Abstract

A control circuit of a tray changer is interfaced with a control circuit of a robot. A tray changer control program, used for operating the tray changer, is loaded into the robot control system. The robot control system itself, or an operator manipulating an operating terminal of the robot, controls or operates the tray changer according to the tray changer control program loaded in the robot control system.

Claims

1. A method for controlling a tray changer incorporated in a robot control system, comprising:

a step of interfacing a control circuit of said tray changer with a control circuit of a robot;

a step of loading a tray changer control program into the robot control system, said tray changer control program being used for operating said tray changer; and

a step of causing said robot control system or an operating terminal of the robot to control or operate said tray changer according to said tray changer control program;

wherein

said step of causing said robot control system or the operating terminal of the robot to control or operate said tray changer according to said tray changer control program is feasible for simultaneously controlling or operating a plurality of tray changers.

2. The method for controlling the tray changer incorporated in the robot control system in accordance with claim 1, wherein

said tray changer control program includes an implementation of automatic carry in-and-out processing performed by said tray changer as well as an implementation of manual carry in-and-out operation processing performed by said tray changer, and

the control method further comprises:

a step of inhibiting said automatic carry in-and-out processing performed by said tray changer when a manual operation mode of said tray changer is selected; and

a step of inhibiting said manual carry in-and-out processing performed by said tray changer when an automatic operation mode of said tray changer is selected.

3. The method for controlling the tray changer incorporated in the robot control system in accordance with claim 2, further comprising:

a step of allowing an operator of said tray changer to select said manual operation mode or said automatic operation mode of said tray changer through an operating terminal of said robot or through an external operation device, thereby allowing said tray changer to perform said manual carry in-and-out processing when said manual operation mode is selected and perform said automatic carry in-and-out processing when said automatic operation mode is selected.
