    The invention relates to a drive system for a Profilieranlage, a Profilieran¬lage for longitudinal-forming a metal strip or an output profile in a profile or pipe, and provided with a spline coupling elements, as described in the claims 1,8 and 17.
    EP 2 452 760 B1 discloses a profiling machine for longitudinally forming a metal strip or starting profile into a profile or tube by means of a plurality of roll forming tools with a coupling stand for such a profiling machine. Arithmetic shafts are provided on a plurality of scaffolding uprights and roll forming tools are arranged thereon, which can be displaced in drive motion by means of a drive system associated therewith. The drive system here comprises a separate coupling stand, on which two coupling units, each with first coupling elements, are arranged one above the other to form a coupling device. The second coupling elements of the coupling devices are each formed by Viel¬keilwellen, which are connected to the Rollenumformwerkzeuge bearing Ar¬beitswellen. The individual coupling units are adjustable in axial direction with respect to the working shafts relative to the coupling stand voneiner a engaged coupling position of the two Kupplungselemen¬te in a disengaged uncoupling position of the two coupling elements. Each of the coupling units is in drive connection via its own steering shaft with a common gear block. The drive of the gear block is effected by a drive motor.
    In other known profiling several auxiliary stands in the direction of flow of the profiling are successively fixed to this arranged on a base frame on which auxiliary stands at least two superimposed an¬ Kupplungseinheiten with each first coupling elements are arranged höhenverisierbar it. The scaffold stands supporting the drive shafts are arranged on an intermediate frame and are supported on the base frame in an adjustable manner relative to the auxiliary stand in the transverse direction with respect to the passage direction of the profiling installation. For engaging or uncoupling the drive shafts, the entire intermediate frame together with the scaffolding uprights in the transverse direction with respect to the auxiliary stand relative to this shift. The ande auxiliary stands arranged coupling units are in each case via own Kardanwellen with a common gear in drive connection. The drive in turn is in drive connection with a drive motor.
    It is the object of the present invention to provide a drive system and a profiling system with such drive systems for longitudinally forming a metal strip or an output profile into a profile or tube, wherein the operating speeds of the individual roll forming tools can be easily adapted to the respective geometry of the article to be manufactured. Furthermore, however, the coupling processes between the coupling elements should still be facilitated or be easier and safer for the operator.
    An object of the invention is solved by the features of claim 1.
    The advantage resulting from the features of claim 1 lies in the fact that a compact drive system can be provided, in which each of the individual clutch units arranged on the drive stand comprises a separate transmission and its own drive motor. The drive with the drive motor thus forms for each clutch unit its own drive unit, which can be driven or operated independently of other clutch units with their drive units. Although this requires a higher number of gears and drive motors for the formation of the drive systems, it has the advantage that, depending on the roll forming tools required for the shaping, these are individually and exactly adapted to the geometry of the counterpart tool to be produced.
    Standes tuned and trained. So even on the otherwise usually used auxiliary stands can be dispensed with.
    In addition, however, the possibility is also created to be able to adjust each of the roller forming tools connected to the individual coupling units to the necessary circumferential speed with its corresponding rotational speed. Thus, a very accurate speed adjustment is made possible so as to be able to adjust the speed and, associated therewith, the peripheral speed of the individual roller forming tools exactly to the passage speed of the article to be manufactured in the course of its shaping. With this, even smaller diameters of the roll forming tools can be used and, as a result, grinding marks on the finished product can be prevented. This also results in a higher product quality. In addition, a reworking of the shaping contours is possible even with auf¬getretenem wear of the individual Rollenumformwerkzeuge. In such a case, the external diameter will usually decrease, whereby the individual drive units of the coupling units have the peripheral speed exactly required for the reworked roll forming tool, e.g. can be easily adjusted by increasing the drive speed.
    Another advantage is also that with such Antriebssyste¬men an economical production of small lots is possible. This is just in profiling of particular advantage.
    Also advantageous is a further embodiment according to claim 2, characterized in that an even shorter installation space can be achieved transversely to the passage direction of the profiling. This can be dispensed with additional components, which on the one hand plant costs and on the other hand storage costs verrin¬gert or can be avoided. Furthermore, however, a simpler mutual alignment of the two coupling elements relative to each other can also take place.
    Also advantageous is an embodiment according to claim 3, since thus even with zuei¬nander different mutual alignments of the teeth only by short circumferential adjustment a safe coupling process ermög¬licht. Furthermore, this also achieves a better, more uniform transmission of the drive torques.
    The embodiment according to claim 4 makes it possible to provide a compact drive unit for driving the coupling element in the region of the drive system. By placing the drive motor directly on the gearbox, however, additional transmission devices such as cardan shafts or the like can be dispensed with, which can provide an even more compact and shorter package of the drive system.
    According to another embodiment variant according to claim 5, a stable base is thus created for the height adjustment of the individual coupling units and thus achieved sufficient guidance accuracy. Moreover, a simple replacement can easily take place in the event of a defect in one of the drive parts, since only the drive unit affected by it can be dismantled from guide slides and replaced by a new drive unit.
    A further development according to claim 6 is also advantageous, since this enables a mutual height-wise alignment of the two coupling elements to be brought into clutch engagement. If the two positioning elements are brought into abutment against one another, a corresponding height-wise and axial alignment relative to one another is achieved. In this prepositioned position of the two Kuppπlungselemente each other, these can then be brought into coupling engagement with each other for the transmission of the drive torque.
    In the embodiment according to claim 7 it is advantageous that on a centrally arranged drive stand on both sides of the same, the corresponding coupling units are guided independently adjustable. Thus, a compact drive system with a corresponding number of Kupp¬lungseinheiten can be created on a drive stand. Furthermore, the individual coupling units or their drive units can be held in zueinan¬der different height alignment on the drive stand.
    The object of the invention is, however, also solved by the features of claim 8. The advantages deriving from the combination of features of this claim are that such a profiling system can be created in which an economical production of small batch sizes is also made possible. Furthermore, the retooling outlay can thus be kept relatively low, since the provision of the coupling elements which can be driven independently of each other enables the corresponding drive speed for each of the individual roll forming tools to be adjusted individually, even when changing the individual roller forming tools.
    As a result of the embodiment according to claim 9, the individual framework stands can be easily exchanged with the roll forming tools after uncoupling of the coupling elements. Are some of the Ge¬rüstständer rebuilt with the new Rollenumformwerkzeugen arranged thereon in the course of the conversion process, smaller units of the drive systems with the Antriebsstän¬ be heightened in height and then brought into clutch engagement wer¬den. This allows an even faster change from a profile geometry to be produced to a further geometry to be subsequently produced.
    Also advantageous is an embodiment according to claim 10, since in the case of a defect of individual drive components, for example, only a single drive system has to be brought into a disengagement position in order to be able to quickly remove it. In addition, the coupling operation is facilitated by the smaller number of coupling elements to be engaged with one another, since the lower number makes it possible to respond more quickly and thus more reliably to possible incorrect couplings.
    According to an embodiment as described in claim 11, relative positioning relative to the base frame is thus achieved in at least one of the positions. This unintentional adjustment movements can be prevented. Inweiterer consequence also injuries to the operator but also mechanical damage to the coupling elements can be prevented.
    In this case, an embodiment according to claim 12 proves advantageous, since a simpler automated adjustment for the operating personnel is feasible and manual adjustment movements to be performed are no longer required. Furthermore, by the lateral arrangement of the adjusting device a leicht¬re accessibility and ease of maintenance can be achieved.
    According to an advantageous development according to claim 13, a more generally adjustable drive assembly can thus be created.
    However, an embodiment according to claim 14 is also advantageous since it is thus possible to provide a common base frame on which both the drive systems and the frame stands can be arranged, fastened and supported. As a result of this direct juxtaposition of the drive systems and the stand, a smaller system width can thus be achieved in the transverse direction to the direction of passage. As a result, the space requirement can be minimized, so that a higher density of profiling systems can be achieved with the same hall size.
    In accordance with claim 15, the possibility is thus created to arrange all system parts of the An¬triebssysteme above the base frame, whereby the accessibility and ease of maintenance can be further improved.
    Finally, however, is also an embodiment, as described in claim 16 mög¬lich, since the corresponding Be¬triebparameter can be stored in dependence on the arranged on the working shafts Rollenum-shaping tools for the object to be produced. In the case of renewed demand, it is possible precisely to retrieve these operating parameters for driving the drive motor provided for this purpose and set them to obtain the corresponding output rotational speed and / or output torque of the coupling element. Thus, a high repeat accuracy can be achieved without high Einstellaufwander.
    However, the object of the invention can be solved independently by the features of claim 17. It is advantageous that remains only a relatively small cross section as a possible Kontaktflä¬che by the decreasing in the axial direction cross sections of the individual spline teeth in the region of the end face of the shaft or the hub. Thus, the process of engagement can be facilitated much easier, since so the tapered individual spline teeth in the range of mutually facing spline ends can be easily inserted into the further Kupplungsele¬ment. Thereby, within certain limits, a mutual self-adjustment of the two coupling elements about their longitudinal axes can be achieved, if a direct mutual engagement is not immediately possible.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.
    In each case, in a highly simplified, schematic representation:

    Fig. 6 is designed as a spline hub second coupling element, inschaubildlicher representation.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component designations, wherein the disclosures contained in the entire description can be applied mutatis mutandis to the same parts with the same reference numerals or the same component designations , Also, the location information chosen in the description, such as up, down, laterally, etc. related to the directly described and illustrated figure and these conditions are to be transferred in a change in position mutatis mutandis to the new situation.
    In Fig. 1 a profiling system 1 according to the prior art is shown instark simplified representation. This profiler 1 comprises at least two mutually spaced base frames 2, 2a. The base frame 2 defines two clamping planes 3, 4 in the present embodiment.
    Furthermore, the profiling plant 1 comprises a plurality of scaffold stands 5, which are arranged one behind the other in the working direction or passage direction of the article to be produced, on which working shafts 6 are mounted in a height-adjustable manner. Depending on the profile or tube to be produced, the necessary roll forming tools 7 can be held or arranged on the individual working shafts 6. The number of roll forming tools 7 depends on the profile cross section of the object to be produced, with several roll forming tools 7 also being provided on one of the working shafts 6 can be arranged.
    In this exemplary embodiment shown here, the framework stands 5 are held in position on a separate intermediate frame 8 and are jointly supported in the vertical direction with respect to the direction of passage of the profiling installation 1 on the base frame 2. Furthermore, an auxiliary stand 9 is provided here, on which, depending on the number of working shafts 6, coupling units 10 are likewise adjustable in height, that is, they are adjustably held in the vertical direction with respect to the clamping planes 3, 4. The adjustment movement can take place by means of a wide variety of adjusting means.
    The coupling units 10 are on the side facing away from the scaffolding uprights 5 side each have their own propeller shafts 11 with a common gear 12 in drive connection. This gearbox 12 drives at the same time at least the two cardan shafts 11 and thus subsequently, when the coupling units 10 are engaged, the working shafts 6 and the roll forming tools 7 arranged thereon for forming. The transmission 12 may in turn be driven by a drive motor 13. Both the gear 12 and the drive motor 13 are mounted on the other base frame 2a.
    Since the cardan shafts 11 are driven by a common gear 12, an individual adaptation of the circumferential speed of the individual roller forming tools 7 is only possible to a limited extent here. Furthermore, the space required by the lateral arrangement of the propeller shafts 11, the transmission 12 and the drive motor 13 in addition to the auxiliary stand 9 is not negligible. Thus, in this embodiment shown here, the drive motor 13, the gear 12, the cardan shafts 11 and arranged on the auxiliary stand 9 Kupplungsein¬heiten 10, a drive system 14 from.
    In FIGS. 2 and 3, an optionally independent embodiment of the drive system 14 is shown, wherein the same reference numerals or component designations are used for the same parts as in the preceding FIG. This embodiment of the drive system 14 may represent a first aspect of the present invention.
    The drive system 14 shown here is provided for driving roller forming tools 7 of the profiling installation 1 held on the framework stands 5. Thus, only the drive system 14 is shown in the two FIGS. 2 and 3, wherein in the following FIG thus be driven Rollenum¬ forming tools 7 together with the scaffold stands 5 are shown and described.
    The drive system 14 comprises at least one drive stand 15, which is connected to its base frame 2 facing side, for example, with a base plate 16. Furthermore, the drive system 14 comprises at least two coupling units 10, wherein the coupling units 10 are adjustable on the drive stand 15 in its height extent. Since in the present exemplary embodiment the drive stand 15 is aligned in the vertical direction with respect to the clamping plane 3, 4 and the clamping plane 3, 4 here has a horizontal orientation, the drive stand 15 has a vertical orientation.
    It can thus be seen from FIG. 3 that each of the coupling units 10 comprises first coupling elements 17 for forming coupling devices 18. Thus, each of the coupling devices 18 comprises the first coupling elements 17 in the region of the drive system 14 and second coupling elements 19, which are not shown here in detail, and in the region of the stand 5 additionally shown in FIG. 4, are drivingly connected to the working shafts 6 hen or arranged or formed on this.
    Furthermore, it is still provided here that each of the first coupling elements 17 of the individual coupling units 10 is in drive connection via its own gearbox 12 with an ei¬genen drive motor 13. In this embodiment shown here, the first coupling element 17 is formed by an output shaft of the transmission 12. Furthermore, the output shaft of the transmission 12 can be provided, for example, with splined teeth, splines or a polygonal profile so as to enable a simpler coupling possibility with the respective associated second coupling element 19 in the region of the scaffold post 5.
    In order to achieve a compact design, it can further be provided here that the drive motor 13 is fastened directly to the transmission 12 and is in driving connection therewith. Due to the narrow, space-saving elongated design of the transmission 12, the drive motor 13 is fastened on the side facing away from the coupling element 17 and thus on the rear or rear of the transmission 12.
    As a result of this design, a compact drive unit is created for each individual coupling unit 10 for each individual roller forming tool 7.
    The coupling unit 10 may further comprise a guide carriage 20. Je¬der of the guide carriage 20 is adjustably guided on the drive stand 15, wherein the adjustment can be done for example by means of a variety of actuating means, such as cylinders, stepper motors or the like. Wei¬ters is still provided here that on each of the guide carriage 20, a separate gear 12 is attached thereto. However, the transmission 12 can also be designed so that already a part of the transmission housing ausbil¬det the guide carriage 20 and thus a pertinent compact unit can be created. Since, in the present exemplary embodiment, the drive motor 13 is also fastened to the drive 12, a simultaneous adjustment of the drive unit comprising the drive motor 13 and the drive 12 takes place when the guide carriage 20 is adjusted.
    As already mentioned above, the drive stand 15 serves for the height-adjustable mounting and mounting of at least one of the coupling units 10. Depending on the number of working shafts 6 on one of the frame stands 5, for each of the individual working shafts 6 a separate coupling unit 10 with the respective drive unit to arrange it.
    If, for example, two superposed working shafts 6 are provided on a framework stand 5, two such coupling units 10, each with its own transmissions 12 and drive motors 13, are also to be provided on one side of the drive stand 15.
    The drive stand 15 is formed in the present embodiment so that both sides of the drive stator 15 in the direction of passage of the Profilieranlage 1 seen, at least two coupling units 10 can be provided. Thus, a drive system 14 is formed here, which is made of at least four coupling units 10 with the respectively associated drive units. The two-sided arrangement of the coupling units 10 on a drive stand 15 so that two frame stand assemblies can be driven with their work shafts 6.
    The drive stand 15 may, for example, have a rectangular shape in its cross-section, on both sides of which first guide elements of a longitudinal guide can be arranged or formed. At each of the guide Schlit¬ 20 more guide elements are provided, which engage in the arranged on Antriebs¬ stator 15 first guide elements. Since the narrow side of the drive stand 15 is facing the framework stands 5, the two first guide elements can be arranged at a distance from one another on the longitudinal side of the drive stand 15 in the vertical direction with respect to the passage direction of the profiling installation 1. By this Distan¬zierung a higher guidance accuracy is achieved.
    Preferably, the adjusting means - in the present case cylinder-piston arrangements - are arranged on the side facing away from the frame stands 5 side of the An¬triebsständers 15 in order to perform an individual adjustment of the individual coupling units 10 can. Thus, each of the individual Kupp¬lungseinheiten in the vertical direction can be aligned exactly to the respective working shaft 6.
    In order to be able to carry out this pre-positioning before the engagement process of the first and second coupling elements 17, 19 of the coupling device 18 can take place between the individual working shafts 6 arranged on the frame uprights 5 and the coupling units 10 which can be brought into engagement therewith, for example a Positioning device 21, be provided.
    The positioning device 21 is best seen from a synopsis of Figs. 3 and 4. For example, each of the individual coupling units 10 can be provided or equipped with a first positioning element 22. In the present embodiment, the first positioning elements 22 are hereby arranged, for example, on the transmission 12 and are designed as stops. The first positioning elements 22 could also be arranged or formed, for example, directly on the guide carriage 20. In the present exemplary embodiment, the first positioning elements 22 protrude from the gearbox 12 in the direction of the frame stands 5.
    3 and 4, the positioning device 21 comprises in the region of the individual frame stands 5 at each of the working shafts 6 further positioning elements 23. The further positioning elements 23 can be adjusted together with the respective second coupling element 19 on the frame stand 5 be held. It is essential that, when one of the working shafts 6 is adjusted, the additional positioning element 23 provided for this purpose is also adjusted in order to always maintain the same distance ratios.
    As a result, with a corresponding arrangement and alignment of the further positioning elements 23 with appropriate pre-adjustment of the individual working shafts 6 with the roll forming tools 7 arranged or held thereon, a relative position corresponding to the object to be manufactured is set on the respective frame stands 5. In order to achieve an axial advance direction of the individual coupling units 10 with respect to the individual working shafts 6 before the two coupling elements 17, 19 are engaged, the coupling units 10 with the first positioning elements 22 arranged thereon are moved along the drive column 15 as long as possible in each case cooperating positioning elements 22, 23 of the positioning devices 21 are provided, for example, in response to each other. In the present exemplary embodiment, provision is made for the first positioning element 22 of the coupling unit 10 arranged on top to be arranged or formed in such a way that it can be brought from above in the direction of the clamping plane 3, 4 onto the further positioning element 23 in abutment , In the case of the below-arranged coupling unit 10, however, the first positioning element 22 is to be brought from below onto the direction away from the clamping plane 3, 4 with the further positioning element 23.
    This pre-adjustment takes place when not yet engaged first and second coupling elements 17,19. If each of the individual coupling units 10 vorposi¬ tioned to the individual, associated and later to be driven working shafts 6, the entire drive system 14 can be adjusted in the axial direction on the Gerüst¬ stand 5 and thus each of the first and second coupling elements 17,19 are brought into coupling engagement with each other.
    Regardless, however, a non-contact embodiment of the positioning device 21 would also be possible. So could e.g. 17 may be arranged in the region of the first Kupplungsele¬ments a transmitter. In the region of the second coupling element 19, a triangular mirror designed as a reflector could be arranged. Laser beams, they are re¬flektiert by Dreikantspiegel. The adjusting adjustment takes place until the proper alignment of the two coupling elements 17, 19 with each other has been achieved.
    Regardless of this, however, it would also be possible to design the drive stand 15 as a frame element with stanchions arranged side by side in the direction of passage and distanced from one another. The individual posts can also be seen in the direction of passage through each other by connecting webs to a verbun¬den. In the free spaces between the individual uprights, the at least two coupling units 10 are each guided vertically adjustable. The vertical adjustment can be done by a variety of actuators.
    FIG. 4 shows an embodiment of the profiling plant 1, which may be independent of itself, wherein again the same reference numerals apply to the same parts. Part designations are used as in the preceding Figs. 1 to 3. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 2 and 3 or reference is made. Here, the uncoupling position of the drive system 14 is shown by the Ge equals 5.
    The drive system 14 previously described in FIGS. 2 and 3 serves to drive the roller forming tools 7, which are guided via the working shafts 6 to the associated scaffolding uprights 5. The construction of the framework stands 5 with their working shafts 6 and roller forming tools 7 can be chosen freely according to the known state of the art.
    In this embodiment of the profiling 1, the common Grundrah¬men 2 is provided, which defines at least one Aufspannebene3, 4 on its upper side. On the base frame 2, a plurality of scaffolding uprights 5 are supported, which carry the Rollenumformwerkzeuge 7 on the working shafts 6. The drive of the plurality of Rollenumformwerkzeugen 7 takes place by a plurality of successively arranged in the direction of passage drive systems 14th
    As described above, each drive system 14 has the drive stand 15, wherein each of the drive stands 15 of the profiler 1 in each case in a senk¬ right aligned with respect to the direction of flow of profiling 1 Füh¬rungsanordnung 24 and in a parallel direction with respect to the clamping plane 3, 4 on the base frame is guided adjustable. In this case, the adjustment of each of the drive systems 14, in particular their drive racks 15, can take place relative to the base frame 2 by means of at least one adjusting device 25. In the present embodiment, the adjusting device 25 is connected on one side to the An¬triebsständer 15, in particular its base plate 16. Furthermore, the adjusting device 25 is also connected to the base frame 2 in order to be able to transmit the necessary adjusting force to the drive stand 15. Preferably, the adjusting device 25 is arranged laterally next to the drive stand 15 with respect to the direction of passage of the profiling machine 1. Thus, the actuator 25 is located at the top of the base frame 2, whereby a simple accessibility and space-saving arrangement can be created here.
    By providing the individual drive systems 14 with their drive stands 15, it is possible for each of the individual drive stands 15 to move independently of each other from an engaged coupling position of the individual coupling elements 17, 19 into an uncoupled disconnection position of the coupling elements 17 , 19 is adjustable. Depending on the number of coupling units 10 provided on the drive stand 15 or their drive units, the number of coupling units 10 to be coupled to the scaffolding uprights 5 can thus be maintained in a manageable and easily manageable number.
    Furthermore, the individual drive stands 15 or the drive systems 14 thus formed can each be held in at least one of the two positions, namely the coupling position and / or the uncoupling position, positioned relative to the base frame 2. This can be done, for example, by locking elements of a locking device, not shown, so as to avoid unwanted adjustment and thus possible damage to system parts or injury to operators. Independently of this, however, it would also be possible for a plurality of drive systems 14, arranged in succession in the direction of passage of the profiling installation 1, in particular their drive stands 15, to be combined to form a related drive system group and connected together to form a larger unit.
    In the present embodiment, a common base frame 2 is provided, which has on its upper side the first clamping plane 3 and the second mounting plane 4. At the first clamping level 3, here the individual drive systems 14 with their drive racks 15 and on the second clamping level 4 the scaffold racks 5 are arranged or supported. Thus, here are the two Aufspannebenen 3, 4 seen in the direction of passage of the profiling 1, immediately adjacent to the common base frame 2 arranged or trained. In this case, the second clamping plane 4 can be aligned in a vertical direction above the first clamping plane 3 and in a parallel direction with respect to these.
    Since here each of the individual working shafts 6 is assigned its own drive motor 13 or via the transmission 12 and the coupling device 18 is in drive connection, each of the drive motors 13 of the drive systems 14 is connected to a motor control. The plurality of motor controls are fernermit with a central, not shown Profilieranlagensteuerung verbun¬, wherein in a storage means of Profilieranlagensteuerung Betriebsparame¬ter are stored as configuration data.
    This makes it possible to drive each of the individual roller forming tools 7 to the respective working shafts 6 by the individual control of the individual drive motors 13 with the exact predetermined speed. In this way, each of the individual roll forming tools 7 can be formed and tuned in its diameter exactly to the geometry of the respective object to be produced. As a result of the independent driving of the individual working shafts 6 with the roller forming tools 7 arranged thereon, the optimum drive torques and / or working speeds and, associated therewith, the peripheral speed can be determined and stored for each roller forming tool 7. It thus becomes possible, even with smaller batch sizes depending on the requisite roll forming tools 7, to repeat the corresponding working speed of the individual drive motors 13 in a repeatable manner and thus to be able to operate them.
    When changing the profile or article to be produced, the roll forming tools 7 held thereon are to be replaced by corresponding other roll forming tools 7 at the individual scaffold stands 5. In order to be able to make a more rapid exchange, the corresponding roll forming tools 7 can be positioned and fastened to the respective working shafts 6 on equipment stands 5 that are not currently required. This Vorberei¬tungsvorgang can be carried out parallel to the ongoing operation of profiling 1.
    If the profiling system 1 is set to stand still, the uncoupling of the individual drive systems 14 takes place, bringing the engaged coupling elements 17, 19 out of engagement. This can be done, for example, by means of the above-described positioning devices 25 with which the individual drive stands 15 and thus the drive systems 14 formed therefrom are displaced so far away from the scaffolding uprights that sufficient freedom of movement to the scaffold quick-change is present. It is possible to monitor the end positions. In a further consequence, the individual coupling units 10, in particular their guide carriages 20, can be moved into a basic or initial position relative to the drive column 15. If the individual scaffold stands 5 are replaced by the scaffolding stands 5 which are prepared in advance and which carry the new roll forming tools 7, the individual drive systems 14 can again be brought into driving connection with the scaffold stands 5 opposite to them and thus the roll forming tools 7. Before that, however, the individual coupling units 10 are to be spent in the vertical direction in an opposite axial orientation with respect to the working shafts 6. For this process of height adjustment, the positioning device 21 with the two positioning elements 22, 23 serves.
    If one of the drive systems 14 is located in a corresponding, oppositely positioned orientation of the two coupling elements 17, 19, the engagement process can be initiated. The thus-oriented drive system 14 can be moved in the direction of the stand 5 with the adjusting device 25 assigned to it. This transverse adjustment of the individual drive systems 14 takes place, for example, via the guide arrangement 24. By means of the actuating device or devices 25, the individual drive systems 14 are adjusted until reaching an engaged end position.
    If individual ones of the coupling elements 17, 19 can not be immediately brought into coupling engagement with one another, a clearance for not immediately engaged coupling elements 17, 19 can be created on one of the coupling elements 17 and / or 19 by means of an axial preload. For locking the Kupplungsele¬mente 17,19 can be approached in a Reversierbe¬trieb subsequently profiling 1. If all the drive systems 14 are brought into drive connection with the opposing scaffold uprights 5 via the coupling devices 18, a renewed production of another object to be produced and converted can take place.
    In order to enable passive running of individual ones of the working shafts 6, individual ones of the working shafts can for example be uncoupled by manually pulling the corresponding splined shaft. Alternatively, however, a freewheel sleeve could also be mounted. The disadvantage here is that for the installation of the freewheel sleeve first the profiling machine must be emptied in order to perform the installation can. However, disengagement by pulling splined shafts is also possible when profiling machine 1 is in operation.
    FIGS. 5 and 6 show an optionally independent embodiment of one of the coupling elements 17, 19 for the drive system 14 of the profiling installation 1, again with the same reference numerals or component designations for the same parts as in the preceding FIGS to 4 are used. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding FIGS. 2 to 4 or reference is made. As the coupling element 17, as described above, the Abtriebswel¬le of the transmission 12 are used.
    Subsequently, excellently formed portions of the two coupling elements 17, 19 are each referred to as splined teeth 26. In the case of the first coupling element 17 designed here as an output shaft, the splined teeth 26 project in the radial direction from the shaft body. In the case of the sleeve-shaped second coupling element 19, on the other hand, the spline teeth 26 protrude in the direction of the longitudinal axis. The second coupling element 19 may also be referred to as a spline shaft. The individual splines 26 are limited in the circumferential direction seen by splines 27. The splines 27 extend in Axi¬alrichtung and preferably parallel to each other. Each of the splines 26 has spline ends 28 in the disengaged position on its side facing the respective opposite coupling element 19, 17.
    In order to facilitate mutual engagement of the coupling elements 17, 19, the individual end portions facing the respective opposing coupling element, 19, 17, namely the splined ends 28, of the splines 26 may have transition splines 29 facing each other in the axial direction. It can also be spoken by a taper of the individual splines 26.
    The tapering of the cross sections of the individual splines 26 and thereby achieved reduction of the spline tooth widths can be achieved with a variety of Längsver¬läufen. Thus it would be possible to see each spline end 28 in radial direction on the longitudinal axis, e.g. to form with a radius. The immediately adjoining transition splines 29 can be rectilinear and / or arcuately curved and extend from the spline ends 28 extending to the splines 27. Thus, although a higher processing effort is necessary for the production, but which further facilitates the Ein¬kupplungsvorgang subsequently and minimizes the Gefahrpoten¬tial of injury to the operator.
    In addition to this, it would also be possible to provide insertion chamfers of the same design as in the case of the second coupling element 19 provided here as a spline hub, as can be seen from FIG. In this way, the surfaces of the spline ends 28 coming into abutment with each other when the mutual coupling position is not perfect can be further reduced.
    Furthermore, it would also be possible, just before the mutual engagement bring the two coupling elements 17,19, that only with the Antriebssmo¬or 13 in drive connection coupling element 17 to put into Drehbe¬wegung only briefly so zukönnen the coupling movement zukönnen.
    This reduction of the splined tooth cross-sections as described above in the circumferential direction can also be applied to other types of teeth.
    It should also be noted that the first coupling element 17 can not be designed as a splined shaft but as a spline hub. The second Kupp¬lungselement 19 is then form in this case as a splined shaft.
    The embodiments show possible embodiments of the Antriebssys¬tems 14 and the Profilieranlage 1, wherein it should be noted at this point that the invention is not limited to the specifically illustrated embodiments thereof Ein¬, but also various combinations of the individual Ausführungsvarianten are mutually possible and this possibility of variation due to the teaching of technical action by objective invention lies in the skill of those skilled in the art.
    Furthermore, individual features or combinations of features from the different embodiments shown and described can also represent solutions that are inventive, inventive or inventive.
    The problem underlying the independent inventive solutions can be taken from the description.
    Above all, the individual in Figs. 2, 3; 4; Figures 5, 6 show the subject matter of independent solutions according to the invention. The related objects and solutions according to the invention can be found in the detailed descriptions of these figures.
    For the sake of order, it should finally be pointed out that in order to better understand the structure of the drive system 14 and of the profiling system 1, this or its components have been shown partially unevenly and / or enlarged and / or reduced in size.
