Abstract

Conveyor track is esp. for evacuated moulding boxes using plastic foils and binder-free sand. A track with a rectangular shape is used consisting of two long sides and two short sides. The track has pairs of rails for flat-topped trolleys fitted with wheels. A cope and drag is placed on each trolley and joined to vacuum connection pipes via spring-actuated non-return valves on each trolley. Valves are also used to apply a vacuum to all the trolleys, which are moved along the long sides by four work cylinders each contg. a hollow piston rod fitted with a valve mating with similar valves on the trolleys; the piston rods are connected by flexible pipes to a vacuum pump. Two other work cylinders push the trolleys along the short sides.
