  • Application apparatus for applying cohesive material to application target
    Patent number: 9616446
    Abstract: An application apparatus includes a nozzle device (20) injecting a damping material from a nozzle hole (20a) to a vehicle body, an articulated robot (21) moving the nozzle device (20) relative to the vehicle body, a supply section including a supply pump (22), and a supply passage (27), and continuously driving the supply pump (22) to continuously supply the damping material from the supply pump (22) to the supply passage (27) in a substantially uniform amount, a return passage (33) branched from the supply passage (27) and returning the damping material to the supply pump (22), and a gun (32) and a return valve (34) switching a supply destination of the damping material between the nozzle hole (20a) and the return passage (33) based on information on applying the damping material to the vehicle body.

  • Robot system
    Patent number: 8231117
    Abstract: The present invention provides a robot system in which a robot and a positioner are combined with each other. In the robot system, footprint is reduced and a production line having a short tact time between steps is formed. The robot system includes a work object, robots that perform a work operation on the work object, and positioners that position the work object, wherein the robots are provided on frame members of the positioners.
