Problems solved by technology

[0005] However, recycling the medium used for air impingement of the plastic pre-forms is risky, as impurities, for example, can be carried over by the medium from the pre-forms and thus possibly contaminate multiple blow moulds
This is especially crucial for blow molding machines with high hygiene standards, where microbiological impurities are especially dangerous, because harmful microorganisms that form germs can in this way penetrate into the large number of plastic bottles and thus enter these molded parts. Products filled in plastic containers

Embodiment Construction

[0102] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0103] figure 1 is a schematic diagram of a prior art system for producing plastic containers. The system 50 has a heating device 30 in which the plastic pre-forms 10 are heated. At this point, the plastics material pre-forms 10 are conveyed past the heating device 30 by means of a conveying device 34 , here an endless chain, and heated by a plurality of heating elements 31 . The heating device 30 is followed by a transfer unit 36 ​​which transfers the plastics material pre-forms 10 to a sterilization device 32 . In this case, the sterilizing device 32 also has a transfer wheel 37 , on which a plurality of sterilizing elements can be arranged or can even be arranged in a fixed manner. In this area, for example, hydrogen peroxide gas can be used, or, as mentioned above, sterilization c...

Abstract

The invention discloses a device (401) for cleaning gas in blowing machines for shaping plastics material pre-forms to form plastics material containers. According to the invention at least one gas-processing device (416), which is capable of filtering the gas in a sterile manner and / or of reducing a quantity of an oxidative disinfecting / sterilizing agent contained in the gas flowing through and / or flowing past, is arranged in at least one gas line (402, 402a, 402b) which is a gas supply line (402a) or a gas removal line (402a) of a blowing station (8). The device for cleaning gas can filter gases in a manner of asepsis and / or can reduce the mass of oxidized disinfectant and / or bactericide contained in the flowing gases.

Description

technical field [0001] The present invention relates to an apparatus and method for cleaning gases in a blow molding machine for forming plastic preforms into plastic containers. Background technique [0002] Blow molding machines for forming plastic preforms into plastic containers are already known in the prior art. Usually this type of equipment has a plurality of blow moulds, each of which forms a cavity in which the plastic preform can form a container, in which the preform made of plastic is made The molded part (plastic preform) expands to form a plastic container. In order to expand the plastics material pre-forms, the device has a pressure booster which blows the plastics material pre-forms with air by means of a medium, for example compressed air. Thus, the plastic pre-form is stretched both radially and axially and bears against an inner wall of the blow mold adjoining the cavity. To support the stretching of the plastic container in the axial direction, the bl...
