Description

Die Erfindung betrifft einen Beutelstapel aus einer Vielzahl von miteinander verbundenen Beuteln aus einer Kunststofffolie, insbesondere Automatenbeuteln, wobei jeder Beutel aus einer Vorderwand und einer Rückwand gebildet ist und die Rückwand im Bereich einer Öffnung länger als die Vorderwand ausgebildet ist und der Beutelstapel an der Rückwand und an dem zur Vorderwand längeren Ende verschweißt ist. Die Erfindung betrifft weiterhin eine Vorrichtung in einer Beutelherstellmaschine zum Trennen von Beutelstapeln, in der das Trennmesser relativ zum Beutelstapel bewegbar ist.The invention relates to a bag stack of a plurality of interconnected bags made of a plastic film, in particular machine bags, each bag is formed of a front wall and a rear wall and the rear wall is formed in the region of an opening longer than the front wall and the bag stack on the rear wall and is welded to the front wall longer end. The invention further relates to a device in a bag making machine for separating bag stacks, in which the separating knife is movable relative to the bag stack.

Es ist heute allgemein üblich, dass dem Verbraucher in zum Beispiel Einkaufsmärkten Beutel zur Verfügung gestellt werden, um frische Lebensmittel zu verpacken. Hierbei werden die Beutel als Beutelstapel bereitgestellt, wobei die Beutel zu einem Beutelstapel verschweißt beziehungsweise verblockt sind.It is now commonplace for consumers to be provided with bags in, for example, shopping markets to package fresh food. Here, the bags are provided as a stack of bags, wherein the bags are welded or blocked to a bag stack.

Ein derartiger Beutelstapel ist beispielsweise in der DE 199 35 064 A1 beschrieben. Beschrieben ist ein Stapel aus einer Vielzahl von miteinander verbundenen Beuteln aus Kunststofffolie, die in einer einseitigen Klappe durch Perforationslinien begrenzte Eckenperforationsabschnitte mit einer jeweils in deren Bereich angeordneten Verblockungsstelle aufweisen. Hierdurch ist die Möglichkeit gegeben, die einzelnen Beutel von den Verblockungsstellen an der Perforation zu lösen. Nachteilig ist hierbei, dass ein sogenannter Restbutzen, nämlich der Bereich in dem der Beutelstapel verblockt wurde, als Restabfall übrig bleibt.Such a bag stack is for example in the DE 199 35 064 A1 described. Described is a stack of a plurality of interconnected bags made of plastic film, which have in a one-sided flap by perforation lines limited Eckenperforationsabschnitte with each arranged in their area Verblockungsstelle. This gives the possibility to solve the individual bags from the Verblockungsstellen at the perforation. The disadvantage here is that a so-called Restbutzen, namely the area in which the bag stack has been blocked remains as residual waste.

Eine weitere Möglichkeit Beutelstapel zu bilden, ist in der Gebrauchsmusterschrift DE 74, 29 628 U beschrieben. Beschrieben ist ein Stapel von Beuteln aus thermoplastischem Werkstoff, der in einem oder in beiden an der Öffnungsseite der Beutel befindlichen Eckbereichen der Stapel eine oder mehrere alle Beutel erfassende Verschweißung sowie ein Aufhängeloch aufweist. In einem Ausführungsbeispiel des Gebrauchsmusters ist ein Beutelstapel beschrieben, der nur einen geringen oder möglicherweise keinen Restbutzen dadurch aufweist, dass der Beutelstapel an den rechtwinklig aneinanderstoßenden Seitenkanten verschweißt ist.Another way to form bag stack is in the utility model DE 74, 29 628 U described. Described is a stack of bags made of thermoplastic material, which has in one or in both located at the opening side of the bag corner regions of the stack one or more all bag-detecting welding and a hanging hole. In one embodiment of the utility model, a bag stack is described which only a small or may not have residual scraps in that the bag stack is welded to the right angle abutting side edges.

Die Aufgabe der Erfindung besteht darin, einen Beutelstapel bereitzustellen, der die Nachteile des Standes der Technik überwindet und der einen Beutelstapel bereitstellt, der stabil handhabbar, leicht zu fertigen und konstruktiv einfach aufgebaut ist. Darüber hinaus ist es Aufgabe der Erfindung, eine Vorrichtung in einer Beutelherstellmaschine bereitzustellen, mittels der ein erfindungsgemäßer Beutelstapel herstellbar ist.The object of the invention is to provide a bag stack which overcomes the disadvantages of the prior art and which provides a bag stack which is stable to handle, easy to manufacture and structurally simple. In addition, it is an object of the invention to provide a device in a bag making machine, by means of which an inventive bag stack can be produced.

Die erfindungsgemäße Aufgabe wird in Bezug auf das Erzeugnis Beutelstapel dahingehend gelöst, dass der Beutelstapel über seine Breite verteilt mindestens drei Verschweißungen an einem Ende der Rückwand des Beutelstapels aufweist, so dass ein stabiler Beutelstapelrand gebildet ist. Durch die erfindungsgemäße Ausbildung des Beutelstapels ist nun die Möglichkeit gegeben, die Beutelstapel leicht zu handhaben, da durch die Mehrfachverschweißung des Rands des Beutelstapels der Rand stabilisiert wird, so dass der Rand leicht zu ergreifen und auch lagegerecht positionierbar ist. Besonders vorteilhaft ist es hierbei, die Verschweißungen in regelmäßigen Abständen zwischen den Verschweißungen am Rand des Beutelstapels anzubringen. Das Anbringen der Verschweißungen mit Abstand von den Längsseiten des Beutels am Beutelstapelrand und eine beispielsweise mittige Verschweißung ermöglicht ein passgenaues Ausrichten des Beutelstapels, da dieser in den Eckbereichen eine rechtwinklige Kontur aufweist, da die Ecken des Beutelstapels nicht durch eine Verschweißung deformiert sind. In seiner einfachsten Ausführungsform weist der erfindungsgemäße Beutelstapel somit eine in Bezug auf eine Vorderwand längere Rückwand auf und besitzt eine Einfüllöffnung, die auch als Klappe bezeichnet wird, dabei ist der Beutelstapel mit zwei vom seitlichen Rand des Beutelstapels beabstandeten Randverschweißungen und einer mittig angeordneten Verschweißung versehen. Darüber hinaus ist es natürlich ebenfalls vorstellbar, die Beutel des Beutelstapels mit Aufhängelöchern und/oder Sollbruchstellen, wie beispielsweise Perforationen wie sie aus dem Stand der Technik bekannt sind, und/oder Bodenfalten und/oder Seitenfalten und/oder Klappen zu versehen.The object according to the invention is achieved in relation to the product bag stack in such a way that the bag stack has at least three welds distributed over its width at one end of the rear wall of the bag stack, so that a stable bag stack edge is formed. The inventive design of the bag stack is now given the opportunity to easily handle the bag stack, as stabilized by the Mehrfachverschweißung of the edge of the bag stack, the edge so that the edge is easy to grasp and also positionally positioned. It is particularly advantageous here to attach the welds at regular intervals between the welds on the edge of the bag stack. The attachment of the welds at a distance from the longitudinal sides of the bag at the bag stack edge and an example central weld allows a precise alignment of the bag stack, since this has a rectangular contour in the corner areas, since the corners of the bag stack are not deformed by a weld. In its simplest embodiment, the bag stack according to the invention thus has a longer rear wall with respect to a front wall and has a filling opening, which is also referred to as a flap, while the bag stack is provided with two spaced apart from the lateral edge of the bag stack edge welds and a centrally disposed weld. Moreover, it is of course also conceivable to provide the bags of the bag stack with hanging holes and / or predetermined breaking points, such as perforations as known from the prior art, and / or bottom folds and / or gussets and / or flaps.

Die Aufgabe der Erfindung ist es weiterhin, eine Beutelherstellmaschine mit einer Vorrichtung bereitzustellen, in der ein erfindungsgemaßer Beutelstapel leicht und mit minimalstem konstruktivem Aufwand und kostengünstig herzustellen. Darüber hinaus soll die Vorrichtung leicht in vorhandene Beutelherstellmaschinen integrierbar sein. Derartige Beutelherstellmaschinen, die mit mindestens einem Trennmesser zum Trennen von Doppelbeutelstapeln versehen sind, sind allgemein bekannt, wobei nur beispielhaft auf die DE 199 17 284 verwiesen wird.The object of the invention is furthermore to provide a bag making machine with a device in which a bag stack according to the invention can be produced easily and inexpensively with the least amount of constructive effort. In addition, the device should be easy to integrate into existing bag making machines. Such bag making machines, with at least one cutting knife for Disconnecting double bag stacks are provided, are well known, with only an example of the DE 199 17 284 is referenced.

Die Aufgabe in Bezug auf die Vorrichtung in einer Beutelherstellmaschine zum Trennen von Doppelbeutelstapeln wird erfindungsgemäß dadurch gelöst, dass am Trennmesser voneinander beabstandete aus einem Werkstoff mit einer hohen Wärmeleitfähigkeit gebildete Streifen befestigt sind und dass das Trennmesser und/oder jeder Streifen beheizt ist. Durch die erfindungsgemäße Anbringung von Streifen hoher Wärmeleitfähigkeit an das Trennmesser ist nun die Möglichkeit geschaffen, Beutelstapel unmittelbar bei der Trennung von Doppelstapeln miteinander zu verschweißen. Da hierzu die vorliegenden Trennmesser eingesetzt werden können, da diese lediglich leicht modifiziert werden, ist die Vorrichtung mit minimalstem konstruktivem Aufwand und kostengünstig herzustellen. Bevorzugt wird als Werkstoff für die Streifen Kupfer eingesetzt, da Kupfer eine sehr hohe Wärmeleitfähigkeit besitzt.The object with respect to the device in a bag making machine for separating double bag stacks is achieved according to the invention by fastening strips spaced from each other from a material having a high thermal conductivity and having the separating knife and / or each strip heated. By attaching strips of high thermal conductivity to the separating knife according to the invention, it is now possible to weld together bag stacks directly in the separation of double stacks. Since the present separating blades can be used for this purpose, since they are only slightly modified, the device can be produced with minimal constructive effort and at low cost. Preferably, copper is used as the material for the strips, since copper has a very high thermal conductivity.

In einer bevorzugten Ausführungsvariante sind die Streifen spitz in Richtung der Schneide des Trennmessers ausgeführt. Spitz heißt hierbei, dass die Streifen mit einer rechteckigen Querschnittsform parallel zum Trennmesser auf dem Trennmesser befestigt sind und dass die rechteckige Querschnittsform spitz in Richtung der Schneide des Trennmessers ausläuft. Bevorzugt wird ein Winkel von 30° angestrebt. Es ist auch möglich, das obere Ende des Streifens trapezförmig auszubilden, so dass breitere Verschweißungen erzielbar sind. In einer weiteren vorteilhaften Ausführungsform ist der spitz zulaufende Streifen abgeschrägt, das heißt, die Dicke des rechteckigen Streifens verjüngt sich in Richtung der Schneide des Trennmessers, bevorzugt in einem Winkel von ca. 10°. Darüber hinaus ist es vorteilhaft, die Streifen in einem Abstand von ca. 100 mm und noch vorteilhafter in einem Abstand von 95 mm zueinander am Trennmesser zu befestigen. Der Abstand bezieht sich hierbei auf die Spitzen der Streifen. Alternativ sind die Streifen in Abständen von 20 mm bis 200 mm auf dem Trennmesser befestigbar.In a preferred embodiment, the strips are pointed in the direction of the cutting edge of the cutting blade. Spitz here means that the strips are fixed with a rectangular cross-sectional shape parallel to the cutting blade on the cutting blade and that the rectangular cross-sectional shape terminates pointedly in the direction of the cutting edge of the cutting blade. Preferably, an angle of 30 ° is desired. It is also possible to make the upper end of the strip trapezoidal, so that wider welds can be achieved. In a further advantageous embodiment, the tapered strip is chamfered, that is, the thickness of the rectangular strip tapers in the direction of the cutting edge of the cutting blade, preferably at an angle of about 10 °. Moreover, it is advantageous to fasten the strips at a distance of about 100 mm and even more advantageously at a distance of 95 mm from each other on the separating knife. The distance here refers to the tips of the strips. Alternatively, the strips can be fastened on the separating knife at intervals of 20 mm to 200 mm.

For the sake of clarity, only a strip 23 and a distance A has been provided with reference numerals. In the lower part of the FIG. 2 is a plan view in the direction of arrow P on the cutting blade 14 is shown. On both sides of the separating knife 14 strips 23, 24 are attached. A mounting flange 25 arranged below the separating knife simultaneously carries a heating device, not shown, by means of which the separating knife 14 and / or the strips 23, 24 can be heated. If only the mounting flange 25 is heated, on the one hand the separating blade 14 heats up, whereby the strips 23, 24 heat up to a greater extent, since they are made of a material with a higher thermal conductivity. This temperature difference between the separating knife 14 and the strips 23, 24 is sufficient to weld the bag stack 2, 3 in the regions 16 and on the other hand to separate the double bag stack 1.

In der Figur 3 ist einerseits der Schnitt gemäß der Linie III-III zu erkennen und andererseits eine Draufsicht auf einen Streifen 23, 24 sowie zwei unterschiedliche Seitenansichten. Wie aus dem Schnitt III-III zu erkennen, sind die Streifen 23, 24 plan auf dem Trennmesser 14 befestigt und besitzen eine Schräge, die mit der Schräge des Trennmessers 14 im Wesentlichen übereinstimmt. Die Figur 3 zeigt weiterhin die Draufsicht auf einen Streifen 23, 24, wobei die an den Streifen 23, 24 angebrachte Spitze Z deutlich zu erkennen ist und beispielhaft mit 30° angegeben ist. Die beiden Seitenansichten auf den Streifen 23, 24 zeigen die unterschiedliche Ausbildung der Schrägen S mit 10° und 15°. Anzumerken bleibt hierbei noch, dass der Abstand A zwischen den Streifen im Mittel etwa 100 mm beträgt. Bevorzugt wird ein Abstand A von 95 mm eingestellt.In the FIG. 3 on the one hand to recognize the section along the line III-III and on the other hand, a plan view of a strip 23, 24 and two different side views. As can be seen from the section III-III, the strips 23, 24 are mounted flat on the cutting blade 14 and have a slope which substantially coincides with the slope of the cutting blade 14. The FIG. 3 further shows the top view of a strip 23, 24, wherein the attached to the strip 23, 24 tip Z is clearly visible and is exemplified with 30 °. The two side views on the strips 23, 24 show the different design of the bevels S with 10 ° and 15 °. It should be noted here that the distance A between the strips is on average about 100 mm. Preferably, a distance A of 95 mm is set.
