Brictec Double-Stack Firing Line with Automatic Pallet Handling System
Overview
The Double-Stack Firing System represents the core of modern, high-end clay brick and block production. It is the key automation equipment for producing premium wall materials with precise forming, stable drying, and uniform firing. Among all subsystems, the Automatic Pallet Handling System plays a vital role, enabling continuous, efficient, and intelligent circulation of green and dried bricks between drying and firing stages.
This system integrates advanced PLC automation, servo motion control, and modular mechanical design, ensuring smooth operation, consistent quality, and high productivity.
System Composition
The complete system includes multiple coordinated modules:
- Clay Strip Cutting System - servo-driven for precise, vibration-free cutting
- Brick Cutting System - dual-frame configuration with automatic wire-change and optional chamfering
- Green Brick Grouping and Loading System - automatic defect detection and waste brick removal
- Automatic Pallet Loading System - accurately places wet bricks on moving pallets
- Pallet Transfer System - moves loaded pallets toward the drying area via conveyor lines
- Pallet Storage & Buffering System - temporarily stores loaded pallets in sequence
- Pallet Lifting & Shelving System (Upper & Lower Racks) - the core of this design, enabling automatic vertical lifting and placement of pallets into the single-layer tunnel dryer
- Pallet Unloading System - removes dried pallets and transfers them for unloading
- Dry Brick Grouping and Pallet Unloading System - prepares bricks for secondary stacking onto kiln cars
- Automatic Stacking System (Kiln Car Loading) - arranges dry bricks according to the required firing pattern
All units are linked via the PROFIBUS field bus network, controlled through a central PLC, and supervised by an industrial PC for real-time monitoring, parameter adjustment, and production data management.
Core: Pallet Lifting and Shelving System
The automatic pallet lifting system is designed to transfer wet pallets into the tunnel dryer shelves efficiently and safely, retrieve dried pallets and send them to the unloading station automatically, and operate in continuous cycles to ensure uninterrupted drying-firing flow.
Technical Highlights
- Servo-Controlled Lifting: Ensures smooth motion and precise positioning
- Dual-Column Elevators: Provide structural stability and safety redundancy
- Automatic Rack Alignment: Optical sensors ensure accurate docking with shelf positions
- Pallet Tracking System: Monitors pallet ID, position, and drying status in real-time
- High-Speed Exchange Cycle: Supports simultaneous loading/unloading for minimal idle time
This system eliminates manual pallet handling, significantly improving safety, accuracy, and production efficiency.
