Glass automatic loader

gantry

General description
Industrial belt cold-top batch chargers designed for modern electric glass furnaces. Two main configurations are available to suit furnace geometry: XY type for rectangular/square furnaces and RADIAL type for hexagonal, dodecagonal or other non-rectilinear sections. The system ensures uniform batch distribution and integrates measurement and safety systems for automated dosing and operator protection.

Types

• XY TYPE: bi-axial X–Y movement for square or rectangular furnace layouts.
• RADIAL TYPE: rotational/oscillating boom movement for circular, hexagonal or multi-sided furnace geometries.

Key machine features

• Uniform feeding across the furnace surface to optimize melting and energy use.
• Applicable to electric glass furnaces with production capacities from 4 to 250 tons/day.
• Adjustable charging capacity with belt speed modulation controlled by glass level measurement.
• PLC-based control system with dedicated dosing software that divides the furnace into zones for dynamic batch distribution.
• Advanced safety architecture using multiple laser scanners and PLC safety levels for perimeter protection.
• Load-cell weighed hopper for precise feed flow control and batching accuracy.
• Emergency manual handling available via rapid pneumatic motor disengagement for blackout situations.

X-Y type - Machine components

• Main metallic gantry translating on the X axis via rails.
• Motorized traversing boom with Y-axis sliding for precise placement.
• Triple-layer conveyor belt for bulk raw material transport.
• Pyramid dosing hopper mounted on the main structure with load cells for weight control.

Radial type - Machine components

• Main metallic structure with rotational/oscillating motion for radial coverage.
• Motorized boom for dosing and distribution.
• Triple-layer conveyor belt for raw material feed.

Mobility and control
Both configurations offer high mobility and are managed via PLC. Proprietary software segments the furnace surface into zones and continuously adjusts deposited batch quantities, preventing overloads or uncovered areas and optimizing melting performance, especially near electrodes.

Safety and maintenance features
Three laser scanners generate a dynamic protection field adapting to boom position; the safety radius reduces when the boom is retracted to permit maintenance access. A traversing frame and rapid motor disengagement system enable quick removal and safe manual intervention, minimizing downtime.

Additional safety items and controls

• Laser perimeter safety monitoring.
• Laser monitoring of boom movement and lateral position.
• Boom rollover protection system.
