Definitions

  • the invention relates to a take-off roller for flat knitting machines, with individual roller elements rotatably mounted on a take-off shaft and between the roller elements with axial play to these arranged, covered by the roller elements intermediate rings which are rotatably connected to the take-off shaft and each with a roller element torsionally connected.
  • a goods take-off roller is known for example from DE-PS 33 31 052.
  • the goods take-off device most frequently used in flat knitting machines is one with a goods take-off roller as described at the beginning.
  • the knitted fabric is pulled off the rolling elements.
  • These short roller elements are pushed onto the trigger shaft, which is provided with a keyway, and provided with a pin, in which a tension spring is suspended.
  • Each roller element is a disc or an intermediate ring assigned, which has a nose protruding into the keyway and is thus connected in a rotationally fixed manner to the trigger shaft.
  • the tension spring of each roller element is connected at the other end to the associated intermediate ring, so that the roller elements can rotate resiliently with respect to the trigger shaft.
  • the intermediate rings rotate synchronously with the draw shaft, while the roller elements which are intended to pull the knitted fabric down are influenced differently by the latter. Since different pulling forces prevail over the entire working width of the material take-off roller, the pulling rollers rotate asynchronously with respect to the pull-off shaft over a certain range due to the intermediate tension springs, and the different knitting tensions that occur over the entire knitting width are balanced.
  • a game is provided between the roller elements and the intermediate rings, so that each roller element can rotate unaffected by the adjacent roller element and by the tension spring to the associated intermediate ring on rotational tension differently over a certain range of rotation.
  • the knitted fabric now tends to contract in width, so that axial forces occur on the roller elements and the roller elements come into contact with one another via the intermediate rings.
  • a different amount of rotational friction is generated, so that adjacent roller elements cannot work in an undisturbed manner. Namely becomes a The roller element is rotated by the knitted fabric and the associated tension spring, so that due to the friction force that occurs, the adjacent roller element is either carried along, or the rotating roller element is prevented from rotating.
  • the invention has for its object to provide a goods take-off roller of the type described in the opening paragraph, in which adjacent roller elements can work independently of one another, ie do not influence one another.
  • the intermediate rings are preferably non-displaceably rigidly connected to the trigger shaft in the axial direction. You can be screwed or pinned to the trigger shaft.
  • Another advantageous embodiment of the invention consists in that axially extending spacers abutting the intermediate rings are provided between the intermediate rings.
  • the spacers can be inserted into a keyway of the trigger shaft into which the lugs of the intermediate rings engage, wedge parts abutting the lugs.
  • the spacers may be tubular pieces supported on the draw-off shaft.
  • the goods take-off rollers shown in FIGS. 1 and 2 each have a take-off shaft 1 provided with a keyway 2.
  • Rotatable roller elements 3 are pushed onto the take-off shaft 1 relative to the latter.
  • Intermediate disks or intermediate rings 4, which are covered by the roller elements 3, are pushed axially between the roller elements 3 onto the draw-off shaft 1, one intermediate ring 4 of which is assigned to each roller element 3.
  • Each intermediate ring 4 has a nose 5 on, which protrudes into the keyway 2 and ensures a rotationally fixed connection between the intermediate ring 4 and the trigger shaft 1.
  • Each roller element 3 is provided with a pin 6, in which a torsion spring or tension spring 7 is suspended. The tension spring 7 is connected at its other end to the intermediate ring 4 assigned to the respective roller element 3.
  • the individual short resilient roller elements 3 can rotate with respect to the take-off shaft 1 under the spring load and the load caused by various knitted fabric tensions over a certain range of rotation.
  • the take-off shaft 1 rotates when pulling off a knitted fabric, then the intermediate rings 4 rotate synchronously as a result of the engagement of their lugs 5 in the keyway 2. Since different pull-off forces occur on the individual roll elements 3 over the entire working width of the goods take-off roll, the roll elements 3 rotate with respect to the take-off shaft 1 due to their spring loading and under the influence of the different fabric tensions.
  • these means consist in that the intermediate rings 4 are screwed or pinned to the draw-off shaft 1 at 10 in such a way that successive intermediate rings 4 have minimum axial distances A.
  • the intermediate rings 4 are rigidly connected to the trigger shaft 1, so that they can absorb lateral axial pressures of the roller elements 3 and no longer transfer them to adjacent roller elements 3.
  • Fig. 2 shows a goods take-off roller in which to achieve the desired minimum distance A between the intermediate rings 4 spacers 11 in the form of wedge pieces are inserted in the keyway 2 in such a way that they each extend from nose 5 to nose 5 of successive intermediate rings 4.
  • the entire longitudinal composite is pushed together at the stop of the lugs 5 and spacers 11 and fixed, for example, by outer adjusting rings.
  • the fixation can also be done by a rigid connection of outer intermediate rings 4 to the trigger shaft 1.
  • the spacers 11 are longer than the bearing points of the roller elements 3. Thus, the roller elements 3 always have a permanent and unchanged axial play.
  • roller elements 3 lay against the intermediate rings 4, which are also axially fixed by the spacers 11 and are non-rotatably connected to the take-off shaft 1, and generate a rotational friction there without these being transferred to adjacent roller elements 3 can.
  • the spacers 11 can also be designed as tubular pieces mounted on the take-off shaft 1, on which in turn the roller elements 3 are mounted. This version is not shown in the drawing.
