Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum automatisierten Schneiden von Kombinationsbauteilen aus zumindest einer Bahn aus in eine Kautschukmischung eingebetteten zueinander parallel verlaufenden Festigkeitsträgern und zumindest einem mit der Bahn teilweise überlappenden Profil aus einer Kautschukmischung, insbesondere zum Herstellen abgelängter Reifenbauteile, welche anschließend auf eine Aufbautrommel aufgelegt und gespleißt werden.The The invention relates to a method and an apparatus for automated Cutting of combination components of at least one web in a rubber compound embedded mutually parallel reinforcing materials and at least one profile partially overlapping the web from one Rubber mixture, in particular for producing cut-to-length tire components, which subsequently be placed on a building drum and spliced.
Bei der Herstellung von Fahrzeugluftreifen werden zur Rationalisierung des Reifenaufbaus verstärkt vorkonfektionierte Kombinationsbauteile eingesetzt. Zu diesen Kombinationsbauteilen zählt beispielsweise das mit dem Stahlkordwulstverstärker kombinierte Wulstprofil. Derzeit ist es üblich, diese Kombinationsbauteile händisch abzulängen, beispielsweise mit einem Reisshaken, welcher das Bauteil zwischen zwei Festigkeitsträgern auseinander trennt. Mit einem händischen Schneiden ist eine gerade Schnittkante nur schwer erzeugbar. Zudem sind beim Schneidvorgang Stich- und/oder Schnittverletzungen durch den Stahlkord häufig. Es ist ferner bekannt, zum Schneiden von Profilen aus Kautschukmischungen Rollenmesser, Ultraschallmesser, Guillotinemesser oder Laser einzusetzen. Die Verwendung von Rollenmessern zum Schneiden von Kombinationsbauteilen scheitert daran, dass mit einem Rollenmesser nur ein sehr geringer Anstellwinkel relativ zur Bauteiloberfläche möglich ist, der für den Schnitt im Stahlkord enthaltenden Bauteil gewählte Anstellwinkel müsste auch im Profil beibehalten werden. Zudem ist der wählbare Anstellwinkel bei den üblichen Rollenmessern nicht sehr groß und liegt nahe der Senkrechten zum Schnittgut. Das Kombinationsbauteil könnte daher nur mit einem vergleichsweise geringen Anstellwinkel zugeschnitten werden und in der Folge müsste das Profil aus der Kautschukmischung praktisch stumpf und somit ohne Überlappungen der Enden gespleißt werden.at the manufacture of pneumatic vehicle tires are rationalizing strengthened the tire structure Pre-assembled combination components used. To these combination components counts, for example that combined with the steel cord bead enhancer Bead profile. Currently it is common these combination components by hand cut to length, For example, with a hook, which between the component two reinforcements separates apart. With a manual Cutting a straight cutting edge is difficult to produce. moreover are stabbing and / or cutting injuries during the cutting process the steel cord frequently. It is also known to cut profiles of rubber compounds Roller knife, ultrasonic knife, guillotine knife or laser use. The use of roller knives for cutting combination components fails because with a roller blade only a very small Angle of incidence relative to the component surface is possible, for the cut in the Steel cord containing component selected angle of attack would also need be maintained in the profile. In addition, the selectable angle of attack is the usual roller knives not very big and is close to the vertical to the clippings. The combination component could therefore cut only with a comparatively low angle of attack and in the sequence would have to the profile of the rubber mixture practically dull and thus without overlaps the ends spliced become.
Auch mit einem konventionellen Guillotinemesser lässt sich ein mit Stahlkord verstärktes Bauteil, etwa ein Stahlkordwulstverstärker, nicht optimal schneiden. Es besteht die Gefahr, dass das Messer vom Kord, oder dass der Kord durch das Messer beschädigt wird oder, dass das Messer am Kord hängen bleibt. Auch ein Anstellwinkel, der für einen optimalen Schnitt im Profil erforderlich wäre, lässt sich nicht einstellen.Also with a conventional guillotine knife can be with a steel cord reinforced Component, such as a Stahlkordwulstverstärker, not optimally cut. There is a risk that the knife from the cord, or that the cord damaged by the knife or that the knife gets stuck on the cord. Also an angle of attack, the for an optimal cut in the profile would be required, can not be adjusted.
Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Verfügung zu stellen, mit welchen der Zuschnitt eines Kombinationsbauteils automatisiert und in optimaler Qualität möglich ist.Of the Invention is therefore the object of a method and a Device available to ask, with which the cutting of a combination component automated and in optimal quality is possible.
Was das Verfahren betrifft wird die gestellte Aufgabe erfindungsgemäß dadurch gelöst, dass die Bahn gemeinsam mit dem überlappend verlaufenden Abschnitt des Profils mit einem zumindest eine und in beide Schnittrichtungen wirksamen Klinge aufweisenden erhitzten Messer entlang einer zwischen zwei benachbarten Festigkeitsträgern verlaufenden Schnittlinie senkrecht zur Bahn geschnitten wird und anschließend der ungeschnitten gebliebene Abschnitt des Profils mit einem unter einem wählbaren Anstellwinkel β zur Waagrechten ansetzbaren Doppelklingenmesser geschnitten wird, dessen eine Klinge das Profil quer zu dessen Längserstreckung schneidet und dessen zweite Klinge das Profil beim Ende der zuerst erzeugten Schnittlinie lokal in Längserstreckung durchschneidet.What The method concerns the task according to the invention solved, that the lane together with the overlapping extending section of the profile with at least one and in both cutting directions effective blade having heated Knife along a running between two adjacent reinforcements cutting line is cut perpendicular to the web and then the uncut Section of the profile with a below a selectable angle β to the horizontal attachable double blade knife is cut, one blade of which the profile cuts transversely to its longitudinal extent and its second blade the profile at the end of the first generated Cutting line locally in longitudinal extension cuts.
Die erfindungsgemäße Vorrichtung ist dadurch gekennzeichnet, dass sie eine Kombination aus einem die Bahn senkrecht durchschneidenden zumindest eine Klinge aufweisenden Messer und einem den verbleibenden Abschnitt des Profils unter einem wählbaren Anstellwinkel schneidenden Messer aufweist.The inventive device is characterized in that it is a combination of a the web having perpendicularly intersecting at least one blade Knife and one the remaining section of the profile under one selectable Having pitch angle cutting knife.
Das erfindungsgemäße Verfahren und die erfindungsgemäße Vorrichtung erlauben ein automatisch ablaufendes Ablängen eines Kombinationsbauteils aus zumindest einer Bahn aus in eine Kautschukmischung eingebetteten, parallelen Festigkeitsträgern und aus zumindest einem Profil. Von besonderem Vorteil ist dabei der exakt durchführbare Schnitt, insbesondere in der die Festigkeitsträger enthaltenden Bahn. Handelt es sich um den Zuschnitt von Reifenbauteilen können diese nachfolgend beim Reifenaufbau optimal gespleißt werden, auch das Automatisierungspotenzial bei der Spleißbildung ist wesentlich höher als bei herkömmlichen Schneidmethoden. Darüber hinaus kann der Ausschuss sehr gering gehalten werden. Von besonderem Vorteil ist es auch, dass die Messer optimal auf ihren jeweiligen Schnitt eingestellt werden können.The inventive method and the device according to the invention allow an automatically running cutting to length of a combination component from at least one web embedded in a rubber compound, parallel reinforcements and from at least one profile. Of particular advantage is the exact feasible cut, in particular in the web containing the reinforcement. These it can be the cutting of tire components, these in the following tire construction optimally spliced also the automation potential for splicing is much higher as with conventional Cutting methods. About that In addition, the committee can be kept very low. Of special It is also an advantage that the knives fit perfectly on their respective cuts can be adjusted.

Dabei zeigenFurther Features, advantages and details of the invention will be apparent from of the drawings, which schematically illustrate several embodiments, described in more detail. Show
