Definitions

  • the invention relates to a winding machine for winding strand-shaped winding material onto a spool, to which the winding material is fed via a strand guide, with a feed drive for a longitudinally reciprocating traversing movement of the spool and strand guide and with a control device for maintaining a constant run-up angle for exact Laying the turns within each winding layer.
  • a circuit arrangement for controlling the winding of cables which, taking into account the cross-section of the cable and the speed of the memory when forming each new winding position, the relative displacement between the guide member and the memory in the direction of the axis of rotation of the memory controls.
  • the control is carried out in such a way that the cable aimed at the memory is pressed onto the last turn of the cable wound on the memory with a certain run-up angle ⁇ .
  • the speed of the relative axial displacement changes before and after the formation of the next winding layer in such a way that the run-up angle a tends towards the value zero before the formation of the new winding position and that after the formation of the new winding position the run-up angle a increases to its desired value.
  • a cable winding machine with a drum rotatably mounted on spindles for winding an electrical cable has become known, the cable is guided by a wire guide.
  • a layer monitor who reciprocates with the wire guide monitors both the start of a new winding layer on the drum flanges and the application of the winding itself within one layer in order to control deceleration or acceleration of the wire guide.
  • a position sensor is used to measure the distance of the position monitor from a side beam. The number of pulses generated by the position sensor when the position monitor is shifted is compared with the reference pulses generated by a pulse generator which are generated when the wire guide is shifted at a constant speed.
  • the deceleration or acceleration of the wire guide can thus be controlled in order to reduce the wire guide speed on the route of the last turns, if necessary. In this case too, it is a kind of follow-up control of the actual position of the wire guide or the run-on point with the same disadvantages as the arrangement according to FR-A 2 263 970.
  • the invention has for its object to eliminate fluctuations in the run-up angle during the formation of the respective winding position in a winding machine of the generic type in which the distance or contact pressure between adjacent turns of a winding layer is determined exclusively by the relative movement between the coil and the strand guide.
  • the control device from a first measuring device, which detects the position of the last wound winding at a measuring point lying at a certain coil rotation angle in front of the winding material take-up point, from a second measuring device for detecting the the respective traversing position of the spool and strand guide and consists of a computer which calculates the relative position from the measurement data of both measuring devices and commands the feed drive which the spool and the strand guide must have reached after maintaining the spool rotation angle to maintain the run-up angle.
  • the position of the later run-up point is thus always determined in advance and the relative movement between the spool and strand guide is controlled in the meantime in such a way that the desired run-up angle is always maintained when the previously determined run-up point arrives at the actual point of winding up.
  • the traversing drive is switched on accordingly, so that after the 60 ° spool has been rotated, the relative position of the spool and strand guide is again the same as at the earlier measurement time. Since this approach always detects the run-up point as a function of the last wound winding, there are no total errors when calculating the traversing movements.
  • this type of early control of the traversing drive provides high reliability and laying accuracy and is an essential step in the general effort to create fully automatic winding machines that no longer require monitoring and corrective actions by an operator.
  • the first measuring device consists of a laterally movable sensing element which laterally scans the last wound turn, which, depending on its deflection, has a measured value for determining the position of the turn relative to the strand guide at a certain angle of rotation of the spool after it Sampling position (point of contact) delivers.
  • the first measuring device can consist of a television camera arranged outside the winding space of the coil and directed tangentially to the uppermost winding, which monitors the migration of the front end of the layer that has just been wound.
  • the output signal of this television camera is evaluated in such a way that the position of the end face of the winding layer with respect to a fixed coordinate parallel to the coil axis is specified.
  • the current position of the spool is also recorded on this fixed coordinate if the spool carries out the traversing movement, or else the current position of the strand guide if it carries out the traversing movement.
  • the relative position that the coil and strand guide must have when the measured point of the last turn has reached the winding material take-up point can then be calculated together with the known diameter of the winding material.
  • the measurement of the last turn of a layer can be carried out, for example, 10 times per coil revolution; Accordingly, there are 10 set positions of the winder (or strand leader) per coil revolution, which after the corresponding part of a coil revolution, i.e. depending on how far the measuring point is from the run-up point, should be reached by the traversing drive.
  • a retention angle to be set can of course also be taken into account.
  • the optimal retention angle which depends on the material to be wound, can be set by programming the computer.
  • the last turn is used as a template for the next turn.
  • the temporal separation of the measuring point from the run-up point also has the great advantage that the traversing movements, which are associated with inertia, can be initiated in good time and even speed-dependent via the computer, so that undesired climbing of the winding material can be avoided with certainty.
  • the first measuring device can be composed of distance sensors, for example those arranged radially to the coil and arranged outside the winding space of the coil. B. ultrasonic sensors exist.
  • the first measuring device consists of a television camera directed radially onto the spool and a headlamp which is inclined in relation thereto and which illuminates the spool with a band of light extending over the winding material run-up area, the television camera and headlamp outside the winding space of the spool are arranged.
  • a variant of the subject of the invention is equally based on a winding machine for winding strand-shaped winding material onto a spool, to which the winding material is fed via a strand guide, with a feed drive for a longitudinally reciprocating traversing movement of the spool and strand guide and with a control device for maintenance a constant run-up angle for exact laying of the turns within each winding position, which control device also has a first measuring device that measures the run-up angle of the winding material, and provides that the control device also has a second measuring device for detecting the respective traversing position of the coil and strand guide and a computer , which calculates the relative position from the measurement data of both measuring devices and commands the feed drive to move the bobbin and the strand guide to the Au after rotating the bobbin by the aforementioned bobbin rotation angle maintenance of the run-up angle must have been reached.
  • the second measuring device can consist of a pulse tachometer which runs with the laying drive and quasi scales the path of the laying drive.
  • the traversing movement can take place in a known manner by an axial movement of the strand guide along the fixed bobbin.
  • the strand guide For other winding material, e.g. thicker electrical cables, on the other hand, it is necessary for the strand guide to remain stationary and for the spool to perform the traversing movement.
  • the invention can be used in the same way for both types.
  • the spool executes the traversing movement at a fixed predetermined speed and that the strand guide is also adjustable in the traversing direction, but only executes the correcting movements determined by the reversing device according to the invention.
  • Such an embodiment proves to be very advantageous in particular when winding at very high speeds.
  • FIGS. 1 to 3 illustrate a winding machine with a four-legged frame 2 that can be moved on rollers 1, on the upper part of which two quill arms 3, 4 are suspended, on the lower quills 5, 6 of which a coil 7 with flanges 8 is received.
  • a coil-shaped winding material 10 is fed to the coil 7 via a stationary strand guide 9, which is to be wound up with closely adjacent turns and with winding layers lying exactly one above the other.
  • the winding material take-up point 11 travels back and forth between the coil flanges 8, the material to be wound running to achieve a close contact of adjacent windings with a constant run-up angle a on the coil.
  • the winder in the exemplary embodiment is moved back and forth in front of the strand guide 9 by means of a feed drive 12, a measuring device 13 designed as a pulse tachometer determining the position of the winding machine or the coil 7 relative to a stationary coordinate parallel to the coil axis 14 determined and delivered to a computer 15 arranged on the strand guide 9 in the exemplary embodiment.
  • a measuring device 13 designed as a pulse tachometer determining the position of the winding machine or the coil 7 relative to a stationary coordinate parallel to the coil axis 14 determined and delivered to a computer 15 arranged on the strand guide 9 in the exemplary embodiment.
  • the computer 15 also contains values from a further measuring device 16 for the respective position of the last wound winding 17, this measurement taking place at a point preceding the actual winding material take-up point 11 by a certain angle of rotation, here 180 °.
  • the measuring device 16 is a television camera directed tangentially onto the coil winding, which is opposed by an optical contrast surface 18 on the opposite side.
  • the measuring device 16 is preferably actuated in cycles and, for example, supplies a signal for the position of the winding flank 17a of the last wound winding 17 at the position shifted by 180 ° with respect to the actual run-up point 11, for example ten or twenty times per coil revolution.
  • the computer 15 calculates the relative position which must exist between the coil 7 and the strand guide 9 after a further 180 ° coil rotation so that the desired run-up angle a is maintained.
  • the control of the traversing movement can take place very precisely, so that the traversing movement can closely follow the irregular course of the individual turns shown in an enlarged representation in FIG.
  • the risk that the material to be wound unintentionally climbs to a next higher winding position at such a winding jump Z is excluded in the type of control according to the invention.
  • FIG. 5 as in FIGS. 7, 9 and 13, which will be described later, the left-hand coil flange 8 is omitted.
  • FIGS. 6 and 7 illustrate an exemplary embodiment in which the device for detecting the position of the last wound winding consists of distance sensors 19 directed radially to the coil, which may be ultrasonic sensors, for example.
  • FIGS. 8 and 9 show a measuring device which consists of a television camera 20 which is oriented approximately radially onto the coil and of a headlight 21 which is inclined in relation thereto and which illuminates the coil 7 over its entire length with a light band 22a, 22b. Due to the different alignment device of headlamp 21 and camera 20 jumps the light band for the camera at the boundary between two superimposed winding layers and can therefore consequently be followed by the camera 20 exactly the build-up and migration of the end face of the upper winding layer.
  • FIGS. 10 and 11 show a mechanical feeler 23, which bears against a point on the side surface of the last wound turn 17a, which is approximately 90 ° ahead of the winding material take-up point 11.
  • the feeler 23 is displaceable on a guide 24 parallel to the coil axis.
  • the feeler 23 When approaching, for example, the slope of the jump Z of a turn, the feeler 23 is temporarily shifted in the direction of the guide 24, but this movement is measured and used to calculate and trigger a drive command to the traversing drive in such a way that the coil again after 90 ° rotation is in the same relative position to the strand guide and thus the sensing element 23 could return to the basic position shown.
  • the position of the last wound turn is measured indirectly from the inclined position or the retention angle of the incoming winding material strand 10 by means of a television camera 25 and delivered to the computer 26.
  • the television camera is directed obliquely upwards and is opposed by a contrasting field 27 or light strip for easier detection of the winding strand.
  • the run-up angle changes by a certain amount.
  • the computer stores this information and controls the traversing drive in such a way that after a further turn of the spool, the traversing position is adjusted by a winding material diameter.
  • the run-up angle is continuously detected by a mechanical scanning device 28 with a sensing roller 29.
  • the evaluation takes place here in the same way as in the previous exemplary embodiment according to FIG. 12.
