Definitions

  • the invention relates to an apparatus for connecting two mutually crossing cable portions at respective cable intersections of a netting formed from one or more cables, with two wires which are to be wound around the cable portions at the intersections.
  • the problem of the present invention is to provide an apparatus of the kind set forth above, in which a common drive is provided for the two winding elements in a simple manner.
  • the two hollow wheels guarantee a support for winding elements which are for example of a cylindrical configuration and which contain the wire receiving means which in known manner can be in the form of bores extending in the winding elements parallel to the common axis of rotation.
  • the support can be provided on a common frame which has two mounting plates, the hollow wheels being mounted rotatably on the two mounting plates.
  • the drive for the hollow wheels and thus the wire receiving means carried by the hollow wheels, about the common axis of rotation can be in the form of a manual drive, for example a hand crank. It is also possible however to use a motor for the common drive, for example a pneumatic motor, or a hydraulic motor, or an electric motor. Possibly the hand crank or the motor drive can be optionally flange-mounted to a common drive shaft by way of which the drive moment is transmitted to the hollow wheels.
  • the apparatus may have two transmission assemblies using pulling means, or transmission assemblies using gears, or transmission assemblies with a similar action which drive the hollow wheels in opposite directions of rotation.
  • a transmission assembly using pulling means is used for each of the hollow wheels.
  • cylindrical winding elements 18 and 19 which are of a configuration as is known from EP 0 428 848 A1 are disposed in hollow wheels 4 and 5.
  • the arrangement is such that the two winding elements 18 and 19 and the two hollow wheels 4 and 5 are rotatable about a common axis of rotation as indicated at DA.
  • the hollow wheels 4 and 5 are rotatably mounted on mounting frame plates 6 and 7.
  • hollow-cylindrical mounting assemblies 35 and 36 are provided on the mounting frame plates 6 and 7.
  • the hollow-cylindrical mounting assemblies 35 and 36 each include respective hub portions 37 and 38 for rotatably supporting the hollow wheels 4 and 5.
  • the hollow wheels 4 and 5 also each have a respective ring gear 39 and 40 engaged by drive chains 15 and 16 for driving the winding elements 18 and 19 in opposite relationship, as will be described in greater detail hereinafter.
  • the winding elements 18 and 19 are mounted non-rotatably in the hollow wheels 4 and 5, for example by means of splines 25 and 26. The rotary movement of the hollow wheels 4 and 5 is therefore transmitted to the winding elements 18 and 19.
  • the winding elements 18 and 19 are mounted displaceably in the axial direction in the respective hollow wheels 4 and 5. In that way it is possible for the two winding elements 18 and 19 to be displaced axially in mutually opposite directions during the operation of winding a wire around first and second cable portions as indicated at 2 and 3 in Figures 4 and 5, which are adjacent to a cable intersection as indicated at 17 in Figure 4.
  • the winding operation will be described in greater detail hereinafter with reference to Figures 4 and 5.
  • openings 22 and 23 are provided in the winding elements 18 and 19 and in the two hollow wheels 4 and 5 which can be aligned with each other in such a way that the two cable portions 2 and 3 which are to be joined together at a respective intersection 17 can be laid around the common axis of rotation DA, as shown in Figures 4 and 5.
  • the winding elements 18 and 19 also have wire receiving means 20 and 21 respectively in the form of through bores which extend parallel to the common axis of rotation DA. As can be seen from Figure 4, the two bores forming the wire receiving means 20 and 21 are aligned with each other for a respective wire 12 or 13 to be pushed therethrough.
  • the apparatus has an actuating arrangement illustrated in the form of a piston-cylinder arrangement 11 shown in Figure 2, which produces the drive for the axial movements of the winding elements 18 and 19.
  • the drive force can be transmitted by way of forks 29 and 30 which are supported on the mounting plates 6 and 7 at fork support brackets 27 and 28 respectively.
  • Axial displacement of the winding elements 18 and 19 in the hollow wheels 4 and 5 can also be effected automatically by virtue of the turns of wire on the cable portions 2 and 3 becoming extended in the axial direction.
  • the winding elements 18 and 19 can be moved back into their starting position for a fresh winding operation.
  • a common drive is provided for the illustrated embodiment.
  • the torque produced by the common drive is transmitted by way of a common drive shaft 10.
  • Non-rotatably carried on the common drive shaft 10 are drive wheels 8 and 9 which can be in the form of chain wheels or chain gears.
  • the drive wheels 8 and 9, in the form of chain wheels, engage with the drive chains 15 and 16 which in turn are engaged with the ring gears 39 and 40 on the hollow wheels 4 and 5.
  • the drive chains 15 and 16 engage the portion of the periphery of each of the ring gears 39 and 40, which is disposed at the bottom thereof when viewing Figure 1. Those regions of the ring gears 39 and 40 on the hollow wheels 4 and 5 are most closely adjacent to the common drive shaft 10.
  • one drive chain 15 is in engagement with the bottom part of the tooth configuration of one of the two drive gears 8 and 9, for example the bottom part of the periphery of the tooth configuration of the drive gear 8. That part of the tooth configuration of the drive gear 8 is at the side of the drive gear 8 which, relative to the drive shaft 10, is remote from the respectively associated hollow wheel to be driven, for example the wheel 4.
  • the other drive chain 16 engages with the other drive wheel, for example the drive wheel 9, at the portion of the tooth configuration thereof which, with respect to the drive shaft 10, is in opposite relationship to the engagement between the chain 15 and its drive gear 8.
  • the part of the drive gear 9 which is engaged by the drive chain 16 is towards the associated hollow wheel 5 which is to be driven thereby.
  • the drive wheels 8 and 9 which are both carried on the drive shaft 10 are driven in the same direction.
  • the drive chains 15 and 16 engage the drive wheels 8 and 9 at opposite sides thereof, as can be clearly seen from Figure 1
  • the drive chains 15 and 16 are driven in mutually opposite directions, and those mutually opposite directions are accordingly transmitted to the respective ones of the hollow wheels 4 and 5. Therefore the two hollow wheels 4 and 5 are driven in opposite directions of rotation about the common axis DA.
  • the common drive as indicated at 14 in Figure 2 may be a manual drive or a motorised drive.
  • the manual drive may be a crank which is fitted on to the common drive shaft 10.
  • a suitable motorised drive is by means of a hydraulic motor or a pneumatically operated motor or an electric motor.
  • direction-changing shafts 31 to 34 are provided for guiding the drive chains 15 and 16 in the required configuration, being mounted on the two mounting plates 6 and 7. There are four such direction-direction shafts 31 to 34, for each of the two chains 15 and 16.
  • the two mounting plates 6 and 7 are feed to a main body 1.
  • the main body 1 is in turn fixed in a holder 41 which can be in the form of a cylindrical member, as shown in the illustrated embodiment.
  • the holder 41 can serve as a handle, in particular for mechanical actuation of the winding assembly shown in the drawings.
  • the holder 41 can be used to move the winding assembly manually from the position shown in Figure 4 into the position shown in Figure 5.
  • the winding assembly can be turned by hand about a vertical axis SA (see Figure 2) which extends perpendicularly to the common axis of rotation DA.
  • that turning movement can also be produced mechanically, by means of a crank device.
  • the holder 41 is mounted rotatably in a frame generally indicated at 42. That frame can be a component of the carriage which in EP 0 428 848 A1 is guided in the XY-co-ordinate guide means. In that arrangement, the holder 41 can be interchangeably fitted in the crank device which is shown in Figures 1 and 3 and which will be described in greater detail hereinafter.
  • a cylindrical guide 43 for the holder 41 is provided on the frame 42 .
  • the guide 43 is in turn mounted rotatably in a mounting arrangement 44 on the machine frame as indicated at 43.
  • the holder 41 is non-rotatably connected to the guide 43 so that it can be rotated together with the guide 43.
  • the non-rotatable connection between the guide 43 and the holder 41 can be formed by splines as indicated at 45.
  • a crank 46 is provided for rotary drive for the guide 43 in the mounting arrangement fixed to the frame 42.
  • the crank 46 is engaged by a piston-cylinder arrangement at 47 in Figure 3, by means of which the crank 46 and therewith the holder 41 can be pivoted through 90°. That pivotal movement through 90° is about the vertical axis SA when the arrangement of the winding elements 18 and 19 is moved into the respective positions shown in Figures 4 and 5.
  • the holder 41 is in the form of a handle.
  • the holder 41 can be displaced axially in the guide 43 to permit axial sliding movement of the holder 41 and therewith the winding arrangement secured thereto.
  • That axial displacement can be effected by a drive device, for example in the form of a further piston-cylinder arrangement 48.
  • That axial displacement serves to provide corresponding relative displacement of the winding elements 18 and 19, together with the associated hollow wheels 4 and 5, with respect to the cable portions 2 and 3 which are to be joined together at the intersections 17. In that way the winding elements 18 and 19 and the associated hollow wheels 4 and 5 can be moved into such a position that their common axis of rotation DA can be moved into alignment with the respective cable portions 2 and 3 to be wound around (see Figures 4 and 5) and removed again from that position.
  • the winding operation is effected in the same manner as described in EP 0 428 848 A1 and results in the cable connections known therein at the cable intersections.
