Definitions

  • means shown as hand operated, for raising the bobbin from the drum, and means for 58 ⁇ Field 57/58 89 58 78 80 129 adjustably retaining the frame and bobbin in elevated position, 5 preferably with the surface of the bobbin spaced only a small distance above the peripheral surface of the drum.
  • Means, here shown as foot operated, is provided for releasing the [56] Reierences cued frame, when desired, whereby it is lowered so that the bobbin n- STATES PATENTS again rest upon and is driven by the drum.
  • the present invention relates to a device for controlling take-up bobbins in open end spinning machines.
  • the control device of the invention is particularly useful with spinning machines of the pressure spinning chamber type, although it is obviously not limited thereto.
  • Spinning machines of the type mentioned above usually process slivers deposited in spinning cans, or manufacture fine yarns from a thin sliver or a thick roving.
  • the final product i.e. the yarn thus manufactured, is usually wound on to cylindrical or conical bobbins in a manner similar to that in winding machines.
  • the dimensions of these bobbins depend on the construction of the take-up mechanism and, if said dimensions are satisfactory, the thus wound bobbins can be used directly during further processing.
  • Modem winding machines are also provided with yarn clearers which remove yam slubs as well as other defects which are undesirable in the further processing of the yarn, e.g. by weaving or knitting.
  • yarns produced in open end spinning machines usually show good properties from that viewpoint; however, the occurrence of slubs such as knots due to the manual removing of yarn breakage is not eliminated.
  • the take-up bobbins may be mounted either in the upper or in the lower part of the machine.
  • the bobbin is rotatably driven either by means of a continuous take-up cylinder and independent yarn distributors, or directly by a winding drum.
  • the bobbin holder Upon removing yarn breakage, the bobbin holder is swung by the attendant from the take-up cylinder or the winding drum into a fixed rest position and the yarn endfrom the wound bobbin is then introduced into the spinning unit.
  • the attendant must react immediately, after the catching-up of the yarn end in the spinning unit, to drive the take-up bobbin by bringing it into contact with the take-up cylinder or the winding drum.
  • the path along which the take-up bobbin has to be swung from its rest to its operative position is rather long, particularly when the diameter of the take-up bobbin is small, thus causing a yarn end which is too long to be introduced into the spinning chamber, and thereby subjecting such end to too long a spinning.
  • the elements needed for this operation are also inconveniently positioned, so that the attendants reaction is unduly delayed. This causes, in turn, a longer time than should be necessary for removing the yarn breakage, and results in a lower quality of the manufactured yarn.
  • the device according to the present invention has the purpose to mitigate the disadvantages inapparatus known hitherto, particularly by accelerating the removal of yarn breakage and thus simultaneously improving the quality of the manufactured yarn.
  • the advantages of the device according to the present invention are that it is of simple construction, is reliable in its operation, and substantially improves the performance of the attendant when removing yarn breakage.
  • the last result is achieved by enabling the attendant to lift the wound bobbin at any winding diameter for only the minimum distance which is necessary to disengage the bobbin from the driving cylinder or the winding drum, and to drop said bobbin, upon removing yarn breakage, immediately into its working position in driving engagement with the cylinder or drum.
  • the bobbin holder is connected by means of a connecting element with a control mechanism which selectively secures the bobbin holder in a swung-out position, the control mechanism being provided with a releasing lever for returning the bobbin holder with the winding into the working position.
  • F161 is a schematic view, partially in elevation and partially in vertical section of an arrangement of the device according to the present invention in a first embodiment of spinning machine;
  • FIG.2 2 is a similar view of an arrangement of the device according to the present invention on a second embodiment of spinning machine
  • FIG.3 is a view of a first embodiment of the device accorddevice according to the present invention, the view being par tially in side elevation andpartially in section;
  • FIG.7 is a schematic view of a fifth embodiment of the device according to the present invention, the view being partially in side elevation and partially in section.
  • Spinning machines of the type mentioned above consist of a plurality of identical spinning units, of which each is provided with the device according to the present invention. It is thus necessary to describe only one spinning unit in each of its modifications shown herein.
  • FIG] the control mechanism of the present invention is shown applied to a system wherein yarns 4 are produced from a plurality of slivers 26. Such slivers are withdrawn from a plurality of spinning cans 27 and introduced into spinning units 5 which are of the type having a spinning chamber which operates under pressure. Yarn delivered from the spinning units through tubes shown at the upper ends'thereof are pulled upwardly by feeding rolls 9,9 and are then delivered to a drum or cylinder 3 which drives a bobbin 1 being wound; the drum or cylinder 3 is provided with means (not shown) whereby the yarn is laid upon the bobbin as by being crosswound thereon.
  • the bobbin 1 is rotatably mounted upon a frame which is shown pivotally mounted at 2a whereby the frame and bobbin may rise as the diameter of the bobbin progressively increases.
  • the bobbin shown at the left rests upon and is being driven by the drum 3; the bobbin la at the right is shown as having been lifted by its supporting frame from driving engagement with its cylinder 3, as during the removal of a yarn breakage.
  • the bobbin-supporting frames are provided with levers or arms 2 at their outer ends whereby the bobbins and frames may be lifted into the position shown at the right.
  • the control device 6, (which is shown more particularly in FIGS.3 and 4) includes a rod 7 which is pivotally mounted to the bobbin-supporting frame and which maintains the frame and bobbin in their elevated position as shown at the right in FIG. 1.
  • the control device 6 is also provided with a foot operated pedal 8 whereby the rod 7 may be released when'desired so that the frame and bobbin may be lowered into operative position.
  • FIG.2 the control mechanism 6 is shown applied to a system wherein yarns 4 are produced from rovings supplied by bobbins 29 positioned above the spinning units 5. As shown, the rovings 28 travel downwardly from their supply bobbins into the spinning units 5, yarns 4 produced therefrom then travelling downwardly and finally upwardly to a bobbin-supporting and driving drum or cylinder 3, as in FIG.1.
  • the control mechanisms 6 in FIG.2 have the same relationship with respect to the bobbin-supporting frames and the driving cylinders3asin FIGJ.
  • control mechanism 6 there is employed a stationary yoke 12, mounted on the machine frame and provided with a horizontal pivot pin 11 on which an arm 10 is swingably mounted.
  • the arm 10 has a flange on its upper end, such flange having an opening therethrough receiving the rod 7 which, as we have seen, is
  • the sliver 26 from the spinning cans 27 (FIGJ) or the roving 28 from bobbins 29 (FIG.2) is fed into the spinning unit 5, which manufacture yarn in a known manner.
  • Yarn discharged from the spinning units 5 isfed upwardly by the cooperating withdrawing rollers 9, 9, the yarn then travelling to the winding cylinder or drum 3 which both support the bobbin and the bobbin-supporting frame and drives the bobbin to take the yarn up thereon.
  • the control mechanism 6 is in its inoperative position, the weight of the bobbin and frame being sustained, as above explained, by the winding drum 3.
  • the control mechanism 6 of FlG.3 may be modified to provide means for retarding the downward motion of the rod 7.
  • One such means is shown in FlGA wherein the control mechanism is designated 6.
  • a braking roller 14 is mounted on a horizontal pivot pin on the member 10, the roller 14 being in contact with the rear surface of the rod 7 upon the swinging of member 10 outwardly by the pedal 8. Upon such a release of the clamping means in mechanism 6' the roller 14 engages the rod 7 so as to exert a braking action thereon, thereby slowing the descent of the bobbin and its supporting frame.
  • control mechanism 6a having a toothed segment or bar 7a attached to one or more arms 2 of the bobbin-supporting frame.
  • the radially outer surface of the segment 7a is coaxial of the pivot shaft 2a, and is provided with' a plurality of ratchet teeth as shown.
  • the control mechanism 6a is completed by a pawl in the form of a bell crank lever pivoted at its central zone on fixed structure (not shown).
  • the pawl is constantly urged toward engagement with the gear teeth on the segment 7a by a coil compression spring 15.
  • the pawl is lifted from operative engagement with the I ratchet teeth by pressing downwardly in the direction S upon a pedal secured to the outer arm 7a of the pawl-carrying member.
  • a selectively operable clamping mechanism cooperating with the member 7b takes the form of an eccentric 8c which is pivotally mounted upon a pivot pin 17 affixed to fixed frame structure.
  • the eccentric has an arm 8b affixed thereto, the other end of the arm bearing a pedal.
  • the arm is constantly urged in a clockwise direction (FIG.6) by a coil compression spring 16 interacting therewith.
  • the configuration of the eccentric 8c is such that as it is rotated clockwise by the spring 16 a longer radius portion thereby is presented to the rear arcuate surface of member 7b, thereby to clamp it.
  • FIG.7 there is shown a fluid operated control mechanis 6d.
  • the upper end of the piston rod 7d is pivotally connected to the bobbin-supporting frame, as shown.
  • the lower end of rod 7d carries a piston 18 which reciprocates in a vertically disposed cylinder 19 affixed to fixed frame structure, as shown.
  • the cylinder 19 is disposed within an other larger cylindrical tank 22 which serves as a sump for the system, the sump in this instance containing an hydraulicfluid.
  • the lower end of cylinder 19 is provided with a selectively operated check valve 21 which permits liquid freely to rise from the sump into the cylinder 19 but prevents escape of such liquid from the cylinder unless the check valve 21 is opened.
  • a liquid-throttling sieve or screen 20 is afiixedly positioned in the lower end of cylinder 19 beneath the piston 18.
  • the check valve 21 is operated by a two-armed lever pivoted to fixed frame structure by a pivot pin 17d. The first of inner arm. of such lever underlies the operating stem for the check valve 21, the second outer arm of the lever having a pedal 8d on its outer end.
  • the mechanism 6d may be modified, should it be desired to employ a gas such as air rather than a liquid therein. If atmospheric air is imployed the sump 22 can be dispensed with. Upon the raising of the bobbin-supporting frame 2, air from the atmosphere is sucked into the lower end of cylinder 19 through the check valve 21. The check valve 21 closes the lower end of the cylinder after the upward motion of the piston 18 has stopped. The frame and bobbin continue to be supported by the air cylinder 19 until the check valve 21 is opened by the depressing of the pedal 8d. As with liquid, the screen also acts as a metering means for the flow of air therethrough, so that the descent of the frame and bobbin is slowed upon the opening of the valve 21.
  • a gas such as air rather than a liquid therein.
  • an open end spinning machine including a yarn winding apparatus having a driven rotatable drurn, a frame movable toward and away from the drum, means onthe frame rotatably mounting a bobbin being wound by surface engagement with the drum as the bobbin is thrust toward the drum, the improvement which comprises means for selectively moving the bobbin continuously and steplessly into a selected position away from the drum to stop the winding operation, means for retaining the frame with the peripheral surface of the bobbin in said selected position spaced from the drum, and means for releasing the last named means so that the frame approaches the drum and carries the bobbin into driving engagement with the drum.
  • Apparatus according to claim 1 wherein the means for selectively moving the bobbin away from the drum is positioned to be operated by the hand of an operator in a normal position, and the means for releasing the frame retaining means is adapted to be operated by the foot of the operator in substantially the same normal position.
