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 rotatably 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 assigned a disc or an intermediate ring, which has a nose protruding into the keyway and is thus connected to the pull-off shaft in a rotationally fixed manner.
- 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 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.
- 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.
- a further 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 which protrudes into the keyway 2 and for a rotationally fixed Ver bond between intermediate ring 4 and trigger shaft 1 ensures.
- 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 intermediate rings 4 rotate synchronously as a result of the engagement of their lugs 5 in the keyway 2. Since different take-off forces occur on the individual roll elements 3 over the entire working width of the goods take-off roller, the roller elements 3 rotate in relation 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 such 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 transmit 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 into 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 pull-off shaft 1, and generate a rotational friction there without being transmitted 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.
