Description

Devices for winding a cable and corresponding

Procedure to do so

The invention relates to devices for winding up a cable and methods for winding up a cable according to the independent claims.

A cable is processed industrially in a cable processing machine. The cable is typically unwound from an endless reel and conveyed to different cable processing stations. The different cable processing stations, such as a cutting device for cutting the cable to a predefined length, a winding device for winding the cut cable into a cable reel and others, are used for industrial processing of the cable. Winding the cable into a cable reel is an essential process step in the cable processing process, so that a cable reel can be easily transported.

EP 1 423 325 A1 discloses a winder for winding a cable to be wound, with a winding body on which a predetermined length of the cable is wound. After the roll has been created, it is removed from the roll body and transferred to a subsequent position for further processing or storage.

US Pat. No. 6,669,129 B discloses a winding device with a disk-shaped winding plate for winding glass fiber cables into a winding. Furthermore, there is a cam disk, the winding plate and the cam disk being rotatable relative to one another. The winding plate has several carrier elements for adjusting the winding diameter, which for this purpose can be moved along a guide radially towards the edge of the winding plate. The cam has several track-shaped grooves in which the carrier elements engage. Turning the cam causes the carrier element on the winding disc to be shifted so that the winding diameter can be adjusted. The winding plate and the cam can be coupled using a screw. The disadvantage of the known solution is that there is a screw that rotates with the cam disc for coupling the winding plate and the cam disc, which screw is manually operated by a user. A reproducible coupling of the cam disk with the winding plate is not possible.

EP 3 142 953 A1 discloses a device for winding a cable into a reel with a rotatable winding plate which has several winding fingers. A holding element for arranging a leading cable end is arranged on the winding plate.

The disadvantage of this known solution is that the leading end of the cable is transferred to a holding unit of a transfer unit before the reel is finished, before the reel is completely wound and the trailing cable end is released in an uncontrolled manner after the cutting process.

It is the object of the present invention to remedy one or more disadvantages of the prior art. In particular, a device for winding a cable into a reel is to be created in order to improve the handling with, as well as the stability, of the wound reel in a cable processing device. Furthermore, a method for winding a cable into a reel is to be created, which improves the handling with, as well as the stability, of the wound reel in a cable processing device.

This object is achieved by the devices and methods defined in the independent claims. Advantageous further developments are set out in the figures, the description and in particular in the dependent claims.

A device according to the invention for winding a cable into a spool, wherein the spool comprises at least one turn and comprises a leading cable end and a trailing cable end, has a winding plate on which several winding fingers are movably arranged, and has at least one fixing unit for fixing the leading Cable end, wherein the at least one fixing unit is arranged on the winding plate, and has a drive device for driving the winding plate. A first holding unit is arranged on a first winding finger, wherein the cable can be held with the first holding unit in the region of the trailing cable end.

Typically, before the winding of the cable is finished, the rotating winding plate is briefly stopped in order to cut off the trailing cable end. The winding plate is then set in rotation again in order to complete the winding up of the cable. The length of the trailing cable end is defined by the length from the cutting edge of the leading cable end to the first holding unit. The arrangement of the trailing cable end in the first holding unit prevents the trailing cable end from slipping if the winding plate continues to rotate after the trailing cable end has been cut.

Slipping would change the length of the trailing cable end unpredictably. At the same time, the device can be used to set the distance between the cut trailing cable end and the first holding unit in such a way that the length of the trailing cable end in the wound coil can be defined. Knowing the length of the trailing cable end of a coil is relevant for the further handling of the wound coil in a cable processing machine. For example, an electrical plug connection is attached to the cable end, the wound coil being transported to a crimping press and at least the trailing cable end being fed to the crimping press. The additional holding of the cable with the first holding unit stabilizes the reel after the cable has been wound up, since the trailing cable end is prevented from slipping in the reel after it has been wound up. A further fixation of the trailing cable end can be dispensed with, so that the process cycle time of the process step for winding is shortened.

The cable can be an electrical or optical cable, which has at least one conductor, or one or more conductor strands, with cable insulation includes. The device described here can also be used to wind up other pliable materials, such as a hose or a rope. The device can thus be used universally for different pliable materials.

A second holding unit is preferably arranged on a second winding finger, the cable being able to be held in the second holding unit in the region of the leading end of the cable. The additional holding of the cable in the wound bobbin with the second holding unit stabilizes the wound bobbin and prevents the wound bobbin from slipping or falling apart. This enables the first fixing unit to be opened even before the coiled cable is processed further, when the coiled cable is then gripped, for example, by a transfer gripper. The process cycle time of the

Process step shortened during transport. The length of the leading

Cable end is defined by the length from the end of the leading one

Cable end up to the second holding unit when the reel is on the winding plate. The knowledge of the length of the leading cable end of a coil is necessary for the further handling of the wound coil in one

Cable processing machine relevant, since the cable ends of the cable are typically further processed in further processing steps. With the device described above, the distance between the first fixing unit and the first holding unit can be selected in such a way as to define the length of the trailing cable end in the wound coil.

The distance between the several winding fingers on the winding plate is advantageously adjustable for setting the bobbin diameter. The distance between the several winding fingers affects not only the coil diameter, but also at least the length of the leading cable end.

The first holding unit is preferably arranged to be movable along the first winding finger. The first winding finger has a winding area which extends from a free end of the first winding finger to first holding unit extends. Moving the first holding unit along the first winding finger to a selectable area on the first winding finger allows the winding area to be defined and can be set individually for each cable type. Depending on the cable type, the properties, such as the coil height or the coil thickness (depending on the number of turns of the coil) of the wound coil can thus be adapted or preset.

Alternatively or in addition, the second holding unit is arranged to be movable along the second winding finger. The second winding finger has a winding area which extends from a first end of the second winding finger to the second holding unit. Moving the second holding unit along the second winding finger to a selectable area on the second winding finger also allows the definition of the winding area, but at a further point on the winding plate and can be set individually for each cable type, as described above.

At least one of the holding units is preferably designed as a passively clamping cable clamp. A cable clamp is a fixing device for fixing the cable, the cable being held in a passive clamping manner in the state in which it is arranged in the cable clamp. In this way, the cable can be held easily and without motorized components, at least temporarily, during and after winding on the winding plate.

A winding finger advantageously has several holding units, so that each turn N of the cable is held in its own holding unit. The wound cable can thus be wound in a space-saving and structured manner.

The fixing device advantageously comprises a first gripper jaw and a second gripper jaw, between which the cable can be fixed at least temporarily. The two gripper jaws are arranged on the respective winding finger. These can be transferred from an open state to a closed state, it being possible for the transfer to take place with the aid of the cable which is fixed between the two gripper jaws. In particular, at least the first gripper jaw can be moved with the aid of a spring system arranged on the respective holding unit so that it can be transferred independently at least from the open state to the closed state. This provides a simple and efficient mechanism for a cable clamp. The first winding finger with the first holding unit and the second winding finger with the second holding unit are preferably arranged opposite one another on the winding plate. The two cable ends can be held on the winding plate in such a way that the leading cable end and the trailing cable end have the same length and the two cable ends, at opposite points on the wound coil, can tangentially leave the wound coil. A readjustment of the cable ends in the further cable processing process can be dispensed with.

Further winding fingers are preferably arranged on the winding plate, the further winding fingers each having at least one support element for supporting the wound coil. A compact coil with an approximately circular bobbin can thus be wound, the winding plate for this being able to be of circular design and having one of the winding fingers at least every 60 °. The support elements support the cable in such a way that the turns of the coil are held together at least in sections and enable the individual turns of the wound coil to be arranged in a row.

The plurality of winding fingers are preferably arranged with a constant arc length to one another on the winding plate, so that an approximately circular and thus stably wound coil can be generated. Further fixing units are preferably arranged on the winding plate, so that at least the length of the leading cable end can be set individually for the respective cable type. The further fixing units are constructed structurally and functionally like the at least first fixing unit. The further fixing units are preferably arranged offset to the winding fingers with at least one holding unit, so that at least the length of the leading cable end of the coil is predetermined.

At least the first fixing unit preferably has gripping elements which can be transferred from a fixing position into a release position. In this way, at least the leading end of the cable can easily be fixed on the winding plate. The gripping elements hold the leading end of the cable stable when the cable is being wound into a reel, so that the leading end of the cable can be prevented from slipping.

The gripping elements can advantageously be transferred from the fixing position to the release position by a motor, the transfer taking place continuously. For this purpose, the device has a transfer device which has a drive unit, such as a pneumatic cylinder, and a transfer unit, such as a transfer ram. A transfer ram exerts a force on the respective gripping element in order to transfer it.

The gripping elements are advantageously connected to a spring element, the transfer device being able to be brought into operative connection with the spring elements in order to transfer the gripping elements from the fixing position into the release position. This makes it possible to physically separate the gripping elements from the drive unit when they are in the fixing position.

Alternatively or in addition, at least the first fixing unit has an adhesive section for at least temporarily fixing the leading cable end. This means that at least the leading end of the cable can easily be guided on the winding plate. An adhesive coating, for example an adhesive coating, which temporarily fixes the leading cable end, can be arranged on the adhesive section.

The transfer device is advantageously separated from the winding plate and arranged in a stationary manner on the device. As a result, the winding plate has a lower mass, which is set in rotation during winding, so that the Winding plate is easier and more compact to manufacture. Complex rotary feedthroughs for supplying energy to the transfer device can be dispensed with.

Further transfer devices are advantageously provided which are each assigned to the further fixing units on the winding plate. The further transfer devices are constructed structurally and functionally like the transfer device described above. The winding plate can be moved into a basic position or a predefined rest position, so that the respective transfer device is assigned to a specific fixing unit.

A movable cam disk is preferably provided, with which the distance between the several winding fingers can be adjusted, the cam having at least one groove with which the several winding fingers can be brought into operative connection to adjust the distance between the several winding fingers. At least two of the winding fingers can be moved on the winding plate, preferably linearly and in the radial direction on the cam disk. The cam can be rotatable. Rotating the cam disc transmits forces to the winding fingers via a contact surface guided in the at least one groove, so that they can be moved radially in the direction of the winding disc edge. This means that the coil diameter is continuously adjustable.

The groove is advantageously arranged in a spiral shape in the cam, the groove having a very flat angle of inclination, which is preferably flatter than the arctangent of the coefficient of friction, which results from the material pairing cam / winding finger and the contact surface. This contact surface is formed between the cam disk and the plurality of winding fingers. This ensures that the rotary movement can still be converted into the desired linear radial movement when the distance between the multiple winding fingers is set. In addition, such a groove ensures that the forces acting radially on the plurality of winding fingers during the winding up of the cable cannot lead to a movement of the plurality of winding fingers and thus to an undesired adjustment of the diameter. this is possible due to the high static friction and the high transmission ratio in the spiral groove. This means that there is no need for an additional, co-rotating braking device. The at least one spiral groove can be designed as an Archimedean spiral. In this way, the diameter adjustment of the winding fingers can be carried out linearly to the angle of rotation of the cam disk in order to precisely adjust the multiple winding fingers to one another. As an alternative or in addition, there is a slip clutch, which additionally increases the friction between the cam disk and the winding plate described above.

The cam disk preferably has a plurality of grooves with which the plurality of winding fingers can be brought into operative connection in order to set the distance between the plurality of winding fingers. In this case, for example, a winding finger is arranged in the first groove and a further winding finger is arranged in the further groove, which can be moved independently of one another in the respective groove. The first groove and / or the further groove can be designed as described above.

The cam is preferably arranged on a drive shaft of the drive device in order to drive the cam with the drive device. As a result, the cam disc can be driven directly and the process of setting the reel diameter is simplified, the present device only requiring a common drive device with a drive motor for driving the winding disc and for driving the cam disc. The same drive device sets the distance between the several wrapping fingers and moves the wrapping plate. A single drive device can thus be used for rotating the winding plate and for setting the spacing of the reel diameter.

Alternatively or in addition, the winding plate is arranged on a drive shaft of the drive device in order to drive the winding plate. As a result, the winding plate can be driven directly, only a common drive device with a drive motor being required. The same drive device sets the distance between the several wrapping fingers and moves the winding plate. A single drive device can thus be used for rotating the winding plate and for setting the spacing of the reel diameter.

Alternatively or in addition, a drive device can be provided for driving the winding plate and a further drive device can be provided for driving the cam disk. In this way, the two components can be driven separately and independently and, for example, while the winding plate is rotating, the setting of the distance of the coil diameter can be set at the same time, so that the process can be accelerated.

Preferably, there is at least one pusher device with which the winding plate can be locked, wherein the pusher device can be transferred at least from an inactive position to an active position. If the ram device is in an active position, the winding plate is locked and thus positioned in a rotationally fixed manner. The at least one ram device is advantageously arranged in a stationary manner on the device so that it does not rotate with the winding plate.

The winding plate can preferably be locked and at the same time decoupled from the cam disk. The ram device locks the winding plate in the active position, with the cam disc being rotatable independently. There is no need for a separate, co-rotating drive for the winding disc. The mass of the winding plate is thus reduced and a rotary feedthrough for supplying energy to a separate drive can be dispensed with, so that it has a simple and compact design.

The plunger device can advantageously be transferred at least from the active position to the inactive position in order to couple the winding plate and the cam disk. If the ram device is in the inactive position, the winding plate and the cam are coupled and can be rotated together. In other words, the plunger device is designed in such a way that it not only enables the winding plate to be locked, but also simply enables the coupling / decoupling between the winding plate and the cam, so that the aforementioned advantages are improved. The at least one plunger device advantageously comprises at least one pneumatically driven cylinder for transferring the at least one plunger device from the active position to the inactive position, so that a simple drive for activating or inactivating is provided.

A sensor is advantageously provided with which at least one basic position of the winding plate can be detected. The winding plate can thus be reproducibly positioned in a desired basic position in which the cam disk and the winding plate can be coupled or decoupled or the plunger device can be moved into the active position. The sensor consists, for example, of a non-contact switch with an inductive measuring principle and a matching counterpart. Alternatively, the sensor can be an optical sensor and / or a magnetic sensor and / or a mechanical sensor. For example, the sensor can be designed as a rotary encoder on the drive shaft of the winding plate, which measures a current angle of rotation of the cam disk and / or the winding plate in any position and, in particular, together with the corresponding motor controller of the motor of the drive device, allows a maximum positioning speed. By switching from the motor controller to this rotary encoder when approaching the at least one basic position of the winding plate, it can be rotated a little faster. Undesired relative movements between the winding plate and the cam disc (for example by turning by hand) can be detected at any time and not only in the basic position.

The plunger device advantageously has a locking plunger and the winding plate has a locking receptacle in order to couple the winding plate with the cam disk in a non-positive manner at least in two places. The locking receptacle can comprise a winding plate groove on the winding plate. The locking ram can be moved, for example, with the aid of the pneumatically driven cylinder of the ram device, so that the winding plate can be locked easily. A separate locking of the winding plate can be dispensed with, so that the device is constructed in a space-saving and compact manner. A locking ram is a locking unit that exerts a force on the winding plate and / or exerts the cam and / or a locking receptacle attached to one of these elements in order to lock it.

A coupling device is preferably provided for coupling the winding plate to the cam disk, so that a mechanically stable coupling is possible. In particular, the coupling device is at least on

Winding plate arranged in a stationary manner, as a result of which reliable coupling of the winding plate with the cam disk is ensured during the winding process step.

The plunger device advantageously comprises an actuator plunger for actuating the coupling device, so that the coupling device can be activated when the plunger device is transferred from the inactive position to the active position, and vice versa, can be deactivated. The actuator plunger can be moved with the aid of the pneumatically driven cylinder. A

Actuator plunger is an actuating unit which exerts a force on the coupling device in order to transfer it from one position to another position, preferably by pressing in a spring element over an active surface on a tensioning lever and / or another tensioning element.

The coupling device advantageously comprises a tensioning lever which is arranged on the winding plate. The clamping lever can be arranged on a clamping joint. The tensioning lever can be brought into operative connection with the cam disk at least temporarily via the tensioning lever mounted in the tensioning joint and with the aid of the plunger device, with the force required for this being able to be generated via a tensioning spring element. The clamping lever can thus be actuated so easily with the aid of the pneumatically driven cylinder that the cam disk can be coupled directly and thus a simple and reliable coupling is made possible.

The coupling device preferably comprises at least one belt, so that simple and reliable coupling of the winding plate to the cam disk is possible. In this case, the coupling device is designed to provide a. When the belt tension of the at least one belt changes Establish or loosen a frictional connection between the winding plate and the cam disk.

The coupling device advantageously comprises a tensioning element which is arranged on the winding plate. The actuator plunger of the plunger device can be brought into operative connection at least temporarily with the coupling device. The tensioning element can be arranged on a tensioning lever and on a tensioning joint. The tensioning lever can be brought into operative connection at least temporarily with the belt via the tensioning lever mounted in the tensioning joint and with the aid of the ram device, the force required for this being able to be generated via a tensioning spring element. The tensioning element can thus be actuated so easily with the aid of the pneumatically driven cylinder that the tensioning element relaxes the at least one belt at least in part, so that there is no frictional connection between the cam disk and the at least one belt. The at least one belt is arranged in a stationary manner on the winding plate. In this way, the cam disk can be rotated with the aid of the drive device and is at the same time decoupled from the winding plate. If the actuation unit is deactivated, the at least one belt is automatically tensioned again with the aid of the tensioning element, so that there is a frictional connection between the cam disk and the at least one belt. The cam disk and the winding plate are thus coupled.

A further plunger device is advantageously present with which the winding plate can be coupled to the cam disk, the further plunger device being able to be transferred at least from an active position to an inactive position. The further tappet device can be constructed structurally identically to the at least one tappet device described above and comprise its functional features and structural components and in particular has a further coupling device as described above with a further belt. The winding plate and the cam disks are thus coupled to one another at at least two positions on the device, so that increased process reliability is ensured when rotating the winding plate and when winding the cable. The further tappet device is advantageously arranged at a distance from the at least one tappet device and, in particular, the two tappet devices are arranged opposite one another on the device. In this way, the winding plate and the cam disk can be coupled to one another symmetrically in at least two positions.

A method according to the invention for winding a cable into a reel with a device comprising a winding plate with several winding fingers, in particular with a device as described here, comprises at least the following steps:

- Feeding a leading end of a cable to the winding plate;

- Fixing the leading end of the cable to a fixing unit on the winding plate;

- Winding up the cable to form a reel with several turns, the winding plate being driven by a drive device;

- Insertion of the cable in the area of the trailing cable end in a first holding unit on a first winding finger.

With the method described above, the distance between the first fixing unit and the first holding unit can be adjusted in such a way as to define the length of the trailing cable end in the wound coil. Typically, before the winding of the cable is finished, the rotating winding plate is briefly stopped in order to cut off the trailing cable end. The winding plate is then set in rotation again in order to complete the winding up of the cable. The arrangement of the trailing cable end in the first holding unit prevents the trailing cable end from slipping if the winding plate continues to rotate after the trailing cable end has been cut. Slipping would change the length of the trailing cable end unpredictably. At the same time, this can reduce the distance between the cut trailing cable end and the first holding unit can be set in such a way that the length of the trailing cable end in the wound coil can be defined. The knowledge of the length of the trailing cable end of a coil is relevant for the further handling of the wound coil in a cable processing machine, as already described above.

Preferably, after the cable has been wound into a coil with several turns, the leading end of the cable is held on a second winding finger with a second holding unit. The additional holding of the cable in the wound bobbin with the second holding unit stabilizes the wound bobbin and prevents the wound bobbin from slipping or falling apart.

Preferably, before the leading end of the cable is fed to the winding plate

the winding plate is rotated into a basic position, the basic position preferably being detected with a sensor;

- The winding plate is decoupled from a cam disk with the aid of a ram device and locked at the same time;

- At least the distance between the first winding finger and the second winding finger for setting the coil diameter is set with the cam disc;

When the winding plate is locked and decoupled, the distance between the winding fingers can be easily adjusted using the cam.

Another device according to the invention for winding a cable into a spool comprises a winding plate on which several winding fingers are movably arranged, a cam disk with which the distance between the several winding fingers can be adjusted, with a drive device for driving the movable cam disk or for driving the winding plate is available. Furthermore, there is at least one ram device with which the winding plate or the Cam disk are lockable, the at least one tappet device can be activated.

There is no need for a further drive for the cam disk or for the winding plate, for example rotating at the same time. This reduces the mass of the winding plate and a rotary feedthrough for supplying energy to a separate drive can be dispensed with, so that it is of simple and compact design. This device can have essentially the same functional and structural features as the device described above.

The plunger device is preferably arranged in a stationary manner on the device. This means that further rotating components can be dispensed with, so that the mass of the winding plate, for example, is reduced. The ram device is designed as described here.

The at least one plunger device can preferably be transferred from an active position to an inactive position. The at least one plunger device is designed as described here. Furthermore, a further ram device can be present, as described here in the present case. A holding unit, as described above, is not absolutely necessary, but can optionally be arranged on at least one of the plurality of winding fingers.

The plunger device preferably has a movable locking plunger which can be brought into operative connection with a locking receptacle on the cam disk and / or on the winding plate. In this way, the winding plate or the cam disk can be locked in a safe position. A complex coupling device, as described above, can be dispensed with. For example, the locking receptacle is a locking opening or a locking groove, or a locking tooth or a locking slot in which the locking plunger penetrates at least in sections in order to lock the cam disc and / or the winding plate. Here, several such active compounds can be in the form of the locking receptacle over the circumference of the Cam be distributed. The cam disk can advantageously be constructed functionally and structurally as described above and in particular have a spiral groove, as described above.

A sensor is preferably present with which at least one basic position of the winding plate and / or the cam disc can be detected. The winding plate and / or the cam disk can thus be reproducibly positioned in a desired basic position in which the cam disk and / or the winding disk can be coupled or decoupled or the plunger device can be moved into the active position. Another method according to the invention for winding a cable into a reel with a device comprising a winding plate with several winding fingers, with a movable cam disk and with at least one plunger device, in particular with a device as described here, comprises at least the following steps: Rotating the winding plate or a movable cam disk in at least one basic position, this basic position preferably being detected with a sensor;

- Decoupling of the winding plate from the rotatable cam disk with the aid of a pusher device, the winding plate or the cam disk being locked at the same time;

- Setting the distance between the first winding finger and the second winding finger for setting the coil diameter on the cam, the cam or the winding plate being rotated by a drive device. When the winding plate is locked and uncoupled, the distance between the winding fingers can be easily adjusted with the aid of the single drive device of the device and with the aid of the cam. A further drive device for the winding plate can be dispensed with. Further advantages, features and details of the invention emerge from the following description, in which exemplary embodiments of the invention are described with reference to the drawings.

The cable processing machine 100 can have a further device 220 for winding a cable 10 into a reel as a second assembly, with a further reel transport device 250 and with a further reel binding device 260 are fed to the second assembly. The first assembly includes the device 20 for winding a cable 10 into a reel, the reel transport device 150 and the reel binding device 160. The reversing unit 145 pivots from the first assembly to the second assembly.

The device 20 for winding a cable 10 into a reel, which is described in detail in the following FIGS. 2 to 15, is arranged between the cable reversing device 140 and the reel transport device 150.

The device 20 for winding the cable 10 into a reel 15 comprises a winding plate 22 on which a plurality of winding fingers are movably arranged. The multiple winding fingers 30-35 are arranged with a constant arc length to one another on the winding plate 22, so that an approximately circular and thus stably wound coil 15 can be generated. The cable 10 has a trailing cable end 11 and a leading cable end 12.

After winding, the coil 15 has a plurality of turns N, the cable 10 being an electrical or optical cable. A plurality of fixing units 25a-25f for fixing the leading cable end 12 or the trailing cable end 11 are arranged on the winding plate 22. The further fixing units 25a-25f are arranged offset to the winding fingers 30-35.

A first holding unit 40 is arranged on a first winding finger 30, the cable 10 being able to be held in the region of the trailing cable end 11 with the first holding unit 40. The trailing cable end 11 extends from the cable end to the first holding unit 40 and has the length LI. A further holding unit 45 is arranged on a second winding finger 33, the cable 10 being able to be held in the region of the leading cable end 12 with the second holding unit 45. The leading cable end 12 extends from the cable end to the first holding unit 45 and has the length L2. The first winding finger 30 with the first holding unit 40 and the second winding finger 33 with the second holding unit 45 are arranged opposite on the winding plate 22. Support elements 37a-d are arranged on the remaining winding fingers 31, 32, 34, 35.

4 and 5 show a detailed illustration of the first winding finger 30 with the first holding unit 40 on the winding plate 22. The first holding unit 40 is arranged to be movable in direction Z along the first winding finger 30 and is with the locking unit 42a on the first winding finger 30 positionable. The first winding finger 30 has a winding area B, which extends in direction Z from the free end 30a of the first winding finger 30 to the first holding unit 40. Depending on the cable type of the cable 10, for example the coil height or the coil thickness (depending on the number of turns N of the coil 15) of the wound coil 15 can be preset. The locking unit 42a is detachable so that the winding finger 30 can be separated from the winding plate 22 and can be exchanged, for example, with a further winding finger which has a different dimension or shape to the first winding finger 30.

The holding unit 40 is designed as a passively clamping cable clamp. The cable clamp comprises a fixing device 42 for fixing the cable 10, the cable 10 being held in the state arranged in the cable clamp with a clamping force defined by a suspension 44a, 44b.

The fixing device 42 has a first gripper jaw 43a and a second gripper jaw 43b, between which the cable 10 can be fixed at least temporarily. The gripper jaws 43a, 43b are each in one

Gripper jaw housing 43c, 43d arranged to prevent possible damage to the cable 10 by the outer edges of the gripper jaws 43a, 43b and / or the springs 44a, 44b. The two gripper jaws 43a, 43b are arranged on the first winding finger 30. These can be transferred from an open state to a closed state, the transfer taking place without a drive using the cable 10, which is inserted and fixed between the two gripper jaws 43a, 43b. The gripper jaws 43a, 43b can be moved with the aid of the springs 44a, 44b, so that they can be moved independently at least from the open state into the closed state State can be transferred and different cable types and / or cable diameters can safely clamp.

The clamping force of the cable clamps of the holding unit 40 is dependent on the geometry of the gripper jaws 43a, 43b and the strength or dimensioning of the springs 44a, 44b, as shown in the sectional illustration in FIG. 5. The clamping force is selected so that the cable 10 is held securely during winding and can nevertheless be taken over by the multiple transfer grippers 153 in the subsequent process step without damage. An additional actuating element for opening can be dispensed with.

Such a winding finger is also arranged identically as a second winding finger 33 with the second holding unit 45 on the winding plate 22. The second winding finger 33 is arranged opposite the first winding finger 30 on the winding plate 22.

The holding units 40, 45 each have a support surface 38a, 38b which support the cable 10 in such a way that the turns N of the coil 15 are held together at least in sections. They enable the individual turns N of the wound coil 15 to be arranged in a structured manner.

As shown in detail in FIGS. 6 to 9, the device 20 has a drive device 50 for driving the winding plate 22. The drive device 50 has an electrically drivable motor 51 which is connected with the aid of a compensating coupling 53 and a drive shaft 52 and one with a cam disk 55 in the winding plate 22. The distance D of the multiple winding fingers 30 - 35 to one another on the winding plate 22 is adjustable, this also being done with the aid of the drive device 50. For this purpose, the movable cam disk 55 is arranged in the winding plate 22, the cam disk 55 having a spiral groove 56 in which the plurality of winding fingers 30-35 can move in order to set the distance D. The winding fingers 22 can be moved linearly along in guide rails 24 on the winding plate 22. A turning of the With the aid of the drive device 50, the cam disk 55 causes the winding fingers 30 - 35 to move in the groove 56, so that the winding fingers 30 - 35 can be guided radially in the direction K to the winding disk edge 23.

Those winding fingers 31, 32, 34 and 35, which do not have a holding unit 40, 45, instead have a support element 37a-d for supporting the wound coil 15. The support elements 37a-d support the cable 10 in such a way that the turns N of the coil 15 are held together at least in sections and enable the individual turns N of the wound coil 15 to be lined up in a sorted manner. The support elements 37a-d are in the directions Z along the respective winding fingers 31, 32, 34 and 35 are movably arranged and can be positioned with locking units 42a-f on the respective winding fingers 31, 32, 34 and 35. With the aid of the locking units 42a-f, winding fingers with different dimensions and / or shapes can be arranged on the winding plate 22. The respective winding fingers 31, 32, 34 and 35 have a winding area B, which extends in direction Z from the free end 31a, 32a, 34a, 35a of the respective winding fingers 31, 32, 34 and 35 to the respective support element 37a d, as shown in FIG. 9, for example.

3 already shows a first pusher device 60a and a further pusher device 60b of the device 20, with which the winding plate 22 can be coupled to the cam 55, the pusher devices 60a, 60b each being transferable from an active position to an inactive position and being stationary are arranged on the device 20. In the following, only the first plunger device 60a will be described. The further plunger device 60b is structurally identical and has the same function and is arranged opposite the first plunger device 60 on the winding plate 22.

FIGS. 10 and 11 now show the ram device 60a in detail. 10 shows the plunger device 60a in the inactive position or "rotating together", in which the cam 55 takes the winding plate 22 with it when the cam 55 is set in rotation by the drive device 55. FIG. 11 shows the plunger 60a in the active position or "decoupled + changing plate fixed". Is the changing plate 22 decoupled from the cam 55, then the winding plate 22 is locked at the same time on the device 20 and thus positioned non-rotatably in a basic position, so that the cam 55 can be set in rotation separately with the aid of the drive device 50 in order to set the distance D between the winding fingers.

The plunger device 60a has a pneumatically driven cylinder 65 for transferring the plunger device 60a from the active position into the inactive position. The ram device 60a has a locking ram 62 as a locking unit and the winding plate has a locking receptacle 26. The winding plate 22 is locked when the plunger device 60a is in the active position, the locking plunger 62 engaging in the locking receptacle 26.

A sensor 64 is arranged on the device 20, which sensor detects or records the basic position of the winding disc, in which the transfer of the coupling device 60a into the active position is possible. The sensor 64 consists, for example, of a contactless switch with an inductive measuring principle and a matching counterpart.

Furthermore, the first ram device 60a has a coupling device 27 for coupling the winding plate 22 to the cam disk 55. An actuator plunger 61 for actuating the coupling device 27 is arranged on the plunger device 60a. The pneumatic cylinder 65 simultaneously moves the actuator plunger 61 and the locking plunger 62 of the plunger device 60a. In the inactive position (FIG. 10), the pneumatic cylinder 65 is extended and the actuator plunger 61 and the locking plunger 62 are spaced from the winding plate 22. The winding plate 22 with the locking receptacle 26 can be rotated freely with the drive device 50.

The coupling device 27 comprises a belt 28 and a tensioning element 29a, both of which are arranged on the winding plate 22. The clamping element 29a is at least temporarily in operative connection with the clamping lever 29b mounted in the clamping joint 29c and with the aid of the ram device 60a Belt 28 can be brought, the force required for this being generated via the tension spring element 29d. The coupling device 27 is designed in such a way that when the belt 28 is tensioned, a frictional connection is established between the winding plate 22 and the cam disk 55. When the belt 27 is not tensioned, the frictional connection is released, or the friction is low enough to enable a relative rotation of the winding plate 22 and the cam disk 55. The pressing in of the tension spring element 29d and the associated reduction of the belt tension on the belt 28 takes place with the actuator plunger 61, which presses on a corresponding surface in the tensioning element 29a when the cylinder 65 is retracted. As a result, in addition to fixing the winding plate 22 via the locking plunger 62, the coupling device 27 is also actuated at the same time with the aid of the pneumatically driven cylinder 65.

In the active position of the ram device 60a (FIG. 11), the cylinder 65 is retracted. The locking unit 62 engages in the locking receptacle 26 and thus positions the winding plate 22 in a rotationally fixed manner in the basic position. At the same time, the tension spring element 29d is pressed in via the actuator plunger 61 and the coupling device 27 is thus actuated. The spring-loaded tensioning lever 29b is moved by the actuator plunger 61 in such a way that the tensioning element 29a is released from the belt 28, as a result of which the belt tension is reduced and thus the frictional engagement between the cam 55 and winding plate 22 is dissolved. This enables the cam disk 55 to rotate relative to the winding plate 22, the cam disk 55 being driven by the drive device 50 independently of the winding plate 22. Thus, the cam 55 and winding plate 22 are decoupled from one another and the winding plate 22 is positioned in its starting position in a rotationally fixed manner.

FIGS. 12 and 13 show the device 20 with an alternative coupling device 27a for the previously described plunger device 60a. This device 20 also has winding fingers, as disclosed in the figures described above. The alternative coupling device 27a has a tensioning lever 29e, a tensioning joint 29f and a tensioning spring element 29g which are arranged on the winding plate 22. The tensioning lever 29e can be actuated by the actuator plunger 61 as previously described in FIGS. 10 and 11. The coupling device 27a differs from the coupling device 27 in that the tensioning lever 29e comes into direct operative connection with the cam disk 55 in order to establish or release a frictional or form-fitting connection. The winding plate 22 is thus driven with the cam disk 55 which can be moved by the drive device 50. Otherwise, the two coupling devices 27, 27a are functionally identical. A belt and a tensioning element, as described above, are not necessary. Another structurally identical ram device 60b can optionally be used.

14 and 15 show one of the previously described fixing units 25a-25f in detail, reference being made to the fixing unit 25a in detail as a representative of the further fixing units. The fixing unit 25a is arranged on the winding plate 22 and has movable gripping elements 70a, 70b which can be transferred or pivoted from a fixing position (see FIG. 12) into a release position (see FIG. 13). The gripping elements 70a, 70b are passively sprung and can be moved by motor or actively and, for example, hold the leading end of the cable 11 in a stable manner when the cable 10 is being wound up into a reel 15. The device 20 has several transfer devices 75a-f. In the following, the transfer device 75b is described in detail as a representative of the multiple transfer devices 75a-f. The transfer device has a drive unit, such as a pneumatic cylinder 76b, and a transfer ram 77b arranged on the fixing unit 25a as a transfer unit. The pneumatic cylinder 76b has a piston 78b as an actuating unit, which can be brought into operative connection with the transfer ram 77b in order to open the gripping elements 70a, 70b.

The gripping elements 70a, 70b are connected to a spring element 71, the transfer device 75b being able to be brought into operative connection with the spring element 71. The end face of the piston 78b of the pneumatic cylinder 76 presses on the transfer ram 77b so that the transfer ram 77b tensions the spring element 71 in order to achieve the To transfer gripping elements 70a, 70b from the fixing position into the release position. When the gripping elements 70a, 70b are in their fixing position, this spring element 71 is pretensioned in such a way that the leading cable end 12 or the trailing cable end 11 are held in the fixing unit 25a. The transfer device 70b is separated from the winding plate 22 and arranged in a stationary manner on the device 20.

The method described below for winding the cable 10 into a reel 15 with the device 20 is also described with reference to FIGS. 2 to 15. The process can include the following process steps:

- Rotation of the winding plate 22 into a basic position, the output position being recorded or detected by a sensor 64;

- Locking of the winding plate 22 and simultaneous decoupling of the winding plate 22 from the cam 55, with the aid of the ram devices 60a, 60b;

- Adjustment of the distance D of the winding fingers 30-35 to one another for adjusting the coil diameter of the coil 15;

- Release of the locking of the winding plate 22 and simultaneous coupling of the winding plate 22 to the cam disk 55 connected to the drive device 50, with the aid of the ram devices 60a, 60b

- Feeding the leading cable end 11 of the cable 10 to the winding plate 22;

- Fixing the leading cable end 11 on one of the fixing units 25a-25f on the winding plate 22; - Insertion of the cable 10 in the area of the leading cable end 11 in the second holding unit 45 on the winding finger 33;

- Winding up the cable 10 to form a spool 15 with several turns N, the cam 55 being driven by the drive device 50 and taking the winding plate 22 with it; - Insertion of the cable 10 in the area of the trailing cable end 11 in the first holding unit 40 on the winding finger 30;

- stopping the winding plate 22;

- Cutting off the trailing calf end 11 of the cable 10 with a cutting device;

- Further rotation of the winding plate 22 with the drive device 50, so that the winding of the cable 10 is then completed.

16 shows a further embodiment according to the invention of the device 20a for winding the cable 10 into a reel 15. The device 20a comprises a further winding plate 22a on which several winding fingers 30-35 are movably arranged and a further movable cam disk 55a for setting the distance D of the multiple winding fingers 30-35. This device 20a also has winding fingers 30-35, as disclosed in the figures relating to device 20 described above. The device 20a additionally differs from the device 20 described in FIGS. 2 to 15 in that there is a drive device 50a with a drive shaft 52a, the winding plate 22a being directly connected to the drive shaft 52a. Furthermore, the cam disk 55a has a cam disk opening 55b, the drive shaft 52a extending through the cam disk opening 55b and the cam disk 55a being rotatably supported on the drive shaft 52a. A locking receptacle 26 is arranged on the cam disk 55a. The device 20a has a plunger device 60c with a further locking plunger 62a which is arranged on a pneumatic cylinder 65a. The cam disk 55a has a spiral groove 56a which is chosen to be flat enough so that self-locking occurs, ie a torque on the cam disk 55a is converted into a radial force which moves the winding fingers 30-35. Conversely, however, a radial force on the winding fingers does not cause any rotation of the cam disk 55a. In addition, by means of a slip clutch between the cam disk 55a and the winding plate 22a, the friction between these two components can be increased to such an extent that an undesired relative rotation of the cam plate / winding plate occurs when there is a strong Braking and / or strong acceleration is reliably prevented (not shown). This device 20a can also have a plunger device with an actuator plunger and / or a matching coupling device, as described above, wherein this coupling device can be arranged on the cam disk 55a (not shown).
