Definitions

  • the present invention relates to a bottling plant according to the preamble of claim 1.
  • Such a filling system has become known in the form that highly effective powdery or flowable media have had to be packed in a clean room when transferring or packaging, in particular in pharmacy and in chemical process engineering.
  • Media of this type are prepared, for example, in screw mixers, filter arrangements, agitator containers and the like and then have to be filled under hermetically sealed conditions. So far, it has only been known to carry out such a filling in a clean room in order to protect the personnel who operate the filling device from exposure to these dangerous media.
  • a filling device in which the medium to be filled is under Clean room conditions are proportioned and packaged.
  • the outlet opening of the production system opens into a filling opening of a hermetically sealed container, which consists of a bagging system.
  • the sack to be filled is clamped between the edge of the container and a flange extending from the filling opening.
  • the filling system described here avoids contamination of the area outside the clean room during filling, but still requires protective measures for the operating personnel, as have already been described above.
  • the object of the present invention is therefore to develop a filling system of the type mentioned at the outset in such a way that dangerous media can be filled at significantly lower costs and without endangering personnel.
  • the invention is based on the technical Teaching of claim 1 characterized.
  • the filling takes place in a hermetically sealed container, on the top of which there is an inlet opening for the dangerous medium to be packaged, and in the interior of which the actual filling system is arranged.
  • the advantage of this arrangement is that no special protective equipment is required for the operating personnel and that a so-called clean room can also be dispensed with.
  • the container according to the innovation reliably seals off the dangerous media and ensures safe loading and emptying.
  • the container is connected to a vacuum system which, in the event of damage to the tightness of this container, prevents the emission of pollutants in the event of faults.
  • the container can also be easily cleaned from the inside and there are only short interruptions when changing the packaging medium.
  • the media described above can all be pourable and flowable media, but especially z.
  • the intended for the production of the media Manufacturing facility e.g. B. a cone screw mixer, sits directly with its outlet opening at the inlet opening of the container.
  • the dosage of the medium i.e. H. that is, the amount of medium that is to enter the container is preferably accomplished on the manufacturing side. It can be provided that a corresponding ball segment valve is provided on the underside of the cone screw mixer, which allows a certain amount of the medium to flow into an outlet opening, on the underside of which a metering valve is arranged.
  • the said ball segment valve is therefore only used for the hermetic closure of the bottom opening of this conical screw mixer, while the actual metering takes place through the metering valve which is arranged below in the direction of flow of the medium.
  • This metering valve is placed directly on the inlet opening of the container.
  • the packaging and weighing unit is now arranged in the container itself.
  • the barrel container can also be double-walled, namely from a relatively rigid outer wall, the z. B. consists of plastic, paper or metal and an inner safety cover, which represents the inner double wall of this barrel container.
  • the sack is now suspended in this double-walled barrel container and attached with its upper opening to the inflatable sealing part.
  • This sealing part is now inflated and holds the bag sealingly on the underside of the flange which is connected to the inlet opening.
  • the ball segment valve is first opened and then the metering valve is then put into operation in order to allow a certain, measured amount of the dangerous medium to flow into the sack via the now opened inlet opening and the flange.
  • the medium now accumulates in the interior of the sack, which sits in the barrel container, up to a prescribed weight, which is determined by a weighing and lifting system on which the entire barrel container with the sack to be filled sits.
  • the metering valve is first closed, then excess air is sucked out of the interior of the sack through a vent line attached to the flange below the inlet opening.
  • the sack contracts and can be closed, the inflatable sealing part still functioning and keeping the sack hermetically sealed to the underside of the flange.
  • the sack can now be tied off and cut off. The upper part of the sack then sticks to the inflatable seal, while the lower, now tied sack rests in the barrel container.
  • the sack is now inserted into the barrel container by hand through the access openings arranged on the container, in which case it is then surrounded by the safety cover.
  • This safety cover is intended to prevent the medium from trickling downwards when the sack is removed.
  • the container is still under negative pressure and the loading opening on the side wall of the container is opened and the barrel container with the filled sack contained therein can be removed from the container.
  • a new container is then placed on the weighing and lifting system, which carries a sack to be filled.
  • the loading opening is closed and the safety lid is pivoted away from the opening in the container, so that when the barrel container is lifted it protrudes through an opening in the container.
  • the new bag to be filled is now connected to the blow-out sealing part by hand and this is inflated.
  • the new sack is now ready to be filled. A new filling process then takes place, as described above.
  • the entire filling of the medium takes place under clean room conditions and under the greatest protective precautions, without the need for a large clean room with an operator to be protected therein.
  • system according to the invention can not only be used to fill flowable, ie pulverulent and granular substances, but also liquid and paste-like substances.
  • the container according to the invention is subdivided into two horizontally superimposed chambers, the holder of the sack being provided on the flange attaching the inlet opening in the upper chamber, while the barrel container is located in the lower chamber.
  • the two chambers are connected to one another in that the sack protrudes through the opening which connects the upper chamber to the lower one.
  • the two chambers are separated by first inserting the tied sack into the barrel container by hand, as well as the barrel container's safety cover and then closing the barrel container with a closure lid. Then the barrel container is lowered and the opening between the two chambers is closed.
  • the safety cover which can be pivoted in the container, in which the closed barrel container is now available for removal through a corresponding loading opening.
  • This division of the container into two horizontally superimposed chambers, the connection of which can be closed by a safety cover, has the advantage that any contamination of the upper chamber cannot be dragged into the lower chamber.
  • the container according to the invention can also be combined with other containers that are hermetically sealed to this container connect. This means that previously described work processes can be automated. For example, the filled drum container can then no longer be removed by hand via a loading opening, but this drum container is mechanically conveyed into another container, which can have a pressure or cleaning lock.
  • a cone screw mixer 1 which has a mixing screw in its interior in a manner known per se, which rotates around the container wall and rotates itself.
  • the bottom opening of the conical screw mixer is formed by a ball segment valve 2, on the underside of which there is an outlet opening 3, which is closed from below by a metering valve 4.
  • This metering valve 4 sits directly on a flange 9 of a container 5, which is designed as a hermetically sealed clean room container.
  • the container 5 has corresponding windows 22 and is provided with through openings 23 which are connected hermetically from the outside environment by so-called gloves.
  • a flange 9 which is designed as a double flange, is attached to the underside of the inlet opening 6. This is necessary for ventilation in the interior of the bag 13 to be filled.
  • an inflatable sealing part 10 is arranged, which essentially consists of a pair of flanges 11, between which an inflatable sealing tube 12 is received.
  • the upper side of a bag 13 to be filled is arranged on the outer circumference of the sealing tube 12.
  • a barrel container 18 In the interior of the container 5, a barrel container 18 is arranged, which is double-walled.
  • the outer shell consists of a relatively resistant material and is covered on the inside by a safety shell 19.
  • the two shells are held together by a closure flange 28.
  • the barrel container 18 stands on a weighing and lifting system 21.
  • the sack 13 to be filled is arranged in the interior of the barrel container 18, the barrel container 18 protruding through an opening 27 in a plate 29 of the container 5.
  • the container 5 is divided into two superimposed chambers 30, 31, which are connected to one another by the closable opening 27.
  • This opening 27 can be closed by a security cover 24 which is pivotably mounted in the container 5.
  • the barrel container 18 can through a loading opening 20 in the lower Chamber 31 are removed from the container 5 and a further empty barrel container, which carries an empty sack to be filled, is introduced via this loading opening 20.
  • the filling is stopped and air is first pumped out of the interior of the sack 13 via the vent line 26 which attaches to the flange 9 in order to evacuate this sack.
  • the sack contracts and can be tied off.
  • the closure flange 28 is removed and the safety cover 19 is also tied and stuffed into the barrel container 18.
  • the barrel container 18 is lowered and the barrel container 18 is closed via the access opening 23 via a lid loosely arranged in the container. This lid is not shown in the picture.
  • the safety cover 24, which rests on the plate 29, is then pivoted into the closed position so that it covers the opening 27 in the plate 29 and no further medium can trickle or flow from above onto the now closed drum container 18.
  • the upper chamber 30 is thus separated from the lower chamber 31.
  • the closed drum container 18 is removed from the container 5 and a new drum container 18 is placed on the weighing and lifting system 21 promoted.
  • the loading opening 20 is then closed again and the lid of the barrel container 18 is removed. Then the weighing and lifting system 21 is then acted on, so that the barrel container 19 can be moved through the opening 27 which has now been freed from the safety cover 24 in the filling position. A new filling process then takes place, i.e. the sack 13 to be filled is now placed manually through the access openings 23 on the inflatable sealing part 10, which is still deflated and which is then inflated in order to hold this upper edge of the sack 13.
  • a suction and venting is also provided on the container, which is shown in the form of a pipe flange 7 in the figure.
  • a swirl valve 8 is provided, which is not shown in the drawing.
  • This vortex valve 8 ensures that in the event of a leak in the container 5, the amount of air is sucked out through the vortex valve 8 and the negative pressure in the container is increased so that no medium can get outside the container 5.
  • a control 25 is also arranged, in which the corresponding control and monitoring devices are arranged, such as. B. valves, controls, scales and the like.
  • the container 5 according to the invention cannot necessarily work with a cone screw mixer, but with any other container in which the dangerous medium to be filled is arranged.
  • the containers generally described here other process engineering apparatuses are of course also possible.
