Title: Method and device for teaching/reproduction of robot system with conveyor
Inventor: KIMURA YASUSHI
IPC: B25J13/00
Filed: 1989-09-14
Abstract: PURPOSE:To perform a reproducing operation in a robot system with the same relative position kept to a work as that set in a teaching mode by driving a conveyor to teach the work transfer in a teaching mode as long as a robot stores the position data and controlling the speed of the robot in response to the speed of the conveyor in a reproduction mode. CONSTITUTION:When a robot body 1 is driven and the storage of the position data is started, a work 16 put on a conveyor 3 start to move at prescribed speed. Then the position data is stored in response to the work 16 which is transferred by the conveyor 3. In a reproduction mode, the work 16 is continuously transferred by the conveyor 3 and a sensor 7 detects the work 16. Thus a controller 8 receives the output of the sensor 7 as a robot start signal and starts the robot body 1. When the transfer speed of the conveyor 3 must be changed, a speed ratio is set as the speed magnification via a control panel 12 between the teaching and reproduction modes of the robot body 1. Then the reproduction speed of the body 1 is changed. Thus it is possible to perform a reproducing operation with the relative position relation kept between the conveyor 3 and the robot body 1 in a teaching mode.
