    The thread-piecing device has a counter (3) which sums successive failed piecing operations of the device. When a predetermined number n of failed piecing attempts is reached, a faulty working of the thread-piecing device is presumed and its work is interrupted or servicing is performed. The counter (3) works in addition to a counter of known type which sums failed piecing attempts on the worked spinning or twisting station and which, when a predetermined number m is reached, causes the thread-piecing device to run further to the next station, since a fault on the respective station itself is to be presumed. The number n must accordingly always be selected larger than m. <IMAGE>

    (54) DEVICE FOR CONTROL BREAKING AND SPLITTING THREADS TO SPINNER AND TWISTING MACHINES
    t
    The invention relates to the textile industry and can be used in clamping and twisting machines to control breaks and splicing.
    A device is known for monitoring the threading j and straightening of the threads to the spinning and twisting machines, containing a block for tracking the presence of the thread, the output of which is connected to the cpmjasamaatM machinery mechanism, the number of splicing operations counter and signaling units (1
    The known device provides monitoring of the implementation of the lamination of the process of larascuation of the thread due to the fact that the sensor of the tracking unit probes the presence or absence of the thread. In the presence of a thread, it continues the dvzheii (HBaroiuero mechanism, in the absence of a thread, it provides a process for building up iichi.
    However, it is possible that, because of a clipping belt, for example, a driving belt, no roving, etc., the splicing mechanism does not work. In this case, the splicing process must be repeated. In a known device, the counter of the number of operations for splicing is calculated - 5
    The number of imaginary attempts at splicing on one spindle and after a set number of attempts the sensor moves to the next spindle, where the counter again counts the number of imaginary unsuccessful attempts. In this case, the sensor itself has a fault, which can only be noticed by service personnel.
    Thus, the known device does not provide control over the operability of the device itself, which reduces its reliability.
    The aim of the invention is to increase the reliability of the device.

    Claims (2)
    [1]
    The target is achieved by having a TBO device comparator and a meter reset unit, the input of which is connected to the second output of the tracking unit, and the output is electrically connected to the counter-extinguishing input, while the comparator input is connected to the output of the counter, the numerical input of which is connected to one of the outputs of the splicing mechanism maschiya, and the outputs of the comparator connects to the blocks of the machine and alarm system. 3 On f | g. 1 n {I1 introduced the structural scheme of the proposed device; in fig. 2 shows the connection scheme of the device with the spinning machine, the sensor of the tracking unit 1 controls the presence of the thread 2. If the thread 2 is cut off, a command is given to build up the thread in the qp iuHsa mechanism 3. After the splicing is completed, the sensor of the tracking unit 1 controls the thread thread availability

    2. If the thread. 2 is not interrupted, the reset unit 4 extinguishes the readout of the number of splicing operations S, which is connected to the output of the reset unit 4 and with the input of the compiler b. The counter of the number of spliced operations 5 on unsuccessful attempts can be canceled by a signal of a successful attempt. The comparator 6, which monitors the counter of the number of operative splices 5, introduces a certain number of permissible output values (High voltage. The output of the comparator 6 is connected to the stop and alarm blocks 7 and 8. The device operates as follows. successively probe the presence of the thread on the spindles 9. When the thread breaks, they are given a command to merge the thread. If the splicing mechanism 3 has made the allowable number of attempts to grow, for example three, then it moves to the next The spindle has a broken spindle. In the counter of the number of splicing operations, three unsuccessful attempts are stored. If the second spindle has the first, second and third attempts successful, then the counter 5, reached four, five or six, goes out. buildup on this spindle fails, then the cause of the failure of the splicing is not in the end of the thread, but in the device itself. Comparator 6 in this case gives the command to activate the stop unit 7 and the alarm unit 8. 2 Detecting the reason for the absence This is easy if the splicing mechanism stops on the second spindle. Since the counter 5 at the beginning of the last (third) building process on the second spindle shows the amount right, and it is still not clear whether this process is successful or not, it is preferable that the stop and alarm command was given after checking this last splice attempt. If this is not observed, then the splicing mechanism stops its work after the second unsuccessful attempt on the second spindle or after seven permissible unsuccessful attempts is moved to the next spindle. Claims An apparatus for monitoring breaks and splicing threads to spinning n torsion masks contains a block for tracking the presence of a thread, the output of which is connected to the masking mechanism, the number of splicing operations and signaling stop blocks, characterized in that Improving operation reliability, it has a comparator and a meter reset unit, the input of which is connected to the second output of the tracking unit, and the output is electrically connected to the counter-extinguishing input, while the comparator input is connected It is connected to the output of the counter, the numerical input of which is connected to one of the outputs of the maschina's splicing mechanism, and the outputs of the comparator are connected to the machine stop and alarm units.
