VORRICHTUNG ZUM ANLEGEN EINER WARENBAHN AN EINER WICKELHULSE DEVICE FOR CREATING A TRACK OF PRODUCTS ON A WRAPPING SLEEVE
Vorrichtung zum Anlegen von Warenbahnen, insbesondere hochempfindliche Kunst¬ stoffolien, in einer Wickelmaschine, vorzugsweise einer MehrfachwickelmaschineDevice for applying material webs, in particular highly sensitive plastic films, in a winding machine, preferably a multiple winding machine
Technisches GebietTechnical field
Die Erfindung bezieht sich auf eine Vorrichtung zum Anlegen von Warenbahnen, insbesondere hochempfindliche Kunststoffolien, in einer Wickelmaschine, vorzugs¬ weise einer Mehrfachwickelmaschine, mit in die jeweilige Wickelstellung verschwenk¬ barer Wickelwelle zur Aufnahme von Wickelhülsen, einer damit zusammenwirkenden Kontaktwalze sowie einem Quertrennsystem zum Quertrennen der Warenbahn und einem Anlegesystem zum Umlenken und Anlegen der zulaufenden Warenbahn im Bereich der Wickelhülsen.The invention relates to a device for applying webs, in particular highly sensitive plastic films, in a winding machine, preferably a multiple winding machine, with a winding shaft that can be pivoted into the respective winding position for receiving winding sleeves, a contact roller interacting therewith, and a cross-cutting system for cross-cutting the Material web and an application system for deflecting and applying the incoming material web in the area of the winding cores.
Stand der TechnikState of the art
Zum sicheren Anlegen eines neuen Bahnanfangs der Warenbahn an eine leere Wickelhülse ist es in der Praxis üblich, auf die leere Wickelhülse einen Klebestreifen oder Leim aufzubringen. Dies erfordert jedoch einmal einen besonderen Arbeitsgang und ferner werden besonders bei dünnem, hochempfindlichem Wickelgut in Folge Durchschiagens des Klebstoffs mehrere Lagen des Wickelguts unbrauchbar. Derart unbrauchbar gewordene Wickelhülsen lassen sich demzufolge auch sehr schlecht wiederaufbereiten, weil die unterschiedlichen Materialien, wie Pappe, Klebstoff und gegebenenfalls Kunststoffolie mit relativ hohem Aufwand voneinander getrennt werden müssen. Die vorliegende Erfindung geht von der Erkenntnis aus, beim Anlegen eines neuen Bahnanfangs einer aufzuwickelnden Materialbahn ganz auf einen Kleber bzw. Klebstoff zu verzichten.In order to securely place a new start of the web on an empty winding tube, it is customary in practice to apply an adhesive strip or glue to the empty winding tube. However, this requires a special operation, and furthermore, particularly in the case of thin, highly sensitive winding material, several layers of the winding material become unusable as a result of the adhesive being peeled through. Winding cores that have become unusable in this way are therefore also very difficult to reprocess because the different materials, such as cardboard, adhesive and possibly plastic film, have to be separated from one another with relatively great effort. The present invention is based on the finding that, when creating a new web start of a material web to be wound up, there is no need for an adhesive.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art zu schaffen, mittels der der Bahnanfang einer stillstehenden, quer zur Zuführrichtung durchtrennten Warenbahn, vorzugsweise hochempfindliche Kunst¬ stoffolie, ohne Stau und ohne Umschlagfalte an eine leere Wickelhülse ohne Ver¬ wendung von Klebstoff sicher angelegt wird.The invention is therefore based on the object of providing a device of the type mentioned at the beginning, by means of which the beginning of the web of a stationary web of material, preferably cut through transversely to the feed direction, preferably highly sensitive plastic film, without jam and without a fold over against an empty winding tube without using Glue is applied securely.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Anlagesystem ein um die Längsachse der Wickelwelle konzentrisch verschwenkbares, den Warenbahn¬ anfang an die Wickelhülsen andrückbares Anlegeelement aufweist. Mit den Mitteln nach der Erfindung wird auch bei sehr empfindlichen Warenbahnen, wie beispiels¬ weise hochempfindliche Kunststoffolien für die Fotoindustrie ohne Verwendung von Klebstoff ein sicheres und einwandfreies Anlegen des Warenbahnanfangs an die Wickelhülse gewährleistet.This object is achieved according to the invention in that the installation system has an application element which can be pivoted concentrically about the longitudinal axis of the winding shaft and which can be pressed onto the winding tube at the beginning of the web. With the means according to the invention, even with very sensitive webs, such as, for example, highly sensitive plastic films for the photographic industry, a secure and flawless application of the beginning of the web to the winding tube is ensured without the use of adhesive.
Dazu trägt bei, daß das Anlageelement eine konzentrisch um die Achse der Wickel¬ welle verschwenkbare, sich über die Arbeitsbreite der Maschine erstreckende Verbin¬ dungsstange und daran befestigte, federnd ausgebildete Andrückelemente aufweist, an deren freien Enden vorzugsweise Rollen oder dergleichen drehbar gelagert sind. Die beispielsweise als Zungen oder als federnde Haltebleche ausgebildeten Andrück¬ elemente sind als Tragelemente für die mehr oder weniger dicht an dicht stehenden Andrückrollen oder dergleichen ausgebildet. Mittels einer derartigen Ausgestaltung der Andrückelemente kommt man zu einem vollkommen formatunabhängigen Anlegesystem, da die Andrückrollen so dicht nebeneinander stehen, daß bei einer erforderlichen Schnittbreitenänderung keine Anpassung des Anlegesystems erforder¬ lich ist. Von Bedeutung für die Erfindung ist ferner, daß an den Enden der Verbindungsstange jeweils ein Verschwenkmechanismus angeordnet ist. Der zur Zentrierung und Führung dienende Verschwenkmechanismus weist eine über einen Hebel mit der Verbindungsstange verbundene aufgeschlitzte erste Ringscheibe und eine dazu konzentrisch angeordnete, gegenüber der ersten Ringscheibe relativ verschwenkbare, aufgeschlitzte zweite Ringscheibe auf, deren gemeinsamer gedachter Mittelpunkt in ' der Anlegestellung des Anlegesystems mit der Längsachse der Wickelwelle zusam¬ menfällt.This is due to the fact that the contact element has a connecting rod which can be pivoted concentrically about the axis of the winding shaft and extends over the working width of the machine, and has spring-mounted pressure elements fastened thereon, on the free ends of which rollers or the like are preferably rotatably mounted. The pressure elements, which are designed, for example, as tongues or as resilient holding plates, are designed as support elements for the pressure rollers or the like that are more or less close to one another. Such a design of the pressing elements leads to a completely format-independent application system, since the pressure rollers are so close together that no adjustment of the application system is necessary if the required cutting width is changed. It is also important for the invention that a pivoting mechanism is arranged at the ends of the connecting rod. The pivoting mechanism used for centering and guiding has a slotted first ring disk connected to the connecting rod via a lever and a slotted second ring disk concentrically arranged and slotted relative to the first ring disk, the common imaginary center of which in the application position of the application system with the longitudinal axis the winding shaft coincides.
Zum Antrieb der verschwenkbaren Ringscheibe des Verschwenkmechanismus sind wenigstens zwei in eine Verzahnung am Umfang der verdrehbaren Ringscheibe eingreifende, mit Abstand zueinander angeordnete Zahnräder vorgesehen, von denen während der Verschwenkbewegung zumindest eines immer im Eingriff mit der Ver- zahnung der drehbaren Ringscheibe steht. Dadurch wird sichergestellt, daß in dem Fall, wenn das eine Zahnrad im Bereich des in der drehbaren Scheibe vorgesehenen Schlitzes außer Antriebseingriff gelangt, daß andere Zahnrad noch mit der Ver¬ zahnung im Antriebseingriff steht, so daß ein ständiges ununterbrochenes Ver¬ schwenken des Anlegesystems garantiert wird.To drive the swiveling ring disk of the swiveling mechanism, at least two toothed wheels which engage in a toothing on the circumference of the rotatable ring disk and are arranged at a distance from one another are provided, of which at least one is always in engagement with the toothing of the rotatable ring disk during the swiveling movement. This ensures that when one gear in the area of the slot provided in the rotatable disc is out of drive engagement, the other gear is still in engagement with the toothing, so that a constant, uninterrupted pivoting of the contact system is guaranteed becomes.
Im übrigen ist vorteilhafterweise das Anlegesystem derart ausgebildet, daß bei dem kurz vor dem Quertrennen der Warenbahn erfolgenden Einschwenken des Anlegesy¬ stems mittels der Andrückelemente bzw. der Andrückrollen die Warenbahn unter leichter Vorspannung an die Wickelhülse angedrückt wird. Ferner entspricht die nach dem Quertrennen der Warenbahn verbleibende Materialstrecke zwischen den An¬ drückrollen in ihrer anfänglichen Anlegestellung und einem Schneidmesser des Quertrennsystems im wesentlichen dem restlichen Umfang der Wickelhülse zwischen der anfänglichen Berührungsstelle der Andrückrollen an der Wickelhülse und der Kontaktstelle zwischen der Kontaktwalze und der Wickelhülse.For the rest, the application system is advantageously designed such that when the application system is swiveled in shortly before the crosswise separation of the web by means of the pressure elements or the pressure rollers, the web is pressed onto the winding tube with slight pretension. Furthermore, the length of material remaining after the cross cutting of the web between the pressure rollers in their initial contact position and a cutting knife of the cross cutting system essentially corresponds to the remaining circumference of the winding tube between the initial contact point of the pressure rollers on the winding tube and the contact point between the contact roller and the winding tube.
Schließlich ist die Schwenkbewegung des Anlegesystems derart begrenzt, daß die Andrückrollen unmittelbar vor der Kontaktstelle zwischen der Kontaktwalze und der Wickelhülse zum Stehen kommen. Das erfindungsgemäß ausgebildete Anlegesystem läßt sich auch sehr leicht auf unterschiedliche Hülsendurchmesser anpassen. Zu diesem Zweck braucht die Verbindungsstange lediglich um ihre eigene Achse verschwenkt werden. Damit verändern die über die federnden Zungen oder Haltebleche befestigten Andrückrollen ihren Radius bezogen auf die imaginäre Rotationsachse.Finally, the pivoting movement of the application system is limited in such a way that the pressure rollers come to a stop immediately in front of the contact point between the contact roller and the winding tube. The application system designed according to the invention can also be very easily adapted to different sleeve diameters. For this purpose, the connecting rod only needs to be pivoted about its own axis. The pressure rollers attached via the resilient tongues or holding plates thus change their radius in relation to the imaginary axis of rotation.

Weg zur Ausführung der ErfindungWay of carrying out the invention
In den Figuren 1 bis 6 ist in schematischer Seitenansicht eine Zweifachwickelma¬ schine mit den Vorrichtungen zum Quertrennen und Anlegen der Warenbahn 1 , beispielsweise einer hochempfindlichen Kunststoffolie dargestellt. Die Warenbahn 1 ist um eine Umlenkrolle 2 und eine Kontaktwalze 3 herumgeführt, wonach in bekannter Weise die Warenbahn auf eine Wickelrolle 4 aufgewickelt wird. Diametral gegenüberliegend der Wickelrolle 4 läßt sich während des Wickelvorgangs eine sich über die Maschinenbreite erstreckende Wickelwelle 10 mit Wickelhülsen 5 bestücken. Die Wickelwelle kann in weiter unten näher beschriebener Weise durch Verdrehen eines Wendekreuzes der Zweifachwickelmaschine in die Stellung der jetzigen Wickelrolle 4 verschwenkt werden. Zur Zweifachwickelmaschine gehört in dem hier interessierenden Umfang ferner ein Anlegesystem 6 sowie ein Quertrennsystem 7 für die Warenbahn. Das Quertrennsystem 7 weist zwei zangenartig aufeinander zu bzw. auseinanderbewegbare Traghebel 8 auf, an deren freien Enden Schneidmesser 9 sitzen. Beide Traghebel sind um eine gemeinsame Schwenkachse 1 1 verschwenkbar. Im dargestellten Ausführungsbeispiel ist um diese Schwenkachse 1 1 auch ein Tragarm 1 2 des Anlegesystems 6 verschwenkbar. Am bzw. nahe dem freien Ende weist der Tragarm 1 2 ein Anlegeelement 13 und einen Verschwenkmechanismus 14 auf, die beide weiter unten näher erläutert werden.FIGS. 1 to 6 show a schematic side view of a double-winding machine with the devices for cross-cutting and applying the web 1, for example a highly sensitive plastic film. The material web 1 is guided around a deflection roller 2 and a contact roller 3, after which the material web is wound onto a winding roller 4 in a known manner. Diametrically opposite the winding roll 4, a winding shaft 10 extending over the machine width can be equipped with winding sleeves 5 during the winding process. The winding shaft can be pivoted in the manner described in more detail below by rotating a turning cross of the double winding machine into the position of the current winding roller 4. To the extent of interest here, the double winding machine also includes a lay-on system 6 and a cross-cutting system 7 for the web. The cross-cutting system 7 has two supporting levers 8, which can be moved towards and away from one another like pliers, with cutting knives 9 sitting at their free ends. Both support levers can be pivoted about a common pivot axis 1 1. In the illustrated embodiment, a support arm 1 2 of the positioning system 6 can also be pivoted about this pivot axis 1 1. At or near the free end, the support arm 1 2 has an application element 13 and a pivoting mechanism 14, both of which are explained in more detail below.
Ein bevorzugtes Ausführungsbeispiel eines Anlegeelementes 13 sowie eines Ver- Schwenkmechanismus 14 ist in den Figuren 7 und 8 dargestellt. Das Anlegeelement 13 weist eine konzentrisch um die Achse 1 5 der Wickelwelle 10 verschwenkbareA preferred embodiment of an application element 13 and a pivoting mechanism 14 is shown in FIGS. 7 and 8. The contact element 13 has a pivotable concentrically about the axis 15 of the winding shaft 10
Verbindungsstange 16 auf, die sich über die Arbeitsbreite der Wickelmaschine erstreckt und an der federnd ausgebildete Andrückelemente 17 in Form von federn¬ den Halteblechen bzw. Zungen frei abstehend befestigt sind. An den vorderen Enden der Zungen 17 sind Andrückrollen 18 drehbar gelagert, die in weiter unten näher beschriebener Weise mit der Warenbahn zur Anlage gelangen und das Anlegen eines neuen Warenbahnanfangs um die Wickelhülse 5 bewirken.Connecting rod 16, which extends over the working width of the winding machine and on which resiliently formed pressing elements 17 in the form of springy holding plates or tongues are fastened in a freely projecting manner. At the front ends of the tongues 17 pressure rollers 18 are rotatably mounted, which come into contact with the web in the manner described in more detail below and cause the creation of a new web start around the winding tube 5.
An jedem Ende der Verbindungsstange 16 ist der oben bereits erwähnte Ver¬ schwenkmechanismus 14 angeordnet. Dieser Verschwenkmechanismus besteht im einzelnen aus zwei, jeweils mit einem Schlitz 20 versehenen, im wesentlichen C- förmig ausgebildeten Ringscheiben 1 9, 21 , von denen die zuerst genannte Ring¬ scheibe 19 über einen Hebel 22 mit der Verbindungsstange 16 verbunden ist, während die andere Ringscheibe 21 an dem Tragarm 1 2 des Anlegesystems befestigt ist. Die Ringscheibe 19 ist gegenüber der fest am Tragarm 1 2 angeordneten Ring¬ scheibe 21 relativ verdrehbar. Zu diesem Zweck ist die Ringscheibe 1 9 an einem Zwischenring 23 befestigt, der an seiner Außenseite 24 eine Verzahnung aufweist und der mit zwei Zahnrädern 25, 26 im Verzahnungseingriff steht. Die Zahnräder 25, 26 sitzen jeweils auf einem Achsstummel 27, der über Wälzlager 28 in einer Bohrung 29 des Traghebels 12 drehbar gelagert ist. Entsprechend den Zahnrädern 25, 26 sitzen auf der gegenüberliegenden Seite des Tragarms 2 auf dem Achsstummel 27 Antriebszahnräder 31 , über welche sowie nicht dargestellte Zahnriemen oder der¬ gleichen und eine gleichfalls nicht dargestellte Verbindungswelle ein synchroner Antrieb der beiden verdrehbaren Ringscheiben 19 gewährleistet wird. Der Abstand der Zahnräder 25, 26 zueinander ist derart gewählt, daß der Verschwenkantrieb der Ringscheibe 19 durch eines der Zahnräder 25 bzw. 26 auch dann aufrechterhalten wird, wenn das andere Zahnrad in den Bereich des Schlitzes 20 der Ringscheibe gelangt.The pivoting mechanism 14 already mentioned above is arranged at each end of the connecting rod 16. This pivoting mechanism consists in particular of two ring disks 19, 21, each provided with a slot 20, of essentially C-shaped design, of which the first-mentioned ring disk 19 is connected to the connecting rod 16 via a lever 22, while the other Washer 21 is attached to the support arm 1 2 of the application system. The annular disk 19 is relatively rotatable relative to the annular disk 21 which is fixedly arranged on the support arm 12. For this purpose, the annular disc 19 is fastened to an intermediate ring 23 which has teeth on its outside 24 and which is in meshing engagement with two gears 25, 26. The gear wheels 25, 26 are each seated on an axle stub 27 which is rotatably mounted in a bore 29 of the carrying lever 12 via roller bearings 28. Corresponding to the gear wheels 25, 26, on the opposite side of the support arm 2, on the axle stub 27, drive gear wheels 31, via which toothed belts or the like (not shown) or the like and a connecting shaft (also not shown) ensure synchronous drive of the two rotatable ring disks 19. The distance between the gear wheels 25, 26 is chosen such that the pivoting drive of the ring disk 19 is maintained by one of the gear wheels 25 and 26 even when the other gear wheel comes into the area of the slot 20 of the ring disk.
Die erfindungsgemäß ausgebildete Vorrichtung zum Quertrennen und Anlegen einer Warenbahn erfolgt in der folgenden Weise:The device designed according to the invention for cross-cutting and applying a material web takes place in the following way:
Ausgehend von der in Fig. 1 dargestellten Anordnung wird, sobald die Wickelrolle 4 ihren gewünschten Umfang erreicht hat, diese in die in Fig. 2 gezeigte Lage ver¬ schwenkt. Bei dieser Bewegung gelangt die vorher vorbereitete Wickelwelle 10 mit den darauf sitzenden Wickelhülsen 5 in die gleichfalls in Fig. 2 gezeigte Stellung. Die Warenbahn 1 erstreckt sich somit von den Wickelhülsen 5 bis zur Wickelrolle 4. Vorher ist die Kontaktwalze 3 über ihren Schwenkarm 3' bis auf die Wickelhülsen 5 verschwenkt worden, so daß zwischen diesen die Warenbahn einwandfrei geführt und eingeklemmt wird. Wie aus Fig. 3 ersichtlich, wird nun der gestrichelt dargestell- te Tragarm 1 2 soweit nach oben verschwenkt, daß die Schwenkmechanismen 14 die Wickelwelle 10 von unten her umgreifen können, und zwar außerhalb der eigentli¬ chen Arbeitsbreite, so daß die Warenbahn nach wie vor von den auf der Wickelachse sitzenden Wickelhülsen zu der Wickelrolle 4 verläuft. In dieser Stellung liegen die Andrückrollen 18 unter leichten Druck an der um die Wickelhülse 5 herumgeführten Warenbahn an, so wie das deutlicher in Fig. 9 gezeigt ist. Entsprechend Fig. 4 werden nun die Traghebel 8 des Quertrennsystems 7 zangen¬ artig aufeinander zubewegt, so daß durch die daran sitzenden Schneidmesser 9 die Warenbahn durchtrennt wird. Der Abstand zwischen den Andrückrollen 18 bis zu den Schneidmessern 9 entspricht in etwa dem Restumfang von der anfänglichen Berüh- rungsstelle der Andrückrollen 18 an der Wickelhülse bis zu der Kontaktstelle zwi¬ schen der Kontaktwalze 3 und der Wickelhülse 5. Nach dem Durchtrennen der Warenbahn wird durch den oben beschriebenen Verschwenkmechanismus 14 über die drehbare Ringscheibe 19 sowie den Hebel 22 die Verbindungsstange 16 auf einem konzentrischen Kreis 20 bewegt, so wie das aus Fig. 9 ersichtlich ist und zwar solange und so weit, bis die Andrückrollen 18 kurz vor Erreichen der Kontaktstelle zwischen der Andrückwalze 3 und der Wickelhülse 5 zum Stehen kommen. Durch diese Schwenkbewegung der Verbindungsstange 16 und der Andrückelemente wird der Warenbahnanfang einwandfrei und ohne Falten sowie ohne Verwendung von Klebstoff sicher um die Wickelhülse 5 herumgelegt. Die Endstellung der Verbin- dungsstange 16 und der daran befestigten Andrückrollen 18 ist in Fig. 10 mit ausgezogenen Linien dargestellt. Nach dem Anwickeln von einigen Windungen der Warenbahn wird über den Verschwenkmechanismus 14 die Ringscheibe 19 so verdreht, daß der Verschwenkmechanismus von der Wickelwelle wieder frei kommt, so daß dann über den Tragarm 1 2 der-Anlegemechanismus wieder in seine in Fig. 6 bzw. 1 dargestellte Ausgangslage zurückverschwenkt werden kann. Das gleiche gilt sinngemäß auch für das Quertrennsystem 7. Starting from the arrangement shown in FIG. 1, as soon as the winding roll 4 has reached its desired circumference, it is pivoted into the position shown in FIG. 2. During this movement, the previously prepared winding shaft 10 with the winding sleeves 5 sitting thereon reaches the position likewise shown in FIG. 2. The web 1 thus extends from the winding tubes 5 to the winding roll 4. Before that, the contact roller 3 has been pivoted via its swivel arm 3 'to the winding tubes 5, so that the web is guided and clamped properly between them. As can be seen from FIG. 3, the support arm 1 2 shown in dashed lines is now pivoted upwards to such an extent that the pivoting mechanisms 14 can grip around the winding shaft 10 from below, specifically outside the actual working width, so that the material web is still runs from the winding sleeves sitting on the winding axis to the winding roll 4. In this position, the pressure rollers 18 bear under slight pressure on the web of material guided around the winding tube 5, as is shown more clearly in FIG. 9. According to FIG. 4, the carrying levers 8 of the cross-cutting system 7 are now moved towards one another in the manner of pliers, so that the web of material is cut through by the cutting knives 9 seated thereon. The distance between the pressure rollers 18 to the cutting knives 9 corresponds approximately to the remaining circumference from the initial contact point of the pressure rollers 18 on the winding tube to the contact point between the contact roller 3 and the winding tube 5. After the material web has been cut through, the pivoting mechanism 14 described above, via the rotatable annular disk 19 and the lever 22, moves the connecting rod 16 on a concentric circle 20, as can be seen in FIG. 9 and until the pressure rollers 18 shortly before reaching the contact point between the pressure roller 3 and the winding tube 5 come to a stop. This pivoting movement of the connecting rod 16 and the pressing elements ensures that the beginning of the web is securely wrapped around the winding tube 5 without folds and without the use of adhesive. The end position of the connecting rod 16 and the pressure rollers 18 fastened thereon is shown in solid lines in FIG. 10. After the winding of a few turns of the material web, the washer 19 is rotated via the pivoting mechanism 14 in such a way that the pivoting mechanism is released from the winding shaft again, so that the support mechanism 1 2 then brings the contact mechanism back into its position in FIGS. 6 and 1 respectively shown starting position can be pivoted back. The same applies analogously to the cross-cutting system 7.
