METHOD AND APPARATUS FOR FORMING PLASTIC PREFORMS INTO PLASTIC CONTAINERS WITH PRE-HEATING OF BLOW MOULDS
Method for operating an apparatus for forming plastic preforms into plastic containers, wherein in a working mode a plurality of forming stations are moved along a predetermined transport path by a movable carrier, wherein these forming stations in each case having blow mould arrangements which in a closed state in each case form cavities, within which the plastic preforms are formed into the plastic containers and the plastic preforms are supplied to these forming stations in order to be formed by supplying a flowable medium to the plastic containers, wherein this forming takes place at least temporarily during the transport of the forming stations along the transport path, and wherein at least temporarily at least components of the blow moulding arrangement are tempered. At least parts of the blow mould are pre-heated in a standstill of the carrier or a movement of the carrier, which is slower with respect to a movement of the carrier in the working mode.
Heating apparatus and heating method for preforms, aseptic blow molding machine and aseptic blow molding method
A heating apparatus and heating method for preforms that heat a sterilized preform to a temperature at which the preform can be molded into a bottle in an aseptic atmosphere. Additionally, an aseptic blow molding machine and an aseptic blow molding method that can mold the sterilized preform into a bottle in the aseptic atmosphere, and can take out the bottle from a bottle molding machine in a state where the sterility of the bottle is maintained. A chamber covering a heating unit that heats the preform is provided, and a sterilizing apparatus that sterilizes the inside of the chamber, and an aseptic air supplying apparatus for maintaining the sterility are provided. Additionally, a chamber covering a molding unit that molds the preform into a bottle is provided, a sterilizing apparatus that sterilizes the inside of the chamber, and an aseptic air supplying apparatus for maintaining the sterility are provided.
Method and device for blow-molding containers which are sterile at least in some areas
A method and a device for producing blow-molded containers, which are sterile at least in some areas, in a blow-molding machine. A preform made of a thermoplastic material is first heated, then stretched by a stretching rod in a blowing station, and then supplied with a pressurized fluid via a blow nozzle, wherein a sterilization device is arranged in the blowing station. The sterilization device has at least one radiation source which emits a sterilizing radiation onto the stretching rod and/or onto the blow nozzle.
Maintenance method for an installation for forming containers, including a resynchronizing procedure
Disclosed is a maintenance method for an installation for production of containers from blanks made of plastic material, which includes: a blow-molding machine including a rotating carousel and a plurality of forming stations, each including a mold; a primary power unit connected to the carousel; a transfer device suitable for inserting a blank into a mold or for withdrawing a container therefrom; and a secondary power unit connected to the transfer device. The method includes the detection of a misalignment of the transfer device with the carousel, and, therefore, operations for desynchronization of the power units, for realigning and then for resynchronization of the transfer device and of the carousel.
BLOW-MOLDING MACHINE AND METHOD OF STERILIZING THE SAME
To simply sterilize a blow-molding machine. A mist or gas of hydrogen peroxide or a mixture thereof is introduced through a valve block disposed adjacent to a molding die, thereby sterilizing at least the molding die and an extension rod that extends into the molding die through the valve block.
