Assembly and accumulation section for gate valves
A customer required a pallet transfer system for the production of gate valves for water pipes , on which the valves could be assembled and buffered . The system needed to transport the valves to the customer ’ s 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 ).
Solution from mk
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 customer ’ s 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 .
Like all chain conveyors , the system can be equipped with an optional tensioning device and continuous lubrication device .
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 .
Description of KTF-P 2010 Chain Conveyor
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-highmolecular weight polyethylene ( PE-UHMW ), which provides a low friction coefficient with excellent wear characteristics over a wide temperature range ( up to 65 ° C over extended periods ).
