Definitions

  • This invention relates to spinning frames having bowl spindles mounted side-by-side and running at high speeds and suitable for making yarns with a prescribed twist from rovings or slivers of textile fibers.
  • Such spindles are most frequently driven by a belt which is either a friction or tangent belt making contact with a pulley integral with each spindle, or an endless driving belt engaging a pulley on each spindle and a pulley carried by a common drive shaft.
  • a friction belt If a friction belt is used, it cannot in practice be driven at a higher linear speed than about 30 m/sec. In the present state of the art, however, there is a tendency to run the spindles at ever-increasing speeds of the order of 50,000 rpm, and great difficulties are encountered in attaining such speeds by direct friction between a friction belt and a pulley, since the spindle pulleys are of insufiicient diameter. Moreover, it is necessary for cleaning or inspection to detach the spindles, and the presence of such a friction belt not only hinders access to the spindles but also impedes the execution of the necessary operations.
  • the known arrangements involve a first movement for ensuring disconnection of the spindle, and a second movement to enable visual or manual access to the interior of the spindle for the purpose of inspection and cleaning.
  • An object of the present invention is to provide a spindle mounting and drive therefor so that the aforesaid disadvantages of existing devices are eliminated or reduced, and disconnection and access are possible in a single movement.
  • a spinning frame of the kind having spindles comprising a fixed part and a rotary part, in which the rotary part of the spindle is mounted freely rotatable on one end of an arm which is pivotable at its other end on a rod at right angles to the axis of the fixed part of the spindle, in such manner as selectively to occupy either a working position wherein it is maintained by releasable locking means and the rotary part of the spindle coacts with the fixed part, or an inspection position wherein the rotary part of the spindle is disengaged from the fixed part, with a rotary drive for the spindle being provided by a step-up belt drive through the intermediary of a small pulley secured to the rotary part and a large pulley freely rotatable on a shaft carried on the arm in the vicinity of said rod, the large pulley being connected to a third pulley of smaller size associated with a friction-d
  • the step-up belt drive can be used to impart very high speeds of rotation to the spindles .without thereby necessarily driving the belt at higher linear speeds than have hitherto been used.
  • the pivotal movement of the arm carrying the rotary parts of the spindle can be effected without any trouble and without it being necessary even to touch the belts used; the friction belt being, moreover, disconnected by this same pivotal movement, automatically, since the pulley coacting therewith is withdrawn from contact therewith, when in the inspection position. In that position, the inside of the bowl spindle is readily accessible so that the inspection and cleaning operations can be conveniently and quickly completed.
  • this arrangement allows the provision of very simple braking means which consists merely of an ordinary brake shoe carried on the spindle frame with which the pulley driven by the friction belt frictionally engages when the carrier arm is moved into the inspection position.
  • the end of the arm carried on the rod is in the form of a spring clip with two arms passing around the rod in such manner as to be detachable therefrom.
  • the assembly consisting of the arm and the whole rotary part of the spindle can thus be handled as a unit together with the step-up belt drive, and this is most convenient for maintenance and repairs.
  • FIG. 1 is a vertical section on the line II of FIG. 2 of part of a spinning frame in accordance with the present invention, and shown in the working position;
  • FIG. 2 is a horizontal section on the line IIII of FIG. 1;
  • FIG. 3 is a view corresponding to FIG. 1, and in the inspection position.
  • the section of a spinning frame shown in the drawings comprises a longitudinally extending support 1 along which regularly-spaced spinning spindles are fitted, each as a whole designated by 2.
  • Each spindle 2 comprises a fixed part 3 constituting stationary spinning means attached to the support 1 by screws 4, and a rotary part 5 constituting rotary spinning means arranged immediately underneath the fixed part 3 and carried on an arm 6, of which one end is pivotable on a horizontal rod 7 with the rod being at right angles to the axis of the fixed part 3.
  • the rotary part or bowl 5 of the spindle is attached to a pulley 11, which is freely rotatable on two ball bearings 12, 13 on a central tube 14 secured to a boss 15 held in place at one end of the arm 6 by a nut 16.
  • a boss 15 held in place at one end of the arm 6 by a nut 16.
  • a block 22 On the same end of the arm 6, there is fixed by means of the boss 15 and a screw 21, a block 22, on which attached by screw 23 is an annular member 24 which has an annular recess locating a packing ring 26 which bears on a corresponding conical surface 27 of the fixed part 3 of the spindle.
  • the other end of the arm 6 is in the form of a spring clip consisting of an upper jaw 31 formed by bending the end of the arm 6 into the form of a part of a cylindrical surface fitting the cylindrical surface of the rod 7 over nearly a semicircle and a lower jaw 32 consisting of a spring blade attached on the arm 6 by a bolt 33 and which is similarly bent in the fonn of a part of a cylindrical surface making contact with the cylindrical surface of the rod 7, also over nearly a semicircle.
  • the jaws 31 and 32 end in two beaks 37 and 38, enclosing therebetween a dihedral angle which facilitates the fitting of the clip over the rod 7.
  • the upper jaw 31 is in the form of a fork with prongs 31A and 3113 (FIG. 2) which embrace an axially-locating ring 41 fitted to the rod 7 and held thereon by a set screw 42.
  • the lower jaw 32 is similarly forked, with two corresponding arms.
  • the arm 6 is held in the working position shown in FIG. 1, by means of a catch consisting of a leaf spring 45 of which the upper end is attached to the fixed part 3 by a screw 46 while its lower end has a hole 47 fitting over a stud 48 attached to the block 22.
  • a catch consisting of a leaf spring 45 of which the upper end is attached to the fixed part 3 by a screw 46 while its lower end has a hole 47 fitting over a stud 48 attached to the block 22.
  • the spring 45 By moving the lower end of the spring 45 in the direction of the arrow f1, the spring can be disengaged from the stud 48, so that the arm 6 can drop into the inspection position shown in FIG. 3, by pivoting on the rod 7 in the direction of the arrow f2, with the length of the swing being limited by a stop 51 (FIG. 3) fitted to the support 1.
  • the dimensions and the strength of the spring clip 31 by which the arm 6 is held on the rod 7 are so selected that the arm can be released from the rod by pulling in the direction of the arrow f3, after having released the catch 45.
  • the arm 6 can easily be restored to its original position by placing the beaks 37, 38 against the rod 7, so that they spread apart when the arm 6 is pushed in the opposite direction to the arrow f3.
  • the bowl of the spindle is rotated by a friction belt 54 running parallel to the rod 7, a transmission gear comprising the pulley 11, an endless belt 55 passing around the pulley 11, a second pulley 56 around which the belt 55 also passes, and a third pulley 57 integral with the pulley 56 and on which the friction belt 54 bears when the arm 6 is in the working position as shown in FIG. 1 and 2.
  • the pulley 56 is of greater diameter than the pulley 57.
  • the pulleys 56 and 57 are carried on a vertical shaft 58 freely rotatable in two ball bearings 61, 62, in a cup 59 having a threaded end bolt formed by the bolt 33 referred to earlier.
  • the pulley 57 bears with friction against a brake shoe 71 attached to the lower end of a tongue 72, preferably somewhat elastic, of which the top end is attached to the support 1 by a bolt 73.
  • the upper, fixed part 3 of the spindle has a nozzle 75 coaxial with the rotary bowl 5 and an aperture 74 for the entry of the rovings of textile fiber to be spun.
  • the nozzle 75 can be inserted into the fixed element 3 from below same (see in particular FIG. 3), when the arm is swung down. It has an axially locating ring 76 bearing against an annular shoulder 77 on the fixed part 3 and an elastic system for angular positioning consisting of two, diametrally-opposed plungers in the form of balls 81 urged by springs 82 inside radial, blind holes 83 in the nozzle 75, with the balls 81 entering partially into corresponding radial holes 85 in the upper portion of the fixed part 3.
  • the rotary bowl 5 In the working position shown in FIG. 1 and 2, the rotary bowl 5 is in the upper position ready to coact with the fixed part 3, while the pulley 57 bears against the friction belt 54 in such manner that the latter, through the intermediary of the step-up belt drive 55, rotates the bowl 5.
  • the top nozzle 75 can be conveniently removed and refitted.
  • the arm 6 and the elements it carries can be completely and instantaneously removed, viz: the rotary part 3 of the spindle, and the step-up belt transmission gear 55.
  • a spinning machine having a frame and spindles carried by the frame, each spindle comprising a fixed part and a rotary part a rod carried by the frame and located at right angles to the axis of the fixed part of the spindle, an arm having opposite ends, said rotary part being freely rotatable on one end of the arm, the other end of the arm being pivotable on the rod in such manner as selectively to occupy either a working position in which the rotary part of the spindle coacts with the fixed part, or an inspection position in which the rotary part of the spindle is disengaged from the fixed part, releasable locking means cooperable with the fixed part and the movable part to maintain said parts in the working position, a rotary drive for the spindle said drive including a small pulley secured to the rotary part, a shaft carried by the arm adjacent the rod and extending perpendicularly to the arm, a large pulley freely rotatable on said shaft, a third pulley of lesser diameter
  • the spindle has a nozzle for the admission of the fibers, a socket in the fixed part in which said nozzle is fitted, and quick release and attaching means for the nozzle.
  • a spinning machine having frame means, and at least one spinning unit comprising stationary spinning means carried by the frame means and rotary spinning means including a first pulley and a spinning chamber mounted on the first pulley for rotation therewith, a rod supported by said frame means, an arm having opposite ends, one end of said arm being connected to said rod for swinging movement relative to the stationary spinning means, said first pulley being mounted on said arm for swinging movement therewith between an operative position in which said chamber cooperates with said stationary spinning means to spin a yarn and an inspection position in which said chamber is spaced from said stationary spinning means, a second pulley mounted on said arm so as to lie between the first pulley and said rod, said second pulley having two cylindrical length portions of different diameter, a friction drive belt engaged by the smaller diameter portion of said second pulley only when said chamber is in its operative position, and a drive transmission belt trained over said first pulley and the larger diameter portion of said second pulley.
