Description

TECHNICAL AREA

The present disclosure relates to a device for twisting a first and second electrical single line to a pair of wires, and a method of twisting a first and second electrical single line to a pair of wires using a device described herein.

STATE OF THE ART

In certain applications, two single electrical lines routed side by side are twisted into cable processing devices. After twisting, the cables form a (twisted) cable pair, which are routed into connector housings, for example, in a subsequent work step.

The EP 1 032 095 B1 shows a conventional cable processing device with a twisting machine. Two individual electrical cables are pulled in and assembled at the same time. Fabrication typically involves the individual leads being cut to length, stripped and / or provided with contacts, grommets, etc. at at least one of their ends. The individual cables are removed after the prefabricated cable ends have been assembled; the trailing cable ends are assembled; and then the lines are handed over to the actual twisting device. This has a stationary holding module, which holds the trailing cable ends during twisting, as well as a movable in the cable direction twisting head, which engages the leading cable ends and twisted together (twisted). During twisting, the pair of wires shortens due to the mutual wrapping of the Individual lines. A tensile force is measured, and the twisting head is tracked according to the measured tensile force, whereby the shortening is taken into account.

The EP 3 012 841 A1 describes a device for feeding cable ends to a further processing device. Here conductors are kept at a small distance from each other and twisted. A single pair of gripper jaws holds both ends of the line.

PROBLEMS TO BE SOLVED WITH THE REVELATION

The from the EP 3 012 841 A1 known approach makes it difficult to transfer tensile forces that occur during twisting on the individual lines. A clamping force that applies the pair of gripper jaws on the individual lines, can only be increased conditionally to ensure a secure fit without the individual lines are damaged, for example, deformed, resulting in a reduction in the quality of the line pair result.

It is an object of the present disclosure to provide an apparatus or method for twisting a first and second single electrical line to a pair of lines that ensures high quality of the twisted pair of lines.

SOLUTION OF PROBLEMS

According to the present disclosure, an apparatus for twisting a first and second electrical single line to a pair of leads according to claim 1 is given.

According to one aspect, the device comprises a main twisting device and a post-twisting device with a stationary post-twisting module and a post-twisting module that can be moved along a linear guide direction. Each of the post-twist modules comprises one each A transfer unit for receiving and holding one end of the twisted pair, the transfer unit comprising a first line conductor for the first single line and a second line line for the second single line, wherein a relative distance between the first line gripper and the second line gripper corresponding to a distance of the ends of the lines is changeable. At least one of stationary post-twisting module and portable post-twisting module is configured to post-twist the respective held pair of wires.

"Post-twisting", "post-twisting device", etc. designate here aspects that are temporally subordinate to a main twisting sub-process in the course of a total twisting process for a line pair. A Hauptverdrillprozess takes place, for example, analogous to that in the EP 1 032 095 B1 described twisting process. Following the main twisting process, the individual wires in the pair of wires are in an intertwined state over much of the expansion of the pair of wires. However, the pair of lines at the respective ends of the line (typically both at the leading line ends and at the trailing line ends) are further spaced apart.

According to the present disclosure, the transfer unit accepts and holds one end of the twisted pair of wires. The first line gripper of the transfer unit holds the first single line, and the second line gripper holds the second single line. The distance between the first line gripper and the second line gripper is variable, according to the distance of the ends of the individual lines. In general, the distance between the first line gripper and the second line gripper is reduced, so that the distance between the ends of the individual lines is also correspondingly lower.

Subsequently, the reduced in the spaced ends of the individual lines are twisted. The twisted ends of the Wires in the twisted pair of wires have a smaller distance at the end of the post-twisting with high quality.

Typically, the distance between the first line gripper and the second line gripper is programmably variable. Programmable modification includes, for example, adjusting the distance between the first line gripper and the second line gripper according to a predetermined or predeterminable line configuration (specification of a distance of a first intersection position, lay length of the twist, etc.) and / or according to a line condition (line cross section, thickness of the insulation, etc .).

In embodiments, the first lead gripper and / or the second lead gripper are configured to fix the respective held single lead. Alternatively, at least one of fixed post-twisting module and portable post-twisting module includes a fixing device configured to fix the respective held single line. Fixing, as used herein, includes gripping for preparing and / or performing the post-twisting operation.

In embodiments, at least one of stationary post-blending module and portable post-twisting module comprises a post-twisting head. Each post-twisting head holds the two individual wires of the twisted pair of wires and executes a predetermined or specifiable, typically programmable, number of revolutions for post-twisting.

In embodiments, at least one of the Nachverdrillköpfe is movable in the direction of the line pair, so that a tensile force is applied to the pair of wires. With the application of a tensile force line parameters such. B. the lay length are guaranteed even for the post-twisted line section at the end of the line. The at least one of Nachverdrillköpfe can be designed to be movable under power, to apply a predetermined or predetermined tensile force on the pair of wires.

In embodiments, the portable Nachverdrillmodul is designed as a carriage which is provided on a linear guide of the device and guided along the linear guide in the linear guide direction is movable. An execution as a linearly guided car allows a particularly simple and effective construction. The carriage can be moved by means of a toothed belt drive, which simplifies the structure again.

In embodiments, the portable post-twist module further comprises a drive for moving a respective held end of the lines in the conduit direction. The drive is typically designed as a spindle drive.

In embodiments, the transfer unit further comprises a horizontal drive and a vertical drive, wherein the horizontal drive and the vertical drive are configured so that they move at least one of first and second line gripper in a plane perpendicular to the cable axis perpendicular and horizontal. For example, the horizontal drive is a horizontal spindle drive. For example, the vertical drive is a vertical spindle drive.

According to another aspect, there is provided a method of twisting a first and second single electrical line to a pair of lines using a device described herein. The method includes twisting the single electrical leads to the main twisting module to obtain a twisted pair of leads; moving the line grippers of the transfer module to a position corresponding to an associated single line of the twisted pair cable; a transfer of the individual lines to the respective associated line gripper; reducing the distance between the line grippers; bringing the twisted pair of wires to a post-twisting position; passing the twisted pair of wires to the post-twist heads of the post-twist modules; and a post-twisting of the twisted pair of wires.

The method can automate a post-twisting operation with reduced spacing between the individual wires at the ends of the wire pair. For example, the distance of the individual lines at one or both ends of the line pair can be predetermined via a user interface. It is also conceivable that a distance of a first crossing position of the individual lines at the respective end to the line end can be predetermined. The first crossing position of the individual lines is the position, starting from the respectively considered end, at which the lines for forming the twisted state first abut each other or cross each other.

In embodiments, in the post-twisting, the twisted wire pair is fixed by one of the wire grippers or by a fixing gripper. This ensures a particularly simple and secure Nachverdrillen.

In embodiments, before moving the twisted pair of wires to the post-twisting position, the portable post-twisting module is moved toward the stationary post-twisting module. The pair of wires is thus relaxed before moving. A relaxation of the line pair reduces the risk that the held individual lines from the line grippers to solve or changed their position.

In embodiments, before the post-twisting of the twisted pair of wires and during the post-twisting, a tensile force is exerted on the pair of wires to be twisted.

DESCRIPTION OF EMBODIMENTS

Fig. 1 shows a twisted pair of wires 10 from a first single wire 11 and a second single wire 12. One end 16 of the wire pair 10 is defined as the leading end used in a twisting device 100 described later to be led. The other end 17 of the line pair is defined as a trailing end.

At the trailing end 17, a first contact 13 and a second contact 14 are attached to the lines 11 and 12, respectively. An area between the ends 16, 17 is twisted, d. H. the lines 11, 12 wrap around each other. Starting from the leading end 16 overlap or cross the lines 11, 12 for the first time in a first crossing point P2. Similarly, the lines 11, 12 intersect from the trailing end 17 for the first time in a first crossing point P1.

For explanation, a portion of the line pair 10 in Fig. 2 shown again. The untwisted ends of the individual lines 11, 12 at the trailing end of the line have a length a1. The distance between two similar crossings of the lines 11, 12 in the twisted region is specified as the lay length a2.

The distance a3 is defined in a direction substantially perpendicular to the running direction of the pair of wires 10 in which the distances a1, a2 are defined. The distance a3 indicates the distance of the individual lines 11, 12 at the respective end from each other, in Fig. 2 at the trailing end 17. A corresponding distance a3, which is equal to or different from the distance a3 at the trailing end, is also defined at the leading end 16.

Fig. 3 shows the subarea of the power pair 10 Fig. 2 , In Fig. 3 is the distance a3 between the individual lines 11, 12 opposite Fig. 2 reduced.

In Fig. 4 For illustration purposes, an apparatus 100 for twisting the individual electrical leads 11, 12 without a post-twisting device is shown.

In Fig. 4 the leading end 16 of the individual leads 11, 12 is led into a processing region 101, from where it continues can be guided on a guide rail 105 along a machine axis. Processing modules 103, 104, 105, 106 may perform manipulations on the lines 11, 12 in the processing region 101.

The leading ends of the individual lines 11, 12 are stripped of insulation by a cutting head 102 and fed successively with a first pivoting unit 107 processing modules 103, 104 on one side. Here, for example, a spout and a contact at the end of each conductor can be mounted.

Subsequently, the first pivoting unit 107 brings the pair of wires 10 back in the direction of the machine axis. There are the individual lines 11, 12 they passed so far until they can be grasped by an extension slide 109. The individual lines 11, 12 are pulled out depending on the desired line length of the extension slide 109 along along the guide rail 105 in the defined by the linear guide direction.

The individual lines 11, 12 are then gripped by a second pivot unit 108 and severed by the cutting head 102 and stripped. The trailing conductor ends are fed from the second pivoting unit 108 to the processing modules 105, 106 on the other side and finished, ie. H. For example, in turn, each provided with a spout and a contact.

A transfer module 111 takes over the trailing end 17 of the individual lines 11, 12, brings them to a smaller distance and transfers them to a holding module 110 after a pivoting movement. A transfer module 112 transfers the leading end 16 of the individual lines 11, 12 to a twisting head 120 Twisting head 120 is used in the device 100 according to Fig. 4 rotated, wherein it is simultaneously moved traction-controlled in the direction of the holding module 110. The twisting head 120 forms a main twisting device, with which, for example, the in Fig. 2 shown pair of wires having a comparatively large distance a3 between the individual lines 11, 12 at the respective ends 16 and 17, respectively.

In Fig. 5 the device 100 is off Fig. 4 shown in sections, wherein an after-twisting device 160 is additionally provided. The post-twisting device 160 comprises a stationary post-twisting module 170 and a portable post-twisting module 180. The portable post-twisting module 180 is movable along a linear guide provided separately on the guide rail 105, which defines the linear guide direction for the portable post-twisting module 180. The linear guide direction is parallel to the direction of movement of the twisting head 120 or of the pull-out slide 109.

Fig. 6 shows a portion of the device 100 in a view obliquely from below. In Fig. 6 For example, the holding module 110 and the twisting head 120 are shown. Instead of the holding module 110, it is also conceivable to provide a further twisting head in addition to the twisting head 120.

The stationary post-twisting module 170 has a post-twisting head 173 and a transfer unit 172. Correspondingly, the portable post-twisting module 180 has a post-twisting head 183 and a transfer unit 182. In the in Fig. 6 In the illustrated embodiment, the stationary post-twisting module 170 also has a fixing gripper 171. The portable Nachverdrillmodul 180 may correspondingly have a (not shown) fixing gripper.

The transfer units 172, 182 are configured such that they take over the pair of wires 10 twisted by means of the twisting head 120 and transfer them to the respective post-twisting head 173 or 183. The fixing grippers 171, 181, if provided, hold the pair of wires 10 during the Nachverdrillvorgangs.

The portable Nachverdrillmodul 180 is designed as a carriage that can be moved on the linear guide 105 by a (not shown) toothed belt drive. Thus, depending on the twisted cable, different end positions of the twisting 120 can be approached.

Fig. 7 shows a perspective view of the portable Nachverdrillmodul 180 from a first direction, Fig. 8 shows it from a second direction. The Nachverdrillkopf 183 can be moved with a Verdrillmotor 188 via a toothed belt drive. In addition, the post-twisting head 183 can be moved in the cable direction via a first spindle drive 189. The transfer unit 182 carries a first line gripper 184 and a second line gripper 185 which serve to grasp the ends of the individual lines 11, 12 located at a wide distance a3 from each other. One of the line grippers 183, 185 is attached to a linear axis, whereby the distance between the two line grippers can be programmably changed. The linear axis can be designed as a servo axis.

The transfer unit 182 has a horizontal spindle drive 186b and a vertical spindle drive 186a. The line grippers 184, 185 can thus be moved at right angles to the cable axis in a plane vertically and horizontally. To carry out these movements, other variants are conceivable in addition to the spindle drives with associated servomotors and guides, such. B. pistonless pneumatic cylinder.

Fig. 9 shows a perspective view of the stationary Nachverdrillmodul 170 from a first direction, Fig. 10 shows it from a second direction. The stationary post-twisting module 170 has the post-twisting head 173 and the transfer unit 172. This module does not need to be moved; Therefore, these components are not connected to each other and individually attached to the machine position. The post-twisting head 173 is similar to the Nachverdrillkopf 183 constructed and movable in the direction of the twisted pair of wires 10 by means of a pneumatic cylinder. The transfer unit 172 has a first line gripper 174 and a second line gripper 175, whose distance from a linear axis 177 is variable.

The pair of wires 10 may be fixed during post-twisting by a line gripper 174, 175 or by the separately provided fixing gripper 171.

The transfer unit 172 has three axes of movement: a horizontal belt drive 178 and a first vertical spindle drive 176a move the line grippers 174, 175 and the fixing gripper 171 together in a plane perpendicular to the axis of the line pair 10. A horizontal spindle drive 176b moves the line grippers 174, 175 alone parallel to the axis of the line pair 10.

The Fig. 11 to 19 each show the device 100 at different times when performing a method described herein. Parts (a) of Fig. 11 to 15 . 17 to 20 in the respective upper areas show a view with direction of a Verdrillachse V on a Nachverdrillachse; the parts (b) of Fig. 11 to 15 . 17 to 20 show in the respective lower areas a view from below. It is understood that the in Fig. 11 to 20 can be adjusted if only one of leading end 16 and trailing end 17 is to be post-twisted by merging the conductor ends and a post-twisting at the corresponding end are not performed.

In Fig. 11 the starting position is shown. In the following figures not provided with reference numerals components correspond to those in Fig. 11 ,

In Fig. 11 is a ready-made and twisted with the twisting 120 line pair 10 of a first electrical single line 11 and a second electrical single line 12 held in the holding module 110. The distance a3 between the first electrical single line 11 and the second electrical single line 12 is comparatively large. The line grippers 184, 185 of the portable Nachverdrillmoduls 180 and the line grippers 174, 175 of the stationary Nachverdrillmoduls 170 are in a waiting position above and between the Verdrillachse V and Nachverdrillachse N.

In the in Fig. 12 the first step shown, the two line gripper pairs 174, 175; 184, 185 move horizontally until they are above the respective cable ends. The line grippers 174, 175; 184, 185 can be moved sequentially or simultaneously in the cable direction to their respective positions.

In the in Fig. 13 the next step shown are the line gripper pairs 174, 175; 184, 185 lowered and are then at the height of the Verdrilachse V.

In the in Fig. 14 As shown, the distance of the line gripper 174 to the line gripper 175 or the distance of the line gripper 184 to the line gripper 185 is reduced and the line gripper pair 184, 185 moved slightly horizontally to grip the two line ends 11, 12. Then, the cable is passed to the line grippers 184, 185 and 174, 175, respectively, by connecting the two line gripper pairs 174, 175; 184, 185 are closed and then the cable gripper of the twisting head and the holding module 110 are opened.

As in Fig. 15 shown, after the transfer, the power ends 11, 12 brought to the desired distance for the Nachverdrillen. For this purpose, the distance between the respective line grippers 174 to 175 or 184 to 185 is further reduced by a further method of the respective linear axes.

Fig. 16 shows in (a) - (c) in each case an enlarged detail of the line grippers 184, 185 of the portable Nachverdrillmoduls 180, wherein (a) from an enlargement Fig. 13 represents, (b) an enlargement Fig. 14 represents and (c) an enlargement Fig. 15 represents. The line grippers 184, 185 are located in Fig. 16 in (a) - (c) each in different positions.

Fig. 17 indicates that Fig. 15 subsequent step. In Fig. 17 the line pair 10 is relaxed by the portable Nachverdrillmodul 180 is moved in the direction of the stationary Nachverdrillmoduls 170. The relaxation of the line pair 10 reduces the risk that the line ends during subsequent movement of the line pair 10 from the line grippers 174, 175; 184, 185 slide or be moved in it.

Subsequently, the two transfer units 172, 182 move the line pair 10 to the Nachverdrillachse N, wherein first at the stationary Nachverdrillmodul 170 a vertical movement is carried out so that it passes from the region of the open holding module 110. The two Nachverdrillköpfe 173, 183 are in an angular position, which allows the pair of wires 10 without collision in the open line gripper 174, 175; 184, 185 of Nachverdrillköpfe 173, 183 bring.

Fig. 18 shows the end position of the two transfer units. From here, the twisting head and the holding module are no longer shown in the figures.

Next, the pair of wires 10 are prepared for post-twisting. For this purpose, the line pair 10 is stretched again and grabbed by the Nachverdrillköpfen 173, 183. Thereafter, the line grippers 174, 175; 184, 185 open.

Before the post-twisting, both ends of the line pair 10 are fixed. In the case of the stationary post-twisting module 170, this takes over from the fixing gripper 171. After a positional correction of the transfer unit 172 in the horizontal direction of the fixing gripper 171 is closed, whereby the pair of wires 10 is gripped. In the case of the portable post-twisting module 180, the fixing takes place by one of the two line grippers 184, 185, which is correctly positioned by a horizontal movement of the transfer unit 182 in order to clamp the entire line pair 10 during closing.

Fig. 19 shows the situation immediately before the post-twisting. The line ends of the elongated line pair 10 are held in the two Nachverdrillköpfen 173, 183 and fixed the line pair 10 with the fixing gripper 171 and a line gripper 184, 185.

If necessary, a tensile force can be applied to the lines 11, 12 to be twisted.

The actual post-twisting is done by rotating the Nachverdrillköpfe 173, 183. For example, (not shown) machine control is provided, control of the known process parameters (lay length, outer diameter guide etc.) calculates a calculated number of revolutions for Nachverdrillköpfe 173, 183 and controls them accordingly.

Fig. 20 shows the device with the finished cable pair 10 with the two re-twisted cable ends 16, 17th

The fixation can be solved and the line pair 10 can be dropped after opening the Nachverdrillköpfe 173, 183, wherein the Nachverdrillköpfe 173, 183 are previously brought into the correct angular position. It is also conceivable first to open the post-twist heads 173, 183 and to move the cable through the transfer units 172, 182 before it is deposited.
