What is a filling machine?

A filling machine is an automatic or semi-automatic device used to fill liquids, powders, granules or tablets into packaging such as bottles, jars, bags, boxes. The machine is widely used in many industries such as food, beverages, pharmaceuticals, cosmetics and chemicals.

This device helps ensure the filling process is accurate, fast and uniform, thereby optimizing production capacity, minimizing material waste and ensuring product quality.

Structure of the filling machine

There are many different types of filling machines, but in general, they include the following main parts:

• Packaging loading system: Brings bottles, jars or bags to the filling position.
• Filling system: Pumps or measures the product into the packaging according to the required capacity.
• Control panel system: Helps the operator set parameters and monitor machine operation.
• Dosing system: Ensures the exact amount of product filled as required.
• Cleaning system: Cleans the filling nozzle and the product contact area.

In addition, modern filling machines also integrate additional functions:

• Rinse and dry system: Helps clean and dry the packaging before filling.
• Bottle capping system: Automatically closes the cap to ensure product quality.
• Defective product inspection system: Eliminates substandard products, ensuring output quality.

Filling machine lines on the market today

Currently, there are 5 types of filling machines that are commonly used and chosen by many businesses, including: Gear pump filling machine, piston pump filling machine, screw pump filling machine, flowmeter filling machine, convection filling machine, etc.

1. Gear pump filling machine

Gear pump filling machine is the optimal choice for the food and cosmetic industries thanks to its precise filling ability. The machine is made of stainless steel and high-grade aluminum alloy, with a flexible design, easy to adjust to suit many different bottle sizes.

Operated through an intuitive LCD touch screen, helping users to operate simply and customize quickly. The filling system uses a rotary pump head, combined with an AC motor and inverter, ensuring a smooth flow, minimizing foaming during the filling process.

Along with a soaking nozzle design to prevent liquid from spilling out of the bottle and conveyor. The pump system and conveyor motor are equipped with comprehensive protection mechanisms, ensuring stable operation and avoiding pressure drops during operation.

2. Piston Pump Filling Machine

The piston pump filling machine, also known as the automatic filling machine, is specially designed for filling non-particle liquids such as purified water, mineral water, etc. With a modern piston pump head system, the machine ensures a stable and precise filling process.

Controlled by a servo motor, the machine provides high quantitative accuracy, meeting the requirements of products that require strict control of capacity. In particular, the protection system helps to minimize waste, while the anti-overflow nozzle ensures a clean and safe filling process. The intuitive touch screen makes it easy for users to operate and adjust parameters flexibly.

3. Screw Pump Filling Machine

The screw pump filling machine is specially designed for the filling process of lubricants, ensuring high efficiency and optimal accuracy.

Each screw pump head is independently controlled by a separate motor, helping to control the filling amount with absolute precision. The dipping nozzle system minimizes air bubbles and prevents liquid from splashing out, ensuring the quality of the finished product. Users can easily adjust and set parameters via the LCD touch screen, helping to optimize operations and improve production efficiency.

4. Flowmeter Filling Machine

The flowmeter filling machine is a quantitative filling machine, providing high accuracy and convenience in cleaning. With its optimized design, the machine is especially suitable for filling highly viscous or dense liquids.

The wide filling range, combined with the anti-foaming system, helps ensure product quality during the filling process. The modern machine structure allows for precise standard setting and adjustment of the rated flow, helping to optimize production efficiency.

5. Convection Filling Machine

The convection filling machine, also known as the isobaric filling machine, is specially designed for products such as mineral water and fruit juice. The filling capacity of the machine ranges from 500 - 1500ml, suitable for many production scales.

The soaking nozzle design helps stabilize the liquid during the filling process, prevents overflow and limits material loss. The machine is integrated with PLC control system and touch screen, helping the operator to easily adjust parameters, ensuring efficient and accurate production process.

Overview of the automation line combined with the filling machine

The automation line combined with the filling machine helps to optimize the production process, improve productivity and ensure accuracy in filling.

1. Flat belt conveyor

Flat belt conveyor is one of the popular transport systems in industrial production lines. This system helps to move products continuously and stably within the factory.

This type of conveyor operates based on a series of pulleys, pulling the flat belt made of natural materials or synthetic fabrics. The product is placed on the belt and moves from one point to another smoothly, optimizing the internal transport process.

2. Roller conveyor

The roller conveyor has a surface made of rotating rollers, helping to transport products easily according to production requirements. Depending on the weight and speed of the product, the appropriate roller type will be selected to ensure the best operating performance.

This system is especially useful in filling lines where products need to move quickly or require flexibility in speed adjustment.

3. Robotic arm

Robotic arm is an advanced technology solution that helps optimize the filling process by flexibly moving products without the need for a conveyor belt. The application of robotic arms not only helps automate the process, reduce dependence on human labor, but also increases accuracy and limits errors in production. This system also helps improve labor safety when workers do not need to directly contact the operating machinery, thereby optimizing time, increasing productivity and reducing operating costs, bringing sustainable competitive advantages to businesses.

4. Control system

The control system plays an important role in the automatic filling line, helping to optimize the operation, monitoring and ensuring high accuracy. Two popular systems applied in this field are SCADA and PLC.

SCADA (Supervisory Control and Data Acquisition) is an automatic monitoring and control system that allows real-time monitoring of equipment operating status, data collection and detailed information display. SCADA not only helps improve operational efficiency but also integrates easily with other control systems such as PLC, ensuring smooth and efficient production processes.

PLC (Programmable Logic Controller) is a programmable logic controller widely used in industrial systems, especially filling lines. PLC is capable of processing input and output signals from various devices and sensors to adjust and monitor the process. In addition, this system also provides a flexible programming environment, helping to create optimal control algorithms, improving production accuracy and efficiency.
