Abstract

In order to be able to change a doctor blade whilst the web 1 is being transported with as little waste as possible, two doctor blade units 10, 12, 14; 11, 13, 15 are positioned immediately one behind the other behind an applying mechanism 4 and are alternately brought into the operating position in such a way that the one doctor blade unit 10, 12, 14 in the working position is only brought into the neutral position once the other doctor blade unit 11, 13, 15 in the neutral position is in the working position. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Verfahren zum Auftragen einer flüssigen oder pastösen Substanz auf eine Materialbahn, die an einem Auftragswerk und dann an einer Rakeleinrichtung vorbeibewegt wird. Ferner bezieht sich die Erfindung auf eine Vorrichtung zum Auftragen einer flüssigen oder pastösen Substanz auf eine Materialbahn, bestehend aus Transportmitteln für die Materialbahn, einem Auftragswerk für die Substanz und einer mehrere Rakeleinheiten aufweisenden Rakeleinrichtung.The invention relates to a method for applying a liquid or pasty substance to a material web which is moved past an application unit and then past a doctor device. Furthermore, the invention relates to a device for applying a liquid or pasty substance to a material web, consisting of transport means for the material web, an application unit for the substance and a doctor device having several doctor units.

Die Einstellung der Auftragsstärke der Substanz erfolgt bei einem bekannten Verfahren und einer bekannten Vorrichtung in der Weise, daß von mehreren zur Verfügung stehenden Rakeleinheiten eine Rakeleinheit in Arbeitsstellung gebracht wird. Die verschiedenen Rakeleinheiten sind in einer revolverartigen Rakeleinrichtung angeordnet. Um einen Rakelwechsel vorzunehmen, ist es notwendig, den Transport der Materialbahn zu stoppen, denn bei einem ununterbrochenen Transport würde in der Phase, in der die eine Rakeleinheit aus ihrer Arbeitsstellung herausgebracht wird und die neue Rakeleinheit noch nicht in Arbeitsstellung gebracht ist, eine verhältnismäßig große Materialbahnlänge ungerakelt die Rakeleinrichtung passieren und damit als Ausschuß anfallen. Durch Herabsetzen der Transportgeschwindigkeit oder Unterbrechen des Transportes während des Rakelwechsels kann diese Ausschußlänge erheblich verkürzt werden. Aber selbst bei unterbrochenem Transport weist die Materialbahn, an der Stelle, wo der Rakelwechsel stattfindet, Fehler auf. Wegen des auf eine Stelle konzentrierten Fehlers scheint der Rakelwechsel bei unterbrochenem Materialbahntransport noch am ehesten geeignet zu sein, doch bringt eine Unterbrechung des Transportes der Materialbahn andere Probleme. Das gilt in einem geringen Ausmaß auch für eine verminderte Transportgeschwindigkeit. Bei verminderter Transportgeschwindigkeit ergeben sich an der Rakeleinheit andere Auftragsbedingungen, deretwegen die Auftragsstärke sich ändert. Da die Materialbahn häufig einen Trockner durchläuft, dessen Temperatur unter Berücksichtigung der Transportgeschwindigkeit eine bestimmte Trocknungsleistung erbringt, ist es erforderlich, bei verminderter Transport­geschwindigkeit die Temperatur des Trockners entsprechend herunterzufahren. Dies ist mit erheblichem Aufwand verbunden und läßt sich nicht in einer kurzen Zeit, sondern nur allmählich erreichen. Ein Stopp des Transportes ist in der Regel nicht möglich, weil selbst bei herabgesetzter Temperatur das Temperaturniveau immer noch eine Höhe hat, die zu einer Übertrocknung der Materialbahn führt.In a known method and a known device, the application strength of the substance is set in such a way that a doctor unit is brought into the working position by several doctor units available. The various doctor units are arranged in a revolver-type doctor device. In order to change the doctor blade, it is necessary to transport the Stopping the material web, because with an uninterrupted transport, a relatively large length of material web would pass the doctoring device unswept in the phase in which the one doctor unit is brought out of its working position and the new doctor unit has not yet been brought into the working position, and would therefore be a committee. By reducing the transport speed or interrupting the transport during the doctor blade change, this reject length can be shortened considerably. But even when the transport is interrupted, the material web has errors at the point where the doctor blade change takes place. Because of the error concentrated on one spot, the doctor blade change seems to be most suitable when the material web transport is interrupted, but interrupting the transport of the material web brings other problems. To a small extent, this also applies to a reduced transport speed. If the transport speed is reduced, different application conditions result on the doctor unit, because of which the application thickness changes. Since the web of material often runs through a dryer, the temperature of which provides a certain drying capacity taking into account the transport speed, it is necessary to lower the temperature of the dryer accordingly at a reduced transport speed. This is associated with considerable effort and can not be achieved in a short time, but only gradually. It is generally not possible to stop the transport because, even when the temperature is reduced, the temperature level is still high, which leads to overdrying of the material web.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zum Auftragen einer flüssigen oder pastösen Substanz auf eine Materialbahn zu schaffen, bei dem bzw. bei der während des Rakelwechsels Auftragsfehler nicht auftreten und eventuell nachgeordnete Behandlungs­ stationen der Materialbahn während des Rakelwechsels unverändert weiterbetrieben werden können.The invention has for its object to provide a method and an apparatus for applying a liquid or pasty substance to a material web, in which or during which application errors do not occur during the doctor blade change and possibly subsequent treatment Stations of the material web can continue to be operated unchanged during the doctor blade change.

Diese Aufgabe wird erfindungsgemäß beim Verfahren dadurch gelöst, daß für einen Rakelwechsel zwei in Bewegungsrichtung hintereinander angeordnete Rakeleinheiten verwendet werden, von denen bei andauerndem Transport der Materialbahn die in Arbeitsstellung befindliche eine Rakeleinheit erst in Ruhestellung gebracht wird, wenn die in Ruhestellung befindliche andere Rakeleinheit in Arbeitsstellung gebracht ist. Vorrichtungsgemäßig wird diese Aufgabe dadurch gelöst, daß die Rakeleinrichtung zwei in Transportrichtung der Materialbahn hintereinander angeordnete und demselben Behandlungsabschnitt der Materialbahn zugeordnete Rakeleinheiten aufweist, die unabhängig voneinander an die Materialbahn anstellbar sind.This object is achieved in the method in that two doctor units arranged one behind the other in the direction of movement are used for a doctor blade change, of which during continuous transport of the material web the doctor unit located in the working position is only brought into the rest position when the other doctor unit in the rest position is in the working position brought. In terms of the device, this object is achieved in that the doctor device has two doctor units which are arranged one behind the other in the transport direction of the material web and are assigned to the same treatment section of the material web and which can be adjusted independently of one another on the material web.

Da bei der Erfindung immer eine Rakeleinheit voll in Einsatz ist, entsteht bei ununterbrochenem Materialbahntransport kein Abschnitt, der nicht gerakelt ist. Während des Rakelwechsels wird zwar ein Abschnitt doppelt gerakelt, doch führt das nicht zu einem Oberflächenfehler der abgerakelten Materialbahnseite. Da bei ununterbrochenem Transport der Materialbahn die einzelnen Rakeleinheiten in Arbeitsstellung und in Ruhestellung gebracht werden, ergeben sich selbst für die auslaufseitige Rakeleinheit keine markanten Eingriffs- und Ausgriffsstellen, vielmehr sind diese Bereiche geschliffen und treten deshalb nicht als Oberflächenfehler in Erscheinung. Da die Rakeleinheiten unabhängig voneinander anstellbar sind, ermöglicht die Rakeleinrichtung auch einen Betrieb mit zwei gleichzeitig im Einsatz befindlichen Rakeleinheiten.Since a squeegee unit is always fully used in the invention, there is no section which is not squeegee during uninterrupted material web transport. A section is squeegeeed twice during the squeegee change, but this does not lead to a surface defect on the squeegee side of the material web. Since the individual squeegee units are brought into the working position and the rest position when the material web is continuously transported, there are no striking engagement and disengagement points even for the discharge-side squeegee unit, rather these areas are ground and therefore do not appear as surface defects. Since the doctor units can be adjusted independently of one another, the doctor device also enables operation with two doctor units in use at the same time.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel schematisch darstellenden Zeichnung näher erläutert.The invention is explained in more detail below with reference to a drawing schematically illustrating an exemplary embodiment.

Eine Materialbahn 1 wird von nicht dargestellten Transportmitteln in Richtung des Pfeils 2 transportiert. Dabei wird sie mittels einer Führungsrolle 3 einem Auftragswerk 4 zugeführt, das aus einer Auftragswalze 5, einer mit der aufzutragenden Substanz gefüllten Wanne 6 und zwei Vordosiereinrichtungen 7,8 in Form von auf Spalt zur Auftragswalze 5 einstellbaren Walzen besteht. Die Auftragswalze 5 taucht mit einem Teil in die aufzutragende Substanz ein. Je nach Drehrichtung der Auftragswalze 5 ist die einer oder andere Dosiereinrichtung 7,8 angestellt. Dem Auftragswerk 4 ist eine Rakeleinrichtung 9 unmittelbar nachgeschaltet. Diese Rakeleinrichtung 9 besteht aus zwei Rakeleinheiten. Jede Rakeleinheit weist einen in einer höhenverstellbaren Aufnahme 10,11 gelagerten Rakelstab 12,13 und auf der nicht beschichteten Materialbahnseite ein höhenverstellbares Andrückblech 14,15 auf. Die beiden Rakeleinheiten 10,12,14 und 11,13,15 sind unabhängig voneinander an die Materialbahn 1 anstellbar.A material web 1 is transported in the direction of arrow 2 by transport means, not shown. It is fed by means of a guide roller 3 to an applicator unit 4, which consists of an applicator roller 5, a trough 6 filled with the substance to be applied and two pre-metering devices 7, 8 in the form of rollers that can be adjusted to the gap to the applicator roller 5. The application roller 5 is immersed in part in the substance to be applied. Depending on the direction of rotation of the application roller 5, one or the other metering device 7, 8 is employed. A squeegee device 9 is arranged directly downstream of application unit 4. This doctor device 9 consists of two doctor units. Each doctor unit has a doctor rod 12, 13 mounted in a height-adjustable receptacle 10, 11 and a height-adjustable pressure plate 14, 15 on the uncoated material web side. The two doctor units 10, 12, 14 and 11, 13, 15 can be set independently of one another on the material web 1.
