other Embodiment approach

[0123] The above-mentioned embodiment is an example of a preferable embodiment of the present invention, but it is not limited thereto, and various modifications can be made without changing the gist of the present invention.

[0124] In the above-described embodiment, the vertical motor control unit 81 controls one of the two vertical driving motors 20 by speed control and torque control. In addition, for example, the up-and-down motor control unit 81 may control a vertical motor using position control and torque control based on the rotational position of the up-and-down drive motor 20 calculated by integrating the rotational speed detected by the speed detection means. A motor 20 for driving up and down the table.

[0125] Similarly, in the above-mentioned embodiment, the horizontal motor control unit 82 controls one motor 40 for horizontal driving through speed control and torque control, and controls the other motor 40 for horizontal driving through speed control and torq...

Abstract

An industrial robot, can be miniaturized and has low cost since the robot carries large-scale objects. The industrial robot comprises hands for loading the objects, arms connected with the hands, support members for supporting the arms, a top and bottom drive mechanism for driving the support member to move up and down and a control portion (80) for controlling the top and bottom drive mechanism.The top and bottom drive mechanism comprises two motors (20) for driving, the control portion (80) comprises a motor control portion (81) for controlling two motors (20) for driving. The motor controlportion (81) can singly control one motor (20) for driving and the other motor (20) for driving.

Description

technical field [0001] The present invention relates to an industrial robot that transports a predetermined object to be transported. Background technique [0002] Conventionally, industrial robots that carry prescribed objects have been widely used. As such an industrial robot, there is known an industrial robot including a hand for holding an object to be conveyed, an arm for holding the hand, and a ball screw for moving the arm up and down (for example, refer to Patent Document 1). In the industrial robot described in Patent Document 1, one motor is connected to the ball screw, and the ball screw is driven by one motor. [0003] In addition, although it is not an industrial robot that transports objects to be transported, there is also known an industrial robot that can move the base of the main body of the robot in the horizontal direction (for example, refer to Patent Document 2). The industrial robot described in this patent document 2 includes a rack and a pinion fo...
