Definitions

  • the invention relates to an adjusting device on a card according to the preamble of claim 1.
  • Fig. 1 shows an arrangement known from EP-A-432430. It comprises an element 4, which extends below and along the drum roll 1, in the transition zone between the drum 1 and the consumer 2. This element 4 serves to guide the air in the diverging gap between the drum 1 and the consumer 2.
  • EP-A-432430 there is an adjustment device 4 which extends below and along the drum roll 1 on the side of the take-off 2 (see FIGS. 1, 2 of EP-A-432430), known.
  • the adjusting device comprises a guide plate, also referred to as a tongue, and has the task of optimally controlling the air flow in the diverging gap between the drum and the consumer.
  • Another solution is shown in JP 51-36011.
  • the gap A (Fig. 1, EP-A-432430) is defined between the reel and the tongue, so that the air flow from the gap in directions of rotation II and III of the reel and Customer is distributed in a certain proportion.
  • cotton fibers of approx. 25 to 30 mm it must be correspondingly smaller so that the tongue guides the air currents from the gap in the direction of the customer 2 in order to support the transfer of the fleece from the reel to the customer.
  • man-made fibers of approx. 38 mm and longer which are more easily transferred to the customer than the short ones, the air flow should be guided to a greater extent in the direction of rotation II of the drum.
  • the tongue 4 has a foot part 6, which is fastened by means of screws to a support 8, which in turn is firmly connected to a machine frame part 9 at a foot end.
  • the tongue is adjusted with screws 7 which are guided in slots 10 in the foot part 6.
  • EP-A-432430 is not concerned with the question of access to the screws 7. Because of the covering of the card, which is essential for a modern machine, access to the parts to be adjusted is difficult and at least requires that the covering in the lower Area of the drum must be removed beforehand.
  • an adjusting device is known from the prior art according to FIGS. 3 and 4, which is installed in the card C50 of the applicant.
  • the tongue 4 is arranged at one end on a so-called convertible top segment 14, this segment forming an element of the corresponding drum shield, as will be explained in more detail below with reference to FIG. 5.
  • the segments 14, which are each provided on one side of the card, serve to carry top elements, e.g. from US 5142742 or EP-A-431482.
  • the segment 14 is divided into two legs 11, 12, where their adjustment takes place.
  • the adjustment is carried out by means of two screws 30, 40.
  • the screw 30 comprises a first part 30A, which is screwed into a threaded bore in the leg 11 and is provided with a locking nut.
  • the part 30A serves as a support surface for the second part 30B, which is screwed into a threaded bore in the leg 12.
  • the part 30B serves to spread the legs 11 and 12, which are designed to be elastically bendable.
  • Screw 40 serves as a fastening or clamping screw.
  • the tongue 4 is fastened to the lower leg 12 by means of a separate screw (not shown).
  • the gap A to be set is located between the tongue 4 and the cylindrical outer surface 1A of the clothing that is mounted on the drum (not shown).
  • the adjustment with screw 30 causes a displacement of the lower leg 12 and thus also of the tongue 4 with respect to the drum surface 1A.
  • the gap A in FIG. 4 is thus adjusted at one end.
  • An identical arrangement is provided at the other end of the tongue so that the gap A is below the Reel drum can be adjusted across the entire working width of the reel using the two adjustment means.
  • screw 30B If screw 30B is screwed in too much, it creates plastic (permanent) deformation, which may no longer permit correct adjustment. Furthermore, the clamping screw 40 can deform the leg 12.
  • the object of the invention in its first aspect is to provide an adjusting device for a card, the adjustment of which is simplified. This object is achieved with the features of claim 1.
  • the arrangement can be made such that access from the outside of the drum shield is guaranteed.
  • the invention also enables a simplified assembly of the adjusting device.
  • Embodiments of the invention have the advantage that access to the adjusting screw is simplified since it is turned by the drum shield. Fixing the setting is also simplified, for example with a lock nut on the adjusting screw, since the nut can lie on the drum shield.
  • Another advantage of a preferred embodiment is that access to the tongue mounting screw i.e. to the screw, with which the tongue is fastened to the leg, is simplified since this screw can be easily reached with a tool through an opening in the drum shield.
  • the invention also relates in a second aspect to an aid (a guide element) for use in the drum / customer transition zone of a "cotton card", in particular a revolving card.
  • a "cotton card” does not exclude the use of the machine for processing man-made fibers, it merely means the construction or design of the machine for processing fibers with a staple length that is similar or corresponds to the staple length of the cotton fibers.
  • the present invention is suitable for use with an adjustment device according to the first aspect, but is not limited thereto.
  • the invention in its second aspect further provides an aid for influencing the employment relationships in the area where the fleece is formed and removed.
  • the aid also comprises a guide element which extends over the working width and which covers part of the outer surface of the drum.
  • the guide element preferably adjoins a further covering of the drum. In the preferred arrangement, this further cladding is provided without interruption up to the area of the drum tearing machine, the provision of openings in the casing of the sub-carding zone not being excluded by this invention.
  • the element can be provided with a curved surface facing the air or fiber flow, the curvature of which has a radius of not less than 4 mm (R4), preferably 6 to 10 mm (R6 to R10).
  • Said curved surface preferably flows smoothly into a further curved surface, which, viewed from the drum, forms the outside of the guide element.
  • the element can have a surface which forms a wedge gap tapering in the flow direction with the lateral surface of the drum.
  • the latter surface can be formed by a part of the former curved surface.
  • the guide element can be adjusted such that the size of the working gap (ie the distance between the guide surface and the outer surface of the drum) is less than 0.8 mm (and preferably less than 0.6 mm) at the transition to the further cladding.
  • the size of the above is Working gap 0.4 mm.
  • the arrangement can be such that a working gap of less than 1.5 mm (preferably less than 1.2 mm) is made possible at the end of the cladding in the vicinity of the licker-in. In the preferred arrangement, the latter working gap is 0.7 mm.
  • FIG. 5 schematically shows a revolving flat card 100 known per se, for example card C50 from the applicant.
  • the fiber material is fed into the filling shaft 102 in the form of dissolved flakes, taken over by a licker-in 103 (also called “Briseur”) as a wadding and passed on to a drum 104 (also called “Tambour”) as largely opened and cleaned material.
  • the drum is driven so that it rotates about its own axis in the direction indicated by the arrow.
  • the fiber material forms a fleece on the cylindrical surface of the drum 104 provided with a clothing (not shown), which is carded in the "main carding zone" (between the drum 104 and a traveling cover set 105), with both short fibers and finer dirt particles being removed and Nits can be dissolved or removed.
  • the revolving covers are from carried by a traction means and move around deflection rollers 106 in the opposite direction to the direction of rotation of the drum 104, or in the same direction.
  • Fibers from the nonwoven fabric located on the drum 104 are removed from a take-off roller 107 and formed into a carding belt 109 in an outlet section 108 consisting of different rollers.
  • This tape is deposited by a tape storage device 110 in cycloidal turns in a transport can 111.
  • the present invention is concerned with the design of the so-called "sub-carding zone", i.e. with the drum section between the take-off roller 107 and the licker-in 103, and in particular with the transition zone drum / take-off roller.
  • this transition is particularly delicate since it cannot be clearly predetermined whether a fiber on the drum continues to move with the drum or detaches from it and combines with the removed nonwoven.
  • it is therefore known to provide aids in the transition zone which are able to influence the conditions in the transition zone. It is important that the tool can be adjusted to set the conditions and that the set conditions are continuously maintained over the entire working width of the transition zone (approx. 1 m) during operation.
  • FIG. 6 schematically shows a side view of a card frame with a substructure 112 and a drum shield 113.
  • the substructure 112 comprises two side walls 114 (only one of which can be seen in FIG. 6), each of which offers an upwardly directed support surface 115.
  • the assemblies which contain the working elements are supported on this support surface 115.
  • FIG. 6 only the assembly comprising the invisible drum 104 is indicated, since the other assemblies play no role in the invention.
  • the drum shield 113 comprises a hub 116, in which the axis 117 of the drum is rotatably mounted.
  • the hub 116 is in one piece with a plate-shaped wall 118 cast, which has various reinforcing ribs protruding outwards, only the ribs 119 shown in FIG. 6 for the sake of clarity, which merge into two support elements 120.
  • the elements 120 sit snugly on the support surfaces 115 and they are fastened to the side walls of the substructure 114.
  • the second drum shield On the other side of the card is the second drum shield, arranged in mirror image opposite the shield 113.
  • the edge portion 121 of the wall 118 of each drum shield is used for fastening or for positioning various elements which work directly or indirectly with the drum in the processing of the fibers, that is to say extend over the working width of the drum.
  • the edge section 121 is provided with a so-called flex bend (not shown) which serves as a sliding surface for the revolving cover in its workplaces - see, for example, in this connection DE Patent Application No. 96101466.9 from 2.2.96.
  • the edge section 121 is provided with the so-called convertible top segment 14 (FIGS. 3 and 4), which is used to fasten the above-mentioned elements.
  • the segment 14 extends over the entire sub-carding zone, since apart from the tongue 4 (FIG. 3) it has to carry various top elements (for example elements 50 according to US Pat. No. 5,122,742).
  • the following description deals only with a partial area of the drum shield 113, namely the area 122 (FIG. 6) in the sub-carding zone, next to the take-off roller (not shown in FIG. 6).
  • the area 122 is shown isometrically but still schematically in FIG. 7. As can be seen there, the outside of the wall 118 (i.e. the side that remains accessible to the user even during operation) is provided with a cutout 123 between the ribs 119 and then on the edge portion 121. In this recess 123 there are adjustable elements according to the invention.
  • the convertible top segment 14A is designed as an arc and received in a receiving groove which is provided in the edge section 121 in the sub-carding zone but is not visible in FIGS. 6 and 7.
  • the arch 14A is fastened to the shield 113 by means of two bolts 126 which, when assembled in respective threaded bores, are formed in one piece with the arch 14 125 can be screwed (see also Fig. 9).
  • the bolts 126 push through an opening in the bottom of the receiving groove, the opening opening in the vicinity of the removal roller in the recess 123 (FIG. 7).
  • the corresponding bolt 126 extends from its shoulder 125 to a rib 124 (FIG. 7) which serves as anchoring for the arch.
  • the arrangement of the recess or anchoring rib is also provided in the vicinity of the licker-in (not shown in FIG. 7), so that the two fastening bolts 126 are fastened to the shield in the same way. Accordingly, the bolts 126 are very easily accessible for adjustment units without dismantling convertible top parts or the like.
  • the bow 14A is largely designed as a rigid structure.
  • the position of the arc 14A with respect to the drum is therefore determined by the bolts 126, the arc 14A being provided with a predetermined radius of its outer surface 14B.
  • the convertible top elements are attached to this surface, but this is not described here, since it does not play a role in and of itself for the invention.
  • the bow 14A is provided with an end part in the form of an elastically bendable arm 12A.
  • Arm 12A is initially formed with the same radius as the stiff portion of arch 14A, but is then bent inward (biased) such that a tongue carried by arm 12A would strike surface 1A of the drum when attaching arch 14A the countermeasures described below would not have been taken.
  • the bias of the arm 12A is shown in Fig. 9 by the dashed line of the arm 12A. Arm 12A would take up this "dashed position" if it were not prevented from doing so.
  • the striving of the arm 12A inwards is limited by a stop which is formed by the end of an adjusting screw 32.
  • the screw 32 is screwed into a continuous threaded bore, which is provided in the edge portion 121 (see also FIG. 7) of the shield, in such a way that the threaded bore extends radially to the shield 113 between the recess 123 and the aforementioned groove in the Border stretches.
  • the radial position of the stop ie the outer end of the screw 32
  • the tongue is still at the end, i.e. attached to the arm 12A of the arch.
  • the tongue could be fastened using fastening means similar to the screw 40 in FIG. 4.
  • Such a solution would be disadvantageous in combination with the new adjustment because it does not have some advantages of the adjustment itself. Preferred solutions to the task of tongue fastening will therefore be described below with reference to further figures.
  • the adjustment in the embodiment according to FIG. 9 thus differs from the arrangement according to FIG. 4 (ie according to the closest prior art) in that the upper leg 11 of the convertible top segment according to FIG. 4 has been omitted, so that the adjusting screw 32 (FIG 9) cooperates with the shield (instead, according to FIG. 4, only with the convertible top segment). This has made it possible to pass the screw 32 through the edge portion 121 of the shield and to make it accessible from the outside of the shield.
  • the edge portion 121 of the shield comprises the aforementioned groove 130 with the base 131.
  • the arm 12A of the segment 14A now has a bore (not indicated by a reference number) which extends at right angles to the axis of the screw 32 and accommodates an element 140 which in FIG the bore is rotatably mounted about an axis 132.
  • the element 140 comprises, at at least one end, a part 133 which has a cylindrical surface 134, this surface 134 being arranged eccentrically with respect to the axis 132.
  • the tongue 4A is also shown in FIG. 10, this new tongue being formed in the form of a continuous casting profile.
  • the profile 4A is mounted by means of a fastening means 34 (in FIG. 10, a screw 34) on the underside or outside of the end part 12A (of the arm 12A).
  • the screw 34 extends through a bore (unthreaded) in the end portion 12A and is freely rotatable therein.
  • the screw 34 is held on the part 12A by a hood 36, the hood 36 itself being fastened on the end part 12A by a screw 37 such that it fits into the groove 130 during assembly.
  • the hood 36 is provided with an opening 39 to allow access to the screw head, and the bottom 131 of the edge section 121 is provided with a corresponding opening 41 so that access is ensured during operation.
  • the opening 41 can be provided with a closure 35 so that it is not contaminated or even clogged during operation by (e.g.) flight.
  • the arrangement according to FIG. 10 can clearly also be used with the conventional tongue construction.
  • Fig. 11 basically shows the same elements as Fig. 10 and again the same reference numerals have been used where possible.
  • a spring assembly 38 is additionally provided between the head of the screw 34 and the surface of the end section 12A facing it.
  • the contact pressure between the tongue 4A (or 4) and the underside of the section 12A (in particular in the vicinity of the screw 34) is limited by the spring assembly.
  • the pull the screw 34 in the fastening point becomes independent of the tightening torque which is exerted on the screw.
  • This enables the tongue to expand in its longitudinal direction (ie in the direction of the working width of the machine) during operation without deflecting due to distortion from the selected adjustment.
  • Such an expansion of the tongue must be expected, since it is subjected to the entire width of the heated air of the carding area.
  • the present invention is in no way limited to the configuration and assembly versions given only as examples.
  • the tongue 4 has a nose 5, via which (according to EP-A-432430) a more or less large air overflow is to occur in the direction of rotation of the consumer 2.
  • the direction and intensity of the overflowing air could be changed by adjusting the "opening angle" a and by changing the distance A.
  • the same arrangement is provided at both ends of the tongue, so that the gap A below the drum roll can be set as precisely as possible over the entire working width of the reel by means of the two adjustment means.
  • the profile 4A according to FIG. 10 has a head part which has been changed considerably in comparison to the embodiment according to FIGS. 2 and 4. This head part is therefore shown again in FIG. 12 (and also in FIG. 14) to a larger scale and is designated by the reference symbol 50.
  • the head part 50 is provided with a surface 54 which is directed towards the diverging gap S between the drum or the pickup, so that the air or fiber stream flowing out of the gap is deflected by this surface 54.
  • the "decision" is made in the gap S as to whether a fiber which has previously been moved by and with the drum 104 will continue to move with the drum 104 or with the take-off roller 107 (or, if need be, with neither of the two).
  • the peripheral speed of the drum 104 can reach up to approximately ten times the peripheral speed of the doffing device 107 (approximately 40 m / s) and the drum generates a considerable suction effect between itself and its casing in the "closed" space (in the work area). Air is therefore sucked out of the gap S into the working area of the drum 104.
  • the consumer 107 carries relatively little air. A fiber that has not been firmly received by the assembly of the pickup 107 may therefore tend to follow the main flow on the drum 104 or even fall through between the rollers (especially short fibers).
  • the effect of the new tongue 4A will now be explained by a comparison with the effect of the old tongue 4, for which purpose the old tongue shape is also shown in FIG. 12.
  • the respective head sections 50 and 56 are initially compared with one another. Based on the statements in EP-A-432430, it can be expected that an air stream leaving the gap S flows over the surface 58 at the head part 56. Accordingly, the surface 60 facing the gap S is rounded but has an edge-like design, e.g. a radius of the order of magnitude R3 (3 mm). A "sharp" separation of the air flow following the drum from the air flow that should be deflected in the direction of the take-off roller 107 is likely to be achieved in this way.
  • the head section 56 has a triangular shape with a clear (even if rounded) "tip" 60, which is opposite to the diverging gap S.
  • the head section 50 is rather “bulbous” with round (curvilinear) contours (viewed in cross section).
  • the surface 54 which is directed towards the gap S, accordingly has a radius Rx which is selected in the range R4 to R10 (i.e. in the range 4 mm to 10 mm).
  • the preferred range is R6 to R8 (i.e. 6 mm to 8 mm).
  • the surface 54 forms, with the lateral surface M of the drum 104, a funnel-like inlet E into the working gap AS between the guide surface LF of the tongue and the drum 104.
  • the trunk parts 70 and 75 are now compared with one another.
  • the fuselage section 70 of the old tongue 4 is designed as a simple sheet metal part, it has a suitable curvature in order to serve as a covering for the drum 104.
  • the head section 56 is therefore formed with an angled wall 72, which gives it the aforementioned triangular shape and has a sharp (albeit rounded) bend 73 relative to the surface 58.
  • the fuselage section 75 has a surface 76 which (viewed in the direction of the drum 104) appears as a concave (indented) surface.
  • the surface 76 merges smoothly into the contours of the bulbous head part 50 at one end. At the other end, the surface 76 merges into a foot part 78, which adjoins a schematically indicated cladding element 80.
  • This element could e.g. are formed according to US 5,142,742, but could also have a different design.
  • a very important dimension in the carding machine is that of the working gap A on the reel, ie the distance under operating conditions between the drum (base or jacket surface) and the guide surface opposite it for the air or. Fiber flow. It is generally desirable to have the smallest possible distance in order to guide the fiber as close as possible to the clothing.
  • the working gap is normally measured at the point where the air or fiber flow leaves the tongue in order to be "taken over” by the further covering of the drum. This practice is also maintained when comparing the two guiding elements, it should be noted that the length L (FIG. 14) of the tongue 4A is less than half the corresponding length of the old tongue 4, ie with the new tongue 4A the air or fiber flow is transferred to the further cladding earlier.
  • the new tongue 4A allows significantly narrower gap settings A than was possible with the old tongue 4.
  • Examples include a gap of 0.5 mm with the new tongue under working conditions that would have required a gap size of at least 0.8 mm with the old tongue.
  • the narrower setting at the inlet end of the working gap in the sub-carding zone enables the gap width to be narrowed across the entire zone.
  • a gap width of approx. 1 mm can be set at the outlet end AE with the new tongue, where a gap of at least 1.5 mm would be necessary with the old tongue.
  • the reduced column widths in the sub-carding zone result in significantly lower nep values.
  • the surface 76 serves as a guide surface for this flow penetrating into the gap S and, in particular, enables a laminar flow pattern that clings closely to the guide surface 76.
  • the surface 76 shows a further guide element 4B according to the invention, the indentation of the surface 76 relative to the head part 50 having been (almost) eliminated. However, the surface 76 still forms an indentation in relation to the wider foot part 78, the is still adapted in its width B to the adjacent cladding element 80 (FIG. 12, not shown in FIG. 15).
  • the surface 55 has a smaller radius (for example R5 to R6) than the surface 54, which favors the inflow of the air / fiber mixture into the working gap between the surface LF and the drum (not shown).
  • the flows around the guide element 4B are explained below with reference to FIG. 16, where the air flows are shown schematically with arrows.
  • the air flowing out of the wedge gap S is indicated by L in FIG. 16.
  • Most of this flow L continues to flow with the drum i.e. into the "funnel" formed between the reel and surface 55 of the baffle 4B.
  • a relatively small part La continues to flow with the collector 107 (FIG. 12) and the rest LS flows between the collector 107 and the guide element 4B towards the bottom.
  • the guide element 4B it should be achieved that as few good fibers as possible flow away with the flow LS.
  • the formation of fleece on the reel should be as free of disturbances (turbulence) as possible.
  • the negative pressure in the working gap between the drum and the guide element draws air Lz around the head section 50.
  • the flow Lz mixes with the flow Lt in the funnel-like inlet to the working gap. This flow Lz is obtained from air Lr, which flows from the flow Ls on the surface 76 and then along this surface in the direction of the head part 50.
  • the flow Lz sweeps over the head 50 and reduces the tendency of fibers to stick to the surface 54.
