Definitions

  • the invention relates to a method for sterilizing a web of packaging material according to the preamble of claim 1.
  • a method of this type which has become known, for example, from EP-A-142 758
  • the pre-cleaning of the web of packaging material is carried out in a water bath using ultrasound waves. During this cleaning, a part of the germs is detached from the surface of the packaging material and removed, so that there is a reduced germ load during the subsequent UV (ultraviolet) radiation.
  • This known method produces an on average quite good sterilization rate.
  • studies have shown that the packaging material web is not sterile enough. It is therefore desirable to use a chemical-free sterilization process for a web of packaging material, which ensures uniform disinfection with a high sterilization effect.
  • the method according to the invention with the characterizing feature of claim 1 has brought the surprising result that the combination effect of wet cleaning with brushes and subsequent UV irradiation of the packaging material web is considerably better than pre-cleaning with ultrasound. Investigations have shown that wet cleaning with brushes has a worse cleaning effect than ultrasonic bath cleaning.
  • the superior effect of the method according to the invention can only be subsequently explained in such a way that particles which are loosely adhering to the packaging material surface and also microorganisms are released by cavitation when subjected to ultrasound cleaning, but that there is no detachment in the case of strongly adhering accumulations of dust and microorganisms and that microorganisms in such clusters are only imperfectly reached due to the shadow formation by UV light.
  • microorganisms sometimes adhere quite loosely to the surface, since they are first detached by the cleaning and then washed up elsewhere. These microorganisms can be removed by a sharp sterile water jet and also by a sharp sterile air jet, which further improves the sterilization result.
  • a device for performing the method according to the invention has at least one roller-shaped brush upstream of the UV radiation source and brushing the surface of the packaging material web.
  • a very good cleaning result is achieved if the ends of the bristles of the brush brush the surface of the packaging material web with low tension.
  • Such a device has a simple and inexpensive structure and treats the packaging material gently.
  • a packaging material web 1 is continuously drawn off from a supply roll 2 and passed from above into a container 12 via a deflection roll 11. There it is zigzagged over three lower and two upper deflecting rollers 13 to 17 and then out of the container 12 upwards over a certain distance and then via a deflecting roller 18 to a packaging machine (not shown).
  • the container 12 contains a sterile water bath 3, the level of which lies above the upper deflection rollers 16, 17.
  • a roller-shaped brush 21, 22 is rotatably arranged coaxially over the upper deflection rollers 16, 17, the bristles 23 of which protrude radially.
  • the axes of rotation of the brushes 21, 22 have a distance from the upper surface line of the rollers 16, 17, which is about 1 mm smaller than the radius of the bristles 23 of the brushes 21, 22, so that the ends of the bristles 23 over the Spread deflection rollers 16, 17 guided web 1 with low tension.
  • the brushes 21, 22 are driven to rotate in a direction that runs counter to the conveying direction of the web 1.
  • the two brushes 21, 22 are arranged under hoods 25, 26 and dip into the sterile water bath 3 with their lower part, so that they touch the web 1 guided over the rollers 16, 17 with low tension with the bristles 23 projecting downwards.
  • the brushes 21, 22 subject the packaging material web 1 to intensive mechanical cleaning in the presence of water, some of which the particles adhering to the coated surface of the web 1, such as dust, microorganisms or the like, are dissolved.
  • the packaging material web 1 is passed between two nozzles 31, 32 which rinse both sides of the web 1 with sterile water in a wide, sharp jet, whereby loose foreign particles are washed away. Then the web 1 runs again between two nozzles 33, 34 which blow sterile compressed air onto the web 1 on both sides in a sharp jet, so that remaining water residues are peeled off and dried away. Finally, the web 1, with the side previously brushed by the brushes 21, 22, is guided past a UV lamp 35, where it is irradiated with UV light.
  • the UV lamp is preferably of the C type with a power of 110 mW cm2.
  • the irradiation time is preferably 5 seconds. Subsequently, the web 1 treated in this way is fed to a packaging machine, not shown, for forming packaging containers.
  • only one side of the packaging material web 1 is treated, namely the side forming the inside of the packs. It is also possible to sterilize the other side of the packaging material web by an appropriate arrangement of brushes and a UV lamp. It may also be advantageous to add detergents or relaxation agents to the sterile water bath.
