Definitions

  • the present invention relates to a lid cleaning system for a card equipped with a peripheral set of lids, the individual, non-contacting lids of which consist of a T-shaped profile, the legs on both sides of which carry a lace set on their working surface and the web against the interior of the lid set Cover space is directed, and in which the cover strand located on the drum is guided along the surface of the carding drum, and in which in the area of the cover strand located on the drum, the space between the webs of two adjacent covers is essentially airtight and over the whole by a closing element
  • the length of the cover can be closed to form a channel and means for generating an air flow are assigned to the channel.
  • a lid cleaning system for a circumferential set of lids is known (US Pat. No. 4,075,732) whose individual, non-contacting lids consist of a T-shaped profile, the legs on both sides of which carry a lace set on their working surface and whose web against the interior of the the lid set formed lid space is directed.
  • a flexible sealing element extending over the entire length of the webs is provided, in such a way that a channel corresponding to the length of this sealing element is formed.
  • the sealing element is in each case a U-shaped, elastic element clamped between two webs or in the other case an elastic, covering all webs elastic sheet, which is connected to the side chains driving the webs.
  • the sealing elements mentioned. the channels adjoin suction hoods arranged on the side in order to thereby generate an air flow between the cover distances and through the channels.
  • GB-PS 1 038 426 shows a suction hood which extends essentially over the length of the cover and which has a width which essentially corresponds to the distance between two cover webs.
  • the present lid cleaning system has the task of eliminating the above-mentioned disadvantages of the known devices of this type and of creating a lid cleaning system in which the lid space is effectively cleaned with low power consumption while avoiding any formation of air vortices and dead zones.
  • the end element consists of a fixed, flexible band, which is supported on the webs on these.
  • a third solution to the problem is that the end element is formed from a body that rolls on the webs of the cover.
  • the temporary formation of a channel closed by the legs and webs of two adjacent lids and by the closing element creates optimal conditions for the removal of the airborne and dirt particles located in this room, in that it is sufficient to generate an air flow therein which, thanks to the compared to the entire cover space, small duct dimensions can be guaranteed with a relatively small output. Because the duct formed is essentially airtight with respect to the cover space, the air flow acting in the duct can exert no influence on the remaining air in the cover space and, in particular, can not generate any excess pressure in this space. It is therefore also possible to keep the lid space slightly under pressure using conventional means and thus to meet the desired environmental conditions.
  • the closure element can also extend over a plurality of adjacent lids.
  • the end element extends essentially over all the covers located on the drum.
  • the means for generating an air flow in the duct can include a suction line opening at the end of the duct.
  • Fig. 1 is the drum of a so-called revolving card, while 2 represents the breeze, 3 the customer and 4 the feed roller.
  • These 4 rolls are rotatably mounted on both sides - with bearings (not shown) in an only indicated card frame 5 or 5a (see also FIG. 2) and are supported by means of which the pulley 6 for the drum 1 is shown only in FIG. 2 is shown, driven in rotation with certain mutual speed ratios and directions of rotation.
  • the fiber material in the form of a flake layer is offered to the feed roller 4 rotating in the direction of arrow E by means of a trough-shaped feed plate 7, gripped by the teeth of the tip set 8 of the beater 2 and removed in the direction of arrow F.
  • the drum 1 also has a lace set 9, which is particularly in Fig. 3, where an enlarged detail, among other things. the drum periphery is shown is visible.
  • the tips of the tip set 9 of the drum 1 take over the fibers or fiber flakes from the set 8 of the breeze and, following the rotation of the drum 1 in the direction of arrow G, bring them to the point of delivery thereof, namely to the point of contact between the drum set 9 and the tip assembly 10 of the customer 3, which in turn rotates in the direction of the arrow H.
  • the fibers or fiber flakes are passed to the customer 3 and passed to the carding device, not shown.
  • the actual carding of the fiber material takes place in the zone of the drum 1 located between the dispensing stations Briseur 2 / drum 1 and drum 1 / pickup 3 by the fibers lying on the surface of the drum set 9 (FIG. 3) between the drum set 9 and the tip set 11 (Figs. 2 and 3) are pulled through from the slowly moving card deck 12 (or 12a, 12b, etc.).
  • the card covers 12, 12a, etc. are connected as a slowly rotating set of covers 13 by chains or connecting elements 14 and 14a (FIG. 2) located at both ends of the cover, so that they form a closed structure, the interior of which is shown here lid space 15 formed by the lid set 13 is designated.
  • the covers 12, 12a, 12b etc. consist of a T-shaped profile, the legs 16 and 16a on both sides (FIG. 3) of which carry the lace set 11 on their working surface 17 and whose web 18 is directed against the interior of the cover space 15.
  • the T-shaped cover profiles, as shown in FIG. 1, extend over the entire width of the reel 1 and are on both sides by means of sliding shoes 19, 19a on curved guides 20 or concentric with the reel 1 formed by the walls of the card frame 5 and 20a along the surface of the drum 1.
  • the lid set 13 consists essentially of two lid strands, namely the strand 21 on the drum 1 and the return strand 22, and two lid reversal points 23 and 24, the structure of which is known in practice, so that its description can be dispensed with.
  • the covers lie along the cover run 21, where the covers are in the working position 12, 12a, etc., as shown in Fig. 3, lined up.
  • the legs 16, 16b of the adjacent lids 12, 12a are close to one another, but there is no mutual airtight seal between the legs 16 and 16b, ie the lids 12, 12a etc. do not touch.
  • a long, narrow gap 25 thus arises between the lids, through which individual fibers or small fiber structures can penetrate from the drum surface into the lid space 15 and settle there, in particular in the space formed between two adjacent lid webs 18 and 18a on the inside of the lid.
  • FIG. 2 it can also be seen how the covers 12, 12a, 12b etc., also along the return strand 22 by means of curved guides 26, 26a, are also guided practically concentrically to the drum 1, in this example the sliding shoes 19 and 19a again Application come.
  • the guides 26 and 26a are formed by two carriers 27 and 27a fastened to the card frame 5 and 5a.
  • the entire space of the lid set 13 is further covered from the surroundings by means of a hood 28 which is essentially sealed off from the surroundings (not shown) in such a way that its interior 29 can be kept in negative pressure by connection to an external suction source, the Negative pressure should be of the order of a few mm water column.
  • a vacuum is sufficient to prevent fibers from escaping from the hood 28 into the environment, but not to deposit the fibers and fiber flakes that have entered through the gaps 25, 25a, etc. (FIG. 3) in the lid space 15 onto the Cover 12, 12a, 12b, etc. to counter effectively.
  • the inventive lid cleaning system is now used, in which in the embodiment variant of FIGS.
  • a stationary end element 30 is provided via the lid webs 18, 18a, 18b etc., on which (see FIG. 3) the free end of the web 18, 18a, 18b etc., moved past, forming a sealing point.
  • the end element 30 (FIG. 3) has the shape of a plate 31 following the curvature of the cover sheet, which may be made stiffer by ribs, not shown, so that the surface 32 facing the webs 18, 18a, 18b, etc., is practically contact-free and may be substantially airtight over the entire width of the lid 12. It is attached laterally by ear flaps 33 and 33a to the carriers 27 and 27a by means not shown.
  • a suction line 36 - (Fig. 2) opens. 1 to 3, 37 designates the end opening of the suction line 36.
  • the line 36 is connected to suction means (not shown), whereby a suction flow according to arrow f of the figure is generated in the channels 34 and 35 (FIG. 3), through which the fibers, fiber flakes and impurities accumulated in the channels 34 and 35 are discharged will.
  • suction means not shown
  • the mouth 37 of the suction line 36 is drawn so wide that it extends over two adjacent channels 34 and 35 and thus simultaneously generates an air flow in both channels 34 and 35.
  • the mouth 37 may also only be wide enough that an air flow is generated in a single channel between two cover webs. Since the set of covers, as previously said, moves slowly (the direction of this migration is irrelevant here), each cover 12, 12a, 12b etc. then comes to stand under the end element 30 from time to time, so that each cover comes with temporarily forms a channel in its neighboring cover, in which the cleaning flow becomes effective.
  • the closure element 30 does not need to extend over a plurality of décors 12 and 12a, 12b, as shown in FIGS. 1 and 3. It is sufficient that z. B. extends over the two webs 18, 18a of two adjacent lids 12 and 12a, so that the airtight channel 34 is temporarily formed. For reasons of shape stability, however, it is advisable to use an end element 30 which extends over a plurality of lids.
  • Each lid comes under the closing element 30 or the plate 31 during its migration, and the suction flow causes the passage through the channel and the desired cleaning effect. It should also be mentioned the fact that the entire suction flow also makes it possible to put the entire interior 29 of the hood 28 under the desired slight negative pressure, which creates the favorable conditions for the ambient air described above.
  • the hood 28 can, however, also optionally be connected to its own suction line (not shown).
  • the closure element 30 extends essentially over all the lids 12, 12a etc. of the lid strand 21 located on the drum 1 and consists of a fixed, flexible band 38, which extends over the webs 18, 18a etc., the cover 12, 12a etc., supports and is anchored in the lid reversal points 23 and 24 by means not shown.
  • the flexible band 38 which is preferably a plastic band, converts all the spaces between the webs of the covers 12, 12a, etc., of the cover strand 21 into closed channels
  • the air flow according to the invention can only be in or in the area of the front opening 37 of the suction line (not shown) located channels are effective, which also ensures the effectiveness of the suction despite the small amount of air (and thus the low energy consumption).
  • the solution shown here has the advantage over that of FIGS. 1 to 3 that it makes it possible to separate the lid space 15 into two practically separate spaces, namely above and below the band 38, with the effect of the gaps 25, 25a, etc. between the covers 12, 12a, etc., which in the solution of FIGS.
  • FIG. 4 shows the use of two support rollers 39 and 40 for the return strand 22 of the cover set 13 instead of the guides 26 and 26a of FIGS. 1 to 3, which can mean that the construction may become cheaper.
  • the flexible plastic band 38 is preferably chosen as a thin band, the web side, i.e. the side which is directed towards the free end of the webs 18, 18a (cf. FIG. 3) has a low-friction and electrostatically poorly chargeable surface.
  • the sliding friction of the drive of the cover set 13 can thus be reduced and the electrostatically induced sticking of the fibers to the sliding surface of the belt 38 can also be prevented.
  • band 38 e.g. a polyester tape of the type Transilon E2 / 1-UO / V2 with PVC covering from Siegling AG, Postfach 5346, D-3000 Hannover-1, can be used.
  • FIG. 5 shows a further variant of the lid cleaning system according to the invention, which differs from the variants of FIGS. 1 to 4 discussed so far in that the end element 30 is not stationary here, as in the earlier variants, but an inherent one the webs 18, 18a, etc. are used.
  • a peripheral band 41 is used as the end element 30, which is stretched between two rotatably mounted rollers 42 and 43 and is supported with its lower run 44 on the free end of the webs 18, 18a etc. of the covers 12, 12a etc.
  • the band 41 can thus the displacement of the lid set 13, e.g. in the direction of the arrows I (the role of the deflection point 23 then rotates counterclockwise, as the arrow L shows), preferably at the same speed, i. H. the tape runs around the rollers 42 and 43 also counterclockwise (arrow M on the roller 42).
  • the band 41 can be equipped with its own drive, not shown, or it can also be taken only by friction through the webs 18, 18a, etc., from the covers 12, 12a, etc.
  • the band 41 extends of course over the entire width of the covers 12, 12a etc., and is laterally sealed and / or guided accordingly by means not shown.
  • a suction opening 37 is provided on the side, which, as in the embodiments described above, for the formation of a suction flow in one or more channels enclosed between the covers 12, 12a, etc. (in the example shown, the band 41 forms four such channels) is connected to a suction source, not shown.
  • FIG. 5 has the advantage that the airtight closure of the space between the webs 18, 18a, etc., of two adjacent lids is ensured without friction.
  • Fig. 6 shows a further variant of a lid cleaning system according to the invention, in which the end element 30, like that of the variant of Fig. 5, is formed as a rolling body on the webs 18, 18a, etc., with similar advantages as that previously mentioned can be achieved.
  • the end element 30 is designed as a roller 45, which is guided in two lateral bearings 46 (only one shown) so as to be radially movable to the surface of the reel 1 and is temporarily on two webs 18, 18a of two adjacent card covers 12, 12a supports with its cylindrical surface and thus closes the inventive longitudinal channel 47 between the webs 18, 18a.
  • the roller 45 By the moving movement of the lid set 13, z. B. in the direction of arrow I, the roller 45 is rotated counterclockwise (arrow N), the roller 45 also making a vertical movement and possibly e.g. supported on a single web 18a.
  • various measures can then be taken, if necessary or desired, such as. B. to provide the roll 45 with a soft coating, not shown, or to give the roll 45 a certain freedom of movement in the direction of the lid migration, that is, according to arrow I.
