The winding mandrel 12 is moreover embodied rotatable. The winding mandrel 12 is supported rotatably about a winding axis 38. The winding mandrel 12 is embodied as a clamping mandrel. Hence the winding mandrel 12 comprises a plurality of clamping jaws (not shown). The winding mandrel 12 is in at least one operating state provided for carrying a carrier of material to be wound 14, 15 via a force-fit connection (cf. also FIG. 2).

(9) Furthermore the winding device comprises a transporting unit 16. The transporting unit 16 is embodied as a pivot arm. The transporting unit 16 is made of stainless steel. A component of the winding mandrel 12 is arranged on the transporting unit 16. In the present case the second mandrel unit 42 is fixated to the transporting unit 16. Alternatively it is also conceivable to embody a winding mandrel in a one-part implementation, and in particular to entirely fixate said winding mandrel to a transporting unit. The transporting unit 16 is further supported movably. The transporting unit 16 is in the present case supported on rails 44. The transporting unit 16 is supported in such a way that it is displaceable in an axial direction 46. The transporting unit 16 is herein displaceable along a straight line. The transporting unit 16 is in the present case displaceable in parallel and/or along the winding axis 38. Consequently an axial position of the transporting unit 16 is changeable. In addition, the transporting unit 16 is supported on a rotary shaft 48. Thereby the transporting unit 16 is supported in such a way that it is pivotable about a pivot axis 30. The pivot axis 30 extends in parallel to the winding axis 38. Consequently a pivot position of the transporting unit 16 is changeable. A maximum pivot angle of the transporting unit 16 is in the present case approximately 190. Alternatively it is also conceivable to implement a transporting unit in such a way that an axial position or a pivot position of the transporting unit is not changeable.

(10) Beyond this the winding device comprises a positioning unit 18. The positioning unit 18 is provided for changing a spatial position of the transporting unit 16. In the present case the positioning unit 18 is provided for at least substantially adjusting a spatial end position of the transporting unit 16 according to requirement. For this purpose the positioning unit 18 comprises at least one positioning element 20, 22. In the present case the positioning unit 18 comprises two positioning elements 20, 22. The positioning elements 20, 22 are provided, in a well-known fashion, to adjust the position of the transporting unit 16. The first positioning element 20 is provided for changing the axial position of the transporting unit 16. The first positioning element 20 comprises a first drive unit (not shown), which is embodied as an electromotor. Moreover the first positioning element 20 comprises a ball screw (not shown), which is provided to convert a rotary movement of the first drive unit into a translational movement of the transporting unit 16. The second positioning element 22 is provided for changing the pivot position of the transporting unit 16.

The second positioning element 22 further comprises a gearing (not shown), which is provided for converting a rotary movement of the second drive unit into a pivot movement of the transporting unit 16. Alternatively it is conceivable that a first positioning element and a second positioning element are embodied at least partly in a one-part implementation and/or in a one-part implementation. It is moreover conceivable to use any other kind of positioning elements deemed expedient by someone skilled in the art, e.g. at least one pneumatic and/or at least one hydraulic positioning element.

(11) For the purpose of capturing a position of the transporting unit 16, the positioning unit 18 further comprises at least one position capturing unit 26, 28. In the present case the positioning unit 18 comprises two position capturing units 26, 28. The first position capturing unit 26 is provided for capturing the axial position of the transporting unit 16. The first position capturing unit 26 is arranged on the pivot axis 30. The first position capturing unit 26 is at least partly fixated to the rotary shaft 48. The first position capturing unit 26 is embodied as a rotary encoder. In the present case the first position capturing unit 26 is embodied as an absolute-value encoder. The second position capturing unit 28 is provided for capturing the pivot position of the transporting unit 16. The second position capturing unit 28 is arranged on the pivot axis 30. The second position capturing unit 28 is at least partly fixated to the rotary shaft 48. The second position capturing unit 28 is embodied as a rotary encoder. The second position capturing unit 28 is embodied as an absolute-value encoder. In the present case the first position capturing unit 26 and the second position capturing unit 28 are embodied at least partly in a one-part implementation. Alternatively it is also conceivable to have at least two position capturing units embodied in a one-part implementation and/or completely separate from each other. It is moreover conceivable to implement at least one position capturing unit as a relative-value encoder, in particular incremental encoder. Furthermore at least one position capturing unit could be arranged in a position that differs from a pivot axis.

(12) The position capturing units 26, 28 are provided to detect an actual position of the transporting unit 16 and to feed said actual position to the control unit implemented as a digital signal. The control unit is provided to compare the digital signal to a required position of the transporting unit 16 that is stored in the memory unit, and to actuate the positioning unit 18 in such a way that the actual position of the transporting unit 16 is equivalent to the required position at least substantially. In the present case at least substantially any desired type of end positions of the transporting unit 16 may be stored and/or programmed in the memory unit of the control unit.

(13) The winding device may moreover comprise further units. In the present case the winding device comprises a feed unit for carriers of material to be wound 24. The feed unit for carriers of material to be wound 24 is provided for storing carriers of material to be wound 14, 15 which are to be processed and for making these available for processing. For this purpose, the feed unit for carriers of material to be wound 24 comprises a feed opening for carriers of material to be wound 50, which is in particular arranged in the winding machine housing 34. The winding device also comprises a feed unit for material to be wound 52. The feed unit for material to be wound 52 is provided for rendering a material to be wound 10 available and for feeding the material to be wound 10 to the carrier of material to be wound 14, 15 (cf. also FIG. 2). For this purpose the feed unit for material to be wound 52 comprises in the present case at least one supplying unit 54 and a pulley 56 as well as an electrically adjustable traversing drive 58, which is in particular movable along the winding axis 38. To sever the material to be wound 10 the winding device further comprises a movably supported severing unit 60. Alternatively a supplying unit may also be embodied as a pulley. It is moreover conceivable to completely dispense with a supplying unit.

(14) Beyond this the winding device comprises a foiling unit 62. The foiling unit 62 is provided for packaging a fully processed carrier of material to be wound 14, 15. For this purpose the foiling unit 62 comprises a receiving shaft 64 for receiving a foiling coil 66 (cf. also FIG. 2). The receiving shaft 64 is supported rotatably about a rotary axis 68. Moreover the foiling unit 62 comprises a foiler 70. The foiler 70 is provided to align a foil of the foiling coil 66 and to arrange the foil of the foiling coil 66 on the material to be wound 10 of the fully processed carrier of material to be wound 14, 15. For the purpose of function control and/or maintenance control, the foiling unit 62 furthermore comprises a foiler capturing unit 72. The foiler capturing unit 72 is provided to capture a movement of the foiling coil 66. The foiler capturing unit 72 is implemented as a rotary encoder. The foiler capturing unit 72 is embodied as a relative-value encoder, in particular as an incremental encoder. The foiler capturing unit 72 is arranged on the rotary axis 68. The foiler capturing unit 72 is at least partly fixated to the receiving shaft 64. Via the foiler capturing unit 72 a packaging process of the fully processed carrier of material to be wound 14, 15 can be monitored and controlled in a simple fashion. Herein a pre-defined quantity of foil may be arranged on the material to be wound 10 of the carrier of material to be wound 14, 15. In particular, by capturing the rotary movement of the foiling coil 66 it is advantageously detectable if a packaging process is executed and/or if an error occurs in the packaging process, e.g. in case the foil of the foiling coil 66 has been used up. Alternatively a foiler capturing unit could also be implemented as an absolute-value encoder, as a laser sensor and/or as another type of sensor deemed expedient by someone skilled in the art. It is also conceivable to arrange a foiler capturing unit in a different position and/or to entirely dispense with a foiler capturing unit.

(15) FIG. 2 shows the winding device during a winding process, wherein the transporting unit 16 is in a winding operative position. In the present case the winding device serves to wind the material to be wound 10 onto the exchangeable carrier of material to be wound 14, 15. Alternatively it is also conceivable to use the winding machine for winding a material to be wound off a carrier of material to be wound. The material to be wound 10 is in the present case equivalent to a ribbon-shaped material to be wound. However, using other materials to be wound with a geometry differing from a ribbon-shape is also conceivable.

(16) For the purpose of winding the material to wound 10, the winding mandrel 12 and thus the carrier of material to be wound 14, 15 is driven rotatingly about the winding axis 38. During a winding process, a mass of the material to be wound 10 that has already been wound onto the carrier of material to be wound 14, 15 is determined continuously and/or in discrete steps. For this purpose the control unit comprises a mass sensor (not shown), which is provided for determining a mass characteristic and/or the actual mass of the material to be wound 10 that has already been wound. Alternatively other sensors deemed expedient by someone skilled in the art are also conceivable for determining a wound material to be wound, e.g. a sensor for measuring a length of a material to be wound and/or a circumference sensor for determining a diameter of the material to be wound that has already been wound.

(17) If a given quantity of a material to be wound 10 is located on the carrier of material to be wound 14, 15, the winding mandrel 12 is stopped and the wound material to be wound 10 is separated from the remaining material to be wound 10 by means of the severing unit 60. Then the wound material to be wound 10 is packaged by means of the foiling unit 62. Alternatively it is also conceivable to do without packaging by a foiling unit.

(18) Then follows a setting-down process (cf. FIG. 3). In this setting-down process the transporting unit 16 is provided for transporting the fully processed carrier of material to be wound 14, 15 away out of the winding operative position into a storage place for carriers of material to be wound 74. The positioning unit 18 is herein provided for translationally displacing the transporting unit 16 out of the winding operative position into a setting-down operative position by means of an axial translational movement and a pivot movement. The setting-down operative position is in the present case at least substantially equivalent to at least substantially any kind of a spatial position, which may in particular change between two winding processes and depending on a quantity of material to be wound 10 that has already been wound. According to the invention, the spatial end position of the transporting unit 16 may herein be at least substantially adjusted according to requirement, as a result of which a manual position adaption of possible mechanical stops between the winding processes may be dispensed with. Alternatively it is also conceivable that a positioning unit is provided for translationally displacing a transporting unit, via an axial translational movement and a pivot movement, out of a receiving operative position and/or out of at least substantially any other desired position, preferably end position, of the transporting unit into a setting-down operative position.

(19) When the carrier of material to be wound 14, 15 is removed, the carrier of material to be wound 14, 15 is entirely supported by the second mandrel unit 42. Firstly the transporting unit 16 and hence the carrier of material to be wound 14, 15 is in the winding operative position. In a first step the distance between the first mandrel unit 40 and the second mandrel unit 42 is increased. Herein the first positioning element 20 is provided to increase the axial position of the transporting unit 16 and thus of the second mandrel unit 42 with respect to the winding machine housing 34 and/or to the first mandrel unit 40. In a second step the second positioning element 22 is provided to change the pivot position of the transporting unit 16 by approximately 90, in particular in a positive direction of rotation. In a third step the first positioning element 20 is provided to reduce the axial position of the transporting unit 16 with respect to the winding machine housing 34 and/or to the first mandrel unit 40 until the transporting unit 16 and thus the carrier of material to be wound 14, 15 is situated in the setting-down operative position. Then the force-fit connection between the second mandrel unit 42 and the carrier of material to be wound 14, 15 can be released, as a result of which the carrier of material to be wound 14, 15 is supported in the storage place for carriers of material to be wound 74.

(20) Subsequently a receiving process follows (cf. FIG. 4). In this receiving process the transporting unit 16 is provided to receive a further carrier of material to be wound 14, 15, which is arranged in the feed unit for carriers of material to be wound 24 and is to be processed, from the feed unit for carriers of material to be wound 24 and to transport said further carrier of material to be wound 14, 15 into the winding operative position. The positioning unit 18 is herein provided for translationally displacing the transporting unit 16 out of the setting-down operative position into a receiving operative position via an axial translational movement and a pivot movement. The receiving operative position is in the present case equivalent to at least substantially any desired spatial position, which may in particular change depending on a carrier of material to be wound 14, 15 that is made use of. Alternatively it is also conceivable that a positioning unit is provided for translationally displacing a transporting unit out of a winding operative position and/or out of at least substantially any desired other position, preferably end position, of the transporting unit into a receiving operative position via an axial translational movement and a pivot movement.

(21) When the further carrier of material to be wound 14, 15 is delivered, the further carrier of material to be wound 14, 15 is entirely supported by the second mandrel unit 42. In the present case the transporting unit is firstly located in the setting-down operative position.

(22) In a first step the first positioning element 20 is provided to increase the axial position of the transporting unit 16 and thus of the second mandrel unit 42 with respect to the winding machine housing 34 and/or to the first mandrel unit 40, as a result of which the second mandrel unit 42 is removed in particular out of the carrier of material to be wound 14, 15. In a second step the second positioning element 22 is provided to change the pivot position of the transporting unit 16 by approximately 180, in particular in a negative direction of rotation. In a third step the first positioning element 20 is provided to reduce the axial position of the transporting unit 16 with respect to the winding machine housing 34 and/or to the first mandrel unit 40 until the transporting unit 16 is located in the receiving operative position, as a result of which the second mandrel unit 42 is introduced into the further carrier of material to be wound 14, 15. Following this, a further force-fit connection may be established between the second mandrel unit 42 and the further carrier of material to be wound 14, 15, in particular via an actuation of the clamping jaws. In a fourth step the first positioning element 20 is provided to increase the axial position of the transporting unit 16 and thus of the second mandrel unit 42 with respect to the winding machine housing 34 and/or to the first mandrel unit 40, as a result of which the further carrier of material to be wound 14, 15 removed out of the feed unit for carriers of material to be wound 24. In a fifth step the second positioning element 22 is provided to change the pivot position of the transporting unit 16 by approximately 90, in particular in a positive direction of rotation. In a final step the first positioning element 20 is provided to reduce the axial position of the transporting unit 16 with respect to the winding machine housing 34 and/or the first mandrel unit 40 until the transporting unit 16 and thus the further carrier of material to be wound 14, 15 is in the winding operative position, as a result of which a further winding process may take place.

(23) The exemplary winding machine described and its functionality are herein provided just for exemplarily illustrating the invention and are absolutely not to be a restriction thereof.
