Definitions

  • the most common way of producing a twine is that in a first stage of work using suitable spinning units, e.g. Rotor spinning or friction spinning devices are made from dissolved fiber material or ring spinning devices, which are spun in a subsequent work step by means of twisting devices, e.g. Double wire twisting devices to be processed into a twine.
  • suitable spinning units e.g. Rotor spinning or friction spinning devices are made from dissolved fiber material or ring spinning devices, which are spun in a subsequent work step by means of twisting devices, e.g. Double wire twisting devices to be processed into a twine.
  • twisting devices e.g. Double wire twisting devices to be processed into a twine.
  • independent spinning machines acting on the one hand and threading machines on the other hand are required, which is complex both in terms of machine and in terms of the workflow.
  • the invention is concerned with the idea of integrating spinning units into a twisting device constructed essentially according to the double-wire principle in such a way that in a continuous working process the filaments produced by means of the spinning units are combined immediately after their manufacture and - in accordance with the double-wire principle - are processed into a twine.
  • thread balloon An essential element in the double-wire twisting process is the thread balloon, in which the thread forms an envelope around the stationary bobbin of the thread spindle, which was previously regarded as impenetrable in order to allow material flows, e.g. also fiber material to feed into the space enclosed by the thread balloon.
  • a first solution to this problem of feeding material flows into the space essentially enclosed by the thread balloon is described in DE-37 21 364 C2.
  • a flow medium is introduced without interference into the space delimited by the thread balloon, in that the spindle rotor has a plurality of guide blades arranged in the form of a spoke and the thread guide channel runs through one of these guide blades.
  • air-conditioned air is also indicated, but also two-phase media, such as drops suspended in air, which are said to have special effects on the yarn. It is also stated that fiber material can be fed in with this method.
  • the invention has for its object to provide a method for producing a thread from at least two components to which the twisted spindle is only fed dissolved fiber material and the finished twisted thread is withdrawn from the spindle.
  • DE-OS 1 785 366 dating from 1972, deals with a spinning process, which at this time is still referred to as "element spinning", in which fiber material is arranged into a fiber band, which is brought into the form of a rotating balloon, in which is given to the sliver at least two turns per revolution of the balloon and the resulting yarn is drawn off.
  • the device for carrying out this known spinning process has a spinning chamber arranged on a spindle, into which the fiber material is introduced through a fiber input tube running coaxially to the spindle axis and a channel running radially through the spindle rotor. Inside the spinning chamber there is a collecting ring for the fiber material, which is formed into a fuse there.
  • the drawn fiber sliver is guided through a channel lying in the spindle axis, in which it receives a first rotation and from which it emerges in the radial direction and enters a rotating balloon surrounding the spinning chamber, in which it receives the second rotation.
  • the thread drawn off from the spinning rotor is returned to the common axis of the spinning rotor and the double-wire rotor by a draw-off channel arranged in the double-wire rotor and running in an arc around the outside of the spinning rotor, and is discharged upwards through the drive device of the double-wire rotor.
  • a second turn is applied to the thread.
  • the fiber material is fed to the spinning rotor through a feed channel in the double-wire rotor, the receiving opening of which is symmetrical and the discharge opening is eccentric to the axis of the double-wire rotor.
  • the basic idea of the invention is to use the fiber material introduced into the twisting spindle through the rotating thread balloon directly for the production of a thread from at least two spun threads and this fiber material so that it does not disturb the balloon on the one hand and on the other hand there is enough space to accommodate several spinning units within the space defined by the thread balloon, to which the fiber material is fed in separate streams, while the spinning threads drawn off by the spinning devices together through the hollow spindle axis and Thread balloon are guided.
  • the space previously occupied by the necessary supply spools is available to the spinning units and their drive mechanism.
  • the spinning and twisting technology process in the open-end spinning-twisting system is as follows: Dissolved fiber material is preferably fed through the thread balloon to the interior of the spindle just above or in the preferably upper region of a thread guide element that rotates with the thread balloon - balloon limiter or thread guide tube. At the point of crossing the fiber stream, the thread is preferably guided through a thread guide element attached to the co-rotating thread guide element.
  • Each fiber stream supplies a spinning unit, for example a spinning rotor.
  • the spinning rotors are driven by an electric motor in the opposite direction to the direction of rotation of the double-twisted spindle.
  • a spinning thread is pulled up from each spinning rotor and fed to the spindle center, that is to say the hollow axis of the double-wire twisting spindle.
  • the trade association is created, which is directly followed by the first twisting zone of the double-wire twisting spindle connects.
  • the thread is then conveyed radially outwards through the usual thread guide channel and deflected upwards along the thread guide element that also rotates with the spindle rotor, wherein it is guided in the area of the fiber feed or fiber feed through the thread guide element that also rotates before it lies in the extension of the spindle hollow axis Centering point, for example a balloon thread guide eyelet, passes through.
  • this balloon thread guide eyelet is a positively driven take-off unit which is fixed to the frame and which is followed by a conventional thread winding unit. Between the take-off unit and the take-up unit, a conventional thread length compensation unit is arranged, which has a certain thread storage function.
  • the feeding or feeding of the dissolved fiber material to or into the spinning units is preferably carried out by means of negative pressure, which is built up in the area of the spinning units by a suction pipe running in the area of the spindle axis, which is connected at its outer end to a suction source, while the Connect the inner end of this suction tube to air channels which are guided so that they are able to build up a negative pressure gradient in the direction of the fiber feed, which causes the fiber feed to the spinning unit, in the fiber material feed tubes.
  • FIG. 1 shows a schematic representation of the process of the open-end spinning / twisting process according to the invention within a space of a double-wire twisting spindle enclosed by a thread balloon.
  • FIG. 2 shows, partly in section, a perspective view of a double-wire twisting spindle with an upstream fiber-dissolving unit and a downstream thread winding unit.
  • FIG. 3 shows a sectional view of a double-wire twisting spindle with integrated spinning units in the form of spinning rotors.
  • the schematic representation according to FIG. 1 shows two rotor spinning devices R1 and R2 which are arranged directly adjacent to one another and driven by a motor M, and which have fiber material dissolved in the direction of arrows f1 and f2 through fiber material supply tubes 3 and 4 and directly in the spinning rotors 1 and 2 outgoing fiber material feed pipes 5 and 6 are supplied.
  • the spun threads F1 and F2 produced within the spinning rotors 1 and 2 according to the usual open-end method are drawn upwards out of the spinning rotors 1 and 2 open at the top and brought together at a union point P, from where they form a twine in accordance with the double-wire principle F3 can be combined by axially along the axial wire in the usual way through the double-wire twisting spindle shown schematically in FIG.
  • the spindle axis is withdrawn and, after exiting the radial thread storage channel, forming a thread balloon up to the centering point defined in the extension of the spindle hollow axis, defined by the two roller bodies a and b , and from there it is carried on in the usual way to a thread winding unit.
  • the spinning rotors 1 and 2 rotate in the same direction in one direction of rotation, while the spindle rotor, not shown, of the double-wire twisting spindle in the direction of the arrow f5 opposite to the two spinning rotors circulates.
  • the thread or thread f3 is passed through a thread guide element 8 attached to the upper edge of the balloon limiter 7, which in the gap between the outer feed pipes 3, 4 and in the Spinning rotors, barrel material feed pipes 5, 6 protrude.
  • the two spinning rotors 1 and 2 of the rotor spinning devices R1 and R2 are driven by the motor M by means of a drive belt 9.
  • FIG. 2 shows an outer housing 10 which surrounds a double-wire twisting spindle, which is represented essentially by the balloon limiter 7, the upper inlet opening of the spindle hollow axis 11 and the thread travel path schematically represented by the arrows f6, f7 and f8.
  • a chamber 12 is arranged within the space defined by the balloon limiter 7, in which one (R2) of the two rotor spinning devices indicated in FIG. 1 is housed.
  • the fiber material feed pipe 6 opens into the spinning rotor 2, the outer fiber material feed opening of which lies in a cover 12.3 of the chamber 12.
  • This feed opening is at a distance from the opening of the fiber material introduction tube 4 which is guided through the outer housing 10 and which forms part of a fiber material dissolving unit 14 to which a fiber band FB is fed from a can 20 for the rotor spinning device R1 (not shown in FIG. 2) the same fiber material dissolving unit 15 is provided.
  • the two spinning threads drawn up from the spinning rotor 1 and 2 are combined with one another in the region of the upper inlet opening 11a of the hollow spindle axis 11, they pass through the hollow spindle axis in the direction of the arrow f6 downward, and are then drawn off radially outward in the direction of the arrow f7 before they are pulled off essentially upwards in the direction of arrow f8 along the inner surface of the balloon limiter 7 and are guided to a delivery mechanism 16, 17 through a thread outlet opening coaxial with the spindle hollow axis on the upper side of the outer housing 10. Behind this delivery mechanism 16, 17, the finished thread is passed on to two deflection rollers 18, 19, of which at least one is pivotably mounted against spring force to form a thread length compensation mechanism, to a conventional traverse thread winding unit B.
  • a hollow shaft 23 is rotatably mounted in a machine frame represented by a spindle bench 21 by means of a bearing block 22, whose outer, that is, the lower end, can be connected to a suction air source, not shown.
  • a balloon limiter 7 is attached to the outer circumference of the spindle rotor disk 26 as a thread guide element for the thread F3 which carries a thread guide member 28 at its upper end.
  • the spindle rotor is thus essentially formed by the following elements: hollow shaft 23, spindle rotor disk 26, balloon limiter 7, thread guide member 28 and thread guide tube 29.
  • the essentially closed, rotation-proof chamber 12 On the upper end of the hollow shaft 23, with the interposition of suitable bearings, the essentially closed, rotation-proof chamber 12 is mounted, which preferably has the shape of a cylinder and comprises a bottom 12.1, an outer wall 12.2 and a removable cover 12.3.
  • the two rotor spinning devices R1 and R2 are accommodated in this chamber 12, the spinning rotors 1 and 2 of which are driven by the motor M (not shown in FIG. 3) by means of the drive belt 9.
  • the cover 12.3 Through the cover 12.3, the fiber material feed pipes 5 and 6 shown schematically in particular in FIGS. 1 and 2 open into the spinning rotors 1 and 2.
  • thread take-off tubes 31 and 32 which run coaxially above the spinning rotor axes, through which the spinning threads F1 and F2 produced in the spinning rotors 1 and 2 are drawn off before they enter through the upper inlet end 11a of the downwardly directed hollow spindle axis 11, which, for example, interposes one Annular gap seal 33 opens into the upper end of the thread guide tube 29.
  • the hollow shaft 23 At the inner end of the hollow shaft 23 there are air channels 39, 40 which open into the interior of the chamber 12 in the area of the spinning rotors 1 and 2.
  • the outer end of the hollow shaft 23 is connected in a manner not shown to a suction source, so that a vacuum is generated in the interior of the chamber 12 via the hollow shaft 23 and the air channels 39, 40, which acts in the fiber material feed pipes 5 and 6 and fiber feed to the spinning rotors 1 and 2.
  • the spinning and twisting unit described so far in connection with FIG. 3 is surrounded by an outer housing 34 which carries a removable cover 35 into which, for example, holding magnets N are inserted, which cooperate with counter magnets S inserted in the cover 12.3 of the chamber 12 in order to achieve the To hold chamber 12 and thus the rotor spinning devices R1 and R2 as a non-contact holding device against rotation about the spindle axis.
  • the motor M is supplied with energy through the spindle rotor disk 26 via a slip ring contact system 41, 42, 43 and 44, which is indicated schematically in FIG. 3, and corresponding electrical line connections. Dynamometric energy conversion can also be used to generate and supply the necessary electrical energy.
  • the thread guide element shown in particular in FIGS. 2 and 3 in the form of a balloon limiter 7, can take the form of a thread guide tube adjoining the thread guide channel 27 and optionally guided up to the upper centering point, i.e. the thread outlet opening 37, the thread guide element shown in FIG 28 can form part of this thread guide tube.
  • the thread guide tube can also end at the level of the thread guide tube 28, with the upper end of this thread guide tube then taking over the function of the thread guide gate 28 which is otherwise present.
