Device and Method for Winding a Strand-Shaped Winding Material

The invention relates to a method and a device for helically winding a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic, onto a rotating winding drum, in thecaseof thewinding material, such as an extruded plastictube, for example a cable protection tube, in which a fiber optic cable can be laid in a protected manner, it is important, among other things, to stock thewinding material in a length of several hundred meters in the case of limited construction site space, so as to lay it across long distances, in particular underground.

It Is known to wind the winding material onto a winding drum or winding coil and to transport thewound drum to the construction site, it can be unwound on location as needed.

To make production more economical, the winding process directly follows the production process, in particular the extruding of thewinding material, so that the plastic winding material, which was just extruded, leaves a cooling station without being cut and is supplied to the winding device. The winding process itself is then typically controlled by an operator and is manually manipulated, if necessary.

When using a cable protection tube as winding material, a standard winding drum made of wood is typically used. The cable protection tube, which is wound onto the wood winding drum, is delivered to construction sites in order to install it there as needed. Due to a relatively low price and the possible reusability, such cost-efficient, standardized wood winding drums or aiso other winding drums have proven themselves in particuiar in the use on construction sites. Due to imbalances on the lateral side flanges and on the drum core, however, the winding drums have rotationaiiy asymmetrical axial and radial impacts. Due to the geometric irregularity of the winding drum, a winding of the winding material, which is continuously monitored and manipulated by an operator, is necessary according to the prior art. In addition to unforeseeable geometry differences of low-price drums, an automation has also not been attained until now insofar as the material characteristics in the case of plastic tubes furthermore only stabilize after a longer curing time, so that the winding characteristic of the plastic tube is difficult to predict after and during the winding due to changes in the material characteristics after the extrusion. Such individual winding conditions, which are difficult to predict ahead of time, require operating personnel with many years of winding experience when monitoring and manipulating the winding material. As of yet, it has not been possible to attain an at ieast approximately complete automated winding without manual support of an operator in particular at a winding speed of above 100 m per minute.

Winding methods as well as winding devices, in which electric cables are wound onto geometrically accurate rolls, are known per sein the automation technology. EP 0203046 B1 for example discloses a cable winder, in which a guide arm, which is directed towards the winding roll, has a plurality of arm members, which are connected to one another by means of a plurality of arm joint locations, it turned out, however, that ideal conditions are present for the cable as well as for the rotationally symmetrical winding drum in the case of the known winding automation processes, with respect to the geometry of the winding drum as well as the material characteristics of the winding material, in particular wire winders are products of a high material quality and consistent and constant material characteristics. A higher expenditure of costs is made for such winding materials so as to provide winding coils, which have ideal geometries, which are free from imbalances. It turned out that the known automated winding techniques cannot be used successfully when a winding material as well as a winding drum are used, the material or geometry characteristics of which, respectively, are not foreseeable.

An automatic cable winding device for winding cables onto a drum is known from DE 24 41 090 A1, which has a traversi ng device for guiding the cables in response to the wind! ng, DE 26 49 029 Al reiates to an automatic winding machine for winding a wire-iike structure, such as an electric wire, onto a drum part, a coil or a reel, respectively, in a plurality of thin layers.

It is the object of the invention to overcome the disadvantages of the prior art, in particular to provide a laying arm for a device for helically winding a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic, onto a winding drum, wherein a higher level of automation can be attained, in the case of which a manual intervention by an operator is unnecessary as far as possible,

Thisobject issolved by meansof thefeaturesof claim 1.

According to this, a method according to the invention is provided for helically winding (traversing) a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic, onto a rotationally driven winding drum, such as a coil core. The winding drum is to be rotatably mounted, wherein the axis of rotation preferably remains stationary, so that the axially secured winding drum only performs a rotation about the axis of rotation or winding axis thereof. In regard to the winding method according to the invention, the winding material of the rotating winding drum is transferred via a guide, which is mounted for an axial back and forth laying movement. The guide preferably comprises a laying arm, through which or via which the winding material is guided until delivered to the winding drum. The laying arm is preferably mounted on a support, such as a rail structure, in a carriage-like manner. A rail-carriage mounting between the laying arm and the support can be embodied. The guide is set relative to the winding drum substantially trailing in accordance with the winding progress and the laying arm, wherein the support is preferably positioned so as to essentially follow the winding progress by means of a handling or adjusting device, such as a robot. According to the winding method according to the invention, aturning operation is performed when reaching an in particular predetermined, in particular a locally predetermined turning position asafunction of thesizeof the winding drum or of a sensed turning position.

The turning position can be predetermined by means of operator input of a specific position coordinate substantially relative to the winding drum into an in particular electronic open-ioop-control and/or closed-loop-control device, it can be calculated and corrected, if necessary, during the winding process by means of a corresponding regulation routine with the help of position sensors as a function of the winding operation. It turned out that the turning operation, regardless of for which radial winding position, succeeds reliably in consideration of a certain determined, in particular identical sequence of method steps, even in response to higher winding speeds, to attain acompacf and error-free winding result.

At the start of the turning operation, the guide, which arrives in a forth-laying movement to the turning position, is removed away from the winding drum in particular in a radial vertical direction, in particular lifted, in the vertical direction, so as to in particular completely and permanently free a contact end of the guide, which preferably roils on the winding drum and which bears against the winding drum or the most recently wound helical layer, in particular unrolls thereon, from the contact engagement thereof.

According to a first aspect of the invention, the turning operation is specified in that during or after the removal, the guide, in particular the support, is displaced forward in axial forth laying direction by an in particular predetermined axial subsequent-displacement-distance (starting at the turning position) forth laying movement direction relative to the winding drum, so as to in particular enable an traversing of the predetermined or sensed turning position, it is ensured in this way that the guide on the inner side of a radially extending sidewall flange of the winding drum is always in lateral placing contact with the side wall flange during the rotation of the winding drum. The forward displacement is to effect that even an only temporary loss of contact between the guide and the side wail flange of the winding drum is avoided. If the guide is to already be in contact with the side wail flange of the winding drum when reaching the turning position, the forward displacement either (only) effects a displacement of the support of the guide, which movably supports the laying arm, which can lead to an increase of a pretensioning force of a pretensioning device acting between the laying arm and the support, and/or possibly to a change of the angle of inclination of a longitudinal extension of the laying arm reiativeto the radial direction of the winding drum. In such a case, the laying arm is essentially supported on the support in a back and forth laying movement plane in a pivotable manner, so as to provide for different angles of inclination of the longitudinal extension of the laying arm relative to the winding drum, in particular to the side flange of the winding drum. According to the invention, a secure contacting of the guide with the side wall flange of the winding drum is attained with the forward displacement of the guide after reaching the turning position, which ensures a secure reference point and a stable axial support of the laying arm in response to the turning operation.

After the forward displacement, a position sensor can furthermore determine the position of the laying arm, in particular the free contact end thereof, in the room so as to define a local initialization, thus a zero position, of the laying arm, for the start of the construction of the next helical layer.

An operationally reliable automation of the winding material, in particular of a plastic tube, which acts in an inhomogeneous manner, can be attained with the measure according to the invention, on a winding drum, which is not perfectly symmetrical, even in response to high winding speeds of up to 100 m (meters) per minute and beyond.

In a preferred embodiment of the invention, the turning position is reached, when the laying arm of the guide, which extends to the winding drum, is in a direct contact with a side wall flange of the winding drum or when a contactor maker, which is arranged on a winding drum-side end of the laying arm triggers a contact signal. The contactor maker can be arranged at a winding drum-side end of the laying arm of the guide. The winding drum-side end is to be in the direct contact with the side flange of the winding drum during the turning operation, which is why the winding drum-side end has a contact area, which faces the side wall flange and on which the laying arm is to come into placing contact with the side wall flange. The placing contact can be embodied as bearing sliding contact or as rolling contact. The contactor maker is to generate and output a control signal, namely the turning operation triggering signal, preferably when reaching the turning position of the guide. The control signal serves the purpose of being transmitted to an electronic open-ioop-control and/or closed-ioop device, so that the regulating routine can trigger a regulation to change a certain regulation variable of the winding method. For the turning operation, the open-loop-confroi and/or ciosed-loop-control device can conclude the winding layer, which is already almost finished, and can begin the new winding layer on the completed winding layer. In response to the turning operation, a change in direction of the laying movement is associated with the guide. In the area of the placing contact area, the contactor maker in each case has an actuation projection, which protrudes from the respective placing contact area in back or forth laying movement direction, respectively, in an unactuated position, and is preferably movabiy, in particular movably mounted on the laying arm of the guide, so that in a release position, the respective actuation projection releases the respective placing contact area for the placing contact with the side wall flange. The contactor maker with its actuation projection, which protrudes in the back or forth laying movement direction, respectively, provides for a triggering of the control signal prior to reaching the outer position of the laying arm, which is limited in laying movement and which is only reached when the provided forward displacement according to invention in the forth laying movement direction, which is provided according to the first aspæt of the invention, has been carried out.

In a further development of the invention, the respective actuation projection, in the release position of the latter, is sunk in the laying arm of the guide, in a vertical view. The laying arm can in particular be limited by panels, which preferably encompass a completely closed transport space, in which a pivot axis of the actuation projection can disappear. The outer actuating side of the respective actuation projection is contour-adapted at an outer surface contour of the placing contact area, so that the outer actuating side is substantially located in the plane of the outer surface of the in particular plane contact area in the release position.

In apreferred embodiment of the invention, the actuation projection, in the unactuated position thereof, protrudes at least by one-half or an entire winding material thickness and maximally by two winding material thicknesses from the respective placing contact surface in back or forth laying movement direction, respectively. in a further development of the invention, the guide substantially remains in the turning position substantially without axial advance, at least with regard to the axial laying movement direction, during the radial removal.

The forward displacement becomes preferably only triggered when the removal of the guide away from the winding drum isat least largely concluded and/or when a predetermined winding distance or winding time has passed, after reaching the turning position. The winding distance or time can preferably be predetermined, for example by performing at least half a rotation of the winding drum and maximally one and a half rotations of the winding drum. in a particular embodiment of the invention, the lifting starting from the triggering signal, is to be concluded after about 0.8 rotations of the winding drum. After reaching the turning position, the forward displacement is to only be triggered, when about 0.8 rotations have occurred since reaching the turning position.

In afurther development of the Invention, the axial position of theguide relative to the turning position, in particular to the side wall flange of the winding drum, is monitored and optionally corrected in axial back and forth laying movement direction, after the forward displacement by means of an actual position measurement of theguide. The correction can serve the purpose of compensating axial impacts of the side wall flange without the loss of contact, in addition, the correction can aiso serve the purpose of monitoring and of readjusting it, if necessary, the zero position of theguide, in particular with regard to the carriage-rail mounting of the laying arm on a robot-side support.

For example, the position correction can be triggered only after a certain winding distance or time has passed, which is preferably in particular predetermined by performing maximally three-quarters or half a rotation of the winding drum. The forward displacement is to thus in particular be performed within a 0,4-fold rotation of the winding drum, A correction of the axial position can then be triggered, if necessary. in an alternative or combinable aspect of the invention, the forward displacement of the guide beyond the turning position can be forgone and only a position correction can be carried out, if necessary, after reaching the turning position. According to the invention, the guide is in particular moved away from the side wail flange instead of or after the axial displacement forward and, if necessary, the position correction in the axial backward laying moving direction, which is opposite the forth laying moving direction, relative to the winding drum, to in particular set the guide back to the turning position and/or to in particular cause it out of the placing contact with the side wall flange in a secure manner, and to position the guide without any contact to the side wall flange of thewindingdrum.

It is to preferably be ensured on the turning position that a contact between the guide and the sidewall flange is always ruled out even in the area of axial impacts in response to the complete circulation of the side wail flange. The move-back is to be triggered when a predetermined winding distance has been covered, which is preferably predetermined in particular in that maximally one or half a rotation of the winding drum has occurred since the conclusion of the removal, of the displacement forward or, where appropriate, of the correction or by the sequence of at least one or one and a half rotations since the turning position has been reached, preferably predetermined in advance.

In a preferred embodiment of the invention, the guide is moved substantially in a vertical direction towards the winding drum, in particular lowered, after the displacement forward and/or after the move-back so asto in particular bring a free contact end of theguide in contact, preferably in running or rolling or grinding contact, with the winding drum or an already wound w!nding layer. The guide can remain at the turning position substantially without axial advance during the radial approach. A forth laying movement, which triggers the turning position, is only triggerd when the approach! ng of theguideisat least largely concluded and/or when the contact end of the guide is brought into contact with the already wound winding layer. A forward laying movement, which leaves the turning position, is only triggered when the approaching of the guide is at least largely concluded and/or when the contact end of the guide is in contact with the already wound helical layer. The moving of the guide, which is directed to the winding drum, is preferably triggered after a predetermined wi ndi ng distance or time, which is preferably predetermined in that maximally half a rotation of the winding drum has occurred since the conclusion of the displacement forward or move-back or if at ieast one and a half rotations of the winding drum have occurred since reaching the turning position, preferably predetermined in advance.

In a further development of the invention, the guide is positioned relative to the winding drum after concluding the turning operation in response to the back and forth laying movement to the turning position according to a prescribed winding routine, according to which a winding drum-side contact end of the laying arm of the guide is in contact engagement with thewinding drum or the winding layer, which has been placed most recently, preferably in a rolling manner, and/or according to which the guide is advanced along aback and forth laying path between the turning positions adjacent to the respective side wail flange according to the axial winding increase on thewinding drum. The laying arm of the guide, which, as compared to a handling or adjusting device, such as a robot, is mounted in particular linearly in the axial direction, for example by means of a carriage-rail mounting, can thereby be readjusted according to a predetermined or regulated move-up path, in particular following the displacement forward. In response to the displacement forward and in response to the move-up, the laying arm can remain deflected with respect to a neutral position, so that the laying arm is pushed axially laterally against thewinding loop, which was placed onto thewinding drum most recently. An actuating force, which acts on the winding loop and which acts against a free lateral side of the winding loop, which was placed most recently, is preferably a function of the extent of the deflection of the laying arm from the neutral position, in which in particular no restoring force acts.

For the turning operation in response to removing the laying arm and in response to relinquishing contact, the laying arm is preferably located in a neutral position relative to the support, in which pretensioningforcesdo not act between thelayingarm and fhesupport and in which pretensioning forces are built up only in response to a relative displacement of the laying arm relative to the support out of the neutral position, which pretensioning forces push the laying arm and the support back into the neutral position thereof relative to one another. In response to the displacement forward, the laying arm can remain in the neutral position until the contact end of the laying arm comes to rest on the side wall flange. According to an displacement forward of the guide, which goes beyond the turning position, a restoring force is built up in the axial direction on the carriage-rail mounting, which pushes the laying arm against the winding loop, which was placed most recently. The extent of the displacement of the laying arm relative to the support out of the neutral position preferably corresponds to the displacement forward path of the guide after reaching the turning position. For the turning operation, the laying arm can be brought substantially into the neutral position in response to the correction and/or in response to the move-back, so that essentially no restoring forces act. In responseto moving the laying arm towardsthewinding drum, thelayingarm isin theneutra! position, whereby, as soon as the contact end of the laying arm comes into engagement contact with the winding layer, the laying arm is then deflected out of the neutral position in accordance with the winding progress through the respective winding loop, which was placed most recently, to generate the pretensioning force on the laying arm. in a further development of the invention, a winding basis the winding speed of the winding drum isadjusted asafunction of the i n particular axial actuation position of the guide relative to the winding drum in the axial course of the helical winding.

According to an independent winding method according to the invention, which can be combined with the above-defined method, the winding material of the rotating winding drum is transferred via a guide, which is mounted for an axial back and forth laying movement. The winding drum is preferably supported only for a rotational movement about an axis of rotation and is stationary in the axial direction. It is preferably the guide, which is mounted for a back and forth laying movement, which prompts the helical form of the winding material for a winding layer on the winding drum. The guide is preferably realized by means of a laying arm, which is held by an actuating device, such as a robot, and which is positioned parallel to the axis of rotation of the winding drum. The guide is positioned or moved relative to the winding drum, following the winding progress. According to the invention, the angular speed of the winding drum is varied in the axial course of the helical winding of a winding material layer, for example adjusted, in particular regulated, asafunction of the in particular axial and/or radial actuation position of the guide relative to the wind!ng drum, in particular to the drum core, according to a regulating routine. For this purpose, provision can be made for a open-loop-control and/or closed-ioop-controi device, which continuously or cyclically detects the actuation position of the guide relative to the winding drum, for example by means of a position sensor coupled thereto, and which monitors the speed as a function of the actuation position in accordance with the invention or in particular according to preset speed parameters. The angular speed can additionally be made dependent on the radial position of the winding layer, which is to be placed, relative to the drum core, thus on the number of the placed winding layers.

In response to laying the first (initial) winding layer, thus in response to creating the first winding directly on the drum core and, based on the axial contact with the side flange of the winding drum, the axial actuating position of the guide is preferably set to zero, “0”. The width of the winding drum, the axial distance of the inner sides of the side flanges of the winding drum, which are located opposite one another and which face one another, is input into the closed-loop-coniroi device in advance as winding drum-individual parameter. In response to the axial laying of the winding, thus in response to displacing the guide in the axial direction, the position of the guide is picked up by a sensor, such as a contact-free sensor (light sensor) or is determined by means of indirect defection (by means of passed or wound-up winding lengths), if the guide approaches a side flange, for example starting at a certain axial position, info the vicinity of the side flange, the regulating routine triggers a decrease of the winding speed, to carry out a so-called side flange or turning operation, in response to which the winding layer, which had not been laid completely until then, is closed, and a new winding layer located thereabvoe is to be started. For example, the turning operation can already start, before the last 4, 3 or 2 windings of the winding layer, which has not yet been placed completely, were placed. An increase or decrease of the angular speed as a function of the radial winding position can take place, when for examples or 4 layers of the “new” winding layer are placed.

In the preferred embodiment of the invention, the angular speed in response to creating a winding material layer, which can also bean in particular most recently wound helical layer, is changed relative to the winding drum, in particular in response to reaching a preadjusted axial position of the guide, in addition or in the alternative, the angular speed can be decreased in response to a loss of contact of a winding drum-side end of the guide with thewindingdrum or with a most recently wound helical layer, which is in particular determined by a open-loop-control and/or closed-loop-control device, and the angular speed can be increased again, in particular when the winding drum-side end makes contact with the winding drum or with the most recently wound helical layer again. In a preferred embodiment of the invention, the angular speed can be kept constant during the wind! ng and while maintaining the con tact. in a preferred embodiment of the method according to the invention, the angular speed of the winding drum is reduced in the course of the axial laying movement of the guide for an approaching of the guide to the side flange of the winding drum, preferably to a predetermined minimal angular speed, which can preferably be kept constant. The approaching movement of the guide can start, for example, when only four, three, two or one winding needsto be created to complete the entire winding layer. The time at which the approach procedure starts can be determined, for example, in that a longitudinal threshold value, which has already been wound, is exceeded, or a scanning sensor detects an axial initiating location. The angular speed for creating the first winding of thewinding layer, which is to be placed, thus of the first winding of the uppermost winding layer, which abuts directly on the side flange, can in particular remain reduced during the so-called side flange operation of the guide and when the guide moves away from the side flange of the winding drum, i.e. aiso in the case of windings, which follow the first winding. After fheturning process, the reduced angular speed can remain reduced for a plural ity of, and in particular one, two, three or four initial winding loops. After exceeding a certain axial position, for example after laying the third winding loop, the angular speed can be increased again to build up and to complete the winding layer along the axial direction of the winding drum, until the approaching procedure is triggered again, as it is described above. The angular speed for the laying movement of the guide to the opposite, remote side flange is preferably increased, in particular in an axial center field area, which is preferably predetermined, or which is specified by the angular speed control and/or regulation, preferably to the next approach point on the opposite side flange, such as an actuating edge area, so that the angular speed can reach an in particular predetermined maximum angular speed again. The central area can preferably be predetermined as a function of the axial dimension of the used winding drum, for example in a range of between 80 and 95% of the entire axial expansion between the opposite side flanges of the used winding drum. While the guide arm moves into the actuating edge area and the guide arm reaches the in particuiar predetermined axial actuation position, the angular speed is reduced for the next wall operation, preferably to the minimum angular speed.

In a further development of the invention, the winding drum is operated with at ieast two angular speeds, preferably two angular speeds, which are both run alternately by the winding drum. The first in particular maximum angular speed is preferably set to more than 50 rotations per minute, preferably 7Q rotations per minute, in particular substantially consistently, in response to the helical winding of thewinding material along the axial central actuating area of the winding drum. The second angular speed, preferably the minimum angular speed, is set to below 70 rotations per minute, in particuiar below 50 rotations per minute, substantially consistently, in response to reaching a predetermined axial actuating position of the guide relative to the winding drum. A transition between the first angular speed and the second angular speed is preferably realized by means of a constant or continuous angular speed change.

In a further development of the invention, the axial central actuating area is limited by two predetermined, winding drum-specific, axial actuation positions, in response to the exceeding of which in particular the above-mentioned side flange operation is initiated or ended, respectively. The limitation of the central actuating area, at which in particular the maximum angular speed is operated, has the result that the first angular speed is preferably set to above 80 rotations per minute in responseto the helical winding within the central actuating area Tests showed that angular speeds ot 90 rotations per minute or even more can beset. In responseto the helical winding of the winding material layer between the respective predetermined axial actuating position and theaxiai drum end, in particular theside flange of thewindingdrum, the second angular speed is preferably set to below 70 rotations per minute, it turned out that an optimal speed for the side flange operation is approximately 65 rotafionsper minute. in apreferred embodiment of the invention, the central actuating area takes up more than 50%, preferably between 60% and 80% or 90% of the entire axial total winding width between the two side flanges of thewindingdrum. The predetermined axial actuating position isdetermined to less than 20% of the axial total winding width between the side flange of the drum, in particular at an axial distance to the drum end. In addition or in the alternative, the speed can be reduced when leaving the central actuating area at the respective predetermined axial actuating position, but can also be increased, depending on the material properties of the respective winding material, which isto be wound. Both predetermined axial actuating positions are preferably placed symmetrically to the radial central axis at an identical axial distance to the respective axial drum end.

In apreferred embodiment of the invention, the angular speed of thewindingdrum is reduced for an approaching of the guide to the axial drum end, in particular before the last or the penultimate winding loop of the winding material layer has been placed, and/or after a position or distance sensor, such as a contactor maker, emits a triggering signal at a predetermined actuating position of the guide. In the alternative or in addition, the speed can be increased to the maximum speed in response to the axial removal of the guide from the side flange, in particular after at least one or two multi-layer winding loops are laid completely.

The invention furthermore relates to a device for the helical winding of a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic, onto a rotationally driven winding drum. The device according to the invention comprises a guide preferably comprising a laying arm, via which the winding material is transferred to the winding drum in response to an in particular linear back and forth laying movement of the laying arm in a winding manner, in addition to the laying arm, the guide can have a support, wherein thelaying arm and the support are coupled to one another via a carriage-rail mounting. The device according to the invention further has an adjusting device for moving, in particular for the vertical lifting and the axial displacement of the guide relative to the winding drum. The adjusting device is preferably formed by a robot, which can position the guide in ail three-dimensional directions. In addition, the device according to the invention has a open-loop-control and/or closed-loop-control device, which is coupled to the adjusting device and which positions the guide according to the above-mentioned method steps of the turning operation of the winding method according to the invention. It shall be clear that the control and regulating routine is to be designed to realize the method steps.

The invention furthermore relates to a device, which can be combined with the above-defined device or which is independent therefrom, for winding a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic, onto a rotationally driven, rotating winding drum, wherein the device can be designed according to the procedure of the method according to the invention. The device according to the invention has a guide, which transfers the winding material to the rotating winding drum in response to an in particular linear back and forth laying movement substantially along an axial direction of the drum in a helically winding manner. The device according to the invention is in particular designed to rotate the drum around the axis of rotation thereof at different angular speeds, wherein the axis of rotation of the winding drum is locked. The winding device according to the invention further has a winding drum rotary and an angular speed control and/or regulation, which is connected to the winding drum rotary drive. In the axial course of the winding of the respective winding material layer, the angular speed control and/or regulation adjusts the angular speed of the winding drum asafunction of theaxial and/or radial adjusting position of theguide, in particular of the winding drum-side end of the guide, relative to the winding drum. In the case of the winding layers, which are wound first, the angular velocity open-loop-control and/or closed-ioop-control for a plurality of winding layers can be operated at different angular speed. The angular speed is slower, while the angular speed is set to be higher for the winding of later winding layers on the radial outer area of the winding drum. The level of the decrease/increase of the angular speed can be made dependent on the extent of the asymmetry of the winding drum, which is to be wound. Winding drum-individual data of the speed open-loop control and/or of the closed-ioop control can in particular be input so as to adjust the corresponding optimal angular speed. Reference can be made hereby to empirical values. A differentiation can be made thereby between theaxial asymmetries, such as the axial side flange impact, and the radial asymmetries, such as the drum core impact. The inventors identified the radial asymmetrical impact on the drum coreas being particularly critical. in a preferred embodiment of theinvention, theangular speed open-loop-control and/or closed-loop-control is provided with a sensor, such as a contactor maker, for defecting at least one predetermined position of theguide. As specified above, this distance sensor or position sensor of the guide can trigger a zero setting at the beginning of the wind! ng layer, wherein the progress of the winding can be determined either directly, in particular by means of the sensor, or indirectly, viathe speed or the amount of the already wound-up winding material.

The distance sensor is preferably arranged and fastened to the guide, wherein in particuiar the distance sensor outputs a triggering signal in response to detecting at least one predetermined setting position, so that the angular speed open-loop control and/or ciosed-loop-control thereupon changes the angular speed. At least one predefined setting position is preferably defined when the contactor maker makes contact with an inner side of a side flange of the winding drum. For this purpose, the contactor maker preferably has a bracket or awheel along the edge, wherein a mounting axis of rotation of the contactor maker is pivoted away from aside flange, in particular in the axial direction, so that it can roll or run thereon in contact with the rotating side flange, in response to a further displacement of the guide, the contactor maker can be pivoted from a passive position into an active position, in which a triggering signal can be output to the angular speed open-loop-control or closed-ioop-control or directly to the rotary drive.

The device according to the invention for winding the strand-shaped winding material can be embodied in such away that the method steps of the method according to the invention are realized with the device according to the invention. The winding method according to the invention can also be designed in such away that the mode of operation of thewinding device according to the invention are realized according to the method.

In a preferred embodiment of the invention, a laying arm of the device for the helical winding can preferably be supported and positioned by an adjusting device, such as a robot, preferably according to a open-loop-control and/or closed-loop-control routine. The laying arm serves the purpose of guiding the strand or winding material to thewinding drum in a channeled manner and to transfer it to be wound, while the laying arm is moved back and forth in particular substantially transversely to its longitudinal extension and linearly between the axial ends, such as the sidewall flanges, of thewinding drum. The laying arm thereby follows the axial winding progress of the winding material, which is wound onto the winding drum, in particular in a gradual manner.

The laying arm has a winding drum-side end, which is in a contact, in particuiar unrolling contact, with the winding drum or with the winding layer, which is already wound thereon, across a large portion of the entire winding process, and on which a placing contact area, which faces the respective side flange of the wind!ng drum, is formed in each case, on which the laying arm comes into direct contact with one of the two side flanges in particular in response to performing a turning operation. The placing contact can be formed as direct sliding contact or rolling contact. The device according to the invention further has a distance sensor, such as a contactor maker, which is arranged on the winding-side end and which outputs a control signal, such as a turning operation triggering signal, at least in response to reaching at least a predefined winding position, at least a triggering position for the turning operation of the winding drum-side end. The control signal goes to an electronic open-ioop-control and/or closed-loop-controi device, whereby a regulation to change a certain regulation variable of the winding process can be triggered. The open-loop-controi and/or closed-ioop-controi device preferably performs a turn! ng operation, in responseto which the old winding layer is concluded and the new winding layer is begun on the old winding layer. A change in direction of the laying movement of the laying arm is accompanied with the turning operation. According to the invention, the distance sensor in each case has an actuation projection in the area of each contact area, which protrudes from the respective placing contact area in the direction of the back or forth laying movement, respectively, when in an unactuated position, and which is preferably mounted on the laying arm to be movable, in particular pivotable in such away that the respective actuating projection, in its release position, releases the respective contact area for the direct contact with the side wall flange. The inventors have found out that the positioning of the winding drum-side end and thus of the laying arm relative to the winding drum is essential for the turning or wail operation, which is difficult from the winding technology aspect, so as to be able to realize higher winding speeds of more than 80 m/min. in particular the timing, at which distance to theside wail flange of the wind! ng drum as well as when the turning operation is triggered and concluded, is significant to realize an error-free conclusion of the helical or winding layer and new formation of a solid winding layer base. The contactor maker comprising its actuation projection, which projects in the back or forth laying movement direction, respectively, realizes a triggering of the control signal prior to reaching the outer position of the laying arm, which limits in the laying movement and which is reached when the winding drum-side end of the laying arm is in contact with the side wail flange of the winding drum. The yielding, in particular rotationally movable actuation projection allows for the winding drum-side end to come into contact with the side wall flange.

In a further development of the invention, the respective actuation projection is sunk into the laying arm in a vertical view in its release position, in particular into a housing structure of the laying arm. The laying arm can comprise a preferably completely closed transport space, which is in particular limited by plates, in which a pivot axis of the actuating projection is arranged, and the respective actuation projection has disappeared when reaching the side flange wall. An actuating outer side of the actuating projection preferably comes into a grind! ng contact with the side flank wail, wherein in particular the actuating outer side of the respective actuating projection is substantially flat and level. The actuating outer side of the respective actuating projection is contour-adapted to an outer surface of the contact area, so that in the release position, the actuating outer side is substantially located in the plane of the outer surface of the in particular planar placing contact area so as to be free from projection.

In a preferred embodiment of the invention, the actuation projection, in the inactive position (neutral position) thereof, projects by at least a half or by an entire winding material thickness and maximally by two winding material thicknesses from the respective contact surface in back or forth laying movement direction, respectively. An optimized advancing triggering of the control signal can be attained in fhisway beforethe placing contact area of the laying arm comes into contact with the side wall flange. It shall be clear that the time period and/or the winding distance between triggering the control signal and establishing contact of the placing contact area can be adjusted in that a triggering of the control signal is changed only after exceeding an adjustable amplitude of movement of the actuating projection from the unactuated position thereof. in a further development of the invention, the laying arm has a winding material delivery opening on its winding drum-side end, on which thewinding material leaves the transport space of the laying arm, so as to subsequently be transferred to thewinding drum, in particular in an unguided or contact-free manner. The distance sensor on the laying arm is advantageously arranged closer to a substantially cylindrical drum core of thewindingdrum than thewinding material delivery, at which thewinding material leaves the laying arm in an ungulded manner under the exclusive influence of the force of gravity and the internal winding force of the winding material. The distance sensor is preferably arranged in the vertical direction below the winding material delivery, wherein in particular thewinding material runs past the components of the distance sensor to thewindingdrum in a contact-free manner. in a preferred embodiment of the invention, the laying arm according to the invention comprises a sword-shaped housing, which is preferably formed from two housing plates, which are arranged parallel to one another and which extend in the longitudinal direction of the laying arm and which limit a transport space of the laying arm, which extends from an actuator-side base section to the winding drum-side end of the laying arm. The winding material is guided through the transport space, which extends completely through the laying arm in the longitudinal direction, to a winding material delivery opening. The housing plates have in particular an outer surface, which preferably lies in a vertical plane. The placing contact area, at which the winding drum-side end comes into direct contact with the side wall flange of the winding drum, is embodied on an axial end section of the outer surface of the respective housing plate.

The placing contact area can deformed by an in particular removable wear plate, in particular of a material with lower friction, such as polyamide. The wear plate is preferably exchangeably arranged on, in particular screwed to, theaxial end section of the two housing plates.

In a further development of the Invention, the contactor maker has a pivot axis, which is mounted relative to the laying arm In a stationary manner. The pivot axis is rotatably mounted on the housing of the laying arm in the interior of the transport space. In every operating position of the actuating projection Inside the transport space of the laying arm, the pivot axis remains stationary. The pivot axis preferably extends substantially in the vertical direction, so that the respective actuation projection of the contactor maker is pivoted substantially in a horizontal plane.

In a preferred embodiment of the invention, an additional rotary movement sensor engages with the pivot axis of the contactor maker, so that the control signal can degenerated and output in particuiar after exceeding a predeterm I nod pivoting amplitude of movement of the respective actuation projection.

To generate the control signal, a pivoting movement transfer mechanism is in particular accommodated inside the transport space of the laying arm. The pivoting movement transfer mechanism serves the purpose of transferring the pivoting movement of the contactor maker away from thewinding drum-side end to the base-side end of the laying arm, preferably without the movement transfer being realized by means of conversion into an electronic signal. An electrical signal generator, which is preferably arranged inside or possibly outside of the transport space of the laying arm, and which generates and transfers the control signal by means of the transferred pivoting movement, can be arranged only at a distance from the winding drum-side end. The pivoting movement transfer mechanism is preferably realized by means of an angular gear, which transfers the pivoting movement of the actuating projection-side pivot axis of the contactor maker, which extends substantially in the vertical direction, to a transfer shaft, which extends in the longitudinal direction (horizontal direction) of the laying arm.

In a further development of the invention, the actuating projection-side pivot axis of the contactor maker, which in particuiar extends substantially in the vertical direction, is pretensioned in such away, in particuiar spring-pretensioned, that the actuating projection is always forced from the respective release position thereof into the unactuated neutral position. The transfer shaft is preferably at least divided into two parts, so that a pivot axis-side shaft section can be removed in a destruction-free manner from a shaft section, which is located at a distance from the pivot axis. The division into two parts serves for the modular exchange of the entire winding drum-side end of the laying arm, so as to be able to adapt the latter to winding materials of different thicknesses.

In a further development of the invention, the contactor maker has a bracket shape, which forms a closed ring structure. The bracket is preferably realized in an axially symmetrical manner. In the unactuated position of the contactor maker, the axis of symmetry of the ring structure in the unactuated position of the contactor maker coincides with the longitudinal direction of the laying arm. The two actuation projections are part of the bracket-shaped triangular structure. The triangular structure is preferably realized in an isosceles manner, wherein a corner area of the triangular bracket-shape, which is close to the respective actuation projection, is rounded. The same legs are arranged at an angle of less than 35° to one another, preferably approximately 30°. if shall be dear that the device according to the invention as well as the method according to the invention can be embodied according to the devices and methods as described in the filed German patent applications (10 2013 002 023.9, 10 2013 002 022.0, 10 2013 002 017.4, 10 2013 002 019.0 and 10 2013 002 020.4).

In a preferred embodiment of the device, the support can only be designed to form a contact area for fastening the adjusting device or a handling device, such as the robot. The support preferably has a rail for a rail-carriage arrangement. The winding material of the rotating winding drum istransferred in a winding manner viaawindingdrum-sideend of thelayingarm in responseto the axial, in particular linear, back and forth laying movement of the laying arm. The axial back and forth movement is preferably oriented linearly in a purely translatory manner and substantially parallel to the axis of rotation of the winding drum. The winding drum-side end in particular describes the axial linear back and forth laying path between the two opposite side flanges of the winding drum. Facing away from the winding drum, the laying arm has an accommodation for accepting the winding material, which leaves an extruding station in particular continuously. The acceptance can be formal for example by a star-shaped arrangement of a plurality, in particular four, free-running rollers. The accommodation can additionally have a support structure, on which for example electronic components, but also pneumatic damp! ng systems for mounting the laying arm can beheld.

The winding device according to the invention preferably has a laying arm mounting, which guides the laying arm in particular in axial laying direction relative to the support. The winding device according to the invention preferably has a restoring or pretensioning device, which generates a restoring or pretensioning force, which isin particular elastic, in particular directed substantially axially, and which reports to the laying arm, so as to push the laying arm laterally against the winding loop, which was placed onto the winding drum most recently, in responseto a deflection of the laying arm, which was in particular prompted by the axial growth of the winding layer on the winding drum, in particular out of the neutral position of the laying arm relative to the support.

The restoring device and the laying arm mounting pretension the laying arm in such away that the latter is axially supported on thewinding, in particular thewinding loop, which was placed most recently so as to push in particular on the winding drum-side end thereof. The larger the deflection of the laying arm relative to the support, the stronger the restoring force, which causes the axial pretensioning

In the neutral position, a restoring force preferably does not act on the laying arm and thus on the winding loop, which was placed most recently. The restoring force generated by the restoring device preferably acts continuously on the winding loop, which was placed most recently, during the entire back and forth laying movement of the laying arm. The restoring force and thus the continuous axial pretensioning of the winding drum-side end of the laying arm against the winding loop press the winding loop, which was placed most recently, axially against the directly adjacent winding loop, whereby a compact, gap-free winding structure is created. The resilience in the laying direction realized by the laying arm mounting, combined wit the elastic restoring pretensioning opposite the laying direction allows a change in position of the laying arm, which is prompted by the winding on the winding drum, which is built up gradually, in response to the winding according to the invention, the laying arm does not perform an actively determined, in particular regulated adjusting procedure, but constantly adapts flexibly to special geometric features and material-specific features of the winding. In a further development of the invention, a particularly fail-safe automation of the winding in responset© high conveying and wind! ng speeds of up to 100 m/min and beyond can be attained. In addition to the translatory flexible mounting in the laying direction, the laying arm can aiso beflexibly mounted in a vertical direction.

The laying arm mounting can preferably allow a purely translatory adjustment of the support-side end of the laying arm and, if necessary, a purely translatory vertical movement of the support-side end of the laying arm. If necessary, the laying arm could additionally perform a pivoting movement of the laying arm around the support-side end of the laying arm by means of a corresponding support-side laying arm pivoting, wherein a pivoting movement can be allowed in an axial plane as well as in a vertical plane. This laying arm pivoting mounting must allow a pivoting amplitude of only a few degrees, in particular smaller than 20°. The longer the longitudinal expansion of the laying arm, the smaller the pivoting mounting amplitude has to be designed in thevertical direction and horizontal direction.

In a preferred embodiment of the invention, a winding drum-side end of the laying arm, which can for exampiebe embodied as free-running engagement wheel, isembodied in such awaythat thewinding drum-side end comes info an in particular constant lateral contact with a lateral side, which is free at least in circumferential sections, of the winding loop, which was placed most recently, due to the restoring force in response to the axial back and forth laying movement, in particular during the entire back and forth pivoting movement, so that in particuiar the laying arm is deflected in the axial laying direction, depending on axial deflection out of the neutral position, for example gradually by the axial expansion of a winding loop. According to the axiai deflection, a restoring force, which is reported to the lateral side of the winding loop, which was placed most recently, via the winding drum-side end of thelayingarm, is generated by means of the restoring device.

In a preferred embodiment of the invention, the restoring device comprises a suspension, which can in particular decontrolled or adjusted by the open-loop-control and/or ciosed-loop-control device, which, in response to a corresponding deflection of the laying arm out of the neutral position into a deflecting position, generates, in particular calculates, an elastic restoring force. If shall be clear that a controllable suspension can already generate a restoring force, without being associated with adeflection of the laying arm out of a neutral position. The restoring force is oriented in such away that the effective direction thereof is located parallel to the axial laying direction, in particular parallel to the axis of rotation of thewinding drum. So that the restoring device presses the winding drum-side end against the winding loop, which was placed most recently, the effective di recti on of the restoring force is opposite to the laying di recti on.

The restoring force preferably only serves to pretension the laying arm in the axial direction against the winding and to support it thereon. To restore the laying arm reiativeto the support again is preferably realized by an adjusting device, such as a robot, which holds the support, and which guides the support relative to the deflected laying arm when a deflection threshold or a maximum restoring/pretension!ng force is exceeded.

In a preferred embodiment of the invention, the restoring device is formed by a pneumatic actuator, in particuiar by a pair of pneumatic actuators, one of the actuators of which is responsible for generating the restoring force in each case in an axiai laying direction. The pneumatic actuator can be coupled to a open-ioop-control and/or closed-loop-control device to receive operational or winding-related additional control signals to actively increase or decrease the restoring force and thus the pretensioning force as compared to the amount, which occurs in any event, according to the axial deflection.

The restoring device is preferably connected to a open-loop-controi and/or ciosed-loop-control device, so that the restoring force and thus the pretensioning force is kept substantially within a specified threshold range, in particular constant, during thewinding.

In responseto the winding, the restoring force is generated gradually due to the resilient laying arm mounting. If a threshold of a threshold range is exceeded, the restoring force can be restored gradually, without allowing the restoring foree/prefensioning to disappear, so that the restoring force always remains within the predetermined boundaries. A lowering of the restoring force is realized by a correspond!ng tracking of the support relative to the laying arm.

In a further development of the invention, the restoring device has an open-loop-control and/or closed-loop-control device for adjusting the restoring force/pretensioning for example by adjusting the spring characteristic of the restoring device and/or a control for adjusting the deflection amplitude of the laying arm. The respective open-ioop-control and/or closed-ioop-controi device can be coupled to a sensor, which detects the deflection width of the laying arm out of the neutral position and reports it to the open-loop-confrol and/or closed-ioop-controi device, such as a microcomputer. For example in the case of a constant spring characteristic of the restoring device, the microcomputer can determine a target deflection, according to which a regulating process is initiated.

In a further development of the invention, the restoring force can be adjusted. This is realized, for example, in that the support is guided relative to the laying arm, which is moved up, supported on the placed winding, in particular on the winding loop, which was placed most recently. For this purpose, the winding device according to the invention in particular comprises a handling or adjusting device, such as at least two, preferably three movement axes, preferably in a vertical movement axis and in a horizontal movement axis in laying direction of thelaying arm, in particular parallel to the axis of rotation of the winding drum. The adjusting device positions the support relative to the laying arm, which is supported on the placed winding, whereby the elastic restoring force, which acts between the laying arm and the support, can be increased or decreased. Provision is preferably made for an open-loop-controi and/or closed-ioop-controi device for the winding device, which adjusts the restoring force, and which triggers a move-up of the support with respect to the laying arm, which is displaced by the winding increase, by means of the adjusting device only when the laying arm has exceeded a predetermined deflection path or adeflection threshold along the support.

The winding device preferably comprises a move-up device, according to which the support is moved up in theaxiai displacement mounting direction after the elastic restoring force build-up according to the increase of the winding in the axial direction. For this purpose, the move-up device has the adjusting device, which holds the support.

In apreferred embodiment of the invention, the laying arm mounting is formed by means of a carriage-rail arrangement. The carriage-rail arrangement ensures a linear guide of the laying arm relative to the support, which is forced substantially parallel to the axis of rotation of the winding drum. The rail is embodied on the support side, while the carriage is realized on the laying arm side. It shall be clear that the rail can also be arranged on the laying arm side, while the carriage is located on the support side. The restoring device is connected between the carriage and the rail, so that the corresponding force transfer locations of the restoring device are arranged on the carriage and on the rail. The laying sword of the laying arm is fastened to the carriage, while the handling device engages with the rail of the support to provide the readjusting of the support with respect to the laying arm.

In a preferred embodiment of the invention, the winding drum-side end is mounted in such a way that the winding drum-side end is advanced along the laying path, at least in the case of a portion, preferably for the totality of the back and forth laying movement, in particular to the laying direction change by forming a substantially axial lateral contact with a free lateral side of the winding loop, which was wound onto the winding drum most recently, through the axially expanding winding layer, A correctively flexible behavior of the laying arm, which is required for the automation, is realized in this way, which already comes very close to the manual manipulation by an experienced operator, whereby in particular geometric imbalances of the winding drum or of the winding do not impact an automated winding process. The winding drum-side end is preferably formed by a wheel, which is mounted on the laying arm in a freely rotatable manner, from which at least a portion of the lateral area projects beyond the laying arm so as to be able to come into contact with the lateral side, which is still free, of the winding loop, which was wound most recently, and which is rotationaily driven in the direction of rotation only by the winding drum or by the winding material, which is already located on the winding drum. The wheel is entrained in the laying direction by means of the winding layer, which grows steadily in axial direction, along the laying path, and is axially displaced. The wheel thereby roils on the winding drum or on the winding layer, which has already been placed completely, at least under the impact of the weight of the laying arm. A preferred embodiment of the invention furthermore relates to a positioning or release device, which, at least in response to the laying movement close to the side flange of thewinding drum, positions the laying arm at a positioning angle, which is “positive” to the horizontal radial extension of the one side flange, so as to be inclined away from the one side flange, and pivots the laying arm into a "negative” positioning angle so as to be inclined away from the other side flange during the course of the back and forth laying movement towards the opposite side flange. The adjusting device is preferably formed by the handling device, such as the adjusting robot, which positions the support in order to carry out the desired pivoting movement about the winding loop contact. The pivot axis of the pivoting movement is preferably located in the area of the winding drum-side end of the laying arm. The pivoting location can move along the back and forth laying path, it is sufficient to adjust a release angle of between 1° and 20°. According to the release angle, the rotatable laying direction of the laying arm, which is defined by the laying arm mounting, is aiso inclined with respect to the axiai direction, wherein the angle of inclination on the axial ends of the back and forth laying movement is thus largest and decreases during the course of the back and forth laying movement, as does the release angle, and disappears approximately at half the laying path and subsequently increases again, in particuiar gradually.

In a preferred embodiment of the invention, provision is made for the operational positioning of thelayingarm in particular in response to a change in direction of the back and forth laying for a laying arm adjusting device for the in particular vertical positioning of the laying arm relative to the winding drum. The laying arm adjusting device cooperates with a distance sensor to detect at ieast one predetermined position of the laying arm along the laying path, wherein, when the at least on predefined position is reached, the distance sensor prompts the laying arm adjusting device, if applicable, to lift the laying arm away from thewinding drum or from the winding layer, which has already been placed thereon, by at ieast approximately half the thickness of thewinding material, preferably by approximately one winding material thickness or by more than one winding material thickness, and maximally by twice the winding material thickness. The laying arm adjusting device can have an in particular vertical pivot bearing for the laying arm, wherein a pivot axis of the laying arm is arranged on the support side. The pivot bearing can for example be realized in that a winding drum-side laying arm sword can be pivoted in the vertical direction relative to the support-side laying arm base. The laying arm adjusting device can furthermore have a lifter for in particular linearly lifting the pivot axis in the vertical direction, wherein the lifter is for exampie formed by the handling device, such as the adjusting robot, which accesses the support to lift the support, together with the laying arm pivot axis, vertically linearly. To entrain the pivotable winding drum-side end in response to the lifting, the pivot bearing has a bearing stop, which limits a lowering of the winding drum-side end of the laying arm. On the one hand, the pivot bearing allows for a flexible contact sequence of thewinding drum-side end on thewinding layer, which has already been placed, and thus a free contour following of the winding layer, which has already been placed, and the radial imbalances thereof. On the other hand, the bearing stop limits a lowering of the winding drum-side end based on the bearing on the winding layer by maximally half a winding material thickness, should the wind!ng drum-side end reach between two placed adjacent winding loops.

In a preferred embodiment of the invention, a winding material brake, which provides the winding material with a brake force prior to reaching the winding drum, is arranged on the laying arm, so as to pretension the winding material to tension. Operationally, the brake force can in particular beset by means of an open-loop control and/or closed-loop control.

In the method according to the invention, the winding material is transferred to the rotating winding drum by means of a back and forth laying movement of the laying arm relative to a support. The laying arm is mounted in the laying direction so as to be guided relative to a support. In response to deflection of the laying arm out of an installation position relative to the support, a restoring force is generated, which Is directed in theaxiai laying direction and which acts against the winding, which is placed onto the winding drum.

The method according to the invention is preferably defined by means of the above-mentioned operational and/or functional aspects of the winding device according to the invention.

In apreferred embodiment of the invention, the device for winding the strand-shaped winding material has a laying arm, on which the winding material is transferred to the rotating winding drum in response to an in particular linear back and forth laying movement of the laying arm. The back and forth laying movement of the laying arm is preferably limited by the side wail flanges of the winding drum. The direction of the back and forth laying movement can be located predominantly parallel and/or slightly inclined to the axial direction. The winding device can have an active laying arm adjusting device for vertically positioning the laying arm relative to the winding drum, which can in particular Hit and lower the laying arm only in the vertical direction. The winding device comprises a distance sensor for detecting at least one predetermined position of the laying arm, wherein, when reaching the at least one position, the distance sensor preferably prompts the laying arm adjusting device via an open-ioop control and/or closed-loop control to remove the laying arm from the winding drum or from the winding, which was already placed thereon, in particular to lift it in response to an exclusive vertical movement, by approximately at least half athickness of the winding material, preferably by at least approximately one winding material thickness, and by maximally twice the winding material thickness. In some cases, a lifting of more than twice or three times the winding material thickness, in particular empirically by more than 30 mm, is necessary. The vertical lifting of the laying arm, in particular of the winding drum-side end, for the change in direction of the back and forth laying movement shall be limited insofar as the winding drum-side end is to be entrained by the winding loop in substantially axial laying movement direction after laying the first winding loop of the new winding layer, so as to drive the laying arm for the back and forth laying movement.

The laying arm adjusting device provides in particular an exclusively vertical lifting movement to initiate the change in direction of the back and forth movement, wherein the laying arm adjusting device returns the laying arm to the extent that the winding drum-side end in particular comes into a radial contact with the concluded winding layer either in a rolling or sliding manner after the first winding ioop of the new winding layer has come into lateral engagement with the lifted winding drum-side end of the laying arm.

In a preferred embodiment of theinvention, thedistance sensor isarranged on a winding drum-side end of the laying arm. The distance sensor is preferably a contactor maker, which then outputs an electrical control signal in particular to a open-loop control and/or closed-loop control or directly to the laying arm adjusting device, when the laying arm, in particular the winding drum-side end thereof, reaches the at least one predefined position. The predefined position preferably corresponds to the end of the back and forth laying movement. When the contactor maker initiates contact with an inner side of a side flange of thewindingdrum, the at least one predefined position is preferably defined. In the alternative, the end of the back and forth movement can also go along even without a structural contact with the side flange of the winding drum, for example by reaching a certain minimum distance of the winding drum-side end to the side flange, which can for example be between approximately twice the winding material thickness or approximately one winding material thickness or less. in a preferred embodiment of the invention, the distance sensor has a wheel, which is mounted in a freely rotatable manner, the bearing axis of rotation of which can predominantly in particular be pivoted in the axial direction away from the side flange of the winding drum, whereby the triggering of the electrical control signal can be attained. The wheel of the distance sensor is mounted in a rotatable manner such that when it can unroll on the rotating side flange when it is in contact therewith and that, in responset© afurther displacement of the laying arm in the axial direction, it can be pivoted from a passive position into an active position, in which the electrical control signal is reported to the laying arm adjusting device via a open-loop control and/or closed-loop control, If applicable.

On the winding drum-side end of the laying arm in an area of a 12 o'clock position with respect to thewindingdrum, in particular under the impact of thewelght of the laying arm, the wheel of the distance sensor, which is mounted in a freely rotatable manner, preferably abuts on the winding drum or on an already laid winding layer in a substantially tangential manner. in a further development of the invention, the winding drum-side end of the laying arm is embodied to be in a constant lateral contact with a free lateral side of the winding loop, which was most recently placed onto the winding drum, in response to the back and forth laying movement, in particular at least in response to reaching the predetermined position. The winding drum-side end loses the contact to the winding layer in response to the removal from the winding and remains in the contact-free position until the winding drum-side end is entrained by forming the lateral contact with the free lateral side of the new winding loop, which was placed most recently, tor beginning the back and forth laying movement after the change in direction.

In a preferred embodiment of the invention, the laying arm adjusting device has a pivot bearing for pivoting a winding drum-side end of the laying arm, in particuiar only in a vertical plane. Thepivot bearing allows for a relative pivoting movement between the laying sword of thelaying arm and the laying arm base, which, in turn, is mounted on the support of thewinding device so as to be movable via the laying arm mounting, in particular linearly, substantially along the axial direction of the winding drum. The handling device, such as the adjusting robot, which is responsible for the vertical movement for lifting the pivot axis of thepivot bearing engages with the support. The handling device can aiso be responsible to move up the support in the di recti on of the back and forth laying movement, so that the support can follow the laying arm, which leads by means of the axial winding increase.

The laying arm adjusting device preferably has a lifter for the in particular linear lifting and/or lowering of the pivot axis of the pivot bearing, wherein the lifter can be realized in a component union by means of the handling device, such as the adjusting robot. The laying arm adjusting device can furthermore have a damp! ng device for damp! ng the pivoting movement.

In a further development of the invention, thepivot bearing allows for the winding drum-side end of the laying arm to bear on the winding drum or on a winding layer, which has already been placed, under the impact of the weight. The laying arm adjusting device, in particuiar the pivot bearing, can comprise a bearing stop, in particuiar as lower pivot limitation for limiting the vertical movability of the laying arm to thewinding drum. When thewinding drum-side end bears on the winding drum or on the winding layer, which has been placed most recently, the bearing stop is positioned in such a way that a free approaching movement of the winding drum-side end, which is In particular only damped, to the winding drum of maximally one winding material thickness, preferably maximally a fourth of thewinding material thickness, is permitted. In the alternative or in addition, the bearing stop can serve the purpose of entraining thelayingarm, in particular the laying sword, to remove the winding drum-side end away from thewinding drum or away from thewinding layer.

In a preferred embodiment of the invention, the winding device according to the invention comprises a laying arm mounting, which guides the laying arm in a laying direction, which can be rotated along the laying path, in particular depending on the axiai position, relative to the support, in particularly linearly, and a restoring or pretensioning device, which provides a restoring or prefensioning force to the laying arm in response to deflection of the laying arm in the laying direction relative to the support, so as to push the laying arm laterally, substantially axially against a winding loop, which was most recently placed onto the winding drum. The laying arm mounting can have a carriage-rail arrangement, according to which thelayingarm is guided linearly in the laying direction relative to the support. The axial direction is defined by the axis of rotation of the winding drum. The rotatable laying direction can be located parallel with respect to the axial direction, in particular as a function of the position of the laying arm along the laying path and/or can be inclined thereto to create an release angle of the laying arm in particular of less than 20° with respect to the horizontal radial extension of the side flange of the winding drum. The carriage is embodied on the laying arm side, wherein the rail is realized on the support side. A handling device, such as an adjusting robot, moves up the support so as to follow the laying arm, and serves the purpose of reducing the increasing deflection of thelaying arm, which is prompted by the axial growth of the winding layer and which always passes so as to lead with respect to the support, which moves up. The restoring force serves the purpose of continuously pushing the laying arm against the winding loop, which was placed most recently and to maintain a prefensioning against the winding loop and thus the winding loop contact in particular when the handling device moves up the support so as to follow the laying arm. The support may only move up to the extent that a sufficient pretensioning force still remains on the laying arm against the winding loop, which was placed most recently. The higher the deflection of the laying arm relative to the support, the stronger the restoring force of the restoring device acts. An optimally compact, tight arrangement of winding loop to winding loop is realized by meansof this aspect of the invention.

In a preferred embodiment of the invention, the winding drum-side end is mounted in such a way that the winding drum-side end is driven forward along the laying path, at least in the case of a portion, preferably for the totality of the back and forth laying movement, in particular to the laying direction changeby forming a substantially axial lateral contact with a free lateral side of the winding loop, which was wound onto thewindingdrum most recently, through the axially expanding winding layer. A correctively flexible behavior of thelaying arm, which is required for the automation, is realized in this way, which already comes very close to the manual manipulation by an experienced operator, whereby in particular geometric imbalances of the winding drum or of the winding do not impact an automated winding process. The winding drum-side end is preferably formed by a wheel, which is mounted on the laying arm in a freely rotatable manner, from which at least a portion of the lateral area projects beyond the laying arm so as to be able to come into contact with the lateral side, which is still free, of the winding loop, which was wound most recently, and which is rotationally driven in the direction of rotation only by the winding drum or by the winding material, which is already located on the winding drum. The wheel is entrained in the laying direction by means of the winding layer, which grows steadily in axial direction, along the laying path, and is axially displaced. The wheel thereby rolls on the winding drum or on the winding layer, which has already been placed completely, at least under the impact of thewelght of the laying arm. A preferred embodiment of the invention furthermore relates to a positioning or release device, which, at least in response to the laying movement close to the side flange of thewinding drum, positions the laying arm at a positioning angle, which is “positive” to the horizontal radial extension of the one side flange, so as to be inclined away from the one side flange, and pivots the laying arm into a "negative” positioning angle so as to be inclined away from the other side flange during the course of the back and forth laying movement towards the opposite side flange. The adjusting device is preferably formed by the handling device, such as the adjusting robot, which positions the support in order to carry out the desired pivoting movement about the winding loop contact. The pivot axis of the pivoting movement is preferably located in the area of the winding drum-side end of the laying arm. The pivoting location can move along the back and forth laying path, it is sufficient to adjust a release angle of between 1° and 20°. According to the release angle, the rotatable laying direction of the laying arm, which is defined by the laying arm mounting, is aiso inclined with respect to the axial direction, wherein the angle of inclination on theaxial ends of the back and forth laying movement is thus largest and decreases during the course of the back and forth laying movement, as does the release angle, and disappears approximately at half the laying path and subsequently increases again, in particular gradually.

In a preferred embodiment of the invention, a winding material brake, which provides the winding material with a brake force prior to reaching the winding drum, is arranged on the laying arm, so as to pretension the winding material to tension. Operationally, the brake force can in particular be adjusted by means of an open-loop control and/or closed-loop control.

In thecaseof thecl aimed method for winding the strand-shaped winding material, thewinding material is transferred via the laying arm of the rotating winding drum, which is mounted for the back and forth laying movement. At least one predetermined position of the laying arm is predetermined for a change in direction of the back and forth laying movement, wherein the reaching of the at least one position is determined by means of sensors. When reaching the at least one predefined position of the laying arm, the laying arm is preferably removed, in particular lifted, from the winding drum or from the winding layer, which has already been placed thereon, preferably by means of an open-loop control and/or closed-loop control by approximately at least half athicknessof thewinding material, preferably by approximately one winding material thickness, and maximally by twicethewinding material thickness.

The predetermined position for the change in direction of the back and forth laying movement is preferably reached when the winding drum-side end of the laying arm, which is in continuous contact, in particuiar in response to displacement of the laying arm along the laying path, with the winding drum and/or the winding layer, which has already been placed, contacts an inner side of a side flange of the winding drum or at the latest when it is at a distance of maximally twice the winding material thickness, preferably of approximately one winding material thickness, to the inner side of the respective side flange.

Further preferred embodiments are specified in thesubciaims.

Thewinding device in general according to the invention is provided with reference numeral 1 in Figure 1. The winding device 1 serves the purpose of wind! ng a plastic tube 3, such asaso-calied cable protection tube, which is continuously extruded by an extruding station, which is not illustrated in detail, onto a winding drum 5, wherein a winding, which is as even as possible, is to be attained without space between the individual winding loops 17 and with substantially constant winding gradient of aplastic tube width per rotation, as it is illustrated for example in Figures 1 to 4b.

The winding drum 5 comprises a substantially cylindrical drum core 7, to both axial ends of which a lateral side flange 11a, 11b, which extends in the radial direction, is in each case fastened. Concentrically to the rotational symmetry of thewindingdrum 5, an axis of rotation 13 of thewindingdrum Sismounted in a stationary manner (with respect to a reference bottom B, on which the winding device 1 stands), about which thewindingdrum 5 rotates to perform the winding process. The axis of rotation 13 defines an axial direction, to which reference will aiso be made below to define movements of movable components of thewinding device 1.

For economic reasons, the standardized winding drum 5 is often made of wood, wherein the drum core 7 as well as the side flanges 11a, 11b can differ slightly, but not negligibly, from an ideally symmetrical shape. The cylindrical drum core 7 can have radial runouts, while the side flanges 11a, 11b can form axial imbalances. Winding drums 5 of a different material, such as plastic, often also differ from an ideally symmetrical rotational shape by chance or for reasons of production.

As illustrated in Figure 1, the extruded plastic tube 3 is already wound around the drum core 7 by more than theaxial half of thewindingdrum 5 in an initial winding layer. Thewinding loop, which was just applied to the drum core 7 most recently, will be provided with reference numeral 17 below. Until the next winding loop is placed completely circumferentially and abuts laterally, the winding loop 17 has a free axial lateral side 18 on the peripheral portion, to which reference shall be made below in particular at an approximately 12 o'clock circumferential position (contact with the engaging wheel 43).

The plastic tube 3 is extruded in a continuously cylindrical manner along its extension and can have an outer diameter of between 5 mm and 30 mm or 40 mm. The thickness of the plastic tube 3 can be between approximately 0%and 60% of the outer tube radius. The plastic tube 3 is format continuously in an extruding station (not illustrated) and reaches via a cooling line (water bath) into thewinding device 1, upstream of which a plastictube (3) buffer system (not illustrated) can be connected, by means of which different conveying speeds of the plastic tube 3 in the longitudinal direction thereof are to be compensated in response to the extrusion process as well as in response to the winding. The non-iliustrated buffer system can for example be embodied as averticai pendulum, which can compensate a speed of thewinding device 1, which is too low/too high as compared to the extrusion device by means of the vertical di spl aceabi i I ty of adeflection wheel, in that the deflection wheel assumes a higher/lower vertical position. A buffer sætion can be reached in this way for the extruded plastic tube (3) for a continuous production process before it reaches into thewinding device 1.

Thewinding device 1 according to the invention substantially consists of four main components, namely a support 23, a restoring device 61, an adjusting robot 71, which is only suggested in Figures, and a laying arm 27 according to the invention.

The laying arm 27 according to the invention has the shape as, for example, a chainsaw comprising a laying arm base 28 (actuator/motor base) as well as a laying sword 29, which extends from the laying arm base 28 substantially in the horizontal direction to the winding drum 5 and which directly or indirectly touches the latter. On its front side, which faces away from the winding drum 5, the laying arm base 28 has an accommodation 21 (Figures 6, 9 and 10) for accepting the plastic tube 3, which in particular continuously leaves an extruding station. The accommodation 21 comprises runner pairs 25, which are arranged in a star-shaped manner and which limit a threading opening to ensure a horizontally and vertically guided threading of the plastic tube 3 into the laying arm 27. The laying arm base 28 is mainly formed by means of a profile support 57, which is comprised of a plurality of support plates, which are jointed together. Functional components of the winding device 1, such as a microcomputer, actuators, etc., can be attached to the support plates.

The support 23 holds the laying arm 27 in a movable manner and, in the illustrated embodiment, has a rail 51, to which a gripper arm of the adjusting robot 71 is fastened. The rail 51 cooperates with a carriage 53 of the laying arm base 28 in such a way that the laying arm 27 can be moved back and forth along the linear carriage path.

The laying sword 29 mainly extends in a horizontal direction, approximately perpendicular to the axial direction 13, away from the laying arm base 28 to the winding drum 5, wherein the laying arm 27 is dimensioned in such away that, in the longitudinal direction, it projects beyond the drum core 7 (approximately to the axial center thereof) (viewed in the lifting direction A).

The laying sword 29 has two vertical guides and holding plates 31a, 31b, which are arranged parallel to one another. A guide gap for forming a transport space 32 tor the plastic tube 3 is formed between the two holding and guide plates 31a, 31b, which, in the substantially horizontal extension thereof, have a substantially constant vertical width. So that the plastic tube 3 can glide securely from the accommodation 21 along the laying arm 27 between the holding and guide plates 31a, 31b, guide rollers can be rotatably mounted in the guide gap on the holding and guide plates 31a, 31b and can form a local ion-defined guide duct through the transport space 32, A winding material delivery 34, in particular in the form of a pair of delivery rollers 35 comprising horizontal axes of rotation, which ensure aguided delivery of the plastic tube 3 from thewinding drum-side end 33 of the laying arm 27 towardsthewinding drum 5, is still mounted in the transport space 34 on a winding drum-side end 33 of thelaying arm 27. An arm-shaped or strut-shaped supporting structure 30 extends between the laying arm base 28 and the winding drum-side end 33, The supporting structure 30 can be limited laterally by means of vertically arranged plates and can limit the transport space 32, A plurality of guide rollers for the guide-through of thewinding material are rotatably mounted on the supporting structure 30. A distance sensor 36 in a first embodiment of a contactor maker 37 is positioned on an upper sideoi thewindingdrum-sideend 33. Thecontactor maker 37 comprises a contact wheel, which is mounted in a freely rotatable manner and the axis of rotation of which is arranged vertically. A different distance sensor, which is known from the prior art, can be used as well. The contact wheel has a passive operating state in the course of the laying movement W of the laying arm 27 between the left side flange 11b and the opposite right side flange 11a, in the case of which the axis of rotation is located in a guide gap of the laying sword 29. Preferably as soon as the contact wheel of the contactor maker 37 comes into engagement with the radial inner side 41 of the respective side flange 11a, 11b, the contact wheel, in particular the vertical axis of rotation thereof, is deflected in the axial direction, because the contact wheel axially projects on the winding drum-side end 33 of the laying arm 27 in both axial directions and is pivotably mounted on the laying arm 27 for an axial deflection, in response to the axial deflection of the contact wheel, thecontactor maker 37 outputs an electrical contact signal to a open-loop-control and/or closed-ioop-controi device, which is not illustrated in detail, which processes the contact signal for the further winding operation of the winding device 1. The triggering of the electrical contact signal can be initiated and transferred immediately after moving the contact wheel from the unacfuated center position thereof or with a path-dependent delay after reaching a predetermined pivot amplitude of movement. A placing contact area 38, on which the winding drum-side end 33 of the laying arm can come into a sliding contact with the side flange wall 11a, 11b of the winding drum 5, is embodied on thewinding drum-side end 33 of the laying arm 27. For thispurpose, thepivot bearing 39 of the distance sensor 34 is designed in such awaythat the contact wheel of the contactor maker 37 is pivoted away at least to the height of the outer side of the respective placing contact area 38, so that the actuating projection of the contact wheel is sunk completely in the lateral direction and the respective placing contact area 38 is released. An alternative distance sensor embodiment will be described beiow.

On the underside of the winding drum-side end 33 located opposite the upper side, an engaging wheel 43 is mounted in a stationary manner so asto be freely rotatable on the laying arm 27, the axis of rotation of which is located substantially horizontally parallel to the axis of rotation 13 of the winding drum 5. The running surface of the engaging wheel 43 is in direct roiling contact with the driven drum core 7 or with a winding layer, which has already been placed. A freely accessible side area of the engaging wheel 43 abuts on the axial lateral side 18 of the winding loop 17, which was placed most recently, with a predominantly axial pressure pretensioning contact in response to thewinding.

The axial width of the running surface of the engaging wheel 43 is dimensioned in such away that it is larger than half of the outer diameter of the plastic tube 3, but smaller than the outer diameter of the plastic tube 3.

The laying arm 27 is mounted in a vertically pivotable manner via a support-side (23) pivot bearing, which is not illustrated in more detail, wherein a support-side pivot axis S runs horizontally, at least asafunction of the laying path position, parallel to the axis of rotation 13 of the winding drum 5. To control the pivoting movement of the laying arm 27 in a vertical plane, provision is made for a damping unit 45, which is fastened to the support 23 on the one side and, on the other side, to a projection 47 on the upper side of the laying sword 29. The damping unit 45 ensures a damped pivoting movement of the laying arm 27 about the support-side pivot axisS. Provision is madefor a pivot stop (not illustrated), which limits a downwards pivoting of the laying arm 27 in thevertical plane towards the winding drum 5. Thepivot stop ensures that the engaging wheel 43 does not push between two winding loops, which have already been placed, and pushes completely through them, so as to avoid a contact engagement of the engaging wheel 43 with a complete winding layer located therebeiow. The pivotable movability of the laying arm 27 and the position of the pivot stop are secured thereon relative to the laying arm 27 in such awaythat the engaging wheel 43 is in roiling contact with the cylindrical drum core 7 or with the winding layer, which was placed most recently, in response to the back and forth laying movement. The pivot stop, however stops a lowering of the engaging roller 43 maximally starting at half of the thickness of the plastic tube 3, so that a roiling contact on the winding layer, which was laid completely most recently, is prevented.

The support 23 can be laid relative to the stationary axis of rotation 13 or to the stationary reference bottom B of a production hali, in that the adjusting robot 71, which is installed on the reference bottom B in a stationary manner, grips the support 23, holds It and positions it accord! ng to the wi ndi ng process accord! ng to the control.

The movement axes of the adjusting robot 71 are illustrated in part in Figure 5, wherein the adjusting robot 71 can linearly move the support 23 in the horizontal direction, which corresponds to the axial direction (axisof rotation 13) and substantially to the laying direction V, and in lifting direction A, and wherein the adjusting robot 71 can pivot the support 23 about the lateral contact K (about the axis of rotation D).

The engaging location of the engaging wheel 43 with the drum core 7 or thewinding layer, which has already been placed, forms an actuating location, at which the laying arm 27 is axially displaced by means of the axial growth of thewinding layer 15 so as to lead with respect to the support 23. This can be identified as a flexibly reacting consecutive movement of the laying arm 27, which immediately follows the continuous axial laying of the winding loops 17 and the axiai growth of thewinding layer 15. A vertical pivoting movement about the pivot axis S because the engaging wheel 43 bears on thewinding drum 5 and because of a radial growth of thewinding layers, realizes a consecutive adjusting of the laying arm 27, which is mounted on the support 23, which is stationary for the time being. The yielding movement of the laying arm 27 and the readjusting movement of the support 23 are suggested by means of the double arrows V, A in Figures.

The adjusting robot 71 holds the support 23 by means of the rail 51, which cooperates with the carriage 53, which is formed from a base plate 55 and a profile support 57, which extends downwards therefrom. The carriage 53 and the rail 51 form a translatory mounting, the translatory laying direction V of which is determined substantially or approximately parallel to the horizontal axial direction (axis of rotation 13). The carriage (53)-raif (51) arrangement provides a freedom of movement to the laying arm 27 with respect to the support 23 only in the laying direction V, so that the carriage 53 can be displaced reiativeto the adjusting robot 71, in particular thegripper arm thereof (not illustrated) only in the laying direction V.

The rail (51)-carriage (53) arrangement provides an axiai resilience for the laying arm 27. The axial resilience is created by means of the level of freedom of movement in the laying direction V. So that the engaging wheel 43 does not lose the contact to the lateral side of thewinding loop 17, which was placed most recently, in response to the laying process between the two side flanges 11a, 11b, a restoring or pretensioning device 61 acts between the carriage 53 and the rail 51, which generates an elastic restoring or pretensioning force, as soon as the laying arm 27 is deflected from a predefined neutral position relative to the support 23, in which no restoring forces of the restoring device 61 act between the rail 51 and the carriage 53 in the laying direction V, driven by the axial expansion of the winding layer 15. The larger the deflection width of the laying arm 27 from the neutral position, the higher the amount of the restoring force. The restoring device 61 is formal by a pair of pneumatic actuators 63, 65, the details of which are suggested in Figures 7 to 10. To generate the restoring force, a pneumatic actuator 65 or 63 is only active in one of the laying directions V (for example from the side flange 11a to the side flange 11b), while the other pneumatic actuator (65 or 63) is active in the opposite laying direction V (from the side flange 11b to the side flange 11a). if the laying arm 27 is moved in the laying direction V by means of the periodic, horizontal laying of the winding loop 17, the end 33 of the laying arm 27, together with carriage 53, displaces in the linear laying direction V relative to the rail 51, which meanwhile remains stationary in the position thereof without being influenced, until if is readjusted by the adjusting robot 71, for example in response to exceeding a deflection threshold of the carriage 53, which reduces the restoring force of the restoring device. Due to the relative movement between the carriage 53 and the rail 51, the pneumatic actuator 63 or 65 (depending on the axial laying direction) acts in a pneumatically tensioned manner, so that the pneumatically elastic restoring force is generated in the pneumatic actuator 63, 65, which is communicated to thelaying arm 27 via the carriage 53 and which finally axially pretensions the engaging wheel 43 against the free lateral side 18 of thewinding loop 17, which was wound most recently. It isensured by meansof the axial restoring pretension that all winding loops 17 are placed close together adjacent to one another in the axial direction, so as to reach the desired even winding sequence and so that geometric as well as material-specific anomalies can be responded to so as to adapt thereto in a flexible manner. it shall be dear that the pneumatic actuator 63, 65 can also generate an actively controlled, pneumatic restoring force, independent from the laying of the laying arm 27, in that the pneumatic actuator is for example activated pneumatically via a open-loop-control and/or closed-ioop-controi device, which is not illustrated in detail, for example as a function of a predetermined operating state. To realize a setup, which is as simple as possible, the pneumatic actuator 63 is uncontrolled and builds up (only) elastic restoring forces, when thelayingarm 27 is moved out of its neutral position info the laying direction V,

To keep the axial restoring force, which pushes the engaging wheel 43 against the free lateral side 18 of the last winding loop 17, substantially constant, the axial deflection between the carriage 53 and the rail 51 is kept substantially constant or at least within a threshold range. A non-illustrated distance sensor is used for this purpose, which monitors a predefined minimum and maximum setpoint deflection amplitude with the help of a open-loop-control and/or closed-loop-control device (not illustrated in more detail), if said setpoint deflection amplitude is exceeded or fallen below, respectively, the adjusting robot 71 guides the rails 51 following the deflection movement of the laying arm 27, wherein the foliowing step can correspond approximately to a thickness of the plastic tube 3. It is ensured in this way that the elastic restoring force is reduced by meansof retracing the rail 51 by theperiod setup of the deflection.

To realize the desired winding around the drum core 7 of thewinding drum 5, the plastic tube 3 is subjected to a constant tensile pre-loading force as far as possible in the longitudinal direction thereof in response to being wound around the drum core?.

According to the invention, an electromagnetic brake, in particular an eddy current brake 67, which can be brought from an active operating position, as it can be seen in Figure 10, into a passive operating position (see Figure 9), is arranged on the support 23, in particular on the carriage 53. The eddy current brake 67, which can be positional and manipulated, if necessary, by a open-loop-control and/or closed-loop-control device, which is not iliustrafed in more detail, serves the purpose of reporting the substantially even tensile pre-loading force to the plastic tube 3. As an example, the eddy current brake 67 can have two magnetic rotors, which rotate in an electromagneticaily generator magnetic field, wherein the respective magnetic rotor can be retracted and extended to adjust the electromagnetic brake force. To introduce sufficient friction delay forces into the plastic tube 3, provision is made for a toothed belt 72, which is clamped around two deflection rollers of the eddy current brake 67. The toothed belt 72 has teeth, which run transversely, to ensure a desired engagement with the plastic tube 3 and the frictional force transfer. In the case of an alternative embodiment of the belt 72, provision can also be madefor a mountain-valley profile, which runs in the longitudinal direction and which is formed so as to be form-complementary to the plastic tube 3.

It wifi be described below, how anew winding layer 15, which is“elevated” in the radial direction of thewindingdrum 5, is initiated, when approximately one winding layer was concluded on the drum core 7 or on a winding layer, which has already been placed, and when a “new” layer forms thereon. For thispurpose, referenceisin particular made to Figures 2a to 4b.

An operating state can be seen in Figures 2a and 2b, in which a first winding layer 15 is almost completof on the drum core 7. The engaging wheel 43 runs on the cylindrical drum core 7, wherein the axial restoring force, which is generated by the restoring device 61, axially pushes thewinding loop 17, which had just been placed, against the adjacent winding loop. Beforethe last winding loop 17 of the first winding layer 15 is now concluded, the contact wheel of the contactor maker 37 comes into a roiling engagement with theinner side41 of thesidefiange 11a. As the winding process continues, the contact wheel is deflected horizontally, whereby the control signal of the contactor maker 37 is sent to a open-loop-controi and/or closed-ioop-control device, which is not illustrated in more detail. After receiving the control signal, said open-ioop-control and/or ciosed-loop-control device prompts a vertical lifting of the laying arm 27, in that the adjusting robot 71 lifts the support 23 and the rail 51 thereof in the lifting direction A substantially by not more than the thickness of the plastic tube 3, wherein the vertical pivot stop, which is not illustrated in more detail, entrains the laying arm 27 in the vertical lifting direction, to lift the winding drum-side end 33 of the laying arm 27 by slightly more than the outer diameter thickness of the plastic tube 3 above the winding layer 15 which was just ended. This operating state of the lifted winding drum-side end 33 can be seen in Figures 3a and 3b, as well as the deflected contactor maker 37. In the axial end position of the winding drum-side end 33 of the laying arm 27, there is temporarily no contact between the engaging wheel 43 and the plastic tube 3. By means of continuous further winding, the plastic tube 3 is placed into the winding gap to the side flange 11a, which remains, until the first winding loop of the "new” winding layer 15 forms. The freely accessible side area of the engaging wheel 43 first comes into a lateral contact K with the lateral side 18 of the first winding loop 17 of thewinding layer 15, is to be newly laid, wherein the roiling surface of the engaging wheel 43 is temporarily lifted while still at a distance from the winding layer 15, which has already been placed completely. The engaging wheel 43 lowers only after the first winding loop 17 entrains the engaging wheel 43 in the laying direction V, so that the rolling surface thereof comes into rolling contact with the completely placed winding layer 15. This operating state can be seen in Figures 4a and 4b, in which the engaging wheel 43 is in rolling contact with thewinding layer 15, which was just placed on the one hand, and, on the other hand is in lateral contact K with the lateral side 18 of the first winding loop 17 in a pretensioning manner with the uncovered side area thereof. In this operating state, the laying arm 27 is already moved in the axial direction relative to the support 23 again, whereby the restoring device 61 generates the restoring force, which pushes the engaging wheel 43 against the winding loop 17, which has just been placed. The fact that the laying arm 27 is already deflected away from the axial end position, can also be seen from the position of the contact wheel of the contactor maker 37, which is located in the passive operating state again and which is no longer in rolling contact with the inner side 41 of thesidefiange 11a.

It can be seen in Figure 6 that, in its axial end position, which is illustrated in Figure 6, the laying arm 27 is inclined at an angle of attack a to the horizontal radial direction Hr, according to which the laying arm 27, based on the winding drum-side end 33, is inclined away from the right side flange 11a to the winding drum center. This ensures that the contact wheel of the contactor maker 37 has sufficient space for a pivoting in order to generate and to output the control signal, without the end 33 of the laying arm 27 coming into contact conflict with the inner side41 of theside flange 11a, 11b.

In the course of the axial laying movement from the right side flange 11a to the left side flange 11b, a (positive) angle of attack a decreases, so that the longitudinal extension of the laying arm 27 coincides with the horizontal radial direction Hr approximately in the axial center of the winding drum 5, while the laying arm 27 in the opposite axial laying end position is also inclined to the center of the winding drum 5 in a (negative) angle of attack a, in particular of the same size, in this position, thecontactor maker 37 can also trigger securely in that the contact wheel is pivoted laterally.

In the case of both axial laying end positions of the laying arm 27, the side flange 11a, 11b, which extends in the radial direction, does not come into movement conflict with the laying arm 27, which is inclined thereto.

The already mentioned open-loop-control and/or ciosed-ioop-control device, which is not illustrated in more detail, which can in particular be accommodated on the supporting structure 30, can in particular be used exclusively to adjust the angular speed of thewinding drum 5 as a function of the radial and/or axial position of the guide (of the laying arm 27), in particular of the winding drum-side end 33 thereof. It shall be clear that the open-loop-controi and/or closed-loop-control device can also takeover the above-mentioned control functions. The open-loop-controi and/or closed-loop-control device is preferably fixedly connect ai to the base plate 55. However, other fastening locationscan also be considered for the open-loop-control and/or closed-loop-control device. I n response to the helical laying of the plastic tube 3 onto the winding drum 5, the leading end of the plastic tube is first threaded through an opening in the side flange 11 of thewinding drum 5 and is manually wound by an operator, immediately adjoining the inner side 41 of the side flange 11a, 11b, for the first winding layer at a slow angular speed (see Figure 11; START), wherein the angular speed U increases gradually.

Before the winding begins, the position determination of the laying arm 27 is initiated in the open-loop-controi and/or closed-loop-controi device, namely set to "0”. Starting with this initiation of the laying process (at START according to Figure 11), an in particular continuous detection of the position of the laying arm 27 begins. After first windings of thewinding layer 15 (for example see Figure 1) bear on the drum core 7, the winding speed U is increased to a maximum winding speed Umax, so that the maximum winding speed Umax: is reached starting at a variable or previously fixedly set adjusting position Xi for the first winding layer 15. During the helical laying of thewinding layer 15 in the so-called axial center area C of the winding drum 5 (see Figure 6), which is between X, and X2, X5 and X6 (Fig. 11) or between the axial adjusting positions Pa and Pb (Fig. 6), the maximum winding speed Umax is to be kept constant (see Figure 11).

It shall be clear that thecorrect winding speed of thewinding drum 5 isessentiai for thewinding success, it goes without saying that the regulating processcan also be adapted to the respective winding layer 15 by means of the circumferential speed. To simplify matters, reference is made in the figure description to thewinding speed as regulation variable.

When the laying arm 27, coming from the adjusting center area G, reaches the predetermined axial adjusting position X2 or Pa or Pb, respectively, which can be determined for example by detecting the axial position of the laying arm 27 or by detecting the already wound winding material length, the open-loop-control and/or closed-ioop-control device triggers a so-called side flange or turning operation, in response to which the winding speed is first continuously reduced gradually, namely to a minimum angular speed Umin, which is to be kept constant during the further sensitive wail operation (X3-X4) (Fig. 11), Once the wail operation is concluded (at X4), in particular in response to reaching an adjusting position after the laying arm 27 begins to move to the opposite (laying arm-remote) side flange 11a or 11b of thewinding drum 5, the winding speed increased steadily in a continuous manner between X4 and X5 according to the prior wind!ng speed decrease between X2 and X3, and reaches the angular speed Umax in the adjusting position X5, which can be predetermined or which can be calculated during thewinding process.

It shall be clear that Figure 11 does not illustrate the direction of the axial movement of the laying arm 27, but only the angular speed U as a function of an absolute, axial adjustment travel amount |XI from the START. The axial direction of movement of the laying arm 27 changes in the case of the respective actuating positions X', X”, of the sequence of which the minimum angular speed Umin remainsconstant.

In general, the actuating positions can either be input by input info the open-loop-controi and/or ciosed-loop-control device in a predetermined manner or can be calculated during the wind!ng process and can be changed depending on the winding progress.

Figure 12 illustrates the turning operation by means of a distance-time diagram, in which the axial displacement X with respect to the time t is illustrated. In that moment when the turning position is reached by the guide, the laying arm 27, the time to is relevant. Prior to reaching the turning timeto, a tiered graph form can be seen accordingto Fig. 12, in which thegradual move-up of the laying arm 27 in theaxial direction with respect to the leading winding layer during the normal winding process is to be clarified. It shall be dear that a stepped shape is not necessary, but that other, in particular curved trajectories are possible as well. It is important to note that axial restoring forces, which push the laying arm 27 against the free lateral side 18 of the last winding loop, are built up, in that the laying arm 27 is displaced forward relative to the support 23 of the guide in the axial direction X by means of the winding progress; the helical winding, which builds up axially, pushes the laying arm 27 against the elastic pretensioning device, which acts inside the guide, whereby elastic restoring forces are built up due to the relative movement.

When reaching the turning position Xo at the time to, the turning operation is triggered. When the turning position Xo is reached, the open-loop-control and/or closed-loop-coniroi device initiates a vertical free travel of the laying arm 27 away from the winding drum 5, wherein, according to experience, a radial free travel of 30 m is sufficient to compensate maximum radial imbalances of the drum core7of thewindingdrum 5. It isessential in response to the free travel of the laying arm 27 to always position the drum-side end 33 to thewinding layer 15, which was placed most recently, in a contact-free manner. During the radial free travel time t0 to ti, according to which approximately Q.8 rotations of the winding drum 5 are covered, the laying arms 27 is not displaced in theaxial direction and remains on the turning position Xo. The axial distance (X) does not change until the time ti.

Figure 11 and Figure 12 are related Insofar as the turning position Xo according to Figure 12 substantially corresponds to the position X2 or X6 according to Figure 11. During the time to to ti, during which the laying arm 27 remains at the turning position Xo (X2 or X6, respectively), the angular speed U still remains unchanged.

Starting at the end of the free travel ti, the support 23 and thus the laying arm 27 (the end 33 of which no longer bears on the placed winding layer), is moved forward further in the axial direction all the way to the side wail flange 11a, 11b of the winding drum 5, to ensure that the winding drum-side end 33 of the laying arm 27 always bears completely on the sidewall flange 11a, 11b during the entire rotation of the winding drum 5. Theaxial forward displacement travel is illustrated with Xo to Xi in Figure 12. After concluding the forward displacement at the time t2, thewinding drum 5 can be rotated further by approximately 0.4 rotations.

At the time ti (at the turning position Xo (X2 or X6, respectively, according to Figure 11), the speed for the further displacement forward of the guide is reduced.

Starting at the end of the forward displacement (t2, Xi), a position correction of the laying arm 27 or of the support 23, respectively, can be performed to adjust for example the restoring forces in the rail-carriage mounting or to change the position of the laying arm 27 relative to the winding drum 5. The correction phase can last for approximately 0.6 rotations of thewinding drum 5.

Towards the end of the correction Ϊ3, the guide, namely the support 23, together with the laying arm 27, is positioned in the forward laying direction of movement, which is opposite to the backward laying direction of movement, to place the laying arm 27 without contact with respect to the side wall flange 11a, 11b of the winding drum 5. The move-back path is thereby approximately identical to the displacement forward path, but it can also be realized to be larger or smaller, so that it is ensured that the winding drum-side end 33 of the laying arm 27 no longer reaches into the contact area of the side wall flange 11a, 11b of the winding drum 5. The move-back can last approximately 0.2 rotations of thewinding drum 5. At the end of the move-back t4, the laying arm 27 is lowered back to the winding layer 15, which has already been laid, and thus comes into rolling contact. During the lowering of the laying arm 27 to the time t5, the support 23 of the laying arm 27 remains in the axial position, which corresponds in particular to aneutral position, in which no restoring forces act. At thetimet5, the newly placed winding ioop comes into direct lateral contact with the engaging wheel 43 and entrains the laying arm 27 in backward laying direction of movement, which is to be represented by the graph form, which is inclined downwards. So as not to allow the restoring forces to become too large, as described above, the support 23 is guided by the adjusting robot 71 relative to the laying arm 27, which abuts. At the time t5 at the earliest, the change of the angular speed to Umax is to be begun, so as to attain a winding alongthedrum core 7, which isasquick as possible.

In general, the axial displacement X refers to the adjusting movement of the support 23, wherein the displacement of the support 23 by the adjusting robot 71 and the flexible adjustment of the laying arm 27 is approximately identical in the case, when the laying arm 27 is not supported on the sidewall flange 11a, 11b of thewindingdrum 5 or the lateral side of the last winding loop due to the slide bear! ng on the support 23 and thewinding advance.

To facilitate the readability of the figure description, details of a preferred embodiment of the laying arm 27 according to the invention are illustrated in Figures 13 to 18, wherein identical reference numerals were used for similar or identical components of the laying arm 27, which has been described above by meansof the previous figures.

The laying arm 27 comprises three main components, namely the arm base 28, on which the winding material is inserted, the winding drum-side end 33, on which the winding material is delivered, as well as an elongated supporting structure 30 located therebetween, which forms the majority of the laying arm 27. Thewinding drum-side end 33 is releasably and exchangeabiy connected to the supporting structure 3Q via interfaces 110,111. it is sufficient in this way to only exchange thewinding drum-side end 33 with a dimension-adapted one in response to changing the dimension of thewinding material, while ail other components (28, 30) of the laying arm 27 can be kept. These other components are embodied independently of the dimension of the winding material. Only the winding drum-side end 33 is embodied in a winding material-specific manner due to the contactor maker 37, which will be described below as alternative embodiment, and thewinding material delivery 34.

As can be seen from Figures 13 to 18, the contactor maker 37 is embodied in an alternative embodiment without contact wheel, but is realized with actuation projections 101a, 101b, which run on the side flange wail 11a, 11b so as to drag along it. The actuation projections 101a, 101b are part of a closed bracket or ring structure of the contactor maker 37, which, in top view, has a triangular shape comprising two long legs of the same side, which are each located at an angle of approximately 15° to the longitudinal extension of the laying arm 27. The long legs extend to a connecting front side short leg, which forms the free end of the contactor maker 37 and of the winding drum-side end 33. Cornersof thetriangular ring structure are rounded.

The actuating projections 101a, 101b, together with the ring structure, are pivotably mounted about a pivot axis 100, which extends in the vertical direction, so that the respective actuation projections 101a, 101b are in each case retract at with the respective side wall flange 11a, 11b in a pivoting manner in such a way that the corner area thereof is located at the height of the outer surface of the contact area 38a, 38b and that no distance projects laterally beyond the outer surface. In this release position of the respective actuating projection, the placing contact area 38 of thewinding drum-side end 33 of the laying arm 27 touchesthe inner side of the respective side flange wall 11a, 11b. if thelayingarm 27 is moved away from the respective side flange wall 11a, 11b and if the placing contact area 38 is released, the ring structure of the contactor maker 37 reaches independently into the middle, unactuated position thereof (see Figs. 13-18) by means of a coercive, which is not illustrated in more detail, such a s a spring, preferably a torsion spring. The spring pretension can engage directly with the ring structure or with a gear part, such as the pivot axis 100, etc.

The contactor maker 37 is equipped with an angular gear 103 to transfer the pivoting movement of the vertical pivot axis 100, which is rigidly coupled to the ring structure, into a pivoting movement about atransfer shaft 105, which extends in the longitudinal direction of extension of thelayingarm 27. The translation of the angular gear 103 to transfer the pivoting movement is preferably 1:1. A signaler (not illustrated), which isarranged on the supporting structure 30 and which outputs an electrical control signal after the onset of the movement or after exceeding a predetermined pivot amplitude of the ring structure to inform the open-ioop-control and/or closed-ioop-control device that the turning operation is to be initiated, is coupled to the transfer shaft 105. The control signal can be triggered directly at the onset of the pivoting or only with a delay after reaching a predetermined pivot amplitude.

The transfer shaft 105 is divided into two parts, wherein the distance sensor-side shaft section 107 is coupled to the supporting structure (30)-side shaft section 109 by means of a releasable claw coupling 110, which allows for a removal of the front and rear shaft section 107, 109 from one another. The signaler connects to the shaft section 109. In addition to the claw coupling 110, the guide and holding plates 31b and 31a aiso form a separable interface 111 to separate a housing plate section, which faces the wind! ng drum 5, from a base-side housing pi ate sect! on.

The assembly interfaces (110, 111) make it possible to uncouple the winding drum-side end 33, together with thefunctional elements thereof, such asthe winding material delivery 34, delivery wheels 35, contactor maker parts as well as the mechanical communication of the contactor maker 37 to the signaler, so as to be able to adapt the device according to the invention and in particular the majority of the laying arm 27 according to the invention, depending on use for a winding material of a certain dimension, it has been shown that those components in the transport space 32 on this side of the assembly interfaces (110, 111) can be designed for a plurality of winding materials of different sizes, but that thewinding drum-side end 33 needsto be adapted in a winding material-specific manner with respect to the dimensioning. The winding material delivery 34 and the actuation projections 101a, 101b, which project from the contact area38, need to in particular be adapted to thewinding material thickness.

The purely mechanical realization of the contactor maker 37 all the way to the signaler on the basisof releasable couplings, such as the claw coupling 110, is particularly advantageous, so that no electronic signal transfer Is necessary between thewinding drum-side end 33 and the open-loop-controi and/or closed-loop-control device, which is arranged on the support side. An exchange of thewinding drum-side end 33 can be accomplished purely mechanically in this way, whereby inexperienced operating personnel can aiso perform achange of thewinding drum-side end 33 to adjust the laying arm 27to thewinding material, which isfo be wound.

The features disclosed in the above description, the figures and the claims can be significant for the realization of the invention in the different embodiments, both alone and in any combination.
