Definitions

  • the present invention relates to a spindle, especially tWo-for-one twisting spindle.
  • a spindle especially tWo-for-one twisting spindle.
  • One of the main advantages of two-for-one twisting spindles is seen in the size of the bobbins and the length of the thread which, without work stoppage for exchanging the bobbin, can be twisted so that accordingly, the number of the knots in the thread will as a rule be less than is the case with ordinary spinning or twisting spindles.
  • FIGURE 1 illustrates a longitudinal section through a two-for-one twisting spindle with a thread storage disc loosely mounted on the driving means for said spindle;
  • FIGURE 2 illustrates the dot-dash-encircled pbrtion of FIGURE 1 but on a larger scale than the latter;
  • FIGURE 3 represents a section along the line IIIIII of FIGURE 2;
  • FIGURE 4 is a section similar to that of FIGURE 2 but an image thereof, and with the thread storage disc elevated over the position it occupies in FIGURE 2.
  • the present invention is based on a spindle, especially a two-for-one twisting spindle, in which the thread guiding tube together with the bobbin-receiving sleeve is journalled in the hub of the overflow turntable and, by
  • the spindle according to the present invention is characterized primarily in that the thread storage disc and the overflow turntable as well as those parts arranged thereabove and connected thereto are together loosely mounted on and are together detachable from the driving means for the spindle.
  • the driving means, on one hand, and those spindle parts which carry out the spinning and twisting operation proper, on the other hand are completely separated from each other along a substantially horizontal plane and are adapted to cooperate with each other by loosely mounting those two component parts or units one above the other.
  • the rotation of the thread storage disc and the parts arranged above the same and connected thereto is effected merely by mounting the said component parts or units one above the other.
  • the two component parts or units can be completely separated from each other by lifting off one of said units, it is possible, Without a threading instrument, to pass the thread radially outwardly from the thread storage disc.
  • the lifted off unit will thus be accessible from all sides and can be brought into any de sired position which will facilitate the threading of the thread and the exchanging of bobbins or other parts, especially when the lifted off unit is completely removed from the machine and is prepared outside the machine.
  • the two-forone twisting spindle illustrated therein comprises a thread storage disc 1 including an overflow turntable 2 connected thereto.
  • the thread storage disc 1 is in customary manner provided with a central recess 3 from which threadguiding grooves 4 extend radially outwardly.
  • These thread-guiding grooves 4 lead into a slit 5 (FIG. 3) so that it is possible to insert thread 17 into the thread stor age disc 1 from below into one of the grooves 4.
  • the edges of slit 5 are rounded and, if desired (as indicated in FIGS. 2 and 3), may be reinforced by a wear-resistant material such as asbestos with synthetic resin.
  • the central portion of the overflow turntable 2 is provided with an axially upwardly extending hub 6 within which there are provided anti-friction bearings 7 and '8 which support a thread-guiding tube 9.
  • the said tube 9 carries the bobbin mounting head 10 which receives the bobbin sleeve 11 and to which is connected a conical hub sleeve 12 for a protective basket generally designated with the reference numeral 13.
  • ⁇ Below bearing 7 and mounted on the thread-guiding tube 9 is a magnet 15 which may be designed as a multipolar permanent magnet and, if desired, may consist of a plurality of individual magnets composed to a ring magnet.
  • a bobbin 16 Received by and mounted on said bobbin sleeve 11 is a bobbin 16 from which the thread 17 is twisted off. Thread 17 when leaving bobbin 16, passes through thread-guiding eyelet 14 and then moves vertically downwardly through tube 9 and after leaving the same passes radially outwardly through a groove 4 provided in the thread storage disc 1. From said groove 4 the thread passes below the overflow turntable 2 and finally upwardly outside the protective basket 13.
  • the protective basket 13 is provided with a thread balloon confining can (not shown in the drawing).
  • the above-described parts form a closed unit.
  • the thread storage disc 1 with overflow turntable 2 is by means of bearings 7 and 8 freely rotatable about the thread-guiding tube 9, whereas the remaining parts fixedly connected to the thread-guiding tube 9 normally are at a standstill, with the exception of the freely rotatable threadguiding eyelet 14.
  • the said standstill is assured by arranging at least one countermagnet 18 opposite and in spaced relationship to magnet 15.
  • This countermagnet 18, which may be of the same type as magnet 15, is stationarily arranged centrally within the driving means for the storage disc.
  • the said magnet 15, in cooperation with magnet 18, will be able to assure that the thread storage disc with the ovenflow turntable and those par-ts which are located above and connected to the overflow turntable, will, during rotation of the thread-guiding disc, rest under the necessary pressure on the driving means for the turntable so as to prevent a tilting of the turntable or storage disc.
  • Cooperation of magnets and 18 also will assure the standstill of the thread-guiding tube and the sleeve with bobbin and protective basket, all carried by said threadguiding tube.
  • countermagnet 18 is arranged within the driving means for the spindle whichcomprises a driving whorl 19 the upper edge of which is provided with a radially outwardly extending flange 20 engaging surface 21 of thread storage disc 1 and supporting the latter.
  • Both parts, flange 2t) and disc 1 are coaxially arranged with regard to each other by means of the conical surface 22 of disc 1 and the correspondingly shaped conical surface 20a of flange 20, said two conical surfaces engaging each other. In this way, a large seat for the thread storage disc will be obtained on the driving means, and its central position with regard to said driving means will be assured.
  • the driving whorl 19 is rotatable about a stationary shank the upper end of which carries the said countermagnet 18. In this way, so to speak, in the interior, for instance of a two-for-one twisting spindle, there is formed a dead divided shank one section of which is located in the driving device, whereas the other section is located in the upper portion of the spindle and formed by said thread-guiding tube 9.
  • Axially displaceably arranged within the interior of tube 25 is a hollow shank 31 provided with an outer thread 32 which latter meshes with an inner thread 33 in tube 25.
  • the lower end of shank 31 is by means of thread 3-2 guided in tube 25, whereas the upper end of shank 31 is guided by a guiding surface 34 of hollow shank 31. It is above said guiding surface 34 that the countermagnet 1-8 is arranged.
  • the said magnets 15 and 18 may also be used for individually braking and stopping the storage disc of the spindle.
  • the countermagnet 18 may be arranged so as to be adjustable as to height.
  • Countermagnet 18 may in working operation of the spindle be located with play below the storage disc and may be provided with a friction surface facing a corresponding surface of disc 1. In this way, it will be necessary to lift countermagnet 1 8 by a slight distance only in order to bring about a braking and stoppage of disc 1. Furthermore, a high braking eifect will be assured. This braking effect may furthermore be improved by designing the disc 1 engaging portion of magnet 18 in the form of a radially extending flange facing the central recess 3.
  • Countermagnet 18 is provided with a radially extending flange 36.
  • This flange may form an integral part of countermagnet 18 and may be a magnet itself but if desired, it may represent a flange extending on the outside around the magnet.
  • flange 36 is so arranged that it is located outside the recess 3 closely below the surface 37 of the thread storing disc 1.
  • FIG. 2 clearly shows the relative relationship of flange 20 of the driving whorl 19 with regard to the thread storing disc 1 and also shows the relative relationship between flange 36 of magnet 18 and thread storing disc 1. Inasmuch as surfaces 21 and 22 of the thread storage disc 1 rest on flange 20 of whorl 19, it will be appreciated that when the spindle is in operation, the thread storage disc 1 is rotated by the driving whorl 19.
  • the thread storage disc 1 is loosely placed upon flange 20 of whorl 19. In this position as well as in the lifted braking position, the concentric location of the thread storage disc 1 with regard to its axis of rotation will be assured, viz. on one hand by the cooperation of the conical centering surfaces along the outer margin of the whorl flange 20 and on the thread storage disc 1, and on the other hand by the cooperation of the conical centering surfaces on flange 36 of magnet 18 with the thread storage disc 1. It will be evident that if desired, the centering of the parts may also be effected in any other known ways.
  • the spindle according to the present invention may, of course, be equipped with a broken thread end detector of any standard design, and this detector may be arranged.
  • each spindle is provided with an adjusting device which is actuated in common with the other adjusting devices.
  • the present invention has numerous advantages over heretofore known spindles of the type involved.
  • the present invention brings about a compact structure inasmuch as in contrast to heretofore known two-for-one twisting spindles with magnets, all magnets are coaxially arranged. While the magnets assure that the thread disc and the overflow turntable will be firmly pressed against the driving device, the said magnets nevertheless permit a lifting off and putting upon each other of the thread storage disc with the spindle parts connected thereto and located thereabove, while there exists no necessity of having to loosen mechanical parts such as screws or the like.
  • the present invention is, by no means limited to the particular construction shown in the drawing but also comprises any modifications within the scope of the appended claims.
  • the particular embodiment shown represents a two-for-one twisting spindle
  • the present invention may also be realized in connection with other spindles. It is merely necessary that the upper part which. carries the spindle sleeve is loosely seated on the driving device so as to be able at any desired time to be separated therefrom in the manner described above.
  • magnets and countenmagnets in coaxial arrangement are employed in order to assure the connection between the upper and lower spindle unit.
  • Preferred spindle types are twisting spindles and rubberapplying spindles.
  • magnet and countermagnet employed hereinbefore do not restrict the invention to the employment of permanent magnets but that instead, also multipolar magnets including electromagnets maybe employed, for instance also a two-polar magnet cooperating with a countermagnet consisting merely of an iron plate or the like closing the magnetic force field.
