Cap Elevator & Orienter
Here are the detailed specifications and descriptions for a Cap Elevator and Cap Orienter, which are essential components in automatic bottle capping lines. These systems ensure continuous feeding and correct orientation of caps before capping.
🧱 1. Cap Elevator – Specification
A Cap Elevator is used to transport caps from a hopper (ground level) to a cap orienter or sorter at a higher elevation. Ideal for feeding caps into rotary or inline capping machines automatically.
Feature | Specification |
Function | Lifts caps from bulk hopper to sorting/orienting unit |
Speed | Adjustable (up to 300 caps/min or more depending on cap size) |
Cap Type | Plastic screw caps, flip-top caps, press-fit caps (varies with design) |
Cap Size | Diameter: 20–70 mm (customizable) |
Belt Type | Cleated (PU or PVC) belt with side guides |
Capacity | Hopper: 50–200 liters (or more, based on design) |
Material | SS304 body with food-grade PU belt |
Height | Customizable to match capper height (typically 1.5–2 meters) |
Motor Type | Geared motor with speed control (variable frequency drive – VFD) |
Sensors | Level sensor to auto-start/stop based on capper demand |
Power Requirement | 0.5 – 1.5 kW |
Noise Level | < 70 dB |
Footprint | Compact, mobile design (wheels optional) |
🌀 2. Cap Orienter – Specification
A Cap Orienter ensures that the caps are correctly aligned (open side down, logo forward, etc.) before being delivered to the capping head.
🔹 Rotary Disc or Centrifugal Orienter (Most Common)
Feature | Specification |
Function | Aligns caps using centrifugal force and mechanical guides |
Speed | Up to 300 caps/min (higher with custom design) |
Cap Compatibility | Round, oval, flip-top, childproof, etc. (custom guides) |
Disc Size | 400–800 mm diameter |
Orientation Accuracy | > 98% |
Cap Sorting | By gravity track, air jet, or mechanical rejectors |
Material | SS304 and anodized aluminum |
Sensors | Jam detection, low cap level, orientation sensor |
Integration | Mounts above the capping turret or on a separate stand |
Power | 0.5 – 1.5 kW |
Control | Manual or PLC integrated |
Special Features | Can include anti-static units for high-speed lines |
🔸 Other Types
- Vibratory Bowl Orienters – used for small caps in pharma or cosmetics
- Air Sorting Channels – for lightweight, small-diameter caps
🔄 Cap Elevator + Orienter System: Combined Workflow
- Cap Elevator feeds loose caps from ground-level hopper.
- Caps travel up via cleated belt.
- Caps are dropped into the orienter.
- Orienter aligns caps correctly and feeds them into the cap chute.
- Caps are delivered to the capping machine chute in the correct position.
✅ Optional Features
- Dust cover or acrylic enclosure
- Hopper vibration for smooth feeding
- Auto cap level sensor and refill alarm
- Multiple cap size compatibility (with tool-less changeover)
📦 Applications
- Beverages (PET bottle screw caps)
- Pharmaceuticals (CRC – child-resistant caps)
- Personal care (flip-top and snap caps)
- Food & dairy (wide-mouth closures)
