Definitions

  • the invention relates to a compressor for a drafting system of a spinning machine, for arrangement between a delivery cylinder and an output pressure roller, with a tapered to a delivery pressure roller of the drafting direction tapered first compressor passage.
  • a compressor according to claim 1 namely a compressor for a drafting system of a spinning machine, for arrangement between a Delivery cylinder and an output pressure roller, with a to a delivery pressure roller of the drafting out oriented tapered first compressor passage, characterized in that the compressor has a second compressor passage, which, viewed in the direction of a stretched sliver, before the first compressor and is arranged in alignment therewith.
  • This design and arrangement of the compressor according to the invention has many advantages.
  • the yarn values are substantially improved, as will be apparent from the following.
  • a stretched sliver running through the second compressor channel during operation of the drafting system is already precompressed by it.
  • the second compressor channel serves as a tunnel between the cage straps of the drafting system and the clamping point of the output pressure roller. It should be prevented so that as possible no fibers are lost on this route.
  • the acting as a supercharger second compressor passage guarantees the inlet of the stretched sliver in direct alignment in the compressor, since the sliver by the first contact with the second compressor channel determines the position of the compressor, which has axial clearance, and not vice versa, as in the prior art, where the axially fixed compressor forces the sliver. It can affect the incoming into the compressor sliver the horizontal position of the compressor, which rests freely movable on the lower cylinder, or is held only by magnets and output pressure roller and delivery pressure roller.
  • both the second and the first compressor duct belong to one and the same compressor and are arranged in alignment with one another, the first compressor is possibly also moved together with the second compressor.
  • the stretched sliver is thus advantageously always guided by the orientation by means of the second compressor passage directly to the first compressor passage and into it.
  • the compressor is at the reference of the delivery roller, whereby a minimum possible distance from the compressor outlet, this corresponds to the rear end of the first compressor channel, is ensured to the terminal point of the delivery roller, so that the compression can not or only very slightly dissolve again and Thus, the desired yarn values (especially hairiness and strength) remain constant and yarn breaks can be minimized.
  • the invention has particular significance in the processing of long staple fibers, e.g. B. wool. Wool fibers are stiffer than cotton. They run in devices of the prior art therefore in doubt not through the first compressor duct, but past him. Exactly this circumstance is due to the invention possible floating arrangement of the compressor according to the invention and the connection of the second compressor duct with the first compressor duct encountered. The comparatively very long long staple fiber usually forms a relatively wide roving. The spinning triangle is therefore correspondingly succinct. Due to the construction of the compressor according to the invention can be ensured that all possible fibers enter the compressor, as described above.
  • the compressor according to the invention can be formed symmetrically or asymmetrically.
  • the compressor is characterized in that the second compressor duct has a larger cross section than the first compressor duct.
  • the compressor is characterized in that both compressor channels taper as seen in the direction of the stretched sliver. Not only the first compressor channel tapers as usual to the optimum dimension up to the top of the spinning triangle. Even the second compressor channel tapers to gently pre-compact the stretched sliver.
  • the compressor is characterized in that it has a head adjoining a neck extending between the top roller and the delivery roller, which extends so far towards the running surface of the output pressure roller and the delivery pressure roller its extension is wider than the gap between the outlet pressure roller and delivery pressure roller.
  • the compressor is characterized in that it comprises at least one, preferably releasably, mounted therein magnets. This training advantageously contributes to a safer and better balanced positioning of the compressor on the delivery cylinder.
  • the compressor is characterized in that it is formed from low-wear sprayable plastic.
  • This inventive design and arrangement of the compressor has many advantages. It is proposed an elastic securing element, which may consist of relatively cheap and injectable plastic, in which magnets can be releasably engaged or glued.
  • the compressor is characterized in that it has a device for fixing colored markings.
  • markings may be pins or plugs or the like in different colors, which are clipped, for example, in devices such as cavities of the compressor, with the effect that it can already be seen from a distance which compressor for which sub cylinder diameter and with which size of the first compressor duct etc . is equipped.
  • Fig. 1a 2 shows essential parts of an exemplary drafting system S for a ring spinning machine with a compression zone 6 formed between an output pressure roller 1 of the drafting system S and one of these downstream delivery pressure rollers 2.
  • Both pressure rollers 1 and 2 are supported on a delivery cylinder 3 and host a compressor 4 between them , which is pressed for example by means of a (not shown) magnet 18 against the delivery cylinder 3 and held there.
  • the compressor 4 has the task to compress the emerging from the drafting sliver F in the manner known to those skilled in the art. In order to perform its task as well as possible, the compressor 4 must be optimally positioned axially and radially between the pressure rollers 1 and 2.
  • the compressor 4 which will be described in more detail later, lies with its underside 7 flat on the delivery cylinder 3 and leans against the delivery pressure roller 2 with supporting surfaces 9 arranged on its front side.
  • FIG. 1a In the lower part of the Fig. 1a is a representation of the compressor 4 along the section line II - II of the upper illustration in Fig. 1a shown.
  • first compressor duct 8 and second compressor duct 10 can be seen.
  • Fig. 1b shows one of the Fig. 1a similar configuration, in which the essential parts bear the same reference numerals as in Fig. 1a ,
  • the in Fig. 1a and 1b in the middle of its compressor ducts and cut compressor 4 has a first compressor duct 8 in the region of the compression zone 6 and a second compressor duct 10 in its rear wall 12 (eg. Fig. 3d ).
  • the sliver F runs in Fig. 1a from top right to bottom left (in Fig. 1b from right to left) through the drafting system not described in detail and is guided between straps 5 to the gusset between output pressure roller 1 and delivery cylinder 3. Before the gusset, the sliver passes through the rear wall 12 of the compressor 4 and enters the second compressor passage 10.
  • the sliver F When passing through the second compressor passage 10, the sliver F according to the invention the compressor 4 "floating" on the delivery cylinder 3 laterally move, or according to its trajectory orientate. Thereafter, the sliver F passes through the clamping between the output pressure roller 1 and the delivery cylinder 3, and then into the first compressor channel 8 oriented toward the nip line between delivery cylinder 3 and delivery pressure roller 2, in which it is finally compressed and fed through the nip line as compacted sliver VF to the spinning process becomes.
  • Fig. 2a shows an arrangement of a compressor 4 according to the invention, arranged between output pressure roller 1, delivery pressure roller 2 and delivery cylinder 3 of an exemplary drafting system S.
  • the person skilled in the art easily recognizes the position and arrangement of the compressor 4.
  • Fig. 2b shows the arrangement of the compressor according to Fig. 2a Good to see that the output pressure roller 1 slightly “immersed” in the interior 15 of the compressor 4. It penetrates the interior 15 of the compressor 4.
  • FIG. 3a to 3i schematically nine different views of an embodiment of a compressor according to the invention.
  • Fig. 3a shows an embodiment of the compressor 4 according to the invention from below, so - seen in the installed position - from the delivery cylinder 3.
  • Front wall 13, right 19 and 17 left side wall and the rear wall 12 enclose an inner space 15, which, as explained above, the output pressure roller 1, which is in contact with the delivery cylinder 3, penetrates.
  • the rear wall 12 is pierced by the second compressor channel 10 in the embodiment shown here.
  • the breakthrough could also be bridged via a (not shown here) portal, - it would still be a second compressor channel - so that the rear wall 12 would not be interrupted.
  • the two compressor channels 8 and 10 that taper in the conveying direction of the sliver F Fig. 3a , toward the left side of the drawing, extends a head 16 of the compressor 4, which sits on a neck 14.
  • FIG. 3b the compressor 4 is shown in the view from obliquely left rear top.
  • Fig. 3c show him from the front.
  • Fig. 3d the compressor is shown from diagonally left rear below. It can be seen very well the rounding of the bottom 7, with the compressor 4 comes to rest on the delivery cylinder 3 in use.
  • Fig. 3e the compressor 4 from above.
  • the head 16 is as shown advantageously for attaching a typical for the respective compressor designation.
  • Fig. 3f shows the compressor 4 from obliquely left front lower. Good to see here is a left outwardly arched reinforcing rib 21.
  • Fig. 3g the compressor 4 can be seen from the rear. It can be seen well the two aligned compressor ducts 8 and 10.
  • FIG. 3h shows the compressor 4 from obliquely left front top.
  • Fig. 3i the compressor 4 from the left, wherein in the head 16 an approximately triangular fastening device 20 is provided, at which z. B. colored markings 22 can be attached, by means of which one can specify typing of the compressor 4 as sub-cylinder diameter and / or size of the first compressor duct, etc.
  • Fig. 4a shows a further embodiment of a compressor 4 according to the invention from below. All elements described above bear the same reference numerals. Particularly noteworthy here are rounding 24 at the corners of the rear wall 12, which can facilitate the attachment of the compressor 4 during assembly.
  • the head 16 is designed differently than in the embodiments described above.
  • Fig. 4b shows the compressor 4 of Fig. 4a from the left. In the approximately running head 16 z. B. designed as round plugs, caps or pens designed colored markers whose purpose has already been addressed previously.
  • Fig. 4c which shows a view of the compressor 4 from above, the arrangement of the two compressor ducts 8 and 10 can be seen. Based on the illustration of the compressor 4 according to Fig.
