Description

Die Erfindung betrifft eine Vorrichtung zum Durchtrennen eines Klebebandes gemäß dem Oberbegriff des Anspruchs 1 und ein Verfahren zur Vorbereitung einer Klebestelle gemäß den Merkmalen des Anspruchs 10.The invention relates to a device for severing an adhesive tape according to the The preamble of claim 1 and a method for preparing a splice according to the features of claim 10.

Derartige Vorrichtungen werden beispielsweise, jedoch keineswegs ausschließlich, in Vorrichtungen eingesetzt, in denen die Papierrollen für einen Rollenwechsel in einer Rollenrotationsdruckmaschine vorbereitet werden. Bei der Rollenvorbereitung wird der Bahnanfang der neuen Rolle mit speziellen, zweiseitig haftenden Klebebändern am Umfang der Papierrolle fixiert. Eine Vorrichtung zum Vorbereiten einer Materialbahn, insbesondere einer Papierbahn, für den Rollenwechsel mit einer Vorrichtung zum Fördern und Durchtrennen eines Klebebandes ist beispielsweise in der WO 98 52 857 A1 beschrieben.Such devices are, for example, but not exclusively, in Used devices in which the paper rolls for a roll change in a Web-fed rotary printing press. In the role preparation is the Web start of the new roll with special adhesive tapes on two sides Fixed scope of paper roll. A device for preparing a material web, in particular a paper web, for the roll change with a device for conveying and cutting an adhesive tape is for example in WO 98 52 857 A1 described.

Mittels eines Planklebekopfs kann beispielsweise das zweiseitige Klebeband abgespult und das einseitig anhaftende Abdeckband vor der eigentlichen Klebezone abgezogen werden. Zur Durchtrennung des Klebebandes ist eine verstellbar angeordnete Klinge vorgesehen, deren Schneide quer zur Längsachse des Klebebandes am Klebeband zum Eingriff gebracht werden kann, so dass das Klebeband bei ausreichendem Vorschub der Klinge durchtrennt wird. Bei dieser bekannten Vorrichtung wird das Abdeckband bereits so früh in der Vorrichtung vom Klebeband abgezogen, dass es beim Durchtrennen des Klebebandes nicht mehr am Klebeband anliegt. Im Ergebnis folgt daraus, dass das Schnittende des Klebebandes, das nach dem Durchtrennen in der Vorrichtung verbleibt, an beiden Seiten mit der adhäsiven Haftschicht offen liegt. Dadurch können die Haftschichten leicht verschmutzen, beispielsweise durch Aufbringung von Staub, so dass bei der Anbringung des Schnittendes an der nächsten vorzubereitenden Papierrolle Störungen auftreten können.By means of a plane head, for example, the two-sided adhesive tape can be unwound and deducted the one-sided adhesive masking tape in front of the actual adhesive zone become. For the separation of the adhesive tape is an adjustable arranged blade provided, the cutting edge transverse to the longitudinal axis of the adhesive tape on the tape for Intervention can be brought, so that the adhesive tape with sufficient advance of the Blade is severed. In this known device, the cover tape is already peeled off from the adhesive tape so early in the device that it breaks when cutting Tape no longer rests on the tape. As a result it follows that the Cut end of the adhesive tape remaining in the device after severing, is exposed on both sides with the adhesive adhesive layer. This allows the Easily contaminate adhesive layers, for example by application of dust, so that when attaching the cut end to the next roll of paper to be prepared Faults can occur.

Die DE 43 15 539 C2 beschreibt eine Vorrichtung zum Schneiden einer Deckfolie eines laminierten Folienmaterials, wobei mittels eines Schallfeldes die Eindringtiefe eines Schneidwerkzeuges geregelt wird.DE 43 15 539 C2 describes a device for cutting a cover sheet of a laminated foil material, wherein by means of a sound field, the penetration depth of a Cutting tool is regulated.

Die DE 36 13 979 C2 offenbart Rundmesser zum Ausschneiden eines mehrlagigen Klebebandes.DE 36 13 979 C2 discloses circular blade for cutting a multilayer Tape.

Durch die EP 1 041 131 A1 ist eine Schneideinrichtung für Klebeband mittels Rundmesser bekannt. Der Antrieb der Rundmesser erfolgt über eine motorisch angetriebene Gegenwalze, die auch als Abstützung für die Rundmesser wirkt.EP 1 041 131 A1 discloses a cutting device for adhesive tape Round knife known. The rotary knives are driven by a motor driven counter-roller, which also acts as a support for the circular blade.

Die EP 0 755 890 A1 zeigt eine Vorrichtung zum Schneiden von doppelseitigem Klebeband auf einer Trägerfolie. Dabei wird ein gefedertes Schneidmesser quer zur Transportrichtung des Klebebandes transportiert, wobei sich das Schneidmesser auf dem Trägerband des Klebebandes abstützt.EP 0 755 890 A1 shows a device for cutting double-sided Adhesive tape on a carrier foil. This is a spring-loaded cutting across the Transported transport direction of the adhesive tape, wherein the cutting blade on the Carrier tape of the adhesive tape supports.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Durchtrennen eines Klebebandes und ein Verfahren zur Vorbereitung einer Klebestelle zu schaffen.The invention is based on the object, a device for severing a To create adhesive tape and a method for preparing a splice.

Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 oder 10 gelöst.The object is achieved by the features of claims 1 or 10.

Ein Vorteil der Vorrichtung liegt insbesondere darin, dass die Schneideinrichtung zum Durchtrennen des Klebebandes derart ausgebildet ist, dass beim Durchtrennen des Klebebandes eine Verbindung des am Klebeband noch anliegenden Abdeckbandes über die Schnittzone hinweg erhalten bleibt. Das bedeutet mit anderen Worten, dass das Klebeband zusammen mit dem noch anliegenden Abdeckband in die Schnittzone eingefördert wird, wobei bei Eingriff der Schneideinrichtung am Klebeband nur das Klebeband vollständig durchtrennt wird, wohingegen das Abdeckband nicht durchtrennt wird, so dass eine Verbindung des Abdeckbandes über die Schnittzone hinweg erhalten bleibt. Dadurch kann erreicht werden, dass das Abdeckband auch nach Durchtrennung des Klebebandes an beiden Schnittenden anhaftet, so dass insbesondere die Haftschicht im Bereich des in der Vorrichtung verbleibenden Schnittendes durch das Abdeckband geschützt ist.An advantage of the device is in particular that the cutting device for Cutting the adhesive tape is formed such that when cutting the Adhesive tape a compound of the adhesive tape still applied masking tape over the cut zone is preserved. In other words, that means that Adhesive tape together with the remaining masking tape in the cutting zone is promoted, wherein upon intervention of the cutting device on the adhesive tape only the Adhesive tape is completely severed, whereas the masking tape is not severed so as to obtain a connection of the cover band across the cutting zone remains. This can be achieved that the masking tape after transection the adhesive tape adheres to both cut ends, so that in particular the adhesive layer in the region of the remaining in the device cut end by the masking tape is protected.

Nach einer bevorzugten Ausführungsform der Erfindung ist die Schneideinrichtung mit einem Rundmesser ausgestattet, an dessen Außenumfang eine Schneide vorgesehen ist. Dieses Rundmesser rollt beim Durchtrennen des Klebebandes mit seiner Schneide auf dem Klebeband ab und durchtrennt in einer Abwälzbewegung das Klebeband jeweils entsprechend dem Vorschub quer zum Klebeband. Die Schneidleistung kann dabei noch erhöht werden, wenn das Rundmesser mit einer Antriebseinrichtung rotatorisch angetrieben wird, so dass die Schneide nicht allein aufgrund der Abwälzbewegung, sondern zusätzlich aufgrund der Antriebsleistung der Antriebseinrichtung umläuft.According to a preferred embodiment of the invention, the cutting device with equipped a circular blade, on the outer circumference of a cutting edge is provided. This circular knife rolls when cutting the tape with its cutting edge the tape from and severed in a rolling movement, the tape each according to the feed across the tape. The cutting performance can still be increased when the circular blade with a drive device rotatory is driven, so that the cutting edge not only due to the rolling movement, but additionally rotates due to the drive power of the drive device.

Um ein Durchtrennen des Klebebandes unter gleichzeitiger Erhaltung einer Verbindung des Abdeckbandes über die Schnittzone hinweg gewährleisten zu können, wird die Schneideinrichtung beim Durchtrennen des Klebebandes mit einer definierten Kraft am Klebeband in Eingriff gebracht. Diese Schneidkraft wird dann derart gewählt, dass zum einen ein sicheres Durchtrennen des Klebebandes gewährleistet ist, wobei zugleich die eingestellte Schneidkraft nicht zum Durchtrennen des Abdeckbandes ausreicht. Konstruktiv kann dies beispielsweise dadurch gelöst werden, dass die mit dem Klebeband während des Schneidens in Eingriff gebrachten Bauteile federnd gelagert sind oder mit einem pneumatischen Druckzylinder gegen das Klebeband gefahren werden.To cut through the tape while maintaining a connection To ensure the cover over the cutting zone away, is the Cutting device when cutting the tape with a defined force on Adhesive tape engaged. This cutting force is then chosen such that the a secure cutting of the adhesive tape is ensured, at the same time the set cutting force is not sufficient for cutting the masking tape. In terms of design, this can be achieved, for example, by using the adhesive tape during cutting brought into engagement components are resiliently mounted or with be driven against the tape a pneumatic pressure cylinder.

Nach dem Verfahren zur Anbringung und Abtrennung des Klebebandes wird das Klebeband mit der Seite an der Oberfläche der Klebestelle zur Anlage gebracht, die nach Abspulen des Klebebandes ohnehin offen liegt.After the method for attaching and separating the adhesive tape is the Adhesive tape with the side attached to the surface of the splice, which after Unwinding of the tape is already open.

Vom Klebebandabschnitt 02 ist das Abdeckband 12 vollständig abgezogen, wohingegen das Schnittende 24 des Klebebands 06 weiterhin am Abdeckband 12 anliegt, so dass die Klebeschicht geschützt ist Die Position des Schnittendes 24 nach Abheben der Fig. 2 illustrates the device 01 after reaching the end of the splice 03. Die Pressure roller 16 has been turned off, so that the tape section 02 completely separated from the adhesive tape 06 by the use of the cutting device 08 formed cut ends 23 and 24 are completely separated from each other. from Tape section 02, the cover tape 12 is completely removed, whereas the Cut end 24 of the adhesive tape 06 continues to abut the cover strip 12, so that the Adhesive layer is protected The position of the cut end 24 after lifting the

Andruckwalze 16 ist exakt bestimmt, so dass das Schnittende 24 bei Anbringung des Klebebands 06 an einer nächsten Klebestelle 03 relativ genau positioniert werden kann. Außerdem wird das Schnittende 24 durch Anhaften am Abdeckband 12 exakt geführt.Pressure roller 16 is determined exactly, so that the cut end 24 when attaching the Adhesive tape 06 can be positioned relatively accurately at a next splice 03. In addition, the cut end 24 is accurately guided by adhesion to the cover strip 12.

Die Funktion der Schneideinrichtung 08 beim Durchtrennen des mehrschichtigen Klebebandes 06 ist in Fig. 3 schematisch dargestellt. Das Rundmesser 21 ist in vier Schritten schematisch dargestellt, wobei das Rundmesser 21 in Schritt zwei bis vier strichpunktiert dargestellt ist. Ausgehend von einer abgestellten Grundstellung des Rundmessers 21 wird das Rundmesser 21 zum Durchtrennen des Klebebands 06 zunächst entsprechend dem Bewegungspfeil 26 an das Auflageelement 22 angestellt, so dass die umlaufende Schneide 27 des Rundmessers 21 auf der Oberfläche des Auflageelements 22 anliegt. Danach wird das Rundmesser 21 in einer linearen Vorschubbewegung in Richtung des Bewegungspfeils 28 rechtwinklig - was jedoch nicht innerhalb der beanspruchten Erfindung füllt - oder schräg zur Längsachse (strichpunktiert dargestellt in Fig. 4) des Klebebandes 06 verfahren, wobei die Schneide 27 entsprechend dem Bewegungspfeil 29 um den Drehpunkt 31 des Rundmessers 21 rotiertThe function of the cutter 08 when cutting the multilayer Adhesive tape 06 is shown schematically in Fig. 3. The circular blade 21 is in four Steps shown schematically, wherein the circular blade 21 in step two to four dash-dotted lines is shown. Starting from a parked basic position of the Round knife 21 is the circular blade 21 for cutting the adhesive tape 06th initially adjusted according to the movement arrow 26 to the support element 22, so that the peripheral cutting edge 27 of the circular blade 21 on the surface of Support element 22 abuts. Thereafter, the circular blade 21 is in a linear Feed movement in the direction of the movement arrow 28 at right angles - which does not fill within the claimed invention - or obliquely to Longitudinal axis (shown in phantom in Fig. 4) of the adhesive tape 06 method, wherein the cutting edge 27 corresponding to the movement arrow 29 about the pivot point 31 of the Round knife 21 rotates

Dies wird dadurch erreicht, dass der eingestellte Druck das Rundmesser 21 und der Schneidwiderstand des Abdeckbandes 12 eine Durchtrennung des Abdeckbandes 12 verhindern. Sobald das Rundmesser 21 das Klebeband 06 vollständig durchtrennt hat, wird es gemäß dem Bewegungspfeil 32 abgestellt und gemäß dem Bewegungspfeil 33 in seine nicht dargestellte Grundstellung zurückgefahren.The circular blade 21 is eg resiliently mounted and is defined with a (preselectable) force pressed against the support element 22. This set Cutting force is just chosen so that when rolling the circular blade 21 on the Sticky tape 06 through the cutting edge 27 cuts through all layers of the adhesive tape 06 whereas a connection of the masking tape 12 over that in the image plane extending cutting zone 19 is maintained. This is achieved by the fact that the set pressure the circular blade 21 and the cutting resistance of the cover strip 12th prevent a separation of the cover strip 12. Once the circular blade 21 the Sticky tape 06 has completely severed, it is according to the movement arrow 32nd turned off and according to the movement arrow 33 in its basic position, not shown scaled back.

Beim Schneiden ist außer dem zu schneidenden Klebeband kein wegbegrenzendes, z. B. die Schnitttiefe festlegendes Element, z. B. ein Anschlag vorhanden.When cutting is beyond the tape to be cut wegbegrenzendes, z. B. the cutting depth defining element, z. B. a stop available.

In Fig. 4 ist die Vorrichtung 01 mit dem Klebeband 06, den Umlenkwalzen 07, der Schneideinrichtung 08 und der Klebestelle 03 in Ansicht von vorne dargestellt. Beim Durchtrennen des Klebebands 06 wird das Rundmesser 21 aus der Grundstellung an das Auflageelement 22 angestellt und gemäß dem Bewegungspfeil 28 quer zum Klebeband 06 verfahren, bis das Klebeband 06 vollständig durchtrennt ist. Nach Erreichen dieser Endstellung auf der linken Seite des Auflageelements 22 wird das Rundmesser 21 wieder abgehoben und zurück in die Grundstellung verfahren.
