Claims (1)

[Claims for Utility Model Registration] 1. A distributor that distributes powder and granular material conveyed by airflow through a transportation path to a plurality of branch paths together with the airflow, including a cylindrical distributor body and a cylindrical distributor body; A rotor disposed rotatably and a driving means for rotating the rotor by a predetermined angle are provided in the distributor body, one end opening on the inner surface of the distributor body and the other end opening on the outer surface of the distributor body. A plurality of branch holes are formed at appropriate intervals in the circumferential direction, and the rotor is provided with communication holes that selectively communicate with the transport channel and the branch holes. A distributor characterized in that: 2. A distributor that distributes powder and granular material transported by airflow through a transportation path to a plurality of branch paths together with the airflow, which includes a cylindrical distributor body, a rotor that rotatably fits into the distributor body, and , a driving means for rotating the rotor by a predetermined angle is provided in the distributor body, and the plurality of branches are provided in the distributor body, with one end opening on the inner periphery of the distributor body and the other end opening on the outer periphery of the distributor body. A plurality of branch holes are formed in the rotor at appropriate intervals in the circumferential direction, and one end thereof is opened at the center of one end surface of the rotor, and the other end is opened at the outer periphery of the rotor. A distributor characterized in that a communication hole is formed to selectively communicate the path and the branch hole. 3. In a distributor that distributes powder and granular material transported by airflow through a transportation path to a plurality of branch paths together with the airflow, a cylindrical distributor body having a closing part on one end side, and a tube inside the distributor body. A rotor is arranged so that one end face faces the closed part with a slight distance therebetween, and a drive means for rotating the rotor by a predetermined angle is provided, A plurality of branch holes are formed in the rotor at appropriate intervals in the circumferential direction, each communicating with a plurality of branch passages, one end of which opens at one end surface of the rotor, and the other end of which opens at the center of the other end surface of the rotor. a communication hole that selectively communicates the transport path with the branch hole, and a bearing that rotatably supports the rotor is disposed in an annular space between the outer peripheral surface of the rotor and the distributor body. A distributor characterized in that the compressed air for sealing is supplied to the annular space from the other end side of the distributor main body.
