  • Patent number: 11970341
    Abstract: In an article transfer facility, a drive portion includes a first Z-axis drive portion configured to move a holding portion in a Z direction, a first X-axis drive portion configured to move the holding portion in an X direction, a first Y-axis drive portion configured to move the holding portion in a Y direction, and a second X-axis drive portion configured to move a placement portion in the X direction. A control portion executes first control in which an article at a first position is placed on the placement portion, and second control in which the article placed on the placement portion is arranged at a second position. In the first control, the drive portion is controlled such that the holding portion picks up the article at the first position and moves to a position on an upper side of the placement portion, and thereafter releases the article to place the article on the placement portion.

  • Publication number: 20150326147
    Abstract: An elastic member 43 comprises a crystalline resin. The elastic member is fixed to a piezoelectric element 42 that generates vibration in response to application of an AC voltage, is in contact with a movable body 45 in use, and flexurally vibrates in response to the vibration of the piezoelectric element 42 to drive the movable body 45. The elastic member 43 may have a tooth 43b on an opposite side with respect to a side fixed to the piezoelectric element 42. The crystalline resin may be a poly(aryl ketone) resin or a poly(phenylene sulfide) resin. The piezoelectric actuator has an excellent transmission of flexural vibration. In a case where a displacement expansion element of a displacement-expanding piezoelectric actuator is formed from a crystalline resin, the actuator greatly amplifies an expansion and contraction displacement of a piezoelectric element.
