Assembly and accumulation section for gate valves

The system needed to transport the valves to the customers dipping station where they would be checked for leaks. Three valves are processed on each pallet, making a total weight of up to 250 kg per pallet. The pallets had to have the option to be stopped at the assembly stations. The conveying path needed to be at an ergonomic working height and be secured in accordance with accident prevention regulations (UVV).

The transfer system supplied by mk was constructed out of chain conveyors and accumulating roller chain conveyors. The profile series used was selected to suit the loads being processed. The conveyors form a circuit on which the alignment of the pallets always remains the same, meaning that there was no need for rotating elements.

The pallets are stopped for processing at the assembly stations. Here, the pallets are aligned longitudinally to the conveying direction, allowing workers to easily reach every workpiece. Pressing a button releases the pallet again.

On the buffering section, the pallets are transported transversely to the conveying direction. This allows a large number of pallets to be buffered one behind the other in a small space. At the transfer to the customers dipping station, the pallets are stopped again and transported further as soon as the dipping station becomes free again. The controller and sensors were installed by the customer themselves.

The customer benefitted from the considerable experience of mk in transfer and circulation systems and could rely on them to understand the requirements and execute the best solution.

The KTF-P 2010 chain conveyor is a conveyor system for moderate loads and is ideally suited for transporting workpiece carriers. Its large selection of drives makes it extremely flexible, and it is usually used as the basis for constructing transfer lines. It is available as a single, dual or multiple line system with either a simple roller chain or a duplex roller chain for higher loads and a larger support surface.

The various chains and wear strip guides allow the workpiece to be optimally placed on the conveyor, while their excellent anti-frictional properties make them extremely low maintenance and sturdy.

Longitudinal slots in the mk 2010 profile beam provide flexible options for connecting struts, guides, sensors and components from the mk profile system.

Like all chain conveyors, the system can be equipped with an optional tensioning device and continuous lubrication device.

The wear and guide strips that support and guide the timing belt are made from ultra-high-molecular weight polyethylene (PE-UHMW), which provides a low friction coefficient with excellent wear characteristics over a wide temperature range (up to 65C over extended periods).
