Definitions

  • the present invention relates to a device for monitoring a warp thread, in particular a leno warp thread according to the preamble of claim 1.
  • the invention further relates to weaving machines with a device according to the invention.
  • one or more leno edges can be created with warp threads by means of a leno weave to create a solidified fabric edge.
  • These warp threads also called leno warp threads, are usually guided and monitored separately from the other warp threads. It is known to monitor breakage of a warp thread with a warp thread monitor by detecting whether a warp thread is present or not.
  • the object of the present invention is to develop a device for monitoring a warp thread, in particular a leno warp thread, in such a way that it has improved properties with regard to the monitoring of the warp thread.
  • the advantages of the invention can be seen in the fact that the withdrawal movement or the withdrawal speed of the warp threads can be detected approximately or precisely with an electronic sensor, in particular it can be determined whether the withdrawal movement or the withdrawal speed has a very low or a relatively high value. If the value is very low, especially if the warp threads are at a standstill during the weaving process, it can be concluded that the warp thread has broken. If the take-up speed value is above a predefinable threshold value, it can be concluded that the warp thread has been torn away in an undesirable manner, so that an error signal is generated in order to interrupt the weaving process.
  • the electronic signals from the sensors are fed to a signal processing device, the one can include digital or analog evaluation electronics, for example also a microprocessor, in order to compare a measured value with a predeterminable target value and, when it is exceeded or undershot, to generate an error signal which is forwarded to a higher-level unit, for example to shut down a weaving machine.
  • digital or analog evaluation electronics for example also a microprocessor
  • the rotor 1 shows the device according to the invention in combination with a row shed weaving machine with a weaving rotor 1 rotating in the direction of rotation 1a.
  • the rotor 1 has guide elements 2a, 2b, 2c, into which the warp threads 3a, 3b are inserted by means of an insertion device 9a, 9b, that the guide elements 2a, 2b, 2c form an open shed into which the weft threads 10a, 10b can be inserted.
  • the insertion device 9a, 9b controls the insertion of the warp threads 3a, 3b in such a way that an edge 3d forms at the edge of the fabric 11, which comprises weft threads 10c, 10d.
  • an arrangement 5 for detecting the movement of the warp threads 3a, 3b comprises for each warp thread 3a, 3b a thread roll 5a, 5b, on which the warp thread 3a, 3b rests, and through the warp thread 3a moving in the direction of the fabric 11 , 3b experiences a rotation in the direction of rotation 5f.
  • the two Thread rolls 5a, 5b are mounted on a common axis 5e via a coupling part, for example a one-way clutch or a slip clutch 5c, 5d.
  • the axis 5e is connected to an electronic sensor 6, which detects the rotation of the axis 5e and forwards the electronic signal via a signal line 7a to a signal processing device 7.
  • Eyelets 8 serve to guide the warp threads 3a, 3b in order to guide them on the thread roll 5a, 5b and to ensure an approximately constant wrap angle.
  • the thread rolls 5a, 5b can, as shown, be wrapped around only with a fraction of a full circle, or can be wrapped around several times in order to thereby increase the friction between warp thread 3a, 3b and thread roll 5a, 5b.
  • the device according to FIG. 1 has the advantage that a plurality of warp threads can be monitored simultaneously with a single sensor. Not shown in FIG. 1 are braking devices which may be necessary in order to bring about a braking force on the warp threads 3a, 3b, for example between the thread supply 4a, 4b and the thread roll 5a, 5b.
  • the angular velocity of the weaving rotor 1 in the direction of rotation 1a is significantly higher during weaving than the speed of the movement of the warp thread 3a, 3b in the direction of the fabric 11. If a warp thread 3a, 3b is inserted into a guide element 2a, 2b, 2c, an error occurs, such as this is shown for example on the basis of the warp thread 3c, the warp thread 3c may be entrained by the guide element 2b and thereby accelerated to a speed which is determined by the angular speed of the weaving rotor 1. If such an acceleration occurs in one or both of the twist threads 3a, 3b, the rotational speed of the common axis 5e accelerates, so that the occurrence of such an error can be detected by the sensor 6.
  • the signal processing device 7 is a threshold value 12 can be specified, at which the signal processing device 7 exceeds or falls below an error signal 13, for example to stop the weaving rotor 1.
  • the arrangement 5 also allows a thread break to be detected. If, during weaving, the angular velocity falls below a predefinable target value, for example when a thread reel 5a, 5b is at a standstill, it can be concluded that a thread breakage of the warp thread 3a, 3b has occurred, or that the thread supply 4a, 4b has been used up.
  • the arrangement 16 consists of two sensors 6a, 6b, which are spaced apart in the running direction of the warp thread 3a and monitor the warp thread 3a.
  • the electronic signals from the sensors 6a, 6b are fed via signal lines 7a, 7b to a signal processing device 7 which determines the speed of the warp thread 3a by means of a correlation of the measured values.
  • the part of the warp thread 3a lying between the two sensors 6a, 6b is guided through eyelets 8 on a line which is as straight as possible, a thread brake 14 acting on the warp thread 3a keeping the warp thread 3a stretched.
  • the warp thread 3a is deflected via a thread roll 5a and fed to a weaving machine.
  • the sensors 6a, 6b are based, for example, on an optical or capacitive measuring principle.
  • Another arrangement 16 for determining the speed of the warp thread 3b comprises three eyelets 8, 8a in order to deflect the warp thread 3b in a U-shape, the eyelet 8a designed as holding means being elastic Element, for example a spring 15, is connected to a solid body.
  • the eyelet 8a experiences a deflection which can be detected by a sensor 6c, for example an optical sensor or a displacement sensor, and is fed to a signal processing device 7 via a signal line 7c.
  • the arrangement 16 also allows a jerky deflection of the warp thread 3b to be detected.
  • FIG. 3 shows an example of a leno weave, consisting of three warp threads 3a, 3b, 3c, which can be produced with a row shed weaving machine according to FIG. 1 if three warp threads 3a, 3b, 3c controlled by insertion devices 9a, 9b are used for this purpose.
  • the number of warp threads required depends on the type of fabric edge or auxiliary edge to be created.
  • the warp threads 3a, 3b, 3c are expressed in more differentiated terms than leno warp threads 3a, 3c and as a standing thread 3b.
