Automated system for the in-line inverting, transferring and filling of lab animal containment devices in areas where they are washed

An automated system for handling trays for containing laboratory animals coming from a washing machine, wherein it comprises a motor-driven roller bench, a device for inverting said trays, one or more selectively controlled devices for stopping the forward feed of said trays, one or more sensors along said motor-driven roller bench capable of detecting the presence of the trays in line with said sensors, and a central control unit for controlling and coordinating the operation of said tray inverting device and said stopping devices as a function of the signals received from said sensors wherein said tray inverting device comprises two substantially parallel plates connected by a plurality of rods arranged so that at least two or more rods are parallel and coplanar so as to form a first, lower plane substantially parallel to a supporting surface formed by a plurality of motor-driven rollers and another at least two or more parallel and coplanar rods form a second, upper plane substantially parallel to the first lower plane and positioned above the first lower plane at a distance that is adjustable by suitable gripping means, wherein the at least two or more rods of each plane are arranged to be inserted between the plurality of motor-driven rollers of the supporting surface.
