Abstract:
A solid matter loading method in a continuous conveying type bag-filling packaging machine wherein:upon loading a solid matter into bags which are held at both ends thereof by grippers and are continuously and rectilinearly conveyed in a horizontal direction with said bags in a vertical attitude in said continuous conveying type bag-filling packaging machine, said solid matter is loaded into a bag by: an upper hopper which performs a reciprocating swinging motion along a conveying direction of said bags and about a point located near a center of an upper portion of said upper hopper, and a lower hopper which is positioned beneath said upper hopper and performs a reciprocating motion along said conveying direction of said bags; wherein when said upper hopper swings in said conveying direction of said bags and said lower hopper is moved in said conveying direction of said bags, said upper hopper swings and said lower hopper is moved in synchronization with a conveyance of said bag, and said solid matter drops and is loaded into said bag by being guided by said upper hopper and lower hopper, and said lower hopper is movable upward and downward, and when said lower hopper is moved in synchronization with said conveyance of said bag in said conveying direction of said bags, said lower hopper is moved downward to a position where an opening at a lower end of said lower hopper is inserted into a mouth of said bag.
