Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a thread breakage monitoring device for a spinning machine, a yarn twisting machine, a thread cutting machine, etc. (hereinafter referred to as a spinning machine, etc. in the present application). A thread breakage detection head is attached that can send a signal according to the thread breakage detection head, and the signals from these stationary thread νj deviation detection heads are sent to the discrimination device at the end of the machine for each spindle to detect thread breakage for each spindle. This system is used in a yarn breakage monitoring device such as a spinning machine, which is capable of monitoring yarn breakage.

In spinning machines, etc., if yarn breakage occurs and the condition of yarn breakage is allowed to dissipate, not only will the operational efficiency decrease and raw materials be wasted, but also the winding of yarn on the draft roller + 1 mist or newer filling will be difficult. It is known that it mainly causes damage to the machine. For this reason, in Kizai, workers regularly walk between the spinning spindles, etc., and if they find a thread breakage, they repair it on the spot. However, manually detecting thread breakage by a worker not only increases the worker's fatigue level and requires a large number of workers, but also leads to failure to detect thread breakage. there were. Therefore, in order to solve the above problem, we have developed a device in which thread breakage detection heads are attached to each pot, and signals from these thread breakage detection heads are sent to a discrimination device at the end of the spindle. Several have been proposed. However, these conventional devices monitor whether there is any thread breakage for each row of spindles or for each pot group, and are unable to monitor all thread breakages for each pot. Also, in order to monitor yarn breakage for each pot based on the conventional device, it may be possible to wire each yarn breakage detection head to the discrimination device individually.As is well known, spinning machines have a large number of spindles. Therefore, the number of wires to be distributed and the length of the wires became extremely large, resulting in high costs, and the wiring space became large, making it impractical.

Therefore, the present invention aims to solve one of the problems in the prior art described above, and it is possible to reliably and stably detect thread breakage at each spindle by attaching a thread breakage detection head to each joint. Even with the Jochi-type thread breakage monitoring device, it is possible to monitor thread breakage in each pot.
) It is an object of the present invention to provide a practical yarn breakage monitoring device for spinning machines, etc., which allows coarsening with an extremely small number of wires and a very small wire length.

When a clock pulse signal is applied, the high or low level signal of the D terminal is stored and the Q terminal outputs that signal, and even if the terminal changes thereafter, the next clock pulse signal or 0' is applied to the terminal. This state will be maintained until then. Therefore, the data latch signal is applied to the entry 1 surface power terminal 15b of the AND gate 11 path 15 i6
9 If there is a signal from the thread breakage detection head 10 within the time (
If the thread is not broken), the Q terminal of the D-type FII'16 is set to high level, and if there is no signal from the thread breakage detection head 10 (if the thread is broken), the Q terminal is set to low level. As a result, the thread breakage state of each weight 2 at that time is stored in the D-shaped FP 16 corresponding to that weight 2. The power terminal 19a and the ground terminal 191) of the yarn breakage detection head 10 and the memory circuit 11 are connected to the power line 118& and the ground line 18b, respectively, via the connector 17.

The 16 Ox terminals are connected to a shift signal m1aa via a connector 17, thereby forming a shift register 20 as a whole. The shift register 20 of this ID has various shapes when a shift signal consisting of a four-pulse signal is applied to the shift signal line 18d.

Each time a shift signal is applied, the signal (high level signal or low level signal) stored in the D-type FPi 6 stored in the D-type FPi 6 on the output side (right side in the figure) is shifted to the final output terminal (the right side in the figure). The signals stored in each type II'F 16 are sequentially outputted from the Q terminal of the n-type ppl 6 (the rightmost one) each time a shift signal is input. The Q terminal of the D-type IPF 16 at the final output end is connected to a discriminating device to be described later. Above power supply @ 18a, ground wire 1

Therefore, each p'F 16 can be cleared by applying a shift signal to the shift signal line 18cl.

Next, at the out-end end of the frame 1 of the spinning machine, a predetermined operation is performed to transmit a shift signal after transmitting a shift signal to each of the memory circuits 11 for a certain period of time t (for example, 0.06 seconds). The scanning device 22 repeatedly performs the scanning at intervals of time T (for example, 1 second), and the presence or absence of a storage signal transmitted from the Q terminal of the storage circuit 11 at the final output end in conjunction with the shift signal of this scanning device 22 is determined. A discriminating device @ 23 that can be used to determine the size of the cylinder, and a processing device 24 that processes the cylinder shaft and the like based on signals are attached to the discriminating device 230. The scanning device 22 is operated when the machine operation switch 25h is turned on as shown in Fig. 10.11.

It is possible to determine the presence or absence of

/l1113 Next, the processing device 24 can notify the worker of the occurrence of thread breakage in the weight 2 based on the thread breakage signal from the discrimination device 26 by lighting a lamp, sounding a buzzer, etc. - a counter 26 capable of counting and displaying the total number of thread breakages for every two rows of weights or for each machine based on the thread breakage signal; and a thread breakage signal from the discrimination device 23. The control device 27 is configured to perform data processing related to thread breakage based on a shift signal from the scanning device 22. The spinning machine 25 needs to be always provided in the spinning machine considering the n-th machine, and is specially attached to the end of the machine frame. This warning device f1125 is designed to issue an alarm when thread breakage occurs in a preset number of weights 2. It is preferable that the above-mentioned counter 26 is always provided in the spinning machine for production control and machine management, and this counter 26 is also specially attached to the end of the machine frame.

The control device 27 uses a microcomputer to count the number of thread breaks for each spindle 2, the total number of thread breaks at the start of spinning, and the number of thread breaks for each doffing and doffing.14 Arguments , (2) Calculation of the average value of thread breakage duration time, (2) Calculation of production loss caused by thread breakage, etc., as well as storage and display of the results of these calculations.

Considering its function, it is sufficient to temporarily provide this control device 27 in the spinning machine, and as shown in FIG. ing. Further, this control device 27 is connected to the discrimination device 23 via a connector 28. The control equipment 12
The control device 27 is attached to the machine 1 by placing it on the mounting surface 1a of the machine 1. This may be done by locating it nearby &C. The purpose of the control device 27 is to check the state of yarn breakage related to the operating state of the spinning machine, fineness maintenance state, various spinning conditions, etc., and among the above-mentioned calculations The other calculations ① to ② can be omitted, and it is also possible to perform calculations other than those described above by changing the program.

Bird 15 Next, the operation of monitoring yarn breakage in a spinning machine using the yarn breakage monitoring device configured as described above will be described.

Generally, a large number of spinning machines are installed and operated in each factory, and when monitoring thread breakage on spinning machines, it is important to monitor each spinning machine in the factory for thread breakage in order to perform production management and machine management. It is preferable. In this case, in the thread breakage monitoring device of this embodiment, the processing device 24 is composed of a warning device N25, a counter 26, and a control device 27, and an alarm device 25, which must be always provided in the spinning machine, is provided. A counter 26, which is preferably provided at all times, is attached exclusively to the machine frame 1, and a control device 27, which is sufficient to be temporarily provided in the spinning machine, is constructed in a portable manner and can be freely removed from the machine frame 1. Therefore, the spinning machines in the above factory were divided into groups of many machines, and only one spinning machine in each group was equipped with the yarn breakage monitoring device of the embodiment of the present application, and the other spinning machines were is equipped with the thread breakage monitoring device of the embodiment of the present application with the control device 27 removed, and
The control device 27 according to the embodiment of the present application can be shared at different times for monitoring thread breakage in other spinning machines within a group. Therefore, the control device 27, which costs a relatively high price, is provided in only one of the many spinning machines in each group, and the hem/shaft device 25 and the counter, which can be prepared at a relatively low cost, are installed in the other many spinning machines. 26 as a processing device, the yarn breakage monitoring device according to the embodiment of the present application can be installed on all spinning machines at different times, thereby reducing the cost required for monitoring yarn breakage on each spinning machine. can be effectively reduced. If you wish to use the control device @27 to process yarn breakage data for another spinning machine, pull out the plug 28a of the connector 28 from the socket 28b and connect the control device 27 to the desired 10-piece spinning machine 1a. Then, the socket of this machine 1) 28
This can be done by inserting the plug 28a into b.

Next, when the spinning machine operation switch 25a of the spinning machine 1 is turned ON to start one spinning operation, each &M2 starts winding the yarn onto the bobbin, and this yarn turns the traveler 4 on the ring 5. At the same time, the thread breakage monitoring device enters the thread breakage monitoring state, and starts thread breakage monitoring at each weight 2 at step 617 as follows. First, at each weight 2 position, if the thread at that weight 2 is not broken, this thread will rotate the traveler 4 on the ring 5, and this traveler
4 cuts the magnetic field of the detector 12 of the thread breakage detection head 10 every time it turns. This VC generates an electromagnetic induction current in the coil 12Q of the detector 12 as shown in FIG. 14A, and a signal (a) based on this current is output from the detector 12.

The signal (a) from the detector 12 is amplified and waveform-shaped by the amplifier 13 and transformed into a pulse signal (b) as shown in FIG. 14A. Furthermore, if the thread at each weight 2 breaks at the second position IW, the traveler 4 stops rotating, so a pulse signal is output from the detector 12 and amplifier 13 as shown in FIG. 14B. Never. On the other hand, when the machine operation switch 23a is turned on, the scanning device 22 shifts to the shift signal line 18 as shown in FIG.
A shift signal (to) is transmitted to the D-type FFI 6 of the memory circuit 11 corresponding to each weight 2 to be reset to a low level to perform a clearing operation, and after a predetermined time T, a data latch signal j is sent to the line 180. The first data latch signal (c) is transmitted for a certain period of time. By transmitting this data latch signal (c), the AND gate circuit 15 of each memory circuit M11 determines that if the pulse signal (b) is input from the amplifier 13 while the data latch signal is being input, that is, if there is no thread breakage, the AND gate circuit 15 of each memory circuit M11 14 Output thread signal ) as shown in Figure A, and output thread signal ) as shown in Figure A.
Di? input to PS terminal of F16? If the Q terminal of Fi (5) is set and held at a high level state, and the pulse signal (B) is not input from the amplifier 13 during the data latch signal input, that is, if the thread is broken, the signal shown in Fig. 14B is shown. As shown, the AND/KATE circuit 15 does not stop outputting the yarn signal (%) and the Q terminal of the DyFF 16 is held at a low level. Therefore, by transmitting the data latch signal (c), the yarn breakage state at each weight 2 at the time of transmission is stored as a low level state in the rectangular FF 16 corresponding to each weight 2. The presence or absence of yarn breakage at each weight 2 is detected in the storage space 9 formed within the separator 8, so that the yarn breakage detection head 10 and memory circuit 11 are not exposed to the outside during machine operation. A 19 It is possible to prevent functional deterioration due to repeated wearing of wind cotton due to force, and it is possible to reliably detect yarn breakage over a long period of time. When the transmission of the data latch signal (c) is completed 2, the scanning device 22 transmits a shift signal (c) to the shift signal line 1aa. By transmitting this shift signal (to), each type of FF 16 that constitutes the shift register 20 is
A shift signal (to) is simultaneously inputted to the K terminal, whereby the stored signal of each type FFi 6 is shifted by 1@ to the output side for each shift signal (to). Therefore, the D type of the final output end? From the Q terminal of F16, first the shift signal (to)
When the input is 0 times, the memory signal at the weight 2 at the final output end is output, and when the shift signal (to) is input once, the memory signal at the second weight 2 from the final output end is output. is,
When the shift signal (to) is inputted N-i times, the memory signal for the Nth weight 2 from the final output end side is output, and these memory signals are discriminated and input to the device 23 to be processed for each weight 2. The presence or absence of thread breakage is determined. This discriminating device 23 outputs a discriminating signal depending on whether there is a thread breakage or not, depending on whether there is a thread breakage or not, and whether the discriminating device 23 receives the above-mentioned memory signal. is input to the moving shaft device 25 and counter 26 of the processing device 24.The cylinder shaft device 25 receives the thread breakage signal from the discriminating device if+: 25 a preset number of times (for example, once or twice). Then, a warning is issued by lighting a lamp or sounding a buzzer.Therefore, the worker follows the warning from the death alarm device 25 and goes to the position of the spindle 2 of the spinning machine and splices the yarn with the thread cutting weight 2. The counter 26 counts and displays the number of thread breakage signals inputted from the determining device 23.

The above operation is carried out in all spinning machines regardless of the presence or absence of the control device ff127. Further, in a yarn breakage monitoring device for a spinning machine to which a control device 27 is attached, a discrimination signal from the discrimination device 26 is input to the control device M27. In this control device 27, the discrimination signals that are inputted sequentially for each weight 2 from the discrimination device M"2""r are stored for each weight. After being transmitted the same number of times as
The Q terminal of iIPFIS is cleared to low level. Thereafter, after a predetermined time T has elapsed, the scanning device 22 transmits a second data latch signal (c), repeats the detection of thread breakage at each weight 2 and the reading of the detected signal, and thereafter switches the above operation to the full tube switch. This process is repeated until 23b is turned ON. In this case, a signal indicating the number of data latch signals is also input to the control device 27, and by comparing it with a previously stored signal, it becomes possible to calculate the thread breakage duration and the like. After that, when the full tube switch 23b is turned on, the data latch signal (c) and the shift signal (f)
Transmission is stopped and doffing of the full bobbin is performed. At this point, the counter 26 displays the total number of thread breakages for all spindles 2, and the control device 27 stores data regarding thread breakages for each spindle 2 during one bobbin inspection, and The results of calculations input in the BUDARAM are displayed as needed or all the time. The results of these calculations are displayed using a display device, a printer, etc. The calculation in the control device 27 can be performed by counting the thread breakage signals from the discriminating device 23 in each input order, and the calculation [Yes] is performed when the machine is started, that is, when the first data latch signal is transmitted. This can be done by summing the number of thread breaks, and the calculation can be performed by summing the number of thread breaks after a predetermined period of time has elapsed since the start of the machine. This can be done by averaging the time from input to the next input of the thread presence signal (which can be determined by the number of times the data latch signal is sent), and can be easily performed based on the calculation of the thread breakage duration time. be able to. After replacing the full bobbin above, switch the machine operation switch 2 again.
3a is turned on to start winding the thread onto the next bobbin. In this case, the count value of the counter 26 is reset to zero and then starts counting to one.

K is connected to one output terminal 3oaKSD type IPv16Eg) of the polarity discrimination circuit 30, and the OK terminal is connected to the other output terminal 30b of the polarity discrimination circuit 30, thereby forming a memory circuit 11K. The input terminal of the circuit wJ30 is connected to the scanning signal line 18clDK. If a signal of negative polarity is input to the input terminal of the polarity determination circuit 30, a signal is output to the output terminal 60a connected to the AND gate circuit 15, and if a signal of positive polarity is input to the input terminal, the signal is output to the output terminal 60a connected to the AND gate circuit 15. A signal is output to the output terminal 60b connected to the terminal. The scanning device 22 receives scanning signals &! After transmitting a negative polarity data latch signal (c) to 180K, a positive polarity shift signal (c) is transmitted to this scanning signal line 18cl. Therefore, in the case of this embodiment, each memory circuit 111C and the discriminating device 23 can be wired with one less connection wire than in the above embodiment. This example and the next example are the same as those in the above example, or are molded with the same numerals as the parts corresponding to the parts considered to be equivalent 41i1 precepts, with the letters E and 1 added respectively.

In the above embodiment, the thread breakage detection head and the memory circuit are housed in the storage space of the separator, but these may be attached outside the separator or provided in the lappet section. The detection head is not limited to electromagnetic type books, but includes a photoelectric type that uses a phototube to detect the presence or absence of thread, a vibrating type that detects the presence or absence of thread by vibration of a thread guide, etc. It may also be an audio type that uses sound to detect the presence or absence of threads.

As described above, in the present invention, when a data latch signal is sent from the scanning device at the end of the machine to the storage circuit for each line, each storage circuit stores the signal from each thread breakage detection head, and then the shift i Since the determination signal from a separate circuit that transmits the signal is input to the processing device, it is possible to monitor each line at the end of the machine for yarn breakage at each spindle during spinning operation. It is possible to speed up the yarn splicing work by notifying the operator of the occurrence of yarn breakage, and it is also possible to understand the characteristics of each weight. Furthermore, even if the thread breakage at each spindle is monitored on the line side as described above, the signal from each thread breakage detection head is sent serially to the discrimination device by the shift register. As a result, it is possible to monitor the occurrence of thread breakage for each thread breakage, which reduces the total number and length of wires between each thread breakage detection head and the discrimination device, and reduces the equipment installation. It is possible to reduce costs. Further, as mentioned above, a yarn breakage detection head and all 101 memory paths are attached to each yarn, and these memory times are 1. Since the shift register is constructed by connecting the two wires in the same way as the scales, it is possible to make the storage circuit compatible with the thread breakage detection head attached to each line.
