Definitions

  • the invention relates to a spinning machine, the auxiliary units of which at least the driven cylinders of the drafting system and the ring rail are provided with individual drives each formed by an electric motor, the speeds of which can be set independently of one another.
  • the individual drives of the auxiliary units as well as those of the spindles are each formed by a synchronous motor or asynchronous motor.
  • Those of these motors which drive the cylinders of the drafting system and the ring bench, are each connected to a converter, the output frequency and output voltage of which can be set independently of one another.
  • the only actual value available here is a clock generator which is coupled to the delivery cylinder via a gearbox and which supplies the control frequency for those converters to which the An drive motors of the other auxiliary units are connected.
  • the invention has for its object to provide an improved spinning machine. This object is achieved by a spinning machine with the features of claim 1.
  • the solution according to the invention which is particularly suitable for spinning testers, but also offers advantages, for example in the production of special yarns, such as fancy yarns, not only enables exact synchronization of the individual drives even when the setpoints, thanks to the actual value signals supplied by the angle encoders are different.
  • the setpoint of the speed and the angular position can therefore be maintained with the same accuracy as with piecing programs and spinning programs as when operating the machine with the main spindle speed.
  • a speed program and / or angular position program that is completely independent of the other programs can be specified for all motors and that the programs can also be changed during operation.
  • the ring bench movement can be varied, not only with regard to the stroke and the advancement, but also with regard to the time course of the stroke movement.
  • the spindle speed can be varied depending on the ring bench position, in particular can be changed between a maximum and a minimum speed.
  • the individual drives for the carrier rails are also Balloon containment rings and the thread eyelets as well as their angle transmitters are connected to the positioning processor so that the movement of these auxiliary units can also be regulated according to your own programs.
  • the electric motors of the individual drives are preferably electronically commutating motors. However, other electric motors that enable precise positioning are also possible.
  • resolvers are provided as angle transmitters which have a very high angular resolution, for example approximately 1,000 steps per revolution.
  • other high-resolution angle encoders are also suitable.
  • the positioning processor preferably has at least one output for a converter control signal because, in the spinning machine according to the invention, the spindles are preferably also provided with individual drives which are connected to a controllable converter. If at least one of the spindles is provided with a speed probe, the actual value given by this speed probe can be fed to the positioning processor. Based on the actual value / setpoint comparison, this can then form the converter control signal.
  • the positioning processor has a connector for a personal computer. Programs can be conveniently entered into the positioning processor using this personal computer, and program changes can also be made during operation.
  • the position processor has a memory for at least one setpoint program, so that the personal computer does not have to be constantly connected to the positioning processor.
  • the positioning processor advantageously has an input for a "ring bank above” and / or a "ring bank below” signal. Furthermore, inputs for a start signal and a stop signal are expediently provided in order to be able to start a program manually and also to be able to manually stop the spinning machine.
  • a spinning machine has a drafting system consisting of a delivery cylinder 1, an apron cylinder 2 and two further cylinders 3 and 4 together with the associated pressure rollers, which feeds the starting material. Since the speeds usually increase from cylinder 4 to delivery cylinder 1, the material to be processed experiences a first advance between cylinder 4 and cylinder 3, a second advance between cylinder 3 and apron cylinder 2, and between apron cylinder 2 and delivery cylinder 1 a major default.
  • spindles 5 of the same design are arranged at a distance from one another, onto each of which a sleeve can be attached, which rotates together with the spindle 5 in the attached state.
  • the thread eyelets 6 are carried by a support rail 9 that can be moved up and down, the balloon containment rings 7 by a support rail 10 that can also be moved up and down, and the ring / rotor assemblies 8 by a ring bank 11 that can be moved up and down.
  • the spindles 5 are driven by means of an asynchronous motor 12, to each of which a speed sensor 13 is coupled, which generates a frequency signal proportional to the speed.
  • Each of the cylinders 1 to 4 is driven by an electronically commutating motor 14.
  • These motors 14 are each provided with a resolver with a resolution of approximately 1,000 steps per revolution.
  • the drive motors 16, 17 and 18, by means of which the carrier rail 9 or carrier rail 10 or the ring rail 11 are moved in the vertical direction, are electronically commutating motors in the exemplary embodiment.
  • These motors are also each provided with a resolver 19, which are designed like the resolvers 15.
  • the control of the electronically commutating motors 14 and 16 to 18 takes place via an amplifier 20 from a positioning processor 21.
  • the latter also supplies the control signal for a converter 23 to which the asynchronous motors 12 are connected.
  • the output signals of both the speed sensor 13 and all resolvers 15 and 19 are fed to the positioning processor 21.
  • the positioning processor 21 which contains, among other things, a microprocessor, a RAM and an EPROM, compares the actual values supplied by the speed sensors 13 and the resolvers 15 and 19 with corresponding target values.
  • the sampling rate is approximately 0.2 milliseconds.
  • the positioning processor 21 can therefore quickly detect deviations of the actual values from the target values and eliminate deviations by a corresponding change in the control signals which reach the amplifiers 20 and the converter 23.
  • a spinning speed, a main spinning speed and a spinning speed are usually specified for a spinning program.
  • the time within which the speed changes are to be carried out can also be specified.
  • the speed programs for cylinders 1 to 4, for the ring bench movement and for the support rails 9 and 10 must be specified.
  • the changes in the spindle speed depending on the position of the ring rail can be prescribed.
  • the positioning processor 21 Since a spinning program must start at a defined ring bank position, the positioning processor 21 has two inputs for the signals "ring bank above” and “ring bank below", which are supplied by two sensors, shown schematically as switches 24 and 25. If a start switch 26 is actuated manually, the signal of which is also fed to the positioning processor 21, then, if necessary, the ring bank is first moved into the start position. Only then is every necessary program started and carried out automatically. The spinning machine can be brought to a standstill by means of a manually operated stop switch 27.
