Description
Gegenstand der Erfindung ist eine Vorrichtung zum Streuen von pulverförmigen Produkten gemäss Oberbegriff des Patentanspruchs 1.The invention relates to a device for spreading powdery products according to the preamble of patent claim 1.
Auf bahnförmig hergestellten Warenbahnen, wie zum Beispiel textilen Warenbahnen, müssen für bestimmte Verwendungen der Warenbahnen oder die Veränderung von Eigenschaften derselben Pulver aufgetragen werden. Der Auftrag der Pulver muss dabei möglichst gleichmässig erfolgen. Aus dem Dokument
Anlagen innerhalb der Tanks unterschiedlich starken Drücken ausgesetzt. Dies bedeutet, dass das Pulver vor der Übertragung auf die Dosierwalze nicht gleichmässig homogenisiert ist.Installations within the tanks are subjected to different levels of pressure. This means that the powder is not evenly homogenized prior to transfer to the metering roll.
Eine Aufgabe der vorliegenden Erfindung besteht darin, eine Vorrichtung zu schaffen, mit welcher Pulver mit unterschiedlichen Eigenschaften und unterschiedlichen Qualitäten derart aufbereitet werden kann, dass eine homogene Verteilung des Pulvers auf Warenbahnen erfolgt und dass weiter Pulver mit unterschiedlichen Eigenschaften in der gewünschten Menge auftragbar sind.An object of the present invention is to provide a device with which powders with different properties and different qualities can be processed in such a way that a homogeneous distribution of the powder takes place on webs and that further powders with different properties in the desired amount can be applied.
Gelöst wird diese Aufgabe durch eine Vorrichtung gemäss den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen der Vorrichtung sind in den abhängigen Ansprüchen umschrieben.This object is achieved by a device according to the features of claim 1. Advantageous embodiments of the device are described in the dependent claims.
Durch eine Homogenisierung des aus einem Speise- und Vorratstank ausfliessenden Pulvers unmittelbar vor dessen Übertragung auf eine Dosierwalze, weisen die zur Dosierwalze gelangenden Pulverteilchen eine homogene Siebkurve auf und allenfalls vorhandene Pulverklumpen ausgeschieden werden können. Das Pulverniveau ist in allen Zonen der Dosiertanks immer gleich, unabhängig vom Pulverniveau in Speise- und Vorratstank. Mit anderen Worten, die Pulverhomogenisierung unmittelbar vor Dosierung auf die Dosierwalzen gewährleistet Homogenität und Dichte und folglich eine wesentliche Erhöhung der Sicherheit eines optimalen Pulverübertrags.
Durch das Aufteilen des aus dem Speise- und Vorratstank austretenden Pulvers auf zwei oder mehrere parallel angeordnete Dosierwalzen wird einerseits erreicht, dass, statistisch gesehen, eine höhere Gleichmässigkeit der Siebkurve und beim Auftrag auf das Werkstück erfolgt. Ausserdem kann eine Aufteilung des Pulvers auf zwei oder mehrere Dosierwalzen, die in der Horizontalen versetzt zur Ausgabeöffnung am Speisetank liegen, erfolgen und ermöglicht eine gute Zugänglichkeit der Dosierwalzen sowie der Dosiertanks. An den Dosiertanks können Deckel angelenkt sein, die den direkten Zugriff auf deren Inneres ermöglichen und insbesondere auf den Bereich, in welchem das Pulver aus den Dosiertanks auf die Dosierwalzen übertragen wird. Diese Anordnung der einzelnen Elemente der Vorrichtung ermöglicht durch eine optimale Zugänglichkeit eine einfache Wartung und Reinigung sowie einen schnellen Austausch bei Bedarf. Die Beladung und Nachfüllung des Vorratstanks ist einfach und von oben möglich. Öffnungen für die Speise- und Vorratstank-Nachfüllung sind in der Horizontalen versetzt zur Ausgabeöffnung am Speisetank liegend, und hat eine minimale Auswirkung auf die Gleichmässigkeit der Pulverzuführung an der Ausgabeöffnung. Durch eine Vibration der Wände des Vorratstanks gleitet das Pulver einwandfrei nach unten zur Ausgabeöffnung. Gleiches trifft auch zu durch das Einleiten von feinst verteilter Luft in die Dosiertanks. Das Definieren des optimalen Arbeitsbereichs erfolgt durch die Position von Schiebern zwischen der Ausgabeöffnung und dem Homogenisierer. Das Einstellen ist einfach und effizient im Vergleich zu den im Speise- und Vorratstank von bekannten Vorrichtungen.By homogenizing the powder flowing out of a feed and storage tank immediately before it is transferred to a metering roll, the powder particles reaching the metering roll have a homogeneous sieve curve and possibly any powder lumps present can be eliminated. The powder level is always the same in all zones of the dosing tanks, regardless of the powder level in the feed and storage tank. In other words, the powder homogenization immediately before Dosing on the metering rollers ensures homogeneity and density and consequently a substantial increase in the safety of an optimal powder transfer.
By dividing the emerging from the feed and storage tank powder on two or more parallel metering rollers on the one hand ensures that, statistically speaking, a higher uniformity of the screen curve and the job is carried out on the workpiece. In addition, a division of the powder on two or more metering rollers, which are offset in the horizontal to the discharge opening on the feed tank, take place, and allows good accessibility of the metering rollers and the metering tanks. Lids can be hinged to the dosing tanks, which allow direct access to their interior, and in particular to the area in which the powder is transferred from the dosing tanks to the dosing rollers. This arrangement of the individual elements of the device allows optimal accessibility easy maintenance and cleaning and a quick replacement if necessary. The loading and refilling of the storage tank is simple and possible from the top. Feed and storage tank refill openings are offset horizontally from the dispensing opening on the feed tank and have a minimal effect on the uniformity of the powder feed at the dispensing opening. By a vibration of the walls of the storage tank, the powder slides perfectly down to the discharge opening. The same applies to the introduction of finely divided air in the metering tanks. The definition of the optimum working range is made by the position of sliders between the discharge opening and the homogenizer. Adjustment is simple and efficient compared to those in the feed and storage tank of known devices.

Mit Bezugszeichen 1 ist eine Vorrichtung zum Streuen von pulverförmigen Produkten auf beispielsweise eine textile Warenbahn (Werkstück 39) bezeichnet. Diese Vorrichtung 1 ist in einem Gehäuse 3 eingesetzt, welches durch beispielsweise vier Profilrohre 5 und Wände 4 begrenzt wird. Die Profilrohre 5 tragen einen im Querschnitt V-förmigen Speise- und Vorratstank 7 für die Aufnahme von pulverförmigen Produkten, wie zum Beispiel Klebstoffgranulat, medizinischer Puder oder saugfähiges Granulat, Zement, Bentonit oder andere pulverförmige Produkte. Am unteren Ende des Speise- und Vorratstanks 7 ist eine Ausgabeöffnung 9 ausgebildet, durch welche das im Speise- und Vorratstank 7 befindliche Pulver 11 unter der Wirkung der Schwerkraft austreten kann. Vorzugsweise ist mindestens an einer der beiden Seitenwände 13 zusätzlich ein Vibrator 15 befestigt, um die mindestens eine Seitenwand 13 in Schwingung zu versetzen, damit das im Speise- und Vorratstank 7 befindliche Pulver 11 beim Nach-unten-Gleiten begünstigt wird.Reference numeral 1 designates an apparatus for spreading pulverulent products onto, for example, a textile material web (workpiece 39). This device 1 is inserted in a
Unterhalb der Ausgabeöffnung 9 ist ein Homogenisierer 17 angeordnet, zum Beispiel ein Sieb oder ein Lochblech, das durch geeignete Mittel in Schwingung versetzt das austretende Pulver nach unten austreten lässt und mit welchem allfällig verklumptes Pulver oder zu grosse Pulverteile zurückgehalten und ausgeschieden werden können.Below the dispensing opening 9, a
Zwischen Ausgabeöffnung 9 und dem Homogenisierer 17 können Schiebebleche 45 angeordnet sein. Diese erlauben es, auf einfache Weise in unterschiedlichen Positionen die Weite (Breite) oder Grösse der Ausgabeöffnung 9 und damit den Arbeitsbereich der Vorrichtung zu bestimmen.Between the discharge opening 9 and the
Unterhalb des Homogenisierers 17 liegt in der Ausgestaltung der Erfindung mit zwei oder mehreren Dosierwalzen 19 ein Keil 21 oder mehrere Keile 21, welche den Pulverstrom auf zwei oder mehrere Dosierwalzen 19 umlenken. Die beiden Schenkelflächen 23 des Keils oder der Keile 21 bilden den Boden von darüber angeordneten Dosiertanks 25.Below the
In einer bevorzugten Ausgestaltung der Erfindung ist der Keil 21 oder sind die Keile 21 aus einem porösen Material, z.B. einem gesintertes Material hergestellt, durch welches Pressluft in das Pulver 11 in den Dosiertank 25 eingeleitet werden kann. Durch die eingeleitete Luft (air) wird durch die Fluidisierung des Pulvers 11 das Gleiten das Gleiten desselben auf den Schenkelflächen 23 des Keils 21 wesentlich begünstigt. Die unteren Kanten der Schenkelflächen 23 liegen in geringem Abstand zu den Oberflächen der beiden Dosierwalzen 19.In a preferred embodiment of the invention, the wedge 21 or wedges 21 are made of a porous material, e.g. a sintered material prepared by which compressed air can be introduced into the
Die Dosierwalzen 19 sind horizontal relativ zur Ausgabeöffnung 9 verschiebbar. Dies ermöglicht ein stabiles Pulverniveau über den Dosierwalzen 19 im Dosiertank 25 und dadurch eine hohe Homogenität der Pulververteilung.The
Im Wesentlichen spiegelbildlich zu den Schenkelflächen 23 des Keils 21 sind Seitenwände 27 der Dosiertanks 25 ausgebildet. Die Seitenwände 27 sind an den unten liegenden Profilrohren 5 befestigt. Ebenfalls an den unten liegenden Profilrohren 5 sind sogenannt schwimmende Rakel 29 befestigt, mit welchen in bekannter Weise das von oben aus den beiden Dosiertanks 25 zufliessende Pulver 11 auf die Oberflächen der Dosierwalzen 19 übertragen wird. Die Rakel 29, die am Rahmen der Vorrichtung 1, das heisst den Rohren 5 befestigt sind, werden von einer Mehrzahl von elastischen Elementen 44 gehalten (
Zur gelegentlichen Reinigung der Oberflächen der Dosierwalzen 19 sind weiter an den Profilrohren 5 Ausputzvorrichtungen 31 angeordnet. Deren Aufbau wird nicht näher erläutert.For occasional cleaning of the surfaces of the
Die beiden Dosiertanks 25 sind oben durch Deckel 33 verschliessbar. Die Deckel 33 sind an Profilrohren 35 befestigt, welche die Seitenwände 13 des Speise- und Vorratstanks 7 tragen.The two
Nachfolgend wird die Funktionsweise der Vorrichtung 1 näher erläutert. Durch eine Öffnung 37 an der Oberseite des Speise- und Vorratstanks 7 wird das benötigte und auf die Applikation angepasste Pulver 11 in den Speise- und Vorratstank 7 eingefüllt. Diese Öffnungen 37 sind seitlich des Speise- und Vorratstanks 7 angeordnet. Dadurch hat das Nachfüllen des Speise- und Vorratstanks 7 bei laufendem Betrieb nur einen minimalen Einfluss auf die Pulverbewegung durch die Ausgabeöffnung 9. Auf gleiche Weise erfolgt das Nachfüllen während des Betriebs der Vorrichtung 1. Das Nachfüllen kann manuell oder über ein Rohrsystem 43 automatisch erfolgen. Begünstigt durch die Vibrationen, erzeugt durch den mindestens einen Vibrator 15, gleitet das Pulver 11 entlang den Seitenwänden 13 zur Ausgabeöffnung 9 im Vorratstank 7 und von dort in den Homogenisierer 17 beziehungsweise auf das Sieb des Homogenisierers 17. Die effektive Arbeitsbreite des Pulverauslassens kann durch die Position des oder der Schiebebleche 45 eingestellt werden. Das Verschieben der Schiebebleche 45 ist einfach und folglich auch das Einstellen der Arbeitsbreite bzw. der Breite des Pulveraustrags. Der Keil 21 der direkt unterhalb des Homogenisierers 17 angeordnet ist, teilt den Pulverstrom in zwei oder mehrere Richtungen. Diese Pulverströme füllen nun die Dosiertanks 25. Um auch hier den Abfluss des Pulvers 11 zu begünstigen, kann Luft zur Fluidisierung durch den Keil 21 beziehungsweise durch dessen Schenkelflächen 23 in das Pulver 11 eingeblasen werden. Das durch die Schwerkraft nach unten fliessende Pulver in den Dosiertanks 25 gelangt auf die Oberflächen der beiden Dosierwalzen 19 und wird durch die Rakeln 29 gleichmässig verteilt. In bekannter Weise führen die beiden Dosierwalzen 19 nun das Pulver 11 vom Scheitel der Dosierwalzen 19, wo das Pulver 11 zugeführt wird, in deren seitlich des Scheitels liegenden Bereich, von wo das Pulver 11 in freiem Fall auf ein Werkstück 39, z.B. auf eine textile Warenbahn fällt. Das Werkstück 39 wird durch geeignete Transportmittel, z.B. ein Transportband (nicht dargestellt) in Richtung des Pfeils P unter den beiden Dosierwalzen 19 vorbeigeführt.The mode of operation of the device 1 will be explained in more detail below. Through an
