Description
Die vorliegende Erfindung betrifft eine Hilfsvorrichtung zum Ausrichten einer Wickelhülse sowie ein Verfahren zum Ausrichten einer Wickelhülse.The present invention relates to an auxiliary device for aligning a winding tube and a method for aligning a winding tube.
In Fertigungsverfahren, in denen das Produkt auf einer Hülse aufgewickelt wird, da es sich zum Beispiel um ein Produkt mit einer weiten, aber flachen Erstreckung handelt, werden derartige Hülsen regelmäßig ausgetauscht. Ein solcher Austausch kann beispielsweise erfolgen, weil eine zuvor umwickelte Hülse mit einer bestimmten Menge des Produktes umwickelt ist, oder aber auch wenn ein nur zum Teil fertig produzierter Wickel, aufweisend das Produkt und die Hülse, als Ausschuss aussortiert wird. Dies kann z.B. aufgrund eines Abrisses des Produktes vorgesehen sein. Ein beispielhafter Produktionsprozess ist die Folienherstellung, bei welcher eine Hülse mit Folie umwickelt wird, bis ein vorgegebener Produktumfang gegeben ist. Für den Austausch wird eine zweite Wickelhülse auf einer separaten Hülsenaufnahme platziert, sodass diese automatisch oder manuell beispielsweise durch Verdrehen eines Maschinenteils, welches die vorbereitende und die im Betrieb befindliche Aufnahme umfasst, austauschbar ist. Da jedoch in einer derartigen Wickelmaschine auch unterschiedliche Breiten des Produktes produziert werden, ist eine Hülsenaufnahme häufig breiter ausgeführt als eine aufzunehmende Hülse, sodass für den Austausch zwischen der vorbereitenden Hülse und der sich in Produktion befindlichen Hülse beide Hülsen aneinander ausgerichtet werden, damit auch das nachfolgende Produkt definiert auf der Hülse angeordnet ist.In manufacturing processes in which the product is wound on a sleeve, for example because it is a product with a wide but flat extension, such sleeves are replaced regularly. Such an exchange can be done, for example, because a previously wrapped sleeve is wrapped with a certain amount of the product, or even if a completely finished produced coil, comprising the product and the sleeve, is sorted out as broke. This may be provided, for example, due to a tear of the product. An exemplary production process is the film production, in which a sleeve is wrapped with foil until a given product scope is given. For replacement, a second winding tube is placed on a separate sleeve receptacle so that it is automatically or manually interchangeable, for example by rotating a machine part, which includes the preparatory and in-service recording. However, since different widths of the product are produced in such a winding machine, a sleeve receptacle is often made wider than a male sleeve, so that for the exchange between the preparatory sleeve and the sleeve in production both sleeves are aligned with each other, so that the subsequent Product defined on the sleeve.
So kann es beispielsweise erforderlich sein, dass das Aufwickeln des Produktes auf die Hülse mittig erfolgt, damit an den Enden des Wickels jeweils ein Teil der Hülse herausragt und der Wickel in einem späteren Prozessschritt aufgenommen werden kann. Um ein derartiges Ausrichten durchführen zu können, werden häufig beim Abnehmen der vorherigen Hülse auf einer Hülsenaufnahme die Endpunkte der alten Hülse markiert, was beispielsweise manuell durch Einfügen einer Kerbe auf der Hülsenaufnahme möglich ist. Dieser manuelle Vorgang ist jedoch aufwendig, da jeweils neue Markierungen notwendig sind, welche, sofern diese nicht entfernt werden, zusätzlich eine Unübersichtlichkeit fördern, da die Zuordnung der letzten, "korrekten" Kerbe mit zunehmender Anzahl schwieriger wird. Ferner klettert der Bediener gegebenenfalls in die Maschine, um einen Referenzpunkt zu finden. Dies ist jedoch umständlich, da in einer derartigen Produktionsmaschine häufig wenig Platz ist.Thus, it may be necessary, for example, that the winding of the product onto the sleeve takes place centrally, so that in each case a part of the sleeve protrudes at the ends of the roll and the roll can be taken up in a later process step. In order to carry out such an alignment, the end points of the old sleeve are often marked when removing the previous sleeve on a sleeve receptacle, which is possible, for example manually by inserting a notch on the sleeve receptacle. However, this manual process is expensive, since new markings are necessary, which, if they are not removed, additionally promote confusion, since the assignment of the last, "correct" notch becomes more difficult as the number increases. Further, if necessary, the operator climbs into the machine to find a reference point. However, this is cumbersome because there is often little room in such a production machine.
Ferner sind starre Vorrichtungen bekannt, welche an einer festen Position in einer Wickelmaschine befestigt werden, sodass pro Vorrichtung eine bestimmte Ausrichtung einer Wickelhülse angefahren werden kann. Derartige Vorrichtungen sind jedoch, insbesondere in Hinblick auf wechselnde Produktgrößen oder unterschiedliche Wickelhülsen unflexibel. So ist jede der starren Vorrichtungen oft nur für eine einzelne Wickelhülsengröße an der Maschine einsetzbar, da die feste Position nicht veränderbar ist.Furthermore, rigid devices are known, which are fastened to a fixed position in a winding machine, so that per device, a specific orientation of a winding tube can be approached. However, such devices are inflexible, in particular with regard to changing product sizes or different cores. Thus, each of the rigid devices is often used only for a single winding tube size on the machine, since the fixed position is not changeable.
Es ist Aufgabe der vorliegenden Erfindung, voranstehende aus dem Stand der Technik bekannte Nachteile zumindest teilweise zu beheben. Insbesondere ist es die Aufgabe der vorliegenden Erfindung, ein Ausrichten einer Wickelhülse zu vereinfachen und dabei das Ausrichten der Wickelhülse bei geringen Kosten sicher und flexibel zu gewährleisten.It is an object of the present invention, at least partially overcome the above known from the prior art disadvantages. In particular, it is the task of present invention, to facilitate an alignment of a winding tube, while ensuring the alignment of the winding tube at low cost safely and flexibly.
Die voranstehende Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 und ein Verfahren mit den Merkmalen des Anspruchs 14.The above object is achieved by a device having the features of
Weitere Merkmale und Details der Erfindung ergeben sich aus den Unteransprüchen, der Beschreibung und den Zeichnungen. Dabei gelten Merkmale und Details, die im Zusammenhang mit der erfindungsgemäßen Vorrichtung beschrieben worden sind, selbstverständlich auch im Zusammenhang mit dem erfindungsgemäßen Verfahren und jeweils umgekehrt, sodass bezüglich der Offenbarung zu den einzelnen Erfindungsaspekten stets wechselseitig Bezug genommen wird bzw. werden kann.Further features and details of the invention will become apparent from the dependent claims, the description and the drawings. In this case, features and details that have been described in connection with the device according to the invention apply, of course, also in connection with the method according to the invention and in each case vice versa, so that with respect to the disclosure of the individual aspects of the invention always reciprocal reference is or may be.
Erfindungsgemäß umfasst eine Hilfsvorrichtung zum Ausrichten einer Wickelhülse an einer Referenz einen Hilfskörper mit einem Anschlagmittel, das zur Anlage an einem Gegenanschlagmittel der Wickelhülse ausgebildet ist. Ferner ist umfasst die Hilfsvorrichtung ein Ausrichtmittel, welches zum Ausrichten der Wickelhülse an der Referenz geeignet ist. Das Anschlagmittel und das Ausrichtmittel weisen weiterhin eine bestimmbare Relation zueinander auf. Insbesondere kann die Hilfsvorrichtung zum Ausrichten einer Wickelhülse auf einer Hülsenaufnahme einer Wickelmaschine geeignet sein. Vorzugsweise handelt es sich bei der Wickelmaschine um eine Wickelmaschine zur Folienherstellung.According to the invention, an auxiliary device for aligning a winding tube at a reference comprises an auxiliary body with a stop means, which is designed to rest against a counter stop means of the winding tube. Furthermore, the auxiliary device comprises an alignment means, which is suitable for aligning the winding tube to the reference. The stop means and the alignment means further have a determinable relation to each other. In particular, the auxiliary device may be suitable for aligning a winding tube on a sleeve receptacle of a winding machine. The winding machine is preferably a winding machine for producing films.
Somit handelt es sich bei der Wickelhülse vorzugsweise um eine Hülse, auf welche eine Folie wickelbar ist, sodass ein Transport und/oder Weiterverkauf derselben möglich ist. Ferner kann unter der Wickelhülse eine Hülse verstanden werden, die alleine zur Aufnahme eines Produktwickels geeignet ist oder eine Hülse, die mit anderen Hülsen die Basis für einen Produktwickel bildet. Unter einem Anschlagmittel bzw. einem Gegenanschlagmittel kann vorzugsweise eine flache Ausbildung des Hilfskörpers bzw. der Wickelhülse verstanden werden. So kann als Anschlagmittel beispielsweise ein Absatz in der Form des Hilfskörpers oder ein Absatz am Hilfskörper vorgesehen sein, welcher mit einer Stirnfläche der Wickelhülse zur Anlage bringbar ist und damit wirken kann. Es sind jedoch auch weitere Formen von Gegenanschlagmittel und Anschlagmittel denkbar, wie beispielsweise eine runde Form, wobei vorzugsweise das Anschlagmittel und das Gegenanschlagmittel zueinander korrespondierend ausgebildet sein können. Insbesondere kann die Form des Anschlagmittels einer Negativform des Gegenanschlagmittels entsprechen. Weiterhin kann das Anschlagmittel auch ein zusätzliches Bauteil umfassen, welches an einem Befestigungsabschnitt des Hilfskörpers direkt oder indirekt angeordnet ist. Unter einem Ausrichtmittel kann im Sinne der vorliegenden Erfindung vorzugsweise ein Hilfsmittel verstanden werden, um die Position der Hilfsvorrichtung und damit insbesondere der Wickelhülse relativ zur Referenz in Bezug auf zumindest eine Richtung zu bestimmen. Somit kann es sich bei dem Ausrichtmittel beispielsweise um ein Peilmittel handeln, mit welchem der Bediener die Referenz anvisieren kann. Dadurch kann der Bediener z.B. eine Information über die aktuelle Positionierung der Hilfsvorrichtung bzw. der Wickelhülse relativ zur Referenz erhalten. Dabei sind jedoch auch weitere Formen des Ausrichtmittels denkbar, wie beispielsweise ein Stab, insbesondere ein Teleskopstab, welcher von der Hilfsvorrichtung in die Wickelmaschine hineinreicht und damit nah an die Referenz oder in Anlage an die Referenz bringbar ist. Die Referenz kann dabei ein bestimmter Punkt, eine bestimmte Stelle oder ein bestimmter Bereich sein. Vorzugsweise kann es sich bei der Referenz um das Ende einer zweiten, insbesondere im Produktionsbetrieb befindlichen, Wickelhülse oder eine Position in bestimmter Entfernung zu dem Ende der zweiten Wickelhülse handeln. Somit kann das Ausrichten der Wickelhülse ein Verschieben der Wickelhülse, insbesondere zusammen mit der Hilfsvorrichtung umfassen, bis die Referenz durch das Ausrichtmittel anpeilbar ist. Somit ist ebenfalls für das Ausrichten der Wickelhülse wichtig, dass die Relation zwischen Anschlagmittel und Ausrichtmittel bestimmbar ist. Unter einer derartigen bestimmbaren Relation kann zum Beispiel eine maßliche Relation verstanden werden, welche insbesondere messbar ist. Ferner sind aber auch weitere bestimmbare Relationen denkbar, beispielsweise kann das Bestimmen der Relation durch Ablesen einer Skala erfolgen, die vorzugsweise auf dem Hilfskörper angebracht ist, oder die Relation kann elektronisch ermittelbar sein. Hier sind jedoch auch weitere Möglichkeiten, die Relation zu bestimmen, denkbar. Unter einem Hilfskörper kann vorzugsweise ein Hauptkörper der Hilfsvorrichtung verstanden werden, welcher insbesondere die Form der Hilfsvorrichtung zumindest im Wesentlichen bestimmt. So kann dieser beispielsweise ein ein- oder mehrteiliges Gehäuse umfassen, welches Teile der Hilfsvorrichtung vor Umwelteinflüssen schützt. Innerhalb der Wickelmaschine kann die Wickelhülse ferner auf der Hülsenaufnahme gegen Verschieben befestigbar sein. So kann beispielsweise eine Spannvorrichtung in der Wickelhülse oder in der Hülsenaufnahme vorgesehen sein, um die Befestigung insbesondere nach erfolgreichem Ausrichten der Wickelhülse, zu gewährleisten und damit für den weiteren Produktionsprozess an der ausgerichteten Stelle auf der Hülsenaufnahme zu sichern.Thus, the winding tube is preferably a sleeve, on which a film can be wound, so that a transport and / or resale of the same is possible. Further, under the winding tube, a sleeve can be understood, which is suitable alone for receiving a product roll or a sleeve which forms the basis for a product roll with other sleeves. A stop means or a counter stop means may preferably be understood to mean a flat configuration of the auxiliary body or of the winding tube. Thus, as a stop means, for example, a paragraph in the form of the auxiliary body or a shoulder may be provided on the auxiliary body, which can be brought into contact with an end face of the winding tube and thus act. However, other forms of counter stop means and stop means are conceivable, such as a round shape, wherein preferably the stop means and the counter stop means may be formed corresponding to each other. In particular, the shape of the stop means may correspond to a negative form of the counter stop means. Furthermore, the stop means may also comprise an additional component which is arranged directly or indirectly on a fixing portion of the auxiliary body. In the context of the present invention, an alignment means can preferably be understood to mean an aid in order to determine the position of the auxiliary device and thus, in particular, of the winding sleeve relative to the reference with respect to at least one direction. Thus, the alignment means can be, for example, a direction finding device with which the operator can aim for the reference. As a result, the operator can receive, for example, information about the current positioning of the auxiliary device or the winding tube relative to the reference. However, other forms of alignment are conceivable, such as a rod, in particular a telescopic rod, which extends from the auxiliary device in the winding machine and thus can be brought close to the reference or in Appendix to the reference. The reference can be a specific point, a specific point or a specific area. The reference may preferably be the end of a second, in production production, winding tube or a position at a certain distance from the end of the second winding tube. Thus, the alignment of the winding tube may comprise a displacement of the winding tube, in particular together with the auxiliary device, until the reference can be detected by the alignment means. Thus, it is also important for the alignment of the winding tube, that the relation between the stop means and aligning means can be determined. By such a determinable relation can be understood, for example, a dimensional relation, which is measurable in particular. Furthermore, other determinable relations are also conceivable, for example, the determination of the relation can be made by reading a scale, which is preferably mounted on the auxiliary body, or the relation can be determined electronically. But here are other ways to determine the relation conceivable. An auxiliary body may preferably be understood to mean a main body of the auxiliary device, which determines in particular at least substantially the shape of the auxiliary device. For example, this may comprise a single-part or multi-part housing which protects parts of the auxiliary device from environmental influences. Within the winding machine, the winding tube can also be fastened on the sleeve receptacle against displacement. Thus, for example, a clamping device may be provided in the winding tube or in the sleeve receptacle to the Fixing especially after successful alignment of the winding tube, to ensure and thus secure for the further production process at the aligned location on the sleeve receptacle.
Eine erfindungsgemäße Hilfsvorrichtung ist damit einfach zu handhaben und für unterschiedliche Wickelhülsen und damit auch unterschiedliche Referenzen einsetzbar, sodass ein flexibler Einsatz im Produktionsprozess, insbesondere von Folien, ermöglicht sein kann. Dabei ermöglicht die Hilfsvorrichtung insbesondere ein Ausrichten der Wickelhülse im Betrieb, sodass sich beispielsweise die Fertigstellung eines in Betrieb befindlichen Wickels einer zweiten Wickelhülse noch im Prozess befinden kann, während das Ausrichten der Wickelhülse erfolgt. Somit kann die Produktionszeit im Herstellungsprozess verkürzt sein. Dadurch, dass das Ausrichten der Wickelhülse vorteilhafterweise in einer Entfernung zur Referenz stattfinden kann, kann weiterhin die Sicherheit der Wickelmaschine gesteigert sein.An auxiliary device according to the invention is thus easy to handle and can be used for different cores and thus also different references, so that a flexible use in the production process, in particular of films, may be possible. In this case, the auxiliary device allows in particular an alignment of the winding tube during operation, so that, for example, the completion of an operating winding of a second winding tube may still be in the process while the alignment of the winding tube takes place. Thus, the production time in the manufacturing process can be shortened. The fact that the alignment of the winding tube can advantageously take place at a distance from the reference, the safety of the winding machine can be further increased.
Im Rahmen der Erfindung kann ferner vorteilhafterweise vorgesehen sein, dass es sich bei dem Ausrichtmittel um ein optisches und/oder akustisches Ausrichtmittel handelt. Unter einem optischen Ausrichtmittel kann beispielsweise ein Leuchtmittel verstanden werden, welches Licht aussendet, so dass die Position des Ausrichtmittels mit der Referenz abgleichbar ist. Es ist jedoch weiterhin denkbar, dass das optische Ausrichtmittel ein Fokussierungselement ist. Das Fokussierungselement kann beispielsweise eine Linse sein, durch welche ein Bediener hindurchblicken kann, um die Wickelhülse so lange verschieben zu können, bis die Referenz angepeilt bzw. in einem bestimmten Bereich der Linse sichtbar ist. Unter einem akustischen Ausrichtmittel kann ferner beispielsweise verstanden werden, dass ein Signalton ertönt, sobald das Ausrichtmittel eine bestimmte Position im Verhältnis zur Referenz erreicht hat. So könnte beispielsweise ein optisches Ausrichtmittel mit einem akustischen Ausrichtmittel kombiniert sein, sodass ein Lichttaster bei Erreichen der Referenz ein Signal an eine Elektronik der Hilfsvorrichtung oder des Ausrichtmittels abgibt und das Ausrichtmittel daraufhin den Signalton erzeugt. Optische und/oder akustische Ausrichtmittel haben insbesondere den Vorteil, dass diese berührungslos arbeiten können. Dadurch kann eine hohe Reichweite des Ausrichtmittels erreicht werden, sodass das Ausrichten der Wickelhülse in Entfernung zum Produktionsprozess stattfinden kann. Dadurch können die Sicherheit, die Komfortabilität sowie die Flexibilität beim Ausrichten der Wickelhülse gesteigert sein.In the context of the invention may also be advantageously provided that it is the alignment means is an optical and / or acoustic alignment. By an optical alignment means, for example, a light source can be understood which emits light, so that the position of the alignment means can be adjusted with the reference. However, it is still conceivable that the optical alignment means is a focusing element. The focusing element can be, for example, a lens through which an operator can look through in order to be able to displace the winding tube until the reference is targeted or visible in a specific region of the lens. An acoustic alignment means may further be understood to mean, for example, that a beep sounds as soon as the alignment means has reached a certain position in relation to the reference. Thus, for example, an optical alignment means could be combined with an acoustic alignment means, so that a light scanner emits a signal to an electronics of the auxiliary device or the alignment means upon reaching the reference and the alignment means then generates the acoustic signal. Optical and / or acoustic alignment means have the particular advantage that they can operate without contact. As a result, a high range of alignment can be achieved, so that the alignment of the winding tube can take place at a distance from the production process. This allows the Safety, comfort and flexibility in aligning the winding tube be increased.
Es ist des Weiteren vorteilhafterweise denkbar, dass das Ausrichtmittel bei einer erfindungsgemäßen Hilfsvorrichtung ein Lichtabgabemodul umfasst, wobei das Lichtabgabemodul insbesondere einen Laser aufweist. Dabei kann durch das Lichtabgabemodul die Positionierung des Ausrichtmittels und damit des Anschlagmittels bzw. der Wickelhülse einem Bediener aufgezeigt werden. Ein Laser kann dabei vorteilhafterweise eine hohe Intensität der Lichtabgabe aufweisen, sodass auch bei unterschiedlichen Lichtbedingungen noch eine sichtbare und zuverlässige Ausrichthilfe gewährleistet ist. Insbesondere durch eine scharfe Abgrenzung des Lasers bzw. des durch den Laser bestrahlten Bereiches kann außerdem eine hohe Genauigkeit beim Ausrichten gegeben sein. Vorteilhafterweise kann es sich bei dem Laser um einen kreuz- oder punktförmigen Laser handeln. Vorzugsweise strahlt das Lichtabgabemodul, insbesondere der Laser, jedoch einen linienförmigen Bereich aus, sodass eine exakte Positionierung der Hilfsvorrichtung, insbesondere auf dem Umfang der Wickelhülse, nicht notwendig ist, sodass das Ausrichten weiter vereinfacht sein kann, wenn das Anschlagmittel mit dem Gegenanschlagmittel in Anlage gebracht ist.Furthermore, it is advantageously conceivable that the alignment means in an auxiliary device according to the invention comprises a light-emitting module, the light-emitting module in particular having a laser. In this case, the positioning of the alignment means and thus of the stop means or the winding tube to an operator can be indicated by the light emission module. A laser can advantageously have a high intensity of the light output, so that a visible and reliable alignment is guaranteed even under different lighting conditions. In particular, by a sharp demarcation of the laser or the irradiated by the laser area can also be given a high accuracy in alignment. Advantageously, the laser may be a cross or point laser. Preferably, however, the light emitting module, in particular the laser, radiates a linear area, so that an exact positioning of the auxiliary device, in particular on the circumference of the winding tube, is not necessary, so that the alignment can be further simplified when the stop means brought into abutment with the counter stop means is.
Vorteilhafterweise kann bei einer erfindungsgemäßen Hilfsvorrichtung vorgesehen sein, dass das Anschlagmittel am Gegenanschlagmittel zumindest im Wesentlichen in einer Anlageebene anlegbar ist und das Ausrichtmittel derart angeordnet ist, dass das Ausrichtmittel und die Referenz zumindest im Wesentlichen in einer parallelen oder identischen Ebene mit der Anschlagebene liegen, wenn die Wickelhülse ausgerichtet ist. Insbesondere können das Ausrichtmittel und die Referenz auch vollständig in einer parallelen oder identischen Ebene mit der Anschlagebene liegen, wenn die Wickelhülse ausgerichtet ist. Dadurch kann vorzugsweise ein Anpeilen der Referenz in der Ebene erfolgen, sodass die Relation zwischen Ausrichtmittel und Anschlagmittel besonders einfach bestimmbar ist und damit das Ausrichten insgesamt vereinfacht sein kann.Advantageously, it may be provided in an auxiliary device according to the invention that the stop means on the counter stop means at least substantially in a contact plane can be applied and the alignment is arranged such that the alignment and the reference are at least substantially in a parallel or identical plane with the stop plane, if the winding tube is aligned. In particular, the alignment means and the reference may also lie completely in a parallel or identical plane with the stop plane when the winding tube is aligned. As a result, it is preferably possible for the reference to be targeted in the plane, so that the relation between the alignment means and the stop means can be determined particularly easily and thus the alignment can be simplified as a whole.
Im Rahmen der Erfindung kann die Hilfsvorrichtung zum Ausrichten der Wickelhülse ferner vorteilhafterweise mobil einsetzbar sein. Dabei kann insbesondere ein Sicherungselement vorgesehen sein, durch das der Hilfskörper an einer Wickelmaschine sicherbar ist. Unter einer mobilen Einsetzbarkeit kann dabei verstanden werden, dass die Hilfsvorrichtung tragbar bzw. transportabel ist und damit insbesondere von der Wickelmaschine separierbar ist bzw. unabhängig von der Wickelmaschine einsetzbar ist. Somit kann es sich vorzugsweise bei der Hilfsvorrichtung um ein Handgerät handeln. Dadurch kann die Hilfsvorrichtung besonders flexibel einsetzbar sein und eine besonders leichte Handhabung, zum Beispiel beim Einsatz in unterschiedlichen Maschinen, aufweisen. Auch ein eventueller Austausch der Hilfsvorrichtung kann dadurch besonders einfach möglich sein. Durch das Sicherungselement kann die Hilfsvorrichtung an der Wickelmaschine befestigbar sein bzw. mit dieser verbindbar sein. So kann beispielsweise als Sicherungselement ein Schlüsselring oder eine einfache Durchgangsbohrung vorgesehen sein. Dadurch kann die Hilfsvorrichtung über ein zusätzliches Sicherungsmittel, beispielsweise ein Seil, einen Draht oder dergleichen an der Wickelmaschine, insbesondere lösbar, befestigbar sein, sodass eine Sicherung gegen Herunterfallen oder Verlorengehen bei gleichzeitigem Erhalten der Flexibilität gewährleistet sein kann.In the context of the invention, the auxiliary device for aligning the winding tube can also advantageously be used mobile. In this case, in particular, a securing element can be provided by which the auxiliary body can be secured on a winding machine. Under a mobile applicability can be understood that the auxiliary device is portable or transportable and thus in particular separable from the winding machine and is independent of the winding machine used. Thus, the auxiliary device may preferably be a hand-held device. As a result, the auxiliary device can be used particularly flexibly and can be particularly easy to handle, for example when used in different machines. Even a possible replacement of the auxiliary device can be particularly easily possible. By the securing element, the auxiliary device can be fastened to the winding machine or be connected to this. For example, a key ring or a simple through hole may be provided as a securing element. Thereby, the auxiliary device via an additional securing means, such as a rope, a wire or the like on the winding machine, in particular releasably be fastened, so that a safeguard against falling or getting lost while maintaining flexibility can be ensured.
Eine erfindungsgemäße Hilfsvorrichtung kann ferner vorzugsweise ein Kanalelement aufweisen, das zur Aufnahme der Wickelhülse geeignet ist. Ein derartiges Kanalelement kann einseitig offen sein und damit beispielsweise durch eine Aussparung im Hilfskörper, von diesem abstehende Stege, zusätzliche Wandungen oder dergleichen gebildet sein. Dadurch kann ein Platzieren der Hilfsvorrichtung auf der Wickelhülse und damit ein besonders einfaches in Anlage Bringen des Anschlagmittels und des Gegenanschlagmittels gewährleistet sein. Ferner kann dadurch ermöglicht sein, dass bei korrekter Platzierung die Hilfsvorrichtung in Bezug auf die Wickelhülse nur noch einen rotatorischen Freiheitsgrad aufweist, wenn das Kanalelement an der Wickelhülse und der Anschlag am Gegenanschlag der Wickelhülse angelegt ist. Durch die dadurch ermöglichte einfache Relation der Hilfsvorrichtung bzw. der Wickelhülse zur Referenz kann das Ausrichten der Wickelhülse weiter vereinfacht sein.An auxiliary device according to the invention may further preferably have a channel element which is suitable for receiving the winding tube. Such a channel element may be open on one side and thus be formed, for example, by a recess in the auxiliary body, of this projecting webs, additional walls or the like. Thereby, a placement of the auxiliary device on the winding tube and thus a particularly easy to bring in conditioning the stop means and the counter-stop means can be ensured. Furthermore, this can be made possible that when correctly placed, the auxiliary device with respect to the winding tube only has a rotational degree of freedom when the channel element is applied to the winding tube and the stop on the counter-stop of the winding tube. As a result of the simple relationship of the auxiliary device or the winding tube to the reference, the alignment of the winding tube can be further simplified.
Vorteilhafterweise kann bei einer erfindungsgemäßen Hilfsvorrichtung das Kanalelement eine Kanalachse aufweisen, und das Anschlagmittel und/oder das Ausrichtmittel parallel zur Kanalachse verstellbar sein. Unter der Kanalachse kann eine Erstreckungsachse des Kanalelementes verstanden werden, welche vorzugsweise parallel zur Zylinderachse bzw. Hülsenachse der Wickelhülse ausgerichtet ist, wenn die Hilfsvorrichtung auf der Wickelhülse zum Ausrichten der Wickelhülse positioniert ist. Unter einer Verstellbarkeit kann dabei verstanden werden, dass das Anschlagmittel und/oder das Ausrichtmittel beispielsweise lose verschiebbar oder durch einen Antrieb verschiebbar ist. Ein derartiger Antrieb kann beispielsweise ein Spindelantrieb sein, welcher von Hand oder durch eine Energieeinheit getrieben wirkt. Bei einer losen Verschiebbarkeit kann beispielsweise vorgesehen sein, dass das Ausrichtmittel und/oder das Anschlagmittel in Bezug auf den Hilfskörper mittels Reibung in Position bleibt, insbesondere sodass für eine weitere Verschiebung die Reibung überwunden wird. Durch eine Verstellbarkeit kann die Relation zwischen dem Anschlagmittel und dem Ausrichtmittel veränderbar sein, sodass entsprechend auch die Relation der Wickelhülse zur Referenz veränderbar ist. So ist es beispielsweise denkbar, dass eine Folgehülse kürzer ist als die zweite, insbesondere im Produktionsprozess befindliche, Wickelhülse und der Bediener einen Soll-Abstand der Stirnseite der Folgehülse zur Referenz, insbesondere zur Stirnseite der zweiten Wickelhülse, auf einer zweiten Hülsenaufnahme der Wickelmaschine kennt. Insbesondere kann der Bediener dadurch das Ausrichtmittel und das Anschlagmittel zueinander verstellen, sodass weiterhin in einem einfachen Prozess der Zusammenhang zwischen der Position des Ausrichtmittels und der Referenz erhalten bleibt, dies jedoch zu einem veränderten Zusammenhang zwischen der Wickelhülse und der Referenz führt. Um die Verstellbarkeit zu gewährleisten kann ferner vorteilhafterweise der Hilfskörper zweiteilig ausgestaltet sein, wobei insbesondere der erste und der zweite Teilkörper des Hilfskörpers gegeneinander verschiebbar sein können.Advantageously, in an auxiliary device according to the invention, the channel element may have a channel axis, and the stop means and / or the alignment means may be adjustable parallel to the channel axis. Under the channel axis can be understood an extension axis of the channel element, which is preferably aligned parallel to the cylinder axis or sleeve axis of the winding tube, when the auxiliary device on the winding tube is positioned to align the winding tube. Under an adjustability can be understood that the stop means and / or the alignment means, for example, is loosely displaceable or displaceable by a drive. Such a drive may be, for example, a spindle drive, which is driven by hand or driven by an energy unit. In the case of loose displaceability, provision can be made, for example, for the alignment means and / or the stop means to remain in position in relation to the auxiliary body by means of friction, in particular so that the friction is overcome for a further displacement. By an adjustability, the relation between the stop means and the alignment means can be changed, so that correspondingly also the relation of the winding tube to the reference is variable. So it is conceivable, for example, that a follower sleeve is shorter than the second, especially in the production process, winding tube and the operator has a desired distance of the end side of the follower sleeve for reference, in particular to the end face of the second winding tube on a second sleeve receptacle of the winding machine knows. In particular, the operator can thereby adjust the alignment means and the abutment means to one another, so that in a simple process, the relationship between the position of the alignment and the reference is maintained, but this leads to a changed relationship between the winding tube and the reference. In order to ensure the adjustability, the auxiliary body can also advantageously be designed in two parts, in which case in particular the first and the second partial body of the auxiliary body can be displaceable relative to one another.
Bei einer erfindungsgemäßen Hilfsvorrichtung kann ferner vorteilhafterweise vorgesehen sein, dass der Hilfskörper ein Griffmittel aufweist, insbesondere wobei das Griffmittel eine Vertiefung im Hilfskörper umfasst. Vorzugsweise kann vorgesehen sein, dass das Hilfsmittel zwei Vertiefungen umfasst, die an einander gegenüberliegenden Seiten des Hilfskörpers angeordnet sind. Unter einem Griffmittel kann jedoch auch ein Handgriff oder eine Erhöhung verstanden werden. Eine Vertiefung kann beispielsweise eine abgerundete Nut sein, welche vorzugsweise an die Form eines Teils einer Hand oder eines Fingers zum Eingreifen angepasst sein kann. Dadurch kann die Ergonomie bei der Bedienung der Hilfsvorrichtung sowie die sichere Handhabung derselben weiter gesteigert sein, sodass die Fallgefahr der Hilfsvorrichtung verringert ist und damit ein robuster Einsatz verbessert ist. Zwei Vertiefungen an gegenüberliegenden Seiten des Hilfskörpers bieten ferner den Vorteil, dass die Hilfsvorrichtung dadurch ergonomisch umgreifbar ist, während gleichzeitig eine Unterstützung von Daumen und Fingern gegeben sein kann.In an auxiliary device according to the invention may also be advantageously provided that the auxiliary body has a handle means, in particular wherein the handle means comprises a recess in the auxiliary body. Preferably, it can be provided that the aid comprises two recesses which are arranged on opposite sides of the auxiliary body. However, a grip means can also be understood to mean a handle or an elevation. A recess may for example be a rounded groove, which may preferably be adapted to the shape of a part of a hand or a finger for engagement. As a result, the ergonomics in the operation of the auxiliary device and the safe handling of the same can be further increased, so that the risk of falling of the auxiliary device is reduced and thus a robust use is improved. Two recesses on opposite sides of the auxiliary body also offer the advantage that The auxiliary device is ergonomically umgreifbar thereby, while at the same time can be given support of thumb and fingers.
Es ist des Weiteren denkbar, dass eine erfindungsgemäße Hilfsvorrichtung eine Energieeinheit aufweist, um das Ausrichtmittel zu betreiben, insbesondere wobei die Energieeinheit eine Batterie ist. Alternativ kann unter der Energieeinheit jedoch auch eine Solarzelle oder eine andere Energiequelle verstanden werden. Dadurch kann Energie zur Verfügung gestellt werden, welche beispielsweise zum Betrieb eines Lasers oder für eine oder mehrere weitere Automatisierungsfunktionen der Hilfsvorrichtung einsetzbar ist. Durch den Einsatz der Energieeinheit kann dabei ferner die Mobilität und damit die Flexibilität der Hilfsvorrichtung weiter gesteigert sein, da beispielsweise keine Energieverbindung wie ein Kabel oder dergleichen notwendig ist. Vorzugsweise kann die Batterie eine Lithium-Ionen-Batterie sein, um eine hohe Zuverlässigkeit und Haltbarkeit der Batterie zu gewährleisten.It is also conceivable that an auxiliary device according to the invention has a power unit to operate the alignment, in particular wherein the energy unit is a battery. Alternatively, however, the energy unit can also be understood as meaning a solar cell or another energy source. As a result, energy can be made available, which can be used, for example, for operating a laser or for one or more further automation functions of the auxiliary device. The use of the energy unit can further increase the mobility and thus the flexibility of the auxiliary device, since, for example, no energy connection such as a cable or the like is necessary. Preferably, the battery may be a lithium-ion battery to ensure high reliability and durability of the battery.
Vorteilhafterweise kann der Hilfskörper bei einer erfindungsgemäßen Hilfsvorrichtung zumindest eine erste Auflagefläche umfassen, die mit der Wickelhülse in Anlage bringbar ist. Zusätzlich oder alternativ kann die Auflagefläche auch mit der Hülsenaufnahme in Anlage bringbar sein, z.B. wenn eine Anschlagfläche des Anschlagmittels durch eine Stirnfläche des Hilfskörpers gebildet ist. Vorzugsweise kann die Auflagefläche strukturiert sein. Durch die Struktur kann an der Auflagefläche ein erhöhter Reibwert erzielt werden. Dadurch kann ein Aufsetzen der Hilfsvorrichtung auf der Wickelhülse vereinfacht sein, insbesondere wobei die Auflagefläche gleichzeitig eine Sicherheit gegen Herunterfallen gewährleisten kann. Auch kann, beispielsweise wenn es sich bei der Wickelhülse um eine Hülse aus Pappe handelt, ein Eindringen der Struktur der Auflagefläche vorgesehen sein, sodass der Halt der Hilfsvorrichtung auf der Wickelhülse unterstützt wird.Advantageously, in the case of an auxiliary device according to the invention, the auxiliary body may comprise at least one first bearing surface which can be brought into contact with the winding sleeve. Additionally or alternatively, the support surface can also be brought into contact with the sleeve receptacle, e.g. when a stop surface of the stop means is formed by an end face of the auxiliary body. Preferably, the support surface may be structured. Due to the structure, an increased coefficient of friction can be achieved on the support surface. Thereby, a placement of the auxiliary device on the winding tube can be simplified, in particular wherein the bearing surface can simultaneously ensure safety against falling. Also, for example, if the winding tube is a cardboard sleeve, penetration of the structure of the bearing surface may be provided so that the support of the auxiliary device is supported on the winding tube.
Im Rahmen der Erfindung kann der Hilfskörper zumindest eine zweite Auflagefläche umfassen, die in einem Winkel zu der ersten Auflagefläche angeordnet ist. Insbesondere kann der Winkel kleiner oder gleich 150°, bevorzugt kleiner oder gleich 135°, sein. Dadurch können die Auflageflächen eine prismatische Form erzeugen, sodass unterschiedliche Durchmesser von Wickelhülsen berücksichtigbar sind. Vorzugsweise kann ferner vorgesehen sein, dass die Auflageflächen durch eine Vertiefung getrennt sind, die insbesondere mittig des Hilfskörpers verläuft. Dies kann vorteilhaft sein, um Wickelhülsen unterschiedlicher Radien durch die Auflageflächen aufzunehmen, da kleine Radien tiefer im Hilfskörper liegen. Außerdem kann die Kerbwirkung an der Stelle, an welcher die Auflageflächen aufeinander treffen, reduziert sein und insbesondere eine mögliche, fertigungsbedingte unsaubere Kante zwischen den Auflageflächen kann vermieden werden. Dabei ist jedoch insbesondere auch denkbar, dass beide Auflageflächen durch ein gebogenes, einzelnes Flächenelement realisiert sind. Durch die Anordnung der Auflageflächen kann insbesondere somit die Flexibilität der Hilfsvorrichtung gegenüber Wickelhülsen unterschiedlicher Durchmesser und gleichzeitig der Halt der Hilfsvorrichtung auf der Wickelhülse ebenfalls gesteigert sein.In the context of the invention, the auxiliary body may comprise at least a second bearing surface, which is arranged at an angle to the first bearing surface. In particular, the angle may be less than or equal to 150 °, preferably less than or equal to 135 °. Thereby, the bearing surfaces can produce a prismatic shape, so that different diameters of winding tubes are taken into account. Preferably, it may further be provided that the support surfaces are separated by a recess which extends in particular centrally of the auxiliary body. This can be beneficial to cores take different radii through the bearing surfaces, since small radii are deeper in the auxiliary body. In addition, the notch effect at the point at which meet the bearing surfaces to each other, be reduced and in particular a possible, production-related unclean edge between the bearing surfaces can be avoided. However, it is also conceivable that both bearing surfaces are realized by a curved, individual surface element. As a result of the arrangement of the support surfaces, the flexibility of the auxiliary device relative to winding tubes of different diameters and at the same time the support of the auxiliary device on the winding tube can thus also be increased in particular.
Es ist des Weiteren denkbar, dass bei einer erfindungsgemäßen Hilfsvorrichtung das Anschlagmittel eine Klinge umfasst, welche insbesondere eine Dicke kleiner oder gleich 1 mm, vorzugsweise kleiner oder gleich 0,6 mm, aufweist. Dabei kann die Klinge besonders dünn ausgestaltet sein und vorzugsweise einen geschärften Randbereich aufweisen. Ferner kann das Anschlagmittel beispielsweise als Blechelement, zum Beispiel aus Edelstahl, vorgesehen sein. Dies bietet den Vorteil, dass das Anschlagmittel dadurch besonders robust gegenüber Belastungen und widrigen Umweltbedingungen innerhalb eines Produktionsbetriebes ist. Wenn das Anschlagmittel eine Klinge umfasst, bietet dies ferner den Vorteil, dass die Klinge zwischen zwei Hülsenteile einfügbar ist und so das Anschlagmittel mit einer Stirnfläche des zu bewegenden Hülsenteils in Anlage bringbar ist, sodass dieses an der Referenz ausrichtbar ist.It is also conceivable that in an auxiliary device according to the invention, the stop means comprises a blade, which in particular has a thickness less than or equal to 1 mm, preferably less than or equal to 0.6 mm. In this case, the blade can be made particularly thin and preferably have a sharpened edge region. Furthermore, the stop means may be provided, for example, as a sheet metal element, for example made of stainless steel. This offers the advantage that the stop means is therefore particularly robust against loads and adverse environmental conditions within a production plant. If the stop means comprises a blade, this also has the advantage that the blade can be inserted between two sleeve parts and thus the stop means can be brought into contact with an end face of the sleeve part to be moved, so that it can be aligned at the reference.
Im Rahmen der Erfindung kann ferner vorgesehen sein, dass die Hilfsvorrichtung ein Schaltelement umfasst, durch welches das Ausrichtmittel von einem aktivierten Zustand in einen deaktivierten Zustand überführbar ist, wobei das Ausrichten der Wickelhülse an der Referenz über die Hilfsvorrichtung möglich ist, wenn sich das Ausrichtmittel im aktivierten Zustand befindet, und wobei das Ausrichten der Wickelhülse an der Referenz über die Hilfsvorrichtung unmöglich ist, wenn sich das Ausrichtmittel im deaktivierten Zustand befindet. Dabei kann das Schaltelement insbesondere vorteilhafterweise einer Peilrichtung des Ausrichtmittels am Hilfskörper gegenüberliegend angeordnet sein. Unter dem Schaltelement kann ein Bauteil oder eine Baugruppe verstanden werden, welche vorzugsweise durch einen Bediener betätigbar ist und elektrisch oder manuell zugänglich ist. Dabei kann das Schaltelement einen Taster umfassen, welcher von dem Bediener gedrückt werden kann, um zwischen dem aktivierten Zustand und dem deaktivierten Zustand zu wechseln. Das Schaltelement kann jedoch auch signalgesteuert sein, sodass dieses über eine Software die Zustandsänderung ermöglicht. Ferner kann vorgesehen sein, dass das Ausrichtmittel in einem deaktivierten Zustand geschützt oder ausgeschaltet ist und in einem aktiven Zustand sich in einer Betriebsposition befindet oder eingeschaltet ist. Unter der Peilrichtung kann insbesondere eine Zielrichtung des Ausrichtmittels verstanden werden, unter welcher die Referenz anvisiert werden kann bzw. kann unter der Zielrichtung die Wirkrichtung des Ausrichtmittels verstanden werden, in welcher insbesondere das Ausrichtmittel und die Referenz zueinander liegen. Durch das Schaltelement ergibt sich der Vorteil, dass das Ausrichtmittel schützbar ist bzw. durch einen zwischenzeitlichen deaktivierten Zustand Energie eingespart werden kann. Dadurch ergibt sich eine gesteigerte Robustheit der Hilfsvorrichtung. Zusätzlich kann sich der Vorteil ergeben, dass die Sicherheit der Hilfsvorrichtung durch das Vorsehen eines deaktivierten Zustandes des Ausrichtmittels erhöht ist, wenn es sich beispielsweise bei dem Ausrichtmittel um einen Laser handelt, welcher beim Hineinsehen das Augenlicht eines Bedieners beeinträchtigen kann. Durch eine Anordnung des Schaltelementes gegenüber der Peilrichtung des Ausrichtmittels kann ferner weiterhin die Ergonomie gesteigert sein, sodass dieses beispielsweise mit einem Daumen betätigbar ist. Dadurch kann das Ausrichten weiter vereinfacht sein.In the context of the invention, it can further be provided that the auxiliary device comprises a switching element, by which the alignment means can be converted from an activated state to a deactivated state, wherein the alignment of the winding tube at the reference via the auxiliary device is possible when the alignment means in activated state, and wherein the alignment of the winding tube at the reference via the auxiliary device is impossible when the alignment means is in the deactivated state. In this case, the switching element may in particular advantageously be arranged opposite a direction of boring of the alignment means on the auxiliary body. Under the switching element, a component or an assembly can be understood, which is preferably actuated by an operator and is electrically or manually accessible. In this case, the switching element may comprise a button which is pressed by the operator can be used to switch between the activated state and the deactivated state. However, the switching element can also be signal-controlled, so that this allows the state change via software. Furthermore, it can be provided that the alignment means is protected or switched off in a deactivated state and is in an active state in an operating position or is switched on. In particular, a direction of orientation of the alignment means, under which the reference can be targeted, or the target direction can be understood as meaning the effective direction of the alignment means, in which the alignment means and the reference lie in relation to one another. The advantage of the switching element is that the alignment means can be protected or energy can be saved by an intermediate deactivated state. This results in an increased robustness of the auxiliary device. In addition, the advantage may arise that the safety of the auxiliary device is increased by the provision of a deactivated state of the alignment means, for example if the alignment means is a laser which, when viewed, may impair the eyesight of an operator. Furthermore, by arranging the switching element in relation to the direction of orientation of the alignment means, the ergonomics can furthermore be increased, so that the latter can be actuated, for example, with a thumb. As a result, the alignment can be further simplified.
Im Rahmen der Erfindung kann weiter vorgesehen sein, dass der Hilfskörper aus einem Kunststoff ausgebildet ist. Ein derartiger Kunststoff kann beispielsweise Polyethylen, Polypropylen oder Polyvinylchlorid aufweisen. Besonders bevorzugt kann es sich bei dem Kunststoff um ein Polyamid handeln. Ferner kann der Kunststoff insbesondere glas- oder kohlefaserverstärkt sein. Dabei kann der Hilfskörper vorzugsweise als Gussteil oder als Frästeil sein. Somit kann der Hilfskörper günstig herstellbar sein und gleichzeitig eine Robustheit gegenüber Herunterfallen oder sonstigen Extremsituationen der Hilfsvorrichtung aufweisen. Weiterhin kann der Hilfskörper vorteilhafterweise einstückig mit dem Anschlagmittel ausgebildet sein, insbesondere so dass das Anschlagmittel ebenfalls aus Kunststoff ausgebildet ist. Der Hilfskörper und das Anschlagmittel können jedoch auch mehrteilig ausgebildet sein, wobei das Anschlagmittel vorzugsweise ein Metall oder einen harten Kunststoff aufweist und insbesondere der Hilfskörper aus Kunststoff ausgebildet ist.In the context of the invention may further be provided that the auxiliary body is formed of a plastic. Such a plastic may for example comprise polyethylene, polypropylene or polyvinyl chloride. Particularly preferably, the plastic may be a polyamide. Furthermore, the plastic may in particular be glass or carbon fiber reinforced. In this case, the auxiliary body may be preferably as a casting or as a milled part. Thus, the auxiliary body can be produced inexpensively and at the same time have a robustness against falling or other extreme situations of the auxiliary device. Furthermore, the auxiliary body may advantageously be formed integrally with the stop means, in particular so that the stop means is also formed of plastic. However, the auxiliary body and the stop means may also be designed in several parts, wherein the stop means preferably comprises a metal or a hard plastic and in particular the auxiliary body is formed of plastic.
Gemäß einem weiteren Aspekt der Erfindung ist ein Verfahren zum Ausrichten einer Wickelhülse an einer Referenz beansprucht. Dabei weist das Verfahren die folgenden Schritte auf:
- Platzieren einer Hilfsvorrichtung an der Wickelhülse, sodass ein Anschlagmittel der Hilfsvorrichtung mit einem Gegenanschlagmittel der Wickelhülse in Anlage gebracht ist,
- gemeinsames Verschieben der Hilfsvorrichtung und der Wickelhülse bis ein Ausrichten der Wickelhülse an der Referenz über ein Ausrichtmittel der Hilfsvorrichtung erfolgt.
- Placing an auxiliary device on the winding tube, so that a stop means of the auxiliary device is brought into abutment with a counter-stop means of the winding tube,
- common displacement of the auxiliary device and the winding tube until an alignment of the winding tube takes place at the reference via an alignment of the auxiliary device.
Dabei kann unter dem gemeinsamen Verschieben verstanden werden, dass die Hilfsvorrichtung beispielsweise auf die Wickelhülse aufgelegt oder auf dieser fixiert wird, wobei das Verschieben durch Schieben der Hilfsvorrichtung und/oder der Wickelhülse realisiert wird.It can be understood by the common displacement that the auxiliary device is placed for example on the winding tube or fixed on this, wherein the displacement is realized by sliding the auxiliary device and / or the winding tube.
Vorzugsweise kann ferner ein Vorbereitungsschritt vorgesehen sein, wobei die Wickelhülse auf eine Hülsenaufnahme einer Wickelmaschine aufgesteckt wird. Somit bietet auch das Verfahren eine besonders einfache, flexible und sichere Möglichkeit, das Ausrichten einer Wickelhülse vorzunehmen. Weiterhin kann vorteilhafterweise ein Nachbereitungsschritt vorgesehen sein, in welchem die Wickelhülse durch ein Spannmittel der Wickelhülse oder der Hülsenaufnahme in ihrer Position auf der Hülsenaufnahme fixiert wird. Vorzugsweise kann die Hilfsvorrichtung nach einem der Ansprüche 1 bis 13 ausgebildet sein. Damit bringt ein erfindungsgemäßes Verfahren die gleichen Vorteile mit sich wie sie ausführlich mit Bezug auf eine erfindungsgemäße Vorrichtung beschrieben worden sind.Preferably, further, a preparation step may be provided, wherein the winding tube is plugged onto a sleeve receptacle of a winding machine. Thus, the method offers a particularly simple, flexible and secure way to make the alignment of a winding tube. Furthermore, advantageously, a post-processing step may be provided, in which the winding tube is fixed by a clamping means of the winding tube or the sleeve receptacle in its position on the sleeve receptacle. Preferably, the auxiliary device may be formed according to one of
Im Rahmen der Erfindung kann ferner vorgesehen sein, dass das Verfahren zusätzlich folgenden, insbesondere vorbereitenden, Schritt aufweist:
- Überführen des Ausrichtmittels von einem deaktivierten Zustand in einen aktivierten Zustand.
- Transferring the alignment means from a deactivated state to an activated state.
Vorzugsweise kann das Überführen des Ausrichtmittels vor dem Ausrichten der Wickelhülse an der Referenz erfolgen. Durch das Vorsehen der unterschiedlichen Zustände kann ein Energiesparen erfolgen. Ferner kann die Sicherheit des Verfahrens zum Ausrichten der Wickelhülse verbessert sein, wenn der aktive Zustand des Ausrichtmittels ein Verletzungsrisiko, wie beispielsweise beim direkten Hineinblicken in eine Laserquelle durch den Bediener, darstellen kann.Preferably, the transfer of the alignment means can take place before the alignment of the winding tube at the reference. By providing the different states, energy can be saved. Furthermore, the safety of the method for aligning the Winding sleeve can be improved when the active state of the alignment means can pose a risk of injury, such as when looking directly into a laser source by the operator.
Die Schritte eines erfindungsgemäßen Verfahrens können vorzugsweise in der gegebenen Reihenfolge oder einer anderen Reihenfolge erfolgen. Insbesondere können einzelne Schritte oder alle Schritte des Verfahrens wiederholbar sein bzw. wiederholt werden.The steps of a method according to the invention may preferably be carried out in the given order or in a different order. In particular, individual steps or all steps of the method can be repeated or repeated.

In den nachfolgenden Figuren werden für die gleichen technischen Merkmale auch von unterschiedlichen Ausführungsbeispielen die identischen Bezugszeichen verwendet.In the following figures, the identical reference numerals are used for the same technical features of different embodiments.
Ferner kann vorteilhafterweise vorgesehen sein, dass das Ausrichtmittel 13 derart angeordnet ist, dass das Ausrichtmittel 13 und die Referenz 1 im Wesentlichen in einer parallelen oder identischen Ebene mit der Anschlagebene 20 liegen. Dadurch ergibt sich ein unmittelbarer Zusammenhang zwischen der axialen Positionierung des Gegenanschlagmittels 5, welches vorzugsweise eine Stirnseite der Wickelhülse 2 sein kann, und der Referenz 1. Die Referenz 1 kann insbesondere das zum Gegenanschlagmittel 5 korrespondierende Ende einer zweiten, insbesondere sich im Wickelprozess befindlichen, Wickelhülse 2.1 auf einer zugeordneten zweiten Hülsenaufnahme 3.1 sein. Die zweite Wickelhülse 2.1 kann beispielsweise durch einen Produktwickel 7, welcher insbesondere ein Folienwickel ist, umwickelt werden oder umwickelt sein, welcher über eine Kontaktwalze 6 der Wickelmaschine 4 angedrückt wird, um einen möglichst kompakten Produktwickel 7 zu erzeugen und/oder Lufteinschlüsse zu vermeiden. Damit die Wickelhülse 2 über die Hilfsvorrichtung 10 an der Referenz 1 ausrichtbar ist, befindet sich das Ausrichtmittel 13 in einem aktivierten Zustand I, sodass dieses in einer Peilrichtung 13.2 wirkt und ein Benutzer die relative Position der Wickelhülse 2 zu der Referenz 1 bzw. der zweiten Wickelhülse 2.1 abschätzen oder bestimmen kann. Vorzugsweise kann es sich bei dem Ausrichtmittel 13 um ein optisches Ausrichtmittel handeln, welches einen Bediener die Referenz 1 in Peilrichtung 13.2 anvisieren lässt oder in Peilrichtung 13.2 abstrahlt, so dass beispielsweise eine Lichtmarkierung entsteht. Ist der Wickelprozess des Produktwickels 7 um die zweite Wickelhülse 2.1 abgeschlossen und die Wickelhülse 2 bestimmungsgemäß ausgerichtet, kann die Hilfsvorrichtung 10, welche insbesondere mobil ist, von der Wickelhülse 2 abgenommen werden, sodass die zweite Wickelhülse 2.1 und die Wickelhülse 2 mittels einer Drehvorrichtung 8 der Wickelmaschine 4 in ihren Positionen vertauscht werden. Dadurch kann die zweite Wickelhülse 2.1 mit einem fertigen Produktwickel abgenommen werden und die neue Wickelhülse 2 umwickelt werden. Vorteilhafterweise kann die Wickelhülse 2 durch eine Spannvorrichtung der Wickelhülse 2 und/oder der Hülsenaufnahme 3 in ausgerichteter Position fixierbar sein, so dass die Wickelhülse 2 auch während des Wickelprozesses in der Wickelmaschine 4 nicht auf der Hülsenaufnahme 3 verrutscht.Furthermore, it can advantageously be provided that the alignment means 13 is arranged such that the alignment means 13 and the
