Definitions

  • the invention relates to a device for conveying measured lengths of cable according to the preamble of claim l.
  • Devices of the generic type are known in practice and are used in machines for cable assembly. Such machines are able to cut sections of a predetermined length from an endless cable, to remove the insulation at one or both ends, and at one or both ends with contact elements, e.g. Cable lugs to connect.
  • the cable coming from a cable supply is guided over a straightening device which is arranged in the cable run in front of the measuring wheel.
  • the performance of such a device is measured for the production of longer sections mainly by the maximum feed speed of the cable.
  • Today speeds of 3-4 m / s are common here.
  • the object of the invention is now to provide a device by means of which inadmissible length deviations are avoided even with high deceleration values by forcibly transferring them to the measuring wheel.
  • the measuring location ie the measuring wheel, lies in an area of the cable in which it is acted on in principle in the same way at the same times.
  • the cable itself therefore creates a quasi-rigid drive connection from the feed elements to the measuring wheel; it acts on the measuring wheel as if it were a rigid body.
  • the feed speeds of the pair of feed elements following the measuring wheel are at a constant ratio greater at each drive point in time than on the one provided in front of the measuring wheel Pair of feed elements.
  • the measure also ensures that the cable runs straight on the measuring wheel if there is slippage between the cable and the pair of feed elements in front of the measuring wheel when the cable is decelerated. It has been shown that this measure is effective even at a slightly higher feed rate on the trailing pair of feed elements.
  • the difference in the feed speeds is preferably 0.1-1.0%.
  • a preferred embodiment particularly where the feed speeds are to have a constant ratio, is that all the feed elements are connected to a single drive motor via gear means .
  • the feed elements are designed as rollers in a known manner and a straightening apparatus is connected upstream of the cable run on the inlet side, it is advantageous to determine the diameter of the feed rollers on the inlet side, ie larger in the direction of travel in front of the measuring roller compared to the diameter of the feed rollers on the outlet side. This measure reduces the slip on the inlet side.
  • a diameter on the pair of rollers on the inlet side has proven to be favorable, which is about 1.5-2 diameter of the pair of rollers on the outlet side.
  • A designates a cable run that leads through a machine for assembling cables.
  • a straightening device C, a device for conveying cable D and a processing station E are arranged along the cable run in the running direction of the cable coming from a cable supply B.
  • the processing station E can, for example, be one for cutting and stripping the cable. Further processing stations can follow station E.
  • FIG. 2 which shows an embodiment of the device D according to the invention
  • the direction of the cable in the cable run A is indicated by the arrows 2.
  • the Straightener C not shown, according to FIG. 1, two feed rollers 6 and 8 are arranged on the inlet side of the cable into the device according to the invention, which together form a pair and hold the cable in the operating state in a clamped manner or are in drive connection with it by frictional engagement.
  • the feed rollers 10 and 12 have a smaller diameter than those.
  • a measuring wheel 14 is arranged along the cable path A between the two pairs of feed rollers 6, 8 and 10, 12 and preferably closer to the pair 6, 8, to which the cable is pressed by a counter roller 16.
  • the measuring wheel 14, which is designed with the lowest possible mass, is in drive connection with a pulse generator 18.
  • a drive motor 20 operated with direct current is in drive connection with all feed rollers 6, 8, 10 and 12 via a gear generally designated 22.
  • the gearbox 22 comprises a drive wheel 24 connected rigidly to the motor 20 as well as an output gear 26 for the pair of rollers 6, 8 and a further output gear 28 for the pair of rollers 10, 12.
  • the wheels 24, 26 and 28 are designed as gear wheels, which are wrapped by a common toothed belt 30.
  • the toothed belt 30 is guided over deflection rollers 32 and 34 and is held under tension by a tension roller 36.
  • the driven gear 26 is torsionally rigid with the feed roller 6 and a gear 38 which is also arranged coaxially connected. Via intermediate wheels 40 and 42, the gear 38 is connected to a gear 44 which is arranged coaxially with the feed roller 8 and is connected to the latter in a rotationally rigid manner.
  • the driven gear 28 is in turn connected to an intermediate gear 48 via a gear 46 coaxial therewith, each of the gears 46 and 48 meshing with a drive gear 50 and 52, respectively.
  • the feed rollers l0 and l2 are rigidly connected to the drive wheels 52 and 50, which are each arranged coaxially with the former.
  • the feed rollers 10 and 12 are arranged together with the wheels 52 and 50 so as to be pivotable about the axes of the drive wheels 48 and 46 in a manner not shown.
  • the engagement with the drive wheels remains.
  • the feed roller 8 can be pivoted together with the toothed wheel 44 about the axis of the intermediate wheel 42, likewise while maintaining the drive connection.
  • the pressure roller l6 can be moved to the cable track 2.
  • the pressure roller 16 and the feed roller 8 are in operation under the action of adjustable pressure elements, which are indicated at 54 and 56 by springs. Pressure elements, not shown, also act on the feed rollers l0 and l2.
  • the pairs of feed rollers 6, 8 and 10, 12 are driven by the drive motor 20.
  • Diameter of the pairs of rollers and transmission ratio of the drive wrapped by the toothed belt 30 wheels 26 and 28 are chosen so that the peripheral speed on the rollers l0 and l2 is about 0.5% greater than that on the feed rollers 6 and 8. This has the effect that the cable inserted before the start of operation on the at 58, the distance between the two pairs of rollers is also brought into a stretched state when this has not yet been fully stretched between the pairs of rollers. In further operation, the different drive speeds on the stretched cable are then compensated for by slippage.
  • the measuring wheel 14 derives a measurement result from the stretched cable, by which the latter is both accelerated and decelerated. This result is therefore not influenced by the mass of the measuring wheel or the mass of the cable, since the cable is acted upon in the same way at both ends of the section 58, on which the measuring wheel 14 is located. Both the acceleration and the deceleration of the cable begin simultaneously on both pairs of feed rollers 6, 8 and 10, 12 which limit the distance 58 and also end at the same time. There is a practically rigid drive connection between the measuring wheel and the feed rollers; thanks to its extension, the cable on the measuring wheel behaves like a rigid body.
  • a microprocessor 60 the course of a speed curve is determined according to entered parameters along a path corresponding to a selected cable length.
  • Corresponding digital signals are fed via a digital / analog converter 62 to a controller 64, preferably a four-quadrant controller, at a setpoint input 66.
  • a tachogenerator 70 connected to the motor 20 in a rotationally rigid manner is connected to an actual value input 68 of the controller 64.
  • the controller 64 accordingly controls the motor in a closed control loop.
  • a pulse generator 72 whose signals are fed to the microprocessor 60 together with those of the pulse generator 18, are also connected to the motor 20 in a rotationally rigid manner.
  • the microprocessor 60 continuously compares the signals of the two pulse generators 18 and 72 with the target path calculated from the speed curve and corrects the part of the speed curve that has not yet been traveled accordingly.
  • the device described is able to deliver predetermined lengths of cable with small length deviations despite significantly increased acceleration and deceleration values. It has been shown that accelerations of up to 90 m / sec2 and decelerations of up to 80 m / sec2 can be carried out with great accuracy. Thus, those from engine 20 are also set limits practically reached with the options available today.
  • the device described is economical not only because it allows high maximum speeds and shortening the conveying time with comparatively little effort due to the high acceleration and deceleration values, but also because the small length deviations allow a certain minimum cable length to be conveyed with small tolerances. Compared to known devices, the device according to the invention accordingly also allows cable material to be saved by avoiding excess lengths.
