Description

TWO LIQUID MIXER AND DISPENSER SYSTEM}

The present invention relates to a two-liquid mixing device for mixing two different kinds of raw materials, the main material and the hardener, and more specifically, the main material and the hardener are properly pumped by the fail pump, and the mixing process can be confirmed in the mixer. It relates to a two-liquid mixture dispensing apparatus that can confirm the operation of.

In general, the two-liquid mixing device is a device for sucking and discharging two raw materials, a main ingredient, a curing agent, and mixing them at a constant ratio.

1 is a view showing for explaining the fluid flow of the conventional liquid-liquid mixing device.

Here, the tank 10 has a closed space in which the motor 11 is mounted on the upper part, and the impeller 12 is mounted on the output rotation shaft of the motor 11 in the closed space.

The vacuum pump 13 is connected to the tank 10 through the suction line 14 so as to suck the air in the tank 10 and to form a vacuum therein, and a vacuum in the middle of the suction line 14. The bottle 15 is installed.

The mixer 20 discharges the mixed mixture as the rotating mixture is rotated by the motor 22 in the outer case 21, which is connected to the lower end of the tank 10 and the raw material supply line 31. A pump 32, a first pressure switch 33, a pressure gauge 34, and a selector valve 35 are installed at 31, and a raw material supply line 31 between the pump 32 and the mixer 20 is provided. The metering valve 36 is installed in the pump 32 to check whether the raw material is quantitatively drawn out by driving the pump 32.

The gun valve 40 is connected to the discharge end through the discharge line 41 to control the discharge of the mixed raw material by the mixer 20, and the nozzle is moved and opened and closed in the direction of the center line inside the valve body. It is equipped with a spring to elastically press.

The washing liquid container 50 is connected to the selection valve 35 of the raw material supply line 31 through the washing line 52, and the washing line 52 has an air line 53 on the high pressure vessel (not shown) side. There is a line having a washing liquid valve 55 and a check valve 56 so that the washing liquid of the washing liquid container 50 is supplied by the air supplied through the air, and the other line is a pneumatic valve 57 so as to flow with the air line 53. Branched to have

In the conventional liquid-liquid mixing apparatus configured as described above, a predetermined raw material is inserted into the tank 10 in a state in which the valve on the raw material supply line 31 is closed, and then the motor 11 is driven to drive an impeller (11) of the motor 11. As the 12 is rotated, the raw material is stirred and the vacuum pump 13 is driven while stirring the raw material. Thus, the air inside the tank 10 starts to be sucked.

The air that has begun to be sucked from the tank 10 is sucked into the vacuum pump 13 through the vacuum bottle 15 on the suction line 14, so that the inside of the tank 10 is in a vacuum state and maintained for a predetermined time. To remove bubbles contained in the raw materials.

Thus, after removing the air bubbles contained in the raw material in the tank 10, the operation of the vacuum pump 13 is stopped or the valve of the suction line 14 is closed and the vacuum in the tank 10 is gradually released.

After the vacuum in the tank 10 is released and the pump 32 is driven while the valve on the raw material supply line 31 is opened, the raw material in the tank 10 is pumped to supply the internal material in the raw material supply line 31. When the pressure reaches the set pressure, the driving of the pump 32 is stopped by the first pressure switch 33. When the pressure inside the raw material supply line 31 is lowered, the pump 32 is driven to always maintain the predetermined pressure.

As such, when the inside of the raw material supply line 31 reaches the predetermined pressure, the metering valve 36 is opened and sampled to confirm that the quantitative discharge is performed, and then locked, and then the raw material supply line 31 to the mixer 20 by the selection valve 35. Open to supply internal raw materials. When the main material and the curing agent supplied in each of the raw material supply lines 31 are press-fitted into the mixer 20, they are evenly mixed by the rotary mixture of the mixer 20.

The mixed raw materials are moved to the gun valve 50 along the discharge line 41 and the discharge end of the gun valve 50 is placed at the position where the mixed raw material is to be discharged. When the air is supplied, the nozzle is raised so that the mixed raw material is discharged through the nozzle cap.

In this way, after discharging a predetermined amount of the mixed raw material, when the high pressure air supplied to the valve body of the gun valve 50 is blocked, the nozzle is returned to its original position by the spring elasticity to block the discharge of the mixed raw material.

When the blender 20 and the gun valve 50 are to be washed after completing the above operation, the selector valve 35 of the raw material supply line 31 is manipulated so that the blender 20 and the washing line 52 are distributed. While supplying a high pressure air to the air line 53 alternately for a predetermined time, the washing liquid valve 55 and the pneumatic valve 57 is operated in reverse.

When only the washing liquid valve 55 is opened, the pressure is applied to the washing liquid surface of the washing liquid container 54 so that the washing liquid is discharged through the washing line 52-the mixer 20-the discharge line 41-the gun valve 50. When only the pneumatic valve 57 is opened and the high pressure air is discharged through the air line 53-the washing line 52-the mixer 20-the discharge line 41-the gun valve 50, the washing is repeated. This is done.

However, in the conventional liquid-liquid mixing and discharging device as described above, a device for removing bubbles contained in the raw material forms a system, and the equipment is enlarged, and after the raw material in the tank 10 is used up, the tank 10 again. During the process of adding raw materials and removing bubbles, the equipment had to be stopped, resulting in a decrease in productivity.

In addition, since the outer case 21 of the rotating mixture constituting the mixer 20 is formed of an opaque metal, even if the rotating shaft portion of the rotating mixture is damaged, the rotating shaft portion of the rotating mixture is damaged and thus the raw materials are not mixed properly. There was a problem that can not prevent poor mixing.

In addition, even though the cleaning liquid inside the cleaning liquid container 50 is cleaned of the gun valve 40 through the washing line due to the air pressure applied to the cleaning liquid container 50, the mixed raw material remains at the operating part of the gun valve 40. The nozzle of the valve 40 may not operate, and if the gun valve 40 is not operated, the pressure continues to rise in the raw material supply line 31, resulting in the first pressure switch 33 on the raw material supply line 31. Since the pump 32 is not driven by), the hassle has to be re-washed or replaced.

The purpose of the present invention is to research and develop in order to solve the conventional problems as described above, plug the fail pump directly to the raw material packaging container of the bubble is removed, so that the raw material supply to the mixer can be made to miniaturize the equipment A lyotropic liquid dispensing device is provided.

In addition, another object of the present invention is to provide a two-liquid mixed dispensing apparatus for providing a second pressure switch in the raw material supply line that is the discharge portion of the fail pump to check whether the main or hardener is properly pumped.

Another object of the present invention is to prepare a rotary mixture of the mixer and the outer case of the stationary rotating body of the transparent material of tempered glass or plastic type so that the blending process of the raw materials in the mixer as well as whether the mixer is broken or not. It is to provide a discharge device.

Another object of the present invention is to provide a nozzle operation detecting sensor outside the valve body of the gun valve to check whether the nozzle inside the valve body to operate, thereby preventing any abnormality or damage of the device in advance. It is to provide a liquid mixture discharge device.

Reference numeral 38 in the figure denotes a main valve on the raw material supply line 31a.

The liquid-liquid mixed dispensing apparatus of the present invention configured as described above first completes the operation of removing bubbles in a vacuum or by heating while placing the raw material packaging container 31a on a rotary table of the bubble remover.

When the bubble pump 100 is inserted into the raw material packaging container 31a in which the bubble removal operation is completed and the fail pump 100 is operated, the raw material is sucked out and the raw material supply line 31a is discharged, thereby providing a second material on the raw material supply line 31a. The pressure is increased to the pressure set in the switch 37.

When the fail pump 100 operates when the rod 105 of the stroke variable cylinder 104 is raised, the raw material of the raw material packaging container 60 is sucked and started to descend as the hollow piston 103 is raised. Since the suction valve starts to be pressurized by the hollow piston 103 and the check valve 101 at the bottom of the cylinder 102 is locked, the suction raw material in the cylinder 102 is discharged from the raw material discharging end 106 of the upper portion of the cylinder 102. The discharge is supplied to the raw material supply line (31a) through.

As this process is repeated, the suction raw material is continuously supplied, so that after the pressure of the raw material supply line 31a is increased, the fail pump 100 is properly operated, and then the main valve 38 is opened to open the raw material supply line 31a. As the pressure of the lower pump 100 is operated again, starting to supply to the selection valve 35 through the raw material supply line (31a).

When the raw material is supplied to the raw material supply line 31a as described above, the pump 32 is driven, and when the pressure inside the raw material supply line 31a becomes the set pressure by the pump 32, the pressure switch 33 The signal is sent to the control unit which stops driving the pump 32. When the pressure inside the raw material supply line 31a is lowered, the pump 32 is driven to always maintain the predetermined pressure.

As such, when the inside of the raw material supply line 31a reaches the predetermined pressure, the metering valve 36 is opened and sampled to confirm that the quantitative discharge is performed, and then locked, and then the raw material supply line 31a is fed to the mixer 20a by the selection valve 35. Open to supply internal raw materials. When the main material and the curing agent supplied in each of the raw material supply lines 31a are press-fitted into the mixer 20a, they are evenly mixed by the rotating mixture 24 and the stationary rotating body 25 of the mixer 20a. At this time, since the rotary mixture 24 and the stationary rotary body 25 of the mixer 20a are enclosed and the outer cases 21 and 26 are made of a transparent material of tempered glass or plastic type, the rotary mixture 24 and the stationary mixture ( 25) You can check the operation or damage.

The mixed raw materials are moved to the gun valve 40a along the discharge line 41, and the discharge end of the gun valve 40a is positioned at the position where the mixed raw material is to be discharged, and the valve body 42 of the gun valve 40a is discharged. When the high pressure air is supplied to the nozzle 43, the nozzle 43 is raised, and the mixed raw material in the valve body 42 is discharged through the nozzle cap.

In this way, after discharging a predetermined amount of the mixed raw material, the high pressure air supplied to the valve body 42 of the gun valve 40a is shut off, and the nozzle 43 is returned to its original position by the elasticity of the spring 44, thereby preventing the mixed raw material. Shut off the discharge. At this time, the magnetic sensor switch 46 outside the valve body 42 detects the flow of the nozzle 43 inside the valve body 42 and sends a detection signal to the control unit to inform whether the nozzle is operating.

In other words, when the nozzle 43 inside the valve body 42 flows, the mixed raw material of the raw material supply line 31a cannot be discharged when the nozzle 43 is not in a normal operating state. Damage or defect can be prevented in advance.

When the mixer 20a and the gun valve 40a are to be washed after the above work is completed, the selection valve 35 of the raw material supply line 31a is operated so that the mixer 20a and the washing line 52a are distributed. When the high pressure air is supplied to the air line 53, the washing liquid valve 55 of the washing liquid line 54 and the pneumatic valve 57 of the air line 58 alternately operate for a predetermined time.

When only the washing liquid valve 55 of the washing liquid line 54 is opened, the pressure is applied to the washing liquid surface of the washing liquid tank 50 so that the washing liquid is washed liquid line 54-mixer 20a-discharge line 41-gun valve. When the air is discharged through the 40a and only the pneumatic valve 57 of the air line 58 is opened, the high pressure air is discharged through the air line 53-the mixer 20a-the discharge line 41-the gun valve 40a. The process is repeated so that the washing is made.

Unlike the prior art including a bubble remover as described in detail above, the lyotropic liquid dispensing apparatus of the present invention saves time by separately preparing a bubble remover so that bubbles in the raw material can be performed before or during the operation. Work efficiency and productivity can be improved, and raw materials are supplied to the mixer by directly inserting the fail pump into the raw material packaging container in which the bubble removal is completed, so that the equipment can be miniaturized.

In addition, the present invention provides a pressure switch in the raw material supply line, which is the discharge part of the fail pump, to check whether the main material or the hardener is properly pumped, and the outer case of the rotating mixture of the mixer and the stationary rotating part is made of tempered glass or plastic. By providing a transparent material, it is possible to check the blending process of raw materials in the blender as well as whether the blender is broken.

In addition, the present invention provides a nozzle operation detection sensor outside the valve body of the gun valve to check whether the nozzle inside the valve body is operating, thereby preventing the abnormality or damage of the device in advance.
