Definitions

  • the invention relates to a method and a device for controlling the spinning units of a spinning machine, in particular an open-end spinning machine, the length determination of the wound yarn and the possibility of cleaning the individual spinning positions being improved.
  • a device for measuring the yarn spun in the respective spinning unit is known. After reaching a predetermined length of the wound yarn, the relevant spinning unit is switched off by interrupting the sliver supply, after which the bobbin fully wound there is replaced by an empty sleeve. Devices are also known which track the duration of the uninterrupted running of the individual spinning stations and switch off these spinning stations after a predetermined time has been reached, ie interrupt their course. The rotor can then be cleaned and the predetermined or necessary spinning time required to maintain the specified yarn quality can be determined or measured, the yarn quality being dependent on the duration of the spinning time. In both cases an electronic control system is used, which is activated by the switch-on signal of the spinning machine.
  • the output signals of the electronic control system can, for example actuate the electromagnetic coupling for the material feed (sliver feed).
  • a method for measuring the yarn length is described below.
  • the signal via the aisle of the spinning station is sent from the spinning station to the central electronic control system via a double busbar.
  • the signal for controlling the run of the spinning station is forwarded by the central electronic control system via the double busbar and secures the course of the respective spinning station with the aid of a switch located in the control circuit of the electromagnetic clutch.
  • a disadvantage of this device is, however, that even a brief fault can cause yarn breaks. This malfunction may have been caused by a defect in the central electronic system, the double busbar or a fault signal in the control circuit of the switches of the individual spinning stations. By unnecessarily switching off the respective spinning positions, there are production losses and excessive impairment of the yarn quality caused by excessive spinning.
  • the object of the invention is to implement a method and a device for controlling the spinning units of a spinning machine, the control units of the central electronic control system and parts or the entire double busbar being able to be tested and possibly replaced during the machine operation.
  • the principle of the method according to the invention is that the control of the spinning stations via the double busbar is blocked by a command from the central control unit and the operation of the spinning spinning stations is maintained by a reserve single busbar.
  • the reserve single busbar is connected to the electromagnets of the couplings of the spinning stations via isolating diodes and to the supply circuit via a load switch.
  • the control of the spinning system is secured by using the reserve single busbar.
  • the reserve single busbar can be activated if necessary by the operating personnel or after evaluation of the operating status by the central electronic control system. The activation by the operating personnel facilitates the monitoring and repairs of the spinning system, the electronically controlled connection increases the reliability of the system and its resistance to short-term disturbances.
  • the spinning machine contains a large number of spinning positions, each of which is equipped with an electromagnet 3 and components of the coupling for the material feed form. All parts assigned to a respective spinning unit are each identified by an index, for example electromagnet 3.1 to electromagnet 3.n.
  • a current source 1 is connected to the electromagnets 3.1 - 3.n via thread monitors or break sensors 2.1 - 2.n and switches 4.1 - 4.n.
  • a double busbar 5 is connected with the switches 4.1 - 4.n and the output of the break sensors 2.1 - 2.n.
  • a parallel reserve single busbar 8 connects the electromagnets 3.1 - 3.n via the isolating diodes 7.1 - 7.n and a load switch 9 to the current source 1.
  • the central control unit 6 is connected to the double busbar 5 and the load switch 9 through the input 10 for automatic control.
  • the load switch 9 is also provided with a manual control input 11.
  • FIG. 2 shows an embodiment variant of the device according to the invention.
  • the electromagnets (couplings) 3.1 - 3.n and the switches 4.1 - 4.n break sensors 2.1 - 2.n are interposed between the take-off and the winding 12.1 - 12.n.
  • Modules 13.1 - 13.n are formed from the groups of switches 4 and the parts of the double busbar 5 which correspond to them.
  • 8 assemblies 14.1 - 14.n are formed from the groups of the isolating diodes 7 and the parts of the reserve single busbar corresponding to them.
  • this state is evaluated by the central control unit 6.
  • the load switch 9 is then switched off via the input 10 for automatic control.
  • the switch 4 responsible is then also switched off via the double busbar 5.
  • the density of the yarn being spun is interrupted and, as a result, the corresponding break sensor 2 is switched off.
  • This state is also evaluated by the central control unit 6 and the load switch 9 is switched on.
  • the load switch 9 remains in the switched-on state until another spinning position has reached the predetermined yarn length.
  • the advantage of the described method and the device is that the complicated control circuits of the double busbar 5 and the associated actuated switches 4, in the time when they are not used to control the course of the spinning stations, are blocked and replaced by a reserve Single busbar 8 are replaced with increased resistance to interference and with increased reliability.
  • assemblies 13 and 14 consist of the switches 4 and each of a part of the double busbar 5.
  • the assemblies 14 consist of the isolating diodes 7 and the corresponding part of the reserve single busbar 8.
  • the three basic elements for interrupting the spinning process are the break sensors 2.1 - 2.n, the break sensors 12.1 - 12.n between the take-off and the take-up and the switches 4.1 - 4.n.
  • those sections of the device that affect the gait of the entire machine are particularly important. These sections include the switches 4 and the double busbar 5, while the sections with the sensors and the individual electromagnets 3.1 - 3.n only influence the operation of the individual spinning positions.
  • the load switch 9 can be switched on for the duration of the repair by activating the manual control input 11. During this time, a defective assembly can be replaced or tested without the machine having to be interrupted.
