Automated Beer Canning Line (12-1 Isobaric Filler & Seamer) - 800-1,200 CPH

Main Features

• Integrated Filler-Seamer Design: The filling and sealing systems are designed as a single, unified unit. The seamer's power system drives the filler, ensuring absolute synchronization and coordination between the two critical processes.

• High-Precision Isobaric Filling: The line employs an equal-pressure filling principle with high-precision mechanical valves. This results in fast filling speeds, accurate liquid levels, and incorporates a "no can, no fill" safety feature to prevent waste.

• Advanced Automation & Control: It utilizes the world's most advanced mechanical, electrical, and pneumatic control technologies. The system is built with premium components, including PLC, frequency converters, and proximity switches from brands like Schneider and Omron, ensuring stable and reliable performance.

• Stable Can Handling: The line uses a bottom-up conveying method, which provides superior stability for cans throughout the entire process. A pre-cover device and can bottom support structure ensure maximum stability as cans enter and exit the filling machine.

• Hygienic & Adjustable Design: The filling valve and material tank manufacturing processes have been improved to ensure filling accuracy and fully comply with the beverage industry's hygiene requirements. The filling tank height is adjustable via a worm gear box to accommodate cans of different specifications.

• Superior Sealing Technology: The seaming machine incorporates proven Taiwanese capper roller and pressure head technology to guarantee a high-quality, reliable double-crimp seal. It includes a "no can, no lid" control system to reduce lid waste and ensure smooth operation.

Working Principle

1. Filling Station

Empty cans are fed from the conveyor and separated by a timing screw. They are transferred via a star wheel to the 12 filling heads.

1. Lifting & Sealing: A pneumatic cylinder lifts the can, pressing it against the filling valve's conical sealing gasket.

2. Counter-Pressurization: A cylinder opens the valve, first inflating the can with CO2 to equalize the pressure with the main beer tank.

3. Filling: Beer flows gently from the main tank into the can. The filling process automatically stops when the rising liquid level blocks the air return port.

4. Pressure Release: A foam discharge valve slowly vents the pressure.

5. Transfer: The support cylinder lowers the filled can, which is then transferred by a synchronized hook chain to the seaming station.

2. Sealing Station

1. Lid Dispensing: Lids are manually loaded into a chute (capacity ~200 lids). When a can is detected, a cylinder activates a splitting knife, dropping a single lid onto the can.

2. Seaming Process: The can support plate lifts the can, pressing the lid tightly against the rotating pressure head. The can, lid, and plate spin together at high speed. Under the action of the sealing cam, the seaming roller performs the first and second sealing operations (double crimp).

3. Discharge: The perfectly sealed can is pushed out by the capping mechanism head and transferred to the exit conveyor belt.

Technical Parameters

Electrical Control

The machine is powered by an AC 380V three-phase, four-wire supply. The main motor uses a frequency converter for stepless speed regulation.

• High-Quality Components: The electrical system is designed by senior engineers and features a Japanese Mitsubishi PLC, frequency converter, and proximity switches, a German Siemens analog output, and Korean solenoid valves.

• Touch Screen HMI: The entire production speed can be set as required on the user-friendly touch screen. All common faults trigger an automatic alarm and display the fault's cause and location.

• Intelligent PLC Control: Based on the severity of a fault, the PLC automatically determines whether the machine can continue to run or must be stopped, ensuring stable and reliable performance.
