Description

Die Erfindung betrifft ein Verfahren zum Auftragen von Leim auf Bestandteile von Werkstücken zur Herstellung von Säcken oder Beuteln gemäß dem Obergriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des genannten Verfahrens.The invention relates to a method for applying glue to components of workpieces for the production of sacks or bags according to the preamble of claim 1 and to an apparatus for carrying out said method.

Die Patentanmeldung DE 102 55 484 beschreibt ein Leimwerk für eine Bodenlegevorrichtung für Kreuzbodensäcke, welches verschiedene Walzen umfasst. Dazu gehören: eine Format- oder Klischeewalze zum Auftragen von Leim auf Bestandteile der Werkstücke, eine Leimauftragswalze zur Entnahme von Leim aus oder von einer Leimzuführeinrichtung und zum Auftragen des Leims auf die Format- und Klischeewalze und eine der Leimauftragswalze zugeordneten Dosierwalze. Die Umfangsgeschwindigkeiten dieser drei genannten Walzen sind unabhängig voneinander einstellbar. Dazu ist jeder dieser Walzen ein eigener Antriebsmotor zugeordnet.The patent application DE 102 55 484 describes a gluing unit for a bottom-laying device for cross-bottom sacks, which comprises various rollers. These include: a size or plate roller for applying glue to components of the workpieces, a glue application roller for removing glue from or from a glue supply device and for applying the glue to the size and plate roller and a metering roller associated with the glue application roller. The peripheral speeds of these three mentioned rollers are independently adjustable. For this purpose, each of these rollers is assigned its own drive motor.

Derartige Leimwerke werden allerdings nicht nur in Vorrichtungen zur Herstellung von Kreuzbodensäcken verwendet. Ein Beispiel für eine weitere Maschine, in der ein solches Leimwerk eingesetzt werden kann, ist eine Schlauchmaschine, in der Schläuche hergestellt werden, die letztendlich der Herstellung von Säcken oder Beuteln dienen. Solche Schlauchmaschinen können dabei unabhängig von weiteren Maschinen zum Herstellen von Säcken oder Beuteln betrieben werden oder integrale Bestandteile der letztgenannten Maschinen sein. Eine solche Schlauchmaschine ist beispielsweise aus der Patentschrift EP 0 664 208 B1 bekannt. Die vorliegende Erfindung ist allerdings nicht auf die zuvor beschriebenen Maschinen beschränkt.However, such gluing plants are not only used in devices for producing cross-bottom sacks. An example of another machine in which such a gluing unit can be used is a tube machine in which hoses are produced, which ultimately serve for the production of sacks or bags. Such tube machines can be operated independently of other machines for producing sacks or bags or be integral components of the latter machines. Such a hose machine is for example from the Patent EP 0 664 208 B1 known. However, the present invention is not limited to the machines described above.

Um die von der Leimauftragswalze auf die Format- oder Klischeewalze übertragene Leimmenge beeinflussen zu können, ist der Leimauftragswalze die Dosierwalze zugeordnet, wobei die Leimauftragswalze und die Dosierwalze gegensinnig oder gleichsinnig rotieren können. Die Umfangsgeschwindigkeit, mit der die Dosierwalze im Vergleich zur Leimauftragswalze rotiert, beeinflusst dabei die Menge des Leims, den der Leimauftragswalze nach dem Passieren der Dosierwalze anhaftet und den die Leimauftragswalze an die Klischeewalze abgibt.In order to be able to influence the amount of glue transferred from the glue application roller to the size or plate roller, the glue application roller is assigned to the metering roller, wherein the glue application roller and the metering roller can rotate in opposite directions or in the same direction. The circumferential speed with which the metering roller rotates in comparison to the glue application roller, thereby influences the amount of glue that adheres the glue application roller after passing through the metering roller and which emits the glue application roller to the cliché roller.

In der Praxis wird jedoch ein solches Leimwerk betrieben, indem das Verhältnis der Umfangsgeschwindigkeiten der beteiligten Walzen stets fest eingestellt ist. Dabei entspricht die Umfangsgeschwindigkeit der Format- oder Klischeewalze in der Regel der Transportgeschwindigkeit der zu beleimenden Werkstücke, um den Leim nicht über deren Ränder hinweg aufzutragen, was unter anderem eine Verschmutzung der Herstellvorrichtung bedeuten würde. Die Umfangsgeschwindigkeit der Leimauftragwalze weist hingegen in der Regel eine andere Umfangsgeschwindigkeit als die Formatwalze auf. Zur Einstellung der Menge des letztendlich auf die Werkstücke aufgetragenen Leimes wird nun der Abstand zwischen der Dosier- und der Leimauftragswalze eingestellt. Eine Vergrößerung des durch diese beiden Walzen hergestellten Walzenspalts bedeutet in der Regel, dass eine größere Leimmenge auf ein Werkstück aufgetragen wird. Die Einstellung des Abstandes basiert meist jedoch auf Erfahrungswerten des Bedienpersonals.In practice, however, such a gluing plant is operated by the ratio of the peripheral speeds of the rollers involved is always fixed. The peripheral speed of the format or plate roller usually corresponds to the transport speed of the workpieces to be glued so as not to apply the glue beyond their edges, which would mean inter alia soiling of the production device. By contrast, the peripheral speed of the glue application roller generally has a different peripheral speed than the format roller. To adjust the amount of glue finally applied to the workpieces, the distance between the metering and glue application rollers is now set. An increase in the nip produced by these two rolls usually means that a greater amount of glue is applied to a work piece. The adjustment of the distance is usually based on experience of the operating personnel.

Es wurde jedoch festgestellt, dass bei verschiedenen Produktionsgeschwindigkeiten die Menge des auf die Werkstücke aufgetragenen Leims zu hoch, zu niedrig oder starken Schwankungen unterworfen ist. Dies wirkt sich direkt auf die Qualität der produzierten Säcke oder Beutel aus, bei denen dann die Klebungen zum Teil nicht haltbar oder die Außenflächen mit Klebstoff verschmiert sind. So wurde in der Praxis beobachtet, dass beispielsweise bei einer Verarbeitungs-Geschwindigkeit von 30 zu beleimenden Werkstücken pro Zeiteinheit jedes Werkstück mit weniger Leim beaufschlagt wird, als wenn 250 Werkstücke pro Zeiteinheit mit Leim versehen werden.It has been found, however, that at various production speeds, the amount of glue applied to the workpieces is subject to too high, too low or large variations. This has a direct effect on the quality of the bags or bags produced, in which the bonds are sometimes not durable or the outer surfaces are smeared with adhesive. Thus, it has been observed in practice that, for example, at a processing speed of 30 less glue is applied to each workpiece to be glued per unit time than if glue is applied to 250 workpieces per unit of time.

Die Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren und eine Vorrichtung vorzuschlagen, bei denen stets die gleiche, gewünschte Leimmenge auf die zu beleimenden Werkstücke aufgetragen wird.The object of the present invention is therefore to propose a method and a device in which the same, desired amount of glue is always applied to the workpieces to be glued.

Die Aufgabe wird gelöst durch ein Verfahren, welches die Merkmale des Anspruchs 1 umfasst, und durch eine Vorrichtung, die die Merkmale des Anspruchs 3 umfasst.The object is achieved by a method comprising the features of claim 1, and by an apparatus comprising the features of claim 3.

Hierbei wird das Verhältnis der Umfangsgeschwindigkeiten der Leimauftragswalze und der Dosierwalze und/oder das Verhältnis der Umfangsgeschwindigkeiten der Leimauftragswalze und der Format- oder Klischeewalze in Abhängigkeit von Eigenschaften des auf die Werkstücke aufgetragenen Leims eingestellt. Der Erfindung liegt der Gedanke zugrunde, dass sich die Eigenschaften des Leims auf dessen Übertragungsverhalten und damit auf die Menge des auf die Werkstücke aufgetragenen Leims auswirken. Wenn also die Eigenschaften des Leims von Beginn des Produktion der Säcke oder Beutel an zur Einstellung des Verhältnisses der Umfangsgeschwindigkeiten der beteiligten Walzen Berücksichtigung finden, können die Beutel stets mit einer nahezu optimalen Leimmenge beaufschlagt werden. So lassen sich für jeden Leim Verhältnisse der Umfangsgeschwindigkeiten der Walzen finden, bei denen die Menge des Leims auch bei verschiedenen absoluten Umfangsgeschwindigkeiten der Klischeewalze, also letztendlich bei verschiedenen Produktionsgeschwindigkeiten, nahezu konstant ist. Dieser Sachverhalt konnte bei Versuchen ermittelt werden.In this case, the ratio of the circumferential speeds of the glue application roller and the metering roller and / or the ratio of the circumferential speeds of the glue application roller and the size or plate roller are set depending on properties of the glue applied to the workpieces. The invention is based on the idea that the properties of the glue affect its transfer behavior and thus the amount of glue applied to the workpieces. Thus, if the properties of the glue are taken into account from the beginning of the production of the sacks or bags to adjust the ratio of the peripheral speeds of the rollers involved, the bags can always be subjected to an almost optimum amount of glue. Thus, ratios of the peripheral speeds of the rollers can be found for each size, in which the amount of glue is almost constant even at different absolute peripheral speeds of the plate roller, ie ultimately at different production speeds. This situation could be determined during experiments.

In einer Ausführungsform der Erfindung werden den verschiedenen Leimen, die in dem Leimwerk Verwendung finden können, Verhältnisse der Umfangsgeschwindigkeiten der beteiligten Walzen zugeordnet. Diese dann möglichst optimalen Werte könnten auf geeignete Weise, beispielsweise durch entsprechende Versuche, ermittelt. Diese Versuche können etwa durch den Hersteller von Leimwerken durchgeführt werden und die sich ergebenden Werte den Nutzern der Leimwerke zur Verfügung gestellt werden. Die in einem Leimwerk verwendbaren Leime unterscheiden sich in ihren Eigenschaften, die sich auf die Menge des Leims, die auf die Werkstücke übertragen wird, auswirken. Die einzelnen Leime sind charakterisiert durch ihre Eigenschaften wie beispielsweise durch die Viskosität des Leims, durch die Hafteigenschaften des Leims auf den Walzen, durch den Feuchtigkeits- und/oder Feststoffgehalt, also allgemein durch das Ansatzverhältnis, oder durch die verwendeten Rohstoffe. Diese vorgenannten. Eigenschaften können dabei eine "Leimsorte" definieren, wobei die vorstehende Aufstellung keinen Anspruch auf Vollständigkeit erhebt. Aber auch andere Eigenschaften wie das Alter und die Herstellungscharge des Leims sowie dessen Hersteller können im Zusammenhang mit der vorliegenden Erfindung eine Rolle spielen. So kann sich der in zwei verschiedenen Gebinden befindliche Leim gleicher Leimsorte durchaus drastisch in seinen Eigenschaften unterscheiden. Es wird zugrunde gelegt, dass stets die gleichen Walzen eingesetzt werden. Sollten auch andere Walzen zum Einsatz kommen, sind natürlich auch für die verschiedenen Leimeigenschaften die Werte für die Verhältnisse der Umfangsgeschwindigkeiten in Abhängigkeit von den Walzen bzw. deren Eigenschaften zu ermitteln.In one embodiment of the invention, the various glues which can be used in the gluing unit are assigned ratios of the circumferential speeds of the rollers involved. These values, which are then as optimal as possible, could be suitably determined, for example by corresponding tests, determined. These tests can be carried out, for example, by the manufacturer of gluing plants and the resulting values made available to the users of the gluing plants. The glues that can be used in a gluing unit differ in their properties, which affect the amount of glue that is transferred to the workpieces. The individual glues are characterized by their properties such as the viscosity of the glue, by the adhesive properties of the glue on the rollers, by the moisture and / or solids content, ie generally by the approach ratio, or by the raw materials used. These aforementioned. Properties can define a "glue type", whereby the above list does not claim to be complete. However, other properties such as the age and production lot of the size of the glue and its manufacturer may also play a role in the context of the present invention. Thus, the glue of the same type of glue, which is contained in two different containers, can differ drastically in its properties. It is assumed that always the same rolls are used. If other rolls are also used, the values for the ratios of the peripheral speeds as a function of the rolls or their properties must of course also be determined for the different gluing properties.

In einer Ausführungsform der Erfindung sind diese Werte für verschiedene Leime bzw. deren Eigenschaften in einer Speichervorrichtung abgelegt. Angaben über die in dem Leimwerk bei dem nächsten Auftrag verwendeten Leim wird einer Rechen und Steuervorrichtung zugänglich gemacht. Dieses kann beispielsweise dadurch erfolgen, dass das Bedienpersonal aus einer von der Rechen- und Steuervorrichtung zur Verfügung gestellten Liste von Bezeichnungen für die verschiedenen Leime mit einem Eingabegerät eine auswählt. Ein möglicher Leim kann dabei über seine Eigenschaften definiert sein, die beispielsweise durch eine Verkaufsbezeichnung und einer Chargennummer beschrieben werden. Eine andere Möglichkeit ist, dass das Bedienpersonal eine Angabe über die Eigenschaften des zu verwendenden Leims über ein Eingabegerät der Rechen- und Steuervorrichtung mitteilt. Auf Basis dieser An- oder Eingabe kann nun die Rechen- und Steuervorrichtung die zugehörigen Werte aus der Speichervorrichtung abrufen und die entsprechenden Verhältnisse der Umfangsgeschwindigkeiten einstellen.In one embodiment of the invention, these values for different glues or their properties are stored in a storage device. Information about the glue used in the gluing unit in the next application is made available to a rake and control device. This can be done, for example, by the operating personnel selecting one of a number of designations for the different glues with an input device provided by the arithmetic and control device. A possible glue can be defined by its properties, which are described for example by a sales description and a batch number. Another possibility is that the operator can provide an indication of the properties of the glue to be used via an input device of the calculation unit. and control device notifies. Based on this input or input, the computing and control device can now retrieve the associated values from the memory device and set the corresponding ratios of the peripheral speeds.

An dieser Stelle ist anzumerken, dass bisher immer die Rede von den Verhältnissen der Umfangsgeschwindigkeiten der am Leimtransport beteiligten Walzen war. Diese Verhältnisse bleiben in der Regel konstant, wobei sich die absoluten Umfangsgeschwindigkeiten natürlich mit der Maschinengeschwindigkeit ändern. Die Rechen- und Steuereinrichtung steuert allerdings die einzelnen Antriebe, so dass die Walzen die erforderlichen absoluten Umfangsgeschwindigkeiten aufweisen. Dazu berechnet die Steuervorrichtung aus der Maschinengeschwindigkeit und den Werten zu den Verhältnissen der Umfangsgeschwindigkeiten die absoluten Geschwindigkeiten und steuert dementsprechend die Antriebe und/oder Getriebe an.It should be noted at this point that up to now there has always been talk of the ratios of the circumferential speeds of the rolls involved in glue transport. These ratios usually remain constant, with the absolute peripheral speeds naturally changing with machine speed. However, the computing and control device controls the individual drives, so that the rollers have the required absolute peripheral speeds. For this purpose, the control device calculates the absolute speeds from the machine speed and the values relating to the ratios of the peripheral speeds and controls the drives and / or transmissions accordingly.

Es ist auch möglich die Verhältnisse der Umfangsgeschwindigkeiten auch während des Betriebes zu ändern, um auf Veränderungen der Eigenschaften des Leimes während des Betriebes reagieren zu können. Dies ist zum Beispiel dann interessant, wenn sich aufgrund von Temperatureinflüssen die Viskosität des Leims verändert. Solche Einflüsse können durch die Rechen- und Steuereinheit dadurch berücksichtigt werden, dass eine gewisse Verdunstung der Feuchtigkeit des Leims, beispielsweise des Wassers, angenommen wird. Die entsprechenden Verdunstungsraten können in der Speichereinheit hinterlegt sein.It is also possible to change the ratios of the circumferential speeds during operation in order to be able to react to changes in the properties of the glue during operation. This is interesting, for example, when the viscosity of the glue changes due to temperature influences. Such influences can be taken into account by the computing and control unit, that a certain evaporation of the moisture of the glue, for example, the water is assumed. The corresponding evaporation rates can be stored in the memory unit.

Weitere Ausführungsbeispiele der Erfindung gehen aus der gegenständlichen Beschreibung und den Ansprüchen hervor.Further embodiments of the invention will become apparent from the description and the claims.

Fig. 1 zeigt schematisch eine Leimauftragsstation 1, wie es typischerweise Maschinen zur Herstellung von Säcken mit Kreuzböden verwendet wird. Diese Maschinen werden in Fachkreisen auch als Bodenlegevorrichtungen bezeichnet. Solche Säcke können einen oder zwei solcher Böden aufweisen, die mit Ventilen versehen und/oder mit Bodendeckblättern verstärkt sein können. Die späteren Böden werden in der Bodenlegevorrichtung an Schlauchstücke angeformt. Sowohl die Schlauchstücke bzw. die Säcke als auch Ventile und Bodendeckblätter werden im Rahmen der Erfindung als Werkstücke bezeichnet. Solche Werkstücke können in einer gezeigten Leimauftragsstation mit einem Leimauftrag versehen werden, um dann später mit sich selbst (im Falle der einzelnen den späteren Boden formenden Klappen oder Laschen am Schlauchstück) oder mit anderen Werkstücken verbunden zu werden. Fig. 1 schematically shows a glue application station 1, as it is typically used machines for the production of bags with cross bottoms. These machines are referred to in professional circles as Bodenlegevorrichtungen. Such bags may have one or two such trays, which may be provided with valves and / or reinforced with bottom cover sheets. The later soils are molded in the floor laying device to pieces of hose. Both the pieces of tubing or the bags as well as valves and bottom cover sheets are referred to as workpieces within the scope of the invention. Such workpieces may be provided with glue in a glue application station shown, and then later joined to themselves (in the case of the individual bottom forming flaps or tabs on the length of tubing) or to other workpieces.

Aber auch in Schläuche produzierenden Maschinen, den so genannten Schlauchmaschinen, können Leimauftragsstationen 1 vorgesehen sein. In einer solchen Schlauchmaschine können eine flache Materialbahn oder mehrere übereinander liegende Materialbahnen, deren Längskanten allerdings vorzugsweise nicht übereinander liegen, sondern seitlich versetzt sind, mit ihren Seitenkanten um eine Längsrichtung umgeschlagen werden, so dass sich die beiden Randbereiche einer jeden Materialbahnlage überlappen. Diese Überlappungsbereiche können mithilfe einer Leimauftragsstation 1 mit Leim versehen werden, so dass sich eine dauerhafte Verbindung entlang des Überlappungsbereichtes ergibt. Dieser so entstandene Schlauch kann später noch in so genannten Abreißwerken zu Schlauchstücken vereinzelt werden, welche dann direkt im Anschluss oder erst später nach einer Zwischenlagerung zu Säcken oder Beuteln verarbeitet werden. Die Materialbahnen zur Bildung eines Schlauches werden durch die hier verwendete Bezeichnung "Werkstücke" mit umfasst.But also in hoses-producing machines, the so-called hose machines, glue application stations 1 can be provided. In such a tube machine, a flat material web or a plurality of superimposed material webs, the longitudinal edges, however, preferably not superimposed, but are laterally offset, are folded with their side edges to a longitudinal direction, so that overlap the two edge regions of each web position. These overlapping areas can be provided with glue by means of a glue application station 1, resulting in a permanent connection along the overlapping area. This resulting tube can later be separated into so-called tear-offs to pieces of tubing, which are then processed directly after or later to an intermediate storage to sacks or bags. The material webs for forming a hose are encompassed by the term "workpieces" as used herein.

Werkstücke 3 werden mittels einer schematisch dargestellten Transporteinrichtung 2 durch die Leimauftragsstation 1 hindurch geführt. In dieser Leimauftragsstation 1 bilden die Gegendruckwalze 4 und die Klischeewalze 5 einen Walzenspalt 6, bei dem die beiden betreffenden Walzen in der Regel so aneinander angestellt sind, dass das Klischee 7 mit Überdruck an der Gegendruckwalze 4 bzw. dem Werkstück 3 anliegt. Beim Passieren des Walzenspalts 6 wird das Werkstück 3 auf seiner der Klischeewalze 5 zugewandten Seite mit Leim belegt. Zu diesem Zweck trägt die Klischeewalze 5 so genannte Klischees 7, die kongruent zu der mit Leim zu beaufschlagenden Fläche des Werkstücks 3 sind. Lediglich das Klischee trägt den Leim, so dass, eine passende Phasen- und Höhenlage des Werkstücks 3 und des Klischees 7 vorausgesetzt, nur die vorgesehene Fläche mit Leim versehen wird.Workpieces 3 are guided through the glue application station 1 by means of a transport device 2 shown schematically. In this glue application station 1, the counterpressure roller 4 and the plate roller 5 form a roller nip 6, in which the two rollers in question are usually placed against one another such that the plate 7 bears against the counterpressure roller 4 or the workpiece 3 with overpressure. When passing through the nip 6, the workpiece 3 is coated on its side facing the cliché roller 5 with glue. For this purpose, the cliché roller 5 carries so-called clichés 7, which are congruent with the surface of the workpiece 3 to be treated with glue. Only the cliché carries the glue, so that provided a suitable phase and height position of the workpiece 3 and the plate 7, only the intended surface is provided with glue.

Die Klischeewalze 5 wird von der Leimauftragswalze 8 mit Leim 9 versorgt, welcher in dem Leimbehälter 10 bevorratet wird. Der Leimauftragswalze 8 ist eine Dosierwalze 11 zugeordnet, mit weicher sich die Entnahme des Leims 9 aus dem Leimbehälter 10 einstellen lässt. Die Dosierwalze 11 ist der Leimauftragswalze 8 angenähert, berührt diese aber im Betrieb nicht, so dass beide Walzen einen Walzenspalt 20 bilden, durch den der Leim 9 aus dem Leimbehälter entnommen werden kann. Die Drehrichtungen der einzelnen Walzen 5, 8 und 11 sind durch die Pfeile D5, D8 und D11 symbolisiert. Die Drehrichtung D4 der Walze 4 ist ebenfalls dargestellt. In dem gezeigten Ausführungsbeispiel drehen die Walzen 11 und 8 gleichsinnig. Im Bereich des durch diese Walzen gebildeten Walzenspalts laufen die Umfangsflächen also genau entgegengesetzt. Die Menge des mit der Leimauftragswalze 8 aus dem Leimbehälter 10 entnommenen Leims 9 kann durch eine Veränderung des Walzenspaltes 20 verändert werden. Dazu kann die Dosierwalze 11 im Wesentlichen entlang der durch einen Doppelpfeil symbolisierten Bewegungsrichtung A verschoben werden.The cliché roller 5 is supplied by the glue application roller 8 with glue 9, which is stored in the glue container 10. The glue application roller 8 is associated with a metering roller 11, with which the removal of the glue 9 from the glue container 10 can be adjusted. The metering roller 11 is approximated to the glue application roller 8, but does not touch it during operation, so that both rollers form a nip 20 through which the glue 9 can be removed from the glue container. The directions of rotation of the individual rollers 5, 8 and 11 are symbolized by the arrows D5, D8 and D11. The direction of rotation D4 of the roller 4 is also shown. In the embodiment shown, the rollers 11 and 8 rotate in the same direction. In the area of the nip formed by these rollers, the peripheral surfaces thus run exactly opposite. The amount of adhesive removed with the glue application roller 8 from the glue container 10 can be changed by changing the nip 20. For this purpose, the metering roller 11 can be displaced substantially along the direction of movement A symbolized by a double arrow.

Je nach Beschaffenheit des verwendeten Werkstücks kann vorgesehen sein, unterschiedliche Leime, die unter anderem auf diese Beschaffenheiten abgestimmt sind, in dem Leimbehälter 10 zur Verfügung zu stellen. Daran sind nun die Umfangsgeschwindigkeiten der am Leimtransport beteiligten Walzen anzupassen, um auch bei Veränderungen der absoluten Drehgeschwindigkeiten der am Leimtransport beteiligten Walzen die Menge des auf die Werkstücke 3 aufgetragenen Leims konstant zu halten. Dieses erfolgt vorteilhafterweise durch eine passende Einstellung der Umfangsgeschwindigkeit der Dosierwalze 11 in einem festen Verhältnis zu der Umfangsgeschwindigkeit der Leimauftragswalze 8 in Abhängigkeit vom verwendeten Leim. Diese Einstellung erfolgt bevorzugt vor Produktionsbeginn, kann aber auch bei laufender Produktion durchgeführt werden.Depending on the nature of the workpiece used can be provided in the glue container 10 different glues, which are adapted inter alia to these textures available. This is what the peripheral speeds of the rollers involved in glue transport are now adapt to keep the amount of glue applied to the workpieces 3 constant even when changing the absolute rotational speeds of the rollers involved in glue transport. This is advantageously done by a suitable adjustment of the peripheral speed of the metering roller 11 in a fixed ratio to the peripheral speed of the glue application roller 8, depending on the glue used. This setting preferably takes place before the start of production, but can also be carried out during ongoing production.

Die Figur 2 zeigt die Ansicht II - II in der Figur 1. Die Ansicht I - I in der Figur 2 weist nochmals auf die in der Figur 1 dargestellte Sicht hin. In der Figur 2 sind zusätzlich zu den in Figur 1 dargestellten Elementen die Tragplatte 13, an welcher die Leimauftragswalze 8 und die Dosierwalse 11 fliegend und drehbar gelagert sind, und die Antriebsmotoren 14 und 15 für die Leimauftragswalze 8 und die Dosierwalze 11 dargestellt. Darüber hinaus ist eine Leimzuführleitung 12 gezeigt, über welche dem Leimbehälter 10 weiterer Leim aus einem Leimtank zuführbar ist.The FIG. 2 shows the view II - II in the FIG. 1 , The view I - I in the FIG. 2 points again to the in the FIG. 1 represented view. In the FIG. 2 are in addition to the in FIG. 1 elements shown, the support plate 13 to which the glue applicator roll 8 and the Dosierwalse 11 are mounted flying and rotatable, and the drive motors 14 and 15 for the glue applicator roller 8 and the metering roller 11 shown. In addition, a glue supply line 12 is shown, via which the glue container 10 further glue from a glue tank can be fed.

Die beiden Antriebsmotoren 14 und 15 werden von der Rechen- und Steuereinheit 16 in ihrer Drehzahl eingestellt, so dass für die Walzen die gewünschte Umfangsgeschwindigkeit einstellbar ist. Um nun die gewünschte bzw. die für den optimalen Leimauftrag passenden Umfangsgeschwindigkeiten einstellen zu können, die wie beschrieben von der Leimsorte abhängen kann, können auf der beispielsweise als Monitor ausgestalteten Anzeige- oder Ausgabeeinrichtung 17 mehrere Verkaufsbezeichnungen der Leime sowie weitere zugehörige Informationen angezeigt werden. Diese auf den Leim bezogenen Informationen und die zugehörigen Verhältnisse der Umfangsgeschwindigkeiten sind in einer nicht gezeigten Speichereinrichtung, auf die die Rechen- und Steuereinrichtung 16 Zugriff hat und die in der Rechen- und Steuereinrichtung integriert sein kann, gespeichert. Über das Eingabegerät 18 kann der Maschinenbediener nun den für den neuen Auftrag in den Leimbehälter 10 einzubringenden Leim auswählen und bestimmen. Aus der Bestimmung des Leims ruft der Rechen- und Steuervorrichtung nun aus dem Speicher den zugeordneten Wert für das Verhältnis der Umfangsgeschwindigkeiten der Leimauftragswalze 8 und der Dosierwalze 11 ab.The two drive motors 14 and 15 are set by the computing and control unit 16 in their speed, so that the desired peripheral speed is adjustable for the rollers. In order to be able to set the desired peripheral velocities, which may depend on the size of the glue, as described, a plurality of sales marks of the glues as well as further associated information can be displayed on the display or output device 17, for example as a monitor. These information relating to the glue and the associated ratios of the peripheral speeds are stored in a storage device, not shown, to which the computing and control device 16 has access and which can be integrated in the computing and control device. Via the input device 18, the machine operator can now select and determine the glue to be introduced into the glue container 10 for the new application. From the determination of the glue the computing and control device calls now from the memory the assigned value for the ratio of Peripheral speeds of the glue application roller 8 and the metering roller 11 from.

Die Figur 3 zeigt ein weiteres Ausführungsbeispiel einer erfindungsgemäßen Vorrichtung, bei der der Leimbehälter 10 durch eine Leimdüse 19 ersetzt worden ist. Diese Leimdüse 19 ist, wie im Übrigen auch der Leimbehälter 10, an der Tragplatte 13 befestigbar. Die Wahl der Leimzuführeinrichtung, also die Auswahl aus Leimbehälter 10 und Leimdüse 19, hat ebenfalls Einfluss auf die einzustellenden Umfangsgeschwindigkeiten der am Leimtransport beteiligten Walzen. Daher kann die Rechen- und Steuereinrichtung 16, die in dieser Figur 3 nicht nochmals dargestellt ist, bei dem Einsatz einer Leimdüse 19 im Vergleich zur Verwendung eines Leimbehälters ein anderes Verhältnis der Umfangsgeschwindigkeiten der Leimauftragswalze 8 und der Dosierwalze 11 bei ein und demselben Leim einstellen. Die den einzelnen Leimen zugeordneten Informationen bzw. Verhältnisse der Umfangsgeschwindigkeiten können daher zusätzlich in Bezug auf die Leimzuführeinrichtung untergliedert sein.

This glue nozzle 19, as well as the glue container 10, on the support plate 13 can be fastened. The choice of Leimzuführeinrichtung, so the selection of glue container 10 and glue nozzle 19, also has an influence on the set peripheral speeds of the rollers involved in glue transport. Therefore, the computing and control device 16, which in this FIG. 3 is not shown again, set in the use of a glue nozzle 19 compared to the use of a glue container, a different ratio of the peripheral speeds of the glue applicator roll 8 and the metering roller 11 at the same glue. The information or ratios of the peripheral velocities assigned to the individual glues can therefore also be subdivided with respect to the glue supply device.
