Description

Die Erfindung betrifft ein Leimwerk für eine Bodenlegevorrichtung für Kreuzbodensäcke gemäß des Oberbegriffs des Anspruchs 1.The invention relates to a gluing unit for a bottom-laying device for cross-bottom sacks according to the preamble of claim 1.

In einem Leimwerk einer Bodenlegevorrichtung werden das aufgezogene Ende oder die aufgezogenen Enden und die dadurch gebildeten Eckeinschläge eines Schlauchabschnitts aus Papier, Kunststoff oder anderem geeignetem Material mit Leim beaufschlagt, um anschließend durch Zulegen der aufgezogenen Enden auf die Eckeinschläge einen dauerhaft verklebten Sackboden zu erhalten.In a gluing unit of a floor laying device, the mounted end or ends and the corner folds of a hose section made of paper, plastic or other suitable material are applied with glue in order subsequently to obtain a permanently glued bag bottom by placing the drawn ends on the corner strikes.

Ein typischerweise verwendetes Leimwerk einer Bodenlegevorrichtung gemäß dem Oberbegriff des Anspruchs 1 ist beispielsweise in der Patentschrift DE 196 34 594 C2 dargestellt. In einer Tragplatte sind eine Dosier- und eine Leimauftragswalze gelagert, die zusammen mit einem Gehäuse ein geschlossenes System, in dem eine Leimsäule gewünschter Höhe gehalten wird, bilden. Der Leim wird von der Leimauftragswalze auf die Klischeewalze übertragen, wobei die zu übertragende Leimmenge durch eine passende Wahl des Abstandes der Dosier- und der Leimauftragswalze eingestellt wird. Die Klischeewalze überträgt den Leim auf das zu beleimende Werkstück. Das geschlossene System bietet den Vorteil, dass der Leim gleichmäßig aufgetragen wird und die Dosierung sehr feinfühlig eingestellt werden kann. Zudem kann kein Leim an die Umgebung des Leimwerks abgegeben werden, wodurch Verschmutzungen und unnötiger Leimverbrauch verursacht werden.A typically used gluing of a Bodenlegevorrichtung according to the preamble of claim 1 is for example in the Patent DE 196 34 594 C2 shown. In a support plate, a metering and a glue applicator roller are mounted, which together with a housing form a closed system in which a glue column of desired height is held. The glue is transferred from the glue application roller to the plate roller, wherein the amount of glue to be transferred is adjusted by a suitable choice of the distance of the metering and the glue applicator roller. The cliché roller transfers the glue to the workpiece to be glued. The closed system offers the advantage that the glue is applied evenly and the dosage can be adjusted very sensitively. In addition, no glue can be released to the surroundings of the gluing unit, which causes soiling and unnecessary glue consumption.

In anderen bekannten Leimwerken wird ein offenes System verwendet. Hierbei handelt es sich im Prinzip um das zuvor beschriebene Leimwerk, jedoch anstelle eines als Leimreservoir dienenden Gehäuses wird lediglich eine Düse als Leimquelle eingesetzt. Diese Düse ist auf der der Klischeewalze abgewandten Seite des Spalts zwischen der Dosier- und der Leimübertragungswalze angebracht. In einem solchen Leimwerk müssen die Walzen senkrecht angeordnet sein, wobei die Düse den Leim am oberen Ende der Dosierwalze auf deren Außenumfang aufträgt. Durch die Gravitation und die Rotation der Dosierwalze verteilt sich der Leim auf die gesamte Oberfläche. Von der Dosierwalze wird der Leim über die Leimauftragswalze und die Klischeewalze dem Werkstück zugeführt. Dem offenen System werden Vorteile bei der Verwendung bestimmter Leimsorten nachgesagt. Durch die kurze Verweildauer des Leims in einem offenen System - die Verwendung dieses Systems führt zu hohen Leimverlusten - kann dieser nur wenig Lösemittel abgeben und neigt daher nicht zum Antrocknen.In other known gluing plants an open system is used. This is in principle the gluing unit described above, but instead of serving as a glue reservoir housing only one nozzle is used as a glue source. This nozzle is mounted on the side facing away from the cliché roll of the gap between the metering and the glue transfer roller. In such a gluing unit, the rollers must be arranged vertically, with the nozzle applying the glue to the upper end of the metering roller on its outer circumference. Due to the gravity and the rotation of the metering roller, the glue spreads over the entire surface. From the metering roller, the glue is fed to the workpiece via the glue application roller and the cliché roller. The open system is said to benefit from the use of certain types of glue. Due to the short residence time of the glue in an open system - the use of this system leads to high glue losses - this can give off very little solvent and therefore does not tend to dry.

Daher besteht die Aufgabe der Erfindung darin, eine Vorrichtung bereitzustellen, welche die Vorteile beider Beleimungseinrichtungen in sich vereint und kostengünstig bereitzustellen ist.Therefore, the object of the invention is to provide a device which combines the advantages of both Beleimungseinrichtungen in itself and is inexpensive to provide.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst.According to the invention, this object is solved by the features of the characterizing part of claim 1.

Demnach ist die Dosierwalze zumindest sequentiell sowohl in Kontakt mit einer Leimquelle als auch mit einem Leimreservoir bringbar. In einem derartigen Leimwerk können nahezu alle Leimsorten, die für die Herstellung von Kreuzbodensäcken Anwendung finden, verarbeitet werden. Geeignete Leimsorten können in dem Leimreservoir gehalten werden, wohingegen solche Leimsorten, die eine Verarbeitung aus einem Leimreservoir nicht zulassen, über eine Düse auf die Dosierwalze aufgebracht werden.Accordingly, the metering roller can be brought into contact, at least sequentially, both with a glue source and with a glue reservoir. In such a gluing plant, almost all types of glue which are used for the production of cross-soil sacks can be processed. Suitable types of glue can be held in the glue reservoir, whereas those types of glue that do not allow processing from a glue reservoir are applied to the metering roll via a nozzle.

Es ist dabei besonders vorteilhaft, wenn die Drehrichtung der Dosierwalze umkehrbar ist. In einem geschlossenen System hat die Dosierwalze gewöhnlich den gleichen Drehsinn wie die Leimübertragungswalze, um so einen ungewollten Leimaustritt aus dem Reservoir zu verhindern. In einem offenen System sollte die Dosierwalze jedoch zum Zwecke eines optimalen Leimübertrags einen im Vergleich zur Leimübertragungswalze entgegen gesetzten Drehsinn haben.It is particularly advantageous if the direction of rotation of the metering roller is reversible. In a closed system, the metering roller usually has the same sense of rotation as the glue transfer roller so as to prevent unwanted glue leakage from the reservoir. However, in an open system, the dosing roller should have a direction of rotation opposite to that of the size transfer roller for optimum glue transfer.

Für eine einfache Drehrichtungsumkehr verfügt vorteilhafterweise zumindest eine der vorgenannten Walzen über einen eigenen Antriebsmotor.For a simple reversal of rotation, advantageously at least one of the aforementioned rollers has its own drive motor.

Vorteilhaft ist es auch, dass zumindest eine der vorgenannten Walzen über einen eigenen Elektromotor verfügt, welcher von einem leistungselektronischen Leistungsstelle mit Strom versorgt wird.It is also advantageous that at least one of the aforementioned rollers has its own electric motor which is supplied with power by a power-electronic power point.

In einer besonders bevorzugten Ausgestaltung der Erfindung ist diese Walze die Dosierwalze.In a particularly preferred embodiment of the invention, this roller is the metering roller.

Fig. 1 zeigt ein Leimwerk einer Bodenlegevorrichtung mit einem geschlossenen Leimauftragssystem. Der Leim 9 befindet sich in einem Leimtank 1. Der Leimtank ist ebenso wie die Walzen 2, 3 und 4 in einer nicht dargestellten Tragplatte befestigt. Die Seitenwände des Leimtanks 9 stehen in Kontakt mit der Dosierwalze 2 und der Leimauftragswalze 3, so dass an diesen Kontaktflächen kein Leim entweichen kann. Der Leim 9 wird von der Leimauftragswalze 3 mitgenommen und kann den einstellbaren Spalt zwischen der Dosierwalze 2 und der Leimauftragswalze 3 passieren. Die Drehrichtungen B und C der Dosierwalze 2 und der Leimauftragswalze 3 sind gleichsinnig. Die gezeigte Drehrichtung C verhindert, dass auch die Dosierwalze 2 Leim 9 aus dem Leimtank 1 transportiert. Weitere Details bezüglich der Lagerung der Walzen 2, 3 und der Befestigung des Leimtanks 1 sind in der Patentschrift DE 196 34 594 C2 beschrieben. Fig. 1 shows a Glueing a Bodenlegevorrichtung with a closed glue application system. The glue 9 is located in a glue tank 1. The glue tank is just like the rollers 2, 3 and 4 fixed in a support plate, not shown. The side walls of the glue tank 9 are in contact with the metering roller 2 and the glue application roller 3, so that at this Contact surfaces no glue can escape. The glue 9 is taken away by the glue application roller 3 and can pass through the adjustable gap between the metering roller 2 and the glue application roller 3. The directions of rotation B and C of the metering roller 2 and the glue application roller 3 are in the same direction. The direction of rotation C shown prevents the metering roller 2 glue 9 from being transported from the glue tank 1. Further details regarding the storage of the rollers 2, 3 and the attachment of the glue tank 1 are in the Patent DE 196 34 594 C2 described.

Fig. 2 zeigt das gleiche Leimwerk in der Betriebsweise als offenes Leimauftragssystem. Um das Leimwerk auf diese Betriebsart vorzubereiten, wird der Leimtank 1 demontiert und eine Leimdüse 5 auf nicht gezeigte Weise an der Tragplatte befestigt. Zum Betrieb des offenen Leimwerks behalten die Leimauftragswalze 3 und die Klischeewalze 4 ihren Drehsinn bei. Der Drehsinn der Dosierwalze ist im Vergleich zur geschlossenen Betriebsweise umgekehrt. Der Leim wird über eine Zuführleitung 6 der Leimdüse 5 zugeführt, die am oberen Ende der Dosierwalze 2 angeordnet ist. Die Leimdüse 5 trägt den Leim auf die Dosierwalze auf. Der Leim wird auf die Leimauftragswalze 3 übertragen und gelangt anschließend auf die Klischeewalze, die den Leim an das zu beleimende Werkstück abgibt. Unterhalb der Dosierwalze 2 und der Klischeewalze 3 ist eine Leimwanne 7 angeordnet, die den von den Walzen abgetropften und abgeschleuderten Leim auffängt und über einen Abfluss 8 abführt. Fig. 2 shows the same gluing unit in the mode of operation as an open glue application system. In order to prepare the gluing unit for this operating mode, the glue tank 1 is dismantled and a glue nozzle 5 is fastened to the support plate in a manner not shown. To operate the open gluing unit, the glue application roller 3 and the plate roller 4 maintain their sense of rotation. The direction of rotation of the metering roller is reversed compared to the closed mode of operation. The glue is fed via a feed line 6 of the glue nozzle 5, which is arranged at the upper end of the metering roller 2. The glue nozzle 5 applies the glue to the metering roller. The glue is transferred to the glue application roller 3 and then passes to the plate roller, which delivers the glue to the workpiece to be glued. Below the metering roller 2 and the cliché roller 3 a glue trough 7 is arranged, which catches the glue drained and spun off by the rollers and removes them via a drain 8.

Fig. 3 zeigt ein geschlossenes Leimwerk gemäß Schnitt III - III in Fig. 1. Die Walzen 2, 3, sind mit ihren Walzenachsen 13 einendig und drehbar in der Tragplatte 10 gelagert. Die Tragplatte ist auf nicht näher dargestellte Weise mit dem Maschinengestell verbunden. Die Walzenachsen 13 können durch aufgesetzte Antriebe, etwa Zahnriemenscheiben, auf denen ein Zahnriemen läuft, angetrieben werden. An dem Leimtank sind zwei Bolzen 11 fest angebracht, die durch zwei Durchgangsbohrungen in der Tragplatte 10 gesteckt werden können. Oberhalb der Tragplatte sind die Bolzen, die zumindest an ihrem oberen Ende Gewinde aufweisen, mit Muttern 12, beispielsweise Rändelmuttern, gesichert. Auf diese Weise kann der Leimtank 1 auf einfache Weise an der Tragplatte 10 befestigt werden oder von dieser entfernt werden. Fig. 3 shows a closed gluing unit according to section III - III in Fig. 1 , The rollers 2, 3 are mounted with their roller axes 13 in one end and rotatably in the support plate 10. The support plate is connected in a manner not shown with the machine frame. The roller axles 13 can be driven by attached drives, such as toothed belt pulleys, on which a toothed belt runs. At the glue tank two bolts 11 are fixedly mounted, which can be inserted through two through holes in the support plate 10. Above the support plate are the bolts that at least at its upper end threaded, with nuts 12, such as knurled nuts, secured. In this way, the glue tank 1 can be easily attached to the support plate 10 or removed therefrom.

Die Fig. 4 zeigt ein offenes Leimwerk gemäß Schnitt IV - IV in Fig. 2. Nach dem Entfernen des Leimtanks 1 kann durch eine der Durchgangsbohrungen in der Tragplatte 10 ein Bolzen 11 gesteckt werden, an welchem die Leimdüse 5 befestigt ist. Der Bolzen 11 wird durch eine Mutter 12, die oberhalb der Tragplatte auf den Bolzen 11 geschraubt wird, gegen Herausfallen gesichert. Unterhalb der Tragplatte 10 kann zur Höhenjustage eine weitere Mutter 12 auf den Bolzen 11 aufgeschraubt sein.
