Definitions

  • the invention relates to a method for operating a storage table for a fleece layer with a layer that deposits a folded fibrous web on a discharge belt, the storage table having an endless belt that takes over the folded fibrous web from the discharge belt at a pulsating speed and at a constant speed to a subsequent machine for further processing or consolidation of the folded fibrous web.
  • carding systems with subsequent nonwoven layers are usually used.
  • fiber tufts are fed in on the inlet side, which are dissolved down to the individual fibers and output on the outlet side as an unconsolidated textile fabric, the fibrous web.
  • the batt layer which can be designed as a table layer or steep arm layer, transports the fibrous web to an outfeed belt arranged at 90° to the infeed direction and places the fibrous web in a predetermined laying width in several layers on the outfeed belt.
  • the fleece that is then created can be solidified in a subsequent needling machine.
  • the relation between the infeed speed of the web layer and the outfeed speed of the outfeed belt determines the layering to be achieved, i.e. the number of layers of fiber web in the flat structure "fleece" to be delivered.
  • the continuously incoming fibrous web is deposited on the outfeed belt, which is arranged at 90° to the infeed direction of the fibrous web the fleece layer is extended.
  • the corresponding relation between the infeed speed of the fibrous web into the fleece layer and the corresponding outfeed speed of the outfeed belt results in the appropriate web thickness for the structural properties of the incoming fibrous web and thus determines the structural properties of the stacked individual webs.
  • the increasing use of fleece layers in production lines with a low fleece weight leads to high delivery speeds and low layer counts. In extreme cases, only 4 layers are placed on the delivery table, the discharge belt. In connection with the required material throughput, larger card working widths are increasingly being used. Both factors, number of layers and roller working width, lead to an S-shaped looping of the laid web due to the braking and acceleration distances of the oscillating laying carriage at a uniformly constant speed of the take-off belt.
  • S-shaped looping means that the pile layers in the edge area of the laid fleece are not straight, but in the form of crooked paths.
  • the take-off table is also decelerated and accelerated again synchronously with the movement of the laying carriage.
  • the machines arranged behind the web layer such as the web draw frame or needling machine, require a constant feed speed of the web.
  • so-called storage tables are used, which are arranged between the take-off table and the downstream machine.
  • the fleece is fed onto the storage table synchronously with the pulsating speed of the take-off table, whereas the fleece is discharged from the storage table into the downstream machine at a constant speed.
  • the WO2014/037503 A1 describes a compensating device in which an endless belt is guided around at least four deflection rollers.
  • the compensating device is arranged between a stacker and a needling machine.
  • a first deflection roller is coupled mechanically or in terms of drive technology to the speed of the delivery belt of the stacker.
  • the speed of the first deflection roller leads to a pulsating up and down movement of the endless belt, since the driven second deflection roller continuously feeds the web into the needling machine. It is provided that a compensating device tightens the lower run of the endless belt.
  • EP 1897979 A2 discloses a leveling device located behind a crosslapper and having a lower take-up belt and an upper cover belt.
  • the belts are deflected several times so that the fleece is guided between them.
  • the deflection rollers are kept at the same distance by a horizontally movable carriage. Since the belts move at different speeds, the fleece is compressed, which is not desired.
  • a drafting device arranged between the pile producer and the piler through which the pile entering the stacker is stretched or compressed in a targeted manner, with the aim of obtaining a fleece with a specified profile at the output of the piler.
  • the stacker is followed by a compensating device to which the fleece is transferred.
  • This consists of an endlessly circulating storage belt, the upper strand of which conveys the fleece has a variable sag.
  • the storage belt is guided around a deflection roller on the take-off table of the stacker, which is coupled to the stacker, i.e. it runs unevenly.
  • this deflection roller Parallel to the first deflection roller associated with the stacker, there is another deflection roller for the storage tape at a distance therefrom arranged.
  • the drive of this deflection roller runs constantly at the speed of the further processing, so that the web runs at a uniform speed in a subsequent further processing.
  • the object of the invention to create a method for operating a storage table for a fleece layer, with which a continuous feeding of the fleece into a subsequent machine is made possible at high speeds of the fleece layer.
  • the aim is to have as little distortion as possible on the folded fibrous web and to transfer it to the downstream machine with a high level of quality.
  • the storage table comprises an endless belt which takes over the folded fibrous web from the outlet belt at a pulsating speed and delivers it at a constant speed to a downstream machine for further processing or consolidation of the folded fibrous web.
  • the endless belt of the storage table is driven by a first drive at the inlet and by a second drive at the outlet, the first drive being coupled to the movement and the speed profile of the layer. Coupling does not mean the level of speed, but the control of the drive to the movement or corner points of the layer, which accelerates in its back and forth movement, moves constantly and brakes in the opposite direction.
  • the drive at the entrance of the storage table is synchronized with the movement of the layer, so that the storage table can be operated independently of the speed of the outfeed table.
  • the folded fiber web has the same speed on the outfeed belt as on the infeed of the storage table, i.e. a pulsating speed that fluctuates between the minimum value of, for example, 0 m/s and a maximum value with the disadvantage that the cross-laid fiber web can lift off the belt due to the continuously decreasing or increasing sag of the upper run of the storage table.
  • the drives of the outfeed belt and the deflection roller, which together with the belt determines the speed of the infeed of the storage table, are coupled with one another in such a way that both belts always run at the same speed.
  • the outfeed belt and the belt at the infeed of the storage table have a speed that constantly fluctuates between standstill and a maximum value at the same time and in height, which means that there is constant acceleration or deceleration. Undesirable creases and visible defects arise when the folded fibrous web lifts off the belt in the area of the slack.
  • the speed of the outfeed belt is decoupled from the infeed speed of the storage table at the deflection roller.
  • the drive of the outfeed belt is decoupled from the drive of the deflection roller, so that they have an unequal speed.
  • it is planned to couple the drive of the infeed on the storage table to the movement and the speed profile of the layer.
  • the movement or corner points of the layer are relevant, which accelerates in its back and forth movement, drives constantly and brakes in the opposite direction, not the level of the speed of the layer.
  • the coupling of the drive at the storage table infeed to the movement profile of the layer ensures more precise control of the speed of the storage table and reduces distortion on the folded fiber batt.
  • the speed of the storage infeed at the deflection roller no longer goes back to the minimum value of the outfeed table, for example 0 m/s, but is always positive. This means that the belt is always moving at the infeed of the storage table and is not slowed down to zero and then accelerated to a maximum value. Due to the reduced difference in speed between the infeed and outfeed of the storage table, the pulsating sag of the belt is reduced so that the folded fiber batt no longer lifts off the belt.
  • the belt of the storage table forms a slack in the upper strand to compensate for the speed differences between the inlet and the outlet of the storage table, in which the fiber batt is temporarily stored.
  • the speed of the fibrous web at the inlet of the storage table is always greater than the speed of the fibrous web at the outlet of the layer and at the same time the maximum speed of the folded fibrous web at the inlet of the storage table is lower than the maximum speed on the outfeed belt.
  • a further improvement is that the minimum speed of the infeed at the storage table is between 30% and 70% of the maximum speed at the outfeed belt.
  • the folded fibrous web is thus moved more continuously on the belt between the outfeed belt and the subsequent bonding machine, so that only a slight draft acts on it.
  • the principle of a web layer in the embodiment of a table or stacker 1 is shown as an example and only schematically.
  • a steep arm stacker could also pick up and set down the web.
  • the fibrous web 3 is transported onto an infeed belt 2 of a stacker 1 by a carding system, not shown.
  • An upper carriage is arranged inside the stacker 1, in which only one deflection roller 6 can be seen in this illustration.
  • the stacker 1 has a laying carriage, of which a laying roller 10 for a counter belt 13 and a laying roller 9 for the infeed belt 2 are shown.
  • the so-called laying gap 11 is arranged between the laying roller 10 of the counter-belt 13 and the laying roller 9 of the infeed belt 2, from which the fibrous web 3 exits and is deposited on an outfeed belt 15 arranged below the laying carriage.
  • both laying rollers 9, 10 take on the task of depositing the fibrous web 3 orthogonally to the previous running direction onto an outlet belt 15 arranged below the laying carriage and folding it in the process.
  • the laying carriage continuously moves back and forth in the horizontal direction over a preset width, the so-called laying width.
  • the laying carriage is thus constantly accelerated and decelerated with the fleece.
  • the outfeed belt 15 also has a pulsating speed.
  • the infeed belt 2 is deflected around a first and second deflection roller 4, 5, around a deflection roller 6 of the upper carriage and around deflection rollers in the laying carriage, e.g.
  • a cover belt 7 can be arranged above the infeed belt 2 and, in this illustration, is guided around a deflection roller 8 , a deflection roller 6 of the superstructure and a further deflection roller 12 .
  • Other design variants, in which the laying carriage does not interact with the infeed belt 2 but with another belt, are possible and known.
  • the infeed belt 2 and the cover belt 7 do not run parallel, but rather form an acute angle open towards the carding machine, in which the fibrous web 3 is drawn in and slightly compressed.
  • the fibrous web 3 is guided around the deflection roller 6 of the superstructure, with the shroud 7 being discharged laterally by means of the deflection roller 12 .
  • the fibrous web 3 is transported in exactly the other direction, since it is guided around the deflection roller 6 of the superstructure by 180° and is deposited on a counter-belt 13 arranged parallel below the infeed belt 2 .
  • the counter-belt 13 and the infeed belt 2 now clamp or guide the fibrous web 3 together up to the laying gap 11, which is essentially formed by the distance between the two laying rollers 9 and 10 of the laying carriage.
  • the fibrous web 3 emerges from the laying gap 11 and is placed on a discharge belt 15 arranged below the laying gap 11 .
  • the laying carriage thus moves continuously in a horizontal reciprocating direction (direction of the arrow) over the width of the outlet belt 15 or over the set laying width, on which the fibrous web 3 is laid and folded in the process.
  • the infeed belt 2, the shroud 7 and the counter-belt 13 can be designed as endless belts, with the shroud 7 and the counter-belt 13 being able to be designed to be air-permeable in order to discharge entrained air.
  • An inexpensive embodiment is the use of a perforated tape.
  • a preferred embodiment is the use of a screen belt.
  • the laying carriage speed can be increased or decreased relative to the infeed speed of the fibrous web. That is, the laying rollers 9 and 10 move faster or slower in the horizontal reciprocating direction.
  • Both the infeed belt 2 and the cover belt 7 have the same running direction for the fibrous web 3 and usually the same speed. To a certain extent, the fiber orientation at the surface in relation to the neutral fiber of the sliver can be influenced if both belts 2, 7 are run at slightly different speeds.
  • FIG figure 3 shows the rear part of the outlet belt 15, from which the folded fiber web 3 is transferred to the storage table 20.
  • the endless outfeed belt 15 is tensioned by at least two deflection rollers 16, of which at least one deflection roller 16 is driven.
  • the result for the folded fibrous web 3 on the outfeed belt 15 is the speed v 15 , which can pulsate between the value 0 m/s and a maximum value of 0.11 m/s due to the back and forth movement of the laying carriage can.
  • Downstream of the outfeed belt 15 is the storage table 20.
  • the storage table 20 comprises an endless belt 21 which is guided and tensioned by a plurality of deflection rollers 22, 23, 24.
  • At least the pulleys 22 and 23 are driven, wherein the deflection roller 22 is associated with the outlet belt 15, and the deflection roller 23 of the subsequent compacting machine, not shown.
  • Another deflection roller 24 can be arranged in the upper run between the driven deflection rollers 22, 23, so that with a speed difference between the deflection rollers 22 and 23, the belt 21 in the upper run can form a slack 25 between the deflection rollers 22 and 24, with which the different speed of the folded batt 3 can be compensated and equalized.
  • the belt 21 is arranged approximately horizontally in the upper run between the deflection rollers 24 and 23 in order to let the folded fiber batt run horizontally into a subsequent nonwoven section.
  • the deflection roller 24 can be dispensed with in a downstream needling machine.
  • the deflection roller 22 which forms the inlet of the storage table 20 with the belt 21 and is arranged close to the outlet belt 15, the folded fiber web 3 has the speed v 22 .
  • the fibrous web In the area of the upper strand between the deflection rollers 24 and 23, the fibrous web has the constant speed v 23 .
  • the folded fiber web 3 has the same speed on the outlet belt 15 with v 15 as on the inlet v 22 of the storage table 20, i.e. a pulsating speed that fluctuates between the minimum value 0 m/s and a maximum value with the disadvantage that the cross-laid fibrous web 3 can lift off the band 21 due to the sag 25 that is permanently decreasing or increasing in the process.
  • the outlet belt 15 and the belt 21 at the inlet of the storage table 20 have a speed that is permanent fluctuates between standstill and a maximum value, resulting in constant acceleration or deceleration.
  • the lifting of the folded fibrous web 3 from the belt 21 in the area of the sag 25 results in undesirable creases and visible defects.
  • the speed of the outfeed belt 15 is decoupled from the infeed speed of the storage table 20 at the deflection roller 22 .
  • the drive of the outfeed belt 15, for example the drive of the deflection roller 16, is decoupled from the drive of the deflection roller 22, so that they can have different speeds.
  • v 15 ⁇ v 22 v 15 ⁇ v 22 .
  • the speed v 22 of the storage inlet at the deflection roller 22 no longer returns to the minimum value of the outlet belt, for example 0 m/s, but is always greater.
  • the band 21 always remains in motion at the inlet of the storage table 20 and is not decelerated to zero in order to then be accelerated to a maximum value.
  • the pulsating sag 25 of the belt 21 decreases, so that the folded batt 3 no longer lifts off the belt 21 .
  • the maximum speed of the inlet at the storage table 20 is preferably lower than the maximum speed of the outlet belt 15. This also allows the acceleration and deceleration at the inlet of the storage table 20 to be reduced, so that the forces acting on the transported folded fiber web 3 are lower.
  • the folded fibrous web 3 moved continuously between the outfeed belt 15 and the following compacting machine on the belt 21.
  • figure 4 shows an example of a speed diagram according to the invention for a movement cycle of the laying carriage according to the figures 1 and 2 is essentially formed from the laying rollers 9 and 10.
  • the time in seconds is entered on the abscissa, which can be, for example, 5.4 seconds for a reciprocating cycle of the laying carriage at the speed v 9/10 .
  • the speed v 9/10 of the laying carriage and the speed v 6 of the superstructure which after the figures 1 and 2 is essentially represented by the deflection roller of the superstructure 6, can be read on the right ordinate.
  • the maximum speed v 9/10 of the laying carriage is twice as high as the maximum speed v 6 of the superstructure.
  • the left ordinate which is plotted on a scale twice that of the right ordinate, indicates the outfeed conveyor speed v 15 and the storage table speeds v 22 and v 23 .
  • the speed v 15 of the outfeed belt 15 varies between 0 m/s and 0.11 m/s.
  • the folded fibrous web is thus constantly accelerated and decelerated between a maximum value and a standstill.
  • the speed v 22 at the inlet of the storage table 20 fluctuates only between a value of 0.05 m/s and 0.105 m/s. This means that the inlet of the storage table 20 is operated with a weakened pulsation, which means that the speed v 22 at the reversal points is lower than at the outlet belt 15. Due to the lower acceleration values at the inlet of the storage table 20, lower forces act on the folded fiber web than after state-of-the-art, whereby the quality produced in the web layer is retained.
  • the speed v 23 at the outlet of the storage table is constant at 0.1 m/s.
  • the difference in the speed v 22 at the inlet of the storage table 20 to the speed v 23 at the outlet of the storage table 20 essentially indicates the size of the sag 25, which is significantly smaller here than in the prior art. As a result, the folded fibrous web 3 can be prevented from being lifted off the belt 21 .
  • the speed v 22 at the infeed of the storage table 20 is decoupled from the speed v 15 of the outfeed belt 15, but the movement of both belts must still run synchronously, the speed v 22 of the infeed of the storage table 20 is coupled to the movement and the speed profile of the laying carriage.
  • the starting point for a movement cycle of the infeed of the storage table with the speed v 22 is always when the speed v 9/10 of the laying carriage is zero.
  • the end point of the acceleration or deceleration of the infeed of the storage table always coincides with the end point of the acceleration or deceleration of the laying carriage.
  • the movement of the infeed of the storage table is thus synchronized with the movement of the laying carriage, which means that decoupling from the speed of the outfeed conveyor is possible.
