The principle of filling machine you know?

Filling machine filling method:

1) Normal pressure method
Normal pressure method, also known as pure gravity method, that is, under normal pressure, the liquid material to rely on self-weight flow into the packaging container.Most of the free flow of gas-free material can be filled with this method, such as liquor, wine, milk, soy sauce, vinegar and so on.
(2) isobaric method
Equal pressure method, also known as pressure gravity filling method, that is, higher than atmospheric pressure conditions, the first charge of the packaging container, so that the formation of the tank with the same pressure, and then rely on the infusion of pouring material into the weightInside the packaging container.This method is generally used for gas-containing beverages such as beer, soft drinks, sparkling wine and other filling.The filling of this method can reduce the loss of CO2 contained in such products and prevent excessive foaming during filling and affect product quality and quantitative accuracy.
(3) Vacuum method
Vacuum method is carried out under the conditions of less than atmospheric pressure, can be carried out in two ways:
(A) Differential pressure vacuum type
That is, the tank is at atmospheric pressure, only the packaging container to make a vacuum, liquid material to rely on the tank and the pressure difference between the container to produce flow to complete the filling, domestic this method is more commonly used.
(B) gravity vacuum type
That is, the tank is in a vacuum, the packaging container is first pumped to form a vacuum equal to that in the tank, and then the liquid material flows into the packaging container by its own weight, because the structure is more complicated and less domestic.Vacuum filling a wide range of applications, it is suitable for filling a slightly larger viscosity of liquid materials, such as oil, syrup and so on.Also suitable for filling vitamins containing liquid materials, such as vegetable juice, fruit juice, etc., the bottle to form a vacuum means that the liquid material to reduce the contact with the air to extend the shelf life of the product, vacuum method is also suitable for filling toxicMaterials such as pesticides, etc., to reduce the spill of toxic gases, improve working conditions.
(4) pressure method
The use of mechanical pressure or pressure, the irrigation material will be squeezed into the packaging container, this method is mainly used for filling thick viscous materials, such as filling tomato sauce, meat emulsion, toothpaste, balsam and so on.And sometimes can be used for soft drinks a soft drink filling, then rely on the pressure of the water itself directly into the bottle without inflatable pressure, which increased the filling speed, the formation of the bubble because of the colloid is still easy to disappear,On the filling quality have a certain impact.
In this paper, the filling method of filling machine is determined:
For the general consumption of liquid materials such as bottled milk, bottled alcohol, carbonated drinks, etc., can be used to fill the pressure method, vacuum filling method, but taking into account the cost of isobaric filling method can effectively reduce the loss of CO2,To maintain the quality of gas-containing drinks, and to prevent excessive filling in the bubble, to ensure accurate filling measurement.Therefore, this paper uses isobaric filling method.
The bottle in the filling machine in turn: 1, into the air, 2, into the liquid back to the gas; 3, stop the liquid; 4, remove the remaining liquid 4 steps.At the same time the production line of a variety of detection status sensors all access to the PLC, the PLC according to the sensor detection status through the preparation of a good program to control the entire system work.
Filling valve components from the liquid valve, gas pipe, valve, centering cover, exhaust valve and other components
PLC acquisition signal:
1. Filling machine bottle tray pressure
2. Centering pressure
Air pressure
4. defective picker pressure
5. Maximum hydraulic pressure
6. Minimum hydraulic pressure
PLC output signal:
Conveyor belt
2. bottle tray
3. Valve
4. Filling the valve
5. defective lights
6. defective conveyor belt
7. defective picker
8. Feeding valve
9. return air tube
10. Gripping machine
11. Packaging machine
Normal workflow
Press the start button to transfer the wheel and the filling machine to start.Then press the conveyor start button, filling machine into the bottle conveyor belt start.After the bottle enters the conveyor belt, the bottles are equally spaced into the bottle tray lifting mechanism by passing the wheels.When the tray detects the pressure, the pallet piston gives the pallet lift a pressure, and the tray begins to take the bottle up.In the time of the rise of the tray, the maximum rise time is 6S. If the pressure is detected, the tray will stop rising and then the valve will open to start filling the bottle.The maximum inflation time is 6S.When the valve to detect the pressure, then stop charging CO2, the liquid valve open, start filling.Filling time is 6S.After filling, the tray begins to drop, the process of lowering the liquid valve at the same time, the return air pipe work, open the exhaust and remove the liquid operation.The finished bottle is then passed through a certain angle and is sent by the delivery wheel, and the bottle tray continues to move forward into the next cycle.

When a defective is detected:
1. When the defective bottle is used
When the maximum filling time is increased by 6S, the pressure is not detected when the maximum level of the tray is increased (the bottle is a burst bottle, the height is insufficient), the tray starts to drop, and the defective light is on and the tray is lowered 6S. Decrease the tray to wait for the next cycle. At the same time defective detector start.
2. When the defective bottle is broken:
Then the normal filling process, when the maximum inflatable time 6S to the time, the valve did not detect the pressure (broken bottle, CO2 filled dissatisfaction), then stop charging CO2, while the bottle tray began to decline, defective lights, tray down time 6S , The drop down the tray waiting to enter the next cycle, while defective detector start.
