Description

The invention relates to a cable clamping module for clamping a cable for a cable stripping machine. The invention further relates to a separation system for a cable stripping machine for sectionally separating cable insulation from a cable and to a cable stripping machine. The invention further relates to the use of such a separation system and/or a cable clamping module for stripping a cable.

In electrical cables, insulation, which can also include cable foils for electromagnetic shielding, is used for mechanical protection as well as protection against moisture and also for electromagnetic shielding. Such cable insulation can consist of a single base material or a combination of materials.

During the production of the cable, but also during later use, it may be necessary to remove part of the cable insulation. The removal of cable insulation is also referred to as stripping. Accordingly, machines used for this are called cable stripping machines. The process of removing the insulation from the cables is complex and makes fully automated cable assembly difficult.

From the DE 10 2008 014 023 B4 Such a cable stripping machine is known. Although this enables automated stripping of cables, it has limitations with regard to the variation of the stripping length and the cable diameter. Likewise, the cable stripping machine has limitations in terms of precision in clamping and centering the cables.

Furthermore, with such cable stripping machines there is a need to reduce the complexity and in particular to reduce the manufacturing costs. In particular, the elaborately manufactured blades of the separation systems used in such cable stripping machines represent a significant cost factor.

The object of the present invention is therefore to overcome at least one of the disadvantages known from the prior art. Alternatively, at least an alternative to what is currently known should be created.

The invention solves the aforementioned problem in a first aspect by a cable clamping module according to claim 1.

In particular, the invention proposes that the cable clamping module comprises: a carrier assembly with a through opening extending along a clamping axis, a plurality of clamping jaws attached to the carrier assembly and movable between a release position and a locking position. In the release position, the clamping jaws completely release the passage opening. In the locking position, the clamping jaws block the passage opening. Preferably, at least six clamping jaws are attached to the carrier assembly. The clamping jaws each have at least one clamping surface and are designed to block the through opening at least in sections for clamping a cable, such that the clamping surfaces rest on a cable guided through the through opening.

The invention solves the problem mentioned at the beginning in relation to the cable clamping module in that the clamping surfaces are each designed to be concave and adapted so that in the locking position the passage opening can be completely closed by the clamping jaws, in particular without a gap, and in at least one clamping position which the clamping surfaces are designed to clamp a cable, to rest against the cable in such a way that the through opening is completely closed, in particular without a gap, by the clamping jaws and the received cable. This ensures that dirt does not accidentally get into the cable clamping module through the through opening. Furthermore, such a concave design of the clamping surfaces enables gap-free guidance and thus greater precision when clamping the cable. By moving the clamping jaws between the release position and the locking position in such a gap-free manner, cables with a wide variety of diameters can be clamped more precisely and the concentric alignment of the cable clamping module is improved.

A smaller number of clamping jaws, in particular fewer than six clamping jaws, causes a greater surface pressure on the contact surface of the cable per clamping jaw, which has a detrimental effect on the cable structure and puts greater strain on the cable clamping module overall.

A larger number of clamping jaws, which together form a larger contact surface with the cable, increases friction, preventing unwanted cable displacement during stripping. This is particularly advantageous for longer stripping lengths and thus increases flexibility with regard to the cables that can be stripped.

It is preferred that the clamping jaws are integrally formed. It is further preferred that the clamping jaws are manufactured by milling or eroding. Such clamping jaws preferably have a grooved clamping surface. With an integral design of the clamping jaws, their mechanical properties can be optimized and the overall manufacturing process can be simplified. For example, several layers do not have to be joined together to form the corrugated contact surface. Milling and eroding are two useful processes that allow clamping jaws with grooved clamping surfaces to be manufactured integrally.

Preferably, the carrier assembly has a number of slide bearings corresponding to the number of clamping jaws, each of the slide bearings being set up for pivotally or rotatably supporting a corresponding clamping jaw. This means that each of the clamping jaws is independently guided safely by the respective plain bearing. Rotatable storage means storage with complete mobility around the axis of rotation. With pivoting bearings, the mobility around the axis of rotation is limited.

According to a second aspect of the invention, which at the same time represents a preferred embodiment of the first aspect of the invention, the aforementioned object is achieved by a cable clamping module according to claim 4.

In particular, it is proposed that the cable clamping module has an adjusting device which is set up to arrange the cable clamping module on a corresponding assembly interface of a cable stripping machine in such a way that an axis distance and/or angle of the clamping axis is relative to a cutting axis of the cable -Wire stripping machine is adjustable. This means that a corresponding cable clamping module can be retrofitted to existing cable stripping machines. Furthermore, the precision of such machines can be increased because the cable can be precisely centered and clamped using the cable clamping module. Because the adjusting device allows an axis distance and/or angle of the clamping axis to be adjusted relative to the cutting axis of the cable stripping machine, handling is simplified and complex tools for adjusting such a cable clamping module can be dispensed with. The construction and maintenance of a cable stripping machine provided with such a cable clamping module is thus considerably simplified.

It is further preferred that the adjusting device has a mounting plate which is set up for connection to the corresponding mounting interface or can be connected to it. Furthermore, the adjusting device has an adjusting plate coupled to the mounting plate and a number of adjusting units which are set up to couple the adjusting plate to the mounting plate. The position of at least one adjusting part of the adjusting units is preferably changeable and lockable relative to the mounting plate and/or the adjusting plate in such a way that a position of the adjusting plate relative to the mounting plate can be adjusted in at least one direction orthogonal to the clamping axis. This ensures that the cable can be centered and clamped coaxially to a required axis, in this case the cutting axis of the cable stripping machine using the cable clamping module. Because the mounting plate can be connected to the mounting interface of the cable stripping machine and the adjusting plate is arranged on the cable clamping module, the position of the cable clamping module can be easily adjusted relative to the cutting axis. The adjustment plate is connected to the mounting plate and can be adjusted relative to one another. The position of the adjusting plate relative to the mounting plate can be changed in a simple manner using the adjusting parts of the adjusting unit.

The mounting plate and the adjustment plate are preferably connected to one another during adjustment by fastening means, for example screws. These screws are loosened slightly for adjustment, but still ensure cohesion.

Preferably, the adjustment units each have an adjustment means which is designed to interact with the adjustment part and to change the position of the cable clamping module by means of a rotational movement. Such adjustment means simplify the handling of the adjustment unit and thus the adjustment device. It should be understood that the actuation of such adjustment means takes place without the aid of special tools or special devices.

The carrier assembly preferably comprises a number of control rollers or control rollers corresponding to the number of clamping jaws and the clamping jaws each have a control groove, which are set up to control a movement of the clamping jaws along a control path between the release position and the locking position. Such control grooves allow the movement of the clamping jaws to be adjusted or controlled in an expedient manner. In particular, such a control can be easily automated. It is further preferred that a clamping drive is provided for driving the clamping jaws along the control track. The clamping drive preferably has at least at least a linear piston drive, in particular a flat cylinder linear piston drive, which is designed to pivot the carrier assembly about the clamping axis in order to move the clamping jaws. This means that all clamping jaws can be controlled and moved synchronously via the clamping drive and the pivoting of the carrier assembly. The control grooves thus form guide elements in the radial plane of the clamping jaws.

The use of flat piston cylinders makes the cable clamping module compact without having to accept any loss of clamping force. The flat cylinder piston has a large working surface despite the low height of the cylinder itself. The two cylinders work according to the “push-pull” principle, which increases the total torque of the carrier plate and thus the clamping force.

Preferably, the cable clamping module comprises a (first) position measuring system, which is set up to monitor the position of the clamping jaws r and to provide the monitored position to a controller. Preferably, the clamping diameter is calculated in the controller based on this monitored position. This is preferably set up to compare the clamping diameter monitored by the (first) position measuring system with a target range specified in the control and to actuate a separating device or to provide an actuation signal in the event that the monitored clamping diameter is in the target range. The cable clamping module preferably has corresponding connections for connecting the (first) position measuring system to such a controller. The control is preferably part of the cable stripping machine. The control is preferably assigned to the separation device and/or a separation system. This prevents other components, such as a separation system, from being damaged in a cable stripping machine with a corresponding cable clamping module, among other things when adjusting the cable clamping module, by a cutting process with a workpiece that is not intended for stripping.

The invention solves the aforementioned problem in a third aspect by a separation system according to claim 10.

In particular, the invention proposes that such a separation system has a separation device which comprises a knife carrier and a plurality, preferably at least six, of knives which are movably received on the knife carrier in a knife plane and are preferably fastened to the knife carrier. The knife carrier preferably has a recess for passing a cable through and the knives each have a cutting edge which is designed to separate a cable insulation from the cable passed through the recess. The task mentioned at the beginning is achieved in particular in that the cutting edges extend linearly and are arranged symmetrically about a cutting axis, with a distance between the cutting edges being changeable orthogonally to the cutting axis. Such a separating device is preferably designed according to the principle of a lens aperture. The straight cutting edges significantly reduce the manufacturing costs of the knives. In particular, the production of curved cutting edges is complex and therefore expensive.

According to a fourth aspect, which at the same time represents a preferred embodiment of the third aspect of the invention, the aforementioned object is achieved by a separation system according to claim 11.

In particular, the invention proposes a separation system with a knife drive device. The knife drive device comprises a knife drive spaced from the knife plane, in particular at a distance of 400 mm, for rotationally driving the knife drive about the cutting axis, a number of drive shafts and a corresponding number of hollow shafts, the hollow shafts for guidance and Receiving the separating device and each one of the drive shafts is set up to carry out. Because the knife drive device is arranged at a distance from the knife plane, a working area defined by the distance is created. By guiding the drive shafts through the hollow shafts, which simultaneously serve to guide and accommodate the separating device, the available working area is further increased. A high degree of flexibility can thus be created with regard to the length of the area of the cable to be stripped.

The hollow shafts preferably have a ground and hardened outer surface. This makes them particularly suitable for linear guides. The shaft cavities make it possible to position the drive shafts with drives connected to the drive shafts away from the knife plane in a machine housing, thereby increasing the power density of the separation system with comparatively small overall dimensions.

The knife drive device is particularly preferably spaced from the knife plane at a distance of 480 mm to 580 mm. In particular, there are also at least two drive shafts and accordingly two hollow shafts for guiding and receiving the separating device and for the passage of one of the two drive shafts.

The separation system preferably comprises a centering unit arranged adjacent to the knives for arranging and clamping a first section of the cable guided through the recess and a gripping device arranged at a distance from the knives, which is designed to fix a second section of the cable guided through the recess, such that the knives between the first section and the second section can be brought into contact with the cable. Because the knives can be brought into contact with the cable between the first section and the second section, their fixation is made easier and, in particular, more precise. This means that inaccuracies caused by the straight cutting edges of the knives when cutting the cable insulation can be compensated for, so that sufficient precision can be ensured as a result. The gripping device also prevents long cable lengths from sagging, thereby avoiding non-concentric cutting.

In the present case, the adjacent arrangement of the centering unit to the knives or the knife plane means that no further devices for centering are arranged between the centering unit and the knives. A touch or direct contact between the centering unit and the knives or a knife holder for fixing the knives is not necessary.

According to a preferred embodiment, the knife drive device has a toothed belt and a number of gear drives corresponding to the number of drive shafts, which comprise a gear wheel in engagement with the drive shaft and a drive part coupled to the separation system or the centering unit, the toothed belt being set up is to transmit a drive torque from the gear to the drive part for driving the knife carrier or the centering unit. A knife drive device designed in this way enables a compact structure in the area of the knife carrier and therefore does not lead to an avoidable reduction in installation space in the working area. The use of timing belts reduces transmission noise, does not require lubrication and increases resistance to contamination.

The gripping device preferably has a number of gripping elements which have a concave contact surface corresponding to a cable diameter, the gripping elements preferably being releasably mounted on a receptacle of the gripping device. Alternatively, the contact surfaces are preferably prismatic.

Further preferably, the gripping device has drive means for applying a driving force, which include a flat belt and a linear drive cooperating with the flat belt, the flat belt being set up to synchronize a movement of the number of gripping elements actuated by the driving force. The linear drive preferably comprises a first pneumatic cylinder and a second pneumatic cylinder, in particular the pneumatic cylinders are miniature pneumatic cylinders. This ensures that the cable is gripped evenly by the gripping device.

The cutting system preferably comprises a (second) position measuring system, which is set up to monitor the position of at least one knife and to interact with the knife drive device to control the distance between the cutting edges. This makes the position of the knives more precise and disadvantages due to the straight cutting edge can be compensated for. This ensures that the separation system has sufficient precision overall.

The separation system preferably also has a positioning device which has a stop rod extending in the direction of the cutting axis and a receptacle for the stop rod, the position of the stop rod being changeable relative to the knife plane and the stop rod being designed to have a distal end the recess guided cable comes into contact in order to determine a cutting length of the cable, which extends from the distal end to the knife plane.

Preferably, the stop rod is further configured to cooperate with the cable clamping module to clamp the cable with the specified cutting length and to move into the receptacle in the event that the cable clamping module clamps the cable. The stop rod comes into contact with the distal end of the cable. The positioning device preferably has a lock which is designed to close the receptacle in the event that the stop rod is completely accommodated in the receptacle. This means that the length of the part of the cable to be stripped can be flexibly adjusted. The lock also effectively prevents dirt or cable residue from penetrating into the housing in which the receptacle is formed. Thanks to the changeable position of the stop rod, the insertion depth of the cable can be adjusted very individually, with this being used in several stages to separate the cable insulation can come into contact with the blades. The cutting process is only triggered if correct positioning of the cable is detected by the second position measuring system.

It is further preferred that the separation system has a discharge device with a receptacle, which is formed below a work area. The working area is preferably defined by the positioning device and the separating device. The removal device is preferably set up to receive cable insulation that has been separated in the work area and to guide it into the receptacle, the receptacle preferably being removable from the separation system for dispensing the cable insulation or having an emptying opening. All cable residues can be effectively collected by means of a receptacle, preferably arranged below the entire working area. This is particularly necessary in order to be able to strip comparatively long cable lengths, as such remaining cable insulation could otherwise become wedged and hinder operation. A large working area, as is made possible, for example, by the spaced arrangement of the drive device in conjunction with such a receptacle for collecting the cable insulation increases operational safety and simplifies the handling of the separation system. In particular, the possibility of removing or emptying this receptacle increases comfort.

The invention solves the aforementioned problem in a fifth aspect by a cable stripping machine according to claim 18.

In particular, such a cable stripping machine includes a cable clamping module for clamping a cable and a separation system for separating cable insulation from a cable in sections. The invention solves the aforementioned problem according to the fifth aspect in that the cable clamping module and/or the separation system are set up according to one of the aspects described above. With a corresponding cable clamping module and/or a corresponding separation system, the cable stripping machine takes advantage of the advantages described above. Preferred embodiments and advantages of the preceding aspects are also advantages and preferred embodiments according to the fifth aspect of the invention and vice versa.

The invention further solves the aforementioned problem in a sixth aspect by using a separation system and/or a cable clamping module according to one of the aspects described above in a cable stripping machine or for stripping cables. By using a corresponding separation system or a cable clamping module, the invention according to the sixth aspect takes advantage of the advantages described above. Advantages and preferred embodiments of the aspects described above are therefore also advantages and preferred embodiments according to the sixth aspect of the invention.

The cable stripping machine 1 includes a cable clamping module 2 for clamping a cable 10 and a separating system 4 for separating cable insulation from the cable 10 in sections. The cable 10 has a cable diameter d _ka .

The cable stripping machine 1 further comprises a mounting interface 6 for coupling to the cable clamping module 2. The cable clamping module 2 and/or the separation system 4 are preferably connected in terms of control technology to a controller 8 of the cable stripping machine 1.

The cable clamping module 2 has a clamping axis K _A and the separating system 4 and in particular a separating device 41 of the separating system 4 has a cutting axis S _A. In 1 the course of the cutting axis S _A and the clamping axis K _A is identical, so that there is no center distance between the two axes. This condition is considered ideal.

The cable clamping module 2 includes an adjusting device 25 with a mounting plate 251, which can be connected to the mounting interface 6 of the cable stripping machine 1, and an adjusting plate 252, the position of which is adjustable relative to the mounting plate 251. The adjusting device 25 enables the identical course of the cutting axis S _A and the clamping axis K _A.

The 2a and 2 B show the cable clamping module 2 in detail. The cable clamping module 2 comprises a carrier assembly 21 with a through opening 22 extending along the clamping axis K _A. Furthermore, the cable clamping module 2 comprises a plurality of clamping jaws 23, in the present case six clamping jaws 23, which are attached to the carrier assembly 21. The clamping jaws 23 each have a clamping surface 23a, which is designed to be connected to the cable 10 (cf. 1 ) to come into contact. The clamping surfaces 23a have a corrugated structure with elevations and depressions, so that the cable 10 is prevented from slipping through the cable clamping module 2.

Like in particular 2 B shows, the adjusting device 25 has a number of adjusting units 253, each of which has a number of adjusting parts 254. The adjusting parts 254 are designed to couple the adjusting plate 252 to the mounting plate 251. The position of at least one of the adjusting parts 254, preferably all of the adjusting parts, is relative to the mounting plate 251 (cf. 1 ) and/or the adjusting plate 252 can be changed and locked, so that the position of the adjusting plate 252 relative to the mounting plate 251 can be adjusted in at least one direction orthogonal to the clamping axis K _A. The adjustment units 253 preferably further comprise adjustment means (not shown), which are designed to interact with the respective adjustment part 254 and to change the position of the cable clamping module 2 and in particular of the adjustment plate 252 relative to the mounting plate 251 by means of a rotational movement. The adjustment means are preferably coupled to the mounting plate 251. More preferably, the adjusting parts 254 are accommodated and guided at least in sections in the mounting plate 251, the adjusting means being set up to change the position of the adjusting parts 254 within guides (not shown) in the mounting plate 251.

How further? 2 B As can be seen, the carrier assembly 21 is coupled to the clamping drive 26 via two articulated connections 211. In detail, the carrier assembly 21 is coupled via the joint connection 211 to a piston 263, which is guided at least in sections in a flat cylinder 262 of the flat cylinder linear piston drive 261.

A position measuring system 27, which in the present case is a first position measuring system, is also provided, which is set up to monitor a clamping diameter d _k defined by the position of the clamping jaws 23 and preferably to the controller 8 (cf. 1 ) to provide. The controller 8 is also preferably set up to compare the monitored clamping diameter d _k with a target range specified in the controller 8 and to actuate the separating device 41 of the separating system 4 only in the event that the monitored clamping diameter d _k is in the target range.

The 3a and 3b show a section of the cable clamping module 2 and in particular the movement of the clamping jaws 23 in detail. In 3a the clamping jaws 23 are shown in a release position F and in 3b the clamping jaws 23 are shown in a locking position S.

In the release position F according to 3a the clamping jaws 23 completely expose the through opening 22, so that the clamping diameter d _k corresponds to the diameter of the through opening 22. The clamping jaws 23 are fastened in the carrier assembly 21 and are guided in their movement. In detail, the cable clamping module 2 has a number of plain bearings 24 corresponding to the number of clamping jaws 23, by means of which the clamping jaws are mounted in an articulated manner on the carrier assembly 21. If the carrier assembly 21 is actuated and thus pivoted by means of the clamping drive 26 by a movement of the pistons 263, this leads to a rotation of the clamping jaws 23 around the plain bearings 24.

To control the movement of the clamping jaws 23, the clamping jaws 23 also have control grooves 231 and the carrier assembly 21 has corresponding control rollers 212, which are movably guided within the control grooves 231. Through the interaction of the control grooves 231 and the control rollers 212, the movement of the clamping jaws 23 between the release position F and the locking position S is fixed and limited. Pivoting the carrier assembly 21 thus requires a simultaneous movement of all clamping jaws 23 for uniformly releasing or blocking the through opening 22.

The clamping jaws 23 preferably have concavely curved clamping surfaces 23a, which are in the locking position S according to 3b a gap-free closing of the through opening 22. The precision of the cable clamping module 2 is thus increased even with small cables and the ingress of dirt and the like via the cable clamping module 2 is avoided.

4 shows the separation system 4 with a separation device 41, a knife drive device 42, a centering unit 43 and a gripping device 44 which interacts with the centering unit 43. Furthermore, the separation system 4 comprises a second position measuring system 45 and a positioning device 46 for positioning or arranging the cable 10 in the cable stripping machine 1 (cf. 1 ) and in particular the separation system 4.

The knife drive device 42 includes a knife drive 221, to which drive shafts 422 are operatively connected. The drive shafts 422 are guided within hollow shafts 423. The hollow shafts 423 simultaneously serve for the guided positioning of the separating device 41 and the centering unit 43. The freeing device 44 is driven via a parallel drive, which includes the linear drive comprising two pneumatic cylinders and the toothed belt.

As shown in particular in the detailed view 1a As can be seen, the drive shafts 422 are driven by gear drives 424, which have at least one gear 424a coupled to the drive shafts 422, as well as drive parts 424b for driving the gears 424a. A toothed belt 425 is provided for transmitting the driving force to the gears 424a. The knife drive device 42 is arranged at a distance A3 from the separating device 41 and in particular the knife plane E _M in which the knives 412 (cf. 5a and 5b) the separating device 41 move.

Furthermore, a working area 48 defined by the distance A4 is provided, the distance A4 being defined by the distance between the knife plane E _M and a corresponding anchor plate 49. A receptacle 462 for receiving a stop rod 461 of the positioning device 46 is formed in the anchor plate 49. The receptacle 262 in the anchor plate 49 can be completely closed by a lock 463 in the event that the stop rod 461 is completely received. The stop rod 461 can be moved in the direction of the separating device 41 or away from it in order to position the cable 10 (cf. 1 ) to allow.

The 5a and 5b show the separating device 41 in detail. The separating device 41 comprises a number of knives 412, which are attached to a knife carrier 411 and are movably mounted. The knives 412 are designed to insulate the cable passed through the recess 413 from the remaining cable 10 (cf. 1 ) to separate.

The knives 412 are rotatably mounted about bearing points 414 on the knife carrier 411.

The knives 412 each have a straight cutting edge 412a, such that the knives 412 cannot be guided along one another without a gap. In 5b the separating device 41 is shown in a zero position and the knives 412 completely close the recess 413.

To guide the movement of the knives 412, these have guide grooves 412b, in which guide pins 411a of the knife carrier 411 are guided. The movement of the knives 412 is therefore also controlled and limited.

6 shows the gripping device 44 in detail. In the present case, the gripping device 44 comprises two gripping elements 441, which are designed to correspond to one another but are mirror-inverted. The gripping elements 441 are coupled to one another via a flat belt 442 and are driven via a linear drive 443. The gripping elements 441 are transverse to the direction of the cutting axis S _A (cf. 1 ) guided.

The gripping elements 441 form a cylindrical receptacle for the cable 10 (cf. 1 ), which consists of two half-shells with concave contact surfaces 441a. By moving the gripping elements 441 towards each other in a direction transverse to the cutting axis S _A , the half-shell-shaped gripping elements 441 come into contact with the corresponding cable 10 and thus grip or fix it.

By using the flat belt 442, it is possible for the movement of the two gripping elements 441 to be synchronized, thus ensuring a uniform movement of the two gripping elements 441. Consequently, the gripping elements 441 come into contact evenly with the cable 10 to be fixed in this way. The cable 10 is thus fixed or at least guided on the one hand by the centering unit 43 and on the other hand by the gripping device 44, whereby the cable insulation can be separated from the cable 10 by means of the separating device 41 in the knife plane E _M using the knives 412. The gripping device 44 prevents the cable from sagging. Through the centering unit 43 and the gripping device 44 the Positioning of the cable 10 more precisely and avoiding sagging and other disadvantageous paths of the cable. This enables greater precision when setting the cross section to be stripped and enables sufficient precision of the cutting system 4 even with straight cutting edges 412a.
