Definitions

  • the invention relates to a method and apparatus for adjusting the fiber orientation of carding machines.
  • the longitudinal orientation of the fibers can be counteracted by, for example, influencing the gap between the spool and the worker rolls, or by upsetting the web exiting the spool.
  • an upsetting process increases the basis weight of the web produced and thus reduces the production speed of the plant, since the length of the fiber web produced decreases.
  • a fiber orientation that is precisely matched to the final product is required today.
  • the fiber orientation can be generated throughout the fiber web, or only in selected areas.
  • the reoriented batt has much better mechanical properties for the end product in terms of strength and elongation.
  • the basis weight of the fibrous web also changes with the fiber orientation which is set in the area of the carding.
  • the adjustment of the fiber orientation on the carding is done today by manual adjustment of the relevant components, e.g. Pickups, edging rolls or random rolls, just to name a few. However, this adjustment is made manually by the machine operator, who are subject to subjective observation and thus are very time and material intensive due to the required iteration steps with interim laboratory analysis.
  • the fiber orientation of the batt is determined and generates a first controlled variable, wherein subsequently in the transport direction of the batt Basis weight of the batt determined and generated as a second controlled variable, wherein the first and second controlled variables are compared with the associated reference variables, and that in case of deviations of the controlled variables of the reference variables by means of a signal at least one actuator for changing the fiber orientation and / or at least one actuator is operable to change the basis weight.
  • the fiber orientation is measured in the transport direction of the batt behind the transfer rollers on at least one outlet side. Before this point of measurement thus takes place the setting for the fiber orientation on the compression rollers, the pickup rollers, the random rollers, or on the spool. Since the basis weight of the batt changes as a result of the adjustment of the fiber orientation, the basis weight is measured in the transport direction of the batt after the first measuring element for fiber orientation.
  • the actuation of the actuators takes place stepwise at predetermined time intervals, so that no overregulation takes place, in which the fiber orientation and the production quantity or production rate are subject to large fluctuations.
  • the time interval is formed from a measuring time of the measuring elements and a dead time, so that the controlled variables can approach the reference variables.
  • the dead time results from the distance of the adjusting members to be adjusted and a measuring element. This is only readjusted when the effects of the changed actuators can be detected by the measuring elements.
  • the controller comprises a map controller, which can map the complex interactions by means of fuzzy logic and can respond to the possible disturbances by means of empirical values for different types of fibers.
  • the controller is an integral part of the control of the carding machine.
  • the first measuring element comprises at least one CCD camera which is suitable for determining the orientation of the fibers over substantially the entire width of the fiber web. It can be a single CCD camera, which monitors the entire working width with a large perspective away from the batt, or it can be a single CCD camera that periodically moves the working width a short distance from the batt. Furthermore, several CCD cameras can be arranged over the working width of the batt, whose measuring ranges can partially overlap. The CCD cameras enable the determination of the MD / CD ratio practically in real time, so that a very fast control of the production process without loss of production is possible. As an alternative to the CCD cameras, high-resolution video cameras or alternative optical measuring elements with image analysis program can also be used.
  • the second measuring element may be formed as a radiometric or optical measuring device or as a belt scale, with a reliable and accurate measurement of the basis weight is possible.
  • the actuators are designed as highly dynamic servomotors or linear drives that can react very quickly to changes in the actuators.
  • the rotational speed or peripheral speed of the doffer rollers and / or the compression rollers and / or the idler rollers can be adjusted. It has proven to be advantageous if the setting of the fiber orientation, the compression of the batt occurs in several stages. That is, a subsequent roller, for example, the first upsetting roller behind the pickup roller has a lower speed than the pickup roller. In addition, then the subsequent compression roller again has a lower speed than the first compression roller. This allows the fiber orientation to be set very precisely to a predetermined MD / CD value.
  • the distances between the pickup rollers and / or the compression rollers and / or the random rollers can be adjusted to one another by means of the servomotors or the linear drives. Even so, the batt can be compressed and thus the fiber orientation can be adjusted.
  • the combination of changing the peripheral speed and changing the distances of the rollers to each other is possible and useful.
  • the size of the carding gap on the spool can be adjusted by means of at least one servomotor or linear drive.
  • the fiber orientation is set very early in the batt, which can have a positive effect on the control time.
  • the amount of fiber flakes or the layer thickness of the fiber flakes on the conveyor belt in front of the carding machine can be influenced via an actuator basis weight. This can be a consistent production length or Production quantity can be ensured at Fibrous, so that the subsequent production plants can drive continuously.
  • a further advantageous embodiment of the method provides that in a carding machine with two deduction aggregates, the fiber orientation and the basis weight in the range of each conveyor belt is measured before the batt is brought together and solidified, since after merging the batt accurate measurement of the fiber orientation and thus the regulation is made more difficult. Furthermore, this process step offers the possibility of producing two battings with different fiber orientation and subsequently solidifying them, so that a consolidated batt can be produced which can be optimally adapted to desired product properties.
  • a further improvement of the invention can take place in that the measuring elements are arranged in the region of the conveyor belt, in which the two batts are joined together.
  • the measuring elements for the lower batt are arranged below the lower conveyor belt, while the measuring elements for the upper batt are arranged above the upper conveyor belt.
  • the inventive apparatus for adjusting the fiber orientation of carding machines comprises a first measuring element which is suitable for determining the fiber orientation of a batt. Furthermore, it comprises a second measuring element which is suitable for determining the weight per unit area of the fibrous web, and a controller which compares the control variables for fiber orientation and the basis weight from the measuring elements with the respective reference variables. In the case of deviations of the controlled variables from the reference variables, the controller generates a signal, by the at least one actuator for fiber orientation and / or at least one actuator for basis weight can be actuated.
  • the first measuring device in the transport direction of the batt is arranged behind transfer rollers on at least one outlet side.
  • the second measuring device is arranged in the transport direction of the batt after the first measuring element, so that with the adjustment of the fiber orientation, with which the basis weight can change, the basis weight measured and can be influenced before the carding machine. Subsequent continuous production is thus guaranteed.
  • the first measuring element with the at least one CCD camera determines the fiber orientation practically in real time, an online detection of process deviations is possible, whereby a continuous measurability and a regulation based on the fleece quality is ensured. Errors caused by technical problems in the card, such as garnish wear, dirt or clogging or incorrect machine settings, can be immediately detected and eliminated. Online monitoring of production makes it possible to reduce process costs.
  • FIG. 1 a known carding machine 1 is shown, which has an inlet side 1a for fiber flakes and one or more outlet sides 1b for fibrous web 20.
  • an unillustrated feeder is arranged, for example, a Ganttelschachtspeiser with which the fiber flakes are deposited on a conveyor belt, not shown.
  • the conveyor belt is equipped for example with a radiometric or optical measuring device or a belt scale, which measures the fiber layer deposited on the conveyor belt and feeds the data to a controller.
  • the weight data are compared with the processing speed of the carding machine 1, so that the carding machine produces a uniform batt 20 at approximately constant speed.
  • the carding machine 1 can also be equipped with a card feeder with integrated non-woven thickness measurement, in which the weight is determined by the web thickness measurement.
  • the fiber flakes are fed to the inlet side 1a of the system and passed through feed rollers 2, 3 and pre-drum transfer unit 4 to the drum 5, so that the fiber flakes are dissolved and aligned to the single fiber.
  • the fibers on the pre-drum 3 and on the spool 5 so that a fibrous web 20 forms after the spool fifth is transported from the doffer roller 8 in the direction of outlet side 1 b.
  • the spool 5 rotates clockwise and passes the generated batt 20 to an upper and a lower counter-rotating doffer roller 8.
  • the batt 20 can be transferred from the spool 5 to the doffer rollers 8, is between spool 5 and doffer rollers 8 set a very small gap. Furthermore, the surface of the doffer rollers 8 is designed so that between the roller surface and the fibers to be transferred a positive connection can occur.
  • the take-up rollers 8 are followed by one or more compression rollers 9, 9 ', and a take-off unit in the form of a circulating conveyor belt 11, which may optionally be equipped with one or more transfer rollers 12.
  • carding machine 1 is equipped with a lower and an upper take-off unit and can thus produce two separate layers Faserflor 20. It is of course also possible to equip the carding machine 1 with only one deduction unit.
  • FIG. 2 is a plan view of an expiring from the carding 1 sliver 20, wherein the region of the carding 1 is indicated without further details.
  • a first measuring element 13 which measures the fiber orientation of the batt 20.
  • the first measuring element 13 may comprise one or more CCD cameras which measure the orientation of the fibers across the width of the fibrous web 20.
  • the measurement result is the MD / CD ratio of the fiber orientation, which as the actual value or controlled variable 13a is assigned to a controller 15 (FIG. FIG. 2 ) is supplied and compared with a setpoint or a reference variable 16 for the fiber orientation.
  • the CCD cameras determine the fiber orientation almost in real time, in which an LED lamp illuminates the fiber pile with light and the resulting resulting images converted by a special algorithm in the fiber orientation.
  • Alternative solutions to CCD cameras are of course possible, in which optically, for example by means of high-resolution video camera and associated image analysis program, the fiber orientation can be determined.
  • a second measuring element 14 Downstream of the first measuring element 13 in the direction of the outlet side 1b, a second measuring element 14 is arranged, which measures the surface weight of the fibrous web 20.
  • This second measuring element 14 can be embodied as a radiometric or optical measuring device or as a belt scale, which supplies the actual basis weight to the controller 15 as a second actual value or controlled variable 14a.
  • the predetermined basis weight is supplied to the controller 15 and compared with the second controlled variable 14a for the basis weight.
  • the controller determines 15 different predetermined manipulated variables acting on various actuators 18, 19, 19 ', 19 ", 19' '', ..., which in turn affect the fiber orientation and / or the basis weight.
  • Actuators for the fiber orientation 19, 19 ', 19 ", 19''', .. can be highly dynamic servo drives or linear drives of the pickup roller 8, the compression rollers 9, 9 ', and / or the random rollers 10 ( FIG. 3 ), with which the distances of these rollers 8, 9, 9 ', 10 to each other and their differential speeds are regulated.
  • serve as actuator 19 is a servo drive or a linear drive, with which the size of the carding nip is set on the drum 5.
  • the batt 20 is compressed and thereby reoriented the fibers in the transverse direction.
  • the upsetting of the batt 20, however, has the consequence that subsequently the desired Surface weight of the batt 20 increases, whereby the batt 20 is denser and thus a shorter production length is generated. As a result, the production speed of the following system also decreases.
  • the amount of fiber flocks fed in can be reduced by means of the actuator basis weight 18 in front of the carding machine 1, whereby a thinner layer of fiber flakes is conveyed to the conveyor belt, which however is conducted faster to the carding machine 1, so that the controlled variable Basis weight 14a again the reference variable basis weight 17 approximates.
  • the same effect is achieved in that the gap between the doffer roller 8 and the compression roller 9 is reduced. This also leads to an increased reorientation of the fibers in the transverse direction, which increases the basis weight of the batt 20 and thus reduces the production length. In both cases, the MD / CD ratio becomes larger.
  • a multi-stage compression of the batt 20 has the advantage that the MD / CD ratio can be set very accurately, wherein the greatest influence on the fiber orientation by the differential speed between the doffer roller 8 and the first compression roller 9 is formed. The differential speed between the first and second upsetting rolls 9, 9 'refines the desired result.
  • the actuators servomotors 19, 19 'and 19 can control the peripheral speeds of the take-off roller 8 at 290 m / min, the first upsetting roller 9 at 170 m / min and the second upsetting roller 9' at 140 m / min, whereby a total of 2, so that a fiber orientation results with an MD / CD value of 1.1
  • the actuator basis weight 18 is increased, so that the controlled variable basis weight 14a of the reference variable basis weight 17 again adapts ,
  • the servo motors 19, 19 'and 19 can control the circumferential speeds of the take-off roller 8 at 280 m / min, the first upsetting roller 9 at 210 m / min and the second compression roller 9 via the actuators 19, 19' and 19" At 180 m / min, this results in an overall compression ratio of approximately 1.6, resulting in a fiber orientation with an MD / CD value of 3.1.
  • the actuator becomes area weight 18 increases, so that the controlled variable basis weight 14a the reference variable basis weight 17 again adapts.
  • the arrangement each having a first measuring element 13 behind the upsetting rollers 9, 9 'in the region of the conveyor belts 11, has the advantage that the fiber web 20 is not yet solidified and is dissolved up to the individual fiber. If the two fibrous webs 20 are combined and only then the fiber orientation is measured, problems can result due to different pile structures, which make the overall control concept significantly more complex. This has a particularly serious effect when due to the Randabsaugung in the carding machine extracted pre-opened fibers are recycled in the process, whereby the fiber orientation is no longer uniform and / or mass fluctuations over the bandwidth can occur.
  • the controller 15 is advantageously an integrated map controller, which can map the complex interactions by means of fuzzy logic.
  • This controller 15 is also an integral part of the control of the carding machine 1, which can thus compensate for the resulting disturbances in the process such as mass fluctuations or different fiber components.
  • the controller 15 always adjusts the actuators 19, 19 ', 19 ", 19"' only stepwise, the adjustment taking place at calculated time intervals, which is formed from the measuring time and the dead time. For example, a time of one second can be defined as the measurement time.
  • the dead time is calculated from the distance of the adjusting members to be adjusted, for example, to the first or second measuring element 13, 14, so for example the distance between the servomotors of the doffer roller 8, or the compression rollers 9, 9 'to the first measuring element 13 with reference to the production speed of the batt 20.
  • the value of the adjustment for the actuators 18, 19, 19 ', 19 ", 19' '' is an empirical value that may be different for different types of fibers and has been input to the controller 15.
  • the controller's map is empirical Values which are based on the material of the batt, the MD / CD ratio, the thickness and thus the basis weight of the batt These values are stored in the characteristic field of the controller 15 and thus control the deviation of the control variables (13a, 14a) from the reference variables (16, 17) the magnitude of the change in the rotational speeds or the nips, in particular in the change of the nips, in which d If the weight per unit area is changed directly, a signal can be sent directly to the actuator weight per unit area (18), which influences the feed rate or the amount of fiber flakes fed in front of the carding machine.
  • FIG. 3 differs from FIG. 1 only by the arrangement of the random rollers 10 between the spool 5 and Due to their peripheral speed, direction of rotation and tooth position, the random rollers 10 generate a special random position in the batt 20, which is compressed and reoriented by the following doffer and upsetting rollers 8, 9, 9 '.
