Abstract
A rotary take-out apparatus for removing blow-molded articles from rotary blow-molding machine molds. The apparatus includes a rotary take-out carrousel and a take-out carrousel drive configured to rotate the take-out carrousel. Pick-up stations on the take-out carrousel rotate along a circular pick-up station path. Each station includes a pick-up head array comprising at least one pick-up head. Fluid cylinders are supported on the take-out carrousel and are each operatively connected to one of the pick-up head arrays. Each cylinder is configured to move a pick-up head array between extended and retracted positions when differential fluid pressure is directed to respective first and second chambers in the cylinder. Each pick-up head is configured to releasably grasp a blow-molded article. Cylinder valves are supported on the take-out carrousel and are connected between each cylinder and a source of differential fluid pressure. Each cylinder valve alternately diverts differential fluid pressure to the first and second chambers of a cylinder. A controller coordinates the motions of the pick-up heads, take-out carrousel, and mold carrousel to grasp and remove blow-molded articles from the molds and to release them at a point spaced from the mold carrousel.
