<P>PROBLEM TO BE SOLVED: To provide a feeding device capable of reducing electric power consumption in a servo locking time. <P>SOLUTION: A feeding device 1 includes a ball screw 21, a nut 23, a drive motor 24, a brake mechanism 25, and a control device 50, and moves a moving body 13 in a vertical direction. When recognizing a move command of rapid feed relative to the moving body 13, in work of moving the moving body 13 upward from a current position, the feeding device 1 moves the moving body 13 over a target movement position relative to the move command of rapid feed and thereafter reverses the moving direction to move the moving body 13 to the target movement position and stop the moving body 13 at the target movement position, and on the other hand, in work of the moving body 13 downward from a current position, the feeding device 1 moves the moving body 13 directly to a target movement position and stops the moving body 13 at the target movement position, and thereafter maintains the position of the moving body 13 at a stop position by the drive motor 24 and brakes the movement of the moving body 13 by the brake mechanism 25. <P>COPYRIGHT: (C)2012,JPO&INPIT |
