Rotofill EVO – Semi-automatic rotary filling machine for liquids and creams
Rotofill EVO is a semi-automatic rotary filling machine with a trolley-mounted dosing group. It is designed to be agile and versatile: handling different products, quick format changeovers, and a wide volume range thanks to the trolley with dual dosing units. It suits multiple industries and different packaging types.
This model expands the Copack range by leveraging the know-how developed since 1996 (heritage of the former Dosapack, 1971–1996), experience that has guided the machine’s design and development.
Features of the Rotofill EVO filling machine
Rotofill EVO is composed of workstations managed from the HMI, each with dedicated parameters:
- Bottle infeed
Variable-speed conveyor to synchronize the flow with subsequent phases. - Dosing
Two nozzles height-adjustable from the HMI. It is possible to dose during the nozzle’s upward motion to handle foaming products without generating foam. - Cap placement
Manual station: the operator positions caps or pumps flexibly, supporting different packaging types; the “open” station facilitates the management of heterogeneous cap families. - Capping
Pneumatic stabilizing gripper; capping/screwdriving unit on a pneumatic slide with a brushless motor. Settings for speed and torque; interchangeable heads according to cap type and material. - Outfeed
Conveyor prepared for in-line integration with a labeler or an accumulation table.
Interface and adjustments
- 7″ HMI touchscreen for centralized management of working parameters.
- Remotely mounted pneumatic panel for efficient flow control.
- On-trolley pneumatic panel for product suction and dosing control.
Dosing units
The dosing units are pneumatic volumetric: the adjustment handwheel acts on the cylinder stroke, defining the dosed volume.
The two units are independent and mounted on a trolley external to the machine:
- Reduced downtime: at end of batch, connect the second ready unit and restart while the first one is disassembled and cleaned.
- Fast format changeover: manage two formats in parallel by mounting a small cylinder on one unit and a larger one on the other.
Available dosing-cylinder sizes:
- 1 to 20 mL
- 5 to 50 mL
- 30 to 260 mL
- 50 to 1100 mL
Operating mode
Rotofill EVO is designed to be run by two operators: the first maintains the bottle load on the infeed conveyor and manages finished bottles accumulated on the rotary table; the second places the cap on the bottle.
Strengths of the Rotofill EVO (why choose it)
- Liquid precision: the diving nozzle allows dosing during the nozzle’s ascent, giving greater control of the filling phase inside the bottle.
- Flexibility: simple changeovers, and the trolley with dual dosing units significantly reduces downtime.
- Closure quality: settable tightening torque; cap-dedicated heads.
- Options and accessories: the machine can mount several options and accessories to widen the range of products it can fill and cap.
Fields of application
Cosmetics, pharmaceuticals, food—filling glass or plastic bottles/vials or jars with liquid and creamy products (e.g., lotions, serums, solutions, light oils, creams, foundation, etc.).
Mini-FAQ
- Which products can it handle? Water-like, oily, and also medium/high-viscosity products, with the appropriate accessories and machine settings.
- How does the machine handle such a wide range? Thanks to the dosing trolley, replaceable parts for format changeovers, and available options: compatibility with packaging and products of different density/viscosity/volume.
- Can it be integrated in-line? Yes: prepared for labelers and downstream systems; synchronous conveyor management.
Optionals
The ROTOFILL EVO is also prepared to mount options and accessories that allow the machine to widen the range of products it can fill and cap.
- Dosing-cylinder changeover: precision across different volumes.
- PID temperature control: hopper heating for more viscous products.
- Anti-drip nozzle: prevents dripping at end of cycle.
- 16 L hopper: multiple hoppers for quick product/format changeovers.
- Suction tube: direct-from-tank dosing without passing through the hopper.
