Definitions

  • ABSTRACT Open-end spinning machine with spinning units each provided with a timing device for timing the spinning units in case of removal of temporary conditions. for instance, in remedying thread breakages.
  • Said timing device comprises correcting regulating elements for the individual adjustment of the time constants of each spinning units; a common regulating element for the simultaneous adjustment of the time constants of all the spinning units according the currently required spinning conditions of the spinning machine is preconnected to the timing devices of individual spinning units.
  • This invention relates to open-end spinning machines equipped with spinning units each provided with a timing device for timing the spinning units in case of the removal of some temporary condition, such as, for instance, remedying thread breakage.
  • the adjustment of the required time constants varies, of course, for different working conditions of the machine, for different yarn counts, take-off and feeding speeds, etc.
  • the individual spinning units have never exactly equal parameters, such as, for instance, the time constant of the feed roller clutch, the sensor sensibility and the like, due to tolerances in manufacture, adjustment of clutches, different characteristics of various materials, and so forth.
  • timing devices include correcting regulating elements for the separate, individual adjustment for the time constants of each spinning unit, and a common regulating element preconnected to the timing devices of individual spinning units, for the simultaneous adjustment of the time constants of all spinning units according to the current spinning conditions of the spinning machine.
  • the time control circuit comprises a voltage-dependent transistor circuit fed by a common supply source, with a correcting and with an operating relay to which the time controlled operating elements of spinning units are connected, while the time control circuit together with the other time control circuit of the spinning units are connected to a common regulating element of a common supply source.
  • FIG. 1 is a simplified block wiring diagram of spinning units on the machine, their timing devices and their common source of the supply voltage;
  • FIG. 2 is a block wiring diagram of a spinning unit
  • FIG. 3 is a wiring diagram of a time control circuit.
  • An open-end spinning machine 1 is provided with a number of spinning units 2 including well-known, devices (not shown) for separating fibers, such as a feed roller, a combing-out cylinder, a channel for conveying separated fibers and a twisting mechanism such as, for instance, a spinning chamber; further, there is provided some arrangement for yarn take-off and wind-up, control sensors and operating devices 21 for removal of a temporary condition of the spinning unit, for instance for remedying thread breakage, comprising clutches controlled in a predetermined time sequence by timing devices 3 interconnected to the sliver feeding drive, to the yarn take-off, and to the device for reversing the yarn take-off and wind-up.
  • the spinning units 2 are further provided with respective drives, such as the drive for thefeed roller, the drive for the combing-out cylinder, the drive for the twisting mechanism and the drive for other elements such as cleaning devices for removal of dirt and the like.
  • the timing device 3 of each spinning unit 2 com prises a correction regulating element 31, such as, in the case given, a variable resistor designed individually to adjust the time constant of each spinning unit 2.
  • a common regulating element 41 through which all the time control circuits of the spinning units 2 are supplied from a common supply source 4.
  • the common regulating element 41 which can be for instance, a multiposition switch for adjustment of the voltage U2 in steps, or a potentiometer of a regulating supply circuit of the common supply source 4.
  • the contacts P2 of an operating relay P connected in the course of operation of the time control circuit within the time interval determined by the time constants, are connected to time controlled operating elements 21 of the spinning unit 2, as for instance to a clutch interposed in the drive of the feed roller 22 and designed to interrupt, while removing temporary conditions, such as during the automatic correction of thread breakages, the feeding of the sliver to the combing-out cylinder for an exactly predetermined time interval in an exact time sequence with other switching operations.
  • the transisors T1 and T2 of the time control circuit are non-conductive under stationary conditions.
  • the capacitor C1 is charged to the voltage U2.
  • a starting contact 32 of, for instance, a sensor (not shown) or of a program transmitter for removing temporary conditions controlled by the sensor
  • the time control circuit starts its operation
  • the transistor T1 becomes conductive and the capacitor C1 charged to the voltage U2 is discharged through the transistor T1 and the variable resistor 31 and is again charged to the voltage U1 of opposite polarity via said variable resistor 31.
  • the diode D1 is opened and thus also the transistor T2 becomes conductive, the relay P is attracted and is held in this condition by its own contact P1.
  • the transistor T1 becomes nonconductive and the capacitor C l is again charged to the voltage U2 the relay P is released by disconnection of the starting contact 32 and the time control circuit is again ready for operation.
  • the supply source U1 is a source of constant voltage, designed to feed the operating section of the timing device.
  • the supply source U2 is a source of a variable voltage, feeding the regulating section of the timing device. lt is possible simultaneously to control, by way of the common regulating element 41, all the timing devices and thus also the operating of all spinning units, and also to control the timing device of each spinning unit individually by way of the regulating element 31.
