Definitions
- the present invention relates to a card or card, with a clothing-equipped roller and at least two carding segments arranged one behind the other at least over a region of the roller circumference and in the direction of rotation, each of which is provided with a tooth set, tooth sets of the carding segments being configured differently.
- Such a card is known for example from DE-OS 2 226 914.
- the carding segments described there have different stocking densities.
- Such devices are used for cleaning, opening and parallelizing raw fibers, e.g. Cotton.
- the starting material (flake shape) is fed via an opening roller unit to a clothing-equipped roller (e.g. drum) and is taken along by it along its circumference in the direction of rotation.
- the roller is equipped with a large number of saw teeth.
- This set of teeth is usually produced by producing a sawtooth wire, which is then unwound on the outer circumference of the roller.
- the tooth shapes can be shaped differently for the most diverse application purposes. However, the tooth tips mainly point in the direction of rotation.
- Carding segments are arranged at least over part of the circumference of the roller so that the fibers are not only carried along by the clothing-equipped roller, but rather that processing is present.
- a carding segment extends across the entire width of the roller.
- the underside of a carding segment is arch-shaped to match the outer circumference of the clothing-equipped roller and also has a tooth set.
- the teeth are arranged in rows of teeth and are also created by inserting a sawtooth wire.
- the tooth shape is similar to the tooth shape on the clothing-equipped roller, the tooth tips pointing counter to the direction of rotation of the clothing-equipped roller.
- the carding segments are moved towards the roller to such an extent that an opening, combing or parallelization process is carried out on the fibers.
- the teeth of the tooth sets have a cutting angle that is at least larger on average in a front carding segment than in a subsequent carding segment, so that the engagement of the tooth set of the front carding segment in the direction of rotation has a greater effect on a circumference the roller has entrained individual fiber as the engagement of the tooth set of a carding segment following in the direction of rotation.
- the tooth sets of the carding segments cause the different machining effects from intensive to less intensive without having to influence other parameters. Due to the dependency on simple geometric relationships, it is very easy and inexpensive to carry out an optimal assembly of carding segments for the most varied types of fibers. A whole series of very different can thus be on the same device, card or card Tooth shapes. are used. It has been shown that this configuration enables very effective fiber processing or processing to be carried out at relatively high speeds and with a very good result. In particular, the tendency of the tooth set due to the tooth geometry to pull fibers away from the roller should be reduced, so that the fibers are optimally conveyed in the processing gap between the carding segment and the roller. A set of teeth that is optimally adapted to the degree of opening of the fibers can be recognized by the uniform wear of the machining height of the teeth.
- a very simple variant of the embodiment of the present invention is that the teeth of the tooth sets have a cutting angle ⁇ which is at least larger on average in a front carding segment than in a subsequent carding segment. Due to the design, the tooth sets have hundreds of teeth in many cases. In most cases, a single comparison of a tooth of a set of teeth of a carding segment with a tooth of a set of teeth of a subsequent carding segment would suffice. For the effect, however, it is completely sufficient if, on average, it emerges that the front carding segment has a more aggressive engagement than the subsequent carding segment. In this respect, an average cutting angle is used.
- the cutting angle ⁇ extends between the rake face or here the fiber processing surface of the tooth and an imaginary line that extends from the tooth tip to the center of the roller extends. This means that the front carding segments act on the fibers at a flatter angle, whereas in the subsequent carding segments the machining surfaces of the teeth are increasingly erect against the fiber.
- the tooth set of the first carding segment tears, pulls or pulls more on the fibers than subsequent carding segments.
- the increasingly smaller angle ⁇ means that the fibers no longer penetrate the tooth area of the tooth set with the intensity or depth. Rather, it is caused that, due to the increasingly dull tooth shape, the fibers no longer tend to penetrate as much into the processing area of the toothing of the carding segments. Tests have shown that this also results in the fibers being better across the entire height of the machining area of the teeth, which is also shown in particular by the wear pattern.
- the Teeth wear out essentially uniformly over their entire height of the machining zone. Neither the tip nor the foot area of the processing zone are subject to greater wear.
- a further possibility of influencing the desired carding effect via the tooth shape is that the teeth of the tooth sets have a surface that lies between the outer cutting area contour line comprising the cutting surface and an imaginary one that perpendicularly cuts the roller axis and the tooth tip Degree of connection is spanned, which is greater at least on average in a front carding segment than in a subsequent carding segment.
- This means that the area below the processing area of the tooth is larger at the beginning of the carding process than afterwards, so that probably more fibers can penetrate into the processing area of the toothing of the carding segments at the beginning than with subsequent carding segments.
- the fibers are pressed more and more towards the roller as the degree of opening increases due to the geometry of the tooth shapes of the carding segments. As a result, the fibers are optimally transported on average in the carding nip between the respective carding segment and the roller. The impact that the teeth of the carding segment have on the fibers is then usually less due to this geometric adaptation.
- a further design measure consists in the teeth of the tooth sets having a cutting area and a foot area and the width of the foot area being greater in a front carding segment than in a subsequent carding segment.
- this variant can be used to arrange the teeth of the different carding segments offset one behind the other.
- a further measure for realizing the invention can consist in that a tooth pitch of the teeth of the tooth sets is larger in a front carding segment than in a subsequent carding segment.
- tooth pitch is understood to mean the distance from one tooth tip to the next tooth tip in the carding direction. This means that with subsequent carding Segments that are closer to each other.
- the teeth of the tooth sets can have a height that is at least larger on average in a front carding segment than in a subsequent carding segment.
- the essential factor is the section height of the teeth of a set of teeth. The lower height in the following carding segments automatically ensures less aggressive intervention, e.g. if the carding segments are set at the same height with respect to the roller.
- a further improvement in the parallelization and processing of the fibers can be achieved in that the teeth or rows of teeth formed by the teeth and extending in the direction of rotation of the set of teeth of a front carding segment offset laterally to the teeth or formed by the teeth in the direction of rotation have extending rows of teeth of the tooth sets of the subsequent carding segment.
- the teeth of a single carding segment can be arranged in a row one behind the other, as seen in the carding or rotating direction of the roller.
- the teeth of the following carding segment should be positioned offset so that the fibers can be processed over the entire width independently of the paths specified by the respective carding segments.
- the result of the width of a tooth of the set of teeth of a front carding segment divided by the width of a tooth of the set of teeth of the subsequent carding segment cannot be an integer. This automatically ensures that it is impossible to arrange the teeth of one after the other front to a subsequent card segment. The teeth must always be offset due to the odd pitch.
- a further embodiment variant are arranged that the arranged teeth of a carding segment in the direction of rotation hinte reinan ⁇ offset.
- dirt separating devices can be arranged at least between some carding segments. These can be designed, for example, according to DE 19852562. This is usually a Leitance which is adjustable in height and acts a following separating blade, the angle voted in be ⁇ on the fiber and removed by the impact effect of dirt particles.
- suction devices or a suction device are advantageously provided, which remove fiber fragments and dirt particles from the carding area. There are sufficient design options for this in the prior art.
- the carding segments of the cover in the tooth sets there have a distance between the shoulder and the tooth tips that is smaller than the distance between the shoulder and the associated tooth tips in the tooth set of the reel.
- the lower lane height formed in this way in the cover sets means that the fibers get out of the cover back onto the drum more quickly.
- the invention relates to a carding segment for a device, such as a card or card, for fiber processing, which is provided with a tooth set.
- the carding segment is characterized in that the tooth geometry of the set of teeth is designed differently in the machining direction and an engagement of an area of the set of teeth in the direction of processing has the same or greater effect on an individual fiber to be processed as or as the engagement of an area subsequent to the machining direction toothed clothing.
- the desired effect can also be achieved within the processing area of the carding segment itself.
- relatively large carding segments would be conceivable, which can bring about this effect overall.
- the change in the tooth geometry within this carding segment can be carried out in the same way as the previous changes, which take place from carding segment to carding segment. It is therefore possible to change the angle, height, etc. within a single carding segment.
- the invention also relates to a method for opening, combing and parallelizing fibers by means of a clothing-equipped roller and at least two carding segments arranged one behind the other at least over a region of the roller circumference and in the direction of rotation, each of which is provided with a tooth set.
- the method is characterized in that as the degree of opening of the fibers progresses, the tooth geometry of the tooth sets of the carding segments is changed as a function of the degree of opening of the fibers, so that the fibers are in engagement substantially uniformly over the entire height of the processing areas of the teeth of the tooth sets of the carding segments.
- the method according to the invention performs a function as a function of the degree of opening of the fibers and the wear on the tooth sets. This in particular also has the effect that the fibers are conveyed and processed optimally in the processing gap between the carding segments and the roller. Tests have shown that very good results can be achieved with improved wear behavior. Why the prior art has always been reversed and the fibers have been processed with greater impact or aggressiveness with increasing degree of opening can only be answered in retrospect on the basis of an obviously misconception.
- FIG. 1 shows a carding device with a plurality of carding segments arranged one behind the other in a schematic side view
- FIG. 3 is a view of a tooth cut from the set of FIG. 2 along the line III-III in FIG. 2,
- FIG. 6 is a schematic illustration to illustrate the offset between the teeth of a front carding segment and a carding segment behind it
- FIG. 7 is a schematic bottom view of a carding segment with oblique rows of teeth
- Fig. 8 is a schematic representation of the tooth set of a single carding segment, which changes in the machining direction, and
- Fig. 9 is a schematic representation of a sectional view through a sawtooth wire of the drum set with a sawtooth wire of a cover gamitur arranged above it.
- FIG. 1 schematically shows a carding device 1 in a plane perpendicular to an axis of rotation A of a carding roller or a reel 2.
- the outer surface 3 of the drum 2 is provided with a clothing 4 for processing fiber material.
- the set 4 consists of coiled toothed wire, the individual teeth pointing with their tips in the direction of rotation or carding direction B.
- the design of such sets 4 is best known in the prior art and will not be described in more detail here.
- the arrow B shows that the drum 2 rotates clockwise.
- An opening roller 5, which feeds the fibers to the drum 2, is shown schematically on the left-hand side. Known opening roller devices can also be used here. There are sufficient examples of this in the prior art.
- On the opposite side there is a take-off roller 6, which stands schematically for the take-off device, which remove the carded fibers from the reel 2 and remove them for further processing. With regard to the take-off devices 6 there are also in the prior art
- each of these carding segments 7 to 10 is arranged at a certain distance above the lateral surface 3 of the reel 2.
- the segments are also adapted to the contour of the reel 2 and therefore run in an arc shape, the underside always being at the same distance from the other Shell surface 3 is arranged.
- these carding segments 7 to 10 are provided with a tooth set 12 to 15. Similar to the set 4 of the reel 2, these tooth sets consist of toothed wire sections arranged side by side. The basic design and arrangement of such sets on carding elements is also known in the prior art.
- Each carding segment 7 to 10 can be regarded as a type of cover piece which is arranged floating at a short distance above the drum 2 and, in contrast to the drum 2, stands still. Accordingly, a processing gap 16 for carding the fibers, not shown, is present between the tooth set 4 of the reel 2 and the tooth sets 12 to 15 of the carding segments 7 to 10.
- a separation channel 17 is provided between each of the carding segments 7 to 10 for removing impurities and fiber fragments.
- an L-shaped, strip-like hold-down device 18 which presses the fibers coming out of the processing gap 16 somewhat downward, so that they then expand explosively outwards and come into contact with a separating knife 19 .
- the discharge knife 19 can assume a wide variety of angular positions, so that the separation can take place with different cutting angles.
- the height of the discharge knife 19 above the tooth set of the reel 2 can also be adjusted.
- the height of the hold-down device 18 is also corresponding to the drum 2 for changing the Distance adjustable.
- FIG. 2 shows a small section of the tooth set of the carding segment 7 in an enlarged representation.
- the tooth set 12 is turned upside down.
- the individual teeth 20 of the tooth set 12, at least as long as they are arranged in a row, are made from a common steel wire.
- 2 shows teeth 20 in the form of a sawtooth profile.
- the Winkelbe ⁇ be drawings and ratios, as usually in cutting tools ver ⁇ be objected here used to describe the toothed clothing 12th
- each tooth 20 has a wedge angle ⁇ and a cutting angle ⁇ .
- the cutting angle ⁇ extends between a tangent to the chip or machining surface 21 and a line 22, the course of which is defined by the shortest connection between the tooth tip 23 and the axis A of the reel 2. These ratios of course apply in incorporating carding 7.
- the wedge angle ß ⁇ is usually less than 45 °, so that relatively sharp teeth are generated 20th
- the distance t between a tooth tip 23 to the next tooth tip 23 of a row of teeth is referred to as tooth pitch in the present case. In most cases, hundreds of these teeth 20 are attached to the underside 11 of a carding element 7 to 10.
- tooth 20 is understood to mean the entire structure shown in FIG. 3 with the height h.
- This tooth 20 is divided into an upper cutting area 25 with the height h s and a lower foot area 26.
- the foot area is rich 26. wider than the cutting area 25, so that when the tooth wires 24 are arranged next to one another, the cutting areas 25 are at a lateral distance from one another.
- the cutting area 25 extends along one side of the tooth wire 24 to the tooth tip 23 and merges essentially seamlessly into the foot area 26, whereas on the other side the transition takes place into the foot area 26 by means of a step 27.
- the foot region 26 has a width F st . Ultimately, this foot width F st also ensures the distance between the cutting areas 25 of a set of teeth.
- the foot region 26 serves to anchor the tooth wires to the underside 11 of the carding segments 7 to 10.
- the tooth pitch t also decreases from carding segment to carding segment in direction B. This means that the tooth pitch t in the carding segment 7 is greater than in the carding segment 8, in the carding segment 8 is larger than in the carding segment 9 and in the carding segment 9 is larger than in the carding segment 10. The distance between the teeth 20 thus becomes smaller from carding segment to carding segment.
- the height h s of the cutting area 25 also decreases in the carding direction B from carding segment to carding segment. Specifically, this means that the height h s in the carding segment 7 is greater than in the carding segment 8, in the carding segment 8 is greater than in the carding segment 9 and in the carding segment 9 is greater than in the carding segment 10. This also reduces the overall height h of the teeth 20 from carding segment to carding segment.
- the overall height h would be maintained and only the height h s of the cutting area 25 would be reduced.
- the above-mentioned reductions in the dimensions for the angle ⁇ , the tooth pitch t, the foot width F st and the cutting area height h s are averaged values in relation to the respective carding segments 7 to 10. This is to ensure that the aggressiveness with which the fibers are processed decreases from carding segment to carding segment. Accordingly, the carding segment 7 works more aggressively than the carding segment 8, the carding segment 8 more aggressively than the carding segment 9 and the carding segment 9 more aggressively than the carding segment 10. Aggressiveness is understood to mean the intensity of the action of the carding segments on the fibers. All of these measures are preferably used in combination. However, it is possible to change just one of these dimensions.
- machining surface 21 spans a contour line in the side view, starting from the tooth tip 23, which is concavely curved in the foot region of the tooth 20.
- This area piece F can be determined for each tooth of the tooth sets 12, 13, 14 and 15. Both when changing the angle and when changing other parameters in accordance with the teaching of this invention, this area piece F is always smaller in a subsequent carding segment than in a previous carding segment. In this context, an average area size of the area F per carding segment 7, 8, 9 or 10 can also be used.
- the volume below the machining surface 21 is also reduced, so that not as many fibers can be accommodated in this area with a decreasing surface size of the surface F. This always leads more open fibers for a more uniform distribution along the processing surface 21 and for a uniform wear.
- Fibers are fed to the drum 2 via the opening roller 5 and are taken along by the toothed set 4 on its lateral surface 3 in the direction of rotation B.
- a combing process takes place to parallelize the fibers. This is due to the fact that the tooth tips 23 of the tooth set 12 of the carding segment 7 point counter to the tooth set 4 of the reel 2.
- the subsequent dirt separation in the discharge channel 17 removes the first fiber fragments and dirt particles.
- the fiber material passes through the working gaps 16 between the carding segments 8 or 9 or 10 and the drum 2, the carding or parallelization of the fibers taking place with decreasing intensity.
- the intensity decreases due to the above-described configuration of the tooth sets 12 to 15 on the carding segments 7 to 10.
- the parallelized ⁇ and entrained fibers are then removed from the drum 2 again via the take-off roller 6 and removed for further processing.
- FIG. 5 shows the undersides of two carding segments 7 and 8 arranged one behind the other. For reasons of simplification, only a part of the tooth sets 12 and 13 is shown.
- toothed wires with a plurality of teeth 20 are used, which run essentially parallel to a plane intersecting the axis A perpendicularly.
- the tooth tips of the teeth 20 point to the left.
- the tooth rows of the carding segment 7 are arranged offset to the tooth rows of the carding segments 8. This is shown in FIG. 6 by means of a schematic front view of the teeth.
- the two front teeth 20 symbolize two rows of teeth of the carding segment 7 arranged next to one another, and the tooth 20 lying between and behind it symbolizes a row of teeth of the carding segment 8 lying behind. It is easy to see that the cutting areas of these teeth 20 are arranged offset from one another, so that each also has different ones Areas of the fibers of the carding segments 7 and 8 are processed. This offset can also be achieved in that the foot width F st of the preceding carding segment 7 divided by the foot width F st of the following carding segment 8 does not result in an integer (F str JF stn + ⁇ ⁇ integer). It can also be seen from FIG.
- all of the dimensions described in the first exemplary embodiment can be changed in order to influence the intensity of the carding effect from carding segment to carding segment.
- FIG. 8 shows schematically that the front teeth 20 in the machining direction have a larger cutting angle 1 than the following teeth.
- the cutting angle 1 is accordingly larger than the cutting angle 2 and the cutting angle ⁇ 2 larger than the cutting angle ⁇ 3. Due to the fact that the cutting angle ⁇ 4 is negative, the cutting angle ⁇ 3 is also larger than the cutting angle 4.
- FIG. 8 is only a schematic illustration, which is why the change in tooth shape can also take place over a larger area and could be carried out more slowly. All other changes in the geometry of the teeth to achieve the same effect could also be carried out in such a carding segment 30 similarly to the changes described above. However, you will probably be able to achieve the best results due to the change in angle. It would be quite conceivable for a single carding segment 30 designed in this way to be arranged on a roller 4.
- the distance h between the shoulder 40 and the associated tooth tips 41 is chosen smaller than the distance H between the shoulder 42 and the associated tooth set of the carding segments. Tooth tips 43 of the drum set.
- the resulting reduced lane height h in the lids means that despite the cutting edges acting more aggressively on the fibers in the first carding segments, which pulls the tufts of fibers from the carding zone between the tooth tips into the lanes of the lid, the fiber volume in the lids is kept low and also the dwell time of the fibers in the carding segments of the cover is reduced.
