Definitions
- the invention relates to a device for sterilizing Packaging material webs, especially under wet room conditions, which in of an FFS machine can be further processed, whereby the sterilization of at least the surface of the product Packaging material web with a barrier discharge by means of at least a discharge tube through which a fluid medium flows is effected, which is arranged opposite a counter electrode.
- WO 95/09256 a method for cleaning surfaces, in particular films, using a so-called barrier discharge has been proposed, the sterilization or disinfection of packaging material webs also being taken into account.
- This process which is also assumed here, exploits the physical phenomena associated with electrical discharges to the effect of UV light in order to clean the surfaces of grease or oil films, for which this process has also proven to be useful and, in principle, also for sterilization or disinfection purposes of packaging material webs, provided that they are used as packaging for germ-sensitive filling goods, e.g.
- thermoforming machines in particular thermoforming machines, but also so-called flow wrapping machines are to be understood that shape the packaging material webs involved, fill and s onnect, and in thermoforming machines under packs toffbahn also means the additional cover sheet to be fed.
- the invention is accordingly based on the object, since The procedure of parrier unloading itself does not change anything device used so far (is essentially the flow-through discharge tube with guide elements for the foil guide) to improve in particular under wet room conditions and taking safety requirements into account a largely uniform application of the each continuous packaging material area takes place and thus a correspondingly uniform sterilization or disinfection who was immediately transported to the next station under sterile conditions Packaging material web is guaranteed.
- the device consisting of at least one discharge tube one each supporting the packaging material web, opposite the Discharge tube arranged at a short distance, which forms the discharge or counterelectrode, the sensor-controlled with means for keeping the temperature constant provided with a temperature level that is compatible with the packaging material web is, and that in or on the feed line of the fluid medium a sensor-controlled one for each at least one discharge tube Temperature control device for keeping the temperature somewhat is arranged above the dew point temperature.
- the device with a packaging material tensioning device and this in the direction of travel of the packaging material web arranged in front of the at least one discharge tube is.
- a tensioning device e.g. weight lever-loaded Packaging material guide roll or dancer roll
- packaging material guides generally known, but wins in the present context of particular importance to the required exact Keep the gap distance safely.
- Such a tensioning device is suitable for cases in which the wing for the Packaging material is designed in the form of a rotatable cylinder around in a partial area, for example, several discharge tubes are arranged. If the wing is stationary, flat plate, it is from the same Basically provided with suction holes distributed over the entire surface when the packaging material does not obstruct the suction Keep the packaging material close to the wing and therefore for a constant gap distance between the packaging material and the discharge tube to care. Such suction openings can also additionally to the tensioning device on one of the wings Cylinders are provided if this is the material of the packaging material demands.
- thermoforming machine explained as an FFS machine.
- thermoforming machine shown as a thermoforming machine
- tubular bag packaging machines whereby at the latter usually only a packaging material web over a form shoulder guided and connected to a hose on the associated filling tube shaped and filled this intermittently with transverse sealing becomes.
- the device for sterile treatment of the packaging material webs at the latest is assigned to the respective packaging machine where in Direction of flow the filling follows and the packaging material still is not deformed, i.e., the packaging material web is flat the machine is running or is being fed to it.
- deep-drawing machine of the type shown in FIG.
- the device consisting of at least one discharge tube 1 each has a supporting surface 2 which supports the packaging material PB and is arranged at a short distance from the discharge tube 1 and forms the counterelectrode, which is sensor-controlled with Means 3 for keeping the temperature constant is provided at a temperature level which is compatible with the packaging material web, and that in or on the feed line 4 of the fluid medium to the at least one discharge tube 1 in each case a controllable temperature control device 5 (TG ' ) for maintaining the temperature is arranged somewhat above the dew point temperature.
- TG ' controllable temperature control device 5
- the wing 2 is, as mentioned and in 1 shows a rotatable cylinder or a drum, but it can also be a flat surface or one Act table, as shown in Fig. 2. Both drum and table 3 can be tempered with suitable means 3 trained, i.e. the respective wing 2 is sensor-controlled from a temperature control unit TG for each Packaging material kept at a suitable temperature to keep it in the irradiation area the device does not cause deformation of the packaging material let come, i.e., the wing 2, no matter which Form has this, is constantly below in terms of its temperature Kept control.
- a sensor-controlled Temperature control device TG ' is provided, through which the discharge tubes 1 flowing fluid is passed.
- the discharge tube 1 As illustrated schematically, with suitable flow and return connections 8, 9 provided by which also from special Reason for the energy supply lines 10 for the radiation causing Blement 11 is inserted into the discharge tube 1.
- the wing 2 in the form of a table (see Fig. 2) is formed, it is uniform over the entire surface distributed suction holes 7 and a not particularly shown here Provide suction connection, the suction of which is set in this way must be that on the one hand the packaging material in a flat area held on the wing 2, on the other hand the clocked Passage of the packaging material over the wing 2 but not hindered becomes.
- a cylindrical wing can also be used 2 are provided with such suction holes according to FIG. 1.
- connections 1 ' advantageous in the temperature controlled via liquid Flow and return connections 8, 9 integrated. If in Connection area at the ends of the discharge tube hood covers are provided, they are designed so that condensation on the hoods does not accumulate the connections can arrive, or the hoods are even in the Trained in terms of temperature control and control.
- At least on the flow and return connections 8, 9 and the wings 2 moisture sensors 13 are arranged, which also affect the temperature control devices TG, TG 'are switched.
