Description

Seitenfaltenbeutel mit sich beim Füllen bildendem Boden sowie Verfahren und Vorrichtung zum Herstellen dieses Seitenfältenbeutels Es sind Seitenfaltenbeutel bekannt, bei deneni man durch entsprechende Vorrichtungen die Möglichkeit zu schaffen versucht, daß diese Beutel beim Füllen unter dem Druck des Füllgutes von selbst einen quadratischen oder rechteckigen Boden bilden. Man hat beispielsweise vorgeschlagen, den gesamten Beutel in den späteren Bodenfalzkanten vorzuknicken. Diese Maßnahme hat allerdings den Nachteil, daß es schwer ist, den genauen Abstand von der Bodenfalzkante zu halten. Andererseits besteht aber auch kaum die Möglichkeit, ein einwandfreies, und schnelles Legen des Bodens zu ermöglichen, da sich die Kniffkanten in den, Seitenfalten überdecken und zu Störungen Anlaß:geben. Man hat weiterhin vorgeschlagen, die inneren Ecken. der äußeren Seitenfalten von gefütterten Beuteln mit lose bindendem Klebstoff zu versehen. Diese Ecken sollen sich dann unter dem Druck des Füllgutes legen, wobei dann der Klebstoff abreißt und die Bodenbildung bewirkt.Side gusset bags with a bottom that forms during filling and processes and apparatus for producing this gusseted bag. They are gusseted bags known, in which one can create the possibility by means of appropriate devices tries to make these bags by themselves when they are filled under the pressure of the contents form a square or rectangular floor. It has been suggested, for example, to fold the entire bag in advance in the later bottom fold edges. This measure however, has the disadvantage that it is difficult to determine the exact distance from the bottom rabbet edge to keep. On the other hand, there is hardly any possibility of a flawless, and to enable the floor to be laid quickly, as the creased edges are in the side folds cover up and cause disturbances: give. The internal ones have also been suggested Corners. the outer gussets of lined bags with loosely binding adhesive to provide. These corners should then be placed under the pressure of the product, whereby then the adhesive tears off and causes the bottoming.

Dieses Verfahren ist wohl für mehrwandige und große Seitenfaltbeutel verwendbar, hat aber den Nachteil, daß eine wirklich sichere Bodenbildung bei der automatischen Füllung oder der Füllung von Hand nicht gewährleistet wird. Man hat auch schon vorgeschlagen, den Beutel von außen entsprechend der halben Bodenbreite mit zusätzlichen Kartonstreifen oder Papierstreifen zu verkleben, um dadurch dem Vorbruch und das Aufziehen der Seitenfalten beim Füllen zu- ermöglichen. Dieses Verfahren. .gestattet wohl ein gutes Legen, des Bodens, hat aber den Nachteil, daß zusätzlich Material gebraucht wird und ein weiterer Arbeitsgang erforderlich ist. .This method is probably for multi-walled and large gusseted bags usable, but has the disadvantage that a really safe bottom formation in the automatic filling or filling by hand is not guaranteed. One has also already proposed, the bag from the outside corresponding to half the bottom width to be glued with additional cardboard strips or paper strips, around thereby enabling the pre-opening and opening of the gussets during filling. This method. . Allows a good laying of the soil, but has the disadvantage that additional material is needed and another work step is required is. .

- Nach der Erfindung wird ein Seitenfaltenbeutel mit sich beim Füllen bildendem Boden angestrebt, der mit einfachsten Mitteln beim Füllen des Beutels das sichere Bilden eines quadratischen oder rechteckigen Bodens ,gewährleistet. Zu diesem Zweck besteht die Erfindung darin, daß an der Bodenfalzkante, zweckmäßig dreieckförmig, Klebstoff aufgetragen ist, der die Seitenfaltenflächen im Bereich des späteren Bodens mit den zugehörigen Außenflächen des Beutels verbindet. Wenn ein solcher Seitenfaltenbeutel gefüllt wird, dann werden die die Seitenwand, bildenden Falten nach außen gedrückt, und unter der Wirkung des Fülldruckes legen sich. die dreieckförmigen Enden dieser Seitenfalten an der Bodenfalzkante zwanglos unmittelbar auf die Klebstoffverstärkungen des, sich bildenden Bodens auf. Dieser Seitenfaltenbeutel hat somit zur sicheren Bildung dess Bodens kein zusätzliches Papier- oder Pappmaterial notwendig.- According to the invention, a gusset bag is with you when filling Striving to form the bottom with the simplest means when filling the bag the safe formation of a square or rectangular floor is guaranteed. For this purpose, the invention consists in that at the bottom rebate edge, expedient triangular, adhesive is applied to the gusset areas in the area of the subsequent bottom connects to the associated outer surfaces of the bag. if such a side gusset bag is filled, then the side wall forming The folds are pressed outwards and under the effect of the filling pressure they subside. the triangular ends of these side folds on the bottom fold edge without any constraints on the adhesive reinforcements of the floor that is being formed. This gusseted bag thus has no additional paper or cardboard material for the safe formation of the bottom necessary.

Der Vorteil des Seitenfaltenbeutels nach der Erfindung besteht aber weiterhin darin, daß sich die Herstellung dieses Seitenfaltenbeutels in einfachster Weise durchführen läßt. Gemäß der Erfindung werden auf die von der Rolle kommende Papierbahn an der späteren Bodenfalzkante Klebstoffecken aus heißsiegelfähigem Leim aufgetragen, die nach Fertigstellung des Werkstückes durch: Wärmeeinwirkung zweckmäßig mit Hilfe einer beheizten Walze zum, Verkleben gebracht werden. Als heißsiegelfähiger Leim kommt in erster Linie ein Kunststoffkleber in- Betracht.The advantage of the gusseted bag according to the invention, however, exists furthermore, that the production of this gusseted bag in the simplest Way to perform. According to the invention are on the coming from the role Paper web on the later bottom fold edge glue corners made of heat-sealable glue applied after completion of the workpiece by: Heat exposure appropriate with the help of a heated roller for gluing. As more heat sealable Glue is primarily a plastic adhesive.

Die Vorrichtung zur Durchführung dieses Verfahrens ist somit gemäß der Erfindung .gekennzeichnet durch ein Auftragwerk zur Aufbringung der Klebstoffecken aus heiß-siegelfähigem Leim auf die Papierbahn, und zwar vor der Bildung des mit Seitenfalten versehenen Schlauches und durch eine beheizte Walze, an der der fertige Seitenfaltenbeutel vorbeigeführt wird. -Durch die beheizte Walze wird somit der Klebstoffauftrag zum Verschweißen bzw. Verssiegeln `gebracht. Man erhält somit tatsächlich an. den entscheidenden Ecken des Seitenfaltenbeutels an - der Bodenfalvkante eine Klebstoffverstärkung, die allein dazu ausreicht, um die sichere Bodenbildung des Beutels unter, der Einwirkung des Druckes des Füllgutes zu erreichen.The device for performing this method is thus in accordance with of the invention. characterized by an applicator for applying the adhesive pads of heat-sealable glue on the paper web, before the formation of the with Gusseted hose and through a heated roller on which the finished Gusset bag is passed by. -The heated roller thus becomes the Adhesive application for welding or sealing `brought. So you actually get at. the crucial corners of the gusseted bag - the bottom fold one Adhesive reinforcement which alone is sufficient to ensure that the Bag under the action of the pressure of the contents to reach.

In der Zeichnung ist die Erfindung als, Ausführungsbeispiel verdeutlicht, und zwar zeigt Abb. i eine schematische Seitenansicht einer Seitenfaltenbeutelmaschine mit einem Auftragwerk für heißsiegelfähigen Klebstoff und einer Andruckwalze,.In the drawing, the invention is illustrated as an exemplary embodiment, namely Fig. i shows a schematic side view of a gusset bag machine with an applicator for heat-sealable adhesive and a pressure roller.

Die Papierbahn i wird von: der Rolle ia abgezogen und gelangt in das Klebstoff auftragwerk, welches aus dem Klebs,toffauftragsegment 2 mit Gegendruckrolle 2a, der Schöpfrolle 3 und dem Klebstofftrog 4 .besteht. Auf die noch nicht gefaltete Papierbahn werden also durch das Klebstofkauftragsegment die Klebstoffecken 4a aufgebracht, wie sie in der Abb. 2 verdeutlicht sind. Die Papierbahn, i durchläuft dann eine übliche Leim; vorrichtung, bestehend aus dem Trog 5, der Leimauftragwalze 5a und der Gegendruckrolle 5b, mit deren: Hilfe die Leimung für die spätere Längsnaht des Seitenfaltenbeutels erzielt wird. Anschließend: durchläuft die Papierbahn i eine an sich, bekannte, nicht dargestellte Faltvorrichtung, so daß der bekannte Seitenfaltenschlauch aus dieser Papierbahn entsteht.. Anschließend wird dieser Seitenfaltenpapierschlauch dann durch die Abschneidevorrichtung 6 in einzelne Werkstücke zerlegt, welche über die Fördersegmente 7, 7a, 7b und 8, 8a, 8b dem Bodenlegezylinder 9 zugeführt werden. Mit Hilfe des Falzmessers io wird der Boden i i am dem einzelnen Schlauchabschnitt an der Bodenfalzkante umgelegt, und mit Hilfe der Klebstoffwalze 12, die ihren Leim aus dem Trog 121 entnimmt, wird am unteren Ende des umgefalteten Bodenlappens der nötige Klebstoff aufgetragen.The paper web i is pulled off: the roll ia and enters the Adhesive structure, which consists of the adhesive, material application segment 2 with a counter-pressure roller 2a, the scoop roller 3 and the adhesive trough 4. Exists. On the one that has not yet been folded Paper web the adhesive corners 4a are applied through the adhesive application segment, as shown in Fig. 2. The paper web, i then runs through a usual glue; device consisting of the trough 5, the glue application roller 5a and the counter-pressure roller 5b, with which: The glue for the later longitudinal seam of the Gusseted bag is achieved. Then: the paper web i runs through a per se, known folding device, not shown, so that the known gusseted tube from this paper web is created .. This gusseted paper tube is then made then disassembled by the cutting device 6 into individual workpieces, which over the conveyor segments 7, 7a, 7b and 8, 8a, 8b are fed to the floor-laying cylinder 9. With the help of the folding knife io, the bottom i i on the individual tube section folded over at the bottom rebate edge, and with the help of the glue roller 12 that its glue removed from the trough 121, is at the lower end of the folded bottom flap necessary glue applied.

Alsdann wandert der fertige Seitenfaltenbeutel zwischen dem Bodenlegezylinder 9 und der beheiztem Walze, i3 hindurch. Da in dem Klebstoffauf tragwerk 2, 2a, 3,4 ein heißsiegelfähiger Leim verwendet wurde, erfolgt zwischen dem Bodenlegezylinder 9 und, der 'beheizten Walze 13 eine ,Verschweißung -der Klebstoffecken4a. Diese Klebstoffverstärkungen brauchen nicht unbedingt dreieckförmig zu sein. Man kann auch eine Mehrzahl von Klebstofftupfen anwenden oder aber z. B. auch den Klebstoff streifenförmig auftragen.The finished gusseted bag then moves between the bottom-laying cylinder 9 and the heated roller, i3 through it. Since in the adhesive support structure 2, 2a, 3.4 a heat sealable glue was used is placed between the floor laying cylinder 9 and, of the 'heated roller 13, a welding of the adhesive corners 4a. These Adhesive reinforcements do not necessarily have to be triangular. One can also use a plurality of spots of glue or z. B. also the adhesive Apply in strips.

Der so gefertigte Seitenfaltenbeutel gelangt dann in der üblichen Weise zu dem Stapel W auf dem. Stapeltisch 14.The gusseted bag produced in this way then ends up in the usual Way to the stack W on the. Stacking table 14.
