ABSTRACT:
An automated system for handling concrete pipe and for handling and cleaning the components used in the manufacture of the pipe. Once concrete pipe has cured, the system automatically removes the bell and spigot forming rings from the pipe, and cleans and oils them for reuse. At the ring removal station, the pipe is properly positioned and oriented and the rings are pulled from each end of the pipe and transported to cleaning and oiling stations where all critical surfaces of the rings are cleaned by pulverizing, chiseling and brushing the concrete residue from the rings which are then coated with oil. The automated system is designed to handle rings of different sizes without any intervention by an operator, and the system will handle rings of different diameters that are intermixed.
