Abstract
Vorrichtung zur Reduzierung der für den Blasformprozess erforderlichen Druckluft, gekennzeichnet dadurch, dass an dem für die Entlüftung des Werkzeuges (2) vorgesehenen Schnellentlüftungsventil (4) eine Schnittstelle (15) und ein Druckspeicher (5) sowie zum Befüllen und Entleeren des Druckspeichers (5) ein Ventil (7) angeordnet ist.Apparatus for reducing the compressed air required for the blow molding process, characterized in that an interface (15) and a pressure accumulator (5) and for filling and emptying the pressure accumulator (5) are provided on the quick exhaust valve (4) provided for the venting of the tool (2). a valve (7) is arranged.
Description
Zur Reduzierung der für den Blasformprozess erforderlichen Blasluft sind aus dem Stand der Technik Lösungen bekannt.to Reduction of the blow molding process required Blown air are known from the prior art solutions.
In
All die vorschlagen technischen Lösungen haben das Ziel, die Prozessluft nach dem Formvorgang in einer Niederdruckleitung zuzuführen bzw. damit Antriebselemente mit niederem Druckwert zu betreiben. Der wesentlichste Nachteil dieser Lösungen besteht darin, dass der technische Aufwand sehr hoch und eine Nachrüstung bestehender Anlagen nicht möglich ist.Alles the propose technical solutions have the goal that Supply process air after molding in a low pressure line or thus to operate drive elements with low pressure value. The most significant disadvantage of these solutions is that the technical effort is very high and a retrofit existing facilities is not possible.
Ziel der Erfindung ist es, eine technisch einfache Lösung vorzuschlagen mit der es möglich ist, die nicht mehr benötigte Druckluft nach dem Formprozess für den folgenden Arbeitsprozess zu nutzen und eine kostengünstige Nachrüstung bereits bestehender Anlagen zu gewährleisten.aim The invention is to propose a technically simple solution with which it is possible the no longer needed Compressed air after the molding process for the following work process to use and a cost-effective retrofit already existing facilities.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, mit der es ermöglicht wird, die für den Ausformprozess von Kunststoffhohlkörpern mittels Blasformmaschinen erforderliche Druckluftenergie derart zu reduzieren, das eine ein qualitätsgerechtes Ausformen gewährleistet wird und ein Teil dieser Energie für den nachfolgenden Ausformprozess wieder verwendet werden kann, wobei eine negative Beeinflussung der Taktzeit der Anlage vermieden wird.Of the Invention has for its object to provide a device which makes it possible for the molding process of plastic hollow bodies by means of blow molding required compressed air energy to reduce this, the one a quality-oriented molding is guaranteed and part of this energy for the subsequent molding process can be reused, with a negative influence on the cycle time of the system is avoided.
Die
Aufgabe wird erfindungsgemäß dadurch gelöst,
dass die bisherige für den Blasformprozess erforderliche
Druckluft über geeignete, vorzugsweise Ventile (
Das Anwendungsgebiet der erfindungsgemäßen Vorrichtung ist vorzugsweise die nachträgliche Ausrüstung oder direkte Integration an Blasformanlagen zur Herstellung von Kunststoffhohlkörper in der kunststoffverarbeitenden IndustrieThe Field of application of the device according to the invention is preferably the retrofitting equipment or direct integration with blow molding equipment for the production of Plastic hollow bodies in the plastics processing industry
Die erfindungsgemäße Vorrichtung soll nachfolgend an einem Ausführungsbeispiel näher erläutert werden.The Device according to the invention is intended below explained in more detail in one embodiment become.
