Definitions
- the invention relates to a device for depositing synthetic fibers into a nonwoven according to the preamble of claim 1.
- spunbonded nonwoven synthetic fibers are usually withdrawn by means of a draw-off nozzle to a spinning device and conveyed to a storage belt for storage.
- the guiding and conveying of the fibers is effected by an air flow of the draw-off nozzle, which is taken up and removed by a suction device arranged below the storage belt.
- the ansarrrmelnden on the belt surface of the storage belt fibers result in a nonwoven, which is continuously required by the storage belt.
- the web formation is dependent on the impact of the fibers on the Ablage ⁇ band and the belt speed. In particular, the impact of the fibers can be influenced by changing the air flow.
- DE 37 40 893 A1 discloses a device for depositing synthetic fibers into a nonwoven, in which a plurality of movable stowage flaps are arranged in a guide shaft upstream of the depositing belt, on the one hand the air flow of the exhaust nozzle and, on the other hand, the air flow to affect when hitting the storage belt.
- the guide shaft at the ends facing the storage tape ends each have a pivotally held damper on which relative to the storage belt with afford ⁇ different angles of attack can be maintained.
- the known device has the disadvantage that gaps are formed between the ends of the guide shaft and the storage belt. Such fissures lead to the fact that the suction device in addition to the supplied air flow with a significant proportion of the ambient air with sucks.
- a direct influencing of the fiber support for the formation of the nonwoven takes place. There is a danger of obtaining so-called windings in the fleece.
- Another object of the invention is to provide a device for storing synthetic fibers to form a nonwoven, with which nonwovens with reproducible nonwoven qualities can be produced.
- the storage flap of the guide shaft is formed by a support and an elastic sealing lip, which sealing lip is in sliding contact with the storage belt.
- the invention is characterized in that a seal takes place on the longitudinal side of the guide shaft between the depositing belt and the end of the guide shaft, which shields the depositing area from the surroundings.
- the elasticity of the sealing lip causes a preload which prevents the sealing lip from lifting off or separating when the contact is rubbing.
- unevennesses on the depositing belt can advantageously be compensated by the sealing lip.
- a suction of external air can be avoided.
- the guide shaft on the opposite longitudinal side on a second movably held damper which is formed by a second carrier and a second elastic sealing lip, which sealing lip is held in contact with the web deposited on the depositing belt during operation in grinding contact. It is thus advantageously possible to achieve a high sealing effect against external air intake on the longitudinal side of the guide shaft, at which the nonwoven is guided out of the storage area.
- the deposition of the fibers is thus carried out substantially without Ein ⁇ effect of sucked ambient air.
- the adjustability of the stowage flap is completely preserved relative to the storage belt.
- the carrier will lead with the held elastic sealing lip in different positions relative to the storage belt. Due to the adjustability of the carriers and sealing lips, it is possible to influence the storage angle and the entire storage image of the fibers. So wide or narrow storage areas can be set on the storage belt.
- the sealing lips are aus ⁇ exchangeably connected according to an advantageous development of the invention with the carriers, so that with worn sealing lips corresponding maintenance work can be performed quickly.
- the sealing lips are preferably formed from a thin sheet steel, which rests with its free end on the storage belt or the fleece.
- sealing lips at least in the contact area with wear protection.
- these could be formed by a special coating in the contact area.
- the carrier are pivotally mounted and each of the carrier is associated with an actuator, by which an enclosed between the storage belt and the sealing lip angle of attack is changeable and adjustable. This allows arbitrary and reproducible angles of attack to be set on the guide shaft.
- the flexibility of the adjustability for depositing the fibers can be advantageously further increased by the guide shaft is held by means of a holder under ⁇ half of the trigger nozzle, the opposite in the longitudinal sides holding elements allow a shift and adjustment of the associated shaft elements.
- the influence of the tray can already be done directly on leaving the fibers from the drawing-off nozzle.
- an adjustable infant opening is formed below the storage band, by means of which the suction device is connected to the underside of the storage band.
- the mammalian opening can advantageously be formed between two cover plates which are held displaceably relative to one another, so that the fiber deposit can be made very compact, for example with a narrow mammal opening or fanned out with a corresponding broad mammal opening.
- a suction gap formed between the cover plate and the storage belt has proven to be effective, which allows for a defined suction of foreign air from the areas outside the storage area.
- the suction gap formed between the cover plates and the storage belt is preferably designed to be adjustable, so that the amount of the sucked-in external air can be adapted individually to the process parameters.
- the adjustability can be realized by adjusting the height of the cover plates.
- a plurality of spacers are arranged between the cover plates and the storage belt, which preferably have a semi-circular cross-section to the top band facing the top, so that a support and guidance of the storage belt is guaranteed.
- the suction gap is formed, through which only a defined amount of external air can enter the suction area.
- the suction gap is preferably set in the range of 1 to 1.5 mm.
- the height differences can be realized by replacing the sealing lips or by changing the angle of attack of the jam flaps.
- the device according to the invention is thus characterized by a maximum of flexibility for nonwoven storage.
- the desired setting parameters for the production of a specific fleece can be set.

- the stowage flaps 5.1 and 5.2 are each formed by a support 6.1 and 6.2 and a sealing lip 7.1 and 7.2 interchangeably connected to the support 6.1 and 6.2.
- the carriers 6.1 and 6.2 are each variable via pivot axes 8.1 and 8.2 in an angle. In this case, the angle of attack forms the angle enclosed between the depositing belt 3 and the stowage flap 5.1 to 5.2.
- the sealing lips 7.1 and 7.2 are elastically configured so that a lower end of the sealing lips 7.1 and 7.2 is in sliding contact with the depositing device band 3 or the guided on the ⁇ blageband 3 web 14 is.
- the area of the storage belt 3 within the guide shaft 2 between the sealing lips 7.1 and 7.2 is referred to here as a storage area.
- the storage belt 3 is ver ⁇ connected with a drive device, not shown here, through which the storage belt 3 can be guided in a direction indicated by arrow conveying direction.
- the storage belt 3 is formed permeable to air, so that the air flow of the discharge nozzle 1 penetrates the deposit belt 3.
- a suction device 4 is arranged on the underside of the storage belt 3. In this case, the suction effect of the suction device 4 is limited to the storage area within the guide shaft 2.
- the exemplary embodiment illustrated in FIG. 1 is shown in an operating situation in which the fibers 13 are continuously guided through the draw-off nozzle 1 into the fiber channel 12 and are required to form the deposit belt 3.

- stoppers 5.1 and 5.2 are each assigned actuating means 11, by means of which the angle of attack at the end of the guide shaft 2 can be adjusted and changed. In principle, however, it is also possible to position such movably arranged stowage flaps 5.1 and 5.2 with manual adjusting devices. It is essential that the adjustment takes place via the carriers 6.1 and 6.2.
- the sealing lips 7.1 and 7.2 held on the supports 6.1 and 6.2 are used exclusively for sealing engagement with the deposition belt 3 or the fleece 14.
- a further exemplary embodiment of the device according to the invention for depositing synthetic fibers to a nonwoven fabric is shown schematically in a cross-sectional view.
- the exemplary embodiment according to FIG. 2 is essentially identical to the previous exemplary embodiment, so that only the differences will be explained in the following description.
- a lower storage height is set between the draw-off nozzle 1 and the storage belt 3 in comparison with the preceding embodiment.
- the deduction nozzle 1 is designed to be adjustable in height.
- the guide shaft 2 arranged between the draw-off nozzle 1 and the storage belt 3 is formed in this exemplary embodiment by two mutually opposing storage flaps 5.1 and 5.2.
- the storage flap 5.1 has a carrier 6.1, which is pivotally mounted on the pivot axis 8.1.
- the pivot axis 8.1 is arranged on a holding element 15.1 of the holder 9.
- the bracket 9 is mounted on the outlet side of the exhaust nozzle 1.
- a sealing lip 7.1 is interchangeably fixed, for example in the form of a steel sheet.
- the length of the sealing lip 7.1 is dimensioned der ⁇ art that the lower end of the sealing lip 7.1 in sliding contact with the storage belt 3 is.
- On the support 6.1 engages an actuating means 11.1, through which the carrier 6.1 is pivotable about the pivot axis 8.1.
- the baffle 5.2 is arranged by the carrier 6.2 and the sealing lip 7.2.
- the carrier 6.2 is guided on the pivot axis 8.2, wherein the pivot axis 8.2 is arranged on the holding element 15.2.
- a sealing lip 7.2 is interchangeably fixed, which, with its free end in the grinding contact, is in contact with a fleece 14 guided on the depositing belt 3.
- the sealing lip 7.2 could also be formed as a steel sheet, for example, with a thickness of 0.2 mm.
- On the support 6.2 engages an actuating means 11.2, through which the carrier is pivotable about the pivot axis 8.2 and positionable.
- the holder 9 is formed by the opposing holding elements 15.1 and 15.2.
- the holding elements 15.1 and 15.2 are designed to be horizontally displaceable, so that the guide shaft 2 can be adjusted in its width transversely to the conveying direction of the fibers.
- the length compensation in the guide shaft 2 can be compensated either by replacing the sealing lips 7.1 and 7.2 by correspondingly shorter or longer sealing lips or by changing the angle of attack of the carriers 6.1 and 6.2.
- the suction device 4 has an adjustable infant opening 16, which is assigned directly to the storage area on the storage belt 3.
- the mammal opening 16 is in this case formed between two slidably arranged cover plates 17.1 and 17.2.
- Each of the cover plates 17.1 and 17.2 can be hori move zontal.
- a minimum suction gap 18 is formed between the cover plates 17.1. and 17.2 and the Abla ⁇ band 3.
- the suction gap 18 is so measured be ⁇ that a foreign air outside the storage area on the storage belt 3 is sucked. In particular in the area of the nonwoven guide, it is thus possible to avoid lifting off the nonwoven 14 from the depositing belt 3. An additional suction in the conveying direction of the fleece 14 can thus be dispensed with.
- the suction gap 18 is designed to be adjustable, for example by a height adjustment of the cover plates 17.1 and 17.2.
- the function of the exemplary embodiment illustrated in FIG. 2 is identical to the preceding embodiment example, so that reference can be made to the preceding description. Due to the flexible design of the guide shaft 2, however, a variety of setting options are executable to obtain a special fiber deposit and thus a specific fleece. In this case, the adjusting movements of the holding elements 15.1 and 15.2, the draw-off nozzle 1, the cover plates 17.1 and 17.2 could be carried out automatically by actuators which can be controlled, for example, by a central control device. Thus, it is possible to perform an automatic adjustment of the various actuators depending on predetermined product and process parameters.
- FIGS. 3 to 5 show some variants of operating settings of the device shown in FIG. 2.
- a relatively wide storage area can be realized by the fact that, as shown in FIG. 3, the storage flaps 5.1 and 5.2 are each held pivotably outwardly.
- a correspondingly large suction opening 16 on the bottom side of the storage belt 3 thus leads to a spreading of the fiber during storage, so that a relatively loose fleece is formed.
- FIG. 4 shows an operating setting of the device from FIG. 2, in which the storage flaps 5.1 and 5.2 define a relatively narrow storage area on the storage belt 3, so that a correspondingly small storage area 16 is produced on the storage belt 3.
- the fibers 13 are deposited almost perpendicularly on the depositing belt 3, so that in particular compact and strong nonwovens can be produced.
- FIG. 5 schematically shows a further possibility of setting the operation of the device shown in FIG. 2.
- a relatively wide discharge region is produced on the deposit belt, which is arranged laterally offset from the outlet side of the discharge nozzle.
- the fibers are deposited on the depositing belt 3 at a relatively flat angle.
- the operating settings shown in FIGS. 3 to 5 only show a small bandwidth of the possible setting variants of the device according to the invention. All operating settings of the device according to the invention have in common that the influence of outside air during the deposition of the fibers is reduced to a minimum. Due to the sliding contact between the sealing lips 7.1 and 7.2 to the storage belt 3 and the web 14 a sealing effect is generated, which prevents the intake of foreign air. Thus, the longitudinal sides of the guide shaft 2 are substantially closed to the environment.
- FIG. 6 schematically shows a further exemplary embodiment in a cross-sectional view.
- the embodiment is shown only in a section of the storage belt.
- the components not shown here are identical to the aforementioned embodiments, so that further explanation is unnecessary at this point.
- a plurality of spacers 19 are arranged at a distance from each other.
- the spacers 19 have to the top of the storage tape 3 facing a rounding.
- the spacers 19 are preferably designed with a crescent-shaped cross-section and extend as webs substantially over the entire width of the depositing belt 3.
- the suction gap 18 is in this case formed by the distance between the underside of the spacers 19 and the upper side of the cover plates 17.1 and 17.2. Li Fig. 6, the suction gap 18 by the gap height with the reference symbol S marked.
- the gap height is preferably set to max. 1 mm to 1.5 mm.
- the distance between the spacer 19 is selected below the storage belt 3 such that at least one spacer 19 is disposed on each side of the mammal opening 16.
- the spacers 19 arranged on both sides of the mammal opening 16 are located within the storage area formed by the sealing lips 7.1 and 7.2 resting above the depositing band 3.
- the spacers 19 could also be made exchangeable to adjust different gap heights of the suction gap 18 can.
- the exemplary embodiment of the device according to the invention according to FIG. 6 is thus distinguished in particular in that a small amount of external air from the environment passes into the suction device. Especially on the storage side the suction gaps are chosen such that the external air intake is sufficient to ensure a firm contact of the fleece to the storage belt.
- FIGS. 1 to 6 are exemplary in design and construction of the components.
- the invention thus extends to all similar devices in which the movable shaft walls of a guide shaft are held towards the depositing belt by sealing lips in sliding contact with the depositing belt.
- the exemplary embodiments according to FIGS. 1, 2 and 6 could also be modified in such a way that a shielding of the end sides takes place by additional shielding means.
- Such Abschirrnstoff could thus influence the fleece storage, especially at the Rän ⁇ countries of the storage belt.
- additional extraneous air effects can be achieved.
- Another variant of the device according to the invention could also be realized by an automated actuator control of the stoppers or the cover plates.
- an automated actuator control of the stoppers or the cover plates can be selected quickly and reproducibly in order to obtain optimum operating conditions, depending on the fiber and fleece type.
