Embodiment Construction

[0035] Fig. 1 shows an industrial robot system according to a first embodiment of the present invention. The robot system includes: a manipulator 1; a control unit 2 for controlling the manipulator 2; and a portable operator control device 4, hereinafter referred to as TPU (Teach Pendant Unit), for teaching and manually operating the manipulator. The control unit 2 comprises a switch 3 for switching between automatic and manual mode. The TPU communicates with the control unit 3 via a data link, eg a wireless data link. The TPU includes a display screen 6 , function keys, a joystick 7 , an emergency stop button 8 and an enabling device 9 . The TPU also includes an antenna and a radio module for wireless communication with the control unit 2 . The joystick 7 is used to control the movement of the manipulator when manually operating the robot.

[0036] The enabling means 9 comprise a button 12 which must be pressed by the operator to enable manual control of the robot via the ...

Abstract

An industrial robot system comprising: at least one industrial robot comprising at least one manipulator (1) located in a robot cell (10); a control unit (2) for controlling the manipulator; and a portable operator control device (4 ), which is hereinafter referred to as TPU, is used to teach or manually operate the manipulator. The system also includes: a detection unit (16a, 16b) for detecting when the TPU leaves the robot cell; and an alarm generator for alerting an operator when the TPU is detected to leave the robot cell.

Description

technical field [0001] The present invention relates to an industrial robot system comprising: an industrial robot comprising at least one manipulator and a control unit for controlling the manipulator; and a portable operator control device wirelessly connected to the control unit ( TPU). The invention also relates to a method for ensuring safety in such an industrial robot system. Background technique [0002] Industrial robots are programmed to perform work along a work path. To program or teach a robot to work, the robot is steered into position along a desired work path. These positions are stored as instructions in a memory in the control unit. During the working process of the robot, the program instructions are executed, so that the robot works as expected. [0003] The people who control the robot are called operators. Hereinafter, "user" and "operator" are synonymous. Industrial robots can work in different working modes. For example, when the robot is place...
