I. Project Overview
Project Title: Liquid Level Inspection System
Project Purpose: Designed to detect liquid levels in products and automatically reject nonconforming items during online production.
Maximum Throughput: Up to 72,000 bottles/cans per hour (high-performance configuration).
Compatible Container Materials: Aluminum, tinplate, PE/PET/PP plastics, ceramics, glass, and other common packaging types.
Applicable Product Range: Volume 200–2000 ml; diameter 30–90 mm; height 50–200 mm.
Equipment Model: MT-HFX-06.
II. Environmental Conditions
Operating Altitude: 5–3000 meters above sea level.
Recommended Ambient Temperature: 5°C–40°C.
Relative Humidity Range: 50%–65% RH.
Factory Requirements: The plant’s floor flatness, load-bearing capacity, and other conditions must comply with national standards to ensure proper equipment operation.
Storage Requirements: Upon delivery to the factory, equipment and components must be stored in compliance with relevant national standards. During storage, appropriate lubrication and maintenance should be carried out to avoid surface damage or deformation that could affect installation, commissioning, and operation.
III. Production Requirements
Power Supply: 220V, 50Hz, single-phase (customer provided). Special voltage requirements must be communicated in advance, as they may affect equipment specifications, delivery schedule, and pricing.
Total Power Consumption: Approx. 1.0 kW.
Control Voltage: 24VDC.
Compressed Air: 4–12 Pa. The customer must provide the pipeline connection from the main air source to the equipment.
IV. Equipment Overview
1. Installation Plan
Positioning: Installed after the filling machine and before or after the inkjet printer.
Requirements: Must be placed on a single-row conveyor line, with at least 2 meters of straight-line conveyor space available.
Installation Timeframe: Full installation and setup can be completed within 24 hours.
Track Modification: A guardrail gap ≤15 cm should be cut into the straight conveyor to allow defective containers to be ejected.
Core Components: Inspection module, rejection unit, power distribution cabinet, HMI (human–machine interface), electronic components, and mechanical assemblies.
Rejected Product Collection: The purchaser is advised to prepare a rigid container for collecting rejected products at the designated ejection point.
2. Inspection Functions
High liquid level detection (auxiliary).
Low liquid level detection (standard).
3. Detection Principle
The system applies X-ray penetration technology. Containers with varying liquid levels produce distinct projection patterns on the receiving end, which are analyzed and displayed as different values. By comparing results against preset user-defined standards, the system identifies defective products. Nonconforming items are then automatically rejected from the line.
4. Equipment Features
Non-contact, online detection without damaging containers.
Defective container tracking by encoder ensures rejection accuracy is unaffected by line stops or speed fluctuations.
Automatically adjusts to different production line speeds for continuous, real-time inspection.
Independent inspection and control cabinets minimize electromagnetic interference, ensuring stable operation.
Stainless steel housing with sealed design provides resistance to condensation, fog, and water droplets, offering excellent environmental adaptability.
Automatic X-ray shutdown when idle for safety and energy efficiency.
Combination of hardware circuitry and embedded OS ensures long-term stability.
Integrated sound and light alarm system with automatic defective product rejection.
