Definitions

  • the invention relates to a drafting device for spinning machines, in particular for drawing, for processing a sliver with a stacking area of cotton and / or plastic fibers in a preliminary and a main drawing zone, comprising drawing zones delimiting sub-cylinders arranged on a machine frame and above that assigned to each sub-cylinder Printing cylinder, wherein the first printing cylinder delimiting the main stretching zone is arranged so as to be displaceable and fixable on an arc around the axis of rotation of the corresponding lower cylinder.
  • DE-PS 1250315 shows and describes a drafting system with, viewed in the running direction of the sliver, an input cylinder pair, a middle cylinder pair and an output cylinder pair, each consisting of a lower cylinder and an associated pressure cylinder.
  • the input and middle pairs of cylinders together form a leading, while the middle and output pairs of cylinders form a main stretching zone.
  • the pair of input cylinders viewed in the running direction of the sliver, can be moved linearly back and forth in order to change the length of the pre-stretching zone. Both cylinders can be moved independently of each other.
  • the middle and the output lower cylinder are rigid, while the middle and the output pressure cylinder are arranged linearly displaceable in the same way as the input pressure cylinder.
  • All three printing cylinders are vertically movable with respect to a base plate receiving the pedestals of the lower cylinders, so that when the printing cylinders are linearly displaced, in combination with the vertical mobility, they can perform a movement around the fixed or fixed lower cylinders. This makes it possible to change the length of the main stretching zone and to adapt it to a certain extent to the stack length.
  • the output lower cylinder has a larger diameter than all other cylinders.
  • the bearing blocks of the printing cylinders are arranged so as to be linearly displaceable on the bearing blocks of the lower cylinders.
  • the pressure on the pressure cylinder is exerted by spring-loaded pressure pistons, which are attached to a swivel and lockable bracket.
  • CH-PS 426 570 shows and describes a drafting system with a pre-stretching and a main stretching zone, in which a pressure cylinder is arranged pivotably around the axis of a lower cylinder, as a result of which the loop of the sliver is lengthened or shortened.
  • a pressure cylinder is arranged pivotably around the axis of a lower cylinder, as a result of which the loop of the sliver is lengthened or shortened.
  • the accuracy of the assembly is also decisive for the service life of a bearing, e.g. with respect to the parallelism of the pressure and sub-cylinders to one another and with regard to the exact alignment of the cylinder shafts to the elements driving the shafts.
  • Another disadvantage is the large diameter of the output cylinder, since this increases the distance between the clamping lines of the main stretching zone.
  • the drafting system has the disadvantage that in order to e.g. To be able to run in a can, an additional deflection of the belt after the drafting system is required, which is necessary for the belt at belt speeds of 13.3 m / sec. and more results in an additional, undesirable centrifugal load and thereby creates a procedural disadvantage.
  • a drafting device with three drawing zones is known from French Patent No. 1196 694, in which the lower cylinders, as well as the printing cylinders, are arranged opposite one another in concentric circles, the printing cylinders being located on the outer circle.
  • Such drafting systems are used in pre-spinning or ring spinning machines and work at belt speeds at the exit of the drafting system of max. 40 m / min. in leader and max. 20 m / min. in ring spinning machines.
  • the arrangement on concentric circles was chosen in order to obtain more space for large diameter printing cylinders without increasing the distance between adjacent clamping lines. These Increasing the diameter reduces the risk of winding on the pressure cylinders of such drafting systems.
  • an intermediate guide element is provided, on which the fiber sliver or the fiber sliver is deflected such that the fiber sliver or the fiber sliver passes the mentioned clamping lines in the tangential direction.
  • the sliver is deflected on a roller only on the last lower roller, seen in the running direction of the sliver, and only after the clamping line.
  • An advantageous embodiment of the drafting arrangement consists in the arrangement of the pressure cylinders on the pivotable arm. This means that even wide fiber slivers can be easily and safely inserted into the drafting system.
  • Another advantageous embodiment consists in that the displaceable printing cylinders can be adjusted by means of rastering to adapt to the stack length, and the extent of the displacement can be measured by means of a scale, so that they can be displaced quickly and precisely, which, despite the displaceability of the printing cylinders, ensures precise parallel guidance of the Pressure cylinder to the lower cylinders guaranteed.
  • the displacement of the second pressure cylinder delimiting the main stretching zone on an arc around the axis of rotation of the corresponding lower cylinder enables the sliver to be tangentially fed into this cylinder pair, regardless of whether a push rod with positive or negative deflection of the sliver is used.
  • the small diameter of the second lower cylinder delimiting the main stretching zone has the advantage that, despite the also advantageous large diameter of the previous lower cylinder, an optimally short clamping distance can be achieved.
  • a drafting system 1 comprises a machine frame 2, on which the arm parts 4 forming a double arm are pivotably mounted by means of a hinge pin 3.
  • the arm parts 4 each comprise an arch part 5 and an arch part 6 and an end part 7.
  • a notch 8 is provided on the end part 7 for receiving a fixing bolt 9 each.
  • the fixing bolt 9 is part of a pneumatic cylinder 10.

  • the bearing block pair 25 is in the guide slot 60 arranged movable and fixable again to ensure the tangential entry of the sliver despite the changeable entry position of the sliver, caused by the displacement of the pressure cylinder 30.
  • raster teeth 32 and 32 are shown on the arc parts 5 and 6 (FIGS. 3 and 4). and a raster scale 33 corresponding to the number of teeth and, on the other hand, a raster device 34 which engages in the teeth 32 is provided on the bearing block pairs 21 and 23.
