Anti-intrusion method in an automated system with robot

摘要

A method for making use of an automated system with a robot, including the following steps: (i) a management controller (12) authorizes the extraction of a pallet (2) and communicates information to a safety controller (11) concerning the extraction authorization, (ii) a series of presence detectors (7) sends initial height information (HLP) for a pallet (2) on which products (10) are arranged to the safety controller (11), (iii) the safety controller (11) generates reference information based on the initial information received, (iv) the presence detectors (7) send current height information for the pallet (2) to the safety controller (11), and the safety controller (11) compares the current height information to the reference information. If the current information does not correspond to the reference information, then a robot (5) is stopped and/or the safety measures of the enclosure (1) are applied.

1. A method of making use of an automated system with a robot in an enclosure equipped with at least one door providing access to at least one operator intervention station, said at least one operator intervention station being located within a work area of a robot and being adapted to accommodate a pallet, and a series of detecting means for detecting a presence in alignment along a vertical element of the enclosure, said series of detecting means being arranged at or near said door, said series of detecting means being connected to a safety controller acting on an operation of the robot and/or on safety measures applied to said enclosure, and communicating with a management controller of the automated system:
wherein according to the method: said management controller authorizes extraction of a pallet and communicates information to the safety controller concerning the extraction authorization, said series of detecting means sends initial height information about the pallet on which products are arranged to said safety controller, said safety controller generates reference information that is based on said initial height information received, at least at the moment when the pallet is extracted from the operator intervention station and when one end of the pallet is located in front of the series of detector means:
the detector means sends current height information concerning said pallet to said safety controller, andsaid safety controller compares said current height information to said reference information; and wherein, if said current height information does not match the reference information, then the robot is stopped and/or the safety measures of said enclosure are applied.
