Definitions

  • the invention relates to a can on a card, draw frame, carding machine or the like with an electromotive drive device which drives tape feed rollers arranged in the region of a sliver inlet opening and upstream sliver feed rollers, and has drive-less sliver guide rollers between sliver feed rollers and sliver feed rollers, the drive speeds of the sliver feed rollers and the sliver feed rollers in are an adjustable relationship to each other, the tape feed rollers are driven by an electric motor and the speed of the tape feed rollers is detected by a sensor of an electrical control device that controls or regulates the speed of the electric motor adjustable.
  • Pitcher sticks of the type mentioned are known. They are preceded by a card that feeds the sliver at a certain speed.
  • the card has the above-mentioned sliver delivery rollers, between which the sliver is passed.
  • the belt driven by the belt feed rollers runs via subsequent belt guide rollers to the aforementioned fiber bond inlet opening, which is followed by the belt feed rollers. From there, the tape is placed in a jug in order to the jug stick.
  • the mounting position of the can stock is fixed relative to the card. It can only be changed in position with considerable effort. Depending on the type and installation type of the machine supplying the sliver, an adjustment of the installation position of the can stick relative to the card is desired.
  • a device is known by means of which textile fiber tapes can be made uniform in terms of their thickness.
  • the sliver emerging from a spinning preparation machine is first passed through a drafting system.
  • the drafting system is composed of a first pair of drafting rollers running at a constant speed and a second pair of drafting rollers arranged behind it, the speed of the second pair of drafting rollers being able to be changed in order to equalize the fiber cross section.
  • a draft adjustment device is provided, to which the speeds of both pairs of drafting rollers detected with tachogenerators are fed.
  • the relevant speed signal is also fed to the drive motor of a can stick, so that its drive speed is largely adapted to the speed of the drafting system.
  • the sliver passes through a sliver store which is provided with two light barriers which control the fill level of the sliver accumulated in the sliver store.
  • the light barriers pass on the signals determined by means of a two-point control to a level control device that operates the drive motor of the can attachment faster or slower.
  • the invention has for its object to provide a can of the type mentioned, which allows easy fiber bond transport with a simple design.
  • only relatively small drive powers should be required and it should be possible to move very quickly at maximum speed after the threading phase of the sliver.
  • At least one of the tape guide rollers for forming a sliver loop is arranged displaceably as a function of the tape tension and that the respective shift position can be detected by an electrical measuring device and can be supplied as a control variable to the electrical control device for fine-tuning the speed ratio, the which Measuring device associated tape guide roller is mounted on a dancer device.
  • the speed ratio between the tape feed rollers and the tape feed rollers is determined by the respective Speed of the conveyor rollers controlled.
  • the coupling of these two drives is implemented electronically.
  • the strip delivery rollers are connected to a sensor which emits an output signal in accordance with the speed in each case.
  • This output signal is fed to an electrical control device which is connected to the electric motor for driving the tape feed rollers.
  • the speed of the motor to be controlled can be set on the control device.
  • the set speed ratio between the tape feed rollers and the tape feed rollers is maintained in every operating state in that the speed control of the electric motor carried out by the control device takes place as a function of the output signal (sensor measured value) of the sensor.
  • the arrangement can be designed as a controller or as a regulator.
  • the respective actual state is determined and compared with a set target value. If there is a discrepancy between the actual and the target value, the speed of the electric motor controlled by the control device is changed until the desired target value has been reached. In the case of a control, on the other hand, occurring disturbance variables which can cause a deviation from the intended number of thirds are not taken into account.
  • the solution according to the invention has the advantage that no mechanical transmission elements but only an electrical connection is required between the card and the cane. This makes it possible to place the two machine components at any desired location depending on the space available and the requirements for the belt guide.
  • the components can be connected to one another via an electrical plug connection, so that assembly or disassembly is possible at any time without great effort.
  • the regulation and coordination of the speeds of the tape delivery rollers and the tape feed rollers is much simpler or is now only possible continuously, so that the overall tape quality is improved. Faults such as tape breaks etc. are minimized.
  • At least one of the sliver guide rollers for forming a sliver loop is arranged to be displaceable depending on the sliver tension and the respective shift position is detected by an electrical measuring device and fed to the frequency converter as a control variable for fine-tuning the speed ratio, changes in condition, e.g. during the stretching of the belt, can be detected at an early stage and be balanced. If, for example, the tape tension changes during operation and the tape guide roller is shifted, the electrical measuring device responds, which supplies a control variable to the frequency converter to eliminate the disturbance, as a result of which the output frequency of the frequency converter is increased or decreased accordingly.
  • the tape guide roller assigned to the measuring device is mounted on a dancer device which supports the displacement of the tape guide roller in such a way that an increase or decrease in the size of the sliver is followed.
  • the electric motor driving the tape feed rollers is a three-phase motor, which is connected to a frequency converter controlled by the sensor.
  • the speed of the three-phase motor can be set economically in a simple manner by means of the frequency converter, the control information for the speed setting coming from the sensor, which supplies a control signal as a function of the speed of the belt feed rollers.
  • the electric motor driving the tape feed rollers can e.g. be designed as an AC motor as well as a DC motor.
  • the construction is simple because the sensor is designed as a tachometer generator coupled to the belt delivery rollers.
  • the tachometer generator supplies an output voltage which is dependent on the speed of the strip supply rollers and is supplied as a control voltage to the frequency converter, which outputs a corresponding output frequency for operating the three-phase motor of the strip feed rollers. The speed of this three-phase motor is thus controlled via the frequency.
  • the tape guide roller is arranged on an end region of a dancer arm, which carries an adjustable counterweight at its other end region and is pivotably mounted between its end regions, the pivot axis being connected to a rotary angle encoder forming the measuring device.
  • the rotary encoder can preferably be designed as a potentiometer. Depending on the position of the counterweight, a correspondingly large sliver loop will occur during stationary operation. As soon as a change in the loop size occurs due to certain disturbance variables, the dancer arm is shifted (swiveling), as a result of which the position of the rotary encoder is changed. If this rotary encoder is a potentiometer, its resistance value changes, which is detected by the frequency converter. In response to this change in resistance, the frequency converter makes a change in its output voltage frequency, so that a corresponding strip tension is set via the resulting change in speed of the belt feed roller motor, which restores the normal operating state.
  • the measuring device is connected to the frequency converter via a PI controller.
  • the control behavior of this type of controller enables particularly quick and vibration-free intervention.
  • a turntable is provided for the rotation of a sliver receiving the sliver, which is driven by a belt drive gear with the electric motor of the tape feed rollers.
  • the sliver inlet opening of the jug can runs on a circular path above the jug, so that the sliver entering the jug is deposited in a circle. Superimposed on this movement, the jug rotates about the axis of the turntable, so that the jug can be loaded very evenly.
  • the electric motor driving the tape feed rollers preferably has a second shaft output, to which a reduction gear is preferably flanged, the drive shaft of which is connected to the belt drive gear.
  • the turntable is coupled to a separate electric motor.
  • This electric motor can preferably be a speed-controlled three-phase motor.
  • the three-phase motor is coupled for speed control with the electric motor of the tape feed rollers via an electronic adjusting device, the speed ratio of both motors being adjustable.
  • the invention is not limited to the use of three-phase motors and the use of frequency converters, since for example direct-current motors can also be used, the speed of which can be varied by means of corresponding control devices.
  • direct-current motors can also be used, the speed of which can be varied by means of corresponding control devices.
  • single-phase AC motors is also conceivable.
