Abstract

Zum Einschneiden eines Ventilloches und Aufrauhen der Umgebungsfläche eines Luftschlauches in einem einzigen Arbeitsgang dient erfindungsgemäß eine Rauh- und Schneidvorrichtung mit einer auf den in einer Halterung (1) liegenden flachen Schlauch (4) absenkbaren, kreisförmigen Rauhscheibe (9), die in ihrem Zentrum einen nach unten herausragenden Schneidansatz (11) mit einer Höhe entsprechend der Dicke einer Schlauchwandung (5) zum Einschneiden des Ventilloches (12) trägt.To cut a valve hole and roughen the surrounding surface of an air hose in a single operation, a roughening and cutting device is used according to the invention with a circular roughening disc (9) which can be lowered onto the flat hose (4) located in a holder (1) and which has a downwardly protruding cutting attachment (11) with a height corresponding to the thickness of a hose wall (5) for cutting the valve hole (12).

Description

Die Erfindung betrifft eine Rauh- und Schneidvorrichtung für Luftschläuche, insbesondere für Fahrradreifen, zum Einschneiden eines Ventilloches und Aufrauhen der Umgebungsfläche.The invention relates to a roughening and cutting device for air tubes, in particular for bicycle tires, for cutting a valve hole and roughening the surrounding area.

Bei Fahrradschläuchen mit anvulkanisierten Gummifußventilen war es bisher üblich, Schlauch und Gummifuß des Ventils im noch unvulkanisierten Zustand zusammenzubringen und gemeinsam auszuvulkanisieren.In the case of bicycle tubes with vulcanized rubber foot valves, it was previously common to use a tube and a rubber foot of the valve in the still unvulcanized state and vulcanize out together.

Bei einer Schlauchfertigung, bei der der Schlauch endlos auf einem Extruder gespritzt und anschließend kontinuierlich, beispielsweise im Salzbad vulkanisiert wird, um anschließend auf Fertigungsmaßabschnitte zugeschnitten und konfektioniert zu werden, ergeben sich jedoch Schwierigkeiten um eine feste Verbindung zwischen dem Gummifußventil und dem bereits ausvulkanisierten Schlauch zu erreichen, da ein herkömmliches Aufkleben mit einer entsprechenden Gummilösung nicht die erforderliche Dauerfestigkeit bringt.In hose production where the hose is continuously injected onto an extruder and then is vulcanized continuously, for example in a salt bath, and then cut to size sections and to be assembled, however, difficulties arise around a fixed connection between the rubber foot valve and the already vulcanized hose, as a conventional one Gluing on with an appropriate rubber solution does not bring the required fatigue strength.

Bei einem derartigen Herstellungsverfahren ist es daher erforderlich, an der Aufsatzstelle des Gummifußventils ein entsprechendes Ventilloch in eine Wandung des Schlauches zu schneiden und die Umgebung dieses Ventilloches für das Anvulkanisieren des Gummifußventils entsprechend aufzurauhen.In such a manufacturing process, it is therefore necessary at the attachment point of the rubber foot valve to cut a corresponding valve hole in a wall of the hose and the area surrounding it Roughen the valve holes for the vulcanization of the rubber foot valve accordingly.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zu schaffen mit der es möglich ist, das Aufrauhen des Schlauches und das Einschneiden des Ventiles in ein und demselben Arbeitsgang durchzuführen.The invention is therefore based on the object of creating a device with which it is possible to roughen of the hose and the cutting of the valve in one and the same operation.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß eine auf den in einer Halterung liegenden flachen Schlauch absenkbare, kreisförmige Rauhscheibe vorgesehen ist, die in ihrem Zentrum einen nach unten herausragenden Schneidansatz mit einer Höhe entsprechend der Dicke der Schlauchwandung zum Einschneiden des Ventilloches trägt.To solve this problem, the invention provides that one lying in a holder Flat hose lowerable, circular roughing disc is provided, which has a downward in its center protruding cutting attachment with a height corresponding to the thickness of the hose wall for cutting of the valve hole.

Damit ist es auf einfache Weise möglich, an einer beliebigen Stelle des Schlauchumfangs ein Ventilloch nur einseitig in den Schlauch zu schneiden.This makes it possible in a simple manner to create a valve hole at any point on the hose circumference to cut into the tube only on one side.

Anhand einer schematischen Zeichnung sind Aufbau und Wirkungsweise eines Ausführungsbeispiels nach der Erfindung näher erläutert. Dabei zeigtA schematic drawing shows the structure and mode of operation of an exemplary embodiment the invention explained in more detail. It shows

F i g. 1 eine schematische Seitenansicht einer Rauh- und Schneidvorrichtung für das Ventilloch,F i g. 1 is a schematic side view of a roughening and cutting device for the valve hole,

F i g. 2 einen Längsschnitt durch einen Schlauchabschnitt im Fertigzustand im Bereich des Ventilloches undF i g. 2 shows a longitudinal section through a tube section in the finished state in the area of the valve hole and

F i g. 3 eine Aufsicht auf diesen Schlauchabschnitt mit der aufgerauhten Stelle und dem Ventilloch.F i g. 3 shows a plan view of this hose section with the roughened point and the valve hole.

Wie aus Fig. 1 zu ersehen ist, wird auf eine flache Halterung 1 mit zwei Anschlägen 2 und 3 an der hinteren Kante der Halterung 1 ein Schlauch 4 mit Schlauchoberseite 5 und Schlauchunterseite 6 im praktisch luftlosen Zustand so aufgelegt, daß er bündig an den beiden Anschlägen 2 und 3 anliegt. Die korrekte Lage des Schlauches wird dabei durch zwei Photozellen 7 und 8 überwachtAs can be seen from Fig. 1, a flat bracket 1 with two stops 2 and 3 on the rear Edge of the holder 1 is a tube 4 with a tube top 5 and a tube bottom 6 in a practically airless manner State placed in such a way that it is flush with the two stops 2 and 3. The correct position of the The hose is monitored by two photocells 7 and 8

Oberhalb des so in Position gebrachten Schlauches 1Above the hose 1 that has been positioned in this way

ist nunmehr eine ebene, kreisförmige Rauhscheibe 9 über einen Stempel 10 absenkbar gehalten, die die Schlauchoberseite 5 im Bereich des aufzubringenden Gummifußventils aufrauht Gleichzeitig trägt diese Rauhscheibe 9 im Zentrum einen Schneidansatz 11, der maximal die Höhe entsprechend der Dicke der oberen Schlauchwandung 5 aufweist Nach Absenken der Rauhscheibe 9 wird somit ein Ventilloch geschnitten und die Schlauchoberseite 2 entsprechend aufgerauhtis now a flat, circular rough wheel 9 held lowerable via a punch 10, which the The upper side of the hose 5 roughened in the area of the rubber foot valve to be applied. At the same time, it is worn Roughing wheel 9 in the center has a cutting attachment 11 which has at most the height corresponding to the thickness of the upper hose wall 5 After lowering the Rough disk 9 is thus cut a valve hole and the tube top 2 is roughened accordingly

Der fertige Schlauchabschnitt ist in den F i g. 2 und 3 gezeigt Dabei erkennt man das in die Schlauchoberseite 5 eingeschnittene Ventilloch 12 sowie den kreisförmig aufgerauhten Bereich 13 in der Umgebung des Ventilloches 12, auf den anschließend das eigentliche Gummifußventil 14 mit seiner Unterseite 15 aufgesetzt und anvulkanisiert wird.The finished tube section is shown in FIGS. 2 and 3 shown here you can see that in the upper side of the hose 5 incised valve hole 12 and the circular roughened area 13 in the vicinity of the valve hole 12, on which the actual rubber foot valve 14 is then placed with its underside 15 and is vulcanized.

Mit der beschriebenen Vorrichtung ist es also auf einfache Weise möglich, in einem einzigen Arbeitsgang bei aufeinanderliegendem Schlauch ein Ventilloch in nur eine Wandung des Schlauches einzuschneiden und gleichzeitig die Umgebung des Ventil'oches aufzurauhen. With the device described, it is thus possible in a simple manner, in a single operation cut a valve hole in only one wall of the hose when the hose is lying on top of one another and to roughen the area around the valve hole at the same time.
