Definitions

  • the invention relates to a method for manufacturing and filling of so-called tubular bags under aseptic conditions and relates in particular to pre-sterilization such a tubular bag packaging machine, according to which Pre-sterilizing the machine then also while maintaining the aseptic system continues to operate in normal operation.
  • At least one longitudinally sealed tube strand is formed from a packaging material web that is conveyed in time by a supply roll and passes through a sterilization station.
  • a tubing string is then cross-sealed below a molding and filling station and from a filling container, the filling material is filled into the bottom end of the tube through a molding and filling tube belonging to the machine, pulled off by one pack length and cross-sealed again to form a closed one to form and fill the bag pack, which is then cut off from the next strand etc.
  • the conveying of the packaging material web drawn off from a supply roll takes place within a sterile space which is also under pressure from sterile air and is also pre-sterilized.
  • This type of tubular bag production and filling under sterile conditions is known, for example, according to German patent application DE 199 10 485 A1 and requires pre-sterilization of both the sterile room, the filling material dispenser and the shaping and filling station located in the end area of the sterile room before starting the clocked continuous operation one or more shaped and filling pipes.
  • this pre-sterilization also includes the packaging material tube which has been formed into a tube by longitudinal sealing and is cross-locked and thus removable by means of cross-sealing jaws arranged outside the sterile space.
  • the objects of the first two publications are additionally equipped with special means, such as adjustable double valves, especially removable caps, in order to be able to apply sterilizing agents to the inside and outside of the tubes, whereby only the surface of the packaging material is limited with regard to the packaging material to sterilize.
  • the packaging material which initially runs through a sterilization bath, passes through two separate sterile chambers in order to be steam-dried in the first chamber and filled in the second chamber after cross-sealing, either inside or outside .
  • the packaging machine according to the aforementioned DE-A-199 10 458 A1 also works with such double tubes, that is to say concentrically arranged in the shaped tube, in one embodiment of which, in addition, the double tube has to be pulled out of the tube already formed for the purpose of pre-sterilization.
  • DE-A-199 10 485 A1 is based on this, since its principle, namely the removal of the packaging material web from a supply roll, passage of a packaging material web sterilization station with a connected single sterile chamber, in the end region of which the molding and filling station is included, is entirely appropriate has proven.
  • the tube formed on the molded tube by longitudinal sealing is pulled off with the cross-sealing jaws, but these have not yet been heated or have not yet reached a sealing temperature, which has the consequence that no cross sealing occurs, i.e. the hose remains open after the cross sealing jaws have been reset and it is not held tightly against the molded tube, which is a prerequisite for the sterile-vapor mixture (e.g. steam as a carrier for hydrogen peroxide) being fed into the gap Enter between the packaging material and the molded tube, flow through it and simply flow out downwards, precisely because the hose is open at the bottom.
  • the sterile-vapor mixture e.g. steam as a carrier for hydrogen peroxide
  • the cross sealing and pulling jaws of the machine can be provided with a cutting device on the outlet opening side, which, however, and should be pointed out, has nothing to do with the cutting elements, which are usually in the center the entire width of the bag is available in the cross sealing jaws in order to be able to separate a completely filled bag from the next strand in time.
  • this is a single-lane machine tubular bag packaging machine shown as before from a holder for a packaging material roll 1 a sterilization station to be passed by the packaging material web PB 2, from a molding and filling station 4 with a Shaped shoulder 4 "equipped shaped tube 4 ', from a filler 5 and from a sterile housing enclosing the sterile room 6 6 '.
  • 7 denotes a filter 7 'and blower 7 "equipped sterile air generator, with 8 Longitudinal sealing jaws, with 9 below the hose opening 10 am Sterile housing 6 'arranged cross sealing jaws and with 11 one Special nozzle for injecting the steam-sterilizing agent mixture into the sterile room 6.
  • This nozzle 11 has supply lines 24 and 25 through which the sterilant and steam fed and mixed in the nozzle 11.
  • the dosing device is kept sterile under sterile air 5 via a four-way valve 12 with a sterile air connection 23 connected, steam also via the valve 12 depending on the position through line 20 and the filling material through line 22 in the dosing device 5 provided with inlet and outlet valves 13, 13 ' reach.
  • This doser 5 and the valves 12 and 13, 13 'shown are known elements, so that they do not require any special description.
  • the also known cross-sealing jaws 9 are, as usual, provided with cross-cutting knives 9 ', with which the filled and closed bags are cut off from the subsequent strand in continuous or normal operation, that is to say after the pre-sterilization that is of interest here only.
  • Existing transverse sealing seam 30 located and below the molded tube end 29 of the hose 3 for the purpose of opening it can be cut off.
  • the tube 3 formed from the packaging material web PB is formed with a slight oversize in relation to the outside diameter of the molding tube 4' , This is done simply by correspondingly different dimensioning and shaping of the shaped shoulder 4 ′′ to the slightly smaller diameter shaped pipe 4 ′, as illustrated in FIG. 5.
  • the annular gap S formed between the hose and the shaped pipe 4 ′ is because the hose 3 is between the shaped shoulder and The longitudinal sealing jaw 8 is still open, and is therefore accessible to the injected steam / sterilizing agent mixture at 15, which according to the invention can simply flow out through the open or open hose 3 at the bottom.
  • a collector 14 which detects the pipe end and the open hose end there, on the one hand connection 16 for the cleaning phase (CIP) and connection 17 for the steam sterilization phase. After cleaning and steam sterilization of the dosing device 5, this collector 14 is simply removed.
  • FIGS. 2 to 4 show sections through different shaped tube arrangements on tubular bag machines.
  • 2 is a machine with only one molded tube 4 ', on which a tube 3 is formed from a correspondingly wide packaging material web, and in the example according to FIG. 3, so-called three-edge sealed bags are produced on parallel molded tubes 4', whereby on two tubes 4 ', two tubes 3 initially connected in the longitudinal direction result from a correspondingly wide packaging material web. These two tubes 3 can then be separated from one another in the longitudinal direction before they are separated into individual bags.
  • FIG. 1 In the exemplary embodiment according to FIG.
  • the so-called CIP cleaning of the dosing unit 5 takes place corresponding position of the valve 12 by means of a Line 22 fed cleaning liquid and then the Sterilization (using saturated steam at approx. 120 ° C) of the dose 5 with appropriate position of the valve 12, the steam is fed through line 20, the valve 13 and the Doseur 5 and the valve 13 'passes and through line 21 also flows through the shaped tube 4 'and also the line 22' is derived becomes.
  • the valve 12 is switched over to supply sterile air through the line 23, with the result that the dosing device 5 and all the valves and lines involved are under sterile air and prevent the ingress of germs from the outside.
  • the supply of sterile air immediately after the cleaning and sterilization phase of the dosing device 5 has the advantage that the molded tube 4 ', which has become more or less hot due to the vaporization, is cooled more quickly with due regard to the packaging material web to be subsequently molded.
  • the sterile air supply to the sterile room 6 from the sterile air generator 7 also takes place at the latest at the end of this phase, ie this sterile air supply is maintained during the following steps.
  • the packaging material web PB is pulled in by hand from the supply roll 1 through the sterile space 6, which is partly necessary for the drawing in of the web by opening access openings 27, with the formation of the tube shape or application of the packaging material web to the molding tube 4 'to below the forming station, that is, up to the lower end of the molded tube 4 '.
  • the access openings 27 (only indicated by dashed lines in FIG. 1) are now closed on the sterile housing 6 ', which thus comes under slight sterile air overpressure.
  • Sterilizing agent and steam are now supplied to the mixing nozzle 11 through the lines 24, 25 and injected as a mixture into the sterile space 6, in the sterile space 6 which is closed to this extent but remains slightly open at the hose opening 10 and a packaging material access 10 ', and is injected as a mixture into the sterile space 6, this mixture also at 15 flows into the annular gap S between the tube 3 and the molded tube 4 'and can flow out of the gap S at the bottom of the tube which is open at the bottom.
  • the sterile air supplied by the sterile air generator 7 and through the line 23 is advantageously introduced at elevated temperature for drying, for which purpose a heating element designated 26 is arranged in the sterile air generator 7.
  • the sterile air supply to the dosing device 5 is switched off via the valve 12, but other sterile air parts supplied by the sterile air generator 7 are maintained at a reduced temperature to the sterile room 6 from FIG. 7.
  • the valve 12 is switched over, the supply of filling material to the dosing device 5 is opened at the same time, and the aseptic normal operation begins, in which the hose end formed by the transverse seal and drawn off by the bag length is filled by the dosing device 5 via line 21.
