Abstract

In a process for the application of liquid, pasty or plastic substances, in particular thermoplastics, to a substrate (1), these substances are melted and transferred, via a coating head (5), through a perforated cylinder (3) to the substrate (1). The perforated cylinder (3), together with a counterpressure roll (4), forms a coating nip (2) downstream of which the substrate (1) is taken off, partly looping over a roll (9). The spacing (a) between the rotational shafts (A, B) of the counterpressure roll (4) and cylinder (3) is smaller than a sum of the radii (r1 and r2). The counterpressure roll (4) moreover consists of a flexible material, so that a contact surface (8) of the coating head (5), for forming a coating nip (2), has a curvature whose radius corresponds approximately to that of the cylinder (3).

Description

Die Erfindung betrifft ein Verfahren zum Auftragen von flüssigen, pastösen oder plastischen Substanzen, insbesondere von Thermoplasten, auf ein Substrat, wobei die Substanz aufgeschmolzen, beheizt und durch einen perforierten Zylinder auf das Substrat aufgebracht wird, an welchem es über eine Strecke haftet, bevor es abgezogen wird, sowie eine Vorrichtung hierfür.The invention relates to a method for applying liquid, pasty or plastic substances, in particular thermoplastics, to a substrate, the substance being melted, heated and applied to the substrate by a perforated cylinder to which it adheres over a distance before it is withdrawn, and a device therefor.

Aus der DE-OS 36 38 307 ist ein derartiges Verfahren und eine derartige Vorrichtung bekannt, wobei dem Düsenmund im Innern des Metallzylinders eine Luftdüse nachfolgt, welche zum Metallzylinder hin einen von Lippen begrenzten Düsenspalt ausbildet. Weiterhin sind außerhalb des Metallzylinders Kühl- bzw. Heizstrecken angeordnet, bevor das Substrat ein Kalanderwalzenpaar durchläuft.Such a method and such a device is known from DE-OS 36 38 307, the nozzle mouth in the interior of the metal cylinder being followed by an air nozzle which forms a nozzle gap bounded by lips towards the metal cylinder. Furthermore, cooling or heating sections are arranged outside the metal cylinder before the substrate passes through a pair of calender rolls.

Dabei hat sich in der Praxis herausgestellt, daß bei unterschiedlichen Temperaturen der Beschichtungssubstanz ein unterschiedlicher Zug auf das Substrat ausgeübt werden muß, um das Substrat von dem perforierten Metallzylinder abzuheben.It has been found in practice that at different temperatures of the coating substance, a different pull must be exerted on the substrate in order to lift the substrate from the perforated metal cylinder.

Aufgabe der vorliegenden Erfindung ist es, eine Verbesserung des Aufbringens der Beschichtungssubstanz sowie der Handhabung des Beschichtungskopfes beim Abschalten der Vorrichtung zu gewährleisten.The object of the present invention is to ensure an improvement in the application of the coating substance and in the handling of the coating head when the device is switched off.

Zur Lösung dieser Aufgabe führt, daß der Abstand zwischen den Drehachsen von Gegendruckwalze und Zylinder kleiner ist als die Summe der Radien, daß die Gegendruckwalze aus einem flexiblen Werkstoff besteht und daß eine Anlagefläche des Beschichtungskopfes zur Bildung des Beschichtungsspaltes eine Krümmung aufweist, deren Radius etwa demjenigen des Zylinders entspricht.The solution to this problem is that the distance between the axes of rotation of the counter-pressure roller and cylinder is smaller than the sum of the radii, that the counter-pressure roller consists of a flexible material and that a contact surface of the coating head to form the coating gap has a curvature, the radius of which is approximately that of the cylinder.

Hierdurch wird ein flächiger Beschichtungsspalt gebildet, so daß sich Dichtungslippen erübrigen. Ferner wird auch durch den flächigen Druck die Benetzung des Substrates mittels der Substanz verbessert.As a result, a flat coating gap is formed, so that sealing lips are unnecessary. Furthermore, the wetting of the substrate by means of the substance is also improved by the flat pressure.

Zur Verbesserung des Gebrauchs des Beschichtungskopfes beim Abschalten der Vorrichtung dient, daß in die Zuleitung für die Substanz eine Vakuumpumpe eingeschaltet ist. Bevorzugt wird diese Vakuumpumpe über ein Drei-Wege-Ventil mit dem Beschichtungskopf verbunden und dann in Gang gesetzt, wenn die Vorrichtung abgeschaltet wird. Hierdurch wird dann der Beschichtungskopf entleert und es kommt zu keinem Nachtropfen der Substanz.To improve the use of the coating head when the device is switched off, a vacuum pump is switched on in the feed line for the substance. This vacuum pump is preferably connected to the coating head via a three-way valve and then started when the device is switched off. This then empties the coating head and there is no dripping of the substance.

In einer weiteren bevorzugten Ausführungsform der Erfindung besteht der Beschichtungskopf aus Teilsegmenten, welche miteinander verbunden sind. Die Verbindung kann beispielsweise über entsprechende Zuganker erfolgen. Hierdurch wird die Breite des Beschichtungskopfes bestimmt bzw. verändert und auch eine streifenweise Beschichtung möglich, indem ein oder mehrere Teilsegmente keinen Mündungsspalt für eine Beschichtungssubstanz besitzen. Ferner ist auch eine Zufuhr unterschiedlicher Beschichtungssubstanzen zu einzelnen Teilsegmenten möglich.In a further preferred embodiment of the invention, the coating head consists of sub-segments which are connected to one another. The connection can be made, for example, via appropriate tie rods. As a result, the width of the coating head is determined or changed, and coating in strips is also possible in that one or more sub-segments do not have an orifice gap for a coating substance. Furthermore, it is also possible to supply different coating substances to individual sub-segments.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in

  • Figur 1 eine schematische Darstellung einer erfindungsgemäßen Vorrichtung zum Auftragen von flüssigen, plastischen oder pastösen Substanzen auf ein Substrat, teilweise als Blockschaltbild, teilweise im Querschnitt dargestellt;
  • Figur 2 eine schematische Draufsicht auf einen Beschichtungskopf entsprechend Figur 1.
Further advantages, features and details of the invention emerge from the following description of preferred exemplary embodiments and with reference to the drawing; this shows in
  • Figure 1 is a schematic representation of an inventive device for applying liquid, plastic or pasty substances to a substrate, partly as a block diagram, partly shown in cross section;
  • FIG. 2 shows a schematic top view of a coating head corresponding to FIG. 1.

Ein zu beschichtendes Substrat 1 läuft von einer nicht näher gezeigten Vorratswalze in einen Beschichtungsspalt 2 ein. Dieser Beschichtungsspalt 2 wird von einem perforierten Zylinder 3, insbesondere einem Metallzylinder, und einer Gegendruckwalze 4 gebildet. Die Gegendruckwalze 4 besteht aus elastischem Material. Der Abstand a zwischen der Drehachse A der Gegendruckwalze 4 und der Drehachse B des Zylinders 3 ist kleiner als die Summe der beiden Radien r1 und r 2. Hierdurch wird die elastische Gegendruckwalze 4 im Bereich des Beschichtungsspaltes 2 durch den Andruck des Zylinders 3 verformt. Diese Verformung ist natürlich auch dann gegeben, wenn im engeren Sinn ohne Substrat kein Beschichtungsspalt zwischen Zylinder 3 und Walze 4 gebildet ist.A substrate 1 to be coated runs into a coating gap 2 from a supply roller (not shown in more detail). This coating gap 2 is formed by a perforated cylinder 3, in particular a metal cylinder, and a counter-pressure roller 4. The counter-pressure roller 4 is made of elastic material. The distance a between the axis of rotation A of the counter-pressure roller 4 and the axis of rotation B of the cylinder 3 is smaller than the sum of the two radii r 1 and r 2 . As a result, the elastic counter-pressure roller 4 is deformed in the region of the coating gap 2 by the pressure of the cylinder 3. This deformation is of course also given if, in the narrower sense, no coating gap is formed between cylinder 3 and roller 4 without a substrate.

Im Bereich des Beschichtungsspaltes 2 drückt vom Inneren des Zylinders 3 her ein Beschichtungskopf 5 gegen die Innenfläche 6 des Zylinders 3.In the area of the coating gap 2, a coating head 5 presses against the inner surface 6 of the cylinder 3 from the inside of the cylinder 3.

Dabei ist um einen Mündungsspalt 7 des Beschichtungskopfes 5 eine Anlagefläche 8 beidseits des Mündungsspaltes 7 ausgebildet, wobei diese Anlagefläche zur Innenfläche 6 hin eine Krümmung mit etwa einem Radius r2 aufweist. Durch diese Anordnung entsteht ein Bereich des Beschichtungsspaltes 2, welcher durch die Anlagefläche 8 und die Gegendruckwalze 4 abgedichtet ist. Es erübrigen sich beispielsweise Dichtlippen um den Mündungsspalt 7.In this case, a contact surface 8 is formed on both sides of the opening gap 7 around an opening gap 7 of the coating head 5, this contact surface facing the inner surface 6 having a curvature with a radius r 2 . This arrangement creates an area of the coating gap 2 which is sealed by the contact surface 8 and the counter-pressure roller 4. For example, sealing lips around the mouth gap 7 are unnecessary.

Nach dem Beschichtungsspalt 2 läuft das Substrat 1 noch über eine gewisse Strecke auf dem Zylinder 3, hebt dann ab und umschlingt eine Walze 9.After the coating gap 2, the substrate 1 still runs a certain distance on the cylinder 3, then lifts off and loops around a roller 9.

Dem Mündungsspalt 7 ist in dem Beschichtungskopf 5 eine Hauptkammer 15 vorgeschaltet, welche über entsprechende Anschlußkanäle 16 bzw. Zuleitung 17 mit einer nicht näher dargestellten Quelle für aufgeschmolzenes Beschichtungsmaterial in Verbindung steht. Erfindungsgemäß soll in die Leitung 17 ein Drei-Wege-Ventil 18 eingeschaltet sein, über welches wechselweise die Leitung 17 mit der Beschichtungsmaterialquelle oder mit einer Vakuumpumpe 19 verbunden werden kann.A main chamber 15 is connected upstream of the orifice gap 7 in the coating head 5 and is connected via a corresponding connection channel 16 or feed line 17 to a source (not shown in more detail) for molten coating material. According to the invention, a three-way valve 18 is to be switched on in line 17, via which line 17 is alternately connected to the coating material source or to a vacuum pump 19 can.

Soll beispielsweise die Zugabe von Beschichtungsmaterial abgeschaltet werden, so erfolgt ein Umschalten durch das Drei-Wege-Ventil auf die Vakuumpumpe 19, über welche überflüssiges Beschichtungsmaterial aus der Hauptkammer 15 bzw. dem Mündungsspalt 7 abgezogen wird.If, for example, the addition of coating material is to be switched off, the three-way valve switches over to the vacuum pump 19, via which excess coating material is withdrawn from the main chamber 15 or the mouth gap 7.

Als Vakuumpumpe kommt beispielsweise auch ein einfacher Zylinder in Frage, in welchem ein Kolben eine Arbeitskammer ausbildet. Durch Zurückziehen des Kolbens wird der Arbeitsraum vergrößert und Beschichtungsmaterial angesaugt. Beim Anfahren wird dieses Material zuerst herausgepreßt. Hierdurch wird ein Nachtropfen von Beschichtungsmaterial aus dem Mündungsspalt 7 wirksam vermieden.A simple cylinder, for example, in which a piston forms a working chamber can also be used as the vacuum pump. By pulling back the piston, the working space is enlarged and coating material is sucked in. When starting up, this material is first pressed out. This effectively prevents coating material from dripping out of the mouth gap 7.

Eine weitere Verbesserung der vorliegenden Erfindung ist darin zu sehen, daß der Beschichtungskopf 5, wie in Figur 2 gezeigt, mehrteilig ausgebildet ist. Im vorliegenden Ausführungsbeispiel besteht der Beschichtungskopf 5 aus den Teilsegmenten 5a, 5b und 5c. Diese Teilsegmente sind untereinander mittels entsprechender Zuganker verbunden und ggfs. gegeneinander abgedichtet. Auf diese Weise kann die Breite b des Beschichtungskopfes 5 bestimmt und verändert werden. Ferner kann ein Teilsegment, beispielsweise 5b keinen Mündungsspalt 7 besitzen, so daß eine streifenweise Beschichtung vorgenommen wird.A further improvement of the present invention can be seen in the fact that the coating head 5, as shown in FIG. 2, is constructed in several parts. In the present exemplary embodiment, the coating head 5 consists of the sub-segments 5a, 5b and 5c. These sub-segments are connected to one another by means of corresponding tie rods and, if necessary, sealed off from one another. In this way, the width b of the coating head 5 can be determined and changed. Furthermore, a sub-segment, for example 5b, may not have an orifice gap 7, so that coating is carried out in strips.
