Sterile blow moulding machine with non-sterile media supply

摘要

An apparatus for the shaping of plastics material pre-forms into plastics material containers, with a plurality of shaping stations which are arranged on a movable carrier, wherein the shaping stations have blow molds which are used for receiving the plastic pre-forms and inside which the plastic pre-forms are shaped into the plastic containers, and wherein the shaping stations have stressing devices which are movable relative to the plastic pre-forms and which act upon the pre-forms arranged in the blow molds with a sterile flowable medium to expand them, with a clean room, inside which the shaping stations are conveyed, wherein this clean room is arranged or demarcated from the environment by means of at least one wall. At least one supply device is provided for supplying a flowable control medium to at least one shaping station), wherein this supply device (60) is sealed off from the clean room.

1. An apparatus for the shaping of plastics material pre-forms into plastics material containers, comprising:
a plurality of shaping stations which are arranged on a movable carrier, the shaping stations each having blow moulds which are used for receiving the plastics material pre-forms and inside which the plastics material pre-forms are capable of being shaped into the plastics material containers, and wherein the shaping stations have in each case, stressing devices which are movable relative to the plastics material pre-forms and which act upon the plastics material pre-forms arranged in the blow moulds with a sterile flowable medium to expand them a clean room, inside which the shaping stations are conveyed, wherein the clean room is arranged or demarcated from the environment by means of at least one wall; a valve arrangement configured for controlling the gaseous sterile medium supplied to the plastics material pre-forms; at least one first supply device configured for supplying a flowable control medium to at least one of said plurality of shaping stations, said at least one first supply device extending at least locally inside the clean room, wherein said at least one first supply device is sealed off from the clean room in such a way that the flowable control medium is also capable of being conveyed as a non-sterile medium to the shaping station; and at least one second supply device connected to said valve arrangement and configured for supplying the non-sterile medium to said valve arrangement to control actuation of said valve arrangement.
