Definitions

  • the invention relates to a method and an apparatus for spinning with suppressed Thread balloon, the rotation of the thread predominantly between a spindle attachment and the nip of delivery rollers at the exit of the Drafting system is generated, with the spindle attachment in its head area is provided with one or more projections and with these projections on the extended axis of the spindle from below to one extends vertically adjustable thread guide, and being used to prepare a automated bobbin change the vertically adjustable thread guide from the spindle attachment moved upwards and the ring bench then in the downwind position is lowered.
  • the thread balloon is suppressed and the thread can be reduced Voltage can be wound on the coil. There are also advantages regarding the running properties of the runner.
  • spinning was therefore preferred Yarns, especially fine carded or worsted yarns, mainly spinning with a reduced thread balloon using so-called balloon limiting rings.
  • the increase in speed and thus the increase in performance the spinning machine is limited.
  • the object of the present invention is to propose a spinning process with a spinning head and suppressed thread balloon, which allows very fine and smooth threads to be produced with high reliability at high spindle speeds and with automated spool change.
  • the object of the invention is also a device for reliable implementation propose the process with the least design effort also the phases between the normal spinning process and the spool change can perform in an optimal way.
  • the parameters according to claim 3 contribute to the further optimization of this process when stopping before changing bobbins.
  • Claim 4 defines the details of the process steps when restarting the spinning machine after changing the bobbin.
  • Claim 5 recommends the defined procedural steps for a stopping and Start-up program in which no bobbin change is provided.
  • the device according to claim 6 allows the optimal execution of the method according to claim 1 and also ensures high reliability the compression process under the conditions of balloon-reduced spinning.
  • the exact setting of the distance between the thread guide and the spinning head is the prerequisite for the use of spinning heads with a very small cross-section.
  • the sleeves can also be relatively low and narrow Spinning heads are moved without the latter for the execution of the Coil change must decrease.
  • the design effort is kept low.
  • the time required for changing the bobbin is reduced.
  • the ring spinning machine has a large number of spindles 1 in the usual way.
  • So-called spindle attachments 2 are attached to these spindles 1 at the top. In the example chosen, it is a so-called spinning finger. It is also possible to provide a corresponding spinning crown in its place (see, for example, DE 26 53 697 C2). These spindle attachments 2 are inserted into a corresponding bore of the spindle 1 under prestress. These spindle attachments 2 are only changed for the purpose of maintenance.
  • the cross sections of these spindle attachments 2 are designed so that the sleeve 12 or the coil 13 can be lifted out above them. Parallel to the axis of the spindles 1, the ring bench 4 is arranged in the usual sense to be raised and lowered.
  • the ring bank 4 carries for each spindle 1 a spinning ring 41 on which the ring traveler 42 is guided in a sliding manner.
  • the ring traveler 42 deposits the thread fed into the balloon 75 on the surface of the bobbin 13.
  • the thread guide 3 is arranged directly above the spindle attachment 2 during main spinning.
  • This thread guide 3 is attached to a swivel arm 31 which is fixedly connected to the shaft 32.
  • the shaft 32 is pivotally guided on a lifting slide 33.
  • a slide guide 331 fixed to the frame is assigned to the lifting slide 33. This slide guide 331 is aligned parallel to the axis of the spindles 1.
  • the lifting slide 33 is driven in a vertically movable manner by spindles 341.
  • the spindle 341 is rotated by the motor 34, which receives its control program from a central machine control.
  • This motor 34 is suitable for moving the lifting carriage 33 with the thread guide 3 from the position 3 exactly by the stroke size or the distance 35 into the position 3 'and back.
  • the drafting unit 5 of the ring spinning machine is provided with a compression arrangement in the present case.
  • This compacting arrangement is immediately downstream of the pair of output rollers 51 of the drafting unit 5.
  • a strap 61 perforated along a central line encompasses a suction shoe 62 and the lower delivery roller 521.
  • the lower delivery roller 521 which supports the apron 61 from the inside, receives its drive from a separate drive roller 53, which generally extends over the entire length of the machine.
  • the upper delivery roller 522 lies non-positively on the perforated strap and, together with this strap, forms the clamping gap 523.
  • the operation of this compression arrangement is described in detail in an older, not previously published patent application DE 197 08 410.9.
  • suction shoe 62 is connected to a central suction channel 64 via a suction pipe 63.
  • the pressure in this system (62, 63, 64) can be designed independently of the negative pressure which is generated in the suction channel 55 and which is used for cleaning certain zones in the area of the spinning machine (e.g. suction tube 54).
  • the fully drawn fuse 71 is conveyed through the nip 511 of the pair of output rollers 51 into the compression zone (FIG. 2).
  • the suction fibers 62 collect and fix the individual fibers of the fuse over the holes in the perforation of the strap 61 as stretched and compressed fuse 72.
  • the fuse 72 thus compressed arrives in the nip 523 of the delivery rollers 521, 522.
  • the turns made in the thread due to the mode of action of the spindle attachment 2 in connection with the thread guide 3 also reach the clamping gap 523 via the thread section 73.
  • the fibers of the compressed fuse 72 are twisted directly at the clamping gap 523 - almost without the dreaded spinning triangle - in such a way that all fibers are held firmly against one another.
  • the thread is practically completely finished at the exit of the clamping gap 523 and has the predetermined, or at least the high strength necessary there.
  • the thread - the thread piece 74 - is guided in at least one turn around the spindle attachment 2, around the upper part of the spindle 1 and possibly around the upper part of the sleeve 12. Relatively close to the plane of movement of the ring traveler 42, this piece of thread 74 leaves the surface of the sleeve 12 or spindle 1 and forms a small thread balloon 75.
  • This relatively small thread balloon 75 is only subject to low air resistance and low centrifugal force.
  • the thread tension is correspondingly low there and thus also in the thread section 73.
  • These optimal spinning conditions are regularly guaranteed during the normal spinning process (here referred to as main spinning).
  • the load on the thread is low.
  • a thread is created which has a high uniformity and a high strength.
  • the hairiness of the thread is very low, in particular due to the use of the compression arrangement.
  • the spindle attachment 2, here designed as a spinning finger is practically no longer able to brush fibers out of the solid fiber composite of the thread, which then negatively influence the quality of the thread.
  • a first step the speed of spindle 1 is significantly reduced - for example to a value between 2,000 and 6,000 rpm. If this low spindle speed is reached, the thread guide 3 is moved upwards by approximately 30 to 50 mm parallel to the axis of the spindle 1 by means of a corresponding control command to the motor 34.
  • the thread delivered simultaneously by the delivery rollers 521 and 522 thereby forms a balloon immediately below the raised thread guide 3 ', which lifts out of the projections of the spindle attachment 2. Due to the action of the ring traveler 42, the turns of the thread section 74 which are still present for a short time around the spindle attachment 2 and the sleeve 12 are wound onto the bobbin 13.
  • the spinning machine now works according to the usual method of spinning with thread balloon 75 '(FIG. 4). Once the thread balloon 75 'has formed properly, the ring rail 4 can move into the downwind position (FIG. 5) in the usual way. All processes take place as is usual on spinning machines that work with thread balloons.
  • the above-mentioned reduced spindle speed should be chosen so that the diameter of the thread balloon 75 'or 75 "that is created is as small as possible than the lateral distance between two balloon separating plates 43 which are arranged between adjacent spindles 1.
  • the thread guide 3 is pivoted upwards.
  • the thread 76 is tensioned between the thread guide 3 and the ring traveler 42 when the spinning machine is at a standstill so that it does not hinder the exchange of the bobbin 13 against a new sleeve 12.
  • the thread guide 3 is first pivoted back into its upper working position approximately at a distance 35 above the spindle attachment 2 (FIG. 6).
  • the spindle 1 begins its movement at a relatively low speed.
  • the resulting thread balloon 75 "is also so small in diameter that it can move between the balloon separating plates 43 with as little collision as possible.
  • the ring rail 4 moves to the height of the lower bobbin edge and begins to wind the bobbin attachment 131.
  • the thread guide 3 is moved again by the distance 35 in the direction of the bobbin attachment 2.
  • the spinning process begins again with the suppressed thread balloon 75 (FIG. 7).
  • the thread section 74 gripped by the spindle attachment 2 now winds one or more times around the shaft of the spindle attachment 2 and around the upper section of the sleeve 12.
  • the relatively small thread tension in the thread balloon 75 is only transferred to a small extent into the thread section 73
  • the spinning process can be continued with optimal conditions.
  • the advantage of the described method is that optimal conditions for the thread to be spun are effective in all phases during the normal spinning process and while the machine is running and starting.
  • optimal conditions for the thread to be spun are effective in all phases during the normal spinning process and while the machine is running and starting.
  • this combination leads to the fact that all fibers are already twisted with one another directly at the exit of the clamping gap 523 between the perforated strap 61 and the upper delivery roller 522.
  • the number of thread breaks in this critical area is reduced at the usual speeds of the spindles 1. Assuming the usual number of thread breaks as given, you can increase the speed of the spindle during main spinning in substantial orders of magnitude.
