Description

Apparatus and method for winding a rope-shaped winding material

The invention relates to a device and a method for the winding winding of a strand-like winding material, such as a continuously extruded tube, preferably made of plastic on a rotating winding drum. In the winding material, such as an extruded plastic pipe, such as a cable duct, in which a fiber optic cable can be installed protected, it is inter alia important to keep the winding material in a length of several hundred meters in a limited building site in stock, in particular underground to move long distances.

It is known to wind the winding material on a winding drum or reel and to transport the wound drum to the construction site. On-site, it can be handled as needed.

For reasons of production economy, the winding-up operation directly adjoins the production process, in particular the extrusion, of the winding material, so that the extruded plastics material leaves without leaving a cooling station and is fed to the winding device. The winding process itself is then usually controlled by an operator and optionally manipulated manually.

When using a cable protection tube as a winding material usually a standard winding drum made of wood is used. The cable protection tube wrapped on the wooden winding drum is delivered to construction sites to install it as required. Such cheap, standardized wooden winding drums or other winding drums have proven themselves due to a relatively low price and the possible reusability especially in use on construction sites. However, the winding drums have rotationally asymmetric axial and radial impacts due to imbalances on the lateral side flanges and on the drum core. Because of the geometric irregularity of the winding drum is a constantly supervised by an operator according to the prior art and manipulated winding of the winding material necessary. In addition to unpredictable differences in geometry of low-price drums, automation has not yet been achieved insofar as the material properties stabilize only after a long curing time in plastic pipes, so that the winding property of the plastic pipe after and during winding can hardly be predicted due to changes in the material properties after extrusion , Such individual hardly predictable winding conditions require an operator with many years of winding experience when monitoring and manipulating the winding material. So far, an at least approximately completely automated winding without manual assistance of an operator, especially at a winding speed of over 100 m per minute could not be achieved.

Winding methods and winding devices are known per se in automation technology, in which electric cables are wound onto geometry-precise rollers. EP 0203046 B1 discloses, for example, a cable winder in which a guide arm, which is directed to the winding roll, has a plurality of arm members, which are connected to one another by means of a plurality of wrist joints. However, it has been found that ideal conditions exist for the cable as well as for the rotationally symmetrical winding drum in the known winding automation processes, which relates to the geometry of the winding drum as well as the material properties of the winding material. Straight wire winders are products of high material quality and uniform and constant material properties. For such windings, a higher cost is operated to provide ideal geometric, unbalance winding coils. It has been found that the known automated winding techniques can not be used successfully when a winding material and a winding drum are used whose material or geometry properties are unpredictable.

It is an object of the invention to overcome the disadvantages of the prior art, in particular to provide a method and an apparatus for winding a strand-like winding material, such as a continuously extruded tube, preferably made of plastic on a winding drum, wherein a higher degree of automation can be achieved in which a manual intervention by an operator is as far as possible unnecessary.

This object is solved by the features of claim 1. Thereafter, a method according to the invention, according to the invention winding (oscillating) of a strand-like winding material, such as a continuously extruded tube, preferably made of plastic, on a rotationally driven winding drum, such as a spool core provided. The winding drum is to be mounted rotatably, wherein the axis of rotation preferably remains stationary, so that the axle fixed winding drum executes exclusively a rotation about the rotation or winding axis. In the winding method according to the invention, the winding material of the rotating winding drum is transferred via a guide mounted for an axial back and forth laying movement. Preferably, the guide comprises a laying arm, through which or through which the winding material is guided until it is delivered to the winding drum. Preferably, the laying arm is supported on a carrier, such as a rail structure, in the manner of a carriage. It may be formed a rail carriage storage between the laying arm and the carrier. The guide is made relative to the winding drum essentially the winding progress and the laying arm in particular lagging, preferably the carrier is adjusted by means of a handle or actuating device, such as a robot, substantially following the winding progress. According to the winding method according to the invention, a turning operation is performed upon reaching a particular pre-determined, in particular a locally predetermined, depending on the size of the winding drum, or a sensed turning position.

The turning position can be determined in advance by operator input of a specific location coordinate substantially relative to the winding drum in a particular electronic control and / or regulating device. It can also be calculated and possibly corrected by an appropriate control routine using position sensors depending on the winding operation during the winding process. It has been found that the turning operation, irrespective of which radial winding position, reliably achieves, taking into account a certain defined, in particular the same sequence of method steps, even at higher winding speeds in order to achieve a compact and error-free winding result.

At the beginning of the turning operation, the incoming in a Hin-laying movement to the turning position guide away especially in a substantially radial vertical direction away from the winding drum, in particular raised in the vertical direction, in particular a preferably rolling on the winding drum contact end of the guide on the Winding drum or the last wound helical layer is present, in particular unwinds to completely and permanently free from the contact engagement.

According to a first aspect of the invention, the turning operation is specified in that during or after the removal of the guide, in particular the carrier to a particular predetermined axial Nachrückstrecke (starting from the turning position) is further advanced in the axial Hin- laying movement relative to the winding drum, in particular to allow an axial driving over the predetermined or sensed turning position. In this way, it is ensured that the guide on the inside of a radially extending side wall flange of the winding drum is always in lateral contact with the side wall flange during the rotation of the winding drum. The advancing is intended to ensure that even a temporary contact loss between the guide and the sidewall flange of the winding drum is avoided. Should the guide already be in contact with the sidewall flange of the winding drum when the turning position is reached, advancing will either (only) displace the support of the guide movably supporting the laying arm, resulting in an increase of a biasing force acting between the laying arm and the carrier Can lead biasing device, and / or possibly a change in the inclination angle of a longitudinal extension of the laying arm relative to the radial direction of the winding drum. In this case, the laying arm is substantially pivotally mounted on the support in a reciprocating laying plane to allow different angles of inclination of the longitudinal extent of the laying arm relative to the winding drum, in particular to the side flange of the winding drum. According to the invention, with the advancement of the guide after reaching the turning position, secure contact of the guide with the side wall flange of the winding drum is achieved, which ensures a safe reference point and stable axial support of the laying arm during the turning operation.

In addition, after advancement, a position sensor can detect the position of the laying arm, in particular its free contact end, in space in order to define a local initialization, ie a zero position, of the laying arm for starting the construction of the next spiral layer.

With the measure according to the invention, a reliable automation of the winding material, in particular of a nonhomogeneously behaving plastic pipe, can be applied to a non-ideal symmetrical winding drum, even at high winding speeds of up to 100 m (meters) per minute and beyond can be achieved.

In a preferred embodiment of the invention, the turning position is reached when the extending to the winding drum laying arm of the guide is in abutting contact with a Seitenwandflansch the winding drum or at a Wickeltrommelseiti- gene end of the laying arm arranged contactor triggers a contact signal. The contactor can be arranged on a winding drum-side end of the laying arm of the guide. The winding drum-side end should be in abutting contact with the side flange of the winding drum during the turning operation, for which reason the winding drum-side end has a contact area facing the sidewall flange, at which the laying arm should come into abutment with the side wall flange. The contact can be designed as a plant contact or as a rolling contact. When the turning position of the guide is reached, the contactor should preferably generate and output a control signal, namely the turn-on operation triggering signal. The control signal is to be sent to an electronic control and / or regulating device, so that the control routine can trigger a control for changing a certain control variable of the winding process. For the turning operation, the control and / or regulating device can complete the already almost finished winding layer and start the new winding layer on the closed winding layer. In the turning operation, a change of direction of the laying movement is associated with the guidance. The contactor has in the region of the contact area in each case an actuating projection which protrudes in an unactuated position of the respective contact area in back and forth installation direction and is preferably movable, in particular pivotally mounted on the laying arm of the guide, so that the respective actuating projection in a Release position the respective investment area for the contact with the side wall flange releases. The contactor, with its actuating projection protruding in the direction of movement of the back and forth movement, allows the control signal to be triggered before the laying position of the laying arm is reached, which is only reached when the movement of the guide in the guide according to the first aspect of the invention is achieved Hin-laying movement direction has been completed.

In a further development of the invention, the latter is sunk in vertical direction in the laying arm of the guide in the release position of the respective actuating projection. The laying arm may in particular be limited by plates, which preferably comprise a completely closed transport space in which a pivot axis of the actuating projection can disappear. The actuation outer side of the respective actuation projection is contour-adapted on an outer surface contour of the contact region, so that in the release position the actuation outer side essentially lies in the plane of the outer surface of the particularly planar contact region.

In a preferred embodiment of the invention, the actuating projection is in its unactuated position at least by half or all Wickelgutstärke and at most by two Wickelgutstärken from the respective contact surface in forward or Her- laying movement direction.

In a further development of the invention, the guide remains during the radial removal substantially without axial feed substantially in the turning position, at least as far as the axial direction of laying movement.

Preferably, the advancing is only caused when the removal of the guide away from the winding drum is at least largely completed and / or if after reaching the turning position, a predetermined winding path or time has expired. The winding path or time can preferably be determined in advance, for example, by running at least one half revolution of the winding drum and highest of at least one and a half revolutions of the winding drum.

In a particular embodiment of the invention, the lifting should be completed after the trigger signal after about 0.8 revolutions of the winding drum. After reaching the turning position, the advance should be triggered only when about 0.8 revolutions have expired since reaching the turning position.

In a further development of the invention, after advancing by means of an actual position measurement of the guide, the axial position of the guide relative to the turning position, in particular to the sidewall flange of the winding drum, is controlled in the axial backward and forward movement direction and optionally corrected. The correction can serve to compensate for axial shocks of the sidewall flange without loss of contact. In addition, the correction can also serve to reduce the zero position of the leadership, in particular fend to monitor the slide rail mounting of the laying arm on a robot-side support and adjust if necessary.

For example, the position correction can be triggered only after a certain winding distance or time, which is preferably determined in advance by expiration of at most a three quarters or half turn of the winding drum. In particular, therefore, the advance should be completed within a 0.4-fold revolution of the winding drum. Thereafter, if necessary, a correction of the axial position can be triggered.

In an alternative or combinable aspect of the invention, the advancement of the guide beyond the turning position can be omitted and, if necessary, only a position correction can be carried out after reaching the reversing position. According to the invention, the guide is instead of or after the axial advancing and possibly the position correction in the axial, the Hin- moving direction opposite Her-laying movement relative to the winding drum back particularly away from the Seitenwandflansch away, in particular to put the guide back to the turning position and / or in particular to spend safe from the contact with the side wall flange and to provide the guide contactless to the side wall flange of the winding drum.

At the turning position should preferably be ensured that during complete rotation of the side wall flange contact between the guide and the side wall flange is always excluded even in the range of Axialschläge. The retraction is to be triggered when a predetermined winding distance has elapsed, in particular by the expiration of at most one or a half turn of the winding drum since the completion of removal, advancement or correction if necessary, or by expiration of at least one or one and a half revolutions is preferably set in advance since reaching the turning position.

In a preferred embodiment of the invention, after advancing and / or returning, the guide is moved in a vertical direction towards the winding drum, in particular lowered, in particular a free contact end of the guide with the winding drum or an already wound winding layer in contact , preferably in drain or rolling or sliding contact to bring. During the radial approach, the guide can substantially without axial feed, in particular on the Turning position remain. A laying movement leaving the turning position is only initiated when the approach of the guide is at least for the most part completed and / or when the contact end of the guide is brought into contact with the already wound winding layer.

A laying movement leaving the turning position is only initiated when the approach of the guide is at least for the most part completed and / or when the contact end of the guide is in contact with the already wound spiral layer. Preferably, the movement of the guide directed to the winding drum is initiated after a predetermined winding distance or time, preferably by at least half a revolution of the winding drum since the completion of advancing or retreating, or by elapse of at least one and one-half turns of the winding drum since the reversal position has been reached is determined in advance.

In a further development of the invention for the winding after completion of the turning operation the leadership in the back and forth laying movement towards the turning position according to a prescribed winding routine relative to the winding drum, according to the wkelkel drum side contact end of the laying arm of the guide with the winding drum or the last laid winding layer is preferably rolling in a contact engagement and / or according to which the guide is advanced along a reciprocating laying path between the respective sidewall flange adjacent turning positions according to the axial winding growth on the winding drum. In this case, the laying arm of the guide, which is mounted relative to a handle or adjusting device, such as a robot, in particular linearly in the axial direction, for example by means of a slide rail storage, in particular according to a predetermined or regulated Nachrückweg the advancing be nacheilend nacheilend. When advancing and when moving forward, the laying arm can remain deflected relative to a neutral position, so that the laying arm is pressed axially laterally against the last winding loop placed on the winding drum. Preferably, a force acting on the winding loop actuating force acting against a free lateral side of the last-placed winding loop depends on the degree of deflection of the laying arm from the neutral position, in which in particular no restoring force acts.

Preferably, for the turning operation when removing the laying arm and when contacting, the laying arm is in a neutral position relative to the carrier, in which see the laying arm and the carrier act no biasing forces and only at a relative displacement of the laying arm relative to the carrier from the neutral position biasing forces are built up, which push back the laying arm and the carrier in their neutral position to each other. The laying arm can remain in the neutral position while advancing until the contact end of the laying arm comes to rest on the side wall flange. In accordance with an advancement of the guide beyond the turning position, a restoring force in the axial direction is built up on the carriage-rail support, which presses the laying arm against the last-placed winding loop. The degree of displacement of the laying arm relative to the carrier from the neutral position preferably corresponds to the advance travel of the guide after reaching the turning position. For correcting and / or returning the laying arm, the laying arm can essentially be brought into the neutral position for the turning operation, so that essentially no restoring forces act. When moving the laying arm on the winding drum to the laying arm is in the neutral position, wherein, as soon as the contact end of the laying arm comes into engagement contact with the winding layer, then the laying arm is deflected according to the winding progress through the last laid winding loop from the neutral position to to generate the biasing force on the laying arm.

In a further development of the invention, in the axial course of the winding according to the invention, a winding base is set the winding speed of the winding drum as a function of the particular axial setting position of the guide relative to the winding drum.

According to an independent winding method which can be combined with the above-defined method according to the invention, the winding material of the rotating winding drum is transferred via a guide mounted for an axial back and forth movement. The winding drum is preferably mounted only for a rotational movement about an axis of rotation and is fixed in the axial direction. It is preferably the axial reciprocating movement mounted guide, which causes the helical shape of the winding material for a winding position on the winding drum. Preferably, the guide is realized by a laying arm, which is held by an actuating device, such as a robot, and is positioned parallel to the axis of rotation of the winding drum. The guide is placed or moved relative to the winding drum following the winding progress. According to the invention, the angular velocity of the winding drum is varied in the axial course of the winding according to the winding of a wound material layer, for example as a function of the particular axis of rotation of the winding drum. Alen and / or radial adjustment position of the guide relative to the winding drum, in particular to the drum core, adjusted according to a control routine, in particular regulated. For this purpose, a control and / or regulating device may be provided, which detects, for example by means of a coupled position sensor continuously or intermittently the control position of the guide relative to the winding drum and monitors the speed depending on the setting position according to the invention or in particular according to preset speed parameters. The angular velocity can additionally be made dependent on the radial position of the wound layer to be laid relative to the drum core, that is to say on the number of wound layers that are laid.

Preferably, when laying the first (initial) winding layer, so when creating the first winding directly on the drum core and starting from an axial contact with the side flange of the winding drum, the axial setting position of the guide to zero, "0" set. The width of the winding drum, the axial distance between the opposing and facing inner sides of the side flanges of the winding drum, is entered as a winding drum individual parameter in advance in the control device. When axially laying the winding, so when moving the guide in the axial direction, the position of the guide of a sensor, such as a non-contact sensor (light sensor) is picked up, or determined by indirect detection (using passed or wound winding lengths). When the guide approaches a side flange, for example, from a certain axial position near the side flange, the control routine triggers a reduction in the angular velocity to perform a so-called side flange or turning operation in which the hitherto incompletely wound reel is closed and an overlying one new winding layer should be started. For example, the turning operation may already begin before the last 4, 3 or 2 windings of the not yet completely wound winding layer have been laid. An increase or decrease in the angular velocity depending on the radial winding position can take place, for example, when 3 or 4 layers of the "new" winding layer are laid.

In the preferred embodiment of the invention, the angular velocity is changed when creating a winding material, which may also be a particularly wound last spiral position, in particular when reaching a preset Axialstellposition the guide relative to the winding drum. Additionally or alternatively, in the case of a loss of contact of a winding drum-side end of the guide with the winding drum or a last-mentioned contact loss detected in particular by a control and / or regulating device. wound angular position, the angular velocity can be reduced and can be increased again in particular at Wiederkontaktaufnahme the winding drum end with the winding drum or the last wound coil position, the angular velocity again. During winding and contact maintenance, in a preferred embodiment of the invention, the angular velocity can be kept constant.

In a preferred embodiment of the method according to the invention, the angular velocity of the winding drum is reduced in the course of the axial laying movement of the guide for approaching the guide to a side flange of the winding drum, preferably to a predetermined minimum angular velocity, which can preferably be kept constant. The approach movement of the guide can begin, for example, when only four, three, two or one winding must be created to complete the entire winding position. The time when the approach procedure begins may be determined, for example, by exceeding an already wound length threshold or by detecting a axial initiation point by a scanning sensor. In particular, the angular velocity for the creation of the first winding of the newly applied winding layer, ie the first, directly adjacent to the side flange winding of the uppermost winding layer, during the so-called side flange operation of the guide and when removing the guide from the side flange of the winding drum remain reduced, ie even with windings that follow the first winding. The reduced angular velocity may remain reduced after the turning operation for a plurality 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 velocity can be increased again to build up the winding layer along the axial direction of the winding drum and complete until the approach procedure is triggered again, as described above. Preferably, the angular velocity for the laying movement of the guide to the opposite, distant side flange, in particular in a predetermined axial or predetermined by the angular velocity control and / or regulation axial midfield, preferably up to the next approach point on the opposite side flange, such as an edge margin, increases so that the angular velocity can again reach a particular predetermined maximum angular velocity. The center region may preferably be predetermined in advance depending on the axial dimension of the winding drum used, for example in a range of 80 to 95% of the total axial extent between the opposite side flanges of the winding drum used. While the guide arm enters the control edge region and the guide arm reaches the particular predetermined axial control position, the angular velocity, preferably to the minimum angular velocity, is reduced for the next wall operation.

In a further development of the invention, the winding drum is operated with at least two angular velocities, preferably two angular velocities, both of which are driven alternately by the winding drum. Preferably, the first, in particular maximum, angular speed during the winding of the winding material along the axial actuating means region of the winding drum is adjusted to more than 50 revolutions per minute, preferably 70 revolutions per minute, in particular substantially constant. The second angular velocity, preferably the minimum angular velocity, is set to be substantially constant when a predetermined axial setting position of the guide relative to the winding drum is reached at less than 70 revolutions per minute, in particular below 50 revolutions per minute. Preferably, a transition between the first angular velocity and the second angular velocity is realized by means of a constant or continuous angular velocity change.

In a development of the invention, the axial actuating means region is delimited by two predetermined, winding drum-specific, axial setting positions, which, if exceeded, in particular initiate or terminate the abovementioned side flange operation. The limitation of the actuating means region, at which in particular the maximum angular velocity is operated, causes the first angular velocity to be preferably set to over 80 revolutions per minute during winding in accordance with the invention within the actuating means region. Experiments showed that angular velocities of 90 revolutions per minute or even more can be set. When winding the winding material layer between the respective predetermined axial setting position and the axial end of the drum, in particular the side flange of the winding drum, the second angular speed is preferably set at less than 70 revolutions per minute. It has been shown that an optimum speed for the side flange operation is about 65 revolutions per minute.

In a preferred embodiment of the invention, the actuating means region occupies more than 50%, preferably between 60% and 80% or 90% of the total axial total winding width between the two side flanges of the winding drum. The predetermined axial adjustment Position is set in particular at an axial distance to the end of the drum to less than 20% of the total axial winding width between the side flange of the drum. Additionally or alternatively, when leaving the Stellmittelbereichs at the respective predetermined axial adjustment position, the speed can be reduced, but also be increased, depending on how the material properties of the respective winding material to be wound are. Preferably, both predetermined axial adjustment positions are placed symmetrically to the radial center axis at an equal axial distance to the respective axial end of the drum.

In a preferred embodiment of the invention is for an approach of the guide to the axial end of the drum, in particular before the last or the penultimate winding loop of the winding material layer is placed, and / or after a position or displacement sensor, such as a contactor, at a predetermined setting position of the guide a trigger signal outputs, reduces the angular velocity of the winding drum. Alternatively or additionally, in the axial removal of the guide from the side flange, in particular after at least one or two multi-layer winding loops are completely laid, the speed can be increased to the maximum speed.

Furthermore, the invention relates to a device for winding winding a strand-shaped winding material, such as a continuously extruded tube, preferably made of plastic on a rotationally driven winding drum. The device according to the invention comprises a guide, preferably with a laying arm, via which the winding material of the winding drum is transferred by winding in a particularly linear back and forth laying movement of the laying arm. In addition to the laying arm, the guide may comprise a carrier, wherein the laying arm and the carrier are coupled to one another via a slide rail mounting. Furthermore, the device according to the invention has an adjusting device for moving, in particular for vertical lifting and axial displacement, the guide relative to the winding drum. Preferably, the adjusting device is formed by a robot that can set the guide in all three-dimensional directions. In addition, the device according to the invention has a control and / or regulating device which is coupled to the adjusting device and which provides the guide in accordance with the abovementioned method steps of the turning operation of the winding method according to the invention. It should be understood that the control routine should be designed to implement the method steps. Furthermore, the invention relates to a device which can be combined with or is independent of the device defined above for winding a strand-like winding material, such as a continuously extruded tube, preferably made of plastic, on a rotary, rotating winding drum, the device being designed in accordance with the method of the method according to the invention can. The device according to the invention has a guide, which transfers the winding material of the rotating winding drum in an in particular linear reciprocating movement substantially along an axial direction of the drum in a winding manner. The device according to the invention is in particular designed to rotate the drum about its axis of rotation at different angular speeds, wherein the axis of rotation of the winding drum is detected. Furthermore, the winding device according to the invention has a winding drum rotary drive and an angular speed control and / or control connected to the winding drum rotary drive. The angular velocity control and / or regulation sets the angular velocity of the winding drum in the axial course of winding of the respective winding material position as a function of the axial and / or radial setting position of the guide, in particular of the winding drum end of the guide, relative to the winding drum. The angular velocity control and / or regulation for multiple winding layers are operated at different angular velocity. In particular, the angular velocity is lower in the case of the winding layers wound first, while for the winding of later winding layers at the radially outer region of the winding drum, the angular velocity is set higher. The degree of reduction / increase in the angular velocity may be made dependent on the degree of asymmetry of the winding drum to be wound. In particular, winding drum individual data may be input to the speed control and / or control to adjust the corresponding optimum angular velocity. This can be based on experience. In this case, a distinction can be made between the axial asymmetries, such as the axial side flange impact, and the radial asymmetries, such as the drum core impact. The inventors recognized the radial asymmetric impact on the drum core as particularly critical.

In a preferred embodiment of the invention, the angular velocity control and / or regulation is provided with a sensor, such as a contactor, for detecting at least one predetermined position of the guide. As stated above, this displacement sensor or position sensor of the guide can be set to zero at the beginning of the winding layer. solve, wherein the progress of the winding either directly, in particular by means of the sensor or indirectly via the speed or the amount of the already wound winding material can be determined.

Preferably, the displacement sensor is arranged and fastened to the guide, wherein, in particular, the displacement sensor emits a trigger signal upon detection of at least one predetermined control position, so that the angular velocity control and / or control then changes the angular velocity. Preferably, at least one predefined setting position is defined when contacting the contactor with an inner side of a side flange of the winding drum. Preferably, the contactor along the edge to a bracket or a wheel, wherein a bearing axis of rotation of the contactor is pivoted away in the axial direction of a side flange, so that it can roll or run in contact with the rotating side flange. In a further displacement of the guide, the contactor can be pivoted from a passive position to an active position in which a trigger signal to the angular velocity control or regulation or can be delivered directly to the rotary drive.

The device according to the invention for winding the strand-form winding material can be designed such that the method steps of the method according to the invention with the device according to the invention are realized. The winding method according to the invention may also be designed such that the mode of operation of the winding device according to the invention is realized according to the method.

In a preferred embodiment of the invention, a laying arm of the device for winding in accordance with the invention can preferably be carried and placed by an actuating device, such as a robot, preferably in accordance with a control and / or regulation routine. The laying arm serves to channelize the stranded or wound material to the winding drum and to transfer it for winding, while the laying arm is moved back and forth, in particular substantially transversely to its longitudinal extent and linearly between the axial ends, such as the side wall flanges , The laying arm follows in particular stepwise the axial winding progress of the wound on the winding drum winding material.

The laying arm has a winding drum-side end, which accounts for a large part of the entire winding process in a contact, in particular rolling contact, with the winding drum or the already wound thereon winding layer and on each of which a respective side flange of the winding drum facing abutment region is formed on which the laying arm comes into abutting contact with one of the two side flanges especially when performing a turning operation. The contact can be formed as Anlageschleif- or rolling contact. Furthermore, the device according to the invention has a displacement sensor arranged on the wedge-side end, such as a contactor which emits a control signal, such as a turning operation triggering signal, at least when at least one predefined winding position, at least one triggering position for the turning operation, of the winding drum end is reached. The control signal is sent to an electronic control and / or regulating device, whereby a control for changing a specific control variable of the winding method can be triggered. Preferably, the control and / or regulating device performs a turning operation in which the old winding position is completed and the new winding position on the old winding position is started. In the turning operation, a change of direction of the laying movement of the laying arm is accompanied. According to the invention, the displacement sensor in the region of each abutment region has an actuating projection which protrudes in an unactuated position from the respective abutment region in forward or Herverlegebewegungsrichtung and preferably such movable, in particular pivotally mounted on the laying arm, that the respective actuating projection in its release position the respective contact area for contact with the side wall flange releases. The inventors have found that, for the winding-technically difficult turning or wall operation, the placement of the winding drum-side end and thus of the laying arm relative to the winding drum is essential in order to be able to realize higher winding speeds of more than 80 m / min. In particular, the timing at which distance to the side wall flange of the winding drum and when the turning operation is triggered and terminated, is important to realize a faultless completion of the spiral or winding layer and rebuild a solid winding layer base. The contactor, with its actuating projection projecting in the direction of displacement movement, realizes triggering of the control signal prior to reaching the laying movement limiting outer position of the laying arm achieved when the winding drum end of the laying arm contacts the sidewall flange of the winding drum stands. The yielding, in particular rotatable actuating projection allows the contact of the winding drum-side end with the Seitenwandflansch to. In a further development of the invention, in its release position, the relevant actuating projection is recessed in a vertical view into the laying arm, in particular in a housing structure of the laying arm. The laying arm may comprise a transport space limited in particular by plates, preferably completely closed, in which a pivot axis of the actuating projection is arranged, and the respective actuating projection has disappeared on reaching the side flange wall. Preferably, an actuating outer side of the actuating projection comes into sliding contact with the Seitenflanschwand, wherein in particular the operating outer side of the respective actuating projection is substantially flat and planar. The actuation outer side of the respective actuation projection is contour-adapted to an outer surface of the abutment region, so that in the release position the actuation outer side lies substantially free of excitation substantially in the plane of the outer surface of the particularly planar abutment region.

In a preferred embodiment of the invention, the actuating projection in its unactuated position (neutral position) is at least half or around a whole winding material thickness and at most two Wickelgutstärken of the respective contact surface in Hinbzw. Herverleebewegungsrichtung ago. In this way, an optimized, preliminary triggering of the control signal can be achieved before the contact area of the laying arm comes into contact with the side wall flange. It is clear that the period and / or the winding path between triggering of the control signal and contacting the contact area can be adjusted by that triggering of the control signal is changed only after exceeding an adjustable amplitude of movement of the actuating projection from its unimpeded position.

In a further development of the invention, the laying arm has a Wickelgutabgabeöffnung at its winding drum-side end at which the winding material leaves the transport space of the laying arm, to be transferred then in particular guide or contactless of the winding drum. Advantageously, the displacement sensor on the laying arm is arranged closer to a substantially cylindrical drum core of the winding drum than the winding material output at which the winding material leaves the laying arm without guidance, under the exclusive influence of gravity and the internal winding force of the winding material. Preferably, the displacement sensor is arranged in the vertical direction below the winding material delivery, wherein in particular the winding material extends without contact on the components of the displacement sensor over to the winding drum. In a preferred embodiment of the invention, the laying arm according to the invention comprises a sword-shaped housing, which is preferably formed of two mutually parallel, extending in the longitudinal direction of the laying arm housing plates delimiting a transport space of the laying arm extending from an actuator-side base portion to the winding drum end of the Laying arms extends. The winding material is passed through the transport space extending in the longitudinal direction completely through the laying arm until it reaches a winding material discharge opening. The housing plates in particular have an outer surface, which preferably lies in a vertical plane. The abutment region where the winding drum-side end comes into abutting contact with the side wall flange of the winding drum is formed at an axial end portion of the outer surface of the respective housing plate.

The contact area can be formed by a particular demountable wear plate, in particular of a material of lower friction, such as polyamide. The wear plate is preferably arranged interchangeably at the axial end portion of the two housing plates, in particular screwed.

In a further development of the invention, the contactor has a relative to the laying arm fixedly mounted pivot axis. The pivot axis is rotatably mounted on the housing of the laying arm in the interior of the transport space. The pivot axis remains stationary in each operating position of the actuating projection within the transport space of the laying arm. The pivot axis preferably extends substantially in the vertical direction, so that the respective actuating projection of the contactor is pivoted substantially in a horizontal plane.

In a preferred embodiment of the invention, an additional rotary motion sensor accesses the pivot axis of the contactor, so that in particular after exceeding a predetermined pivoting amplitude of the respective actuating projection, the control signal can be generated and delivered.

To generate the control signal, a pivoting movement transmission mechanism is housed, in particular within the transport space of the laying arm. The pivoting motion transmission mechanism serves to transmit the pivotal movement of the contactor away from the winding drum end to the base end of the laying arm, preferably without transmitting the motion by conversion to an electric field. - Ronic signal is realized. Only at a distance from the winding drum end, an electrical signal generator can be arranged, which is preferably disposed within or optionally outside the transport space of the laying arm, and generates and forwards the control signal based on the transmitted pivoting movement. Preferably, the pivotal movement transmission mechanism is realized by an angular gear which transmits the pivoting movement of the substantially vertically extending, actuating projection-side pivot axis of the contactor to a transmission shaft extending in the longitudinal direction (horizontal direction) of the laying arm.

In a further development of the invention, the actuating projection-side, in particular substantially vertically extending pivot axis of the contactor is biased such, in particular spring-biased that the actuating projection is always forced by its respective release position in the unactuated neutral position. Preferably, the transmission shaft is at least two parts, so that a shaft axis side shaft portion of a pivot axis remote shaft portion is non-destructive disassembled. The division is used for the modular replacement of the entire winding drum-side end of the laying arm to adapt the latter to different strong winding goods can.

In a development of the invention, the contactor has a closed ring structure forming a bow shape. Preferably, the bracket is realized axially symmetrically. In the unactuated position of the contactor, the symmetry axis of the ring structure coincides in the unactuated position of the contactor with the longitudinal direction of the laying arm. The two actuating projections are part of the bow-shaped triangular structure. The triangular structure is preferably realized isosceles, wherein a respective corner of the corner of the triangular bracket shape is rounded off the respective actuating projection. The same legs are arranged at an angle of less than 35 ° to each other, preferably about 30 °.

It is clear that the device according to the invention and the method according to the invention are designed in accordance with the devices and methods 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) could be.

In a preferred embodiment of the device, the carrier may be designed merely to provide an engagement region for attaching the actuating device or a handling device, such as of the robot, to form. Preferably, the carrier has a rail for a rail carriage arrangement. About a winding drum side end of the laying arm, the winding material of the rotating winding drum in the axial, in particular linear, forward and Herverlegebewegung the laying arm is transferred by winding. Preferably, the axial reciprocating motion is purely translationally linear and aligned substantially parallel to the axis of rotation of the winding drum. In particular, the winding drum-side end describes the axial linear back and forth transfer path between the two opposite side flanges of the winding drum. Facing away from the winding drum, the laying arm has a receptacle for accepting the winding material, which in particular continuously leaves an extrusion station. The receptacle can be formed, for example, by a star-shaped arrangement of several, in particular four, free-running rollers. The receptacle may additionally have a support structure, on which, for example, electronic components, but also pneumatic damping systems for the storage of the laying arm can be maintained.

The winding device according to the invention has in particular a laying arm bearing, which leads the laying arm in particular axial laying direction relative to the carrier. The winding device according to the invention preferably has a restoring or pretensioning device, which generates a particularly elastic, in particular substantially axially directed, restoring or biasing force, in particular in the case of a deflection of the laying arm, in particular from a neutral position of the laying arm relative to the carrier, in particular due to the axial growth of the winding position on the winding drum and tells the laying arm to laterally press the laying arm against the last laid on the winding drum winding loop.

The restoring device and the laying armature tension the laying arm in such a way that it is pressed against the winding, in particular the winding loop last laid, in an axial manner, in particular at its winding drum end. The greater the deflection of the laying arm relative to the carrier, the stronger the restoring force causing the axial prestress.

In the neutral position preferably no restoring force acts on the laying arm and thus on the winding loop last laid. The restoring force generated by the restoring device preferably acts constantly on the winding loop last laid during the process. velvet moving back and forth movement of the laying arm. The restoring force and thus the constant axial biasing of the winding drum-side end of the laying arm against the winding loop press the last-laid winding loop axially against the immediately adjacent winding loop, resulting in a compact, gap-free winding structure. The resilience in the laying direction realized by the laying armor combined with the elastic restoring bias against the laying direction allows for a change in the position of the laying arm caused by the gradually developing winding on the winding drum. During winding according to the invention, the laying arm does not carry out any actively defined, in particular controlled setting procedure, but constantly adapts flexibly to geometric features and material-specific characteristics of the winding. In a further development of the invention, a particularly reliable automation of winding at high Forderungs- and winding speeds of up to 100 m / min and beyond can be achieved. In addition to the translational flexible mounting in the laying direction of the laying arm can be stored flexibly in a vertical direction.

The laying arm support may preferably allow a purely translational adjustment of the carrier-side end of the laying arm and optionally a purely translational vertical movement of the carrier-side end of the laying arm. In addition, if necessary, the laying arm could carry out a pivoting movement of the laying arm about the carrier-side end of the laying arm by means of a corresponding carrier-side laying arm pivot bearing, wherein both a pivoting movement in an axial plane and in a vertical plane can be permitted. This shift arm pivot bearing must allow a swing amplitude of only a few degrees, in particular less than 20 °. The longer the longitudinal extent of the laying arm, the lower the pivoting bearing amplitude needs to be designed in the vertical direction and the horizontal direction.

In a preferred embodiment of the invention, a winding drum side end of the laying arm, which may be formed, for example, as freewheeling engagement wheel, carried out such that the winding drum end due to the restoring force in the axial reciprocating movement, in particular during the entire reciprocating movement in one in particular continuous lateral contact with an at least circumferential section-wise free lateral side of the last-positioned winding loop, so that in particular the laying arm depends on the axial growth of the winding to be laid, that is to say depending on the axial extent. Steering is deflected from the neutral position, for example, gradually to the axial extent of a winding loop in the axial direction of laying. Corresponding to the axial deflection, a restoring pressure force is generated by the restoring device, which is communicated via the winding drum-side end of the laying arm of the lateral side of the last-laid winding loop.

In a preferred embodiment of the invention, the return device comprises a particular controllable by the control and / or regulating device or adjustable suspension, which generates with appropriate deflection of the laying arm from the neutral position to a deflection elastic restoring force, in particular calculated and adjusts. It is clear that a controllable suspension can already generate a restoring force, without a deflection of the laying arm is accompanied by a neutral position. The restoring force is oriented such that its effective direction is parallel to the axial laying direction, in particular parallel to the axis of rotation of the winding drum. Thus, the back-up device presses the winding drum-side end against the last-placed winding loop, the effective direction of the restoring force of the laying direction is opposite.

The restoring force is preferably only used to bias the laying arm in the axial direction against the winding and to support it. The laying arm is reset relative to the carrier again, preferably realizes a holding device holding the carrier, such as a robot which tracks when exceeding a deflection threshold or a maximum restoring / V orspannkraft the carrier relative to the deflected laying arm.

In a preferred embodiment of the invention, the rear part device is formed by a pneumatic actuator, in particular by a pair of pneumatic actuators, one of which is responsible for generating the restoring force in each case in an axial laying direction. The pneumatic actuator can be coupled to a control and / or regulating device to obtain operational or winding-related additional control signals to actively increase or decrease the restoring force and thus the biasing force against the already adjusting amount according to the axial deflection. Preferably, the return device is connected to a control and / or regulating device, so that the restoring force and thus the biasing force during the winding substantially in a fixed limit range, in particular is kept constant.

During winding, the restoring force is generated step by step due to the yielding laying arm mounting. The restoring force can be reset stepwise by exceeding a threshold limit of a border area, without causing the restoring force / bias to disappear, so that the restoring force always remains within the predetermined limits. A lowering of the restoring force is realized by corresponding tracking of the carrier relative to the laying arm.

In a further development of the invention, the rear part has a control and / or regulating device for adjusting the Rückstellkraf orspannung example by adjusting the spring property of the return device and / or a controller for adjusting the Auslenkamplitude of the laying arm. The respective control and / or regulating device may be coupled to a sensor which detects the deflection range of the laying arm from the neutral position and notifies the control and / or regulating device, such as a microcomputer. The microcomputer can, for example, set a desired deflection at a constant spring property of the restoring device, in accordance with which a control process is initiated.

In one embodiment of the invention, the restoring force is adjustable. For example, this is realized in that the carrier is tracked relative to the laying arm, which is supported on the laid winding, in particular on the winding loop last laid. For this purpose, the winding device according to the invention comprises in particular a handle or adjusting device, such as a robot, with at least two, preferably three, axes of movement, preferably in a vertical axis of movement and in a horizontal axis of movement in the laying direction of the laying arm, in particular parallel to the axis of rotation of the winding drum. The actuator provides the support relative to the laying on the laid winding support arm, whereby the force acting between the laying arm and the carrier elastic restoring force can be increased or decreased. Preferably, a control and / or regulating device for the winding device is provided, which adjusts the restoring force and in particular causes a tracking of the carrier relative to the displaced by the winding increase Verleger arm by means of the actuator only when the Ver legearm has exceeded a predetermined Auslenkweg or Auslenkschwelle along the carrier.

Preferably, the winding device comprises a tracking device, according to which the carrier is tracked in the axial laying direction after the structure of the elastic restoring force according to the increase of the winding in the axial direction. For this purpose, the tracking device has the actuator holding the carrier.

In a preferred embodiment of the invention, the laying support is formed by a carriage-rail arrangement. The slide-rail arrangement ensures a linear guide of the laying arm relative to the carrier, which is guided substantially parallel to the axis of rotation of the winding drum relative to the carrier. The carrier side, the rail is formed, while Verlegearmseitig the carriage is realized. It is clear that the rail can also be arranged Verleger armmseitig, while the carriage is on the support side. The rear part device is connected between the carriage and the rail, so that the corresponding power transmission points of the reset device are arranged on the carriage and on the rail. The laying bar of the laying arm is fastened to the carriage, while the handling device acts on the rail of the carrier in order to provide readjustment of the carrier with respect to the laying arm.

In a preferred embodiment of the invention, the winding drum-side end is mounted such that at least a part, preferably for the entirety of the back and forth laying movement in particular up to the laying direction change the winding drum end to form a substantially axial lateral contact with a free lateral side of the last the winding drum wound winding loop is driven by the axially extending winding position along the laying path. In this way, a correctively flexible behavior of the laying arm required for the automation is realized which already comes very close to the manual manipulation of an experienced operator, whereby in particular geometric imbalances of the winding drum or the winding do not impair an automated winding process. The winding drum-side end is preferably formed by a freely rotatably mounted on the laying arm wheel, of which at least a portion of the side portion projects beyond the laying arm in order to come into contact with the still free lateral side of the last wound winding loop, and in the direction of rotation only the winding drum or is rotated by the already lying on the winding drum winding. In the laying direction, the wheel is taken along by the constantly axially growing winding position along the laying path and moved axially. At the same time, the wheel rolls on the winding drum or the already completely laid winding position, at least under the influence of the weight of the laying arm.

Furthermore, a preferred embodiment of the invention relates to an adjusting or releasing device which, at least during the laying movement near the side flange of the winding drum, inclines the laying arm away from the one side flange in a "positive" angle of attack for the horizontal radial extent of the one side flange and the laying arm in the course the back and forth laying movement towards the opposite side flange in a "negative" angle of attack from the other side flange inclined inclined. The actuating device is preferably formed by the handling device, such as the positioning robot, which, in order to operate the desired pivoting movement about the winding loop contact, constitutes the carrier. The pivot axis of the pivoting movement is preferably in the region of the winding drum-side end of the laying arm. The pivot point can migrate along the forward and Herverlegewegs. It is sufficient to set a clearance angle of 1 ° to 20 °. Corresponding to the free-setting angle, the rotatable laying direction of the laying arm defined by the laying arm position is also inclined with respect to the axial direction, whereby the angle of inclination at the axial ends of the reciprocating movement is correspondingly greatest and in the course of the to and fro laying movement, such as Free-fall angle, decreases and disappears about halfway laying and then gradually increases in particular gradually.

In a preferred embodiment of the invention, a laying arm for vertical positioning of the laying arm is provided relative to the winding drum for the proper operation of the laying arm especially in a change of direction of the back and forth. The Verlegearmstelleinrichtung cooperates with a displacement sensor for detecting at least a predetermined position of the laying arm along the laying path, wherein optionally the displacement sensor causes upon reaching the at least one predefined position, the Verlegearmstelleinrichtung, the laying arm by at least about half the thickness of the winding material, preferably by about a winding material or in order to lift away more than one winding material thickness, and at most by a factor of two times the winding material thickness away from the winding drum or away from the winding layer already laid thereon. The laying Gearmstelleinrichtung may have a particular vertical pivot bearing for the laying arm, wherein a pivot axis of the laying arm is arranged on the carrier side. The pivot bearing can be realized, for example, in that a winding drum-side laying arm blade is pivotable relative to the carrier-side laying arm base in the vertical direction. Furthermore, the laying arm adjustment device can have a lift for, in particular, vertical lifting of the pivot axis in the vertical direction, wherein the lift is formed, for example, by the handling device, such as the setting robot, which accesses the carrier in order to lift the carrier together with the laying arm pivot axis vertically linearly. In order to take the pivotable winding drum-side end when lifting, the pivot bearing has an abutment stop, which limits a lowering of the winding drum-side end of the laying arm. The pivot bearing allows on the one hand a flexible contact sequence of the winding drum side end of the already placed winding layer and thus a free contour following the already laid winding layer and its radial imbalances, on the other hand limited the investment stop lowering the winding drum end from the support on the winding position by at most half Wickelungsgutstärke , the winding drum end should come between two adjacent adjacent winding loops.

The laying arm is guided in the laying direction relative to a carrier. Upon deflection of the laying arm from a mounting position relative to the carrier, a restoring force directed in the axial laying direction is generated which acts against the winding placed on the winding drum.

The method according to the invention is preferably defined on the basis of the abovementioned operational and / or functional aspects of the winding device according to the invention. In a preferred embodiment of the invention, the device for winding the strand-like winding material has a laying arm, on which the winding material of the rotating winding drum is transferred in a particularly linear reciprocating movement of the laying arm. Preferably, the back and forth laying movement is limited by the side flanges of the winding drum. The direction of the back and forth laying movement can be predominantly parallel and / or slightly inclined to the axial direction. The winding device has an active laying arm adjusting device for vertically positioning the laying arm relative to the winding drum, which in particular can lift and lower the laying arm only in the vertical direction. The winding device comprises a displacement sensor for detecting at least one predetermined position of the laying arm, wherein upon reaching the at least one position preferably via a control and / or regulation, the laying arm is caused, the laying arm by about at least half a thickness of the winding material, preferably at least about one Wickelgutstärke, and to remove at most a twofold of the winding material thickness of the winding drum or the winding already laid on away, especially in an exclusive vertical movement to lift. In some cases, a lifting of over two or three times the winding material thickness, in particular empirically of over 30 mm is necessary. The vertical lifting of the laying arm, in particular of the winding drum end, for the change of direction of the forward and Herverleebewegung be limited insofar as the winding drum end to be taken after laying the first winding loop of the new winding position of the winding loop in a substantially axial Verleebewungsungsrichtung to the Drive arm to drive for the moving back and forth.

In particular, the laying arm adjusting device provides exclusively vertical lifting movement to initiate the directional change of the reciprocating motion, and subsequently, after the first winding loop of the new winding layer has come in lateral engagement with the raised winding drum end of the laying arm, the laying arm adjusting device returns the laying arm as far back settles until the winding drum-side end in particular either rolling or sliding comes in a radial contact to the completed winding position.

In a preferred embodiment of the invention, the displacement sensor is arranged on a winding drum-side end of the laying arm.

Preferably, the predefined position corresponds to the end of the forward and herverleebewegung. Preferably, the at least one predefined position when contacting the contactor is defined with an inner side of a side flange of the winding drum. Alternatively, the end of the reciprocating motion may be accompanied without structural contact with the side flange of the winding drum, for example, by achieving a certain minimum separation of the winding drum end from the side flange, which may be, for example, between about two times the winding material thickness or about one winding material thickness or less.

In a preferred embodiment of the invention, the displacement sensor has a freely rotatably mounted wheel, the bearing axis of rotation in particular in the axial direction of the side flange of the winding drum is pivotally away, whereby the triggering of the electrical control signal can be achieved. The wheel of the displacement sensor is rotatably mounted in such a way that it can roll in contact with the rotating side flange and can be pivoted in the axial direction from a passive position to an active position in a further displacement of the laying arm, in which the electrical control signal optionally via a controller and / / or regulation of Verlegerearmstelleinrichtung is communicated.

Preferably, the freely rotatably mounted wheel of the displacement sensor is located at the winding drum end of the laying arm in the region of a 12 o'clock position with respect to the winding drum, in particular under the influence of the weight of the laying arm on the winding drum or on an already laid winding position substantially tangentially.

In a further development of the invention, the winding drum-side end of the laying arm is designed to stand in the forth and Herverlegebewegung, in particular at least when reaching the predetermined position, in a continuous lateral contact with a free lateral side of the last laid on the winding drum winding loop. The winding drum end loses contact with the winding position upon removal from the winding and remains in the non-contact position until the winding drum end ceases by forming the lateral contact with the free lateral side of the new last laid winding loop for commencing the reciprocating movement the change of direction is taken. In a preferred embodiment of the invention, the Verlegearmstelleinrichtung has a pivot bearing for pivoting a winding drum-side end of the laying arm, in particular only in a vertical plane. The pivot bearing allows a relative pivoting movement between the laying bar of the laying arm and the laying arm base, which in turn is movably mounted on the carrier of the winding apparatus via the laying arm, in particular linearly substantially along the axial direction of the winding drum. On the carrier handles the handling device, such as the positioning robot, which is responsible for the vertical movement for lifting the pivot axis of the pivot bearing. The handling device can also be responsible for moving the carrier in the direction of the back and forth movement, so that the carrier can follow the laying arm leading by the axial winding increase.

Preferably, the Verlegearmstelleinrichtung has a lifter for particular linear lifting and / or lowering the pivot axis of the pivot bearing, wherein the lifter can be realized in a component union by the handling device, such as the positioning robot. Furthermore, the laying arm adjusting device may have a damper for damping the pivoting movement.

The laying arm support may comprise a carriage-rail arrangement, according to which the laying arm is guided linearly in the laying direction relative to the carrier. The axial direction is defined by the axis of rotation of the winding drum. The rotatable laying direction may be parallel to the axial direction, in particular depending on the position of the laying arm along the laying path and / or inclined to produce a free running angle of the laying arm, in particular less than 20 ° with respect to the horizontal radial extent of the side flange of the winding drum. The carriage is designed Verlegearmseitig, the rail is realized carrier side. A handling device, such as a positioning robot, advances the carrier, following the laying arm, and serves to reduce the increasing displacement of the laying arm, caused by the axial growth of the winding layer and always leading past the advancing carrier. The restoring force serves to constantly press the laying arm against the last-laid winding loop and in particular to maintain a bias against the winding loop and thus the winding loop contact when the handling device tracks the carrier following the laying arm. The carrier may only be tracked so far that continues to remain a sufficient biasing force on the laying arm against the last-placed winding loop.

The winding device 1 serves to wind a continuously extruded from an extrusion, not shown, plastic tube 3, such as a so-called cable protection tube on a winding drum 5, wherein a uniform possible winding without space between the individual winding loops 17 and with a substantially constant winding pitch of a plastic pipe width per Rotation is to be achieved, as shown for example in Figures 1 to 4b.

The winding drum 5 comprises a substantially cylindrical drum core 7, at the two axial ends in each case a lateral, extending in the radial direction side flange I Ia, I Ib is attached. Concentric with the rotational symmetry of the winding drum 5, a rotation axis 13 of the winding drum 5 is stationary (with respect to a reference bottom B, on which the winding device 1 is), around which the winding drum 5 for Performing the winding process rotates. The axis of rotation 13 defines an axial direction, to which reference will also be made in the following to define movements of moving components of the winding device 1.

For economic reasons, the standardized winding drum 5 is often made of wood, wherein the drum core 7 and the side flanges I Ia, I Ib can deviate slightly, but not negligibly from an ideal symmetrical shape. The cylindrical drum core 7 may have radial impacts, while the side flanges I Ia, I Ib can form Axialunwuchten. Also winding drums 5 made of other material, such as plastic, often deviate from an ideal symmetric rotational shape at random or due to production.

As shown in Figure 1, the extruded plastic tube 3 is already wound in an initial winding position by more than the axial half of the winding drum 5 to the drum core 7. In the following, the winding loop, which has just been applied last to the drum core 7, shall be provided with the reference numeral 17. The winding loop 17 has, until the next winding loop is completely encircling and has applied laterally, a circumferential portion free axial lateral side 18, to which reference is made in the following mainly at an approximately 12 o'clock circumferential location (contact with the engagement wheel 43) shall be.

The plastic pipe 3 is extruded continuously cylindrical along its extension and may have an outer diameter of 5 mm to 30 mm or 40 mm. The thickness of the plastic pipe 3 may be about 10% to 60% of the outer pipe radius. The plastic pipe 3 is continuously formed in an extrusion station (not shown) and passes through a cooling line (water bath) in the winding device 1, which may be preceded by a plastic pipe (3) buffer system (not shown), through the different conveying speeds of Plastic tube 3 to be compensated in the longitudinal direction during the extrusion process and during winding. The buffer system, not shown, may for example be designed as a vertical pendulum, which can compensate for the vertical displacement of a diverter wheel too little / too high speed of the winding device 1 relative to the extruding device by the guide wheel occupies a higher / lower vertical position. In this way, a buffer line for the extruded plastic pipe (3) can be achieved for a continuous manufacturing process before it enters the winding device 1. The winding device 1 according to the invention essentially consists of four main components, namely a carrier 23, a rear part device 61, a positioning robot 71, which is indicated only in FIG. 5, and a laying arm 27 according to the invention.

The laying arm 27 according to the invention has the shape such as a chainsaw with a Verlegerearmbasis 28 (actuator / motor base) and a laying blade 29, which extends from the Verlegerearmbasis 28 substantially in the horizontal direction to the winding drum 5 and these touches directly or indirectly. The laying arm base 28 has on its side facing away from the winding drum 5 a receptacle 21 (FIGS. 6, 9 and 10) for accepting the plastic pipe 3 which in particular leaves an extrusion station continuously. The receptacle 21 comprises pairs of rollers 25 arranged in a star shape which delimit a threading opening to ensure a horizontally and vertically guided threading of the plastic tube 3 in the laying arm 27. The laying arm base 28 is mainly formed by a profile support 57 which is composed of a plurality of mutually joined support plates. Functional components of the winding device 1, such as a microcomputer, actuators, etc., can be attached to the support plates.

The carrier 23 movably supports the laying arm 27 and, in the illustrated embodiment, has a rail 51 to which a gripping arm of the setting robot 71 is attached. The rail 51 cooperates with a carriage 53 of the laying arm base 28 so that the laying arm 27 can be reciprocated along the linear carriage path.

The laying blade 29 extends predominantly in a horizontal direction, approximately perpendicular to the axial direction 13 of the Verlegerearmbasis 28 away to the winding drum 5, wherein the laying arm 27 is dimensioned so that in the longitudinal direction over the drum core 7 (to about in the axial center) protrudes (considered in lifting direction A).

The laying blade 29 has two vertical, mutually parallel guide and holding plates 31a, 31b. Between the two holding and guiding plates 3 a, 31 b, which have a substantially constant vertical width in their essentially horizontal extension direction, a guide gap is formed for forming a transport space 32 for the plastic tube 3. In order that the plastic tube 3 can slide reliably from the receptacle 21 along the laying arm 27 between the holding and guide plates 31a, 31b, guide rollers in the guide gap can be rotated on the holding and guiding plates 31a, 31b. be stored and form a location-defined guide channel through the transport space 32 therethrough.

At a winding drum-side end 33 of the laying arm 27, a winding material delivery 34, in particular in the form of a pair of delivery rollers 35 with horizontal axes of rotation is still stored in the transport space 34, which ensure guided delivery of the plastic pipe 3 from the winding drum-side end 33 of the laying arm 27 to the winding drum 5. Between the laying arm base 28 and the winding drum end 33 extends an arm or striven-shaped support structure 30. The structure 30 may be bounded laterally by vertically arranged plates and limit the transport space 32. On the support structure 30 a plurality of guide rollers for performing the wound Wick are rotatably supported.

On a top side of the winding drum-side end 33, a displacement sensor 36 is positioned in a first embodiment of a contactor 37. The contactor 37 comprises a freely rotatably mounted contact wheel whose axis of rotation is arranged vertically. Another known from the prior art displacement sensor can be used. 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 1 lb and the opposite right side flange 11a, in which the axis of rotation lies in a guide gap of the laying bar 29. Preferably, as soon as the contact wheel of the contactor 37 comes into engagement with the radial inner side 41 of the respective side flange 11a, 11b, the contact wheel, in particular its vertical axis of rotation, is deflected in the axial direction, because the contact wheel at the winding drum end 33 of the laying arm 27 in FIG axially projecting axial directions and is pivotally mounted on the laying arm 27 for axial deflection. During axial deflection of the contact wheel, the contactor 37 outputs an electrical contact signal to a control and / or regulating device (not shown), 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 transmitted immediately after the movement of the contact wheel from its non-active center position or with a path-dependent delay after reaching a predetermined pivoting amplitude.

At the winding drum-side end 33 of the laying arm 27, a contact region 38 is formed, at which the winding drum-side end 33 of the laying arm can come into sliding contact with the side flange wall 11a, 1b of the winding drum 5. For this, the pivot bearing 39 of the displacement sensor 34 is designed such that the contact wheel of the contactor 37 is connected is pivoted away at least to the level of the outside of the respective abutment portion 38, so that the actuating projection of the contact wheel is completely sunk in the lateral direction and the respective abutment portion 38 is released. An alternative displacement sensor implementation is described below.

On the underside of the winding drum-side end 33 opposite the upper side, an engagement wheel 43 is mounted so as to be freely rotatably mounted on the laying arm 27 whose axis of rotation lies substantially horizontally parallel to the axis of rotation 13 of the winding drum 5. The running surface of the engagement wheel 43 is in direct rolling contact with the driven drum core 7 or an already placed winding position. A freely accessible side region of the engagement gear 43 abuts when winding with a predominantly axial pressure biasing contact on the axial lateral side 18 of the winding loop 17 last laid.

The axial width of the running surface of the engagement gear 43 is dimensioned such that it is greater than half the outer diameter of the plastic tube 3, but smaller than the outer diameter of the plastic tube 3.

The laying arm 27 is pivotally mounted vertically via a carrier-side (23) pivot bearing, which is not illustrated in detail, wherein a carrier-side pivot axis S extends horizontally, at least as a function 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, a damping unit 45 is provided, which is fastened on the one hand to the carrier 23 and on the other hand to a projection 47 on the upper side of the laying bar 29. The damping unit 45 ensures a damped pivoting movement of the laying arm 27 about the carrier-side pivot axis S. A pivot stop (not shown) is provided, which limits pivoting of the laying arm 27 in the vertical plane down to the winding drum 5. The pivotal stop ensures that the engagement gear 43 does not press between two already laid winding loops and completely penetrates between them, in order to avoid contact engagement of the engagement wheel 43 with an underlying complete winding position. The pivoting mobility of the laying arm 27 and the position of the pivot stop are set relative to the laying arm 27 such that the engagement wheel 43 is in rolling contact in rolling contact with the cylindrical drum core 7 or the last laid winding position. The pivot stop stops but lowering the engagement roller 43 from at most the half strength of the plastic tube 3, so that a rolling contact on the last completely laid winding position is prevented.

The support 23 is displaceable relative to the fixed axis of rotation 13 or the stationary reference base B of a production hall by one of the positioning robot 71, which is fixedly mounted on the reference bottom B, the carrier 23 engages, holds and positioned according to the winding process control.

In Figure 5, the axes of movement of the positioning robot 71 are partially shown, wherein the positioning robot 71, the carrier 23 in the horizontal direction, which corresponds to the axial direction (rotation axis 13) and substantially the laying direction V, and in lift direction A can move linearly and wherein the positioning robot 71 the Carrier 23 can pivot about the lateral contact K (about the axis of rotation D).

The point of engagement of the engagement wheel 43 with the drum core 7 or the winding position already laid forms an actuating point at which the laying arm 27 is axially displaced axially relative to the carrier 23 by the axial increase of the winding position 15. This may be referred to as a flexibly responding following movement of the laying arm 27, which immediately follows the continuous axial laying of the winding loops 17 and the axial growth of the winding layer 15. A vertical pivoting movement about the pivot axis S due to the system of the engagement wheel 43 on the winding drum 5 and a radial growth of the winding layers realized a follow-up of the initially stationary support 23 mounted Verlegearms 27. The Nachgebebewegung of the laying arm 27 and the Nachstellbewegung the support 23 are with the double arrows V, A indicated in Figure 5.

The positioning robot 71 holds the carrier 23 by means of the rail 51, which cooperates with the carriage 53, which is formed by a base plate 55 and a profile carrier 57 extending downwardly therefrom. The carriage 53 and the rail 51 form a translatory bearing, the translational laying direction V is set substantially or approximately parallel to the horizontal axial direction (rotation axis 13). The carriage (53) rails (51) - arrangement gives the laying arm 27 a freedom of movement relative to the carrier 23 only in the laying direction V, so that the carriage 53 only in the laying direction V relative to the positioning robot 71, in particular its gripper arm (not shown) , can be relocated. The rail (51) sled (53) arrangement provides axial compliance for the laying arm 27. The axial compliance is provided by the degree of freedom of movement in the laying direction V. In order that the engagement wheel 43 does not lose contact with the lateral side of the last-positioned winding loop 17 during 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 and provides an elastic return or biasing force generated when the transfer arm 27 from a predefined neutral position relative to the carrier 23, in which no restoring forces of the restoring device 61 between the rail 51 and the carriage 53 act in the laying direction V, driven by the axial expansion of the winding layer 15, is deflected. The amount of the restoring force is greater, the greater the deflection of the laying arm 27 from the neutral position. The resetting device 61 is formed by a pair of pneumatic actuators 63, 65, the details of which are indicated in FIGS. 7 to 10. A pneumatic actuator 65 or 63 is active for generating the restoring force only 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 in the opposite laying direction V (of FIG Side flange I Ib to the side flange I Ia) is active.

If the laying arm 27 is displaced by the periodic, horizontal laying of the winding loop 17 in the laying direction V, then the end 33 of the laying arm 27 together with the carriage 53 displaces in the linear laying direction V relative to the rail 51, which remains stationary in its position for the time being uninfluenced until it is adjusted, for example, when exceeding a deflection threshold of the carriage 53 by the positioning robot 71, which reduces the restoring force of the return 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) pneumatically clamped, so that in the pneumatic actuator 63, 65, the pneumatically elastic restoring force is generated, which via the carriage 53 to the laying arm 27 is communicated and finally the sprocket 43 biases axially against the free lateral side 18 of the last wound winding loop 17. The axial return bias ensures that all the winding loops 17 are placed close together in the axial direction to achieve the desired uniform winding sequence, and can be flexibly adapted to geometrical and material-specific anomalies. It is clear that the pneumatic actuator 63, 65 can also generate independently of the laying of the laying arm 27 an actively controlled, pneumatic restoring force, for example by the pneumatic actuator via a control and / or regulating device, not shown, for example, depending on a predetermined operating condition is pneumatically activated. In order to realize the simplest possible structure, the pneumatic actuator 63 is uncontrolled and builds up (only) elastic restoring forces when the laying arm 27 is moved out of its neutral position in the laying direction V.

In order to keep the axial restoring force which presses the engagement 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 in a boundary region. For this purpose, an unillustrated position sensor is used, which monitors a predefined minimum and maximum Sollauslenkamplitude by means of a control and / or regulating device (not shown in detail). If this is exceeded or fallen short of, the positioning robot 71 follows the rail 51 following the deflection movement of the laying arm 27, wherein the Nachrückschritt can correspond approximately to a thickness of the plastic pipe 3. In this way, it is ensured that the elastic restoring force is reduced by the trailing of the rail 51 by the periodic structure of the deflection.

In order to realize the desired winding around the drum core 7 of the winding drum 5, the plastic tube 3 when winding around the drum core 7 as far as possible claimed in the longitudinal direction with a constant tensile prestressing force.

According to the invention, an electromagnetic brake, in particular an eddy current brake 67, is arranged on the carrier 23, in particular on the carriage 53, which can be moved from an active operating position, as can be seen in FIG. 10, into a passive operating position (see FIG. 9). The eddy current brake 67, which may optionally be provided and manipulated by an unspecified control and / or regulating device, serves to communicate the substantially uniform tensile prestressing force to the plastic pipe 3. As an example, the eddy current brake 67 may include two magnet rotors that rotate in an electromagnetically generated magnetic field, wherein the respective magnet rotor may be retracted and extended to adjust the electromagnetic braking force. To initiate sufficient frictional deceleration forces in the plastic tube 3, a toothed belt 72 is provided, which is around two pulleys of the eddy current brake 67th is curious. The timing belt 72 has transverse teeth to ensure a desired engagement with the plastic pipe 3 and the friction force transmission. In an alternative embodiment of the belt 72 may also be provided a longitudinally extending mountain-valley profile, which is shaped complementary to the plastic pipe 3.

The following describes how a new "winding" layer 15 "raised" in the radial direction of the winding drum 5 is initiated when approximately one winding layer has been completed on the drum core 7 or an already laid winding layer and a "new" layer is formed thereon. Reference is made in particular to FIGS. 2a to 4b.

FIGS. 2a and 2b show an operating state in which a first winding layer 15 is approximately finished on the drum core 7. The engagement wheel 43 runs on the cylindrical drum core 7, wherein the axial restoring force generated by the rear part 61 forces the winding loop 17 just laid down axially against the adjacent winding loop. Before now the last winding loop 17 of the first winding layer 15 is completed, the contact wheel of the contactor 37 comes into rolling engagement with the inside 41 of the side flange I Ia. With continuation of the winding process, the contact wheel is deflected horizontally, whereby the control signal of the contactor 37 is sent to a control and / or regulating device, not shown. This causes after receiving the control signal vertical lifting of the laying arm 27 in that the setting robot 71 lifts the carrier 23 and its rail 51 in lift direction A substantially no more than the thickness of the plastic pipe 3, wherein the not shown vertical pivot stop the laying arm 27th in vertical lifting direction entrains to lift the winding drum side end 33 of the laying arm 27 by slightly more than the outer diameter of the plastic pipe 3 on the winding position just finished 15. 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 pipe 3. By continuous winding is The plastic tube 3 is placed in the still remaining winding gap with the side flange 11a until the first winding loop of the "new" winding layer 15 forms.First, the freely accessible side region of the engagement wheel 43 comes in a lateral contact K with the lateral side 18 of the first winding loop 17 the newly applied winding position 15, wherein the rolling surface of the sprocket 43 in the short term still removed from the already completed winding position 15 is raised. Only after the first winding loop 17 entrains the engagement wheel 43 in the laying direction V, the engagement wheel 43 lowers, so that its rolling surface comes into rolling contact with the fully wound winding position 15. This operating state can be seen in Figures 4a and 4b, in which the sprocket 43 is on the one hand in rolling contact with the currently placed winding layer 15, on the other hand is biased with the uncovered side region in lateral contact K with the lateral side 18 of the first winding loop 17. In this operating state, the laying arm 27 is already crazy again in the axial direction relative to the carrier 23, as a result of which the restoring device 61 generates the restoring force which presses the engagement wheel 43 against the winding loop 17 which has just been laid. That the laying arm 27 is already deflected away from the axial end position is also apparent at the position of the contact wheel of the contactor 37, which is again in the passive operating state and no longer in rolling contact with the inside 41 of the side flange I Ia.

In Figure 6 it can be seen that the laying arm 27 is inclined in its axial end position shown in Figure 6 to the horizontal radial direction H _R at an angle α, according to which the laying arm 27, starting from the winding drum side end 33 of the right side flange 1 la away is inclined to the winding drum center. This ensures that the contact wheel of the contactor 37 has sufficient room for swinging out to generate and dispense the control signal without the end 33 of the laying arm 27 coming into contact with the inside 41 of the side flange 11a, 11b.

In the course of the axial laying movement from the right side flange I Ia to the left side flange 1 Ib decreases a (positive) angle α, so that approximately in the axial center of the winding drum 5, the longitudinal extent of the laying arm 27 coincides with the horizontal radial direction H _R , during the Laying arm 27 in the opposite axial Verlegeendposition in a (negative) angle of attack α in particular of the same size is also inclined towards the center of the winding drum 5. Also in this position, the contactor 37 can safely trigger by the contact wheel is swung laterally.

In both axial laying end positions of the laying arm 27, the radially extending side flange 11a, 11b does not interfere with the inclined laying arm 27. The above-mentioned, not shown, in particular on the structure 30 can be accommodated control and / or regulating device can be used exclusively for the angular velocity of the winding drum 5 in dependence of the radial and / or axial position of the guide (the laying arm 27), in particular its wickelmommelseitigen end 33, adjust. It is clear that the control and / or regulating device can also assume the above-mentioned control functions. Preferably, the control and / or regulating device is firmly connected to the base plate 55. However, other mounting locations for the control and / or regulating device may also be considered.

When laying the plastic pipe 3 on the winding drum 5, the leading end of the plastic pipe is first threaded through an opening in the side flange 1 1 of the winding drum 5 and immediately adjacent to the inside 41 of the side flange I Ia, I Ib manually by an operator for the first winding layer at a low angular velocity (see Figure 1 1; START) wound up, wherein the angular velocity U increases gradually.

Before the winding starts, the displacement detection of the laying arm 27 in the control and / or regulating device is initialized, namely set to "0". From this initialization of the laying process (at START according to Figure 1 1) begins a particular continuous detection of the position of the laying arm 27. After first windings of the winding layer 15 (eg., Figure 1) rest on the drum core 7, the winding speed U is at a maximum Winding speed U _max increases, so that from a variable or pre-fixed Stellpositon Xi for the first winding layer 15, the maximum winding speed Umax is reached. During the helical laying of the winding layer 15 in the so-called axial center region C of the winding drum '5 (see FIG. 6) between Xi and X ₂ , X ₅ and X ₆ , (FIG. 11) or between the axial setting positions P _a and P _b , (FIG. 6), the maximum winding speed U _{max should be} kept constant (see FIG. 11).

It is clear that the correct angular velocity of the winding drum 5 is decisive for the winding success. Of course, the control process based on the peripheral speed at the respective winding position 15 can be adjusted. In the description of the figures, the winding speed is referred to as the control quantity for the sake of simplicity. Reaches the laying arm 27, coming from the Stellmittelbereich C, the predetermined axial parking position X ₂ , or P _a or P _b , which can be determined for example by detecting the axial position of the laying arm 27 or by detecting the already wound winding length, the control triggers - And / or regulating device a so-called Seitenflansch- or turning operation, in which first the angular velocity is gradually reduced gradually, namely to a minimum angular velocity U _m in, which is to be kept constant during the further delicate wall operation K2-X4) (Fig. 1 1). If the wall operation is completed (at X4), in particular when reaching a parking position after the start of movement of the laying arm 27 to the opposite (Verlearearfernen) side flange I Ia or I Ib of the winding drum 5, the winding speed between X and X ₅ according to the previous winding speed decrease between X ₂ and X _{3 is} continuously steadily increasing and reaches the maximum angular velocity U _max in the setting position X ₅ , which may be predetermined or calculated during the winding process.

It is clear that FIG. 11 does not show the direction of the axial movement of the laying arm 27, but only the winding speed U as a function of an absolute, axial travel amount IX | from the START. The axial direction of movement of the laying arm 27 changes at the respective setting positions X ', X ", at the end of which the minimum angular velocity U _m remains constant.

In general, the adjustment positions can either be predetermined by input to the control and / or regulation means, or calculated during the winding process and changed according to the winding progress.

FIG. 12 illustrates the turning operation on the basis of a path-time diagram in which the axial displacement X is shown in relation to the time t. At the moment when the turning position is reached by the guide, the laying arm 27, the time to is decisive. According to FIG. 12, before reaching the turning point t _0, a stepped graphene shape can be seen, in which the stepwise advancement of the laying arm 27 in the axial direction with respect to the leading winding layer during the normal winding operation should be clarified. It is clear that no step shape is necessary, but also other curved paths are possible. It should be noted that axial restoring forces, which cause the laying arm 27 to be pressed against the free lateral side 18 of the last winding loop, are built up by placing the laying arm 27 relative to the carrier 23 of the guide winding. tion in the axial direction X is advanced by the winding progress; the coil winding, which builds up axially, presses the laying arm 27 against the elastic pretensioning device acting within the guide, as a result of which elastic restoring forces build up due to the relative movement.

Upon reaching the turning position Xo at the time to the toggle operation is triggered. If the turning position Xo achieved, the control and / or regulating device causes a vertical free travel of the laying arm 27 of the winding drum 5 away, which experience shows a radial clearance of 30 mm is sufficient to balance maximum Radialum balancing the drum core 7 of the winding drum 5. Essential in the free movement of the laying arm 27 is to always make the drum-side end 33 contactless to the last laid winding layer 15. During the radial free travel time t ₀ to t _{l5 are covered in} accordance with the approximately 0.8 revolutions of the winding drum 5, the laying arm 27 is not displaced in the axial direction and remains at the turning position X ₀ . Until the time ti, the axial distance (X) does not change.

Figure 1 1 and Figure 12 are related in so far as the reversal position Xo corresponds shown in FIG 12 is substantially the position X ₂ or X ₆ in accordance with Figure 1. 1 During the period t ₀ to t _1; while the laying arm 27 remains at the turning position Xo (X ₂ or X ₆ ), the angular velocity U remains unchanged.

From the end of free travel ti the carrier 23 and thus the laying arm 27 (the end 33 no longer rests on the laid winding layer) further in the axial direction towards the Seitenwandflansch I Ia, I Ib the winding drum 5 advanced to a complete concern of the winding drum side End 33 of the laying arm 27 on the Seitenwandflansch I Ia, 1 lb always during the entire cycle of the winding drum 5 to ensure. The axial advance path is illustrated in FIG. 12 by Xo to Xi. After completion of the advance at time t ₂ , the winding drum 5 can be further rotated by about 0.4 turns.

At the time (at the turning position Xo (X ₂ or X ₆ according to Figure 11)), the speed for the further advancement of the guide is reduced.

From the end of the advancement (t ₂ , X [), a position correction of the laying arm 27 or of the carrier 23 can be carried out in order, for example, to restore the restoring forces in the rail To adjust carriage storage or to change the position of the laying arm 27 relative to the winding drum 5. The correction phase may take about 0.6 revolutions of the winding drum 5.

At the end of the correction t ₃ , the guide, namely the carrier 23 together with the laying arm 27, is set in the direction of displacement movement opposite to the laying direction in order to make the laying arm 27 contactless with respect to the side wall flange 11a, 11b of the winding drum 5 , In this case, the return return path is approximately equal to the advancement path, but can also be realized larger or smaller, thus ensuring that the winding drum-side end 33 of the laying arm 27 no longer reaches the contact area of the side wall flange 11a, 11b of the winding drum 5. The return can take about 0.2 revolutions of the winding drum 5. At the end of Rückrückung I the laying arm 27 is lowered back to the already laid winding layer 15 and thus comes into rolling contact. During the lowering of the laying arm 27 until the time t ₅ , the carrier 23 of the laying arm 27 remains in the axial position, which in particular corresponds to a neutral position in which no restoring forces act. At time t ₅ , the newly laid winding loop passes into the lateral abutment contact with the engagement wheel 43 and takes the laying arm 27 in the direction of laying movement, which is to be represented by the downward-sloping shape of the graph. In order not to let the restoring forces become too large, as described above, the carrier 23 is tracked relative to the adjacent laying arm 27 by the positioning robot 71. At the earliest at time t ₅ should be started with the change of the angular velocity to U _max in order to achieve the fastest possible winding along the drum core 7.

In general, the axial displacement X refers to the actuating movement of the carrier 23, wherein the displacement of the carrier 23 by the positioning robot 71 and the flexible adjustment of the laying arm 27 due to the sliding bearing on the carrier 23 and the winding progress in the case is about the same, when the laying arm 27 is not supported on the side wall flange 11 a, 11 b of the winding drum 5 or the lateral side of the last winding loop.

Details of a preferred embodiment of the laying arm 27 according to the invention are shown in FIGS. 13 to 18, wherein the same reference numbers are used for similar or identical components of the laying arm 27 previously described with reference to the previous figures in order to facilitate the readability of the figure description. The laying arm 27 comprises three main components, namely the arm base 28, at which the winding material is introduced, the winding drum end 33, on which the winding material is discharged, and an intermediate elongate support structure 30, which forms the majority of the laying arm 27. The winding drum-side end 33 is releasably and interchangeably connected via interfaces 110, 111 with the support structure 30. In this way, it is sufficient, when changing the dimension of the winding material, only to exchange the winding drum-side end 33 for a dimension-adapted, while all other components (28, 30) of the laying arm 27 can be maintained. These other components are independent of the dimension of the winding material. Only the winding drum-side end 33 is winding material specific due to the contactor 37, which will be explained below as an alternative embodiment, and the winding material delivery 34 executed.

As can be seen from Figures 13 to 18, the contactor 37 is formed in an alternative embodiment without contact wheel, but realized with on the side flange wall I Ia, I Ib schleifend running actuator projections 101 a, 101 b. The actuating projections 101a, 101b are part of a closed bow or ring structure of the contactor 37, which in plan view has a triangular shape with two equal length long legs, which lie at an angle of about 15 ° to the longitudinal direction of the laying arm 27. The long legs extend to a connecting front short leg, which forms the free end of the contactor 37 and the winding drum end 33. Corners of the triangular ring structure are rounded.

The actuation projections 101a, 101b, together with the ring structure, are pivotably mounted about a pivot axis 100 extending in the vertical direction, so that the respective actuation protrusions 101a, 101b can be retracted so as to pivot with the respective sidewall flange 11a, 11b such that their corner area is level with the outer surface the abutment portion 38a, 38b and no distance projects laterally beyond the outer surface. In this release position of the respective actuation projection, the abutment region 38 of the winding drum-side end 33 of the laying arm 27 touches the inside of the respective side wall shrinkage 11a, 11b. If the laying arm 27 is moved away from the respective side flange wall 11a, 11b and the contact area 38 is released, then the ring structure of the contactor 37 automatically moves into its middle, unactuated position (see FIGS. 13-18) by means of a force means (not shown) , such as a spring, preferably a torsion spring. The spring preload can directly engage the ring structure or on a gear part, such as the pivot axis 100, etc. The contactor 37 is provided with an angle gear 103 for transmitting the pivotal movement of the vertical pivot axis 100, which is rigidly coupled to the ring structure, into pivotal movement about a transmission shaft 105 extending in the longitudinal direction of the laying arm 27. The translation of the angular gear 103 for transmitting the pivoting movement is preferably 1: 1.

A signal generator (not shown), which is arranged on the supporting structure 30 and which outputs an electrical control signal after the start of movement or after exceeding a predetermined swiveling amplitude of the ring structure, is communicated to the transmission shaft 105 in order to inform the control and / or regulating device that the turning operation is to be initiated. The control signal can be triggered immediately at the start of the swing or only delayed after reaching a predetermined swing amplitude.

The transmission shaft 105 is divided into two, with the path sensor-side shaft portion 107 coupled to the support (30) side shaft portion 109 by means of a releasable dog clutch 110 that allows disassembly of the front and rear shaft portions 107, 109 from each other. At the shaft portion 109 of the signal generator connects. In addition to the dog clutch 110, the guide and holding plates 31b and 31a form a separable interface 111 for separating a housing plate portion facing the winding drum 5 from a base-side housing plate portion.

The mounting interfaces (110, 111) allow the winding drum end 33 together with its functional elements, such as the Wickelgutabgabe 34, Abgaberäder 35, Kontaktgeberteile and decouple the mechanical communication of the contactor 37 toward the signal generator to the device of the invention and in particular the majority of Verlegearms invention 27 to adapt depending on the application for a certain sized winding material. It has been found that those components in the transport space 32 on this side of the mounting interfaces (110, 111) can be interpreted for a large number of different sized winding goods, but the winding drum-side end 33 is to be adapted to the winding material specific to the dimensioning. In particular, the winding material delivery 34 and the actuation projections 101a, 101b projecting from the abutment region 38 can be adapted to the winding material thickness.

Particularly advantageously, the purely mechanical realization of the contactor 37 up to the signal generator on the basis of releasable couplings, such as the dog clutch 110, so that no electronic signal transmission between the winding drum end 33 and the carrier side arranged control and / or regulating device is necessary. In this way, an exchange of the winding drum end 33 can be done purely mechanically, whereby even inexperienced operators can perform a change of the winding drum end 33 for adjusting the laying arm 27 to be wound winding.

The features disclosed in the foregoing description, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments.
