Definitions

  • the invention relates to a yarn feeding device for circular knitting machines with stripers, which has Fadenleitrohre in a number per striping apparatus, which corresponds to the number of processable by the strands threads, wherein the Fadenleitrohre are each arranged between a receptacle for a bobbin and the Ringelapparat upstream Ringelfournisseur.
  • the present invention is therefore based on the object of proposing a yarn feeding device for rotary machines, with which all occurring yarn defects can be reliably detected and the rotary machine is timely switched off when an error occurs.
  • a yarn feeding device for circular knitting machines with stripers which has Fadenleitrohre in a number per striping apparatus, which corresponds to the number of processable by the strands threads, the Fadenleitrohre each between a receptacle for a bobbin and the Ringelapparat upstream Ringelfournisseur arranged and are provided with a thread sensor device, wherein the yarn sensor means of all a knitting point associated Fadenleitrohre are jointly evaluated by a monitoring device and wherein a stop signal for the machine control can be generated by the monitoring device upon detection of a thread error.
  • standard feeders can be used.
  • the cumbersome threading the threads in the Absteller of the known Spezialfournisseure can be omitted.
  • the detection of a thread error also takes place at a greater distance in front of a knitting point, so that a shutdown of the machine can be done in good time even with fast running machines.
  • Due to the parallel monitoring of all fed to a knitting yarns patterning errors can be detected in addition to thread breaks or thread ends.
  • the monitoring device can preferably be supplied with the pattern data of the knitted fabric by the machine control so that it can generate a stop signal for the machine control upon detection of a patterning error.
  • the thread guide tubes may have at least one thread deflection point and the thread sensor device may be arranged in the region of the deflection point.
  • the threads come thereby automatically against the sensor device in plant. It is particularly advantageous if the thread sensor devices are each arranged in a remote from the knitting portion of the Fadenleitrohre. The greater the distance between the sensor device and the knitting point, the longer the time available for stopping the machine.
  • the thread sensor devices may preferably comprise capacitive or optical sensors. Not only yarn breaks but also other yarn defects can be detected with these sensors.
  • the thread sensor devices should be able to monitor the presence of a thread in the thread guide tube and the thread movement in order to prevent knitting errors. Preferably, therefore, such sensor devices are used.
  • the thread sensor devices also monitor the thread quality.
  • the machine can also be turned off when, for example, thread thickening is detected.
  • the quality assurance can be further increased with the monitoring method.
  • the figure shows schematically a Fadenleitrohr 10, which is arranged between a creel 11 and a Ringelfournisseur 12.
  • the Fadenleitrohr 10 has two deflections 10.1, 10.2 by 90 °, wherein in the deflection of the feeder 12 12.2 further 10.2, a sensor device 13 is arranged with capacitive or optical sensors, not shown.
  • the sensor device 13 monitors whether there is a thread in the thread guide tube 10, whether the thread moves and whether the thread optionally has a thickening.
  • Each of the Ringelfournisseure 12 are so many Fadenleitrohre 10 associated with sensor devices 13 as a feeder 13 downstream of the feeder 14 can process threads.
  • the stripper 14 then performs each one of the threads of Fadenleitrohre 10 one or more knitting / n 15 a circular knitting machine.
  • more than one Ringelapparat 14 a knitting point 15 may be assigned to increase the number of possible colors.
  • the sensor devices 13 of all of a knitting point 15 associated Fadenleitrohre 10 are evaluated jointly by a monitoring device not shown here together. If the monitoring device detects a thread break, a thread end or a thread thickening in one of the thread guide tubes, it triggers a machine stop signal. In addition, a machine stop signal is triggered when in each Fadenleitrohr 10 is a thread, but moves none of the threads. Even then, a knitting error would occur during further operation of the machine, which can be avoided.
