Description

Die Erfindung betrifft eine Anlage zum Abfüllen mehrerer Einzelkomponenten eines Mehrstoffgemisches nach dem Oberbegriff des Anspruchs 1.The invention relates to a system for filling several individual components of a multi-substance mixture according to the preamble of claim 1.

Bekannte Abfüll- und Verpackungsanlagen für Einzelkomponenten bestehen aus Einkomponentenbehältern mit einer zugeordneten Mehrkomponentenwaage. Die Herstellung einer bestimmten Stoffzusammensetzung aus den Einzelkomponenten geschieht dadurch, daß durch additives Zuwiegen der einzelnen Komponenten auf einer Waage das Stoffgemisch hergestellt und anschließend verpackt wird. Insbesondere das Verwiegen von Chemikalien in kleinen Mengen für die Medizintechnik oder sonstige Gebiete muß mit hochpräzisen Wiegeeinrichtungen vorgenommen werden. In jeder abzuwiegenden Charge können dabei aber erhebliche Gewichtsunterschiede der einzelnen Stoffkomponenten auftreten, d. h. es wird eine große Menge des ersten Stoffes beispielsweise mit einer sehr kleinen Menge eines zweiten Stoffes vermischt. Die zu verwendenden Wiegeeinrichtungen müssen hierfür sehr große Gewichtsbereiche überdecken, was zum einen einen hohen technischen Aufwand und zum anderen eine letztlich nicht vermeidbare Ungenauigkeit durch zu große Gewichtsbereiche mit sich bringt. Weiterhin hat das additive Verwiegen von Einzelkomponenten den Nachteil, daß der Wiegevorgang sehr lange dauert, da dieser erst abgeschlossen ist, wenn alle Einzelkomponenten auf der Mehrkomponentenwaage abgewogen sind. Es könnten zwar mehrere derartige Mehrkomponentenwaagen bzw.
Mehrkomponentenabfüllstationen hintereinander angeordnet sein. Diese können jedoch nicht im Verbund miteinander arbeiten, da jede Abfüllstation einen in sich abgeschlossenen Arbeitsvorgang für das komplette Abwiegen und Abfüllen der Einzelkomponenten vornimmt.Known filling and packaging systems for individual components consist of one-component containers with an assigned multi-component scale. The production of a certain composition of substances from the individual components takes place in that the additive weighing of the individual components on a balance produces the mixture of substances and then packs it. In particular, the weighing of chemicals in small quantities for medical technology or other areas must be carried out with high-precision weighing equipment. In each batch to be weighed, however, considerable weight differences of the individual substance components can occur, ie a large amount of the first substance is mixed, for example, with a very small amount of a second substance. For this purpose, the weighing devices to be used must cover very large weight ranges, which on the one hand entails a high technical outlay and on the other hand an inaccuracy that is ultimately unavoidable due to excessively large weight ranges. Additive weighing of individual components also has the disadvantage that the weighing process takes a very long time because of this is only completed when all individual components on the multi-component scale have been weighed. Several such multi-component scales or
Multi-component filling stations can be arranged one behind the other. However, these cannot work together because each filling station carries out a self-contained process for the complete weighing and filling of the individual components.

Aus der DE-B-1 250 769 ist eine kombinierte Austrags-, Wiege- und Übergabevorrichtung der gattungsgemäßen Art bekannt geworden, die eine Wiegeeinrichtung mit einem Wiegebehälter umfaßt, der eine, in Abhängigkeit von der Wiegeeinrichtung regelbarer und elektrisch gesteuerter Schneckenförderer zur Gewichtsregulierung vorgeschaltet ist, wobei mehrere Schnecken einem einzigen Wiegebehälter zugeordnet sind. Die bekannte Anordnung führt jedoch nicht zu einer nach heutigen Anforderungen befriedigenden Lösung.From DE-B-1 250 769 a combined discharge, weighing and transfer device of the generic type has become known which comprises a weighing device with a weighing container which is connected upstream of an electrically controlled screw conveyor which is adjustable as a function of the weighing device for weight regulation , wherein several screws are assigned to a single weighing container. However, the known arrangement does not lead to a solution which is satisfactory according to today's requirements.

Aus der weiterhin bekannten US-A-2 638 305 ist eine Verwiegeeinrichtung bekannt geworden, die nach dem sogenannten additiven Verwiegungsprinzip arbeitet. Eine derartige additive Verwiegung erfolgt stets mit einer einzigen Waage, was den Nachteil hat, daß eine solche Waage nicht gleichermaßen präzise kleinste und größte Mengen von einzelnen Komponenten genauestens erfassen kann.From the further known US-A-2 638 305 a weighing device has become known which works according to the so-called additive weighing principle. Such additive weighing is always carried out with a single scale, which has the disadvantage that such a scale cannot precisely measure the smallest and largest amounts of individual components with equal precision.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Anlage zum Abfüllen mehrerer Einzelkomponenten eines Mehrstoffgemisches vorzuschlagen, die höchsten Ansprüchen an die Genauigkeit, Reinheit und Zuverlässigkeit des abgefüllten Mehrstoffgemisches entspricht. Insbesondere sollen die vorgenannten Nachteile vermieden und ein hochgenaues Abwiegen und Zusammenführen von Einzelkomponenten bei einer hohen Durchsatzleistung bzw. Abfüllgeschwindigkeit ermöglicht werden.The invention has for its object to propose an improved system for filling several individual components of a multi-substance mixture, which corresponds to the highest demands on the accuracy, purity and reliability of the filled multi-substance mixture. In particular, the aforementioned disadvantages are to be avoided and a highly precise weighing and merging of individual components with a high throughput or filling speed should be made possible.

Diese Aufgabe wird ausgehend von einer Anlage der einleitend bezeichneten Art erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved on the basis of a system of the type described in the introduction by the characterizing features of claim 1.

Der vorliegenden Erfindung liegt der Kerngedanke zugrunde, im Bereich jedes Vorratsbehälters einer jeweiligen Einzelkomponente eine eigene komibinierte Austrags-, Wiege- und Übergabevorrichtung vorzusehen, die an die jeweiligen Einzelkomponente angepaßt ist. Hierfür sind ein zusätzlicher Schneckenförderer für eine hochpräzise Gewichtsfeinregulierung vorgesehen, wobei die präzise Abgabe jeder Einzelkomponente dazu beiträgt, daß ein Höchstmaß an Präzision bei der Abfüllung des Gesamtgemisches erzielt wird.The present invention is based on the core idea of providing a separate combined discharge, weighing and transfer device in the area of each storage container of a respective individual component, which is adapted to the respective individual component. For this purpose, an additional screw conveyor for high-precision fine adjustment is provided, the precise delivery of each individual component helping to achieve the highest level of precision when filling the entire mixture.

Der Erfindung liegt ferner der Grundgedanke zugrunde, daß ein äußerst präziser Wiegevorgang in wirtschaftlich vertretenbarem Maße und mit hoher Geschwindigkeit nur mit einer Einkomponentenwiegeeinrichtung sinnvoll ist. Deshalb schlägt die Erfindung die Hintereinanderschaltung von Einkomponentenbehältern mit jeweils zugehöriger Abfüllvorrichtung für aus mehreren Einzelstoffen bestehende Rezepturen vor. Eine solche Abfüllvorrichtung besteht aus einer, ggf. speziell an den abzufüllenden Stoff angepaßten Austragsvorrichtung und einer nachgeschalteten Wiegeeinrichtung sowie einer Übergabevorrichtung in Gestalt eines um 180° schwenkbaren Wiegebehälters zur Übergabe der abgewogenen Einzelstoffes in einen Behälter. Dieser Behälter wird dann einer nächsten Abfüllstation mit einem weiteren Einzelstoff taktweise zugeführt, wobei ggf. auch die Behälter stationär und die Aufschüttbehälter mit zugehöriger Austrags-, Wiege- und Übergabevorrichtung an diesen vorbeigetaktet werden können. Durch die erfindungsgemäße Anordnung können die einzelnen Stationen jeweils speziell auf den auszutragenden Stoff abgestimmt werden. Beispielsweise ist es möglich, daß eine oder mehrere bestimmte Stationen eine Kühlvorrichtung für temperaturempfindliche Produkte aufweisen oder daß die Austrags- und Wiegevorrichtungen speziell dem jeweiligen Stoff angepaßt sind. Selbstverständlich wird man versuchen eine weitgehende Vereinheitlichung der Einzelbauteile aus Kostengründen anzustreben.The invention is also based on the basic idea that an extremely precise weighing process in an economically justifiable degree and at high speed only makes sense with a one-component weighing device. The invention therefore proposes the series connection of one-component containers, each with an associated filling device, for recipes consisting of several individual substances. Such a filling device consists of a discharge device, possibly specially adapted to the substance to be filled, and a downstream weighing device, as well as a transfer device in the form of a weighing container which can be pivoted through 180 ° for transferring the weighed individual substance into a container. This container is then cyclically fed to a next filling station with a further individual substance, where appropriate also the containers are stationary and the fill-up containers with associated ones Discharge, weighing and transfer device can be clocked past this. With the arrangement according to the invention, the individual stations can each be specifically adapted to the substance to be discharged. For example, it is possible that one or more specific stations have a cooling device for temperature-sensitive products or that the discharge and weighing devices are specially adapted to the respective substance. Of course, one will try to standardize the individual components as far as possible for cost reasons.

Es soll dabei eine möglichst staubfreie Behandlung der Stoffe, insbesondere in der Beschickungsart der Aufschüttbehälter gewährleistet sein. Hierfür werden diese beispielsweise aus Säcken mit einzelnen Chemikalien beschickt, wobei die geleerten Säcke in einem Förderkanal für Leersäcke durch Unterdruck zu einem am Ende der Anlage befindlichen Sackverdichter gefördert werden. Um die eventuell schädlichen Staubbildungen und Dämpfe der Chemikalien abzusaugen, ist eine zusätzliche Saugvorrichtung vorgesehen, die ein Absaugen des Staubes bzw. der Dämpfe ebenfalls über den Sackkanal bewerkstelligt.The aim is to ensure that the materials are treated as dust-free as possible, in particular in the type of loading of the fill-up containers. For this purpose, they are fed, for example, from sacks with individual chemicals, the emptied sacks being conveyed in a conveying channel for empty sacks by negative pressure to a sack compressor located at the end of the system. An additional suction device is provided in order to suction off the possibly harmful dust formation and vapors of the chemicals, which also sucks off the dust or vapors via the sack channel.

In einer bevorzugten Ausführung ist der der Wiegestation zugeordnete, durch Drehung um 180° eine vollständige Entleerung des gewogenen Gutes ermöglichende Wiegebehälter halbkugelförmig. Vorteilhaft ist weiterhin, daß die exakt einzuhaltende Menge durch ein gesteuertes Ventil bestimmt wird.In a preferred embodiment, the weighing container assigned to the weighing station and allowing complete emptying of the weighed goods by rotating through 180 ° is hemispherical. It is also advantageous that the exact amount to be observed is determined by a controlled valve.

Eine weitere besondere Ausbildung, der Erfindung liegt in der speziellen Verschließeinrichtung des verwendeten Kunststoffsacks. Hierzu wird über eine spezielle Vorrichtung der über den Behälterrand umgestülpte obere Rand des Kunststoffsacks durch eine Ansaugung in einen ringförmigen oberen Schlitz eingesaugt und mittels zwei seitlich angeordneten Greifern auseinander gezogen, um danach zusammengeschweißt zu werden.Another special training, the invention lies in the special closing device of the plastic bag used. For this purpose, the upper edge of the plastic sack, which is turned over the container edge, is sucked into a ring-shaped upper slot by means of a suction device and pulled apart by means of two laterally arranged grippers in order to be welded together thereafter.

Vorteilhaft ist weiterhin eine spezielle Beutelabwurfstation mit nachgeschalteter Beutelkontrollwaage.A special bag ejection station with a downstream bag check weigher is also advantageous.

Die erfindungsgemäße Anlage hat den Vorteil, daß sie nahezu vollautomatisch, d. h. normalerweise lediglich mit einer Aufsichtsperson betrieben werden kann. Dabei sind hohe Durchsatzleistungen erreichbar, bei einer äußersten Präzision und Genauigkeit des Abfüll- und Verpackungsvorganges.The system according to the invention has the advantage that it is almost fully automatic, i. H. can usually only be operated with a supervisor. High throughput rates can be achieved with the utmost precision and accuracy of the filling and packaging process.

Die in Fig. 1 in Seitenansicht sowie in Fig. 2 in Draufsicht schematisch dargestellte Anlage 1 dient im speziellen Ausführungsbeispiel zur Abwiegung und Verpackung von Einzelchemikalien. Im allgemeinen werden bis zu ca. 10 Einzelkomponenten zur Herstellung einer bestimmten Rezeptur aus z. B. 44 verschiedenen Einzelkomponenten ausgewählt und zudosiert.Plant 1, shown schematically in side view in FIG. 1 and in plan view in FIG. 2, is used in the special exemplary embodiment for weighing and packaging individual chemicals. In general, up to about 10 individual components for the production of a specific recipe from z. B. 44 different individual components selected and metered.

Längs eines linearen Transportbandes 2 mit darauf verschiebbaren Einzelbehältern 3 sind Abfüllstationen 4 bis 6 hintereinander angeordnet. Wie aus Fig. 2 in Draufsicht ersichtlich, sind an jeder Abfüllstation 4 bis 6 jeweils zwei Aufschüttbehälter 7, 7' paarweise nebeneinander angeordnet, so daß in der Darstellung nach Fig. 2 beispielsweise zweiundzwanzig hintereinander geschaltete Aufschüttbehälterpaare, d. h. insgesamt vierundvierzig Aufschüttbehälter vorgesehen sind. Dabei sind im Ausführungsbeispiel die durchnummerierten Aufschüttbehälter 1 bis 4, (Abfüllstationen 4), die Aufschüttbehälter 5 bis 10 (Abfüllstationen 5) und die Aufschüttbehälter 11 bis 44 (Abfüllstationen 6) in jeweils gleicher Bauweise aufgeführt.Filling stations 4 to 6 are arranged one behind the other along a linear conveyor belt 2 with individual containers 3 displaceable thereon. As can be seen from FIG. 2 in a top view, 4 to 6 each have two filling containers 7, 7 'arranged side by side, so that in the illustration according to FIG. 2, for example, twenty-two pairs of filling containers connected in series, ie a total of forty four filling containers, are provided. The numbered fillers 1 to 4 (filling stations 4), the fillers 5 to 10 (filling stations 5) and the fillers 11 to 44 (filling stations 6) are each listed in the same design in the exemplary embodiment.

Es können demnach vierundvierzig unterschiedliche Stoffe in drei verschiedenen Abfüllstationstypen 4 bis 6 behandelt werden, wobei vorzugsweise aus diesen Stoffen eine Rezeptur ausgewählt wird.Forty-four different substances can therefore be treated in three different filling station types 4 to 6, a recipe preferably being selected from these substances.

Die einzelnen Abfüllstationen 4 bis 6 mit jeweiligen Aufschüttbehältern 7 werden von oben her mit Einzelchemikalien beschickt. Dies geschieht beispielsweise dadurch, daß die in Säcken angelieferten Einzelchemikalien in den jeweiligen Aufschüttbehälter 7 als Silo oder Lagerungsbehälter eingeschüttet werden. Dabei liegt eine Besonderheit der Anlage darin, daß die aufgeschnittenen und entleerten Kunststoffsäcke 8 in einem speziellen Förderkanal 9 für Leersäcke abgesaugt und einem speziellen Sackverdichter 10 zugeführt werden. Gleichzeitig dient der Förderkanal als Absaugkanal für die beim Einfüllen der Chemikalien in den Aufschüttbehälter 7 entstehenden Staubentwicklungen oder Dämpfe. Hierfür ist eine spezielle Absaug- und Filtervorrichtung 11 zur Herstellung des Unterdrucks in der Förderleitung 9 und der Filterung des Staubes bzw. der Dämpfe vorgesehen. Die Absaug- und Filtervorrichtung 11 besteht aus einem, im unteren Bereich trichterförmigen Behälter 12 und einem oberen Zentralfilter 13, sowie einem hinter dem Filter angeordneten Ventilator 14 zur Erzeugung des Unterdrucks.The individual filling stations 4 to 6 with respective fill-up containers 7 are loaded with individual chemicals from above. This happens, for example, in that the individual chemicals delivered in bags are poured into the respective fill-up container 7 as a silo or storage container. A special feature of the system is that the cut and emptied plastic bags 8 are sucked off in a special conveyor channel 9 for empty bags and fed to a special bag compressor 10. At the same time, the conveying channel serves as a suction channel for the dust developments or vapors which arise when the chemicals are poured into the filling container 7. For this purpose, a special suction and filter device 11 is provided for producing the negative pressure in the delivery line 9 and filtering the dust or vapors. The suction and filter device 11 consists of a funnel-shaped container 12 in the lower region and an upper central filter 13, and a fan 14 arranged behind the filter for generating the negative pressure.

Unterhalb des trichterförmigen Behälters 12 ist ein Behälter 15 für Rückstände aus dem Behälter 12 angeordnet. Der Förderkanal 9 durchquert den Behälter 12 und führt über die anschließende Leitung 9' zum Sackverdichter 10. Hier findet mittels eines Schneckenförderers 16 ein Verpressen der leeren Säcke 8 in Ballen 17 oder Emballagen statt.A container 15 for residues from the container 12 is arranged below the funnel-shaped container 12. The conveying channel 9 crosses the container 12 and leads via the subsequent line 9 'to the bag compressor 10. Here, the empty bags 8 are pressed into bales 17 or packaging by means of a screw conveyor 16.

Sofern die Beschickung der einzelnen Aufschüttbehälter 7 mit einzelnen Chemikalien manuell erfolgt, besitzt jeder Aufschüttbehälter 7 in seinem oberen Bereich eine Sackeinschüttgosse 18 mit Einfüllöffnung 19 zum jeweiligen Aufschüttbehälter 7 sowie eine Leersackeinwurfsöffnung 20 zum Förder- und Absaugkanal 9 für die Leersäcke 8.If the individual filler containers 7 are loaded manually with individual chemicals, each filler container 7 has in its upper region a sack filler 18 with a fill opening 19 for the respective filler container 7 and an empty sack insertion opening 20 for the conveying and suction channel 9 for the empty sacks 8.

Die Abfüllstationen 5, d. h. die Einzelbehälter 5 bis 10 sind im Ausführungsbeispiel mit einem äußeren Wasserkühlungsmantel 21 für temperaturempfindliche Chemikalien ausgerüstet.The filling stations 5, d. H. the individual containers 5 to 10 are equipped in the exemplary embodiment with an outer water cooling jacket 21 for temperature-sensitive chemicals.

Jedem Aufschüttbehälter 7 ist in seinem unteren Bereich eine kombinierte Austrags-, Wiege- und Übergabevorrichtung 22 für die Einzelkomponente zugeordnet. Dies gilt auch für die in Fig. 2 dargestellte Anordnung mit nebeneinander positionierten Aufschüttbehälter 7, 7'. Die Austrags-, Wiege- und Übergabevorrichtung des hinteren Aufschüttbehälters 7' ist mit Bezugszeichen 22' gekennzeichnet.A combined discharge, weighing and transfer device 22 for the individual component is assigned to each fill-up container 7 in its lower region. This also applies to the arrangement shown in FIG. 2 with filling containers 7, 7 'positioned next to one another. The discharge, weighing and transfer device of the rear filling container 7 'is identified by reference symbol 22'.

Die in Fig. 1 dargestellte erste Abfüllstationsart 4 (Einzelbehälter 1 bis 4) weist eine Austragsvorrichtung 23 auf, die aus zwei übereinander angeordnete, elektronisch gesteuerte Schneckenförderer 24 und einem elektronisch gesteuerten Absperrventil 25 besteht. Der doppelte Schneckenförderer dient zur Anpassung der Dosierleistung an das zu fördernde Material bzw. an das abzuwiegende Gewicht aus dem Aufschüttbehälter 7.The first filling station type 4 (individual containers 1 to 4) shown in FIG. 1 has a discharge device 23 which consists of two electronically controlled screw conveyors 24 and an electronically controlled shut-off valve 25 arranged one above the other. The double screw conveyor serves to adapt the metering capacity to the material to be conveyed or to the weight to be weighed out of the filling container 7.

Die Schneckendrehzahl des Schneckenförderers 24 wird elektronisch von der darunter angeordneten Wiegevorrichtung 26 geregelt, die an einem, um 180° drehbaren Arm 27 einen halbkugelförmigen Wiegebehälter 28 aufweist. Durch den elektronisch gesteuerten Schneckentransport des Schneckenförderers 24 wird die von der Schnecke in den halbkugelförmigen Behälter 28 geförderte Menge über die Wiegeeinrichtung gemessen und der Schneckenantrieb kontinuierlich gegen Ende des Meßvorgangs zurückgeregelt. Eine exakte Dosierung kann schließlich durch das zwischen den Schneckenförderer 24 und dem Wiegebehälter 28 vorgesehene, elektronisch gesteuerte Absperrventil 25 sichergestellt werden.The screw speed of the screw conveyor 24 is electronically controlled by the weighing device 26 arranged underneath, which has a hemispherical weighing container 28 on an arm 27 which can be rotated through 180 °. Due to the electronically controlled screw transport of the screw conveyor 24, the quantity conveyed by the screw into the hemispherical container 28 is measured via the weighing device and the screw drive is continuously regulated back towards the end of the measuring process. An exact metering can finally be ensured by the electronically controlled shut-off valve 25 provided between the screw conveyor 24 and the weighing container 28.

Die Austrags-, Wiege- und Übergabevorrichtungen 22 der weiteren Abfüllstationen 5 und 6 unterscheiden sich prinzipiell nicht von derjenigen der Abfüllstation 4. Wie in der Fig. 1 dargestellt, können diese beispielsweise eine nur mit einem Schneckenförderer 24 ausgebildete Austragsvorrichtung 23 aufweisen, wobei der kombinierte Austrags-, Wiege- und Übergabevorgang jeweils an die bestimmte zu behandelne Komponente bzw. den Stoff im jeweiligen Aufschüttbehälter angepaßt sein kann.The discharge, weighing and transfer devices 22 of the further filling stations 5 and 6 do not differ in principle from that of the filling station 4. As shown in FIG. 1, these can have, for example, a discharge device 23 designed only with a screw conveyor 24, the combined one Discharge, weighing and transfer process can each be adapted to the specific component to be treated or the substance in the respective dumping container.

In der Fig. 1 sind weiterhin zusätzliche Absaugleitungen 29 zwischen der Austrags-, Wiege- und Übergabevorrichtung 22 und der Absaug- und Filtervorrichtung 11 vorgesehen, um auch diesen Bereich völlig staubfrei durch Absaugung von Staub und Dämpfen zu halten.In FIG. 1, additional suction lines 29 are further provided between the discharge, weighing and transfer device 22 and the suction and filter device 11 in order to keep this area completely dust-free by suction of dust and vapors.

Unterhalb der Austrags-, Wiege- und Übergabevorrichtung 22 ist jeweils ein Einzelbehälter 3 angeordnet, zur Aufnahme des, der jeweiligen Abfüllstation zu entnehmenden Stoffes. Hierfür werden die Behälter 3 manuell oder automatisch mit einem Kunststoffsack 30 beschickt, wobei der obere Rand 31 des Kunststoffsacks 30 über den Behälterrand 32 umgestülpt ist. Wie weiterhin aus Fig. 3 ersichtlich, wird der mit einem Kunststoffsack 30 beschickte Behälter 3 mit einem brillenförmigen Deckel 33 abgedeckt, so daß der äußere Rand 31 des Kunststoffsacks hinter einer Abdeckung geschützt ist und nicht verstauben kann. Die Austrags-, Wiege- und Übergabevorrichtung 22 weist in ihrem unteren Bereich der Übergabevorrichtung 34 einen Anschlußflansch 35 auf, der mit dem brillenförmigen Deckel 33 zusammenwirkt und ein nach außen hin staubfreies Einfüllen des Stoffes aus der Übergabevorrichtung 34 in den Kunststoffsack 30 ermöglicht. Dabei geschieht der Umfüllvorgang durch eine 180°-Drehbewegung des halbkugelförmigen Wiegebehälters 28, so daß das darin enthaltene Gut entleert wird.A single container 3 is arranged below the discharge, weighing and transfer device 22 in order to receive the substance to be removed from the respective filling station. For this purpose, the containers 3 are loaded manually or automatically with a plastic bag 30, the upper edge 31 of the plastic bag 30 being turned over the container edge 32 is. 3, the container 3 loaded with a plastic bag 30 is covered with an eyeglass-shaped cover 33, so that the outer edge 31 of the plastic bag is protected behind a cover and cannot collect dust. The discharge, weighing and transfer device 22 has in its lower region of the transfer device 34 a connecting flange 35 which interacts with the eyeglass-shaped cover 33 and enables the material from the transfer device 34 to be filled into the plastic bag 30 without dust from the outside. The refilling process takes place by a 180 ° rotary movement of the hemispherical weighing container 28, so that the material contained therein is emptied.

Eine Kontrolle für den in dem Behälter 3 eingelegten Kunststoffsack geschieht durch die Lichtschranke 36.The light barrier 36 checks for the plastic bag inserted in the container 3.

Die in der Fig. 1 dargestellten Einzelbehälter 3 werden auf dem linearen Transportband 2 hintereinander geschoben, so daß keinerlei Spiel zwischen den einzelnen Behältern 3 entstehen kann. Dies ist bei einer großen Anzahl von hintereinander geschalteten Abfüllstationen 4 bis 6 zweckmäßig, um eine genaueste und einfache Positionierung der Einzelbehälter unterhalb der jeweiligen Abfüllstation zu erhalten.The individual containers 3 shown in FIG. 1 are pushed one behind the other on the linear conveyor belt 2, so that no play can occur between the individual containers 3. This is expedient in the case of a large number of filling stations 4 to 6 connected in series in order to obtain the most precise and simple positioning of the individual containers below the respective filling station.

Nachdem der Behälter die letzte Abfüllstation 6, z. B. Einzelstation 44 oder eine davor geschaltete letzte Station passiert hat, wird er einer speziellen, in Fig. 4a - d dargestellten stationären Schweißstation 37 zugeführt. In dieser oder kurz vor dieser Schweißstation 37 wird der brillenförmige Deckel 33 seitlich weggeklappt und eine gesonderte Sackrandansaugvorrichtung 38 über den Behälterrand 32 gestülpt. Die Sackrandansaugevorrichtung 38 weist einen geschlitzten Ringkanal 39 auf, in welchen der obere Rand 31 des Kunststoffsacks 30 durch Unterdruck hineingesaugt wird (Rand 31'). Dabei wird der obere Sackrand 31 von zwei gegenüberliegenden durch die seitlichen Schlitze ragenden Greifern 40, 40' erfaßt und seitlich auseinandergezogen (siehe Fig. 4c), so daß der obere Rand 31' des Kunststoffsacks 30 flach zu liegen kommt (siehe Fig. 4d). Eine Kunststoff-Schweißeinrichtung 41 kann dann den oberen Sackrand 31 dicht zusammenschweißen, nachdem die Ausgangsvorrichtung 38 nach oben hin weggezogen ist. Um diesen Schweißvorgang völlig zuverlässig durchführen zu können, muß der obere Rand 31 des Kunststoffsackes 30 völlig staubfrei gehalten werden, wozu der brillenförmige Deckel 33 während des Abfüllvorgangs dient.After the container the last filling station 6, z. B. passed single station 44 or a preceding station, it is fed to a special stationary welding station 37 shown in FIGS. 4a-d. In this or shortly before this welding station 37, the eyeglass-shaped lid 33 is folded away to the side and a separate sack rim suction device 38 is placed over the rim 32 of the container. The sack edge suction device 38 has a slotted annular channel 39, in which the upper edge 31 of the plastic bag 30 is sucked in by negative pressure (edge 31 '). The upper edge of the bag 31 is gripped by two opposite grippers 40, 40 'projecting through the lateral slots and pulled apart laterally (see FIG. 4c), so that the upper edge 31' of the plastic bag 30 comes to lie flat (see FIG. 4d) . A plastic welding device 41 can then weld the upper edge of the bag 31 tightly together after the starting device 38 has been pulled upwards. In order to be able to carry out this welding process completely reliably, the upper edge 31 of the plastic bag 30 must be kept completely dust-free, for which purpose the eyeglass-shaped lid 33 is used during the filling process.

Der Schweißstation 37 folgt eine Abwurfstation 42 für die abgefüllten Kunststoffsäcke 30. Hierzu ist der Behälter 3 in seinem unteren Bereich mit einer schwenkbaren Klappe 43 ausgerüstet, wobei die Klappe 43 mittels einer Kurvensteuerung 44 sanft und allmählich derart geöffnet wird, daß der Sack 30 nicht schlagartig auf die unterhalb der Abwurfstation 42 angeordneten Kontroll-Wiegestation 45 gelangt. Durch die Kontroll-Wiegestation 45 wird das genaue Gesamtgewicht der abgefüllten Einzelkomponenten nochmals kontrolliert und Fehlchargen ggf. aussortiert. Das abgewogene Endprodukt gelangt dann auf ein Förderband 46 zum Weitertransport.The welding station 37 is followed by a discharge station 42 for the filled plastic bags 30. For this purpose, the container 3 is equipped in its lower region with a pivotable flap 43, the flap 43 being opened gently and gradually by means of a cam control 44 in such a way that the sack 30 does not suddenly arrives at the control weighing station 45 arranged below the discharge station 42. The exact total weight of the filled individual components is checked again by the control weighing station 45 and faulty batches are sorted out if necessary. The weighed end product then arrives on a conveyor belt 46 for further transport.

Der in der Abwurfstation 42 entleerte Behälter wird auf dem Transportband 2 weiter transportiert, wobei eine Kurvensteuerung 47 oder eine gleichwirkende Mechanik zur Schließung der schwenkbaren Klappe 43 führt.The container emptied in the discharge station 42 is transported further on the conveyor belt 2, a cam control 47 or an equivalent mechanism leading to the closing of the pivotable flap 43.

Wie in Fig. 2 dargestellt, können die nach der letzten Abfüllstation 6 angeordneten Stationen 37, 42, 45 als zu den Abfüllstationen 4 bis 6 parallel laufende Stationen ausgeführt sein, um die Gesamtlänge der Anlage zu verkürzen. In Fig. 2 ist eine zusätzliche Schwenkstation 48 zum Wegschwenken des brillenförmigen Deckels vor der Schweißstation 37 angedeutet. Weiterhin ist ein Fehlchargenband 49 nach der Kontroll-Wiegestation 45 eingezeichnet, wobei die Fehlchargen aus dem System aussortiert werden. Die leeren Behälter 3 werden in einer Sackfüllstation 50 manuell oder automatisch mit leeren Kunststoffsäcken 30 gefüllt, bevor sie wieder im Kreislauf dem ersten Aufschüttbehälter 7 in der ersten Abfüllstation 4 zugeführt werden. Davor ist noch die Lichtkontrollschranke 26 für die Sackkontrolle vorgesehen.As shown in FIG. 2, the stations 37, 42, 45 arranged after the last filling station 6 can be stations running parallel to the filling stations 4 to 6 be carried out to shorten the total length of the system. An additional swivel station 48 for swiveling the eyeglass-shaped cover away from the welding station 37 is indicated in FIG. 2. Furthermore, a faulty batch belt 49 is drawn in after the control weighing station 45, the faulty batches being sorted out from the system. The empty containers 3 are filled manually or automatically with empty plastic sacks 30 in a sack filling station 50 before they are returned to the first filling container 7 in the first filling station 4 in the circuit. Before that, the light control barrier 26 is still provided for the bag control.

Die Erfindung ist nicht auf das dargestellte und beschriebene Ausführungsbeispiel beschränkt. Sie umfaßt auch vielmehr alle fachmännischen Weiterbildungen ohne eigenen erfinderischen Gehalt. Insbesondere können die Abfüllstationen 4 bis 6 auch auf einem kreisförmigen oder ovalen Ring angeordnet sein, wobei vorzugsweise wiederum die Einzelbehälter 3 auf dem Transportband 2 unter die Abfüllstationen durchgetaktet werden. Die weiteren Bearbeitungsstationen 37, 42, 45 können innerhalb oder außerhalb der Kreis- oder ovalen Transportanordnung liegen.The invention is not restricted to the exemplary embodiment shown and described. Rather, it also encompasses all professional training courses without their own inventive content. In particular, the filling stations 4 to 6 can also be arranged on a circular or oval ring, the individual containers 3 on the conveyor belt 2 again preferably being clocked under the filling stations. The further processing stations 37, 42, 45 can be located inside or outside the circular or oval transport arrangement.

Es wäre auch denkbar, die Transportbehälter 3 stationär und die Abfüllstationen 4 bis 6 sowie die übrigen Stationen zu takten, dies dürfte jedoch nur in speziellen Sonderfällen aufgrund des erhöhten technischen Aufwandes sinnvoll sein.It would also be conceivable to cycle the transport containers 3 in a stationary manner and the filling stations 4 to 6 and the other stations, but this should only make sense in special cases due to the increased technical outlay.
