Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Aufbringen von formatmäßigen Klebstoffaufträgen auf eine Übertragungswalze, die ihre Klebstoffaufträge durch Abwälzen auf kontinuierlich geförderte zu beleimende Werkstücke abgibt.The invention relates to a device for applying format adhesive orders on a transfer roller, which their adhesive orders by rolling on continuously conveyed workpieces to be glued.
Derartige Klebstoffauftragsvorrichtungen sind in unterschiedlichen Ausführungsformen bekannt. Sie bestehen üblicherweise (siehe z.B. DE 196 34 594 A1) aus einer oder zwei an die Öffnungskanten eines eine Klebstoffkammer umschließenden Gehäuses angestellten und dieses verschließenden Klebstoffwalzen, die ihre Klebstoffaufträge an eine Übertragungswalze abgeben. Die Übertragungswalze kann dabei nahezu vollflächig mit Klebstoffaufträgen versehen werden oder aber mit Klischees versehen sein, die entsprechend ihrer Form formatmäßige Klebstoffaufträge übernehmen und übertragen. Der Nachteil derartiger bekannter Klebstoffauftragsvorrichtungen besteht darin, daß bei einer Änderung des oder der Formate der Klebstoffaufträge die die Klischees tragende Übertragungswalze ausgetauscht werden muß. Weiterhin läßt sich bei den bekannten Klebstoffauftragsvorrichtungen nicht vermeiden, daß aus diesen ständig Klebstoff austritt, aufgefangen und abgeleitet oder zurückgeleitet werden muß. Weiterhin ist die Reinigung der bekannten Klebstoffauftragsvorrichtungen, die regelmäßig erfolgen muß, zeitaufwendig.Such adhesive application devices are in different embodiments known. They usually consist (see e.g. DE 196 34 594 A1) of one or two to the opening edges of a housing enclosing an adhesive chamber employed and this sealing glue rollers that do their glue jobs deliver to a transfer roller. The transfer roller can can be provided with adhesive applications almost over the entire surface or with clichés be provided, the format adhesive orders according to their shape take over and transfer. The disadvantage of such known adhesive application devices consists in the fact that when changing the format or formats of the Glue jobs exchanged the transfer roller carrying the clichés must become. Furthermore, in the known adhesive application devices do not prevent glue from constantly escaping, collecting and draining or must be returned. Furthermore, the cleaning of the known Adhesive applicators, which must be done regularly, are time consuming.
Aufgabe der Erfindung ist es daher, eine Klebstoffauftragsvorrichtung der eingangs angegebenen Art zu schaffen, die eine einfache und schnelle Änderung der zu übertragenden Klebstoffformate ermöglicht und zudem bei einfachem Aufbau sauber und nahezu wartungsfrei arbeitet.The object of the invention is therefore to provide an adhesive application device at the outset specified type to create a simple and quick change to transferred adhesive formats and also clean with a simple structure and works almost maintenance-free.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß neben der Übertragungswalze Klebstoffdüsen in gleichen axialen Abständen angeordnet sind, die gegen den Mantel der Übertragungswalze gerichtet und mit Verschlüssen versehen sind, die einzeln jeweils zu ihrer Öffnung und ihrem Verschluß von einer Steuereinrichtung gesteuert sind.According to the invention this object is achieved in that in addition to the transfer roller Adhesive nozzles are arranged at equal axial intervals that directed against the jacket of the transfer roller and provided with closures are, each individually to their opening and their closure by a control device are controlled.
Mit der erfindungsgemäßen Klebstoffauftragsvorrichtung lassen sich durch entsprechende Steuerung der Klebstoffdüsen beliebige Formate von Klebstoffaufträgen auf die Übertragungswalze aufsprühen. Ist die Vorrichtung derart eingestellt, daß die aufgesprühten Klebstoffaufträge von den Werkstücken vollständig von der Übertragungswalze abgenommen werden, ist ein sauberer und nahezu wartungsfreier Betrieb möglich.With the adhesive application device according to the invention can be by appropriate Control of the adhesive nozzles on any formats of adhesive orders spray on the transfer roller. Is the device set so that the sprayed adhesive orders from the workpieces completely from the transfer roller removed, is a clean and almost maintenance-free operation possible.
Nebeneinander angeordnete Klebstoffauftragsdüsen vermögen möglicherweise auch dann keinen durchgehenden Klebstoffauftrag, also einen Klebstoffauftrag, der nicht aus nebeneinander liegenden Streifen besteht, aufzutragen, wenn die auf die Übertragungswalze aufgesprühten streifenförmigen Klebstoffaufträge beim Übertragen auf die zu beleimenden Werkstücke, beispielsweise eine durchlaufende Bahn, breitgedrückt werden. In weiterer Ausgestaltung der Erfindung ist daher vorgesehen, daß eine Reihe von Klebstoffdüsen an einem Träger gehaltert ist, der durch eine Steuereinrichtung die Reihe parallel zur Achse der Übertragungswalze verschiebt. Die Klebstoffdüsen können dabei entsprechend dem auf der Übertragungswalze zu erzeugenden Format so gesteuert werden, daß bei jedem Umlauf jede der für das zu erzeugende Format in Betrieb befindlichen Klebstoffdüsen einen Umfangsstreifen der erforderlichen Länge auf die Übertragungswalze aufträgt und bei dem nachfolgenden Umlauf eine Verstellung in axialer Richtung in der Weise erfolgt, daß der folgende Klebstoffauftrag zwischen die zuvor erzeugten Klebstoffaufträge aufgebracht wird. Bei dieser Betriebsweise kann davon ausgegangen werden, daß die Übertragungswalze bei jedem Umlauf nur einen Teil der aufgesprühten Klebstoffstreifen an die vorbeilaufende Bahn oder die vorbeilaufenden Werkstücke abgibt, so daß immer vollflächige, den Formaten entsprechende Klebstoffübertragungen erfolgen.Adjacent dispensing nozzles may be able to even then no continuous adhesive application, i.e. an adhesive application that does not consist of strips lying next to one another, if the on the Transfer roller sprayed strip-shaped adhesive applications during transfer on the workpieces to be glued, for example a continuous one Web, be pushed broadly. In a further embodiment of the invention it is therefore provided that that a series of adhesive nozzles is held on a carrier which by a control device the row parallel to the axis of the transfer roller shifts. The adhesive nozzles can correspond to that on the transfer roller Format to be generated are controlled so that with each circulation each of the adhesive nozzles in operation for the format to be produced has one Applies circumferential strips of the required length on the transfer roller and in the subsequent rotation an adjustment in the axial direction in the way it follows that the following adhesive application between the previously generated adhesive orders is applied. This mode of operation can be assumed be that the transfer roller sprayed only a portion of the spray on each revolution Adhesive strips on the passing web or the passing ones Releases workpieces, so that there are always full-surface adhesive transfers corresponding to the formats respectively.
Zweckmäßigerweise weisen die Klebstoffdüsen jeweils einen Abstand voneinander auf, der der doppelten Breite der jeweils von diesen aufzutragenden Klebstoffspur entspricht, wobei die Klebstoffdüsen im Takt einer Umdrehung der Übertragungswalze jeweils um die Breite einer Klebstoffspur hin- und herverschieblich sind. Bei dieser Betriebsweise wird also jede Klebstoffspur nur bei jedem zweiten Umlauf der Übertragungswalze gelegt, so daß sich entsprechend der Anzahl der in Betrieb befindlichen Klebstoffdüsen und der durch entsprechende Steuerung erzeugten Umfangslängen der Klebstoffspuren beliebige vollflächige zu übertragende Klebstoffaufträge auf die Übertragungwalze aufbringen lassen.The adhesive nozzles are expediently spaced apart from one another on, twice the width of the adhesive track to be applied by these corresponds, with the adhesive nozzles in time with one revolution of the transfer roller are slidable back and forth around the width of an adhesive track. at In this mode of operation, every trace of adhesive is only removed every second time Transfer roller placed so that according to the number of in operation Adhesive nozzles and the circumferential lengths generated by appropriate control any traces of adhesive to be transferred across the entire surface have it applied to the transfer roller.
Die Anordnung der Klebstoffdüsen in einem entsprechenden Abstand voneinander trägt auch dem Umstand Rechnung, daß die Klebstoffdüsen sehr teuer sind, so daß selbst zum Auftrag von formatgerechten vollflächigen Klebstoffaufträgen nur eine entsprechend verringerte Anzahl von Klebstoffdüsen erforderlich ist.The arrangement of the adhesive nozzles at a corresponding distance from one another also takes into account the fact that the adhesive nozzles are very expensive, so that even for the application of format-compliant full-surface adhesive applications only one a correspondingly reduced number of adhesive nozzles is required.
Soll zu Beginn des Betriebes kein Ausschuß in der Weise produziert werden, daß der erste Auftrag nicht vollflächig, sondern nur streifenmäßig erfolgt, kann die Steuerung in der Weise erfolgen, daß durch zwei Umdrehungen der Übertragungswalze ein vollflächiger formatgerechter Klebstoffauftrag erfolgt, bevor dieser von durchlaufenden Bahnen oder Werkstücken abgenommen wird.At the beginning of the operation, no committee should be produced in such a way that the first application is not complete, but only in strips Control in such a way that by two revolutions of the transfer roller a full-surface format-compliant adhesive application is carried out before this from continuous webs or workpieces is removed.
Es ist auch möglich, die Klebstoffaufträge durch ein anderes Streifenmuster vollflächig aufzubringen. Aus diesem Grunde ist nach einer weiteren Ausführungsform vorgesehen, daß die Klebstoffdüsen jeweils einen Abstand von einem Mehrfachen der Breite der jeweils von diesen aufzutragenden Klebstoffspuren aufweisen und in einer Anzahl von diesen mehrfachen entsprechenden Schritten im Takt der Umdrehungen der Übertragungswalze jeweils um die Breite einer Klebstoffspur hin und vorzugsweise in einem Schritt zurück beweglich sind.It is also possible to apply the adhesive over the entire surface using a different stripe pattern applied. For this reason, according to another embodiment provided that the adhesive nozzles are each a distance of a multiple the width of the adhesive traces to be applied by them and in a number of these multiple corresponding steps in time with the revolutions the transfer roller each around the width of an adhesive track and are preferably movable back in one step.
Die Steuerung der Klebstoffdüsen besteht zweckmäßigerweise aus einer Mikrocomputersteuerung. Die Bilder der formatmäßigen Klebstoffaufträge können in einem Speicher (bit map) eines entsprechenden Rechners abgelegt sein, der die Öffnungs- und Schließzeitpunkte der Klebstoffauftragsdüsen zum formatgerechten Auftrag steuert.The control of the adhesive nozzles expediently consists of a microcomputer control. The pictures of the format adhesive orders can be in one Memory (bit map) of a corresponding computer which stores the opening and closing times of the adhesive application nozzles for the correct format Order controls.
Nach einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß die Klebstoffdüsen an einem langgestreckten Träger gehaltert sind, der in Führungen des Maschinengestells durch eine Antriebseinrichtung, z.B. eine Druckmittelkolbenzylindereinheit, im Takt der Umdrehung der Übertragungswalze schrittweise in beide Richtungen verschieblich ist. Mit dieser Verschiebeeinrichtung läßt sich das Muster der bei aufeinanderfolgenden Drehungen erzeugten Klebstoffspuren steuern.According to a preferred embodiment of the invention it is provided that the Adhesive nozzles are held on an elongated carrier, which is in guides the machine frame by a drive device, e.g. a pressure medium piston cylinder unit, in step with the rotation of the transfer roller in both Directions is shiftable. With this shifting device, the pattern can be control the glue traces generated during successive rotations.

versehen sein kann. Zwischen der Klebstoffübertragungswalze 2 und der Gegendruckwalze
3 läuft eine mit formatmäßigen Klebstoffaufträgen zu versehene Bahn
oder in vorbestimmten Abständen geförderte zu beleimende Werkstücke 4 hindurch.
Die Werkstücke 4 werden in Richtung des Pfeils durch geeignete Fördereinrichtungen,
beispielsweise Bandförderer, gefördert.The adhesive application device consists of a in a machine frame 1

Zu Beginn des Betriebes wird der aus Fig. 2 ersichtliche formatmäßige Klebstoffauftrag während zweier Umdrehungen aufgebracht. Anschließend werden in aufeinanderfolgenden Umdrehungen jeweils die Leimspuren a und b aufgebracht, so daß jedes durchlaufende zu beleimende Werkstück 4 eine frische Leimspur und den Rest einer bei der vorhergehenden Umdrehung aufgebrachten Leimspur übernimmt. Da bei jedem abwälzenden Auftrag das zu beleimende Werkstück von der Klebstoffübertragungswalze den Klebstoff nicht vollständig übernimmt, ist es zur Erzeugung eines vollflächigen formatmäßigen Leimauftrags auf den zu beleimenden Werkstücken ausreichend, die einzelnen Leimspuren nur in dem beschriebenen Wechsel aufzubringen.At the beginning of the operation, the format-type adhesive application shown in FIG. 2 is shown applied during two revolutions. Then be in successive Revolutions the glue traces a and b applied, see above that each continuous workpiece to be glued 4 a fresh glue trail and takes over the rest of a glue trace applied during the previous revolution. Since with every rolling job, the workpiece to be glued from the Adhesive transfer roller does not take over the adhesive completely, it is too Generation of a full-surface format glue application on the glue Workpieces sufficient, the individual traces of glue only in the described To bring change.
Für bestimmte Anwendungsfälle kann es ausreichend sein, nur formatmäßige Leimaufträge zu übertragen, die ein streifenförmiges Muster mit klebstofffreien Streifen zwischen den einzelnen Klebstoffspuren aufweisen. Sollen aber beispielsweise Böden von Säcken mit formatmäßigen Klebstoffaufträgen versehen werden, sind üblicherweise vollflächige Klebstoffaufträge erforderlich, um das Entstehend von Rieselkanälen zu vermeiden.For certain applications, it may be sufficient to apply only size-based glue to transfer which is a striped pattern with adhesive free strips between the individual traces of adhesive. But should, for example, floors sacking with format adhesive is common full-surface adhesive applications required to prevent the formation of trickle channels to avoid.
