Definitions

  • the invention relates to a device for yarn carrier change in a textile machine, in particular a ring spinning, funnel spinning or ring twisting machine, in which a spindle pair on a turret is arranged symmetrically to the turret axis such that one spindle alternates with the other spindle of the pair from a spinning position in an unwinding or disposal position - and vice versa - is rotatable.
  • the spinning bobbins produced on ring spinning machines contain a thread quantity that is too small for most applications and must be rewound onto much larger packages.
  • the transfer of the finished spinning bobbins from the spinning stations to the unwinding stations was previously usually associated with labor-intensive handling of the spinning bobbins, starting with the doffing process on the spinning machine, transporting them to the winding unit, aligning the finished spinning bobbins and preparing them at special preparation stations Put on the unwinding spindle and finally the empty tubes are transported back to the spinning machine and put back on the spindle.
  • the invention is described below in connection with a ring spinning, in particular a ring spinning machine, in which spinning sleeves are used as the yarn carrier.
  • the invention is or the like with the same advantages also on ring twisting, funnel spinning machines. applicable.
  • the invention is also not subject to any application restrictions with regard to the formation of the yarn carrier.
  • cylindrical or conical sleeves or the mandrels themselves can be used as yarn carriers.
  • the invention has for its object to improve the generic device so that previously viewed as contradictory demands for small turret diameters and spinning spacing on the one hand and relatively large free spaces can be fulfilled together for a disability-free and simultaneous implementation of the spinning and unwinding operations.
  • the invention makes use of the knowledge that the space requirement of a spinning winding unit in the generic device is practically exclusively dependent on the largest diameter of the turret, while the span of the spindles and the spinning sleeves carried by them is relatively uncritical.
  • the spindles of a revolver which diverge upwards according to the invention follow a frustoconical path when the spindle is changed. This path can reach over the neighboring revolver unhindered and can even dip between its correspondingly diverging spindles. It is only important that the neighboring revolvers are rotated out of phase so that the spindles at the Dre hen can interlock tooth-like in the respective gap between the stationary spindles of the neighboring turret.
  • a compact design and simplified operating options for adjacent spinning positions or twisting positions can be achieved in that a turret is equipped with at least two pairs of spindles and is provided for operating at least two adjacent spinning positions, with two spindles lying next to one another at a pitch run in parallel.
  • the spindle change of two or more spinning / winding positions can be achieved by turning a single turret.
  • an alternative embodiment is characterized in that the turret carries two spindles and that the spindle axes form the generatrix of a cone open to the free spindle ends, the central axis of which is the turret axis.
  • the ring spinning machine can be retained in a conventional design if the spindle axes run vertically in the spinning position and the turret axis is inclined at an acute angle to the vertical plane.
  • the axis of the spindle in the unwinding position is inclined with respect to the horizontal plane depending on the angle of inclination between the two spindle axes between 0 and 50 °, preferably between 30 and 50 °.
  • each turret has partially circular recesses in the area of its circumferential sections between the spindle outlets, the radius of curvature of which is adapted to the distance to the adjacent turret axis.
  • a turret is created with a maximum diameter in the plane of the two spindle axes and a minimum diameter perpendicular to this connection plane.
  • each pair of spindles are assigned yarn release agents which are effective in the area between the spindles located in the spinning position and in the winding position.
  • FIGS. 1 and 2 A first exemplary embodiment of the device for changing the spinning sleeve in a ring spinning machine is shown purely schematically in FIGS. 1 and 2 with the functionally essential components.
  • the ring spinning machine itself can be of a known design.
  • a turret 1 is assigned to each spinning station of a ring spinning machine.
  • the turret 1 is rotatably mounted about a machine-fixed axis 11.
  • Each turret carries two spindles 2 and 3, the axes 12 and 13 of which are arranged inclined at the same acute angles to the turret axis 11 and diverge in the direction of the free spindle ends.
  • the axis 12 of the spindle 2 is - as usual in conventional spinning machines - in the vertical position, so that the ring bench (not shown in FIG. 1) can be lowered and raised vertically onto the spinning sleeve.
  • the opposite spindle 3 is in the unwinding position and in the illustrated embodiment is inclined by approximately 45 ° with respect to the spindle axis 12. 1 and 2, the spindles are each occupied with a finished spinning cop 4 and an empty tube 5 in order to illustrate the paths and the space required, especially when turning a revolver and the full and empty spinning tubes held thereon. All spindles and spinning sleeves are shown cylindrical to simplify the drawing.
  • concavely curved recesses 7 are formed whose radius of curvature R is adapted to the distance between the turret axes of rotation 11, 11 'between adjacent turrets 1, 1'.
  • the recesses are arranged on the longitudinal sections of the circumference located between the spindle outlets.
  • the circumferential regions 9, 9 ', which are adjacent to the spindle outlets, are preferably convexly curved under the same radius R.
  • the shape of the turret in particular the design of the turret top at the exits of the spindles and its underside with the bearing opening 10 coaxial with the turret axis 11, is not critical and can be adapted to the conditions on the machine frame.
  • Fig. 2 shows a perspective top view of the movement path and relative position of adjacent spindles and cops when turning a revolver.
  • the turret 1 adjacent to the turret 1 ' is shown in the position rotated by about 60 ° from the operating position in the direction of arrow A. This is the position in which the finished cops 4 and 4 'come closest.
  • the axis 12 'as well as the axis 131 when rotating the turret 1' forms the generatrix of a truncated cone, the apex 14 of which lies below the turret on the turret axis of rotation 11.
  • a slightly wider truncated cone will formed by the outer surface of the finished cop 4t.
  • the cop 41 passes over the V-shaped region between the cop 4 and the empty sleeve 5 located above the adjacent revolver 1, without colliding with the lateral surfaces thereof.
  • the cone cross section can be reduced if necessary.
  • the inclination of the spindle axes enables the current minimum ring spinning pitch t of, for example, 75 mm to be maintained with an optimally quick change of the spinning and winding spindle.
  • the V-shaped space between the spindles 2 and 3 assigned to a turret 1 offers sufficient free space, especially in the head region, for unimpeded execution of the spinning and winding operations.
  • Proven spindle bearings can be used. Tangential belt drives or individual drives can be used to drive the spindles in the spinning action.
  • the turning of the turret 1, 1 ' is preferably carried out by a central shaft, not shown in the drawing, with all even and odd turrets alternately rotated about their associated axes of rotation in the same direction by 180 °. Each time a turret is turned, the turrets that are adjacent on both sides remain in their spinning or winding positions, so that the (minimal) spindle pitch can be maintained.
  • the turrets shown in Figures 3 and 4 each serve two spinning bobbins. Only the revolvers with their central bearing bores 10 and the receiving bores 30 concentric with the spindle axes are shown for the spindles and spindle bearings.
  • FIGS. 3A and 3B show the simplest design of a revolver 21, in which four spindle axes 22, 23, 24, 25 are in parallel lel and are arranged concentrically about a turret axis of rotation 26.
  • the radius of curvature R is adapted to the distance to adjacent turret axes 26 'adjacent turret 21'.
  • the receiving bores 30 have three cylinder sections widened in steps toward the spindle outlet (FIG. 3B).
  • turret 21, 21 ' are shown with their spindle mounting holes 30 in the operating position, in which the spindles are in the spinning or unwinding positions.
  • the axes 22 and 23 of spindles adjacent in the machine longitudinal direction (arrows B) are at a distance corresponding to the spindle pitch t.
  • the adjacent axes 23 and 22 ' have the same distance t from two adjacent turrets 21 and 21'.
  • the spindles that belong together are not the spindles with the spindle axes 22 and 25 lying next to one another in the transverse direction in accordance with the section BB, but rather are arranged crosswise, that is to say diametrically to the turret axis 26 Spindle pairs in association with the spindle axes 22 and 24 or 23 and 25. These each change their position at one Spindle rotation through 180 °.
  • the assignment of the winding units to the spinning units is of no importance for the functional features of a ring spinning machine.
  • the embodiment of the turret 41 shown in FIG. 4 differs from the embodiment 21 according to FIG. 3 in that the spindle axes 42-45 are arranged inclined at an angle symmetrically to a plane 50.
  • the turret axis 46 lies in the plane of symmetry 50.
  • Two spindle axes 42 and 45 or 43 and 44 lie in a vertical plane (e.g. cutting plane B-B) but belong to different pairs of spindles, i.e. operate adjacent spinning positions and winding positions.
  • FIGS. 38 and 48 shows, with the inclined arrangement of the spindle axes 42 and 45, because of the spreading towards the free spindle ends, there is considerably more space available for carrying out the spinning and unwinding operations with otherwise the same turret volume and turret diameter.
  • the turrets can therefore be built even more compactly and the spindle pitches t shown here as being the same can be made smaller.
  • the top design of the revolver 41 is also not critical.
  • Fig. 48 a roof-shaped top profile 51 is shown, which keeps the material requirements and the manufacturing costs low with favorable operating properties.
  • the spindle axes 42, 45 penetrate the flat portions of the surface profile 51 assigned to them at right angles, which is advantageous for carrying out the spinning operation as well as the unwinding operation.
  • Revolvers of the type shown in FIGS. 3 and 4 can also be assigned more than two pairs of spindles in association with more than two spinning, twisting or winding positions. This reduces the number of change operations per unit of time and thus the operational and structural effort; but increases the (mostly uncritical) space requirement in the cross machine direction, i.e. perpendicular to the spindle pitch t.
  • Fig. 5 the device for changing the spinning sleeve together with the spindle-near components of a spinning station is shown schematically.
  • the turret has the design of the turret 1 from FIG. 1. It is rotatably mounted on the spindle bench 16, which is only shown schematically, via a bearing 15.
  • the turret is shown in FIG. 5 immediately after changing the spinning sleeve and before re-spinning on the spinning sleeve 5 which is in the spinning position.
  • the ring bank 60 which is also only indicated schematically, can be raised upward beyond the free end of the spindle or spinning sleeve 5 and, after the turret 1 has been rotated into the position shown in FIG.
  • the thread 61 runs from the top turn on the spun spinning tube 4 that is now in the winding position through a schematically illustrated pressing and cutting device 62, from there through the spinning ring 63 and past the head region of the tube 5 at the top in the swarm tail or spinning triangle.
  • the pressing and cutting device 62 is preferably pivotally attached to the ring bench 60. In the cutting position shown in FIG. 5, it lies in the V-shaped space between the two spinning sleeves 4 and 5, which are held on the turret 1.
  • the thread leading to the bobbin 4 to be unwound is separated from the thread end to be spun at the latest when the spindle carrying the empty sleeve 5 starts up.
  • double thread formation is reliably avoided.
