Definitions

  • the invention relates to a storage table for a nonwoven with a Leger, which deposits a Felt folded on a discharge belt, wherein the storage table has an endless belt that takes over the folded batt at a pulsating speed of the discharge belt and at a constant speed to a subsequent machine for further processing or solidification of the folded fibrous web, according to the preamble of claim 1, and a method for operating a storage table.
  • carding machines For the production of multi-ply webs usually carding machines are used with subsequent nonwoven layers.
  • fiber flocks are fed on the inlet side, which are dissolved up to the individual fiber and output on the outlet side as an unconsolidated textile fabric, the batt.
  • the fleece layer which may be designed as a Tafelleger or Steilarmleger transports the batt on a 90 ° to the inlet direction arranged outlet belt and sets the batt in a predetermined laying width in several layers on the outlet belt.
  • the resulting nonwoven fabric can be solidified in a subsequent needle machine.
  • the relation of the infeed speed of the web laying machine to the outfeed speed of the outfeed web determines the stratification to be achieved, that is to say the number of layers of web in the web to be delivered "fleece”.
  • the continuously tapered fiber pile opens deposited the outlet belt arranged at 90 ° to the FIB, wherein in the outflow direction an increasing fabric "fleece" is extended from the FAB.
  • S-shaped slurrying means that the pile layers in the edge region of the laid nonwoven are not straight, but in the form of crooked paths.
  • the trigger table is also slowed down and accelerated again synchronously with the carriage carriage movement.
  • the machines arranged behind the fleece layer such as nonwoven web or needling machine, require a constant feeding speed of the fleece.
  • so-called storage tables are used which are arranged between the draw-off table and the following machine.
  • the inlet of the web on the storage table is therefore synchronous to the pulsating speed of the draw table, where against the outlet of the web from the storage table in the following machine at a constant speed.
  • a delay device arranged between pile producer and nonwoven layer is known, by means of which the pile entering the stacker is purposefully stretched or compressed, with the aim of obtaining a nonwoven with an intended profile at the exit of the stacker.
  • the leveler a balancing device is arranged downstream, to which the web is transferred.
  • This consists of an endlessly circulating storage belt, the nonwoven promotional top strand has a variable sag.
  • the storage tape is led to the take-off table of the cross stacker to a guide roller, which is coupled to the stacker, so runs accordingly non-uniform.
  • Parallel to the stacker associated first deflecting a further deflecting roller for the storage tape is arranged at a distance therefrom.
  • the drive of this guide roller runs constantly at the speed of further processing, so that the web runs at a uniform speed in a subsequent processing.
  • the storage table comprises an endless belt which takes over the folded fiber web from the discharge belt at a pulsating speed and delivers it at a constant speed to a subsequent machine for further processing or solidification of the folded fiber web.
  • the invention is characterized in that the endless belt of the storage table is driven at the inlet with a first drive and is driven at the outlet with a second drive, wherein the first drive is coupled to the movement and the speed profile of the leger. Coupling does not understand the height of the speed, but controls the drive to the movement or corner points of the leger, which accelerates in its reciprocating, constantly drives and decelerates in the opposite direction.
  • the drive at the entrance of the storage table is synchronized with the movement of the storage, so that the storage table can be operated independently of the speed of the discharge table.
  • the folded batt on the discharge belt at the same speed as on the inlet of the storage table ie a pulsating speed which varies between the minimum value of, for example, 0 m / s and a maximum with the disadvantage that the cross-laid fibrous web can be lifted off the belt by permanently reducing or increasing the sag of the upper run of the storage table.
  • the drives of the outlet belt and the guide roller, which determines the speed of the inlet of the storage table together with the tape, are coupled together so that both bands always with the same Drive speed.
  • the discharge belt and the belt at the inlet of the storage table have a speed that fluctuates at the same time and in height permanently between standstill and a maximum value, which is constantly accelerated or decelerated.
  • the speed of the discharge belt is decoupled from the speed of the inlet of the storage table to the deflection roller.
  • the drive of the outlet belt is decoupled from the drive of the deflection roller, so that they have an uneven speed.
  • it is provided to couple the drive of the inlet to the storage table to the movement and the speed profile of the leader.
  • the movement or corner points of the leger are relevant, which accelerates in his back and forth, constantly drives and decelerates in the opposite direction, not the height of the speed of the Legers.
  • the coupling of the drive at the storage table inlet to the movement profile of the leger ensures a more accurate control of the speed of the storage table and reduces the distortion on the folded batt.
  • the speed of the storage inlet at the deflection roller no longer goes back to the minimum value of the outlet table, for example 0 m / s, but is always positive. This keeps the tape moving at the inlet of the memory table and will not decelerate to zero before being accelerated to a maximum. Due to the reduced speed difference between the inlet and outlet of the storage table, the pulsating slack of the belt is reduced, so that the folded batt is no longer lifted off the belt.
  • the band of the storage table to compensate for the differences in speed between the inlet and the outlet of the storage table in the upper run a slack in which the batt is cached.
  • the maximum speed of the inlet to the storage table is lower than the maximum speed of the discharge belt. Also, this can reduce the acceleration and deceleration at the inlet of the storage table so that the forces acting on the transported folded batt are smaller.
  • a further improvement is achieved in that the minimum speed of the inlet to the storage table is between 30% to 70% of the maximum speed at the outlet conveyor.
  • the inventive method provides that the batt is deposited folded by a Leger of the web laying on a discharge belt and is transported from there to a storage table with an endless belt that takes over the folded batt at a pulsating speed of the discharge belt and at a constant speed to the subsequent machine for further processing or solidification.
  • the transport speed of the folded fibrous web at the inlet of the storage table is coupled to the movement and the speed profile of the leger.
  • the speed of the discharge belt is from the Speed of the inlet of the storage table decoupled.
  • FIGS. 1 and 2 is exemplary and only schematically illustrated the principle of a nonwoven layer in the embodiment of a table or funnellegers 1.
  • a Steilarmleger could pick up the fleece and drop.
  • the batt 3 is transported to an infeed conveyor 2 of a cross-stacker 1.
  • an upper carriage is arranged, in which in this illustration only one guide roller 6 can be seen.
  • 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 inlet belt 2 are shown.
  • the so-called laying gap 11 is arranged, from which the batt 3 exits and is deposited on a arranged below the laying carriage discharge belt 15.
  • Both laying rollers 9, 10 assume the direction of travel depending on the task to store the batt 3 orthogonal to the previous direction on a arranged below the laying carriage outlet conveyor 15 and thereby fold.
  • the laying carriage moves in a horizontal direction permanently back and forth over a preset width, the so-called laying width.
  • the laying carriage is thus permanently accelerated and decelerated with the fleece.
  • for a curve-free storage especially at low number of layers and the outlet belt 15 have a pulsating speed.
  • the infeed belt 2 is in this embodiment about a first and second guide roller 4, 5, about a guide roller 6 of the superstructure and to guide rollers in the laying carriage, e.g. deflected around the laying roller 9.
  • a shroud 7 may be arranged, which is guided in this illustration to a guide roller 8, a guide roller 6 of the upper carriage and a further guide roller 12.
  • Other structural variants in which the laying carriage does not cooperate with the infeed belt 2 but with a further belt are possible and known.
  • the infeed belt 2 and the shroud 7 do not run parallel in this exemplary embodiment, but form an acute angle open to the carding machine, in which the fiber web 3 is pulled in and slightly compressed.
  • the batt 3 is guided around the guide roller 6 of the upper carriage, wherein the shroud 7 is discharged laterally by means of the guide roller 12.
  • the opposing belt 13 and the infeed belt 2 cling or guide the fiber web 3 together now to the laying nip 11, which is formed essentially from the distance between the two laying rollers 9 and 10 of the laying carriage.
  • the batt 3 emerges from the laying nip 11 and is laid on a discharge belt 15 arranged below the laying nip 11.
  • the laying carriage thus moves permanently in a horizontal reciprocating direction (arrow direction) over the width of the outlet conveyor 15 or over the set laying width on which the batt 3 is deposited and thereby folded.
  • the infeed belt 2, the shroud 7 and the counter belt 13 can be designed as endless belts, wherein the shroud 7 and the counter belt 13 may be designed to be permeable to air in order to remove entrained air.
  • An inexpensive embodiment is the use of a perforated tape.
  • a preferred embodiment is the use of a screen belt.
  • the carriage carriage speed can be increased or decreased relative to the entry speed of the batt. That is, the laying rollers 9 and 10 move in a horizontal reciprocating direction faster or slower.
  • Both the inlet belt 2 as well as the shroud 7 have the same direction for the batt 3 and usually the same speed. To a certain extent, the fiber orientation at the surface can be affected in relation to the neutral fiber of the sliver if both belts 2, 7 are operated at slightly different speeds.
  • FIG. 3 shows the rear part of the discharge belt 15, from which the folded fiber web 3 is transferred to the storage table 20.
  • the endless discharge belt 15 is tensioned by at least two deflection rollers 16, of which at least one deflection roller 16 is driven. This results in the folded fiber pile 3 on the outlet belt 15, the speed vi5, which can pulsate due to the reciprocating movement of the laying carriage between the value 0 m / s and a maximum value, which may be, for example 0.11 m / s , Downstream of the outlet conveyor 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 guide roller 22 is associated with the outlet belt 15, and the guide roller 23 of the following solidifying machine, not shown.
  • a further deflection roller 24 may be arranged in the upper strand, so that with a difference in speed between the guide rollers 22 and 23, the belt 21 in the upper strand can form a slack 25 between the guide rollers 22 and 24, with the different speed the folded batt 3 can be compensated and leveled.
  • the band 21 in the upper run between the deflection rollers 24 and 23 is arranged approximately horizontally, to allow the folded batt horizontally run into a subsequent nonwoven web. In a subsequent needle machine can be dispensed with the guide roller 24.

  • the batt has the constant speed v 23 .
  • the folded batt 3 has on the discharge belt 15 with v 15 the same speed as on the inlet v 22 of the storage table 20, ie a pulsating speed which varies between the minimum value 0 m / s and a maximum value with the disadvantage that the cross-laid batt 3 can be lifted off the belt 21 by the sag 25, which is permanently decreasing or increasing in size.
  • the outlet conveyor 15 and the belt 21 at the inlet of the storage table 20 have a speed that is permanent between standstill and a maximum value, which constantly accelerates or decelerates.

  • the belt 21 at the inlet of the storage table 20 always remains in motion and is not decelerated to zero, and then accelerated to a maximum.
  • the pulsating slack 25 of the belt 21 is reduced, so that the folded batt 3 no longer lifts off the belt 21.
  • the maximum speed of the inlet to the storage table 20 is less than the maximum speed of the discharge belt 15. Also by the acceleration and deceleration can be reduced at the inlet of the storage table 20, so that the forces acting on the transported folded Felt 3, are smaller.
  • FIG. 4 shows an example of a velocity diagram according to the invention for a movement cycle of the laying carriage, which after the FIGS. 1 and 2 is formed essentially from the laying rollers 9 and 10.

As a result, lifting of the folded fibrous web 3 from the belt 21 can be avoided.
  • the speed v 22 at the inlet of the storage table 20 is decoupled from the speed v 15 of the outlet conveyor 15, the movement of both bands must still run synchronously, the speed v 22 of the inlet of the storage table 20 is coupled to the movement and the speed profile of the laying carriage.
