Definitions

  • the invention relates to a pile layer according to the preamble of the main claim and a method for producing a nonwoven according to the preamble of claim 16.
  • Such fleece tape or pile layers are used, in particular, to lay down nonwovens, fibrous webs, spunbonded fabrics or the like supplied by a card or the like on an outfeed belt moved at a predetermined variable speed.
  • the pile fed by the card is transported on a feed belt driven at a predetermined speed.
  • the pile is usually transported at least partially between two conveyor belts that move at the same speed.
  • These conveyor belts are designed as endless conveyor belts. To lay the pile as evenly as possible, such pile layers require carriages in which deflection rollers for the conveyor belts are stored.
  • a nonwoven belt layer is known in which the uppercarriage and the laying carriage have a common or separate drive which moves the carriages at different speeds in the opposite direction.
  • the uppercarriage always runs at half the speed of the laying carriage and covers half the distance of the laying carriage.
  • the drive is designed as a servo drive and connected to a freely programmable control. The speed of the cars can thus be changed as desired via their route, the acceleration phases in the reversal points of the travel movement being able to be influenced as desired.
  • the exit speed of the fleece always corresponds to the fleece inlet speed.
  • the invention is based on the object of designing a method for depositing nonwoven tapes or the like and a nonwoven tape layer in such a way that the nonwoven also has a delay (positive delay) at laying speeds below the belt infeed speed and also a compression (negative delay) at laying speeds above the belt infeed speed can be filed.
  • the laying carriage speed can be set to a higher or lower speed relative to the running-in speed of the fleece in order to compress or stretch the fleece when it is laid down. Intermediate values or non-uniform warping or upsetting over the laying width can also be set. In extreme cases, it is also possible to change the fleece exit speed on the laying carriage towards zero. It is important here that the fleece can be deposited with delay even at laying speeds below the strip inlet speed and also with compression at laying speeds above the strip inlet speed.
  • the invention advantageously makes it possible to work with a delay even in the reversal areas in which the laying speed of the laying carriage has to be reduced to zero up to the reversal point and from there must be accelerated again, with even a specific thinning of the fleece in the edge area is achievable, which is advantageous for subsequent processing processes.
  • the coupling of the uppercarriage, the laying carriage and the tensioning carriage via a single force transmission element in connection with two drives acting on the force transmission element advantageously makes it possible to control the movement of the uppercarriage and the laying carriage independently of one another.
  • warpage (or compression) for example of ⁇ 15%, can be set smoothly.
  • the two drives for the uppercarriage and laying carriage travel are controlled by a computer. It is possible to lay the pile without warping, compressed or stretched, depending on the specification, with speed differences between the belt speed and the laying carriage speed.
  • the tensioning carriage always keeps the main conveyor belt tensioned.
  • the tension carriage is brought into its respective position by the power transmission element and therefore does not require a separate drive.
  • a deflection roller arranged in front of and behind the laying carriage is driven for the main conveyor belt.
  • a delay can be set directly on the difference in the peripheral speeds on these deflection rollers.
  • Another exemplary embodiment consists of providing an electronically controlled linear drive for the superstructure and the laying carriage and coupling the uppercarriage, the laying carriage and the tensioning carriage to one another via a single force transmission element.
  • the tensioning carriage consists of two carriage parts arranged at a distance from one another, in each of which a deflection roller for one of the conveyor belts is mounted.
  • One or more intermediate carriages are arranged between the uppercarriage and the laying carriage. These intermediate cars have the The advantage of distributing the decelerations and accelerations over several machine elements.
  • the nonwoven tape layer 1 (FIG. 2) has a feed belt 2, via which a pile or nonwoven 4 or the like of a card arranged in front of it with a uniform but variable speed of 1.5 m / s is supplied.
  • a discharge belt 6 is arranged transversely to the conveying direction of the feed belt 2 on deflecting rollers 8, on which is deposited transversely and in a zigzag to the delivery direction.
  • a discharge belt 6 running longitudinally, ie also in the same direction as the feed belt 2 can also be provided.
  • the fleece belt layer 1 is equipped with three carriages, namely with an upper carriage 10, a tensioning carriage 12 and a laying carriage 14.
  • the fleece belt layer 1 is provided with two endless conveyor belts 18 and 20 which at least partially absorb, transport and transport the fleece 4 between them to lead.
  • the first conveyor belt 18 takes over the fleece 4 from the feed belt 2 in the area of the fleece inlet 22.
  • a deflection roller 24 is provided at this point, which can simultaneously accommodate the belt drive for the first conveyor belt 18.
  • the belt speed of the conveyor belt 18 is predetermined by the card.
  • the conveyor belt 18 first arrives at a deflection roller 26 which is mounted in the to-and-fro uppercarriage 10 and which deflects the conveyor belt 18 by 180 ° and returns it in parallel to a stationary deflection roller 28 for the first conveyor belt 18 which is mounted in a feed-side machine stand 54a
  • the renewed deflection by 180 ° then leads the conveyor belt to the reciprocating laying carriage 14, which is moved back and forth over the set laying width.
  • the laying carriage 14 is provided with a deflection roller 30 for the first conveyor belt, from where the first conveyor belt 18 runs back to the fleece inlet 22.
  • the conveyor belt 18 is moved over at least one stationary, eg Deflection roller 32, 34 mounted in the machine stand 54 a is again deflected by 180 ° and fed to the back and forth tensioning carriage 12.
  • the first conveyor belt is ultimately fed back to the first deflecting roller 24 via the deflecting roller 36 mounted on the tensioning carriage.
  • the second conveyor belt 20 which rotates endlessly at the same speed as the first conveyor belt, is deflected via a deflection roller 38 mounted on the superstructure 10 such that the fleece 4 fed from the fleece inlet 22 is guided and transported between the deflection roller 26 and the deflection roller 38 of the superstructure .
  • the conveyor belt 20 is deflected in the same direction as the first conveyor belt 18 by the deflection roller 26, so that the fleece 4 between the two conveyor belts 18 and 20 around the deflection roller 28 is guided up to the deflection roller 30 of the laying carriage.
  • the conveyor belt 20 is deflected twice via two deflection rollers 42, 44 mounted in the laying carriage 14, the second deflection roller 44 together with the deflection roller 30 of the laying carriage guiding the fleece again at the exit point 46 of the fleece 4 for the last time between the two conveyor belts 18, 20.
  • the return of the conveyor belt 20 to the deflection roller 38 of the uppercarriage then takes place in a manner similar to that of the conveyor belt 18 via at least one stationary deflection roller 48, 50.
  • a drive chain 52 is provided, the ends of which are fixedly anchored to the machine stand 54b.
  • the drive chain 52 is deflected by 180 ° on each carriage via a sprocket 56, 58, 60.
  • the drive chain 52 of two chain wheels 62, 64 each provided with an electronically controlled drive, also deflected by 180 °.
  • the drive chain 52 thus becomes from the attachment point on the machine stand 54b via the sprocket 56 of the superstructure 10 to the sprocket 62 of the drive motor for the uppercarriage, then via the sprocket 58 of the tensioning carriage 12 to the sprocket 64 of the drive for the laying carriage 14 and the sprocket 60 of the laying carriage 14 again led to the second attachment point on the machine stand 54b.
  • the restoring movement of the upper carriage 10, the tensioning carriage 12 and the laying carriage 14 is effected, for example, with a suitable endless conveyor belt, namely the conveyor belt 18.
  • a suitable endless conveyor belt namely the conveyor belt 18.
  • the position of the superstructure can consequently be determined, while the sprocket 64 determines the position of the laying carriage.
  • the position of the tension carriage 12 results from the movement of the two chain wheels 62 and 64, so that the tension carriage does not require its own drive.
  • the two sprockets 62 and 64 in connection with the tensioning carriage 12 allow a completely independent control of the movement of the laying carriage and the movement of the uppercarriage.
  • 4 warping and upsetting for example in the range between ⁇ 15%, can be adjusted continuously and smoothly when the fleece is laid down, also variable over the entire laying width.
  • Fig. 3 shows an embodiment of a nonwoven belt layer with a divided tension carriage 12, which consists of two carriage parts 11, 13, the deflection roller 36 for the first conveyor belt 18 being mounted in the carriage part 11, while in the carriage part 11 which is arranged at a distance from the carriage part 13 a deflection roller 49 for the second conveyor belt 20 is mounted.

  • the laying carriage 14 has only a single deflection drum for the second conveyor belt, which in the return via the stationary deflection rollers 48, 50 and the deflection drum 49 of the carriage part 13 and a further stationary deflection roller 51 mounted in the machine stand 56 is fed back to the deflection roller 38 of the superstructure 10.
  • a further conveyor belt 21 is provided for the intermediate carriage 16, which instead of the second conveyor belt 20 in the exemplary embodiment in FIG. 2 clamps and transports the fleece between it and the first conveyor belt 18 and guides it over the deflection roller 28.
  • a further deflecting roller 29 is arranged at the end opposite the deflecting roller 28, but still in front of the deflecting roller 39.
  • the intermediate car 16 is provided with a tension chain 31 which is deflected at the ends of the intermediate car 16 via chain wheels 25, 27.
  • the tension chain is fastened on the one hand to the laying carriage 14 and on the other hand to the superstructure 10. In this way, the position of the reciprocating intermediate carriage 16 is determined depending on the movements of the upper carriage 10 and the laying carriage 14.
  • FIG. 4 A third exemplary embodiment of the nonwoven band layer 1 is shown in FIG. 4, the basic band guide corresponding to the exemplary embodiment of FIG. 2.
  • the deflection roller 26 for the first conveyor belt in the superstructure 10 and the deflection roller 38 for the second conveyor belt 20 in the superstructure 10 there are two deflection rollers 26 ', 26' ', 38', 38 '', the fleece 4 between the deflection rollers 26 ' 'and 38' 'is passed with a smaller radius.

  • FIGS. 6a to 6c show the corresponding speed diagrams. From Fig. 6a it can be seen that the inlet speed of the fleece 4 is constant. 6b shows the circumferential speed of the sprocket 62 for the superstructure 10. FIGS. 6c, 6d and 6e each show the speed profile of the superstructure 10, the tensioning carriage 12 and the laying carriage 14.

  • the laying carriage speed in position B is made up of the belt speed V E minus or plus speed components, which take into account a predefined delay that may vary over the laying width.
  • the warping can be positive and then cause the fleece to stretch or be negative and produce a compression, that is to say a thickening of the pile.
  • the laying carriage speed is determined by means of the chain wheel 64 via an electronic control which controls the laying carriage speed depending on the desired warping or warping course, the laying width, the braking and acceleration phases, etc.
  • the exit speed V A of the fleece 4 is dependent on the belt speed V E and on the superstructure speed and the laying carriage speed.
  • the average laying carriage speed corresponds to the product of the running-in speed of the fleece and the average warping factor.
  • Fig. 7 shows the fleece 4 deposited on the discharge belt 6 in profile.
  • Fig. 7a illustrates the so-called bathtub effect in the fleece storage, which occurs in conventional fleece tape layers by slowing the laying carriage in the edge area.
  • the edge area is not thickened but deliberately thinned.
  • the thinning of the border area is desirable because the edges often become thicker as a result of the further processing, thereby creating a balance.
  • Another drive variant is to set a delay directly by controlling the speed of the conveyor belt 18 at points E and F.
  • the deflecting rollers 28 and 32 or 34 are driven in an electronically controlled manner.
  • a cable pull replaces the drive chain 52, the movement of the upper carriage of the tensioning carriage 12 and the laying carriage 14 resulting solely from the drive of the conveyor belt 18.
