Conveyor system

摘要

A conveyor assembly having a pallet including a deformable drive pin. The drive pin is comprised of urethane and is operable to deform as the pallet engages the teeth of a pallet driving sprocket employed to drive the pallet around curved end portions of the conveyor. The deformability of the drive pin enables smoother engagement of the pallet with the pallet driving sprocket teeth when the drive pin does not fall perfectly inbetween adjacent teeth of the pallet driving sprocket. The deformable drive pin is also disposed within oversized openings allowing the drive pin to be urged outwardly by a tooth of the pallet driving sprocket as the deformable drive pin comes into contact with the tooth. The pallet further includes a drive block for holding the deformable drive pin, the drive block having leg portions operable to circumscribe at least a portion of the pallet driving sprocket. The overall length of the drive block is such that the deformable drive pin is disposed at approximately the midpoint of the total length of the drive block. The leg portions further serve to stabilize the pallet as it traverses the curved end portions of the conveyor.
