Definitions

  • the invention relates to a carding segment for fixed attachment to a carding machine and the use thereof.
  • Revolving flat assemblies consist generally of a plurality of cover-forming casting - rods which are interconnected by means of chains and are guided over a predetermined angular range along the main drum.
  • Each individual cast rod is provided with a scraper fitting, which is relatively easy to assemble and replace, as can be seen, for example, from published European application No. 0 091 986. Thanks to the relatively small dimensions of the cast rods in the carding direction the fittings can be flat, which simplifies their construction.
  • GB-A 2 100 305 discloses a carding segment with a plurality of rows of scraper fittings arranged one behind the other in the carding direction. However, these are fixedly arranged on a common carrier in guides incorporated therein and are therefore neither easily replaceable individually on site nor individually adjustable in their position, but instead the entire carrier must be replaced.
  • a lid card is shown in FR-A 750 191, several rows of scraper fittings being arranged on a concave-shaped lid. Since the fastening of the same lies between the individual rows, there are large gaps in the carding direction, which impair the carding effect. Furthermore, individual rows of scraper fittings cannot be exchanged independently of the others and make it necessary to return the cover card to the manufacturer.
  • This according to the invention is used in a carding achieved by several combined in a frame holder, which are arranged in carding directly behind one another and extend over the carding width at least, each holder for lös - cash receiving arrayed over this width on card clothing forming sawtooth wire strips are formed .
  • the holders are preferably designed to accommodate scratch fittings that can be used in revolving lids, for which purpose in the simplest case they are formed directly by revolving flat bars.
  • the entire frame or parts thereof are preferably designed as an extruded aluminum profile, which on the one hand largely eliminates post-processing during production and leads to relatively light-weight carding segments which can be removed and installed by hand.
  • the carding segment 1 has a frame 2, within which a plurality of holders 3 are combined, on which sawtooth wire strips 4 with clamps 5 are attached as scratch fittings on a support 8.
  • the holders 3 are arranged directly one behind the other in the carding direction, so that there are only slight gaps between the individual fittings and thus essentially a continuous work surface is created.
  • the card clothing extend for this purpose over substantially the entire g e-expansion of the respective holder in carding. If, as in the exemplary embodiments described, flat fittings made of straight sawtooth strips are used, this work surface consists of a series of tangent surfaces to the main roller 6.
  • Each tangent surface thus geometrically has a line contact with the circumference of the main roller 6, the position of this line of contact the fitting can be selected for each holder independently of the others. Thus, at least in the inlet-side holder, this line of contact will rather be displaced from the inlet we g , which corresponds to a certain angle of attack.
  • the individual setting can be made by designing the support surfaces for the holder on the frame 2 or by dimensioning the holder itself.
  • the frame 2 and the holder 3 are further configured such that the scraper fittings 4 can be replaced individually.
  • a clamp connection known per se is used, as is common with revolving cover arrangements.
  • the brackets 5 extend across the width of the card and are anchored to corresponding surfaces 7 of the holder 3.
  • the Holders 3 are now preferably configured in the corresponding area in the same way as existing revolving covers, so that both the same sawtooth wire strips and the same clamps can be used in both and can be removed and attached using the same auxiliary machines.
  • the frame 2 in which the holders are combined is constructed from torsion-resistant profiles, for which aluminum profiles are used at least over the card width, as will be explained in more detail.
  • the design according to FIGS. 1 and 2 has the special feature that the cast rods of a revolving flat card are used as holders 3. These rods are screwed at the points 9 with longitudinal struts 10 of the frame 2, which are adapted to the circumferential shape of the main drum 6 and are made of steel.
  • the cross struts 11 of the frame consist of rigid aluminum profiles which are screwed to the longitudinal struts at the corners. Since the cross struts have a much greater length (ie between approximately 1 m and 1.5 m) than the longitudinal struts (less than 0.2 m in the exemplary embodiment), the weight reduction achieved for the frame is considerable, so that segment 1 is made by hand can be installed and removed. Lateral handles 12, which are arranged on the side walls, serve this purpose.
  • the segment 1 is detachably connected to the machine frame at the corners by means of screw connections 12.
  • a detachable sheet metal top 14 prevents dust from escaping.
  • the fittings can be replaced separately for each holder 3. For this purpose, this is released from the frame 2, after which the clamps 5 are opened in a conventional manner and the sawtooth wire strips lined up on the carrier 8 are replaced as a whole can be.
  • the position of the individual fittings with respect to the main drum 6 can be carried out by appropriate processing of the support surfaces of the holder 3 on the frame 2.
  • FIG. 3 and 4 another embodiment of the invention is shown, in which the holder 3 are formed integrally with the frame 2 from an aluminum profile. Because, in contrast to the first exemplary embodiment, the holders themselves are also made of aluminum, further weight savings can be achieved.
  • the individual holders 3 are defined by slots 15 which are milled into the aluminum profile. These slots 15 serve to receive the brackets 5 for the fittings. These clips are released for replacing the fittings from the top of the segment, so that the slots 15 are accessible from above.
  • cross bars 16 can be detachably screwed onto the holders 3 at intervals of approximately 30 cm.
  • the position of the fittings relative to the main drum is adjusted by arranging the lower surfaces of the holders 3 accordingly. This can be done directly during the extrusion of the aluminum profile, so that post-processing is not necessary.
  • this segment is produced by extrusion of the corresponding aluminum profile, in which the slots 15 must then be milled and the various threaded holes drilled. No further processing is necessary.
  • a third embodiment of the invention is shown, in which the frame 2 is designed like a lid. As a holder 3 strips are provided, which are detachable by means of screws 16 on the frame 2 are attached.
  • the frame is designed as an extruded aluminum profile. Compared to that, it has a high degree of rigidity without any special measures, since no transverse slots are provided in it. Means for connection to the machine frame, in particular screw holes 13, are provided on the side of the frame, as in the other examples.
  • the corresponding holder 3 is unscrewed from the frame.
  • the clamps 5 can then be opened on the released holder 3.
  • the position of the fittings in relation to the main drum 6 can be determined by the dimensioning of the holder 3.
  • FIG. 7 is shown approximately in its original size, the frame 2 being formed from a plurality of profile carriers which extend over the card width, namely the actual frame profiles 20, 21 and a support profile 22 for the holder 3.
  • the support profile 22 is in one piece and consists of a casting of a metal, preferably an aluminum alloy. If necessary, it can also be designed as a drawn profile part.
  • the holders 3 are of a similar design as in the embodiment according to FIG. 5 and are also detachably and adjustably fastened to the support profile 22 with screws 16, so that the scraper fittings 4 are replaced in the manner described there.
  • the design according to FIG. 7 is shown approximately in its original size, the frame 2 being formed from a plurality of profile carriers which extend over the card width, namely the actual frame profiles 20, 21 and a support profile 22 for the holder 3.
  • the support profile 22 is in one piece and consists of a casting of a metal, preferably an aluminum alloy. If necessary, it can also be designed as a drawn profile part.
  • the holders 3 are
  • a cover plate 23 prevents dust from escaping through the openings between the frame profiles and the support profile.
  • the number of holders provided in a frame 2 can be substantially between 2 and 4 in all versions.
  • the upper limit results from weight reasons, since the segments 1 should preferably be able to be lifted by hand.
  • the segments 1 according to the invention are preferably arranged in the area of the inlet above the licker-in or the outlet above the consumer. In the first case, frames with 2 to 3 brackets are preferred for reasons of space, in the second with 3 to 3 brackets.
  • the segments according to the invention can be provided as a single carding element when combining several individual segments. Preferably, however, they are used together with revolving flats, wherein the sector can be reduced thereby possibly (about 60 ° to 30 0). Furthermore, the segments can also be combined with pairs of workers and migrants.
  • the segments according to the invention primarily have the function of fiber parallelization, while the movable elements are used for cleaning.
  • the structure of the scraper fittings on the individual holders 3 can be selected differently from holder to holder, the fineness of which can be successively increased from the inlet side to the outlet. This allows an optimization of the parallelization effect of the segment.
  • segment according to the invention is superior to the known flat cards both in terms of manufacture and maintenance and also in its mode of action in combination or depending on the material processing (synthetic fibers) even without the use of revolving flat cards.
