Six Head Ropp Screw Capping Machine

Key Features and Description:

1. Construction and Design:

   • Material: Built with a sturdy welded mild steel (MS) or stainless steel (AISI 304) frame, fully enclosed in stainless steel sheets with doors for easy maintenance. The matt-finished body ensures durability, corrosion resistance, and compliance with hygiene standards like cGMP.

   • Adjustable Height: Features a height-adjustable system to accommodate various bottle sizes and shapes with minimal changeover parts.

   • Compact and Versatile: Designed for seamless integration into existing production lines, with a modular structure for quick setup and operation.

2. Operation:

   • Capping Mechanism: Equipped with six rotary capping heads that pick, place, and seal caps onto containers. The machine uses a combination of rollers to ensure precise threading and tamper-proof sealing.

   • Cap Feeding: Includes an orientation-type cap feeder or vibratory bowl feeder to automatically align and deliver caps to the capping heads, ensuring continuous operation. Optional waterfall-type elevators or mechanical cap feeders can be integrated for high-volume cap storage.

   • Bottle Handling: Bottles are fed via a conveyor belt, spaced by an infeed worm, and positioned under capping heads using a star wheel system. The “No Bottle, No Cap” feature prevents cap wastage and ensures operational efficiency.

   • Torque Control: Adjustable torque settings allow customization for different cap sizes and materials, minimizing cap damage and ensuring secure sealing.

3. Performance:

   • Output Capacity: Capable of sealing 4,800 to 6,000 bottles per hour, depending on bottle size, cap type, and configuration. Some models can achieve up to 12,000 bottles per hour with optimized settings.

   • Bottle Compatibility: Suitable for glass, plastic, PET, HDPE, or LDPE bottles with diameters ranging from 22 mm to 100 mm and cap sizes from 18 mm to 38 mm.

   • Sealing Precision: Incorporates a “No Cap, No Roll” safety feature and spring-loaded rollers to prevent damage to caps or bottles and accommodate variations in neck diameter.

4. Additional Features:

   • Safety Features: Includes safety clutches on the star wheel and feed worm to stop the machine in case of jamming or overturned bottles. A background suppression sensor may also halt operation if no caps are detected in the chute.

   • Low Maintenance: Self-lubricating UHMW-PE guide profiles reduce friction and wear, ensuring smooth, noiseless operation and minimal downtime.

   • Optional Add-Ons: PLC with Human Machine Interface (HMI), laminar airflow for class 100 applications, digital bottle counter, and cap elevators for enhanced automation.

   • Noise and Power Efficiency: Operates at low noise levels and consumes minimal power, making it suitable for extended production runs.

5. Applications:

   • Ideal for sealing bottles in industries such as:

     • Pharmaceuticals: Syrups, oral liquids, and vials.

     • Food and Beverages: Juices, edible oils, and sauces.

     • Cosmetics: Shampoos, lotions, and creams.

     • Chemicals and Pesticides: Liquid chemicals and agrochemicals.

     • Distilleries: Wine, spirits, and liquors.

6. Advantages:

   • High-Speed Operation: Boosts production efficiency with consistent, high-quality sealing.

   • Tamper-Proof Sealing: ROPP caps provide security and evidence of tampering, critical for pharmaceuticals and food safety.

   • Versatility: Handles a wide range of bottle and cap types with quick changeovers, reducing downtime.

   • Durability: Stainless steel construction ensures long-term reliability and compliance with hygiene standards.

Working Principle:

• Bottles are fed from a filling machine or unscrambler onto a stainless steel slat conveyor.

• An infeed worm ensures proper spacing, and a star wheel positions bottles under the six capping heads.

• Caps are oriented and delivered via a vibratory bowl or cap feeder to the capping heads.

• Each capping head picks a cap, aligns it with the bottle, and uses rollers to thread and seal it securely.

• Sealed bottles are transferred via an exit star wheel to the next process.
