Patent ID: 8447426

Claim:
An installation comprising: a machine for packaging products; a robotic palleting station including a robot that takes cases filled with said products at an output of said machine for packaging, and arranges said products on a pallet according to a predetermined diagram, by means of a gripping head, the pallet adjacent to an exit of a closed enclosure in which said machine for packaging and said palleting station are arranged, said enclosure having lateral walls, a rear wall through which cartons used for a converting operation of said cases enter said closed enclosure, and a front wall which is provided with a door providing access to said palleting station from outside said closed enclosure; means for limiting the range of movement of said robot in said closed enclosure in order to limit displacements of the gripping head to be within a restricted space which does not overlap with a safety space which is defined according to a minimum distance measured using a means for detecting intrusion which is located on said door, said means for limiting the range of movement of said robot comprising: an electric cam, which limits an amplitude of the movement of said robot around its main axis, a switching member, for indicating a request for intervention of an operator to access the palleting station in order to remove the full pallet and to set an empty pallet, a steering control, which activates said electric cam, based on an indication of the switching member, to operate said robot in said restricted space contained inside an authorised volume V of movement and programmed on said steering control, wherein said restricted space, in which the robot is limited to operate during intervention of an operator, comprises at least one buffer zone that includes a platform for temporarily setting down the cases produced by the machine for packaging, said platform accessed by said robot during the operation of extracting the full pallet and during setting of the empty pallet to be filled.
