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. Another role-handling system to be considered as the closest prior art is disclosed in the document US Pat. No. 5,941,474 disclosed. 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 object is achieved by a method having all the features of claim 13 or 14. In the respective dependent claims, possible embodiments of the invention are described.

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 processing of a plurality of sleeves or rollers, the present invention has a winding shaft which is detachably attached on one side to a holding device, which is advantageous in the sliding of the sleeves in the movement of the receiving unit in the direction of the transfer station. Of course, the one-sided attachment of the winding shaft also has the advantage that the rollers, which are transferred from the winder of the transfer station, in turn, easily removed from the winding shaft can be. Since the winding shaft is fixed on one side, the winding shaft on a free end, which faces the feed unit, wherein the free end is arranged on the side of the winding shaft, which is arranged opposite the one-sided releasable attachment point. About this free end of the roller handling system according to the invention is able to postpone a plurality of sleeves on the winding shaft and to take a variety of roles of the winding shaft, wherein the feed unit moves in the direction of transfer station or in the direction feed unit and the sleeves or the roles moved. Thus, with the roll handling system according to the invention, an automatic roll change can be achieved in a very short time, while at the same time maximum machine speeds, in particular the winder can be achieved.

Advantageously, the winding shaft can be inclined downwards relative to the horizontal axis so that the winding shaft is inclined at an angle α to the horizontal axis, with the angle α being ≦ 5 ° in particular. 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 may 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 or the sleeves, whereby each sleeve can learn about the resulting friction additional positioning. As a result, the sleeves are positioned on the winding shaft, which plays a major role for the winding quality in the winder. For example, it is conceivable that the free end of the winding shaft, which faces the supply unit, is inclined downwards.

According to the invention it can be provided that the winding shaft has fixing means which serve to fix the sleeves on the winding shaft. After the sleeves have been positioned on the winding shaft, it may be advantageous that when transferring the winding shaft to the winder, the sleeves remain in their desired position. For this purpose, the fixing means are in use, which prevent the sleeves lose their position on the winding shaft.

For example, in an embodiment according to the invention, it may be conceivable that the fixing means on the winding shaft are movable clamping elements which are arranged between one extended position and a retracted position are movable, in particular in the extended position, the clamping elements projecting from the winding shaft extend. The clamping elements can be z. B. on the lateral surface of the winding shaft, wherein the clamping elements are movable via a drive between the extended and the retracted position. The drive can be integrated in the transfer station. Furthermore, it may be advantageous that in the extended position, the clamping elements directly against the inner circumferential surface of the sleeves form and / or non-positively, whereby a reliable fixation of the sleeves on the winding shaft can be achieved. Furthermore, a centering of the sleeves on the winding shaft can be achieved via the clamping elements, so that each sleeve can achieve an ideal position on the winding shaft, both along the axial extent of the winding shaft and along the radial extent of the winding shaft.

In one possible embodiment of the invention, the roller handling system can be designed such that the winding shaft has an air supply and / or an air discharge, can be introduced and / or discharged through the air in the winding shaft, whereby the clamping elements are movable. The drive of the clamping elements is achieved by introducing air into the ventilated winding shaft, wherein under a defined air pressure, the clamping elements move in their extended position and the venting elements move back to their retracted position at a vent. This makes it possible to achieve a movement of the clamping elements.

Advantageously, the transfer station may comprise at least one check valve to maintain the extended position of the clamping elements. The maintenance of the extended position of the clamping elements is advantageous because when transferring the winding shaft in the winder, a positional shift of the sleeves is not desired.

The roller handling system according to the invention may further provide that the holding device comprises a movable bolt which is movable between a locking position and a release position, wherein in the locking position, the bolt is located in a receptacle of the winding shaft, wherein the receptacle is designed as a groove. About this configuration of the holding device can be a reliable solvable Achieve attachment of the winding shaft to the holding device, which is mounted on one side within the roll handling system.

In addition, according to the invention, the roll handling system can be designed such that the winding shaft has a further receptacle, which is arranged adjacent to the first receptacle, wherein in the further recording a gripping element of the winder can be introduced, wherein in particular the further receptacle is designed as a groove. The gripping element penetrates into the further receptacle and transfers the winding shaft into the winder. As a result, an accurate position is achieved in the winder, since the gripping element has a geometry that corresponds to the geometry of the further recording and thus ensures that when transferring the winding shaft this is in its required position within the winder itself.

In order that air can be introduced into the winding shaft as reliably as possible during ventilation and venting and discharged out of the winding shaft, it has been found that the air supply and / or air discharge is to be arranged particularly favorably in the region of the end face of the winding shaft. For example, it is conceivable that a nozzle is introduced in the ventilation and / or venting in the air supply and / or in the air discharge in order to operate a ventilation and / or a venting of the winding shaft. The air supply may be a bore or a channel within the winding shaft. The air discharge can correspond to the air supply, although in a further embodiment of the invention, the air discharge can be located separately from the air supply to the winding shaft. Like the air supply, the air discharge can also be a bore, a channel, etc. in the winding shaft, in order to achieve a movement of the clamping elements into their stated positions.

Furthermore, the invention includes that the end face is designed as a polygon, in particular that the end face is designed as a trihedron. The geometric design of the end face has the advantage that within the winder, a counter element acts on this polygon or receives this positive and / or non-positive, so that the winding shaft is rotated during winding of the material web with a corresponding speed. The design of the end face as a polygon has the advantage that high torques can be transmitted to the winding shaft within the winder.

The FIGS. 1 to 11 schematically show a roll 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 reels 3 of the receiving unit 20 have already been transferred, wherein the receiving unit 20 has a first support 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 FIG. 3 and FIG. 6 , The rollers 3 are then transferred again from the winder 50 to the transfer station 60, which in FIG. 4 and FIG. 5 is shown.

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 in FIG. 12 is shown, wherein the sensor unit 100 checks the passing sleeves 1, to what extent the sleeves 1 correctly rest on the receiving unit 20 and / or the correct sleeves 1 on the receiving unit 20 are. According to FIG. 12 For example, 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 110, 120 is a scraper element 81, which is flexible according to the present embodiment and may be formed from a spring plate. Of 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 by means of the positioning device 80 on the receiving unit 20. 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, which in particular in FIG. 13 to FIG. 15 is clarified. 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 are according to FIG. 12 each on one or more positioning means 24, whereby the sleeves 1 have an oblique position on the first bearing surface 23 of the receiving unit 20, which in FIG. 12 is clarified. Now occurs a movement of the receiving unit 20 from the position according to FIG. 1 in the direction FIG. 2 , the scraper element 81 contacts 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 sleeve 1 has already been positioned over the wiper element 81, wherein the sleeve 1 abuts with its left portion against the positioning means 24, which in FIG. 13a is shown. 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 leveling means 24 which serve as a stop for the middle sleeve 1. This one is also in FIG. 15 shown.

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 positioning device 80, to which the gluing device 90 and the sensor unit 100 are integrated, can be displaced, during the movement of the pick-up unit 20 with the sleeves 2 in the direction of the transfer station 60 in accordance with FIG FIG. 2 the position device 80 occupies a working position 21, which in FIG. 12 is shown. The position device 80 can be further brought into a waiting position, which schematically in FIG. 6 and FIG. 7 is shown in which no application of the adhesive medium and / or the verification of the diameter of the sleeves 1 is necessary.

According to the FIGS. 1 to 11 For example, the transfer station 60 has a holding device 61, to which a winding shaft 62 is releasably attached. During the movement of the sleeves 1 by means of the receiving unit 20 in the direction transfer station 60, the sleeves 1 are threaded onto the winding shaft 62 and pushed, so that the sleeves 1, the position in FIG. 2 to reach. The winding shaft 62 is mounted on the holding device 61 on one side and fixed, which in FIG. 16 . FIG. 17 and FIG. 21 is shown. 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 down, which in FIG. 21 is shown schematically. 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 in the movement of the receiving unit 20 in the direction of the transfer station 60, a guide element 29 ensures that the short-term Winding shaft 62 is brought into the horizontal axis 4. 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 in FIG. 21 are shown schematically. 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. In this case, 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 the FIGS. 14 and 15 equivalent.

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.

Thus, the sleeves 1 remain fixed on the winding shaft 62, in particular also within the winder 50, the winding shaft 62 fixing means 54 which in FIG. 18 and FIG. 20 are shown. 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 in FIG. 18 shown around the lateral surface of the winding shaft 62 around evenly 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 feed 57 in the winding shaft 62, which in FIG. 19 is shown schematically. The air supply 57 is aligned axially with the winding shaft 62. The air is adjusted according to FIG. 16 introduced via a nozzle 58, wherein the nozzle 58 is first moved into the air supply 57. About the self-adjusting within the winding shaft 62 pressure, the clamping elements 54 drive in the defined extended position 55. 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 in FIG. 16 shown 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 an axial securing for the winding shaft 62, and that when the winding shaft 62 in the holding device 61 of the transfer station 60 is located. In particular, when pulling out the rollers 3 of FIG. 6 in the direction of the feed unit 10 according to FIG FIG. 7 high forces can act on the winding shaft 62. The axial fuse 60 is then in a locking position 59 (see FIG. 17 ), wherein in the locking position 59, the axial securing 60 in a receptacle 63 according to FIG. 18 located. The receptacle 63 is formed according to the illustrated embodiment as a groove in the winding shaft 62.

In addition to the axial securing 60, the holding device 61 on holding plates 66, 67 which act in the sense of a toggle lever with a defined force on the winding shaft 62, which schematically in FIG. 16 is shown. 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 in the further receptacle 64, a gripping member 51 of the winder 50 can be introduced, which schematically in FIG. 3 to FIG. 5 is shown. 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 of the Transfer station 60 is moved into the winder 50 and back from the winder 50 in the transfer station 60. 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, if the rollers 3 according to FIG. 4 the transfer station 60 have been handed over, 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 rest reliably on the receiving unit 20, the axial securing device 60 is brought into its locking position 59 and the holding plates 66, 67 move to 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 be released from the winding shaft 62 and move to a position which in FIG. 8 is shown.

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 FIG. 4 maintains its position, the receiving unit 20 has a lifting device for the second bearing surface 25, the second bearing surface 25 from its position according to FIG. 4 in the direction of roll 3 according to FIG. 5 can move until the roller 3 rests reliably on the second support surface 25. 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 FIG. 10 , Here, the second support surface 25 is deactivated and without Function. In a further rotational position of the receiving unit 20, the second bearing surface 25 is active, which, for example, in FIG. 5 is shown to reliably accommodate the rollers 3. Here, the first bearing surface 23 is deactivated.

According to FIG. 19 is further shown that the air supply 57, which can also serve as air removal during the venting, is arranged on the end face 65 of the winding shaft 62. Here, the end face 65, as in FIG. 18 shown as triangular. The triangular has the advantage that 50 high torques can be absorbed in the winder.

According to the illustrated embodiment according to FIG. 19 the winding shaft 62 has a tilting protection, which is realized in the form of a self-aligning bearing 68, which is movably arranged 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.

Is now the receiving unit 20 with the rollers 3 in the position according to FIG. 7 arrived, the receiving unit 20 rotates about the axis 31. In particular, the second bearing surface 25 moves about the axis 31, the rollers 3 are fed to a Rollenabführung 130 (see FIG. 9 ). The next cycle for the sleeve addition starts, according to FIG. 10 the feeding 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 11, which causes only a sleeve 1 from a channel 12 of the feed 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 11, the receiving unit 20 with its support surfaces 23, 25, guide element 29, transfer station 60, holding device 61, fixing means 54, axial securing 60, holding plates 66, 67, position means 80 and Rollenabführung 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.
