Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Mehrschicht-Kunststoffhohlkörpers, insbesondere einer Mehrschicht-Kunststoffflasche im Spritzblasverfahren an vier oder mehr Stationen. Weiterhin betrifft die Erfindung eine Spritzblasmaschine mit vier oder mehr Stationen zur Durchführung des Verfahrens.The The invention relates to a method for producing a multilayer plastic hollow body, in particular a multi-layer plastic bottle by injection blow molding on four or more stations. Furthermore, the invention relates to a Spritzblasmaschine with four or more stations to carry out the process.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der eingangs genannten Art zu schaffen, mit denen auf besonders effektive Weise zwei- bzw. mehrschichtige Kunststoffhohlkörper, insbesondere Kunststoffflaschen hergestellt werden können.Of the Invention is based on the object, a method and an apparatus of the type mentioned above, with which to particular effective way two- or multilayer plastic hollow body, In particular, plastic bottles can be produced.
Die Lösung dieser Aufgabe erfolgt mit einem Verfahren mit den Merkmalen des Patentanspruchs 1. Eine entsprechende Spritzblasmaschine ist im Patentanspruch 6 beschrieben. Bevorzugte Weiterbildungen und Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The Solution to this problem is done with a method with the Features of claim 1. An appropriate injection blow molding machine is described in claim 6. Preferred developments and embodiments of the invention are in the subclaims specified.
In dem Verfahren zur Herstellung eines Mehrschicht-Kunststoffhohlkörpers, insbesondere einer Mehrschicht-Kunststoffflasche, im Spritzblasverfahren an vier oder mehr Stationen, wobei an einer Station thermoplastisches Material eingespritzt wird, ist erfindungsgemäß vorgesehen, dass an einer dem Einspritzen folgenden Station das Blasformen des Kunststoffhohlkörpers erfolgt, dass an einer dem Blasformen folgenden Station ein weiteres thermoplastisches Material zur Bildung einer weiteren Schicht eingespritzt wird und dass an einer folgenden Station die so hergestellten Kunststoffhohlkörper ausgegeben oder entladen werden. Auf diese Weise kann eine Mehrschicht-Kunststoffflasche mit sehr hoher Qualität hergestellt werden. Entscheidend ist, dass zunächst der ein- oder mehrschichtige Vorformling (Preform) zum Hohlkörper geblasen wird und dann auf den bereits ausgeformten Hohlkörper eine zusätzliche Schicht aufgebracht wird.In the method for producing a multilayer plastic hollow body, in particular a multi-layer plastic bottle, by injection blow molding at four or more stations, wherein at one station thermoplastic Material is injected, is provided according to the invention, that at a station following the injection, the blow molding of the hollow plastic body takes place that at a station following the blow molding another thermoplastic material injected to form another layer is and that issued at a subsequent station, the plastic hollow body thus produced or unloaded. In this way, a multi-layer plastic bottle be made with very high quality. critical is that initially the single or multi-layer preform (Preform) is blown to the hollow body and then on the already formed hollow body an additional Layer is applied.
In einer bevorzugten Ausführungsform werden beim ersten Einspritzen zwei oder mehr Materialien eingespritzt und aus diesen wird der Vorformling hergestellt, der dann zum Hohlkörper ausgeformt wird. Erfindungsgemäß wird dann auf den aus mehreren Schichten hergestellten Hohlkörper in der späteren Station eine Außenschicht im Overmoulding-Prozess aufgebracht.In In a preferred embodiment, the first injection injected two or more materials and from these is the Preform produced, which is then formed into a hollow body. According to the invention is then on from several Layers produced hollow body in the later Station applied an outer layer in the overmolding process.
Bevorzugt wird das weitere thermoplastische Material zur Bildung einer Außenhaut auf den Kunststoffhohlkörper aufgespritzt. Dieser Prozess wird auch als Overmoulding bezeichnet. Bevorzugt werden nach dem Einspritzen der ersten Overmoulding-Schicht an darauf folgenden Stationen durch weitere zusätzliche Einspritzeinheiten weitere Schichten erzeugt. Auf diese Weise können Mehrschicht-Kunststoffhohlkörper mit vielen Schichten erstellt werden. Bevorzugt erfolgt dies jeweils durch einen Overmoulding Schritt.Prefers becomes the further thermoplastic material to form an outer skin sprayed onto the hollow plastic body. This process is also referred to as overmoulding. Are preferred after the Inject the first overmolding layer on subsequent Stations through additional additional injection units created additional layers. In this way, multilayer plastic hollow body be created with many layers. This is preferably done in each case through an overmolding step.

Die erfindungsgemäße Spritzblasmaschine mit vier oder mehr Stationen zur Durchführung des oben genannten Verfahrens weist mehrere Einspritzeinheiten und eine Blasstation auf und zeichnet sich erfindungsgemäß dadurch aus, dass mindestens eine Einspritzeinheiten nach der Blasstation angeordnet ist. Vorzugsweise sind zwei Einspritzeinheiten zwei verschiedenen Stationen zugeordnet, zwischen denen eine Blasstation angeordnet ist. Auf diese Weise kann zunächst mit von ersten Einspritzeinheiten eingespritztem Material oder Materialien ein Vorformling gespritzt werden, der in der Blasstation zu dem Hohlkörper ausgeformt wird. Erst darauf wird dann eine weitere Schicht aufgebracht. Auf diese Weise kann ein besonders hochwertiger Kunststoffhohlkörper hergestellt werden.The injection molding machine according to the invention with four or more stations to carry out the above procedure has several injection units and a blowing station and draws According to the invention characterized in that at least one Injection units is arranged after the blowing station. Preferably two injection units are assigned to two different stations, between which a blowing station is arranged. In this way can initially with injected from first injection units Material or materials are sprayed a preform, the is formed in the blowing station to the hollow body. First then another layer is applied to it. In this way can produce a particularly high-quality plastic hollow body become.
