Definitions

  • the invention relates to a device for spinning a winder yarn, with a pair of delivery rollers, a hollow spindle with binding thread bobbin arranged downstream of the latter, between the delivery roller pair and the hollow spindle, which housing is movable relative to the hollow spindle and has a main channel into which a fiber suction channel opens, a pair of pulling rollers and one Take-up device.
  • a device of the type mentioned is already known (GB-A-20 76 863).
  • the housing present between the pair of delivery rollers and the hollow spindle is part of a closure member which is telescopically displaceable on a housing concentrically surrounding the hollow spindle with the binding thread bobbin.
  • a device which is constructed in such a way that two suction pipes are used (DE-A-27 53 349).
  • a suction pipe can be closed via a slide.
  • a spun fiber bundle is pulled into the suction pipe to remedy a broken thread.
  • the wrapping yarn is returned to a location between the pair of delivery rollers and the hollow spindle and sucked into the other suction tube.
  • the suction air flow in the first suction pipe is interrupted with the help of a slide. Now the hollow spindle is put into operation, which has the effect that the wrapping yarn located in the second suction tube and the binding thread are withdrawn from it and thereby form a thread balloon.
  • the spun fiber bundle is released by the suction air atom, which is interrupted in the first suction pipe, and passes through an opening into the interior of a housing.
  • the bundle of spun fibers is grasped by the thread balloon formed by the binding thread and the wrapping yarn and twisted with both.
  • a housing which encloses the binding thread spool. This results in a structural and spatial effort, and access to the binding thread spool is also made more difficult.
  • the prior art also includes another device for spinning on a winding thread, the spinning after a thread break being carried out by means of a slot by inserting the thread behind the pair of output rollers (DE-A-29 30 798).
  • a thread holding device is required in the area of the pair of output rollers, a switch-on device for thread take-off also having to be used, which comes into operation when the winding spindle has reached operating speed.
  • Precautions are also required to allow the thread to enter the exit roller pair and the take-off roller pair.
  • Another disadvantage here is the high level of design and construction costs.
  • the object of the present invention is to provide a device which, with a simple and compact construction, enables reliable piecing without thereby obstructing access to the binding thread spool.
  • a closure member which can interrupt the suction effect of the fiber suction channel is movably mounted in the housing and a thread suction channel opening into the main channel is arranged behind the mouth of the fiber suction channel in the fiber running direction, and in that the housing at the lower end of the main channel has an airtight seal against the mouth of the hollow spindle.
  • the closure member can be designed, for example, as a slide, flap, screen or hose clamp.
  • the closure member came to be movably mounted in the housing at the mouth of the fiber suction channel in the main channel.
  • the closure member can be designed as a tube.
  • the tube can be rotatably mounted in the housing transversely to the main channel about its longitudinal axis and can be provided with cutouts in the wall.
  • the fiber suction channel and the main channel can be closed in the desired sense simply by rotating the tube.
  • a swirl nozzle acting in the main channel can be arranged in the housing in the fiber running direction behind the mouth of the thread suction channel. This swirl nozzle helps to improve the piecing process after a thread break.
  • the tube in the housing can be arranged axially to the main channel in this, provided in the recessed wall with covers for closing off the fiber suction channel and be rotatable about its longitudinal axis. This also results in a functional closing of the respective channels by good rotation of the tube, with good use of space.
  • the covers for the fiber suction channel can be offset by 90 ° with respect to the covers for the thread suction channel, the tube being rotatable through 90 ° about its longitudinal axis.
  • the tube in the housing can also be arranged axially to the main channel in the latter and be movable in the longitudinal direction.
  • the fiber suction channel can lead directly and the thread suction channel into a suction channel for fibers and threads via a long thread guide tube.
  • This long thread guide tube can be designed as a loop.
  • shut-off device can be designed, for example, as a slide, the slide being provided with at least one through opening and being movable into at least one open or closed position.
  • a sieve is arranged in the thread suction channel and that the slide is provided with two through openings in front of and behind the sieve.
  • a further embodiment of the invention which is particularly suitable for coarser yarns, is characterized in that the thread suction channel is arranged on the side of the main channel opposite the mouth of the fiber suction channel and that in addition a closure member designed as a slide crosswise upstream of the mouths of the fiber suction channel and the thread suction channel into the main channel is movable.
  • Another advantage is the longer, free yarn length for fiber attachment during piecing.
  • the main channel can be sealed and sealed by the slide, which advantageously increases the negative pressure on the hollow spindle and thus facilitates the suctioning of the thread end.
  • the slider can have a lip which, in the retracted position of the slider in cooperation with a wall section of the thread suction channel, narrows the cross section of this thread suction channel to a narrow passage that resiliently retains the suctioned thread.
  • the slide can consist of a slidable sleeve in a bore of the housing, the front and back of which are closed and the wall of which is directed towards the mouths of the thread suction channel and the fiber suction channel, which results in a simple construction of the closure member.
  • the slide can be spring-loaded and can be locked in the position connecting the mouths of the thread suction channel and the fiber suction channel.
  • a closure member which can be interrupted by the suction effect of the fiber suction channel can be arranged at a distance from the mouth of the fiber suction channel and has a distance from the clamping line of the pair of delivery rollers which is greater than the length of the fibers to be processed.
  • the device shown in FIG. 1 for spinning a wrapping yarn has a pair of delivery rollers 1, a downstream wrapping spindle 2 designed as a hollow spindle with a binding thread spool, a pair of take-off rollers 3 and a winding device 4. Furthermore, a tangential belt drive 8 is provided for the winding spindle 2. Between the pair of delivery rollers 1 and the hollow spindle 2, a housing 5 is arranged, the interior of which via a Connection line 6 are connected to a suction channel 7.
  • the first embodiment of the invention shown in FIGS. 2 to 5 in different process stages has a main channel 14 in a housing 5, into which a fiber suction channel 9 and behind it a thread suction channel 10 open.
  • FIG. 2 shows the normal running of the fibers 11, which are solidified into yarn by issuing false twist by the winding thread, drawn off by the pair of draw-off rollers 3 according to FIG. 1 and wound onto the spool of the winding device 4.
  • This issuing of false twist and the deflection of the fibers 11 to the thread 12 can be carried out by a pneumatic swirl nozzle 16 arranged behind (under) the mouth of the thread suction channel 10 in the main channel 14 in the fiber running direction, which is switched on simultaneously with the closing of the fiber suction channel 9 and after the thread break has been eliminated is switched off again.
  • This swirl nozzle is shown in more detail in FIGS. 11 to 14.
  • the figures of this drawing do not show the preparation of the wrapping thread, which is also usually broken: the end of the broken wrapping thread is sought on the wrapping thread bobbin of the previously shut-off hollow spindle and fastened to a stationary machine part adjacent to the winding spindle 2. If the winding spindle 2 is then put into operation shortly before the fiber suction channel 9 is closed, the winding thread winds around the thread 12 and continues this winding when the thread is drawn off on the thread formed from the newly attached fibers.
  • the fiber suction channel 9 is opened again so that in the event of a further thread breakage, the fibers which are fed in and which are no longer spun can be sucked off immediately.
  • the thread suction channel is designed as a loop 10 ′, which leads into the uniform suction channel 7 for fibers and threads, which is also directly connected to the fiber suction channel 9.
  • the loop 10 ' is so long that it can accommodate the longest piece of thread that may be sucked in without its end protruding into the suction channel 7.
  • separate suction channels 7 and 7 ' can be provided, the fiber suction channel 9 leading into the suction channel 7 and via a line 10 "the thread suction channel into the suction channel 7' for threads.
  • the fiber suction duct 9 and the thread suction duct 10 are provided with through openings 42 and 43 as well as 44 and 45. Between these through openings there is a slide 40 with the two openings 46 and 47.
  • FIG. 8 shows the normal position, in which, according to item 1 of the slide 40, the thread suction duct 10 is separated from the suction draft: the full suction draft acts on the fiber suction duct 9, in order to be able to immediately vacuum any fibers that are no longer spun in the event of a thread break.
  • Fig. 9 shows the thread suction position, with the slide 40 in position 11.
  • the slide 40 is guided all the way to the right so that a connection between the channels 9 and 10 behind the screen 41 via the passages 42, 44 and 46, which are congruent. So that the space behind the screen 41 is connected to the suction.
  • the thread is sucked in and deposited on the sieve 41, from where it is drawn off again during the actual piecing process after the trigger has been switched on.
  • position 111 according to FIG. 10 is provided, in which the slide 40, which is moved completely to the left, connects the two openings 43 and 45 to one another by means of the handle 50 via the passage opening 47.
  • the space in front of the sieve 41 is thus connected to the suction train, with fiber residues deposited on the sieve being suctioned off.
  • FIGS. 2 to 5 The embodiment of the invention shown schematically in FIGS. 2 to 5 is explained in more detail constructively in FIGS. 11, 12 and 13. It can be seen here that a housing 5 is arranged in the intermediate space between the delivery roller pair 1 and the hollow spindle, in which the main channel 14 runs. Inside the housing 5 there is also the fiber suction duct 9 and the thread suction duct 10, both of which can be connected to the main duct 14 via a pipe 15.
  • This tube 15 is rotatably supported in the housing 5 in this embodiment, transverse to the main channel 14.
  • recesses 19 and 20 and terminations 21 and 22 are provided in the wall of the tube 15. It can be seen here how the two channels 9 and 10 can be closed in a functionally correct manner via the terminations 21 and 22.
  • the representation according to FIG. 11 corresponds to the schematic representation according to FIG. 2.
  • the swirl nozzle 16 is also located in the housing 5.
  • a seal 17 is provided below the housing 5.
  • the seal 17 is provided, which, according to FIG. 12, lies airtight on the upper mouth of the hollow spindle by pivoting the housing 5 in the direction of arrow I.
  • the housing 5 is designed to be tiltable, and the housing 5 can be tilted according to FIG. 1 about the axis 30.
  • a knurled handle 18 can be provided, which cooperates with a locking device 31.
  • the covers 28 of the tube 23 for the fiber suction duct 9 are offset by 90 ° with respect to the covers 27 for the thread suction duct 10.
  • the tube 23 is rotatable by 90 ° about its longitudinal axis. 17 shows the operating state: the fiber suction is open and the thread suction is closed, 0 ° being provided as the starting position.
  • the tube 26 is arranged in the housing 5 axially to the main channel 14 and movable in the longitudinal direction 11.
  • a functionally correct locking of the tube 26 can be effected by means of a latching 25, as is also used in the exemplary embodiment according to FIG. 15.
  • the handle 33 which is connected to the tube 26, the tube 2G in the housing 5 can be axially Move main channel 14 as desired.
  • the housing 5 is designed in such a way that an opening 51 of a fiber suction channel 9 runs through soft fibers 11 on both sides of a main channel 14, which are consolidated into yarn by giving false twist by a winding thread and an opening 54 of a thread suction channel 10 are arranged.
  • a bore 55 is arranged offset by 90 °.
  • a slide 60 is mounted horizontally displaceably as a closure member in the present embodiment.
  • This slide 60 consists of a sleeve which can slide in the bore 55 of the housing 5, the front 61 and the rear 62 of which are closed. Furthermore, this sleeve has a lip 80 following the front 61. The wall 63 of the sleeve facing the mouths 51 and 54 is open.
  • the sleeve of the slide 60 is connected to a rotary handle 70 via a pin 64.
  • the bore 55 is closed at the rear end by a plate 71 through which the pin 64 of the slide 60 passes.
  • the plate 71 has a continuous threaded hole 68.
  • a thread 74 on the pin 64 is a thread 74 on the pin 64.
  • FIG. 21 shows the normal running of the fibers 11, which are solidified to give yarn by giving false twist by the wrapping thread, drawn off by the draw-off roller pair 3 according to FIG. 1 and wound onto the spool of the winding device 4. If a thread break occurs now, with the hollow spindle 2 shut down, the individual fibers which have been supplied and are no longer solidified by rotation are sucked into the fiber suction channel 9 by the suction. The fiber feed is then interrupted by the pair of delivery rollers 1 into the piecing device and the fiber suction channel 9 is closed. 22 is closed by a closure device shown in FIG. 22 via a closure member 85, which is advantageously attached to the piecing device at a distance which is greater than the maximum fiber length of the fibers to be processed.
  • the end of a broken thread is returned to the suction area of the thread suction channel 9 and sucked into the channel.
  • the slide 60 is pushed to the right into the position shown in FIG. 22 by pressing the rotary handle 70 and the rotary handle 70 is rotated, as a result of which, due to the interaction of the thread 74 with the threaded hole 68 of the plate 71, a locking in the in FIG. 22 shown location is achieved.
  • the front side 61 bears against the end face of the mouth 51, so that the main channel 14 is sealed to increase the negative pressure on the hollow spindle 2.
  • the slide 60 After completion of the suction process, the slide 60 is returned to the starting position shown in FIG. 21. In this starting position, the slide 60 fulfills a further function in that, by means of the force of the spring 65, it clamps the thread in a controlled manner in the gap between the lip 80 of the slide 60 and the wall section 81 of the thread suction channel 10, so that it later emerges from the thread suction channel in a taut state 10 is pulled out.
  • the fiber suction channel 9 is now opened again and the feeding of the fibers 11 into the piecing device is resumed, the fibers being sucked into the fiber suction channel 9 after they have left the pair of delivery rollers.
  • the last phase of the piecing process is initiated in that the hollow spindle 2 is put into operation by pressing the tangential belt 8 and the fiber suction channel 9 is closed again. Simultaneously with the completion of the fiber suction channel 9, the withdrawal of the thread is taken up again by the pair of withdrawal rollers 3, so that the fibers 11 lying against the thread are integrated into the thread and drawn off with it - a process which continues and for the continuous formation of one Thread leads.
  • the piecing process of a wrapping thread can also be carried out for coarse threads.
  • the suction effect is so great that these coarse yarns, for example made of bristly carpet fibers, can also be sucked in.
  • the end of the broken yarn or thread can be brought close to the nip line of the pair of delivery rollers and thus a good connection of the fibers with the thread can be achieved. Trouble-free suction of the staple fibers with the thread end already inserted in the thread suction channel is nevertheless ensured.
  • a retention force acts on the sucked-in thread end, so that the thread is pulled out of the thread suction channel 10 tightly and without loops during the piecing process.
