Definitions

  • the invention relates to a method according to the preamble of claim 1 and to a system according to claim 12.
  • a method for producing bottles, KEGs or the like containers made of thermoplastic material, in particular PET by blow molding or stretch forming from preheated preforms using compressed air as blowing or process gas are known.
  • the disadvantage here is, inter alia, that during blow-molding, air-oxygen diffuses into the wall of the container, which severely impairs the quality and / or the taste and / or the shelf life of such products, especially in the case of oxygen-sensitive products filled in such containers. It is also disadvantageous that the filling process contained in the containers, often directly following the blow molding process
  • Atmospheric oxygen must be removed by one or more rinses.
  • expensive carbonic acid is used in practice.
  • Oxygen-sensitive products in the context of the invention are products of various kinds and different consistency, which are impaired or damaged by oxygen.
  • Oxygen-free or substantially oxygen-free process gas in the context of the invention is a gas which contains no oxygen (O2, O or O3) or at most only such a small, negligible proportion of oxygen, which does not affect or damage the in the container produced bottled product leads.
  • the oxygen-free or substantially oxygen-free process gas then mainly contains nitrogen, possibly further constituents, such as a small amount of argon or carbon dioxide, and was preferably obtained by fractionation of ambient or atmospheric air.
  • Fractionation of ambient or atmospheric air in the sense of the invention means the separation of the ambient or atmospheric air in their gas and Steam components, in particular by using at least one gas filter, preferably by using at least one membrane filter.
  • the object of the invention is to provide a method and a system, with or in a rational manner a production of containers, such as bottles or KEGs by blowing or stretching without one or at least with a greatly reduced oxygen diffusion into the wall the container is possible. It is also an object of the present invention to at least reduce the rinsing operations preceding the filling. To solve this problem, a method according to claim 1 is formed. An installation for producing containers, for example bottles or KEGs by blow molding or stretch forming, is the subject of patent claim 12.
  • the plant generally designated 1 in the figure is used to produce bottles 2 from a thermoplastic, preferably PET bottles or PET drums by blow molding using preforms or preforms 3 of the thermoplastic material or PET.
  • the plant 1 essentially comprises a preforming task 4, in which the preforms 3 are provided as a disordered quantity and from which they then hang in a predetermined orientation, namely on a conveyor 5 with its flange 3.1 forming the later mouth flange 2.1 of the bottles 2 Heating section 6 for heating to a temperature of, for example, about 135 0 C. be supplied.
  • the plant 1 further comprises a subsequent directly to the heating station 6 blowing machine 7, for example, in a manner known to those skilled in a circulating around a vertical machine axis rotor having a plurality of blow molds in which from the preheated preforms 3 by blowing or stretching the bottles 2 are formed.
  • the finished bottles 2 are then fed from the blow molding machine 7, for example with their mouth flange 2.1 hanging on a conveyor to another use (arrow A).
  • Appendix 1 A particularity of Appendix 1 is that the blowing of the bottles 2 in the blow molding machine 7 using an oxygen-free or substantially oxygen-free process gas, i. a substantially consisting of nitrogen process gas takes place, which in a plant 1 directly associated gas filter 9, i. obtained at the place of manufacture of the bottles 2 by fractionating ambient air, which is supplied to the gas filter 9 via a sterile filter 10 (arrow B).
  • an oxygen-free or substantially oxygen-free process gas i. a substantially consisting of nitrogen process gas takes place, which in a plant 1 directly associated gas filter 9, i. obtained at the place of manufacture of the bottles 2 by fractionating ambient air, which is supplied to the gas filter 9 via a sterile filter 10 (arrow B).
  • At least one filter membrane 11 and / or at least one combination of filter membranes (11) is provided, which is arranged and selected in terms of their filtering effect such that the gas component of the air, namely nitrogen, which retains the process gas, is retained on it the remaining gas components of the ambient air, or at least the oxygen are forwarded, so that at the at least one filter membrane 11 associated output or the local line 12, the oxygen-free or substantially oxygen-free process gas is available and can be fed to a process gas supply 13 of the blow molding machine 7 in which the process gas is stored and / or compressed to the pressure required for blow molding (eg approx. 40 bar).
  • PET bottles are manufactured.
  • the invention is not limited to the production of bottles, but also includes the production of other containers by blow molding or stretch forming, in particular the production of KEGs and especially of PET-KEGs.
  • the preheating the preforms 3 in an oxygen-free or substantially oxygen-free atmosphere ie to carry out in the nitrogen atmosphere, so as to prevent this pre-heating an in-diffusion of air-oxygen in the bottle 2 forming plastic.
