Embodiment Construction

[0041] figure 1A schematic diagram illustrating an apparatus 1 for forming plastic pre-forms into plastic containers according to the invention is shown. Reference numeral 2 here identifies, in very schematic form, a transport unit, such as a blow molding wheel, on which the individual molding stations 4 are provided. Reference numeral 12 identifies a blow mold part, for example a blow mold carrier, the pivot of which can be located here on the reference axis of the drawing for opening and closing the blow mold. The telescopic rod 5 held on the carrier frame 58 can be used to stretch the plastic pre-forms (inside the forming station 4 ) in the longitudinal direction. In addition, nozzles 7 are provided for applying a gaseous medium, in particular pressurized air, to the plastic pre-forms.

[0042] Reference numeral 20 designates a clean room in which the forming station (and one or more further forming stations not shown) is guided. The reference numeral 16 identifies a dri...

Abstract

An apparatus (1) is provided for moulding plastic preforms into plastic containers, including a transport unit (2), on which a plurality of moulding stations (4) is provided and which moves the moulding stations along a predefined transport path (P), wherein the moulding stations (4) respectively have blow mould parts (12) that are movable relative to each other, the parts are movable relative to each other for opening and closing blow moulds; and including a clean room (20) that surrounds the transport path (P), along which the moulding stations (4) are transported, and which is separated from an environment (U) by at least one wall (2); wherein the apparatus includes a cooling system (6) for cooling at least one element of the respective moulding stations (4); and wherein the apparatus (1) includes a supply unit (8) that supplies a gaseous medium to the clean room (20). According to the invention, the apparatus (1) also includes a drying unit (14) for drying the gaseous medium supplied to the clean room via the supply unit (8).

Description

technical field [0001] The invention relates to an apparatus and a method for forming plastic preforms into plastic containers. Such devices and methods have been known for a long time in the prior art. Background technique [0002] The process of bottling certain beverages needs to be performed in an aseptic manner. However, blow molding machines have recently been found to also allow the blow molding process to be carried out under aseptic conditions. These machines thus usually have a clean room in which the molding of the plastic pre-forms takes place. [0003] In order to provide clean room air in such a clean room or the respective isolator, the ambient air is usually filtered, for example by means of a depth filter. This is therefore carried out either centrally by means of a filter device for the entire clean room or in a decentralized manner by means of individual filter units in the isolators or in the individual regions of the respective clean room. In a furth...
