Definitions

  • the invention relates to a device for cable assembly of flat ribbon conductors with plugs, in particular insulation displacement contact elements, equipped housings in a contacting station, which is constructed in series in the processing sequence from a flat ribbon conductor supply device, a line feed device, a cutting station and a transverse transport device that detects the cut lines the transport of the ribbon cable to the contacting station, the housing can be fed from the other side with a feed device, and to the subsequent processing stations, with vertically movable clamping pliers being arranged on both sides of the transverse transport direction running along the individual processing stations in order to hold the cut-to-length lines on the respective ones To fix machining stations.
  • Such a cable assembly device is known from the applicant's own European patent application 95 11 1726.6.
  • the transverse transport device consists of two opposing tongs running along the individual processing stations, which are able to move back and forth synchronously horizontally to transport a cut flat ribbon conductor from processing station to processing station.
  • the pliers also take on the function of fixing the cut-to-length lines at the respective processing stations.
  • this transverse transport device enables reliable transport of the cut-to-length lines from processing station to processing station, however, in Experience has shown that the large dimensions, the high center of gravity and the large masses of the two tongs cause the unsteady running of the machine in the clocked operation of the transverse transport device due to the large acceleration and braking forces.
  • the large and difficult to move brackets also limit the clock speed of the cross conveyor.
  • the invention is based on the object of further developing a cable assembly device of the type described above in such a way that the transverse transport device enables higher cycle and thus processing speeds without the transverse transport device causing the cable assembly device to run uneasily.
  • the transverse transport device consists of at least one transport carriage with consecutively arranged thereon transport jaws in that the transport carriages arranged between the clamping tongs back in front of the individual processing stations and is movable and hergetaktet.
  • the subdivision of the cable assembly device into a transverse transport device for transporting the cut lines along the processing stations and in clamping pliers for fixing the cut lines at the respective processing stations resulted in a considerable reduction in the dimensions and masses of the transverse transport device.
  • the transverse transport device designed according to the invention is now only responsible for transporting the cut-to-length lines from one processing station to the next, while the fixation at the processing stations is carried out by the clamping pliers known from the prior art. Since a transverse transport device designed in this way can be made much smaller and lighter, it can also be operated at higher cycle speeds without the acceleration and braking forces which occur causing the machine to run unevenly.
  • the number of consecutively arranged on each transport slide corresponds Transport jaws at least the number of processing stations along which the transverse transport device can be moved back and forth in a clocked manner. In this way, it is ensured that each work cycle of the transverse transport device supplies each of the processing stations arranged one behind the other with corresponding lines.
  • the transport jaws arranged on the transport slides are each formed as pairs of jaws consisting of a fixed jaw part and a movable jaw part.
  • the movable jaw parts can be arranged tangentially on the circumferential surface of a gearwheel, which is arranged within the transport carriage and can be driven via a toothed rack which couples all the gearwheels for the movable jaw parts of a transport carriage with one another.
  • the use of a toothed rack connecting all the gearwheels to one another ensures that all movable jaw parts of a transport carriage arranged on the gearwheels are driven uniformly and simultaneously.
  • the movable jaw parts are preferably made in two parts from a flexible material, preferably spring steel.
  • This resilient two-part design of the movable jaw parts has the advantage that even with the simultaneous transport of two cut-to-length lines or when there are large differences in thickness of the ribbon cable, approximately the same pressure can be applied to the line to be transported by the transport jaws.
  • the rack for driving the gearwheels equipped with the movable jaw parts and the drive for each transport slide is preferably carried out by means of reciprocating pneumatic drives.
  • a compression spring preferably designed as a helical spring, is arranged on the rack in the region of each transport jaw.
  • the fixed jaw parts of the transport jaws can be arranged interchangeably in the transport carriage in order to adapt these jaw parts to the accommodation of different cable thicknesses.
  • the machine is made up of various devices connected one behind the other, corresponding to the processing sequence, which on the one hand includes the supply of ribbon cables to a contacting station and on the other hand the delivery of connectors to this contacting station, in which the machine equips the cables with the connectors on one or both sides .
  • a line supply device 1 which has ribbon conductor 2 rolled up in the form of one or two cable drums, a cable backstop 3 for the ribbon conductor 2 to support a cable feed device 4, a cutting station 5 and, in a coaxial line, an axially movable cable pulling pliers 6 for pulling them out are connected in series the desired cable length.
  • the ribbon conductor 2 wound in the line supply 1 are guided through the cable backstop 3, so that a loop is first formed to pull in the selected length of ribbon with the cable drum drive and then the line feed device 4 is activated, which transports the selected ribbon length to the cable pulling pliers 6.
  • the cable backstop 3 prevents the flat strip 2 drawn in in this way from running back to the unwinding side.
  • the cable pulling pliers 6 are arranged to be axially movable on a rail, as shown by the double arrow in FIG. 1, and move against a stop on the left.
  • a gripping tool of the cable pulling pliers 6 accepts the supplied flat ribbon conductor 2 and pulls it in its backward movement up to the position shown in FIG. 1.
  • the ribbon cable 2 is thus drawn into the actual work area of the machine.
  • the line feed device 4 conveys flat ribbon cables 2, a loop being formed in the work space.
  • the desired processing length is now applied to ribbon conductor 2 in the working area of the machine.
  • the individual processing stations of the machine extend transversely to the described course of the supply devices 1, 3, 4, 5 and 6 for the ribbon conductor 2, again arranged one behind the other in the processing direction. These are linked to one another by a transverse transport device 7.
  • This transverse transport device 7 is arranged between clamping tongs 8 which extend on both sides of the transverse transport direction running along the individual processing stations and which are movable vertically and serve to fix the cut-to-length flat conductor 2 at the respective processing stations.
  • the transverse transport device 7 consists of two transport carriages 9, which are connected to one another via a cross member 10.
  • the crossbeam 10 can be omitted for cable lengths of 82 to 500 mm, since due to the bending elasticity of these lines, a slight offset of the transport carriages 9 to one another does not damage the line.
  • the use of only one transport carriage 9 is sufficient.
  • each transport jaw 11 consists of a fixed jaw part 11a arranged on the upper side of the transport carriage 9 and a movable jaw part 11b.
  • the movable jaw part 11b is arranged tangentially on the circumferential surface of a gearwheel 12 arranged inside the transport carriage 9.
  • the fixed jaw part 11a which is provided with a profiled transport surface 11c, is interchangeably arranged on the transport carriage 9.
  • the fixed jaw part 11a has on the side opposite the transport surface 11c a groove 13 provided with two undercuts, by means of which the fixed jaw part 11a can be pushed onto a sliding block 14 or the like.
  • each gear wheel 12 of a transport carriage 9 is in engagement with a toothed rack 15, the toothed racks 15 being firmly connected to one another, so that all toothed wheels 12 of a transport carriage 9 are activated simultaneously when a toothed rack 15 moves.
  • a rack drive 16 which is designed as a pneumatic drive.
  • the back and forth movement of the toothed rack 15 via the toothed rack drive 16 causes a rotation of the toothed wheel 12 and thus an adjustment of the movable jaw part 11b.
  • 3a the open position of the transport jaw 11 is shown, in which the movable jaw part 11b is pivoted back so far into the interior of the transport carriage 9 that it comes to lie below the surface 9a of the transport carriage 9.
  • the piston rod 16a of the rack and pinion drive 16 is extended to the left, as a result of which the rack 15 which is in engagement with the gearwheel 12 is also moved to the left.
  • This movement of the rack 15 causes a rotation of the gear 12 and thus a pivoting of the movable jaw part 11b in the closed transport position, as shown in Fig. 3b.
  • a compression spring designed as a helical spring 17 is arranged on the rack 15.
  • the transport slide 9 has a slide drive 18, by means of which the entire transport slide 9 can be moved to and fro in front of the individual processing stations.
  • the ribbon conductors 2 which have been pulled off the conductor storage device 1 and held by the cable pulling pliers 6 are cut off in the cutting station 5 after the desired cable length has been set.
  • a stripping and semi-strip station 19 In order to feed the ribbon conductor 2, which has been cut to length and held in this way in the cable pulling pliers 6, to a first processing station, a stripping and semi-strip station 19, the transport slides 9 are moved backwards in the direction indicated by the arrow in FIG. 1 until the one previously in the cable pulling pliers 6 held flat ribbon conductor 2 in the stripping and semi-strip station 19.
  • the flat strip conductor 2 can be stripped on one or both sides and provided with a semi-strip.
  • the semi-strip length is set with interchangeable spacers and the stripping length is determined by a spacer, which is not shown in the drawing.
  • the ribbon conductor 2 previously processed in the stripping and semi-strip station 19 is fed to a subsequent processing station, namely a contacting station 20 which the ribbon cable 2 are equipped with the appropriate housings.
  • the housing feed to the contacting station 20 essentially consists of two vertical stores 21, which contain stacked bar magazines, in which housings are arranged one behind the other in contacting position, and devices 22 for gradually emptying the bar magazines into feed channels 23.
  • the housing feed is designed to be in the contacting station 20 to contact both ends of the ribbon cables 2 delivered there with insulation displacement contact elements in opposite processing.
  • the ribbon conductors 2 previously processed in the contacting station 20 are further transported to a subsequent processing station, which is designed as a control station 25, in which the ribbon conductors 2 equipped with the plug connections in the contacting station 20 are checked for continuity and short circuit.
  • the ribbon conductors 2 previously checked in the control station 25 are fed to a final processing station designed as a cutting station 26.
  • the cutting station 26 disconnects the ribbon cable 2 on both sides from the plug connectors and sorts the rejects in a disposal station 27.
  • the clamping tongs 8 arranged on both sides along the processing stations 19, 20, 25 and 26 are opened.
  • the clamping tongs 8 are closed in order to fix the ribbon conductor 2 for processing at this processing station.
  • the rack and pinion drive 16 is actuated in order to move the movable jaw part 11b into the open position below the surface 9a of the transport carriage 9.
  • the transport carriage 9 is again moved forward by one working cycle via the carriage drive 18.
  • the rack and pinion drive 16 is actuated in order to close the movable jaw part 11b for transporting the ribbon conductor 2.
  • the carriage drive 18 can be actuated again, so that the above-described transport of the ribbon cable 2 from the cable pulling pliers 6 out to the subsequent processing stations 19, 20, 25 and 26 can be repeated.
  • the transverse transport device 7 consisting of only one or two transport carriages 9 is designed to be very light and small, very fast cycle sequences are possible with a transverse transport device 7 configured in this way. Furthermore, when processing up to 9-pin plug connections, it is possible to process two ribbon cables at each processing station at the same time.
  • the conductor supply device 1 consists of two cable drums.
  • the movable jaw part 11b is made in two parts from a resilient material, preferably spring steel, as can be seen in FIG. 4 is.
  • a cable assembly machine designed in this way is distinguished by the fact that the acceleration and braking forces occurring during the movement of the transverse transport device 7 have no effect on the smooth running of the machine, since the masses of the transport carriage 9 to be accelerated and braked are very small.
