Description

Verfahren für beidseitige Beschichtung von Karton-, Kunststoff- oder Metallplatten und Auftragswerk zur Ausübung des Verfahrens.Process for double-sided coating of cardboard, plastic or Metal plates and commissioned work to carry out the procedure.

Die bekannten Beschichtungsmethoden für Karton-, Kunststoff-oder Metallplatten eignen sich nur für die oberseitige Beschichtung. Dies erfolgt in der regel durch einen Glesskopf zur Erzeugung eines Vorhanges für die Beschichtung der Oberseite der Platten Auftragswerke £ür die Beschichtung der Plattenunterseite, die im gleichen Arebitsgang mit einer bekannten Vorrichtung zur Beschichtung der Plattenoberseite zusammenarbeiten könnten, sind noch nicht bekannt, obwohl in neurer Zeit ein stark zunehmender Bedarf für beidseitige beschichtete Platten besteht.The known coating methods for cardboard, plastic or metal plates are only suitable for top-side coating. This is usually done through a glass head to create a curtain for coating the top of the plates commissioned works for the coating of the underside of the plate, which in the same Work cycle with a known device for coating the top of the plate work together are not yet known, although recently a strong one there is an increasing need for panels coated on both sides.

Die vorliegende Erfindung betrifft nun ein Verfahren für beidseitige Beschichtung von Karton-, Kunststoff- oder Metallplatdan. las in einer Kombination eines konventionellen Verfahrens für oberseitige Beschichtung mit einem Verfahren für unterseitige Beschichtung der Platten in einem Arbeitsgang besteht, wobei die Dicke des Filmes für die unterseitige Beschichtung regulierbar ist.The present invention relates to a method for both sides Coating of cardboard, plastic or metal platdan. read in a combination a conventional process for top-side coating with consists of a process for the underside coating of the panels in one operation, the thickness of the film for the underside coating being adjustable.

Das zur Ausübung des erfindungsgemässen Verfahrens dienende Auftragswerk weist erfindungsgemäss in der Kombination einen Giesskopf fUr die oberseitige Beschichtung in Kombination mit einer Vorrichtung fUr die unterseitige Beschichtung auf, welch letztere durch eine in ein Bad tauchende, die -Beschichtungsmasse zweckmässig mt regulierbarer Umlaufgeschwindigkeit der Plattenunterseite zuführende Beschichtungswalze gebildet ist.The commissioned work used to carry out the method according to the invention According to the invention, the combination has a casting head for the top-side coating in combination with a device for the underside coating, which the latter by a dipping into a bath, the coating mass expediently mt Coating roller feeding the underside of the plate with adjustable speed is formed.

In der Zeichnung ist eine beispielsweise Ausführungsforrn des erfindungsgemässen Auftragswerkes für beidseitige Beschichtung schematisch dargestellt.In the drawing is an example embodiment of the inventive Application work for double-sided coating shown schematically.

Das dargestellte Auftragswerk bildet eine Kombination einer Vorrichtung fUr oberneitige und einer Vorrichtung für unterseitige Beschichtung, zwischen denen die zu besehichtende Platte 1 aus Karton, Kunststoff oder Metall durch zwei Einzugswalzen 2,3 hindurchbefördert wird. Von diesen beiden Einzugswalzen 2,3 ist die obere, 3, durch Federn 4 oder andere Druckelemente belastet. Für die oberseitige Bexichlchtung dient ein Giesskopf 5 mit regulierbarer Austrittsöffnung 6 für die Bildung eines Beschichtungsmittelvorhanges 7, der sich unmittelbar nach seiner Bildung auf dle Platte oberseite legt. FUr die unterseitige Beschichtung dient eine; in ein Beschichtungsmittelbad 8 einer doppelwandigen heizbaren tianne 9 tauchende Beschlchtungswa-lze 10 aus hartem oder Weinigstens oberflächig elastischem Material, die in Pfeilrichtung sich an der Unterseite der Platte 1 abwälzend mit regulierbarer Geschwindigkeit angetrieben wird. 11 ist eine Belastungswalze, die am freien Ende eines auf der Achse 3# der oberen Einzugswalze 3 gelagerten Schwenkarmes 12 gelagert ist und durch Anheben des Schwenkarmes 12 in ihre Entlastungssteilung 11' versetzbar ist. In gesenkter Stellung der Belastungswalze 11 wird die Platte 1 gegen die Bescgichtungswalze 10- gedrückt. 13 ist eine der Auftragswalze 10 zugeordnete Rakel, welche zur Einstellung der gewünschten Filmstärke auf der Auftragswalze 10 dient. Zur Führung der beschichteten Platte 1 dienen Luftdüsen 14, 15, dieso gestellt sind, dass die Führungsluft in der Durchlaufrichtung der Platte 1 n deren Unter-und Oberseite anströmt und den Weiter transport der Platte unterstützt. Dies Führungsluft dient zugleich auch zur Abkühlung der beschichteten Plattenoberflächen.The commissioned work shown forms a combination of a device for top-side and a device for bottom-side coating, between which the to be viewed plate 1 made of cardboard, plastic or metal by two feed rollers 2.3 is conveyed through. Of these two feed rollers 2, 3 the upper, 3, loaded by springs 4 or other pressure elements. For the top-side illumination serves a casting head 5 with adjustable outlet opening 6 for the formation of a Coating agent curtain 7, which immediately after its formation on dle Plate lays on top. A coating is used for the underside of the coating; in a coating agent bath 8 a double-walled heatable fir 9 submerged coating roller 10 made of hard or at least superficially elastic material in the direction of the arrow themselves on the underside of the plate 1 rolling driven with adjustable speed will. 11 is a loading roller mounted at the free end of one on the axis 3 # of the upper feed roller 3 mounted pivot arm 12 is mounted and by lifting of the pivot arm 12 can be moved into its relief division 11 '. In lowered Position of the loading roller 11, the plate 1 is against the coating roller 10- pressed. 13 is a doctor blade assigned to the applicator roller 10, which is used for adjustment the desired film thickness on the application roller 10 is used. To guide the coated Plate 1 are used for air nozzles 14, 15, which are set so that the guide air in the direction of passage of the plate 1 n flows against the bottom and top and the Further transport of the plate supports. This guide air also serves to Cooling of the coated plate surfaces.

Anstelle der Luftdüsen 14,15 können auch zwei Abzugswalzen an das Auftragswerk angebaut sein, dit mit der Durchlaufgeschwindigkeit der Platte entsprechender Umfangsgeschwindigkeit umlaufen.Instead of the air nozzles 14,15, two take-off rollers can also be attached to the Order work to be grown, dit corresponding with the throughput speed of the plate Circumferential speed.

Die Umfangsgeschwindigkeit der Auftragswalze 10 kann gegenüber der Durchlaufgeschwindigkeit der Platte 4 reduziert sein, wodurch der Deschichtungsfilm gestreckt wird. Die Umfangsgeschwindigkeit der Einzugswalzen 2,3 sowie auch der Belastungswalze 11 ist gleich der Durchlaufgeschwindigkeit der Platte 1. Durch die beschriebene Erfindung ist es möglich, in Kombination mit einer bekannten Auftragsvorrichtung für oberseitige Beschichtung, Platten in einem einzigen Arbettsgang beidseitig zu beschichten.The peripheral speed of the application roller 10 can compared to the The passage speed of the plate 4 can be reduced, whereby the coating film is stretched. The peripheral speed of the feed rollers 2,3 as well as the Load roller 11 is equal to the passage speed of the plate 1. By the Invention described, it is possible in combination with a known application device for top-side coating, panels closed on both sides in a single step coat.
