Definitions

  • the present invention relates to an open-end spinning device with an opening roller housing, an exchangeable spinning rotor, a rotor cover assigned to the spinning rotor and with a divided fiber feed channel extending from the opening roller housing to the rotor cover, the first part of which is located in the opening roller housing and the second part of which is cast into the rotor cover and a method for producing such a device.
  • spinning rotors can be used in a spinning device, the rotor lid then also having to be adapted accordingly to the spinning rotor (DE-OS 2.130.582). So that the fibers can get into the spinning rotor properly, the second part of the fiber feed channel must be arranged at an angle to the first part of the fiber feed channel for certain rotor sizes.
  • This type of design means that the spinning device is very structurally bound with regard to the relative arrangements of the spinning rotor and opening roller housing, rotor size, etc., and there are also disadvantages in terms of flow technology.
  • the object of the invention is therefore to provide an open-end spinning device and a method which allow adaptation to different rotors and rotor diameters in a simple manner with unchanged arrangement of rotor housing and opening roller.
  • the second part of the fiber feed channel has two longitudinal sections within the rotor lid, the center lines of which form an obtuse angle.
  • this angle is so small that the fiber transport is not significantly impaired, so that with an unchanged relative arrangement of the spinning rotor and opening roller, a wide variety of rotor shapes and sizes can be used and one and the same open-end spinning device also spinning different fibers different stack lengths possible, so that a great universality is achieved.
  • the two longitudinal sections have their smallest cross section at the transition point from the first longitudinal section to the second longitudinal section and face in the direction expand to their opposite ends.
  • Such a configuration forms the prerequisite for the fiber feed channel to be produced with the aid of a divided core, as a result of which the second length section can be arranged at an angle to the first length section if required.
  • the part located in the rotor lid can also take an elongated course under certain circumstances.
  • the first length section has a smaller diameter than the second length section at the transition point.
  • the first length section of the second part of the fiber feed channel is oriented such that the transition angle between the first part of the fiber feed channel and the first length section of the second part of the fiber feed channel and the transition angle between this first length section and the second length section are essentially the same size are, wherein the second length section is oriented according to the desired fiber feed direction in the spinning rotor.
  • a rotor lid causes gentle fiber transport and is also easy to manufacture by casting or injection molding.
  • the transition angles between the first and the second part of the fiber feed channel and the first and the second length section of the second part of the fiber feed channel lie in different planes.
  • the inlet mouth of the first longitudinal section of the second part of the fiber feed channel has a cross section which essentially corresponds to the cross section of the outlet mouth of the first part of the fiber feed channel.
  • the inlet cross-section in the first part of the fiber feed channel is essentially only as large as the cross-section of the free space between the opening roller and the opening roller housing immediately before the inlet opening of the fiber feeding channel.
  • the invention provides for two cores to be introduced into the casting mold and for their end faces to be in mutual contact, the cores being so dimensioned be that they have their smallest cross-section in the area of their mutual contact, and that the cores are pulled out of the fiber feed channel in opposite directions after completion of the casting.
  • the subdivision of the cores forms the prerequisite for the fiber feed channel in the rotor lid to be subdivided into two length sections which differ in shape and / or arrangement from the first length section of this fiber feed channel in the rotor lid.
  • this second length section can have a shape or orientation in comparison to the first length section such that a one-piece core could no longer be pulled out of the rotor lid in the opposite direction to the later fiber transport direction.
  • the invention provides that the two cores are arranged with respect to one another in such a way that their center lines enclose an obtuse angle for the casting process. In this way, a fiber feed channel part is formed in the rotor lid, which is bent at an obtuse angle, so that the fibers enter the spinning rotor in the desired direction.
  • the core which forms the later feed-side first longitudinal section of the fiber feed channel is preferably given a shape which decreases in cross section. Since the fibers cannot be accelerated as quickly as the air transporting them, it is preferably provided in a further embodiment of the invention that the core, which forms the later exit-side second longitudinal section of the fiber feed channel, is given a shape with a substantially constant cross section. In this way, the fibers are given the opportunity to be accelerated up to the speed of the air transporting them before they reach the fiber collecting surface of the spinning rotor.
  • the basic aim is to deflect the air flow transporting the fibers as little as possible so that the fiber orientation is not impaired. For this reason, in a further embodiment of the method according to the invention, if a deflection is unavoidable, it is advantageously provided that the core for the second length section of the second part of the fiber feed channel, which forms the later exit side of the fiber feed channel, corresponding to the later fiber feed direction in the spinning rotor while the core is oriented for the first length of the second part of the fiber feed channel so that the angle between the centerlines of the two cores is substantially the same as the angle between the direction in which the fibers later operate the first part of the fiber feed channel, and the center line of the later feed-side first length section of the second part of the fiber feed channel.
  • the required redirection is divided into two places, so that each individual redirection is so slight that it has no disruptive effects on the fiber transport.
  • the present invention makes it possible in a simple manner that the fiber feed channel can be formed in the rotor lid by casting and injection molding even if it does not extend in a straight line, but has an angled shape. In this way, even if spinning rotors of different diameters or shapes are to be used in a spinning device, rotor lids can be used which are equally inexpensive to manufacture. The complicated adjustment of tubes in the rotor lid is no longer necessary. This also eliminates sources of error that could occur with this adjustment.
  • Figure 5 shows an open-end spinning device with a spinning rotor 1, which is arranged in a conventional manner in a housing 2.
  • This housing 2 which is produced in the casting or injection molding process, is covered by a rotor cover 3 which is also produced in the casting or injection molding process and which contains a fiber feed channel 4 and a thread take-off tube 5.
  • the fiber feed channel 4 contains a first part 40, which is formed in an opening roller housing 6, and a second part 41, which is located in the rotor cover 3.
  • a delivery device 61 which in the exemplary embodiment shown consists of a delivery roller 610 and an elastically loaded feed trough 611 assigned to it.
  • the opening roller 60 is supplied in a known manner with a sliver 7, which is broken up into fibers 70 by the opening roller 60 and is fed in this form to the spinning rotor 1, where the fibers 70 are deposited in the form of a fiber ring (not shown), which is continuously incorporated into the end of a thread 71, which in turn leaves the spinning rotor 1 through the thread take-off tube 5.
  • the quality of a thread 71 essentially depends on the nature of the fibers 70 that have accumulated in the fiber collecting groove of the spinning rotor 1.
  • the fibers are therefore subjected to a fiber stretching process during their transport from the opening roller 60 to the spinning rotor 1. Since the part 40 of the fiber feed channel 4 located in the opening roller housing is relatively short, the fiber stretching takes place essentially in the second part 41 of the fiber feed channel 4.
  • the second part 41 of the fiber feed channel 4 is divided into two length sections 410 and 411, both of which are arranged in the rotor cover 3.
  • the first length section 410 tapers in the fiber transport direction (see arrow P).
  • the air transporting the fibers is accelerated in this way and in doing so also accelerates the fibers 70 floating in it, as a result of which these are both stretched and parallelized.
  • the fibers 70 have a greater inertia than the air, so that they cannot reach the same speed in this length section 410 as the transporting air.
  • the second length section 411 adjoining the first conical length section 410 has a substantially cylindrical shape.
  • the air does not change its speed significantly in this second section 411, while the fibers 70 in this section 411 undergo post-acceleration.
  • the fibers 70 have the opportunity, during their adaptation to the air speed, to calm down in their position.
  • FIG. 1 shows part 41 of a previously common fiber feed channel 4.
  • the second length section 411 is an extension of the first length section 410.
  • a core 8 can be inserted into the mold , which extends over the entire length of part 41 of the fiber feed channel 4 and later opposite to The fiber transport direction, ie opposite to the arrow P, can be pulled out of the second part 41 of the fiber feed channel 4 located in the rotor cover 3.
  • this second part 41 of the fiber feed channel 4 has a diameter d 1 on the inlet side which is larger than the diameter d 2 at the transition from the first length section 410 to the second length section 411.
  • the diameter d 2 in turn is larger than the diameter d 3 at the outlet of the fiber feed channel 4 from the rotor lid 3, ie at the outlet end of the second length section 411.
  • Figure 2 shows another known embodiment of a fiber feed channel, in which the second length section 411 is also in alignment with the first length section 410, even if the center line M 1 of the first length section 410 is arranged at an angle to the center line M 2 in the second length section 411.
  • the use of a core 80 extending over the entire length of the part 41 of the fiber feed channel 4 is possible, since the subsequent removal of the same from the cast rotor cover 3 does not pose any problems.
  • the part 41 of a fiber feed channel 4 shown in FIG. 3 differs significantly from the designs of such a second part 41 of a fiber feed channel 4, as was described above using the example of FIGS. 1 and 2.
  • the diameter d 1 at the entry end of the first length section 410 is larger than the diameter d 2 at the transition point S 2 from the first length section 410 to the second length section 411, but on the other hand the diameter d 3 at the exit of the second length section 411 is also larger than the diameter d2
  • the center lines M1 and M2 of the two longitudinal sections 410 and 411 are arranged at an obtuse angle to one another, but the longitudinal section 411 is overall so at an angle to the length Section 410 arranged that the peripheral wall of the second length section 411 is no longer arranged in the extension of the peripheral wall of the first length section 410 and also does not run into the part 41 of the fiber feed channel 4.
  • a one-piece core 8 or 80 could therefore not be pulled out of the rotor lid 3 at all, so that with such a shape of a fiber feed channel 4 no one-piece core 8 (according to FIG. 1) or 80 (according to FIG. 2).
  • two cores 81 for the first length section 410) and 82 (for the second length section 411) are therefore provided.
  • these cores are introduced into the casting mold (not shown) in such a way that their end faces 810 and 820 are brought into mutual contact.
  • the cores 81 and 82 have in their system area, i.e. at the transition point S2 from length section 410 into length section 411, its smallest cross section, which corresponds to the diameter d2.
  • the cores 81 and 82 are pulled out from the part 41 of the fiber feed channel 4 in opposite directions.
  • a burr is formed at the transition point S2, it can be removed by polishing, sandblasting, etc.
  • the first length section 410 at the transition point S2 has a cross section d5 which is smaller than the input cross section d6 at this point S2. This facilitates deburring with the aid of a reamer, so that it is ensured that no burr protrudes into the fiber path in the finished fiber feed channel 4.
  • each of these diameters is to be understood as a cross section which can also deviate from a circular shape.
  • the only decisive factor is that the dimensions in the region of the cross section marked with diameter d 1 are larger transversely to the longitudinal extent than the corresponding dimensions in the region of the cross section marked with the diameter d 2.
  • the same also applies in a similar way to the cross sections with the diameters d2 and d3 Marked are.
  • the part 41 in the area of the inlet cross section marked with d 1, the part 41 has a substantially rectangular or otherwise shaped elongated cross section, while the cross sections in the area of the areas marked as diameters d 2 and d 3 usually have a circular shape.
  • the mutual arrangement of opening roller housing 6 and housing 2 for the spinning rotor 1 is usually chosen such that the fiber feed channel 4 is essentially one at the usual average rotor sizes can take a straight course. In this way, after leaving the opening roller 60, the fibers reach the inside of the spinning rotor 1 in a straight line.
  • the fiber transport path it is necessary to modify the fiber transport path in order to achieve an optimal feeding of the fibers 70 onto the inner peripheral wall of the spinning rotor 1 .
  • the arrangement of opening roller housing 6 and housing 2 for the spinning rotor 1 cannot be changed.
  • the rotor cover 3 which is also exchanged in adaptation to the selected rotor shape or size, contains such a second part 41 of the fiber feed channel 4, the two length sections 410 and 411 of which also depend on the selected rotor size or shape arranged differently in the rotor lid 3 are.
  • the second length section 411 receives an orientation that is optimally matched to the spinning rotor 1 in such a way that the fibers 70 reach the inner circumferential wall of the spinning rotor 1 in the desired direction and at the desired location.
  • the two longitudinal sections 410 and 411 to each other so that their center lines M1 and M2 include an obtuse angle ⁇ (Fig. 3 and 4) or ⁇ (Fig. 6). Accordingly, the two cores 81 and 82 are to be inserted into the mold, not shown, for the casting.
  • the first length section 410 is designed as a connecting section between the first part 40 of the fiber feed channel 4 and the second length section 411 of the second part 41 of the fiber feed channel 4 and is oriented so that the fibers 70 on their way from the opening roller housing 6 to the spinning rotor 1 are as possible experienced minor redirection. Therefore, a necessary deflection of the fiber transport path to the two transition points S1 and S2 (see Fig. 4) between the first part 40 of the fiber feed channel 4 and the second part 41 of the fiber feed channel 4 on the one hand and the first length section 410 and the second length section 411 of the second part 41 of the fiber feed channel 4 on the other hand divided.
  • angles ⁇ and ⁇ are entered.
  • the angle ⁇ between the center line M of the first part 40 and the center line M1 of the first longitudinal section 410 of the second part 41 of the fiber feed channel 4 is chosen so that it is essentially as large as the angle ⁇ between the center lines M1 and M2 of the two Length sections 410 and 411 of the second part 41 of the fiber feed channel 4.
  • the core 82 for the second length section 411 corresponds to the direction in which the fibers 70 later spin into the spinning mode rotor 1 should arrive, oriented, while the core 81 is oriented for the length section 410 so that the angle ⁇ between their center lines M1 and M2 is substantially as large as the angle ⁇ between the direction (center line M) in which the fibers 70 later in operation from the first part 40 of the fiber feed channel 4 into the second part 41 of the fiber feed channel 4, and the center line M1 of the first length section 410 of the second part 41 of the fiber feed channel 4th
  • the fiber feed channel 4 is generally not enough, however, for the fiber feed channel 4 to be angled only in a single plane.
  • the fiber feed channel 4 must also be angled in a second plane. This is necessary so that the feed direction of the fibers 70 is as far as possible parallel to the direction of rotation (see arrow R) of the spinning rotor 1.
  • the angles ⁇ and ⁇ between the first part 40 and the second part 41 of the fiber feed channel 4 and the first length section 410 and the second length section 411 of the second part 41 of the fiber feed channel 4 are chosen to be as large as possible.
  • the fiber feed channel 4 is thus angled in two different planes, so that the angles ⁇ and ⁇ as well as ⁇ and ⁇ result in other angle sizes, which, however, are not shown for the sake of a simple illustration.
  • FIGS. 5 and 6 each show the arrangement of the fiber feed channel 4 with a medium rotor size with a solid line, while with a dashed line the fiber feed channel for a spinning rotor 1 with a large diameter and with a dash-dotted line the fiber feeding channel 4 for a spinning rotor 1 a small diameter is shown.
  • the transition point S1 between the first part 40 and the second part 41 of the fiber feed channel is formed by the separation point between the opening roller housing 6 and the rotor lid 3.
  • the diameter d 1 (cross-sectional area) at the entry into the first length section 410 of the second part 41 of the fiber feed channel 4 is slightly larger is as the outlet cross-section (d4) at the outlet end of the first part 40 of the fiber feed channel 4.
  • the cross section d 1 at the entrance to the second part 41 of the fiber feed channel 4 often had to be significantly larger than the cross section d4 at the outlet from the first part 40 of the fiber feed channel 4, it is now possible to choose the cross section (diameter d1) so that it is essentially as large as that Cross section (diameter d4) at the outlet from the first part 40 of the fiber feed channel 4. Die s has a favorable influence on the fiber orientation, since the speed of the air as a transport medium for the fibers 70 is not significantly impaired.
  • the inlet cross section Q2 in the first part 40 of the fiber feed channel 4 is substantially the same size as the cross section Q1 of the free space between the opening roller 60 and the opening roller housing 6 immediately before the beginning of the fiber feeding channel 4th .
  • the device can be modified in various ways, in particular by exchanging features by equivalents or by other combinations.
  • the angles ⁇ , ⁇ between the two parts 40 and 41 of the fiber feed channel can be selected according to needs, as can the relative arrangement of the two longitudinal sections 410 and 411 of the second part 41 of the fiber feed channel.
  • the shapes of the individual parts 40 and 41 of the fiber feed channel can also be different.
  • the second length section 411 can have a shape which is different in length in relation to the first length section and thereby widen more or less so that the core 82 can be pulled out of it during manufacture.
  • the extension of the length section 411 is chosen to be as small as possible so that it has practically no effect on the air speed.
  • the core 82 for the second length section 411 has a shape with an essentially constant cross section in such a way that it is still possible to pull the core 82 out of the length section 411 without difficulty.
  • the conical length section 410 can be produced by casting, a suitable insert for forming this length section 410 possibly being cast in, while the length section 411 is produced by drilling.
  • the part 41 of the fiber feed channel 4 located in the rotor lid 3 is cast in its entirety, since this is particularly advantageous in terms of production.
