Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Reifenbauteilen aus Materialstreifen, welche auf einen Reifenrohling oder eine Aufbautrommel gewickelt werden, wobei eine Rundschnur aus einer Kautschukmischung, die in einem Extruder hergestellt wird, in einer Kalandriereinrichtung zum Materialstreifen verformt wird, wobei aus mindestens zwei stationär angeordneten Extrudern definierte Mengen an Kautschukmischungen an Zwischenspeicher abgegeben werden, welche wahlweise gegenüber der Kalandriereinrichtung positioniert werden und an diese die jeweilige Kautschukmischung zum Erstellen des Materialstreifens abgeben.The invention relates to a method for producing tire components from strips of material which are wound onto a green tire or a building drum, a round cord made of a rubber mixture produced in an extruder being deformed in a calendering device to form strips of material, at least two of which are stationary Extruders, defined amounts of rubber mixtures are delivered to intermediate storage, which are optionally positioned opposite the calendering device and deliver the respective rubber mixture to this for creating the material strip.
Bei bekannten Anlagen sind eine Belegeeinheit aus Zuführeinheit, Kalandriereinrichtung und Belegerolle sowie ein einziger Extruder vorgesehen, sodass ein Wechsel der Kautschukmischung für den Materialstreifen ein Entleeren und Neubefüllen des Extruders erfordert. Darüber hinaus ist es notwendig, die gesamte Extruder-Belegeeinheit zu bewegen, um den Materialstreifen gegenüber dem Rohling entsprechend zu positionieren.In known systems, a document unit consisting of a feed unit, calendering device and document roller and a single extruder are provided so that changing the rubber mixture for the material strip requires emptying and refilling the extruder. In addition, it is necessary to move the entire extruder document unit in order to position the material strip accordingly with respect to the blank.

Der Erfindung liegt die Aufgabe zu Grunde, auf unkomplizierte und rationelle Weise Materialstreifen aus unterschiedlichen Kautschukmischungen auf eine Reifenaufbautrommel oder einen Reifenrohling aufbringen zu können.The invention is based on the object of being able to apply strips of material made of different rubber mixtures to a tire building drum or a green tire in an uncomplicated and efficient manner.
Gelöst wird die gestellte Aufgabe erfindungsgemäß mit einem Verfahren, bei welchem jeder Zwischenspeicher zum Befüllen mit Kautschukmischung an einen Extruder angekoppelt wird und nach dem Befüllen abgekoppelt wird.The object set is achieved according to the invention with a method in which each intermediate store for filling with rubber mixture is coupled to an extruder and is uncoupled after filling.
Bei der Erfindung befüllen die stationären Extruder, unabhängig vom Fertigungsprozess, Zwischenspeicher mit Kautschukmischungen. Gemäß der Erfindung ist daher ein Wechsel der Kautschukmischung durch simples Wechseln des Zwischenspeichers und daher auf einfache und rationelle Weise möglich. Die Belegeeinheit kann sehr kompakt ausgeführt werden, da die Zwischenspeicher wesentlich weniger Platz beanspruchen als eine komplexe Extruder-Belegeeinheit.In the case of the invention, the stationary extruders fill intermediate stores with rubber compounds, regardless of the manufacturing process. According to the invention, it is therefore possible to change the rubber mixture by simply changing the intermediate store and therefore in a simple and efficient manner. The document unit can be made very compact, since the intermediate storage takes up much less space than a complex extruder document unit.
Beim erfindungsgemäßen Verfahren werden die Zwischenspeicher zum Befüllen mit Kautschukmischung an Extruder angekoppelt und nach dem Befüllen abgekoppelt. Die Zwischenspeicher können auch zwischengelagert werden, wobei es von Vorteil ist, wenn die Zwischenspeicher beheizt werden können, um eine gute Verarbeitbarkeit der in ihnen enthaltenen Kautschukmischungen sicherzustellen.In the method according to the invention, the intermediate stores for filling with rubber mixture are coupled to the extruder and are uncoupled after filling. The intermediate stores can also be temporarily stored, it being advantageous if the intermediate stores can be heated in order to ensure good processability of the rubber mixtures they contain.
Des weiteren kann vorteilhafterweise vorgesehen sein, dass die Kautschukmischungsmasse aus dem Zwischenspeicher auf gesteuerte Weise abgeben wird. Es kann daher kontrolliert Kautschukmischung dem jeweiligen Speicher entnommen werden, sodass das Aufbringen des Materialstreifens auf den Reifenrohling oder die Reifenaufbautrommel in der dem jeweiligen Bauteil angepassten Weise erfolgen kann.Furthermore, it can advantageously be provided that the rubber compound is released from the intermediate store in a controlled manner. The rubber mixture can therefore be removed from the respective storage unit in a controlled manner, so that the material strip can be applied to the green tire or the tire building drum in a manner adapted to the respective component.

Um eine optimale Verarbeitbarkeit der Kautschukmischungsmasse auch bei einer etwaigen Zwischenlagerung der gefüllten Speicher
Die Erfindung ermöglicht es, unterschiedliche Reifenbauteile, auch für unterschiedliche Reifentypen, aus Materialstreifen unterschiedlicher Kautschukmischungen aufzubauen. Es ist ein schneller Wechsel zwischen den Zwischenspeichern
Die Erfindung ist auf die dargestellten und beschriebenen Ausführungsvarianten nicht eingeschränkt. Die Reifenaufbautrommel kann zylindrisch oder in beliebiger Weise konturiert ausgeführt sein. Das Aufbringen des Materialstreifens kann sowohl auf dem Reifenrohling, wie dargestellt, oder, je nach Reifenbauteil, auch direkt auf einer Aufbautrommel erfolgen. Die Erfindung kann bei unterschiedlichen Reifenaufbauverfahren eingesetzt werden. Des Weiteren ist es möglich, das Wickeln bzw. Spulen des Materialstreifens auch auf einem bombierten Reifenrohling durchzuführen.The invention is not restricted to the embodiment variants shown and described. The tire building drum can be designed to be cylindrical or contoured in any way. The application of the strip of material can take place either on the green tire, as shown, or, depending on the tire component, also directly on a building drum. The invention can be used in various tire building processes. It is also possible to wind or reel the strip of material on a cambered green tire.
