Abstract
Description
Die Erfindung bezieht sich auf eine Separiervorrichtung zum Trennen einer Materialbahn, insbesondere einer Papier- oder Kartonbahn, in Bahnlaufrichtung in mehrere Teilbahnen, mit einem Mittel zum bogenförmigen Auftrennen der Teilbahnen.The invention relates to a separating device for separating a material web, in particular a paper or board web, in the web running direction into a plurality of sub-webs, with a means for arc-shaped separation of the sub-webs.
Eine aus einer Maschine zur Herstellung einer Faserstoffbahn aus einer Faserstoffsuspension erzeugte Materialbahn wird durch Schneideinrichtungen in Längsrichtung in mehrere nebeneinanderlaufende Teilbahnen geschnitten.A material web produced from a machine for producing a fibrous web from a pulp suspension is cut by cutting devices in the longitudinal direction into a plurality of side webs running in parallel.
Aus der
Aus der
Bevor die Teilbahnen in einer zwei Tragwalzen umfassenden und in einem von diesen gebildeten Walzenbett fluchtend nebeneinanderliegende Wickelrollen aufweisenden Wickelvorrichtung aufgewickelt werden können, müssen die Teilbahnen ausreichend separiert werden, um eine gegenseitige Störung beim Wickelvorgang zu vermeiden. Außerdem müssen sich die einzelnen Wickel nach Beendigung des Wickelvorgangs voneinander trennen lassen.Before the partial webs can be wound up in a winding device comprising two winding rolls and aligned in a roll bed arranged side by side in one of these roll beds, the part webs must be sufficiently separated in order to avoid mutual interference during the winding process. In addition, the individual coils must be separated from each other after completion of the winding process.
Als Mittel zur bogenförmigen Auftrennung der Teilbahnen dienen beispielsweise Walzen, die über ihre gesamte Breite konvex durchgebogen sind, so dass die Teilbahnen, die über eine derartige Walze geführt werden, im Bereich einiger Zehntel Millimeter voneinander getrennt werden. Dieselbe Wirkung lässt sich auch eine sogenannte Röllchenstreichleiste erreichen. Hierbei sind auf einer sich quer zur Bahnlaufrichtung erstreckenden Leiste viele Röllchen drehbar angeordnet, die durch motorische Antriebe in Richtung zu den Teilbahnen bewegbar sind und gegen diese derart drücken können, dass die Teilbahnen geringfügig auseinanderlaufen.As a means for arcuate separation of the partial webs serve, for example, rollers which are convexly bent over its entire width, so that the partial webs, which are guided over such a roller, are separated in the range of a few tenths of a millimeter from each other. The same effect can also be achieved by a so-called Röllchenstreichleiste. Here, many rolls are rotatably arranged on a transversely extending to the web running bar, which are movable by motor drives in the direction of the partial webs and can press against them so that the partial webs diverge slightly.

Es ist die Aufgabe der Erfindung, eine sichere Separierung der aus einer Materialbahn in einer Schneideinrichtung entstehenden Teilbahnen zu gewährleisten.It is the object of the invention to ensure a secure separation of the part webs resulting from a material web in a cutting device.
Erfindungsgemäß wird diese Aufgabe durch eine Vorrichtung gemäß des Anspruchs 1 gelöst.According to the invention, this object is achieved by a device according to claim 1.
Durch die Erfindung wird ein automatisierter Betrieb von Separiervorrichtungen ermöglicht. Im Unterschied zum Stand der Technik ist es gemäß der Erfindung nicht mehr erforderlich, dass ein Bediener manuell in den Bahntrennvorgang eingreift. Die Trennung der Schnitte der Materialbahn, insbesondere der Papierbahn, wird nun durch die Überwachungseinrichtung erfasst. Die für die Bahntrennung erforderlichen Komponenten lassen sich nun derart verstellen, bis die gewünschte Trennung der Schnitte erreicht ist. Selbst bei schwankender Qualität des Materials der Faserstoffbahn wird der Ausschuss durch eine vollautomatische Überwachung der Separiervorrichtungen verringert.The invention enables automated operation of separating devices. In contrast to the prior art, according to the invention, it is no longer necessary for an operator to intervene manually in the web separation process. The separation of the sections of the material web, in particular the Paper web, is now detected by the monitoring device. The components required for the web separation can now be adjusted until the desired separation of the cuts is achieved. Even with fluctuating quality of the material of the fibrous web, the rejects are reduced by a fully automatic monitoring of the separating devices.
Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen.Advantageous developments emerge from the subclaims, the description and the drawings.
Erfindungsgemäß sind mehrere Überwachungseinrichtungen nebeneinander angeordnet, wobei jede von ihnen zwei aneinander angrenzende Schnittkanten von Teilbahnen überwacht.According to the invention, a plurality of monitoring devices are arranged side by side, each of which monitors two adjoining cut edges of partial webs.
Vorzugsweise sind die Überwachungseinrichtungen in Bahnlaufrichtung und/oder quer zur Bahnlaufrichtung verfahrbar, insbesondere verschwenkbar, angeordnet, so dass sich sämtliche Teilbahnen überwachen lassen und die Überwachungseinrichtungen nach Bedarf an kritische Stellen im Verlauf der Teilbahnen geschwenkt werden können.Preferably, the monitoring devices are movable in the web running direction and / or transversely to the web running direction, in particular pivotable, arranged so that all sub-webs can be monitored and the monitoring devices can be swiveled as required to critical points in the course of the sub-webs.
Bei einer Separiervorrichtung ist es von Vorteil, wenn von der Überwachungseinrichtung erzeugte und bewertete Signale, insbesondere die, die Positionen der Schnittkanten der Teilbahnen entsprechen, einer Steuer- oder Regeleinrichtung zugeführt werden, so dass eine motorische Verstellung der als Stellglied dienenden Separiervorrichtung, d. h. der Röllchen in der Separiervorrichtung, automatisch erfolgt. Auf diese Weise lassen sich die Abstände der Teilbahnen aufgrund von Steuer- oder Regelsignalen einstellen. Anstelle oder zusätzlich zu einer Vielzahl von Röllchen kann auch eine Breitstreckwalze oder eine Kombination aus mehreren Breitstreckwalzen mit jeweils konvex gebogener Mantelfläche vorhanden sein, wobei sich die Bogenhöhe und/oder die Achslage der einen Breitstreckwalze oder der mehreren Breitstreckwalzen aufgrund von Signalen aus einer Steuer- oder Regeleinrichtung verstellen lässt bzw. lassen.In a separating device, it is advantageous if signals generated and evaluated by the monitoring device, in particular those corresponding to the positions of the cut edges of the partial webs, are fed to a control or regulating device, so that a motorized adjustment of the separating device serving as the actuator, ie the rolls in the separating device, takes place automatically. In this way, the Set the distances of the partial paths due to control or regulating signals. Instead of or in addition to a plurality of rolls may also be a spreader roll or a combination of several spreader rolls each having a convexly curved lateral surface, wherein the sheet height and / or the axial position of a spreader roll or the plurality of spreader rolls due to signals from a control or Control device can be adjusted or leave.
Mit Vorteil lassen sich somit die Überwachungseinrichtungen im Bereich einer Röllchenstreichleiste, einer Breitstreckwalze oder einer zwei schwenkbar auf einem Traggestell angeordnete Breitstreckwalzen umfassenden Anordnung einsetzen. Im Fall dieser Anordnung lassen sich vorzugsweise beide Breitstreckwalzen aufgrund von erfindungsgemäß gewonnenen optischen Signalen verstellen.Advantageously, the monitoring devices can thus be used in the area of a roller coating strip, a spreader roll or an arrangement comprising two spreader rolls arranged pivotably on a support frame. In the case of this arrangement, preferably both spreader rollers can be adjusted on the basis of optical signals obtained according to the invention.
In der Erfindung sind die Überwachungseinrichtungen Kameras, insbesondere CCD-Kameras. Die Überwachungseinrichtungen können aber auch mit elektromagnetischen Wellen im nicht-sichtbaren Bereich arbeiten.In the invention, the monitoring devices are cameras, in particular CCD cameras. The monitoring devices can also work with electromagnetic waves in the non-visible range.
Nachstehend wird die Erfindung in einem Ausführungsbeispiel anhand der einzigen Figur näher erläutert. Diese zeigt eine perspektivische Ansicht auf eine Separiervorrichtung mit einer Röllchenstreichleiste.The invention will be explained in more detail in an embodiment with reference to the single figure. This shows a perspective view of a separating device with a roller coating.
Eine in einer Maschine zur Herstellung einer Faserstoffbahn aus einer Faserstoffsuspension erzeugte Faserstoffbahn 1 (Figur) wird über eine Breitstreckwalze 2 geführt. Die Breitstreckwalze 2 hat eine bombierte Form, d. h. sie weist einen konvex gekrümmten Mantel 3 auf, der dazu dient, die Faserstoffbahn 1 quer zur Bahnlaufrichtung zu strecken.A fibrous web 1 (FIG. 1) produced in a machine for producing a fibrous web from a pulp suspension is guided over a
Anschließend wird die Faserstoffbahn 1 durch jeweils ein Untermesser und ein Obermesser umfassende Schneideinrichtungen 4, 5, 6 in zueinander parallele Teilbahnen 7, 8, 9, 10 geschnitten. Die Teilbahnen 7 bis 10 werden, bevor sie einer Wickelvorrichtung zugeführt werden, einer Einzelbahn-Separiervorrichtung 11 zugeführt, durch die sie jeweils einen Abstand zwischen 0 und 3 mm, vorzugsweise zwischen 0,5 und 1 mm, erhalten. Dadurch geraten die Wickelrollen, zu denen die Teilbahnen 7 bis 10 während des gemeinsamen Aufwickelns in der der Separiervorrichtung 11 in Bahnlaufrichtung nachfolgenden Wickelvorrichtung aufgewickelt werden, nicht miteinander in Berührung, und seitliche Beschädigungen der Wickel werden verhindert.Subsequently, the fibrous web 1 by a respective lower blade and a Upper knife
Die Separiervorrichtung 11 weist entweder eine zweite Breitstreckwalze auf, die dieselbe Form hat wie die Breitstreckwalze 2, oder es ist eine Röllchenstreichleiste 12 vorhanden, die eine Vielzahl von über die gesamte Bahnbreite aller Teilbahnen 7 bis 10 nebeneinander angeordneten Röllchen 13 umfasst. Diese sind jeweils einzeln durch motorische Verstelleinrichtungen 14 verstellbar, um partiell auftretende Bahnfehler in den Teilbahnen 7 bis 10, insbesondere an deren Rändern, durch Nachjustierung der Bogeneinstellung, die die Röllchen 13 miteinander bilden, auszugleichen.The
Zur Überwachung des Verlaufs der Teilbahnen 7 bis 10 sind als optische Überwachungseinrichtungen Kameras 15, 16, 17 oberhalb oder unterhalb des Verlaufs der Teilbahnen 7 bis 10 im Bereich der Separiervorrichtung 11 angeordnet. Die Kameras 15 bis 17 sind vorzugsweise auf einer (nicht dargestellten) Traverse angeordnet. Die Kameras 15 bis 17 sind zusätzlich in Bahnlaufrichtung verschwenkbar, so dass sie den Bereich der Schnittkanten zwischen den Teilbahnen 7 bis 10 über eine große Länge beobachten können. Zusätzlich oder alternativ sind sie quer zur Bahnlaufrichtung verschwenkbar.For monitoring the course of the
Alternativ lässt sich auch vorsehen, dass die Kameras 15 bis 17 auf Führungsschienen parallel zu den Schnittkanten der Teilbahnen 7 bis 10 verschoben werden können. In diesem Fall können die Kameras 15 bis 17 zusätzlich in Querrichtung verschwenkbar sein.Alternatively, it can also be provided that the
Alternativ ist vorgesehen, dass die Kameras 15 bis 17 auf jeweils eigenen Führungen, beispielsweise versetzt zueinander, quer zur Bahnlaufrichtung verschiebbar angeordnet sind. Die Kameras 15 bis 17 lassen sich jeweils einzeln verschieben und/oder verschwenken.Alternatively, it is provided that the cameras are arranged 15 to 17 on their own guides, for example, offset from one another, transversely to the web running direction. The
Die Kameras 15 bis 17 erzeugen aus den von den Teilbahnen 7 bis 10, insbesondere von den Bereichen ihrer Schnittkanten, aufgenommenen Bildern elektronische Signale, die einer Steuer- oder Regeleinrichtung als Führungsgrößen zugeführt werden, in der sie ausgewertet werden. Durch einen Vergleich mit Soll-Werten werden in der Steuer- bzw. der Regeleinrichtung Stell- bzw. Regelgrößen gewonnen, die den Röllchen 13 zugeführt werden, um deren Position entsprechend dem Verlauf der Teilbahnen 7 bis 10 anzupassen. Auf diese Weise gewährleistet die Erfindung eine andauernde und ununterbrochene Überwachung der Separiervorrichtung. Es versteht sich, dass sich die Kameras 15 bis 17 auch derart verfahren oder verschwenkt werden können, dass zusätzlich auch die Schneidmesser oder die Schneideinrichtungen 4 bis 6 in ihrer Funktion überwacht werden.The
