Weigh filling machines, also known as net weight filling machines, are packaging machines that use scales to measure the exact amount of product dispensed into the container (VKPAK mainly offers weigh filling equipment for liquids). They are best for liquids filled in bulk quantities, such as 5-gallon pails, or products that have a very high value and thus need to be weighed correctly to avoid losing profit. Weigh filling machines are ideal filling solution due to their ease of automation, flexibility to handle multiple container sizes and varying product densities, and ability to maintain accuracy even with products containing entrapped air.View Video

How Does A Net Weight Filler Work?
Understanding Weighing Filling Machine Product Delivery , Product Supply, Conveying Options And Filler Performance
For Direct Fill System (DFS) and Pressure Over Product (POP) delivery, maintaining consistent flow is less of a concern, as compared to manifold systems where consistent flow is crucial for optimal operation.
Gravity is the simplest means of supplying the filler, as it requires minimal equipment and can be easily controlled by closing a valve. However, the drawback of this method is that flow rates will vary during the filling cycle as the level in the supply tank reduces. This issue does not apply to DFS fillers, as flow rates are determined by the reservoir level, not feed pressure.
Air-operated double-diaphragm pumps (AODDs) are a cost-effective method of supplying a filler. However, surges from AODDs must be reduced when supplying a manifold system, and a pulsation dampener should be installed in such cases. To ensure effective operation, a valve must be installed immediately after the pulsation dampener to introduce backpressure. While the supply can be dead-headed, the filler will shut off air pressure to the pump to reduce backpressure and eliminate splatter when valves are opened. For DFS and POP systems, pulsation dampeners are not necessary.
Positive displacement pumps deliver a consistent flow to the filler, but they cannot be dead-headed. Therefore, it is recommended to include a recirculation line to avoid excessive wear and tear on the electric motors and address safety concerns. When flow to the filler stops, the pump can be stopped, and excess pressure is relieved through the recirculation line.
For non-free-flowing products, a hydraulic ram press can be used. This press uses hydraulic pressure to force a platen down into the supply tank, pressing the material out of the discharge valve and into the filler. To ensure optimal operation, the press should include a variable displacement hydraulic unit that allows the press to react to increased pressure during dribble and dead-head when the supply valve is shut.
To address this issue, a lateral transfer conveyor is implemented to reduce conveyor time for larger automatic lines. The lateral transfer conveyor consists of two parallel conveyors with the fill heads positioned in between. Containers are staged on the in-feed conveyor behind each fill head, and once full, all containers are transferred together onto the discharge conveyor. At the same time, the staged conveyors are moved under the fill heads, ready for the next cycle.
To prevent material from “sloshing” out of the container when accelerating from a full stop under the fill head to line speed, a variable-speed conveyor is employed. This feature is especially critical for open-top containers with low-viscosity materials and high fill levels, but sloshing can occur in any container with any type of material. The ability to adjust line speeds helps to ensure precise and accurate filling operations, enhancing the overall quality of the final product.
During the filling cycle, additional time-consuming operations can occur, which may impact performance. For automatic machines, the container must be isolated from vibrations caused by the moving conveyor, typically by lifting the scale to raise the container off the conveyor. In sub-surface filling, time is consumed as the lance travels to the bottom of the empty container and is removed from the filled container.
Delays may also be necessary before and after filling. Pre-fill, a slight delay may be imposed to ensure that the container is in place before opening the fill nozzle. Post-fill, delays may be required to allow the last of the product to drip from the nozzle or to get a final check-weight. Together with conveying, these non-filling operations can account for 40-70% of the total fill time.
While these operations may only represent a fraction of a second each, they can have a significant impact on performance. It is important to optimize each operation for maximum efficiency and accuracy. By understanding and carefully managing the variables and operations involved in the filling process, a high fill rate can be achieved while maintaining consistent accuracy and minimizing waste.
