Description

Twisting apparatus and twisting head arrangement and method for twisting or stranding cables
Technical Field
The present invention relates to a twist head apparatus for twisting or stranding cables and/or optical cables; a method for twisting or stranding cables and/or cables through the twist head apparatus; a twisting apparatus for twisting or stranding cables and/or cables; a method for stranding or twisting a cable and/or a fiber optic cable by the twisting apparatus; computer-implemented method for automatically determining and generating data recording and/or movement commands for a twisting apparatus according to the preamble of the independent claim.
Background
In the production of wire harnesses, a distinction must be made between two production processes, i.e. twisting or stranding. However, these two terms are often confused in the literature. In this document, the twisting process is understood as: two or more cables are twisted around each other, in which case a twist lay is created, which indicates the length of a single 360 turn or turn. In order to achieve a specific twist characteristic, in the simplest case during manufacture, the strand must be twisted excessively so that it is in the desired final twisted state after the relaxation process. This approach is well suited for most applications. Typically, to make a twisted wire harness in an automotive structure, a twist of insulated copper conductors is commonly employed.
In contrast, only a small portion of the wire harness is manufactured using the stranding principle. Here, the twisting process is understood to be: two or more cables are placed around each other. The lay length, i.e. the distance from one winding to the next, is predetermined by a twisting shuttle which moves the cable end from one cable end along the cable to be twisted while the cables to be twisted are placed around each other. The twisting process places much less stress on the cables to be twisted because the twist of the individual cables is absorbed or compensated for during the twisting process. This method is suitable for very sensitive situations, such as twisting very thin cables into a bundle. Generally, a twisted wire harness is used for a sheath cable.
When two or more cables are installed simultaneously in a wiring harness or when special specifications are imposed on the wiring harness, twisted or litz wires are generally used. Typically, twisted wires are used in the automotive field or in equipment manufacturing. In cases where the cable must have anti-electromagnetic interference capabilities (electromagnetic compatibility (EMV)) with respect to its surroundings, twisted or stranded wires are used (e.g., twisted pair if two cables are stranded into a bundle).
During the manufacturing process, the cables to be twisted or twisted with respect to one another are clamped in a rotatably supported twisting or twisting head. The clamped cables are then twisted or rotated around each other, thereby producing a bundle of wires (so-called twisted pair wires) as a final product.
DE 19631770 a1 shows a method and a device for twisting at least two individual cables. The cable ends of the cables are clamped in each case in a rotatable untwisting clamp of the first twisting head on the one hand and in a twisting clamp of the second twisting head which is jointly rotatable about the twisting axis on the other hand. During the twisting process, a twist shuttle located between two separate cables moves along the cables from the twist clamp to the untwist clamp. In this case, the speed of movement of the twist shuttle is regulated by the controller.
A disadvantage of the above solution is that the twist shuttle can only move from the twist clamp towards the untwist clamp during twisting. Therefore, the twist shuttle must be moved back from the untwisting jig to the twisting jig before each new twisting process. This adds time consumption in manufacturing.
DE 202016103444U 1 shows a device for producing a wire harness which is clamped between two tensioning devices. One of the tensioning devices has a rotatably mounted support and a housing, wherein the rotatably mounted support has a rotatably mounted clamping portion for each cable to be twisted. During the twisting process, the support and the gripping portion are driven in rotation by a drive. The clamping portion is operatively connected to the housing by a transmission such that the clamping device rotates at a specific transmission ratio with respect to the direction of rotation of the support.
A disadvantage of the aforementioned solution is that during twisting there is always a fixed transmission ratio and a predetermined direction of rotation between the rotating clamping part and the rotating support, so that the wire types that can be twisted with the device are limited.

This object is achieved by the devices, apparatuses and methods defined in the independent claims. Advantageous developments are presented in the figures, the description and in particular the dependent claims.
The twisting head device for twisting or stranding cables or optical cables according to the present invention includes a twisting rotor, a twisting rotor driving device for driving the twisting rotor, a first gripper device rotatably disposed on the twisting rotor, at least another gripper device rotatably disposed on the twisting rotor. The twisting rotor is rotatably disposed on the twisting head device and has a rotation axis. At least the first gripper means can be driven by means of a gripper drive and a drive shaft. The drive shaft extends at least partially through the twist rotor.
In this twisting head arrangement, at least the first gripper arrangement can be driven independently of the twisting rotor. This allows, for example, the twisting rotor and the first and second gripper devices to be driven independently of each other, in particular at different speeds or rotational directions. The twist rotor drive is mechanically decoupled from the gripper drive. Accordingly, various or vulnerable cables and/or cables may be repeatedly stranded or twisted.
The drive shaft extending at least partially in the twisting rotor allows a compact construction of the twisting head arrangement while increasing the possibilities and flexibility of the drive scheme of the twisting rotor drive and the gripper drive.
Advantageously, the drive shaft is arranged coaxially with the rotational axis of the twisting rotor. Thus, the drive shaft and the twisting rotor are arranged around the same rotation axis, whereby the twisting head device can be constructed compactly.
Preferably, at least the first gripper arrangement is arranged on the first gripper shaft and has a first gripper rotation axis. The arrangement on the first gripper shaft is such that the first gripper means can rotate. This ensures a simple and stable design of the first gripper device on the twisting head device, so that only low centrifugal forces act on the gripper device.
Advantageously, the first gripper shaft extends at least partially into the twisting rotor. Whereby the stable construction of the twist head apparatus is improved. At the same time, this allows for an overall compact construction of the twist head arrangement.
Furthermore, advantageously, the first gripper rotation axis is spaced apart from the rotation axis of the twisting rotor. The spacing of the axis of rotation of the twisting rotor from the first gripper rotation axis of the first gripper arrangement results in a defined geometry in the twisting head arrangement.
Advantageously, the first gripper rotation axis is radially spaced from the rotation axis of the twisting rotor. This allows the first gripper shaft to move in a circular path around the twisting rotor, which makes simple twisting or stranding of the cables possible.
Preferably, the twisting rotor has a hollow rotor shaft, wherein the drive shaft is arranged at least partially in the hollow rotor shaft. The arrangement of the drive shaft in the hollow shaft of the rotor makes possible a compact construction of the twist head arrangement, wherein the overall system has a low inertia, thereby increasing the operational stability during operation.
Advantageously, the drive shaft extends through the twisting rotor, wherein at least one drive shaft bearing is arranged at least partially in the twisting rotor, the drive shaft bearing rotatably supporting the drive shaft. The drive shaft is thus at least partially supported in the twisting rotor. This results in improved support stability of the drive shaft in the twist head apparatus. The positioning of the drive shaft support means of the drive shaft in the twist rotor may also improve the vibration damping of the drive shaft. Thereby, the quality can be improved in the manufacturing process of the cable to be twisted or stranded.
Advantageously, the drive shaft is rotatably arranged with respect to the rotatable twisting rotor, whereby different rotational directions and/or rotational speeds of the drive shaft and the twisting rotor can be achieved.
Preferably, the at least one further gripper device can be driven by means of a gripper drive and a drive shaft. The further gripper arrangement can thereby also be driven independently of the twisting rotor, thereby further improving the quality in the manufacture of the cable to be twisted or stranded.
Advantageously, the further gripper device is arranged on a further gripper shaft. The arrangement on the further gripper shaft is such that the further gripper arrangement can be rotated relative to the twisting rotor.
Furthermore, advantageously, the further gripper shaft extends at least partially in the twisting rotor and has a further gripper rotation axis, whereby a compact construction of the twisting head arrangement can also be achieved by means of a plurality of gripper arrangements.
Furthermore, advantageously, the further gripper rotation axis is spaced apart from the rotation axis of the twisting rotor, whereby a defined geometry of the twisting head arrangement can be achieved.
Preferably, at least one gripper support means is arranged in the twisting rotor, the at least one gripper support means rotatably supporting at least the first gripper means. This enables a simple support of the first gripper arrangement in the twisting head arrangement and a compact construction of the twisting head arrangement.
Advantageously, the further gripper support means also rotatably support the further gripper means in the twisting rotor, so that a complex rotation system can be simply supported in the twisting rotor.
Preferably, the twist rotor has a connecting shaft establishing an operative connection between the drive shaft and at least the first gripper shaft. The operative connection can be established by means of at least one first transmission. The first transmission is arranged between the drive shaft and the connecting shaft. The connecting shaft is thus spatially separated in the twisting rotor relative to the drive shaft, but can nevertheless be driven by means of the gripper drive.
Advantageously, the operative connection can be established by means of a further transmission arranged between the connecting shaft and at least the first gripper shaft. Thereby, the first gripper shaft can be simply driven by the gripper driving means.
Furthermore, advantageously, the effective connection can be established by means of a further transmission which is arranged between the connecting shaft and at least the first gripper shaft and between the connecting shaft and the further gripper shaft. In addition to the first gripper shaft, it is also possible to simply drive the other gripper shaft by means of only one gripper drive.
Preferably, a connecting shaft supporting device is disposed in the twisting rotor, the connecting shaft supporting device rotatably supporting the connecting shaft. This results in an increased bearing stability and thus an increased operational stability of the connecting shaft in the twisted rotor.
Preferably, the gripper drive and the twisting rotor drive are at least partially arranged on a common fixture. The individual drives can be mounted independently of one another on a common fastening device.
Advantageously, the gripper drive and the twisting rotor drive are connected to a controller device. The gripper drive and the twist rotor drive are therefore each connected independently of one another to the controller device and can each receive control commands or movement commands independently of one another.
Furthermore, it is advantageous if the gripper drive and the twisting rotor drive are arranged at least partially on a common fastening device. By this arrangement, the gripper drive and the twisting rotor drive can be fixed to the twisting head arrangement in a simple and space-saving manner. In addition, the gripper drive and the twist rotor drive are connected to the controller device. Thus, control commands or movement commands may be sent independently but simultaneously from the controller device to the gripper drive and the twist rotor drive, respectively.
Preferably, the at least first gripper device has at least one gripper for gripping the cable end of the cable, whereby the cable end of the cable can be simply gripped.
Advantageously, the at least one gripper has a closing sleeve guided in the axial direction to at least partially enclose the at least one gripper. A closure sleeve surrounds the at least one gripper. This makes it possible to simply and firmly clamp the cable end of the cable.
Advantageously, the further gripper device has at least one further gripper for gripping the cable end of the further cable, whereby the cable end of the further cable can be simply gripped.
Advantageously, the at least one further holder has a closing sleeve guided in the axial direction to at least partially enclose the at least one further holder. This makes it possible to simply and firmly clamp the cable end of the cable.
Another aspect of the invention relates to a method for twisting or stranding cables and/or cables, having at least the following steps:
-clamping a first cable end of a first cable into a first gripper device;
-clamping at least one first cable end of a further cable into a further gripper device;
-driving the twisting rotor by a twisting rotor drive means in rotation about the axis of rotation of the twisting rotor by a first number of revolutions;
-driving at least the first gripper means by means of the gripper drive means to rotate around the first gripper rotation axis with another number of revolutions;
-driving at least one further gripper device by means of the gripper drive device around a further gripper rotation axis with the further number of revolutions, wherein the first number of revolutions and the further number of revolutions are specified by the controller device.
The cables to be twisted or twisted can thereby be rotated about their respective longitudinal axes and relative to one another about the axis of rotation of the twisting rotor, so that a clamped cable twisting or twisting can be achieved. In this case, the optical cable and/or the cable sensitive to the number of revolutions during the stranding or twisting process and the mechanical load generated thereby may be repeatedly stranded or twisted with little waste during manufacturing.
Advantageously, the method is carried out by means of the twisting head arrangement described above, whereby a particularly high-quality wire bundle is produced.
Preferably, the other rotation number is 50% to 98% of the first rotation number. The different number of turns allows for simultaneous reverse twisting of the cables, for example, during twisting.
Advantageously, the further revolution is 60% to 70% of the first revolution, whereby the reverse twist can be improved during twisting. Thus, the twisting rotor rotates around the rotation axis with a higher number of revolutions than the rotation of the first gripper arrangement or the further gripper arrangement around its rotation axis. Thereby saving time in the twisting process or twisting process.
Preferably, the twisting rotor and the at least first gripper arrangement are driven in the same rotational direction or the twisting rotor and the at least first gripper arrangement are driven in opposite rotational directions, whereby a reverse twisting can be integrated during twisting and/or specific properties in the bundle can be set.
Another aspect of the present invention relates to a twisting apparatus for twisting or stranding cables or optical cables, the twisting apparatus including a first twist head device having a first twist rotor and a clamping device. The first twist rotor is rotatably disposed on the first twist head device, and the first twist head device and the clamping device are spaced apart from each other. The twisting apparatus has a twist shuttle movable at least from a first position to another position in a direction between the first twist head device and the clamping device. The twisting device has a controller device for controlling at least a first twisting head device, wherein the twisting device has at least one first sensor device for detecting the position of the twisting shuttle.
The detection of the position of the twist shuttle allows the position to be communicated to an operator. Thus, an operator of the twisting apparatus, for example located in a control room remote from the twisting apparatus, can determine the position of the twist shuttle. Based on this position, the operator can decide whether the twisting process or the stranding process can be started on the twisting apparatus. Accordingly, the wire harness may be manufactured using a twisting process or using a twisting process.
Since the position of the twist shuttle is detected, both manufacturing processes can be performed on the same equipment without the operator of the twisting equipment having to be directly resident at the machine, for example to check the position of the twist shuttle.
Typically, the twist shuttle is designed as a bolt, whereby the twist shuttle can be simply manufactured.
Advantageously, the first sensor arrangement is connected to a controller arrangement of the twisting device for exchanging sensor data. Sensor data, for example relating to the position of the twist shuttle, can thus be transmitted to the controller device and can be collected in the controller device and, if necessary, can be further processed there. These sensor data include, but are not limited to, data records relating to positioning information, position information, or status information of the twist shuttle.
As described herein, the twisting apparatus advantageously has at least one twisting head arrangement as the first twisting head arrangement. The twisting head device has a twisting rotor drive and a gripper drive. These can be controlled independently of each other by the controller means of the twisting apparatus. This makes it possible to perform a twisting process or a stranding process on the twisting apparatus. The first twist head device has a particularly compact construction. This in turn facilitates a compact construction of the twisting apparatus. Thus, the manufacturers of bundles of different kinds of cables and/or optical cables only need one device for stranding or twisting the cables, which greatly reduces the production costs of the production plant.
Preferably, the twisting apparatus has a first positioning device on which the twist shuttle is arranged. The twisting shuttle can be moved to a twisting position by means of a first positioning device. Thus, the twisting apparatus allows for a twisting process when the twisting shuttle is in the twisting position.
Alternatively or additionally, the twist shuttle may be moved to a rest position by the positioning device. Thus, the twisting apparatus allows for a twisting process when the twist shuttle is in a rest position. Furthermore, the twisting shuttle may simply move from the twisting position to the rest position and vice versa, whereby the twisting process or twisting process may be performed on the twisting apparatus.
Any position of the twisting shuttle between the cables to be twisted is referred to as a twisted position. Any position of the twisting shuttle that does not play any role in the twisting process is referred to as the rest position of the twisting shuttle.
Advantageously, the twisting shuttle may be linearly disposed in a twisting position or a rest position, whereby the movement of the twisting shuttle may be easily controlled. The twisting shuttle is then inserted between the cables to be twisted from one side of the twisting apparatus in a typical manner.
Advantageously, the positioning device is designed such that the twisting shuttle can be placed between the cables to be twisted from a position above the twisting head device in a direction towards the cables to be twisted. Whereby the operator has easier access to the twisting apparatus, for example in maintenance work. In addition, if the twisted wire harness falls into a collection container of the twisting apparatus after being released, the twisted wire harness does not collide with the twisting shuttle after the twisting process is finished.
Alternatively or additionally, a support device is arranged on the first positioning device, wherein the support device can be brought into a support position and/or into a rest position. The support device supports the cables during the stranding or twisting process, whereby the cables to be stranded or twisted hang down less and are thus subjected to less mechanical stress. This additionally improves the quality of the wire harness.
Any position of the support device against the cable to be stranded or twisted is referred to as a support position. For example, the cable to be stranded or twisted is located on the support device in a state of being clamped in the twisting device. Any position of the support device that does not play any role in the manufacturing process is referred to as the rest position of the support device.
Advantageously, the support device can be pivoted into a support position and into a rest position. The support device can thereby be moved particularly easily and positioned precisely on the first positioning device of the twisting apparatus.
Preferably, the twisting device has a further support means for supporting the at least one cable, wherein the further support means is movable. Thereby allowing the cable to be supported in another position.
Advantageously, the further support device is arranged on the further positioning device and can be brought into a support position and a rest position. The further support device can thus be moved independently of the twisting shuttle by means of the further positioning device.
Advantageously, the further support means is pivotable. The further support device can thus be moved particularly easily and positioned precisely on the further positioning device of the twisting apparatus.
Preferably, the twisting apparatus has a twist shuttle drive for positioning the twist shuttle from the twist position to the rest position, whereby the twist shuttle can be easily moved out of the twist position.
Advantageously, the twist shuttle drive is designed for positioning the twist shuttle from a rest position to a twist position, whereby an automatic positioning of the twist shuttle can be achieved.
Alternatively or additionally, the twisting apparatus has a support device drive for positioning the support device from the support position into the rest position, whereby the support device can be easily moved out of the support position.
Advantageously, the support device drive is designed for positioning the support device from a rest position into a support position, whereby the support device can be moved precisely and reproducibly to the cable to be stranded or twisted.
Advantageously, the support device drive is designed for pivoting the support device from a rest position into a support position, whereby the support device can be moved particularly easily and reproducibly to the cable to be stranded or twisted.
Advantageously, at least one of the two drives is connected to the controller device. This allows exchange of control data between the controller device and the twist shuttle drive and/or the support device drive, whereby the control data may cause the twist shuttle and/or the support device and/or the further support device to be repeatedly moved between or at the cables.
Advantageously, the twisting apparatus has a further support device drive for positioning the further support device, the further support device drive being connected to the controller device. This allows the cable to be supported at least another location in the twisting apparatus.
Advantageously, the further support device drive is designed for pivoting the further support device from the rest position into the support position, whereby the further support device can be moved particularly easily and reproducibly to the cable to be stranded or twisted.
Preferably, the twisting device has at least one second sensor device, which is designed to detect the position of the support device, whereby the support position at the cable to be twisted or stranded and the rest position of the support device can be detected. This enables the support means to be positioned reproducibly.
Advantageously, the second sensor device is connected to the controller device for exchanging sensor data. These sensor data include, but are not limited to, data records relating to positioning information, position information or status information of the support device. The sensor data may be processed in the controller device and then used for further control of the support device. This allows to accurately support the cable to be stranded or twisted, whereby sagging of the cable in the twisting apparatus can be prevented, especially in case of very long cables, thereby reducing the mechanical load on the cable during stranding or twisting.
Advantageously, the twisting device has at least one third sensor device, the second sensor device being designed to detect the position of the further support device, whereby the support position at the cable to be twisted or stranded and the rest position of the further support device can be detected.
Advantageously, the third sensor device is connected to the controller device for exchanging sensor data. These sensor data include, but are not limited to, data records relating to positioning information, position information or status information of another support device. The sensor data may be processed in the controller device and then used for further control of another support device. This allows the cable to be stranded or twisted to be supported precisely at another location, whereby sagging of the cable in the twisting apparatus can be prevented, especially in the case of very long cables.
Preferably, the first positioning device of the twisting shuttle is movably arranged on the first guide device, wherein the twisting shuttle is movable in a direction between the clamping device and the first twisting head device. Thus, the twist shuttle may be movable from the clamping device towards the first twist head device and may be movable from the first twist head device towards the clamping device.
Advantageously, the first positioning device has a drive device for moving the first positioning device on the first guide device, whereby the twisting shuttle can be automatically moved between the first twisting head device and the clamping device.
Advantageously, the twisting shuttle is arranged on the support means. This allows a simplified construction of the twist shuttle and the support means on the first positioning means. For example, the supporting device and the twisting shuttle are integrally configured, thereby simultaneously twisting and supporting the cable.
The twisting shuttle is advantageous because it allows a particularly precise twisting of the cable to be twisted.
Alternatively or additionally, the support device is designed in a T-shape, whereby the cable to be stranded can be held particularly precisely or stranded and held.
Alternatively or additionally, the positioning device of the support device is movably arranged on the first guide device, wherein the support device is movable in a direction between the clamping device and the first twisting head device.
Advantageously, the positioning device has a drive device for moving the positioning device on the first guide device, so that the support device can be automatically moved between the first twisting head device and the clamping device.
Advantageously, the further positioning device of the further supporting device is movably arranged on the first guiding device, wherein the further supporting device is movable in a direction between the clamping device and the first twisting head device.
Advantageously, the further positioning device has a drive device for moving the further positioning device on the first guide device, whereby the further support device can be automatically moved between the first twisting head device and the clamping device.
Preferably, the clamping device is designed as a further twist head device and is connected to the controller device for controlling at least the further twist head device. This increases the flexibility of the twisting apparatus.
Advantageously, the clamping device is configured as a further twisting head device here, which makes a compact configuration of the twisting apparatus possible.
Preferably, the twisting device has an operator means and a memory means, the operator means and the memory means being connected to the controller means. This makes it possible on the one hand to calculate a new data recording or movement command in the arithmetic unit and on the other hand to transmit the data recording or movement command stored in the memory unit to the controller device.
Advantageously, at least the sensor data of the first sensor device of the twist shuttle can be processed by means of an arithmetic device. In this way, for example, sensor data of at least the first sensor device can be processed into control commands or movement commands for controlling the position or positioning of the twist shuttle.
Alternatively or additionally, at least the sensor data of the second sensor device of the support device can be processed by means of an arithmetic device. In this way, for example, the sensor data of at least the second sensor device can be processed into data records or movement commands for controlling the position or positioning of the support device.
Advantageously, the sensor data of the first sensor device can be stored in a memory device, whereby the stored sensor data can be accessed when necessary.
Alternatively or additionally, the sensor data of the second sensor device may be stored in a memory device, whereby the stored sensor data may be accessed as necessary.
Advantageously, at least the sensor data of the third sensor device of the twist shuttle can be processed by means of an arithmetic device. In this way, for example, sensor data of at least a third sensor device can be processed into control commands or movement commands for controlling the position or positioning of the further support device.
Advantageously, the sensor data of the third sensor device can be stored in the memory device, whereby the stored sensor data can be accessed when necessary.
Preferably, the twisting apparatus has another guide device to linearly move at least the clamping device in a direction between the first twisting head device and the clamping device. This allows at least the clamping device to be positioned so as to keep the cable tension constant during the twisting or twisting process.
Optionally, the twisting apparatus has another guide device to linearly move at least the first twist head device in a direction between the first twist head device and the clamping device. This allows the at least first twist head device to be positioned so as to maintain a constant cable tension during the twisting or twisting process.
Advantageously, the first wringer head device and the clamping device are mounted on the other guide device so as to be linearly displaceable in the direction between the first wringer head device and the clamping device. This allows the first twisting head device and the clamping device to move simultaneously or symmetrically during twisting or stranding.
Advantageously, the twisting device has at least one further sensor device, which detects the position of the first twisting head device on the further guide device and transmits sensor data to the controller device. This allows the sensor data to be subsequently processed in the operator device and stored in the memory device. This improves the quality of the produced wire harness.
Alternatively or additionally, the twisting device has at least one further sensor device which detects the position of the clamping device on the further guide device and transmits sensor data to the controller device. This allows the sensor data to be subsequently processed in the operator device and stored in the memory device. Thus, a completely repeatable movement of the first twist head device and the clamping device may be achieved, whereby a twisted or twisted wire bundle may be manufactured reproducibly.
Another aspect of the invention relates to a method for stranding or twisting at least two electric and/or optical cables by means of a twisting apparatus having at least one first twisting head device comprising a twisting rotor. The method at least comprises the following steps:

-detecting at least one position of the twist shuttle by means of a first sensor device and determining a twist position or a rest position of the twist shuttle;
-performing a twisting process or a twisting process at the at least two cables, wherein the twisting process is performed when the twisting shuttle is in the twisting position and the twisting process is performed when the twisting shuttle is in the rest position.
The detection of the position of the twist shuttle allows the position to be communicated to an operator of the twisting apparatus. Thus, an operator, for example, located in a control room remote from the twisting apparatus, can determine the position of the twist shuttle. Based on this position, the operator can decide whether the twisting process or the stranding process can be started on the twisting apparatus.
Advantageously, the twisting apparatus is a twisting apparatus as described herein and has a first twisting head arrangement with a twisting rotor as described herein, whereby the twisting process or twisting process can be performed fully automatically.
Advantageously, the two cables are clamped parallel to each other in the twisting device, so that the wires to be twisted or the cables to be twisted can be easily formed.
Preferably, at least the twisting shuttle is moved to the twisting position before the twisting process is performed, or the twisting shuttle is moved to the rest position before the twisting process is performed. The process for manufacturing the wire harness predetermined by the operator of the twisting apparatus can thereby be automatically performed.
Preferably, the position of the support means is detected by second sensor means. It can thus easily be decided whether the support means should be used during the twisting process or twisting process.
Advantageously, the support device is moved from the rest position into the support position, so that the support device can then abut and support the cable to be stranded or twisted.
Advantageously, the support device is pivoted from the rest position into the support position, thereby performing a simple movement.
Advantageously, the support device is moved from the first support position to the other support position during the twisting process or twisting process, so that the cable to be twisted or twisted always bears against the support device and thus the quality of the twisted or twisted cable strand produced is increased.
Preferably, the twisting shuttle is moved in a direction away from the clamping device and towards the first twisting head device during twisting, whereby the lay length in the bundle to be twisted may be adjusted.
Advantageously, the positioning of the twist shuttle in this direction is determined by a further sensor device, and the sensor data is transmitted to the controller device and further processed by the controller device. This allows the lay length to be accurately adjusted or calculated in the wire harness to be stranded, thereby improving the quality of the stranded wire harness. The calculation includes, for example, the shortening of the cable pairs during twisting or twisting and the length compensation achieved by the clamping device being moved toward the first twisting head device.
Preferably, the support means moves in a direction away from the clamping means and towards the first twisting head means during twisting or during twisting. This allows the cable to be stranded or twisted to be constantly supported, in particular in the region of the twisting shuttle.
Advantageously, the positioning of the support device in this direction is determined by a further sensor device, and the sensor data is transmitted to the controller device and further processed by the controller device. The support device can be precisely controlled by means of the determined or further processed sensor data, as a result of which the cable to be stranded or twisted can be stably supported, so that the quality of the produced wire harness is improved.
Preferably, the twisting shuttle will move to a rest position after the twisting process, whereby the twisted strands may simply be output from the twisting apparatus.
Alternatively or additionally, the support device is moved to a rest position after the twisting process or the twisting process, whereby the twisted wire bundle can simply be output from the twisting apparatus.
Advantageously, the movement into the rest position is triggered by the end of the twisting process or twisting process, thereby speeding up the manufacturing process during twisting or twisting.
Preferably, the twisting apparatus has a second twisting head arrangement comprising a second twisting rotor having at least one first gripper arrangement and a further gripper arrangement. During twisting, the twisting rotor of the first twisting head arrangement rotates and rotates the first gripper arrangement and the further gripper arrangement of the second twisting head arrangement. The twisting shuttle moves in a direction between the first twisting head device and the second twisting head device. This allows for a precise twisting process in the first direction between the first twisting head arrangement and the second twisting head arrangement.
Preferably, the first twist head device has a first gripper device and a further gripper device. After the stranding process, the other two cables are clamped in the twisting apparatus, and then the first gripper device of the first twisting head device and the other gripper device are rotated. The twisting rotor of the second twisting head device rotates, wherein the twisting shuttle moves in a direction between the first twisting head device and the second twisting head device. This allows the twisting process to be performed in the opposite direction to the aforementioned direction. Thereby allowing a twisting process to be performed in both directions between the first and second twisting head arrangements.
Another aspect of the invention relates to a computer-implemented method for automatically determining and generating data recording and/or movement commands for controlling at least one twisting head arrangement, in particular as described herein, or for controlling a twisting apparatus, in particular as described herein, the computer-implemented method performing a method, in particular as described herein, for twisting or stranding at least two cables. Here, the position of the twist shuttle is detected by the first sensor device and at least one data recording and/or movement command is generated and stored, which data recording and/or movement command indicates the position of the twist shuttle. The position of the twist shuttle can thus be determined completely automatically and can be monitored and processed.
Alternatively or additionally, the at least one generated and stored data record and/or movement command indicates movement of the twist shuttle from the rest position to the twist position. The twist shuttle can be repeatedly moved into the twist position by means of at least one generated and stored data recording and/or movement command.
Advantageously, the at least one generated and stored data record and/or movement command indicates a movement of the twist shuttle from the twist position to the rest position. The twist shuttle can be repeatedly moved into the rest position by means of at least one generated and stored data recording and/or movement command.
Advantageously, the position of the support means is detected by the second sensor means and at least one data recording and/or movement command is generated and stored, which data recording and/or movement command is indicative of the position of the support means. The position of the support means can thus be determined completely automatically and the position of the twist shuttle and the support means can be monitored and processed.
Alternatively or additionally, the at least one generated and stored data record and/or movement command indicates a movement of the support device from the rest position to the support position. The support device can thus be guided precisely onto the cable.
Advantageously, the at least one generated and stored data record and/or movement command is indicative of a movement of the support means from the support position to the rest position, whereby the support means may be controlled away from the cable.
Advantageously, the position of the further support means is detected by the third sensor means and at least one data recording and/or movement command is generated and stored, which data recording and/or movement command indicates the position of the further support means. The position of the further support means can thus be determined completely automatically and the position of the twist shuttle, the support means and the further support means can be monitored and processed.
Alternatively or additionally, the at least one generated and stored data record and/or movement command indicates a movement of the further support device from the rest position to the support position. The further support device can thus be guided precisely onto the cable.

Detailed Description
Fig. 1-3 illustrate a twisting apparatus 15 for twisting or stranding a cable or fiber optic cable 16. The twisting apparatus 15 comprises a base 17 on which a first twisting head device 20 with a twisting rotor 22 and a clamping device 28 are arranged. The twisting rotor 22 has a twisting rotor drive 21 and is arranged on the first twisting head arrangement 20 rotatably about a rotation axis 23. The first twist head device 20 is spaced from the clamping device 28.
The twisting apparatus 15 has a first guide 18, on which first guide 18 a positioning device 70 is arranged. The guide device 18 has a guide rail 19, on which guide rail 19 a positioning device 70 is movably arranged in the direction between the clamping device 28 and the first twist head device 20. The guide rail 19 extends from the first twist head device 20 to the clamping device 28 and further beyond the clamping device 28, whereby the positioning device 70 may be positioned beyond the clamping device 28 and outside the area between the twist head device 20 and the clamping device 28. The positioning device 70 has a drive 75 for moving the positioning device 70 along the guide rail 19, wherein the drive has a servomotor 76.
The servo motors are typically equipped with resolvers whose high resolution can detect the precise number of revolutions and angular position on the motor shaft from a starting position and provide to the controller device 60. When each servo motor is equipped with a position detection function, even a complex automation system having a plurality of servo motors can be controlled very accurately and on time. Advantageously, a brushless resolver is used, which is an ideal rotor position encoder for position feedback of brushless motors (servomotors), robots or direct drives.
Instead of a resolver, a rotary encoder, an angular encoder or an encoder may be used.
On the positioning device 70, a twisting shuttle 65 and a support device 85 are arranged, which can be moved from a first position to another position in the direction between the first twisting head device 20 and the clamping device 28. The movement of the twist shuttle 65 and the support device 85 in this direction is determined by the further sensor device 68 and the sensor data is transmitted to the controller device 60 and further processed by the controller device 60. Here, the twisting shuttle 65 and the support device 85 can also be moved along the guide rail 19 in the region between the twisting head device 20 and the clamping device 28. In an alternative embodiment, only the support means 85 is located on the positioning means 70.
The twisting device 15 has a first feed 29 and a second feed 34, which in the use according to the invention are arranged above the cable 16 or above the axis of rotation 23, respectively. The feeding devices 29, 34 in the use according to the invention lead the cable 16 from a cable entry area arranged in the rear region of the twisting apparatus 15 to the two gripper devices 30, 45 and the clamping device 28 (not shown). The feeding device 34 is fixedly arranged on the twisting apparatus 15 with respect to the first twist head device 20. The feed device 29 is arranged above the clamping device 28 in a fixed manner relative to the clamping device 28 and can be moved together with the clamping device 28 in the longitudinal direction of the twisting apparatus 15 by means of a servomotor and set to the thread length to be processed.
The cable 16 is clamped between the first twist head assembly 20 and the clamping assembly 28 and is twisted or stranded as described below. This results in a reduced distance between the first wringer head device 20 and the clamping device 28.
The twisting device 15 has a further guide 100, the further guide 100 having a further guide rail 101 and a drive 102, wherein the distance between the first twisting head device 20 and the clamping device 28 can be compensated for by means of the guide 100 during the twisting process or twisting process. The clamping device 28 is arranged movably on the other guide rail 101. The clamping device 28 can thus be moved by means of the drive 102 along the guide rail 101 in the direction between the clamping device 28 and the first twisting head device 20, whereby length compensation can be carried out when twisting or stranding the cables 16.
The twisting device 15 has a controller device 60, an arithmetic device 61 and a memory device 62. The controller device 60 of the twisting apparatus 15 is electrically connected to a driving device or driver described below. The controller device 60 receives sensor data from the drive device or the sensor device of the drive and processes the sensor data in the arithmetic device 61 into data recording or movement commands or control commands, which are in turn sent to the drive device or the drive.
The twisting device 15 has a sensor device 110 which detects the position of the clamping device 28 on the other guide device 100 and transmits sensor data to the controller device 60. The further sensor device 110 is arranged on a drive 102, which is designed as a servomotor 111 having a resolver 115.
The clamping device 28 has a first clamping gripper and a second clamping gripper for clamping the cable 16, which are each rotatably supported and driven by a clamping drive (not shown). The clamping grippers have a common axis of rotation and can be rotated jointly about the common axis of rotation. The clamping device 28 has a clamping rotor which can be driven in rotation by a clamping drive. The clamping drive has a servomotor with a resolver. By means of the resolver, the number of revolutions and the angular position on the servo motor shaft can be determined from the starting position and the resolver data can be transmitted as sensor data to the controller device 60 of the twisting apparatus 15.
The components shown in fig. 1 to 3 with the reference symbols 26, 40, 41, 56, 80, 10, 95-97 are described below with reference to fig. 8.
Fig. 4 to 7 show the positioning device 70 and the twist head device 20 of the twisting apparatus 15 in a cross-sectional view along line a-a of fig. 1.
The positioning device 70 has a twist shuttle drive 72 for positioning the twist shuttle 65 from the twisted position to the rest position. The twist shuttle 65 is either in the twisting position (see fig. 4 and 5, also referred to as the extended working position) or in the rest position (see fig. 6 and 7, also referred to as the retracted starting position). The twist shuttle drive 72 has a linear guide, which is embodied here as a lifting cylinder 73. The twisting shuttle 65 is arranged at one of both ends of the lifting cylinder 73. Accordingly, twist shuttle 65 may move from a twisted position between cables 16 to a rest position outside of cables 16 via linear motion, and may move from a rest position outside of cables 16 to a twisted position between cables 16 via linear motion. The twist shuttle 65 is configured in the embodiment shown as a bolt. Alternatively, the twist shuttle 65 may also be configured in a T-shape, whereby the twist shuttle 65 may also be used as a support device (not shown). The lift cylinders are typically equipped with end position sensors that are also connected to a controller device 60 (see fig. 1). In this way it can be determined exactly whether the piston stroke has been carried out according to the program and whether all end positions are present or damped (run) according to the program.
The positioning device 70 also has a support device drive 87 for positioning the support device 85 from the support position to the rest position. The support device drive 87 has a linkage 89, on which the support device 85 is arranged. The support means 85 is movably connected to the link means 89 by a hinge 90, wherein a servo motor 91 for moving the link means 89 is provided. The support device 85 can be moved from the rest position into the support position by a pivoting movement (see fig. 4 and 5) or can be moved from the support position into the rest position by a pivoting movement (see fig. 6 and 7). The support means 85 is designed as a bolt which rests against one side of the cable 16 and supports the cable 16 from this side.
The twist shuttle drive 72 and the support device drive 87 are driven by a servo motor 91. Alternatively, electric, pneumatic or hydraulic actuators may be used. In addition, both the twist shuttle drive 72 and the support device drive 87 may be driven by their own servo motors (not shown).
The twisting apparatus 15 has a first sensor device 66 for detecting the position of the twist shuttle 65 and a second sensor device 82 for detecting the position of the support device 85. The first sensor arrangement 66 and the second sensor arrangement 82 are connected to the controller arrangement 60 of the twisting apparatus 15 for exchanging sensor data (see fig. 1).
The first sensor device 66 is disposed on the twist shuttle drive 72. The twist shuttle drive 72 is here equipped with a lifting cylinder 73 with an end position sensor. The respective end positions of the lifting cylinders are determined by means of end position sensors. Depending on the end position, the lift cylinder 73 is in a twisted or rest position. This position, i.e. the corresponding sensor data, can be transmitted to the controller device 60 of the twisting apparatus 15 (see fig. 1).
The second sensor device 82 is arranged on the support device driver 87. Here, the supporting device driver 87 is equipped with a servo motor 91, and the servo motor 91 has a resolver 92. By means of the resolver 92, the number of revolutions and the angular position on the servo motor shaft can be determined starting from the starting position. The data from the parser 92 may be communicated to the controller device 60 of the twist apparatus 15. The sensor data may also include position data or positioning data for the support device 85 and/or the twist shuttle 65. For example, the coordinate data of the support device 85 and/or the twist shuttle 65 in the coordinate system of the twisting apparatus 15 is detected by the sensor device 66 or 82 or 110 and transmitted to the controller device 60 of the twisting apparatus 15 (see fig. 1).
Alternatively, a light barrier, a distance sensor or a lift cylinder with an end position sensor can also be used as sensor device 66 or 82 or 110, which is likewise connected to controller device 60 for exchanging sensor data.
Fig. 8 shows the twist head adding apparatus 20 of the twisting device 15 in a rear view in the cross-sectional view C-C of fig. 2. In the following description of fig. 8, reference is also made to fig. 1 to 3, in particular to the components referenced 26, 40, 41, 56, 80, 10, 95-97.
The twisting head device 20 comprises a twisting rotor 22 and a twisting rotor drive 21. The twisting rotor driving device 21 drives the twisting rotor 22. The twisting head device 20 has a first gripper device 30 and a second gripper device 45. Gripper devices 30 and 45 are rotatably disposed on twisting rotor 22, respectively, and are driven by gripper drive device 55. The first gripper arrangement 30 has a first gripper shaft 31 and the second gripper arrangement 45 has a second gripper shaft 46.
The gripper driving means 55 and the twisting rotor driving means 21 are arranged on a common fixture 54, and the gripper driving means 55 and the twisting rotor driving means 21 are electrically connected to a controller means 60 (not shown) of the twisting means 15.
A twisting rotor 22 may be rotatably arranged on the twisting head arrangement 20 about a rotation axis 23. For driving the twisting rotor 22, the twisting rotor drive 21 has a servomotor 26 and a belt drive, which is designed as a timing belt drive 27.
The gripper drive 55 has its own servomotor 56 and its own belt drive to drive the two gripper shafts 31, 46. The belt drive is configured as a timing belt drive 57. Alternatively, another traction mechanism of the form-locking connection type, for example a chain or gear mechanism, can be used.
The servomotors 26, 56 comprise resolvers 40 or 41, respectively, the resolvers 40 or 41 determining the respective number of revolutions and the respective angular position of the twisting rotor 22 or the first gripper arrangement 30 and the further gripper arrangement 45. Resolver data on the number of revolutions and the angular position of the twisting rotor 22 or the first gripper arrangement 30 and the further gripper arrangement 45 are sent as sensor data to the controller arrangement 60.
The twisted rotor 22 has a hollow rotor shaft 35. The twisted rotor 22 and the hollow rotor shaft 35 are formed in one piece. The twisting rotor 22 is rotated about the axis of rotation 23 via a toothed belt of a timing belt drive 27. The timing belt drive 27 transmits the rotational movement from the servomotor 26 to the rotatably mounted hollow rotor shaft 35. A drive shaft 24 for driving the two gripper devices 30 and 45 is arranged in the hollow rotor shaft 35. The drive shaft 24 is arranged coaxially with the hollow rotor shaft 35. Two bearings 25a and 25b, for example ball bearings, are arranged as drive shaft bearing 25 in the hollow rotor shaft 35. Therefore, the drive shaft 24 is rotatably supported with respect to the hollow rotor shaft 35 by the bearings 25a and 25 b.
Within the twist rotor 22 there is arranged a connecting shaft 36 which establishes an effective connection between the drive shaft 24 and the gripper shaft 31 and between the drive shaft 24 and the gripper shaft 46. The connecting shaft 36 is rotatably arranged and supported within the twisting rotor 22 by means of a connecting shaft support means 37. The connecting-shaft supporting means 37 includes a first bearing and another bearing (not shown).
The aforementioned operative connection is established by means of the first transmission 48 and the second transmission 49. A first transmission 48 is arranged between the drive shaft 24 and the connecting shaft 36. A second transmission 49 is arranged between the connecting shaft 36 and the first and second gripper shafts 31, 46.
The two transmissions 48 and 49 are in each case designed as timing belt transmissions 42 and 38, wherein alternative traction or gear transmissions of force-locking or form-locking type can also be used.
The two gripper shafts 31 and 46 are rotatably arranged on the twisting rotor 22 and extend into the twisting rotor 22, respectively. The two gripper shafts 31 and 46 have a first gripper rotation axis 32 and a second gripper rotation axis 47, which are radially spaced apart relative to the rotation axis 23 of the twisting rotor 22, respectively. The two gripper shafts 31 and 46 are arranged on pitch circles in the twisting rotor 22. The cable 16 clamped in the grippers 33 and 43 of the two gripper shafts 31, 46 rotates not only about its own gripper rotation axis 32 and 47 but also on a circular path about the rotation axis 23 of the twisting rotor 22. The first gripper shaft 31 and the further gripper shaft 46 are rotatably supported or arranged within the twisting rotor 22 by means of a gripper support 50. The gripper support 50 has at least a first and a second bearing for the first gripper shaft 31 and a first and a second bearing (not shown) for the further gripper shaft 46.
The first gripper device 30 has a gripper 33 for gripping a cable end of the cable 16, wherein the gripper 33 has an axially guided closing sleeve 44 for at least partially enclosing the gripper 33.
The further gripper device 45 has a gripper 43 for gripping the cable end of the cable 16, wherein the gripper 43 has a further closure sleeve 44 for at least partially enclosing the gripper 43, which is guided in the axial direction.
Fig. 9 shows a cross-sectional view B-B of fig. 8.
The twist rotor 22 is connected to and driven by a twist rotor drive 21 through a timing belt drive 27. The connecting shaft 36 is connected to the drive shaft 24 through a timing belt transmission 42, and the drive shaft 24 is in turn connected to a gripper drive 55 through a timing belt transmission 57 (see fig. 8). Here, the connecting shaft 36 is driven by the gripper drive 55 and its servomotor 56 and timing belt transmission 57. The first gripper shaft 31 and the further gripper shaft 46 are connected to the connecting shaft 36 by means of a further transmission 49 configured as a timing belt transmission 38, whereby the first gripper shaft 31 and the further gripper shaft 46 can be driven by means of a gripper drive 55.
A typical twisting process is described below.
To twist the cable or cable, the first cable end of the first cable 16 is clamped in the gripper 33 of the first gripper device 30. The second cable end of the first cable 16 is clamped in a clamping holder of a clamping device 28 (see fig. 1 to 9 in this respect).
Then, at least a first cable end of the further cable 16 is clamped into the gripper 43 of the further gripper device 45 and a second cable end of the further cable 16 is clamped into the clamping gripper of the clamping device 28.
Then, twisting rotor 22 is driven to rotate about rotation axis 23 of twisting rotor 22 by a first number of revolutions. Here, the twist rotor 22 is driven by a servomotor 26 of the twist rotor drive 21.
At the same time, the first gripper means 30 and the second gripper means 45 are driven in rotation about their respective gripper rotation axes 32 and 47 with a second number of revolutions, wherein this is done by means of the servomotor 56 of the gripper drive 55. The first number of revolutions and the second number of revolutions are predetermined by the controller means 60 of the twisting apparatus 15, the second number of revolutions being for example 60% to 70% of the first number of revolutions. The twisting rotor 22 and the two gripper arrangements 30 and 45 are driven in the same rotational direction. During twisting, the gripping device 28 moves along the guide rail 101 of the guide device 100 to compensate for the shortened length of the cable 16 during twisting. The movement is predetermined by the controller means 60. After twisting is completed, grippers 33 and 43 and the two clamping grippers of the two gripper assemblies 30 and 45 are released so that the twisted cable 16 can be removed from the twisting head assembly 20 and the clamping assembly 28, either by its own weight, to fall under the twisting head assembly 20 or to a collection trough arranged under the twisting head assembly 20.
To twist or twist at least two electrical and/or optical cables 16, the cables 16 are first picked up in pairs by two feeding devices 29 and 34 and the cables 16 are guided between the first twist head device 20 and the clamping device 28. The two cables 16 are then clamped in the twisting apparatus 15, wherein a first cable end of a first cable 16 is clamped in the gripper 33 of the first gripper device 30 and a first cable end of the other cable 16 is clamped in the gripper 43 of the gripper device 45. The second cable ends of the two cables 16 are clamped in the clamping device 28. The cables 16 are clamped parallel to each other in the twisting device 15.
Then, the position of the twist shuttle 65 is detected by the first sensor device 66 and the twist position or rest position of the twist shuttle 65 is determined.
A twisting process or twisting process is then performed at the at least two cables 16, wherein the twisting process is performed when the twisting shuttle 65 is in the twisted position and the twisting process is performed when the twisting shuttle 65 is in the rest position.
First, twist shuttle 65 is in a rest position, wherein twist shuttle 65 is out of the two cables 16 and thus remains unused during subsequent twisting. For example, the twisted shuttle 65 is in the locked position in this case. In the locked position, the twist shuttle 65 is arranged at the outermost position of the guide rail 19.
During the twisting process, the two gripper shafts 31 and 46 and the cable 16 clamped in the grippers 33 and 43 are driven to rotate by a servomotor 56 of a gripper drive 55, respectively.
At the same time, twisting rotor 22 is rotated about rotational axis 23 by means of hollow rotor shaft 35 of servomotor 26 of twisting rotor drive 21.
Gripper shafts 31 and 46 are arranged on pitch circles in twisting rotor 22. The cable 16 clamped in the grippers 33 and 43 of the two gripper shafts 31 and 46 then rotates not only about its own gripper rotation axis 32, 47 but also about the rotation axis 23 of the twisting rotor 22 and thus about its circular path. In this case, the cables 16 are wound around each other and additionally rotate about their own gripper rotation axes 32 and 47. (e.g., the clamped ends of the cables 16 may be on the pitch circle of the twisting rotor 22 and thus also maintain their angular position relative to each other as compared to the clamped cable ends in the clamping device 28).
The support device 85 may be used to support the cable 16 to be twisted during the twisting process. Here, before the twisting process is carried out, the position of the support device 85 is detected by the second sensor device 82 and the support device 85 is pivoted from the rest position into the support position. The support device 85 then rests against the side of the cable 16 to be twisted and supports the cable 16 so that the cable 16 does not sag or slacken. If necessary, during the twisting process, the support device 85 is moved or positioned along the guide 19 or the cable 16 to be twisted by means of the positioning device 70 from a first support position to another support position. Here, the support position is determined by the controller device 60 of the twisting apparatus 15. The support device 85 is here moved along the guide device 18 from the clamping device 28 to the first twist head device 20. Furthermore, the position of the support means 85 along the guide means 18 is determined at least by the sensor means 82, and the sensor data is transmitted to the controller means 60. In the controller device 60, the sensor data are further processed into data recording or movement commands and stored in a memory device 61.
After the twisting process, the support 85 is pivoted into the rest position by means of the support drive 87, wherein this is triggered by the end of the twisting process. The twisted cable 16 is then released from the twisting apparatus 15 and falls into a collection trough (not shown).
A typical stranding process is described below.
Here, in the configuration of the twisting apparatus 15 described here, the twisting process is started on the side of the clamping device 28 due to the system arrangement.
When twisting from one side (side I) of the clamping device 28 towards the first twisting head device 20 (side II), the first twisting head device 20 operates in a twisting mode. The servomotor 56 of the gripper drive 55 drives the first gripper shaft 31 and the further gripper shaft 46 via the drive shaft 24 and via the connecting shaft 36 by means of the timing belt drive 38 or 42 or 57, respectively, about the respective gripper rotation axes 32 and 47. The servomotor 26 of the twist rotor drive 21 is connected to the hollow rotor shaft 35 via a timing belt transmission 27.
The cable 16 to be stranded is clamped in a clamping device 28 in a clamping holder. The opposite ends of the cable 16 are clamped in the grippers 33 and 43 of the twisting rotor 22 of the twisting head device 20. A suitable pulling force is applied to the cable 16 to be stranded in the axial direction. This pulling force is due to the positioning of the movable clamp arrangement 28 at a distance from the wringing head arrangement 20 that is stored by the controller arrangement 60.
The twisting shuttle 65, which can be moved in the longitudinal direction on the positioning device 70, is lowered from above between the clamped cables 16 in front of the clamping device 28 by means of a linear movement, and the support device 85 is pneumatically pivoted to support the cables 16 below the cables 16.
During twisting (also referred to as twisting function mode), the clamping rotor of the clamping device 28 rotates the cable end clamped in the clamping gripper.
The two gripper shafts 31 and 46 are rotated by means of a servomotor 56, so that the gripped cable ends rotate in parallel about their respective gripper rotation axes 32 and 47, respectively. The rotational speeds of the two gripper shafts 31 and 46 are programmed in accordance with the rotation of the clamping rotor of the clamping device. By means of this function, the cable to be stranded is released in the process either immediately or completely or to some extent in relation to the rotational tension, since the rotation of the grippers 31 or 46 can compensate for the autorotation of the respective cable 16 there. The hollow rotor shaft 35 of the first twist head device 20 is not rotated by the servomotor 26 in the function described here.
The twisting process starts before the clamping device 28, wherein the positioning device 70 with the twisting pin 65 and the support device 85 is moved towards the twisting head device 20, wherein the positioning device 70 with the twisting pin 65 and the support device 85 is moved away from the clamping rotor in each revolution of the clamping rotor by a distance of the same order of magnitude as the programmed twisting pitch. The movable twisting shuttle 65 predetermines a lay length to be generated. This process is repeated for all subsequent twist rotations. By varying the twist shuttle travel per revolution of the clamping rotor or by varying the distance of the twist shuttle 65 from the first position to the other position, the resulting lay length can be varied and the length of the bundle of wires can be made or varied according to the program.
As a result of the twisting process, the overall length of the initially parallel arranged cables 16 decreases with each twist up to the twisted bundles (so-called twisted pairs). The pulling force exerted on the cable 16 in the axial direction during twisting is adjusted, wherein the servomotor 111 moves the gripping means 28 in a controlled manner according to a program, so that length compensation takes place. The stranding process is completed when the cables are stranded or intertwined with a programmed rotation and lay length. The movable positioning device 70 with the twist shuttle 65 and the support device 85 is positioned on the side of the twist head assembly 20 of the twisting apparatus 15 and then moved back to the starting position in front of the clamping device 28. The grippers 33 and 43 on the gripper shafts 31 and 46 and the gripping grippers of the gripping device 28 are opened and the stranded strands fall from the grippers into a collection or receiving groove.
During the twisting process (also referred to as the "twist function" mode), gripper shafts 31 and 46, respectively, which grip cable 16, are separately rotated by servo motor 56. In addition, the rotor hollow shaft 35 of the first twist head device and the clamping rotor of the clamping device 28 rotate. Gripper shafts 31 and 46 are arranged on pitch circles in twisting rotor 22. The cables 16 clamped in grippers 33 and 43 of gripper shafts 31 and 46 are then not only rotated about their own axis, but also rotated about the axis of rotation 23 of twisting rotor 22 on their circular path, wherein their angular position on the circular path and thus relative to each other is generally maintained. The twisting rotor 22 and the clamping rotor of the clamping device 28 are rotated in opposite directions to effect twisting. Where the cables 16 are twisted or twisted around each other.
During twisting, the longitudinally movable twist shuttle 65 for achieving the lay length is not engaged between the cables 16 to be twisted.
During the twisting process, the cable 16 to be twisted is clamped with the two cable ends side by side in the grippers 33 and 43 by means of the closing sleeve 44 and twisted with one another, for example in a helical fashion, according to the procedure. Here, the cable 16 to be twisted is also rotated about its own axis according to the system to cause the cable 16 to generate an internal tension, which must first be over-twisted and then be reversely twisted so that the strand having the desired lay length is brought into a state free from the influence of the tension with respect to the outside. For example, a reverse twist of about 30% to 40% of the previous twist turns is required to achieve the desired lay length. In addition to the processing time for over-twisting, the reverse twist time is also increased. The twisted wire harness drops into the collecting or receiving groove after opening all the grippers.
Furthermore, the twisting device 15 present here has a further support device 95 for supporting at least one cable 16. The further supporting means 95 is movably arranged on the further positioning means 80 and can be pivoted into a supporting position against the cable 16 and into a rest position of the cable 16. A further positioning device 80 is movably arranged on the guide 18 of the twisting apparatus 15. The further positioning device 80 and the further support device 95 arranged thereon can be moved in the direction between the clamping device 28 and the first twisting head device 20.
The further positioning device 80 has drive means, such as a servo motor 81, for moving the further positioning device 80 on the first guide 18, and the further positioning device 80 is connected to the controller means 60 of the twisting apparatus 15. Thus, the further support device 95 may be automatically moved between the first twist head device 20 and the clamping device 28. The further positioning device 80 has a separate support device drive 97, for example a servomotor or a lifting cylinder with a resolver, whereby the further support device drive 95 can be pivoted into a support position at the cable 16 and into a rest position of the cable 16. The support means driver 97 is connected to the controller means 60 of the twisting apparatus 15.
The twisting device 15 has a third sensor arrangement 96 which is designed to detect the position of the further support arrangement 95. The third sensor device 96 is connected to the controller device 60 for exchanging sensor data. These sensor data include, but are not limited to, data records relating to positioning information, position information or status information of the other support device 96.
If a twisting process is to be performed, the twisting shuttle 65 is moved to a twisting position between the two clamped cables 16 prior to performing the twisting process. For this purpose, the lifting cylinder 73 of the twisting shuttle drive 72 is actuated by the controller device 60 and the twisting shuttle 65, which is designed as a bolt, is moved between the two cables 16 to be twisted.
Subsequently, the position of the support means 85 is detected by the second sensor means 82, and the support means 85 is pivoted from the rest position to the support position.
The twisting shuttle 65 and the support device 85 are positioned in front of the clamping device 28 by means of the positioning device 70.
Subsequently, the two gripper jaws of the gripper device 28 are rotated by means of the gripper drive or its servomotor.
At the same time, the twisting rotor 22 of the twisting head device 20 rotates.
During twisting, the twisting shuttle 65 and the support device 85 are moved by means of the positioning device 70 in a direction from the clamping device 28 to the first twisting head device 20. Here, the position of the twist shuttle 65 is determined by a sensor device 66, and the sensor data is transmitted to the controller device 60 of the twisting apparatus 15. The sensor data is then further processed by the controller device 60 and stored in the memory device 62. The movement of the twisting shuttle 65 from the first position to the other position thus defines the lay length or number of wires of the cable 16 to be twisted.
The twisting shuttle 65 and the support device 85 move to the first twisting head device 20 and after the twisting process to the rest position, wherein this is triggered by the end of the twisting process.
As shown in fig. 10, in an alternative embodiment, the twisting apparatus 215 has a second twisting head arrangement 240 in addition to the first twisting head arrangement 220, which is arranged on a base 217. Thus, the second twisting head device 240 replaces the clamping device 28 of the twisting apparatus 15 (see fig. 1). The two wringer head assemblies 220 and 240 have the same configuration and are configured as described herein (see, e.g., fig. 8). The first twisting head device 220 has a twisting rotor drive 222 for driving the rotor hollow shaft 235 and a gripper drive 255 for driving the first gripper shaft 231 and the second gripper shaft 246. The second twisting head device 240 has a twisting rotor drive 241 for driving the rotor hollow shaft 269 and a gripper drive 273 for driving the first gripper shaft 263 and the second gripper shaft 264. In this embodiment, stranding (described above or herein) of cables 216 may be achieved where stranding shuttle 265 and support device 285 move or travel from first twisting head device 220 to second twisting head device 240. In this embodiment, stranding of cable 216 may also be achieved where stranding shuttle 265 and support device 285 move from second twisting head device 240 to first twisting head device 220. The first twist head assembly 220 operates in a twisting mode and the second twist head assembly 240 operates in a stranding mode to relax the cables 216 to be stranded during stranding. The positioning device 270 is movably arranged on the guide 218. A twist shuttle 265 moving on a positioning device 270 defines a lay length.
The cables 216 to be twisted are clamped in the holders of the holder shafts 263 and 264 in the second twisting head arrangement 240, wherein the holders are first opened and then closed in the axial direction, for example by means of a closing sleeve operated by a compression spring.
Servomotors 226, 256 of first twist head assembly 220, servomotors 274, 275 of second twist head assembly 240, drives of twist shuttle 265 and support assembly 285, and drives of positioning assembly 270 are connected to controller assembly 260 of twisting apparatus 215 to exchange control commands. These (as described herein) drivers have sensor means that transmit sensor data to the controller means 260, which sensor data is processed in an operator means 261 and a memory means 262.
The ends of the cables 216 are clamped on both sides in the grippers of the first and second twist head assemblies 240. The gripper shafts 231 and 246 of the first twist head device 220 are driven by a servo motor 256. The gripper shaft is supported on the pitch circle in the hollow rotor shaft 235. The hollow rotor shaft 235 is rotated by the servo motor 226. The servomotor 256 of the gripper shafts 231 and 246 is adjusted in conjunction with the servomotor 226 of the hollow rotor shaft 235 in such a way that the angular position of the gripper shafts 231 and 246 in the pitch circle of the hollow rotor shaft 235 remains unchanged throughout its rotation relative to the hollow rotor shaft 235.
On the side of the second twist head assembly 240, the gripper shafts 263 and 264 are also rotated by the servomotor 274, so that the cable end 216 clamped on this side of the second twist head assembly 240 is rotated about its own axis, whereas on this side the hollow rotor shaft 269 is not rotated by the servomotor relative to the hollow rotor shaft 235 of the first twist head assembly 220.
The direction of rotation of all the rotations, i.e. the gripper shafts 231 and 246, the gripper shafts 263 and 264 and the hollow rotor shaft 235 of the first twist head device 220, is the same, whereby for example in the first case all the rotations mentioned are performed in a clockwise direction if viewed from the side of the first twist head device 220 along the cable 216 to be twisted.
The cable 216 to be stranded is subjected to an appropriate pulling force in the axial direction, which is generated by the positioning of the movable twisting head device 240 according to the program according to the length of the wire 216 to be stranded.
The second twist head assembly 240 operates in a twist mode. The drive shaft 224 or central shaft is driven by a servo motor via a timing belt drive. The drive shaft is also connected to the connecting shaft by a timing belt transmission. The connecting shaft is in turn connected to two gripper shafts 263 and 264 by means of a timing belt drive. In this way, the two gripper shafts 263 and 264 are driven or driven to rotate by the servo motor 274, respectively. The servo motor 275 of the twist rotor drive 241 of the second twist head assembly 240 is coupled to the rotor hollow shaft of the second twist head assembly 240 via a timing belt drive, but the rotor hollow shaft does not rotate in the function described herein.
The twisting should be done with a defined lay length. Twisting begins directly before the first twist head assembly 220 in the twisting direction described herein. The two cables 216 to be twisted are arranged parallel to each other. In front of the first twist head device 220, a twist shuttle 265, which is longitudinally movable on a positioning device 270, is arranged between the cables 216, which according to the program moves from the hollow rotor shaft 235 of the first twist head device 220 towards the second twist head device 240 in each revolution of the hollow rotor shaft 235 of the first twist head device 220 by a distance of the same order of magnitude as the desired lay length. The movable twisting shuttle 265 is located between the two cables 216 to be twisted, thus defining the resulting lay length. This process is repeated for all subsequent twist rotations. By varying the travel distance of the twisting shuttle, the resulting lay length may also be varied and made on the length of cable 216 to be twisted according to the program. A pivotable support means 285 is likewise arranged on the positioning means 270, which support means supports the cable 216 from below during the process.
As a result of the stranding process, the overall length of the cables 216, which are initially arranged in parallel, decreases with each stranding up to the stranded strands. The tension applied to the cable 216 in the axial direction during twisting is adjusted, wherein the driver 222 moves the second twisting head device 240 in a controlled manner according to a program, thereby performing length compensation. The stranding process is complete as the cables 216 are placed around each other with a programmed rotation and lay length. Movable twist shuttle 265 is located on one side of second twist head assembly 240 of twisting apparatus 215. The support 285 and twist shuttle 265 return to their rest positions. The grippers on the gripper shafts 231, 246 and 263, 264 are opened and the twisted strands drop from the grippers into a collection or receiving trough.
Thereafter, all elements may return to their first starting position and the twisting process may be restarted. It is also possible to perform the aforementioned twisting process in the opposite direction, wherein the second twisting head arrangement 240 operates in a twisting mode and the first twisting head arrangement 220 operates in a twisting mode. Here, the other two cables 216 are clamped in the twisting device 215 before the stranding process. The positioning device 270 is disposed in front of the second twisting head device 240 and moves toward the first twisting head device 220 along the guide 218 during twisting. The twist shuttle 265, which travels over the positioning device 270, again sets the lay length, and the support device 285 abuts the cable 216 and moves with the positioning device 270.
In performing the twisting or twisting described herein by the twisting apparatus 15 or 215, the controller device 60 or 260 of the twisting apparatus 15 or 215 determines and generates data recording and/or movement commands for controlling the twisting head devices 20 or 220 and 240, which performs the method for twisting or twisting at least two cables 16 or 216. The position of the twist shuttle 65 or 265 is detected by means of the first sensor device 66 and the position of the support device 85 or 285 is detected by means of the second sensor device 82 and at least one data record and/or at least one movement command is generated and stored, respectively. The respective at least one data recording and/or at least one movement command at least specifies the position of the twist shuttle 65 or 265 and/or the movement of the twist shuttle 65 or 265 from the rest position to the twist position and/or the position of the support device 85 or 285 and/or the movement of the support device 85 or 285 from the rest position to the support position. As previously described, the servomotor or the lift cylinder of the twist shuttle drive 65 or 265, of the support device 85 or 285 and if necessary of the further support device 95 are connected to the controller device 60 or 260. Further, the servo motors of the gripper driving device 55 or 255 and the twisting rotor driving device 21 or 221 of the first twisting head device 20 or 220, and the servo motors of the gripper driving device 273 and the twisting rotor driving device 241 of the second twisting head device 240 or the clamping device 28 are connected to the controller device 60 or 260. Thus, all sensor data is transmitted by the sensor device and by the servo motor or its resolver to the controller device 60 or 260 and corresponding data records and/or movement commands are generated. The data recording and/or movement commands are stored in the memory device 62 or 262 and can be transmitted to the controller device 60 or 260. The data recording and/or movement commands are converted into control commands in the controller device 60 or 260 and then stored in the memory device 62 or 262 and/or transferred to the drives of the twisting apparatus 15 or 215 present there for controlling these drives.
A method for twisting or stranding is thus achieved by the twisting device 15 or 215 here, which is carried out by a program (generally with automated software) which is executed in the arithmetic device 61 or 261 and which controls the twisting device 15 or 215 completely automatically.
Advantageously, the controller device 60 or 260 is connected to the network, so that the state of the twisting device 15 or 215 can also be detected in the network.
