Vorrichtung zum Durchtrennen eines Klebebandes und Verfahren zur Vorbereitung einer KlebestelleDevice for severing an adhesive tape and method for preparing a splice
Die Erfindung betrifft eine Vorrichtung zum Durchtrennen eines Klebebandes und Verfahren zur Vorbereitung einer Klebestelle gemäß dem Oberbegriff der Ansprüche 1 oder 13.The invention relates to a device for severing an adhesive tape and method for preparing a splice according to the preamble of claims 1 or 13.
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 used, for example, but by no means exclusively, in devices in which the paper rolls are prepared for a roll change in a web-fed rotary printing press. During roll preparation, the web start of the new roll is fixed to the circumference of the paper roll with special double-sided adhesive tapes. An apparatus for preparing a material web, in particular a paper web, for the roll change with a device for conveying and severing an adhesive tape is described for example in WO 98 52 857 A1.
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 flat head, for example, the two-sided adhesive tape can be unwound and the masking tape adhering to one side can be removed before the actual adhesive zone. For cutting through the adhesive tape, an adjustably arranged blade is provided, the cutting edge of which can be brought into engagement with the adhesive tape across the longitudinal axis of the adhesive tape, so that the adhesive tape is severed when the blade is sufficiently advanced. In this known device, the cover tape is already removed from the adhesive tape so early in the device that it no longer rests on the adhesive tape when cutting the adhesive tape. As a result, it follows that the cut end of the adhesive tape remaining in the device after being severed is exposed on both sides with the adhesive adhesive layer. As a result, the adhesive layers can be easily contaminated, for example by the application of dust, so that when attaching the cut end to the next paper roll to be prepared Faults can occur.
Die DE 43 15539 C2 beschreibt eine Vorrichtung zum Schneiden einer Deckfolie eines laminierten Folienmaterials, wobei mittels eines Schallfeldes die Eindringtiefe eines Schneidwerkzeuges geregelt wird.DE 43 15539 C2 describes a device for cutting a cover film of a laminated film material, wherein by means of a sound field, the penetration depth of a cutting tool is controlled.
Die DE 36 13 979 C2 offenbart Rundmesser zum Ausschneiden eines mehrlagigen Klebebandes.DE 36 13 979 C2 discloses circular blade for cutting a multi-layer adhesive tape.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Durchtrennen eines Klebebandes und ein Verfahren zur Vorbereitung einer Klebestelle zu schaffen.The invention has for its object to provide a device for cutting an adhesive tape and a method for preparing a splice.
Die Aufgabe wird erfindungsgemäß durch die Merkmale der Ansprüche 1 oder 13 gelöst.The object is achieved by the features of claims 1 or 13.
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 severing the adhesive tape is designed in such a way that, when the adhesive tape is severed, a connection of the masking tape still present on the adhesive tape is maintained across the cutting zone. In other words, this means that the adhesive tape is conveyed into the cutting zone together with the masking tape still lying on it, whereby only the adhesive tape is completely severed when the cutting device engages with the adhesive tape, whereas the masking tape is not severed, so that a connection of the cover tape over the Intersection zone is maintained. It can thus be achieved that the cover tape also adheres to both cut ends after the adhesive tape has been cut through, so that in particular the adhesive layer is protected by the cover tape in the area of the cut end remaining in the device.
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 KlebeÖand 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 is equipped with 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 adhesive tape and cuts in a rolling movement, the adhesive tape each corresponding to the feed across the tape. The cutting performance can be further increased if the circular blade is driven in rotation with a drive device, so that the cutting edge rotates not only due to the rolling movement, but in addition 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, ist es besonders vorteilhaft, wenn die Schneideinrichtung beim Durchtrennen des Klebebandes mit einer definierten Kraft am Klebeband in Eingriff gebracht wird. 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.In order to be able to ensure a severance of the adhesive tape while at the same time maintaining a connection of the cover tape over the cutting zone, it is particularly advantageous if the cutting device is engaged with a defined force on the adhesive tape when the adhesive tape is severed. This cutting force is then selected such that on the one hand a secure cutting of the adhesive tape is ensured, at the same time the set cutting force is not sufficient for severing the masking tape. In terms of design, this can be achieved, for example, by the components which are brought into engagement with the adhesive tape during cutting being resiliently mounted or driven against the adhesive tape with 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 attachment and removal of the adhesive tape, the adhesive tape is brought to the side of the surface of the splice to the plant, which is already open after unwinding of the tape.

Durch Vorschub der Vorrichtung 01 in Richtung des Bewegungspfeils 14 wird dann fortlaufend das Klebeband 06 auf der Klebestelle 03 aufgeklebt, wobei das Abdeckband 12 nach Anbringung des Klebebandes 06 durch Einsatz einer Umlenkwalze 17 und einer entsprechend dem Vorschub der Vorrichtung 01 angetriebenen Aufwickeleinrichtung 18 vom Klebeband 06 abgezogen wird.03 brought into engagement, so that the attached on the side 13 of the adhesive tape 06 adhesive layer adheres to the splice 03. By advancing the device 01 in the direction of the movement arrow 14, the adhesive tape 06 is then continuously adhered to the splice 03, wherein the cover strip 12 after attachment of the adhesive tape 06 is deducted from the adhesive tape 06 by using a guide roller 17 and a corresponding to the feed of the device 01 driven take-up device 18.
Damit der Klebebandabschnitt 02 in der richtigen Länge vom Klebeband 06 abgelängt werden kann, wird die Vorrichtung 01 vor Erreichen des Endes der Klebestelle 03 in einem bestimmten Abstand z. B. angehalten, aber auch beim Verfahren der Vorrichtung 01 kann durchtrennt werden. Dieser Abstand entspricht gerade der Länge des Klebebandes 06 zwischen der Klebezone 09 und einer Schnittzone 19, in der das Klebeband 06 durch Eingriff eines Rundmessers 21 abgetrennt werden kann. Fig. 1 stellt die Vorrichtung 01 gerade in dem Zustand dar, in dem das Rundmesser 21 durch Zustellung am Klebeband 06 in Eingriff gebracht wird.Thus, the tape portion 02 can be cut to length in the correct length of the adhesive tape 06, the device 01 before reaching the end of the splice 03 at a certain distance z. B. stopped, but also in the process of the device 01 can be severed. This distance corresponds exactly to the length of the adhesive tape 06 between the adhesive zone 09 and a cutting zone 19, in which the adhesive tape 06 can be separated by engagement of a circular blade 21. Fig. 1 illustrates the device 01 in the state in which the circular blade 21 is brought into engagement by means of the adhesive tape 06.
Dem Rundmesser 21 gegenüberliegend ist in der Schneideinrichtung 08 ein Auflageelement 22 vorgesehen, so dass bei Zustellung des Rundmessers 21 das Klebeband 06 zwischen dem Rundmesser 21 und dem Auflageelement 22 verläuft. Durch Vorschub des Rundmessers 21 quer zur Längsachse des Klebebandes 06 (siehe Fig. 3) und gleichzeitigen Vorschub des Klebebandes 06 wird das Klebeband 06 vollständig und gerade (90°) durchtrennt, wohingegen am Abdeckband 12 eine Materialverbindung über die Schnittzone 19 hinweg erhalten bleibt. Die Vorrichtung 01 wird solange in Richtung des Bewegungspfeils 14 erfahren, bis der Klebebandabschnitt 02 vollständig an der Klebestelle 03 angebracht ist.The circular blade 21 opposite a support element 22 is provided in the cutting device 08, so that upon delivery of the circular blade 21, the tape 06 between the circular blade 21 and the support element 22 extends. By feeding the circular blade 21 transversely to the longitudinal axis of the adhesive tape 06 (see FIG. 3) and simultaneous feed of the adhesive tape 06, the adhesive tape 06 is severed completely and straight (90 °), whereas on the cover 12, a material connection is maintained across the cutting zone 19. The device 01 is experienced as long as in the direction of the movement arrow 14 until the tape portion 02 is completely attached to the splice 03.
Fig. 2 stellt die Vorrichtung 01 nach Erreichen des Endes der Klebestelle 03 dar. Die Andruckwalze 16 wurde nach oben abgestellt, so dass der Klebebandabschnitt 02 vollständig vom Klebeband 06 abgetrennt ist. Die durch Einsatz der Schneideinrichtung 08 gebildeten Schnittenden 23 und 24 sind vollständig voneinander getrennt. Vom Klebebandabschnitt 02 ist das Abdeckband 12 vollständig abgezogen, wohingegen das Schnittende 24 des Klebebands 06 weiterhin am Abdeckband 12 anliegt, so dass die Haftschicht geschützt ist. Die Position des Schnittendes 24 nach Abheben der 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.Fig. 2 illustrates the device 01 after reaching the end of the splice 03. The pressure roller 16 has been turned off, so that the tape portion 02 is completely separated from the adhesive tape 06. The cut ends 23 and 24 formed by use of the cutter 08 are completely separated from each other. From the tape portion 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 cutting end 24 after lifting the Pressure roller 16 is precisely determined so that the cut end 24 can be positioned relatively accurately when attaching the adhesive tape 06 to 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 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 rotiert.The function of the cutting device 08 when severing the multilayer adhesive tape 06 is shown schematically in FIG. The circular blade 21 is shown schematically in four steps, wherein the circular blade 21 is shown in phantom in steps two to four. Starting from a parked basic position of the circular blade 21, the circular blade 21 is first employed for severing the adhesive tape 06 according to the movement arrow 26 to the support element 22, so that the peripheral cutting edge 27 of the circular blade 21 rests on the surface of the support element 22. Thereafter, the circular blade 21 in a linear feed movement in the direction of the movement arrow 28 at right angles or obliquely to the longitudinal axis (dash-dotted lines in Fig. 4) of the adhesive tape 06, wherein the cutting edge 27 rotates according to the movement arrow 29 about the pivot point 31 of the circular blade 21.
Dabei ist die Neigung der Bewegungsrichtung 28 in Abhängigkeit von den Vorschubgeschwindigkeiten von Klebeband 06 und Rundmesser 21 derart festgelegt, dass ein gerader Schnittverlauf quer zur Längsrichtung des Klebebandes 06 erfolgt.In this case, the inclination of the direction of movement 28 as a function of the feed rates of adhesive tape 06 and circular blade 21 is set such that a straight cut is made transversely to the longitudinal direction of the adhesive tape 06.
Das Rundmesser 21 ist z. B. federnd gelagert und wird mit einer definierten (vorwählbaren) Kraft gegen das Auflageelement 22 gedrückt. Diese eingestellte Schneidkraft ist gerade so gewählt, dass beim Abwälzen des Rundmessers 21 über das Klebeband 06 durch die Schneide 27 alle Schichten des Klebebands 06 durchtrennt werden, wohingegen eine Verbindung des Abdeckbandes 12 über die in der Bildebene verlaufende Schnittzone 19 hinweg erhalten bleibt. 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 z. B. resiliently and is pressed with a defined (preselectable) force against the support element 22. This set cutting force is just chosen so that when rolling the circular blade 21 on the tape 06 through the cutting edge 27 all layers of the adhesive tape 06 are severed, whereas a compound of the cover strip 12 is maintained across the running in the image plane cutting zone 19 away. This is achieved in that the set pressure prevents the circular blade 21 and the cutting resistance of the cover strip 12, a transection of the cover strip 12. As soon as the circular blade 21 has completely severed the adhesive tape 06, it becomes, according to the movement arrow 32 parked and moved back according to the movement arrow 33 in its basic position, not shown.
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 depth of cut determining 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. In Fig. 4, the device 01 with the adhesive tape 06, the guide rollers 07, the cutter 08 and the splice 03 is shown in front view. When cutting the adhesive tape 06, the circular blade 21 is made from the basic position of the support member 22 and moved according to the movement arrow 28 across the tape 06 until the tape 06 is completely severed. After reaching this end position on the left side of the support element 22, the circular blade 21 is lifted again and moved back to the basic position.
