Definitions
- the present invention relates to an inner ring on a spinning ring for ring spinning and ring intermediate machines, which is arranged coaxially while maintaining a gap-forming distance in the interior of the spinning ring, the upper runner guide surface of which is designed to receive an inner, downwardly ending rotor arm.
- the object of the present invention is to overcome the disadvantages of the described rings and runners and to propose a tool for a spinning ring which, even if crimping occurs, will certainly prevent unthreading without a standard runner and a normal ring which is suitable for such a runner to have to do without.
- an inner ring according to the preamble of claim 1, the upper end of which supports the untensioned thread in a higher position than the lower limit of the guide surface of the runner leg on the unlubricated spinning ring.
- the upper outer edge of the inner ring should be at such a distance from the guide surface of the rotor that there is no contact with the inner ring.
- the inner ring can also be provided with at least one slot opening extending in the circumferential direction.
- the slot opening can have a lower surface which merges into a surface delimiting the gap below.
- the inner ring can also be exchangeably attached to the spinning ring by a sliding or press fit, which results in the advantage of freedom of choice with regard to the materials. It can also be glued to the spinning ring.
- an inner ring is particularly advantageous, which is part of a fastening body for the spinning ring arranged on a ring bench of the machine.
- Such an injection molding process can be produced cheaply and without extensive rework.
- Fig. 2 shows a detail of Fig. 1, with the runner in the rest position
- Figure 3 shows a section through an inner ring with an annular flange for C-rotor.
- Fig. 4 shows a section through a variant of an inner ring.
- a ring bench 1 (Fig. 1) has a ring holder 2, in which an unlubricated spinning ring 3 is inserted and held in place by clamping tabs 4 in a known manner (eg CH-PS 458.152).
- the ring 3 has an upper inner surface 5, on which an attached rotor 6 rotates.
- the thread 8 running onto the bobbin 7 reaches the rotor 6 from the front at the front and leaves it behind in the direction tangential to the bobbin surface, and due to the centrifugal forces acting, the rotor 6 lies on the ring 3 with its inner leg 9 ending obliquely downwards.
- the surface of the ring 3 which is covered by the leg 9 is defined herein as the rotor guide surface 10.
- a concentrically arranged, tubular inner ring 12 Carried by the bottom wall 11 of the ring holder 2 is a concentrically arranged, tubular inner ring 12, the upper end 13 of which is higher by an amount h than the runner guide surface 10, which is covered by the running leg 9 and has a lower boundary B, and the outer edge 14 of which is only such a distance a (FIG. 2) assumes that the rotating rotor 6 has a still sufficient gap in the various operating stages.
- the size of this distance a (approx. 1 - 2.5 mm with a clear diameter Dr of 45 - 55 mm) is determined by the rotor 6 which is still pulled inwards from the thread due to a lack of centrifugal force, whose inner leg 9 must not touch the inner ring 12 even in this extreme position.
- the tubular inner ring 12 continues down to below the ring bench 1.
- Tuft of fibers suppressed or inhibited, which give the coil a rough, unsightly appearance.
- the diameter Dr is approximately the same size as the diameter Di.
- one or more slits 23 running in the circumferential direction can be provided, which serve to allow debris to be thrown outwards.
- the position is advantageously to be set up such that the lower surface 24 of the slot 23 and the upper surface 25 of the foot 21 are at the same height.
- the ring holder 1 (FIG. 1) together with the inner ring 12 is advantageously designed as a uniform injection molded part.
- 3 provides as a variant a spinning ring 19 installed in a bore 18 of the ring rail 1.
- An inner ring 22 equipped with a reinforcing foot ring 21 is inserted in the lower inner surface 20 thereof, which can be pressed or glued.
- the spinning ring 19 has a conventional flange 26 for a C rotor 27.
- the diameter Di is necessarily smaller than Dr since the inner ring 22 is drawn up between the rotor 27 and the coil 7.
- Dr the inner ring 22 is drawn up between the rotor 27 and the coil 7.
- the conditions described above apply as for distance a.
- the standstill position of the rotor 27 is shown in dash-dot lines.
- the spinning ring 28 has a cylindrical surface 29 on the inside which, together with the outer surface 30 of the inner ring 31 to be accommodated, forms a sliding seat so that it can be easily removed for cleaning.
- a sliding seat a press fit can also be selected.
- the material of the removable inner ring 31 can be made of plastic or another cheaper material than that of the wear-resistant i.e. of the higher quality material of the spinning ring 28.
- one or more slots 32 are provided in the inner ring 31 which also extend to remove rotor debris, the lower surface 33 of the slot 32 merging into the conical surface 34 of the spinning ring 28.
- the coil 7 stops after a short time.
- the residual tension which is still small at most, is negligible
- it is able to lower due to gravity, reinforced by the formation of cranks, along the runner leg 9, which is no longer in contact with the surface 10, and reaches the position indicated in FIG. 2 , in which the upper end 13 of the inner ring prevents further lowering of the thread and thus does not get beyond the lower end 35 (FIG. 2) of the running leg 9. Slipping out the thread 8 from the rotor 6 is practically impossible.
- the threading is thus effectively suppressed even in the restart phase.
- the downtime of the spindle is reduced and the efficiency of the machine is considerably increased.
