Definitions

  • a passage system extends along said direction, communicates with the discharge outlets, and communicates with the ambient [30] Foreign Application prwmy Data atmosphere over at least a major portion of its length.
  • the invention relates to open-end spinning machines.
  • a flow of air is a necessary condition for many types of spinning machines, particularly openend spinning machines.
  • the air flow feeds separated fibers to the spinning chamber and deposits such fibers on the collecting surface of the spinning chamber.
  • the fibers are converted into yarn, by twisting or the like.
  • the air flow which is necessary, for example, for feeding the fibers to be spun can be produced by a fan provided in or associated with the spinning chamber, the fan rotating together with the rotating part of the spinning chamber or merely being in association therewith.
  • the air flow can be generated within the spinning chamber itself by the action of centrifugal force associated with moving components.
  • the air stream may be generated at a more or less remote location by a central fan which, for example, might supply a flow of air for a number of spinning units.
  • Overhead withdrawal conduit systems heretofore employed utilize suction to withdraw streams of air from individual spinning units, and then to convey such withdrawn air over considerable distances to a central collecting chamber.
  • the suction required for such withdrawal and conveying is substantial, so that a central pressure arrangement must be provided which serves one or more such conduit systems and creates therein the suction necessary for making the conduit systems effective.
  • the great problem with such systems, which directly affects the quality of the yarn being produced, is the existence of uneven underpressure and flow conditions throughout the withdrawal conduit system. Spinning units located near the central source of suction will be influenced by a very strong underpressure, whereas spinning units located at points along the conduit system which are far from the suction source will be served by a much reduced suction action.
  • the novel textile installation includes a plurality of spinning units arranged in substantially side-by-side relationship along a given direction.
  • Each such unit has a discharge outlet for discharge of air during operation of the unit.
  • a passage system extends along the direction in which the spinning units are arranged and communicates with the respective discharge outlets, as well as with the ambient atmosphere, over at least a major portion of its length. In this way, the air flow discharged from each of the discharge outlets will travel through such passage system to the ambient atmosphere along substantially identical flow paths. As a result, the air-flow and pressure conditions within the plurality of spinning units will be largely identical.
  • FIG. 1 is a sectional view through a textile machine including one embodiment of the present invention
  • FIG. 2 is a sectional view through another textile machine including another embodiment of the present invention.
  • FIG. 1 a spinning machine is illustrated in sectional view.
  • An internal space 1 is provided in the central, interior part of the spinning machine, and constitutes in this embodiment a part of the novel withdrawal system.
  • the internal space 1 is provided in form of an elongated passage extending down the length of the spinning machine and defined by side walls 2, bottom 3 and upper housing portion 4.
  • each side of passage 1 Arranged along each side of passage 1 is a row of spinning units 5. Associated with each unit 5 is an air discharge outlet 6, which communicates with passage 1 and, during operation of the respective unit, discharges air thereinto.
  • the passage 1 is closed at its upper portion by an upper housing portion 4 of the machine housing.
  • Vents 7, in this embodiment are provided in housing portion 4, and designed to discharge air streams to the atmosphere in substantially upwards direction.
  • the upper housing portion 4 includes two walls, each oriented at an angle to the horizontal. Such orientation facilitates discharge of air in upwards direction.
  • the vents 7 themselves are provided with outlets of such design as to cause air to be discharged from the machine in upwards direction into the ambient atmosphere.
  • dust traps 8 are provided behind i.e. upstream of-vents 7 and may constitute filter inserts, or any other suitable arrangement, for separating small particles and impurities ll from the air 9 fed from spinning units 5. It is an advantageous expedient, with such construction, to permit these impurities 11 to fall to the bottom 'of passage l and be collected in dismountable collection channels.
  • Such channels need not be dismountable, and instead of periodically removing them for cleaning purposes, they may be continuously cleaned in an automatic operation, if desired.
  • Such continuous and automatic cleaning could proceed, for example, either pneumatically or mechanically, or possibly even electrostatically.
  • FIG. 2 shows another spinning machine including an embodiment of the invention.
  • the passage arrangement is provided in form of a central, interior passage 1 extending within and along the length of the spinning machine.
  • vents 7 are provided on both the side walls 2 of the housing, as well as on the walls of the upper housing portion 4.
  • Suitable impurities-removing means are provided, here in the form of simple filters 8 so arranged that air leaving through vents 7 must first pass therethrough.
  • the filter means employed will depend on the quality of filtration desired, and in particular on the character and amount of impurities present in the air flow. Accordingly, while for the sake of simplicity of illustration only simple filter means are shown, the filtering may be accomplished through the use of more complicated, and even very sophisticated filtering techniques.
  • FIG. 3 shows a still further installation according to the invention.
  • a more involved dust-trap arrangement comprising a plurality of dust-traps 8.
  • the dust traps 8- which may be of the kinds mentioned previouslyprovide guidance for the air 9, as shown.
  • FIG. 4 is a representational view showing the general appearance of a textile machine incorporating one of the embodiments of FIGS. 1-3. Clearly, when embodiments different from those of the drawing are constructed, the overall appearance of the machine may be quite different. It will be appreciated, nevertheless, that the machine depicted in FIG. 4 is simple, compact and convenient to install.
  • the method according to the invention is performed as follows:
  • Fibrous material is separated in the fiber-separating components of the textile installation of the invention, and sucked into the spinning chamber of the installation, under the influence of underpressure, the underpressure being maintained by the centrifugal action of the rotating spinning chamber itself, or being produced by an auxiliary source.
  • the fibers are converted in the spinning chamber into yarn, while simultaneously air 9 is withdrawn from the respective spinning units 5,
  • vents 7 blows upon the upper part of the machine and thereby removes impurities accumulated thereon, largely eliminating the heretofore so troublesome problems of sedimentation.
  • the invention has been concretely illustrated in a particular type of spinning installation.
  • the passage means serving for withdrawal of discharged air is provided in the form of a central, interior space within the textile machine itself. It should be appreciated, however, that such disposition is by no means absolutely necessary.
  • the passage arrangement may be different, depending on the particular application, and may be located otherwise with respect to the individual spinning units. Obviously, the spinning units need not be provided in two rows, but may be provided in a single row, or in more than two rows, or in still another arrangement. The advantages of the invention will still be obtained even if the passage means is in quite different form from that shown, and arranged quite differently, providing that the air-flow paths from each spinning unit, or the like, are substantially identical.
  • vent means are arranged to guide air from said passage means substantially in an upwards direction.
  • said passage means including a plurality of wall portions including at least one upper wall portion oriented at an angle to the horizontal.
  • said wall portions include side wall portions and ceiling portions, and wherein said at least one wall portion is a side wall portion.
