Embodiment Construction

[0146] Figure 1 is a schematic view of a plant for producing plastic containers according to the prior art. The plant 50 has a heating device 30 in which the plastic parisons 10 are heated. In this case, the plastic parisons 10 are guided through the heating device 30 by means of a conveying device 34 , for example an endless chain in this case, and are heated by heating elements 31 in the process. This heating device 30 adjoins a transfer unit 36 ​​which transfers the parisons 10 to a sterilization device 32 . In this case, the sterilization device 32 also has a transport wheel 37 , and the sterilization elements can be arranged on this transport wheel 37 or can even be fixed. In this area, germs can be sterilized, for example by hydrogen peroxide or even, as mentioned above, by electromagnetic radiation. Specifically, internal sterilization of the parisons is carried out in this area. In the case of electromagnetic radiation, the radiation fingers advantageously protrude ...

Abstract

An apparatus comprises a conveying device and a plurality of blow moulding stations arranged on the conveying device. Each blow moulding station includes a blow mould. A clean room is provided inside which the plastics material pre-forms are conveyed. The blow mould has two lateral parts and a bottom part that jointly form a cavity inside which a plastics material pre-form is shaped into a plastics material container. A drive device moves the lateral parts or the bottom part of the blow mould. A coupling device couples the drive device to a lateral part. A mounting device mounts the coupling device.

Description

technical field [0001] The invention relates to an apparatus for forming plastic parisons. The use of plastic containers, which are produced from plastic preforms by forming processes and in particular by blow molding processes, is known in the field of the beverage production industry. In this case there is usually provided a blow molding wheel on which a plurality of blow molding stations are arranged, the plastic parisons being expanded against the corresponding blow mold by the action of compressed air inside these blow molding stations the inner wall. Such a blowing wheel is preferably designed in the form of a rotor and rotates in a continuous manner about its axis of rotation. In particular, the axis of rotation is oriented vertically. The extension of the axis of rotation thus intersects the center point of the ground. Background technique [0002] For many beverages it is necessary in this case to fill the beverage under aseptic conditions. In this case, the kn...
