The invention relates to a roll handling system for a winder, in which sleeves can be applied with a material web, so that a plurality of wound on the sleeves with a material web rolls arise. In addition, the invention relates to a method for a just mentioned roll handling system.

A device is known from WO 03/010079 A1, in which a material web can be applied to a rotating sleeve in a winder. The result is a wound on the sleeve with the material roll, which can be removed via a roll handling system from the winder. A major disadvantage in the prior art is that the roll handling system is only able to "edit" a sleeve or a roll or to move. In addition, it has disadvantageously been found that the device mentioned in the prior art is structurally complex.

The object of the present invention is to avoid the above-mentioned disadvantages, in particular to provide a reel handling system for a winder and a method for this purpose, so that the productivity of the overall arrangement and the method can be significantly increased.

The object of the present invention is achieved by a roller handling system having all the features of claim 1. Furthermore, the stated object is achieved by a method having all the features of claim 15. In the respective dependent claims, possible embodiments of the invention are described.

According to the invention, a roll handling system for a winder is proposed, in which sleeves each having a material web can be applied so that a plurality of rolls wound on the sleeves, each with a material web arise, with a feed unit for transferring a plurality of sleeves to a receiving unit, wherein the receiving unit is arranged movably between the feed unit and a transfer station, with which sleeves can be transferred to the winder and rolls can be transferred from the winder to the transfer station, the receiving unit having a first bearing surface with positioning means arranged around the sleeves by means of a between the feed unit and the transfer station Align position device on the receiving unit. A significant advantage of the invention is that a plurality of sleeves can be processed in the roll handling system, among other things, the material webs are applied, thus creating a variety of roles, which can significantly increase the productivity of the overall arrangement. Due to the simultaneous machining of a plurality of sleeves or rollers, the present invention has a receiving unit with positioning means to ensure correct alignment of the sleeves at the transfer station. It has been found that a correct application of the material web to the sleeves is to be ensured, so that an exact positioning of the sleeves within the transfer station is necessary. Only then can a high quality in the application of the web to the individual sleeves in the winder respectively. Since a plurality of sleeves are to be transported in the winder, the positioning means on the first support surface during movement of the receiving unit in the direction of the transfer station ensure that the sleeves are brought into their correct position. According to the invention, positioning of the sleeves takes place during the movement of the receiving unit in the direction of the transfer station. In this case, the positioning device positions the sleeves on the moving receiving unit. If the sleeves arranged adjacent to one another are already in the transfer station, it is no longer necessary according to the invention to readjust or correct the position of the sleeves. Without losing time can be done by the transfer station, a transfer of the sleeves to the winder.

In a further measure improving the invention, provision can be made for the first bearing surface to have shell elements which are at least partially adapted to the geometric shape of the sleeves, with the shell elements in particular being spaced apart from one another. The shell elements, which are formed on their surface by the first bearing surface, can advantageously be made of a metallic material. The surface of the first bearing surface is advantageously adapted to the geometry of the sleeves. The sleeves advantageously have a hollow cylindrical shape, with a defined diameter. The shell elements with one another can be positioned at a distance from one another, wherein at least one positioning means is arranged on the shell elements. It is advantageous that the positioning device is designed such that positioning of the sleeves takes place relative to one another on the first bearing surface of the receiving unit. During the positioning can z. B. the distance to the adjacent arranged sleeves are corrected and adjusted accordingly, at the same time each sleeve is positioned on the receiving unit according to the position means and the positioning means. This can generate an automatic role change, which requires little time. At the same time, the machine speeds, in particular the winder can be increased, whereby the productivity can be increased.

Advantageously, the positioning means projecting from the shell element and / or from the support surface projecting. Advantageously, the sleeves are after being fed to the receiving unit obliquely on the first support surface, since the Sleeves are each located on a positioning means, which extends, for example, projecting from the support surface. During positioning by means of the positioning device, the positioning device contacts at least one or more sleeves, which move via the moving receiving unit in the direction of transfer station, while the sleeve is pushed away from the positioning and it comes to a uniform support of the sleeves with the first bearing surface. For example, it is conceivable that the positioning means are disc-like, in particular formed as metallic discs. The sleeves may for example be made of a plastic, whereby the weight of each roller or sleeve is reduced. In addition, this produces hardly any noise when the sleeves abut against the relevant positioning means.

In a further measure improving the invention, the roll handling system according to the invention can be designed such that the positioning means are arranged laterally on the shell element. The lateral arrangement of the positioning means is due among other things by the ease of installation. For example, the positioning means can be attached laterally to the respective shell element positively and / or non-positively, in particular via a screw connection. An exchange of the positioning means is also conceivable.

Furthermore, the roller handling system according to the invention may be formed with a second support surface of the receiving unit to receive the rollers, in particular that the second support surface is movable independently of the receiving unit. Here, it may be useful to provide two different bearing surfaces on the receiving unit, since the transportable geometry of the sleeves and the rollers may be different, or is. It may also be advantageous that the second support surface can be moved independently of a movement of the receiving unit, for. B. when the winder of the transfer station passes the roles. It is conceivable that the second bearing surface is moved via a lifting drive to safely receive the winding shaft with the rollers.

In addition, the invention includes that the receiving unit is linearly movable between the feed unit and the transfer station and / or has a lifting device, whereby the receiving unit is movable perpendicular to the direction of movement between the feed unit and the transfer station. The lifting device can be designed such that both the first and the second bearing surface can be moved. It is also conceivable that the first and / or the second bearing surface have an independent lifting device. In addition, the invention includes that the receiving unit, when moving towards the transfer station and back, can have a travel path that can be more complex than a linear movement, e.g. B. the path can be arcuate and / or done on a circular path.

Furthermore, it may be advantageous that the receiving unit is arranged rotatable about an axis. Depending on the rotational position of the receiving unit, the first or the second bearing surface is available for the roll handling system. Such a design of the rotating receiving unit favors a compact overall arrangement of the roll handling system.

Further, it may be advantageous that the receiving unit has a guide element which can be brought between an active and passive position, wherein during the movement of the receiving unit in the transfer station, the guide element from the passive position to the active position is movable to one on the Transfer station arranged to bring the winding shaft in position, in particular that the guide element contacted in the active position, the winding shaft and / or shifts the winding shaft in a defined position. In a measure improving the invention, the transfer station may comprise a holding device to which the winding shaft is releasably secured, wherein the sleeves are pushed onto the winding shaft during the movement of the receiving unit in the direction of the transfer station. If the sleeves are completely in their correct position on the winding shaft, the holding device releases the attachment to the winding shaft, which is then fed to the winder. In addition, the winding shaft can be passed back with deferred roles back to the transfer station, the holding device after the transfer closes the attachment to the winding shaft again, so that the rollers can be transported back to a roll removal via a movement of the receiving unit. Thus, the sleeves can be reliably pushed onto the winding shaft and / or the rollers can be easily transported from the winding shaft in the direction of roll removal, the winding shaft is mounted on one side of the holding device and / or fixed. In particular, the bearing of the winding shaft is arranged on the side facing away from the feed unit of the holding device.

The guide element according to the invention, which can be brought between the active and the passive position ensures that when pushing the sleeves on the winding shaft, the winding shaft has the desired horizontal and / or vertical position. Even with the movement of the receiving unit from the transfer station in the direction of feed unit, the guide element can be in the active position and thus directly contact the winding shaft to hold it in the desired position. Advantageously, the guide element has a roller element which rolls in the active position on the winding shaft. The roller element is adapted according to the geometry of the winding shaft. Advantageously, the roller element is made of a plastic, whereby the wear, the weight and the noise level can be kept low.

Advantageously, the position device can be designed such that positioning of the sleeves takes place relative to one another. During positioning, the distance to the adjacently located sleeves can be correspondingly corrected and adjusted, while at the same time positioning each sleeve on the receiving unit via the position device.

Furthermore, it can be provided that the position device has a scraper element, which serves for contacting with at least one sleeve during the movement of the receiving unit in the direction of the transfer station. In this case, the position means is movable, wherein in particular during the movement of the receiving unit with the sleeves in the direction of the transfer station, the position means occupies a working position. During the movement of the receiving unit with the rollers, the positioning device advantageously assumes a waiting position, which differs from the working position. The scraper element contacted during the movement of the receiving unit in the direction of the transfer station, the sleeves and brings them into a correct position on the Receiving unit. Advantageously, the scraper element is immovably positioned on the positioning device when positioning the sleeves on the receiving unit. Expediently, at least in part, the wiper element projects into the travel path of the sleeves in the direction of the transfer station, so that automatically one or all of the sleeves meet the wiper element and are thus positioned in the receiving unit. During the movement of the receiving unit in the direction of the feed unit, the position device or the wiper element is in the waiting position.

Thus, the positioning of the sleeves on the winding shaft is further improved in accuracy, the winding shaft may be inclined to the horizontal axis downwards, so that the winding shaft is inclined at an angle α to the horizontal axis, in particular, the angle α <5 °. For example, it is conceivable that the free end of the winding shaft, which faces the supply unit, is inclined downwards. Due to the slightly oblique arrangement of the winding shaft to the horizontal axis or to the direction of movement of the receiving unit, the winding shaft passes through the individual sleeves, which have the shape of a hollow cylinder. At the same time there is a slight contact with the lateral surface of the obliquely arranged winding shaft and the inside lateral surface of the sleeve, whereby the sleeve or the sleeves experience additional positioning on the winding shaft.

In addition, the object is achieved by a method according to all features of independent claim 15. In the dependent claims possible embodiments of the method according to the invention are described.

According to the invention, a method for positioning sleeves in a roll handling system is proposed with a feed unit for transferring a plurality of sleeves to a receiving unit, the receiving unit being movably arranged between the feed unit and a transfer station, a positioning device being provided between the transfer station and the feed unit, the receiving unit has a first bearing surface with projection-like positioning means extending from the bearing surface, the transfer station has a holding device to which a winding shaft is detachably fastened, the following steps being included: Transfer of the sleeves to the receiving unit, so that at least one sleeve rests on a positioning means, whereby the at least one sleeve has an oblique position on the support surface of the receiving unit,

Movement of the receiving unit in the direction of the transfer station, wherein in this movement, the positioning device acts on the at least one sleeve and the sleeve leaves the oblique position and is pushed onto the support surface of the receiving unit, whereby a first positioning of the at least one sleeve takes place.

It is particularly advantageous that a plurality of sleeves can be processed by the roll handling system, wherein all sleeves are positioned during the movement of the receiving unit before the sleeves are further processed outside the transfer station. Further advantages of the method according to the invention correspond to the advantages which already apply to the roll handling system according to the invention.

In addition, it has been found advantageous that after the first positioning, the receiving unit moves further in the direction of the transfer station and the sleeves are postponed after a travel of the receiving unit on the horizontal axis downwardly inclined winding shaft and the winding shaft acts on the sleeves, the are each positioned on a positioning means of the receiving unit, so that a second positioning of the sleeves takes place. Thus, two positions can be achieved by the method according to the invention, whereby the position quality of the sleeves is increased on the winding shaft. In this case, it is advantageous that, after the first positioning and / or after the second positioning, the sleeves are at a distance from each other. The distance may vary depending on the requirement profile.

Conveniently, the method according to the invention comprises that the sleeves of the feed unit are transferred in such a way that the sleeves roll from the feed unit to the receiving unit and then all the sleeves on the receiving unit are adjacent to one another. The sleeves advantageously roll independently from the feed unit to the receiving unit, wherein previously the receiving unit has been brought into the corresponding rotational position, so that the sleeves reach the first bearing surface. Further advantages, features and details of the invention will become apparent from the following description in which several embodiments of the invention are described in detail with reference to the drawings. The features mentioned in the claims and in the description may each be essential to the invention individually or in any desired combination. Show it:

Figures 1 to Figure 1 1 show schematically a roller handling system for a winder 50, in which sleeves 1, each with a material web 2 can be wound. Here, the roll handling system comprises a feed unit 10 for transferring a plurality of sleeves 1 to a receiving unit 20. According to FIG. 1, three rollers 3 of the receiving unit 20 have already been transferred, the receiving unit 20 having a first bearing surface 23 on which the sleeves 1 rest. The sleeves 1 are cylindrical in this case.

The receiving unit 20 can be moved between the feed unit 10 and a transfer station 60. At the transfer station 60, the sleeves 1 can be transferred to the winder 50, which will be discussed below. In the winder 50, a material web 2 is applied to each individual sleeve 1 and there is a plurality of wound on the sleeves 1 with a material web 2 rollers 3, see for example Figure 3 and Figure 6. The rollers 3 are then again from the winder 50 for Pass transfer station 60, which is shown in Figure 4 and Figure 5.

Between the transfer station 60 and the feed unit 10, a positioning device 80 is provided, which causes the sleeves 1 on the first bearing surface 23 to be positioned when the receiving unit 20 moves in the direction of the transfer station 60. The positioning device 80 is designed such that positioning of the sleeves 1 takes place relative to one another. The position device 80 has a sensor unit 100, which is shown in FIG. 12, wherein the sensor unit 100 checks the passing sleeves 1, to what extent the sleeves 1 rest correctly on the receiving unit 20 and / or the correct sleeves 1 are located on the receiving unit 20. According to FIG. 12, the sensor unit 100 has a first sensor 110, which checks to what extent the diameter of the sleeve 1 is too large with respect to a fixed maximum diameter in order to protect the device of the roll handling system located behind it. If the measured diameter of the sleeve 1 is actually greater than a stored maximum diameter, the roll handling system is aborted. The second sensor 120 checks to what extent the actual diameter of the sleeve 1 corresponds to a predetermined value within the roller handling system. For example, it is conceivable that the machine operator of the roll handling system previously enters the value of the sleeve 1 with respect to its diameter. Subsequently, a comparison between the measured diameter of the sleeve 1 and the previously entered diameter value takes place via the measurement of the second sensor. The sensor unit 100, which is arranged on the position device 80, can thus also determine the extent to which a sleeve 1 is missing, which likewise leads to a rupture of the roll handling system. Between two sensors 1 10, 120 is a scraper element 81, which is flexible according to the present embodiment and may be formed from a spring plate. Furthermore, the positioning device 80 has an adhesive device 90, which is arranged in the direction of the transfer station 60.

In FIG. 12 to FIG. 15 it is shown that the receiving unit 20 has positioning means 24 for aligning the sleeves 1 on the receiving unit 20 by means of the positioning device 80. Here, the first support surface 23 of the receiving unit 20 shell elements 26 which are at least partially adapted to the geometric shape of the sleeves 1. The shell elements 26 are spaced from each other, wherein the positioning means 24 protrude from the support surface 23 projecting manner, which is particularly illustrated in Figure 13 to Figure 15. According to the present embodiment, the positioning means 24 are disc-shaped, wherein the positioning means 24 are designed as metallic discs, which are arranged laterally on the shell elements 26.

When the sleeves 1 are transferred from the feed unit 10 to the receiving unit 20 (see FIG. 10), the sleeves 1 according to FIG. 12 are each located on one or more positioning means 24, whereby the sleeves 1 have an oblique position on the first support surface 23 of the receiving unit 20 have, which is illustrated in Figure 12. If a movement of the receiving unit 20 from the position shown in Figure 1 in the direction of Figure 2, contacted the Abstreiferelement 81 each obliquely arranged sleeve 1, so that the sleeve 1 is brought from the oblique position and is pushed onto the support surface 23 of the receiving unit 20, whereby a first positioning 5 of the sleeves 1 takes place. According to FIG. 12, the right-hand sleeve 1 is already above the scraper element 81 has been positioned, wherein the sleeve 1 abuts with its left portion against the positioning means 24, which is shown in Figure 13a. Thus, the middle sleeve 1 and the left sleeve 1 is positioned, at the same time the receiving unit 20 moves with the sleeves 1 in the direction transfer station 60. At the same time, the diameters of the sleeves 1 are checked via the sensor unit 100. After the first positioning 5 of the sleeves 1, an adhesive medium is applied to the lateral surface of each sleeve 1 via the adhesive device 90. The position device 80 can in this case be a tempering unit and / or a printing unit have in order to apply the adhesive medium on the sleeves 1 according to defined parameters. For example, it is conceivable that the adhesive medium is a hot melt adhesive. The function of the adhesive medium is that reliably in the winder 50, the material web 2 can be attached to the lateral surface of the sleeve 1.

The shell element 26a according to FIG. 12 has two positioning means 24 lying at a height, which serve as a stop for the middle sleeve 1. This is also shown in FIG.

The rearmost shell element 26b has a further positioning means 24, which is increased to the two positioning means 24. This further securing means 24 serves as a securing element in order to avoid tilting in the positioning of the left sleeve 1.

The position device 80, on which the adhesive device 90 and the sensor unit 100 is integrated, can be traversed, wherein during the movement of the receiving unit 20 with the sleeves 2 in the direction of the transfer station 60 according to FIG. 2, the position device 80 assumes a working position 21, which is shown in FIG 12 is shown. The position device 80 can furthermore be brought into a waiting position, which is shown schematically in FIG. 6 and FIG. 7, in which no application of the adhesive medium and / or checking the diameter of the sleeves 1 is necessary.

According to FIGS. 1 to 11, the transfer station 60 has a holding device 61 to which a winding shaft 62 is detachably fastened. During the movement of the sleeves 1 by means of the receiving unit 20 in the direction transfer station 60, the sleeves 1 on the Winding shaft 62 threaded or pushed so that the sleeves 1 reach the position in Figure 2. The winding shaft 62 is mounted on the holding device 61 on one side and fixed, which is shown in Figure 16, Figure 17 and Figure 21. The bearing of the winding shaft 62 is arranged on the side facing away from the feed unit 10 side of the holding device 61. Here, the winding shaft 62 is inclined to the horizontal axis 4 downwards, which is shown schematically in Figure 21. The winding shaft 62 is inclined at an angle α to the horizontal axis 4, wherein the winding α is less than 5 °. The free end 53 of the winding shaft 62, which faces the feed unit 10, is inclined downwards. In order for the free end 53 to be able to enter the hollow sleeves 1 initially during the movement of the receiving unit 20 in the direction of the transfer station 60, a guide element 29 ensures that the winding shaft 62 is brought into the horizontal axis 4 for a short time. The guide element 29 is arranged on the receiving unit 20, wherein the guide element 29 can be brought between an active position 27 and a passive position 28, wherein these positions 27, 28 are shown schematically in FIG. 21. In the active position 27, the guide member 29 brings the winding shaft 62 in the horizontal axis 4, wherein the winding shaft 62 penetrates into the sleeves 1. It is sufficient according to the invention that only partially in the movement of the receiving unit 20 in the direction transfer station 60, the winding shaft 62 has penetrated into one or more sleeves. Subsequently, the guide member 29 can be moved back into the passive position 28, so that the winding shaft 62 moves back to its inclined position. This results in a certain friction with the inner surface of the sleeve 1, wherein the receiving unit 20 continues to move with the sleeves 1 in the direction transfer station 60. The winding shaft 62 acts on the sleeves 1, so that the sleeves 1 are each end-positioned on a positioning means 24 of the receiving unit 20, which is a second positioning 6 of the sleeves 1 on the first bearing surface 23. Here, the sleeves 1 are pressed against the respective positioning means 24, so that each sleeve 1 comes into contact with its positioning means 24, which corresponds to Figures 14 and 15.

According to FIG. 21, the guide element 29 is designed with a roller element 30 which rolls in the active position 27 on the winding shaft 62. As a result, a low friction can be achieved, with hardly any noise is recorded. The roller element 30 may be made of a suitable plastic. So that the sleeves 1 remain fixed on the winding shaft 62, in particular also within the winder 50, the winding shaft 62 has fixing means 54, which are shown in FIG. 18 and FIG. According to the illustrated embodiment, the fixing means 54 are formed as movable on the winding shaft 62 clamping elements which are movable between an extended position 55 and a retracted position 56. In the extended position 55, a fixing of the sleeves 1 takes place on the winding shaft 62, wherein the clamping elements 54 in the extended position 55 projecting from the winding shaft 62 extend and thus rest against the inner circumferential surface of each sleeve 1 with a defined force. In addition, this results in a centering of the sleeves 1 on the winding shaft 62, since in particular, as shown in Figure 18, around the lateral surface of the winding shaft 62 evenly around the fixing means 54 are arranged. During the transfer of the winding shaft 62 with the sleeves 1 to the winder 50 and back from the winder 50 in the direction transfer station 60, the fixing means 54 are in their extended position 55. The drive for moving the clamping elements 54 in their respective position 55, 56 takes place in the present embodiment by air, which is introduced via an air supply 57 in the winding shaft 62, which is shown schematically in Figure 19. The air supply 57 is aligned axially with the winding shaft 62. The air is introduced via a nozzle 58 according to FIG. 16, the nozzle 58 first being moved into the air feed 57. The tensioning elements 54 travel into the defined extended position 55 via the pressure occurring within the winding shaft 62. Before the winding shaft 62 is transferred to the winder 50, the nozzle 58, which is arranged at the transfer station 60, moves back into the position shown in FIG Position. A non-explicitly illustrated check valve prevents the fixing means 54 leave the extended position 55.

According to FIG. 16 and FIG. 17, furthermore, the holding device 61 of the transfer station 60 is shown, which has a movable pin 60 which serves as axial securing for the winding shaft 62, specifically when the winding shaft 62 in the holding device 61 of the transfer station 60 located. In particular, when pulling out the rollers 3 of FIG. 6 in the direction of the feed unit 10 according to FIG. 7, high forces can act on the winding shaft 62. The axial securing device 60 is then in a locking position 59 (see FIG. 17), wherein in the locking position 59 the axial securing device 60 is located in a receptacle 63 according to FIG. The receptacle 63 is formed according to the illustrated embodiment as a groove in the winding shaft 62. In addition to the axial securing device 60, the holding device 61 has holding plates 66, 67, which act on the winding shaft 62 in the sense of a toggle lever with a defined force, which is shown schematically in FIG. This ensures that the winding shaft 62 is fixed on one side to the transfer station 60. According to FIG. 19, the winding shaft 62 has a further receptacle 64, which is arranged adjacent to the first receptacle 63, wherein a gripping element 51 of the winder 50, which is shown schematically in FIG. 3 to FIG. 5, can be introduced into the further receptacle 64. The further receptacle 54 is also designed as a groove, wherein the gripping element 51 is designed according to the geometry of the receptacle 64 and engages in this receptacle 64 when the winding shaft 62 from the transfer station 60 in the winder 50 and back of the winder 50 in the transfer station 60th is moved. During the transfer, the holding device 61 described above is released, so that the axial securing device 60 is detached from the winding shaft 62. This means that the axial securing device 60 does not assume the locking position 59, but is in a release position, not explicitly shown, in which the bolt 60 is positioned at a distance from the winding shaft 62. The holding plates 66, 67 are not applied to the winding shaft 62. The winding shaft 62 is held only by the gripping elements 51.

Now, when the rollers 3 have been handed over in accordance with Figure 4 of the transfer station 60, there is a venting of the winding shaft 62, in which move by the application of air from the winding shaft 62, the clamping elements 54 in their retracted position 56. The receiving unit 20 moves as far as the rollers 3 until a contact with the material web 2 is formed. When the rollers 3 reliably rest on the receiving unit 20, the axial securing device 60 is brought into its locking position 59 and the holding plates 66, 67 move into their holding position according to FIG. 16, in which the winding shaft 62 is reliably held and fixed in the holding device 61. The gripping elements 51, which are movably mounted on the winder 50, can detach from the winding shaft 62 and travel to a position shown in FIG.

So that the rollers 3 can be reliably picked up by the receiving unit 20, the receiving unit 20 has a second bearing surface 25 which, according to the illustrated embodiment, can be moved independently of the receiving unit 20. Although the receiving unit 20 according to Figure 4 maintains its position, the receiving unit 20 has a lifting device for the second support surface 25, which can move the second support surface 25 from its position in Figure 4 in the direction of roller 3 of Figure 5 until the roller 3 the second bearing surface 25 reliably rests. The advantage of two support surfaces 23, 25 of different size and shape is that the geometries of the sleeves 1 and of the rollers 3 are very different. In addition, the weight of the rollers 3 is substantially increased to the weight of the sleeve 1. It is particularly advantageous that the receiving unit 20 is arranged rotatable about an axis 31, wherein in a rotational position, the first support surface 32 is active to receive the sleeves 1, for example in Figure 10. Here, the second support surface 25 is disabled and no function. In a further rotational position of the receiving unit 20, the second bearing surface 25 is active, which is shown for example in Figure 5, to reliably receive the rollers 3. Here, the first bearing surface 23 is deactivated.

According to FIG. 19, it is furthermore shown that the air feed 57, which at the same time can also serve as air discharge during the venting, is arranged on the end face 65 of the winding shaft 62. Here, the end face 65, as shown in Figure 18, designed as a triangular. The triangular has the advantage that 50 high torques can be absorbed in the winder.

According to the illustrated embodiment of Figure 19, the winding shaft 62 on a tilt protection, which is realized in the form of a self-aligning bearing 68 which is movably disposed on the edge of the winding shaft 62. The pendulum bearing 68 is made of a plastic and can prevent that when the winding shaft 62 bends, a tilting of the winding shaft 62 is formed.

Now, if the receiving unit 20 arrived with the rollers 3 in the position shown in Figure 7, the receiving unit 20 rotates about the axis 31st In particular, the second support surface 25 moves about the axis 31, the rollers 3 are fed to a Rollenabführung 130 (see Figure 9). The next cycle for the tube addition starts, wherein, according to FIG. 10, the feed unit 10 approaches the receiving unit 20 and further sleeves 1 are fed to the first bearing surface 23. The feed unit 10 has a separating element 1 1, which causes only a sleeve 1 from a channel 12 of the Feeding unit 10 of the receiving unit 20 is supplied. Advantageously, all units of the roll handling system, in particular the feed unit 10, the separating elements 1 1, the receiving unit 20 with its bearing surfaces 23, 25, guide element 29, transfer station 60, holding device 61, fixing means 54, axial securing 60, holding plates 66, 67, position means 80th and roller discharge 130 via a control unit electronically connected to each other, so that a data exchange can take place with each other. This allows the reel handling system to be further optimized in its efficiency. The winder 50 can also be in data communication with the control unit; in particular, the control unit can be integrated in the winder 50. In addition, the feed unit 10 is designed such that the channels 12 according to Figure 1 or Figure 2 in its width according to the geometry of the sleeve 1 are adjustable, in particular it is conceivable, the feed unit 10 such further form that the number of channels can be varied.

The illustrated embodiment of the roll handling system is particularly advantageous because due to the arrangement of the individual units of the winder 50 is accessible and visible to the operator, which is shown by the arrow view of Figure 1. This is achieved, inter alia, that the holding device 61 is arranged laterally, opposite the feed unit 10 and the roller discharge 130, wherein the winding shaft 62 is held on one side on the holding device 61 releasably.

While the material webs 2 are applied to the sleeves 1 in the winder 50, a roller 3 is formed, each with a material web 2, wherein the material webs 2 on different sleeves 1, which are adjacent to each other, are applied. Subsequently, the rollers 3 of the transfer station 60 are returned again. Before the material web 2 is applied to the sleeve 1, the material web 2 advantageously has a greater width, relative to the extension direction of the sleeve 1, on. This Materialrohbahn, which is not explicitly shown, is separated in an upstream step in the individual material webs 2, wherein a blade cut or a disc knife cut can take place. The step of severing may be, for example, within the winder 50. The gripping elements 51, which act laterally on the winding shaft 62, can translationally extend and retract in their length and pivot about a defined axis, which is shown schematically in FIG. 3 to FIG. 5 or FIG. 8. As a result, the winding shaft 62 can be positioned accurately.
