ABSTRACT:
A continuous belt conveyor for transporting bottles to be processed includes an inclined ramp portion for elevating bottles to a moving horizontal platform portion, screw means for selectively adjusting the height of the moving horizontal platform portion without varying the length or tension of the conveyor belt, a variable pitch horizontally disposed screw guide for uniformly spacing bottles as they enter upon the moving horizontal platform, and a plurality of uniformly spaced neck gripping overhead bottle carriers mounted on a continuous overhead chain moving in synchronism with the conveyor belt, with overhead cam means adjacent to the junction between the inclined ramp portion and the horizontal platform portion of the conveyor belt for causing the overhead bottle grippers to be successively elevated over, aligned with, and then lowered onto neck locking engagement with individual bottles passing therebeneath. The overhead bottle grippers comprise a clam shell type of structure opened when elevated and closed when lowered and a surrounding rotatable cylindrical shield which holds the clam shells in locked position when lowered thereover and which also by engagement with a suitable rack produces a rotation of the bottles as they are carried thereby through a spray processing station. A synchronous drive mechanism including a feedback loop between the conveyor belt and the overhead chain conveyor maintains constant speed and physical relationship between the two continuously moving conveyor means.
