Zur Überwindung des zuvorgenannten Problems ist es bekannt die Heizleistung des Heizaggregates und damit die Wärme des Heißluftstromes bei Schweißunterbrechungen herunterzuregeln. Dieses bekannte Verfahren hat jedoch ebenfalls Nachteile. Zum Einen ist eine derartige Heizregelung aufwendig und von daher nachteilig. Zum Zweiten wird bei der zuvorgenannten Lösung des Problems die Temperatur im Extruderabschnitt ebenfalls beeinflußt, was sich nachteilig auf die Extruderwirkung, sowohl hinsichtlich der Ausstoßmenge als auch der Qualität des Schweißmaterials auswirken kann.To overcome of the aforementioned problem, it is known the heating power of Heating units and thus the heat of the hot air stream down during welding breaks. This known However, the method also has disadvantages. For one thing is such Heating control consuming and therefore disadvantageous. Second is in the aforementioned solution of the problem the temperature also influenced in the extruder section, which is disadvantageous on the extruder effect, both in terms of output as well as the quality of the welding material can.
Aufgabe der vorliegenden Erfindung ist es die Nachteile des zuvorgenannten Standes der Technik zu überwinden und eine Heissluftführung für einen Schweißextruder bereit zu stellen, bei dem eine Überhitzung des Schweißmaterials im Düsenrohr vermieden wird, wobei gleichzeitig die Erwärmung der Werkstücke ermöglicht wird. Weitere Teilaufgabe der vorliegenden Erfindung ist es eine Vorrichtung der zuvor genannten Art bereitzustellen, wobei auf eine Regelung der Heizleistung für den Heissluftstrom verzichtet werden kann. Weitere Teilaufgabe ist es, eine Vorrichtung der zuvorgenannten Art bereit zu stellen, bei der der Schweißschuh um 360° drehbar ist, wobei gleichzeitig die Zuleitung des Heissluftstromes auf die Werkstücke gewährleistet bleibt.task The present invention is the disadvantages of the aforementioned Prior art overcome and a hot air duct to provide for a welding extruder which prevents overheating of the welding material in the nozzle tube while at the same time heating the workpieces is possible. Further subtask of the present invention is it to provide a device of the aforementioned kind, with a regulation of the heating power for the hot air flow can be waived. Another subtask is a device of the aforementioned type, in which the welding shoe is rotatable by 360 °, at the same time the supply of the Hot air flow ensured on the workpieces remains.
Gelöst werden die Aufgaben nach den technischen Merkmalen des unabhängigen Anspruches. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen dargestellt.Solved The tasks are based on the technical characteristics of the independent Claim. Preferred embodiments are in the dependent Claims presented.
Die Erfindung geht von einem Schweißextruder bekannter Art aus, welcher über eine Heisslufteinrichtung verfügt. Es ist nicht erfindungswesentlich, ob die Heisslufteinrichtung sowohl den Extruder als auch nachfolgend das Werkstück erwärmen soll, oder ob die Heisslufteinrichtung ausschließlich zur Erwärmung der Werkstücke herangezogen wird.The Invention is based on a welding extruder of known type off, which has a hot air device. It is not essential to the invention, whether the hot air device both heat the extruder as well as subsequently the workpiece should, or whether the hot air device exclusively for heating the workpieces is used.
Die Erfindung geht den Weg die vom Heißluftmodul der Heißlufteinrichtung zugeleitete Heissluft vom Düsenrohr physikalisch zu trennen, wobei gleichzeitig die freie Drehbarkeit des Schweißschuhes mit angeordneter Heißluftdüse um 360 gewährleistet wird. Zu diesem Zwecke wird die Heissluft des Heissluftmoduls in eine Ringleitung geleitet, welche den betroffenen Düsenrohrabschnitt umläuft. Durch diesen Kunstgriff wird ein direkter Kontakt der Heissluft mit dem Düsenrohr verhindert und eine Überhitzung des im Düsenrohr befindlichen Thermoplasten verhindert.The invention goes the way to physically separate the hot air supplied from the hot air module of the hot air device from the nozzle tube, while at the same time guaranteeing 360 ° free rotation of the welding shoe with the hot air nozzle arranged. For this purpose, the hot air of the hot air module is passed into a loop which circulates the affected nozzle tube section. This artifice prevents direct contact of the hot air with the nozzle tube and overheating of the thermoplastic located in the nozzle tube prevented.
Die Ringleitung ist erfindungsgemäß weiterhin als Profil ausgebildet, das wenigstens in Richtung auf den Schweißschuh offen gehalten ist. Die Abdichtung erfolgt durch eine drehbare Deckelscheibe die das Profil in Richtung auf den Schweißschuh abdichtet. Weiterhin weist die Deckelscheibe einen Durchbruch auf, durch den die Heißluft in die Heißluftdüse abströmen kann. Geeigneter weise kann die Heißluftdüse unmittelbar an der genannten Deckelscheibe angeordnet sein. In dieser Ausführungsform bilden Heißluftdüse, Schweißschuh und Deckelscheibe eine bauliche Einheit. Letzteres wird nachfolgend noch erläutert.The Ring line is still according to the invention as Profile formed, at least in the direction of the welding shoe kept open. The seal is made by a rotatable cover disc which seals the profile in the direction of the welding shoe. Furthermore, the cover plate on a breakthrough, through the discharge the hot air into the hot air nozzle can. Suitably, the hot air nozzle can immediately be arranged on the said cover plate. In this embodiment make hot air nozzle, welding shoe and Cover disc a structural unit. The latter will be below explained.
Das Profis kann als U- oder L-Profil ausgeführt sein. In der Ausführungsform als U-Profil ist dieses so angeordnet, das die offene Seite in Richtung auf den Schweißschuh gerichtet ist. Der Abschluss erfolgt dann durch die Deckelscheibe. In der Ausführungsform als L-Profil ist dieses so angeordnet, das der eine Schenkel die Außenseite der Ringleitung und der zweite Schenkel die Seite und den Abschluß gegenüber der Extruderseite bildet. Die dem Schweißschuh zugewandte Seite der Ringleitung wird durch Deckelscheibe gebildet. Die dem Düsenrohr zugewandte Seite wird durch einen ringförmigen Steg gebildet, der auf der Deckelscheibe angeordnet ist. Mit anderen Worten wird in dieser zuletzt genannten Ausführungsform die Ringleitung durch zwei gegeneinandergesetzte L-Profile gebildet, wobei das innere L-Profil durch die Deckelscheibe und den darauf angeordneten ringförmigen Steg gebildet wird.The Professionals can be designed as a U or L profile. In the Embodiment as a U-profile, this is arranged so the open side is directed towards the welding shoe is. The conclusion then takes place through the cover disc. In the Embodiment as L-profile, this is arranged so the one leg the outside of the loop and the second leg the side and the conclusion opposite forms the extruder side. The the welding shoe facing Side of the loop is formed by cover disc. The the Nozzle tube facing side is through an annular web formed, which is arranged on the cover disc. With others Words will in this last-mentioned embodiment the loop is formed by two opposing L-profiles, wherein the inner L-profile through the cover plate and arranged thereon annular web is formed.
Die Deckelscheibe mit ggf. darauf, angeordnetem Schweißschuh und Heissluftdüse kann mit üblichen Mitteln drehbar an dem Handscheißextruder befestigt werden. Eine Möglichkeit besteht in der Verwendung einer Überwurfmutter deren überkragender Rand die Deckelscheibe hintergreift und in geeigneter Weise an dem Gehäuse des Schweißextruders befestigt wird. Eine andere Möglichkeit besteht darin an sich bekannte Verriegelungselemente am Düsenrohr vorzusehen, die in den Scheißschuh eingreifen, wobei in letzterer Ausführungsform der Schweißschuh, die Heißluftdüse und die Deckelscheibe eine bauliche Einheit bilden.The Lid with possibly arranged thereon welding shoe and hot air nozzle can be rotated by conventional means be attached to the hand impact extruder. A possibility is the use of a union nut whose overhanging edge the cover disc engages behind and in a suitable manner to the housing the welding extruder is attached. Another possibility There is known per se locking elements on the nozzle tube be provided, which engage in the shit shoe, in the latter embodiment of the welding shoe, the Hot air nozzle and the cover disc a structural Form unity.
Die Erfindung wird nachfolgen anhand der Figuren erläutert, welche eine bevorzugte Ausführungsform zeigen. Bei der dargestellten Ausführungsform wird die Ringleitung durch zwei L-Profile gebildet, wie zuvor im Grundsatz erläutert. Wobei:The Invention will be explained below with reference to the figures, which show a preferred embodiment. In the illustrated embodiment, the loop is through formed two L-profiles, as previously explained in principle. In which:
