Problems solved by technology

However, in this method, the operation needs to be stopped frequently in order to supply the object to be processed, which is inefficient.
In addition, although it is possible to use the turntable and the slide plate instead of the operator to supply the object to be processed to each work area, there is a problem that additional equipment such as the turntable, the slide plate and its control are required

Abstract

During a robot taking workpieces out of a workpiece container 2, a safety fence 2 and a photoelectric sensor 1 are valid and the robot is stopped when the safety fence 2 is opened or a beam from the photoelectric sensor 1 is cut off. A safety fence 1 and a photoelectric sensor 2 are invalid and do not hinder operation of the robot. Operation feasible state indicating lamps of workpiece feeding lamp / switch boxes 1 and 2 are turned on and off, respectively. If an operator replaces a workpiece container 1, he / she actuates an operating area entrance switch or the box 1 into an ON state to make OFF state an operation feasible signal for the robot RB on a side of the workpiece container 1. When the robot is operating on the side of the workpiece container 1, the robot can continue to operate while similarly ensuring safety of the operator.

Description

technical field [0001] The present invention relates to an automatic machine configured such that an operator supplies an object to be processed from a preparation area adjacent to each operation area to each operation area while using an automatic machine such as a robot to perform operations on the object to be processed in several operation areas. A safety device in the system to ensure the safety of the operator. Background technique [0002] When an automatic machine such as a robot is used to work on an object to be processed, in many cases the system is configured such that a working area for the automatic machine is set up near the automatic machine, and processing is prepared in advance in a preparation area adjacent to the working area. Object, from which the operator supplies the object to be processed to each work area. In such a system, of course, the operator needs to be careful not to enter the work area where the robot is working, but sometimes accidentally ...
