Definitions

  • the invention relates to a drafting system for a spinning machine, in particular for a regulating section for cotton, with at least two successive pairs of rollers, each of which has a roller driven by its own electric motor, and with an electronic control device that adjusts the speed of at least one of the electric motors to compensate for irregularities processing fiber association regulates.
  • the driven rollers are assigned locking means which are intended to prevent unwanted rotation of the rollers when the machine is at a standstill, due to the distortion tension of the fiber structure to be processed or due to electronic drifting or else from others Reasons.
  • the invention has for its object to design a drafting system of the type mentioned with the simplest possible means so that a turning back of the rollers is ruled out at a standstill.
  • This object is achieved in that at least one freewheel is assigned to the rollers driven by the one electric motor and at least one further freewheel is assigned to the roller or rollers driven by the further electric motor. Because of this design, it is possible to reliably prevent the rollers from turning back without the use of wear-prone components such as brakes or the like.
  • a common transmission shaft which is assigned a freewheel, is expediently arranged between the one electric motor and at least two driven rollers.
  • a freewheel is arranged in the main drive train for two driven rollers, which is simple in terms of the system.
  • This freewheel also blocks all rotary movements upstream.
  • the arrangement has the further advantage that there is structurally sufficient space for the arrangement of the freewheel at this point.
  • the freewheel replaces a ball bearing.
  • a freewheel is preferably assigned to each driven roller.
  • the freewheel is preferably arranged coaxially with the roller. In this way, possible play is reduced or avoided by additional gear stages, gear wheels, toothed belts or the like.
  • the freewheel is advantageously arranged axially parallel to the roller. This allows a freewheel to be used for more than one driven roller.
  • An electronic motor control device which is connected to the electronic machine control device, is expediently assigned to each electric motor.
  • a tachogenerator which is connected to the associated electronic motor control device, is preferably assigned to each of the electric motors.
  • the electronic motor control devices are each adjusted in such a way that the setpoints given by the electronic machine control to the motor control devices during standstill result in a counter torque of the electric motors in the direction of rotation opposite to normal operation.
  • Signals determining the rotation of the electric motors are expediently input by the electronic machine control device into the motor control devices.
  • the electric motors are preferably AC servo motors.
  • the electronic control device to compensate for irregularities with a measuring element, for. B. tongue and groove roller pair, in connection.
  • a common electronic control and regulating device for. B. a microcomputer used.
  • the freewheel is a sprag freewheel, which preferably forms an integral part with a ball bearing.
  • the sprag freewheel locks automatically and immediately at the lowest torque in the reverse direction.
  • a drafting system for a spinning machine in particular for a regulating section for cotton, with at least two successive pairs of rollers, each having a roller driven by its own electric motor, and with an electronic rule device that controls the speed of at least one of the electric motors to compensate for irregularities in a sliver to be processed, each associated with the driven rollers a rotation against their operational direction blocking freewheel.
  • a device which, when stopped, applies a voltage to the electric motors, the direction of rotation of which is opposite to the direction of rotation of a voltage applied during normal operation, the level of the control voltage emitted during the shutdown being expediently chosen such that electronic drifting in the operational sense of rotation of the electric motors 14, 17 is excluded.
  • the control voltage emitted when the motor is stopped is advantageously approximately -1 mV.
  • a device which applies a voltage to the electric motors when the motor is at a standstill, the direction of rotation of which is opposite to the direction of rotation of a voltage which is applied during normal operation, the level of the control voltage emitted at a standstill preferably being selected such that electronic drift in the operational mode Direction of rotation of the electric motors 14, 17 is excluded.
  • a rotation of the rollers is thereby excluded with certainty, since on the one hand the control voltage mentioned above counteracts the direction of rotation in the operating direction, and on the other hand the freewheel counteracts the direction of rotation in the opposite direction.
  • the control voltage emitted at standstill is expediently approximately -1 mV.
  • the freewheel is advantageously arranged in a gear stage.
  • the freewheel is preferably assigned to the input lower roller.
  • the freewheel is expediently integrated in one of the electric motors.
  • the regulating drafting system shown in FIG. 1 has an input roller pair 10, 10 ', a middle roller pair 11, 11' and an output roller part 12, 12 ', of which the input lower roller 10, the middle lower roller 11 and the output lower roller 12 are each driven.
  • These lower rollers 10, 11, 12 are assigned freely rotatable upper rollers 10 ', 11', 12 'which are loaded with adjustable pressing forces (see FIG. 1b).
  • the input lower roller 10 and the middle lower roller 11 are connected to one another via a gear stage, the translation of which corresponds to a predetermined preliminary delay.
  • the middle lower roller 10 and thus also the input lower roller 11 are driven by an electric motor 14.
  • the electric motor 14 is followed by a freewheel 49, which prevents the input lower roller 10 and the middle lower roller 11 from rotating against the direction of travel (arrow direction A) of a sliver 16 to be processed.
  • the output roller 12 is driven by its own electric motor 17.
  • a freewheel 18 is arranged between this electric motor 17 and the output lower roller 12, which also blocks rotation of the output lower roller 12 against the running direction (A) of the sliver 16.
  • the speeds of the electric motors 14 and 17 are controlled by means of an electronic control device so that on the one hand in the main draft zone between the middle roller pair 11, 11 'and the output roller pair 12, 12' there is a delay to the desired fineness, while at the same time mass fluctuations of the incoming sliver 16 so be balanced as much as possible.
  • a common transmission shaft 30 is present between the electric motor 14 and the two driven rollers 10 and 11, to which the freewheel 49 is assigned.
  • the common continuous transmission shaft 30 realizes a branching, wherein the electric motor 14 drives the transmission shaft 30 directly and then branches off from the transmission shaft 30 indirectly downstream of the two rollers 10 and 11.
  • the gear stages or transmission stages with toothed belts to the roller 10 on the one hand and to the roller 11 on the other hand are advantageously adjustable in this way.
  • a freewheel 50 is present between the electric motor 17 and the output lower roller 12.
  • the freewheels 49 and 50 are arranged axially parallel to the rollers 10, 11 and 12, respectively. With 31 to 41 gears or toothed belt wheels are designated. With 42 to 46 timing belts are designated. With A the fiber material flow in the working direction is indicated.
  • each electric motor 14, 17 is assigned an electronic motor control device 51 or 52 (speed control), which are connected to the common electronic machine control device 53.
  • the electric motors 14, 17 are each assigned a tachometer generator 54 or 55, which with the associated electronics
  • the engine control device 51 or 52 is connected.
  • the electronic motor control devices 51, 52 are each electrically adjusted in such a way that the setpoints 56 and 57 for the speed and direction of rotation given by the electronic machine control device 53 to the motor control devices 51, 52 for the speed and direction of rotation are a torque of the electric motors 14 and 17 in the normal operation (see arrows C to H in Fig. 1b) result in opposite direction of rotation.
  • a common electronic control and regulating device e.g. B. a microcomputer can be used, which comprises the machine control device 52 and the (not shown) electronic control device for compensating for irregularities.
  • a transducer which converts deflections of the grooved roller pair 25 into electronic signals.
  • the electronic motor control devices 50, 51 are each adjusted in such a way that the setpoints 53, 54 given when the motor is stopped tend to give the motors 14, 17 a slight direction of rotation which is opposite to normal operation, but rotation by the freewheels 15, 18, 47, 49, 50 is prevented. In this way, a lead lock is implemented.
  • the lower rollers 10, 11, 12 have a speed z. B. of 1400, 2000 or 7200 rpm and a diameter z. B. of 35 mm, 35 mm or 40 mm.
  • the belt running speed is approximately 900 m / min at the speed of 7200 rpm of the lower roller 12.
  • the freewheels 15, 18, 47, 49, 50 only allow the rollers to rotate in one direction, i. H. in the forward direction C to H (see FIG. 1b) during operation. After the drafting system has come to a standstill, the freewheel prevents the rollers from rotating backwards.
  • the balls lie in a solid cage which, according to FIG. 3, simultaneously guides a number of individually sprung clamping bodies 65. Due to their geometric shape, the clamping bodies 65 have a "lifting tendency" in the freewheeling direction I, which leads to the rings (inner ring 66 and outer ring 67) at high speeds up to the point of complete freedom from contact. It is important to have a sufficient relative cage speed from a sufficient radial load on the bearing.
  • This sprag freewheel 15, 18, 47, 49, 50 works continuously and non-positively.
  • the clamping bodies 65 lift off in the freewheeling direction I (forward direction) due to the centrifugal force.
  • the return direction K there is a clamping action and thus the locking action due to the pressure of the spring 68 of the clamping body 65 against the rings 66, 67.
  • the inner ring 66 is fixed, for. B. as a press fit, arranged on the drive shaft (z. B. for the lower rollers, whereby the locking action against the drive shaft occurs.
  • the outer ring 67 does not rotate.
  • Fig. 3a shows a section of a sprag freewheel, in which the clamp body 65 abut the rings 66, 67, so that the return in the direction K is blocked.
  • 3b and 3c show the combination of a sprag freewheel with a ball bearing.
  • the clamp body 65 are lifted from the rings 66, 67, i. H. the freewheel rotation I is shown. With 69 the balls are designated.
  • the invention is illustrated using the example of a sprag freewheel, but also includes other frictionally acting freewheels, e.g. B. Pinch roller freewheels. Furthermore, the invention includes both unsupported freewheels in which the shaft by separate bearings, for. B. roller bearings is stored as well as mounted freewheels (combination), in which the freewheel and z. B. the rolling bearing (ball bearing, cylindrical roller bearing, needle bearing, barrel bearing) form an integral component (Fig. 3b, 3c).
  • the backstop in the form of the freewheels 15, 18, 47, 49, 50 solves the task of excluding the turning back of the rollers when the machine is at a standstill; the turning back practically always occurs and is particularly caused by a relaxation of the slivers and the drive belts.
  • the advance lock in the form of the counter-torque for the electric motors 14, 17 has the further advantage that the undesired forward rotation of the rollers is eliminated when the machine is at a standstill; the forward rotation only occurs if the motor control devices 51, 52 (drive system) are not exactly adjusted to ⁇ 0, i. H. the forward turning can occur.
  • the desired adjustment is in itself present when the electric motor 14, 17 is at a setpoint 56, 57 of zero. During operation, however, there may be a deviation from the zero adjustment and thus electronic drift in the forward direction, which is avoided by the counter torque.
  • the regulating drafting system shown in FIG. 4 of the drawing has an input roller pair 10, 10 ', a middle roller pair 11, 11' and an output roller pair 12, 12 ', each of which is the input gear lower roller 10, the middle lower roller 11 and the output lower roller 12 are driven.
  • These lower rollers are assigned freely rotatable upper rollers 10 ', 11', 12 'which are loaded with adjustable pressing forces.
  • the input lower roller 10 and the middle lower roller 11 are connected to one another via a gear stage 13, the translation of which corresponds to a predetermined preliminary delay.
  • the middle lower roller 11 and thus also the input lower roller 10 are driven by an electric motor 14.
  • a freewheel 15 is arranged between the electric motor 14 and the central lower roller 11, which blocks rotation of the central lower roller 11 and thus also the input lower roller 10 against the running direction (arrow direction A) of a fiber structure 16 to be processed.
  • the output lower roller 12 is driven by its own electric motor 17.
  • a freewheel 18 is arranged between this electric motor 17 and the output lower roller 12, which also blocks rotation of the output lower roller (12) against the running direction A of the fiber structure 16.
  • the speeds of the electric motors 14 and 17 are controlled by means of an electronic control device 19 so that, on the one hand, in the main draft zone between the middle roller pair 11, 11 'and the output roller pair 12, 12' there is a delay to the desired fineness, while at the same time mass fluctuations of the incoming fiber structure 16 be balanced as much as possible.
  • These fluctuations in the mass of the fiber structure are detected by means of a detector device arranged in front of the pair of input rollers 10, 10 'and input as a control signal 20 into the electronic control device 19.
  • the detector device is formed by a pair of grooved rolls 25 known per se, which is driven by the input lower roll 10 and thus by the electric motor 14 via a toothed belt drive 26.
  • the electronic control device 19 supplies the frequency converters 27, 28 connected upstream of the electric motors 14, 17 with a control voltage of 0 V to approximately 10 V, so that exact control is possible even in the range of low speeds.
  • the frequency converters 27, 28, which are connected to a three-phase power supply 21 with 380 V and mains frequency, supply the electric motors 14, 17 with a frequency and three-phase voltage that are dependent on the applied control voltages.
  • the electronic control device 19 is provided in a manner not shown with a start and stop device, the signal, which is indicated by an arrow 22, is input into the electronic control device 19. In the event of a stop signal, the electronic control device 19 moves the control frequency of the electric motors 14, 17, which are designed as synchronous motors, to 0.
  • the electronic components of the electronic control device 19 do not cause a complete interruption of voltages and currents, like a mechanical switch, there is a risk of a so-called electronic drift, i. H. the occurrence of a small torque that tries to turn one or both electric motors 14, 17.
  • a so-called electronic drift i. H. the occurrence of a small torque that tries to turn one or both electric motors 14, 17.
  • the electronic control device 19 after the frequency-controlled shutdown, swaps a low control voltage to the frequency converter of the electric motors 14, 17 and then supplies the low voltage and thus reverses the direction of rotation compared to the direction of rotation during normal operation.
  • the electric motors 14, 17 are loaded with a - relatively low - torque against their normal working direction, so that they "lean” against the freewheels 15, 18. This also prevents unwanted twisting of the lower rollers 10, 11, 12 in the normal running direction (A) of the fiber structure.
  • the freewheel 15 can also be arranged at a different location than between the electric motor 14 and the central lower roller 11.
  • it can be arranged in the gear stage 13 or can also be assigned to the input lower roller 10.
  • the freewheel 15 could also be integrated into the electric motor 14.
  • it is also not necessary to arrange the freewheel 18 between the output lower roller 12 and the electric motor 17.
  • this freewheel can also be integrated into the electric motor 17.
