Problems solved by technology

However, if the technology of the patent literature is applied to a system in which a worker and a robot share a workspace, there is a problem that it is difficult for the worker to recognize the interference area and determine whether it is in a situation where the worker can work in the interference area

Embodiment Construction

[0010] The technical solutions of the present invention will be further elaborated below in conjunction with the embodiments.

[0011] An access control system in which a robot system is established in a system area, which according to the present embodiment has an outline in the shape of a rectangular parallelepiped and is substantially divided into two three-dimensional areas by a virtual boundary (boundary plane), which are horizontally adjacently arranged in the first direction X. Note that while it is not necessary to install a substantial fence at the boundary, a low fence or marker of a height that does not interfere with the robot is installed. One of the two three-dimensional areas is the workspace where the robot works, in the following it is referred to as the "robot area". The other of these two three-dimensional areas is the workspace shared by robots and workers, in the following, it is called "distractor". In the interference area, robots and workers work alte...

Abstract

The invention discloses an access control system, which is configured to manage access to an interference area by staff, wherein devices shared by the staff and a robot include indicator lights distributed at least in four directions from the center of the interference area, a gate to open and close the interference area, a locking device to lock and unlock the gate, and a control unit, which controls the indicator lights and the locking device corresponding to operation of the robot. The access control system disclosed by the invention allows the staff to identify the interference area and determine whether it is possible to work in the interference area.

Description

technical field [0001] The invention belongs to the field of systems for managing workers' access to a workspace shared by workers and industrial robots, and in particular relates to an access control system. Background technique [0002] Now, traditionally, the operating area of ​​an industrial robot is surrounded by a safety fence, and the safety fence separates the worker from the industrial robot. In recent years, due to the improvement of the control ability of industrial robots, the sharing of workspace between workers and industrial robots can theoretically be realized. However, if the industrial robot is enclosed by a safety fence, it is not easy for workers to approach the interference area. [0003] On the other hand, a system has been proposed that avoids interference between industrial robots and workers by monitoring workers and objects entering the area around industrial robots without installing existing safety fences. For example, the system disclosed in th...
