無人搬送車の昇降・傾斜制御装置

Japanese Patent JP7459710

B2

To provide an elevation and inclination device for an unmanned conveyance vehicle that can control both elevation and inclination by reducing an impact at a time of contact between an output shaft of an actuator and a to-be-controlled body.SOLUTION: The device includes a base 20, which is mounted on a movable unmanned conveyance vehicle 10, first through fourth actuators 31-34, which are actuators installed at each of four corners on the base 20, and whose output axes are configured to move freely in a direction perpendicular to the installation surface, a to-be-controlled body 40 installed opposite to the tip of each output shaft of the actuators 31-34, and a position control unit that extends the first through fourth actuators 31-34 by a force sufficiently small compared to a load on the to-be-controlled body 40, and controls the position of each output shaft of the first through fourth actuators 31-34 while controlling the inclination of the to-be-controlled body 40 after the tip of the output shaft of each actuator contacts and stops the to-be-controlled body 40.SELECTED DRAWING: Figure 1
