Definitions

  • the invention relates to a process for the production and filling of so-called tubular bags under aseptic conditions and relates in particular to the pre-sterilization of such a tubular bag packaging machine, after which pre-sterilization the machine is then also continued to operate while maintaining the aseptic function 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 hose strand is then cross-sealed below a molding and filling station and from a filling container a filling and filling tube belonging to the machine is used to fill the filling material into the bottom end of the tube, to be pulled off by one pack length and to be cross-sealed again to form a closed one and to form filled pouches, which are 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, from German patent application DE 199 10 485 AI and requires pre-sterilization of both the sterile room, the filling material dispenser and the molding and filling station located in the end area of the sterile room before the start of the clocked continuous operation. which consists of one or more shaped and filling pipes.
  • this pre-sterilization also includes the packaging material tube which is 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 packaging material tube which is 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.
  • Such double pipes are referred to, for example, European patent application EP-A-0 232 943, German patent application DE-A-195 10 555 AI and also US patent US-A-4, 537, 007.
  • the subject matter of the first two Publications are additionally equipped with special means, such as adjustable double valves, specially removable caps, in order to be able to apply sterilizing agents to the inside and outside of the tubes. of the packaging material is limited to sterilizing only the surface of the packaging material on the product side.
  • special means such as adjustable double valves, specially removable caps
  • 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 to be dried in the second chamber outside cross seal to be filled.
  • the packaging machine according to the aforementioned DE-A-199 10 458 AI also works with such double tubes, that is to say concentrically arranged in the shaped tube, in the case of one embodiment of which the double tube must be pulled out of the already formed tube for the purpose of pre-sterilization.
  • DE-A-199 10 485 AI is used here because its principle, namely the removal of the packaging material web from a supply roll, passage of a packaging material web sterilization station with an attached single sterile chamber, in the end region of which the molding and filling station is included, is in this respect entirely has proven.
  • the invention is based on the object or is an object of the invention to simplify the necessary pre-sterilization process for such packaging or tubular bag machines and thus also the tubular bag machine itself, in particular to the effect that only one tube per bag string, ie one tube that serves as a valve tube and a filling tube, both valve-free and stationary.
  • the sterile air supply to the dosing device is switched off but maintained to the sterile room and
  • the packaging material tube it is very important and decisive here to specifically keep the packaging material tube open or open behind the outlet from the sterile room and to supply sterile air permanently, with regard to the alternative indication "keeping open or opening” it should be noted that on the one hand this equips the machine with a new supply roll is taken into account and on the other hand the case of a malfunction of the continuous operation of the machine, the latter being the case. the tube with a cross seal hangs under the outlet from the sterile chamber.
  • the hose formed on the molded tube by longitudinal sealing becomes pulled off with the cross sealing jaws, but which are not yet heated or have no sealing temperature, which means that no cross sealing occurs, i.e. the tube remains open after resetting the cross sealing jaws and it is also not held tightly against the molded tube, which
  • the sterile-steam mixture supplied for example steam as a carrier for hydrogen peroxide
  • the gap between the packaging material and the molded tube flow through it and can simply flow out downwards, precisely because the hose is open at the bottom.
  • the cross-sealing and pull-off jaws of the machine can be provided with a cutting device on the outlet opening side for this cutting, but this, and it should be pointed out, has nothing to do with the cutting elements, which are generally in the center the entire width of the bag is available in the cross sealing jaws in order to be able to separate a fully filled bag from the next strand in time.
  • Packing machine of the type mentioned for tubular bags are basically no changes required for carrying out the method apart from corresponding control options, but it is advantageous that only one tube is sufficient for the shaping of the tube and the filling material supply, as is the case with non-aseptically operating tubular bag machines se is the case.
  • tubular bag machines which have several molded tubes in a row and with which packaging material webs cut into correspondingly narrow strips are processed.
  • tubular bag machines which have several molded tubes in a row and with which packaging material webs cut into correspondingly narrow strips are processed.
  • machines for the production of so-called three-edge sealed bags whereby a correspondingly wide packaging material web is placed around two relatively closely adjacent tubes and the longitudinal seam between the tubes is applied to the longitudinal edges of the web and the web.
  • Fig.l shows in side view and in section a tubular bag packaging machine with its accessories for supplying the equipment and the contents;
  • Fig. 2-4 show cross sections through different shaped tube arrangements with the packaging tubes and formed in each case
  • the molded tube which also serves as a filling tube, is enlarged with its molded shoulder.
  • the tubular bag packaging machine shown here as a single-lane machine still consists of a holder for a packaging material web supply roll 1, a sterilization station 2 to be passed by the packaging material web PB, a molding and filling station 4 with a with a shoulder 4 " equipped molded tube 4 ', from a filling material dispenser 5 and from a sterile housing 6 1 enclosing the sterile space 6.
  • 7 denotes a sterile air generator equipped with filters 7' and blowers 7 ", with 8 longitudinal sealing jaws, with 9 below the hose opening 10 on the sterile housing 6 'arranged cross sealing jaws and with 11 a special nozzle for injecting the steam-sterilizing agent mixture into the sterile room 6.
  • This nozzle 11 is provided with feed lines 24 and 25 through which the sterilizing agent and steam are supplied and mixed in the nozzle 11.
  • the dosing device 5 is connected to a sterile air connection 23 via a four-way valve 12 via a four-way valve 12, steam depending on the position, depending on the position 20 and the contents pass through line 22 into the dosing device 5 provided with inlet and outlet valves 13, 13 '.
  • 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 following strand in continuous or normal operation, that is to say after the pre-sterilization which is of interest here only.
  • a schematically indicated in FIG. About the cross sealing jaws 9 to be arranged further cutting device 28, with which, controlled accordingly, the one above a.
  • 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, with a connection 16 for the connection 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.
  • CIP connection Cleaning phase
  • FIGS. 2 to 4 show sections through different shaped tube arrangements on tubular bag machines.
  • FIG. 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.
  • the so-called CIP cleaning of the canister 5 takes place with a corresponding position of the valve 12 by means of a cleaning liquid supplied through the line 22 and then the sterilization (by means of saturated steam of approx. 120 ° C) of the canister 5 with the corresponding position of the valve 12, the Steam is supplied through line 20, passes through valve 13 and dosing device 5 and valve 13 'and also flows through line 21 through shaped pipe' and line 22 'is also discharged.
  • 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 concerned 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 sometimes necessary to be kept open for the drawing in of the web, while forming the tube shape or applying the packaging material web to the molding tube 4 'to below the forming station, that is to say lower end of the molded tube 4 '.
  • the access openings 27 are closed on the sterile housing 6 ', which thus comes under slight sterile air pressure.
  • 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 into the sterile space 6 which is closed to this extent but remains slightly open at 10 and 10 ', and this mixture is also injected into the sterile space 6 at 15 flows between hose 3 and molded tube 4 'and can flow out of the gap S at the bottom of the hose which is open at the bottom.
