Description
Die Erfindung betrifft eine Vorrichtung zum Aufwickeln einer Materialbahn gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a device for winding a material web according to the preamble of claim 1.
Vorrichtungen zum Aufwickeln werden beispielsweise, jedoch keineswegs ausschließlich, beim Auspacken von Materialrollen verwendet, um die auf der Rolle aufgespulte Materialbahn, beispielsweise eine Papierbahn, anschließend in einer Rollenrotationsdruckmaschine bedrucken zu können. Aufgabe der Vorrichtung ist es dabei insbesondere, die äußersten Schichten der Materialrolle, die sogenannte Makulatur, unter Bildung eines Wickelkörpers aufzuwickeln und dadurch zu entfernen. Daneben ist es auch denkbar, die Umfangsverpackung von der Materialrolle mit Vorrichtungen aufzuwickeln und dadurch zu entfernen.Winding devices are used, for example, but by no means exclusively, in unpacking rolls of material in order to be able to print on the roll of material wound on the roll, for example a paper web, subsequently in a web-fed rotary printing press. The object of the device is, in particular, to wind up the outermost layers of the material roll, the so-called wastepaper, to form a wound body and thereby to remove it. In addition, it is also conceivable to wind the peripheral packaging of the roll of material with devices and thereby remove.
Um die Materialbahn auf dem Wickelkörper aufspulen zu können, muss der Bahnanfang der Materialbahn zuverlässig am Wickelkörper befestigt werden.In order to wind the material web on the winding body, the web start of the material web must be reliably secured to the winding body.
Die DE-PS 742 860 beschreibt eine Wickelvorrichtung für Gewebestreifen, bei der ein Bahnanfang zwischen zwei Halbschalen geklemmt und anschließend auf diesen aufgewickelt wird.DE-PS 742 860 describes a winding device for fabric strips, in which a web beginning between two half-shells clamped and then wound up on this.
Die US 5 533 687 A offenbart eine Vorrichtung zum Aufwickeln einer Materialbahn mit einem Wickelkörper, an dem der Bahnanfang der Materialbahn befestigbar ist. Der Wickelkörper weist zwei Klemmelemente auf, die gegeneinander verstellt werden können, wobei zwischen den beiden Klemmelementen ein Klemmspalt gebildet wird, in den der Bahnanfang einführbar und befestigbar ist.No. 5,533,687 A discloses a device for winding up a material web with a winding body to which the web start of the material web can be fastened. The winding body has two clamping elements which can be adjusted against each other, wherein between the two clamping elements, a clamping gap is formed, in which the web start is inserted and fastened.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Aufwickeln einer Materialbahn zu schaffen.The invention has for its object to provide a device for winding a web.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst.The object is achieved by the features of claim 1.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, dass am Wickelköper zwei Klemmelemente vorgesehen sind, die gegeneinander verstellt werden können. Durch die Klemmelemente wird ein Klemmspalt gebildet, in den der Bahnanfang der Materialbahn einführbar ist. Durch entsprechend geeignete Verstellung zumindest eines der Klemmelemente werden diese gegeneinander gedrückt, wobei der Bahnanfang zwischen den Klemmelementen beklemmt wird. Aufgrund dieser kraftschlüssigen Fixierung des Bahnanfangs zwischen den Klemmelementen ist eine zuverlässige Befestigung der Materialbahn am Wickelkörper gegeben. Außerdem ist zuverlässig gewährleistet, dass beim rotatorischen Antrieb des Wickelkörpers die Materialbahnen eng anliegend aufgewickelt wird, so dass ein fest aufgespulter Wickel entsteht. Soll der auf den Wickelkörper aufgespulte Wickel anschließend entfernt werden, wird dazu das Klemmelement unter Öffnung des Klemmspaltes verstellt, um den Bahnanfang frei zu geben. Die aufgewickelte Materialbahn kann dann einfach seitlich vom Wickelkörper abgezogen werden.The advantages achieved by the invention are, in particular, that two winding elements are provided on the winding body, which can be adjusted against each other. By the clamping elements, a clamping gap is formed, in which the web start of the material web is inserted. By appropriately suitable adjustment of at least one of the clamping elements they are pressed against each other, wherein the web start is clamped between the clamping elements. Due to this frictional fixation of the web beginning between the clamping elements a reliable attachment of the material web is given on the winding body. In addition, it is reliably ensured that in the rotary drive of the wound body, the material webs is wound tight fitting, so that a tightly wound up winding. If the wound on the winding body winding is subsequently removed, the clamping element is adjusted under opening of the nip in order to release the web beginning. The wound material web can then be easily pulled off the side of the bobbin.
Wird die Materialbahn zur Bildung eines festen Wickels unter Spannung auf den Wickelkörper aufgespult, so folgt daraus, dass die aufgespulte Materialbahn unter Spannung am Wickelkörper anliegt und aufgrund der zwischen Wickelkörper und innerster Lage der Materialbahn wirkenden Reibungskräfte nur noch schwer bzw. gar nicht mehr vom Wickelkörper abgezogen werden kann. Dieses Problem kann dadurch gelöst werden, dass die Breite des Klemmspaltes am Außenumfang des Wickelkörpers veränderbar ist. Denn durch Öffnen des am Außenumfang des Wickelkörpers angeordneten Klemmspaltes kann der effektive Durchmesser des Wickelkörpers, der von der Materialbahn umschlungen werden muss, verändert werden. Aus der Öffnung des Klemmspaltes folgt dabei eine Verringerung des effektiven Durchmessers, so dass die auf den Wickelkörper aufgewickelte Materialbahn entspannt wird und somit leicht vom Wickelkörper abgezogen werden kann.If the web is wound under tension on the winding body to form a tight roll, it follows that the wound web travels under tension on the winding body and due to the force acting between the winding body and innermost layer of the web friction forces only hard or no longer from the winding body can be deducted. This problem can be solved in that the width of the clamping gap on the outer circumference of the winding body is variable. For by opening the arranged on the outer circumference of the winding body clamping gap, the effective diameter of the winding body, which must be wrapped by the material web, be changed. From the opening of the nip thereby follows a reduction of the effective diameter, so that the wound on the winding body material web is relaxed and thus can be easily removed from the winding body.
In welcher Art und Weise die Klemmelemente konstruktiv ausgebildet sind, ist grundsätzlich beliebig. Nach einer bevorzugten Ausführungsform der Erfindung sind die Klemmelemente in der Art von dem wesentlichen koaxial angeordneten Schalen ausgebildet, auf deren gemeinsam gebildeten Umfangsfläche die Materialbahn aufwickelbar ist. Das bedeutet mit anderen Worten, dass die Klemmelemente selbst, nämlich die Schalen, den Wickelkörper bilden. Die beiden Schalen sind dabei derart ausgebildet, dass der Klemmspalt zur Befestigung des Bahnanfangs der Materialbahn von zwei einander gegenüberliegenden Kanten der Schalen gebildet wird. Die koaxial angeordneten Schalen können gegeneinander verdreht werden, so dass sich die entsprechenden Kanten der Schalen relativ zueinander verstellen lassen, wodurch der Klemmspalt geöffnet bzw. geschlossen werden kann.In what manner the clamping elements are constructive, is basically arbitrary. According to a preferred embodiment of the invention, the clamping elements are formed in the manner of the substantially coaxially arranged shells, on the jointly formed circumferential surface of the material web is wound up. In other words, this means that the clamping elements themselves, namely the shells, form the winding body. The two shells are designed such that the clamping gap is formed for fastening the web start of the web of material from two opposite edges of the shells. The coaxially arranged shells can be rotated against each other, so that the corresponding edges of the shells can be adjusted relative to each other, whereby the clamping gap can be opened or closed.
Um die Anlagefläche an den Schalen, in denen die Reibkräfte zwischen dem Bahnanfang der Materialbahn und den Schalen übertragen werden, zu vergrößern, können an den Kanten der beiden Schalen, die den Klemmspalt bilden, Nasen angeformt sein. Diese Nasen erstrecken sich ausgehend vom Umfang des Wickelkörpers ins Innere des Wickelkörpers, so dass die Materialbahn eine großflächige Anlagefläche erhält.In order to increase the contact surface on the shells, in which the frictional forces between the web start of the web and the shells are transmitted, can be formed on the edges of the two shells, which form the nip, noses. These lugs extend from the circumference of the winding body into the interior of the winding body, so that the material web receives a large contact surface.
Um ein möglichst einfaches Einführen des Bahnanfangs im Klemmspalt zu ermöglichen, ist es besonders vorteilhaft, wenn an einer der Nasen ein Anschlag angeformt ist, an der die Vorderkante der Materialbahn beim Einführen des Bahnanfangs im Klemmspalt zur Anlage bringbar ist. Dadurch ist insbesondere auch gewährleistet, dass die Materialbahn vor Schließen des Klemmspaltes ausreichend tief in den Klemmspalt eingeführt ist, so dass sich eine ausreichend große Anlagefläche zwischen den Klemmelementen und dem Bahnanfang ergibt.In order to enable the easiest possible insertion of the web start in the nip, it is particularly advantageous if a stop is formed on one of the lugs on which the front edge of the web during insertion of the web start in the nip can be brought to bear. This ensures in particular also ensures that the material web is sufficiently deep inserted into the nip before closing the nip, so that there is a sufficiently large contact surface between the clamping elements and the web start.
In welcher Weise der Antrieb des Wickelkörpers realisiert ist, ist grundsätzlich beliebig. Nach einer bevorzugten Ausführungsform kann die eine Schale des Wickelkörpers, insbesondere die innere Schale, mit einer Antriebseinrichtung rotatorisch angetrieben werden. Durch den rotatorischen Antrieb kann einerseits der Klemmspalt geöffnet bzw. geschlossen werden und anderseits die beim Aufwickeln der Makulatur erforderliche Antriebsbewegung realisiert werden.In what way the drive of the bobbin is realized, is basically arbitrary. According to a preferred embodiment, one shell of the wound body, in particular the inner shell, can be driven in rotation by means of a drive device. On the one hand, the clamping gap can be opened by the rotary drive or be closed and on the other hand, the required when winding up the waste paper drive motion can be realized.
Die andere zweite Schale kann frei drehbar gelagert werden. In diesem Fall wird sie nur passiv von der anderen Schale mitangetrieben.The other second shell can be freely rotatably mounted. In this case, it is only passively driven by the other shell.
Nach einer bevorzugten Ausführungsform ist der Drehwiderstand der frei drehbaren Schale einstellbar. Durch Wahl eines ausreichend hohen Drehwiderstandes kann gewährleistet werden, dass die rotatorisch antreibbare Schale gegen die frei drehbar gelagerte Schale gefahren werden kann und sich dabei eine ausreichend hohe Klemmkraft im Klemmspalt zwischen den beiden Schalen ergibt.According to a preferred embodiment, the rotational resistance of the freely rotatable shell is adjustable. By choosing a sufficiently high rotational resistance can be ensured that the rotatably driven shell can be moved against the freely rotatably mounted shell and thereby results in a sufficiently high clamping force in the nip between the two shells.
Eine Einstellung des Drehwiderstandes ist insbesondere auch beim Öffnen des Klemmspaltes von Vorteil. Beim Öffnen des Klemmspaltes muss die angetriebene Schale in Gegenrichtung angetrieben werden, wobei sich die frei drehbare Schale nicht mitdrehen darf, da ansonsten der Klemmspalt geschlossen bleibt. Um ein Öffnen auch bei entsprechend hohen Spannungen der aufgewickelten Materialbahn realisieren zu können, ist es deshalb besonders vorteilhaft, wenn die frei drehbare Schale mit einer Bremseinrichtung wahlweise abgebremst bzw. festgestellt werden kann. Im Ergebnis kann dann die frei drehbar gelagerte Schale so festgelegt werden, dass die antreibbare Schale sich relativ dazu bewegen kann und dadurch der Klemmspalt geöffnet wird.An adjustment of the rotational resistance is particularly advantageous when opening the nip. When opening the clamping gap, the driven shell must be driven in the opposite direction, with the freely rotatable shell must not rotate, otherwise the nip remains closed. In order to be able to realize an opening even with correspondingly high voltages of the wound-up material web, it is therefore particularly advantageous if the freely rotatable shell can be optionally braked or fixed with a braking device. As a result, then the freely rotatably mounted shell can be set so that the drivable shell can move relative thereto and thereby the nip is opened.

Zur Vorbereitung von Materialrollen 01, auf denen eine Materialbahn, nämlich eine Papierbahn aufgespult ist, für den Druck in einer Rollenrotationsdruckmaschine, müssen die Materialrollen 01 von der für den Transport erforderlichen Umfangsverpackung befreit werden. Außerdem müssen zur Vermeidung von Störungen in der Druckmaschine die ersten Lagen der Materialrollen 01, die sogenannte Makulatur, vor Einbringung in die Druckmaschine abgespult und entfernt werden.For preparing
Das Entfernen der Umverpackung und der Makulatur wird in der in Fig. 1 dargestellten Auspackstation mit einer Vorrichtung 02 realisiert. Die Vorrichtung 02 ist in Fig. 2 vergrößert dargestellt.The removal of the outer packaging and the waste paper is realized in the unpacking station shown in FIG. 1 with a
An der Vorrichtung 02 sind zwei koaxial angeordnete Schalen 03; 04 vorgesehen, die gemeinsam den Umfang eines Wickelkörpers bilden, auf dem die Umfangsverpackung der Materialrollen 01 bzw. die Makulatur aufgespult werden kann. Beim Auspacken einer Materialrolle 01 wird die Vorrichtung 02 derart über der Materialrolle 01 angeordnet, dass eine in der Art eines Leitblechs 06 ausgebildete Leiteinrichtung 06 auf dem Umfang der Materialrolle 01 zur Anlage kommt. Mittels des Leitelements 06 kann der Bahnanfang der Materialrolle 01 zur Vorrichtung 02 geführt werden.On the
An den beiden Klemmelementen 03; 04, z. B. Schalen 03; 04 sind zwei einander gegenüberliegende Kanten 07; 08 vorgesehen, die gemeinsam einen am Umfang des Wickelkörpers angeordneten Klemmspalt 09 bilden. In diesen Klemmspalt 09 wird der Bahnanfang der Materialbahn am Leitelement 06 eingeführt. Die innere Schale 04 wird anschließend durch Antrieb mittels einer im Gehäuse 11 angeordneten Antriebseinrichtung im Uhrzeigersinn angetrieben. Zugleich wird die frei drehbar gelagerte äußere Schale 03 mittels einer im Gehäuse 11 angeordneten Bremseinrichtung unter Einhaltung eines bestimmten Drehwiderstandes derart abgebremst, dass die beiden Schalen 03; 04 gegeneinander verdreht werden. Im Ergebnis schließt sich dadurch der Klemmspalt 09, wodurch der Bahnanfang der Materialbahn zwischen den Kanten 07; 08 beklemmt wird.At the two
Zur Vergrößerung der Anlageflächen an den Kanten 07; 08 sind an beiden Kanten 07; 08 jeweils sich ins Innere des Wickelkörpers erstreckende Nasen 12 bzw. 13 angeformt. Die Nase 12 erstreckt sich dabei weiter ins Innere des von den Schalen 03; 04 gebildeten Wickelkörper, so dass an der inneren Kante der Nase 12 ein Anschlag 14 vorgesehen werden kann, an der die Vorderkante der Materialbahn beim Einführen des Bahnanfangs in den Klemmspalt 09 zur Anlage bringbar ist.To increase the contact surfaces at the
Sobald der Bahnanfang der Materialbahn zwischen den beiden Schalen 03; 04 beklemmt ist, wird die Materialbahn durch Antrieb der inneren Schale 04 und Lösen der Bremseinrichtung an der äußeren Schale 03 auf den von den Schalen 03; 04 gebildeten Wickelkörper aufgewickelt. Die Bremse ist so ausgeführt, dass sie zu jeder Zeit mit einem einstellbaren, geringen Bremsmoment die äußere Schale 03 abbremst, ansonsten wäre die Klemmkraft zu gering bei der ersten Umdrehung. Ist eine ausreichende Menge von Makulatur von der Materialrolle 01 entfernt, wird die Materialbahn von Hand durchtrennt und am Ende der Makulatur mittels der Klebeeinrichtung 16 ein Klebeband angebracht. Durch dieses Klebeband kann das Bahnende am Umfang der auf den Schalen 03; 04 aufgewickelten Materialbahn fixiert werden, so dass ein unerwünschtes Abwickeln der Materialbahn ausgeschlossen ist.Once the web start of the web between the two
Zum Abnehmen der auf die Schalen 03; 04 aufgewickelten Materialbahn wird die äußere Schale 03 durch Eingriff der im Gehäuse 11 angeordneten Bremseinrichtung festgestellt und die innere Schale 04 entgegen dem Uhrzeigersinn relativ zur äußeren Schale 03 verdreht. Dadurch öffnet sich der Klemmspalt 09 und gibt den Bahnanfang der aufgewickelten Materialbahn frei. Außerdem verkleinert sich durch Öffnen des am Umfang des Wickelkörpers angeordneten Klemmspalts 09 die effektive Umfangslänge, so dass die auf die Schalen 03; 04 aufgewickelte Materialbahn entspannt wird und einfach zur Seite abgezogen werden kann.To remove the on the

Durch horizontale Verschwenkung der Vorrichtung 02 kann diese in Richtung eines Makulaturbehälters geschwenkt werden, so dass die auf die Schalen 03; 04 aufgewickelte Makulatur nach dem Abziehen in den darunter angeordneten Makulaturbehälter fällt.As can be seen in FIG. 1, the
