Abstract

Described is a transport container (1) made of textile fabric, the container walls (7, 8, 9, 10) being made from at least one strip of fabric (7, 8, 9, 10) and having at least one longitudinal seam (11, 12). The container is characterized in that the single longitudinal seam (21) or the several longitudinal seams (11, 12) are flush-sewn. The flush-sewn seams (11, 12, 21) are preferably produced using chain stitches.

Description

Die Erfindung betrifft einen flexiblen Behälter aus Textilgewebe, der einen Mantel aus wenigstens einer Gewebebahn aufweist, der mit wenigstens einer Längsnaht versehen ist, wobei die Längsnaht oder die Längsnähte (11, 21) flachgenäht sind (siehe zum Beispiel EP-A-0 140 346).The invention relates to a flexible container made of textile fabric, which has a jacket made of at least one fabric web, which is provided with at least one longitudinal seam, the longitudinal seam or the longitudinal seams (11, 21) being flat-sewn (see for example EP-A-0 140 346 ).

Derartige Transportbehälter aus Textilgewebe sind bekannt und dienen dazu, großvolumige Lasten aufzunehmen, die Gewichte bis zu mehreren Tonnen aufweisen können. In der Fachsprache sind sie unter der Bezeichnung "big bag" oder "FIBC" (für Flexible Intermediate Bulk Container) bekannt.Such transport containers made of textile fabric are known and serve to accommodate large-volume loads that can have weights of up to several tons. In technical terms, they are known as "big bag" or "FIBC" (for flexible intermediate bulk containers).

Die bisher bekannt gewordenen FIBC bestehen zumeist aus einem Mantel, der vier aneinander genähten Mantelflächen umfaßt, und aus einem Boden und einem Deckel, die ebenfalls aus Textilgewebe bestehen. Die einzelnen Textilbahnen sind an den Kanten in herkömmlicher Weise vernäht, wobei jeweils die zwei aneinanderstoßenden Textilbahnen übereinandergelegt und an den doppelten Kanten, gegebenenfalls auch übereinandergeschlagen, mit herkömmlichen Nähmaschinen unter Bildung einer Kantennaht per Kettenstichnaht vernäht werden.The previously known FIBC mostly consist of a jacket which comprises four jacket surfaces sewn together, and a bottom and a lid, which also consist of textile fabric. The individual textile webs are sewn on the edges in a conventional manner, the two abutting textile webs being placed one on top of the other and sewn on the double edges, if necessary also overlapped, with conventional sewing machines to form an edge seam by chain stitching.

Derartige FIBC sollen zum einen in der Herstellung möglichst billig und einfach sein, andererseits aber den geforderten statischen Anforderungen entsprechen.Die Gewebestärke soll aus Kosten-, Gewichts- und Lagergründen möglichst niedrig liegen. Für manche Güter ist es weiters notwendig, den FIBC innen mit einer beschichteten Oberfläche zu versehen. So kann z.B. ein FIBC für eine Last von 1.500 kg aus einem Gewebe mit 200 g/m² bestehen.On the one hand, such FIBCs should be as cheap and simple as possible to manufacture, but on the other hand they should meet the required static requirements. For some goods it is also necessary to provide the FIBC with a coated surface on the inside. For example, a FIBC for a load of 1,500 kg consists of a fabric with 200 g / m².

Die Schwachstellen der FIBC liegen in den Nähten. Für bestimmte Verwendungszwecke ist es erforderlich, daß die FIBC auch bei Falltests dicht bleiben und nicht aufplatzen. Ein solcher Falltest kann z.B. bei voller Ladung durch Abwerfen aus 1,20 m Höhe gegeben sein. Herkömmliche Nähte reißen auf, sodaß das Gut austritt.The weak points of the FIBC are in the seams. For certain purposes, it is necessary that the FIBC remain leakproof even during drop tests and do not burst open. Such a drop test can be given, for example, with a full load by being dropped from a height of 1.2 m. Conventional seams tear open so that the goods come out.

Eine bekannte Lösungsmöglichkeit für dieses Problem liegt darin, ein stärkeres Gewebe zu verwenden. Dies erhöht allerdings die Kosten und erschwert die Verarbeitung des Gewebes, wobei die Festigkeit stets mangelhaft bleibt.A known solution to this problem is to use a stronger fabric. However, this increases the costs and complicates the processing of the fabric, while the strength always remains poor.

Eine weitere Lösungsmöglichkeit liegt darin, den Mantel aus einem Rundgewebe anzufertigen, sodaß er in Längsrichtung überhaupt keine Naht aufweist. Dies bringt jedoch den Nachteil mit sich, daß Rundgewebe nur in beschränkten Dimensionen möglich und erhältlich sind. Die Anfertigung verschiedener Dimensionen für FIBC je nach Kundenwunsch in kleineren Mengen ist praktisch unmöglich. Weiters ist es sehr schwierig und teuer, derartige Mäntel aus Rundgewebe von Innen zu beschichten. Überdies sind Rundsäcke schwierig zu bedrucken.Another solution is to make the jacket from a round fabric so that it has no seam at all in the longitudinal direction. However, this has the disadvantage that round fabrics are only possible and available in limited dimensions. It is practically impossible to produce different dimensions for FIBC in smaller quantities depending on customer requirements. Furthermore, it is very difficult and expensive to coat such coats made of round fabric from the inside. In addition, circular bags are difficult to print on.

Gemäß gegenständlicher Erfindung ist der FIBC dadurch gekennzeichnet, daß die Flachnähte in ihrer gesamten Länge durch ein oder mehrere Kettenstichnähte gebildet sind. Weitere Merkmale sind den Zeichnungen und der nachfolgenden Beschreibung sowie den Patentansprüchen zu entnehmen.According to the present invention, the FIBC is characterized in that the flat seams are formed over their entire length by one or more chain stitch seams. Further features can be found in the drawings and the description below and in the patent claims.

Fig.1 zeigt einen herkömmlichen FIBC mit üblichen Nähten zur Bildung der Längsnähte. Fig.2 zeigt einen Querschnitt durch den Nahtbereich des Mantels. Fig.3 zeigt im Querschnitt einen erfindungsgemäßen FIBC gemäß der Linie III-III in Fig.4 und Fig.4 in auseinandergezogener Stellung die einzelnen Teile eines kompletten erfindungsgemäßen FIBC. Fig.5 zeigt die Schrägansicht eines weiteren Ausführungsbeispiels.1 shows a conventional FIBC with conventional seams for forming the longitudinal seams. 2 shows a cross section through the seam region of the jacket. 3 shows in cross section an FIBC according to the invention along the line III-III in FIG. 4 and FIG. 4 in an exploded position, the individual parts of a complete FIBC according to the invention. 5 shows the oblique view of a further exemplary embodiment.

Der bekannte FIBC gemäß Fig.1 weist einen Mantel 1 aus vier Mantelflächen 2 auf, die aus einzelnen Gewebebahnen bestehen. Die Längsnähte 3 sind fahnenartig ausgebildet, wie dies in Fig.2 im Querschnitt näher dargestellt ist. Von den beiden Mantelflächen 2 stehen Fahnen 4 nach außen, die durch jeweils eine Naht 3 aus ein oder mehreren Einzelnähten 5 vernäht sind. An den fahnenartig ausgebildeten Nähten 3 sind oben Halteschlaufen 12 angenäht, die dazu dienen, den FIBC zu heben und zu transportieren. In Fig.1 sind nur drei der üblicherweise vier vorgesehenen Halteschlaufen eingezeichnet.The known FIBC according to FIG. 1 has a jacket 1 consisting of four jacket surfaces 2, which consist of individual fabric webs. The longitudinal seams 3 are flag-like, as shown in more detail in cross-section in FIG. From the two lateral surfaces 2 there are flags 4 which are sewn by a seam 3 from one or more individual seams 5. Holding straps 12 are sewn onto the flag-shaped seams 3, which serve to lift and transport the FIBC. In Figure 1, only three of the usually four holding straps are shown.

Oben und unten ist der FIBC durch einen Deckel 13 und einen Boden 15 mit Einfüllstutzen 14 und Auslaufstutzen 16 verschlossen.The FIBC is closed at the top and bottom by a cover 13 and a base 15 with filler neck 14 and outlet neck 16.

Bei starker Belastung, wie z.B. bei dem eingangs beschriebenen Falltest, entsteht durch das Füllgut ein starker Druck in Richtung der Pfeile 6 (siehe Fig.2) und es kommt dabei zu einem Aufreißen der Einzelnähte 5 bzw. aller Nähte 3. Das Aufreißen ist bei dieser Nahtart dadurch begünstigt, daß die Mantelflächen 2 auseinandergezogen werden und dabei immer nur die innenliegende Einzelnaht 5 belastet wird, sodaß der Reihe nach alle Einzelnähte gesprengt und die gesamte Naht 3 geöffnet wird.With heavy loads, such as In the drop test described at the beginning, the filling material creates a strong pressure in the direction of the arrows 6 (see FIG. 2) and the individual seams 5 or all seams 3 are torn open. The tearing open is favored in this type of seam in that the lateral surfaces 2 are pulled apart and only the inner individual seam 5 is loaded, so that all the individual seams are blown in sequence and the entire seam 3 is opened.

In Fig.3 ist der erfindungsgemäße FIBC dargestellt, der flachgenäht ist. Die Bahnen werden dabei überlappend aufeinandergelegt und mittels "arm-abwärts-Nähen" vernäht. Dazu ist eine besondere Nähmaschinenkonstruktion notwendig, die es erlaubt, auf diese Weise große Stoffbahnen flach mit Kettenstichnaht zu nähen.3 shows the FIBC according to the invention, which is flat-sewn. The panels are overlapped and sewn using "arm down sewing". This requires a special sewing machine design that allows large pieces of fabric to be sewn flat with chain stitch.

In Fig.3 sind somit die flachen Bahnstücke 7, 8, 9, 10 an den überlappenden Stellen mit den Nähten 11 vernäht, die ebenfalls aus mehreren Einzelnähten gebildet sein können.In Figure 3, the flat web pieces 7, 8, 9, 10 are sewn at the overlapping points with the seams 11, which can also be formed from several individual seams.

Die notwendigen Halteschlaufen 12 können dabei leicht mitgenäht werden.The necessary straps 12 can be easily sewn.

In Fig.3 sind zusätzlich noch die üblichen anderen Teile dargestellt, nämlich der Deckel 13 mit dem Einfüllstutzen 14 und der Boden 15 mit dem Auslaufstutzen 16. Der Boden 15 und der Deckel 13 können auch bei großen Belastungen mit dem Mantel 1 auf herkömmliche Weise vernäht werden, da diese Nähte nicht so stark beansprucht werden, wie die Längsnähte 11.In Figure 3, the usual other parts are also shown, namely the lid 13 with the filler neck 14 and the bottom 15 with the outlet neck 16. The bottom 15 and the lid 13 can be sewn to the jacket 1 in a conventional manner even under heavy loads because these seams are not subject to as much stress as the longitudinal seams 11.

Die Teile 13 bis 16 sind üblicherweise ebenfalls aus Textilgewebe hergestellt. Die Stutzen 14 und 16 können mit den Bändern 17, 18 abgebunden werden.The parts 13 to 16 are usually also made of textile fabric. The sockets 14 and 16 can be tied with the bands 17, 18.

Ein bevorzugtes Merkmal der Nahtausbildung liegt auch darin, daß eine Kettenstichnaht ermöglicht ist. Für diese Nahtausbildung ist ein billiges Nähgarn verwendbar und für den Unterfaden können große Spulen vorgesehen werden. Dies ist ein erheblicher Vorteil gegenüber dem bisher für Flachnahten bei Zeltplanen verwendeten Steppstich, der ein teures Garn erfordert und dessen Unterfaden in relativ kleinen Schiffchen untergebracht werden muß, die laufend zu wechseln sind.A preferred feature of seam formation is that a chain stitch seam is made possible. A cheap sewing thread can be used for this seam formation and large bobbins can be provided for the lower thread. This is a considerable advantage over the lockstitch previously used for flat seams in tarpaulins, which requires an expensive thread and whose lower thread has to be accommodated in relatively small boats, which have to be changed continuously.

Bei dem erfindungsgemäßen FIBC bilden die Nähte eine durchgehende Verstärkungsbahn im Mantel. Die Tragegurte oder Schlaufen 12 können somit an diesen Nahtbereichen einfach angenäht oder mitgenäht werden. Extra Verstärkungsgurte sind zumeist nicht notwendig.In the FIBC according to the invention, the seams form a continuous reinforcement path in the jacket. The carrying straps or loops 12 can thus simply be sewn or sewn onto these seam areas. Extra reinforcement straps are usually not necessary.

Die einzelnen flachen Bahnen können vor dem Vernähen leicht bedruckt werden und auf der Innenseite ist mit herkömmlichen Beschichtungsmaschinen das Beschichten möglich. Zufolge der reißfesten Ausbildung der Naht kann ein Gewebe mit relativ geringem Flächengewicht verwendet werden, wie es die Reißfestigkeit des Gewebes erlaubt.The individual flat webs can be easily printed before sewing and coating is possible on the inside with conventional coating machines. Due to the tear-resistant design of the seam, a fabric with a relatively low basis weight can be used, as the tensile strength of the fabric allows.

Bei der in Richtung der Pfeile 19, 20 in Fig.3 auftretenden Zugbeanspruchung werden alle Einzelnähte der jeweiligen Naht gleichmäßig auf Zug beansprucht, sodaß die Einzelnähte zugleich halten und die Belastung des Gewebes im Nahtbereich wesentlich besser verteilt ist.With the tensile stress occurring in the direction of arrows 19, 20 in FIG. 3, all the individual seams of the respective seam are subjected to tensile stress evenly, so that the individual seams hold at the same time and the load on the fabric in the seam region is distributed much better.

Fig.5 zeigt ein weiteres Ausführungsbeispiel des erfindungsgemäßen Behältes in Form eines sogenannten "Einpunktsackes". Der Mantel 1 besteht aus einer einzigen Gewebebahn, die entlang einer einzigen Naht 21 flachgenäht ist. Nach oben hin ist die Gewebebahn von zwei Seiten her zusammengefaßt und bildet eine einzige Tragschlaufe 22, an der das volle Gewicht des gefüllten Behälters hängen kann. Der Boden 23 kann mit üblicher Kantennaht mit dem Mantel 1 verbunden sein. Mit 24 ist eine angenähte Tasche für Dokumente bezeichnet. Durch die Schlitze 25 kann der Behälter befüllt werden. Die Bänder 26 dienen zum Verschließen.5 shows a further embodiment of the container according to the invention in the form of a so-called "single-point sack". The jacket 1 consists of a single fabric web that is flat-stitched along a single seam 21. At the top, the fabric web is combined from two sides and forms a single carrying loop 22, on which the full weight of the filled container can hang. The bottom 23 can be connected to the casing 1 with a conventional edge seam. A sewn-on pocket for documents is designated by 24. The container can be filled through the slots 25. The bands 26 are used for closing.

Dieser big bag mit nur einer Naht weist die Festigkeit eines Behälters aus Rundgewebe auf, ohne dessen Nachteile zu haben. So ist insbesondere die Ver- und Bearbeitung des Gewebes, wie z.B. das Beschichten, bei einer Flachbahn wesentlich einfacher.This big bag with only one seam has the strength of a container made of round fabric without having its disadvantages. In particular, the processing and processing of the fabric, such as coating, much easier with a flat web.

Die Naht 21 kann auch an anderer als der eingezeichneten Stelle liegen, z.B. auf der Seite, auf der sich die Gewebebahn zur Tragschlaufe 22 hin erstreckt. Die Naht 21 erstreckt sich in diesem Fall bevorzugt ebenfalls bis zur Tragschlaufe. Weiters können auch mehr Nähte vorgesehen sein, wie z.B. zwei Nähte an gegenüberliegenden Seiten des Einpunktsackes.The seam 21 can also lie at a different location from the one shown, e.g. on the side on which the fabric web extends to the carrying loop 22. In this case, the seam 21 preferably also extends up to the carrying loop. Furthermore, more seams can be provided, e.g. two seams on opposite sides of the single-point sack.
