Description

Verfahren und Vorrichtung zur Herstellung von Hohlkörpern aus thermoplastischem MaterialMethod and device for the production of Hollow bodies made of thermoplastic material

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Hohlkörpern, insbesondere Flaschen, bei dem ein Stück eines aus einem Spritzkopf austretenden Schlauches aus thermoplastischem Material vom Spritzkopf abgetrennt und innerhalb einer zwei- oder mehrteiligen Form mit Druckluft aufgeweitet wird, und auf eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for producing hollow bodies, in particular bottles, in which a piece a hose made of thermoplastic material emerging from a spray head is separated from the spray head and is expanded within a two-part or multi-part mold with compressed air, and on a device for implementation of the procedure.

Es ist bereits ein Verfahren zur Herstellung von Hohlkörpern in Blasformen bekannt, bei dem Kunststoff in einem Schneckenextruder plastifiziert wird. Von einem Extruderkopf dieses Schneckenexfcruders führen Leitungen zu einer Anzahl von Blasformvorrichtungen, in denen die gewünschten Hohlkörper hergestellt werden sollen. Die StrÖmungsv/ege des plastifiziert en Materials vom Schneckenextruder zu den einzelnen Blasform-A method for producing hollow bodies in blow molds is already known, in which the plastic is used in a screw extruder is plasticized. Lines lead from an extruder head of this screw extruder to a number of blow molding devices, in which the desired hollow bodies are to be produced. The flow paths of the plasticized Material from the screw extruder to the individual blow molding

109834/1462109834/1462

Vorrichtungen sind relativ lang. Auf diesem Weg kühlt sich das plastifizierte Material entweder ungünstig ab und kann nicht mehr zufriedenstellend verformt werden oder es muß anfangs im Schneckenextruder so stark überhitzt werden, daß eine Verschlechterung der Materialeigenschaften eintritt. Kit diesem bekannten Verfahren gelangt man daher nicht zu einer wirtschaftlichen Produktion von in ihren Eigenschaften zufriedenstellenden Kunststoffkörpern.Devices are relatively long. This cools you down the plasticized material is either unfavorable and can no longer be deformed satisfactorily or it must initially overheat so much in the screw extruder that a deterioration in the material properties entry. Kit of this known method therefore does not lead to an economical production of plastic bodies which are satisfactory in terms of their properties.

P Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erläuterten Art und eine Vorrichtung zur Durchführung des Verfahrens zu schaffen, welche einfach und wirtschaftlich sind und eine hohe Produktionskapazität aufweisen und die Herstellung von Kunststoffhohlkörpern mit zufriedenstellenden Eigenschaften gewährleisten.The invention is based on the object of a method of the type explained at the outset and a device for Implementation of the process to create which are simple and economical and a high production capacity have and the production of plastic hollow bodies with satisfactory properties.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß mehrere Blasmaschinen verwendet werden und daß alle Maschinen von einer gemeinsamen Einrichtung zur Speisung des thermoplastischen Materials versorgt werden.This object is achieved according to the invention in that several blow molding machines are used and that all machines are supplied by a common device for feeding the thermoplastic material.

* Bei dem erfindungsgemäßen Verfahren wird das Kunststoffmaterial jeweils erst in einer der verwendeten Blasmaschinen plastifiziert und bereits am Ausgang der Blasmaschine in einer Blasform zu einem Hohlkörper verarbeitet. Dadurch ergeben sich für das plastifizierte Material äußerst kurze Strömungswege, so daß das Material, um bis zu den Blasdüsen hin ausreichend flüssig zu bleiben, nicht überhitzt werden muß. Bei dem erfindungsgemäßen Verfahren erfolgt die Zufuhr des Kunatstoffmaterials, insbesondere Kunststoffgranulate zu den einzelnen Blasmaschinen mittels einer gemeinsamen Einrichtung. Das* In the method according to the invention, the plastic material each plasticized only in one of the blow molding machines used and already at the exit of the blow molding machine processed in a blow mold to form a hollow body. This results in extremely short flow paths for the plasticized material, so that the material to to remain sufficiently fluid up to the air nozzles, does not have to be overheated. In the method according to the invention, the plastic material is supplied, in particular plastic granulates for the individual blow molding machines by means of a common facility. That

Kunststoffgranulat kann dann in Granulatform den einzelnen Blasmaschinen zugeführt und erst dort plastifiziert werden. Das erfindurigsgeraäße Yerfahren ist einfach und wirtschaftlich und im Betrieb sehr zuverlässig.Plastic granules can then be given to the individual in granule form Blow molding machines are fed and only then plasticized. The inventive method is simple and economical and very reliable in operation.

Eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens ist mit Vorteil so ausgebildet, daß alle nebeneinanderstehenden Blasmaschinen von einer gemeinsamen Vorrichtung zur Einspeisung des thermoplastischen Materials versorgt werden.A device for carrying out the method according to the invention is advantageously designed so that all standing next to one another Blow molding machines from a common device for feeding in the thermoplastic material are supplied.
