Abstract

The device disclosed is designed to produce a hot-bonded joint between cardboard and transparent foil, with a nozzle for applying hot liquid adhesive to the bond line. The nozzle (DK) is located at a relatively short distance from a roller press (RP) which presses the overlapping edges of the strip of cardboard (Kb) and the strip of transparent foil (Tf) together. The nozzle (DK) is disposed so that the liquid adhesive is applied directly to the transparent foil with the cardboard and foil strips moving at a relatively high speed in order to avoid the transparent foil being damaged by the liquid adhesive being at too high a temperature.

Description

Vorrichtung zur Herstellung einer Heissleimnaht zwischen einem Karton und einer Transparentfolie Device for producing a hotmelt seam between a cardboard box and a transparent film

Die vorliegende Erfindung betrifft eine Vorrichtung zur Herstellung einer Heissleimnaht zwischen einem Karton und einer Transparentfolie gemäss dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device for producing a hotmelt seam between a carton and a transparent film according to the preamble of claim 1.

Es sind Vorrichtungen bekannt, die einen Düsenkopf zum Anbrin¬ gen eines Kleberstreifens auf einen Rand eines Kartons aufweisen, auf den nachträglich ein Rand einer Transparentfo¬ lie gepresst wird, um damit eine Klebverbindung, auch Heiss¬ leimnaht genannt, zwischen dem Karton und der Transparentfolie, insbesondere zur Herstellung von Mäppchen, zu erzeugen. Der Kleberstreifen ist ein sogennanter "Heisskleber" oder PS- Kleber, der bei ca. 150 bis 170 Grad Celsius arbeitet. Bei solchen Vorrichtungen ist es wichtig, die Transparentfolie nicht zu beschädigen, da sie Temperaturen bis nur 90 Grad Celsius ertragen kann. Aus diesem Grund wird der Kleberstrei¬ fen gemäss dem Stand der Technik regelmässig auf den Karton, der viel höhere Temperaturen ertragen kann, aufgelegt.Devices are known which have a nozzle head for attaching an adhesive strip to an edge of a cardboard, onto which an edge of a transparent film is subsequently pressed, in order thereby to provide an adhesive connection, also called a hot-melt seam, between the cardboard and the transparent film , especially for the production of pencil cases. The adhesive strip is a so-called "hot glue" or PS glue that works at approx. 150 to 170 degrees Celsius. With such devices, it is important not to damage the transparent film, since it can withstand temperatures up to only 90 degrees Celsius. For this reason, the adhesive strip according to the prior art is regularly placed on the cardboard, which can withstand much higher temperatures.

Bei den eingangs erwähnten Vorrichtungen stellt sich nun das Problem, eine Heissleimnaht zwischen einem Karton und einer Transparentfolie herzustellen, die eine solidere Klebverbin¬ dung ergibt.In the devices mentioned at the outset, the problem now arises of producing a hotmelt seam between a cardboard box and a transparent film, which results in a more solid adhesive bond.

Diese Aufgabe wird erfindungsgemäss durch eine Vorrichtung mit den im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmalen gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben. Im folgenden wird die Erfindung beispielsweise anhand einer Zeichnung näher erläutert. Es zeigt:This object is achieved according to the invention by a device with the features specified in the characterizing part of claim 1. Further advantageous embodiments of the invention are specified in the dependent claims. The invention is explained in more detail below, for example, using a drawing. It shows:

Fig. 1 eine schematische Darstellung einer erfindungsgemässen Vorrichtung, undFig. 1 is a schematic representation of an inventive device, and

Fig. 2 eine schematische Darstellung der Heissleimnaht zwischen einer Transparentfolie und einem Karton.Fig. 2 is a schematic representation of the hot glue seam between a transparent film and a box.

Die Vorrichtung nach Fig. 1 weist je eine Vorratsrolle VRT und VRK für die Transparentfolie T (Fig. 2) bzw. für den Karton K auf. Zur Vereinfachung der Zeichnung sind in Fig. 1 die Achsen der Vorratsrollen VRT und VRK, die von einem gemeinsamen Träger TR gehaltert werden können, parallel verlaufend dargestellt. Für den Zweck der Erfindung können sie jedoch ohne weiteres in einem Winkel oder senkrecht zueinander angeordnet sein. Die Vorrichtung ist mit einem Mechanismus versehen, um zu bewirken, dass ab einer bestimmten Stelle die Transparentfolienbahn Tf in einem kleinen Abstand oberhalb der Kartonbahn Kb verläuft. Die Transparentfolienbahn Tf wird zu diesem Zweck mit Hilfe von Rollern Rl, R2, R3 und R4 derart geführt, dass ab dem Roller R4 sie tatsächlich nur in einem kleinen Abstand oberhalb der Kartonbahn Kb läuft. Die Kartonbahn Kb geht vorzugsweise zuerst über eine Rillstation VS vorbei, die im Fall gemäss Fig. 1 beispielsweise durch drei Rillrollerpaare schematisch angedeu¬ tet ist, die zur Herstellung von Rillen RL1 und RL2 (Fig. 2) dienen, die das nachträgliche Falten des Kartonrands erleich¬ tern. Solche Rillstationen sind an sich bekannt und werden daher nicht näher beschrieben.The device according to FIG. 1 has a supply roll VRT and VRK for the transparent film T (FIG. 2) or for the cardboard K. To simplify the drawing, the axes of the supply rolls VRT and VRK, which can be held by a common carrier TR, are shown running in parallel in FIG. 1. For the purpose of the invention, however, they can easily be arranged at an angle or perpendicular to one another. The device is provided with a mechanism for causing the transparent film web Tf to run a small distance above the cardboard web Kb from a certain point. For this purpose, the transparent film web Tf is guided with the aid of rollers R1, R2, R3 and R4 in such a way that it actually runs only a small distance above the cardboard web Kb from the roller R4. The cardboard web Kb preferably first passes over a creasing station VS, which in the case of FIG. 1 is schematically indicated, for example, by three creasing roller pairs which are used to produce grooves RL1 and RL2 (FIG. 2), which subsequently fold the carton edge lighten. Such creasing stations are known per se and are therefore not described in detail.

Obwohl die Achsen der Vorratsrollen VRT und VRK parallel dargestellt sind, befinden sich die eigentlichen Vorratsrollen VRT und VRK in verschobener Lage zueinander, so dass sie sich nur in einem relativ schmalen Rand überlappen, wo sie mitein¬ ander versiegelt werden. Im Bereich des Rollers R3 befindet sich die Mündung eines mit einem Behälter BK für einen heissen flüssigen Klebstoff verbundenen Düsenkopfes DK, mit dessen Hilfe ein Heissleim- oder Kleberstreifen KB (Fig. 2) auf die Transparentfolienbahn Tf aufgetragen wird, und zwar auf der Seite der Transparentfolie T, die später in Berührung mit der Kartonbahn Kb kommen soll, das heisst vorzugsweise ausserhalb der in Fig. 2 dargestellten Verrillung RLl, RL2. Dabei ist der Abstand zwischen den Rollern R3 und R4 relativ klein und die Geschwindigkeit der Folienbahnen relativ gross gewählt, damit die Transparentfolie T durch die hohe Temperatur des Heisskle- bers oder PS-Klebers nicht beschädigt wird, die bei den heute handelsüblichen Klebstoffen im Bereich von etwa 150 bis 170 Grad Celsius liegt, wobei zum Zweck der Erfindung diese Temperaturgrenzen nicht sehr relevant sind. Bei der erfindungs¬ gemässen Vorrichtung ist zudem eine Rollerpresse RP relativ nahe zum Roller R4 vorgesehen, um durch ein schnelles Zusammen¬ pressen der zwei Bahnen eine Beschädigung der Transparentfolie T zu vermeiden.Although the axes of the supply rolls VRT and VRK are shown in parallel, the actual supply rolls VRT and VRK are in a displaced position with respect to one another, so that they only overlap in a relatively narrow edge, where they are sealed together. Located in the area of the scooter R3 the mouth of a nozzle head DK connected to a container BK for a hot liquid adhesive, with the aid of which a hot glue or adhesive strip KB (FIG. 2) is applied to the transparent film web Tf, namely on the side of the transparent film T, which later in Should come into contact with the cardboard web Kb, that is, preferably outside of the grooving RL1, RL2 shown in FIG. 2. The distance between the rollers R3 and R4 is relatively small and the speed of the film webs chosen to be relatively high, so that the transparent film T is not damaged by the high temperature of the hot glue or PS glue, which in the range of adhesives currently available on the market is about 150 to 170 degrees Celsius, these temperature limits are not very relevant for the purpose of the invention. In the device according to the invention, a roller press RP is also provided relatively close to the roller R4 in order to avoid damage to the transparent film T by quickly pressing the two webs together.

Die Vorrichtung nach Fig. 1 umfasst zudem vorzugsweise einen nach der Rollerpresse RP angeordneten Mechanismus WM, der vorgesehen ist, um in den Bereich zwischen den zwei parallel verlaufenden Rillen RLl und RL2 und gegebenenfalls auch um diese Rillen (Fig. 2) einen weiteren Heissleimstreifen HS aufzutragen, ferner einen Abschneidemechanismus SM, um nachträglich die bereits mit einer Siegelnaht versehene Bahn in den gewünschten Längen zu schneiden, sowie einen Mechanismus FM zur Faltung der bereits gefalteten Mäppchen, während die Heissleimnaht KB, auch Kleberstreifen genannt, noch warm ist. Die Mechanismen WM und SM können in ein und dieselbe Einheit integriert sein.The device according to FIG. 1 also preferably comprises a mechanism WM arranged after the roller press RP, which mechanism is provided in order to insert a further hotmelt strip HS into the area between the two parallel grooves RL1 and RL2 and optionally also around these grooves (FIG. 2) apply, also a cutting mechanism SM to subsequently cut the web already provided with a sealing seam in the desired lengths, and a mechanism FM for folding the already folded pencil case, while the hot glue seam KB, also called adhesive strip, is still warm. The mechanisms WM and SM can be integrated in one and the same unit.

Durch die Erfindung wurde überraschenderweise festgestellt, dass die Transparentfolie T, beispielsweise eine sogenannte PVC-Folie oder eine Acetatfolie oder eine Folie aus Polypropy- len oder aus Polyester, viel besser als erwartet die erwähn¬ ten hohen Temperaturen widerstehen kann und dass die Versiege¬ lung zwischen der Tansparentfolie T und dem Karton Kb viel solider als bei den Mäppchen ist, die mit Hilfe anderer bekannter Vorrichtungen hergestellt werden. The invention surprisingly found that the transparent film T, for example a so-called PVC film or an acetate film or a film made of polypropylene, len or made of polyester, can withstand the high temperatures mentioned much better than expected and that the sealing between the transparent film T and the cardboard Kb is much more solid than with the pencil cases which are produced with the aid of other known devices.
