Description

Reifenaufbaumaschine mit einer Wickeltrommel und einer oder mehreren sich über den Trommelumfang erstreckenden, abrollbaren Schraubenfedern Die Erfindung bezieht sich auf eine Reifenaufbaumaschine mit einer Wickeltrommel und einer oder mehreren von über den Trommelumfang verteilt angeordneten Hebeln oder Segmenten gehaltenen, sich über den Trommelumfang erstreckenden, abrollbaren Schraubenfedern zum Verformen und Anlegen des Reifengewebes, die in an den Hebeln oder Segmenten angeordneten Lagerstellen gelagert sind, die die Schraubenfedern umfassen. Tire building machine with a winding drum and one or more Rollable coil springs extending over the circumference of the drum The invention refers to a tire building machine with a winding drum and an or several levers or segments distributed over the circumference of the drum held, extending over the drum circumference, rollable coil springs for deforming and applying the tire fabric, which is attached to the levers or segments arranged bearing points are stored, which include the coil springs.

Die sich bei der Verformung und beim Anlegen des Reifengewebes abrollenden Schraubenfedern haben den Vorteil, daß sie sich dehnen und somit auf verschiedene Durchmesser einstellen können, jedoch bietet die Lagerung der Schraubenfedern an den Hebeln oder Segmenten besondere Schwierigkeiten. Es wurde schon vorgeschlagen, mit Schraubenfederabschnitten aus festem Werkstoff bestehende Lagerkörper zu verbinden, die an den Hebeln oder Segmenten der Reifenaufbaumaschine gelagert sind. The unrolling during the deformation and when the tire fabric is put on Coil springs have the advantage that they stretch and thus to different Can adjust the diameter, but offers the storage of the coil springs the levers or segments have particular difficulties. It has already been suggested to connect existing bearing bodies with coil spring sections made of solid material, which are mounted on the levers or segments of the tire building machine.

Die Verwendung dieser zusätzlichen Lagerkörper kann jedoch Nachteile mit sich bringen; einmal müssen die Schraubenfederabschnitte sicher mit den Lagerkörpern verbunden werden, außerdem ist die zusätzliche Verwendung der Lagerkörper bei manchen Maschinen aufwendig.However, the use of these additional bearing bodies can have disadvantages entail; once the coil spring sections need to be securely attached to the bearing bodies are connected, in addition, the additional use of the bearing body is with some Machines consuming.

Es ist ferner bekannt, an den Hebeln, welche die Schraubenfedern führen sollen, tonnenförmige Lagerkörper zu befestigen, die sich innerhalb der Schraubenfedern befinden bzw. von den Windungen der Wendelfeder umschlossen sind. Dabei ist eine ordnungsgemäße Abrollbewegung der Schraubenfeder nicht möglich, weil die Hebel zwischen zwei benachbarten Windungen der Feder hindurchgeführt werden müssen. It is also known to the levers which the coil springs should lead to attach barrel-shaped bearing bodies, which are located within the coil springs are located or are enclosed by the turns of the helical spring. There is one proper rolling movement of the coil spring is not possible because the levers between two adjacent turns of the spring must be passed through.

Durch die Erfindung soll die Halterung und Lagerung der Schraubenfedern vereinfacht werden und zudem durch die Halterung an den Hebeln oder Segmenten die Abrollmöglichkeit nicht eingeschränkt werden. Dieses wird erfindungsgemäß dadurch erreicht, daß der Durchmesser der Schraubenfedern im Bereich der Lagerstellen kleiner ist. Das Maß der Verkleinerung ist vorzugsweise so gewählt, daß bei einer Abrollbewegung der Schraubenfedern lediglich die Schraubenfedern die Anlegebewegung ausführen. The invention is intended to hold and support the coil springs be simplified and also by the bracket on the levers or segments Unrolling options are not restricted. According to the invention, this is thereby achieved achieved that the diameter of the coil springs in the area of the bearings is smaller is. The degree of reduction is preferably chosen so that during a rolling movement of the coil springs, only the coil springs perform the application movement.

Eine so ausgebildete Feder kann sich über den gesamten Umfang der Reifenwickeltrommel erstrecken, sie besteht aus Abschnitten mit größerem Windungsdurchmesser und im Bereich der Lagerstellen an den Hebeln oder Segmenten aus Abschnitten mit geringerem Außendurchmesser. Ferner kann sie ohne weiteres aus einer endlichen Schraubenfeder gebildet werden deren Länge dem Außendurchmesser der Wickeltrommel angepaßt ist und deren Enden miteinander verbunden werden. A spring formed in this way can extend over the entire circumference of the Extend tire winding drum, it consists of sections with a larger winding diameter and in the area of the bearings on the levers or segments from sections with smaller outside diameter. Furthermore, it can easily consist of a finite helical spring are formed whose length corresponds to the outer diameter of the Winding drum is adapted and whose ends are connected to each other.

Weitere Einzelheiten der Reifenaufbaumaschine werden an Hand der Zeichnung erläutert, in der ein Ausführungsbeispiel dargestellt ist. Es zeigt Fig. 1 eine Reifenwickeltrommel mit hohltrommelartigen Schiebekörpern zur Bearbeitung und Verformung des Reifengewebes in der Teilansicht, Fig. 2 eine Stirnansicht der Schiebekörper nach Fig. 1, Fig. 3 einen Schnitt nach der Linie III-III von Fig. 1, Fig. 4 einen Schnitt nach der Linie IV-IV von Fig. 1 und Fig. 5 einen Abschnitt einer für die Schiebekörper gemäß Fig. 1 und 2 bestimmten Schraubenfeder. Further details of the tire building machine are given on the basis of Drawing explained in which an embodiment is shown. It shows Fig. 1 a tire winding drum with hollow drum-like slide bodies for processing and deformation of the tire fabric in partial view, FIG. 2 is an end view of FIG Sliding body according to FIG. 1, FIG. 3 shows a section along the line III-III of FIG. 1, FIG. 4 shows a section along the line IV-IV of FIG. 1 and FIG. 5 shows a section a coil spring intended for the sliding body according to FIGS.

Eine Wickeltrommell, die im Durchmesser veränderbar ist, wird an beiden Enden von hohltronnnelartigen Schiebekörpern 2 umschlossen, die aus über den Trommelumfang verteilt angeordneten Segmenten 3 bestehen und in Richtung des Pfeiles 4 derart bewegbar gelagert sind, daß sie von den Stirnseiten der Wickeltrommel 1 her die Wickeltrommel 1 umfassend axial verschoben werden können. A winding drum, which can be changed in diameter, is attached both ends of hollow barrel-like sliding bodies 2 enclosed, which from about the drum circumference arranged distributed segments 3 exist and in the direction of the Arrow 4 are movably mounted in such a way that they are from the end faces of the winding drum 1 ago the winding drum 1 can be axially displaced comprehensively.

Am vorderen Ende der Schiebekörper 2 sind sich ebenfalls über den Trommelumfang erstreckende Schraubenfedern 5 gelagert, die bei einer Bewegung der Schiebekörper 2 in Richtung des Pfeiles 4 die seitlich frei auslaufenden, nicht näher dargestellten Randteile des Karkaßgewebes von unten her erfassen und um die in der Umfangsnut 6 der Wickeltrommel 1 befindlichen Wulstkerne herumführen und so auf dem übrigen Teil der Gewebelagen zur Anlage bringen. At the front end of the sliding body 2 are also on the Drum circumference extending coil springs 5 mounted, which upon movement of the Sliding body 2 in the direction of arrow 4, the laterally freely expiring, not capture edge parts of the carcass fabric shown in more detail from below and around the bead cores located in the circumferential groove 6 of the winding drum 1 and so bring it to rest on the remaining part of the fabric layers.

Die Art der Verformung des Reifengewebes ist nicht näher dargestellt.The type of deformation of the tire fabric is not shown in detail.

An den vorderen Enden 7 der Segmente 3 sind zwei Klauenkörper 8 angeschraubt, die vorn eine als Auge ausgebildete Lagerstelle 9 bilden, die die Schraubenfeder 5 umschließt. At the front ends 7 of the segments 3, two claw bodies 8 are screwed, the front form a bearing 9 designed as an eye, which the helical spring 5 encloses.

Die Schraubenfeder 5 weist Abschnitte 5' in dem Bereich zwischen benachbarten Klauenkörpern 8 auf, deren wirksamer Außendurchmesser D größer ist als die Wandstärke der Segmente 3 in ihren der Schraubeufeder 5 zugekehrten Bereichen. Die Klauenkörper 8 bzw. die von ihnen gebildeten Augen umschließen hingegen Abschnitte 5", deren Außendurchmesser d wesentlich kleiner als der Außendurchmesser D und dem lichten Durchmesser des Auges 9 derart angepaßt ist, daß die Schraubenfedern 5 bei Bewegung der hohitrommelartigen Schiebekörper 2 in Richtung des Pfeiles 4 eine Abrollbewegung ausführen können. The helical spring 5 has sections 5 'in the area between adjacent claw bodies 8, the effective outer diameter D of which is larger than the wall thickness of the segments 3 in their areas facing the helical spring 5. The claw bodies 8 or the eyes formed by them, however, enclose sections 5 ", the outer diameter d of which is significantly smaller than the outer diameter D and the inside diameter of the eye 9 is adapted so that the coil springs 5 at Movement of the hollow drum-like sliding body 2 in the direction of arrow 4 is a rolling movement can perform.

Die Schraubenfeder 5 wird als endliche Feder mit den Abschnitten 5' und 5" gewickelt, zu einem Ring gebogen und schließlich durch Verklemmen oder Verlöten ihrer Endwindungen zu einem endlosen Körper gemacht. The coil spring 5 is a finite spring with the sections 5 'and 5 "wrapped, bent into a ring and finally clamped or Soldering their end turns made into an endless body.

Es sei erwähnt, daß die Klauenkörper 8 gegebenenfalls auch durch andere Lagerkörper ersetzt werden können. Auch versteht es sich, daß der Durchmesser d bzw. das Auge 9 so bemessen werden müssen, daß - wie in Fig. 3 dargestellt - der AußendurchmesserD um ein geringes Maß größer als der Außendurchmesser des Auges 9 ist. It should be mentioned that the claw body 8, if necessary, also through other bearing bodies are replaced can. It is also understood that the diameter d or the eye 9 must be dimensioned so that - as shown in Fig. 3 - the Outside diameter D slightly larger than the outside diameter of the eye 9 is.
