Definitions

  • SHEEI 5 If 6 METHOD AND APPARATUS FOR BRAKING FILAMENTARY MATERIAL UNWOUND FROM A PACKAGE This invention relates to a method and apparatus for braking filamentary material unwound from a package, particularly, by over-end unwinding.
  • the yarn must bend aside each bristle tip consecutively to reach the next bristle, and so on.
  • the yarn is thus placed under considerable stress so that, if the yarn is used as a weft yarn for picking in a weaving machine, there is a relatively great likelihood of weft yarn breakage.
  • the yarn must be braked under relatively slight forces.
  • the brake ring is required to have soft bristles.
  • the brake ring bristles must have some strength for concentric retention of the ring and for synchronous running of the ring and the rotating package.
  • the invention provides a method of braking an over-end winding of filamentary material, for example, yarn, thread, etc. from a substantially cylindrical storage drum in a storage device for textile machinery for further processing of the material, for example, for picking as weft yarn in the shed of a weaving machine.
  • the method comprises the steps of forming a supply of wound coils of filamentary material on the storage drum, of unwinding the filamentary material over one end of the storage drum while forming a balloon; and of applying a braking force on the filamentary material from the interior of the balloon in the region of the balloon to brake the filamentary material.
  • the braking force can be applied in any suitable manner, such as mechanically or pneumatically, to brake the filamentary material to a stop, for example, at the completion of a picking operation of the filamentary material in a weaving machine.
  • the invention also provides a storage device for receiving a plurality of coils of filamentary material, for example, for subsequent delivery to a shed in a weaving machine, with an apparatus for braking the filamentary material unwound over-end from the storage device from the inside of a balloon formed by the material unwound from the storage device.
  • the apparatus comprises a brake means disposed within the balloon for directing a braking force from within the balloon outwardly relative to the balloon.
  • This brake means can be of a mechanical type or a pneumatic type.
  • the brake means is in the form of an annular brake member mounted in one end of the storage device with flexible elements, such as bristles, directed outwardly towards the balloon.
  • This brake member can cooperate with a balloon limiter means or not.
  • the brake means is in the form of an inflatable tube which is adapted to press the filamentary material against a balloon limiter disposed concentrically about the storage device.
  • the brake means is in the form of a nozzle which directs air flows outwardly to press the filamentary material against a balloon limiter.
  • the yarn is driven away from the operative brake means during unwinding as a result of the centrifugal force present in the yarn balloon during unwinding.
  • an annular brake member with bristles is used in combination with a balloon limiter
  • the yarn always runs over the tips of the bristles as a result of centrifugal force and at the same time along the inner surface of the balloon limiter.
  • the bristles are thus only bent slightly by the yarn in the direction of movement, if at all, and the yarn is therefore subjected to very little stress.
  • yarn breakages can be prevented during further processing, for example, during picking of the yarn into the shed of a weaving machine.
  • FIG. 1 illustrates a cross-sectional view through a weaving machine weft yarn storage device utilizing an apparatus constructed according to the invention in a partly diagrammatic representation
  • FIG. 2 illustrates an enlarged view of a detail of FIG.
  • FIG. 3 illustrates a view of a modified brake member which is adjustably mounted in a storage device
  • FIG. 4 illustrates a cross-sectional view of a further modification of a brake member according to the invention
  • FIG. 5 illustrates a cross-sectional view of a modified braking arrangement according to the invention
  • FIG. 6 illustrates a cross-sectional view of a modified braking means using a ring-like balloon limiter
  • FIG. 7 illustrates a cross-sectional view of a pneumatic braking means according to the invention
  • FIG. 8 illustrates a view taken on line 88 of FIG. 7.
  • FIG. 9 illustrates a cross-sectional view of a modified braking member in the form of an inflatable annular tube.
  • a storage device for storing a length of filamentary material for subsequent delivery to a shed of a weaving machine includes a machine frame 1 in which a rotatable member 3 is mounted via a ball bearing 2.
  • the member 3 houses a hollow shaft 4 which is rotated by a belt drive 5.
  • a w bular yarn guide 6 which extends outwardly at an angle is connected to the hollow shaft 4 and passes through a protective ring 7, which also rotates.
  • the hollow shaft 4 continues, to the right as shown, in the form of a shaft stub 8, on which a cylindrical winding drum 9 is disposed to be rotatable, for example, via ball-bearings (not shown in detail).
  • the drum 9 is secured against rotation by a permanent magnet 11 which is disposed in the member 1 and which cooperates with a permanent magnet 12 fastened in the drum 9.
  • the right-hand end of the drum 9, as viewed, has a bevelled bead 13 as well as a recess within the bead 13.
  • a brake ring 15 provided with bristles 14 is secured to the end face of the drum 9 within the recess by means of one or more locking bolts as shown.
  • the bristles 14 are directed against a balloon limiter ring 16 disposed in the machine frame 1 and, as illustrated, contact the ring 16 by the tips 17 of the bristles.
  • the balloon limiter ring 16 is mounted in a bearer ring 18 which can be loosened from the frame 1 by means of a screw 19.
  • a yarn 21 passes from the left, as viewed, through an eye 22 in the hollow shaft 4 and then via the shaft 4 and yarn guide 6 to an entry cone 23 of the drum 9.
  • the first partial turn 24 running onto the cone 23 slips to the right, as viewed, so that the other prior turns 25 continuously slip to the right on the drum 9.
  • the winding 28 is monitored at the right-hand end by means of a photoelectric control device 27.
  • the control device 27 stops the drive of the hollow shaft 4 so that, as the unwinding of the weft yarn 21 progresses to the right, the length of the winding decreases.
  • the drive of the shaft 4 is then started again so that more yarn is wound onto the drum 9, and so on.
  • a yarn balloon 31 forms in the region of the end of the drum 9 from which the yarn is unwound and is limited by the funnel-shaped balloon limiter ring 16.
  • the centrifugal force in the balloon 31 ensures that the yarn 21 constantly runs along the inner surface 32 of the balloon limiter. The yarn is thus taken past the outer tips 17 of the bristles 14 by centrifugal force and is braked.
  • the frame 1 has an inclined slot 33 through which the screw 19 is introduced.
  • the screw 19 can be adjusted in the slot 33 both in the axial region H and in the radial region B (FIG. 2).
  • the balloon limiter ring 16 is passed from the position 16a shown in solid lines in FIG. 2, in which the ring 16 contacts the bristles 14, into the chain-line position 16b to an increasing degree, in which position there is a clearance L between the tips 17 of the bristles and the balloon limiter ring 16.
  • the yarn describes the balloon 31, while with the clearance L, the yarn describes the balloon 31a.
  • the brake ring 15 has a ring 37 on the inside which is adapted to slide to and fro in the direction indicated by the arrow 36 and be locked in place.
  • the ring 37 allows the bristles 14 to be supported particularly in the region of their tips 17 so that, in the position 37a shown in broken lines, the tips 17 produce an increased braking effect at the balloon limiter ring 16.
  • a limiter ring can be eliminated where a brake ring 15a has bristles 14a which extend outwardly at an angle and which are inclined in the direction of rotation of the balloon 31 so that the yarn 21 passes through the bristles 14a.
  • the yarn 21 is thus braked at the bristles 17 over which the yarn balloon 31 runs.
  • the bristles or their tips are so cut that each bunch of bristles forms a curvature 17a on the outside whereby the yarn 21 always undergoes maximum braking at the highest point, while remaining steady in the gaps 17b during picking intervals.
  • the yarn 21 is directed through a guide ring to the right, as viewed, prior to passage, for example, to the picking mechanism of a weaving machine.
  • the braking ring 15b is mounted on the periphery of the drum 9 upstream of the lead 13 while the bristles 14 are disposed in a plane perpendicular to the axis of the winding drum 9.
  • the bristles 14 contact the limiter ring 16 to press the yarn 31 against the limiter ring 16 under a braking force sufficient to brake the yarn 21 when unwinding is interrupted but insufficient to interfere with unwinding of the yarn 21 during normal unwinding.
  • a ring 42 is disposed on the frame 1 and cooperates with the bristles 14 of a brake ring 15.
  • This ring 42 may be mounted in a mount 43 so as to be fixed or rotatable. If required, the ring 42 can be kept in synchronism with the drum 9 by any suitable means.
  • the ring 42 acts as a balloon limiter against which the bristles 14 contact for the above purpose braking the yarn 21.
  • a yarn guide is mounted on the frame 1 downstream of the brake ring 15 via a bracket to direct the yarn, e.g. to a picking mechanism in a weaving machine.
  • a ring 15c is secured on the end face of the drum 9.
  • the ring 15c has a conical outer part 51 in which a plurality of air exit nozzles 52 are disposed.
  • the nozzles 52 connect to a source of compressed air via suitable passage means (not shown) so that jets of compressed air 53 can be expelled in the direction indicated during operation.
  • a turbulent flow of air in the direction indicated by arrow 55 forms in the intermediate space between the ring and the balloon limiter 16 and is directed in opposition to the rotation of the yarn 21.
  • the yarn is thus held and braked at the inner surface 32 of the balloon limiter ring 16.
  • the compressed air supply may be controlled in the rhythm of a weft pick so that, during the unwinding of the yarn, a short air turbulence is produced in the direction of arrow 55 while during the picking intervals, no air emerges from the nozzles 52.
  • the limiter ring 16 may have radially disposed holes (not shown) for the air exit.
  • a liquid for example, water, may also be used as a flowing medium for injection through the nozzles 52.
  • the brake means may alternatively be an air-inflated tube 57, for example, rubber or plastics, which bear against the inner surface 32 of the balloon limiter ring 16 and which is disposed on a ring d, for example, being glued thereon.
  • All the brake means illustrated act from the inside 20 of the balloon 31 on the yarn 21 or other material, so that the yarn 21 is braked.
  • This braking is desirable to prevent further turns 25 from being drawn off from the drum 9 as a result of the inertia forces of the yarn 21 acting, for example, in the region of the balloon 31 towards the end of the picking operation when the picked piece of yarn is suddenly stopped. In this respect, it is required that the unwinding of turns of yarn, etc. should stop immediately when no more yarn is picked into the shed.
  • a method of braking an over-end winding of filamentary material comprising the steps of forming a supply of wound coils of the filamentary material on a storage device; unwinding the filamentary material over one end of the storage device while forming a balloon; and
  • an apparatus for braking the filamentary material unwound over-end from said storage device from the inside of a balloon formed by the material unwound from said storage device comprising an annular brake member disposed within said balloon and having flexible elements directed outwardly towards said balloon for directing a braking force from within said balloon outwardly relative to said balloon.
  • said storage device is a substantially cylindrical drum and said brake member is an annular ring mounted concentrically about a periphery of said drum at one end thereof.
  • an apparatus for braking the filamentary material unwound over-end from said storage device from the inside of a balloon formed by the material unwound from said storage device comprising a brake means disposed within said balloon for directing a braking force from within said balloon outwardly relative to said balloon, and an annular balloon limiting means disposed about said storage device and said brake means for limiting the size of said balloon, said brake means being directed against said limiting means.
