Anmerkung: Text basiert auf automatischer optischer Zeichenerkennung (OCR). Verwenden Sie bitte aus rechtlichen Gründen die PDF-Version.
The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:
1. A device for producing and filling containers, comprising: an extruder; a mold alignable with said extruder and receiving a tube of plasticized plastic material from said extruder; a filling device including several function channels separate from one another and a filling mandrel having a central functional channel delivering filling material out an outlet on an end section of said filling mandrel to a container formed in said mold, said filling mandrel being movable into selected operating positions by longitudinal displacement thereof; and a protective cover being movable into and out of a functional position, having
first functional space and a second functional space offset relative to one another in a direction of the longitudinal displacement of said filling mandrel and having a media carrying connection in the functional position thereof for at least one of cleaning, sterilizing and drying of said filling device and the respective function channels thereof, said filling mandrel interacting with said protective cover with a longitudinal section thereof in at least one of said functional spaces in the functional position of said protective cover, said first functional space receiving said end section of said filling mandrel.
2. A device according to claim 1, wherein said second functional space houses said longitudinal section of said filling mandrel, said longitudinal section being connected to said end section of said filling mandrel, said second functional space having an input opening connecting another function channel of the filling device to said second functional space in an operating position of the filling device and in functional position of the protective cover.
3. A device according to claim 2, wherein said filling mandrel extends through an extruder head of said extruder, said extruder head having a face adjoined flat by a cover wall of said protective cover in the
functional position thereof, said input opening being in said cover wall, said other functional channel extending along an outer side of said filling mandrel, through said extruder head and ending on said face.
4. A device according to claim 1, wherein each of said first and second functional spaces comprises a media outlet discharging respective media supplied by connections to said function channels to an outside environment.
5. A device according to claim 4, wherein said protective cover comprises a protective body having an input opening adjoined by said second functional space, said second functional space being separated from said first functional space by an insert seal, said first functional space following coaxially from said second functional space, said seal insert forming a central passage for entry of said end section of said filling mandrel, said end section being needle-shaped.
6. A device according to claim 5, wherein said protective cover is movable by displacing a cover wall thereof along a face of said extruder into and out of the functional position.
7. A device according to any one of claims 1 to 6, wherein said filling device comprises a dosing system in fluid communication with said
central function channel and comprises supply devices alternatively supplying at least one of filling material, cleaning media, sterilizing media, drying media and cooling media to the respective function channels.
8. A device according to claim 7, wherein at least one of said function channels is located outside said filling mandrel, forms a flow path routed along an outer side of said filling mandrel and is supplied with a sterile, gaseous medium dischargeable on a face of an extruder head of said extruder and into an inside of a tube formed during an extrusion process with the sterile, gaseous medium being support air stabilizing the tube and forming a sterile zone in the tube.
9. A device for producing and filling containers, comprising: an extruder; a mold alignable with said extruder and receiving a tube of plasticized plastic material from said extruder; a filling device including several function channels separate from one another and a filling mandrel delivering filling material to a container formed in said mold; and a protective cover being movable into and out of a functional position, having
first and second functional spaces and having a media carrying connection in the functional position thereof for at least one of cleaning, sterilizing and drying of said filling device and the respective function channels thereof, each of said first and second functional spaces having a media outlet discharging respective media supplied by connections to said function channels to an outside environment, said protective cover including a protective body having an input opening adjoined by said second functional space, said second functional space being separated from said first functional space by an insert seal, said first functional space following coaxially from said second functional space, said seal insert forming a central passage for entry of an end section of said filling mandrel, said end section being needle-shaped.
10. A device according to claim 9, wherein said protective cover is movable by displacing a cover wall thereof along a face of said extruder into and out of the functional position.
11. A device according to claim 9 or 10, wherein said filling device comprises a dosing system in fluid communication with a central one of said function channels and comprises supply devices alternatively supplying at least one of filling material, cleaning media, sterilizing media, drying media and cooling media to the respective function channels.
12. A device according to claim 11, wherein at least one of said function channels is located outside said filling mandrel, forms a flow path routed along an outer side of said filling mandrel and is supplied with a
sterile, gaseous medium dischargeable on a face of an extruder head of said extruder and into an inside of a tube formed during an extrusion process with the sterile, gaseous medium being support air stabilizing the tube and forming a sterile zone in the tube.
13. A device for producing and filling containers, comprising: an extruder; a mold alignable with said extruder and receiving a tube of plasticized plastic material from said extruder; a filling device including several function channels separate from one another and a filling mandrel delivering filling material to a container formed in said mold; and a protective cover movable into and out of a functional position, having a first functional space and having a media carrying connection in the functional position thereof for at least one of cleaning, sterilizing and drying of said filling device and the respective function channels thereof, said filling device including a dosing system in fluid communication with a central one of said function channels and including supply devices alternatively supplying at least one of filling material, cleaning media, sterilizing media, drying media and cooling media to the respective function channels, at least one of said function channels being located outside said filling mandrel, forming a flow path routed along an outer side of said filling mandrel and being supplied with a sterile, gaseous medium dischargeable on a face of an extruder head of said extruder and into an inside of a tube formed during an extrusion process with the sterile, gaseous medium being support air stabilizing the tube and forming a sterile zone in the tube.
