Definitions
- the invention relates to a method for depositing a nonwoven or the like. According to the preamble of the main claim and to a nonwoven tape layer according to the preamble of claim 5.
- Such nonwoven tape layers are used, in particular, to lay down nonwovens, fibrous webs, spunbonded fabrics or the like supplied by a card or the like onto a removal belt that is moving at a predetermined variable speed.
- the nonwoven fabric fed by the card is transported on a feed belt driven at a predetermined speed.
- the nonwoven fabric is usually at least partially transported between two conveyor belts which move at the same speed.
- These conveyor belts are designed as endless conveyor belts. In order to deposit the fiber fleece as evenly as possible, such fleece belt layers require carriages in which deflection rollers for the conveyor belts are mounted.
- the sudden speed changes of the wagons can cause an irregular warping of the nonwoven fabric, namely because of the time-adjusted adjustment of the wagon and belt speeds due to the springing up of the frame and the working elements.
- the fleece cannot follow the conveyor belts immediately.
- 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 carriages can thus be changed at will via their travel path, the acceleration phases in the reversal points of the travel movement also being able to be influenced as desired.
- the exit speed of the nonwoven always corresponds to the nonwoven 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 with delay at laying speeds below the tape inlet speed (positive distortion) and also with compression at laying speeds above the tape inlet speed (negative delay) can be filed.
- the features of the main claim and of claim 5 serve to solve this problem.
- the laying carriage speed can be set to a higher or lower speed relative to the infeed speed of the fleece in order to achieve a jamming or stretching of the fleece when it is deposited. 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 to 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 and must be accelerated again from there, with even a specific dilution of the fleece is accessible in the edge area, which is advantageous for subsequent processing.
- 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.
- the two drives for the uppercarriage and laying carriage travel are controlled by a computer. It is possible to deposit the pile without distortion, compression or stretching, 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 tensioning carriage is brought into its respective position by the force 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 via the difference in circumferential speeds on these deflecting rollers.
- Another exemplary embodiment consists of providing an electronically controlled linear drive for the uppercarriage and the laying carriage and for 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.
- FIG. 1 shows a schematic diagram of the coupling according to the invention between the superstructure, the tensioning carriage, and the laying carriage and the drives;
- FIG. 3 shows a second exemplary embodiment of the invention with a tensioning carriage consisting of two carriage parts and an additional intermediate carriage;
- FIG. 4 shows a third exemplary embodiment of the invention with a modified tape guide
- the nonwoven belt layer 1 (FIG. 2) has a feed belt 2, via which a pile or nonwoven 4 or the like is transferred from a card arranged in front with a uniform However, a variable speed of, for example, 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 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 have the fleece 4 between them pick up, transport and guide.
- 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 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 one, which is mounted in a feed-side machine stand 54a Conveyor belt 18.
- the redirection 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 deflecting 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 54a is again deflected by 180 ° and fed to the reciprocating tensioning carriage 12, via the deflection roller 36 supported on the tensioning carriage the first conveyor belt is ultimately fed back to the first deflection roller 24.
- 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 stored in the laying carriage 14, the second deflection roller 44 together with the deflection roller 30 of the laying carriage at the exit point 46 of the fleece 4, the fleece again for the last time between the two conveyor belts 18 , 20 leads.
- 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 for driving the uppercarriage, the tensioning carriage and the laying carriage, the ends of which are anchored in place on 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 sprockets 62, 64 each provided with an electronically controlled drive, also deflected by 180 °.
- the drive chain 52 thus becomes from the fastening 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 chain wheel 60 of the laying carriage 14 is again guided to the second fastening 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 enable a completely independent control of the movement of the laying carriage and the movement of the uppercarriage.
- FIG. 3 shows an exemplary embodiment of a nonwoven belt layer with a divided tensioning carriage 12, which consists of two carriage parts 11, 13, the deflecting roller 36 for the first conveyor belt 18 being mounted in the carriage part 11, while at a distance from the carriage part 11 arranged carriage part 13, a deflection roller 49 for the second conveyor belt 20 is mounted.
- a connection is provided between the two car parts 11, 13.
- the superstructure 10 is arranged, in which the belt guide of the second conveyor belt 20 is changed as follows in relation to FIG.
- the second conveyor belt 20 passes from the deflection roller 38 of the uppercarriage 10 via one to that of the deflection roller 28 opposite end of a reciprocating intermediate carriage 16 mounted deflection roller 39 directly to the deflection roller 44 of the laying carriage 14.
- the laying carriage 14 now only has a single deflection drum for the second conveyor belt, which in the return via the stationary deflection rolls 48 , 50 and the deflecting roller 49 of the carriage part 13 and a further stationary deflecting roller 51 mounted in the machine stand 56 are fed back to the deflecting roller 38 of the uppercarriage 10.
- a further conveyor belt 21 is provided for the intermediate carriage 16, which instead of the second conveyor belt 20 in the embodiment of FIG. 2 clamps and transports the fleece between itself 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 as a function of 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 two deflection rollers 26 ′, 26 ′′, 38 ′, 38 ′′ each take place, the fleece 4 being between the deflection rollers 26 '' and 38 '' is passed through with a smaller radius.
- the inlet zone in front of the two deflecting rollers 26 ′′ and 38 ′′ there is therefore a large opening angle between the two conveyor belts 18 and 20, which in the exemplary embodiment is over 90 °.
- this opening angle can also be only 20 ° with the position of the rollers 26 'and 26' 'unchanged, or can be variably adjustable.
- the fleece 4 is fed in an arcuate or polygonal shape to the stationary deflection roller 28, the diameter of which is enlarged in comparison to the exemplary embodiment in FIG. 2.
- a guide roller 41 is mounted above the exit point 46, which guides the second conveyor belt 20.
- the conveyor belt 20 and the conveyor belt 21 are preferably driven only by friction, but they can also be driven by coupling to the conveyor belt 18 or can be provided with their own drive.
- the chain guide in the chain wheel 62 differs from FIGS. 2 and 3 in that two additional guide wheels 61, 63 are arranged in front of and behind the chain wheel 62.
- the sprockets 62 and 64 and the deflection roller 24 are provided in the exemplary embodiments shown in FIGS. 2 to 4 with suitable rotary encoders in order to transmit speed signals to the electronic control.
- a synchronous belt or the like can of course also be used.
- FIGS. 2 to 4 the laying width and the center of the laying width are identified by a dash-dotted line.
- the reversal points for the laying carriage travel are determined by the electronic control, by driving the chain wheel 64 accordingly.
- FIGS. 5a, 5b, 5c show the paths covered by the superstructure 10, the tensioning carriage 12 and the laying carriage 14 with respect to the center of the laying width.
- the minus values indicate a movement in the direction of the machine stand 54a on the feed side. From the figures it can be seen that the tensioning carriage moves back and forth only about half the laying width compared to the laying carriage.
- the superstructure also only moves back and forth about half the laying width, but offset by a certain distance in relation to the middle of the laying width.
- the laying carriage approaches the turning points at a reduced speed, while the tensioning carriage is moved uniformly in the direction of movement on the feed-side machine stand 54a over the entire travel path. Only the return begins and ends with a slowed phase.
- 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. Fig. 6b represents the peripheral speed of the fleece 4
- FIGS. 6c, 6d and 6e each show the speed profile of the uppercarriage 10, the tensioning carriage 12 and the laying carriage 14.
- the maximum speed of the laying cycle reached after the acceleration and braking phases 0 carriage 14 can be set higher than the running-in speed of the fleece 4.
- FIGS. 5 and 6 show path and speed diagrams without taking into account a set delay.
- the tensioning carriage 12 serves to tension the conveyor belt required for the additional pile storage.
- the belt speed of the first conveyor belt 18 or the peripheral speed of the deflection roller is 24 V. This speed is preferably constant and remains unchanged for the forward and reverse travel of the laying carriage.
- the laying carriage speed in position B is composed of the belt speed V minus or plus speed components, which take into account a predetermined warping which 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 with the aid of the chain wheel 64 via an electronic control which controls the laying carriage speed as a function of the desired warping or warping course, the laying width, the braking and acceleration phases, etc.
- the superstructure speed in position C is controlled via the sprocket 62 according to the following relationship:
- V Q 1/2 x (V E - (K + 1) / K x V L ),
- the exit speed V of the fleece 4 is dependent on the belt speed V as well as 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 nonwoven and the average warpage factor.
- V Sp "(V L + V '
- the speeds in positions B, G, C and H are determined by electronic controls, while the speeds in positions D, E, F 0 and K inevitably result from the mechanical dependency.
- Fig. 7 shows the fleece 4 deposited on the discharge belt 6 in profile. 5
- the edge area is not thickened but specifically thinned.
- the edge area is thinned desirable because the edges often become thicker as a result of the further processing and thereby create a compensation.
- Another 'drive variant be ⁇ teht is a Ver ⁇ train directly by controlling the Ge ⁇ chwindtechnik de ⁇ conveyor belt 18 at the points E and F set.
- the deflecting rollers 28 and 32 or 34 are driven in an electronically controlled manner.
- a cable pull takes the place of 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.
