Conveying Device

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

The patent describes a conveying system that uses a magnetic drive mechanism to move belts and chains more efficiently. At least one of the drive belts is magnetic or magnetisable, and paired with a corresponding belt or component that is magnetically attracted. The magnetic force pulls the belts toward each other in the region of the conveyor's carrier section, creating a reliable friction-based (and optionally geometry-based) engagement with the load-carrying unit. This system reduces slippage and wear by ensuring firm engagement without needing excessive mechanical tension or complex structure. The invention supports a variety of conveyor types, including those using flat belts, chains, and suspended carriers.

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

• Automated manufacturing assembly lines where low-maintenance, reliable conveyors are needed.
• Airport baggage handling systems requiring high efficiency and low error rates.
• Parcel or logistics distribution centers for sorting and transporting packages.
• Bulk material handling in mining or agriculture, where conveyor reliability is critical over long distances.
• Cleanroom environments where traditional lubricants and friction-driven systems are undesirable.
• Production environments transitioning to Industry 4.0, requiring precise, synchronizable material movement.

BenefitsContent extracted from patent full text and abstract with AI.

• Minimizes conveyor belt or chain slippage, resulting in more accurate and efficient transport.
• Reduces wear and mechanical stress on key drive components, which lowers maintenance costs and increases lifespan.
• Permits a simpler and lighter supporting structure since less mechanical pre-tension is required.
• Avoids velocity fluctuation problems like the polygon effect commonly found in chain drives.
• Supports both frictional and positive (geometry-based) engagement for added flexibility and safety.
• Adaptable to a wide range of conveyor formats and can be tailored to specific industrial needs.
• Allows for safer operation: magnetic force can act as a safety release to prevent equipment damage during jams or overloads.

Patent Abstract

The invention relates to a conveying unit comprising a carrier unit (1) having a driver unit (4), which extends substantially in the movement direction (a1, a2) of the carrier unit (1) and can be moved by a drive (2). The drive (2) comprises at least two revolving drive belts (2a 2b), wherein tensioning sections (3a, 3b) of the revolving drive belts (2a 2b) are located opposite of each other and the driver unit (4) extends along a region between the tensioning sections (3a 3b). At least one of the drive belts (2a 2b) is magnetic or can be magnetized and the opposing drive belt (2a, 2b) is magnetically attracted. The revolving drive belts (2a 2b) in the region of the opposing tensioning sections (3a 3b) are pulled toward each other on the driver unit (4) by a magnetic force.
