Description

The invention relates to a gripper for electrical or optical lines, such as wires, cables, cable bundles, optical fiber, with at least one movable relative to an abutment means of a drive gripper jaw, wherein the drive assembly comprises at least one drive with adjustable force, via a link chain acting on the or each gripper jaw, further on a twisting head for twisting electrical or optical lines, such as wires, cables, cable bundles, optical fiber, with a rotatable about the axis of the lines gripper, wherein the drive is arranged stationary and the link chain at least one with having the twisting head with the rotating portion, as well as a twisting device for twisting electrical or optical lines, such as wires, cables, cable bundles, optical fibers, etc., with at least one rotatable by a second drive twisting head.

A gripper and a twisting device as described above is beispielswiese in the DE 10 107670 A1 disclosed. The twisting head used in this case has a number of clamping jaws corresponding to the number of individual lines, which can be acted upon by a predetermined clamping pressure in order to hold the line ends of the individual lines. The twisting head is rotatable about a Verdrillachse and movable in the longitudinal direction of the Verdrillachse. The twisting head has three jaws which are spaced apart from each other at a distance of 120 ° from each other about the axis of twisting. Each jaw consists of a lever arm, which is mounted pivotably about a pivot axis lying tangentially to the axis of rotation. The lever arm of a clamping jaw is pivotally connected to the gripper element for the lines opposite end with an intermediate part, which in turn is pivotally coupled to a sliding element, a double shaft joint and finally with a pneumatic cylinder. To open and close the gripping elements all the components mentioned in a Line are arranged one behind the other, also moved in the same direction. This arrangement builds very long and requires considerable over the actual length of the strands to be twisted size. Also, the components are relatively large and heavy, so that the arrangement for receiving the centrifugal forces during twisting must be very stable and therefore heavy construction. This also requires high drive and braking forces on the twisting head and thus stronger, more energy-intensive Verdrehantriebe and braking systems.

The DE 10 2010 017981 A1 discloses a device for merging conductors for producing a double crimp connection. The (double) grippers used therein have gripper arms that can be moved vertically to the gripper plane in a guide.

The EP 1 032 095 A1 refers to a processing and twisting of a conductor pair. In connection with a swivel unit, the grippers as a whole are individually pivotable via a lever mechanism. However, gripping the wire is not effected by the illustrated lever mechanism.

The EP 1 691 457 A1 discloses a de-twisting unit in connection with a cable processing device. A gripper is driven pneumatically (for example pneumatically closed and opened by spring force).

The US 4,272,951 A discloses a twisting device in which twisting is effected by a roller assembly comprising the wires to be twisted from two sides. These rollers or belt arrangement are rotatable. This is a completely different principle.

The US 5605181 A discloses a portable twisting tool wherein the wires to be twisted are clamped in the middle of their length by a device. At their ends are the wires by means Fixing devices fixed stationary. The twisting device consists of a sleeve with an elongate cutout into which a part is inserted, which sits on a second sleeve and projects between the two wires.

All known in the prior art solutions has in common that they are mechanically complex and have a high weight. Twisting devices are therefore very expensive and the drive requirement is high. Moreover, the holding force for line ends is not adjustable.

The object of the present invention is to provide a gripper, a twisting head and a twisting device, which does not have these disadvantages and which allows to automatically grasp two or more, optionally contacted line ends, secure and the lines at high speed into each other twist. In particular, the problem should be solved to realize the twisting with all automatisms, at the same time low mass of the twisting head and simple and inexpensive construction. The gripper mechanism should safely hold the lines independent of occurring centrifugal forces with an adjustable holding force without complex replacement or adaptation work.

The objects are achieved by the features of independent claim 1. Advantageous developments are set forth in the respective dependent claims.

The invention achieves this aim in a gripper according to claim 1 according to the invention in that the articulated chain has a portion parallel to the drive and with opposite direction of movement of the drive, which feature contributes to a compact arrangement of gripper and drive by parallel and close positioning. The ratio of driving force to holding force is precisely defined by the specified leverage ratios of the link chain. Thus, the holding force on the line by adjusting the Driving force, which is transmitted indirectly via the link chain with a precisely determinable manner on the jaws, precisely adjustable so that the optimal gripper closing force can be adjusted for the safe gripping and holding the line ends depending on line cross-section and line quality. The programmable value of the setting parameters can be assigned to the respective application and can be recalled at any time, which enables automatic setting up of the twisting process without manual setting up / setting up of components of the gripper or of the twisting head using this gripper. In particular, the drive power can be preselected by program, stored to manufacturing parameters suitable and recalled at any time. There are no energy or signal lines to the gripper, which is typically part of a rotating Verdrillkopfes required.

A preferred example of an adjustable force drive is a fluidic cylinder with programmable supply pressure. The supply pressure, for example, in a preferred embodiment of a pneumatic cylinder, and thus its driving force is programmable adjustable by a suitable controllable control valve. Thus, the holding force of the gripper jaws is precisely adjustable via the articulated chain with a precisely defined power transmission ratio.

Preferably, for the purpose of a good holding action and force direction, the direction of movement of the gripper jaws a predominant component radially with respect to the line, preferably, the direction of movement is exactly radial with respect to the line. A reference to "the line" here and throughout the text below is a designation that point of the device and the direction in which the intended use of the gripper or the device or parts of devices specified by this expression or in which direction this line is oriented.

An advantageous embodiment of a gripper according to the invention is further characterized in that the direction of action of the drive is predominantly parallel with respect to the line, wherein via the articulated chain a force deflection is provided in a direction of action in the direction of movement of the gripper jaws. With this feature, a very compact arrangement of gripper and drive is possible, which can thereby be positioned parallel and close to each other. For a twisting head, the object stated in the introduction is achieved by the features that the gripper designed according to one of the preceding paragraphs and the co-rotating portion of the link chain is formed by parallel to the drive and opposite to the direction of movement of the drive movable elements and by the or each gripper jaw, said the drive is arranged stationary and wherein the link chain has at least one co-rotating portion. These features ensure a compact, space-saving and safe construction of the twisting head. By deflecting the drive effect from the drive to the gripper by substantially 180 °, the drive and a long section of the articulated chain can be arranged in parallel. Such a parallel arrangement allows a short length of the arrangement. In addition to the design of the gripper as already explained above, the fixed drive contributes to a very simple, compact and lightweight construction of the twisting. The heavy drive does not have to be moved with the twisting head and / or the gripper, which also considerably simplifies its energy and operating resources supply.

Preferably, for a simple, compact and reliable construction in both variants of the twisting head provided that the articulated chain comprises a stationary lever, preferably a fork lever, via which the drive acts on the movable elements of the link chain, preferably with the interposition of an axial roller bearing and / or a coaxial to the line positionable pressure ring.

The movable elements and the or each gripper jaw are mounted on a co-rotating, preferably pot-like support structure, which has at least one in parallel to the direction of the lines extending recesses in a dimension and shape that the lines can be removed. Such a design allows a large, largely cylindrical chamber interior with relatively thin outer jacket of the twisting head in comparison with the relatively small sized receiving volume of previous gripper or twist heads.

It is particularly advantageous if a tubular sleeve is provided as a cover coaxial with the support structure, which has at least one parallel to the direction of the line extending recess for removal of the lines, and either rotates with the twisting head or locked in a rotationally fixed position. The co-rotating tube sleeve can form together with a cup-like support structure an optimal, circumferentially closed shielding of the Verdrillbereiches. When locked in a rotationally fixed position, the recesses can be overlapped by relative rotation of the support structure and tube sleeve and thus a loading and unloading opening can be released. This component can be avoided, which are spread out in the open state of the gripper to the outside very far, so that there is a risk of collision in case of accidental start The rotational movement was, especially in the homing of the system. By opening and closing the receiving chamber for the lines by means of the tubular sleeve is ensured by a compact and simple construction safe processing and easy loading and ejecting the line.

An embodiment of the twisting head is characterized in that the gripper jaws made of a metallic material, preferably hard anodized aluminum, with a corrugation or roughening of the gripper surfaces, possibly a plasma-coated surface or other surface structures, or at least partially made of an elastic material, particularly preferably of an elastomer, are formed, wherein preferably at least the coming into contact with the lines to be touched surfaces with hard particles, such as Corundum, are occupied. By gripping affected gripper jaws can be replaced easily and independently of the other elements of the twisting. Due to the hard material particles, the holding of the lines to be twisted, which is already very well fixed by the abovementioned features, is further improved.

According to an advantageous variant of this embodiment of the twisting head, an elastic support, preferably a textile, is fastened to the base body, wherein the support is preferably fastened on the elastic material and, in the case of existing hard material particles, these are located on the support. As a result, with optimum holding action and low-wear structure by the elastic support cost-saving only the top, coming into contact with the line ends layer with the adhesion-promoting particles are occupied.

The aforementioned object is also achieved by a twisting device, which is characterized in that the twisting head is designed according to at least one of the preceding paragraphs related to a twisting head, wherein the second drive is a rotary drive is that transmits the drive torque via a preferably annular drive means on a shaft of the twisting head.

It is preferably provided that the output shaft, preferably also the motor shaft, of the second drive laterally spaced and is arranged parallel to the axis of rotation of the twisting head or are.

Overall, can be achieved by the individual features a very compact design of the gripper, thus also the twisting head and the entire twisting device. The small number of parts and / or the low moving mass allows highly dynamic processes, which can be easily balanced by the largely rotationally symmetrical design of the rotating parts for the low-vibration operation. Moreover, the preferably cylindrical structure of the rotating assembly of gripper and twisting head without outwardly projecting components significantly reduces the risk of collision with adjacent components and also reduces the control effort that would otherwise be necessary to eliminate collision hazards. Also, there are no externally mounted on the rotating assembly components available that can produce a risk by throwing away at high speeds and centrifugal forces.

The very compact design with preferably tubular housing of the twisting head leaves a lot of space for the automatic insertion or ejection of the line ends or from in a substantially cylindrical twisting chamber, which has a large receiving chamber volume for the equipped with gasket and contacts line ends ,

The gripper jaws are very easy to change and on the end plate of the twisting rotor is preferably a large catch area for lines integrated. In this case, the edges of the catching area on the twisting head, in particular on the front-side end plate of the twisting head as Scraper edges act to safely strip cable ends of the gripper jaws.

Further advantages, features and details of the invention will become apparent from the following description in which embodiments of the invention are described with reference to the drawings.

The list of reference numerals is part of the disclosure. The figures are described coherently and comprehensively. The same reference symbols denote the same components, reference symbols with different indices indicate functionally identical or similar components.

A twisting device is in the illustrated embodiment of Fig. 1 to 4 from a base frame 1, to which at least one drive motor 2, which is preferably a servo drive, is mounted for the twisting head 4. By way of example, a drive belt 3, preferably a toothed belt drives the drive motor 2, the twisting head 4 with the actual, comprising several modules Gripper 11, 15, 16, 17, 19, 19 ', 20, 20', 22, 22 '(see in particular Fig. 2 ) at. In the context of the invention, other drives or other transmission elements between the drive motor 2 and 4 twisting head can be provided. Alternatively, a second twisting head can additionally be provided and preferably actuated by the same drive motor 2.

A fixed to the motor shaft (not visible) of the drive motor 2 first toothed disk 9 transmits via the drive toothed belt 3, the rotational movement via a second toothed wheel 10 on the rotatably mounted and preferably parallel to the drive motor 2 positioned twisting 4, which also includes the rotatably mounted Verdrillkopfgehäuse 8. Also in Fig. 1 visible are a gripper jaw 22 of the two existing gripper jaws 22, 22 'as well as two lines to be twisted 24,24' with different lengths of free protrusion lengths 32, 33. Alternatively, a coaxial arrangement of the drive motor 2 and 4 Verdrillkopfes possible. The Dehmomenten transmission from the drive motor 2 to the twisting 4 then takes place preferably via a rotationally stable coupling.

The second gripper jaw 22 'is in Fig. 1 not recognizable, since covered by an end-side end plate 25, is located - as in Fig. 2 can be seen - with respect to the lines 24, 24 'relative to the first gripper jaw 22. The lines 24, 24' are clamped for twisting between the gripper jaws 22 and 22 '. The stroke of the gripper jaws 22, 22 'is sufficient for clamping and secure holding of the entire line cross-sectional area for which the twisting device is designed.

The gripper jaws 22, 22 'are guided in linear guides 23, 23' in the front region of the Verdrillkopfgehäuses 8. To change the gripper jaws 22, 22 ', the end-side end plate 25 of the twisting 4 can be easily removed by loosening the screws 35. The end plate 25 also includes along at least one Part of its circumference circumferential guide grooves 36 for a tube sleeve 26 which surrounds a part of the circumference of the Verdrillkopfgehäuses 8 outside this. Shown is also a locking ring 27 of the tubular sleeve 26, at whose the base frame 1 facing side, and one of two fixedly mounted relative to the base frame 1 locking ram 28. These existing on the periphery locking ram 28 can be automatically moved, preferably pneumatically operated, and in a locking position engage in structures of the locking ring 27 and thus fix the tubular sleeve 26 in position against rotation relative to the base frame 1. In the retracted position of the locking plunger 28, the tube sleeve 26 is freely rotatable with the Verdrillkopfgehäuse 8.

FIG. 2 shows the twisting 4 in a partially cut along the coincident with a frame-fixed axis 5 axis of rotation overall view. Here it can be seen how the twisting head housing is mounted as a cup-shaped support structure 8 by means of a first rolling bearing 6 and a second rolling bearing 7 on the frame-fixed axis 5. By means of the holder 18 also fixed to the frame is preferably a pneumatic cylinder 17 as a drive for the gripper 11, 15, 16, 17, 19, 19 ', 20, 20', 22, 22 'of the twisting head 4 forming assemblies. The piston rod of this pneumatic cylinder 17 actuates via the pivot bearing 16 a fork-shaped lever 15, which is pivotally mounted on a pivot axis 14. At the fork ends of the lever 15 are respectively bolts 30 and 30 '(in Fig. 2 not shown, see Fig. 3 ) attached.

The bolts 30 and 30 'dip, as in the enlarged longitudinal section of Fig. 3 can be seen in the area between an axial roller bearing 13 and a ring 31 a. This thrust roller bearing 13 is mounted on one side on a pressure ring 11. The opposite side of the thrust roller bearing 13, on which side the bolts 30, 30 'can act, is freely rotatable. The pressure ring 11 is displaced axially displaceable by means of a sliding bearing 12 on a tubular extended region of the Verdrillkopfgehäuses 8.

The pressure ring 11 is - as again in the Fig. 2 can be seen - in engagement with two rods 19, 19 ', which are mounted axially displaceably in the Verdrillkopfgehäuse 8, extending along the length of the Verdrillkopfgehäuses 8 and on the opposite side of the thrust ring 11 of the Verdrillkopfgehäuses 8 in engagement with pins of angle levers 20th , 20 'are located. The angle levers 20, 20 'are pivotally mounted on pivot axes 21, 21' and engage at their second end turn with shaped pins in the gripper jaws 22, 22 'a.

The gripper jaws 22, 22 'are guided in their longitudinal direction in linear guides 23, 23' of the Verdrillkopfgehäuses 8. The gripper jaws 22, 22 'engage and hold the line 24, 24', when the piston rod of the pneumatic cylinder 17 is extended and via the pivot bearing 16 of the pivot axis 14 mounted on the fork-shaped lever 15 via the pins 30, 30 'attached to the fork ends the thrust roller bearing 13 and thus presses on the pressure ring 11. The pressure ring 11 exerts a compressive force on the rods 19, 19 ', which are displaceably mounted in the twist head housing 8 and which exert a corresponding force on the gripper jaws 22, 22' in the longitudinal direction thereof via the angle levers 20, 20 'pivotably mounted on the pivot axes 21, 21' ie transmitted substantially radially to the lines 24, 24 '. Thus, the lines 24, 24 'between the gripper jaws 22, 22' clamped. The gripper force over the entire gripping area of the pair of gripper jaws 22, 22 'is approximately constant, since this is determined by the pressure of the pneumatic cylinder 17. This makes setting up the twisting process relatively easy before the parameters for the twisting process are stored.

FIG. 3 shows in section the attached to the fork ends of the lever 15 bolts 30, 30 'in position between the thrust roller bearing 13 and a ring attached to the pressure ring 11 31. To close the gripper jaws 22, 22' presses the lever 15 on the bolt 30th , 30 'on the freely rotatable ring of the thrust roller bearing 13. The twisting 4 is only when closed Gripper jaws 22, 22 'set in rotation, which is ensured by a corresponding control / sensor.

To open the gripper jaws 22, 22 'push the bolts 30, 30' against the ring 31 of the displaceably mounted on Verdrillkopfgehäuse 8 pressure ring 11. This movement is effected by the pneumatic cylinder 17. Its working strokes in at least one direction can also be supported by an elastic element, for example a spring element. In this position, the gripper jaws 22, 22 'are opened and there is no Verdrillprozess instead. In addition shows FIG. 3 the spring-loaded pressure pin 29, 29 ', which secures the tubular sleeve 26 in the two rotational angular positions relative to the Verdrillkopfgehäuse 8 laterally closed or secured against rotation.

FIG. 4 shows the twisting head 4 again in a perspective overall view with a downwardly directed insertion or ejection region 34 of the end plate 25 and with lines 24, 24 '. The tube sleeve 26 closes in this position, the interior of the Verdrillkopfgehäuses 8 at its periphery. This closed position of the twisting head 4 is approached before the twisting process. Thereafter, the lock plungers 28 are retracted, and the twisting process with the twist-head housing 8 closed is performed. To eject the lines 24, 24 'after the twisting process, the twisting head 4 is stopped at an angle of 90 ° before the ejection position. Thereafter, the tube sleeve 26 is fixed on the locking ram 28 and the locking ring 27 and the twisting head 4 is then further rotated by 90 °. By this process, the tube sleeve 26 is rotated relative to the Verdrillkopfgehäuse 8 by also 90 °, so that now the side openings of the Verdrillkopfgehäuses 8 are open again. Now, for example, the pairs twisted lines 24, 24 'after opening the gripper jaws 22, 22' fall by gravity down from the Verdrillkopfgehäuse 8, for example, on a collecting surface.

Advantageously, clamping surfaces of the gripper jaws 22, 22 'can be withdrawn when opening behind the edges of the insertion 34, so that these edges act as Zwangsauswerfer the ends of the lines 24, 24'. Possibly at the gripper jaws 22, 22 'with their insulation adhesive lines 24, 24' are safely stripped for ejection and thus any disturbances in the process can be prevented. The drive mechanism of the gripper jaws 22, 22 'is designed so that they are safely withdrawn when opening behind the edges of the line-catching area, in particular the end plate 25, and thereby the lines 24, 24' for removing / ejecting safe from the gripper jaws 22, 22 'are lifted. Some cable insulation materials may experience sporadically adhere to the gripper jaws. This then leads to disruptions in the process.

Preferably interchangeable gripper jaws 22, 22 'are preferably made of an elastomer and are on the surface, or even homogeneously in the material, to increase the frictional force with hard particles (for example, corundum) occupied. The hard material particles may be applied directly to the elastomer, e.g. by melting or dissolving the elastomer; or they are glued directly on; or are on an elastic intermediate carrier (textile), which in turn is glued to the elastomer.

The invention is not limited to the illustrated embodiment. The various drives of the moving parts can be realized in a variety of ways, for example via pneumatic or hydraulic power cylinder, electric motors, magnetic drives, od. Like. Also, the power transmission can be over a variety of endless and closed power transmission means such as belts, timing belts, chains, etc. respectively. <B> LIST OF REFERENCES </ b> 1 base frame 23.23 ' linear guide 2 drive motor 24.24 ' management 3 toothed belt drive 25 Front end plate 4 twisting 26 tubular sleeve 5 Frame-fixed axle 27 Restraining 6 First rolling bearing 28.28 ' locking plunger 7 Second rolling bearing 29.29 ' Spring loaded push pins 8th Pot-like twisting head housing 30.30 ' bolt 8th' Tubular extension 31 ring 9 First toothed disc 32 cable end 10 Second toothed disc 33 cable end 11 pressure ring 34 Insertion and ejection area 12 bearings 35 screw 13 Axial roller bearing 36 guide 14 swivel axis 15 lever 16 pivot bearing 17 pneumatic cylinder 18 bracket 19.19 ' pressure bar 20.20 ' bell crank 21.21 ' Second pivot axis 22, 22 ' gripper jaws
