Definitions

  • the present invention concerns a spinning or twisting spindle.
  • spindles of which are driven by a central driving unit, it is known, through the intervention of lbelts and/ or transmissions, to bring about a braking or stopping of each individual spindle.
  • the heretofore known brakes and stopping devices are so designed that the spindle may, together with the cop thereon, be braked and stopped as a unit, whereas the driving means which are coupled to the spindle during the operation thereof, may continue to rotate.
  • the whorl is disengaged from the spindle shank while simultaneously brake shoes engage the part to be braked and stop the same.
  • the braking of the yarn body or cop is effected manually after the spindle as an entirety has been disengaged from the driving means therefor.
  • This mass comprises the yarn body, viz. the bobbin or the sleeve with or without the yarns, ⁇ and furthermore, the spindle or -a considerable portion thereof.
  • an object of the present invention to provide a spinning or twisting spindle in which of all rotating parts, exclusively the yarn body is braked.
  • FIGURE l diagrammatically illustrates lin section :a spinning spindle with stationary spindle shank and ⁇ with a disengageable clutch adapted to engage the outside of the yarn body bob-bin;
  • FIGURE 2 is a cross-section through the spindle according to FIGURE 1 within the range of the disengageable clutch and along lI-II of FIG. l;
  • FIGURE 3 represents a longitudinal section through a spinning spindle with stationary spindle shank and with a disengageable clutch adapted to engage the yarn body bobbin from the inside;
  • FGURE 4 is a spinning spindle with driven spindle shank and with disengageable clutch.
  • the present invention is based on a spinning or twisting spindle in which the upper end of the spindle shank carries a freely rotatable supporting body for the bobbin to be placed thereon.
  • a spindle shank may rotate with the driving whorl or may be arranged stationarily.
  • the bobbin has its upper end resting ⁇ on the freely rotatable supporting body, whereas its lower end is placed upon the rotating whorl or parts connected thereto.
  • Such an arrangement is disclosed, for inst-ance, in German Patent No. 1,126,785.
  • spindle shank 1 passes with play through the bearing sleeve 2 and is hel-d by a ball cup 'body 3 of elastic material as, for instance, an ethyleneglycol -adipic acid'polyester in combination with naphthylene-l,S-diisocyanate (trademark Vulcollan).
  • a ball cup 'body 3 of elastic material as, for instance, an ethyleneglycol -adipic acid'polyester in combination with naphthylene-l,S-diisocyanate (trademark Vulcollan).
  • spindle shank l may be raised t-o a greater or less extent.
  • ⁇ spil-idle shank 1 carries a freely rotatable Cup-shaped supporting member 5.
  • This supporting member 5 is adapted to rotate together with the connecting pin 6 which latter extends through a bore 7 with arched wall surfaces and is by a head 3 prevented fro-m lifting off.
  • the connecting pin 6 which latter extends through a bore 7 with arched wall surfaces and is by a head 3 prevented fro-m lifting off.
  • Supporting body 5 is adapted freely to rotate and is also adapted, to a lirnited extent, to carry out tumbler movements so that the yarn body bobbin 4 can be axially mounted in such a way that it will engage the disengageable clutch at the ⁇ driving whorl, to the required extent.
  • the lower end of the yarn body bobbin may rest on the upper end face of a sleeve forming an upward extension of whorl 15
  • the disengageable clutch may consist of clutch shoes which, from the outside, engage the yarn body 'bobbin and are guided in the sleeve while having their outer ends resting against the inner surface of an axially displaceable conical sleeve freely rotatably journalled on the whorl sleeve.
  • the conical sleeve is axially displaced to such an extent that the clutch jaws may radially move outward-ly. This movement is effected automatically due to the centrifugal force, so that automatically with the axial displacement of the conical sleeve, there will be obtained a disengagement so that the yarn body bobbin will no longer be driven and will come to a standstill.
  • the clutch position may, for instance, be arrested by a spring, magnets, the weight of the conical sleeve -or the like, so that the displacement of the conical sleeve must overcome Ithese forces while on the other hand, the coupling operation will be effected automatically.
  • the yarn body bobbin 4 when -being mounted, the yarn body bobbin 4 surrounds, with a certain play, the upper end of bearing sleeve 2.
  • the inwardly extending fiange 11 of a conical sleeve 12 surrounds the ⁇ lower end of the yarn body bobbin 4.
  • the said conical sleeve 12 is by means of an antifriction bearing 13 freely rotatably journalled on an extension sleeve 14 of the driving whorl 15.
  • Sleeve 12 is displaceable axially upwardly against the thrust of a spring 1-6 which tends to press sleeve 17. downwardly as far as possible.
  • FIG. 1 shows a sleeve 12 in this position.
  • the upper end of the extension sleeve 14 of whorl 15 has connected thereto the inner ring 17 of the anti-friction bearing 13.
  • This inner-ring is firmly mounted upon the extension sleeve 14 of whorl 15 and forms, so-to-speak, a unit with said sleeve.
  • Distributed over the circumference of inner ring 17 are three passages 18 in which radially displaceable clutch jaws 19 are mounted.
  • the clutch jaws 19 are pressed radially inwardly against the lower end of the bobbin 4 which rests at its lower end u-pon the upper end face of extension sleeve 14.
  • the lower edge portion of the yarn body bobbin may likewise rest on the upper end face of a sleeve extension of the whorl, and a disengageable clutch may be provided which is composed of a plurality of two-arm tiltable levers journalled on the whorl extension sleeve. Said tiltable levers are arranged between the whorl extension sleeve and the spindle shank, and the upper clutch arms are adapted selectively to engage the yarn body bobbin from the inside for rotating said bobbin or to disen-gage said bobbin to interrupt the drive therefor. In this way, it is likewise necessary merely to stop the cop.
  • FIG. 3 An arrangement of the type just referred to is 'more specifically shown in FIG. 3.
  • the arrangement according to FIG. 3 likewise comprises a stationary spindle shank 25 which is connected to the spindle rail 23 by means of sleevess 21 similar to the arrangement of FIG. 1.
  • a nut 22 similar to Ithe arrangement of FIG. 1 and there is furthermore provided a supporting shoulder 24 on the spindle shank 25 so that the spindle shank 25 is firmly stationarily held.
  • each tiltable lever 30 has a leaf spring 32 on the outside thereof.
  • the lower lever arm of each of said levers has its inner surface in engagement with the outer surface of a ring 33 carried by radially directed arms 34 which extend through longitudinal slots 35 in a spindle shank 25.
  • These arms are carried by an adj-usting shank 36 which extends through the spindle shank 25 in axial direction thereof and is adjustable as to height.
  • the lower end of shank 25 is provided with a thread 39 threadedly engaged lby a threaded cap 37 which has an actuating or tilting lever 38. It will be appreciated that turning lever 38 in a horizontal plane with regard to FIG.
  • the center of gravity of the tiltable levers is located above the pivotal supporting points of said tiltable levers so that when said levers are rotating, the centrifugal ⁇ force will automatically press the upper clutch arms of the tiltable levers outwardly and thus will bring about a rotation of the yarn body bobbin. More specifically, the center of gravity of sai-d tiltable levers 30 is located above the tilting points of levers 30.
  • the arrangement according to the invention is by no means limited thereto.
  • the invention may also be realized by having the lower end of the yarn body bobbin placeable upon a sleeve freely rotatably mounted on a driven spindle part.
  • Such freely rotatable sleeve may widen at its lower end to form an open pot on which a further sleeve is axially displaceable, said last-mentioned sleeve being at the inside thereof equipped with a multi-pole magnet facing thereabove a multi-pole magnet which rotates with a driven spindle part.
  • the bobbin is freely rotatable on the rotating spindle part.
  • the bobbin is rotated by said spindle part by the magnet supported by the freely rotatable sleeve.
  • This magnet is rotated by the magnet rotated by the spindle part so that at the same time also that sleeve will rotate which is drivingly connected to the yarn body bobbin, and thus is likewise rotated.
  • that magnet which is carried by the sleeve broadening out in a pot-shaped manner may be displaced axially, this magnet can easily be axially moved by the magnet carried by the driven spindle part, and this axial movement may be such that the magnetic field will be interrupted.
  • the bobin is separated from the driven spindle part and can be braked independently therefrom.
  • the -disengageable clutch is formed by two oppositely located magnets one of which is movable away from the other. If the moved-away magnet is again moved toward the rotating magnet, it will again be carried around, i.e. rotated by the magnetic force so that also the sleeve carrying said last-mentioned magnet will be rotated and consequently, the bobbin on said lastmentioned sleeve.
  • FIG. 4 An arrangement of this type is shown in FIG. 4 according to which the upper end of spindle shank 44 has arranged thereon an anti-friction bearing 45 around which the cup-shaped supporting body 46 can rotate.
  • the supporting body 46 is at the same time able to carry out slight pendulum movements, as they have been referred to in connection with the description of FIG. 1.
  • the arrangement of FIG. 4 comprises a driven spindle shank 44 relative to which the supporting body 46 may be at a standstill.
  • the lower end of spindle shank 44 is in customary manner joumalled in a spindle housing generally designated 47 which in its turn is connected to the spindle rail 23.
  • the driving whorl 48 surrounds the outside of the spindle housing 47.
  • the upper end of whorl 48 is placed directly upon the conical section 49 of spindle shank 44 so as to rotate the latter.
  • a sleeve 50 with flange 51 is slipped over spindle shank 44 for rotation with shank 44.
  • flange 51 carries a multi-pole annular magnet 52 facing a multi-pole ring magnet 53.
  • Ring magnet S3 is carried by a flange 54 of a sleeve 55 which is axially displaceably arranged in pot 56.
  • Pot 56 forms a downwardly open wider section of sleeve 57 which by means of an antifricton bearing 58 is freely rotatably journalled on sleeve 50.
  • the latter is provided with a handling ring 59.
  • the yarn body bobbin 4 is freely rotatably journalled on the spindle shank.
  • Bobbin 4 is rotated by the driving whorl by means of a clutch engaging the yarn body bobbin either from the inside or from the outside.
  • the clutch is adapted by axial displacement of an actuating member to be engaged or disengaged and its engagement may be effected automatically by force of springs, or the like.
  • the invention therefore, realizes the object that the yarn body bobbin also may be braked and stopped without the necessity of having to brake other rotating parts of the spindle in order to stop the cop.
  • the power requirement for again starting or rotating the bobbin after the latter had been stopped is less than with heretofore known spindles because the bobbin or cop alone has to be put into motion.
  • the clutch may remain in its engaged or disengaged position for any desired length without other parts frictionally engaging each other, as is the case with heretofore known spindles.
  • a textile spindle having a spindle shank, bobbin supporting body means freely rotatably supported by said spindle shank and supporting said bobbin, whorl means coaxially surrounding said shank and adapted to be drivingly connected to driving means, clutch means operatively disposed between said whorl means and the lower portion of said bobbin and adapted to establish and interrupt driving connection of said whorl means, a member associated with said clutch means having a rst position wheerin said clutch means is effective to establish 'said driving connection and a second position wherein said clutch means is ineffective ⁇ to establish said driving connection, and means connected to said member for moving said member between its said rst and second positions, said means being selectively operable during continued rotation of said whorl means to permit said bobbin to be halted and removed from said bobbin supporting body means and replaced by a new bobbin and the said new bobbin set into motion.
  • said clutch elements comprise a plurality of two-arm levers tiltably supported by said extension means and each having a portion of one arm thereof located adjacent said bobbin, spring means acting on the other arm of each lever operatble to actuate the pertaining two-arm lever for selectively causing said portion of one arm thereof frictionally to engage a bobbin supported by said bobbin supporting body thereby drivingly to interconnect said whorl means and bobbin, said member associated with said clutch means comprising a mechanical actuator selectively moveable into engagement with said other arms of said levers to tilt the levers against the bias of said springs and disengage said portions of the said one arms thereof from said bobbin.
  • said bobbin supporting body means comprises a lower part at the lower portion of the bobbin having a dependent cup shaped portion
  • said clutch means comprising a first multipole magnet carried by said spindle shank to rotate therewith and located in said cup shaped portion near the top thereof and a second multipole magnet in the cup shaped portion beneath said first multipole magnet
