Definitions

  • the present invention relates to a system for feeding the electric power to motors for use in a textile machine. More particularly, the present invention relates, in a textile machine, such as a spindle drive type fine spinning frame, including a plurality of spindles and a large number of draft rollers, to an electric power feeding system for a textile machine of a single spindle drive type which comprises spindle motors for driving individually a plurality of spindles.
  • a textile machine such as a spindle drive type fine spinning frame, including a plurality of spindles and a large number of draft rollers
  • a spindle drive portion and a draft drive portion are separately included therein, and in many cases, the spindle drive portion for driving a plurality of spindles utilizing a single spindle is constituted of discrete drive motors such as D.C. brushless motors and also the draft drive portion is constituted of an inverter or a servo motor.
  • the three-phase commercial A.C. power source voltage of 380 to 460 V is converted into the D.C. power source voltage through a chopper power source 10 and the resultant D.C. power source voltage is supplied to a draft inverter 20 for a draft motor 30 as well as to each of spindle motors 50 through a large number of motor drivers 40.
  • the three-phase power source voltage of the 400 V class is inputted as the A.C. power source voltage to the chopper power source 10 common to the draft motor 30 and each of the spindle motors 50, then the D.C. output voltage from the chopper power source 10 is inputted to both of the draft inverter 20 for the draft motor 30 and each of the drivers 40 for the discrete spindle motors 50 such as the D.C. brushless motors.
  • the spindle motor 50 has a small capacity. Then, if these spindle motors 50 and the power devices as the motor drivers 40 are made the high-voltage withstanding elements, these high-voltage withstanding elements become expensive. Therefore, the D.C. voltage outputted from the chopper power source 10 is reduced through the chopper. For this reason, the D.C. voltage which is supplied from the common chopper power source 10 to the draft inverter 20 also becomes the low voltage.
  • an object of the present invention is to provide a system for feeding the electric power to motors for use in a textile machine in which products for various purposes are enabled to be used as a draft motor and a draft inverter for driving the draft motor to reduce the installation cost.
  • a system for feeding the electric power to motors for use in a textile machine which serves to feed the electric power to both of a plurality of spindle motors for driving individually a plurality of spindles and a draft motor for driving a draft roller
  • the system comprising: a converter portion for rectifying an A.C. current that has been obtained from an A.C. power source into a D.C. current; and a chopper portion for adjusting the output voltage of the D.C. current that has been obtained by the conversion in the converter portion, the electric power which has been outputted from the converter portion being fed to the draft motor, the electric power which has been outputted from the chopper portion being fed to the plurality of spindle motors.
  • Fig. 2 is a block diagram showing a circuit configuration of an electric power feeding system of an embodiment 1 according to the present invention.
  • a three-phase commercial A.C. power source of 380 to 460 V is connected to a chopper power source 1.
  • the chopper power source 1 includes a converter portion 8 for rectifying an A.C. current that has been obtained from the A.C. power source into a D.C. current, and a chopper portion 4 for adjusting the output voltage of the D.C. current that has been obtained by the rectification in the converter portion 8.
  • the chopper portion 4 comprises: a reducing chopper 4a for reducing the D.C. power source voltage that has been obtained by the rectification in the converter portion 8; a boosting chopper 4b for boosting the D.C. power source voltage that has been obtained by the rectification in the converter portion 8; and a controller 4c for carrying out the switching control for the reducing chopper 4a and the boosting chopper 4b.
  • the chopper portion 4 is connected to each of spindle motors 6 through the respective motor drivers 5.
  • the controller 4c carries out the control in such a way that, with respect to the reducing chopper 4a and the boosting chopper 4b, in the power running, the reducing chopper 4a is operated at the time when the voltage on the load side starts to drop, and in the regeneration, the boosting chopper 4b is operated at the time when the voltage on the load side starts to rise.
  • the D.C. power source voltage which has been obtained by the rectification in the converter portion 8 of the chopper power source 8 is supplied to the draft motor 3 through the draft inverter 2.
  • the A.C. current is rectified in the converter portion 8 and then the D.C. current component which has been taken out in the converter portion 8 is supplied to the draft inverter 2. Therefore, the products for various purposes of, for example, the 400 V class (or the 200 V class when the input A.C. voltage is in the range of 200 to 220 V) which corresponds to the A.C. power source voltage can be used as the draft motor 3 and the draft inverter 2 so that the cost of the draft motor 3 and the draft inverter 2 can be remarkably reduced.
  • the D.C. power source voltage which has been obtained by the reduction of the original voltage in the chopper portion 4 of the chopper power source 1 is supplied to each of the motor drivers 5 of respective spindles which are driven by the single spindle.
  • the dedicated motor since each of the spindle motors 6 is the product specially made to order, i.e., the dedicated motor, even if such a D.C. power source voltage obtained by the reduction of the original voltage is used, there is no need to worry about a sudden rise in the price caused thereby.
  • the D.C. power source voltage obtained by reducing in the chopper portion 4 is reduced too much, then the feeding current to each of the motor drivers 5 is increased so that the diameter of the feeding line becomes large. For this reason, it is proper that the power source voltage of about D.C. 150 V with which the pass device withstanding the D.C. 250 V can be used is supplied to each of the motor drivers 5.
  • the boosting chopper 4b is provided in parallel with the reducing chopper 4a that operates in the steady running so that the regenerative energy from each of the spindle motors 6 can be withdrawn to the converter portion 8 in stopping operation, whereby each of the spindles which are coupled to the respective spindle motors 6 can be stopped with the suitable slowdown gradient in the interruption of the active power supply.
  • the regenerative energy is generated by each of the spindle motors 6, whereby the draft roller can be stopped synchronously with each of the spindles without exhausting the energy of the draft motor 6.
  • the power source voltage which is obtained by the reduction of the original voltage in order to drive spindles is not supplied to both of the draft inverter for driving the draft motor and the draft motor, but the power source voltage corresponding to the commercial A.C. power source voltage is supplied thereto. Therefore, the power source voltage which is supplied to both of the draft motor and the draft inverter is not excessively reduced and hence the inexpensive products for various purposes can be used as the draft motor and the draft inverter. Hence, it is possible to reduce the installation cost of the textile machine.
  • the conventional synchronous stopping method can be adopted by providing the chopper power source for the spindle motors with the regeneration function.
