  • Said web guide roller 5 may be a contact roller. With such a contact roller, the material web is brought to the winding so that a defined amount of air is wrapped between the individual layers of the coil. For this purpose, a defined distance between the web guide roll and the winding is produced.
  • a winding shaft 6 can be seen. Although it is also shown in this regard that this winding shaft 6 is mounted in the parts of the machine frame 3, 4, but this is a simplified representation. In general, the winding shaft is mounted in auxiliary racks, so that the winding shaft is movable radially and / or in the circumferential direction of the web guide roller. The movement in the circumferential direction is necessary, for example, in an automatic roll change.

  • the winding shaft 12 is held at one end in a holder 13, wherein the winding shaft 12 and holder 13 are coupled together and thus separated from each other, so that the holder 13 can each take a winding shaft with finished wound rollers from the winding device 1.
  • the holder 13 can not hold it over the winding shaft; rather, the rollers rest on a receiving table 14, which is configured trough-like, so that the rollers can not unintentionally roll down from the receiving table 14.
  • the roller removal device 2 may be placed on runways or rails and be displaceable by means of wheels in the direction of arrow z.
  • the roller removal device 2 comprises a transfer device 15, with which the rollers 11 can be transferred to a receiving device 21.
  • the receiving device can transfer the rollers, for example, to a transport device for removal or further transport or to a packaging machine for packaging the rollers.

  • a drive is provided, which is not shown in the figures.
  • a sliding device 20 is provided between two carriages.
  • This comprises in the illustrated embodiment, a curved rod 18, which - seen in the y-direction, with its apex, which is approximately centrally located between the carriage 16, the trough of the receiving table 14 and thus the rollers is closest. Looking from there in the direction of the carriage, the rod thus assumes an ever-increasing distance to the rollers 11.
  • Arranged freely rotatably on the rod are small rollers 19, which in their entirety describe along the convex shape formed by the rod. Instead of the rollers and small wheels can be provided. It is advantageous if the rollers or rollers 19 or the wheels are very smooth and thus when touching the rollers 11 this add no damage.
  • the carriages can carry a supporting element 25, which - like the receiving table 14 - is configured trough-like and on which still empty winding tubes 7 are placed. These empty cores 7 are available for a roll change.
  • Roller removal device 2 may further be adapted to tilt the receiving table 14.
  • a device not shown in detail for providing a tilting force is provided, wherein this then acts so that the pusher 20 remote from side 22 of the receiving table is lowered and / or the pusher 20 facing side 23 of the receiving table is raised (with ā€œfacing" and ā€œturned awayā€ from the direction of view of the rollers 11 is to be understood), so that thereby the rollers can roll from the receiving table.
  • nubs 24 The side facing away from the sliding device 22 of the receiving table 14 is provided with nubs 24, which rise from the surface of the receiving table 14. These nubs 24 are advantageously lined up along a line which is substantially parallel to the trough. These nubs can be inserted and fixed in holes of the receiving table. But they can also be integrally formed with the receiving table.
  • the winding shaft 12 with the finished coils 11 is deposited on the receiving table 14 by a device, not shown, that the winding shaft 12 is received by the holder 13. Now, the entire roller picking device 2 is moved in the direction of the arrow z. Since the holder is immovable at least in the axial direction of the rollers 11 or at least held immovable, the winding shaft 12 is pulled out of the winding tubes by the displacement. The rollers 11 now experience only a supporting force, which is applied by the receiving table 14. In the FIG. 2 is shown that the roller picking device 2 has been moved to the full travel.
  • the transfer device 15 is moved in the direction of the arrow y, so that now the displacement device 20 comes into operative connection with the rollers, wherein the rollers 19 comes into touching contact with the rollers 11.
  • a contact is first with the rollers 11, which are arranged in the region of the apex of the displacement device. These are thus placed in a rolling motion about their rolling axes.
  • this movement is superimposed by a rotational movement about a vertical axis associated with the respective roller 11, which is essentially caused by the fact that the contact initially acts only in the region of one end of a roller and, as a rule, less force has to be expended for the described rotation of this roller as for moving or pushing away the rollers.
  • the nubs described above are provided. On these run the roles, so that the twisting is facilitated. However, it may also occur the reverse case, after which the rollers are first pushed away a bit and then - after the emergence of the respective role on one or more knobs - are rotated due to the temporarily reduced static friction force.
  • the effect is that the roll axes of the rollers are now no longer aligned, so no longer take an angle of 180 degrees. Rather, the axes of rotation now form a family of tangents which run along a line analogous to the rod 18. These axes of rotation thus each take an angle of less than 180 degrees. Overall, this results in the rollers rolling in slightly different directions. These rolling directions are in the FIG. 3 indicated by the arrows 26. As a rule, the rolling directions each represent a normal to the roll axis of the respective roll. Because of this described arrangement of the roll axes, a running apart of the rolls 11 during unwinding can be observed. A tilting of the rollers when unrolling and thus a risk of damage are thus reliably avoided.
  • tilting of the receiving table 14 can still have a supporting effect.
  • This procedure is advantageous because then the Shifting device does not have to apply all the force alone to move the rollers 11 into motion. Too much pressure applied to the rollers by the rollers 19 could damage them. In addition, without the support of the dumping, the rod 18 would probably have to be made more massive.
  • FIG. 4 now shows the situation in which the rollers are completely and completely unrolled on the receiving device 21.
  • the FIG. 4 further shows that the transfer device 15 has been moved so far in the direction of the arrow y, that the axes of the winding tubes 7 and the axis of the winding shaft 12 are aligned.
  • the winding tubes and the winding shaft were aligned with each other, wherein pushing the winding tubes 7 on the winding shaft 12 by moving the winding tubes 7 in the axial direction (direction -z) causes the pushing.
  • This process is in the FIG. 5 shown.
  • This is again a stocked with empty cores winding shaft available that can be passed with appropriate facilities back to the winding device 1, which is not shown here in detail. It is now possible to carry out the next winding change.
  • the FIG. 6 clarifies once again the positions of the roles after the change in position.
  • the two rollers 11 are additionally characterized in this figure by their rolling axes 27, which represent their main axes of inertia.
  • the rolling axes 27 (shown by broken lines) assume an angle ā‡ , which according to the invention is less than 180 degrees after the change in position. This means at the same time that the direction of movement indicated by the arrows 26 are no longer parallel to each other, but diverge.

Description

Die Erfindung betrifft eine Rollenentnahmeeinrichtung nach dem Oberbegriff des Anspruchs 1, eine Wickeleinrichtung nach dem Oberbegriff des Anspruchs 15 sowie ein Verfahren nach dem Oberbegriff des Anspruchs 16.The invention relates to a roller removal device according to the preamble of claim 1, a winding device according to the preamble of claim 15 and a method according to the preamble of claim 16.

Mehrere Rollen, auf die beispielsweise bahnfƶrmige Folie, insbesondere bahnfƶrmige Kunststofffolie aufgewickelt ist, werden oft auf einer Wickelwelle gehalten, um mehrere Nutzen gleichzeitig be- oder verarbeiten, beispielsweise aufwickeln, zu kƶnnen.Several rolls on which, for example, sheet-like film, in particular sheet-like plastic film is wound up, are often held on a winding shaft in order to process or process several uses at the same time, for example by being able to wind up.

AnschlieƟend mĆ¼ssen diese Rollenwickel von der Wickelwelle abgezogen und neuen Rollenwickel auf die Wickelwelle aufgeschoben werden. Diesem Zweck dient im Allgemeinen eine Verlagerungseinrichtung, mit welcher die Rollenwickel relativ zur Wickelwelle verlagerbar sind. Diese Verlagerungseinrichtung kann eine AuflageflƤche umfassen, auf welchen die Rollenwickel aufliegen. Aufgrund der Haftreibung zwischen Rollenwickel und AuflageflƤche werden die Rollenwickel durch ein axiales Verfahren der AuflageflƤche von der Wickelwelle abgezogen. UnterstĆ¼tzend kƶnnen auch Halteelemente vorgesehen werden, die ein Verrutschen der Rollenwickel auf der AuflageflƤche vermeiden.Subsequently, these reel rolls must be subtracted from the winding shaft and pushed onto the reel shaft new roll reel. This purpose is generally served by a displacement device, with which the roller windings are displaceable relative to the winding shaft. This displacement device may comprise a bearing surface on which rest the roll winding. Due to the static friction between roller winding and bearing surface, the roller windings are removed by an axial process of the bearing surface of the winding shaft. Supporting can also be provided retaining elements, which prevent slippage of the roll winding on the support surface.

Die Rollenwickel sind dann einer Aufnahmeeinrichtung zuzufĆ¼hren, welche die Rollen aufnehmen, so dass sie anschlieƟend beispielsweise weitertransportiert, gesammelt oder verpackt werden kƶnnen.The roll wraps are then to be supplied to a receiving device, which receive the rolls so that they can subsequently be transported, collected or packaged, for example.

Von der Verlagerungseinrichtung auf die Aufnahmeeinrichtung werden die Rollen durch eine Ɯbergabeeinrichtung Ć¼berfĆ¼hrt, wobei die Rollen zumindest bereichsweise frei rollbar sind. Dies erfolgt beispielsweise durch eine DrĆ¼ckvorrichtung oder ein Abkippen der Verlagerungseinrichtung oder durch eine Kombination aus beidem.From the displacement device to the receiving device, the rollers are transferred by a transfer device, wherein the rollers are at least partially freely rollable. This is done for example by a pressing device or tilting of the displacement device or by a combination of both.

Die DE 10 2013 108 831 A1 zeigt eine solche Vorrichtung, bei der ein Abkippen der Rollen von einer Aufnahmeeinheit erfolgt.The DE 10 2013 108 831 A1 shows such a device in which a tilting of the rollers takes place by a receiving unit.

Die EP 0 905 070 A1 und die DE 10 2010 003 947 A1 zeigen jeweils einen Tragwalzenwickler, bei dem nebeneinander einzelne Wickel erzeugt werden, die jedoch nicht auf einer gemeinsamen Wickelwelle angeordnet sind. Ein paar Tragwalzen bilden ein Tragbett, in der die Wickel aufliegen. Hier erfolgt das AusstoƟen aus dem Tragbett durch Ɯberwinden des Widerstands, welcher durch eine der Tragwalzen gebildet wird.The EP 0 905 070 A1 and the DE 10 2010 003 947 A1 each show a carrier roll winder, in which individual wraps are produced side by side, but which are not arranged on a common winding shaft. A few support rollers form a carrying bed in which the reels rest. Here, the ejection from the support bed by overcoming the resistance, which is formed by one of the support rollers.

Die WO 99/29480 zeigt eine Vorrichtung, bei der die Wickel auf eine gebogene OberflƤche aufrollen, die die Wickel nach oben hin auffƤchern. Es wird mittels einer Kamera geprĆ¼ft, ob die einzelnen Wickel voneinander separiert sindThe WO 99/29480 shows a device in which the rolls roll up on a curved surface, which fan the wraps upwards. It is checked by means of a camera, whether the individual coils are separated from each other

Problematisch dabei ist jedoch, dass sich beim freien Rollen die Stirnseiten der Rollen verhaken kƶnnen, so dass ein geradliniges Abrollen nicht gewƤhrleistet ist, was letztendlich zur BeschƤdigung des auf den Rollen aufgewickelten Wickelguts fĆ¼hren kann.The problem with this is, however, that can catch the faces of the roles in the free roles, so that a straight rolling is not guaranteed, which can ultimately lead to damage of the wound on the rolls of winding material.

Die Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung und ein Verfahren vorzuschlagen, so dass derartige BeschƤdigungen vermieden werden.The object of the present invention is therefore to propose an apparatus and a method so that such damage is avoided.

ErfindungsgemƤƟ wird diese Aufgabe durch sƤmtliche Merkmale der AnsprĆ¼che 1, 15 und 16 gelƶst. In den abhƤngigen AnsprĆ¼chen, in den Figuren und in der Beschreibung sind mƶgliche Ausgestaltungen der Erfindung angegeben. Dabei gelten Merkmale, die im Zusammenhang mit den erfindungsgemƤƟen Vorrichtungen angegeben sind, auch im Zusammenhang mit dem erfindungsgemƤƟen Verfahren und umgekehrt, so dass wechselweise auf die jeweiligen Merkmale zurĆ¼ckgegriffen wird bzw. werden kann.According to the invention this object is achieved by all features of claims 1, 15 and 16. In the dependent claims, in the figures and in the description of possible embodiments of the invention are given. In this case, features that are associated with the invention Devices are given, also in connection with the inventive method and vice versa, so that alternately recourse to the respective features or can be.

GemƤƟ der Erfindung ist eine Einrichtung zur LageverƤnderung der Rollachsen der Rollen vorgesehen, mit welcher die Rollachsen zweier benachbarter Rollen auf einen Winkel von weniger als 180 Grad bringbar sind.According to the invention, a device for changing the position of the rolling axes of the rollers is provided, with which the rolling axes of two adjacent rollers can be brought to an angle of less than 180 degrees.

Wenn die Rollen sich noch auf der Wickelwelle befinden oder kurz nach dem Abschieben hiervon, nehmen die Rollachsen zweier benachbarter Rollen einen Winkel von 180 Grad ein. Die Rollachse einer Rolle ist dabei die Richtung der HaupttrƤgheitsachse dieser Rolle. Um diese Rollachse rollt die Rolle, wenn sie mit ihrer UmfangsoberflƤche auf einer Unterlage in einer Rollrichtung abrollt. Wenn die Rollachsen zweier benachbarter Rollen einen Winkel von weniger als 180 Grad einnehmen, so bedeutet das, dass die Rollrichtungen nicht parallel liegen, sondern einen Winkel grĆ¶ĆŸer als 0 Grad zueinander einnehmen. In diesem Fall rollen die Rollen auseinander, so dass sich ihre Stirnseiten voneinander entfernen. In diesem Fall werden trotz des freien Rollens eine BerĆ¼hrung und damit eine Verkantung effektiv vermieden, so dass eine BeschƤdigung des Wickelguts nahezu vollstƤndig ausgeschlossen ist.When the rollers are still on the winding shaft or shortly after being pushed off, the rolling axles of two adjacent rollers make an angle of 180 degrees. The roll axis of a roll is the direction of the main axis of inertia of this role. The roll rolls around this roll axis as it rolls on a base in a roll direction with its peripheral surface. When the roll axes of two adjacent rolls angle less than 180 degrees, this means that the rolling directions are not parallel, but occupy an angle greater than 0 degrees to each other. In this case, the rollers roll apart so that their faces are separated. In this case, despite the free rolling a touch and thus jamming effectively avoided, so that damage to the winding material is almost completely excluded.

In einer vorteilhaften AusfĆ¼hrungsform umfasst die Erfindung eine Einrichtung zum Beschleunigen der Rollen. Damit ist gemeint, dass eine Kraft auf die Rollen einwirkt, um diesen eine Rollrichtung zu geben. In diesem Fall ist es auf einfache Weise mƶglich, die Rollachsen von jeweils zwei benachbarten Rollen auf einen Winkel von weniger als 180 Grad zu bringen.In an advantageous embodiment, the invention comprises a device for accelerating the rollers. By this is meant that a force acts on the rollers to give them a rolling direction. In this case, it is easily possible to bring the rolling axes of each two adjacent rollers to an angle of less than 180 degrees.

In einer weiteren vorteilhaften AusfĆ¼hrungsform der Erfindung umfasst die Einrichtung zum Beschleunigen der Rollen eine Einrichtung zum Kippen einer AuflageflƤche, auf welcher die Rollen aufliegen. Dabei verlƤuft die Kippachse parallel oder im Wesentlichen parallel zu der axialen Erstreckung der Wickelwelle. Diese AusfĆ¼hrungsform ist besonders dann vorteilhaft, wenn die AuflageflƤche abgewinkelt ist, so dass sie eine Mulde parallel zur axialen Richtung der Wickelwelle bildet. In diesem Fall kƶnnen die Rollen bei der Relativbewegung zur Wickelwelle nicht seitlich wegrollen. Ein Kippen der AuflageflƤche bewirkt nun, dass zum Bewegen Rollen diesen keine potentielle Energie zum Ɯberwinden der Seiten der Mulde zugefĆ¼hrt werden muss.In a further advantageous embodiment of the invention, the means for accelerating the rollers comprises means for tilting a support surface on which the rollers rest. The tilting axis is parallel or substantially parallel to the axial extent of the winding shaft. This embodiment is particularly advantageous when the support surface is angled so that it forms a trough parallel to the axial direction of the winding shaft. In this case, the rollers can not roll laterally during the relative movement to the winding shaft. A tilting of the support surface now causes that moving these rollers no potential energy must be supplied to overcome the sides of the trough.

Es ist besonders vorteilhaft, wenn die Einrichtung zur LageverƤnderung der Rollachsen der Rollen zumindest eine Verschiebeeinrichtung mit wenigstens einem Verschiebeelement umfasst, welches entlang einer konvex verlaufenden Linie angeordnet ist. "Konvex" bedeutet in diesem Zusammenhang, dass die Enden der Linie von den Rollen, deren Rollachsen noch einen Winkel von 180 Grad einnehmen, weiter entfernt sind als die Mitte der Linie. Mit dieser Verschiebeeinrichtung kƶnnen nun die Rollen auf eine besonders einfache Weise derart beeinflusst werden, dass die Rollachsen zweier benachbarter Rollen auf einen Winkel von weniger als 180 Grad bringbar sind. Aufgrund der TrƤgheit der Rollen wird ein Verschiebeelement mit einer konvex verlaufenden Linie eine Rolle zunƤchst, da das Verschiebelement nur einen BerĆ¼hrungspunkt oder eine kurze BerĆ¼hrungslinie mit der Rolle hat, diese im Wesentlichen zunƤchst um eine vertikale Achse drehen, bevor die Rolle abrollt. Damit das Drehen zuverlƤssig vor dem Abrollen erfolgt, ist es vorteilhaft, wenn diese Verschiebeeinrichtung mit der vorgenannten Einrichtung zum Kippen zusammenwirkt. In diesem Fall kann vorgesehen sein, dass zunƤchst das Verschiebeelement auf die Rollen einwirkt, bevor die Einrichtung zum Kippen betƤtigt wird, welches das Abrollen der Rollen hervorruft.It is particularly advantageous if the device for changing the position of the rolling axes of the rollers comprises at least one displacement device with at least one displacement element which is arranged along a convexly extending line. "Convex" in this context means that the ends of the line are further away from the rollers whose roll axes are still at an angle of 180 degrees than the center of the line. With this displacement device, the rollers can now be influenced in a particularly simple manner such that the rolling axes of two adjacent rollers can be brought to an angle of less than 180 degrees. Due to the inertia of the rollers is a sliding element with a convex running Line a role initially, since the sliding element has only one point of contact or a short line of contact with the roller, these rotate substantially first about a vertical axis before the roller rolls off. So that the rotation takes place reliably before rolling, it is advantageous if this displacement device cooperates with the aforementioned means for tilting. In this case, it may be provided that initially the displacement element acts on the rollers before the device for tilting is actuated, which causes the rolling of the rollers.

Eine besonders bevorzugte Ausgestaltung der Erfindung beinhaltet ein Rohr, eine Stange und/oder einen Stab, welche konvex geformt sein kƶnnen. Damit ist ein einfaches Element zur VerfĆ¼gung gestellt, welches auf mehrere Rollen einwirken kann. Dabei ist es bevorzugt, dass die konvexe Form zumindest in der Projektion in der Rollebene der Rollen verlƤuft, so dass der bereits oben beschriebene Effekt (Verdrehen der Rollen um eine vertikale Achse) auch eintritt.A particularly preferred embodiment of the invention includes a tube, a rod and / or a rod, which may be convex. Thus, a simple element is provided, which can act on several roles. It is preferred that the convex shape extends at least in the projection in the roller plane of the rollers, so that the effect already described above (rotation of the rollers about a vertical axis) also occurs.

In einer weiteren oder anderen Ausgestaltung der Erfindung ist vorgesehen, dass das Verschiebeelement eine Rolle oder Walze umfasst, deren Drehachse tangential zu der konvex verlaufenden Linie angeordnet ist oder parallel zu dieser Tangente liegt. Eine Rolle oder Walze bietet den Vorteil, dass sie auf den Rollen abrollen, so dass das Wickelgut, welches sich auf den Rollen befindet, so dass das Wickelgut mƶglichst wenig beeintrƤchtigt wird.In a further or other embodiment of the invention, it is provided that the displacement element comprises a roller or roller whose axis of rotation is arranged tangentially to the convex line or is parallel to this tangent. A roller or roller has the advantage that they roll on the rollers, so that the winding material, which is located on the rollers, so that the winding material is affected as little as possible.

In weiterer vorteilhafter Ausgestaltung kann eine solche Rolle frei drehbar gelagert und/oder antreibbar sein. Eine freie Drehbarkeit dient der leichten Abrollbarkeit auf der Rolle, wogegen ein Antrieb dazu dienen kann, die Rollen in eine Abrollbewegung zu versetzen.In a further advantageous embodiment, such a roller can be freely rotatably mounted and / or driven. Free rotation allows for easy unrollability on the roll whereas a drive can serve to translate the rolls into a rolling motion.

Weiterhin kann vorgesehen sein, dass die Rollen oder Walze eine UmfangsoberflƤche aufweist, die zumindest bereichsweise aus Teflon besteht. Damit wird die Haftung zwischen dem Wickelgut und der Rolle bzw. Walze weiter reduziert, um die BeschƤdigungsgefahr weiter zu verringern.Furthermore, it can be provided that the rollers or roller has a peripheral surface, which consists at least partially of Teflon. Thus, the adhesion between the winding material and the roller or roller is further reduced in order to further reduce the risk of damage.

In einer besonders bevorzugten AusfĆ¼hrungsform der Erfindung ist vorgesehen, dass die Verlagerungseinrichtung und/oder die Aufnahmeeinrichtung Erhƶhungen umfasst, mit welchen der Reibkontakt der Rollen zur Verlagerungseinrichtung und/oder zur Aufnahmeeinrichtung zumindest kurzzeitig reduzierbar ist. Dabei weisen die OberflƤchen der Erhƶhungen bevorzugt kleine FlƤchen auf, so dass die KontaktflƤche der Rolle mit der Aufnahmeeinrichtung und/oder der Verlagerungseinrichtung reduziert ist. Auf diese Weise wird der Reibkontakt verringert. Eine einzelne Rolle lƤuft also auf eine oder mehrere dieser Erhƶhungen hinauf, wobei die KontaktflƤche nur noch einen geringen Teil der vorherigen KontaktflƤche darstellt. Der groƟe Vorteil entsteht insbesondere dann, wenn nun die Rolle um eine vertikale Achse gedreht wird. Mit anderen Worten sind die Erhƶhungen insbesondere dann von Vorteil, wenn auf die Rollen mit einem Verschiebeelement eingewirkt wird, deren zumindest eine Verschiebeelement entlang einer konvex verlaufenden Linie angeordnet ist.In a particularly preferred embodiment of the invention, provision is made for the displacement device and / or the receiving device to comprise elevations with which the frictional contact of the rollers with respect to the displacement device and / or the receiving device can be reduced at least for a short time. In this case, the surfaces of the elevations preferably have small areas, so that the contact surface of the roller with the receiving device and / or the displacement device is reduced. In this way, the frictional contact is reduced. A single roll thus runs up to one or more of these elevations, wherein the contact surface is only a small part of the previous contact surface. The big advantage arises especially when now the roll is rotated about a vertical axis. In other words, the elevations are advantageous in particular when the rollers are acted upon by a displacement element whose at least one displacement element is arranged along a convexly extending line.

Vorteilhaft ist dabei, wenn zumindest ein Teil der Erhƶhungen in die Verlagerungseinrichtung und/oder die Aufnahmeeinrichtung eingearbeitet ist. Das bedeutet, dass diese Einrichtungen und die Erhƶhungen aus demselben Material bestehen und die Erhƶhungen beispielsweise durch PrƤgungen in das Material eingebracht sind. Dies kann eine Vorgehensweise zu einer einfachen Herstellung sein.It is advantageous if at least a portion of the elevations in the displacement device and / or the receiving device is incorporated. This means that these devices and the elevations are made of the same material and the elevations are introduced, for example, by imprints in the material. This can be a procedure for a simple production.

Da jedoch ein gewisser VerschleiƟ an den Erhƶhungen unvermeidbar erscheint, ist es vorteilhaft, wenn zumindest einen Teil der Erhƶhungen als separate Bauteile in oder an die Verlagerungseinrichtung und/oder die Aufnahmeeinrichtung vorgesehen ist, welche hier ein- oder angesetzt sind. Eine Auswechselbarkeit ist damit gegeben. Auch kƶnnen andere, geeignete Materialien vorgesehen sein, die den Rollen einen geringen Reibungswiderstand bieten.However, since some wear on the ridges appears unavoidable, it is advantageous if at least a portion of the ridges is provided as separate components in or on the displacement device and / or the receiving device, which are here on or attached. A replaceability is given. Also, other suitable materials may be provided which provide the rollers with low frictional resistance.

So ist es vorteilhaft, wenn zumindest ein Teil der Erhƶhungen wenigstens teilweise Teflon umfasst. Dieses Material bietet einen besonders geringen Reibungswiderstand.Thus, it is advantageous if at least some of the elevations at least partially comprise Teflon. This material offers a particularly low frictional resistance.

In einer vorteilhaften AusfĆ¼hrungsform der erfindungsgemƤƟen Rollenentnahmeeinrichtung ist vorgesehen, dass die Einrichtung zur LageverƤnderung der Rollachsen der Rollen an einer Verfahreinrichtung angeordnet ist, mit welcher diese quer zur Achse der Wickelwelle verfahrbar ist. Diese Verfahreinrichtung kann als Konkretisierung der bereits oben genannten Verschiebeeinrichtung aufgefasst werden, wobei die Verfahreinrichtung im Wesentlichen eine Linearbewegung vollfĆ¼hren kann. FĆ¼r eine solche Liniearbewegung kƶnnen vielfƤltige Antriebe vorgesehen werden. Bevorzugt ist jedoch wenigstens ein druckluftbetƤtigbarer Zylinder, der in der Anschaffung und im Unterhalt gĆ¼nstig ist.In an advantageous embodiment of the roller removal device according to the invention it is provided that the device for changing the position of the rolling axes of the rollers is arranged on a displacement device with which it is movable transversely to the axis of the winding shaft. This traversing device can be understood as a concretization of the displacement device already mentioned above, wherein the traversing device can essentially perform a linear movement. For such a linear movement, a variety of drives can be provided. However, at least one cylinder which can be actuated by compressed air and which is inexpensive to purchase and to maintain is preferred.

In einer die Erfindung verbessernden MaƟnahme ist vorgesehen, dass die Verfahreinrichtung beidseits der AuflageflƤche angeordnete Schienen umfasst, auf welchen die Schlitten verschiebbar sind. Die Schlitten tragen dabei - direkt oder indirekt - die Einrichtung zur LageverƤnderung der Rollachsen der Rollen.In a measure improving the invention, it is provided that the traversing device comprises rails arranged on both sides of the support surface, on which the carriages are displaceable. The carriages carry - directly or indirectly - the device for changing the position of the rolling axes of the rollers.

Die Aufgabe der Erfindung wird - wie bereits oben angegeben - auch durch ein Verfahren gelƶst, bei mittels einer Einrichtung zur LageverƤnderung der Rollachsen der Rollen die Rollachsen zweier benachbarter Rollen auf einen Winkel von weniger als 180 Grad zueinander gebracht werden.The object of the invention is - as already stated above - also solved by a method in which the rolling axes of two adjacent rollers are brought to an angle of less than 180 degrees to each other by means of a device for changing the position of the rollers.

Figur 1 zeigt eine Wickelvorrichtung 1 und eine Rollenentnahmevorrichtung 2. In der Wickelvorrichtung 1 umfasst als Komponenten zwei Teile eines Maschinengestells 3, 4, in denen auf nicht dargestellte Art eine BahnfĆ¼hrungswalze 5 gelagert ist, welche die letzte Walze darstellt, Ć¼ber die die wenigstens eine Materialbahn lƤuft, bevor letztere den eigentlichen Wickel erreicht. Dabei ist die BahnfĆ¼hrungswalze 5 oft nicht direkt in diesen Teilen des Maschinengestells gelagert. Sie kann auch in Zwischengestellen gelagert sein, um relativ zum Maschinengestell verschiebbar zu sein. Die genannte BahnfĆ¼hrungswalze 5 kann eine Kontaktwalze sein. Mit einer solchen Kontaktwalze wird die Materialbahn so an den Wickel herangefĆ¼hrt, dass eine definierte Menge an Luft zwischen den einzelnen Lagen des Wickels eingewickelt wird. Dazu wird ein definierter Abstand zwischen der BahnfĆ¼hrungswalze und dem Wickel hergestellt. FIG. 1 shows a winding device 1 and a roller removal device 2. In the winding device 1 comprises as components two parts of a machine frame 3, 4, in which in a manner not shown, a web guide roller 5 is mounted, which is the last roller over which runs the at least one material web, before the latter reaches the actual winding. The web guide roller 5 is often not stored directly in these parts of the machine frame. It can also be mounted in intermediate frames to be displaceable relative to the machine frame. Said web guide roller 5 may be a contact roller. With such a contact roller, the material web is brought to the winding so that a defined amount of air is wrapped between the individual layers of the coil. For this purpose, a defined distance between the web guide roll and the winding is produced.

Weiterhin ist eine Wickelwelle 6 zu sehen. Zwar ist diesbezĆ¼glich ebenfalls dargestellt, dass diese Wickelwelle 6 in den Teilen des Maschinengestells 3, 4 gelagert ist, jedoch ist dies eine vereinfachte Darstellung. In der Regel ist die Wickelwelle in Hilfsgestellen gelagert, so dass die Wickelwelle radial und/oder in Umfangsrichtung der BahnfĆ¼hrungswalze bewegbar ist. Die Bewegung in Umfangsrichtung ist beispielsweise bei einem automatischen Rollenwechsel notwendig. Die Einstellung in radialer Richtung relativ zur BahnfĆ¼hrungswalze 5 ist notwendig, um den bereits oben beschriebenen definierten Abstand zwischen der BahnfĆ¼hrungswalze 5 und der Wickelwelle 6 einstellen zu kƶnnen.Furthermore, a winding shaft 6 can be seen. Although it is also shown in this regard that this winding shaft 6 is mounted in the parts of the machine frame 3, 4, but this is a simplified representation. In general, the winding shaft is mounted in auxiliary racks, so that the winding shaft is movable radially and / or in the circumferential direction of the web guide roller. The movement in the circumferential direction is necessary, for example, in an automatic roll change. The adjustment in the radial direction relative to the web guide roller 5 is necessary in order to adjust the already described above defined distance between the web guide roller 5 and the winding shaft 6.

Die Wickelwelle 6 trƤgt eine oder mehrere WickelhĆ¼lsen 7, wobei im vorliegenden AusfĆ¼hrungsbeispiel vier WickelhĆ¼lsen vorgesehen sind. Auf den WickelhĆ¼lsen sind im dargestellten Zeitpunkt bereits einige Lagen der Materialbahnen aufgewickelt worden, wobei jeder WickelhĆ¼lse 7 eine Materialbahn 8 zugeordnet ist. Eine WickelhĆ¼lse 7 und der zugeordnete und bereits aufgewickelte Teil der Materialbahn 8 bilden einen Wickel 9, der weiter oben vorwiegend als Rolle bezeichnet wird. Die Materialbahnen 8 werden in der Regel aus einer einzigen, nicht dargestellten Materialbahn erzeugt. Um eine BerĆ¼hrung der RƤnder der in einzelne Materialbahnen 8 getrennte Materialbahn und damit eine BeschƤdigung zu verhindern, sind die Materialbahnen 8 mit einem Abstand 10 zueinander auf der BahnfĆ¼hrungswalze 5 angeordnet. Dieser Abstand wird oft dadurch hergestellt, dass ein schmaler Streifen aus der einzelnen Materialbahn zwischen zwei der Materialbahnen 8 zur Erzeugung dieser herausgeschnitten und abgefĆ¼hrt wird. Die einzelnen WickelhĆ¼lsen 7 berĆ¼hren sich jedoch einander, so dass letztlich die Stirnseiten der WickelhĆ¼lsen Ć¼ber die Stirnseiten der aufgewickelten Materialbahn hinaus reichen.The winding shaft 6 carries one or more winding tubes 7, wherein four winding tubes are provided in the present embodiment. Some layers of the material webs have already been wound on the winding tubes in the time shown, wherein each winding tube 7 a Material web 8 is assigned. A winding tube 7 and the associated and already wound part of the web 8 form a winding 9, which is mainly referred to above as a role. The material webs 8 are generally produced from a single material web, not shown. In order to prevent contact of the edges of the web of material separated into individual material webs 8 and thus damage, the webs of material 8 are arranged at a distance 10 from each other on the web guide roll 5. This distance is often produced by cutting out and removing a narrow strip from the individual material web between two of the material webs 8 to produce it. The individual winding tubes 7, however, touch each other so that ultimately the end faces of the cores extend beyond the end faces of the wound material web.

Auf der Rollenentnahmevorrichtung 2, die in der Figur 1 gegenĆ¼berliegend der Wickelvorrichtung 1 dargestellt ist, befinden sich aus der Wickelvorrichtung 1 entnommene, fertig gewickelte Wickel oder Rollen 11, deren WickelhĆ¼lsen noch auf der zugehƶrigen Wickelwelle 12 aufgeschoben bzw. die Wickelwelle 12 noch in den WickelhĆ¼lsen eingeschoben ist. Die Wickelwelle 12 ist dabei einendig in einem Halter 13 gehalten, wobei Wickelwelle 12 und Halter 13 miteinander kuppelbar und damit voneinander trennbar sind, so dass der Halter 13 jeweils eine Wickelwelle mit fertig gewickelten Rollen aus der Wickeleinrichtung 1 Ć¼bernehmen kann.On the roller removal device 2, which in the FIG. 1 opposite to the winding device 1 is shown, are taken from the winding device 1, finished wound winding or rollers 11, the cores still pushed onto the associated winding shaft 12 and the winding shaft 12 is still inserted into the cores. The winding shaft 12 is held at one end in a holder 13, wherein the winding shaft 12 and holder 13 are coupled together and thus separated from each other, so that the holder 13 can each take a winding shaft with finished wound rollers from the winding device 1.

Der Halter 13 kann wegen des im allgemeinen hohen Gewichts der Rollen diese nicht Ć¼ber die Wickelwelle halten, vielmehr liegen die Rollen auf einem Aufnahmetisch 14 auf, der muldenartig ausgestaltet ist, so dass die Rollen nicht unbeabsichtigt vom Aufnahmetisch 14 herunterrollen kƶnnen.Because of the generally high weight of the rollers, the holder 13 can not hold it over the winding shaft; rather, the rollers rest on a receiving table 14, which is configured trough-like, so that the rollers can not unintentionally roll down from the receiving table 14.

Die Rollenentnahmeeinrichtung 2 kann auf Rollbahnen oder Schienen aufgestellt sein und mittels RƤder in Richtung des Pfeils z verschiebbar sein.The roller removal device 2 may be placed on runways or rails and be displaceable by means of wheels in the direction of arrow z.

Weiterhin umfasst die Rollenentnahmeeinrichtung 2 eine Ɯbergabeeinrichtung 15, mit welcher die Rollen 11 an eine Aufnahmeeinrichtung 21 Ć¼bergebbar sind. die Aufnahmeeinrichtung kann die Rollen beispielsweise einer Transporteinrichtung zum Ab- oder Weitertransport oder einer Verpackungsmaschine zum Verpacken der Rollen Ć¼bergeben. Die Aufnahmeeinrichtung kann auch selbst die Weitertransportfunktion Ć¼bernehmen.Furthermore, the roller removal device 2 comprises a transfer device 15, with which the rollers 11 can be transferred to a receiving device 21. the receiving device can transfer the rollers, for example, to a transport device for removal or further transport or to a packaging machine for packaging the rollers. The receiving device can also take over the onward transport function itself.

Die Ɯbergabeeinrichtung 15 umfasst als Kernelemente Schlitten 16, die auf beidseits des Aufnahmetisches 14 angeordneten Schienen 17 verschiebbar sind. Hier ist ein Antrieb vorgesehen, der jedoch in den Figuren nicht dargestellt ist. Zwischen zwei Schlitten ist eine Schiebevorrichtung 20 vorgesehen. Diese umfasst im dargestellten AusfĆ¼hrungsbeispiel eine gebogene Stange 18, die - in y-Richtung gesehen, mit ihrem Scheitelpunkt, der in etwa mittig zwischen den Schlitten 16 liegt, der Mulde des Aufnahmetisches 14 und damit den Rollen am nƤchsten ist. Von dort aus in Richtung der Schlitten blickend nimmt die Stange also einen immer grĆ¶ĆŸer werdenden Abstand zu den Rollen 11 ein. Frei drehbar auf der Stange angeordnet sind kleine Walzen 19, die in ihrer Gesamtheit entlang der durch die Stange gebildete konvexe Form beschreiben. Anstelle der Rollen kƶnnen auch kleine RƤdchen vorgesehen sein. Von Vorteil ist es, wenn die Walzen oder Rollen 19 bzw. die RƤdchen sehr leichtgƤngig sind und damit beim BerĆ¼hren der Rollen 11 diesen keine BeschƤdigungen hinzufĆ¼gen.The transfer device 15 comprises, as core elements, carriages 16 which are displaceable on rails 17 arranged on both sides of the receiving table 14. Here, a drive is provided, which is not shown in the figures. Between two carriages a sliding device 20 is provided. This comprises in the illustrated embodiment, a curved rod 18, which - seen in the y-direction, with its apex, which is approximately centrally located between the carriage 16, the trough of the receiving table 14 and thus the rollers is closest. Looking from there in the direction of the carriage, the rod thus assumes an ever-increasing distance to the rollers 11. Arranged freely rotatably on the rod are small rollers 19, which in their entirety describe along the convex shape formed by the rod. Instead of the rollers and small wheels can be provided. It is advantageous if the rollers or rollers 19 or the wheels are very smooth and thus when touching the rollers 11 this add no damage.

Die Schlitten kƶnnen darĆ¼ber hinaus noch ein Tragelement 25 tragen, welches - Ƥhnlich wie der Aufnahmetisch 14 - muldenartig ausgestaltet ist und auf welchem noch leere WickelhĆ¼lsen 7 aufgelegt werden. Diese leeren WickelhĆ¼lsen 7 stehen fĆ¼r einen Wickelwechsel zur VerfĆ¼gung.In addition, the carriages can carry a supporting element 25, which - like the receiving table 14 - is configured trough-like and on which still empty winding tubes 7 are placed. These empty cores 7 are available for a roll change.

Rollenentnahmeeinrichtung 2 kann weiterhin dazu ausgebildet sein, den Aufnahmetisch 14 zu kippen. Dazu ist eine nicht nƤher gezeigte Einrichtung zur Bereitstellung einer Kippkraft vorgesehen, wobei diese dann so wirkt, dass die der Schiebevorrichtung 20 abgewandte Seite 22 des Aufnahmetisches abgesenkt und/oder die der Schiebevorrichtung 20 zugewandte Seite 23 des Aufnahmetisches angehoben wird (wobei sich "zugewandt" und "abgewandt" aus Blickrichtung der Rollen 11 zu verstehen ist), so dass dadurch die Rollen vom Aufnahmetisch abrollen kƶnnen.Roller removal device 2 may further be adapted to tilt the receiving table 14. For this purpose, a device not shown in detail for providing a tilting force is provided, wherein this then acts so that the pusher 20 remote from side 22 of the receiving table is lowered and / or the pusher 20 facing side 23 of the receiving table is raised (with "facing" and "turned away" from the direction of view of the rollers 11 is to be understood), so that thereby the rollers can roll from the receiving table.

Die der Schiebevorrichtung abgewandte Seite 22 des Aufnahmetisches 14 ist mit Noppen 24 versehen, die sich aus der OberflƤche des Aufnahmetisches 14 erheben. Diese Noppen 24 sind vorteilhafterweise entlang einer Linie, die im Wesentlichen parallel zu der Mulde verlƤuft, aufgereiht. Diese Noppen kƶnnen in Bohrungen des Aufnahmetisches eingesteckt und befestigt sein. Sie kƶnnen aber auch einstĆ¼ckig mit dem Aufnahmetisch ausgebildet sein.The side facing away from the sliding device 22 of the receiving table 14 is provided with nubs 24, which rise from the surface of the receiving table 14. These nubs 24 are advantageously lined up along a line which is substantially parallel to the trough. These nubs can be inserted and fixed in holes of the receiving table. But they can also be integrally formed with the receiving table.

Ein Rollenwechsel und insbesondere die Ɯbergabe der Rollen 11 an die Aufnahmeeinrichtung 21 werden nun anhand der Figuren 1 bis 5 beschrieben. Im Vorfeld des Rollenwechsels in der Wickelvorrichtung 1 wird die Wickelwelle 12 etwas von der BahnfĆ¼hrungswalze abgestellt, so dass ein Spalt entsteht. Etwas stromaufwƤrts wird die neue Wickelwelle 6 mit den bereits aufgeschobenen WickelhĆ¼lsen 7 an die Materialbahnen 8 angestellt. Nun erfolgt ein trennender Schnitt der Materialbahnen 8 und ein Anwickeln der neu gebildeten MaterialbahnanfƤnge auf die WickelhĆ¼lsen 7. Eine Haftung dieser BahnanfƤnge auf den neuen WickelhĆ¼lsen 7 erfolgt in bekannter Weise beispielsweise mittels Kleber oder durch elektrostatische KrƤfte. Die Wickelwelle 12 mit den fertig gestellten Wickeln 11 wird durch eine nicht gezeigte Vorrichtung auf dem Aufnahmetisch 14 abgelegt, dass die Wickelwelle 12 von dem Halter 13 aufgenommen wird. Nun wird die gesamte Rollenentnahmeeinrichtung 2 in Richtung des Pfeils z bewegt. Da der Halter zumindest in axialer Richtung der Rollen 11 unverschieblich ist oder wenigstens unverschieblich gehalten wird, wird durch die Verschiebung auch die Wickelwelle 12 aus den WickelhĆ¼lsen herausgezogen. Die Rollen 11 erfahren nunmehr lediglich eine UnterstĆ¼tzungskraft, die von dem Aufnahmetisch 14aufgebracht wird. In der Figur 2 ist dargestellt, dass die Rollenentnahmeeinrichtung 2 um den vollstƤndigen Verfahrweg verschoben wurde.A role change and in particular the transfer of the rollers 11 to the receiving device 21 will now be based on the FIGS. 1 to 5 described. In advance of the roll change in the winding device 1, the winding shaft 12 is turned off slightly from the web guide roller, so that a gap is formed. Slightly upstream of the new winding shaft 6 is employed with the already deferred winding tubes 7 to the webs 8. Now, a separating cut of the webs 8 and a winding of the newly formed material web starts on the winding tubes 7. An adhesion of this web beginnings on the new cores 7 is carried out in a known manner, for example by means of adhesive or by electrostatic forces. The winding shaft 12 with the finished coils 11 is deposited on the receiving table 14 by a device, not shown, that the winding shaft 12 is received by the holder 13. Now, the entire roller picking device 2 is moved in the direction of the arrow z. Since the holder is immovable at least in the axial direction of the rollers 11 or at least held immovable, the winding shaft 12 is pulled out of the winding tubes by the displacement. The rollers 11 now experience only a supporting force, which is applied by the receiving table 14. In the FIG. 2 is shown that the roller picking device 2 has been moved to the full travel.

Nun wird, wie es in der Figur 3 dargestellt ist, die Ɯbergabeeinrichtung 15 in Richtung des Pfeils y bewegt, so dass nun die Verschiebeeinrichtung 20 in Wirkverbindung mit den Rollen tritt, wobei die Walzen 19 in berĆ¼hrenden Kontakt mit den Rollen 11 kommt. Dabei erfolgt eine BerĆ¼hrung zunƤchst mit den Rollen 11, die im Bereich des Scheitelpunkts der Verschiebeeinrichtung angeordnet sind. Diese werden damit in eine Rollbewegung um ihre Rollachsen versetzt. Dieser Bewegung Ć¼berlagert ist jedoch eine Drehbewegung um eine der jeweiligen Rolle 11 zugeordnete Vertikalachse, die im Wesentlichen dadurch hervorgerufen wird, dass der BerĆ¼hrkontakt zunƤchst nur im Bereich eines Endes einer Rolle wirkt und fĆ¼r das beschriebene Verdrehen dieser Rolle in der Regel weniger Kraft aufgewendet werden muss als fĆ¼r das Verschieben bzw. WegdrĆ¼cken der Rollen. Um die Verdrehkraft gering zu halten, sind die weiter oben beschriebenen Noppen vorgesehen. Auf diese laufen die Rollen auf, so dass das Verdrehen erleichtert wird. Es kann jedoch auch der umgekehrte Fall eintreten, wonach die Rollen zunƤchst etwas weggedrĆ¼ckt werden und dann - nach dem Auflaufen der jeweiligen Rolle auf eine oder mehrere Noppen - aufgrund der nun temporƤr verringerten Haftreibekraft verdreht werden.Well, as it is in the FIG. 3 is shown, the transfer device 15 is moved in the direction of the arrow y, so that now the displacement device 20 comes into operative connection with the rollers, wherein the rollers 19 comes into touching contact with the rollers 11. In this case, a contact is first with the rollers 11, which are arranged in the region of the apex of the displacement device. These are thus placed in a rolling motion about their rolling axes. However, this movement is superimposed by a rotational movement about a vertical axis associated with the respective roller 11, which is essentially caused by the fact that the contact initially acts only in the region of one end of a roller and, as a rule, less force has to be expended for the described rotation of this roller as for moving or pushing away the rollers. To keep the twisting power low, the nubs described above are provided. On these run the roles, so that the twisting is facilitated. However, it may also occur the reverse case, after which the rollers are first pushed away a bit and then - after the emergence of the respective role on one or more knobs - are rotated due to the temporarily reduced static friction force.

Bei weiterer Bewegung der Verschiebeeinrichtung werden auch alle weiteren Rollen auf die beschriebene Weise erfasst.Upon further movement of the displacement device all other roles are detected in the manner described.

UnabhƤngig davon, ob nun zuerst das WegdrĆ¼cken oder das Verdrehen auftritt, ist der Effekt, dass die Rollachsen der Rollen nun nicht mehr miteinander fluchten, also nicht mehr einen Winkel von 180 Grad einnehmen. Vielmehr bilden die Drehachsen nun eine Schar von Tangenten, die entlang einer analog zur Stange 18 gebogenen Linie verlaufen. Diese Drehachsen nehmen also untereinander jeweils einen Winkel von weniger als 180 Grad ein. Insgesamt hat dies zur Folge, dass die Rollen in leicht unterschiedliche Richtungen Rollen. Diese Rollrichtungen sind in der Figur 3 mit den Pfeilen 26 angedeutet. Die Rollrichtungen stellen im Regelfall jeweils eine Normale zur der Rollachse der jeweiligen Rolle dar. Aufgrund dieser beschriebenen Anordnung der Rollachsen ist ein Auseinanderlaufen der Rollen 11 beim Abrollen zu beobachten. Ein Verkanten der Rollen beim Abrollen und damit eine BeschƤdigungsgefahr werden damit zuverlƤssig vermieden.Regardless of whether the first pushing away or twisting occurs, the effect is that the roll axes of the rollers are now no longer aligned, so no longer take an angle of 180 degrees. Rather, the axes of rotation now form a family of tangents which run along a line analogous to the rod 18. These axes of rotation thus each take an angle of less than 180 degrees. Overall, this results in the rollers rolling in slightly different directions. These rolling directions are in the FIG. 3 indicated by the arrows 26. As a rule, the rolling directions each represent a normal to the roll axis of the respective roll. Because of this described arrangement of the roll axes, a running apart of the rolls 11 during unwinding can be observed. A tilting of the rollers when unrolling and thus a risk of damage are thus reliably avoided.

Bei dem beschriebenen Vorgang kann ein Abkippen des Aufnahmetisches 14 noch unterstĆ¼tzend einwirken. Dieses Vorgehen ist vorteilhaft, da dann die Verschiebeeinrichtung nicht gƤnzlich alleine die Kraft zum Inbewegungsetzen der Rollen 11 aufbringen muss. Ein zu starker durch die Walzen 19 aufgebrachter Druck auf die Rollen kƶnnten diese beschƤdigen. AuƟerdem mĆ¼sste ohne die UnterstĆ¼tzung durch das Abkippen mƶglicherweise die Stange 18 massiver ausgestaltet sein.In the described process, tilting of the receiving table 14 can still have a supporting effect. This procedure is advantageous because then the Shifting device does not have to apply all the force alone to move the rollers 11 into motion. Too much pressure applied to the rollers by the rollers 19 could damage them. In addition, without the support of the dumping, the rod 18 would probably have to be made more massive.

Die Figur 4 zeigt nun die Situation, in der die Rollen vollstƤndig und vollzƤhlig auf die Aufnahmeeinrichtung 21 abgerollt sind. Die Figur 4 zeigt weiterhin, dass die Ɯbergabeeinrichtung 15 soweit in Richtung des Pfeils y bewegt wurde, dass die Achsen der WickelhĆ¼lsen 7 und die Achse der Wickelwelle 12 miteinander fluchten. Mit anderen Worten wurden die WickelhĆ¼lsen und die Wickelwelle aufeinander ausgerichtet, wobei ein Aufschieben der WickelhĆ¼lsen 7 auf die Wickelwelle 12 durch ein Verschieben der WickelhĆ¼lsen 7 in deren axialer Richtung (Richtung -z) das Aufschieben bewirkt. Dieser Vorgang ist in der Figur 5 dargestellt. Damit steht wieder eine mit leeren WickelhĆ¼lsen bestĆ¼ckte Wickelwelle zur VerfĆ¼gung, die mit entsprechenden Einrichtungen wieder an die Wickelvorrichtung 1 Ć¼bergeben werden kann, was hier aber nicht nƤher dargestellt ist. Es besteht nunmehr die Mƶglichkeit, den nƤchsten Wickelwechsel durchzufĆ¼hren.The FIG. 4 now shows the situation in which the rollers are completely and completely unrolled on the receiving device 21. The FIG. 4 further shows that the transfer device 15 has been moved so far in the direction of the arrow y, that the axes of the winding tubes 7 and the axis of the winding shaft 12 are aligned. In other words, the winding tubes and the winding shaft were aligned with each other, wherein pushing the winding tubes 7 on the winding shaft 12 by moving the winding tubes 7 in the axial direction (direction -z) causes the pushing. This process is in the FIG. 5 shown. This is again a stocked with empty cores winding shaft available that can be passed with appropriate facilities back to the winding device 1, which is not shown here in detail. It is now possible to carry out the next winding change.

Die Figur 6 verdeutlicht noch einmal die Lagen der Rollen nach der LageverƤnderung. Die beiden Rollen 11 sind in dieser Figur zusƤtzlich durch ihre Rollachsen 27 charakterisiert, die ihre HaupttrƤgheitsachsen darstellen. Die Rollachsen 27 (mit unterbrochenen Linien dargestellt) nehmen einen Winkel Ī± ein, der nach der LageverƤnderung erfindungsgemƤƟ kleiner als 180 Grad ist. Das bedeutet gleichzeitig, dass die durch die Pfeile 26 angedeuteten Bewegungsrichtungen nicht mehr parallel zueinander sind, sondern auseinander laufen.The FIG. 6 clarifies once again the positions of the roles after the change in position. The two rollers 11 are additionally characterized in this figure by their rolling axes 27, which represent their main axes of inertia. The rolling axes 27 (shown by broken lines) assume an angle Ī±, which according to the invention is less than 180 degrees after the change in position. This means at the same time that the direction of movement indicated by the arrows 26 are no longer parallel to each other, but diverge.

Auf die beschriebene Weise ist nicht nur eine Rollenentnahmeeinrichtung geschaffen worden, sondern auch ein Wickelsystem mit einer Wickelwechselvorrichtung und einer Rollenentnahmeeinrichtung.
