Description

Die Erfindung betrifft eine neuartige Vorrichtung zur Querbeleimung von Druckprodukten, insbesondere in Rollenoffsettmaschinen, sowie ein entsprechendes Verfahren, wie z.B aus EP-A-0 096 832 bekannt.The invention relates to a novel device for transverse gluing of Printed products, in particular in Rollenoffsettmaschinen, and a corresponding method, such as known from EP-A-0 096 832.

Bekannt sind Walzenquerleimwerke mit einer Lochplatte, wobei die Löcher in einer Beleimposition über einen gemeinsamen Verschluß mechanisch geöffnet werden. Dieses System hat den Nachteil, daß es wegen des gemeinsamen Verschlusses für alle Löcher sehr verschmutzungsanfällig und wartungsintensiv ist. Weiterhin ist dieses System technisch aufwendig und folglich kostenintensiv. Darüber hinaus wird bei diesem System der Leim lediglich aus den Löchern herausgepreßt, was zusätzlich zu einer hohen Verschmutzung führt. Auch erfolgt bei diesem System ein Leimauftrag immer über die Gesamtlänge der Löcheranordnung.Are known Walzenquerleimwerke with a perforated plate, the holes in a Beleimposition via a common closure mechanically be opened. This system has the disadvantage that it is due to the common closure for all holes very susceptible to contamination and is maintenance intensive. Furthermore, this system is technically complex and consequently expensive. In addition, in this system, the glue just squeezed out of the holes, which in addition to a high Pollution leads. Also, this system is a glue application always over the total length of the hole arrangement.

Außerdem sind elektronisch gesteuerte Düsenquerleimwerke mit Einzelverschlüssen für jeweils eine Leimauftragseinrichtung bekannt. Derartige Düsenquerleimwerke sind jedoch statisch hinsichtlich des sich bewegenden Druckproduktes, so daß wegen der mechanischen und elektrischen Toleranzen der Auftragseinrichtungen sowie des Abrißverhaltens der Leimpunkte nur bis zu begrenzten Geschwindigkeiten ein zufriedenstellendes Auftragsbild erreicht werden kann. In addition, electronically controlled nozzle cross-glue units with individual closures for each a glue applicator known. such However, nozzle cross-lapping units are static in terms of moving Printed product, so that because of the mechanical and electrical Tolerances of the application equipment as well as the tear - off behavior of the Glue points only up to limited speeds satisfactory order image can be achieved.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung und ein Verfahren zur Querbeleimung von Druckprodukten bereitzustellen, bei welchem eine verhältnismäßig leichte Wartung bei gleichzeitig hoher Qualität des Leimauftrags gewährleistet ist.The object of the invention is a device and a To provide a method for cross gluing printed products, at which a relatively easy maintenance at the same time high Quality of the glue application is guaranteed.

Diese Aufgabe wird einerseits durch eine Vorrichtung zur Querbeleimung von Druckprodukten mit einzelnen Auftragseinrichtungen gemäß Anspruch 1, sowie ein Verfahren zur Querbeleimung von Druckprodukten gemäß Anspruch 7 gelöst.This object is achieved on the one hand by a device for transverse gluing of printed products with individual applicators according to claim 1, and a method for Querbeleimung of printed products according to claim 7 solved.

In vorliegendem Zusammenhang wird unter einzelnen Auftragseinrichtungen jedes mit Leim in Kontakt kommende Bauteil einer Auftragseinrichtung verstanden, welches einzeln, unabhängig von anderen Auftragseinrichtungen, von einer Walze, z.B. zu Wartungszwecken, entfernbar bzw. an dieser anbringbar ist. Insbesondere können dieses einzelne Düsen oder Düsenköpfe bzw. Düsenteile sein.In the present context is under individual applicators each component of an application device coming into contact with glue which individually, independently of other applicators, from a roller, e.g. for maintenance purposes, removable or attachable to this. In particular, these can be individual nozzles or nozzle heads or nozzle parts.

Um eine Wartung zu erleichtern, kann an der Walze zumindest eine auswechselbare Halterung für zumindest eine Auftragseinrichtung vorgesehen sein. Es ist auch denkbar, an einer Halterung mehrere einzelne Auftragseinrichtungen vorzusehen. Aus diesem Grunde kann an der Walze auch ein auswechselbares Modul vorgesehen sein, welches wenigstens zwei Halterungen aufweist. Durch eine derartige Anordnung läßt sich auch eine Reinigung sowie eine Anpassung an geänderte Anforderungen erleichtern. Hierdurch werden gleichzeitig die für derartige Arbeiten notwendige Standzeiten verkürzt, wodurch die Maschinenlaufzeit entsprechend vorteilhaft verlängert werden kann.To facilitate maintenance, at least one interchangeable Holder provided for at least one applicator be. It is also conceivable, on a holder several individual applicators provided. For this reason, on the roller can also be provided replaceable module, which at least two brackets having. By such an arrangement can also be a Cleaning and adaptation to changing requirements easier. As a result, at the same time necessary for such work Shelf life shortened, whereby the machine running time correspondingly advantageous can be extended.

Die Flexibilität der erfindungsgemäßen Anordnung läßt sich erhöhen, wenn die Auftragseinrichtungen einzeln ansteuerbar sind bzw. einzeln angesteuert werden. Hierdurch kann ohne bauliche Maßnahmen die Art und Weise des Leimauftrages jeder einzelnen Auftragseinrichtung sowie die Länge der Leimbahn angepaßt werden. Die einzelne Ansteuerung der Auftragseinrichtungen ermöglicht es insbesondere, daß die Auftragseinrichtungen durch eine gemeinsame Leimzufuhr mit Leim versorgt werden können, ohne daß auf die erfindungsgemäßen Vorteile verzichtet werden müßte.The flexibility of the arrangement according to the invention can be increased if the applicators can be controlled individually or controlled individually become. As a result, without structural measures, the manner of Glue orders of each individual order device as well as the length of the Glue path be adapted. The individual control of the application facilities allows in particular that the applicators can be supplied with glue by a common glue supply, without having to forego the advantages of the invention.

Je nach Anforderungen kann, auch um eine Ansteuerung nicht zu komplex werden zu lassen, eine blockweise bzw. gruppenweise Ansteuerung der einzelnen Auftragseinrichtungen vorgesehen sein.Depending on the requirements, it may not be too complex, even for a control to be a blockwise or groupwise control of be provided individual applicators.

Durch eine elektrische Ansteuerung wenigstens einer der Auftragseinrichtungen kann eine verhältnismäßig einfach zu realisierende und sehr flexible Ansteuerung gewährleistet werden.By an electrical control of at least one of Applicators can be relatively easy to implement and very flexible control can be ensured.

Die Verschmutzungsgefahr wird erfindungsgemäß vermindert, indem die Auftragseinrichtungen Leim auf das mit Leim zu versehene Druckprodukt spritzen. Dieses kann insbesondere durch Düsen geschehen. Werden die Düsen elektrisch angesteuert, läßt sich der Leimauftrag auf einfache Weise genau dosieren. Die Düsen können auch eine Pumpvorrichtung aufweisen, die entsprechend einer elektrischen Ansteuerung den Leim transportieren. Hierdurch kann eine besonders feine und fein abgestimmte Dosierung erfolgen.The risk of contamination is inventively reduced by the Applicators Glue on the glued printed product squirt. This can be done in particular by nozzles. Will the Nozzles electrically controlled, the glue application can be easily to dose exactly. The nozzles may also have a pumping device, which transport the glue according to an electrical control. This allows a particularly fine and finely tuned dosage respectively.

Zur Vermeidung von Verunreinigungen bringen die Düsen erfindungsgemäß den Leim berührungslos auf das Druckprodukt auf.To avoid contamination, the nozzles bring the glue according to the invention contactless on the printed product.

Um ein Austrocknen der Düsen zu verhindern bzw. zu vermindern, wenn die Vorrichtung nicht benutzt wird bzw. wenn die Düsen nicht benutzt werden, kann an den Düsen ein Schieber vorgesehen sein, der diese entsprechend abdeckt. Es ist insbesondere möglich, einen Schieber für alle Düsen bzw. für mehrere Düsen der Vorrichtung zu verwenden. Dieser Schieber kann durch eine pneumatische Betätigungseinrichtung betätigbar sein.To prevent or reduce the drying out of the nozzles, if the device is not used or when the nozzles are not used can be provided on the nozzles, a slider, this covers accordingly. In particular, it is possible to have one slider for all To use nozzles or for multiple nozzles of the device. This Slider can be actuated by a pneumatic actuator be.

Ein besonders gleichförmiger Auftrag des Leims erfolgt, wenn die Auftragseinrichtungen im wesentlichen synchron zu einer Bewegung des Druckproduktes bewegt werden. Dieses kann insbesondere dadurch gewährleistet werden, daß eine die Auftragseinrichtungen aufweisende Walze mit entsprechender Geschwindigkeit rotiert wird.A particularly uniform application of the glue takes place when the Applicators substantially synchronous to a movement of the Printed product to be moved. This can especially by be ensured that a the applicators having Roller is rotated at the appropriate speed.

Die Vorrichtung sowie die Verfahrensführung gestalten sich besonders einfach, wenn die Walze formathaltig bezüglich des Druckproduktes ausgebildet ist, d.h. wenn der Umfang der Walze einem ganzzahligen Vielfachen der Durchlauflänge des Druckproduktes oder aber die Durchlauflänge des Druckproduktes einem ganzzahligen Vielfachen des Walzenumfanges entspricht. Insbesondere kann der Umfang der Walze einem Format des Druckproduktes identisch entsprechen.The device and the process control are particularly designed easy if the roller is formate with respect to the printed product is formed, i. if the circumference of the roller is an integer Multiples of the passage length of the printed product or the Passage length of the printed product an integer multiple of the Roller circumference corresponds. In particular, the circumference of the roller correspond identically to a format of the printed product.
