Definitions

  • the invention is concerned with the design of the carding machine for spinning, in particular with a licker-in unit for such machines.
  • the conventional carding machine with several lickerins today comprise a compactor with three rollers of the same diameter, the axes of rotation of which are all in an approximately horizontal plane.
  • These rollers can be slightly smaller than the classic licker-in rollers. For example, they can have a diameter of about 170 to 180 mm, while the classic licker-in has a diameter in the range 250 to 400 mm.
  • the three-roller aggregate generally requires more space than an enema with only one licker-in roller.
  • the diameter of the drum cooperating (the "last") licker-in roller may be selected so that instead of a licker-pull train, a single licker-in roller may be provided.
  • a suitable roll diameter for the last licker-in is therefore 240 to 280 mm.
  • three licker-in rollers are provided, with the first two rollers of the licker-pull train having the same diameter.
  • the rollers could each have a (differing) diameter.
  • the first and last rolls have approximately the same diameter, but the intermediate roll has a smaller diameter.
  • the three rollers may have a common tangent.
  • the axes of rotation of the rollers can lie in a single plane.
  • the common tangent or the single plane may be approximately horizontal or obliquely upward in the direction of the drum.
  • An alternative arrangement is known, for example, from GB 2 043 725 and can also be used in combination with this invention.
  • the present invention may be combined with a conventional size carding drum (1000 to 1300 mm) or a card according to our EP patent application 988100 88.9 (Expected Publication No. 866153).
  • the present invention can also be combined with a system or a filling shaft according to EP 810 309.
  • the speeds or the type of clothing are to be selected such that the master material is completely passed from the upstream to the downstream roller, wherein an opening effect can be generated at the transfer point.
  • Each roll is preferably provided with at least one soil removal site, at least when the card is intended for processing cotton.
  • Fig. 1 The arrangement according to Fig. 1 is given only as an example. The features to be described can also be used in other card types and in carding machines, even in the large machines that are suitable for the production of nonwovens (nonwovens).
  • FIG. 2 shows schematically a feed chute 8 with a cleaner module RM according to EP-A-810 309.
  • the lower part 34 of the chute forms a fiber wadding W, from which fibers are conveyed to a licker-in V by means of a feed roll SW and feed chute SM.
  • Several lickerins can be provided, as indicated by dashed circles V2 and V3.
  • the reference symbol VM indicates a drive motor which is provided for the licker-in V (and possibly for the additional licker-in V2, V3).
  • the sign VA indicates a separating element in the licker-in module and the box VAS schematically represents an actuator for adjusting the element VA with respect to the licker-in.
  • the licker-in V together with the separating element also forms an opening and cleaning device or a cleaning unit.
  • Various units are known which can fulfill the required function, see, for example, DE 40 39 773 and EP 618 318.
  • the cleaning module RM in the shaft 8 and the cleaning unit in the carding infeed can now be linked to the card control 120 so that they can be set together or individually.
  • the setting can z. B. according to EP-B-452 676 (or US 5,181,195).
  • EP-A-810 309 can also be combined with the invention of EP-A-799 915.
  • the content of EP-A 799 915 is therefore incorporated herein by reference.
  • the arrangement according to FIG. 2 represents today's conventional card with three lickerins.
  • the three rollers V, V 2 , V 3 all have the same diameter and their axes of rotation lie in a common horizontal plane (not specifically indicated).
  • EP-A-810 309 does not deal with the diameter of the drum T. It can therefore be assumed that the diameter of the drum T in Fig. 2 has a typical value for the conventional card, that is between 1000 and 1300 mm , The present invention can be used with such drums.
  • EP-A-866 153 will publish at the end of September 1998 a new card which has a "small drum” with a diameter in the range of 700 to 1000 mm.
  • a new card which has a "small drum” with a diameter in the range of 700 to 1000 mm.
  • Such a card (hereinafter referred to as "small card”) is shown schematically in FIG.
  • the drum diameter is smaller
  • the drum of the new card preferably has the same peripheral speed as a conventional card.
  • the spool must be driven at a speed in the range of 500 to 1000 rpm.
  • the spool is configured to be driven at an even higher speed without posing strength, stiffness or vibration problems. The higher centrifugal forces also lead to an increased risk of Gutfaserbuchen. To counteract this, work should be done with a more "handy” set on the spool, so that (compared to the conventional card) the fibers are held “firmer”.
  • An angle ⁇ of at most 90 °, preferably 60-75 ° is sufficient for the stated purpose.
  • the ratio of the diameter D of the drum 50 to the diameter d of the picker 62 is also an important feature of the preferred embodiment of the new card. This ratio is preferably in the range 1.1-1.8 and is thus significantly lower than the corresponding ratio for conventional cards.
  • briseur (licker-in) 58 of FIG. 1 has been replaced in Fig. 3 by several licker-in, for Example according to the principles explained in DE-A-33 46 092 and DE-A-43 31 284, respectively.
  • a higher degree of opening of the fiber material can be achieved before delivery to the spool.
  • the arrangement of the licker-in rollers still corresponds to that published in EP-A 810 309.
  • the solution according to Fig. 3 therefore comprises three lickerins 58, 58A and 58B.
  • the latter licker-in 58B cooperates with the feed roller 56 which takes over the fibers from a wad formed by the hopper F.
  • the shaft is also preferably provided according to EP-A-810 309 with a cleaning device R (see Fig. 2).
  • a common control St is preferably provided for the card and the shaft.
  • the revolving flat aggregate 52 in FIG. 3 comprises approximately 70-90 flat bars 53, of which approximately 20-35 are simultaneously in the working position relative to the drum 50.
  • the traveling lid assembly 52 may be replaced with fixed lids, for example, according to the principles set forth in US-B-3,604,062; US-B-3,044,475 and US-B-3,858,276.
  • At least one additional segment 96 is provided with a soil remover (not shown, e.g., according to our European EP-A-848 091).
  • a soil remover not shown, e.g., according to our European EP-A-848 091.
  • the Nachkardierzone are at least one additional segment 96 or Kardierstäbe (not shown), which can be formed similar to the flat bars 53.
  • several additional segments 96 can be provided both in the pre-carding zone and in the post-carding zone.
  • the drum 50 is otherwise covered by segments 86.
  • the inner drum-facing surfaces of these trim segments 86 may have been processed so as to exert the least possible braking effect on the contacting fibers or, if possible, allow no deposits (e.g., softening of cotton fibers on cotton fibers).
  • These segments must also be adjustable relative to the drum 50 in order to ensure the desired fiber guidance or the predetermined air balance on the drum.
  • a suitable cladding can be found in EP-B-431 482 or EP-B-687 754 and in our EP-A-790 338.
  • the lining or additional segments 86, 96 are indicated in Fig. 3 only schematically.
  • the segments preferably form a continuous lining of the drum.
  • the carding machine can be equipped with a drafting system at the outlet, which can also distort the combined nonwoven fabric by a factor of 1.3 ... 4.0 6.0 allowed.
  • This drafting equipment may additionally be provided with a regulation, for example, according to WO 98/32903 (PCT / CH98 / 00022) or (preferably) according to our further PCT patent application PCT / IB98101357 of Aug. 31, 1998 entitled "Regulated Drafting" for improving the uniformity of the band.
  • a drafting device may be provided on the reel (not shown in Fig. 3, but see the reel K in Fig. 1).
  • the present invention may also be used in combination with a card of FIG.
  • Fig. 4A shows schematically the preferred solution according to the present invention with the drum 100 and three successive lickerins 102, 104, 106, wherein the licker-in 106 cooperates directly with the drum 100.
  • the licker-in 102 accepts fibers (flakes) from a conventional feed in the form of a feed roll 108 which cooperates with a feed trough 110.
  • This feed can be formed, for example, according to our CH patent application no. 2952/97 dated 23.12.1997.
  • the directions of rotation of the rollers are each indicated by a curved arrow.
  • the licker-in 106 has a diameter in the range of 240 to 300 mm, preferably 240 to 260 mm.
  • the lickerins 102 and 104 have the same diameter, for example in the range 150 to 220 mm, preferably 175 to 185 mm.
  • the axes of rotation A1, A2 and A3 of the three licker-in are all in a common plane E, which facilitates mounting on a common support of a frame (not shown).
  • Fig. 4B shows a modification of the card of Fig. 4A in that the number of licker-in is reduced to one to form a "classic card". The remaining licker-in 106 now works together with both the drum 100 and the feed means.
  • the roller 106 can be driven in both variants (Fig. 4A and Fig. 4B) at the same speed, this speed should be in a certain ratio to the drum speed. For a given production and given template weight, there is no change in the feed speed of the feed roller.
  • FIG. 4B The other figures show alternative embodiments for the card with a plurality of lickerins, wherein the corresponding simple arrangements with only one licker-in are no longer shown, since they respectively correspond to FIG. 4B.
  • the drum is indicated at 100 and the "last" licker-in (which cooperates with the drum 100) is indicated at 106.
  • the arrangement according to FIG. 5 comprises only one additional licker-in, namely the roller 112, which cooperates with the feed means 114 and with the licker-in 102.
  • the diameter of the roller 112 is in the range of 170 to 200 mm.
  • the rollers 112 and 106 have a common tangent TG, which is approximately horizontal.
  • Fig. 6 shows three licker-in's 102A, 104A and 106 similar to lickerins 102, 104 and 106, but having a common tangent TG1 for all three licker-in rolls.
  • FIG. 7 shows a further modification with a common tangent TG2 for three licker-in 106, 104102B, wherein the axes of rotation of the rollers are also in a common, horizontal plane E.
  • the roll diameter of the lickerins 102B, 104, and 106 therefore, increases progressively toward the drum 100.
  • the licker-in rollers of FIGS. 4 to 7 may be referred to as "horizontal arrangements".
  • the axes of rotation of the rollers lie in a plane E, which extends obliquely upward in the direction of the drum 100.
  • This arrangement improves access to the last licker-pull 106 and reduces space consumption as compared to the arrangement of FIG. 4A or 7.
  • the rollers 102B, 104 of FIG. 8 could of course have the same diameters as the corresponding rollers 102, 104 of FIG. 4A.
  • the "oblique" arrangement of Fig. 8 can also be obviously modified according to Figures 5 or 6.
  • the arrangement according to Fig. 8 enables a higher wetting column in the feed chute F or 8 (Fig. 1, 2, 3). This results in a longer residence time or a higher compression, which benefits the uniformity of the template on the feed roller.
  • the arrangement of Figure 9 differs fundamentally from those of the other Figures in that the diameter of the first licker-in roller 102C is approximately equal to the diameter of the last roller 106.
  • the middle roller 104C has a significantly smaller diameter than the other two rollers.
  • the licker-in rollers 102D, 104D and 106 of the arrangement of Fig. 10 are also connected in series, but they are no longer "in line".
  • the modified arrangement according to FIG. 10 largely corresponds to the arrangement according to GB 2 043 725.
  • Fig. 11 shows schematically, but in more detail, the working elements which should be attached to the licker-in rollers of a licker-pull train.
  • the train of Fig. 4A with the rollers 102, 104 and 106 is used as an example.
  • the material flow direction is indicated by the arrow M, wherein the fibers of the bottom of the roller 102, the top of the roller 104 and then the bottom of the roller 106 along flow.
  • the sets (not shown) are selected such that the fibers completely pass from the pre-shaded rolls 102 and 104, respectively, to the downstream rolls 104 and 106, respectively.
  • a dirt separator 130 and a garnished carding element 132 is provided on each working side of a roller (underside of the rollers 102, 106, top of the roller 104).
  • the dirt separator 130 can be formed according to EP-A-848 091 or CH / 1303/98 from 17.06.1998 and it can be provided with a dirt removal to CH / 1153/98 from 26.05.1998.
  • Each carding element 132 increases the degree of opening of the fiber material. A similar effect is produced at each transition point from an upstream roll to a downstream roll because the peripheral speeds of the rolls are chosen to produce an opening action. The speeds of the rollers must be selected according to their respective diameter.
  • a downstream licker-in roller rotates e.g. with a peripheral speed of about 1.2 times to 1.6 (preferably 1.3) higher than the peripheral speed of the her vorreisserwalze upstream.
  • the drum 100 rotates at a peripheral speed of 1.3 to 2.5 (preferably 1.7 to 2.2) times higher than the peripheral speed of the last licker-in roller 106.
  • shuttering segments 134 Those stretches of the working sides which are not covered by dirt precipitators or carding elements are covered by shuttering segments 134. Those segments that extend from a carding element into the nearest roll wrap need to carry fibrous material. They are preferably formed according to EP-A-687 754, that is to say as extended hollow profiles made from a light metal alloy. The other formwork segments can also be made according to EP-A-687 754 to ensure the uniformity of the construction.
  • Fig. 8 with a "skew" of the licker-in rollers may also be used in a conventional multiple licker-in arrangement (e.g., of Fig. 2 or Fig. 3), that is, in an arrangement where all rollers have the same diameter.
  • a modern card must be provided with a sheathing, for example a sheath 201 (see schematic figure 12) according to EP-B-585 196.

Rectangular intake openings 209,210 with bars are provided in the doors and air 212 flows through these openings into the shrouded space. This air should flow via suction tubes 213 and suction supports 214 into a collection channel 215 (see also FIG. 13) and along with the card discharge contaminated particles and waste.
  • the whole side of the card, facing the doors 204, 205 is formed as a rolling box 216 which can roll on the ground by means of rollers (not shown).

These motors are attached to substructure 230 and project laterally from the substructure, i. for them, space must be left free between the substructure 230 and the shroud 201 (not shown in FIG. 14). The main motor and other motors are therefore housed in the conventional card between the substructure and the side doors.
  • the working width of the drum 150 should be increased from approximately 1000 mm (FIG. 14) to approximately 1500 mm. Obviously, the assembly of the card can otherwise remain unchanged, the sheathing for it simply be increased.

  • This box can be connected to the frame by hinges (not shown, but Fig. 13) so that the box can be swung away from the machine to allow access to the working elements.
  • This box can form a side cover for the Drum / Picker Rollers.
  • the box 300 can be provided with ribs 400 which project into the gap F1 and are thus overflowed by the air flow flowing into the suction, which causes cooling of the electronic / power parts.
  • doors 402, 404 may be provided on the other machine side, with the sheet metal leading parts being provided on both doors 402 and 404 and having to cooperate with the doors closed to form the channels 302 (Fig. 17).
  • the channel 302 is provided with an extension 406 (Fig. 22), which adjoins the air discharge in the hopper F.
  • the air systems can thus be well combined. It is no longer necessary to provide special air supply openings in the doors. The required air can be introduced from below.
  • the preferred application is in the "cotton karde" (staple fiber spinning mill).
  • the cotton card is different from the Non-wovens card, at least in that in the outlet of the cotton card a sliver must be formed, ie that supplied by the rolls fleece over the working width (or a portion of the working width) must be contracted or combined to form a sliver.
  • the "length" of the transfer zone between the drum and the pickup is not significantly shortened (as compared to the conventional card today).
  • This "transfer zone” may be considered as the area of the drum periphery where the distance between the drum and the pickup is less than a predetermined value (e.g., 0.2 mm).
  • a predetermined value e.g. 0. mm
  • a reduction in the drum diameter leads to a shortening of this transfer zone, if no countermeasures are taken. For this reason, it may prove advantageous to reduce the drum diameter diameter: diameter diameter compared to conventional values today (the diameter of the doffer is at least relatively large and at most absolutely enlargeable).
  • the modules 352, 356 can be introduced into their standby locations.
  • the modules can be mounted outside the card on mobile maintenance equipment (eg slide), for each module first the device is placed in a predetermined position against the card and attached and then the module in its working position by adjusting the device is moved. In this case, the module is already in its ready position when fixing the device.
