Description

Operation system of warping machine and beamer machine {Operation system of warping machine and beaming machine}

The present invention relates to a drive system for a cruiser and a beamer, and in particular, a transmission is installed in the drive unit of the racer, and the gearbox is shifted to one gear when the gear is fixed and the gear ratio is increased to two gear when the gear is fixed. Compensation for the rotational torque of large drums.Beaming can be done automatically by constant velocity and isotonic power by electronically controlling the vector motor of the regular and beaming machines with the thread speed and tension detector of the thread installed in the beaming machine. The automatic beaming is performed without manual tension compensation until the end of work.

Conventionally, the warp machine and the beamer have been a semi-automatic method of manually controlling the drive motor of the beamer and the drum brake (hydraulic or pneumatic) of the warp machine to uniformly maintain the tension of the yarn wound by the beamer.

Therefore, as the diameter of the beam changes, the tension and speed of the yarn change, so a skilled worker needs to uniformly adjust the beaming tension by manually manipulating the driving motor of the beaming machine and the drum brake of the warp machine based on the rule of thumb. In addition, this manual work is very cumbersome, and there is a problem that the quality of the product varies according to the worker's sense ability.

In other words, winding the thread increases the diameter of the beam, so that the pull-out tension of the drum (or krill) increases with increasing tension and volume (layer). When dyeing the fabric, there was a problem such that color and bicolor (異色) occurs and the fiber quality is greatly reduced.

Therefore, the present invention is to install a two-stage gear box in the driving unit of the warp Gyeonggi work to the first stage and the beaming work to the second stage to increase the speed ratio to be controlled by high torque and tension installed in the warp and beamer And by setting the beaming tension value by controlling the driving motors of the regular racer and the beamer through the four-speed detector to achieve the isothermal speed and isotonic force of the thread being beamed, the automatic beaming is made without compensating for tension until the beaming work is completed. For the purpose of

In addition, in some types of yarns in which the middle layer of the thread or the uppermost layer of the thread penetrates to the bottom when the thread is wound with a constant tension, and the layer of the yarn collapses, the tension is reduced by a constant linearity ratio according to the changing winding diameter. The purpose is to prevent the collapse of the layer.

On the other hand, in the case of a beating operation, if the worker's mistake requires or shortens the number of threads required by the loom, or the beam may need to be rewound due to other causes, the yarn wound on the beaming machine may be Since the reverse beaming (reverse winding process) is required to rewind to the drum, conventionally, the tension control method of the beaming machine and the regular racer is not only made separately but also a manual control method, so uniform tension control cannot be achieved during the reverse winding operation. These problems are solved when the invention is applied.

Is coupled to the spool, and the shift lever 46 is pin-coupled to an end of the rod 52 of the air cylinder 30 to move the first and second gears 48 and 50 in the longitudinal direction of the connecting shaft 34. Will be.

When the first gear shift 48 and the first gear 42 engage with each other by the action of the shift lever 46, the gear is shifted to the first gear and the second gear 50 is actuated by the shift lever 46. And second gear 44 are shifted to second gear, and if the first and second gears 48 and 50 are not engaged with the first and second gears 42 and 44, they are neutral. It is in a state.

On the other hand, the power transmission means composed of a motor 56, a reducer 58, a belt 60 and a pulley 62 to drive the beam 54 on one side of the beamer 4, the motor 56 The pulley 64 fixed to the rotary shaft of the pulley 66 and the pulley 66 fixed to the input shaft of the reducer 58 are connected by a belt 60, the output shaft of the reducer 58 and the beam drive shaft 68 is a chain coupler 70 The decelerating force of the motor 56 is transmitted to the beam 54.

In addition, one side shaft of the reducer 58 is provided with a disc brake 88 for properly braking the reverse rotation of the beam 54 when the reverse beaming, and if the worker accidentally misses a few strands of thread, reverse beaming The disk brake 88 controls the rotational force of the beam 54.

In the present invention, the motors 8 and 56 for driving the drum 8 and the beam 54 are quasi-server motors, and the rotation speed is precisely controlled by the vector inverter 62 controlled by the computer 90. .

On the other hand, Figure 3 is a circuit block diagram of the present invention, the encoder 92 for detecting the rotational speed of the drum (8) to the input of the control computer 90, the thread guide roller 94 or the diameter of the warp machine (2) It is installed on a table or a four-bed thread guide roller (or a thread guide roller installed on a stool), and connects an encoder 96 for detecting the dead thread and the dead and load cells 76 and 78 serving as tension detection means, respectively. A vector inverter 62 for controlling the motor 56 of the beamer and a servo system 98 of the body size reduction device are connected to the input / output section of the 90, and a thread to be input to the input of the vector inverter 62. An encoder 82 for sensing the tension of the encoder and an encoder 84 for detecting the rotational speed of the beam 54 are connected, respectively, and the output of the vector inverter 62 is the motor of the warp motor 8 and the beamer 56. Are connected to each other so that the beaming device 2 and the beamer 4 are linked to each other to automatically equalize the beaming tension and the beaming speed. .

In addition, the computer 90 stores individual data such as firing speed, dead center, tension and rotational speed, and arithmetic data for calculating them, thereby acquiring reference volume data for each collection.

In other words, when the first section work is performed with the warp, the work data of the warp drum is recorded (data obtained by checking the winding diameter of every president every 2 to 3 seconds) and sampled. In Cannes, the canonical work is performed by matching the volume of the drum based on the sampling data obtained from the first box.

In other words, the volume data of the first chest becomes the reference volume, and after the second chest, the sample volume is applied to make the canon so that the volume of the entire chest is the same and the outer diameter is the same. do.

In accordance with the sample data obtained from the first box, the second volume is adjusted to the same volume from the last box, and the deviation between the first box and the last box is eliminated by using the servo system 98 of the volume reducer. . The servo system 98 of the volume reduction device may be referred to as a kind of tension control device.

Reference numeral 100 is a tension adjusting device capable of adjusting the tension of the belt by moving the position of the motor, 102 is a tension holding roller, 104 is an oil coating roller, 106 is a roller.

The present invention constructed as described above uniformly beams the yarn with the concept of isometric speed and isotonic power. That is, the rotational speed of the vector motors 8 and 56 under the control of the computer 90 when beaming the yarn circumscribed to the drum 8 of the warping machine 2 with the beam 54 of the beamer 4. Since the rotational speeds of the beam 54 and the drum 8 are controlled, the beaming is achieved with uniform yarn speed and uniform tension.

First, the computer 90 sets (inputs) an appropriate beaming tension and yarn speed according to the thread type and denier value. Then, when the rod 52 of the air cylinder 30 is immersed, the shift lever 46 moves to the right. Since the second speed gear 50 and the second speed gear 44 are engaged with each other and shifted to two speeds, the rotational torque of the drum 8 having a larger diameter and a lower rotation speed than the beam 54 is compensated for.

On the other hand, when the motors 8 and 56 are driven by the beaming operation signal, the beam 8 and the drum 54 rotate in the same direction, and the beaming operation starts. The rotational speed of the drum 8 from the encoder 92 is started. The detection signal is input to the computer 90, and the dead thread and the dead thread are from the encoder 96 installed in the thread guide roller 94 of the warp machine 2 or the thread guide roller of the bed (or the thread guide roller installed on the stool). A sensing signal is input, and a tension sensing signal of a thread that is beamed from the encoder 82 of the beamer 4 is input.

The computer 90 collects the signals input from the encoders 82, 84, 86, 92 and the load cells 76, 78 to determine the current thread speed and the tension of the thread, and then goes beyond the set speed or tension. The rotation speed is varied by controlling the plane vector inverter 62 to control the drive motors 54 and 8 of the beamer 4 and the warp machine 2.

Therefore, since the rotational speed of the beam 54 and the drum 8 is automatically controlled, automatic beaming is made with uniform tension (isotropy force) and uniform firing velocity (equivalent flux). Since the problems of manually compensating for the problem are completely solved, manual tension compensation is not necessary until the end of the beaming work.

That is, the computer 90 obtains the tension signal of the thread by summing and averaging the tensions of the yarns input from the load cells 76 and 78 provided on both sides of the guide rollers. 90, if the tension inputted in comparison with the preset tension is out of the range of the set tension and the dead speed, the rotation speed (or rotational speed) of the motor 8 or 56 is adjusted, and the tension of the input thread 72 is adjusted. When (or / and four speeds) exceeds the set tension, the rotation speed (or / and rotation torque) of the motor (8) 56 is reduced, so that the rotation speed of the beam 54 and the drum (8) is reduced, the load cell 76 When the tension signal inputted from the 78 and the four speed signal inputted from the encoder 82 coincide with the tension signal set in the computer 90, the current speed of the motors 8 and 56 is maintained.

In addition, when the input tension is less than the set tension (or / and four speed), the rotation speed (or rotation torque) of the motor (8) 56 is increased, so that the rotation speed of the beam 54 and the drum (8) is increased, and the load cell When the tension signal input from the 76 and 78 and the four speed signal input from the encoder 82 match the tension signal set in the computer 90, the current speed of the motors 8 and 56 is maintained.

In addition, in the case of the conventional semi-automatic type in which the tension of the yarn wound by the beaming machine is maintained evenly by manually controlling the driving motor of the beaming machine and the drum brake (hydraulic or pneumatic) of the beaming machine, the beaming is manually performed as the diameter of the beam changes. Tension correction is not only difficult, but uniform tension compensation is difficult due to manual operation, which makes it difficult to work, and the quality is deteriorated due to uneven tension and weaving due to the worker's sense of ability. However, the present invention solves these problems neatly.

In addition, the present invention is to achieve the isotonic flux and isotonic power is achieved in the case of some kinds of yarns having a phenomenon that the middle layer of the yarn or the top layer of the yarn penetrates to the bottom when the coil is wound with uniform tension, the layer of the yarn collapses The tension is reduced at a constant linearity ratio, thereby preventing the layer of thread from collapsing.

In addition, if the number of yarns required by the loom is too small or too large, or if the beam has to be rewound due to other reasons during the beating operation, the yarn wound on the beaming machine is rewound to the drum of the warp machine. Reverse beaming (reverse winding process) is required, but in the conventional method, since the tension control method of the beamer and the regular economy is separate and is made by a manual control method, uniform tension control cannot be achieved during the reverse winding operation. The game (2) and the beamer (4) with the help of the computer 90 to maintain the same speed and appearance with the help of each other, so there is no need to take care of the beaming tension manually.

As described above, the present invention is to install a two-stage gear box in the driving unit of the warp machine to increase the speed ratio to two gears at the time of normal operation and to control the high torque by increasing the speed ratio to two gears, and to drive the drive motor of the warp machine and beamer The conventional problem of manually compensating for the tension difference according to the winding diameter is solved by achieving the isothermal speed and the isotonic force by controlling the automatic beaming.

In addition, in the case of some types of yarns in which the middle layer of the thread or the uppermost layer of the thread penetrates to the bottom when the thread is wound with a constant tension, and the layer of the yarn collapses, the tension is decreased by a constant linearity ratio according to the changing winding diameter. There is an effect that can prevent the collapse of the layer.

In addition, there is an effect such that the reverse beaming is automatically performed by the computer at the same speed and appearance power during the reverse beaming operation.
