Definitions

  • This invention relates to improvements in text1le machinery and more particularly to imemployment of small quantities of air.
  • ferences may, according to the design of the particular spinning frame, assume substantial proportions.
  • the ciprocating movement of the nozzles is, to allow for these differences, so selected as to differ from the cycle of the reciprocating movement of the yarn guide eyelets, it is possible, without detriment to the eiiectiveness of the nozzles, to arrange for the nozzle apertures, and consequently the necessary cuantity of air handled by the pneumatic installation, to be kept extremely small.

  • a spinning machine with a two-unit draw frame is shown.
  • Each draw frame unit comprises four nip rollers per thread of yarn filament, namely, the fluted cycle of the refluted intake rollers I of the various drawing frames are mounted on a driven shaft 5 and, correspondingly, the fluted delivery rollers 3 are mounted on another driven shaft 6.
  • the roving paid out by the is drawn into the draw frames take rollers 3; the roving is there drawn and the yarn so obtained is finally taken up by the driven spindles H.
  • the roving is in this process led, before reaching the draw frames, through yarn uide eyelets 9 and the finished yarn is led, before reaching the spindles, through yarn guide lappets it.
  • the yarn guide eyelets 9 are moved to and fro, by means of the yarn feed motion, parallel to the axes of the draw frame rollers l to 4. To this end the yarn guide eyelets 9 are arranged on a machine cross-member l2 displaceable along its longitudinal axis, which cross-member may for instance be moved reciprocatingly by a crank pin it through a rod 33.
  • the crank pin M of the yarn feed motion may be driven by a shaft N5 of the spinning frame through a suitable intermediate gear shown in Fig. 1 as an ordinary intermediate gearwheel [5.
  • the reciprocating mofrom theshaft I 6 placed radially.
  • nozzles H of a pneumatic installation are arranged between the fluted delivery rollers 3 of the draw frames and the yarn guide lappets l8, nozzles H of a pneumatic installation are arranged. These nozzles may consist of simple and preferably slot-shaped apertures in a collecting duct 18, which is connected by an articulated member 25 to the fan 20.
  • the pneumatic installation is so designed that the fan 2s sucks in air from the nozzles H in the direction shown by the arrows in the drawing. Dust, flufi, broken yarn-ends and the like are drawn in by the nozzles l1 and the particles so removed are collected inthe separator 19.
  • a further machine cross-member is provided the sole purpose of which is to cause the reciprocating motion of the nozzles ll.
  • This machine cross-member may, as already indicated in Fig. 1, be the collecting duct is itself on which the nozzles 11 are mounted.
  • the collecting duct 1'8 is for this purpose so designed as to be displaceable in its longitudinal direction, and is moved to and fro through a system of rods 2
  • Said crank pin 23 is driven through an intermediate gearwheel 24 or through an intermediate gearing, in such a manner that the two crank pins l4 and 23 respectively rotate'at the same speed in the same direction.
  • the collecting duct IS with the nozzles I? is controlled and moved to and fro out of synchronism with the yarn guide eyelets 9.
  • the cycle of motion of said collecting duct 58 with the nozzles 11 may diifer simply in the fact that the amplitude of the reciprocating movement of the nozzles I1 is smaller than that of the reciprocating movement of the yarn guide eyelets 9.
  • the position shownby a dotted line of the yarn filament 8', the nozzles l1 and the collecting duct 13', the rod system 22 and the crank pin 23 illustrates these circumstances.
  • the necessary amplitude .of movement of the nozzles ll is smaller: than that of the yarn guide eyelets 9, because the vyarn filaments, on account of the rigidly mounted yarn guide lappet 10, are displaced less far on the delivery rollers -3 than on the intake rollers l of the draw frame.
  • a device by means of whichthe amplitude of the reciprocating move mentor the nozzles is adjustable in relation to that of the reciprocating movement of the yarn guide eyelets may, in its simplest form, consist in an arrangement whereby the pivot pin by means of which the system of rods 22 is-articulated to the crank pin 23 can be disindicated guide eyelets 9. the reciprocating movement of the yarn guide in the drawing by the slot 29 radially provided in the crank pin 23.
  • the yarn leaving the drawn frame lags behind the reciprocating movement.
  • the nozzles H in such case are controlled to follow a cycle lagging behind that of the yarn
  • the distance-time curve of eyelets is sinusoidal
  • suitable means are provided by which the phase position of the reciprocating movement of the nozzles is adjustable in relation to that of the reciprocating movement of the yarn guide eyelets.
  • such an adjustment of the phase may be effected by temporarily removing the intermediate gearwheel 24, off-setting the crank pin M with the shaft It in relation to the crank pin 23 by the desired phase angle, and then replacing the intermediate gearwheel 24.
  • the cycle of the reciprocating movement of the nozzles coincides with that of the yarn guide eyelets only as regards the "periodic duration of the reciprocating motion, whilst within the period the nozzles may be controlled to a cycle the time curve of which deviates completely from that of the yarn guide eyelets.
  • the distance-time curve of the reciprocating movement of the yarn guide eyelets 9 is a zlg-zag curve consisting of straight lines
  • the nozzles may be controlled in accordance with a cycle derived from a sine curve distorted by uneven harmonics, the zero points (origins) of the distorted sine curve being out of synchronism with the zero points of the zigzag curve in that they lag behind the latter, and the amplitude of the distorted sine curve being less than that of the zig-zag curve.
  • the length of the nozzle slot is made somewhat greater than would be necessary if the nozzles were exactly to follow the movements in question.
  • the machine cross-members provided for the yarn guide eyelets and nozzles are, as shown in Figure 1, simultaneously driven from a common shaft I 6, suitable mechanism being provided to permit separate control of such members. In stead of mechanical coupling of this type, electrical coupling is also possible.
  • a particularly convenient structural arrangement is achieved when the machine cross-member provided for actuating the nozzles is itself moved backwards and forwards and the portions of the pneumatic equipment carrying the nozzles are entrained by the machine cross-member in its reciprocating movement.
  • this construction it is possible by simple means so to effect the connection between the nozzles and the machine cross-member which moves same backwards and forwards that the distance between the nozzles and the draw fram is easily adjustable and further that the nozzles can be swung out of their normal operating position, which is near to the delivery nip rollers.
  • Such an arrangement substantially facilitates not only the overhaul, and replacement of the nozzles, but also, when longstapled material is being spun, the knotting of broken ends between the draw frame and the spindle.
  • Typical embodiments in this connection are shown diagrammatically in Figs. 2 to 5 of the drawing.
  • Figures 2 and 3 illustrate a modification of the invention.
  • the yarn guide eyelet 9 with its bracket 27, the machine cross-member l2 and the yarn filament it are omitted to obviate confusion.

  • the yarn eyelets 9 (Fig. 4) which move the yarn 8 to and fro in the axial direction of the fluted rollers I and 3 are mounted on brackets 21 which are secured direct to the machine cross-member 12.
  • the machine crossmember 60 provided for the actuation of the nozzles 6 I is fitted directly below the cross-member i2, an arrangement which may prove advantageous for structural reasons in the case of two-unit draw frames.
  • the two machine cross-members l2 and 60 are reciprocatingly moved, in Fig. 4, by
