Definitions

  • the invention relates to a method for operating a Cross-wound textile machine according to the preamble of claim 1 or a device for a such a textile machine according to the preamble of claim 6.
  • Such textile machines for example automatic winder, are for example by DE 195 12 891 A1 or DE 195 20 133 A1 known.
  • the package changer transfers finished Cross-wound bobbins from the winding device of a job to one machine-long, arranged behind the winding devices Cross-coil transport device and then changes a new temporary storage location Empty tube into the winding device.
  • the cross reel changer points accordingly DE 195 12 891 A1 a sensor device in the form of a Light button on.
  • Cross-coil transport device before initiating the Cross-wound process scanned. That is, the package change process is only then started when determined using the sensor device was that the relevant storage space on the package transport device free is.
  • a comparable sensor device is in connection with an open-end spinning machine also in DE 37 31 125 A1 described. This also applies to this known textile machine mobile control unit a sensor device for scanning a package transport device.
  • the Sensor device is either mechanical Push button or as a photoelectric sensor element educated.
  • photoelectric Sensor devices can be avoided because such Work sensor devices without contact; optical
  • facilities are known to be very sensitive against pollution.
  • photoelectric sensor devices a regular, careful maintenance, otherwise the malfunction of the Sensor devices can hardly be prevented.
  • Another disadvantage of photoelectric light sensors is that that such sensor devices strongly from the coloring of the object to be scanned are dependent. That is, bright objects are detected much more reliably than dark objects. Frosted black objects are almost impossible to detect.
  • Non-contact sensor devices are from the general mechanical engineering also in the form of so-called Ultrasonic proximity switch known. Such ultrasonic proximity switches can be used in objects Record distances between approx. 6 and 600 cm. Ultrasonic proximity switches are commercially available Components whose function, for example in a prospectus Siemens company (Siemens NS 3, 1991), is explained.
  • DE 39 32 665 A1 relates to a person and Collision protection device for an automatically working Control unit of a ring spinning machine.
  • the control unit has one at each electronic control unit connected electro-acoustic Transducer that delivers a two-part transmit sound signal.
  • a sound measurement signal is emitted in the direction of travel, while a sound reference signal on a reference reflector, for example the hall floor.
  • the electronic control unit delivers a detection signal or directs a reversal of the direction of travel Control unit on if on before the reference runtime expires Sound signal is received because such a sound signal indicates an obstacle in the travel path of the control unit. There remains a sound signal until the expiry of the Reference sound signal off, the control unit signals one Error and shuts down the control unit.

  • Preferred embodiments of the device are in the Subclaims 7 to 11 described.
  • the first step is to work with a reference sound signal, that is to say with a sound signal which is sent over a measuring section whose exact length is known. Since both the length of this measuring section and the running time of a sound signal are known via this measuring path under certain climatic conditions, any deviation in the running time of the reference sound signal immediately allows conclusions to be drawn about the prevailing climatic conditions, which are taken into account as a correction value when evaluating the running time of a subsequent measuring sound signal will. Based on the correspondingly corrected sample value, it is then possible to make a reliable statement about the respective loading condition of the relevant storage area of the cross-wound bobbin transport device.
  • the maximum and the minimum permissible distances between the ultrasonic sensor and the transport device are first determined and fed into the control device of the package changer.
  • This so-called large tolerance range takes into account all height deviations of the transport device that can occur due to machine tolerances as well as all measurement errors due to possible climatic conditions.
  • the control device then becomes quasi calibrated ", that is to say, the transport device is scanned by the ultrasonic sensor. All the scanned values in the range of the maximum permissible distance are stored in the stone device, which permanently forms an average value therefrom. This average value corresponds to the average distance of the cross-coil removal belt from the ultrasonic sensor of the cross-coil changer .
  • a so-called tolerance band is placed around this mean value, the width of which only takes into account height differences due to permissible machine tolerances.
  • the device according to the invention which is described in claim 6, has the particular advantage that important parts of the monitoring device, preferably the control device, are already present on the cross-wound bobbin changer and can be used without major design effort. It is only necessary to set the existing control device of the interchangeable unit in software to the ultrasonic sensor. The computing capacity of the control device is in any case sufficient to be able to take on this additional task without any problems.
  • the Ultrasonic sensor designed so that it is used to 'calibrate' the Ultrasonic sensor device first a reference sound signal emits that in the control device into a correction value is implemented. That is, based on the term of the Reference sound signal is in the control device on the prevailing climatic conditions closed.
  • This correction value is then used during normal Operation of the package changer when evaluating the Running time of a measurement sound signal is taken into account (claim 7).
  • a reference path is formed in the scanning area of the ultrasonic sensor.
  • a sound-reflecting component which is arranged, for example, on a handling device of the cross-wound bobbin changer and whose distance from the ultrasonic sensor is predetermined by the design and is therefore precisely known, is swiveled into the area of the sound cone of the ultrasonic sensor or traverses the scanning area as a result of the process.
