Definitions

  • the present invention relates to an apparatus and a method for rinsing plastic containers.
  • Various processes are known in the beverage-producing industry which serve to clean and in particular to rinse plastic containers.
  • plastic such as PET bottles, plastic films or plastic closures have the peculiarity that they charge electrostatically by friction.
  • dust particles as well as, for example, styrofoam or cardboard residues are attracted to the bottles, plastic closures, etc. and stick to them. These particles can not be removed even by gently shaking and / or blowing off with untreated air.
  • the container transport system has a first station which introduces ionized gas into the containers and a second station which removes contaminants from the containers.
  • the ionized air is only generated in the nozzles themselves.
  • the EP 0 895 816 A1 describes an apparatus for treating or cleaning tubular bodies.
  • a central Heilionmaschinesaku is provided, which promotes ionized air via a line to a plurality of nozzles. More specifically, plastic preforms are treated by this device.
  • the raw preforms are blown with an open and a closed end by means of ionized air, wherein the ionized air is passed in the vicinity of the closed end in the interior of the preforms to achieve in this way a favorable flushing effect.
  • the incoming air flows through the ionization and this has at its center a tapered metal needle and an outer ring, which is placed on the ground of the machine.
  • the air is now due to the high voltage, which may for example be between 3 and 4 kV and is generated here by a transformer, ionized.
  • the conductivity of the air is increased.
  • PET bottles are used because of their manufacturing process, i. a blowing process of PET bottles and also the transport such as an air transporter charged electrostatically. This charge is due to the conductivity, which is generated by the ionization of the air from.
  • the present invention is therefore based on the object to provide an apparatus and a method available which simplify such cleaning or ionization of the containers. This is inventively by the subjects of the independent Claims reached. Advantageous embodiments and further developments are the subject of the dependent claims.
  • the device has an ionization unit, which is arranged between the reservoir and the injection devices, and which ionizes the gaseous medium reaching the injection devices centrally.
  • a reservoir means any device in which said air can be stored.
  • this reservoir may be a compressor that provides pressurized gaseous medium.
  • a central ionizing unit is provided, which supplies the individual movable nozzles.
  • the transport device is a transport wheel.
  • the movement of the Eindüs sharken is at least partially, and particularly preferably coupled during the entire rinsing process to the movement of the containers.
  • the Eindüs are also movably arranged along the transport path of the containers.
  • the Eindüs respondeden on the transport device, which also transports the containers to be mounted or arranged.
  • the injection device it would also be possible for the injection device to move at a different speed and / or in a different direction than the containers.
  • an air generated by a compressor (which is preferably dry and oil-free) can be supplied to the rinser via an optional sterile air filter.
  • This feed can advantageously be supplied via a valve node, which particularly preferably contains shut-off devices and sensors, to a media rotary distributor and to a media channel.
  • the valve node and the mentioned rotary distributor can preferably be the ionization unit, which preferably ionizes the air continuously (inline). Subsequently, the air (e.g., via the staple carrier) can reach the treatment nozzles.
  • the Eindüs recognizeden relative to the containers in the longitudinal direction of the containers are movable and can thus be introduced into this. It would be possible that the Eindüs noticeden be moved in the longitudinal direction of the containers, but it would also be possible that the containers are moved in their longitudinal direction. This movement can be achieved, for example, via a stationarily arranged guide curve, but it would also be possible for the individual ionization units to be moved via servo drives or other electromotive, hydraulic or pneumatic drives.
  • the ionization unit is stationary.
  • the ionization unit is preferably arranged stationary or standing and the Eindüs Anlagenen move towards her.
  • the device has a distribution unit and in particular a rotary distributor in order to distribute the gaseous medium from the ionization unit to the injection devices.
  • the Eindüs sharken are arranged on a rotatable support.
  • a first valve device is arranged in a connecting line between the reservoir and the ionizing unit.
  • the containers are flushed both with liquids and with ionized air, since no contact between the liquid and the Ionisiertechnik occurs.
  • the rinsing unit or rinser can therefore be cleaned on the outside and inside with liquids (wet). This cleaning is advantageously realized by bypassing the Ionisiertechnik if the above-mentioned first valve device is provided.
  • a second valve device is arranged in a connecting line between the ionizing unit and the Eindüs beautyen.
  • the device has a connection line which connects the reservoir to the injection devices while bypassing the ionization unit.
  • This connecting line is used in particular for cleaning the individual components of the device, bypassing the Ionisiertechnik.
  • the connecting line has a first branch and a second branch, which in each case can be brought into fluid communication with the ionizing unit, and the connecting line between these branches preferably has a further valve device. If this further valve device is blocked and the above-mentioned valve devices are opened, a medium, in particular air, passes exclusively from the reservoir to the individual injection devices via the ionization unit.
  • the device has at least one heating device which heats the gaseous medium.
  • this heating device is connected in series with the ionizing unit, so that the air passes either first through the heating unit and then through the ionizing unit or first through the ionizing unit and then through the heating unit.
  • the device has a further rinsing device, which serves for rinsing the plastic containers with a liquid medium.
  • This additional flushing unit can be arranged parallel to the injection with liquid, but it would also be possible that this liquid flushing medium passes through the same Eindüs wornen, through which also the gaseous medium can reach with the ionized air.
  • a supply line for the liquid to be completely separate from the ionization unit so that it is possible in this way to prevent the ionization unit itself from being exposed to liquid.
  • the said flushing nozzles can be arranged stationary or move with the containers with.
  • the device has a suction device to suck a gaseous medium from the containers. It is possible that the suction device opens into the respective Eindüs coupleden. It is also possible that the suction device has a central vacuum source, which sucks the gaseous medium through the individual Eindüs recognizeden or generally from the containers. The vacuum can also be removed via a rotary distributor. The above-mentioned liquid rinsing agent can also be supplied via said rotary distributor.
  • the invention can be realized for several applications. For example, for a Einkanalrinser with an electronic and / or mechanical valve control and preferably a submerged nozzle, if no extraction of the particles is desired. Furthermore, an application for a Zweitkanalrinser with electronic and / or mechanical valve control and preferably also a submerged nozzle is possible if in addition an extraction of the particles is desired with vacuum.
  • plastic containers are understood in addition to plastic bottles or plastic preforms and plastic closures and plastic containers in general. If closures or containers are pre-cleaned prior to disinfecting solution treatment with ionized air, the cleaning effect of the disinfectant solution will increase. Due to the reduced adhesion of particles, the particles and thus possibly also below these particles hidden microorganisms can be removed. In this way, the contact ratio of the disinfecting medium to the carrier, which may be, for example, a container or closure, is improved.
  • the rinsing effect is improved, thereby enabling and improving the contact between the carrier and the disinfecting solution. It would also be possible to treat with the device according to the invention packaging films such as shrink wrap or the like.
  • the present invention is further directed to a method for rinsing plastic containers, wherein the plastic containers are transported by means of a transport device along a predetermined transport path and at least partially during this transport by means of a plurality of Eindüs foundeden be acted upon with a gaseous medium on its inner wall.
  • the injection devices are at least temporarily - in particular along the transport path and preferably also in the direction of movement of the containers - moved and supplied by a common reservoir with the gaseous medium.
  • the gaseous medium reaching the injection devices is ionized by a centrally ionizing unit.
  • a central, in particular stationarily arranged ionizing unit which supplies the individual injection devices.
