Description

Apparatus and method for winding a rope-shaped winding material

The invention relates to a device for a method for winding 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 conduit 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 space in stock. It is known to wind the winding material on a winding drum or reel, such as a flange, and to handle on site as needed. For reasons of production economy, the take-up operation directly adjoins the production process, in particular the extrusion, of the winding material, so that the just-extruded plastic material to be wound leaves a cooling station without being cut 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 geometrical irregularity of the winding drum, according to the state of the art, a winding of the winding material monitored and manipulated by an operator is 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 longer curing time, so that the winding property of the plastic pipe after and during winding due to changes in the material properties after extrusion. dieren hardly predict. Such individual winding parameters 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 shown that in the known winding automation processes there are ideal conditions for both the cable and the winding drum, which concerns in particular the geometry of the winding drum as well as the material properties of the winding material. Especially with wire winders are products of high material quality and uniform material properties, which is why higher cost is operated to use idealgeometrische, unbalance winding bobbins. 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 an apparatus and a method for winding a rope-like winding material such as a continuously extruded tube, preferably made of plastic on a winding drum, wherein an automation is to achieve at a manual intervention by an operator can be avoided as far as possible.

This object is solved by the features of independent claims 1 or 8.

Thereafter, a device for winding a strand-like winding material, such as a continuously extruded tube, preferably made of plastic on a winding drum is provided. The winding drum according to the invention comprises a support on which, for example, electronic components of the device can be arranged. The carrier may also be designed merely to form an engagement region for fastening a gripping arm of a positioning device or a handling device, such as a robot. Preferably, the Carrier a rail for a rail carriage arrangement. Furthermore, the winding device according to the invention has a laying arm mounted on the carrier, over the end of which the winding material of the rotating winding drum is transferred by winding in an axial, in particular linear, reciprocating movement of the laying arm. 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 wakkeltrommelseitige end describes the axial linear back and Herverlegeweg 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 also has 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 has a restoring or biasing device which generates a particular elastic, in particular substantially axially directed restoring or biasing force in particular at a neutral position of the laying arm relative to the carrier at a particular induced by the axial growth of the winding position on the winding drum deflection of the laying arm and the laying arm communicates to press the laying arm laterally 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, whereby 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 rear part 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. So that the rear-part device presses the winding-drum-side end against the last-laid winding loop, the effective direction of the restoring force is opposite to the laying direction.

The restoring force is preferably only used to bias the laying arm in the axial direction against the winding and to support it. Relocating the laying arm relative to the carrier again preferably implements a positioning device holding the carrier, such as a robot which, when a deflection threshold or a maximum return / biasing force is exceeded, tracks the carrier relative to the deflected laying arm.

In a preferred embodiment of the invention, the return device is formed by a pneumatic actuator, in particular by a pair of pneumatic actuators, of which one of the actuators 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 rear part 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 predetermined 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 restoring force / bias, for 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 is provided for the winding device, which adjusts the restoring force and in particular triggers a tracking of the carrier relative to the displaced by the winding increase Verlegearm 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 traced 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. The rear part device is connected between the carriage and the rail, so that the corresponding power transmission points of the return 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 rotationally driven by the already lying on the winding drum winding. In Laying direction, the wheel is taken along by the steadily growing axially 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 walk along the back and forth laying away. It is sufficient to set a free-standing 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 Verlegearmstelleinrichtung is provided for the vertical positioning of the laying arm relative to the winding drum for the proper operation of the laying arm especially in a change of direction of back and forth laying. 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 Verlegearmstelleinrichtung can a particular vertical pivot bearing for the laying arm have, wherein a pivot axis of the laying arm is arranged 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.

In a preferred embodiment of the invention, a winding material brake is arranged on the laying arm, which informs the winding material before reaching the winding drum, a braking force to bias the winding material to train. The braking force can be adjusted according to the operation in particular by a control and / or regulation.

Furthermore, the invention relates to a method for winding a strand-like winding material, such as a continuously extruded tube, preferably made of plastic on the winding drum. In the method according to the invention, the winding material of the rotating winding drum is transferred relative to a carrier by means of a back and forth laying movement of the laying arm. 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. Further embodiments are specified in the subclaims.

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

This object is achieved by the features of independent claims 8 or 13, which are of course combinable with the above-mentioned invention.

Thereafter, a device for winding a rope-shaped winding material, such as a continuously extruded tube, preferably made of plastic on a rotating winding drum is provided. According to the invention, the winding device comprises a carrier to which various functional parts of the winding device can be attached. Furthermore, the winding device according to the invention has a support arm movably mounted on the support with a receptacle for accepting the winding material leaving in particular an extrusion and a winding drum end, on which the winding material of the rotating winding drum at a particular linear back and forth movement of the laying arm along a rotational axis of the winding drum wound up to be handed over. The carrier receives the winding material on the receptacle, which may be formed for example by a cross-shaped roller assembly. The displacement movement of the laying arm is preferably purely translatory for each winding position in a horizontal plane. Since the winding layers are superimposed, a separate linear return path can be realized in each case in the vertical direction by one winding material thickness for each winding layer, wherein in particular the forward and herverlegeweg is not rigidly predetermined according to a fixed control routine, but rather flexible depending on the individual Winding installation course adjusts itself. For this purpose, the laying arm is mounted on the carrier in such a way that the winding drum-side end of the laying arm follows the axially expanding winding position to form a lateral contact with a free lateral side of the wound winding wound on the winding drum, at least in one part of the particularly linear reciprocating motion. According to the invention, the winding device does not set the winding drum-side end in accordance with a defined control routine, but provides the winding growth yielding freedom of movement for the laying arm, whereby geometric imbalances and changes in geometry during the winding process can be compensated. In contrast to the prior art, in which rigid control actuation systems implicitly require an ideal geometric winding drum, the winding device according to the invention achieves automation even when unpredictable geometry changes and geometric properties have to be considered. The winding drum-side end of the laying arm constantly contacts the winding loop last laid and is entrained by the latter, preferably by the laying arm an elastic force acting on the winding drum end against the last laid winding loop, thus even with imbalances and axial or radial strokes of the lateral contact is not lost in particular due to inertia between the last-laid winding loop and the winding drum end.

It should be understood that the winding drum end may also maintain radial contact with a drum core of the winding drum or with the already completed winding position. The required radial contact forces are preferably realized due to the influence of the weight of the laying arm with a corresponding pivot bearing for the laying arm on the support.

In a preferred embodiment of the invention, the laying arm is mounted on the carrier in such a way that the winding drum end temporarily loses contact with the winding for a change in the direction of the reciprocating movement, in particular in the formation of a next winding position, and so long without contact Winding remains until the winding drum-side end is taken along to form the renewed lateral contact of the free lateral side of the newly forming, first winding loop in the axial Verlegebewegungs- direction. Only at the two axial ends of the laying movement path is the permanent contact between the winding drum-side end and the winding position and / or the drum core canceled.

In a preferred embodiment of the invention, the winding drum-side end of the axial extension of the winding position compliant follows in particular continuously, by an elastic restoring or biasing force of a restoring or biasing means presses the winding drum end against the lateral side of the last laid winding loop. In this case, the elastic restoring force is substantially in the axial direction, in particular special parallel to the axis of rotation of the winding drum, directed that the substantially exclusively lateral forces are introduced from the winding drum side end in the last winding loop, so that the last-laid winding loop against the adjacent winding loop laterally, is axially biased. The elastic restoring force or axial prestressing against the last-laid winding loop is preferably realized by the restoring device, which may have, for example, a pneumatic actuator or another spring system. The return device can act between the carrier and the carrier arm movably mounted to the carrier.

In a further development of the invention, the winding drum-side end has a freely rotatably mounted on the laying arm engaging wheel. The bearing of the engagement wheel should be free of any other drive forces, but should only be placed in a rotational movement when it comes into contact with the winding drum or laterally with an already laid winding position. The sprocket may have a verlegearmbezogen fixed axis of rotation, which may be arranged substantially parallel or slightly inclined to the axis of rotation of the winding drum. In order to avoid a sliding contact between the laying arm and a side flange of the winding drum, the laying arm can be inclined in accordance with an angle of attack to the radially extending inside of the side flange. In this case, the rotation axis of the engagement wheel does not coincide with the rotation axis of the winding drum, but is inclined by a few degrees.

In a preferred embodiment of the invention, the engagement wheel has a circumferential cylindrical rolling surface, which runs on the cylindrical drum core of the winding drum or on an already laid on the winding drum winding position. In this case, the rolling surface of the engagement wheel presses on the drum core or the winding position under the influence of the self-weight force of the laying arm mounted pivotably on the carrier in the vertical direction.

Preferably, the engagement wheel projects in sections over the winding drum end such that a blank, freely accessible, lateral side region is formed, which is preferably a smooth flat surface lying in a vertical plane in the case of a disk-shaped engagement wheel. On the side region, the engagement wheel is pressed under the influence of the axial restoring force against the free radial lateral side of the winding loop last laid. The freely accessible side region of the engagement wheel can be dimensioned such that the lateral side of the winding material to form the lateral contact exclusively with engages the side area. The tread of the engagement wheel comes into rolling engagement with the radially underlying winding layer or drum core.

In a preferred embodiment of the invention, the laying arm is mounted on the carrier such that the winding drum end extends along a linear engagement path on the outer circumference of the winding drum core or on a winding position last laid on the winding drum in accordance with the gradually increasing axial extension of the winding layer to be wound around the winding material thickness gradually crazy. The engagement path may preferably be substantially at a 12 o'clock circumferential position to most effectively utilize the weight forces of the dead weight of the laying arm. Preferably, the laying arm lies tangentially on the engagement path under the influence of its own weight.

In a preferred embodiment of the invention, the laying arm has the shape of a sword. The shaft of the sword is the carrier side, while the tip of the sword protrudes towards the winding drum. The tip of the sword is in constant contact with the winding drum or already laid winding position, at least during the back and forth laying movement.

The laying arm may be formed by two substantially parallel plates whose longitudinal direction extends towards the winding drum and whose width direction is aligned in the vertical direction. The parallel plates can form a guide space or gap between them, in which the winding material is guided within the laying arm towards the winding drum end. The guidance of the winding material within the laying arm can preferably be formed by at least one in particular free-running roller and / or by at least one in particular freely running roller pair. The roller and / or the pair of rollers may be rotatably mounted on the plates.

Preferably, a pair of delivery rollers is preferably freely rotatably mounted on the winding drum end over which the winding material leaves the laying arm to be wound in the course of the winding drum without influencing a further mechanical structure such as the sprocket.

In a further development of the invention, the carrier-laying arm has a carriage rail arrangement through which the laying arm is guided in particular substantially parallel to a rotation axis of the winding drum relative to the carrier. Preferably attached to the carrier, the rails and the laying arm of the carriage, in particular, the restoring device between the carriage and the rail acts. The return device serves to generate an elastic spring force in order to bias the winding drum-side end against the last-laid winding loop.

In a preferred embodiment of the invention, the winding device according to the invention comprises a Verlegearmlagerung which leads the laying arm in a particular depending on the axial position along the laying path rotatable laying direction relative to the carrier in particular linear, and a restoring or biasing device relative to the displacement of the laying arm in the laying direction to the carrier the restoring arm informs a restoring or biasing force to urge the laying arm laterally, substantially axially against a last laid on the winding drum winding loop. 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 higher the deflection of the laying arm relative to the carrier, the stronger the restoring force of the return device acts. With this aspect of the invention, an optimally compact, tight arrangement of winding loop to winding loop is realized.

Furthermore, a preferred embodiment of the invention relates to an adjusting or releasing device which, at least during the laying movement, adjoins the laying arm near the side flange of the winding drum in a direction for horizontal radial extension of the one side flange. beautiful "positive" angle of the one side flange tending to tilt and the laying arm in the course of the back and forth laying movement towards the opposite side flange in a "negative" angle of attack tilted away from the other side flange away. 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, provides 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 Verlegearmstelleinrichtung 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. To take the pivoting winding drum end end when lifting, the Swivel bearing an investment 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 limits the investment stop lowering the winding drum end from the support to the winding position by at most half Wickelungsgutstärke , the winding drum end should come between two adjacent adjacent winding loops.

In a preferred embodiment of the invention, a winding material brake is arranged on the laying arm, which informs the winding material before reaching the winding drum of a braking force to bias the winding material to train. The braking force can be adjusted according to the operation in particular by a control and / or regulation.

Furthermore, the invention relates to a method according to claim 7. Thereafter, a strand-shaped winding material, such as a continuously extruded tube, preferably wound from plastic onto a winding drum by the winding material of the rotating winding drum is transferred over a mounted for a Her and laying movement laying arm. In addition, a winding drum side end of the laying arm is maintained in a constant lateral contact with a free lateral side of the wound on the winding drum windings of the winding material at least in a part of the particular linear back and forth laying movement, so that the winding drum side end of the axially expanding winding position follows.

It is clear that the method according to the invention can be designed in accordance with the operating function of the winding device according to the invention.

It is an alternative or additional object of the invention to overcome the disadvantages of the prior art, in particular an apparatus and a method for winding a strand-like winding material such as a continuously extruded tube, preferably made of plastic on a winding drum to provide automation reach, in which a manual intervention by an operator can be avoided as far as possible. This object is achieved by the features of independent claims 14 or 19, which can be combined with the features of the above-mentioned invention.

Thereafter, a device for winding a rope-shaped winding material, such as a continuously extruded tube, preferably made of plastic on a rotating winding drum is provided. The winding device comprises 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.

In Figure 1, the winding device according to the invention is generally provided with the reference numeral 1. 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 fixedly mounted (relative to a reference bottom B on which the winding device 1 stands) about which the winding drum 5 rotates to perform the winding operation. 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 laying arm 27, a return device 61 and a positioning robot 71 indicated only in FIG.

The laying arm 27 has a shape such as a power saw with a laying base 28 (actuator / motor base) and a laying blade 29 extending from the laying base 28 substantially horizontally to the winding drum 5 and contacting them directly or indirectly. The Verlegerearmbasis 28 has on its end facing away from the winding drum 5 a receptacle 21 (Figures 6, 9 and 10) for accepting the in particular an extrusion continuously leaving plastic ear 3. The receptacle 21 comprises star-shaped arranged pairs of rollers 25 which limit a Einfädelöffnung to a ho - To ensure rizontal and vertically guided threading of the plastic tube 3 in the laying arm 27. The laying arm base 28 is mainly formed by a profiled 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 31a, 31b, which have a substantially constant vertical width in their essentially horizontal extension direction, a guide gap for the plastic tube 3 is formed. In order that the plastic tube 3 can slide safely from the receptacle 21 along the laying arm 27 between the holding and guide plates 31a, 31b, guide rollers can be rotatably mounted in the guide gap on the holding and guiding plates 31a, 31b and a guide channel defined through the guide gap form.

At a winding drum-side end 33 of the laying arm 27, a pair of delivery rollers 35 with horizontal axes of rotation are still stored in the guide gap, which ensure guided delivery of the plastic tube 3 from the winding drum end 33 of the laying arm 27 to the winding drum 5.

On an upper side of the winding drum-side end 33, a displacement sensor in the form of a contactor 37 is positioned. 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 I Ia, in which the axis of rotation lies in a guide gap of the laying bar 29. 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 on the winding drum end 33 of the laying arm 27 in both Axially protruding 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.

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 tread of the engagement wheel 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 swing stop ensures that the grip wheel 43 does not press between two already laid winding loops and completely between them by pressing 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. However, the pivot stop stops a lowering of the engagement roller 43 from at most half the thickness 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 from a base plate 55 and a downwardly extending profile carrier 57. 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 return 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 readjusted, for example, when exceeding a deflection threshold of the carriage 53 by the positioning robot 71, which reduces the restoring force of the rear part 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 pneumatic elastic restoring force is generated, which is communicated to the laying arm 27 via the carriage 53 and finally biases the sprocket 43 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 friction deceleration forces in the plastic tube 3, a toothed belt 72 is provided, which is stretched around two pulleys of the eddy current brake 67. 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 positioning robot 71 raises the carrier 23 and its rail 51 in lift direction A substantially no more than the thickness of the plastic tube 3, which is not closer shown vertical pivot stop the laying arm 27 entrains in the vertical lifting direction to raise 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 to 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 of the new The winding surface 15 of the engagement wheel 43 is temporarily raised even further away from the already completed winding layer 15. Only after the first winding loop 17 entrains the engagement wheel 43 in the laying direction V does the engagement wheel 43 descend that its rolling surface comes into rolling contact with the fully-laid winding layer 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 I Ia 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 I Ib takes a (positive) angle α from, 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, while the laying arm 27 is inclined in the opposite axial end position in a (negative) angle of attack α, in particular of the same size, also 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 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.
