Description

Die vorliegende Erfindung betrifft eine Abfüllanlage nach dem Oberbegriff des Patentanspruchs 1.The present invention relates to a bottling plant according to the preamble of claim 1.

Eine derartige Abfüllanlage ist in der Form bekannt geworden, daß man hochwirksame pulverförmige oder fließfähige Medien beim Umfüllen oder Verpacken insbesondere in der Pharmazie und in der chemischen Verfahrenstechnik bisher in einem Reinraum abpacken mußte.Such a bottling plant has become known in the form that highly effective powdery or flowable media have had to be packed in a clean room when decanting or packaging, in particular in pharmacy and in chemical process engineering.

Derartige Medien werden beispielsweise in Schneckenmischern, Filteranordnungen, Rührwerksbehältern und dergleichen zubereitet und müssen dann unter hermetisch dichten Bedingungen abgefüllt werden. Bisher ist es lediglich bekannt, eine derartige Abfüllung in einem Reinraum vorzunehmen, um das Personal, welches die Abfülleinrichtung bedient, vor der Exposition gegenüber diesen gefährlichen Medien zu schützen.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.

Hierzu war es zum Teil erforderlich, daß das Bedienungspersonal der Abfüllanlage Schutzanzüge tragen mußte, um nicht mit den gefährlichen Medien in Berührung zu kommen.For this it was partly necessary that the operators of the bottling plant had to wear protective suits in order not to come into contact with the dangerous media.

Ebenso mußte der Reinraum mit einer entsprechenden Fremdbelüftung versehen werden, genauso wie eventuell die Raumanzüge des Bedienungspersonals mit entsprechenden Atmungshelmen und einer Fremdbelüftung versehen werden mußten.Likewise, the clean room had to be provided with appropriate external ventilation, just as the room suits of the operating personnel had to be provided with appropriate breathing helmets and external ventilation.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Abfüllanlage der eingangs genannten Art so weiterzubilden, daß unter wesentlich geringeren Kosten und unter Ausschluß einer Personalgefährdung die Abfüllung gefährlicher Medien erfolgen kann.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.

Zur Lösung der gestellten Aufgabe ist die Erfindung durch die technische Lehre des Patentanspruchs 1 gekennzeichnet.To achieve the object, the invention is based on the technical Teaching of claim 1 characterized.

Wesentliches Merkmal der vorliegenden Erfindung ist, daß die Abfüllung nun in einem hermetisch abgeschlossenen Behälter erfolgt, an dessen Oberseite eine Einlauföffnung für das zu verpackende, gefährliche Medium angeordnet ist, und in dessen Innenraum die eigentliche Abfüllanlage angeordnet ist.An essential feature of the present invention is that the filling is now carried out in a hermetically sealed container, on the top of which there is an inlet opening for the dangerous medium to be packed, and in the interior of which the actual filling system is arranged.

Wichtig ist, daß an diesem Behälter entsprechende Fenster angeordnet sind, um den Abfüllvorgang zu beobachten und ferner ist wichtig, daß in dem Behälter Durchgriffsöffnungen vorhanden sind, die mit Schutzhandschuhen verbunden sind, um dem Personal eine Manipulation der im Innenraum des Behälters angeordneten Füll- und Wiegeeinheit zu gewährleisten.It is important that appropriate windows are arranged on this container in order to observe the filling process and it is also important that through openings are provided in the container, which are connected with protective gloves, in order for the personnel to manipulate the filling and arranged inside the container Ensure weighing unit.

Vorteil dieser Anordnung ist, daß keine besonderen Schutzausrüstungen für das Bedienungspersonal erforderlich sind und daß ebenso ein sogenannter clean-room entfallen kann. Mit dem neuerungsgemäßen Behälter erfolgt eine zuverlässige Abschottung von den gefährlichen Medien und es wird eine sichere Beschickung und Entleerung gewährleistet.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.

Hierbei wird es bevorzugt, wenn der Behälter mit einem Unterdrucksystem verbunden ist, welches im Falle eines Schadens an der Dichtheit dieses Behälters einen Schadstoffaustritt bei Störungen verhindert.It is preferred here if the container is connected to a vacuum system which, in the event of damage to the tightness of this container, prevents harmful substances from escaping in the event of faults.

Ebenso kann der Behälter leicht von innen gereinigt werden und es gibt beim Wechsel des Verpackungsmediums nur geringe Unterbrechungszeiten.The container can also be easily cleaned from the inside and there are only short interruptions when changing the packaging medium.

Insbesondere werden mit einem derartigen Behälter nur noch niedrige Investitions- und Betriebskosten verursacht.In particular, such a container causes only low investment and operating costs.

Die oben beschriebenen Medien können alle schütt- und fließfähigen Medien sein, insbesondere aber z. B. pulverförmige Medien jeglicher Art.The media described above can be all pourable and flowable media, but especially z. B. powdery media of any kind.

Hierbei ist vorgesehen, daß die zur Herstellung der Medien vorgesehene Fabrikationseinrichtung, z. B. ein Konus-Schneckenmischer, direkt mit seiner Auslauföffnung an der Einlauföffnung des Behälters aufsitzt.It is provided here that 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.

Die Dosierung des Mediums, d. h. also die Menge des Mediums, die in den Behälter einlaufen soll, wird bevorzugt auf der Herstellungsseite bewerkstelligt. Hierbei kann es vorgesehen sein, daß an der Unterseite des Konus-Schneckenmischers ein entsprechendes Kugelsegmentventil vorgesehen ist, welches eine bestimmte Menge des Mediums in eine Auslauföffnung fließen läßt, an deren Unterseite ein Dosierventil angeordnet ist.The dosage of the medium, i.e. H. that is, the amount of the 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.

Das besagte Kugelsegmentventil dient also nur zur hermetischen Schließung der Bodenöffnung dieses Konus-Schneckenmischers, während die eigentliche Dosierung durch das noch unterhalb in Fließrichtung des Mediums angeordnete Dosierventil erfolgt.Said ball segment valve is therefore only used for hermetically closing the bottom opening of this conical screw mixer, while the actual metering takes place through the metering valve which is still arranged below in the direction of flow of the medium.

Dieses Dosierventil ist unmittelbar auf der Einlauföffnung des Behälters aufgesetzt.This metering valve is placed directly on the inlet opening of the container.

Von dieser Einlauföffnung ausgehend ist nun die Verpackungs- und Wiegeeinheit in dem Behälter selbst angeordnet.Starting from this inlet opening, the packaging and weighing unit is now arranged in the container itself.

Hier gibt es verschiedene Möglichkeiten zur Ausbildung derartiger Verpackungs- und Wiegeeinheiten.There are various options for the formation of such packaging and weighing units.

In einer ersten Ausführungsform besteht die Verpackungs- und Wiegeeinheit aus einem einlaufseitig angeordneten aufblasbaren Dichtungsteil, welches um den sich an die Einlauföffnung anschließenden Flansch eine hermetische Abdichtung bildet für einen an diesem Dichtungsteil anschließenden Sack.In a first embodiment, the packaging and weighing unit consists of an inflatable sealing part arranged on the inlet side, which forms a hermetic seal around the flange adjoining the inlet opening for a sack adjoining this sealing part.

Der Sack seinerseits kann in einem Faßcontainer gelagert sein, was aus Sicherungsgründen bevorzugt wird.The sack in turn can be stored in a barrel container, which is preferred for security reasons.

Der Faßcontainer kann ebenfalls doppelwandig ausgebildet sein, nämlich aus einer relativ starren Außenwand, die z. B. aus Kunststoff, Papier oder Metall besteht und aus einer inneren Sicherheitshülle, welche die innere Doppelwandung dieses Faßcontainers darstellt. In diesen doppelwandig ausgebildeten Faßcontainer wird nun der Sack eingehängt und mit seiner oberen Öffnung an dem aufblasbaren Dichtungsteil angehängt. Dieses Dichtungsteil wird nun aufgeblasen und hält den Sack abdichtend an der Unterseite des Flansches, der mit der Einlauföffnung verbunden ist.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.

Nach erfolgtem Anschluß dieses zu befüllenden Sackes wird nun zunächst das Kugelsegmentventil geöffnet und sonach dann das Dosierventil in Betrieb gesetzt, um eine bestimmte, abgemessene Menge des gefährlichen Mediums über die nun geöffnete Einlauföffnung und den Flansch in den Sack fließen zu lassen.After this sack to be filled has been connected, the ball segment valve is first opened and then the metering valve is then put into operation in order to allow a certain, measured quantity of the dangerous medium to flow into the sack via the now opened inlet opening and the flange.

Das Medium sammelt sich nun im Innenraum des Sackes, der im Faßcontainer sitzt, an, bis zu einem vorgeschriebenen Gewicht, das durch ein Wiege- und Hebesystem festgestellt wird, auf dem der gesamte Faßcontainer mit dem zu befüllenden Sack aufsitzt.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.

Nach dem Erreichen des erforderlichen Gewichtes wird erst das Dosierventil geschlossen, dann wird überschüssige Luft aus dem Innenraum des Sackes durch ein an dem Flansch unterhalb der Einlauföffnung angesetzten Entlüftungsleitung abgesaugt. Dabei zieht sich der Sack zusammen und kann verschlossen werden, wobei das aufblasbare Dichtungsteil noch in Funktion ist und den Sack hermetisch dicht an der Unterseite des Flansches hält. Der Sack kann nun abgebunden werden und wird abgeschnitten. Der obere Teil des Sackes bleibt dann an der aufblasbaren Dichtung hängen, während der untere, nun abgebundene Sack in dem Faßcontainer ruht.After the required weight has been reached, 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 in operation and holding the sack hermetically tight to the underside of the flange. The sack can now be tied off and cut off. The upper part of the sack then remains attached to the inflatable seal, while the lower, now tied sack rests in the barrel container.

Über die am Behälter angeordneten Durchgriffsöffnungen wird nun der Sack per Hand in den Faßcontainer hineingesteckt, wobei er dann von der Sicherheitshülle umgeben wird.The sack is then 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.

Danach wird der Faßcontainer, der auf dem Wiege- und Hebesystem ruht, abgesenkt und ein im Behälter schwenkbar angeordneter Sicherheitsdeckel wird auf die Öffnung im Behälter geschwenkt und verschließt diese Öffnung, durch welche vorher der Faßcontainer hindurchragte.Then the barrel container, which rests on the weighing and lifting system, is lowered and a safety lid which is pivotably arranged in the container is pivoted onto the opening in the container and closes this opening, through which the barrel container previously protruded.

Dieser Sicherheitsdeckel soll ein unzulässiges Nachrieseln des Mediums nach unten bei entferntem Sack verhindern.This safety cover is intended to prevent the medium from trickling downwards with the sack removed.

Der Behälter steht nach wie vor unter Unterdruck und es wird die Beladeöffnung an der Seitenwand des Behälters geöffnet und der Faßcontainer mit dem darin enthaltenen, befüllten Sack kann aus dem Behälter entnommen werden.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.

Es wird dann auf das Wiege- und Hebesystem ein neuer Behälter aufgesetzt, der einen zu befüllenden Sack trägt.A new container is then placed on the weighing and lifting system, which carries a sack to be filled.

Die Beladeöffnung wird geschlossen und der Sicherheitsdeckel wird von der Öffnung im Behälter weggeschwenkt, so daß beim Anheben des Faßcontainers dieser durch eine Öffnung in den Behälter hindurchragt.The loading opening is closed and the safety cover 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.

Von außen wird nun von Handbetätigung der neue, zu befüllende Sack an dem ausblasbaren Dichtungsteil angeschlossen und dieses wird aufgeblasen.From the outside, the new bag to be filled is now connected to the blow-out sealing part by hand and this is inflated.

Der neue Sack ist nun zur Befüllung bereit. Es erfolgt dann ein neuer Befüllungsvorgang, wie oben stehend beschrieben.The new sack is now ready to be filled. A new filling process then takes place, as described above.

Wesentliches Merkmal der vorliegenden Erfindung ist also, daß das gesamte Abfüllen des Mediums unter Reinraumbedingungen und unter größten Schutzvorkehrungen erfolgen kann, ohne daß ein großer Reinraum mit einem darin zu schützenden Bedienungspersonal notwendig ist.An essential feature of the present invention is therefore that the entire filling of the medium can take place under clean room conditions and under the greatest protective precautions, without the need for a large clean room with operating personnel to be protected therein.

Es wird darauf hingewiesen, daß mit der erfindungsgemäßen Anlage nicht nur fließfähige, d.h. pulverförmige und granulatförmige Stoffe abgefüllt werden können, sondern auch flüssige Stoffe und pastenförmige Stoffe.It is pointed out that the 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.

Wesentlich ist ferner, daß der erfindungsgemäße Behälter in zwei horizontal übereinanderliegenden Kammern unterteilt ist, wobei in der oberen Kammer die Halterung des Sackes an dem die Einlauföffnung ansetzenden Flansch vorgesehen ist, während in der unteren Kammer der Faßcontainer sitzt. Während der Befüllung des Sackes sind die beiden Kammern miteinander verbunden, dadurch, daß der Sack durch die Öffnung hindurchragt, welche die obere Kammer mit der unteren verbindet.It is also essential that 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. During the filling of the sack, 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.

Nach erfolgter Evakuierung des befüllten Sackes und nach dessen Abbinden und Abschneiden erfolgt dann eine Trennung beider Kammern dadurch, daß zunächst von Hand der abgebundene Sack in den Faßcontainer gesteckt wird, ebenso wie die Sicherheitshülle des Faßcontainers und daß dann der Faßcontainer durch einen Verschlußdeckel verschlossen wird. Danach wird der Faßcontainer abgesenkt und die Öffnung zwischen den beiden Kammern wird verschlossen.After the filled sack has been evacuated and after it has been tied off and cut off, the two compartments are separated by first inserting the tied sack into the barrel container by hand, as well as the safety container of the barrel container, and then closing the barrel container by a closure lid. Then the barrel container is lowered and the opening between the two chambers is closed.

Nun ist die obere Kammer des Behälters über den im Behälter schwenkbar angeordneten Sicherheitsdeckel von der unteren Kammer getrennt, in der nun der verschlossene Faßcontainer zur Entnahme durch eine entsprechende Beladeöffnung zur Verfügung steht.Now the upper chamber of the container is separated from the lower chamber by the safety cover pivotably arranged in the container, in which the closed barrel container is now available for removal through a corresponding loading opening.

Durch diese Aufteilung des Behälters in zwei horizontal übereinanderliegende Kammern, deren Verbindung durch einen Sicherheitsdeckel verschlossen werden kann, wird der Vorteil erreicht, daß eine eventuelle Verschmutzung der oberen Kammer nicht in die untere Kammer hineingeschleppt werden kann.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.

Der erfindungsgemäße Behälter kann noch mit weiteren Behältern kombiniert werden, die hermetisch dicht an diesem Behälter anschließen. Damit können vorher beschriebene Arbeitsvorgänge automatisiert werden. Beispielsweise kann das Entnehmen des befüllten Faßcontainers dann nicht mehr von Hand über eine Beladeöffnung erfolgen, sondern dieser Faßcontainer wird maschinell in einen weiteren Behälter befördert, der eine Druck- oder Reinigungsschleuse aufweisen kann.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 barrel container can then no longer be removed manually via a loading opening, but this barrel container is mechanically conveyed into another container, which can have a pressure or cleaning lock.

Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

Alle in den Unterlagen - einschließlich der Zusammenfassung - offenbarten Angaben und Merkmale, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All information and features disclosed in the documents - including the summary -, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are new to the prior art, individually or in combination.

Die Erfindung wird nun anhand eines Ausführungsbeispieles näher beschrieben.The invention will now be described in more detail using an exemplary embodiment.

In der Abbildung ist lediglich der untere Teil eines Konus-Schneckenmischers 1 dargestellt, der in seinem Innenraum in an sich bekannter Weise eine Mischschnecke aufweist, die an der Behälterwandung umläuft und selbst in sich dreht.In the figure, only the lower part of a cone screw mixer 1 is shown, which has a mixing screw in its interior in a manner known per se, which rotates around the container wall and rotates itself.

Die Bodenöffnung des Konus-Schneckenmischers wird durch ein Kugelsegmentventil 2 gebildet, an dessen Unterseite sich eine Auslauföffnung 3 anschließt, die von unten her durch ein Dosierventil 4 verschlossen ist. Dieses Dosierventil 4 sitzt unmittelbar auf einem Flansch 9 eines Behälters 5 auf, der als hermetisch dichter Reinraum-Behälter ausgebildet ist.The bottom opening of the cone 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.

Hierzu weist der Behälter 5 entsprechende Fenster 22 auf und ist mit Durchgriffsöffnungen 23 versehen, die nach innen hin durch sogenannte Handschuhe hermetisch dicht von der Außenumgebung angeschlossen sind.For this purpose, the container 5 has corresponding windows 22 and is provided with through openings 23 which are connected to the outside in a hermetically sealed manner by so-called gloves.

In dem Behälter 5 erfolgt der eigentliche Abfüll- und Wiegevorgang für die gefährlichen Medien, so daß mit Sicherheit vermieden wird, daß ein derartiges Medium in die Umgebung gelangt.The actual filling and weighing process for the dangerous media takes place in the container 5, so that it is avoided with certainty that such a medium gets into the environment.

An der Unterseite der Einlauföffnung 6 ist hierbei ein Flansch 9 angebracht, der als Doppelflansch ausgebildet ist. Dies ist für eine Entlüftung im Innenraum des zu befüllenden Sackes 13 notwendig.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.

Am Außenumfang des Flansches 9 ist hierbei ein aufblasbares Dichtungsteil 10 angeordnet, welches im wesentlichen aus einem Flanschpaar 11 besteht, zwischen dem ein aufblasbarer Dichtungsschlauch 12 aufgenommen ist.On the outer circumference of the flange 9, 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.

Am Außenumfang des Dichtungsschlauches 12 ist die obere Seite eines zu befüllenden Sackes 13 angeordnet.The upper side of a bag 13 to be filled is arranged on the outer circumference of the sealing tube 12.

Im Innenraum des Behälters 5 ist ein Faßcontainer 18 angeordnet, der doppelwandig ausgebildet ist. Die Außenhülle besteht aus einem relativ widerstandsfähigem Material und ist innen von einer Sicherheitshülle 19 abgedeckt.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.

Die beiden Hüllen werden von einem Verschlußflansch 28 zusammengehalten.The two shells are held together by a closure flange 28.

Der Faßcontainer 18 steht auf einem Wiege- und Hebesystem 21.The barrel container 18 stands on a weighing and lifting system 21.

Im Innenraum des Faßcontainers 18 ist der zu befüllende Sack 13 angeordnet, wobei der Faßcontainer 18 durch eine Öffnung 27 in einer Platte 29 des Behälters 5 hindurchragt. HIerdurch wird der Behälter 5 in zwei übereinanderliegende Kammern 30,31 unterteilt, die durch die verschließbare Öffnung 27 miteinander verbunden sind.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. As a result, the container 5 is divided into two superimposed chambers 30, 31, which are connected to one another by the closable opening 27.

Diese Öffnung 27 ist durch einen schwenkbar im Behälter 5 angebrachten Sicherheitsdeckel 24 verschließbar.This opening 27 can be closed by a security cover 24 which is pivotably mounted in the container 5.

Der Faßcontainer 18 kann durch eine Beladeöffnung 20 in der unteren Kammer 31 aus dem Behälter 5 entnommen werden und über diese Beladeöffnung 20 ein weiterer, leerer Faßcontainer, der einen leeren, zu befüllenden Sack trägt, eingeführt werden.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.

Der Abfüllvorgang erfolgt nun folgendermaßen:
Nachdem das Kugelsegment-Ventil 2 geöffnet ist und das Dosierventil 4 in Betrieb ist, wird eine genau abgemessene Menge des Produktes 15 aus dem Konus-Schneckenmischer über das Dosierventil 4 und die Einlauföffnung 6 in den Flansch 9 hineinbefördert, wobei der Produktstrom 14 sich in Pfeilrichtung 17 in den zu befüllenden Sack 13 ergießt.The filling process is now carried out as follows:
After the ball segment valve 2 is opened and the metering valve 4 is in operation, a precisely measured amount of the product 15 is conveyed out of the cone screw mixer via the metering valve 4 and the inlet opening 6 into the flange 9, the product stream 14 moving in the direction of the arrow 17 pours into the bag 13 to be filled.

Sobald das Wiege- und Hebesystem 21 das erforderliche Befüllungsgewicht festgestellt hat, wird die Befüllung gestoppt und es wird zunächst über die eine Entlüftungsleitung 26, die an dem Flansch 9 ansetzt, Luft aus dem Innenraum des Sackes 13 herausgepumpt, um diesen Sack zu evakuieren. Der Sack zieht sich demzufolge zusammen und kann abgebunden werden. Nach dem Abbinden wird er im Zwischenraum zwischen der Unterkante es Flansches 9 und der Abbindestelle abgeschnitten und der abgeschnittene und zugebundene Teil wird nun vollständig in den Faßcontainer 18 hineingestopft. Der Verschlußflansch 28 wird abgenommen und die Sicherheitshülle 19 wird ebenfalls abgebunden und in den Faßcontainer 18 hineingestopft. Mit dem Wiege- und Hebesystem 21 wird der Faßcontainer 18 abgesenkt und über die Durchgriffsöffnung 23 wird der Faßcontainer 18 über einen im Behälter lose angeordneten Deckel verschlossen. Dieser Deckel ist in der Abbildung nicht dargestellt.As soon as the weighing and lifting system 21 has determined the required filling weight, 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. As a result, the sack contracts and can be tied off. After tying it is cut off in the space between the lower edge of the flange 9 and the tying point and the cut and tied part is now completely stuffed into the barrel container 18. The closure flange 28 is removed and the safety cover 19 is also tied off and plugged into the barrel container 18. With the weighing and lifting system 21, 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.

Sonach wird der Sicherheitsdeckel 24, der auf der Platte 29 ruht, in Schließstellung verschwenkt, so daß er die Öffnung 27 in der Platte 29 abdeckt und auf den nun verschlossenen Faßcontainer 18 kein weiteres Medium mehr von oben nachrieseln oder fließen kann. Damit ist die obere Kammer 30 von der unteren Kammer 31 getrennt.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 onto the now closed drum container 18 from above. The upper chamber 30 is thus separated from the lower chamber 31.

Über die Beladeöffnung 20 in der unteren Kammer 31, die nun geöffnet ist, wird der verschlossene Faßcontainer 18 aus dem Behälter 5 entnommen und es wird ein neuer Faßcontainer 18 auf das Wiege- und Hebesystem 21 befördert.Via the loading opening 20 in the lower chamber 31, which is now open, 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.

Es wird dann die Beladeöffnung 20 wieder verschlossen und der Deckel des Faßcontainers 18 wird abgenommen. Sonach wird dann das Wiege- und Hebesystem 21 beaufschlagt, so daß der Faßcontainer 19 in Befüllposition durch die nun wieder von dem Sicherheitsdeckel 24 befreite Öffnung 27 hindurchgefahren werden kann. Es erfolgt dann ein neuer Befüllungsvorgang, d.h. der zu befülllende Sack 13 wird nun manuell über die Durchgriffsöffnungen 23 an dem aufblasbaren Dichtungsteil 10 angelegt, welches noch entleert ist und welches dann nachfolgend aufgeblasen wird, um diesen oberen Rand des Sackes 13 zu halten.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 drum 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.

Aus Sicherheitsgründen ist an dem Behälter noch eine Absaugung und Entlüftung vorgesehen, die in Form eines Rohrflansches 7 in der Abbildung dargestellt ist.For safety reasons, a suction and venting is provided on the container, which is shown in the form of a pipe flange 7 in the figure.

Ferner ist ein Wirbelventil 8 vorgesehen, welches nicht näher zeichnerisch dargestellt ist. Dieses Wirbelventil 8 sorgt dafür, daß bei einer Leckage im Behälter 5 die Luftmenge durch das Wirbelventil 8 abgesaugt wird und der Unterdruck in dem Behälter so erhöht wird, daß kein Medium außerhalb des Behälters 5 gelangen kann. An der Oberseite des Behälters 5 ist noch eine Steuerung 25 angeordnet, in der die entsprechenden Steuer- und Kontrolleinrichtungen angeordnet sind, wie z. B. Ventile, Steuerelemente, Waage und dergleichen.Furthermore, 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 through the vortex valve 8 and the negative pressure in the container is increased so that no medium can get outside the container 5. At the top of the container 5, a controller 25 is also arranged, in which the corresponding control and monitoring devices are arranged, such as. B. valves, controls, scales and the like.

Es wird darauf hingewiesen, daß der erfindungsgemäße Behälter 5 nicht notwendiger Weise mit einem Konus-Schneckenmischer zusammenarbeiten kann, sondern mit beliebigen anderen Behältern, in welchen das abzufüllende, gefährliche Medium angeordnet ist. Statt der hier allgemein beschriebenen Behälter kommen selbstverständlich auch andere verfahrenstechnische Apparate in Betracht.It is pointed out that 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. Instead of the containers generally described here, other process engineering apparatuses are of course also possible.
