Abstract

The hot glueing of cardboard blanks formed around groups of packages requires precise adjustment and control of the glue aggregates. In such packages bottles, cans, glasses etc. soiled by faulty sprayings are often seen. When production is interrupted the glue is often completely missing or misses the glueing points. The intention of the following invention is to eliminate such disadvantages. Each cardboard blank has, at the points to be joined, an application of hot-melt adhesive already applied at the manufacturers. This application is activated in the folding process by, for example, hot-air nozzles or contact heating elements, in such a manner that it is capable of adhering. Subsequent pressing results in joining as usual. The anticipated advantages: More simple machines without glue aggregates and nozzles. No preheating of the glue. No complicated adjusting and control. Sufficient metering for the required strength. No spraying of the packaged goods or of the machines in error. The selection of the suitable adhesive is made by the manufacturer of the blank. The present invention facilitates, with increased safety, in particular the adhesive bonding of see-through or framed cardboard boxes for which particularly precise adhesive bonds are required.

Description

Das Verschließen oder Verbinden von Kartonagen nach dem Befüllen oder beim Einschlagen einer Warengruppe (wrap around) erfordert den Einsatz eines Heißleimaggregats mit den bekannten Heizschläuchen und Heizdüsen, der Kleber wird gespritzt. Die Einstellung derartiger Anlagen, ist entsprechend präzise und erfordert auch eine gewisse Anheizzeit. Die Pflege und Wartung solcher Anlagen ist zeitaufwendig. Das nachfolgend beschriebene Verfahren ist weder kompliziert noch teuer, noch bedarf es besonderer Präzision.The closing or joining of cardboard boxes after filling or when wrapping a product group (wrap around) requires the use of a hot melt unit with the known Hoses and heating nozzles, the glue is sprayed. The setting of such systems is correspondingly precise and also requires a certain heating time. The care and maintenance of such systems is time consuming. The procedure described below is neither complicated nor expensive, still requires special precision.

Die Neuerung betrifft das Vordrucken des Schmelzklebers an den, zu verbindenden Stellen, bereits bei der Herstellung der Pappzuschnitte. Beim Verpackungsvorgang werden diese Stellen einfach durch Wärme aktiviert und wie bisher angepreßt. Die Größe und Schichtstärke des Kleberaufdruckes bestimmen die Festigkeit der Verklebung.The innovation concerns the pre-printing of the hot melt adhesive on the connecting points, already during the production of the cardboard blanks. During the packaging process, these spots are simply exposed to heat activated and pressed as before. The size and layer thickness of the adhesive print determine the Bond strength.

Die Verpackungsmaschinen sind mit weniger Aufwand und mit größerer Sicherheit zu betreiben. Wartezeiten entfallen. Als Heizquellen für das Aktivieren sind Heißluftgebläse, Infrarot strahler oder Heizelemente aller Art berührungsfrei anwendbar.The packaging machines are with less To operate effort and with greater security. Waiting times are eliminated. Hot air blowers, infrared, are the heating sources for activation spotlights or heating elements of all types can be used without contact.

Die "Bedruckung" der Zuschnitte in der Herstellung, erfolgt mit Tauchrädern welche durch Niederdrücken der Zuschnitte an den betreffenden Stellen kontaktiert werden. So können Streifen, (durch mehrere schmale Räder) oder Flächen, durch breite Räder, erzielt werden. Auch das Anspritzen von Streifen kann angewendet werden, ist aber sicher aufwendiger. The "printing" of the blanks in the production takes place with Submersible bikes which by pressing the blanks on the relevant positions can be contacted. So stripes, (by several narrow wheels) or surfaces, through wide wheels. The spraying of strips can also be used, but is certainly more complex.  

Darstellung.Presentation.

Auf dem nachfolgenden Blatt sind die Punkte Nr. 1., bis Nr. 5., vereinfacht dargestellt.On the following sheet, points No. 1 to No. 5 are shown in simplified form.

Nr. 1., ist ein möglicher Schmelzkleberaufdruck in Streifenform auf der Innenklappe eines Pappezuschnittes.No. 1 , is a possible hot melt adhesive print in strip form on the inner flap of a cardboard blank.

Dieser selbst ist Nr. 3., beziffert.This itself is number 3 .

Die untere Figur zeigt den Faltvorgang beim Einschlagen. (Nr. 4.,)The lower figure shows the folding process when wrapping. (No. 4. ,)

Die noch offenen Klappen zeigen auf der Innenseite die, durch die Heizung Nr. 2., aktivierten Schmelzkleberstreifen, kurz vor dem Anpressen Nr. 5.,The flaps that are still open show on the inside the hot-melt adhesive strips activated by heating no. 2 , shortly before pressing no. 5 .

Dies erfolgt nach Verlassen der Heizzone.This takes place after leaving the heating zone.

Der aufgerichtete Karton ist mit Nr. 4., dargestellt.The erected carton is shown with number 4 .
