    An electronic weft or filling thread monitoring device on a gripper shuttle weaving machine provided with a rotatable color changing mechanism comprises a signal generator or weft thread travel sensor fixedly mounted in the area between the color changer and the point where the weft thread is transferred to the gripper shuttle or projectile. Only the one of the weft threads which is ready for transfer to the gripper shuttle is located in front of the signal generator without touching the same, and is lead in contact with the signal generator only when the projectile is driven into the weaving shed.

    The invention relates to the textile industry, and more specifically to devices for controlling the weft yarn on a shuttle loom with a color changing mechanism.
    A device for controlling a weft yarn on a shuttle loom with a color changing mechanism is known, comprising means for determining the breakage of yarns connected to the loom stopping unit m.
    The main disadvantage of the device is the complexity of the design.
    The purpose of the invention is to simplify the design.
    This goal is achieved due to the fact that, in a device containing means for detecting thread breaks, connected to a weaving machine stop unit, the means for detecting thread breaks is made in the form of a sensor controlling the integrity of the weft thread, the sensitive element of which is located at the place of the weft thread from the changer colors in the plane of the corner with the apex at the point where the weft yarn comes out of the color changing mechanism and the rays passing through the extreme positions of the hook clamping element.
    FIG. 1 shows the color change mechanism; FIG. 2 is a schematic representation of the direction of movement of the weft yarn and the location relative to the yarns of the weft integrity monitoring sensor; in fig. 3 design of a triboelectric sensor for checking the integrity of the weft thread; in fig. 4 is a section A-A in FIG. 3, side view; in fig. 5 is the same top view of FIG. 6 - construction of a piezoelectric sensor for monitoring the integrity of the weft thread; in fig. 7 is a section BB in FIG. 6, side view in FIG. 8 is the same, a view of j in FIG. 9 - location of the sensor control weft yarn relative to the mechanism for changing color, side view; in fig. 10 - location of the sensor monitoring the integrity of the weft thread relative to the Shuttle (microloop); in fig. 11 - the location of the weft yarn before and after it is rolled.
    The color change mechanism 1 (Fig. 1) is mounted for rotation about an axis 2 mounted on sector 3. The color change mechanism surface 4 has grooves 5 in which are mounted links 6 with lugs
    7 day threads. Position 8 denotes the microplotter (microcell)
    5 with clamping element 9.
    The mechanism 1 has tubes 10 (FIG. 2) in which weft yarns 11 are located. Tubes 10 are mechanically connected to a disk 12 having openings 13 to pass weft threads. Tubes 10 are also mechanically connected to sector 3 by means of springs 14.
    Sector 3 has holes 15 in the number of tubes to. T6 position
    15 depicts a sensor monitoring the integrity of the weft thread, installed at the place of withdrawal of the weft thread from the color change mechanism.
    Triboelectric sensor16
    0 is mounted on a bracket 17 and comprises a housing 18, guides 19, a sensing element 20, insulated from the housing 18 by a gasket 21. A connection of the sensing element 20
    5 with stop unit (not shown)
    the weaving machine is carried out via wire 22 and coaxial cable 23.
    The piezoelectric sensor 16 co-holds the body 24 with two guides 25, the piezoelectric element 26 with the sensitive element 27 interacting with the thread 11. The piezoelectric element 26 is connected to the body 24 through a damping material 28.
    The six-mechanism of 1 color change is fixed on the bed 29 of the weaver, of the machine by means of the bracket 30. On the bracket 30 is mounted
    A Q amplifier 31 connected to sensor 16 via cable 23.
    Position 32 shows the movement path of the weft yarn. The positions 33 and 34 show the rays passing through the 5 extreme positions of the clamping element of the microslide.
    FIG. Figure 11 shows schematically, on an enlarged scale, the trajectory 32 of the movement of the weft yarn, the extreme positions of the clamping element 9 of the microarray 8. The position 35 shows the starting point for controlling the weft yarn 1 1.
    The device works as follows.
    The color changing mechanism 1 is set to a predetermined position. The hole 15 with weft thread
    It appears opposite the microdrop 8. The microscopic clamp 8 element 9 seizes the weft thread 11 and begins to move to the right. At the beginning of the movement of the microranule 8, the weft thread 11 does not touch the sensing element 20 of the sensor 16, and no signal is given for a broken weft. If the same thread does not touch the sensitive element 20 at the control point 35, i.e. then when the point

    The weft yarn, which is located before opening in hole 15, will be located at control point 35, the device will operate and stop the machine. Thus, the oTcytcTBHe weft yarn at point 35 indicates that the yarn is dead.
    The economic effect of using the proposed device is determined by the simplicity of its design.
