Definitions

  • ABSTRACT Apparatus for the continuous spinning of textile fibers by the open end spinning method, particularly by means of a spinning chamber operating under pressure.
  • the separate spinning units of the apparatus are driven by a common drive from which they are separately disengageable.
  • the spinning chamber of each spinning unit is mounted in a stationary body on the machine frame; the separating and feeding mechanisms of each spinning unit are mounted in a body which is generally movable away from the spinning chamber, whereby to improve the ease with which the spinning units may be attended and maintained.
  • the present invention relates to a machine for the continuous spinning of textile fibers by the open end spinning method particularly by means of a spinning chamber operating under pressure, the separate spinning units in the machine being driven by a common drive from which they are separately disengageable.
  • the separate elements and working units of these machines are arranged side by side on one or both sides of the machine.
  • the oldest known machine of this type drives the spinning chambers, the separating mechanism and the feeding mechanism from continuous shafts extending along the whole machine.
  • the drive for both the spinning chambers and the separating mechanisms is by means of belts which pass along the whole length of the machine.
  • Machines of this type encounter difficulties, however, when the belt is operated in a horizontal plane. This imposes a considerable radial load upon the bearings of the driven elements.
  • the drive is tangential, in which minimum contact of the pulley occurs, particularly at the beginning of the branch of a belt.
  • the body in which the spinning chamber is mounted together with its bearing is swingable; this presents adverse conditions for the removal of heat which is generated by the rotary motion of the spinning chamber, and does not provide optimum stability for a long operating life of the high-speed bearing of the spinning chamber.
  • the present invention has among its objects the provision of apparatus which is at least substantially free of the above pointed out disadvantages of prior apparatus of this type.
  • the separate mechanisms of the spinning units are situated in two bodies, one of which is stationary.
  • FIG. I is a fragmentary, somewhat schematic view in front elevation of a first embodiment of apparatus in accordance with the present invention.
  • FIG. 2 is a view in vertical transverse section through the apparatus, certain of the parts being shown in elevation, the section being taken generally along the line II-Il of FIG. 1;
  • FIG. 3 is a detailed view of a portion of FIG. 2 on a somewhat enlarged scale, the figure particularly showing the drive of the spinning chambers;
  • FIG. 4 is a fragmentary, somewhat schematic view in side elevation of a portion of the driving mechanism for units at the right-hand side of the apparatus (FIG. 3), the drive for the right-hand two units being shown disengaged;
  • FIG. 4a is a fragmentary, somewhat schematic view in side elevation of a portion of the driving mechanism for units at the left-hand side of the apparatus (FIG. 3), the drive for the units being shown engaged;
  • FIG. 5 is a detailed view of the apparatus as it is shown in FIG. 2, the view showing a first embodiment of drive of the separating mechanism of the machine;
  • FIG. 6 is a detailed view of FIG. 2, the view showing the drive of the unit for feeding fibrous material into the spinning units of the machine;
  • FIG. 7 is a detailed view similar to FIG. 5 but showing a second embodiment of drive of the separating mechanism of the machine according to the present invention.
  • the machine of the present invention consists of a plurality of spinning units of similar construction, such units being mounted on the machine in side by side relationship on one or both sides of the machine. Since such spinning units are similar and the drives therefore as well as other portions thereof are the same, a description of one such spinning unit and its apertinent parts will suffice.
  • Such packages or bobbins are supported upon swingably mounted levers or frames 19, the bobbins being supported upon and driven by driven drums in the form of a continuous shaft 17.
  • Traverse mechanism (not shown) is provided in the vicinity of the drum I7 to relay the yarn across the bobbins in a cross-wound fashion as shown.
  • a main drive shaft 3, which is positioned horizontally and extends longitudinally throughout the length of the machine is rotatably mounted in the upper part of the machine frame.
  • a plurality of driving discs 4 are mounted upon the shaft 3 at regular intervals, in the embodiment shown there being one such disc 4 for each set of two oppositely mounted spinning units 9, 11. It is to be understood, however, that within the scope of the invention, each driving disc 4 may drive more than two units.
  • Each driving disc 4 is in operative contact with its respective driving belt 5, which is guided over guiding rollers 6 mounted on fixed axes and over an adjustable tensioning roller 7, as well as over the pulleys 8 of the spinning chambers 9 which are mounted stationarily In the bodies 10 on the respective machine frames 1.
  • the belt 5 for driving two opposed spinning units travels as follows: Starting at the point S in FIG. 3, the belt 5 travels in contact with the disc 4 for 180 after which it leaves in a vertical run and is twisted to run about pulley 8 of the right-hand spinning unit or the belt disengaging pulley 24, to be described. The belt then rises in a vertical run offset and free from contact with the disc 4 to the right-hand guide roller 6, being turned 90 in such travel. The belt then travels approximately about such guide roller 6, downwardly beneath the adjustable tensioning roller 7, up and partially about the lefthand guide roller 6 and then downwardly and about the drive pulley 8 of the left-hand spinning unit (FIG. 3). As the belt travels downwardly from the lefthand guide roller 6 to the driving roller 8 it is turned 90, the belt being restored to the plane of the periphery of the driving disc 4 as it rises from the pulley 8 to engage to disc 4 at the point S.

  • Each of the parts 11 of the spinning units 12 has a control member 27 in the form of a segment connected thereto, the upper surface of the segment 27 having a cam surface upon which the roller 26 rests.
  • the configuration of such cam surface is such that cause the roller 26 to descend under the action of the spring 28 when the parts 11 are in the closed position shown at the left in FIG. 3, and to cause the rollers 26 to be raised and thus the arms 22 to be rotated into the position shown in FIG. 4 upon the swinging outwardly of part 11 of the spinning unit in the manner shown in FIG. 3.

  • the intermediate roller 33 pulls away from the disc 30, and so the drive train between the shaft 20 and the separating cylinder 31 is broken.
  • Such feeding mechanism includes a feeding roller 45 mounted within the part 11. The remainder of the parts are disposed outwardly of the end wall on the part 11.
  • a continuous drive shaft 21 extends along each side of the apparatus as shown.
