Vials are conveyed from the infeed conveyor to the discharge conveyor via the product accumulation belt. Accumulation happens when product backs up on the discharge conveyor and onto the accumulation belt. Product can continue to fill the accumulation belt until the infeed conveyor backs up. When the product flow at the discharge resumes, the vials feed out single file. The combination of the speed differential between the conveyor lanes and the anti-bridging belt separate the product and feed them out single file automatically. The standard Accumulator can handle vials with speeds up to 1000 vials per minute for small vials. Other models are available to be compatible with cleanroom requirements. Accumulation is determined by vial size.
