Automatic weigh-filling line for 20-liter open-neck plastic containers and flat plastic jerrycans

The fully automatic weigh-filling line is an integrated system for filling engine oil and a wide range of liquids with high accuracy, based on weight measurement. It is widely used in industries that need high precision and consistent fill weight, such as food, chemicals, pharmaceuticals, and oils and lubricants.

The weigh-type engine oil filling machine relies on high-accuracy weight sensors and an advanced control system that monitors the product weight in real time during filling. This delivers high accuracy and consistency of fill weight while reducing the effect of changes in product viscosity and temperature.

Filling range and output

The machine handles open-neck plastic containers and flat plastic jerrycans of 20 liters, with an output of up to 350–450 twenty-liter containers per hour, depending on the product, the number of filling heads and the operating speed. It adapts easily to containers of different shapes, sizes and specifications, and changeovers are quick, without frequent part replacement.

Main features:

• High-accuracy weigh-filling system
• An independent weight sensor for every filling head
• Anti-drip, anti-leak design
• Frame and every product-contact part in stainless steel
• Easy cleaning and maintenance
• Fill weight can be adjusted quickly and easily
• Handles containers of different sizes and shapes
• Easy-to-use HMI operator interface
• Automatic control that reduces manual intervention
• Simple to install and commission, with no lengthy operator training

How the filling machine works:

The machine runs a fully automatic cycle covering container feeding and positioning, weighing and filling, and discharge of the containers once filling is done, with minimal manual intervention.

1- Container positioning

The conveyor carries empty containers to the filling station, where the clamping system holds each one in the correct position before filling starts. The operator can easily set the required fill weight from the control interface, for 20-liter containers and the other supported sizes.

2- Weighing and filling

During filling, the weighing system measures the product weight in real time and sends the data to the control system. As the weight approaches the target, the filling speed is reduced gradually so that the required weight is reached with high accuracy. Once the set weight is reached, the filling valve closes automatically.

3- Storing filling data

The machine can store the filling settings and parameters (such as fill weight and filling speed) for different products, so the operator can recall the required settings and switch quickly between products and filling programs.

Reliable performance, easy operation

The line is designed to combine high accuracy, flexibility and ease of operation, making it suitable for engine oil, lubricant and industrial liquid production lines that need precise, stable filling.
