Description

Die Erfindung betrifft einen Rollenwechsler zum Verbinden von Anfangs- und Endstücken von Werkstoffbahnen in einer Vorrichtung zum Herstellen von Hygieneprodukten und umfasst weitere Merkmale gemäss Oberbegriff von Patentanspruch 1.The invention relates to a roll changer for connecting starting and ending pieces of material webs in a device for producing hygiene products and comprises further features according to the preamble of patent claim 1.

Ein Verfahren und eine Vorrichtung der hier interessierenden Art sind aus der EP 0 525 075 B1 grundsätzlich bekannt. So beschreibt diese Druckschrift ein Verfahren und eine Vorrichtung zum Verbinden von mindestens zwei einfach oder mehrfach geschichteten, luftdurchlässige sowie weiche Papierbahnen enthaltenden Werkstoffen. Verbunden werden die Werkstoffbahnen durch Verspleissen im Walzenspalt von zwei Prägewalzen. Gehalten wird das Anfangsstück der anzuschliessenden Werkstoffbahn zunächst mit Hilfe eines Saugkastens, dessen Haltekraft aufgehoben wird, wenn die Bahn an das Endstück der anderen Bahn angeschlossen werden soll.A method and a device of the type of interest here are basically known from EP 0 525 075 B1. Thus, this document describes a method and apparatus for joining at least two single or multiple layered, air-permeable and soft paper webs containing materials. The material webs are connected by splicing in the nip of two embossing rollers. The starting piece of the material web to be joined is first held by means of a suction box, the holding force of which is canceled when the web is to be connected to the end piece of the other web.

Problematisch ist es bei der bekannten Vorrichtung, dass dort mit einem sehr genau definierten Unterdruck gearbeitet werden muss. Die Unterdrucksteuerung ist daher schwierig. Auch ist nicht unproblematisch, dass das Endstück der einen Bahn Anfangsstück der anzuschliessenden Bahn mitziehen muss, obwohl beide vor dem Eintritt in den Walzenspalt der Prägewalzen mit Unterdruck auf einen Saugkasten gesaugt werden.It is problematic in the known device that there must be worked with a very well-defined negative pressure. The vacuum control is therefore difficult. Also is not There is no problem in that the end piece of the one web has to pull along the beginning piece of the web to be joined, although both are sucked onto a suction box with negative pressure before entering the nip of the embossing rolls.

Ferner sind Rollenwechsler der hier interessierenden Art aus der US-A-5039374 bekannt, die zum Verbinden von Anfangsstücken und von Endstücken von Werkstoffbahnen aneinander ebenfalls zum Herstellen von Hygieneprodukten dienen. Diese Rollenwechsler weisen zwei Prägewalzen und Träger für Bahnrollen sowie mindestens ein Trennelement bei jeder Prägewalze auf, wobei ferner das Anfangsstück einer neuer Werkstoffbahn an einer der beiden Prägewalzen fixierbar ist.Further, reelstands of the type of interest here are known from US-A-5039374, which also serve for the manufacture of sanitary products for joining initial pieces and end pieces of sheets of material to each other. These roll changers have two embossing rollers and carriers for web rolls and at least one separating element in each embossing roll, wherein furthermore the starting piece of a new material web can be fixed to one of the two embossing rolls.

Der Erfindung liegt gegenüber diesem Stand der Technik die Aufgabe zugrunde, die Voraussetzungen für einen möglichst einfachen und raschen Rollenwechsel zu schaffen, der sich mit einem nur geringen Arbeitsaufwand durchführen läßt.The invention is compared to this prior art, the task of creating the conditions for the simplest and quickest roll change, which can be carried out with only a small amount of work.

Zur Lösung dieser Aufgabe sieht die Erfindung mit den Merkmalen des kennzeichnenden Teiles von Patentanspruch 1 vor, dass mindestens eine der Prägewalzen antreibbar ist, dass mindestens eine Prägewalze auf die andere Prägewalze hin und von dieser weg bewegbar ist und dass jeweils ein bewegbar gelagertes Halte- und Führungselement für jede der Werkstoffbahnen in Laufrichtung vor den Prägewalzen angeordnet ist und jeweils eine Position zur Vorbereitung eines nächsten Spleissvorganges und eine Betriebsstellung aufweist.To solve this problem, the invention provides with the features of the characterizing part of claim 1, that at least one of the embossing rollers is driven, that at least one embossing roller on the other embossing roller and away from this is movable and that in each case a movably mounted holding and Guiding element for each of the material webs is arranged in the direction of travel in front of the embossing rollers and each having a position for preparing a next splicing operation and an operating position.

Während der Produktion bewegt sich die ablaufende Werkstoffbahn durch den Prägewalzenspalt, ohne eine Prägewalze zu berühren. Beide Prägewalzen sind daher während der Produktion stillgesetzt. Erfindungsgemäß wird das Anfangsstück der anzuschliessenden Werkstoffbahn unmittelbar an einer der beiden stillstehenden Prägewalzen fixiert. Beide Prägewalzen weisen zu diesem Zweck vor zugsweise eine Saugleiste bzw. eine Reihe von Saugöffnungen auf und sind an Unterdruckleitungen anschliessbar.During production, the running material web moves through the embossing nip without touching an embossing roll. Both embossing rollers are therefore stopped during production. According to the invention, the starting piece of the material web to be joined is fixed directly on one of the two stationary embossing rolls. Both embossing rollers have for this purpose before preferably a squeegee or a series of suction ports and are connected to vacuum lines.

Zum Verbinden der Werkstoffbahnen werden die beiden Prägewalzen aneinander gedrückt und in Drehung versetzt. Dabei verbinden sich die beiden Werkstoffbahnen durch Druck und Verformung nach Art einer Spleissverbindung, wobei das Endstück der einer Werkstoffbahn nach dem Herstellen der Spleissverbindung noch abgetrennt wird.To connect the material webs, the two embossing rollers are pressed against each other and rotated. In this case, the two material webs connect by pressure and deformation in the manner of a splice, wherein the tail of a web of material after the production of the splice connection is still separated.

Die besagten Maßnahmen lassen sich gut vorbereiten. Der eigentliche Spleissvorgang lässt sich dann sicher und zuverlässig durchführen. Die Folge ist ein schneller Rollenwechsel mit einem kurzfristigen Übergang von dem Ende einer Warkstoffbahn auf den Anfang der nächsten Werkstoffbahn.The said measures can be well prepared. The actual splicing process can then be carried out safely and reliably. The result is a fast roll change with a short-term transition from the end of a material web to the beginning of the next material web.

Weitere Merkmale der Erfindung gehen aus Unteransprüchen und der Beschreibung im Zusammenhang mit der Zeichnung hervor.Further features of the invention will become apparent from dependent claims and the description in conjunction with the drawings.

Ein Rollenwechsler 1 zum Verbinden eines Anfangsstückes 2 einer Werkstoffbahn 3 mit einem Endstück 4 einer anderen Werkstoffbahn 5 in einer Vorrichtung 6 zum Herstellen von Hygieneprodukten umfasst Träger 7 und 8 für Bahnrollen 9 und 10 sowie Prägewalzen 11 und 12, mit deren Hilfe das Anfangsstück 2 bei einem Durchgang durch einen Walzenspalt 40 zwischen den beiden Prägewalzen 11 und 12 an das Endstück 4 gedrückt wird. Beide Prägewalzen 11, 12 weisen nicht dargestellte Freidreheinrichtungen derart auf, dass die Prägewalze 11 nur in Richtung des Pfeiles 24 und die Prägewalze 12 nur in Richtung des Pfeiles 25 drehbar ist. Durch geeignete Rücklaufsperren ist die Prägewalze 11 somit in Fig. 2 nur im Uhrzeigersinn drehbar und die Prägewalze 12 ist nur entgegen dem Uhrzeigersinn drehbar.A reel changer 1 for connecting an initial piece 2 of a material web 3 with an end piece 4 of another material web 5 in a device 6 for the manufacture of hygiene products includes carriers 7 and 8 for web rolls 9 and 10 and embossing rolls 11 and 12, with the aid of the initial piece 2 at a passage through a nip 40 between the two embossing rollers 11 and 12 is pressed against the end piece 4. Both embossing rollers 11, 12 have not shown Freidreheinrichtungen such that the embossing roller 11 is rotatable only in the direction of the arrow 24 and the embossing roll 12 only in the direction of the arrow 25. By suitable backstops, the embossing roller 11 is thus rotatable in Fig. 2 only in a clockwise direction and the embossing roll 12 is rotatable only counterclockwise.

Die eine Prägewalze 11 ist auf die andere Prägewalze 12 hin und von dieser weg bewegbar. Dazu ist die Prägewalze 11 auf einem Träger 13 gelagert und zusammen mit dem Träger 13 um eine Achse 14 schwenkbar. Ein steuerbarer Antrieb 15 dient zum Verstellen und zum Fixieren des Trägers 13 in der Andruck- und Spleissposition der Prägewalze 11 (Fig. 2).One embossing roll 11 is movable toward and away from the other embossing roll 12. For this purpose, the embossing roller 11 is mounted on a carrier 13 and pivotable together with the carrier 13 about an axis 14. A controllable drive 15 serves to adjust and fix the carrier 13 in the pressing and splicing position of the embossing roll 11 (FIG. 2).

Die andere Prägewalze 12 ist stationär gelagert. Ferner ist der Prägewalze 12 ein Antrieb 15' zugeordnet, mit dessen Hilfe nicht nur die Prägewalze 12 zwangsweise in Drehung versetzbar ist, sondern auch die in Richtung Prägewalze 12 gedrückte Prägewalze 11 beim Verspleissen der Werkstoffbahnen 3 und 5. Die angetriebene Prägewalze 12 nimmt beim Verspleissen die nicht selbst angetriebene Prägewalze 11 aufgrund von Reibschluss mit.The other embossing roller 12 is mounted stationary. Further, the embossing roller 12 is associated with a drive 15 ', by means of which not only the embossing roller 12 is forcibly set in rotation, but also the embossing roller 11 pressed in the direction of the embossing roller 12 during splicing of the material webs 3 and 5. The driven embossing roller 12 takes place during splicing the not self-driven embossing roller 11 due to frictional engagement with.

Die beiden Prägewalzen 11 und 12 sind in Fig. 3 in grösserem Maßstab dargestellt und lassen erkennen, dass jede Prägewalze 11, 12 ein Halteelement 16 für das Anfangsstück einer Werkstoffbahn aufweist. Gemäss Ausführungsbeispiel ist das Halteelement 16 eine Saugleiste bzw. umfasst eine Reihe von Saugöffnungen 16', die jeweils am Umfang 17 parallel zur Achse 18 einer jeden Prägewalze 11, 12 angeordnet sind. Über jeweils einen Saugkanal 19 mit einem Steuerfenster am einen stirnseitigen Ende einer jeden Prägewalze 11, 12 ist ferner eine luftleitende Verbindung zu einem Saug- und Steuerkanal 20 vorgesehen, der sich in einer stirnseitig neben der Prägewalze angeordneten, still stehenden Steuerscheibe bogenförmig längs der Bewegungsbahn des Saugkanals 19 bzw. Steuerfensters erstreckt. Die Saug- und Steuerkanäle 20 in den beiden Steuerscheiben sind gemäss Fig. 3 aufeinanderzu gerichtet und erstrecken sich jeweils über etwa 90 Grad und enden auf gleicher Höhe etwa an einer Verbindungslinie 21 zwischen den beiden Achsen 18.The two embossing rollers 11 and 12 are shown in Fig. 3 on a larger scale and can be seen that each embossing roll 11, 12 has a holding element 16 for the initial part of a material web. According to the exemplary embodiment, the holding element 16 is a suction strip or comprises a series of suction openings 16 'which are arranged in each case on the circumference 17 parallel to the axis 18 of each embossing roll 11, 12. In each case via a suction channel 19 with a control window at one end face of each embossing roller 11, 12 an air-conducting connection to a suction and control channel 20 is also provided, which in a front side next to the embossing roller arranged stationary control disc arcuately along the trajectory of Suction channel 19 and control window extends. The suction and control channels 20 in the two control discs are directed towards each other as shown in FIG. 3 and each extend over about 90 degrees and end at the same height approximately at a connecting line 21 between the two axes 18th

Ferner sind die beiden bogenförmigen Saug- und Steuerkanäle 20 an jeweils eine Unterdruckleitung 22 angeschlossen, die je nach Betriebszustand keine bzw. die eine oder die andere Prägewalze 11, 12 im Bereich der Saugöffnungen 16' mit Unterdruck versorgt.Furthermore, the two arcuate suction and control channels 20 are connected to a respective vacuum line 22 which, depending on the operating state, supplies none or one or the other embossing roll 11, 12 in the region of the suction openings 16 'with negative pressure.

Der Rollenwechsler 1 umfasst ferner Halte- und Führungselemente 30 und 31, die einerseits während des normalen Betriebes und andererseits beim Vorbereiten und Herstellen einer Spleissverbindung wirksam sind. Sie sind um jeweils eine Achse 32 bzw. 33 mit Hilfe von Antrieben 34, 35 schwenkbar gelagert und im wesentlichen symmetrisch zu den beiden Prägewalzen 11, 12 angeordnet.The roll changer 1 further comprises holding and guiding elements 30 and 31 which are effective on the one hand during normal operation and on the other hand in preparing and producing a splice connection. They are pivotally mounted about an axis 32 and 33 by means of drives 34, 35 and arranged substantially symmetrically to the two embossing rollers 11, 12.

An ihrem Umfang weist jedes Halte- und Führungselement 30, 31 mindestens ein Umlenkelement 26 bzw. 36 und gemäss Ausführungsbeispiel jeweils zwei Umlenkelemente 26, 27 bzw. 36, 37 für die jeweilige Werkstoffbahn 3 bzw. 5 auf. Zusammen mit den Schwenkachsen 32, 33 und den Umlenkelementen 26, 27 bzw. 36, 37 bilden die Halte- und Führungselemente 31, 32 jeweils annähernd Dreiecke.At its periphery, each holding and guiding element 30, 31 has at least one deflecting element 26 or 36 and, according to the exemplary embodiment, two deflecting elements 26, 27 and 36, 37 for the respective material web 3 and 5, respectively. Together with the pivot axes 32, 33 and the deflection elements 26, 27 and 36, 37, the holding and guiding elements 31, 32 each approximately triangles.

Gemäss der Darstellung in Fig. 2 dient die Werkstoffbahn 5 zur Produktion von Teilen. Die permanent ablaufende Werkstoffbahn 5 wird dabei über das Halte- und Führungselement 31 geführt, das hierbei hoch geschwenkt ist. Die Werkstoffbahn 5 läuft von einem stationär angeordneten Umlenkelement 41 zu den Umlenkelementen 26 und 27 am Umfang des Halte- und Führungselementes 31 und sodann kontaktfrei durch den Walzenspalt 40 zu weiteren Umlenkelementen 42 und 43 usw.. Die Betriebsstellung des Halte- und Führungselementes 31 mit seinem Umlenkelement 26 vor dem Walzenspalt 40 und die Lage des Umlenkelementes 42 hinter dem Walzenspalt 40 sind grundsätzlich derart gewählt, dass der normale, betiebsmässige Durchlauf der Werkstoffbahn 5 ohne Kontakt mit den Prägewalzen 11 oder 12 erfolgt.As shown in FIG. 2, the web of material 5 is used to produce parts. The permanently running web of material 5 is guided over the holding and guiding element 31, which in this case is pivoted upwards. The web of material 5 runs from a stationary arranged deflection element 41 to the deflecting elements 26 and 27 on the periphery of the holding and guiding element 31 and then contactless through the nip 40 to further deflecting elements 42 and 43, etc .. The operating position of the holding and guiding element 31 with his Deflection element 26 in front of the nip 40 and the position of the deflecting element 42 behind the nip 40 are basically chosen such that the normal, betiebsmässig passage of the web 5 is made without contact with the embossing rollers 11 or 12.

Während der Produktion mit der Werkstoffbahn 5 ist die Prägewalze 11 zur Erzeugung eines möglichst breiten Prägewalzenspaltes 40 aus ihrer Prägeposition heraus (entgegen dem Uhrzeigersinn in Fig. 2) sowie von der Prägewalze 12 weg bewegt. Die Werkstoffbahn 5 läuft daher zwischen dem Umlenkelement 26 und dem Umlenkelement 42 berührungsfrei durch den geöffneten Prägewalzenspalt 40. Gleichzeitig ist das Halte- und Führungselement 30 zur Vorbereitung des nächsten Spleissvorganges mit dem Anfangsstück 2 der Werkstoffbahn 3 in eine horizontale Position geschwenkt (Fig. 2).During production with the material web 5, the embossing roll 11 is moved away from its embossing position (counterclockwise in FIG. 2) and away from the embossing roll 12 in order to produce the largest possible embossing nip 40. The web of material 5 therefore passes without contact between the deflecting element 26 and the deflecting element 42 through the opened embossing nip 40. At the same time, the holding and guiding element 30 is pivoted into a horizontal position in preparation for the next splicing operation with the starting piece 2 of the material web 3 (FIG. 2). ,

Die neue Werkstoffbahn 3 wird mit ihrem Anfangsstück 2 zur Vorbereitung eines Spleissvorganges über die Umlenkelemente 38 und 36 gezogen und mit Hilfe des Halteelementes 16 bzw. der Saugöffnungen 16' an der Prägewalze 11 fixiert. Dazu werden die Saugöffnungen 16' an der Prägewalze 11 mit Unterdruck beaufschlagt, während die Saugluft an der Prägewalze 12 abgeschaltet bleibt.The new material web 3 is drawn with its initial piece 2 in preparation for a splicing process over the deflecting elements 38 and 36 and fixed to the embossing roll 11 with the aid of the holding element 16 or the suction openings 16 '. These are the Suction openings 16 'applied to the embossing roller 11 with negative pressure, while the suction air is switched off at the embossing roll 12.

Die Prägewalze 11 wird sodann im Uhrzeigersinn bzw. in Richtung des Pfeiles 24 um etwa 90 ° weitergedreht, bis das Anfangsstück 2 sicher im geöffneten Prägewalzenspalt 40 plaziert ist.The embossing roller 11 is then further rotated clockwise or in the direction of arrow 24 by about 90 ° until the initial piece 2 is placed securely in the open embossing nip 40.

Sodann wird das Halte- und Führungselement 30 mit Hilfe des Antriebes 34 in eine Abrollposition hoch geschwenkt (Fig. 2). Durch den in der Prägewalze 11 integrierten Freilauf wird dabei ein Zurückdrehen der Prägewalze 11 verhindert. Die Werkstoffbahn 3 wird gleichzeitig von der Bahnrolle 9 nachgezogen.Then, the holding and guiding element 30 is pivoted up by means of the drive 34 in a roll-off position (Fig. 2). By integrated in the embossing roller 11 freewheel while turning back the embossing roller 11 is prevented. The material web 3 is simultaneously drawn by the web roll 9.

Sodann wird die Prägewalze 11 mit Hilfe des Antriebes 15 in Richtung auf die Prägewalze 12 bewegt, wobei das Anfangsstück 2 der Werkstoffbahn 3 an die Werkstoffbahn 5 angepresst wird. Gleichzeitig wird die Prägewalze 12 mit Hilfe ihres Antriebes 15' in Richtung des Pfeiles 25 in Drehung versetzt, wobei die Prägewalze 11 in Richtung des Pfeiles 24 mitgedreht wird und die Werkstoffbahnen 3 und 5 miteinander verprägt werden. Unmittelbar nach Beginn der Drehung der Prägewalze 11 wird der an ihren Saugöffnungen 16' herrschende Unterdruck unterbrochen und an dem Halte- und Führungselement 31 wird das Endstück 4 vom Rest 44 der Werkstoffbahn 5 mit Hilfe eines Trennelementes 45 abgetrennt. Auch Einrichtungen 46 zum Halten der Werkstoffbahn während des Trennschnittes sind neben dem Trennelement 45 vorgesehen.Then, the embossing roller 11 is moved by means of the drive 15 in the direction of the embossing roll 12, wherein the starting piece 2 of the material web 3 is pressed against the material web 5. At the same time the embossing roll 12 is rotated by means of its drive 15 'in the direction of the arrow 25 in rotation, wherein the embossing roller 11 is rotated in the direction of arrow 24 and the material webs 3 and 5 are embossed with each other. Immediately after the start of the rotation of the embossing roll 11, the negative pressure prevailing at its suction openings 16 'is interrupted and at the holding and guiding element 31 the end piece 4 is separated from the remainder 44 of the material web 5 with the aid of a separating element 45. Also means 46 for holding the web of material during the separating cut are provided adjacent to the separating element 45.

Sobald das Endstück 4 mit der neuen Werkstoffbahn 3 verprägt ist, wird die Prägewalze 11 wieder von der Prägewalze 12 entfernt, so dass ein breiter Prägewalzenspalt 14 zwischen ihnen entsteht. Gleichzeitig wird der Antrieb 15' stillgesetzt. Die neue Werkstoffbahn 3 läuft nun zwischen den Umlenkelementen 36 und 42 berührungsfrei durch den Spalt 40.As soon as the end piece 4 is embossed with the new material web 3, the embossing roll 11 is removed again from the embossing roll 12, so that a broad embossing nip 14 is created between them. At the same time, the drive 15 'is stopped. The new material web 3 now passes between the deflecting elements 36 and 42 without contact through the gap 40.

Das Halte- und Führungselement 31 wird danach in seine horizontale Position zurückgeschwenkt und macht so den Weg frei für die Vorbereitung einer neuen Bahnrolle 10, deren Bahnanfang in gleicher Weise durch Verprägen mit dem Bahnende der Werkstoffbahn 3 verbunden wird, wenn diese Bahn abgearbeitet ist.The holding and guiding element 31 is then pivoted back into its horizontal position and thus clears the way for the Preparation of a new web roll 10 whose web start is connected in the same way by embossing with the web end of the material web 3, when this web is processed.

Entsprechend den unterschiedlichen Anforderungen befinden sich die beiden Halte- und Führungselemente 30 bzw. 31 in unterschiedlichen Positionen und sind - bezogen auf die durch den Prägewalzenspalt 40 definierte Ebene- aufeinanderzu und voneinanderweg bewegbar. Während des Betriebes steht das eine Halte- und Führungselement 31 im wesentlichen senkrecht, während das andere Halte- und Führungselement in eine annähernd horizontale Position geschwenkt ist.According to the different requirements, the two holding and guiding elements 30 and 31 are in different positions and are - with respect to the defined by the embossing nip 40 level - each other and movable away from each other. During operation, one holding and guiding element 31 is substantially vertical, while the other holding and guiding element is pivoted into an approximately horizontal position.

Die Umlenkelemente 36 bis 38 können ebenso wie die anderen Umlenkelemente 41 bis 43 jeweils Umlenkrollen sein.The deflecting elements 36 to 38, like the other deflecting elements 41 to 43, may each be deflecting rollers.

Über eine grundsätzlich bekannte Spanneinrichtung 47 mit einer Umlenkrolle 48 wird die Werkstoffbahn der Vorrichtung 6 für die Produktion zugeführt.About a basically known clamping device 47 with a guide roller 48, the material web of the device 6 is supplied for production.
