Method for dosing of material by producing negative pressure atmosphere in parts of conveyor, involves supplying material of conveyor without influence of gravity on material feed to conveyor

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

This patent describes a method for dosing materials into a conveyor system by creating a negative pressure (vacuum) atmosphere in certain parts of the conveyor. By using negative pressure, materials can be supplied to the conveyor without the influence of gravity, which is particularly useful for handling materials that do not flow well by themselves.

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

• Feeding powders or granules with poor flow properties into production lines
• Dosing plastic pellets or resins into extrusion or molding machinery
• Automated additive dispensing in chemical or pharmaceutical manufacturing
• Handling delicate or lightweight materials that cannot be managed with traditional gravity-fed conveyors

BenefitsContent extracted from patent full text and abstract with AI.

• Improves dosing precision for materials with low flowability
• Reduces material loss and blockages by minimizing reliance on gravity
• Allows for more consistent and controlled material feed in automated systems
• Expands the range of processable materials in existing conveyor systems
• Enhances safety and cleanliness by containing dust and fine particles through negative pressure

Patent Abstract

The method involves supplying the material of a conveyor, particularly a longitudinal conveyor without influence of gravity on the material feed to the conveyor. The negative pressure takes place at the conveyor in conveying direction downstream of a supply of the material to the longitudinal conveyor. The supply of material takes place to the conveyor with respect to the conveying direction of the material by the conveyor upstream to a connection of a vacuum unit with the conveyor. An independent claim is also included for a dosing unit, particularly for materials with low flowability.
