Definitions

  • the invention relates to a drafting system for spinning machines with a fiber bundling zone, which joins the pair of output rollers of the drafting system and which is limited by the delivery rollers pair to the spinning zone, a pneumatic compression arrangement being provided in the fiber bundling zone, which consists of an endless along a circumferential line per spinning station There is perforated straps, which is guided around the lower delivery roller and at least one further guide, which forms a strand that extends from the clamping line of the pair of delivery rollers in the direction of the pair of exit rollers and to which a suction shoe is assigned on the inside of this strand, which guides for the perforated strap near the pair of exit rollers.
  • the invention also relates to a ring spinning machine with drafting systems, with compression zones, with cleaning arrangements and central suction channels.
  • a so-called compression drafting device of the type described above is known from DE 10 39 422. Following the high draft zone of the drafting system, a pneumatic fiber bundling zone is arranged, which is limited to the spinning zone by a pair of delivery rollers. About the lower delivery roller a centrally perforated strap led, which has a second guide immediately in front of the exit rollers of the drafting system.
  • a suction arrangement is provided below the upper run of this perforated strap, which generates a suction air flow through the perforation of the strap.
  • This suction air flow collects the fibers of the fuse in front of the upper openings of the perforation and thereby reduces the width of the fuse. This is fed into the spinning zone in the narrow form, clamped by the delivery rollers.
  • the suction arrangement is located above the lower run of the perforated apron and is attached to the loading arm of the drafting system, which guides, loads and can lift all the top rollers.
  • the suction line must therefore either be interrupted when swiveling out or be flexible. This arrangement has several very important disadvantages. If the load arm with the top rollers and the suction arrangement is raised for the purpose of eliminating a thread break, the suction air must be switched off. The suction shoe with the compressed air connection and the upper delivery roller is swiveled upwards.
  • Another problem is that the lower delivery roller is moving at its circumference at the given speed.
  • the apron which has to move the upper loaded delivery roller and is also braked to a considerable extent by the frictional guidance around an acute-angled leading edge, moves at a lower speed.
  • the fibers of the fiber bundle are warped in the area of the clamping gap and cannot be compensated for until the beginning of the spinning process.
  • DE 11 78 749 has proposed assigning the compression perforation with the suction arrangement to the lower output roller of the drafting system. This measure did not lead to the desired result because the fibers should be collected precisely in the area where the greatest clamping forces and distortion forces are exerted on the fibers. The goal of collecting the fibers in a very narrow area was also not eliminated by additional measures, such as the provision of air guiding channels on the surface of the rollers. Attempts have also been made to avoid the perforated straps to be arranged on the loading arm by perforating the upper delivery roller along a circumferential line and positioning a suction arrangement in its interior (DE 41 39 067 C2).
  • the lower apron for guiding these fibers was also passed over the lower delivery roller and over the lower exit roller. Both lower rollers are driven rollers. Maintaining and changing this lower apron presents the same difficulties as described above.
  • the sieve roller which is hollow and has a large number of bores, requires complicated and expensive measures to store and drive the same. It also poses considerable problems to generate a precisely defined suction air flow in the area of each spinning station.
  • Another disadvantage is the lateral compression of the fiber strand by the profiles sliding on the sieve drum. Fibers jam on the sliding edges. As soon as one of the fibers gets stuck there, this leads to a chain reaction, which leads to the breakage of the fiber strand.
  • This device is therefore not suitable for use on highly productive spinning machines.
  • the object of the present invention is to provide a reliable method of operation on ring spinning machines with a large number of closely adjacent spinning positions, with high draft drafting systems and with compression zones which are arranged downstream of the drafting system and which each have a pair of delivery rollers and straps which are perforated along a circumferential line and to ensure easy operation and maintenance of the spinning stations.
  • a high degree of fiber bundling should be achieved on the nip line of the delivery rollers.
  • This device should also be simple in construction and inexpensive to manufacture, operate and maintain.
  • a further object of the present invention is to propose a ring spinning machine with drafting devices, compressor zones and pneumatic cleaning arrangements, as well as with at least one central suction channel and filter, in which the negative pressure in the compression zones with a reasonable suction power is of a sufficient size in which the cross sections of the suction lines are optimal can be designed and the monitoring by the operating personnel can be simplified.
  • the first part of the task is solved in a simple manner by the new features defined in claim 1.
  • the fibers of the loose fiber strand are reliably taken over by the tear-off rollers and securely bundled in the perforation area over a sufficiently long running distance and fed as a narrow strand to the nip roller nip of the delivery rollers.
  • the loading arm can be raised in the usual way without first switching off the suction air. After the thread break has been eliminated, the spinning process can be started again without any additional steps.
  • Discarding the fibers of the fiber strand is excluded. The remaining minimal remainder can be compensated for in a manner known per se by a small tensioning delay between the output rollers and the delivery rollers.
  • the design of the drive of the delivery roller according to claim 3 avoids expensive gears for the transmission of the drive movement to the delivery rollers.
  • a drive shaft according to claim 4 has the advantage that the drive of this shaft - in a conventional manner - can be derived from the drafting system drive and that the drive movement at all spinning positions or pairs of spinning positions can be easily transmitted to the lower delivery roller.
  • Claims 5 to 7 show optimized designs of the drive of the lower delivery roller under the conditions of simple manufacture and reliable power transmission.
  • the previously defined requirements make it possible to change the perforated straps of every work station in just a few simple steps. Time-consuming assembly work is no longer necessary.
  • the design and arrangement of the suction shoe according to claim 8 enables easy removal of the suction shoe for the purpose of cleaning and maintenance.
  • the additional guide for the perforated straps in front of the lower delivery roller ensures on the one hand a more reliable detachment of the fibers from the strappy surface.
  • the brief lifting of the strap after the clamping point prevents the parts of fibers which have been drawn in through the perforation holes and which are temporarily clamped between the surface of the lower delivery roller and the inner surface of the strap, in the area of the spinning position be released again.
  • Claim 12 ensures easy maintenance of the suction shoes.
  • the use of two central suction channels with different vacuum levels makes it possible, in particular, to set the vacuum in the compression zone to an optimal level necessary there, without simultaneously changing the suction conditions of the cleaning arrangement.
  • the suction pipes between the suction openings of the cleaning arrangements and the central suction channel can be designed with a sufficiently large, optimized cross section. The risk of the suction lines becoming clogged is reduced. The monitoring effort is reduced. The power requirement for the suction compressor is reduced.

  • the draft is essentially ended on this pair of rollers 14.
  • the lower rollers of this drafting arrangement are driven rollers. They receive their rotary movement from a corresponding gear (not shown).
  • the respective upper rollers are carried along by the frictional contact with the respective lower rollers. They have their bearing on the pivotable loading arm 15. This loading arm 15 can be pivoted upwards around the bearing for the purpose of operating the drafting system with the upper rollers.
  • a funnel-shaped sliver guide 13 is positioned in front of the nip of the pair of drafting rollers 12 to ensure that the fiber sliver runs as narrowly as possible into the area of greatest draft.
  • the compression zone follows. It is limited to the spinning zone by the pair of delivery rollers 2.
  • the compression zone has the task of laterally bringing together the fibers that leave the pair of output rollers 14 in a relatively wide band in such a way that the fiber assembly that reaches the pair of delivery rollers 2 and leaves at the nip thereof becomes very narrow, so that the so-called spinning triangle, the the position of the fibers and their integration in the thread is largely determined, is very small.
  • a perforated strap 4 is guided over the lower delivery roller 21.
  • the perforation 41 is only on a single circumferential line.
  • the size of the holes in this perforation 41 depends on the desired size of the spinning triangle.
  • the strap 4 continues to wrap around the immediately adjacent suction shoe 6, which is simultaneously equipped with a guide edge 62 and contains a narrow suction opening 61 which is aligned parallel to the perforation 41.
  • the suction opening 61 extends from the area of the pair of output rollers 14 to the gusset of the pair of delivery rollers 2.
  • the strap 4 is additionally passed over a guide 32.
  • the lower delivery roller 21 is fastened to a support body 3 which can be moved to a limited extent about a pivot bearing 31.
  • the upper delivery roller 22 bears against the top of the apron 4. It is non-positively driven by the strappy 4.
  • the lower delivery roller 21 is driven laterally next to the apron 4 by the drive roller 5 which is fixed to the frame and driven by the drafting gear mechanism.
  • the drive rollers 5 of all spinning positions of a spinning machine are located on a drive shaft 50.

  • One of these surfaces 212, 53, 53 ' is preferably formed as a roughened steel surface and the opposite surface as an elastic ring (z. B. 23).

  • a relative movement between fibers and straps 4 in the direction of movement of straps 4 does not take place in principle.
  • the fibers thus combined reach the nip of the delivery rollers 21, 22 and are held there and released to the spinning zone. There the spinning process begins at the tip of a very small spinning triangle.
  • the entire section of the apron 4 following the clamping gap and located below the guide 32 is largely loose up to the guide edge 62. This loose section slides almost without tension onto the guide section 62, so that the rope friction occurring there in the upper run of the strap 4 can be kept very small.
