Abstract:
A powder compression molding and assembly system comprising:a rotary disk; a plurality of molding units mounted on the rotary disk at spaced circumferential locations, each of said plurality of molding units including a cylindrical die; a lower plunger; an upper plunger; a center pin concentric with said lower plunger for defining an annular space within said die for molding powder into tubular configurations, when one of the plurality of the molding units are moved along a circular path to be aligned between the lower plunger and the upper plunger; a pair of pressure rollers provided at least at two equally spaced locations on the movement path of the plurality of molding units for pressure engagement with the upper plunger and the lower plunger respectively; a feed station for loading each cylindrical die with a powder material to be molded by pressure engagement with the upper plunger and lower plunger into a pellet; a plurality of operating units provided respectively to each of the plurality of molding units and moved along a concentric path with the molding units, for transferring and retractably positioning a case above and in alignment with the cylindrical die of each of the molding units; a plurality of insertion assembly stations mounted at an appropriate position on a movement path of the molding units for inserting molded pellets into a case operatively positioned outside of and in alignment with the cylindrical die by an operating unit; a case carrying-in unit for feeding a case to a first insertion assembly station; a case holding unit for holding and conveying a case loaded with a first molded pellet at the first insertion assembly station to a second insertion assembly station wherein the second insertion assembly station inserts a second molded pellet adjacent the first molded pellet; and a case carrying-out unit for removing a case loaded with the first and second molded pellets, thereby allowing the assembly system to automatically fill a case with a plurality of molded pellets.
