Description
Die Erfindung bezieht sich auf eine Heizvorrichtung für eine Wellpappenanlage, mit mehreren, in Förderrichtung einer Wellpappenbahn hintereinanderliegenden Heizplatten und darüber angeordneten, die Wellpappenbahn beaufschlagenden Druckelementen.The invention relates to a heating device for a corrugated cardboard plant, with several, one behind the other in the conveying direction of a corrugated cardboard web Heating plates and arranged above, which act on the corrugated cardboard web Pressure elements.
Eine derartige Vorrichtung an einer Wellpappenanlage hat die Aufgabe, Leim zwischen übereinander angeordneten Bahnen, d.h. beispielsweise einseitigen Wellpappenbahnen und zuletzt der Deckbahn, zu trocknen.Such a device on a corrugated cardboard system has the task of glue between tracks arranged one above the other, i.e. for example one-sided Corrugated cardboard sheets and finally the cover sheet to dry.
Zu diesem Zweck weisen bekannte Vorrichtungen Heizplatten auf, welche z.B. mit Dampf oder Thermoöl beheizt werden. Über einen durchgehenden Transportgurt wird die Bahn durch die Heizzone geführt. Druckelemente drücken die Wellpappenbahnen gegen die Oberflächen der Heizplatten, um einen entsprechenden Kontakt der Wellpappenbahnen mit der Heizplattenfläche, d.h. eine gute Wärmeübertragung zur Leimlinie, zu erreichen.For this purpose known devices have heating plates which e.g. be heated with steam or thermal oil. With a continuous conveyor belt the web is led through the heating zone. Pressure elements press the Corrugated cardboard sheets against the surfaces of the heating plates to a corresponding Contact of the corrugated cardboard webs with the hotplate surface, i.e. a good Heat transfer to the glue line.
Bei einer bekannten Druckeinheit werden außerdem Beschwerwalzen verwendet, welche über Zwischenhebel an einem quer zur Förderrichtung der Wellpappenbahn angeordneten Lager befestigt sind (US-PS 5,632,830).In a known printing unit, weighting rollers are also used, which via intermediate levers on a cross to the conveying direction of the corrugated cardboard web arranged bearings are attached (US Pat. No. 5,632,830).
Weiterer Stand der Technik ist ebenfalls eine Druckeinheit in Form einer Belastungsplatte, welche aus mehreren, sich längs der Wellpappenbahn erstreckenden Einheiten besteht (CA-PS 2,197,921). Darüber hinaus ist der Einsatz von Druckhauben bekannt (EP 0 412 255 A1), sowie Walzen, welche auf einen umlaufenden Fördergurt drücken (US-PS, 5,632,830). Another state of the art is also a printing unit in the form of a loading plate, which consist of several that extend along the corrugated cardboard web Units exist (CA-PS 2,197,921). In addition, the use of pressure hoods known (EP 0 412 255 A1), as well as rollers, which on a rotating Press the conveyor belt (US-PS, 5,632,830).
Um die Nachteile des Transportgurtes zu vermeiden, ist weiterer Stand der Technik (US-PS 5 632 830), dass auf den Gurt in der Heizzone verzichtet und die Wellpappenbahn über Andruckelemente direkt gegen die Heizflächen gedrückt wird.In order to avoid the disadvantages of the conveyor belt, further state of the art is (US Pat. No. 5,632,830) that dispenses with the belt in the heating zone and the corrugated cardboard web is pressed directly against the heating surfaces via pressure elements.
Wird nun auf diesen Transportgurt verzichtet, ist ein selbsttätiger Einzug der zugeführten Bahnen nicht mehr möglich; außerdem steigt die erforderliche Zugkraft infolge der erhöhten Reibarbeit stark an, was zu häufigen Abrissen in der Heizzone führt. Abrisse in Verbindung mit umständlicher Wiedereinführung bewirken nicht tragbare Produktionseinbußen.If this transport belt is now dispensed with, the automatic retraction is the fed webs no longer possible; the required tractive force also increases due to the increased friction work, resulting in frequent demolition in the Heating zone leads. Demolition in connection with cumbersome reintroduction cause unsustainable production losses.
Entsprechend liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Heizvorrichtung der eingangs genannten Art zu schaffen, welche in der Lage ist, die von vorhergehenden Anlageteilen zugeführten Bahnen einzuziehen und soweit zu verkleben, dass die Wellpappenbahn automatisch durch den gurtlosen Teil der Heizeinrichtung geführt wird.Accordingly, the present invention is based on the object To create a heater of the type mentioned, which is able to pull in the webs fed from previous system parts and so far to glue that the corrugated cardboard web automatically through the strapless Part of the heater is guided.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass im Anfangsbereich der Heizplatten zwischen zumindest einem Teil der Wellpappenbahn und mindestens einem Druckelement ein Einzugsband angeordnet ist. Mit Hilfe dieses Einzugsbandes besteht die Möglichkeit, die einzelnen Lagen der Wellpappenbahn funktionssicher miteinander zu verbinden und außerdem mögliche Reibungsverluste der vorhergehenden Anlagenteile auszugleichen.This object is achieved in that in the initial area of the heating plates between at least part of the corrugated cardboard web and at least a feed belt is arranged in a printing element. With the help of this feed belt there is the possibility of the individual layers of the corrugated cardboard web functionally connectable with each other and also possible friction losses to compensate for the previous parts of the system.
Das Einzugsband kann als ein über mindestens zwei im Abstand voneinander angeordnete Umlenkrollen laufendes Förderband ausgebildet sein. Hierbei besteht konstruktiv die Möglichkeit, dass das Förderband durch mindestens ein in Laufrichtung der Wellpappenbahn angeordnetes Druckelement beaufschlagbar ist. Weiterhin kann das Einzugsband beheizbar ausgebildet sein. The feed belt can be spaced from one another by at least two arranged deflection rollers running conveyor belt be formed. Here there is constructively the possibility that the conveyor belt by at least one in Direction of movement of the corrugated cardboard arranged pressure element can be acted upon is. Furthermore, the feed belt can be made heatable.
Zur guten Anpassung an die jeweiligen Gegebenheiten besteht die Möglichkeit, dass der Abstand der beiden Umlenkrollen veränderbar ist. Hierbei kann die hintere Umlenkrolle in Laufrichtung der Wellpappenbahn verschiebbar ausgebildet sein, wobei das Förderband über eine verstellbare Spannrolle läuft.For good adaptation to the respective circumstances, there is the possibility that the distance between the two pulleys can be changed. Here, the rear deflection roller designed to be slidable in the direction of travel of the corrugated cardboard web be, with the conveyor belt running over an adjustable tension roller.
Nach einer Ausführungsform der Erfindung besteht die Möglichkeit, dass durch die auf das Förderband einwirkenden Druckelemente alle Lagen der Wellpappenbahn beaufschlagbar sind. Alternativ ist es auch denkbar, beispielsweise bei drei Lagen der Wellpappenbahn durch die auf das Förderband einwirkenden Druckelemente zunächst nur zwei Lagen der Wellpappenbahn zu beaufschlagen und die dritte Lage hinter der zweiten Umlenkrolle der Wellpappenbahn zuzuführen. Diese dritte Lage kann beispielsweise über eine Zuführrolle der Wellpappenbahn transportiert werden.According to one embodiment of the invention, there is the possibility that the pressure elements acting on the conveyor belt all layers of the corrugated cardboard web are acted upon. Alternatively, it is also conceivable, for example with three layers of the corrugated cardboard web through those acting on the conveyor belt To apply pressure elements only two layers of the corrugated cardboard web and feed the third layer behind the second deflection roller to the corrugated cardboard web. This third layer can, for example, via a feed roller of the corrugated cardboard web be transported.
Um eine schnellere Verklebung zu erreichen, können vor der Zuführrolle beheizbare Andruckelemente vorgesehen sein.In order to achieve a faster gluing, heatable in front of the feed roller Pressure elements may be provided.
Eine besonders einfache Ausführungsform ergibt sich dann, wenn die Heizvorrichtung mit einer oberen und einer unteren Einzugswalze im Anfangsbereich der Heizplatten ausgebildet ist. In diesem Fall kann die obere Einzugswalze gleichzeitig die erste Umlenkrolle für das Förderband bilden.A particularly simple embodiment results when the heating device with an upper and a lower feed roller in the beginning of the Heating plates is formed. In this case, the upper feed roller can run simultaneously form the first deflection roller for the conveyor belt.
In weiterer Ausgestaltung der Erfindung kann auch die Zuführrolle beheizbar ausgebildet sein.In a further embodiment of the invention, the feed roller can also be heated be trained.
