Definitions

  • the present invention relates to a device for winding a thread according to the preamble of claim I.
  • Such a device is already known from European Patent 0 063 690.
  • the device shown in this shows that the rubbing and scouring of the friction roller on the yarn package is greatly reduced and a wound yarn of uniform yarn tension is obtained.
  • jamming of the rotary elements on the side may occur with the central rotary element.
  • the main cause of such jamming is that contamination can occur between the middle element and the side elements as a result of fibers, yarn particles, dust and the like. If jamming occurs, one of these side elements rotates at too high or too low a rotation speed and forces the other side element, since the two are firmly coupled together, to rotate at too low or too high a rotation speed. In such circumstances, the rubbing roller exerts a strong abrasive effect on the bobbin to be wound, which can damage the yarn.
  • FIG. 1 shows a longitudinal section of a friction roller according to the invention.
  • the friction roller II shown in the figure has a drive shaft 12 with a longitudinal axis 13. On the shaft 12 with a fixed rotation element 14 is attached. Subsequent to each end of the same there are two lateral rotation elements 15 and 16. Each of the latter is carried by a rotary bearing 17 or 18 and rotatable about the drive shaft 12.
  • the middle rotation element 14 has two hollow cylinders 19, 20 which are firmly connected to one another by a web 21. All of these parts 15 to 21 are arranged coaxially to the shaft 12.
  • the web 21 has the shape of a circular ring perpendicular to the axis 13.
  • the outer hollow cylinder 19 is relatively long and thereby covers part of the rotary elements 15 and 16, respectively.
  • An annular contact body 22 is rotationally connected to the element 15, but can be displaced along this in the axial direction. It is guided through its contact with the inner wall of the cylindrical part 24 of the element 15. By means of a compression spring 26, it is biased against the central plane 28 separating the friction roller II in two halves.
  • a contact body 23 and a compression spring 27 are present on the cylindrical part 25 of the element 16, which parts perform a function analogous to the parts 22, 24, 26.
  • three guides 29 are provided for three rolling bodies designed as balls, of which only one ball 30 attached in a guide 29 is visible in the figure.
  • the center points of the balls are located on a circle (not shown) coaxial to the shaft 12 at equal distances from one another.
  • the diameter of this circle is the same as the average diameters of the annular contact bodies 22, 23.
  • the mean diameter is understood to mean the diameter of the circles which are formed by the center points of the cross sections of the bodies 22 and 23, respectively.
  • the contact bodies 22, 23 are thus biased against the rolling elements by the springs 26, 27.
  • two grooves 31, 32 are provided in the drive shaft 12. Screws 35, 36 are provided in the inner rings 33, 34 of the rotary bearings 17, 18, which serve to fix the position of the bearings 17, 18 in the axial direction.
  • the seals 37, 38 serve to prevent dust from entering the bearings 17, 18.
  • three rolling elements are provided.
  • the advantage of this embodiment is that the contact bodies 22, 23 rest evenly and thus stably on all three rolling bodies 30. It is obvious that more than three rolling elements 30 can also be present.
  • the contact body 22, 23 are guided through the cylindrical parts 24, 25 and prevent the same from tilting, can NEN only two rolling elements or, in extreme cases, only one can be provided.
  • Balls 30 are provided as rolling elements according to the example shown. Instead of such, cylindrical or conical rolling elements can also be provided, the axes of rotation of which lie radially with respect to the drive shaft 12 (as is also the case with the spherical rolling elements 30 shown).
  • the covering of the parts of the elements 15, 16 directed against the element 14 by the outer hollow cylinder 19 has the advantage that dust particles, fibers and the like are much less inside the friction roller II, i.e. get into their coupling part.
  • This covering thus forms an advantageous measure in order to achieve better protection against contamination of the elements 15, 16.
  • the contamination can be reduced to a greater extent by the provision of ribs moving the dirt out in the space between the hollow cylinder 19 and the part of the elements 15, 16 covered by it.
