Title: Conveying device
Inventor: MORIOKA MASANORI
IPC: B66F17/00
Filed: 2000-08-28
Abstract: PROBLEM TO BE SOLVED: To provide a conveying device having high stop position precision with a simple and inexpensive structure. SOLUTION: When a screw shaft 12 is rotated by a motor 16, a base 30 is moved, detection signals are generated in sequence from a photoelectric switch 26 detecting the notch 24 provided on a chopper 22 fixed to the screw shaft 12, and the cumulative number of rotation is calculated in sequence based on the number of their occurrence. The rotating speed of the motor 16 is set to a first rotating speed until the cumulative number of rotation of the screw shaft 12 reaches a first set value or above and to a second rotating speed lower than that thereafter respectively, and the motor 16 is stopped when the cumulative number of rotation coincides with a second set value. Since the base 30 is moved at a high speed up to a fixed cumulative number of rotation requiring deceleration, the required time is shortened.  The rotating speed of the motor 16 is set to the low second rotating speed when the base 30 is moved by a set distance s, thereby a tray 10 can be stopped at a desired position with high precision.

Abstract: PROBLEM TO BE SOLVED: To easily move a tip of a robot over a desired section with constant velocity. SOLUTION: When a movement command is set to include a constant velocity starting position and a constant velocity end position, the robot controller calculates acceleration and deceleration times in a trapezoidal speed pattern (S4) and then determines whether the constant velocity starting position and the constant velocity end position fall within the constant velocity section when maximum deceleration is used (S5).
