Definitions

  • the invention relates to a device for the sterile filling of containers, in particular before the containers are removed from the form of a blow molding machine used for their manufacture, which has the features of the preamble of claim 1.
  • the inner surface of the ASR housing and the outer surface of the holding block can only be disinfected with the aid of a disinfectant, because the steam to be used for sterilization cannot be introduced into the ASR housing.
  • the invention has for its object to provide a device for sterile filling of containers, which enables fully automatic cleaning and sterilization not only of the mandrels, but also of all those surfaces that are in contact with the space surrounding the mandrel or mandrels. This object is achieved by a device having the features of claim 1.
  • the ASR housing its connections for the supply and discharge of cleaning fluid, steam and sterile air as well as the closure for the opening or openings in the bottom of the ASR housing, its inner walls and the outer walls of the holding block as well as the mandrel or the mandrels are flushed with cleaning fluid, steam and sterile air, in particular also simultaneously with the sterilization of the mandrel or the mandrels.
  • the previously required mandrel hood can be dispensed with and therefore the bottom of the ASR housing no longer has to be removed before the ASR housing is sterilized and then reinstalled. A fully automatic cleaning and sterilization of all surfaces in question is therefore possible without a person having to touch these surfaces.
  • the opening or openings in the bottom of the ASR housing When the opening or openings in the bottom of the ASR housing are closed, it is preferably an inflatable one There is a seal between the outside of the bottom of the ASR housing and the side of the movable closure facing it.
  • the movable closure is advantageously actuated by means of a working cylinder, so that the closure can also be included in the automation.
  • the metering device is arranged inside the ASR housing between the holding block or blocks on the one hand and the mandrel or mandrels on the other.
  • the arrangement of the dosing device inside the ASR housing has the advantage that it is also automatically cleaned and sterilized. Since a detachable connection can be provided, preferably by means of quick-release fasteners, for the bottom of the ASR housing, if access to the metering device is required, for example a metering membrane has to be replaced, the metering device can be moved downwards out of the ASR housing, after its bottom has been removed.
  • the holding block can be guided on the inner wall of the upper cylindrical part, for precise guidance of the thorn is important.
  • the holding block advantageously has, for its guidance at the transition from an upper section to a lower section, an annular material portion projecting radially outward beyond the outer lateral surface of both the upper and the lower section, which guides the block in the manner of a piston.
  • the area of the upper part of the holding block that receives the upper section of the holding block in its highest position ASR housing with at least one inlet and at least one outlet for cleaning liquid Provide steam and sterile air.
  • the ring-shaped material section is located at the lower end of the upper part of the ASR housing when the holding block is completely lowered. Also protrudes into a central longitudinal channel of the holding block, which is closed at its lower end, from above, a column rigidly connected to the upper end of the upper part of the ASR housing, on which the upper section of the holding block is guided so as to be longitudinally displaceable via a ball bearing bush.
  • the holding block drive device preferably has a hydraulic cylinder as the drive element, so that the holding block cannot be inadvertently lowered when the pressure drops.
  • this hydraulic cylinder is assigned a proportional control which enables precise control of the movement of the holding block.
  • the device according to the invention is not only suitable for equipping new machines, but also for retrofitting, especially since it is highly suitable for clean rooms.
  • the latter is also due to the fact that there are only two movable bushings to the interior of the ASR housing and the seals of the bushings slide on walls which limit the evacuable interior of the ASR housing and can be cleaned and sterilized.
  • a device for the sterile filling of containers, in particular a row of ampoules or bottles, before removal from the mold of a blow molding machine used for their manufacture has a cuboid lower part 1 of a filling sterile space housing, hereinafter referred to as ASR housing, on which its underside is tightly closed by means of a base 2.
  • This base 2 is detachably connected to the ASR housing by means of quick-release fasteners 3, which are designed as tension locks.
  • the inner surface of the bottom 2, as shown in FIG. 1, has a slope from the two long sides 1 'of the lower part 1 to the center, where a passage opening 5 is provided for each filling mandrel 4 present. These passage openings 5 serve not only for the passage of the mandrels 4, but also for the discharge of cleaning fluid and steam.
  • the passage openings 5 can be closed tightly by means of a closure slide 6 provided on the underside of the base 2, which can be closed by means of at least one working cylinder 7 between the closed position shown in FIG. 1 and one Release position is displaceable, in which the closure slide 6 is located near a holder 8 provided on the lateral longitudinal edge of the base 2.
  • the slide valve 6 On the top facing the bottom 2, the slide valve 6 is provided with a circumferential, self-contained groove 9 in which there is an inflatable seal, not shown, which is inflated when the slide valve 6 is in the closed position.
  • two identical upper parts 10 are placed near the two narrow sides 1 ′′, which have the shape of a cylindrical pot which is open at the bottom and whose longitudinal axis runs perpendicular to the upper side of the lower part 1.
  • the two upper parts 10 are each aligned with an opening 11 in the upper side and tightly connected to the latter.
  • a holding block 12 is guided in a longitudinally displaceable manner.
  • These two identically designed holding blocks 12 can each be moved in their longitudinal direction by means of a hydraulic cylinder 13 arranged on the outside next to the upper part 10, which corresponds to an up and down movement in the installed state of the device.
  • the holding block 12 has a radially outwardly projecting, annular material section 14, which is guided in the manner of a cylinder from the inner wall of the upper part 10.
  • annular seal lying in a radially outwardly open annular groove 15 of the material section 14 seals the space above the material section 14 from the space below the material section 14, which is in communication with the interior of the lower part 1.
  • annular seal lying in a radially outwardly open annular groove 15 of the material section 14 seals the space above the material section 14 from the space below the material section 14, which is in communication with the interior of the lower part 1.
  • its material section 14 is at the level of the end of the upper part 10 adjoining the lower part 1.
  • the holding blocks 12 are provided with a central blind hole 16 which is closed at the lower end and into which a column 17 rigidly connected to the upper part 10 engages.
  • the upper section 12 ′ of the holding block 12 is guided on this column 17 without play by means of a stainless steel ball bushing 18. This guidance also contributes to achieving high accuracy.
  • the lower end of the column 17 carries a guide piston 19 which carries a sealing ring which bears against the inner wall of the lower section 12 ′′.
  • the two holding blocks 12 carry a block-shaped metering device 20 fixed on their underside, which has connections for the mandrels 4 on their underside facing the bottom 2 of the ASR housing, of which only one in FIG. 2 and not all in FIG. 3 are shown.
  • the metering device 20 contains for each mandrel connection the valves required for time-pressure metering, which in the exemplary embodiment are diaphragm valves.
  • two connecting pieces 21 and 22 are provided, via which cleaning liquid, steam and sterilized air can be introduced into the interior of the ASR housing and can be removed therefrom.
  • the two upper parts 10 of the ASR housing in the area which receives the upper section 12 'of the holding block 12 in its highest position, have an upper connecting piece 23 and a lower connecting piece 24, via which cleaning liquid, steam and sterile air are also supplied and can be derived.
  • tubes 25 running parallel to the columns 17 penetrate the cover 10 ′ which delimits the upper parts 10 upwards and are firm and tight with the associated holding block 12 connected.
  • the tubes 25 therefore move together with the holding blocks 12 relative to the upper part of the ASR housing, which is why a seal is provided in the area where the tubes 25 pass through the cover 10 '.
  • cleaning liquid is now first introduced, which includes all channels of the mandrels 4 and their supply lines as well as all wall surfaces of the ASR housing, the holding blocks 12 and Dosing device 20 cleans which are in contact with the space surrounding the mandrels 4 and can come into contact.
  • the cleaning liquid is drained off via the connecting piece 22 and the lower connecting piece 24. If, as in the exemplary embodiment, the closure slide 6 is provided with a discharge channel 6 ', part of the cleaning liquid can also be discharged via this. After this cleaning, all parts are sterilized with steam, which can have an overpressure of up to 3 bar.
  • the steam can not only be supplied and discharged through the pipes 25, but can also be introduced into the ASR housing through the connecting piece 21 and the upper connecting piece 23. All interior walls of the The ASR housing and all the outer walls of the metering device 20 and the holding blocks 12 are therefore sterilized by means of the steam.
  • This also applies to the area above the material section 14 of the holding blocks 12, the pillars projecting into the ASR housing, the outside of the tubes 25 inserted through the covers 10 'and the actuating rods 26 also inserted through the covers 10' which the hydraulic cylinders 13 move the holding blocks 12. Therefore, all seals in the area of the bushings and the seal of the material section 14 run on a wall surface that can be cleaned and sterilized.
  • the steam is conducted via the exhaust air duct of the mandrels 4, via which the air escapes from the container to be filled during the filling process, via the connecting pieces 22 and 24 and via the discharge duct 6 'to a condensate drain.
  • the cleaning and sterilization can therefore be carried out fully automatically, which gives a much greater certainty that no germs can come into contact with the inner surfaces of the ASR and the parts touching the product to be filled.
  • the operator must exercise extreme caution to avoid contamination of the surfaces and parts mentioned.
  • the dosing device is also included in the non-contact, automatic sterilization, maintenance of the dosing device or, for example, the replacement of a membrane, presents no difficulties. This is because only the bottom 2 together with its slide 6 to be removed, which is easy to do thanks to the quick-release fasteners. The holding blocks 12 are then completely lowered. The metering device 20 emerges from the bottom of the ASR housing and is therefore easily accessible.
