Abstract
Beschrieben wird ein Seitenfalten- oder Flachsack (200, 201, 212, 214, 217), welcher von einer FFS-Maschine hergestellt und befüllt wurde und welcher zumindest im Bereich zumindest einer der Ecken des Sackes eine Aufreißperforation (207, 208, 216) aufweist. Er ist dadurch gekennzeichnet, dass der Sack im Bereich der zumindest einen Ecke eien Eckabschweißung (206) aufweist.Described is a gusseted or flax bag (200, 201, 212, 214, 217) which has been manufactured and filled by an FFS machine and which has a tear-open perforation (207, 208, 216) at least in the area of at least one of the corners of the sack , It is characterized in that the bag in the region of at least one corner eien Eckabschweißung (206).
Description
Die Erfindung betrifft einen Seitenfaltensack nach dem Oberbegriff des Anspruchs 1, ein Verfahren zur Herstellung und Befüllung eines solchen Seitenfaltensacks und eine entsprechende FFS-Maschine.The The invention relates to a gusseted bag according to the preamble of Claim 1, a method for producing and filling a such gusseted sacks and a corresponding FFS machine.
Die gattungsgemäße Abfüllung von Säcken erfolgt mit den verschiedensten Vorrichtungen. Oft wird der zu befüllende Sack während des Abfüllprozesses von einer Mehrzahl von Greiferzangenpaaren erfasst.The generic filling of bags is done with a variety of devices. Often the bag to be filled while the filling process detected by a plurality of gripper pair.
Eine Untergruppe innerhalb der Abfüllmaschinen bilden die sogenannten FFS-Maschinen. Hierbei steht das Kürzel FFS für Form Fill and Seal, so dass ein besonderes Kennzeichen der Arbeitsweise dieser Maschinen in der Verschweißung der Säcke nach dem Befüllprozess liegt.A Subgroup within the filling machines form the so-called FFS machines. This is the abbreviation FFS for Form Fill and Seal, giving a special feature of the working method of these machines in the welding of the sacks after the filling process lies.
Eine
solche Vorrichtung ist unter anderem aus der
Diese Maschinen eignen sich hervorragend um Säcke schnell und kostengünstig zu bilden und zu befüllen.These Machines are great at bagging fast and inexpensively too form and fill.
Die von FFS-Maschinen hergestellten Säcke werden oft mit rieselfähigem Gut befüllt. Auch aus diesem Grund werden diese Säcke in der Regel nicht mit irgendwelchen Löchern oder Einschnitten versehen. Eine erste Ausnahme bilden Entlüftungsöffnungen, die in der Regel in einen großen Teil der Sackaußenfläche eingebracht sind. Diese Öffnungen werden so gestaltet, dass ihr Durchmesser nicht mehr als einen mm beträgt, um ein Ausrieseln von Füllgut zu vermeiden. Für besonders feine Füllgüter sind mittlerweile sogenannte Mikroperforationen entwickelt worden, die Entlüftungslöcher mit Durchmessern aufweisen, die kleiner als 0,2 mm sind.The Sacks produced by FFS machines often become free-flowing filled. Also for this reason, these bags are usually not with any holes or cuts. A first exception are vents, which usually turns into a big one Part of the bag outer surface introduced are. These openings are designed so that their diameter does not exceed one mm is, to trickle out of contents to avoid. For are particularly fine products Meanwhile, so-called microperforations have been developed, which Vent holes with Have diameters smaller than 0.2 mm.
In jüngster Zeit hat sich die Notwendigkeit ergeben, diese Säcke mit einer Aufreißperforation zu versehen. In diesem Zusammenhang wird unter Aufreißperforation eine Perforation aus Einschnitten oder Einstanzungen verstanden. In der Regel sind diese Einschnitte oder Einstanzungen länger beziehungsweise größer als die beschriebenen Entlüftungslöcher. So haben sich Einschnittlängen von 2 bis 10 mm bewährt. Bevorzugt werden jedoch Einschnittlängen von 4 bis 7 mm. In der Sprache dieser Druckschrift ist auch ein einzelner Schnitt oder eine einzelne Stanzung, welche dem späteren Aufreißen des Sackes dient, eine Perforation. Ein solcher Schnitt ist dann bevorzugt am Rand des Sackes in das Folienmaterial einzubringen und weist in der Regel eine Länge auf, die noch über der bevorzugten Länge der oben angesprochenen Perforationsschnitte liegt. Eine Aufreißperforation dient der Vereinfachung des Aufreißens der Sackhülle. Ein Aufreißen der Sackhülle im Sinne dieser Druckschrift kann auch mit dem Abreißen von Teilen der Sackhülle, wie von Teilen der Boden- oder Kopfnaht – einhergehen.In recently, Time has given rise to the necessity of these bags with a tear perforation to provide. In this context, under tear perforation a perforation of incisions or punctures understood. As a rule, these cuts or punctures are longer or greater than the described vent holes. So have incision lengths proven from 2 to 10 mm. However, incision lengths of 4 to 7 mm are preferred. In the Language of this pamphlet is also a single cut or a single punching, which the later tearing of the Sackes serves, a perforation. Such a cut is then preferred bring in the edge of the bag in the film material and points in usually a length on, that's still over the preferred length the above-mentioned perforation cuts. A tear-open perforation serves to simplify the tearing open of the bag. One Rip the sackcloth For the purposes of this document can also with the tearing off Parts of the bag, as part of the bottom or top seam - go along.
Zur Herstellung und zur Befüllung der bisher bekannten Säcke mit Abreißperforationen im FFS-Verfahren werden die Folienschläuche, aus denen die betreffende FFS-Maschine die Säcke bildet, von einer nicht der FFS-Maschine zugeordneten Perforationseinrichtung perforiert, bevor die Schläuche wieder aufgewickelt und dieser Schlauchwickel der FFS-Maschine zugeführt werden.to Production and filling the previously known sacks with tear-off perforations in the FFS process are the film tubes that make up the relevant FFS machine the sacks makes, not one of the FFS engine perforation device perforated before the hoses again wound up and this hose wrap the FFS machine supplied.
Bei der Verwendung dieser Säcke hat sich jedoch gezeigt, dass gerade die Aufreißperforation eine Schwachstelle bildet, durch die Füllgut rieselt. Diesen Nachteil nimmt man bisher in Kauf oder verzichtet ganz auf eine derartige Perforation von Säcken für rieselförmiges Gut.at the use of these bags However, it has been shown that the tear perforation is a weak point forms, through the contents trickles. This disadvantage is so far in purchase or omitted entirely on such a perforation of sacks for gullies.
Die Aufgabe der vorliegenden Erfindung ist es daher, einen Flach- oder Seitenfaltensack,
- – welcher von einer FFS-Maschine hergestellt und befüllt wurde und
- – welcher leicht aufreißbar ist und
- – welcher sich durch geringere Rieselverluste auszeichnet,
- - which was manufactured and filled by an FFS machine and
- - which is easily breakable and
- - which is characterized by lower trickle losses,
Die vorliegende Erfindung geht von den geschilderten im FFS-Verfahren hergestellten und befüllten Seitenfaltensäcken aus und löst diese Aufgabe dadurch, dass der Sack im Bereich zumindest einer Ecke eine Eckabschweißung aufweist.The present invention is based on the described produced and filled in the FFS process Gusseted sacks and solves this problem in that the bag in the area of at least one corner has a Eckabschweißung.
Durch die erfindungsgemäße Maßnahme kann kein Befüllgut durch die Perforationsschnitte rieseln, die zwischen der Sackkante und der Eckabschweißung angeordnet sind. Die erfindungsgemäße Maßnahme eignet sich – wie dem Anspruch 1 zu entnehmen ist – in gleicher Weise für Flachsäcke.By the measure according to the invention can no filling material trickle through the perforation cuts between the sack edge and the corner weld are arranged. The measure according to the invention is suitable - like the Claim 1 is apparent - in same way for Flat sacks.
Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor.Further embodiments The invention will become apparent from the description and the claims.
