Definitions

  • This invention relates to a process and apparatus for fiber band spinning. More particularly, this invention relates to a process and apparatus for the automatic return of a thread end to the fiber collecting surface of a fiber band spinning machine.
  • the building-up of the thread reserve ahead of the doffing rollers produces a variation of the thread number as a result of nonuniform doffing speed, or else the build-up has to take place over a long period of time, during which the mechanism is not in a position to return the thread reserve needed for respinning.
  • an arrangement as in German Democratic Republic Pat. No. 65,362 is not satisfactory in this respect, because the use of rollers in the deviating guidance ahead of the doffing rollers obstructs the rapid release of the thread reserve, or in the case of a thread reserve beyond the doffing rollers, requires additional control or actuation of the rollers so as to release the thread by a rapid lifting of the pressure-applying rollers. The greater the force needed for such a release, the more sluggishly does the apparatus respond.
  • the invention provides a method and apparatus in which a thread reserve is created for a spinning machine and is released for backfeeding into the spinning chamber of the spinning machine under the suction force of the spinning chamber.
  • the method includes the steps of creating a thread reserve downstream of a set of doffing rollers used to doff the thread from the spinning chamber and of substantially instantaneously releasing the thread from the thread reserve while removing the thread from the nip of the dofi'ing rollers upon the occurrence of a thread break. in this way, it is possible for the thread which is completely free to snap back into the spinning chamber under the suction force created by the chamber during operation. A very rapid response is thus obtained which response is substantially independent of the thread doffing speed.
  • the apparatus of the invention has a thread displacement guide means which is disposed downstream of the doffing rollers, relative to the direction of thread movement, to create an extended path for the thread and thus a reserve loop or thread reserve.
  • This means further is constructed to substantially instantaneously release the thread reserve in response to the detection of a drop in thread tension by a sensing element located adjacent the spinning machine.
  • a thread ejector is disposed upstream of the doffing rollers and substantially parallel to the dofiing rollers to cooperate with the thread displacement guide means. The thread ejector serves to move the thread out of the nip of the doffing rollers upon the detection of the drop in thread tension by the sensing element.
  • the tension in the doifed thread decreases. This causes the thread displacement guide means to release the thread reserve by allowing the thread to be thrown off from the guide means.
  • the thread ejector also forces the thread out of the nip of the doffing rollers. As the thread reserve is then free of restraint, the suction force created by the spinning chamber then draws the thread end rapidly back into spinning chamber for piecing.
  • the thread reserve can be built up substantially in the plane of the nip of the doffing rollers so as to simplify manipulation of the reserve while saving space.
  • the invention provides an apparatus which is extremely simple and inexpensive and which operates practically free of inertia.
  • two fixed-location thread guides can be disposed downstream of the doffing rollers so that the thread reserve is built up therebetween.
  • a plurality of thread displacement guide means of a number of spinning sites can be movable in common in the direction of the reserve loops with each being movable.
  • the guide means can be fixedly mounted and a movable thread displacer may be provided for placing the thread over the guide means.
  • the initial position of such thread displacers can be adjustable in order to allow dimensioning of the length of the piece of thread to be returned.
  • the thread displacers are advantageously disposed at a'number of spinning sites upon a common bar, and are movable with this,in the longitudinal direction of the spinning machine, by means of a common drive mechanism.
  • the thread displacement guide means can be made with a run-on surface, so as to facilitate placement of the reserve loop, the need for a special guiding device is eliminated. If the thread-ejector is made as a clamppart, with which a fixed-location stop is associated as a counter-part, then during stoppage of the spinning mechanism the thread can beheld ready for the resumption of spinning, and can be prevented from emerging out of the spinning mechanism. A mechanism required for lifting the clotting rollers is also eliminated.
  • FIG. 1 shows in a schematic representation the principle of the invention
  • FIG. 2 shows a perspective view of an apparatus according to the invention
  • FIG. 3 shows another embodiment of the invention
  • FIG. 4 shows an enlarged detail of an apparatus of the invention for the building up of the reserve loop with movable thread displacement guide means
  • FIG. 5 shows a modified apparatus for the building up of a reserve loop, in a direction perpendicular to the longitudinal axis of a spinning machine
  • FIG. 6 shows a perspective view of a detail of the thread displacement guide means of FIG. 2;
  • FIG. 7 illustrates an electronic control for the apparatus of FIG. 2.
  • the thread reserve is advantageously built up downstream of the doffi'ng rollers, in order to reduce the frictional load resulting from the spinning tension on the displacement guide means, it is necessary to release the thread held between the doffing rollers. This is ordinarily done by raising the pressure-applying roller of the doffing rollers. To do this, however, requires a powerful mechanism, which is correspondingly expensive and does not operate in an inertia-free fashion. Thus, the thread is instead forced out substantially parallel to the nip line of the doffing rollers and is thus released for return into the spinning mechanism.
  • the principle of this process is shown in FIG. 1, with elimination of all machine elements that do not participate directly in this process.
  • the thread F emerges from a spinning mechanism 8 through a thread-delivery tube 81 and is directed by way of a pair of doffing rollers, consisting of an elongated lower cylinder 5 and a pressure-applying roller 51, to a thread displacement guide means .1 and from there to a thread-guide 31 and beyond that to a wind-on spool 6.
  • a spinning operation the thread F thus assumes the position shown by the solid line.
  • An ejector 2 is disposed upstream (i.e. below) the doffing rollers 5, 51 and is movably mounted so as to be brought into one position 2' by means of a magnet 23 and into a further position 2".
  • the ejector 2 is movable by means of a bar 22, which can be displaced in the direction of the arrow P Where a number of spinning sites are used, a plurality of corresponding ejectors can be mounted in common on the bar 22. In position 2", the ejector 2 presses against a fixed-location clamp abutment 21.
  • a sensing element or feeler 7 is disposed between thethread-delivery tube 81 and the doffing rollers 5, 51 which checks the tension of the thread F.
  • this feeler 7 produces a contact that actuates the thread displacement guide means 1 and also the ejector 2.
  • the thread-displacement guide means 1 is pulled back by a magnet 14, so that the thread is thrown off.
  • the ejector 2 is moved into position 2', so that the thread no longer runs into the nip of the doffing rollers 5, 51.
  • the thread reserve is thus released immediately, and becomes drawn back into the spinning chamber through the underpressure therein.
  • the thread F assumes the position F shown by the dotted line.
  • the spinning chamber initially starts operating. Thereafter, the thread-feed, the doffing rollers and the winding mechanism for the spool are switched on. At the same time, the clamping of the thread F against the abutment 21 is eliminated, in'that the ejector 2 is moved by the bar 22 toward the right as viewed.
  • the thread-feeler 7 thus finds that the spinning tension is lacking, so that, at this same moment, the thread displacement guide means 1 is pulled back, and the ejector 2 by means of the magnet 23 assumes its position 2'. In spite of the shift of the bar 22 into its original position, the thread F is not yet able to run into the doffing rollers 5, 51.
  • the thread displacement guide means 11 are disposed on a common bar 15, which can move in the direction of the arrow P
  • the bar 15 is first moved so far to the right that the displacement guide means 11 comes to rest at the right against the thread F. Then, the bar 15 is moved again to the left into its original position, so that the thread is displaced by the guide means 11 into a loop.
  • the thread displacement guide means 1 is disposed in a fixed location, and can be pulledback by a magnet 14 as-is known only for the purpose of throwing off the thread loop.
  • a thread guide 3 is disposed directly beyond the doffing rollers 5, 51.
  • the thread reserve loop is formed by means of thread displacers 4 constituted by a pair of pins disposed fork-fashion on a movable bar 41 situated above the entire length of the machine. In operation, directly after the release of the thread reserve by the guide means 1, the thread is reintroduced into the nip line of the doffing rollers 5, 51.
  • the thread displacers 4'then move from their position 4 shown by dot-dash lines to the left to push the thread F to the left until it comes to lie over the thread displacement guide means 1.
  • the bar 41 can be moved in the direction of the arrow F, by means of a drive mechanism, for example by means of a motor 43, which engages by a pinion 44 in a set of teeth in the bar 41.
  • a drive mechanism for example by means of a motor 43, which engages by a pinion 44 in a set of teeth in the bar 41.
  • the motor 43 with pinion 44 it is also possible to provide a cam drive or a crank drive for moving the bar 41.
  • the movement of the thread displacers 4 is also initiated by the interruption of the feeler contact when the spinning tension is again obtained.
  • the thread-displacers 4 then lays the thread over the guide means 1, and returns to the original position 4 so that a reserve is formed between the thread-guides 3 and 31.
  • this bar 41 which is able to move in the longitu dinal direction of the machine, it is possible to actuate in common all the displacers 4 for a number of spinning sites.
  • the length of reserve thread needed for automatic start-up depends, among other things, on the material and on the doffing speed. It is therefore desirable to make a central adjustment of the reserve length for all the spinning sites of the machine. This is achieved in that either the initial position 4' of the thread displacer 4 is adjustable, so that the thrown-off thread loop is released not for its entire length but'only for a part of it with a residual deviation due to the displacer 4 or else the magnitude of the lifting movement of the thread displacement guide means 11 (FIG. 3) is adjustable through the drive of the bar 15.
  • the ejector 20 andthe thread displacement guide means 10 can also be coupled directly with one another as through the intermediary of a three-arm lever mechanism.
  • a fork-shaped dis-' placement guide means 10 is mounted on one lever arm 16 while the ejector 20 is mounted on a second lever arm 24.
  • a magnet 18 acts by an armature 19 on a third lever arm 17.
  • the three lever arms 16, 24, 17 are fastened on a vertical shaft 25 to rotate with the shaft 25.
  • the thread displacer 4 pulls the thread F into a reserve loop, and lays it over the guide means 10. So that the thread F can be laid better and without guidance over the guide means 10, the guide means 10 is provided with a run-on surface 13 which deflects the thread into position. The thread F can thus become pushed through the displacer 4 over the guide means 10.
  • the feeler 7 determines that there is a diminution of the thread tension, the feeler 7 closes the circuit for the magnet 18.
  • the armature 19 presses against the lever 17, whose pivoting movement is transmitted to the two other levers 16 and 24.
  • the thread-displacement guide means 10 is pulled back in opposition to a fixedly mounted stripper 9, so that the reserve loop is thrown off.
  • the ejector 20 forces the thread P out of the nip line of the doffing rollers 5,51, so that the reserve loop can be drawn back into the spinning mechanism 8.
  • the feeler 7 interrupts the circuit of the magnet 18, and the ejector 20, together with the guide means 10, are, via a spring 26, brought back into their original position.
  • the thread displacer 4 comes into operation for the'purpose of forming a new thread reserve by laying the thread F upon the displacement guide means 10.
  • the feeler 7 has a contact which is closed in its fundamental position, that is, when the thread tension is correct, through which a switch-unit 62 is interrupted (or open) and the magnet 18 is in a nonexcited state. If, through a diminution of the thread tension, the feeler 7 becomes interrupted, then the switchunit 62 is closed, and supplies a brief pulse to the magnet 18 in order to cause a throwing off of the reserve loop and to cause a forcing of the thread F out of the nip line of the doffing rollers 5, 51.
  • the thread F by means of the lower-pressure prevailing in the spinning mechanism 8, is drawn back into the mechanism 8 and the connection with the fibers fed into the spinning mechanism 8 by a feed device 82 is restored. If this connection cannot be produced within a certain interval of time, then the switch-unit 62 actuates a magnet 83 for stopping the feed device 82, until the thread doffing tension is again restored at the feeler 7.
  • the buildup of the thread reserve can be accomplished in two ways:
  • the periodically operating control device 66 then periodically emits suitable signals to the switch-unit 63 which then, as described, actuates the bar 41 through the motor 64.
  • This arrangement is also suitable for resuming spinning after a standstill of the machine.
  • the thread F remains in the nip of the dofiing rollers 5, 51 during standstill and thus is prevented from emerging out of the thread delivery tube 81.
  • the pressure-applying roller 51 is raised before release of the thread reserve is effected, and after this release is set on again. This is done, for example, by means of a cam 54 which is able to turn with a shaft 55 and presses against the free end of a lever 52 which is able to pivot about an axle 53 and which carries the pressure-applying roller 51 thereon.
  • the displacing guide means 10 as shown in FIG. 6 is provided with a delimiter of the thread path in the form of a triangular eye 12.
  • This eye 12 is arranged so that the moving thread F cannot run off over the free end of the guide means 10.
  • the eye 12 is fastened elastically to the stripper 9, so that the thread displacer 4 can push it aside for the purpose of laying the thread F on the guide means 10.
  • the cam 54 can, for example, be driven by a motor 56, whereby the motor 56 comes into operation by means of the main switch arrangement 57 at the starting-up of the machine.
  • This main-switch device 57 also controls in a chronologically correct sequence, the setting into operation of the spinning chamber 8, of the feed device 82, and so forth.
  • the thread reserve in order to conserve space, is built up parallel to the iongitudinal axis of the machine so as to be situated substantially in a plane going through the nip of the doffing rollers.
  • the purpose of the invention is however, not dependent on this arrangement.
  • a horizontal spinning mechanism 8 has the thread reserve loop disposed outside the nip plane and perpendicular to the longitudinal axis of the machine.
  • the thread reserve is, as has already been described, by means of displacers 4 laid over a thread displacing guide means I, and thrown off therefrom for feeding back into the spinning mechanism 8.
  • the displacers 4 are fastened on a bar 42 which can be moved perpendicularly to the longitudinal axis of the machine.
  • a shaft 45 is disposed parallel to the doffing rollers 5, 51, and a pinion 44 for each spinning site is fastened thereon.
  • Each pinion 44 is connected with the bar 42 by means of teeth thereon.
  • the bar 42 can be moved to and fro in the direction of the arrow P by the pinion 44, Here too, a common adjustment of the position of displacement for dimensioning the length of the fed-back thread F is possible.
  • the thread F Prior to its release and during normal spinning operations, the thread F assumes the position shown in solid lines, whereas after the release of the thread reserve, the thread runs as shown by the line F over the displacer 4 and the thread-guide 31 before being wound on the spool 6 by way of the spooling roller 61. For the rest, the functioning of the parts is the same as has already been described.
  • the invention is not limited to the forms of construction shown. These merely represent examples for explaining the principles of the invention. It is easily possible to interchange individual elements of the illustrated forms of construction. For example, in the case of the design of FIG. 5 instead of using the thread displacer 4, it is possible to use the movable thread displacing guides 11 according to FIG. 3. It is also possible, for example, to replace the retractable thread displacing guide means 10 by one that is fixed in location opposite which the stripper 9 is movable, by means of a suitable coupling to the lever arm 16.
  • the invention thus provides an automatic means of returning a broken thread to a spinning machine for piecing.
  • the apparatus provided is relatively inexpensive and, as such, does not have any substantial effect on the overall cost of the spinning machine.
  • spinning chamber for which the invention is applicable includes pneumatic operating spinning as spinning rotors (of U.S. Pat. No. 3,440,812), rotatable or fixed spinning funnels (Czech Pat. No. 87,947 and Japanese Patent application 38/24,05l) or chambers in which the fibers moving with a medium join a freely rotating thread end(U.S. Pat. No. 2,911,783).
