Embodiment Construction

[0039] Hereinafter, a method of handling security in a work area of ​​an industrial system, a control system for handling security in a work area of ​​an industrial system, and an industrial system including the control system will be described.

[0040] figure 1 A top view of the industrial system 10 in a first state is schematically represented. The industrial system 10 includes a work area 12, a plurality of machines 14a-14l in the work area 12, and a plurality of safety input devices 16a-16c in the work area 12 (each machine 14a-14l may also be identified by the reference numeral "14" ” and each of the secure input devices 16a-16l may also be represented by the reference numeral “16”). Examples of the machines 14b, 14c, 14d, 14e, 14f, 14i, and 14k are industrial robots, each with manipulators programmable in three or more axes. Examples of the machines 14a, 14g, 14h, and 14j are AGVs. An example of this machine 14l is a conveyor belt.

Abstract

A method of handling safety in a working area (12) of an industrial system (10), wherein at least one machine (14) is arranged to operate in the working area (12), at least one manually operable safety input device (16) is provided in the working area (12), and one or more of the at least one machine (14) and the at least one safety input device (16) is movable to different positions in the working area (12), the method comprising continuously or repeatedly determining whether one or more of the at least one the machine (14) is in proximity to one or more of the at least one safety input device (16); and associating at least one machine (14) with the at least one safety input device (16) upon determining that one or more of the at least one machine (14) is in proximity to one or more of the at least one safety input device (16), such that the at least one associated machine (14) can be brought to a safe state by means of the at least one safety input device (16).

Description

technical field [0001] The present disclosure generally relates to the safety of processes in industrial environments. In particular, a method of handling security in a work area of ​​an industrial system, a control system for handling security in a work area of ​​an industrial system, and an industrial system incorporating such a control system are provided. Background technique [0002] The work area of ​​machines in industrial systems is generally fixed and guarded by fences and associated safety systems to ensure a safe environment for operators. The trend in industry is to increase the mobility of machines in industrial systems. An example of such an industrial system is in a factory, where some AGVs (autonomous guided vehicles) move parts between robots and some AGVs move robots between workstations where the parts processed by the robots are located. The increased mobility of industrial systems' machines, such as AGVs and robots, combined with the mobility of one or...
