Description

Technical area

[0001] The invention relates to a device and a method for winding a thread-like material, in particular an electrical or optical cable or stranded wire. State of the art

[0002] In cable assembly, one sub-step involves the automated and length-independent winding of cut wires or strands, with the transfer of the wire / strand ends at defined positions to a subsequent process step. A strand comprises one (1) electrically or optically conductive core, while a cable can comprise multiple cores.

[0003] The document DE 11 2009 001 415 T5 relates to a device (coiler) for winding a piece of cable or wire into a coil. The device comprises a computer control system, wherein the computer control system includes software that, in operation, varies the diameter of the coil body based on the cable or wire geometry and length, such that the leading end and / or the trailing end are at a specific length and / or position during winding of the cable or wire.

[0004] However, the disadvantage of coil winding using state-of-the-art technology is that the wound wires / strands must be unwound again for installation (e.g., in an automotive wiring harness). Unwinding is often still performed manually, which is a time-consuming process step to say the least. Furthermore, unwinding by hand can result in unacceptably small bending radii and unacceptable torsions, or twisting of the wire / strand. These unacceptably small bending radii and / or unacceptable torsions pose a risk of damage to the wire / strand. Finally, the defined position of the wire / strand ends cannot be ensured for further processing in all state-of-the-art wire / strand winding systems. Description of the invention

[0005] It is therefore an object of the present invention to provide a device and a method in which the unwinding of cables / strands is facilitated and accelerated, and in addition the risk of damage to cables / strands during unwinding is at least reduced.

[0006] The above-mentioned object is achieved by a device for winding a thread-like material according to claim 1 and a method for winding a thread-like material according to claim 11. Further advantageous embodiments of the invention can be found in the dependent claims, the description, and the drawings.

[0007] In particular, the above-mentioned object is achieved by a device for winding a thread-like material, comprising a feed and a separate discharge for guiding the thread-like material, a rotary table arranged between the feed and the discharge, wherein the thread-like material, which can be guided through the feed and the discharge, can pass the rotary table, preferably centrally, and makes the rotary table divisible into a first and a second region, and at least one first winding guide arranged in the first region of the rotary table, and at least one second winding guide arranged in the second region of the rotary table, wherein the at least one first and the at least one second winding guide are fastened to the rotary table,and wherein the thread-like material can wind around the at least one first and the at least one second winding guide during rotation of the turntable and can form a coil wound from the inside out.,

[0008] This device winds a coil from the center outwards. This type of winding contrasts with the prior art, in which a coil is regularly wound around a fixed inner circle, starting from a free end. The center refers to a longitudinal point on the thread-like material or the cable / strand, which is essentially in the center of the cable / strand. Deviations from the exact center of the cable / strand can occur due to the orientation and / or the shape of the coil winding. By winding from the inside outwards, a coil can be wound very compactly with this device, which saves space. At the same time, the device ensures that required (minimum) bending radii are met. This prevents unintentional damage or kinking of the cable / strand.The internally wound coil offers the further advantage that it can be easily unwound by pulling on one or both free ends of the cable / strand. Knotting or unwanted twisting of the cable / strand during unwinding is impossible. The device can wind regardless of the length. The device is particularly suitable for winding cables / strands with a greater length, i.e., more than 0.5 m, preferably more than 2 m, and even more preferably more than 5 m, different cable / strand types, and / or cables / strands with smaller bending radii, particularly in the range of 1 mm or a multiple thereof.

[0009] Preferably, the at least one first and at least one second winding guides have bending radii, at least on their outward-facing surfaces, that correspond at least to the required minimum bending radii. The shape of the winding guides can influence the bending radii or ensure that (minimum) bending radii are maintained. To adapt the shape of the winding guides, the winding guides are preferably mounted on the turntable in an interchangeable manner.

[0010] Preferably, the at least one first and at least one second winding guide from the first and second regions form an S-shape or two separate, spaced-apart shapes. The S-shape enables winding of the coil in a helical shape. Two separately spaced-apart shapes, such as cylinders, enable winding in an O-shape or, if an appropriate force is applied at opposite points on the coil, in a figure-8 shape. The shapes can be adapted to the further processing of the coil, which facilitates the processing.

[0011] Preferably, the turntable has at least one initial guide configured to guide the thread-like material from the feed via the turntable to the discharge. The initial guide enables precise guidance of the cable / strand from the feed to the discharge. The initial guide allows the cable / strand to be wound to be guided at high speed without the cable / strand exhibiting or experiencing misalignment. A higher speed for the cable / strand guidance increases the process speed.

[0012] Preferably, the at least one initial guide can be guided into a winding plane of the turntable or out of the winding plane of the turntable. By guiding the initial guide into the winding plane, a cable / strand that is arranged in the winding plane for winding can be guided. By guiding the initial guide out of the winding plane, it is ensured that the initial guide has no influence on the winding process. The shape of the winding is carried out and achieved independently of the initial guide. The independence from the initial guide simplifies the structure of the device. The shape of the winding is achieved in particular only via the at least one first and the at least one second winding guide.

[0013] Preferably, the feed has at least one first feed and / or the discharge has at least one second feed for moving the thread-like material, and in particular for fixing and / or transferring at least one free end of the thread-like material at a defined position to a subsequent process. The feed or feeds enable the cable / strand to be made available to the device. Furthermore, at least one feed holds a free end of the cable / strand in a defined position. With the aid of a feed, at least one free end can also be readjusted to achieve a specific position or orientation.

[0014] Preferably, the at least one first and / or the at least one second feed comprises a length measurement. The length measurement on a feed enables precise alignment of a cable.

[0015] Preferably, the at least one second feed at the discharge is movable, preferably along a circular path, in the direction of the at least one first feed at the feed. The movement of the second feed enables the flexible alignment of the corresponding free end of the cable / strand. In particular, the movable feed allows both free ends of a wound cable / strand to be arranged on one side of the coil, in particular parallel to each other.

[0016] The turntable preferably has at least one tension meter or torque monitor (e.g., on the turntable drive). The tension meter or torque monitor is suitable for detecting the tension on the cable / strand being wound. If the tension exceeds a critical value, winding can be stopped. By monitoring and, if necessary, stopping the winding process, damage to the cable / strand being wound can be prevented.

[0017] Preferably, a distance between the at least one first and the at least one second winding guide can be variably adjusted. By varying the distance, the final rotational position or orientation and / or the shape of the coil can be influenced, particularly in the case of an 8-shape coil, in order to standardize transfer or removal to a subsequent process. In particular, the distance can be (automatically) reduced when a force is applied to the coil to form an 8-shape. The (automatic) reduction of the distance prevents unwanted tensile forces on the cable / strand when forming the 8-shape. Preferably, a distance is automatically adjusted via an interface to a cutting or cutting system and / or a system management system (such as SAP), depending on parameters of the cable / strand, such as the supplied cable / strand length and the cable / strand type.

[0018] The above-mentioned problems are further solved in particular by a method for winding a thread-like material, wherein the method comprises at least the following steps: guiding the thread-like material from a feed to a separate discharge, wherein the thread-like material extends, preferably centrally, over a rotary table arranged between the feed and discharge, until a predetermined length point of the thread-like material has reached a predetermined point, in particular the center of the rotary table, and rotating the rotary table in a predetermined direction of rotation, wherein the thread-like material winds around at least one first and at least one separate second winding guide which are fastened to the rotary table, until the thread-like material is wound from the inside out into a coil.

[0019] Using this process, a thread-like material can be wound compactly without exceeding predetermined bending radii. To unwind the coil, simply pull on one or both free ends, and the coil unwinds without knotting or unwanted torsion. The process is simple and robust to implement.

[0020] Preferably, the method further comprises the step of: prior to rotating the turntable, leading an initial guide out of a winding plane of the turntable. In particular, prior to the step of guiding the thread-like material from a feed to a separate discharge, an initial guide is led into the winding plane of the turntable. The inward and outward guidance of the initial guide makes it possible to provide guidance across the turntable, wherein the guide, when led out of the winding plane of the turntable, does not impair the winding of the thread-like material around the first and second winding guides. The initial winding guide is irrelevant to the coil winding process.

[0021] Preferably, the turntable rotates in a constant winding plane, or the winding plane develops along a third axis. If the turntable rotates in a constant winding plane, a flat coil is produced. If the winding plane is changed during winding, a multi-layer coil is produced.

[0022] The method preferably further comprises the step of stopping the rotation of the turntable when a free end is detected at a limit switch, which is preferably arranged between the feed and at least one first feed and / or between at least one second feed and the discharge, and in particular correcting the position of the free ends with the aid of the at least one first and / or the at least one second feed if deviations occur. Stopping the rotation of the turntable when (at least) one free end is detected at a limit switch has the advantage that both free ends are still held by the first or second feed at this time and thus have defined positions. If these defined positions are to be changed or adjusted, this can be done with the aid of the first or second feed.

[0023] Preferably, the method further comprises the step of, in particular automatically, removing the coil wound from the inside, which has defined positions of the free ends, from the turntable, and preferably from the turntable and the at least one feed. The wound coil with defined positions of the free ends can be fed to further process steps, such as tying or finishing the free ends, with a defined size and the defined positions of the free ends.

[0024] Preferably, the method further comprises the step of joining at least two points of an O-shaped coil to form an 8-shaped coil. An 8-shaped coil has the advantage that the coil can be gripped clearly at one point, for example, automatically by a gripper.

[0025] Preferably, the method further comprises the step of automatically adjusting the predetermined length point, a distance between the at least one first and the at least one second winding guide, and / or the positions of the free ends using an interface to a cutting system or a system management system. The automatic adjustment of said parameters simplifies and enables optimal winding of the thread-like material.

[0026] The following description of embodiments is made with reference to the accompanying figures. In this figure: Fig. 1 is a plan view of a first embodiment of an apparatus for winding a thread-like material; Fig. 2 is a plan view of an embodiment of a wound coil of the thread-like material which can be wound with the device of Fig. 1 was wrapped; Fig. 3 is a plan view of a second embodiment of the device for winding a thread-like material; Fig. 4 the view from Fig. 3 with a partially wound filamentary material; Fig. 5 is a plan view of a first embodiment of a wound coil of the thread-like material which can be wound with the device of Fig. 3 and Fig. 4 was wrapped; Fig. 6 is a plan view of a second embodiment of a wound coil of the thread-like material which is wound with the device of Fig. 3 and Fig. 4 was wrapped; Fig. 7 is a plan view of a third embodiment of the device for winding a thread-like material; and Fig. 8 the view from Fig. 7 with a partially wound thread-like material.

[0027] In the following, preferred embodiments are described in detail with reference to the accompanying figures.

[0028] Fig. 1 shows an embodiment of a device 1 for winding a thread-like material 2, such as an electrical or optical cable / strand. The device 1 has at least one inlet and one separate outlet 4, 5 for guiding the thread-like material 2. The inlet and outlet 4, 5 are preferably arranged opposite one another so that a cable / strand 2 can be guided linearly from the inlet 4 to the outlet 5. In the embodiment shown, the inlet and outlet 4, 5 are designed as guide tubes. In alternative embodiments, other types of guidance, e.g., recesses, are possible. Preferably, the cable / strand 2 to be wound is already cut to length at the inlet 4. In an alternative embodiment, a cable / strand 2 to be wound can also be cut to length after being guided through the inlet and outlet 4, 5.

[0029] For moving a thread-like material 2 or the cable / strand, the feed 4 has at least one first feed 6 and / or the discharge 5 has at least one second feed 7. A feed 6, 7 preferably has at least one frequency-controlled belt drive. In particular, a feed 6, 7 also serves to fix the cable / strand 2, for example by means of two oppositely arranged belt drives. Preferably, at least one feed 6, 7 comprises a length measurement. This makes it possible to determine exactly when a length point L1, L2, L3 on the cable / strand 2 is preferably arranged on the center point M of the turntable 10. Furthermore, the at least one second feed 7 on the discharge 5 is preferably movable, preferably along a circular path K, in the direction of the at least one first feed 6 on the feed 4. Due to the mobility, both free ends 3 of a wound cable / strand 2 can be arranged on the same side of the coil 9, 109b.In particular, both free ends 3 can be arranged at a first position P1 (cf. . Fig. 2 and Fig. 6).

[0030] The device 1 further comprises a turntable 10, which is arranged between the inlet and outlet 4, 5. The arrangement of the turntable 10 between the inlet and outlet 4, 5 can also comprise a non-linear alignment of the inlet and outlet 4, 5, i.e. the inlet and outlet can also be arranged at an angle to one another, for example at a 90-degree angle. The turntable 10 is rotatable about its central axis, which runs along a third direction Z through its center point M. The direction of rotation D and the rotation speed are adjustable. In a preferred embodiment, the center point M of the turntable 10 is arranged on a line between the inlet and outlet 4, 5 (cf. Fig. 8). This arrangement allows the thread-like material 2 or the cable / strand, which is guided through the inlet and outlet 4, 5, to pass centrally through the turntable 10. The central alignment of the cable / strand 2 to be wound on a winder (turntable 10) is contrary to the known prior art. By centrally aligning the cable / strand 2, winding from the center is possible. The central alignment of the cable / strand 2 makes the turntable 10 divisible into a first and a second area B1, B2 (see Fig. 1). Furthermore, in one embodiment, the turntable 10 comprises at least one tension meter or torque monitor, so that the tension on a cable / stranded wire 2 to be wound can be monitored. Furthermore, the turntable 10 can comprise a cover, for example, to ensure a flat winding of the cable / stranded wire 2.

[0031] The illustrated device 1 further comprises at least one first winding guide 11, which is arranged in the first region B1 of the turntable 10, and at least one second winding guide 12, which is arranged in the second region B2 of the turntable 10. This information is based on a basic position of the turntable 10, as shown in Fig. 1, Fig. 3 or Fig. 7. In this basic position, in the illustrated first and second embodiments (see Fig. 1 and Fig. 3) the turntable 10 is symmetrical to a central axis on which a cable / strand 2 to be wound can be arranged. The at least one first and at least one second winding guide 11, 12 are fastened to the turntable 10, in particular detachably. In alternative embodiments, the first and second winding guides 11, 12 can have shapes other than those shown here. Due to the arrangement of the at least one first and at least one second winding guide 11, 12, the thread-like material or the cable / strand 2 can wind around the at least one first and at least one second winding guide 11, 12 when the turntable 10 rotates, and form a coil 9 wound from the inside out (see Fig. 2).

[0032] The at least one first and at least one second winding guide 11, 12 have bending radii R1, R2, at least on their outwardly directed surfaces, which correspond to at least the required minimum bending radii. The outwardly directed surfaces relate to the center point M of the turntable 10 and describe surfaces facing away from the center point M. Preferably, all surfaces of the at least one first and second winding guide 11, 12 have bending radii R1, R2 that are greater than or equal to the required minimum bending radii or are at least partially unbent, so that a cable / strand 2 to be wound complies with the required minimum bending radii. The minimum bending radii are predetermined. The bending radii R1, R2 on the at least one first and second winding guide 11, 12, in particular at comparable locations on the first and second winding guide 11, 12, can be identical or different (cf. Fig. 1, Fig. 3 and Fig. 7).

[0033] Furthermore, the arrangement of the at least one first and the at least one second winding guide 11, 12 from the first and the second area B1, B2 can result in an S-shape, as shown in Fig. 1. A coil 9 wound with this arrangement then has a circular helical shape with an S-shape of the cable / strand 2 in the center of the coil 9 (see Fig. 2). In the second and third embodiments of the device 100, 200 shown in the Fig. 3-8, the at least one first and second winding guide 111, 112, 211, 212 form two separate, spaced-apart shapes on the turntable 110, 210. The shapes can be identical or different. The spaced-apart winding guides 111, 112, 211, 212 lead to at least partially larger inner diameters of the wound coils 109a, 109b (cf. Fig. 5, Fig. 6 and Fig. 8). In all embodiments shown, a distance A between the at least one first and the at least one second winding guide 11, 12, 111, 112, 211, 212 can be variably adjusted.

[0034] Furthermore, the Fig. The device 1 shown in Figure 1 has at least one initial guide 13 on the turntable 10. The initial guide 13 is designed to guide the thread-like material 2 from the feed 4 via the turntable 10 to the discharge 5. The initial guide 13 is only used before the turntable 10 rotates or the coil 9 is wound. During the rotation of the turntable 10, the initial guide 13 would otherwise influence the shape of the winding or the coil 9. To prevent this influence, the at least one initial guide 13 can be guided into a winding plane XY of the turntable 10 or out of the winding plane XY of the turntable 10. In one embodiment, the initial guide 13 can be sunk into the turntable 10 for the inward or outward guidance. In an alternative embodiment, the initial guide 13 can be moved from the winding plane XY along the third direction Z, e.g. lifted away from the turntable 10.

[0035] The following describes an embodiment of a method for winding a thread-like material 2, in particular with reference to the first embodiment of the device 1, wherein the method comprises at least the following steps: guiding the thread-like material 2 from the feed 4 to the separate discharge 5, wherein the thread-like material 2 extends, preferably centrally, over the turntable 10, which is arranged between the feed and discharge 4, 5, until a predetermined length point L1, L2, L3 of the thread-like material 2 has reached a predetermined point, in particular the center point M, of the turntable 10. The thread-like material 2 or the cable / strand is preferably already cut to length. In the embodiment shown, the guiding is carried out by the frequency-controlled belt drives 6, 7 pushing the cable / strand 2 over the turntable 10 from the feed to the discharge 4, 5.For guiding over or through the turntable 10, the initial guides 13 and an optional cover on the turntable 10 can form a type of guide tunnel. The positioning of the cable / stranded wire 2, in particular the predetermined length points L1, L2, L3, on the turntable 10, as well as the arrangement of the winding guides 11, 12 on the turntable influence the subsequent position of the free ends 3 of the cable / stranded wire 2. After positioning the cable / stranded wire 2 on the turntable 10, the "guide tunnel" is removed. In the illustrated embodiment, for this purpose, before rotating the turntable 10, the initial guide 13 is led out of a winding plane XY of the turntable 10. The winding plane XY can in particular comprise a constant winding plane XY or a winding plane XY developing along the third axis Z.With a constant winding plane XY, the result is a flat coil 9, whereas with a three-dimensional winding plane, the result is a multi-layer coil. For example, to develop the winding plane XY in the third direction Z, the turntable 10 can be moved along the third direction Z during the rotation or winding of the cable / strand 2.

[0036] Subsequently, the turntable 10 is rotated in a predetermined direction of rotation D, whereby the thread-like material 2 is wound around at least one first and at least one separate second winding guide 11, 12, which are fastened to the turntable 10, until the thread-like material 2 is wound from the inside out into a coil 9. Depending on the dimensions of the cable / strand 2, the predetermined length point L1 and the winding guides 11, 12, the free ends 3 on the wound coil 9 arrive at the same position as in Fig. 2, or at a first position P1 and a second position P2 (cf. Fig. 5). The winding guides 11, 12 on the turntable 10 are shaped so that the minimum bending radii of the cable / stranded wire 2 to be wound are always maintained. Furthermore, the winding guides 11, 12, which rotate with the turntable 10, together with the frequency-controlled belt drives and the at least one tension meter or the at least one torque monitor, wind the cable / stranded wire 2 into the desired shape and keep it taut.

[0037] During winding, flat winding is possible, especially if a second, synchronously rotating turntable (or cover) is arranged above the turntable 10 with the winding guides 11, 12 at a distance slightly greater than the cable / strand diameter. Furthermore, winding as a bundle is also possible if the winding guides 11, 12 on the turntable are designed accordingly for multi-layer winding. Possible winding shapes include flat or multi-layer helical shapes, flat or multi-layer O-shapes, and / or flat or multi-layer 8-shapes, wherein the 8-shapes are formed by central clamping or application of a force F at the Fig. 5 and Fig. 6. Combinations of the winding forms mentioned are also possible.

[0038] At the end of the turning or winding process, the rotation of the turntable 10 can be stopped if a free end 3 is detected at a limit switch 8, which is preferably arranged between the feed 4 and at least one first feed 6 and / or between at least one second feed 7 and the discharge 5. This enables automated process control. The at least one limit switch 8 is preferably arranged outside the respective belt drive 6, 7. In particular, the at least one limit switch 8 detects an approaching free end 3 of the cable / stranded wire 2 and stops the rotation of the turntable 10 so that the two free ends of the cable / stranded wire 2 come to rest at a defined point. Due to the arrangement of the at least one limit switch 8, the free ends 3 of the cable / stranded wire 2 can still be held in the corresponding feed 6, 7 when the rotation is stopped.By holding the free ends 3, in particular an (automatic) correction of the position of the free ends 3 is possible with the aid of the at least one first and / or the at least one second feed 6, 7 if deviations occur. Each feed 6, 7 can in principle move a cable / strand 2 in both directions along the first direction + / - X, i.e. back and forth. Furthermore, in the embodiment shown, the second feed 7 can be moved in the direction of the first feed 6, in particular along the circular path K, in order to arrange the two free ends 3 of the cable / strand 2 on a common side of the coil 9. Likewise, a final rotational position of the turntable 10 and thus also the final rotational position of the wound coil 9 can be set via the optionally adjustable distance A between the winding guides 11, 12.After a coil 9 has been wound and the first position P1 or the first and second positions P2 of the free ends 3 have been determined, the coil 9 wound from the inside, which has a defined position of the free ends 3, can be removed from the turntable 10, preferably from the turntable 10 and the at least one feed 6, 7. The removal can be done manually or automatically, in particular with a gripper. The coil 9 can then be tied off and / or further processed. The winding guides 11, 12 can be controlled or positioned on the turntable 10 in such a way that the coil 9 can be removed without damage.

[0039] The described method is identical for the second and third embodiments of the device 100, 200 shown. Differences arise primarily in the predetermined length point L2, L3 to which a cable / strand 2 to be wound is guided to a predetermined point, in particular the center point M, of the turntable 10. In general, it can be said that depending on the desired winding shape, cable / strand length, desired position of the free ends 3 of the cable / strand 2, etc., different starting positions, i.e., length points L1, L2, L3 or deviations from the exact length center, result for the winding from the cable / strand center or from the inside out.
