Definitions

  • the present invention relates to a device for compensating the sag of the bobbin mandrel of a winder according to the preamble of patent claim 1.
  • the spindles for receiving the spool are often mounted elastically in the machine frame.
  • a tachometer or drive roller is arranged above the coil mandrel and can be pressed linearly on the surface of the coil. With increasing coil weight and consequently greater sag of the coil mandrel, the contact pressure of the tachometer roller is increasingly reduced towards the flying end.
  • the object of the present invention is to provide a device which ensures a pivoting movement of the speedometer or drive roller.
  • the device according to the invention makes it possible, in a cost-effective manner, to create a pivot bearing for the speedometer roller, which enables a pivoting movement both in both directions of rotation about the pivot axis and radially to the pivot axis.
  • the O-rings which accommodate both the tangential and radial deflections of the yoke carrying the tachometer roller, allow the device to be operated completely maintenance-free for years.
  • the characteristic of the adaptation of the tachometer roller to the inclination of the coil mandrel can be influenced by correspondingly varying the number and the preload of the O-rings.
  • FIG. 1 shows an automatic winder 1 with two bobbins 5 mounted on a turret, a thread laying device 6 of known construction and the machine housing which contains the drive motors for the bobbin 5, the laying device 6 and the other units and parts of the control.
  • the turret carrying the two mandrels 5 is not shown and has a known construction.
  • the two bobbin mandrels 5 are overhung, which means that empty bobbins can be loaded or the full bobbins 3 can be removed by hand or by an automatic doffer.
  • FIG. 2 only shows the winding mandrel 5 with two spools 3, the tachometer or drive roller 7 and the housing wall 9 facing the winding unit for the sake of clarity.
  • the winding mandrel 5 is mounted in the housing of the winding machine 1 and connected to a drive. The end of the winding mandrel 5 facing away from the winding machine 1 is not supported. It is therefore a "flying" storage.
  • the two coils 3 are placed on the spool mandrel 5 and held in a rotationally fixed manner by the mandrel 5. Above the coils 3, essentially perpendicularly above the coil mandrel axis and parallel to the latter, the tachometer or drive roller 7 is rotatably mounted at both ends in a carrying device, in short yoke 11.
  • a drive 13 can also be attached to the yoke 11 and connected to the speedometer roller 7 by means of a transmission belt 15.
  • the yoke 11 is connected to the winding machine 1 by means of a preferably cylindrical pin 17 via a carrier 19.
  • the carrier 19 also has a preferably cylindrical bore 21, the diameter of which is larger than the diameter of the pin 17.
  • the connection between the pin 17 and the carrier 19 is made by two O-rings 23 which are placed on the pin 17 at an axial distance and are in contact with the bore 21.
  • O-rings with a round cross-section it is of course also possible to use rubber-elastic rings with others, for example oval ones or rectangular, cross-section can be used, or an insert made of rubber-elastic material can fill the entire space between the surface of the pin 17 and the bore 21 (the latter variant not shown).
  • the carrier 19 is vertically displaceable on the housing 9 of the winding machine 1, for example in a dovetail groove or the like.
  • the rotation of the pin 17 is in the range of angular minutes.
  • the tangential displacement of the surface of the pin 17 with respect to the surface of the bore 21 is absorbed by the elasticity of the O-rings 23 forming the connection between the two surfaces.
