Definitions
- the invention relates to a device in the form of an arrangement of rollers, in particular embossing rollers and at least one conveyor belt in the form of a transfer belt for nonwoven production, in particular the airlaid production.
- Airlaid production is to be understood as meaning the production of nonwoven, nonwoven fiber products having fiber lengths of up to 50 millimeters.
- the fiber webs are made of natural or synthetic fibers of different material and different staple length.
- a binder such as latex may be provided, for example.
- the bond can also be achieved by partially melting and fusing the fibers together.
- the nonwoven fabric to be produced - including the intermediate product - can be multi-layered. In order to give the nonwoven fabric to be produced a particularly high liquid absorption capacity, the nonwoven fabric can be used superabsorbent polymers in particulate (SAP) or fiber (SAF) form.
- Suitable natural fibers are, for example, cellulose fibers of cotton, hemp, flax or loosened, already mechanically and / or chemically treated wood cellulose (Fluff PuIp).
- Suitable synthetic fibers, in particular the binding of the nonwoven serving synthetic matrix fibers may contain, for example, polyester, polypropylene or viscose.
- Particularly suitable synthetic binding fibers are so-called bicomponent fibers which have a core of a first material, which is surrounded by a sheath made of a plastic, for example polyethylene, which allows fusion of the fibers mitein ⁇ and with natural and matrix fibers.
- the bandwidth of the desired density of the product depends strongly on the final product for which the nonwoven fabric is to be used.
- the bandwidth of the desired fiber fleece density is thus very high.
- the bandwidth of the material to be processed (see above) as well as the Bandbrei ⁇ te the staple lengths of the individual fibers is very large.
- the production of an air-laid fibrous web of the type concerned here usually involves mixing the fibers in a forming head, which is arranged above a forming belt in the form of an air-permeable conveyor belt and deposits the processed mixed fibers as evenly as possible on the forming belt. Below the forming belt suction boxes are arranged, with which the fibers deposited on the forming belt are sucked onto the forming belt.
- the forming head in the direction of the forming belt also known as forming wire
- a compressor roller acts from above on the fiber-air mixture deposited on the forming belt and precompresses this mixture.
- air is pressed out of the fiber-air mixture, so that the thickness of the mixture decreases and its density increases.
- the thus pre-compressed fiber-air mixture is then transferred from a forming belt to a transfer belt, which is arranged above the pre-compressed fiber-air mixture and permeable to air, so that the fiber-air mixture Mixture is sucked from below by means of a suction belt arranged above the transfer belt to the transfer belt and removed from the forming belt.
- the transfer belt serves to supply the pre-compressed fiber-air mixture of the roller arrangement of interest here for the further compression of the fiber-air mixture to form a nonwoven.
- the roller assembly of interest serves to compress the fiber-air mixture as far as possible and in a preferred embodiment by heating the fiber-air mixture a fusion of individual fibers to effect - with possibly simultaneously desired imprinting a structure - which is a nonwoven fabric as an intermediate desired properties arises.
- the device concerned here should be suitable for the production of a wide range of products which may differ considerably in their composition as described at the outset and which accordingly also require a different treatment.
- the amount of heat required to fuse the fibers depending on the composition of the fiber-air mixture as well as the desired thickness and density of réellemateri ⁇ as very different.
- the fiber-air mixture supplied by the transfer belt remains as possible in tact and processed evenly, in particular further compressed.
- a problem in this context, for example, is that the air to be squeezed out of the fiber-air mixture during the compression must escape against the transport direction. In the worst case, an air cushion is formed, which even leads to undesirable wrinkling in the nonwoven fabric.
- a roller arrangement which comprises four rollers each with rotation axes aligned approximately parallel to each other.
- a first of these four rollers serves as a deflection roller for a transfer belt.
- a second roller is arranged below the first roller and forms together with this a first pair of rollers arranged one above the other.
- a third roller is arranged behind the second roller in the direction of the transfer belt, and a fourth roller is arranged behind the first roller when viewed in the direction of travel of the transfer belt.
- the rolls are displaceably arranged relative to one another transversely to their axis of rotation, so that a roll gap for the treatment of a nonwoven fabric can optionally be adjusted between the second and third rolls or between the third and fourth rolls, so that in the first case the second and the third roller form a roller pair arranged next to one another and connect a roller gap for a substantially vertical non-woven transport, while in the second case the third and the fourth roller arranged above form a second roller pair arranged one above the other (next to the first roller roller) one above the other arranged Walzen ⁇ pair in the form of the first and second roller) and include a nip for a substantially horizontal non-woven transport between them.
- the invention is based on the idea of enabling the widest possible range of products to be produced by means of a special design of the roller arrangement arranged immediately downstream of the transfer belt. It has been found that the chosen approach, particularly to design this roll arrangement in particular, is particularly promising compared to alternative approaches, such as the provision of further roll arrangements further from the transfer belt.
- the roller arrangement according to the invention makes it possible to set a different transport path, depending on the type of nonwoven fabric to be produced, namely a transport path between the first and second rollers and then the second and third rollers or a transport path between the first and second rollers and subsequently between the third and fourth roller through.
- the pair of rollers connected downstream of the first superimposed pair of rollers is thus either a pair of rollers arranged side by side (substantially horizontally) or a pair of rollers (substantially vertical) arranged one above the other. In this way, alternatively, the specific advantages of one or the other roller assembly can be used.
- An advantage of the first-mentioned transport path is that the nonwoven fabric is supported by the second roller over a relatively large circumferential angle of, for example, 90 °.
- this makes it possible to efficiently hold a loose nonwoven fabric for producing a product having a low tear strength of, for example, up to 5 N / 50 mm according to EDANA Recommended Test Method "Tensile Strength" 20.2-89 , a large area for the heat transfer from the second roll to the web.
- the alternative, second-named transport route is useful if the fleece delivered by the first pair of rolls arranged on top of one another is sufficiently strong so that no pronounced support of this fiber fleece is required.
- the advantage of the second-mentioned transport path is then that an escape of air during the compression of the nonwoven fabric in the second stacked roller pair formed by the third and fourth rollers is easily possible. The risk of wrinkling is lower overall.
- air nozzles for pressurized or suction air can be provided below or above the transport path between the first and the second pair of rollers arranged above one another, which can generate an upwardly directed air flow over the entire width of the transport path in order to support or guide or guide the loose nonwoven fabric on the second transport path between the first and second superimposed roller pairs.
- the respective pairs of rollers assume the function of such roller pairs in these configurations, which are also referred to as embosser.
- roller pairs make it possible to dispense with a compressor roller downstream of the forming head, as mentioned above.
- the roll gap formed between two rolls of a pair of rolls is preferably adjustable in various respects.
- each one of the rollers of a pair of rollers allows a small relative inclination of the axis of rotation relative to the axis of rotation of the respective other roller of the respective pair of rollers, so that there is a nip, which is closed close in the middle of the rollers or a higher pressure than in the respective longitudinal ends of the rollers.
- the third roller is designed as a deflection-controllable roller or as a roller with variable crowning or bondering.
- a deflection-controllable roll known per se makes it possible, in particular, to produce uniform line pressure over the entire web width of the fibrous web. Under line pressure is understood here to be the course of the pressing pressure in the longitudinal direction of the nip parallel to the axes of rotation of the rollers.
- the third roller is designed as a deflection-controllable roller, it is advantageous if the direction of the lateral deflection can be adjusted so that the deflection can be set either in a horizontal plane or in a vertical plane.
- a deflection in the horizontal direction is desirable when the third roller cooperates with the second roller as juxtaposed roller pair, while a deflection in the vertical direction it is desirable if the third roller cooperates with the fourth roller as a second pair of rollers arranged above one another.
- the latter is between 0 and 150 N / mm, preferably between 0.01 and 100 N / mm. Since it is a skilledn ⁇ pressure, the dimension is length and not area related.
- the distance between the axis of rotation of the first roller and the axis of rotation of the second roller is preferably adjustable by the first roller being displaceable transversely to the axis of rotation in a preferably substantially vertical plane. Since the first roller also serves as a deflection roller for the transfer belt, it may be advantageous if the plane within which the first roller is transversely displaceable is slightly inclined relative to the vertical such that an at least partial equalization of the belt length takes place when the first roller is displaced ,
- transversely displaceable is meant here a continuous displacement of a roller transversely to the orientation of the respective axis of rotation.
- the third roller is arranged so as to be transversely displaceable with respect to the second roller, so that the distance between the two axes of rotation is different or a corresponding line pressure between the second and third Can set roller in the desired manner, when the second and third rollers cooperate as juxtaposed roller pair.
- the third roller is preferably transversely displaceable in an essentially horizontal plane.
- the fourth roller is arranged transversely displaceable in a preferably at least approximately vertical plane, so that the Set the distance of the fourth roller of the third roller or the line pressure between these two rollers in the configuration in which the third and the fourth roller menam act together as a second pair of rollers arranged one above the other.
- the third roller which is transversely displaceable in the horizontal plane, is preferably brought into a position in which the third roller has a greater distance from the second roller than in the configuration in which the second and third rollers are arranged as a side-by-side (horizontal) roller.
- All of the four rolls can be designed as smooth rolls with a smooth shell surface.
- the mantle surface is preferably formed in each case by a jacket made of metal, preferably steel.
- individual ones of the rolls may be formed as embossing rolls and correspondingly have a mantle surface which is provided with depressions or elevations corresponding to the desired embossing pattern.
- only one of the two rolls of a pair of rolls is regularly formed as an embossing roll, while the respective other roll serves as a counter roll.
- the respective counter-roller may have a plastic surface instead of a metallic surface, which is formed by a plastic coating on a metallic roller body.
- the elevations of the embossing rollers cause the nonwoven to be compacted in the area of the elevations of the embossing rollers to be compressed more strongly than in the areas lying between them.
- the fibers are fused together, particularly in the areas which are predetermined by the elevations of the embossing roll.
- the elevations of the embossing rollers preferably have a uniform pattern, for example in the form of a nub pattern, which causes a punctiform compression of the nonwoven fabric.
- Other surface structures of the embossing roller may, for example, consist of diamond-shaped depressions of the mantle surface with webs lying between them.
- the second and / or the fourth roller are preferably used, so that accordingly the first roller and the third roller are designed as smooth rollers or as plastic-coated mating rollers.
- the first roller is preferably designed as a roller with an elastic mantle surface (rubber roller).
- rollers preferably in particular the second, the third and / or the fourth roller may be heatable, so that they allow a heat input into each located with the corresponding roller in contact nonwoven fabric.
- the already mentioned at the beginning of thermal fibers of the fibers by fusing individual plastic fibers together and with natural and matrix fibers can be effected.
- a transport belt for receiving and transporting the fiber web treated by the roller arrangement is preferably provided for the roller arrangement described, which accommodates the fiber web either in the case of the first transport path underneath the roller gap formed by the second and third rollers or in the case of second mentioned Transportwe ⁇ ges seen in the transport direction behind the nip formed by the third and fourth roller.
- the conveyor belt can have a belt section rising in the transport direction, which receives the fiber web below the roll gap formed by the second and third rolls with a vertical conveying direction.
- the conveyor belt may take two alternative configurations, namely the aforesaid configuration and, alternatively, a configuration in which a guide roller of the conveyor belt is located immediately behind the third roller when viewed in the direction of transport when the third roller together with the fourth roller has a second one superimposed pair of rollers forms, so that in this case by the second Walz ⁇ gap with a horizontal conveying direction promoted nonwoven fabric on the shortest paths and preferably on the same horizontal plane as the second nip reaches the conveyor belt.
- Figure 1 is a schematic side view of a section of an apparatus for producing non-woven, non-woven fiber products.
- Figure 2 a section of the device of Figure 1 and schematically per ⁇ speculative representation.
- FIG. 1 The schematic representation of a part of a device 10 for producing nonwoven nonwoven fiber products shown in FIG. 1 serves to explain the part of fiber product production of interest here.
- the conveying direction is as indicated by arrows substantially from right to left.
- a mixture of fibers - possibly of various types - to be processed by the device 10 and possible further constituents of the desired nonwoven fabric are fed in already metered form to a forming head 12.
- the Form ⁇ head 12 serves to achieve the highest possible degree of separation of the fibers and as uniform as possible distribution of the fibers and possible other Vlies ⁇ components on a forming belt or forming wire 14.
- the forming belt 14 is formed like a sieve and therefore permeable to air. It transports the fibers deposited as uniformly as possible on the forming belt 14 as a fiber-air mixture in the transport direction indicated by the arrow from right to left. The fibers or the fiber-air mixture is thereby sucked against the forming belt 14 by a suction box 16 arranged below the forming belt 14.
- the suction box 16 is thus open at the top and provided with a connection 18 for sucking off air.
- a Verdichtungs ⁇ roller 20 may be provided which serves to precompress the fiber-air mixture on the forming belt 14 in which a part of the air is displaced from the fiber-air mixture.
- a transfer belt 22 is arranged just above the forming belt 14.
- the transfer belt 22 is similar to the forming belt 14 formed like a sieve and serves to take over the fiber-air mixture from the forming belt 14.
- a second suction box 24 is arranged above the transfer belt 22, which makes it possible to transport the fiber-air mixture by means of the transfer belt 22 quasi overhead.
- the transfer belt 22 conveys the fiber-air mixture to a four-roller 26, 28, 30 and 32 having roller assembly, of which a first roller 26 also serves as a deflection roller for the transfer belt 22 and together with a disposed below the first roller 26 second roller 28 forms a first, über ⁇ each other arranged roller pair.
- the first, superimposed pair of rollers 26, 28 forms between them a first nip with a horizontal conveying direction, in which the fiber-air mixture is further compressed.
- the nip formed by the first superimposed pair of rollers 26, 28 is adjustable with regard to the gap width or with respect to the line pressure prevailing in the nip.
- the first roller 26 is arranged adjustable in at least an ⁇ approximately vertical direction.
- the first roller 26, which serves as a deflection roller, is preferably designed as a roller with an elastic mantle surface (rubber roller).
- the second roller 28 can then be designed as an embossing roller with a smooth or structured steel surface.
- the Walzenanord ⁇ tion 26, 28, 30 and 32 offers two alternatives.
- a first transport path is shown in FIG. 1 by a dashed line and leads from the first nip between the second roller 28 and the third roller 30 to a conveyor belt 34.
- the second roller 28 and the third roller 30 together form a juxtaposed roller pair which encloses a rolling gap with a vertical conveying direction between them.
- this first transport path is that the fiber-air mixture emerging from the first roll nip is supported relatively over a large area over an angular range of approximately 90 ° by the mantle surface of the second roller 28. This is particularly advantageous in fiber-air mixtures with low tear strength.
- the second roller 28 can be heated. In this case results from the relatively large contact surface of the fiber-air mixture on the second roller 28 in the case of the first transport path, a large area for a Wär ⁇ meübergang of the second roller 28 to the fiber-air mixture.
- the fiber-air mixture is further compressed and then deposited on a rising portion of the conveyor belt 34.
- the fiber-air mixture is preferably guided around the third transport roller 30 in a large angular range, so that another due to large
- the third roller 30 is thus preferably also heatable.
- the third roller 30 can also be designed as a deflection-controllable roller.
- a certain deflection of the axis of rotation can be set, in order in this way to set a corresponding roller gap or a corresponding course of the line pressure. Due to the bearing of a roller in the region of its two longitudinal ends is in such rolls, which are not deflection controlled due to the linear pressure caused bending moments a deflection of the axis of rotation, which results in a nip, which widest in the middle of the roller between the camps is.
- At least one of the rolls of a pair of rollers instead of deflection controlled also be performed crowned, that is, have a from the longitudinal ends to the center increasing diameter.
- the mantle surface thus shows a slightly curved contour.
- Such crowned or cambered rolls are thus an alternative to deflection-controllable rolls, in order to achieve a roll gap of consistently the same width even at a relatively high line pressure.
- the deflection-controllable roller in this case should permit a deflection in a horizontal plane as shown in FIG is shown broken.
- the second layer may be formed as an embossing roll having a structured jacket surface which has corresponding elevations or depressions.
- the fiber fleece is then compressed more strongly, which, with simultaneous introduction of heat, results in the fleece being more densely compressed and more strongly bonded in the more compressed areas.
- a second, alternative transport path is shown in phantom in FIG.
- the fourth roller may be formed as an embossing roller and have a different structure of the mantle surface than, for example, the second roller 28.
- the third roller 30 is designed as a deflection-controllable roller. Since in this case the third roller 30 and the fourth roller 32 form a pair of rollers arranged one above the other, the plane of deflection of the axis of rotation of the third roller is preferably oriented vertically.
- roller arrangement with the rollers 26, 28, 30 and 32 should alternatively allow the first and the second transport path, it is advantageous if the plane of the deflection in the case of a deflection-controllable third roller 30 is selectively adjustable so that this plane is horizontal (first Transport path) or vertically (second transport route) is oriented.
- the fourth roller 32 can also be heated.
- the third roller 30 is mounted horizontally, with respect to its axis of rotation, so as to be transversely displaceable. In this way, the third roller 30 can be moved away from the second roller 28, when the third roller 30 together with the fourth roller 32 is to form a stacked roller pair. In this case, the second and third rollers are unlikely to mesh with each other due to the rotational sense then required for the third roller.
- air nozzles may be provided below or above the transport path between the first superimposed pair of rollers 26, 28 and the second pair of rollers 32, 30 arranged one above the other, over the entire width of the transport path can produce sufficient air flow to support that loose nonwoven fabric on the second transport path between the first stacked roller pair 26, 28 and the second superposed roller pair 32, 30.
- Such a horizontal displaceability of the third roller also makes it possible to set a suitable roller gap or line pressure between the second roller 28 and the third roller 30, if they cooperate in the case of the first transport path as a pair of rollers arranged next to one another.
- the fourth roller 32 is preferably transversely displaceable in the vertical direction with respect to its axis of rotation in order to set the nip in the case where the third and fourth rollers cooperate as a second pair of rollers arranged above each other (second transport path).
- the conveyor belt 34 can also be designed reconfigurable, so that an upper deflecting roller 36 can be brought close to the third roller 30 when the second transport path is selected. For this purpose, it will usually be necessary to move a lower guide roller 38 for the conveyor belt 34, so that the conveyor belt 34 does not touch the third roller 30 and remains tensioned at the same time. Since the rising belt section of the conveyor belt 34 in this case, for example, runs vertically, it would not be suitable for receiving fiber fleece below a roll gap formed between the second roller 28 and the third roller 30, if the first transport path is selected. Therefore, it is advantageous if the course of the transport belt 34 can be reconfigured between two configurations.
