Definitions

  • ABSTRACT OF THE DISCLOSURE A tension adjustment for stretching and winding machines which produce spools or windings of thread or other textile fibers.
  • the thread or other material before taken up by a motor driven rotary winding body is guided over at least one motor driven tension controlling rotary body.
  • the two motors are controlled in their relative speeds to, one another in such a manner that the rotary body controls and changes the tension in the material to be wound up, while the other motor in accordance with the gradually increasing diameter of the winding forming on the winding body is so controlled that it drives the winding body with a gradually decreasing speed.
  • the invention relates to a tension adjustment arrangement for stretching and winding machines, and particularly is directed to stretching and winding machines used in the textile and fibrous material industry, in which the material to be wound, as for example, threads, bands, foils or the like, are conducted over motor-driven rotary bodies, for example, reels, rollers or the like, and con ducted to motor-driven winding bodies, as for example, rollers, sleeves, spools or the like.
  • the spools are driven by means of friction applied to them by driving rollers rotating with constantly adjustable rate of revolutions.
  • This friction drive of the spools is, however, no longer to be recommended at winding velocities of over 2000 meters per minute and with spool weights of over approximately 10 kg., as the required transmission torques between the surface of the driving roller and surface of the spool increase in such manner that the spool surface owing to the required bearing pressure is sympathetically affected, so that individual capillaries of the threads may be damaged.
  • the windings of the threads form at the commencement of the winding are very flat ellipsoids, while at the end of the winding operation, when the winding has a two to three-fold diameter compared with the winding sleeve, there will be produced very round ellipsoids.
  • the flat and round elliptical shape of the thread windings different tensional stresses result between the start and end of the winding operation. Accordingly in view of the frictional engagement already mentioned between roller and winding material, it is not possible to carry out a regulation of the tensile stress under the mentioned changeable conditions.
  • the winding devices ordinarily used regulate the tensile stress to a constant, adjustable value during the winding operation, and this is done by means of a jig arm or feeler lever control.
  • the winding material is guided over a jig roller fixed on a feeler or indicator and forms a loop movable up and down and subjected to tension.
  • the feelers and jig rollers must be balanced and low in weight.
  • the jig rollers are subjected to high rates of revolution in the arrangement, which results in additional friction moments. This has the disadvantage, that in view of the inclination to oscillation of the feeler and the high rates of revolution of the jig rollers, these winding devices are liable to disturbance when winding speeds of over 1000 meters per minute are employed.
  • the thread can be placed over the jig or compensating roller. The higher the speed of the thread supplied, the more difficult is the placement and the commencement of the winding operation.
  • this problem is solved in this way, that for the attainment of an optimum stretching of the winding material and an optimum winding body, the tension regulation is made automatically adjustable on the basis of two factors which are independent of one another, and which is adjustable in accordance with the stretching relation and the winding material to be taken up in a constant drawing, or in a drawing in dependence on the stretching range and changeable from the resulting diameter of the winding in such a manner that a stretching motor of a rotary stretch body and/ or a winding drive motor of a winding body is statically and astatically controlled each by a tension adjustment means of a synchronously rotating motor.
  • the tensile stress can be varied in relation to the particular winding diameter, in order to produce stable and easily unwindable windings.
  • the tensile stress dependent on the particular winding diameter which leads to an inner and outer compacting of the winding is not known in the winding machines previously used, it has frequently occurred that particularly windings consisting of synthetic threads have been pressed apart in the lower range of the thread layers, because when the winding is formed, the contraction of the thread takes place most strongly in the outer range of thread layers.
  • easily distorted or dislocations of the thread layers occurred, which upon unwinding caused the thread to break and thereby the winding became useless for further treatment.
  • the adjustable tension regulation takes place by a rotary body which is constructed as rotary regulating body, whereby for the stretching of the winding material, the basic speed guide value as well as the guide value dependent on the tensile stress are effective, while for the wind-up of the winding material the basic speed guide value as well as the guide value dependent on the diameter are effective.
  • the rotary regulating body is associated with a tension adjusting means which consists of a weight-loaded torque dynamometer and an adjusting member, and which is disposed on the rotatably mounted stator of a synchronously rotating motor, whose rotor is connected with the rotary regulating body.
  • the torque dynamometer is hereby provided with interchangeable rope pulleys, one having a circular shape and others different circumferential cam shapes, while the rope passing over the selected pulley is provided with weights at its ends.
  • the winding drive motor for the winding body by means of an adjusting member is in connection with the tension adjusting means, whose statically controlling adjusting member, on the one hand, controls the regulation of the number of revolutions of the winding drive motor with constant winding material speed, while its predominantly astatically controlling torque dynamometer, on the other hand, additionally influences the adjustment of the adjusting member, so that the tensile stress of the winding material in the progress of the winding is functional related to the particular winding diameter.
  • the invention is further characterized in this, that the two guide values produced by a synchronous generator independently of one another are in their value proportional to the speed of the winding goods, whereby the first, the basic speed guide value is so determined that the latter through a setting member gives to the winding drive motor of the winding body the speed corresponding to the winding material when the winding body is empty, and the second, the diameter dependent guide value, which is directed opposite to the first basic speed guide value, is supplied to an adjusting member, for example, a potentiometer, whereby upon commencement of the winding, its one stop position corresponds to the maximum number of revolutions of the winding drive motor when the winding body is empty and a zero position of the guide value dependent on the diameter, while upon ending of the winding, its other stop position corresponds to the minimal number of revolutions of the winding drive motor when the winding body if filled and maximum position of the guide value dependent on the diameter of the winding.
  • the two guide values produced by a synchronous generator independently of one another are in their value proportional
  • a switch is disposed in the two-stop positions of the adjusting member for the indication of disturbance of the regulating drive.
  • the disturbance indicator is operated when the desired winding speed and the adjusted tensile stress of the winding material are not fulfilled during the winding operation.
  • reaction adjusting motor The winding material supplied to the winder is guided positively over the rotary regulating body which is driven by a synchronously rotating motor, which latter in the following is designated as reaction adjusting motor.
  • This reaction adjusting motor is energized by a synchronous generator with adjustable frequency, so that the circumferential speed of the rotary control body corresponds to the corresponding supply speed of the winding material.
  • the adjustment of the frequency takes place either by means of rotating converters and regulating drives or over a static frequency changer.
  • reaction adjusting motor a motor of ordinary construction may be utilized or a motor of the external rotor type.
  • the regulating rotor is fixed to the shaft of the rotor, while the stator is not mounted rigidly as customary, but is rotatably mounted in easily manipulatable bearings.
  • the required torque produced by the shaft of the rotor, namely by the rotor body produces on the rotatably supported stator an equal reaction force, so that the stator rotates in the opposite direction as the rotor. If no torque is required by the reaction adjusting motor, then, if the frictional bearing losses are neglected no reaction moment is produced, so that the stator stands still. If, however, the rotary regulating body is driven in direction of rotation more rapidly than the synchronously rotating reaction adjusting motor, then the stator rotates likewise owing to the reaction force in the direction of rotation of the rotor.
  • the rotatably supported stator does not move, when the tensile force in the arriving winding material is equal to the tensile force in the winding material running off the winding drive, that is, when the tensile force of the driving motor of the winding body is equally great.
  • the winding material carried off attempts additionally to accelerate the rotary control body in its direction of rotation, whereby the stator of the reaction adjusting motor is rotated in direction of rotation of the rotary control body. If the opposite tension relations prevail, however, in which the tensile force in the winding material disposed between rotary control body and the winding drive is smaller than the tensile force in the winding material supplied to the rotary control body, then the rotary control body is braked and the stator rotates opposite to its direction of the control body.
  • This direction of rotation of the stator is made use of for the control of the rate of revolutions of the winding drive motor of the winding body. If the tensile force in the winding material between rotary control body and the winding drive is excessive, then the rotation of the stator in the direction of rotation of the rotary control body causes a change in a measuring value dependent on the rotation of the stator so that the speed of the winding drive motor is reduced.
  • the stator of the reaction adjusting motor is rotated oppositely to the direction of rotation of the rotary control body, so that in this manner the variable measuring value is so adjusted that the number of revolutions of the winding drive motor is increased.
  • the measuring value which is variable by the rotation of the stator is so altered that normally a single revolution of the stator is sufiicient to attain the entire required difference in the range of revolutions between an empty winding body and a fully wound winding body.
  • the stretching force with the desired end stretching is constant when the cross-section of the supplied material is constant or when the amount of material per unit of time is constant.
  • the described tension control for winding drives is a preponderately astatic tension control device
  • this arrangement may also be utilized for the stretching of winding material which subsequently is wound up directly with the same tension control used for winding drives.
  • the invention provides that for the stretching of the winding material, at least one rotary control body and one rotary stretching body are provided, whereby the rotary control body is driven by a synchronously rotating motor in connection with the tension-setting device, and the rotary stretching body is driven by a stretch motor with regulated rate of revolutions.
  • the stretched winding material as for example, threads
  • a further great advantage of his arrangement consists therein that several such spinning stretch winding points, even though they have the same material feed speed from the spinning nozzles may be completely independently of one another in the stretching step. This is insofar important, because previously upon presumption of the transfer ratio for the stretching upon thread breakage at a s inning point, the material which would be conveyed to this spinning point, caused a loss of material, until the winding of the other spinning points had the required end dimensions, as for the new start of the spinning operation of the machine, a transfer ratio of 1:1 is necessary to provide for no stretching.
  • the previously employed diameter dependent guide value In order to introduce the tension control of the winder for the stretching of the threads, the previously employed diameter dependent guide value must not be arranged opposite to the basic conveying speed, but must be arranged in the same direction to the basic speed conveying value. as the subsequent rotary stretch bodies upon stretching must have a higher rate of revolutions. The resultant total conveying value must accordingly be greater.
  • the diameter dependent conveyance value is designated during the stretching operation as tensile stress dependent value.
  • the tension dependent guide value extends in the same direction as the basic speed conveyance value, whereby upon using an additional weight on the torque dynamometer of the rotary control body, the sum of both conveyance values increases in such manner that the rate of revolutions of the stretch motor of the rotary stretch body becomes so high that the winding material is optimally stretched between the rotary regulating body and the rotary stretch body.
  • the additional Weight which is added during the time period of the introduction of the stretching process to the weight on the torque dynamometer of the rotary control body corresponds to the stretching force of the winding material.
  • the stretch motor of the rotary stretch body drives a synchronous generator, which energizes a following rotary control body, which regulates the winding of the stretched winding material on the winding body.
  • FIG. 1 illustrates a sectional view of a synchronously rotating motor with a rotary control body and of a motor driving a wind-up-body;
  • FIG. 2 illustrates a circuit diagram for the automatically adjustable tension regulation
  • FIG. 3 illustrates an arrangement of a tension egulation for spin-stretch winding.
  • a synchronous generator is regulated by the motor 1 through a coupling 2, a positively connected variable speed transmission 3 and another coupling 4 to the desired rate of revolutions, said synchronous generator furnishing a speed-proportional and frequency-proportional torsional stress.
  • This synchronous generator 5 energizes by means of slip rings 6 the stator 7 of a synchronously rotating motor 8, which in the following is designated with reaction adjusting motor, so that the rotor 9 sets in rotation a rotary control body 10, for example, a regulating tension roller, with a circumferential speed which is determined by the diameter and the frequency.
  • the synchonous generator 5 feeds the primary winding 11 of a three-phase transformer, Whose one winding 12 furnishes with a rectifier 13 the basic speed guide value 14 directly to an electronic setting member 15, While another winding 16 with a rectifier 17 over a rotatable adjusting member 18 produces the diameter dependent guide value 19 during the winding operation or the tension dependent guide value 19, respectively, during the stretching operation.
  • a winding-stretching selector switch shows how the guide value is conducted by the adjusting member 18 to the basic speed guide value 14, so that the guide value 19 dependent on the diameter and the guide value 19' dependent upon the tensile strength may be attained.
  • the diameter dependent guide value 19 is added opposed to the basic speed guide value 14.
  • the basic speed guide value 14 resulting at the rectifier 13 produces during the wind-up operation on the winding drive motor 21 of a winding body 22 a corresponding rate of revolutions by means of the electronic setting member 15.
  • the basic speed guide value 14 alone is effective because the guide value 19 dependent on the diameter is still zero and the stator 7 still has the tendency to rotate in the opposite direction of rotation of the rotary control body 10.
  • the stator 7 accordingly will be found in the left stop position and supplies the adjusting member 18 the value zero.
  • the guide value 19 dependent on the diameter is in this case not yet in effect.
  • the guide value 19 dependent on the diameter is directed opposite to the basic speed guide value 14 coming from the adjusting member 18 and influences the setting member 15 of the Winding drive motor 21 in such a manner that the tensile force in the winding material 23 between the rotary control body 10 and the wind-up-body 22 is constantly regulated.
  • the winding body 22 is connected by a coupling 24 with the winding drive motor 21, whose energization takes place over the setting member 15 directly from the power supply.
  • a rope pulley 25 which forms with the weights 26, 27 disposed on both sides a torque dynamometer.
  • the adjustment of the torque dynamometer takes place in such a manner that the stator 7 when the rotary body 10 runs empty, namely without any winding material 23, remains fixed in any desired position of the possible rotary movements.
  • the Weight of the torque dynamometer In order to obtain a predetermined tensile force between rotary control body 10 and Wind-up-body 22, there has to be added on the side of the rotary control body 10 opposite to the direction of rotation, to the Weight of the torque dynamometer an additional weight 28 corresponding to the tensile force in the winding material 23.
  • the rope pulley 25 is interchangeably mounted and is exchangeable by others whose circumference have a different cam shape, so that for the production of satisfactory windings a particular shape of the cam-like periphery is employed according to the structure of the material to be wound up and the tensile force applied thereto.
  • the peripheral shape of the rope pulley 25 which is attached before the commencement of the winding operation influences the variable tensile strength in dependency on the resulting winding diameter.
  • a switch 29 is disposed, which supervises the functioning of the control drive during the operation and indicates any disturbance, if the tension in the winding material set by the torque dynamometer between rotary control body 10 and the winding body 22 is not maintained on account of a disturbance and the stator 7 stands at one of the two stop positions.
  • the combined arrangement of the stretching operation and the subsequent winding operation for the spin-stretch winding is shown in FIG. 3.
  • the winding material 23, as for example, threads, coming from a spinning nozzle 30 is positively seized by the rotary control body 31 with the central basic speed determined by the frequency f1 of the synchronous generator 5 and is conducted to a rotary stretching body 32, is positively seized by the latter and conveyed to the rotary control body and then is conveyed to the wind-up-body 22.
  • a synchronous generator 34 coupled to the stretching motor 33 produces a voltage with the frequency f2, which, however, upon starting the spinning operation is the same as the frequency f1. Accordingly the circumferential speed of the rotary control body 10 is the same, as the latter is driven by the synchronous generator 34 with f2 equal to 11, and whereby with the described tension control device also the speed of the winder is adjusted to this value.
  • the stretching operation is introduced by means of the mechanically or electromagnetically increasing load represented by the additional weight 2 8 acting upon the weight 27' on the pulley 25' of the rotary control body 31.
  • the stator of the reaction adjusting motor *8 of the rotary control body 31 rotates in the direction of rotation, whereby the tension dependent guide value 19 becomes effective and greater.
  • the total guide value 20' becomes greater and the speed of the stretching motor 33 is accelerated until the condition of equilibrium between the tensile force in the material between the rotary control body 31 and the rotary stretching body 32 and the existing tensile force is attained through the additional weight 28' acting on the pulley
  • the synchronous generator 34 driven by the stretching motor 33 of the rotary stretching body 32 supplies by the slip rings 6 electric current to the reaction adjusting motor '8 of the rotary control body 10, which thereby takes up the stretched winding material with the same speed for winding it upon the winding body 22.
  • the basic speed guide value 14 produced by the synchronous generator 34 with the frequency f2 and the diameter dependent guide value 19 are arranged oppositely, so that with increasing diameter of the winding the total guide value 20 transmitted to the setting member 15 becomes smaller, so that the rate of revolutions of the winding drive motor 21 is decreased.
  • motor-driven rotary bodies over which the winding mate- rial, such as threads, bands, foils and the like, is guided and conveyed by a motor-driven rotary stretch body (31) and a motor-driven rotary tension control body (10) to a motor-driven rotary wind-up body (22), automatically adjustable tension control means associated with the motor-driven rotary stretch body and tension control body for obtaining an optimal build-up of the Winding on said wind-up body, said automatically adjustable tension control means operating in accordance with two electrically produced guide values which are independent of one another, means for producing said electrical guide values, said tension control means being adjustable in accordance With the stretch ratio of the winding material to be wound up and in accordance with a tension which is variable in relation to the changing diameter of the winding formed on said wind-up body, a motor (8) for driving said rotary stretch body (31) and a motor ('8) for driving said rotary tension
