Conveyor Chain - Tsubaki

Free FlowChainA free flow conveyor system allows you to stop conveyed objects (with a stopper), while the chain runs continuously underneath.After the stopper is released, conveying resumes (Figure 1). It is possible to get free flow function even with ANSI/BS standard RSroller chains by placing conveyed objects directly on the chains. However, during accumulation, the chain will slide underneath theconveyed object. This may leave marks on the bottom of conveyed objects, and may eventually lead to excessive chain wear.Free flow chains were developed to eliminate the possibility of damaging conveyed objects during the accumulating mode. Thesechains are equipped with rollers that support conveyed objects. When accumulating, freely rotating rollers are in contact with thebottom side of goods conveyed, which ensures smooth and damage-free operation. The types of/relationships between the variouskinds of free flow chains are illustrated in the diagrams below.SectionFigure 1Free Flow Conveyor SystemDirection of TravelBAccumulation Transfer Accumulation TransferFigure 2Types of Free Flow ChainsRS RollerChainAvailable withAttachmentsSide RollerChainNarrowSpaceTop RollerChainCenter Roller(Single Plus)Chain}Chains to be two strands,located at both sides ofconveyor.
