[Industrial Application Field] The present invention provides means for monitoring the running of yarn and winding condition in a yarn doubling machine, detecting yarn defects such as yarn breakage and thick yarn, and further winding the yarn to a certain length. The present invention relates to a winding yarn monitoring device comprising: [Prior Art] In a spinning machine that combines and winds up multiple single yarns, one of the single yarns breaks and becomes a defective yarn that is wound up as is, which naturally leads to the generation of defective yarns and This leads to a decrease in production efficiency due to thread breakage, etc. For this reason, conventionally, a mechanical tension sensor was placed corresponding to each single yarn in the doubling yarn.
A means for stopping the winding of the doubling machine using the lever action, or an electronic detector such as optical or electrostatic is arranged corresponding to each single yarn to detect yarn breakage and stop the machine. There were ways to send out signals. In addition, yarn defects such as neps, slabs, and thick yarns that cause defective yarns are detected and removed by a so-called yan clearer in the single yarn winding machine in the previous process, but the yarn defects during the winding process are The defective yarn portions, such as poor tying and adhesion of thread waste, remain as defective yarns without being removed. The purpose could be achieved if a yan clearer was similarly placed in the doubling machine for each single yarn in order to detect and remove it, but this would be expensive and the arrangement of the detector would be complicated. Become. On the other hand, it is preferable for the doubled yarn to be wound to a constant length for later processes such as twisting and diameter adjustment, and for this reason, the yarn doubling machine is equipped with an electronic constant length winding device that equalizes the package of each yarn. Now equipped. [Problems to be Solved by the Invention] In a yarn doubling machine based on the background of the prior art, a device for detecting yarn breakage, a device for detecting yarn defects, and a device for winding a yarn package into a fixed length are each independent of each other. Therefore, measures such as using these devices individually and repeating the thread winding process, or installing two types of these devices redundantly on one thread doubling machine are taken. Ta. Therefore, the installation of these devices in the doubling machine is complicated, the workability is poor, the performance of each device is unsatisfactory and unstable, and the biggest problem is the high cost. The present invention solves the problems of the prior art by providing a device that integrates a yarn breakage detection function, a yarn defect detection function, and a fixed length winding function for winding yarn. In addition to finishing the yarn package by doubling yarn without defects and winding it to a certain length, it has a simple structure, is inexpensive, is easy to handle, and can be detected without contacting the yarn. It is an object of the present invention to provide an ideal yarn winding monitoring device for a yarn doubling machine that is not affected by the external atmosphere such as temperature, vibration, etc., and can be installed in any yarn doubling machine including high-speed yarn doubling machines. [Means for solving the problem] For this purpose, the present invention provides a doubling machine that
a detection section disposed corresponding to each single yarn of each doubling yarn wound by being driven by each drum, a rotation detection section that detects rotation of a shaft that drives the drum, and the rotation detector; comprising a connected control unit and an amplification unit that amplifies the output signal of each of the plurality of detection units and sends input from the control unit to each display and each of the detection units, respectively, The detection section is composed of an electronic thread irregularity detector and a thread cutter, and the control section is composed of a constant length setting device including a multiplier, a frequency divider, etc., a thick thread detection setting device, and a stabilized power supply. The amplifying section is composed of an amplifying device, a NAND circuit, an AND circuit, a comparator, a counter, and a relay circuit, and the output of each thread spot detector in the detecting section is the amplifying section. The outputs of the amplifiers are connected to the inputs of the NAND circuit, the AND circuit, and the comparator, respectively, and the constant length setting device, the thick thread detection setting device, and the stabilized power supply in the control section are connected to the amplifier. The output of the AND circuit in the amplifying section is connected to the input of the AND circuit, the input of the comparator, and the power supply of each device in the amplifier, respectively, and the output of the AND circuit in the amplifying section is connected to the input from the fixed length setting device. The outputs of the NAND circuit, the comparator and the counter are connected to the relay circuit and the display, and the outputs of the NAND circuit, the comparator and the counter are connected to the relay circuit and the display. The output of the circuit is connected to the yarn cutter in the detection section, and the output signal of the relay circuit operates the yarn cutter to cut the single yarn, and the display detects yarn breakage and indicates whether the yarn is broken or not. The present invention is characterized by a configuration in which the details of yarn cutting due to detection and yarn length full winding are displayed. [Examples] Hereinafter, examples of the present invention will be described with reference to the drawings.
This will be explained along with its effect. FIG. 1 is an electrical configuration diagram of an example of a winding monitoring device according to the present invention. In the figure, single yarns 3 1 and 3 2 are doubled by a guide 26 and placed on a bobbin 27 driven by a drum 1. It is wound up as doubling thread 2. Detectors 6 1 and 6 2 are installed corresponding to the single yarns 3 1 and 3 2 , respectively. The detection units 6 1 and 6 2 are electronic thread spot detectors 4 1 and 4 2
The yarn unevenness detectors 4 1 and 4 2 are, for example, optical detectors, which run the single yarns 3 1 and 3 2 between the transmitter and the receiver, respectively , and measure their outer diameter . The thread cutters 5 1 and 5 2 are constructed of an electromagnetic solenoid and a cutting blade that is linked to the electromagnetic solenoid. It has a structure in which it is operated to cut the single yarns 3 1 and 3 2 . The thread mottling signals detected by the thread mottling detectors 4 1 and 4 2 are amplified by the amplification devices 7 1 and 7 2 in the amplifying section 14, respectively, and converted into direct current. The amplification unit 14 includes amplification devices 7 1 , 7 2 , a NAND circuit 8 ,
AND circuit 9, comparators 10 1 , 10 2 , counter 1
1 and a relay circuit 12, and the yarn uneven signal amplified by amplifiers 7 1 and 7 2 and converted into a direct current is applied to one input of a NAND circuit 8. While both the single yarns 3 1 and 3 2 are running, the output of the NAND circuit 8 is at the (0) level. When the output becomes the (0) level, the output of the NAND circuit 8 becomes the (1) level and sends a signal to the relay circuit 12. Therefore, the relay circuit 12 generates an output and operates the yarn cutters 5 1 , 5 2 in the detection units 6 1 , 6 2 connected to the relay circuit 12 to cut the single yarns 3 1 , 3 2 . . In a general doubling machine, when the single yarns 3 1 and 3 2 are cut, the lever 28 operates to move the bobbin 27 to the drum 1.
The action is taken to interrupt the winding thread by removing it from the thread. That is, when either of the single yarns 3 1 and 3 2 is cut, the single yarns 3 1 and 3 2 are cut by the yarn cutters 5 1 and 5 2 , and the double yarn 2 is wound up in the form of a single yarn. Prevented. In FIG. 1, the output signals of amplifiers 7 1 and 7 2 are connected to one input of comparators 10 1 and 10 2 , and comparators 10 1 and 10 2 are connected, for example, as shown in FIG. Furthermore, it is composed of a time constant circuit 29 and a comparison circuit 30. The yarn unevenness signal detected during normal yarn running is relatively small and has a short duration. Therefore,
The output potential of the time constant circuit 29 is low, and the comparator circuit 30
No output signal is generated. Now, when a thick thread-like yarn defect passes through either of the thread spot detectors 4 1 and 4 2 , a relatively large and persistent thread spot signal is applied to the input of either of the comparators 10 1 and 10 2 , and the time constant circuit 29 is charged and exceeds the comparison potential of the comparison circuit 30, the comparison circuit 30 sends an output signal to the relay circuit 12. As a result, the thread cutter 5
1 and 5 2 to cut the single yarns 3 1 and 3 2 . The comparison potential of the comparison circuit 30 is variably set by a thick yarn detection/setting device 22, which will be described later, so that the limit of the size of the thick yarn can be selected. Regarding the structure and operation of the comparators 10 1 and 10 2 , various other devised systems have been considered depending on the shape of the defective yarn portion, but since these are not essential parts of the present invention, detailed examples will be omitted. do. In Figure 2, S
indicates an input terminal, P indicates a comparison potential terminal, and O indicates an output terminal. As shown in FIG. 1, a rotation detector 16 is provided corresponding to the shaft 15 that drives the drum 1. The rotation detector 16 is composed of a permanent magnet 31 and a Hall IC 32 fixed to the shaft 15, as shown in FIG. It's getting old. The output pulses of the rotation detector 16 are multiplied by the number of pulses per unit length by a multiplier 17 in the control section 24. The control unit 24 includes a multiplier 17 , a frequency divider 18 , a fixed length setter 21 including a unit length setter 19 and a total length setter 20 , a thick thread detection setter 22 , and a stabilized power supply 23 . The length L 0 of one rotation of the drum is determined from FIG. That is, if the diameter of the drum 1 is D, the traverse width of the winding thread 2 is W, and the number of rotations of the drum 1 per one round trip of the traverse is n, then the thread length L0 per one rotation of the drum is
