Abstract
The present invention reduces tact time for a pick-and-place operation by an actuator. In a housing of the actuator, an air passage being a passage of air when sucking air from a hollow part of a shaft is provided. Furthermore, a sucking valve that sucks air from the hollow part of the shaft through the air passage and a suction detecting sensor to detect that a workpiece is suctioned onto a tip of the shaft are provided in the air passage. Then, in the housing, the air passage is disposed at a position on a side opposite to a linear motion motor that moves the shaft in an axial direction of the shaft, via the shaft.
