Definitions

  • the invention relates to an opening roller for an open-end spinning device according to the preamble of claim 1.
  • opening rollers for open-end spinning devices are known in various embodiments and for example described in DE 197 12 880 A1.
  • an opening roller is also known, the clothing ring of which is arranged directly on the outer rotor of an electric drive.
  • a clothing ring is fixed on the rotatably mounted outer rotor of an opening roller drive by means of a so-called clamping set.
  • Such a clamping set which has been tried and tested in mechanical engineering allows a secure and if necessary releasable setting of a clothing ring on a freely rotatable one Component, that is, on a component during assembly the set ring cannot be secured against rotation, however, such a clamping set is relatively expensive and expensive construction element.
  • the Invention based on the object of creating an opening roller in which the clothing ring easily and quickly on a free rotatably mounted component of the opening roller can be fixed.
  • the torque-free quick release device has the particular advantage that it is a problem It is also possible to replace a clothing ring if the component receiving the clothing ring is freely rotatable stored, that is, not fixed against rotation can.
  • the quick release device according to the invention provides also a very inexpensive and safe Fasteners represents that without the use any tool is necessary, can be used.
  • Such a torque-free one is particularly advantageous Quick release device can be used, for example, if, as in Claim 2 set out as a so-called opening roller drive Outrunner is used. That is, if the Set ring directly on the outside runner Rotor of an opening roller drive is to be determined and the freely rotatable rotor cannot be fixed.
  • the quick release device has, as described in claim 3, two eccentric clamps which act on a spring element, preferably a plate spring.
  • a spring element preferably a plate spring.
  • An axial force component is transmitted to the flanged disk via the plate spring, which is supported on a flanged disk of the opening roller, which ensures that the clothing ring is reliably fixed between the flanged disk and an annular shoulder on the outer rotor of the opening roller drive.
  • the eccentric clamps each have a manually operable actuating tab and at least one eccentrically mounted clamping body.
  • Eccentric clamps designed in this way can, as already indicated above, be operated without the use of a special tool and, due to their translation in their working position, exert such pressure on the plate spring that it is mechanically deformed.
  • the eccentric clamps are connected via a pivot axis to a bolt, which in turn can be fixed on the external rotor of the electric drive via a bayonet catch.
  • a bayonet lock especially if it has the embodiment described in claim 6 or in claim 7, is a simple, but reliable during operation fastener that can be easily solved if necessary.
  • the operating tabs arranged on the eccentric clamps are protected in the operating state of the opening roller in a central recess in the flanged wheel (claim 8).
  • Such a design of the eccentric clamps not only ensures optimal protection of the operating personnel, in particular if the central recess, which is not shown in the present exemplary embodiment, is closed with a cover cap, but the actuating tabs of the eccentric clamps are also easily accessible if necessary. That is, to release the quick release device, only the actuating tabs have to be opened and the bolt of the quick release device fixed by means of a bayonet lock has to be rotated counterclockwise, for example by 45 °.
  • FIG. 1 shows an opening roller drive 4, which is designed as a so-called external rotor. That is to say, the stator 9, which is connected to an opening roller housing 11 via corresponding fastening means, for example screw bolts 10, is encompassed by a rotor, which in this case is referred to as the external rotor 4.
  • the stator winding 12 of the opening roller drive 4 is connected via an energy line 13 to an energy source (not shown).
  • an energy source not shown
  • a set ring 2 is fixed between a flanged wheel 5 and an annular shoulder 6 of the external rotor 3, acted upon by the flanged wheel 5 in the axial direction.
  • the flanged wheel 5 is connected to the external rotor 3 via a torque-free quick release device 7, which acts on a plate spring 8.
  • Flanged wheel 5 and trim ring 2 can also be used as Assembly unit be formed. That means the Centering shoulder 28 of the flanged wheel 5 and the inner diameter 29 of the clothing ring 2 are coordinated so that they form a tight fit with each other, the ensures that these components are installed and removed together can be. The trim ring 2 and the flanged wheel 5 can with each other in an upstream operation get connected.
  • the torque-free quick-action clamping device 7 consists, for example, of a bolt 14 which has radial projections 15 for a bayonet lock 16 and a pivot axis 17.
  • Two actuating tabs 18 are pivotally mounted on the bolt 14.
  • the actuating tabs 18 are connected to the bolt 14 via eccentrically mounted bores in the clamping bodies 19 and the pivot axis 17.
  • the bolt 14 is in turn mounted with its cylindrical body 20 in a corresponding bore 21 of a collar-shaped extension 22 of the external rotor 3, with limited rotation. This means that, as can be seen in particular in FIG.
  • the actuating tabs 18 of the eccentric clamps 26 of the quick release device 7 are pivoted into the position indicated in FIG.
  • the eccentric clamps 26 are then rotated via the actuating tabs 18, for example counterclockwise, until the radial projections 15 on the bolt 14 of the quick-action clamping device 7 correspond to the axial grooves 23 in the collar-shaped extension 22 of the external rotor 3.
  • the quick release device 7 can then be pulled out of the bore 21 of the collar-shaped extension 22 of the external rotor 3 and the flanged wheel 5 and the clothing ring 2 can be removed. No tools are required to carry out the activities described above.
  • Reinstalling a new clothing ring 2 is done in the reverse order. That is, after a new clothing ring 2 has been pushed onto the outer circumference 27 of the outer rotor 3 of the electric drive 4, the flanged disc 5 is positioned and the plate spring 8 is inserted into the central recess 25 of the flanged disc 5. Then the quick release device 7 is mounted. This means that the cylindrical body 20 of the bolt 14 with its radial projections 15 is inserted into the bore 21 of the collar-shaped projection 22 of the external rotor 3 in such a way that the projections 15 slide into the axial grooves 23.
  • the bolt 14 is then rotated clockwise by means of the actuating tabs 18, which leads to a fixation of the quick release device 7 on the external rotor 3 of the electric drive 4. Subsequently, the actuating tabs 18 are pivoted outward about the pivot axis 17. During this pivoting, the eccentrically mounted clamping bodies 19 of the eccentric clamps 26 act on the plate spring 8, which in turn presses the flanged disc 5 against the clothing ring 2 and thereby locks it in a force-locking manner.
  • the torque-free quick release device 7 described above not only enables a problem-free and fast Replacing clothing rings 2, but also provides one very inexpensive and safe fastening device.
  • eccentric clamps 26 it is possible for the eccentric clamps 26 not two, as explained in the exemplary embodiment Have clamp body 19, but that each Eccentric clamp 26 only one clamp body 19 for loading the Disc spring 8 is provided.
  • Belleville spring 8 a comparable spring element, e.g. a Coil spring or the like, is used instead of one Belleville spring 8 .
