Flat Belt Conveyor

Simple SummaryContent extracted from patent full text and abstract with AI.

The invention is a cover belt conveyor (Deckbandförderer) system designed to transport bulk goods, particularly up steep or vertical inclines, such as in mining or tunneling. It uses two continuous belts—one support and one cover belt—which run parallel and clamp the material between them for upward or downward movement. The unique feature is the integration of powered cylindrical rollers (side and middle rollers) that apply controlled pressure to the belts and are actively driven to transmit traction, enabling the conveyor to overcome greater vertical heights than previously possible. Its control system uses sensors and regulated actuators to optimize pressure, speed, and force, making the system more efficient, intelligent, and flexible.

Use CasesContent extracted from patent full text and abstract with AI.

• Vertical and steep bulk material transport in mining operations (e.g., ore or coal extraction shafts).
• Material handling in tunnel construction, transporting excavated debris upward out of the tunnel.
• Bulk cargo movement in ports or large industrial plants where space savings with steep conveyors is critical.
• Transport of sticky or difficult materials that require continuous, clean, and enclosed conveying.
• Use in underground mining or urban underground construction to move materials vertically with minimal handover points.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables much greater conveying heights and steepness than traditional bulk material conveyors without multiple transfer points.
• Facilitates reliable, continuous upward or downward transportation of even sticky materials, reducing maintenance and cleanup.
• Adjustable and electronically controlled pressure and drive on the rollers allows for efficient, demand-driven operation and improved energy efficiency.
• Reduces belt tension (strain), prolonging belt life and minimizing breakdowns.
• Improves operational safety and cleanliness by enclosing the material during conveyance and minimizing spillage.
• Allows for scalable solutions in tight or space-constrained environments and eliminates the need for multiple conveyors or lifts.

Patent Abstract

The cover belt conveyor is provided with a respective support belt (5) designed as a continuous belt and a cover belt (6), which are each guided around a deflection drum (7 and 8) and a respective rotatable drive drum (9 and 10), such that they are guided opposite one another in a steep or perpendicular conveying region, and such that a conveyor belt can be conveyed between the support belt (5) and the cover belt (6) with a translational movement of the support belt (5) and the cover belt (6) in the direction of the respective drive drum (9 and 10). In the steep or perpendicular conveying region (11), cylindrical elements (1.1 and 1.2) are arranged in pairs in contact with the outer surface of the support belt (5) and the cover belt (6) on opposite sides with the application of a compressive force, which are rotatably mounted at a right angle to the conveying direction, and a rotational drive engages on at least one of the cylindrical elements (1.1 and/or 1.2) of a pair. With these, traction forces can be transmitted in the conveying direction or in the opposite direction onto the support belt (5) and/or the cover belt (6).
