Definitions

  • the He indation relates to a device for producing a spun thread from a Stapelfase ⁇ / erband, with an air nozzle downstream of a delivery device for the staple fiber association, which is arranged on a holder which, together with the air nozzle unit, can be pivoted away from the delivery device about a pivot axis.
  • a device of this type is known from DE 40 20 049 C2.
  • the known air nozzle unit is arranged on a pivotable holder in such a way that it can be pivoted away from the delivery line by an angle of approximately 30 ° from the delivery device for the purpose of cleaning or inspection.
  • the document mentioned does not contain any information on the mounting of the holder on the swivel axis.
  • the invention is based on the object of being able not only to be able to pivot the air nozzle unit away from the delivery device from its operating position, but also to be able to disassemble it from the pivot axis without any tools.
  • the object is achieved in that the holder and the swivel axis are designed in such a way that the holder together with the air nozzle unit can be removed transversely to the swivel axis after a predetermined swivel angle.
  • a basic solution for such a detachability of a holder from a pivot axis can be found in the non-generic DE 43 04 088 A1.
  • the design according to the The invention enables a secure fixation of the air nozzle unit to the delivery device during operation and still allows easy disassembly without any tools.
  • a continuous swivel axis does not necessarily have to be used. Rather, in an embodiment of the invention, the pivot axis can consist of two stub axles, each of which is arranged on its own bearing block. This is not only favorable in terms of symmetry, but also makes a separate axial securing on the swivel axis superfluous.
  • the pivot axis has an outer contour, which is partially designed as a cylindrical surface, which is interrupted by at least one flat surface in the manner of a secant, and if the holder is provided with a fork-like receptacle which is attached to the fork base the cylindrical surface has a matching hollow cylindrical counter surface, the receptacle having an opening that is smaller than the diameter of the cylinder surface but larger than the distance of the flat surface from the outer contour of the pivot axis.
  • the position of the flat surface determines the swivel angle at which the air nozzle unit together with the holder can be removed transversely to the swivel axis. Disassembly in the operating position is thus effectively prevented.
  • the cylindrical surface of the outer contour can be interrupted secant-like by two flat surfaces arranged parallel to one another, the distance from one another being somewhat smaller than the mouth width of the fork-like receptacle. This enables the holder to be guided securely on the swivel axis during assembly by a total of two guide surfaces.
  • the air nozzle unit is at a distance so that the air nozzle unit can be quickly aligned with the delivery device during operation a stop securing the operating position is assigned from the pivot axis.
  • This stop or an associated contact surface of the air nozzle unit expediently contains a magnet, which then allows the air nozzle unit to be securely fixed in its operating position in a simple manner.
  • FIG. 1 shows a partially sectioned side view of a device according to the invention in the operating position
  • FIG. 2 shows a view of the device in the direction of arrow II in FIG. 1,
  • FIG. 3 shows a perspective illustration of a holder used for the device according to FIG. 1,
  • FIG. 4 shows a perspective illustration for a bearing block which contains the pivot axis assigned to the holder
  • FIG. 5 is a view similar to FIG. 1, the air nozzle unit of the device being pivoted away from its operating position into a disassembly position,
  • FIG. 6 shows the illustration according to FIG. 5 after the air nozzle unit, including its holder, has been removed from the swivel axis transversely to it.
  • the device shown in its operating position in FIG. 1 contains a delivery device 1 for feeding a staple paper to be spun. serverbandes and an air nozzle unit 5, in which the staple fiber association is given the rotation required for spinning a thread.
  • the delivery device 1 contains two delivery rollers 2 and 3, which are arranged at a short distance from the air nozzle unit 5 and which can be the output rollers of an otherwise not shown drafting system. Such a drafting system warps a sliver or a roving in a known manner to form a staple fiber dressing of the desired fineness.
  • the delivery device 1 can alternatively be a pair of clamping rollers of another drafting device or another upstream unit. 4 designates a clamping point at which the staple fiber dressing (not shown in supply direction A) is held clamped before it enters the air nozzle unit 5.
  • the air nozzle unit 5 the design of which is arbitrary, generates its rotation for the thread not to be spun and delivers the thread in the thread draw-off direction B by means of a pair of draw-off rollers, not shown.
  • the air nozzle unit 5 can be designed according to EP 1 217 109 A2.
  • An air nozzle unit 5 contains a feed channel 6 which leads the staple fiber structure to a swirl chamber 7, into which compressed air nozzles (not shown) open and produce a swirl flow which is responsible for the spin twist.
  • the compressed air supplied is then discharged via an exhaust air duct 8, which surrounds a stationary spindle-like component 10 in the form of a ring, in which a thread take-off duct 9 for the spun thread is located.
  • a swirl lock 11 which can be formed, for example, by an edge of a fiber guide surface 12.
  • Such air nozzle Aggregates 5 are therefore known per se and can be designed differently than is described here.
  • the air nozzle unit 5 is arranged on a holder 13 which, together with the air nozzle unit 5, can be pivoted away from the delivery device 1 about a pivot axis 14 if required. This can be necessary, for example, during a maintenance process or, according to this invention, for the purpose of disassembly.
  • the design of the holder 13 and the pivot axis 14 provided for this purpose is described in detail below. It should only be mentioned here that the pivot axis 14 is attached to two bearing blocks, of which only one bearing block 15 is visible in FIG. 1, and that the bearing blocks are provided with bores 16 for attachment to the machine frame.
  • a stop 17 is provided, which is preferably arranged on the machine frame at a distance from the pivot axis 14. This stop 17 or a contact surface 19 of the air nozzle unit 5 can contain a magnet 18 for fast and secure fixing.
  • the pivot axis 14 consists of two stub axles 20 and 21, the configuration of which will be described in more detail later.
  • One stub axle 20 is attached to the already mentioned bracket 15, the other stub axle 21 is attached to a second bracket 22.
  • Both bearing blocks 15 and 22 are fastened to the machine frame 23 by means of the bores 16 mentioned.
  • the two axle journals 20 and 21 of the pivot axis 14 are assigned in a manner to be described in more detail the holder 13, to which the air nozzle unit 5 is in turn attached.
  • a holder 13 is shown in FIG. 3, and a bearing block 22, which corresponds to the other bearing block 14, is shown in perspective in FIG.
  • the stub axle 21, which forms part of the pivot axis 14, has an outer contour 24, which is partially designed as a cylindrical surface 25, see also FIG. 1.
  • This cylindrical surface 25 of the outer contour 24 is interrupted in a secant manner by two flat surfaces 26 and 27 arranged parallel to one another. Although it would suffice to provide only a single flat surface, the configuration with two flat surfaces 26 and 27 is expedient.
  • the stub axles 20 and 21 are assigned a fork-like receptacle 28 of the holder 13.
  • This fork-like receptacle 28 has a fork base 29 which has a hollow cylindrical counter surface 30 which is adapted to the cylinder surface 25.
  • a receptacle 32 is provided for the stub axle 20 and a receptacle 33 of the holder 13 for the other stub axle 21, the two receptacles 32 and 33 being designed as a continuous fork-like receptacle 28 in the present case ,
  • the fork-like receptacle 28 has an internal width x which is smaller than the diameter d of the cylinder surface 25, but somewhat larger than the distance y between the two flat surfaces 26 and 27. If there were only one flat surface 26, the distance y would be measured from this flat surface 26 to the cylindrical surface 25 of the outer contour 24.
  • the pivot angle should expediently be smaller than the mentioned pivot angle ⁇ .
