Definitions

  • the present invention relates to a turntable for sliver storage devices with a band channel.
  • a turntable for depositing slivers in sliver cans with a channel is known, the sliver opening from an inlet part above and in the axis of rotation of the turntable via an arcuate curvature in plan to an underlying, tangent to the turntable and leads approximately to the circumference of the outlet part.
  • the channel has a straight and radial intermediate piece between its inlet part and its outlet part. Particularly in the case of modern, very fast-running machines with such turntables, it has been found that such channels lead to unfavorable and uneven sliver storage.
  • the channel is composed of at least two pipe elbows bent in a circular arc. Due to the telescopic composition of the elbows, the course of the channel can be adapted to the different can diameters.
  • the two pipe elbows are provided with straight ends at their connection point.
  • this device also has the disadvantage that the sliver has a pipe elbow edge must be performed and runs through a changed channel cross-section. In the case of fast machines in particular, such a design is not well suited for high accuracy when laying the sliver and for gentle handling of the sliver. Deposits can form on the edge, which peel off from time to time and lead to irregularities in the sliver.
  • the object is achieved by the features of claim 1. If the band channel is formed from a piece of pipe with two circular arcs that merge directly into one another, only slight acceleration forces act on the fiber band. Because no straight piece is arranged between the arcs, the sliver is guided gently in the sliver channel, so that practically no permanent deformation after storage in the sliver can is detected in the sliver. This even and gentle storage of the sliver is of great importance in the modern, very precise and fast draw frames and cards, so as not to destroy the previously produced sliver again during storage.
  • both arcs have essentially the same radii, this has a positive effect on the acceleration of the sliver off, since in this case the sliver is wound in large radii and thus small deflection forces act on the sliver.
  • both arcs have a common tangent at their transition, a constant and edge-free transition of the arcs is guaranteed.
  • the sliver channel should consist exclusively of circular arcs.
  • the circular arc-shaped run-out of the band channel has a positive effect on a low-force placement of the sliver.
  • An angle of 130 ° has proven itself for an inclination of the planes in which the arcs are arranged.
  • the transition of the band channel to the horizontal preferably takes place at a deposit angle of approximately 15 °.
  • the band channel and / or a cover of the turntable is made of stainless steel.
  • FIG. 1 shows a section through a turntable 1 according to the invention with a belt channel 2.
  • Sliver enters the belt channel 2 in an inlet 5, passes through the belt channel 2 and exits the belt channel 2 at an outlet 6.
  • the inlet 5 of the band channel 2 is arranged centrally in the turntable 1.
  • a casting compound 4 connects the band channel 2 to a plate holder 3. This ensures that the band channel 2 is always correctly positioned and does not change its position due to external influences.
  • the band channel 2 is also fixed at its outlet 6 with a casting compound 8.
  • the casting compound 8 ensures that a gap-free transition between the band channel 2 and the turntable 1 on the underside of the turntable 1 is ensured.
  • the underside of the turntable 1 is provided with a cover 7.
  • the cover 7 is advantageously made of stainless steel. This ensures that extremely little friction and little wear occurs between the sliver 10 deposited in a sliver can and the underside of the turntable 1. In addition, complex processing of the bottom of the turntable 1, in particular grinding and filling of the cast aluminum turntable 1, is avoided. Less care must also be taken when pouring the band channel 2 with the casting compound 8 into the turntable 8.
  • the device according to the invention advantageously has the effect that, with a large distance 9, no sliver is flung out over the edge of the sliver can during storage. Rather, the sliver is deposited in the spinning can 10 without a large radial speed component. This ensures a particularly even and orderly placement of the sliver. In addition, the orderly filing also ensures that the sliver is conveniently pulled out of the can 10. This is particularly important at high delivery speeds. The ejection of the sliver can be observed in particular in the first layers of the sliver deposited in the spinning can 10 in known generic devices.
  • An axis of rotation 11 of the turntable 1 is a tangent to the inlet bend of the band channel 2.
  • a center line 14 of the band channel 2 runs from the axis of rotation 11 at the inlet 5 of the band channel 2 to the outlet 6 and essentially represents the deformation of the fiber band when passing through the band channel 2.
  • the center line 14 of the band channel 2 is shown in an XYZ coordinate system.
  • the coordinate system is laid out in such a way that the inlet has 5 X and Y values 0 and the outlet 6 has Y and Z values 0.
  • the center line 14 is formed from two arcs.
  • the first arc has a center M1 and designates the outlet arch.
  • the inlet arch has its center in a center M2.
  • Both arches have the same radius R.
  • the same radius R ensures that the fiber sliver is subjected to the lowest possible load when passing through the sliver channel 2.
  • the radius R should be as large as possible so that there is a uniform force on the sliver during the entire passage through the sliver channel 2.
  • the arcs which are formed around the center M1 and M2 merge directly into one another.
  • the arcs therefore have a common tangent T at a turning point W.
  • the end of the outlet bend 15 is determined by a fixed depositing radius Ra, a depositing angle ⁇ 1 of the exit tangent to the surface of the turntable, which corresponds to the Y-axis of the coordinate system, and by a height H of the belt channel 2.
  • the inlet bend 16 is shorter than the outlet bend 15.
  • the inclination of the plane E at an angle ⁇ to the Y axis ensures a short path through the band channel 2 which is low in acceleration for the sliver.
  • Figure 3 shows a representation of the inclination of the plane E of the inlet bend 16 to the plane A of the outlet curve 15.
  • the angle of inclination ⁇ is approximately 125 ° in the exemplary embodiment shown.
  • the planes E and A intersect in the tangent T.
  • the center points M1 and M2 of the two arcs of the band channel 2 are also in the plane A and E.
  • a view B in FIG. 3 is shown in FIG.
  • FIG. 4 shows a representation of the center line 14 of the band channel 2, in which the inlet bend 16 is shown undistorted.
  • the inlet bend 16 has the radius R around the center M2.
  • the inlet bend 16 extends over an angle ⁇ 1, which here is approximately 70 °.
  • FIG. 4 shows, in addition to the outlet bend 15 and the inlet bend 16, a straight line 12 in front of the inlet bend 16.
  • the straight line 12 is arranged in the semi-finished product for manufacturing reasons. This ensures that the arches 15 and 16 bend with tolerance, since the workpiece can be clamped in a bending device.
  • the straight line 12 is separated from the arches 15 and 16 during the finishing of the band channel 2. By deburring the inlet 5, low-friction insertion of the sliver into the sliver channel 2 is ensured.
  • FIG. 5 shows a view in the direction of arrow C in FIG. 3.
  • the center line 14 of the band channel 2 has a radius R and the center point M1 in the outlet arch 15.
  • Inlet bend 16 merges directly into outlet bend 15 at inflection point W.
  • the outlet bend 15 has an angle ⁇ 2 which is approximately 127 °.
  • a straight line 13 is arranged after the outlet curve 15 in the semi-finished product. As with the straight line 12 on the inlet bend 16, the straight line 13 on the outlet bend 15 ensures that the preferably stainless steel tube, which is used for forming the band channel 2, is securely clamped in the bending tool.
  • the straight line 13 is cut off when the band channel 2 is completed.
  • the end of the outlet bend 15 is preferably deburred.
  • FIG. 6 shows a band channel 2 in a view radially to the turntable 1.
  • the straight lines 12 and 13 separated in the finished product are shown in dashed lines.
  • the inlet bend 16 forms a common tangent T with the outlet bend 15 at the turning point W.
  • Both the inlet bend 16 and the outlet bend 15 have the same bending radius R.
  • This has proven to be particularly advantageous since the acceleration forces on the fiber sliver are particularly uniform.
  • the outlet 6 is designed such that it ends flush with the bottom of the turntable 1.
  • the outlet bend 15 enters the bottom of the turntable 2 at an angle ⁇ 1.
  • a placement angle of 15 ° has proven to be advantageous for a distortion-free placement of the sliver.
  • a radius R of approximately 80 mm has been found to be particularly gentle on the sliver.
  • FIG. 7 shows a representation of the band channel 2 in the direction of rotation of the turntable 1.
  • the direct transition of the inlet bend 16 into the outlet bend 15 into the turning point W is also shown here.
  • the height H of the sliver channel 2 is predetermined by the structural requirements of the sliver storage device.
  • the choice of the circular arcs used for the inlet arch 16 and the outlet arch 15, as well as the inclination of the planes B and A with respect to one another, is based on this height H and on a further predetermined storage radius Ra.
  • FIG. 8 shows a view of the band channel 2 in the axial direction of the turntable. It can clearly be seen from the illustration in FIG. 8 that a round tube was used as the starting material in the exemplary embodiment shown. According to the invention, however, other cross sections can also be used for the band channel.
  • the storage radius Ra is approximately 140 mm. This has proven to be advantageous when storing sliver in spinning cans 10 with a diameter of 450 mm. This ensures warp-free storage of the sliver with optimal filling of the sliver can 10 with sliver.
  • the present invention is not restricted to the exemplary embodiment shown.
