Description

An electronic acuating system of the two for one twisting yarn machine and the device for controlling it}

The present invention relates to an electronic driving system and a control method of a two-point gun twister, and to simplify the structure of the two-point gun twister significantly reduces the failure rate, while the individual motors are individually provided for the rotation drive shaft of the spindle, drum, traverse guide It can be driven by the motor and the motor can be controlled by the electronic control system, so that the productivity and quality can be further improved, such as the ease of operation, the quick setting of working conditions and the precise setting of the thread twist. The electronic driving system of the two-pore twister can not only have superior performance compared to the existing two-pocket one, such as the real-time checking of the driving state and working conditions, but also have a greater effect when producing small quantities of various types of products. The control method is related.

Conventional two-point guns are used to drive each of the spindle, the drum shaft, and the rotation axis of the traverse guide by using the power generated from one drive motor, wherein the rotation direction and ratio required by each rotation shaft is not only different Since the drive must be continuously connected with only one power, the drive transmission process is very complicated as shown in FIG. 1.

That is, it can be seen that a large number of gears, pulleys, chains, belts, etc., which are large and small, are provided and engaged with each other to perform power transmission, deceleration, rotation direction change, and the like.

Such a conventional twister can be driven at the same time by driving only one drive motor, but the entire rotating shaft can be driven at the same time. However, there is a gap and gap between many components, maintenance inefficiency for smooth operation, excessive power consumption, etc. In addition, due to the difficulty of setting the precise twist of the thread, there are many difficulties in producing a high-quality winding package, and in the event of a failure during operation, only a trained mechanic was able to repair it, as well as any one of its components. Even if there is a failure in the component and it is not operated or there is a malfunction, it will be operated until it is confirmed by the operator.

In addition, as each spindle, the rotating shaft of the drum, the traverse guide, etc. are operated by one power, it is necessary to adjust the rotational speed of each rotating shaft individually for the purpose of fine-tuning the number of twists of the thread, or to repair or commission the test. There is a need to operate the system, but it cannot be expected with the conventional system as described above, and it will be called an irrational system that reverses the reality of building an automation system in accordance with the development of the industry.

Accordingly, in the present invention, to solve the above problems, by installing a separate drive motor to drive each of the spindle, the rotation axis of the drum, the traverse guide, which is the main drive shaft of the twisting machine, the convenience of driving and operation, It has a simplified structure with ease, and enables to set a more precise number of twists of the yarn to produce a high quality winding package, and it is possible to check the real-time driving state and working conditions by the driving method by the electronic control system. It was completed as a technical task with the main focus on providing a superior function of the existing gunpo gunner.

(M2) a rotation detector (140, 141, 142) is provided on one side and one side of each rotation driving device of the cam shaft (45), respectively;

The drive controller 100 includes a display display device 110, a central processing unit 120, an inverter 1 130, an inverter 2 131, an inverter 3 132, a rotation detector 1 140, a rotation detector 2. 141, the rotation detector 3 (142), each of the inverters 1, 2, 3 (130, 131, 132) is a spindle drive motor (M1), drum rotary shaft motor (M2), traverse guide operation motor (M3) and It is provided between each wiring connected between the central processing unit (120).

The electronic driving system and the driving control method of the two-pore twister with such a configuration are driven by receiving signals from the inverters 130, 131, and 132 in three driving rotations, unlike the conventional method of driving the entire system as one driving motor. Each drive motor, that is, a spindle drive motor (M1), a drum rotating shaft motor (M2), and a traverse guide operation motor (M3) are provided so that each rotating unit is operated directly and generated in one motor as before. The large and small gears, pulleys, chains, belts, etc. needed to transfer and decelerate the power, and to change the direction of rotation are eliminated at all, which greatly simplifies the structure, thus reducing the time required for the corresponding working conditions. Of course, this provides many advantages in reducing and maintaining the failure rate.

In addition, by adopting individual driving method that starts and drives individual motors (M1, M2, M3) installed in each rotary drive unit, it achieves smooth driving and precisely adjusts the number of threads and sets working conditions. It also offers advantages such as ease of operation and simplicity of operation (operation).

In addition, the rotational driving unit and the operation of the machine are provided through rotation detectors 140, 141, and 142 provided at one end of the belt tension pulley 90, one side of the drum rotating shaft driving motor M2, and one side of the cam shaft 45, respectively. It is possible to check the status (spindle rotation speed, thread twist, ridge angle, thread twist direction, yarn speed, thread winding, production amount, operating time, etc.) in real time, and some operations stop or partial malfunction due to failure. Even if there is, it is possible to immediately check by the rotation detector to stop the whole rotation drive unit to prevent in advance product defects due to partial failures and malfunctions, and further expanded mechanical failure,

In addition, the start of each motor M1, M2, M3 is performed by the central processing unit (CPU) 120 in the drive control apparatus 100 through the inverters 130, 131, and 132 according to the driving conditions required by each rotating unit. If you want to be able to be driven, of course, to change the number of twist of the thread necessary for this simply by changing the number of rotation of the selected drive motor (M1, M2, M3) in the central processing unit 120 through the inverter (130, 131, 132) Just send a signal to the corresponding motor (M1, M2, M3),

In addition, since the driving of each motor (M1, M2, M3) provided in each of the rotating units can be individually adjusted by the central processing unit 120, the desired thread twist can be set more precisely, and the thread twist You can freely choose a number in a simple way.

That is, in the related art, since each rotation part connected in parallel and parallel to the motor is simultaneously started by the power generated by one motor, the rotation speed of the other rotation parts connected to the motor is determined according to the rotation speed of the motor. In order to change the speed, the rotation speed should be changed by replacing the geared or interdented gears provided between each rotating part, and calculating the reduction / acceleration ratio according to the desired number of twists. Not only is it difficult to select, but it is relatively cumbersome to replace, and the range of selection is relatively narrow. However, the drive system of the present invention can drive each motor as well as each individual drive by an electronic input method, as is well known. Of course, the choice of twist is quite large.

This improves the twisting quality of the yarn, which greatly contributes to the production of a good winding package, and has a huge impact on improving productivity, reducing costs and increasing work efficiency.

The electronic drive system and the drive control method of the two-pore twister of the present invention having the configuration and operation as described in detail above are driven by an electronic input method and an electronic control system as well as individually driving each motor provided in each rotating unit. It is possible to set and change / adjust spindle rotation speed, thread twist and direction, ridge angle, and yarn speed more easily, which will contribute to productivity improvement by speeding up working conditions. It is expected to produce winding packages of excellent quality, such as setting and adjusting the number of twists of the thread more precisely and variously, and real-time checking of the operation status of the twister during operation by the rotation sensor. At the same time, emergency measures such as stopping all rotational drive parts in case of abnormality are made. Can prevent malfunction and failure due to such a non-drawn, and is yet simple structure by significantly the forward bar of the invention is indeed such as reduced failure rate.
