Description

DEUTSCHESGERMAN

Die Erfindung betrifft eine Einrichtung an Vulkanisiermaschinen mit einer rotierenden Trommel und einem Anpreßband für das zu vulkanisierende Gut, wobei sowohl die Trommel als auch das Anpreßband beheizt sind und die Beheizung des Anpreßbandes mittels Strahlungswärme erfolgt.The invention relates to a device on vulcanizing machines with a rotating drum and a pressure belt for the material to be vulcanized, wherein both the drum and the pressure belt are heated and the heating of the pressure belt takes place by means of radiant heat.

Nach dem Hauptpatent 1 030' 012 werden derartige Vulkanisiermaschinen dadurch verbessert, daß die Beheizung des Anpreßbandes unter Zuhilfenahme von Infrarotstrahlern erfolgt, wobei die Strahler so angeordnet sind, daß die Einlaufstelle für das zu vulkanisierende Gut stärker beheizt wird als die Auslaufstellen und an der Einlaufstelle zwischen dem zu vulkanisierenden Gut und der Trommel Strahlungsquellen vorgesehen sind. Durch diesen Vorschlag ist die Möglichkeit gegeben, das Anpreßband im Vergleich zu der bekannten, mittels Dampf bewirkten Rückenheizung des Anpreßbandes intensiver, insbesondere so stark zu erwärmen, daß seine Temperatur der des Walzen mantels entspricht. aoAccording to the main patent 1 030 '012 such vulcanizing machines are improved in that the heating of the pressure belt is carried out with the aid of infrared radiators, the radiators being arranged in this way are that the inlet point for the material to be vulcanized is heated more strongly than the outlet points and radiation sources at the point of entry between the material to be vulcanized and the drum are provided. This proposal gives the possibility of the pressure band compared to the known, by means of steam back heating of the pressure belt more intense, in particular so strong heat that its temperature corresponds to that of the roll jacket. ao

Es wurde gefunden, daß die Leistung derart beheizter Vulkanisiermaschinen um mehr als das Doppelte gesteigert werden kann, wenn gleichzeitig die Rückenfläche des Anpreßbandes beaufschlagende, im Bereich der plastischen Verformung des Vulkanisates angeordnete Anpreßrollen verwendet werden.It has been found that the performance of vulcanizing machines heated in this way is more than that Can be doubled if at the same time the back surface of the pressure band acting on, im Pressure rollers arranged in the area of the plastic deformation of the vulcanizate are used.

An sich ist es bei dampfbeheizten Vulkanisiermaschinen bekannt, Anpreßrollen im Bereich der plastischen Verformung des Vulkanisates zu verwenden. Die Verwendung von Anpreßrollen erfolgt hierbei aber ausschließlich zur Entlastung des nicht beheizten Anpreßbandes, so daß dieses mit geringerer Spannung um die Vulkanisiertrommel gelegt werden kann. Die hierdurch erzielte technische Wirkung steht somit nicht im Zusammenhang mit dem Vulkanisationsvorgang und der Leistung der Maschine, d. h. mit der Umlaufgeschwindigkeit der beheizten Trommel.It is known per se in steam-heated vulcanizing machines, pressure rollers in the area of the to use plastic deformation of the vulcanizate. The use of pressure rollers takes place but here only to relieve the unheated pressure belt, so that this with less Tension can be placed around the vulcanizing drum. The technical effect achieved in this way is in place thus not related to the vulcanization process and the performance of the machine, d. H. with the speed of rotation of the heated drum.

Indessen besteht nach dem erfindungsgemäßen Vorschlag eine innere Beziehung zwischen der erst durch die Strahlungswärme möglichen erhöhten Temperatur des Anpreßbandes und seinem Anpreßdruck gegen das um die Trommel geführte Vulkanisat. Wie sich gezeigt hat, läßt sich bei mit strahlungsbeheizten Anpreßbändern ausgerüsteten Vulkanisiermaschinen die Strahlungswärme nicht im gewünschten Umfange zur Anwendung bringen und ausnutzen, da infolge der Intensität der Beheizung eine Übervulkanisation eintritt. Dies läßt sich nicht durch erhöhte Arbeitsgeschwindigkeit unterbinden. Eine solche ist aber überraschenderweise unter Vermeidung einer Übervulkanisation möglich, wenn das Vulkanisat im Bereich seiner plastischen Verformung eine zusätzliche Anpressung erfährt.However, according to the proposal according to the invention, there is an internal relationship between the first through the radiant heat possible increased temperature of the pressure belt and its contact pressure against the vulcanizate guided around the drum. As has been shown, can with radiation-heated pressure belts equipped vulcanizing machines do not use the radiant heat to the desired extent Apply and take advantage of the fact that over-vulcanization occurs due to the intensity of the heating. This cannot be prevented by increasing the working speed. Surprisingly, however, such is the case possible while avoiding over-vulcanization if the vulcanizate is in the area of its plastic deformation experiences an additional pressure.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Die Zeichnung zeigt eine Seitenansicht einer schematisch dargestellten Vulkanisiermaschine.The drawing shows a side view of a schematically illustrated vulcanizing machine.

Die Vulkanisiermaschine besteht im wesentlichen aus einer beheizten Trommel 1, die in Richtung des Pfeiles 2 rotiert. Das als Stahlband ausgebildete Anpreßband 3 ist um die Trommel 1 herumgeführt, und es bewegt sich ebenfalls in Richtung des Pfeiles 2. Das bereits bandförmig angelieferte, zu vulkanisierende Gut 4 wird auf das Stahlband 3 gelegt, so daß dieses zwischen Anpreßband 3 und der Trommel 1 gelangt. Das fertige Vulkanisat 4' verläßt die Trommel 1 an der Stelle 5.The vulcanizing machine consists essentially of a heated drum 1, which in the direction of the Arrow 2 rotates. The pressure band 3, designed as a steel band, is guided around the drum 1, and it also moves in the direction of arrow 2. The one that has already been delivered in the form of a tape and is to be vulcanized Good 4 is placed on the steel belt 3 so that it passes between the pressure belt 3 and the drum 1. The finished vulcanizate 4 ′ leaves the drum 1 at point 5.

Die Beheizung des Anpreßbandes 3 erfolgt mit Hilfe von Infrarotstrahlern 6. Die Rückenfläche des Anpreßbandes 3 wird im Bereich der plastischen Verformung des Vulkanisates 4 durch eine Andrückrolle 9 beaufschlagt. Es sei erwähnt, daß gegebenenfalls mehrere in Umfangsrichtung der Trommel gegeneinander versetzte Andrückrollen zur Anwendung kommen können.The pressure belt 3 is heated with the aid of infrared emitters 6. The back surface of the pressure belt 3 is in the area of plastic deformation of the vulcanizate 4 is acted upon by a pressure roller 9. It should be mentioned that several Pressure rollers offset from one another in the circumferential direction of the drum can be used.
