Definitions

  • the present invention relates to a spinning preparation machine, in particular a carding machine, with a feed roller together with a body carrying the associated feed trough, a loosening roller with tips and a loosening area for the fiber material located between the feed roller and the loosening roller and one between that through the tapering surface of the Loosening roller and the surface of the feed roller formed converging space located suction device.
  • open-end spinning is becoming more and more popular because it is more economical than the older ring spinning process in certain yarn count ranges.
  • open-end spinning has the disadvantage that it is sensitive to dirt present in the fiber slivers to be fed. It is primarily the contaminants consisting of micro dust and short fibers that accumulate on the inner wall of the rotor during the spinning process and adhere there, which leads to the formation of an increasingly uneven yarn and ultimately to yarn breaks.
  • a suction device on cards is already known (DE-AS 1'685'552), in which a vacuum hood with a suction slot facing the licker-in roller is arranged directly above the feed roller.
  • the hood is intended to suck off the fibers that have adhered to the corrugated feed roller, in that the feed roller is swept from both sides by air flowing into the hood.
  • only the fibers released by sharp deflection of the lap wadding at the end of the dining table trough are to be sucked off by means of the suction slot, which is desirable because of their reusability.
  • the invention is based on the object of overcoming the disadvantages mentioned and freeing the fiber material as effectively as possible from the annoying dust in the subsequent processes and preventing it from freely escaping into the atmosphere of the work space.
  • This object is achieved in that the feed trough body reaches into the converging space as far as the loosening area and there a suction opening of the suction device opens.
  • the suction opening can be formed, on the one hand, by a nose which extends up to the loosening area and extends along the feed trough, and, on the other hand, by a trough plate which runs somewhat less far and extends at a distance.
  • This design is advantageous in that the suction air flow can enter directly on the nose, which increases its effectiveness and allows a very simple construction.
  • a further development consists in that the loosening area formed with a further loosening roller over a is connected to the suction device between a cover and the surface of the first loosening roller. This makes it possible to detect a further source of dust without additional effort, such as special channels or cover hoods.
  • the feed trough body can advantageously contain air passage passages which are lined up along the length of the feed trough and end at the suction opening and which open into a common air vent housing. This is advantageous because it serves to better distribute and stabilize the suction flow within the body, so that the suction effect is uniform everywhere.
  • the feed trough body together with the suction device can be moved away as a unit from the feed roller on a fixed path. This allows the converging space between the rollers to be exposed for maintenance purposes in a simple manner in terms of handling and also to check and clean the passages in the bowl body.
  • a feed roller 1 (FIG. 1) is provided on its outer surface with flutes, corrugations, coarse teeth, tips 2 or the like and can be driven in the direction of arrow A.
  • a feed trough 3 located above the feed roller 1, worked out of a trough body 4, and a trough plate 5 attached thereto extend parallel to one another in the axial direction.
  • the fiber material 6 to be conveyed is located between the feed roller 1 and the trough 3, for example in the form of a lap-wadding web.
  • a loosening roller 7 is provided with fine teeth or tips 8; it can be driven in the direction of arrow B, ie opposite to the direction of rotation of the feed roller 1. In operation, the roller 7 has a much greater circumferential speed than the roller 1.
  • the trough body 4 has a nose 9 that extends approximately to the location of the smallest distance E of the two rollers 1 and 7. Between this and the somewhat less protruding trough plate 5 There is an air extraction duct 11 with the suction opening 12 in the converging space between the cylindrical surface of the loosening roller 7 tapering to a loosening area 10 and the cylindrical surface of the loosening roller 1 also tapering into this area At this point, the loosening roller 7 lying directly opposite and the feed roller 1 begins, the fiber material 6 presented is detected and loosened in the process.
  • the loosening roller 7 also does not fully work with a drum 13 provided with even finer teeth or tips and functioning as a second loosening roller, for example one in FIG. 1 shown card, together, which rotates in the direction of arrow C.
  • the increasing lengths of arrows A, B, C are intended to indicate that the peripheral speed of each subsequent cylinder is greater than that of the previous one.
  • a suction arrangement comprises, in addition to the air extraction duct 11 consisting of the trough body 4 and the trough plate 5, an adjoining air extraction housing 15 which extends along the feed trough 3 and to which an approximately equal-length suction nozzle 16 which distributes the vacuum is connected and which is connected via a flexible or extendable one Line 17 is connected to a vacuum generator (not shown).
  • the trough body 4, the air vent housing 15 and the suction nozzle 16 are assembled into one unit and carried by support arms 18 (only one arm visible in FIG. 1), which can be pivoted about a bearing 19 which is fixed to the frame, i.e. the unit can be moved away on a fixed track. In operation, the unit is of course secured against the machine frame (not shown).
  • the trough body 4 together with the parts 15, 16 can be folded away from the feed roller 1. This enables easy access to parts 1, 3, 7 and 11, e.g. for the purpose of inspection and cleaning of the same.
  • the trough body has 4 holding members 22 (FIG. 2) in the form of ribs.
  • the trough plate 5 is detachably screwed to this by means of screws 23.
  • the air exhaust duct 11 is thus divided along the feed trough 3 into a plurality of individual air passages 24, each of which is laterally delimited by two adjacent holding members 22. All passages 24 lead transversely between the body 4 and the plate 5 to the air vent housing 15.
  • the fiber material 6 is pressed by the feed roller 1 in the trough 3, released by the trough 3, whereby it springs open due to the inherent elasticity. In the loosening area it is then loosened by roller 7 and pulled apart. A substantial part of the impurities present in the fiber material 6, in particular fine dust adhering to this (micro dust), is released. Dirt that is not released is loosened to such an extent by the fiber material 6 that it can be released in one of the next loosening areas.
  • the air moving with the rapidly rotating cylindrical surface of the loosening roller 7 in the channel 21 is prevented from passing through the narrowest point E between the two rollers at the loosening area 10 because of the small distance between the surfaces of the two rollers 1 and 7 and the expanded fiber material lying between them .
  • the released impurities are thus detected by the suction air flow originating from the suction opening 12 and then transported away with the air moved by the air extraction duct 11 and the suction arrangement formed from the parts 15, 16 and, after filtering off the impurities, are released into the open air.
  • the suction effect emanating from the suction opening 12 is of such a strength that the air supplied between the loosening roller 7 and the cover 20 to the loosening area 10 is sucked off completely, since then a build-up of a dynamic pressure in front of the loosening area 10 and thus an axial one Drainage and lateral escape of polluted air into the factory hall avoided, or a special seal can be dispensed with.
  • the fiber material When changing over from the loosening roller 7 to the reel 13 in the loosening area 14, the fiber material is loosened again, whereby any other previously loosened impurities are removed. These are carried along with the air flow flowing in the connecting duct 21 and, after being sucked into the duct 11, are likewise carried away by the suction arrangement (parts 15, 16). A separate channel outside the cover 20 can thus be dispensed with.
  • the device according to the invention is advantageous insofar as the feed trough serving for fiber feeding is fed into the converging space between the feed roller and the loosening roller, e.g. the licker-in roller of a carding machine, and the suction opening of this channel is thereby brought close to the dust development point.
  • this arrangement can decisively reduce or completely suppress the lateral exit of the polluted air carried by the loosening roller.
