Furthermore, the present invention comprises a method (100) for aligning a winding tube (2) on a reference (1).

Description

The present invention relates to an auxiliary device for aligning a winding tube and a method for aligning a winding tube.

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.

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.

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.

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.

The above object is achieved by a device having the features of claim 1 and a method having the features of claim 14.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

• gemeinsames Verschieben der Hilfsvorrichtung und der Wickelhülse bis ein Ausrichten der Wickelhülse an der Referenz über ein Ausrichtmittel der Hilfsvorrichtung erfolgt.

According to another aspect of the invention, a method of aligning a winding tube to a reference is claimed. The method has the following steps:

• 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.

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.

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 claims 1 to 13. Thus, a method according to the invention entails the same advantages as have been described in detail with reference to a device according to the invention.

In the context of the invention, it can further be provided that the method additionally has the following, in particular preparatory, step:

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.

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 the following figures, the identical reference numerals are used for the same technical features of different embodiments.

Fig. 1 shows an auxiliary device 10 according to the invention in a schematic side view of a winding machine 4 for aligning a winding tube 2 on a sleeve receptacle 3 of the winding machine 4 at a reference 1 in a first embodiment. In this case, the auxiliary device 10 is arranged on the winding tube 2, so that a stop means 12 of an auxiliary body 11 of the auxiliary device 10 with a counter-stop means 5 of the winding tube 2 is brought into abutment, in particular a stop surface 12.1 of the stop means 12 and a counter stop surface 5.1 of the counter-stop means 5 interact , The counter-stop means 5 may preferably be an end face of the winding tube 2. The stop means 12 may further comprise a blade 12.2 which extends in the direction of a cylinder axis of the winding tube 2 from the auxiliary body 11. For aligning the winding tube 2 at the reference 1, the auxiliary device 10 further comprises an alignment means 13, wherein the alignment means 13 and the stop means 12 have a determinable relation to each other. In this case, the stop means 12 on the counter-stop means 5 at least substantially or completely in a contact plane 20 can be applied.

Furthermore, it can advantageously be provided that the alignment means 13 is arranged such that the alignment means 13 and the reference 1 lie substantially in a parallel or identical plane with the stop plane 20. This results in a Direct reference between the axial positioning of the counter-stop means 5, which may preferably be an end face of the winding tube 2, and the reference 1. The reference 1 may in particular the end of a second, in particular located in the winding process, the winding sleeve 2.1 corresponding to the counter-stop means 5 on an associated be second sleeve receptacle 3.1. The second winding tube 2.1, for example, by a product roll 7, which is in particular a film roll to be wound or wrapped, which is pressed over a contact roller 6 of the winding machine 4, to produce a compact product as possible winding 7 and / or to avoid air pockets. In order for the winding tube 2 to be alignable via the auxiliary device 10 at the reference 1, the alignment means 13 is in an activated state I, so that this acts in a direction of bores 13.2 and a user the relative position of the winding tube 2 to the reference 1 and the second Can estimate or determine winding tube 2.1. The alignment means 13 may preferably be an optical alignment means which allows an operator to sight the reference 1 in the direction of the boring 13.2 or emit in the boresight direction 13.2 so that, for example, a light marking is formed. If the winding process of the product roll 7 is completed about the second winding tube 2.1 and the winding tube 2 aligned as intended, the auxiliary device 10, which is particularly mobile, can be removed from the winding tube 2, so that the second winding tube 2.1 and the winding tube 2 by means of a rotating device 8 of Winding machine 4 are reversed in their positions. As a result, the second winding tube 2.1 can be removed with a finished product wrap and the new winding tube 2 are wrapped. Advantageously, the winding tube 2 can be fixed by a clamping device of the winding tube 2 and / or the sleeve receptacle 3 in the aligned position, so that the winding tube 2 does not slip on the sleeve receptacle 3 during the winding process in the winding machine 4.

Fig. 2 shows the auxiliary device 10 according to the invention according to the first embodiment in a schematic side view of the winding machine 4 in the winding machine 4, seen from the side, which the view of FIG. 1 opposite. It is clear that the auxiliary device 10 is arranged with a downwardly open channel element 14 of the auxiliary body 11 on the winding tube 2, so that in conjunction with the in Fig.1 shown stop means 12, which is brought to the counter-stop means 5 for conditioning, and the auxiliary device 10 only a rotational degree of freedom on the Winding tube 2 remains. The alignment means 13 may therefore preferably be a line-shaped laser, so that the rotational positioning of the auxiliary device 10 on the winding tube 2 also permits large tolerances without loss of accuracy. This simplifies the alignment of the winding tube 2 with reference to the reference 1.

Fig. 3 shows the auxiliary device 10 according to the invention for aligning the winding tube 2 on a sleeve receptacle 3 of the winding machine 4 according to the first embodiment in plan view. It is clear that the alignment of the winding tube 2 by means of the auxiliary device 10 is carried out axially until the alignment 13 is aligned with the reference 1. This can ensure that a connection between the positioning of the winding tube 2 and the second winding tube 2.1 is ensured. Therefore, it is particularly advantageous if the alignment means 13 is arranged such that the alignment means 13 and the reference 1 are at least substantially in an identical plane with the stop plane 20 when the winding tube is aligned. For this purpose, the stop means 12 preferably has a stop surface 12.1 and the counter stop means 5 preferably a counter stop surface 5.1. However, other embodiments are also conceivable here, such as a parallel plane.

The auxiliary device 10 of the first embodiment may additionally or alternatively also according to the FIGS. 5 to 6 , Preferably according to the auxiliary devices of the embodiments of FIGS. 4 or 7 be educated.

Fig. 4 shows an auxiliary device 10 according to the invention in a schematic side view in a further embodiment. In this case, the auxiliary device 10 has an auxiliary body 11 with a first part body 11.1 and a second part body 11.2. Furthermore, a stop means 12, which comprises a blade 12.2, arranged on the second part body 11.2 of the auxiliary body 11. On the first part of the body 11.1 of the auxiliary body 11, an alignment means 13 is further arranged, which is suitable for aligning the winding tube 2 to a reference 1, as shown for example in the first embodiment. In this case, the stop means 12 and the alignment 13 have a determinable relation to each other, which may be in the present embodiment, for example, the distance from the center of the alignment 13 to a stop plane 20 of the stop means 12 on the counter-stop means 5 of the winding tube 2. Preferably, the auxiliary device 10 may be formed such that the stop means 12 is adjustable to the alignment 13. As a result, a changed relation between stop means 12 and alignment means 13 can be generated. Advantageously, for example, the first and the second body part 11.1, 11.2 be mutually adjustable, this adjustment can be carried out in particular along a channel axis 14.1 of a channel element 14 open on one side. Furthermore, the stop means 12 comprises a blade 12.2, so that the blade 12.2 can also be inserted between two winding sleeves 2, for example in order to separate them or to align a single winding sleeve. In addition, a handle 15 is provided on the auxiliary body 11. The gripping means 15 can preferably be introduced through a groove which is inserted into the auxiliary body 11. Furthermore, a securing element 19 is provided on the auxiliary body 11. In particular, the securing element 19 is a key ring which can be connected to a flexible securing means of a winding machine 4 in order to protect the auxiliary device 10 against falling. The flexible securing means of the winding machine 4 may be for example a rope, a wire or the like.

Fig. 5 shows an auxiliary device 10 according to the invention in a schematic front view of the auxiliary device 10 in a further embodiment. In this case, the auxiliary device 10 on an auxiliary body 11, wherein on two opposite sides of the auxiliary body 11 each have a handle means 15 is attached. In this case, the gripping means 15 is preferably formed as a groove. As a result, an operator can grasp the auxiliary device 10 from above while engaging in the gripping means 15. Furthermore, the auxiliary device 10 has a channel element 14, which is formed in particular by two downwardly projecting parts of the auxiliary body 11. In this case, a channel axis 14.1 runs along the main extension direction of the auxiliary body 11, in particular perpendicular to the plane of the drawing. Further, a first and a second bearing surface 18 are formed on the auxiliary body 11, which are aligned at an angle 18.1 to each other. Preferably, the angle 18.1 may be less than or equal to 150 °, more preferably less than or equal to 135 °. The bearing surfaces 18 are designed to be brought into contact with a winding tube 2. In order to ensure an improved grip in this regard, it may further be provided that the bearing surfaces 18 are structured. For example, a knurling of the support surfaces 18 or a knob-like structure may be provided to increase the coefficient of friction. Between the support surfaces 18, a groove 18.2 is further provided, so that the notch effect is reduced at this point and different diameters of cores 2 can be considered in particular.

Fig. 6 shows an auxiliary device 10 according to the invention with an auxiliary body 11, which in each case comprises a gripping means 15 on two opposite sides. For this purpose, a channel element 14 is further formed, which is open at the bottom. Further, bearing surfaces 18 are formed on the underside of the auxiliary body 11, so that the auxiliary device 10 can be placed with the bearing surfaces 18 on a winding tube 2. By an angle 18.1 between the support surfaces 18 and a groove 18.2, which runs centrally between the support surfaces 18, different diameters of different winding tubes 2 are advantageously considered. In this case, the auxiliary device 10 may alternatively be placed on a sleeve receptacle 3 via the bearing surfaces 18, so that one end face of the auxiliary body 11 can serve as a stop means 12. Additionally or alternatively, the stop means 12 may be provided in particular but also as an additional component which is attached to a portion of the auxiliary body 11. Further, as seen in the partial fracture view, in the auxiliary body 11, a light module 13.1 of an alignment means 13 is arranged. This can advantageously be inserted through an opening in a bore of the auxiliary body 11, so that the assembly of the auxiliary device 10 is inexpensive. Further, in addition to the alignment means 13, a switching element 17 is arranged, which is adapted to switch between an activated I and a deactivated state II (shown here) of the alignment means 13. Thereby, the total energy consumption of the alignment means 13 can be lowered and thus the mobility of the auxiliary device 10 can be increased. The safety during alignment can also be increased by the switching element 17, in particular so that possible sources of danger, which can start from an activated state of the alignment means 13, are reduced. The switching element 17 is particularly in the context of embodiments of the FIGS. 1 to 5 and 7 to 8 used.

Fig. 7 shows an auxiliary device 10 according to the invention in a further embodiment in a perspective view. In this case, the auxiliary device 10 comprises an auxiliary body 11, which has on two opposite sides a gripping means 15, wherein the gripping means 15 is in particular formed in each case as a groove. However, other forms of grip means, such as an additional component, are also conceivable here. Further points the auxiliary device 10 an alignment means 13, which is in determinable relation to a stop means 12. In this case, the state shown is a deactivated state II of the alignment means 13, wherein this example, by a switch unit 17, such as in Fig. 6 represented, in an activated state I can be transferred. The stop means 12 further comprises a blade 12.2, which protrudes from the auxiliary body 11 via bearing surfaces 18 for placing the auxiliary device 10 on a winding tube 2 and thereby provides a stop plane 20. The bearing surfaces 18 thereby form a channel element 14 which is open to one side, wherein a groove 18.2 is provided between the bearing surfaces 18. Furthermore, the auxiliary body 11 has a functional compartment 16.1. In this case, the functional compartment 16.1 may be provided as an opening, through which a power unit 16 can be introduced into the auxiliary body 11. The energy unit 16 can preferably be a battery, particularly preferably a lithium-ion battery, via which energy for the alignment means 13 and / or an adjustability of the stop means 12 can be provided. As a result, for example, a laser of the alignment means 13 can be operated independently of an external power source. This increases the mobility of the auxiliary device 10. Thus, it can further be provided that the auxiliary device 10 is a hand-held device which can be operated independently of a winding machine 4. As a result, an auxiliary device 10 can be used, for example, for a plurality of winding machines 4. In particular, the auxiliary body 11 may further be formed of a plastic, preferably a polyamide. In this case, the stop means 12 may be provided integrally with the auxiliary body 11 or attached thereto. In a multi-part embodiment, the stop means 12 may further preferably be formed of a stainless steel. Furthermore, in particular the energy unit 16 and / or the functional compartment 16.1 are also advantageously in the context of the first embodiment and in the context of the embodiments of FIGS. 4 . 5 . 6 and 8th used.

Fig. 8 shows a method according to the invention for aligning a winding tube 2 to a reference 1 in a schematic representation. In this case, placing 102 an auxiliary device 10 is provided on the winding tube 2, so that a stop means 12 of the auxiliary device 10 is brought into abutment with a counter-stop means 5 of the winding tube 2. Subsequently, a common displacement 103 of the auxiliary device 10 and the winding tube 2 follows until an alignment of the winding tube 2 and the reference 1 via an alignment 13 of the auxiliary device 10 takes place. Further, preferably, a transfer 101 of the alignment means 13 of a deactivated state II in an activated state I, in particular before placing 102 of the auxiliary device 10, take place. In this case, individual steps of the method 100 can be repeated as often as desired, and the entire method 100 can also be repeated in order, for example, to align a plurality of winding cores. The method 100 thus offers a flexible, simple possibility by means of the auxiliary device 10 to align the winding tube 2 at the reference 1.

The above explanation of the embodiments describes the present invention solely by way of example. Of course, individual features of the embodiments, if technically feasible, can be combined freely with one another, without departing from the scope of the present invention.
