1. A component placing device comprising:

  • a plurality of nozzles that put suction paths under a negative pressure to hold components;

    a plurality of nozzle shafts that hold the plurality of nozzles at lower end portions of the nozzle shafts so as to be freely replaceable and each of which has an internal flow path leading to a corresponding one of the suction paths;

    a rotating object that holds the plurality of nozzle shafts at equal pitches on a circumference of a circle, of which a center is a rotation axis, so that the plurality of nozzle shafts rise and fall freely and the rotating object rotates about the rotation axis to move the plurality of nozzles in turn to a plurality of stations including a component holding and placing station where operation of holding the components or placing components held by the plurality of nozzles at predetermined placement positions on a workpiece is performed and a component detecting station where detection of the components held by the plurality of nozzles is performed;

    a nozzle rising and falling mechanism that causes the plurality of nozzles to rise and fall at the component holding and placing station;

    a component detector that detects the components held by the plurality of nozzles at the component detecting station;

    a negative pressure flow path that is an air flow path formed inside the rotating object and leads to an external negative pressure source;

    a positive pressure flow path that is an air flow path formed inside the rotating object and leads to an external positive pressure source;

    a contact flow path that is an air flow path formed inside the rotating object and communicates with the internal flow path of each of the plurality of nozzle shafts;

    a flow path switcher that is internally provided in the rotating object, has a spool which moves by air for power, and causes the contact flow path to selectively communicate with the negative pressure flow path and the positive pressure flow path by movement of the spool;

    a first pilot flow path and a second pilot flow path, which are internally provided in the rotating object and through which air for power to drive the spool of the flow path switcher is supplied; and

    a communication plug for power air, which comes into contact with an exterior surface of the rotating object and through which air for power is supplied to the first pilot flow path and the second pilot flow path from the outside.
