Abstract
Description
Die Erfindung betrifft einen Beutel aus einer Kunststofffolie, insbesondere Automatenbeutel, mit einer Einfüllöffnung, einer Vorderwand, einer Rückwand und einer im Bereich der Einfüllöffnung, verlängerten Rückwand zur Bildung einer Beutelklappe, wobei die Vorderwand und die Rückwand an ihren Längsseiten, zur Bildung von Seitenwänden und an einer der Einfüllöffnung entgegen gesetzten Querseite, zur Bildung einer Bodennaht, miteinander verschweißt sind.The invention relates to a bag made of a plastic film, in particular machine bag, with a filling opening, a front wall, a rear wall and in the region of the filling opening, extended rear wall to form a bag flap, wherein the front wall and the rear wall on their longitudinal sides, for the formation of side walls and at one of the filling opening opposite transverse side, to form a bottom seam, are welded together.
Bei der fortlaufenden Herstellung von Beuteln ist es allgemein bekannt, die Beutel in einer vorher bestimmbaren Anzahl, beispielsweise in einer Anzahl von cirka 500 Beuteln, zu so genannten Beutelstapeln in einer Sammelvorrichtung zusammenzutragen. Als Sammelvorrichtung eignet sich beispielsweise eine Stiftstapelfördereinrichtung mit einer sich in horizontaler Richtung bewegenden Stiftstapelförderkette, die auf Stapel stiften die abgetrennten Beutel aufnimmt. In jeden Beutel sind die Stapelöffnungen eingestanzt, deren Abstand die Abstände der Stapelstifte auf der Stiftstapelförderkette entsprechen. Bei der Erzeugung der Beutelstapel ist es ferner bekannt, diese durch einen Drahtbügel (Wicket) zu fixieren und zwar dergestalt, dass Schenkel des Drahtbügels durch die Stapelöffnungen im Klappenteil der Beutel hindurchgeführt werden. Zu diesem Zweck wird entweder der Beutelstapel von den Stapelstiften der Stiftstapelfördereinrichtung abgehoben und mit den nun lose auf einander liegenden Beuteln auf die Schenkel des Drahtbügels aufgesteckt oder die Schenkel des Drahtbügels werden in hohlnutartige Ausnehmungen der Stapelstifte der Stiftstapelförderkette eingesteckt und auf diese Weise der jeweilige Beutelstapel entnommen. Zur Stabilisierung der Beutelstapel und zum Schutz gegen Beschädigung durch die Enden der Drahtbügel bei der gemeinsamen Verpackung mehrerer Beutelstapel werden diese zwischen einem vorderen und hinteren Deckblatt eingelegt und zusätzlich durch auf die Schenkel der Drahtbügel aufgesteckte Sicherungsscheiben bzw. Gummistopfen gesichert. Alle diese Vorgänge werden in der Regel von einer Bedienungsperson manuell ausgeführt und sind in der
Abgesehen von dem beträchtlichen Aufwand an Hilfsmaterialien lassen sich solche Beutelstapel wegen der störrischen Drahtbügel recht schwierig verpacken und transportieren.Apart from the considerable amount of auxiliary materials, such stacks of bags can be packed and transported rather difficult because of the stubborn wire hanger.
Auch beim Abpackvorgang, das heißt beim Befüllen eines Beutels mit einem Produkt, beispielsweise mit einem Hygieneartikel für Damen, Windeln, Brot oder dergleichen, ergeben sich erhebliche Nachteile. Beim Füllvorgang dient der durch die ausgestanzten Stapelöffnungen hindurch geführte Drahtbügel dazu, die Beutelstapel in der Verpackungsmaschine, beispielsweise einem Packautomaten, zu befestigen. Da beim Abpackvorgang das eingefüllte Produkt, zum Beispiel ein Brot zusammen mit dem dieses umschließenden Beutel zusammen abgezogen wird, ergibt es sich, dass der gefüllte Beutel linear zu einer Verschlusseinrichtung befördert wird. Das lineare Abziehen des Beutels mit eingefülltem Produkt erfordert nicht nur einen genau in der Maßführung gestalteten Beutel, sondern es kommt dabei auch zu einem schlagartigen Einreißen der üblicherweise zwischen den Stapelöffnungen und der Stirnkante der Klappe befindlichen Anschnittstelle. Der eingerissene Randbereich der Klappe verleiht dem Beutel insgesamt nicht nur ein unschönes Aussehen, sondern es kommt noch hinzu, dass die Beutelklappenfläche nicht mehr ohne weiteres zur sicheren Befestigung von Verschlusselementen, wie Klebeetiketten oder dergleichen und/oder als Fläche zum Bedrucken oder zur Aufnahme von Hinweisen geeignet ist.Even during the packaging process, that is to say when filling a bag with a product, for example with a hygiene article for ladies, diapers, bread or the like, considerable disadvantages result. During the filling process, the wire bow guided through the punched-out stack openings serves to fasten the stack of bags in the packaging machine, for example a packing machine. Since during the packaging process the filled product, for example a bread, is withdrawn together with the bag enclosing this, it is found that the filled bag is conveyed linearly to a closure device. The linear withdrawal of the bag with filled product not only requires a precisely designed in the measure guide bag, but it also comes to a sudden tearing of the usually located between the stacking openings and the front edge of the flap An interface. The torn edge region of the flap not only gives the bag an unattractive appearance, but it also adds that the bag flap surface is no longer readily for secure attachment of closure elements such as adhesive labels or the like and / or as a surface for printing or for receiving hints suitable is.
Schließlich müssen nach dem Befüllen aller Beutel gegebenenfalls die Drahtbügel wieder zum Hersteller der Beutel zurücktransportiert, nach Größen sortiert und gegebenenfalls aufbereitet werden, damit sie erneut verwendet werden können.Finally, after filling all the bags if necessary, the wire hanger must be transported back to the manufacturer of the bag, sorted by size and optionally processed so that they can be used again.
Um diese Nachteile zu überwinden, ist in der
Der Erfindung liegt die Aufgabe zugrunde, einen Beutelstapel der eingangs genannten Art zu schaffen, der ohne aufwendige Hilfsmittel auskommt, darüber hinaus die Leistungsfähigkeit einer Verpackungsmaschine deutlich erhöht und mit minimalen konstruktiven und materiellem Aufwand zu realisieren ist.The invention has for its object to provide a bag stack of the type mentioned, which requires no expensive tools, beyond the performance of a packaging machine significantly increased and can be realized with minimal design and material expense.
Die Aufgabe wird dadurch gelöst, dass der Beutel eine über die Bodennaht hinausragende Verlängerung aufweist und dass zumindest die Beutelklappe lösbar mit einer Beutelklappe eines weiteren Beutels und die Verlängerung durchgängig und lösbar mit den Beuteln verbunden ist. Durch die erfindungsgemäße Ausgestaltung des Beutels oder vielmehr der miteinander verbundenen Beutel ist nun die Möglichkeit geschaffen einen Automatenbeutel als Rollenware, zum Beispiel in eine Verpackungsmaschine, einzulegen.The object is achieved in that the bag has an extension projecting beyond the bottom seam and that at least the bag flap is releasably connected to a bag flap of another bag and the extension is connected continuously and detachably to the bags. Due to the inventive design of the bag or rather the interconnected bag is now created the possibility of a machine bag as rolls, for example, in a packaging machine to insert.
Durch eine erste lösbare Verbindung zwischen zwei benachbarten Beuteln im Bereich der Beutelklappe und eine zweite Verbindung der Beutel durch die Verlängerung im Bereich der Bodennaht, wird es erfindungsgemäß möglich einen wickelfähiger Beutel bereit zu stellen. Hierbei dient die durchgängige, das heißt sich über alle miteinander verbundenen Beutel erstreckende Verlängerung am unteren Ende des Beutels im Bereich der Bodennaht als Halte- oder Wickelstreifen. Der Halte- oder Wickelstreifen ist lösbar mit den Beuteln verbunden, dies kann zum Beispiel mittels einer Perforation erfolgen, die gemeinsam mit der Herstellung der Schweißung der Bodennaht in den Beutel eingebracht wird. Somit fungiert der Halte- oder Wickelstreifen einerseits als Bindeglied zwischen den Beuteln und anderseits wird ein durchgängiger Kunststofffolienstreifen zum sicheren Fördern der Beutel in der Verpackungsmaschine bereitgestellt. Nach, vor oder während der Befüllung des Beutels wird der Halte- oder Wickelstreifen vom Beutel getrennt und kann separat einsorgt werden, wird der Halte- oder Wickelstreifen in der Verpackungsmaschine ebenfalls wieder aufgerollt wird ein leichtes und Platz sparendes Entsorgen ermöglicht. Die lösbare Verbindung im Bereich der Beutelklappe dient dabei genau wie die Verlängerung im Bereich der Bodennaht als Halte- oder Wickelstreifen, wobei die Beutelklappe als funktionelles Element des Beutels fest mit dem Beutel verbunden ist, wobei die Beutelklappe vorzugsweise als Teil der Rückwand des Beutels ausgebildet ist. Zum sicheren Aufwickeln der Beutel und Führen der Beutel in der Maschine sind die nebeneinander angeordneten Beutelklappen lösbar miteinander verbunden.By a first detachable connection between two adjacent bags in the region of the bag flap and a second connection of the bag through the extension in the region of the bottom seam, it is possible according to the invention to provide a bag capable of being wound. Here, the continuous, that is over all interconnected bags extending extension at the bottom of the bag in the bottom seam serves as a holding or winding strip. The holding or winding strip is detachably connected to the bags, this can be done for example by means of a perforation, which is introduced into the bag together with the production of the weld of the bottom seam. Thus, the holding or winding strip acts on the one hand as a link between the bags and on the other hand, a continuous plastic film strip for safe transport of the bags is provided in the packaging machine. After, before or during the filling of the bag, the holding or winding strip is separated from the bag and can be taken care of separately, the holding or winding strip is also rolled up again in the packaging machine is a lightweight and space-saving disposal allows. The detachable connection in the region of the bag flap serves exactly as the extension in the region of the bottom seam as a holding or winding strip, wherein the bag flap is connected as a functional element of the bag fixed to the bag, wherein the bag flap is preferably formed as part of the rear wall of the bag , For safely winding the bags and guiding the bags in the Machine are the juxtaposed bag flaps detachably connected together.
Bevorzugt werden die Beutelklappen mittels einer Perforation verbunden, so dass ein leichtes Trennen der Beutel in der Verpackungsmaschine realisierbar ist. Hierbei wird an die Perforation einerseits die Anforderung gestellt, dass sie genügend fest ist um ein Wickeln und ein transportieren durch die Maschine zu ermöglichen und andererseits muss die Perforation leicht lösbar sein um ein problemloses Trennen der einzelnen Beutel in der Verpackungsmaschine zu ermöglichen.Preferably, the bag flaps are connected by means of a perforation, so that an easy separation of the bags in the packaging machine can be realized. On the one hand, the requirement is placed on the perforation that it is strong enough to allow it to be wrapped and transported through the machine and, on the other hand, the perforation must be easily detachable in order to enable a problem-free separation of the individual bags in the packaging machine.
Durch den erfindungsgemäßen Einsatz von gewickelten Beuteln in Verpackungsmaschinen wird die in der Maschine zur Verfügung stehende Anzahl von Beuteln deutlich erhöht. Sind auf einem nach dem Stand der Technik bekannten Beutelstapel cirka 500 Beutel vorhanden, so ist es durch das Wickeln der Beutel zu einer Beutelrolle möglich je nach Beutelgröße, Durchmesser der Rolle und Dicke der Folie ein Vielfaches an Beuteln auf eine Rolle oder in sich selbst aufzuwickeln. Dies bietet wiederum den Vorteil, dass ein Bediener der Maschine weniger Zeit für die Bestückung der Verpackungsmaschine aufwenden muss, was sich wiederum positiv auf die Nebenzeiten, insbesondere die Bestückungszeiten, der Maschine auswirkt.The use of wound bags in packaging machines according to the invention significantly increases the number of bags available in the machine. If approximately 500 bags are present on a bag stack known from the prior art, it is possible to wind a multiple of bags onto a roll or into itself by winding the bags into a roll of bags depending on the size of the bag, the diameter of the roll and the thickness of the film , This in turn has the advantage that an operator of the machine must spend less time for the assembly of the packaging machine, which in turn has a positive effect on the non-productive time, in particular the loading times of the machine.

Die Beutel 2 sind aus einer Kunststofffolie hergestellt, die bevorzugt eine thermoplastische Kunststofffolie ist, die eine Dicke von 20 µm bis 100 µm, bevorzugt mit
einer Dicke von 35 µm bis 80 µm, aufweist. Ein bevorzugter Kunststoff ist hierbei Polyethylen (PE).The bags 2 are made of a plastic film, which is preferably a thermoplastic film, which has a thickness of 20 .mu.m to 100 .mu.m, preferably with
a thickness of 35 .mu.m to 80 .mu.m. A preferred plastic here is polyethylene (PE).
Entlang der Bodenfalte 5 des Beutels verläuft eine Bodennaht 6, wobei in diesem Ausführungsbeispiel zwei Bodennähte 6, 7, einmal an der Vorderwand 3 und einmal an der Rückwand 4 vorhanden sind. Im Bereich einer Beutelöffnung 8 besitzt der Beutel 2 eine Beutelklappe 9, die aus einem Teil der Rückwand 4 gebildet wird. Mittels der Beutelklappe 9 ist der Beutel 2 nach dem Befüllen verschließbar, wie beispielsweise in der
Alternativ ist es erfindungsgemäß ebenfalls vorstellbar, die Beutel 2 aus einem Halbschlauch herzustellen, wobei während der Faltung der Bodenfalte 5 aus dem Halbschlauch gleichzeitig die Vorderwand 3 und die Rückwand 4 auszubilden.
