Definitions

  • the invention relates to a double-twisting or Kablierspindel according to the preamble of claim 1, see for example DE-29,31,391C2 ,
  • Modern double-twisting or Kablierspindeln usually have a stationary protective pot for receiving a supply bobbin, a hollow coil axis for guiding a thread through the twisting spindle and arranged below the feed bobbin, rotatably mounted, drivable spindle.
  • the thread is guided over a thread brake and then leaves the region of the coil axis via a radial opening which is arranged in a component of the rotatably mounted, drivable spindle.
  • the thread After exiting the radial opening, the thread is temporarily stored on a storage disc of the spindle, before being guided to a fixed above the protective cup, stationary balloon yarn guide.
  • the thread forms due to the rotation of the spindle between a arranged in the storage disc, so-called discard plate and arranged above the protective cup balloon yarn guide a rotating around the protective cup yarn balloon.
  • the balloon thread guide After passing the balloon thread guide the twisted or cabled thread is wound by a winding device to a package.
  • the double-twisting or cabling spindles often have, as in the DE 10 2006 029 055 A1 described, a driven by a tangential spindle, which in turn has a circumferential storage disc and a arranged above the storage disc, fixed to the storage disc thread-discard.
  • the diameter of this known thread-throwing disc is sized, that it is above the diameter of the stationary protective pot.
  • the yarn balloon circulating between the yarn discharge plate and the balloon yarn guide arranged above the protective pot generally has a relatively large diameter.
  • the supply bobbin is not protected in a stationary protective pot arranged, but is open on a designed as a bobbin component of the double-twisting spindle.
  • cylindrical yarn guide is provided which surrounds the supply spool in height of the Balloonbe interroberkante.
  • the double-twisting spindle according to DE 33 47 318 A1 has a bulky, cylindrical balloon limiter, in which a stationary protective pot, which has conically shaped end regions, is mounted.
  • the maximum diameter of the resulting thread balloon is determined by the inner diameter of a stationary, outer balloon limiter, so that the threads to be processed are not insignificantly loaded during the twisting process.
  • the protective pot is also equipped in the area of the reservoir with an annular disc, which consists of an absorbent material.
  • the present invention seeks to modify a double-twisting or Kablierspindel so that the resulting during the twisting or Kablierreaes thread balloons are as slim as possible, with the disadvantages described above, in particular the sliding along the thread on a outer, stationary balloon limiters, should be avoided.
  • the rotatably mounted spindle which guides the thread during the twisting or cabling, has a storage disc on the lateral surface of the thread slides.
  • the spindle has, in addition to the storage disk, a thread discharge disc fixed to the storage disc.
  • Such a thread-dumping disc is usually set on top of the storage disc and is an advantageous thread guide means.
  • the thread-throwing disc has a curved edge portion which rotates during the twisting or Kablierluies with play in an annular, downwardly open recess of the pot bottom of the protective pot.
  • the pot bottom of the stationary protective pot on its outer side, on which the thread slides during the twisting or Kablierreaes along has a thread-friendly deflection radius.
  • Such a thread-friendly deflection radius whose dimension is between 8 mm and 20 mm, ensures that the thread sliding along the bottom of the pot during the twisting or cabling process is not overstressed or even damaged.
  • an adapter is arranged, which is rotatably connected to the pot bottom of the protective pot.
  • the contact surface of the thread can be minimized at the bottom of the pot and at the same time the thread balloon formed during the twisting process can be made slimmer.
  • the adapter is covered by a arranged on the bottom of the pot, reaching to the discard, conically shaped shell piece (Anspr.7).
  • the protective pot has a conical region below the line of contact of the thread with the protective pot.
  • Such a design of the protective pot allows a simple way of optimally receiving conical or biconical feed bobbins in the protective pot.
  • the protective pot can always be maximally equipped even when processing such trained supply bobbin.
  • the protective pot is equipped in this area with a guide ring or a guide bead (Anspr.9).
  • the guide ring or the guide bead are preferably made of a hard and thread-friendly material, for example made of chrome-plated or polished steel, and ensure that the thread can not be damaged during the twisting or cabling process by the stationary protective pot.
  • the guide ring or the guide bead is either attached to the pot bottom of the protective pot or fixed in the lower part of the pot casing surface of the protective pot. Both sites have proven to be beneficial in practice.
  • a distance a is given, which can be between 1 and 120 mm ,
  • the Fig.1 schematically shows a workstation 30 of a (not shown) double-twisting machine or cabling.
  • Such workstations 30 have inter alia a double-twisting or cabling spindle 1, with a supply bobbin 4 mounted in a stationary protective pot 3, and a winding device 31 for winding the twisted yarn 5 into a package 32.
  • the stationary protective pot 3 which has a relatively large diameter D, has a pot bottom 2. Below the
  • Pot bottom 2 is a rotatably mounted spindle 6 of the double-twisting or cabling 1 arranged.
  • the spindle 6 is provided for rotating and guiding the thread 5 during the twisting or Kablierluies with a storage disc 12 and a thread-Abschteller 13, wherein the diameter d of the thread-Abschtellers 13, in this case the largest diameter of rotatably mounted spindle 6 forms, as can be seen, significantly below the diameter D of the stationary protective pot 3.
  • the thread 5 is then, as known and therefore not explained in more detail, acted upon within the coil axis 25 by a (not shown) yarn brake and guided over the rotationally driven spindle 6 to the outside.
  • the thread 5 passes through a radial opening 40 in the storage disk 12 of the rotating spindle 6 on the circular circumferential or lateral surface of the storage disk 12, where it is temporarily stored, depending on the particular thread tension present.
  • the thread 5 leaves the rotating spindle 6 in the illustrated embodiment on the thread-Abschteller 13, wherein the thread 5 during the twisting or Kablierreaes between a line of contact 23 in the region of the pot bottom 2 of the protective pot 3 and arranged above the protective pot 3, stationary balloon yarn guide 33 forms a relatively slim thread balloon 50.
  • the twisted yarn 5 After passing through the stationary balloon yarn guide 33, the twisted yarn 5 is wound by means of the winding device 31 into a package 32.
  • the Fig.2 shows in detail a first embodiment of the inventive double-wire twisting or Kablierspindel 1, wherein both the rotatably mounted spindle 6 and the upper bearing means 11 for the stationary protective pot 2 and arranged below the stationary protective cup 2 bearing means 7 for the spindle 6 in section are shown.
  • the bearing devices 7 and 11 preferably each have two axially spaced-apart rolling bearings.
  • the bearing device 7 is arranged in a bearing housing 9, which is fixed in a spindle bank 8 of the double-wire twisting or cabling machine, in which the spindle 6 of the double-wire twisting or cabling spindle 1 is rotatably mounted with its spindle shaft 43 ,
  • a whorl 44 is pressed, which is acted upon during the twisting process by a drivable tangential belt 10.
  • a bore 26 which serves to facilitate the threading of the thread 5 in the double-twisting or Kablierspindel 1 and which is connected via a pressure line 27 and a defined controllable valve means 28 with a compressed air source 29 ,
  • a storage disk 12 is non-rotatably connected to an intermediate part 34, which is preferably part of the spindle shaft 43.
  • a likewise connected rotationally fixed to the spindle shaft 43 spindle start part 35 forms the basis for the storage device 11 of the stationary protective pot.
  • the bearing device 11 has, for example, two axially spaced-apart rolling bearings.
  • the rolling bearings are fixed with their inner rings on the spindle start part 35, while the cup bottom 2 of the protective pot 3 is mounted on the outer rings of these bearings.
  • the intermediate part 34 and the spindle starting part 35 are also provided with internal bores, with both the bore 36 of the spindle starting part 35 and the bore 37 of the intermediate part 34 merging into the radial opening 40 of the storage disc 12.
  • a thread-Abschteller 13 whose largest diameter d clear, that is, at least 10% below the diameter D of the stationary protective pot 3.
  • the yarn discharge plate 13 grips with play into a circular recess 15, which is arranged on the underside of the pot bottom 2 and opens downwards.
