Definitions

  • the invention relates to an open-end spinning device according to the preamble of claim 1.
  • open-end spinning devices have long been known, in which the various spinning components are arranged in a spinning box frame, which in turn is composed of several individual parts.
  • Open-end spinning devices have a spin box, which consists of at least two fixable on the machine base frame of a textile machine side parts, at least two upper bracing elements and at least one lower spacer.
  • the side parts and the bracing elements are connected to each other via a plurality of bolts, wherein the individual components are elaborately aligned via Plangebohrung / dowel pin connections.
  • the DE 197 17 737 A1 describes such Spinnboxrahmen whose components are joined in the laser welding process.
  • a spinning box frame in itself already constitutes a relatively expensive component, which serves only to serve the various spinning components of an open-end spinning device To store exactly positioned and set on the machine frame of a textile machine.
  • the DE 21 30 688 A1 describes such an open-end spinning device.
  • the rotor housing is defined by lateral flanges on the upper leg of a U-shaped carrier and has a rear recess in which a single-motor driven spinning rotor is mounted.
  • the front of the rotor housing is closed by a lid, which in turn is pivotally fixed to the rotor housing.
  • a sliver disassembling device is attached to the end face of the lower leg of the U-shaped carrier and is operatively connected to the rotor housing via a fiber guide channel.
  • the present invention seeks to develop an open-end spinning device, which is on the one hand inexpensive to produce, and on the other hand it is ensured that the different spinning components can be exactly positioned.
  • the embodiment of the invention Due to the design of the rotor housing as a central, supporting member, the embodiment of the invention has the advantage that can be completely dispensed with a complex spinning box frame for positioning the various spinning components.
  • the rotor housing which can be fastened, for example, via attachment tabs to the machine frame of the textile machine, forms the supporting backbone of the open-end spinning device according to the invention, to which the other spinning components are attached.
  • the single-motor drive for the spinning rotor is screwed directly.
  • Such an arrangement also has the advantage that the transport air, which pneumatically promotes the fibers from the opening device to the spinning rotor and thereby flows through the rotor housing, at the same time also cools the drive of the spinning rotor.
  • the inventive construction also ensures that the spatial allocation of the individual spinning components is maintained to the most accurate and reproducible, for example, in an exchange of individual spinning components at any time, which is extremely important in the interest of a good spin result.
  • the rotor housing is made in an advantageous embodiment as a casting, with aluminum being used as the preferred metallic material.
  • the housing of the electromagnetic drive of the spinning rotor which also has the rear magnetic bearing point for the spinning rotor, can be fixed to the rotor housing by means of bolts which allow the rear wall of the rotor housing to be passed from the front.
  • a housing for the control electronics of the spinning rotor drive is further provided. This housing is directly connected to the housing of the spinning rotor drive.
  • the fixable on the rotor housing carrier preferably consist of a metallic material, such as aluminum.
  • the separately manufactured and provided with mating holes carrier are about corresponding centering pins and bolts matingly fixed to the rotor housing and then form with the rotor housing a quasi one-piece component with respect to the spinning rotor axis exactly positioned pivot axis for the cover element (claim 8).
  • the spinning components arranged in the cover element are therefore always exactly positionable with respect to the spinning rotor.
  • the arranged in corresponding bearings of the carrier sliding bushes correspond, as is known, with adjustable pins on the cover element and allow both easy up and Zuschenken the cover element as well as needed at any time a quick and easy replacement of this component.
  • FIGS. 1 to 3 the open-end spinning device 1 according to the invention is shown in different views.
  • FIG. 1 shows in the direction X the left side, FIG. 2 in the direction X the right side and the FIG. 3 the back of the open-end spinning device. 1
  • the open-end spinning device 1 has, as a central, supporting component, a rotor housing 2 made of a good heat-conductive metal, for example aluminum, on which via dowel pins 16 and bolts 17 in a precise fit carrier 4 are fixed.
  • This trained example as bearing arms carrier 4 have each end equipped with sliding bushings 28 bearing point, which form a pivot axis 5, a cover element 6.
  • the cover element 6, which closes the rotor housing 2 during the spinning operation, has for this purpose an annular seal 22, which bears against the front wall of the rotor housing 2.
  • a sliver disintegrator 23 is integrated, which, as indicated schematically, via a preferably single motor driven opening roller 7 and also a single motor driven sliver feed cylinder 8 has.
  • the single-motor driven spinning rotor 21 is supported by magnetic bearings 24, 25 without contact.
  • Such driven and stored spinning rotors are known in principle and, for example, in the EP 0 972 868 A2 described in relative detail.
  • a housing 14 is connected, which receives the control electronics 15 for the drive 3.
  • the control electronics 15 ensures that the spinning rotor 21 always rotates at the prescribed speed.
  • the rotor housing 2 is also, as usual, via a pneumatic line 10 to a (not shown) Vacuum source connected, which provides the vacuum required during the spinning process.
  • the spinning rotor drive 3 is arranged on the rear wall 26 of the rotor housing 2 and gripped, in particular with reference to the detail Y of Fig. 1 can be seen, a centering projection 29 in the region of the rear wall 26 of the rotor housing second
  • the yarn (not shown) produced during the spinning process in the open-end spinning apparatus 1 is withdrawn from the open-end spinning apparatus 1 via a yarn withdrawal tube 9 and then, as known, wound into a cross-wound bobbin by means of a known rinsing apparatus (not shown).
  • a sliver compressor 19 is arranged on the cover element 6, via which the sliver (not shown) is fed to the sliver opening device 23.
  • FIG. 3 is a rear view of the open-end spinning device 1 according to the invention.
  • 17 carrier 4 are flanged to the rotor housing 2 via dowels 16 and bolts.
  • the carrier 5 have at the end a pivot axis 5 for the cover element 6, which is the suppressible rotor housing 2 closes during spinning operation.
  • the drive 3 for the spinning rotor 21 can be seen, which in turn is connected to the housing 14 for the control electronics 15.
  • the single drive 18 for the sliver feed cylinder 8 and the bearing bracket 20 are arranged for the opening roller 7 formed as an external rotor.
  • FIG. 4 shows a perspective view of a designed as a central, supporting component, preferably made of aluminum rotor housing second
  • carrier 4 are fixed in register on the back of the rotor housing 2 in the outer region via dowels 16 and bolts.
