# Industrial Specification: Rotary Capping Head

## 1. Technical Definition
A precision mechanical component that applies and tightens caps onto bottles in a rotary capping machine.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 NÂ·m torque at 60-120 RPM rotational speed**. Failure boundary: **3.0 NÂ·m torque causing permanent deformation of the cam follower mechanism**, Mechanism: **Plastic deformation of the cam follower due to Hertzian contact stress exceeding the yield strength of 17-4PH stainless steel (1100 MPa)**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.

| Symbol | Variable Definition | Localized Reference |

| C | Dynamic Load Rating | Engineering Constant |
| P | Equivalent Dynamic Load | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.05 mm between the capping head spindle and bottle neck axis | 8 | Eccentric loading causing premature bearing wear and torque transmission loss | Integrate laser alignment sensors with real-time feedback to the servo positioning system |
| Cap thread mismatch with bottle neck threads (pitch deviation &gt; 0.1 mm) | 8 | Cross-threading leading to torque overload and clutch slippage | Implement machine vision system with convolutional neural network to verify cap-bottle thread compatibility before engagement |

- **Caution**: 

### Q: What materials are used in the rotary capping head construction?
**A**: The rotary capping head is constructed from durable materials including stainless steel for corrosion resistance, alloy steel for strength, and engineering plastics for lightweight components, ensuring longevity and reliability in industrial environments.

### Q: How does the torque clutch or servo drive function in the capping head?
**A**: The torque clutch or servo drive provides precise torque control during cap tightening, preventing over-tightening or under-tightening. This ensures consistent seal integrity and reduces product waste in high-speed bottling operations.

### Q: Can the rotary capping head be adjusted for different bottle sizes?
**A**: Yes, the height adjustment mechanism allows for quick adaptation to various bottle heights, while interchangeable chuck/gripper jaws accommodate different cap diameters, making it versatile for multiple production lines.
