As is well known, a tank for storing and storing flammable liquids is equipped with a flame arrester to prevent an explosion accident. The frame element, which is a key component of the flame arrester, has an outer plate of 0.2 mm in thickness and 25 mm in width. The inner corrugated plate-like firming plate, which has a bottom side of 2 mm and a height of 0.9 mm and a width of 25 mm, is stacked and wound in a pipe shape.

Such flame prevention device frame elements must have a constant distance between the flat plate and the firming plate so that the flame is not backfired when the explosion is installed in the flammable low-pressure fuel tank. As the plate and firming plate are fixed by welding with a pipe and fixed to the center of the rotary plate, the frame element is manufactured by manually pulling the flat plate while rotating the rotary plate to make the frame element between the plate and the firming plate. The gaps were inconsistent.

As shown in the drawing, a proximity sensor indicator, a motor operation indicator, a linear speed and torque setting regulator of a flat plate, and automatic control ON are shown. / OFF switch It consists of manual speed and torque setting regulator of motor, manual control ON / OFF switch, ram cylinder manual control, main S / W and other emergency switch LCD keyboard to form a panel that commands the control device. The sensor indicator is divided into frame element, plate, firming plate, and material plate indicator. Motor operation indicator is divided into element motor, flat motor, firming motor, and reaming motor indicator. It is on when each motor is operated. And the linear speed and torque setting regulator of the plate inputs the linear speed and torque of the plate as voltage during automatic control. On the other hand, the automatic control ON / OFF switch turns on / off the servo of the element motor driver and the flat motor driver during automatic control. It is divided into element motor, flat motor, firming motor, and automatic / manual (ON / OFF). Automatic control is started only when the firming motor is ON by pressing the automatic / manual switch. In other words, frame elements can be automatically created.

On the other hand, all switches are turned off when you press OFF. Manual speed and torque setting controller of motor is divided into element motor speed, element motor torque, plate motor speed, and plate motor torque. It controls the speed and torque of each motor when making frame element manually. Manual control ON / OFF switch is for element motor-forward rotation, element motor-reverse rotation, plate motor-forward rotation, plate motor-reverse rotation, leaflet motor-forward rotation, firming motor-forward rotation, element motor servo ON / OFF plate It is divided into motor servo ON / OFF, and when the leaflet motor-forward rotation and firming motor-forward rotation are pressed, operation starts immediately.

On the other hand, the principle of the automatic manufacturing device of the frame element for flame prevention device for producing the frame element (1) is that the rotational speed of the element motor (10a) to 80% of the rated rotational speed of the motor and the torque of the motor frame element during work Is determined by considering the radius and the input pulling force, and the torque of the plate motor is 80% of the rated torque and the rotation speed is calculated by considering the radius of the plate placed for the plate rotating plate and the input plate linear speed. The frame velocity is determined to maintain the linear velocity and pulling force of the plate during operation while maintaining their magnitude. In other words, if the rotation speed of the element motor, which makes the frame element by winding the flat plate and the firming plate, is very large and the torque is reduced, and the torque of the flat motor is increased and the rotation speed is reduced, the element motor rotates at a very high rotational speed. Since the torque of the motor is very large, the linear speed of the plate is determined by the plate motor, and the pulling force of the plate is determined by the element motor, so the linear speed and pulling force of the plate are constant.

And in order to keep the linear speed of the plate constant, the torque of the plate motor must be set very large and the rotational speed must be adjusted. The formula for calculating the rotational speed of the plate motor during operation is as shown in [Equation 1].

In order to maintain a constant pulling force of the flat plate, the rotation speed of the element motor 10a should be set very large and torque should be adjusted. The equation for calculating the torque of the element motor during operation is as shown in [Equation 2].

[Equation 1]

Where RPM is the rotational speed of the plate motor 20a per minute, v is the linear velocity of the input plate 20d, r is the radius of the plate 20d placed on the plate rotating plate 20b in the working state, and ro is the plate rotating plate 20b. It is the initial radius of the plate 20d placed on the plate.

[Equation 2]

T = R × F, R = R 0 + 0.0011 × number of turns of the frame element (1)

Where T is the torque of the element motor 10a, R is the radius of the frame element 1 during operation, R0 is the radius of the initial input pipe 10g, and F is the pulling force of the input plate 20d.

Therefore, based on the information set in order to produce the frame element (1), the control device is a winding device for winding the frame element, the unwinding device for controlling the flat speed and pulling force of the flat plate and the firming device to firm the plate The material feeder that supplies the plate to the firming device automatically provides the firming plate and feeds it to the winding machine to automatically wind the frame elements, and to straighten and cut the firming plate (wrinkled plate) according to the command of the panel which commands the controller. Frame elements can be automatically produced by straightening and cutting the firming plate using a restoring and cutting device.

In addition, the frame element may be manufactured by manually manipulating the winding device, the unwinding device, the firming device, the material supplying device, and the restoring and cutting device for straightening and cutting the firming plate by using the manual operation devices of the panel which commands the control device.

As described above, the automatic production apparatus of the frame element for flame prevention device according to the present invention is based on the information set for producing the frame element, the control unit is wound around the frame element, the device to unwind the flat plate and the line speed of the plate Firing device which controls the pulling force to be constant and flat plate and material feeding device which supplies flat plate to perming device automatically produces frame and feeds it to the winding device to automatically wind the frame element and give command to the control device. It can be used as a device that can automatically produce frame elements by straightening and cutting the firming plate by using the restoring and cutting device to straighten and cut the firming plate according to the command of the control panel.

In addition, by using manual control devices of the control panel to give command to the control device as needed, the frame element can be operated by manually operating the winding device, the unwinding device, the firming device, the material supply device, and the restoring and cutting device for straightening and cutting the firming plate. Since the present invention can be used as a device capable of manufacturing, the present invention not only maintains a constant gap between the flat plate and the firming plate when manufacturing the frame element, and also has the advantage of improving the product and productivity.
