Weighing Filling Machine For Liquid

Weighing filling machines are supplied in both automatic and semi-automatic configurations. Semi-automatic weighing filling machines feature one or two fill heads. During semi-automatic operation, the operator places containers under each fill head. A button is pressed to initiate fill, and fill stops when the targeted weight is reached. The operator removes the filled containers, and the process begins again.

Automatic weight fillers are used to achieve faster container rates and reduced operator intervention. Available in one, two, three, four, six, and eight-head configurations, automatic fillers index containers under the fill heads from an upstream queue. The fill cycle starts and stops automatically, and new containers move under the fill heads as full containers proceed downstream.

VKPAK has provided its customers with a variety of weighing filling machines below 10L, including semi-automatic and fully automatic, as well as filling equipment for containers of various shapes.

When delivering products to a filler, it is important to ensure that they are distributed equally among all fill heads. The most commonly used method is manifold fill, which involves a main supply and branch lines that split the flow to each individual fill head. Due to the pressure from the supply pump, it is necessary to include three valves and a nozzle in each branch. The shut-off valve controls the flow to the fill head, and can be open or closed depending on whether filling is required. The dribble valve, which also has two positions, allows for the rapid fill cycle when open and partially restricts flow for the dribble cycle when partially closed. This valve can be adjusted to vary flow rates and control the accuracy of the filler. The balancing valve is used to ensure that the product is delivered to each fill head at an equal rate, and is typically a manual valve that requires adjustment during startup.

The pressure over product (POP) system shares many of the same benefits as the direct fill system, including a single product delivery valve and adjustments for flow, balance, and dribble at the nozzles. However, instead of utilizing head pressure, the POP uses a closed, pressurized reservoir to control product flow across multiple filling heads. Higher pressure delivery extends the effective viscosity range. The external nozzles introduce additional cleaning requirements but offer easier changeout and flexibility.

As an expert in the liquid weighing filling industry, VKPAK can attest to the critical role that product supply plays in the successful operation of a filler. Various methods, such as gravity, pumps, and hydraulic presses, can be used to deliver the product to the filler, depending on the specific requirements of the system.

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.

In the liquid weighing filling industry, two primary conveying options are available for in-line fillers. The single straight-through conveyor design is commonly used for semi-automatic fillers and smaller automatic fillers, transporting containers to and from the fill heads. However, for larger automatic lines such as the six- and eight-head fillers, as well as certain four-head fillers, the time required to convey the first container past all the fill heads to the final position may be excessive.

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.

In the liquid weighing filling industry, fill rate and containers per minute are key considerations for filling lines. However, achieving a high fill rate is impacted by several variables, including proper nozzle selection, establishing a dribble weight, and increasing conveyor speed. Product viscosity is also a crucial factor, as thin products may splash or foam and spill from containers when filled close to the top, while more viscous products may allow for quicker filling and transport. Understanding the product viscosities, container sizes, container types, and fill levels is therefore essential.

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.
