Description

Vorrichtung zum Aufbringen ringförmiger zylindrischer Reifenaufbauteile auf die Trommel einer Reifenaufbaumaschine Die Erfindung betrifft eine Vorrichtung zum Aufbringen ringförmiger zylindrischer Reifenaufbauteile auf die Trommel einer Reifenaufbaumaschine mit einem axial über die Trommel bewegbaren, im Bereich der Ränder mit Dichtungen versehenen Hohlzylinder zur Aufnahme der durch Vakuum auf der Innenseite des Hohlzylinders haltbaren Aufbauteile.Apparatus for applying annular cylindrical tire building components on the drum of a tire building machine The invention relates to a device for applying annular cylindrical tire building components to the drum of a Tire building machine with an axially movable over the drum, in the area of Hollow cylinders provided with seals to accommodate the vacuum on the edges the inside of the hollow cylinder durable structural parts.

Bei bekannten Vorrichtungen dieser Art ist der Hohlzylinder im Durchmesser nicht veränderbar; an den Rändern dieses Zylinders befinden sich aus festem Werkstoff bestehende Leisten, gegen die sich die zylindrischen Reifenaufbauteile anlegen können. In known devices of this type, the hollow cylinder is in diameter unchangeable; on the edges of this cylinder are made of solid material existing strips against which the cylindrical tire construction parts can rest.

Somit können sich die Randleisten nicht elastisch verformen, und sie sind nur dann in der Lage, eine ausreichende Abdichtung herbeizuführen, wenn die Reifenaufbauteile satt an den Randleisten anliegen.Thus, the edge strips can not deform elastically, and they are only able to create an adequate seal if the Tire construction parts lie snugly against the edge strips.

Es sind zwar Vorrichtungen zur Behandlung von Reifenrohlingen bekannt, bei denen elastisch verformbare, mit dem Reifenrohling in Berührung kommende Randleisten mit gerundetem Kopfteil vorgesehen sind. Bei diesen Vorrichtungen handelt es sich jedoch um Vakuumbombiervorrichtungen, bei denen die verformbaren Randleisten die glatte Außenfläche des Reifenrohlings berühren. Although there are known devices for treating green tires, in the case of elastically deformable edge strips that come into contact with the green tire are provided with a rounded head part. These devices are however, to vacuum crowning devices in which the deformable edge strips the touch the smooth outer surface of the green tire.

Im Gegensatz hierzu soll eine Vorrichtung der eingangs erwähnten Art so ausgebildet werden, daß sie für Reifenaufbauteile mit unterschiedlichem Durchmesser verwendbar ist, wobei gleichzeitig die Forderung erfüllt wird, daß eine wirksame Vakuumabdichtung möglich ist. In contrast to this, a device of the type mentioned at the outset is intended Kind are designed so that they are suitable for tire components with different diameters is usable, while at the same time the requirement is met that an effective Vacuum sealing is possible.

Erfindungsgemäß besteht bei der obengenannten Vorrichtung der Hohlzylinder aus über seinen Umfang verteilt angeordneten radial verstellbaren Segmenten, die entlang der Segmentränder als Lippendichtungen ausgebildete Dichtungen aufweisen. According to the invention, there is the hollow cylinder in the above-mentioned device from radially adjustable segments distributed over its circumference, which have seals formed as lip seals along the segment edges.

Während die erwähnten Segmente unterschiedliche wirksame Durchmesser des Hohlzylinders und damit eine Einstellung auf unterschiedliche Reifenaufbauteile zulassen, können sich die als Lippendichtungen ausgebildeten Dichtungen weitgehend der Außenfläche der Reifenaufbauteile anpassen, um so die Wirksamkeit der Abdichtung bei der Vakuumanwendung sicherzustellen. Die Lippendichtungen können sich auf Unebenheiten der Reifenaufbauteile aber auch bei steifen Reifenaufbauteilen auf unterschiedliche Krümmungsradien der Segmente einerseits und. der Reifenaufbauteile andererseits einstellen. While the mentioned segments have different effective diameters of the hollow cylinder and thus an adjustment to different tire components allow, the seals designed as lip seals can largely adapt to the outer surface of the tire construction parts, so as to increase the effectiveness of the seal ensure when applying vacuum. The lip seals can affect bumps of the tire components but also with stiff tire components to different Radii of curvature of the segments on the one hand and. the tire building parts on the other hand to adjust.

Weitere Einzelheiten der Vorrichtung werden an Hand der Zeichnung erläutert, in der Ausführungsteile dargestellt sind. Es zeigt Fig. 1 eine Vorrichtung zum Aufbringen von ringförmigen Reifenaufbauteilen, auf eine Reifenaufbautrommel in der Ansicht, teilweise im Schnitt, Fig. 2 die Vorrichtung gemäß Fig. 1 in der Seitenansicht und F i g. 3 eine Einzelheit aus F i g. 2. Further details of the device are based on the drawing explained, in the execution parts are shown. 1 shows a device for applying annular tire building components on a tire building drum in a view, partially in section, FIG. 2 shows the device according to FIG. 1 in FIG Side view and FIG. 3 shows a detail from FIG. 2.

Die Reifenaufbaumaschine 1 weist eine an dem freien Ende einer Welle 2 gelagerte Trommel 3 zum Aufbau eines Reifenrohlings auf. Koaxial und im Abstand von der Trommel 3 ist eine Blähtrommel 4 mit einem Druckluftanschluß 6 vorgesehen. Zur Aufnahme der ringförmigen Reifenaufbauteile ist der Blähtrommel 4 ein Hohlzylinder 7' zugeordnet. The tire building machine 1 has a shaft at the free end 2 mounted drum 3 for building a green tire. Coaxial and at a distance A blowing drum 4 with a compressed air connection 6 is provided from the drum 3. The inflatable drum 4 is a hollow cylinder to accommodate the ring-shaped tire construction parts 7 'assigned.

Der Hohlzylinder 7' besteht aus über den Trommelumfang verteilten, mittels Spindeln 16 verstellbaren Segmenten 17. Die einzelnen Segmente 17, die mit einer luftdurchlässigen Auskleidung 12 versehen sein können, weisen Vakuumanschlüsse 11' auf. Zudem befinden sich an ihren Rändern Dichtungen 14 mit Lippen 15, die nicht ringförmig ausgebildet sind, sondern dem Verlauf der Ränder der Segmente 17 angepaßt sind. The hollow cylinder 7 'consists of distributed over the drum circumference, by means of spindles 16 adjustable segments 17. The individual segments 17, which with an air-permeable lining 12 can be provided, have vacuum connections 11 'on. In addition, there are seals 14 with lips 15 on their edges, which are not are ring-shaped, but adapted to the course of the edges of the segments 17 are.

Der Hohlzylinder 7' ist an Führungen 18 des Trommelbockes 19 der Trommel 4 verschiebbar gelagert und mittels Arbeitszylinder 20 bewegbar, und zwar so, daß der Hohlzylinder 7' über die Trommel 3 geführt werden kann. The hollow cylinder 7 'is on guides 18 of the drum bracket 19 of the Drum 4 slidably mounted and movable by means of working cylinder 20, namely so that the hollow cylinder 7 'can be guided over the drum 3.

Durch eine Verstellung der Segmente 17 bzw. eine Betätigung der Spindeln 16 kann der wirksame Durchmesser des Hohlzylinders 7' zum Zwecke der Anpassung an Trommeln 3 unterschiedlicher Größe verändert werden. Das Auflegen der nur angedeuteten Karkaßlage 10 erfolgt mit Hilfe der Blähtrommel 4. By adjusting the segments 17 or actuating the spindles 16 can be the effective diameter of the hollow cylinder 7 'for the purpose of adaptation Drums 3 different sizes can be changed. The hanging up of the only hinted at The carcass ply 10 takes place with the aid of the inflatable drum 4.

Die zu einem ringförmigen Band zusammengeschlossene Karkasslage 10 aus einander parallelen in Kautschuk gebetteten Cordfäden wird zunächst über die Blähtrommel 4 geschoben. Ferner wird der Hohlzylinder7' so verfahren, daß er die Blähtrommel 4 umschließt. Durch Einleiten eines Druckmittels über den Anschluß 6 wird der Durchmesser der Trommel 4 vergrößert, wobei die Karkaßlage 10 gedehnt wird. The carcass ply 10 joined to form an annular band made of parallel cords embedded in rubber is first used over the Inflation drum 4 pushed. Furthermore, the hollow cylinder 7 'is moved so that he the Inflating drum 4 encloses. By introducing a pressure medium via connection 6 the diameter of the drum 4 is increased, whereby the carcass ply 10 is stretched.

Ist die Karkasslage 10 so weit gedehnt, das ihr Außendurchmesser in etwa dem wirksamen Innendurchmesser des Hohlzylinders 7' entspricht, so werden die Vakuumanschlüsse 11' eingeschaltet, so daß die Karkaßlage 10 in gedehntem Zustand an der Innenfläche des Hohlzylinders 7' anliegt und auch in dieser Stellung verharrt. Nachdem so der Hohlzylinder 7' die Karkasslage 10 aufgenommen hat, wird der Hohlzylinder7' über die Trommel3 verfahren. Durch Belüften der Leitungen 11 der Vakuumanschlüsse 11' wird die Haltekraft unwirksam und durch die in der Karkaßlage 10 vorhandene Eigenspannung verringert sich der Durchmesser der Karkaßlage 10, so daß sie sich nunmehr an die Außenfläche der Trommel 3 anlegt. If the carcass ply 10 is stretched so far that its outer diameter corresponds approximately to the effective inner diameter of the hollow cylinder 7 ', so are the vacuum connections 11 'switched on, so that the carcass ply 10 is in the stretched state rests against the inner surface of the hollow cylinder 7 'and also remains in this position. After the hollow cylinder 7 'has received the carcass ply 10, the hollow cylinder 7' is Move over the drum3. By venting the lines 11 of the vacuum connections 11 ', the holding force becomes ineffective and is caused by that which is present in the carcass ply 10 Residual stress reduces the diameter of the Carcass ply 10 so that they are now rests on the outer surface of the drum 3.
