Abstract

In a process for welding laminates with several layers formed into bags and filled with highly viscous or plaste-like materials contg. organic solvents, the material placed in direct contact with the filling material is a sheet of polyalkylene and the sheet next to it is a sheet of polyamide. Pref. the outside layer of the bag is further protected with a sheet of metal, particularly Al and finally a sheet of cellulose based material e.g. regenerated cellulose. Welding may be ultrasonic, or by high frequency or low temp. thermo-electric heating. The welded packages formed from the laminates are impermeable so that solvents may be retained.

Description

"Verpackungsverfahren für hochviskose, organische Lösungsmittel enthaltende Massen" Die Erfindung bezieht sich auf ein Verpackungsverfahren für hochviskose, pastöse, organische Lösungsmittel enthaltende Massen unter Verwendung einer Förder- und Portionierungsanlage."Packaging process for highly viscous organic solvents Masses "The invention relates to a packaging method for highly viscous, pasty masses containing organic solvents using a conveyor and portioning system.

Das Verpacken hochviskoser, pastöser, organische Lösungsmittel enthaltenden Massen stellt in der Praxis heute ein großes Problem dar, da aufgrund der organischen Lösungsmittel ein normales Schweißverfahren nicht durchgeführt werden kann, andererseits auch die bisher üblichen Folien nicht diffusionssicher sind und damit nicht die Haltbarkeit der verpackten Massen garantieren.The packaging of highly viscous, pasty, organic solvents In practice, masses are a major problem today because of the organic Solvent a normal welding process cannot be carried out, on the other hand also the foils customary up to now are not diffusion-proof and thus not the Guarantee the shelf life of the packaged masses.

Bisher wurden hochviskose, pastöse, organische Lösungsmittel enthaltende Massen, wie beispielsweise Spachtelmassen, in der Lackindustrie nur in Metallbehälter, Dosen oder Blechtrommeln abgepackt. Dieses Verpackungsverfahren hatte die Nachteile, daß handelsübliche randlose Blechdosen nicht so dicht schließen, daß kein Gasaustausch erfolgen konnte, so daß also auch in diesen Verpackungsbehältern eine längere Lagerung der Massen nicht erfolgen konnte. Weiterhin ist der Kostenanteil für die Verpackung gegenüber dem Füllgut so hoch, daß damit die Kosten für das verpackte Gut unangenehm beeinflußt wurden.So far, highly viscous, pasty, organic solvents have been used Compounds, such as fillers, in the paint industry only in metal containers, Packed cans or tin drums. This packaging method had the disadvantages that commercially available rimless tin cans do not close so tightly that there is no gas exchange could take place, so that longer storage in these packaging containers the masses could not take place. Furthermore, the cost share is for the packaging so high compared to the contents that the costs for the packaged good are unpleasant were influenced.

Der Erfindung liegt die Aufgabe zugrunde, eine Möglichkeit zu schaffen, hochviskose oder pastöse, organische Lösungsmittel enthaltende Massen so kostengünstig zu verpacken, daß damit das Füllgut nicht durch die Kosten für die Verpackung unwirtschaftlich beeinflußt wird, andererseits das Füllgut aber auch Uber längere Zeit gelagert werden kann, ohne daß durch Entweichen oder Diffundieren der organischen Lösungsmittel ein Unbrauchbarwerden des Füllgutes eintritt.The invention is based on the object of creating a possibility highly viscous or pasty compositions containing organic solvents so inexpensively to pack so that the product is not uneconomical due to the cost of packaging is influenced, but on the other hand the contents can also be stored for a longer period of time can without escape or diffusion of the organic solvents the contents become unusable.

Das der Erfindung zugrundeliegende Ziel wird dadurch gelöst, daß ein Verpackungsverfahren eingesetzt wird, das dadurch gekennzeichnet ist, daß sich an die Portionierungsanlage eine Verpackungsvorrichtung anschließt, in der eine aus mindestens einer Folienbahn bestehende Kunststoff-Verbundfolie zu einem Schlauch geformt, gefüllt und in verschlossene Einzelbeutel getrennt wird, wobei die eine Folie der Verbundfolie aufgrund ihrer chemischen Eigenschaften gegenüber dem Füllgut diffusionsdicht, die andere Folie aufgrund ihrer chemischen Eigenschaften aber gut verschweißbar ist.The object underlying the invention is achieved in that a Packaging method is used, which is characterized in that on the portioning system connects to a packaging device in which a at least an existing plastic composite film to a film web is formed into a tube, filled and separated into closed individual bags, the one film being compared to the composite film due to its chemical properties diffusion-proof to the filling material, the other film due to its chemical properties but is easy to weld.

Gemäß der Erfindung wird weiterhin so vorgegangen, daß die gut verschweißbare Folie durch eine Schweißanlage verschweißt wird, die mit einem die Schweißtemperatur erbringenden ~flüssigen oder gasförmigen Medium betrieben wird.According to the invention, the procedure is further that the easily weldable Foil is welded by a welding system, which with one the welding temperature supplying ~ liquid or gaseous medium is operated.

Durch diese Verfahrensmerkmale wird erreicht, daß auf der einen Seite eine Folie eingesetzt wird, die gegenüber dem Füllgut im wesentlichen diffusionsdicht, andererseits aber gut verschweißbar ist, so daß die Folie auch bei relativ niedrigen Temperaturen verschweißt werden kann. Durch die Anwendung niedriger Schweißtemperaturen wird auch bei organische Lösungsmittel enthaltenden Massen, die also explosionsgefährlich sind, ein Verschweißen von Kunststoffolien möglich gemacht, was bisher nicht möglich war, andererseits wird aber gleichzeitig erreicht, daß, trotzdem eine verschweißbare Kunststoffolie eingesetzt wird, der schließlich erzielte Packungsbeutel im wesentlichen diffusionsdicht das FA gut umschließt.These process features achieve that on the one hand a film is used that is essentially diffusion-tight with respect to the filling material, on the other hand, however, it is easy to weld, so that the film even at relatively low Temperatures can be welded. By using low welding temperatures is also explosive in the case of masses containing organic solvents are made a welding of plastic films possible, which was previously not possible was, on the other hand, it is achieved at the same time that, nevertheless, a weldable Plastic film is used, the packing bag finally achieved essentially well encloses the FA in a diffusion-tight manner.

I voraufgehenden wurde von einer Förderanlage und einer Portionierungsanlage gesprochen. Beide Anlagen gehören in ihrem grundsätzlichen Aufbau zum Stand der Technik und können in unterschiedlichster Weise ausgebildet sein, ohne daß dadurch das eigentliche Verpackungsverfahren erfindungswesentlich beeinflußt wird.I was preceded by a conveyor system and a portioning system spoken. Both plants belong in hers basic structure to the state of the art and can be designed in a wide variety of ways, without thereby affecting the actual packaging process essential to the invention will.

Ein Ausfuhrungsbeispiel einer zur Durchführung des Verfahrens geeigneten Vorrichtung ist in der nachfolgenden Beschreibung anhand der Zeichnung erläutert. In der Zeichnung zeigt: Fig. 1 den Gesamtaufbau der Anlage und Fig. 2 in größerem Maßstab eine Ansicht der eigentlichen Schweißanlage und beutelbildenden Vorrichtung.An exemplary embodiment of a suitable for carrying out the method The device is explained in the following description with reference to the drawing. The drawing shows: FIG. 1 the overall structure of the system and FIG. 2 in a larger scale Scale a view of the actual welding system and the bag-forming device.

In Fig. 1 ist mit 1 eine sogenannte Förderanlage für hochviskose und pastöse Massen dargestellt, die beispielsweise aus einem die zu verpackende Masse enthaltenden Vorratsbehälter 2 besteht. Auf diesen Vorratsbehälter wird nach Abnahme des Deckels eine Druckplatte aufgesetzt, die durch die beiden-Druckstempel 3 und 4 nach unten in den BehAlter gepreßt wird, aber eine Ausfaßöffnung aufweist, durch die die unter Druck gesetzte Masse nunmehr ausfließen kann, so daß diese Masse durch einen Führungsschlauch 5 zur eigentlichen Portionierungsanlage 6 gelangen kann.In Fig. 1, 1 is a so-called conveyor system for highly viscous and Pasty masses shown, for example from a mass to be packaged containing reservoir 2 consists. This storage container is used after acceptance of the lid, a pressure plate is placed, which by the two-plunger 3 and 4 is pressed down into the container, but has a discharge opening through which the pressurized mass can now flow out, so that this mass through a guide hose 5 can reach the actual portioning system 6.

Die Portionierungsanlage kann in an sich bekannter Weise ausgebildet sein und bei dem dargestellten Ausführungsbeispiel sind zwei gegenläufig arbeitende Druckzylinder 7 und 8 vorgesehen, die nacheinander die Portionierung der durch den Schlauch 5 zugeführten Masse vornehmen und diese derart portionierte Masse durch ein Führungs- und Füllrohr 9 den eigentlichen Beuteln zuführen.The portioning system can be designed in a manner known per se and are in the illustrated embodiment two in opposite directions working pressure cylinders 7 and 8 are provided, the portioning one after the other make the mass supplied through the tube 5 and portion it in this way Feed mass through a guide and filling tube 9 to the actual bags.

Die eigentliche Verpackungsmaschine ist in größerem Maßstab in Fig. 2 dargestellt. Eine als Verbundfolie gemäß der Erfindung ausgebildete Folienbahn ist auf einer Vorratsrolle lo aufgerollt und wird um das Füllrohr 9 zu einem Schlauch geformt, der bei 11 erkennbar ist. Dieser Schlauch wird an seiner offenen Längskante durch die Schweißvorrichtung 12 verschlossen, wobei hier auch eine andere an sich bekannte, aber einen dichten Verschluß gewährleistende Verschlußvorrichtung eingesetzt werden kann. In den derart gebildeten Schlauch reicht das untere Ende des Füllrohres 9 ein und die durch das Füllrohr zugeführte Masse fließt nun unter Druck in den gebildeten Schlauch ein. Gleichzeitig ist eine Schweißanlage 13 vorgesehen, die bei dem dargestellten Ausfthrungsbeispiel als eine durch ein die Schweißtemperatur erbringendes, flüssiges oder gasförmiges Medium betriebene Schweißanlage ausgebildet ist. Durch diese Schweißanlage wird eine Verschweißung des Schlauches quer zu seiner Längsachse durchgeführt, wobei die derart erzielte einfache oder doppelt ausgebildete Schweißnaht den Boden des zu füllenden Beutels bildet, gleichzeitig aber auch den Verschluß des gefüllten Beutels schafft. The actual packaging machine is shown on a larger scale in Fig. 2 shown. A film web designed as a composite film according to the invention is rolled up on a supply roll lo and becomes a hose around the filling tube 9 shaped, which can be seen at 11. This hose is on its open longitudinal edge closed by the welding device 12, here also a different one per se known, but a tight seal ensuring locking device used can be. The lower end of the filling pipe extends into the hose formed in this way 9 and the mass supplied through the filling tube now flows under pressure into the formed hose. At the same time a welding system 13 is provided which in the illustrated embodiment as one through the welding temperature producing, liquid or gaseous medium operated welding system formed is. This welding system welds the hose transversely to his Carried out longitudinal axis, the thus achieved single or double trained Weld seam forms the bottom of the bag to be filled, at the same time but also creates the closure of the filled bag.

Wird eine eine doppelte Schweißnaht erzielende Schweißanlage eingesetzt, kann gleichzeitig zwischen den gebildeten zwei Schweißnähten eine Perforations- oder Trennlinie 14 gebildet werden, die das Abtrennen der einzelnen gefüllten Beutel 15 ermöglicht. Die gefüllten Beutel 15 werden über das in Fig. 1 dargestellte Förderband 16 abgefördert.If a welding system that achieves a double weld is used, a perforation can be created between the two weld seams at the same time or dividing line 14 can be formed, which allows the separation of the individual filled bags 15 allows. The filled bags 15 are transported via the conveyor belt shown in FIG. 1 16 promoted.

In der Zeichnung sind die Schweißanlagen 12 und 13 nur eino fach dargestellt, selbstverständlich bestehen entsprechende Gegenhalter oder doppelte Schweißvorrichtungens die aufeinanderzu arbeiten.In the drawing, the welding systems 12 and 13 are shown only once, of course there are corresponding counterholders or double welding devices who work towards each other.

Die für das Fördern der Folie weiterhin erforderlichen Mittel sind in der Zeichnung aus ObersichtlichkeitsgrUnden ebenfalls nicht dargestellt, da diese Mittel an sich bekannt sind und in verschiedenen Verpackungsautomaten bereits Anwendung finden.The funds still required for conveying the film are also not shown in the drawing for reasons of clarity, as these Means are known per se and are already used in various packaging machines Find.

Gemäß der Erfindung besteht die Folienbahn aus einer Verbundfolie, wobei die eine Folie aufgrund ihrer chemischen Eigenschaften gegenüber dem Füllgut im wesentlichen diffusionsdicht, die andere Folie aufgrund ihrer chemischen Eigenschaften gut verschweißbar ist, wobei vorzugsweise'die gut verschweißbare Folie innen in dem gebildeten Schlauch und die diffusionsdichte Folie außen am Schlauch angeordnet ist. Der Einsatz weiterer Folienbahnen, um derart eine noch stärkere Verbundfolie zu schaffen, liegt selbstverständlich im Rahmen der Erfindung.According to the invention, the film web consists of a composite film, one film due to its chemical properties compared to the filling material essentially diffusion-tight, the other film due to its chemical properties can be welded well, preferably the well-weldable film inside the hose formed and the diffusion-proof film arranged on the outside of the hose is. The use of further Foil webs to make such an even stronger one Creating composite film is of course within the scope of the invention.
