Description

Single Head ROPP Screw Capping Machine is a specialized packaging machine designed for applying and sealing ROPP or screw caps onto bottles, typically used in industries such as pharmaceuticals, food and beverage, cosmetics, chemicals, and distilleries. The Single Head ROPP Screw Capping Machine is a compact, versatile, and efficient machine engineered to securely apply aluminum ROPP caps or plastic screw caps to containers, ensuring tamper-evident and airtight seals. It is suitable for low to medium production runs, with output speeds typically ranging from 35 to 50 bottles per minute, depending on bottle size, cap type, and machine configuration. The machine is precision-built with a sturdy welded frame, often enclosed in stainless steel with a matte finish for durability, corrosion resistance, and compliance with cGMP standards.

The Single Head ROPP Screw Capping Machine is an efficient, reliable, and versatile solution for small to medium-scale bottling operations. Its robust construction, user-friendly features, and compatibility with various industries make it a preferred choice for secure and tamper-evident bottle sealing. For higher production needs, multi-head or fully automated rotary cappers may be considered.

Primarily designed for lower to medium production volumes, making it less suitable for high-speed, large-scale operations compared to multi-head cappers.

Requires change parts for different bottle and cap sizes, which may add to setup time and cost.

Semi-automatic models rely on manual bottle handling, which may slow down production for larger runs.

Automatic Single Head ROPP Capping Machine: Fully automated with conveyor and cap feeder for continuous operation.

Semi-Automatic Single Head ROPP Capping Machine: Manually loaded bottles with motorized capping for smaller-scale operations.

Servo Torque Models: Use servo motors for precise torque control, adjustable via touch screen.

Working Principle of Single Head Ropp Screw Capping Machine

The filled bottles moving on conveyor belt and fed into an in feed star wheel by in-feed worm. While moving in feed star wheel, bottles pick up caps one by one from delivery chute. The descending rotary sealing heads hold bottle’s neck with desired pressure. The sealing is done in a programmed roll-on manner, accurate positioned of the caps is done mechanically by means of a rotating unscramble, to direct the caps correctly into the chute, when the chute is filled up the rotating unscramble drive is disengaged, hence, there is no chance to damage of caps. The sealing roller takes place due to rotating sealing head and transfer movement of sealing & threading rollers due to sealing cam. The sealed bottles are discharged by exist star wheel on conveyors.

Bottle and Cap Feeding:
- Bottles are fed into the machine via an infeed conveyor and aligned using a star wheel or positioning plate to ensure precise placement under the capping heads.

- Caps are sorted and oriented by a cap feeder and placed onto the bottle neck via a cap chute.

Capping Process:

- The capping head, equipped with threading and sealing rollers, descends onto the bottle and applies downward pressure to press the unthreaded aluminum cap onto the bottle neck.
- Rollers crimp the cap, forming threads that match the bottle’s neck and creating a tamper-evident seal with a pilfer-proof band.
- Torque is precisely controlled to ensure a secure seal without damaging the cap or bottle.

Output:

- Sealed bottles are transferred to an outgoing conveyor for further processing.
- Quality control systems, such as defect rejection mechanisms, verify proper cap placement and sealing.

Applications of Capping and Sealing Machine

Advantages of Single Head Ropp Screw Capping Machine

Tamper-Evident Sealing: ROPP caps provide a pilfer-proof seal, enhancing product security.

Versatility: Handles various bottle and cap sizes with quick changeover times.

Durability: Aluminum ROPP caps resist moisture, temperature, and light, protecting sensitive products.

Efficiency: Automated models increase production speed and reduce manual labor.

Compact Design: Ideal for facilities with limited space.

Key Components of Single Head Ropp Screw Capping Machine

Construction and Materials:
- Built on a robust mild steel or stainless steel frame, fully enclosed in stainless steel cladding or sheets for easy maintenance and hygiene.
- Contact parts are made of high-quality materials like stainless steel, aluminum, Delrin, or silicon to ensure durability and compliance with industry standards.

Operation:
- Automatic Models: Bottles are fed via a conveyor belt into a star wheel, which positions each bottle under the single capping head. The bottle picks up a cap from a delivery chute or cap feeding bowl. The capping head rotates and descends to thread and seal the cap onto the bottle neck, ensuring a secure, tamper-evident closure. After sealing, the bottle is transferred to the outfeed conveyor for further processing.
- Semi-Automatic Models: Bottles are manually placed under the capping head, which is activated by dual control buttons or a motorized mechanism. The head descends, rotates, and seals the cap, after which the bottle is manually removed. This is ideal for smaller production runs.
- Features a “No Container, No Cap” system to prevent cap wastage and ensure efficient operation.

Cap and Container Compatibility:
- Suitable for a variety of container shapes and materialswith minimal change parts required.
- Handles ROPP caps and screw caps with adjustable sealing pressure to accommodate different cap sizes and gauges.
- Capable of sealing bottles ranging from small vials to larger containers.

Automation and Control:
- Equipped with a single motor that synchronizes the conveyor, star wheel, platform turret, and capping head for seamless operation.
- Features like PLC control, HMI touch screen, and inverter-controlled speed variation allow precise adjustments and user-friendly operation.
- Includes safety features such as a safety clutch, emergency stop button, and automatic stop sensors.

Additional Features:
- Adjustable conveyor height to align with other production line equipment.
- Low noise levels and power consumption for cost-effective operation.
- Optional cap feeding systems, such as vibratory feeders, mechanical orientators, or waterfall-type elevators, for continuous cap supply.
- Some models include acrylic or toughened glass safety cabinets for operator safety.
