Definitions

  • the invention relates to a method and a device for treating containers made of plastic.
  • Plastic containers are used, for example, as beverage packaging.
  • the containers are produced as plastic bottles by blow molding of preforms. This manufacturing process often takes place before filling with the contents in a contiguous system.
  • the preforms supplied as bulk material are introduced into a blow molding machine, heated in a controlled manner and blow-molded at high power in a downstream blowing station.
  • the z. B. are configured with a plurality of rotating blow molds to achieve high production rates.
  • the molded containers are fed to the other parts of the system, for example a rinser or filler.
  • the individual plant components are matched with their production capacities, so that, for example, the blow molding machine can provide enough containers to be able to supply the filling machine continuously with the containers to be filled, even at maximum capacity.
  • Air transport systems are frequently used to transport the empty plastic containers.
  • the plastic containers made of preforms in the described method have in their neck region on a circumferential annular collar, which is always independent of the size of the container in the same place, and in addition, regardless of the type of the respective container always has the same shape.
  • the containers are moved with this collar in a channel in the gill-like or obliquely arranged air nozzles blow sterile air under the collar and so can move the containers with very little friction forward.
  • the entire air transport system may be formed as a closed channel, which has the additional advantage that contamination of the interior of the container is prevented.
  • such transport systems are substantially independent of the container size, since, as stated, even different types of containers regardless of their size in the head area are the same design and thus can be moved in the same transport systems.
  • the air transport systems are very long, depending on the size of the system, in order to be used as a buffer line and the like. They pick up a large number of plastic containers at the same time.
  • the object of the invention is to treat the containers in such a way that they can be transported less susceptible to interference by the interactions of the containers with each other are reduced.
  • the invention achieves this by a method having the features of claim 1 and a device having the features of claim 8.
  • Another advantage of the invention is that the treatment plant can be designed so that the interior of the container is not treated, so that contamination with the treatment medium is prevented, which is particularly useful in the food sector.
  • the containers are externally sprayed with a friction reducing agent.
  • a mixture of a carrier and an active ingredient can be used, for example, by using water as the carrier and, for example, an agent as an effective ingredient for reducing the surface tension or a means for changing the conductivity, a detergent, silicone or even Teflon.
  • the containers are expediently dried, for which purpose the residual heat of the containers, which they still have due to blow molding, is used in an embodiment.
  • the exhaust air from the air transport system can be used if it is deflected in a suitable manner.
  • a drying device for example by infrared radiation or a hot air stream, may also be expedient.
  • the carrier dries off and only the active ingredient remains on the container surface where it reduces the friction of the containers with each other. Any electrostatic charges on the container which are still present due to the blow molding are likewise reduced or completely removed by the treatment, so that an interaction of the containers with one another is thereby likewise prevented.
  • Fig. 1 is a block diagram of a plant with the invention and in
  • Fig. 2 is a schematic side view of a device according to the invention.
  • FIG. 1 A schematic representation of the treatment device according to the invention generally designated 1 is shown in more detail in FIG.
  • Finished preforms 2 are introduced into the system on the input side and first pass through a heating station 3 in which the preforms 2 are preheated to a controlled temperature. Then they run into a blowing station 4, in which they are made by stretch blow molding in the desired container shape, z. B. a bottle for drinks.
  • the molded containers are introduced into the spray station 5 according to the invention and subsequently in the Drying station 6 dried. Then they are by means of an air transport system 7, which also serves as a buffer line, a rinser 8 supplied, in which the containers are cleaned from the inside and possibly sterilized. The sterilized containers are then fed via a further air transport system 9 to a filler 10, in which the containers are filled with the desired contents. Alternatively, other system designs are possible.
  • FIG. 1 A finished blow-molded container 11 made of plastic is transported after leaving the blow molding machine by a spray chamber 12.
  • a plurality of atomizing nozzles 13 are arranged, which finely atomize a treatment agent and thus produce a spray mist.
  • the treatment agent may for example consist of a carrier, such as water, the effective ingredients, for example in the form of detergents, silicones or Teflon attached.
  • a carrier such as water
  • the effective ingredients for example in the form of detergents, silicones or Teflon attached.
  • the spray settles on the surface of the container 11.
  • the carrier evaporates after leaving the spray chamber 12.
  • the container 11 dries off and on the surface remains only the active ingredient in the form of, for example, a thin silicone or Teflon coating back.
  • This layer significantly reduces the friction between the containers.
  • the spraying compensates or removes any existing electrostatic surface charges which may have formed on the surface of the container 11 due to the blow molding process so that interactions between two containers 11 are no longer or only greatly reduced due to electrostatic effects occur.
  • Cooling nozzles 17, which are connected to the air supply of the air transport system, support the drying process by additionally drying the surface by blowing with air.
  • a pump device 14 which pumps the treatment agent from a reservoir 15 to the atomizer nozzles 13 and there provides the pressure necessary to produce the spray.
  • Excess treatment medium which does not precipitate on the surface of the bottles 11, condenses on the walls of the spray chamber 12 or is deposited on this, runs down and is fed via an outlet 16 back to the pumping device 14, so that for example a part of Treatment agent circulates in a closed circuit.
  • an independent drying chamber can still be connected in design, which, in addition to the already described drying mechanisms by irradiation with infrared light or an additional hot air flow, supports the drying of the containers 11 and thus the formation of the film from an effective constituent.
  • the container Before, during or after treatment of the container 11 in the spray chamber 12 according to the invention, the container is then transferred to an air transport system 18, in which the container is transported by nozzle or gill-like projections and correspondingly shaped air flows.
  • the containers 11 can butt against one another in the course of the transport, without them becoming wedged on one another. Both when the containers are in abutment and so transported, as well as when they rotate against each other or collide at different speeds, the containers do not wed or jam together, since by the treatment of the invention the surface friction and / or the electrostatic interactions between them Containers are reduced so much that mutual interaction hardly takes place.
  • the invention is not limited to the above embodiment, but can be modified in many ways without departing from the spirit.
  • the treatment agents used, carrier media or active ingredients are widely modified as long as they are suitable to influence the container surface in a suitable manner, in particular to reduce the friction of the container.
  • the structure of the system ie the application of the medium and the subsequent subsequent drying, can be made in many ways, as long as a sufficient amount of the treatment agent is brought to the relevant points of the container surface.
  • the structure of the plant as a whole can also be varied, in particular in particular with regard to the arrangement of the further treatment stations following the treatment device according to the invention.
  • the transport systems are not limited to air transport.
