Abstract
Description
Die Erfindung betrifft eine Reifenaufbautrommel mit Lagenumschlag zur Herstellung von unvulkanisierten Reifenrohlingen.The The invention relates to a tire building drum with layer transfer to Production of unvulcanized green tires.
Bei der Herstellung von unvulkanisierten Reifenrohlingen werden typischerweise Luftbälge zur Bereitstellung der erforderlichen Andruckkräfte beim Lagenumschlag verwendet. Derartige Trommeln sind relativ teuer und machen in vorgegebenen zyklischen Abständen eine Auswechslung der Luftbälge erforderlich. Bekannt ist es aus der EP-A 1 001 876 auch bereits, mechanische Wulstumschlagvorrichtungen zur realisieren, bei denen der erforderliche Andruck unter Verwendung einer Vielzahl von einzelnen Hebeln erreicht wird, die ähnlich zu den Streben eines Regenschirmes angeordnet sind. Diese mechanischen Vorrichtungen weisen gegenüber einer Verwendung von Luftbälgen eine erhöhte Standzeit auf, ermöglichen jedoch keine symmetrischen Fahrbewegungen.at The production of unvulcanized green tires typically becomes air bags used to provide the necessary pressure forces during layer transfer. Such drums are relatively expensive and make in given cyclic intervals a replacement of the bellows required. It is already known from EP-A 1 001 876 already, mechanical Wulstumschlagvorrichtungen to realize in which the required pressure using a variety of individual Leverage is achieved, which is similar arranged to the struts of an umbrella. This mechanical Devices face a use of air bellows an increased Life on, allow but no symmetrical movements.
Aufgabe der vorliegenden Erfindung ist es, eine Reifenaufbautrommel der einleitend genannten Art derart zu konstruieren, daß die Durchführung von symmetrischen Verfahrbewegungen unterstützt wird.task The present invention is to provide a tire building drum of Initially mentioned type to construct such that the implementation of symmetrical Traversing movements supported becomes.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Lagenumschlag eine Mehrzahl von Rollenarmen aufweist, die mit einem Antrieb gekoppelt sind, der außerhalb der Reifenaufbautrommel angeordnet ist.These Task is inventively characterized solved, that the Layer envelope has a plurality of roller arms, which with a Drive are coupled to the outside the tire building drum is arranged.
Durch die Anordnung des Antriebes außerhalb der Reifenaufbautrommel ist es möglich, die Rollenarme über einen sogenannten Pusher zu betätigen, der absolut symmetrische Verfahrbewegungen vorgibt. Es können hierdurch Reifenrohlinge mit einer sehr hohen gleichmäßigen Qualität produziert werden.By the arrangement of the drive outside the tire building drum it is possible the roller arms over to push a so-called pusher, which specifies absolutely symmetrical movements. It can thereby Tire blanks produced with a very high uniform quality become.

Hierdurch wird eine flächige Anrollung beim Lagenumschlag erreicht und somit erfolgt eine Vermeidung von Lufteinschlüssen. Nach Vollendung des Lagenumschlages werden von externer Seite weitere Rohlingskomponenten zugeführt.hereby becomes a plane Rolling achieved when the sheet envelope and thus there is a prevention of air bubbles. Upon completion of the ply turn, additional blanks become external from the side fed.
Die Reifenaufbautrommel ist mit einer externen, bei Bedarf angekuppelten, servogesteuerten Kernsetzvorrichtung versehen. Hierdurch wird ein absoluter Synchronlauf der Rollensysteme beider Trommelhälften gewährleistet. Gleichzeitig gibt es durch den motorischen Synchronlauf keinerlei "stip-slic-Effekte" oder schwierige/instabile Einregelungen einer pneumatischen Rollenhebelbetätigung. Folglich ist für den Anwender eine deutlich verbesserte Rundlaufqualität/Uniformity zu erwarten. Insbesondere hinsichtlich besserer Konizität und Seitenkraftschwankungen.The Tire building drum is equipped with an external, if necessary coupled, servo-controlled Kernsetzvorrichtung provided. This will be an absolute Synchronous running of the roller systems of both drum halves guaranteed. At the same time there it does not have any "stip-slic-effects" or difficult / unstable due to the motor synchronous running Einregelungen a pneumatic roller lever actuation. Consequently, for the user to expect a significantly improved concentricity / uniformity. Especially for better taper and side force fluctuations.
