Definitions

  • the invention relates to a cable guide for cable stripping machines.
  • Cable stripping machines are often designed as continuously operating, endless cable processing machines and provide - before, after and between drive devices and cable processing devices - guides for the cable to be processed. These guides are mostly formed by pipes, some of which have funnel-shaped inlet areas.
  • these tubes can be swiveled (longer guide tube for PS 9500 Powerstrip) or slidable (shorter guide tubes for PS 9500 Powerstrip) or permanently mounted, so that cable pieces can either be fed to a processing device or in a direction pointing away from the processing device, or that the Guides can be removed from their functional position, or that guides are always arranged in the same place.
  • the indicated obvious and already published solution has the following disadvantage compared to the original solution with exchangeable guide tubes: Since the axis of rotation of the turret must lie outside the center of the cable, the lateral size increases. The cable must be removed from the guide during the rotating process of the turret and at the same time no cable feed can take place. If guide tubes are selected incorrectly, the original as well as the turret solution is cumbersome in that the cable has to be completely unthreaded before the guide can be changed. This is disadvantageous and time-consuming for the user.
  • the known solutions can only be used within the framework of existing, graduated guide tube diameters, so that cable diameters lying between the stages of the individual guide tubes can only be routed more poorly than cable diameters that exactly match the stage in question.
  • US-A-4489490 describes a hand-held device for cable slitting and stripping, in which a prismatic support is provided which centers the cable.
  • the prismatic support is juxtaposed with a height-adjustable counter-holder that presses the cable against the prismatic support and thus centers it laterally in one direction. With this setup, there is a centric one Guiding is not possible because the cable is more or less deep in the prismatic support depending on the cable diameter.
  • the US-A-4181047 describes a cable stripping device with a total of four, in pairs one behind the other arranged guide rollers, which seen in cross section form a rectangular guide channel (see Fig.3), which is however open on two sides and thus no complete and all-round guidance and can support the cable.
  • US-A-5979286 specifies a two-sided guide in which two elongated guide strips can be displaced relative to one another by means of threaded spindles. This structure thus also does not allow all-round guidance and does not result in continuous centering of the cable, since the center of the cable moves up or down depending on the cable diameter.
  • US-A-5820008 shows a guide in FIGS. 7 and 8 which, controlled by a cone, permits the displacement of two jaws with guide surfaces (228 and 248). This allows the jaws to be closed to a small cable diameter; however, the center of the cable also shifts depending on the cable diameter.
  • This structure like the one immediately above, also lacks a real concentric guide, since there are no symmetrical contact surfaces for a cable.
  • the invention therefore sets itself the task of facilitating the manipulation with guides in connection with a change in the cable diameter.
  • it sets itself the goal of enabling continuous adjustment to different cable diameters.
  • the solution of the two tasks consists in at least one tube, the inside diameter of which can be changed at least approximately symmetrically to the longitudinal axis of the tube by changing the tube geometry.
  • Such a change in geometry can be brought about, for example, by means of a segment-like structure, the segments of which can be adjusted relative to one another in such a way that the inner tube diameter changes continuously. It can also be achieved in that the tube wall is flexible and can be stretched or compressed.
  • the tube can be constructed as a spring which is spiral in cross-section and which can be adjusted in its inner diameter by external forces.
  • a specific embodiment of the invention provides that the segments are formed from elongated, rigid plates which are relative to one another, comparable to an iris diaphragm in a camera or comparable to the centering jaws in the rotary box of the PS 9500 Powerstrip, in a model MP 8015 or JS 8300 Applicant.
  • the centering jaws of the rotary box and those of the JS 8300 are stationary, while the centering jaws of the MP 8015 model rotate with the knives.
  • the elongated plates are several times longer than the maximum adjustable diameter of the guide tube.
  • Another specific embodiment uses an elongated coil spring or a coil spring body made up of coil spring segments, which can be operated with a variation in diameter such that the or the inner end (s) of the coil spring or the coil spring segments on the inner wall of the coil spring or lie against the inner wall of an adjacent spiral spring segment, or along the slide.
  • Conventional spring metals for example spring steels or also plastics, in particular fiber-reinforced plastics, are suitable as materials for the spiral spring (segments).
  • Both of the specified design variants can also be combined with one another by connecting spiral spring segments to the rigid segment plates and thus sealing the segment plates against one another.
  • segment plate solution lies in a robust, rigid construction, while the advantage of the coil spring or coil spring segment construction means less mechanical effort.
  • a seal between tube segments sliding against one another can be advantageous for certain types of cable (in particular for fine strands) in order to prevent such strands from jamming.
  • a further development of the invention provides that the adjustment takes place by means of a motor, in particular electronically, so that an operator or a sensor-controlled controller sets the required inner pipe diameter.
  • Versions are particularly advantageous in which the cable information - be it detected by sensors or entered by programming - is automatically set to the correct diameter via the machine control.
  • Fig. 1 shows an exploded view of the structure of a universal guide, starting from a cover 3, a multi-part guide segment body 4, which is held by a guide holder 1, is shown.
  • the guide segments 17 are opened or closed by means of elongated guide holes 18 in the cover 3 via the cylindrical pins 12 and 13.
  • the guide segments 17 are connected to the respectively assigned parts of the guide segment body 4, if appropriate formed in one piece with them.
  • Per part guide segment body 4 cylinder pins 12, 13 are also firmly connected to it.
  • the parts of the guide segment body 4 support one another or slide against one another during adjustment.
  • Cylinder head screws 11 clamp the cover 3 with the guide holder 1 and a scale cover 5, which is connected to a tubular casing 19.
  • the casing tube 19 and / or the cover 3 or the guide segments 17 can be provided at its end with, for example, a funnel-shaped conical inlet area.
  • a cam plate 2 On a guide holder 1 sits on a slide bearing 6, a cam plate 2, on which the scale cover 5 by means of a nut, e.g. a knurled nut 7 is held axially adjustable.
  • the scale cover 5 has the task of making a selected pipe diameter setting adjustable for a user.
  • FIG. 1a shows the universal guide according to the invention according to FIG. 1 in the assembled state.
  • FIG. 2 shows an embodiment of a universal guide, which is characterized by particularly short guide segments 17a. Depending on requirements, it is fixed in position, or analogous to the known vertically displaceable guides before and after the cutter head (with PS 9500 Powerstrip), vertically displaceable, as not shown. However, it has no casing tube 19, as shown in Fig.1.
  • Fig.2a shows the embodiment of Fig.2 in the assembled state.
  • FIG. 3 shows a variant of FIG. 1, in which the guide segments 17b are particularly long and in which the entire guide head is pivotably held via a deflection 16, which acts as a carrier.
  • the deflection 16 is, as is known per se (so-called whistle with PS Powerstrip 9500), controlled by suitable mechanics or by a motorized, pneumatic or electromagnetic drive, for example, and driven so that the longitudinal axis of the universal guide is once in the cable axis lies and runs obliquely to it when swung out.
  • the deflection is connected via holding plates 20 and cylinder head screws 15 to an extended holding part 21 of the scale cover 5.
  • 3a shows the structure according to Fig.3 in the assembled state.
  • the control of the guide segments 17, 17a and 17b is similar to that of the clamping or centering jaws of the machines of the applicant specified in the introduction to the description and can be found, for example, in the applicant's US-A-5010797. Details of the control, such as the drives, spring resets, etc., as well as variants thereof, can easily be derived or adopted by the person skilled in the art from this prior art. The content of the aforementioned US-A is therefore also considered to be incorporated by reference in this application text.
  • the pins 12, 13 shown in the figures can thus also be replaced, for example, by lever arms (31 and 32) from FIG. 13 of the US-A.
  • FIG. 6 A variant of the invention based on another principle is shown in FIG. 6, in which resilient segments 22 engage in one another in such a way that they enclose a variable tube space and can be caused to reduce the diameter by pressure from the outside (arrow A), with reduction of pressure, however, the segments 22 expand again to a larger diameter.
  • the pressure can be applied by rods, spindles or eccentric control cams known per se, which are not shown in detail here.
  • Figure 7 Another somewhat different principle can be seen from Figure 7, in which a single elongated coil spring 23 is used as a guide tube. This spring 23 is constructed in such a way that it tends to open to the largest inside diameter. If there is pressure from outside (arrow B), the inside diameter is reduced by the inside end of the spiral spring 23 moving along the spring wall in the closing direction (or rolling in).
  • FIG. 8 Another variant is shown symbolically in FIG. 8, in which a wide spring 24 serves as a guide tube according to the principle of a wrap. One end of the spring 25 intermeshes through the slot through the other end 26, the two ends being comb-shaped. As a result, the diameter of the guide can be adjusted over a wide range by a tensile force (arrow C) at the two spring ends 25, 26. If the center of the guide should always remain in the same place, the tensile force at both spring ends 25 and 26 must be symmetrical and a reduction in diameter additionally compensated for by a lateral shift of the entire structure (cross arrow D).
  • Fig. 9 shows a further embodiment of a radially adjustable cable guide.
  • This has three guide rollers 28, which are radially adjustable in the direction of the arrows “E”, and associated guide plates 29.
  • the guide plates 29 are preferably made of elastic spring steel and are connected to the guide rollers, for example, by welding or riveting.
  • the radius of curvature R corresponds to the guide plates 29 about half the diameter d of the smallest cable 27 to be accommodated. With larger cable diameters, the guide plates 29 can thus adapt to the outer diameter of the cable in the radius R.
  • the free ends of the guide plates 29 are rolled up or bent over in order to prevent damage to the surface of the cable by sharp Avoid edges.
  • 11 r shown as an exploded drawing, show a further possibility of an adjustable cable guide.
  • guide segments 34 are supported at both ends by means of pins 35.
  • a toothed segment 33 with teeth is attached to each of these guide segments.
  • the teeth of the toothed segment 33 engage from the inside in a toothed ring 31 which is rotatably mounted in a housing 30.
  • a pin 38 is radially fixed on the outside, which is movable in a recess 36 in the housing 30.
  • Two coaxial adjustment screws 39 are arranged so that they penetrate the housing 30, the free ends of which come loose on one side of the pin 38 each.
  • the toothed ring 31 is rotated via the pin 38 in FIG. This in turn drives the movably mounted guide segments 34 via the tooth segments 33.
  • the size of the recess 36 in the housing 30 determines the maximum angle of rotation and thus the smallest and largest possible diameter of the cable guide.
  • Locking screws 40 serve to fix the adjusting screws 39.
  • the entire guide segments 34 are arranged in a tubular casing 37.
  • a cover 32 that closes the housing 30 is fastened by means of hexagon socket screws 41.
