Description
Verfahren und Vorrichtung zum Beschichten einer aus Papier bestehenden Materialbahn mit heißsiegelfähigem LeimMethod and apparatus for coating a web of paper with heat-sealable glue
Stand der TechnikState of the art
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Beschichten einer aus Papier bestehenden Materialbahn mit heißsiegelfähigem Leim.The invention relates to a method and an apparatus for coating a paper web consisting of heat-sealable glue.
Aus der DE 41 17 428 AI ist bereits ein Verfahren mit den Merkmalen des Oberbegriffs des Anspruchs 1 bekannt. Bei dem bekannten Verfahren werden lediglich auf einer Seite der Materialbahn ein Leimbild aufgebracht. Anschließend wird die Materialbahn mittels einer Falteinrichtung so gefaltet, dass Bereiche der Materialbahn, an denen das Leimbild aufgebracht ist, gegeneinander zur Anlage kommen und Längs- bzw. Quernähte ausbilden. Mit dem bekannten Verfahren bzw. der beschriebenen Vorrichtung ist es möglich, sogenannte Flachbeutelpackungen herzustellen.From DE 41 17 428 Al a method with the features of the preamble of claim 1 is already known. In the known method, a glue pattern are applied only on one side of the web. Subsequently, the material web is folded by means of a folding device so that areas of the material web on which the glue pattern is applied, come to rest against each other and form longitudinal or transverse seams. With the known method or the device described, it is possible to produce so-called flat bag packages.
Ferner ist es aus der DE 198 52 693 AI bekannt, bei einer für die Herstellung von Zigarettenpackungen verwendeten Materialbahn ebenfalls einseitig ein Leimbild aus Heißsiegelkleber aufzubringen, wobei die Materialbahn zu quaderförmigen Zigarettenpackungen gefaltet wird. Neben der aus der DE 41 17 428 AI bekannten Lehre, die Menge des Heißsiegelklebers auf Papier zu begrenzen, um damit den Packstoff als recycelbar einstufen zu können, ist es für einen Abpacker insbesondere interessant, insgesamt möglichst wenig Packstoff zu verwenden, damit die Herstellkosten der Packungen reduziert werden können.It is also known from DE 198 52 693 AI, also applied on one side of a material web used for the production of cigarette packs a glue pattern of heat seal adhesive, wherein the web is folded into cuboid cigarette packs. In addition to the teaching known from DE 41 17 428 AI to limit the amount of heat seal adhesive on paper in order to classify the packaging material as recyclable, it is particularly interesting for a packer to use a total of as little packaging material, so that the production costs of Packs can be reduced.
Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren zum Beschichten einer aus Papier bestehenden Materialbahn mit heißsiegelfähigem Leim mit den kennzeichnenden Merkmalen des Anspruchs 1 hat den Vorteil, dass nach dem Verfahren hergestellte Packungen nicht nur als recycelfähig gelten, sondern darüber hinaus bezüglich ihres Packstoffverbrauchs minimiert sind. Dies wird erfindungsgemäß dadurch erreicht, dass die Beschichtung auf einander gegenüberliegenden Seiten der Packstoffbahn, d.h. sowohl auf der Ober-, als auch auf der Unterseite der Packstoffbahn aufgebracht wird und dass diejenigen miteinander zusammenwirkenden Bereiche der Heißsiegelkleberschicht, welche die Längsnaht der Packung ausbilden, mittels der Einrichtung zum Formen der Packungen derart gegeneinander gelegt werden, dass im Bereich der Längsnaht die Oberseite der Packstoffbahn gegen die Unterseite trifft. Dadurch lässt sich insofern der Packstoffverbrauch minimieren bzw. optimieren, als die so hergestellte Längsnaht bei Zugbeanspruchung in der Packstoffwand nicht zum sogenannten Aufgeschälen neigt, so dass schon relativ schmale Verbindungsbereiche genügen, um die erforderliche Festigkeit der Packung zu erreichen.The inventive method for coating a paper web consisting of heat-sealable glue with the characterizing features of claim 1 has the advantage that packs produced by the method are not only considered recyclable, but are also minimized in terms of their packaging material consumption. This is inventively achieved in that the coating on opposite sides of the packaging material web, i. is applied both on the top, and on the underside of the packaging material web and that those cooperating areas of the heat seal adhesive layer, which form the longitudinal seam of the pack, are placed against each other by means of the means for forming the packs such that in the region of the longitudinal seam, the top the packaging material web meets the underside. As a result, the consumption of packaging material can be minimized or optimized insofar as the longitudinal seam produced in this way does not tend to become so-called peeling in tensile stress in the packaging material wall, so that even relatively narrow connection regions are sufficient to achieve the required strength of the package.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens zum Beschichten einer aus Papier bestehenden Materialbahn mit heißsiegelfähigem Leim sind in den Unteransprüchen angegeben. Eine bevorzugte Vorrichtung zum Durchführen des erfindungsgemäßen Verfahrens zeichnet sich durch die Verwendung einer an sich bekannten Schlauchbeutelmaschine mit einer Formschulter aus. Es ist an sich bekannt, dass derartige Schlauchbeutelmaschinen hinsichtlich der Herstellkosten pro Packung gegenüber anderen Maschinen, beispielsweise sogenannten Dornradmaschinen, wirtschaftlicher sind. Der Einsatz derartiger Schlauchbeutelmaschinen zur Herstellung von Packungen aus einer Materialbahn, welche mit heißsiegelfähigem Leim beschichtet ist, ist jedoch bisher nicht bekannt.Advantageous developments of the method according to the invention for coating a material web consisting of paper with heat-sealable glue are specified in the subclaims. A preferred device for carrying out the method according to the invention is characterized by the use of a known per se bag machine with a forming shoulder. It is known per se that such tubular bag machines are more economical in terms of production costs per package compared with other machines, for example so-called mandrel wheel machines. The use of such tubular bag machines for the production of packages from a material web which is coated with heat-sealable glue, however, is not yet known.

In der Figur 1 ist eine Beutelpackung 10 dargestellt, wie sie beispielsweise zum Verpacken von Lebensmitteln wie Mehl, Zucker o.a. verwendet wird. Die Beutelpackung 10 ist als sogenannte Standbeutelpackung ausgebildet, deren quaderförmiger Körper jeweils zwei relativ schmale Seitenwände 11, sowie eine relativ breite Vorderwand 12 und eine Rückwand aufweist. Ferner ist ein flachgefalteter Kopfverschluss 13 mit einer gesiegelten Quernaht 14 vorhanden. Der Bodenbereich der Beutelpackung 10 weist ebenfalls eine Quernaht auf, die jedoch gegen den Boden umgelegt ist, damit die Beutelpackung 10 standfähig ist. An der Vorderwand 12 ist eine Längsnaht 15 erkennbar, die über die gesamte Höhe der Beutelpackung 10 reicht, und in etwa mittig in der Vorderwand 12 angeordnet ist.FIG. 1 shows a bag pack 10, as used, for example, for packaging foods such as flour, sugar or the like. is used. The bag package 10 is formed as a so-called stand-up pouch package whose cuboid body has two relatively narrow side walls 11, and a relatively wide front wall 12 and a rear wall. Furthermore, a flat-folded head closure 13 with a sealed transverse seam 14 is present. The bottom portion of the bag package 10 also has a transverse seam but which is folded against the ground to allow the bag package 10 to stand firm. On the front wall 12, a longitudinal seam 15 can be seen, which extends over the entire height of the bag pack 10, and is arranged approximately centrally in the front wall 12.
Erfindungsgemäß ist vorgesehen, dass die Beutelpackung 10 aus recycelfähigem Material, insbesondere aus Papier besteht, wobei die Quernähte 14 und die Längsnaht 15 durch eine Beschichtung mittels Heißsiegelkleber ausgebildet werden. Das Massenverhältnis zwischen dem Papier und dem Heißsiegelkleber pro Beutelpackung 10 sollte dabei bevorzugt so gewählt werden, dass der Heißsiegelkleber maximal 5% der Masse des Packstoffes beträgt, um die gesetzliche Forderung der Recyclebarkeit zu gewährleisten. Um die Beutelpackung 10 hinsichtlich ihres Packstoffverbrauches sowie des Verbrauches an Heißsiegelkleber zu optimieren, sind verschiedene Maßnahmen vorgesehen, die nunmehr erläutert werden.According to the invention, it is provided that the bag pack 10 consists of recyclable material, in particular of paper, wherein the transverse seams 14 and the longitudinal seam 15 are formed by a coating by means of heat-sealable adhesive. The mass ratio between the paper and the heat-seal adhesive per bag pack 10 should preferably be selected so that the heat seal adhesive is at most 5% of the mass of the packaging material to ensure the legal requirement of recyclability. In order to optimize the bag package 10 with regard to its packaging material consumption and the consumption of hot-seal adhesive, various measures are provided, which will now be explained.
In der Figur 2 ist der Querschnitt im Bereich des Kopfverschlusses 13 der Beutelpackung 10 dargestellt. Man erkennt die Längsnaht 15, die durch Übereinanderlegen der seitlichen Randbereiche einer Packstoffbahn 16 gebildet ist. Wesentlich dabei ist, dass dabei die Außenseite 17 des einen Randbereichs gegen die Innenseite 18 des anderen Randbereichs der Packstoffbahn 16 gelegt ist. Im Gegensatz dazu ist in der Figur 3 der Kopfbereich einer üblicherweise verwendeten Längsnaht dargestellt, deren Längsnaht 15a durch Gegeneinanderlegen beispielsweise jeweils der Innenseite einer Packstoffbahn 16a gebildet ist, wobei die Längsnaht 15a anschließend gegen die flache Vorderwand umgelegt ist. Die Ausführungsform gemäß der Figur 2 hat gegenüber der Ausführungsform gemäß der Figur 3 zum einen den Vorteil eines geringeren Packstoffverbrauches und zum zweiten gleichzeitig den Vorteil einer höheren Festigkeit, da bsw. durch Innendruck in der Vorderwand der Beutelpackung 10 wirkende Kräfte bei der Ausführungsform gemäß der Figur 2 als Zugkräfte in der Ebene des Packstoffes auftreten, während bei der Ausführungsform gemäß Figur 3 die Zugkräfte in der Packstoffbahn 16a zu einem Auseinanderziehen der Längsnaht 15a durch Schälwirkung im Bereich 19 führen kann.FIG. 2 shows the cross section in the region of the head closure 13 of the bag pack 10. One recognizes the longitudinal seam 15, which is formed by superposition of the lateral edge regions of a packaging material web 16. It is essential that while the outside 17 of the one Edge region is placed against the inner side 18 of the other edge region of the packaging material web 16. In contrast, in FIG. 3 the head region of a commonly used longitudinal seam is shown, whose longitudinal seam 15a is formed by facing each other, for example, on the inside of a packaging material web 16a, wherein the longitudinal seam 15a is subsequently folded against the flat front wall. The embodiment according to FIG. 2 has, compared to the embodiment according to FIG. 3, on the one hand the advantage of lower packaging material consumption and on the other hand the advantage of higher strength at the same time. In the embodiment according to FIG. 3, the tensile forces in the packaging material web 16a cause the longitudinal seam 15a to be pulled apart by peeling in the region 19 can lead.
In der Figur 4 ist ein Zuschnitt 21 einer Papiermaterialbahn dargestellt, wie er für die Beutelpackung 10 verwendet wird. Man erkennt zwei parallel zueinander angeordnete Beschichtungszonen 22, 23, welche die spätere obere Quernaht 14 bzw. die Quernaht im Bereich des Bodens ausbilden. Randseitig sind ferner zwei Beschichtungszonen 24, 25 ersichtlich, welche zum Bilden der Längsnaht 15 dienen. Wesentlich dabei ist, dass die Beschichtungszonen 22, 23 und 24 alle auf einer Seite des Zuschnittes 21, beispielsweise auf der Innenseite, aufgebracht sind, während die eine Beschichtungszone 25 auf der anderen Seite des Zuschnittes 21, also im Ausführungsbeispiel auf der Außenseite, aufgebracht ist.FIG. 4 shows a blank 21 of a paper material web as used for the bag package 10. It can be seen two coating zones 22, 23 arranged parallel to one another, which form the later upper transverse seam 14 or the transverse seam in the region of the bottom. Furthermore, two coating zones 24, 25, which serve to form the longitudinal seam 15, can be seen on the edge side. It is essential that the coating zones 22, 23 and 24 are all applied on one side of the blank 21, for example on the inside, while the one coating zone 25 is applied on the other side of the blank 21, ie on the outside in the exemplary embodiment ,
In der Figur 5 ist ein modifizierter Zuschnitt 21a dargestellt, welcher ebenfalls Beschichtungszonen 22a bis 25a aufweist, wobei die Beschichtungszonen 22a und 23a in dem Bereich unterbrochen ausgebildet sind, in denen der Zuschnitt 21a zum Bilden des Kopfverschlusses bzw. des Bodenverschlusses V-förmig eingefaltet ist. Das Unterbrechen der Beschichtungszonen 22a und 23a hat den Vorteil eines minimierten Heißsiegelklebverbrauches . Zusätzlich wird erwähnt, dass die Beschichtungszonen 22, 23 und 22a, 23a eine größere Stärke bzw. Dicke aufweisen sollten als die Beschichtungszonen 24, 25 und 24a, 25a, um die im Bereich der Quernähte auftretenden Lagensprünge, d.h. die über den Verlauf der Quernähte unterschiedliche Anzahl an Packstofflagen auszugleichen, damit eine genügende Dichtigkeit bzw. Festigkeit der Quernähte erzielt wird.A modified blank 21a is shown in FIG. 5, which likewise has coating zones 22a to 25a, the coating zones 22a and 23a being interrupted in the region in which the coating zone 22a and 23a are formed Blank 21a for forming the head closure and the bottom closure is folded V-shaped. The interruption of the coating zones 22a and 23a has the advantage of minimized heat-seal adhesive consumption. In addition, it is mentioned that the coating zones 22, 23 and 22a, 23a should have a greater thickness than the coating zones 24, 25 and 24a, 25a by the layer jumps occurring in the region of the transverse seams, ie the differences over the course of the transverse seams To balance the number of packaging material layers, so that a sufficient tightness or strength of the cross seams is achieved.
In der Figur 6 ist eine erste Verpackungsanlage 30 zum Herstellen der Beutelpackungen 10 stark vereinfacht dargestellt. Die Verpackungsanlage 30 weist eine mit der Bezugsziffer 31 bezeichnete Schlauchbeutelmaschine und eine Beschichtungseinrichtung 32 auf. Die Schlauchbeutelmaschine 31, welche sowohl als getaktet, als auch als kontinuierlich arbeitende Schlauchbeutelmaschine 31 ausgebildet sein kann, ist eine herkömmliche Schlauchbeutelmaschine, wie sie aus dem Stand der Technik bekannt ist. Die Schlauchbeutelmaschine 31 weist insbesondere eine Formschulter 33 und ein mit der Formschulter 33 verbundenes Formrohr 34 auf. Über die Formschulter 33 und das Formrohr 34 wird eine Materialbahn 35 mittels nicht dargestellter Einrichtungen gezogen und zunächst zu einem Schlauch geformt, aus dem durch entsprechende Faltorgane die Beutelpackungen 10 gebildet werden. Am bzw. unterhalb des Formrohres 34 sind Siegeleinrichtungen 36, 37 dargestellt, welche zum Bilden der Längsnähte 15, 15a bzw. der Quernähte an den Beutelpackungen 10 durch Aktivierung der Heißsiegelkleberschicht an den Beschichtungszonen 22 bis 25 bzw. 22a bis 25a dienen.In FIG. 6, a first packaging installation 30 for producing the bag packs 10 is shown greatly simplified. The packaging installation 30 has a flow-wrap machine designated by the reference numeral 31 and a coating device 32. The tubular bag machine 31, which can be configured both as a clocked and as a continuous tubular bag machine 31, is a conventional bagging machine, as known from the prior art. The tubular bag machine 31 has in particular a forming shoulder 33 and a forming tube 34 connected to the forming shoulder 33. About the forming shoulder 33 and the forming tube 34, a material web 35 is pulled by means not shown and initially formed into a tube from which the bag packages 10 are formed by appropriate folding organs. On or below the forming tube 34 are sealing means 36, 37 are shown, which serve to form the longitudinal seams 15, 15a and the transverse seams on the bag packages 10 by activation of the heat seal adhesive layer to the coating zones 22 to 25 and 22a to 25a.
Die modulartig mit der Schlauchbeutelmaschine 31 verbundene Beschichtungseinrichtung 32 weist insbesondere zwei Auftragseinrichtungen 38, 39 für den Heißsiegelleim auf, welche auf unterschiedlichen Seiten der Materialbahn 35 angeordnet sind und dazu dienen, die Beschichtungszonen 22 bis 25 bzw. 22a bis 25a auf die Materialbahn 35 aufzubringen. Den beiden Auftragseinrichtungen 38, 39 sind zwei Trocknungseinrichtungen 41, 42 nachgeschaltet, die ebenfalls auf unterschiedlichen Seiten der Materialbahn 35 angeordnet sind, und die die zuvor aufgebrachten Beschichtungszonen 22 bis 25 bzw. 22a bis 25a trocknen, so. dass die Materialbahn 35 in der Schlauchbeutelmaschine 31 weiterverarbeitet werden kann, ohne dass es zu Betriebsstörungen aufgrund nicht oder nicht genügend getrocknetem Heißsiegelkleber kommt. Zuletzt wird erwähnt, dass die Materialbahn 35 als endlose Packstoffrolle 43 bevorratet ist, und von dieser der Beschichtungseinrichtung 32 zugeführt wird.The coating device 32, which is connected in a modular manner to the tubular bag machine 31, has in particular two Applicators 38, 39 for the heat-sealing glue, which are arranged on different sides of the material web 35 and serve to apply the coating zones 22 to 25 or 22a to 25a to the material web 35. The two applicators 38, 39 are two drying devices 41, 42 downstream, which are also arranged on different sides of the web 35, and dry the previously applied coating zones 22 to 25 or 22a to 25a, so. that the material web 35 can be further processed in the tubular bag machine 31, without causing malfunction due to not or not enough dried hot-melt adhesive. Finally, it is mentioned that the material web 35 is stored as an endless packaging material roll 43, and is supplied by the latter to the coating device 32.
Die Verpackungsanlage 30a gemäß der Figur 7 unterscheidet sich von der Verpackungsanlage 30 gemäß Figur 6 im Wesentlichen dadurch, dass der Bereich derThe packaging installation 30a according to FIG. 7 differs from the packaging installation 30 according to FIG. 6 substantially in that the area of the
Schlauchbeutelmaschine 31a und der Beschichtungseinrichtung 32a innerhalb eines gemeinsamen Gehäuses 45 angeordnet sind. Die Verpackungsanlage 30a bildet somit eine speziell auf den Anwendungsfall von beschichteten Materialbahnen ausgebildete Maschine, die hinsichtlich beispielsweise ihres Raumbedarfs optimiert ist. Tubular bag machine 31a and the coating device 32a are arranged within a common housing 45. The packaging system 30a thus forms a specially designed for the application of coated material webs machine, which is optimized in terms of, for example, their space requirements.
