Leitfläche erstrecken.According to EP-A-0 753 357 a distribution comb is arranged within the liquid storage space, which is intended to calmingly, comparatively affect the liquid flowing to the overflow weir. In connection with the invention provided, the flow area in the layer thickness over the working width limiting Umlenkblock, it is expedient to form the free ends of this comb curved so that they extend over the overflow edge to the level of the guide surface.

In der Zeichnung ist eine Vorrichtung der erfindungsgemäßen Art beispielhaft dargestellt. Es zeigen:In the drawing, a device of the type according to the invention is exemplified. Show it:

Fig. 1 einen Schnitt quer durch den Balken des Flüssigkeitsauftraggerätes mit dem am Balken befestigen Umlenkblock,1 shows a section across the bar of the liquid applicator with the deflecting block attached to the beam,

Fig. 2 die Ansicht mit dem Querschnitt eines innerhalb des Flüssigkeitsvorratsraumes angeordneten Verteilkamms undFig. 2 is the view with the cross section of a disposed within the liquid storage space distribution comb and

Fig. 3 der Verteilkamm in perspektivischer Darstellung.Fig. 3, the distribution comb in a perspective view.

Die Flüssigkeitsauftragsvorrichtung gemäß der Fig. 1 besteht aus einem winkelförmigen Balken 1 , dessen 90° umfassendes Überlaufwehr 2 nach oben ausgerichtet ist. Der eine schräg nach oben zum Überlaufwehr 2 hin verlaufende Schenkel ist die Stauwand 3, an die sich nach dem Überlaufwehr 2 die Leitfläche 4 anschließt. Über diese Leitfläche fließt gleichmäßig verteilt der aufzutragende Flüssigkeitsfilm The liquid application device according to FIG. 1 consists of an angle-shaped beam 1, whose 90 ° overflow weir 2 is oriented upwards. The one obliquely upwards to the overflow weir 2 extending leg is the stowage wall 3, which is followed by the overflow weir 2, the guide surface 4. The liquid film to be applied flows uniformly distributed over this guide surface

oder -schicht, die nach Ablauf von der unteren Kante 5 der Leitfläche 4 auf die Warenbahn 6 fließt.or layer, which flows after expiration of the lower edge 5 of the guide surface 4 on the web 6.

Auf der der Stauwand 3 des Balkens 1 gegenüberliegenden Seite ist ein massiver Körper 7, der Flüssigkeitsverteilkörper, flüssigkeitsdicht befestigt, der in dem dem Überlaufwehr 2 zugeordneten Bereich einen Flüssigkeitsvorratsraum 8 aufweist. Dieser Flüssigkeitsvorratsraum 8 ist gemäß Fig. 1 zunächst begrenzt durch die Stauwand 3 und die mit Abstand darüber angeordnete, parallel verlaufende Gegenstauwand 9 des Flüssigkeitsverteilkörpers.On the stagnation wall 3 of the beam 1 opposite side is a solid body 7, the liquid distribution body, liquid-tightly secured, which has a liquid storage space 8 in the region assigned to the overflow weir 2. According to FIG. 1, this liquid storage space 8 is initially limited by the stowage wall 3 and the spaced-apart, parallel counter-stowing wall 9 of the liquid-distributing body.

An dem dem Überlaufwehr 2 gegenüberliegenden Ende des Flüssigkeitsvorratsraumes 8 ist der Flüssigkeitszulaufbereich 10 angeordnet. Er besteht aus einer Vielzahl von quer durch den Flüssigkeitsverteilkörper 7 sich erstreckenden Bohrungen 11, die dann am unteren Ende des Flüssigkeitsvorratsraumes 9 die Flüssigkeitszuflußöffnungen 12 haben.At the opposite end of the overflow weir 2 of the liquid reservoir 8, the liquid inlet region 10 is arranged. It consists of a plurality of transversely through the Flüssigkeitsverteilkörper 7 extending holes 11, which then have the Flüssigkeitszuflußöffnungen 12 at the lower end of the liquid storage space 9.

An dem gegenüberliegenden, oberen Ende der Bohrungen 11 ist eine Flüssigkeitsverteileinrichtung 13 angeordnet, wie sie in der DE 40 26 198 A1 beschrieben ist.At the opposite, upper end of the bores 11, a liquid distribution device 13 is arranged, as described in DE 40 26 198 A1.

Normalerweise genügt es, wenn der durch die Bohrungen 11 geförderte Flüssigkeitsstrom zum Überlaufwehr 2 vor- und von dort über die Leitfläche 4 abfließt. Nur bei großen Auftragsmengen von 50 l/m/Min und mehr besteht die Gefahr, dass die über die Arbeitbreite der Auftragsvorrichtung verteilte Flüssigkeit eine so hohe Zuflussgeschwindigkeit aufweist, dass die Kinematik die Schwerkraft an dem Überlaufwehr 2 übersteigt. Bei diesen großen Auftragsmengen kann es passieren, dass die Flüssigkeit regelrecht über das Überlaufwehr 2 hinwegschießt. Um dies zu vermeiden, ist ein die zufließende Flüssigkeit zwingender Flüssigkeitsumlenkblock 14 im Bereich des Überlaufwehres über die Länge der Auftragsvorrichtung angebracht. Er weist eine untere Kante 15 auf, die mit der Leitfläche 4 einen Durchflussspalt 16 bildet. Damit wird das zufließende Flüssigkeitsvolumen gezwungen den Weg über die Überlaufkante 2 zu gehen, es staut sich vor dem Durchflussspalt 16 und fließt dann in der gewünschten Dicke mit dem gewünschten Volumen gleichmäßig über die Breite der Auftragsvorrichtung, über die Leitfläche 4 auf die Ware 6 ab. Selbstverständlich ist der Flüssigkeitsumlenkblock 14 in der Höhe z. B. mittels am Körper 7 angreifender Schrauben 17 einstellbar.Normally, it is sufficient if the funded through the holes 11 liquid flow to the overflow weir 2 upstream and flows from there via the guide surface 4. Only with large application quantities of 50 l / m / min and more is there the danger that the liquid distributed over the working width of the application device has such a high inflow velocity that the kinematics exceeds the gravity at the overflow weir 2. With these large order quantities, it can happen that the liquid literally shoots over the overflow weir 2. In order to avoid this, a liquid deflecting block 14, which forces the inflowing liquid, is mounted in the region of the overflow weir over the length of the applicator. It has a lower edge 15, which forms a flow gap 16 with the guide surface 4. Thus, the inflowing liquid volume forced to go the way over the overflow edge 2, it accumulates in front of the flow gap 16 and then flows in the desired thickness with the desired volume evenly across the width of the applicator, via the guide surface 4 on the goods 6. Of course, the Flüssigkeitsumlenkblock 14 in height z. B. by means of attacking the body 7 screws 17 adjustable.

In dem Flüssigkeitsvorratsraum 8 ist ein Verteilkamm 18 eingebracht, dessen untere Befestigungsschiene 19 den Flüssigkeitsvorratsraum 8 nach unten verschließt. Es ist zweckmäßig, die freien Enden 20 des Verteilkamms 18 bogenförmig nach unten zu bilden, wie es aus der Fig. 2 und 3 hervorgeht. Die Enden liegen mit ihrem Bogen auf dem Überlaufwehr 2 auf. Diese bogenförmige Ausbildung der Kammenden 21 führt die Flüssigkeit um das Überlaufwehr 2 und beeinflusst die Führung der Auftragsflüssigkeit auf die Leitfläche 4. In the liquid storage space 8, a distribution comb 18 is introduced, the lower mounting rail 19 closes the liquid reservoir 8 down. It is expedient to form the free ends 20 of the distributor comb 18 in an arcuate manner downward, as can be seen from FIGS. 2 and 3. The ends lie with their bow on the overflow weir 2. This arcuate design of the comb ends 21 guides the liquid around the overflow weir 2 and influences the guidance of the application liquid onto the guide surface 4.
