Definitions

  • the present invention relates to an open-end spinning device with a stationary spinning element, a stationary opening roller housing and a fiber feed channel leading from the opening roller housing to the spinning element, which is divided into a stationary and a movable part by a parting plane which is at an angle greater than 5 o is, the fiber feeding channel is arranged to the moving direction of the movable part further cooperates with a moveable cover for the spinning element which has a stop with the stop at a spinning element, the female housing.
  • the stationary part of the fiber feed channel is provided in an opening roller housing which is screwed onto the machine frame (DE-OS 2.130.688).
  • the movable part of the fiber feed channel is located in a rotor lid, which can be swiveled around a vertical axis in and out of the working position. It slides on the surface of the opening roller housing that forms the separating surface of the fiber feed channel.
  • the cover is guided on its pivot axis so that it covers the rotor housing properly. In this way, a seal between the two longitudinal sections of the fiber feed channel cannot be achieved, so that secondary air penetrates into the fiber feed channel.
  • both the cover and the opening roller housing with the ring seal are each pivotally mounted about an axis and control via a pressure cam is provided such that the opening and closing movement of the cover, the opening roller housing is pivoted so far that the cover without Touching the ring seal can assume its closed position and only in the closed position the opening roller housing is pivoted back against the ring seal.
  • the object of the present invention is therefore the exact fixing of the movable feed channel part with the cover relative to the two connection elements spinning rotor or friction rollers on the one hand and fiber feed channel in the opening roller housing on the other hand. With this fixation, the sealing of the duct separation point is a secondary problem.
  • the solution according to the invention is that a catch is provided which secures the cover positioned in its working position in relation to the spinning element due to the cooperating stops, and that the fiber feed channel has an elastic separating surface in the separating plane. It is thus achieved in a simple manner that the opening and closing of the rotor housing or friction roller housing is made possible with a stationary opening unit by a single pivoting movement of the movable fiber feed channel about a single pivot axis. This not only considerably simplifies the design with regard to the mounting of the opening roller housing and the connection of the drives for the opening roller and the feed roller, but also simple assembly and adjustment of the individual elements to one another and sealing of the duct separation point is achieved, which is positive for the whole Spinning properties of the spinning device affects.
  • the mouth of the feed channel is positioned exactly to a fraction of a millimeter in relation to the friction rollers or in relation to the wedge gap.
  • this important fixation is carried out directly in relation to the spinning element (friction rollers or spinning rotor), while any differences that may arise at the point of separation of the fiber feed channel are compensated for by an elastic separating surface. This ensures both a fixation of the part of the fiber feed channel located in the cover and a sealing of the separation point of the fiber feed channel.
  • the claimed orientation of the parting surface ensures that the movement of the length section during the time during which its end is in contact with the ring seal has a movement component perpendicular to the parting plane. This causes a reduction or total avoidance of sliding movements of the longitudinal section relative to the elastic separating surface, which increases the service life of the elastic separating surface leads.
  • No pivotable housing, no guide ramp and no control for the opening and closing process is required, so that a device that is much simpler and thus also cheaper is achieved compared to the prior art.
  • the elastic interface can be designed differently, e.g. B. as an elastic or elastically mounted plate; there is preferably an elastic ring seal in the separating surface.
  • the elasticity of the separating surface is achieved by the ring seal, while the surface carrying the ring seal itself can be rigid.
  • this element is preferably located on the stationary channel part.
  • a seal is required both between the movable part of the fiber feed channel and its stationary part and between the movable part and the housing receiving the open-end spinning element (spinning rotor, friction spinning elements, etc.). It has been found to be advantageous due to the usual relative positions of the open-end spinning element and opening roller housing and the resulting orientation of the fiber feed channel if the angle of inclination between the separating surface and the direction of movement of the movable longitudinal section is greater than 5 o , but not greater than 45 o .
  • the movable part of the fiber feed channel can be moved in any way relative to the separating surface and the stationary part of the fiber feed channel.
  • the cover can be pivoted about a pivot axis which extends horizontally in a plane parallel to the collecting groove plane of the spinning rotor.
  • the cover can preferably be pivoted about a pivot axis which extends perpendicular to the axes of the friction spinning elements parallel to the plane defined by the axes of the two friction spinning elements.
  • the cover in order to completely avoid movement components parallel to the separating surface, it can be provided that the cover can be pivoted about a pivot axis which is located in the plane of the separating surface of the two parts of the fiber feed channel.
  • a guide pin is advantageously assigned to the cover, which aligns the movable part of the fiber feed channel during its movement into its working position relative to the stationary part parallel to the pivot axis. In this way, an exact positioning of the fiber feed channel with respect to the spinning elements is achieved with a secure sealing of the fiber feed channel.
  • the fiber feed channel is achieved in that the stop and / or the guide pin is located at the end of the surface of the cover which is in contact with the housing and faces away from the separating surface.
  • the subject matter of the invention makes it possible, in the case of a divided fiber feed channel, to easily fix the movable feed channel part in the cover with respect to the connection elements spinning element (spinning rotor or friction rollers) and stationary fiber feed channel part.
  • undisturbed fiber transport is achieved without the opening roller housing having to be pivotably mounted and without the need for guide ramps between the opening roller housing and the cover for the spinning unit which carries the movable part of the fiber feed channel.
  • a simpler and more robust device is thus created, which is therefore also less prone to failure.
  • a long service life of the elastic or elastically mounted element is also achieved, since the movable part of the fiber feed channel has a movement component perpendicular to the separating surface when it runs onto the elastic separating surface.
  • the open-end friction spinning device shown in FIG. 1 contains two rotationally symmetrical driven friction spinning elements 1, at least one of which is perforated.
  • this perforated friction spinning element is designed as a roller.
  • At least the perforated friction spinning element 1 is connected to a vacuum source via a suction pipe 10.
  • the two friction spinning elements 1 - only one of which is visible in FIG. 1 - are arranged in a housing 16 and are driven in the same direction by a tangential belt 2.
  • the friction spinning elements 1 are preceded by a fiber feed device 9 (see FIG. 2) and a opening roller 3.
  • the opening roller 3 sits in a housing 30 and is driven by means of a tangential belt 33 via a whorl 32 seated on its axis 31.
  • a fiber feed channel 4 extends from the opening roller 3 into the wedge gap (not shown) between the two friction spinning elements 1.
  • the fiber feed channel 4 is divided into a stationary part 40 arranged in the housing 30 of the opening roller 3 and a movable part 41.
  • the movable part 41 is arranged in a pivotable cover 5, which covers the wedge gap between the friction spinning elements 1.
  • the cover 5 is mounted on a carrier 50 mounted on the housing 30 by means of a pivot axis 51.
  • the pivot axis 51 is located in front of these in relation to the direction of transport of the fiber material through the friction spinning elements 1 and extends perpendicular to the axes of the friction spinning elements and parallel to the plane 13 through these axes.
  • the cover 5 with the movable part 41 of the fiber feed channel 4 can be brought from the working position shown into a maintenance position in which the wedge gap between the friction spinning elements 1 is freely accessible.
  • the separating surface 6 between the two parts 40 and 41 of the fiber feed channel 4 is also exposed, so that from here both the part 40 and the part 41 of the fiber feed channel 4 can be cleaned.
  • annular seal 60 which is mounted in a groove 61 of the housing 30 and extends slightly beyond the groove 61.
  • the separating surface 6 is placed in the embodiment shown so that the pivot axis 51 for the cover 5 and the movable part 41 of the fiber feed channel 4 is in the separating surface 6. Thereby, the direction of movement (double arrow 7) of the ring seal 60 oriented end facing the movable portion 41 of the fiber feeding channel 4 in an angle ⁇ of 90 o to the separating surface. 6
  • Fig. 1 shows that the cover 5 with the movable part 41 of the fiber feed channel 4 is assigned a stop 8 which limits the movement of the cover 5.
  • This stop consists of a first element 53 on the cover 5 and a second element 82 on the housing 16, with the aid of which the cover 5 and thus the movable part 41 of the fiber feed channel 4 can be positioned exactly with respect to the friction spinning element 1.
  • the cover 5 is secured in its working position by a catch 83.
  • the open-end friction spinning device works in the usual way.
  • a sliver (not shown) is fed to the opening roller 3 with the aid of the aforementioned fiber feed device 9 (FIG. 2), which loosens the sliver into individual fibers.
  • the individual fibers pass through the fiber feed channel 4 into the wedge gap between the two friction spinning elements 1.
  • the fibers are bound into the end of a thread, which is continuously drawn off in a known manner by means of a pair of draw-off rollers, not shown.
  • the wedge gap between the friction spinning elements 1 or the separating surface 6 of the fiber feed channel 4 is to be made accessible for maintenance purposes, this is done by pivoting the cover 5 about the pivot axis 51.
  • the chosen relative arrangement of the pivot axis 51 and the separating surface 6 ensures that the Cover 5 with the movable part 41 of the fiber feed channel 4 is moved during its opening movement (see direction of movement indicated by double arrow 7) along a plane through the fiber feed channel 4 and perpendicular to the separating surface 6. There are therefore no sliding movements between the cover 5 and the ring seal 60 mounted in the housing 30. As a result, the ring seal 60 has a long service life.
  • the cover 5 With its closing movement, the cover 5, with its stop element 53, comes into contact with the stationary stop element 82 of the housing 16, as a result of which the position of the cover 5 relative to the friction spinning elements 1 arranged in the housing 16 is precisely defined. Any differences that may arise at the separation point of the fiber feed channel 4 are compensated for by the elastic separation surface 6. With exact positioning of the movable part 41 of the fiber feed channel 4 to the friction spinning elements 1, a perfect seal between the two parts 40 and 41 of the fiber feed channel 4 is achieved.
  • the ring seal 60 is dimensioned and has such elasticity that it largely or even completely absorbs tangential movement components in the period between the contact between the cover 5 and the ring seal 60 and the contact of the cover 5 at the stop 8. This avoids sliding friction between the cover 5 with the movable part 41 of the fiber feed channel 4 and the ring seal 60, which leads to an increased service life of the ring seal 60.
  • the ring seal 60 is either, as shown, embedded in a groove 61 or, differently, is glued to a surface ending in the separating surface 6 or is fastened in some other way.
  • a guide pin 15 is provided on the housing 16, which engages in a recess 52 in the cover 5.
  • the movable part 41 of the fiber feed channel 4 is in this case in its working position not only sealed and fixed with respect to the stationary part 40 of the fiber feed channel 4, but also with respect to the housing 16.
  • the angle ⁇ between the separating surface 6 and the direction of movement (double arrow 7) of the movable part 41 of the fiber feed channel 4 is greater than 5 o , but not greater than 45 o .
  • the movement of this movable part 41 of the fiber feed channel 4 has both a movement component perpendicular to the separating surface 6 and to the parting plane between the movable part 41 of the fiber feed channel 4 and the housing 16 for the friction spinning elements 1.
  • the pivot axis for the cover 5, deviating from the embodiment shown, can also be behind the friction spinning elements 1 with respect to the material transport direction.
  • the stop and the guide pin from FIG. 1 can also be combined with one another, as shown in FIG. 4.
  • a bolt 87 with a conical head 88 is introduced into a threaded bore 17 provided in the housing 16, the bolt 87 being secured in the respective position by a lock nut 89.
  • the head 88 engages in a conical bore 54 of a plate 55.

  • two lock nuts 58 and 59 are screwed onto the threaded bolts 56 and secured against one another by locks.
  • the bores 57 in the cover have a larger diameter than the threaded bolts 56, so that the plate 55 can be adjusted transversely to the axis of the bolt 87.
  • the bolt 87 can thus be adjusted in the direction of movement of the cover 5, while this plate 55 can be adjusted transversely thereto in order to align the fiber feed channel 4 parallel to the collecting surface (plane 13).
