Definitions

  • the present invention relates to a device for monitoring the contact pressure of a tachometer or drive roller which can be displaced radially to the coil axis according to the preamble of patent claim 1.
  • the aim is for the drive or tachometer roller to be pressed onto a coil mandrel with a force which remains essentially constant over the entire package structure, or for several coils on a coil mandrel in order to bring about a uniform package structure.
  • the contact pressure can be kept within the desired limits by known means, with small differences in parallelism with increasing bobbin packing between the bobbin mandrel and the shaft of the tachometer roller, no major influences on the quality of the Have coil.
  • a known device of this type US Pat. No.
  • the invention seeks to remedy this.
  • the invention as characterized in the claims, solves the problem of creating a device for monitoring the contact pressure of the tachometer or drive roller, by means of which the contact pressure can be determined exactly at any time and whose signals can be used for controlling the contact pressure if required.
  • the interposition of a force measuring element directly between the tachometer shaft and the holding means carrying the tachometer shaft enables extremely precise detection of changes in the contact pressure of the tachometer roller on the surface of the coil package.
  • minimal deviations with regard to the parallelism of the coil and speedometer shaft axes can already be determined and the resulting signal can be used for corrective measures.
  • the influence on the control of the contact pressure can be minimized by using a low-displacement measuring element.
  • the force measuring elements placed on the shaft ends or in the area of the shaft ends advantageously enable scanning at the next possible location to the coil surface. Deflection of the bracket and / or other parts have no influence on the measurement result.
  • force measuring bearings which are placed directly on the speedometer cable, can be used to carry out the force measurement in a cost-effective manner using commercially available elements. Additional force measuring elements inserted between the ends of the tachometer shaft enable the contact pressure to be recorded and controlled in the central area of the tachometer roller. In this way, the contact pressure on each individual coil can also be monitored if a plurality of coils are simultaneously built next to one another on a coil mandrel.
  • the signals from the force measuring devices can be displayed and processed individually or as a sum. The contact pressure is thus created to influence the spool parallel to its axis of rotation or to make corrections in the event of non-parallelism.
  • the signals from the pressure measuring elements can advantageously be used for speed monitoring as a function of the contact pressure.
  • a cantilevered bobbin 5 with a sleeve 7 arranged thereon and a yarn package 9 is visible.
  • a tachometer roller 11 is rotatably mounted in a fork-shaped holding means 13 above the coil pack 9.
  • the axes of rotation A and B of the spindles 5 and 4 of the tachometer roller 11 run essentially parallel.
  • the holding means 13 for the speedometer roller 11 is in the present example by means of a cylindrical pin 15 in a bore 17 in a vertical guide grooves 19th slidably arranged carrier 21 mounted.
  • connection between the pin 15 and the bore 17 can be made by means of O-rings 23 inserted into the annular space.
  • Linear drives for example pneumatic cylinders 25, are used on the end wall 1 of the winding machine 3 for vertical displacement of the carrier 21.
  • the pneumatic cylinders 25 are attached on the one hand to a support 27 on the machine housing and on the other hand to a bracket 29 on the carrier 21.
  • the holding means 13 can be connected laterally to a further linear drive 31, for example a pneumatic cylinder, which enables the axis of rotation B, the tachometer roller 11, to be pivoted with respect to the axis of rotation A of the coil mandrel 5.
  • a further linear drive 31 for example a pneumatic cylinder, which enables the axis of rotation B, the tachometer roller 11, to be pivoted with respect to the axis of rotation A of the coil mandrel 5.
  • a displacement of the holding means 13 against the spool mandrel 5 means could also be used which shift the spool mandrel 5 against the speedometer roller 11.
  • the force measuring elements 39 and 41 can be designed as force measuring bearings, or pressure-sensitive measuring elements can be inserted between the conventional bearings of the tachometer roller 11.
  • the two force measuring elements 39 and 41 are connected to display means 43, which individually indicate the instantaneous forces at the ends 33 and 35 of the speedometer roller 11.
  • a display means 45 can also be provided, which displays the sum of the forces at the measuring points.
  • An evaluation means 47 compares the incoming actual values with the target values.
  • a memory electronics 49 can also be connected to the evaluation means 47, which stores or prints the measured values.
  • the signals of the force measuring devices 39 and 41 for actuating the linear drives 25, which can adjust the radial distance of the tachometer roller 11 from the coil axis A, are used.
  • a control circuit 51 triggers the actuation of the linear drives.
  • the axis B of the tachometer roller can be adjusted with respect to the axis A of the coil, in particular if, due to a heavy coil package 9, the coil mandrel 5 is down at its free end slack and a correction of the axis position is necessary. Furthermore, the speed of the coil 9 can also be adapted to the measured conditions. Corresponding signals are fed to the control device via a control device 55 and a setpoint generator 53.
  • the holding means 13 for the speedometer roller 11 is not mounted directly in the carrier 21, which is vertically displaceable on the end wall 1 of the winding machine.
  • an intermediate carrier 57 is inserted, which contains the bore 17, in which the cylindrical pin 15 of the holding means 13 engages and is held elastically by means of O-rings 23.
  • the upper side of the carrier 57 is connected to the carrier 21 by means of force measuring elements 39 and 41; on its lower edge, the connection between the intermediate carrier 57 and the carrier 21 consists of a thin elastic sheet 59.
  • the tachometer roller about the axis C of the cylindrical pin 15 can correct the deviation.
  • the total force between the coil 9 and the tachometer roller 11 is measured by the force measuring elements 39 and 41.
  • the masses of the intermediate carrier 57 as well as the holding means 13 and the speedometer roller 11 must be taken into account during the measurement.
  • the evaluation or utilization of the measured data on the measuring members 39 and 41 can be carried out analogously to that in FIGS. 2 to 4 described manner.
  • conventional, commercially available pressure measuring elements are used as measuring elements 39, 41.
  • FIG. 7 which, with the exception of the position of the axis C of the cylindrical pivot pin 15, corresponds to the suspension arrangement according to FIGS. 1 to 4, it has an L-shaped support 21, in the vertical leg of which the bore 17 for the pin 15 is embedded.
  • the force is measured at the ends 33, 35 of the tachometer roller by means of annular force measuring elements 39, 41, which can be part of the bearings that support the tachometer shaft 37.
