Definitions

  • the invention relates to a winding machine for winding slivers of cotton wool, with a winding unit, on or in which a winding is formed, wherein the winding machine has a device for generating a winding force on the lap roll.
  • the invention relates to a method for winding slivers.
  • the today usual feeding of flat combing machines is done by cotton wool, which were previously produced in winding machines from individual bands.
  • the winding machine receives the template in ribbon form of at least one route, the template is cached in round or rectangular cans.
  • the winding machine usually consists of a winding unit with at least two winding rollers on which the lap roll is formed by means of a sleeve. Preceding the winding unit are usually at least a pair of pressure rollers which deflect the bands, compress and / or possibly stretch. Before the pressure rollers, an inlet region is arranged by a further compression unit or a smoother can be arranged.
  • the quality of the produced roll is decisive for the productivity of the subsequent combing machine, as well as the producible quality of the sliver and the required amount of noil.
  • a high uniformity, low hairiness and a good rolling characteristics characterize a good winding, so that the comber runs with the least possible standstill.
  • the EP 0945080 A2 describes a winding machine in which the lap roll is produced by a circulating belt.
  • the winding machine has a plurality of sensors and measuring devices with which indirectly the winding diameter is determined in order to reduce the winding pressure with increasing winding diameter.
  • the DE 102006020586 A1 describes a method for winding cotton wool, in which by means of a speed control device for driving the winding rollers, the respective wound lap length is determined, and is assigned to a decreasing winding pressure. As the winding diameter increases, the winding pressure gradually decreases.
  • the EP 0140168 A2 describes a winding machine with a varying winding pressure, which builds on the increasing winding diameter a constant contact pressure.
  • the CH 283013 is based on the recognition that with increasing thickness of the coil, the contact pressure decreases. By continuously increasing the load on the winding tube and winding roller, the decreasing winding pressure is automatically compensated.
  • the winding machine for winding fiber slivers of wadding comprises a winding unit, on or in which a winding is formed, wherein the winding machine has a device for generating a winding force on the lap roll.
  • the invention is characterized in that the winding machine has at least one sensor for determining the actual diameter of the lap roll during the winding process, and that the winding force can be varied depending on the resulting bubbles.
  • the winding force does not decrease with increasing winding length, but at least at the beginning of the winding process continuously.
  • the surface pressure between the lap roll and the winding rollers is not reduced as much as in a sloping curve due to the increasing contact surface of the growing coil.
  • An increased occurrence of the Walkens on the winding rollers can be counteracted by the steepness of the curves.
  • the inner layers are strengthened so far that only a slight walking occurs.
  • Another difference is the continuous increase of the winding force to a maximum value.
  • the winding force over the winding length by means of a control is adjustable.
  • the winding machine in addition to the controller on a database in which are stored for different fiber materials, the optimal data for the winding curve for each fiber mixture.
  • the winding curve can also be generated via arbitrarily settable setting points on the control of the winding machine. It can e.g. At the beginning of the winding, where a strong change in the winding force makes sense, the set points are set at short intervals. At the end of the winding formation, in which a constant high winding force can be useful, the distances between the setpoints can be increased. Due to this flexible definition of the set points over the winding length, the winding curves can be freely modeled, whereby the winding machine can adapt to the process, the production conditions and the fibers presented arbitrarily.
  • a continuous increase in the winding force is considered as at least direct, ie straight or curved connection between two setpoints. This distinguishes the invention from the prior art, in which the setting points are approached in stages, with the disadvantage that a steep increase in the winding force is possible only in large jumps.
  • an efficient control can interpolate a continuous curve through all setting points, so that the winding curve no longer has any break points, which has a very positive effect on the hairiness and the rolling behavior of the roll in the combing machine.
  • the inventive method for winding fiber slivers is characterized in that the winding force over the winding length along a varying winding curve is adjustable, whereby the winding force increases continuously at least at the beginning of the winding process, and that the winding force is variable depending on the resulting bubbles during winding.
  • both the steepness of the winding curve, as well as the position or the Course of the winding curve for example, up to 20 kN winding force can be varied. Since bubble formation can increase with increasing winding speed, this effect can be counteracted by a steeper rise and an increase in the winding pressure.
  • the actual diameter of the lap roll is determined by a sensor.
  • the controller determines whether large or locally smaller bubbles have been created by entrained air.
  • the control regulates the winding force until the deviation of the diameter is within a tolerance field, which may be, for example, 1 mm difference in diameter.
  • the desired diameter of the lap roll can be determined by a sensor that transmits the number of revolutions of the lap roll to the controller. Due to the preset fiber quality and the thickness of the wadding or sliver, the controller determines the nominal diameter of the wadding at all times. Depending on the fibers to be processed, the controller also processes correction values for the lap behavior of the lap roll, the deformation of the lap during winding and other material-dependent parameters.
  • slivers are generally cotton, for example made of cotton, fibers, fleece or pile, which can be wound up in a spinning mill for intermediate storage, transport or further processing.
  • the slivers or conveyor belts are doubled in the area of the table calenders or drafting systems in the inlet area to a cotton wool band.
  • FIG. 1 a winding machine 1 is shown, as used for example in the Kämmismevorrung in the textile industry.
  • Several slivers 3, which may consist of natural or synthetic fibers are fed via cans of the winding machine 1 and stretched in a drafting system, not shown.
  • the slivers 3 are further passed over an inlet region 2 to a plurality of pressure rollers 4a - 4c, which guide the slivers 3 in the catchment area between two winding rollers 5a, 5b and a winding tube 6 for producing a lap roll.
  • a supercharger 8 may be arranged, which makes the sliver 3 uniform.
  • the lap roll can also be produced within an endlessly circulating belt or between one or two winding rollers and a circulating belt.
  • a sensor L1 may be arranged, which determines the diameter of the lap roll 15 during the winding process.
  • the sensor N1 can determine the number of revolutions of the lap roll 15.
  • a cotton roll 15 has already been placed on a transport device 20.
  • the sliver 3 between the pressure rollers 4b and 4c was demolished by the Winding rollers 5a and 5b continue to rotate and, for example, the pressure rollers 4b and 4c are stopped very quickly.
  • a tearing of the sliver 3 is also possible between the pressure rollers 4c and the winding roller 5a.
  • one of two slides 10 can be seen here, which are obliquely movable along a guide 12 arranged on both sides of the machine housing. The carriage or carriages 10 are moved along the guide 12 by means of at least one cylinder 13, for example a pneumatic cylinder.
  • Each carriage 10 has its own reel disc 9, which are movable toward or away from each other and thereby can hold the winding tube 6 by clamping.
  • a new winding tube 6 is placed laterally through the opening 11 in the gusset between the winding rollers 5a, 5b.
  • the winding tube 6 can be placed through another machine opening in the gusset between the winding rollers 5a, 5b.
  • the reel disc 9 move with the carriage 10 obliquely down in working position and clamp the winding tube 6 a.
  • New sliver 3 is introduced via the pressure rollers 4a, 4b, 4c in the gusset between the winding rollers 5a, 5b and the winding tube 6, so that - after the winding tube 6 was clamped by the winding plates 9, the winding process by rotating the winding rollers 5a, 5b can start, which represents the beginning of the winding position, which moves with increasing outer diameter of the lap roll 15 to be formed against the pulling direction Z.
  • the cylinder 13 pulls the carriage 10 along the guide 12 in the pulling direction Z, so as to build up a static winding pressure or a dynamic winding pressure corresponding to the winding quality to be achieved.
  • the lap roll 15, the winding tube 6 is clamped by the reel disc 9, pulled against the winding rollers 5a, 5b.
  • the lap roll can also be formed solely by a band or a band with a roller.
  • the fiber ribbons 3 in the region of the pressure rollers 4a, 4b, 4c or the winding roller 5a are torn off and the finished lap roll 15 is transferred to a transport device 20.
  • FIG. 3 the winding pressure or the winding force over the winding length is shown.
  • the winding length of the lap roll in meters is plotted and on the ordinate the winding force in kilo-Newton.
  • the winding force is converted into a winding pressure in a control.
  • a winding force of 12 kN can be assigned a winding pressure of 6 bar, which is applied via two pneumatic cylinders.
  • the winding machine can apply a pressure of 16 kN, which corresponds to a system or winding pressure of twice 8 bar.
  • a winding force of 20 kN can be applied, which corresponds to a system or winding pressure of 10 bar for two cylinders 13 of the same size.
  • the winding force does not decrease with increasing winding length, but continuously. Another difference is the continuous increase of the winding force to a maximum value.
  • the increase or decrease of the winding force in stages is known, which has a negative effect on the hairiness of the unwinding reel, since with each new stage of the lap roll in the rolling suddenly or abruptly change, which is negative in the comber makes noticeable.
  • the winding pressure increases from a low value in the winding interior (for example, at a winding length of 0 to 50 m) a maximum value.
  • the surface pressure between the lap roll 15 and the winding rollers 5a, 5b does not decrease as much as in a sloping curve due to the increasing contact surface of the growing coil.
  • An increased occurrence of the Walkens on the winding rollers 5a, 5b can be counteracted by the steepness of the curves.
  • the inner layers are strengthened so far that only a slight walking occurs.
  • the upper curve in FIG. 3 shows the course of the winding force, as it can be set by default in normal cotton, such as Matto Grosso.
  • the winding force begins at Anwickeln, so with a winding length of 0 m with about 3.6 kN and increases up to the winding length of about 50 m to the maximum value of 12 kN.
  • the lap roll is applied to the final length of 400 m, that is, over the remaining winding length of about 350 m with a continuously constant winding force is wound.
  • reference points ⁇ are given in this example, which can be stored in the machine control, whereby the winding force increases continuously from one to the next reference point, and not abruptly, as in the prior art.
  • the lower winding curve has 10 reference points ⁇ , which are stored in the control of the winding machine, whereby the winding force increases continuously from one to the next reference point.
  • the winding pressure starts at 0 m winding length with about 3.6 kN and increases continuously up to a winding length of 300 m to 12 kN.
  • the remaining 100 m winding length up to a winding length of 400 m is again wound with a constant winding force of 12 kN.
  • Fibers can be varied both the steepness of the winding curve, as well as the position and the course of the winding curve, for example, up to 20 kN winding force. Since bubble formation can increase with increasing winding speed, this effect can be counteracted by a steeper rise and an increase in the winding pressure.
  • the definition of the winding curve can be stored as a preset function of the fiber quality in the control of the winding machine.
  • the winding curve can also be generated via arbitrarily definable setting points ⁇ , ⁇ on the control of the winding machine. For example, at the beginning of winding, where a large change in the winding force makes sense, the setting points can be set at short intervals. At the end of the winding formation, in which a constant high winding force can be useful, the distances between the setpoints can be increased. Due to this flexible definition of the set points over the winding length, the pressure curves can be freely modeled, whereby the winding machine can adapt to the process, the production conditions and the fibers presented arbitrarily.
  • the adjustment of the pressure curve takes little effort on the display of the machine control of the winding machine.
  • the specified setpoints are connected linearly, so that no jumps occur in the course of the curve.
  • the controller interpolates the increase in the winding force over the set winding length to the next setting point.
  • the winding curve has only slight creases in the curve, which, depending on the control, can also be interpolated into a single continuous curve and thus has neither cracks nor kinks.
  • the blistering can be reduced, whereby the winding speed and the quality of the lap roll is increased.
  • the subsequent combing process is also positively influenced as the amount of combing is reduced and thus the change of the lap roll is reduced.
  • a laser sensor L1 within the winding machine 1 with which the actual diameter of the lap roll 15 can be measured during the winding process.
  • a plurality of sensors L1 can be arranged across the width, or a sensor L1 can be moved over the width of the lap roll 15.
  • the sensor L1 can also be designed so that it can detect the almost complete width of the lap roll 15.
  • the one or more sensors L1 may be arranged stationarily on the housing of the winding machine, or be arranged on the carriage 10 or together with this movable.
  • the quality of the fibers to be processed is entered, so that the thickness of the cotton or sliver 3 is determined by the setting of the upstream drafting and table calenders in the inlet region 2.
  • the sensor N1 which may be formed as an inductive proximity switch, the number of revolutions of the lap roll 15 can be determined.
  • the current target diameter is determined as a reference variable of the lap 15 from the number of layers and the thickness of the cotton or sliver 3 and compared in the control with the actual diameter. If the actual diameter as a control deviation in the millimeter range is greater than the nominal diameter, a bubble may have formed during winding, for example.
  • the controller then varies the pressure in the cylinders 13, whereby the winding force can fall or rise.
  • the actuators of the winding rollers 5a, 5b can be controlled as actuators, so that the winding speed is reduced until the nominal diameter with the actual diameter of the lap roll 15 is again in a predetermined tolerance field.
  • the resulting bubbles during winding can occur locally due to entrained air, whereby one or more separate bubbles between the outer layer of the sliver or sliver 3 and the lap 15 arise. If it is then continued with the same winding force and, if necessary, at the same speed, it can form a large-area blister which divides the formed cotton or sliver 3 into irregular strips, since the air wishes to escape, as a result of which there are gaps due to stresses in the collected air.
  • the diameter of the lap roll 15 can increase locally by several millimeters.
  • the entrained air can lift the cotton or sliver 3 up to 10 mm from the wadding 15, which can be clearly determined by means of the laser sensor (s) L1.
  • the control of Winding machine is provided with a tolerance field, .so that deviations, for example, in the range up to 1 millimeter do not affect the winding force and the winding speed, since small air bubbles can dissolve again.
