Definitions

  • the invention relates to an apparatus and a method for monitoring a plurality of jobs of a ring spinning machine, according to the preambles of the independent claims.
  • the UTER Technologies AG system USTER ® RINGDATA is used to monitor a running sequence of work stations of a ring spinning machine for yarn breakage. For this purpose, in the jargon "Wandersensor” or “Wandermaus” called probe is guided past the jobs. The probe is equipped with a magnetic sensor for non-contact detection of the rotational movement of the ring travelers. The sensor picks up electrical signals that are generated when the threadline is correct and fail if there is no thread. This system is z. In US 4,122,657 A or in US Pat
  • cops are produced on a ring spinning machine. These cops are rewound to a downstream winding machine, for example, on larger cheeses. When rewinding the yarn passes through a yarn tester or yarn cleaner. Via an also present cop tracking system it is possible to specify on the basis of thread quality information supplied by the yarn tester which spinning station has produced the relevant yarn. For this purpose, the individual cops are provided with a suitable marker such as a bar code. At or next to the ring spinning machine a stationary reading device for the markings on the individual cops is provided, which is arranged in the region of a conveyor belt for the empty or wound cops.
  • a known automatic control which periodically passes through the jobs of a spinning machine and, if necessary, performs certain operations on a spinning station and, for example, notes yarn breaks.
  • a disadvantage of this known device is to be seen in particular in that the reading device is provided for the markings on the individual cops in the region of a conveyor belt for the cops, which allows the possibility of erroneous associations between spinning stations and markers on cops. In this arrangement, it is mandatory that the cops pass in such an order the reading device, which corresponds to the arrangement of the spinning stations on the spinning machine. This assignment can be disturbed if, for example, a cop falls off the conveyor belt. Thus, the correct cop tracking is no longer guaranteed.
  • EP-0'342'527 Al and US-4,660,370 A propose to identify the cop tube itself with unique codes or identification marks.
  • the codes can z. B. in the form of a bar code or a magnetic tape described.
  • the disadvantage of this solution is that a reader must be arranged for the coding at each spinning station, which is expensive and expensive in large spinning machines.
  • the individual spinning stations of a ring spinning machine are monitored by yarn cleaners in a winding machine connected to the ring spinning machine.
  • the signals of the yarn cleaner are evaluated in order to be able to draw direct conclusions about the spinning position that has produced the respective cop.
  • a writable information carrier on a caddy which transports the cop to the winder, described with appropriate information.
  • a reading device is arranged, which on the information carrier stored information about the ring spinning spindle, which has generated the cop reads. This read information is fed to the winding station computer at the beginning of the rewinding process, which carries out the linkage with the cleaner signals generated during the rewinding.
  • Similar methods teach EP-0'392'249 A2, US-4,838,019 A and US-5, 107,667 A. Again, there is a risk of incorrect assignment of the spinning stations.
  • the invention is based on the known system USTER ® RINGDATA.
  • this includes a "traveling mouse" with a motion sensor for detecting yarn breaks, the average rotational speed at the work stations and / or spinning stations at too low a speed Acquisition of identification data, which are applied, for example, as visible or invisible markings on the cop or in particular on the cop tube (the coil former)
  • the two sensors are combined in a guided past the workstations probe for contactless recording of signals, which is connected to a monitoring unit
  • the monitoring unit also receives quality data from a yarn inspector and a second identification sensor, both of which are arranged on a further processing machine for the yarn, for example a winding machine around the first and second Identification sensor received an assignment of quality data for each job before.
  • a "quality profile" can be created for each spinning station, which indicates how good the quality of the yarn spun on the respective spinning station is , better adjusted or repaired. For this it may be necessary to temporarily shut down the spinning station.
  • the inventive device thus serves to monitor a plurality of jobs of a ring spinning machine, where yarn is spun and wound on Kop sleeves.
  • the device has at least one Garnprüfer and a second identification sensor for the identification of Kop sleeves.
  • the yarn checker and the second identification sensor are arranged on a yarn processing machine.
  • a monitoring unit is connected to the yarn inspector and the second identification sensor for receiving data.
  • the device further includes a passable past the workstations probe for contactless recording of signals.
  • the probe has a motion sensor for monitoring the workstations and a first identification sensor for the identification of Kop sleeves at the work stations and is set up for the transmission of data to the monitoring unit.
  • the invention also includes a combination of a ring spinning machine with a further processing machine.
  • the ring spinning machine has a plurality of work stations where yarn is spun and wound up on coping sleeves.
  • the finishing machine continues to process the yarn.
  • At least one yarn checker and a second identification sensor for identifying cop tube are arranged on the further processing machine.
  • a monitoring unit is provided, which is connected to the reception of data with the Garnprüfer and the second identification sensor.
  • the combination also includes a passable past the workstations probe for contactless recording of signals.
  • the probe has a motion sensor for monitoring the workstations and a first identification sensor for the identification of Kop sleeves at the work stations and is set up for the transmission of data to the monitoring unit.
  • yarn is spun at the work stations and wound onto coping sleeves.
  • the yarn is subjected to a quality test and coping sleeves are identified.
  • Data is assigned to the quality inspection using the identification during further processing of the work site where the yarn was spun.
  • the Kop sleeves are identified at the workplaces. The identification during the spinning process is also used for the assignment.
  • the advantages achieved by the invention are to be seen in particular in the fact that the identification of the cops on the spinning machine is absolutely reliable, since this happens still on the spinning position during the spinning process. This saves a separate reading device for markings on the cop, which is normally arranged at the output of the spinning machine. Due to the arrangement of the first identification sensor on a probe, for. The identification of the individual cops takes place redundantly several times, ie in the case of several passes of the probe head, thereby precluding or correcting erroneous acquisition of the data on the cop if it occurs.
