Definitions

  • the invention relates to a twisting device and a method for twisting electrical or optical lines, such as wires, cables, wire bundles, optical fibers, etc., with a base and a first, relative to the base rotatable twisting head, which is formed around the lines to be twisted to grab at their first ends.
  • electrical or optical lines such as wires, cables, wire bundles, optical fibers, etc.
  • Twisted lines are e.g. in vehicles, aircraft, etc., used to reduce as much as possible interference on and from other lines.
  • the twisted wires must meet specifications. You must have a defined uniform lay length over the total length and the insulation must not be damaged.
  • the average length of twisted wires in the automobile e.g. is about 4 meters.
  • Twisting machines are known inter alia from the following publications US6289944B1 .
  • EP1032095A3 DE10107670B4 .
  • EP0889486B1 and DE000019631770C2 are known inter alia from the following publications US6289944B1 .
  • DE 19631770 discloses a second head rotatable relative to the base for unthreading, the second head being rotatable in a directional sense to the first twisting head.
  • the disadvantage resulting from the known state of the art is in particular that the actual twisting process prevents temporal process optimization.
  • the speed of the twisting head is limited in terms of process reliability and the protection of the lines.
  • the aim of the invention is to eliminate this disadvantage and to provide a twisting device together with a method with which the duration of the actual twisting process can be substantially reduced.
  • the lines should be optimally protected.
  • the twisting process should therefore be gentle on the cable.
  • the cable insulation and the copper strands must not be damaged. A reliable and easy to program process flow should be guaranteed.
  • twisting head of the type mentioned above in that the twisting device has a second, relative to the base rotatable twisting head, which is arranged opposite to the first twisting head and is formed to the twisted wires at their second, the first ends opposite Grasping ends, and that the second twisting head is rotatable in the opposite sense to the first twisting head.
  • the twisting time is approximately halved.
  • the lines to be twisted are handled just as gently in the process as in twisting devices with only one-sided twisting drive.
  • the twisting heads are spaced from each other by approximately the length of the lines to be twisted. This distance is preferably variable in order, on the one hand, to be adaptable to different cable lengths and, on the other hand, to exert a predetermined tensile force on the lines to be twisted during the twisting operation.
  • the twisting heads are mounted on the base so that they have substantially the same axis as a rotation axis. When tensioned lines this axis coincides approximately with the longitudinal axes of the lines.
  • the common base may be a rack, a table, a suspension, a pedestal, a mounting platform, a rail and the like.
  • the lines are offset at both ends of lines of counter-rotating Verdrillköpfen in rotary motion about its longitudinal axis and twisted in this way in their total length with each other.
  • the twisted cable ends in the twisting head are not twisted.
  • the twisting heads preferably have their own drives.
  • the acceleration of the twisting head and thus the lines around the longitudinal axis is initially slow, so that the individual lines can form uniform wraps over the entire length with each other and are stabilized in the cohesion. Thereafter, the twisting process is further accelerated to the final speed, the lines being held in tension with a defined tensile force in the longitudinal direction.
  • the twisting takes place according to adjustable programs. First, a preselectable number of revolutions is twisted in one direction, then it is rotated back in the opposite direction of rotation, so that the finished twisted Line has no externally acting voltage. This is the case when the twisted, no longer clamped pipe remains stretched on a surface without bending, turning on its own axis or forming loops.
  • Twisting devices according to the known prior art have a twist drive at only one line end and a non-rotating line holder at the second line end.
  • the twisting process thus takes twice as long with the same number of revolutions with a twisting head, as with two counter-rotating twisting heads according to the invention (prerequisite: equal acceleration ramps and maximum speeds).
  • the lines are treated according to the invention gently.
  • there is an approximate halving of the twisting time with equally gentle twisting process in comparison to twisting devices with only one-sided twisting drive.
  • the twist heads each have a line transfer gripper assigned, which transfers the respective ends of the lines to the respective twisting head.
  • a line transfer gripper assigned, which transfers the respective ends of the lines to the respective twisting head.
  • each twisting head is rotated by a separate rotary drive.
  • each twisting head can be subjected to its own acceleration ramp as required.
  • the rotary drives of the twisting heads are synchronized with each other. With equal rotational speeds in the opposite direction of rotation, the twisting time can be maximally reduced, i. be halved.
  • the twisting heads are displaceable relative to each other for varying their mutual distance.
  • the Verdrillkée on own displacement drives.
  • the twist heads are adapted to different cable lengths.
  • This is a particularly simple and reliable way to vary the mutual distance of the twisting heads in the longitudinal direction.
  • the twisting device has a line pull-in gripper for gripping the lines and runs in the region between the twist heads a guide along which the line transfer gripper is movable to feed the lines in the region between the twist heads.
  • the base of the twisting device comprises at least two parts, wherein a second part of the base is movable relative to a first part of the base along a direction that is substantially parallel to the direction of travel of the line pull-in gripper along the guide, and wherein the guide the line intake gripper is seated on the first part of the base and one of the twisting heads is seated on the second part of the base, and that for positioning the second part of the base relative to the first part of the base of the line intake gripper can be coupled to the second part of the base, preferably via a Impact interface (which otherwise brings the lead-in gripper into an open and / or closed position) such that the coupled lead-in gripper, in a process along the guide, drives the second part of the base relative to the first part of the base and places it in the desired position.
  • a Impact interface which otherwise brings the lead-in gripper into an open and / or closed position
  • the distance between the twisting heads or between the line transfer grippers can be changed in a simple manner, for example, to adapt the twisting device to the length of the lines to be processed.
  • One of the twisting heads is thus moved programmably by the line intake gripper in its desired position.
  • This coupling function can save a complete positioning axis. The positioning takes over the line intake gripper whose control is already available anyway.
  • the active interface is designed to come into operative connection with the line pull-in gripper and bring it into a closed position or open position when the line pull-in gripper is in the effective range of the active interface.
  • the line pull-in gripper is thus preferably coupled via the same active interface to the movable part of the base, which is also used to open (or close) the line pull-in gripper.
  • the active interface comprises a gripper opener or -schliesser for opening (or closing) of the line intake gripper.
  • the Verdrillkexcellent each have at least two gripper arms, which can be brought from an open position into a closed, the lines cross-position.
  • the use of gripper arms has proven particularly advantageous.
  • Each twisting head thus also has a gripper drive for opening and closing the gripper.
  • twisting electrical or optical lines such as wires, cables, bundles of lines, optical fibers, etc.
  • a twisting device having a base and a first twisting head rotatable relative to the base, wherein the lines to be twisted reached at their first ends by the first twisting head reached.
  • the twisting device comprises a second, relative to the base rotatable twisting head, which is arranged opposite the first twisting head, wherein the lines to be twisted are gripped at their second, the first ends opposite ends by the second twisting head, and that the both twist heads are set in opposite directions in rotation.
  • the lines to be twisted are pulled one after the other into the twisting device between the twisting heads.
  • sequentially retracting the conveyor must be present only in one embodiment, which manufacturing costs can be reduced.
  • the respective ends of the lines are transferred by line transfer gripper to the respective twisting head.
  • the lines to be twisted are held by the line transfer grippers before being simultaneously transferred to the twist heads. This enables a particularly process-optimized procedure, since the line transfer grippers perform two functions. Temporarily hold the line (s) until all lines are retracted and transfer the lines to the twist heads.
  • the spacing of the twisting heads from one another during the twisting operation is reduced, preferably as a function of the rotational speed or the revolutions of the twisting heads and the resulting line wraps of the twisted pair of wires.
  • the total length of the wire pair (or wire bundle) reducing by twisting is compensated and a predetermined tension can be maintained.
  • twisting heads are driven synchronized with each other
  • the rotational speed of the twisting heads is successively increased during a first portion of the twisting operation.
  • the rotational speed of the twisting heads during a second portion of the Verdrillvorganges is successively reduced. This also represents a gentle treatment of the lines.
  • the direction of rotation of the twisting heads is reversed at the end of the twisting process in order to obtain a twisted pair of wires free of mechanical stresses.
  • the twisting device has a line pull-in gripper for gripping the lines and in the area between the twisting heads runs a guide, along which the line pull-in gripper is movable to draw the lines in the region between the twisting heads, and the base of the twisting device comprises at least two parts, wherein a second part of the base is movable relative to a first part of the base along a direction which is substantially parallel to the travel direction of the A line pull-in gripper stands along the guide, and wherein the guide is seated with the line puller gripper on the first part of the base and one of the twist heads is seated on the second part of the base, and that for positioning the second part of the base relative to the first part of the base of the line pull-in gripper the second part of the base is coupled, preferably via an active interface, and that the coupled line pull-in gripper is moved along the guide so that the second part of the base is driven relative to the first part of the base by the line pull-in gripper and brought into the desired position.

During the retraction of the lines 2, the line pull-in gripper 10 moves from left to right. If the first end of a line 2 has arrived in the area of the first twisting head 3, a line transfer gripper 6 takes over the first end of the line 2 and transfers it to the first twisting head 3. This grips the preferably consecutively drawn lines 2 at their first end and holds them during fixed the twisting process.
  • the second, the first end opposite the end of the line 2 is picked up in an analogous manner by a provided in the region of the second twisting 4 line transfer gripper 7 and passed to the second twisting 4.
  • Each twisting head 3, 4 has its own rotary drive 8, 9, with which the respective twisting head is set in rotation.
  • one of the twisting heads sits - in Fig. 1 this is the (right-hand) twisting head 3 - on a carriage 15 which is movable relative to the base 5 along the longitudinal direction (ie parallel to the axis of rotation of the twisting heads).

  • the carriage 15 is mounted on the movable second part 5b of the base 5 and relative to this longitudinally movable.
  • the twisting head 3 can successively follow the shortening of the twisting line. This adaptation of the twisting head to the changing cable length can be done by a separate displacement drive.
  • Fig. 2 shows in schematic and the function of the invention highlighting a twisting device 1 with the two twist heads 3, 4, in which two lines 2 are clamped.

  • this line 2 has already been equipped at its first, right end with a contact, for example by crimping.
  • the line pull-in gripper 10 detects the leading first line end (in the region of the active interface Z, which brings the line intake gripper 10 with a gripper closer in the closed, gripping position) and promotes the Line 2 synchronized with the line feeder (indicated by the arrow F only) of the basic machine to an active interface Y, which includes a gripper opener for opening the line intake gripper 10.
  • the line transfer gripper X takes over the first line end and the line intake gripper 10 returns open to take over the next line 2.
  • the trailing second line end is now also equipped with a contact, e.g. by crimping, and then transferred to the second line transfer gripper 7 with the aid of additional handling mechanisms.

  • both twist heads 3, 4 are programmed in opposite directions in rotation, accelerate until reaching the final speed and the preprogrammed number of revolutions. Then it is driven with a deceleration ramp. At the end of the twisting operation, the directions of rotation of both twisting heads 3, 4 are reversed, ie it is preprogrammed turned back in the opposite direction, so that the twisted pair of wires contains no outwardly acting voltages.
  • the lines 2 are acted upon in the axial direction with a defined tensile force, so that the desired Verdrilltex is achieved and on the other hand, the lines 2 are not damaged.
