Definitions

  • the invention relates to a drafting system for spinning machines for stretching a staple fiber wadding, a staple fiber tape or a staple fiber sliver as described in the preamble of the first claim.
  • drafting systems In drafting arrangements, staple fiber tiles, staple fiber tapes or staple fiber slips are stretched in stretching zones, which are each limited by two pairs of rollers.
  • roller pairs each consist of a lower roller and a pressure roller that can be pressed onto it.
  • drafting systems comprise two or more drawing zones, so that at least three pairs of rollers are arranged one behind the other with the distances corresponding to the drawing zone length.
  • the pressure rollers are arranged in a drafting frame and can be pivoted away from the lower rollers. The pressure rollers are pressed onto the lower rollers by means of force which act on the axle bearings provided on both sides of the pressure rollers.
  • the bearings that accommodate the lower rollers are body slidably arranged and fixable.
  • the last pair of rollers as seen in the direction of conveyance of the fiber structure, is, however, advantageously arranged in a fixed manner in order not to get any change in the position of these rollers in relation to the subsequent elements which receive the fiber sliver or the fiber wadding.
  • the main draft zone If the last draft zone, referred to as the main draft zone, is to be shortened or lengthened, the preceding pairs of rollers forming the pre-draft zones must be shifted accordingly to the same extent. If, for example, two pre-drafting zones and one main drafting zone are provided, a total of three pairs of rollers have to be displaced when adapting the main drafting zone, which is very time-consuming.
  • said last pair of rollers is also arranged to be displaceable and lockable, only this last pair of rollers can also be displaced.
  • German Offenlegungsschrift No. 2852692 that the amount of displacement of the lower rollers can be read off on a scale.
  • the printing roller is removed and one that fits into the printing roller bearing body on the one hand and the lower part on the other roller-receiving bar inserted into the bearing body of the pressure roller. In this way, the lower and the pressure roller can be moved simultaneously and to the same extent.
  • This process is carried out on each pair of rollers.
  • This device consists on the one hand in replacing the pressure roller with the mentioned bar and in reinstalling the pressure roller after moving, and on the other hand in that all the roller pairs delimiting the pre-draft zones must be adjusted one after the other.
  • a drafting system comprises an input roller pair 1, a first intermediate roller pair 2, a second intermediate roller pair 3 and an output roller pair 4.
  • the input roller pair 1 consists of the lower roller 5 and the pressure roller 6, the first intermediate roller pair 2 of the lower roller 7 and the pressure roller 8, the second Intermediate roller pair 3 from the lower roller 9 and the pressure roller 10 and the output roller pair 4 from the lower roller 11 and the pressure roller 12.
  • the lower roller 5, respectively. 7, respectively. 9, respectively. 11 is in two bearing body 14, respectively. 15, resp. 16, respectively. 17 rotatably mounted. In FIG. 1, only the right-hand bearing bodies, as seen in the running direction of the fiber structure, are visible.
  • FIG. 3 shows that these bearing bodies are each slidably arranged on a slide rail 18, secured against displacement in the axial direction of the rollers are.
  • each bearing body 16 of the third lower roller 9 or each bearing body 17 of the last lower roller 11 (only this variant shown in the drawings) is fixed with the corresponding rail by means of screws 19 connected.
  • the bearing bodies 14, 15, 16 and 17 of the lower rollers 5, 7, 9 and 11 are each connected to a connecting rail 21 by means of a screw 20.
  • the pressure roller 6, respectively. 8, respectively. 10, respectively. 12 is on both sides by a bearing saddle 22, respectively. 23, resp. 24, resp. 25 added.
  • FIG. 1 only the right-hand bearing saddle, as seen in the direction of conveyance of the yarn, is shown, while in FIG. 3 only the bearing saddles 25 receiving the pressure roller 12 are shown.
  • the bearing saddles in turn lie on a drafting frame leg 26 or 27 and are each frictionally locked by means of an adjusting screw 28 against displacement on the legs 26 or. 27 fixed.
  • Each bearing saddle serves to receive a bearing body 30 and has a guide slot 29 into which a guide part 301 belonging to each bearing body 30 is inserted.
  • the pressure rollers are supported in the force directions parallel to the legs 26 and 27, respectively.
  • a displacement of the bearing body 30 in the axial direction of the rollers is carried out by guiding the guide parts 301 on the inner walls of the Leg 26 and 27 avoided (only shown in Figure 3).
  • the cam 31 of a leaf spring 32 projects into the bearing bore of the bearing body 30.
  • the leaf springs 32 are each fastened by means of a screw 33 to the bearing saddle 22, respectively. 23, resp. 24, respectively. 25 attached.
  • a resilient element 34 is provided between the bearing bodies 30 and the legs 26 and 27 e 7. This spring element creates the contact pressure between the pressure and the lower rollers.
  • the saddles 22, 23 and 24 are connected by means of a screw 35 and the saddle 25 by means of a screw 36 to a connecting plate 37.
  • the screw 36 also extends into the leg 26 or 27, whereby the bearing saddles 25 become stationary relative to the leg 26 or 27, this variant being used only if the pressure roller 12 of the pair of output rollers is to be arranged in a stationary manner.
  • the second pair of intermediate rollers 3 can be stationary and the pair of output rollers 4 movable.
  • the screws 36 would fix the saddles 24 on the legs 26 and 27.
  • the connecting plate 37 has a sufficiently large size Slots 38, 39, 40, and 41.
  • the length and position of the slots relative to one another depend on the desired displacement of the pressure rollers and must be determined on a case-by-case basis.
  • the shafts 42 and 43 and 44 or 45 carrying the lower cylinders are driven by universal joints, while the shaft 44 or 45 is driven directly by the corresponding gear.
  • the gear arrangement with universal joints enables the shafts to be displaced along the bodies 18 from their position shown in the figures.
  • the displacement of the pressure and / or bottom rollers is always necessary if other lengths of staple fiber are present in the material to be stretched.
  • the cylinder pairs 1, 2 and 3 can be shifted by the same amount.
  • the screw 36 (FIGS. 1 and 3), the screws 28 and the screw 20 present in the bearing bodies 17 must be loosened.
  • the drafting frame legs 26 and 27 are received by means of one in two supports 46 and 47 Axle 48 is pivotally arranged, the supports 46 and 47 being fixedly connected to the rails 18.
  • the drafting frame is formed in that the legs 26 and 27 are firmly connected at their end opposite the axis 48 by a beam 49.
  • the drafting frame is held in the operating position shown in FIGS. 1 and 3 by means of a tensioning device 50 assigned to each leg 26 and 27.
  • the clamping device 50 is on the one hand by means of a pivot axis 51 on one, each leg 26 or. 27 fixedly assigned web 52 pivotally arranged and on the other hand hooked onto a hook 53 which is permanently assigned to each rail 18.
  • a variant consists in that, as indicated in FIGS. 1 and 3 with dash-dotted lines, instead of the supports 46 and 47, supports 54 and 55 are used, which on the one hand accommodate the axis 48 and on the other hand are fastened to the bearing body 14.
  • a consequence of this variant is that the bearing saddles 24 by means of screws 36 with the legs 26, respectively. 27 fixed and the bearing saddles 25, clamped by means of the screws 35, on the legs 26, respectively. 23 are slidably arranged.
  • the bearing saddles 25 must still be set to the distance from the bearing saddles 24 corresponding to the newly set main distortion field and fixed by means of the screws 35.
