Abstract

An arrangement for dosing with a blade, in coating machines or similar, onto a running web of paper or cardboard carried by a roll in or with the arrangement. The blade is forced by means of a hold-down or several hold-down sections on the roll respectively the web. A transmitter transmits light, notably laser light. The blade features in the area between the contact line of the hold-down on it, and its contact line on the roll respectively the web, on its side away from the roll, at least one light-reflecting layer for reflection of the light ray directed by the transmitter at the layer. A receiver registers the position or angle of the ray reflected upon it by the light-reflecting layer of the blade. A controller is provided for controlling, dependent on the position signal of the receiver for the reflected light ray, the angular position of the blade, notably in its area between the contact line of the hold-down or the hold-down section and the roll.

Description

Die Erfindung betrifft eine Anordnung zum Dosieren entsprechend dem Oberbegriff des Patentanspruchs 1. Die erfindungsgemäße Dosiereinrichtung verwendet eine sogenannte Streichklinge in Streichanlagen, wobei dieser Streichklinge eine Zufuhreinrichtung für die Streichmasse unmittelbar oder in einiger Entfernung von vielleicht 30-50 cm entlang dem Umfang einer die Bahn aus Papier oder Karton führenden Walze zugeordnet sein kann. Es kann auch so sein, daß die Papierbahn erst später auf die Walze aufläuft, so daß zunächst eine Beschichtung des bloßen Walzenmantels erfolgt und erst später eine Übertragung der Streichmasse von dem Walzenmantel auf die Papierbahn vorgenommen wird.The invention relates to an arrangement for dosing according to the preamble of claim 1. The dosing device according to the invention uses a so-called doctor blade in coating systems, this doctor blade being a feed device for the coating compound directly or at a distance of perhaps 30-50 cm along the circumference of the web Paper or cardboard leading roller can be assigned. It may also be the case that the paper web only runs onto the roller later, so that firstly the bare roller shell is coated and the coating slip is only transferred later from the roller shell to the paper web.

Eine gattungsbildende Einrichtung ist bekannt aus der EP-A 04 26 980. In dieser Anmeldung ist z.B. auch eine Meßeinrichtung mit einem Sender beschrieben, der Licht emittiert, welches von einer lichtempfindlichen Empfängeranordnung, z.B. in Form einer Dioden-Reihenanordnung oder einer CCD-Kamera registriert wird. Das Ausgangssignal dieser Anordnungen wird dann weiterverarbeitet, um die Winkellage der Klinge in Bezug auf den Walzenumfang im Anlagepunkt der Klinge an demselben einzustellen. Alle in dieser Anmeldung beschriebenen Meßeinrichtungen sind trotz ihrer Miniaturausführung immer noch relativ groß und haben ein nicht ganz zu vernachlässigendes Gewicht.A generic device is known from EP-A 04 26 980. In this application e.g. also describes a measuring device with a transmitter which emits light which is emitted by a light-sensitive receiver arrangement, e.g. is registered in the form of a diode array or a CCD camera. The output signal of these arrangements is then processed to adjust the angular position of the blade with respect to the circumference of the roller at the point of contact of the blade thereon. All measuring devices described in this application, despite their miniature design, are still relatively large and have a weight that is not to be neglected.

Die Aufgabe der Erfindung ist es, eine derartige Meßeinrichtung anzugeben, bei welcher ein Sensor mit merkbarem Gewicht vermieden ist. Eine andere Aufgabe ist es auch, die Meßeinrichtung so auszubilden, daß ein schnelles Wechseln der Klinge einschließlich der Meßwertübertragungseinrichtungen möglich ist.The object of the invention is to provide such a measuring device in which a sensor with a noticeable weight is avoided. Another object is also to design the measuring device in such a way that the blade, including the measured value transmission devices, can be changed quickly.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 bzw. 9 gelöst.This object is achieved according to the invention by the features of the characterizing part of patent claims 1 and 9, respectively.

Durch die lichtempfindliche auf der Klinge aufgebrachte Schicht, die das von einem Sender auf diese gestrahlte Licht nach dem bekannten Reflexionsgesetz reflektierte Licht zu einem Empfänger schickt, wird die Streichklinge nur örtlich durch zu vernachlässigende zusätzliche Gewichte belastet, und ein schnelles Wechseln derselben ist möglich. Bei der Verwendung eines Reflexionsstreifens kann dieser bereits vor Montage der Klinge auf dieser aufgebracht werden. Verwendet man ein Spiegelplättchen als reflektierende Schicht der Klinge können günstige Einfalls- und Ausfallswinkel der Meßstrahlen erreicht werden, indem der Träger der Spiegelfläche keilförmig ausgebildet ist. Der Träger kann ferner magnetisch sein, so daß ein schnelles Anheften an der Klinge und Entfernen von derselben möglich ist.Due to the light-sensitive layer on the blade, which sends the light reflected by a transmitter onto this light according to the known law of reflection to a receiver, the doctor blade is only locally loaded by negligible additional weights, and a quick change is possible. If a reflection strip is used, it can be applied to the blade before it is installed. If a mirror plate is used as the reflecting layer of the blade, favorable angles of incidence and reflection of the measuring beams can be achieved by the carrier of the mirror surface being wedge-shaped. The carrier may also be magnetic so that it can be quickly attached to and removed from the blade.

Es ist auch eine berührungsfreie Anordnung auf induktiver oder kapazitiver oder Ultraschall-Basis möglich, wobei der Sensor in einer bestimmten Entfernung von der Andruckleiste bzw. der Einspannung der Klinge angeordnet wird, so daß aufgrund der Ermittlung des Abstandes der Klinge vom Sensor in diesem Bereich und unter Berücksichtigung der Anpreßkraft der Klinge der Winkel der Klinge berechnet werden kann.A non-contact arrangement on an inductive or capacitive or ultrasound basis is also possible, the sensor being arranged at a certain distance from the pressure bar or the clamping of the blade, so that the distance between the blade and the sensor in this area and taking into account the contact pressure of the blade, the angle of the blade can be calculated.

Nachfolgend wird die Erfindung anhand der in den Figuren der Zeichnung dargestellten Ausführungsbeispiele erläutert, wobei im einzelnen darstellen:

  • Figur 1 eine prinzipmäßige Darstellung in Seitenansicht der erfindungsgemäßen Meßeinrichtung,
  • Figur 2 eine Einzelheit im Bereich der Anlagekante der Klinge an der Gegenwalze in vergrößertem Maßstab,
  • Figur 3 eine entsprechende Anordnung einer anderen Variante.
The invention is explained below on the basis of the exemplary embodiments illustrated in the figures of the drawing, in which:
  • FIG. 1 shows a schematic representation in a side view of the measuring device according to the invention,
  • FIG. 2 shows a detail in the area of the contact edge of the blade on the counter roller on an enlarged scale,
  • Figure 3 shows a corresponding arrangement of another variant.

In Figur 1 ist die Streichklinge 2 eingespannt in die Klemmbacken 3 und 4 eines Halters und wird an die Gegenwalze R mittels einer Druckleiste 5 angepreßt, die zwischen Führungsplatten 21 und 29 entsprechend dem Doppelpfeil verschieblich gehalten ist. Es ist ein Sender für Licht, insbesondere Laserlicht 9 vorgesehen, der einen Lichtstrahl 12 auf eine Lichtreflexionsschicht 8' schickt, von wo der reflektierte Strahl 13 zu dem Empfänger 10 in Form einer CCD-Anordnung mit einem Spreizungswinkel a gelangt. Die Reflexionsschicht 8' ist hier eine Spiegelschicht eines Spiegelplättchens 6, das mittels einer magnetischen Trägerplatte 7 an der Streichklinge lösbar befestigt ist (da ja die Streichklinge bekanntermaßen aus magnetisierbarem Stahl bestehen). Die Trägerplatte 7 ist keilförmig mit einem Winkel c ausgebildet, um einen günstigen Verlauf von Einfallsstrahl 12 und Reflexionsstrahl 13 zu erhalten. Dadurch gewinnt man genügend Raum, um in günstiger Weise den Sender 9 und den Empfänger 10 in der Nähe der Streichklinge anbringen zu können.In Figure 1, the doctor blade 2 is clamped in the jaws 3 and 4 of a holder and is pressed against the counter roller R by means of a pressure bar 5, which is held displaceably between guide plates 21 and 29 according to the double arrow. A transmitter for light, in particular laser light 9, is provided, which sends a light beam 12 onto a light reflection layer 8 ', from where the reflected beam 13 reaches the receiver 10 in the form of a CCD arrangement with a spread angle α. The reflection layer 8 'here is a mirror layer of a mirror plate 6, which is detachably attached to the doctor blade by means of a magnetic carrier plate 7 (since the doctor blade is known to consist of magnetizable steel). The carrier plate 7 is wedge-shaped with an angle c in order to obtain a favorable course of the incident beam 12 and the reflection beam 13. This gives you enough space to be able to attach the transmitter 9 and the receiver 10 in the vicinity of the doctor blade in a favorable manner.

In Figur 3 ist dargestellt, daß die Reflexionsschicht 8 auch auf einer Folie aufgebracht sein kann, die auf die Streichklinge 2 aufgeklebt werden kann oder - als Magnetfolie ausgebildet - einfach auf die Streichklinge aufgesetzt werden kann. Man kann hier einen Streifen von z.B. 5 cm Länge benutzen und diesen bereits vor Montage der Streichklinge auf dieser an der richtigen Stelle anbringen. Dadurch wird die Ausfallzeit der Streichanlage bei einem Wechsel der Streichklinge äußerst gering.In Figure 3 it is shown that the reflection layer 8 can also be applied to a film that can be glued to the doctor blade 2 or - designed as a magnetic film - can simply be placed on the doctor blade. You can use a strip of e.g. Use a length of 5 cm and attach it to the right place before installing the doctor blade. This minimizes the downtime of the coating system when changing the coating blade.

Das Signal von dem Empfänger 10 wird dann auf eine hier nicht dargestellte Regeleinrichtung gegeben, um den Winkel der Streichklinge einstellen zu können. Gemeint ist damit der Winkel b, mit dem die Streichklinge in Figur 1 und 2 an der Gegenwalze R anliegt. Entsprechend diesem Winkel verläuft ja auch die eigentliche Streichkante (Fase f) an dem Klingenende in Bezug auf die Gegenwalze R bzw. die von dieser geführten Papierbahn. Die Fase f soll natürlich genau tangential zur Gegenwalze und Papierbahn verlaufen. Dabei läuft die Papierbahn bzw. Walze R mit der Geschwindigkeit v entsprechend dem dargestellten Pfeil an der Streichklinge vorbei.The signal from the receiver 10 is then sent to a control device, not shown here, in order to be able to adjust the angle of the doctor blade. What is meant by this is the angle b with which the doctor blade lies against the counter roller R in FIGS. 1 and 2. According to this win The actual coating edge (chamfer f) at the blade end also runs in relation to the counter roller R or the paper web guided by it. Of course, the chamfer f should run exactly tangential to the counter roller and paper web. The paper web or roller R runs past the doctor blade at the speed v in accordance with the arrow shown.
