Technical details and manufacturing context for Capping/Crowning Machine

Definition

The Capping/Crowning Machine is a component used in beverage manufacturing, specifically in carbonated soft drink production lines. Its primary function is to place and seal metal crowns or plastic caps onto filled bottles, ensuring an airtight closure that preserves carbonation, maintains product freshness, and prevents contamination during storage and transportation. The machine operates by receiving filled bottles from the filling station, positioning caps or crowns onto the bottle openings, and applying controlled pressure to crimp metal crowns or screw plastic caps, creating a secure seal. Key parameters include a capping speed of 6000–24000 bottles per hour (bph), with higher speeds requiring a larger capping turret and infeed timing. It accommodates bottle diameters of 50–110 mm and heights of 150–320 mm, with change parts needed outside these ranges. Capping torque ranges from 1.5 to 5.0 N·m, critical for seal integrity; too low causes leaks, too high damages the cap. Capping accuracy is ±0.2 mm to ensure alignment and consistent sealing. Operating pressure is 0.6–0.8 MPa (ISO 8573-1 reference), below 0.6 MPa insufficient force. Power supply is 380 V AC ±10%, three-phase, 50/60 Hz (IEC 60038 reference), with installed power of 5.5–15 kW depending on capping heads and bottle size. Operating temperature is 5–45°C, relative humidity 30–85% non-condensing. Ingress protection is IP54–IP65 (IEC 60529 reference), with IP65 for washdown environments. Machine weight is 1500–3500 kg, and footprint is 2000×1200×2200 mm (L×W×H). Materials include stainless steel, food-grade plastics, and aluminum alloys. Verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The machine receives filled bottles from the filling station via an infeed conveyor. Bottles are indexed into the capping turret, where caps or crowns are fed from a hopper and positioned onto each bottle opening. For metal crowns, a crimping head applies radial pressure to deform the crown edges around the bottle rim. For plastic caps, a spindle applies downward force and rotational torque to thread the cap onto the bottle neck. The capping torque is precisely controlled within 1.5–5.0 N·m to ensure a tight seal without damaging the cap or bottle. After capping, bottles are discharged to the outfeed conveyor for downstream processing. The machine's speed, typically 6000–24000 bph, is synchronized with the filler and other line equipment. Height adjustment is motorized to accommodate bottle heights from 150–320 mm. The system operates on compressed air at 0.6–0.8 MPa and electrical power of 380 V AC. Sensors monitor cap presence, alignment, and torque, providing feedback for quality control. The machine is designed for continuous operation in beverage plants, with stainless steel and food-grade materials for hygiene.

Frequently Asked Questions

What bottle sizes can this capping machine handle?

The machine handles bottle diameters from 50 to 110 mm and heights from 150 to 320 mm. Outside these ranges, change parts are required. Always confirm compatibility with the manufacturer for specific bottle designs.

What is the typical capping speed range?

The capping speed ranges from 6000 to 24000 bottles per hour (bph). Higher speeds may require a larger capping turret and precise infeed timing. The actual achievable speed depends on bottle size, cap type, and line configuration.

How is capping torque controlled?

Capping torque is adjustable within 1.5 to 5.0 N·m. It is critical for seal integrity: too low torque can cause leaks, while too high can damage the cap or bottle. The machine uses controlled pressure and spindle speed to achieve the set torque.

What are the utility requirements?

The machine requires a three-phase power supply of 380 V AC ±10% (50/60 Hz) and compressed air at 0.6–0.8 MPa. Installed power is 5.5–15 kW depending on configuration. Operating temperature should be 5–45°C and relative humidity 30–85% non-condensing.
