Definitions

  • the invention relates to a device for applying soft-elastic sealing grommets to electrical cable ends, in particular for moisture-protected plug elements or the like.
  • a device according to the features of the preamble of claim 1 has become known from EP-A-0 159 006.
  • an oscillating conveyor designed as a sorting conveyor conveys sealing spouts upward in a helical shape.
  • the longitudinal center axes (axes of rotation) of the spouts have an approximately vertical position.
  • the grommets When the grommets have reached their uppermost conveying position, they are moved in the vertical position of their longitudinal central axes via a horizontal rigid conveying trough to a point at which they are passed on to a baking tool by a quite complex conveying device and finally pushed onto the cable ends.
  • the conveyor device forms a relatively complicated mandrel device at the aforementioned location, which picks up each spout and then, after a rotation of approximately 90 °, transfers it to a horizontal position.
  • the spout is taken over by another component of the conveying device, namely by a swivel device with a receiving pin, which can be moved together with the spout into the movement path of an axially reciprocating turnstile-like device.
  • the turnstile arms are at the free ends provided with baking tools, the top one of which can be pushed over the grommet held by the swiveling mounting pin.
  • the grommet held by the baking tool After the turnstile is initially moved back axially, the grommet held by the baking tool finally reaches the horizontal mounting position of its longitudinal central axis after a cyclical rotation through a total of 180 °, in which it is aligned with the cable end coaxially.
  • EP-A-0 159 006 The device known from EP-A-0 159 006 is perceived to be in need of improvement because of its complicated, complex and more prone to malfunctioning construction.
  • the object on which the invention is based is to develop a device which, with a simpler design, allows both adequate reliability and rapid operation.
  • this object is achieved in that the sleeve tool and / or the centering mandrel also form the means of the conveying device, which move the respective grommet into the horizontal mounting position of its longitudinal central axis, in which the grommet of a coaxial, the temporary centering receptacle of the line end serving sleeve tool and / or is received by a centering mandrel, and wherein the sleeve tool and / or the centering mandrel simultaneously form the means of the conveying device, which transfer the spout to the baking tool.
  • either the sleeve tool and / or the centering mandrel not only serve to convert the spout, which is initially in its vertical position of its longitudinal axis, into a horizontal position. Rather, according to the invention, the sleeve tool and / or the centering mandrel also serve to form a total of a conveying device which puts each spout in the horizontal mounting position of its longitudinal central axis and transfers it to the jaw tool while avoiding additional conveying means.
  • the invention provides that the sleeve tool and / or the centering mandrel as an intermediate conveying means, such as a vibrating trough or driver conveyor, which conveys the respective spout in the vertical position of its longitudinal axis in the horizontal conveying direction.
  • an intermediate conveying means such as a vibrating trough or driver conveyor
  • the invention furthermore alternatively deals with two devices, of which the first device is more suitable for fitting nozzles on wire ends that have already been stripped.
  • the alternative second device is particularly predestined for fitting cable ends with an insulation jacket with grommets.
  • the invention provides that the respective grommet rests on the die, which is coaxial with it and can be moved vertically up and down, following the intermediate conveying means.
  • the sleeve tool is at a distance exceeding the axial length of a spout, ie with a free space, above the die coaxially with it and also coaxially with one above the Sleeve tool arranged, vertically up and down centering mandrel can be aligned.
  • the sleeve is pushed onto the sleeve tool in the following peculiar way:
  • the centering mandrel is pushed axially through the sleeve tool and passes through the sleeve to the die.
  • the centering mandrel therefore bridges the free distance between the sleeve tool and the spout or between the sleeve tool and the die (including the spout).
  • the centering mandrel serves as a guide when pushing the grommet onto the sleeve tool.
  • the insertion of the sleeve tool is conical, the subsequent sleeve casing is circular cylindrical with a diameter that is significantly larger than that of the free end of the cone.
  • a radial expansion of the spout is accordingly associated with the pushing-on process, without an expandable expansion sleeve being absolutely necessary for this.
  • this is done in that the sleeve tool is held by a rotating device which can be pivoted with a circumferential angle of 180 °, the axis of rotation of which is arranged in a plane with the common longitudinal axis of the centering mandrel and die and is inclined by 45 ° with respect to that common longitudinal axis .
  • the rotating device is designed in the manner of a revolver and carries two identical sleeve tools spaced apart from one another at a circumferential angle of 180 °.
  • Revolver-like structures for receiving sealing sleeves are known per se from DE 37 15 708 A1 (see FIG. 2 there; column 5 lines 18-47).
  • the known turret arrangement is, however, not comparable to the one according to the invention because, in the known, the sealing sleeves are fed pneumatically in their vertical position (see DE 37 15 708 A 1, Fig. 2, column 5, lines 44-47).
  • the known turret arrangement also carries neither an expansion sleeve nor a centering mandrel.
  • the known turret arrangement is provided with a plurality of circumferentially distributed chambers for receiving spouts; in contrast to the invention, it is therefore advanced - only progressing with comparatively small circumferential angle steps.
  • the sleeve tool which is pivoted into the horizontal position of its longitudinal axis, is preceded by the jaw tool arranged between the sleeve tool and the insertion device for the line end.
  • This jaw tool is able to grip around the grommet located on the sleeve tool while the insertion device is the line or. Push the cable end into the sleeve tool.
  • the sleeve tool which can be moved back and forth in the horizontal direction, expediently together with the rotating device, is now pulled out of the central opening of the spout, while the baking tool strips the spout onto the line end.
  • the second variant of the aforementioned alternative is essentially characterized in that the centering mandrel forming the conveying device engages from below in the respective spout, which is fed in by means of a forced conveying means in the vertical position of its longitudinal axis and is in a ready position, for example at a stop horizontal position of its longitudinal axis pivoted and passed there to the baking tool.
  • the driver designed as a slide 15 is driven to reciprocate in the horizontal direction by means of the piston rod 16 of a pneumatic piston-cylinder unit 17.
  • the slide 15 conveys in each case a spout 13 which has entered the conveying trough 18 of the driving conveyor 14 from the sorting conveyor 11, while the spout 13 remains unchanged with its longitudinal central axis x in a vertical position, according to FIG. 1 to the right.
  • the spout 13 reaches the end face of one with its central longitudinal axis - with u - vertical die 19.
  • the area 22 in order to stabilize the sleeve tool 20, it is also possible to design the area 22 as a cone that widens only slightly from the area 21.
  • a centering mandrel 23 which can be moved up and down in accordance with the double arrow y, moves through the sleeve-like tool 20 and through the central opening the spout 13 into the area of the die 19. In this way, the spout 13 is centered with respect to the sleeve tool 20 by means of the centering mandrel 23.
  • the die 19 which can be moved up and down along guide y and guide bushings 26, via a bracket 27 and via a translatory drive 28 along y, can completely push the spout 13 onto the sleeve tool 20 via the conical end section 21, the spout 13 being widened.
  • the sleeve tool 20 is arranged on a rotating device 29, which can be moved back and forth in the horizontal direction on a support 30 along the double arrow a.
  • the pivot axis of the rotating device 29 is denoted by z.
  • the pivot axis z is in a plane with a central axis through the centering mandrel 23, the sleeve tool 20 and through the die 19 and u.
  • the axis of rotation z and the axis u are in one plane and form an angle ⁇ of 45 ° with one another.
  • a further sleeve tool 20 is arranged, which is only shown in broken lines in FIG. 1. Since the rotating device 29 can carry out an uninterrupted swiveling movement of 180 °, after such a 180 ° swiveling, one sleeve tool 20 alternatively reaches the previous position of the other sleeve tool 20.
  • the grommet 13 is pivoted in alignment behind the jaw tool, which is denoted overall by 31 and which is in alignment with the insertion direction E of a line end K (not shown in FIG. 1) (see FIG. 5) of a cable processing machine (also not shown) located.
  • the insertion direction E runs coaxially and horizontally together with the longitudinal center axis x of the spout 13 shown in FIG. 5.
  • the pivoting movement of the rotating device 29 can be carried out continuously or reversely because of the 180 ° pivoting angle.
  • the construction of the jaw tool 31 can be seen in more detail from FIGS. 2 to 5, which has two gripping jaws 32, each of which receives an insert jaw 33.
  • the insert jaws 33 each form a stepped recess at 34, which roughly follows the outer contour of the spout 13. In this way, the recess 34 at 35 and 35a is approximately circular Stop surfaces represent, which can bear against a collar 36 and against an end face 36a of the spout 13.
  • Each insert jaw 33 is pivotable at 37 and is resiliently resiliently mounted against the restoring force of a helical compression spring 38.
  • the pivoting movement of the insert jaws 33 in the direction of the spout 13 can be adjusted in each case by means of a set screw 39.
  • both gripping jaws 32 are provided with their outer regions facing the insertion device (at E) for the line end K between their jaw surfaces with two mutually opposite recesses 53. The latter complement each other to form an approximately frusto-conical funnel T which widens towards the line end K.
  • the embodiment according to FIG. 1 allows a high working frequency, because while in the upper position of the one sleeve tool 20 the stripping of a spout 13 takes place on a line end K, while at the same time a spout 13 on the lower part above the die 19 other sleeve tool 20 can be pushed.
  • the intermediate conveyor 14 following the sorting conveyor 11 with its container 12 in the conveying direction F (see also FIG. 1), which also forms a conveyor trough 18, is designed as a vibration trough.
  • the vibrating trough 18 conveys one after the other in the vertical position of its longitudinal axes x sealing grommets 13 to a receiving position marked 40 in FIG. 6 (cf. also FIG. 7).
  • a receiving position marked 40 in FIG. 6 cf. also FIG. 7
  • FIG. 7 in order to avoid overloading the drawing, only the longitudinal central axis x of the spout 13 is entered.
  • an approximately part-circular centering mandrel 41 can penetrate from below into the central opening 24 of the nozzle 13 as soon as the centering mandrel 41 is moved in the pivoting direction g.
  • a jaw tool 42 which can be moved along the horizontal direction (double arrow a) is already in alignment with the discharge opening 43 of a guide channel 44 which is curved in a partially circular manner in accordance with the curvature of the centering mandrel 41.
  • the centering mandrel 41 which projects freely in the form of a part circle, pushes the nozzle 13 through this guide channel 44 up to the position according to FIG. 8 against a stop 54, after which the nozzle 13 is gripped by the jaw tool 42.
  • the stop 54 serves for the exact centering of the position with regard to the jaw tool 42.
  • the centering mandrel 41 can now be pivoted back into its starting position according to FIG. 7.
  • the centering pin 41 is designed in the manner of a double lever and can be rotated about an axis of rotation 45.
  • the drive end 46 of the centering mandrel 41 can be moved back and forth by means of the piston rod 47 of a pneumatic piston-cylinder unit 48.
  • the jaw tool 42 can be moved back and forth along a linear guide 49 in the horizontal direction along the movement arrow a.
  • the jaw tool 42 is still movable along an inclined linear guide 50, so that the jaw tool 42 according to FIG. 9 can be aligned with the insertion direction E of a line end K.
  • the device according to FIGS. 5 to 9 is particularly intended for line ends K which still carry their insulation jacket during their grommet assembly. Since the insulation jacket gives the line ends K a certain additional rigidity, a sleeve tool 20, which is shown in connection with the embodiment 10A according to FIGS. 1 to 5, is not absolutely necessary.
  • an insertion device which has an upper, spatially fixed jaw 51 and a lower jaw 52 which can be moved up and down relative to the jaw 51 along the movement arrow h.
  • the lower and upper jaw are now able to temporarily hold the line end K between them so that they cannot move.
  • the insertion process is carried out in two partial strokes along the direction E.
  • the starting position before each partial stroke indicated by a broken line of the jaw arrangement 51, 52.
  • the direction of movement of the jaw arrangement 51, 52 is designated by m in FIG. 9.
