[Problems to be solved by the device]

 By the way, since a spinning machine, a twisting machine, and the like each have several hundred bobbins, a warning display means in the above monitoring device indicates to the operator that the number of yarn breaks has exceeded the limit value. However, the worker must find out the bobbin with the yarn breakage from the hundreds of bobbins prior to the yarn splicing work, and since this work is extremely troublesome and time consuming, the productivity of the spinning machine etc. Does not contribute much to improvement. On the other hand, in order to increase the efficiency of the work to find the bobbin with a thread breakage, the bobbin is divided into a predetermined number of blocks to form a block, and the thread breakage sensor outputs the signal based on the output signal of the thread breakage sensor. A yarn breakage monitoring device is also put to practical use, in which the block to which the bobbin where the occurrence occurs occurs is indicated by a lamp. However, even with the monitoring device having such a configuration, it is necessary to find a bobbin that has a thread breakage from dozens of bobbins in the block, and particularly, use a very fine thread or a thread dyed in black or grey. In this case, it is not easy to identify the thread breakage with the naked eye, and improvement in work efficiency cannot be expected so much. The present invention has been made in view of the above problems, and an object of the present invention is to provide a yarn breakage monitoring device capable of increasing the efficiency of yarn splicing work and improving productivity.

There is. Further, a separator 16 is arranged between the adjacent bobbins 13 in order to prevent the cut filaments 15 from being caught in the adjacent bobbins 13.

As shown in FIG. 3, each electromagnetic sensor S includes a housing 17 and an L-shaped bracket 18, and the housing 17 has a coil wound core and a permanent magnet built therein. A light emitting diode D is integrally provided on the upper portion of the housing 17. Two long holes 18a are formed on one side of the L-shaped bracket 18, and an adhesive tape 19 is attached to the other side. The housing 17 is fastened to the L-shaped bracket 18 by passing the screw 20 through the elongated hole 18a. Each electromagnetic sensor S is arranged close to the ring 14 so as to form a magnetic circuit between the built-in permanent magnet, the core, and the traveler 14 traveling along the ring 11 along with the winding of the filament. Then, it is fixed to the ring rail 12 with an adhesive tape 19, and is connected via a lead wire 22 to a track rail TR mounted along the ring rail 12 to a frame 21 to which the separator 16 is fixed. A block display lamp BL is attached to the frame 21.

The track rails TR1 to TRn and the block display lamps BL1 to BLn are provided for each block formed by partitioning a large number of adjacent bobbins 13 into a predetermined number. On these track rails TR1 to TRn, amplifier circuits A1 to Am for amplifying the output signals of the sensors S1 to Sm and waveform shaping circuits B1 to Bm for shaping the output waveforms of the amplifier circuits A1 to Am for the respective sensors S1 to Sm. , A reference circuit for comparing the output voltage of the waveform shaping circuits B1 to Bm with a preset reference voltage, and a thread breakage signal forming means for outputting a thread breakage signal and switching circuits F1 to Fm.

When a thread breakage occurs in the bobbin 13, the traveler 14 running along the ring 11 stops, and the electromagnetic sensor S1 until then. The electromagnetic induction current generated in Sm disappears. As a result, the yarn break signal is output from the yarn break signal forming means, so that the light emitting diodes D1 to Dm integrated with the sensors S1 to Sm detecting the yarn break are turned on, and at the same time attached to the block to which the sensors S1 to Sm belong. The block display lamps BL1 to BLn are turned on. On the other hand, the thread breakage signal is transmitted to the control box CB, integrated here, and displayed on the display portion DP1. When the integrated value C of the thread breakage signal exceeds the preset limit value L, the warning lamp WL is turned on. Therefore, the worker goes to the block where the block display lamp BL is lit, finds the bobbin 13 in which the yarn breakage has occurred by using the light emitting diodes D1 to Dm that are lit in the block as a mark, and performs the yarn splicing work. .. As described above, in the present embodiment, the warning lamp WL indicates that the number of yarn breakages of the winding device 10 has exceeded the limit value L, and the block display lamps BL1 to BLn indicate that the bobbin 13 is broken. When the number of thread breaks exceeds the limit value L, the blocks to which the thread breaks occur are displayed by displaying the blocks to which the thread belongs and the individual light emitting diodes D1 to Dm provided integrally with the electromagnetic sensors S1 to Sm to display the individual bobbins 13 in which the thread breaks. By using the block display lamps BL1 to BLn and the light emitting diodes D1 to Dm as a mark, the operator can find the bobbin 13 in which the thread breakage occurs without hesitation. Therefore, the time required for the yarn splicing work can be reduced, and the productivity is greatly improved. Further, since the light emitting diodes D1 to Dm and the electromagnetic sensors S1 to Sm are integrated, they can be installed even in a limited space and the installation work is easy. Furthermore, since it is possible to partition a large number of bobbins into blocks simply by attaching the respective track rails TR1 to TRn, it is extremely easy to apply to existing equipment. Further, since the elongated hole 18a is provided in the bracket 18 for mounting the electromagnetic sensor, the mounting position and angle of the sensor S with respect to the ring 11 can be finely adjusted. Therefore, the sensitivity of the electromagnetic sensor S can be kept good. In this embodiment, the track rail was attached to the frame and connected to the electromagnetic sensor with the lead wire. However, if the sensor is attached to the track rail and the track rail is attached to the ring rail, the track rail is further attached. Work becomes easier. In addition to the warning lamp, a buzzer can be used as the warning display means.
