Bottle Holding Fixtures

Bottle holding fixtures are precision components used in rotary carousel systems within beverage manufacturing. Their primary function is to secure bottles in a stable, fixed position as the carousel rotates through various processing stations, such as filling, capping, labeling, or inspection. These fixtures prevent bottles from shifting, tipping, or misaligning, which is critical for maintaining product quality and operational efficiency. The fixtures are designed to accommodate a range of bottle sizes, with a standard bottle diameter range of 50–120 mm and a height range of 100–350 mm. They provide a holding force of 50–200 N to ensure a secure grip during high-speed rotation, and achieve a positioning accuracy of ±0.05 mm, which is essential for precise filling and capping alignment. The operating pressure range is 1.0–1.6 MPa, and the operating temperature range is -10 to 60°C for standard rubber seals, with higher temperature options available. The fixtures offer ingress protection rated IP54–IP65, protecting against dust and water jets. Materials on file include stainless steel (grades 304/316 per ASTM A240) and food-grade plastic. The stainless steel provides corrosion resistance, while the food-grade plastic is suitable for direct contact with beverage products. The fixtures weigh between 0.5 and 2.0 kg, designed to be lightweight for high-speed rotation. Surface roughness is maintained at Ra 0.8–1.6 μm to prevent bottle damage. The expected cycle life is 5–10 million cycles, depending on maintenance and operating conditions. These fixtures are typically used in automated beverage production lines where consistent bottle positioning is required. They are available in standard sizes, with custom sizes available upon request. It is important to verify model-specific values and standards with the legal manufacturer or supplier, as the parameters listed are reference ranges and may vary for specific applications.

The fixtures use mechanical clamping, spring-loaded mechanisms, or custom-shaped cavities to grip bottles securely. As the rotary carousel rotates, these fixtures maintain consistent bottle positioning, allowing automated equipment to perform operations with precision and reliability. The holding force is adjustable to accommodate different bottle sizes and weights, ensuring a secure grip without damaging the bottle surface. The design minimizes vibration and movement, which is critical for high-speed operations.
