Definitions

  • the invention relates to a conveyor belt with at least two revolving conveyor belts and at least two reversibly moving and accelerated at the reversal points of their route.
  • Such fleece tape layers are known in various embodiments, for example also from DE-OS 24 29 106. These serve to lay down a fiber pile in several layers to form a fleece.
  • the pile is produced in an upstream card and further processed in a machine downstream of the nonwoven belt layer, for example a needle machine. In the latter machine, the fleece is drawn together by needles and solidified, whereby a so-called needle felt is produced.
  • the fleece belt layer causes physical problems by continuously moving the pile over the conveyor belts, while the two carriages have to perform a reversing movement over a limited length and have to brake and accelerate at the reversal points. This manifests itself in material accumulations on the fleece edge.
  • DE-OS 24 29 106 one wants to counter this problem by a complicated kinematics of the carriage movements relative to one another in connection with a cyclical control of the deposit conveyor.
  • an internal buffer is formed via auxiliary trolleys, which is used to even out the depositing movement is filled and emptied. This device has not been able to prevail in practice because of the high construction costs. It also offers no solution for processing errors and influences from other machines.
  • the invention solves this problem with the features in the characterizing part of the main claim.
  • the belt speed and the speed of the car are coupled apart from the acceleration phases. With the invention, this coupling is removed and a speed difference is deliberately generated, which manifests itself in a change in the deposited pile thickness. If the laying trolley runs slower than the conveyor belt, the pile will become thicker, while, conversely, the pile thickness will decrease with a faster laying trolley.
  • the pile is elastic and can be compressed and stretched.
  • the speed difference across the route can be kept constant and at a constant height.
  • Increasing the pile thickness is advantageous, for example, to compensate for the natural shrinkage of the pile.
  • To secure the pile transport the pile is stretched a little in the nonwoven belt layer and kept under tension. The tension dissolves slowly in the discarded pile and causes it to shrink. This leads to undesirable tension in the fleece, which is counteracted by deliberate thickening of the pile.
  • a conscious increase in tension and thinning of the pile can also be used faster running car for other applications and nonwoven materials may be advantageous.
  • the speed differences can only exist in certain areas along the route and also differ in height.
  • the disadvantageous edge accumulations of the fleece can be reduced by accelerating the carriage at the reversal points beyond the normal acceleration phase to a carriage speed which is higher than the belt running speed.
  • shrinkage stresses are generated in the edge areas of the deposited pile, which reduce the material accumulation at the edge.
  • the speed difference can be reduced again after a short time in order to achieve normal pile placement.
  • Further areas of application for influencing the pile thickness according to the invention are in the rectification of existing pile defects and / or the prevention of processing defects which are produced later.
  • an upstream card can produce uneven pile thicknesses. This can be compensated for by counteracting the deposited pile thickness.
  • a downstream needle machine or similar processing device can also work unevenly over the web width. Preventive compensation can be achieved here by influencing the pile in opposite directions.
  • the speed difference according to the invention can take place by influencing the absolute speeds of the conveyor belts and / or the carriages. In view of the reversing movement of the carriages, which is necessary anyway, it is advisable to vary their travel speed and to keep the belt running speed constant.
  • the design can be different. It is easiest to provide separate drives for the wagons and the conveyor belts, one or both Drives are equipped with a freely programmable control. However, it is also possible to provide a common central drive and to change the final speeds of the carriages and conveyor belts by means of continuously or step-by-step transmissions or the like.
  • the nonwoven belt layer (1) includes a lower laying carriage (5), which deposits the pile in a reversing movement, and an upper carriage (4), which moves back and forth in the opposite direction.
  • the pile (8) is passed through two in each case on its way through the fleece band layer (1) endless conveyor belts (6,7) transported.
  • a so-called belt layer (2) is shown, in which the one conveyor belt (6) is guided in a multi-course loop over the two carriages (4, 5).
  • the second conveyor belt (7) extends into a loop of the conveyor belt (6) formed between the two carriages (4, 5).
  • the deflection rollers for the conveyor belt (6) arranged on the carriage (4, 5) are also moved during the opposite reversing movement of the carriage (4, 5), while the other deflection rollers are arranged in a stationary manner.
  • the continuously fed pile (8) passes via the carriage (4) into the transport gap between the two conveyor belts (6, 7) moving in the same direction in this area and, after passing through a loop, migrates to the laying carriage (5), from which it passes over the fleece (9) is moved back and forth and put down.
  • the deposit conveyor (11) moves the fleece (9) formed from the pile layers slowly forward.
  • the two carriages (4, 5) are connected by a common drive and move in the opposite direction at different speeds.
  • the carriage (4) runs at half the speed of the carriage (5) and thereby covers half the distance from the carriage (5).
  • the drive (12) is designed as a servo drive and is connected to a freely programmable control (13).
  • the speed of the cars (4, 5) can thus be changed as desired via their travel path, the acceleration phases in the reversal points of the travel movement being able to be influenced as desired.
  • the two conveyor belts (6, 7) have separate drives (14), preferably likewise servo drives, which, however, are acted upon by a common control (15) and are set to the same conveying speed.
  • the belt drive runs to transport the pile (8) fed in from the outside at a uniform speed (14, 15) constant, giving the conveyor belt (6) the belt running speed (V b ), which can be equal to the transport speed of the feed conveyor (10).
  • V b belt running speed
  • the carriages (4, 5) can have separate drives.
  • the carriage speed (V w ) can also be kept constant and the belt running speed (V b ) can be varied, the feed speed of the pile (8) also being varied accordingly by additional measures, such as upstream storage, etc.
  • Fig. 2 shows a so-called wagoner (3), the two wagons (4,5) each have their own endless revolving conveyor belt (6,7).
  • the carriage drives (12) can be common or separate and are connected to a freely programmable controller (13).
  • the belt drives (14) In both exemplary embodiments, a freely programmable control is provided at least for those drives which are to have a variable speed.
  • the constant drives do not need this, but can also be equipped with it.
  • servo drives in particular speed-controlled drives, are provided for the carriage drive (12), the conveyor belt drives (14) and the drive for the storage conveyor (11).
  • the servo drives have a highly dynamic motor behavior, so that the drives can be set precisely in the alcohol range to control the pile thickness in the percentage range.
  • the servo drives can be designed differently and consist, for example, of three-phase motors with frequency converters and tachometer control.
  • an online feed of the current setpoints is also provided in all movement positions of the axes.
  • the setpoints of (V w ) and (V b ) for the thickness control of the individual pile layers are thus adjusted as a function of the pile feed speed of the upstream street.
  • the relative ratio or the speed profile of (V w ) and (V b ) remains constant.
  • the speed of the deposit conveyor (11) is also adjusted so that the pile layers are deposited in an exact position and number.
  • the data records advantageously represent only the speed profile, but not the speeds actually driven.
  • the speeds can change during operation and are only calculated online via the microprocessor using the speed profiles and the current pile feed speed.
  • Fig. 3 shows in a diagram five different relative relationships between the carriage speed (V w ) and the belt running speed (V b ). 4, on the other hand, the thicknesses of the uppermost pile which has just been deposited are shown. The association of the possible variations is shown in FIGS. 3 and 4 by the same line types.
  • FIG. 3 shows the speed versus time or distance. Both diagrams assume that the tape running speed is constant. In both diagrams, the solid line represents the reference line. In FIG. 3, it illustrates the belt running speed (V b ) and, at the same time, the one possible variation in which the belt running speed (V b ) and carriage speed (V w ) are the same. For the sake of simplicity, the acceleration phases for the car speed at the reversal points are omitted in the diagrams. These can look different depending on the control type and, for example, run linearly or in a trigonometric function according to DE-OS 24 29 106.
  • the upper horizontal and dash-dotted line indicates the second variation, in which the carriage speed is greater than the belt running speed. According to the diagram in FIG. 4, this leads to a uniformly lower pile thickness.
  • the laying carriage (5) moves faster than the fleece (9) than the pile (8) is conveyed downwards by the belts (6,7).
  • the deposited pile (9) is thereby tightened and diluted accordingly.
  • the third possibility is shown in dashed lines in FIG. 3 and consists in a vehicle speed (V w ) that is lower than that over the travel path (apart from the acceleration phase) Belt speed (V b ) is.
  • V w vehicle speed
  • V b belt speed
  • the fourth variation consists of a speed difference between (V w ) and (V b ) which differs locally and temporally over the travel path.
  • the difference can be constant or, as in the exemplary embodiment shown, vary in height or location or time.
  • the carriage speed can be changed in steps or continuously depending on the type of control used and the type of thickness change desired. Opposite direction to the speed profile (V w), the web thickness is only consistently thinner than normal, then sharply reduced, then increases again and from the moment greater than normal, in which the car speed (V w) is smaller than the tape running speed (V b) is .
  • the speed curves shown in FIG. 3 can be traveled forwards and backwards on the same line. This affects the pile placement when the laying carriage (5) runs back and forth in the same way.
  • a special fifth possibility is shown in dotted lines in FIGS. 3 and 4. It relates to the compensation of the edge accumulations of the fleece (9) due to the braking and acceleration processes of the laying carriage (5) in the reversal points.
  • (V w ) is lower than the constant V b ) with the consequence of the partial pile thickening.
  • the carriage speed (V w ) is increased beyond the belt running speed (V b ) after the point of reversal, kept a piece constant and then returned to (V b ).
  • Fig. 4 shows on the left edge how the edge accumulation thereby turns into a thinning pile and then again into a normal pile thickness.
  • the deposited pile (9) in this border area has enough time to break down the border accumulation due to the artificially generated internal pile tension, which is additionally supported by natural shrinking processes.
  • the laying carriage (5) is braked to 0 at the end of its distance, which leads to the accumulation of edges shown on the right edge of FIG. 4.
  • the laying carriage (5) can also be accelerated shortly before reaching the turning point for thinning the pile and only then braked.
  • the laying carriage (5) On the way back (not shown), the laying carriage (5) in turn accelerates in the same way as on the way out beyond the belt speed (V b ). In this way, both marginal clusters are compensated for.
  • the tape running speed can therefore also change in a predetermined function over time or the distance, for example in a sine function corresponding to the DE-OS 24 29 l06.
