Blow moulding machine with blow mould changing robot with additional treatment function

A system for transforming plastic parisons to plastic containers with a transport device which transports the plastic parisons along a predetermined transport path, wherein the transport device has a movable station support disposed at least indirectly on a stationary base support on which a plurality of transforming stations is disposed, wherein the transforming stations each have blow mould devices which each having cavities within which the plastic parisons can be transformed into plastic containers and the blow mould devices are each disposed on blow mould supports, wherein the system has a changing device which is adapted, in a changing mode of the system, at least to remove the blow mould devices from their blow mould supports and/or to dispose blow mould devices on the blow mould supports, and wherein, during a further mode of operation which differs from the changing mode, the changing device is adapted for carrying out a treatment operation on at least one working element intended for the system, wherein the treatment operation is selected from the group consisting of a cleaning operation, a maintenance operation, a sterilising operation, and a combination thereof, and wherein the changing device has at least one treatment device adapted for treating the working element or a gripping device adapted for gripping the blow mould device wherein the treatment device is replaced by the gripping device or vice versa.
