Definitions

  • the invention relates to a compressor unit for a drafting system of a textile machine, comprising at least one compression channel for a finished warped fiber structure, wherein the compressor unit has a holder and two fiber strand guides, in the longitudinal direction of the fiber strand can run, wherein the fiber strand guides are arranged on the holder they are spaced apart in the longitudinal direction of the fiber composite guides and wherein a first fiber strand guide at least one guide surface for the fiber structure and the second fiber strand guide comprises a compression channel for the fiber structure, and at least one of the fiber strand guides having a support surface for a drafting roller.
  • the printing roll unit has a base body and two non-contacting pressure roller twins received in the base body.
  • the printing roll unit further has a compressor unit, which is attached to a holder.
  • the compressor unit is arranged freely movable on the base body.
  • wear-resistant components are attached, which serves on the one hand for a suitable Auflagerung the compressor unit on a drafting roller and on the other hand is provided for compressing a supplied from a previously arranged drafting fiber Association.
  • the compressor unit has two wear-resistant components which come into contact with the fiber structure.
  • the first wear-resistant component is used for guiding and for easy compression of the fiber structure.
  • the second wear-resistant component has a compression channel, which compacts the fiber structure strongly and thus to improve the im Connection to the compressor unit following spinning of the fiber strand to a yarn is used.
  • the EP 3 073 000 A1 discloses a compressor unit in which the first wear-resistant component is not seated directly on the drafting roller. As a result, an adjustment of the wear-resistant component to the drafting roller is not directly required, whereby a more cost-effective production of the entire compressor unit is possible.
  • the support surface for the drafting roller in the area of the first fiber strand guide is made of a less wear-resistant material. This less wear-resistant material, which may be plastic, for example, is capable of adapting to the existing metal drafting roller through a targeted wear. As a result, a very dense contact surface with respect to the drafting roller is achieved after a short operating time.
  • the second wear-resistant component is made of steel or ceramic. and must be made very accurately to allow an exact adaptation to the drafting roller.
  • a disadvantage of the known compressor units is that the wear-resistant components sit with their wear-resistant surfaces on the drafting roller or heavily wear their holders. It is therefore necessary that a very accurate production of the two wear-resistant components must be made to ensure that both bearing surfaces, which are generally curved according to the scope of the drafting roller, flush with the drafting roller. If necessary, they must be adjusted and adjusted to ensure that there is no impermissibly large gap between the wear-resistant components and the drafting roller in which fibers of the fiber structure could penetrate. If the overlay is made of a wear-resistant material, there is a risk that the adaptation of the component to the drafting roller will not be optimal at the beginning of the use of the compressor unit.
  • Object of the present invention is thus to provide a compressor unit, which is inexpensive to manufacture and moreover to effect the compression of a located on a drafting roller and guided by the compressor unit and compacted fiber structure error-free.
  • a compressor unit according to the invention for a drafting system of a textile machine has at least one compression channel for a finished distorted fiber structure.
  • the compactor unit comprises a holder and two fiber strand guides, in the longitudinal direction of which the fiber strand can pass, wherein the fiber strand guides are arranged on the holder so as to be spaced apart in the longitudinal direction of the fiber strand guides.
  • a first fiber strand guide has at least one guide surface for the fiber strand and the second fiber strand guide has a compression channel for the fiber strand.
  • At least one of the fiber strand guides has a bearing surface for a drafting roller. The first fiber strand guide guides the fiber structure onto the drafting roller and feeds it to the subsequent second fiber strand guide.
  • the second fiber composite guide with its compression channel compacts the fiber structure, usually characterized in that the fiber assembly is compactly compacted by being deflected laterally and is thereby pressed against a side wall of the compression channel.
  • a very high-quality yarn for example by means of a ring spinning spindle, can subsequently be produced.
  • the support surface of the fiber strand guide is made of a plastic having sliding bearing properties.
  • the plastic is thus wear-resistant in contact with the drafting rollers made of steel.
  • this plastic has a low frictional resistance in conjunction with steel, whereby the operation of the drafting with the compressor unit according to the invention can be done very energy efficient.
  • the processing of the plastic to bring it into the desired shape, moreover, is also much easier than compared to the ceramic solution of the prior art.
  • the fiber composite guides are arranged on the holder and thereby press the fiber structure from above on the drafting roller or compress it between the fiber strand guide and the drafting roller. The result is a narrow opening between the first fiber strand guide and the drafting roller through which passes through the fiber structure and undergoes a first compaction.
  • the second, much stronger compaction is applied to the fiber strand through the second fiber strand guide, which has a compression channel in which the fiber strand is compressed much more.
  • the compressor unit Contains the plastic in a preferred embodiment, a solid lubricant, the compressor unit is suitable for a very long service life.
  • the sliding properties of the plastic are therefore particularly good.
  • the support surface for the support on the drafting roller on a curvature on a curvature.
  • the curvature allows a defined position of the compressor unit with respect to the drafting roller.
  • the position of the compressor unit is defined particularly precisely.
  • the storage of the compressor unit is thus particularly well and permanently possible.
  • the plastic has a resistance to an operating temperature of over 200 ° C, in particular at least 230 ° C, so he also resists the highest requirements of the compressor unit. Even with a long service life It is to be expected that no higher temperature will occur at the storage, which could damage the plastic.
  • the guide for the fiber structure and the bearing surface for the drafting roller in the area of the first fiber strand guide are produced integrally with the compressor unit, then a very cost-effective component is created which is highly suitable for compacting the fiber sliver.
  • At least one of the fiber strand guides has a wear-resistant component made of steel or ceramic for guiding the fiber structure.
  • Steel or ceramic in particular have a particularly high resistance to wear compared to the fiber structure, so that overall a particularly durable component is created.
  • the guide surface of the wear-resistant component is a wear-resistant pin which can press on the fiber structure to guide the fiber structure and has no contact with the drafting roller, then it is not necessary for this wear-resistant component to be assigned exactly to the drafting roller with respect to its circumference.
  • the compactor unit can advantageously be arranged on a pressure arm provided for two draw frames.
  • the compressor unit thus has in each case two first and second fiber strand guides for two parallel fiber bundles.
  • the compressor unit at least one receptacle for a loading element for generating a bearing force on the bearing surfaces, the compressor unit is pressed sufficiently firmly against the drafting roller, so that no gap arises in which individual fibers of the fiber structure could be drawn.
  • the compressor unit has a wear indicator for the contact surface of the fiber strand guide.
  • the wear indicator serves to detect when the wear of the support surface is so strong that proper guidance of the fiber structure can no longer be reliably ensured. Therefore, if, for example, it is flush with the wear indicator or even protrudes into the wear indicator, the operator of the machine can see that the compressor unit needs to be replaced.
  • an insertion bevel for the fiber structure is arranged on at least one of the contact surfaces of the fiber strand guides, the piecing or introduction of the fiber strand into the compressor unit is facilitated.
  • the fiber structure can be applied for example laterally between the drafting roller and the compressor unit and moved in the direction transverse to the run of the fiber structure under the compressor unit. The fiber structure is thereby introduced quickly and reliably into the guide or the compression channel by means of the insertion bevel.
  • an overflow protection for the fiber structure is arranged on at least one of the fiber structure guides.
  • the overflow protection is, for example, above the fiber strand guides, that is arranged on the side facing away from the support surface of the compressor unit. This overflow protection ensures that the fiber structure can not reach completely or partially above the fiber structure guides. Individual fibers are stopped at the overflow protection, are ideally returned to the guide or the compression channel and in any case do not pull out the entire fiber structure from the guide or the compression channel.
  • An inlet slope, in particular an inlet radius, for the fiber structure, which is arranged on at least one of the fiber strand guides, advantageously serves for better piecing or insertion of the fiber structure into the compressor unit in its longitudinal direction or running direction of the fiber structure. The inlet slope is arranged at the inlet-side edge of the fiber strand guides, which faces the drafting roller.
  • FIG. 1 shows a side view of a compressor unit 1, which is arranged over a drafting roller 2.
  • the compressor unit 1 has a first fiber strand guide 3 and a second fiber strand guide 4.

  • the first fiber strand guide 3 and the second fiber strand guide 4 are connected to each other by means of a holder 8.
  • the two fiber composite guides 3 and 4 are fixedly arranged on the holder 8 and can not move relative to the holder 8.
  • a receptacle 9 is arranged, which cooperates with a loading element 10, which supports the compressor unit 1 relative to the pressure arm 7 movable and thus causes a precise and firm pressing the compressor unit 1 on the drafting roller 2.
  • a guide 11 is arranged, which easily summarizes the fiber structure 6 and pushes it to the drafting roller 2.
  • the second fiber strand guide 4 serves to densify the fiber structure 6 and accordingly has a compression channel 13.
  • the second fiber composite guide 4 has, in addition to the compression channel 13, a bearing surface 15, which is formed substantially corresponding to the rounding of the drafting roller 2 and thus preferably rests satisfactorily on the drafting roller 2.
  • the first fiber strand guide 3 has a support surface 16 for resting on the drafting roller 2. Both bearing surfaces 15 and 16 have a curvature, so that they can adapt to the drafting roller 2.
  • the two fiber composite guides 3 and 4 are made in one piece with the holder 8 and preferably also the receptacle 9 made of plastic.
  • the receptacle 9 is used to attach the holder 8 to the loading element 10.
  • the plastic is particularly good sliding.
  • the bearing surfaces 15 and 16 of the fiber strand guide 3, 4 are made of a plastic having sliding bearing properties. These plastics, which are commonly used for sliding bearings, have a particularly good resistance to wear and a low sliding friction resistance in connection with steel from which the drafting roller 2 is made. If the plastic contains a solid lubricant, a long service life is possible. If the plastic has a resistance to an operating temperature of more than 200 ° C., in particular at least 230 ° C., then use under extreme conditions is also possible.

  • the pin 12 is fixed in the fiber strand guide 3. It consists for example of steel or ceramic, is wear resistant to the along sliding bevels and sits in a recess of the existing plastic fiber strand guide 3. The first fiber strand guide 3 thus compresses the fiber structure 6 between this pin 12 and the drafting roller. 2

  • a first compression of the fiber structure 6 takes place in the first fiber strand guide 3 with the guide 11 and the drafting roller 2.
  • this passes into the compression channel 13 of the second fiber strand guide 4.
  • the already precompressed fiber structure 6 is pressed against at least one side wall of the obliquely to the direction of the fiber structure 6 compression channel 13 and further compacted. This results in a particularly advantageous, dense fiber structure 6, which can then be spun.

  • a pin 12 is arranged.
  • the pin 12 is inserted in a receptacle which is formed as a recess.
  • the pin 12 forms the upper side of the guide 11, which is open to the support surface 16.

  • This fiber strand guide 3 is constructed similarly to the embodiment according to FIG. 4a but has no steel or ceramic pin 12. For normal applications with a less aggressive fiber material, this design, in particular because of the plastic, which is also used for plain bearings, sufficient.
  • FIG. 5a shows a section through a second fiber strand guide 4.
  • the holder 8 and the second fiber strand guide 4 are made of the same plastic.
  • the bearing surface 15 and the compression channel 13 are an integral part of the holder 8.

  • FIG. 6a shows a view from below of another compressor unit 1 for two fiber composites 6.
  • the compressor unit 1 has a wear indicator 20 for the bearing surfaces 15 and 16 of the fiber strand guides 3 and 4.
  • the wear indicator 20 is designed as an area between the two fiber strand guides 3 and 4 in the region of the holder 8. If the bearing surfaces 15 and 16 are worn after prolonged use, in which they rest on the rotating drafting roller 2, the compressor unit 1 in the radial direction of the drafting roller 2 is shortened. As a result, the radial distance between bearing surfaces 15 and 16 and the wear indicator 20 is shortened or even completely used up. In extreme cases, even material is removed from the wear indicator 20. This is the sign for an operator that the compressor unit 1 must be replaced, since the guidance of the fiber structure 6 can no longer be sufficiently ensured.
  • an insertion bevel 21 for the fiber structure 6.
  • the respective insertion bevel 21 is arranged on the outside of the fiber strand guide 4 in order to be able to apply the fiber structure 6 from the outside to the compressor unit 1 and to be able to introduce it into the guide 11 or into the compression channel 13.

  • FIG. 6b shows a side view of the compressor unit 1 of FIG. 6a ,
  • the wear indicator 20, the insertion bevel 21, the overflow guard 22 and the inlet radius 23 can be clearly seen again.
  • the guide 11 has a support surface 16 which has a rounding on only one side, which rests on the drafting roller 2.
  • the other side, in particular the outer side, is shortened, so that while still a guide of the fiber structure 6 can be done, but on the other hand, the lateral insertion of the fiber structure 6 is easy to do.
  • the present invention is not limited to the illustrated and described embodiments. Variations within the scope of the claims are also possible as a combination of features, even if they are shown and described in different embodiments.
