Description

Die Erfindung bezieht sich auf ein Verfahren zum Verbinden einer ersten, zu einer Verarbeitungsmaschine ablaufenden Materialbahn mit dem Anfang einer zweiten, aufgewickelten Materialbahn.The invention relates to a method for connecting a first material web running to a processing machine with the start of a second, wound material web.

Bei einem bekannten Verfahren nach der deutschen Offenlegungsschrift 2 129 903 wird die neue Materialbahn an einer bewegbaren Rolle befestigt, die mittels eines Laufwerkes in gegenüberliegende Position bezüglich einer Anschlagrolle verlagerbar ist, der entlang die erste Materialbahn vorbeibewegt wird. Die Reibung zwischen der sich bewegenden ablaufenden Materialbahn und der gegenüberliegenden Rolle hat zufolge, dass sich diese dreht, so dass die Vorderkante der neuen Materialbahn in Berührung mit der ablaufenden Materialbahn gelangt. Durch Klebemittel an der Aussenfläche der zweiten Materialbahn wird so eine Verbindung mit der ersten Materialbahn hergestellt. Nach dem Verbinden der beiden Materialbahnen wird dann die erste Materialbahn durchtrennt. Durch dieser Art der Verbindung entstehen während des Verbindungsvorganges Spannungen im Bahnmaterial, was zu Störungen des Verbindungsvorganges führt. Die in dieser Schrift beschriebene Vorrichtung mit den Merkmalen des Oberbegriffs des Patentanspruchs 3 beansprucht viel Platz, da von einer Doppelabrollung ausgegangen wird.In a known method according to German Offenlegungsschrift 2 129 903, the new web of material is fastened to a movable roller which can be displaced in an opposite position with respect to a stop roller which is moved along the first web of material by means of a running gear. The friction between the moving, running material web and the opposite roll has the result that it rotates, so that the front edge of the new material web comes into contact with the running material web. Adhesive on the outer surface of the second material web thus creates a connection with the first material web. After the two material webs have been connected, the first material web is then severed. This type of connection creates tensions in the web material during the connection process, which leads to malfunctions in the connection process. The device described in this document with the features of the preamble of claim 3 takes up a lot of space, since it is assumed that double unrolling.

Eine weitere Lösung geht aus der deutschen Auslegeschrift 2 430 514 hervor. Auch hier wird von einer Doppelabrollung ausgegangen, wobei die Materialbahnen in einem Laufwerkrahmen verschiebbar gelagerten Laufwerken zugeführt werden, die beidseitig einer mittleren Verbindungsstation angeordnet sind und auf diese verfahrbar bzw. von dieser wegbewegbar sind. Auch hier ist der Aufwand recht hoch und es ist viel Raum notwendig. Darüber hinaus muss das Verbindungsmittel z.B. ein Klebestreifen in der Maschine aufgebracht werden, was in der Regel jedoch besonders aufwendig ist.Another solution can be found in German publication 2 430 514. Here, too, double unwinding is assumed, the material webs being fed to drives which are mounted so as to be displaceable in a drive frame, which drives are arranged on both sides of a central connecting station and can be moved thereon or moved away therefrom. Again, the effort is quite high and a lot of space is required. In addition, the lanyard e.g. an adhesive strip can be applied in the machine, but this is usually particularly expensive.

Der Erfindung liegt die Aufgabe zugrunde, ein zum Verbinden einer ersten, ablaufenden Materialbahn mit dem Anfang einer zweiten, aufgewickelten Materialbahn geeignetes Verfahren vorzuschlagen, mit dem auf einfache und preisgünstige Weise in kürzester Zeit eine sichere Verbindung der beiden Materialbahnen erreicht werden kann. Ferner liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum vorzugsweise Durchführen des Verfahrens zu schaffen, die bei einfachem Aufbau vor allen Dingen noch universeller einsetzbar ist. Die schnelle Bahnverbindung wird erfindungsgemäss dadurch erreicht, dass die erste Materialbahn in Durchlaufrichtung gesehen hinter einem gespeicherten Bahnabschnitt bei stillstehender Verarbeitungsmaschine zunächst durchtrennt und darauf der abgetrennte Bahnabschnitt zumindest teilweise zwischengespeichert wird, wonach der Bahnabschnitt mit der zweiten Materialbahn in Druckkontakt gebracht wird und bei Anlauf der Verarbeitungsmaschine das Ende des zwischengespeicherten Bahnabschnitts und der zulaufende Anfang der zweiten Materialbahn durch Freigabe des zwischengespeicherten Bahnabschnittes miteinander verbunden werden.The invention is based on the object of proposing a method suitable for connecting a first, running material web to the start of a second, wound material web, with which a secure connection of the two material webs can be achieved in a simple and inexpensive manner in the shortest possible time. Furthermore, the invention is based on the object of providing a device for preferably carrying out the method which, above all, can be used more universally with a simple structure. The fast web connection is achieved according to the invention in that the first web of material, viewed in the direction of travel, is first cut behind a stored web section when the processing machine is at a standstill and the separated web section is then at least partially buffered, after which the web section is brought into pressure contact with the processing machine and when the processing machine starts up the end of the temporarily stored web section and the tapering start of the second material web are connected to one another by releasing the temporarily stored web section.

Mit den Mitteln nach der Erfindung kommt man zu einer Verbindung, wo das Verbindungselement, z.B. eine Klebung ausserhalb der Maschine auf die zulaufende Materialbahn aufgebracht werden kann und somit diese Materialbahn schon weitgehendst für die nachträgliche Verbindung vorbereitet werden kann. Die Verbindung lässt sich in äusserst kürzester Zeit herstellen und ist ausserdem recht preisgünstig, da auf eine aufwendige Doppelabrollung und jegliche Synchronisiereinrichtung verzichtet werden kann.With the means according to the invention a connection is obtained where the connecting element, e.g. an adhesive can be applied outside the machine to the incoming material web and thus this material web can be largely prepared for the subsequent connection. The connection can be established in a very short time and is also very inexpensive, since there is no need for complex double unrolling and any synchronization device.

In zweckmässiger Ausgestaltung der Erfindung ist vorgesehen, dass der zwischengespeicherte Bahnabschnitt zunächst aufgewickelt und nach dem Druckkontakt mit der zweiten Materialbahn wieder abgewickelt wird. Auf diese Weise kann die Verbindung auf engstem Raum untergebracht werden und zwar unabhängig davon, wie gross z.B. der Aussendurchmesser der die zweite Materialbahn aufweisenden Wickelrolle. Je nach Stellung bzw. Lage des Anfanges der zweiten Materialbahn wird ein entsprechend langes Stück des Endes der ersten Materialbahn zwischengespeichertund so abgewickelt, dass das Ende des zwischengespeicherten Bandabschnittes und der Anfang der zweiten Materialbahn im wesentlichen übereinander zu liegen kommen, so dass eine schnelle und sichere Verbindung möglich ist, ohne dass diese durch ein frei herunterhängendes Endstück der ersten Materialbahn beeinträchtigt wird.In an expedient embodiment of the invention it is provided that the temporarily stored web section is first wound up and unwound again after the pressure contact with the second material web. In this way, the connection can be accommodated in a confined space, regardless of how large, e.g. the outer diameter of the winding roll having the second material web. Depending on the position or location of the start of the second material web, a correspondingly long piece of the end of the first material web is temporarily stored and processed in such a way that the end of the temporarily stored tape section and the beginning of the second material web essentially lie one above the other, so that a quick and safe Connection is possible without this being impaired by a freely hanging end piece of the first material web.

Eine Vorrichtung zum Verbinden einer ersten, ablaufenden Materialbahn mit dem Anfang einer zweiten, von einer Ersatzwickelrolle zulaufenden Materialbahn umfasst einen die Ersatzwickelrolle tragenden Ständer und eine Speichereinrichtung zum Speichern eines Vorrats an Bahnmaterial sowie eine Schneideinrichtung zum Durchtrennen der Materialbahn, wobei erfindungsgemäss vorgesehen ist, dass in Bahnlaufrichtung zwischen der Schneideinrichtung und der Speichereinrichtung ein zumindest einen Teil eines abgetrennten Bahnabschnittes der ersten Materialbahn aufnehmendes Überführungsorgan angeordnet ist, das mit dem Aussenumfang der Ersatzwickelrolle in Druckkontakt bringbar ist. Mit den Mitteln der Erfindung kommt man zu einer einfachen Vorrichtung, insbesondere einer einfachen Zusatzvorrichtung für Reihenabrollungen, wobei eine Bahnverbindung mit dem Maschinenanlauf möglich ist. Dabei kann die Verbindung sowohl bei seitlicher als auch rückwärtiger Rollenzufuhr durchgeführt werden und zwar in kürzester Zeit.A device for connecting a first, running material web with the start of a second material web running in from a replacement winding roll comprises a stand carrying the replacement winding roll and a storage device for storing a supply of web material, as well as a cutting device for severing the web of material, according to the invention providing that in In the web running direction between the cutting device and the storage device there is arranged a transfer member which receives at least part of a separated web section of the first material web and which can be brought into pressure contact with the outer circumference of the replacement winding roll. With the means of the invention, a simple device is obtained, in particular a simple additional device for row unwinding, wherein a rail connection with the machine start-up is possible. The connection can be made with both side and rear roll feed and in a very short time.

Das ist insbesondere dann der Fall, wenn das Überführungsorgan als umlaufend angetriebene Saugwalze ausgebildet und an einem im Ständer gelagerten Schwenkarm angeordnet ist. Der Saugwalze kommt dabei die Aufgabe eines Zwischenspeichers vor, um das abgetrennte Endstück in einer entsprechenden Länge vorübergehend festzuhalten und zwar so lange, wie nach Kontaktdruck mit der Ersatzwickelrolle durch diese das aufgewickelte Bahnstück wieder abgewickelt wird, bis das Ende des zwischengespeicherten Bahnabschnittes mit dem mit einer Klebestelle versehenen Anfang der zweiten Materialbahn zusammenfällt.This is particularly the case when the transfer member is designed as a rotating suction roller and is arranged on a swivel arm mounted in the stand. The suction roll performs the task of a buffer to temporarily hold the separated end piece in a corresponding length, and for as long as the wound web piece is unwound again after contact pressure with the replacement winding roll until the end of the temporarily stored web section with the one Adhesive point provided at the beginning of the second material web coincides.

Von Bedeutung für die Erfindung ist auch das Merkmal, dass der Anlenkpunkt des Schwenkarms unmittelbar unterhalb der Speichereinrichtung und im wesentlichen oberhalb des max. Aussendurchmessers der Vorratsrolle angeordnet ist. Hierdurch werden die notwendigen Bauelemente auf engstem Raum untergebracht, so dass das Einbringen einer neuen Ersatzwickelrolle von der Seite oder von der Rückseite der Maschine her nicht beeinträchtigt wird. Das seitliche Einbringen der Ersatzwickelrolle wird dadurch erleichtert, dass zumindest einer von zwei gegenüberliegenden Tragbalken um eine im wesentlichen horizontale Achse schwenkbar ist. Hierdurch können alle Wickelrollendurchmesser aus der gleichen Position aufgenommen werden. Dabei kann die gesamte Bedienung vom Boden aus erfolgen, insbesondere das Bahneinführen. Ausserdem lassen sich solche Abrollungen komplett über Flur aufstellen, d.h. ohne aufwendige Fundamentarbeiten.Also of importance for the invention is the feature that the articulation point of the swivel arm is immediately below the storage device and essentially above the max. Outside diameter of the supply roll is arranged. As a result, the necessary components are accommodated in a very small space, so that the introduction of a new replacement winding roll from the side or from the rear of the machine is not impaired. The lateral insertion of the replacement winding roll is facilitated in that at least one of two opposite support beams can be pivoted about an essentially horizontal axis. As a result, all winding roll diameters can be accommodated from the same position. The entire operation can be carried out from the ground, in particular the web insertion. In addition, such unwinds can be set up completely over the hallway, ie without complex foundation work.

Die universelle Einsetzbarkeit der Vorrichtung wird erfindungsgemäss dadurch erreicht, dass die Vorrichtung bzw. mehrere unmittelbar aufeinander folgende Vorrichtungen zwischen den Ständern des Maschinengestells sowohl in als auch quer zur Laufrichtung der Materialbahnen eine Rollen-Beschickung bzw. -Entnahme aufweisen und dass der bzw. die der seitlichen Beschickung zugewandten Tragbalken des Tragrahmens hochschwenkbar sind. Mit den Mitteln nach der Erfindung kommt man zu einer Vorrichtung, bei der die Beschickung sowohl in als auch quer zur Bahnlaufrichtung erfolgen kann, unabhängig davon, ob eine oder mehrere Abrollvorrichtungen hintereinander aufgestellt sind. Durch das seitliche Zuführen der Vorratsrollen können diese gleichzeitig eingefahren und gleichzeitig aufgenommen werden, wodurch sich erheblich geringere Totzeiten ergeben. Da im übrigen nur der jeweils der Beschickungsseite zugewandte Tragbalken schwenkbar ausgebildet, hingegen der jeweils zugeordnete andere Tragbalken nicht schwenkbar ausgebildet ist, ergibt sich auch insofern eine erheblich einfachere bauliche Ausgestaltung .According to the invention, the universal applicability of the device is achieved in that the device or a plurality of devices which follow one another directly between the uprights of the machine frame have a roll loading or removal both in and transversely to the direction of travel of the material webs, and that the or the lateral loading facing support beams of the support frame are pivoted up. With the means according to the invention, a device is obtained in which the loading can take place both in and transversely to the web running direction, regardless of whether one or more unwinding devices are set up one behind the other. By supplying the supply rolls from the side, they can be retracted and picked up at the same time, which results in significantly shorter idle times. Since, moreover, only the support beam facing the loading side is designed to be pivotable, whereas the respectively assigned other support beam is not designed to be pivotable, this also results in a considerably simpler structural design.

Die gesamte Bedienung kann vom Boden aus erfolgen, insbesondere das Bahneinführen. Da die Abrollvorrichtungen komplett über Flur aufgestellt sind entfallen naturgemäss aufwendige Fundamentarbeiten.The entire operation can be carried out from the ground, in particular the introduction of the web. Since the unwinding devices are set up completely above the floor, there is naturally no need for complex foundation work.

Von besonderem Vorteil ist, dass die Abrollvorrichtungen mit einer Vielzahl von Zusatzeinrichtungen ausgerüstet werden, können die vom einfachsten Einsatzfall bis zur vollautomatischen Rollenbeschickung, Verbindung der abgelaufenen Bahn mit der neuen Rolle, Leerhülsenentnahme und Leerhülsenabtransport reichen.It is particularly advantageous that the unwinding devices are equipped with a large number of additional devices, which can range from the simplest application to fully automatic reel loading, connection of the expired web with the new reel, empty tube removal and empty tube removal.

Der bei einer erfindungsgemässen Vorrichtung vorhandene Raum im oberen Bereich wird in geschickter Weise zur Anordnung und Abstützung des Tragrahmens ausgenutzt. So ist vorgesehen, dass die Schwenkachse des oder der verschwenkbaren Tragbalken unmittelbar oberhalb eines die Ständer miteinander verbindenden Längsträgers an dem an seiner einen Seite schwenkbar gelagerten und an seiner anderen Seite an einer Quertraverse abgestützten Tragrahmen angeordnet ist.The space in the upper area of a device according to the invention is skillfully used to arrange and support the support frame. It is provided that the pivot axis of the pivotable support beam or beams is arranged directly above a longitudinal beam connecting the uprights to one another on the support frame which is pivotally mounted on one side and supported on a crossbar on the other side.

Zweckmässigerweise sind der oder die schwenkbaren Tragbalken in der hochgeschwenkten Stellung durch eine lösbare Rastklinke gehalten.Advantageously, the pivotable support beam or beams are held in the raised position by a releasable latch.

Die Materialbahn 13 führt hinter der Speichereinrichtung zu einer nicht dargestellten Verarbeitungsmaschine, z.B. einem Querschneider. Es können ohne weiteres mehrere der in Fig. 1 dargestellten Abrollungen hintereinander vorgesehen sein, so dass aus jeder Abrollung heraus eine Materialbahn zu der Bearbeitungsmaschine führt.1 shows a device for carrying out the method according to the invention. A longitudinal member 2 is fastened to a stand 1 set up above the floor, on which a bearing 3 is arranged for the transversely displaceable mounting of a support frame 6 supported on rollers 4 on a crossbar 5. On the support frame 6, support beams 7 are arranged on opposite sides, one of which can be pivoted about a horizontal axis 20 for the lateral insertion of a winding roller 11 via the adjustment range indicated by dash-dotted lines. The winding roll 11 is rotatably mounted on the support beam 7 via piston rods 8 and clamping heads 9 by means of clamping sleeves. The material web 13 running therefrom is guided between a transfer member designed as a circumferentially drivable suction roller 14 and a guide roller 15 to a storage roller 16 of a storage device. The storage roller 16 can be moved in the indicated arrow directions 18 by drive means, not shown. A clamping device 19 is arranged on the longitudinal beams 2. The suction roller 14 is rotatably mounted on a swivel arm 22 which can be swiveled via a cylinder piston unit 23, which is only indicated. A cutting device 27 is provided for severing the material web 13. The material web 13 leads behind the storage device to a processing machine, not shown, e.g. a cross cutter. Several of the unrollings shown in FIG. 1 can easily be provided one behind the other, so that a material web leads out of each unwinding to the processing machine.

Die Wirkungsweise der Vorrichtung ist wie folgt: Ausgehend von der in Fig. 2 dargestellten Ausgangsposition läuft die Materialbahn 13 von einer vollen Wickelrolle 11 ab und zwar entlang der Führungsrolle 15 und der Speicherwalze 16. Der Schwenkarm 22 ist nach oben geschwenkt, so dass die Saugwalze 14 mit der ablaufenden Materialbahn 13 nicht in Berührung steht. Kurz vor Ende der aufgewickelten Materialbahn 13 wird die Klemmvorrichtung 19 wirksam so wie in Fig. 3 angegeben.The mode of operation of the device is as follows: starting from the starting position shown in FIG. 2, the material web 13 runs from a full winding roller 11, specifically along the guide roller 15 and the storage roller 16. The swivel arm 22 is pivoted upward, so that the suction roller 14 is not in contact with the running material web 13. Shortly before the end of the wound material web 13, the clamping device 19 becomes effective as indicated in FIG. 3.

Darauf hin wird, wie in Fig. 4 dargestellt, die Speicherwalze 16 in der angegebenen Pfeilrichtung 31 nach links verstellt, während die Saugwalze 14 in ihrer Stellung verbleibt. Dadurch wird zwischen der Saugwalze 14 und der Speicherwalze 16 eine verlängerte «Fahne» für den weiter unten näher erläuterten Anklebevorgang erzeugt.Thereupon, as shown in FIG. 4, the storage roller 16 is adjusted to the left in the indicated arrow direction 31, while the suction roller 14 remains in its position. As a result, an elongated “flag” is generated between the suction roller 14 and the storage roller 16 for the gluing process explained in more detail below.

Wie aus Fig. 5 hervorgeht, wird im nächsten Arbeitsschritt die Materialbahn 13 durch die Schneideinrichtung 27 durchtrennt, so dass bei stillstehendem Querschneider der Restwickel entnommen werden kann.As can be seen from FIG. 5, in the next work step the material web 13 is cut device 27 is cut so that the remaining roll can be removed when the cross cutter is at a standstill.

Nunmehr wird im nächsten Schritt, wie in Fig. 6 dargestellt, durch die in Pfeilrichtung 31 umlaufend angetriebene Saugwalze 14 der vorher verlängerte Teil der Materialbahn aufgewickelt, und dabei gleichzeitig die Speicherwalze 16 in ihre ursprüngliche Ausgangsposition zurückgefahren.Now, in the next step, as shown in FIG. 6, the previously extended part of the material web is wound up by the suction roller 14 which is driven in the direction of the arrow 31, and at the same time the storage roller 16 is moved back into its original starting position.

Im nächsten Schritt wird dann gemäss Fig. 7 die Saugwalze 14 über den Schwenkarm 22 in der angegebenen Pfeilrichtung 32 nach unten bewegt und zwar so weit, bis die Saugwalze 14 am Aussenumfang einer inzwischen neu eingelegten Ersatzwickelrolle 33 zur Anlage kommt. Die Stellung des mit einem Klebestreifen 34 versehenen Anfangs der zweiten Materialbahn 35 und die Länge des zwischengespeicherten Bahnabschnittes der ersten Materialbahn 13 sind so aufeinander abgestimmt, dass der Anfang der zweiten Materialbahn und das Ende der ersten Materialbahn 13 zusammenfallen. Durch das Zusammenwirken der druckbeaufschlagten Saugwalze 14 und des Umfangs der Ersatzwickelrolle 33 lässt sich eine feste Verbindung zwischen den beiden Materialbahnen erzielen.In the next step, as shown in FIG. 7, the suction roller 14 is then moved downward in the indicated arrow direction 32 via the swivel arm 22 until the suction roller 14 comes to rest on the outer circumference of a newly inserted replacement winding roller 33. The position of the beginning of the second material web 35 provided with an adhesive strip 34 and the length of the temporarily stored web section of the first material web 13 are matched to one another such that the beginning of the second material web and the end of the first material web 13 coincide. Through the interaction of the pressurized suction roller 14 and the circumference of the replacement winding roller 33, a firm connection between the two material webs can be achieved.

In Fig. 7 ist mit strichpunktierten Linien angedeutet, dass auf die gleiche Weise auch Ersatzwickelrollen 36 mit gegenüber der Ersatzwickelrolle 33 wesentlich geringerem Durchmesser behandelt werden können, einfach dadurch, dass der Schwenkarm 22 weiter nach unten durchschwenkt. Dabei versteht es sich, dass entsprechend der festgelegten Position des Klebestreifens 34 und des jeweiligen Durchmessers der neuen Ersatzwickelrolle ein entsprechend langes Stück der ersten Materialbahn 13 über die Saugwalze 14 zwischengespeichert wird.In Fig. 7 it is indicated with dash-dotted lines that in the same way replacement winding rollers 36 with a diameter that is substantially smaller than that of the replacement winding roller 33 can be treated, simply by the fact that the swivel arm 22 swings further downward. It goes without saying that a correspondingly long piece of the first material web 13 is temporarily stored via the suction roller 14 in accordance with the fixed position of the adhesive strip 34 and the respective diameter of the new replacement winding roll.

In Fig. 8 ist schliesslich dargestellt, wie der Anfang der zweiten Materialbahn 35 nach dem Lösen der Klemmvorrichtung 19 und dem Anlaufen der Bearbeitungsmaschine über den Klebestreifen 34 mit dem Ende der ersten Materialbahn 13 verbunden ist und die neue Materialbahn in der in Fig. 2 dargestellten Weise zur Bearbeitungsmaschine läuft. Da die Beschleunigung der Ersatzwickelrolle nur durch Friktion mit der Materialbahn 13 aus dem Stillstand heraus erfolgt, sind keinerlei Antriebs- und Synchronisiereinrichtungen für die Ersatzrolle erforderlich.Finally, FIG. 8 shows how the beginning of the second material web 35, after releasing the clamping device 19 and starting up the processing machine, is connected to the end of the first material web 13 via the adhesive strip 34, and how the new material web is shown in FIG. 2 Way to the processing machine is running. Since the acceleration of the replacement winding roll is achieved only from standstill by friction with the material web 13, no drive and synchronization devices are required for the replacement roll.

Nach erfolgtem Ankleben wird schliesslich der Schwenkarm 22 gemäss Fig. 9 um die Gelenkstelle 21 nach oben geschwenkt, so dass wieder die in Fig. 2 dargestellte Ausgangsposition eingenommen ist.After the adhesive has been glued, the swivel arm 22 is finally pivoted upward about the articulation point 21 according to FIG. 9, so that the starting position shown in FIG. 2 is again assumed.

In Fig. 10 ist eine abgewandelte Abrollvorrichtung dargestellt, die, genau genommen, aus drei hintereinanderliegenden Abrollvorrichtungen besteht. An Ständern 1 eines im einzelnen nicht dargestellten Maschinengestells ist ein Längsträger 2 befestigt, auf dem ein Lager 3 für die querverschiebliche Lagerung eines über Rollen 4 an einer Quertraverse 5 abgestützten Tragrahmens 6 angeordnet ist. An dem Tragrahmen 6 sind an gegenüberliegenden Seiten Tragbalken 7 angeordnet, von denen einer zum seitlichen Einführen einer Wickelrolle 11 über den strichpunktiert angedeuteten Verstellbereich um eine horizontale Schwenkachse 20 verschwenkbar ist. An den freien Enden der Tragbalken 7 ist über Stangen 8 und Spannköpfe 9 mittels Spannhülsen eine Vorratsrolle 11 drehbar gelagert. Die davon ablaufende Materialbahn ist mit 13 bezeichnet. Die Materialbahn 13 führt zu einer nicht dargestellten Verarbeitungsmaschine, z.B. einem Querschneider. Der Tragrahmen 6 kann auf der querverlaufenden Tragachse durch Verstellmittel, beispielsweise Ritzel und Zahnstange, über Verstellmotoren quer zur Bahnlaufrichtung verstellt werden, um eine Anpassung an unterschiedlich breite Materialbahnen vornehmen zu können. Zum Halten des Tragbalkens 7 in seiner verschwenkten Stellung ist eine lösbare Rastklinke 37 vorgesehen.FIG. 10 shows a modified unrolling device which, strictly speaking, consists of three unrolling devices one behind the other. On stands 1 of a machine frame, not shown in detail, a longitudinal beam 2 is fastened, on which a bearing 3 is arranged for the transversely displaceable mounting of a supporting frame 6 supported on rollers 4 on a crossbar 5. On the support frame 6, support beams 7 are arranged on opposite sides, one of which can be pivoted about a horizontal pivot axis 20 for the lateral insertion of a winding roller 11 via the adjustment range indicated by dash-dotted lines. At the free ends of the support beams 7, a supply roll 11 is rotatably mounted on rods 8 and clamping heads 9 by means of clamping sleeves. The material web running away from this is designated by 13. The material web 13 leads to a processing machine, not shown, e.g. a cross cutter. The supporting frame 6 can be adjusted on the transverse supporting axis by adjusting means, for example pinion and rack, via adjusting motors transverse to the web running direction in order to be able to adapt to material webs of different widths. A detachable latch 37 is provided to hold the support beam 7 in its pivoted position.

Zum Wechseln der Vorratsrollen wird folgendermassen vorgegangen:The procedure for changing the supply rolls is as follows:

Der Tragrahmen 6 wird so geschwenkt, dass die Tragbalken 7 senkrecht stehen, wobei die Tragbalken 7 nach unten ausgefahren werden, bis die abgelaufene Vorratsrolle auf einem dort vorgesehenen Förderer zu liegen kommt. Nach dem Ablegen und Entfernen der leeren Vorratsrolle werden die Tragbalken wieder eingefahren und in die gestrichelt dargestellte Stellung verschwenkt. In dieser Position wird von der Seite her eine neue Vorratsrolle zugeführt und danach werden die Tragbalken zurückgeschwenkt, d.h. in die senkrechte Stellung, und dann bis auf die entsprechende und notwendige Höhe gebracht, damit die dort vorhandenen Spannköpfe beiderseits in den Achshülsen der neuen Vorratsrolle eingesetzt und befestigt werden können. Danach wird durch Betätigen der Hubeinrichtung die neue Vorratsrolle angehoben, bis sie die vorgegebene Endposition erreicht hat. Schliesslich wird die neue Vorratsrolle für das Spleissen vorbereitet und in bekannter Weise mit dem Ende der vorher abgewickelten Materialbahn verbunden.The support frame 6 is pivoted so that the support beams 7 are vertical, the support beams 7 being extended downwards until the expired supply roll comes to rest on a conveyor provided there. After placing and removing the empty supply roll, the supporting beams are retracted and pivoted into the position shown in dashed lines. In this position, a new supply roll is fed in from the side and the supporting beams are then swiveled back, i.e. in the vertical position, and then brought up to the appropriate and necessary height so that the clamping heads present there can be inserted and fastened on both sides in the axle sleeves of the new supply roll. Then the new supply roll is raised by actuating the lifting device until it has reached the predetermined end position. Finally, the new supply roll is prepared for the splicing and connected in a known manner to the end of the previously unwound material web.
