Overflow – Level Linear Liquid Filling Machines

Overflow liquid filling machine is best suitable for liquids from low to medium viscosity, and also ideally used to fill very foamy products at high speed. Overflow liquid filling machines are used to produce a cosmetic fill level, making them ideal for filling transparent containers that require a consistent fill level. Overflow liquid filling machines are also the best choice for filling products where the internal volume of a container may vary slightly, such as glass bottles.

The Konek Technology automatic linear overflow filler is manufactured with a 304 quality stainless steel frame. Our overflow filling machines are based on heavy-duty stainless steel frames with all contact parts made of food grade materials, they deliver precision dose filling, and have flexible filling options. The unit consists of a stable basic frame, completely closed, with removable stainless steel sheathing.

Explosion proof versions of this machine are suitable to handle all those products classified as potentially Hazardous and can be supplied and certified in full compliance with European Standards. Additional options are available for sanitary, hazardous, flammable and corrosive environments.

Containers are conveyed into the filling area. When the correct amount of containers have entered the machine, the conveyor stops. The spout bar then descends, sealing the nozzles against the container openings. The desired product to be filled is held in a stainless steel reservoir, then pumped into a manifold to disperse product to each of your filling nozzles. Once the product reaches your desired cosmetic fill level in each bottle, excess product or foam overflows back to the reservoir. The filling cycle is completed based upon time factors programmed into the PLC. When the fill cycle is complete, the head is raised, triggering the conveyor to restart. Either gravity, pressure, vacuum, or combination filling systems can be utilized. The servo system is used for height and width adjustments, and changeover can easily be done on the HMI.

The machine comes standard with a touch screen panel which allows operator to have simple and quick setup by storing and recalling product recipes. The personalized control panel system provides users an easy operation experience and an effective management through production monitoring on the PLC. Error messages are instantly shown on the touch panel which features ease of the machine maintenance and troubleshooting.

Konek Technology automatic pressure overflow liquid filler is typically used in consumer packaging applications where a consistent visual (cosmetic) fill level is required. Applicable products include cosmetics, chemicals, sauces, syrups, light gels and shampoos, foamy cleansers, food and beverages and much more.
