Definitions

  • the invention relates to a disintegration unit of an open-end spinning device, consisting of a housing into which a disintegration roller is inserted, which has an inlet opening for the sliver to be disintegrated, a feed trough and an outlet opening for the fiber feed channel leading to the spinning device, wherein between the area of the feed trough and the fiber feed channel leading to the spinning device has a fiber parallelization segment with parallelization elements which are arranged next to one another in parallel rows.
  • the result of open-end spinning devices can be improved if the fibers of the dissolved sliver have been parallelized particularly well before they are fed into the spinning device via the fiber feed channel.
  • the opening roller with a set consisting of needles or sawtooth-shaped opening elements, but also the housing wall opposite the opening roller, in particular in the area between the feed trough and that to the spinning device leading fiber feed channel.
  • a dissolving device for open-end spinning machines in which so-called parallelization segments are inserted into the wall of the housing of the dissolving device in the fiber transport direction before the opening for separating the dirt and before the opening of the fiber feed channel.
  • These parallelization segments form a uniform segment block, which is in a corresponding recess in the housing can be used interchangeably.
  • transition points are formed at the points where the segments are used, at which dissolved fibers can get caught and accumulate. Such fiber accumulations can interfere with the spinning process if they detach from the gaps and are sucked into the spinning device.
  • the fiber parallelization segment is a component of the wall of the housing and the parallelization elements, needles or adjacent, sawtooth-shaped strips, rise from a recess in the housing wall.
  • the parallelization segment is not inserted into the housing, but is worked out of it, so that no transitions and gaps can form in which the fibers can become lodged.
  • the tips of the parallelization elements should be arranged concentrically with the opening roller and aligned with the inner contour of the housing. This ensures that the parallelization elements are all aligned in the same direction and all take the same distance from the opening roller.
  • the parallelization elements can be worked out of the wall of the housing. This can be done, for example, by milling, grinding or eroding. This is absolute ensures that no columns are formed by inserting a parallelization segment.
  • the recess in the wall of the housing is given a special shape. It is advantageous if the recess in the wall is formed by a circular concave contour in the circumferential direction of the inner contour of the housing. The center of this contour lies on a perpendicular to the secant, which goes through the intersection points which are formed by the intersection of the concave contour with the inner contour of the housing. The central perpendicular goes through the central axis of the cylindrical inner contour of the housing.
  • the recess in the wall of the housing an, for example, parabolic, hyperbolic or ellipsoidal concave shape.
  • the shaping can take place in such a way that an optimal parallelization effect results in each case for a specific type of fiber.
  • the size of the parallelization elements increases continuously from the beginning of the fiber parallelization segment in order to achieve a maximum shape in the middle and then continuously decrease to zero.
  • those in parallel and in Rows of parallelization elements standing next to one another are therefore only those of the same size in a row perpendicular to the circumferential direction of the housing wall at the intersection of the perpendicular to the secant with the concave contour.
  • the recess in the wall of the housing can be formed by a circular concave contour perpendicular to the circumferential direction of the inner contour of the housing.
  • the center of this contour lies on a perpendicular to the secant which passes through the intersection points which are formed by the intersection of the concave contour with the inner contour of the housing.
  • the center perpendicular goes through the center line of the cylindrical inner contour of the housing.
  • the embodiment described above and the new concave contour are superimposed.
  • the two centers of the two contours should coincide.
  • the size of the parallelization elements increases continuously from the edge towards the center of the recess.
  • the largest number of parallelization elements is in the central region of the opening roller, and the parallelization elements there also have the greatest height relative to the contour of the recess.
  • a opening roller 2 which is equipped with a set 3, here sawtooth-shaped.
  • the opening roller 2 is mounted with an axis 4 in the wall of the housing 1.
  • the sliver 5 is fed to the opening roller 2 via a compressor 6 from a feed roller 7 through the feed opening 8 in the housing 1.
  • the feed tray 9 is pivotable stored and is pressed with a spring, not shown here, against the feed roller 7 in order to be able to adapt to changing thicknesses of the sliver.
  • the opening roller 2 combs 5 individual fibers 11 with its clothing 3 from the fiber beard 10 of the fiber sliver projecting beyond the feed trough 9.
  • the combed fibers 11 are entrained by the air flow prevailing in the housing 1.
  • This air flow can be, for example, the negative pressure which is present on a spinning rotor of the spinning device. While the light fibers 11 follow the air flow, the dirt 12 is discharged from the dirt discharge opening 13 in the housing 1 due to the centrifugal force acting on it. The dirt 12 falls into a device for collection or removal, not shown here and not described in detail.
  • the wall of the housing 1 relative to the opening roller 2 continues in a fiber parallelization segment 15 which is equipped with parallelization elements 16 and extends to the outlet opening 17 of the fibers 11 in the fiber feed channel 18 .
  • the fiber feed channel 18 leads to the spinning device, not shown here.
  • the fiber parallelization segment 15 is part of the wall of the housing 1 of the resolving unit. It consists of a recess A within the wall of the housing 1.
  • the recess A in the wall of the housing 1 is formed by a circular concave contour K in the circumferential direction of the inner contour I of the housing 1.
  • This recess A is filled by parallelizing elements 16.
  • These parallelizing elements like the clothing of the opening roller, can be sawtooth-shaped or needle-shaped.
  • the tips 16 'of the parallelization elements 16 are arranged concentrically to the opening roller 2 and aligned with the inner contour I of the housing 1.
  • the gap between the clothing 3 on the opening roller 2 and the tips 16 'of the paralleling elements 16 is the same size as between the clothing 3 and the inner contour I of the wall of the housing 1.
  • the parallelization elements 16 can be machined out of the wall of the housing 1, for example by grinding, eroding or milling. But they can also, and this is especially the case with needles, be inserted into the housing wall.
  • the parallelization elements are arranged side by side in parallel rows. They are sawtooth-shaped and their sawtooth shape is arranged in relation to the sawtooth patterns of the clothing 3 on the opening roller 2 and rotated 180 degrees.
  • the recess A has a circular contour K.
  • the center MK of the circular contour K lies on a perpendicular perpendicular SM, which is perpendicular to a secant S.
  • the secant S runs through the two intersections of the circular contour K with the circular inner contour I of the wall of the housing 1.
  • the perpendicular perpendicular SM runs through the center of the circular inner contour I of the housing 1.
  • the radius RI of the inner contour I is larger than the radius RK the circular contour K.
  • the combed and separated fibers 11 freed from the dirt 12 are carried into the region of the fiber parallelization segment 15 as a result of the air flow, for example due to the negative pressure on a spinning rotor in the spinning device. There they are parallelized and stretched by the parallelization elements 16. Fibers prepared in this way deliver a particularly good spinning result. Especially when fibers are curved and tend to get caught, they are stretched and separated by the paralleling elements and optimally prepared for the spinning process.
  • Fig. 2 shows the position of the fiber parallelization segment 15 within the wall of the housing 1 of the resolver.
  • the housing is shown in perspective, the opening roller as well as the feed trough and the feed roller are omitted.
  • the fiber parallelization segment 15 extends.
  • the parallelization elements 16 lie in parallel rows next to one another and their tips 16 'are aligned with the inner contour I of the housing 1.
  • FIG. 3 shows the longitudinal section through a fiber parallelization segment, the design of which corresponds to the exemplary embodiment in FIG. 1.
  • a part of the wall of the housing 1 is shown between the dirt separation opening 13 and the outlet opening 17 for the fibers in the fiber feed channel.
  • the recess A in the wall of the housing 1 has a circular contour K.
  • the parallelization elements 16 are located in this recess A. They are sawtooth-shaped, the leg of the triangular shape, viewed in the direction of the fiber flight, being longer than the leg which points against the direction of the fiber flight. The inclination of the teeth is therefore exactly the opposite of the inclination of the teeth on the opening roller. This significantly increases the parallel effect of the parallel elements.
  • the tips 16 'of the paralleling elements 16 are aligned with the inner contour I of the housing 1 of the resolving unit.
  • the recess A extends below a secant S, which runs between the intersection points of the contour K with the inner contour I of the housing, namely between the intersection point 19 and the intersection point 20.
  • the center point MK of the contour K lies on a perpendicular perpendicular SM on the secant S. This perpendicular perpendicular SM passes through the center MI of the circular inner contour I of the housing 1.
  • the radius RK of the circular contour K is smaller than the radius RI of the inner contour I of the housing 1.
  • the size of the parallelization elements 16 increases continuously in order to reach its greatest height in the region of the perpendicular perpendicular SM. Thereafter, the size of the parallelization elements 16 decreases continuously in order to decrease to zero again at the intersection 20 of the secant. At this point, the parallelization of the fibers is complete and they enter the outlet opening 17 of the fiber feed channel 18.
  • FIG. 4 shows a further embodiment of a fiber parallelization segment 15.
  • a perspective view of the housing 1 can also be seen here with the feed part broken away and the feed roller omitted.
  • a fiber parallelization segment 15 extends.
  • the recess A ' is formed by penetrating the wall of the housing 1 through the contour K' of a ball, the center of which MK 'on a Center perpendicular SM 'is located on a maximum secant S' and the center perpendicular MS 'goes through the center line MI of the cylindrical inner contour I of the housing 1.
  • the fiber parallelization segment 15 begins with a tip and runs ever wider and deeper apart then then continuously decrease again in the circumferential direction of the inner contour I of the housing 1 after exceeding the maximum secant S '. Also in the present case, the tips of the parallelization elements 16 'are aligned with the inner contour I of the housing 1. The height of the parallelization elements 16 thus decreases continuously towards the edges of the fiber parallelization segment 15.
  • FIG. 5 shows the embodiment of the fiber parallelization segment according to FIG. 4 in the section shown there.
  • the opening roller 2 is inserted into the housing 1.
  • the opening roller 2 with its opening set 3 is mounted with its shaft 4 in the housing 1.
  • the opening roller 2 on its circumference opposite wall of the housing 1 has the recess A ', which was described in the embodiment of FIG. 4.
  • the recess A ' cuts a segment of a circle from the wall of the housing 1. It is limited by the inner contour I of the housing 1 and cuts these in points 21 and 22.
  • the secant S' coincides here with the inner contour I of the housing on average.
  • On the perpendicular perpendicular SM 'of the secant S' is the center MK 'of the contour K'.
  • the perpendicular perpendicular SM ' is at the same time radius RI of the inner contour of the housing. This radius RI is larger than the radius RK 'of the contour K' of the recess A '.
  • the set 3 of the opening roller 2 are opposite the parallelization elements 16. Their tips 16 'are aligned with the inner contour I of the housing 1.
  • the parallelizing elements are largest in the region of the recess A', which is opposite the central circumference of the opening roller 2. Most of the fibers are usually located in this area, so that the desired parallelization effect occurs more intensely there.
  • the fiber parallelization segment In the area of the highest amount of fibers, in the area of the center line of the opening roller, the fiber parallelization segment has its greatest extent in the circumferential direction on the inner contour of the housing seen.
  • spheres, ellipsoids, paraboloids or hyperboloids can be used as rotational bodies.
  • the tools for producing the desired contours are shaped like the rotationally symmetrical bodies when the paralleling elements are eroded out of the wall, ground out or milled out.
  • needles in the recess are aligned concentrically with the center line of the housing contour.
  • a fiber parallelization segment can also be arranged between the feed opening 8 and the dirt separation opening 13.
