Definitions

  • the present invention relates to a tube changing device on a ring spinning or ring twisting machine with a conveyor belt, which has a plurality of tube holders used for mounting tubes, the mutual spacing of which is equal to the spindle pitch, and which extends horizontally in the longitudinal direction of the machine.
  • This type of sleeve change has the disadvantage that a relatively large amount of space is required on the machine between the spindle bearings and the conveyor belt. This has an effect in particular in that the spindle bearings cannot be made long enough. On the other hand, the spindle banks must be reduced in size, which affects their strength.
  • the present invention is intended to avoid the disadvantages mentioned above.
  • This is characterized in that a support means running in the longitudinal direction of the machine is provided, which is located in front of the sleeves attached to the sleeve holders and serves as a system for them.
  • 11 denotes the left side wall and 12 a rear wall of the machine frame.
  • a spindle bench 13 is fastened to the wall 12 and carries spindle bearings 14 with spindles 15.
  • the spindles 15 can be driven via drive rollers 16.
  • Each is provided with an upper spindle part 17 (FIG. 2) and a sleeve 18 is placed on each upper spindle part 17. The spun threads are wound onto the latter during machine operation.
  • a guide 21 is located below the spindle bank 13, also fastened to the rear wall 12 (for the sake of clarity, this guide 21 is not shown in FIG. 1). It serves to guide a conveyor belt 22 on which sleeve holders 23 are fastened .
  • the mutual distance between adjacent sleeve holders 23 is the same as the distance between adjacent spindles 15, ie the spindle pitch.
  • the conveyor belt 22 is held by the guide 21 in a position in which it is positioned in an inclined manner in the forward direction, ie to the left in FIG. 2, with respect to the machine.
  • a rod 25 forming a support means extends in the longitudinal direction of the spinning or twisting machine. It is fastened to rods 26 arranged at a distance from one another and serves to support the sleeves 24. The rods 26 in turn are fastened to the guide 21.
  • individual support columns 27 are provided, distributed over the length of the machine. Only one such support column 27 is visible in the drawing. Like the other columns, not shown, this is pivotally mounted in a base 28. It can be swiveled between the position drawn with solid lines and the position drawn with dashed lines.
  • Each of the support columns 27 has a carrier 31. The latter are displaceable in height along the support columns 27.
  • the carriers 31 carry a pulling bar 32 which extends in the longitudinal direction of the machine and to which pins 33 are attached at intervals corresponding to the spindle pitch, which are in register with the holes in the full sleeves 18.
  • a deformable hose 34 runs between the pins 33 and the vertical rear wall of the stripping bar 32. This can be supplied with air of variable pressure.
  • the stripping bar 32 can, together with the supports 31, be moved up and down along the support columns 27.
  • a guide 20 for a conveyor belt 22 and a sleeve 24 are shown.
  • An elongated, areal element 36 which extends in the longitudinal direction of the machine (perpendicular to the plane of the drawing), serves as a support means and support for the sleeves 24 and at the same time forms the front wall 39 of a coil and sleeve channel 37, in which the conveyor belt 22 is located.
  • the sleeves 18 When the sleeves 18 are fully wound with threads during operation of the ring spinning or ring twisting machine, they are removed and replaced by empty sleeves 24.
  • the pressure inside the hose 34 is kept low and the stripping bar 32 is moved down until the pins 33 are immersed in the bores of the full sleeves 18.
  • the hose 34 thus lies against the wall of the full sleeves 18. If the pressure inside the hose 34 is increased, the full sleeves 18 are held firmly by the latter and the pins 33.
  • the puller bar 32 By lifting the puller bar 32, the full sleeves 18 are now lifted off the upper spindle parts 17, then the support columns 27 are pivoted into the position shown in dashed lines and the puller bar 32 is then lowered until the full sleeves 18 can be dropped onto the belt 22.
  • the conveyor belt 22 has previously been positioned in its longitudinal direction in such a way that the full sleeves 18 enter the spaces between the empty sleeves 24.
  • the conveyor belt 22 is first shifted by half a spindle pitch.
  • the pins 33 enter the bores of the sleeves 24.
  • the latter are now raised in a manner corresponding to the method just described and are brought into their working position on the upper spindle parts 17.
  • the full sleeves 18 are carried away by the conveyor belt 22.
  • the oblique position of the sleeves 24 makes it possible to keep the distance between the guide 21 or the conveyor belt 22 and the spindle bench 13 small, so that space is saved in an area of the machine that is important for the operation .
  • the spindle bench can be given a U-shaped cross section, which increases its mechanical strength considerably.
  • the inclined position of the conveyor belt 22 shown thus has significant advantages. However, it also has a disadvantage: if one of the sleeves 24 for any reason, e.g. B.
  • a support means is shown, which is formed by an elongated, in the longitudinal direction of the machine extending, sheet-like element 36, the cross section, i. H. whose profile is of a curved shape. This gives the element 36 sufficient strength to ensure the exact inclination of the sleeves 24.
  • the element 36 is fastened to the tape guide 20 and forms the front wall 39 of a spool and sleeve channel 37.
  • the support means serving for the exact positioning of the sleeves 24 is designed as an elongated, planar element 38 comprising an arcuate cross section.
  • the choice of the arcuate cross section serves to increase the strength of the element 38.
  • the latter is fastened to the coil and sleeve channel 37 in this example.
  • the support means can also be designed as a tubular rod.
  • a round cross section for example, an elliptical or rectangular cross section can be selected.
  • the element is shaped in order to increase the strength in such a way that the cross section is a curved or angled, d. H. has a crooked shape.
  • the support means can be attached to the guide of the conveyor belt. But it can also be connected directly to the machine frame.
  • the empty sleeves 24 are placed on one side of the spinning or twisting machine on the conveyor belt and are moved and positioned by this in such a way that they can be gripped by the pull-off bar 32 for replacement with full sleeves 18.
  • the support means 25, 36 or 38 can at least at the points with which the sleeves come into contact with a low-friction surface.
