BESCHREIBUNG DESCRIPTION
VORRICHTUNG UND VERFAHREN ZUM AUFBRINGEN EINES VON EINER SPENDERROLLE ABGEWICKELTEN BANDES, INSBESONDERE KLEBEBANDESDEVICE AND METHOD FOR APPLYING A TAPE UNWINDED FROM A DISPENSER REEL, IN PARTICULAR ADHESIVE TAPE
Die Erfindung betrifft eine Vorrichtung zum Aufbringen eines von einer Spenderrolle abgewickelten Bandes, insbesondere eines Klebebandes auf eine zu beklebende Oberfläche.The invention relates to a device for applying a tape unwound from a dispenser roll, in particular an adhesive tape, to a surface to be glued.
Zum Aufbringen von Bändern, insbesondere Klebebändern sind sog. Klebeköpfe bekannt, die beim Aufbringen des Bandes auf die Oberfläche eine Relativbewegung zur Oberfläche vollziehen. Wenn von einer Relativbewegung gesprochen wird, so kann entweder die Oberfläche des Kleblings unter dem Klebekopf bewegt werden oder der Klebekopf wird in Kleberichtung über der Oberfläche des Klebekopfes geführt, um den Aufklebevorgang zu vollziehen. Die Bänder, die im Zusammenhang mit der Erfindung angesprochen sind, können entweder nicht selbstklebende Bänder sein, wozu dann der Klebling oder das Band gesondert mit einer Klebeschicht versehen werden muß, ebenso werden aber auch Klebebänder von der Erfindung umfaßt, die eine klebende Schicht auf einem Trägermaterial aufweisen oder lediglich aus einer Klebeschicht bestehen.So-called adhesive heads are known for applying tapes, in particular adhesive tapes, which perform a movement relative to the surface when the tape is applied to the surface. If one speaks of a relative movement, then either the surface of the adhesive can be moved under the adhesive head or the adhesive head is guided in the adhesive direction over the surface of the adhesive head in order to carry out the gluing process. The tapes that are addressed in connection with the invention can either be non-self-adhesive tapes, for which purpose the adhesive or the tape must be provided separately with an adhesive layer, but also adhesive tapes are also included by the invention, which have an adhesive layer on one Have carrier material or consist only of an adhesive layer.
Die Klebeköpfe der bekannten Norrichtungen weisen eine Mehrzahl von Führungsrollen auf, die das Band geführt einer Andruckrolle des Klebekopfes zuführen. Die Andruckrolle ist die unmittelbar über die Klebelinie des Kleblings geführte Rolle, die für einen innigen Kontakt des zu verklebenden Bandes mit der Oberfläche des Kleblings sorgt.The adhesive heads of the known standard devices have a plurality of guide rollers which guide the tape to a pressure roller of the adhesive head. The pressure roller is the roller that runs directly over the adhesive line of the adhesive, which ensures intimate contact of the tape to be bonded with the surface of the adhesive.
In der Regel haben automatische Vorrichtungen zum Aufbringen eines von einer Spenderrolle abgewickelten Bandes auch eine Steuerschaltung, um von der Spenderrolle das Band zugarm abführen zu können.As a rule, automatic devices for applying a tape unwound from a dispenser roll also have a control circuit in order to be able to remove the tape with low tension from the dispenser roll.
Aus DE 197 29 026 ist ein Verfahren und eine Vorrichtung zum Aufkleben eines von einer Vorratsrolle abgezogenen und abgelängten Abschnittes eines Klebebandes bekannt. Das freie Ende des Klebebandes wird an seiner Klebeseite von einem Greifer erfaßt, wozu komplizierte mechanische Bewegungsvorgänge erforderlich sind. Aus EP 0 325 855 B 1 ist eine Klebstoffauftragevorrichtung mit selbsttätigem Tragebandvorschub bekannt.DE 197 29 026 discloses a method and a device for gluing on a portion of an adhesive tape which has been pulled off and cut to length from a supply roll. The free end of the adhesive tape is gripped on its adhesive side by a gripper, which requires complicated mechanical movement processes. EP 0 325 855 B1 discloses an adhesive application device with an automatic carrying tape feed.
Aus DE 199 36 130 ist ein Bandabroller, insbesondere ein Klebebandabroller bekannt, bei welchem zur leichteren Handhabung und leichteren Ablängen des Bandes ohne Verletzungsgefahr an einer scharfen Schneidklinge, die Schneidklinge aus einer Ruhestellung in Schnittstellung entgegen der Kraft einer vorgespannten Feder schwenkbar am Bandabroller angeordnet ist.DE 199 36 130 discloses a tape dispenser, in particular an adhesive tape dispenser, in which, for easier handling and easier cutting to length of the tape without risk of injury on a sharp cutting blade, the cutting blade is pivotably arranged on the tape dispenser from a rest position in the cutting position against the force of a prestressed spring.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit den Merkmalen des Anspruches 1 derart auszubilden, daß das Band im Klebekopf sicher geführt wird und auf Anforderung, insbesondere nach dem Abschneiden unterschiedliche Zugbelastungen auf das Band ausgeübt werden können. Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Vorteilhafte Weiterbildungen der Vorrichtung ergeben sich aus den Unteransprüchen 2 -23. Gemäß Anspruch 24 betrifft die Erfindung auch ein Verfahren zur Aufbringung eines Bandes, insbesondere eines Klebebandes auf eine Oberfläche eines Kleblings mit einem Klebekopf. Vorteilhafte Weiterbildungen des Verfahrens ergeben sich aus den Unteransprüchen 25 - 27.The invention has for its object to provide a device with the features of claim 1 such that the tape is securely guided in the adhesive head and different tensile loads can be exerted on the tape on request, especially after cutting. The object is achieved by the characterizing features of claim 1. Advantageous further developments of the device result from subclaims 2-23. According to claim 24, the invention also relates to a method for applying a tape, in particular an adhesive tape to a surface of an adhesive with an adhesive head. Advantageous further developments of the method result from subclaims 25-27.
Nach der Merkmalskombination des Vorrichtungsanspruches 1 ist im Klebekopf eine Förderrolle angeordnet, der zur Förderung und Traktion eine Gegenrolle zugeordnet ist, wobei das Band zwischen Förderrolle und Gegenrolle verläuft. Die Förderrolle, auch als Masterrolle bezeichnet, ist verantwortlich für die Laufgeschwindigkeit des Bandes im Klebekopf. Durch das Zusammenwirken zwischen Förderrolle und Gegenrolle wird das Band in diesem Bereich sehr innig geführt und kann auch geklemmt werden, um beispielsweise einen Trennvorgang zu unterstützen. Förderrolle und Andruckrolle sind deshalb so angetrieben, daß die Andruckrolle zumindest zeitweise eine höhere Umfangsgeschwindigkeit hat als die Förderrolle. Wenn in diesem Zusammenhang von zumindest zeitweise gesprochen wird, so bedeutet dies zum einen, daß die Andruckrolle immer mit einer etwas höheren Umfangsgeschwindigkeit laufen kann als die Förderrolle. Dies hat den Vorteil, daß eine Schlaufenbildung im Bereich zwischen Förderrolle und Andruckrolle vermieden wird. In diesem Falle läuft das Band auf der bandführenden radialen Außenfläche der Andruckrolle immer mit etwas Schlupf. Es liegt aber auch im Rahmen der Erfindung, daß im normalen Förderzustand die Umfangsgeschwindigkeiten in der Förderrolle und Andruckrolle gleich sind, die Förderrolle aber zeitweise gestoppt werden kann, wodurch das Band angehalten wird. Wird vor diesem Stop das Band definiert angeschnitten, so kann ein Abreißen des Bandes verursacht werden, und zwar in einem Bereich, der sich bereits auf der bandführenden Fläche der Andruckrolle befindet. Dies hat den Vorteil, daß der abgeschnittene Abschnitt des Bandes fertig auf die Oberfläche des Kleblings aufgeklebt werden und kann der Beginn des nachfolgenden Abschnittes aber bereits an der Andruckrolle anliegt, ohne daß direkt auf der Oberfläche der Andruckrolle geschnitten werden muß. Der Schneidvorgang kann zwischen Förderrolle und Andruckrolle vorgenommen werden. Dazu ist zwischen der Förderrolle und der Andruckrolle eine weitere, mit einem Schneidemesser zusammenwirkende angetriebene Rolle angeordnet. Diese Rolle hat eine „Ambos"-Funktion. Mit Vorteil ist es möglich, auch deren Umfangsgeschwindigkeit höher zu wählen als die Umfangsgeschwindigkeit der Förderrolle um Schlaufenbildung zwischen Ambosrolle und Förderrolle zu vermeiden. Vor der Förderrolle können angetriebene Umlenkrollen angeordnet werden, durch welche das von der Spenderrolle kommende Band in den Klebekopf eingeführt wird.According to the combination of features of the device claim 1, a conveyor roller is arranged in the adhesive head, which is assigned a counter roller for conveying and traction, the belt running between the conveyor roller and counter roller. The conveyor roller, also known as the master roller, is responsible for the running speed of the belt in the adhesive head. Due to the interaction between the conveyor roller and counter roller, the belt is guided very intimately in this area and can also be clamped in order to support a separation process, for example. Conveyor roller and pinch roller are therefore driven so that the pinch roller at least at times has a higher peripheral speed than the conveyor roller. If one speaks of at least temporarily in this context, this means on the one hand that the pressure roller can always run at a somewhat higher peripheral speed than the conveyor roller. This has the advantage that a loop formation in the area between the conveyor roller and the pressure roller is avoided. In this case, the tape always runs with a little slip on the radial outer surface of the pressure roller that guides the tape. But it is also in the Framework of the invention that in the normal conveying state, the peripheral speeds in the conveyor roller and pinch roller are the same, but the conveyor roller can be stopped temporarily, whereby the belt is stopped. If the tape is cut in a defined manner before this stop, the tape can be torn off, in an area that is already on the tape-guiding surface of the pressure roller. This has the advantage that the cut-off section of the tape is glued ready to the surface of the adhesive and the beginning of the following section can already rest on the pressure roller without having to cut directly on the surface of the pressure roller. The cutting process can be carried out between the conveyor roller and the pressure roller. For this purpose, a further driven roller, which interacts with a cutting knife, is arranged between the conveyor roller and the pressure roller. This roller has an "anvil" function. It is advantageously also possible to select its peripheral speed higher than the peripheral speed of the conveyor roller in order to avoid loops forming between the anvil roller and conveyor roller. Driven deflection rollers can be arranged in front of the conveyor roller, through which the Dispenser roll coming tape is inserted into the adhesive head.
Es liegt im Rahmen der Erfindung, die angetriebenen Rollen des Klebekopfes durch einen gemeinsamen Motor anzutreiben, wozu dann Kupplungs- oder Getriebeelemente vorgesehen werden müssen, um die Förderrolle antriebsmäßig abzukoppeln und/oder zu blockieren, während die anderen Rollen weiterlaufen. Es ist aber auch möglich, dieIt is within the scope of the invention to drive the driven rollers of the adhesive head by a common motor, for which purpose coupling or gear elements must then be provided in order to decouple and / or block the conveyor roller while the other rollers continue to run. But it is also possible that
Förderrolle mit einem gesonderten Motor zu versehen und die anderen angetriebenenTo provide conveyor roller with a separate motor and the other driven
Rollen über einen weiteren Motor anzutreiben. Die Motoren können mit Vorteil als Servo-To drive rollers via another motor. The motors can advantageously be used as servo
Motoren ausgestaltet sein, die über eine Steuerschaltung angesteuert werden können.Motors can be designed, which can be controlled via a control circuit.
Die Andruckrolle ist eine mit radial zur außenliegenden Andruckfläche führendenThe pressure roller is one that leads radially to the outer pressure surface
Unterdruckkanälen versehene Rolle. Derartige Rollen sind im Prinzip bekannt. Gemäß derRoller provided with vacuum channels. Such roles are known in principle. According to the
Erfindung kann der Unterdruck gesteuert werden, um auf unterschiedlicheInvention, the vacuum can be controlled to different
Bandverhältnisse, d. h. Bandoberflächenbeschaffenheiten oder Steifigkeiten reagieren zu können.Band ratios, d. H. Belt surface textures or stiffness can react.
Die Umfangsgeschwindigkeiten der Förderrolle und der Andruckrolle können so unterschiedlich gewählt werden, daß die Andruckrolle immer eine etwas höhere Umfangsgeschwindigkeit als die Förderrolle hat, so daß das Band mit geringem Schlupf auf der Andruckfläche der Andruckrolle gleitet..The peripheral speeds of the conveyor roller and the pressure roller can be chosen so differently that the pressure roller always a little higher Has peripheral speed than the conveyor roller, so that the belt slides with little slip on the pressure surface of the pressure roller ..
Das Schneidemesser der Schneidevorrichtung kann beim Schneidevorgang annähernd in Radialrichtung auf die mit ihm zusammenwirkende Ambos-Rolle zugeführt werden. DasDuring the cutting process, the cutting knife of the cutting device can be fed approximately in the radial direction onto the anvil roll interacting with it. The
Schneidemesser ist dabei um einen geringfügigen Winkelbereich schwenkbar befestigt.The cutting knife is fastened so that it can be pivoted through a slight angular range.
Die Schwenkbewegung des Schneidemessers wird dadurch verursacht, daß dieThe pivoting movement of the cutting knife is caused by the fact that the
Messerspitze in das bewegte Band eindringt und vom bewegten Band mitgenommen wird.Knife tip penetrates into the moving belt and is carried along by the moving belt.
Dabei ist bedeutungsvoll, daß das Band nicht gänzlich vom Schneidemesser durchtrennt wird, sondern der eigentliche Trennvorgang an der durch das Band angeschnittenen Stelle erst im Bereich der Andruckrolle erfolgt und zwar dadurch, daß die Förderrolle gestoppt wird, wohingegen der eigentliche Klebevorgang bei angetriebener Andruckrolle fortgeführt wird. Dadurch entsteht auf die Schnittstelle ein derartiger Zug, daß das Band an dieser Stelle gezielt abreißt.It is important that the tape is not completely cut by the cutting knife, but that the actual cutting process at the point cut by the tape only takes place in the area of the pressure roller, namely by stopping the conveyor roller, whereas the actual gluing process is continued when the pressure roller is driven , This creates such a pull on the interface that the tape breaks off at this point.
Die Ansprüche 15 - 23 befassen sich mit einer elektronischen Steuerungseinrichtung, die in die Vorrichtung integriert oder gesondert ausgebildet und über elektrische Schaltmittel mit der Vorrichtung wirkverbunden sein kann. In die Steuerungseinrichtung kann auch einClaims 15-23 are concerned with an electronic control device which can be integrated into the device or designed separately and can be operatively connected to the device via electrical switching means. A can also be in the control device
Regelungs- oder ein Meßsystem integriert sein, über welches Bandabzugs- und Aufklebegeschwmdigkeiten und/oder Relativbewegungen zwischen dem Klebekopf und einem zu beklebenden Gegenstand erfaßt werden können. Regelungs- /Meßsystem und Steuerungseinrichtung können integriert ausgebildet sein. Außerdem ist es vorteilhaft, wenn in einem Speicher der Steuerungseinrichtung eine Mehrzahl von Klebeprogrammen angespeichert ist, die abhängig von Art der Klebebänder und der zu beklebenden Flächen abrufbar sind. Dadurch ist es möglich, auf einfache Weise die Funktion des Klebekopfes an die mechanischen atesiven Eigenschaften der Klebebänder anzupassen.Control or a measuring system can be integrated, by means of which tape pull-off and stick-on speeds and / or relative movements between the sticking head and an object to be stuck on can be detected. Regulation / measuring system and control device can be integrated. It is also advantageous if a plurality of adhesive programs are stored in a memory of the control device and can be called up depending on the type of adhesive tapes and the surfaces to be adhered to. This makes it possible to easily adapt the function of the adhesive head to the mechanical, aggressive properties of the adhesive tapes.
Die Erfindung ist anhand eines Ausführungsbeispieles in den Zeichnungsfiguren näher erläutert. Diese zeigen:The invention is explained in more detail using an exemplary embodiment in the drawing figures. These show:

Die Vorrichtung zum Aufbringen eines von einer nicht dargestellten Spenderrolle abgewickelten Bandes 1 umfaßt einen Klebekopf 2, der beim Aufbringen des Bandes auf eine zu beklebende Oberfläche 3 eine Relativbewegung zur Oberfläche vollzieht, die mit dem Pfeil 4 angedeutet ist. In dem Klebekopf 2 ist eine Mehrzahl von Führungsrollen 5, 6 und 7 vorgesehen, durch welche das Band 1 von der Spenderrolle kommend in den Klebekopf 2 eingeführt wird.The device for applying a tape 1 unwound from a dispenser roll, not shown, comprises an adhesive head 2 which, when the tape is applied to a surface 3 to be glued, makes a movement relative to the surface, which is indicated by the arrow 4. A plurality of guide rollers 5, 6 and 7 is provided in the adhesive head 2, through which the tape 1 is inserted into the adhesive head 2 coming from the dispenser roller.
Zusätzlich kann eine Steuerschaltung vorgesehen werden, über die ein zugarmes Abrollen des Bandes 1 von der Spenderrolle und eine definiertes Führen des Bandes im Klebekopf 2 verursacht werden kann.In addition, a control circuit can be provided via which a low-tension unrolling of the tape 1 from the dispenser roll and a defined guiding of the tape in the adhesive head 2 can be caused.
Im Klebekopf 2 ist eine Förderrolle 8 angeordnet, der zur Förderung und Traktion des Bandes 1 eine Gegenrolle 9 zugeordnet ist, wobei das Band 1 klemmgeführt zwischenIn the adhesive head 2, a conveyor roller 8 is arranged, which is assigned a counter roller 9 for conveying and traction of the belt 1, the belt 1 being guided between the clamps
Förderrolle 8 und Gegenrolle 9 verläuft. Von der Förderrolle 8 läuft das Band zu einerConveyor roller 8 and counter roller 9 runs. The belt runs from the conveyor roller 8 to one
Andruckrolle 10, durch die das Band 1 gegen die Oberfläche 3 des Kleblings geführt wird.Pressure roller 10, through which the tape 1 is guided against the surface 3 of the adhesive.
Die Förderrolle 8 und die Andruckrolle 10 sind derart angetrieben, daß die AndruckrolleThe conveyor roller 8 and the pressure roller 10 are driven such that the pressure roller
10 zumindest zeitweise einen höhere Umfangsgeschwindigkeit hat als die Förderrolle 8.10 at least at times has a higher peripheral speed than the conveyor roller 8.
Zwischen der Förderrolle 8 und der Andruckrolle 10 ist eine weitere, mit einemBetween the conveyor roller 8 and the pressure roller 10 is another, with a
Schneidemesser 11 einer Schneidvorrichtung 12 zusammenwirkende angetriebene Rolle 13 angeordnet, deren Umfangsgeschwindigkeit ebenfalls höher ist als dieCutting knife 11 of a cutting device 12 cooperating driven roller 13 is arranged, the peripheral speed is also higher than that
Umfangsgeschwindigkeit der Förderrolle 8. Das Schneidemesser 11 ist an einer Pendelachse 14 pendelnd in der Schneidevorrichtung 12 befestigt und kann in Pfeilrichtung 15 gegen die Rolle 13 geführt werden, um das Band 1 an dieser Stelle anzuschneiden. Für den Antrieb der Rollen 7, 8, 10 und 13 ist mindestens ein Motor vorgesehen, der zeichnerisch nicht dargestellt ist. Die Andruckrolle 10 ist mit Unterdruckkanälen 16 versehen, die zur radial außenliegenden Andruckfläche 17 der Andruckrolle 10 führen, so daß das auf der Peripherie der Andruckrolle 10 liegende Band dort sicher gehalten und geführt wird. Aufgrund der höheren Umfangsgeschwindigkeit der Andruckrolle 10 gegenüber der Förderrolle 8 läuft das Band 1 mit geringem Schlupf über die radial außenliegenden Öffnungen 18 der Andruckrolle 10. Die Drehbewegung der Förderrolle 8 kann von der Drehbewegung der Andruckrolle 10 und/oder der mit dem Schneidemesser 11 zusammenwirkenden Rolle 13 abgekoppelt werden, wodurch das Band zwischen der Förderrolle 8 und der Gegenrolle 9 geklemmt, d. h. festgehalten wird und auf die angeschnittene Stelle des Bandes, die dann bereits auf der Andruckrolle 10 aufliegt, ein so hoher Zug ausgeübt wird, daß das Band definiert an dieser Stelle abreißt.Circumferential speed of the conveyor roller 8. The cutting knife 11 is attached to a pendulum axis 14 in the cutter 12 and can be guided in the direction of arrow 15 against the roller 13 in order to cut the belt 1 at this point. At least one motor is provided for driving the rollers 7, 8, 10 and 13, which is not shown in the drawing. The pressure roller 10 is provided with vacuum channels 16 which lead to the radially outer pressure surface 17 of the pressure roller 10, so that the tape lying on the periphery of the pressure roller 10 is securely held and guided there. Due to the higher peripheral speed of the pressure roller 10 compared to the conveyor roller 8, the belt 1 runs with little slippage over the radially outer openings 18 of the pressure roller 10. The rotary movement of the conveyor roller 8 can be decoupled from the rotary movement of the pressure roller 10 and / or the roller 13 interacting with the cutting knife 11, whereby the belt is clamped between the conveyor roller 8 and the counter roller 9, ie is held and on the cut point of the belt, which then already rests on the pressure roller 10, such a high tension is exerted that the tape breaks off at this point in a defined manner.
Beim eigentlichen Schneidevorgang wird das Schneidemesser 11 so gegen die Rolle 13 geführt, daß es vor dem der Schneidevorrichtung nächstliegenden Oberflächenpunkt der Rolle 13 in das Band 1 eindringt. Das Schneidemesser 11 wird dann in Bandlaufrichtung verschwenkt und erreicht dabei die der Schneidevorrichtung 12 nächstliegende Stelle der Rolle 13. Sobald durch die Schneidevorrichtung 12 das Schneidemesser 11 wieder entgegen Pfeilrichtung 15 zurückgezogen wird, sorgt eine Schwenk-Rückführfeder 19 dafür , daß das Schneidemesser 11 um die Pendelachse 14 wieder zurück in die Ausgangsposition schwenkt.During the actual cutting process, the cutting knife 11 is guided against the roller 13 in such a way that it penetrates into the strip 1 before the surface point of the roller 13 closest to the cutting device. The cutting knife 11 is then pivoted in the tape running direction and thereby reaches the point of the roller 13 closest to the cutting device 12. As soon as the cutting device 12 pulls the cutting knife 11 back against the direction of the arrow 15, a pivoting return spring 19 ensures that the cutting knife 11 around the Pendulum axis 14 pivots back into the starting position.
Zwischen Rolle 13 und Andruckrolle 10 sind neben dem Band 1 noch Seitenführungsrollen 20 vorgesehen. Im Bereich der Führungsrolle 7 ist noch eine zusätzliche Klemmvorrichtung 21 angeordnet, mit welcher das Band 1 auch im Bereich der Führungsrolle 7 festgeklemmt werden kann.In addition to the belt 1, side guide rollers 20 are also provided between the roller 13 and the pressure roller 10. An additional clamping device 21 is arranged in the area of the guide roller 7, with which the band 1 can also be clamped in the area of the guide roller 7.
Durch einen Klebebandsensor 22 kann der geschnittene Anfang eines Klebebandtrums auf der Peripherie der Andruckrolle 10 festgestellt werden, so daß für erneute Klebevorgänge exakte Klebebandpositionierungen möglich sind. The cut start of an adhesive tape strand on the periphery of the pressure roller 10 can be determined by an adhesive tape sensor 22, so that exact adhesive tape positioning is possible for renewed adhesive operations.
