Die Erfindung betrifft eine Heizvorrichtung für eine Wellpappenanlage mit den Merkmalen des Oberbegriffs des Patentanspruches 1.The invention relates to a heating device for a corrugated cardboard system with the features of the preamble of claim 1.

Es sind Heizvorrichtungen für eine Wellpappenanlage bekannt. Diese sogenannten Heizpartien besitzen mehrere, in Laufrichtung der Wellpappenbahn angeordnete Heizplatten, die meist mittels Heißdampf beheizt werden. Diese Heizplatten bilden mit ihrer Oberseite eine ebene, glatte Heizfläche. Über diese Heizfläche läuft die Wellpappenbahn. Sie wird über einen angetriebenen Endlosgurt und Andrückvorrichtungen in Form von mechanischen Andrückwalzen oder pneumatischen Druckhauben an die Heizfläche angedrückt. Die Andrückvorrichtungen und/oder die Temperatur der Heizfläche ist abhängig von Faktoren, wie z. B. Laufgeschwindigkeit der wellpappenbahn, Feuchtigkeitswerte und dgl., steuerbar. Nachteilig ist, daß bei den bisherigen Heizvorrichtungen getrennte oder integrierte Zugpartien mit zusätzlichen Bauteilen vorgesehen sind.Heating devices for a corrugated cardboard plant are known. These so-called heating sections have several heating plates arranged in the direction of travel of the corrugated cardboard web, which are usually heated by superheated steam. With their top, these heating plates form a flat, smooth heating surface. The corrugated cardboard web runs over this heating surface. It is pressed onto the heating surface via a driven endless belt and pressure devices in the form of mechanical pressure rollers or pneumatic pressure hoods. The pressing devices and / or the temperature of the heating surface depends on factors such as. B. running speed of the corrugated cardboard web, moisture values and the like, controllable. It is disadvantageous that separate or integrated train parts with additional components are provided in the previous heating devices.

Der Erfindung liegt die Aufgabe zugrunde, eine Heizvorrichtung zu schaffen, die ohne zusätzliche, eine Zugpartie bildende Bauteile die gewünschte Förderung der Wellpappenbahn erreicht.The invention has for its object to provide a heating device which achieves the desired conveyance of the corrugated cardboard web without additional components forming a train section.

Die Erfindung löst diese Aufgabe mit den die Erfindung kennzeichnenden Merkmalen nach Patentanspruch 1.The invention solves this problem with the features characterizing the invention according to patent claim 1.

Diese Heizvorrichtung ist zugleich Fördervorrichtung für die Wellpappenbahn, ohne daß zusätzliche Förderbauteile notwendig sind. Entscheidend ist, daß als Fördervorrichtung für die Wellpappenbahn nur der Endlosgurt verwendet ist.This heating device is at the same time a conveyor device for the corrugated cardboard web, without additional conveyor components being necessary. It is crucial that only the endless belt is used as the conveyor for the corrugated cardboard web.

Die Andrückvorrichtung wird wie üblich von Beschwerwalzen oder wenigstens einer Druckhaube gebildet.As usual, the pressing device is formed by weighting rollers or at least one pressure hood.

Vor und/oder nach der Heizfläche sind vorzugsweise Fühler vorzusehen, die die Temperatur bzw. Feuchtigkeit der zulaufenden einseitigen Wellpappenbahn, Deckbahn bzw. auslaufenden Wellpappenbahn messen, wobei die Anpreßwerte der Andrückvorrichtung abhängig von den Temperatur- bzw. Feuchtigkeitsmeßwerten gesteuert sind.Before and / or after the heating surface, sensors are preferably to be provided which measure the temperature or moisture of the incoming single-sided corrugated cardboard web, top web or outgoing corrugated cardboard web, the pressure values of the pressing device being controlled as a function of the temperature or moisture measurement values.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.

Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.

Die Zeichnung zeigt eine schematische Seitenansicht einer Heizvorrichtung für eine Wellpappenanlage.The drawing shows a schematic side view of a heating device for a corrugated cardboard system.

Die Heizvorrichtung 1 weist wie üblich einen Ständer 2 auf, der liegend hintereinander angeordnete Heizplatten 3 trägt. Die Heizplatten 3 bilden mit ihrer Oberseite eine ebene, glatte Heizfläche 4.As usual, the heating device 1 has a stand 2 which carries heating plates 3 arranged one behind the other in a lying manner. The upper side of the heating plates 3 forms a flat, smooth heating surface 4.

Quer zur Laufrichtung der Wellpappenbahn 5 können die Heizplatten 3 unterteilt sein.The heating plates 3 can be divided transversely to the direction of travel of the corrugated cardboard web 5.

Die Heizplatten 3 sind durch beliebige Heizmittel, z. B. Dampf, elektrische Heizmittel oder dgl. erhitzt. Die Temperatur der Heiz-fläche 4 kann einen vorbestimmten Temperaturwert aufweisen. Der Temperaturwert kann in Längs- oder Querrichtung der Laufrichtung der Wellpappenbahn 5 vorgegeben sein. Es ist auch möglich, diese Temperaturwerte abhängig von der Geschwindigkeit der Bewegung der Wellpappenbahn 5 zu steuern. Die Steuerung der Heizplattentemperatur kann auch über Meßfühler, abhängig von der Feuchtigkeit der Wellpappenbahn 5 bzw. der Leimauftragsmenge auf die Wellpappenbahn 5 erfolgen.The heating plates 3 are by any heating means, for. B. steam, electric heating means or the like. Heated. The temperature of the heating surface 4 can have a predetermined temperature value. The temperature value can be predetermined in the longitudinal or transverse direction of the running direction of the corrugated cardboard web 5. It is also possible to control these temperature values depending on the speed of the movement of the corrugated cardboard web 5. The control of the heating plate temperature can also be done via sensors, depending on the Moisture of the corrugated cardboard web 5 or the amount of glue applied to the corrugated cardboard web 5.

Neben oder statt der Steuerung der Temperatur der Heizfläche 4 kann auch der Andruck der Wellpappenbahn 5 an die Heizfläche 4 vorbestimmt sein oder gesteuert werden.In addition to or instead of controlling the temperature of the heating surface 4, the pressure of the corrugated cardboard web 5 against the heating surface 4 can also be predetermined or controlled.

Die über die Heizfläche 4 sich bewegende und an dieser anliegende Wellpappenbahn 5 läuft am Einlaufende 6 der Heizfläche 4 zu und am Auslaufende 7 aus. Sie bewegt sich in der angegebenen Pfeilrichtung I.The corrugated cardboard web 5 which moves over the heating surface 4 and lies against it runs towards the heating surface 4 at the inlet end 6 and ends at the outlet end 7. It moves in the direction indicated by arrow I.

An der Oberseite der Wellpappenbahn 5 anliegend läuft ein Endlosgurt 10, der in der angegebenen Pfeilrichtung II umläuft und die Wellpappenbahn 5 in der angegebenen Förderrichtung bewegt. Dieser Endlosgurt 10 wird durch einen Antriebsmotor 11 über eine Antriebswalze 12 angetrieben. Der Endlosgurt 10 läuft über eine Um-lenkwalze 13, Leitwalzen 14 und Spannwalzen 15.Adjacent to the top of the corrugated cardboard web 5, an endless belt 10 runs, which rotates in the arrow direction II indicated and moves the corrugated cardboard web 5 in the specified conveying direction. This endless belt 10 is driven by a drive motor 11 via a drive roller 12. The endless belt 10 runs over a deflection roller 13, guide rollers 14 and tensioning rollers 15.

Überhalb dem unterem Trum 16 des Endlosgurtes 10 befinden sich eine oder mehrere Andrückvorrichtungen 17, die das untere Trum 16 des Endlosgurtes 10 gegen die Oberseite der Wellpappenbahn 5 drücken. Diese Andrückvorrichtungen 17 können mechanischer Art, z. B. wie bekannt, durch heb- und senkbare Andrückwalzen oder aber pneumatisch durch Druckhauben gebildet sein. Die Andrückvorrichtungen 17 bestimmen die übertragene Wärmeenergie auf die Wellpappenbahn 5. Durch die Andrückvorrichtungen 17 wird ggf. zusätzlich auch der Wert der Haftreibung zwischen Endlosgurt und Wellpappenbahn bestimmt. Die Heizvorrichtung 1 ist zugleich auch die Fördervorrichtung für die Wellpappenbahn 5. Somit muß der Andrückwert des Endlosgurtes 10 an die Oberseite der Wellpappenbahn 5 so bemessen sein, daß die Haftreibung des Endlosgurtes 10 gegenüber der Wellpappenbahn 5 stets größer ist als die Gleitreibung zwischen Wellpappenbahn 5 und Heizfläche 4.Above the lower run 16 of the endless belt 10 there are one or more pressing devices 17 which press the lower run 16 of the endless belt 10 against the top of the corrugated cardboard web 5. These pressing devices 17 can be of a mechanical type, e.g. B. as known, be formed by lifting and lowering pressure rollers or pneumatically by pressure hoods. The pressing devices 17 determine the thermal energy transferred to the corrugated cardboard web 5. The pressing devices 17 may also determine the value of the static friction between the endless belt and the corrugated cardboard web. The heating device 1 is also the conveyor for the corrugated cardboard web 5. Thus, the pressure value of the endless belt 10 on the top of the corrugated cardboard web 5 must be such that the static friction of the endless belt 10 relative to the corrugated cardboard web 5 is always greater than the sliding friction between the corrugated cardboard web 5 and Heating surface 4.

Der zulaufenden einseitigen Wellpappe 20 und/oder der Deckbahn 21 und/oder der auslaufenden Pappe 22 sind Meßfühler 23, 24 oder 25 zugeordnet. Über eine nicht dargestellte Steuereinrichtung werden die Andrückvorrichtungen 17 abhängig von den über die Meßfühler gemessenen Temperatur- bzw. Feuchtigkeitswerten hinsichtlich des Anpreßwertes gesteuert. Überschreiten die gemessenen Werte einen vorbestimmten Wert, werden die Andrückwerte der Andrückvorrichtungen 17 erniedrigt und umgekehrt.The incoming one-sided corrugated cardboard 20 and / or the cover sheet 21 and / or the outgoing cardboard 22 are associated with sensors 23, 24 or 25. The pressing devices 17 are controlled via a control device (not shown) depending on the temperature or humidity values measured via the measuring sensors with regard to the contact value. If the measured values exceed a predetermined value, the pressure values of the pressure devices 17 are reduced and vice versa.

Zusätzlich kann auch die Temperatur bzw. Feuchtigkeit der zulaufenden Bahnen beeinflußt werden, indem ein bekannter Vorheizer mit Heiztrommel verwendet ist, dessen Temperatur bzw. Bahnumschlingungswinkel gesteuert wird.In addition, the temperature or humidity of the incoming webs can also be influenced by using a known preheater with a heating drum, the temperature or web wrap angle of which is controlled.
