Definitions

  • the invention relates to a twisting device for electrical lines, according to the preamble of claim 1, and a method therefor, according to the preamble of claim 13.
  • a method for twisting electrical or optical lines such as wires, cables, bundles of lines, optical fibers, etc.
  • the wires are successively drawn into the twisting device between the twisting heads, and during the twisting operation, the pitch of the twisting heads is reduced from each other, preferably in response to the turns of the twisting heads, to compensate for the total length shortening of the twisted wires during twisting.
  • Advantageous variants provide for gradually increasing the rotational speed of the twisting heads during a first portion of the twisting operation and for successively reducing them during a second portion of the twisting operation or for separately increasing and reducing the rotational speeds of the twisting heads or for programmable rotational speed profiles.
  • the DE19631770A1 a stranding machine in which prepared lines are manually clamped. The stranding of the two lines takes place by rotating the two lines starting from the cable ends clamped in the twisting head with simultaneous controlled movement of a drillship so that the distance between the drillship and the twisting head increases as the process progresses. In this process, the pipe sections that are located between the drillship and the twisting head are twisted.
  • the Verdrillspannagen are arranged movable by means of a feed device, such as a pneumatic cylinder with back pressure control, along the linear guides. This feed device with pneumatic cylinder and counter pressure control, mounted under the twisting head with the Verdrillspannagen moves the entire shortening path that arises during twisting.
  • the object of the present invention was therefore to design a twisting device such that the very dynamic and difficult to control due to disturbances such as material tolerances twisting process is easy to monitor that a process automation is possible with the same constant traction, with load peaks on the Lines can be avoided, and that a possibility for immediate quality control of the twisted lines is created.
  • Another object of the invention was a method for producing twisted lines with the advantages mentioned.
  • such a device is characterized in that the twisting head is seated on a first, automatically motor-driven length compensating slide, wherein the clamping device is mounted on a Wegaus somnsschlitten to a length compensating slide substantially parallel to the axis of rotation of the twisting head, via a force-generating element with a Acting essentially parallel to the axis of rotation force can be acted upon.
  • a further twisting head is seated on the path compensating slide as a clamping device, which is rotatable in opposite directions about an axis of rotation common to the first twisting head.
  • the path compensating slide is passively movable and is acted upon by a biasing element with a force away from the first twisting head. In this way, a tensile force is applied to the lines over the entire travel range of the elements moved during the twisting process, thereby improving the twisting process and its quality.
  • the biasing force of the biasing element is adjustable at least before the start of the activation of the drive of the length compensation slide and preferably remains constant during the twisting process. This way you can talk about the entire traversing range a constant tensile force when twisting be applied. Material-related tolerances are compensated during the twisting by the axially movable clamping device according to the constant tensile force adapts their axial holding position.
  • the biasing element is connected via a controllable pressure control valve to a pressure source fluid cylinder, preferably a pneumatic cylinder according to an advantageous embodiment.
  • the piston rod of the fluid cylinder or the path compensation slide is provided or coupled with a distance measuring sensor which is connected to an evaluation device for determining and evaluating the travel profile of the force compensation slide.
  • the position of the piston rod or the carriage can be monitored, which corresponds to the holding position of the clamping device. Due to the small axial movements of the clamping device during the twisting process, which are typically in the range of 40mm, so that the twisting process within the "normal" tolerances is well monitored. Faults and faults outside of this normal twisting process will cause the monitoring tolerance tube to leave. This quality control of the twisting process can be realized.
  • Wegmesssensors also initiators are conceivable, which are damped as long as the carriage is moved in the allowable monitoring tolerance hose.
  • the force balance slide with a force measuring sensor and a motor drive can be equipped as a force-generating element.
  • the power compensation slide is acted upon in dependence on the signals of the force measuring sensor by the drive at least during the twisting operation with a direction away from the first twisting head and possibly variable force.
  • the driving profile of the clamping device can also be used in this case - but now actively prescribable.
  • a drive for the length compensating slide can be activated via a programmable controller in order to drive off a travel profile predetermined for each line, line type and / or twisting parameter predominantly in the direction of the clamping device, and the maximum possible travel path the Wegaus somnsschlittens by preferably adjustable stops is kept smaller than the maximum travel of the length compensation slide. Due to the twisting process, the length of the twisted wire is shortened depending on the twisting rotations after a parabolic function. Variables in the twisting process are e.g.
  • At least the drive of the length compensating slide is connected to a control unit in which for each combination of lines and Verdrillparametern a driving profile for controlling the drive of the length compensation slide is stored.
  • a sequence is implemented, which interrogates the evaluation and / or the Wegmesssensor and depending on the determined driving profile of Wegaus GmbHsschlittens generates a quality statement and / or adapted the driving profile of the length compensation slide, possibly as stored new driving profile for this combination of lines and Verdrillparametern in the control unit, and / or aborts the twisting operation with an error message.
  • the monitoring of the twisting process can also be used to automatically adjust the parameters of the twisting process.
  • a device is particularly advantageous which is characterized in that a sequence is implemented in the control unit, which controls the length compensation slide such that the values supplied by the Wegmesssensor lie in a predetermined range, and generates a quality statement depending on the determined driving profile of Wegaus GmbHsschlittens and / or the driving profile of the length compensating carriage adapted, possibly deposited as a new driving profile for this combination of lines and Verdrillparametern in the control unit, and / or the Verdrillvorgang aborts with an error message.
  • a further variant of the method according to the invention is characterized in that the twisting head moves away in a driving direction in the direction of the clamping device for each line type and / or twisting parameter, while the force caused by shortening the twisted lines counteracts the effect of a force-generating element the twisting head is shifted.
  • Quality monitoring of the twisting process is advantageously possible if the driving profile of the clamping device is evaluated during the twisting operation, whereby the exceeding of a predetermined limit for the travel path and the associated revolution is preferably monitored, so that a monitoring hose can be displayed which is at Demand requires a detailed assignment of the limit violation in association with the revolution.
  • a variant according to the invention can provide that the driving profile of the twisting head is adapted as a function of the driving profile of the clamping device, preferably for a predefinable number of twisting operations with similar lines and twisting parameters.
  • twisting device with compensation of the theoretical length reduction in the twisting process has a twisting 1 on.
  • a pair of wires 3 to be twisted is held by a second twisting head 5, wherein the two twisting heads 1, 5 can be rotated in the opposite sense about a common axis of rotation.
  • a non-rotary clamping device may also be provided.
  • the non-rotary clamping device can be provided as a variant and instead of the first twisting head 1, in which case the second twisting 5 is rotated.
  • the twisting of three or more lines is also conceivable if the twisting heads 1, 5 or the clamping device, in particular their clamping mechanisms, are designed accordingly.
  • the lines After passing the line pair 3 to the twisting heads 1, 5, the lines are initially arranged side by side in parallel and clamped at the ends in the grippers of the twisting heads 1, 5.
  • the twisting process starts, the two will Lines by the action of at least the twisting head 1 twisted around each other, wherein the axial tensile force should be constant during twisting. However, a variable tensile force depending on the progressive twisting process may also make sense.
  • the length of the twisted wire 3 between the twisting heads 1, 5 is shortened. Shortening takes place as a function of the twist rotations after a parabolic function.
  • the number of twist rotations required for the twist application is approximately equal to the length of the twisted pipe 3 (plot / job) divided by lay length. In addition, for example, about 40% of overdrive must be expected, which then have to be drilled back.
  • the length reduction in the twisting process can be described mathematically using the variables in the twisting process (eg line diameter, line material, line length, number of twist rotations (forward and backwards for decompression), traction during twisting and twisting length to be achieved as twisting result, etc.) ,
  • the parameters of the twisting process for a specific configuration of these variables can be saved as a file (so-called "recipe").
  • the basic data for these formulations are initially determined in preliminary tests for each line cross-section. Once basic data has been determined, the data for other line lengths can be derived mathematically.
  • the theoretical length reduction is implemented in the twisting process by the first twisting head 1 sitting on a length compensating slide 2, which can be actively moved by a programmable servo drive according to the required recipe during twisting and preferably according to the Verdrillumwinditch and thus the shortening of the lines to be twisted third compensated during the twisting process.
  • the axial tensile force in the cable pair 3 to be twisted would have to remain substantially constant, as is desirable for most twisting processes.
  • a variable traction force profile could also be programmed via the twisting.
  • a biasing element for example, a pneumatic cylinder 6 are used, a working space with adjustable and independent of the piston position constant pressure is applied.
  • a defined tensile force for example, over the entire travel range of both carriages 2, 4 are applied to the twisted pair of wires 3 during twisting.
  • the pneumatic pressure to supply the cylinder 6 is - as in Fig. 4 shown in an exemplary pneumatic circuit diagram is set by means of a programmable pressure control valve, preferably a 5/2-way valve 44 by user interface.
  • the pneumatic system comprises in total the compressed-air source 41, an electropneumatic regulator 43 inserted between the latter and the compressed-air accumulator 42, as well as two mufflers 47 at the outlet openings of the valve 44.
  • a stopper 45 closes a path of the valve 44 parallel to the cylinder 6.
  • the pneumatic cylinder 6 becomes supplied with the pneumatic pressure on one side, so that the existing on the piston rod traction over the entire travel range of the piston is constant. Material-related tolerances are compensated during the twisting by the now axially movable twisting head 2 according to the constant tensile force adapts its axial holding position.
  • the twist reduction to be compensated for by tolerances requires only a relatively short travel of the path compensating slide 4 mounted below the twisting head 5, in particular in comparison to the travel of the length compensating slide 2 for the first twisting head 1, typically in the range of approximately 40 mm. This is also by comparing the FIGS. 2 and 3 to recognize. If the position of the piston rod, of the carriage 4 or of the twisting head 5, ie the twisting head holding position, is monitored by means of a displacement sensor 7, the twisting process can thus be monitored well within the "normal" tolerances. Faults and faults outside of this normal twisting process will cause the monitoring tolerance tube to leave. This can be detected, processed and displayed by an evaluation unit.
  • the twisting process is thus divided into two movements.
  • the line 3 After the line 3 has been loosely clamped in both twist heads 1, 5, the line 3 is servomotorically brought to tension immediately or after a loose initial twisting with the length compensation until the twisting 5 or another, the twisting head 1 opposite jig about the middle of the possible Traversing the Wegausreteschlittens has reached.
  • the pneumatic cylinder 6 acts on the line 3 now with the set force constant.
  • the twisting is started and traversed by the length compensation of the twisting head 1 with a predetermined driving profile, wherein the twisting head 1 performs a computationally determined compensation ride to simulate the shortening of the lines to be twisted 3.
  • the second clamping device in this case the second twisting head 5, drives against the first twisting head 1 (it can also move away from the twisting head 1 under certain conditions), the travel distance being dependent on the force preset on the biasing element 6 for tensioning the lines 3 while twisting.
  • the twisting head 5 or the path compensating slide 4 supporting it only compensates small deviations from the ideal, programmed shortening of the cable.
  • a displacement sensor 7 or any other signal generator in conjunction with the second twisting 5 determines its driving profile during a twist and in an evaluation unit, the deviation of the line shortening is determined.
  • the driving profile of the twisting head 5 is recorded and evaluated via the twisting of the line 3. A faulty twist can thus be detected over the entire course, even a statistical evaluation is possible
  • the driving profile of the length compensation of twisting head 1, taking into account the balancing path of twisting 5 in the course of the first twists for similar lines 3 or similar Verdrillparameter is gradually adjusted.
  • a variant of the invention provides that the path compensating slide 4 or any arrangement having the same effect enables automatic determination of the driving profile for the first twisting head 1.
  • the driving profile typically follows a parabolic function. If the actual values for the initial range of the parabola are known, the complete parabola can be calculated from this.
  • two alternatively three or more to be twisted lines 3 are cut to length and clamped between the twist heads 1, 5.
  • the line length is predetermined, preferably via a graphical user interface, so that the length compensation slide 2 can be positioned.
  • the desired tensile force on the lines 3 is then adjusted to the pressure control valve 44 of the path compensation slide 4. Typical values are around 50N. Thereafter, the carriage 1 is moved back far enough that the carriage 4 of the twisting head 5 is pulled by the clamped lines 3 in the pneumatically controlled travel range.
  • the twisting operation is started at a slow speed of the twisting head 1 or the twisting heads 1, 5 and carried out until the carriage 4 has reached its Verfahrdorfde.
  • the travel path in association with the revolutions is detected via the distance measuring sensor 7 of the carriage 4.
  • the actual data for the beginning of the driving profile parabola are recorded.
  • the parabola can be calculated including the continuing driving profile.
  • the driving profile for the twisting head 1 and the length compensation slide 2 is programmable.
  • the calculated driving profile is based on a relatively small number of actual data, so that the deviations of all other twisting operations must be corrected if necessary.
  • the necessary corrections can be determined by means of the path sensor 7 of the path compensation slide 4 and used for the correction of the driving profile parabola.
  • a further advantageous application of the invention is to use the path compensating slide 4 for automated comparative measurement of the actual lengths of the two or more individually sequentially cut individual lines 3 in order to ensure the same length in the twisting region for both or more lines 3 to be twisted.
  • the length compensating slide 2 is moved away from the opposite clamping device until the line 3 is tightened is and continues the path compensation slide 4 is moved and thus its set tensile force acts axially on the single line 3.
  • the length compensation carriage 2 is then moved further to a defined reference point of the carriage 4, which is determined as a reference point by means of a value of the displacement sensor 7 or a fixed signal generator.
  • the waypoint of the length compensation carriage 2 reached at this point (determined from the resolver data of its servomotor) is then stored.
  • the length compensation slide 2 is then returned to its original position, wherein the tensile force acting on the line 3 is reduced again to zero and the path compensating slide 4 moves back to its starting position and the measured line can be removed or ejected from the twisting heads 1, 5.
