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 tube, since it is, for example, a product with a wide but flat extension, such tubes are regularly replaced. Such an exchange can take place, for example, because a previously wrapped sleeve is wrapped with a certain amount of the product, or else if a partially finished wrap, comprising the product and the sleeve, is sorted out as rejects. This can be provided, for example, due to the product being torn off. An example of a production process is the film production, in which a sleeve is wrapped with film until one given product scope is given. For the exchange, a second winding tube is placed on a separate tube holder, so that it can be replaced automatically or manually, for example by rotating a machine part, which comprises the preparatory and the holder in operation. However, since different widths of the product are also produced in such a winding machine, a tube holder is often made wider than a tube to be taken up, so that for the exchange between the preparatory tube and the tube being produced, both tubes are aligned with one another, so that the following one Product defined is arranged on the sleeve.

For example, it may be necessary for the product to be wound onto the core in the middle, so that a portion of the core protrudes from the ends of the core and the core can be picked up in a later process step. In order to be able to carry out such an alignment, the end points of the old sleeve are often marked when the previous sleeve is removed on a sleeve holder, which is possible, for example, manually by inserting a notch on the sleeve holder. However, this manual process is complex since new markings are necessary, which, if they are not removed, additionally promote a confusion, since the assignment of the last, "correct" notch becomes more difficult as the number increases. The operator may also climb into the machine to find a reference point. However, this is cumbersome since there is often little space in such a production machine.

Rigid devices are also known which are attached to a fixed position in a winding machine, so that a specific orientation of a winding tube can be approached for each device. However, such devices are inflexible, particularly with regard to changing product sizes or different winding cores. For example, each of the rigid devices can often only be used on the machine for a single winding tube size, since the fixed position cannot be changed.
The WO 01/42736 A1 and EP 1 310 447 A2 disclose an auxiliary device according to the preamble of claim 1.

It is an object of the present invention to at least partially overcome the above disadvantages known from the prior art. In particular, it is the job of Present invention to simplify alignment of a winding tube and thereby ensure the alignment of the winding tube safely and flexibly at low cost.

The above object is achieved by a device with the features of claim 1 and a method with the features of claim 13.

Further features and details of the invention emerge from the subclaims, the description and the drawings. 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 vice versa, so that with respect to the disclosure of the individual aspects of the invention, reference can always be made to one another.

According to the invention, an auxiliary device for aligning a winding tube with a reference comprises an auxiliary body with a stop means, which is designed to bear against a counter-stop means of the winding tube. The auxiliary device also includes an alignment means which is suitable for aligning the winding tube with the reference. The sling means and the alignment means also have a determinable relation to one another. In particular, the auxiliary device can be suitable for aligning a winding tube on a tube holder of a winding machine. The winding machine is preferably a winding machine for film production.

Thus, the winding tube is preferably a tube on which a film can be wound, so that it can be transported and / or resold. Furthermore, the winding tube can be understood to be a tube that is only suitable for receiving a product roll or a tube that forms the basis for a product roll with other tubes. A stop means or a counter stop means can preferably be understood to mean a flat design of the auxiliary body or the winding tube. For example, a shoulder in the form of the auxiliary body or a shoulder on the auxiliary body can be provided as the stop means, which can be brought into contact with an end face of the winding tube and can thus act. However, other forms of counter-stop means and stop means are also conceivable, such as a round shape, preferably the stop means and the counter-stop means can be designed to correspond to each other. In particular, the shape of the attachment means can correspond to a negative shape of the counter-attachment means. Furthermore, the stop means can also comprise an additional component which is arranged directly or indirectly on a fastening section 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 tube relative to the reference with respect to at least one direction. The alignment means can thus be, for example, a direction finding means with which the operator can sight the reference. As a result, the operator can, for example, receive information about the current positioning of the auxiliary device or the winding tube relative to the reference. However, further forms of the alignment means are also conceivable, such as a rod, in particular a telescopic rod, which extends from the auxiliary device into the winding machine and can thus be brought close to the reference or in contact with the reference. The reference can be a specific point, a specific location or a specific area. The reference can preferably be the end of a second winding tube, in particular in production operation, or a position at a specific distance from the end of the second winding tube. Thus, the alignment of the winding tube can include moving the winding tube, in particular together with the auxiliary device, until the reference can be targeted by the alignment means. It is therefore also important for the alignment of the winding tube that the relationship between the lifting means and the alignment means can be determined. Such a determinable relation can be understood to mean, for example, a dimensional relation, which is particularly measurable. However, further determinable relations are also conceivable, for example the relation can be determined by reading a scale, which is preferably attached to the auxiliary body, or the relation can be determined electronically. However, other options for determining the relation are also conceivable here. An auxiliary body can preferably be understood to mean a main body of the auxiliary device, which in particular at least essentially determines the shape of the auxiliary device. For example, it can comprise a one-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 tube holder against displacement. For example, a tensioning device can be provided in the winding tube or in the tube receptacle in order to Securing especially after successful alignment of the winding tube, to ensure and thus secure for the further production process at the aligned point on the tube holder.

An auxiliary device according to the invention is thus easy to handle and can be used for different winding cores and thus also different references, so that flexible use in the production process, in particular of foils, can be made possible. In this case, the auxiliary device in particular enables the winding tube to be aligned during operation, so that, for example, the completion of a winding in operation of a second winding tube can still be in the process while the winding tube is being aligned. Thus, the production time in the manufacturing process can be shortened. The fact that the winding sleeve can advantageously be aligned at a distance from the reference can further increase the safety of the winding machine.

Within the scope of the invention it can also be advantageously provided that the alignment means is an optical and / or acoustic alignment means. An optical alignment means can be understood to mean, for example, an illuminant which emits light, so that the position of the alignment means can be compared with the reference. However, it is also 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 move the winding tube until the reference is aimed or is visible in a specific area of the lens. An acoustic alignment means can furthermore be understood to mean, for example, that a signal tone sounds as soon as the alignment means has reached a specific position in relation to the reference. For example, an optical alignment device could be combined with an acoustic alignment device, so that when the reference is reached, a light sensor emits a signal to an electronic device of the auxiliary device or the alignment device and the alignment device then generates the signal tone. Optical and / or acoustic alignment means have the particular advantage that they can work without contact. This enables a long range of the alignment means to be achieved, so that the alignment of the winding tube can take place at a distance from the production process. This allows the Security, comfort and flexibility in aligning the winding tube must 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. The positioning of the alignment means and thus the sling means or the winding tube can be shown to an operator by the light emitting module. A laser can advantageously have a high intensity of light emission, so that a visible and reliable alignment aid is still guaranteed even under different lighting conditions. In particular, a sharp delimitation of the laser or the area irradiated by the laser can also give high accuracy during alignment. The laser can advantageously be a cross-shaped or point-shaped laser. However, the light-emitting module, in particular the laser, preferably emits a linear region, so that exact positioning of the auxiliary device, in particular on the circumference of the winding tube, is not necessary, so that alignment can be further simplified if the stop means is brought into contact with the counter-stop means is.

According to the invention, the stop means can be placed on the counter stop means at least essentially in a stop plane and the aligning means is arranged such that the aligning means and the reference lie at least substantially in a parallel or identical plane with the stop plane when the winding tube is aligned. In particular, the alignment means and the reference can also lie completely in a parallel or identical plane with the stop plane when the winding tube is aligned. As a result, the reference can preferably be aimed at in the plane, so that the relationship between the alignment means and the stop means can be determined particularly easily and the alignment as a whole can be simplified.

In the context of the invention, the auxiliary device for aligning the winding tube can also advantageously be used in a mobile manner. In particular, a securing element can be provided, by means of which the auxiliary body can be secured on a winding machine. Under A mobile usability can be understood here that the auxiliary device is portable or transportable and thus can be separated in particular from the winding machine or can be used independently of the winding machine. Thus, the auxiliary device can preferably be a hand-held device. As a result, the auxiliary device can be used particularly flexibly and can be handled particularly easily, for example when used in different machines. A possible replacement of the auxiliary device can also be particularly simple. By means of the securing element, the auxiliary device can be fastened to the winding machine or can be connected to it. For example, a key ring or a simple through hole can be provided as a securing element. As a result, the auxiliary device can be attached to the winding machine, in particular detachably, by means of an additional securing means, for example a rope, a wire or the like, so that securing against falling or being lost while maintaining flexibility can be ensured.

An auxiliary device according to the invention can also preferably have a channel element which is suitable for receiving the winding tube. Such a channel element can be open on one side and thus be formed, for example, by a recess in the auxiliary body, webs projecting therefrom, additional walls or the like. This can ensure that the auxiliary device is placed on the winding tube and thus particularly easy to bring the stop means and the counter stop means into contact. Furthermore, this can make it possible for the auxiliary device to have only a rotational degree of freedom with respect to the winding tube when the channel element is correctly positioned, when the channel element is placed on the winding tube and the stop on the counter-stop of the winding tube. Due to the simple relation of the auxiliary device or the winding tube to the reference, the alignment of the winding tube can be further simplified.

In an auxiliary device according to the invention, the channel element can advantageously have a channel axis, and the stop means and / or the alignment means can be adjustable parallel to the channel axis. The channel axis can be understood to mean 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 is on the winding tube is positioned to align the winding tube. An adjustability can be understood to mean that the stop means and / or the alignment means can, for example, be moved loosely or can be moved by a drive. Such a drive can be, for example, a spindle drive which works by hand or driven by an energy unit. In the case of a loose displaceability, it can be provided, for example, that the alignment means and / or the stop means remains in position with respect to the auxiliary body by means of friction, in particular so that the friction is overcome for a further displacement. The relationship between the stop means and the alignment means can be changed by an adjustability, so that the relationship of the winding tube to the reference can also be changed accordingly. It is conceivable, for example, that a follower sleeve is shorter than the second, in particular in the production process, the winding sleeve and the operator knows a target distance of the end face of the follower sleeve from the reference, in particular to the end face of the second wrapping sleeve, on a second sleeve holder of the winding machine. In particular, the operator can thereby adjust the alignment means and the stop means to one another, so that the relationship between the position of the alignment means and the reference is maintained in a simple process, 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 configured in two parts, in particular the first and the second partial body of the auxiliary body being able to be displaced relative to one another.

In the case of an auxiliary device according to the invention, provision can furthermore advantageously be made for the auxiliary body to have a grip means, in particular wherein the grip means comprises a recess in the auxiliary body. It can preferably be provided that the aid comprises two depressions which are arranged on opposite sides of the auxiliary body. However, a grip means can also be understood to mean a handle or an increase. A depression can be, for example, a rounded groove, which can preferably be adapted to the shape of a part of a hand or a finger for engaging. As a result, the ergonomics in the operation of the auxiliary device and the safe handling thereof can be further increased, so that the risk of falling of the auxiliary device is reduced and thus a more robust use is improved. Two depressions on opposite sides of the auxiliary body also offer the advantage that the auxiliary device can thus be gripped ergonomically, while at the same time there can be support for the thumb and fingers.

It is furthermore conceivable that an auxiliary device according to the invention has a power unit in order to operate the alignment means, in particular wherein the power unit is a battery. Alternatively, the energy unit can also be understood to mean a solar cell or another energy source. As a result, energy can be made available, which can be used, for example, to operate a laser or for one or more further automation functions of the auxiliary device. Through the use of the energy unit, the mobility and thus the flexibility of the auxiliary device can further be increased, since for example no energy connection such as a cable or the like is necessary. The battery can preferably be a lithium-ion battery in order to ensure high reliability and durability of the battery.

In the case of an auxiliary device according to the invention, the auxiliary body can advantageously comprise at least one first contact surface which can be brought into contact with the winding tube. Additionally or alternatively, the contact surface can also be brought into contact with the sleeve receptacle, e.g. if a stop surface of the stop means is formed by an end face of the auxiliary body. The bearing surface can preferably be structured. Due to the structure, an increased coefficient of friction can be achieved on the contact surface. As a result, placement of the auxiliary device on the winding tube can be simplified, in particular wherein the contact surface can simultaneously ensure security against falling. Also, for example, if the winding tube is a cardboard tube, the structure of the support surface can be penetrated so that the auxiliary device is supported on the winding tube.

In the context of the invention, the auxiliary body can comprise at least one second contact surface, which is arranged at an angle to the first contact surface. In particular, the angle can be less than or equal to 150 °, preferably less than or equal to 135 °. As a result, the contact surfaces can produce a prismatic shape, so that different diameters of winding cores can be taken into account. It can preferably also be provided that the support surfaces are separated by a depression which runs in particular in the center of the auxiliary body. This can be beneficial to winding cores different radii through the contact surfaces, since small radii lie deeper in the auxiliary body. In addition, the notch effect can be reduced at the point at which the contact surfaces meet and, in particular, a possible, production-related dirty edge between the contact surfaces can be avoided. However, it is in particular also conceivable that both contact surfaces are realized by a curved, single surface element. The arrangement of the support surfaces can thus in particular also increase the flexibility of the auxiliary device compared to winding cores of different diameters and, at the same time, the retention of the auxiliary device on the winding core.

According to the invention, the stop means comprises a blade, which in particular has a thickness of less than or equal to 1 mm, preferably less than or equal to 0.6 mm. The blade can be made particularly thin and preferably have a sharpened edge area. Furthermore, the stop means can be provided, for example, as a sheet metal element, for example made of stainless steel. This offers the advantage that the sling is particularly robust against loads and adverse environmental conditions within a production facility. If the stop means comprises a blade, this also offers the advantage that the blade can be inserted between two sleeve parts and so 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 with the reference.

Within the scope of the invention, it can further be provided that the auxiliary device comprises a switching element, by means of which the alignment means can be converted from an activated state to a deactivated state, the alignment of the winding tube on the reference being possible via the auxiliary device if the alignment means is in the position activated state, and wherein the alignment of the winding tube to the reference via the auxiliary device is impossible when the alignment means is in the deactivated state. In this case, the switching element can in particular advantageously be arranged opposite a direction of bearing of the alignment means on the auxiliary body. The switching element can be understood to mean a component or an assembly which can preferably be operated by an operator and is accessible electrically or manually. The switching element can include a button that 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 enables the status 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 operating position or is switched on in an active state. The direction of sight can in particular be understood as a target direction of the alignment means, under which the reference can be aimed, or the target direction can be understood as the direction of action of the alignment means, in which in particular the alignment means and the reference lie with respect to one another. The switching element has the advantage that the alignment means can be protected or energy can be saved by a temporarily deactivated state. This results in an increased robustness of the auxiliary device. In addition, there can be the advantage that the safety of the auxiliary device is increased by the provision of a deactivated state of the alignment means if, for example, the alignment means is a laser, which can impair an operator's eyesight when viewed. By arranging the switching element in relation to the direction of sight of the alignment means, the ergonomics can also be increased further, so that it can be actuated, for example, with a thumb. Alignment can thereby be further simplified.

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

In the context of the invention it can further be provided that the auxiliary body is made of a plastic. Such a plastic can have, for example, polyethylene, polypropylene or polyvinyl chloride. The plastic can particularly preferably be a polyamide. Furthermore, the plastic can in particular be glass or carbon fiber reinforced. The auxiliary body can preferably be a cast part or a milled part. Thus, the auxiliary body can be produced inexpensively and at the same time be robust against falling or other extreme situations of the auxiliary device. Furthermore, the auxiliary body can advantageously be formed in one piece with the stop means, in particular so that the stop means is also made of plastic. However, the auxiliary body and the stop means can also be formed in several parts, the stop means preferably having a metal or a hard plastic and in particular the auxiliary body being made of plastic. According to a further aspect of the invention, a method for aligning a winding tube with a reference is claimed. The process has the following steps:

• Placing an auxiliary device on the winding tube so that a stop means of the auxiliary device is brought into contact with a counter-stop means of the winding tube,
• joint displacement of the auxiliary device and the winding tube until the winding tube is aligned with the reference via an alignment means of the auxiliary device.

In this context, the common shifting can be understood to mean that the auxiliary device is placed, for example, on the winding tube or fixed thereon, the shifting being realized by pushing the auxiliary device and / or the winding tube.

A preparatory step can preferably also be provided, the winding tube being plugged onto a tube holder of a winding machine. The method thus also offers a particularly simple, flexible and secure possibility of aligning a winding tube. Furthermore, a post-processing step can advantageously be provided, in which the winding tube is fixed in its position on the tube holder by a tensioning means of the winding tube or the tube holder. The auxiliary device can preferably be designed according to one of Claims 1 to 13. A method according to the invention thus brings the same advantages as have been described in detail with reference to a device according to the invention.

• Überführen des Ausrichtmittels von einem deaktivierten Zustand in einen aktivierten Zustand.

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

• Transfer of the alignment means from a deactivated state to an activated state.

The alignment means can preferably be transferred before the alignment of the winding tube on the reference. By providing the different states, energy can be saved. Furthermore, the security of the method for aligning the Winding sleeve can be improved if the active state of the alignment means can pose a risk of injury, such as when the operator looks directly into a laser source.

The steps of a method according to the invention can preferably take place in the given order or in another order. In particular, individual steps or all steps of the method can be repeated or can be repeated.

In the following figures, the same reference numerals are used for the same technical features of different exemplary 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 tube holder 3 of the winding machine 4 with a reference 1 in a first embodiment. 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 is brought into contact with a counter-stop means 5 of the winding tube 2, 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 interacting with one another . The counter stop means 5 can preferably be an end face of the winding tube 2. The stop means 12 further comprises a blade 12.2, which extends from the auxiliary body 11 in the direction of a cylinder axis of the winding tube 2. In order to align the winding tube 2 with the reference 1, the auxiliary device 10 also has an alignment means 13, the alignment means 13 and the stop means 12 having a definable relationship to one another. The stop means 12 can be placed against the counter stop means 5 at least substantially or completely in a stop plane 20.

Furthermore, the alignment means 13 is arranged such that the alignment means 13 and the reference 1 lie essentially in a parallel or identical plane with the stop plane 20. This results in a Direct connection between the axial positioning of the counter-stop means 5, which can preferably be an end face of the winding tube 2, and the reference 1. Reference 1 can, in particular, the end of a second, in particular in the winding process, end of a second, particularly in the winding process, end of a second winding tube 2.1 second sleeve receptacle 3.1. The second winding tube 2.1 can be wrapped or wrapped, for example, by a product winding 7, which is in particular a film winding, which is pressed on via a contact roller 6 of the winding machine 4 in order to produce a product winding 7 that is as compact as possible and / or to avoid air pockets. So that the winding tube 2 can be aligned with the reference 1 via the auxiliary device 10, the alignment means 13 is in an activated state I, so that it acts in a direction of bearing 13.2 and a user determines the relative position of the winding tube 2 with reference 1 or the second one Can estimate or determine the winding tube 2.1. The alignment means 13 can preferably be an optical alignment means which allows an operator to sight the reference 1 in the direction of the bearing 13.2 or emits it in the direction of the bearing 13.2, so that, for example, a light marking is produced. If the winding process of the product roll 7 around the second winding sleeve 2.1 is completed and the winding sleeve 2 is oriented as intended, the auxiliary device 10, which is particularly mobile, can be removed from the winding sleeve 2, so that the second winding sleeve 2.1 and the winding sleeve 2 are rotated by means of a rotating device 8 Winding machine 4 can be swapped in their positions. As a result, the second winding tube 2.1 can be removed with a finished product winding and the new winding tube 2 can be wrapped. Advantageously, the winding tube 2 can be fixed in an aligned position by a tensioning device of the winding tube 2 and / or the tube receptacle 3, so that the winding tube 2 does not slip on the tube receptacle 3 even 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, viewed from the side, which is the view of the Figure 1 opposite. It is clear here that the auxiliary device 10 is arranged on the winding tube 2 with a channel element 14 of the auxiliary body 11 open at the bottom, so that in connection with the in FIG Fig. 1 Shown means 12, which is brought into contact with the counter-stop means 5, and the auxiliary device 10 only a rotational degree of freedom on the Winding sleeve 2 remains. The alignment means 13 can thus preferably be a linear 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 using the reference 1.

Fig. 3 shows the auxiliary device 10 according to the invention for aligning the winding tube 2 on a tube holder 3 of the winding machine 4 according to the first embodiment in a plan view. It is clear here that the winding sleeve 2 is aligned axially by means of the auxiliary device 10 until the alignment means 13 is aligned with the reference 1. This can ensure that a relationship between the positioning of the winding tube 2 and the second winding tube 2.1 is ensured. It is therefore particularly advantageous if the alignment means 13 is arranged in such a way that the alignment means 13 and the reference 1 lie at least essentially in an identical plane to 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 has a counter stop surface 5.1. However, other configurations are also conceivable here, such as a parallel plane.

The auxiliary device 10 of the first exemplary embodiment can additionally or alternatively in particular also according to the Figures 5 to 6 , preferably according to the auxiliary devices of the embodiments of the Figures 4 or 7 be trained.

Fig. 4 shows an auxiliary device 10 according to the invention in a schematic side view in a further embodiment. The auxiliary device 10 has an auxiliary body 11 with a first partial body 11.1 and a second partial body 11.2. Furthermore, a stop means 12, which comprises a blade 12.2, is arranged on the second partial body 11.2 of the auxiliary body 11. On the first partial body 11.1 of the auxiliary body 11 there is also an alignment means 13 which is suitable for aligning the winding tube 2 with a reference 1, as shown, for example, in the first exemplary embodiment. The stop means 12 and the aligning means 13 have a definable relationship to one another, which in the present exemplary embodiment can be, for example, the distance from the center of the aligning means 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 be designed such that the stop means 12 is adjustable relative to the alignment means 13. As a result, a changed relationship between stop means 12 and alignment means 13 can be generated. For this purpose, for example, the first and the second partial bodies 11.1, 11.2 can advantageously be adjustable relative to one another, this adjustment being able to 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 tubes 2, for example in order to separate them or to align a single winding tube. In addition, a grip means 15 is provided on the auxiliary body 11. The grip means 15 can preferably be through a groove which is introduced 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 down. The flexible securing means of the winding machine 4 can 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. The auxiliary device 10 has an auxiliary body 11, wherein a grip means 15 is attached to each of two opposite sides of the auxiliary body 11. The grip means 15 is preferably designed as a groove. As a result, an operator can grip the auxiliary device 10 from above and thereby engage the grip means 15. Furthermore, the auxiliary device 10 has a channel element 14, which is formed in particular by two parts of the auxiliary body 11 which project downwards. A channel axis 14.1 runs along the main direction of extension of the auxiliary body 11, in particular perpendicular to the plane of the drawing. Furthermore, a first and a second contact surface 18 are formed on the auxiliary body 11, which are oriented at an angle 18.1 to one another. The angle 18.1 can preferably be less than or equal to 150 °, particularly preferably less than or equal to 135 °. The support surfaces 18 are designed to be brought into contact with a winding tube 2. In order to ensure an improved hold in this regard, it can further be provided that the support surfaces 18 are structured. For example, knurling of the bearing surfaces 18 or a knob-like structure can be provided in order to increase the coefficient of friction. A groove 18.2 is also provided between the contact surfaces 18, so that the notch effect is reduced at this point and different diameters of winding cores 2 can be taken into account in particular.

Fig. 6 shows an auxiliary device 10 according to the invention with an auxiliary body 11, each of which comprises a grip means 15 on two opposite sides. For this purpose, a channel element 14 is also formed, which is open on the underside. Furthermore, support surfaces 18 are formed on the underside of the auxiliary body 11, so that the auxiliary device 10 with the support surfaces 18 can be placed on a winding tube 2. By means of 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 cores 2 can advantageously be taken into account. As an alternative, the auxiliary device 10 can also 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 can in particular also be provided as an additional component which is attached to a section of the auxiliary body 11. Furthermore, as can be seen in the partial broken view, a light module 13.1 of an alignment means 13 is arranged in the auxiliary body 11. This can advantageously be inserted through an opening into a bore in the auxiliary body 11, so that the assembly of the auxiliary device 10 is also inexpensive. Furthermore, a switching element 17 is arranged next to the alignment means 13, which is designed to switch between an activated I and a deactivated state II (shown here) of the alignment means 13. As a result, the total energy consumption of the alignment means 13 can be reduced and thus the mobility of the auxiliary device 10 can be increased. The safety during the alignment can also be increased by the switching element 17, in particular so that possible sources of danger that can result from an activated state of the alignment means 13 are reduced. The switching element 17 is in particular also within the scope of the exemplary embodiments of the Figures 1 to 5 and 7 to 8 applicable.

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 a grip means 15 on two opposite sides, the grip means 15 in each case being designed in particular as a groove. However, other forms of grip means, such as an additional component, are also conceivable here. Furthermore points the auxiliary device 10 has an alignment means 13 which is in a determinable relation to a stop means 12. The state shown here is a deactivated state II of the alignment means 13, this being, for example, by a switch unit 17, such as, for example, in FIG Fig. 6 shown, can be converted into an activated state I. The stop means 12 further comprises a blade 12.2 which protrudes from the auxiliary body 11 via contact surfaces 18 for placing the auxiliary device 10 on a winding tube 2 and thereby provides a stop plane 20. The support surfaces 18 form a channel element 14 which is open on one side, a groove 18.2 being provided between the support surfaces 18. Furthermore, the auxiliary body 11 has a functional compartment 16.1. The functional compartment 16.1 can be provided as an opening through which an energy 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 can be provided for the alignment means 13 and / or an adjustability of the stop means 12. As a result, for example, a laser of the alignment means 13 can be operated independently of an external energy 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 that 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 can also be formed from a plastic, preferably a polyamide. The stop means 12 can be provided in one piece with the auxiliary body 11 or attached to it. In the case of a multi-part configuration, the stop means 12 can also preferably be made of a stainless steel. Furthermore, in particular the energy unit 16 and / or the functional compartment 16.1 are also advantageously within the scope of the first exemplary embodiment and within the scope of the exemplary embodiments of the Figures 4 , 5 , 6 and 8th applicable.

Fig. 8 shows a method according to the invention for aligning a winding tube 2 with a reference 1 in a schematic representation. In this case, placement 102 of an auxiliary device 10 on the winding tube 2 is provided, so that a stop means 12 of the auxiliary device 10 is brought into contact with a counter-stop means 5 of the winding tube 2. This is followed by a common displacement 103 of the auxiliary device 10 and the winding tube 2 until the winding tube 2 and the reference 1 are aligned by means of an alignment means 13 of the auxiliary device 10. Preferably, a transfer 101 of the alignment means can also 13 from a deactivated state II to an activated state I, in particular before placing 102 the auxiliary device 10. Individual steps of the method 100 can be repeated any number of times and the entire method 100 can also be repeated, for example to align a plurality of winding tubes. The method 100 thus offers a flexible, simple possibility of aligning the winding tube 2 with the reference 1 by means of the auxiliary device 10.

The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, if technically meaningful, individual features of the embodiments can be freely combined with one another without departing from the scope of protection of the invention defined by the claims.
