Description
Drahtvorschubmechanismus für Metallspritzpistolen Als bekannt wird vorausgesetzt, daß der Drahtvorschub in Metallspritzpistolen durch eine irgendwie angetriebene Transportrolle vorwärts bewegt wird. Weiterhin ist bekannt, daß die den Draht gegen die Transportrolle drückende Druckrolle ebenfalls, beispielsweise durch Zahnräder angetrieben, als Transportrolle mitwirkt. Die Nachteile dieser Bauweise liegen darin, daß bei Verbiegungen des Drahtes oder sonstwie auftretender Bremswirkungen der Drahtvorschub ungleichmäßig wird oder sogar unterbleibt. Selbst die als Transportrolle ausgebildete Druckrolle behebt diese Schwierigkeiten nicht.Wire feed mechanism for metal spray guns as is known provided that the wire feed in metal spray guns is through some sort of driven transport roller is moved forward. It is also known that the The pressure roller pressing the wire against the transport roller also, for example driven by gears, acts as a transport roller. The disadvantages of this design lie in the fact that when the wire is bent or braking effects occur in some other way the wire feed becomes uneven or even does not occur. Even as a transport role trained pressure roller does not solve these difficulties.
Der Zweck der neuen Erfindung ist, daß der Draht über zwei hintereinanderliegende angetriebene Transportrollen geführt wird, wodurch eine höhere Friktion erreicht ist und damit ein sicherer Vorschub gewährleistet wird. Durch das Wirken dieser beiden Rollen werden Unebenheiten im Draht ausgeglichen, weil mindestens immer eine Rolle im Zug ist und dadurch das sehr nachteilige ruckartige Arbeiten vermieden wird.The purpose of the new invention is that the wire over two consecutive driven transport rollers is guided, whereby a higher friction is achieved is and thus a safe feed is guaranteed. By working this both rollers compensate for unevenness in the wire, because there is always at least one Role is in the train and thus avoided the very disadvantageous jerky work will.
Die Zahl der angetriebenen Transportrollen kann bei Bedarf beliebig erhöht werden.The number of driven transport rollers can be arbitrary if necessary increase.
Zur weiteren Erhöhung der Friktion und zum Ausgleich der Unebenheiten dies Drahtes können die Transportrollen mit Gummi oder anderen elastischen Stoffen mit hohen Reibungskoeffizienten ausgerüstet werden.To further increase the friction and to compensate for unevenness this wire can transport rollers with rubber or other elastic materials be equipped with a high coefficient of friction.
Durch den Einbau von Laufrollen (nicht angetriebene Rollen beliebigen Durchmessers) vor und zwischen den Transportrollen und geeignet vieler Druckrollen wird der Draht gerichtet und schiebt sich so leichter und gleichmäßiger durch die Düse.By installing rollers (non-driven rollers any Diameter) in front of and between the transport rollers and a suitable number of pressure rollers the wire is straightened and slides easier and more evenly through the Jet.
Zur weiteren Erhöhung der Friktion kann man über die Transport- und Laufrollen ein endloses, biegsames Band, beispielsweise aus Gummi, legen und erreicht hierdurch eine solche Sicherheit des Vorschubes, daß jede normal auftretende betriebliche Beeinträchtigung des Vorschubes überwunden wird.To further increase the friction you can use the transport and Rolling an endless, flexible tape, e.g. made of rubber, place and thereby achieves such a security of the advance that every normal occurring operational impairment of the feed is overcome.
Weiterhin können eine oder mehrere Rollen des Druckrollensystems (zum Anpressen des Drahtes an die Transport- und Laufrollen) angetrieben werden. Über dieses Druckrollensystem kann dann ebenfalls ein flexibles Band gelegt werden.Furthermore, one or more roles of the pressure roller system (for Pressing the wire against the transport and running rollers). Above this pressure roller system can then also be laid with a flexible tape.
Die endlosen flexiblen Bänder aus Gummi, Textilien oder Metall können auf ihrer Oberfläche zum Transport dies Drahtes mit in Form und Baustoff geeigneten dicht aneinanderliegenden Segmenten bestückt sein. Diese Segmente können aber auch gleichzeitig so ausgebildet sein, daß sie eine Gliederkette darstellen ähnlich den Raupenketten eines Raupenschleppers, nur daß hier ein Profil zur Aufnahme des Drahtes eingearbeitet ist.The endless flexible bands made of rubber, textiles or metal can on its surface for transporting this wire with a suitable shape and building material be populated closely spaced segments. However, these segments can also at the same time be designed so that they represent a link chain similar to the Crawler chains of a caterpillar tractor, only here a profile for receiving the wire is incorporated.
